|
2011-03-17
| ||
| 19:20 | Change to the session module to use user-defined primary keys instead of rowids when collecting changes. check-in: 6614cfcb user: dan tags: sessions | |
| 16:45 | Update the implementation of ".testctrl" in the command-line shell to use a look-up table rather than a long sequence of if-elses. Shorten source code lines of shell.c to 80 characters or less. check-in: 54bacb95 user: drh tags: trunk | |
| 01:58 | Comment enhancement to better explain the logic in the "x IS NULL" optimization. check-in: 869f8947 user: drh tags: trunk | |
| 01:34 | Enhances to the query planner such that "x IS NULL" constraints take the STAT2 statistics into account, just like "x=VALUE" constraints. check-in: 23531768 user: drh tags: trunk | |

| 04:58 | More tests for SQLITE_OMIT_UNIQUE_ENFORCEMENT and minor change to implementation. check-in: b8699943 user: shaneh tags: trunk | |

| 19:22 | Add start of sessions feature. check-in: 269a81a3 user: dan tags: sessions | |
| 16:39 | Merge the syscall-override changes into trunk. check-in: 36d79e6f user: drh tags: trunk | |

|
2011-03-05

| 21:41 | Simplifications to the overflow-free multiplier. Also remove some commented-out code that was left in that subroutine by mistake on the previous check-in. check-in: 55fc25fd user: drh tags: trunk | |
| 20:59 | Fix all known instances of signed-integer overflow. Within SQL expressions, integer overflow now forces coercion to floating point. The shift operators work with any integer right-hand operand with negative values reversing the direction of the shift. check-in: abf21394 user: drh tags: trunk | |
| 13:54 | Fix an instance of signed arithmetic overflow and an one bit-shift overflow. Mark six other signed arithmetic overflow locations that need fixing. check-in: 04abab71 user: drh tags: trunk | |

| 14:00 | Fix a typo in the robust_flock() macro for systems without EINTR. check-in: af9ba2a6 user: drh tags: trunk | |
| 13:53 | The robust_flock() fix that accidently included some unrelated, though harmless changes. I should follow my own checklist! Closed-Leaf check-in: e701efbd user: drh tags: mistake | |
| 13:33 | Retry selected system calls on unix when they fail with EINTR. check-in: b9d29ea3 user: drh tags: trunk | |

| 17:46 | Prevent a segfault when automatic indices try to use a column with an unknown collating function. Ticket [77aa3b1e6592582e38605d36]. This check-in also removes some stray \r characters unrelated to the problem. check-in: f01030a0 user: drh tags: trunk | |
| 00:08 | Refactor the cost function in the query planner. Give extra cost (thus reduce likelihood of selection) to full table scans. check-in: 878da276 user: drh tags: trunk | |
|
2011-02-09
| ||
| 19:55 | Make sure code *compiles* with each OMIT and ENABLE option. Mostly changes to test modules. check-in: 7cc515ed user: shaneh tags: trunk | |

| 03:03 | Simplifications to the sqlite3_wal_checkpoint_v2() logic. check-in: 652b8835 user: drh tags: trunk | |
|
2011-02-07
| ||
| 23:56 | Cleanup to the OP_Checkpoint opcode. check-in: f611a5a8 user: drh tags: trunk | |

| 15:12 | Change blocking-checkpoint tests so that they run once using "PRAGMA wal_checkpoint" and once using calls to sqlite3_wal_checkpoint_v2(). Also fix edge cases surrounding the output variables set by wal_checkpoint_v2(). check-in: 5a4b6652 user: dan tags: trunk | |
|
2011-02-05

|
2011-01-21
| ||
