As far as I can tell, asyncore/asynchat is all "undocumented internals". Any use of asyncore in anger will use internals; there never was any well-understood API to these modules. Medusa itself (from which asyncore and asynchat were derived) appears to itself break with the changes to asyncore/asynchat in 2.6 (at least it appears to use attributes like "ac_out_buffer" which were removed in 2.6; this is not "Zope's version"; there is no such animal; this is plain old Medusa 0.5.4). Count me in as one who believes that it would be the lesser of two evils to revert to the older (2.5 and prior) asyncore/asynchat implementations in 2.6.2 rather than soldiering on with the 2.6 and 2.6.1 implementation (which almost certainly has fewer, if any, consumers); somebody messed up in 2.6 by making its asyncore/asynchat more forward compatible with 3.0's than backwards compatible with 2.5's and prior; this was just a mistake and keeping old code running should trump any theoretical or puritanical benefit in a dot release. - C _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
