2014-09-18
| ||
| 11:15 | Fix an ota bug causing attempts to write to tables with more than 8 columns to fail. (check-in: 7da98ca242 user: dan tags: ota-update) | |
|
2014-09-17
| ||
| 23:37 | Performance improvement and slight size reduction to the comparison operators in the VDBE. (check-in: 14052a7d08 user: drh tags: micro-optimizations) | |
| 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) | |
|
2014-09-16
| ||
| 21:54 | Continuing cleanup of memory register memory allocation handling. (check-in: 2598aedc5d user: drh tags: micro-optimizations) | |
| 20:05 | Make sure registers are cleared properly prior to being used to store the result of an OP_Column operator. (check-in: 78fb8838d8 user: drh tags: micro-optimizations) | |
| 20:02 | Clarify the effects of the pager_ota_mode pragma. Add tests and fixes for the same. (check-in: decaccc37c user: dan tags: ota-update) | |
| 18:22 | Simplification of the OP_Column logic for the case of rows with overflow. (check-in: f73678038d 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) | |
| 13:30 | Changes to sqlite3VdbeRecordUnpack() to make it slightly smaller and faster. (check-in: 8fb90da77c user: drh tags: trunk) | |
| 03:24 | Performance improvement to the sqlite3MemCompare() routine by factoring out sqlite3BlobCompare(). (check-in: 20ed2321b0 user: drh tags: trunk) | |
|
2014-09-15
| ||
| 19:34 | Remove the experimental sqlite3_transaction_save() and restore() APIs. (check-in: 48d201cd8b user: dan tags: ota-update) | |
| 16:57 | Merge latest trunk fixes into this branch. (check-in: 5efafef51d user: dan tags: ota-update) | |
| 16:53 | Fix tool/showwal.c so that it handles WAL files that contain 64KiB pages. (check-in: 4060efb646 user: dan tags: trunk) | |
| 16:50 | Avoid attempting to call the xFetch() method of an sqlite3_io_methods object with a version number less than 3. (check-in: dedaa6fb3d user: dan tags: trunk) | |
| 15:34 | Merge latest trunk changes with this branch. (check-in: 55b8011d5b user: dan tags: ota-update) | |
| 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) | |
| 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) | |
|
2014-09-12
| ||
| 20:30 | Small performance improvement to the dirty list handling in the pager. (check-in: b332a84d51 user: drh tags: trunk) | |
| 17:41 | Simplify the way the column cache is managed around OP_Move instructions. (check-in: 320556233e user: drh tags: trunk) | |
| 04:28 | Fix a problem with parser memory allocation on 32-bit systems. (check-in: 2f69a1fa6a user: drh tags: trunk) | |
|
2014-09-11
| ||
| 23:34 | Fix an issue with sqlite3_bind_text64() with the SQLITE_UTF16 encoding parameter. Remove some unreachable code from the text64() and blob64() implementation. (check-in: 34292b084e 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) | |
|
2014-09-09
| ||
| 20:30 | Change the name of the _texte64() interfaces to just _test64(), without the "e". (Closed-Leaf check-in: 6ab76c5fed user: drh tags: 64-bit-lengths) | |
| 18:41 | Add new interfaces to the loadable extension mechanism. (check-in: 18d80cbc59 user: drh tags: 64-bit-lengths) | |
| 17:27 | Add new APIs that take 64-bit length parameters: sqlite3_malloc64(), sqlite3_realloc64(), sqlite3_bind_blob64(), sqlite3_bind_texte64(), sqlite3_result_blob64(), and sqlite3_result_texte64(). Internal memory allocation routines also now use 64-bit unsigned length parameters for safety. Also add the sqlite3_msize() interface. Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid a integer overflow problem. (check-in: 94954850cf user: drh tags: 64-bit-lengths) | |
