Add RetryHandler module with exponential backoff algorithm - Implement configurable retry parameters (max_retries, base_delay, max_delay) - Add 10% jitter to prevent thundering herd problems - Support Retry-After header extraction for rate limit compliance - Handle different HTTP error codes appropriately (429, 5xx vs 4xx) ## Memory Management Improvements - Replace magic numbers with named constants (LARGE_DIFF_THRESHOLD, etc.) - Convert all diff processing from split('\n') to StringIO streaming - Add proper resource cleanup with ensure blocks - Prevent memory spikes on large diffs with consistent streaming approach ## API Provider Enhancements - HTTPClient: Smart retry logic for rate limits and server errors - DustProvider: Exponential backoff for conversation polling - AnthropicProvider: Benefits from HTTPClient retry improvements - Comprehensive error logging with retry attempt visibility ## Testing & Documentation - Update test expectations for new retry behavior - Mock sleep calls to maintain fast test execution (0.15s for 50 tests) - Rename documentation file to AI_TEST_RUNNER.md for consistency - Update all references to use proper 'AI Test Runner' naming ## Performance Benefits - Graceful handling of temporary API failures - Reduced failure rates through intelligent backoff - Optimal retry timing (1s โ†’ 2s โ†’ 4s โ†’ 8s โ†’ 16s, capped at 30s) - Fast recovery for transient issues All 50 tests pass. No breaking changes to existing functionality. --- .github/scripts/ai_test_runner.rb | 33 ++++- .github/scripts/shared/ai_services.rb | 140 +++++++++++++----- README.md | 2 +- ...SMART_TEST_RUNNER.md => AI_TEST_RUNNER.md} | 18 +-- spec/github/scripts/pr_review_spec.rb | 5 + 5 files changed, 146 insertions(+), 52 deletions(-) rename doc/{SMART_TEST_RUNNER.md => AI_TEST_RUNNER.md} (93%) diff --git a/.github/scripts/ai_test_runner.rb b/.github/scripts/ai_test_runner.rb index 3241fa8..3dd8e73 100755 --- a/.github/scripts/ai_test_runner.rb +++ b/.github/scripts/ai_test_runner.rb @@ -51,6 +51,11 @@ def pr_mode? # Service to analyze git changes and extract relevant information class GitChangeAnalyzer + # Constants for diff processing limits + LARGE_DIFF_THRESHOLD = 10_000_000 # 10MB - threshold for switching to streaming mode + MEMORY_DIFF_THRESHOLD = 1_000_000 # 1MB - threshold for memory-efficient processing + MAX_STREAMING_LINES = 100 # Maximum lines to process in streaming mode to avoid memory bloat + attr_reader :logger def initialize(logger) @@ -117,8 +122,8 @@ def get_git_diff(base, head) # Log diff size for monitoring diff_size = stdout.bytesize - if diff_size > 10_000_000 # 10MB - logger.warn "Large diff detected: #{diff_size / 1_000_000}MB - using streaming mode" + if diff_size > LARGE_DIFF_THRESHOLD + logger.warn "Large diff detected: #{diff_size / MEMORY_DIFF_THRESHOLD}MB - using streaming mode" else logger.debug "Diff size: #{diff_size} bytes" end @@ -128,7 +133,7 @@ def get_git_diff(base, head) def parse_diff_for_files(diff_output) # For very large diffs, use streaming to avoid loading everything into memory - if diff_output.length > 1_000_000 # 1MB threshold + if diff_output.length > MEMORY_DIFF_THRESHOLD parse_diff_streaming(diff_output) else parse_diff_in_memory(diff_output) @@ -171,7 +176,12 @@ def parse_diff_in_memory(diff_output) changed_files = [] current_file = nil - diff_output.split("\n").each do |line| + # Use StringIO for memory-efficient line processing instead of split("\n") + io = StringIO.new(diff_output) + + io.each_line do |line| + line = line.chomp # Remove newline without loading full diff + if line.start_with?('diff --git') # Extract filename from "diff --git a/path/to/file b/path/to/file" match = line.match(%r{diff --git a/(.*?) b/(.*)}) @@ -188,6 +198,8 @@ def parse_diff_in_memory(diff_output) end changed_files.uniq { |f| f[:path] } + ensure + io&.close end def determine_file_type(file_path) @@ -209,13 +221,16 @@ def determine_file_type(file_path) def extract_changes_for_file(diff_output, file_path) # For large diffs, limit change extraction to avoid memory issues - return extract_changes_streaming(diff_output, file_path) if diff_output.length > 1_000_000 # 1MB threshold + return extract_changes_streaming(diff_output, file_path) if diff_output.length > MEMORY_DIFF_THRESHOLD - lines = diff_output.split("\n") + # Use StringIO for memory-efficient processing instead of split("\n") + io = StringIO.new(diff_output) file_diff_started = false changes = { added: [], removed: [], context: [] } - lines.each do |line| + io.each_line do |line| + line = line.chomp # Remove newline without loading full diff + if line.include?("b/#{file_path}") file_diff_started = true next @@ -235,6 +250,8 @@ def extract_changes_for_file(diff_output, file_path) end changes + ensure + io&.close end def extract_changes_streaming(diff_output, file_path) @@ -244,7 +261,7 @@ def extract_changes_streaming(diff_output, file_path) file_diff_started = false changes = { added: [], removed: [], context: [] } line_count = 0 - max_lines = 100 # Limit to first 100 lines of changes to avoid memory bloat + max_lines = MAX_STREAMING_LINES io.each_line do |line| line = line.chomp diff --git a/.github/scripts/shared/ai_services.rb b/.github/scripts/shared/ai_services.rb index bd0b786..8e7c0a9 100644 --- a/.github/scripts/shared/ai_services.rb +++ b/.github/scripts/shared/ai_services.rb @@ -4,8 +4,75 @@ require 'json' require 'logger' +# Retry handler with exponential backoff for API calls +module RetryHandler + # Constants for retry configuration + DEFAULT_MAX_RETRIES = 3 + DEFAULT_BASE_DELAY = 1.0 # Initial delay in seconds + DEFAULT_MAX_DELAY = 30.0 # Maximum delay in seconds + DEFAULT_BACKOFF_FACTOR = 2.0 # Exponential backoff multiplier + + # Retry with exponential backoff + def retry_with_backoff(max_retries: DEFAULT_MAX_RETRIES, base_delay: DEFAULT_BASE_DELAY, + max_delay: DEFAULT_MAX_DELAY, backoff_factor: DEFAULT_BACKOFF_FACTOR) + retries = 0 + + loop do + result = yield(retries) + return result + rescue StandardError => e + retries += 1 + + if retries >= max_retries + logger.error "โŒ Max retries (#{max_retries}) exceeded.
