From 24d4afcdc79cb250131841040b803401d261a473 Mon Sep 17 00:00:00 2001 From: John 'Warthog9' Hawley Date: Sat, 30 Jan 2010 23:30:41 +0100 Subject: [PATCH] gitweb: Check that $site_header etc. are defined before using them If one of $site_header, $site_footer or $home_text is not defined, you get extraneous errors in the web logs, for example (line wrapped for better readibility): [Wed Jan 13 16:55:42 2010] [error] [client ::1] [Wed Jan 13 16:55:42 2010] gitweb.cgi: Use of uninitialized value $site_header in -f at /var/www/gitweb/gitweb.cgi line 3287., referer: http://git/gitweb.cgi This ensures that those variables are defined before trying to use it. Note that such error can happen only because of an error in gitweb config file; building gitweb.cgi can make mentioned variables holding empty string (it is even the default), but they are still defined.
