adding environment variables from module

[Nicolae Mihalache <ma...@abcpages.com>]

Hi!

First of all, this is my first attempt to modify an Apache module.
I'm tring to modify mod_mysql_auth to set some environment variables 
that  will be used by the CGI scripts and also by the mod_autoindex 
(wich I will also modify)  to change the output based on the priviledge 
of the authenticated user.
my modification goes into mysql_check_auth and is basically:
table *e = r->subprocess_env;
ap_table_setn(e,"SA_PRIV",ap_pstrdup(r->pool, data[0]));
where data[0] is previously obtained from database.

The problem is that "SA_PRIV" environment variable does not show up in 
the cgi script. I tried printing all the variables after setting them 
and it seems that at that stage the only variables that exists in that 
table are mine and UNIQUE_ID. UNIQUE_ID is shown in the cgi script.
Please tell me what I'm doing wrong, isn't r->subprocess_env the correct 
table to add environment variables?
Are these things documented somwere?

Thank you,
Nicolae

If you are running suexec, then the environment is cleaned using a
compile-time "safe list".

I did that, and the variables show up in printenv directive. Very 
strange, my
cgi is as simple as that:

#!/bin/sh
echo "Content-Type: text/plain"
echo
echo
env

Any ideea why this one does not show the variables? Is mod_cgi 
restrictive about the variables it exports to cgi scripts?

Thank you,
Nicolae
