3164d40e22 use open context managers in more places
Use open() as a context manager to simplify the close logic and make
the code easier to read & understand.  This is also more Pythonic.

f454512619 sync: make .git init more robust
Hitting Ctrl-C in the middle of this func will leave the .git in a
bad state that requires manual recovery.  The code tries to catch
all exceptions and recover by deleting the incomplete .git dir, but
it omits KeyboardInterrupt which Exception misses.

We could add that to the recovery path, but we can make this more
robust with a different approach: set up everything in .git.tmp/
and only move it to .git/ once we've fully initialized it.

c8290ad49e project: allow CurrentBranch to return None on errors
If the repo client checkout is in an incomplete sync state, the work
git repo might be in a bad way.  Turn errors parsing HEAD into None
since callers of CurrentBranch already need to account for it.

70d861fa29 sync: improve output with intermingled progress bars and status
When displaying progress bars, we use \r to reset the cursor to the
start of the line before showing the new update.  This assumes the
new line will fully erase whatever was displayed there previously.
The "done" codepath tries to handle this by including a few extra
spaces at the end of the message to "white out" what was there.

Lets replace that hack with the standard ECMA escape sequence that
clears the current line completely.  This is the CSI "erase in line"
sequence that the terminal will use to delete all content.  The \r
is still needed to move the cursor to the start of the line.  Using
this sequence should be OK since we're already assuming the terminal
is ECMA compliant with our use of coloring sequences.  We also put
the \r after the CSI sequence on the off chance the terminal can't
process it and displays a few bytes of garbage.

The other improvement is to the syncbuffer API.  When it dumps its
status information, it almost always comes after a progress bar
update which leads to confusing comingled output.  Something like:
  Fetching projects: 100% (2/2) error: src/platform2/: branch ...
Since the progress bar is "throw away", have the syncbuffer reset
the current output to the start of the line before showing whatever
messages it has queued.

600f49278a project: fix encoding handling with git commands
The GitCommand Wait helper takes care of decoding bytes to strings
for us.  That means we don't have to decode stdout ourselves which
is what our local rev list, ls-remote, and generic get_attr helpers
were doing.

If we don't use Wait though to capture the output but instead go
directly to the subprocess stdout, we do have to handle decoding
ourselves.  This is what the diff helpers were doing.

f7c51606f0 hooks: support external hooks running different Python version
As we convert repo to support Python 3, the version of Python that we
use might not be the version that repo hooks users have written for.
Since repo upgrades are not immediate, and not easily under direct
control of end users (relative to the projects maintaining the hook
code), allow hook authors to declare the version of Python that they
want to use.

Now repo will read the shebang from the hook script and compare it
against the version of Python repo itself is running under.  If they
differ, we'll try to execute a separate instance of Python and have
it load & execute the hook.  If things are compatible, then we still
use the inprocess execution logic that we have today.

This allows repo hook users to upgrade on their own schedule (they
could even upgrade to Python 3 ahead of us) without having to worry
about their supported version being exactly in sync with repo's.

745be2ede1 Add support for partial clone.
A new option, --partial-clone is added to 'repo init' which tells repo
to utilize git's partial clone functionality, which reduces disk and
bandwidth usage when downloading by omitting blob downloads initially.
Different from restricting clone-depth, the user will have full access
to change history, etc., as the objects are downloaded on demand.

81f5c59671 project: rev_list: simplify execution
Currently we read the binary stream from the subprocess code directly
before waiting for it to finish, but there's no need to do so as we
aren't streaming the output to the user.  This also means we pass up
binary data to the caller as we don't go through GitCommand's internal
logic which decodes the stream as utf-8.

Simplify the code by calling Wait first, then splitting the entire
captured output in one line.

c5b0e23490 project: Set config option to skip lfs process filter
During sync, repo runs `git read-tree --reset -u -v HEAD` which causes
git-lfs's smudge filter to run, which fails because git-lfs does not
work with bare repositories.

This was fixed in I091ff37998131e2e6bbc59aa37ee352fe12d7fcd to
automatically disable this smudge filter. However, later versions of
Git (2.11.0) introduced a new filter protocol [1], to avoid spawning
a new command for each filtered file. This was implemented in Git-LFS
1.5.0 [2].

This patch fixes the issue by setting the git lfs process filter, in
addition to the smudge filter. For any projects that have LFS objects,
`git lfs pull` must still be executed manually afterwards.

e57f1146de sync: respect --force-sync when fetching updates
If a tag is rewritten on the server (which is bad), trying to recover
locally with `repo sync --force-sync` doesn't actually work.  People
have to manually delete things themselves to fix syncing.  While tags
should never be rewritten in practice, allow users to easily recover
from broken servers.

"Allow clobbering of existing tags from remote."), but the incremental
update flow was missed.

disable sending emails completely.

     patches uploaded without these command line options still trigger

09f0abb0ef init: --dissociate option to copy objects borrowed with --reference
"repo init --reference" has two purposes: to decrease bandwidth used
at clone time, and to decrease disk usage afterward, by using the
reference repositories as an alternate store of objects even after
the clone. The downside is that it makes the borrowing repositories
dependent on the reference repositories, so it is easy to end up
with missing objects by mistake after a cleanup operation like "git
gc".

To prevent that, v2.3.0-rc0~30^2 (clone: --dissociate option to mark
that reference is only temporary, 2014-10-14), "git clone" gained a
--dissociate option that makes --reference reuse objects from the
reference repository at clone time but copy them over instead of
using the reference as an alternate. This is more straightforward to
use than plain --reference, at the cost of higher disk usage.

Introduce a --dissociate to "repo init" that brings the same benefits
to repo. The option is simply passed on to "git clone".

Martin Kelly
e4e94d26ae init: add --submodules to sync manifest submodules
repo sync can sync submodules via the --fetch-submodules option.
However, if the manifest repo has submodules, those will not be synced.
Having submodules in the manifest repo -- while not commonly done -- can
be useful for inheriting a manifest from another project using <include>
and layering changes on top of it.  In this way, you can avoid having to
deal with merge conflicts between your own manifests and the other
project's manifests (for example, if you're managing an Android fork).

Add a --submodule option to init that automatically syncs the submodules
in the manifest repo whenever the manifest repo changes.

6c5944606a Fix checkout error when depth passed to repo init and revision is a sha1
Currently, if direct fetch of a sha1 is not supported by git server and
depth option is used, we fallback on syncing the upstream branch by
ignoring depth option.

This fallback doesn't work in next 2 cases:
(1) upstream attribute is not specified in manifest
(2) depth option is passed to repo init command
    (not with clone-depth attribute in manifest)

This commit do the following:
- fixes (1) by updating condition used to apply fallback
  first we retry with depth set to None, then by syncing all branches
- fixes (2) by passing depth as argument of _RemoteFetch() method
  thus, its value is not set again to depth value passed to repo init
  command when applying fallback

A common use case is when performing a full-workspace

    repo forall -c git merge <some tag>

And then produce a short list of conflicted projects via:

    repo status -q

The integrator can then iteratively fix and clean up all conficted
components.  The merge is complete when:

    repo status -q

    returns no output.

40252c20f7 RepoHook: allow users to approve hooks via manifests
The constant prompting when registered hooks change can be tedious and
has a large multiplication factor when the project is large (e.g. the
AOSP).  It gets worse as people want to write more checks, hooks, docs,
and tests (or fix bugs), but every CL that goes in will trigger a new
prompt to approve.

Let's tweak our trust model when it comes to hooks.  Since people start
off by calling `repo init` with a URL to a manifest, and that manifest
defines all the hooks, anchor trust in that.  This requires that we get
the manifest over a trusted link (e.g. https or ssh) so that it can't
be MITM-ed.  If the user chooses to use an untrusted link (e.g. git or
http), then we'll fallback to the existing hash based approval.

76a4a9df86 project: Set config option to skip lfs smudge filter
During sync, repo runs `git read-tree --reset -u -v HEAD` which causes
git-lfs's smudge filter to run. However this fails because git-lfs does
not work with bare repositories.

Add lfs.filter configuration to the project config as suggested in the
comments on the upstream git-lfs client issue [1]. This prevents the
smudge filter from running, and the sync completes successfully.

For any projects that have LFS objects, `git lfs pull` must be executed.

another RemoteSpec parameter, only used to write the manifest out.

f9fe3e14d2 repo: Repo does not always handle '.' parameter correctly
The repo script allows a manifest to specify a '.' as the path the
top-level directory, which co-locates the .git and .repo directories,
and places files from the git repository at the top-level:

  <project name="proj_name" path="." />
  <project name="sierra.other.git" path="other" />

Most commands work correctly with this setup. Some commands, however,
fail to find the project. For instance, 'repo sync' works, and 'repo sync .'
works in a sub-project ('other' in this case) but 'repo sync .' in the
top-level directory fails with the error:

error: project . not found

There are two reasons for this:

1. The self.worktree attribute of the Project object is not normalized,
so with a '.' for path its value would be '/my/project/root/.'. This is
fine when used as a path, since it's the same path as '/my/project/root',
but when used in a string comparison it fails. This commit applies
os.path.normpath() to that value before storing it.

2. The _GetProjectByPath method in command.py was not checking the path
against manifest.topdir, so even once it was normalized the project was
not found. This commit adds a check against manifest.topdir if the
loop drops out without finding a project.

bdb866ea76 Fix symlinking of new projects
We weren't copying these lists, so the += was actually changing the
underlying lists.

When a new project was added to the manifest, we run _CheckDirReference
against the manifest project with share_refs=True, which added the
working_tree_* to the shareable_* lists. Then, when we load the new
manifest and create the new project, it uses the lists that already
contain the working_tree_* files, even though we passed
share_refs=False.

This happens reliably under the above conditions, but doesn't seem to
happen when syncing a fresh tree. So we've got a mixture of links that
may need to be cleaned up later. This patch will just stop it from
happening in the future.

Add repo start support for GITC checkouts. If the user is in
the GITC FS view, they can now run repo start to check out
the sources and create a new working branch.

When "repo start" is called on a GITC project, the revision
tag is set to an empty string and saved in a new tag:
old-revision. This tells the GITC filesystem to display the
local copy of the sources when being viewed. The local copy
is created by pulling the project sources and the new branch
is created based off the original project revision.

Updated main.py to setup each command's gitc_manifest when
appropriate.

Updated repo sync's logic to sync opened projects and
updating the GITC manifest file for the rest.

f9b7683a3b Include project path in --force-sync error message
For projects that have been cloned outside of the repo command (or
cloned a long time ago), commit abaa7f312f
introduced an error message to invite the user to use --force-sync.
However, due to the risk of data loss, it's useful to know which
project's git directory is being replaced before deciding whether or not
to provide --force-sync.

This change updates the exception's associated value to include the
project's relative path and explain to the user how they can resolve the
issue. A previous version of this commit used the project name. However,
for projects that have multiple work trees, the name can be ambiguous,
while the path clearly identifies which git directory will be replaced.

changes. Switching between two clone-depth="1" branches will fetch far
more than the top commit.

Instead, when not using clone-depth, pass --depth=2147483647 to git
fetch so that it ensures that we have the entire history. That is
slightly less efficient, so limit it to only when there are shallow
objects in the project by checking for the existance of the 'shallow'
file.

2a3e15217a Fix _ReferenceGitDir symlinking
This fixes these errors:

  ...
  File ".repo/repo/project.py", line 2371, in _ReferenceGitDir
    os.symlink(os.path.relpath(src, os.path.dirname(dst)), dst)
  OSError: [Errno 17] File exists

Which was happening for checkouts that were created before v1.12.8, when
project-objects was created. Nothing had yet been forcing these
checkouts to use project-objects, until the recent verification changes.

In this OSError case, we already created the symlink, so src == dst, and
the directory did not exist. This caused us to run os.makedirs the
os.symlink on the same file.

dst really should be the file in gitdir, not the target of that symlink
if it exists. So just use realpath for the dotgit portion of the path.

abaa7f312f Add option to correct gitdir when syncing
In some cases, a user may wish to continue with a sync even though
it would require overwriting an existing git directory. This behavior
is not safe as a default because it could result in the loss of some
user data, but as an optional flag it allows the user more flexibility.

To support this, add a --force-sync flag to the sync command that will
attempt to overwrite the existing git dir if it is specified and the
existing git dir points to the wrong obj dir.

b1a07b8276 InitGitDir: Clean up created directories
If _InitGitDir fails, it leaves any progress it had made on the file
system. This can cause subsequent calls to repo sync to behave
differently. This is especially evident when _CheckDirReference() fails,
since it will not be invoked when sync is retried because both the
source and destination directories already exist.

To address this, have _InitGitDir() clean up any directories it has created
if it catches an exception. Also behave the same way for _InitWorkTree().
