This patch adds the ability for plugins to send multiple messages
back in response to a command/message. The plugin simple needs
to return a list of messages (Strings). Each string in that list
will result in a separate message being sent back to the originator
of the message.
This patch updates the notification thread to send all packets
through the notification plugins. The plugins themselves need to
do smart filter to not reply to every packet. This allows for
more interesting plugins.
Also fixed an issue with the messages tab in the admin ui, not
showing all of the recieved packets. The messages tab now also
sees all the packets that aprsd recieves.
This patch adds a new optional feature called Watch list.
Aprsd will filter IN all aprs packets from a list of callsigns.
APRSD will keep track of the last time a callsign has been seen.
When the configured timeout value has been reached, the next time
a callsign is seen, APRSD will send the next packet from that callsign
through the new notification plugins list.
The new BaseNotifyPlugin is the default core APRSD notify based plugin.
When it gets a packet it will construct a reply message to be sent
to the configured alert callsign to alert them that the seen callsign
is now on the APRS network.
This basically acts as a notification that your watched callsign list is
available on APRS.
The new configuration options:
aprsd:
watch_list:
# The callsign to send a message to once a watch list callsign
# is now seen on APRS-IS
alert_callsign: NOCALL
# The time in seconds to wait for notification.
# The default is 12 hours.
alert_time_seconds: 43200
# The list of callsigns to watch for
callsigns:
- WB4BOR
- KFART
# Enable/disable this feature
enabled: false
# The list of notify based plugins to load for
# processing a new seen packet from a callsign.
enabled_plugins:
- aprsd.plugins.notify.BaseNotifyPlugin
This patch also adds a new section in the Admin UI for showing the
watch list and the age of the last seen packet for each callsing since
APRSD startup.
This patch updates the admin UI to include 3 tabs
of content.
Charts
messages
config
The charts tab is the existing line charts.
The messages tab shows a list of RX (green) and TX (red) messages
from/to aprsd.
The config tab shows the config loaded at startup time.
This patch adds usage of update_checker to check to make sure the
version of APRSD being launched is the latest version. Also added a
call to upate_checker as part of the KeepAlive thread. It will
call update_check every hour. If there is no aprsd connectivitity,
the update check will silently fail.
This patch reworks the stats object dict and includes more data.
Also includes aprsis last update timestamp (from last recieved message).
This is used to help determine if the aprsis server connection is still
alive and well.
This patch adds the stats object to collect statistics of
the running server. This also optionally adds the ability
to run a flask web service on a port to use as a keepalive
healthcheck.
This patch adds the new MsgTrack object replacing the
global ack_dict. the ack_dict was not thread safe.
the new MsgTrack is a singleton object that keeps track of
all outbound TextMessage objects. When a TextMessage.send() is called
it is added to the MsgTrack object, and when an ack is received for that
message, the message is removed from the MsgTrack object.
TODO: Add an automatic mechanism for saving the messages in MsgTrack
so that when CTRL-C is called to exit aprsd server, then the MsgTrack
state is saved to storage. When aprsd server is started up again, add
the option to try and reload state of MsgTrack.
This patch also reworked the email thread into an APRSDThread object
that can exit gracefully with CTRL-C.
NOTE: Don't call sleep() with a long time (greater than 5 seconds), as
it causes a delay in exiting aprsd until the last sleep() finishes.
Since aprsd has so many threads now for processing incoming messages and
outgoing messages, we need to coordinate all thread operations so that
they don't block the exiting of the app.
This patch reworks the threading code for processing
messages. This patch also extends the aprslib IS class
to allow us to stop processing the consumer packets when
someone hits CTRL-C correctly. Alloing the app to exit.
