In emacs-lsp, super slow f-string completion with open parenthesis #378

Hello,

I think I have a bug but I'm not sure it if is pyslp or emacs-lsp-mode that is the culprit.

It's 100% reproducible. Scenario is:

start an f-string like print(f"hello")
insert an open parenthesis/accolade/bracket
wait 10 seconds for emacs to respond again. Yes it's that long...

I can provide debug information if someone tells me how to get them.

Cheers, and thanks for providing us with a non-msft tool !

After some tests, it appears the issue depends on the size of the file and the power of the computer I'm using. So maybe it's not a bug, it's "just" a performance issue...

i've run into a similar issue without lsp, only default python mode. until { is closed, typing is extremely slow (1-2s per character). and yeah, can also confirm it depends on file size
