The Facts class and subclasses no longer take a dict argument for
instantiation. populate() now returns self.facts.
Other changes:
- Facts.__init__() takes over most of the work from populate() so that
subclasses can benefit from its knowledge.
- Drop setting unknown facts to 'NA' in __init__() in various
subclasses.
- Check for presence of facts in get_virtual_facts()
- Update ansible_facts() to use facts.update(<classname>().populate())
This changes and organizes facts into a base class Facts and several
sub classes that implement the necessary functionality. The classes
are:
- Facts: base class. Implements basic facts that should be common to a
number of platforms. It is also where SSH keys and SELinux facts are
set.
- Hardware: A subclass of Facts that should be further
subclassed per platform for CPU, memory, and related facts.
- LinuxHardware: subclass of Hardware for Linux platforms
- SunOSHardware: subclass of Hardware for SunOS platforms
- FreeBSDHardware: subclass of Hardware for FreeBSD
- Network: A subclass of Facts that that should be further
subclassed per platform for IP, both IPv4 and IPv6, information.
- LinuxNetwork: Currently only implementation for determining network
facts.
- Virtual: A subclass of Facts that that should be further
subclassed per platform to determine virtual environment facts.
- LinuxVirtual: Currently only implementation for determining virtual
facts.
If facts are needed for additional platforms, one of the above classes
(eg Network) can be further subclassed and implement the necessary
functionality.
In addition, it fixes get_network_facts() to work on Fedora17. That
broke due to changes to ifconfig output.
should be a huge reduction of total ansible source, at a slight cost of difficulty in original module development.
We need to apply this now to all modules, but may need to have some exemptions to things like command, which should
subclass this module.
The service module was printing stuff to stderr, returning two
JSON dicts, not using consistent 'failed' values, had dead code
and unused variables. Added detection for the case when service
status returns 'xxx is dead and pid file exists' and made the
code a bit easier to read.
(Also a fix for the user module error handling when the user
is not present at the time of the return. This can only really be caused by multiple ansible executions).
Takes a lot of the fixes to the user module and applies them to the
group module: provide stdout/stderr in result if available and call
fail_json() if the attempted action fails.
The user module now returns the output, both stdout and stderr, from
useradd, usermod, and userdel. This should help debug cases why one of
those commands fail. In addition, the user module will now call
fail_json() when the attempted command failed so as to properly
communicate a failure in a playbook.
This flag will show playbook output from non-failing commands. -v is also added to /usr/bin/ansible, but not yet used.
I also gutted some internals code dealing with 'invocations' which allowed the callback to know what module invoked
it. This is not something 0.5 does or needed, so callbacks have been simplified.
