When sync-s="true" option is used, the checkout of a submodule will try

If this revision is a named reference, the checkout will fail if there
is no reference with this name in the submodule.
The proposed solution is to use the git commit id as revisionExpr for
submodules.

When the alias attribute is set for a remote, the RemoteSpec attached to
a Project only contains the alias name used by git, not the original
name used in the manifest. But that's not enough information to
reconstruct the manifest, so save off the original manifest name as
another RemoteSpec parameter, only used to write the manifest out.

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.

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.

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.

The existing code here makes sure that switching clone-depth from on to
off actually causes the history to be fully restored. Unfortunately, it
does this by fetching the full history every time the fetch spec
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.

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.

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.

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().

The fetch logic for the case where depth is set and revision is a
SHA1 has several failure modes that are not handled well by the
current logic.
1) 'git fetch <SHA1>' requires git version >= 1.8.3
2) 'git fetch <SHA1>' can be prevented by a configuration option on the server.
3) 'git fetch --depth=<N> <refspec>' can fail to contain a SHA1 specified by
the manifest.
Each of these cases cause infinite recursion when _RemoteFetch() tries to call
itself with current_branch_only=False because current_branch_only is set to
True when depth != None.
To try to prevent the infinite recursion, we set self.clone_depth to None
before the first retry of _RemoteFetch(). This will allow the Fetch to
eventually succeed in the case where clone-depth is specified in the manifest.
A user specified depth from the init command will still recurse infinitely.
In addition, never try to fetch a SHA1 directly if the git version being used
is not at least 1.8.3.

The source (target) of the symlink is specified relative to a project
within a tree, and the destination is specified relative to the top
of the tree, so it should always be possible to create a relative symlink

without breaking the symlink, and copying a tree (with -p) without leaving
a symlink to the old tree.

There are a set of cases that can cause the git directory in
.repo/projects to point to a directory in .repo/project-objects that
is not the one specified in the manifest. This results in a tree that
is not sane, and so should cause a failure.
In order to reproduce the failure case:
1) Sync to any manifest
2) Change the 'name' of a project to a different repository. Leave the
'path' the same.
3) Resync the modified project. The project-objects directory will not
be created, and the projects directory will remain pointed at the old
project-objects.

Appending the branch to the fetch spec causes sync of a mirror to

and don't have a branch of the same name as the default revision.
For example, a manifest defining a default revision:

having a project without an explicit revision:
<project name="path/to/project">

Handle the case when this error occurs:
error: some local refs could not be updated; try running
'git remote prune origin' to remove any old, conflicting branches
This is usually caused by a reference getting changed from a file to a
directory.
For example:
Initially someone creates a branch 'foo' and it is stored as:
.git/refs/remotes/origin/foo
Then later on it is decided to change the layout structure where 'foo'
is a directory with branches below it:
.git/refs/remotes/origin/foo/master
The problem occurs when someone still has
'.git/refs/remotes/origin/foo' on their system and does a repo sync.
When this occurs the error message for needing to do a
'git remote prune origin' occurs.
Now when doing a 'git fetch' if the error message from git says that a
'git remote prune' is needed, it will do the prune and then retry the
fetch.

When working within a team or corporation it is often
useful/required to use predefined git templates. This
change teaches repo to use a per-remote git hook template
structure.
The implementation is done as a continuation of the
existing projecthook functionality. The terminology is
therefore defined as projecthooks.
The downloaded projecthooks are stored in the .repo
directory as a metaproject separating them from the users
project forest.
The projecthooks are downloaded and set up when doing a
repo init and updated for each new repo init.
When downloading a mirror the projecthooks gits are
not added to the bare forest since the intention is to
ensure that the latest are used (allows for company policy
enforcement).
The projecthooks are defined in the manifest file in the
remote element as a subnode, the name refers to the
project name on the server referred to in the remote.
<remote name="myremote ..>
<projecthook name="myprojecthookgit" revision="myrevision"/>
</remote>
The hooks found in the projecthook revision supersede
the stock hooks found in repo. This removes the need for
updating the projecthook gits for repo stock hook changes.

Currently, we only use the depth flag when cloning. The result is that when
new project history has merges, the entire history of the merged branch is
brought in and the project becomes unshallow very quickly. --depth and
clone-depth are often used to save on space, not just network load, so this
seems less than ideal.
This change uses --depth on every fetch (when the user has depth specified),
not just the initial clone. The result is that the given project stays

repo sync $project

repo sync $project
second=$(cd platform/build.git; git rev-parse HEAD)

Other failure points in basic command parsing and dispatch
are more clearly explained in the same fashion.

In existing workspaces where the manifest specifies a commit id in the
manifest, we can avoid doing a fetch from the remote if we have the
commit locally. This substantially improves sync times for fully
specified manifests.

This command allows a deeper diff between two manifest projects.
In addition to changed projects, it displays the logs of the
commits between both revisions for each project.

When we do an initial fetch and have not specified any branch etc,
the following fetch command will not error:
git fetch origin --tags +refs/heads/*:refs/remotes/origin/*
In this change we make sure something got fetched and if not we report
an error.
This fixes the bug that occurs when we init using a bad manifest url and
then are unable to init again (because a manifest project has been
inited with no manifest).

Fetching a new branch on a shallow client may download the entire
project history, as the depth parameter is not passed to git
fetch. Force the fetch to only download the current branch.

This significantly reduces sync time and used brandwidth as only
a tar of each project's revision is checked out, but git is not
accessible from projects anymore.
This is relevant when git is not needed in projects but sync
speed/brandwidth may be important like on CI servers when building
several versions from scratch regularly for example.
Archive is not supported over http/https.

If the top-level .repo directory is moved somewhere else (e.g. a
different drive) and replaced with a symlink, _InitHooks() will create
broken symlinks. Resolving symlinks before computing the relative path
for the symlink keeps the path within the repo tree, so the tree can
be moved anywhere.

If git-remote-persistent-https fails, we use an iter() and then
subsequently a .read() on stderr. Python doesn't like this and
gives the following error message:
ValueError: Mixing iteration and read methods would lose data
This change removes the use of iter() to avoid the issue.

* Add .decode('utf-8') where needed
* Add 'b' to `open` where needed, and remove where unnecessary

It is often useful to be able to include the same project more than
once, but with different branches and placed in different paths in the
workspace. Add this feature.
This CL adds the concept of an object directory. The object directory
stores objects that can be shared amongst several working trees. For
newly synced repositories, we set up the git repo now to share its
objects with an object repo.
Each worktree for a given repo shares objects, but has an independent
set of references and branches. This ensures that repo only has to
update the objects once; however the references for each worktree are
updated separately. Storing the references separately is needed to
ensure that commits to a branch on one worktree will not change the
HEAD commits of the others.
One nice side effect of sharing objects between different worktrees is
that you can easily cherry-pick changes between the two worktrees
without needing to fetch them.
