this change spreads the concept of "dirty" from resources to subscriptions. this allows queuing up notifications in case not all of them can be transmitted at the same time (which can happen due to constraints in pdu or node space). when a dirty resource's notifications can not be sent, the resource is marked as partiallydirty, and on the subscriptions that could not be sent out, the dirty flag is set. they get cleared later when coap_notify_observers gets run again, as it not only looks for dirty, but also for partiallydirty resources. note that there is currently no facility that prevents that all the nodes get assigned to the send queue, leaving no room for receiving packages (which happens in mass notifications, blocks all incoming packages and is only resolved by the transmissions timing out). my current test setup always leaves at least one node free for reception by over-allocating and freeing a node on sending.
libcoap: A C implementation of IETF Core Application protocol Copyright (C) 2010--2013 by Olaf Bergmann <bergmann@tzi.org> ABOUT LIBCOAP libcoap is a C implementation of a lightweight application-protocol for devices that are constrained their resources such as computing power, RF range, memory, bandwith, or network packet sizes. This protocol, CoAP, is developed in the IETF working group "Constrained RESTful Environments (core)", see <http://6lowapp.net>.
