v2:interceptors/logging: allow to separate request response payload logging #442

michaljemala · 2021-07-13T22:11:47Z

Logging payloads of requests on the server-side and similarly of responses on the client-side is a pretty common and desired use-case. However, logging by default payloads of both requests as well as responses in both scenarios is IMO not a very common requirement.

Consider the following PR to enable more granular control of what to log and when. This is achieved by using a special PayloadDecison type having the following values:

NoPayloadLogging - Payload logging is disabled.
LogRequest - Only logging of requests is enabled.
LogResponse - Only logging of responses is enabled.
LogRequestAndResponse - Logging of both requests and responses is enabled.
The PayloadDecison is to be used instead of the original bool by the logging.ServerPayloadLoggingDecider and logging.ClientPayloadLoggingDecider.

NOTE: I quickly put this together to see whether it could be considered a valid approach, thus please excuse the lack of additional unit tests. I will be glad to add those once the approach is approved.

I quite like this, but it was @bwplotka who refactored these, so I would prefer to have his input.

yashrsharma44

Functionally - I think using a switch case would make this code easier to read and maintainable. Otherwise looks good to me!

Hi @michaljemala !

This PR looks good to me, can you run make lint for fixing the CI changes required?
Otherwise looks good to me.

yashrsharma44 · 2021-08-02T17:07:24Z

cc'ing @bwplotka for the inputs 😄

yashrsharma44 · 2021-08-03T06:46:11Z

Seems like the CI build needs approval for first time contributors - https://github.blog/changelog/2021-04-22-github-actions-maintainers-must-approve-first-time-contributor-workflow-runs/

michaljemala · 2021-08-05T09:30:11Z

Hi @yashrsharma44 is there anything else on my side to be done?

yashrsharma44 · 2021-08-05T12:01:08Z

We are blocked on @bwplotka's review. Let me get back to him when he is free.

LGTM, only minor nit and lint error 🤗

Thanks!
