Windows Performance Optimizations

Key Learnings

1. Use Docker Volumes (Not Bind Mounts)

Performance Impact: 3-5x faster installations

# ✅ FAST: Docker volumes
volumes:
    v12-data:/var/www/html/v12
    v13-data:/var/www/html/v13

# ❌ SLOW: Bind mounts
volumes:
    - type: bind
      source: ./typo3-installations/v12
      target: /var/www/html/v12

Why: Docker Desktop on Windows translates filesystem calls between Windows and Linux, making bind mounts significantly slower.

2. Fix Volume Permissions with sudo chown

# At start of install scripts
INSTALL_DIR=/var/www/html/v13
sudo rm -rf $INSTALL_DIR/*
sudo mkdir -p $INSTALL_DIR
sudo chown -R $(whoami):$(whoami) $INSTALL_DIR

This is the critical Windows fix that makes volumes work.

3. Preserve UTF-8 When Converting Line Endings

# ✅ CORRECT: Preserves emojis
$content = Get-Content $file -Raw -Encoding UTF8
$content = $content -replace "`r`n", "`n"
[System.IO.File]::WriteAllText((Resolve-Path $file).Path, $content, [System.Text.UTF8Encoding]::new($false))

# ❌ WRONG: Corrupts emojis (🚀 → ??)
(Get-Content $file -Raw) -replace "`r`n", "`n" | Set-Content -NoNewline -Encoding ASCII $file

4. Install Commands: Use Shared Base Script

DRY Principle: Don't repeat 70+ lines of installation logic

# .ddev/commands/web/install-base (80 lines, shared)
install_typo3() {
    # All common installation logic
}

# .ddev/commands/web/install-v13 (16 lines)
source /mnt/ddev_config/commands/web/install-base
SETUP_CMD="vendor/bin/typo3 setup -n ..."
install_typo3 "v13" "^13" "$SETUP_CMD"

# .ddev/commands/web/install-v12 (16 lines)  
source /mnt/ddev_config/commands/web/install-base
SETUP_CMD="vendor/bin/typo3 install:setup -n --use-existing-database ..."
install_typo3 "v12" "^12" "$SETUP_CMD"

5. TYPO3 Version Differences

Version	Setup Command	Database Creation	Extension Activation
TYPO3 13	setup	External (mysql)	extension:setup
TYPO3 12	install:setup --use-existing-database	External (mysql)	Automatic

Installation Speed Comparison

Method	v13 Install Time	Notes
Bind mounts	~10-15 min	❌ Very slow on Windows
Volumes + sudo chown	~3-5 min	✅ Fast and working
Volumes (no chown)	N/A	❌ Permission denied errors

Common Pitfalls

❌ Pitfall 1: Using Bind Mounts for Speed

# Don't do this on Windows!
volumes:
  - ./typo3-installations/v12:/var/www/html/v12

Impact: 3x slower installations

❌ Pitfall 2: Forgetting sudo chown

# This fails on Windows with volumes
echo "{}" > /var/www/html/v13/composer.json
# Permission denied!

❌ Pitfall 3: ASCII Encoding Corrupts Emojis

# This breaks emojis in bash scripts
Set-Content -Encoding ASCII $file

❌ Pitfall 4: TYPO3 12 Database Creation

# This hangs/fails
vendor/bin/typo3 install:setup -n --database-name v12
# Missing: --use-existing-database

Recommended Workflow

1. Use skill templates - They have the correct volume setup
2. Add sudo chown - Fix volume permissions (Windows-specific)
3. Use UTF-8 encoding - Preserve emojis when converting line endings
4. Share install logic - Use install-base for DRY principle
5. Test both versions - TYPO3 12 and 13 have different setup commands

Windows-Specific .gitignore

# Don't commit these (Windows creates them)
.ddev/typo3-installations/
Thumbs.db
desktop.ini

Quick Reference Commands

# Convert to LF with UTF-8 (correct)
$file = '.ddev/commands/web/install-v13'
$content = Get-Content $file -Raw -Encoding UTF8
$content = $content -replace "`r`n", "`n"
[System.IO.File]::WriteAllText((Resolve-Path $file).Path, $content, [System.Text.UTF8Encoding]::new($false))

# Restart DDEV after config changes
ddev restart

# Check volume ownership
ddev exec ls -la /var/www/html/v13

# Fix permissions manually if needed
ddev exec sudo chown -R $(whoami):$(whoami) /var/www/html/v13
