CONTRIBUTING.md

+Contributing to Weston
+=======================
+
+Sending patches
+---------------
+
+Patches should be sent via
+[GitLab merge requests](https://docs.gitlab.com/ce/gitlab-basics/add-merge-request.html).
+Weston is
+[hosted on freedesktop.org's GitLab](https://gitlab.freedesktop.org/wayland/weston/):
+in order to submit code, you should create an account on this GitLab instance,
+fork the core Weston repository, push your changes to a branch in your new
+repository, and then submit these patches for review through a merge request.
+
+Weston formerly accepted patches via `git-send-email`, sent to
+**wayland-devel@lists.freedesktop.org**; these were
+[tracked using Patchwork](https://patchwork.freedesktop.org/projects/wayland/).
+Some old patches continue to be sent this way, and we may accept small new
+patches sent to the list, but please send all new patches through GitLab merge
+requests.
+
+Formatting and separating commits
+---------------------------------
+
+Unlike many projects using GitHub and GitLab, Weston has a
+[linear, 'recipe' style history](http://www.bitsnbites.eu/git-history-work-log-vs-recipe/).
+This means that every commit should be small, digestible, stand-alone, and
+functional. Rather than a purely chronological commit history like this:
+
+    doc: final docs for view transforms
+    fix tests when disabled, redo broken doc formatting
+    better transformed-view iteration (thanks Hannah!)
+    try to catch more cases in tests
+    tests: add new spline test
+    fix compilation on splines
+    doc: notes on reticulating splines
+    compositor: add spline reticulation for view transforms
+
+we aim to have a clean history which only reflects the final state, broken up
+into functional groupings:
+
+    compositor: add spline reticulation for view transforms
+    compositor: new iterator for view transforms
+    tests: add view-transform correctness tests
+    doc: fix Doxygen formatting for view transforms
+
+This ensures that the final patch series only contains the final state,
+without the changes and missteps taken along the development process.
+
+The first line of a commit message should contain a prefix indicating
+what part is affected by the patch followed by one sentence that
+describes the change. For examples:
+
+    compositor-drm: Support modifiers for drm_fb
+
+and
+
+    input: do not forward unmatched touch-ups
+
+If in doubt what prefix to use, look at other commits that change the
+same file(s) as the patch being sent.
+
+The body of the commit message should describe what the patch changes
+and why, and also note any particular side effects. This shouldn't be
+empty on most of the cases. It shouldn't take a lot of effort to write
+a commit message for an obvious change, so an empty commit message
+body is only acceptable if the questions "What?" and "Why?" are already
+answered on the one-line summary.
+
+The lines of the commit message should have at most 76 characters, to
+cope with the way git log presents them.
+
+See [notes on commit messages] for a recommended reading on writing commit
+messages.
+
+Your patches should also include a Signed-off-by line with your name and
+email address.  If you're not the patch's original author, you should
+also gather S-o-b's by them (and/or whomever gave the patch to you.) The
+significance of this is that it certifies that you created the patch,
+that it was created under an appropriate open source license, or
+provided to you under those terms.  This lets us indicate a chain of
+responsibility for the copyright status of the code.
+
+We won't reject patches that lack S-o-b, but it is strongly recommended.
+
+When you re-send patches, revised or not, it would be very good to document the
+changes compared to the previous revision in the commit message and/or the
+merge request. If you have already received Reviewed-by or Acked-by tags, you
+should evaluate whether they still apply and include them in the respective
+commit messages. Otherwise the tags may be lost, reviewers miss the credit they
+deserve, and the patches may cause redundant review effort.
+
+
+Tracking patches and following up
+---------------------------------
+
+Once submitted to GitLab, your patches will be reviewed by the Weston
+development team on GitLab. Review may be entirely positive and result in your
+code landing instantly, in which case, great! You're done. However, we may ask
+you to make some revisions: fixing some bugs we've noticed, working to a
+slightly different design, or adding documentation and tests.
+
+If you do get asked to revise the patches, please bear in mind the notes above.
+You should use `git rebase -i` to make revisions, so that your patches follow
+the clear linear split documented above. Following that split makes it easier
+for reviewers to understand your work, and to verify that the code you're
+submitting is correct.
+
+A common request is to split single large patch into multiple patches. This can
+happen, for example, if when adding a new feature you notice a bug in Weston's
+core which you need to fix to progress. Separating these changes into separate
+commits will allow us to verify and land the bugfix quickly, pushing part of
+your work for the good of everyone, whilst revision and discussion continues on
+the larger feature part. It also allows us to direct you towards reviewers who
+best understand the different areas you are working on.
+
+When you have made any requested changes, please rebase the commits, verify
+that they still individually look good, then force-push your new branch to
+GitLab. This will update the merge request and notify everyone subscribed to
+your merge request, so they can review it again.
+
+There are also
+[many GitLab CLI clients](https://about.gitlab.com/applications/#cli-clients),
+if you prefer to avoid the web interface. It may be difficult to follow review
+comments without using the web interface though, so we do recommend using this
+to go through the review process, even if you use other clients to track the
+list of available patches.
+
+
+Coding style
+------------
+
+You should follow the style of the file you're editing. In general, we
+try to follow the rules below.
+
+**Note: this file uses spaces due to markdown rendering issues for tabs.
+  Code must be indented using tabs.**
+
+- indent with tabs, and a tab is always 8 characters wide
+- opening braces are on the same line as the if statement;
+- no braces in an if-body with just one statement;
+- if one of the branches of an if-else condition has braces, then the
+  other branch should also have braces;
+- there is always an empty line between variable declarations and the
+  code;
+
+```c
+static int
+my_function(void)
+{
+        int a = 0;
+
+        if (a)
+                b();
+        else
+                c();
+
+        if (a) {
+                b();
+                c();
+        } else {
+                d();
+        }
+}
+```
+
+- lines should be less than 80 characters wide;
+- when breaking lines with functions calls, the parameters are aligned
+  with the opening parentheses;
+- when assigning a variable with the result of a function call, if the
+  line would be longer we break it around the equal '=' sign if it makes
+  sense;
+
+```c
+        long_variable_name =
+                function_with_a_really_long_name(parameter1, parameter2,
+                                                 parameter3, parameter4);
+
+        x = function_with_a_really_long_name(parameter1, parameter2,
+                                             parameter3, parameter4);
+```
+
+Conduct
+=======
+
+As a freedesktop.org project, Wayland follows the Contributor Covenant,
+found at:
+https://www.freedesktop.org/wiki/CodeOfConduct
+
+Please conduct yourself in a respectful and civilised manner when
+interacting with community members on mailing lists, IRC, or bug
+trackers. The community represents the project as a whole, and abusive
+or bullying behaviour is not tolerated by the project.
+
+
+Licensing
+=========
+
+Weston is licensed with the intention to be usable anywhere X.org is.
+Originally, X.org was covered under the MIT X11 license, but changed to
+the MIT Expat license.  Similarly, Weston was covered initially as MIT
+X11 licensed, but changed to the MIT Expat license, following in X.org's
+footsteps.  Other than wording, the two licenses are substantially the
+same, with the exception of a no-advertising clause in X11 not included
+in Expat.
+
+New source code files should specify the MIT Expat license in their
+boilerplate, as part of the copyright statement.
+
+
+Review
+======
+
+All patches, even trivial ones, require at least one positive review
+(Reviewed-by). Additionally, if no Reviewed-by's have been given by
+people with commit access, there needs to be at least one Acked-by from
+someone with commit access. A person with commit access is expected to be
+able to evaluate the patch with respect to the project scope and architecture.
+
+The below review guidelines are intended to be interpreted in spirit, not by
+the letter. There may be circumstances where some guidelines are better
+ignored. We rely very much on the judgement of reviewers and commit rights
+holders.
+
+During review, the following matters should be checked:
+
+- The commit message explains why the change is being made.
+
+- The code fits the project's scope.
+
+- The code license is the same MIT licence the project generally uses.
+
+- Stable ABI or API is not broken.
+
+- Stable ABI or API additions must be justified by actual use cases, not only
+by speculation. They must also be documented, and it is strongly recommended to
+include tests excercising the additions in the test suite.
+
+- The code fits the existing software architecture, e.g. no layering
+violations.
+
+- The code is correct and does not introduce new failures for existing users,
+does not add new corner-case bugs, and does not introduce new compiler
+warnings.
+
+- The patch does what it says in the commit message and changes nothing else.
+
+- The patch is a single logical change. If the commit message addresses
+multiple points, it is a hint that the commit might need splitting up.
+
+- A bug fix should target the underlying root cause instead of hiding symptoms.
+If a complete fix is not practical, partial fixes are acceptable if they come
+with code comments and filed Gitlab issues for the remaining bugs.
+
+- The bug root cause rule applies to external software components as well, e.g.
+do not work around kernel driver issues in userspace.
+
+- The test suite passes.
+
+- The code does not depend on API or ABI which has no working free open source
+implementation.
+
+- The code is not dead or untestable. E.g. if there are no free open source
+software users for it then it is effectively dead code.
+
+- The code is written to be easy to understand, or if code cannot be clear
+enough on its own there are code comments to explain it.
+
+- The code is minimal, i.e. prefer refactor and re-use when possible unless
+clarity suffers.
+
+- The code adheres to the style guidelines.
+
+- In a patch series, every intermediate step adheres to the above guidelines.
+
+
+Commit rights
+=============
+
+Commit rights will be granted to anyone who requests them and fulfills the
+below criteria:
+
+- Submitted some (10 as a rule of thumb) non-trivial (not just simple
+  spelling fixes and whitespace adjustment) patches that have been merged
+  already.
+
+- Are actively participating in public discussions about their work (on the
+  mailing list or IRC). This should not be interpreted as a requirement to
+  review other peoples patches but just make sure that patch submission isn't
+  one-way communication. Cross-review is still highly encouraged.
+
+- Will be regularly contributing further patches. This includes regular
+  contributors to other parts of the open source graphics stack who only
+  do the occasional development in this project.
+
+- Agrees to use their commit rights in accordance with the documented merge
+  criteria, tools, and processes.
+
+To apply for commit rights, create a new issue in gitlab for the respective
+project and give it the "accounts" label.
+
+Committers are encouraged to request their commit rights get removed when they
+no longer contribute to the project. Commit rights will be reinstated when they
+come back to the project.
+
+Maintainers and committers should encourage contributors to request commit
+rights, especially junior contributors tend to underestimate their skills.
+
+
+Stabilising for releases
+========================
+
+A release cycle ends with a stable release which also starts a new cycle and
+lifts any code freezes. Gradual code freezing towards a stable release starts
+with an alpha release. The release stages of a cycle are:
+
+- **Alpha release**:
+    Signified by version number #.#.91.
+    Major features must have landed before this. Major features include
+    invasive code motion and refactoring, high risk changes, and new stable
+    library ABI.
+
+- **Beta release**:
+    Signified by version number #.#.92.
+    Minor features must have landed before this. Minor features include all
+    new features that are not major, low risk changes, clean-ups, and
+    documentation. Stable ABI that was new in the alpha release can be removed
+    before a beta release if necessary.
+
+- **Release candidates (RC)**:
+    Signified by version number #.#.93 and up to #.#.99.
+    Bug fixes that are not release critical must have landed before this.
+    Release critical bug fixes can still be landed after this, but they may
+    call for another RC.
+
+- **Stable release**:
+    Signified by version number #.#.0.
+    Ideally no changes since the last RC.
+
+Mind that version #.#.90 is never released. It is used during development when
+no code freeze is in effect. Stable branches and point releases are not covered
+by the above.

-Weston is the reference implementation of a Wayland compositor, and a
-useful compositor in its own right.  Weston has various backends that
-lets it run on Linux kernel modesetting and evdev input as well as
-under X11.  Weston ships with a few example clients, from simple
-clients that demonstrate certain aspects of the protocol to more
-complete clients and a simplistic toolkit.  There is also a quite
-capable terminal emulator (weston-terminal) and an toy/example desktop
-shell.  Finally, weston also provides integration with the Xorg server
-and can pull X clients into the Wayland desktop and act as an X window
-manager.
-
-Refer to http://wayland.freedesktop.org/building.html for building
-weston and its dependencies.
-
-The test suite can be invoked via `make check`; see
-http://wayland.freedesktop.org/testing.html for additional details.
-
-Developer documentation can be built via `make doc`. Output will be in
-the build root under

+![screenshot of skeletal Weston desktop](doc/wayland-screenshot.jpg)
+
+Weston is the reference implementation of a Wayland compositor, as well as a
+useful environment in and of itself.
+
+Out of the box, Weston provides a very basic desktop, or a full-featured
+environment for non-desktop uses such as automotive, embedded, in-flight,
+industrial, kiosks, set-top boxes and TVs. It also provides a library allowing
+other projects to build their own full-featured environments on top of Weston's
+core.
+
+The core focus of Weston is correctness and reliability. Weston aims to be lean
+and fast, but more importantly, to be predictable. Whilst Weston does have known
+bugs and shortcomings, we avoid unknown or variable behaviour as much as
+possible, including variable performance such as occasional spikes in frame
+display time.
+
+A small suite of example or demo clients are also provided: though they can be
+useful in themselves, their main purpose is to be an example or test case for
+others building compositors or clients.
+
+If you are after a more mainline desktop experience, the
+[GNOME](https://www.gnome.org) and [KDE](https://www.kde.org) projects provide
+full-featured desktop environments built on the Wayland protocol. Many other
+projects also exist providing Wayland clients and desktop environments: you are
+not limited to just what you can find in Weston.
+
+Reporting issues and contributing
+=================================
+
+Weston's development is
+[hosted on freedesktop.org GitLab](https://gitlab.freedesktop.org/wayland/weston/).
+Please also see [the contributing document](CONTRIBUTING.md), which details how
+to make code or non-technical contributions to Weston.
+
+Building Weston
+===============
+
+Weston is built using autotools, with `autogen.sh` and `make`. It often depends
+on the current release versions of
+[Wayland](https://gitlab.freedesktop.org/wayland/wayland) and
+[wayland-protocols](https://cgit.freedesktop.org/wayland/wayland-protocols).
+
+Every push to the Weston master repository and its forks is built using GitLab
+CI. [Reading the configuration](.gitlab-ci.yml) may provide a useful example of
+how to build and install Weston.
+
+More [detailed documentation on building Weston](https://wayland.freedesktop.org/building.html)
+is available on the Wayland site. There are also more details on
+[how to run and write tests](https://wayland.freedesktop.org/testing.html).
+
+Running Weston
+==============
+
+Once Weston is installed, most users can simply run it by typing `weston`. This
+will launch Weston inside whatever environment you launch it from: when launched
+from a text console, it will take over that console. When launched from inside
+an existing Wayland or X11 session, it will start a 'nested' instance of Weston
+inside a window in that session.
+
+Help is available by running `weston --help`, or `man weston`, which will list
+the available configuration options and display backends. It can also be
+configured through a file on disk; more information on this can be found through
+`man weston.ini`.
+
+In some special cases, such as when running remotely or without logind's session
+control, Weston may not be able to run directly from a text console. In these
+situations, you can instead execute the `weston-launch` helper, which will gain
+privileged access to input and output devices by running as root, then granting
+access to the main Weston binary running as your user. Running Weston this way
+is not recommended unless necessary.
