git-repo/subcmds/sync.py
Mike Frysinger ae6cb08ae5 split out cli validation from execution 
A common pattern in our subcommands is to verify the arguments &
options before executing things.  For some subcommands, that check
stage is quite long which makes the execution function even bigger.
Lets split that logic out of the execute phase so it's easier to
manage these.

This is most noticeable in the sync subcommand whose Execute func
is quite large, and the option checking makes up ~15% of it.

The manifest command's Execute can be simplified significantly as
the optparse configuration always sets output_file to a string.

helpDescription = """
The '%prog' command synchronizes local project directories
with the remote repositories specified in the manifest. If a local
project does not yet exist, it will clone a new local directory from
the remote repository and set up tracking branches as specified in
the manifest. If the local project already exists, '%prog'
will update the remote branches and rebase any new local changes
on top of the new remote changes.
'%prog' will synchronize all projects listed at the command
line. Projects can be specified either by name, or by a relative
or absolute path to the project's local directory. If no projects
are specified, '%prog' will synchronize all projects listed in
the manifest.
The -d/--detach option can be used to switch specified projects
back to the manifest revision. This option is especially helpful
if the project is currently on a topic branch, but the manifest
revision is temporarily needed.
The -s/--smart-sync option can be used to sync to a known good
build as specified by the manifest-server element in the current
manifest. The -t/--smart-tag option is similar and allows you to
specify a custom tag/label.
The -u/--manifest-server-username and -p/--manifest-server-password
options can be used to specify a username and password to authenticate
with the manifest server when using the -s or -t option.
If -u and -p are not specified when using the -s or -t option, '%prog'
will attempt to read authentication credentials for the manifest server
from the user's .netrc file.
'%prog' will not use authentication credentials from -u/-p or .netrc
if the manifest server specified in the manifest file already includes
credentials.
By default, all projects will be synced. The --fail-fast option can be used
to halt syncing as soon as possible when the the first project fails to sync.
The --force-sync option can be used to overwrite existing git
directories if they have previously been linked to a different
object direcotry. WARNING: This may cause data to be lost since
refs may be removed when overwriting.
The --force-remove-dirty option can be used to remove previously used
projects with uncommitted changes. WARNING: This may cause data to be
lost since uncommitted changes may be removed with projects that no longer
exist in the manifest.
The --no-clone-bundle option disables any attempt to use
$URL/clone.bundle to bootstrap a new Git repository from a
resumeable bundle file on a content delivery network. This
may be necessary if there are problems with the local Python
HTTP client or proxy configuration, but the Git binary works.
The --fetch-submodules option enables fetching Git submodules
of a project from server.
The -c/--current-branch option can be used to only fetch objects that
are on the branch specified by a project's revision.
The --optimized-fetch option can be used to only fetch projects that
are fixed to a sha1 revision if the sha1 revision does not already
exist locally.
The --prune option can be used to remove any refs that no longer
exist on the remote.
# SSH Connections
If at least one project remote URL uses an SSH connection (ssh://,
git+ssh://, or user@host:path syntax) repo will automatically
enable the SSH ControlMaster option when connecting to that host.
This feature permits other projects in the same '%prog' session to
reuse the same SSH tunnel, saving connection setup overheads.
To disable this behavior on UNIX platforms, set the GIT_SSH
environment variable to 'ssh'. For example:
export GIT_SSH=ssh
%prog
# Compatibility
This feature is automatically disabled on Windows, due to the lack
of UNIX domain socket support.
This feature is not compatible with url.insteadof rewrites in the
user's ~/.gitconfig. '%prog' is currently not able to perform the
rewrite early enough to establish the ControlMaster tunnel.
If the remote SSH daemon is Gerrit Code Review, version 2.0.10 or
later is required to fix a server side protocol bug.
