another bugfix upstream release. please signoff.
SQLite version 3.6.12 is now available on the SQLite website
During release testing for 3.6.12, we stumbled over a critical bug
that has existed in SQLite since version 3.4.0. This bug will cause
corruption of in-memory databases if an incremental vacuum is rolled
back. The corruption is virtually guaranteed if you rollback an
incremental vacuum in an in-memory database. Presumably not many
people are doing that or we would have seen this sooner. As far as we
are aware, incremental vacuum works correctly for on-disk databases.
We will continue to study this issue over the next weeks and release
additional patches if we find new problems.
A manual code review uncovered another bug in the lookaside memory
allocator which can result in a segfault when shared cache is
enabled. At the very least, users of shared cache should disable
lookaside memory. A better solution is to update to version 3.6.12.
New features added to version 3.6.12 include the
sqlite3_unlock_notify() interface and the reverse_unordered_selects
PRAGMA. Additional information about both is available on the website.
Because of the incremental vacuum and lookaside memory allocator
issues identified above, we recommend that everyone update to SQLite
