Event Timeline

Don't worry about the test failures, they are not related to your changes. I just restarted them.

You don't need to make this configurable; most API endpoints aren't. (eg. look for limit in swh/web/api/views/origin.py)

So, should i limit the request directly inside the endpoint?

Yes, like you already do, it just doesn't need a config value

A new test should be added to check the 413 code is returned when the input pid list is too large..

swh/web/common/exc.py

LargePayloadExc seems a more generic name to me.

swh/web/config.py

Adding this in configuration is not a shocker to me.

pids_list_max_size is also more explicit.

swh/web/config.py
49

It would be hard to test without a config value, i can't get the limit from the endpoint

swh/web/config.py
49

Alright. But use a reasonable default value then (eg. 1000 or 10000)

well, this isn't great, they should be configurable :-)

(but ack, I agree it is pointless to diverge and make only one of them configurable at this point)

making all endpoints configurable might be a good easy hack task to file

limit is set inside the endpoint
