ccls hangs when there are too many files to watch #59

Closed ztlevi closed 5 years ago

ztlevi commented 5 years ago

My project is based on bazel. Once I generated proper compile_commands.json. It works fine but it will hang emacs when bootstrapping emacs and open a cc file. I need to press C-g couple times to stop it.

I tried to set lsp-file-watch-threshold to nil but no luck get it working.

I'm closing this because I found I need to have proper regex to exclude symlinked folders, e.g. bazel-code.

  (dolist (dir '("[/\\\\]\\.ccls-cache$"
                 "[/\\\\]\\.mypy-cache$"
                 "[/\\\\]\\.pytest-cache$"
                 "bazel-bin$"
                 "bazel-code$"
                 "bazel-genfiles$"
                 "bazel-out$"
                 "bazel-testlogs$"
                 "[/\\\\]\\.clwb$"
                 ))
    (push dir lsp-file-watch-ignored))
