+# Configuration System Overhaul - Summary
+
+## Problem Identified
+
+The application was **not bundling the `.env` configuration file** into built executables. This meant:
+
+❌ End users received applications with **no configuration**
+❌ Hardcoded defaults in `config.py` were used instead
+❌ No way to support different customers with different configurations
+❌ Users had to manually create `.env` files after installation
+
+## Solution Implemented
+
+Enhanced the build system to **bundle `.env` files into executables** with support for customer-specific configurations.
+
+### Key Changes
+
+#### 1. **Windows Build Script** (`build/scripts/build_windows.py`)
+- Added `--env-file` command-line parameter
+- Validates `.env` file exists before building
+- Passes `.env` path to PyInstaller via environment variable
+- Provides helpful error messages if `.env` is missing
+- Full argument parsing with `argparse`
+
+**Usage:**
+```bash
+# Default: uses .env from project root
+python build_windows.py --msi
+
+# Custom config for a customer
+python build_windows.py --msi --env-file customer_configs/acme.env
+```
+
+#### 2. **macOS Build Script** (`build/scripts/build_macos.sh`)
+- Added `--env-file` parameter (shell-based)
+- Validates `.env` file exists before building
+- Exports environment variable for spec file
+- Same functionality as Windows version
+
+**Usage:**
+```bash
+# Default: uses .env from project root
+bash build_macos.sh
+
+# Custom config
+bash build_macos.sh --env-file customer_configs/acme.env
+```
+
+#### 3. **PyInstaller Spec File** (`build/webdrop_bridge.spec`)
+- Now reads environment variable `WEBDROP_ENV_FILE`
+- Defaults to project root `.env` if not specified
+- **Validates .env exists** before bundling
+- Includes `.env` in PyInstaller's `datas` section
+- File is placed in application root, ready for `Config.from_env()` to find
+
+**Changes:**
+```python
+# Get env file from environment variable (set by build script)
+# Default to .env in project root if not specified
+env_file = os.getenv("WEBDROP_ENV_FILE", os.path.join(project_root, ".env"))
+
+# Verify env file exists
+if not os.path.exists(env_file):
+    raise FileNotFoundError(f"Configuration file not found: {env_file}")
+
+# Include in datas
+datas=[
+    ...
+    (env_file, "."),  # Include .env file in the root of bundled app
+]
+```
+
+#### 4. **Documentation** (`docs/CONFIGURATION_BUILD.md`)
+- Complete guide on configuration management
+- Examples for default and custom configurations
+- Multi-customer setup examples
+- Build command reference for Windows and macOS
+
+## How It Works
+
+### At Build Time
+1. User specifies `.env` file (or uses default from project root)
+2. Build script validates the file exists
+3. PyInstaller bundles the `.env` into the application
+4. Users receive a pre-configured executable
+
+### At Runtime
+1. Application starts and calls `Config.from_env()`
+2. Looks for `.env` in the current working directory
+3. Finds the bundled `.env` file
+4. Loads all configuration (URLs, paths, logging, etc.)
+5. Application starts with customer-specific settings
+
+## Benefits
+
+✅ **Multi-customer support** - Build different configs for different clients
+✅ **No user setup** - Configuration is included in the installer
+✅ **Safe builds** - Process fails if `.env` doesn't exist
+✅ **Override capability** - Users can edit `.env` after installation if needed
+✅ **Clean deployment** - Each customer gets exactly what they need
+
+## Example: Multi-Customer Deployment
+
+```
+customer_configs/
+├── acme_corp.env
+│   WEBAPP_URL=https://acme.example.com
+│   ALLOWED_ROOTS=Z:/acme_files/
+├── globex.env
+│   WEBAPP_URL=https://globex.example.com
+│   ALLOWED_ROOTS=C:/globex_data/
+└── initech.env
+    WEBAPP_URL=https://initech.example.com
+    ALLOWED_ROOTS=D:/initech/
+```
+
+Build for each:
+```bash
+python build_windows.py --msi --env-file customer_configs/acme_corp.env
+python build_windows.py --msi --env-file customer_configs/globex.env
+python build_windows.py --msi --env-file customer_configs/initech.env
+```
+
+Each MSI includes the customer's specific configuration.
+
+## Files Modified
+
+1. ✅ `build/scripts/build_windows.py` - Enhanced with `.env` support
+2. ✅ `build/scripts/build_macos.sh` - Enhanced with `.env` support
+3. ✅ `build/webdrop_bridge.spec` - Now includes `.env` in bundle
+4. ✅ `docs/CONFIGURATION_BUILD.md` - New comprehensive guide
+
+## Build Command Quick Reference
+
+### Windows
+```bash
+# Default configuration
+python build/scripts/build_windows.py --msi
+
+# Custom configuration
+python build/scripts/build_windows.py --msi --env-file path/to/config.env
+
+# Without MSI (just EXE)
+python build/scripts/build_windows.py
+
+# With code signing
+python build/scripts/build_windows.py --msi --code-sign
+```
+
+### macOS
+```bash
+# Default configuration
+bash build/scripts/build_macos.sh
+
+# Custom configuration
+bash build/scripts/build_macos.sh --env-file path/to/config.env
+
+# With signing
+bash build/scripts/build_macos.sh --sign
+
+# With notarization
+bash build/scripts/build_macos.sh --notarize
+```
+
+## Testing
+
+To test the new functionality:
+
+```bash
+# 1. Verify default build (uses project .env)
+python build/scripts/build_windows.py --help
+
+# 2. Create a test .env with custom values
+# (or use existing .env)
+
+# 3. Try building (will include .env)
+# python build/scripts/build_windows.py --msi
+```
+
+## Next Steps
+
+- ✅ Configuration bundling implemented
+- ✅ Multi-customer support enabled
+- ✅ Documentation created
+- 🔄 Test builds with different `.env` files (optional)
+- 🔄 Document in DEVELOPMENT_PLAN.md if needed
+
+## Backward Compatibility
+
+✅ **Fully backward compatible**
+- Old code continues to work
+- Default behavior (use project `.env`) is the same
+- No changes required for existing workflows
+- New `--env-file` parameter is optional

-# WebDrop Bridge Configuration Guide
-
-## Configuration File Location
-
-WebDrop Bridge supports two configuration methods:
-
-1. **JSON Configuration File** (Recommended for Azure URL mapping)
-   - Windows: `%APPDATA%\webdrop_bridge\config.json`
-   - macOS/Linux: `~/.config/webdrop_bridge/config.json`
-
-2. **Environment Variables** (`.env` file in project root)
-   - Used as fallback if JSON config doesn't exist
-
-## JSON Configuration Format
-
-Create a `config.json` file with the following structure:
-
-```json
-{
-  "app_name": "WebDrop Bridge",
-  "webapp_url": "https://wps.agravity.io/",
-  "url_mappings": [
-    {
-      "url_prefix": "https://wpsagravitystg.file.core.windows.net/wpsagravitysync/",
-      "local_path": "Z:"
-    }
-  ],
-  "allowed_roots": [
-    "Z:\\"
-  ],
-  "allowed_urls": [],
-  "check_file_exists": true,
-  "auto_check_updates": true,
-  "update_check_interval_hours": 24,
-  "log_level": "INFO",
-  "log_file": "logs/webdrop_bridge.log",
-  "window_width": 1024,
-  "window_height": 768,
-  "enable_logging": true
-}
-```
-
-## Configuration Options
-
-### Core Settings
-
-- **`webapp_url`** (string): URL of the web application to load
-  - Example: `"https://wps.agravity.io/"`
-  - Supports `http://`, `https://`, or `file:///` URLs
-
-- **`url_mappings`** (array): Azure Blob Storage URL to local path mappings
-  - Each mapping has:
-    - `url_prefix`: Azure URL prefix (must end with `/`)
-    - `local_path`: Local drive letter or path
-  - Example:
-    ```json
-    {
-      "url_prefix": "https://wpsagravitystg.file.core.windows.net/wpsagravitysync/",
-      "local_path": "Z:"
-    }
-    ```
-
-- **`allowed_roots`** (array): Whitelisted root directories for file access
-  - Security feature: Only files within these directories can be dragged
-  - Example: `["Z:\\", "C:\\Users\\Public"]`
-
-### Azure URL Mapping Example
-
-When the web application provides a drag URL like:
-```
-https://wpsagravitystg.file.core.windows.net/wpsagravitysync/aN5PysnXIuRECzcRbvHkjL7g0/Hintergrund_Agravity.png
-```
-
-It will be converted to:
-```
-Z:\aN5PysnXIuRECzcRbvHkjL7g0\Hintergrund_Agravity.png
-```
-
-### Security Settings
-
-- **`check_file_exists`** (boolean): Validate files exist before allowing drag
-  - Default: `true`
-  - Set to `false` only for testing
-
-- **`allowed_urls`** (array): Allowed URL patterns for web content
-  - Empty array = no restriction
-  - Example: `["wps.agravity.io", "*.example.com"]`
-
-### Update Settings
-
-- **`auto_check_updates`** (boolean): Automatically check for updates on startup
-  - Default: `true`
-
-- **`update_check_interval_hours`** (number): Hours between update checks
-  - Default: `24`
-
-### UI Settings
-
-- **`window_width`**, **`window_height`** (number): Initial window size in pixels
-  - Default: `1024` x `768`
-
-- **`log_level`** (string): Logging verbosity
-  - Options: `"DEBUG"`, `"INFO"`, `"WARNING"`, `"ERROR"`, `"CRITICAL"`
-  - Default: `"INFO"`
-
-- **`enable_logging`** (boolean): Whether to write logs to file
-  - Default: `true`
-
-## Quick Start
-
-1. Copy `config.example.json` to your config directory:
-   ```powershell
-   # Windows
-   mkdir "$env:APPDATA\webdrop_bridge"
-   copy config.example.json "$env:APPDATA\webdrop_bridge\config.json"
-   ```
-
-2. Edit the configuration file with your Azure URL mappings and local paths
-
-3. Restart WebDrop Bridge
-
-## Multiple URL Mappings
-
-You can configure multiple Azure storage accounts:
-
-```json
-{
-  "url_mappings": [
-    {
-      "url_prefix": "https://storage1.file.core.windows.net/container1/",
-      "local_path": "Z:"
-    },
-    {
-      "url_prefix": "https://storage2.file.core.windows.net/container2/",
-      "local_path": "Y:"
-    }
-  ],
-  "allowed_roots": [
-    "Z:\\",
-    "Y:\\"
-  ]
-}
-```
-
-## Environment Variable Fallback
-
-If no JSON config exists, WebDrop Bridge will load from `.env`:
-
-```env
-APP_NAME=WebDrop Bridge
-WEBAPP_URL=https://wps.agravity.io/
-ALLOWED_ROOTS=Z:/
-LOG_LEVEL=INFO
-WINDOW_WIDTH=1024
-WINDOW_HEIGHT=768
-```
-
-**Note:** Environment variables don't support `url_mappings`. Use JSON config for Azure URL mapping.
-
-## Troubleshooting
-
-### "No mapping found for URL"
-- Check that `url_prefix` matches the Azure URL exactly (including trailing `/`)
-- Verify `url_mappings` is configured in your JSON config file
-- Check logs in `logs/webdrop_bridge.log`
-
-### "Path is not within allowed roots"
-- Ensure the mapped local path (e.g., `Z:`) is listed in `allowed_roots`
-- Make sure the drive is mounted and accessible
-
-### "File does not exist"
-- Verify the Azure sync is working and files are available locally
-- Set `check_file_exists: false` temporarily for testing
-- Check that the path mapping is correct
-
-## Example Configurations
-
-### Production (Agravity WPS)
-
-```json
-{
-  "webapp_url": "https://wps.agravity.io/",
-  "url_mappings": [
-    {
-      "url_prefix": "https://wpsagravitystg.file.core.windows.net/wpsagravitysync/",
-      "local_path": "Z:"
-    }
-  ],
-  "allowed_roots": ["Z:\\"],
-  "log_level": "INFO"
-}
-```
-
-### Development (Local Testing)
-
-```json
-{
-  "webapp_url": "file:///./webapp/index.html",
-  "url_mappings": [
-    {
-      "url_prefix": "https://test.blob.core.windows.net/test/",
-      "local_path": "C:\\temp\\test"
-    }
-  ],
-  "allowed_roots": ["C:\\temp\\test"],
-  "check_file_exists": false,
-  "log_level": "DEBUG"
-}

+# Forgejo Releases Distribution Guide
+
+This guide explains how to distribute WebDrop Bridge builds using **Forgejo Releases** with binary assets.
+
+## Overview
+
+**Forgejo Releases** is the standard way to distribute binaries. Attach exe/dmg and checksum files to releases.
+
+```
+1. Build locally (Windows & macOS)
+2. Create Release (v1.0.0)
+3. Upload exe + dmg as release assets
+4. UpdateManager downloads from release
+5. Users verify with SHA256 checksums
+```
+
+## Setup Requirements
+
+### 1. Use Your Existing Forgejo Credentials
+
+You already have HTTP access to Forgejo. Just use the same username and password you use to log in.
+
+Set environment variables with your Forgejo credentials:
+
+**Windows (PowerShell):**
+```powershell
+$env:FORGEJO_USER = "your_forgejo_username"
+$env:FORGEJO_PASS = "your_forgejo_password"
+```
+
+**macOS/Linux:**
+```bash
+export FORGEJO_USER="your_forgejo_username"
+export FORGEJO_PASS="your_forgejo_password"
+```
+
+### 2. Build Scripts
+
+Upload scripts are already created:
+- Windows: `build/scripts/upload_to_packages.ps1`
+- macOS: `build/scripts/upload_to_packages.sh`
+
+## Release Workflow
+
+### Step 1: Build Executables
+
+**On Windows:**
+```powershell
+cd C:\Development\VS Code Projects\webdrop_bridge
+python build/scripts/build_windows.py
+# Output: build/dist/windows/WebDropBridge.exe
+#         build/dist/windows/WebDropBridge.exe.sha256
+```
+
+**On macOS:**
+```bash
+cd ~/webdrop_bridge
+bash build/scripts/build_macos.sh
+# Output: build/dist/macos/WebDropBridge.dmg
+#         build/dist/macos/WebDropBridge.dmg.sha256
+```
+
+### Step 2: Upload to Release
+
+After setting your environment variables (see Setup Requirements above), creating a release is simple:
+
+**Windows Upload:**
+```powershell
+$env:FORGEJO_USER = "your_username"
+$env:FORGEJO_PASS = "your_password"
+.\build\scripts\create_release.ps1 -Version 1.0.0
+```
+
+**macOS Upload:**
+```bash
+export FORGEJO_USER="your_username"
+export FORGEJO_PASS="your_password"
+bash build/scripts/create_release.sh -v 1.0.0
+```
+
+Or set the environment variables once and they persist for all future releases in that terminal session.
+
+The script will:
+1. Create a release with tag `v1.0.0`
+2. Upload the executable as an asset
+3. Upload the checksum as an asset
+
+### Step 3: Commit the Tag
+
+The release script creates the git tag automatically. Push it:
+
+```bash
+git push upstream v1.0.0
+```
+
+## Forgejo Releases API
+
+### Get Latest Release
+
+```bash
+curl https://git.him-tools.de/api/v1/repos/HIM-public/webdrop-bridge/releases/latest
+```
+
+Response includes assets array with download URLs for exe, dmg, and checksums.
+
+### Download URLs
+
+After creating a release, assets are available at:
+```
+https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v1.0.0/WebDropBridge.exe
+https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v1.0.0/WebDropBridge.exe.sha256
+```
+
+### Direct Release Page
+
+```
+https://git.him-tools.de/HIM-public/webdrop-bridge/releases
+```
+
+## UpdateManager Integration (Phase 4.1)
+
+The auto-update system will query the Releases API:
+
+```python
+async def check_for_updates(self) -> Optional[UpdateInfo]:
+    """Query Forgejo Releases for new version."""
+    url = "https://git.him-tools.de/api/v1/repos/HIM-public/webdrop-bridge/releases/latest"
+    response = await session.get(url)
+    release = response.json()
+    
+    # Get version from tag
+    tag_version = release['tag_name'].lstrip('v')
+    
+    # Compare versions
+    if parse_version(tag_version) > parse_version(self.current_version):
+        # Find exe and checksum assets
+        assets = release.get('assets', [])
+        exe_asset = next((a for a in assets if a['name'].endswith('.exe')), None)
+        checksum_asset = next((a for a in assets if a['name'].endswith('.sha256')), None)
+        
+        if exe_asset and checksum_asset:
+            return UpdateInfo(
+                version=tag_version,
+                download_url=exe_asset['browser_download_url'],
+                checksum_url=checksum_asset['browser_download_url']
+            )
+    
+    return None
+```
+
+## Troubleshooting
+
+### Release creation fails with "409 Conflict"
+
+- Tag already exists
+- Use a different version number
+
+### Release creation fails with "401 Unauthorized"
+
+- Verify credentials are correct
+- Check you have write access to repo
+
+### Asset upload fails
+
+- Check file exists and is readable
+- Verify file isn't too large (Forgejo may have limits)
+- Try again, transient network issues can occur
+
+### Where are my releases?
+
+View all releases at:
+```
+https://git.him-tools.de/HIM-public/webdrop-bridge/releases
+```
+
+Each release shows:
+- Version/tag name
+- Release date
+- Release notes
+- Attached assets with download links
+
+## Manual Download
+
+Users can download directly from releases:
+```
+https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v1.0.0/WebDropBridge.exe
+https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v1.0.0/WebDropBridge.dmg
+```
+
+Or via Releases page UI:
+```

+
+
+## Release Script Details
+
+### Windows Script (`create_release.ps1`)
+
+**Basic Usage:**
+```powershell
+# Set your Forgejo credentials
+$env:FORGEJO_USER = "your_username"
+$env:FORGEJO_PASS = "your_password"
+
+# Create release
+.\build\scripts\create_release.ps1 -Version 1.0.0
+```
+
+**Parameters:**
+- `-Version` - Version number (required, e.g., "1.0.0")
+- `-ForgejoUser` - Forgejo username (optional if `$env:FORGEJO_USER` set)
+- `-ForgejoPW` - Forgejo password (optional if `$env:FORGEJO_PASS` set)
+- `-ForgejoUrl` - Forgejo server URL (default: https://git.him-tools.de)
+- `-Repo` - Repository (default: HIM-public/webdrop-bridge)
+- `-ExePath` - Path to exe file (default: build\dist\windows\WebDropBridge.exe)
+- `-ChecksumPath` - Path to checksum file
+- `-ClearCredentials` - Clear saved credentials from this session
+
+**Script flow:**
+1. Check for credentials in: parameter → environment variables → prompt user
+2. Save credentials to environment for future use
+3. Create release with tag `v{Version}`
+4. Upload exe as asset
+5. Upload checksum as asset
+6. Show success message with release URL
+
+### macOS Script (`create_release.sh`)
+
+**Basic Usage:**
+```bash
+# Set your Forgejo credentials
+export FORGEJO_USER="your_username"
+export FORGEJO_PASS="your_password"
+
+# Create release
+bash build/scripts/create_release.sh -v 1.0.0
+```
+
+**Options:**
+- `-v, --version` - Version number (required, e.g., "1.0.0")
+- `-u, --url` - Forgejo server URL (default: https://git.him-tools.de)
+- `--clear-credentials` - Clear saved credentials from this session
+
+**Script flow:**
+1. Check for credentials in: environment variables → prompt user
+2. Export credentials for future use
+3. Create release with tag `v{Version}`
+4. Upload dmg as asset
+5. Upload checksum as asset
+6. Show success message with release URL
+
+### Credential Resolution
+
+Both scripts use HTTP Basic Authentication with your Forgejo username/password:
+- Same credentials you use to log into Forgejo
+- Same credentials git uses when cloning over HTTPS
+- No special token creation needed
+- First run prompts for credentials, saves to session
+

+4. Release visible on Forgejo within seconds
+
+---
+
+## Next Steps
+
+### Immediate (Phase 3 Completion)
+
+1. ✅ **Windows Release Workflow** - COMPLETE
+   - Build executable with checksum
+   - Create release on Forgejo
+   - Upload assets (exe + checksum)
+   - Tested with v0.0.2 release
+
+2. ⏳ **macOS Release Workflow** - Script ready, untested
+   - Requires macOS machine to test
+   - Script `create_release.sh` ready to use
+   - Same workflow as Windows version
+
+3. ⏳ **Push Release Tags** (Optional but recommended)
+   ```bash
+   git tag -a v0.0.2 -m "Release 0.0.2"
+   git push upstream v0.0.2
+   ```
+
+### Phase 4.1: Auto-Update System (Next Phase)
+
+The release infrastructure is now ready for Phase 4.1 implementation:
+
+1. **UpdateManager Design**
+   - Query Forgejo Releases API: `GET /api/v1/repos/HIM-public/webdrop-bridge/releases/latest`
+   - Parse release assets (exe + checksum)
+   - Download latest executable
+   - Verify SHA256 checksum
+   - Replace current executable
+   - Restart application
+
+2. **Example Integration Code**
+   ```python
+   from src.webdrop_bridge.core.update_manager import UpdateManager
+   
+   manager = UpdateManager(
+       repo_url="https://git.him-tools.de/HIM-public/webdrop-bridge",
+       current_version="0.0.2"
+   )
+   
+   if manager.update_available():
+       manager.download_and_install()
+       manager.restart_app()
+   ```
+
+3. **Forgejo API Endpoint**
+   ```
+   GET https://git.him-tools.de/api/v1/repos/HIM-public/webdrop-bridge/releases/latest
+   
+   Response:
+   {
+       "id": 1,
+       "tag_name": "v0.0.2",
+       "name": "Release 0.0.2",
+       "body": "...",
+       "assets": [
+           {
+               "id": 1,
+               "name": "WebDropBridge.exe",
+               "browser_download_url": "https://git.him-tools.de/..."
+           },
+           {
+               "id": 2,
+               "name": "WebDropBridge.exe.sha256",
+               "browser_download_url": "https://git.him-tools.de/..."
+           }
+       ]
+   }
+   ```
+   # - Settings accessible
+   # - Drag-and-drop works
+   ```
+
+2. **macOS Build Testing** (requires macOS machine)
+   ```bash
+   bash build/scripts/build_macos.sh
+   # Should create: build/dist/macos/WebDropBridge.dmg
+   ```
+
+3. **Optional: Create MSI Installer**
+   ```bash
+   # Install WiX Toolset first
+   python build/scripts/build_windows.py --msi
+   # Output: WebDropBridge-Setup.exe
+   ```
+
+### Deferred Tasks
+
+4. **GitHub Actions CI/CD Pipeline** (`.github/workflows/build.yml`)
+   - Automated Windows builds on release tag
+   - macOS builds on release tag
+   - Checksum generation
+   - Upload to releases
+
+5. **Code Signing & Notarization**
+   - Windows: Requires code signing certificate
+   - macOS: Requires Apple Developer ID and notarization credentials
+
+---
+
+## Configuration Files Added
+
+### For Windows Builds
+```python
+# build/scripts/build_windows.py
+class WindowsBuilder:
+    def __init__(self, project_root: Path):
+        self.project_root = project_root
+        self.build_dir = project_root / "build"
+        ...
+```
+
+### For macOS Builds
+```bash
+# build/scripts/build_macos.sh
+PROJECT_ROOT="$(dirname "$(dirname "$( cd "$(dirname "${BASH_SOURCE[0]}")" && pwd )")")"
+APP_NAME="WebDropBridge"
+DMG_NAME="WebDropBridge.dmg"
+```
+
+### PyInstaller Configuration
+```python
+# build/webdrop_bridge.spec
+SPECPATH = os.path.dirname(os.path.abspath(spec_file))
+project_root = os.path.dirname(SPECPATH)
+
+a = Analysis(
+    [os.path.join(project_root, 'src/webdrop_bridge/main.py')],
+    ...
+    datas=[
+        (os.path.join(project_root, 'webapp'), 'webapp'),
+        (os.path.join(project_root, 'resources'), 'resources'),
+    ],
+)
+```
+
+---
+
+## Technical Decisions & Rationale
+
+### 1. PyInstaller Spec File (Not CLI Arguments)
+- **Decision**: Use .spec file instead of CLI args
+- **Rationale**: Better cross-platform compatibility, easier to maintain, supports complex bundling
+- **Result**: Unified spec works for both Windows and macOS
+
+### 2. Separate Build Scripts (Windows Python, macOS Bash)
+- **Decision**: Python for Windows, Bash for macOS
+- **Rationale**: Windows Python is most portable, macOS scripts integrate better with shell tools
+- **Result**: Platform-native experience, easier CI/CD integration
+
+### 3. Large Executable Size (195.66 MB)
+- **Expected**: Yes, includes:
+  - Python runtime (~50 MB)
+  - PySide6/Qt6 libraries (~80 MB)
+  - Embedded Chromium browser (~50 MB)
+  - Application code and resources (~15 MB)
+- **Mitigation**: Users get single-file download, no external dependencies
+
+### 4. Cross-Platform Data File Bundling
+- **Decision**: Include webapp/ and resources/ in executables
+- **Rationale**: Self-contained distribution, no external file dependencies
+- **Result**: Users can place executable anywhere, always works
+
+---
+
+## Known Limitations & Future Work
+
+### Windows
+- [ ] MSI installer requires WiX Toolset installation on build machine
+- [ ] Code signing requires code signing certificate
+- [ ] No automatic updater yet (Phase 4.1)
+
+### macOS
+- [ ] build_macos.sh script is implemented but untested (no macOS machine in workflow)
+- [ ] Code signing requires macOS machine and certificate
+- [ ] Notarization requires Apple Developer account
+- [ ] Professional DMG requires create-dmg tool installation
+
+### General
+- [ ] CI/CD pipeline not yet implemented
+- [ ] Auto-update system not yet implemented (Phase 4.1)
+- [ ] Icon files not yet created (resources/icons/app.ico, app.icns)
+
+---
+
+## How to Use These Build Scripts
+
+### Quick Start
+
+```bash
+# Windows only - build executable
+cd "c:\Development\VS Code Projects\webdrop_bridge"
+python build/scripts/build_windows.py
+
+# Windows - create MSI (requires WiX)
+python build/scripts/build_windows.py --msi
+
+# macOS only - create .app and DMG
+bash build/scripts/build_macos.sh
+
+# macOS - with code signing
+bash build/scripts/build_macos.sh --sign
+```
+
+### Output Locations
+
+Windows:
+- Executable: `build/dist/windows/WebDropBridge.exe`
+- MSI: `build/dist/windows/WebDropBridge-Setup.exe` (if --msi used)
+
+macOS:
+- App Bundle: `build/dist/macos/WebDropBridge.app`
+- DMG: `build/dist/macos/WebDropBridge.dmg`
+
+---
+
+## Environment Setup
+
+### Windows Build Machine

+# Update Feature Fixes - Final Summary
+
+## Problem Identified
+The update feature was causing the application to hang indefinitely when clicked. The issue had two components:
+
+1. **UI Thread Blocking**: The original code was running download operations synchronously on the UI thread
+2. **Network Timeout Issues**: Even with timeouts set, the socket-level network calls would hang indefinitely if the server didn't respond
+
+## Solutions Implemented
+
+### 1. Background Threading (First Fix)
+- Created `UpdateDownloadWorker` class to run download operations in a background thread
+- Moved blocking network calls off the UI thread
+- This prevents the UI from freezing while waiting for network operations
+
+### 2. Aggressive Timeout Strategy (Second Fix)
+Applied timeouts at multiple levels to ensure the app never hangs:
+
+#### A. Socket-Level Timeout (Most Important)
+- **File**: `src/webdrop_bridge/core/updater.py`
+- Reduced `urlopen()` timeout from 10 seconds to **5 seconds**
+- This is the first line of defense against hanging socket connections
+- Applied in `_fetch_release()` method
+
+#### B. Asyncio-Level Timeout
+- **File**: `src/webdrop_bridge/ui/main_window.py` and `src/webdrop_bridge/core/updater.py`
+- `UpdateCheckWorker`: 10-second timeout on entire check operation
+- `UpdateDownloadWorker`: 300-second timeout on download, 30-second on verification
+- `check_for_updates()`: 8-second timeout on async executor
+- These catch any remaining hangs in the asyncio operations
+
+#### C. Qt-Level Timeout (Final Safety Net)
+- **File**: `src/webdrop_bridge/ui/main_window.py`
+- Update check: **30-second QTimer** safety timeout (`_run_async_check()`)
+- Download: **10-minute QTimer** safety timeout (`_perform_update_async()`)
+- If nothing else works, Qt's event loop will forcefully close the operation
+
+### 3. Error Handling Improvements
+- Added proper exception handling for `asyncio.TimeoutError`
+- Better logging to identify where hangs occur
+- User-friendly error messages like "no server response" or "Operation timed out"
+- Graceful degradation: operations fail fast instead of hanging
+
+## Timeout Hierarchy (in seconds)

+## Files Modified
+1. **src/webdrop_bridge/ui/main_window.py**
+   - Updated `UpdateCheckWorker.run()` with timeout handling
+   - Updated `UpdateDownloadWorker.run()` with timeout handling
+   - Added QTimer safety timeouts in `_run_async_check()` and `_perform_update_async()`
+   - Proper event loop cleanup in finally blocks
+
+2. **src/webdrop_bridge/core/updater.py**
+   - Reduced socket timeout in `_fetch_release()` from 10s to 5s
+   - Added timeout to `check_for_updates()` async operation
+   - Added timeout to `download_update()` async operation
+   - Added timeout to `verify_checksum()` async operation
+   - Better error logging with exception types
+
+## Testing
+- All 7 integration tests pass
+- Timeout verification script confirms all timeout mechanisms are in place
+- No syntax errors in modified code
+
+## Result
+The application will no longer hang indefinitely when checking for or downloading updates. Instead:
+- Operations timeout quickly (5-30 seconds depending on operation type)
+- User gets clear feedback about what went wrong
+- User can retry or cancel without force-killing the app
+- Background threads are properly cleaned up to avoid resource leaks

+# Simplified Versioning System
+
+## Problem Solved
+
+Previously, the application version had to be manually updated in **multiple places**:
+1. `src/webdrop_bridge/__init__.py` - source of truth
+2. `pyproject.toml` - package version
+3. `.env.example` - environment example
+4. Run `scripts/sync_version.py` - manual sync step
+
+This was error-prone and tedious.
+
+## Solution: Single Source of Truth
+
+The version is now defined **only in one place**:
+
+```python
+# src/webdrop_bridge/__init__.py
+__version__ = "1.0.0"
+```
+
+All other components automatically read from this single source.
+
+## How It Works
+
+### 1. **pyproject.toml** (Automatic)
+```toml
+[tool.setuptools.dynamic]
+version = {attr = "webdrop_bridge.__version__"}
+
+[project]
+name = "webdrop-bridge"
+dynamic = ["version"]  # Reads from __init__.py
+```
+
+When you build the package, setuptools automatically extracts the version from `__init__.py`.
+
+### 2. **config.py** (Automatic - with ENV override)
+```python
+# Lazy import to avoid circular imports
+if not os.getenv("APP_VERSION"):
+    from webdrop_bridge import __version__
+    app_version = __version__
+else:
+    app_version = os.getenv("APP_VERSION")
+```
+
+The config automatically reads from `__init__.py`, but can be overridden with the `APP_VERSION` environment variable if needed.
+
+### 3. **sync_version.py** (Simplified)
+The script now only handles:
+- Updating `__init__.py` with a new version
+- Updating `CHANGELOG.md` with a new version header
+- Optional: updating `.env.example` if it explicitly sets `APP_VERSION`
+
+It **no longer** needs to manually sync pyproject.toml or config defaults.
+
+## Workflow
+
+### To Release a New Version
+
+**Option 1: Simple (Recommended)**
+```bash
+# Edit only one file
+# src/webdrop_bridge/__init__.py:
+__version__ = "1.1.0"  # Change this
+
+# Then run sync script to update changelog
+python scripts/sync_version.py
+```
+
+**Option 2: Using the Sync Script**
+```bash
+python scripts/sync_version.py --version 1.1.0
+```
+
+The script will:
+- ✅ Update `__init__.py`
+- ✅ Update `CHANGELOG.md`
+- ✅ (Optional) Update `.env.example` if it has `APP_VERSION=`
+
+### What Happens Automatically
+
+When you run your application:
+1. Config loads and checks environment for `APP_VERSION`
+2. If not set, it imports `__version__` from `__init__.py`
+3. The version is displayed in the UI
+4. Update checks use the correct version
+
+When you build with `pip install`:
+1. setuptools reads `__version__` from `__init__.py`
+2. Package metadata is set automatically
+3. No manual sync needed
+
+## Verification
+
+To verify the version is correctly propagated:
+
+```bash
+# Check __init__.py
+python -c "from webdrop_bridge import __version__; print(__version__)"
+
+# Check config loading
+python -c "from webdrop_bridge.config import Config; c = Config.from_env(); print(c.app_version)"
+
+# Check package metadata (after building)
+pip show webdrop-bridge
+```
+
+All should show the same version.
+
+## Best Practices
+
+1. **Always edit `__init__.py` first** - it's the single source of truth
+2. **Run `sync_version.py` to update changelog** - keeps release notes organized
+3. **Use environment variables only for testing** - don't hardcode overrides
+4. **Run tests after version changes** - config tests verify version loading
+
+## Migration Notes
+
+If you had other places where version was defined:
+- ❌ Remove version from `pyproject.toml` `[project]` section  
+- ✅ Add `dynamic = ["version"]` instead
+- ❌ Don't manually edit `.env.example` for version  
+- ✅ Let `sync_version.py` handle it
+- ❌ Don't hardcode version in config.py defaults
+- ✅ Use lazy import from `__init__.py`
+
+## Testing the System
+
+Run the config tests to verify everything works:
+```bash
+pytest tests/unit/test_config.py -v
+```
+
+All tests should pass, confirming version loading works correctly.
+
+---
+
+**Result**: One place to change, multiple places automatically updated. Simple, clean, professional.

+# WebApp Loading - Issue & Fix Summary
+
+## Problem
+
+When running the Windows executable, the embedded web view displayed:
+
+```
+Error
+Web application file not found: C:\Development\VS Code Projects\webdrop_bridge\file:\webapp\index.html
+```
+
+### Root Causes
+
+1. **Path Resolution Issue**: When the app runs from a bundled executable (PyInstaller), the default webapp path `file:///./webapp/index.html` is resolved relative to the current working directory, not relative to the executable location.
+
+2. **No Fallback UI**: When the webapp file wasn't found, users saw a bare error page instead of a helpful welcome/status page.
+
+## Solution
+
+### 1. Improved Path Resolution (main_window.py)
+
+Enhanced `_load_webapp()` method to:
+- First try the configured path as-is
+- If not found, try relative to the application package root
+- Handle both development mode and PyInstaller bundled mode
+- Work with `file://` URLs and relative paths
+
+```python
+def _load_webapp(self) -> None:
+    if not file_path.exists():
+        # Try relative to application package root
+        # This handles both development and bundled (PyInstaller) modes
+        app_root = Path(__file__).parent.parent.parent.parent
+        relative_path = app_root / webapp_url.lstrip("file:///").lstrip("./")
+        
+        if relative_path.exists():
+            file_path = relative_path
+```
+
+### 2. Beautiful Default Welcome Page
+
+Created `DEFAULT_WELCOME_PAGE` constant with professional UI including:
+- **Status message**: Shows when no web app is configured
+- **Application info**: Name, version, description
+- **Key features**: Drag-drop, validation, cross-platform support
+- **Configuration guide**: Instructions to set up custom webapp
+- **Professional styling**: Gradient background, clean layout, accessibility
+
+### 3. Updated Error Handling
+
+When webapp file is not found, the app now:
+- Shows the welcome page instead of a bare error message
+- Provides clear instructions on how to configure a web app
+- Displays the version number
+- Gives users a professional first impression
+
+## Files Modified
+
+### `src/webdrop_bridge/ui/main_window.py`
+- Added `DEFAULT_WELCOME_PAGE` HTML constant with professional styling
+- Enhanced `_load_webapp()` method with multi-path resolution
+- Added welcome page as fallback for missing/error conditions
+
+### `tests/unit/test_main_window.py`
+- Renamed test: `test_load_nonexistent_file_shows_error` → `test_load_nonexistent_file_shows_welcome_page`
+- Updated assertions to verify welcome page is shown instead of error
+
+## How It Works
+
+### Development Mode
+```
+User runs: python -m webdrop_bridge
+Config: WEBAPP_URL=file:///./webapp/index.html
+Resolution: C:\...\webdrop_bridge\webapp\index.html
+Result: ✅ Loads local webapp from source
+```
+
+### Bundled Executable (PyInstaller)
+```
+User runs: WebDropBridge.exe
+PyInstaller unpacks to: _internal/webapp/
+Resolution logic:
+  1. Try: C:\current\working\dir\webapp\index.html (fails)
+  2. Try: C:\path\to\executable\webapp\index.html (succeeds!)
+Result: ✅ Loads bundled webapp from PyInstaller bundle
+```
+
+### No Webapp Configured
+```
+User runs: WebDropBridge.exe
+No WEBAPP_URL or file not found
+Display: Beautiful welcome page with instructions
+Result: ✅ Professional fallback instead of error
+```
+
+## Testing
+
+All 99 tests pass:
+- ✅ 99 passed in 2.26s
+- ✅ Coverage: 84%
+
+## User Experience
+
+Before:
+```
+Error
+Web application file not found: C:\...\file:\webapp\index.html
+```
+
+After:
+```
+🌉 WebDrop Bridge

+# Create .env file in application directory
+WEBAPP_URL=file:///path/to/your/app.html
+# Or use remote URL
+WEBAPP_URL=http://localhost:3000
+```
+
+## Technical Notes
+
+- CSS selectors escaped with double braces `{{ }}` for `.format()` compatibility
+- Works with both relative paths (`./webapp/`) and absolute paths
+- Handles `file://` URLs and raw file paths
+- Graceful fallback when webapp is missing
+- Professional welcome page generates on-the-fly from template
+

+
+- **Date Fixed**: January 28, 2026
+- **Executable Built**: ✅ WebDropBridge.exe (195.7 MB)
+- **Tests**: ✅ 99/99 passing
+- **Coverage**: ✅ 84%

-# Angular CDK Drag & Drop Analysis - GlobalDAM
-
-## Framework Detection
-
-**Web Application:** Agravity GlobalDAM  
-**Framework:** Angular 19.2.14  
-**Drag & Drop:** Angular CDK (Component Dev Kit)  
-**Styling:** TailwindCSS
-
-## Technical Findings
-
-### 1. Angular CDK Implementation
-
-```html
-<!-- Drag Group (oberste Ebene) -->
-<div cdkdroplistgroup="" aydnd="" class="flex h-full flex-col">
-  
-  <!-- Drop Zone (Collections) -->
-  <div cdkdroplist="" class="cdk-drop-list" id="collectioncsuaaDVNokl0...">
-    
-    <!-- Draggable Element (Asset Card) -->
-    <li cdkdrag="" class="cdk-drag asset-list-item" draggable="false">
-      <img src="./GlobalDAM JRI_files/anPGZszKzgKaSz1SIx2HFgduy" 
-           alt="weiss_ORIGINAL">
-    </li>
-  </div>
-</div>
-```
-
-### 2. Key Observations
-
-#### Native HTML5 Drag ist DEAKTIVIERT
-```html
-draggable="false"
-```
-
-**Bedeutung:**
-- Kein Zugriff auf native `dragstart`, `drag`, `dragend` Events
-- Kein `event.dataTransfer` API verfügbar
-- Angular CDK simuliert Drag & Drop komplett in JavaScript
-- Daten werden NICHT über natives Clipboard/DataTransfer übertragen
-
-#### Angular CDK Direktiven
-- `cdkdroplistgroup` - Gruppiert mehrere Drop-Zonen
-- `cdkdroplist` - Markiert Drop-Bereiche (Collections, Clipboard)
-- `cdkdrag` - Markiert draggbare Elemente (Assets)
-- `cdkdroplistsortingdisabled` - Sortierung deaktiviert
-
-#### Asset Identifikation
-```html
-<!-- Asset ID im Element-ID -->
-<div id="anPGZszKzgKaSz1SIx2HFgduy">
-
-<!-- Asset ID in der Bild-URL -->
-<img src="./GlobalDAM JRI_files/anPGZszKzgKaSz1SIx2HFgduy">
-
-<!-- Asset Name im alt-Attribut -->
-<img alt="weiss_ORIGINAL">
-```
-
-## Impact on WebDrop Bridge
-
-### ❌ Bisheriger Ansatz funktioniert NICHT
-
-Unser aktueller Ansatz basiert auf:
-1. Interception von nativen Drag-Events
-2. Manipulation von `event.dataTransfer.effectAllowed` und `.dropEffect`
-3. Setzen von URLs im DataTransfer
-
-**Das funktioniert NICHT mit Angular CDK**, da:
-- Angular CDK das native Drag & Drop komplett umgeht
-- Keine nativen Events gefeuert werden
-- DataTransfer API nicht verwendet wird
-
-### ✅ Mögliche Lösungsansätze
-
-#### Ansatz 1: JavaScript Injection zur Laufzeit
-Injiziere JavaScript-Code, der Angular CDK Events abfängt:
-
-```javascript
-// Überwache Angular CDK Event-Handler
-document.addEventListener('cdkDragStarted', (event) => {
-  const assetId = event.source.element.nativeElement.id;
-  const assetName = event.source.element.nativeElement.querySelector('img')?.alt;
-  
-  // Sende an Qt WebChannel
-  bridge.handleDragStart(assetId, assetName);
-});
-
-document.addEventListener('cdkDragDropped', (event) => {
-  // Verhindere das Standard-Verhalten
-  event.preventDefault();
-  
-  // Starte nativen Drag von Qt aus
-  bridge.initNativeDrag();
-});
-```
-
-**Vorteile:**
-- ✅ Direkter Zugriff auf Angular CDK Events
-- ✅ Kann Asset-Informationen extrahieren
-- ✅ Kann Drag-Operationen abfangen
-
-**Nachteile:**
-- ⚠️ Erfordert genaue Kenntnis der Angular CDK Internals
-- ⚠️ Könnte bei Angular CDK Updates brechen
-- ⚠️ Komplexer zu implementieren
-
-#### Ansatz 2: DOM Mutation Observer
-Überwache DOM-Änderungen während des Drags:
-
-```javascript
-const observer = new MutationObserver((mutations) => {
-  mutations.forEach((mutation) => {
-    // Suche nach CDK Drag-Elementen mit bestimmten Klassen
-    const dragElement = document.querySelector('.cdk-drag-preview');
-    if (dragElement) {
-      const assetId = dragElement.querySelector('[id^="a"]')?.id;
-      bridge.handleDrag(assetId);
-    }
-  });
-});
-
-observer.observe(document.body, {
-  childList: true,
-  subtree: true,
-  attributes: true,
-  attributeFilter: ['class']
-});
-```
-
-**Vorteile:**
-- ✅ Robuster gegenüber Framework-Updates
-- ✅ Funktioniert mit beliebigen Frameworks
-
-**Nachteile:**
-- ⚠️ Performance-Overhead
-- ⚠️ Kann falsche Positive erzeugen
-
-#### Ansatz 3: Qt WebChannel Bridge mit Custom Events
-Nutze Qt WebChannel, um mit der Angular-Anwendung zu kommunizieren:
-
-```python
-# Python-Seite (Qt)
-class DragBridge(QObject):
-    @Slot(str, str)
-    def onAssetDragStart(self, asset_id: str, asset_name: str):
-        """Called from JavaScript when Angular CDK drag starts."""
-        logger.info(f"Asset drag started: {asset_id} ({asset_name})")
-        self.convert_and_drag(asset_id, asset_name)
-```
-
-```javascript
-// JavaScript-Seite (injiziert via QWebEngineScript)
-new QWebChannel(qt.webChannelTransport, (channel) => {
-  const dragBridge = channel.objects.dragBridge;
-  
-  // Monkey-patch Angular CDK's DragRef
-  const originalStartDraggingSequence = CdkDrag.prototype._startDraggingSequence;
-  CdkDrag.prototype._startDraggingSequence = function(event) {
-    const assetElement = this.element.nativeElement;
-    const assetId = assetElement.id;
-    const assetName = assetElement.querySelector('img')?.alt;
-    
-    // Benachrichtige Qt
-    dragBridge.onAssetDragStart(assetId, assetName);
-    
-    // Rufe original Angular CDK Methode auf
-    return originalStartDraggingSequence.call(this, event);
-  };
-});
-```
-
-**Vorteile:**
-- ✅ Saubere Kommunikation zwischen Qt und Web
-- ✅ Kann Asset-Informationen zuverlässig extrahieren
-- ✅ Typensicher (Qt Signals/Slots)
-
-**Nachteile:**
-- ⚠️ Erfordert Monkey-Patching von Angular CDK
-- ⚠️ Kann bei CDK Updates brechen
-
-#### Ansatz 4: Browser DevTools Protocol (Chrome DevTools)
-Nutze Chrome DevTools Protocol für tiefere Integration:
-
-```python
-from PySide6.QtWebEngineCore import QWebEngineProfile
-
-profile = QWebEngineProfile.defaultProfile()
-profile.setRequestInterceptor(...)
-
-# Intercepte Netzwerk-Requests und injiziere Header
-# Überwache JavaScript-Execution via CDP
-```
-
-**Vorteile:**
-- ✅ Sehr mächtig, kann JavaScript-Execution überwachen
-- ✅ Kann Events auf niedrigerer Ebene abfangen
-
-**Nachteile:**
-- ⚠️ Sehr komplex
-- ⚠️ Erfordert Chrome DevTools Protocol Kenntnisse
-- ⚠️ Performance-Overhead
-
-## Empfohlener Ansatz
-
-### **Ansatz 3: Qt WebChannel Bridge** (BEVORZUGT)
-
-**Begründung:**
-1. ✅ Saubere Architektur mit klarer Trennung
-2. ✅ Typsicher durch Qt Signals/Slots
-3. ✅ Kann Asset-IDs und -Namen zuverlässig extrahieren
-4. ✅ Funktioniert auch wenn Angular CDK interne Änderungen hat
-5. ✅ Ermöglicht bidirektionale Kommunikation
-
-**Implementierungsschritte:**
-
-### Phase 1: Asset-Informationen extrahieren
-1. JavaScript via QWebEngineScript injizieren
-2. Qt WebChannel setuppen
-3. Angular CDK Events überwachen (ohne Monkey-Patching als Test)
-4. Asset-IDs und Namen an Qt senden
-
-### Phase 2: Native Drag initiieren
-1. Bei CDK Drag-Start: Extrahiere Asset-Informationen
-2. Sende Asset-ID an Backend/API
-3. Erhalte lokalen Dateipfad oder Azure Blob URL
-4. Konvertiere zu lokalem Pfad (wie aktuell)
-5. Initiiere nativen Drag mit QDrag
-
-### Phase 3: Drag-Feedback
-1. Zeige Drag-Preview in Qt (optional)
-2. Update Cursor während Drag
-3. Cleanup nach Drag-Ende
-
-## Asset-ID zu Dateipfad Mapping
-
-Die Anwendung verwendet Asset-IDs in mehreren Formaten:
-
-```javascript
-// Asset-ID: anPGZszKzgKaSz1SIx2HFgduy
-
-// Mögliche URL-Konstruktion:
-const assetUrl = `https://dev.agravity.io/api/assets/${assetId}`;
-const downloadUrl = `https://dev.agravity.io/api/assets/${assetId}/download`;
-const blobUrl = `https://static.agravity.io/${workspaceId}/${assetId}/${filename}`;
-```
-
-**Für WebDrop Bridge:**
-- Asset-ID aus DOM extrahieren
-- Asset-Metadaten via API abrufen (falls verfügbar)
-- Blob-URL konstruieren
-- URL Converter nutzen (bereits implementiert!)
-
-## Next Steps
-
-1. **Proof of Concept**: Qt WebChannel mit einfachem Event-Logger
-2. **Asset-ID Extraction**: JavaScript Injection testen
-3. **API Research**: GlobalDAM API untersuchen (Asset-Metadaten)
-4. **Integration**: Mit bestehendem URLConverter verbinden
-5. **Testing**: Mit echten Assets testen
-
-## Hinweise
-
-- Angular CDK Version kann sich unterscheiden - Code muss robust sein
-- Asset-IDs scheinen eindeutig zu sein (Base64-ähnlich)
-- Die Anwendung nutzt Azure Blob Storage (basierend auf bisherigen URLs)
-- Custom Components (`ay-*`) deuten auf eine eigene Component Library hin

-# Drag & Drop Problem Analysis - File Drop + Web App Popup
-
-## Das Kernproblem
-
-**Ziel**: Bei ALT-Drag soll:
-1. ✅ File gedroppt werden (Z:\ Laufwerk) → Native File-Drop
-2. ✅ Web-App Popup erscheinen (Auschecken-Dialog) → Web-App Drop-Event
-
-**Problem**: Diese beiden schließen sich gegenseitig aus:
-- Native File-Drag (von Qt) → Web-App bekommt kein Drop-Event → Kein Popup
-- Browser Text-Drag (von Web-App) → Kein File-Drop → Kein File
-
-## Browser-Sicherheitsbeschränkungen
-
-1. **DataTransfer.files ist read-only**  
-   Wir können keine Files zu einem DataTransfer hinzufügen
-
-2. **Nur EIN Drag zur Zeit möglich**  
-   Wir können keinen parallelen Drag starten
-
-3. **DataTransfer kann nicht erstellt werden**  
-   Wir können kein synthetisches Drop-Event mit Files erzeugen
-
-4. **Cross-Domain Sicherheit**  
-   File-Zugriff ist stark eingeschränkt
-
-## Getestete Ansätze
-
-### ❌ Ansatz 1: DataTransfer erweitern
-**Idee**: Web-App setzt URL, wir fügen Files hinzu  
-**Problem**: DataTransfer.files ist read-only
-
-### ❌ Ansatz 2: Parallele Drags
-**Idee**: Browser-Drag + Qt-Drag gleichzeitig  
-**Problem**: Nur ein Drag zur Zeit möglich
-
-### ❌ Ansatz 3: Synthetisches Drop-Event
-**Idee**: Original Drop abfangen, neues Event mit Files erzeugen  
-**Problem**: DataTransfer.files kann nicht gesetzt werden
-
-### ⚠️ Ansatz 4: Native Drag + Event-Simulation
-**Idee**: Qt Native Drag, dann Web-App Event manuell auslösen  
-**Problem**: Erfordert Kenntnis der exakten Web-App Event-Struktur (Angular CDK)
-
-## 🎯 Praktikable Lösungen
-
-### Lösung A: **Zwei-Phasen Ansatz** (EMPFOHLEN für Testing)
-
-**Phase 1: File-Drop**
-1. ALT-Drag startet
-2. JavaScript erkennt convertible URL
-3. Ruft Qt's `start_file_drag(url)` auf
-4. `preventDefault()` verhindert Browser-Drag
-5. Qt Native Drag läuft
-6. File wird gedroppt ✅
-
-**Phase 2: Popup manuell triggern**
-7. Nach erfolgreichem Drop (via Qt Signal)
-8. JavaScript simuliert den Event/API-Call der das Popup auslöst
-9. Popup erscheint ✅
-
-**Vorteile:**
-- ✅ Funktioniert garantiert für File-Drop
-- ✅ Kontrolle über beide Phasen
-- ✅ Kann debugged werden
-
-**Nachteile:**
-- ⚠️ Erfordert Reverse-Engineering des Popup-Triggers
-- ⚠️ Könnte bei Web-App Updates brechen
-
-**Implementierung:**
-```javascript
-// Phase 1: Standard - File Drag
-document.addEventListener('dragstart', function(e) {
-  if (!e.altKey) return;
-  
-  // Extract URL from DataTransfer
-  var url = e.dataTransfer.getData('text/plain');
-  if (isConvertible(url)) {
-    e.preventDefault();
-    window.bridge.start_file_drag(url);
-  }
-}, true);
-
-// Phase 2: Popup Trigger (nach Drop-Erfolg)
-// Qt ruft auf: window.trigger_checkout_popup(assetId)
-window.trigger_checkout_popup = function(assetId) {
-  // Option 1: Klick auf Checkout-Button simulieren
-  // Option 2: API-Call direkt aufrufen
-  // Option 3: Angular-Event dispatchen
-  
-  // Beispiel: Suche nach Angular-Component und rufe Methode auf
-  var angularComponent = findAngularComponent('ay-asset-card');
-  if (angularComponent) {
-    angularComponent.onCheckout(assetId);
-  }
-};
-```
-
-**TODO für diese Lösung:**
-1. ✅ File-Drag funktioniert bereits
-2. ⏸️ Herausfinden wie Popup ausgelöst wird:
-   - Browser DevTools öffnen
-   - Network-Tab beobachten (API-Call?)
-   - Elements-Tab nutzen (Angular Component?)
-   - Event-Listeners ansehen
-
-### Lösung B: **Gar nichts ändern beim Drag** (FALLBACK)
-
-**Ansatz:**
-1. ALT-Drag läuft normal durch (URL-Text wird gedroppt)
-2. Popup erscheint ✅
-3. Nach Popup-Bestätigung (Auschecken)
-4. **DANN** konvertieren wir die URL und kopieren das File
-
-**Vorteile:**
-- ✅ Web-App funktioniert normal
-- ✅ Kein Popup-Problem
-- ✅ Einfach zu implementieren
-
-**Nachteile:**
-- ⚠️ Kein echter Drag & Drop (nur Copy)
-- ⚠️ User muss zweimal handeln
-
-### Lösung C: **File-Drop via Qt Window Overlay** (EXPERIMENTELL)
-
-**Ansatz:**
-1. Beim ALT-Drag: Start Normal Web-App Drag
-2. Qt erstellt ein transparentes Overlay-Window über dem Browser
-3. Overlay fängt das Drop-Event ab
-4. Qt macht File-Drop
-5. Qt leitet Drop-Koordinaten an Browser weiter
-6. Browser bekommt synthetisches Event (ohne Files, nur Koordinaten)
-7. Popup erscheint
-
-**Vorteile:**
-- ✅ Beide Funktionen potentiell möglich
-- ✅ Keine DataTransfer-Manipulation nötig
-
-**Nachteile:**
-- ⚠️ Sehr komplex
-- ⚠️ Plattform-spezifisch (Windows)
-- ⚠️ Performance-Overhead
-
-## 🔬 Nächste Schritte - Reverse Engineering
-
-Um Lösung A zu implementieren, müssen wir herausfinden:
-
-### 1. Wie wird das Popup ausgelöst?
-
-**Debug-Schritte:**
-```javascript
-// In Browser Console ausführen während ALT-Drag+Drop
-
-// Methode 1: Event-Listener finden
-getEventListeners(document)
-
-// Methode 2: Angular Component finden
-var cards = document.querySelectorAll('ay-asset-card');
-var component = ng.getComponent(cards[0]); // Angular DevTools
-console.log(component);
-
-// Methode 3: Network-Tab
-// Schauen ob API-Call gemacht wird nach Drop
-```
-
-**Erwartete Möglichkeiten:**
-- API-Call zu `/api/assets/{id}/checkout`
-- Angular Event: `cdkDropListDropped`
-- Component-Methode: `onAssetDropped()` oder ähnlich
-- Modal-Service: `ModalService.show('checkout-dialog')`
-
-### 2. Asset-ID extrahieren
-
-Die Asset-ID wird benötigt für den Popup-Trigger:
-
-```javascript
-// Asset-ID ist wahrscheinlich in:

-### 3. Popup programmatisch öffnen
-
-Sobald wir wissen wie, implementieren wir:
-
-```python
-# Python (Qt)
-class DragBridge(QObject):
-    @Slot(str)
-    def on_file_dropped_success(self, local_path: str):
-        """Called after successful file drop."""
-        # Extrahiere Asset-ID aus Pfad oder URL-Mapping
-        asset_id = self.extract_asset_id(local_path)
-        
-        # Trigger Popup via JavaScript
-        js_code = f"window.trigger_checkout_popup('{asset_id}')"
-        self.web_view.page().runJavaScript(js_code)
-```
-
-## ⚡ Quick Win: Debugging aktivieren
-
-Fügen Sie zu **allen** JavaScript-Varianten umfangreiches Logging hinzu:
-
-```javascript
-// In bridge_script.js
-
-// Log ALLE Events
-['dragstart', 'drag', 'dragenter', 'dragover', 'drop', 'dragend'].forEach(function(eventName) {
-  document.addEventListener(eventName, function(e) {
-    console.log('[DEBUG]', eventName, {
-      target: e.target.tagName,
-      dataTransfer: {
-        types: e.dataTransfer.types,
-        effectAllowed: e.dataTransfer.effectAllowed,
-        dropEffect: e.dataTransfer.dropEffect
-      },
-      altKey: e.altKey,
-      coordinates: {x: e.clientX, y: e.clientY}
-    });
-  }, true);
-});
-
-// Log DataTransfer Zugriffe
-Object.defineProperty(DataTransfer.prototype, 'types', {
-  get: function() {
-    var types = this._types || [];
-    console.log('[DEBUG] DataTransfer.types accessed:', types);
-    return types;
-  }
-});
-```
-
-## 📝 Empfehlung
-
-**Sofortige Maßnahmen:**
-
-1. ✅ **Lösung A Phase 1 ist bereits implementiert** (File-Drop funktioniert)
-
-2. 🔍 **Reverse-Engineering durchführen:**
-   - GlobalDAM JRI im Browser öffnen
-   - DevTools öffnen (F12)
-   - ALT-Drag+Drop durchführen
-   - Beobachten:
-     - Network-Tab → API-Calls?
-     - Console → Fehler/Logs?
-     - Angular DevTools → Component-Events?
-
-3. 🛠️ **Popup-Trigger implementieren:**
-   - Sobald bekannt WIE Popup ausgelöst wird
-   - JavaScript-Funktion `trigger_checkout_popup()` erstellen
-   - Von Qt aus nach erfolgreichem Drop aufrufen
-
-4. 🧪 **Testen:**
-   - ALT-Drag eines Assets
-   - File-Drop sollte funktionieren
-   - Popup sollte erscheinen
-
-**Fallback:**
-Falls Reverse-Engineering zu komplex ist → **Lösung B** verwenden (Kein Drag, nur Copy nach Popup-Bestätigung)

+The update feature hang issue has been fixed by:

+
+2. The worker properly handles:
+   - Downloading the update asynchronously
+   - Verifying checksums asynchronously  
+   - Emitting signals for UI updates
+
+3. MainWindow's _perform_update_async() method now:
+   - Creates a background thread for the worker
+   - Connects signals for download complete/failure handlers
+   - Keeps a reference to prevent garbage collection
+   - Properly cleans up threads after completion
+
+Result: The update dialog now displays without freezing the application!
