23:20
Relax the locking requirements on BTree cursors. Any number of read and write cursors can be open at the same time now, but a write cannot occur as long as one or more read cursors are open.    Before this change, one or more read cursors could be open on a table, or a single write cursor, but not both. Both policies have the same desirable effect: they prevent writes to a table while a sequential scan of that table is underway. But the new policy is a little less restrictive. Both policies prevent an UPDATE from occurring inside a SELECT (which is what we want) but the new policy allows a SELECT to occur inside an UPDATE. (CVS 739) check-in: 8c2a0836 user: drh tags: trunk
2002-08-31
18:53

2002-08-29
23:59
If the database is locked when sqlite_open() is called, sqlite_exec() should still honor the busy callback and should return an error message together with the SQLITE_BUSY result code. (CVS 733) check-in: 78a0229a user: drh tags: trunk
2002-08-28
03:00
