Get Web Server to run in Python 3 with GNURadio 3.8 packages

I would be interested in getting the Web Server to run in Python 3 with the GNURadio 3.8 packages. It seems like this could be accomplished independent of the demodulator conversion, by writing a Python program to simulate the serialization of the pmt key/values and pushing them over the ZMQ socket to the web server. This test program would also serve as a way to validate the functionality of the web server. Matt, what are your thoughts on this?
The webserver language (or Python version) is completely independent of the flowgraph (3.7 vs 3.8) or the webpage operation. So it can be a Python 2 or 3 Flask application or a node application. The flowgraph-to-webserver interface is ZMQ PUB/SUB and the webserver-to-webpage interface is web sockets. As long as the Python 3 conversion supports those, which it will, it will be interoperable. So there isn't a need for a PMT serializer/deserializer program.
I do agree on the utility of recording and playing back data, however. That was actually the intent of my other project gr-sqlite. If you connect a SQLite Sink to the ADS-B Decoder output that will log those packets to a database. You can create a separate flowgraph that reads back those packets (in time order) and transmits them to the webserver. That flowgraph would be a SQLite Timed Source connected to the ZMQ Pub Message Sink. I could easily create an example and add it the the examples/ directory.
If you don't mind adding an example that would be great. Sounds like gr-sqlite would be the best way to test.
Yeah, I will. It will probably be next week, though.
@potto216 this feature is now merged in. Let me know if it works for you and your thoughts.
gr-sqlite is a really cool set of components. Thanks for writing it. I was able to run the graph and it successfully transmitted locations to the webserver. The webpage was able to display the location. Now that a consistent way of generating test vectors is done should the webserver be tested with Python 3 since Python 2 support ends in December.
@potto216 sorry for not getting back sooner. Was this closed because it was no longer needed or because the webserver did work with Python 3?
Hi Matt, sorry for not documenting the reason for closing it. It was because it was no longer needed.
