php5-curl install should restart apache not reload it

[ironstorm]

Binary package hint: php5

Installing php5-curl, the post-install script does an Apache2 "reload" which refreshes the configuration, but does not cause the new libs to be loaded into memory. The result is any PHP page using curl will crash until Apache2 is "restarted".

Install:

aptitude install php5-curl

Workaround:
sudo /etc/init.d/apache2 restart
 * Restarting web server apache2

The problem is then resolved.

Hi ironstorm, thanks for taking the time to file this bug report and help us make Ubuntu better!

I've just done some tests with this, and I cannot confirm the issue on natty..

I created a PHP file in the webroot of apache:

<?php

$ch = curl_init();

Then hit it without curl installed.. and I got a 500 error as I would expect.

I then installed php5-curl, and refreshed the page. As soon as the libapache2-mod-php5 trigger reloaded apache, the page started returning a 200.

This is in apache's error log:
[Sat Apr 16 08:23:00 2011] [error] [client 127.0.0.1] PHP Fatal error: Call to undefined function curl_init() in /var/www/curl.php on line 3
[Sat Apr 16 08:23:00 2011] [notice] Graceful restart requested, doing restart
[Sat Apr 16 08:23:01 2011] [notice] Apache/2.2.17 (Ubuntu) PHP/5.3.5-1ubuntu6 with Suhosin-Patch mod_wsgi/3.3 Python/2.7.1+ configured -- resuming normal operations

It does seem to happen on maverick, but I can't seem to find the exact changelog item that has made this a reality.

As such, I'm going to mark this as Fix Released, and open a task against Maverick that is Confirmed, importance Low.

Thanks Clint, I'm glad to hear it's already fixed for the next release. :D

maverick has seen the end of its life and is no longer receiving any updates. Marking the maverick task for this ticket as "Won't Fix".
