WEBUI don´t work with Python 3 #79

Closed fernando-inf closed 3 years ago

fernando-inf commented 3 years ago

It should be added in the README of guitarix/trunk/webui/that WEBUI does not work with python 3, python 2.7-minimal must be installed and thus start the server with python2.7 inside the websockify folder: python2.7 websocketproxy.py --web = .. / '*': 8000 127.0.0.1:7000

Yes, that is true. It may require some work to make the included websockety app compatible with python3.

I hacked an Ansible playbook together to run guitarix on an RPi, and I have a quick-and-dirty patch inline there which has got me unblocked: https://gist.github.com/OddBloke/bc0c13f7b65095ae52ed23d94e659fbf

Hi, thanks a lot @OddBloke . Still here on debian/sid it requires some more fixes, but your patch get me going.

Hi, I have compiled Guitarix today and notice that WEBUI already works with python 3, so this problem is fixed.

However I see that the selection of Banks is not available, I attach a video: https://youtu.be/QXt0s6PrVjo

Strange. Here it works as expected with both (python2 and python3) From what I could see you running the debug version of the webui, please build the deploy version of the webui and try again. The connection of the deployed version is much faster because we could cache the UI stuff in the browser. If it still don't work with the deployed version, please start the server in verbose mode to get some info what goes wrong (just add -v at the end of the command (after :7000))

Hi Brummer, thanks for the help, now it works fine. Although I do not know what the problem was. At first I thought it was because I had many banks. Likewise Run bash deploy.sh, then reboot the machine and it works fine.

On the other hand, I notice in the task manager that python runs doubly, taking up twice the RAM, but only one process uses the CPU, usually at 1%. guitarix-webui

Two processes been to be expected, as it use multiprocessing for the worker thread. However, you've to take the memory usage shown in the process table with a grain of salt, as the memory (for the static data) is mostly shared between both processes, so the real memory usage of both processes is lower then shown by the process table.
