✅ Core Optimizations Implemented
1. 📊 New Database Schema: Added webdav_directories table to track
directory ETags, file counts, and metadata
2. 🔍 Smart Directory Checking: Before deep scans, check directory
ETags with lightweight Depth: 0 PROPFIND requests
3. ΓÜí Skip Unchanged Directories: If directory ETag matches, skip the
entire deep scan
4. 🗂️ N-Depth Subdirectory Tracking: Recursively track all
subdirectories found during scans
5. 🎯 Individual Subdirectory Checks: When parent unchanged, check
each known subdirectory individually
🚀 Performance Benefits
Before: Every sync = Full Depth: infinity scan of entire directory
treeAfter:
- First sync: Full scan + directory tracking setup
- Subsequent syncs: Quick ETag checks → skip unchanged directories
entirely
- Changed directories: Only scan the specific changed subdirectories
📁 How It Works
1. Initial Request: PROPFIND Depth: 0 on /Documents → get directory
ETag
2. Database Check: Compare with stored ETag for /Documents
3. If Unchanged: Check each known subdirectory (/Documents/2024,
/Documents/Archive) individually
4. If Changed: Full recursive scan + update all directory tracking
