| 20:38 | Add another test case to altertab.test. (check-in: 828e8849 user: dan tags: alter-table-rename-column) | |
| 20:23 | Fix a problem with renaming a column in a table that has a temp trigger that references another attached database. (check-in: 336b8a09 user: dan tags: alter-table-rename-column) | |
| 20:02 | Fixes for harmless compiler warnings. (check-in: 41b8f38b user: drh tags: alter-table-rename-column) | |
| 16:55 | Fix some harmless compiler warnings and improve defenses against OOM errors. (check-in: 2e2cf992 user: drh tags: alter-table-rename-column) | |
| 16:13 | Merge alter-table-rename-table back into this branch. (check-in: ad704a7c user: dan tags: alter-table-rename-column) | |
| 16:05 | Have "ALTER TABLE ADD COLUMN" reload the entire db schema, as "RENAME COLUMN" and "RENAME TABLE" do. (Closed-Leaf check-in: 8d89ddc1 user: dan tags: alter-table-rename-table) | |
| 15:55 | Merge fixes from the alter-table-rename-column branch that occurred after this branch separated from that one. (check-in: 22e785aa user: drh tags: alter-table-rename-table) | |
| 15:49 | Merge fixes and enhancements from trunk. (check-in: 589186c0 user: drh tags: alter-table-rename-table) | |

| 14:50 | Add the new sqlite3PagerUnrefPageOne() pager method to deal with the special case of unreferencing page1. (check-in: b2e2100c user: drh tags: trunk) | |
| 12:57 | Remove an obsolete optimization in pcache that due to more recent changes was recently making the code a little slower. (check-in: c4e7e175 user: drh tags: trunk) | |
| 12:18 | Small size and performance improvement in pcacheManageDirtyList() by not zeroing the PgHdr.pDirtyNext and PgHdr.pDirtyPrev pointers for PgHdr objects that are not on the dirty list. (check-in: 919863b1 user: drh tags: trunk) | |

| 14:03 | Have "sqldiff --rbu" ignore rows with NULL values in primary key fields. RBU can't handle such rows and the documentation already says sqldiff ignores them. Because the code now uses "=" instead of "IS" to filter on primary key columns, diffs on virtual tables are faster now too. (check-in: f4ba894a user: dan tags: trunk) | |
| 09:35 | If SQLITE_ENABLE_ZIPVFS is defined, journal_mode=off is configured and a savepoint or statement rollback is attempted, move the pager into the error state to prevent the transaction from being committed. This makes it safe to use journal_mode=off with zipvfs under some conditions. (check-in: 38d31e18 user: dan tags: trunk) | |

| 23:51 | Very minor optimizations in the unix VFS. (check-in: 6db3ff45 user: drh tags: trunk) | |
| 22:29 | Performance improvement in sqlite3VarintLen(). (check-in: adf9fefb user: drh tags: trunk) | |
| 20:09 | Small size reduction and performance increase in sqlite3DbMallocSize(). (check-in: 8a80967f user: drh tags: trunk) | |
| 19:51 | Reduce the number of calls to sqlite3BeginBenignMalloc(). (check-in: 0bee6583 user: drh tags: trunk) | |
| 18:52 | Merge recent enhancements from trunk. (check-in: cb772366 user: drh tags: sessions) | |

| 18:01 | Merge the latest trunk enhancements. (check-in: 3dea0474 user: drh tags: begin-concurrent) | |
| 17:53 | • Edit [8079421604dbd40d|80794216]: Move to branch begin-concurrent. (artifact: 222b70f1 user: drh) | |
| 17:48 | Fixes so that it builds without warnings both with and without SQLITE_ENABLE_CONCURRENT. (check-in: 5ed2a445 user: drh tags: begin-concurrent) | |
| 16:48 | • Edit [351bc22fa9b5a2e5|351bc22f]: Edit check-in comment. (artifact: b494f382 user: drh) | |

| 19:29 | Identify additional requirements in the sqlite3_vfs object documentation. (check-in: 47064453 user: drh tags: trunk) | |
| 18:00 | Add tests to quota.test. (check-in: ec9af6eb user: dan tags: trunk) | |
| 16:19 | Call quota callback destructors from within sqlite3_quota_shutdown(). (check-in: fb80c6f3 user: dan tags: trunk) | |
| 15:26 | Boundary value fix to the descriptive comment at the top of test_quota.c. (check-in: 7f6072f0 user: drh tags: trunk) | |
| 15:22 | Merge the test_quota.c module into the trunk. (check-in: 2e1a0202 user: drh tags: trunk) | |
| 15:11 | Fix the TCL interface to test_quota.c so that it works with empty callback scripts. (Closed-Leaf check-in: 19e95f63 user: drh tags: experimental) | |
| 14:58 | Variable name and comment changes to test_quota.c for clearer presentation. (check-in: 38ed1992 user: drh tags: experimental) | |
| 14:45 | Make all private routines in test_quota.c begin with "quota". Fix a test_quota.c segfault when setting a zero-quota. (check-in: c0d0fc3a user: drh tags: experimental) | |
| 14:35 | Add the sqlite3_quota_dump test command. Add a destructor argument on the sqlite3_quota_set() interface. (check-in: 7a624b5a user: drh tags: experimental) | |
| 13:09 | Clean up comments in the test_quota.c source file. (check-in: c1eec7db user: drh tags: experimental) | |
| 12:50 | Update the quota shim so that when the same file is opened multiple times, its size only counts against the quota once. (check-in: f5d26380 user: drh tags: experimental) | |
| 11:50 | • Edit [383eb87bbf560b20|383eb87b]: Change branch background color to "#c0ffc0". Timestamp 2010-09-01 11:40:05. (artifact: 03fb00e6 user: drh) | |
| 11:50 | Add an assert() with an evidence mark to show that automatically generated rowids are positive. (check-in: 740adca3 user: drh tags: trunk) | |

| 17:47 | Fix over-aggressive optimization of ORDER BY as reported on the mailing list. (CVS 2655) (check-in: efbb4bc8 user: drh tags: trunk) | |
| 12:16 | All regression tests now pass with the new bounded-memory sort code. There is still lots of opportunity for optimization, however. (CVS 2654) (check-in: 81259a01 user: drh tags: trunk) | |
| 03:07 | Sorting is now done using a sorting index rather than loading the entire result set into memory and doing a merge sort. The old merge sort technique was a carry-over from SQLite version 1. The new method uses a bounded amount of memory and scales to much larger result sets. There are still errors: some 39 regression tests fail. (CVS 2653) (check-in: 09db0a24 user: drh tags: trunk) | |
