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: 2ec2bd8574 user: drh tags: trunk) | |
|
2005-09-12
| ||
| 23:03 | Bug fix in the new COUNT(DISTINCT) logic. Ticket #1420. (CVS 2689) (check-in: 37116550d3 user: drh tags: trunk) | |
|

| 11:56 | COUNT(DISTINCT x) is now fully functional, though it could benefit from additional testing. (CVS 2688) (check-in: 2f397bd814 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: 3f191cf497 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: 26565b8931 user: drh tags: trunk) | |
| 16:46 | Add the experimental EXPLAIN QUERY PLAN diagnostic capability. (CVS 2685) (check-in: 986efb7b12 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: f43427742b user: drh tags: trunk) | |
| 15:28 | Use of the CROSS keyword in a join prevents table reordering. Ticket #1414. (CVS 2683) (check-in: 415b8b2462 user: drh tags: trunk) | |

| 10:46 | Enhanced disk-full tests. (CVS 2682) (check-in: 0288fa5d25 user: drh tags: trunk) | |
| 10:17 | Detect errors returned by SetFilePointer on windows. (CVS 2681) (check-in: bc8c33f94c 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: 4d62e36fe3 user: drh tags: trunk) | |
| 01:32 | Defend against disk I/O errors that happen during an sqlite3OsSeek(). (CVS 2679) (check-in: 461e3a0a27 user: drh tags: trunk) | |

| 20:37 | SUM returns NULL when it has no inputs. Ticket #1413. (CVS 2678) (check-in: 6281859425 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: 2e6230edfd user: drh tags: trunk) | |
| 19:01 | Remove a C++ism that snuck in on one of the reason changes. (CVS 2676) (check-in: 48f6a331ef user: drh tags: trunk) | |
| 14:17 | Remove a few unused variables detected by Borland C. Ticket #1412. (CVS 2675) (check-in: cdfe372a95 user: drh tags: trunk) | |
| 12:57 | Aggregates with GROUP BY can sometimes return no result rows. (CVS 2674) (check-in: 0c3e368d47 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: 3c555a8749 user: drh tags: trunk) | |
| 12:37 | Fix another test to account for SUM() returning integer rather than float. (CVS 2672) (check-in: bc723235e6 user: drh tags: trunk) | |
| 11:04 | Fix typos in documentation. Ticket #1239. (CVS 2671) (check-in: 73fbb8d968 user: drh tags: trunk) | |
| 10:58 | Fix a comment in sqlite.h. Ticket #1321. (CVS 2670) (check-in: ed4e9e751b 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: 21adf4bd99 user: drh tags: trunk) | |
| 02:00 | Changes to comments only in sqliteInt.h. No changes to code. (CVS 2668) (check-in: cc2a61650e user: drh tags: trunk) | |
| 01:58 | Optimizations and refinements. Improvements to test coverage. (CVS 2667) (check-in: 7283f7c29d 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: bcc7d722ce 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: a1b6d910cd user: drh tags: trunk) | |
| 22:48 | More bug fixes. But there are still tests that fail. (CVS 2664) (check-in: 7e85a162d0 user: drh tags: trunk) | |
| 22:09 | Bug fixes in aggregate processing. Fewer tests fail. (CVS 2663) (check-in: c3ac58592f 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: 17039ec3ff user: drh tags: trunk) | |
|
2005-09-06
| ||
| 21:40 | Changes to reduce the amount of stack space required. (CVS 2661) (check-in: b86bd70f30 user: drh tags: trunk) | |
| 20:36 | Cleanup the processing of MEM_Agg elements. (CVS 2660) (check-in: 7ecf3654aa 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: bfdaef1224 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: 449a789599 user: drh tags: trunk) | |
| 20:06 | Fix bugs introduced by checkin (2656) and do some modest code enhancements. (CVS 2657) (check-in: 7b56763a8b user: drh tags: trunk) | |
| 19:08 | Use the unicode API to win32 where available. Tickets #1407, #1396, #1331, #1243, #1206 (CVS 2656) (check-in: 3ec58c673a user: drh tags: trunk) | |

| 17:47 | Fix over-aggressive optimization of ORDER BY as reported on the mailing list. (CVS 2655) (check-in: efbb4bc83c 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: 81259a01f1 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: 09db0a2424 user: drh tags: trunk) | |

| 13:13 | Explicit typecasts to silence nuisance compiler warnings. Ticket #1398. (CVS 2650) (check-in: 90712ea727 user: drh tags: trunk) | |
| 03:13 | Refinements to the optimizer overview and integration into the website. (CVS 2649) (check-in: ccd12e9e79 user: drh tags: trunk) | |
| 02:46 | Update the FAQ to include an entry about binary versus decimal numbers. (CVS 2648) (check-in: 0bbe73fccf user: drh tags: trunk) | |
| 01:49 | Adding the first cut of the optimizer overview document. (CVS 2647) (check-in: 4c8d0a4c26 user: drh tags: trunk) | |
|

| 22:44 | Adjust the makefile for new optimizer documentation. (CVS 2646) (check-in: 14668c85b8 user: drh tags: trunk) | |
| 22:44 | Initial work on documentation describing the optimizer. (CVS 2645) (check-in: 5cebd7ba3c user: drh tags: trunk) | |
| 20:12 | The CSV output mode does not sign-extend bytes where the high-order bit is set. Ticket #1397. (CVS 2644) (check-in: 528df777e5 user: drh tags: trunk) | |
| 19:30 | Fix printf.c so that it handles 10.0 correctly. (CVS 2643) (check-in: 0f7a53f78d user: drh tags: trunk) | |
| 00:54 | Minor code enhancements. (CVS 2642) (check-in: 4ab994a87e user: drh tags: trunk) | |
| 00:10 | Update the home page to brag about 150KiB code footprint when optional features are omitted. (CVS 2641) (check-in: 0e1ac1284c user: drh tags: trunk) | |
