Re: [Twisted-Python] Trouble with example imap client on unread messages

Quoting Andy Gayton :

* 244 FETCH (FLAGS (\Seen))

The problem I see is here : why does the server had this line ?

The flags changed, and the server is telling you about it, as it should.

The callback for the above fetchSpecific call is receiving:

{ 243 : [['BODY', ['HEADER.FIELDS', ['SUBJECT']], 'Subject: DELIVERY REPORTS ABOUT YOUR E-MAIL\r\n\r\n']], 244 : [['FLAGS', ['\\Seen']]] }

ie, I'm not getting the subject for unread messages.

Well actually it's logical, because Twisted parses result in a dictionnary so you have : res[243] = < subject >, then res[244] = < subject >, but res[244] = < flags > which overrides previous value.

This is bad, RFC-3501 says: A client MUST be prepared to accept any server response at all times. This includes server data that was not requested. Server data SHOULD be recorded, so that the client can reference its recorded copy rather than sending a command to the server to request the data. In the case of certain server data, the data MUST be recorded. so I'd say twisted's IMAP-client is broken. /Anders -- -- Of course I'm crazy, but that doesn't mean I'm wrong.
