Oops: part of the fix for ticket #3015 got included with this check-in by mistake. (CVS 4917) check-in: 50de87dc user: drh tags: trunk
2008-03-25
17:23
Modify the {quote: IdxDelete} opcode so that it takes an array of registers rather than a record formed using {quote: MakeRecord.} This avoids a needless packing and unpacking of the record to be deleted. (CVS 4916) check-in: ee381b43 user: drh tags: trunk
16:16
Test string values passed to bind_text() and result_text() for a nul-terminator. (CVS 4915) check-in: 24c3ebc0 user: danielk1977 tags: trunk

00:22

2008-03-24
12:51

17:29
Better integrate the new malloc related instrumentation with the test infrastructure. (CVS 4904) check-in: d2140cae user: danielk1977 tags: trunk
