Bug 15363

This doesn't seem to work with either current or update candidate.

When visited at http://localhost/cgi-bin/mapserv? it gives a server error..

Error message:
End of script output before headers: mapserv

Apache error_log shows..

[cgi:error] [pid 1748] [client 127.0.0.1:36707] AH01215: /var/www/cgi-bin/mapserv: error: `/var/www/cgi-bin/.libs/mapserv' does not exist
[cgi:error] [pid 1748] [client 127.0.0.1:36707] AH01215: This script is just a wrapper for mapserv.
[cgi:error] [pid 1748] [client 127.0.0.1:36707] AH01215: See the libtool documentation for more information.
[cgi:error] [pid 1748] [client 127.0.0.1:36707] End of script output before headers: mapserv


The /var/www/cgi-bin/.libs directory is not there. cgi-bin/mapserv is a bash script.

#! /bin/sh

# mapserv - temporary wrapper script for .libs/mapserv
# Generated by libtool (GNU libtool) 2.4.2
#
# The mapserv program cannot be directly executed until all the libtool
# libraries that it depends on are installed.
#
# This wrapper script should never be moved out of the build directory.
# If it is, it will not operate correctly.


is it possible the wrong file has been used here?

# cd /var/www/cgi-bin/

# ./mapserv 
./mapserv: error: `/var/www/cgi-bin/.libs/mapserv' does not exist
This script is just a wrapper for mapserv.
See the libtool documentation for more information.

A simple test is to try and run it:

$ ./mapserv
This script can only be used to decode form results and
should be initiated as a CGI process via a httpd server.

Indeed, quite bogus.  All of those things that are in /var/www/cgi-bin are supposed to the binaries in /usr/bin, but looking at the Makefile, it looks like the only one that's actually needed in cgi-bin is mapserv itself.  It appears that this was broken in the update to 6.0.1 on 2011-09-16 :D.

I just pushed mapserver-6.2.2-1.1.mga4 which should fix this.

Now getting..

Symbolic link not allowed or link target not accessible: /var/www/cgi-bin/mapserv

It's a dangling link. It's missing some ..'s.

# ll /var/www/cgi-bin/
total 2280
lrwxrwxrwx 1 root root      22 Mar  6 13:09 mapserv -> ../..//usr/bin/mapserv

# which mapserv
/usr/bin/mapserv

# cd /var/www/cgi-bin/
# rm mapserv
rm: remove symbolic link âmapservâ? y
# ln -s ../../../usr/bin/mapserv mapserv
# ll
total 2280
lrwxrwxrwx 1 root root      24 Mar  6 13:15 mapserv -> ../../../usr/bin/mapserv*

Even then though, after restarting httpd, it's still giving 403 forbidden.
Symbolic link not allowed or link target not accessible: /var/www/cgi-bin/mapserv

# rm mapserv 
rm: remove symbolic link âmapservâ? y
# cp /usr/bin/mapserv .
# systemctl restart httpd.service

Then it works. Browsing to http://localhost/cgi-bin/mapserv shows..
"No query information to decode. QUERY_STRING is set, but empty. "

So links are not followed.

Thanks Claire.  I changed it to copy the executable instead of symlinking it.

mapserver-6.2.2-1.2.mga4

Note that you won't be able to upgrade to it from 1.1.mga4 if the symlink is in place, but upgrading from the previous versions will work fine.

Whiteboard: has_procedure feedback => has_procedure

Actually symlinking should ve ok, but you due to apache lockdown, you need something like:

<Directory /path/to/dir>
    Options +FollowSymLinks
    Require all granted
</Directory>

CC: (none) => tmb

That may be not a good idea with cgi-bin though Thomas

It had also slipped my mind that changing it to a symlink from a regular file (in the core/release version) would have caused errors on upgrading, so it's actually fortunate that it didn't work :o)

It didn't appear to cause any error. I'll retest the new one when it lands anyway.
