+# repo
+
+Repo is a tool built on top of Git.  Repo helps manage many Git repositories,
+does the uploads to revision control systems, and automates parts of the
+development workflow.  Repo is not meant to replace Git, only to make it
+easier to work with Git.  The repo command is an executable Python script
+that you can put anywhere in your path.

+# Short Version
+
+ - Make small logical changes.
+ - Provide a meaningful commit message.
+ - Check for coding errors and style nits with pyflakes and flake8
+ - Make sure all code is under the Apache License, 2.0.
+ - Publish your changes for review.
+ - Make corrections if requested.

+
+
+# Long Version
+
+I wanted a file describing how to submit patches for repo,
+so I started with the one found in the core Git distribution
+(Documentation/SubmittingPatches), which itself was based on the
+patch submission guidelines for the Linux kernel.
+
+However there are some differences, so please review and familiarize
+yourself with the following relevant bits.
+
+
+## Make separate commits for logically separate changes.
+
+Unless your patch is really trivial, you should not be sending
+out a patch that was generated between your working tree and your
+commit head.  Instead, always make a commit with complete commit
+message and generate a series of patches from your repository.
+It is a good discipline.
+
+Describe the technical detail of the change(s).
+
+If your description starts to get too long, that's a sign that you
+probably need to split up your commit to finer grained pieces.
+
+
+## Check for coding errors and style nits with pyflakes and flake8
+
+### Coding errors
+
+Run `pyflakes` on changed modules:
+
+    pyflakes file.py
+
+Ideally there should be no new errors or warnings introduced.
+
+### Style violations
+
+Run `flake8` on changes modules:
+
+    flake8 file.py
+
+Note that repo generally follows [Google's python style guide]
+(https://google.github.io/styleguide/pyguide.html) rather than [PEP 8]
+(https://www.python.org/dev/peps/pep-0008/), so it's possible that
+the output of `flake8` will be quite noisy. It's not mandatory to
+avoid all warnings, but at least the maximum line length should be
+followed.
+
+If there are many occurrences of the same warning that cannot be
+avoided without going against the Google style guide, these may be
+suppressed in the included `.flake8` file.
+
+## Check the license
+
+repo is licensed under the Apache License, 2.0.
+
+Because of this licensing model *every* file within the project
+*must* list the license that covers it in the header of the file.
+Any new contributions to an existing file *must* be submitted under
+the current license of that file.  Any new files *must* clearly
+indicate which license they are provided under in the file header.
+
+Please verify that you are legally allowed and willing to submit your
+changes under the license covering each file *prior* to submitting
+your patch.  It is virtually impossible to remove a patch once it
+has been applied and pushed out.
+
+
+## Sending your patches.
+
+Do not email your patches to anyone.
+
+Instead, login to the Gerrit Code Review tool at:
+
+  https://gerrit-review.googlesource.com/
+
+Ensure you have completed one of the necessary contributor
+agreements, providing documentation to the project maintainers that
+they have right to redistribute your work under the Apache License:
+
+  https://gerrit-review.googlesource.com/#/settings/agreements
+
+Ensure you have obtained an HTTP password to authenticate:
+
+  https://gerrit-review.googlesource.com/new-password
+
+Ensure that you have the local commit hook installed to automatically
+add a ChangeId to your commits:
+
+    curl -Lo `git rev-parse --git-dir`/hooks/commit-msg https://gerrit-review.googlesource.com/tools/hooks/commit-msg
+    chmod +x `git rev-parse --git-dir`/hooks/commit-msg
+
+If you have already committed your changes you will need to amend the commit
+to get the ChangeId added.
+
+    git commit --amend
+
+Push your patches over HTTPS to the review server, possibly through
+a remembered remote to make this easier in the future:
+
+    git config remote.review.url https://gerrit-review.googlesource.com/git-repo
+    git config remote.review.push HEAD:refs/for/master
+
+    git push review
+
+You will be automatically emailed a copy of your commits, and any
+comments made by the project maintainers.
+
+
+## Make changes if requested
+
+The project maintainer who reviews your changes might request changes to your
+commit. If you make the requested changes you will need to amend your commit
+and push it to the review server again.
+
+
+## Verify your changes on gerrit
+
+After you receive a Code-Review+2 from the maintainer, select the Verified
+button on the gerrit page for the change. This verifies that you have tested
+your changes and notifies the maintainer that they are ready to be submitted.
+The maintainer will then submit your changes to the repository.

+# repo Manifest Format
+
+A repo manifest describes the structure of a repo client; that is
+the directories that are visible and where they should be obtained
+from with git.
+
+The basic structure of a manifest is a bare Git repository holding
+a single `default.xml` XML file in the top level directory.
+
+Manifests are inherently version controlled, since they are kept
+within a Git repository.  Updates to manifests are automatically
+obtained by clients during `repo sync`.
+
+[TOC]
+
+
+## XML File Format
+
+A manifest XML file (e.g. `default.xml`) roughly conforms to the
+following DTD:
+
+```xml
+<!DOCTYPE manifest [
+  <!ELEMENT manifest (notice?,
+                      remote*,
+                      default?,

+
+A description of the elements and their attributes follows.
+
+
+### Element manifest
+
+The root element of the file.
+
+
+### Element remote
+
+One or more remote elements may be specified.  Each remote element
+specifies a Git URL shared by one or more projects and (optionally)
+the Gerrit review server those projects upload changes through.
+
+Attribute `name`: A short name unique to this manifest file.  The
+name specified here is used as the remote name in each project's
+.git/config, and is therefore automatically available to commands
+like `git fetch`, `git remote`, `git pull` and `git push`.
+
+Attribute `alias`: The alias, if specified, is used to override
+`name` to be set as the remote name in each project's .git/config.
+Its value can be duplicated while attribute `name` has to be unique
+in the manifest file. This helps each project to be able to have
+same remote name which actually points to different remote url.
+
+Attribute `fetch`: The Git URL prefix for all projects which use
+this remote.  Each project's name is appended to this prefix to
+form the actual URL used to clone the project.
+
+Attribute `pushurl`: The Git "push" URL prefix for all projects
+which use this remote.  Each project's name is appended to this
+prefix to form the actual URL used to "git push" the project.
+This attribute is optional; if not specified then "git push"
+will use the same URL as the `fetch` attribute.
+
+Attribute `review`: Hostname of the Gerrit server where reviews
+are uploaded to by `repo upload`.  This attribute is optional;
+if not specified then `repo upload` will not function.
+
+Attribute `revision`: Name of a Git branch (e.g. `master` or
+`refs/heads/master`). Remotes with their own revision will override
+the default revision.
+
+### Element default
+
+At most one default element may be specified.  Its remote and
+revision attributes are used when a project element does not
+specify its own remote or revision attribute.
+
+Attribute `remote`: Name of a previously defined remote element.
+Project elements lacking a remote attribute of their own will use
+this remote.
+
+Attribute `revision`: Name of a Git branch (e.g. `master` or
+`refs/heads/master`).  Project elements lacking their own
+revision attribute will use this revision.
+
+Attribute `dest-branch`: Name of a Git branch (e.g. `master`).
+Project elements not setting their own `dest-branch` will inherit
+this value. If this value is not set, projects will use `revision`
+by default instead.
+
+Attribute `upstream`: Name of the Git ref in which a sha1
+can be found.  Used when syncing a revision locked manifest in
+-c mode to avoid having to sync the entire ref space. Project elements
+not setting their own `upstream` will inherit this value.
+
+Attribute `sync-j`: Number of parallel jobs to use when synching.
+
+Attribute `sync-c`: Set to true to only sync the given Git
+branch (specified in the `revision` attribute) rather than the
+whole ref space.  Project elements lacking a sync-c element of
+their own will use this value.
+
+Attribute `sync-s`: Set to true to also sync sub-projects.
+
+Attribute `sync-tags`: Set to false to only sync the given Git
+branch (specified in the `revision` attribute) rather than
+the other ref tags.
+
+
+### Element manifest-server
+
+At most one manifest-server may be specified. The url attribute
+is used to specify the URL of a manifest server, which is an
+XML RPC service.
+
+The manifest server should implement the following RPC methods:
+
+    GetApprovedManifest(branch, target)
+
+Return a manifest in which each project is pegged to a known good revision
+for the current branch and target. This is used by repo sync when the
+--smart-sync option is given.
+
+The target to use is defined by environment variables TARGET_PRODUCT
+and TARGET_BUILD_VARIANT. These variables are used to create a string
+of the form $TARGET_PRODUCT-$TARGET_BUILD_VARIANT, e.g. passion-userdebug.
+If one of those variables or both are not present, the program will call
+GetApprovedManifest without the target parameter and the manifest server
+should choose a reasonable default target.
+
+    GetManifest(tag)
+
+Return a manifest in which each project is pegged to the revision at
+the specified tag. This is used by repo sync when the --smart-tag option
+is given.
+
+
+### Element project
+
+One or more project elements may be specified.  Each element
+describes a single Git repository to be cloned into the repo
+client workspace.  You may specify Git-submodules by creating a
+nested project.  Git-submodules will be automatically
+recognized and inherit their parent's attributes, but those
+may be overridden by an explicitly specified project element.
+
+Attribute `name`: A unique name for this project.  The project's
+name is appended onto its remote's fetch URL to generate the actual
+URL to configure the Git remote with.  The URL gets formed as:
+
+    ${remote_fetch}/${project_name}.git
+
+where ${remote_fetch} is the remote's fetch attribute and
+${project_name} is the project's name attribute.  The suffix ".git"
+is always appended as repo assumes the upstream is a forest of
+bare Git repositories.  If the project has a parent element, its
+name will be prefixed by the parent's.
+
+The project name must match the name Gerrit knows, if Gerrit is
+being used for code reviews.
+
+Attribute `path`: An optional path relative to the top directory
+of the repo client where the Git working directory for this project
+should be placed.  If not supplied the project name is used.
+If the project has a parent element, its path will be prefixed
+by the parent's.
+
+Attribute `remote`: Name of a previously defined remote element.
+If not supplied the remote given by the default element is used.
+
+Attribute `revision`: Name of the Git branch the manifest wants
+to track for this project.  Names can be relative to refs/heads
+(e.g. just "master") or absolute (e.g. "refs/heads/master").
+Tags and/or explicit SHA-1s should work in theory, but have not
+been extensively tested.  If not supplied the revision given by
+the remote element is used if applicable, else the default
+element is used.
+
+Attribute `dest-branch`: Name of a Git branch (e.g. `master`).
+When using `repo upload`, changes will be submitted for code
+review on this branch. If unspecified both here and in the
+default element, `revision` is used instead.
+
+Attribute `groups`: List of groups to which this project belongs,
+whitespace or comma separated.  All projects belong to the group
+"all", and each project automatically belongs to a group of
+its name:`name` and path:`path`.  E.g. for
+<project name="monkeys" path="barrel-of"/>, that project
+definition is implicitly in the following manifest groups:
+default, name:monkeys, and path:barrel-of.  If you place a project in the
+group "notdefault", it will not be automatically downloaded by repo.
+If the project has a parent element, the `name` and `path` here
+are the prefixed ones.
+
+Attribute `sync-c`: Set to true to only sync the given Git
+branch (specified in the `revision` attribute) rather than the
+whole ref space.
+
+Attribute `sync-s`: Set to true to also sync sub-projects.
+
+Attribute `upstream`: Name of the Git ref in which a sha1
+can be found.  Used when syncing a revision locked manifest in
+-c mode to avoid having to sync the entire ref space.
+
+Attribute `clone-depth`: Set the depth to use when fetching this
+project.  If specified, this value will override any value given
+to repo init with the --depth option on the command line.
+
+Attribute `force-path`: Set to true to force this project to create the
+local mirror repository according to its `path` attribute (if supplied)
+rather than the `name` attribute.  This attribute only applies to the
+local mirrors syncing, it will be ignored when syncing the projects in a
+client working directory.
+
+### Element extend-project
+
+Modify the attributes of the named project.
+
+This element is mostly useful in a local manifest file, to modify the
+attributes of an existing project without completely replacing the
+existing project definition.  This makes the local manifest more robust
+against changes to the original manifest.
+
+Attribute `path`: If specified, limit the change to projects checked out
+at the specified path, rather than all projects with the given name.
+
+Attribute `groups`: List of additional groups to which this project
+belongs.  Same syntax as the corresponding element of `project`.
+
+Attribute `revision`: If specified, overrides the revision of the original
+project.  Same syntax as the corresponding element of `project`.
+
+### Element annotation
+
+Zero or more annotation elements may be specified as children of a
+project element. Each element describes a name-value pair that will be
+exported into each project's environment during a 'forall' command,
+prefixed with REPO__.  In addition, there is an optional attribute
+"keep" which accepts the case insensitive values "true" (default) or
+"false".  This attribute determines whether or not the annotation will
+be kept when exported with the manifest subcommand.
+
+### Element copyfile
+
+Zero or more copyfile elements may be specified as children of a
+project element. Each element describes a src-dest pair of files;
+the "src" file will be copied to the "dest" place during `repo sync`
+command.
+"src" is project relative, "dest" is relative to the top of the tree.
+
+### Element linkfile
+
+It's just like copyfile and runs at the same time as copyfile but
+instead of copying it creates a symlink.
+
+### Element remove-project
+
+Deletes the named project from the internal manifest table, possibly
+allowing a subsequent project element in the same manifest file to
+replace the project with a different source.
+
+This element is mostly useful in a local manifest file, where
+the user can remove a project, and possibly replace it with their
+own definition.
+
+### Element include
+
+This element provides the capability of including another manifest
+file into the originating manifest.  Normal rules apply for the
+target manifest to include - it must be a usable manifest on its own.
+
+Attribute `name`: the manifest to include, specified relative to
+the manifest repository's root.
+
+
+## Local Manifests
+
+Additional remotes and projects may be added through local manifest
+files stored in `$TOP_DIR/.repo/local_manifests/*.xml`.
+
+For example:
+
+    $ ls .repo/local_manifests
+    local_manifest.xml
+    another_local_manifest.xml
+
+    $ cat .repo/local_manifests/local_manifest.xml
+    <?xml version="1.0" encoding="UTF-8"?>
+    <manifest>
+      <project path="manifest"
+               name="tools/manifest" />
+      <project path="platform-manifest"
+               name="platform/manifest" />
+    </manifest>
+
+Users may add projects to the local manifest(s) prior to a `repo sync`
+invocation, instructing repo to automatically download and manage
+these extra projects.
+
+Manifest files stored in `$TOP_DIR/.repo/local_manifests/*.xml` will
+be loaded in alphabetical order.
+
+Additional remotes and projects may also be added through a local
+manifest, stored in `$TOP_DIR/.repo/local_manifest.xml`. This method
+is deprecated in favor of using multiple manifest files as mentioned
+above.
+
+If `$TOP_DIR/.repo/local_manifest.xml` exists, it will be loaded before
+any manifest files stored in `$TOP_DIR/.repo/local_manifests/*.xml`.

+# repo hooks
+
+[TOC]
+
+Repo provides a mechanism to hook specific stages of the runtime with custom
+python modules.  All the hooks live in one git project which is checked out by
+the manifest (specified during `repo init`), and the manifest itself defines
+which hooks are registered.
+
+These are useful to run linters, check formatting, and run quick unittests
+before allowing a step to proceed (e.g. before uploading a commit to Gerrit).
+
+A complete example can be found in the Android project.  It can be easily
+re-used by any repo based project and is not specific to Android.<br>
+https://android.googlesource.com/platform/tools/repohooks
+
+## Approvals
+
+When a hook is processed the first time, the user is prompted for approval.
+We don't want to execute arbitrary code without explicit consent.  For manifests
+fetched via secure protocols (e.g. https://), the user is prompted once.  For
+insecure protocols (e.g. http://), the user is prompted whenever the registered
+repohooks project is updated and a hook is triggered.
+
+## Manifest Settings
+
+For the full syntax, see the [repo manifest format](./manifest-format.md).
+
+Here's a short example from
+[Android](https://android.googlesource.com/platform/manifest/+/master/default.xml).
+The `<project>` line checks out the repohooks git repo to the local
+`tools/repohooks/` path.  The `<repo-hooks>` line says to look in the project
+with the name `platform/tools/repohooks` for hooks to run during the
+`pre-upload` phase.
+
+```xml
+<project path="tools/repohooks" name="platform/tools/repohooks" />
+<repo-hooks in-project="platform/tools/repohooks" enabled-list="pre-upload" />
+```
+
+## Source Layout
+
+The repohooks git repo should have a python file with the same name as the hook.
+So if you want to support the `pre-upload` hook, you'll need to create a file
+named `pre-upload.py`.  Repo will dynamically load that module when processing
+the hook and then call the `main` function in it.
+
+Hooks should have their `main` accept `**kwargs` for future compatibility.
+
+## Runtime
+
+Hook return values are ignored.
+
+Any uncaught exceptions from the hook will cause the step to fail.  This is
+intended as a fallback safety check though rather than the normal flow.  If
+you want your hook to trigger a failure, it should call `sys.exit()` (after
+displaying relevant diagnostics).
+
+Output (stdout & stderr) are not filtered in any way.  Hooks should generally
+not be too verbose.  A short summary is nice, and some status information when
+long running operations occur, but long/verbose output should be used only if
+the hook ultimately fails.
+
+The hook runs from the top level of the repo client where the operation is
+started.
+For example, if the repo client is under `~/tree/`, then that is where the hook
+runs, even if you ran repo in a git repository at `~/tree/src/foo/`, or in a
+subdirectory of that git repository in `~/tree/src/foo/bar/`.
+Hooks frequently start off by doing a `os.chdir` to the specific project they're
+called on (see below) and then changing back to the original dir when they're
+finished.
+
+Python's `sys.path` is modified so that the top of repohooks directory comes
+first.  This should help simplify the hook logic to easily allow importing of
+local modules.
+
+Repo does not modify the state of the git checkout.  This means that the hooks
+might be running in a dirty git repo with many commits and checked out to the
+latest one.  If the hook wants to operate on specific git commits, it needs to
+manually discover the list of pending commits, extract the diff/commit, and
+then check it directly.  Hooks should not normally modify the active git repo
+(such as checking out a specific commit to run checks) without first prompting
+the user.  Although user interaction is discouraged in the common case, it can
+be useful when deploying automatic fixes.
+
+## Hooks
+
+Here are all the points available for hooking.
+
+### pre-upload
+
+This hook runs when people run `repo upload`.
+
+The `pre-upload.py` file should be defined like:
+
+```py
+def main(project_list, worktree_list=None, **kwargs):
+    """Main function invoked directly by repo.
+
+    We must use the name "main" as that is what repo requires.
+
+    Args:
+      project_list: List of projects to run on.
+      worktree_list: A list of directories.  It should be the same length as
+          project_list, so that each entry in project_list matches with a
+          directory in worktree_list.  If None, we will attempt to calculate
+          the directories automatically.
+      kwargs: Leave this here for forward-compatibility.

 Executes the same shell command in each project.
 
-Environment
------------
-pwd is the project's working directory.
+The -r option allows running the command only on projects matching
+regex or wildcard expression.
+
+# Output Formatting
+
+The -p option causes '%prog' to bind pipes to the command's stdin,
+stdout and stderr streams, and pipe all output into a continuous
+stream that is displayed in a single pager session.  Project headings
+are inserted before the output of each command is displayed.  If the
+command produces no output in a project, no heading is displayed.
+
+The formatting convention used by -p is very suitable for some
+types of searching, e.g. `repo forall -p -c git log -SFoo` will
+print all commits that add or remove references to Foo.
+
+The -v option causes '%prog' to display stderr messages if a
+command produces output only on stderr.  Normally the -p option
+causes command output to be suppressed until the command produces
+at least one byte of output on stdout.
+
+# Environment
+
+pwd is the project's working directory.  If the current client is
+a mirror client, then pwd is the Git repository.
 
 REPO_PROJECT is set to the unique name of the project.
 
+REPO_PATH is the path relative the the root of the client.
+
+REPO_REMOTE is the name of the remote system from the manifest.
+
+REPO_LREV is the name of the revision from the manifest, translated
+to a local tracking branch.  If you need to pass the manifest
+revision to a locally executed git command, use REPO_LREV.
+
+REPO_RREV is the name of the revision from the manifest, exactly
+as written in the manifest.
+
+REPO_COUNT is the total number of projects being iterated.
+
+REPO_I is the current (1-based) iteration count. Can be used in
+conjunction with REPO_COUNT to add a simple progress indicator to your
+command.
+
+REPO__* are any extra environment variables, specified by the
+"annotation" element under any project element.  This can be useful
+for differentiating trees based on user-specific criteria, or simply
+annotating tree details.
+
 shell positional arguments ($1, $2, .., $#) are set to any arguments
 following <command>.
 
-stdin, stdout, stderr are inherited from the terminal and are
-not redirected.
+Example: to list projects:
+
+  %prog% forall -c 'echo $REPO_PROJECT'
+
+Notice that $REPO_PROJECT is quoted to ensure it is expanded in
+the context of running <command> instead of in the calling shell.
+
+Unless -p is used, stdin, stdout, stderr are inherited from the
+terminal and are not redirected.
+
+If -e is used, when a command exits unsuccessfully, '%prog' will abort
+without iterating through the remaining projects.

+
+The -j/--jobs option can be used to run multiple status queries

+
+The -o/--orphans option can be used to show objects that are in

+if it is not known to repo.
+
+# Status Display
+
+The status display is organized into three columns of information,
+for example if the file 'subcmds/status.py' is modified in the

+The '%prog' command is used to send changes to the Gerrit Code
+Review system.  It searches for topic branches in local projects
+that have not yet been published for review.  If multiple topic
+branches are found, '%prog' opens an editor to allow the user to
+select which branches to upload.
+
+'%prog' searches for uploadable changes in all projects listed at
+the command line.  Projects can be specified either by name, or by
+a relative or absolute path to the project's local directory. If no
+projects are specified, '%prog' will search for uploadable changes
+in all projects listed in the manifest.
+
+If the --reviewers or --cc options are passed, those emails are
+added to the respective list of users, and emails are sent to any
+new users.  Users passed as --reviewers must already be registered
+with the code review system, or the upload will fail.
+
+# Configuration
+
+review.URL.autoupload:
+
+To disable the "Upload ... (y/N)?" prompt, you can set a per-project
+or global Git configuration option.  If review.URL.autoupload is set
+to "true" then repo will assume you always answer "y" at the prompt,
+and will not prompt you further.  If it is set to "false" then repo
+will assume you always answer "n", and will abort.
+
+review.URL.autoreviewer:
+
+To automatically append a user or mailing list to reviews, you can set
+a per-project or global Git option to do so.
+
+review.URL.autocopy:
+
+To automatically copy a user or mailing list to all uploaded reviews,
+you can set a per-project or global Git option to do so. Specifically,
+review.URL.autocopy can be set to a comma separated list of reviewers
+who you always want copied on all uploads with a non-empty --re
+argument.
+
+review.URL.username:
+
+Override the username used to connect to Gerrit Code Review.
+By default the local part of the email address is used.
+
+The URL must match the review URL listed in the manifest XML file,
+or in the .git/config within the project.  For example:
+
+  [remote "origin"]
+    url = git://git.example.com/project.git
+    review = http://review.example.com/
+
+  [review "http://review.example.com/"]
+    autoupload = true
+    autocopy = johndoe@company.com,my-team-alias@company.com
+
+review.URL.uploadtopic:
+
+To add a topic branch whenever uploading a commit, you can set a
+per-project or global Git option to do so. If review.URL.uploadtopic
+is set to "true" then repo will assume you always want the equivalent
+of the -t option to the repo command. If unset or set to "false" then
+repo will make use of only the command line option.
