2013-02-13
| ||
| 13:42 | Enhancements to the query planner to make use of indices for ORDER BY even when IN constraints are in the WHERE clause. Add extended error codes for all SQLITE_CONSTRAINT errors. check-in: 7e14dc73 user: drh tags: sessions | |
| 01:00 | Allow an index to be used for sorting even if prior terms of the index are constrained by IN operators. check-in: 2cef8b68 user: drh tags: trunk | |
|
2013-02-12
| ||
| 22:20 | Improve memory allocation error handling on WinCE. check-in: cdbca259 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: b7222a2b user: drh tags: trunk | |
| 09:46 | Improve memory allocation error handling on WinCE. Closed-Leaf check-in: 09dfc0c9 user: mistachkin tags: wince | |
|
2013-02-11
| ||
| 13:47 | Add extended error codes for all SQLITE_CONSTRAINT errors. check-in: 939d8282 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: 3f674375 user: drh tags: constraint-error-codes | |
| 13:58 | Add extended error codes for constraint errors. check-in: 54611046 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: 71b6c260 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: b016b754 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: f78395c8 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: a917c1f0 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: 98bf668a user: drh tags: IN-with-ORDERBY | |

|
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: 497ee36c 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: ae565ff3 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: a6499c25 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: c2462a95 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: b4d94947 user: drh tags: trunk | |
|
2013-01-26
| ||

|
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: 7813b17d 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: 8ba951d1 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: 93b159da 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: 4e2bf575 user: drh tags: trunk | |
| 15:09 | Enhance the "showwal" utility program to show checksum failures on frames. check-in: a7f6d198 user: drh tags: trunk | |

|
2013-01-23
| ||
| 18:53 | Improved parsing of the arguments to the ".backup" command in the command-line shell. check-in: f1127e87 user: drh tags: trunk | |
| 18:44 | Fix a double-free() call that can occur when SQLITE_ENABLE_TREE_EXPLAIN is defined. check-in: 5bfb5967 user: drh tags: trunk | |
|
2013-01-20

| 03:18 | Make the 'fs' virtual table module portable to Windows. Closed-Leaf check-in: dd473cae 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: fe152f8b 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: 6195ebd8 user: drh tags: trunk | |
| 17:08 | Enhance the query planner to exploit transitivity of join constraints in a multi-way join. check-in: 13171eb5 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: d5ebb787 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: ac4e119a user: drh tags: trunk | |

2012-12-18
| ||
| 19:36 | Optimize the degenerate case of a FROM clause table name enclosed all by itself inside parentheses. Generate code as if the parentheses did not exist, rather than the old behavior of manifesting the parenthesized table into a transient table. Also, tag every FROM-clause SELECT subquery that is generated by a parenthesized FROM-clause expression using the SF_NestedFrom flag. The new SF_NestedFrom flag is not yet used for anything. check-in: 7fecced4 user: drh tags: trunk | |
