Как сделать так, чтобы ваши изменения кода рассматривались быстрее и с большей вероятностью были приняты?

Предпосылки

 * You have changed some code to fix a bug or add new functionality.
 * You have followed the Coding conventions.
 * You have followed the Pre-commit checklist.
 * You have followed the.
 * You have a to use with Gerrit and successfully set up Git/Gerrit on your machine.

Вы планируете создать патч для загрузки в Gerrit, чтобы ваш код был рассмотрен и смержен (включен в кодовую базу).



Ваш патч


Заранее проверьте на соответствие сфере применения
If your proposed code changes do not fix a bug but introduces a new feature instead, speak first to the maintainers to make sure that your idea is in the project scope and that your proposed technical approach is the optimal solution. This will save you time and potential disappointment.



Протестируйте свои изменения
Test your changes in your development environment to make sure there are no compilation errors or test failures. Если вы по какой-то причине не протестировали свой патч, прямо укажите это в комментарии в Gerrit. Consider going through the Pre-commit checklist.

Избегайте предоставления неполных исправлений или введения новых ошибок. Если вы знаете, что ваш патч нуждается в доработке, прямо укажите это в Gerrit, оценив (reviewing) его как «-2» или добавив к сообщению в коммите префикс «[WIP]» (work in progress — незавершённая работа).



Пишите короткие коммиты
Небольшие, самостоятельные и полные патчи будут приняты с наибольшей вероятностью.

If your commits are going to be touching separate files and there's not a lot of dependency between them, it's probably best to keep them as smaller discrete commits.

Furthermore, make sure to not include unnecessary changes in your patch (e.g. fixing the coding style).

However, if your commits are going to be touching the same files repeatedly, bundle them up into one large commit (using either  or squashing after the fact).

Write a meaningful commit message
Commit message should describe what and why. What was the problem? How does the fix resolve it? How to test that it actually works? See for more.

Also, make sure to proofread and use proper spelling and punctuation in your commit message.

Provide documentation
If a feature in your patch is going to be visible to end users or administrators, make sure to update or create related documentation. See Development policy#Documentation policy for more information.

Don't mix rebases with changes
When rebasing, only rebase. If non-rebase changes are made inside a rebase changeset, you have to read through a lot more code to find it and it's non-obvious. When you're making a real change, leave a Gerrit comment explaining your change, and revise your commit summary to make sure it's still accurate.

Respond to test failures and feedback
Check your Gerrit settings and make sure you're getting email notifications. If your code fails automated tests, or you got some review already, respond to it in a comment or resubmission.

(To see why automated tests fail, click on the link in the "failed" comment in Gerrit, hover over the failed test's red dot, wait for the popup to show, and then click "console output.")

Feedback will usually (but not always) come with a C-2, C-1, C+1, or C+2 flag from Gerrit. You can read more about what these mean (from the reviewer's perspective) at Gerrit/Code review#Complete the review. Some reviewers will offer suggestions for improvement without using an explicit C-1 rating in order to reassure new contributors. You should still take their suggestions seriously.

Sometimes you'll receive reviews which you'll perceive as irrelevant, for instance merely cosmetic. Do not ignore such reviews but amend your patch to satisfy trivial requests: You may disagree, but discussing costs time and is more expensive than conceding a point.

Code review is a matter of building consensus, not winning an election. You are expected to address negative feedback, not "outvote it" by seeking additional positive reviews. Addressing negative feedback does not always require changes to your patch: sometimes all that is required is a better explanation. However, even in those cases it can be useful to incorporate those explanations into the commit message or comments in the code to better inform future maintainers with the same concerns.

In general: Be patient and grow. More experienced patch writers receive faster responses and also more positive ones.

Add reviewers
The choice of reviewers plays an important role on reviewing time. More active reviewers provide faster responses.

Right after you commit, add one or two developers to the changeset as Reviewers. (These are requests – there's no way to assign a review to one specific person in Gerrit.) Experienced developers should help with this: if you notice an unreviewed changeset lingering, then please add reviewers. To find reviewers:


 * Check the main maintainers list, or the maintainers listed in the extension's page, to find who's currently maintaining that part of the code, or is in maintainer training.
 * Click the magnifying glass in the "Project" row of your gerrit patch. Now find other changesets in that repository: the people who write and review those changesets would be good candidates to add as reviewers. Or see who can approve your patch: click "Access" in the top navigation bar, click the link(s) in "Owner" rows, see the list of names.
 * To find out who added a system message and why, see Special:MyLanguage/Gerrit/Navigation for specific advice.
 * Search through other commit summaries and changesets. Navigate the repository tree to your repository or directory and click "View History" to see who is active in the area, for instance changes in the database of MediaWiki core. Or search on Gerrit: Matma Rex and Foxtrott are interested in reviewing frontend changes, so you can search for "message:css" to find changesets that mention CSS in their commit summaries to add them to. You can use this and regexes to find changes that touch the same components you're touching, to find likely reviewers (search docs).

Review more
Many eyes make bugs shallow. Read the Code review guide and help other authors by praising or criticizing their commits. Comments are nonbinding, won't cause merges or rejections, and have no formal effect on the code review. But you'll learn by reviewing, gain reputation, and get people to return the favor by reviewing your proposed code changes in the future. "How to review code in Gerrit" has the step-by-step explanation.

No timely feedback
Manpower in free and open source software projects is limited, and interests of developers may change. Some code repositories are more active and maintained and you will receive quicker reviews. Other areas have unclear maintainership or are even abandoned and you might have to wait for a long time.

You can check the latest activity in a code repository by looking at the "Recent Commits" list of the repository in Diffusion or via  in your local checkout. To take over an abandoned project and become its maintainer, follow these steps.

If you think that your patch has been gone unnoticed for a longer time, feel free to bring up the problem on the IRC channel.

Further reasons for rework or rejection
Even if you have followed all recommendations, your patch might still require some rework (or in rare cases even get rejected).

Apart from what has been mentioned already, there are more potential reasons for rejection (not all of them are equally decisive), such as a suboptimal solution when there is a more simple or efficient way, performance issues, security issues, improvable naming (e.g. of variables), integration conflicts with existing code, duplication of work, unintended (mis)use of the API, or proposed changes to internal APIs being considered too risky.

Be aware that there is a mismatch of judgement: Patch reviewers often consider test failures, an incomplete fix, introducing new bugs, a suboptimal solution, and inconsistent docs way more decisive for rejecting a patch than patch authors.
