Revamp debug logs #816

jonjohnsonjr · 2020-11-06T01:04:26Z

Drop places that can log creds. May bring this back with build tags?
Introduce pkg/internal/redact to hold a context that signals we
should omit the body when dumping logs. Maybe this should live in
the logs package, but internal for now should be fine.
Stop logging the request and response body for blobs and token
responses.

I found req/resp dumps very useful.
The only time it wasn't useful was when the content type was a blob.

so I was doing something like this to download a layer into a file.

crane blob -v us-central1-docker.pkg.dev/ahmetb-demo/ahmetb-demo/busybox@sha256:9758c28807f21c13d05c704821fdd56c0b9574912f9b916c65e1df3e6b8bc572 > blobfile

and -v ended up printing the layer blob (garbage) into the log stream as well.

jonjohnsonjr · 2020-11-07T00:08:27Z

Trying to figure out a good way to actually filter out stuff you don't care about. We don't want to log the token response and we don't want to log binary blobs, but it's impossible to determine those from just the request or response in this context. We could do something janky like modify the context to tell the logger not to log certain requests...

jonjohnsonjr · 2020-11-07T19:40:18Z

I've implemented my janky suggestion to thread this through ctx.

Note some things:

cc @mattmoor this also includes timing info from the transport, which you may find useful

1. Drop places that can log creds. May bring this back with build tags? 2. Introduce pkg/internal/redact to hold a context that signals we should omit the body when dumping logs. Maybe this should live in the logs package, but internal for now should be fine. 3. Stop logging the request and response body for blobs and token responses.
