Bug ID: 450190
Summary: The LSP server is started once per window
Product: kate
Version: 21.12.2
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: m_loui...@yahoo.com
Target Milestone: ---
SUMMARY
When two windows are open, each starts its own LSP server. This results in a
waste of resources and duplicated work. RAM usage is especially bad since for
large code bases, clang-format easily reaches 1GB per instance.
STEPS TO REPRODUCE
1. Open a file type with LSP support (and, obviously, the LSP plugin enabled).
I use clang-format with C++.
2. Open a new window (View > New window)
3. Open your task manager and count the number of LSP server instances
OBSERVED RESULT
There are as many LSP servers as there are windows open.
EXPECTED RESULT
A single LSP server is spawned.
