XQueryExtension merely tells you whether the extension exists, it
doesn't tell you whether you're local enough for it to work.
XShmQueryVersion is not enough to discover this either, you need to
provoke the server to do actual work, and if it thinks you're remote it
will throw BadRequest at you. So send an invalid ShmDetach and use the

Meson test has a concepts of suites, which allow tests to be grouped
together. This allows for a subtest of tests to be run only (say only
the tests for nir). A test can be added to more than one suite, but for
the most part I've only added a test to a single suite, though I've
added a compiler group that includes nir, glsl, and glcpp tests.
To use this you'll need to invoke meson test directly, instead of ninja
test (which always runs all targets). it can be invoked as:
`meson test -C builddir --suite $suitename` (meson test has addition
options that are pretty useful).

GLXCreate{,New}Context, like most X resource creation requests, does not
emit a reply and therefore is emitted into the X stream asynchronously.
However, unlike most resource creation requests, the GLXContext we
return is a handle to library state instead of an XID. So if context
creation fails for any reason - say, the server doesn't support indirect
contexts - then we will fail in strange places for strange reasons.
We could make every GLX entrypoint robust against half-created contexts,
or we could just verify that context creation worked. Reuse the
__glXIsDirect code to do this, as a cheap way of verifying that the
XID is real.
glXCreateContextAttribsARB solves this by using the _checked version of
the xcb command, so effectively this change makes the classic context
creation paths as robust as CreateContextAttribs.

Since 6e06e281, the sRGBcapable flag is now actually compared, using
MATCH_DONT_CARE.
7b0f912e added defaulting of sRGBcapable to GL_FALSE in
__glXInitializeVisualConfigFromTags(), to handle servers which don't report
it, but this function is also used by glXChooseFBConfig(), so sRGBcapable is
implicitly false when not explicitly specified.
(This can cause e.g. glxinfo to fail to find anything matching the simple
config it looks for if all the candidates have the sRGB flag set to true.
I'm assuming this doesn't happen 'normally' as candidate configs with and
without sRGB true are available)

In the old days (0.42.x), when mesa's meson system was written the
recommendation for handling conditional dependencies was to define them
as empty lists. When meson would evaluate the dependencies of a target
it would recursively flatten all of the arguments, and empty lists would
be removed. There are some problems with this, among them that lists and
dependencies have different methods (namely .found()), so the
recommendation changed to use `dependency('', required : false)` for
such cases. This has the advantage of providing a .found() method, so
there is no need to do things like `dep_foo != [] and dep_foo.found()`,
such a dependency should never exist.
I've tested this with 0.42 (the minimum we claim to support) and 0.45.
On 0.45 this removes warnings about comparing unlike types, such as:
meson.build:1337: WARNING: Trying to compare values of different types
(DependencyHolder, list) using !=.

This does not implement glvnd (which is coming in a later patch)
Meson builds egl slightly differently than autotools, namely it doesn't
build an intermediate shared library. It doesn't do this because meson
doesn't have problems with the name of the library being dynamically
generated, so the glvnd and non-glvnd code can follow the same path.

Unconditionally enable xmlconfig and drop the linking. As said before

Unfortunately the check always checks the given config against

actual X-Screen specified in the config config->screen.
This leads to failure whenever a GL context is created
on a non-DefaultScreen(dpy), e.g., on X-Screen 1 of

* a Windows-DRI extension helper client library
* a Windows-specific DRI implementation for GLX clients
The server is queried for Windows-DRI extension support on the screen before
using it (to detect the case where WGL is disabled or can't be activated).
The server is queried for fbconfigID to pixelformatindex mapping, which is
used to augment glx_config.
The server is queried for a native handle for the drawable (which is of a
different type for windows, pixmaps and pbuffers), which is used to augment
__GLXDRIdrawable.
Various GLX extensions are enabled depending on if the equivalent WGL
extension is available.
Currently, due to the inverse order, strcmp will produce negative result
when the needle is towards the start of the haystack. Thus on the next

There is no draw arrays protocol support for multi-texture coordinate
arrays, so it is implemented by sending batches of immediate mode
commands from emit_element_none in indirect_vertex_array.c. This sends
the target texture unit (which has been previously setup in the
array_state header field), followed by the texture coordinates. But for
GL_DOUBLE coordinates the texture unit must be sent *after* the texture
coordinates. This is documented in the glx protocol description, and can
also be seen in the indirect.c immediate mode commands generated from
gl_API.xml. Sending the target texture unit in the wrong place can crash
the remote X server.
To fix this required some more extensive changes to
indirect_vertex_array.c and indirect_vertex_array_priv.h, in order to
remove the texture unit value out of the array_state "header" field, and
send it separately.

For each indirect context the indirect vertex array state must be initialised
by __glXInitVertexArrayState in indirect_vertex_array.c. As noted in the
routine header it requires that the glx context has been setup prior to the
call, in order to test the server version and extensions.
Currently __glXInitVertexArrayState is called from indirect_bind_context in
indirect_glx.c, as follows:
state = gc->client_state_private;
if (state->array_state == NULL) {
glGetString(GL_EXTENSIONS);
glGetString(GL_VERSION);
__glXInitVertexArrayState(gc);
}
But, the gc context is not yet usable at this stage, so the server queries
fail, and __glXInitVertexArrayState is called without the server version and
extension information it needs. This breaks multi-texturing as
glXInitVertexArrayState doesn't get GL_MAX_TEXTURE_UNITS. It probably also
breaks setup of other arrays: fog, secondary colour, vertex attributes.
To fix this I have moved the call to __glXInitVertexArrayState to the end of
MakeContextCurrent in glxcurrent.c, where the glx context is usable.
Fixes a regression caused by commit 4fbdde889c. Fixes ARB_vertex_program

The legacy swrast driver tracks when a front buffer is used

so this patch attempts to add the same functionality to the
gallium drivers.
It creates a new context interface to denote when a front

this pointer is then used to decide on map/unmap if the
contents should be updated from the real frontbuffer using

GLX_ARB_create_context_profile, support for the EXT was disabled if the
ARB was not supported.
This was complete rubbish. If the server supported the ARB but not the
EXT, sending a request with GLX_CONTEXT_ES2_PROFILE_BIT_EXT would result
in GLXBadProfileARB.

The code for emitting INTEL_swap_events swap completion
events needs to translate from 32-Bit sbc on the wire to
64-Bit sbc for the events and handle wraparound accordingly.
It assumed that events would be sent by the server in the
order their corresponding swap requests were emitted from
the client, iow. sbc count should be always increasing. This
was correct for DRI2.
This is not always the case under the DRI3/Present backend,
where the Present extension can execute presents and send out
completion events in a different order than the submission
order of the present requests, due to client code specifying
targetMSC target vblank counts which are not strictly
monotonically increasing. This confused the wraparound
handling. This patch fixes the problem by handling 32-Bit
wraparound in both directions. As long as successive swap
completion events real 64-Bit sbc's don't differ by more
than 2^30, this should be able to do the right thing.
How this is supposed to work:
awire->sbc contains the low 32-Bits of the true 64-Bit sbc
of the current swap event, transmitted over the wire.
glxDraw->lastEventSbc contains the low 32-Bits of the 64-Bit
sbc of the most recently processed swap event.
glxDraw->eventSbcWrap is a 64-Bit offset which tracks the upper
32-Bits of the current sbc. The final 64-Bit output sbc
aevent->sbc is computed from the sum of awire->sbc and
glxDraw->eventSbcWrap.
Under DRI3/Present, swap completion events can be received
slightly out of order due to non-monotic targetMsc specified
by client code, e.g., present request submission:
Submission sbc: 1 2 3
targetMsc: 10 11 9
Reception of completion events:
Completion sbc: 3 1 2
The completion sequence 3, 1, 2 would confuse the old wraparound
handling made for DRI2 as 1 < 3 --> Assumes a 32-Bit wraparound
has happened when it hasn't.
The client can queue multiple present requests, in the case of
Mesa up to n requests for n-buffered rendering, e.g., n = 2-4 in
the current Mesa GLX DRI3/Present implementation. In the case of
direct Pixmap presents via xcb_present_pixmap() the number n is
limited by the amount of memory available.
We reasonably assume that the number of outstanding requests n is
much less than 2 billion due to memory contraints and common sense.
Therefore while the order of received sbc's can be a bit scrambled,
successive 64-Bit sbc's won't deviate by much, a given sbc may be
a few counts lower or higher than the previous received sbc.
Therefore any large difference between the incoming awire->sbc and
the last recorded glxDraw->lastEventSbc will be due to 32-Bit
wraparound and we need to adapt glxDraw->eventSbcWrap accordingly
to adjust the upper 32-Bits of the sbc.
Two cases, correponding to the two if-statements in the patch:
a) Previous sbc event was below the last 2^32 boundary, in the previous
glxDraw->eventSbcWrap epoch, the new sbc event is in the next 2^32
epoch, therefore the low 32-Bit awire->sbc wrapped around to zero,
or close to zero --> awire->sbc is apparently much lower than the
glxDraw->lastEventSbc recorded for the previous epoch
--> We need to increment glxDraw->eventSbcWrap by 2^32 to adjust
the current epoch to be one higher than the previous one.
--> Case a) also handles the old DRI2 behaviour.
b) Previous sbc event was above closest 2^32 boundary, but now a
late event from the previous 2^32 epoch arrives, with a true sbc
that belongs to the previous 2^32 segment, so the awire->sbc of
this late event has a high count close to 2^32, whereas
glxDraw->lastEventSbc is closer to zero --> awire->sbc is much
greater than glXDraw->lastEventSbc.
--> We need to decrement glxDraw->eventSbcWrap by 2^32 to adjust
the current epoch back to the previous lower epoch of this late
completion event.
We assume such a wraparound to a higher (a) epoch or lower (b)
epoch has happened if awire->sbc and glxDraw->lastEventSbc differ
by more than 2^30 counts, as such a difference can only happen
on wraparound, or if somehow 2^30 present requests would be pending
for a given drawable inside the server, which is rather unlikely.
v2: Explain the reason for this patch and the new wraparound handling
much more extensive in commit message, no code change wrt. initial
version.

glXSwapBuffersMscOML() with target_msc=divisor=remainder=0 gets
translated into target_msc=divisor=0 but remainder=1 by the mesa
api. This is done for server DRI2 where there needs to be a way
to tell the server-side DRI2ScheduleSwap implementation if a call
to glXSwapBuffers() or glXSwapBuffersMscOML(dpy,window,0,0,0) was
done. remainder = 1 was (ab)used as a flag to tell the server to
select proper semantic. The DRI3/Present backend ignored this
signalling, treated any target_msc=0 as glXSwapBuffers() request,
and called xcb_present_pixmap with invalid divisor=0, remainder=1
combo. The present extension responded kindly to this with a
BadValue error and dropped the request, but mesa's DRI3/Present
backend doesn't check for error codes. From there on stuff went
downhill quickly for the calling OpenGL client...
This patch fixes the problem.

Prevent calls to glXGetSyncValuesOML() and glXWaitForMscOML()
from overwriting the (ust,msc) values of the last successfull
swapbuffers call (PresentPixmapCompleteNotify event), as
glXWaitForSbcOML() relies on those values corresponding to
the most recent completed swap, not to whatever was last
returned from the server.
Problematic call sequence without this patch would have been, e.g.,
glXSwapBuffers()
... wait ...
swap completes -> PresentPixmapComplete event -> (ust,msc)
updated to reflect swap completion time and count.
... wait for at least 1 video refresh cycle/vblank increment.
glXGetSyncValuesOML()
-> PresentNotifyMsc event overwrites (ust,msc) of swap
completion with (ust,msc) of most recent vblank
glXWaitForSbcOML()
-> Returns sbc of last completed swap but (ust,msc) of last
completed vblank, not of last completed swap.
-> Client is confused.
Do this by tracking a separate set of (ust, msc) for the
dri3_wait_for_msc() call than for the dri3_wait_for_sbc()
call.
This makes the glXWaitForSbcOML() call robust again and restores
consistent behaviour with the DRI2 implementation.
Fixes applications originally written and tested against
DRI2 which also rely on this not regressing under DRI3/Present,
e.g., Neuro-Science software like Psychtoolbox-3.
This patch fixes the problem.

The current implementation of glxUseXFont requires creating
a temporary pixmap and graphics context, which requires a real
old-school X11 Window, not a glxDrawable. This patch changes
things so that glxUseXFont will also accept a glxWindow or
glxPixmap, and lookup the underlying X11 Drawable. Without
this patch glxUseXFont generates a giant stream of Xerrors
about bad drawables and bad graphics contexts.

Instead of just segfaulting in the driver when a buffer allocation fails,
report error messages indicating what went wrong so that we can debug things.
As a simple example, chromium wraps Mesa in a sandbox which doesn't allow
access to most syscalls, including the ability to create shared memory
segments for fences. Before, you'd get a simple segfault in mesa and your 3D
acceleration would fail. Now you get:

A driver which doesn't have async flip support will queue up flips without any
way to replace them afterwards. This means we've got a scanout buffer pinned
as soon as we schedule a flip and so we need another buffer to keep from
stalling.
When vblank_mode=0, if there are only three buffers we do:
current scanout buffer = 0 at MSC 0
Render frame 1 to buffer 1
PresentPixmap for buffer 1 at MSC 1
This is sitting down in the kernel waiting for vblank to
become the next scanout buffer
Render frame 2 to buffer 2
PresentPixmap for buffer 2 at MSC 1
This cannot be displayed at MSC 1 because the
kernel doesn't have any way to replace buffer 1 as the pending
scanout buffer. So, best case this will get displayed at MSC 2.
Now we block after this, waiting for one of the three buffers to become idle.
We can't use buffer 0 because it is the scanout buffer. We can't use buffer 1
because it's sitting in the kernel waiting to become the next scanout buffer
and we can't use buffer 2 because that's the most recent frame which will
become the next scanout buffer if the application doesn't manage to generate
another complete frame by MSC 2.
With four buffers, we get:
current scanout buffer = 0 at MSC 0
Render frame 1 to buffer 1
PresentPixmap for buffer 1 at MSC 1
This is sitting down in the kernel waiting for vblank to
become the next scanout buffer
Render frame 2 to buffer 2
PresentPixmap for buffer 2 at MSC 1
This cannot be displayed at MSC 1 because the
kernel doesn't have any way to replace buffer 1 as the pending
scanout buffer. So, best case this will get displayed at MSC
2. The X server will queue this swap until buffer 1 becomes
the scanout buffer.
Render frame 3 to buffer 3
PresentPixmap for buffer 3 at MSC 1
As soon as the X server sees this, it will replace the pending
buffer 2 swap with this swap and release buffer 2 back to the
application
Render frame 4 to buffer 2
PresentPixmap for buffer 2 at MSC 1
Now we're in a steady state, flipping between buffer 2 and 3
waiting for one of them to be queued to the kernel.
...
current scanout buffer = 1 at MSC 1
Now buffer 0 is free and (e.g.) buffer 2 is queued in
the kernel to be the scanout buffer at MSC 2
Render frames, flipping between buffer 0 and 3
When the system can replace a queued buffer, and we update Present to take
advantage of that, we can use three buffers and get:
current scanout buffer = 0 at MSC 0
Render frame 1 to buffer 1
PresentPixmap for buffer 1 at MSC 1
This is sitting waiting for vblank to become the next scanout
buffer
Render frame 2 to buffer 2
PresentPixmap for buffer 2 at MSC 1
Queue this for display at MSC 1
1. There are three possible results:
1) We're still before MSC 1. Buffer 1 is released,
buffer 2 is queued waiting for MSC 1.
2) We're now after MSC 1. Buffer 0 was released at MSC 1.
Buffer 1 is the current scanout buffer.
a) If the user asked for a tearing update, we swap
scanout from buffer 1 to buffer 2 and release buffer
1.
b) If the user asked for non-tearing update, we
queue buffer 2 for the MSC 2.
In all three cases, we have a buffer released (call it 'n'),
ready to receive the next frame.
Render frame 3 to buffer n
PresentPixmap for buffer n
If we're still before MSC 1, then we'll ask to present at MSC
1. Otherwise, we'll ask to present at MSC 2.
Present already does this if the driver offers async flips, however it does
this by waiting for the right vblank event and sending an async flip right at
that point.
I've hacked the intel driver to offer this, but I get tearing at the top of
the screen. I think this is because flips are always done from within the
ring, and so the latency between the vblank event and the async flip happening
can cause tearing at the top of the screen.
That's why I'm keying the need for the extra buffer on the lack of 2D
driver support for async flips.
