How does the FSMonitor hook eliminate working directory scan delays on macOS and Windows?
❓ Interview Prompt: Explain FSMonitor (File System Monitor), OS native file watching APIs (FSEvents, ReadDirectoryChangesW), and bypassing full directory stat calls.
FSMonitor integrates Git with OS native file watching daemons (macOS FSEvents / Windows ReadDirectoryChangesW), informing Git of modified files instantly and bypassing full directory stat scans.
Code Implementation Example
bash
git config --global core.fsmonitor true
git config --global core.untrackedcache true💡Enabling native FSMonitor background daemon for instant git status responses.
🎯 Interview Key Takeaway
Enable core.fsmonitor to leverage OS file watching daemons, bypassing full filesystem directory scans for instant git status.
