1267436 - Rust API for Debugger instances

Status: NEW

(Core :: JavaScript Engine, enhancement, P3)

Description

[Jim Blandy :jimb]

So that Servo can use SpiderMonkey's debugging API, SpiderMonkey should provide a Rust API for working with Debugger instances.

Can you detail what do you mean by a "Rust API", from what I understand the Debugger API is made to be used from JS, how would it be different?  Is there any reasons to have a different API for Servo than the one we used for Gecko?

Comment 2

I certainly don't intent to ask a Rust API directly in SpiderMonkey, but I would like us to avoid having to host JS code to debug JS code. Given that the Debugger API is written in C++, it makes sense to me that we should be able to use it directly from C++.

See bug 1263317 -- the summary is that Servo doesn't want to ever support privileged JS, so the existing way we provide an interface to Debugger (via a JS interface in privileged compartments) is not going to fly. Instead, we are adding an alternative interface to the same Debugger infrastructure for Servo's use.

Yeah, this discussion belongs on bug 1263317, let's continue it there if necessary.

Moving to p3 because no activity for at least 1 year(s).
