2009-08-25Revert "glapi: Fix a possible race in getting current context/dispatch."Brian Paul
This reverts commit 17090cf3efb0db8fa01b502a9c0df27cbd1a67da. We're reverting this because it causes ABI breakage with the X server. Maybe re-attempt with another patch.
2009-08-24glapi: Fix a possible race in getting current context/dispatch.Chia-I Wu
There is a possbile race that _glapi_Context is reset by another thread after it is tested in GET_CURRENT_CONTEXT but before it is returned. We definitely do not want a lock here to solve the race. To have correct results even under a race, no other threads should reset _glapi_Context (or _glapi_Dispatch). This patch adds a new global variable _glapi_SingleThreaded. Since _glapi_Context or _glapi_Dispatch are no longer reset, _glapi_SingleThreaded is tested instead, before accessing them. DRI drivers compiled with this patch applied will not work with existing libGL.so because of the missing new symbol. If this turns out to be a real problem, this patch should be reverted.

2006-06-16Thread safety for Win32. SourceForge bug #1507315.Brian Paul
2005-08-10Remove _glapi_check_multithread from the interface exported by the loader toIan Romanick
the driver. The loader now takes care of this for the driver. 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. Reviewed by: Brian Paul
2005-08-03Convert all instances of XTHREADS to USE_XTHREADS. This fixes one ofIan Romanick
serveral things that are broken when building on a system with X.org 7.0rc0 installed.
2005-07-18Wrap every place that accesses a dispatch table with a macro. A new script-Ian Romanick
generated file, called src/mesa/glapi/dispatch.h, is added. This file contains three macros for each API function. It contains a GET, a SET, and a CALL. Each of the macros take a pointer to the context and a pointer to the dispatch table. In several threads on mesa3d-dev we discussed replacing _glapi_add_entrypoint with a new function called _glapi_add_dispatch. For this discussion, the important difference between the two is that the caller of _glapi_add_dispatch does *not* know what the dispatch offset will be at compile time. Because of this callers need to track the dispatch offset returned by _glapi_add_dispatch. http://marc.theaimsgroup.com/?t=111947074700001&r=1&w=2 The downside is that driver code then has to access the dispatch table two different ways. It accesses it using structure tags (e.g., exec->Begin) for functions with fixed offsets and via a remap table (e.g., exec[ remap->NewExtensionFunction ]) for functions without fixed offsets. Yuck! Using the macros allows both types of functions to be accessed identically. If a driver needs to set a pointer for Begin, it does 'SET_Begin(ctx, exec, my_begin_function)'. If it needs to set a pointer for NewExtensionFunction, it does 'SET_NewExtensionFunction(ctx, exec, my_NewExtensionFunction_function)'. Furthermore, if at some point in the future a static offset is assigned for NewExtensionFunction, only the macros need to change (instead of every single place that accesses a table for that function). This code differs slightly from the originally posted patches in that the CALL, GET, and SET marcos no longer take a context pointer as a parameter. Brian Paul had suggested that the remap table could be stored as a global since it would be set at CreateScreen time and would be constant for all contexts. This change reflects that feedback. http://marc.theaimsgroup.com/?t=112087194700001&r=1&w=2
2005-04-14In GLX_USE_TLS builds, make GET_CURRENT_CONTEXT use the TLS verion of theIan Romanick
variable. Without this, GET_CURRENT_CONTEXT would *always* result in a call to _glapi_get_context (because _glapi_Context is a const pointer to NULL in TLS builds).
2005-04-13Add TLS support to libGL and, by virtue of using glthread.h and GL_CALL, allIan Romanick
DRI drivers. A TLS enabled libGL can load a TLS or a non-TLS DRI driver, but a TLS DRI driver requires a TLS enabled libGL. This fixes bug #1822.

2004-08-14BeOS's _glthread_DECLARE_STATIC_MUTEX() couldn't be used outside a functionPhilippe Houdoin
because she called create_sem(). Now the semaphore creation is made at first _glthread_LOCK_MUTEX() call.
2004-06-29First phase of TLS work. At this point SPARC assembly dispatch isIan Romanick
broken, but it will be fixed "shortly." This is pretty much the same as the patch I sent to the dri-devel list on 22-Jun-2004.

2001-11-30Corrected bad line breaks in macro definitions within code compiledKarl Schultz
when BEOS_THREADS is defined. This usually does not cause a problem when BEOS_THREADS is not defined, but the bad line break in this case put the "#name" text as the first non-white space in a line, causing the IRIX C preprocessor to think that it was a preprocessor directive, and that generated a distracting warning. I also fixed a couple of other line breaks that seemed wrong to me.
