For large projects, clone bundle is useful because it provided a way to
efficiently transfer a large portion of git objects through CDN, without
needing to interact with git server. However, with partial clones, the
intention is to not download most of the objects, so the use of clone
bundles would defeat the space savings normally seen with partial
clones, as they are downloaded before the first fetch.
A new option, --clone-bundle is added to override this behavior.
Add a new repo.clonebundle variable which remembers the choice if
explicitly given from command line at repo init.

Different Python & OS versions have different environ behavior wrt
accepted types & encoding. Since we're migrating to be Python 3 only,
lets change our code to assume strings always work as that's what the
newer Python 3 does. This will fail under Python 2 for some env vars,
mostly on Windows, but the effort of maintaining shim layers that can
handle these edge cases isn't worth it when we're dropping that code.
We leave the logic in the `repo` launcher for now as it is simple, and
we want it to be able to switch versions a bit longer than the rest of
the tree.
Here's the support table:
| *NIX | Windows |
Python 2 | ASCII string | str or bytes, not unicode |
Python 3 | str or bytes | str only |
Windows uses strings natively in its environment all the time. But it
doesn't allow unicode strings under Python 2, so we have to encode.
Python 2 on *NIX is funky in that it always lowers to ASCII, so we had
to manually encode to avoid errors regardless of unicode or str.
Python 3 on Windows & *NIX will accept strings. *NIX will also accept
bytes but Windows will not.

see, but with a shared object dir. Any pruning of objects based on
refs in just one repo can easily break the others.

never prune objects for this exact scenario: there might be refs in

The use case is any situation where your manifest does
not exist on server, but where you still want to do
full sync for the projects, without having your
workspace manifest switched to other branch or
forwarded to latest or similar.
This allows syncing to a historical manifest in git log,
that does not have a branch, as well as when integrating
something together that has not been pushed upstream yet.
Changes can also exist locally on a manifest that is
behind head, meaning not requiring rebase to latest.

This is most noticeable in the sync subcommand whose Execute func

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.

When repo syncs a manifest that utilizes multiple branches
in the same project, then the sync will use an extra
thread for each "duplicate". For example, if
the manifest includes the project "foo" and "bar"
twice, then "repo sync -jN" will fetch with N+2 threads.
This is caused by _FetchHelper() releasing the thread semaphore
object each time it's called, even though _FetchProjectList()
may call this function multiple times within the scope of a
single thread.
Fix by moving the thread semaphore release to
_FetchProjectList(), which is only called once per thread
instance.

When there are nested projects in a manifest, like on AOSP right now:
<project path="build" name="platform/build" />
<project path="build/blueprint" name="platform/build/blueprint" />
<project path="build/kati" name="platform/build/kati" />
<project path="build/soong" name="platform/build/soong" />
And the top "build" project is removed (or renamed to remove the
nesting), repo just wipes away everything under build/ and re-creates
the projects that are still there. But it only checks to see if the
build/ project is dirty, so if there are dirty files in a nested
project, they'll just be blown away, and a fresh worktree checked out.
Instead, behave similarly to how `git clean -dxf` behaves and preserve
any subdirectories that have git repositories in them. This isn't as
strict as git -- it does not check to see if the '.git' entry is a
readable gitdir, just whether an entry named '.git' exists.
If it encounters any errors removing files, we'll print them all out to
stderr and tell the user that we were unable to clean up the obsolete
project, that they should clean it up manually, then sync again.

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

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.

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.

(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.

Try to more accurately estimate which projects take the longest to
sync by keeping an exponentially weighted moving average (a=0.5) of
fetch times, rather than just recording the last observation. This

Some projects may consistently take longer to fetch than others, for
example a more active project may have many more Gerrit changes than a
less active project, which take longer to transfer. Use a simple
heuristic based on the last fetch time to fetch slower projects first,
so we do not tend to spend the end of the sync fetching a small number
of outliers.
This algorithm is probably not optimal, and due to inter-run latency
variance and Python thread scheduling, we may not even have good
estimates of a project sync time.

When using the --smart-sync or --smart-tag option, and the specified
manifest server is hosted on a server that requires authentication,
repo sync fails with the error: HTTP 401 Unauthorized.
Add support for getting the credentials from the .netrc file.
If a .netrc file exists in the user's home directory, and it contains
credentials for the hostname of the manifest server specified in the
manifest, use the credentials to authenticate with the manifest server
using the URL syntax extension for Basic Authentication:
http://user:password@host:port/path
Credentials from the .netrc file are only used if the manifest server
URL specified in the manifest does not already include credentials.

`R_HEADS` is imported twice, from both the git_refs and project
modules.
It is actually defined in git_refs, and in project it is imported
from there, so the import of `R_HEADS` from project in the sync
module is redundant. Remove it.
`HEAD` is imported from project, but like `R_HEADS` it is actually
defined in git_refs. Import it from git_refs instead.

When connecting to the manifest server, exceptions can occur but
are not caught, resulting in the repo sync exiting with a python
traceback.
Add handling of the following exceptions:
- IOError, which can be raised for example if the manifest server
URL is malformed.
- xmlrpclib.ProtocolError, which can be raised if the connection
to the manifest server fails with HTTP error.
- xmlrpclib.Fault, which can be raised if the RPC call fails for
some other reason.

The threaded 'repo sync' implementation would very often freeze the
process when interrupted by the user with Ctrl-C. The only solution
being to kill -9 the process explicitly from another terminal.
The reason for this is best explained here:
http://snakesthatbite.blogspot.fr/2010/09/cpython-threading-interrupting.html
This patch makes all helper sync threads 'daemon', which allows the
process to terminate immediately on Ctrl-C.
Note that this will forcefully kill all threads in case of interruption; this
is generally a bad thing, but:
1/ This is equivalent to calling kill -9 in another terminal, which
is the _only_ thing that can currently stop the process.
2/ There doesn't seem to be a way to tell the worker threads to
gently stop when they are in a blocking operation anyway (even
in the non-threaded case).
+ Do the same for "repo status -j<count>".

Allows specifying a list of groups with a -g argument to repo init.
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
of projects to sync.
If any non-inverted manifest groups are specified, the default label
is ignored.

This permits manifest authors to suggest a number of parallel
fetch operations against a remote server. For example, Gerrit
Code Review servers support queuing of requests and processes
them in first-in, first-out order. Running concurrent fetches
can utilize multiple CPUs on the Gerrit server, but will also
decrease overall operation latency by having the request put
into the queue ready to execute as soon as a CPU is free.

Each worker thread requires at least 3 file descriptors to run the
forked 'git fetch' child to operate against the local repository.
Mac OS X has the RLIMIT_NOFILE set to 256 by default, which means
a sync -j128 often fails when the workers run out of pipes within

Users may wind up with a lot of loose object content in projects they
don't frequently make changes in, but that are modified by others.
Since we bypass many git code paths that would have otherwise called
out to `git gc --auto`, its possible for these projects to have
their loose object database grow out of control. To help prevent
that, we now invoke it ourselves during the network half of sync.

This patch does two things for being compatibile with
those Python which are built without threading support:
1. As the Python document and Shawn suggested, import dummy_threading
when the threading is not available.
2. Reserve the single threaded code and make it default.
In cases the --jobs does not work properly with dummy_threading,
we still have a safe fallback.

This option allows the user to specify a manifest server to use when
syncing. This manifest server will provide a manifest pegging each
project to a known green build. This allows developers to work on a
known good tree that is known to build and pass tests, preventing
failed builds to hamper productivity.
The manifest used is not "sticky" so as to allow subsequent
'repo sync' calls to sync to the tip of the tree.

This bug happens when a project gets added to the manifest, and
then is renamed. Users who happened to have run "repo sync" after
the project was added but before the rename happened will try to
read the data from the old project, as the manifest was only updated
after all projects were updated successfully.
If a line is blank in project.list, its not a relevant project path,
so skip over it. Existing project.list files may have blank lines if
sync was run with no projects at all, and the file was created empty.

After a repo sync, some of the project paths might need
to be removed. This changes maintains a list of project
paths from the previous sync operation and compares.
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.

Its unlikely that a new version of repo will be delivered in any
given day, so we now check only once every 24 hours to see if repo
has been updated. This reduces the sync cost, as we no longer need
to contact the repo distribution servers every time we do a sync.
repo selfupdate can still be used to force a check.

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.

If a client was created with "repo init --mirror" then there are
no working directories present, and no files checked out. Using
a command like "repo status" in this context makes no sense, and
actually throws back a Pytyon traceback at the console when the
underlying commands fail out.
We now tag commands with the MirrorSafeCommand type if they are
able to be executed within a mirror directory safely. Using a
command in a mirror which lacks this base class results in a
useful error letting you know the command isn't supported.

The mirror option downloads a complete forrest (as described by the
manifest) and creates a replica of the remote repositories rather
than a client working directory. This permits other clients to
sync off the mirror site.
A mirror can be positioned in a "DMZ", where the mirror executes
"repo sync" to obtain changes from the external upstream and
clients inside the protected zone operate off the mirror only,
and therefore do not require direct git:// access to the external
upstream repositories.

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.
