dovecot-2.2.32

[bdubbs@…]

New point version.

[Pierre Labastie]

v2.2.32 2017-08-24  Timo Sirainen <tss@iki.fi>

	* imapc: Info-level line is logged every time when successfully
	  connected to the remote server. This includes local/remote IP/port,
	  which can be useful for matching against external logs.
	* config: Log a warning if plugin { key=no } is used explicitly.
	  v2.3 will support "no" properly in plugin settings, but for now
	  any value at all for a boolean plugin setting is treated as "yes",
	  even if it's written as explicit "no". This change will now warn
	  that it most likely won't work as intended.

	+ Various optimizations to avoid accessing files/directories when it's
	  not necessary. Especially avoid accessing mail root directories when
	  INDEX directories point to a different filesystem.
	+ mail_location can now include ITERINDEX parameter. This tells Dovecot
	  to perform mailbox listing from the INDEX path instead of from the
	  mail root path. It's mainly useful when the INDEX storage is on a
	  faster storage.
	+ mail_location can now include VOLATILEDIR=<path> parameter. This
	  is used for creating lock files and in future potentially other
	  files that don't need to exist permanently. The path could point to
	  tmpfs for example. This is especially useful to avoid creating lock
	  files to NFS or other remote filesystems. For example:
	  mail_location=sdbox:~/sdbox:VOLATILEDIR=/tmp/volatile/%2.256Nu/%u
	+ mail_location's LISTINDEX=<path> can now contain a full path.
	  This allows storing mailbox list index to a different storage
	  than the rest of the indexes, for example to tmpfs.
	+ mail_location can now include NO-NOSELECT parameter. This
	  automatically deletes any \NoSelect mailboxes that have no children.
	  These mailboxes are sometimes confusing to users.
	+ mail_location can now include BROKENCHAR=<char> parameter. This can
	  be useful with imapc to access mailbox names that aren't valid mUTF-7
	  charset from remote servers.
	+ If mailbox_list_index_very_dirty_syncs=yes, the list index is no
	  longer refreshed against filesystem when listing mailboxes. This
	  allows the mailbox listing to be done entirely by only reading the
	  mailbox list index.
	+ Added mailbox_list_index_include_inbox setting to control whether
	  INBOX's STATUS information should be cached in the mailbox list
	  index. The default is "no", but it may be useful to change it to
	  "yes", especially if LISTINDEX points to tmpfs.
	+ userdb can return chdir=<path>, which override mail_home for the
	  chdir location. This can be useful to avoid accessing home directory
	  on login.
	+ userdb can return postlogin=<socket> to specify per-user imap/pop3
	  postlogin socket path.
	+ cassandra: Add support for result paging by adding page_size=<n>
	  parameter to the connect setting.
	+ dsync/imapc, pop3-migration plugin: Strip also trailing tabs from
	  headers when matching mails. This helps with migrations from Zimbra.
	+ imap_logout_format supports now %{appended} and %{autoexpunged}
	+ virtual plugin: Optimize IDLE to use mailbox list index for finding
	  out when something has changed.
	+ Added apparmor plugin. See https://wiki2.dovecot.org/Plugins/Apparmor
	- virtual plugin: A lot of fixes. In many cases it was also working
	  very inefficiently or even incorrectly.
	- imap: NOTIFY parameter parsing was incorrectly "fixed" in v2.2.31.
	  It was actually (mostly) working in previous versions, but broken
	  in v2.2.31.
	- Modseq tracking didn't always work correctly. This could have caused
	  imap unhibernation to fail or IMAP QRESYNC/CONDSTORE extensions to
	  not work perfectly.
	- mdbox: "Inconsistency in map index" wasn't fixed automatically
	- dict-ldap: %variable values used in the LDAP filter weren't escaped.
	- quota=count: quota_warning = -storage=.. was never executed (try #2).
	  v2.2.31 fixed it for -messages, but not for -storage.
	- imapc: >= 32 kB mail bodies were supposed to be cached for subsequent
	  FETCHes, but weren't.
	- quota-status service didn't support recipient_delimiter
	- acl: Don't access dovecot-acl-list files with acl_globals_only=yes
	- mail_location: If INDEX dir is set, mailbox deletion deletes its
	  childrens' indexes. For example if "box" is deleted, "box/child"
	  index directory was deleted as well (but mails were preserved).
	- director: v2.2.31 caused rapid reconnection loops to directors
	  that were down.

I have a problem with tests:

Amazingly, no test is said to fail (that is, all lines "read 0/xxx test failed") If I do not find soon what causes this (libtirpc?), I'll move to 8.2

OK: it seems it is a bug in valgrind. See ​https://bugzilla.redhat.com/show_bug.cgi?id=1462258. And there was the same error with 2.2.31 too. I'll update with a note that one test may report an error if valgrind is used.
