So instead of having:
group_vars/production.yml
A user could chose to reorganize to:
group_vars/production/staff.yml
group_vars/production/networks.yml
group_vars/production/dns.yml
(Backwards compatible.)
- Move all the supported YAML file extensions into a constant
- Use helper functions to avoid duplicate code for group/host vars
- Catch and disallow some confusing situations, such as the presence of
multiple group/host vars files for the same group/host, but with
different extensions. For example having both group_vars/all.yml and
group_vars/all.yaml.
- Catch and report file system permission issues, symlink errors,
unexpected file system objects
- Trivial performance improvement from making fewer stat system calls
- Restructuring that makes it easy for a following patch to support
directory recursion
Since ansible 1.2, it became possible to place a host_vars
directory in the same directory as a playbook, making it possible
to keep host_vars local to that playbook there. However, due to
python's os.path.dirname, a action such as:
$ ansible-playbook pb.yml
..would not pick up the host_vars as os.path.dirname("pb.yml")
returns "", unlike the unix command dirname that would return
".". Substituting "pb.yml" on the command line with "./pb.yml"
would do the trick, but is not always intuitive. This patch
solves the problem until python solves issue18547 [1].
[1] http://bugs.python.org/issue18547
Look for a file with the base name of the group/host, first without
a file extension, then with a '.yml' extension, and, finally, with
a '.yaml' extension, loading vars from only the first one found.
Hash variables are currently overriden if they are redefined. This
doesn't let the user refine hash entries or overriding selected keys,
which can, for some, be a desirable feature.
This patch let the user force hash merging by setting the
hash_behaviour value to "merge" (without the quotes) in ansible.cfg
However, by default, ansible behaves like it always did and if any value
besides "merge" is used ("replace" is suggested in the example ansible.cfg
file), it will also behave as always.
