Do not journal the locking page which doing an autovacuum. Similar to the problem of #1432 except that this one occurs on autovacuum instead of vacuum. An assert() has been added to catch any future incidents of this type. (CVS 2704) check-in: 5b6dc12b 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

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

While doing a transaction comment, use fdatasync() instead of fsync() in cases there the file size is unchanged. (CVS 2673) check-in: 3c555a87 user: drh tags: trunk
12:37
Fix another test to account for SUM() returning integer rather than float. (CVS 2672) check-in: bc723235 user: drh tags: trunk
11:04
Fix typos in documentation. Ticket #1239. (CVS 2671) check-in: 73fbb8d9 user: drh tags: trunk

Fix a comment in sqlite.h. Ticket #1321. (CVS 2670) check-in: ed4e9e75 user: drh tags: trunk
10:37
The SUM() aggregate function returns an integer result if all inputs are integers. Any single non-integer input causes the result to be a floating point value. (CVS 2669) check-in: 21adf4bd user: drh tags: trunk
02:00
Changes to comments only in sqliteInt.h. No changes to code. (CVS 2668) check-in: cc2a6165 user: drh tags: trunk

2005-09-07
23:05

22:48
More bug fixes. But there are still tests that fail. (CVS 2664) check-in: 7e85a162 user: drh tags: trunk
22:09
Bug fixes in aggregate processing. Fewer tests fail. (CVS 2663) check-in: c3ac5859 user: drh tags: trunk
21:22
Rewrite the aggregate handling logic so that it runs in O(1) space. This is the first cut at the code. Many regression tests fail. (CVS 2662) check-in: 17039ec3 user: drh tags: trunk
2005-09-06
21:40
Changes to reduce the amount of stack space required. (CVS 2661) check-in: b86bd70f user: drh tags: trunk

2005-09-05
20:35

12:16
All regression tests now pass with the new bounded-memory sort code. There is still lots of opportunity for optimization, however. (CVS 2654) check-in: 81259a01 user: drh tags: trunk
03:07
Sorting is now done using a sorting index rather than loading the entire result set into memory and doing a merge sort. The old merge sort technique was a carry-over from SQLite version 1. The new method uses a bounded amount of memory and scales to much larger result sets. There are still errors: some 39 regression tests fail. (CVS 2653) check-in: 09db0a24 user: drh tags: trunk
2005-08-31

2005-08-28
17:00
The LIKE optimization does the right thing when collating sequences are present. LIKE expressions where the left-hand side has COLLATE NOCASE are optimized in the default case. (CVS 2637) check-in: ef84ff79 user: drh tags: trunk
01:38
Improvements to the formatting and layout of the code in the previous checkin. (CVS 2636) check-in: 73b430de user: drh tags: trunk
