SUBMITTING_PATCHES

@@ -0,0 +1,87 @@
+Short Version:
+
+ - Make small logical changes.
+ - Provide a meaningful commit message.
+ - Check for coding errors with pylint
+ - Make sure all code is under the Apache License, 2.0.
+ - Publish your changes for review:
+
+   git push https://gerrit-review.googlesource.com/git-repo HEAD:refs/for/master
+
+
+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:
+
+
+(1) 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.
+
+
+(2) Check for coding errors with pylint
+
+Run pylint on changed modules using the provided configuration:
+
+  pylint --rcfile=.pylintrc file.py
+
+
+(3) 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.
+
+
+(4) 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
+
+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.

+Additional remotes and projects may be added through local manifest
+files stored in `$TOP_DIR/.repo/local_manifests/*.xml`.

 invocation, instructing repo to automatically download and manage
 these extra projects.

-may support picking different revisions of a project, or deleting
-projects specified in the default manifest.
+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`.

 Executes the same shell command in each project.
 
+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.
+
+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.
+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.

+in order to scan multiple trees.  If the same file matches in more
+than one tree, only the first result is reported, prefixed by the
+revision name it was found under.
+
+Examples
+-------
+
+Look for a line that has '#define' and either 'MAX_PATH or 'PATH_MAX':
+
+  repo grep -e '#define' --and -\\( -e MAX_PATH -e PATH_MAX \\)
+
+Look for a line that has 'NODE' or 'Unexpected' in files that
+contain a line that matches both expressions:
+
+  repo grep --all-match -e NODE -e Unexpected

+'%prog' compares the working tree to the staging area (aka index),
+and the most recent commit on this branch (HEAD), in each project
+specified.  A summary is displayed, one line per file where there
+is a difference between these three states.
+
+The -j/--jobs option can be used to run multiple status queries
+in parallel.
+
+The -o/--orphans option can be used to show objects that are in
+the working directory, but not associated with a repo project.
+This includes unmanaged top-level files and directories, but also
+includes deeper items.  For example, if dir/subdir/proj1 and
+dir/subdir/proj2 are repo projects, dir/subdir/proj3 will be shown
+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
+project 'repo' on branch 'devwork':
+
+  project repo/                                   branch devwork
+   -m     subcmds/status.py
+
+The first column explains how the staging area (index) differs from
+the last commit (HEAD).  Its values are always displayed in upper
+case and have the following meanings:
+
+ -:  no difference
+ A:  added         (not in HEAD,     in index                     )
+ M:  modified      (    in HEAD,     in index, different content  )
+ D:  deleted       (    in HEAD, not in index                     )
+ R:  renamed       (not in HEAD,     in index, path changed       )
+ C:  copied        (not in HEAD,     in index, copied from another)
+ T:  mode changed  (    in HEAD,     in index, same content       )
+ U:  unmerged; conflict resolution required
+
+The second column explains how the working directory differs from
+the index.  Its values are always displayed in lower case and have
+the following meanings:
+
+ -:  new / unknown (not in index,     in work tree                )
+ m:  modified      (    in index,     in work tree, modified      )
+ d:  deleted       (    in index, not in work tree                )

 or absolute path to the project's local directory. If no projects
 are specified, '%prog' will synchronize all projects listed in
 the manifest.
+
+The -d/--detach option can be used to switch specified projects
+back to the manifest revision.  This option is especially helpful
+if the project is currently on a topic branch, but the manifest
+revision is temporarily needed.
+
+The -s/--smart-sync option can be used to sync to a known good
+build as specified by the manifest-server element in the current
+manifest. The -t/--smart-tag option is similar and allows you to
+specify a custom tag/label.
+
+The -u/--manifest-server-username and -p/--manifest-server-password
+options can be used to specify a username and password to authenticate
+with the manifest server when using the -s or -t option.
+
+If -u and -p are not specified when using the -s or -t option, '%prog'
+will attempt to read authentication credentials for the manifest server
+from the user's .netrc file.
+
+'%prog' will not use authentication credentials from -u/-p or .netrc
+if the manifest server specified in the manifest file already includes
+credentials.
+
+The -f/--force-broken option can be used to proceed with syncing
+other projects if a project sync fails.
+
+The --no-clone-bundle option disables any attempt to use
+$URL/clone.bundle to bootstrap a new Git repository from a
+resumeable bundle file on a content delivery network. This
+may be necessary if there are problems with the local Python
+HTTP client or proxy configuration, but the Git binary works.
+
+The --fetch-submodules option enables fetching Git submodules
+of a project from server.
+
+SSH Connections
+---------------
+
+If at least one project remote URL uses an SSH connection (ssh://,
+git+ssh://, or user@host:path syntax) repo will automatically
+enable the SSH ControlMaster option when connecting to that host.
+This feature permits other projects in the same '%prog' session to
+reuse the same SSH tunnel, saving connection setup overheads.
+
+To disable this behavior on UNIX platforms, set the GIT_SSH
+environment variable to 'ssh'.  For example:
+
+  export GIT_SSH=ssh
+  %prog
+
+Compatibility
+~~~~~~~~~~~~~
+
+This feature is automatically disabled on Windows, due to the lack
+of UNIX domain socket support.
+
+This feature is not compatible with url.insteadof rewrites in the
+user's ~/.gitconfig.  '%prog' is currently not able to perform the
+rewrite early enough to establish the ControlMaster tunnel.
+
+If the remote SSH daemon is Gerrit Code Review, version 2.0.10 or
+later is required to fix a server side protocol bug.

-The '%prog' command is used to send changes to the Gerrit code
-review system.  It searches for changes in local projects that do
-not yet exist in the corresponding remote repository.  If multiple
-changes are found, '%prog' opens an editor to allow the
-user to choose which change to upload.  After a successful upload,
-repo prints the URL for the change in the Gerrit code review system.
+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.
+'%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 to --reviewers must be already registered
+new users.  Users passed as --reviewers must already be registered
 with the code review system, or the upload will fail.
 
-If the --replace option is passed the user can designate which
-existing change(s) in Gerrit match up to the commits in the branch
-being uploaded.  For each matched pair of change,commit the commit
-will be added as a new patch set, completely replacing the set of
-files and description associated with the change in Gerrit.
+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.
