Exception thrown when fetching freedb info #496

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
1) Please describe the steps to reproduce the situation:
a. run rubyripper_cli.rb version 0.6.1
b. when fetching freedb info you get:

    Exception thrown: undefined method `[]' for nil:NilClass
    Couldn't connect to freedb server. Network down?

3) What version of rubyripper are you using? On what operating system? The gtk2 
of commandline interface?
On Linux using commandline version 0.6.1, same thing happens with gtk2 version.

4) Is this not already fixed with the latest & greatest code? See for
instructions the Source tab above.
Get error trying to run version from git.

Same issue here with the rubyripper HEAD and Ruby 1.9.3 - this is the 
stacktrace:

With Ruby 1.8.7, the error is slightly different:

I don't know if I did this right, as I have never used and/or debugged a ruby 
program before.  I ran ruby -rdebug and hit c until I got this:

This is due to an update in the Ruby Net::HTTP module. I've updated the master 
and the stable branch in git.

When I run git stable I now get this error:

cddb_query return code = 500. Return code not supported.

GoogleCodeExporter commented 9 years ago 
I've added two debug statements. Please try again, when started from the 
terminal, and set the debug option on (other settings). Notice, that I cannot 
reproduce this behaviour. A 500 error should only occur in case of invalid 
queries.

I ran ruby -d and got:

Fetching freedb info...
cddb query 1 = 
/~cddb/cddb.cgi?cmd=cddb+query+960c670a+10+150+18500+42065+67350+88987+112212+13

Exception `Errno::EAGAIN' at /usr/lib/ruby/1.9.1/net/protocol.rb:141 - Resource 
temporarily unavailable - read would block
cddb_query return code = 500. Return code not supported.

I'm using ruby 1.9.3-p0 if that helps.

The solution is simple: don't leave the username + hostname blank in your 
configuration. It goes wrong here: &hello=++rubyripper+0.6.1.

This should be something like &hello=anonymous+my_secret.com+rubyripper+0.6.1

Ah, sorry I must have deleted it.

I've 'fixed' this in the master branch:

filling in user and host does NOT help

[carnager@freebox ~]$ egrep -i 'freedb|username|host' 
.config/rubyripper/settings 
site=http://freedb.freedb.org:80
username=anonymous
hostname=bla.blub.de
freedb=true

cddb_query return code = <!D. Return code not supported.

Oh and master branch doesnt work either...

I get the same nilClass error.  Rubyripper uses a proxy.  It SUCCESSFULLY 
receives the reply from squid (HTTP 200):
210 Found exact matches, list follows (until terminating `.')
data 12345 foo
rock 12345 bar
.

But STILL rubyripper says:
Couldn't connect to freedb server.  Network down?

I have ruby 1.9.3.286-18.fc17
