Allow use of service module with just enable parameter, per issue #755.
Also fixed two other issues:
- fixed parameter to be 'enabled' per docs, not 'enable'.
- fixed if block that checks whether to run _do_enable() to check
whether the parameter is set, not the value of the enable value which
may be None or False. If enabled=no, the service would never be
disabled.
Convert git module to module magic.
Drop cruft no longer needed.
Standardize indent to 4 spaces in methods switchLocalBranch, reset,
clone, and get_version.
Update is_local_branch to also handle '* branch' format.
Add is_current branch method()
Update pull() method to use is_current_branch()
passwd -> password
loginpass -> login_password
loginuser -> login_user
loginhost -> login_host
Add an example playbook that shows how to use the modules.
These modules are based on the mysql_db and mysql_user modules.
Currently, the postgresql_user module can only grant all permissions
on a database, fine-grained access has not been implemented yet.
1. Passing the module to the various functions so that they can use module.fail_json and module.exit_json methods inside.
2. Because of point 1, install and remove methods do not return anything. Instead, they use the module functions itself.
3. Move the import statement (for apt and apt_pkg) inside main function so on import error, we can use module.fail_json to print the error.
This drops the branch option. The version option is overloaded
to mean either a sha1, branch, or tag. This also adds the option
'remote' which defaults to 'origin'.
clone() was simplified by removing the checkout operation. That
happens later when switch_version() is called.
Added the methods get_branches(), is_remote_branch(), and
is_local_branch(). get_branches() returns an array listing all
of the branches for the git repository. is_remote_branch() checks
whether the arguments supplied correspond to a remote branch.
Similarly, is_local_branch() checks for a local branch.
The pull() method now checks to see if it is on the desired branch.
If not, it checks out the requested branch and then does a pull.
This should keep issue #604 still fixed.
switch_version(), formerly switchver(), looks to see if it is
checking out a branch. If a branch, it checks it out with the --track
option. This type of checkout was in pull() before.
Updated pull, clone, and switch_version to return (rc, out, err).
