samba - Sep 2014 - [Announce] CTDB release 2.5.4 is ready for download

This is the latest stable release of CTDB.  CTDB 2.5.4 can be used with
Samba releases 3.6.x, 4.0.x and 4.1.x.


Changes in CTDB 2.5.4
====================
User-visible changes
--------------------

* New command "ctdb detach" to detach a database.

* Support for TDB robust mutexes.  To enable set TDBMutexEnabled=1.
  The setting is per node.

* New manual page ctdb-statistics.7.

Important bug fixes
-------------------

* Verify policy routing configuration when starting up to make sure that
policy
  routing tables do not override default routing tables.

* "ctdb scriptstatus" should correctly list the number of scripts
executed.

* Do not run eventscripts at real-time priority.

* Make sure "ctdb restoredb" and "ctdb wipedb" cannot affect
an ongoing
  recovery.

* If a readonly record revokation fails, CTDB does not abort anymore.  It
will
  retry revoke.

* pending_calls statistic now gets updated correctly.

Important internal changes
--------------------------

* Vacuuming performance has been improved.

* Fix the order of setting recovery mode and freezing databases.

* Remove NAT gateway "monitor" event.

* Add per database queue for lock requests.  This improves the lock
  scheduling performance.

* When processing dmaster packets (DMASTER_REQUEST and DMASTER_REPLY) defer
all
  call processing for that record.  This avoids the temporary inconsistency
in
  dmaster information which causes rapid bouncing of call request between
two
  nodes.

* Correctly capture the output from lock helper processes, so it can be
logged.

* Many test improvements and additions.
