"UnboundLocalError: local variable 'branch' referenced before assignment" is
raised in git, line 282, in switch_version.
Exception is raised when version is not branch and version checkout fails.
E.g. when version is nonexistant commit.
Git is unable to checkout the specified `version` when the repository is
cloned with a reduced history (`depth`). However, if the repository is
already cloned, subsequent git module calls will update the repository
(default update=True), then properly checkout the specified `version`.
To allow the initial call to properly clone the specified `version`, at
the specified `depth`, this patch adds the `--branch` parameter when
cloning the repository.
This does two things:
* add --recursive option to git clone command in clone(). This will
initialize all submodules when cloning a remote repository.
* Add submodule_update() and call that from fetch(). submodule_update()
calls two git commands iff the file .gitmodules exists in the
repository:
* 'git submodule sync' - synchronizes the submodules' remote URL
configuration setting to the value in .gitmodules.
* 'git submodule update --init --recursive' - initialize and update
registered submodules to the commit specified in the index of the
containing repository.
If a repository was cloned without --recursive, submodule_update() will
ensure that the submodules are initialized and updated.
Migrated all examples: in DOCUMENTATION=''' string to standalone EXAMPLES=''' string
Added deprecation warning to moduledev.rst and remove deprecated example from it
Fixed up a few typos and uppercased some acronyms.
add consistency to how EXAMPLES are formatted
This will allow just making sure the repo exists w/out actually making
any chnages to it. Useful if you're going to run a play repeatedly
against a host that might have active development going on in the
repository (think initial bootstrap of a developers system, and
continued playbook runs to work on other projects).
