Salt 0.10.2 Release Notes
=========================

:release: 2012-07-30

0.10.2 is out! This release comes with enhancements to the pillar interface,
cleaner ways to access the salt-call capabilities in the API, minion data
caching and the event system has been added to salt minions.

There have also been updates to the ZeroMQ functions, many more tests
(thanks to sponsors, the code sprint and many contributors) and a swath
of bug fixes.

Major Features
==============

Ext Pillar Modules
------------------

The ranks of available Salt modules directories sees a new member in 0.10.2.
With the popularity of pillar a higher demand has arisen for ``ext_pillar``
interfaces to be more like regular Salt module additions. Now ext_pillar
interfaces can be added in the same way as other modules, just drop it into
the pillar directory in the salt source.

Minion Events
-------------

In 0.10.0 an event system was added to the Salt master. 0.10.2 adds the event
system to the minions as well. Now event can be published on a local minion
as well.

The minions can also send events back up to the master. This means that Salt is
able to communicate individual events from the minions back up to the Master
which are not associated with command.

Minion Data Caching
-------------------

When pillar was introduced the landscape for available data was greatly
enhanced. The minion's began sending grain data back to the master on a
regular basis.

The new config option on the master called ``minion_data_cache`` instructs the
Salt master to maintain a cache of the minion's grains and pillar data in the
cachedir. This option is turned off by default to avoid hitting the disk more,
but when enabled the cache is used to make grain matching from the salt command
more powerful, since the minions that will match can be predetermined.

Backup Files
------------

By default all files replaced by the file.managed and file.recurse states we
simply deleted. 0.10.2 adds a new option. By setting the backup option to
``minion`` the files are backed up before they are replaced.

The backed up files are located in the cachedir under the file_backup
directory. On a default system this will be at:
``/var/cache/salt/file_backup``

Configuration files
-------------------

``salt-master`` and ``salt-minion`` automatically load additional configuration
files from ``master.d/*.conf`` respective ``minion.d/*.conf`` where
``master.d``/``minion.d`` is a directory in the same directory as the main
configuration file.

Salt Key Verification
---------------------

A number of users complained that they had inadvertently deleted the wrong salt
authentication keys. 0.10.2 now displays what keys are going to be deleted
and verifies that they are the keys that are intended for deletion.

Key auto-signing
----------------

If ``autosign_file`` is specified in the configuration file incoming keys
will be compared to the list of keynames in ``autosign_file``. Regular
expressions as well as globbing is supported.

The file must only be writable by the user otherwise the file will be
ignored. To relax the permission and allow group write access set the
``permissive_pki_access`` option.

Module changes
--------------

Improved OpenBSD support
^^^^^^^^^^^^^^^^^^^^^^^^

New modules for managing services and packages were provided by Joshua
Elsasser to further improve the support for OpenBSD.

Existing modules like the `disk` module were also improved to support
OpenBSD.


SQL Modules
^^^^^^^^^^^

The MySQL and PostgreSQL modules have both received a number of additions thanks
to the work of Avi Marcus and Roman Imankulov.

ZFS Support on FreeBSD
^^^^^^^^^^^^^^^^^^^^^^

A new ZFS module has been added by Kurtis Velarde for FreeBSD supporting
various ZFS operations like creating, extending or removing zpools.


Augeas
^^^^^^

A new Augeas module by Ulrich Dangel for editing and verifying config files.

Native Debian Service module
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The support for the Debian was further improved with an new service module
for Debian by Ahmad Khayyat supporting `disable` and `enable`.


Cassandra
^^^^^^^^^

Cassandra support has been added by Adam Garside. Currently only
status and diagnostic information are supported.

Networking
^^^^^^^^^^

The networking support for `RHEL` has been improved and supports bonding
support as well as zeroconf configuration.


Monit
^^^^^

Basic monit support by Kurtis Velarde to control services via monit.

nzbget
^^^^^^

Basic support for controlling nzbget by Joseph Hall

Bluetooth
^^^^^^^^^

Baisc ``bluez`` support for managing and controlling Bluetooth devices.
Supports scanning as well as pairing/unpairing by Joseph Hall.

Test Updates
============

Consistency Testing
-------------------

Another testing script has been added. A bug was found in pillar when many
minions generated pillar data at the same time. The new ``consist.py`` script
is the tests directory was created to reproduce bugs where data should always
be consistent.

Many Fixes
==========

To get a good idea for the number of bugfixes this release offers take a look
at the closed tickets for 0.10.2, this is a very substantial update:

Master and Minion Stability Fixes
---------------------------------

As Salt deployments grow new ways to break Salt are discovered. 0.10.2 comes
with a number of fixes for the minions and master greatly improving Salt
stability.
