The problem here is that GlxInitVisuals is called twice. First via
fbScreenInit and then again via nxagentInitGlxExtension. We remove the
first one to ensure the code in nxagenOpenScreen works as initially
intended.
There's an xorg upstream patch that does the same
(7d74690536b64f7b8e8036507ab7790807349c50), but it also cleans up
other stuff we do not even have in out source (yet?).

This patch is not necessary at the current code level. But when xkb
code introduced the dev->key check Xorg upstream missed that. So we
backport it now to skip that trap when updating xkb code.

CloseDevice: call XkbRemoveResourceClient before freeing key class struct
XkbRemoveResourceClient() returns immediately if dev->key is NULL.
CloseDevice calls XkbRemoveResourceClient until it removes all resources.
If we free dev->key and NULL it before XkbRemoveResourceClient, then
infinite loop ensues, and the server appears to hang on exit or crash.

While trying to properly free memory allocated by XKB I accidently
called nxagentFreeKeyboardDeviceData twice and noticed it would cause
a segfault here. As the other pointers are also nullified after
being freed let's just do it here, too.

Fixes ArcticaProject/nx-libs#598
In nxagentOpenScreen we first initialized the RRExtension for the
screen and then replaced pScreen->CloseScreen by
nxagentCloseScreen. This resulted in RandR's RRCloseScreen (and any
other CloseScreen procedure installed by extensions) being no longer
called.
Moving RandR init after configuring pScreen->CloseScreen ensures the
correct calling cascade:
RRCloseScreen -> nxagentCloseScreen ->fbCloseScreen (called explicitly
by nxagentCloseScreen).
Which in turn will fix this memory leak:

They were just aliases to already existing defines and were not used
stringently. So we had mix of aliased and non-aliased uses which is
confusing when trying to understand the code...

This was eventually replaced by nxagentAddConfiguredWindow(pWin,
CW_Map) some lines below which is just leading to the same code being
executed some time later.
(nxagentAddConfiguredWindow() will add a window to a
list. nxagentFlushConfiguredWindow() is called at certain points to
update all windows in that list in one go. "update" here means calling
XConfigureWindow() or XMapWindow() on the real display.)

The only left function is identical to the one in mi/miexpose.c.

We do not even know what theme this is and it is probably not relevant
nowadays.

miPaintWindow() was identical to the version in miexpose.c except
for some unitialized variable fixes. As these also should be in
upstream code we add them there (Note: Xorg never fixed this but
totally rewrote the miPaintWindow() later on.)
This allows us to totally drop our special version of miPaintWindow().
|
|
|
|
|
| |
It is (functionally) identical to our code, so why have
duplicate code?

removed, tough...
commit c80c41767eb101e9dbd8393d8cca7764b4e248a4

os: Fix BigReq ignoring when another request is pending
Commit cf88363db0ebb42df7cc286b85d30d7898aea840 fixed the handling of
BigReq requests that are way too large and handles the case where the
read() syscall returns a short read. However, it neglected to handle
the case where it returns a long read, which happens when the client
has another request in the queue after the bogus large one.
Handle the long read case by subtracting the smaller of 'needed' and
'gotnow' from oci->ignoreBytes. If needed < gotnow, simply subtract
the two, leaving gotnow equal to the number of extra bytes read.
Since the code immediately following the (oci->ignoreBytes > 0) block
tries to handle the next request, advance oci->bufptr immediately
instead of setting oci->lenLastReq and letting the next call to
ReadRequestFromClient do it.
Fixes the XTS pChangeKeyboardMapping-3 test.
