mod_rewrite and mod_fcgid pass wrong fcgi request

Hi, i was friyng my brain the whole day trying to use a mod_rewrite
simple rewrite to a php pathinfo running via mod_fcgid.

http://domain.tld/path/info/use -> http://domain.tld/index.php/path/info/use

i trying so much posibilities, but when i take a strace to a php-fcgi
application i found the surprise that php treats to open the file

redirect:/index.php/path/info/use

i cannot know if this behavior is a problem in mod_rewrite or mod_fcgid.
someone can guide me with this?

Re: mod_rewrite and mod_fcgid pass wrong fcgi request [In reply to]

i was commented that in the wrong list? i saw this list in the
mod_fcgid's page and for that reason i posted that here, but i don't
know if this is a bug or feature or anyelse, or what is the module
that may be wrong. someone can tell me if i wrong please?

this is a nice list for the comments that i readed, congrats!

cheers!

in the long term users [at] http is a better list for likely configuration
issues like this; we've been pointing mod_fcgid to this dev@ list
because mod_fcgid is new to this community and perhaps very few people
have used it

I don't know what your rewrite config is, but rewrite isn't required
to use path info. Can you post a minimal config that illustrates the
problem?

Something to consider when debugging mod_fcgid issues is that the same
config should work with mod_cgi[d] simply by changing the handler from
fcgid-script to cgi-script. More people on the users@ mailing list
are able to help with mod_cgi config issues.

i using a 307 redirect temporally, but that is the configuration that

i take your advice and now i probe it, thanks :)

i take the dessicion to use mod_fcgid because i use mapserver php
module, and this module does not have a good memory management, and
with mod_fcgid i solve this problems very efficiently.

This is apparently PR 40781:

https://issues.apache.org/bugzilla/show_bug.cgi?id=40781

I see that one or two people have suggested work-arounds in that PR,
but they don't seem to apply directly to your configuration. Perhaps
some mod_rewrite experts on the user list can help solve this, with
some adjustment to your mod_rewrite configuration so that in effect
PATH_TRANSLATED doesn't get left with "redirect:"?

FWIW, changing the FcgidWrapper directive temporarily to point to this
Perl script is helpful for seeing what mod_fcgid is telling PHP:

#!/usr/bin/perl

use strict;
use CGI::Fast;

while (my $q = CGI::Fast->new) {
print "Content-Type: text/plain\r\n\r\n";

foreach my $env (keys %ENV) {
print "env $env = $ENV{$env}\n";
}
}

(though possibly you don't have CGI::Fast or its FCGI dependency installed)

I wasn't very clear with this suggestion ;) My thought was to see
what it takes to get it working with CGI first, as more people could
potentially help with a CGI issue. Once it works with CGI, it should
be straightforward to convert the config to FastCGI. Also, if the
config then doesn't work after converting to FastCGI then it is more
likely a mod_fcgid bug.

Effectively, that happens to me, but not in cgi mode (cgid) or with
php's libphp5 (apxs module) it happens only with mod_fcgid.

for no errors i take the straces dumps from php-cgi with mod_cgid and
mod_fcgid, to know better what it's happens here is the vars that
passes to me.

at least is a bug, that is great to clear me that dude.

but i habe a last dude. The way of the good Open Source Software user
is to report the bug, but where is the bug, in the mod_fcgid or in the
mod_rewrite??

lot of thanks Jeff

When comparing modes of PHP execution:

- CGI and FastCGI are directly comparable because the information that
Apache needs to pass to PHP is the same. (In fact, mod_cgi[d] and
mod_fcgid use the same core Apache code to build almost all of that
information.)

You should be able to take your CGI configuration and change the
handler from cgi-script to fcgid-script and have PHP work as FastCGI.
One nuance is that if you're relying on ScriptAlias you'll need to use
both Alias and Options +ExecCGI in the FastCGI equivalent.

- mod_php and mod_fcgid configurations are not comparable.

I believe that the bug is in mod_rewrite, and is already tracked by

As you sayed it i made a similar environment (the difference is the
FcgidWrapper line) from mod_cgid to mod_fcgid and the result is the
same, in the mod_cgid environment all runs good and in the mod_fcgid
persisst the problem...

rohan counter # cat /etc/apache2/modules.d/70_php5_cgi.conf
<IfDefine PHP5CGI>
ScriptAlias /.httpd/cgi-interpreters /var/cgi-interpreters/
<Directory "/var/cgi-interpreters">
AllowOverride None
Options None
Options +ExecCGI

Order allow,deny
Allow from all
</Directory>

<IfDefine FCGID>
FcgidWrapper "/var/cgi-interpreters/php-cgi" .php
FcgidWrapper "/var/cgi-interpreters/php-cgi" .php2
FcgidWrapper "/var/cgi-interpreters/php-cgi" .php3
FcgidWrapper "/var/cgi-interpreters/php-cgi" .php4
FcgidWrapper "/var/cgi-interpreters/php-cgi" .php5
FcgidWrapper "/var/cgi-interpreters/php-cgi" .phtml

FcgidInitialEnv PHP_FCGI_CHILDREN "12"
FcgidInitialEnv PHP_FCGI_MAX_REQUESTS "1"

AddHandler fcgid-script .php .php3 .php4 .php5 .php6 .phtml
</IfDefine>

<IfDefine !FCGID>
AddHandler php-script .php .php3 .php4 .php5 .php6 .phtml
Action php-script "/.httpd/cgi-interpreters/php-cgi"
</IfDefine>

<FilesMatch \.ph(p[2-6]?|tml)$ >
Options +ExecCGI
</FilesMatch>

DirectoryIndex index.php index.php3 index.php4 index.php5 index.phtml
</IfDefine>

Any suggestion or step to do??...

Thanks Jeff

PHP can be configured via Action instead of FcgidWrapper with
mod_fcgid too. That is the most direct comparison.

BTW, check the mod_fcgid docs for comments on these two PHP
environment variables.

Use Action with mod_fcgid too so that mod_fcgid processing works
through the same mechanisms as with your mod_cgid setup.

I'll try to find some time today to play with that as well.
Eventually I'd like the documentation to show an Action-based example,
with support for easily switching between CGI and FastCGI for
debugging or other purposes.

Here is your CGI configuration, munged a bit to work in my setup.
Also, I changed your ScriptAlias to a regular Alias + "SetHandler
cgi-script". That yields a configuration that maps directly to
mod_fcgid.

With this config, I can use either the "SetHandler cgi-script" or the
"SetHandler fcgid-script" to select CGI or FastCGI, and I don't see
the redirect: problem with path info.

Alias /interpreters/ /Users/trawick/inst/5211/bin/

<Directory /Users/trawick/inst/5211/bin/>
# SetHandler cgi-script
SetHandler fcgid-script
AllowOverride None
Options None
Options +ExecCGI
Order allow,deny
Allow from all
</Directory>

AddHandler php-script .php
Action php-script "/interpreters/php-cgi"
<FilesMatch \.php$>
Options +ExecCGI
</FilesMatch>
DirectoryIndex index.php

HTH!
