Developer git Access

-Mesa developers need to first have an account on -freedesktop.org. -To get an account, please ask Brian or the other Mesa developers for -permission. -Then, if there are no objections, follow this - -procedure. +If you wish to become a Mesa developer with git-write privilege, please +follow this procedure:

Subscribe to the +mesa-dev +mailing list. +
Start contributing to the project by +submitting patches to +the mesa-dev list. Specifically, +
- Use git send-mail to post your patches to mesa-dev. +
- Wait for someone to review the code and give you a Reviewed-by +statement. +
- You'll have to rely on another Mesa developer to push your initial patches +after they've been reviewed. +
+
After you've demonstrated the ability to write good code and have had +a dozen or so patches accepted you can apply for an account. +
Occasionally, but rarely, someone may be given a git account sooner, but +only if they're being supervised by another Mesa developer at the same +organization and planning to work in a limited area of the code or on a +separate branch. +
To apply for an account, follow +these directions. +It's also appreciated if you briefly describe what you intend to do (work +on a particular driver, add a new extension, etc.) in the bugzilla record. +

+ +

+Once your account is established, you can update your push url to use SSH: +

+git remote set-url --push origin git@gitlab.freedesktop.org:mesa/mesa.git
+

+ +You can also use personal access tokens +to push over HTTPS instead (useful for people behind strict proxies). +In this case, create a token, and put it in the url as shown here: +

+git remote set-url --push origin https://USER:TOKEN@gitlab.freedesktop.org/mesa/mesa.git
+

+ + +

Windows Users

-Once your account is established: +If you're +using git on Windows you'll want to enable automatic CR/LF conversion in +your local copy of the repository:

+   git config --global core.autocrlf true
+

Install the git software on your computer if needed.

-
Get an initial, local copy of the repository with: -
```
-    git clone git+ssh://username@git.freedesktop.org/git/mesa/mesa
-    
```
- Replace username with your actual login name.

-
Later, you can update your tree from the master repository with: -
```
-    git pull origin

+This will cause git to convert all text files to CR+LF on checkout, +and to LF on commit. +

+Unix users don't need to set this option. +

Developer Git Tips

Setting up to edit the master branch +

+If you try to do a pull by just saying git pull +and git complains that you have not specified a +branch, try: +

+    git config branch.master.remote origin
+    git config branch.master.merge master
+

+Otherwise, you have to say git pull origin master +each time you do a pull. +

Small changes to master +
+If you are an experienced git user working on substantial modifications, +you are probably +working on a separate branch and would rebase your branch prior to +merging with master. +But for small changes to the master branch itself, +you also need to use the rebase feature in order to avoid an +unnecessary and distracting branch in master. +
+
+If it has been awhile since you've done the initial clone, try +
```
+    git pull
+
```
+
+to get the latest files before you start working. +
+
+Make your changes and use +
```
+    git add <files to commit>
+    git commit
+
```
+
+to get your changes ready to push back into the fd.o repository. +
+
+It is possible (and likely) that someone has changed master since +you did your last pull. Even if your changes do not conflict with +their changes, git will make a fast-forward +merge branch, branching from the point in time +where you did your last pull and merging it to a point after the other changes. +
+
+To avoid this, +
```
+    git pull --rebase
+    git push
+
```
+
+If you are familiar with CVS or similar system, this is similar to doing a + cvs update in order to update your source tree to +the current repository state, instead of the time you did the last update. +(CVS doesn't work like git in this respect, but this is easiest way +to explain it.) +
+
+In any case, your repository now looks like you made your changes after +all the other changes. +
+
+If the rebase resulted in conflicts or changes that could affect +the proper operation of your changes, you'll need to investigate +those before doing the push. +
+
+If you want the rebase action to be the default action, then +
```
+    git config branch.master.rebase true
+    git config --global branch.autosetuprebase=always
+
```
+
+See Understanding Git Conceptually for a fairly clear explanation about all of this. +
