embedded-hal-nb v1.0.0-alpha.2 missing from index.

[Dirbaio]

Problem

embedded-hal-nb v1.0.0-alpha.2 was released yesterday, however trying to use it as a dependency fails, as if it wasn't there.

Steps

[dirbaio@mars ~]$ cargo new repro
cd     Created binary (application) `repro` package
[dirbaio@mars ~]$ cd repro/
[dirbaio@mars repro]$ echo 'embedded-hal-nb = "=1.0.0-alpha.2"' >> Cargo.toml 
[dirbaio@mars repro]$ cargo build
    Updating crates.io index
error: failed to select a version for the requirement `embedded-hal-nb = "=1.0.0-alpha.2"`
candidate versions found which didn't match: 0.0.0
location searched: crates.io index
required by package `repro v0.1.0 (/home/dirbaio/repro)`
perhaps a crate was updated and forgotten to be re-vendored?

Possible Solution(s)

Looking with CARGO_LOG=trace, it seems it's downloading this https://index.crates.io/em/be/embedded-hal-nb, and indeed v1.0.0-alpha.2 is missing.

It seems to be an issue of the new sparse protocol only. Forcing using the old one works: CARGO_REGISTRIES_CRATES_IO_PROTOCOL=git cargo build

Thanks for the report! I have raised this with our infrastructure people.

some of my gh workers have the same problem, but on my local dev environment i don't have an issue. Some output from my local env:

wget -q -O - https://index.crates.io/em/be/embedded-hal-nb

note that this does not have the 1.0.0-alpha.2 version in it. But i can do the follwing and get an correct 304 ->
curl -I --header 'If-Modified-Since: Wed, 06 Apr 2023 10:10:24 GMT' https://index.crates.io/em/be/em bedded-hal-nb

and if i want to download it manually with curl -I -L https://crates.io/api/v1/crates/embedded-hal-nb/1.0.0-alpha.2/download --output " file.crates" it works
this is the the header response :

i was got is that problem too

[Dirbaio]

I yanked version 0.0.0, it seems it caused that index file to be regenerated, and the issue is gone now.

[weihanglo]

The issue is discussed here on Zulip.

@ehuss @Turbo87 should we transfer this to rust-lang/crates.io repository?

[Turbo87]

@weihanglo yes, please! 👍

[Turbo87]

as a short term fix, we ran a complete sync from the git index to the sparse index. https://index.crates.io/em/be/embedded-hal-nb for me now shows the missing version.

the cause of the issue is described in the Zulip thread that was linked above and still needs a more long-term fix though, so I'll keep this issue open for now.
