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) | |
| 13:52 | Remove an assert() that was made redundant by the previous checkin. (check-in: 21db7191 user: drh tags: trunk) | |
| 13:33 | Add an ALWAYS() around a always-true test in where.c. (check-in: 8123283e user: drh tags: trunk) | |
|
2011-02-16
| ||
| 23:32 | Fix harmless compiler warnings in the query planner. (check-in: 31fc4ba6 user: drh tags: trunk) | |
| 01:23 | Add "do_not_use_codec" logic to some of the TCL based test cases that read/write directly to the DB. (check-in: edd27669 user: shaneh 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) | |
|
2011-02-11
| ||
| 22:54 | Add a NEVER() around a test that is believed to always be false. (check-in: f7e2ea33 user: drh tags: trunk) | |
| 20:52 | Skip flattening if subquery has LIMIT and outer query is DISTINCT. Fix for ticket [752e1646fc]. (check-in: 55973999 user: shaneh tags: trunk) | |
| 06:59 | Fix a bug in the new WHERE-clause processing that tries to use an index to resolve IS NOT NULL constraints when SQLITE_ENABLE_STAT2 is defined. The bug could cause memory overruns and segfaults. The bug was new to the code and has not appeared in an official release. Found during structural testing. (check-in: a5c36b9f user: drh tags: trunk) | |
| 03:56 | Allow an index paired with an IS NULL constraint to be used for sorting under the condition that the index be treated as a non-unique index. (check-in: d78949fc user: drh tags: trunk) | |
| 02:43 | Disable unused NULL tests when SQLITE_ENABLE_STAT2 is not in use. (check-in: 5ecd1178 user: drh tags: trunk) | |
|
2011-02-10
| ||
| 21:08 | Add .testctrl option to CLI. (check-in: f85afa0e user: shaneh tags: trunk) | |
| 18:56 | Split the documentation for sqlite3_wal_checkpoint_v2() and its constants onto separate pages. No changes to code. (check-in: 0ef8ffd1 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) | |
| 18:19 | Do not report corruption if the the db size header field is greater than the file size on disk unless the two change-counter header fields are identical. Fix for ticket [89b8c9ac54]. (check-in: 00c4596f user: dan 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) | |
|
2011-02-07
| ||
| 23:56 | Cleanup to the OP_Checkpoint opcode. (check-in: f611a5a8 user: drh tags: trunk) | |
| 16:24 | Fix some test cases in walfault.test. Extend one test case to restore code coverage. Add wal5.test to the "coverage-wal" permutation. (check-in: f83b07ac user: dan 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
| ||
| 15:47 | Ensure fts4aux can handle a table name in single or double quotes as a constructor argument. (check-in: 929d62e4 user: dan tags: trunk) | |
| 14:37 | Add test cases for fts4aux. Fix a bug affecting fts3 tables with multiple columns. (check-in: dc511e60 user: dan tags: trunk) | |
|
2011-02-04
| ||
| 18:56 | Change fts4aux to (additionally) report on term frequency in individual columns of an fts table. (check-in: 3996f92a user: dan tags: trunk) | |
| 14:28 | Significant changes have occurred since the 3.7.5 release so go ahead and increase the version number to 3.7.6. (check-in: 999c915a user: drh tags: trunk) | |
| 06:36 | Merge the stat2 query planner enhancements into the trunk. (check-in: 499edcbc user: drh tags: trunk) | |
|
2011-01-28
| ||
| 03:13 | Reactivate the analyze5.test script. (Closed-Leaf check-in: a2a9f640 user: drh tags: stat2-enhancement) | |
| 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. (check-in: 4847c6cb user: drh tags: stat2-enhancement) | |
|
2011-01-24
| ||
| 17:46 | Restructuring and generalizing analyze5.test. The whole script is currently disabled and will need to be reenabled prior to merging with trunk. (check-in: 31fcc706 user: drh tags: stat2-enhancement) | |
| 15:11 | Change the cost estimator in the query planner to take into account the logN rowid lookup cost when going from an index to a table. (check-in: b442525b user: drh tags: stat2-enhancement) | |
|
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) | |
| 16:27 | Make use of histogram data to make better estimates for the number of rows that will be returned from "x IN (v1,v2,v3,...)" constraints. (check-in: fd3977a2 user: drh tags: stat2-enhancement) | |
| 14:37 | Add the ability to use indices when a range contraint is bounded on the lower end by NULL. (check-in: f73a167b user: drh tags: stat2-enhancement) | |
