2005-09-13
| ||
| 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 | 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 | |

|
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

| 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 | |

| 16:40 | Initialize a local variable to avoid a nuisance compiler warning. Ticket #1394. (CVS 2638) check-in: 9b914901 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 | |
| 03:03 | 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 | |
