Documentation changes in preparation for the release of 3.2.6. (CVS 2698) check-in: 243f455c user: drh tags: trunk

Undo check-in (2694). (CVS 2697) check-in: 6017b196 user: drh tags: trunk
02:38
Fix a whole host of newly discovered memory leaks the occur after a failure of realloc(). (CVS 2696) check-in: 4686d649 user: drh tags: trunk
00:27
Fix a memory leak: a failure to deallocate the P3 parameter on a call to sqlite3VdbeChangeP3. (CVS 2695) check-in: 714254cb user: drh tags: trunk
2005-09-15
21:24
The table_info pragma now gives the order of columns in the primary key. (CVS 2694) check-in: 9b60f48d user: drh tags: trunk
2005-09-13
16:12
Correct the sense of a test for SQLITE_DEBUG on the resent NDEBUG change. Ticket #1425 (CVS 2693) check-in: 81fdffdf user: drh tags: trunk
07:00
Updates to the documentation on the TCL bindings. (CVS 2692) check-in: 94aa2d32 user: drh tags: trunk
00:02
Fix a comment typo in the previous check-in. (CVS 2691) check-in: 49c95280 user: drh tags: trunk
00:00
Automatically set the NDEBUG preprocessor macro unless SQLITE_DEBUG is set. In this way, assert() statements become opt-in rather than opt-out. (CVS 2690) check-in: 2ec2bd85 user: drh tags: trunk
2005-09-12
23:03
Bug fix in the new COUNT(DISTINCT) logic. Ticket #1420. (CVS 2689) check-in: 37116550 user: drh tags: trunk
2005-09-11
11:56
COUNT(DISTINCT x) is now fully functional, though it could benefit from additional testing. (CVS 2688) check-in: 2f397bd8 user: drh tags: trunk
02:03
The ".dump" command from the shell correctly saves the state of the sqlite_sequence and sqlite_stat1 tables, if they exist. Ticket #1419. (CVS 2687) check-in: 3f191cf4 user: drh tags: trunk
2005-09-10
22:40
The shell does not output the sqlite_stat1 table on .dump or .schema. The ANALYZE command now gathers statistics on tables that have only a single index because this sometimes helps when reordering tables in a join. (CVS 2686) check-in: 26565b89 user: drh tags: trunk
16:46
Add the experimental EXPLAIN QUERY PLAN diagnostic capability. (CVS 2685) check-in: 986efb7b user: drh tags: trunk
15:35

15:28
Use of the CROSS keyword in a join prevents table reordering. Ticket #1414. (CVS 2683) check-in: 415b8b24 user: drh tags: trunk
2005-09-09
10:46
Enhanced disk-full tests. (CVS 2682) check-in: 0288fa5d user: drh tags: trunk

Detect errors returned by SetFilePointer on windows. (CVS 2681) check-in: bc8c33f9 user: drh tags: trunk
01:33
Infrastructure for the DISTINCT keyword in aggregate functions. But it does not work yet. If you try to use it you get an error message. (CVS 2680) check-in: 4d62e36f user: drh tags: trunk
01:32
Defend against disk I/O errors that happen during an sqlite3OsSeek(). (CVS 2679) check-in: 461e3a0a user: drh tags: trunk

SUM returns NULL when it has no inputs. Ticket #1413. (CVS 2678) check-in: 62818594 user: drh tags: trunk
19:45
A SUM() of all NULLs returns NULL. A SUM() of nothing return 0. A SUM() of a mixture of NULLs and numbers returns the sum of the numbers. Ticket #1413. (CVS 2677) check-in: 2e6230ed user: drh tags: trunk
19:01
Remove a C++ism that snuck in on one of the reason changes. (CVS 2676) check-in: 48f6a331 user: drh tags: trunk

Remove a few unused variables detected by Borland C. Ticket #1412. (CVS 2675) check-in: cdfe372a user: drh tags: trunk
