* Xserver/GL/glx/glxcmds.c: Cast small-int values through intptr_t when passed ↵Mike Gabriel2017-12-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | as pointers Picked from this X.org commit: commit b0dd6be2c8703f7062d45ac9fd646550c7d54e3b Author: Jamey Sharp <jamey@minilop.net> Date: Thu Oct 8 13:38:44 2009 +1100 Cast small-int values through intptr_t when passed as pointers On 64-bit systems, int and pointers don't have the same size, so GCC gives warnings about casts between int and pointer types. However, in the cases covered by this patch, it's always a value that fits in int being stored temporarily as a pointer and then converted back later, which is safe. Casting through the pointer-sized integer type intptr_t convinces the compiler that this is OK.

* Xserver/os/xprintf.c: Drop NoMachine's own implementation of Xvasprintf(). ↵Mike Gabriel2017-12-111-50/+1
| | | | | | | | | | | | | | | | | | | | | | Use stock implementation instead. * Reason from NoMachine's NX CHANGELOG for having its own implementation of Xvasprintf() (from around nxagent 3.3.0): - Fixed TR06G02225. The implementation of Xvprintf() has been reviewed to work on more platforms. Previous implementation caused a failure in the build of keyboard map on some platform like Solaris 8 and 9. - Fixed TR03G02198. Reimplemented Xvprintf() in Xserver/os to handle the case in which vsnprintf returned -1. * Reason for removing it again: - Fixes segfaults in SetDefaultFontPath when launching nxagent. - All locations in Xserver/** using the code check for return value of -1. - Solaris 8 and 9 are beyond of our support scope. - Keep more in sync with X.org. - Good moment to drop more GPL-2 code from Xserver's code base.

If the platform provides vasprintf() we simply wrap it, otherwise we implement it - either way callers can use it regardless of platform. Since not all platforms guarantee to NULL out the return pointer on failure, we don't either, and require callers to check the return value for -1. The old Xprintf() API is deprecated, but left for compatibility for now. The new API is added in a new header so that it can be used in parts of the server such as hw/xfree86/parser that don't include all the server headers.

Just checking if numCrtcs (resp. numOutputs) is zero is thus not a good criteria to determine whetehr to use a realloc or a malloc. Since crtcs (resp. outputs) are NULL-initialized anyway, relying on numCrtcs (resp. numOutputs) is actually unnecessary, because reallocation of a NULL ptr is equivalent to a malloc anyway. Therefore, just use realloc() unconditionally, and ensure that the fields are properly initialized.

* add option keyconv=(auto|on|off)Ulrich Sibiller2017-11-235-0/+67
| | | | | | | | | | | | Adds a new option called "keyconv" to control keycode conversion. Before commit 2f2ade61a8823bad012737b2b388dcc168cccbbf keycode conversion was activated if the client was Linux and client side rules and/or model was "evdev". The only (and undocumented) way to disable that was providing a value different from "linux" for the "client" option (which had no other effect). The mentioned commit removed the dependency on Linux and so there was no way anymore to disable keycode conversion.
