SQLite Release Version 3.7.9

Changelog:
If a search token (on the right-hand side of the MATCH operator) in FTS4 begins with "^" then that token must be the first in its field of the document. ** Potentially Incompatible Change **
Added options SQLITE_DBSTATUS_CACHE_HIT and SQLITE_DBSTATUS_CACHE_MISS to the sqlite3_db_status() interface.
Removed support for SQLITE_ENABLE_STAT2, replacing it with the much more capable SQLITE_ENABLE_STAT3 option.
Enhancements to the sqlite3_analyzer utility program, including the --pageinfo and --stats options and support for multiplexed databases.
Enhance the sqlite3_data_count() interface so that it can be used to determine if SQLITE_DONE has been seen on the prepared statement.
Added the SQLITE_FCNTL_OVERWRITE file-control by which the SQLite core indicates to the VFS that the current transaction will overwrite the entire database file.
Increase the default lookaside memory allocator allocation size from 100 to 128 bytes.
Enhanced the query planner so that it can factor terms in and out of OR expressions in the WHERE clause in an effort to find better indices.
Added the SQLITE_DIRECT_OVERFLOW_READ compile-time option, causing overflow pages to be read directly from the database file, bypassing the page cache.
Remove limits on the magnitude of precision and width value in the format specifiers of the sqlite3_mprintf() family of string rendering routines.
Fix a bug that prevent ALTER TABLE ... RENAME from working on some virtual tables in a database with a UTF16 encoding.
Fix a bug in ASCII-to-float conversion that causes slow performance and incorrect results when converting numbers with ridiculously large exponents.
Fix a bug that causes incorrect results in aggregate queries that use multiple aggregate functions whose arguments contain complicated expressions that differ only in the case of string literals contained within those expressions.
Fix a bug that prevented the page_count and quick_check pragmas from working correctly if their names were capitalized.
Fix a bug that caused VACUUM to fail if the count_changes pragma was engaged.
Fix a bug in virtual table implementation that causes a crash if an FTS4 table is dropped inside a transaction and a SAVEPOINT occurs afterwards.

SQLite Release 3.7.10

Changelog:
  • The default schema format number is changed from 1 to 4. This means that, unless the PRAGMA legacy_file_format=ON statement is run, newly created database files will be unreadable by version of SQLite prior to 3.3.0 (2006-01-10). It also means that the descending indices are enabled by default.
  • The sqlite3_pcache_methods structure and the SQLITE_CONFIG_PCACHE and SQLITE_CONFIG_GETPCACHE configuration parameters are deprecated. They are replaced by a new sqlite3_pcache_methods2 structure and SQLITE_CONFIG_PCACHE2 and SQLITE_CONFIG_GETPCACHE2 configuration parameters.
  • Added the powersafe overwrite property to the VFS interface. Provide the SQLITE_IOCAP_POWERSAFE_OVERWRITE I/O capability, the SQLITE_POWERSAFE_OVERWRITE compile-time option, and the "psow=BOOLEAN" query parameter for URI filenames.
  • Added the sqlite3_db_release_memory() interface and the shrink_memory pragma.
  • Added the sqlite3_db_filename() interface.
  • Added the sqlite3_stmt_busy() interface.
  • Added the sqlite3_uri_boolean() and sqlite3_uri_int64() interfaces.
  • If the argument to PRAGMA cache_size is negative N, that means to use approximately -1024*N bytes of memory for the page cache regardless of the page size.
  • Enhanced the default memory allocator to make use of _msize() on windows, malloc_size() on Mac, and malloc_usable_size() on Linux.
  • Enhanced the query planner to support index queries with range constraints on the rowid.
  • Enhanced the query planner flattening logic to allow UNION ALL compounds to be promoted upwards to replace a simple wrapper SELECT even if the compounds are joins.
  • Enhanced the query planner so that the xfer optimization can be used with INTEGER PRIMARY KEY ON CONFLICT as long as the destination table is initially empty.
  • Enhanced the windows VFS so that all system calls can be overridden using the xSetSystemCall interface.
  • Updated the "unix-dotfile" VFS to use locking directories with mkdir() and rmdir() instead of locking files with open() and unlink().
  • Enhancements to the test_quota.c extension to support stdio-like interfaces with quotas.
  • Change the unix VFS to be tolerant of read() system calls that return less then the full number of requested bytes.
  • Change both unix and windows VFSes to report a sector size of 4096 instead of the old default of 512.
  • In the TCL Interface, add the -uri option to the "sqlite3" TCL command used for creating new database connection objects.
  • Added the SQLITE_TESTCTRL_EXPLAIN_STMT test-control option with the SQLITE_ENABLE_TREE_EXPLAIN compile-time option to enable the command-line shell to display ASCII-art parse trees of SQL statements that it processes, for debugging and analysis.
  • Bug fix: Add an additional xSync when restarting a WAL in order to prevent an exceedingly unlikely but theoretically possible database corruption following power-loss. Ticket ff5be73dee.
  • Bug fix: Change the VDBE so that all registers are initialized to Invalid instead of NULL. Ticket 7bbfb7d442
  • Bug fix: Fix problems that can result from 32-bit integer overflow. Ticket ac00f496b7e2
  • SQLITE_SOURCE_ID: "2012-01-16 13:28:40 ebd01a8deffb5024a5d7494eef800d2366d97204"

SQLite 3.7.11

Changelog:
Enhance the INSERT syntax to allow multiple rows to be inserted via the VALUES clause.
Enhance the CREATE VIRTUAL TABLE command to support the IF NOT EXISTS clause.
Added the sqlite3_stricmp() interface as a counterpart to sqlite3_strnicmp().
Added the sqlite3_db_readonly() interface.
Added the SQLITE_FCNTL_PRAGMA file control, giving VFS implementations the ability to add new PRAGMA statements or to override built-in PRAGMAs.
Queries of the form: "SELECT max(x), y FROM table" returns the value of y on the same row that contains the maximum x value.
Added support for the FTS4 languageid option.
Documented support for the FTS4 content option. This feature has actually been in the code since version 3.7.9 but is only now considered to be officially supported.
Pending statements no longer block ROLLBACK. Instead, the pending statement will return SQLITE_ABORT upon next access after the ROLLBACK.
Improvements to the handling of CSV inputs in the command-line shell
Fix a bug introduced in version 3.7.10 that might cause a LEFT JOIN to be incorrectly converted into an INNER JOIN if the WHERE clause indexable terms connected by OR.

SQLite 3.7.12

Changelog:
  • Add the SQLITE_DBSTATUS_CACHE_WRITE option for sqlite3_db_status().
  • Optimize the typeof() and length() SQL functions so that they avoid unnecessary reading of database content from disk.
  • Add the FTS4 "merge" command, the FTS4 "automerge" command, and the FTS4 "integrity-check" command.
  • Report the name of specific CHECK constraints that fail.
  • In the command-line shell, use popen() instead of fopen() if the first character of the argument to the ".output" command is "|".
  • Make use of OVERLAPPED in the windows VFS to avoid some system calls and thereby obtain a performance improvement.
  • More aggressive optimization of the AND operator when one side or the other is always false.
  • Improved performance of queries with many OR-connected terms in the WHERE clause that can all be indexed.
  • Add the SQLITE_RTREE_INT_ONLY compile-time option to force the R*Tree Extension Module to use integer instead of floating point values for both storage and computation.
  • Enhance the PRAGMA integrity_check command to use much less memory when processing multi-gigabyte databases.
  • New interfaces added to the test_quota.c add-on module.
  • Added the ".trace" dot-command to the command-line shell.
  • Allow virtual table constructors to be invoked recursively.
  • Improved optimization of ORDER BY clauses on compound queries.
  • Improved optimization of aggregate subqueries contained within an aggregate query.
  • Bug fix: Fix the RELEASE command so that it does not cancel pending queries. This repairs a problem introduced in 3.7.11.
  • Bug fix: Do not discard the DISTINCT as superfluous unless a subset of the result set is subject to a UNIQUE constraint and it none of the columns in that subset can be NULL. Ticket 385a5b56b9.
  • Bug fix: Do not optimize away an ORDER BY clause that has the same terms as a UNIQUE index unless those terms are also NOT NULL. Ticket 2a5629202f.
  • SQLITE_SOURCE_ID: "2012-05-14 01:41:23 8654aa9540fe9fd210899d83d17f3f407096c004"

SQLite 3.7.13

Changelog:
  • In-memory databases that are specified using URI filenames are allowed to use shared cache, so that the same in-memory database can be accessed from multiple database connections.
  • Recognize and use the mode=memory query parameter in URI filenames.
  • Avoid resetting the schema of shared cache connections when any one connection closes. Instead, wait for the last connection to close before reseting the schema.
  • In the RTREE extension, when rounding 64-bit floating point numbers to 32-bit for storage, always round in a direction that causes the bounding box to get larger.
  • Adjust the unix driver to avoid unnecessary calls to fchown().
  • Add interfaces sqlite3_quota_ferror() and sqlite3_quota_file_available() to the test_quota.c module.
  • The sqlite3_create_module() and sqlite3_create_module_v2() interfaces return SQLITE_MISUSE on any attempt to overload or replace a virtual table module. The destructor is always called in this case, in accordance with historical and current documentation.

Sqlite 3.7.14

Changelog:
  • Drop built-in support for OS/2. If you need to upgrade an OS/2 application to use this or a later version of SQLite, then add an application-defined VFS using the sqlite3_vfs_register() interface. The code removed in this release can serve as a baseline for the application-defined VFS.
  • Ensure that floating point values are preserved exactly when reconstructing a database from the output of the ".dump" command of the command-line shell.
  • Added the sqlite3_close_v2() interface.
  • Updated the command-line shell so that it can be built using SQLITE_OMIT_FLOATING_POINT and SQLITE_OMIT_AUTOINIT.
  • Improvements to the windows makefiles and build processes.
  • Enhancements to PRAGMA integrity_check and PRAGMA quick_check so that they can optionally check just a single attached database instead of all attached databases.
  • Enhancements to WAL mode processing that ensure that at least one valid read-mark is available at all times, so that read-only processes can always read the database.
  • Performance enhancements in the sorter used by ORDER BY and CREATE INDEX.
  • Added the SQLITE_DISABLE_FTS4_DEFERRED compile-time option.
  • Better handling of aggregate queries where the aggregate functions are contained within subqueries.
  • Enhance the query planner so that it will try to use a covering index on queries that make use of or optimization.
  • SQLITE_SOURCE_ID: "2012-09-03 15:42:36 c0d89d4a9752922f9e367362366efde4f1b06f2a"

  • Enhanced support for QNX.
  • Work around an optimizer bug in the MSVC compiler when targeting ARM.
  • Bug fix: Avoid various concurrency problems in shared cache mode.
  • Bug fix: Avoid a deadlock or crash if the backup API, shared cache, and the SQLite Encryption Extension are all used at once.

  • Improved optimization of queries containing aggregate min() or max().
  • Enhance virtual tables so that they can potentially use an index when the WHERE clause contains the IN operator.
  • Allow indices to be used for sorting even if prior terms of the index are constrained by IN operators in the WHERE clause.
  • Enhance the PRAGMA table_info command so that the "pk" column is an increasing integer to show the order of columns in the primary key.
  • Enhance the query optimizer to exploit transitive join constraints.
