Incorrect PATH_INFO when FastCGI is serving "/"

Description

When mod_fastcgi is serving "/" i.e. configured as following


fastcgi.server = (
   "/" => (
      ...
   )
)

it produces wrong SCRIPT_NAME and PATH_INFO.

For example, request for /test/url is represented as


SCRIPT_NAME = "/test" 
PATH_INFO = "/url"

while it has to be


SCRIPT_NAME = "" 
PATH_INFO = "/test/url"

Interesting that mod_scgi doesn't have that issue.

One slightly hacky fix for mod_fastcgi, needs porting to mod_scgi (and more testing!)

This occurs when mapping any URL ending in "/" to FastCGI. The same mapping with the ending "/" removed works correctly.

This causes problems for trac, when it is sitting in the root directory. See trac bug 2418.

Any idea why this has not been checked in? It doesn't look hackish, given we also port it to all places using the same code.

FWIW, the above patch fixes this bug for mod_scgi as well (in my case, tested with DrProject).

I've been hit by the same problem when trying to use Moin as the root URI.

There is no straightforward solution to this, as there is no generic pattern for splitting the URI in SCRIPT_NAME and PATH_INFO. In some cases you want the whole URI in PATH_INFO, in some other cases you want SCRIPT_NAME to be set, and you could imagine thousands of other cases.

I'd like this to be fixed by a URI => PATH_INFO mapping, with a new configuration variable. The result could look like this:

fastcgi.path_info = (
"^/(admin|stats)/(.*)" => ("/$1", "/$2"),
"^(.*)$" => ("", "$1"),
)

This way /admin/foo would lead to SCRIPT_NAME="/admin" and PATH_INFO="/foo", while /bar would lead to SCRIPT_NAME="" and PATH_INFO="/bar".
