This has an issue. If two applications are using the tz library and each of them add to their own tree, they can probably race each other. It may be better if those are started under the Tz supervision tree and configured using the app environment. /cc @sasajuric
Correct. But please keep in mind :erlang.get(:elixir_compiler_pid) is private API. We will have a Code.can_await_modules_compilation? in Elixir v1.11. So I recommend adding a TODO to use that instead in the future.
Modules are purged after recompilation:
If modules always have the same name, you don’t need to purge them. The VM will do it automatically the next time you load them. If you want to purge to reduce code size, then I would recommend purging it after some period of time - like a minute - as otherwise you may kill processes currently running the purged code.
