|
2014-05-23
| ||
| 12:03 | In the command-line shell, if three or more interrupt signals (control-c) are received in a row without a response from sqlite3_interrupt() then call exit(1) immediately. This allows control-C to interrupt the shell even if it is stuck in a computation or loop that does not involve the VDBE. (check-in: b5cde571 user: drh tags: trunk) | |

| 08:21 | Fix the sqlite3_db_readonly() API so that it reports true if the database is readonly because the file format write version (byte 18 of the header) is too large. (check-in: 8d8af114 user: drh tags: trunk) | |
|
2014-05-20

| 15:16 | Changes to help ensure that a multiplication does not overflow when computing the number of bytes needed for a memory allocation, and cause a malfunction. No problems existing problems were discovered. However, these changes should help to ensure that no problems arise in the future. (check-in: 17349a49 user: drh tags: safer-malloc) | |
|
2014-05-16
| ||
| 20:24 | Rearrange some conditionals and add #if statements to make the code more testable. (check-in: 17afd770 user: drh tags: threads) | |
| 17:31 | Add a pair of sqlite3FaultSim(100) calls to vdbesort.c to facilitate testing of obscure and hard to reach error conditions. (check-in: cceac14f user: drh tags: threads) | |

| 14:17 | Repurpose the SQLITE_TESTCTRL_FAULT_INSTALL test-control to register a callback to be invoked by sqlite3FaultSim(). That test-control has been unused since 2008-06-20 and was never used in any official release. (check-in: 0d43a7ad user: drh tags: trunk) | |
| 12:18 | Use #ifdef logic to avoid an always-true branch when SQLITE_MAX_WORKER_THREADS=0 (check-in: 88cfe6d7 user: drh tags: threads) | |
|
2014-05-15

| 16:56 | Use #ifdef to omit code that is not used when SQLITE_MAX_WORKER_THREADS is zero. (check-in: 2e8d287d user: drh tags: threads) | |
|
2014-05-12
| ||
| 15:30 | In the sorter, only use large memory allocations if scratch memory has not been configured. Add #ifdefs to disable unused code when SQLITE_MAX_WORKER_THREADS is zero. Other sorter changes in support of testability. (check-in: d7e2b0d9 user: drh tags: threads) | |
|
2014-05-09
| ||
| 17:17 | Merge recent trunk changes into the orderby-planning branch. (Leaf check-in: 8d8609d6 user: drh tags: orderby-planning) | |
| 14:56 | Fix a misplaced #endif and a C99-ism in the unix VFS. (check-in: c8d384d1 user: drh tags: apple-osx) | |
| 13:27 | Fix compiler warnings. When forcing the delete of a WAL file, do not fail if the WAL files does not exist. All "veryquick.tcl" tests are now passing on Linux under the standard compile-time options. (check-in: eafd8aa1 user: drh tags: apple-osx) | |

|
2014-05-08
| ||
| 23:01 | Initial attempt to merge in all trunk changes over the previous 1.5 years. This check-in compiles but there are compiler warnings and "make test" segfaults after only running a few test modules. (check-in: 9411d7dc user: drh tags: apple-osx) | |
|
2014-05-07
| ||
| 21:16 | Include sqlite3rtree.h in the tsrc/ pile of source files during target_source in the main.mk makefile. (check-in: 116bed5a user: drh tags: trunk) | |
| 20:33 | Remove a superfluous variable initialization. (check-in: 68766f83 user: drh tags: trunk) | |
| 20:24 | A better fix for the group_concat() problem. (check-in: 1c086dee user: drh tags: trunk) | |
| 18:23 | Make sure the group_concat() function returns an empty string, not a NULL, if it has at least one input row. Fix for ticket [55746f9e65f8587]. (check-in: d01cedaa user: drh tags: trunk) | |
| 18:21 | Ensure that the sqlite3StrAccumAppend() routine is never called with a NULL second argument. Doing so is harmless when N==0, but it causes an assert() to fail that was placed to quiet static analyzers. (Closed-Leaf check-in: f03fbf37 user: drh tags: tkt-55746f9e) | |
| 18:08 | • Edit [0deac8737545a020|0deac873]: Move to branch tkt-55746f9e. (artifact: 44e6e266 user: drh) | |

| 17:19 | Make sure the group_concat() function returns an empty string, not a NULL, if it has at least one input row. Fix for ticket [55746f9e65f8587]. (check-in: 0deac873 user: drh tags: tkt-55746f9e) | |
| 16:58 | • New ticket [55746f9e] group_concat() returns NULL instead of an empty string. (artifact: cc9c07bc user: drh) | |
| 15:46 | Add the SQLITE_IOCAP_IMMUTABLE bit as a possible return value from the xDeviceCharacteristics method in the VFS. Add the "nolock" and "immutable" query parameters to URI filenames. (check-in: 1a0d7d3d user: drh tags: trunk) | |
| 15:32 | Fix nolock and immutable so that they work even if READONLY is requested. (Closed-Leaf check-in: e193aced user: drh tags: win32-none) | |
| 15:09 | Add test cases and documentation for the nolock and immutable query parameters. (check-in: 19d56cba user: drh tags: win32-none) | |
| 11:21 | • Edit [3ac75725a6673056|3ac75725]: Mark "Closed". (artifact: a6b05714 user: drh) | |
|
2014-05-06
| ||
| 15:28 | Experimental changes that reduce the size of Expr objects from 72 to 64 bytes each on x64 and from 48 to 44 bytes each on x32. (Leaf check-in: 8ad0a123 user: drh tags: smaller-expr) | |
|
2014-05-05
| ||
| 22:49 | Add the "omit_check_constraints" pragma that causes the check constraint expressions to be omitted from the parse tree. (Leaf check-in: f1a4bf01 user: drh tags: reduce-schema-size) | |
| 20:34 | Incorporate the latest trunk changes so that hopefully now this branch will build on beagleboard. (check-in: 2647b17d user: drh tags: reduce-schema-size) | |
| 20:33 | • Edit [35a9f3f1787ed20b|35a9f3f1]: Cancel tag "winHdr". (artifact: 635436f2 user: drh) | |
| 20:32 | Create new header file "os_setup.h" used to detect the operating system at compile-time, and "os_win.h" that contains windows-specific header in formation. (check-in: bd92e0f8 user: drh tags: trunk) | |
| 20:21 | Attempt to fix the build on beagleboard. (Closed-Leaf check-in: 3ac75725 user: drh tags: winHdr) | |
| 20:11 | • Edit [857f2baf9b722e4e|857f2baf]: Move to branch winHdr. (artifact: 90b29b47 user: drh) | |
| 19:57 | Try to reduce the amount of memory used to hold the schema when PRAGMA ignore_check_constraints is active. (check-in: 35a9f3f1 user: drh tags: reduce-schema-size) | |
|
2014-05-03
| ||
| 13:53 | Get SQLITE_MUTEX_STATIC_APP1 and _APP2 working for the debugMutex implementation. (check-in: f49ba1c9 user: drh tags: threads) | |
| 12:00 | Add two new static mutexes, SQLITE_MUTEX_STATIC_APP1 and _APP2, for use by the application program. First intended use is in test programs for the memory allocation logic where one does not want to allocating a _FAST or _RECURSIVE mutex since that would involve using the memory allocation system under test. (check-in: 13686035 user: drh tags: threads) | |
| 11:22 | Add the SQLITE_DEFAULT_WORKER_THREADS compile-time option. Fix a NULL-pointer dereference that can occur following OOM. (check-in: e0dea89b user: drh tags: threads) | |
|
2014-05-02
| ||
| 18:46 | Do not run the vdbeRecordCompareDebug() assert if pKeyInfo->db is NULL since in that case there would be no way to check for a memory allocation failure. (check-in: 63ed2d6a user: drh tags: threads) | |
| 17:33 | Simplify assert() statements used to verify correct operation of record comparison routines. (check-in: 3300d62d user: drh tags: orderby-planning) | |
| 16:22 | Failure to extend a temp file for use with mmap() in vdbesort.c is benign. (check-in: d4d39638 user: drh tags: orderby-planning) | |
| 15:25 | Fix a faulty assert() statement. (check-in: 9196ce40 user: drh tags: orderby-planning) | |
| 13:15 | • Edit [2029a396dcdb928f|2029a396]: Mark "Closed". (artifact: 9f15be6e user: drh) | |
| 13:15 | • Edit [05e6e16cb28c9ffb|05e6e16c]: Mark "Closed". (artifact: 1e4dfa5d user: drh) | |
| 13:09 | Merge latest trunk enhancements and fixes into the orderby-planning branch. (check-in: 84862d3a user: drh tags: orderby-planning) | |
| 00:09 | Add a comment explaining why WhereLoop cost adjustments are omitted for skip-scan loops. (check-in: 3bc43594 user: drh tags: trunk) | |
|
2014-05-01
| ||
| 20:24 | Add #ifdefs for test coverage. Add a testcase(). (check-in: be2702ce user: drh tags: trunk) | |
| 01:49 | Take out the special handling of nolock=true in os_win.c and add it to pager.c, so that it works for all VFSes. Add the pPager->noLock boolean for clarity. (check-in: 725c1c14 user: drh tags: win32-none) | |
| 01:20 | Avoid unnecessary xUnlock operations on temp file. (check-in: 1829c38c user: drh tags: win32-none) | |
| 01:13 | Add the immutable=TRUE query parameter and SQLITE_IOCAP_IMMUTABLE, either of which prevents locking of the database and omits tests for existance of journal files. (check-in: 71f152c8 user: drh tags: win32-none) | |
