I have a question about this last line of the patch. Are GITWEB_JS and 
GITWEB_CSS supposed to be a source path or a URI?

The documentation for install (and my previous assumption) was that they 
represented the path on the target web server. I'm used to overriding 
them so that gitweb.cgi can live in my /cgi-bin directory, but the 
static files are served from /gitweb which is readable but not executable.

After this patch I had to removed $(GITWEB_JS) and $(GITWEB_CSS) from 
the list of dependencies for gitweb.cgi otherwise make failed.

Have I got the wrong end of the stick?

Thanks a lot for noticing this bug.


GITWEB_JS and GITWEB_CSS were originally meant to be URI to file with
gitweb JavaScript code and default gitweb stylesheet,... but during work
on minification of JavaScript code and CSS file it somehow got confused
to mean source path.

If I remember correctly the original patch, before adding required
support for minified gitweb.js and gitweb.css to git-instaweb script,
and before support for CSS minification had

   ifdef JSMIN
   gitweb.cgi: gitweb.perl gitweb.min.js
   else
   gitweb.cgi: gitweb.perl
   endif

which should probably be replaced in current situation by

   ifdef JSMIN
   gitweb.cgi : gitweb.min.js
   endif
   ifdef CSSMIN
   gitweb.cgi : gitweb.min.css
   endif

just adding prerequisites to gitweb.css target in gitweb/Makefile


I guess that support for adding minifiction support to git-instaweb
would need to be more complicated.  Perhaps

  $(notdir $(GITWEB_JS))   # Makefile function

or

  $(basename $GITWEB_JS)   # shell command

But I guess that it wouldn't work for all cases...
