dovecot - Feb 2017 - Released Pigeonhole v0.4.17.rc1 for Dovecot v2.2.28.rc1.

Hello Dovecot users,

Several bugs were found in the course of the last few months, but no new
features were created. So, this will be strictly a bug-fixing release.
The previous Pigeonhole release should still work with the new Dovecot
release, which means you are not required to upgrade. However, my advice
would be to upgrade once this release candidate matures into a final
release, since at least the first bug listed below is pretty severe.

Changelog v0.4.17:

- LDA Sieve plugin: Fixed handling of an early explicit keep during
  multiscript execution. Action side-effects and the message snapshot
  would be lost at the final stage where the implicit keep is
  evaluated. This could result in the IMAP flags assigned to the
  message to be forgotten or that headers modified by the "editheader"
  extension would revert to their original state.
- file script storage: Amended the up-to-date time stamp comparison for
  on-disk binaries to include nanoseconds. This will fix problems
  occurring when both binary and script are saved within the same
  second. This fix is ineffective on older systems that have no support
  for nanoseconds in stat() timestamps, which should be pretty rare
  nowadays.
- file script storage: Improve saving and listing permission error to
  include more details.
- imapsieve plugin: Make sure "INBOX" is upper case in static mailbox
  rules. Otherwise, the mailbox name would never match, since matching
  is performed case-sensitively and Dovecot only returns the
  upper-cased "INBOX".
- imapsieve plugin: Fixed assert failure occurring when used with
  virtual mailboxes.
- doveadm sieve plugin: Fixed crash when setting Sieve script via
  attribute's string value.

The release is available as follows:

Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for
more information. Have fun testing this release candidate and don't
hesitate to notify me when there are any problems.

Also, I guess we should wait longer than 0 msecs. I'll try and see if I can
replicate this.

Hi!

The bug is probably in dovecot core, and not in pigeonhole. I wasn't
able to yet try and replicate this issue.
