Error Recovery Support In The Wayland Client

David Herrmann has posted patches for implementing error recovery within the Wayland client library.

Herrmann, the developer that's been aspiring towards killing the kernel console (CONFIG_VT) by providing KMSCON, FBLOG, and a native Wayland terminal emulator, took a stab at error recovery for libwayland-client.

He writes in his mailing list message, "This patchset is some _untested_ (but compile-tested) proposal to add error-recovery paths to libwayland-client. The basic idea is to set a global flag when a fatal-error occurs and waking up all event-queues. All sleeping dispatchers and all further dispatches will return -1 and errno set to the fatal error code."

This work consists of 12 patches for error handling/recovery amd some small changes still need to be done for initiating a graceful shutdown should a Wayland error arise. With the Wayland 1.0 release happening in a few days, this error support might not make the cut for this next release so it would then be postponed to the next stable Wayland update.
