This patch removes the need for the RPC Server from aprsd.
APRSD Now saves it's stats to a pickled file on disk in the
aprsd.conf configured save_location. The web admin UI
will depickle that file to fetch the stats. The aprsd server
will periodically pickle and save the stats to disk.
The Logmonitor will not do a url post to the web admin ui
to send it the latest log entries.
Updated the healthcheck app to use the pickled stats file
and the fetch-stats command to make a url request to the running
admin ui to fetch the stats of the remote aprsd server.
This does some cleanup with the stats collector and
usage of the stats. The patch adds a new optional
param to the collector's collect() method to tell
the object to provide serializable stats. This is
used for the webchat app that sends stats to the
browser.
This patch implements a new stats collector paradigm
which uses the typing Protocol. Any object that wants to
supply stats to the collector has to implement the
aprsd.stats.collector.StatsProducer protocol, which at the
current time is implementing a stats() method on the object.
Then register the stats singleton producer with the collector by
calling collector.Collector().register_producer()
This only works if the stats producer object is a singleton.
This adds a layer between the client object and the
actual client instance, so we can reset the actual
client object instance upon failure of connection.
refactored all logging of packets.
Packet class now doesn't do logging.
the format of the packet log now lives on a single line with
colors.
Created a new packet property called human_info, which
creates a string for the payload of each packet type
in a human readable format.
TODO: need to create a config option to allow showing the
older style of multiline logs for packets.
This patch adds the new packet_dump_timeout config option, defaulting to
60 seconds. If the same packet matching the from, to, msgNo is RX'd
within that timeout the packet is considered a dupe and will be
dropped. Ack packets are not subject to dupe checking.
This patch rewrites the packet_list internally to be a dictionary
instead of a list for very fast lookups. This was needed to test for
duplicate packets already in the list.
This patch drops packets that have the same data and are < 60 seconds
in age from the last time we got the packet. On RF based clients
we can get dupes!!
Sometimes over KISS clients (RF), we can get duplicate packets
due to having many digipeters in range of the TNC that aprsd is
connected to. We will now filter out any dupe packets that aprsd
is still in the process of doing it's 3 acks.
This patch adjusts the backoff mechanism for aprs client
reconnect to a max backoff sleep of 5 seconds. This prevents
an exponential backoff when connection retrying.
This patch adds basic ratelimiting to sending out AckPackets
and non AckPackets. This provides a basic way to prevent
aprsd from sending out packets as fast as possible, which isn't
great for a bandwidth limited network.
This patch also adds some keepalive checks to all threads in the
threadslist as well as the network client objects (apris, kiss)
This patch is the initial conversion of the custom config
and config file yaml format to oslo_config's configuration mechanism.
The resulting config format is now an ini type file.
The default location is ~/.config/aprsd/aprsd.conf
This is a backwards incompatible change. You will have to rebuild
the config file and edit it.
Also any aprsd plugins can now define config options in code and
add an setup.cfg entry_point definition
oslo_config.opts =
foo.conf = foo.conf:list_opts
This patch decouples sending a message from the internals of
the Packet classes. This allows the rest of the code to use
Packet objects as type hints in methods to enforce Packets
in the plugins.
The send method was moved to a single place in the threads.tx.send()
This patch updates both the webchat and listen commands
to be able to use the new queue based packet RX processing.
APRSD used to start a thread for every packet received, now
packets are pushed into a queue for processing by other threads
already running.
This patch cleans up the Packet class attributes used to
keep track of how many times packets have been sent and
the last time they were sent. This is used by the PacketTracker
and the tx threads for transmitting packets
The messaging.py now is nothing but a shell that
contains a link to packets.NULL_MESSAGE to help maintain
some backwards compatibility with plugins.
Packets dataclass has fully replaced messaging objects.
This patch reworks all the packet processing to use the new
Packets objects. Nuked all of the messaging classes.
backwards incompatible changes
all messaging.py classes are now gone and replaced by
packets.py classes
This patch refactors the rx threads a bit to reuse some code
responsible for processing acks when packets are received.
This also eliminates a custom thread in the webchat command for
processing received packets now that there is common code in the base
classes.
This patch fixes an issue where aprsd was deciding if it was
supposed to process a packet destined for itself or not. It was
making a case sensitive comparison. This patch makes that comparison
case insensitive for the callsign itself.
This patch changes how aprsd identifies itself when connected to
any client, which is not relying on the login for each client.
There are 3 supported clients currently
aprsis,
tcpkiss
serialkiss.
Each client has their own potential login/callsign to connect
to the remote. This patch tells aprsd to use the new config option
aprsd.callsign as a means to identify itself. It will accept
packets as <aprsd.callsign> and reply as <aprsd.callsign> regardless
of which client object is being used to connect to the remote.
Note: this breaks backwards compatibility. This patch now requires
the new config option
aprsd:
callsign: <callsign>
This patch creates a threads directory and separates out
the contents of threads.py into separate files in the
threads directory to make it easier to find and maintain.
