extension API for "replace" does not trigger database updates

[SarahG (FountainTribe)]

I am using the native extension APIs to update the version of various extensions. My current code is:
 

Code: [Select]

$manager = CRM_Extension_System::singleton()->getManager();
$manager->refresh();
$manager->replace($replace_parm);
But when I go to the page at: http://mygroup.org/civicrm/admin/extensions?reset=1

I get an alert reading "Your extensions require database updates. Please execute the updates."

When I read the code comments for the replace function on GitHub ( https://github.com/civicrm/civicrm-core/blob/4.4/CRM/Extension/Manager.php) I see the following:
  * Install or upgrade the code for an extension -- and perform any
   * necessary database changes (eg replacing extension metadata).
   *

What should I be doing so that the extension database updates get triggered from within my code?

Ah, those code comments are bit misleading. Let's rephrase:

• CRM_Extension_Manager::replace() performs any DB updates for internal state of the extension-manager -- e.g. inserting/updating records in civicrm_extension or resetting cached info about the extension file structure.
• For DB updates defined by third-party developers (e.g. using hook_civicrm_upgrade or civix's "Upgrader" class to define a custom SQL table), one calls CRM_Extension_Upgrades. In 4.5, this is most easily done with the "Extension.upgrade" API. (I suspect it wouldn't be very hard to backport.)
