'Channel' improperly parsed in Events

Reported by jsgoecke | December 19th, 2008 @ 11:08 AM

I am storing off Events to a CouchDB instance and noticed the Channel arrives in the hash as follows:

"Channel: IAX2/127.0.0.1"=>"4569-9904"

I believe it should be:

"Channel"=> "IAX2/127.0.0.1/4569-9904"

More details here, and the CouchDB document attached:

    I added some lexer specs to try to reproduce this issue but they pass. For some reason I can't reproduce this. Are you sure this is happening in Adhearsion-land and not CouchDB land? I don't see how the lexer could parse that improperly...

    This gist:

    Is simply this in events.rb:

    So, before it even gets to CouchDB I see it mangled (and in fact when not using CouchDB at all and just showing the event). Just did a git pull on the latest ahn master and still able to produce it:

    For the record, this doesn't seem to be an issue with SIP:

    
     INFO ahn: #<Adhearsion::VoIP::Asterisk::Manager::ManagerInterfaceEvent:0x114278c @headers={"CallerIDNum"=>"jicksta", "Channel"=>"SIP/0.0.0.0-007f4f30", "Uniqueid"=>"asterisk-5881-1230185859.0", "State"=>"Down", "Privilege"=>"call,all", "CallerIDName"=>"Jay Phillips"}, @name="Newchannel">
    

    Testing with IAX next...

    It seems IAX is parsed properly when using an IAX softphone. I need to test with an IAX trunk (to get the IAX2/trunk/exten format) still...

    I was just dialing back to localhost with an IAX2 trunk, did not need a 'real' one for testing.

    This error also occurs with the appdata event if it contains an AGI attribute, as follows:

    WARN event_logger: ["AppData: agi", "//localhost"]

    As you may see, it is not parsing correctly. As it should look like this:

    ["AppData", "agi://localhost"]

    I wrote a method that may fix this by putting the data back together properly:

    def fix_event_parsing(header)

    first_field = header[0].split(' ')
    header[0] = first_field[0].gsub!(':','')
    header[1] = first_field[1] + ":" + header[1]
    return header
    
    

    end

    Can't really use Ruby string manipulation to fix this bug. This is a bug in the Ragel lexer generator.

    Hello, I have a variable in asterisk that store a url as well as other parameters seperated by coma eg

    Set(eventstring=${Number}','${urlstring})

    where urlstring=http://xx.xx.xx.xx/eventmanger

    but in my ami event in adhearsion it replaces ':' with "=>" ideas why?

    INFO ami: #<Adhearsion::VoIP::Asterisk::Manager::ManagerInterfaceEvent: 0xb787b2a4 @name="Newexten", @headers={"AppData: 4504,86,2,2,SIP/ 192.168.x.x-081914c0,http"=>"//192.168.x.x/EventManager", "Channel"=>"SIP/192.168.x.x-081914c0", "Context"=>"cb_emergency_temp", "Uniqueid"=>"1236958200.106", "Application"=>"NoOp", "Privilege"=>"call,all", "Priority"=>"7", "Extension"=>"s"}>

    thanks David L

    Okay, this should be fixed now in master.
