Do not update the .merge in case if revision is SHA.

This new attribute can prevent 'repo sync' from automatically rebasing.
I hit a situation in where one of the git repositories I was tracking
was actually an external repository that I wanted to pull commits
into and merge myself. (NOT rebase, since that would lose the merge
history.) In this case, I'm not using 'repo upload', I'm manually
managing the merges to and from this repository.
Everything was going great until I typed 'repo sync' and it rebased
my manually-merged tree. Hence the option to skip it.

urllib2 returns a malformed HTTPError object in certain situations.
For example, urllib2 has a couple of places where it creates an
HTTPError object with no fp:
if self.retried > 5:
# retry sending the username:password 5 times before failing.
raise HTTPError(req.get_full_url(), 401, "basic auth failed",
headers, None)
When it does that, HTTPError's ctor doesn't call through to
addinfourl's ctor:
# The addinfourl classes depend on fp being a valid file
# object. In some cases, the HTTPError may not have a valid
# file object. If this happens, the simplest workaround is to
# not initialize the base classes.
if fp is not None:
self.__super_init(fp, hdrs, url, code)
Which means the 'headers' slot in addinfourl is not initialized and
info() fails. It is completely insane that urllib2 decides not to
initialize its own base class sometimes.

After a $GIT_URL/clone.bundle has been applied to the new local
repository, perform an incremental fetch using `git fetch` to ensure
the local repository is up-to-date. This allows the hosting server
to offer stale /clone.bundle files to bootstrap a new client.
If a single git fetch fails, it may succeed again after a short
delay. Transient failures are typical in environments where the
remote Git server happens to have limits on how many requests it
can serve at once (the anonymous git daemon, or an HTTP server).
Wait a randomized delay between 30 and 45 seconds and retry the
failed project once. This delay gives the site time to recover
from a transient traffic spike, and the randomization makes it less
likely that a spike occurs again from all of the same clients.

An HTTP (or HTTPS) based remote server may now offer a 'clone.bundle'
file in each repository's Git directory. Over an http:// or https://
remote repo will first ask for '$URL/clone.bundle', and if present
download this to bootstrap the local client, rather than relying
on the native Git transport to initialize the new repository.
Bundles may be hosted elsewhere. The client automatically follows a
HTTP 302 redirect to acquire the bundle file. This allows servers
to direct clients to cached copies residing on content delivery
networks, where the bundle may be closer to the end-user.
Bundle downloads are resumeable from where they last left off,
allowing clients to initialize large repositories even when the
connection gets interrupted.
If a bundle does not exist for a repository (a HTTP 404 response
code is returned for '$URL/clone.bundle'), the native Git transport
is used instead. If the client is performing a shallow sync, the
bundle transport is not used, as there is no way to embed shallow
data into the bundle.

The manifest project has - by design - not a review URL associated

repo currently examines every non-published branch. This is problematic
for my workflow. I have many branches in my kernel tree. Many of these
branches are based off of upstream remotes (I have many remotes) and
will never be uploaded (they'll get sent upstream as a patch).
Having repo scan these branches adds to my upload processing time

In the current version of repo checkout, we often get the error:

All repo-level hooks are expected to live in a single project at the
top level of that project. The name of the hooks project is provided
in the manifest.xml. The manifest also lists which hooks are enabled
to make it obvious if a file somehow failed to sync down (or got
deleted).
Before running any hook, we will prompt the user to make sure that it
is OK. A user can deny running the hook, allow once, or allow
"forever" (until hooks change). This tries to keep with the git
spirit of not automatically running anything on the user's computer
that got synced down. Note that individual repo commands can add
always options to avoid these prompts as they see fit (see below for
the 'upload' options).
When hooks are run, they are loaded into the current interpreter (the
one running repo) and their main() function is run. This mechanism is
used (instead of using subprocess) to make it easier to expand to a
richer hook interface in the future. During loading, the
interpreter's sys.path is updated to contain the directory containing
the hooks so that hooks can be split into multiple files.
The upload command has two options that control hook behavior:
- no-verify=False, verify=False (DEFAULT):
If stdout is a tty, can prompt about running upload hooks if needed.
If user denies running hooks, the upload is cancelled. If stdout is
not a tty and we would need to prompt about upload hooks, upload is
cancelled.
- no-verify=False, verify=True:
Always run upload hooks with no prompt.
- no-verify=True, verify=False:
Never run upload hooks, but upload anyway (AKA bypass hooks).
- no-verify=True, verify=True:
Invalid
Sample bit of manifest.xml code for enabling hooks (assumes you have a
project named 'hooks' where hooks are stored):
<repo-hooks in-project="hooks" enabled-list="pre-upload" />
Sample main() function in pre-upload.py in hooks directory:
def main(project_list, **kwargs):
print ('These projects will be uploaded: %s' %
', '.join(project_list))
print ('I am being a good boy and ignoring anything in kwargs\n'
'that I don\'t understand.')
print 'I fail 50% of the time. How flaky.'
if random.random() <= .5:

This renaming was done for two reasons:
1. The hooks are actually project-level hooks, not repo-level
hooks. Since we are talking about adding repo-level hooks,
It keeps things less confusing if we name the existing hooks

2. The function is a private function in project.py and so
should have capitalization to match.
I also added a docstring describing this function.

There was a minor typo that would cause repo to (I believe)
mistakenly identify any file that contained a substring of the

'mit' or the file 'msg' would be treated as a commit message hook.
I believe that it was intended that repo only recognize files
named exactly 'commit-msg'.

This is almost always something the user needs to address
before continuing work, so promoting it to a failure (rather
than simply an informational message) seems the right way to
go. As a side-effect, repo will now exit with a non-zero
status code in this situation, so pipelines of the form
`repo sync && make` will fail if there are branches that
are stalled due to uploaded but unmerged patches.
If a local git repository exists within the same folder as a new project that
is added, when the user syncs the repo, the sync will overwrite the local
files under the project's .git repository with its own symlinks. Make sure
that we do not overwrite 'normal' files in repo and throw an error when
that happens.
If an email address in a commit object contains a space, like a few

many splits to perform. Here we want only 1 split, to break apart
the commit identity from the email address on the same line.

The trick of looking at the reflog for the remote tracking branch
and only going back one commit works some of the time, but not all of
the time. Its sort of relying on the fact that the user didn't use
`repo sync -n` or `git fetch` to only update the tracking branches
and skip the working directory update.
Doing this right requires looking through the history of the SHA-1
source (what the upstream used to be) and finding a spot where the
DAG diveraged away suddenly, and consider that to be the rewind
point. That's really difficult to do, as we don't have a clear
picture of what that old point was.
A close approximation is to list all of the commits that are in
HEAD, but not the new upstream, and rebase all of those where the
committer email address is this user's email address. In most cases,
this will effectively rebase only the user's new original work.
If the user is the project maintainer and rewound the branch
themselves, and they don't want all of the commits they have created
to be rebased onto the new upstream, they should handle the rebase
on their own, after the sync is complete.

The reader caches refs based upon file mtimes. If any single ref
file has been modified since the last read, we re-read the entire
repository's ref namespace. This simplifies the code as we don't
need to worry about shooting down symbolic-refs, but it may cause
more IO than is necessary if only one ref gets updated.

Fast-forward output is now prefixed with the project header, so the

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.

Now that Gerrit2 has been released and the only supported upload
protocol is direct git push over SSH we no longer need the large
and complex protobuf client library, or the upload chunking logic
in gerrit_upload.py.

In Gerrit2 uploads are sent over "git push ssh://...", as this
is a more efficient transport and is easier to code from external
scripts and/or direct command line usage by an end-user.
Gerrit1's HTTP POST based format is assumed if the review server
does not have the /ssh_info URL available on it.

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.
Thanks to Barry Silverman <barry@disus.com> for spotting the
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
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.

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.

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.

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.
