1.1.0 appears to break ST3 compatibility

[juliangarnier]

Hi, I just posted a similar issue for the LSP-html plugin at LSP-html GitHub Issue #45, which seems to be related.

I'm using ST 3211 and it looks like LSP-css is incompatible with ST3 since 1.1.0. I installed LSP-css via package control, restarted Sublime and got this error in the console:

reloading plugin LSP-css.plugin
Traceback (most recent call last):
  File "/Applications/Sublime Text 3.app/Contents/MacOS/sublime_plugin.py", line 125, in reload_plugin
    m = importlib.import_module(modulename)
  File "./python3.3/importlib/__init__.py", line 90, in import_module
  File "<frozen importlib._bootstrap>", line 1584, in _gcd_import

ImportError: cannot import name Session
reloading plugin LSP-css.types

Manually downloading 1.0.15 to my Packages folder fixed the issue.

I know that ST3 is probably not your priority, but wanted to surface this issue just in case you didn't noticed.

Thanks.

Thanks. Fixed in 1.1.3.

[juliangarnier]

Thanks for your quick response.

Just removed 1.0.15 from the Package folder and uninstalled lsp-css and, installed 1.1.3 via the package control, restarted Sublime and got this new error:

That looks like we need to make a legacy branch for ST 3.

[juliangarnier]

Looks like 1.0.19 is working fine.

Could try whether 1.0.19 works for ST 3?

Also noticed the same type of error in lsp-json :

  File "/Applications/Sublime Text 3.app/Contents/MacOS/sublime_plugin.py", line 125, in reload_plugin

I'm afraid this error is related to a change introduced to a lot of languages...

Yeah. I think no one among LSP devs still uses ST 3.

Understandable, the only reason I'm still using ST 3 is because ST 4 has worse performances for the type of work I'm doing, at least on my current machine.

[predragnikolic]

I would suggest reporting performance issues to https://github.com/sublimehq/sublime_text

LSP functions much better with the Sublime Text 4 API. And it's the way forward.

Some LSP features don't work well or are buggy due to API limitations in ST3.

[juliangarnier]

Already reported here https://github.com/sublimehq/sublime_text/issues/6199#issuecomment-1819584932. Basically it makes working on projects using a lot of GPU ressources close to impossible with ST 4 since ST 4 also needs the GPU to render the UI. ST 3 uses the CPU for rendering, so the UI stays responsive even if my GPU is under pressure. I'm afraid I have to stick with ST3 and wait to get a more powerful GPU in order to use ST 4.

Closed since [st3-1.2.0](https://github.com/sublimelsp/LSP-css/releases/tag/st3-1.2.0) has been on Package Control.
