Saving TicketGrantingTicket is failing.

[Larry Zhao]

Hi, Guys,

I am using the latest rubycas-server from Github repository. It works very well in development on my machine, but after I deployed on to my staging machine, an Internal Server Error poped up when I perform a log-in.

I tried to debug, and found that the error is raised by tgt.save! from lib/casserver/cas.rb

def generate_ticket_granting_ticket(username, extra_attributes = {})

    # 3.6 (ticket granting cookie/ticket)

    tgt = TicketGrantingTicket.new

    tgt.ticket = "TGC-" + CASServer::Utils.random_string

    tgt.username = username

    tgt.extra_attributes = extra_attributes

    tgt.client_hostname = @env['HTTP_X_FORWARDED_FOR'] || @env['REMOTE_HOST'] || @env['REMOTE_ADDR']

    $LOG.debug tgt.inspect


    tgt.save!

    $LOG.debug("Generated ticket granting ticket '#{tgt.ticket}' for user" +

      " '#{tgt.username}' at '#{tgt.client_hostname}'" +

      (extra_attributes.blank? ? "" : " with extra attributes #{extra_attributes.inspect}"))

    tgt


  end

I changed the code a little bit to print out more information, and refreshed my database, but it's still failing, I don't know how to investigate further. Needed your help.

From casserver.log, the authentication is successful and it stops just before the tgt.inpect

What could be the problem?

I turned on :show_exceptions to true on my staging environment, and got this, what the reason is that?

Finally, I found out that it's because in there's non-ASCII characters in the extra_attributes filed of TicketGrantingTicket, in my case, Chinese, which caused this error when being serialized into YAML I believe.

Just fixed it by adding the following on top of my Gemfile, I am not sure if it's the good solution or not...

if RUBY_VERSION =~ /1.9/

  Encoding.default_external = Encoding::UTF_8

  Encoding.default_internal = Encoding::UTF_8

end

Regards.

Thanks for that Larry. Tyler and I were actually trying to deal with this same issue last week, but taking a different approach. This might help.

I'll work on incorporating this into my existing UTF-madness branch.

[t.pickett66]

Larry, what database and interpreter are you using? I'm trying to reproduce this with tests using the string you supplied and can't seem to get 1.9.3 to gag on it.

The spec I've added is:

describe CASServer::Model::TicketGrantingTicket do

  it "should successfully be able to serialize non-ascii extra attributes" do

    tgt = CASServer::Model::TicketGrantingTicket.new

    tgt.ticket = "test-ticket"

    tgt.username = 'name'

    tgt.extra_attributes = {"name"=>"于浩"}

    tgt.client_hostname = 'host.test'

    tgt.save!

    1.should == 1

  end

end

The only way I can get this error to be thrown is by removing the encoding statement from the top of the spec file and then it fails when parsing the file. I wonder if specifying the encoding of the files is masking the issue. I'll keep poking at it but if you have time please pull from my utf8-madness branch and see if the problem persists without your fix.

Hi, Tyler,

I am using ruby-1.9.3-p194 and mysql. I may have no time to work on this tomorrow, but I will check your branch out on Monday and give you a feedback.

Cheers,

Hi, Tyler, where is this 'utf8-madness' branch? I didn't found it at https://github.com/tpickett66/rubycas-server nor under your github repos https://github.com/tpickett66

Larry,

Sorry for the confusion it was originally filed under my company's account (https://github.com/r2practice/rubycas-server) but has sense been merged into the main master so I removed the branch from that repo.

[Larry Zhao]

Hi, Tyler,

I suppose I should use the master branch from the repo under your company's account to try this UTF-8 thing out. 

I started the application on my local machine, but I encountered the following exception when calling /login :

Is there anything I missed?

Regards.

Larry

Larry,

That's strange. The undefined method on String was added in another series of commits that were merged recently. The extension should be found in casserver/core_ext/string.rb Either it isn't getting required and included in String or it doesn't exist. I'm not sure why either of these would be happening since I'm using the current master for my own testing without incident.

[Larry Zhao]

Hi, Tyler,

Found out that after I add `require 'casserver/core_ext'` this line to `casserver/server` this Sting extension thing is fixed. I could see the login page showing now. 

I got no time for the rest today. I will try it out in the next few days. 

Regards.
