* remove _X_DEPRECATED for XKeycodeToKeysymUlrich Sibiller2017-05-041-1/+4
| | | | | We need that function for performance reasons. By removing _X_DEPRECATED we get rid of compiler warnings.
* _XDefaultError: set XlibDisplayIOError flag before calling exitArthur Huillet2017-03-261-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | _XReply isn't reentrant, and it can lead to deadlocks when the default error handler is called: _XDefaultError calls exit(1). It is called indirectly by _XReply when a X protocol error comes in that isn't filtered/handled by an extension or the application. This means that if the application (or one of its loaded shared libraries such as the NVIDIA OpenGL driver) has registered any _fini destructor, _fini will get called while still on the call stack of _XReply. If the destructor interacts with the X server and calls _XReply, it will hit a deadlock, looping on the following in _XReply: ConditionWait(dpy, dpy->xcb->reply_notify); It is legal for an application to make Xlib calls during _fini, and that is useful for an OpenGL driver to avoid resource leaks on the X server side, for example in the dlopen/dlclose case. However, the driver can not readily tell whether its _fini is being called because Xlib called exit, or for another reason (dlclose), so it is hard to cleanly work around this issue in the driver. This change makes it so _XReply effectively becomes a no-op when called after _XDefaultError was called, as though an XIOError had happened. The dpy connection isn't broken at that point, but any call to _XReply is going to hang. This is a bit of a kludge, because the more correct solution would be to make _XReply reentrant, maybe by broadcasting the reply_notify condition before calling the default error handler. However, such a change would carry a grater risk of introducing regressions in Xlib. This change will drop some valid requests on the floor, but this should not matter, as it will only do so in the case where the application is dying: X will clean up after it once exit() is done running. There is the case of XSetCloseDownMode(RETAIN_PERMANENT), but an application using that and wishing to clean up resources in _fini would currently be hitting a deadlock, which is hardly a better situation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | XkbGetKeyboardByName relies on flags to read the data from the server. If the X server sends us the wrong flags or if a subreply is smaller than it should be, XkbGetKeyboardByName will not read all the available data and leave data in the buffer, which will cause the next _XReply() to fail with: [xcb] Extra reply data still left in queue [xcb] This is most likely caused by a broken X extension library [xcb] Aborting, sorry about that. xcb_io.c:576: _XReply: Assertion `!xcb_xlib_extra_reply_data_left' failed. Aborted Check if there is some extra data left at the end of XkbGetKeyboardByName() and discard that data if any is found.
