Description Jin Yang 2011-08-10 22:18:49 UTC 
My program works fine with 7.9.2 and fails with 7.10.3.
In mesa 7.10.3, in teximage.c it will call _mesa_CompressedTexImage2DARB->
-> compressedteximage --> compressed_texture_error_check-->_mesa_is_compressed_format
, it will return error because format GL_PALETTE8_RGBA8_OES, then will not goto FEATURE_ES.

{
   error = compressed_texture_error_check(ctx, dims, target, level,
                                          internalFormat, width, height, depth,
                                          border, imageSize, &reason);

   if (error) {
      _mesa_error(ctx, error, "glCompressedTexImage%uD(%s)", dims, reason);
      return;
   }

#if FEATURE_ES
   /* XXX this is kind of a hack */
   if (dims == 2) {
      switch (internalFormat) {
      case GL_PALETTE4_RGB8_OES:
      case GL_PALETTE4_RGBA8_OES:
      case GL_PALETTE4_R5_G6_B5_OES:
      case GL_PALETTE4_RGBA4_OES:
      case GL_PALETTE4_RGB5_A1_OES:
      case GL_PALETTE8_RGB8_OES:
      case GL_PALETTE8_RGBA8_OES:
      case GL_PALETTE8_R5_G6_B5_OES:
      case GL_PALETTE8_RGBA4_OES:
      case GL_PALETTE8_RGB5_A1_OES:
         _mesa_cpal_compressed_teximage2d(target, level, internalFormat,
                                          width, height, imageSize, data);
         return;
      }
   }
}

In mesa 7.9.2, it will call _mesa_CompressedTexImage2DARB, and just goto _mesa_cpal_compressed_teximage2d and do the right thing.

 _mesa_CompressedTexImage2DARB {
   GET_CURRENT_CONTEXT(ctx);
   ASSERT_OUTSIDE_BEGIN_END_AND_FLUSH(ctx);

   if (MESA_VERBOSE & (VERBOSE_API|VERBOSE_TEXTURE))
      _mesa_debug(ctx, "glCompressedTexImage2DARB %s %d %s %d %d %d %d %p\n",
                  _mesa_lookup_enum_by_nr(target), level,
                  _mesa_lookup_enum_by_nr(internalFormat),
                  width, height, border, imageSize, data);

#if FEATURE_ES
   switch (internalFormat) {
   case GL_PALETTE4_RGB8_OES:
   case GL_PALETTE4_RGBA8_OES:
   case GL_PALETTE4_R5_G6_B5_OES:
   case GL_PALETTE4_RGBA4_OES:
   case GL_PALETTE4_RGB5_A1_OES:
   case GL_PALETTE8_RGB8_OES:
   case GL_PALETTE8_RGBA8_OES:
   case GL_PALETTE8_R5_G6_B5_OES:
   case GL_PALETTE8_RGBA4_OES:
   case GL_PALETTE8_RGB5_A1_OES:
      _mesa_cpal_compressed_teximage2d(target, level, internalFormat,
				       width, height, imageSize, data);
      return;
   }
#endif
}
Comment 1 Ian Romanick 2011-08-16 14:42:37 UTC 
We do not and never have supported that extension.  If an application uses that extension without first checking for it, that application is broken.
Comment 2 Jin Yang 2011-08-16 18:18:51 UTC 
Why this function works in Mesa 7.9.2. And from the code we can see it support GL_PALETTE8_RGBA8_OES if FEATURE_ES.
From OpenGLES.1x spec, this function and texture format is not extension and should be at least supported:
http://www.khronos.org/opengles/documentation/opengles1_0/html/glCompressedTexImage2D.html

Comment 3 Ian Romanick 2011-08-16 19:18:14 UTC 
Wow.  I can't believe how broken OpenGL ES 1.x is.  I also have a hard time caring.

Can you set a breakpoint here and give a full backtrace (i.e., 'bt full' in gdb)?  OpenGL ES 1.x only supports 2D textures, so dims should always be 2 here.

The full backtrace at that line is as follow, please note for project reason, frame below 2 is not attached:

The dims is 2. Thanks!

Comment 6 Jin Yang 2011-09-11 23:06:36 UTC 
The Key point is that in compression format check function:
compressed_texture_error_check
there is no support for ES and will return error.
Actually it does support in Mesa, see code block if #FEATURE_ES.

In verison 7.9.2, there is no format check funcion:compressed_texture_error_check
and it will goto code block if #FEATURE_ES.

Waiting for your reply,
Thanks

Comment 7 Ian Romanick 2011-09-13 15:45:08 UTC 
I just posted a patch series to the mesa-dev mailing list that should fix this issue.  Could you verify it?  It is also available in a branch in my personal GIT repo.

Verified, it works, thanks!
Comment 9 Ian Romanick 2011-09-19 10:05:52 UTC 
This should be fixed as of commit 3ebbfc8372d410801c799b3eb7821075dae73b17 in Mesa master.
