| ||
| 22:20 | Improve memory allocation error handling on WinCE. (check-in: cdbca259da user: drh tags: trunk) | |
| 22:09 | A bug report coming from from Firefox (https://bugzilla.mozilla.org/show_bug.cgi?id=840377) describes an infinite recursion. We are unable to reproduce the problem. Nevertheless, this check-in should prevent the problem from ever occurring again. (check-in: b7222a2bd0 user: drh tags: trunk) | |
| 09:46 | Improve memory allocation error handling on WinCE. (Closed-Leaf check-in: 09dfc0c915 user: mistachkin tags: wince) | |
|
2013-02-11
| ||
| 13:47 | Add extended error codes for all SQLITE_CONSTRAINT errors. (check-in: 939d828274 user: drh tags: trunk) | |
|
2013-02-09
| ||
| 15:37 | Rename SQLITE_CONSTRAINT_RAISE to SQLITE_CONSTRAINT_TRIGGER. Put the extended constraint error codes in alphabetical order. Add many test cases for the extended constraint error codes. (Closed-Leaf check-in: 3f67437536 user: drh tags: constraint-error-codes) | |
| 13:58 | Add extended error codes for constraint errors. (check-in: 5461104668 user: drh tags: constraint-error-codes) | |
|
2013-02-08
| ||
| 23:18 | Fix a potential NULL-pointer dereference following an OOM error in the query planner logic for virtual tables with OR-connected terms. (Closed-Leaf check-in: 71b6c26053 user: drh tags: IN-with-ORDERBY) | |
| 20:39 | Make sure the virtual tables that take advantage of IN operators sort the RHS of the IN operator in the correct order according to the ORDER BY clause. (check-in: b016b7546d user: drh tags: IN-with-ORDERBY) | |
| 18:48 | Loop through the elements on the RHS of an IN operator in reverse order when the ORDER BY clauses specifies DESC. (check-in: f78395c889 user: drh tags: IN-with-ORDERBY) | |
| 16:04 | Allow the "a=?1 OR a=?2" to "a IN (?1,?2)" transformation to work on virtual tables again. This was formerly restricted because virtual tables could not optimize IN terms. (See check-in [fad88e71cf195e].) But IN terms are now used by virtual tables (as of check-in [3d65c70343]) so the restriction can now be removed. (check-in: a917c1f092 user: drh tags: IN-with-ORDERBY) | |
|
2013-02-07
| ||
| 21:15 | Allow an index to be used for sorting even if prior terms of the index are constrained by IN operators. (check-in: 98bf668ab1 user: drh tags: IN-with-ORDERBY) | |

|
2013-01-30
| ||
| 01:46 | Remove some debugging logic accidently left in the limit.test module. (check-in: 7d346250e8 user: drh tags: trunk) | |
|
2013-01-29
| ||
| 23:55 | Fix LIMIT and OFFSET so that they work and do not leak memory even on complex queries involving deeply nested views of UNION ALL compounds. Ticket [db4d96798da8]. Secondary to ticket [d58ccbb3f1b7]. (check-in: 497ee36cb8 user: drh tags: trunk) | |
| 19:14 | New debugging pragmas: PRAGMA vdbe_debug=ON is short-hand for the sql_trace, vdbe_listing, and vdbe_trace pragmas. PRAGMA vdbe_debug enables tracing of sqlite3VdbeAddOp() calls. None of this is active unless compiled with SQLITE_DEBUG. (check-in: ae565ff3e0 user: drh tags: trunk) | |
|
2013-01-28
| ||
| 22:52 | Fix an issue with the SQLITE_TESTCTRL_EXPLAIN_STMT and compound queries with multiple terms. (check-in: a6499c2521 user: drh tags: trunk) | |
| 19:00 | Issue an error message and quit (rather than overflowing a reference counter) if the number of references to a table exceeds the maximum due to nested UNION views. Fix for ticket [d58ccbb3f1]. (check-in: c2462a95ed user: drh tags: trunk) | |
| 18:18 | Cause the command-line shell to issue an error message if you give something that does not look like a boolean value to a dot-command that wants a boolean argument. (check-in: b4d94947fc user: drh tags: trunk) | |
|
2013-01-26
| ||
| 19:31 | Add a single test case to fts4unicode.test to verify that title-case maps to lower case. (check-in: 955a9459da user: drh tags: trunk) | |
| 19:26 | Add a single test case to fts4unicode.test to verify that title-case maps to lower case. (Leaf check-in: 46f7c9301e user: drh tags: branch-3.7.15) | |
|
2013-01-25
| ||
| 19:11 | Fix the test_spellfix.c extension so that it can be made loadable at run-time. Add spellfix to the shell when building using the build-shell.sh script. (check-in: 7813b17d8b user: drh tags: trunk) | |
| 18:33 | Enhance the command-line shell so that adding a non-zero numeric argument to the ".exit" command causes an immediate exit without cleaning up. This can be used (for example) to cause journal files to be left behind. (check-in: 8ba951d1b7 user: drh tags: trunk) | |
| 15:59 | Add btree-page decoding logic to showwal.c. Commands of the form: "showwal $FILE 123bmc" show the content of the btree page in frame 123. "b" means decode the btree. "c" means show cell content. "m" means give a map of the btree page. (check-in: 93b159da5d user: drh tags: trunk) | |
| 15:31 | Further improvements to showwal.c: Reset the checksum after each frame so that only individual checksum failures are shown. And only show failures, not correct checksums. (check-in: 4e2bf57549 user: drh tags: trunk) | |
| 15:09 | Enhance the "showwal" utility program to show checksum failures on frames. (check-in: a7f6d19816 user: drh tags: trunk) | |
| 02:10 | Enhancements to the query planner to exploit transitive relationships in the WHERE clause, and other minor changes to bring the sessions branch into alignment with the trunk. (check-in: 82d3d1ae82 user: drh tags: sessions) | |
|
2013-01-23
| ||
| 18:53 | Improved parsing of the arguments to the ".backup" command in the command-line shell. (check-in: f1127e87b9 user: drh tags: trunk) | |
| 18:44 | Fix a double-free() call that can occur when SQLITE_ENABLE_TREE_EXPLAIN is defined. (check-in: 5bfb5967d7 user: drh tags: trunk) | |
|
2013-01-20
| ||
| 00:18 | Fix a typo in a comment in the test_regexp.c test file. (check-in: 68346af70b user: drh tags: trunk) | |
|
2013-01-18
| ||
| 03:35 | The \xXX escape in the test_regexp.c must be followed by exactly two hex digits. (check-in: 82957495aa user: drh tags: trunk) | |
|
2013-01-17
| ||
| 17:20 | Enhance the query planner to exploit transitivity of join constraints. (check-in: 38852f158a user: drh tags: trunk) | |
| 17:05 | Improved error messages on the RTREE virtual table. Make the "fs" virtual table used for testing available on windows. (check-in: c0b90d75a8 user: drh tags: trunk) | |
| 16:43 | Add the ability to disable transitive constraints using the sqlite3_test_control(SQLITE_TESTCTRL_OPTIMIZATIONS) interface. (Closed-Leaf check-in: 593d67c8b0 user: drh tags: transitive-constraints) | |
| 16:18 | Avoid unnecessary collating sequence and affinity restrictions on the use of transitivity. Add test cases to show that the restrictions are not needed. (check-in: 56549f4566 user: drh tags: transitive-constraints) | |
| 15:05 | Make more aggressive use of transitivity in optimizing queries. Add a test case. (check-in: d96762841a user: drh tags: transitive-constraints) | |
| 03:18 | Enhance RTree virtual table creation error messages that involve the getNodeSize() function. (Closed-Leaf check-in: 652233d646 user: mistachkin tags: rtreeErrMsg) | |
| 03:18 | Make the 'fs' virtual table module portable to Windows. (Closed-Leaf check-in: dd473cae5b user: mistachkin tags: fsVfsWin) | |
| 00:08 | Improved comments explaining the operation of the findTerm() utility routine in where.c. Increase the maximum number of levels of transitivity from 4 to 11. (check-in: fe152f8b04 user: drh tags: transitive-constraints) | |
|
2013-01-16
| ||
| 20:33 | Fix the activate_extensions pragma so that it is a no-op when the required argument is omitted. (check-in: 6195ebd833 user: drh tags: trunk) | |
| 17:08 | Enhance the query planner to exploit transitivity of join constraints in a multi-way join. (check-in: 13171eb5dc user: drh tags: transitive-constraints) | |
| 00:46 | Improvements to query planning for joins: Avoid unnecessary calls to "optimal scan" checks in cases where table reordering is not possible. Make sure optimal scan checks are carried out for CROSS JOINs and LEFT JOINs. (check-in: d5ebb78778 user: drh tags: trunk) | |
|
2013-01-15
| ||
| 18:49 | Fix a missing word in a comment. Enhance the "wheretrace" debugging output to show the estimated cost of each table option while planning the join order. (check-in: ac4e119a87 user: drh tags: trunk) | |
