IPython Console does not start if `debugpy` is not available (6.0 alpha4)

penguinpee commented 6 months ago

Description

What steps will reproduce the problem?

Start freshly installed Spyder 6 (from Fedora repo). It says connecting to kernel briefly and then displays:

[SpyderKernelApp] WARNING | debugpy_stream undefined, debugging will not be enabled

I ran Spyder 6.0.0a1 with --debug-info verbose --debug-output file, which did not actually store any debug log in spyder-debug.log. I captured the console output anyway, but didn't notice any abvious issues. The referenced debugpy_stream var appears to be from ipykernel. However the same version of ipykernel works fine with Spyder 5.

It has been reported that the same issue appears to be present in 6.0.0a4.

Hey @penguinpee, thanks for reporting. What's your debugpy version? It's not listed among your environment packages.

penguinpee commented 6 months ago

None. I don't have debugpy installed. It seems it has not yet been packaged for Fedora.

penguinpee commented 6 months ago

The displayed message is what it says on the box, a warning, due to debugpy not being installed. The reason for IPython console not starting seems unrelated to that message:

ipython_console_message

Is there a way I can easily pass parameters to the spyder_kernels.console module? E.g. adding '--debug' to the call:

Kernel command: ['/usr/bin/python3', '-Xfrozen_modules=off', '-m', spyder_kernels.console', '-f', '{connection_file}']

penguinpee commented 6 months ago

I upgraded Spyder on my test VM to version 6.0.0a4. While the issue is still there, it appears to be less severe. I found a workaround of some kind.

Start Spyder normally
Let it settle for a minute or two
Close the Ipython Console tab. That will automatically open a new tab. The initial "error" regarding debugpy_stream is gone. It now shows:

[SpyderKernelApp] WARNING | debugpy_stream undefined, debugging will not be enabled

Python 3.12.2 (main, Feb  7 2024, 00:00:00) [GCC 14.0.1 20240127 (Red Hat 14.0.1-0)]
Type "copyright", "credits" or "license" for more information.

IPython 8.21.0 -- An enhanced Interactive Python.

However, there's no prompt, no input.

Use the menu to restart the kernel. :tada:

I have a log file available. Maybe there's something in there as to why IPython Console needs some tlc.

ccordoba12 commented 6 months ago

None. I don't have debugpy installed. It seems it has not yet been packaged for Fedora.

Ok, so that's the cause of this problem (I was able to reproduce it locally). But the good news is Spyder's debugger doesn't depend on debugpy to work.

To fix this we need to skip that message as harmless, so that the console can start as expected. I'll create PR to do that for our next alpha, to be released soon.
