* Render.c: Improve situation for multiple trapezoid requests.Oleksandr Shneyder2017-07-311-14/+1
| | | | | | | | | | | | | | | | | | | This change improves the situation in nxagent for the following issue: ``` "XRenderCompositeTrapezoids builds RenderTrapezoids requests to composite the specified list of trapezoids to dst. XRenderCompositeTrapezoids will split the list of trapezoids to build requests no larger than the maximum request size supported by the server. This can create rendering artifacts as the precompositing done by RenderTrapezoids when a maskFormat is specified cannot span multiple requests." ``` For more information see: https://lists.freedesktop.org/archives/xorg/2008-June/036124.html Fixes ArcticaProject/nx-libs#336.
* treat options parameter as option string if it starts with nx/nxUlrich Sibiller2017-07-251-1/+16
| | | | | | | | | | This way one can easily pass options to nxagent run as Xnest replacement without having to create a temporary options file. Please note that it is not of much use for normal sessions. Options passed like this cannot be changed after startup so a reconnect may not work as expected. Fixes ArcticaProject/nx-libs#476

* hw/nxagent/Window.c: Introduce NX_REAL_WINDOW window property.Mike Gabriel2017-06-304-0/+45
| | | | | | | | | | | | | | | | In nxagent sessions, all X11 clients have a representation of their NX session-side window object on the real X-Server side. The window object gets stored in the new NX_REAL_WINDOW window property immediately after window creation. This mapping is created in nxagentCreateWindow(). On session resumption, the client side window IDs normally change. Thus, during session resumption, all NX_REAL_WINDOW properties require being updated. This happens in nxagentReconnectWindow(). While a session is suspended, the NX_REAL_WINDOW property does not exist. It gets removed during nxagentDisconnectWindow().

These hangs are not happening in 3.5.0 releases if the nx-libs. The commit above is responsible for them so we take that back. Interestingly nxcomp has special treatment for XGetKeyboardMapping() so it should normally speed up things but it results in the opposite for us. Needs further examination. This fixes ArcticaProject/nx-libs#450

This patch is still a candidate for being re-implemented without extending the _PictSolidFill struct, but for now, we'll have to re-introduce commit db8705 for the sake of having fonts readable after resumption of remote NX sessions.

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 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.
