Salt 0.10.0 Release Notes
|
|
=========================
|
|
|
|
:release: 2012-06-16
|
|
|
|
0.10.0 has arrived! This release comes with MANY bug fixes, and new
|
|
capabilities which greatly enhance performance and reliability. This
|
|
release is primarily a bug fix release with many new tests and many repaired
|
|
bugs. This release also introduces a few new key features which were brought
|
|
in primarily to repair bugs and some limitations found in some of the
|
|
components of the original architecture.
|
|
|
|
Major Features
|
|
==============
|
|
|
|
Event System
|
|
------------
|
|
|
|
The Salt Master now comes equipped with a new event system. This event system
|
|
has replaced some of the back end of the Salt client and offers the beginning of
|
|
a system which will make plugging external applications into Salt. The event
|
|
system relies on a local ZeroMQ publish socket and other processes can connect
|
|
to this socket and listen for events. The new events can be easily managed via
|
|
Salt's event library.
|
|
|
|
Unprivileged User Updates
|
|
-------------------------
|
|
|
|
Some enhancements have been added to Salt for running as a user other than
|
|
root. These new additions should make switching the user that the Salt Master
|
|
is running as very painless, simply change the ``user`` option in the master
|
|
configuration and restart the master, Salt will take care of all of the
|
|
particulars for you.
|
|
|
|
Peer Runner Execution
|
|
---------------------
|
|
|
|
Salt has long had the peer communication system used to allow minions to send
|
|
commands via the salt master. 0.10.0 adds a new capability here, now the
|
|
master can be configured to allow for minions to execute Salt runners via
|
|
the ``peer_run`` option in the salt master configuration.
|
|
|
|
YAML Parsing Updates
|
|
--------------------
|
|
|
|
In the past the YAML parser for sls files would return the incorrect numbers
|
|
when the file mode was set with a preceding 0. The YAML parser used in Salt
|
|
has been modified to no longer convert these number into octal but to keep
|
|
them as the correct value so that sls files can be a little cleaner to write.
|
|
|
|
State Call Data Files
|
|
=====================
|
|
|
|
It was requested that the minion keep a local cache of the most recent executed
|
|
state run. This has been added and now with state runs the data is stored in a
|
|
msgpack file in the minion's cachedir.
|
|
|
|
Turning Off the Job Cache
|
|
=========================
|
|
|
|
A new option has been added to the master configuration file. In previous
|
|
releases the Salt client would look over the Salt job cache to read in
|
|
the minion return data. With the addition of the event system the Salt client
|
|
can now watch for events directly from the master worker processes.
|
|
|
|
This means that the job cache is no longer a hard requirement. Keep in mind
|
|
though, that turning off the job cache means that historic job execution data
|
|
cannot be retrieved.
|
|
|
|
Test Updates
|
|
============
|
|
|
|
Minion Swarms Are Faster
|
|
------------------------
|
|
|
|
To continue our efforts with testing Salt's ability to scale the minionswarm
|
|
script has been updated. The minionswarm can now start up minions much faster
|
|
than it could before and comes with a new feature allowing modules to be
|
|
disabled, thus lowering the minion's footprint when making a swarm. These new
|
|
updates have allows us to test
|
|
|
|
.. code-block:: bash
|
|
|
|
# python minionswarm.py -m 20 --master salt-master
|
|
|
|
|
|
Many Fixes
|

|
|

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

|
|
stability. |
