File and media libraries deduplication

[antonioribeiro]

A nice addition would be not to let people to upload duplicate image files to the libraries. Just compute and store a hash of the file during upload, and search for the hash before adding anything to it.

Maybe also add a configuration key to that too, because sometimes people might want to have duplicates instead.

I get what you're doing here, but my experience has shown that this is not always a great idea. For example, if you have a particular image that is used across numerous pieces of content, and you delete that image - all content would be affected, which may not be ideal. I learnt this when we used a similar sort of filesystem mechanic on our SaaS platform - users would delete a file, and not realise they're affecting content elsewhere.

I just sent a PR to do it.

Feature is, obviously, disabled by default.

If user's behaviour is a concern, I believe it's not really hard to prevent files from being deleted if media_id count on mediables is > 0. People will have to delete all related content before deleting the media.

That's actually already the case, media and files can't be deleted if they are related to anything.
