/**
|
|
* @file
|
|
* Administrative screens and processing functions of the Update Manager module.
|
|
*
|
|
* 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 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
|
|
* update, 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/ready, a landing page which reminds them to backup their
|
|
* database and asks if they want to put the site offline during the update.
|
|
* 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.
