Make sure the result of sqlite3VdbeGetOp() is not used as an array following an OOM error, since after (6691) it might be a single-entry dummy opcode. (CVS 6724) check-in: 127b1398 user: drh tags: trunk
14:13
When building in debug mode with gcc, force the nullMem variable in function columnMem() to be aligned to an 8-byte boundary. Otherwise an assert() statement may fail. (CVS 6723) check-in: 3fd6c72d user: danielk1977 tags: trunk
2009-06-05
18:44

2009-06-04
19:06
Earlier detection of freelist corruption in the page allocation routines. (CVS 6718) check-in: e557c8e5 user: drh tags: trunk

16:14

2009-06-03
21:04
Change the pcache1.c implementation so that the "header" occurs at the end of page buffer, not at the beginning. This insures that the 20 bytes immediately following the page buffer are mapped if a read of the page buffer overruns due to a malformed cell. (CVS 6711) check-in: c54de1f5 user: drh tags: trunk
17:26
Add corruptD.test, a container for testing the "cell overflow" problem. Also shuffle a small amount of code in BtreeInitPage() to check that the page header pointer to the start of the cell offset array is set to a sane value. (CVS 6710) check-in: 7fa5d3cb user: danielk1977 tags: trunk
11:25
Define a set of constants to use as the "index" argument to sqlite3BtreeGetMeta and UpdateMeta. This makes some parts of the code easier to follow. (CVS 6709) check-in: 6dbf4eca user: danielk1977 tags: trunk

2009-06-01
19:53

18:18
Malloc for space to hold the Parse object in sqlite3_prepare() and friends. Or, if compiled with SQLITE_USE_ALLOCA, obtain space for the object from alloca(). (CVS 6702) check-in: c7c0c58e user: drh tags: trunk
17:10
Added assert to verify winMutex system is inited before "static" mutexes are used. (CVS 6701) check-in: b126013b user: shane tags: trunk

11:05
Workaround the need for internal API sqlite3BtreeCursorDb(). It was only being used for an assert() statement, which can be done differently. (CVS 6683) check-in: 5904af6e user: danielk1977 tags: trunk
01:00
Additional refinements to Expr handling. Restore compression of trigger expressions. Change Expr.zToken to Expr.u.zToken and added Expr.u.iValue. Remove an unnecessary ExprDup from CHECK constraint processing. And so forth. (CVS 6682) check-in: 4ac2bdfb user: drh tags: trunk
