* Added the sqlite3_wal_checkpoint_v2() interface and enhanced the wal_checkpoint pragma to support blocking checkpoints. * Improvements to the query planner so that it makes better estimates of plan costs and hence does a better job of choosing the right plan, especially when SQLITE_ENABLE_STAT2 is used. * Fix a bug which prevented deferred foreign key constraints from being enforced when sqlite3_finalize() was not called by one statement with a failed foreign key constraint prior to another statement with foreign key constraints running. * Integer arithmetic operations that would have resulted in overflow are now performed using floating-point instead. * Increased the version number on the VFS object to 3 and added new methods xSetSysCall, xGetSysCall, and xNextSysCall used for doing full-coverage testing. * Increase the maximum value of SQLITE_MAX_ATTACHED from 30 to 62 (though the default value remains at 10). * Enhancements to FTS4: - Added the fts4aux table - Added support for compressed FTS4 content * Enhance the ANALYZE command to support the name of an index as its argument, in order to analyze just that one index. * Added the "unix-excl" built-in VFS on unix and unix-like platforms. |
