X will scan for an available display number and write that number back to the launching process, at the same time as SIGUSR1 generation. This means display managers don't need to guess at available display numbers. As a consequence, if X fails to start when using -displayfd, it's not because the display was in use, so there's no point in retrying the X launch on a higher display number.

If we inherited a signal mask from the parent process that ignores SIGUSR1, then we will send SIGUSR1 to the parent to indicate when we're ready to accept connections. Unfortunately, we send this notification way too early, right after creating the sockets rather than just before entering the main loop.

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.

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%.

This commit makes it complete by removing client->lastDrawable/lastGC everywhere thus fixing ArcticaProject/nx-libs#306 and #322 commit e6f2f6427122dc4bc802acebf26f8cec16cd2f62 Author: Mike Gabriel <mike.gabriel@das-netzwerkteam.de> Date: Mon Jun 20 16:45:38 2016 +0200 dix: remove caching of drawables and graphics contexts.

Quote Alan Coopersmith: "The consumer was in past versions of the headers now located in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h, all the event definitions were only available if NEED_EVENTS were defined, and all the reply definitions required NEED_REPLIES. Looks like Xproto.h dropped them by X11R6.3, which didn't have the #ifdef's anymore, so these are truly ancient now."

* Remove unneccesary casts from WriteToClient callsAlan Coopersmith2016-07-055-58/+58
| | | | | | | | | | | | | | 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).

* Make WriteEventsToClient/WriteToClient no-op on fake or dead clients.Jamey Sharp2016-07-051-0/+3
| | | | | | | | | | | | | | | | | | This matches the test in TryClientEvents, and is a superset of tests done by the callers of these functions. The consequence of forgetting these tests is a server crash, so they're always desirable. In my opinion, it's better to not require the callers to remember to do these checks. For callers that don't do very much work before calling WriteToClient or WriteEventsToClient, I've removed the redundant checks.
