Overview
| Comment: | Call fsync() right after ftruncate() when in journal_mode=TRUNCATE and when synchronous=FULL in order to ensure that transactions are durable across a power loss that happens moments after the commit. Proposed fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1072773. This is a cherry-pick of [3e922208b68563] |
