Bug

What happened:

cargo update fails to find deltalake when using git to specify cargo dependency.

What you expected to happen:

cargo update to succeed

How to reproduce it:

# Cargo.toml
[dependencies]
deltalake = { git = "https://github.com/delta-io/delta-rs.git", tag = "rust-v0.14.0", features = [
    "s3",
    "parquet",
    "arrow",
    "datafusion",
] }

$ rustup install 1.70.0
$ cargo +1.70.0 update
    Updating crates.io index
    Updating git repository `https://github.com/delta-io/delta-rs.git`
error: no matching package named `deltalake` found
location searched: https://github.com/delta-io/delta-rs.git?tag=rust-v0.14.0

$ rustup install 1.71.0
$ cargo +1.71.0 update
    Updating crates.io index
    Updating git repository `https://github.com/delta-io/delta-rs.git`

More details:

Using crates.io format deltalake = { version = "0.14.0" } works fine.

Could potentially be related to #1572 ? There were some cargo workspace related changes in cargo, https://github.com/rust-lang/cargo/blob/master/CHANGELOG.md#cargo-171-2023-07-13

Fails for 1.69.0 as well.

Works OK for rust 1.70 and git tag rust-v0.13.0. Looks more and more likely its due to the workspace changes :(

Does this fail in the same way when you use a branch rather than the tag reference?

[cmackenzie1]

Yeah, I tried pointing it at my fork but got the same result. It seems any git style pointer fails rust<=1.70 for v0.14

[rtyler]

According to one of the fine folks over the in the cargo project, this is more likely to be the addition of the line-tables-only option, which I'm hopeful we can make apply only on newer Cargo versions

[rtyler]

Going to close t his out, it's kinda annoying but we should encourage people to use newer cargoes since the upstream issue (in cargo somewhere) is not likely going to be fixed soon
