[Patch] Also quit(wl) on EOF for wl.sock[0] (938 bytes, text/plain)

Description Bruno 2015-03-01 22:45:52 UTC 
Created attachment 113903 [details]
[Patch] Also quit(wl) on EOF for wl.sock[0]

When sending SIGTERM to weston-launch to terminate session, or even when weston fails to start (e.g. no GLESv2 support), weston-launch ends up in tight poll() & recvmsg() loop where poll() returns POLLIN|POLLHUP for wl.sock[0].

This issue seems to only happen when stracing weston-launch.

Hi,

a patch, cool! Could you post it to the mailing list, please?
That way we get it tracked in http://patchwork.freedesktop.org/project/wayland/list/ and into the review pipe.
