11:11
Check-in (6450) introduced the possibility of calling memset() with a negative 3rd argument. This fixes that bug. Ticket #3777. (CVS 6452) check-in: 8ca612c4 user: drh tags: trunk
2009-04-05
15:18
Fix a segfault in Lemon that occurs if the input grammar does not define a type for tokens. This does not effect SQLite since the SQLite grammar does define a type for tokens. (CVS 6451) check-in: 4424aee9 user: drh tags: trunk
12:22
Additional code to make sure and to assert that memory allocations have 8-byte alignment. Ticket #3777. (CVS 6450) check-in: 208382e0 user: drh tags: trunk

01:43

18:32
Fix the sqlite3_prepare() family of interfaces so that they zero the *ppStmt value even on an SQLITE_MISUSE return. Make it clear in the documentation that the ppStmt parameter cannot be zero. (CVS 6441) check-in: 23bf9f26 user: drh tags: trunk

23:23
In the unix-backend, when simulating an I/O error on an unlock operation, still mark the connection as unlocked to avoid a future assert(). (CVS 6401) check-in: fb35cff8 user: drh tags: trunk

11:49
Ensure that the test vfs in test_journal.c zeroes sqlite3_file.pMethods if an xOpen() call fails. Similar problem to that fixed by #6384. This was a problem with test code, not SQLite itself. (CVS 6387) check-in: 45ae830d user: danielk1977 tags: trunk
2009-03-25

04:33

02:34
Fix compiler warning in MSVC. (CVS 6371) check-in: 83a4d5b3 user: shane tags: trunk
