//
// 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() upgrades the database file lock. In other words, xLock() moves the
// database file lock in the direction NONE toward EXCLUSIVE. The argument to
// xLock() is always on of SHARED, RESERVED, PENDING, or EXCLUSIVE, never
// SQLITE_LOCK_NONE. If the database file lock is already at or above the
// requested lock, then the call to xLock() is a no-op.
// xUnlock() downgrades the database file lock to either SHARED or NONE.
//
// If the lock is already at or below the requested lock state, then the call
//
// to xUnlock() is a no-op.
// 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.

// 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_IOERR. Or the implementation might recognize that a database
// file will be doing page-aligned sector reads and writes in a random
// order and set up its I/O subsystem accordingly.
//
// SQLite might also add one of the following flags to the xOpen method:
//
// <ul>
// <li> [SQLITE_OPEN_DELETEONCLOSE]
// <li> [SQLITE_OPEN_EXCLUSIVE]
// </ul>
//
// The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
// deleted when it is closed. ^The [SQLITE_OPEN_DELETEONCLOSE]
// will be set for TEMP databases and their journals, transient
// databases, and subjournals.
//
// ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
// with the [SQLITE_OPEN_CREATE] flag, which are both directly
// analogous to the O_EXCL and O_CREAT flags of the POSIX open()
// API. The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
// SQLITE_OPEN_CREATE, is used to indicate that file should always
// be created, and that it is an error if it already exists.
// It is <i>not</i> used to indicate the file should be opened
// for exclusive access.
//
// ^At least szOsFile bytes of memory are allocated by SQLite
// to hold the [sqlite3_file] structure passed as the third
// argument to xOpen. The xOpen method does not have to
// allocate the structure; it should just fill it in. Note that
// the xOpen method must set the sqlite3_file.pMethods to either
// a valid [sqlite3_io_methods] object or to NULL. xOpen must do
// this even if the open fails. SQLite expects that the sqlite3_file.pMethods
// element will be valid after xOpen returns regardless of the success
// or failure of the xOpen call.
//
// [[sqlite3_vfs.xAccess]]
// ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
// to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
// test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
// to test whether a file is at least readable. The SQLITE_ACCESS_READ
// flag is never actually used and is not implemented in the built-in
// VFSes of SQLite. The file is named by the second argument and can be a
// directory. The xAccess method returns [SQLITE_OK] on success or some
// non-zero error code if there is an I/O error or if the name of
// the file given in the second argument is illegal. If SQLITE_OK
// is returned, then non-zero or zero is written into *pResOut to indicate
// whether or not the file is accessible.
//
// ^SQLite will always allocate at least mxPathname+1 bytes for the
// output buffer xFullPathname. The exact size of the output buffer
// is also passed as a parameter to both methods. If the output buffer
// is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
// handled as a fatal error by SQLite, vfs implementations should endeavor
// to prevent this by setting mxPathname to a sufficiently large value.
//
// The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
// interfaces are not strictly a part of the filesystem, but they are
// included in the VFS structure for completeness.
// The xRandomness() function attempts to return nBytes bytes
// of good-quality randomness into zOut. The return value is
// the actual number of bytes of randomness obtained.
// The xSleep() method causes the calling thread to sleep for at
// least the number of microseconds given. ^The xCurrentTime()
// method returns a Julian Day Number for the current date and time as
// a floating point value.
// ^The xCurrentTimeInt64() method returns, as an integer, the Julian
// Day Number multiplied by 86400000 (the number of milliseconds in
// a 24-hour day).
// ^SQLite will use the xCurrentTimeInt64() method to get the current
// date and time if that method is available (if iVersion is 2 or
// greater and the function pointer is not NULL) and will fall back
// to xCurrentTime() if xCurrentTimeInt64() is unavailable.
//
// ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
// are not used by the SQLite core. These optional interfaces are provided
// by some VFSes to facilitate testing of the VFS code. By overriding
// system calls with functions under its control, a test program can
// simulate faults and error conditions that would otherwise be difficult
// or impossible to induce. The set of system calls that can be overridden
// varies from one VFS to another, and from one version of the same VFS to the
// next. Applications that use these interfaces must be prepared for any
// or all of these interfaces to be NULL or for their behavior to change
// from one release to the next. Applications must not attempt to access
// any of these methods if the iVersion of the VFS is less than 3.

//
// An instance of this object defines the interface between SQLite
// and low-level memory allocation routines.
//
// This object is used in only one place in the SQLite interface.
// A pointer to an instance of this object is the argument to
// [sqlite3_config()] when the configuration option is
// [SQLITE_CONFIG_MALLOC] or [SQLITE_CONFIG_GETMALLOC].
// By creating an instance of this object
// and passing it to [sqlite3_config]([SQLITE_CONFIG_MALLOC])
// during configuration, an application can specify an alternative
// memory allocation subsystem for SQLite to use for all of its
// dynamic memory needs.
//
// Note that SQLite comes with several [built-in memory allocators]
// that are perfectly adequate for the overwhelming majority of applications
// and that this object is only useful to a tiny minority of applications
// with specialized memory allocation requirements. This object is
// also used during testing of SQLite in order to specify an alternative
// memory allocator that simulates memory out-of-memory conditions in
// order to verify that SQLite recovers gracefully from such
// conditions.
//
// The xMalloc, xRealloc, and xFree methods must work like the
// malloc(), realloc() and free() functions from the standard C library.
// ^SQLite guarantees that the second argument to
// xRealloc is always a value returned by a prior call to xRoundup.
//
// xSize should return the allocated size of a memory allocation
// previously obtained from xMalloc or xRealloc. The allocated size
// is always at least as big as the requested size but may be larger.
//
// The xRoundup method returns what would be the allocated size of
// a memory allocation given a particular requested size. Most memory
// allocators round up memory allocations at least to the next multiple
// of 8. Some allocators round up to a larger multiple or to a power of 2.
// Every memory allocation request coming in through [sqlite3_malloc()]
// or [sqlite3_realloc()] first calls xRoundup. If xRoundup returns 0,
// that causes the corresponding memory allocation to fail.
//
// The xInit method initializes the memory allocator. For example,
// it might allocate any required mutexes or initialize internal data
// structures. The xShutdown method is invoked (indirectly) by
// [sqlite3_shutdown()] and should deallocate any resources acquired
// by xInit. The pAppData pointer is used as the only parameter to
// xInit and xShutdown.
//
// SQLite holds the [SQLITE_MUTEX_STATIC_MAIN] mutex when it invokes
// the xInit method, so the xInit method need not be threadsafe. The
// xShutdown method is only called from [sqlite3_shutdown()] so it does
// not need to be threadsafe either. For all other methods, SQLite
// holds the [SQLITE_MUTEX_STATIC_MEM] mutex as long as the
// [SQLITE_CONFIG_MEMSTATUS] configuration option is turned on (which
// it is by default) and so the methods are automatically serialized.
// However, if [SQLITE_CONFIG_MEMSTATUS] is disabled, then the other
// methods must be threadsafe or else make their own arrangements for
// serialization.
//
// SQLite will never invoke xInit() more than once without an intervening
// call to xShutdown().

//
// ^The xMutexInit method defined by this structure is invoked as

// in multithreaded applications.
//
// ^SQLite will never invoke xInit() more than once without an intervening
// call to xShutdown().
//
// [[the xCreate() page cache methods]]
// ^SQLite invokes the xCreate() method to construct a new cache instance.
// SQLite will typically create one cache instance for each open database file,

// first parameter, szPage, is the size in bytes of the pages that must

// a number less than 250. SQLite will use the

// database page on disk. The value passed into szExtra depends
// on the SQLite version, the target platform, and how SQLite was compiled.
// ^The third argument to xCreate(), bPurgeable, is true if the cache being
// created will be used to cache database pages of a file stored on disk, or
// 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;
// it is purely advisory. ^On a cache where bPurgeable is false, SQLite will

// ^In other words, calls to xUnpin() on a cache with bPurgeable set to

// ^Hence, a cache created with bPurgeable false will
// never contain any unpinned pages.
//
// [[the xCachesize() page cache method]]
// ^(The xCachesize() method may be called at any time by SQLite to set the

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

// The xFetch() method locates a page in the cache and returns a pointer to

// The pBuf element of the returned sqlite3_pcache_page object will be a
// pointer to a buffer of szPage bytes used to store the content of a
// 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
// implementation must return a pointer to the page buffer with its content

// <tr><td> 2 <td> Make every effort to allocate a new page. Only return
//
// NULL if allocating a new page is effectively impossible.

//
// ^(SQLite will normally invoke xFetch() with a createFlag of 0 or 1. SQLite
// will only use a createFlag of 2 after a prior call with a createFlag of 1

//
// [[the xUnpin() page cache method]]
// ^xUnpin() is called by SQLite with a pointer to a currently pinned page
// as its second argument. If the third parameter, discard, is non-zero,
// then the page must be evicted from the cache.
// ^If the discard parameter is

// may choose to evict unpinned pages at any time.
//
// The cache must not perform any reference counting. A single
// call to xUnpin() unpins the page regardless of the number of prior calls

//
// [[the xRekey() page cache methods]]
// The xRekey() method is used to change the key value associated with the

//
// When SQLite calls the xTruncate() method, the cache must discard all

// 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().
// <li> The sqlite3_rebaser object is deleted by calling
// sqlite3rebaser_delete().
//

//
// (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.

// Notes On Invalid UTF-8:
//
// - This routine never allows a 7-bit character (0x00 through 0x7f) to
// be encoded as a multi-byte character. Any multi-byte character that
// attempts to encode a value between 0x00 and 0x7f is rendered as 0xfffd.
//
// - This routine never allows a UTF16 surrogate value to be encoded.
// 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.

// 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.

// Allocate and initialize a new Pager object and put a pointer to it
// in *ppPager. The pager should eventually be freed by passing it
// to sqlite3PagerClose().
//
// The zFilename argument is the path to the database file to open.
// If zFilename is NULL then a randomly-named temporary file is created
// and used as the file to be cached. Temporary files are be deleted
// automatically when they are closed. If zFilename is ":memory:" then
// all information is held in cache. It is never written to disk.
// This can be used to implement an in-memory database.
//
// The nExtra parameter specifies the number of bytes of space allocated
// along with each page reference. This space is available to the user
// via the sqlite3PagerGetExtra() API. When a new page is allocated, the
// first 8 bytes of this space are zeroed but the remainder is uninitialized.
// (The extra space is used by btree as the MemPage object.)
//
// The flags argument is used to specify properties that affect the
// operation of the pager. It should be passed some bitwise combination
// of the PAGER_* flags.
//
// The vfsFlags parameter is a bitmask to pass to the flags parameter
// of the xOpen() method of the supplied VFS when opening files.
//
// If the pager object is allocated and the specified file opened
// successfully, SQLITE_OK is returned and *ppPager set to point to
// the new pager object. If an error occurs, *ppPager is set to NULL
// and error code returned. This function may return SQLITE_NOMEM
// (sqlite3Malloc() is used to allocate memory), SQLITE_CANTOPEN or
// various SQLITE_IO_XXX errors.

// (see SQLITE_CONFIG_WORKER_THREADS) plus one (the main thread). Thus for
// single-threaded operation, there is exactly one instance of this object
// and for multi-threaded operation there are two or more instances.
//
// Essentially, this structure contains all those fields of the VdbeSorter
// structure for which each thread requires a separate instance. For example,
// each thread requries its own UnpackedRecord object to unpack records in
// as part of comparison operations.
//
// Before a background thread is launched, variable bDone is set to 0. Then,
// right before it exits, the thread itself sets bDone to 1. This is used for
// two purposes:
//
// 1. When flushing the contents of memory to a level-0 PMA on disk, to
// attempt to select a SortSubtask for which there is not already an
// active background thread (since doing so causes the main thread
// to block until it finishes).
//
// 2. If SQLITE_DEBUG_SORTER_THREADS is defined, to determine if a call
// to sqlite3ThreadJoin() is likely to block. Cases that are likely to
// block provoke debugging output.
//
// In both cases, the effects of the main thread seeing (bDone==0) even
// after the thread has finished are not dire. So we don't worry about
// memory barriers and such here.

// This routine walks an expression tree and resolves references to
// table columns and result-set columns. At the same time, do error
// checking on function usage and set a flag if any aggregate functions
// 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}.

// Generate code that will increment the schema cookie.
//
// The schema cookie is used to determine when the schema for the
// database changes. After each schema change, the cookie value
// changes. When a process first reads the schema it records the
// cookie. Thereafter, whenever it goes to access the database,
// it checks the cookie to make sure the schema has not changed
// since it was last read.
//
// This plan is not completely bullet-proof. It is possible for
// the schema to change multiple times and for the cookie to be
// set back to prior value. But schema changes are infrequent
// and the probability of hitting the same cookie value is only
// 1 chance in 2^32. So we're safe enough.

// IMPLEMENTATION-OF: R-34230-56049 SQLite automatically increments
// the schema-version whenever the schema changes.

// If iIdxNoSeek is a valid cursor number (>=0) not equal to iDataCur,

// A foreign key constraint requires that the key columns in the parent

//
// 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

//
// 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

//
// The IDLIST following the table name is always optional. If omitted,
// then a list of all (non-hidden) columns for the table is substituted.
// The IDLIST appears in the pColumn parameter. pColumn is NULL if IDLIST
// is omitted.
//
// For the pSelect parameter holds the values to be inserted for the
// first two forms shown above. A VALUES clause is really just short-hand
// 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>

// Generate code to do constraint checks prior to an INSERT or an UPDATE
// on table pTab.
//
// The regNewData parameter is the first register in a range that contains
// the data to be inserted or the data after the update. There will be
// pTab->nCol+1 registers in this range. The first register (the one
// that regNewData points to) will contain the new rowid, or NULL in the
// case of a WITHOUT ROWID table. The second register in the range will
// contain the content of the first table column. The third register will
// contain the content of the second table column. And so forth.
//
// The regOldData parameter is similar to regNewData except that it contains
// the data prior to an UPDATE rather than afterwards. regOldData is zero
// 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
// rowid for a normal table or the PRIMARY KEY for a WITHOUT ROWID table)
// 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
// record be generated during constraint checks to avoid affinity changes
// to the register content that occur after constraint checks but before
// the new record is inserted.
//
// 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
// for the first index in the pTab->pIndex list. Cursors for other indices
// are at iIdxCur+N for the N-th element of the pTab->pIndex list.
//
// This routine also generates code to check constraints. NOT NULL,
// CHECK, and UNIQUE constraints are all checked. If a constraint fails,
// then the appropriate action is performed. There are five possible
// actions: ROLLBACK, ABORT, FAIL, REPLACE, and IGNORE.
//
// 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.

// Add a new cleanup operation to a Parser. The cleanup should happen when
// the parser object is destroyed. But, beware: the cleanup might happen

//
// Use this mechanism for uncommon cleanups. There is a higher setup
// cost for this mechansim (an extra malloc), so it should not be used
// for common cleanups that happen on most calls. But for less
// common cleanups, we save a single NULL-pointer comparison in
// sqlite3ParseObjectReset(), which reduces the total CPU cycle count.
//
// If a memory allocation error occurs, then the cleanup happens immediately.
// When either SQLITE_DEBUG or SQLITE_COVERAGE_TEST are defined, the
// pParse->earlyCleanup flag is set in that case. Calling code show verify
// that test cases exist for which this happens, to guard against possible
// use-after-free errors following an OOM. The preferred way to do this is
// to immediately follow the call to this routine with:
//
// testcase( pParse->earlyCleanup );
//
// This routine returns a copy of its pPtr input (the third parameter)
// except if an early cleanup occurs, in which case it returns NULL. So
// another way to check for early cleanup is to check the return value.
// Or, stop using the pPtr parameter with this call and use only its
// return value thereafter. Something like this:

//
// INNER CROSS JOIN -> same as JOIN
// NATURAL CROSS JOIN -> same as NATURAL JOIN
// OUTER LEFT JOIN -> same as LEFT JOIN
// LEFT NATURAL JOIN -> same as NATURAL LEFT JOIN
// LEFT RIGHT JOIN -> same as FULL JOIN
// RIGHT OUTER FULL JOIN -> same as FULL JOIN
// CROSS CROSS CROSS JOIN -> same as JOIN
//
// The only restrictions on the join type name are:
//
// - "INNER" cannot appear together with "OUTER", "LEFT", "RIGHT",
// or "FULL".
//
// - "CROSS" cannot appear together with "OUTER", "LEFT", "RIGHT,

// This is called to code the required FOR EACH ROW triggers for an operation

// is given by the op parameter. The tr_tm parameter determines whether the
// BEFORE or AFTER triggers are coded. If the operation is an UPDATE, then
// parameter pChanges is passed the list of columns being modified.
//
// If there are no triggers that fire at the specified time for the specified
// operation on pTab, this function is a no-op.
//
// The reg argument is the address of the first in an array of registers
// that contain the values substituted for the new.* and old.* references
// in the trigger program. If N is the number of columns in table pTab
// (a copy of pTab->nCol), then registers are populated as follows:
//
// Register Contains
// ------------------------------------------------------
// reg+0 OLD.rowid
// reg+1 OLD.* value of left-most column of pTab
// ... ...
// reg+N OLD.* value of right-most column of pTab
// reg+N+1 NEW.rowid
// reg+N+2 NEW.* value of left-most column of pTab
// ... ...
// reg+N+N+1 NEW.* value of right-most column of pTab
//
// For ON DELETE triggers, the registers containing the NEW.* values will
// never be accessed by the trigger program, so they are not allocated or
// populated by the caller (there is no data to populate them with anyway).
// Similarly, for ON INSERT triggers the values stored in the OLD.* registers
// are never accessed, and so are not allocated by the caller. So, for an
// ON INSERT trigger, the value passed to this function as parameter reg
// is not a readable register, although registers (reg+N) through
// (reg+N+N+1) are.
//
// Parameter orconf is the default conflict resolution algorithm for the
// trigger program to use (REPLACE, IGNORE etc.). Parameter ignoreJump
// is the instruction that control should jump to if a trigger program
// raises an IGNORE exception.

// The most recently coded instruction was an OP_Column to retrieve the
// i-th column of table pTab. This routine sets the P4 parameter of the
// OP_Column to the default value, if any.
//
// The default value of a column is specified by a DEFAULT clause in the
// column definition. This was either supplied by the user when the table
// was created, or added later to the table definition by an ALTER TABLE
// command. If the latter, then the row-records in the table btree on disk
// may not contain a value for the column and the default value, taken
// from the P4 parameter of the OP_Column instruction, is returned instead.
// If the former, then all row-records are guaranteed to include a value
// for the column and the P4 value is not required.
//
// Column definitions created by an ALTER TABLE command may only have
// literal default values specified: a number, null or a string. (If a more
// complicated default expression value was provided, it is evaluated
// when the ALTER TABLE is executed and one of the literal values written
// into the sqlite_schema table.)
//
// Therefore, the P4 parameter is only required if the default value for
// the column is a literal number, string or null. The sqlite3ValueFromExpr()
// function is capable of transforming these types of expressions into
// sqlite3_value objects.
//
// If column as REAL affinity and the table is an ordinary b-tree table
// (not a virtual table) then the value might have been stored as an
// integer. In that case, add an OP_RealAffinity opcode to make sure
// it has been converted into REAL.

// 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.

// this function may be called on the returned WhereInfo object. It returns
// true if the rows really will be sorted in the specified order, or false
// otherwise.

// For example, assuming:
//
// CREATE INDEX i1 ON t1(x, Y);
//
// then
//

// 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.

// sqlite3WhereBegin() has already been called for the SELECT statement
// passed as the second argument when this function is invoked. It generates
// code to populate the Window.regResult register for each window function
// and invoke the sub-routine at instruction addrGosub once for each row.
// sqlite3WhereEnd() is always called before returning.
//
// This function handles several different types of window frames, which
// require slightly different processing. The following pseudo code is
// used to implement window frames of the form:
//
// ROWS BETWEEN <expr1> PRECEDING AND <expr2> FOLLOWING
//
// Other window frame types use variants of the following:
//
// ... loop started by sqlite3WhereBegin() ...
// if( new partition ){
// Gosub flush
// }
// Insert new row into eph table.
//
// if( first row of partition ){
// // Rewind three cursors, all open on the eph table.
// Rewind(csrEnd);
// Rewind(csrStart);
// Rewind(csrCurrent);
//
// regEnd = <expr2> // FOLLOWING expression
// regStart = <expr1> // PRECEDING expression
// }else{
// // First time this branch is taken, the eph table contains two
// // rows. The first row in the partition, which all three cursors
// // currently point to, and the following row.
// AGGSTEP
// if( (regEnd--)<=0 ){
// RETURN_ROW
// if( (regStart--)<=0 ){
// AGGINVERSE
// }
// }
// }
// }
// flush:
// AGGSTEP
// while( 1 ){
// RETURN ROW
// if( csrCurrent is EOF ) break;
// if( (regStart--)<=0 ){
// AggInverse(csrStart)
// Next(csrStart)
// }
// }
//
// 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
//
// ... 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( (regEnd--)<=0 ){
// AGGSTEP
// }
// RETURN_ROW
// if( (regStart--)<=0 ){
// AGGINVERSE
// }
// }
// }
// flush:
// if( (regEnd--)<=0 ){
// AGGSTEP
// }
// RETURN_ROW
//
//
// ROWS BETWEEN <expr1> FOLLOWING 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 = regEnd - <expr1>
// }else{
// AGGSTEP
// if( (regEnd--)<=0 ){
// RETURN_ROW
// }
// if( (regStart--)<=0 ){
// AGGINVERSE
// }
// }
// }
// flush:
// AGGSTEP
// while( 1 ){
// if( (regEnd--)<=0 ){
// RETURN_ROW
// if( eof ) break;
// }
// if( (regStart--)<=0 ){
// AGGINVERSE
// if( eof ) break
// }
// }
// while( !eof csrCurrent ){
// RETURN_ROW
// }
//
// 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
// }
// Insert new row into eph table.
// if( first row of partition ){
// Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
// regStart = <expr1>
// }else{
// AGGSTEP
// }
// }
// flush:
// AGGSTEP
// while( 1 ){
// if( (regStart--)<=0 ){
// AGGINVERSE
// if( eof ) break
// }
// RETURN_ROW
// }
// while( !eof csrCurrent ){
// RETURN_ROW
// }
//
// 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 ){
// AGGINVERSE
// }
// }
// }
// }
// flush:
// AGGSTEP
// while( 1 ){
// RETURN ROW
// if( csrCurrent is EOF ) break;
// while( csrStart.key + regStart) < csrCurrent.key ){
// AGGINVERSE
// }
// }
// }
//
// In the above notation, "csr.key" means the current value of the ORDER BY

// The next sections is a series of control #defines.

//
// 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
// YY_ERROR_ACTION The yy_action[] code for syntax error
// YY_ACCEPT_ACTION The yy_action[] code for accept
// YY_NO_ACTION The yy_action[] code for no-op
// YY_MIN_REDUCE Minimum value for reduce actions
// YY_MAX_REDUCE Maximum value for reduce actions

// The first argument to this function is the name of the VFS to use (or
// a NULL to signify the default VFS) if the URI does not contain a "vfs=xxx"
// query parameter. The second argument contains the URI (or non-URI filename)
// itself. When this function is called the *pFlags variable should contain
// the default flags to open the database handle with. The value stored in
// *pFlags may be updated before returning if the URI filename contains
// "cache=xxx" or "mode=xxx" query parameters.
//
// If successful, SQLITE_OK is returned. In this case *ppVfs is set to point to
// the VFS that should be used to open the database file. *pzFile is set to
// point to a buffer containing the name of the file to open. The value
// stored in *pzFile is a database name acceptable to sqlite3_uri_parameter()
// and is in the same format as names created using sqlite3_create_filename().
// The caller must invoke sqlite3_free_filename() (not sqlite3_free()!) on
// the value returned in *pzFile to avoid a memory leak.
//
// If an error occurs, then an SQLite error code is returned and *pzErrMsg
// may be set to point to a buffer containing an English language error
// message. It is the responsibility of the caller to eventually release

//
// 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()
// sqlite3Fts5ParserARG_SDECL A static variable declaration for the %extra_argument
// sqlite3Fts5ParserARG_PDECL A parameter declaration for the %extra_argument
// sqlite3Fts5ParserARG_PARAM Code to pass %extra_argument as a subroutine parameter
// sqlite3Fts5ParserARG_STORE Code to store %extra_argument into fts5yypParser
// sqlite3Fts5ParserARG_FETCH Code to extract %extra_argument from fts5yypParser
// sqlite3Fts5ParserCTX_* As sqlite3Fts5ParserARG_ except for %extra_context
// fts5YYERRORSYMBOL is the code number of the error symbol. If not
// defined, then do no error processing.
// fts5YYNSTATE the combined number of states.
// fts5YYNRULE the number of rules in the grammar
// fts5YYNFTS5TOKEN Number of terminal symbols
// fts5YY_MAX_SHIFT Maximum value for shift actions
// fts5YY_MIN_SHIFTREDUCE Minimum value for shift-reduce actions
// fts5YY_MAX_SHIFTREDUCE Maximum value for shift-reduce actions
// fts5YY_ERROR_ACTION The fts5yy_action[] code for syntax error
// fts5YY_ACCEPT_ACTION The fts5yy_action[] code for accept
// fts5YY_NO_ACTION The fts5yy_action[] code for no-op
// fts5YY_MIN_REDUCE Minimum value for reduce actions
// fts5YY_MAX_REDUCE Maximum value for reduce actions

// 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).

// Each entry in the following array defines a rule for folding a range

// codepoints starting at codepoint iCode.
//
// If the least significant bit in flags is clear, then the rule applies
// to all nRange codepoints (i.e. all nRange codepoints are upper case and
// need to be folded). Or, if it is set, then the rule only applies to
// every second codepoint in the range, starting with codepoint C.
//
// The 7 most significant bits in flags are an index into the aiOff[]
// array. If a specific codepoint C does require folding, then its lower
// case equivalent is ((C + aiOff[flags>>1]) & 0xFFFF).
