No Syntax Highlighting on v2024.14.0

[axelmukwena]

Type: Bug

Behaviour

I'm running the latest Python extension v2024.14.0 which was released a few hours ago and I have lost syntax highlighting

Steps to reproduce:

1. Only have Python and Pylance (auto-installed) installed
2. Go to a file.py and hover over a Python variable and no highlighting. Imports are not highlighted, no command+click just to reference, etc

3. If you downgrade, let's say to v2024.12.3, everything will work as expected

There should be an error in the Python Language Server output that says this:

2024-09-06 09:37:45.381 [info] The language client requires VS Code version ^1.91.0 but received version 1.89.1

You would need to upgrade VS code to the latest version to use the newer Python/Pylance extension.

[rchiodo]

Internally we need to mark our engine version for both extensions to 1.91. Meaning we have a bug here in that we currently allow 1.89 for both extensions.

@IamRezaMousavi , I don't think your issue is the same. The root cause of the original issue is that Pylance requires the latest VS code now. I'm not sure what your problem is. It looks correct to me. Colorization is different for assignment vs usage.

• imported socket in line 3 and used in line 21
• assigned udp_port in line 19 and used in line 22
• assigned addr in line 28 and used in line 29
• assigned data_dict in line 34 and used in line 38
• And many other...

These items have wrong colors

[rchiodo]

I'll open a separate issue. It's still not the same as this one.

See this issue:
#6379

[StellaHuang95]

This issue has been fixed in prerelease version 2024.9.100, which we've just released. You can find the changelog here: CHANGELOG.md
