| 11:44 | Experimental "PRAGMA secure_delete=FAST" pragma. The intent is to overwrite deleted content with zeros without increasing the amount of disk I/O. (Closed-Leaf check-in: f1682f0faf user: drh tags: fast-secure-delete) | |

| 20:31 | Performance improvements in btreeParseCell() by inlining the varint decoder. (check-in: 172a864d14 user: drh tags: trunk) | |
| 20:08 | Fix corner cases involving corrupt varint values in record headers. (Closed-Leaf check-in: 3189116b42 user: drh tags: btree-opt) | |
| 18:24 | Performance improvements in btreeParseCell() by inlining the varint decoder. (check-in: faab0ed928 user: drh tags: btree-opt) | |
| 17:19 | Add the MemPage.xParseCell method and provide various implementations (variations on the former btreeParseCellPtr()) depending on the page type. (check-in: 41d03d883c user: drh tags: trunk) | |
| 15:07 | Make cellSizePtr() a method on the MemPage object, with alternative implementations depending on the page type. This results is a small performance improvement and size reduction. (check-in: 02f7e9d7d7 user: drh tags: trunk) | |

| 23:48 | Merge in trunk changes to os_unix.c that allow the code to build on unix platforms that lack posix_fallocate(). (check-in: bf5764067a user: drh tags: nextgen-query-plan-exp) | |
| 20:13 | Add the languageid_bits= option to fts. Still some problems to work out. (check-in: d36d7e6833 user: dan tags: fts-languageid-bits) | |
| 18:01 | Add in the cost of doing a table lookup on OR searches. Make test case changes to deal with difference in STAT3 behavior. (check-in: d97898e8e3 user: drh tags: nextgen-query-plan-exp) | |
| 14:49 | Only default HAVE_POSIX_FALLOCATE on for linux, and then only if it is not previously defined. (check-in: 2b2ade9278 user: drh tags: trunk) | |
| 14:28 | Only enable posix_fallocate by default on linux and mac. (check-in: b9b30d4f98 user: drh tags: trunk) | |
| 13:59 | Additional compiler warning fixes. (check-in: 8d2ae8e2f3 user: drh tags: nextgen-query-plan-exp) | |
| 13:32 | Fix a harmless uninitialized variable warning. (check-in: 9d3ef3bd2c user: drh tags: nextgen-query-plan-exp) | |
| 12:34 | Simplify and add invariants to the WhereLoop merging logic inside of whereLoopInsert(). (check-in: 8f27f35f28 user: drh tags: nextgen-query-plan-exp) | |
| 03:27 | Fix compiler warnings. Fix a harmless off-by-one error in the solver. (check-in: 10021941d0 user: drh tags: nextgen-query-plan-exp) | |

| 18:39 | Unset global TCL variables in the func.test script prior to use to avoid conflicts from other scripts. (CVS 5251) (check-in: 9b04e10f6c user: drh tags: trunk) | |
| 18:17 | Move the malloc() failure simulation out of malloc.c and into a separate sqlite3_mem_methods interface. Still some related changes to come. (CVS 5250) (check-in: d22cd2a59f user: danielk1977 tags: trunk) | |
| 17:54 | Documentation and test-script updates. (CVS 5249) (check-in: 68d4f79541 user: drh tags: trunk) | |
| 16:07 | Fix some minor compile problems. (CVS 5248) (check-in: 7d38da3eea user: drh tags: trunk) | |
| 15:44 | Additional test cases for loadable extensions. (CVS 5247) (check-in: 9d73a68c30 user: drh tags: trunk) | |
| 15:06 | Add recent API additions to the loadable extension interface. (CVS 5246) (check-in: 12ba27d94e user: drh tags: trunk) | |
| 13:20 | Check in the missing status.c source file. (CVS 5245) (check-in: 298113d4a7 user: drh tags: trunk) | |
| 08:51 | Shuffle some of the mutex related documentation in sqlite.h.in to match the new sqlite3_mutex_methods based API. (CVS 5244) (check-in: 9cd7f8669a user: danielk1977 tags: trunk) | |
| 02:52 | Add the sqlite3_next_stmt() interface, including test cases. (CVS 5243) (check-in: 565a530896 user: drh tags: trunk) | |
| 01:50 | Fix a bug in the noop-mutex implementation. (CVS 5242) (check-in: eec9a54dc3 user: drh tags: trunk) | |
| 01:03 | Bug fixes: Plug a memory leak introduced by the previous check-in. Get the amalgamation to the point where it will compile. (CVS 5241) (check-in: 005f8eaef5 user: drh tags: trunk) | |
| 00:16 | Add some test logic to the new memory allocation subsystem. (Lots more needed.) The test suite is currently indicating memory leaks, though it is unclear if this is a true code problem or just an instrumentation problem. (CVS 5240) (check-in: cb1f11cd97 user: drh tags: trunk) | |
