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 documentation about the need to strip PATH_INFO manually while we're at it. --- gitweb/gitweb.perl | 16 ++++++++++++---- 1 files changed, 12 insertions(+), 4 deletions(-) diff --git a/gitweb/gitweb.perl b/gitweb/gitweb.perl index c2c8080..48cfd5f 100755 --- a/gitweb/gitweb.perl +++ b/gitweb/gitweb.perl @@ -27,15 +27,23 @@ our $version = "++GIT_VERSION++"; our $my_url = $cgi->url(); our $my_uri = $cgi->url(-absolute => 1); -# if we're called with PATH_INFO, we have to strip that -# from the URL to find our real URL -# we make $path_info global because it's also used later on +# When the script is used as DirectoryIndex, the URL does not contain the name +# of the script file itself, and $cgi->url() fails to strip PATH_INFO, so we +# have to do it ourselves.
