/**

* @file
|
|
* Administrative screens and processing functions for the update manager.
|
|
* This allows site administrators with the 'administer software updates'
|
|
* permission to either upgrade existing projects, or download and install new
|
|
* ones, so long as the killswitch setting ('allow_authorize_operations') is
|
|
* still TRUE.
|
|
*
|
|
* To install new code, the administrator is prompted for either the URL of an
|
|
* archive file, or to directly upload the archive file. The archive is loaded
|
|
* into a temporary location, extracted, and verified. If everything is
|
|
* successful, the user is redirected to authorize.php to type in their file
|
|
* transfer credentials and authorize the installation to proceed with
|
|
* elevated privileges, such that the extracted files can be copied out of the
|
|
* temporary location and into the live web root.
|
|
*
|
|
* Updating existing code is a more elaborate process. The first step is a
|
|
* selection form where the user is presented with a table of installed
|
|
* projects that are missing newer releases. The user selects which projects
|
|
* they wish to upgrade, and presses the "Download updates" button to
|
|
* continue. This sets up a batch to fetch all the selected releases, and
|
|
* redirects to admin/update/download to display the batch progress bar as it
|
|
* runs. Each batch operation is responsible for downloading a single file,
|
|
* extracting the archive, and verifying the contents. If there are any
|
|
* errors, the user is redirected back to the first page with the error
|
|
* messages. If all downloads were extacted and verified, the user is instead
|
|
* redirected to admin/update/confirm, a landing page which reminds them to
|
|
* backup their database and asks if they want to put the site offline during
|
|
* the upgrade. Once the user presses the "Install updates" button, they are
|
|
* redirected to authorize.php to supply their web root file access
|
|
* credentials. The authorized operation (which lives in update.authorize.inc)
|
|
* sets up a batch to copy each extracted update from the temporary location
|
|
* into the live web root.
