NEWS

v2.2.26.0 2016-10-28  Timo Sirainen <tss at iki.fi>

- Fixed some compiling issues.
- auth: Fixed assert-crash when using NTLM or SKEY mechanisms and
  multiple passdbs.
- auth: Fixed crash when exporting to auth-worker passdb extra fields
  that had empty values.
- dsync: Fixed assert-crash in dsync_brain_sync_mailbox_deinit

v2.2.26 2016-10-27  Timo Sirainen <tss at iki.fi>

* master: Removed hardcoded 511 backlog limit for listen(). The kernel
  should limit this as needed.
* doveadm import: Source user is now initialized the same as target
  user. Added -U parameter to override the source user.
* Mailbox names are no longer limited to 16 hierarchy levels. We'll
  check another way to make sure mailbox names can't grow larger than
  4096 bytes.

+ Added a concept of "alternative usernames" by returning user_* extra
  field(s) in passdb. doveadm proxy list shows these alt usernames in
  "doveadm proxy list" output. "doveadm director&proxy kick" adds
  -f <passdb field> parameter. The alt usernames don't have to be
  unique, so this allows creation of user groups and kicking them in
  one command.
+ auth: passdb/userdb dict allows now %variables in key settings.
+ auth: If passdb returns noauthenticate=yes extra field, assume that
  it only set extra fields and authentication wasn't actually performed.
+ auth: passdb static now supports password={scheme} prefix.
+ auth, login_log_format_elements: Added %{local_name} variable, which
  expands to TLS SNI hostname if given.
+ imapc: Added imapc_max_line_length to limit maximum memory usage.
+ imap, pop3: Added rawlog_dir setting to store IMAP/POP3 traffic logs.
  This replaces at least partially the rawlog plugin.
+ dsync: Added dsync_features=empty-header-workaround setting. This
  makes incremental dsyncs work better for servers that randomly return
  empty headers for mails. When an empty header is seen for an existing
  mail, dsync assumes that it matches the local mail.
+ doveadm sync/backup: Added -I <max size> parameter to skip too
  large mails.
+ doveadm sync/backup: Fixed -t parameter and added -e for "end date".
+ doveadm mailbox metadata: Added -s parameter to allow accessing
  server metadata by using empty mailbox name.
+ Added "doveadm service status" and "doveadm process status" commands.
+ director: Added director_flush_socket. See
  http://wiki2.dovecot.org/Director#Flush_socket
+ doveadm director flush: Users are now moved only max 100 at a time to
  avoid load spikes. --max-parallel parameter overrides this.
+ Added FILE_LOCK_SLOW_WARNING_MSECS environment, which logs a warning
  if any lock is waited on or kept for this many milliseconds.

- master process's listener socket was leaked to all child processes.
  This might have allowed untrusted processes to capture and prevent
  "doveadm service stop" comands from working.
- login proxy: Fixed crash when outgoing SSL connections were hanging.
- auth: userdb fields weren't passed to auth-workers, so %{userdb:*}
  from previous userdbs didn't work there.
- auth: Each userdb lookup from cache reset its TTL.
- auth: Fixed auth_bind=yes + sasl_bind=yes to work together
- auth: Blocking userdb lookups reset extra fields set by previous
  userdbs.
- auth: Cache keys didn't include %{passdb:*} and %{userdb:*}
- auth-policy: Fixed crash due to using already-freed memory if policy
  lookup takes longer than auth request exists.
- lib-auth: Unescape passdb/userdb extra fields. Mainly affected
  returning extra fields with LFs or TABs.
- lmtp_user_concurrency_limit>0 setting was logging unnecessary
  anvil errors.
- lmtp_user_concurrency_limit is now checked before quota check with
  lmtp_rcpt_check_quota=yes to avoid unnecessary quota work.
- lmtp: %{userdb:*} variables didn't work in mail_log_prefix
- autoexpunge settings for mailboxes with wildcards didn't work when
  namespace prefix was non-empty.
- Fixed writing >2GB to iostream-temp files (used by fs-compress,
  fs-metawrap, doveadm-http)
- director: Ignore duplicates in director_servers setting.
- director: Many fixes related to connection handshaking, user moving
  and error handling.
- director: Don't break with shutdown_clients=no
- zlib, IMAP BINARY: Fixed internal caching when accessing multiple
  newly created mails. They all had UID=0 and the next mail could have
  wrongly used the previously cached mail.
- doveadm stats reset wasn't reseting all the stats.
- auth_stats=yes: Don't update num_logins, since it doubles them when
  using with mail stats.
- quota count: Fixed deadlocks when updating vsize header.
- dict-quota: Fixed crashes happening due to memory corruption.
- dict proxy: Fixed various timeout-related bugs.
- doveadm proxying: Fixed -A and -u wildcard handling.
- doveadm proxying: Fixed hangs and bugs related to printing.
- imap: Fixed wrongly triggering assert-crash in
  client_check_command_hangs.
- imap proxy: Don't send ID command pipelined with nopipelining=yes
- imap-hibernate: Don't execute quota_over_script or last_login after
  un-hibernation.
- imap-hibernate: Don't un-hibernate if client sends DONE+IDLE in one
  IP packet.
- imap-hibernate: Fixed various failures when un-hibernating.
- fts: fts_autoindex=yes was broken in 2.2.25 unless
  fts_autoindex_exclude settings existed.
- fts-solr: Fixed searching multiple mailboxes (patch by x16a0)
- doveadm fetch body.snippet wasn't working in 2.2.25. Also fixed a
  crash with certain emails.
- pop3-migration + dbox: Various fixes related to POP3 UIDL
  optimization in 2.2.25.
- pop3-migration: Fixed "truncated email header" workaround.
