* nxagent: remove now-obsolete own copies of ScreenSaver procsUlrich Sibiller2020-04-071-149/+0
| | | | | we moved the auto-disconnect feature to an own timer so there's no need for a special treatment in screen saver stuff anymore.
* nxagent: re-implement timeout handlingUlrich Sibiller2020-04-071-6/+6
| | | | | | Option -timeout used the screensaver facility. This patch changes that to an own timer that is independent. This effectly means we can drop most of the derived screensaving stuff in a follow-up commit.
* nxagent: remove another xprint renmantUlrich Sibiller2020-01-061-2/+12
| | | | | | reqeuestingClient was dropped with the XPRINT drop. Unfortunetely we are usign it in Image.c. So let's introduce nxagentRequestingClient as replacement for now.

* Revert "nxagent: rework Bool handling"Ulrich Sibiller2019-02-151-3/+3
| | | | | | | | | | | | This reverts commit 16cd2bbe1c4425e3fa557f9ca0723aa94a50b071. It turned out that I had missed some of the Booleans being actually tristate variables. I think I can fix this (they do not need to be tristate) but I revert this for now to get back to a working state (there are reports about non-working fullscreen mode and reconnect problems).

However, the Popen code tears down and recreates the SIGALRM handler via OsSignal(), and this flag is dropped at this time. Clean the code to use just a single codepath for creating this signal handler, always applying SA_RESTART.

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%.
