gnunet-mqtt's Issues

Allow UFT8 Topic Strings

The MQTT Spec says the following about topic strings:

Topic name: A UTF-encoded string. This must not contain Topic wildcard ("+", "#") characters.

Multicast Channel Announcement

When a peer is publishing a message it searches for subscribers via GNUNET_REGEX.
When a subscription is found create a new multicast channel
announce it (if there is no existing channel for the topic already) under

    GNUNET_HashCode dht_key_of_accept_state = ... // get via REGEX api
    GNUNET_HashCode dht_key_of_channel;
    GNUNET_CRYPTO_hash(dht_key_of_accept_state, sizeof(struct GNUNET_HashCode), &dht_key_of_channel);

Implement support for retained messages

Enable GNUnet logging

Right now no log output appears. It is unclear if this is because of configuration issues or if the log system is broken/not used correctly.

Fix make check

gnunet-mqtt has the option to run a self test using make check. This however fails with the following message:

Incomplete doc at GNUNET_MQTT_subscribe

It is not documenting all the necessary arguments

Fix test_mqtt_regex_hash

Report

Make Sure Commandline tools are working....

... for the demo

Get the project to build...

...using auto conf & auto make

Let make check use the local version of gnunet-service-mqtt

It always uses the one in /usr/local which means that I can not test my changes unless they are installed first.

I guess there is a way to make it use the local one instead :)

Check Public MQTT API

for stuff like const and all that good jazz

Fix test_mqtt_unsubscribe

Implement support for QoS1 and 2 messages

Announce Subscription anonymously

When a peer subscribes to a regex announce the regex anonymously (using the new REGEX api).
Get the dht keys for accept states for the announced regex.
Check DHT for multicast channel for those accept states, get the channel public key form dht via a key generated like this

    GNUNET_HashCode dht_key_of_accept_state = ... // get via REGEX api
    GNUNET_HashCode dht_key_of_channel;
    GNUNET_CRYPTO_hash(dht_key_of_accept_state, sizeof(struct GNUNET_HashCode), &dht_key_of_channel);

add the channels to a subscription list

Join Multicast channels

Persist channels
join all channels on startup
leave all channels on unsubscribe, disconnect or shutdown
