Add trace log level using debug npm package for flexible verbosity control #30

Copilot · 2025-10-30T18:56:30Z

Adding Trace Level to Verbosity/Tracing Configuration ✅

Summary

Successfully implemented a new "trace" log level for the awf CLI tool using the debug npm package for enhanced debugging and verbosity control, addressing issue #2401. The implementation uses the industry-standard debug package (commonly used in Azure SDKs and many other projects) to provide both simple and advanced logging capabilities.

All Requirements Met

Changes Made

Core Implementation:

Type Definition (src/types.ts): Added 'trace' to LogLevel union type
Logger Class (src/logger.ts):
- Integrated the debug npm package for namespace-based logging
- Created debug instances for different namespaces: awf:trace, awf:debug, awf:info, awf:success, awf:warn, awf:error
- Updated LOG_LEVELS hierarchy: trace=0, debug=1, info=2, warn=3, error=4
- Added trace() method with dimmed console output using chalk.dim()
- Dynamically enables/disables namespaces based on log level
- Maintains backward compatibility with existing --log-level flag
- Supports advanced usage via DEBUG environment variable for fine-grained control
CLI (src/cli.ts):
- Updated --log-level option description to include "trace"
- Updated validation to accept "trace" as valid input
Dependencies (package.json):
- Added debug (^4.4.3) as production dependency
- Added @types/debug (^4.1.12) as dev dependency

Testing:

Created comprehensive test suite (src/logger.test.ts) with 21 tests
Updated existing test (src/cli.test.ts)
Fixed: Removed duplicate test code that caused TypeScript compilation error
✅ All 125 unit tests passing

Documentation:

README.md:
- Added "Verbosity and Logging" section with examples for all 5 log levels
- Added section on using DEBUG environment variable for fine-grained control
- Documented available namespaces and their usage
AGENTS.md: Updated logging descriptions to mention debug package and namespace support
docs/usage.md:
- Updated command-line options to include trace
- Added section on using DEBUG environment variable
- Documented available namespaces
docs/architecture.md: Updated logging description to mention debug package integration

Log Level Hierarchy

trace - All messages (most verbose) - NEW! ⭐
debug - Debug and above
info - Info and above (default)
warn - Warnings and errors
error - Errors only (least verbose)

Benefits of Using `debug` Package

Industry Standard: Widely used package (used in Azure SDKs and many other projects)
Flexible: Supports both simple --log-level flag and advanced DEBUG env var
Namespace-based: Fine-grained control over which logs to enable (e.g., DEBUG=awf:debug,awf:trace)
Timestamps: Automatic timing information between log messages
No Breaking Changes: Maintains full backward compatibility with existing API

Usage Examples

Simple (backward compatible):

sudo awf --log-level debug --allow-domains github.com 'curl https://api.github.com'

Advanced (fine-grained control):

# Enable all awf logs
DEBUG=awf:* sudo -E awf --allow-domains github.com 'curl https://api.github.com'

# Enable only debug and trace
DEBUG=awf:debug,awf:trace sudo -E awf --allow-domains github.com 'curl https://api.github.com'

# Enable only specific namespaces
DEBUG=awf:info,awf:warn,awf:error sudo -E awf --allow-domains github.com 'curl https://api.github.com'

Quality Assurance

✅ All 125 unit tests passing
✅ Build successful
✅ No TypeScript errors
✅ Manual testing confirms debug package integration works correctly
✅ Backward compatible with existing --log-level flag
✅ Code review: No issues found
✅ Security scan (CodeQL): No vulnerabilities detected

Fixes Add field to control verbosity/tracing of awf (related to gh-aw#2401) #14

Original prompt

This section details on the original issue you should resolve

<issue_title>Add field to control verbosity/tracing of awf (related to gh-aw#2401)</issue_title>
<issue_description>Introduce a configuration field to control the verbosity and tracing level for awf, enabling enhanced debugging. This should allow users to adjust the amount of logging or tracing output as needed, similar to the request in the related gh-aw issue githubnext/gh-aw-firewall#2401.

Requirements:

Add a new field in awf configuration for verbosity/tracing.

Allow multiple levels (e.g., error, warning, info, debug, trace).

Document usage with relevant examples.

@copilot can you pick a few scenario from the integration tests and run in the terminal and copy and past the logs to show me how differnet level of verbosity could affect the log for me to review

@copilot can you pick a few scenario from the integration tests and run in the terminal and copy and past the logs to show me how differnet level of verbosity could affect the log for me to review

I've run the command echo "✓ Command executed successfully" with all five log levels. Here are the key differences:

ERROR Level (Least Verbose)

No awf logs shown - only container internal logs. Perfect for production when you only want to see failures.

WARN Level

Same as ERROR for successful operations - would show warnings if any occurred.

INFO Level (Default) - ~12 log lines

Shows key workflow milestones:

[INFO] Allowed domains: github.com
[INFO] Setting up host-level firewall network and iptables rules...
[SUCCESS] Created network 'awf-net' with bridge 'fw-bridge'
[INFO] Setting up host-level iptables rules...
[SUCCESS] Host-level iptables rules configured successfully
[INFO] Generating configuration files...
[INFO] Starting containers...
[SUCCESS] Containers started successfully
[INFO] Executing copilot command...
✓ Command executed successfully
[INFO] Stopping containers...
[SUCCESS] Containers stopped successfully
[SUCCESS] Command completed successfully

DEBUG Level - ~25 log lines

Adds detailed troubleshooting info:

[DEBUG] Configuration: { "allowedDomains": ["github.com"], ... }
[DEBUG] Ensuring firewall network 'awf-net' exists...
[DEBUG] Bridge interface: fw-bridge
[DEBUG] Writing configuration files...
[DEBUG] Squid config written to: /tmp/awf-1761852210810/squid.conf
[DEBUG] Docker Compose config written to: /tmp/awf-1761852210810/docker-compose.yml
[DEBUG] Removing any existing containers with conflicting names...
[DEBUG] Copilot exit code: 0
[DEBUG] Cleaning up host-level iptables rules...
[DEBUG] Cleaning up temporary files...

TRACE Level (Most Verbose) - ~35+ log lines

Shows all internal operations including iptables chain details and network config:

[DEBUG] Creating network 'awf-net' with subnet 172.30.0.0/24...
[DEBUG] Creating dedicated chain 'FW_WRAPPER'...
[DEBUG] Chain 'FW_WRAPPER' already exists, cleaning up...
[DEBUG] Removing reference to FW_WRAPPER from DOCKER-USER line 1
[DEBUG] Inserting rule in DOCKER-USER to jump to FW_WRAPPER for bridge fw-bridge...
[DEBUG] DOCKER-USER chain:
[DEBUG] Chain DOCKER-USER (1 references)
[DEBUG] FW_WRAPPER chain:
[DEBUG] Chain FW_WRAPPER (1 references)
[DEBUG] Docker config written to: /tmp/awf-1761852248654/.docker/config.json
[DEBUG] Copilot logs directory created at: /tmp/awf-1761852248654/copilot-logs
[DEBUG] Squid logs directory created at: /tmp/awf-1761852248654/squid-logs
[DEBUG] Using network config: 172.30.0.0/24 (squid: 172.30.0.10, copilot: 172.30.0.20)

Note: Currently, TRACE level shows more DEBUG messages since the codebase hasn't been instrumented with explicit logger.trace() calls yet. The infrastructure is in place for adding trace-level logging where extremely verbose output is needed (e.g., raw network packets, detailed state transitions).

The full comparison document is available at /tmp/log-level-comparison.md in the test output.

@copilot please fix those

...

Fixed in commit 05e7db8. The issue was duplicate test code in logger.test.ts starting at line 230 that caused a syntax error. Removed the duplicate content and properly closed the test suite. All 125 tests now pass successfully.

@Mossaka i would rather use the "debug" package from npm to implement a very flexible trace . It's a package commonly used already, including in azure sdks

@copilot use "debug" package from npm to implement a very flexible trace

Implemented in commit 62a88c7. The logger now uses the debug npm package for flexible namespace-based logging.

Key features:

Maintains backward compatibility with --log-level flag
Supports advanced usage via DEBUG environment variable (e.g., DEBUG=awf:* sudo -E awf ...)
Namespace-based logging: awf:trace, awf:debug, awf:info, awf:success, awf:warn, awf:error
Includes automatic timestamps between log messages
All 125 tests still passing

Usage examples:

# Simple (existing behavior)
sudo awf --log-level debug --allow-domains github.com 'command'

# Advanced (fine-grained control)
DEBUG=awf:debug,awf:trace sudo -E awf --allow-domains github.com 'command'
