Question: How to debug using docker & CI shell script? #20488

Hi,

my PR #19245 fails on several platforms so I have attempted to run on my Ubuntu 20.04:

FILE_ENV="./ci/test/00_setup_env_native_tsan.sh" ./ci/test_run_all.sh

as per instructions in https://github.com/bitcoin/bitcoin/tree/master/ci.

I can reproduce issue on CI which is great news. However, I would love to modify source code and re-run the FILE_ENV="./ci/test/00_setup_env_native_tsan.sh" ./ci/test_run_all.sh script or attach to docker to run a failing functional test again so that I can debug it easier.

Does anybody have a workflow for this?

Notes:

• I've tried docker attach <container ID> but it's not possible to simply execute test/functional/wallet_hd.py as it fails in that docker instance because it is supposed to be run somehow differently (that's as much as I gather from studying ci/test_run_all.sh).

The CIs compile from a make dist tarball, so if you want to modify the code, you'll need to modify the one in ./ci/scratch/... inside the docker

Or you could write a Dockerfile with the desired environment and mount the source there.

I will tinker with it. Thank you for the help.
