ra_lsp_server keeps hogging one core

[djc]

With f7a7092, I see one ra_lsp_server process sticking to 100% CPU while using VS Code.

[bjorn3]

Can you get a backtrace for all threads?

[djc]

How would I get it to do that?

[bjorn3]

$ gdb -p <pid of ra_lsp_server>
(gdb) thread apply all bt
(gdb) quit

Or

$ lldb -p <pid of ra_lsp_server>
(lldb) bt all
(lldb) quit

[Lapz]

I've been having the same problem as well. Heres my backtrace

[shepmaster]

Adding my backtrace to the pile. I am using lsp-mode with emacs.

% ra_lsp_server --version
rust-analyzer c6dbf40

[bkchr]

@shepmaster do you have seen similar behavior as me in #2879 ?

[shepmaster]

Yes: emacs locks up for multiple seconds and I generally need to kill the rust-analyzer process and disable lsp-mode completely.

[matklad]

This should be better in today's master, we now fuel-limit chalk.

[mnkhouri]

I'm still seeing the 100% cpu usage on master from this morning, 3bdf2e0 (backtrace)

Same issue here, on 3bdf2e0. Will update with backtrace once I have one
