Generate Service Image Action not triggered by migration

[seth-shaw-unlv]

Running the migration results in UNLV Images with Media Files tagged as Preservation Masters but this doesn't trigger the generate_a_service_file_from_preservation_master action. This requires us to manually select the migrated content items in the UI and initiate the action after the migration completes. Hardly ideal.

Gathering resources.

• MigrateEvents API We will want to use the PostRowSaveEvent on claw_image.
• Change records: Events added to the migration process
• Example, with POST IMPORT
• StackOverflow example of PreImport

Ack, it also isn't triggering Fedora and triple-store indexing....

[seth-shaw-unlv]

I may have been barking up the wrong tree. The milliner log (/logs/islandora/milliner.log) starts displaying a lot of errors when the current migration configuration runs. So, events are being triggered, but not properly.

E.g. (sans JWT auth entries, which were all successful)

Note that the Gemini calls in these entries don't actually work.

Needs more debugging.

Discovered that drush doesn't automatically pull in the site URI which caused the emitted events to have the wrong URL. Running drush with the option -l http://localhost:8000 solves that part.

More testing to come.

[seth-shaw-unlv]

Derivatives are being generated by Houdini, but are not getting saved back to Drupal when using Drush. It is probably related to how AuthenticationGuardToken is being set. Migrations run when logged in as admin will show in the houdini log (/var/log/islandora/houdini.log) as:

Symfony\\Component\\Security\\Guard\\Token\\PostAuthenticationGuardToken: PostAuthenticationGuardToken(user=\"admin\", authenticated=true, roles=\"authenticated, administrator\"))","authenticator":"Islandora\\Crayfish\\Commons\\Syn\\JwtAuthenticator"} []

But when using drush the PostAuthenticationGuardToken part will change to:

(user=\"\", authenticated=true, roles=\"anonymous\")

[seth-shaw-unlv]

Drush used to have a user switch to run commands as another user, but it was removed. A thread recommends using AccountSwitcher, but it isn't clear to me how to use it. I attempted to use the AccountSwitcher in a Migrate PreImport Event subscriber, but that didn't appear to work (the Tokens didn't change).

[seth-shaw-unlv]

I finally got AccountSwitcher to work using a drush pre-command. The UserSession constructor needs the uid, name, and roles for the JWT auth to work. (UserSession doesn't infer the other properties from the uid.)

[seth-shaw-unlv]

Image generation isn't working on a stock claw_playbook. Reopening the issue although I probably won't do anything with it for the time being since users can successfully trigger derivatives using the UI Content page.

[seth-shaw-unlv]

Actually, it is creating them. Perhaps I didn't give it enough time to process last time.
