There is also shortcuts in case if the "current branch" is
a persistent revision such as tag or sha1. We check if the
persistent revision is present locally and if it does - do
no fetch anything from the server.
This greately reduces sync time and size of the on-disk repo

This permits manifest authors to suggest a number of parallel
fetch operations against a remote server. For example, Gerrit
Code Review servers support queuing of requests and processes
them in first-in, first-out order. Running concurrent fetches
can utilize multiple CPUs on the Gerrit server, but will also
decrease overall operation latency by having the request put
into the queue ready to execute as soon as a CPU is free.

Each worker thread requires at least 3 file descriptors to run the
forked 'git fetch' child to operate against the local repository.
Mac OS X has the RLIMIT_NOFILE set to 256 by default, which means
a sync -j128 often fails when the workers run out of pipes within
the Python parent process.

This is an evolution of 'smart-sync' that adds a new option, -t,
that allows you to specify a tag/label to use instead of the
"latest good build" on the current manifest branch which -s does.

The bug that this is fixing is described here:
http://code.google.com/p/chromium-os/issues/detail?id=6813
This fix allows the helper threads to signal the main thread that they
saw an error. When the main thread sees the error, it will let all
existing threads finish, then exit with an error.

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.

This feature is used to convey information on a when a branch has
ceased development or if it is an experimental branch with a few
gotchas, etc.
You add it to your manifest XML by doing something like this:
<manifest>
<notice>
NOTE TO DEVELOPERS:
If you checkin code, you have to pinky-swear that it contains no bugs.
Anyone who breaks their promise will have tomatoes thrown at them in the
team meeting. Be sure to bring an extra set of clothes.
</notice>
<remote ... />
...
</manifest>
Carriage returns and indentation are relevant for the text in this tag.
This feature was requested by Anush Elangovan on the ChromiumOS team.
This adds a new flag -f/--force-broken that will allow the rest of
the sync process to continue instead of bailing when a particular
project fails to sync.

This patch does two things for being compatibile with
those Python which are built without threading support:
1. As the Python document and Shawn suggested, import dummy_threading
when the threading is not available.
2. Reserve the single threaded code and make it default.
In cases the --jobs does not work properly with dummy_threading,
we still have a safe fallback.

This option allows the user to specify a manifest server to use when
syncing. This manifest server will provide a manifest pegging each
project to a known green build. This allows developers to work on a
known good tree that is known to build and pass tests, preventing
failed builds to hamper productivity.
The manifest used is not "sticky" so as to allow subsequent
'repo sync' calls to sync to the tip of the tree.

This bug happens when a project gets added to the manifest, and
then is renamed. Users who happened to have run "repo sync" after
the project was added but before the rename happened will try to
read the data from the old project, as the manifest was only updated
after all projects were updated successfully.
If a line is blank in project.list, its not a relevant project path,
so skip over it. Existing project.list files may have blank lines if
sync was run with no projects at all, and the file was created empty.

We have no working tree, so we cannot update the project.list
state file, nor should we try to delete a directory if a project is
removed from the manifest. Clients would still need the repository
for historical records.

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.

Its unlikely that a new version of repo will be delivered in any
given day, so we now check only once every 24 hours to see if repo
has been updated. This reduces the sync cost, as we no longer need
to contact the repo distribution servers every time we do a sync.
repo selfupdate can still be used to force a check.

We now try to sync all projects that can be done safely first, before
we start rebasing user commits over the upstream. This has the nice
effect of making the local tree as close to the upstream as possible
before the user has to start resolving merge conflicts, as that extra
information in other projects may aid in the conflict resolution.
Informational output is buffered and delayed until calculation for
all projects has been done, so that the user gets one concise list
of notice messages, rather than it interrupting the progress meter.
Fast-forward output is now prefixed with the project header, so the
user can see which project that update is taking place in, and make
some relation of the diffstat back to the project name.
Rebase output is now prefixed with the project header, so that if
the rebase fails, the user can see which project we were operating
on and can try to address the failure themselves.
Since rebase sits on a detached HEAD, we now look for an in-progress
rebase during sync, so we can alert the user that the given project
is in a state we cannot handle.

This permits usage of 'repo sync' while offline, as we bypass the
network based portions of the code and do only the local sync.

The -d flag moves the project back to a detached HEAD state,
matching what is listed in the manifest. This can be useful to
set a client to something stable (or at least well-known), such as
before a sequence of 'repo download' commands are used to get some
changes for testing.

If a client was created with "repo init --mirror" then there are
no working directories present, and no files checked out. Using
a command like "repo status" in this context makes no sense, and
actually throws back a Pytyon traceback at the console when the
underlying commands fail out.
We now tag commands with the MirrorSafeCommand type if they are
able to be executed within a mirror directory safely. Using a
command in a mirror which lacks this base class results in a
useful error letting you know the command isn't supported.

The mirror option downloads a complete forrest (as described by the
manifest) and creates a replica of the remote repositories rather
than a client working directory. This permits other clients to
sync off the mirror site.
A mirror can be positioned in a "DMZ", where the mirror executes
"repo sync" to obtain changes from the external upstream and
clients inside the protected zone operate off the mirror only,
and therefore do not require direct git:// access to the external
upstream repositories.

This hook is evaluated by `git gc --auto` to determine if it is a
good idea to execute a GC at this time, or defer it to some later
date. When working on a laptop its a good idea to avoid GC if you
are on battery power as the extra CPU and disk IO would consume a
decent amount of the charge.
The hook is the standard sample hook from git.git contrib/hooks,
last modified in git.git by 84ed4c5d117d72f02cc918e413b9861a9d2846d7.
I added the GPLv2 header to the script to ensure the license notice
is clear, as it does not match repo's own APLv2 license.
We only update hooks during initial repository creation or on
a repo sync. This way we don't incur huge overheads from the
hook stat operations during "repo status" or even the normal
"repo sync" cases.
