From 81d3fe9f4871e42ebd1af0221fa091fe5476e2f7 Mon Sep 17 00:00:00 2001 From: Giuseppe Bilotta Date: Sun, 15 Feb 2009 10:18:36 +0100 Subject: [PATCH] gitweb: fix wrong base URL when non-root DirectoryIndex CGI::url() has some issues when rebuilding the script URL if the script is a DirectoryIndex. One of these issue is the inability to strip PATH_INFO, which is why we had to do it ourselves. Another issue is that the resulting URL cannot be used for the tag: it works if we're the DirectoryIndex at the root level, but not otherwise. We fix this by building the proper base URL ourselves, and improve the comment about the need to strip PATH_INFO manually while we're at it. Additionally t/t9500-gitweb-standalone-no-errors.sh had to be modified to set SCRIPT_NAME variable (CGI standard states that it MUST be set, and now gitweb uses it if PATH_INFO is not empty, as is the case for some of tests in t9500).
