[clo-devel] Migration status [2011-05-06]

[Erik Huelsmann]

Hi all,


To follow up on my earlier mail from last weekend:

>  * set up Apache virtual hosts for common-lisp.net,
> lists.common-lisp.net, trac.common-lisp.net (others?)

I've set up two virtual hosts in the web server: lists.cl-net and
trac.cl-net (the latter has an alias for trac.new.common-lisp.net for
as long as it's not the main trac server yet).

The Trac webserver configuration has been ported from Apache1.3 to
Apache2.2, which should take us another 15 years to require updating
again :-)

This has happened now, including authentication setup. If people could
test the new setup is stable again, I'd like to switch trac.cl-net to
this new service.

Raymond, this is where you could do some testing: I've converted the
'oct' trac.ini to support git. There were other projects you wanted to
use with git support. It'd be great if you could test those on the new
machine.

I'm planning to execute the steps above (migrating the MTA) on friday
night, if feedback on Trac is good enough (or none). If there's any
reason not to proceed, please let me know before Friday 18:00 CEST.


Bye,
