rosetta-what

This is a repro of a bug I hit with Docker for Mac with Rosetta enabled.

This brings in an old npm dependency called keypair which does crypto operations in pure Node. It is "slow", but in Rosetta it is either 4+ orders of magnitude slower or it is stuck in a loop - it never finishes.

usage

docker run --platform linux/amd64 jbinto/rosetta-what

With Use Rosetta for x86/amd64 emulation on Apple Silicon disabled, this returns in a few seconds:

With Use Rosetta for x86/amd64 emulation on Apple Silicon enabled, the container takes 100% CPU and "never" returns. Longest I waited was 14 hours.

build

docker buildx build --platform linux/amd64 --push -t jbinto/rosetta-what .

n.b. On an Apple Silicon device, using buildx without --push, images remain in the build cache; was easier for me just to push to dockerhub and run it back than look up shas
