17 <h1>Source Code Repository
</h1>
20 Mesa uses
<a href=
"https://git-scm.com">git
</a>
21 as its source code management system.
25 The master git repository is hosted on
26 <a href=
"https://www.freedesktop.org">freedesktop.org
</a>.
30 You may access the repository either as an
31 <a href=
"#anonymous">anonymous user
</a> (read-only) or as a
32 <a href=
"#developer">developer
</a>
38 <a href=

39 >browse the main Mesa git repository
</a> and the
40 <a href=
"https://gitlab.freedesktop.org/mesa/demos"
41 >Mesa demos and tests git repository
</a>.
45 <h2 id=

</h2>
48 To get the Mesa sources anonymously (read-only):
52 <li>Install the git software on your computer if needed.
<br><br>
53 <li>Get an initial, local copy of the repository with:
55 git clone https://gitlab.freedesktop.org/mesa/mesa.git
57 <li>Later, you can update your tree from the master repository with:
61 <li>If you also want the Mesa demos/tests repository:
63 git clone https://gitlab.freedesktop.org/mesa/demos.git
68 <h2 id=
"developer">Developer git Access
</h2>
71 If you wish to become a Mesa developer with git-write privilege, please
72 follow this procedure:
76 <a href=
"https://lists.freedesktop.org/mailman/listinfo/mesa-dev">mesa-dev
</a>
78 <li>Start contributing to the project by
79 <a href=
"submittingpatches.html" target=
"_parent">submitting patches
</a> to
80 the mesa-dev list. Specifically,
82 <li>Use
<code>git send-mail
</code> to post your patches to mesa-dev.
83 <li>Wait for someone to review the code and give you a
<code>Reviewed-by
</code>
85 <li>You'll have to rely on another Mesa developer to push your initial patches
86 after they've been reviewed.
88 <li>After you've demonstrated the ability to write good code and have had
89 a dozen or so patches accepted you can apply for an account.
90 <li>Occasionally, but rarely, someone may be given a git account sooner, but
91 only if they're being supervised by another Mesa developer at the same
92 organization and planning to work in a limited area of the code or on a
94 <li>To apply for an account, follow
95 <a href=
"https://www.freedesktop.org/wiki/AccountRequests">these directions
</a>.
96 It's also appreciated if you briefly describe what you intend to do (work
97 on a particular driver, add a new extension, etc.) in the bugzilla record.
101 Once your account is established, you can update your push url to use SSH:
103 git remote set-url --push
<em>origin
</em> git@gitlab.freedesktop.org:mesa/mesa.git
106 You can also use
<a href=
"https://gitlab.freedesktop.org/profile/personal_access_tokens">personal access tokens
</a>
107 to push over HTTPS instead (useful for people behind strict proxies).
108 In this case, create a token, and put it in the url as shown here:
110 git remote set-url --push
<em>origin
</em> https://
<em>USER
</em>:
<em>TOKEN
</em>@gitlab.freedesktop.org/mesa/mesa.git
114 <h2>Windows Users
</h2>
117 If you're
<a href=
"https://git.wiki.kernel.org/index.php/WindowsInstall">
118 using git on Windows
</a> you'll want to enable automatic CR/LF conversion in
119 your local copy of the repository:
122 git config --global core.autocrlf true
126 This will cause git to convert all text files to CR+LF on checkout,
130 Unix users don't need to set this option.
135 <h2>Development Branches
</h2>
138 At any given time, there may be several active branches in Mesa's
140 Generally,
<tt>master
</tt> contains the latest development (unstable)
141 code while a branch has the latest stable code.
145 The command
<code>git branch
</code> will list all available branches.
149 Questions about branch status/activity should be posted to the
150 mesa-dev mailing list.
153 <h2>Developer Git Tips
</h2>
156 <li>Setting up to edit the master branch
158 If you try to do a pull by just saying
<code> git pull
</code>
159 and git complains that you have not specified a
162 git config branch.master.remote origin
163 git config branch.master.merge master
166 Otherwise, you have to say
<code> git pull origin master
</code>
167 each time you do a pull.
169 <li>Small changes to master
171 If you are an experienced git user working on substantial modifications,
173 working on a separate branch and would rebase your branch prior to
175 But for small changes to the master branch itself,
176 you also need to use the rebase feature in order to avoid an
177 unnecessary and distracting branch in master.
180 If it has been awhile since you've done the initial clone, try
185 to get the latest files before you start working.
188 Make your changes and use
190 git add
<files to commit
>
194 to get your changes ready to push back into the fd.o repository.
197 It is possible (and likely) that someone has changed master since
198 you did your last pull. Even if your changes do not conflict with
199 their changes, git will make a fast-forward
200 merge branch, branching from the point in time
201 where you did your last pull and merging it to a point after the other changes.
210 If you are familiar with CVS or similar system, this is similar to doing a
211 <code> cvs update
</code> in order to update your source tree to
212 the current repository state, instead of the time you did the last update.
213 (CVS doesn't work like git in this respect, but this is easiest way
216 In any case, your repository now looks like you made your changes after
217 all the other changes.
220 If the rebase resulted in conflicts or changes that could affect
221 the proper operation of your changes, you'll need to investigate
222 those before doing the push.
225 If you want the rebase action to be the default action, then
227 git config branch.master.rebase true
228 git config --global branch.autosetuprebase=always
231 See
<a href=

</a> for a fairly clear explanation about all of this.
