Description: Logical error in fopen-wrappers.c
Thanks for the response, however, can you confirm that there is a logical coding error
here?
The DOCUMENT_ROOT patch is secondary and would be nice - but is the bug going to be
fixed in 4.0.5 ?
Regards,
Paul.

This will not make it into 4.0.5 as this was branched a while back but it might well
make it into 4.0.6. Ill get a developer to look at this patch.

I thought, while I'm here, I'd submit a patch to fix this.
The patch also includes support for an additional special case in php.ini's
open_basedir.
The current "." allows scripts to access files in the same directory as the script.
"DOCUMENT_ROOT" allows a script to access any other file in the virtualhost's
directory tree. DOCUMENT_ROOT is calculated by PATH_TRANSLATED and removing
SCRIPT_URI from the end - This conveniently works for both full Apache Virtalhosts and
mod_aliased Mass virtual hosting (I don't know if this is true for the newer mod_vhost
- just check what PATH_TRANSLATED and SCRIPT_URI is set to in phpinfo() - if removing
the latter from the former is the sites docroot then you are away).
Anyway, the patch: code shamelessly copied from the "." segment :)
