tells the scripts to assign an available offset to the function. The
important changes are in src/mesa/glapi/gl_XML.py and
src/mesa/glapi/*.xml.
Since the DRI drivers only depend on functions required by the ABI
(e.g., GL 1.2 + ARB_multitexture) having fixed offsets, all functions
not in the ABI use "assign" mode. This has caused the offset of
basically every function outside the ABI to change. I have verified
that a libGL with this patch works with a DRI driver without the patch.
Futher, several function were removed from the dispatch tables
altogether. These are the functions for the following extensions:
GL_SGIS_texture_filter4
GL_SGIS_texture4D
GL_SGIS_detail_texture
GL_SGIS_sharpen_texture
GL_SGIX_sprite
GL_SGIX_instruments
GL_SGIX_framezoom
GL_SGIX_tag_sample_buffer
GL_SGIX_reference_plane
GL_SGIX_flush_raster
GL_SGIX_list_priority
GL_SGIX_fragment_lighting
GL_PGI_misc_hints
GL_EXT_index_material
GL_EXT_index_func
GL_3DFX_tbuffer
This removes 50 functions from the dispatch table.
boolean attribute, which defaults to true, determines whether or not a
static dispatch function is available in libGL for applications to link
against.
Ideally, any new functions that are not part of the ABI should not have
directly accessable dispatch functions. This forces applications to use
glXGetProcAddress to access these functions. By doing this we can
gracefully remove functions from libGL without breaking the linkage of
applications.
Note that the static dispatch functions are still generated. However, they
are given names like gl_dispatch_stub_820 and are marked with the "hidden"
linker attribute.
All extension functions added since the previous Mesa release (6.5) have
been marked as 'static_dispatch="false"'.
GL_EXT_framebuffer_blit. Enumerants in the XML schema get the GL_ prefix
added to them automatically. This resulted in things like

Adding basic support to drivers should be as easy as just enabling the
extension, though thorough test would also be required.
signals to the script (glX_proto_size.py) that generates the server-side
size functions that a handcoded query is needed to determine the data size.
Also do s/FOG_COORD_SOURCE/FOG_COORD_SRC/.
When initializing the count in glx_enum::__init__, cast the local property
to int. Thanks to Python's dynamic typing, if this isn't done the type of
stored count will be a string instead of an int.
glTexImage3D that caused me so many problems during the re-development
of the API scripts reared its ugly head again. This has been fixed by
tracking the parameter string for each entry-point individually.
This has the annoying side-effect that the names of the parameters in
all aliases of a function must be the same or gl_apitemp.py will
generate bad code. :( The changes in
src/mesa/glapi/{gl_API.xml,glapitable.h} and src/glx/x11/* are caused
by fixing the parameter names in various function aliases that didn't
match.

src/mesa/glapi. Basically, the scripts that did simple things (like
gl_offsets.py) were simple, and the scripts that did more complicated things
(like glX_proto_send.py) were getting progressively more and more out of
control. So, I re-write the foundation classes on which everything is based.
One problem with the existing code is that the division between the GL API
database representation and the way the output code is generated was either
blury or nonexistant. The new code somewhat follows the
Model-View-Controller pattern, minus the Controller. There is a distinct
set of classes that model the API data, and there is a distinct set of
classes that generate code from that data.
One big change is in the class that represents GL functions (was glFunction,
is now gl_function). There used to be an instance of this calls for each
function and for each alias to that function. For example, there was an
instance for PointParameterivSGIS, PointParameterivEXT, PointParameterivARB,
and PointParameteriv. In the new code, there is one instance. Each
instance has a list of entrypoint names for the function. In the next
revision, this will allow a couple useful things. The script will be able
to verify that the parameters, return type, and GLX protocol for a function
and all it's aliases match.
It will also allow aliases to be represented in the XML more compactly.
Instead of repeating all the information, an alias can be listed as:
<function name="PointParameterivARB" alias="PointParameterivEXT"/>
Because the data representation was changed, the order that the alias
functions are processed by the scripts also changed. This accounts for at
least 2,700 of the ~3,600 lines of diffs in the generated code.
Most of the remaining ~900 lines of diffs are the result of bugs *fixed* by
the new scripts. The old scripts also generated code with some bugs in it.
These bugs were discovered while the new code was being written.
These changes were discussed on the mesa3d-dev mailing list back at the end

functions. There are two parts to this. First, a size element with a name
"Get" is shorthand for having four separate size elements with names
"GetIntegerv", "GetDoublev", "GetFloatv", and "GetBooleanv". Additionally,
a count of "?" is treated specially. This causes a call to a handcoded
function named "__gl<base name>_variable_size". This is *only* needed to
support GL_COMPRESSED_TEXTURE_FORMATS. That enum can return a variable
number of values depending how many compressed texture formats are supported
by the implementation.

for 1.5 support is ARB_vertex_buffer_object.
The opcodes for ARB_matrix_palette were also added to gl_API.xml. Since
this extension isn't supported by Mesa, no code is generated for it. Some

The attribute can now take one of 4 states. "false" (the default value)
means that no handcoding is required for the function. "client" means that
the function must be handcoded on the client-side only. "server" means that
the function must be handcoded on the server-side only. "true" menas that
the function must be handcoded on both the client-side and the server-side.

be removed completely from "size" sub-elements, so gl_API.xml was also
updated.
Support was added for a (currently unused) "mode" attribute for "size"
elements. Basically, functions are marked as either "get" or "set". This
will be used in generating size functions for the server-side (where the
"get" functions have to know how much data to return). It could also be

So, the ARB and NV version of VertexAttrib need to be distinct.
