* 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. |
