http://dovecot.org/releases/2.2/rc/dovecot-2.2.13.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.13.rc1.tar.gz.sig
There have been a ton of smaller and some larger changes since v2.2.12, so I thought I'd first make a RC release and the final v2.2.13 tomorrow. Please try it out!
BTW. I've read most of the mails again in Dovecot mailing list, but there are still a few reported bugs I decided to leave until later. Anyway feel free to re-send any bug reports for things that haven't been fixed in v2.2.13 yet.
* Fixed a DoS attack against imap/pop3-login processes. If SSL/TLS
handshake was started but wasn't finished, the login process
attempted to eventually forcibly disconnect the client, but failed
to do it correctly. This could have left the connections hanging
arond for a long time. (Affected Dovecot v1.1+)
+ mdbox: Added mdbox_purge_preserve_alt setting to keep the file
within alt storage during purge. (Should become enforced in v2.3.0?)
+ fts: Added support for parsing attachments via Apache Tika. Enable
with: plugin { fts_tika = http://tikahost:9998/tika/ }
+ virtual plugin: Delay opening backend mailboxes until it's necessary.
This requires mailbox_list_index=yes to work. (Currently IMAP IDLE
command still causes all backend mailboxes to be opened.)
+ mail_never_cache_fields=* means now to disable all caching. This may
be a useful optimization as doveadm/dsync parameter for some admin
tasks which shouldn't really update the cache file.
+ IMAP: Return SPECIAL-USE flags always for LSUB command.
- pop3 server was still crashing in v2.2.12 with some settings
- maildir: Various fixes and improvements to handling compressed mails,
especially when they have broken/missing S=sizes in filenames.
- fts-lucene, fts-solr: Fixed crash on search when the index contained
duplicate entries.
- Many fixes and performance improvements to dsync and replication
- director was somewhat broken when there were exactly two directors
in the ring. It caused errors about "weak users" getting stuck.
- mail_attachment_dir: Attachments with the last base64-encoded line
longer than the rest wasn't handled correctly.
- IMAP: SEARCH/SORT PARTIAL was handled completely wrong in v2.2.11+
- acl: Global ACL file handling was broken when multiple entries
matched the mailbox name. (Only the first entry was used.)On 05/08/2014 08:37 AM, Timo Sirainen wrote:

Sorry for replying to myself but now I'm able to show gdb backtrace with debugging symbols for dovecot 2.2.13 crash. See below.

There have been a ton of smaller and some larger changes since v2.2.12, so I thought I'd first make a RC release and the final v2.2.13 tomorrow. Please try it out!
Actually there were seven identical segfaults for the same user in three minutes:
Program terminated with signal 11, Segmentation fault. #0 0x00007f54dc1da4c5 in mail_cache_header_fields_read () from /usr/local/dovecot-2.2.13.rc1/lib/dovecot/libdovecot-storage.so.0
I thought this was fixed already, but I guess not. It would be helpful if you could either
a) Enable debug symbols so the backtrace would show exactly where it crashes
and/or
b) Send me the user's dovecot.index* files so I can try to reproduce the crash. (The .cache file may contain some cached headers and such, so might be problematic.) This probably isn't INBOX but some other folder that crashes.
Anyway, the problem is that the dovecot.index.cache file is somewhat broken. Deleting it will fix the crashes.
