Implement comprehensive GitHub API error handling for changelog synchronization #375

Copilot · 2025-09-07T21:00:54Z

Problem

The existing changelog synchronization system had basic error handling that could fail silently or with unclear error messages when encountering GitHub API issues. The system lacked:

Rate limit detection and handling
Authentication verification
Repository accessibility validation
Retry logic for transient failures
Debugging capabilities
Options for regenerating existing changelog files

Solution

This PR implements a comprehensive GitHub API error handling infrastructure that provides robust, reliable interaction with GitHub APIs.

Key Features

🔧 Enhanced Error Handling

Categorized error types with specific error codes (authentication, rate limits, network, etc.)
Actionable troubleshooting suggestions for each error type
Graceful degradation when some repositories are inaccessible

⚡ Rate Limiting Management

Automatic detection of API rate limits with intelligent waiting
Preservation of API quota by checking limits before requests
Configurable rate limit buffer to prevent hitting limits

🔒 Authentication & Repository Validation

Pre-flight authentication checks using GitHub CLI
Repository accessibility validation before processing
Clear error messages for permission issues

🔄 Retry Logic & Resilience

Exponential backoff retry mechanism for transient failures
Configurable retry attempts (default: 3)
Network error detection and handling

📝 Enhanced Logging & Debugging

Multiple logging levels: DEBUG, VERBOSE, INFO, WARN, ERROR
Timestamped log entries for better troubleshooting
Environment variable controls for log verbosity

⚙️ Force Regeneration Capability

--force-regenerate flag to overwrite existing changelog files
FORCE_REGENERATE_CHANGELOGS environment variable support
Prevents accidental overwrites while enabling intentional updates

Files Modified/Created

scripts/github_api_utils.sh - New shared utility with comprehensive API functions
scripts/process_single_release.sh - Enhanced with force regeneration and better logging
scripts/catch_up_releases.sh - Improved CLI options and error tracking
.github/workflows/sync-bluefin-releases.yml - Updated to use enhanced error handling
GITHUB_API_ERROR_HANDLING.md - Comprehensive documentation

Usage Examples

# Catch up on releases with force regeneration
./scripts/catch_up_releases.sh 7 --force-regenerate --debug

# Process release with enhanced error handling
./scripts/process_single_release.sh "ublue-os/bluefin" "stable-20250907" "..." --force-regenerate

# Run with verbose logging
export VERBOSE_MODE=true
./scripts/catch_up_releases.sh --verbose

Error Handling Examples

Authentication Issues:

[ERROR] GitHub CLI is not authenticated
[INFO] 💡 Troubleshooting suggestions:
  • Run 'gh auth login' to authenticate with GitHub
  • Set GH_TOKEN environment variable with a valid token

Rate Limiting:

[WARN] ⚠️ Rate limit low: 8 requests remaining
[WARN] ⏰ Rate limit exceeded. Waiting 1847s for reset...

Repository Access:

[ERROR] ❌ Repository not found: invalid-repo
[INFO] 💡 Troubleshooting suggestions:
  • Verify repository name is correct
  • Check if repository exists and is accessible

Testing

All changes have been thoroughly tested with:

✅ Syntax validation for all scripts and workflows
✅ Function testing for error handling capabilities
✅ Command line interface validation
✅ Documentation completeness verification
✅ Build system compatibility confirmation

The enhanced system is production-ready and provides robust, reliable GitHub API interaction with comprehensive error handling for the changelog synchronization workflow.

scripts/github_api_utils.sh

+        # Calculate wait time if we're out of requests
+        if [[ "$core_remaining" -eq 0 ]]; then
+            local current_time wait_time
+            current_time=$(date +%s)


The arithmetic expansion could fail if core_reset_time or current_time contain non-numeric values. Add validation to ensure both variables are valid integers before performing arithmetic operations.

Suggested change

current_time=$(date +%s)

current_time=$(date +%s)

# Validate that core_reset_time and current_time are integers

if ! [[ "$core_reset_time" =~ ^[0-9]+$ && "$current_time" =~ ^[0-9]+$ ]]; then

log_error "Invalid reset time or current time: core_reset_time='$core_reset_time', current_time='$current_time'"

return $ERROR_RATE_LIMIT

+        if [[ $attempt -lt $max_retries ]]; then

+            sleep "$current_delay"
+            current_delay=$((current_delay * 2))  # Exponential backoff


The exponential backoff calculation could result in extremely large delay values that exceed reasonable limits. Consider adding a maximum delay cap to prevent indefinite waiting.

Suggested change

current_delay=$((current_delay * 2)) # Exponential backoff

current_delay=$((current_delay * 2)) # Exponential backoff

if (( current_delay > MAX_WAIT_TIME )); then

current_delay=$MAX_WAIT_TIME

+FORCE_REGENERATE="false"
+
+# Check for force regenerate flag
+if [[ "$9" == "--force-regenerate" ]] || [[ "$FORCE_REGENERATE_CHANGELOGS" == "true" ]]; then


Using positional parameter $9 for flag detection is fragile and makes the script difficult to extend with additional parameters. Consider implementing proper argument parsing with a while loop to handle flags in any position.

+        [0-9]*)
+            # Skip numeric argument (already processed as DAYS_BACK)
+            shift


The numeric argument handling assumes the first numeric argument is always DAYS_BACK, but this logic doesn't update DAYS_BACK if it appears later in the argument list. This could lead to inconsistent behavior when arguments are reordered.

scripts/github_api_utils.sh

+        reset_date=$(date -d "@$core_reset_time" 2>/dev/null || date -r "$core_reset_time" 2>/dev/null || echo "unknown")


The fallback chain for date formatting uses different command formats for different systems but doesn't validate that core_reset_time is a valid Unix timestamp before using it. Consider adding validation to ensure it's numeric before attempting date conversion.

Suggested change

reset_date=$(date -d "@$core_reset_time" 2>/dev/null || date -r "$core_reset_time" 2>/dev/null || echo "unknown")

if [[ "$core_reset_time" =~ ^[0-9]+$ ]]; then

reset_date=$(date -d "@$core_reset_time" 2>/dev/null || date -r "$core_reset_time" 2>/dev/null || echo "unknown")
