cargo upgrade gets stuck at "Updating 'https://github.com/rust-lang/crates.io-index' index"

[VorpalBlade]

When I run cargo upgrade it gets stuck at Updating 'https://github.com/rust-lang/crates.io-index' index (for at least 10 minutes). cargo update is fast, as is other, built in, cargo operations.

It appears that cargo upgrade isn't using the sparse index properly, that could have something to do with it. It still seems strange it would get stuck for that long though, as I'm fast internet (150 mbit/s down) and not behind any sort of corporate proxy or similar that could interfere.

Running cargo upgrade -v doesn't provide any more info.

$ cargo --version
cargo 1.71.1 (7f1d04c00 2023-07-29)
$ cargo upgrade --version
cargo-edit-upgrade 0.12.0

For anyone else who finds themselves here:

In order to use cargo-upgrade currently (on a fresh Rust install that has otherwise been using the new default sparse index protocol), it seems that you need to force usage of the git index protocol, and potentially perform an initial fetch to avoid a NotFound error like this.

CARGO_REGISTRIES_CRATES_IO_PROTOCOL=git cargo fetch
CARGO_REGISTRIES_CRATES_IO_PROTOCOL=git cargo upgrade

Maybe it's worth to be added in the README? I spent about half an hour on this 😢

I'm willing to do this if you accept.

cc current maintainer @epage for ideas.

It's a good call. I spent quite a bit of time on it as well.

Please also suggest CARGO_NET_GIT_FETCH_WITH_CLI=true for cargo fetch. The builtin git client is horribly slow (rust-lang/cargo#11014)

Is there a reason this cargo upgrade doesn't simply switch over to sparse registry? That would solve this issue.

CARGO_NET_GIT_FETCH_WITH_CLI=true and CARGO_REGISTRIES_CRATES_IO_PROTOCOL=git doesn't work in my end. It still takes forever to fetch the deltas.

However, this solves my issue rust-lang/cargo#11014 (comment)

cd ~/.cargo/registry/index/github.com-1ecc6299db9ec823
git fetch https://github.com/rust-lang/crates.io-index refs/heads/master:refs/remotes/origin/master

I can put time into this or I can put time into integrating this with cargo. I have opted for the latter.

put time into integrating this with cargo

Seems cool!

I'm still hitting this issue, and forcing CARGO_REGISTRIES_CRATES_IO_PROTOCOL=git cargo fetch takes so long.

Does anyone know of alternative crates that use the sparse registry?
