I recall it's not used for the content hashes computations and something about us adding that value...
@vlorentz must have a clearer view than me on the subject.

But yeah, the inconsistency is not good and we should have comments on those kind of instructions...

vlorentz requested changes to this revision.Sep 2 2020, 10:29 AM

it's fine, we're even doing it in content_find already. I just forgot these.

Could you add tests, though?

Turns out ctime field is not returned by content_get in the postgresql storage but only by content_find. So I will revert that change.

anlambert updated this revision to Diff 13645.Sep 2 2020, 2:54 PM

Do not modify content_get implementation, the fix is only needed for content_find.

vlorentz added a comment.Sep 2 2020, 2:56 PM

Looks like you fixed content_get_partition, not content_find

vlorentz added a comment.Sep 2 2020, 2:57 PM

And wasn't content_find the one that was already fine, anyway?

Right, I mixed up the functions. So in fact ctime should be discarded by content_get_partition like in the postgresql storage, correct ?

Damn, i forget that part each time...

So in fact ctime should be discarded by content_get_partition like in the postgresql storage, correct ?

yes, that'd be my opinion as well.
