[Bug 1018579] Re: dovecot panic

2012-07-27 Thread Stéphane Graber 
As stated on IRC, I did a minimal regression check, getting a precise
container working with postfix and dovecot, sending a couple of test
e-mails, retrieving them from dovecot, then upgrading to the new
packages and testing again.

The race is apparently difficult to hit and doesn't have a clear test case. The 
patch was taken from upstream so it's hopefully sane.
Marking this bug verification-done on the basis that it's been waiting for 
almost 30 days and doesn't show any sign of regression.

Although the test case is vague, I'm going to go ahead and accept this.
Races are always tough.

2012-06-27 Thread Barry Warsaw 
So far, that patch does seem to fix the crashes, and dovecot appears to
be working again on my production 12.04 system.  I'll now submit a merge
proposal and SRU request.
