Subject: Bug 620496 - schema compiler: reject invalid paths
X-Git-Tag: 2.25.8~15
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=71c5e3f899bf15c9dee09b36f146c5e72652d72b;p=platform%2Fupstream%2Fglib.git

Bug 620496 - schema compiler: reject invalid paths

The GSettings schema compiler was accepting any string as a path.  It is
probably quite a common mistake to suspect that '/apps/foo' is a valid
path name when this will cause all sorts of trouble later.  Check for
this case and report the error.
