We now correctly support re-initializing an existing client to point
to a different branch of the same manifest repository, effectively
allowing the client to switch the baseline it is operating on.

Simply setting repo.mirror true doesn't make a client into a mirror.
The on-disk layout is completely wrong for a mirror repository,
and until we fix our layout for a non-mirror client to more closely
resemble the upstream we can't do anything to easily turn on or
turn off the mirror status flag.

This has the same effect as saying "export REPO_TRACE=1" in

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
reasonable and helps Git to recognize the environment it is in.

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.

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.

REPO_PATH is the path relative the the root of the client.
REPO_REMOTE is the name of the remote system from the manifest.
REPO_LREV is the name of the revision from the manifest, but
translated to something the local repository knows.
REPO_RREV is the name of the revision from the manifest.
This allows us to do commands like:
repo forall -c 'echo "(cd $REPO_PATH && git checkout `git rev-parse HEAD`)"'
If a manifest specifies an invalid revision property, give the
user a better error message detaling the problem, instead of an
ugly Python traceback with a strange Git error message.

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.

There's an extra "," at the end of the line, which is causing
trouble when the manifest file specifies a revision for a

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.

This way users can add forks they know about to an existing project
that was already declared in the primary manifest. This is mostly
useful with the Linux kernel project, where multiple forks is quite
common for the main upstream tree (e.g. Linus' tree), a platform
architecture tree (e.g. ARM) and a device specific tree (e.g. the
msm7k tree used by Android).
Signed-off-by: Shawn O. Pearce <sop@google.com>
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.

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.

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 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.
