There was a problem hiding this comment.
Good catch. However I think this makes the assumption that r==nil if err!=nil. Seems unlikely to be a relevant response if there's an error, but that's a potential gap we'd be missing. In any case: this seems fine. We can address if we wanted r.StatusCode; or maybe have a fallback.

Yeah, based on my dive into the code (and slight exploration into the net/http) I had a hard time finding a case where |

Use int(goAwayErr.ErrCode) instead of r.StatusCode when building the push.Response on an http2.GoAwayError. When a GOAWAY frame is received, http.Client.Do returns a nil response, so accessing r.StatusCode would panic. Using the HTTP/2 error code from the GoAwayError itself is cleaner and matches the fix merged upstream in micromdm/nanomdm#248. Also adds TestGoAwayErrorNoPanic — a regression test using a mock Doer that returns a GoAwayError — to prevent future regressions. Bahtya

This PR fixes a subtle (and most likely never hit) code panic.
The code path in the nanopush provider, used the r.StatusCode, which is not available. I'm not sure if we are okay with the error being built assumes it's an HTTP status code, but we instead pass the GoAway error code.
