2011-08-31
| ||
| 23:57 | Avoid using uninitialized variables after failures in the merge sort code. check-in: 2869ed28 user: drh tags: trunk | |
| 21:01 | Formerly, we enabled fdatasync() on linux only. But now we learn that fdatasync() is not supported on Android. So we disable fdatasync() on Linux too. It can be reenabled at compile-time for those who really need it. check-in: 70b5b309 user: drh tags: trunk | |
| 20:47 | Add the SQLITE_MAX_SCHEMA_RETRY compile-time option to the set of options understood by "PRAGMA compile_options;" and by the "sqlite_compileoption_used()" function. check-in: 1b124af4 user: drh tags: trunk | |
| 19:40 | The server1.test script should only run if mutexes are functional. Fix to the #ifdef change of check-in [9e6a4c1473]. check-in: 64898485 user: drh tags: trunk | |

| 17:46 | Backslash escaping is not working right in tostr.awk on the latest ubuntu. The easiest fix is to simply not use any backslashes in the spaceanal.tcl script. check-in: df550066 user: drh tags: trunk | |
| 13:27 | Add checks to make sure cells in corrupt database files do not overflow a page when doing autovacuum. Problem detected by valgrind. check-in: d0b347b4 user: drh tags: trunk | |

| 02:15 | About a 3% improvement in the performance of OP_Column. check-in: edff9d4a user: drh tags: experimental | |
| 00:19 | Correctly display P4_ADVANCE values on opcode traces. Mark an always-taken branch in OP_Column as such. check-in: 087dc960 user: drh tags: experimental | |

| 13:52 | Merge branches branch-3.7.2 and stat3-enhancement into a new branch for testing purposes. check-in: 0df04f92 user: drh tags: stat3-3.7.2 | |
| 13:16 | Merge the stat3-enhancement branch with trunk, but keep the resulting merge in a separate branch for now. check-in: 63f2c785 user: drh tags: stat3-trunk | |
| 00:34 | Create a new pager type, PAGER_SORTER, for use in the external merge sort. Such pagers are always held in memory but do report when they are under memory pressure by calling pagerStress. check-in: c71d7320 user: drh tags: trunk | |

| 01:42 | Add the sqlite3_quota_file() interface to test_quota.c. check-in: 2b7fe8e5 user: drh tags: trunk | |

| 15:12 | Fix some harmless compiler warnings. check-in: 46f5a68b user: drh tags: trunk | |

|
2011-08-23
| ||
| 23:41 | Simplifications to the SQLITE_PAGECACHE_BLOCKALLOC logic. Reduce the number of difficult-to-reach branches. check-in: d5d835fe user: drh tags: trunk | |
| 20:11 | If the application-defined openDirectory() function returns SQLITE_CANTOPEN, then silently ignore the error. This allows the chromium sandbox to disallow opening of directories without causing errors. check-in: 880b5115 user: drh tags: trunk | |
| 13:27 | Ifdef out routines in pcache1.c that are used only when SQLITE_PAGECACHE_BLOCKALLOC is defined. check-in: 0da292da user: drh tags: trunk | |

| 14:54 | When retrying a write() after an EINTR error on unix, be sure to also rerun the previous lseek(). Ticket [e59bdf6116036a] check-in: 21452f3a user: drh tags: trunk | |
|
2011-08-18
| ||
| 13:45 | Fix the stat3 analysis loader to be compatible with sqlite3_db_status(). Also fix some OOM issues with the stat3 analysis loader. Closed-Leaf check-in: eaf447ea user: drh tags: stat3-enhancement | |

| 02:07 | Allow the sqlite3VdbeJumpHere() routine to accept a negative or zero address if a prior memory allocation error has occurred. The new sqlite_stat3 logic needs this. check-in: 9650d796 user: drh tags: stat3-enhancement | |
| 01:15 | Add the analyze8.test test module for sqlite_stat3. check-in: 2c83ac89 user: drh tags: stat3-enhancement | |

|
2011-08-13

|
2011-08-10
| ||
| 01:52 | Make the openDirectory routine in os_unix.c overrideable so that it can be turned into a harmless no-op for the chromium sandbox. check-in: 6b236069 user: drh tags: trunk | |
|
2011-08-09
| ||
| 18:14 | Add command-line utilities "offsets.c" and "extract.c" for use in low-level analyzsis of database files. check-in: dfa22ed4 user: drh tags: trunk | |
|
2011-08-08
| ||
| 23:48 | In os_unix.c, do not open the directory containing the database file when the database file is opened. Instead, wait until time to fsync() the directory. And do not report an error if the open fails, since some systems (Ex: AIX and a chromium sandbox) are unable to open and fsync directories. check-in: 713b1b7d user: drh tags: trunk | |
| 23:18 | Allow the unlink() system call to be overridden in os_unix.c. check-in: 8d1b5c3a user: drh tags: trunk | |

|
2011-08-07
| ||
| 01:31 | Remove relevant elements from the sqlite_stat2 table when doing a DROP INDEX or DROP TABLE. check-in: 3c8f97ae user: drh tags: trunk | |

|
2011-08-06
| ||
| 19:48 | The sqlite_stat2.cnt field is parsed if it is present. But it is not yet used. A large comment added to analyze.c to explain the format of the ANALYZE system tables. check-in: 6d1e2372 user: drh tags: query-planner-tweaks | |
| 02:03 | Merge together the fork in the query-planner-tweaks branch. check-in: 2daab6bd user: drh tags: query-planner-tweaks | |

|
2011-08-05
| ||
| 22:31 | Bug fixes to the sample-count logic for STAT2. A few test cases added. check-in: e93c248c user: drh tags: query-planner-tweaks | |
| 21:13 | Add a column to the sqlite_stat2 table that contains the number of entries with exactly the same key as the sample. We do not yet do anything with this extra value. Some tests in analyze2.test are failing. check-in: eb434228 user: drh tags: query-planner-tweaks | |
| 01:09 | Allow the sqlite_stat2 table to contain a number of samples other than the default of 10. check-in: b9d41c34 user: drh tags: query-planner-tweaks | |
|
2011-08-03
| ||
| 22:06 | Merge the winopen-retry-logic branch into trunk. The biggest change here is to test scripts, which should now use such as copy_file and delete_file from tester.tcl rather than the raw file commands of TCL. check-in: b90c28be user: drh tags: trunk | |
| 21:46 | Merge the latest trunk changes into the sessions branch. check-in: c5709036 user: drh tags: sessions | |
| 21:32 | Avoid segfaulting on an incremental blob write if SQLITE_ENABLE_PREUPDATE_HOOK set but no pre-update hooks are defined. check-in: 62c44634 user: drh tags: sessions | |
| 16:40 | Update the OP_Move opcode to shift the pScopyFrom pointer of aliases when compiled with SQLITE_DEBUG. Ticket [d63523637517386191]. check-in: a2135ad1 user: drh tags: trunk | |
| 01:07 | Adjust the output row estimating logic when using STAT2. check-in: c8ba8855 user: drh tags: query-planner-tweaks | |
|

| 20:01 | Merge in the permutation changes from trunk. check-in: b30a5e30 user: drh tags: winopen-retry-logic | |
| 19:59 | Also exclude backcompat.test from inmemory_journal since inmemory_journal is not compatible with WAL mode. check-in: 861a5b62 user: drh tags: trunk | |
| 19:42 | Merge the latest trunk changes into the winopen-retry-logic branch. check-in: 8bef97a0 user: drh tags: winopen-retry-logic | |
| 19:30 | Omit backcompat.test from the journaltest permutation because it uses WAL mode which is incompatible with journaltest. check-in: 2bbf3150 user: drh tags: trunk | |
| 18:25 | Merge all the latest trunk changes into the apple-osx branch. check-in: 77376b33 user: drh tags: apple-osx | |
