#1036: buildrequest can be multiply claimed on MySQL
--------------------+-------------------------------------------------------
Reporter: dustin | Owner:
Type: defect | Status: new
Priority: blocker | Milestone: 0.8.3
Version: 0.8.1 | Keywords: db
--------------------+-------------------------------------------------------
Even with InnoDB, it is not an error for two concurrent transactions to
alter the same row. The serialization is simple: the second transaction
to complete takes effect.
So updating {{{buildrequests.claimed_at}}} is not sufficient to actually
claim a buildrequest - in fact, we're seeing buildrequests multiply
claimed in https://bugzilla.mozilla.org/show_bug.cgi?id=592244.
