I take it you didn't read the article?

It turns out that "the threadiverse" is not "Threads".

I think you vastly overestimate the separability of these systems.

Picture 10,000 lines of code in one method, with a history of multiple decades.

Now picture that that method has buried in it, complex interactions with another method of similar size, which is triggered via an obscure side-effect.

Picture whole teams of developers adding to this on a daily basis in realtime.

There is no "meaningful progress" to be made here. It may offend your aesthetic sense, but it's just the reality of doing business.

rerere is a lifesaver here.

(I'm also a fan of rebasing; but I also like to land commits that perform a logical and separable chunk of work, because I like history to have decent narrative flow.)

Given the widespread existence of wasm sandboxing, rustc itself might want to think about alternative strategies for running compiler plugins. I suspect there'd be a performance hit with such an approach, but wasm tooling is getting really good; perhaps it is minor.

Apology appreciated, but unnecessary.

I don't want to derail a useful tool. It's worth going a bit beyond "hope" as a strategy, however, and thinking about if (how) this might be exploited.

I doubt anyone will be mining crypto in your sandbox. But perhaps you should think about detection; might it be possible to mask a malicious crate with a second that attempts to detect sandboxed compilation, for instance?

In any case, I think this still looks exceedingly interesting in the typical case, which is of detecting the impact of bugs from non-malicious actors.

I think you're trying to handwave at someone who knows more about the steganographic watermarking approach than you do.

Given the existence of macros, doesn't this let package maintainers run arbitrary code in the painter sandbox?

The opposite of "goth" is "ostrich"?

Yeah, I can see that.

In the UK, she has some claim to shared equity.

I had a small X.25 network as combination coffee-table and space-heater at one point; this was before most homes had internet. It almost cost me a divorce.

Doesn't need to be a "traditional" container. Modulo noisy-neighbour issues, wasm sandboxing could potentially offer an order of magnitude better density (depending on what you're running; this might be more suited to specific tasks than providing a substrate for a general-purpose conpute service).

That's not correct, but it shouldn't preclude you from applying defence in depth.
