error: unable to unpack tarball to temporary directory: TarHeader

[andrewrk]

Zig Version

0.12.0-dev.3644+05d975576

Steps to Reproduce and Observed Behavior

andy@bark> zig fetch https://www.openssl.org/source/openssl-3.3.0.tar.gz
error: unable to unpack tarball to temporary directory: TarHeader

Appears to be a problem with std lib http client, since it works fine when using wget to download the resource.

Expected Behavior

The same result that I get when fetching the package with wget instead of zig:

andy@bark ~/tmp> zig fetch openssl-3.3.0.tar.gz

Looks like the web server is using incorrect HTTP headers. The content-type should be instead application/gzip, application/x-gzip, or application/tar+gzip, or it should use transfer-compression: gzip.

Or they could just omit the content-type header, then the file extension would be used.

So, Zig's behavior is correct here.

Fixed downstream.
