BC in fw3 should be restored now.

Changes have been made in CVS for this ticket:

http://cvs.horde.org/diff.php/framework/MIME/Attic/MIME.php?rt=horde&r1=1.139.4.46&r2=1.139.4.47&ty=u
http://cvs.horde.org/diff.php/horde/docs/CHANGES?rt=horde&r1=1.515.2.498&r2=1.515.2.499&ty=u

Another related issue is that the class variable 'rfc822_filter' has 
been removed from MIME.php as well.  This needs to be added back for 
BC reasons, as it is also used (at least) in ContactAutoCompleter.php

Right - and we can't change it now because that'll just create more BC 
problems with older Horde versions.

That sounds reasonable, though I still have a nagging voice in my head 
about client code calling a private method. I guess since FW_3 is 
really only being maintained for bugs at this point though, I guess 
there's not much worth in adding a public method for any possible 
future FW_3 releases as well.

Continuing my piecemeal analysis, in FW3, the method is still private, 
and called _rfc2822Encode. I *think* what we should do is:



- change the calls in the HEAD apps to use the public rfc2822Encode 
function and new 2nd parameter



- re-add the original _rfc822Encode function to MIME.php in FW3 for 
backwards compatibility with old code.



Any objections or better ideas?

... and it also affects Whups 1.0.

Following the changelog, this is a BC break for Kronolith with Horde 3.3+

The private method MIME::_rfc822Encode() is called directly from 
kronolith's ContacatAutoCompleter.php file.  That method was renamed 
to _rfc2822Encode() and then made public (renamed to rfc2822Encode()) 
in MIME.php



The function signature has also changed, and now no longer takes a 
'filter' argument, but a 'type' argument in it's place.



This is a sort-of BC break in that the function was changed in MIME, 
but kronolith should not have been calling a private method on MIME 
directly...
