The SQLite VACUUM operation ** will renumber such rowids, thereby breaking fts2. If you are using ** fts2 in a system which has disabled VACUUM, then you can continue ** to use it safely. Note that PRAGMA auto_vacuum does NOT disable ** VACUUM, though systems using auto_vacuum are unlikely to invoke ** VACUUM. ** ** Unlike fts1, which is safe across VACUUM if you never delete ** documents, fts2 has a second exposure to this flaw, in the segments ** table. So fts2 should be considered unsafe across VACUUM in all ** cases. */ /* ** 2006 Oct 10 ** ** The author disclaims copyright to this source code.

The name must ** be unique across all VFS modules. ** ** SQLite will guarantee that the zFilename string passed to ** xOpen() is a full pathname as generated by xFullPathname() and ** that the string will be valid and unchanged until xClose() is ** called. So the [sqlite3_file] can store a pointer to the ** filename if it needs to remember the filename for some reason. ** ** The flags argument to xOpen() is a copy of the flags argument ** to [sqlite3_open_v2()]. If [sqlite3_open()] or [sqlite3_open16()] ** is used, then flags is [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_MASTER_JOURNAL] ** </ul> ** ** The file I/O implementation can use the object type flags to ** changes 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 are ** also a no-op. Any attempt to read the journal return SQLITE_IOERR. ** Or the implementation might recognize the 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. This will always be set for TEMP ** databases and journals and for subjournals. 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. ** ** Space to hold the [sqlite3_file] structure passed as the third ** argument to xOpen is allocated by caller (the SQLite core). ** szOsFile bytes are allocated for this object. The xOpen method ** fills in the allocated space. ** ** The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS] ** to test for the existance of a file, ** or [SQLITE_ACCESS_READWRITE] to test to see ** if a file is readable and writable, or [SQLITE_ACCESS_READ] ** to test to see if a file is at least readable. The file can be a ** directory. ** ** SQLite will always allocate at least mxPathname+1 byte for ** the output buffers for xGetTempname and 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. As this is handled as a fatal error by SQLite, ** vfs implementations should endevour 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.

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. The ** mutex interface routines defined here become external ** references in the SQLite library for which implementations ** must be provided by the application. This facility allows an ** application that links against SQLite to provide its own mutex ** implementation without having to modify the SQLite core. ** ** The sqlite3_mutex_alloc() routine allocates a new ** mutex and returns a pointer to it. If it returns NULL ** that means that a mutex could not be allocated. SQLite ** will unwind its stack and return an error. 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 ** </ul> ** ** 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. ** The mutex implementation does not need to make a distinction ** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does ** not want to. But SQLite will only request a recursive mutex in ** cases where it really needs one. 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. ** ** The other allowed parameters to sqlite3_mutex_alloc() each return ** a pointer to a static preexisting mutex. 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. ** ** 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. But for the static ** mutex types, the same mutex is returned on every call that has ** the same type number. ** ** The sqlite3_mutex_free() routine deallocates a previously ** allocated dynamic mutex. SQLite is careful to deallocate every ** dynamic mutex that it allocates. The dynamic mutexes must not be in ** use when they are deallocated. Attempting to deallocate a static ** mutex results in undefined behavior. SQLite never deallocates ** a static mutex. ** ** The sqlite3_mutex_enter() and sqlite3_mutex_try() routines attempt ** to enter a mutex.

In such cases the, ** mutex must be exited an equal number of times before another thread ** can enter. If the same thread tries to enter any other kind of mutex ** more than once, the behavior is undefined.
