Slowdown in lsp-mode because the sever reports errors on TinyTex LaTeX distribution instead of only in the current project

[maikol-solis]

The whole description and logs about this issue are here (emacs-lsp/lsp-mode#4356).

The problem is that the server is sending a lot of calls for loaded packages and their TeX files, like

[Trace - 04:35:01 AM] Received notification 'textDocument/publishDiagnostics'.
Params: {
  "diagnostics": [],
  "uri": "file:///Users/maikol/Library/TinyTeX/texmf-dist/tex/latex/base/ltluatex.tex"
}

The issue was fixed by this commit (1a2ad9e), but my best guess is that this line also requires an additional filter for "tex" files.

texlab/crates/base-db/src/graph.rs

Line 80 in 1a2ad9e

let is_pkg = uri.ends_with(".sty") || uri.ends_with(".cls");

WDYT?

Best.

We cannot add this here because it would break discovering the project (e. g. \include{foo} would not find foo.tex).

I think the better solution is to never send diagnostics for files that are part of the TeX distro.

Yes, this will solve the issue completely.
