426532 - Implement COUNTER iMIP method

Status: NEW

(Calendar :: E-mail based Scheduling (iTIP/iMIP), defect)

Description

[Andy Cowling]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.8.1.12) Gecko/20080201 Firefox/2.0.0.12
Build Identifier: 30 March 2008

If a Domino user is invited to a meeting, and they accept the invitation, but later try to "counter" the meeting forcing a change in its scheduling, Lightning does not recognize the email received. The subject starts "Countered:" 

Also, I received a meeting update with a subject starting "Angenommen:" from a Domino user, which was also not recognized by Lightning.



Reproducible: Always

Steps to Reproduce:
1. Invite a Notes user to a meeting
2. The Notes user accepts the invitation
3. This acceptance mail is processed by Lightning
4. The Notes user then takes subsequent action on this event, such as to try to move it

Actual Results:  
When the resulting email is opened in Thunderbird, Lightning reports "This message contains an event that this version of Lightning cannot process"


Note that this mail was received because a meeting participant was off sick and unable to attend the meeting as originally agreed to. His secretary updated his calendar to reflect this, and I got the email.

Below is the ics event attachment that throws the above error message:

For testing purposes it might be more useful to export the entire email message from Thunderbird and attach it here.

I'd like you to check the Error Console for related error messages and copy+paste them here.

Comment 2

[Andy Cowling]

Attachment: A "COUNTER" imip email, currently not recognized by lightning

As requested by QA, a sample email.

Comment 3

[Andy Cowling]

The "Countered:" email is atteched.

When this email is opened, the Error Console reports:

Unknown imipMethod: COUNTER
chrome://lightning/content/imip-bar.js (line 196)

(The "Angenommen:" email is now recognized by the lated nightly build of
Lightning (2nd April), therefore this part of the bug report should be
considered fixed.)

I'm sure we had a bug regarding COUNTER, but I couldn't find one. This of course needs to be implemented, it would be great if more itip/imip developers step up :-)

Comment 8

[Philipp Kewisch [:Fallen][📱📆]]

Just as with delegation, initial patches still need some bugfixes, but they look very promising!

The code is at http://www.google-melange.com/gsoc/project/google/gsoc2012/cikey/5001

Comment 12

[Paul Boddie]

Did the above patches get accepted or duplicated anywhere before they were lost from the Internet?
