Things that killed my motivation to play with wayland

[darxus at chaosreigns.com]

All three of these bugs have been fixed.  That's pretty awesome.

I have my automated build tests running again, including a cairo make
test, and have used weston some.  I hit another weston crash, and then
accidentally overwrote the output I had while trying (and failing)
to reproduce it, so I had nothing to report.  I'll keep trying to use it.

The screensaver related hanging I was seeing can be worked around easily by
launching weston with weston-launch -- -i0
(to disable the screensaver)
( https://bugs.freedesktop.org/show_bug.cgi?id=65802 )

The gobject-introspection make test failure I caught several days ago has
been fixed:  https://bugzilla.gnome.org/show_bug.cgi?id=702505

These things are currently failing make check / test:
gtk+ https://bugzilla.gnome.org/show_bug.cgi?id=702704
libunwind https://savannah.nongnu.org/bugs/index.php?39294
weston https://bugs.freedesktop.org/show_bug.cgi?id=61296


I just uploaded current versions of my buildtest script and its config
file, for 45 repos:  http://www.chaosreigns.com/code/buildtest/

Directions for getting a cairo make test to pass:

Interestingly, if I use my script to build only the ~25 repos cairo depends
on, that gives me different reference images than when I do my full set of
~45 repos.  Almost certainly because cairo is somehow generating different
test result images because of having a newer version of some dependency.
Which seems likely to be bad.
