Call Hierarchy result is incomplete when clangd run with remote index environment

[simon8233]

Hi everyone,

I not sure it's misconfiguration or bugs.

I used clangd-indexer to generate index file and deploy clangd remote index server in internal
environments

Everything is work until I use "Show Call Hierarchy" feature in VS Code.
(Find All References with remote index is work and very fast , remote index is powerful and smoothly )

I use Show Call Hierarchy button on VScode with Remote Index .

It seem clangd only refers opened file and show corresponding info.
(It means overall Call Hierarchy is incomplete in whole codebase)

but, when I build up background index is workable and can provide correct and all "Call Hierarchy" information.

I try to enable --log=verbose in remote index server and clangd process

request v1/Refs => OK: 48 result in 2ms
request v1/Lookup => OK 1 result in 0ms

It seems first request found correct references count
but, Lookup is incorrect result.. I not sure why clangd filter out references result

Very thanks for your reading.
anyone can help give some suggestion. I very appreciate it

It's sys information
Clangd / Clangd Remote index version : 14
Editor/LSP plugin: VScode + Clangd
Operating system: Linux u1804

Folks following this thread: if you're able to try the patch at llvm/llvm-project#71605 and see whether it fixes the problem, that would be helpful info
