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) | |

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) | |

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) | |

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) | |
