We are still missing a key that tells us whether a given field is actually revisionable. This metadata is good to have anyway, but in particular it helps all the storage internal code to know how to query or load the field.

Apart from that it tells anyone using the entity revision API which fields it will actually make use of, without urging people to go through various internal.

Demoting for now, it doesn't seem like this has really come up since filing this.

This is needed for #1498720: [meta] Make the entity storage system handle changes in the entity and field schema definitions - this qualifies it even as beta-blocker now. I'll roll a patch.

Looks good.

I guess we should mark all revisionable fields out there as such now :)

    Why is this TRUE by default? Is there any reason? I checked and isTranslatable() simply does !empty($this->definition['translatable'])

Here is a re-roll according our discussions. Not done yet (has a fail), and needs to incorporate definitions for all other content entities.

This key perhaps could even be used to avoid creating revision tables with dupe data in D8. This was quite an issue in d7 (https://drupal.org/project/field_sql_norevisions)

Since "revisionability" check is made on the hardcoded 'label' entity key, similarly the "translatability" check could be made with an in_array() on an inlined, hardcoded list of keys. No need for the $untranslatable_keys var above, it feels disconnected with the comment that precedes its definition and hinders readability IMO.

Other than that: don't we want to default to TRUE ?

ok, moved to in_array(). It's not as efficient, but its minor and the result is cached anyway.

Attached patch should fix the tests. Unfortunately I had to remove the nice simple little check to ensure all entity keys are there as well, but this would require us to redo most of entitymanager unit test. So removed this for being able to move on here.

Other than that: don't we want to default to TRUE ?

That was my initial suggestion (see above), but after some discussion with berdir, tstoeckler and xano we agreed to default to FALSE. You either have to disable it for entity-key-fields manually, or you have to enable it for most others manually if it should be explicit. So it does not matter much but with the default of FALSE it's at least consistent with translatability.

Looks good to me, would it make sense to add a (qualified) @todo about restoring the exception and refactoring EntityManagerTests as needed?

Great! Have nothing to complain about. I agree with #14. I would find it unintuitive to have to ->setRevisionable(FALSE) for stuff like nid, etc.

@yched, you can obviously downgrade if you object, but marking this RTBC.

Oops, crossposted with #18. Leaving at RTBC?!

Yep, let's leave the decision to a committer.
