This module defines a new content entity type `fixity_check`. This entity is used as an audit trail for fixity checks performed on a related `file` entity. Wherein the revisions of the `fixity_check` record the results of previous checks against that `file` entity. This modules requires and enforces the following constraints on `fixity_check`entities: - **Must** be related to a `file` - `file` relations **must** be unique - `file` relation **cannot** be changed after creation - `performed` and `state` properties **cannot** be modified after creation. Users with the permission `Administer Fixity Checks` can: - Manually perform checks - Manually remove `fixity_check` entities and their revisions - Manually mark files as requiring periodic checks - Generate `fixity_check` entities for all previously existing files Users with the permission `View Fixity Checks` can: - View fixity audit log of Media entities A `cron` hook is setup to automatically mark files as *requiring* periodic checks. As well as performing those checks on a regular basis. Email notifications can be configured to alert the selected user of the status of all performed checks on a regular basis or only when an error occurs. Requirements ------------ [](#requirements) This module requires the following modules/libraries: - [filehash](https://www.drupal.org/project/filehash) Configuration ------------- [](#configuration) The module can be configured at `admin/config/fixity`. Drush ----- [](#drush) A number of drush commands come bundled with this module. ``` $ drush dgi_fixity:clear --help Sets the periodic check flag to FALSE for all files. ``` ``` $ drush dgi_fixity:generate --help Creates a fixity_check entity for all previously created files. ``` ``` $ drush dgi_fixity:check --help Perform fixity checks on files. Options: --fids[=FIDS] Comma separated list of file identifiers, or a path to a file containing file identifiers. The file should have each fid separated by a new line. If not specified the modules settings for sources is used to determine which files to check. --force Skip time elapsed threshold check when processing files. ``` Installation ------------ [](#installation) Install as usual, see [this](https://www.drupal.org/docs/extending-drupal/installing-modules) for further information. Additionally after this module is first enabled, you will need to generate `fixity_check` entities for all pre-existing `file` entities. This does not require that the checks are performed, only that one `fixity_check` entity exists for every applicable `file` entity in the system. This can be done with `drush`: ``` drush dgi_fixity:generate ``` Or via the admin form on the page `admin/config/fixity/generate`.
