Invalid page titles are appearing in the top_articles data
Closed, ResolvedPublic5 Story Points


"-" is not possibly a valid page - in fact, it's sort of the ABSENCE of a valid page - and yet it appears in our top articles counts for (at least) enwiki, on mobile and overall, on 2 October.

Presumably this is an implementation problem somewhere (possibly in the PV def?)

We'll remove "-", as a special case, from the data that's computed for the top endpoint. That means we'll be removing the probably miniscule number of pageviews to the actual redirect page titled "-". But there really is no other way.

Huh. The pageID approach won't work? :(

We'd love to get pageId into each of our pageview requests, but that's not happening any time soon. When we have that, yes, we can add poor old back to the pageview stats :)
