Squashed commit of the following: [alpha_presentable] Author: John McCardle <mccardle.john@gmail.com> Co-Authored-By: Claude <noreply@anthropic.com> commit dc47f2474c7b2642d368f9772894aed857527807 the UIEntity rant commit 673ca8e1b089ea670257fc04ae1a676ed95a40ed I forget when these tests were written, but I want them in the squash merge commit 70c71565c684fa96e222179271ecb13a156d80ad Fix UI object segfault by switching from managed to manual weakref management The UI types (Frame, Caption, Sprite, Grid, Entity) were using Py_TPFLAGS_MANAGED_WEAKREF while also trying to manually create weakrefs for the PythonObjectCache. This is fundamentally incompatible - when Python manages weakrefs internally, PyWeakref_NewRef() cannot access the weakref list properly, causing segfaults. Changed all UI types to use manual weakref management (like PyTimer): - Restored weakreflist field in all UI type structures - Removed Py_TPFLAGS_MANAGED_WEAKREF from all UI type flags - Added tp_weaklistoffset for all UI types in module initialization - Initialize weakreflist=NULL in tp_new and init methods - Call PyObject_ClearWeakRefs() in dealloc functions This allows the PythonObjectCache to continue working correctly, maintaining Python object identity for C++ objects across the boundary. Fixes segfault when creating UI objects (e.g., Caption, Grid) that was preventing tutorial scripts from running. This is the bulk of the required behavior for Issue #126. that issure isn't ready for closure yet; several other sub-issues left. closes #110 mention issue #109 - resolves some __init__ related nuisances commit 3dce3ec539ae99e32d869007bf3f49d03e4e2f89 Refactor timer system for cleaner architecture and enhanced functionality Major improvements to the timer system: - Unified all timer logic in the Timer class (C++) - Removed PyTimerCallable subclass, now using PyCallable directly - Timer objects are now passed to callbacks as first argument - Added 'once' parameter for one-shot timers that auto-stop - Implemented proper PythonObjectCache integration with weakref support API enhancements: - New callback signature: callback(timer, runtime) instead of just (runtime) - Timer objects expose: name, interval, remaining, paused, active, once properties - Methods: pause(), resume(), cancel(), restart() - Comprehensive documentation with examples - Enhanced repr showing timer state (active/paused/once/remaining time) This cleanup follows the UIEntity/PyUIEntity pattern and makes the timer system more Pythonic while maintaining backward compatibility through the legacy setTimer/delTimer API. closes #121 commit 145834cfc31b8dabc4cb3591b9cb4ed99fc8b964 Implement Python object cache to preserve derived types in collections Add a global cache system that maintains weak references to Python objects, ensuring that derived Python classes maintain their identity when stored in and retrieved from C++ collections. Key changes: - Add PythonObjectCache singleton with serial number system - Each cacheable object (UIDrawable, UIEntity, Timer, Animation) gets unique ID - Cache stores weak references to prevent circular reference memory leaks - Update all UI type definitions to support weak references (Py_TPFLAGS_MANAGED_WEAKREF) - Enable subclassing for all UI types (Py_TPFLAGS_BASETYPE) - Collections check cache before creating new Python wrappers - Register objects in cache during __init__ methods - Clean up cache entries in C++ destructors This ensures that Python code like: ```python class MyFrame(mcrfpy.Frame): def __init__(self): super().__init__() self.custom_data = "preserved" frame = MyFrame() scene.ui.append(frame) retrieved = scene.ui[0] # Same MyFrame instance with custom_data intact ``` Works correctly, with retrieved maintaining the derived type and custom attributes.

The issue was iterator invalidation in AnimationManager::update() when callbacks modified the active animations vector. Changes: - Add deferred animation queue to AnimationManager - New animations created during update are queued and added after - Set isUpdating flag to track when in update loop - Properly handle Animation destructor during callback execution - Add clearCallback() method for safe cleanup scenarios This fixes the "free(): invalid pointer" and "malloc(): unaligned fastbin chunk detected" errors that occurred with rapid animation creation in callbacks. commit eb88c7b3aab3da519db7569106c34f3510b6e963 Add animation completion callbacks (#119) Implement callbacks that fire when animations complete, enabling direct causality between animation end and game state changes. This eliminates race conditions from parallel timer workarounds. - Add optional callback parameter to Animation constructor - Callbacks execute synchronously when animation completes - Proper Python reference counting with GIL safety - Callbacks receive (anim, target) parameters (currently None) - Exception handling prevents crashes from Python errors Example usage: ```python def on_complete(anim, target): player_moving = False anim = mcrfpy.Animation("x", 300.0, 1.0, "easeOut", callback=on_complete) anim.start(player) ``` closes #119 commit 9fb428dd0176a4d7cfad09deb7509d8aa5562868 Update ROADMAP with GitHub issue numbers (#111-#125) Added issue numbers from GitHub tracker to roadmap items: - #111: Grid Click Events Broken in Headless - #112: Object Splitting Bug (Python type preservation) - #113: Batch Operations for Grid - #114: CellView API - #115: SpatialHash Implementation - #116: Dirty Flag System - #117: Memory Pool for Entities - #118: Scene as Drawable - #119: Animation Completion Callbacks - #120: Animation Property Locking - #121: Timer Object System - #122: Parent-Child UI System - #123: Grid Subgrid System - #124: Grid Point Animation - #125: GitHub Issues Automation Also updated existing references: - #101/#110: Constructor standardization - #109: Vector class indexing Note: Tutorial-specific items and Python-implementable features (input queue, collision reservation) are not tracked as engine issues. commit 062e4dadc42833bf5a3559e5d7c4ceb4abb7e9c0 Fix animation segfaults with RAII weak_ptr implementation Resolved two critical segmentation faults in AnimationManager: 1. Race condition when creating multiple animations in timer callbacks 2. Exit crash when animations outlive their target objects Changes: - Replace raw pointers with std::weak_ptr for automatic target invalidation - Add Animation::complete() to jump animations to final value - Add Animation::hasValidTarget() to check if target still exists - Update AnimationManager to auto-remove invalid animations - Add AnimationManager::clear() call to GameEngine::cleanup() - Update Python bindings to pass shared_ptr instead of raw pointers This ensures animations can never reference destroyed objects, following proper RAII principles. Tested with sizzle_reel_final.py and stress tests creating/destroying hundreds of animated objects. commit 98fc49a978ec792ee6096f40fd4e19841b8ec6a3 Directory structure cleanup and organization overhaul 2025-07-15 21:30:49 -04:00			`import mcrfpy`
