Hi wonderful Bazel folks,
I--like probably everyone else--make heavy use of the (super handy) http repository rules.
While using them, I'd noticed that the docs for the URL attributes they have in common had started drifting. For example, http_file's URLs array doc was mostly same as http_archive's, except that it forgot to specify that the URLs were tried in the order they were specified. jar_file's were much less complete. Similarly, only http_file was missing the URL parameter, which seems a shame, since probably most people only want to supply one authoritative source most of the time. When I looked at the code, it became clear that this was because the implementations were copy-pasted, and being updated separately.
So I spent a few minutes cleaning things up and making these commonly used features a little more consistent, fixing the issues above. Hopefully that's welcome.
I'd love your thoughtful consideration and review!
Thanks, wonderful Bazel folks, for all you do!
Cheers,
Chris
