| 14:31 | Test enhancements, especially to the new compound-SELECT merge logic. (CVS 5305) (check-in: edf7f518 user: drh tags: trunk) | |
| 02:47 | If a unique index covers any prefix of the ORDER BY clause then let it satisfy the ORDER BY clause. (CVS 5301) (check-in: e53403b6 user: drh tags: trunk) | |

|
2008-06-24
| ||
| 12:46 | Fix a problem in sqlite3ExprIsInteger() causing failures on select1-4.9.2. Other bug fixes in compound-merge. The compound-merge is still disabled in this check-in using "#if 0" due to additional bugs. (CVS 5295) (check-in: 95037e6d user: drh tags: trunk) | |

| 00:16 | Add some test logic to the new memory allocation subsystem. (Lots more needed.) The test suite is currently indicating memory leaks, though it is unclear if this is a true code problem or just an instrumentation problem. (CVS 5240) (check-in: cb1f11cd user: drh tags: trunk) | |
|
2008-06-18
| ||
| 18:12 | Added support for scratch-memory lookaside allocations. Largely untested. Added calls to sqlite3_initialize() within malloc APIs. (CVS 5237) (check-in: 383a7860 user: drh tags: trunk) | |
| 15:34 | Make sure aggregate functions can take any number of arguments up to the limit imposed by SQLITE_LIMIT_FUNCTION_ARGS. Ticket #3179. Modify the group_concat() function to take an unlimited number of arguments in order to facilitate testing this behavior. (CVS 5233) (check-in: 70c6739f user: drh tags: trunk) | |

| 02:01 | Remove mem3.c and mem5.c from the amalgamation for the time being, since they do not currently work. We will add them back later once they are fixed. (CVS 5229) (check-in: 39b4e1ff user: drh tags: trunk) | |
|
2008-06-17
| ||
| 15:12 | Add internal interfaces: PageMalloc/PageFree and ScratchMalloc/ScratchFree. (CVS 5226) (check-in: 3e797d0f user: drh tags: trunk) | |
| 01:03 | Do not allow a VACUUM to try to change the page_size on an encrypted database. (CVS 5225) (check-in: d49e5020 user: drh tags: trunk) | |
|
2008-06-16
| ||
| 20:51 | Clean up obfuscated code in sqlite3_table_column_meta_data(). Be sure to invoke sqlite3_initialize() within sqlite3_mprintf(). (CVS 5224) (check-in: bb4edb53 user: drh tags: trunk) | |
|
2008-06-15
| ||
| 02:51 | Continuing work on the new memory allocation subsystem. Added routines for temporary memory allocation. Right the btree balance mechanism to only do one temporary allocation at a time. (CVS 5220) (check-in: 65fe7b62 user: drh tags: trunk) | |
|
2008-06-14
| ||
| 16:56 | Continuing progress on the new memory allocation subsystem. Added the sqlite3_mem_methods structure for defining new memory allocators at run-time. (CVS 5219) (check-in: f00305f4 user: drh tags: trunk) | |
|
2008-06-13
| ||
| 18:24 | Progress toward implementation of sqlite3_config() and a rework of the mutex and memory allocation subsystems. This is an incremental check-in. (CVS 5218) (check-in: a03c5af1 user: drh tags: trunk) | |
|
2008-06-12
| ||
| 18:17 | Enhance zeroblob tests to use the sqlite3_memory_highwater in order to double-check that no large allocations are occurring. (CVS 5217) (check-in: e93079be user: drh tags: trunk) | |
| 18:05 | Fix a typo in the date/time function tests. Add additional cases to the zeroblob tests to make sure sqlite3_bind_zeroblob() does not use excess memory. (CVS 5216) (check-in: c1006fb1 user: drh tags: trunk) | |
| 16:35 | Convert the date/time functions to work with milliseconds since the julian epoch internally (instead of days since the epoch) in order to avoid problems with floating-point roundoff error. The interface is unchanged. (CVS 5215) (check-in: ed35f8a9 user: drh tags: trunk) | |
| 13:50 | Avoid unnecessary float->text->float conversions in date/time processing. This change necessary to reproduce the problem reported by BareFoot. (CVS 5213) (check-in: 6ec4d765 user: drh tags: trunk) | |
| 12:51 | Add the ability to disable the "localtime" modifier in the date/time functions. This might be necessary for systems that do not support localtime_r() or localtime_s(). (CVS 5212) (check-in: 12f3ba11 user: drh tags: trunk) | |
| 12:40 | Remove obsolete code from the test_osinst.c module. (CVS 5211) (check-in: 699cec66 user: drh tags: trunk) | |
| 12:38 | Copy the latest VFS changes into the OS/2 implementation. This is a blind edit - I have no way to compile or test OS/2. (CVS 5210) (check-in: b60508cc user: drh tags: trunk) | |
| 00:07 | Additional refinements to the new sqlite3_initialize() interface design. (CVS 5206) (check-in: 14a9b945 user: drh tags: trunk) | |

|
2008-06-10
| ||

|
2008-06-06
| ||
