Description Jan Beich freebsd_committer 2017-12-10 19:02:46 UTC
Created attachment 188691 [details]

Instead of disabling posix_fallocate() for all FreeBSD versions let's treat failure gracefully, similar to base r325420.

Can someone help with testing? I don't use Wayland.
Comment 1 Greg V 2017-12-10 20:32:54 UTC
This is the same os-compatibility.c file as in Weston. I would prefer using SHM_ANON instead of tempfiles (and posix_fallocate doesn't work on that).

Comment 2 Niclas Zeising freebsd_committer 2018-01-12 21:48:32 UTC

Greg, any chance you can check with upstream about including your changes?

I don't have a wayland/weston system myself to test with currently.
Comment 3 Greg V 2018-01-13 19:37:34 UTC
(In reply to Niclas Zeising from comment #2)
I've sent this change as a patch to weston (not to libwayland yet) but it was not reviewed yet.
Comment 4 Niclas Zeising freebsd_committer 2019-07-07 16:19:28 UTC
I've added a similar patch that uses SHM_ANON instead of posix_fallocate.  It can be found here, together with the update to wayland 1.17.
