           Summary: Violates a XEP's MUST by trying to register with
                    incomplete information
           Product: Telepathy
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: telepathy-gabble
        AssignedTo: telepathy-bugs at lists.freedesktop.org
        ReportedBy: will.thompson at collabora.co.uk


>From get_reply_cb (I added this a couple of days ago):

  /* FIXME: "The requesting entity MUST provide information for all of the
   *        elements (other than <instructions/>) contained in the IQ result."
   *        What should we do if the IQ contains <email/> or something else
   *        that we can't provide? Currently we just submit the form anyway and
   *        hope for the best.
   */

This seems to have become a practical problem: I just tried to register with
jabber.org and it failed pretty miserably, since it now requires email address
and real name. From LM_DEBUG=net (reformatted for clarity):

--> <iq type="get" id="268488301266">
        <query xmlns="jabber:iq:register"></query>
    </iq>

<-- <iq id='268488301266' type='result'>
        <query xmlns='jabber:iq:register'>
            <name/>
            <email/>
            <instructions>Additional information is needed to
register.</instructions>
            <username/>
            <password/>
        </query>
    </iq>

--> <iq type="set" id="135881693239">
        <query xmlns="jabber:iq:register">
           
<username>snhostnaosntuoesnuoeustnueostnuaoshuoanstuoeastnuoeanshuoestneostno</username>
            <password>snhaoestnuatsheuahtsaauosnauoenthaoenthauonoha</password>
        </query>
    </iq>

<-- <iq id='135881693239' type='result'/>

(Yes, jabber.org says it worked. So maybe it lied to us.)

At this point Gabble fell down a well:

    ** (telepathy-gabble:28074): DEBUG: registration_finished_cb: succeeded
    ** (telepathy-gabble:28074): DEBUG: do_auth: authenticating with username:
snhostnaosntuoesnuoeustnueostnuaoshuoanstuoeastnuoeanshuoestneostno, password:
<hidden>, resource: Telepathy
    ** (telepathy-gabble:28074): DEBUG: gabble_register_dispose: dispose called
    ** (telepathy-gabble:28074): DEBUG: gabble_register_finalize: called with
0x90fc70

and that was it.

Gabble can't supply the extra information, so it MUST fail the registration
process per the XEP. So I guess maybe we need a new Registration interface,
possibly *shock* using vCard fields from ContactInfo! \o/
