not working on os x mavericks ruby 1.9 ? about hostsfile

[sethvargo]

What does your hostsfile look like?

[sgarbesi]

The hostsfile is the stock repo, unmodified.
(version 2.4.3)

Works fine on my 8 other Ubuntu boxes, only seems to be a problem on the Mac dev box.

[sethvargo]

@sgarbesi okay... could you please answer my question? What does it contain? I don't have access to a "stock repo, unmodified". I need a real test case

[sgarbesi]

@sethvargo Is this what you're looking for?

hostsfile

knife cookbook site install hostsfile

test cookbook:

knife cookbook create test;

test/metadata.rb:
echo "depends 'hostsfile'" >> test/metdata.rb

test/recipes/default.rb (same code that I previously pasted in my first comment):

# Uniquely enforce our localhost record.
hostsfile_entry '127.0.0.1' do
    hostname 'x-dx-dev-01.dolox.com'
    aliases ['x-dx-dev-01', 'dev.dolox.com', 'localhost']
    comment 'Maintained by Chef'
    action :create
end

[sethvargo]

@sgarbesi no, I literally need to see the contents of /etc/hosts:

$ cat /etc/hosts

[sgarbesi]

@sethvargo I can't post that here, it contains sensitive data.

There are several 127.0.0.1 entries; possibly that is the problem?

Is there anything in particular you're looking for that maybe I can see if it's relevant?

[sgarbesi]

@sethvargo

/etc/hosts (I stripped it down to just this and still get the same error).

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       x-dx-dev-01.dolox.com x-dx-dev-01 localhost
255.255.255.255 broadcasthost
::1             localhost
fe80::1%lo0     localhost

[sethvargo]

@sgarbesi then you're previous statement that it's a "stock" file is incorrect. I can't help you debug without that information. Basically you either have an entry with an invalid address or an entry without an address, thus making the line invalid.

[sgarbesi]

@sethvargo I posted the file stripped down with the test case and it doesn't work?

In other words I changed my hosts file to contain nothing but my previous post and ran the test and received the same error. The hosts file is valid.

[sethvargo]

The error is happening on this line. That means one of the IP addresses in your hostsfile is not valid. It's either blank or malformed.

[1] pry(main)> require 'ipaddr'
=> true
[2] pry(main)> IPAddr.new('127.0.0.1')
=> #<IPAddr: IPv4:127.0.0.1/255.255.255.255>
[3] pry(main)> IPAddr.new('255.255.255.255')
=> #<IPAddr: IPv4:255.255.255.255/255.255.255.255>
[4] pry(main)> IPAddr.new('::1')
=> #<IPAddr: IPv6:0000:0000:0000:0000:0000:0000:0000:0001/ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff>
[5] pry(main)> IPAddr.new('fe80::1%lo0')
IPAddr::InvalidAddressError: invalid address
from /Users/sethvargo/.rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/ipaddr.rb:559:in `in6_addr'

So Ruby thinks fe80::1%lo0 isn't a valid IPv6 address. There's not much I can do here - IPAddr is a core Ruby class. So if it's blowing up, that address either isn't valid or the Ruby core has a bug.

[sethvargo]

Actually, there's a test in MRI explicitly testing that an address of that format DOES raise an error: https://github.com/ruby/ruby/blob/trunk/lib/ipaddr.rb#L738

[sgarbesi]

@sethvargo Okay.

This is the stock /etc/hosts file that Apple ships with OS X Mavericks.

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1   localhost
255.255.255.255 broadcasthost
::1             localhost 
fe80::1%lo0 localhost

[sethvargo]

Right. And, according to Ruby, fe80::1%lo0 is not a valid IPv6 address.

[sgarbesi]

@sethvargo Alright then; not sure if it's worth posting in the wiki/readme or not.

Removing fe80::1%lo0 localhost allows it to run without error.

Thanks for the help! Appreciate it.

[sethvargo]

@sgarbesi well I need to figure out what to do. This might actually be a bug in OSX Mavericks (since all indications say that is NOT a valid IPv6 address).

[sethvargo]

Sigh. See also: http://johncblandii.com/2011/07/osx-lion-gotcha-etchosts-file.html

[sethvargo]

Blarg. https://bugs.ruby-lang.org/issues/8464

[sgarbesi]

@sethvargo Ouch :/

Personal opinion: I would post it in the README/Wiki and call it a day.

[sethvargo]

v2.4.4

[sgarbesi]

Tested and works fine on v2.4.4.

Thanks again @sethvargo !

[sethvargo]

Yup
