+<h2 id="extensions">Adding Extensions</h2>
<p>
To add a new GL extension to Mesa you have to do at least the following.
</pre>
</li>
<li>
- In the src/mesa/glapi/ directory, add the new extension functions and
+ In the src/mapi/glapi/gen/ directory, add the new extension functions and
enums to the gl_API.xml file.
Then, a bunch of source files must be regenerated by executing the
corresponding Python scripts.
</li>
<li>
Add a new entry to the <code>gl_extensions</code> struct in mtypes.h
+ if the extension requires driver capabilities not already exposed by
+ another extension.
</li>
<li>
- Update the <code>extensions.c</code> file.
+ Add a new entry to the src/mesa/main/extensions_table.h file.
</li>
<li>
From this point, the best way to proceed is to find another extension,
If the new extension adds new GL state, the functions in get.c, enable.c
and attrib.c will most likely require new code.
</li>
+<li>
+ To determine if the new extension is active in the current context,
+ use the auto-generated _mesa_has_##name_str() function defined in
+ src/mesa/main/extensions.h.
+</li>
+<li>
+ The dispatch tests check_table.cpp and dispatch_sanity.cpp
+ should be updated with details about the new extensions functions. These
+ tests are run using 'make check'
+</li>
</ul>

-<H2>Coding Style</H2>
-
-<p>
-Mesa's code style has changed over the years. Here's the latest.
-</p>
-
-<p>
-Comment your code! It's extremely important that open-source code be
-well documented. Also, strive to write clean, easily understandable code.
-</p>
-
-<p>
-3-space indentation
-</p>
-
-<p>
-If you use tabs, set them to 8 columns
-</p>
-
-<p>
-Brace example:
</p>
-<pre>
- if (condition) {
- foo;
- }
- else {
- bar;
- }
-</pre>
-<p>
-Here's the GNU indent command which will best approximate my preferred style:
-</p>
-<pre>
- indent -br -i3 -npcs --no-tabs infile.c -o outfile.c
-</pre>
-
-
-<p>
-Local variable name example: localVarName (no underscores)
-</p>
-
-<p>
-Constants and macros are ALL_UPPERCASE, with _ between words
-</p>
-
-<p>
-Global variables are not allowed.
-</p>
-
-<p>
-Function name examples:
-</p>
-<pre>
- glFooBar() - a public GL entry point (in glapi_dispatch.c)
- _mesa_FooBar() - the internal immediate mode function
- save_FooBar() - retained mode (display list) function in dlist.c
- foo_bar() - a static (private) function
- _mesa_foo_bar() - an internal non-static Mesa function
-</pre>

-<H2>Making a New Mesa Release</H2>
-
-<p>
-These are the instructions for making a new Mesa release.
-</p>
-
-<H3>Get latest source files</H3>
-<p>
-Use git to get the latest Mesa files from the git repository, from whatever
-branch is relevant.
-</p>
-
-
-<H3>Verify and update version info</H3>
-<p>
-Create/edit the docs/relnotes-x.y.html file to document what's new in the release.
-Add the new relnotes-x.y.html file to <a href="relnotes.html">relnotes.html</a>.
-</p>
-
-<p>
-Update the MESA_MAJOR, MESA_MINOR and MESA_TINY version numbers in
-configs/default.
-Also update the VERSION line in the top-level Makefile.
-</p>
-
-<p>
-Make sure the values in src/mesa/main/version.h are correct.
-</p>
-
-<p>
-Update docs/news.html.
-</p>
-
-<p>
-Check in all updates to git.
-</p>
-
-<p>
-Tag the files with the release name (in the form <b>mesa_X_Y</b>)
-with: <code>git tag -a mesa_X_Y</code>
-Then: <code>git push origin mesa_X_Y</code>
-</p>
-
-
-<H3>Make the tarballs</H3>
-<p>
-Make a symbolic link from $(DIRECTORY) to 'Mesa'. For example,
-<code>ln -s Mesa Mesa-7.5</code>
-This is needed in order to make a correct tar file in the next step.
-</p>
-
-<p>
-Make the distribution files. From inside the Mesa directory:
-<pre>
- make tarballs
-</pre>
-
-<p>
-After the tarballs are created, the md5 checksums for the files will
-be computed.
-Add them to the docs/relnotes-X.Y.html file.
-</p>
-
-<p>
-Copy the distribution files to a temporary directory, unpack them,
-compile everything, and run some demos to be sure everything works.
-</p>
-
-<H3>Update the website and announce the release</H3>
-<p>
-Follow the directions on SourceForge for creating a new "release" and
-uploading the tarballs.
-</p>
-
-<p>
-Basically, to upload the tarball files with:
-<br>
-<code>
-rsync -avP ssh Mesa*-X.Y.* USERNAME@frs.sourceforge.net:uploads/
-</code>
-</p>
-
-<p>
-Update the web site by copying the docs/ directory's files to
-/home/users/b/br/brianp/mesa-www/htdocs/ with:
-<br>
-<code>
-sftp USERNAME,mesa3d@web.sourceforge.net
-</code>
-</p>
-
-<p>
-Make an announcement on the mailing lists:
-<em>m</em><em>e</em><em>s</em><em>a</em><em>3</em><em>d</em><em>-</em><em>d</em><em>e</em><em>v</em><em>@</em><em>l</em><em>i</em><em>s</em><em>t</em><em>s</em><em>.</em><em>s</em><em>f</em><em>.</em><em>n</em><em>e</em><em>t</em>,
-<em>m</em><em>e</em><em>s</em><em>a</em><em>3</em><em>d</em><em>-</em><em>u</em><em>s</em><em>e</em><em>r</em><em>s</em><em>@</em><em>l</em><em>i</em><em>s</em><em>t</em><em>s</em><em>.</em><em>s</em><em>f</em><em>.</em><em>n</em><em>e</em><em>t</em>
-and
-<em>m</em><em>e</em><em>s</em><em>a</em><em>3</em><em>d</em><em>-</em><em>a</em><em>n</em><em>n</em><em>o</em><em>u</em><em>n</em><em>c</em><em>e</em><em>@</em><em>l</em><em>i</em><em>s</em><em>t</em><em>s</em><em>.</em><em>s</em><em>f</em><em>.</em><em>n</em><em>e</em><em>t</em>
