AUR AACS KeyDB Daily Updater

This is an automated tool for maintaining the aacs-keydb-daily package on AUR.

Features

1. Automatic archiving: Archive http://fvonline-db.bplaced.net/export/keydb_eng.zip on web.archive.org
2. SHA256 verification: Compare current AUR package SHA256 with archived file SHA256
3. Automatic generation: If differences are detected, automatically generate AUR package files including:
   • Update version number (based on archive timestamp: YYYYMMDDhhmmss)
   • Update SHA256 hash
   • Replace original link with web.archive.org archive link
   • Generate new .SRCINFO file
   • Commit and push changes to AUR repository
4. Structured logging: Uses the tracing library for hierarchical, structured logging that can be filtered by level and output to stdout, files, or syslog

Configuration

Environment Variables

Create a .env file (optional):

# SSH Key Path for AUR repository access
# Default: ~/.ssh/id_ed25519
SSH_KEY_PATH=~/.ssh/id_ed25519_aur

# Log level configuration (optional)
# Default: info
# Options: trace, debug, info, warn, error
RUST_LOG=info

SSH Key

Ensure you have SSH access to AUR:

• Default path: ~/.ssh/id_ed25519
• Make sure the key is added to your AUR account

Usage

Build

cargo build --release

Run

cargo run

Or run the compiled binary:

./target/release/aur-aacs-keydb

Package Information

• Package name: aacs-keydb-daily
• Description: Contains the Key Database for the AACS Library (Daily Updates)
• Architecture: any
• Dependencies: libaacs
• License: Based on upstream project
• URL: http://fvonline-db.bplaced.net/

Workflow

1. Request archive: Request creation of new archive of http://fvonline-db.bplaced.net/export/keydb_eng.zip on web.archive.org
2. Get archive URL: Retrieve the archive URL from web.archive.org
   • Example: https://web.archive.org/web/20250707095314/http://fvonline-db.bplaced.net/export/keydb_eng.zip
   • Archive URL is used to download the file
   • Archive timestamp is used to generate the version number (YYYYMMDDhhmmss)
3. Download and verify: Download file from archive URL and calculate SHA256
4. Clone/update AUR repo: Clone or update the AUR repository
5. Compare hash: Compare with current AUR package SHA256 (if package exists)
6. Generate files: If different or package doesn't exist, generate PKGBUILD and .SRCINFO
7. Commit and push: Automatically commit and push changes to AUR

Module Structure

• app.rs: Core application logic and workflow orchestration, uses tracing::info for logging
• archive.rs: Web Archive API interaction, handles archive creation and retrieval, uses tracing::info for detailed operation logging
• aur.rs: AUR package management functionality, handles PKGBUILD and .SRCINFO generation
• config.rs: Configuration management, reads environment variables and validates settings
• git.rs: Git operations helper, handles repository cloning/updating and commits, uses tracing::info for operation status
• main.rs: Main application entry point and tracing initialization with hierarchical logging configuration
• error.rs: Custom error type definitions and Result type

Logging

This application uses the tracing library for structured, hierarchical logging:

• Logs are formatted with timestamps and module paths
• Log level can be controlled via environment variables (e.g., RUST_LOG=debug)
• Default log level is INFO
• All modules use consistent logging (no direct println! calls)
• Logs can be redirected to files or syslog by modifying the tracing subscriber in main.rs

Notes

• Current version automatically commits and pushes to AUR
• The tool clones/updates the AUR repository automatically
• Generated files are in /tmp/aur-aacs-keydb-daily/ directory
• Network connection is required (for web.archive.org access)
• SSH key must be configured for AUR access
