Description Frederic Crozat 2003-02-06 01:34:31 UTC

Fontconfig crashes if HOME variable is not set (it can
be the case when using usermode to get root access)..

The attached patch fixes this problem and only relies on $HOME
variable presence when getpwuid doesn't give any info (this is the glib2 way..)

I would prefer to use $HOME and fall back to getpwuid only if that's not set, or
perhaps if the application is setuid.  getpwuid seems a bit expensive to use in
every application.

I don't have any strong feelings for any approaches.. Since I didn't knew which
one was better, I choose the glib2 way

Comment 4 Keith Packard 2003-02-06 11:30:52 UTC

I've made a minimal patch that solves the immediate problem.
