If the remote is using authenticated HTTP, but does not have
$GIT_URL/clone.bundle files in each repository, an initial sync
would fail around 8 projects in due to the library not resetting
the number of failures after getting a 404.
Work around this by updating the retry counter ourselves.
The urllib2 library is also not thread-safe. Make it somewhat
safer by wrapping the critical section with a lock.

Not every version of urllib2 supplies a reason object on the
HTTPError exception that it throws from urlopen(). Work around
this by using str(e) instead and hope the string formatting includes
sufficient information.

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.

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.

The manifest project has - by design - not a review URL associated
with it. It is actually not even a 'project' in repo's sense.
This will prevent the commit-msg hook from being added, which is
not necessarily wanted as the project is managed in gerrit.
This commit will enable the commit-msg hook, which in turn will
add the Change-Id-line to every new commit in it. This simplifies
replacing patch sets (by git push ... refs/for/...).

This commit adds a --br=<branch> option to repo upload.
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
and clutters the branch selection buffer. I've also seen repo get
confused when one of my branches is 1000s of commits different from
m/master.

It is undesired to have the same Change-Id:-line for two separate
commits, and when cherry-picking, the user must manually change it.
If this is not done, bad things may happen (such as when the user
is uploading the cherry-picked commit to Gerrit, it will instead
see it as a new patch-set for the original change, or worse).
repo cherry-pick works the same was as git cherry-pick, except that
it replaces the Change-Id with a new one and adds a reference
back to the commit from where it was picked.
On failures (when git can not successfully apply the cherry-picked
commit), instructions will be written to the user.

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:
raise Exception('Pre-upload hook failed. Have a nice day.')

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
to be "ProjectHooks"
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
word 'commit-msg' as a commit message hook. For example, the file
'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'.

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.
