OP25 Docker Image Created / Looking for Testing

It was the home stretch and as soon as I saw it I knew that one would be easy to fix.

The buffered stderr had me scratching my head for quite a while. What a crazy decision on the part of the python developers!!

The buffered stderr had me scratching my head for quite a while. What a crazy decision on the part of the python developers!!

I didn't even know about the buffer since I hadn't had a chance to use stderr (was mostly doing django). I did some research and I can see how that is a problem in OP25 haha.

Looks like there might be another error with the HTTP interface.

The first error is osmosdr source_c creation failure with the full error being:

gr-osmosdr 0.2.0.0 (0.2.0) gnuradio 3.8.1.0

That error normally happens when gr-osmosdr cannot find the sdr hardware. Does the rtl device show up when you run "lsusb" command?

Woops, you're right. I forgot to attach it to my VM. All good now!

Actually, I'm getting this error now:

Looking at it now

Please pull the update and try it again.

Please pull the update and try it again.

I'll be home in about an hour and a half. I'll pull then!

 

[NebraskaCoder]

Looks good! Thank you!

Opened a new issue on GitHub at DEV HTTP Interface Errors · Issue #87 · boatbod/op25

Fixes posted and available in origin/master (as well as origin/dev). I've tested the gui commands and fixed a couple non-python3 bugs I ran across along the way.

If anyone has a suitable testing environment with the ability to make an apples-apples comparison, I would be curious to compare CPU utilization of op25 under gr3.8/py3 versus the same hardware & configuration running on gr3.7/py2.

As an aside, my test environment is happily running an Airspy @ 3.0Mhz with glitch-free audio via the much-maligned 'pulse' subsystem on Ubuntu 20.04 in a virtual environment using Virtualbox on host Mint 18.3 (Ubuntu 16.04).

I have VMWare workstation, so I can create two VMs to do testing on the same CPU(s). I'll do Ubuntu 18.04 and Ubuntu 20.04 for testing.
