// This file is an amalgamation of many separate C source files from SQLite
// version 3.39.2.  By combining all the individual C code files into this
// single large file, the entire code can be compiled as a single translation
// unit.  This allows many compilers to do optimizations that would not be
// possible if the files were compiled separately.  Performance improvements
// of 5% or more are commonly seen when SQLite is compiled as a single
// translation unit.
//
// This file is all you need to compile SQLite.  To use SQLite in other
// programs, you need this file and the "sqlite3.h" header file that defines
// the programming interface to the SQLite library.  (If you do not have
// the "sqlite3.h" header file at hand, you will find a copy embedded within
// the text of this file.  Search for "Begin file sqlite3.h" to find the start
// of the embedded sqlite3.h header file.) Additional code files may be needed
// if you want a wrapper to interface SQLite with your choice of programming
// language. The code for the "sqlite3" command-line shell is also in a
// separate file. This file contains only code for the core SQLite library.

//
// Some comments have special meaning to the tools that measure test

//
//    NO_TEST                     - The branches on this line are not
//                                  measured by branch coverage.  This is
//                                  used on lines of code that actually
//                                  implement parts of coverage testing.
//
//    OPTIMIZATION-IF-TRUE        - This branch is allowed to alway be false
//                                  and the correct answer is still obtained,
//                                  though perhaps more slowly.
//
//    OPTIMIZATION-IF-FALSE       - This branch is allowed to alway be true
//                                  and the correct answer is still obtained,
//                                  though perhaps more slowly.
//
//    PREVENTS-HARMLESS-OVERREAD  - This branch prevents a buffer overread
//                                  that would be harmless and undetectable
//                                  if it did occur.

// These #defines should enable >2GB file support on POSIX if the
// underlying operating system supports it.  If the OS lacks
// large file support, or if the OS is windows, these should be no-ops.
//
// Ticket #2739:  The _LARGEFILE_SOURCE macro must appear before any
// system #includes.  Hence, this block of code must be the very first
// code in all source files.
//
// Large file support can be disabled using the -DSQLITE_DISABLE_LFS switch
// on the compiler command line.  This is necessary if you are compiling
// on a recent machine (ex: Red Hat 7.2) but you want your code to work
// on an older machine (ex: Red Hat 6.0).  If you compile on Red Hat 7.2
// without this option, LFS is enable.  But LFS does not exist in the kernel
// in Red Hat 6.0, so the code won't work.  Hence, for maximum binary
// portability you should omit LFS.
//
// The previous paragraph was written in 2005.  (This paragraph is written
// on 2008-11-28.) These days, all Linux kernels support large files, so
// you should probably leave LFS enabled.  But some embedded platforms might
// lack LFS in which case the SQLITE_DISABLE_LFS macro might still be useful.
//
// Similar is true for Mac OS X.  LFS is only supported on Mac OS X 9 and later.

// The GCC_VERSION and MSVC_VERSION macros are used to
// conditionally include optimizations for each of these compilers.  A
// value of 0 means that compiler is not being used.  The
// SQLITE_DISABLE_INTRINSIC macro means do not use any compiler-specific
// optimizations, and hence set all compiler macros to 0
//
// There was once also a CLANG_VERSION macro.  However, we learn that the
// version numbers in clang are for "marketing" only and are inconsistent
// and unreliable.  Fortunately, all versions of clang also recognize the
// gcc version numbers and have reasonable settings for gcc version numbers,
// so the GCC_VERSION macro will be set to a correct non-zero value even
// when compiling with clang.

// Some C99 functions in "math.h" are only present for MSVC when its version
// is associated with Visual Studio 2013 or higher.

// Needed for various definitions...

// Macro to disable warnings about missing "break" at the end of a "case".

// For MinGW, check to see if we can include the header file containing its
// version information, among other things.  Normally, this internal MinGW
// header file would [only] be included automatically by other MinGW header
// files; however, the contained version information is now required by this
// header file to work around binary compatibility issues (see below) and
// this is the only known way to reliably obtain it.  This entire #if block
// would be completely unnecessary if there was any other way of detecting
// MinGW via their preprocessor (e.g. if they customized their GCC to define
// some MinGW-specific macros).  When compiling for MinGW, either the
// _HAVE_MINGW_H or _HAVE__MINGW_H (note the extra underscore) macro must be
// defined; otherwise, detection of conditions specific to MinGW will be
// disabled.

// For MinGW version 4.x (and higher), check to see if the _USE_32BIT_TIME_T
// define is required to maintain binary compatibility with the MSVC runtime
// library in use (e.g. for Windows XP).

// Optionally #include a user-defined header, whereby compilation options
// may be set prior to where they take effect, but after platform setup.
// If SQLITE_CUSTOM_INCLUDE=? is defined, its value names the #include
// file.

// Written by J.T. Conklin <jtc@wimsey.com> 01/17/95.
// Public domain.

// Macro to test if we're using a specific version of gcc or later.

// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
// The __CONCAT macro is a bit tricky -- make sure you don't put spaces
// in between its arguments.  Do not use __CONCAT on double-quoted strings,
// such as those from the __STRING macro: to concatenate strings just put
// them next to each other.

// GCC1 and some versions of GCC2 declare dead (non-returning) and
// pure (no side effects) functions using "volatile" and "const";
// unfortunately, these then cause warnings under "-ansi -pedantic".
// GCC >= 2.5 uses the __attribute__((attrs)) style.  All of these
// work for GNU C++ (modulo a slight glitch in the C++ grammar in
// the distribution version of 2.5.5).

// __returns_twice makes the compiler not assume the function
// only returns once.  This affects registerisation of variables:
// even local variables need to be in memory across such a call.
// Example: setjmp()

// __only_inline makes the compiler only use this function definition
// for inlining; references that can't be inlined will be left as
// external references instead of generating a local copy.  The
// matching library should include a simple extern definition for
// the function to handle those references.  c.f. ctype.h

// GNU C version 2.96 adds explicit branch prediction so that
// the CPU back-end can hint the processor and also so that
// code blocks can be reordered such that the predicted path
// sees a more linear flow, thus improving cache behavior, etc.
//
// The following two macros provide us with a way to utilize this
// compiler feature.  Use __predict_true() if you expect the expression
// to evaluate to true, and __predict_false() if you expect the
// expression to evaluate to false.
//
// A few notes about usage:
//
//	* Generally, __predict_false() error condition checks (unless
//	  you have some _strong_ reason to do otherwise, in which case
//	  document it), and/or __predict_true() `no-error' condition
//	  checks, assuming you want to optimize for the no-error case.
//
//	* Other than that, if you don't know the likelihood of a test
//	  succeeding from empirical or other `hard' evidence, don't
//	  make predictions.
//
//	* These are meant to be used in places that are run `a lot'.
//	  It is wasteful to make predictions in code that is run
//	  seldomly (e.g. at subsystem initialization time) as the
//	  basic block reordering that this affects can often generate
//	  larger code.

// Delete pseudo-keywords wherever they are not available or needed.

// The __packed macro indicates that a variable or structure members
// should have the smallest possible alignment, despite any host CPU
// alignment requirements.
//
// The __aligned(x) macro specifies the minimum alignment of a
// variable or structure.
//
// These macros together are useful for describing the layout and
// alignment of messages exchanged with hardware or other systems.

// "The nice thing about standards is that there are so many to choose from."
// There are a number of "feature test macros" specified by (different)
// standards that determine which interfaces and types the header files
// should expose.
//
// Because of inconsistencies in these macros, we define our own
// set in the private name space that end in _VISIBLE.  These are
// always defined and so headers can test their values easily.
// Things can get tricky when multiple feature macros are defined.
// We try to take the union of all the features requested.
//
// The following macros are guaranteed to have a value after cdefs.h
// has been included:
//	__POSIX_VISIBLE
//	__XPG_VISIBLE
//	__ISO_C_VISIBLE
//	__BSD_VISIBLE

// CAPI3REF: OS Interface File Virtual Methods Object
//
// Every file opened by the [sqlite3_vfs.xOpen] method populates an
// [sqlite3_file] object (or, more commonly, a subclass of the
// [sqlite3_file] object) with a pointer to an instance of this object.
// This object defines the methods used to perform various operations
// against the open file represented by the [sqlite3_file] object.
//
// If the [sqlite3_vfs.xOpen] method sets the sqlite3_file.pMethods element
// to a non-NULL pointer, then the sqlite3_io_methods.xClose method
// may be invoked even if the [sqlite3_vfs.xOpen] reported that it failed.  The
// only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
// is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element
// to NULL.
//
// The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
// [SQLITE_SYNC_FULL].  The first choice is the normal fsync().
// The second choice is a Mac OS X style fullsync.  The [SQLITE_SYNC_DATAONLY]
// flag may be ORed in to indicate that only the data of the file
// and not its inode needs to be synced.
//
// The integer values to xLock() and xUnlock() are one of
// <ul>
// <li> [SQLITE_LOCK_NONE],
// <li> [SQLITE_LOCK_SHARED],
// <li> [SQLITE_LOCK_RESERVED],
// <li> [SQLITE_LOCK_PENDING], or
// <li> [SQLITE_LOCK_EXCLUSIVE].
// </ul>
// xLock() increases the lock. xUnlock() decreases the lock.
// The xCheckReservedLock() method checks whether any database connection,
// either in this process or in some other process, is holding a RESERVED,
// PENDING, or EXCLUSIVE lock on the file.  It returns true
// if such a lock exists and false otherwise.
//
// The xFileControl() method is a generic interface that allows custom
// VFS implementations to directly control an open file using the
// [sqlite3_file_control()] interface.  The second "op" argument is an
// integer opcode.  The third argument is a generic pointer intended to
// point to a structure that may contain arguments or space in which to
// write return values.  Potential uses for xFileControl() might be
// functions to enable blocking locks with timeouts, to change the
// locking strategy (for example to use dot-file locks), to inquire
// about the status of a lock, or to break stale locks.  The SQLite
// core reserves all opcodes less than 100 for its own use.
// A [file control opcodes | list of opcodes] less than 100 is available.
// Applications that define a custom xFileControl method should use opcodes
// greater than 100 to avoid conflicts.  VFS implementations should
// return [SQLITE_NOTFOUND] for file control opcodes that they do not
// recognize.
//
// The xSectorSize() method returns the sector size of the
// device that underlies the file.  The sector size is the
// minimum write that can be performed without disturbing
// other bytes in the file.  The xDeviceCharacteristics()
// method returns a bit vector describing behaviors of the
// underlying device:
//
// <ul>
// <li> [SQLITE_IOCAP_ATOMIC]
// <li> [SQLITE_IOCAP_ATOMIC512]
// <li> [SQLITE_IOCAP_ATOMIC1K]
// <li> [SQLITE_IOCAP_ATOMIC2K]
// <li> [SQLITE_IOCAP_ATOMIC4K]
// <li> [SQLITE_IOCAP_ATOMIC8K]
// <li> [SQLITE_IOCAP_ATOMIC16K]
// <li> [SQLITE_IOCAP_ATOMIC32K]
// <li> [SQLITE_IOCAP_ATOMIC64K]
// <li> [SQLITE_IOCAP_SAFE_APPEND]
// <li> [SQLITE_IOCAP_SEQUENTIAL]
// <li> [SQLITE_IOCAP_UNDELETABLE_WHEN_OPEN]
// <li> [SQLITE_IOCAP_POWERSAFE_OVERWRITE]
// <li> [SQLITE_IOCAP_IMMUTABLE]
// <li> [SQLITE_IOCAP_BATCH_ATOMIC]
// </ul>
//
// The SQLITE_IOCAP_ATOMIC property means that all writes of
// any size are atomic.  The SQLITE_IOCAP_ATOMICnnn values
// mean that writes of blocks that are nnn bytes in size and
// are aligned to an address which is an integer multiple of
// nnn are atomic.  The SQLITE_IOCAP_SAFE_APPEND value means
// that when data is appended to a file, the data is appended
// first then the size of the file is extended, never the other
// way around.  The SQLITE_IOCAP_SEQUENTIAL property means that
// information is written to disk in the same order as calls
// to xWrite().
//
// If xRead() returns SQLITE_IOERR_SHORT_READ it must also fill
// in the unread portions of the buffer with zeros.  A VFS that
// fails to zero-fill short reads might seem to work.  However,
// failure to zero-fill short reads will eventually lead to
// database corruption.

//
// An instance of the sqlite3_vfs object defines the interface between
// the SQLite core and the underlying operating system.  The "vfs"
// in the name of the object stands for "virtual file system".  See
// the [VFS | VFS documentation] for further information.
//
// The VFS interface is sometimes extended by adding new methods onto
// the end.  Each time such an extension occurs, the iVersion field
// is incremented.  The iVersion value started out as 1 in
// SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2
// with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased
// to 3 with SQLite [version 3.7.6] on [dateof:3.7.6].  Additional fields
// may be appended to the sqlite3_vfs object and the iVersion value
// may increase again in future versions of SQLite.
// Note that due to an oversight, the structure
// of the sqlite3_vfs object changed in the transition from
// SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0]
// and yet the iVersion field was not increased.
//
// The szOsFile field is the size of the subclassed [sqlite3_file]
// structure used by this VFS.  mxPathname is the maximum length of
// a pathname in this VFS.
//
// Registered sqlite3_vfs objects are kept on a linked list formed by
// the pNext pointer.  The [sqlite3_vfs_register()]
// and [sqlite3_vfs_unregister()] interfaces manage this list
// in a thread-safe way.  The [sqlite3_vfs_find()] interface
// searches the list.  Neither the application code nor the VFS
// implementation should use the pNext pointer.
//
// The pNext field is the only field in the sqlite3_vfs
// structure that SQLite will ever modify.  SQLite will only access
// or modify this field while holding a particular static mutex.
// The application should never modify anything within the sqlite3_vfs
// object once the object has been registered.
//
// The zName field holds the name of the VFS module.  The name must
// be unique across all VFS modules.
//
// [[sqlite3_vfs.xOpen]]
// ^SQLite guarantees that the zFilename parameter to xOpen
// is either a NULL pointer or string obtained
// from xFullPathname() with an optional suffix added.
// ^If a suffix is added to the zFilename parameter, it will
// consist of a single "-" character followed by no more than
// 11 alphanumeric and/or "-" characters.
// ^SQLite further guarantees that
// the string will be valid and unchanged until xClose() is
// called. Because of the previous sentence,
// the [sqlite3_file] can safely store a pointer to the
// filename if it needs to remember the filename for some reason.
// If the zFilename parameter to xOpen is a NULL pointer then xOpen
// must invent its own temporary name for the file.  ^Whenever the
// xFilename parameter is NULL it will also be the case that the
// flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
//
// The flags argument to xOpen() includes all bits set in
// the flags argument to [sqlite3_open_v2()].  Or if [sqlite3_open()]
// or [sqlite3_open16()] is used, then flags includes at least
// [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE].
// If xOpen() opens a file read-only then it sets *pOutFlags to
// include [SQLITE_OPEN_READONLY].  Other bits in *pOutFlags may be set.
//
// ^(SQLite will also add one of the following flags to the xOpen()
// call, depending on the object being opened:
//
// <ul>
// <li>  [SQLITE_OPEN_MAIN_DB]
// <li>  [SQLITE_OPEN_MAIN_JOURNAL]
// <li>  [SQLITE_OPEN_TEMP_DB]
// <li>  [SQLITE_OPEN_TEMP_JOURNAL]
// <li>  [SQLITE_OPEN_TRANSIENT_DB]
// <li>  [SQLITE_OPEN_SUBJOURNAL]
// <li>  [SQLITE_OPEN_SUPER_JOURNAL]
// <li>  [SQLITE_OPEN_WAL]
// </ul>)^
//
// The file I/O implementation can use the object type flags to

// CAPI3REF: OS Interface Object
//
// An instance of the sqlite3_vfs object defines the interface between
// the SQLite core and the underlying operating system.  The "vfs"
// in the name of the object stands for "virtual file system".  See
// the [VFS | VFS documentation] for further information.
//
// The VFS interface is sometimes extended by adding new methods onto
// the end.  Each time such an extension occurs, the iVersion field
// is incremented.  The iVersion value started out as 1 in
// SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2
// with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased
// to 3 with SQLite [version 3.7.6] on [dateof:3.7.6].  Additional fields
// may be appended to the sqlite3_vfs object and the iVersion value
// may increase again in future versions of SQLite.
// Note that due to an oversight, the structure
// of the sqlite3_vfs object changed in the transition from
// SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0]
// and yet the iVersion field was not increased.
//
// The szOsFile field is the size of the subclassed [sqlite3_file]
// structure used by this VFS.  mxPathname is the maximum length of
// a pathname in this VFS.
//
// Registered sqlite3_vfs objects are kept on a linked list formed by
// the pNext pointer.  The [sqlite3_vfs_register()]
// and [sqlite3_vfs_unregister()] interfaces manage this list
// in a thread-safe way.  The [sqlite3_vfs_find()] interface
// searches the list.  Neither the application code nor the VFS
// implementation should use the pNext pointer.
//
// The pNext field is the only field in the sqlite3_vfs
// structure that SQLite will ever modify.  SQLite will only access
// or modify this field while holding a particular static mutex.
// The application should never modify anything within the sqlite3_vfs
// object once the object has been registered.
//
// The zName field holds the name of the VFS module.  The name must
// be unique across all VFS modules.
//
// [[sqlite3_vfs.xOpen]]
// ^SQLite guarantees that the zFilename parameter to xOpen
// is either a NULL pointer or string obtained
// from xFullPathname() with an optional suffix added.
// ^If a suffix is added to the zFilename parameter, it will
// consist of a single "-" character followed by no more than
// 11 alphanumeric and/or "-" characters.
// ^SQLite further guarantees that
// the string will be valid and unchanged until xClose() is
// called. Because of the previous sentence,
// the [sqlite3_file] can safely store a pointer to the
// filename if it needs to remember the filename for some reason.
// If the zFilename parameter to xOpen is a NULL pointer then xOpen
// must invent its own temporary name for the file.  ^Whenever the
// xFilename parameter is NULL it will also be the case that the
// flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
//
// The flags argument to xOpen() includes all bits set in
// the flags argument to [sqlite3_open_v2()].  Or if [sqlite3_open()]
// or [sqlite3_open16()] is used, then flags includes at least
// [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE].
// If xOpen() opens a file read-only then it sets *pOutFlags to
// include [SQLITE_OPEN_READONLY].  Other bits in *pOutFlags may be set.
//
// ^(SQLite will also add one of the following flags to the xOpen()
// call, depending on the object being opened:
//
// <ul>
// <li>  [SQLITE_OPEN_MAIN_DB]
// <li>  [SQLITE_OPEN_MAIN_JOURNAL]
// <li>  [SQLITE_OPEN_TEMP_DB]
// <li>  [SQLITE_OPEN_TEMP_JOURNAL]
// <li>  [SQLITE_OPEN_TRANSIENT_DB]
// <li>  [SQLITE_OPEN_SUBJOURNAL]
// <li>  [SQLITE_OPEN_SUPER_JOURNAL]
// <li>  [SQLITE_OPEN_WAL]
// </ul>)^
//
// The file I/O implementation can use the object type flags to
// change the way it deals with files.  For example, an application
// that does not care about crash recovery or rollback might make
// the open of a journal file a no-op.  Writes to this journal would
// also be no-ops, and any attempt to read the journal would return

// ^SQLite will never invoke xInit() more than once without an intervening

// ^SQLite invokes the xCreate() method to construct a new cache instance.

// ^The third argument to xCreate(), bPurgeable, is true if the cache being

// false if it is used for an in-memory database. The cache implementation
// does not have to do anything special based with the value of bPurgeable;

// [[the xPagecount() page cache methods]]
// The xPagecount() method must return the number of pages currently

// single database page.  The pExtra element of sqlite3_pcache_page will be
// a pointer to the szExtra bytes of extra storage that SQLite has requested
// for each entry in the page cache.
//
// The page to be fetched is determined by the key. ^The minimum key value
// is 1.  After it has been retrieved using xFetch, the page is considered
// to be "pinned".
//
// If the requested page is already in the page cache, then the page cache

// ^If the discard parameter is
// zero, then the page may be discarded or retained at the discretion of

// may choose to evict unpinned pages at any time.

// CAPI3REF: Rebasing changesets
// EXPERIMENTAL
//
// Suppose there is a site hosting a database in state S0. And that
// modifications are made that move that database to state S1 and a
// changeset recorded (the "local" changeset). Then, a changeset based
// on S0 is received from another site (the "remote" changeset) and
// applied to the database. The database is then in state
// (S1+"remote"), where the exact state depends on any conflict
// resolution decisions (OMIT or REPLACE) made while applying "remote".
// Rebasing a changeset is to update it to take those conflict
// resolution decisions into account, so that the same conflicts
// do not have to be resolved elsewhere in the network.
//
// For example, if both the local and remote changesets contain an
// INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":
//
//   local:  INSERT INTO t1 VALUES(1, 'v1');
//   remote: INSERT INTO t1 VALUES(1, 'v2');
//
// and the conflict resolution is REPLACE, then the INSERT change is
// removed from the local changeset (it was overridden). Or, if the
// conflict resolution was "OMIT", then the local changeset is modified
// to instead contain:
//
//           UPDATE t1 SET b = 'v2' WHERE a=1;
//
// Changes within the local changeset are rebased as follows:
//
// <dl>
// <dt>Local INSERT<dd>
//   This may only conflict with a remote INSERT. If the conflict
//   resolution was OMIT, then add an UPDATE change to the rebased
//   changeset. Or, if the conflict resolution was REPLACE, add
//   nothing to the rebased changeset.
//
// <dt>Local DELETE<dd>
//   This may conflict with a remote UPDATE or DELETE. In both cases the
//   only possible resolution is OMIT. If the remote operation was a
//   DELETE, then add no change to the rebased changeset. If the remote
//   operation was an UPDATE, then the old.* fields of change are updated
//   to reflect the new.* values in the UPDATE.
//
// <dt>Local UPDATE<dd>
//   This may conflict with a remote UPDATE or DELETE. If it conflicts
//   with a DELETE, and the conflict resolution was OMIT, then the update
//   is changed into an INSERT. Any undefined values in the new.* record
//   from the update change are filled in using the old.* values from
//   the conflicting DELETE. Or, if the conflict resolution was REPLACE,
//   the UPDATE change is simply omitted from the rebased changeset.
//
//   If conflict is with a remote UPDATE and the resolution is OMIT, then
//   the old.* values are rebased using the new.* values in the remote
//   change. Or, if the resolution is REPLACE, then the change is copied
//   into the rebased changeset with updates to columns also updated by
//   the conflicting remote UPDATE removed. If this means no columns would
//   be updated, the change is omitted.
// </dl>
//
// A local change may be rebased against multiple remote changes
// simultaneously. If a single key is modified by multiple remote
// changesets, they are combined as follows before the local changeset
// is rebased:
//
// <ul>
//    <li> If there has been one or more REPLACE resolutions on a
//         key, it is rebased according to a REPLACE.
//
//    <li> If there have been no REPLACE resolutions on a key, then
//         the local changeset is rebased according to the most recent
//         of the OMIT resolutions.
// </ul>
//
// Note that conflict resolutions from multiple remote changesets are
// combined on a per-field basis, not per-row. This means that in the
// case of multiple remote UPDATE operations, some fields of a single
// local change may be rebased for REPLACE while others are rebased for
// OMIT.
//
// In order to rebase a local changeset, the remote changeset must first
// be applied to the local database using sqlite3changeset_apply_v2() and
// the buffer of rebase information captured. Then:
//
// <ol>
//   <li> An sqlite3_rebaser object is created by calling
//        sqlite3rebaser_create().
//   <li> The new object is configured with the rebase buffer obtained from
//        sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
//        If the local changeset is to be rebased against multiple remote
//        changesets, then sqlite3rebaser_configure() should be called
//        multiple times, in the same order that the multiple
//        sqlite3changeset_apply_v2() calls were made.
//   <li> Each local changeset is rebased by calling sqlite3rebaser_rebase().

	// is negative, zero, or positive, where opcode is the specific opcode.

// If x is a lower-case ASCII character, then its upper-case equivalent
// is (x - 0x20). Therefore toupper() can be implemented as:

//   (x & ~(map[x]&0x20))
//
// The equivalent of tolower() is implemented using the sqlite3UpperToLower[]
// array. tolower() is used more often than toupper() by SQLite.
//
// Bit 0x40 is set if the character is non-alphanumeric and can be used in an
// SQLite identifier.  Identifiers are alphanumerics, "_", "$", and any
// non-ASCII UTF character. Hence the test for whether or not a character is
// part of an identifier is 0x46.

// that compile-time option is omitted.

// The minimum PMA size is set to this value multiplied by the database
// page size in bytes.

// Statement journals spill to disk when their size exceeds the following

// before 3.12.0).  -1 means always keep the entire statement journal in
// memory.  (The statement journal is also always held entirely in memory
// if journal_mode=MEMORY or if temp_store=MEMORY, regardless of this
// setting.)

// This file contains the C functions that implement date and time
// functions for SQLite.
//
// There is only one exported symbol in this file - the function
// sqlite3RegisterDateTimeFunctions() found at the bottom of the file.
// All other code has file scope.
//
// SQLite processes all times and dates as julian day numbers.  The
// dates and times are stored as the number of days since noon
// in Greenwich on November 24, 4714 B.C. according to the Gregorian
// calendar system.
//
// 1970-01-01 00:00:00 is JD 2440587.5
// 2000-01-01 00:00:00 is JD 2451544.5
//
// This implementation requires years to be expressed as a 4-digit number
// which means that only dates between 0000-01-01 and 9999-12-31 can
// be represented, even though julian day numbers allow a much wider
// range of dates.
//
// The Gregorian calendar system is used for all dates and times,
// even those that predate the Gregorian calendar.  Historians usually
// use the julian calendar for dates prior to 1582-10-15 and for some
// dates afterwards, depending on locale.  Beware of this difference.
//

// This file contains the C functions that implement a memory

// This version of the memory allocation subsystem omits all

// This memory allocator uses the following algorithm:
//
//   1.  All memory allocation sizes are rounded up to a power of 2.
//
//   2.  If two adjacent free blocks are the halves of a larger block,
//       then the two blocks are coalesced into the single larger block.
//
//   3.  New memory is allocated from the first available free block.
//
// This algorithm is described in: J. M. Robson. "Bounds for Some Functions
// Concerning Dynamic Storage Allocation". Journal of the Association for
// Computing Machinery, Volume 21, Number 8, July 1974, pages 491-499.
//
// Let n be the size of the largest allocation divided by the minimum
// allocation size (after rounding all sizes up to a power of 2.)  Let M
// be the maximum amount of memory ever outstanding at one time.  Let
// N be the total amount of memory available for allocation.  Robson
// proved that this memory allocator will never breakdown due to
// fragmentation as long as the following constraint holds:
//
//      N >=  M*(1 + log2(n)/2) - n + 1
//
// The sqlite3_status() logic tracks the maximum values of n and M so
// that an application can, at any time, verify this constraint.

//     attempts to encode a value between 0x00 and 0x7f is rendered as 0xfffd.

//     If a multi-byte character attempts to encode a value between
//     0xd800 and 0xe000 then it is rendered as 0xfffd.
//
//  *  Bytes in the range of 0x80 through 0xbf which occur as the first
//     byte of a character are interpreted as single-byte characters
//     and rendered as themselves even though they are technically
//     invalid characters.
//
//  *  This routine accepts over-length UTF8 encodings
//     for unicode values 0x80 and greater.  It does not change over-length
//     encodings to 0xfffd as some systems recommend.

//
// This file contains the VFS implementation for unix-like operating systems
// include Linux, MacOSX, *BSD, QNX, VxWorks, AIX, HPUX, and others.
//
// There are actually several different VFS implementations in this file.
// The differences are in the way that file locking is done.  The default
// implementation uses Posix Advisory Locks.  Alternative implementations
// use flock(), dot-files, various proprietary locking schemas, or simply
// skip locking all together.
//
// This source file is organized into divisions where the logic for various
// subfunctions is contained within the appropriate division.  PLEASE
// KEEP THE STRUCTURE OF THIS FILE INTACT.  New code should be placed
// in the correct division and should be clearly labeled.
//
// The layout of divisions is as follows:
//
//   *  General-purpose declarations and utility functions.
//   *  Unique file ID logic used by VxWorks.
//   *  Various locking primitive implementations (all except proxy locking):
//      + for Posix Advisory Locks
//      + for no-op locks
//      + for dot-file locks
//      + for flock() locking
//      + for named semaphore locks (VxWorks only)
//      + for AFP filesystem locks (MacOSX only)
//   *  sqlite3_file methods not associated with locking.
//   *  Definitions of sqlite3_io_methods objects for all locking
//      methods plus "finder" functions for each locking method.
//   *  sqlite3_vfs method implementations.
//   *  Locking primitives for the proxy uber-locking-method. (MacOSX only)
//   *  Definitions of sqlite3_vfs objects for all locking methods
//      plus implementations of sqlite3_os_init() and sqlite3_os_end().
// #include "sqliteInt.h"

// There are various methods for file locking used for concurrency
// control:
//
//   1. POSIX locking (the default),
//   2. No locking,
//   3. Dot-file locking,
//   4. flock() locking,
//   5. AFP locking (OSX only),
//   6. Named POSIX semaphores (VXWorks only),
//   7. proxy locking. (OSX only)
//
// Styles 4, 5, and 7 are only available of SQLITE_ENABLE_LOCKING_STYLE
// is defined to 1.  The SQLITE_ENABLE_LOCKING_STYLE also enables automatic
// selection of the appropriate locking style based on the filesystem
// where the database is located.

// Use pread() and pwrite() if they are available

// standard include files.

// which is a superset of the open/fcntl flags.  Open flags and f_flags
// are inter-convertible using OFLAGS(fflags) and FFLAGS(oflags).
// Open/fcntl flags begin with O_; kernel-internal flags begin with F.
// open-only flags

// Kernel encoding of open mode; separate read and write bits that are
// independently testable: 1 greater than the above.

// XXX
// FREAD and FWRITE are excluded from the #ifdef _KERNEL so that TIOCFLUSH,
// which was documented to use FREAD/FWRITE, continues to work.

//
// Posix Advisory Locking ****************************
//
// POSIX advisory locks are broken by design.  ANSI STD 1003.1 (1996)
// section 6.5.2.2 lines 483 through 490 specify that when a process
// sets or clears a lock, that operation overrides any prior locks set
// by the same process.  It does not explicitly say so, but this implies
// that it overrides locks set by the same process using a different
// file descriptor.  Consider this test case:
//
//       int fd1 = open("./file1", O_RDWR|O_CREAT, 0644);
//       int fd2 = open("./file2", O_RDWR|O_CREAT, 0644);
//
// Suppose ./file1 and ./file2 are really the same file (because
// one is a hard or symbolic link to the other) then if you set
// an exclusive lock on fd1, then try to get an exclusive lock
// on fd2, it works.  I would have expected the second lock to
// fail since there was already a lock on the file due to fd1.
// But not so.  Since both locks came from the same process, the
// second overrides the first, even though they were on different
// file descriptors opened on different file names.
//
// This means that we cannot use POSIX locks to synchronize file access
// among competing threads of the same process.  POSIX locks will work fine
// to synchronize access for threads in separate processes, but not
// threads within the same process.
//
// To work around the problem, SQLite has to manage file locks internally
// on its own.  Whenever a new database is opened, we have to find the
// specific inode of the database file (the inode is determined by the
// st_dev and st_ino fields of the stat structure that fstat() fills in)
// and check for locks already existing on that inode.  When locks are
// created or removed, we have to look at our own internal record of the
// locks to see if another thread has previously set a lock on that same
// inode.
//
// (Aside: The use of inode numbers as unique IDs does not work on VxWorks.
// For VxWorks, we have to use the alternative unique ID system based on
// canonical filename and implemented in the previous division.)
//
// The sqlite3_file structure for POSIX is no longer just an integer file
// descriptor.  It is now a structure that holds the integer file
// descriptor and a pointer to a structure that describes the internal
// locks on the corresponding inode.  There is one locking structure
// per inode, so if the same inode is opened twice, both unixFile structures
// point to the same locking structure.  The locking structure keeps
// a reference count (so we will know when to delete it) and a "cnt"
// field that tells us its internal lock status.  cnt==0 means the
// file is unlocked.  cnt==-1 means the file has an exclusive lock.
// cnt>0 means there are cnt shared locks on the file.
//
// Any attempt to lock or unlock a file first checks the locking
// structure.  The fcntl() system call is only invoked to set a
// POSIX lock if the internal lock structure transitions between
// a locked and an unlocked state.
//
// But wait:  there are yet more problems with POSIX advisory locks.
//
// If you close a file descriptor that points to a file that has locks,
// all locks on that file that are owned by the current process are
// released.  To work around this problem, each unixInodeInfo object
// maintains a count of the number of pending locks on tha inode.
// When an attempt is made to close an unixFile, if there are
// other unixFile open on the same inode that are holding locks, the call
// to close() the file descriptor is deferred until all of the locks clear.
// The unixInodeInfo structure keeps a list of file descriptors that need to
// be closed and that list is walked (and cleared) when the last lock
// clears.
//
// Yet another problem:  LinuxThreads do not play well with posix locks.
//
// Many older versions of linux use the LinuxThreads library which is
// not posix compliant.  Under LinuxThreads, a lock created by thread
// A cannot be modified or overridden by a different thread B.
// Only thread A can modify the lock.  Locking behavior is correct
// if the appliation uses the newer Native Posix Thread Library (NPTL)
// on linux - with NPTL a lock created by thread A can override locks
// in thread B.  But there is no way to know at compile-time which
// threading library is being used.  So there is no way to know at
// compile-time whether or not thread A can override locks on thread B.
// One has to do a run-time check to discover the behavior of the
// current process.
//
// SQLite used to support LinuxThreads.  But support for LinuxThreads
// was dropped beginning with version 3.7.0.  SQLite will still work with
// LinuxThreads provided that (1) there is no more than one connection
// per database file in the same process and (2) database connections
// do not move across threads.

// An instance of the following structure serves as the key used
// to locate a particular unixInodeInfo object.

	// slightly in order to be compatible with Windows95 systems simultaneously
	// accessing the same database file, in case that is ever required.
	//
	// Symbols defined in os.h indentify the 'pending byte' and the 'reserved
	// byte', each single bytes at well known offsets, and the 'shared byte
	// range', a range of 510 bytes at a well known offset.
	//
	// To obtain a SHARED lock, a read-lock is obtained on the 'pending
	// byte'.  If this is successful, 'shared byte range' is read-locked
	// and the lock on the 'pending byte' released.  (Legacy note:  When
	// SQLite was first developed, Windows95 systems were still very common,
	// and Widnows95 lacks a shared-lock capability.  So on Windows95, a
	// single randomly selected by from the 'shared byte range' is locked.
	// Windows95 is now pretty much extinct, but this work-around for the
	// lack of shared-locks on Windows95 lives on, for backwards
	// compatibility.)
	//
	// A process may only obtain a RESERVED lock after it has a SHARED lock.
	// A RESERVED lock is implemented by grabbing a write-lock on the
	// 'reserved byte'.
	//
	// A process may only obtain a PENDING lock after it has obtained a
	// SHARED lock. A PENDING lock is implemented by obtaining a write-lock
	// on the 'pending byte'. This ensures that no new SHARED locks can be
	// obtained, but existing SHARED locks are allowed to persist. A process
	// does not have to obtain a RESERVED lock on the way to a PENDING lock.
	// This property is used by the algorithm for rolling back a journal file
	// after a crash.
	//
	// An EXCLUSIVE lock, obtained after a PENDING lock is held, is
	// implemented by obtaining a write-lock on the entire 'shared byte
	// range'. Since all other locks require a read-lock on one of the bytes
	// within this range, this ensures that no other locks are held on the

// Begin dot-file Locking ******************************
//
// The dotfile locking implementation uses the existence of separate lock
// files (really a directory) to control access to the database.  This works
// on just about every filesystem imaginable.  But there are serious downsides:
//
//    (1)  There is zero concurrency.  A single reader blocks all other
//         connections from reading or writing the database.
//
//    (2)  An application crash or power loss can leave stale lock files
//         sitting around that need to be cleared manually.
//
// Nevertheless, a dotlock is an appropriate locking mode for use if no
// other locking strategy is available.
//
// Dotfile locking works by creating a subdirectory in the same directory as
// the database and with the same name but with a ".lock" extension added.
// The existence of a lock directory implies an EXCLUSIVE lock.  All other
// lock types (SHARED, RESERVED, PENDING) are mapped into EXCLUSIVE.

// The file suffix added to the data base filename in order to create the
// lock directory.

// This routine checks if there is a RESERVED lock held on the specified
// file by this or any other process. If such a lock is held, set *pResOut
// to a non-zero value otherwise *pResOut is set to zero.  The return value
// is set to SQLITE_OK unless an I/O error occurs during lock checking.
//
// In dotfile locking, either a lock exists or it does not.  So in this
// variation of CheckReservedLock(), *pResOut is set to true if any lock
// is held on the file and false if the file is unlocked.

// Here ends the implementation of all sqlite3_file methods.
//
// End sqlite3_file Methods *******************************
//

// This division contains definitions of sqlite3_io_methods objects that
// implement various file locking strategies.  It also contains definitions
// of "finder" functions.  A finder-function is used to locate the appropriate
// sqlite3_io_methods object for a particular database file.  The pAppData
// field of the sqlite3_vfs VFS objects are initialized to be pointers to
// the correct finder-function for that VFS.
//
// Most finder functions return a pointer to a fixed sqlite3_io_methods
// object.  The only interesting finder-function is autolockIoFinder, which
// looks at the filesystem type and tries to guess the best locking
// strategy from that.
//
// For finder-function F, two objects are created:
//
//    (1) The real finder-function named "FImpt()".
//
//    (2) A constant pointer to this function named just "F".
//
//
// A pointer to the F pointer is used as the pAppData value for VFS
// objects.  We have to do this instead of letting pAppData point
// directly at the finder-function since C90 rules prevent a void*
// from be cast into a function pointer.
//
//
// Each instance of this macro generates two objects:
//
//   *  A constant sqlite3_io_methods object call METHOD that has locking
//      methods CLOSE, LOCK, UNLOCK, CKRESLOCK.
//
//   *  An I/O method finder function called FINDER that returns a pointer
//      to the METHOD object in the previous bullet.

// Here are all of the sqlite3_io_methods objects for each of the
// locking strategies.  Functions that return pointers to these methods
// are also created.

//
// Begin Proxy Locking ********************************
//
// Proxy locking is a "uber-locking-method" in this sense:  It uses the
// other locking methods on secondary lock files.  Proxy locking is a
// meta-layer over top of the primitive locking implemented above.  For
// this reason, the division that implements of proxy locking is deferred
// until late in the file (here) after all of the other I/O methods have
// been defined - so that the primitive locking methods are available
// as services to help with the implementation of proxy locking.
//
//
//
// The default locking schemes in SQLite use byte-range locks on the
// database file to coordinate safe, concurrent access by multiple readers
// and writers [http://sqlite.org/lockingv3.html].  The five file locking
// states (UNLOCKED, PENDING, SHARED, RESERVED, EXCLUSIVE) are implemented
// as POSIX read & write locks over fixed set of locations (via fsctl),
// on AFP and SMB only exclusive byte-range locks are available via fsctl
// with _IOWR('z', 23, struct ByteRangeLockPB2) to track the same 5 states.
// To simulate a F_RDLCK on the shared range, on AFP a randomly selected
// address in the shared range is taken for a SHARED lock, the entire
// shared range is taken for an EXCLUSIVE lock):
//
//      PENDING_BYTE        0x40000000
//      RESERVED_BYTE       0x40000001
//      SHARED_RANGE        0x40000002 -> 0x40000200
//
// This works well on the local file system, but shows a nearly 100x
// slowdown in read performance on AFP because the AFP client disables
// the read cache when byte-range locks are present.  Enabling the read
// cache exposes a cache coherency problem that is present on all OS X
// supported network file systems.  NFS and AFP both observe the
// close-to-open semantics for ensuring cache coherency
// [http://nfs.sourceforge.net/#faq_a8], which does not effectively
// address the requirements for concurrent database access by multiple
// readers and writers
// [http://www.nabble.com/SQLite-on-NFS-cache-coherency-td15655701.html].
//
// To address the performance and cache coherency issues, proxy file locking
// changes the way database access is controlled by limiting access to a
// single host at a time and moving file locks off of the database file
// and onto a proxy file on the local file system.
//
//
// Using proxy locks
// -----------------
//
// C APIs
//
//  sqlite3_file_control(db, dbname, SQLITE_FCNTL_SET_LOCKPROXYFILE,
//                       <proxy_path> | ":auto:");
//  sqlite3_file_control(db, dbname, SQLITE_FCNTL_GET_LOCKPROXYFILE,
//                       &<proxy_path>);
//
//
// SQL pragmas
//
//  PRAGMA [database.]lock_proxy_file=<proxy_path> | :auto:
//  PRAGMA [database.]lock_proxy_file
//
// Specifying ":auto:" means that if there is a conch file with a matching
// host ID in it, the proxy path in the conch file will be used, otherwise
// a proxy path based on the user's temp dir
// (via confstr(_CS_DARWIN_USER_TEMP_DIR,...)) will be used and the
// actual proxy file name is generated from the name and path of the
// database file.  For example:
//
//       For database path "/Users/me/foo.db"
//       The lock path will be "<tmpdir>/sqliteplocks/_Users_me_foo.db:auto:")
//
// Once a lock proxy is configured for a database connection, it can not
// be removed, however it may be switched to a different proxy path via
// the above APIs (assuming the conch file is not being held by another
// connection or process).
//
//
// How proxy locking works
// -----------------------
//
// Proxy file locking relies primarily on two new supporting files:
//
//   *  conch file to limit access to the database file to a single host
//      at a time
//
//   *  proxy file to act as a proxy for the advisory locks normally
//      taken on the database
//
// The conch file - to use a proxy file, sqlite must first "hold the conch"
// by taking an sqlite-style shared lock on the conch file, reading the
// contents and comparing the host's unique host ID (see below) and lock
// proxy path against the values stored in the conch.  The conch file is
// stored in the same directory as the database file and the file name
// is patterned after the database file name as ".<databasename>-conch".
// If the conch file does not exist, or its contents do not match the
// host ID and/or proxy path, then the lock is escalated to an exclusive
// lock and the conch file contents is updated with the host ID and proxy
// path and the lock is downgraded to a shared lock again.  If the conch
// is held by another process (with a shared lock), the exclusive lock
// will fail and SQLITE_BUSY is returned.
//
// The proxy file - a single-byte file used for all advisory file locks
// normally taken on the database file.   This allows for safe sharing
// of the database file for multiple readers and writers on the same
// host (the conch ensures that they all use the same local lock file).
//
// Requesting the lock proxy does not immediately take the conch, it is
// only taken when the first request to lock database file is made.
// This matches the semantics of the traditional locking behavior, where
// opening a connection to a database file does not take a lock on it.
// The shared lock and an open file descriptor are maintained until
// the connection to the database is closed.
//
// The proxy file and the lock file are never deleted so they only need
// to be created the first time they are used.
//
// Configuration options
// ---------------------
//
//  SQLITE_PREFER_PROXY_LOCKING
//
//       Database files accessed on non-local file systems are
//       automatically configured for proxy locking, lock files are
//       named automatically using the same logic as
//       PRAGMA lock_proxy_file=":auto:"
//
//  SQLITE_PROXY_DEBUG
//
//       Enables the logging of error messages during host id file
//       retrieval and creation
//
//  LOCKPROXYDIR
//
//       Overrides the default directory used for lock proxy files that
//       are named automatically via the ":auto:" setting
//
//  SQLITE_DEFAULT_PROXYDIR_PERMISSIONS
//
//       Permissions to use when creating a directory for storing the
//       lock proxy files, only used when LOCKPROXYDIR is not set.
//
//
// As mentioned above, when compiled with SQLITE_PREFER_PROXY_LOCKING,
// setting the environment variable SQLITE_FORCE_PROXY_LOCKING to 1 will
// force proxy locking to be used for every database file opened, and 0
// will force automatic proxy locking to be disabled for all database
// files (explicitly calling the SQLITE_FCNTL_SET_LOCKPROXYFILE pragma or
// sqlite_file_control API is not affected by SQLITE_FORCE_PROXY_LOCKING).

// Proxy locking is only available on MacOSX
//
// The proxy locking style is intended for use with AFP filesystems.
// And since AFP is only supported on MacOSX, the proxy locking is also
// restricted to MacOSX.
//

// page.  1 means allocate a new page if space is easily available.  2
// means to try really hard to allocate a new page.
//
// For a non-purgeable cache (a cache used as the storage for an in-memory
// database) there is really no difference between createFlag 1 and 2.  So
// the calling function (pcache.c) will never have a createFlag of 1 on
// a non-purgeable cache.
//
// There are three different approaches to obtaining space for a page,
// depending on the value of parameter createFlag (which may be 0, 1 or 2).
//
//   1. Regardless of the value of createFlag, the cache is searched for a
//      copy of the requested page. If one is found, it is returned.
//
//   2. If createFlag==0 and the page is not already in the cache, NULL is
//      returned.
//
//   3. If createFlag is 1, and the page is not already in the cache, then
//      return NULL (do not allocate a new page) if any of the following
//      conditions are true:
//
//       (a) the number of pages pinned by the cache is greater than
//           PCache1.nMax, or
//
//       (b) the number of pages pinned by the cache is greater than
//           the sum of nMax for all purgeable caches, less the sum of
//           nMin for all other purgeable caches, or
//
//   4. If none of the first three conditions apply and the cache is marked
//      as purgeable, and if one of the following is true:
//
//       (a) The number of pages allocated for the cache is already
//           PCache1.nMax, or
//
//       (b) The number of pages allocated for all purgeable caches is
//           already equal to or greater than the sum of nMax for all
//           purgeable caches,
//
//       (c) The system is under memory pressure and wants to avoid
//           unnecessary pages cache entry allocations
//
//      then attempt to recycle a page from the LRU list. If it is the right
//      size, return the recycled buffer. Otherwise, free the buffer and
//      proceed to step 5.

//
// This module implements an object we call a "RowSet".
//
// The RowSet object is a collection of rowids.  Rowids
// are inserted into the RowSet in an arbitrary order.  Inserts
// can be intermixed with tests to see if a given rowid has been
// previously inserted into the RowSet.
//
// After all inserts are finished, it is possible to extract the
// elements of the RowSet in sorted order.  Once this extraction
// process has started, no new elements may be inserted.
//
// Hence, the primitive operations for a RowSet are:
//
//    CREATE
//    INSERT
//    TEST
//    SMALLEST
//    DESTROY
//
// The CREATE and DESTROY primitives are the constructor and destructor,
// obviously.  The INSERT primitive adds a new element to the RowSet.
// TEST checks to see if an element is already in the RowSet.  SMALLEST
// extracts the least value from the RowSet.
//
// The INSERT primitive might allocate additional memory.  Memory is
// allocated in chunks so most INSERTs do no allocation.  There is an
// upper bound on the size of allocated memory.  No memory is freed
// until DESTROY.
//
// The TEST primitive includes a "batch" number.  The TEST primitive
// will only see elements that were inserted before the last change
// in the batch number.  In other words, if an INSERT occurs between
// two TESTs where the TESTs have the same batch nubmer, then the
// value added by the INSERT will not be visible to the second TEST.
// The initial batch number is zero, so if the very first TEST contains
// a non-zero batch number, it will see all prior INSERTs.
//
// No INSERTs may occurs after a SMALLEST.  An assertion will fail if
// that is attempted.
//
// The cost of an INSERT is roughly constant.  (Sometimes new memory
// has to be allocated on an INSERT.)  The cost of a TEST with a new
// batch number is O(NlogN) where N is the number of elements in the RowSet.
// The cost of a TEST using the same batch number is O(logN).  The cost
// of the first SMALLEST is O(NlogN).  Second and subsequent SMALLEST
// primitives are constant time.  The cost of DESTROY is O(N).
//
// TEST and SMALLEST may not be used by the same RowSet.  This used to
// be possible, but the feature was not used, so it was removed in order
// to simplify the code.

// ****************** NOTES ON THE DESIGN OF THE PAGER ************************
//
//
// This comment block describes invariants that hold when using a rollback
// journal.  These invariants do not apply for journal_mode=WAL,
// journal_mode=MEMORY, or journal_mode=OFF.
//
// Within this comment block, a page is deemed to have been synced
// automatically as soon as it is written when PRAGMA synchronous=OFF.
// Otherwise, the page is not synced until the xSync method of the VFS
// is called successfully on the file containing the page.
//
// Definition:  A page of the database file is said to be "overwriteable" if
// one or more of the following are true about the page:
//
//     (a)  The original content of the page as it was at the beginning of
//          the transaction has been written into the rollback journal and
//          synced.
//
//     (b)  The page was a freelist leaf page at the start of the transaction.
//
//     (c)  The page number is greater than the largest page that existed in
//          the database file at the start of the transaction.
//
// (1) A page of the database file is never overwritten unless one of the
//     following are true:
//
//     (a) The page and all other pages on the same sector are overwriteable.
//
//     (b) The atomic page write optimization is enabled, and the entire
//         transaction other than the update of the transaction sequence
//         number consists of a single page change.
//
// (2) The content of a page written into the rollback journal exactly matches
//     both the content in the database when the rollback journal was written
//     and the content in the database at the beginning of the current

//
// (7) At any time, if any subset, including the empty set and the total set,

//     equivalent to the database file at the beginning of the transaction.
//
// (8) When a transaction is rolled back, the xTruncate method of the VFS
//     is called to restore the database file to the same size it was at

//     method is a no-op, but that does not change the fact the SQLite will

//
//  OPEN:
//
//    The pager starts up in this state. Nothing is guaranteed in this
//    state - the file may or may not be locked and the database size is
//    unknown. The database may not be read or written.
//
//    * No read or write transaction is active.
//    * Any lock, or no lock at all, may be held on the database file.
//    * The dbSize, dbOrigSize and dbFileSize variables may not be trusted.
//
//  READER:
//
//    In this state all the requirements for reading the database in
//    rollback (non-WAL) mode are met. Unless the pager is (or recently
//    was) in exclusive-locking mode, a user-level read transaction is
//    open. The database size is known in this state.
//
//    A connection running with locking_mode=normal enters this state when
//    it opens a read-transaction on the database and returns to state
//    OPEN after the read-transaction is completed. However a connection
//    running in locking_mode=exclusive (including temp databases) remains in
//    this state even after the read-transaction is closed. The only way
//    a locking_mode=exclusive connection can transition from READER to OPEN
//    is via the ERROR state (see below).
//
//    * A read transaction may be active (but a write-transaction cannot).
//    * A SHARED or greater lock is held on the database file.
//    * The dbSize variable may be trusted (even if a user-level read
//      transaction is not active). The dbOrigSize and dbFileSize variables
//      may not be trusted at this point.
//    * If the database is a WAL database, then the WAL connection is open.
//    * Even if a read-transaction is not open, it is guaranteed that
//      there is no hot-journal in the file-system.
//
//  WRITER_LOCKED:
//
//    The pager moves to this state from READER when a write-transaction
//    is first opened on the database. In WRITER_LOCKED state, all locks
//    required to start a write-transaction are held, but no actual
//    modifications to the cache or database have taken place.
//
//    In rollback mode, a RESERVED or (if the transaction was opened with
//    BEGIN EXCLUSIVE) EXCLUSIVE lock is obtained on the database file when
//    moving to this state, but the journal file is not written to or opened
//    to in this state. If the transaction is committed or rolled back while
//    in WRITER_LOCKED state, all that is required is to unlock the database
//    file.
//
//    IN WAL mode, WalBeginWriteTransaction() is called to lock the log file.
//    If the connection is running with locking_mode=exclusive, an attempt
//    is made to obtain an EXCLUSIVE lock on the database file.
//
//    * A write transaction is active.
//    * If the connection is open in rollback-mode, a RESERVED or greater
//      lock is held on the database file.
//    * If the connection is open in WAL-mode, a WAL write transaction
//      is open (i.e. sqlite3WalBeginWriteTransaction() has been successfully
//      called).
//    * The dbSize, dbOrigSize and dbFileSize variables are all valid.
//    * The contents of the pager cache have not been modified.
//    * The journal file may or may not be open.
//    * Nothing (not even the first header) has been written to the journal.
//
//  WRITER_CACHEMOD:
//
//    A pager moves from WRITER_LOCKED state to this state when a page is
//    first modified by the upper layer. In rollback mode the journal file
//    is opened (if it is not already open) and a header written to the
//    start of it. The database file on disk has not been modified.
//
//    * A write transaction is active.
//    * A RESERVED or greater lock is held on the database file.
//    * The journal file is open and the first header has been written
//      to it, but the header has not been synced to disk.
//    * The contents of the page cache have been modified.
//
//  WRITER_DBMOD:
//
//    The pager transitions from WRITER_CACHEMOD into WRITER_DBMOD state
//    when it modifies the contents of the database file. WAL connections
//    never enter this state (since they do not modify the database file,
//    just the log file).
//
//    * A write transaction is active.
//    * An EXCLUSIVE or greater lock is held on the database file.
//    * The journal file is open and the first header has been written
//      and synced to disk.
//    * The contents of the page cache have been modified (and possibly
//      written to disk).
//
//  WRITER_FINISHED:
//
//    It is not possible for a WAL connection to enter this state.
//
//    A rollback-mode pager changes to WRITER_FINISHED state from WRITER_DBMOD
//    state after the entire transaction has been successfully written into the
//    database file. In this state the transaction may be committed simply
//    by finalizing the journal file. Once in WRITER_FINISHED state, it is
//    not possible to modify the database further. At this point, the upper
//    layer must either commit or rollback the transaction.
//
//    * A write transaction is active.
//    * An EXCLUSIVE or greater lock is held on the database file.
//    * All writing and syncing of journal and database data has finished.
//      If no error occurred, all that remains is to finalize the journal to
//      commit the transaction. If an error did occur, the caller will need
//      to rollback the transaction.
//
//  ERROR:
//
//    The ERROR state is entered when an IO or disk-full error (including
//    SQLITE_IOERR_NOMEM) occurs at a point in the code that makes it
//    difficult to be sure that the in-memory pager state (cache contents,
//    db size etc.) are consistent with the contents of the file-system.
//
//    Temporary pager files may enter the ERROR state, but in-memory pagers
//    cannot.
//
//    For example, if an IO error occurs while performing a rollback,
//    the contents of the page-cache may be left in an inconsistent state.
//    At this point it would be dangerous to change back to READER state
//    (as usually happens after a rollback). Any subsequent readers might
//    report database corruption (due to the inconsistent cache), and if
//    they upgrade to writers, they may inadvertently corrupt the database
//    file. To avoid this hazard, the pager switches into the ERROR state
//    instead of READER following such an error.
//
//    Once it has entered the ERROR state, any attempt to use the pager
//    to read or write data returns an error. Eventually, once all
//    outstanding transactions have been abandoned, the pager is able to
//    transition back to OPEN state, discarding the contents of the
//    page-cache and any other in-memory state at the same time. Everything
//    is reloaded from disk (and, if necessary, hot-journal rollback peformed)
//    when a read-transaction is next opened on the pager (transitioning
//    the pager into READER state). At that point the system has recovered
//    from the error.
//
//    Specifically, the pager jumps into the ERROR state if:
//
//      1. An error occurs while attempting a rollback. This happens in
//         function sqlite3PagerRollback().
//
//      2. An error occurs while attempting to finalize a journal file
//         following a commit in function sqlite3PagerCommitPhaseTwo().
//
//      3. An error occurs while attempting to write to the journal or
//         database file in function pagerStress() in order to free up
//         memory.
//
//    In other cases, the error is returned to the b-tree layer. The b-tree
//    layer then attempts a rollback operation. If the error condition
//    persists, the pager enters the ERROR state via condition (1) above.
//
//    Condition (3) is necessary because it can be triggered by a read-only
//    statement executed within a transaction. In this case, if the error
//    code were simply returned to the user, the b-tree layer would not
//    automatically attempt a rollback, as it assumes that an error in a
//    read-only statement cannot leave the pager in an internally inconsistent
//    state.
//
//    * The Pager.errCode variable is set to something other than SQLITE_OK.
//    * There are one or more outstanding references to pages (after the
//      last reference is dropped the pager should move back to OPEN state).
//    * The pager is not an in-memory pager.
//
//
// Notes:
//
//   * A pager is never in WRITER_DBMOD or WRITER_FINISHED state if the
//     connection is open in WAL mode. A WAL connection is always in one
//     of the first four states.
//
//   * Normally, a connection open in exclusive mode is never in PAGER_OPEN
//     state. There are two exceptions: immediately after exclusive-mode has
//     been turned on (and before any read or write transactions are
//     executed), and when the pager is leaving the "error state".
//
//   * See also: assert_pager_state().

// The Pager.eLock variable is almost always set to one of the
// following locking-states, according to the lock currently held on
// the database file: NO_LOCK, SHARED_LOCK, RESERVED_LOCK or EXCLUSIVE_LOCK.
// This variable is kept up to date as locks are taken and released by
// the pagerLockDb() and pagerUnlockDb() wrappers.
//
// If the VFS xLock() or xUnlock() returns an error other than SQLITE_BUSY
// (i.e. one of the SQLITE_IOERR subtypes), it is not clear whether or not
// the operation was successful. In these circumstances pagerLockDb() and
// pagerUnlockDb() take a conservative approach - eLock is always updated
// when unlocking the file, and only updated when locking the file if the
// VFS call is successful. This way, the Pager.eLock variable may be set
// to a less exclusive (lower) value than the lock that is actually held
// at the system level, but it is never set to a more exclusive value.
//
// This is usually safe. If an xUnlock fails or appears to fail, there may
// be a few redundant xLock() calls or a lock may be held for longer than
// required, but nothing really goes wrong.
//
// The exception is when the database file is unlocked as the pager moves
// from ERROR to OPEN state. At this point there may be a hot-journal file
// in the file-system that needs to be rolled back (as part of an OPEN->SHARED
// transition, by the same pager or any other). If the call to xUnlock()
// fails at this point and the pager is left holding an EXCLUSIVE lock, this
// can confuse the call to xCheckReservedLock() call made later as part
// of hot-journal detection.
//
// xCheckReservedLock() is defined as returning true "if there is a RESERVED
// lock held by this process or any others". So xCheckReservedLock may
// return true because the caller itself is holding an EXCLUSIVE lock (but
// doesn't know it because of a previous error in xUnlock). If this happens
// a hot-journal may be mistaken for a journal being created by an active
// transaction in another process, causing SQLite to read from the database
// without rolling it back.
//
// To work around this, if a call to xUnlock() fails when unlocking the
// database in the ERROR state, Pager.eLock is set to UNKNOWN_LOCK. It
// is only changed back to a real locking state after a successful call
// to xLock(EXCLUSIVE). Also, the code to do the OPEN->SHARED state transition
// omits the check for a hot-journal if Pager.eLock is set to UNKNOWN_LOCK
// lock. Instead, it assumes a hot-journal exists and obtains an EXCLUSIVE
// lock on the database file before attempting to roll it back. See function
// PagerSharedLock() for more detail.
//
// Pager.eLock may only be set to UNKNOWN_LOCK when the pager is in
// PAGER_OPEN state.

// The maximum allowed sector size. 64KiB. If the xSectorsize() method
// returns a value larger than this, then MAX_SECTOR_SIZE is used instead.
// This could conceivably cause corruption following a power failure on
// such a system. This is currently an undocumented limit.

// An instance of the following structure is allocated for each active
// savepoint and statement transaction in the system. All such structures
// are stored in the Pager.aSavepoint[] array, which is allocated and
// resized using sqlite3Realloc().
//
// When a savepoint is created, the PagerSavepoint.iHdrOffset field is
// set to 0. If a journal-header is written into the main journal while
// the savepoint is active, then iHdrOffset is set to the byte offset
// immediately following the last journal record written into the main
// journal before the journal-header. This is required during savepoint
// rollback (see pagerPlaybackSavepoint()).

// ****************** NOTES ON THE DESIGN OF THE PAGER ************************
//
//
// This comment block describes invariants that hold when using a rollback
// journal.  These invariants do not apply for journal_mode=WAL,
// journal_mode=MEMORY, or journal_mode=OFF.
//
// Within this comment block, a page is deemed to have been synced
// automatically as soon as it is written when PRAGMA synchronous=OFF.
// Otherwise, the page is not synced until the xSync method of the VFS
// is called successfully on the file containing the page.
//
// Definition:  A page of the database file is said to be "overwriteable" if
// one or more of the following are true about the page:
//
//     (a)  The original content of the page as it was at the beginning of
//          the transaction has been written into the rollback journal and
//          synced.
//
//     (b)  The page was a freelist leaf page at the start of the transaction.
//
//     (c)  The page number is greater than the largest page that existed in
//          the database file at the start of the transaction.
//
// (1) A page of the database file is never overwritten unless one of the
//     following are true:
//
//     (a) The page and all other pages on the same sector are overwriteable.
//
//     (b) The atomic page write optimization is enabled, and the entire
//         transaction other than the update of the transaction sequence
//         number consists of a single page change.
//
// (2) The content of a page written into the rollback journal exactly matches
//     both the content in the database when the rollback journal was written
//     and the content in the database at the beginning of the current
//     transaction.
//
// (3) Writes to the database file are an integer multiple of the page size
//     in length and are aligned on a page boundary.
//
// (4) Reads from the database file are either aligned on a page boundary and
//     an integer multiple of the page size in length or are taken from the
//     first 100 bytes of the database file.
//
// (5) All writes to the database file are synced prior to the rollback journal
//     being deleted, truncated, or zeroed.
//
// (6) If a super-journal file is used, then all writes to the database file
//     are synced prior to the super-journal being deleted.
//
// Definition: Two databases (or the same database at two points it time)
// are said to be "logically equivalent" if they give the same answer to
// all queries.  Note in particular the content of freelist leaf
// pages can be changed arbitrarily without affecting the logical equivalence
// of the database.
//
// (7) At any time, if any subset, including the empty set and the total set,
//     of the unsynced changes to a rollback journal are removed and the
//     journal is rolled back, the resulting database file will be logically
//     equivalent to the database file at the beginning of the transaction.
//
// (8) When a transaction is rolled back, the xTruncate method of the VFS
//     is called to restore the database file to the same size it was at
//     the beginning of the transaction.  (In some VFSes, the xTruncate
//     method is a no-op, but that does not change the fact the SQLite will
//     invoke it.)
//
// (9) Whenever the database file is modified, at least one bit in the range
//     of bytes from 24 through 39 inclusive will be changed prior to releasing
//     the EXCLUSIVE lock, thus signaling other connections on the same
//     database to flush their caches.
//
// (10) The pattern of bits in bytes 24 through 39 shall not repeat in less
//      than one billion transactions.
//
// (11) A database file is well-formed at the beginning and at the conclusion
//      of every transaction.
//
// (12) An EXCLUSIVE lock is held on the database file when writing to
//      the database file.

//    open. The database size is known in this state.
//
//    A connection running with locking_mode=normal enters this state when
//    it opens a read-transaction on the database and returns to state
//    OPEN after the read-transaction is completed. However a connection
//    running in locking_mode=exclusive (including temp databases) remains in
//    this state even after the read-transaction is closed. The only way
//    a locking_mode=exclusive connection can transition from READER to OPEN
//    is via the ERROR state (see below).
//
//    * A read transaction may be active (but a write-transaction cannot).
//    * A SHARED or greater lock is held on the database file.
//    * The dbSize variable may be trusted (even if a user-level read
//      transaction is not active). The dbOrigSize and dbFileSize variables
//      may not be trusted at this point.
//    * If the database is a WAL database, then the WAL connection is open.
//    * Even if a read-transaction is not open, it is guaranteed that
//      there is no hot-journal in the file-system.
//
//  WRITER_LOCKED:
//
//    The pager moves to this state from READER when a write-transaction
//    is first opened on the database. In WRITER_LOCKED state, all locks
//    required to start a write-transaction are held, but no actual
//    modifications to the cache or database have taken place.
//
//    In rollback mode, a RESERVED or (if the transaction was opened with
//    BEGIN EXCLUSIVE) EXCLUSIVE lock is obtained on the database file when
//    moving to this state, but the journal file is not written to or opened
//    to in this state. If the transaction is committed or rolled back while
//    in WRITER_LOCKED state, all that is required is to unlock the database
//    file.
//
//    IN WAL mode, WalBeginWriteTransaction() is called to lock the log file.
//    If the connection is running with locking_mode=exclusive, an attempt
//    is made to obtain an EXCLUSIVE lock on the database file.
//
//    * A write transaction is active.
//    * If the connection is open in rollback-mode, a RESERVED or greater
//      lock is held on the database file.
//    * If the connection is open in WAL-mode, a WAL write transaction
//      is open (i.e. sqlite3WalBeginWriteTransaction() has been successfully
//      called).
//    * The dbSize, dbOrigSize and dbFileSize variables are all valid.
//    * The contents of the pager cache have not been modified.
//    * The journal file may or may not be open.
//    * Nothing (not even the first header) has been written to the journal.
//
//  WRITER_CACHEMOD:
//
//    A pager moves from WRITER_LOCKED state to this state when a page is
//    first modified by the upper layer. In rollback mode the journal file
//    is opened (if it is not already open) and a header written to the
//    start of it. The database file on disk has not been modified.
//
//    * A write transaction is active.
//    * A RESERVED or greater lock is held on the database file.
//    * The journal file is open and the first header has been written
//      to it, but the header has not been synced to disk.
//    * The contents of the page cache have been modified.
//
//  WRITER_DBMOD:
//
//    The pager transitions from WRITER_CACHEMOD into WRITER_DBMOD state
//    when it modifies the contents of the database file. WAL connections
//    never enter this state (since they do not modify the database file,
//    just the log file).
//
//    * A write transaction is active.
//    * An EXCLUSIVE or greater lock is held on the database file.
//    * The journal file is open and the first header has been written
//      and synced to disk.
//    * The contents of the page cache have been modified (and possibly
//      written to disk).
//
//  WRITER_FINISHED:
//
//    It is not possible for a WAL connection to enter this state.
//
//    A rollback-mode pager changes to WRITER_FINISHED state from WRITER_DBMOD
//    state after the entire transaction has been successfully written into the
//    database file. In this state the transaction may be committed simply
//    by finalizing the journal file. Once in WRITER_FINISHED state, it is
//    not possible to modify the database further. At this point, the upper
//    layer must either commit or rollback the transaction.
//
//    * A write transaction is active.
//    * An EXCLUSIVE or greater lock is held on the database file.
//    * All writing and syncing of journal and database data has finished.
//      If no error occurred, all that remains is to finalize the journal to
//      commit the transaction. If an error did occur, the caller will need
//      to rollback the transaction.
//
//  ERROR:
//
//    The ERROR state is entered when an IO or disk-full error (including
//    SQLITE_IOERR_NOMEM) occurs at a point in the code that makes it
//    difficult to be sure that the in-memory pager state (cache contents,
//    db size etc.) are consistent with the contents of the file-system.
//
//    Temporary pager files may enter the ERROR state, but in-memory pagers
//    cannot.
//
//    For example, if an IO error occurs while performing a rollback,
//    the contents of the page-cache may be left in an inconsistent state.
//    At this point it would be dangerous to change back to READER state
//    (as usually happens after a rollback). Any subsequent readers might
//    report database corruption (due to the inconsistent cache), and if
//    they upgrade to writers, they may inadvertently corrupt the database
//    file. To avoid this hazard, the pager switches into the ERROR state
//    instead of READER following such an error.
//
//    Once it has entered the ERROR state, any attempt to use the pager
//    to read or write data returns an error. Eventually, once all
//    outstanding transactions have been abandoned, the pager is able to
//    transition back to OPEN state, discarding the contents of the
//    page-cache and any other in-memory state at the same time. Everything
//    is reloaded from disk (and, if necessary, hot-journal rollback peformed)
//    when a read-transaction is next opened on the pager (transitioning
//    the pager into READER state). At that point the system has recovered
//    from the error.
//
//    Specifically, the pager jumps into the ERROR state if:
//
//      1. An error occurs while attempting a rollback. This happens in
//         function sqlite3PagerRollback().
//
//      2. An error occurs while attempting to finalize a journal file
//         following a commit in function sqlite3PagerCommitPhaseTwo().
//
//      3. An error occurs while attempting to write to the journal or
//         database file in function pagerStress() in order to free up
//         memory.
//
//    In other cases, the error is returned to the b-tree layer. The b-tree
//    layer then attempts a rollback operation. If the error condition
//    persists, the pager enters the ERROR state via condition (1) above.
//
//    Condition (3) is necessary because it can be triggered by a read-only
//    statement executed within a transaction. In this case, if the error
//    code were simply returned to the user, the b-tree layer would not
//    automatically attempt a rollback, as it assumes that an error in a
//    read-only statement cannot leave the pager in an internally inconsistent
//    state.
//
//    * The Pager.errCode variable is set to something other than SQLITE_OK.
//    * There are one or more outstanding references to pages (after the
//      last reference is dropped the pager should move back to OPEN state).
//    * The pager is not an in-memory pager.
//
//
// Notes:
//
//   * A pager is never in WRITER_DBMOD or WRITER_FINISHED state if the
//     connection is open in WAL mode. A WAL connection is always in one
//     of the first four states.
//
//   * Normally, a connection open in exclusive mode is never in PAGER_OPEN
//     state. There are two exceptions: immediately after exclusive-mode has
//     been turned on (and before any read or write transactions are
//     executed), and when the pager is leaving the "error state".
//
//   * See also: assert_pager_state().

// The Pager.eLock variable is almost always set to one of the
// following locking-states, according to the lock currently held on
// the database file: NO_LOCK, SHARED_LOCK, RESERVED_LOCK or EXCLUSIVE_LOCK.
// This variable is kept up to date as locks are taken and released by
// the pagerLockDb() and pagerUnlockDb() wrappers.
//
// If the VFS xLock() or xUnlock() returns an error other than SQLITE_BUSY
// (i.e. one of the SQLITE_IOERR subtypes), it is not clear whether or not
// the operation was successful. In these circumstances pagerLockDb() and
// pagerUnlockDb() take a conservative approach - eLock is always updated
// when unlocking the file, and only updated when locking the file if the
// VFS call is successful. This way, the Pager.eLock variable may be set
// to a less exclusive (lower) value than the lock that is actually held
// at the system level, but it is never set to a more exclusive value.
//
// This is usually safe. If an xUnlock fails or appears to fail, there may
// be a few redundant xLock() calls or a lock may be held for longer than
// required, but nothing really goes wrong.
//
// The exception is when the database file is unlocked as the pager moves
// from ERROR to OPEN state. At this point there may be a hot-journal file
// in the file-system that needs to be rolled back (as part of an OPEN->SHARED
// transition, by the same pager or any other). If the call to xUnlock()
// fails at this point and the pager is left holding an EXCLUSIVE lock, this
// can confuse the call to xCheckReservedLock() call made later as part
// of hot-journal detection.
//
// xCheckReservedLock() is defined as returning true "if there is a RESERVED
// lock held by this process or any others". So xCheckReservedLock may
// return true because the caller itself is holding an EXCLUSIVE lock (but
// doesn't know it because of a previous error in xUnlock). If this happens
// a hot-journal may be mistaken for a journal being created by an active
// transaction in another process, causing SQLite to read from the database
// without rolling it back.
//
// To work around this, if a call to xUnlock() fails when unlocking the
// database in the ERROR state, Pager.eLock is set to UNKNOWN_LOCK. It
// is only changed back to a real locking state after a successful call
// to xLock(EXCLUSIVE). Also, the code to do the OPEN->SHARED state transition
// omits the check for a hot-journal if Pager.eLock is set to UNKNOWN_LOCK
// lock. Instead, it assumes a hot-journal exists and obtains an EXCLUSIVE
// lock on the database file before attempting to roll it back. See function
// PagerSharedLock() for more detail.
//
// Pager.eLock may only be set to UNKNOWN_LOCK when the pager is in
// PAGER_OPEN state.

// The maximum allowed sector size. 64KiB. If the xSectorsize() method
// returns a value larger than this, then MAX_SECTOR_SIZE is used instead.
// This could conceivably cause corruption following a power failure on
// such a system. This is currently an undocumented limit.

// An instance of the following structure is allocated for each active
// savepoint and statement transaction in the system. All such structures
// are stored in the Pager.aSavepoint[] array, which is allocated and
// resized using sqlite3Realloc().
//
// When a savepoint is created, the PagerSavepoint.iHdrOffset field is
// set to 0. If a journal-header is written into the main journal while
// the savepoint is active, then iHdrOffset is set to the byte offset
// immediately following the last journal record written into the main
// journal before the journal-header. This is required during savepoint
// rollback (see pagerPlaybackSavepoint()).

// This routine ends a transaction. A transaction is usually ended by
// either a COMMIT or a ROLLBACK operation. This routine may be called
// after rollback of a hot-journal, or if an error occurs while opening
// the journal file or writing the very first journal-header of a
// database transaction.
//
// This routine is never called in PAGER_ERROR state. If it is called
// in PAGER_NONE or PAGER_SHARED state and the lock held is less
// exclusive than a RESERVED lock, it is a no-op.
//
// Otherwise, any active savepoints are released.
//
// If the journal file is open, then it is "finalized". Once a journal
// file has been finalized it is not possible to use it to roll back a
// transaction. Nor will it be considered to be a hot-journal by this
// or any other database connection. Exactly how a journal is finalized
// depends on whether or not the pager is running in exclusive mode and
// the current journal-mode (Pager.journalMode value), as follows:
//
//   journalMode==MEMORY
//     Journal file descriptor is simply closed. This destroys an
//     in-memory journal.
//
//   journalMode==TRUNCATE
//     Journal file is truncated to zero bytes in size.
//
//   journalMode==PERSIST
//     The first 28 bytes of the journal file are zeroed. This invalidates
//     the first journal header in the file, and hence the entire journal
//     file. An invalid journal file cannot be rolled back.
//
//   journalMode==DELETE
//     The journal file is closed and deleted using sqlite3OsDelete().
//
//     If the pager is running in exclusive mode, this method of finalizing
//     the journal file is never used. Instead, if the journalMode is
//     DELETE and the pager is in exclusive mode, the method described under
//     journalMode==PERSIST is used instead.
//
// After the journal is finalized, the pager moves to PAGER_READER state.
// If running in non-exclusive rollback mode, the lock on the file is
// downgraded to a SHARED_LOCK.
//
// SQLITE_OK is returned if no error occurs. If an error occurs during
// any of the IO operations to finalize the journal file or unlock the
// database then the IO error code is returned to the user. If the
// operation to finalize the journal file fails, then the code still
// tries to unlock the database file if not in exclusive mode. If the
// unlock operation fails as well, then the first error code related
// to the first error encountered (the journal finalization one) is
// returned.

//       database to during a rollback.
//  (5)  4 byte big-endian integer which is the sector size.  The header
//       is this many bytes in size.
//  (6)  4 byte big-endian integer which is the page size.
//  (7)  zero padding out to the next sector size.

//
// When we speak of the journal header, we mean the first 7 items above.

// valid page entries in the journal.  In most cases, you can compute the
// value of nRec from the size of the journal file.  But if a power
// failure occurred while the journal was being written, it could be the
// case that the size of the journal file had already been increased but
// the extra entries had not yet made it safely to disk.  In such a case,
// the value of nRec computed from the file size would be too large.  For
// that reason, we always use the nRec value in the header.
//
// If the nRec value is 0xffffffff it means that nRec should be computed
// from the file size.  This value is used when the user selects the
// no-sync option for the journal.  A power failure could lead to corruption
// in this case.  But for things like temporary table (which will be
// deleted when the power is restored) we don't care.
//
// If the file opened as the journal file is not a well-formed
// journal file then all pages up to the first corrupted page are rolled
// back (or no pages if the journal header is corrupted). The journal file

// The "level" in pgFlags & PAGER_SYNCHRONOUS_MASK sets the robustness
// of the database to damage due to OS crashes or power failures by
// changing the number of syncs()s when writing the journals.
// There are four levels:
//
//    OFF       sqlite3OsSync() is never called.  This is the default
//              for temporary and transient files.
//
//    NORMAL    The journal is synced once before writes begin on the
//              database.  This is normally adequate protection, but
//              it is theoretically possible, though very unlikely,
//              that an inopertune power failure could leave the journal
//              in a state which would cause damage to the database
//              when it is rolled back.
//
//    FULL      The journal is synced twice before writes begin on the
//              database (with some additional information - the nRec field
//              of the journal header - being written in between the two
//              syncs).  If we assume that writing a
//              single disk sector is atomic, then this mode provides
//              assurance that the journal will not be corrupted to the
//              point of causing damage to the database during rollback.
//
//    EXTRA     This is like FULL except that is also syncs the directory
//              that contains the rollback journal after the rollback
//              journal is unlinked.
//
// The above is for a rollback-journal mode.  For WAL mode, OFF continues
// to mean that no syncs ever occur.  NORMAL means that the WAL is synced
// prior to the start of checkpoint and that the database file is synced
// at the conclusion of the checkpoint if the entire content of the WAL
// was written back into the database.  But no sync operations occur for
// an ordinary commit in NORMAL mode with WAL.  FULL means that the WAL
// file is synced following each commit operation, in addition to the
// syncs associated with NORMAL.  There is no difference between FULL
// and EXTRA for WAL mode.
//
// Do not confuse synchronous=FULL with SQLITE_SYNC_FULL.  The
// SQLITE_SYNC_FULL macro means to use the MacOSX-style full-fsync
// using fcntl(F_FULLFSYNC).  SQLITE_SYNC_NORMAL means to do an
// ordinary fsync() call.  There is no difference between SQLITE_SYNC_FULL
// and SQLITE_SYNC_NORMAL on platforms other than MacOSX.  But the
// synchronous=FULL versus synchronous=NORMAL setting determines when
// the xSync primitive is called and is relevant to all platforms.
//

// and FULL=3.

	// The sqlite3_create_filename() interface and the databaseFilename() utility

	// specific formatting and order of the various filenames, so if the format
	// changes here, be sure to change it there as well.

//
//   a) When reading a free-list leaf page from the database, and
//
//   b) When a savepoint is being rolled back and we need to load
//      a new page into the cache to be filled with the data read
//      from the savepoint journal.

// If PAGER_GET_NOCONTENT is true, then the data returned is zeroed instead
// of being read from the database. Additionally, the bits corresponding
// to pgno in Pager.pInJournal (bitvec of pages already written to the
// journal file) and the PagerSavepoint.pInSavepoint bitvecs of any open
// savepoints are set. This means if the page is made writable at any
// point in the future, using a call to sqlite3PagerWrite(), its contents
// will not be journaled. This saves IO.
//
// The acquisition might fail for several reasons.  In all cases,
// an appropriate error code is returned and *ppPage is set to NULL.

// See also sqlite3PagerLookup().  Both this routine and Lookup() attempt
// to find a page in the in-memory cache first.  If the page is not already

// This file contains the implementation of a write-ahead log (WAL) used in
// "journal_mode=WAL" mode.
//
// WRITE-AHEAD LOG (WAL) FILE FORMAT
//
// A WAL file consists of a header followed by zero or more "frames".
// Each frame records the revised content of a single page from the
// database file.  All changes to the database are recorded by writing
// frames into the WAL.  Transactions commit when a frame is written that
// contains a commit marker.  A single WAL can and usually does record
// multiple transactions.  Periodically, the content of the WAL is
// transferred back into the database file in an operation called a
// "checkpoint".
//
// A single WAL file can be used multiple times.  In other words, the
// WAL can fill up with frames and then be checkpointed and then new
// frames can overwrite the old ones.  A WAL always grows from beginning
// toward the end.  Checksums and counters attached to each frame are
// used to determine which frames within the WAL are valid and which
// are leftovers from prior checkpoints.
//
// The WAL header is 32 bytes in size and consists of the following eight
// big-endian 32-bit unsigned integer values:
//
//     0: Magic number.  0x377f0682 or 0x377f0683
//     4: File format version.  Currently 3007000
//     8: Database page size.  Example: 1024
//    12: Checkpoint sequence number
//    16: Salt-1, random integer incremented with each checkpoint
//    20: Salt-2, a different random integer changing with each ckpt
//    24: Checksum-1 (first part of checksum for first 24 bytes of header).
//    28: Checksum-2 (second part of checksum for first 24 bytes of header).
//
// Immediately following the wal-header are zero or more frames. Each
// frame consists of a 24-byte frame-header followed by a <page-size> bytes
// of page data. The frame-header is six big-endian 32-bit unsigned
// integer values, as follows:
//
//     0: Page number.
//     4: For commit records, the size of the database image in pages
//        after the commit. For all other records, zero.
//     8: Salt-1 (copied from the header)
//    12: Salt-2 (copied from the header)
//    16: Checksum-1.
//    20: Checksum-2.
//
// A frame is considered valid if and only if the following conditions are
// true:
//
//    (1) The salt-1 and salt-2 values in the frame-header match
//        salt values in the wal-header
//
//    (2) The checksum values in the final 8 bytes of the frame-header
//        exactly match the checksum computed consecutively on the
//        WAL header and the first 8 bytes and the content of all frames
//        up to and including the current frame.
//
// The checksum is computed using 32-bit big-endian integers if the
// magic number in the first 4 bytes of the WAL is 0x377f0683 and it
// is computed using little-endian if the magic number is 0x377f0682.
// The checksum values are always stored in the frame header in a
// big-endian format regardless of which byte order is used to compute
// the checksum.  The checksum is computed by interpreting the input as
// an even number of unsigned 32-bit integers: x[0] through x[N].  The
// algorithm used for the checksum is as follows:
//
//   for i from 0 to n-1 step 2:
//     s0 += x[i] + s1;
//     s1 += x[i+1] + s0;
//   endfor
//
// Note that s0 and s1 are both weighted checksums using fibonacci weights
// in reverse order (the largest fibonacci weight occurs on the first element
// of the sequence being summed.)  The s1 value spans all 32-bit
// terms of the sequence whereas s0 omits the final term.
//
// On a checkpoint, the WAL is first VFS.xSync-ed, then valid content of the
// WAL is transferred into the database, then the database is VFS.xSync-ed.
// The VFS.xSync operations serve as write barriers - all writes launched
// before the xSync must complete before any write that launches after the
// xSync begins.
//
// After each checkpoint, the salt-1 value is incremented and the salt-2
// value is randomized.  This prevents old and new frames in the WAL from
// being considered valid at the same time and being checkpointing together
// following a crash.
//
// READER ALGORITHM
//
// To read a page from the database (call it page number P), a reader
// first checks the WAL to see if it contains page P.  If so, then the
// last valid instance of page P that is a followed by a commit frame
// or is a commit frame itself becomes the value read.  If the WAL
// contains no copies of page P that are valid and which are a commit
// frame or are followed by a commit frame, then page P is read from
// the database file.
//
// To start a read transaction, the reader records the index of the last
// valid frame in the WAL.  The reader uses this recorded "mxFrame" value
// for all subsequent read operations.  New transactions can be appended
// to the WAL, but as long as the reader uses its original mxFrame value
// and ignores the newly appended content, it will see a consistent snapshot
// of the database from a single point in time.  This technique allows
// multiple concurrent readers to view different versions of the database
// content simultaneously.
//
// The reader algorithm in the previous paragraphs works correctly, but
// because frames for page P can appear anywhere within the WAL, the
// reader has to scan the entire WAL looking for page P frames.  If the
// WAL is large (multiple megabytes is typical) that scan can be slow,
// and read performance suffers.  To overcome this problem, a separate
// data structure called the wal-index is maintained to expedite the
// search for frames of a particular page.
//
// WAL-INDEX FORMAT
//
// Conceptually, the wal-index is shared memory, though VFS implementations
// might choose to implement the wal-index using a mmapped file.  Because
// the wal-index is shared memory, SQLite does not support journal_mode=WAL
// on a network filesystem.  All users of the database must be able to
// share memory.
//
// In the default unix and windows implementation, the wal-index is a mmapped
// file whose name is the database name with a "-shm" suffix added.  For that
// reason, the wal-index is sometimes called the "shm" file.
//
// The wal-index is transient.  After a crash, the wal-index can (and should
// be) reconstructed from the original WAL file.  In fact, the VFS is required
// to either truncate or zero the header of the wal-index when the last
// connection to it closes.  Because the wal-index is transient, it can
// use an architecture-specific format; it does not have to be cross-platform.
// Hence, unlike the database and WAL file formats which store all values
// as big endian, the wal-index can store multi-byte values in the native
// byte order of the host computer.
//
// The purpose of the wal-index is to answer this question quickly:  Given
// a page number P and a maximum frame index M, return the index of the
// last frame in the wal before frame M for page P in the WAL, or return
// NULL if there are no frames for page P in the WAL prior to M.
//
// The wal-index consists of a header region, followed by an one or
// more index blocks.
//
// The wal-index header contains the total number of frames within the WAL
// in the mxFrame field.
//
// Each index block except for the first contains information on
// HASHTABLE_NPAGE frames. The first index block contains information on
// HASHTABLE_NPAGE_ONE frames. The values of HASHTABLE_NPAGE_ONE and
// HASHTABLE_NPAGE are selected so that together the wal-index header and
// first index block are the same size as all other index blocks in the
// wal-index.  The values are:
//
//   HASHTABLE_NPAGE      4096
//   HASHTABLE_NPAGE_ONE  4062
//
// Each index block contains two sections, a page-mapping that contains the
// database page number associated with each wal frame, and a hash-table
// that allows readers to query an index block for a specific page number.
// The page-mapping is an array of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE
// for the first index block) 32-bit page numbers. The first entry in the
// first index-block contains the database page number corresponding to the
// first frame in the WAL file. The first entry in the second index block
// in the WAL file corresponds to the (HASHTABLE_NPAGE_ONE+1)th frame in
// the log, and so on.
//
// The last index block in a wal-index usually contains less than the full
// complement of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE) page-numbers,
// depending on the contents of the WAL file. This does not change the
// allocated size of the page-mapping array - the page-mapping array merely
// contains unused entries.
//
// Even without using the hash table, the last frame for page P
// can be found by scanning the page-mapping sections of each index block
// starting with the last index block and moving toward the first, and
// within each index block, starting at the end and moving toward the
// beginning.  The first entry that equals P corresponds to the frame
// holding the content for that page.
//
// The hash table consists of HASHTABLE_NSLOT 16-bit unsigned integers.
// HASHTABLE_NSLOT = 2*HASHTABLE_NPAGE, and there is one entry in the
// hash table for each page number in the mapping section, so the hash
// table is never more than half full.  The expected number of collisions
// prior to finding a match is 1.  Each entry of the hash table is an
// 1-based index of an entry in the mapping section of the same
// index block.   Let K be the 1-based index of the largest entry in
// the mapping section.  (For index blocks other than the last, K will
// always be exactly HASHTABLE_NPAGE (4096) and for the last index block
// K will be (mxFrame%HASHTABLE_NPAGE).)  Unused slots of the hash table
// contain a value of 0.
//
// To look for page P in the hash table, first compute a hash iKey on
// P as follows:
//
//      iKey = (P * 383) % HASHTABLE_NSLOT
//
// Then start scanning entries of the hash table, starting with iKey
// (wrapping around to the beginning when the end of the hash table is
// reached) until an unused hash slot is found. Let the first unused slot
// be at index iUnused.  (iUnused might be less than iKey if there was
// wrap-around.) Because the hash table is never more than half full,
// the search is guaranteed to eventually hit an unused entry.  Let
// iMax be the value between iKey and iUnused, closest to iUnused,
// where aHash[iMax]==P.  If there is no iMax entry (if there exists
// no hash slot such that aHash[i]==p) then page P is not in the
// current index block.  Otherwise the iMax-th mapping entry of the
// current index block corresponds to the last entry that references
// page P.
//
// A hash search begins with the last index block and moves toward the
// first index block, looking for entries corresponding to page P.  On
// average, only two or three slots in each index block need to be
// examined in order to either find the last entry for page P, or to
// establish that no such entry exists in the block.  Each index block
// holds over 4000 entries.  So two or three index blocks are sufficient
// to cover a typical 10 megabyte WAL file, assuming 1K pages.  8 or 10
// comparisons (on average) suffice to either locate a frame in the
// WAL or to establish that the frame does not exist in the WAL.  This
// is much faster than scanning the entire 10MB WAL.
//
// Note that entries are added in order of increasing K.  Hence, one
// reader might be using some value K0 and a second reader that started
// at a later time (after additional transactions were added to the WAL
// and to the wal-index) might be using a different value K1, where K1>K0.
// Both readers can use the same hash table and mapping section to get
// the correct result.  There may be entries in the hash table with
// K>K0 but to the first reader, those entries will appear to be unused
// slots in the hash table and so the first reader will get an answer as
// if no values greater than K0 had ever been inserted into the hash table
// in the first place - which is what reader one wants.  Meanwhile, the
// second reader using K1 will see additional values that were inserted
// later, which is exactly what reader two wants.
//
// When a rollback occurs, the value of K is decreased. Hash table entries
// that correspond to frames greater than the new K value are removed
// from the hash table at this point.

//
// If a client begins recovering a WAL file and finds that (a) the checksum
// values in the wal-header are correct and (b) the version field is not
// WAL_MAX_VERSION, recovery fails and SQLite returns SQLITE_CANTOPEN.
//
// Similarly, if a client successfully reads a wal-index header (i.e. the

//
// Technically, the various VFSes are free to implement these locks however

// The purpose of the wal-index is to answer this question quickly:  Given
// a page number P and a maximum frame index M, return the index of the
// last frame in the wal before frame M for page P in the WAL, or return
// NULL if there are no frames for page P in the WAL prior to M.
//
// The wal-index consists of a header region, followed by an one or
// more index blocks.
//
// The wal-index header contains the total number of frames within the WAL
// in the mxFrame field.
//
// Each index block except for the first contains information on
// HASHTABLE_NPAGE frames. The first index block contains information on
// HASHTABLE_NPAGE_ONE frames. The values of HASHTABLE_NPAGE_ONE and
// HASHTABLE_NPAGE are selected so that together the wal-index header and
// first index block are the same size as all other index blocks in the
// wal-index.  The values are:
//
//   HASHTABLE_NPAGE      4096
//   HASHTABLE_NPAGE_ONE  4062
//
// Each index block contains two sections, a page-mapping that contains the
// database page number associated with each wal frame, and a hash-table
// that allows readers to query an index block for a specific page number.
// The page-mapping is an array of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE
// for the first index block) 32-bit page numbers. The first entry in the
// first index-block contains the database page number corresponding to the
// first frame in the WAL file. The first entry in the second index block
// in the WAL file corresponds to the (HASHTABLE_NPAGE_ONE+1)th frame in
// the log, and so on.
//
// The last index block in a wal-index usually contains less than the full
// complement of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE) page-numbers,
// depending on the contents of the WAL file. This does not change the
// allocated size of the page-mapping array - the page-mapping array merely
// contains unused entries.
//
// Even without using the hash table, the last frame for page P
// can be found by scanning the page-mapping sections of each index block
// starting with the last index block and moving toward the first, and
// within each index block, starting at the end and moving toward the
// beginning.  The first entry that equals P corresponds to the frame
// holding the content for that page.
//
// The hash table consists of HASHTABLE_NSLOT 16-bit unsigned integers.
// HASHTABLE_NSLOT = 2*HASHTABLE_NPAGE, and there is one entry in the
// hash table for each page number in the mapping section, so the hash
// table is never more than half full.  The expected number of collisions
// prior to finding a match is 1.  Each entry of the hash table is an
// 1-based index of an entry in the mapping section of the same
// index block.   Let K be the 1-based index of the largest entry in
// the mapping section.  (For index blocks other than the last, K will
// always be exactly HASHTABLE_NPAGE (4096) and for the last index block
// K will be (mxFrame%HASHTABLE_NPAGE).)  Unused slots of the hash table
// contain a value of 0.
//
// To look for page P in the hash table, first compute a hash iKey on
// P as follows:
//
//      iKey = (P * 383) % HASHTABLE_NSLOT
//
// Then start scanning entries of the hash table, starting with iKey
// (wrapping around to the beginning when the end of the hash table is
// reached) until an unused hash slot is found. Let the first unused slot
// be at index iUnused.  (iUnused might be less than iKey if there was
// wrap-around.) Because the hash table is never more than half full,
// the search is guaranteed to eventually hit an unused entry.  Let
// iMax be the value between iKey and iUnused, closest to iUnused,
// where aHash[iMax]==P.  If there is no iMax entry (if there exists
// no hash slot such that aHash[i]==p) then page P is not in the
// current index block.  Otherwise the iMax-th mapping entry of the
// current index block corresponds to the last entry that references
// page P.
//
// A hash search begins with the last index block and moves toward the
// first index block, looking for entries corresponding to page P.  On
// average, only two or three slots in each index block need to be
// examined in order to either find the last entry for page P, or to
// establish that no such entry exists in the block.  Each index block
// holds over 4000 entries.  So two or three index blocks are sufficient
// to cover a typical 10 megabyte WAL file, assuming 1K pages.  8 or 10
// comparisons (on average) suffice to either locate a frame in the
// WAL or to establish that the frame does not exist in the WAL.  This
// is much faster than scanning the entire 10MB WAL.
//
// Note that entries are added in order of increasing K.  Hence, one
// reader might be using some value K0 and a second reader that started
// at a later time (after additional transactions were added to the WAL
// and to the wal-index) might be using a different value K1, where K1>K0.
// Both readers can use the same hash table and mapping section to get
// the correct result.  There may be entries in the hash table with
// K>K0 but to the first reader, those entries will appear to be unused
// slots in the hash table and so the first reader will get an answer as
// if no values greater than K0 had ever been inserted into the hash table
// in the first place - which is what reader one wants.  Meanwhile, the
// second reader using K1 will see additional values that were inserted
// later, which is exactly what reader two wants.
//
// When a rollback occurs, the value of K is decreased. Hash table entries
// that correspond to frames greater than the new K value are removed
// from the hash table at this point.

// If a client begins recovering a WAL file and finds that (a) the checksum

// Similarly, if a client successfully reads a wal-index header (i.e. the

// Technically, the various VFSes are free to implement these locks however

// locks are on the shm file.  The WALINDEX_LOCK_OFFSET constant (which

// bad luck when there is lots of contention for the wal-index, but that
// possibility is so small that it can be safely neglected, we believe.

// that means the Wal does not hold any read lock.  The reader must not
// access any database page that is modified by a WAL frame up to and
// including frame number aReadMark[pWal->readLock].  The reader will
// use WAL frames up to and including pWal->hdr.mxFrame if pWal->readLock>0
// Or if pWal->readLock==0, then the reader will ignore the WAL
// completely and get all content directly from the database file.
// If the useWal parameter is 1 then the WAL will never be ignored and

// When the read transaction is completed, the caller must release the
// lock on WAL_READ_LOCK(pWal->readLock) and set pWal->readLock to -1.
//
// This routine uses the nBackfill and aReadMark[] fields of the header
// to select a particular WAL_READ_LOCK() that strives to let the

//
// The basic idea is that each page of the file contains N database
// entries and N+1 pointers to subpages.
//
//   ----------------------------------------------------------------
//   |  Ptr(0) | Key(0) | Ptr(1) | Key(1) | ... | Key(N-1) | Ptr(N) |
//   ----------------------------------------------------------------
//
// All of the keys on the page that Ptr(0) points to have values less
// than Key(0).  All of the keys on page Ptr(1) and its subpages have
// values greater than Key(0) and less than Key(1).  All of the keys
// on Ptr(N) and its subpages have values greater than Key(N-1).  And
// so forth.
//
// Finding a particular key requires reading O(log(M)) pages from the
// disk where M is the number of entries in the tree.
//
// In this implementation, a single file can hold one or more separate
// BTrees.  Each BTree is identified by the index of its root page.  The
// key and data for any entry are combined to form the "payload".  A
// fixed amount of payload can be carried directly on the database
// page.  If the payload is larger than the preset amount then surplus
// bytes are stored on overflow pages.  The payload for an entry
// and the preceding pointer are combined to form a "Cell".  Each
// page has a small header which contains the Ptr(N) pointer and other
// information such as the size of key and data.
//
// FORMAT DETAILS
//
// The file is divided into pages.  The first page is called page 1,
// the second is page 2, and so forth.  A page number of zero indicates
// "no such page".  The page size can be any power of 2 between 512 and 65536.
// Each page can be either a btree page, a freelist page, an overflow
// page, or a pointer-map page.
//
// The first page is always a btree page.  The first 100 bytes of the first
// page contain a special header (the "file header") that describes the file.
// The format of the file header is as follows:
//
//   OFFSET   SIZE    DESCRIPTION
//      0      16     Header string: "SQLite format 3\000"
//     16       2     Page size in bytes.  (1 means 65536)
//     18       1     File format write version
//     19       1     File format read version
//     20       1     Bytes of unused space at the end of each page
//     21       1     Max embedded payload fraction (must be 64)
//     22       1     Min embedded payload fraction (must be 32)
//     23       1     Min leaf payload fraction (must be 32)
//     24       4     File change counter
//     28       4     Reserved for future use

//     36       4     Number of freelist pages in the file
//     40      60     15 4-byte meta values passed to higher layers
//
//     40       4     Schema cookie
//     44       4     File format of schema layer
//     48       4     Size of page cache
//     52       4     Largest root-page (auto/incr_vacuum)
//     56       4     1=UTF-8 2=UTF16le 3=UTF16be

//     64       4     Incremental vacuum mode
//     68       4     Application-ID
//     72      20     unused
//     92       4     The version-valid-for number
//     96       4     SQLITE_VERSION_NUMBER
//
// All of the integer values are big-endian (most significant byte first).
//
// The file change counter is incremented when the database is changed
// This counter allows other processes to know when the file has changed
// and thus when they need to flush their cache.
//
// The max embedded payload fraction is the amount of the total usable
// space in a page that can be consumed by a single cell for standard
// B-tree (non-LEAFDATA) tables.  A value of 255 means 100%.  The default
// is to limit the maximum cell size so that at least 4 cells will fit
// on one page.  Thus the default max embedded payload fraction is 64.
//
// If the payload for a cell is larger than the max payload, then extra
// payload is spilled to overflow pages.  Once an overflow page is allocated,
// as many bytes as possible are moved into the overflow pages without letting
// the cell size drop below the min embedded payload fraction.
//
// The min leaf payload fraction is like the min embedded payload fraction
// except that it applies to leaf nodes in a LEAFDATA tree.  The maximum
// payload fraction for a LEAFDATA tree is always 100% (or 255) and it
// not specified in the header.
//
// Each btree pages is divided into three sections:  The header, the
// cell pointer array, and the cell content area.  Page 1 also has a 100-byte
// file header that occurs before the page header.
//
//      |----------------|
//      | file header    |   100 bytes.  Page 1 only.
//      |----------------|
//      | page header    |   8 bytes for leaves.  12 bytes for interior nodes

//      | area           |   |  and free space fragments.
//      |----------------|
//
// The page headers looks like this:
//
//   OFFSET   SIZE     DESCRIPTION
//      0       1      Flags. 1: intkey, 2: zerodata, 4: leafdata, 8: leaf
//      1       2      byte offset to the first freeblock
//      3       2      number of cells on this page
//      5       2      first byte of the cell content area
//      7       1      number of fragmented free bytes
//      8       4      Right child (the Ptr(N) value).  Omitted on leaves.
//
// The flags define the format of this btree page.  The leaf flag means that
// this page has no children.  The zerodata flag means that this page carries
// only keys and no data.  The intkey flag means that the key is an integer
// which is stored in the key size entry of the cell header rather than in
// the payload area.
//
// The cell pointer array begins on the first byte after the page header.
// The cell pointer array contains zero or more 2-byte numbers which are
// offsets from the beginning of the page to the cell content in the cell
// content area.  The cell pointers occur in sorted order.  The system strives
// to keep free space after the last cell pointer so that new cells can
// be easily added without having to defragment the page.
//
// Cell content is stored at the very end of the page and grows toward the
// beginning of the page.
//
// Unused space within the cell content area is collected into a linked list of
// freeblocks.  Each freeblock is at least 4 bytes in size.  The byte offset
// to the first freeblock is given in the header.  Freeblocks occur in
// increasing order.  Because a freeblock must be at least 4 bytes in size,
// any group of 3 or fewer unused bytes in the cell content area cannot
// exist on the freeblock chain.  A group of 3 or fewer free bytes is called
// a fragment.  The total number of bytes in all fragments is recorded.
// in the page header at offset 7.
//
//    SIZE    DESCRIPTION
//      2     Byte offset of the next freeblock
//      2     Bytes in this freeblock
//
// Cells are of variable length.  Cells are stored in the cell content area at
// the end of the page.  Pointers to the cells are in the cell pointer array
// that immediately follows the page header.  Cells is not necessarily
// contiguous or in order, but cell pointers are contiguous and in order.
//
// Cell content makes use of variable length integers.  A variable
// length integer is 1 to 9 bytes where the lower 7 bits of each
// byte are used.  The integer consists of all bytes that have bit 8 set and
// the first byte with bit 8 clear.  The most significant byte of the integer
// appears first.  A variable-length integer may not be more than 9 bytes long.
// As a special case, all 8 bytes of the 9th byte are used as data.  This
// allows a 64-bit integer to be encoded in 9 bytes.
//
//    0x00                      becomes  0x00000000
//    0x7f                      becomes  0x0000007f
//    0x81 0x00                 becomes  0x00000080
//    0x82 0x00                 becomes  0x00000100
//    0x80 0x7f                 becomes  0x0000007f

//    0x81 0x81 0x81 0x81 0x01  becomes  0x10204081
//
// Variable length integers are used for rowids and to hold the number of

//
// The content of a cell looks like this:
//
//    SIZE    DESCRIPTION
//      4     Page number of the left child. Omitted if leaf flag is set.
//     var    Number of bytes of data. Omitted if the zerodata flag is set.
//     var    Number of bytes of key. Or the key itself if intkey flag is set.
//      *     Payload
//      4     First page of the overflow chain.  Omitted if no overflow
//
// Overflow pages form a linked list.  Each page except the last is completely
// filled with data (pagesize - 4 bytes).  The last page can have as little
// as 1 byte of data.
//
//    SIZE    DESCRIPTION
//      4     Page number of next overflow page
//      *     Data
//
// Freelist pages come in two subtypes: trunk pages and leaf pages.  The
// file header points to the first in a linked list of trunk page.  Each trunk
// page points to multiple leaf pages.  The content of a leaf page is
// unspecified.  A trunk page looks like this:
//
//    SIZE    DESCRIPTION
//      4     Page number of next trunk page
//      4     Number of leaf pointers on this page
//      *     zero or more pages numbers of leaves
// #include "sqliteInt.h"

// The following value is the maximum cell size assuming a maximum page
// size give above.

// The maximum number of cells on a single page of the database.  This
// assumes a minimum cell size of 6 bytes  (4 bytes for the cell itself
// plus 2 bytes for the index to the cell in the page header).  Such
// small cells will be rare, but they are possible.

// Set bit pgno of the BtShared.pHasContent bitvec. This is called

// The BtShared.pHasContent bitvec exists to work around an obscure
// bug caused by the interaction of two useful IO optimizations surrounding
// free-list leaf pages:
//
//   1) When all data is deleted from a page and the page becomes
//      a free-list leaf page, the page is not written to the database
//      (as free-list leaf pages contain no meaningful data). Sometimes
//      such a page is not even journalled (as it will not be modified,
//      why bother journalling it?).
//
//   2) When a free-list leaf page is reused, its content is not read
//      from the database or written to the journal file (why should it
//      be, if it is not at all meaningful?).
//
// By themselves, these optimizations work fine and provide a handy
// performance boost to bulk delete or insert operations. However, if
// a page is moved to the free-list and then reused within the same
// transaction, a problem comes up. If the page is not journalled when
// it is moved to the free-list and it is also not journalled when it
// is extracted from the free-list and reused, then the original data
// may be lost. In the event of a rollback, it may not be possible
// to restore the database to its original configuration.
//
// The solution is the BtShared.pHasContent bitvec. Whenever a page is
// moved to become a free-list leaf page, the corresponding bit is
// set in the bitvec. Whenever a leaf page is extracted from the free-list,
// optimization 2 above is omitted if the corresponding bit is already
// set in BtShared.pHasContent. The contents of the bitvec are cleared
// at the end of every transaction.

// rowid or INTEGER PRIMARY KEY of the row.  The pX.nData,pData,nZero fields
// hold the content of the row.
//
// For an index btree (used for indexes and WITHOUT ROWID tables), the
// key is an arbitrary byte sequence stored in pX.pKey,nKey.  The
// pX.pData,nData,nZero fields must be zero.
//
// If the seekResult parameter is non-zero, then a successful call to
// sqlite3BtreeIndexMoveto() to seek cursor pCur to (pKey,nKey) has already
// been performed.  In other words, if seekResult!=0 then the cursor
// is currently pointing to a cell that will be adjacent to the cell
// to be inserted.  If seekResult<0 then pCur points to a cell that is
// smaller then (pKey,nKey).  If seekResult>0 then pCur points to a cell
// that is larger than (pKey,nKey).
//
// If seekResult==0, that means pCur is pointing at some unknown location.
// In that case, this routine must seek the cursor to the correct insertion
// point for (pKey,nKey) before doing the insertion.  For index btrees,
// if pX->nMem is non-zero, then pX->aMem contains pointers to the unpacked
// key values and pX->aMem can be used instead of pX->pKey to avoid having

//   structure may be accessed via two groups of thread-safe entry points:
//
//     * Via the sqlite3_backup_XXX() API function backup_step() and
//       backup_finish(). Both these functions obtain the source database
//       handle mutex and the mutex associated with the source BtShared
//       structure, in that order.
//
//     * Via the BackupUpdate() and BackupRestart() functions, which are
//       invoked by the pager layer to report various state changes in
//       the page cache associated with the source database. The mutex
//       associated with the source database BtShared structure will always
//       be held when either of these functions are invoked.
//
//   The other sqlite3_backup_XXX() API functions, backup_remaining() and
//   backup_pagecount() are not thread-safe functions. If they are called
//   while some other thread is calling backup_step() or backup_finish(),
//   the values returned may be invalid. There is no way for a call to
//   BackupUpdate() or BackupRestart() to interfere with backup_remaining()
//   or backup_pagecount().
//
//   Depending on the SQLite configuration, the database handles and/or
//   the Btree objects may have their own mutexes that require locking.
//   Non-sharable Btrees (in-memory databases for example), do not have
//   associated mutexes.

// always taken, the flags should be 0x05 since the fall-through and
// alternate branch are never taken.  If a branch is never taken then
// flags should be 0x06 since only the fall-through approach is allowed.

	// What follows is a massive switch statement where each case implements a
	// separate instruction in the virtual machine.  If we follow the usual
	// indentation conventions, each case should be indented by 6 spaces.  But
	// that is a lot of wasted space on the left margin.  So the code within
	// the switch statement will break with convention and be flush-left. Another
	// big comment (similar to this one) will mark the point in the code where
	// we transition back to normal indentation.
	//
	// The formatting of each case is important.  The makefile for SQLite
	// generates two C files "opcodes.h" and "opcodes.c" by scanning this
	// file looking for lines that begin with "case OP_".  The opcodes.h files
	// will be filled with #defines that give unique integer values to each
	// opcode and the opcodes.c file is filled with an array of strings where
	// each string is the symbolic name for the corresponding opcode.  If the
	// case statement is followed by a comment of the form "/# same as ... #/"
	// that comment is used to determine the particular value of the opcode.
	//
	// Other keywords in the comment that follows each case are used to
	// construct the OPFLG_INITIALIZER value that initializes opcodeProperty[].
	// Keywords include: in1, in2, in3, out2, out3.  See
	// the mkopcodeh.awk script for additional information.
	//
	// Documentation about VDBE opcodes is generated by scanning this file
	// for lines of that contain "Opcode:".  That line and all subsequent

	// file.

	// that this Goto is the bottom of a loop and that the lines from P2 down

	// If P3 is 1, then the jump is only taken if register P1 holds an integer

	// OP_Return becomes a no-op. If P3 is 0, then register P1 must hold an
	// integer or else an assert() is raised.  P3 should be set to 1 when
	// this opcode is used in combination with OP_BeginSubrtn, and set to 0

	//
	// P2 is not used by the byte-code engine.  However, if P2 is positive
	// and also less than the current address, then the "EXPLAIN" output
	// formatter in the CLI will indent all opcodes from the P2 opcode up
	// to be not including the current Return.   P2 should be the first opcode

	// This opcode is a prefix opcode to OP_SeekGE.  In other words, this
	// opcode must be immediately followed by OP_SeekGE. This constraint is
	// checked by assert() statements.
	//
	// This opcode uses the P1 through P4 operands of the subsequent
	// OP_SeekGE.  In the text that follows, the operands of the subsequent
	// OP_SeekGE opcode are denoted as SeekOP.P1 through SeekOP.P4.   Only
	// the P1 and P2 operands of this opcode are also used, and  are called
	// This.P1 and This.P2.
	//
	// This opcode helps to optimize IN operators on a multi-column index
	// where the IN operator is on the later terms of the index by avoiding
	// unnecessary seeks on the btree, substituting steps to the next row
	// of the b-tree instead.  A correct answer is obtained if this opcode
	// is omitted or is a no-op.
	//
	// The SeekGE.P3 and SeekGE.P4 operands identify an unpacked key which
	// is the desired entry that we want the cursor SeekGE.P1 to be pointing
	// to.  Call this SeekGE.P4/P5 row the "target".
	//
	// If the SeekGE.P1 cursor is not currently pointing to a valid row,
	// then this opcode is a no-op and control passes through into the OP_SeekGE.
	//
	// If the SeekGE.P1 cursor is pointing to a valid row, then that row
	// might be the target row, or it might be near and slightly before the
	// target row.  This opcode attempts to position the cursor on the target
	// row by, perhaps by invoking sqlite3BtreeStep() on the cursor
	// between 0 and This.P1 times.
	//
	// There are three possible outcomes from this opcode:<ol>
	//
	// <li> If after This.P1 steps, the cursor is still pointing to a place that
	//      is earlier in the btree than the target row, then fall through
	//      into the subsquence OP_SeekGE opcode.
	//
	// <li> If the cursor is successfully moved to the target row by 0 or more
	//      sqlite3BtreeNext() calls, then jump to This.P2, which will land just
	//      past the OP_IdxGT or OP_IdxGE opcode that follows the OP_SeekGE.
	//

//                                  in the case of a SELECT w/ ORDER BY, or

//    sqlite3VdbeSorterClose()      Close the VdbeSorter object and reclaim
//                                  all resources.
//
//    sqlite3VdbeSorterReset()      Refurbish the VdbeSorter for reuse.  This
//                                  is like Close() followed by Init() only
//                                  much faster.
//
// The interfaces above must be called in a particular order.  Write() can
// only occur in between Init()/Reset() and Rewind().  Next(), Rowkey(), and
// Compare() can only occur in between Rewind() and Close()/Reset(). i.e.
//
//   Init()
//   for each record: Write()
//   Rewind()
//     Rowkey()/Compare()
//   Next()
//   Close()
//
// Algorithm:
//
// Records passed to the sorter via calls to Write() are initially held
// unsorted in main memory. Assuming the amount of memory used never exceeds
// a threshold, when Rewind() is called the set of records is sorted using
// an in-memory merge sort. In this case, no temporary files are required
// and subsequent calls to Rowkey(), Next() and Compare() read records
// directly from main memory.
//
// If the amount of space used to store records in main memory exceeds the
// threshold, then the set of records currently in memory are sorted and
// written to a temporary file in "Packed Memory Array" (PMA) format.
// A PMA created at this point is known as a "level-0 PMA". Higher levels
// of PMAs may be created by merging existing PMAs together - for example
// merging two or more level-0 PMAs together creates a level-1 PMA.
//
// The threshold for the amount of main memory to use before flushing
// records to a PMA is roughly the same as the limit configured for the
// page-cache of the main database. Specifically, the threshold is set to
// the value returned by "PRAGMA main.page_size" multipled by
// that returned by "PRAGMA main.cache_size", in bytes.
//
// If the sorter is running in single-threaded mode, then all PMAs generated
// are appended to a single temporary file. Or, if the sorter is running in
// multi-threaded mode then up to (N+1) temporary files may be opened, where
// N is the configured number of worker threads. In this case, instead of
// sorting the records and writing the PMA to a temporary file itself, the
// calling thread usually launches a worker thread to do so. Except, if
// there are already N worker threads running, the main thread does the work
// itself.
//
// The sorter is running in multi-threaded mode if (a) the library was built
// with pre-processor symbol SQLITE_MAX_WORKER_THREADS set to a value greater
// than zero, and (b) worker threads have been enabled at runtime by calling
// "PRAGMA threads=N" with some value of N greater than 0.
//
// When Rewind() is called, any data remaining in memory is flushed to a
// final PMA. So at this point the data is stored in some number of sorted
// PMAs within temporary files on disk.
//
// If there are fewer than SORTER_MAX_MERGE_COUNT PMAs in total and the
// sorter is running in single-threaded mode, then these PMAs are merged
// incrementally as keys are retreived from the sorter by the VDBE.  The
// MergeEngine object, described in further detail below, performs this
// merge.
//
// Or, if running in multi-threaded mode, then a background thread is
// launched to merge the existing PMAs. Once the background thread has
// merged T bytes of data into a single sorted PMA, the main thread
// begins reading keys from that PMA while the background thread proceeds
// with merging the next T bytes of data. And so on.
//
// Parameter T is set to half the value of the memory threshold used
// by Write() above to determine when to create a new PMA.
//
// If there are more than SORTER_MAX_MERGE_COUNT PMAs in total when
// Rewind() is called, then a hierarchy of incremental-merges is used.
// First, T bytes of data from the first SORTER_MAX_MERGE_COUNT PMAs on
// disk are merged together. Then T bytes of data from the second set, and
// so on, such that no operation ever merges more than SORTER_MAX_MERGE_COUNT
// PMAs at a time. This done is to improve locality.
//
// If running in multi-threaded mode and there are more than
// SORTER_MAX_MERGE_COUNT PMAs on disk when Rewind() is called, then more
// than one background thread may be created. Specifically, there may be
// one background thread for each temporary file on disk, and one background
// thread to merge the output of each of the others to a single PMA for
// the main thread to read from.

// This routine walks an expression tree and resolves references to

// are seen.
//
// To resolve table columns references we look for nodes (or subtrees) of the
// form X.Y.Z or Y.Z or just Z where
//
//      X:   The name of a database.  Ex:  "main" or "temp" or
//           the symbolic name assigned to an ATTACH-ed database.
//
//      Y:   The name of a table in a FROM clause.  Or in a trigger
//           one of the special names "old" or "new".
//
//      Z:   The name of a column in table Y.
//
// The node at the root of the subtree is modified as follows:
//
//    Expr.op        Changed to TK_COLUMN
//    Expr.pTab      Points to the Table object for X.Y
//    Expr.iColumn   The column index in X.Y.  -1 for the rowid.
//    Expr.iTable    The VDBE cursor number for X.Y
//
//
// To resolve result-set references, look for expression nodes of the
// form Z (with no X and Y prefix) where the Z matches the right-hand
// size of an AS clause in the result-set of a SELECT.  The Z expression
// is replaced by a copy of the left-hand side of the result-set expression.
// Table-name and function resolution occurs on the substituted expression
// tree.  For example, in:
//
//      SELECT a+b AS x, c+d AS y FROM t1 ORDER BY x;
//
// The "x" term of the order by is replaced by "a+b" to render:
//
//      SELECT a+b AS x, c+d AS y FROM t1 ORDER BY a+b;
//
// Function calls are checked to make sure that the function is
// defined and that the correct number of arguments are specified.
// If the function is an aggregate function, then the NC_HasAgg flag is
// set and the opcode is changed from TK_FUNCTION to TK_AGG_FUNCTION.
// If an expression contains aggregate functions then the EP_Agg
// property on the expression is set.
//
// An error message is left in pParse if anything is amiss.  The number
// if errors is returned.

// This function is used by the implementation of the IN (...) operator.
// The pX parameter is the expression on the RHS of the IN operator, which
// might be either a list of expressions or a subquery.
//
// The job of this routine is to find or create a b-tree object that can
// be used either to test for membership in the RHS set or to iterate through
// all members of the RHS set, skipping duplicates.
//
// A cursor is opened on the b-tree object that is the RHS of the IN operator
// and the *piTab parameter is set to the index of that cursor.
//
// The returned value of this function indicates the b-tree type, as follows:
//
//   IN_INDEX_ROWID      - The cursor was opened on a database table.
//   IN_INDEX_INDEX_ASC  - The cursor was opened on an ascending index.
//   IN_INDEX_INDEX_DESC - The cursor was opened on a descending index.
//   IN_INDEX_EPH        - The cursor was opened on a specially created and
//                         populated epheremal table.
//   IN_INDEX_NOOP       - No cursor was allocated.  The IN operator must be
//                         implemented as a sequence of comparisons.
//
// An existing b-tree might be used if the RHS expression pX is a simple
// subquery such as:
//
//     SELECT <column1>, <column2>... FROM <table>
//
// If the RHS of the IN operator is a list or a more complex subquery, then
// an ephemeral table might need to be generated from the RHS and then
// pX->iTable made to point to the ephemeral table instead of an
// existing table.  In this case, the creation and initialization of the
// ephmeral table might be put inside of a subroutine, the EP_Subrtn flag
// will be set on pX and the pX->y.sub fields will be set to show where
// the subroutine is coded.
//
// The inFlags parameter must contain, at a minimum, one of the bits
// IN_INDEX_MEMBERSHIP or IN_INDEX_LOOP but not both.  If inFlags contains
// IN_INDEX_MEMBERSHIP, then the generated table will be used for a fast
// membership test.  When the IN_INDEX_LOOP bit is set, the IN index will
// be used to loop over all values of the RHS of the IN operator.
//
// When IN_INDEX_LOOP is used (and the b-tree will be used to iterate
// through the set members) then the b-tree must not contain duplicates.
// An epheremal table will be created unless the selected columns are guaranteed
// to be unique - either because it is an INTEGER PRIMARY KEY or due to
// a UNIQUE constraint or index.
//
// When IN_INDEX_MEMBERSHIP is used (and the b-tree will be used
// for fast set membership tests) then an epheremal table must
// be used unless <columns> is a single INTEGER PRIMARY KEY column or an
// index can be found with the specified <columns> as its left-most.
//
// If the IN_INDEX_NOOP_OK and IN_INDEX_MEMBERSHIP are both set and
// if the RHS of the IN operator is a list (not a subquery) then this
// routine might decide that creating an ephemeral b-tree for membership
// testing is too expensive and return IN_INDEX_NOOP.  In that case, the
// calling routine should implement the IN operator using a sequence
// of Eq or Ne comparison operations.
//
// When the b-tree is being used for membership tests, the calling function
// might need to know whether or not the RHS side of the IN operator
// contains a NULL.  If prRhsHasNull is not a NULL pointer and
// if there is any chance that the (...) might contain a NULL value at
// runtime, then a register is allocated and the register number written
// to *prRhsHasNull. If there is no chance that the (...) contains a
// NULL value, then *prRhsHasNull is left unchanged.
//
// If a register is allocated and its location stored in *prRhsHasNull, then
// the value in that register will be NULL if the b-tree contains one or more
// NULL values, and it will be some non-NULL value if the b-tree contains no
// NULL values.
//
// If the aiMap parameter is not NULL, it must point to an array containing
// one element for each column returned by the SELECT statement on the RHS
// of the IN(...) operator. The i'th entry of the array is populated with the
// offset of the index column that matches the i'th column returned by the
// SELECT. For example, if the expression and selected index are:
//
//   (?,?,?) IN (SELECT a, b, c FROM t1)
//   CREATE INDEX i1 ON t1(b, c, a);
//
// then aiMap[] is populated with {2, 0, 1}.

//
// This file contains code associated with the ANALYZE command.
//
// The ANALYZE command gather statistics about the content of tables
// and indices.  These statistics are made available to the query planner
// to help it make better decisions about how to perform queries.
//
// The following system tables are or have been supported:
//
//    CREATE TABLE sqlite_stat1(tbl, idx, stat);
//    CREATE TABLE sqlite_stat2(tbl, idx, sampleno, sample);
//    CREATE TABLE sqlite_stat3(tbl, idx, nEq, nLt, nDLt, sample);
//    CREATE TABLE sqlite_stat4(tbl, idx, nEq, nLt, nDLt, sample);
//
// Additional tables might be added in future releases of SQLite.
// The sqlite_stat2 table is not created or used unless the SQLite version
// is between 3.6.18 and 3.7.8, inclusive, and unless SQLite is compiled
// with SQLITE_ENABLE_STAT2.  The sqlite_stat2 table is deprecated.
// The sqlite_stat2 table is superseded by sqlite_stat3, which is only
// created and used by SQLite versions 3.7.9 through 3.29.0 when
// SQLITE_ENABLE_STAT3 defined.  The functionality of sqlite_stat3
// is a superset of sqlite_stat2 and is also now deprecated.  The
// sqlite_stat4 is an enhanced version of sqlite_stat3 and is only
// available when compiled with SQLITE_ENABLE_STAT4 and in SQLite
// versions 3.8.1 and later.  STAT4 is the only variant that is still
// supported.
//
// For most applications, sqlite_stat1 provides all the statistics required
// for the query planner to make good choices.
//
// Format of sqlite_stat1:
//
// There is normally one row per index, with the index identified by the
// name in the idx column.  The tbl column is the name of the table to
// which the index belongs.  In each such row, the stat column will be
// a string consisting of a list of integers.  The first integer in this
// list is the number of rows in the index.  (This is the same as the
// number of rows in the table, except for partial indices.)  The second
// integer is the average number of rows in the index that have the same
// value in the first column of the index.  The third integer is the average
// number of rows in the index that have the same value for the first two
// columns.  The N-th integer (for N>1) is the average number of rows in
// the index which have the same value for the first N-1 columns.  For
// a K-column index, there will be K+1 integers in the stat column.  If
// the index is unique, then the last integer will be 1.
//
// The list of integers in the stat column can optionally be followed
// by the keyword "unordered".  The "unordered" keyword, if it is present,
// must be separated from the last integer by a single space.  If the
// "unordered" keyword is present, then the query planner assumes that
// the index is unordered and will not use the index for a range query.
//
// If the sqlite_stat1.idx column is NULL, then the sqlite_stat1.stat
// column contains a single integer which is the (estimated) number of
// rows in the table identified by sqlite_stat1.tbl.
//
// Format of sqlite_stat2:
//
// The sqlite_stat2 is only created and is only used if SQLite is compiled
// with SQLITE_ENABLE_STAT2 and if the SQLite version number is between
// 3.6.18 and 3.7.8.  The "stat2" table contains additional information
// about the distribution of keys within an index.  The index is identified by
// the "idx" column and the "tbl" column is the name of the table to which
// the index belongs.  There are usually 10 rows in the sqlite_stat2
// table for each index.
//
// The sqlite_stat2 entries for an index that have sampleno between 0 and 9
// inclusive are samples of the left-most key value in the index taken at
// evenly spaced points along the index.  Let the number of samples be S
// (10 in the standard build) and let C be the number of rows in the index.
// Then the sampled rows are given by:
//
//     rownumber = (i*C*2 + C)/(S*2)
//
// For i between 0 and S-1.  Conceptually, the index space is divided into
// S uniform buckets and the samples are the middle row from each bucket.
//
// The format for sqlite_stat2 is recorded here for legacy reference.  This
// version of SQLite does not support sqlite_stat2.  It neither reads nor
// writes the sqlite_stat2 table.  This version of SQLite only supports
// sqlite_stat3.
//
// Format for sqlite_stat3:
//
// The sqlite_stat3 format is a subset of sqlite_stat4.  Hence, the
// sqlite_stat4 format will be described first.  Further information
// about sqlite_stat3 follows the sqlite_stat4 description.
//
// Format for sqlite_stat4:
//
// As with sqlite_stat2, the sqlite_stat4 table contains histogram data
// to aid the query planner in choosing good indices based on the values
// that indexed columns are compared against in the WHERE clauses of
// queries.
//
// The sqlite_stat4 table contains multiple entries for each index.
// The idx column names the index and the tbl column is the table of the
// index.  If the idx and tbl columns are the same, then the sample is
// of the INTEGER PRIMARY KEY.  The sample column is a blob which is the
// binary encoding of a key from the index.  The nEq column is a
// list of integers.  The first integer is the approximate number
// of entries in the index whose left-most column exactly matches
// the left-most column of the sample.  The second integer in nEq
// is the approximate number of entries in the index where the
// first two columns match the first two columns of the sample.
// And so forth.  nLt is another list of integers that show the approximate
// number of entries that are strictly less than the sample.  The first
// integer in nLt contains the number of entries in the index where the
// left-most column is less than the left-most column of the sample.
// The K-th integer in the nLt entry is the number of index entries
// where the first K columns are less than the first K columns of the
// sample.  The nDLt column is like nLt except that it contains the
// number of distinct entries in the index that are less than the
// sample.
//
// There can be an arbitrary number of sqlite_stat4 entries per index.
// The ANALYZE command will typically generate sqlite_stat4 tables
// that contain between 10 and 40 samples which are distributed across
// the key space, though not uniformly, and which include samples with
// large nEq values.
//
// Format for sqlite_stat3 redux:
//
// The sqlite_stat3 table is like sqlite_stat4 except that it only
// looks at the left-most column of the index.  The sqlite_stat3.sample
// column contains the actual value of the left-most column instead
// of a blob encoding of the complete index key as is found in
// sqlite_stat4.sample.  The nEq, nLt, and nDLt entries of sqlite_stat3
// all contain just a single integer which is the same as the first
// integer in the equivalent columns in sqlite_stat4.
// #include "sqliteInt.h"

// This routine generates code that opens the sqlite_statN tables.
// The sqlite_stat1 table is always relevant.  sqlite_stat2 is now
// obsolete.  sqlite_stat3 and sqlite_stat4 are only opened when
// appropriate compile-time options are provided.
//
// If the sqlite_statN tables do not previously exist, it is created.
//
// Argument zWhere may be a pointer to a buffer containing a table name,
// or it may be a NULL pointer. If it is not NULL, then all entries in
// the sqlite_statN tables associated with the named table are deleted.
// If zWhere==0, then code is generated to delete all stat table entries.

// Set or clear the access authorization function.
//
// The access authorization function is be called during the compilation
// phase to verify that the user has read and/or write access permission on
// various fields of the database.  The first argument to the auth function
// is a copy of the 3rd argument to this routine.  The second argument
// to the auth function is one of these constants:
//
//       SQLITE_CREATE_INDEX
//       SQLITE_CREATE_TABLE
//       SQLITE_CREATE_TEMP_INDEX
//       SQLITE_CREATE_TEMP_TABLE

// the table and the column that are being accessed.  The auth function

// SQLITE_OK is returned, it means that access is allowed.  SQLITE_DENY
// means that the SQL statement will never-run - the sqlite3_exec() call
// will return with an error.  SQLITE_IGNORE means that the SQL statement
// should run but attempts to read the specified column will return NULL
// and attempts to write the column will be ignored.

// Setting the auth function to NULL disables this hook.  The default

// Historical versions of SQLite accepted strings as column names in
// indexes and PRIMARY KEY constraints and in UNIQUE constraints.  Example:
//
//     CREATE TABLE xyz(a,b,c,d,e,PRIMARY KEY('a'),UNIQUE('b','c' COLLATE trim)
//     CREATE INDEX abc ON xyz('c','d' DESC,'e' COLLATE nocase DESC);
//
// This is goofy.  But to preserve backwards compatibility we continue to
// accept it.  This routine does the necessary conversion.  It converts
// the expression given in its argument from a TK_STRING into a TK_ID
// if the expression is just a TK_STRING with an optional COLLATE clause.
// If the expression is anything other than TK_STRING, the expression is
// unchanged.

//       of a WITHOUT ROWID table.)
//
//   2.  Read/write cursors for all indices of pTab must be open as
//       cursor number iIdxCur+i for the i-th index.
//
//   3.  The primary key for the row to be deleted must be stored in a
//       sequence of nPk memory cells starting at iPk.  If nPk==0 that means
//       that a search record formed from OP_MakeRecord is contained in the
//       single memory location iPk.
//
// eMode:
//   Parameter eMode may be passed either ONEPASS_OFF (0), ONEPASS_SINGLE, or
//   ONEPASS_MULTI.  If eMode is not ONEPASS_OFF, then the cursor
//   iDataCur already points to the row to delete. If eMode is ONEPASS_OFF
//   then this function must seek iDataCur to the entry identified by iPk
//   and nPk before reading from it.
//
//   If eMode is ONEPASS_MULTI, then this call is being made as part
//   of a ONEPASS delete that affects multiple rows. In this case, if
//   iIdxNoSeek is a valid cursor number (>=0) and is not the same as
//   iDataCur, then its position should be preserved following the delete
//   operation. Or, if iIdxNoSeek is not a valid cursor number, the
//   position of iDataCur should be preserved instead.
//
// iIdxNoSeek:
//   If iIdxNoSeek is a valid cursor number (>=0) not equal to iDataCur,
//   then it identifies an index cursor (from within array of cursors
//   starting at iIdxCur) that already points to the index entry to be deleted.
//   Except, this optimization is disabled if there are BEFORE triggers since
//   the trigger body might have moved the cursor.

// Deferred and Immediate FKs
// --------------------------
//
// Foreign keys in SQLite come in two flavours: deferred and immediate.
// If an immediate foreign key constraint is violated,
// SQLITE_CONSTRAINT_FOREIGNKEY is returned and the current
// statement transaction rolled back. If a
// deferred foreign key constraint is violated, no action is taken
// immediately. However if the application attempts to commit the
// transaction before fixing the constraint violation, the attempt fails.
//
// Deferred constraints are implemented using a simple counter associated
// with the database handle. The counter is set to zero each time a
// database transaction is opened. Each time a statement is executed
// that causes a foreign key violation, the counter is incremented. Each
// time a statement is executed that removes an existing violation from
// the database, the counter is decremented. When the transaction is
// committed, the commit fails if the current value of the counter is
// greater than zero. This scheme has two big drawbacks:
//
//   * When a commit fails due to a deferred foreign key constraint,
//     there is no way to tell which foreign constraint is not satisfied,
//     or which row it is not satisfied for.
//
//   * If the database contains foreign key violations when the
//     transaction is opened, this may cause the mechanism to malfunction.
//
// Despite these problems, this approach is adopted as it seems simpler
// than the alternatives.
//
// INSERT operations:
//
//   I.1) For each FK for which the table is the child table, search
//        the parent table for a match. If none is found increment the
//        constraint counter.
//
//   I.2) For each FK for which the table is the parent table,
//        search the child table for rows that correspond to the new
//        row in the parent table. Decrement the counter for each row
//        found (as the constraint is now satisfied).
//
// DELETE operations:
//
//   D.1) For each FK for which the table is the child table,
//        search the parent table for a row that corresponds to the
//        deleted row in the child table. If such a row is not found,
//        decrement the counter.
//
//   D.2) For each FK for which the table is the parent table, search
//        the child table for rows that correspond to the deleted row
//        in the parent table. For each found increment the counter.
//
// UPDATE operations:
//
//   An UPDATE command requires that all 4 steps above are taken, but only
//   for FK constraints for which the affected columns are actually
//   modified (values must be compared at runtime).
//
// Note that I.1 and D.1 are very similar operations, as are I.2 and D.2.
// This simplifies the implementation a bit.
//
// For the purposes of immediate FK constraints, the OR REPLACE conflict
// resolution is considered to delete rows before the new row is inserted.
// If a delete caused by OR REPLACE violates an FK constraint, an exception
// is thrown, even if the FK constraint would be satisfied after the new
// row is inserted.
//
// Immediate constraints are usually handled similarly. The only difference
// is that the counter used is stored as part of each individual statement
// object (struct Vdbe). If, after the statement has run, its immediate
// constraint counter is greater than zero,
// it returns SQLITE_CONSTRAINT_FOREIGNKEY
// and the statement transaction is rolled back. An exception is an INSERT
// statement that inserts a single row only (no triggers). In this case,
// instead of using a counter, an exception is thrown immediately if the
// INSERT violates a foreign key constraint. This is necessary as such
// an INSERT does not open a statement transaction.
//
// TODO: How should dropping a table be handled? How should renaming a
// table be handled?
//
//
// Query API Notes
// ---------------
//
// Before coding an UPDATE or DELETE row operation, the code-generator
// for those two operations needs to know whether or not the operation
// requires any FK processing and, if so, which columns of the original
// row are required by the FK processing VDBE code (i.e. if FKs were
// implemented using triggers, which of the old.* columns would be
// accessed). No information is required by the code-generator before
// coding an INSERT operation. The functions used by the UPDATE/DELETE
// generation code to query for this information are:
//
//   sqlite3FkRequired() - Test to see if FK processing is required.
//   sqlite3FkOldmask()  - Query for the set of required old.* columns.
//
//
// Externally accessible module functions
// --------------------------------------
//
//   sqlite3FkCheck()    - Check for foreign key violations.
//   sqlite3FkActions()  - Code triggers for ON UPDATE/ON DELETE actions.
//   sqlite3FkDelete()   - Delete an FKey structure.

// VDBE Calling Convention
// -----------------------
//
// Example:
//
//   For the following INSERT statement:
//
//     CREATE TABLE t1(a, b INTEGER PRIMARY KEY, c);
//     INSERT INTO t1 VALUES(1, 2, 3.1);
//
//   Register (x):        2    (type integer)
//   Register (x+1):      1    (type integer)
//   Register (x+2):      NULL (type NULL)
//   Register (x+3):      3.1  (type real)

// A foreign key constraint requires that the key columns in the parent
// table are collectively subject to a UNIQUE or PRIMARY KEY constraint.
// Given that pParent is the parent table for foreign key constraint pFKey,
// search the schema for a unique index on the parent key columns.
//
// If successful, zero is returned. If the parent key is an INTEGER PRIMARY
// KEY column, then output variable *ppIdx is set to NULL. Otherwise, *ppIdx
// is set to point to the unique index.
//
// If the parent key consists of a single column (the foreign key constraint
// is not a composite foreign key), output variable *paiCol is set to NULL.
// Otherwise, it is set to point to an allocated array of size N, where
// N is the number of columns in the parent key. The first element of the
// array is the index of the child table column that is mapped by the FK
// constraint to the parent table column stored in the left-most column
// of index *ppIdx. The second element of the array is the index of the
// child table column that corresponds to the second left-most column of
// *ppIdx, and so on.
//
// If the required index cannot be found, either because:
//
//   1) The named parent key columns do not exist, or
//
//   2) The named parent key columns do exist, but are not subject to a
//      UNIQUE or PRIMARY KEY constraint, or
//
//   3) No parent key columns were provided explicitly as part of the
//      foreign key definition, and the parent table does not have a
//      PRIMARY KEY, or
//
//   4) No parent key columns were provided explicitly as part of the
//      foreign key definition, and the PRIMARY KEY of the parent table
//      consists of a different number of columns to the child key in
//      the child table.
//
// then non-zero is returned, and a "foreign key mismatch" error loaded
// into pParse. If an OOM error occurs, non-zero is returned and the
// pParse->db->mallocFailed flag is set.

// The IDLIST appears in the pColumn parameter.  pColumn is NULL if IDLIST
// is omitted.

// for a SELECT statement that omits the FROM clause and everything else
// that follows.  If the pSelect parameter is NULL, that means that the
// DEFAULT VALUES form of the INSERT statement is intended.
//
// The code generated follows one of four templates.  For a simple
// insert with data coming from a single-row VALUES clause, the code executes
// once straight down through.  Pseudo-code follows (we call this
// the "1st template"):
//
//         open write cursor to <table> and its indices
//         put VALUES clause expressions into registers
//         write the resulting record into <table>
//         cleanup
//
// The three remaining templates assume the statement is of the form
//
//   INSERT INTO <table> SELECT ...
//
// If the SELECT clause is of the restricted form "SELECT * FROM <table2>" -
// in other words if the SELECT pulls all columns from a single table
// and there is no WHERE or LIMIT or GROUP BY or ORDER BY clauses, and
// if <table2> and <table1> are distinct tables but have identical
// schemas, including all the same indices, then a special optimization
// is invoked that copies raw records from <table2> over to <table1>.
// See the xferOptimization() function for the implementation of this
// template.  This is the 2nd template.
//
//         open a write cursor to <table>
//         open read cursor on <table2>
//         transfer all records in <table2> over to <table>
//         close cursors
//         foreach index on <table>
//           open a write cursor on the <table> index
//           open a read cursor on the corresponding <table2> index
//           transfer all records from the read to the write cursors
//           close cursors
//         end foreach
//
// The 3rd template is for when the second template does not apply
// and the SELECT clause does not read from <table> at any time.
// The generated code follows this template:
//
//         X <- A
//         goto B
//      A: setup for the SELECT
//         loop over the rows in the SELECT
//           load values into registers R..R+n
//           yield X
//         end loop
//         cleanup after the SELECT
//         end-coroutine X
//      B: open write cursor to <table> and its indices
//      C: yield X, at EOF goto D
//         insert the select result into <table> from R..R+n
//         goto C
//      D: cleanup
//
// The 4th template is used if the insert statement takes its
// values from a SELECT but the data is being inserted into a table
// that is also read as part of the SELECT.  In the third form,
// we have to use an intermediate table to store the results of
// the select.  The template is like this:
//
//         X <- A
//         goto B
//      A: setup for the SELECT
//         loop over the tables in the SELECT
//           load value into register R..R+n
//           yield X
//         end loop
//         cleanup after the SELECT
//         end co-routine R
//      B: open temp table
//      L: yield X, at EOF goto M
//         insert row from R..R+n into temp table
//         goto L
//      M: open write cursor to <table> and its indices
//         rewind temp table
//      C: loop over rows of intermediate table
//           transfer values form intermediate table into <table>

//
// The regOldData parameter is similar to regNewData except that it contains

// for an INSERT.  This routine can distinguish between UPDATE and INSERT by
// checking regOldData for zero.
//
// For an UPDATE, the pkChng boolean is true if the true primary key (the

// might be modified by the UPDATE.  If pkChng is false, then the key of
// the iDataCur content table is guaranteed to be unchanged by the UPDATE.
//
// For an INSERT, the pkChng boolean indicates whether or not the rowid
// was explicitly specified as part of the INSERT statement.  If pkChng
// is zero, it means that the either rowid is computed automatically or
// that the table is a WITHOUT ROWID table and has no rowid.  On an INSERT,
// pkChng will only be true if the INSERT statement provides an integer
// value for either the rowid column or its INTEGER PRIMARY KEY alias.
//
// The code generated by this routine will store new index entries into
// registers identified by aRegIdx[].  No index entry is created for
// indices where aRegIdx[i]==0.  The order of indices in aRegIdx[] is
// the same as the order of indices on the linked list of indices
// at pTab->pIndex.
//
// (2019-05-07) The generated code also creates a new record for the
// main table, if pTab is a rowid table, and stores that record in the
// register identified by aRegIdx[nIdx] - in other words in the first
// entry of aRegIdx[] past the last index.  It is important that the

//
// The caller must have already opened writeable cursors on the main
// table and all applicable indices (that is to say, all indices for which
// aRegIdx[] is not zero).  iDataCur is the cursor for the main table when
// inserting or updating a rowid table, or the cursor for the PRIMARY KEY
// index when operating on a WITHOUT ROWID table.  iIdxCur is the cursor

// CHECK, and UNIQUE constraints are all checked.  If a constraint fails,
// then the appropriate action is performed.  There are five possible

//
//  Constraint type  Action       What Happens
//  ---------------  ----------   ----------------------------------------
//  any              ROLLBACK     The current transaction is rolled back and
//                                sqlite3_step() returns immediately with a
//                                return code of SQLITE_CONSTRAINT.
//
//  any              ABORT        Back out changes from the current command
//                                only (do not do a complete rollback) then
//                                cause sqlite3_step() to return immediately
//                                with SQLITE_CONSTRAINT.
//
//  any              FAIL         Sqlite3_step() returns immediately with a
//                                return code of SQLITE_CONSTRAINT.  The
//                                transaction is not rolled back and any
//                                changes to prior rows are retained.
//
//  any              IGNORE       The attempt in insert or update the current
//                                row is skipped, without throwing an error.
//                                Processing continues with the next row.
//                                (There is an immediate jump to ignoreDest.)
//
//  NOT NULL         REPLACE      The NULL value is replace by the default
//                                value for that column.  If the default value
//                                is NULL, the action is the same as ABORT.
//
//  UNIQUE           REPLACE      The other row that conflicts with the row
//                                being inserted is removed.
//
//  CHECK            REPLACE      Illegal.  The results in an exception.
//
// Which action to take is determined by the overrideError parameter.
// Or if overrideError==OE_Default, then the pParse->onError parameter
// is used.  Or if pParse->onError==OE_Default then the onError value
// for the constraint is used.

//
//   WHERE_DISTINCT_UNORDERED/WHERE_DISTINCT_NOOP:
//     Build an ephemeral table that contains all entries seen before and
//     skip entries which have been seen before.
//
//     Parameter iTab is the cursor number of an ephemeral table that must
//     be opened before the VM code generated by this routine is executed.
//     The ephemeral cursor table is queried for a record identical to the
//     record formed by the current array of registers. If one is found,
//     jump to VM address addrRepeat. Otherwise, insert a new record into
//     the ephemeral cursor and proceed.
//
//     The returned value in this case is a copy of parameter iTab.
//
//   WHERE_DISTINCT_ORDERED:
//     In this case rows are being delivered sorted order. The ephermal
//     table is not required. Instead, the current set of values
//     is compared against previous row. If they match, the new row
//     is not distinct and control jumps to VM address addrRepeat. Otherwise,
//     the VM program proceeds with processing the new row.
//
//     The returned value in this case is the register number of the first
//     in an array of registers used to store the previous result row so that
//     it can be compared to the next. The caller must ensure that this
//     register is initialized to NULL.  (The fixDistinctOpenEph() routine
//     will take care of this initialization.)
//
//   WHERE_DISTINCT_UNIQUE:
//     In this case it has already been determined that the rows are distinct.
//     No special action is required. The return value is zero.
//
// Parameter pEList is the list of expressions used to generated the
// contents of each row. It is used by this routine to determine (a)
// how many elements there are in the array of registers and (b) the
// collation sequences that should be used for the comparisons if
// eTnctType is WHERE_DISTINCT_ORDERED.

//
// The setup-query runs once to generate an initial set of rows that go
// into a Queue table.  Rows are extracted from the Queue table one by
// one.  Each row extracted from Queue is output to pDest.  Then the single
// extracted row (now in the iCurrent table) becomes the content of the
// recursive-table for a recursive-query run.  The output of the recursive-query
// is added back into the Queue table.  Then another row is extracted from Queue
// and the iteration continues until the Queue table is empty.
//
// If the compound query operator is UNION then no duplicate rows are ever
// inserted into the Queue table.  The iDistinct table keeps a copy of all rows
// that have ever been inserted into Queue and causes duplicates to be
// discarded.  If the operator is UNION ALL, then duplicates are allowed.
//
// If the query has an ORDER BY, then entries in the Queue table are kept in
// ORDER BY order and the first entry is extracted for each cycle.  Without
// an ORDER BY, the Queue table is just a FIFO.
//
// If a LIMIT clause is provided, then the iteration stops after LIMIT rows
// have been output to pDest.  A LIMIT of zero means to output no rows and a
// negative LIMIT means to output all rows.  If there is also an OFFSET clause
// with a positive value, then the first OFFSET outputs are discarded rather
// than being sent to pDest.  The LIMIT count does not begin until after OFFSET
// rows have been skipped.

//
// We assume a query of the following form:
//
//      <selectA>  <operator>  <selectB>  ORDER BY <orderbylist>
//
// <operator> is one of UNION ALL, UNION, EXCEPT, or INTERSECT.  The idea
// is to code both <selectA> and <selectB> with the ORDER BY clause as
// co-routines.  Then run the co-routines in parallel and merge the results
// into the output.  In addition to the two coroutines (called selectA and
// selectB) there are 7 subroutines:
//
//    outA:    Move the output of the selectA coroutine into the output
//             of the compound query.
//
//    outB:    Move the output of the selectB coroutine into the output
//             of the compound query.  (Only generated for UNION and
//             UNION ALL.  EXCEPT and INSERTSECT never output a row that
//             appears only in B.)
//
//    AltB:    Called when there is data from both coroutines and A<B.
//
//    AeqB:    Called when there is data from both coroutines and A==B.
//
//    AgtB:    Called when there is data from both coroutines and A>B.
//
//    EofA:    Called when data is exhausted from selectA.
//
//    EofB:    Called when data is exhausted from selectB.
//
// The implementation of the latter five subroutines depend on which
// <operator> is used:
//
//
//             UNION ALL         UNION            EXCEPT          INTERSECT
//          -------------  -----------------  --------------  -----------------
//   AltB:   outA, nextA      outA, nextA       outA, nextA         nextA
//
//   AeqB:   outA, nextA         nextA             nextA         outA, nextA
//
//   AgtB:   outB, nextB      outB, nextB          nextB            nextB
//
//   EofA:   outB, nextB      outB, nextB          halt             halt
//
//   EofB:   outA, nextA      outA, nextA       outA, nextA         halt
//
// In the AltB, AeqB, and AgtB subroutines, an EOF on A following nextA
// causes an immediate jump to EofA and an EOF on B following nextB causes
// an immediate jump to EofB.  Within EofA and EofB, and EOF on entry or
// following nextX causes a jump to the end of the select processing.
//
// Duplicate removal in the UNION, EXCEPT, and INTERSECT cases is handled
// within the output subroutine.  The regPrev register set holds the previously
// output value.  A comparison is made against this value and the output
// is skipped if the next results would be the same as the previous.
//
// The implementation plan is to implement the two coroutines and seven
// subroutines first, then put the control logic at the bottom.  Like this:
//
//          goto Init
//     coA: coroutine for left query (A)
//     coB: coroutine for right query (B)
//    outA: output one row of A
//    outB: output one row of B (UNION and UNION ALL only)
//    EofA: ...
//    EofB: ...
//    AltB: ...
//    AeqB: ...
//    AgtB: ...
//    Init: initialize coroutine registers
//          yield coA
//          if eof(A) goto EofA
//          yield coB
//          if eof(B) goto EofB
//    Cmpr: Compare A, B
//          Jump AltB, AeqB, AgtB
//     End: ...
//
// We call AltB, AeqB, AgtB, EofA, and EofB "subroutines" but they are not
// actually called using Gosub and they do not Return.  EofA and EofB loop
// until all data is exhausted then jump to the "end" labe.  AltB, AeqB,
// and AgtB jump to either L2 or to one of EofA or EofB.

// This routine attempts to flatten subqueries as a performance optimization.
// This routine returns 1 if it makes changes and 0 if no flattening occurs.
//
// To understand the concept of flattening, consider the following
// query:
//
//     SELECT a FROM (SELECT x+y AS a FROM t1 WHERE z<100) WHERE a>5
//
// The default way of implementing this query is to execute the
// subquery first and store the results in a temporary table, then
// run the outer query on that temporary table.  This requires two
// passes over the data.  Furthermore, because the temporary table
// has no indices, the WHERE clause on the outer query cannot be
// optimized.
//
// This routine attempts to rewrite queries such as the above into
// a single flat select, like this:
//
//     SELECT x+y AS a FROM t1 WHERE z<100 AND a>5
//
// The code generated for this simplification gives the same result
// but only has to scan the data once.  And because indices might
// exist on the table t1, a complete scan of the data might be
// avoided.
//
// Flattening is subject to the following constraints:
//
//  (**)  We no longer attempt to flatten aggregate subqueries. Was:
//        The subquery and the outer query cannot both be aggregates.
//
//  (**)  We no longer attempt to flatten aggregate subqueries. Was:
//        (2) If the subquery is an aggregate then
//        (2a) the outer query must not be a join and
//        (2b) the outer query must not use subqueries
//             other than the one FROM-clause subquery that is a candidate
//             for flattening.  (This is due to ticket [2f7170d73bf9abf80]
//             from 2015-02-09.)
//
//   (3)  If the subquery is the right operand of a LEFT JOIN then
//        (3a) the subquery may not be a join and
//        (3b) the FROM clause of the subquery may not contain a virtual
//             table and
//        (3c) the outer query may not be an aggregate.
//        (3d) the outer query may not be DISTINCT.
//        See also (26) for restrictions on RIGHT JOIN.
//
//   (4)  The subquery can not be DISTINCT.
//
//  (**)  At one point restrictions (4) and (5) defined a subset of DISTINCT
//        sub-queries that were excluded from this optimization. Restriction
//        (4) has since been expanded to exclude all DISTINCT subqueries.
//
//  (**)  We no longer attempt to flatten aggregate subqueries.  Was:
//        If the subquery is aggregate, the outer query may not be DISTINCT.
//
//   (7)  The subquery must have a FROM clause.  TODO:  For subqueries without
//        A FROM clause, consider adding a FROM clause with the special
//        table sqlite_once that consists of a single row containing a
//        single NULL.
//
//   (8)  If the subquery uses LIMIT then the outer query may not be a join.
//
//   (9)  If the subquery uses LIMIT then the outer query may not be aggregate.
//
//  (**)  Restriction (10) was removed from the code on 2005-02-05 but we
//        accidently carried the comment forward until 2014-09-15.  Original
//        constraint: "If the subquery is aggregate then the outer query
//        may not use LIMIT."
//
//  (11)  The subquery and the outer query may not both have ORDER BY clauses.
//
//  (**)  Not implemented.  Subsumed into restriction (3).  Was previously
//        a separate restriction deriving from ticket #350.
//
//  (13)  The subquery and outer query may not both use LIMIT.
//
//  (14)  The subquery may not use OFFSET.
//
//  (15)  If the outer query is part of a compound select, then the
//        subquery may not use LIMIT.
//        (See ticket #2339 and ticket [02a8e81d44]).
//
//  (16)  If the outer query is aggregate, then the subquery may not
//        use ORDER BY.  (Ticket #2942)  This used to not matter
//        until we introduced the group_concat() function.
//
//  (17)  If the subquery is a compound select, then
//        (17a) all compound operators must be a UNION ALL, and
//        (17b) no terms within the subquery compound may be aggregate
//              or DISTINCT, and
//        (17c) every term within the subquery compound must have a FROM clause
//        (17d) the outer query may not be
//              (17d1) aggregate, or
//              (17d2) DISTINCT
//        (17e) the subquery may not contain window functions, and
//        (17f) the subquery must not be the RHS of a LEFT JOIN.
//        (17g) either the subquery is the first element of the outer
//              query or there are no RIGHT or FULL JOINs in any arm
//              of the subquery.  (This is a duplicate of condition (27b).)
//
//        The parent and sub-query may contain WHERE clauses. Subject to
//        rules (11), (13) and (14), they may also contain ORDER BY,
//        LIMIT and OFFSET clauses.  The subquery cannot use any compound
//        operator other than UNION ALL because all the other compound
//        operators have an implied DISTINCT which is disallowed by
//        restriction (4).
//
//        Also, each component of the sub-query must return the same number
//        of result columns. This is actually a requirement for any compound
//        SELECT statement, but all the code here does is make sure that no
//        such (illegal) sub-query is flattened. The caller will detect the
//        syntax error and return a detailed message.
//
//  (18)  If the sub-query is a compound select, then all terms of the
//        ORDER BY clause of the parent must be copies of a term returned
//        by the parent query.
//
//  (19)  If the subquery uses LIMIT then the outer query may not
//        have a WHERE clause.
//
//  (20)  If the sub-query is a compound select, then it must not use
//        an ORDER BY clause.  Ticket #3773.  We could relax this constraint
//        somewhat by saying that the terms of the ORDER BY clause must
//        appear as unmodified result columns in the outer query.  But we
//        have other optimizations in mind to deal with that case.
//
//  (21)  If the subquery uses LIMIT then the outer query may not be
//        DISTINCT.  (See ticket [752e1646fc]).
//
//  (22)  The subquery may not be a recursive CTE.
//
//  (23)  If the outer query is a recursive CTE, then the sub-query may not be
//        a compound query.  This restriction is because transforming the
//        parent to a compound query confuses the code that handles
//        recursive queries in multiSelect().
//
//  (**)  We no longer attempt to flatten aggregate subqueries.  Was:
//        The subquery may not be an aggregate that uses the built-in min() or
//        or max() functions.  (Without this restriction, a query like:
//        "SELECT x FROM (SELECT max(y), x FROM t1)" would not necessarily
//        return the value X for which Y was maximal.)
//
//  (25)  If either the subquery or the parent query contains a window
//        function in the select list or ORDER BY clause, flattening
//        is not attempted.
//
//  (26)  The subquery may not be the right operand of a RIGHT JOIN.
//        See also (3) for restrictions on LEFT JOIN.
//
//  (27)  The subquery may not contain a FULL or RIGHT JOIN unless it
//        is the first element of the parent query.  This must be the
//        the case if:
//        (27a) the subquery is not compound query, and
//        (27b) the subquery is a compound query and the RIGHT JOIN occurs
//              in any arm of the compound query.  (See also (17g).)
//
//  (28)  The subquery is not a MATERIALIZED CTE.
//
//  (29)  Either the subquery is not the right-hand operand of a join with an
//        ON or USING clause nor the right-hand operand of a NATURAL JOIN, or
//        the right-most table within the FROM clause of the subquery
//        is not part of an outer join.
//
//
// In this routine, the "p" parameter is a pointer to the outer query.
// The subquery is p->pSrc->a[iFrom].  isAgg is true if the outer query
// uses aggregates.
//
// If flattening is not attempted, this routine is a no-op and returns 0.
// If flattening is attempted this routine returns 1.
//
// All of the expression analysis must occur on both the outer query and
// the subquery before this routine runs.

// If the WHERE clause contains terms of the form COLUMN=CONSTANT or
// CONSTANT=COLUMN that are top-level AND-connected terms that are not
// part of a ON clause from a LEFT JOIN, then throughout the query
// replace all other occurrences of COLUMN with CONSTANT.
//
// For example, the query:
//
//      SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=t1.a AND t3.c=t2.b
//
// Is transformed into
//
//      SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=39 AND t3.c=39
//
// Return true if any transformations where made and false if not.
//
// Implementation note:  Constant propagation is tricky due to affinity
// and collating sequence interactions.  Consider this example:
//
//    CREATE TABLE t1(a INT,b TEXT);
//    INSERT INTO t1 VALUES(123,'0123');
//    SELECT * FROM t1 WHERE a=123 AND b=a;
//    SELECT * FROM t1 WHERE a=123 AND b=123;
//
// The two SELECT statements above should return different answers.  b=a
// is alway true because the comparison uses numeric affinity, but b=123
// is false because it uses text affinity and '0123' is not the same as '123'.
// To work around this, the expression tree is not actually changed from
// "b=a" to "b=123" but rather the "a" in "b=a" is tagged with EP_FixedCol
// and the "123" value is hung off of the pLeft pointer.  Code generator
// routines know to generate the constant "123" instead of looking up the
// column value.  Also, to avoid collation problems, this optimization is
// only attempted if the "a=123" term uses the default BINARY collation.
//
// 2021-05-25 forum post 6a06202608: Another troublesome case is...
//

//
// Transformed into:
//
//    SELECT * FROM (SELECT a AS x, c-d AS y FROM t1 WHERE a=5 AND c-d=10)
//     WHERE x=5 AND y=10;
//
// The hope is that the terms added to the inner query will make it more
// efficient.
//

//
//   (1) (** This restriction was removed on 2017-09-29.  We used to
//           disallow this optimization for aggregate subqueries, but now
//           it is allowed by putting the extra terms on the HAVING clause.
//           The added HAVING clause is pointless if the subquery lacks
//           a GROUP BY clause.  But such a HAVING clause is also harmless
//           so there does not appear to be any reason to add extra logic
//           to suppress it. **)
//
//   (2) The inner query is the recursive part of a common table expression.
//
//   (3) The inner query has a LIMIT clause (since the changes to the WHERE
//       clause would change the meaning of the LIMIT).
//
//   (4) The inner query is the right operand of a LEFT JOIN and the
//       expression to be pushed down does not come from the ON clause
//       on that LEFT JOIN.
//
//   (5) The WHERE clause expression originates in the ON or USING clause
//       of a LEFT JOIN where iCursor is not the right-hand table of that
//       left join.  An example:
//
//           SELECT *
//           FROM (SELECT 1 AS a1 UNION ALL SELECT 2) AS aa
//           JOIN (SELECT 1 AS b2 UNION ALL SELECT 2) AS bb ON (a1=b2)
//           LEFT JOIN (SELECT 8 AS c3 UNION ALL SELECT 9) AS cc ON (b2=2);
//
//       The correct answer is three rows:  (1,1,NULL),(2,2,8),(2,2,9).
//       But if the (b2=2) term were to be pushed down into the bb subquery,
//       then the (1,1,NULL) row would be suppressed.
//
//   (6) Window functions make things tricky as changes to the WHERE clause
//       of the inner query could change the window over which window
//       functions are calculated. Therefore, do not attempt the optimization
//       if:
//
//     (6a) The inner query uses multiple incompatible window partitions.
//
//     (6b) The inner query is a compound and uses window-functions.
//
//     (6c) The WHERE clause does not consist entirely of constants and
//          copies of expressions found in the PARTITION BY clause of
//          all window-functions used by the sub-query. It is safe to
//          filter out entire partitions, as this does not change the
//          window over which any window-function is calculated.
//
//   (7) The inner query is a Common Table Expression (CTE) that should
//       be materialized.  (This restriction is implemented in the calling
//       routine.)
//
// Return 0 if no changes are made and non-zero if one or more WHERE clause
// terms are duplicated into the subquery.

// The VACUUM command is used to clean up the database,

//
//   (1)  Create a new transient database file
//   (2)  Copy all content from the database being vacuumed into
//        the new transient database file
//   (3)  Copy content from the transient database back into the
//        original database.
//
// The transient database requires temporary disk space approximately
// equal to the size of the original database.  The copy operation of
// step (3) requires additional temporary disk space approximately equal
// to the size of the original database for the rollback journal.
// Hence, temporary disk space that is approximately 2x the size of the
// original database is required.  Every page of the database is written
// approximately 3 times:  Once for step (2) and twice for step (3).
// Two writes per page are required in step (3) because the original
// database content must be written into the rollback journal prior to
// overwriting the database with the vacuumed content.
//
// Only 1x temporary space and only 1x writes would be required if
// the copy of step (3) were replaced by deleting the original database
// and renaming the transient database as the original.  But that will
// not work if other processes are attached to the original database.
// And a power loss in between deleting the original and renaming the
// transient would cause the database file to appear to be deleted
// following reboot.

// Disable a term in the WHERE clause.  Except, do not disable the term

//
//   (1)  SELECT * FROM t1 LEFT JOIN t2 ON t1.a=t2.x WHERE t2.z='ok'
//   (2)  SELECT * FROM t1 LEFT JOIN t2 ON t1.a=t2.x AND t2.z='ok'
//   (3)  SELECT * FROM t1, t2 WHERE t1.a=t2.x AND t2.z='ok'
//
// The t2.z='ok' is disabled in the in (2) because it originates
// in the ON clause.  The term is disabled in (3) because it is not part
// of a LEFT OUTER JOIN.  In (1), the term is not disabled.
//
// Disabling a term causes that term to not be tested in the inner loop
// of the join.  Disabling is an optimization.  When terms are satisfied
// by indices, we disable them to prevent redundant tests in the inner
// loop.  We would get the correct results if nothing were ever disabled,
// but joins might run a little slower.  The trick is to disable as much
// as we can without disabling too much.  If we disabled in (1), we'd get
// the wrong answer.  See ticket #813.
//
// If all the children of a term are disabled, then that term is also
// automatically disabled.  In this way, terms get disabled if derived
// virtual terms are tested first.  For example:
//
//      x GLOB 'abc*' AND x>='abc' AND x<'acd'
//      \___________/     \______/     \_____/
//         parent          child1       child2
//
// Only the parent term was in the original WHERE clause.  The child1
// and child2 terms were added by the LIKE optimization.  If both of
// the virtual child terms are valid, then testing of the parent can be
// skipped.
//
// Usually the parent term is marked as TERM_CODED.  But if the parent
// term was originally TERM_LIKE, then the parent gets TERM_LIKECOND instead.
// The TERM_LIKECOND marking indicates that the term should be coded inside
// a conditional such that is only evaluated on the second pass of a
// LIKE-optimization loop, when scanning BLOBs instead of strings.

// In the example above, the index on t1(a) has TEXT affinity. But since

//                          ^^^^^^^^^^^^^^^^^^^^
//
// This routine analyzes terms such as the middle term in the above example.
// A WhereOrTerm object is computed and attached to the term under
// analysis, regardless of the outcome of the analysis.  Hence:
//
//     WhereTerm.wtFlags   |=  TERM_ORINFO
//     WhereTerm.u.pOrInfo  =  a dynamically allocated WhereOrTerm object
//
// The term being analyzed must have two or more of OR-connected subterms.
// A single subterm might be a set of AND-connected sub-subterms.
// Examples of terms under analysis:
//
//     (A)     t1.x=t2.y OR t1.x=t2.z OR t1.y=15 OR t1.z=t3.a+5
//     (B)     x=expr1 OR expr2=x OR x=expr3
//     (C)     t1.x=t2.y OR (t1.x=t2.z AND t1.y=15)
//     (D)     x=expr1 OR (y>11 AND y<22 AND z LIKE '*hello*')
//     (E)     (p.a=1 AND q.b=2 AND r.c=3) OR (p.x=4 AND q.y=5 AND r.z=6)
//     (F)     x>A OR (x=A AND y>=B)
//
// CASE 1:
//
// If all subterms are of the form T.C=expr for some single column of C and
// a single table T (as shown in example B above) then create a new virtual
// term that is an equivalent IN expression.  In other words, if the term
// being analyzed is:
//
//      x = expr1  OR  expr2 = x  OR  x = expr3
//
// then create a new virtual term like this:
//
//      x IN (expr1,expr2,expr3)
//
// CASE 2:
//
// If there are exactly two disjuncts and one side has x>A and the other side
// has x=A (for the same x and A) then add a new virtual conjunct term to the
// WHERE clause of the form "x>=A".  Example:
//
//      x>A OR (x=A AND y>B)    adds:    x>=A
//
// The added conjunct can sometimes be helpful in query planning.
//
// CASE 3:
//
// If all subterms are indexable by a single table T, then set
//
//     WhereTerm.eOperator              =  WO_OR
//     WhereTerm.u.pOrInfo->indexable  |=  the cursor number for table T
//
// A subterm is "indexable" if it is of the form
// "T.C <op> <expr>" where C is any column of table T and
// <op> is one of "=", "<", "<=", ">", ">=", "IS NULL", or "IN".
// A subterm is also indexable if it is an AND of two or more
// subsubterms at least one of which is indexable.  Indexable AND
// subterms have their eOperator set to WO_AND and they have
// u.pAndInfo set to a dynamically allocated WhereAndTerm object.
//
// From another point of view, "indexable" means that the subterm could
// potentially be used with an index if an appropriate index exists.
// This analysis does not consider whether or not the index exists; that
// is decided elsewhere.  This analysis only looks at whether subterms
// appropriate for indexing exist.
//
// All examples A through E above satisfy case 3.  But if a term
// also satisfies case 1 (such as B) we know that the optimizer will
// always prefer case 1, so in that case we pretend that case 3 is not
// satisfied.
//
// It might be the case that multiple tables are indexable.  For example,
// (E) above is indexable on tables P, Q, and R.
//
// Terms that satisfy case 3 are candidates for lookup by using
// separate indices to find rowids for each subterm and composing
// the union of all rowids using a RowSet object.  This is similar
// to "bitmap indices" in other database engines.
//
// OTHERWISE:
//
// If none of cases 1, 2, or 3 apply, then leave the eOperator set to
// zero.  This term is not useful for search.

// Routines with file scope above.  Interface to the rest of the where.c

//

// This routine identifies subexpressions in the WHERE clause where
// each subexpression is separated by the AND operator or some other
// operator specified in the op parameter.  The WhereClause structure
// is filled with pointers to subexpressions.  For example:
//
//    WHERE  a=='hello' AND coalesce(b,11)<10 AND (c+12!=d OR c==22)
//           \________/     \_______________/     \________________/

//
// The original WHERE clause in pExpr is unaltered.  All this routine
// does is make slot[] entries point to substructure within pExpr.
//
// In the previous sentence and in the diagram, "slot[]" refers to
// the WhereClause.a[] array.  The slot[] array grows as needed to contain
// all terms of the WHERE clause.

// Add all WhereLoop objects for a single table of the join where the table

// a b-tree table, not a virtual table.
//
// The costs (WhereLoop.rRun) of the b-tree loops added by this function
// are calculated as follows:
//
// For a full scan, assuming the table (or index) contains nRow rows:
//
//     cost = nRow * 3.0                    // full-table scan
//     cost = nRow * K                      // scan of covering index
//     cost = nRow * (K+3.0)                // scan of non-covering index
//
// where K is a value between 1.1 and 3.0 set based on the relative
// estimated average size of the index and table records.
//
// For an index scan, where nVisit is the number of index rows visited
// by the scan, and nSeek is the number of seek operations required on
// the index b-tree:
//
//     cost = nSeek * (log(nRow) + K * nVisit)          // covering index
//     cost = nSeek * (log(nRow) + (K+3.0) * nVisit)    // non-covering index
//
// Normally, nSeek is 1. nSeek values greater than 1 come about if the
// WHERE clause includes "x IN (....)" terms used in place of "x=?". Or when
// implicit "x IN (SELECT x FROM tbl)" terms are added for skip-scans.
//
// The estimated values (nRow, nVisit, nSeek) often contain a large amount
// of uncertainty.  For this reason, scoring is designed to pick plans that
// "do the least harm" if the estimates are inaccurate.  For example, a
// log(nRow) factor is omitted from a non-covering index scan in order to
// bias the scoring in favor of using an index, since the worst-case
// performance of using an index is far better than the worst-case performance
// of a full table scan.

// Generate the beginning of the loop used for WHERE clause processing.
// The return value is a pointer to an opaque structure that contains
// information needed to terminate the loop.  Later, the calling routine
// should invoke sqlite3WhereEnd() with the return value of this function
// in order to complete the WHERE clause processing.
//
// If an error occurs, this routine returns NULL.
//
// The basic idea is to do a nested loop, one loop for each table in
// the FROM clause of a select.  (INSERT and UPDATE statements are the
// same as a SELECT with only a single table in the FROM clause.)  For
// example, if the SQL is this:
//
//       SELECT * FROM t1, t2, t3 WHERE ...;
//
// Then the code generated is conceptually like the following:
//
//      foreach row1 in t1 do       \    Code generated
//        foreach row2 in t2 do      |-- by sqlite3WhereBegin()
//          foreach row3 in t3 do   /
//            ...
//          end                     \    Code generated
//        end                        |-- by sqlite3WhereEnd()
//      end                         /
//
// Note that the loops might not be nested in the order in which they
// appear in the FROM clause if a different order is better able to make
// use of indices.  Note also that when the IN operator appears in
// the WHERE clause, it might result in additional nested loops for
// scanning through all values on the right-hand side of the IN.
//
// There are Btree cursors associated with each table.  t1 uses cursor
// number pTabList->a[0].iCursor.  t2 uses the cursor pTabList->a[1].iCursor.
// And so forth.  This routine generates code to open those VDBE cursors
// and sqlite3WhereEnd() generates the code to close them.
//
// The code that sqlite3WhereBegin() generates leaves the cursors named
// in pTabList pointing at their appropriate entries.  The [...] code
// can use OP_Column and OP_Rowid opcodes on these cursors to extract
// data from the various tables of the loop.
//
// If the WHERE clause is empty, the foreach loops must each scan their
// entire tables.  Thus a three-way join is an O(N^3) operation.  But if
// the tables have indices and there are terms in the WHERE clause that
// refer to those indices, a complete table scan can be avoided and the
// code will run much faster.  Most of the work of this routine is checking
// to see if there are indices that can be used to speed up the loop.
//
// Terms of the WHERE clause are also used to limit which rows actually
// make it to the "..." in the middle of the loop.  After each "foreach",
// terms of the WHERE clause that use only terms in that loop and outer
// loops are evaluated and if false a jump is made around all subsequent
// inner loops (or around the "..." if the test occurs within the inner-
// most loop)
//
// OUTER JOINS
//
// An outer join of tables t1 and t2 is conceptally coded as follows:
//
//    foreach row1 in t1 do
//      flag = 0
//      foreach row2 in t2 do
//        start:
//          ...
//          flag = 1
//      end
//      if flag==0 then
//        move the row2 cursor to a null row
//        goto start
//      fi
//    end
//
// ORDER BY CLAUSE PROCESSING
//
// pOrderBy is a pointer to the ORDER BY clause (or the GROUP BY clause
// if the WHERE_GROUPBY flag is set in wctrlFlags) of a SELECT statement
// if there is one.  If there is no ORDER BY clause or if this routine
// is called from an UPDATE or DELETE statement, then pOrderBy is NULL.
//
// The iIdxCur parameter is the cursor number of an index.  If
// WHERE_OR_SUBCLAUSE is set, iIdxCur is the cursor number of an index
// to use for OR clause processing.  The WHERE clause should use this
// specific cursor.  If WHERE_ONEPASS_DESIRED is set, then iIdxCur is
// the first cursor in an array of cursors for all indices.  iIdxCur should
// be used to compute the appropriate cursor depending on which index is
// used.

// #include "sqliteInt.h"

// SELECT REWRITING
//
//   Any SELECT statement that contains one or more window functions in
//   either the select list or ORDER BY clause (the only two places window
//   functions may be used) is transformed by function sqlite3WindowRewrite()
//   in order to support window function processing. For example, with the
//   schema:
//
//     CREATE TABLE t1(a, b, c, d, e, f, g);
//
//   the statement:
//
//     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM t1 ORDER BY e;
//
//   is transformed to:
//
//     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM (
//         SELECT a, e, c, d, b FROM t1 ORDER BY c, d
//     ) ORDER BY e;
//
//   The flattening optimization is disabled when processing this transformed
//   SELECT statement. This allows the implementation of the window function
//   (in this case max()) to process rows sorted in order of (c, d), which
//   makes things easier for obvious reasons. More generally:
//
//     * FROM, WHERE, GROUP BY and HAVING clauses are all moved to
//       the sub-query.
//
//     * ORDER BY, LIMIT and OFFSET remain part of the parent query.
//
//     * Terminals from each of the expression trees that make up the
//       select-list and ORDER BY expressions in the parent query are
//       selected by the sub-query. For the purposes of the transformation,
//       terminals are column references and aggregate functions.
//
//   If there is more than one window function in the SELECT that uses
//   the same window declaration (the OVER bit), then a single scan may
//   be used to process more than one window function. For example:
//
//     SELECT max(b) OVER (PARTITION BY c ORDER BY d),
//            min(e) OVER (PARTITION BY c ORDER BY d)
//     FROM t1;
//
//   is transformed in the same way as the example above. However:
//
//     SELECT max(b) OVER (PARTITION BY c ORDER BY d),
//            min(e) OVER (PARTITION BY a ORDER BY b)
//     FROM t1;
//
//   Must be transformed to:
//
//     SELECT max(b) OVER (PARTITION BY c ORDER BY d) FROM (
//         SELECT e, min(e) OVER (PARTITION BY a ORDER BY b), c, d, b FROM
//           SELECT a, e, c, d, b FROM t1 ORDER BY a, b
//         ) ORDER BY c, d
//     ) ORDER BY e;
//
//   so that both min() and max() may process rows in the order defined by
//   their respective window declarations.
//
// INTERFACE WITH SELECT.C
//
//   When processing the rewritten SELECT statement, code in select.c calls
//   sqlite3WhereBegin() to begin iterating through the results of the
//   sub-query, which is always implemented as a co-routine. It then calls
//   sqlite3WindowCodeStep() to process rows and finish the scan by calling
//   sqlite3WhereEnd().
//
//   sqlite3WindowCodeStep() generates VM code so that, for each row returned
//   by the sub-query a sub-routine (OP_Gosub) coded by select.c is invoked.
//   When the sub-routine is invoked:
//
//     * The results of all window-functions for the row are stored
//       in the associated Window.regResult registers.
//
//     * The required terminal values are stored in the current row of
//       temp table Window.iEphCsr.
//
//   In some cases, depending on the window frame and the specific window
//   functions invoked, sqlite3WindowCodeStep() caches each entire partition
//   in a temp table before returning any rows. In other cases it does not.
//   This detail is encapsulated within this file, the code generated by
//   select.c is the same in either case.
//
// BUILT-IN WINDOW FUNCTIONS
//
//   This implementation features the following built-in window functions:
//
//     row_number()
//     rank()
//     dense_rank()
//     percent_rank()
//     cume_dist()
//     ntile(N)
//     lead(expr [, offset [, default]])
//     lag(expr [, offset [, default]])
//     first_value(expr)
//     last_value(expr)
//     nth_value(expr, N)
//
//   These are the same built-in window functions supported by Postgres.
//   Although the behaviour of aggregate window functions (functions that
//   can be used as either aggregates or window funtions) allows them to
//   be implemented using an API, built-in window functions are much more
//   esoteric. Additionally, some window functions (e.g. nth_value())
//   may only be implemented by caching the entire partition in memory.
//   As such, some built-in window functions use the same API as aggregate
//   window functions and some are implemented directly using VDBE
//   instructions. Additionally, for those functions that use the API, the
//   window frame is sometimes modified before the SELECT statement is
//   rewritten. For example, regardless of the specified window frame, the
//   row_number() function always uses:
//
//     ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
//
//   See sqlite3WindowUpdate() for details.
//
//   As well as some of the built-in window functions, aggregate window
//   functions min() and max() are implemented using VDBE instructions if
//   the start of the window frame is declared as anything other than
//   UNBOUNDED PRECEDING.

// window frame has been coerced to:

//         }
//       }
//
// The pseudo-code above uses the following shorthand:
//
//   AGGSTEP:    invoke the aggregate xStep() function for each window function
//               with arguments read from the current row of cursor csrEnd, then
//               step cursor csrEnd forward one row (i.e. sqlite3BtreeNext()).
//
//   RETURN_ROW: return a row to the caller based on the contents of the
//               current row of csrCurrent and the current state of all
//               aggregates. Then step cursor csrCurrent forward one row.
//
//   AGGINVERSE: invoke the aggregate xInverse() function for each window
//               functions with arguments read from the current row of cursor
//               csrStart. Then step csrStart forward one row.
//
// There are two other ROWS window frames that are handled significantly
// differently from the above - "BETWEEN <expr> PRECEDING AND <expr> PRECEDING"
// and "BETWEEN <expr> FOLLOWING AND <expr> FOLLOWING". These are special
// cases because they change the order in which the three cursors (csrStart,
// csrCurrent and csrEnd) iterate through the ephemeral table. Cases that
// use UNBOUNDED or CURRENT ROW are much simpler variations on one of these
// three.
//
//   ROWS BETWEEN <expr1> PRECEDING AND <expr2> PRECEDING

//
// For the most part, the patterns above are adapted to support UNBOUNDED by
// assuming that it is equivalent to "infinity PRECEDING/FOLLOWING" and
// CURRENT ROW by assuming that it is equivilent to "0 PRECEDING/FOLLOWING".
// This is optimized of course - branches that will never be taken and
// conditions that are always true are omitted from the VM code. The only
// exceptional case is:
//
//   ROWS BETWEEN <expr1> FOLLOWING AND UNBOUNDED FOLLOWING
//
//     ... loop started by sqlite3WhereBegin() ...
//     if( new partition ){
//       Gosub flush

//       RETURN_ROW
//     }
//     while( !eof csrCurrent ){

//
// Also requiring special handling are the cases:
//
//   ROWS BETWEEN <expr1> PRECEDING AND <expr2> PRECEDING
//   ROWS BETWEEN <expr1> FOLLOWING AND <expr2> FOLLOWING
//
// when (expr1 < expr2). This is detected at runtime, not by this function.
// To handle this case, the pseudo-code programs depicted above are modified
// slightly to be:
//
//     ... loop started by sqlite3WhereBegin() ...
//     if( new partition ){
//       Gosub flush
//     }
//     Insert new row into eph table.
//     if( first row of partition ){
//       Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
//       regEnd = <expr2>
//       regStart = <expr1>
//       if( regEnd < regStart ){
//         RETURN_ROW
//         delete eph table contents
//         continue
//       }
//     ...
//
// The new "continue" statement in the above jumps to the next iteration
// of the outer loop - the one started by sqlite3WhereBegin().
//
// The various GROUPS cases are implemented using the same patterns as
// ROWS. The VM code is modified slightly so that:
//
//   1. The else branch in the main loop is only taken if the row just
//      added to the ephemeral table is the start of a new group. In
//      other words, it becomes:
//
//         ... loop started by sqlite3WhereBegin() ...
//         if( new partition ){
//           Gosub flush
//         }
//         Insert new row into eph table.
//         if( first row of partition ){
//           Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
//           regEnd = <expr2>
//           regStart = <expr1>
//         }else if( new group ){
//           ...
//         }
//       }
//
//   2. Instead of processing a single row, each RETURN_ROW, AGGSTEP or
//      AGGINVERSE step processes the current row of the relevant cursor and
//      all subsequent rows belonging to the same group.
//
// RANGE window frames are a little different again. As for GROUPS, the
// main loop runs once per group only. And RETURN_ROW, AGGSTEP and AGGINVERSE
// deal in groups instead of rows. As for ROWS and GROUPS, there are three
// basic cases:
//
//   RANGE BETWEEN <expr1> PRECEDING AND <expr2> FOLLOWING
//
//     ... loop started by sqlite3WhereBegin() ...
//       if( new partition ){
//         Gosub flush
//       }
//       Insert new row into eph table.
//       if( first row of partition ){
//         Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
//         regEnd = <expr2>
//         regStart = <expr1>
//       }else{
//         AGGSTEP
//         while( (csrCurrent.key + regEnd) < csrEnd.key ){
//           RETURN_ROW
//           while( csrStart.key + regStart) < csrCurrent.key ){

// various aspects of the generated parser.
//    YYCODETYPE         is the data type used to store the integer codes
//                       that represent terminal and non-terminal symbols.
//                       "unsigned char" is used if there are fewer than
//                       256 symbols.  Larger types otherwise.
//    YYNOCODE           is a number of type YYCODETYPE that is not used for
//                       any terminal or nonterminal symbol.
//    YYFALLBACK         If defined, this indicates that one or more tokens
//                       (also known as: "terminal symbols") have fall-back
//                       values which should be used if the original symbol
//                       would not parse.  This permits keywords to sometimes
//                       be used as identifiers, for example.
//    YYACTIONTYPE       is the data type used for "action codes" - numbers
//                       that indicate what to do in response to the next
//                       token.
//    sqlite3ParserTOKENTYPE     is the data type used for minor type for terminal
//                       symbols.  Background: A "minor type" is a semantic
//                       value associated with a terminal or non-terminal
//                       symbols.  For example, for an "ID" terminal symbol,
//                       the minor type might be the name of the identifier.
//                       Each non-terminal can have a different minor type.
//                       Terminal symbols all have the same minor type, though.
//                       This macros defines the minor type for terminal
//                       symbols.
//    YYMINORTYPE        is the data type used for all minor types.
//                       This is typically a union of many types, one of
//                       which is sqlite3ParserTOKENTYPE.  The entry in the union
//                       for terminal symbols is called "yy0".
//    YYSTACKDEPTH       is the maximum depth of the parser's stack.  If
//                       zero the stack is dynamically sized using realloc()
//    sqlite3ParserARG_SDECL     A static variable declaration for the %extra_argument
//    sqlite3ParserARG_PDECL     A parameter declaration for the %extra_argument
//    sqlite3ParserARG_PARAM     Code to pass %extra_argument as a subroutine parameter
//    sqlite3ParserARG_STORE     Code to store %extra_argument into yypParser
//    sqlite3ParserARG_FETCH     Code to extract %extra_argument from yypParser
//    sqlite3ParserCTX_*         As sqlite3ParserARG_ except for %extra_context
//    YYERRORSYMBOL      is the code number of the error symbol.  If not
//                       defined, then do no error processing.
//    YYNSTATE           the combined number of states.
//    YYNRULE            the number of rules in the grammar
//    YYNTOKEN           Number of terminal symbols
//    YY_MAX_SHIFT       Maximum value for shift actions
//    YY_MIN_SHIFTREDUCE Minimum value for shift-reduce actions
//    YY_MAX_SHIFTREDUCE Maximum value for shift-reduce actions

// Define the yytestcase() macro to be a no-op if is not already defined

//
// Applications can choose to define yytestcase() in the %include section
// to a macro that can assist in verifying code coverage.  For production
// code the yytestcase() macro should be turned off.  But it is useful
// for testing.

// Next are the tables used to determine what action to take based on the
// current state and lookahead token.  These tables are used to implement
// functions that take a state number and lookahead value and return an
// action integer.
//
// Suppose the action integer is N.  Then the action is determined as
// follows
//
//   0 <= N <= YY_MAX_SHIFT             Shift N.  That is, push the lookahead
//                                      token onto the stack and goto state N.
//
//   N between YY_MIN_SHIFTREDUCE       Shift to an arbitrary state then
//     and YY_MAX_SHIFTREDUCE           reduce by rule N-YY_MIN_SHIFTREDUCE.
//
//   N == YY_ERROR_ACTION               A syntax error has occurred.
//
//   N == YY_ACCEPT_ACTION              The parser accepts its input.
//
//   N == YY_NO_ACTION                  No such action.  Denotes unused
//                                      slots in the yy_action[] table.
//
//   N between YY_MIN_REDUCE            Reduce by rule N-YY_MIN_REDUCE
//     and YY_MAX_REDUCE
//
// The action table is constructed as a single large table named yy_action[].
// Given state S and lookahead X, the action is computed as either:
//
//    (A)   N = yy_action[ yy_shift_ofst[S] + X ]
//    (B)   N = yy_default[S]
//
// The (A) formula is preferred.  The B formula is used instead if
// yy_lookahead[yy_shift_ofst[S]+X] is not equal to X.
//
// The formulas above are for computing the action when the lookahead is
// a terminal symbol.  If the lookahead is a non-terminal (as occurs after
// a reduce action) then the yy_reduce_ofst[] array is used in place of
// the yy_shift_ofst[] array.
//
// The following are the tables generated in this section:
//
//  yy_action[]        A single table containing all actions.
//  yy_lookahead[]     A table containing the lookahead for each entry in
//                     yy_action.  Used to detect hash collisions.
//  yy_shift_ofst[]    For each state, the offset into yy_action for
//                     shifting terminals.
//  yy_reduce_ofst[]   For each state, the offset into yy_action for
//                     shifting non-terminals after a reduce.
//  yy_default[]       Default action for each state.

//********* End of lemon-generated parsing tables ****************************

// The next table maps tokens (terminal symbols) into fallback tokens.
// If a construct like the following:
//
//      %fallback ID X Y Z.
//
// appears in the grammar, then ID becomes a fallback token for X, Y,
// and Z.  Whenever one of the tokens X, Y, or Z is input to the parser
// but it does not parse, the type of the token is changed to ID and
// the parse is retried before an error is thrown.
//
// This feature can be used, for example, to cause some keywords in a language
// to revert to identifiers if they keyword does not apply in the context where
// it appears.

// The charMap() macro maps alphabetic characters (only) into their
// lower-case ASCII equivalent.  On ASCII machines, this is just
// an upper-to-lower case map.  On EBCDIC machines we also need
// to adjust the encoding.  The mapping is only valid for alphabetics
// which are the only characters for which this feature is used.
//
// Used by keywordhash.h

// The sqlite3KeywordCode function looks up an identifier to determine if
// it is a keyword.  If it is a keyword, the token code of that keyword is
// returned.  If the input is not a keyword, TK_ID is returned.
//
// The implementation of this routine was generated by a program,
// mkkeywordhash.c, located in the tool subdirectory of the distribution.
// The output of the mkkeywordhash.c program is written into a file
// named keywordhash.h and then included into this source file by
// the #include below.

// The code in this file implements a function that determines whether

//
// This file contains C code that implements the sqlite3_complete() API.
// This code used to be part of the tokenizer.c source file.  But by
// separating it out, the code will be automatically omitted from
// static links that do not use it.
// #include "sqliteInt.h"

// This is defined in tokenize.c.  We just have to import the definition.

// Token types used by the sqlite3_complete() routine.  See the header
// comments on that procedure for additional information.

// Return TRUE if the given SQL string ends in a semicolon.
//
// Special handling is require for CREATE TRIGGER statements.
// Whenever the CREATE TRIGGER keywords are seen, the statement
// must end with ";END;".
//
// This implementation uses a state machine with 8 states:
//
//   (0) INVALID   We have not yet seen a non-whitespace character.
//
//   (1) START     At the beginning or end of an SQL statement.  This routine
//                 returns 1 if it ends in the START state and 0 if it ends
//                 in any other state.
//
//   (2) NORMAL    We are in the middle of statement which ends with a single
//                 semicolon.
//
//   (3) EXPLAIN   The keyword EXPLAIN has been seen at the beginning of
//                 a statement.
//
//   (4) CREATE    The keyword CREATE has been seen at the beginning of a
//                 statement, possibly preceded by EXPLAIN and/or followed by
//                 TEMP or TEMPORARY
//
//   (5) TRIGGER   We are in the middle of a trigger definition that must be
//                 ended by a semicolon, the keyword END, and another semicolon.
//
//   (6) SEMI      We've seen the first semicolon in the ";END;" that occurs at
//                 the end of a trigger definition.
//
//   (7) END       We've seen the ";END" of the ";END;" that occurs at the end
//                 of a trigger definition.
//
// Transitions between states above are determined by tokens extracted
// from the input.  The following tokens are significant:
//
//   (0) tkSEMI      A semicolon.
//   (1) tkWS        Whitespace.
//   (2) tkOTHER     Any other SQL token.
//   (3) tkEXPLAIN   The "explain" keyword.
//   (4) tkCREATE    The "create" keyword.
//   (5) tkTEMP      The "temp" or "temporary" keyword.
//   (6) tkTRIGGER   The "trigger" keyword.
//   (7) tkEND       The "end" keyword.
//
// Whitespace never causes a state transition and is always ignored.
// This means that a SQL string of all whitespace is invalid.
//
// If we compile with SQLITE_OMIT_TRIGGER, all of the computation needed
// to recognize the end of a trigger can be omitted.  All we have to do
// is look for a semicolon that is not part of an string or comment.

//
// This is an SQLite module implementing full-text search.

// The code in this file is only compiled if:
//
//     * The FTS3 module is being built as an extension
//       (in which case SQLITE_CORE is not defined), or
//
//     * The FTS3 module is being built into the core of
//       SQLite (in which case SQLITE_ENABLE_FTS3 is defined).

// The full-text index is stored in a series of b+tree (-like)
// structures called segments which map terms to doclists.  The
// structures are like b+trees in layout, but are constructed from the
// bottom up in optimal fashion and are not updatable.  Since trees
// are built from the bottom up, things will be described from the
// bottom up.
//
//
// Varints ****
// The basic unit of encoding is a variable-length integer called a
// varint.  We encode variable-length integers in little-endian order
// using seven bits * per byte as follows:
//
// KEY:
//         A = 0xxxxxxx    7 bits of data and one flag bit
//         B = 1xxxxxxx    7 bits of data and one flag bit
//
//  7 bits - A
// 14 bits - BA
// 21 bits - BBA
// and so on.
//
// This is similar in concept to how sqlite encodes "varints" but
// the encoding is not the same.  SQLite varints are big-endian
// are are limited to 9 bytes in length whereas FTS3 varints are
// little-endian and can be up to 10 bytes in length (in theory).
//
// Example encodings:
//
//     1:    0x01
//   127:    0x7f
//   128:    0x81 0x00
//
//
// Document lists ****
// A doclist (document list) holds a docid-sorted list of hits for a
// given term.  Doclists hold docids and associated token positions.
// A docid is the unique integer identifier for a single document.
// A position is the index of a word within the document.  The first
// word of the document has a position of 0.
//
// FTS3 used to optionally store character offsets using a compile-time
// option.  But that functionality is no longer supported.
//
// A doclist is stored like this:
//
// array {
//   varint docid;          (delta from previous doclist)
//   array {                (position list for column 0)
//     varint position;     (2 more than the delta from previous position)
//   }
//   array {
//     varint POS_COLUMN;   (marks start of position list for new column)
//     varint column;       (index of new column)
//     array {
//       varint position;   (2 more than the delta from previous position)
//     }
//   }
//   varint POS_END;        (marks end of positions for this document.
// }
//
// Here, array { X } means zero or more occurrences of X, adjacent in
// memory.  A "position" is an index of a token in the token stream
// generated by the tokenizer. Note that POS_END and POS_COLUMN occur
// in the same logical place as the position element, and act as sentinals
// ending a position list array.  POS_END is 0.  POS_COLUMN is 1.
// The positions numbers are not stored literally but rather as two more
// than the difference from the prior position, or the just the position plus
// 2 for the first position.  Example:
//
//   label:       A B C D E  F  G H   I  J K
//   value:     123 5 9 1 1 14 35 0 234 72 0
//
// The 123 value is the first docid.  For column zero in this document
// there are two matches at positions 3 and 10 (5-2 and 9-2+3).  The 1
// at D signals the start of a new column; the 1 at E indicates that the
// new column is column number 1.  There are two positions at 12 and 45
// (14-2 and 35-2+12).  The 0 at H indicate the end-of-document.  The
// 234 at I is the delta to next docid (357).  It has one position 70
// (72-2) and then terminates with the 0 at K.
//
// A "position-list" is the list of positions for multiple columns for
// a single docid.  A "column-list" is the set of positions for a single
// column.  Hence, a position-list consists of one or more column-lists,
// a document record consists of a docid followed by a position-list and
// a doclist consists of one or more document records.
//
// A bare doclist omits the position information, becoming an
// array of varint-encoded docids.
//
// Segment leaf nodes ****
// Segment leaf nodes store terms and doclists, ordered by term.  Leaf
// nodes are written using LeafWriter, and read using LeafReader (to
// iterate through a single leaf node's data) and LeavesReader (to
// iterate through a segment's entire leaf layer).  Leaf nodes have
// the format:
//
// varint iHeight;             (height from leaf level, always 0)
// varint nTerm;               (length of first term)
// char pTerm[nTerm];          (content of first term)
// varint nDoclist;            (length of term's associated doclist)
// char pDoclist[nDoclist];    (content of doclist)
// array {
//                             (further terms are delta-encoded)
//   varint nPrefix;           (length of prefix shared with previous term)
//   varint nSuffix;           (length of unshared suffix)
//   char pTermSuffix[nSuffix];(unshared suffix of next term)
//   varint nDoclist;          (length of term's associated doclist)
//   char pDoclist[nDoclist];  (content of doclist)
// }
//
// Here, array { X } means zero or more occurrences of X, adjacent in
// memory.
//
// Leaf nodes are broken into blocks which are stored contiguously in
// the %_segments table in sorted order.  This means that when the end
// of a node is reached, the next term is in the node with the next
// greater node id.
//
// New data is spilled to a new leaf node when the current node
// exceeds LEAF_MAX bytes (default 2048).  New data which itself is
// larger than STANDALONE_MIN (default 1024) is placed in a standalone
// node (a leaf node with a single term and doclist).  The goal of
// these settings is to pack together groups of small doclists while
// making it efficient to directly access large doclists.  The
// assumption is that large doclists represent terms which are more
// likely to be query targets.
//
// TODO(shess) It may be useful for blocking decisions to be more
// dynamic.  For instance, it may make more sense to have a 2.5k leaf
// node rather than splitting into 2k and .5k nodes.  My intuition is
// that this might extend through 2x or 4x the pagesize.
//
//
// Segment interior nodes ****
// Segment interior nodes store blockids for subtree nodes and terms
// to describe what data is stored by the each subtree.  Interior
// nodes are written using InteriorWriter, and read using
// InteriorReader.  InteriorWriters are created as needed when
// SegmentWriter creates new leaf nodes, or when an interior node
// itself grows too big and must be split.  The format of interior
// nodes:
//
// varint iHeight;           (height from leaf level, always >0)
// varint iBlockid;          (block id of node's leftmost subtree)
// optional {
//   varint nTerm;           (length of first term)
//   char pTerm[nTerm];      (content of first term)
//   array {
//                                (further terms are delta-encoded)
//     varint nPrefix;            (length of shared prefix with previous term)
//     varint nSuffix;            (length of unshared suffix)
//     char pTermSuffix[nSuffix]; (unshared suffix of next term)
//   }
// }
//
// Here, optional { X } means an optional element, while array { X }
// means zero or more occurrences of X, adjacent in memory.
//
// An interior node encodes n terms separating n+1 subtrees.  The
// subtree blocks are contiguous, so only the first subtree's blockid
// is encoded.  The subtree at iBlockid will contain all terms less
// than the first term encoded (or all terms if no term is encoded).
// Otherwise, for terms greater than or equal to pTerm[i] but less
// than pTerm[i+1], the subtree for that term will be rooted at
// iBlockid+i.  Interior nodes only store enough term data to
// distinguish adjacent children (if the rightmost term of the left
// child is "something", and the leftmost term of the right child is
// "wicked", only "w" is stored).
//
// New data is spilled to a new interior node at the same height when
// the current node exceeds INTERIOR_MAX bytes (default 2048).
// INTERIOR_MIN_TERMS (default 7) keeps large terms from monopolizing
// interior nodes and making the tree too skinny.  The interior nodes
// at a given height are naturally tracked by interior nodes at
// height+1, and so on.
//
//
// Segment directory ****
// The segment directory in table %_segdir stores meta-information for
// merging and deleting segments, and also the root node of the
// segment's tree.
//
// The root node is the top node of the segment's tree after encoding
// the entire segment, restricted to ROOT_MAX bytes (default 1024).
// This could be either a leaf node or an interior node.  If the top
// node requires more than ROOT_MAX bytes, it is flushed to %_segments
// and a new root interior node is generated (which should always fit
// within ROOT_MAX because it only needs space for 2 varints, the
// height and the blockid of the previous root).
//
// The meta-information in the segment directory is:
//   level               - segment level (see below)
//   idx                 - index within level
//                       - (level,idx uniquely identify a segment)
//   start_block         - first leaf node
//   leaves_end_block    - last leaf node
//   end_block           - last block (including interior nodes)
//   root                - contents of root node
//
// If the root node is a leaf node, then start_block,
// leaves_end_block, and end_block are all 0.
//
//
// Segment merging ****
// To amortize update costs, segments are grouped into levels and
// merged in batches.  Each increase in level represents exponentially
// more documents.
//
// New documents (actually, document updates) are tokenized and
// written individually (using LeafWriter) to a level 0 segment, with
// incrementing idx.  When idx reaches MERGE_COUNT (default 16), all
// level 0 segments are merged into a single level 1 segment.  Level 1
// is populated like level 0, and eventually MERGE_COUNT level 1
// segments are merged to a single level 2 segment (representing
// MERGE_COUNT^2 updates), and so on.
//
// A segment merge traverses all segments at a given level in
// parallel, performing a straightforward sorted merge.  Since segment
// leaf nodes are written in to the %_segments table in order, this
// merge traverses the underlying sqlite disk structures efficiently.
// After the merge, all segment blocks from the merged level are
// deleted.
//
// MERGE_COUNT controls how often we merge segments.  16 seems to be
// somewhat of a sweet spot for insertion performance.  32 and 64 show
// very similar performance numbers to 16 on insertion, though they're
// a tiny bit slower (perhaps due to more overhead in merge-time
// sorting).  8 is about 20% slower than 16, 4 about 50% slower than
// 16, 2 about 66% slower than 16.
//
// At query time, high MERGE_COUNT increases the number of segments
// which need to be scanned and merged.  For instance, with 100k docs
// inserted:
//
//    MERGE_COUNT   segments
//       16           25
//        8           12
//        4           10
//        2            6
//
// This appears to have only a moderate impact on queries for very
// frequent terms (which are somewhat dominated by segment merge
// costs), and infrequent and non-existent terms still seem to be fast
// even with many segments.
//
// TODO(shess) That said, it would be nice to have a better query-side
// argument for MERGE_COUNT of 16.  Also, it is possible/likely that
// optimizations to things like doclist merging will swing the sweet
// spot around.
//
//
//
// Handling of deletions and updates ****
// Since we're using a segmented structure, with no docid-oriented
// index into the term index, we clearly cannot simply update the term
// index when a document is deleted or updated.  For deletions, we
// write an empty doclist (varint(docid) varint(POS_END)), for updates
// we simply write the new doclist.  Segment merges overwrite older
// data for a particular docid with newer data, so deletes or updates
// will eventually overtake the earlier data and knock it out.  The
// query logic likewise merges doclists so that newer data knocks out
// older data.

//
// OVERVIEW
//
//  The RBU extension requires that the RBU update be packaged as an
//  SQLite database. The tables it expects to find are described in
//  sqlite3rbu.h.  Essentially, for each table xyz in the target database
//  that the user wishes to write to, a corresponding data_xyz table is
//  created in the RBU database and populated with one row for each row to
//  update, insert or delete from the target table.
//
//  The update proceeds in three stages:
//
//  1) The database is updated. The modified database pages are written
//     to a *-oal file. A *-oal file is just like a *-wal file, except
//     that it is named "<database>-oal" instead of "<database>-wal".
//     Because regular SQLite clients do not look for file named
//     "<database>-oal", they go on using the original database in
//     rollback mode while the *-oal file is being generated.
//
//     During this stage RBU does not update the database by writing
//     directly to the target tables. Instead it creates "imposter"
//     tables using the SQLITE_TESTCTRL_IMPOSTER interface that it uses
//     to update each b-tree individually. All updates required by each
//     b-tree are completed before moving on to the next, and all
//     updates are done in sorted key order.
//
//  2) The "<database>-oal" file is moved to the equivalent "<database>-wal"
//     location using a call to rename(2). Before doing this the RBU
//     module takes an EXCLUSIVE lock on the database file, ensuring
//     that there are no other active readers.
//
//     Once the EXCLUSIVE lock is released, any other database readers
//     detect the new *-wal file and read the database in wal mode. At
//     this point they see the new version of the database - including
//     the updates made as part of the RBU update.
//
//  3) The new *-wal file is checkpointed. This proceeds in the same way
//     as a regular database checkpoint, except that a single frame is
//     checkpointed each time sqlite3rbu_step() is called. If the RBU
//     handle is closed before the entire *-wal file is checkpointed,
//     the checkpoint progress is saved in the RBU database and the
//     checkpoint can be resumed by another RBU client at some point in
//     the future.
//
// POTENTIAL PROBLEMS
//
//  The rename() call might not be portable. And RBU is not currently
//  syncing the directory after renaming the file.
//
//  When state is saved, any commit to the *-oal file and the commit to
//  the RBU update database are not atomic. So if the power fails at the
//  wrong moment they might get out of sync. As the main database will be
//  committed before the RBU update database this will likely either just
//  pass unnoticed, or result in SQLITE_CONSTRAINT errors (due to UNIQUE
//  constraint violations).
//
//  If some client does modify the target database mid RBU update, or some
//  other error occurs, the RBU extension will keep throwing errors. It's
//  not really clear how to get out of this state. The system could just
//  by delete the RBU update database and *-oal file and have the device
//  download the update again and start over.
//
//  At present, for an UPDATE, both the new.* and old.* records are
//  collected in the rbu_xyz table. And for both UPDATEs and DELETEs all
//  fields are collected.  This means we're probably writing a lot more
//  data to disk when saving the state of an ongoing update to the RBU
//  update database than is strictly necessary.

// SUMMARY
//
// Writing a transaction containing a large number of operations on
// b-tree indexes that are collectively larger than the available cache
// memory can be very inefficient.
//
// The problem is that in order to update a b-tree, the leaf page (at least)
// containing the entry being inserted or deleted must be modified. If the
// working set of leaves is larger than the available cache memory, then a
// single leaf that is modified more than once as part of the transaction
// may be loaded from or written to the persistent media multiple times.
// Additionally, because the index updates are likely to be applied in
// random order, access to pages within the database is also likely to be in
// random order, which is itself quite inefficient.
//
// One way to improve the situation is to sort the operations on each index
// by index key before applying them to the b-tree. This leads to an IO
// pattern that resembles a single linear scan through the index b-tree,
// and all but guarantees each modified leaf page is loaded and stored
// exactly once. SQLite uses this trick to improve the performance of
// CREATE INDEX commands. This extension allows it to be used to improve
// the performance of large transactions on existing databases.
//
// Additionally, this extension allows the work involved in writing the
// large transaction to be broken down into sub-transactions performed
// sequentially by separate processes. This is useful if the system cannot
// guarantee that a single update process will run for long enough to apply
// the entire update, for example because the update is being applied on a
// mobile device that is frequently rebooted. Even after the writer process
// has committed one or more sub-transactions, other database clients continue
// to read from the original database snapshot. In other words, partially
// applied transactions are not visible to other clients.
//
// "RBU" stands for "Resumable Bulk Update". As in a large database update
// transmitted via a wireless network to a mobile device. A transaction
// applied using this extension is hence refered to as an "RBU update".
//
//
// LIMITATIONS
//
// An "RBU update" transaction is subject to the following limitations:
//
//   * The transaction must consist of INSERT, UPDATE and DELETE operations
//     only.
//
//   * INSERT statements may not use any default values.
//
//   * UPDATE and DELETE statements must identify their target rows by
//     non-NULL PRIMARY KEY values. Rows with NULL values stored in PRIMARY
//     KEY fields may not be updated or deleted. If the table being written
//     has no PRIMARY KEY, affected rows must be identified by rowid.
//
//   * UPDATE statements may not modify PRIMARY KEY columns.
//
//   * No triggers will be fired.
//
//   * No foreign key violations are detected or reported.
//
//   * CHECK constraints are not enforced.
//
//   * No constraint handling mode except for "OR ROLLBACK" is supported.
//
//
// PREPARATION
//
// An "RBU update" is stored as a separate SQLite database. A database
// containing an RBU update is an "RBU database". For each table in the
// target database to be updated, the RBU database should contain a table
// named "data_<target name>" containing the same set of columns as the
// target table, and one more - "rbu_control". The data_% table should
// have no PRIMARY KEY or UNIQUE constraints, but each column should have
// the same type as the corresponding column in the target database.
// The "rbu_control" column should have no type at all. For example, if
// the target database contains:
//
//   CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c UNIQUE);
//
// Then the RBU database should contain:
//
//   CREATE TABLE data_t1(a INTEGER, b TEXT, c, rbu_control);
//
// The order of the columns in the data_% table does not matter.
//
// Instead of a regular table, the RBU database may also contain virtual
// tables or view named using the data_<target> naming scheme.
//
// Instead of the plain data_<target> naming scheme, RBU database tables
// may also be named data<integer>_<target>, where <integer> is any sequence
// of zero or more numeric characters (0-9). This can be significant because
// tables within the RBU database are always processed in order sorted by
// name. By judicious selection of the <integer> portion of the names
// of the RBU tables the user can therefore control the order in which they
// are processed. This can be useful, for example, to ensure that "external
// content" FTS4 tables are updated before their underlying content tables.
//
// If the target database table is a virtual table or a table that has no
// PRIMARY KEY declaration, the data_% table must also contain a column
// named "rbu_rowid". This column is mapped to the tables implicit primary
// key column - "rowid". Virtual tables for which the "rowid" column does
// not function like a primary key value cannot be updated using RBU. For
// example, if the target db contains either of the following:
//
//   CREATE VIRTUAL TABLE x1 USING fts3(a, b);
//   CREATE TABLE x1(a, b)
//
// then the RBU database should contain:
//
//   CREATE TABLE data_x1(a, b, rbu_rowid, rbu_control);
//
// All non-hidden columns (i.e. all columns matched by "SELECT *") of the
// target table must be present in the input table. For virtual tables,
// hidden columns are optional - they are updated by RBU if present in
// the input table, or not otherwise. For example, to write to an fts4
// table with a hidden languageid column such as:
//
//   CREATE VIRTUAL TABLE ft1 USING fts4(a, b, languageid='langid');
//
// Either of the following input table schemas may be used:
//
//   CREATE TABLE data_ft1(a, b, langid, rbu_rowid, rbu_control);
//   CREATE TABLE data_ft1(a, b, rbu_rowid, rbu_control);
//
// For each row to INSERT into the target database as part of the RBU
// update, the corresponding data_% table should contain a single record
// with the "rbu_control" column set to contain integer value 0. The
// other columns should be set to the values that make up the new record
// to insert.
//
// If the target database table has an INTEGER PRIMARY KEY, it is not
// possible to insert a NULL value into the IPK column. Attempting to
// do so results in an SQLITE_MISMATCH error.
//
// For each row to DELETE from the target database as part of the RBU
// update, the corresponding data_% table should contain a single record
// with the "rbu_control" column set to contain integer value 1. The
// real primary key values of the row to delete should be stored in the
// corresponding columns of the data_% table. The values stored in the
// other columns are not used.
//
// For each row to UPDATE from the target database as part of the RBU
// update, the corresponding data_% table should contain a single record
// with the "rbu_control" column set to contain a value of type text.
// The real primary key values identifying the row to update should be
// stored in the corresponding columns of the data_% table row, as should
// the new values of all columns being update. The text value in the
// "rbu_control" column must contain the same number of characters as
// there are columns in the target database table, and must consist entirely
// of 'x' and '.' characters (or in some special cases 'd' - see below). For
// each column that is being updated, the corresponding character is set to
// 'x'. For those that remain as they are, the corresponding character of the
// rbu_control value should be set to '.'. For example, given the tables
// above, the update statement:
//
//   UPDATE t1 SET c = 'usa' WHERE a = 4;
//
// is represented by the data_t1 row created by:
//
//   INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..x');
//
// Instead of an 'x' character, characters of the rbu_control value specified
// for UPDATEs may also be set to 'd'. In this case, instead of updating the
// target table with the value stored in the corresponding data_% column, the
// user-defined SQL function "rbu_delta()" is invoked and the result stored in
// the target table column. rbu_delta() is invoked with two arguments - the
// original value currently stored in the target table column and the
// value specified in the data_xxx table.
//
// For example, this row:
//
//   INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..d');
//
// is similar to an UPDATE statement such as:
//
//   UPDATE t1 SET c = rbu_delta(c, 'usa') WHERE a = 4;
//
// Finally, if an 'f' character appears in place of a 'd' or 's' in an
// ota_control string, the contents of the data_xxx table column is assumed
// to be a "fossil delta" - a patch to be applied to a blob value in the
// format used by the fossil source-code management system. In this case
// the existing value within the target database table must be of type BLOB.
// It is replaced by the result of applying the specified fossil delta to
// itself.
//
// If the target database table is a virtual table or a table with no PRIMARY
// KEY, the rbu_control value should not include a character corresponding
// to the rbu_rowid value. For example, this:
//
//   INSERT INTO data_ft1(a, b, rbu_rowid, rbu_control)
//       VALUES(NULL, 'usa', 12, '.x');
//
// causes a result similar to:
//
//   UPDATE ft1 SET b = 'usa' WHERE rowid = 12;
//
// The data_xxx tables themselves should have no PRIMARY KEY declarations.
// However, RBU is more efficient if reading the rows in from each data_xxx
// table in "rowid" order is roughly the same as reading them sorted by
// the PRIMARY KEY of the corresponding target database table. In other
// words, rows should be sorted using the destination table PRIMARY KEY
// fields before they are inserted into the data_xxx tables.
//
// USAGE
//
// The API declared below allows an application to apply an RBU update
// stored on disk to an existing target database. Essentially, the
// application:
//
//     1) Opens an RBU handle using the sqlite3rbu_open() function.
//
//     2) Registers any required virtual table modules with the database
//        handle returned by sqlite3rbu_db(). Also, if required, register
//        the rbu_delta() implementation.
//
//     3) Calls the sqlite3rbu_step() function one or more times on
//        the new handle. Each call to sqlite3rbu_step() performs a single
//        b-tree operation, so thousands of calls may be required to apply
//        a complete update.
//
//     4) Calls sqlite3rbu_close() to close the RBU update handle. If
//        sqlite3rbu_step() has been called enough times to completely
//        apply the update to the target database, then the RBU database
//        is marked as fully applied. Otherwise, the state of the RBU
//        update application is saved in the RBU database for later
//        resumption.
//
// See comments below for more detail on APIs.
//
// If an update is only partially applied to the target database by the

//
// OVERVIEW
//
//  The RBU extension requires that the RBU update be packaged as an
//  SQLite database. The tables it expects to find are described in
//  sqlite3rbu.h.  Essentially, for each table xyz in the target database
//  that the user wishes to write to, a corresponding data_xyz table is
//  created in the RBU database and populated with one row for each row to
//  update, insert or delete from the target table.
//
//  The update proceeds in three stages:
//
//  1) The database is updated. The modified database pages are written
//     to a *-oal file. A *-oal file is just like a *-wal file, except
//     that it is named "<database>-oal" instead of "<database>-wal".
//     Because regular SQLite clients do not look for file named
//     "<database>-oal", they go on using the original database in
//     rollback mode while the *-oal file is being generated.
//
//     During this stage RBU does not update the database by writing
//     directly to the target tables. Instead it creates "imposter"
//     tables using the SQLITE_TESTCTRL_IMPOSTER interface that it uses
//     to update each b-tree individually. All updates required by each
//     b-tree are completed before moving on to the next, and all
//     updates are done in sorted key order.
//
//  2) The "<database>-oal" file is moved to the equivalent "<database>-wal"
//     location using a call to rename(2). Before doing this the RBU
//     module takes an EXCLUSIVE lock on the database file, ensuring
//     that there are no other active readers.
//
//     Once the EXCLUSIVE lock is released, any other database readers
//     detect the new *-wal file and read the database in wal mode. At
//     this point they see the new version of the database - including
//     the updates made as part of the RBU update.
//
//  3) The new *-wal file is checkpointed. This proceeds in the same way
//     as a regular database checkpoint, except that a single frame is
//     checkpointed each time sqlite3rbu_step() is called. If the RBU
//     handle is closed before the entire *-wal file is checkpointed,
//     the checkpoint progress is saved in the RBU database and the
//     checkpoint can be resumed by another RBU client at some point in
//     the future.
//
// POTENTIAL PROBLEMS
//
//  The rename() call might not be portable. And RBU is not currently
//  syncing the directory after renaming the file.
//
//  When state is saved, any commit to the *-oal file and the commit to
//  the RBU update database are not atomic. So if the power fails at the
//  wrong moment they might get out of sync. As the main database will be
//  committed before the RBU update database this will likely either just
//  pass unnoticed, or result in SQLITE_CONSTRAINT errors (due to UNIQUE
//  constraint violations).
//
//  If some client does modify the target database mid RBU update, or some
//  other error occurs, the RBU extension will keep throwing errors. It's
//  not really clear how to get out of this state. The system could just
//  by delete the RBU update database and *-oal file and have the device
//  download the update again and start over.
//
//  At present, for an UPDATE, both the new.* and old.* records are
//  collected in the rbu_xyz table. And for both UPDATEs and DELETEs all
//  fields are collected.  This means we're probably writing a lot more
//  data to disk when saving the state of an ongoing update to the RBU
//  update database than is strictly necessary.

// SUMMARY
//
// Writing a transaction containing a large number of operations on
// b-tree indexes that are collectively larger than the available cache
// memory can be very inefficient.
//
// The problem is that in order to update a b-tree, the leaf page (at least)
// containing the entry being inserted or deleted must be modified. If the
// working set of leaves is larger than the available cache memory, then a
// single leaf that is modified more than once as part of the transaction
// may be loaded from or written to the persistent media multiple times.
// Additionally, because the index updates are likely to be applied in
// random order, access to pages within the database is also likely to be in
// random order, which is itself quite inefficient.
//
// One way to improve the situation is to sort the operations on each index
// by index key before applying them to the b-tree. This leads to an IO
// pattern that resembles a single linear scan through the index b-tree,
// and all but guarantees each modified leaf page is loaded and stored
// exactly once. SQLite uses this trick to improve the performance of
// CREATE INDEX commands. This extension allows it to be used to improve
// the performance of large transactions on existing databases.
//
// Additionally, this extension allows the work involved in writing the
// large transaction to be broken down into sub-transactions performed
// sequentially by separate processes. This is useful if the system cannot
// guarantee that a single update process will run for long enough to apply
// the entire update, for example because the update is being applied on a
// mobile device that is frequently rebooted. Even after the writer process
// has committed one or more sub-transactions, other database clients continue
// to read from the original database snapshot. In other words, partially
// applied transactions are not visible to other clients.
//
// "RBU" stands for "Resumable Bulk Update". As in a large database update
// transmitted via a wireless network to a mobile device. A transaction
// applied using this extension is hence refered to as an "RBU update".
//
//
// LIMITATIONS
//
// An "RBU update" transaction is subject to the following limitations:
//
//   * The transaction must consist of INSERT, UPDATE and DELETE operations
//     only.
//
//   * INSERT statements may not use any default values.
//
//   * UPDATE and DELETE statements must identify their target rows by
//     non-NULL PRIMARY KEY values. Rows with NULL values stored in PRIMARY
//     KEY fields may not be updated or deleted. If the table being written
//     has no PRIMARY KEY, affected rows must be identified by rowid.
//
//   * UPDATE statements may not modify PRIMARY KEY columns.
//
//   * No triggers will be fired.
//
//   * No foreign key violations are detected or reported.
//
//   * CHECK constraints are not enforced.
//
//   * No constraint handling mode except for "OR ROLLBACK" is supported.
//
//
// PREPARATION
//
// An "RBU update" is stored as a separate SQLite database. A database
// containing an RBU update is an "RBU database". For each table in the
// target database to be updated, the RBU database should contain a table
// named "data_<target name>" containing the same set of columns as the
// target table, and one more - "rbu_control". The data_% table should
// have no PRIMARY KEY or UNIQUE constraints, but each column should have
// the same type as the corresponding column in the target database.
// The "rbu_control" column should have no type at all. For example, if
// the target database contains:
//
//   CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c UNIQUE);
//
// Then the RBU database should contain:
//
//   CREATE TABLE data_t1(a INTEGER, b TEXT, c, rbu_control);
//
// The order of the columns in the data_% table does not matter.
//
// Instead of a regular table, the RBU database may also contain virtual
// tables or view named using the data_<target> naming scheme.
//
// Instead of the plain data_<target> naming scheme, RBU database tables
// may also be named data<integer>_<target>, where <integer> is any sequence
// of zero or more numeric characters (0-9). This can be significant because
// tables within the RBU database are always processed in order sorted by
// name. By judicious selection of the <integer> portion of the names
// of the RBU tables the user can therefore control the order in which they
// are processed. This can be useful, for example, to ensure that "external
// content" FTS4 tables are updated before their underlying content tables.
//
// If the target database table is a virtual table or a table that has no
// PRIMARY KEY declaration, the data_% table must also contain a column
// named "rbu_rowid". This column is mapped to the tables implicit primary
// key column - "rowid". Virtual tables for which the "rowid" column does
// not function like a primary key value cannot be updated using RBU. For
// example, if the target db contains either of the following:
//
//   CREATE VIRTUAL TABLE x1 USING fts3(a, b);
//   CREATE TABLE x1(a, b)
//
// then the RBU database should contain:
//
//   CREATE TABLE data_x1(a, b, rbu_rowid, rbu_control);
//
// All non-hidden columns (i.e. all columns matched by "SELECT *") of the
// target table must be present in the input table. For virtual tables,
// hidden columns are optional - they are updated by RBU if present in
// the input table, or not otherwise. For example, to write to an fts4
// table with a hidden languageid column such as:
//
//   CREATE VIRTUAL TABLE ft1 USING fts4(a, b, languageid='langid');
//
// Either of the following input table schemas may be used:
//
//   CREATE TABLE data_ft1(a, b, langid, rbu_rowid, rbu_control);
//   CREATE TABLE data_ft1(a, b, rbu_rowid, rbu_control);
//
// For each row to INSERT into the target database as part of the RBU
// update, the corresponding data_% table should contain a single record
// with the "rbu_control" column set to contain integer value 0. The
// other columns should be set to the values that make up the new record
// to insert.
//
// If the target database table has an INTEGER PRIMARY KEY, it is not
// possible to insert a NULL value into the IPK column. Attempting to
// do so results in an SQLITE_MISMATCH error.
//
// For each row to DELETE from the target database as part of the RBU
// update, the corresponding data_% table should contain a single record
// with the "rbu_control" column set to contain integer value 1. The
// real primary key values of the row to delete should be stored in the
// corresponding columns of the data_% table. The values stored in the
// other columns are not used.
//
// For each row to UPDATE from the target database as part of the RBU
// update, the corresponding data_% table should contain a single record
// with the "rbu_control" column set to contain a value of type text.
// The real primary key values identifying the row to update should be
// stored in the corresponding columns of the data_% table row, as should
// the new values of all columns being update. The text value in the
// "rbu_control" column must contain the same number of characters as
// there are columns in the target database table, and must consist entirely
// of 'x' and '.' characters (or in some special cases 'd' - see below). For
// each column that is being updated, the corresponding character is set to
// 'x'. For those that remain as they are, the corresponding character of the
// rbu_control value should be set to '.'. For example, given the tables
// above, the update statement:
//
//   UPDATE t1 SET c = 'usa' WHERE a = 4;
//
// is represented by the data_t1 row created by:
//
//   INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..x');
//
// Instead of an 'x' character, characters of the rbu_control value specified
// for UPDATEs may also be set to 'd'. In this case, instead of updating the
// target table with the value stored in the corresponding data_% column, the
// user-defined SQL function "rbu_delta()" is invoked and the result stored in
// the target table column. rbu_delta() is invoked with two arguments - the
// original value currently stored in the target table column and the
// value specified in the data_xxx table.
//
// For example, this row:
//
//   INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..d');
//
// is similar to an UPDATE statement such as:
//
//   UPDATE t1 SET c = rbu_delta(c, 'usa') WHERE a = 4;
//
// Finally, if an 'f' character appears in place of a 'd' or 's' in an
// ota_control string, the contents of the data_xxx table column is assumed
// to be a "fossil delta" - a patch to be applied to a blob value in the
// format used by the fossil source-code management system. In this case
// the existing value within the target database table must be of type BLOB.
// It is replaced by the result of applying the specified fossil delta to
// itself.
//
// If the target database table is a virtual table or a table with no PRIMARY
// KEY, the rbu_control value should not include a character corresponding
// to the rbu_rowid value. For example, this:
//
//   INSERT INTO data_ft1(a, b, rbu_rowid, rbu_control)
//       VALUES(NULL, 'usa', 12, '.x');
//
// causes a result similar to:
//
//   UPDATE ft1 SET b = 'usa' WHERE rowid = 12;
//
// The data_xxx tables themselves should have no PRIMARY KEY declarations.
// However, RBU is more efficient if reading the rows in from each data_xxx
// table in "rowid" order is roughly the same as reading them sorted by
// the PRIMARY KEY of the corresponding target database table. In other

// *************************************************************************
//
// Beginning of RBU VFS shim methods. The VFS shim modifies the behaviour
// of a standard VFS in the following ways:
//
// 1. Whenever the first page of a main database file is read or
//    written, the value of the change-counter cookie is stored in
//    rbu_file.iCookie. Similarly, the value of the "write-version"
//    database header field is stored in rbu_file.iWriteVer. This ensures
//    that the values are always trustworthy within an open transaction.
//
// 2. Whenever an SQLITE_OPEN_WAL file is opened, the (rbu_file.pWalFd)
//    member variable of the associated database file descriptor is set
//    to point to the new file. A mutex protected linked list of all main
//    db fds opened using a particular RBU VFS is maintained at
//    rbu_vfs.pMain to facilitate this.
//
// 3. Using a new file-control "SQLITE_FCNTL_RBU", a main db rbu_file
//    object can be marked as the target database of an RBU update. This
//    turns on the following extra special behaviour:
//
// 3a. If xAccess() is called to check if there exists a *-wal file
//     associated with an RBU target database currently in RBU_STAGE_OAL
//     stage (preparing the *-oal file), the following special handling
//     applies:
//
//      * if the *-wal file does exist, return SQLITE_CANTOPEN. An RBU
//        target database may not be in wal mode already.
//
//      * if the *-wal file does not exist, set the output parameter to
//        non-zero (to tell SQLite that it does exist) anyway.
//
//     Then, when xOpen() is called to open the *-wal file associated with
//     the RBU target in RBU_STAGE_OAL stage, instead of opening the *-wal
//     file, the rbu vfs opens the corresponding *-oal file instead.
//
// 3b. The *-shm pages returned by xShmMap() for a target db file in
//     RBU_STAGE_OAL mode are actually stored in heap memory. This is to
//     avoid creating a *-shm file on disk. Additionally, xShmLock() calls
//     are no-ops on target database files in RBU_STAGE_OAL mode. This is
//     because assert() statements in some VFS implementations fail if
//     xShmLock() is called before xShmMap().
//
// 3c. If an EXCLUSIVE lock is attempted on a target database file in any
//     mode except RBU_STAGE_DONE (all work completed and checkpointed), it
//     fails with an SQLITE_BUSY error. This is to stop RBU connections
//     from automatically checkpointing a *-wal (or *-oal) file from within
//     sqlite3_close().
//
// 3d. In RBU_STAGE_CAPTURE mode, all xRead() calls on the wal file, and
//     all xWrite() calls on the target database file perform no IO.
//     Instead the frame and page numbers that would be read and written
//     are recorded. Additionally, successful attempts to obtain exclusive
//     xShmLock() WRITER, CHECKPOINTER and READ0 locks on the target
//     database file are recorded. xShmLock() calls to unlock the same
//     locks are no-ops (so that once obtained, these locks are never
//     relinquished). Finally, calls to xSync() on the target database
//     file fail with SQLITE_INTERNAL errors.

//
// This file contains an implementation of the "dbstat" virtual table.
//
// The dbstat virtual table is used to extract low-level storage
// information from an SQLite database in order to implement the
// "sqlite3_analyzer" utility.  See the ../tool/spaceanal.tcl script
// for an example implementation.
//
// Additional information is available on the "dbstat.html" page of the
// official SQLite documentation.

// #include "sqliteInt.h"   ** Requires access to internal data structures **

// The pager and btree modules arrange objects in memory so that there are
// always approximately 200 bytes of addressable memory following each page
// buffer. This way small buffer overreads caused by corrupt database pages
// do not cause undefined behaviour. This module pads each page buffer
// by the following number of bytes for the same purpose.

// Page paths:
//
//   The value of the 'path' column describes the path taken from the
//   root-node of the b-tree structure to each page. The value of the
//   root-node path is '/'.
//
//   The value of the path for the left-most child page of the root of
//   a b-tree is '/000/'. (Btrees store content ordered from left to right
//   so the pages to the left have smaller keys than the pages to the right.)
//   The next to left-most child of the root page is
//   '/001', and so on, each sibling page identified by a 3-digit hex
//   value. The children of the 451st left-most sibling have paths such
//   as '/1c2/000/, '/1c2/001/' etc.
//
//   Overflow pages are specified by appending a '+' character and a
//   six-digit hexadecimal value to the path to the cell they are linked
//   from. For example, the three overflow pages in a chain linked from
//   the left-most cell of the 450th child of the root page are identified
//   by the paths:
//
//      '/1c2/000+000000'         // First page in overflow chain
//      '/1c2/000+000001'         // Second page in overflow chain
//      '/1c2/000+000002'         // Third page in overflow chain
//
//   If the paths are sorted using the BINARY collation sequence, then
//   the overflow pages associated with a cell will appear earlier in the
//   sort-order than its child page:
//
//      '/1c2/000/'               // Left-most child of 451st child of root

//    fts5YYCODETYPE         is the data type used to store the integer codes
//                       that represent terminal and non-terminal symbols.
//                       "unsigned char" is used if there are fewer than
//                       256 symbols.  Larger types otherwise.
//    fts5YYNOCODE           is a number of type fts5YYCODETYPE that is not used for
//                       any terminal or nonterminal symbol.
//    fts5YYFALLBACK         If defined, this indicates that one or more tokens
//                       (also known as: "terminal symbols") have fall-back
//                       values which should be used if the original symbol
//                       would not parse.  This permits keywords to sometimes
//                       be used as identifiers, for example.
//    fts5YYACTIONTYPE       is the data type used for "action codes" - numbers
//                       that indicate what to do in response to the next
//                       token.
//    sqlite3Fts5ParserFTS5TOKENTYPE     is the data type used for minor type for terminal
//                       symbols.  Background: A "minor type" is a semantic
//                       value associated with a terminal or non-terminal
//                       symbols.  For example, for an "ID" terminal symbol,
//                       the minor type might be the name of the identifier.
//                       Each non-terminal can have a different minor type.
//                       Terminal symbols all have the same minor type, though.
//                       This macros defines the minor type for terminal
//                       symbols.
//    fts5YYMINORTYPE        is the data type used for all minor types.
//                       This is typically a union of many types, one of
//                       which is sqlite3Fts5ParserFTS5TOKENTYPE.  The entry in the union
//                       for terminal symbols is called "fts5yy0".
//    fts5YYSTACKDEPTH       is the maximum depth of the parser's stack.  If
//                       zero the stack is dynamically sized using realloc()

// Define the fts5yytestcase() macro to be a no-op if is not already defined

//
// Applications can choose to define fts5yytestcase() in the %include section

// code the fts5yytestcase() macro should be turned off.  But it is useful
// for testing.

// Next are the tables used to determine what action to take based on the
// current state and lookahead token.  These tables are used to implement
// functions that take a state number and lookahead value and return an
// action integer.
//
// Suppose the action integer is N.  Then the action is determined as
// follows
//
//   0 <= N <= fts5YY_MAX_SHIFT             Shift N.  That is, push the lookahead
//                                      token onto the stack and goto state N.
//
//   N between fts5YY_MIN_SHIFTREDUCE       Shift to an arbitrary state then
//     and fts5YY_MAX_SHIFTREDUCE           reduce by rule N-fts5YY_MIN_SHIFTREDUCE.
//
//   N == fts5YY_ERROR_ACTION               A syntax error has occurred.
//
//   N == fts5YY_ACCEPT_ACTION              The parser accepts its input.
//
//   N == fts5YY_NO_ACTION                  No such action.  Denotes unused
//                                      slots in the fts5yy_action[] table.
//
//   N between fts5YY_MIN_REDUCE            Reduce by rule N-fts5YY_MIN_REDUCE
//     and fts5YY_MAX_REDUCE
//
// The action table is constructed as a single large table named fts5yy_action[].
// Given state S and lookahead X, the action is computed as either:
//
//    (A)   N = fts5yy_action[ fts5yy_shift_ofst[S] + X ]
//    (B)   N = fts5yy_default[S]
//
// The (A) formula is preferred.  The B formula is used instead if
// fts5yy_lookahead[fts5yy_shift_ofst[S]+X] is not equal to X.
//
// The formulas above are for computing the action when the lookahead is
// a terminal symbol.  If the lookahead is a non-terminal (as occurs after
// a reduce action) then the fts5yy_reduce_ofst[] array is used in place of
// the fts5yy_shift_ofst[] array.
//
// The following are the tables generated in this section:
//
//  fts5yy_action[]        A single table containing all actions.
//  fts5yy_lookahead[]     A table containing the lookahead for each entry in
//                     fts5yy_action.  Used to detect hash collisions.
//  fts5yy_shift_ofst[]    For each state, the offset into fts5yy_action for
//                     shifting terminals.
//  fts5yy_reduce_ofst[]   For each state, the offset into fts5yy_action for
//                     shifting non-terminals after a reduce.
//  fts5yy_default[]       Default action for each state.

// Low level access to the FTS index stored in the database file. The
// routines in this file file implement all read and write access to the
// %_data table. Other parts of the system access this functionality via
// the interface defined in fts5Int.h.

// #include "fts5Int.h"

// Overview:
//
// The %_data table contains all the FTS indexes for an FTS5 virtual table.
// As well as the main term index, there may be up to 31 prefix indexes.
// The format is similar to FTS3/4, except that:
//
//   * all segment b-tree leaf data is stored in fixed size page records
//     (e.g. 1000 bytes). A single doclist may span multiple pages. Care is
//     taken to ensure it is possible to iterate in either direction through
//     the entries in a doclist, or to seek to a specific entry within a
//     doclist, without loading it into memory.
//
//   * large doclists that span many pages have associated "doclist index"
//     records that contain a copy of the first rowid on each page spanned by
//     the doclist. This is used to speed up seek operations, and merges of
//     large doclists with very small doclists.
//
//   * extra fields in the "structure record" record the state of ongoing
//     incremental merge operations.
//

// Details:
//
// The %_data table managed by this module,
//
//     CREATE TABLE %_data(id INTEGER PRIMARY KEY, block BLOB);
//
// , contains the following 5 types of records. See the comments surrounding
// the FTS5_*_ROWID macros below for a description of how %_data rowids are
// assigned to each fo them.
//
// 1. Structure Records:
//
//   The set of segments that make up an index - the index structure - are
//   recorded in a single record within the %_data table. The record consists
//   of a single 32-bit configuration cookie value followed by a list of
//   SQLite varints. If the FTS table features more than one index (because
//   there are one or more prefix indexes), it is guaranteed that all share
//   the same cookie value.
//
//   Immediately following the configuration cookie, the record begins with
//   three varints:
//
//     + number of levels,
//     + total number of segments on all levels,
//     + value of write counter.
//
//   Then, for each level from 0 to nMax:
//
//     + number of input segments in ongoing merge.
//     + total number of segments in level.
//     + for each segment from oldest to newest:
//         + segment id (always > 0)
//         + first leaf page number (often 1, always greater than 0)
//         + final leaf page number
//
// 2. The Averages Record:
//
//   A single record within the %_data table. The data is a list of varints.
//   The first value is the number of rows in the index. Then, for each column
//   from left to right, the total number of tokens in the column for all
//   rows of the table.
//
// 3. Segment leaves:
//
//   TERM/DOCLIST FORMAT:
//
//     Most of each segment leaf is taken up by term/doclist data. The
//     general format of term/doclist, starting with the first term
//     on the leaf page, is:
//
//         varint : size of first term
//         blob:    first term data
//         doclist: first doclist
//         zero-or-more {
//           varint:  number of bytes in common with previous term
//           varint:  number of bytes of new term data (nNew)
//           blob:    nNew bytes of new term data
//           doclist: next doclist
//         }
//
//     doclist format:
//
//         varint:  first rowid
//         poslist: first poslist
//         zero-or-more {
//           varint:  rowid delta (always > 0)
//           poslist: next poslist
//         }
//
//     poslist format:
//
//         varint: size of poslist in bytes multiplied by 2, not including
//                 this field. Plus 1 if this entry carries the "delete" flag.
//         collist: collist for column 0
//         zero-or-more {
//           0x01 byte
//           varint: column number (I)
//           collist: collist for column I
//         }
//
//     collist format:
//
//         varint: first offset + 2
//         zero-or-more {
//           varint: offset delta + 2
//         }
//
//   PAGE FORMAT
//
//     Each leaf page begins with a 4-byte header containing 2 16-bit
//     unsigned integer fields in big-endian format. They are:
//
//       * The byte offset of the first rowid on the page, if it exists
//         and occurs before the first term (otherwise 0).
//
//       * The byte offset of the start of the page footer. If the page
//         footer is 0 bytes in size, then this field is the same as the
//         size of the leaf page in bytes.
//
//     The page footer consists of a single varint for each term located
//     on the page. Each varint is the byte offset of the current term
//     within the page, delta-compressed against the previous value. In
//     other words, the first varint in the footer is the byte offset of
//     the first term, the second is the byte offset of the second less that
//     of the first, and so on.
//
//     The term/doclist format described above is accurate if the entire
//     term/doclist data fits on a single leaf page. If this is not the case,
//     the format is changed in two ways:
//
//       + if the first rowid on a page occurs before the first term, it
//         is stored as a literal value:
//
//             varint:  first rowid
//
//       + the first term on each page is stored in the same way as the
//         very first term of the segment:
//
//             varint : size of first term
//             blob:    first term data
//
// 5. Segment doclist indexes:
//
//   Doclist indexes are themselves b-trees, however they usually consist of
//   a single leaf record only. The format of each doclist index leaf page
//   is:
//
//     * Flags byte. Bits are:
//         0x01: Clear if leaf is also the root page, otherwise set.
//
//     * Page number of fts index leaf page. As a varint.
//
//     * First rowid on page indicated by previous field. As a varint.
//
//     * A list of varints, one for each subsequent termless page. A
//       positive delta if the termless page contains at least one rowid,
//       or an 0x00 byte otherwise.
//
//   Internal doclist index nodes are:
//
//     * Flags byte. Bits are:
//         0x01: Clear for root page, otherwise set.
//
//     * Page number of first child page. As a varint.
//
//     * Copy of first rowid on page indicated by previous field. As a varint.
//
//     * A list of delta-encoded varints - the first rowid on each subsequent
//       child page.
//

// Rowids for the averages and structure records in the %_data table.

// Macros determining the rowids used by segment leaves and dlidx leaves
// and nodes. All nodes and leaves are stored in the %_data table with large
// positive rowids.
//
// Each segment has a unique non-zero 16-bit id.
//
// The rowid for each segment leaf is found by passing the segment id and
// the leaf page number to the FTS5_SEGMENT_ROWID macro. Leaves are numbered
// sequentially starting from 1.

// Each time a blob is read from the %_data table, it is padded with this
// many zero bytes. This makes it easier to decode the various record formats
// without overreading if the records are corrupt.

// NOTES ON TRANSACTIONS:
//
// SQLite invokes the following virtual table methods as transactions are
// opened and closed by the user:
//
//     xBegin():    Start of a new transaction.
//     xSync():     Initial part of two-phase commit.
//     xCommit():   Final part of two-phase commit.
//     xRollback(): Rollback the transaction.
//
// Anything that is required as part of a commit that may fail is performed
// in the xSync() callback. Current versions of SQLite ignore any errors
// returned by xCommit().
//
// And as sub-transactions are opened/closed:
//
//     xSavepoint(int S):  Open savepoint S.
//     xRelease(int S):    Commit and close savepoint S.
//     xRollbackTo(int S): Rollback to start of savepoint S.
//
// During a write-transaction the fts5_index.c module may cache some data
// in-memory. It is flushed to disk whenever xSync(), xRelease() or
// xSavepoint() is called. And discarded whenever xRollback() or xRollbackTo()
// is called.
//
// Additionally, if SQLITE_DEBUG is defined, an instance of the following
// structure is used to record the current transaction state. This information
// is not required, but it is used in the assert() statements executed by
// function fts5CheckTransactionState() (see below).

//
//   5. ORDER BY rank [ASC|DESC]
//   6. ORDER BY rowid [ASC|DESC]
//
// Information for the xFilter call is passed via both the idxNum and

//
//     FTS5_BI_ORDER_RANK
//     FTS5_BI_ORDER_ROWID
//     FTS5_BI_ORDER_DESC
//

//   Match against rank column:             "r"
//   Match against other column:            "M<column-number>"
//   LIKE  against other column:            "L<column-number>"
//   GLOB  against other column:            "G<column-number>"
//   Equality constraint against the rowid: "="
//   A < or <= against the rowid:           "<"
//   A > or >= against the rowid:           ">"
//
// This function ensures that there is at most one "r" or "=". And that if
// there exists an "=" then there is no "<" or ">".
//
// Costs are assigned as follows:
//
//  a) If an unusable MATCH operator is present in the WHERE clause, the
//     cost is unconditionally set to 1e50 (a really big number).
//
//  a) If a MATCH operator is present, the cost depends on the other
//     constraints also present. As follows:
//
//       * No other constraints:         cost=1000.0
//       * One rowid range constraint:   cost=750.0
//       * Both rowid range constraints: cost=500.0
//       * An == rowid constraint:       cost=100.0
//
//  b) Otherwise, if there is no MATCH:
//
//       * No other constraints:         cost=1000000.0
//       * One rowid range constraint:   cost=750000.0
//       * Both rowid range constraints: cost=250000.0
//       * An == rowid constraint:       cost=10.0
