Add a test to make sure a database can be attached to a single handle twice if not in shared-cache mode. (check-in: 1c4984c6 user: dan tags: trunk)
15:02
If the root pages numbers of the internal schema are adjusted due to autovacuum on a DROP TABLE statement and that statement later aborts (for example, due to an OOM error) then reset the internal schema at the conclusion of the statement. Partial fix for ticket [564d412f15a]. (check-in: e493b093 user: drh tags: trunk)
13:18
Avoid unnecessary page cache allocations when move a page while autovacuuming an in-memory database, since the allocation might fail making it impossible to rollback the transaction. (check-in: 9a429349 user: drh tags: trunk)

2009-11-16
23:36
Make sure the output of sqlite3OsFullPathname is initialized even if the fails due to I/O or OOM errors. (check-in: e4943adb user: drh tags: trunk)
