Read timeout after marking pages for translation
Closed, ResolvedPublic

Description

I recently received several "Wikimedia Foundation" errors after carrying out translation admin actions. The action completed successfully in each case, but the page that is supposed to be loaded afterwards threw a read timeout. Listing the log entry and the corresponding error message for three cases:

It's similar to https://bugzilla.wikimedia.org/show_bug.cgi?id=41131 ("Timeout when sending translation notification")
However, that bug was closed as fixed half a year ago, and indeed didn't occur for me since at least the beginning of this year, and also it did not happen when marking pages for translation. So it seems reasonable to assume that the reason is different now; hence filing it separately.

Yeah, this seems similar to the CN bug I filed earlier (bug: 53674 ) where a save there times out constantly (or takes a long time and almost times out). Fundraising thinks it's because of a translation job running on save as well. The Mark Translation time outs were a nightmare while setting up the privacy policy discussion yesterday (and as we tweak it during the discussion now) and it's basically gotten to the point that we never don't time out from a markup (I think I've had once where we didn't of a good 30+ markups in the past 24 hours).

Bug 53674 has a patch now, probably worth to recheck once it's merged.

Seeking a bit of an update on this if possible. I believe something was said in a separate email thread about some possible ops needs for this (new translation servers or something like that) but as I was not on that thread not sure exactly what the situation is.

Patch in bug 53674 got merged on Friday and will likely be deployed today (Monday afternoon PST time) - retesting highly welcome after that.

Aye, sounds like this got pushed (it's deployed but not enabled) that particular patch should not effect this bug however. It works by just making the CN save async with the translation task (and not fixing the speed of the translation task issue).

Thank you for filing this bug, Tilman. I've been hitting the same issue on Meta-Wiki.

I tried Special:NotifyTranslators and it was very quick, nowhere near timing out. If it does time out for you, can you please list the parameters you used in a separate bug, as that probably has different cause than when marking page for translation.

OK, filed as https://bugzilla.wikimedia.org/show_bug.cgi?id=55397 after this happened again.
