So, serde seems to be downloading and running a binary on the system without informing the user and without any user consent. Does anyone have any background information on why this is, and how this is supposed to be a good idea?
dtolnay seems like a smart guy, so I assume there is a reason for this, but it doesn’t feel ok at all.
If the executable were easily reproducible from the source code, then yes, downloading a precompiled binary would be akin to executing code in
build.rsor a proc macro. The fact that it’s not makes these very different, because it makes your suggestion of “vet[ting] their packages themselves” impossible.Maybe I’m missing something, but I’m not seeing where in serde we’re downloading a precompiled binary. I see a script we can execute ourselves in the repository and an alternative serde_derive that uses that executable (after we compile it), but not where the actual published package has the executable.
It’s possible I’m missing something here though.

ᐸwhich is a replacement character because Lemmy escapes the real one. This is annoying.There, you will see that this file exists:
Yes, that’s a pre-built binary in the crate source release. It’s that bad.
Looks like I missed that, I was checking locally but I must have been checking an outdated version of the package. I’d feel better about it if it compiled on the user’s machine, which is the impression I was getting.
