Re: mod_fcgid: different instances of the same program
On Mon, Nov 9, 2009 at 5:16 PM, Danny Sadinoff danny.sadin...@gmail.com wrote: 2) Virtual hosts The above item holds true even across virtual hosts. So while it's possible to adjust the FcgidInitialEnv items on a per-vhost basis, this is a recipe for disaster if two vhosts point at the same fcgi executable, because the resulting processes with potentially different Environments will be inserted into the same pool. Once that occurs, we may expect that a server spawned with config defined in vhost A will be parcelled out to vhost B. The first time that i use mod_fcgid, i probe SetEnv instead FcgidInitialEnv because i not readed complete the documentation, but SetEnv and FcgidInitialEnv causes the same effect, the difference is where you put the SetEnv. The FastCGI especification only needs the environment variables that uses (FCGI_SOCKET, FCGI_USER, ALLOWED_ENV, etc.) you could use SetEnv if need more flexibility than FcgidInitialEnv. -- Felipe Alcacibar Buccioni
Re: mod_rewrite and mod_fcgid pass wrong fcgi request

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

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.
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

Re: mod_rewrite and mod_fcgid pass wrong fcgi request
... 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. 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??...

Re: mod_rewrite and mod_fcgid pass wrong fcgi request
