2007 April 25 (3.3.17) * When the "write_version" value of the database header is larger than what the library understands, make the database read-only instead of unreadable. * Other minor bug fixes 2007 April 18 (3.3.16) * Fix a bug that caused VACUUM to fail if NULLs appeared in a UNIQUE column. * Reinstate performance improvements that were added in 3.3.14 but regressed in 3.3.15. * Fix problems with the handling of ORDER BY expressions on compound SELECT statements in subqueries. * Fix a potential segfault when destroying locks on WinCE in a multi-threaded environment. * Documentation updates. 2007 April 9 (3.3.15) * Fix a bug introduced in 3.3.14 that caused a rollback of CREATE TEMP TABLE to leave the database connection wedged. * Fix a bug that caused an extra NULL row to be returned when a descending query was interrupted by a change to the database. * The FOR EACH STATEMENT clause on a trigger now causes a syntax error. It used to be silently ignored. * Fix an obscure and relatively harmless problem that might have caused a resource leak following an I/O error. * Many improvements to the test suite. Test coverage now exceeded 98% 2007 April 2 (3.3.14) * Fix a bug in 3.3.13 that could cause a segfault when the IN operator is used one one term of a two-column index and the right-hand side of the IN operator contains a NULL. * Added a new OS interface method for determining the sector size of underlying media: sqlite3OsSectorSize(). * A new algorithm for statements of the form INSERT INTO table1 SELECT * FROM table2 is faster and reduces fragmentation. VACUUM uses statements of this form and thus runs faster and defragments better. * Performance enhancements through reductions in disk I/O: * Do not read the last page of an overflow chain when deleting the row - just add that page to the freelist. * Do not store pages being deleted in the rollback journal. * Do not read in the (meaningless) content of pages extracted from the freelist. * Do not flush the page cache (and thus avoiding a cache refill) unless another process changes the underlying database file. * Truncate rather than delete the rollback journal when committing a transaction in exclusive access mode, or when committing the TEMP database. * Added support for exclusive access mode using "PRAGMA locking_mode=EXCLUSIVE" * Use heap space instead of stack space for large buffers in the pager - useful on embedded platforms with stack-space limitations. * Add a makefile target "sqlite3.c" that builds an amalgamation containing the core SQLite library C code in a single file. * Get the library working correctly when compiled with GCC option "-fstrict-aliasing". * Removed the vestigal SQLITE_PROTOCOL error. * Improvements to test coverage, other minor bugs fixed, memory leaks plugged, code refactored and/or recommented in places for easier reading. |
