340557 - Bugzilla should have atomic changesets ("transactions")

Status: RESOLVED DUPLICATE of bug 281354

(Bugzilla :: Creating/Changing Bugs, enhancement)

From bug 340530 comment 0:

vladd wrote that we don't have atomic bug changes. we simply log the timestamp,
which has 1 second resolution. So submitting each change individually within 1
second timeframe, or all at once, is really the same thing. so they aren't
atomic, so probably it's a slight issue, but then the non-atomic bug changes
are an issue by themselves.

vladd wrote you can certainly set 2 flags 0.5seconds apart, and there are 50%
chances that they'll look atomically in the DB log. you don't get atomicity by
increasing the timestamp resolution; what should we really have is a change ID
that auto-increments itself upon each atomic operation, and refer that ID for
each atomic change.

Yep, I agree.
