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 `repo start foo` fails due to uncommitted and unmergeable changes
in a single project, we have switched half of the projects over to
the new target branches, but didn't on the one that failed to move.
This change improves the situation by doing three things differently:
- We keep going when we encounter an error, so other projects
that can successfully switch still switch.
- We ignore projects whose current branch is already on the
requested name; they are logically already setup.
- We checkout the branch if it already exists, rather than
trying to recreate the branch.

This can be useful to create a new manifest from an existing client,
especially if the client wants to use the "-r" option to set each
project's revision to the current commit SHA-1, making a sort of a
tag file that can be used to recreate this exact state elsewhere.

When creating a mirror repository we will always be using a bare
repository. Setting $GIT_DIR/config to have core.bare = true is

Months ago when the Android Open Source Project launched we had some
import errors that had to be fixed and worked over. These hacks
were here to help users update their clients to newer versions of
the imported code.
Its very likely all clients have either been deleted, or have been
updated and have the fixed imports. So we don't need this hack in
repo anymore.
If a very ancient client still existed, it would need to be created
from scratch anyway, due to the Android cupcake branch merging
into master and the manifest changes not being able to be handled
correctly by repo. A new client wouldn't have the incorrectly
imported code in it, and thus wouldn't need this hack.

Prior to git 1.6.1-rc3~5 the output of 'git branch -d' matched:
Deleted branch (.*)\.
where the subgroup grabbed the branch name. In v1.6.1-rc3~5 (aka
a126ed0a01e265d7f3b2972a34e85636e12e6d34) Brandon Casey changed
the output to include the SHA-1 of the branch name, now matching
the pattern:
Deleted branch (.*) \([0-9a-f]*\)\.
Instead of parsing the output of git branch we now re-obtain the
list of branches after the deletion attempt and perform a set
difference in memory to determine which branches we were able to
successfully delete.

In Gerrit2 uploads are sent over "git push ssh://...", as this

There's an extra "," at the end of the line, which is causing
trouble when the manifest file specifies a revision for a
project. Since the default manifest file doesn't specify
revisions for the projects, the problem has gone unnoticed.

issue and providing a patch.

Users are prompted with the list of known changes we are about
to upload, and they can fill out the current change numbers for
any changes which already exist in the data store. For each of
those changes the change number and commit id is sent as part of
the upload request, so Gerrit can insert the new commit as a new
patch set of the existing change, rather than make a new change.
This facility permits developers to replace a patch so they can
address comments made on a prior version of the same change.

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

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.

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.

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.
