Git nedir?
Git ücretsiz ve açık bir kaynaktır dağıtılmış sürüm kontrol sistemi. “Dağıtılmış”, deponun merkezi bir kopyası olmadığı anlamına gelir. Git ile, depoyu klonladıktan sonra, kaynak kodu 'nun, tüm dalları ve emrinize.

Gerrit nedir?
Gerrit Git ile entegre olan ücretsiz, web tabanlı bir ortak kod inceleme aracıdır.

Basically: You submit your proposed software change (often called "patch", in Gerrit called "changeset") as a new branch. If the first version ("patchset 1") is not yet perfect, you can make more changes ("amend") in that branch ("patchset 2", etc). Once a patchset receives a "+2" review, it will get accepted and merged into the main branch of the code repository (usually called "master"). Merging means that your change is included by default when anyone checks out or downloads that code repository.

 * Use the graphical software package management tool of your Linux distribution to install the  package.
 * If git has not been packaged by your distribution, then please ask in a support forum of your distribution.

Font Awesome 5 brands windows.svg Windows

 * Install Git for Windows from https://gitforwindows.org/. This gives you Git, plus a shell called "Git Bash" that allows most of the command lines in these instructions to work on Windows.
 * If you want additional integration with the Windows shell, see Gerrit/TortoiseGit tutorial.

 * Install the Homebrew package manager and then run the command – This is recommended, as it allows simple updating and easy installing of other packages.
 * As an alternative, you can install the stand-alone Git for Mac.

Now that you have Git installed, it’s time to configure your personal information. You should have to do this only once. You can also change your personal information at any time by running these commands again.

Git tracks who makes each commit by checking the user’s name and email. In addition, this info is used to associate your commits with your Gerrit account.

Enter the two commands below to set your username and email address. Replace with your own Gerrit username and replace  with your own email address:

To see your current configuration variables which control how Git behaves, use.

Gerrit'te SSH Anahtarlarını Ayarla
We use an SSH key to establish a secure connection between your computer and Gerrit. To make sure whether you need to generate a brand new key, let's check if an SSH key already exists on your system. Run this command in a terminal:

The command will list the files that are in the (hidden)  directory. If the directory already exists on your system and if the output lists a file called, then you can go directly to.

Yeni bir SSH anahtarı oluşturun
To generate a new SSH key, enter the command below and replace with your own email address. We want the default settings so when asked to enter a file in which to save the key, just press enter.

Enter a strong and unique passphrase and press the [Enter] key.


 * Why do passphrases matter?
 * Passwords aren’t very secure. If you use one that’s easy to remember, it’s easier to guess or brute-force. If you use one that’s random it’s hard to remember, so you might write the password down. Both are very bad. This is why you’re using ssh keys. But using an ssh key without a passphrase is basically the same as writing down that random password in a file on your computer. Anyone who gains access to your drive has gained access to every system you use that key with. That's why you also add a passphrase. To not enter a long passphrase every time you use the key, there’s a tool called . It can save your passphrase securely. If you use macOS or Linux, then your keys can be saved in the system’s keychain to make your life even easier.

The  command will create 2 files in   directory:
 * : your private SSH key (for identification)
 * : your public SSH key

SSH Genel anahtarınızı kopyalayın
Get the content of your public key file (e.g. ) to copy it to your clipboard:

One option is to open your public key file with your favorite text editor (Notepad, TextEdit, gedit, etc). In the file chooser dialog of your text editor, you may need to turn on “View hidden files” to find the file, because the  directory is hidden. Sometimes the “View hidden files” option is available by right-clicking in the file chooser dialog.

Other options are:
 * On Linux, run and manually copy the output to the clipboard.
 * On Windows, you can open Git GUI, go to Help 🡒 Show Key, and then press "Copy To Clipboard" to copy your public key to your clipboard.
 * On macOS, you can run to copy the contents of the your public key file to your clipboard.

It’s important you copy your SSH Public key exactly as it is written, without adding any newlines or whitespace. Copy the full text, including the "ssh-rsa" prefix, the key itself, and the email address suffix.

Gerrit hesabınıza SSH Genel anahtarı ekleyin

 * Log into the web interface for Gerrit. The username and password for your Gerrit are the same as for your Wikimedia Developer account.
 * Click on your username in the top right corner, then choose "Settings".
 * Click "SSH Public Keys" in the menu on the left.
 * Paste your SSH Public Key into the corresponding field and click "Add".

 * Be sure to use the accent, not the single quote  . (You could copy and paste from this page if you cannot easily enter this special character.)


 * Add your private key to the agent. If you followed the steps above and your key has the default name, then the command is:


 * Connect to the Gerrit server via  to check if everything works as expected. Replace  by your username as shown in your Gerrit settings:


 * Be paranoid and compare that the "RSA key fingerprint" is the same as the SSH fingerprint for gerrit.wikimedia.org:29418. If it is the same, answer "Yes" to "Are you sure you want to continue connecting?". Then enter the passphrase for your key.
 * You should get a message "Welcome to Gerrit Code Review". The last line should show "Connection to gerrit.wikimedia.org closed."
 * If you run into problems, use (replace  by your username). The   will provide verbose output to help find problems. Then read Gerrit/Troubleshooting.

An example Gerrit SSH connection success message looks like this:

Git'i kullanarak kod indirin
Let's practice by downloading (also called "cloning") the repository called "sandbox". Run the following on the Git Bash command line:

(Replace by your Gerrit username. And make sure the URL begins with   and not  ).

This will copy the entire history and the code base of the "sandbox" extension repository onto your machine. You will have a working directory of the extension's main branch (usually also called "git master"). Enter the new directory (via the command ). Now you can look at the code and start editing it.

Cloning the Sandbox repository will not give you a development environment setup or a running MediaWiki installation. (Running will require MediaWiki Core and placing the code you checked out in a location expected by your web server.) See Download from Git how to download MediaWiki Core, extensions, skins, or any other project repository hosted at gerrit.wikimedia.org from Git.

Gerrit ile çalışmaya hazırlanın
Gerrit requires that your commit message must have a "change ID". They look like  starting with an I (capital i). Each time you amend a commit to improve an existing patch in Gerrit, this change ID stays the same, so Gerrit understands it as a new "patch set" to address the same code change.

There's a git add-on called git-review that adds a Change-ID line to your commits. Using git-review is recommended. It makes it easier to configure your Git clone, to submit a change or to fetch an existing one.

Git-review yükleme
For more details, please see Gerrit/git-review.

 * Use the graphical software package management tool of your Linux distribution to install the  package.
 * If git-review has not been packaged by your distribution, check Gerrit/git-review for other options such as installing git-review by using the pip Python package installer.
 * If you use FreeBSD, install git-review through ports.

 * For OS X 10.11 El Capitan and later, follow Gerrit/git-review.
 * On versions prior to 10.11, use the pip Python package installer by following Gerrit/git-review.

Git-review yapılandırma
Git's default remote host name is "origin". This name is also used by Wikimedia projects. We need to tell git-review to use that host. Replace with your Gerrit username:

Git-review ayarlama
After downloading ("cloning") a repository, you need to set it up for git-review. This will automatically happen the first time you try to submit a commit, but it's generally better to do it right after cloning. Make sure that you are in the directory of the project that you cloned (otherwise you will get an error "fatal: Not a git repository"). Then run this command:

Towards the end of the output, you should see something like this:

This may ask you for your git username, if it's different from the shell username you're using.

If you could not install, then you could use the Gerrit patch uploader to submit a patch.

Bir yama gönderin
Make sure that you cloned the code repository that you are interested in (see ).

Make sure that you are in the directory of the code repository (the command tells you where exactly you are).

Güncelleme yöneticisi
Make sure that your master branch (the branch created when you initially cloned the repository) is up to date:

However, note that a few repositories use different terms (for example, the  repository has a   instead of a   branch).

Bir dal oluştur
First, create a local branch for your new change. Replace below by a short but reasonably descriptive name (e.g.   if a corresponding Phabricator task exists for your changes, , or  ). Other people will also use this name to identify your branch.

This will create a new branch (called ) from the latest 'master' and check it out for you. In the example above, we called that new branch.

Değişikliklerinizi yapın
Make changes to your local code. Use your preferred text editor and modify a file. In the example below, we edit the file  and add a word.

Then close your text editor and check the changes you have made since the last commit, within the file(s) and within the directory:

displays your changes in unified diff format: Removed lines have a minus prefix and added lines have a plus  prefix. These changes are not yet "staged" (via ) for the next commit.

Stage your changes for a commit
Run to decide which of your changes should become part of your commit. It will display a list of all file(s) that you have changed within the directory. At this point, the output will display "no changes added to commit" as the last line.

Use  to make your changed file(s) become part of your next commit. In the example above we modified the file, so the command would be:

Any files you've changed that you have not passed to  will be ignored when running   in the next step.

At any time you can always review the changes already staged by running. After you ran,   will not show the line "no changes added to commit" anymore.

You can also use to see which changes are staged and will go into the next commit. The output will look the same as for the  command above.

Commit your staged changes
Once you are happy with the list of changes added via, you can turn these changes into a commit in your local repository by using

You will then be asked in your text editor to add a descriptive summary for your commit. You must follow the Commit message guidelines. This is what other people will see when looking at the history of changes in the code repository.

Save the commit message and close your text editor. A summary (the commit ID, your subject line, the files and lines changed) will be displayed.

You can repeat this step over and over until you have a set of changes that you want to have pushed to the master branch. When you, you are committing to your local copy. This means you can commit as often as you like without potentially screwing things up for another developer on the project.

Prepare to push your commit to Gerrit
Synchronize your changeset with any changes that may have occurred in the master branch while you've been working ("rebasing"). From within your branch, run:

will fetch new commits from the remote and then rebase your local commits on top of them. It will temporarily set aside the changes you've made in your branch, apply all of the changes that have happened in master to your working branch, then merge (recommit) all of the changes you've made back into the branch. Doing this will help avoid future merge conflicts. Plus, it gives you an opportunity to test your changes against the latest code in master.

Now you are ready to push your code to Gerrit for review. If you made several related commits, consider merging them into one single commit for review.

Push your commit to Gerrit
If you followed above and installed   and ran , then the command to push changes to Gerrit is:

The  option tells git-review not to perform a rebase before submitting the change to Gerrit.

Upon success, you'll get a confirmation and a link to the changeset in Gerrit. In the example above, that link is: https://gerrit.wikimedia.org/r/#/c/sandbox/+/563720

Congratulations! Your patch is in Gerrit and hopefully will get reviewed soon!

View the Change / Next Steps
If you open the link to your Gerrit changeset in a web browser, you can see your changed files in their context when you click on the  link in the "Commit" line.

In 2020, Gerrit's new web interface called "PolyGerrit" will become the default. You can use PolyGerrit via https://gerrit.wikimedia.org/r/?polygerrit=1 and the old interface via https://gerrit.wikimedia.org/r/?polygerrit=0

If your commit addresses a ticket in Phabricator, a comment will be automatically added in the Phabricator task if you followed the Commit message guidelines. If you did not, you could manually add a comment on that Phabricator ticket by linking to its changeset in Gerrit.

Gerrit's diff algorithm (jGit) is slightly different from git's default diff algorithm. The differences displayed by Gerrit might not look like the differences displayed by Git on your machine.

Other common situations
Also see Gerrit/Advanced usage if your situation is not covered here.

Squash several commits into one single commit via rebase
If you made several related commits to your local repository prior to wanting to submit for review, you should squash (merge) those commits into one single commit.

The  or   option allows you to change (rewrite) your commit history. For each commit, you can modify and change the commit message, add or remove files, or perform other modifications.

First you need to tell git how far back you want to pull. To get a list of all changes in your branch:

You can also limit the displayed list of recent changes. means pull the last three commits:

After you type this command, your text editor will display your commits in reverse order and a list of available commands:

Since we only want to send one commit to review, we will squash the last two commits into the first. Hence change all but the first "pick" to "squash": pick aa8cf1d Adding method customFilterFunctionGetRiskyCountryCodeScore to GatewayAdapter. squash 38828e2 Adding $wgDonationInterfaceCustomFiltersFunctionsRiskyCountries to donationinterface.php squash be33007 Fix a typo

When you finished picking and squashing and saved the file, another file will open in your text editor to allow you get to edit and merge your commit messages. Be careful to only keep one of the Change-Id lines and have it be at bottom of the message after one empty line.

Your messages from your previous commits will automatically be placed in this message:

Remember to put your (updated) summary message in the commit. In this case the new summary message will be: (mingle-fr-2012-69) Adding a custom filter for risky countries.

''In regards to which Change-Id you want to use, squashing a commit into an existing commit (one that's already in Gerrit), you need to pick the Change-Id that belongs to the one you meant to submit a new patchset for (the surviving commit). If your commits are new and are not in Gerrit, it does not matter which Change-Id you choose.''

If all goes well, you should see a successful rebase message:

Afterwards, submit your patch for review:

You should see a message like this showing your git review went to Gerrit (in this example, to https://gerrit.wikimedia.org/r/7187 ):

Amending a change (your own or someone else's)
Sometimes, you might need to amend a submitted change. You can amend a change as long as the change hasn't been merged yet.

You can amend your own changes. To amend changes submitted by someone else, you need to be a member of Gerrit's Trusted-Contributors group. To become a member of Trusted-Contributors, find someone who is a member and ask them to add you. The group is viral in that members can add new members, use your powers responsibly.

Rebase to bring your local branch up to date with the remote. It's best to make rebase updates a separate patch, so that your code reviewers have an easy time seeing what changes you've made. Assuming you are using Gerrit, you can do this by clicking the "Rebase Change" button when viewing your patch in Gerrit's web interface.

Hard reset and checkout the change with this command: (BEWARE:  performs a hard reset that destroys all local changes. Stash or commit changes first which you wish to preserve!)

For example:

Note, if you already have the change in a branch on your local repository, you can just check it out instead:

For example:

Next, make some changes with your favorite text editor.

the files as needed, then commit the change (ensuring you are amending the commit):

DO NOT use the  flag to specify a commit summary: that will override the previous summary and regenerate the Change-Id. Instead, use your text editor to change the commit summary (in the file  if needed, and keep the Change-Id line intact.

Push the change:

The  is important here. It tells git-review to not rebase your change against master, which clutters diffs between patch set 1 and 2.

Push to a branch different than master
Above, the commit was pushed to the master branch. The branch name only appeared as the topic of the commit in the Gerrit UI. If you really want to push to a different branch than master, you have to push via.

Editing via the web-interface
If you're logged in to Gerrit, you can also create code changes directly within the web interface. This can be useful for making small patches, or for non-developers to contribute small fixes.

Done!
 * 1) Go to https://gerrit.wikimedia.org/r/?polygerrit=0#/admin/projects/foo replacing   with the code repository (e.g. https://gerrit.wikimedia.org/r/?polygerrit=0#/admin/projects/mediawiki/extensions/Echo )
 * 2) Click "Create Change"
 * 3) Set branch to "master" (if you don't want to use master branch you can use the other branches available for that project)
 * 4) Set the topic to something of your choosing (e.g. "copy-edit" - must be all-one-string) (optional)
 * 5) Write a description ("commit summary") in the big text field by following Gerrit/Commit message guidelines. (Example)
 * 6) Click "Create"
 * 7) Under "Files", click the "Edit" button
 * 8) Under "Files", click "Add"
 * 9) Type the folder/file path for the file you wish to edit (e.g. i18n/en.json) and click "Open"
 * 10) Find the line(s) you want to change, and change them.
 * 11) Click "Save"
 * 12) Click "Close"
 * 13) Click "Publish edit"
 * 14) Click the button "Start Review"

For steps 1-6 there is also an alternative way:
 * 1) Go to https://gerrit.wikimedia.org/r/#/projects/foo,dashboards/default (e.g. https://gerrit.wikimedia.org/r/#/projects/mediawiki/extensions/Echo,dashboards/default )
 * 2) Click the topmost patch under "Merged Changes" of the chosen branch (e.g. master)
 * 3) Click "Follow-Up"
 * 4) Write a description ("commit summary") in the big text field similarly as in the step 5 above
 * 5) Click "Follow-Up"
 * 6) Change the topic to something of your choosing (e.g. "copy-edit" - must be all-one-string) (optional)

If you need to change the commit summary, you can use these steps:
 * 1) Under "File Path", click "Commit Message"
 * 2) On top of the right panel, click the "Edit" button
 * 3) Make changes to the commit summary.
 * 4) Click "Save"
 * 5) Click "Close"
 * 6) Click "Publish edit"

How code is reviewed in Gerrit
Code review is an essential part of our contribution workflow. The principle is basic: any patch must be reviewed by others before being merged.

This means that your code will need reviewers. Check our advice for getting reviews.

Review before merge
It's important to us to have a review-before-merge workflow for MediaWiki core and also for any extension we deploy. We will also offer that option to any extension author who wants it for their extension. The one exception is localisation and internationalisation commits, which will be able to be pushed without review.

Who can review? Gerrit project owners
After creating a Developer account, anyone can comment on commits and express criticism and approvals. Anyone can give a nonbinding "+1" to any commit. However, for any given repository ("Gerrit project"), only a small group of people will have the ability to approve code within Gerrit and merge it into the repository. This superapproval is a "+2" even though that's a misleading name, because two +1 approvals DO NOT add up to a +2. These people are "Gerrit project owners".

How to comment on, review, and merge code in Gerrit








Anyone can comment on code in Gerrit.

Viewing and commenting on code

 * Make sure that you have a developer account.
 * Log in to Gerrit. If you know the changeset you want to look at (URL will look like https://gerrit.wikimedia.org/r/#/c/23939/ ), go to that. Otherwise, use the search box. You can search by author ("Owner"), Gerrit project, branch, changesets you've starred, etc. The Gerrit search documentation covers all of the different search operators you can use.
 * The changeset has a few fields, links and buttons:
 * Assignee. An optional field to make a single person responsible for handling reviewing the changeset. This should only be set if the assignee has agreed.
 * Reviewers. 'jenkins-bot' is the autoreviewer that auto-verifies anything that passes the Jenkins tests. It will report a red or green mark depending on whether the build passes.
 * The Add" button on the right of Reviewers:'''. Manually pings someone to request their review. It'll show up in their Gerrit dashboard.
 * Files: Open All. Opens the diff (each file in a separate browser tab). You can double-click on a line and then press C to comment on that line, then save a draft comment! Then, click the green "Up to change" arrow to go back to the changeset, and click "Reply…" to publish your comment.
 * Reply… ("Add comment"). Publish your thoughts on the commit, including an overall comment and/or inline comments you added (see above).
 * If, upon code review, you approve, use "+1" under "Reply…"; otherwise, use "-1" to disapprove. These numbers are nonbinding, won't cause merges or rejections, and have no formal effect on the code review.
 * Abandon (you'll see this if you wrote this diff). This action removes the diff from the list to review, but leaves it in Gerrit for archival purposes.

Comparing patch sets
Every time you amend your commit and submit it for review, a new patch set is created. You can compare the different patch sets like this:
 * Under Files, select either Open All or choose a specific file listed to open that file.
 * On the left side under Patch Set, Base is preselected. On the right of the screen under Patch Set, the latest patch set is preselected. Adjust the selected patch sets to your needs.

Formally reviewing and merging or rejecting code
If you are one of the Gerrit project owners, you'll also see:
 * Abandon button
 * under Reply, additional Code-Review options to +2 (approve) or -2 (veto) a diff, and a Post button (publish your comment and merge diff into the branch, in 1 step)
 * Submit button (merge -- only useful if you or someone else has already given a +2 approval to the diff, but not merged it)

And once you've merged something into the example Gerrit project you'll see it in https://gerrit.wikimedia.org/r/plugins/gitiles/test/mediawiki/extensions/examples/.

If you merged a commit that references a task in Phabricator and that commit is supposed to fix that task completely, please go to that task and change its status to "Resolved" (via the Add Action… 🡒 Change Status dropdown). Also reference the merge ID if gerritbot has not already posted it in that task.
