* Update currentTime in dispatch loopUlrich Sibiller2019-09-291-0/+3
| | | | | | | | | | | | | | | | | | commit 312910b4e34215aaa50fc0c6092684d5878dc32f Author: Chase Douglas <chase.douglas@canonical.com> Date: Wed Apr 18 11:15:40 2012 -0700 Update currentTime in dispatch loop A request, like input device grabs, may check a request timestamp against currentTime. It is possible for currentTime to lag a previously sent event timestamp. If the client makes a request based on such an event timestamp, the request may fail the validity check against currentTime unless we always update the time before processing the request.

This leads to weird behaviour for extensions that truly require running under the same OS services as the client, like MIT-SHM and DRI2. Add two new legal values for the initial connection's byteOrder field, 'r' and 'R'. These act like 'l' and 'B' respectively, but have the side effect of forcing the client to be treated as non-local. Forwarding proxies should attempt to munge the first packet of the connection accordingly; older servers will reject connections thusly munged, so the proxy should fall back to passthrough if the munged connection attempt fails.

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.

* Remove unneccesary casts from WriteToClient callsAlan Coopersmith2016-07-051-8/+8
| | | | | | | | | | | | | | Casting return to (void) was used to tell lint that you intended to ignore the return value, so it didn't warn you about it. Casting the third argument to (char *) was used as the most generic pointer type in the days before compilers supported C89 (void *) (except for a couple places it's used for byte-sized pointer math).

Many references to the WindowTable array already had the corresponding screen pointer handy, which meant they usually looked like "WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of keeping this information in a parallel array simplifies those expressions, and eliminates a MAXSCREENS-sized array. Since dix uses this data, a screen private entry isn't appropriate. xf86-video-dummy currently uses WindowTable, so it needs to be updated to reflect this change.

* Rename region macros to eliminate screen argumentMike Gabriel2016-05-021-6/+6
| | | | | | | | | | | | | | | | | | | | | This is a huge mechanical patch and a few small fixups required to finish the job. They were reviewed separately, but because the server does not build without both pieces, I've merged them together at this time. The mechanical changes were performed by running the included 'fix-region' script over the whole nx-X11/programs/Xserver tree: $ cd nx-X11/programs/Xserver && ( git ls-files | grep -v '^fix-' | xargs ./fix-region; ) And then, the white space errors in the resulting patch were fixed using the provided fix-patch-whitespace script. $ sh ./fix-patch-whitespace Thanks to Jamey Sharp for the mighty fine sed-generating sed script. v1: Keith Packard <keithp@keithp.com> (X.Org xserver commit: 2dc138922b7588515d5f2447e4b9dcdc0bef15e0) v2: Mike Gabriel <mike.gabriel@das-netzwerkteam.de> (apply fix-region script to nx-libs)
* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-281-3/+3
| | | | | | | | | | | | | | | | | | | | In the process of building nxagent against more and more system-wide installed X.org libraries, we come to the limit of including structs from this (bundled nx-X11) and that (system-wide X.Org) library. This commit introduces a clear namespace separation of headers provided by nx-X11 and headers provided by X.Org. This approach is only temporary as we want to drop all nx-X11 bundled libraries from nx-libs. However, for a while we need to make this separation clear and also ship some reduced fake X.Org headers that avoid pulling in libX* and libNX_X* symbols at the same time. This patch has been tested on Debian jessie and unstable and requires no overall testing on various distros and distro versions, as we finally will drop all libNX_X* libraries and build against X.org's client libs. For now, this hack eases our development / cleanup process.
