Gerrit/Commit message guidelines/id

The commit message of your change plays an important role. It is first thing other people will see about your change.

Subyek
The first line of the commit message is known as the subject. The subject should be less than 80 characters long (aim for 50-70).

Keep in mind that this will be in the repository forever. The imperative mood sounds like you are giving instructions to someone, it could start with words like "Change", "Add", "Fix", "Remove", "Update", "Refactor", or "Document". A component is the general area that your commit will change.
 * Summarize your change in the subject line.
 * Use the imperative mood in your subject line.
 * Good examples are "Add Badge::query for querying the API" or "Allow zeroes in SimpleBadge::add".
 * Bad examples would be "Added Badge::query method" or "Fixed Badge::query method", or "Badge can query the API" and "Zeroes work when adding badges".
 * Your commit title should be short, clear what you are doing, and specific to the change you are making. It should not be possible to use the same title for commits that do different things. People will use your commit title as they see it pass by in change feeds and blame logs to guess if they are interested in, or worried by, the change.
 * Good examples: "SimpleBadge: Add hover labels to form, for screenreader accessibility", "DatabaseFiddler: Avoid infinite loop when given null input", or "Diffs: Adjust display colours to align with new April 2020 design standard".
 * Bad examples: "Implement accessibility fixes", "Don't crash", or "Make prettier with a better design".
 * Do not end the subject line with a period/full stop/dot.
 * Optionally, prefix the subject with the relevant component.

Body
When writing the body text, think about the following questions:

What is wrong with the current code? Are there other ways? If so, describe why they were not as good.
 * Why should this change be made?
 * Why should it be changed in this way?
 * Did you consider other approaches?
 * How can a reviewer test or verify that your code is working correctly?

Do:

However, do not break URLs to make them 'fit', as this will make them un-clickable; keep them, even if they are longer. If they are not yet merged, refer to them by using their Gerrit Change-Id.
 * … separate the body from the subject with one empty line.
 * … manually wrap the message so that title and body lines are a maximum of 100 characters long.
 * … refer to other commits by using a (short) Git commit hash if they are merged.

Jangan:


 * … refer to other commits with a Gerrit URL.
 * Instead, use the Git commit hash. This allows easy navigation of the Git repository when offline. It also allows users of all repository viewers (Gerrit, Gitiles, Phabricator, GitHub, and local Git interfaces) to automatically navigate to other commits within the same interface. A URL can only be resolved when online and using Gerrit, which breaks the ability for people to navigate quickly.
 * … use a URL as the only explanation for a change.
 * If the change is justified by discussions elsewhere or external documentation, then briefly summarise the relevant points in the commit message.

Footer and meta-data
The most important information of the footer is the  (mandatory) and.

Format "Bug" and "Change-Id" meta-data exactly like in the examples below, and place them together at the end of the body, after one empty line.

Find more information on individual meta-data fields below.

Subyek
Most programs we use that display Git commit, render the subject line as plain text. This means URLs do not work, and selecting/copying of text often is not possible. Therefore, do not mention Phabricator tasks, Git commits, or urls inside the subject line. Instead, mention those in the body text, or footer meta-data. That way, they can be universally selected, copied, or clicked.

,,  ,  , etc.
 * Gerrit uses the subject in: email notifications, IRC notifications, search results.
 * GitHub uses the subject in: commit history, commit subject.
 * The Git CLI uses the subject in:
 * dan banyak lagi!
 * dan banyak lagi!

Komponen
You may start the subject line with a component, which will indicate what area of the project is changed by your commit.

It should be one of the following:


 * A directory of PHP classes under  or , such as "installer", "jobqueue", "objectcache", "resourceloader", "rdbms", etc.
 * A PHP class name, such as "Title", "User", "OutputPage", etc.; typically for classes without subdirectory in.
 * ResourceLoader module name (like "mediawiki.Title", "mediawiki.util", etc.).
 * Generic keyword affecting multiple areas relating to the type of change, such as:
 * "build" - for changes to files relating to the development workflow, such as updates to,  , etc.
 * "tests", "qunit", "phpunit" - for changes that only affect unit or integration test suites, or the test suite runners.

Phabricator
To reference a bug or task, in the commit message mention it inline using the Txxx notation (e.g. "That was caused by T169.")

To express that a commit resolves (even partially) or is specially relevant to a bug, add  in the footer at the end of the commit message. (If you're amending a commit message, insert it immediately above the  line, without an empty line between them. Remember to follow the overall structure rules and separate the body from the subject with one empty line.)

Bug: T169

A bot will automatically leave a comment on the Phabricator task about any significant events (being merged, abandoned, etc.). If a patch resolves two or more bugs, put each  reference on its own line at the bottom.

Cross-references
Whenever you refer to another commit, use the SHA-1 git hash of the merged commit. If the commit in still pending review, use the Gerrit Change-Id hash instead of the git hash because the hash relates to an individual patch set (which changes when rebased, thus creating a dead-end).

Change-Id
's  tool will automatically append the " " keyword to new commits.

Ketergantungan
If you have cross-repo dependencies (your commit depends on another commit in a different repository), declare them by adding  to the last paragraph. ("Ixxx"... is the  of the other commit.) This will instruct Zuul to test the commit together with that one.

Crediting others
Add this line before the  to credit other developers working on the change. You can add more than one separated by a line break.
