Core Update

Provides the capability to update Drupal 7 core from your web browser.

This module preceded the official work of the Automatic Updates initiative. Equivalent and supported functionality is now available through the automatic updates module.

This module may be installed and enabled like a standard Drupal 7 module. Once enabled, a button is added to the Update tab of the Available Updates report (/admin/reports/updates/update) whenever there is a newer release of Drupal 7 than the version your site is running.

This is a new module. You should use it if you are looking for an easier way to carry out the chore of updating your site, but you also have alternative means to restore your site if something goes horribly wrong.

After a successful update, you'll be redirected to Drupal's database schema updates page. This page will take care of any corresponding database updates.

The most important things to know about this module are:

• Rather than downloading an entire release .zip and re-installing all of Drupal, it downloads a release artifact containing only the changes that need to be applied between your Drupal release and the current one. While this allows the update to progress as quickly and non-disruptively to your site as possible, it currently means the code changes are fetched from a site that's not affiliated with the Drupal Association.
• It does not yet have support for updating your site over FTP. Your Drupal core files must be writable by the webserver. If a file that needs to be changed is not writable, the module will roll other files back to their pre-update state and your site will continue to operate under the old version until the problem can be corrected.
  • The underlying Curator project has FTP support; if you need this feature please contact the maintainer to help gauge demand.

While Drupal Core files are being written, Drupal is not bootstrapped by this module. This offers some protection against updates failing partway through because Drupal is itself in a partially-updated / inconsistent / broken state. A separate entry point ("index.php") script distributed with this module handles the requests from your browser necessary to perform the update during this time.
The file drupal_curator.php must be allowed to run as a php script for this module to operate.
