100 check-ins occurring around 71a71cef5b3c9774.

2005-09-13
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
Avoid a memory leak and/or assertion failure when parsing a table declaration that contains a duplicate column name. Ticket #1418. (CVS 2684) (check-in: f4342774 user: drh tags: trunk)
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)
10:17
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)
2005-09-08
20:37
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)
14:17
Remove a few unused variables detected by Borland C. Ticket #1412. (CVS 2675) (check-in: cdfe372a user: drh tags: trunk)
12:57
Aggregates with GROUP BY can sometimes return no result rows. (CVS 2674) (check-in: 0c3e368d user: drh tags: trunk)
12:38
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)
10:58
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)
01:58
Optimizations and refinements. Improvements to test coverage. (CVS 2667) (check-in: 7283f7c2 user: drh tags: trunk)
00:13
All regression tests now pass. But I am sure there must still be problems. New tests need to be added. (CVS 2666) (check-in: bcc7d722 user: drh tags: trunk)
2005-09-07
23:05
More bug fixes. All of the "quick" tests pass. The full test suite still shows problems. (CVS 2665) (check-in: a1b6d910 user: drh tags: trunk)
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)
20:36
Cleanup the processing of MEM_Agg elements. (CVS 2660) (check-in: 7ecf3654 user: drh tags: trunk)
10:26
Fix ANALYZE so that it works even if the empty_result_callbacks pragma is enabled. Ticket #1409. (CVS 2659) (check-in: bfdaef12 user: drh tags: trunk)
2005-09-05
20:35
Make due with "sub()" instead of "gsub()" in awk scripts so that builds will work on Solaris which will runs an archiac version of AWK. (CVS 2658) (check-in: 449a7895 user: drh tags: trunk)
20:06
Fix bugs introduced by checkin (2656) and do some modest code enhancements. (CVS 2657) (check-in: 7b56763a user: drh tags: trunk)
19:08

2005-09-01
17:47
Fix over-aggressive optimization of ORDER BY as reported on the mailing list. (CVS 2655) (check-in: efbb4bc8 user: drh tags: trunk)
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
18:20

02:46
Update the FAQ to include an entry about binary versus decimal numbers. (CVS 2648) (check-in: 0bbe73fc user: drh tags: trunk)
01:49
Adding the first cut of the optimizer overview document. (CVS 2647) (check-in: 4c8d0a4c user: drh tags: trunk)
2005-08-30
22:44
Adjust the makefile for new optimizer documentation. (CVS 2646) (check-in: 14668c85 user: drh tags: trunk)
22:44
Initial work on documentation describing the optimizer. (CVS 2645) (check-in: 5cebd7ba user: drh tags: trunk)

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)

13:47
More test coverage improvements. (CVS 2605) (check-in: e559e810 user: drh tags: trunk)

Increased test coverage. Some malloc tests now fail though this is believed to be an instrumentation problem not a real error. (CVS 2604) (check-in: f786f37a user: drh tags: trunk)
2005-08-19
