In order to better analyze and track repo errors, repo command failures
need to be tied to specific errors in repo source code.
Additionally a new GitCommandError was added to differentiate between
general git related errors to failed git commands. Git commands that opt
into verification will raise a GitCommandError if the command failed.
The first step in this process is a general error refactoring

Allow the user to specify relative or absolute or any other funky
path that they want when using `repo init` or `repo sync`. Our
goal is to restrict the paths in the remote manifest git repo we
cloned from the network, not protect the user from themselves.

Added "--use-superporject" option to sync.py to fetch project SHAs from
superproject. If there are any missing projects in superprojects, it
prints the missing entries and exits. If there are no missing entries,
it will use SHAs from superproject to fetch the projects from git.
Tested the code with the following commands.
$ ./run_tests tests/test_manifest_xml.py
$ ./run_tests -v tests/test_git_superproject.py
$ ./run_tests -v
Tested the sync code by copying all the repo changes into my Android
AOSP checkout and adding <superporject> tag to default.xml. With
local modification to the code to print the status,
.../WORKING_DIRECTORY$ repo sync --use-superproject
repo: executing 'git clone' url: sso://android/platform/superproject

The old "manifest required for this command -- please run
init" is replaced by a more helpful message that lists the
command repo was trying to execute (with arguments) as well
as the str() of the NoManifestException. For example:
> error: in `sync`: [Errno 2] No such file or directory:
> 'path/to/.repo/manifests/.git/HEAD'
> error: manifest missing or unreadable -- please run init
Other failure points in basic command parsing and dispatch
are more clearly explained in the same fashion.

The groups act on a group= attribute specified on projects in the
manifest.
All projects are implicitly labelled with "default" unless they are
explicitly labelled "-default".
Prefixing a group with "-" removes matching projects from the list

If any non-inverted manifest groups are specified, the default label

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.

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 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.
