From 6465abc977d01b3dace6a6d5f9e0545f044d444d Mon Sep 17 00:00:00 2001 From: Chuck <33324927+ChuckBuilds@users.noreply.github.com> Date: Mon, 22 Sep 2025 10:44:23 -0400 Subject: [PATCH 01/14] Fix leaderboard timing issues with comprehensive improvements - Add maximum display time cap (120s) to prevent hanging - Implement dynamic scroll speed tracking with runtime measurements - Simplify complex timing logic that was causing hangs - Add enhanced progress tracking and logging - Add configurable safety buffer (10s) - Update config template with new timing options - Add comprehensive test suite for timing logic Fixes the 30-second hanging issue reported in PR #53 by providing multiple layers of protection against time overestimation. --- config/config.template.json | 2 + src/leaderboard_manager.py | 114 ++++++++++++++++++--------- test_leaderboard_timing.py | 152 ++++++++++++++++++++++++++++++++++++ test_timing_logic.py | 107 +++++++++++++++++++++++++ 4 files changed, 339 insertions(+), 36 deletions(-) create mode 100644 test_leaderboard_timing.py create mode 100644 test_timing_logic.py diff --git a/config/config.template.json b/config/config.template.json index 643dec3da..463ad6c76 100644 --- a/config/config.template.json +++ b/config/config.template.json @@ -204,6 +204,8 @@ "min_duration": 45, "max_duration": 600, "duration_buffer": 0.1, + "max_display_time": 120, + "safety_buffer": 10, "background_service": { "enabled": true, "max_workers": 3, diff --git a/src/leaderboard_manager.py b/src/leaderboard_manager.py index 872b845ef..282863690 100644 --- a/src/leaderboard_manager.py +++ b/src/leaderboard_manager.py @@ -52,6 +52,15 @@ def __init__(self, config: Dict[str, Any], display_manager: DisplayManager): self.dynamic_duration = 60 # Default duration in seconds self.total_scroll_width = 0 # Track total width for dynamic duration calculation + # Safety timeout settings + self.max_display_time = self.leaderboard_config.get('max_display_time', 120) # 2 minutes maximum + self.safety_buffer = self.leaderboard_config.get('safety_buffer', 10) # 10 seconds safety buffer + + # Dynamic scroll speed tracking + self.actual_scroll_speed = 54.2 # Default from logs, will be updated dynamically + self.scroll_measurements = [] # Track recent scroll speed measurements + self.max_measurements = 10 # Keep last 10 measurements for averaging + # Initialize managers self.cache_manager = CacheManager() # Store reference to config instead of creating new ConfigManager @@ -80,6 +89,10 @@ def __init__(self, config: Dict[str, Any], display_manager: DisplayManager): self.leaderboard_image = None # This will hold the single, wide image self.last_display_time = 0 + # Progress tracking + self.expected_completion_time = 0 + self.last_progress_log_time = 0 + # Font setup self.fonts = self._load_fonts() @@ -1115,6 +1128,26 @@ def _create_leaderboard_image(self) -> None: logger.error(f"Error creating leaderboard image: {e}") self.leaderboard_image = None + def update_scroll_speed_measurement(self, distance_pixels: float, time_seconds: float): + """Update the actual scroll speed measurement for more accurate timing""" + if time_seconds > 0 and distance_pixels > 0: + current_speed = distance_pixels / time_seconds + + # Add to measurements list + self.scroll_measurements.append(current_speed) + + # Keep only the most recent measurements + if len(self.scroll_measurements) > self.max_measurements: + self.scroll_measurements.pop(0) + + # Calculate average speed from recent measurements + if len(self.scroll_measurements) >= 3: # Need at least 3 measurements for stability + self.actual_scroll_speed = sum(self.scroll_measurements) / len(self.scroll_measurements) + logger.debug(f"Updated scroll speed: {self.actual_scroll_speed:.1f} px/s (from {len(self.scroll_measurements)} measurements)") + + # Ensure reasonable bounds (10-200 px/s) + self.actual_scroll_speed = max(10, min(200, self.actual_scroll_speed)) + def calculate_dynamic_duration(self): """Calculate the exact time needed to display all leaderboard content""" logger.info(f"Calculating dynamic duration -
