From bfdbf3ce87b320d555b357e114e7c56a461106c3 Mon Sep 17 00:00:00 2001 From: PeerInfinity <163462+PeerInfinity@users.noreply.github.com> Date: Sat, 20 Dec 2025 12:07:35 -0800 Subject: [PATCH 01/11] Add object/function opcode support and heap refactoring MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit adds comprehensive ActionScript 2.0 object and function support: Object System (new files): - object.h/object.c: ASObject and ASArray with reference counting - Property management with ECMA-262 compliant attribute flags - Interface support for ActionScript 2.0 implements keyword ActionScript Opcodes (action.c): - Object opcodes: NewObject, InitObject, TypeOf, InstanceOf, Enumerate, Enumerate2 - Array opcodes: InitArray - Function opcodes: DefineFunction, DefineFunction2, CallFunction, CallMethod - Member access: GetMember, SetMember, DeleteMember - Stack operations: StackSwap, PushDuplicate - Comparison: Equals2, StrictEquals, Greater, Less2 - String operations: StringAdd, StringLength, StringExtract, MBStringLength - Type conversion: ToNumber, ToString, ToInteger - Built-in functions: trace(), getTimer(), random(), etc. Heap Refactoring: - All heap functions now require app_context parameter - HALLOC/FREE/HCALLOC macros for convenient allocation - Virtual memory-based allocation with lazy physical commit - Proper initialization order: heap_init before flashbang_init SWFAppContext Enhancements: - Added heap_inited, heap_full_size, heap_current_size fields - Added frame_count, is_playing, is_dragging, dragged_target - NO_GRAPHICS guards for graphics-specific fields 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- CMakeLists.txt | 1 + include/actionmodern/action.h | 160 +- include/actionmodern/object.h | 180 + include/actionmodern/stackvalue.h | 11 +- include/actionmodern/variables.h | 30 +- include/flashbang/flashbang.h | 19 +- include/libswf/swf.h | 62 +- include/libswf/tag.h | 6 +- include/memory/heap.h | 93 +- src/actionmodern/action.c | 6326 ++++++++++++++++++++++++++++- src/actionmodern/object.c | 845 ++++ src/actionmodern/variables.c | 277 +- src/flashbang/flashbang.c | 159 +- src/libswf/swf.c | 102 +- src/libswf/swf_core.c | 93 +- src/libswf/tag.c | 36 +- src/libswf/tag_stubs.c | 12 +- src/memory/heap.c | 198 +- 18 files changed, 8081 insertions(+), 529 deletions(-) create mode 100644 include/actionmodern/object.h create mode 100644 src/actionmodern/object.c diff --git a/CMakeLists.txt b/CMakeLists.txt index 899e135..850eef3 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -14,6 +14,7 @@ option(NO_GRAPHICS "Build without graphics support (console-only)" OFF) # Core sources (always included) set(CORE_SOURCES ${PROJECT_SOURCE_DIR}/src/actionmodern/action.c + ${PROJECT_SOURCE_DIR}/src/actionmodern/object.c ${PROJECT_SOURCE_DIR}/src/actionmodern/variables.c ${PROJECT_SOURCE_DIR}/src/memory/heap.c ${PROJECT_SOURCE_DIR}/src/utils.c diff --git a/include/actionmodern/action.h b/include/actionmodern/action.h index eb7fff5..ff5da42 100644 --- a/include/actionmodern/action.h +++ b/include/actionmodern/action.h @@ -3,14 +3,50 @@ #include #include #include +#include + +// Forward declarations +typedef struct MovieClip MovieClip;

charset=UTF-8 Content-Transfer-Encoding: 8bit - Revert ActionVar struct to upstream anonymous union API - Revert variables.c to use HALLOC and app_context parameters - Revert heap.h/heap.c to simpler upstream implementation - Add heap_calloc for zeroed memory allocation - Stub MovieClip-related functions not in SWFRecomp's minimal opcode set: actionTargetPath, actionPlay, actionEndDrag, actionSetTarget2, actionGetProperty, actionSetProperty, actionSetTarget, actionStartDrag, actionWaitForFrame, actionWaitForFrame2 - Fix function signatures to match reverted API: getVariable, setVariableWithValue, materializeStringList - Keep object/function opcode implementations needed by SWFRecomp 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- include/actionmodern/action.h | 188 ++--- include/actionmodern/stackvalue.h | 5 +- include/actionmodern/variables.h | 30 +- include/flashbang/flashbang.h | 41 +- include/libswf/swf.h | 54 +- include/memory/heap.h | 84 +- src/actionmodern/action.c | 1301 +++++++++-------------------- src/actionmodern/object.c | 74 +- src/actionmodern/variables.c | 277 ++---- src/flashbang/flashbang.c | 61 +- src/libswf/swf.c | 100 +-- src/libswf/swf_core.c | 93 +-- src/memory/heap.c | 195 +---- 13 files changed, 751 insertions(+), 1752 deletions(-) diff --git a/include/actionmodern/action.h b/include/actionmodern/action.h index db8370d..7d3581c 100644 --- a/include/actionmodern/action.h +++ b/include/actionmodern/action.h @@ -3,50 +3,14 @@ #include #include #include -#include - -// Forward declarations -typedef struct MovieClip MovieClip;
