2008-07-15
22:59
Work around bugs in older versions of the OS/2 conversion library by trying to minimize calls to UniCreateUconvObject() etc. Use global uconv objects instead. (CVS 5418) check-in: 80e42183 user: pweilbacher tags: trunk
21:32

2008-07-14
20:43
Delete all fts3 index data the table becomes empty. Previously, deleting all rows from an fts3 table would leave a bunch of index data describing the terms of the original data, plus deletions of those terms, perhaps with some amount of it merged together so the deletions knocked out the originals. Even when all rows were deleted that original data would hang out, though eventually it would mostly be overwritten if new data contained the same set of terms.

15:37
Have the rtree extension publish two virtual table types: "rtree" and "rtree_i32". rtree_i32 stores coordinate data as 32-bit signed integers. rtree uses 32-bit real (floating point) values. (CVS 5410) check-in: c060a9a6 user: danielk1977 tags: trunk
15:11
Remove the malloc2.test script since it was designed for use in versions of SQLite that predate SQLite's ability to recover from out-of-memory errors automatically. Removing this script causes no reduction in test coverage and removes potential problems reported by ticket #3213. (CVS 5409) check-in: 5bfc9625 user: drh tags: trunk
12:52
Write sqlite3_initialize() calls in sqlite3_malloc() within SQLITE_OMIT_AUTOINIT. Ticket #3217. (CVS 5408) check-in: 4961b0bb user: drh tags: trunk

2008-07-11
21:02

Additional test coverage for the btree module. Remove the failsafe() macro and replace it with ALWAYS() and NEVER(). (CVS 5395) check-in: d7e2f0d2 user: drh tags: trunk
13:53
Fix minor problems in the test scripts and harness. (CVS 5394) check-in: c9ffbfe3 user: drh tags: trunk
03:38
Remove an extra zeroPage() call that was left in the previous check-in by mistake. Ticket #3209. (CVS 5393) check-in: c45d578e user: drh tags: trunk
03:34
Make the btree layer robust when faced with a corrupt database that contains duplicate entries on the freelist. Ticket #3209. (CVS 5392) check-in: 30825f74 user: drh tags: trunk
02:21
