898e12a2d9 Permit - in URL schemes for special URLs
Clients might be using their own special git-remote-* helper that
has a hypen in its name. Permit - in the scheme part of the URL
when trying to decide if it is an SSH URL and assume it is *not*
SSH if the URL matches "foo-bar://" style.

76abcc1d1e repo status to print project name on clean gits
repo status just prints "# on branch oprofile" if you have branched
in clean status. This doesn't really tell which branch is meant.

Instead we can use the same syntax with modified gits which will
give us detailed information.

d315382572 Add 'rebase="false"' attribute to the <project/> XML.
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.

There is also shortcuts in case if the "current branch" is
a persistent revision such as tag or sha1. We check if the
persistent revision is present locally and if it does - do
no fetch anything from the server.

This greately reduces sync time and size of the on-disk repo

fab96c68e3 Work around Python 2.7 urllib2 bug
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.

29472463ba Work around Python 2.7 failure to initialize base class
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.

c325dc35f6 sync: Fetch after applying bundle and retry after errors
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.

f322b9abb4 sync: Support downloading bundle to initialize repository
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.

65e0f35fda Add commit-msg hook also for manifest project
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/...).

d6c93a28ca Add branch support to repo upload
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.

3ba5f95b46 Fixed repo checkout error message when git reports errors.
In the current version of repo checkout, we often get the error:
  error: no project has branch xyzzy

...even when the actual error was something else.  This fixes it
to only report the 'no project has branch' when that is actually true.

This fix is very similar to one made for 'repo abandon':
  https://review.source.android.com/#change,22207

The repo checkout error is filed as: <http://crosbug.com/6514>

TEST=manual

A sample creating a case where 'git checkout' will fail:

  $ repo start branch1 .
  $ repo start branch2 .
  $ touch bogusfile
  $ git add bogusfile
  $ git commit -m "create bogus file"
  [branch2 f8b6b08] create bogus file
   0 files changed, 0 insertions(+), 0 deletions(-)
   create mode 100644 bogusfile
  $ echo "More" >> bogusfile
  $ repo checkout branch1 .
  error: chromite/: cannot checkout branch1

A sample case showing that we still fail if no project has a branch:

  $ repo checkout xyzzy .
  error: no project has branch xyzzy

37282b4b9c Support repo-level pre-upload hook and prep for future hooks.
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.')

8ced8641c8 Renamed 'repo_hooks' function to '_ProjectHooks'.
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.

2536f80625 Fixed bug identifying 'commit-msg' files.
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'.

4c50deea28 Fail sync when encountering "N commits behind."
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.

8ad8a0e61d Change DWIMery hack for dealing with rewound remote branch
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.

d237b69865 Implement git ref reading purely in Python
Its much faster to read the refs from 114 projects when the reader
is pure Python and just doing file IO than forking 114 git commands
and parsing their output.

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.

This change drops `repo branches` in Android from 1.658s to 0.206s.
Likewise, `repo sync` improves dramatically as well.

350cde4c4b Change repo sync to be more friendly when updating the tree
We now try to sync all projects that can be done safely first, before
we start rebasing user commits over the upstream.  This has the nice
effect of making the local tree as close to the upstream as possible
before the user has to start resolving merge conflicts, as that extra
information in other projects may aid in the conflict resolution.

Informational output is buffered and delayed until calculation for
all projects has been done, so that the user gets one concise list
of notice messages, rather than it interrupting the progress meter.

Fast-forward output is now prefixed with the project header, so the
user can see which project that update is taking place in, and make
some relation of the diffstat back to the project name.

Rebase output is now prefixed with the project header, so that if
the rebase fails, the user can see which project we were operating
on and can try to address the failure themselves.

Since rebase sits on a detached HEAD, we now look for an in-progress
rebase during sync, so we can alert the user that the given project
is in a state we cannot handle.

It uses --ignore-if-in-upstream when generating the patch series

a rename case just as well as the cherry-pick variant used by -m.

6a5644d392 Get rid of the horrible android import work around hack
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.

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

0734600ce0 Fix 'repo sync' when the remote reflog has only 1 entry
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.
