1 update.compare.inc | _update_process_info_list(&$projects, $list, $project_type, $status) |
Populates an array of project data.
This function iterates over the list of installed modules, themes and layout templates, and groups them by project type and status.
Some parts of this function assume that enabled projects are always processed first, and if disabled projects are being processed (depending on the 'update_disabled_extensions' setting, as configured under admin/reports/updates/settings), those are only processed after $projects has been populated with information about the enabled code. Projects that are set as hidden are always ignored.
This function also records the latest change time on the .info files for each module, theme, or layout template. This timestamp is used when deciding if the cached available update data should be invalidated.
Parameters
$projects: Reference to the array of project data of what's installed on this site.
$list: Array of data to process to add the relevant info to the $projects array.
$project_type: The kind of data in the list. Can be 'module' or 'theme' or 'layout'.
$status: Boolean that controls what status (enabled or disabled) to process out of the $list and add to the $projects array.
