Anaconda server crash due to Jedi version

[RaytingSec]

Expected Behaviour

Open a python file with ST, Anaconda provides it's features such as docs, autocomplete, and linting

Actual Behaviour

ConnectionRefusedError is thrown

Steps to Reproduce

• Fresh install of Fedora 40, install sublime-text

• Set syntax to Python

• Write a python script that makes use of other libraries such as:

  import datetime
  
  dt = datetime.now()

• While writing the last line, the autocomplete should throw an error

ST3, Anaconda and OS versions

• Sublime Text 4180
• Anaconda 2.3.0
• Fedora 40
• Python 3.12.6 (system version)

ST3 Console Logs

Anaconda's JsonServer Logs

Note: Anaconda's JsonServer logs can be found in:

• Linux: ~/.local/share/anaconda/logs
• OS X: ~/Library/Logs/anaconda
• Windows: %APPDATA\Anaconda\Logs

See Troubleshooting section

Troubleshooting

TLDR, it seems the Jedi version need to be bumped.

For a while now, Anaconda's server is unable to start up and I get this as part of the error in ST console:

ConnectionRefusedError: [Errno 111] Connection refused

I'm unable to find a detailed message unless I run jsonserver.py myself, then I can see more detailed message like stacktrace:

    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: too many values to unpack (expected 2)

After much digging and troubleshooting, I found when I install Jedi via pip, it's the latest version jedi-0.19.1 and some of the code such as allowed_getattr_callback() involved in the too many values to unpack has changed. It returns three instead of two.

I attempted a crude patch by rsync from .venv/lib/python3.12/site-packages/jedi/ to ~/.config/sublime-text/Packages/Anaconda/anaconda_lib/jedi/, and Anaconda appears to be working fine now. I have linting and autocomplete again, and I no longer see errors in my ~/.local/share/anaconda/ logs.

Edit: I can open a PR, or try checking for other library updates. But how can I test the changes, or who is able to test it? Long time user and happy to contribute a bit to a tool I love.

There's a second problem involving virtual environments, where the JSON server doesn't start and results in the connection refused error:

anacondaST3: ERROR - Anaconda worker could not start because:

can not connect to /home/rayting/.local/share/anaconda/run/anacondatest/anaconda.sock. tried to connect 21 times during 2.0 seconds

check that there is Python process executing the anaconda jsonserver.py script running in your system. If there is, check that the Unix Domain Socket file /home/rayting/.local/share/anaconda/run/anacondatest/anaconda.sock exists and that you can connect to it writing the following script in your Sublime Text 3 console:

import socket; socket.socket(socket.AF_UNIX, socket.SOCK_STREAM).connect(/home/rayting/.local/share/anaconda/run/anacondatest/anaconda.sock)

If anaconda works just fine after you received this error and the command above worked you can make anaconda to do not show you this error anymore setting the 'swallow_startup_errors' to 'true' in your configuration file.

Steps to reproduce

• Create a new folder and virtualenv, such as:

  mkdir anacondatest && cd anacondatest
  virtualenv .venv && source .venv/bin/activate
  subl -n ./

• Save it as a new project in ST

• Edit the project to use the virtualenv python, for example, this is what I have:

  {
      "folders":
      [
          {
              "follow_symlinks": true,
              "path": "/home/rayting/code/anacondatest",
          }
      ],
      "build_systems":
      [
          {
              "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
              "name": "Anaconda Python Builder",
              "selector": "source.python",
              "shell_cmd": "\"/home/rayting/code/anacondatest/.venv/bin/python\" -u \"$file\"",
          }
      ],
      "settings":
      {
          "python_interpreter": "/home/rayting/code/anacondatest/.venv/bin/python"
      }
  }

• Create a python file and follow the original reproduction steps with import datetime and such

• A new python process running jsonserver.py will not spawn, for example this is my ps aux | grep [s]ubl output:

• I found it's because pyasynchat needs to be installed manually in the virtualenv, then the relevant processes will start:
