glDeleteTextures and glDeleteTexturesEXT were erroneously listed as
aliases of each other. For anything /except/ GLX protocol they are
aliases. This set of changes allows functions that are functionally
identical but have different GLX protocol to be listed as aliases.
When building with GLX_INDIRECT_RENDERING set, different static
functions are used. These functions determine whether the current
context is direct rendering or not. If the context is direct
rendering, the aliased function (e.g., glDeleteTextures in the case of
glDeleteTexturesEXT) is called. If the context is not direct
rendering, the correct GLX protocol is sent.
For a deeper explanation of what is changed, please see:

Nvidia no longer supports this extension, and they no longer export its
entry points from their libGL. There's no reason for us to keep dragging it
around either.

Make functions for the following extensions available only via
glXGetProcAddress. In cases where there are other aliases to the same
functions (e.g., between GL_EXT_histogram and GL_ARB_imaging), the alias
functions may still be statically exported.
- GL_ATI_blend_equation_separate
- GL_EXT_blend_equation_separate
- GL_EXT_convolution
- GL_EXT_color_sub_table
- GL_EXT_cull_vertex
- GL_EXT_depth_bounds_test
- GL_EXT_framebuffer_blit
- GL_EXT_histogram
- GL_EXT_multisample
- GL_EXT_stencil_two_side
- GL_EXT_timer_query
- GL_IBM_multimode_draw_arrays
- GL_INGR_blend_func_separate
- GL_NV_fence
- GL_SGI_color_table
- GL_SGIS_multisample
- GL_SGIS_pixel_texture
- GL_SGIS_point_parameters
- GL_SGIX_pixel_texture

glBlendEquationSeparateEXT. Add missing enum "get" information for
GL_EXT_texture_filter_anisotropic.
|
|
The functions for GL_EXT_paletted_texture that do not share GLX
protocol with GL_ARB_imaging are supposed to alias the similar
functions from GL_SGI_color_table. They didn't. This patch corrects
this problem and enables GLX protocol for both extensions.
Since this removes 3 entries from the dispatch table, this change
creates a lot of changes in the generated files.

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"'.

either GL_ARB_vertex_program or GL_ARB_fragment_program should enable this

Adding basic support to drivers should be as easy as just enabling the
extension, though thorough test would also be required.

Remove _glapi_DispatchTSD and give _glapi_Dispatch its semantic (i.e.,
having a NULL value means that the application is multithreaded and
_glapi_get_dispatch must be called).
Gut all of the dispatch override code. This removes _glapi_RealDispatch,
_glapi_tls_RealDispatch, _glapi_begin_dispatch_override,
_glapi_end_dispatch_override, and _glapi_get_override_dispatch.
Remove _glapi_get_proc_address, _glapi_get_proc_name, _glapi_get_version,
and _glapi_check_table from the loader / driver interface.

1,402 lines of code to be removed from Mesa (drivers and libGL). The
big winner is dri_util.c.
Primary changes are:
1. Remove all "deprecated" entry-points from the various structures in
dri_interface.h.
2. Rename the remaining fields to removed "version numbers." So,
bindContext3 becomes bindContext. Functions with "New" in the name
(e.g., CreateNewContext) were *not* changed, but that is an option.
Having "New" in the name is less annoying to me than having "3" in the name.
3. Remove all compatibility code that handles cases where the driver or
the loader is too old to support the latest interfaces.
4. Append the API version to the __driCreateNewScreen function name.
This is currently done by hand. In the future (i.e., the next time we
make an incompatible change to the interface) we'll want to come up with
a better way to do this. This prevents old loaders from being able to load
new (incompatible) drivers.
5. Bump the API version to 20050722. All drivers (by way of dri_util.c)
require this version.
6. All drivers are *required* to expose GLX_SGIX_fbconfig and
GLX_OML_swap_method (or the moral equivalents). Support for these
functions in implicit in the use of the "new" interface.
7. Some cases still exist that need to be compiled differently in a loader
or core Mesa versus in a driver. These are identified by the define
IN_DRI_DRIVER.

Pixel count can be negative (this could be fixed elsewhere), so adapt the

functions).

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
of May:
