Re: Anubis challenge on texlive.info pretest mirror breaks TeX Live Utility

    Looking for available updates on https://texlive.info/tlpretest/ with
    TeX Live Utility (on the Mac), an error is obtained:

As you suggested, I think it would be easy enough to whitelist TLU's
user-agent string on texlive.info.  It would be nicer if there was
something more specific than "AppleWebKit" to whitelist, though.  In
fact, Adam, if you used a user-agent string starting with "texlive/",
looks to me like it would be let through.

    Unclear what could be parsed. "finish load" vs "fail load"?

Yes. Those messages are output specifically by --machine-readable in
order to be parsed, as far as I can see. For example:

  if (!defined($texlive_release)) {
    info("fail load $location\n") if ($::machinereadable);
    ...

Then the subsequent lines are the error messages, evidently.

Regarding anubis, tlmgr doesn't do anything specific to deal with it.
If other mirrors started using anubis (or whatever), it would fail. -k
