In order for T40: Set up redirects from old bugzilla.wikimedia.org URLs to work, first bugzilla.wikimedia.org needs to point to phabricator.wikimedia.org.
According to @Dzahn, in production things aren't as simple as they were in our wmflabs test:
<mutante> i can't _just_ redirect the DNS
<mutante> because the server phab runs on, doesn't have a public address
<mutante> it is all proxied behind varnish cluster
probably needs these instead:
https://gerrit.wikimedia.org/r/#/c/172469/
https://gerrit.wikimedia.org/r/#/c/172471/
see comments
note how this switches ALL of the following:
bugs.wikimedia.org
bugzilla.wikimedia.org
bug-attachment.wikimedia.org
the script from T40 would have to be ready to handle them all, i think it may not. uses just "phabzilla.wmflabs.org"?
if ($_SERVER['HTTP_HOST'] == 'phabzilla.wmflabs.org') {
$_SERVER['HTTP_HOST'] = 'bugs.wikimedia.org';
the change that applies the script on production phab server: merged , has been deployed on iridum
the change that changes Varnish config to make request for Bugzilla hosts go to iridium as backend: merged, has been deployed on cp1043/cp1044
the DNS change: NOT MERGED until actual migration moment
but this means you can now test by hacking your local /etc/hosts file and pointing to misc-web
if you switch bugzilla.wikimedia.org over to misc-web-lb.eqiad.wikimedia.org in your hosts file, the redirects should work
this has happened here:
https://gerrit.wikimedia.org/r/#/c/172469/
https://gerrit.wikimedia.org/r/#/c/175133/
pointing it to misc-web meant pointing it to phabricator which is behind that
