Problem

Tried to run cargo update with a large private project uses workspace and a bunch of crates.io patches.

This is the full stacktrace:

Really sorry you bumped into this. However, without any additional info it's hard to move forward. Do you think is it possible to reduce to a minimal reproducible example? Could you describe how complex you did patches? What was changed between the last successful build and this panicking? Thank you.

[dovahcrow]

@weihanglo sure I'll try to reduce it down.

This is very exciting! The terrible error messages is because I could not imagine how the code could end up in such a mess. Somehow you hit

cargo/src/cargo/core/resolver/mod.rs

Line 832 in a77ed9b

.map(|&c| (cx.is_active(c).expect("not currently active!?"), c))

if we can get a way for me to reproduce, I am very much looking forward to debugging this.

You may want to backup a copy of the index in cargo_home and the patches, as they are also inputs to resolution that may affects repoducabilaty. That being said the actual contents of your project should not affect this error, if you copy your cargo.toml and cargo.lock into a cargo new project you should have the same problem.

[dovahcrow]

Sadly yesterday, I refactored some of the dependencies; I forgot which special combination of the packages could cause the issue. I'll close this for now and open the issue once I encounter the problem again.

[hw0lff]

I just encountered this error too. I have created a minimal reproducible example @Eh2406
