@Fabien Maybe in a separate diff? I also need to update docs/build-*.md on how to build Chronik, or add a docs/build-chronik.md

Can you please add a doc/chronik.md that redirects to this readme ?

This is a bad workflow because now only people with write access to the npm repo can develop on any app that will require a change to the mock and push the RC. This is a clear move backward.

Fair enough, let's the factorization happen in a follow up and keep only the proper child process shutdown for this (large enough) diff.

The tests are broken, clearing my queue

Standardize before and after methods with functions.

Fix shellcheck

Rebase

This still need to be factorized so we don't repeat the same code in all tests, but otherwise lgtm

not sure what to make of this. build log seems to be failing in different way vs before but this is just from memory

That's still the same issue, so the cause is something else (or there are several causes).

Only build chronik for linux

Forward gcc libs to LD_LIBRARY_PATH, fix typos

Remove spurious newline

@bot gitian-linux

Please also update gitian-linux.yml

PEBCAK issue

For some reason the gitian build is no longer deterministic, I need to investigate
