X-Git-Tag: version-3.35.0~68
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e9cfe878439fdc1d23c21becf6a308399b14dfd3;p=thirdparty%2Fsqlite.git

When a sub-transaction is released, if no pages required by containing sub-transactions were journaled, truncate the statement journal. This prevents out of control statement journal growth in some cases.
