The ansible remote port should be None, not 22. Having a default value
of 22 means that '-o Port 22' will be appended to the ssh connection
all of the time. This is incorrect as when one would like to use
something like an ssh configuration file (-F) that sets the port to
something other than 22.
Part of this change requires that we check that, in get_config, the
value is not None before trying to cast it into an integer or float.
- 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
Using ANSIBLE_ROLE_PATH environment variable or role_path in ansible.cfg
can configure paths where roles will be searched for
extra paths will only be used as a backup once regular locations are exhausted
If a user supplies a string in the config (rather than an int), the code
should fix that- or blow up immediately- rather than allowing that value to
work it's way down and break w/in the connection object; when that happens,
the actual error is opaque and requires pdb.set_trace() to run down.
This shouldn't generally be needed unless you're working in an environment
that uses rediculously long FQDNs; if the name is too long, you wind up
hitting unix domain socket filepath limits enforced by ssh.
Still needs:
* chunked file transfer/receive
* should probably move all send/recv operations to separate
functions to reduce code duplication
* initial connection setup over ssh? or do we handle that in runner?
-c ssh is preferred in most cases if you have ControlPersist available, otherwise if you are comfortable you
can turn off recording while leaving host key checking on, etc.
ansible.constants was calling expanduser (by way of shell_expand_path)
on the entire configured value for the library and *_plugins
configuration values, but these values have always been interpreted as
multiple directories separated by os.pathsep. Thus, if you supplied
multiple directories for one of these values, typically only the first
(at least on *nix) would have e.g. "~" expanded to HOME.
Now PluginLoader does expansion on each individual path in each of
these variables.
