Bug#1057431: fakeupstream.cgi: add support for static.rust-lang.org
Package: qa.debian.org
Severity: wishlist
Tags: patch
X-Debbugs-Cc: zixing.liu@canonical.com
Hi Debian QA Team,
I would like to see a fakeupstream service implemented for
https://static.rust-lang.org/dist so that the debian/watch file inside the
rustc package could be simplified and actually useful for checking new
releases.
Attached below is a patch that I proposed to add the said functionality.
You can find the same patch at:
https://salsa.debian.org/qa/qa/-/merge_requests/48
if you prefer using Debian Salsa to merge the patch/merge request.
Thanks,
Zixing
