Most users of repo are also using Gerrit Code Review, and will want
the commit-msg hook to be automatically installed into their local
projects so that Change-Ids are assigned when commits are created,
not when they are first uploaded.

By running `repo manifest --uprade` an administrator can update the
current manifest format from the XML format to submodule format, but
we need all projects to be checked out in a work tree for this to
function correctly.

If a manifest top level directory contains '.gitmodules' we now
assume this is a git module format manifest and switch to using
that code, rather than the legacy XML based manifest.
At the same time, we move the bare repository for a project from
$TOP/.repo/projects/$REPO_PATH.git to be $REPO_NAME.git instead.
This makes it easier for us to later support a repo init from an
existing work tree, as we can more accurately predict the path of
the project's repository in the workspace. It also means that the
$TOP/.repo/projects/ directory is layed out like a mirror would be.

Some types of manifests might prefer to put their meta project work
tree under topdir, rather than inside of the .repo/ directory. We
can support that by allowing relpath to be optionally passed in.

If the manifest format changes during init or sync we need to do
a full reparse of the manifest, and possibly allow the new object
to reconfigure the local workspace to match its expectations.

The -o option permits the user to control the name of the manifest's
remote, which normally is hardcoded to be 'origin', but can differ
because we derive it at runtime from the configuration file.

If we don't clear the cache, there can be a timestamp race between
the pickle file and the raw text file, and we may not pick up the
edit when we create a new config object around the same path name.

If the manifest's work tree is actually inside of the rest of
the client work tree then its only fair that we include it as

This permits the XML style manifest to use 'default', while other

If the caller knows exactly what the manifest type must be we

I plan to have the new submodule manifest format use a different
layout for the m refs than the XML manifest format has used in
the past. Thus we need to move the behavior management into the
manifest object, and out of the project, so we can change it.

Users may wind up with a lot of loose object content in projects they
don't frequently make changes in, but that are modified by others.
Since we bypass many git code paths that would have otherwise called
out to `git gc --auto`, its possible for these projects to have
their loose object database grow out of control. To help prevent
that, we now invoke it ourselves during the network half of sync.

If the manifest is the newer SubmoduleManifest style, then the -m
option makes no sense, as you cannot select a specific file within
the current branch.

If the manifest isn't a single file format manifest, the -o option
makes no sense, as you cannot export multiple files to a single

If commands modify the git config too rapidly we might not notice
the .git/config file has been modified, as they could run in the
same filesystem timestamp window and thus not cause a change on
the config's mtime. This can cause repo to miss re-reading the
config file after running a command.
Allowing the cache to be flushed forces us to re-read the config.

If there are shell special characters in the editor string, we must
use /bin/sh to parse and execute it, rather than trying to rely on
a simple split(' '). This avoids vim starting up with two empty

When someone copies and pastes a setup line from a web page,
they might actually copy 'repo sync' onto the clipboard and wind
up pasting it into the "Your Name" prompt. This means they will
initialize their client with the user name of "repo sync", creating
some rather funny looking commits later on. For example:
To setup your source tree:
mkdir ~/code
cd ~/code
repo init -u git://....
repo sync
If this entire block was just blindly copy and pasted into the
terminal, the shell won't read "repo sync" but "repo init" will.
By showing the user their full identity string, and asking them
to confirm it before we continue, we can give the hapless user a
chance to recover from this mistake, without unfairly harming those
who were actually named 'repo' by their parents.

The --color flag wasn't introduced until git 1.6.3. Prior to that
version, `git grep --color` just produces a fatal error, as it is
an unsupported option. Since this is just pretty output and is not
critical to execution, we can simply omit the option if the version
of git we are running on doesn't support it.

If the pickle config file is 0 bytes in length, we may have

After a repo sync, some of the project paths might need
to be removed. This changes maintains a list of project
paths from the previous sync operation and compares.
The revisionExpr field now holds an expression from the manifest,
such as "refs/heads/master", while revisionId holds the current
commit-ish SHA-1 of the revisionExpr. Currently that is only
filled in if the manifest points directly to a SHA-1.
