******************************************************************************
**
** This file implements a VFS shim that writes a checksum on each page
** of an SQLite database file. When reading pages, the checksum is verified
** and an error is raised if the checksum is incorrect.
**
** COMPILING
**
** This extension requires SQLite 3.32.0 or later. It uses the
** sqlite3_database_file_object() interface which was added in
** version 3.32.0, so it will not link with an earlier version of
** SQLite.
**
** To build this extension as a separately loaded shared library or
** DLL, use compiler command-lines similar to the following:
**
** (linux) gcc -fPIC -shared cksumvfs.c -o cksumvfs.so
** (mac) clang -fPIC -dynamiclib cksumvfs.c -o cksumvfs.dylib
** (windows) cl cksumvfs.c -link -dll -out:cksumvfs.dll
**
** You may want to add additional compiler options, of course,
** according to the needs of your project.
**
** If you want to statically link this extension with your product,
** then compile it like any other C-language module but add the
** "-DSQLITE_CKSUMVFS_STATIC" option so that this module knows that
** it is being statically linked rather than dynamically linked
**
** LOADING
**
** To load this extension as a shared library, you first have to
** bring up a dummy SQLite database connection to use as the argument
** to the sqlite3_load_extension() API call. Then you invoke the
** sqlite3_load_extension() API and shutdown the dummy database
** connection. All subsequent database connections that are opened
** will include this extension. For example:
**
** sqlite3 *db;
** sqlite3_open(":memory:", &db);
** sqlite3_load_extention(db, "./cksumvfs");
** sqlite3_close(db);
**
** If this extension is compiled with -DSQLITE_CKSUMVFS_STATIC and
** statically linked against the application, initialize it using
** a single API call as follows:
**
** sqlite3_cksumvfs_init();
**
** Cksumvfs is a VFS Shim. When loaded, "cksmvfs" becomes the new
** default VFS and it uses the prior default VFS as the next VFS
** down in the stack. This is normally what you want. However, it
** complex situations where multiple VFS shims are being loaded,
** it might be important to ensure that cksumvfs is loaded in the
** correct order so that it sequences itself into the default VFS
** Shim stack in the right order.
**
** USING
**
** Open database connections using the sqlite3_open() or
** sqlite3_open_v2() interfaces, as normal. Ordinary database files
** (without a checksum) will operate normally. Databases with
** checksums will return an SQLITE_IOERR_DATA error if a page is
** encountered that contains an invalid checksum.
**
** Checksumming only works on databases that have a reserve-bytes
** value of exactly 8. The default value for reserve-bytes is 0.
** Hence, newly created database files will omit the checksum by
** default. To create a database that includes a checksum, change
** the reserve-bytes value to 8 by runing:
**
** int n = 8;
** sqlite3_file_control(db, 0, SQLITE_FCNTL_RESERVED_BYTES, &n);
**
** If you do this immediately after creating a new database file,
** before anything else has been written into the file, then that
** might be all that you need to do. Otherwise, the API call
** above should be followed by:
**
** sqlite3_exec(db, "VACUUM", 0, 0, 0);
**
** It never hurts to run the VACUUM, even if you don't need it.
** If the database is in WAL mode, you should shutdown and
** reopen all database connections before continuing.
**
** From the CLI, use the ".filectrl reserve_bytes 8" command,
** followed by "VACUUM;".
**
** Note that SQLite allows the number of reserve-bytes to be
** increased but not decreased. So if a database file already
** has a reserve-bytes value greater than 8, there is no way to
** activate checksumming on that database, other than to dump
** and restore the database file. Note also that other extensions
** might also make use of the reserve-bytes. Checksumming will
** be incompatible with those other extensions.
**
** VERIFICATION OF CHECKSUMS
**
** If any checksum is incorrect, the "PRAGMA quick_check" command
** will find it. To verify that checksums are actually enabled
** and running, use the following query:
**
** SELECT count(*), verify_checksum(data)
** FROM sqlite_dbpage
** GROUP BY 2;
**
** There are three possible outputs form the verify_checksum()
** function: 1, 0, and NULL. 1 is returned if the checksum is
** correct. 0 is returned if the checksum is incorrect. NULL
** is returned if the page is unreadable. If checksumming is
** enabled, the read will fail if the checksum is wrong, so the
** usual result from verify_checksum() on a bad checksum is NULL.
**
** If everything is OK, the query above should return a single
** row where the second column is 1. Any other result indicates
** either that there is a checksum error, or checksum validation
** is disabled.
**
** CONTROLLING CHECKSUM VERIFICATION
**
** The cksumvfs extension implements a new PRAGMA statement that can
** be used to disable, re-enable, or query the status of checksum
** verification:
**
** PRAGMA checksum_verification; -- query status
** PRAGMA checksum_verification=OFF; -- disable verification
** PRAGMA checksum_verification=ON; -- re-enable verification
**
** The "checksum_verification" pragma will return "1" (true) or "0"
** (false) if checksum verification is enabled or disabled, respectively.
** "Verification" in this context means the feature that causes
** SQLITE_IOERR_DATA errors if a checksum mismatch is detected while
** reading. Checksums are always kept up-to-date as long as the
** reserve-bytes value of the database is 8, regardless of the setting
** of this pragma. Checksum verification can be disabled (for example)
** to do forensic analysis of a database that has previously reported
** a checksum error.
**
** The "checksum_verification" pragma will always respond with "0" if
** the database file does not have a reserve-bytes value of 8. The
** pragma will return no rows at all if the cksumvfs extension is
** not loaded.
**
** IMPLEMENTATION NOTES
**
** The checksum is stored in the last 8 bytes of each page. This
** module only operates if the "bytes of reserved space on each page"
** value at offset 20 the SQLite database header is exactly 8. If
** the reserved-space value is not 8, this module is a no-op.
