* Add more file i/o wrappers in platform_utils to allow using
long paths (length > MAX_PATH) on Windows.
* Paths using the long path syntax ("\\?\" prefix) should never
escape the platform_utils API surface area, so that this
specific syntax is not visible to the rest of the repo code base.
* Forward many calls from os.xxx to platform_utils.xxx in various place
to ensure long paths support, specifically when repo decides to delete
obsolete directories.
* There are more places that need to be converted to support long paths,
this commit is an initial effort to unblock a few common use cases.

"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".

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.

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

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.

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.

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.

For projects that have been cloned outside of the repo command (or

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.

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
fail for projects that don't have an explicit revision specified,
and don't have a branch of the same name as the default revision.
For example, a manifest defining a default revision:
<default revision="master">
having a project without an explicit revision:
<project name="path/to/project">
and not having a branch named "master", will cause repo sync to
fail for that project with the error:

When running repo branch, the git merge line (in many circumstances)
is set to the revision of the project specified in the manifest. If
this is a branch name that is not fully-qualified, we will end up with
something like "merge = master" instead of "merge = refs/heads/master".
This change examines the revision if we are going to use that and
changes branch short names to fully qualified branch names.

Switch the GitCommand program to always capture the output for stdout
and stderr. And by default print the output while running.
The options capture_stdout and capture_stderr have effectively become
options to supress the printing of stdout and stderr.
Update the 'git fetch' to use '--progress' so that the progress messages
will be displayed. git checks if the output location isatty() and if it
is not a TTY it will by default not print the progress messages.

This reverts commit 38e4387f8e.
A "repo init" followed by "repo sync" is meant to be as safe as
"git clone". In particular it should not run arbitrary code provided
by the manifest owner.
It would still be nice to have support for manifest-defined git hooks
--- they'd just need a prompt like the upload RepoHook has. Hopefully
a later change can bring them back.

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
consistently shallow as opposed to growing over time, especially when merges
are involved.

The persistent proxy may choose to present a per-process cookie file
that gets cleaned up after the process exits, to help with the fact
that libcurl cannot save cookies atomically when a cookie file is
shared across processes. We were letting this cleanup happen
immediately by closing stdin as soon as we read the configuration
option, resulting in a nonexistent cookie file by the time we use the
config option.
Work around this by converting the cookie logic to a context manager
method, which closes the process only when we're done with the cookie

A recent optimization (2fb6466f79) skips

"""""""""

branch1=<branch name>
branch2=<branch name>
project=<project with revision set to different sha1 in each branch>
repo init -u $url -b $branch1 --mirror
repo sync $project
first=$(cd $project.git; git rev-parse HEAD)
repo init -b $branch2
repo sync $project
second=$(cd platform/build.git; git rev-parse HEAD)
if [[ $first == $second ]]

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.

The user can delete the options and retry the upload.
- If a topic was set the options will be read as part of the

(Previous submission of this change broke Android buildbot due to
incorrect regular expression for parsing git-config output. During
investigation, we also found that Android, which pulls Chromium, has a
workaround for Chromium's submodules; its manifest includes Chromium's
submodules. This new change, in addition to fixing the regex, also
take this type of workarounds into consideration; it adds a new
attribute that makes repo not fetch submodules unless submodules have a
project element defined in the manifest, or this attribute is
overridden by a parent project element or by the default element.)
We need a representation of git-submodule in repo; otherwise repo will
not sync submodules, and leave workspace in a broken state. Of course
this will not be a problem if all projects are owned by the owner of the
manifest file, who may simply choose not to use git-submodule in all
projects. However, this is not possible in practice because manifest
file owner is unlikely to own all upstream projects.
As git submodules are simply git repositories, it is natural to treat
them as plain repo projects that live inside a repo project. That is,
we could use recursively declared projects to denote the is-submodule
relation of git repositories.
The behavior of repo remains the same to projects that do not have a
sub-project within. As for parent projects, repo fetches them and their
sub-projects as normal projects, and then checks out subprojects at the
commit specified in parent's commit object. The sub-project is fetched
at a path relative to parent project's working directory; so the path
specified in manifest file should match that of .gitmodules file.
If a submodule is not registered in repo manifest, repo will derive its
properties from itself and its parent project, which might not always be
correct. In such cases, the subproject is called a derived subproject.
To a user, a sub-project is merely a git-submodule; so all tips of
working with a git-submodule apply here, too. For example, you should
not run `repo sync` in a parent repository if its submodule is dirty.

We need a representation of git-submodule in repo; otherwise repo will
not sync submodules, and leave workspace in a broken state. Of course
this will not be a problem if all projects are owned by the owner of the
manifest file, who may simply choose not to use git-submodule in all
projects. However, this is not possible in practice because manifest
file owner is unlikely to own all upstream projects.
As git submodules are simply git repositories, it is natural to treat
them as plain repo projects that live inside a repo project. That is,
we could use recursively declared projects to denote the is-submodule
relation of git repositories.
The behavior of repo remains the same to projects that do not have a
sub-project within. As for parent projects, repo fetches them and their
sub-projects as normal projects, and then checks out subprojects at the
commit specified in parent's commit object. The sub-project is fetched
at a path relative to parent project's working directory; so the path
specified in manifest file should match that of .gitmodules file.
If a submodule is not registered in repo manifest, repo will derive its
properties from itself and its parent project, which might not always be
correct. In such cases, the subproject is called a derived subproject.
To a user, a sub-project is merely a git-submodule; so all tips of
working with a git-submodule apply here, too. For example, you should
not run `repo sync` in a parent repository if its submodule is dirty.

Currently when doing a sync against a revision locked manifest,
sync has no option but to fall back to sync'ing the entire refs space;
it doesn't know which ref to ask for that contains the sha1 it wants.
This sucks if we're in -c mode; thus when we generate a revision
locked manifest, record the originating branch- and try syncing that
branch first. If the sha1 is found within that branch, this saves
us having to pull down the rest of the repo- a potentially heavy
saving.
If that branch doesn't have the desired sha1, we fallback to sync'ing
everything.

The fix for issue #46 in 5d016502eb appears to break syncing in some
situations: the branch is deleted after the point where it's been
configured, which deletes part of its configuration and causes the
config to change each time you call `repo init`, alternating between a
configuration that works and one that doesn't.
Instead of deleting the branch with git branch -D, use git update-ref -d
which just deletes the ref (to avoid the rebase) without touching the
configuration for the branch that was set up during the first repo init.
This appears to ensure the config is left in a valid state all the time
no matter what combination of repo init commands you run, without
reintroducing the rebasing issue.

This patch fixes repo behaviour when running sync -d with unmodified
topic branches.
Prior to this patch sync -d would see the latest revision is already
checked out, thus staying on the branch. Since "-d" means detach we
should follow git's behaviour and actually detach from the branch in
that case.
Basic test case - after a fresh repo init + sync -
* repo start --all testdetach
* repo sync -d
* repo status
-> status shows active topic branch "testdetach",
should show :
nothing to commit (working directory clean)

https://code.google.com/p/git-repo/issues/detail?id=46
When using repo init -b on an already existing repository,
the next sync will try to rebase changes coming from the old manifest
branch onto the new, leading in the best case scenario to conflicts

There are use-cases when fetching all branch is impractical and
we really need to fetch only one branch/tag.
e.g. there is a large project with binaries and every update of a
binary file is put to a separate branch.
The whole project history might be too large to allow users fetch it.
Add 'sync-c' option to 'project' and 'default' tags to make it possible
to configure 'sync-c' behavior at per-project and per-manifest level.

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.

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.')

This renaming was done for two reasons:
1. The hooks are actually project-level hooks, not repo-level

2. The function is a private function in project.py and so

I believe that it was intended that repo only recognize files

If the -t flag is given to upload, the local branch name is
automatically sent to Gerrit Code Review as the topic branch name
for the change(s). This requires the server to be Gerrit Code
Review v2.1.3-53-gd50c94e or later, which isn't widely deployed
right now, so the default is opt-out.

If a tagged commit is not reachable by the fetch refspec configured
for the git (usually refs/heads/*) it will not be downloaded by
'git fetch'. The tag can however be downloaded with 'git fetch
--tags' or 'git fetch tag <tag>'.
This patch fixes the situation when a tag is not found after a
'git fetch'. Repo will issue 'git fetch tag <tag>' before giving
up completely.

Most users of repo are also using Gerrit Code Review, and will want
the commit-msg hook to be automatically installed into their local
projects so that Change-Ids are assigned when commits are created,
not when they are first uploaded.
(cherry picked from commit a949fa5d20
but squashed with latest hook script from version 2.1.2)

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.
If a local git repository exists within the same folder as a new project that
is added, when the user syncs the repo, the sync will overwrite the local
files under the project's .git repository with its own symlinks. Make sure
that we do not overwrite 'normal' files in repo and throw an error when
that happens.
If an email address in a commit object contains a space, like a few
malformed ones on the Linux kernel, we still want to split only on
the first space.
Unfortunately my brain was too damaged by Perl and originally wrote
the split asking for 2 results; in Python split's argument is how
many splits to perform. Here we want only 1 split, to break apart
the commit identity from the email address on the same line.

We accidentally introduced this message during 1.6.8 by always
invoking `git rebase` when there were no new commits from the
upstream, but the user had local commits.

The revisionExpr field now holds an expression from the manifest,
such as "refs/heads/master", while revisionId holds the current
commit-ish SHA-1 of the revisionExpr. Currently that is only
filled in if the manifest points directly to a SHA-1.

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.

We now feed Project a RemoteSpec, instead of the Remote directly
from the XmlManifest. This way the RemoteSpec already has the
full project URL, rather than just the base, permitting other
types of manifests to produce the URL in their own style.

These aren't that widely used, and actually make it difficult for
users to fully mirror a forest of repositories, and then permit
someone else to clone off that forest, rather then the original
upstream servers.

Performance improvements in repo sync caused us to skip out of the
initial Sync_LocalHalf without ever running CopyFiles, so we didn't
create the top level Makefile in new clients whose manifest request
one with a <copyfile> element.
Now we run CopyFiles after the initial read-tree that populates
the project working directory.

If the current branch is published, but all published commits are
merged into the manifest revision, but there is also at least one
unpublished commit on the current branch, we should rebase the
unpublished commit, rather than creating a merge commit.

By creating a background ssh "control master" process which lives
for the duration of our sync cycle we can easily cut the time for
a no-op sync of 132 projects from 60s to 18s.
