interface UpdateManagerInterface (View source)

Manages project update information.

Constants

NOT_SECURE

Project is missing security update(s).

REVOKED

Current release has been unpublished and is no longer available.

NOT_SUPPORTED

Current release is no longer supported by the project maintainer.

NOT_CURRENT

Project has a new release available, but it is not a security release.

CURRENT

Project is up to date.

Methods

array
getProjects()

Fetches an array of installed and enabled projects.

fetchDataBatch(array $context)

Processes a step in batch for fetching available update data.

refreshUpdateData()

Clears out all the available update data and initiates re-fetching.

array
projectStorage(string $key)

Retrieves update storage data or empties it.

Details

array getProjects()

Fetches an array of installed and enabled projects.

This is only responsible for generating an array of projects (taking into account projects that include more than one module or theme). Other information like the specific version and install type (official release, dev snapshot, etc) is handled later in update_process_project_info() since that logic is only required when preparing the status report, not for fetching the available release data.

This array is fairly expensive to construct, since it involves a lot of disk I/O, so we store the results. However, since this is not the data about available updates fetched from the network, it is acceptable to invalidate it somewhat quickly. If we keep this data for very long, site administrators are more likely to see incorrect results if they upgrade to a newer version of a module or theme but do not visit certain pages that automatically clear this data.

Return Value

array

An associative array of currently enabled projects keyed by the machine-readable project short name. Each project contains:

  • name: The machine-readable project short name.
  • info: An array with values from the main .info.yml file for this project.
    • name: The human-readable name of the project.
    • package: The package that the project is grouped under.
    • version: The version of the project.
    • project: The Drupal.org project name.
    • datestamp: The date stamp of the project's main .info.yml file.
    • _info_file_ctime: The maximum file change time for all of the .info.yml files included in this project.
  • datestamp: The date stamp when the project was released, if known.
  • includes: An associative array containing all projects included with this project, keyed by the machine-readable short name with the human-readable name as value.
  • project_type: The type of project. Allowed values are 'module' and 'theme'.
  • project_status: This indicates if the project is enabled and will always be TRUE, as the function only returns enabled projects.

fetchDataBatch(array $context)

Processes a step in batch for fetching available update data.

Before calling this method, call UpdateManagerInterface::refreshUpdateData() to clear existing update data and initiate re-fetching.

Parameters

array $context

Reference to an array used for Batch API storage.

refreshUpdateData()

Clears out all the available update data and initiates re-fetching.

array projectStorage(string $key)

Retrieves update storage data or empties it.

Two very expensive arrays computed by this module are the list of all installed modules and themes (and .info.yml data, project associations, etc), and the current status of the site relative to the currently available releases. These two arrays are stored and used whenever possible. The data is cleared whenever the administrator visits the status report, available updates report, or the module or theme administration pages, since we should always recompute the most current values on any of those pages.

Note: while both of these arrays are expensive to compute (in terms of disk I/O and some fairly heavy CPU processing), neither of these is the actual data about available updates that we have to fetch over the network from updates.drupal.org. That information is stored in the 'update_available_releases' collection -- it needs to persist longer than 1 hour and never get invalidated just by visiting a page on the site.

Parameters

string $key

The key of data to return. Valid options are 'update_project_data' and 'update_project_projects'.

Return Value

array

The stored value of the $projects array generated by update_calculate_project_data() or \Drupal\update\UpdateManager::getProjects(), or an empty array when the storage is cleared. array when the storage is cleared.
