feat(miniooni): minimal JavaScript-ing capabilities #1437

bassosimone · 2023-12-13T16:40:57Z

This diff implements part of my SplinterCon JavaScript demo (#1423). We only include minimal functionality here. The bare minimum to be useful when doing research.

Closes ooni/probe#2647.

Because this is experimental code and there's no commitment to productionize it, I have decided to create a specific subpackage internal/x that should host our in-tree experiments. (I will also mode dslx in there.)

This commit ensures we can parse integer values provided using OONI Run v2 descriptors into actual integers. Values are originally parsed as float64, so we need to add a specific conversion case for that scenario.

Noticed when preparing the SplinterCon demo. We should have the same name for the engine state directory for miniooni and ooniprobe. Otherwise, we need to tell people about this difference.

This is a minimal JavaScript interpreter invokable from miniooni, which seems helpful when doing research in difficult environments where an ordinary compile, ship, test, edit, compile loop is too slow. To implement this interpreter, we use a special purpose DSL that is easier to use from other languages than the current one.
