Commons app version:

2.8.0 beta

Would you like to work on the issue?

Pref not

It might be because the information from the API's hasn't been fetched, and the current session has expired.
Possible steps Taken:
1) Increase the session time. This might reduce the probability of session expiry.
2) Display a message regarding the session expiry and prompt them to try again later

I don't think there would be any issues with increasing the session time, but are we able to do that from our end? @maskaravivek

[maskaravivek]

Yup, I don't think session duration could be controlled by the clients.

@tanvidadu which token are you using. In particular crsf token can be used once and is valid just for 10 seconds from the time it was generated.

The change that I did for the session management might affect all API calls that require an edit token. I will review the session management logic this Sunday and see if the comments left by Tgr could be used to modify some of our flows.

[tanvidadu]

I didn't explicitly mention any token while making api calls so I am not sure which token I am using.
Is there any way to find it out?

[maskaravivek]

Oops, I forgot that you are not using a MediaWiki API.

The API that you are consuming doesn't depend on app's session. Its an anonymous API.

I guess the best you could do is gracefully handle the error by showing a snack bar or toast.

Also, we can probably check with @urbanecm if he has any statistics around urbanecmbot/commonsmisc/feedback.py failure rate and latency.

Hello everyone,

as of now, I have received 11 requests regarding said user, access.log (filtered to focus on this case) is on https://pastebin.com/raw/UgQf7NHa. Sadly, when writing the API, I've forgot to reflect error not only in JSON being returned to the called but also in the HTTP status code. Then, I have absolutely no clue if those requests were successful or not. I've updated the API so https://tools.wmflabs.org/urbanecmbot/commonsmisc/feedback.py?fetch=deletedUploads (invalid request, no user was given) gives 400 Bad Request (see following example how it will be recorded in the logs)

10.68.21.81 tools.wmflabs.org - [12/Aug/2018:15:13:01 +0200] "GET /urbanecmbot/commonsmisc/feedback.py?fetch=deletedUploads HTTP/1.1" 400 62 "-" "<user agent>"
Last log in error.log (recording raised exceptions not handled in the program, like mysql server down) is from Jun 27 (errors raised by everything residing under tools.wmflabs.org/urbanecmbot), so at least no such error is causing this.

Requests like https://tools.wmflabs.org/urbanecmbot/commonsmisc/feedback.py?user=Ainali varies in time. I've tried on several users:

• Ainali: 0m17.461s
• Martin Urbanec: 0m0.619s
• Jagro: 0m4.632s

I can try to optimalize the queries to not take 17 seconds...

Martin

Thanks so much for your help, @urbanecm ! :) I'll ask the user to try again.
