Variables that are used by modules and are set inside 'if' blocks in the
nginx.conf file are not being set correctly. My nginx version (-V
output) is:
nginx version: nginx/0.7.64
built by gcc 4.3.3 (Ubuntu 4.3.3-5ubuntu4)
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --with-http_ssl_module
--add-module=../nginx_http_push_module-0.69
--add-module=../agentzh-echo-nginx-module-b8a0849
I'm setting $push_channel_id for the nginx_http_push_module using the
following if statement.
location ^~ /fjsub/ {
push_subscriber long-poll;
if ($arg_id) {
set $push_channel_id $arg_id;
}
}
The variable is set fine outside an 'if' statement but when the if
evaluates to true, the variable is not set.
I have duplicated this behaviour with the echo module as follows:
This will print "No":
location ^~ /echo/ {
set $myText "No";
if ($remote_addr ~* '000'){
set $myText "Yes";
}
echo $myText;
}
But when I replace '000' with '64' which matches my IP address, nginx
returns a 404 because the value of $myText is empty which means the echo
command didn't have any effect.
I have duplicated this behavior with only the echo module compiled in
and ssl and push removed.
I've already filed this as a bug on GIT for the NHPM (push) module but I
suspect this may be an nginx bug since it is broken across modules.
This bug also exists on the latest development build:
nginx version: nginx/0.8.28
built by gcc 4.3.3 (Ubuntu 4.3.3-5ubuntu4)
configure arguments: --prefix=/usr/local/nginx
--add-module=../agentzh-echo-nginx-module-b8a0849
What is surprising/confusing is that I'm setting variables inside
conditional statements that are used by proxy_pass and that works fine.
So does the upstream module (proxy_pass module) handle it's variables
differently to the echo and push modules?
Thanks,
Mark.
