Which OS? Which version of CVSweb? Can you post of a diff between cvsweb.conf.dist and your cvsweb.conf? Uncommenting '$DEBUG = 1;' in cvsweb.conf will cause STDERR to be sent to your web server error log instead of /dev/null. However, for the rcsdiff command STDERR is sent to STDOUT by default so you are already seeing any errors in your web browser. Attached is a patch for CVSweb 3.0.6 which will print out the rcsdiff command used. It should print out at the top of the diff output. One final note: When testing from the command-line be sure to run the command as the web server user (i.e., 'sudo -u www rcsdiff ...'). -Jonathan --------------000408030105050702090708 Content-Type: text/plain; name="print_command.patch" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="print_command.patch" --- cvsweb.cgi.old Wed Jan 11 22:12:42 2006 +++ cvsweb.cgi Wed Jan 11 22:16:09 2006 @@ -2336,6 +2336,8 @@ if (!open($fh, "-|")) { # child open(STDERR, ">&STDOUT"); # Redirect stderr to stdout openOutputFilter(); + print(join(' ', $CMD{rcsdiff}, @rcsdiff_options, @difftype, "-r$rev1", + "-r$rev2", $fullname, "\n")); exec($CMD{rcsdiff}, @rcsdiff_options, @difftype, "-r$rev1", "-r$rev2", $fullname) or exit -1; } --------------000408030105050702090708--
