Cargo-edit: Clean updating the crates.io index sets 'refs/remotes/origin/' to HEAD insted of master

[meltinglava]

Running any cargo add {crate} would fail with:

Command failed due to unhandled error: reference 'refs/remotes/origin/master' not found; class=Reference (4); code=NotFound (-3)

After some debugging i found that the cargo index had its 'refs/remotes/origin' set to HEAD instead of master. I tried rebuilding the index by running rm -rf ~/.cargo/registry/index/github.com-*/ and then cargo add <any dependency>. This updated the index, however now refs/remotes/origin/ still contains HEAD insted of master.

Found the line in that failed in this lib to be: https://github.com/killercup/cargo-edit/blob/034f6efc6c9c86ce07a0ad01cfbb55198397e1ec/src/fetch.rs#L271
Confirmed that running mv HEAD master temporarily fixed the problem.

Thanks for the report. Hmm, this is strange, I can't reproduce the issue. Have you tried removing the index and rebuilding it with cargo check instead of cargo add?
This is what I got after that:

❯ tree ~/.cargo/registry/index/github.com-1ecc6299db9ec823/.git/refs/remotes/origin
~/.cargo/registry/index/github.com-1ecc6299db9ec823/.git/refs/remotes/origin
└── master

Updating the index is done here:

Did indeed fail on cargo check as well. Thow I narrowed down the issue. This works as intended on Stable, but not on nightly.

I'm facing same issue on nightly.

-bash-5.0$ cargo add clap
Command failed due to unhandled error: reference 'refs/remotes/origin/master' not found; class=Reference (4); code=NotFound (-3)

can I revert back cargo-edit to older version as temporary workaround?

[meltinglava]

@kavirajk no. Temporarly solution is to rename the file in ~/.cargo/registry/index/github.com-*/.git/refs/remotes/origincalled HEAD to master

[meltinglava]

Have thought about some fixes. One would be to allow cargo add to use any of the origins. Think we always expects this to have 1 file in that directory.

+1, Same problem with OP, hope for the new version
