Detect when on a 'no branch' branch. If so, checkout the HEAD branch
as reported by 'git remote show <remote>'. That should put the repo
back on a branch such that git can then merge changes as necessary.
In addition, removed hard-coded references to origin and replaced
with remote var.
git module used to check stderr for the string 'error' after calling
switch_version(). This changes that to just look at the return code to
determine whether the command failed. If the rc is not zero, the git
module will call fail_json().
The problem is that git checkout will summarize the commit message,
such as:
HEAD is now at ea38409... removing artificial error
When the string 'error' is the commit message, this check will
erroneously think the command failed.
This also removes the method switchLocalBranch() since it is no longer
used.
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()
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).
The ohai and facter modules use /usr/bin/logger to log the fact that
they have been invoked. I added 'import os' to the ping module
so that it could have the same syslog statements as the other modules.
I separated the condensed:
shlex.split(open(argfile, 'r').read())
into two separate statements similar to the other modules.
