Hi,

I am updating a system with a variety of spells from the past decade
and am also stumbling over download troubles. One thing is figuring out
sorcery's mirror selection: For xml-twig It tries the configured
PERL_CPAN_URL and then a bunch of others, finally dropping to the
overall default fallback mirror of home.shlrm.org/sourcemage/fallback/.

But I have this in /etc/sorcer/local/url:


sh# cat /etc/sorcery/local/url 
FALLBACK_URL_MIRROR[0]="http://mirror.sobukus.de/src";
     
SOURCEFORGE_URL="${SOURCEFORGE_URL:-http://switch.dl.sourceforge.net/sourceforge}";
       
PERL_CPAN_URL="${PERL_CPAN_URL:-ftp://ftp.fu-berlin.de/unix/languages/perl}";


It worked before that this uses my own server as fallback mirror. Not
this time. I changed sorcery versions in between and am now on stable.
Am I relying on a devel feature?

Oh, apparently. Switching to devel sorcery makes it pick up my mirror.
Can we please port that feature to stable?

Anyhow, what I want to complain about is home.shlrm.org. It says 200 OK
and then delivers a 404 page to wget:

That confuses sorcery as this is a HTML file with "404 Not Found" in
it. Correct behaviour should be that, right?

shell$ wget http://mirror.sobukus.de/XML-Twig-3.46.tar.gzz

On the other hand, it happens not so rarely nowadays that "helpful"
download sites produce a human-readable HTML message when a file is not
found. Perhaps we should summon in a smarter way, checking that we only
got a sorry note and download from a different server.

But at least our own servers should not confuse sorcery, right?


Alrighty then,

Thomas
