Upgrade our sqlite to 3.6.1, with the local changes made by Gears. I'm
checking in the full sqlite tree to make upstream merges easier. This means we'll have generated sources split out from the originals. One important change this makes is that "BEGIN" now defaults to "BEGIN IMMEDIATE" rather than "BEGIN DEFERRED". This doesn't affect us because we don't use unqualified BEGIN statements. The full CL is too big for Rietveld. I'm splitting it into 2. This one is reviewable. The other CL is just a fresh drop of: //depot/googleclient/gears/opensource/third_party/sqlite_google Review URL: http://codereview.chromium.org/15067 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@7623 0039d316-1c4b-4281-b951-d872f2087c98

+** Suppose the action integer is N. Then the action is determined as

+**
+** 0 <= N < YYNSTATE Shift N. That is, push the lookahead
+** token onto the stack and goto state N.

+** The action table is constructed as a single large table named yy_action[].
+** Given state S and lookahead X, the action is computed as
+**
+** yy_action[ yy_shift_ofst[S] + X ]
+**
+** If the index value yy_shift_ofst[S]+X is out of range or if the value

+** and that yy_default[S] should be used instead.
+**
+** The formula above is 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 and YY_REDUCE_USE_DFLT is used in place of
+** YY_SHIFT_USE_DFLT.

+** 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

+** CAPI3REF: OS Interface Object {H11140} <S20100>
+**
+** 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".
+**
+** The value of the iVersion field is initially 1 but may be larger in
+** future versions of SQLite. Additional fields may be appended to this
+** object when the iVersion value is increased. Note that the structure
+** of the sqlite3_vfs object changes in the transaction between
+** SQLite version 3.5.9 and 3.6.0 and yet the iVersion field was not
+** modified.
+**
+** 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.
+**
+** {H11141} SQLite will guarantee that the zFilename parameter to xOpen
+** is either a NULL pointer or string obtained
+** from xFullPathname(). SQLite further guarantees that
+** the string will be valid and unchanged until xClose() is
+** called. {END} Because of the previous sentense,
+** 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 is xOpen is a NULL pointer then xOpen
+** must invite 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].
+**
+** {H11142} 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]. {END}
+** If xOpen() opens a file read-only then it sets *pOutFlags to
+** include [SQLITE_OPEN_READONLY]. Other bits in *pOutFlags may be set.
+**
+** {H11143} 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_MASTER_JOURNAL]
+** </ul> {END}
+**
+** 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>
+**
+** {H11145} The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
+** deleted when it is closed. {H11146} The [SQLITE_OPEN_DELETEONCLOSE]
+** will be set for TEMP databases, journals and for subjournals.
+**
+** {H11147} The [SQLITE_OPEN_EXCLUSIVE] flag means the file should be opened
+** for exclusive access. This flag is set for all files except
+** for the main database file.
+**
+** {H11148} At least szOsFile bytes of memory are allocated by SQLite
+** to hold the [sqlite3_file] structure passed as the third
+** argument to xOpen. {END} The xOpen method does not have to
+** allocate the structure; it should just fill it in.
+**
+** {H11149} 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. {END} The file can be a
+** directory.
+**
+** {H11150} SQLite will always allocate at least mxPathname+1 bytes for the
+** output buffer xFullPathname. {H11151} The exact size of the output buffer
+** is also passed as a parameter to both methods. {END} 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(), and xCurrentTime() 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()

+**
+** A call to sqlite3_initialize() is an "effective" call if it is

+** the process, or if it is the first time sqlite3_initialize() is invoked
+** following a call to sqlite3_shutdown(). Only an effective call
+** of sqlite3_initialize() does any initialization. All other calls
+** are harmless no-ops.
+**
+** Among other things, sqlite3_initialize() shall invoke
+** sqlite3_os_init(). Similarly, sqlite3_shutdown()
+** shall invoke sqlite3_os_end().
+**
+** The sqlite3_initialize() routine returns SQLITE_OK on success.
+** If for some reason, sqlite3_initialize() is unable to initialize
+** the library (perhaps it is unable to allocate a needed resource such
+** as a mutex) it returns an [error code] other than SQLITE_OK.
+**
+** The sqlite3_initialize() routine is called internally by many other
+** SQLite interfaces so that an application usually does not need to
+** invoke sqlite3_initialize() directly. For example, [sqlite3_open()]
+** calls sqlite3_initialize() so the SQLite library will be automatically
+** initialized when [sqlite3_open()] is called if it has not be initialized

+** prior to using any other SQLite interface. For maximum portability,
+** it is recommended that applications always invoke sqlite3_initialize()
+** directly prior to using any other SQLite interface. Future releases
+** of SQLite may require this. In other words, the behavior exhibited
+** when SQLite is compiled with SQLITE_OMIT_AUTOINIT might become the
+** default behavior in some future release of SQLite.
+**
+** The sqlite3_os_init() routine does operating-system specific
+** initialization of the SQLite library. The sqlite3_os_end()

+**
+** The application should never invoke either sqlite3_os_init()

+**
+** This routine sets a callback function that might be invoked whenever

+** or process has locked.
+**
+** If the busy callback is NULL, then [SQLITE_BUSY] or [SQLITE_IOERR_BLOCKED]
+** is returned immediately upon encountering the lock. If the busy callback
+** is not NULL, then the callback will be invoked with two arguments.
+**
+** The first argument to the handler is a copy of the void* pointer which
+** is the third argument to sqlite3_busy_handler(). The second argument to
+** the handler callback is the number of times that the busy handler has
+** been invoked for this locking event. If the
+** busy callback returns 0, then no additional attempts are made to
+** access the database and [SQLITE_BUSY] or [SQLITE_IOERR_BLOCKED] is returned.
+** If the callback returns non-zero, then another attempt
+** is made to open the database for reading and the cycle repeats.
+**
+** The presence of a busy handler does not guarantee that it will be invoked
+** when there is lock contention. If SQLite determines that invoking the busy
+** handler could result in a deadlock, it will go ahead and return [SQLITE_BUSY]
+** or [SQLITE_IOERR_BLOCKED] instead of invoking the busy handler.
+** Consider a scenario where one process is holding a read lock that
+** it is trying to promote to a reserved lock and
+** a second process is holding a reserved lock that it is trying
+** to promote to an exclusive lock. The first process cannot proceed
+** because it is blocked by the second and the second process cannot
+** proceed because it is blocked by the first. If both processes
+** invoke the busy handlers, neither will make any progress. Therefore,
+** SQLite returns [SQLITE_BUSY] for the first process, hoping that this
+** will induce the first process to release its read lock and allow
+** the second process to proceed.
+**
+** The default busy callback is NULL.
+**
+** The [SQLITE_BUSY] error is converted to [SQLITE_IOERR_BLOCKED]
+** when SQLite is in the middle of a large transaction where all the
+** changes will not fit into the in-memory cache. SQLite will
+** already hold a RESERVED lock on the database file, but it needs
+** to promote this lock to EXCLUSIVE so that it can spill cache
+** pages into the database file without harm to concurrent
+** readers. If it is unable to promote the lock, then the in-memory
+** cache will be left in an inconsistent state and so the error
+** code is promoted from the relatively benign [SQLITE_BUSY] to
+** the more severe [SQLITE_IOERR_BLOCKED]. This error code promotion

+**
+** Definition: A <b>result table</b> is memory data structure created by the
+** [sqlite3_get_table()] interface. A result table records the
+** complete query results from one or more queries.
+**
+** The table conceptually has a number of rows and columns. But
+** these numbers are not part of the result table itself. These
+** numbers are obtained separately. Let N be the number of rows
+** and M be the number of columns.
+**
+** A result table is an array of pointers to zero-terminated UTF-8 strings.
+** There are (N+1)*M elements in the array. The first M pointers point
+** to zero-terminated strings that contain the names of the columns.
+** The remaining entries all point to query results. NULL values result
+** in NULL pointers. All other values are in their UTF-8 zero-terminated
+** string representation as returned by [sqlite3_column_text()].
+**
+** A result table might consist of one or more memory allocations.
+** It is not safe to pass a result table directly to [sqlite3_free()].
+** A result table should be deallocated using [sqlite3_free_table()].
+**
+** As an example of the result table format, suppose a query result
+** is as follows:
+**
+** <blockquote><pre>
+** Name | Age
+** -----------------------
+** Alice | 43
+** Bob | 28
+** Cindy | 21
+** </pre></blockquote>
+**
+** There are two column (M==2) and three rows (N==3). Thus the
+** result table has 8 entries. Suppose the result table is stored
+** in an array names azResult. Then azResult holds this content:
+**
+** <blockquote><pre>
+** azResult&#91;0] = "Name";
+** azResult&#91;1] = "Age";
+** azResult&#91;2] = "Alice";
+** azResult&#91;3] = "43";
+** azResult&#91;4] = "Bob";
+** azResult&#91;5] = "28";
+** azResult&#91;6] = "Cindy";
+** azResult&#91;7] = "21";
+** </pre></blockquote>
+**
+** The sqlite3_get_table() function evaluates one or more
+** semicolon-separated SQL statements in the zero-terminated UTF-8
+** string of its 2nd parameter. It returns a result table to the
+** pointer given in its 3rd parameter.
+**
+** After the calling function has finished using the result, it should
+** pass the pointer to the result table to sqlite3_free_table() in order to
+** release the memory that was malloced. Because of the way the
+** [sqlite3_malloc()] happens within sqlite3_get_table(), the calling
+** function must not try to call [sqlite3_free()] directly. Only
+** [sqlite3_free_table()] is able to release the memory properly and safely.
+**
+** The sqlite3_get_table() interface is implemented as a wrapper around
+** [sqlite3_exec()]. The sqlite3_get_table() routine does not have access
+** to any internal data structures of SQLite. It uses only the public

+** CAPI3REF: Formatted String Printing Functions {H17400} <S70000><S20000>
+**
+** These routines are workalikes of the "printf()" family of functions
+** from the standard C library.
+**
+** The sqlite3_mprintf() and sqlite3_vmprintf() routines write their
+** results into memory obtained from [sqlite3_malloc()].
+** The strings returned by these two routines should be
+** released by [sqlite3_free()]. Both routines return a
+** NULL pointer if [sqlite3_malloc()] is unable to allocate enough
+** memory to hold the resulting string.
+**
+** In sqlite3_snprintf() routine is similar to "snprintf()" from
+** the standard C library. The result is written into the
+** buffer supplied as the second parameter whose size is given by
+** the first parameter. Note that the order of the
+** first two parameters is reversed from snprintf(). This is an
+** historical accident that cannot be fixed without breaking
+** backwards compatibility. Note also that sqlite3_snprintf()
+** returns a pointer to its buffer instead of the number of
+** characters actually written into the buffer. We admit that
+** the number of characters written would be a more useful return
+** value but we cannot change the implementation of sqlite3_snprintf()
+** now without breaking compatibility.
+**
+** As long as the buffer size is greater than zero, sqlite3_snprintf()
+** guarantees that the buffer is always zero-terminated. The first
+** parameter "n" is the total size of the buffer, including space for
+** the zero terminator. So the longest string that can be completely
+** written will be n-1 characters.
+**
+** These routines all implement some additional formatting
+** options that are useful for constructing SQL statements.
+** All of the usual printf() formatting options apply. In addition, there
+** is are "%q", "%Q", and "%z" options.
+**
+** The %q option works like %s in that it substitutes a null-terminated
+** string from the argument list. But %q also doubles every '\'' character.
+** %q is designed for use inside a string literal. By doubling each '\''
+** character it escapes that character and allows it to be inserted into
+** the string.
+**
+** For example, assume the string variable zText contains text as follows:
+**
+** <blockquote><pre>
+** char *zText = "It's a happy day!";
+** </pre></blockquote>
+**
+** One can use this text in an SQL statement as follows:
+**
+** <blockquote><pre>
+** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText);
+** sqlite3_exec(db, zSQL, 0, 0, 0);
+** sqlite3_free(zSQL);
+** </pre></blockquote>
+**
+** Because the %q format string is used, the '\'' character in zText
+** is escaped and the SQL generated is as follows:
+**
+** <blockquote><pre>
+** INSERT INTO table1 VALUES('It''s a happy day!')
+** </pre></blockquote>
+**
+** This is correct. Had we used %s instead of %q, the generated SQL
+** would have looked like this:
+**
+** <blockquote><pre>
+** INSERT INTO table1 VALUES('It's a happy day!');
+** </pre></blockquote>
+**
+** This second example is an SQL syntax error. As a general rule you should
+** always use %q instead of %s when inserting text into a string literal.
+**

+** CAPI3REF: Memory Allocation Subsystem {H17300} <S20000>
+**
+** The SQLite core uses these three routines for all of its own
+** internal memory allocation needs. "Core" in the previous sentence
+** does not include operating-system specific VFS implementation. The
+** Windows VFS uses native malloc() and free() for some operations.
+**
+** The sqlite3_malloc() routine returns a pointer to a block
+** of memory at least N bytes in length, where N is the parameter.
+** If sqlite3_malloc() is unable to obtain sufficient free
+** memory, it returns a NULL pointer. If the parameter N to
+** sqlite3_malloc() is zero or negative then sqlite3_malloc() returns
+** a NULL pointer.
+**
+** Calling sqlite3_free() with a pointer previously returned
+** by sqlite3_malloc() or sqlite3_realloc() releases that memory so
+** that it might be reused. The sqlite3_free() routine is
+** a no-op if is called with a NULL pointer. Passing a NULL pointer
+** to sqlite3_free() is harmless. After being freed, memory
+** should neither be read nor written. Even reading previously freed
+** memory might result in a segmentation fault or other severe error.
+** Memory corruption, a segmentation fault, or other severe error
+** might result if sqlite3_free() is called with a non-NULL pointer that
+** was not obtained from sqlite3_malloc() or sqlite3_free().
+**
+** The sqlite3_realloc() interface attempts to resize a
+** prior memory allocation to be at least N bytes, where N is the
+** second parameter. The memory allocation to be resized is the first
+** parameter. If the first parameter to sqlite3_realloc()
+** is a NULL pointer then its behavior is identical to calling
+** sqlite3_malloc(N) where N is the second parameter to sqlite3_realloc().
+** If the second parameter to sqlite3_realloc() is zero or
+** negative then the behavior is exactly the same as calling
+** sqlite3_free(P) where P is the first parameter to sqlite3_realloc().
+** sqlite3_realloc() returns a pointer to a memory allocation
+** of at least N bytes in size or NULL if sufficient memory is unavailable.
+** If M is the size of the prior allocation, then min(N,M) bytes
+** of the prior allocation are copied into the beginning of buffer returned
+** by sqlite3_realloc() and the prior allocation is freed.
+** If sqlite3_realloc() returns NULL, then the prior allocation
+** is not freed.
+**
+** The memory returned by sqlite3_malloc() and sqlite3_realloc()
+** is always aligned to at least an 8 byte boundary. {END}
+**
+** The default implementation of the memory allocation subsystem uses
+** the malloc(), realloc() and free() provided by the standard C library.
+** {H17382} However, if SQLite is compiled with the
+** SQLITE_MEMORY_SIZE=<i>NNN</i> C preprocessor macro (where <i>NNN</i>
+** is an integer), then SQLite create a static array of at least
+** <i>NNN</i> bytes in size and uses that array for all of its dynamic
+** memory allocation needs. {END} Additional memory allocator options
+** may be added in future releases.
+**
+** In SQLite version 3.5.0 and 3.5.1, it was possible to define
+** the SQLITE_OMIT_MEMORY_ALLOCATION which would cause the built-in
+** implementation of these routines to be omitted. That capability
+** is no longer provided. Only built-in memory allocators can be used.
+**
+** The Windows OS interface layer calls
+** the system malloc() and free() directly when converting
+** filenames between the UTF-8 encoding used by SQLite
+** and whatever filename encoding is used by the particular Windows
+** installation. Memory allocation errors are detected, but
+** they are reported back as [SQLITE_CANTOPEN] or
+** [SQLITE_IOERR] rather than [SQLITE_NOMEM].
+**
+** INVARIANTS:
+**
+** {H17303} The [sqlite3_malloc(N)] interface returns either a pointer to

+** that is 8-byte aligned, or it returns NULL if it is unable
+** to fulfill the request.
+**
+** {H17304} The [sqlite3_malloc(N)] interface returns a NULL pointer if
+** N is less than or equal to zero.
+**
+** {H17305} The [sqlite3_free(P)] interface releases memory previously

+**
+** This routine registers a authorizer callback with a particular

+** The authorizer callback is invoked as SQL statements are being compiled
+** by [sqlite3_prepare()] or its variants [sqlite3_prepare_v2()],
+** [sqlite3_prepare16()] and [sqlite3_prepare16_v2()]. At various
+** points during the compilation process, as logic is being created
+** to perform various actions, the authorizer callback is invoked to
+** see if those actions are allowed. The authorizer callback should
+** return [SQLITE_OK] to allow the action, [SQLITE_IGNORE] to disallow the
+** specific action but allow the SQL statement to continue to be
+** compiled, or [SQLITE_DENY] to cause the entire SQL statement to be
+** rejected with an error. If the authorizer callback returns
+** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
+** then the [sqlite3_prepare_v2()] or equivalent call that triggered
+** the authorizer will fail with an error message.
+**
+** When the callback returns [SQLITE_OK], that means the operation

+** a NULL value in place of the table column that would have
+** been read if [SQLITE_OK] had been returned. The [SQLITE_IGNORE]
+** return can be used to deny an untrusted user access to individual
+** columns of a table.
+**
+** The first parameter to the authorizer callback is a copy of the third
+** parameter to the sqlite3_set_authorizer() interface. The second parameter
+** to the callback is an integer [SQLITE_COPY | action code] that specifies
+** the particular action to be authorized. The third through sixth parameters
+** to the callback are zero-terminated strings that contain additional
+** details about the action to be authorized.
+**
+** An authorizer is used when [sqlite3_prepare | preparing]
+** SQL statements from an untrusted source, to ensure that the SQL statements
+** do not try to access data they are not allowed to see, or that they do not
+** try to execute malicious statements that damage the database. For
+** example, an application may allow a user to enter arbitrary
+** SQL queries for evaluation by a database. But the application does
+** not want the user to be able to make arbitrary changes to the
+** database. An authorizer could then be put in place while the
+** user-entered SQL is being [sqlite3_prepare | prepared] that
+** disallows everything except [SELECT] statements.
+**
+** Applications that need to process SQL from untrusted sources
+** might also consider lowering resource limits using [sqlite3_limit()]
+** and limiting database size using the [max_page_count] [PRAGMA]
+** in addition to using an authorizer.
+**
+** Only a single authorizer can be in place on a database connection
+** at a time. Each call to sqlite3_set_authorizer overrides the

+** KEYWORDS: {SQL statement compiler}
+**
+** To execute an SQL query, it must first be compiled into a byte-code
+** program using one of these routines.
+**
+** The first argument, "db", is a [database connection] obtained from a
+** prior call to [sqlite3_open()], [sqlite3_open_v2()] or [sqlite3_open16()].
+**
+** The second argument, "zSql", is the statement to be compiled, encoded
+** as either UTF-8 or UTF-16. The sqlite3_prepare() and sqlite3_prepare_v2()
+** interfaces use UTF-8, and sqlite3_prepare16() and sqlite3_prepare16_v2()
+** use UTF-16.
+**
+** If the nByte argument is less than zero, then zSql is read up to the
+** first zero terminator. If nByte is non-negative, then it is the maximum
+** number of bytes read from zSql. When nByte is non-negative, the
+** zSql string ends at either the first '\000' or '\u0000' character or
+** the nByte-th byte, whichever comes first. If the caller knows
+** that the supplied string is nul-terminated, then there is a small
+** performance advantage to be gained by passing an nByte parameter that
+** is equal to the number of bytes in the input string <i>including</i>
+** the nul-terminator bytes.
+**
+** *pzTail is made to point to the first byte past the end of the
+** first SQL statement in zSql. These routines only compile the first
+** statement in zSql, so *pzTail is left pointing to what remains
+** uncompiled.
+**
+** *ppStmt is left pointing to a compiled [prepared statement] that can be
+** executed using [sqlite3_step()]. If there is an error, *ppStmt is set
+** to NULL. If the input text contains no SQL (if the input is an empty
+** string or a comment) then *ppStmt is set to NULL.
+** {A13018} The calling procedure is responsible for deleting the compiled
+** SQL statement using [sqlite3_finalize()] after it has finished with it.
+**
+** On success, [SQLITE_OK] is returned, otherwise an [error code] is returned.
+**
+** The sqlite3_prepare_v2() and sqlite3_prepare16_v2() interfaces are
+** recommended for all new programs. The two older interfaces are retained
+** for backwards compatibility, but their use is discouraged.
+** In the "v2" interfaces, the prepared statement
+** that is returned (the [sqlite3_stmt] object) contains a copy of the
+** original SQL text. This causes the [sqlite3_step()] interface to
+** behave a differently in two ways:
+**
+** <ol>
+** <li>
+** If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
+** always used to do, [sqlite3_step()] will automatically recompile the SQL
+** statement and try to run it again. If the schema has changed in
+** a way that makes the statement no longer valid, [sqlite3_step()] will still
+** return [SQLITE_SCHEMA]. But unlike the legacy behavior, [SQLITE_SCHEMA] is
+** now a fatal error. Calling [sqlite3_prepare_v2()] again will not make the
+** error go away. Note: use [sqlite3_errmsg()] to find the text
+** of the parsing error that results in an [SQLITE_SCHEMA] return.
+** </li>
+**
+** <li>
+** When an error occurs, [sqlite3_step()] will return one of the detailed
+** [error codes] or [extended error codes]. The legacy behavior was that
+** [sqlite3_step()] would only return a generic [SQLITE_ERROR] result code
+** and you would have to make a second call to [sqlite3_reset()] in order
+** to find the underlying cause of the problem. With the "v2" prepare
+** interfaces, the underlying reason for the error is returned immediately.

+** [sqlite3_prepare_v2()] or its variants.
+**
+** The second argument is the index of the SQL parameter to be set.
+** The leftmost SQL parameter has an index of 1. When the same named
+** SQL parameter is used more than once, second and subsequent
+** occurrences have the same index as the first occurrence.
+** The index for named parameters can be looked up using the
+** [sqlite3_bind_parameter_index()] API if desired. The index
+** for "?NNN" parameters is the value of NNN.
+** The NNN value must be between 1 and the [sqlite3_limit()]
+** parameter [SQLITE_LIMIT_VARIABLE_NUMBER] (default value: 999).
+**
+** The third argument is the value to bind to the parameter.
+**
+** In those routines that have a fourth argument, its value is the
+** number of bytes in the parameter. To be clear: the value is the
+** number of <u>bytes</u> in the value, not the number of characters.
+** If the fourth parameter is negative, the length of the string is
+** the number of bytes up to the first zero terminator.
+**
+** The fifth argument to sqlite3_bind_blob(), sqlite3_bind_text(), and
+** sqlite3_bind_text16() is a destructor used to dispose of the BLOB or
+** string after SQLite has finished with it. If the fifth argument is
+** the special value [SQLITE_STATIC], then SQLite assumes that the
+** information is in static, unmanaged space and does not need to be freed.
+** If the fifth argument has the value [SQLITE_TRANSIENT], then
+** SQLite makes its own private copy of the data immediately, before
+** the sqlite3_bind_*() routine returns.
+**
+** The sqlite3_bind_zeroblob() routine binds a BLOB of length N that
+** is filled with zeroes. A zeroblob uses a fixed amount of memory
+** (just an integer to hold its size) while it is being processed.
+** Zeroblobs are intended to serve as placeholders for BLOBs whose
+** content is later written using
+** [sqlite3_blob_open | incremental BLOB I/O] routines.
+** A negative value for the zeroblob results in a zero-length BLOB.
+**
+** The sqlite3_bind_*() routines must be called after
+** [sqlite3_prepare_v2()] (and its variants) or [sqlite3_reset()] and
+** before [sqlite3_step()].
+** Bindings are not cleared by the [sqlite3_reset()] routine.
+** Unbound parameters are interpreted as NULL.
+**
+** These routines return [SQLITE_OK] on success or an error code if
+** anything goes wrong. [SQLITE_RANGE] is returned if the parameter
+** index is out of range. [SQLITE_NOMEM] is returned if malloc() fails.
+** [SQLITE_MISUSE] might be returned if these routines are called on a
+** virtual machine that is the wrong state or which has already been finalized.
+** Detection of misuse is unreliable. Applications should not depend
+** on SQLITE_MISUSE returns. SQLITE_MISUSE is intended to indicate a
+** a logic error in the application. Future versions of SQLite might
+** panic rather than return SQLITE_MISUSE.

+** [sqlite3_prepare_v2()] and [sqlite3_prepare16_v2()] or the older legacy

+** [SQLITE_DONE], [SQLITE_ROW], [SQLITE_ERROR], or [SQLITE_MISUSE].
+** With the "v2" interface, any of the other [result codes] or
+** [extended result codes] might be returned as well.
+**
+** [SQLITE_BUSY] means that the database engine was unable to acquire the
+** database locks it needs to do its job. If the statement is a [COMMIT]
+** or occurs outside of an explicit transaction, then you can retry the
+** statement. If the statement is not a [COMMIT] and occurs within a
+** explicit transaction then you should rollback the transaction before
+** continuing.
+**
+** [SQLITE_DONE] means that the statement has finished executing
+** successfully. sqlite3_step() should not be called again on this virtual
+** machine without first calling [sqlite3_reset()] to reset the virtual
+** machine back to its initial state.
+**
+** If the SQL statement being executed returns any data, then [SQLITE_ROW]
+** is returned each time a new row of data is ready for processing by the
+** caller. The values may be accessed using the [column access functions].
+** sqlite3_step() is called again to retrieve the next row of data.
+**
+** [SQLITE_ERROR] means that a run-time error (such as a constraint
+** violation) has occurred. sqlite3_step() should not be called again on
+** the VM. More information may be found by calling [sqlite3_errmsg()].
+** With the legacy interface, a more specific error code (for example,

+** can be obtained by calling [sqlite3_reset()] on the
+** [prepared statement]. In the "v2" interface,
+** the more specific error code is returned directly by sqlite3_step().
+**
+** [SQLITE_MISUSE] means that the this routine was called inappropriately.
+** Perhaps it was called on a [prepared statement] that has
+** already been [sqlite3_finalize | finalized] or on one that had
+** previously returned [SQLITE_ERROR] or [SQLITE_DONE]. Or it could
+** be the case that the same database connection is being used by two or

+** [sqlite3_reset()] or [sqlite3_finalize()] in order to find one of the
+** specific [error codes] that better describes the error.
+** We admit that this is a goofy design. The problem has been fixed

+** using either [sqlite3_prepare_v2()] or [sqlite3_prepare16_v2()] instead
+** of the legacy [sqlite3_prepare()] and [sqlite3_prepare16()] interfaces,

+** KEYWORDS: {column access functions}
+**
+** These routines form the "result set query" interface.
+**
+** These routines return information about a single column of the current
+** result row of a query. In every case the first argument is a pointer
+** to the [prepared statement] that is being evaluated (the [sqlite3_stmt*]
+** that was returned from [sqlite3_prepare_v2()] or one of its variants)
+** and the second argument is the index of the column for which information
+** should be returned. The leftmost column of the result set has the index 0.
+**
+** If the SQL statement does not currently point to a valid row, or if the
+** column index is out of range, the result is undefined.
+** These routines may only be called when the most recent call to
+** [sqlite3_step()] has returned [SQLITE_ROW] and neither
+** [sqlite3_reset()] nor [sqlite3_finalize()] have been called subsequently.
+** If any of these routines are called after [sqlite3_reset()] or
+** [sqlite3_finalize()] or after [sqlite3_step()] has returned
+** something other than [SQLITE_ROW], the results are undefined.
+** If [sqlite3_step()] or [sqlite3_reset()] or [sqlite3_finalize()]
+** are called from a different thread while any of these routines
+** are pending, then the results are undefined.
+**
+** The sqlite3_column_type() routine returns the
+** [SQLITE_INTEGER | datatype code] for the initial data type
+** of the result column. The returned value is one of [SQLITE_INTEGER],
+** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL]. The value
+** returned by sqlite3_column_type() is only meaningful if no type
+** conversions have occurred as described below. After a type conversion,
+** the value returned by sqlite3_column_type() is undefined. Future
+** versions of SQLite may change the behavior of sqlite3_column_type()
+** following a type conversion.
+**
+** If the result is a BLOB or UTF-8 string then the sqlite3_column_bytes()
+** routine returns the number of bytes in that BLOB or string.
+** If the result is a UTF-16 string, then sqlite3_column_bytes() converts
+** the string to UTF-8 and then returns the number of bytes.
+** If the result is a numeric value then sqlite3_column_bytes() uses
+** [sqlite3_snprintf()] to convert that value to a UTF-8 string and returns
+** the number of bytes in that string.
+** The value returned does not include the zero terminator at the end
+** of the string. For clarity: the value returned is the number of
+** bytes in the string, not the number of characters.
+**
+** Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
+** even empty strings, are always zero terminated. The return
+** value from sqlite3_column_blob() for a zero-length BLOB is an arbitrary
+** pointer, possibly even a NULL pointer.
+**
+** The sqlite3_column_bytes16() routine is similar to sqlite3_column_bytes()
+** but leaves the result in UTF-16 in native byte order instead of UTF-8.
+** The zero terminator is not included in this count.
+**
+** The object returned by [sqlite3_column_value()] is an
+** [unprotected sqlite3_value] object. An unprotected sqlite3_value object
+** may only be used with [sqlite3_bind_value()] and [sqlite3_result_value()].
+** If the [unprotected sqlite3_value] object returned by
+** [sqlite3_column_value()] is used in any other way, including calls
+** to routines like [sqlite3_value_int()], [sqlite3_value_text()],
+** or [sqlite3_value_bytes()], then the behavior is undefined.
+**
+** These routines attempt to convert the value where appropriate. For
+** example, if the internal representation is FLOAT and a text result
+** is requested, [sqlite3_snprintf()] is used internally to perform the
+** conversion automatically. The following table details the conversions
+** that are applied:
+**
+** <blockquote>
+** <table border="1">
+** <tr><th> Internal<br>Type <th> Requested<br>Type <th> Conversion
+**
+** <tr><td> NULL <td> INTEGER <td> Result is 0
+** <tr><td> NULL <td> FLOAT <td> Result is 0.0
+** <tr><td> NULL <td> TEXT <td> Result is NULL pointer
+** <tr><td> NULL <td> BLOB <td> Result is NULL pointer
+** <tr><td> INTEGER <td> FLOAT <td> Convert from integer to float
+** <tr><td> INTEGER <td> TEXT <td> ASCII rendering of the integer
+** <tr><td> INTEGER <td> BLOB <td> Same as INTEGER->TEXT
+** <tr><td> FLOAT <td> INTEGER <td> Convert from float to integer
+** <tr><td> FLOAT <td> TEXT <td> ASCII rendering of the float
+** <tr><td> FLOAT <td> BLOB <td> Same as FLOAT->TEXT
+** <tr><td> TEXT <td> INTEGER <td> Use atoi()
+** <tr><td> TEXT <td> FLOAT <td> Use atof()
+** <tr><td> TEXT <td> BLOB <td> No change
+** <tr><td> BLOB <td> INTEGER <td> Convert to TEXT then use atoi()
+** <tr><td> BLOB <td> FLOAT <td> Convert to TEXT then use atof()
+** <tr><td> BLOB <td> TEXT <td> Add a zero terminator if needed
+** </table>
+** </blockquote>
+**
+** The table above makes reference to standard C library functions atoi()
+** and atof(). SQLite does not really use these functions. It has its
+** own equivalent internal routines. The atoi() and atof() names are
+** used in the table for brevity and because they are familiar to most
+** C programmers.
+**
+** Note that when type conversions occur, pointers returned by prior
+** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
+** sqlite3_column_text16() may be invalidated.
+** Type conversions and pointer invalidations might occur
+** in the following cases:
+**
+** <ul>
+** <li> The initial content is a BLOB and sqlite3_column_text() or
+** sqlite3_column_text16() is called. A zero-terminator might
+** need to be added to the string.</li>
+** <li> The initial content is UTF-8 text and sqlite3_column_bytes16() or
+** sqlite3_column_text16() is called. The content must be converted
+** to UTF-16.</li>
+** <li> The initial content is UTF-16 text and sqlite3_column_bytes() or
+** sqlite3_column_text() is called. The content must be converted
+** to UTF-8.</li>
+** </ul>
+**
+** Conversions between UTF-16be and UTF-16le are always done in place and do
+** not invalidate a prior pointer, though of course the content of the buffer
+** that the prior pointer points to will have been modified. Other kinds
+** of conversion are done in place when it is possible, but sometimes they
+** are not possible and in those cases prior pointers are invalidated.
+**
+** The safest and easiest to remember policy is to invoke these routines
+** in one of the following ways:
+**
+** <ul>
+** <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
+** <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
+** <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
+** </ul>
+**
+** In other words, you should call sqlite3_column_text(),
+** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
+** into the desired format, then invoke sqlite3_column_bytes() or
+** sqlite3_column_bytes16() to find the size of the result. Do not mix calls
+** to sqlite3_column_text() or sqlite3_column_blob() with calls to
+** sqlite3_column_bytes16(), and do not mix calls to sqlite3_column_text16()
+** with calls to sqlite3_column_bytes().
+**
+** The pointers returned are valid until a type conversion occurs as
+** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
+** [sqlite3_finalize()] is called. The memory space used to hold strings
+** and BLOBs is freed automatically. Do <b>not</b> pass the pointers returned
+** [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
+** [sqlite3_free()].
+**
+** If a memory allocation error occurs during the evaluation of any
+** of these routines, a default value is returned. The default value
+** is either the integer 0, the floating point number 0.0, or a NULL
+** pointer. Subsequent calls to [sqlite3_errcode()] will return
+** [SQLITE_NOMEM].

+**
+** These two functions (collectively known as "function creation routines")
+** are used to add SQL functions or aggregates or to redefine the behavior
+** of existing SQL functions or aggregates. The only difference between the
+** two is that the second parameter, the name of the (scalar) function or
+** aggregate, is encoded in UTF-8 for sqlite3_create_function() and UTF-16
+** for sqlite3_create_function16().
+**
+** The first parameter is the [database connection] to which the SQL
+** function is to be added. If a single program uses more than one database
+** connection internally, then SQL functions must be added individually to
+** each database connection.
+**
+** The second parameter is the name of the SQL function to be created or
+** redefined. The length of the name is limited to 255 bytes, exclusive of
+** the zero-terminator. Note that the name length limit is in bytes, not
+** characters. Any attempt to create a function with a longer name
+** will result in [SQLITE_ERROR] being returned.
+**
+** The third parameter is the number of arguments that the SQL function or
+** aggregate takes. If this parameter is negative, then the SQL function or
+** aggregate may take any number of arguments.
+**
+** The fourth parameter, eTextRep, specifies what
+** [SQLITE_UTF8 | text encoding] this SQL function prefers for
+** its parameters. Any SQL function implementation should be able to work
+** work with UTF-8, UTF-16le, or UTF-16be. But some implementations may be
+** more efficient with one encoding than another. It is allowed to
+** invoke sqlite3_create_function() or sqlite3_create_function16() multiple
+** times with the same function but with different values of eTextRep.
+** When multiple implementations of the same function are available, SQLite
+** will pick the one that involves the least amount of data conversion.
+** If there is only a single implementation which does not care what text
+** encoding is used, then the fourth argument should be [SQLITE_ANY].
+**
+** The fifth parameter is an arbitrary pointer. The implementation of the
+** function can gain access to this pointer using [sqlite3_user_data()].
+**
+** The seventh, eighth and ninth parameters, xFunc, xStep and xFinal, are
+** pointers to C-language functions that implement the SQL function or
+** aggregate. A scalar SQL function requires an implementation of the xFunc
+** callback only, NULL pointers should be passed as the xStep and xFinal
+** parameters. An aggregate SQL function requires an implementation of xStep
+** and xFinal and NULL should be passed for xFunc. To delete an existing
+** SQL function or aggregate, pass NULL for all three function callbacks.
+**
+** It is permitted to register multiple implementations of the same
+** functions with the same name but with either differing numbers of
+** arguments or differing preferred text encodings. SQLite will use

+** [sqlite3_create_function()] and [sqlite3_create_function16()]
+** for additional information.
+**
+** These functions work very much like the [parameter binding] family of
+** functions used to bind values to host parameters in prepared statements.
+** Refer to the [SQL parameter] documentation for additional information.
+**
+** The sqlite3_result_blob() interface sets the result from
+** an application-defined function to be the BLOB whose content is pointed
+** to by the second parameter and which is N bytes long where N is the
+** third parameter.
+**
+** The sqlite3_result_zeroblob() interfaces set the result of
+** the application-defined function to be a BLOB containing all zero
+** bytes and N bytes in size, where N is the value of the 2nd parameter.
+**
+** The sqlite3_result_double() interface sets the result from
+** an application-defined function to be a floating point value specified
+** by its 2nd argument.
+**
+** The sqlite3_result_error() and sqlite3_result_error16() functions
+** cause the implemented SQL function to throw an exception.
+** SQLite uses the string pointed to by the
+** 2nd parameter of sqlite3_result_error() or sqlite3_result_error16()
+** as the text of an error message. SQLite interprets the error
+** message string from sqlite3_result_error() as UTF-8. SQLite
+** interprets the string from sqlite3_result_error16() as UTF-16 in native
+** byte order. If the third parameter to sqlite3_result_error()
+** or sqlite3_result_error16() is negative then SQLite takes as the error
+** message all text up through the first zero character.
+** If the third parameter to sqlite3_result_error() or
+** sqlite3_result_error16() is non-negative then SQLite takes that many
+** bytes (not characters) from the 2nd parameter as the error message.
+** The sqlite3_result_error() and sqlite3_result_error16()
+** routines make a private copy of the error message text before
+** they return. Hence, the calling function can deallocate or
+** modify the text after they return without harm.
+** The sqlite3_result_error_code() function changes the error code
+** returned by SQLite as a result of an error in a function. By default,
+** the error code is SQLITE_ERROR. A subsequent call to sqlite3_result_error()
+** or sqlite3_result_error16() resets the error code to SQLITE_ERROR.
+**
+** The sqlite3_result_toobig() interface causes SQLite to throw an error
+** indicating that a string or BLOB is to long to represent.
+**
+** The sqlite3_result_nomem() interface causes SQLite to throw an error
+** indicating that a memory allocation failed.
+**
+** The sqlite3_result_int() interface sets the return value
+** of the application-defined function to be the 32-bit signed integer
+** value given in the 2nd argument.
+** The sqlite3_result_int64() interface sets the return value
+** of the application-defined function to be the 64-bit signed integer
+** value given in the 2nd argument.
+**
+** The sqlite3_result_null() interface sets the return value
+** of the application-defined function to be NULL.
+**
+** The sqlite3_result_text(), sqlite3_result_text16(),
+** sqlite3_result_text16le(), and sqlite3_result_text16be() interfaces
+** set the return value of the application-defined function to be
+** a text string which is represented as UTF-8, UTF-16 native byte order,
+** UTF-16 little endian, or UTF-16 big endian, respectively.
+** SQLite takes the text result from the application from
+** the 2nd parameter of the sqlite3_result_text* interfaces.
+** If the 3rd parameter to the sqlite3_result_text* interfaces
+** is negative, then SQLite takes result text from the 2nd parameter
+** through the first zero character.
+** If the 3rd parameter to the sqlite3_result_text* interfaces
+** is non-negative, then as many bytes (not characters) of the text
+** pointed to by the 2nd parameter are taken as the application-defined
+** function result.
+** If the 4th parameter to the sqlite3_result_text* interfaces
+** or sqlite3_result_blob is a non-NULL pointer, then SQLite calls that
+** function as the destructor on the text or BLOB result when it has
+** finished using that result.
+** If the 4th parameter to the sqlite3_result_text* interfaces or
+** sqlite3_result_blob is the special constant SQLITE_STATIC, then SQLite
+** assumes that the text or BLOB result is in constant space and does not
+** copy the it or call a destructor when it has finished using that result.
+** If the 4th parameter to the sqlite3_result_text* interfaces
+** or sqlite3_result_blob is the special constant SQLITE_TRANSIENT
+** then SQLite makes a copy of the result into space obtained from
+** from [sqlite3_malloc()] before it returns.
+**
+** The sqlite3_result_value() interface sets the result of

+** CAPI3REF: Write Data Into A BLOB Incrementally {H17870} <S30230>
+**
+** This function is used to write data into an open [BLOB handle] from a
+** caller-supplied buffer. N bytes of data are copied from the buffer Z
+** into the open BLOB, starting at offset iOffset.
+**
+** If the [BLOB handle] passed as the first argument was not opened for
+** writing (the flags parameter to [sqlite3_blob_open()] was zero),
+** this function returns [SQLITE_READONLY].
+**
+** This function may only modify the contents of the BLOB; it is
+** not possible to increase the size of a BLOB using this API.
+** If offset iOffset is less than N bytes from the end of the BLOB,
+** [SQLITE_ERROR] is returned and no data is written. If N is
+** less than zero [SQLITE_ERROR] is returned and no data is written.
+**
+** An attempt to write to an expired [BLOB handle] fails with an
+** error code of [SQLITE_ABORT]. Writes to the BLOB that occurred
+** before the [BLOB handle] expired are not rolled back by the
+** expiration of the handle, though of course those changes might
+** have been overwritten by the statement that expired the BLOB handle
+** or by other independent statements.
+**
+** On success, SQLITE_OK is returned.
+** Otherwise, an [error code] or an [extended error code] is returned.
+**
+** INVARIANTS:
+**
+** {H17873} A successful invocation of [sqlite3_blob_write(P,Z,N,X)]
+** shall write N bytes of data from buffer Z into the BLOB
+** referenced by [BLOB handle] P beginning at offset X into
+** the BLOB.
+**
+** {H17874} In the absence of other overridding changes, the changes
+** written to a BLOB by [sqlite3_blob_write()] shall
+** remain in effect after the associated [BLOB handle] expires.
+**
+** {H17875} If the [BLOB handle] P was opened for reading only then
+** an invocation of [sqlite3_blob_write(P,Z,N,X)] shall leave
+** the referenced BLOB unchanged and return [SQLITE_READONLY].
+**
+** {H17876} If the size of the BLOB referenced by [BLOB handle] P is

+**
+** A virtual filesystem (VFS) is an [sqlite3_vfs] object

+** To make an existing VFS into the default VFS, register it again
+** with the makeDflt flag set. If two different VFSes with the
+** same name are registered, the behavior is undefined. If a
+** VFS is registered with a name that is NULL or an empty string,
+** then the behavior is undefined.
+**
+** Unregister a VFS with the sqlite3_vfs_unregister() interface.

+** CAPI3REF: Mutexes {H17000} <S20000>
+**
+** The SQLite core uses these routines for thread
+** synchronization. Though they are intended for internal
+** use by SQLite, code that links against SQLite is
+** permitted to use any of these routines.
+**
+** The SQLite source code contains multiple implementations
+** of these mutex routines. An appropriate implementation
+** is selected automatically at compile-time. The following
+** implementations are available in the SQLite core:
+**
+** <ul>
+** <li> SQLITE_MUTEX_OS2
+** <li> SQLITE_MUTEX_PTHREAD
+** <li> SQLITE_MUTEX_W32
+** <li> SQLITE_MUTEX_NOOP
+** </ul>
+**
+** The SQLITE_MUTEX_NOOP implementation is a set of routines
+** that does no real locking and is appropriate for use in
+** a single-threaded application. The SQLITE_MUTEX_OS2,
+** SQLITE_MUTEX_PTHREAD, and SQLITE_MUTEX_W32 implementations
+** are appropriate for use on OS/2, Unix, and Windows.
+**
+** If SQLite is compiled with the SQLITE_MUTEX_APPDEF preprocessor
+** macro defined (with "-DSQLITE_MUTEX_APPDEF=1"), then no mutex
+** implementation is included with the library. In this case the
+** application must supply a custom mutex implementation using the
+** [SQLITE_CONFIG_MUTEX] option of the sqlite3_config() function
+** before calling sqlite3_initialize() or any other public sqlite3_
+** function that calls sqlite3_initialize().
+**
+** {H17011} The sqlite3_mutex_alloc() routine allocates a new
+** mutex and returns a pointer to it. {H17012} If it returns NULL
+** that means that a mutex could not be allocated. {H17013} SQLite
+** will unwind its stack and return an error. {H17014} The argument
+** to sqlite3_mutex_alloc() is one of these integer constants:
+**
+** <ul>
+** <li> SQLITE_MUTEX_FAST
+** <li> SQLITE_MUTEX_RECURSIVE
+** <li> SQLITE_MUTEX_STATIC_MASTER
+** <li> SQLITE_MUTEX_STATIC_MEM
+** <li> SQLITE_MUTEX_STATIC_MEM2
+** <li> SQLITE_MUTEX_STATIC_PRNG
+** <li> SQLITE_MUTEX_STATIC_LRU
+** <li> SQLITE_MUTEX_STATIC_LRU2
+** </ul>
+**
+** {H17015} The first two constants cause sqlite3_mutex_alloc() to create
+** a new mutex. The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
+** is used but not necessarily so when SQLITE_MUTEX_FAST is used. {END}
+** The mutex implementation does not need to make a distinction
+** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
+** not want to. {H17016} But SQLite will only request a recursive mutex in
+** cases where it really needs one. {END} If a faster non-recursive mutex
+** implementation is available on the host platform, the mutex subsystem
+** might return such a mutex in response to SQLITE_MUTEX_FAST.
+**
+** {H17017} The other allowed parameters to sqlite3_mutex_alloc() each return
+** a pointer to a static preexisting mutex. {END} Four static mutexes are
+** used by the current version of SQLite. Future versions of SQLite
+** may add additional static mutexes. Static mutexes are for internal
+** use by SQLite only. Applications that use SQLite mutexes should
+** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
+** SQLITE_MUTEX_RECURSIVE.
+**
+** {H17018} Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
+** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
+** returns a different mutex on every call. {H17034} But for the static
+** mutex types, the same mutex is returned on every call that has
+** the same type number.
+**
+** {H17019} The sqlite3_mutex_free() routine deallocates a previously
+** allocated dynamic mutex. {H17020} SQLite is careful to deallocate every
+** dynamic mutex that it allocates. {A17021} The dynamic mutexes must not be in
+** use when they are deallocated. {A17022} Attempting to deallocate a static
+** mutex results in undefined behavior. {H17023} SQLite never deallocates
+** a static mutex. {END}
+**
+** The sqlite3_mutex_enter() and sqlite3_mutex_try() routines attempt
+** to enter a mutex. {H17024} If another thread is already within the mutex,
+** sqlite3_mutex_enter() will block and sqlite3_mutex_try() will return
+** SQLITE_BUSY. {H17025} The sqlite3_mutex_try() interface returns [SQLITE_OK]
+** upon successful entry. {H17026} Mutexes created using
+** SQLITE_MUTEX_RECURSIVE can be entered multiple times by the same thread.
+** {H17027} In such cases the,
+** mutex must be exited an equal number of times before another thread
+** can enter. {A17028} If the same thread tries to enter any other
+** kind of mutex more than once, the behavior is undefined.
+** {H17029} SQLite will never exhibit
+** such behavior in its own use of mutexes.
+**
+** Some systems (for example, Windows 95) do not support the operation
+** implemented by sqlite3_mutex_try(). On those systems, sqlite3_mutex_try()
+** will always return SQLITE_BUSY. {H17030} The SQLite core only ever uses
+** sqlite3_mutex_try() as an optimization so this is acceptable behavior.
+**
+** {H17031} The sqlite3_mutex_leave() routine exits a mutex that was
+** previously entered by the same thread. {A17032} The behavior
+** is undefined if the mutex is not currently entered by the
+** calling thread or is not currently allocated. {H17033} SQLite will
+** never do either. {END}

+**
+** <dt>SQLITE_STATUS_SCRATCH_OVERFLOW</dt>
+** <dd>This parameter returns the number of bytes of scratch memory
+** allocation which could not be statisfied by the [SQLITE_CONFIG_SCRATCH]
+** buffer and where forced to overflow to [sqlite3_malloc()]. The values
+** returned include overflows because the requested allocation was too
+** larger (that is, because the requested allocation was larger than the
+** "sz" parameter to [SQLITE_CONFIG_SCRATCH]) and because no scratch buffer
+** slots were available.
+** </dd>
+**
+** <dt>SQLITE_STATUS_SCRATCH_SIZE</dt>
+** <dd>This parameter records the largest memory allocation request
+** handed to [scratch memory allocator]. Only the value returned in the
+** *pHighwater parameter to [sqlite3_status()] is of interest.
+** The value written into the *pCurrent parameter is undefined.</dd>
+**
+** <dt>SQLITE_STATUS_PARSER_STACK</dt>
+** <dd>This parameter records the deepest parser stack. It is only
+** meaningful if SQLite is compiled with [YYTRACKMAXSTACKDEPTH].</dd>
