| 01:02 | Identify specific FuncDef objects for window functions using the pointer to the function name (FuncDef.zName) rather than the pointer to the xStep method. This allows xStep method pointer to be replaced with a single noopStepFunc() procedure, and thus save having lots of different no-op step functions. (check-in: 410e13b0 user: drh tags: trunk) | |

| 22:30 | Add the --icc, --gcc7, and --orm options to the speed-check.sh test script. (check-in: 70dae08a user: drh tags: trunk) | |
| 20:46 | Support read-only MVCC transactions in server-mode. Started using "BEGIN READONLY". (check-in: 5a043aa8 user: dan tags: server-process-edition) | |

| 01:01 | Fix the covering index OR optimization (check-in [fcbd6abd]) so that it works with SQLITE_MAX_ATTACHED>30. Broken by a bad cherry-pick merge. (check-in: d227de8a user: drh tags: branch-3.8.9) | |

| 21:14 | Initial work on a Win32 VFS with NOP locking. (Closed-Leaf check-in: 549abe3f user: mistachkin tags: win32nolock) | |
| 19:54 | Another attempt to fix error handling in Lemon. This change is a no-op for SQLite's usage. (check-in: e1d8ef31 user: drh tags: trunk) | |
| 02:14 | In the sqldiff program, make sure the first argument to the db_prepare() utility function is always a valid format string. (check-in: 8bb8d886 user: drh tags: trunk) | |

| 17:59 | Fix two problems that could cause fts3 auxiliary functions to occasionally misbehave if used with match expressions that contain both OR and NEAR. (check-in: 372c1db2 user: dan tags: trunk) | |
| 16:22 | Enhance the pcache1 page cache so that it tries to allocate a block of SQLITE_DEFAULT_PCACHE_INITSZ pages from malloc() on startup, and uses those preallocated pages when possible rather than going to malloc() for each individual page. About a 5% performance increase for some workloads. (check-in: 5348ffc3 user: drh tags: trunk) | |
| 14:13 | Comment fix. No changes to code. (Closed-Leaf check-in: c1e2ed0e user: drh tags: pcache-bulk-local) | |

| 12:25 | Early detection of file corruption in a debugging routine, before the invalid data can cause problems. (check-in: b27a47fe user: drh tags: trunk) | |
| 01:22 | Avoid left-shifting bits into the sign of a signed integer, as such behavior is technically undefined. (check-in: 9417b402 user: drh tags: pcache-bulk-local) | |

| 19:20 | • Edit [bcdddba4f011cf00|bcdddba4]: Edit check-in comment. Timestamp 2010-07-08 19:19:51. (artifact: 2e0de1a9 user: drh) | |
| 19:19 | Replace code that became unreachable due to the journal_mode simplification with an assert(). (check-in: bcdddba4 user: drh tags: trunk) | |
| 18:32 | Fix test case numbering in backup_malloc.test and issue when running under Windows. (check-in: aef26438 user: shaneh tags: trunk) | |
| 17:40 | Change the journal_mode pragma to remove the "default journal mode" concept. The journal_mode pragma only effects currently attached databases and does not change the behavior of future attachments. (check-in: e396184c user: drh tags: trunk) | |
| 17:22 | • Edit [8a5811ea80e8415f|8a5811ea]: Change branch background color to "#c0ffc0". Timestamp 2010-07-08 16:30:44. (artifact: 9bbd9dd8 user: drh) | |
| 16:50 | Merged experimental crashsql() into trunk. (check-in: 01b575ff user: shaneh tags: trunk) | |
| 16:30 | Changes to get crashsql() working on Windows. (Closed-Leaf check-in: 8a5811ea user: shaneh tags: experimental) | |
| 16:22 | Fix warning in test fixture code. (check-in: 0bfcf3bc user: shaneh tags: trunk) | |
| 16:22 | Fix test case number issue in walcrash.test. (check-in: 6a46e641 user: shaneh tags: trunk) | |
| 14:59 | Fix to lock5.test so that it runs with the inmemory_journal permutation on osx. (check-in: 948bb545 user: dan tags: trunk) | |
| 13:33 | Fixed a few tests in pagerfault.test so they work correctly on Windows. (check-in: ffbdd954 user: shaneh tags: trunk) | |
| 09:44 | Changes to test scripts so that the "inmemory_journal" permutation works with [ef126e775a]. (check-in: f553c8ed user: dan tags: trunk) | |
| 06:22 | Add tests to walmode.test. (check-in: 5aa2bdb5 user: dan tags: trunk) | |
| 03:13 | Changes to os_win.c to have it simulate IO errors like os_unix.c. (check-in: 0d53da94 user: shaneh tags: trunk) | |

| 18:25 | Allow the IN operator to take a list of arbitrary expressions on its right-hand side. The expressions no longer need to be constant. The current implementation seems to work but needs more testing and optimization. (CVS 2542) (check-in: ba56478d user: drh tags: trunk) | |
| 17:13 | Change the name of the OpenTemp opcode to OpenVirtual which is more descriptive of what it does. (CVS 2541) (check-in: 3bb9ce5f user: drh tags: trunk) | |
| 14:14 | Add the EP_OptOnly flag on expressions for WHERE clause terms that are added by the optimizer but should not be coded. (CVS 2540) (check-in: f4a66ed0 user: drh tags: trunk) | |
| 13:53 | Add the SQLITE_CASE_SENSITIVE_LIKE compile-time option. (CVS 2539) (check-in: b72bff81 user: drh tags: trunk) | |
| 13:08 | Replace OP_List with OP_Fifo. This is the first step toward allowing recursive delete triggers and later foreign keys with cascading deletes. (CVS 2538) (check-in: 94c120bb user: drh tags: trunk) | |
| 12:13 | Add infrastructure for the ANALYZE command. Does not yet actually do anything. (CVS 2537) (check-in: 05b6ac9a user: drh tags: trunk) | |
