Notes

In dewiki, I am getting a couple of exceptions that make diffs and (partially) page histories inaccesible, e.g. [XjvqYgpAMFAAAH7XbeYAAABH] 2020-02-06 10:28:51: Fatal exception of type "Wikimedia\Assert\ParameterAssertionException".

I stumbled upon this when doing queries on the dewiki actor_revision table, in which the row with actor_id=10630425 has a weird actor_name that just seems to be broken. Turns out that I get a Wikimedia\Assert\ParameterAssertionException when trying to access the three diffs that this actor made, or when accessing the corresponding page histories.

Quick links to diffs and histories that yield this exception:

All diffs stem from imports from ruwiki to dewiki.

T232451 - The same issue also found on action=info

Krinkle moved this task from Untriaged to Feb2020/1.35-wmf.18 on the Wikimedia-production-error board.

I'm going to go ahead and close this as a duplicate, since it's basically the same thing. That revision has a username containing a newline, apparently from an import from back in 2014.
