[Chromium-users] crServerlib funny behaviour

[Daniel E. S. <dan...@gm...>]

Hello all,

I have an application that is processing the crServer loop by hand.  It
looks like so...
NOTE: has_swapped gets set to 1 when glXSwapBuffers is seen within the
stream.
           also, the glEnables are to explain my example

      // Draw graphics off the GL stream
      glPushMatrix();
         glEnable(GL_LIGHTING);
         glEnable(GL_LIGHTING);
         glEnable(GL_LIGHTING);
         while (cr_server.has_swapped != 1)
         {
            if(cr_server.run_queue != NULL)
            {
               crServerServiceClients();
            }
         }
         cr_server.has_swapped = 0;
         glDisable(GL_LIGHTING);
         glDisable(GL_LIGHTING);
         glDisable(GL_LIGHTING);
      glPopMatrix();

When the code is compiled and ran the buGLe log shows:

trace.call: glPushMatrix()
trace.call: glEnable(GL_LIGHTING)
trace.call: glEnable(GL_LIGHTING)
trace.call: glEnable(GL_LIGHTING)     <-- Over the wire drawing should begin
here.
trace.call: glDisable(GL_LIGHTING)
trace.call: glDisable(GL_LIGHTING)
trace.call: glDisable(GL_LIGHTING)
trace.call: glPopMatrix()
trace.call: glPushAttrib(GL_ALL_ATTRIB_BITS)   <-- but begins here...
trace.call: glGetBooleanv(GL_LIGHTING, 0x43c06bbb -> GL_FALSE)
trace.call: glGetBooleanv(GL_LIGHT0, 0x43c06bba -> GL_TRUE)
trace.call: glMaterialfv(GL_FRONT, GL_AMBIENT, 0x43c06ba0 -> { 0.1, 0.1, 0.1,
1 })
trace.call: glMaterialfv(GL_FRONT, GL_SHININESS, 0x43c06b90 -> 50)
trace.call: glMaterialfv(GL_FRONT, GL_SPECULAR, 0x43c06b70 -> { 1, 1, 1, 1
})
trace.call: glMaterialfv(GL_FRONT, GL_DIFFUSE, 0x43c06b80 -> { 0.7, 0.7, 0.7,
1 })
trace.call: glColorMaterial(GL_FRONT_AND_BACK, GL_AMBIENT_AND_DIFFUSE)
trace.call: glEnable(GL_COLOR_MATERIAL)
trace.call: glDisable(GL_TEXTURE_2D)
trace.call: glDisable(GL_TEXTURE_1D)
trace.call: glPushMatrix()
trace.call: glLoadIdentity()
trace.call: glBegin(GL_LINES)
trace.call: glColor3f(1, 0, 0)
trace.call: glVertex3fv(0x43c06b30 -> { 0, 0, 0 })
trace.call: glVertex3fv(0x43c06b60 -> { 3.28, 0, 0 })
trace.call: glColor3f(0, 1, 0)
trace.call: glVertex3fv(0x43c06b30 -> { 0, 0, 0 })
.....

I tried calling getNextClient with GL_TRUE (block)...but it had no effect.

So my question is how to make sure that the stream has been deserialized
into GL calls before I can continue making GL calls?
