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.

Doing this here rather than on the GLX side since the X monolith hasn't had
Mesa 6.3 imported yet.
idr, I know this is touching a generated file, but I haven't figured out what
needs changing in the generator scripts to make this change happen. If you
could add that I'd appreciate it.

is basically patch #2939 from X.org bugzilla #3379. This does *not*
fix the bug as it does not dynamically generate stubs at run-time. It
just gets things one step closer.

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
of May:

(eventual) addition of support for ARB_vertex_buffer_object. Elminitate the

Move all the private vertex array data structures out of
indirect_vertex_array.c and into indirect_va_private.h.
Rename array_state_vector::enabled_array_count to
array_state_vector::enabled_client_array_count.
Make sure that both the GL extension string and the server GL version are
available when __glXInitVertexState is called.
Make sure that array_state::normalized is set correctly in the array's
gl*Pointer function.

Remove the 'ignore="true"' from glVertexAttrib4bvARB. This fixes bugzilla
#2746.

some flaws in the calculation code when the highest version listed in
known_gl_extensions is supported. This code would also have some problems
with some of the new features (that don't have an associated extension) on
GL 2.0.

for these extensions (as well as ARB_vertex_program and ARB_matrix_palette)
was just approved by the ARB on 8-Mar-2005. Now the only extension missing
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
tabs were also converted to spaces in the comment for
GetCompressedTexImageARB.

setup_single_request, and setup_vendor_request to the global functions
__glXReadPixelReply, __glXReadReply, __glXSetupSingleRequest, and

Fixed a flow control problem in glGet*v that could result in the display
not being unlocked. This also resulted in refactoring a lot more code
out of the glGet*v routines into get_array_data, which was renamed to
get_client_data.

enables libGL to query which extension are exported to applications.
Refactored array-query functionality (from glGet*v) in src/glx/x11/single2.c.
Massive re-write of indirect vertex array support. The most noticable
effect is that glDrawElements now generates DrawArrays protocol. The
side-effects (and the main reasons for the re-work) are that it is much
easier to add support for new arrays (e.g., GL_VERTEX_ATTRIB_ARRAY,
GL_WEIGHT_ARRAY_ARB, etc.) and it is much easier to add support for the new
DrawArrays protocol (required to support ARB_vertex_buffer_object).
These changes were primarilly tested with progs/demos/isosurf.

FilterGLAPISpecBase. Since the size_h mode of glX_proto_size.py will be
used to generate multiple header files, add an option to specify the define

The changes to the header files in this commit are just a side-effect of the
changes to the Python scripts.

Correct the protocol for EXT_convolution. Several functions were
incorrectly listed as 'sop' that should have been 'vendorpriv'.
Remove TexParameter[if]v from the list of functions associated with
TEXTURE_RESIDENT. The state associated with this enum is read-only.
Sort the enums by value for each particular size. This ensures that the
signature is the same no matter what the ordering is of the enums in the XML
file. The side effect is that there are some extra changes in
indirect_size.c.
