topictree v2 broken #114

Closed MaxDz closed 8 years ago

MaxDz commented 8 years ago

The v2 API topictree call, which is the only one that returns article and video info (not in v1) is returning an error: 500: Error: Server Error / The server encountered an error and could not complete your request.

This began to happen at about the same time that the v1 topictree was being truncated, but is now fixed: issue 111

It looks like the v2 API just uses too much memory now for our poor servers to handle. We will have to figure out a way to improve that. Folks are looking into it!, though I'm afraid I can't give a timeline.

btw, you can get video information via the v1 API call. (That is the default if you don't specify kind=.) But there's no way I can see to get the article information without using v2.

Tnx. Hopefully you can find a fix; it was slow, but was usable until about the end of June.

The video info is there, but not the titles; we use the v2 to get them for arts/vids in our translation control tool dAlEK [I am in the es translation team]. So that we can show the whole hierarchy by domain/subject/topic/tutorial, and then all the items inside (exs/art/vid/descr) that we are working on.

Still no fix? We are stuck with the incomplete topictree from >1 month ago, and cannot update it :( Could there be another way to get the v2 json???

I'm really sorry about that -- we expected to be able to fix this properly sooner. I think @wchargin is going to put in a temporary fix today.

Hi @MaxDz—just pushed a fix that should let hopefully let it finish. (It does for me!) It may take longer than it used to, but should finish within a few minutes.

Sorry again for the inconvenience; holler if this still doesn't work!

Thanks everyone!!! We seem to be back in business... no, it did not seem to take longer than before; but no matter, we update only every few days.
