It looks like the Mac OS X 10.5.3 upgrade breaks DRb when it’s trying to
open a TCPSocket.
Looking into it now, but be warned:
/opt/local/lib/ruby/1.8/drb/drb.rb:865:in initialize': getaddrinfo: nodename nor servname provided, or not known (SocketError) from /opt/local/lib/ruby/1.8/drb/drb.rb:865:inopen’
from /opt/local/lib/ruby/1.8/drb/drb.rb:865:in `open_server’

I’m running into the same problem too having just upgraded. Is there a
solution?

No solution yet, but it looks like something has changed in some
underlying networking library, as base socket handing methods seem to be
broken:
[kschrader@einstein:~]$ irb
require ‘socket’
=> trueSocket.getaddrinfo(Socket.gethostname, 0, Socket::AF_INET, Socket::SOCK_STREAM, nil, Socket::AI_CANONNAME)
SocketError: getaddrinfo: nodename nor servname provided, or not known
from (irb):2:in `getaddrinfo’

Damn, I need a fix bad – Either that or I’m re-installing my entire OS
X machine to get rid of 10.5.3.
I’ll help anyway I can, but I’m not good with the underlyings.
Please let us know as soon as you find something.
Thanks for the report, we are of course very sorry about that. Ruby
didn’t change in Mac OS X 10.5.3, so we are currently investigating
possible regressions in the underlying frameworks. We will let you
know.
Following Andy’s idea, what about the following as a temporary fix?
Seems to work for DRb servers with a port of 0 (which seems to be the
default). Apparently DRb servers which explicitly bind to a non 0 port
are not affected by this regression.
class DRb::DRbTCPSocket
class << self
alias parse_uri_orig parse_uri
def parse_uri(*args)
ary = parse_uri_orig(*args)
ary[1] = nil if ary[1] == 0
ary
end
end
end

I’ve not done too much Ruby socket programming, but it seems to be that
it doesn’t like 0 as a service number, because it is interpreting it as
the real service 0, instead of the empty service… if you use nil
instead it works fine… you might be able to patch dRb to use that as a
work around.

Laurent,
That seems to work for now. Thanks for looking into it.

Where does this wonderful piece of code go?
I put this just before “Rails::Initializer.run(:set_load_path)” in
config/boot.rb

Incase you get errors and cannot get the hack above, try putting it in
the environment.rb file INSIDE the config block.

Anyone else get errors from inserting this code?
if you place it in the LINE before

which makes sense.
if you place it outside of the Boot Class you get a SystemStackError

Yeah that doesn’t work either.
A) INSIDE config block of environment.rb,
B) Before the “Rails::Initializer.run(:set_load_path)” line in boot.rb.
Neither A or B work.
Any other ideas?

You forgot to require DRb.
Add require ‘drb’ right above the code.
I had the same problems and this fix makes it possible for mongrel to
start and I thought everything was fine.
But, I can’t seem to run any background tasks using backgroundrb.
I get
The error occurred while evaluating nil.object - (NoMethodError)

Line 396 is:

Anyone else having trouble?
Davis K. wrote:

Yes. I’m having problems with backgroundrb too, even with the hack.
I’m running Ruby out of MacPorts and it looks like a lot of others in
this thread are too.
Is this a problem for those running the version of Ruby included with
Mac OS X as well? Looks like Lorgio Jimenez was running into some
problems using Mac OS X’s Ruby.
Does anyone know if/when this is going to be fixed?
I just thought I’d tell people what I ended up doing to solve the
problem so that they might avoid some of the problems I ran into.
I downgraded to 10.5.0 via my leopard install cd using the preserve
perferences option.
I was hoping it’d leave everything the same, just downgrade the system,
so all my filesystems would be intact (/usr/local/src, bin etc etc.)
Wrong assumption. They were scattered all over a folder that was
created called “Previous System”
At first I thought I could piece it all together, but no way!. It was
like a bomb went off and scattered my development environment all over
the place with no discernible logic.
So
I rebuilt my whole environment from scratch - gems, mysql, ruby, rails,
subversion etc etc etc.
Total nightmare.
If you can find a way to patch the problem until apple fixes it - do.

Sure seems like it. Check this out:
% /usr/bin/ruby.orig -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [universal-darwin9.0]
% /usr/bin/ruby.orig -r socket -e “TCPServer.open(‘localhost’, 0)”
-e:1:in initialize': getaddrinfo: nodename nor servname provided, or not known (SocketError) from -e:1:in open’
from -e:1
Does anyone know if/when this is going to be fixed?
Keep in mind that I have almost no experience with socket programming,
but I have submitted a patch for MacPorts under this ticket. Use at
your own peril! It seems to work for me, but your mileage may vary!

I put it in environment.rb outside of the config block and it works
like a champ.
What a drag – why didn’t I hear about this at RailsConf?

Having lots of problems with this bug. Tried some of the fixes suggested
in this thread but with no luck. Any idea when we might be getting a
fix?
Apple fixed the DRb problem in the 10.5.4 update, which was released at
the
end of June.
