#19170 Unexpected invalidation of all paths hindering pytest runs due to excessive retries by filesystem changes Issue created by achimnol Describe the bug When I run

pants test :: -- -m 'not integration'

on a checkout of https://github.com/lablup/backend.ai on macOS, pants detects filesystem changes too frequently and restarts many pytest processes in the middle, causing resource occupation issues like overlapping of TCP port numbers calculated from execution slots, file-based locks, and etc. You could try by yourself by just cloning the repo and run the above command. No long installation is required because the test suite spawns their own database containers with fixtures locally using Docker and Docker Compose. Just ensure that

pyenv install 3.11.3 && mkdir .tmp

and have Docker Compose v2 (either Docker Desktop or OrbStack). Pants version 2.16.0rc4 (installed via scie-pants) OS It happens on macOS Ventura 13.4 only. I'm not sure about the previous macOS versions, but potentially some internal filesystem changes in recent updates like this 107550080 issue might be related somehow (this particular issue has blocked double-click opening of most Korean-named files in 13.3's Finder!). I have an Ubuntu 22.04 aarch64 VM on this Mac, but there is no symptoms like this with the same repository setup. Additional info An excerpt from `.pants.d/pants.log`:
