* nxagent: implement RPATH/RUNPATH override for libX11.Mihai Moldovan2017-12-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed in ArcticaProject/nx-libs#610, we need a way to load libNX_X11 as a fake version of libX11 into nxagent's address space. For doing so, we have to link against libX11 at build-time and specify a(n) RPATH/RUNPATH to our libX11 -> libNX_X11 compat symlinks. This commit is essentially doing a cross between options 3 and 4 discussed in the provided GH issue. We link libX11 early (before specifying -Lcompat_symlinks_dir), so that the linker finds the "real" libX11 version with the libX11 SONAME. This leads to our binary depending upon both libX11 and libNX_X11 SONAMEs. We already always added RPATH/RUNPATH, but these values are not passed down to dependent libraries. What happens at run-time is that the loader searches for a libX11 SONAME, takes RPATH/RUNPATH into account and loads our libNX_X11 library instead via the compat symlinks. This satisfies the libX11 SONAME and dependent libraries will *not* load the system libX11 version again. Debian's dpkg-shlibdeps isn't quite happy about this mismatching SONAME situation, so instruct to look the other way while we're minding our business. Fixes: ArcticaProject/nx-libs#610
* Support building with legacy (pre-7.1.0) Xext proto versions.Mihai Moldovan2017-12-161-1/+10

* Regression fix for added libXfont2 API support:Mike Gabriel2017-04-101-1/+10
| | | | | | | | | | - Move FONT_DEFINES and XLIBFONT definition to from Server.tmpl to Imake.tmpl. - Add FONT_DEFINES to ALLDEFINES. - Drop SpecialCObjectRules with FONT_DEFINES from various Imakefiles again, FONT_DEFINES is now set "globally". - Hand over FONT_DEFINES from main Makefile to nx-X11's make BuildEnv to make gccmakedep happy.
* Xserver: Support building against libXfont2 (v2) API and old libXfont(1) API ↵Mike Gabriel2017-04-101-0/+3

If process execution is inside certain blocking system calls when these signals arrive, e.g. with the kernel blocked on a contended semaphore, the system calls will be interrupted. Some system calls are automatically restartable (the kernel re-executes them with the same parameters once the signal handler returns) but only if the signal handler allows it. Set SA_RESTART on the signal handlers to enable this convenient behaviour.

Rather than doing this, just stop the timer before going into the select() portion of the WaitFor loop. It's a cheap system call, and it will only get called if there's no more commands batched up from the active fd. This change also allows some of the functions to be simplified; setitimer() will only fail if it's passed invalid data, and we don't do that... so make it void and remove all the conditional code that deals with failure. The change also allows us to remove a few variables that were used for housekeeping between the signal handler and the main loop. Signed-off-by: Keith Packard <keithp@koto.keithp.com> **Note**: The above change also required ABI changes in hw/nxagent/. commit abe0a51f3f790f8c055289465e130177c4b647cc Author: Ben Byer <bbyer@bbyer.apple.com> Date: Fri Sep 21 17:07:36 2007 -0700 So, like, checking return codes of system calls (signal, etc) is good.

Because our "popen" implementation uses stdio, and because nobody's stdio library is capable of surviving signals, we need to make absolutely sure that we hide the SIGALRM from the smart scheduler. Otherwise, when you open a menu in openoffice, and it recompiles XKB to deal with the accelerators, and you popen xkbcomp because we suck, then the scheduler will tell you you're taking forever doing something stupid, and the wait() code will get confused, and input will hang and your CPU usage slams to 100%.
