|
2013-03-28
| ||
| 11:40 | Adjustment to an extreme corner case in the sqlite3Atoi64() routine. (check-in: 39534b4b user: drh tags: trunk) | |
| 01:19 | Merge the changes for the 3.7.16.1 release candidate into the sessions branch. (check-in: ee35a897 user: drh tags: sessions) | |
|
2013-03-27
| ||
| 21:12 | • Fixed ticket [38b1ae01]: Assertion fault on valid FTS4 query plus 5 other changes (artifact: 48cf60d5 user: drh) | |
| 21:11 | • Fixed ticket [6bfb98df]: False report of database corruption on an INSERT plus 5 other changes (artifact: f41e9efa user: drh) | |
| 20:41 | Fix harmless compiler warnings coming from MSVC64 in test code. No changes to the core. (check-in: 274d2a22 user: drh tags: trunk) | |
| 19:46 | Increment the version number to 3.7.16.1. (check-in: 7e32eb7b user: drh tags: trunk) | |
| 17:20 | • Fixed ticket [a179fe74]: Incorrect output order on a join with an ORDER BY plus 3 other changes (artifact: 16d5b731 user: drh) | |
| 17:20 | In order to optimize out the ORDER BY clause, outer loops must generate values for ORDER BY terms that are unique or else the inner loops must generate no more than a single row. Fix for ticket [a179fe7465]. (check-in: 2936f746 user: drh tags: trunk) | |
| 16:42 | Restore additional ORDER BY optimizations that where broken by the recent ORDER BY fix. (Closed-Leaf check-in: c77ee6e2 user: drh tags: orderby-fix) | |
| 16:05 | Improved optimization of ORDER BY. (check-in: 97e5c70f user: drh tags: orderby-fix) | |
| 15:04 | A fix and test-case for the ORDER BY problem identified by ticket [a179fe7465]. This change causes sorting to occur in some cases where it is not strictly necessary. Further work is needed to avoid those extra sorts. (check-in: 488089e6 user: drh tags: orderby-fix) | |
| 14:28 | • Ticket [a179fe74] Incorrect output order on a join with an ORDER BY status still Open with 3 other changes (artifact: 82a0e96f user: drh) ... 1 similar event omitted. | |

|
2013-03-26
| ||
| 18:48 | Fix a comment in os_unix.c. No code changes. (check-in: 72813b8e user: drh tags: experimental-mmap) | |
| 14:36 | Change the name of the Pager.pFree field to Pager.pMmapFreelist. (check-in: 611bd824 user: drh tags: experimental-mmap) | |
| 01:07 | Previous check-in accidently left mmap turned off by default. This checkin fixes that. Unfortunately, shared.test is now segfaulting. All other veryquick tests appear to work, however. (check-in: a850c731 user: drh tags: experimental-mmap) | |
|
2013-03-25
| ||
| 23:09 | Memory-mapped I/O is now on by default. The "PRAGMA mmap_limit(N)" can be used to issue a hint to the VFS to limit mmap space to N bytes. The VFS is free to ignore that hint if desired. However, if "PRAGMA mmap_limit(0)" is used, xFetch is never called. (check-in: 1b37c4ef user: drh tags: experimental-mmap) | |
| 20:50 | Add munmap and mremap to the set of os interfaces that can be overloaded in os_unix.c. (check-in: 8776047b user: drh tags: experimental-mmap) | |

|
2013-03-24

|
2013-03-22

| 12:04 | Fix text-to-numeric type casting so that it works correctly on UTF16 strings that contain characters where the LSB is numeric but the MSB is non-zero. Ticket [689137afb6da41] (check-in: 5b22053f user: drh tags: trunk) | |
| 11:08 | • New ticket [689137af] Casting UTF16 to numeric types fails. (artifact: 4c66baf3 user: drh) | |

|
2013-03-18
| ||
| 17:18 | Clarifications to the documentation for the sqlite3_aggregate_context() API. Also, shorten an over-length source line in sqlite.h.in. (check-in: 4fe2db1d user: drh tags: trunk) | |
| 16:24 | Adjust the MSVC makefile so that it correctly handles the sessions extension being included in the amalgamation. Import the test case changes that appeared in 3.7.16 final. (check-in: 9bac09a9 user: drh tags: sessions) | |
| 11:39 | Version 3.7.16 (check-in: 66d5f2b7 user: drh tags: trunk, release, version-3.7.16) | |

| 00:13 | Fix the ORDER BY with IN constraint logic so that it works with all combinations of DESC on the ORDER BY clause, on the RHS of the IN operator, and in the index used by ORDER BY and IN. Fix for ticket [4dd95f6943fbd18]. (check-in: 839aa91f user: drh tags: trunk) | |
|
2013-03-12
| ||
| 23:58 | Add a single new test case to the ORDER BY with IN logic verify that if the RHS of the IN is a descending index that it still works. Add testcase() macros to the ORDER BY with IN logic to help verify that corner cases are tested. (Closed-Leaf check-in: 7e7356f1 user: drh tags: desc-orderby-fix-1) | |
| 22:13 | Fix a test case that had an ambiguous result. (check-in: 38c6bddf user: drh tags: desc-orderby-fix-1) | |
