Application slow closing directories with .git contained #2997

Open djames-bloom opened 3 days ago

djames-bloom commented 3 days ago

Description

After upgrading to 0.10.*, closing nvim causes a long pause, up to 10 seconds.

This seems to be similar to #2438, but it is replicable with zero changes made to the cleanroom config, and is not related to node_modules or any similar large directory.

This is replicable using the absolute barebones cleanroom config without any changes made.

There appears to be no relevant info in nvim-tree.log as all logged lines occurs before the attempted close.


This behaviour has two interesting cases

  1. If any subdirectories of the open path contains a .git directory, the bug occurs, it does not only apply to the root open path
  2. The issue also persists if a .git directory simply exists without being an actual git repo

Steps to reproduce

  1. Create a new directory to test in
  2. Initialize a git repo in the directory, or create an empty .git directory within
  3. Open directory with cleanroom configuration
  4. Toggle the visibility of the tree
  5. Close the project

Expected behavior

Standard close behavior.

Actual behavior

A hang/delay of up to 10 seconds before nvim closes.

As mentioned, this issue happens when a sub-directory contains .git paths

e.g. the following structure triggers the issue

.
├── dummy.go
├── main.go
└── subdir
    └── .git

3 directories, 2 files

That +Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set). might be interesting, or may just be a difference between git implementations. Have you got anything interesting or unusual in your ~/.gitconfig?

I'd be grateful if you can perform some further tests:

Rolling back to minor versions:

cd /path/to/nvim-tree.lua
git pull
git checkout v1.7.0

When you're finished testing:

git checkout master

Hey Alex, thanks for looking into this

RE gitconfig, it doesn't look like theres anything in there that would be causing this kind of effect, but in case, you can find a copy here.

I'll update this comment once I've had a chance to run the additional tests.


Edit: testing the above results in the following, in a path in my home directory, using the cleanroom config

Disabling the above changes and testing with previous versions
