|
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) | |
|
2011-03-16
| ||

| 04:45 | Allow multiplex file names to be preceeded by prefix of the form ":multiplex:chunksize:maxchunks:" Still work to be done, though it compiles and prefixes are ignored. (check-in: cfa4a2f7 user: shaneh tags: multiplex-enhancements) | |
| 02:55 | Fix cut-and-paste typo in debugging print statement in winMutexTry(). (check-in: def98fd2 user: shaneh tags: trunk) | |

|
2011-03-12
| ||
| 18:10 | In the "unix-excl" VFS, use the heap for shared memory, since only a single process is able to read or write the database. (Closed-Leaf check-in: a05a6d40 user: drh tags: unix-excl) | |
| 17:22 | Fix some issues with UPDATE changes in the session module. (check-in: 57862efe user: dan tags: sessions) | |

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

| 21:36 | Fix issue with mem5 allocator when min request size is larger thatn 2^30. (check-in: d7dae06f user: shaneh tags: trunk) | |
| 21:02 | Omit unnecessary OP_Next and OP_Prev operators when uniqueness constraints guarantee that the code will only make one pass through the loop. (check-in: f000c9b2 user: drh tags: trunk) | |
| 11:17 | Add a function to the session extension invert a changeset. (check-in: 75d5dff7 user: dan tags: sessions) | |

| 16:39 | Merge the syscall-override changes into trunk. (check-in: 36d79e6f user: drh tags: trunk) | |
| 14:05 | Unix errno integer can vary from one system to the next. So do not depend on specific errno values in test cases. (check-in: ddb747d3 user: drh tags: trunk) | |
| 13:06 | Fix two compiler warnings. No functional code changes. (check-in: c829868a user: drh tags: trunk) | |

|
2011-03-06
| ||
| 21:54 | Another minor simplification brought to light by clang. (check-in: 3bfbf026 user: drh tags: trunk) | |
| 21:28 | Remove dead code identified by the clang static analyzer. (check-in: 01a79d5a 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) | |

|
2011-02-24
| ||
| 21:10 | Fix a typo in a comment. No changes to code. (check-in: af475618 user: drh tags: trunk) | |
|
2011-02-23
| ||
| 22:39 | Reserve a range of bits in the SQLITE_OPEN_xxxx bit vector for future expansion. (check-in: 9b904654 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) | |
|
2011-02-22
| ||
| 03:34 | When a stale schema-cookie is seen, expire only the one statement that encountered the bad cookie, not every statement on the database connection. Ticket [b72787b1a7cea1f] (check-in: 1bca0a7e user: drh tags: trunk) | |

|
2011-02-19
| ||
| 23:18 | An SQLITE_PROTOCOL error counts as a locking error for verification purposes. (check-in: e87d499a user: drh tags: trunk) | |
| 17:02 | Change a testcase() added by the previous checkin into an assert(). (check-in: 6f3dad32 user: drh tags: trunk) | |

|
2011-02-17
| ||
| 15:58 | Remove a no-op code path from sqlite3ExprIsInteger(). Replace it with an assert() that proves it always does nothing. (check-in: 7af66d1b user: drh tags: trunk) | |

|
2011-02-14
| ||
| 03:49 | Skip some tests in capi3e.test when compiled with SQLITE_OMIT_UTF16. (check-in: b04304b9 user: shaneh 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) | |

| 15:25 | Update Makefile.in for fts3_aux changes. (check-in: 38b7cb33 user: shaneh tags: trunk) | |
| 03:04 | Use macros to define the relative costs of search and seek operations when computing costs in the query planner. Current constants seems wrong and need to be fixed, but doing so will alter test results. Need more experimentation to determine accurate relative costs. (check-in: 5f2ec44b user: drh tags: trunk) | |
| 03:03 | Simplifications to the sqlite3_wal_checkpoint_v2() logic. (check-in: 652b8835 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

| 01:57 | Change the weighting of binary searches on tables to 1/10th the cost of a search on an index. Change the assumed reduction in search space from a indexed range constraint from 1/3rd to 1/4th. Do not let the estimated number of rows drop below 1.

|
2011-01-22
| ||
| 00:10 | Add the ability to use indices for constraints of the form "x IS NOT NULL" when sqlite_stat2 is available and most entries for column x are NULL. (check-in: 5d5bddd2 user: drh tags: stat2-enhancement) | |
|
2011-01-21
| ||
| 18:18 | Adjustments to the result row estimator for the IN operator so that it gives the same estimates as the equivalent OR operator. Test cases for the same. (check-in: c82cb9c0 user: drh tags: stat2-enhancement) | |
