Description Tony White 2010-05-07 15:34:51 UTC 
Description of problem:
php is unable to fopen. httpd it is started before name resolution.

Version-Release number of selected component (if applicable):
Apache/2.2.15 (Fedora)

How reproducible:
Every boot

Steps to Reproduce:
1. Boot your fedora LAMP server setup
2. Try to use an fopen php 5 function to retrieve a remote url using a php script (simplepie is a good one to try.)
3. Inspect the logs, there should be something like :
php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in ...
  
Actual results:
php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in ...
In the logs and the data from the url is not fetched.

Expected results:
Data from the url is fetched. No error message.

Additional info:
Restarting the httpd service solves the issue.
It is exactly this problem :
http://www.php.net/manual/en/function.fopen.php#33228
So if you reboot a fedora server, php fopen requests will not function because httpd is started before the name resolution occurs unless you restart httpd.

I have no idea if this bug should be against upstart or apache.

Anyway this bug doesn't rely on apache-commons-exec which is a Java library.
Changed "Component" field to "php".

For me, this is not a bug.

You are probably using NetworkManager, switch to network if you want a server with all daemon up in the right order.

Else (for a dev computer), don't start httpd à boot time.
Comment 3 Joe Orton 2010-05-08 13:13:12 UTC 
Agree with Remi.  If you want to stick with NetworkManager, you can do:

  # echo NETWORKWAIT=1 >> /etc/sysconfig/network

to force NM to wait for a network at bootup.
