Hello Mark,
While I was coding for my project, using java-gmail-imap, I came across an
issue which, in my opinion, is important.
The issue can be easily reproduced as I explain below:
1. Fetch x-gm-labels for an email.
2. Change this email's labels using some other client (the gmail web client is,
of course, the obvious way)
3. Re-fetch x-gm-labels for the email.
4. No changes appear to have happened to the email's labels.
I traced this error and I discovered that actually no FETCH command is sent to
the gmail server in step 3.
This happens because FetchProfileCondition.test(IMAPMessage m) called from
Utility.toMessageSet() during the execution of IMAPMessage.fetch returns false.
This actually happens because the condition in the 'if' below...
1035 if (needXGmLabels && m.getGoogleMessageLabels() == null)
1036 return true;
... is always false for any message in the messageCache for which we have
already fetched x-gm-labels.
A simple solution is to remove the m.getGoogleMessageLabels() == null
condition. By doing this, everything works fine.
My opinion is that because x-gm-labels is an attribute that COULD change by
another client during a session (unlike headers, envelope, size, UID,
x-gm-msgid etc.) the m.getGoogleMessageLabels() == null condition should be
removed.
I'm looking forward to hearing your opinion on this.
Best wishes,
Stefanos
