-# Sonata project contribution
-
-Thanks for your interest in Sonata projects!
-
-This document is about issues and pull requests.
-
-## Summary
-
-* [Issues](#issues)
-* [Pull Requests](#pull-requests)
-* [Code Reviews](#code-reviews)
-
-## Issues
-
-First, check if you are up to date: is your version still supported, and are
-you using the latest patch version?
-
-GitHub Issues is for **issues**, as opposed to question on how to use Sonata.
-If you are not sure this is a bug, or simply want to ask such a question,
-please post your question on [Stack Overflow](http://stackoverflow.com/questions/tagged/sonata),
-using the `sonata` tags.
-
-If you happen to find a bug, we kindly request you report it. However,
-before submitting it, please check the [project documentation available
-online](https://sonata-project.org/bundles/).
-
-Then, if it appears that it is indeed a real bug, you may report it using
-Github by following these points are taken care of:
-
-* Check if the bug is not already reported!
-* The title sums up the issue with clarity.
-* A description of the workflow needed to reproduce the bug. Please try to make
-  sentences, dumping an error message by itself is frowned upon.
-* If your issue is an error page, you must provide us with a stack trace. With
-  recent versions of Symfony, you can even get stack traces as plain text at the
-end of the page. Just look for "Stack Trace (Plain Text)", and copy/paste what
-you see. **Do not** make a screenshot of the stack trace, as screenshots are
-not indexed by search engines and will make it difficult for other people to
-find your bug report. If you have an issue when using the Symfony CLI,
-use the `-vvv` option to get a stack trace.
-* Screenshots should be considered additional data, and therefore, you should
-  always provide a textual description of the bug. It is strongly recommended
-to provide them when reporting UI-related bugs.
-* If you need to provide code, make sure you know how to get syntactic
-  coloration, in particular with [fenced code
-blocks](https://help.github.com/articles/creating-and-highlighting-code-blocks/).
-When you feel the code is to long, use external code pastebin like
-https://gist.github.com/ or http://hastebin.com/ . If this is not sufficient,
-just create a repository to show the issue.
-
-> _NOTE:_ Don't hesitate to give as much information as you can (OS, PHP
-> version, extensions...)
-
-## Pull Requests
-
-All the sonata team will be glad to review your code changes propositions! :smile:
-
-But please, read the following before.
-
-### The content
-
-#### Coding style
-
-Each project follows [PSR-1](http://www.php-fig.org/psr/psr-1/), [PSR-2](http://www.php-fig.org/psr/psr-2/)
-and [Symfony Coding Standards](http://symfony.com/doc/current/contributing/code/standards.html) for coding style,
-[PSR-4](http://www.php-fig.org/psr/psr-4/) for autoloading.
-
-Please [install PHP Coding Standard Fixer](http://cs.sensiolabs.org/#installation)
-and run this command before committing your modifications:
-
-```bash
-php-cs-fixer fix --verbose
-```
-
-#### The documentation
-
-The documentation is mostly written with the `rst` format, and can be found in the `Resources/doc` directory.
-You can test the doc rendering with the `make docs` command, but to do this, you will need [Sphinx][sphinx_install].
-Just like php dependencies can be managed with Composer, python dependencies can be managed with [pip][pip_install].
-To get sphinx, simply run the following command.
-
-```bash
-pip install --requirement {{ docs_path }}/requirements.txt --user
-```
-
-Some python binaries should be downloaded to `~/.local/bin` for Linux or `~/Library/Python/2.7/bin` for Mac OS,
-[modify your `$PATH` environment variable](http://www.linfo.org/path_env_var.html)
-so that it contains this path and then, from the root of the project, run `make docs`
-
-If `make docs` is successful, you should be able to see your modifications:
-
-```bash
-$YOUR_FAVORITE_BROWSER {{ docs_path }}/_build/html/index.html
-```
-
-If your PR contains a new feature, you must add documentation for it.
-Of course, you can also create PRs consisting only in documentation changes.
-
-Documentation contributions should comply with [the Symfony documentation standards][sf_docs_standards].
-
-#### The tests
-
-If your PR contains a fix, tests should be added to prove the bug.
-
-If your PR contains an addition, a new feature, this one has to be fully covered by tests.
-
-Some rules have to be respected about the test:
-
-* Annotations about coverage are prohibited. This concerns:
-  * `@covers`
-  * `@coversDefaultClass`
-  * `@coversNothing`
-  * `@codeCoverageIgnore`
-  * `@codeCoverageIgnoreStart`
-  * `@codeCoverageIgnoreEnd`
-* All test methods should be prefixed by `test`. Example: `public function testItReturnsNull()`.
-* All test method names must be in camel case format.
-* As opposed, the `@test` annotation is prohibited.
-* Most of the time, the test class should have the same name as the targeted class, suffixed by `Test`.
-* The `@expectedException*` annotations are prohibited. Use `PHPUnit_Framework_TestCase::setExpectedException()`.
-
-##### Using test doubles
-
-Since version 4.5, PHPUnit requires and [integrates](https://phpunit.de/manual/current/en/test-doubles.html#test-doubles.prophecy)
-the [phpspec/prophecy](https://github.com/phpspec/prophecy).
-Historically, Sonata has been using [the built-in test doubles implementation](https://phpunit.de/manual/current/en/test-doubles.html),
-but [has decided to move to Prophecy](https://github.com/sonata-project/dev-kit/issues/89),
-which is more concise than its built-in counterpart is most cases.
-This means the current Sonata codebase currently uses both implementations.
-If you want to contribute a test that uses test doubles, please follow these rules :
-
-1. All new test classes MUST use Prophecy.
-2. If you are changing an existing test method, you MUST use the same implementation it already uses,
-and focus on the goal of your PR and only on that.
-3. If you are changing an existing test class, you MUST use the same implementation it already uses,
-to be more consistent.
-4. You MAY submit a PR that migrates a test class from the built-in test double implementation to Prophecy,
-but it must migrate it entirely. The PR should only be about the migration.
-
-### Writing a Pull Request
-
-#### The subject
-
-Ideally, a Pull Request should concern one and **only one** subject, so that it
-remains clear, and independent changes can be merged quickly.
-
-If you want to fix a typo and improve the performance of a process, you should
-try as much as possible to do it in a **separate** PR, so that we can quickly
-merge one while discussing the other.
-
-The goal is to have a clear commit history and make a possible revert easier.
-
-If you found an issue/typo while writing your change that is not related to
-your work, please do another PR for that. In some rare cases, you might be
-forced to do it on the same PR. In this kind of situation, please add a comment
-on your PR explaining why you feel it is the case.
-
-#### The Change log
-
-For each PR, a change log must be provided.
-
-There are few cases where no change log is necessary:
-
-* When you fix a bug on an unreleased feature.
-* When your PR concerns only the documentation (fix or improvement).
-
-**Do not** edit the `CHANGELOG.md` directly though, because having every
-contributor write PR with changes in the same file, at roughly the same line is
-a recipe for conflicts. Instead, fill in the dedicated section that should
-appear in a textaread when submitting your PR.
-
-Your note can be put on one of these sections:
-
-* `Added` for new features.
-* `Changed` for changes in existing functionality.
-* `Deprecated` for deprecation of features that will be removed in next major release.
-* `Removed` for deprecated features removed in this release.
-* `Fixed` for any bug fixes.
-* `Security` to invite users to upgrade in case of vulnerabilities.
-
-More information about the followed changelog format: [keepachangelog.com](http://keepachangelog.com/)
-
-#### The base branch
-
-Before writing a PR, you have to check on which branch your changes should be based.
-
-Each project follows [semver](http://semver.org/) convention for release management.
-
-Here is a short table resuming on which you have to start:
-

-
-Notes:
-  * Branch `{{ legacy_branch }}` is the branch of the **latest stable** patch releases and
-  has to be used for Backward Compatible bug fixes only.
-  * Branch `{{ stable_branch }}` is the branch of the **latest stable** minor release and
-  has to be used for Backward compatible enhancement PRs.
-  **No bug fix will be accepted here**, except if the bug fix concerns `{{ stable_branch }}` and **only this one**.
-  Bug fixes merged on `{{ legacy_branch }}` will be ported on other branches by fallback merging.
-  * If you PR is not **Backward Compatible** but can be, it **must** be:
-    * Changing a function/method signature? Prefer create a new one and deprecate the old one.
-    * Code deletion? Don't. Please deprecate it instead.
-    * If your BC PR is accepted, you can do a new one on the `{{ unstable_branch }}` branch which removes the deprecated code.
-    * SYMFONY DOC REF (same logic)?
-
-If you have a non-BC PR to propose, please try to create a related BC PR first.
-This BC PR should mark every piece of code that needs to be removed / uncommented / reworked
-in the corresponding non-BC PR with the following marker comment : `NEXT_MAJOR`.
-When the BC PR is merged in the stable branch, wait for the stable branch to be
-merged in the unstable branch, and then work on your non-BC PR.
-
-For instance, assuming you want to introduce a new method to an existing interface, you should do something like this:
-
-```php
-<?php
-
-namespace Foo;
-
-interface BarInterface
-{
-  /**
-   * NEXT_MAJOR: Uncomment this method
-   *
-   * This method does useful stuff.
-   */
-  // public function usefulMethod();
-
-  // …
-}
-```
-
-In some cases, you will have the possibility to warn the user that things will change,
-and recommend a new way of doing things. You can do so by triggering the dedicated kind of error, like this:
-
-```php
-<?php
-if (/* some condition showing the user is using the legacy way */) {
-    @trigger_error(
-        'The '.__METHOD__.' method is deprecated since 42.x, to be removed in 43.0. '.
-        'Use FooClass::barMethod() instead.',
-        E_USER_DEPRECATED
-    );
-} else {
-    // new way of doing things
-}
-```
-
-Additionally, and when applicable, you must use the `@deprecated` tag on classes or methods you wish to deprecate,
-along with a message directed at the end user (as opposed to other contributors).
-
-
-```php
-/**
- * NEXT_MAJOR: remove this method
- *
- * @deprecated since 3.x, to be removed in 4.0. Use Foo::bar instead.
- */
-public function baz()
-{
-}
-```
-
-In that case, unit tests might show your deprecation notice. You must mark such tests with the `@group legacy` annotation,
-and if need be, isolate them in a new test method that can simply be removed in the non-BC PR.
-
-Be aware that pull requests with BC breaks could be rejected
-or postponed to next major release if BC is not possible.
-
-If you are not sure what should be done, don't hesitate to open an issue about your PR project.
-
-#### The commit message
-
-Sonata is a big project with many contributors, and a big part of the job is
-being able to understand the code at all times, be it when submitting a PR or
-looking at the history. Good commit messages are crucial to achieve this goal.
-
-There are already a few articles (or even single purpose websites) about this,
-we cannot recommend enough the following:
-
-* http://rakeroutes.com/blog/deliberate-git
-* http://stopwritingramblingcommitmessages.com
-* http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html
-
-To sum them up, the commit message has to be crystal clear and of course,
-related to the PR content.
-
-The first line of the commit message must be short, keep it under 50
-characters. It must say concisely but *precisely* what you did. The other
-lines, if needed, should contain a complete description of *why* you did this.
-
-Bad commit message subject:
-
-```
-Update README.md
-```
-
-Good commit message subject :
-
-```
-Document how to install the project
-```
-
-Also, when you specify what you did avoid commit message subjects with "Fix bug
-in such and such feature". Saying you are fixing something implies the previous
-implementation was wrong and yours is right, which might not even be true.
-Instead, state unquestionable technical facts about your changes, not opinions.
-Then, in the commit description, explain why you did that and how it fixes
-something.
-```
-call foo::bar() instead of bar::baz()
-
-This fixes a bug that arises when doing this or that, because baz() needs a
-flux capacitor object that might not be defined.
-Fixes #42
-```
-
-The description is optional but strongly recommended. It could be asked by the
-team if needed. PR will often lead to complicated, hard-to-read conversations
-with many links to other web pages.
-
-The commit description should be able to live without what is said in the PR,
-and should ideally sum it up in a crystal clear way, so that people do not have
-to open a web browser to understand what you did.
-Links to PRs/Issues and external references are of course welcome, but should
-not be considered enough. When you reference an issue, make sure to use one of
-the keywords described in [the dedicated github
-article](https://help.github.com/articles/closing-issues-via-commit-messages/).
-
-Good commit message with description :
-
-```
-Change web UI background color to pink
-
-This is a consensus made on #4242 in addition to #1337.
-
-We agreed that blank color is boring and so deja vu. Pink is the new way to do.
-```
-(Obviously, this commit is fake. :wink:)
-
-## Code Reviews
-
-Grooming a PR until it is ready to get merged is a contribution by itself.
-Indeed, why contribute a PR if there are hundreds of PRs already waiting to get reviewed and hopefully, merged?
-By taking up this task, you will try to speed up this process by making sure the merge can be made with peace of mind.
-
-### Commenting on a PR
-
-Before doing anything refrain to dive head-first in the details of the PR and try to see the big picture,
-to understand the subject of the PR. If the PR fixes an issue, read the issue first.
-This is to avoid the pain of making a reviewer rework their whole PR and then not merging it.
-
-Things to hunt for :
-
-- missing docs . This is what you should look for first. If you think the PR lacks docs,
-ask for them, because you will be better at reviewing it if you understand it better,
-and docs help a lot with that.
-- missing tests : Encourage people to do TDD by making clear a PR will not get merged
-if it lacks tests. Not everything is easy to test though, keep that in mind.
-- BC breaks : If there is a BC-break, ask for a deprecation system to be created instead,
-and make sure the `master` branch is used.
-- Unclear pieces of code : does the code use clear, appropriate variable or class names,
-or does it use names like `data`, `result`, `WhateverManager`, `SomethingService`?
-Are exception names still meaningful if you remove the `Exception` suffix? Do all
-exceptions have a custom message?
-Is the contributor trying to be clever or to be clear?
-- Violations of the [SOLID][solid] principles :
-    - S : If a class is 3000 lines long, maybe it does too many things?
-    - O : Is there a big switch statement that might grow in the future?
-    - L : Does the program behave reasonably when replacing a class with a child class?
-    - I : Are interfaces small and easy to implement? If not, can they be split into smaller interfaces?
-    - D : Is the name of a class hardcoded in another class, with the `new` keyword or a static call?
-- Spelling / grammar mistakes, including in commit messages or UPGRADE / CHANGELOG notes.
-- Dependency modifications : is anything new introduced, if yes is it worth it?
-
-[solid]: https://en.wikipedia.org/wiki/SOLID_(object-oriented_design)
-
-Leave no stone unturned. When in doubt, ask for a clarification. If the
-clarification seems useful, and does not appear in a code comment or in a commit
-message, say so and / or make use a squash-merge to customize the commit message.
-Ideally, the project history should be understandable without an internet connection,
-and the PR should be understandable without having a look at the changes.
-
-Also, make sure your feedback is actionable, it is important to keep the ball rolling,
-so if you raise a question, try to also provide solutions.
-
-### Labelling the PR
-
-Applying labels requires write access to PRs, but you can still advise if you do not have them.
-There are several labels that will help determine what the next version number will be.
-Apply the first label that matches one of this conditions, in that order:
-
-- `major`: there is a BC-break. The PR should target the `master` branch.
-- `minor`: there is a backwards-compatible change in the API. The PR should target the stable branch.
-- `patch`: this fixes an issue (not necessarily reported). The PR should target the stable branch.
-- `docs`: this PR is solely about the docs. `pedantic` is implied.
-- `pedantic`: this change does not warrant a release.
-
-Also if you see that the PR lacks documentation, tests, a changelog note,
-or an upgrade note, use the appropriate label.
-
-### Reviewing PRs with several commits
-
-If there are several commits in a PR, make sure you review it commit by commit,
-so that you can check the commit messages, and make sure the commit are independent
-and atomic.
-
-### Merging
-
-Do not merge something you wrote yourself. Do not merge a PR you reviewed alone,
-instead, merge PRs that have already be reviewed and approved by another reviewer.
-If the commit history is unclear or irrelevant, prefer the "Squash and merge" feature, otherwise, always
-use the "Rebase and merge" feature.
-And finally, use your common sense : if you see a PR about a typo,
-or if there is a situation (faulty commit, revert needed) maybe you can merge it directly.
-
-### Be nice to the contributor
-
-Thank them for contributing. Encourage them if you feel this is going to be long.
-In short, try to make them want to contribute again. If they are stuck, try to provide them with
-code yourself, or ping someone who can help.
