| 19:05 | Fix an unintialized variable problem in sqlite3ota.c. (check-in: 0126860751 user: dan tags: ota-update) | |
| 16:41 | In the Mem object, stop requiring that Mem.xDel be NULL when the MEM_Dyn bit is clear. Also reduce the amount of initialization of Mem objects. All for a small size reduction and performance increase. (check-in: fdddb477c8 user: drh tags: micro-optimizations) | |
| 15:20 | Add tests and fixes for "PRAGMA ota_mode". (check-in: 39df35c4ac user: dan tags: ota-update) | |
| 14:52 | Improved interface to the Mem object handling. Small size reduction and performance increase. (check-in: 4e43784432 user: drh tags: micro-optimizations) | |

| 14:55 | Remove an unused parameter from sqlite3VdbeIdxRowid(). This is cosmetic only as the C-compiler optimizers were already omitting this parameter on amalgamation builds. (check-in: a10a6bba49 user: drh tags: micro-optimizations) | |
| 14:37 | Reduce the number of arguments to RecordCompare functions from 4 to 3, resulting in a small performance increase. (check-in: 8239c35aed user: drh tags: micro-optimizations) | |
| 14:16 | Reorder the elements of the Mem object for a small size reduction and performance improvement. Moved into a branch because MSVC is unable to handle named structure initializer on nullMem. (check-in: 0be3019ed7 user: drh tags: micro-optimizations) | |

| 14:59 | Remove the EXPENSIVE_ASSERTS in pcache.c having to do with the pSynced field of the Pcache object, as they are incorrect, as revealed by recent pcache enhancements. (check-in: 69a6456077 user: drh tags: trunk) | |

| 14:46 | Do not flatten aggregate subqueries that contain min() or max() functions so that if the min()/max() are discarded by the outer query, they still function and cause non-aggregate expression to be evaluated on the minimal or maximal row. (check-in: 0bdf1a086b user: drh tags: trunk) | |
| 12:18 | Have the sqlite3_index_writer() VMs check that the final values of records inserted into indexes on rowid tables are integers. (check-in: cca376bff3 user: dan tags: ota-update) | |
| 11:14 | Adjust comments to show that subquery flattening restriction (10) was removed from the code back in 2005. This is a comment change only. (check-in: 4ff0eb96bc user: drh tags: trunk) | |

| 18:44 | Add new APIs that take 64-bit length parameters: sqlite3_malloc64(), sqlite3_realloc64(), sqlite3_bind_blob64(), sqlite3_bind_text64(), sqlite3_result_blob64(), and sqlite3_result_text64(). Add the sqlite3_msize() interface. Internal memory allocation routines now use 64-bit unsigned length parameters for safety. Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid a integer overflow problem. (check-in: 7e4978c003 user: drh tags: trunk) | |
| 17:27 | Add the SQLITE_USER_AUTHENTICATION extension to the trunk. This extension is disabled by default. Special compilation procedures are need to enable it. (check-in: 65884d4f81 user: drh tags: trunk) | |
| 17:14 | Clean up some #includes in the extension API implementation. (Closed-Leaf check-in: b149ef5c63 user: drh tags: user-auth) | |

| 14:01 | Move user authentication blocking from sqlite3_prepare() over to the table lock generator, thus allowing SQL statements (like "PRAGMA locking_mode") that do not touch database content to run prior to authentication. (check-in: 70121e7cf8 user: drh tags: user-auth) | |
| 13:44 | Add support for the extra parameter on the sqlite3_set_authorizer() callback and support for failing an ATTACH with an authentication-required database using bad credentials. The extension is now feature complete, but much testing and bug-fixing remains. (check-in: 596e728b0e user: drh tags: user-auth) | |

Internal memory allocation routines also now use 64-bit unsigned length parameters for safety. Also add the sqlite3_msize() interface.

| 03:16 | Add the sqlite3_memdebug_title_count global variable, used during debugging to count the number of invocations of test_memdebug_settitle. By examining this variable in the debugger after a segfault, one can then set a breakpoint on test_memdebug_settitle that will fire just before the problem.

| 22:46 | When running ANALYZE, it is not necessary to check the right-most key column for changes since that column will always change if none of the previous columns have. (check-in: 48f40861db user: drh tags: trunk) | |
| 20:02 | Add the OP_ReopenIdx opcode that works like OP_OpenRead except that it becomes a no-op if the cursor is already open on the same index. Update the OR-optimization logic to make use of OP_ReopenIdx in order to avoid unnecessary cursor open requests sent to the B-Tree layer. (check-in: 77f412caf0 user: drh tags: trunk) | |
| 19:14 | The optimization of check-in [b67a6e33f2] does not work (it generates incorrect VDBE code) if an OR term is AND-ed with a constant expression. So back that optimization out and add a test case to make sure it does not get added back in. (check-in: eed754fe93 user: drh tags: trunk) | |
