Description

http://wordpress.org/support/topic/164139?replies=1

OK, this might not be a WordPress problem exactly, but maybe someone could help me.

When I click the auto-update option for plugins, the page displays:

Warning: tempnam() has been disabled for security reasons in //wp-admin/includes/file.php on line 316


Is there a way to fix it?

Appears some hosts disable tempnam() all together, Might be worth simply using basename($url) as the filename in the upgrade folder.

It causes the plugin auto upgrade to fail.

attachment 6465.diff added.

  • Introduces wp_tempnam() to find a filename which is useable, based off a provided filename/url & optionally a path (Note: The args are not the same as PHP's tempnam, as the arguement order makes more sense in this fasion for WordPress's use)
  • Adds checks for getmyuid() and fileowner() before attempting to use them
  • And adds a filter to the filesystem method.
