Don't follow redirects in fetch phase

[giorgio_v@…]

Here’s the scenario: I’m trying to fetch the latest postgresql update, but the first master site url (​http://ftp8.us.postgresql.org/postgresql/) does not resolve. Since I’m using OpenDNS, the original request is redirected to a custom web page and that’s what curl downloads to the disk. Obviously, the checksum fails.

Maybe it could be sensibile to avoid redirects.

Following redirects is also useful (eg, when using sourceforge's downloads.sourceforge.net redirector); DNS should be returning an NXDOMAIN for that hostname, but OpenDNS appears to point to hit-nxdomain.opendns.com instead.

OpenDNS is cool, but breaks normal DNS behavior unless you configure it to not do it.

hit-nxdomain.opendns.com is returned instead of NXDOMAIN so that they can do the typo correction.

I don't think MacPorts should do anything special to help OpenDNS users.

Right. I tried OpenDNS for about 5 minutes until I discovered that it was broken by design in this way.

Replying to giorgio_v@mac.com:

I agree. I think it’s fair to close this ticket.

On the other hand, it could be useful to try next mirrored site if the checksum fails.
