[Bug 54973] New: mod_proxy_fcgi does not honnor Timeout /
ProxyTimeout
https://issues.apache.org/bugzilla/show_bug.cgi?id=54973
Bug ID: 54973
Summary: mod_proxy_fcgi does not honnor Timeout / ProxyTimeout
Product: Apache httpd-2
Version: 2.4.4
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_proxy_fcgi
Assignee: bugs@httpd.apache.org
Reporter: bruno.canet@b-source.ch
Classification: Unclassified
mod_proxy_fcgi is configured to proxy request to php-fpm as follow:
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/opt/httpd/htdocs/app/$1
If a php script takes more than 30 seconds to execute, a HTTP RC 500 is
returned to the client.
php max_execution_time is set to 300 seconds
I used the following script to validate that the error was not due to php
max_execution_time issue.
<?php
error_log("executing script... ");
$time = time();
for ($t = 0; $t <= 15; $t++) {
error_log("Logging: $t (".(time()-$time)." seconds)");
sleep(5);
}
error_log("execution done (".(time()-$time)." seconds)");
?>
after 30 seconds, the HTTP 500 is returned to the client, but in the php
error_log the script continue its execution.
According to the documentation, TimeOut is set to 60 seconds by default, so it
should not be an issue, but in case, the following explicit definition were
tested without improvement:
1. ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/opt/httpd/htdocs/app/$1
timeout=300
2. in virtual host: ProxyTimeout 300
3 in server config: TimeOut 300
The only workaround found was to hardcode the timeout in the mod_proxy_fcgi.c:
--- ./modules/proxy/mod_proxy_fcgi.c.orig 2013-04-16 16:09:25.970332062
+0200
+++ ./modules/proxy/mod_proxy_fcgi.c 2013-04-16 16:09:56.311088966 +0200

/* We need SOME kind of timeout here, or virtually anything will

if (! conn->worker->s->timeout_set) {
- timeout = apr_time_from_sec(30);
+ timeout = apr_time_from_sec(300);
}
rv = apr_poll(&pfd, 1, &n, timeout);

The fact that you were not able to set "timeout=300" is caused by PR 43513.

we confirm this behavior with:
mod_proxy_fcgi
mod_proxy
apache event mpm
on latest stable apache 2.4.6
we are using:
(we tried both inside and outside virtualhost: )
<Proxy fcgi://socket=%2fdev%2fshm%2ffpm-php.sock>
ProxySet timeout=3600
ProxySet connectiontimeout=3600
</Proxy>
ProxyPassMatch ^/(.*\.php(/.*)?)$
fcgi://socket=%2fdev%2fshm%2ffpm-php.sock/mobilnet.sk/$1 timeout=3600
connectiontimeout=3600
OR
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^/?(.*\.php)$ fcgi://socket=\%2fdev\%2fshm\%2ffpm-php.sock/path/$1
[P,L]
but none of them accepts the timeout:
[proxy_fcgi:error] (70007)The timeout specified has expired: [...] AH01075:

This patch removes hardcoded 30 second timeout from mod_proxy_fcgi and replaces
it with ProxyTimeout/Timeout.
