web2py online debugger under python3

[Clemens]

Hello everybody!

I've switched my web2py app from python2 to python3. The app itself works fine, but the web2py online debugger doesn't work anymore and is mostly freezing. Sometimes a get the following error message:

Exception timeout: timeout('timed out',)

Traceback (most recent call last): File "/usr/lib/python3.6/socket.py", line 586, in readinto return self._sock.recv_into(b) socket.timeout: timed out

My configuration is as follows:

web2py 2.19.1-stable+timestamp.2020.03.21.21.49.28 (Running on Rocket 1.2.6, Python 3.6.9), Ubuntu 18.04 LTS

What do I have to change additionally that the online debugger is working under python3?

Thanks a lot for any support!

Best regards Clemens

Hello Massimo,

I hoped the latest web2py version would fix the problem. My current configuration is now:

web2py version 2.20.4-stable+timestamp.2020.05.03.05.18.50, Running on Rocket 1.2.6, Python 3.6.9, Ubuntu 18.04., Firefox 75.0 (64-bit)

But the online debugger still doesn't work. The debugger doesn't catch the breakpoint, set in my code. Instead, after waiting a few minutes I got the following new situation:

Additional information:

Same system, running everything with python 2, the online debugger works fine (just sudo update-alternatives, thus python 2.7.17 is used):
web2py version 2.20.4-stable+timestamp.2020.05.03.05.18.50, running on Rocket 1.2.6, Python 2.7.17

Do you have any idea, how I can fix this?

Best regards

Hi Clemens

I definitely can't help you with this problem. Sorry. But I am interested in why you use the online debugger and not something else?

Thanks
Andrew

Hi Andrew,

well, I would say, it's because I ever used it and it's okay for me. But which one would you recommend? And how to connect your favorite debugger with web2py? Never used another debugger for web2py.

Regards

Clemens

Hi Clemens

I think a standalone debugger is much better. The online debugger could be great to debug applications in production  though.

Where are you doing your development? On your local machine or Python Anywhere or somewhere else?  I don't think it's possible to debug using Visual Studio Code or PyCharm if web2py is not running on your local machine. The debugger needs to connect to the python process. 

Anyhow, it's not hard to do once you know where to look. I managed to get PyCharm debugging in about 15 minutes - most of that was spent downloading the app for the first time.

Cheers

Andrew

Hi Andrew,

I've switched over to PyCharm and really like it. Thanks a lot for the push!

Best regards

Great. I have had weird problems with Visual Studio Code debugger. It seems to get confused sometimes about which line of code it is running and shows that I am executing a line different to what it is really executing. When i have that problem i switch to PyCharm and debug there. Then i head back to Visual Studio Code :)

So, what would you recommend for "remote debugging" situation?  I have web2py running on internal firewalled Windows 2016 Server and have been struggling to adopt anything for debugging purposes.

Hi Seth

I have no idea sorry. I would like to know the answer to this question though.
