By setting a project-name on a remote nested within a project forks
of a project like the Linux kernel can be easily handled by fetching
all relevant forks into the same client side project under different
remote names. Developers can create branches off different remotes
using `git checkout --track -b $myname $remote/$branch` and later
`repo upload` automatically redirects to the proper fork project
in the code review server.

This way "forks" of a project, e.g. the linux kernel, can be setup to
use different destination projects in the review server by creating
different remotes in the client side Git repository.

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.

Whatever branch name we checked the manifest out from is the name
we want to reflect throughout the rest of the projects, e.g. within
the special "m/" remote space.
This reduces the difference between different branches within the
manifest file.

Prior to open-sourcing repo we had manifests in two different
layouts; one where the manifest was a straight-up git clone, and
one where the manifest was our bare repository with symlink work
tree format (identical to what our projects use). Only the latter
form is created or used by repo at this point, so the transition
code to handle the straight-up git clone is not necessary.

This destroys a local development branch, removing all history
of that branch from ever existing. If the branch is currently
checked out we move back to the upstream revision.

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.

Some users have noticed that repo doesn't work on VFAT, as we
require a POSIX filesystem with POSIX symlink support. Catching the
OSError during our symlink creation and raising a GitError with a
more descriptive message will help users to troubleshoot and fix
their own installation problems.

If we are already up-to-date we just want to display no output.
This means we have to avoid calling "git merge" if there aren't
commits to be merged into the working directory.

Instead of trying to rebase the changes on a topic branch that
has been fully merged into the upstream branch we track, we should
just fast-forward the topic branch to the new upstream revision.
This way the branch doesn't try to rewrite commits that are already
merged in the upstream.

Now that repo relies only on the git data stream (as it is much
faster to download through) we don't really need to be parsing the
<snapshot> elements within manifest. Its a lot of complex code to
convert the tar (or zip) through to a fast import stream, and we
just aren't calling it anymore.

Git may have been installed without its hooks directory, which
means we won't have any hooks in a repo created git repository.
Since we are just deleting the hooks it doesn't matter.

Downloading and streaming a tar into Git is slower than just
letting the native git:// protocol handle the data transfer,
especially when there are multiple revisions available and
Git can perform delta compression across revisions.

Hiding error messages from the remote peer is not a good idea,
as users should be made aware when the remote peer is not a
complete Git repository so they can alert the administrators
and have the repository corrected.

The initial open source release of the Android 1.0 platform had
some problems with its Perforce->Git imports. Google was forced
to rewrite some history to redirect users onto more stable upstream
sources and correct errors in the imports.
Not everyone has the correct android-1.0 tags, as some users did
manage to fetch the platform early, before the mirror sites crashed
and the history was rewritten.
This change is a band-aid to ensure any stale android-1.0 tags are
get updated to the corrected version. It should be backed out at
some point in the near future, when we can be fairly certain that
everyone has the correct android-1.0 tags.

By creating a .repo/local_manifest.xml the user can add extra
projects into their client space, without touching the main
manifest script.
For example:
$ cat .repo/local_manifest.xml
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project path="android-build"
name="platform/build"
remote="korg"
revision="android-1.0" />
</manifest>

Now `repo download . 1402` would download the change numbered 1402
into the current project and check it out for the user, using a
detached HEAD. `repo sync .` would back out of the change and
return to the upstream version.
Multiple projects can be fetched at once by listing them out on
the command line as different arguments.
Individual patch sets can be selected by adding a '/n' to indicate
the n-th patch set should be downloaded instead of the default of
patch set 1.

Hosted domain account (such as "@google.com" itself) don't work on the
Google App Engine service unless the user specifically creates their
own Google Account (https://www.google.com/accounts/NewAccount) with
the same email address.
When both such accounts exist we must *only* use the Google Account in
our auth request, as that is all Google App Engine will honor when we
send it the session cookie.
However, Google has internal servers that may also be running Gerrit
based applications. In those case we must use the hosted auth login
for @google.com user accounts, as the internal servers honor only the
hosted account and not the public Google Account database.
In the future we may need to add other domains to the "HOSTED" list
if other Gerrit instances are setup on hosted domains and locked to
only those domain's user accounts, similar to how a server that is
internal to Google would be setup. Since this is currently not a
likely occurrence I'm not worrying about making it configurable at
this juncture.

If the reflog for the upstream branch has only 1 entry in it, as
the branch has been updated only once, we can get back the 0{40}
object id from `git rev-parse upstream@{1}`, in which case we should
consider it to be the same as if upstream@{1} is not defined.
