Rust - invalid gzip header

[rel_0477]

Previously, I reported a bug where publishing Rust packages wouldn't compress properly and thus wouldn't be able to be viewed online or pulled. Re: Rust Crates are uploaded with an incorrect compression method

I am experiencing a new error when attempting to pull a Rust package from ProGet.

Error:

Caused by:
  failed to iterate over archive

Caused by:
  invalid gzip header

I am able to view the package fine on the web interface, which is unique to the previous error.

Hi @rel_0477 ,

Sounds like this is a pretty specific edge case. Can you provide a reproduction case so we can take a look?

Thanks,

I reproduced it in the following:

cargo new reproduction --lib
cd reproduction
cargo publish --index sparse+<proget url> --token <token> --allow-dirty
cd ..
cargo new pull
cd pull
nano Config.toml

My Config.toml:

[package]
name = "pull"
version = "0.1.0"
edition = "2024"
publish = ["crates-io"]

[dependencies]
reproduction = {version = "0.1.0", registry = "crate"}

cargo build

Result:

cargo build
    Updating `crate` index
     Locking 1 package to latest Rust 1.87.0 compatible version

error: failed to unpack package `reproduction v0.1.0 (registry `crate`)`

Hi @rel_0477,

Thanks for sending over the reproduction case. I was able to identify the issue, PG-2993, and have it ready to go in the next maintenance release of ProGet.

Thanks,
