update URL for Mach's Zig mirror #599

emidoots commented 2026年03月27日 03:29:36 +01:00

Previously, Mach's Zig mirror pkg.machengine.org was written in Go as part of a larger tool that did unrelated things.

We rewrote Mach's mirror in Zig, making a tailor-fit pkgmirror service for just this purpose so that others can host Zig mirrors more easily.

pkg.machengine.org will remain online, but redirects to https://pkg.hexops.org

FYI: pkg.machengine.org is now just a redirect to pkg.hexops.org which has been running nicely :)

Thank you! FYI, there was one failure in the CI for this mirror, but it may well have been a bug in std.http.Client rather than in your mirror. Still, in case you are able to look into it at all, it was fetching zig-x86_64-netbsd-0.16.0-dev.3006+94355f192.tar.xz, and had this error trace:

No worries if you don't have any way to look into that, I'd probably be willing to put money on it being our fault :P

@mlugg took a quick look, and yeah am suspecting a bug in std.http.Client somehow - at least Firefox can fetch it and it extracts fine:

https://pkg.hexops.org/zig/zig-x86_64-netbsd-0.16.0-dev.3006+94355f192.tar.xz

Also checked logs on the server but nothing relevant. Definitely let me know if you continue seeing anything like this.
