If video support is turned off after videos have been uploaded, videos are still shown and cause an error when clicked

[Clint Byrum]

Test case:

Install mediagoblin with video turned on in
mediagoblin_local.ini:

media_types = mediagoblin.media\_types.image,
mediagoblin.media_types.video

Upload a video

Change mediagoblin_local.ini to have

media_types = mediagoblin.media_types.image,

Restart paster / lazyserver / celery / etc.

The video will be displayed, click it, you will get an error:

bitesized task: Try to reproduce this on current master and see what is happening. We need a current stack trace.

Not so simple task: We need to decide what should happen in the general case anyway: Should we just not show "not any more supported" media? Or a striped version? I really don't know.

(I don't know, why trac thinks I modified the description. I did not intend to.)

Updated traceback running on development server.

[Ben Sturmfels]

I've added an updated traceback repeating this on the current master. The list view displays ok, but the attached error occurs when attempting to view the individual page for a video.

I'd be happy to do some work on this, but a design decision is needed. How should non-supported media items be treated in list views, and how should they be treated on individual pages?

This situation should only ever arise for system administrators and the error message clearly describes the problem:

FileTypeNotSupported: MediaManager not in enabled types.  Check media_types in config?

One approach could be just to give administrators a management (shell) command to purge unsupported media. It should probably confirm what will be purged before it actually happens.

It seems to me that once a media type is disabled, items of that type should no longer show in list view. The details view should probably return HTTP 404 with content "[media_type] files are not enabled on this server."

I'm happy to attack this change if someone can confirm that this approach would be ok.

I'm not sure I agree with that approach. I don't really like the idea of hiding already-uploaded content (but hiding it is certainly better than auto-deleting it).

If my site has a lot of videos, and then I realize I don't have space for any more videos, or something happens and I can no longer transcode videos properly, I'd like a way to prevent further videos from being uploaded without affecting existing videos.

Maybe a compromise would be to add an additional config directive for each media type to enable/disable uploads of that media type. So if I want to allow video uploads, I could do something like:

[[mediagoblin.media_types.video]]
allow_upload = True #(default to true, so no need to explicitly add this line)

And if I want to keep existing videos but prevent more videos from being uploaded I could do:

[[mediagoblin.media_types.video]]
allow_upload = False

And then if I want to disable video all together I could remove the video media_type directive and then maybe we just hide the existing videos like Sturm suggests.

It would be also be worthwhile to check into whether bin/gmg dbupdate can complete successfully when videos exist in the database but the video media type is disabled.

Enabling/disabling uploads for a media type would be useful feature. Could you please add a separate ticket for that? This ticket is specifically about gracefully handling a media type plugin being entirely disabled, and we'll need that regardless of whether we can disable uploads or not.

Once a media type plugin is disabled, MediaGoblin doesn't actually know how to display that type of media at all. It is possible to still display some general information about the piece of media; such as title, description, author, license and date; but not the media itself. Perhaps we could still list the item and allow people to visit its detail page with some basic information, but display a message to say that the media itself cannot be displayed as it's type is unknown?

It would be also be worthwhile to check into whether bin/gmg dbupdate can complete successfully when videos exist in the database but the video media type is disabled.

Good thinking. I'll check that too. :)

I created #5392 to introduce the idea of disabling further uploads of an already-configured media type.

I like that idea better than throwing server errors or hiding the media from list view.
