The problem:
- Currently, if we want to change an exercise description or solution or test, we restart
learn-ocaml build serve --repo=… - This rebuilds every exercise, which can be time-consuming;
- And in the meantime, the learn-ocaml backend is down (HTTP 502 Bad Gateway or so)
Wanted solution:
- It would be nice to ensure that the server responds immediately at the second build, even if it needs to rebuild all exos.
- Then when the build is over, atomically set the newest directory as the one to be served.
Considered alternatives:
- Does this require several threads? Would this benefit from OCaml 5?
