- Purpose: C++ Kraken bridge and page/context pool management with UI and Dart method integration. Engine-specific includes included when KRAKEN_JSC_ENGINE or KRAKEN_QUICK_JS_ENGINE are defined.

- Key platform macros (SYSTEM_NAME):
  - windows, android, linux, ios, macos, unknown (determined at compile time).

- Global/state:
  - inited (atomic), poolIndex (atomic), maxPoolSize (int), screen (NativeScreen), uiThreadId.

- Core API surface (notable functions):
  - initJSPagePool(poolSize): captures UI thread, disposes existing pages if reinitializing, allocates pageContextPool[0..], initializes pageContextPool[0] with KrakenPage(0, printError), sets inited and maxPoolSize.
  - disposeAllPages: disposes pages up to poolIndex, resets poolIndex and inited.
  - disposePage(contextId): deletes a KrakenPage and clears slot.
  - allocateNewPage(targetContextId): assigns a new page either at given id or next index; asserts target slot is free; returns contextId.
  - getPage(contextId): returns page if valid, else null.
  - checkPage(contextId) / checkPage(contextId, context): validity checks (inited, bounds, non-null, optional context match).
  - evaluateScripts(contextId, code, bundleFilename, startLine): run script in page context.
  - evaluateQuickjsByteCode(contextId, bytes, byteLen): run bytecode.
  - parseHTML(contextId, code, length): parse HTML content.
  - reloadJsContext(contextId): recreate pageContextPool[contextId].
  - invokeModuleEvent(contextId, moduleName, eventType, event, extra): dispatch module event.
  - registerDartMethods(methodBytes, length): register methods with Dart side.
  - createScreen(width, height): populate and return a NativeScreen.
  - getKrakenInfo(): singleton KrakenInfo with app_name "Kraken", app_revision APP_REV, app_version APP_VERSION, system_name SYSTEM_NAME.
  - setConsoleMessageHandler(handler): set KrakenPage::consoleMessageHandler.
  - dispatchUITask(contextId, context, callback): run callback on UI thread.
  - flushUITask(contextId): flush UI tasks.
  - registerUITask(contextId, task, data): enqueue UI task.
  - flushUICommandCallback(): flush UI command callbacks.
  - getUICommandItems(contextId) / getUICommandItemSize(contextId) / clearUICommandItems(contextId): access/size/clear UI command buffer via page context.
  - registerContextDisposedCallbacks(contextId, task, data): placeholder (no-op logic shown).
  - registerPluginByteCode(bytes, length, pluginName): store plugin bytecode in KrakenPage::pluginByteCode[pluginName].
  - profileModeEnabled(): returns 1 if ENABLE_PROFILE is defined, else 0.
  - NativeString::clone / NativeString::free: clone duplicates length and string; free deletes string array.

- Data/config details:
  - APP_REV and APP_VERSION are build-time macros; APP_NAME defaults to "Kraken".
  - SYSTEM_NAME populated using compile-time platform checks; values map to Windows/Android/Linux/iOS/macOS or "unknown".
  - Optional engine-specific includes:
    - KRAKEN_JSC_ENGINE: includes bindings/jsc/KOM/performance.h and bridge_jsc.h.
    - KRAKEN_QUICK_JS_ENGINE: includes page.h.

- Files referenced (example paths):
  - kraken_bridge.h, dart_methods.h
  - foundation/inspector_task_queue.h, foundation/logging.h, foundation/ui_task_queue.h
  - bindings/jsc/KOM/performance.h (when JSC engine)
  - page.h (when QuickJS engine)

- Notable behavior/notes:
  - Errors/logging: printError(contextId, errmsg) forwards to Dart onJsError/onJsLog if set, and logs via KRAKEN_LOG(ERROR).
  - Page pool uses KrakenPage::pageContextPool array and supports hot-restart disposal.
  - Console and UI task handling wired to thread checks and queues.
  - No explicit runtime errors shown; actionable items revolve around pool management, page lifecycle, and UI/Dart integration.

- File: KRAKEN_BRIDGE_EXPORT_H (header guard used)
- Includes:
  - <cstdint>, <thread>
  - "dart_methods.h", "kraken_foundation.h"
  - Conditional: "kraken_bridge_jsc.h" if KRAKEN_JSC_ENGINE is defined
- Macros:
  - KRAKEN_EXPORT_C: extern "C" with default visibility and used attribute
  - KRAKEN_EXPORT: default visibility
- Types and structs:
  - std::thread::id getUIThreadId();
  - NativeString: { const uint16_t* string; uint32_t length; clone(); free(); }
  - NativeByteCode: { uint8_t* bytes; int32_t length; }
  - KrakenInfo: { const char* app_name; app_version; app_revision; system_name; }
  - NativeScreen: { double width; double height; }
  - enum UICommand: createElement, createTextNode, createComment, disposeEventTarget, addEvent, removeNode, insertAdjacentNode, setStyle, setAttribute, removeAttribute, cloneNode, removeEvent, createDocumentFragment
  - UICommandItem (KRAKEN_EXPORT): fields and constructors
    - int32_t type, id
    - int32_t args_01_length, args_02_length
    - int64_t string_01, string_02
    - int64_t nativePtr
- Function types:
  - typedef void (*Task)(void*)
  - typedef void (*ConsoleMessageHandler)(void* ctx, const std::string& message, int logLevel)

  - void initJSPagePool(int poolSize);
  - void disposePage(int32_t contextId);
  - int32_t allocateNewPage(int32_t targetContextId);
  - void* getPage(int32_t contextId);
  - bool checkPage(int32_t contextId);
  - bool checkPage(int32_t contextId, void* context);
  - void evaluateScripts(int32_t contextId, NativeString* code, const char* bundleFilename, int startLine);
  - void evaluateQuickjsByteCode(int32_t contextId, uint8_t* bytes, int32_t byteLen);
  - void parseHTML(int32_t contextId, const char* code, int32_t length);
  - void reloadJsContext(int32_t contextId);
  - void invokeModuleEvent(int32_t contextId, NativeString* module, const char* eventType, void* event, NativeString* extra);
  - void registerDartMethods(uint64_t* methodBytes, int32_t length);
  - NativeScreen* createScreen(double width, double height);
  - KrakenInfo* getKrakenInfo();
  - void dispatchUITask(int32_t contextId, void* context, void* callback);
  - void flushUITask(int32_t contextId);
  - void registerUITask(int32_t contextId, Task task, void* data);
  - void flushUICommandCallback();
  - UICommandItem* getUICommandItems(int32_t contextId);
  - int64_t getUICommandItemSize(int32_t contextId);
  - void clearUICommandItems(int32_t contextId);
  - void registerContextDisposedCallbacks(int32_t contextId, Task task, void* data);
  - void registerPluginByteCode(uint8_t* bytes, int32_t length, const char* pluginName);
  - int32_t profileModeEnabled();
  - void setConsoleMessageHandler(ConsoleMessageHandler handler);

- Notes:
  - The header exposes a C API for Kraken JS bridge functionality, including page/context management, script evaluation, HTML parsing, UI task dispatch, and plugin/bytecode support.
  - Conditional inclusion allows integration with the JSC engine via kraken_bridge_jsc.h when KRAKEN_JSC_ENGINE is defined.

Summary:

- File/role: C++ header kraken/js/qjs_bridge.h (header guard KRAKEN_JS_QJS_BRIDGE_H_). Defines KrakenPage, the container for all JS objects created by a Kraken Flutter widget, using QuickJS.

- Includes: <quickjs/quickjs.h>, bindings/qjs/executing_context.h, bindings/qjs/html_parser.h, include/kraken_bridge.h.

- Namespace: kraken

- Core type/alias:
  - typedef JSBridgeDisposeCallback = void (*)(KrakenPage* bridge)

- KrakenPage class (kraken::KrakenPage)
  - Static members:
    - KrakenPage** pageContextPool
    - ConsoleMessageHandler consoleMessageHandler
    - static std::unordered_map<std::string, NativeByteCode> pluginByteCode
  - Constructors/Destructor:
    - KrakenPage() = delete
    - KrakenPage(int32_t jsContext, const JSExceptionHandler& handler)
    - ~KrakenPage()
  - Public API:
    - evaluateScript overloads:
      - void evaluateScript(const NativeString* script, const char* url, int startLine)
      - void evaluateScript(const uint16_t* script, size_t length, const char* url, int startLine)
      - void evaluateScript(const char* script, size_t length, const char* url, int startLine)
    - bool parseHTML(const char* code, size_t length)
    - uint8_t* dumpByteCode(const char* script, size_t length, const char* url, size_t* byteLength)
    - void evaluateByteCode(uint8_t* bytes, size_t byteLength)
    - [[nodiscard]] kraken::binding::qjs::ExecutionContext* getContext() const
    - void invokeModuleEvent(NativeString* moduleName, const char* eventType, void* event, NativeString* extra)
    - void reportError(const char* errmsg)
  - Context/state:
    - int32_t contextId
  - Test-only members (conditional IS_TEST):
    - void* owner
    - JSBridgeDisposeCallback disposeCallback{nullptr}
  - Public data/comments:
    - One-thread-at-a-time access: not safe for multi-threads; designed for multiple KrakenPages on one thread
    - Context access uses m_context; raw pointer usage discouraged but used for disposal access
  - Private members:
    - binding::qjs::ExecutionContext* m_context
    - JSExceptionHandler m_handler

- Notes:
  - Raw pointer usage for m_context due to disposal needs
  - Provides bridge between Kraken and QuickJS for per-widget JS object management

- End: closes kraken namespace and include guard.

Failing step (docker build phase)
- [builder 8/8] RUN cmake --build bridge/build --config Release

Exact error message and exit code
- The build ends with exit code 2:
  ERROR: failed to build: failed to solve: process "/bin/sh -c cmake --build bridge/build --config Release" did not complete successfully: exit code: 2
- Primary compilation errors (from /work/bridge/kraken_bridge.cc), e.g.:
  /work/bridge/kraken_bridge.cc: In function 'int32_t {anonymous}::searchForAvailableContextId()':
  /work/bridge/kraken_bridge.cc:83:17: error: 'kraken::KrakenPage' has not been declared
- A cascade of similar errors follows, all stating that 'kraken::KrakenPage' has not been declared / not named as a type, across multiple lines in kraken_bridge.cc.

Version/mismatch information
- C/C++ compiler reported by CMake: GNU 12.2.0 (The C compiler identification is GNU 12.2.0; The CXX compiler identification is GNU 12.2.0)

Missing packages or files mentioned
- No explicit missing file/package errors such as "file not found" or "missing package" were reported. The failures are due to compile-time type declarations: the code references kraken::KrakenPage but the type is not declared/visible in kraken_bridge.cc.

Notes
- The log shows prior steps completed (Dockerfile steps, cmake configuration, npm install), but the final step fails due to the KrakenPage declaration issue rather than missing dependencies.

Exact error message and exit code
- exit code: 1
- fatal: not a git repository (or any of the parent directories): .git
- CMake Error at CMakeLists.txt:359 (string):
  string sub-command REPLACE requires at least four arguments.
- 
- -- Configuring incomplete, errors occurred!
- See also "/work/bridge/build/CMakeFiles/CMakeOutput.log".

Failing command/step
- Failing command: cmake -S bridge -B bridge/build -DCMAKE_BUILD_TYPE=Release

    - (and numerous similar errors about 'kraken::KrakenPage' not declared / not a type across many lines)
  - Result: gmake exited with errors while building kraken_bridge.cc.o; the overall CMake build/install failed with exit code 2.

- Failing command/step (full command):
  - mkdir -p bridge/build     && cmake -S bridge -B bridge/build -DCMAKE_BUILD_TYPE=Release     && cmake --build bridge/build --config Release     && cmake --install bridge/build --prefix /usr/local

- Missing packages or files mentioned:
  - None explicitly reported as missing; the failure is a compile-time error in kraken_bridge.cc due to KrakenPage being undeclared.

- Version information (from the log):
  - C compiler identification: GNU 12.2.0
  - CXX compiler identification: GNU 12.2.0

- Notable warning:
  - 1 warning found: UndefinedVar: Usage of undefined variable '$LD_LIBRARY_PATH' (line 30)

- Summary of cause and next steps:
  - Cause: kraken_bridge.cc references kraken::KrakenPage, but KrakenPage is not declared in the visible scope (likely a missing header include, incorrect namespace, or a change in KrakenPage definition).
  - Next steps:
    - Verify the header declaring kraken::KrakenPage is included in kraken_bridge.cc and in the correct order.
    - Check for recent changes to KrakenPage’s namespace or class name; adjust include paths or namespace usage.
    - If KrakenPage was renamed or moved, update references or add the proper forward declaration/header.
    - Re-run build after ensuring KrakenPage is properly declared and visible to the kraken_bridge.cc compilation unit.

Summary of actionable items and key details from the tool output

- Build-time engine options (platform bindings):
  - KRAKEN_JSC_ENGINE or KRAKEN_QUICK_JS_ENGINE (include paths differ accordingly).
  - Files: kraken_bridge.h, dart_methods.h; bindings/jsc/KOM/performance.h or quickjs/quickjs.h and bridge/page.h; optional bridge_jsc.h.

- Platform/system detection:
  - SYSTEM_NAME defined as: windows, android, linux, ios, macos, or unknown (based on compile-time macros).

- Global/runtime state:
  - inited (atomic bool), poolIndex (atomic int32), maxPoolSize (int), screen (NativeScreen), uiThreadId (std::thread::id).
  - getUIThreadId() returns UI thread id.

- Error handling:
  - printError(contextId, errmsg) dispatches to Dart onJsError/onJsLog (if provided) and logs with KRAKEN_LOG(ERROR).

- Page/context pool management:
  - disposeAllPages(): disposes all pages up to poolIndex and resets pool.
  - searchForAvailableContextId(): finds first nullptr slot in pageContextPool.
  - initJSPagePool(poolSize): initializes UI thread, disposes old bridge if reinitialized, allocates pageContextPool array, creates page 0 with printError, sets inited and maxPoolSize.
  - disposePage(contextId): deletes page and clears pool entry.
  - allocateNewPage(targetContextId): allocates new page; handles -1 auto-assign, bounds, and existence assertion.
  - getPage(contextId): returns page if valid; otherwise nullptr.
  - checkPage(contextId): validates page existence; overload checks page vs provided context.

- Script evaluation & HTML parsing:
  - evaluateScripts(contextId, code, bundleFilename, startLine)
  - evaluateQuickjsByteCode(contextId, bytes, byteLen)
  - parseHTML(contextId, code, length)
  - reloadJsContext(contextId): replaces page with a new KrakenPage instance.

- Events & module interactions:
  - invokeModuleEvent(contextId, moduleName, eventType, event, extra)
  - registerDartMethods(methodBytes, length)
  - registerPluginByteCode(bytes, length, pluginName)

- Screen & info:
  - createScreen(width, height): stores dimensions in global screen.
  - KrakenInfo getKrakenInfo(): lazily creates KrakenInfo with app_name "Kraken", app_revision (APP_REV), app_version (APP_VERSION), system_name (SYSTEM_NAME).

- Console/UI handling:
  - setConsoleMessageHandler(handler)
  - dispatchUITask(contextId, context, callback): ensures called on UI thread.
  - flushUITask(contextId)
  - registerUITask(contextId, task, data)
  - flushUICommandCallback()
  - getUICommandItems(contextId), getUICommandItemSize(contextId), clearUICommandItems(contextId)

- Context lifecycle hooks:
  - registerContextDisposedCallbacks(contextId, task, data): currently asserts validity and fetches context (implementation placeholder).

- Profiling:
  - profileModeEnabled(): returns 1 if ENABLE_PROFILE defined, else 0.

- Native string management:
  - NativeString::clone(): deep-clones string data.
  - NativeString::free(): frees string memory.

Notes:
- APP_REV and APP_VERSION are macros; SYSTEM_NAME is derived from platform macros.
- The code maintains a per-context pool of KrakenPage instances for multiple contexts.

Failing step (Docker build, builder 7/7):
- RUN mkdir -p bridge/build     && cmake -S bridge -B bridge/build -DCMAKE_BUILD_TYPE=Release -DKRAKEN_JS_ENGINE=quickjs     && cmake --build bridge/build --config Release     && cmake --install bridge/build --prefix /usr/local

Exact error messages and exit code:
- fatal: not a git repository (or any of the parent directories): .git
- CMake Error at CMakeLists.txt:359 (string):
-   string sub-command REPLACE requires at least four arguments.
- 
- Configuring incomplete, errors occurred!
- Exit code: 1

Missing packages/files mentioned:
- Not a missing package, but a Git repo issue: fatal: not a git repository (the code generator expects a .git context). This implies the build attempted to access a Git repo that isn’t present in the build context.

Warnings noted (not repeated):
- UndefinedVar: Usage of undefined variable '$LD_LIBRARY_PATH' (line 30)

Version/tooling context:
- The C/C++ toolchain at the point of failure shows: The C compiler identification is GNU 11.4.0 and The CXX compiler identification is GNU 11.4.0 (indicating GCC 11.x in use).
- Earlier steps show heavy GCC/Lib upgrades (gcc-12-base, libstdc++6, etc.) during a prior apt-get install, suggesting a mixed GCC version environment in the image.

No files found matching pattern.

- Project/class: KrakenPage (namespace kraken) - C++ implementation for page lifecycle in Kraken JS engine.

- Key files/paths referenced:
  - polyfill.h
  - bindings/qjs/… (console, bom, dom, events, style, etc.)
  - page.h, dart_methods.h, module_manager.h
  - Includes for various element bindings: anchor_element, canvas_element, input_element, object_element, script_element, textarea_element, image_element, template_element
  - node/document/element bindings and event types (close/gesture/input/intersection/media/mouse/popstate/touch)

- Core data and state:
  - static: std::unordered_map<std::string, NativeByteCode> KrakenPage::pluginByteCode
  - static: ConsoleMessageHandler KrakenPage::consoleMessageHandler
  - static: KrakenPage** KrakenPage::pageContextPool
  - NativeByteCode stored per plugin and executed via evaluateByteCode

- KrakenPage constructor (int32_t contextId, handler):
  - Creates ExecutionContext(contextId, handler, this)
  - Optional profiling points (ENABLE_PROFILE): marks for JS context init, native method init, polyfill init
  - Binds a suite of JS bindings into the context (console, timer, screen, moduleManager, eventTarget, blob, window, event, customEvent, node, documentFragment, textNode, commentNode, element, various element bindings, document, performance)
  - Initializes Kraken polyfill via initKrakenPolyFill(this)
  - Executes any plugin bytecode present in pluginByteCode
  - Optional profiling end marks for polyfill init

- parseHTML(const char* code, size_t length):
  - If context invalid, returns false
  - Gets documentElement, then iterates its childNodes and removes ELEMENT_NODE children (removes body/head content as part of “Remove all Nodes including body and head”)
  - Frees documentElement.jsObject
  - Calls HTMLParser::parseHTML(code, length, documentElement)
  - Returns true

- invokeModuleEvent(NativeString* moduleName, const char* eventType, void* rawEvent, NativeString* extra):
  - If context invalid, return
  - If rawEvent present, builds EventInstance via Event::buildEventInstance and uses its jsObject
  - Creates moduleNameValue (JS string); parses extra JSON if provided
  - Iterates module_job_list (ModuleContext entries), calling each module callback with three args: moduleNameValue, eventObject, extraObject
  - Handles/cleans up return values and freed JS values
  - Frees moduleNameValue, eventObject, extraObject as applicable

- evaluateScript overloads:
  - evaluateScript(const NativeString* script, const char* url, int startLine)
    - If ENABLE_PROFILE: prefixes with a patch to mark js_parse_time_end and measures parse time
    - Evaluates via m_context->evaluateJavaScript
  - evaluateScript(const uint16_t* script, size_t length, const char* url, int startLine)
  - evaluateScript(const char* script, size_t length, const char* url, int startLine)

- Bytecode/execution helpers:
  - dumpByteCode(const char* script, size_t length, const char* url, size_t* byteLength)
  - evaluateByteCode(uint8_t* bytes, size_t byteLength)
  - Both check context validity

- Destructor ~KrakenPage():
  - If IS_TEST and disposeCallback set, calls disposeCallback(this)
  - Deletes m_context
  - Clears pageContextPool[contextId] = nullptr

- Other utilities:
  - reportError(const char* errmsg) -> forwards to m_handler
  - Context validity checked via m_context->isValid() in relevant methods

- Profiling/build notes:
  - ENABLE_PROFILE guards emit performance marks for JS context init, native method init, polyfill init, and JS parse time

- Actionable hooks:
  - pluginByteCode can inject additional bytecode to be evaluated at construction
  - disposeCallback support under test builds
  - module_job_list allows multiple module callbacks to respond to module events

- No explicit error messages present in the excerpt. Copyright/version note: 2021-present The Kraken authors.

Summary:

- File: kraken/js/qjs_bridge.h (header guard KRAKEN_JS_QJS_BRIDGE_H_). Part of Kraken project.

- Includes:
  - <quickjs/quickjs.h>
  - bindings/qjs/executing_context.h
  - bindings/qjs/html_parser.h
  - include/kraken_bridge.h

- Namespace: kraken

- Type alias:
  - using JSBridgeDisposeCallback = void (*)(KrakenPage* bridge);

- KrakenPage class:
  - Purpose: Manages all JS objects created by a Kraken Flutter widget. Each Kraken widget has a corresponding KrakenPage; objects are not shared across pages. Safe to allocate many KrakenPages on one thread, but not thread-safe across threads.

  - Static members:
    - KrakenPage** pageContextPool
    - ConsoleMessageHandler consoleMessageHandler
    - std::unordered_map<std::string, NativeByteCode> pluginByteCode (static, stores bytecodes registered by Kraken plugins)

  - Constructors/Destructor:
    - KrakenPage() = delete
    - KrakenPage(int32_t jsContext, const JSExceptionHandler& handler)
    - ~KrakenPage()

  - Public methods:
    - void evaluateScript(const NativeString* script, const char* url, int startLine)
    - void evaluateScript(const uint16_t* script, size_t length, const char* url, int startLine)
    - void evaluateScript(const char* script, size_t length, const char* url, int startLine)
    - bool parseHTML(const char* code, size_t length)
    - uint8_t* dumpByteCode(const char* script, size_t length, const char* url, size_t* byteLength)
    - void evaluateByteCode(uint8_t* bytes, size_t byteLength)
    - [[nodiscard]] kraken::binding::qjs::ExecutionContext* getContext() const
    - void invokeModuleEvent(NativeString* moduleName, const char* eventType, void* event, NativeString* extra)
    - void reportError(const char* errmsg)
  - Data members:
    - int32_t contextId
    - #if IS_TEST
      - void* owner
      - JSBridgeDisposeCallback disposeCallback{nullptr}
      #endif

  - Public context accessor:
    - [[nodiscard]] kraken::binding::qjs::ExecutionContext* getContext() const { return m_context; }

  - Private members:
    - binding::qjs::ExecutionContext* m_context
    - JSExceptionHandler m_handler

  - Notes:
    - Comments indicate raw pointer usage for m_context due to dispose-time access, acknowledging fragility and intent to refactor.

- Additional notes:
  - The class includes a note on thread-safety and the need for single-threaded access to KrakenPage instances.

Summary of Docker build error

- Failing step (command):
  [builder 9/10] RUN cmake -S bridge -B bridge/build -DCMAKE_BUILD_TYPE=Release
- Exit code: 1

- Exact error message and context to preserve:
  Configuring incomplete, errors occurred!
  See also "/workspace/bridge/build/CMakeFiles/CMakeOutput.log".
  fatal: not a git repository (or any of the parent directories): .git
  CMake Error at CMakeLists.txt:359 (string):
    string sub-command REPLACE requires at least four arguments.

- Missing packages or files mentioned:
  - Not a Debian package issue; the log indicates a missing Git repository metadata:
    fatal: not a git repository (or any of the parent directories): .git
  - Implied missing .git directory/metadata rather than a package/file download failure.

- Version mismatch / environment details noted:
  - C/C++ compilers detected: GNU 12.2.0 (shown in the log during cmake configuration).
  - The failure appears due to CMake configuration logic (string(REPLACE …)) rather than a straightforward version mismatch, though the .git absence may contribute to the configuration error.

Failing step - [builder 11/11] RUN cmake --build bridge/build --config Release
- Exit: The process exited with code 2 (build failure). Final Docker error: Dockerfile:30 ... ERROR: failed to build: failed to solve: process "/bin/sh -c cmake --build bridge/build --config Release" did not complete successfully: exit code: 2
- Exact error messages (root cause)
  - The first clustered compiler errors originate in kraken_bridge.cc

  - ...and many additional errors referencing 'kraken::KrakenPage' not being declared or named as a type
- Build/logging notes
  - The linker/build step then fails with:
    - gmake[2]: *** [CMakeFiles/kraken.dir/build.make:76: CMakeFiles/kraken.dir/kraken_bridge.cc.o] Error 1
    - gmake[1]: *** [CMakeFiles/Makefile2:87: CMakeFiles/kraken.dir/all] Error 2
    - gmake: *** [Makefile:91: all] Error 2
- Context / likely cause
  - KrakenPage type is not declared/visible where kraken_bridge.cc uses it. Indicates missing/incorrect header inclusion or a header/dependency order issue in Kraken bridge code, not an explicit Dockerfile package missing.
- Version / compatibility notes observed
  - C compiler: GNU 12.2.0
  - C++ compiler: GNU 12.2.0
  - npm notices earlier (unrelated to this failure): New minor version of npm available: 11.9.0 -> 11.11.1
- Missing packages or files mentioned
  - Not explicitly missing; issue is a type/definition missing in code (KrakenPage) during compilation.
- Version mismatch info
  - No explicit version mismatch reported beyond standard GNU 12.2.0 and npm update note.

Summary (under 1500 chars):

- Platform detection defines SYSTEM_NAME per build target: "windows" (Win/Win64/Cygwin), "android", "linux", "ios", "macos", or "unknown".
- Global state:
  - inited (atomic bool), poolIndex (atomic int), maxPoolSize (int)
  - NativeScreen screen, uiThreadId, plus getUIThreadId()
- Error handling:
  - printError(contextId, errmsg): calls Dart onJsError/onJsLog (if set) and KRAKEN_LOG(ERROR)
- Page pool management (KrakenPage context pool):
  - disposeAllPages(): disposes pages up to poolIndex, resets poolIndex and inited
  - searchForAvailableContextId(): returns first nullptr slot or -1
  - initJSPagePool(int poolSize): initializes pool array, assigns page 0 with KrakenPage(0, printError), stores uiThreadId, sets maxPoolSize
  - disposePage(contextId): deletes page and clears pool slot
  - allocateNewPage(targetContextId): allocates/returns a new KrakenPage at the given/next slot; asserts no existing page
  - getPage(contextId): returns page pointer or nullptr
  - checkPage(contextId): validates page is initialized
  - checkPage(contextId, context): validates page context matches
- Page operations (bridge to JS context):
  - evaluateScripts, evaluateQuickjsByteCode, parseHTML
  - reloadJsContext: replaces page with new KrakenPage instance
  - invokeModuleEvent
- Dart method and screen helpers:
  - registerDartMethods(...)
  - createScreen(width, height): updates and returns screen
  - getKrakenInfo(): lazily creates KrakenInfo with app_name "Kraken", app_revision APP_REV, app_version APP_VERSION, system_name (SYSTEM_NAME)
  - setConsoleMessageHandler(...)
- UI and task handling:
  - dispatchUITask(contextId, context, callback)
  - flushUITask(contextId)
  - registerUITask(contextId, Task, data)
  - flushUICommandCallback
  - getUICommandItems(contextId), getUICommandItemSize(contextId), clearUICommandItems(contextId)
  - registerContextDisposedCallbacks(contextId, Task, data) (no-op body in snippet)
- Plugins and profiling:
  - registerPluginByteCode(bytes, length, pluginName): stores in KrakenPage::pluginByteCode
  - profileModeEnabled(): 1 if ENABLE_PROFILE, else 0
- Native utilities:
  - NativeString::clone(): deep copy
  - NativeString::free(): delete[]
- Engine guards:
  - Code path switches on KRAKEN_JSC_ENGINE or KRAKEN_QUICK_JS_ENGINE
- Key files/headers referenced:
  - kraken_bridge.h, dart_methods.h, foundation/inspector_task_queue.h, foundation/logging.h, foundation/ui_task_queue.h, bridge_jsc.h, KOM/performance.h, quickjs/quickjs.h, bridge/page.h
- Notable constants/macros referenced but defined elsewhere: APP_REV, APP_VERSION, APP_REVISION, APP_VERSION, ENABLE_PROFILE

Actionable items preserved:
- Core function names and their purposes (init/dispose/allocate/get/check pages, evaluate scripts, reload context, event invocation, plugin bytecode registration, UI task/command access, KrakenInfo population).

- Engine wiring:
  - If KRAKEN_JSC_ENGINE: include kraken_bridge_jsc.h
  - ElseIf KRAKEN_QUICK_JS_ENGINE: (no additional include)

Failing step
- Step: builder 12/13
- Command: RUN cmake -S bridge -B bridge/build -DCMAKE_BUILD_TYPE=Release -DKRAKEN_JS_ENGINE=quickjs
- Exit code: 1
- Exact error messages (preserved):
  ERROR: process "/bin/sh -c cmake -S bridge -B bridge/build -DCMAKE_BUILD_TYPE=Release -DKRAKEN_JS_ENGINE=quickjs" did not complete successfully: exit code: 1

  7.134 -- Configuring incomplete, errors occurred!
  See also "/workspace/bridge/build/CMakeFiles/CMakeOutput.log".
  fatal: not a git repository (or any of the parent directories): .git
  CMake Error at CMakeLists.txt:359 (string):
    string sub-command REPLACE requires at least four arguments.

Missing packages/files mentioned
- Not explicitly missing packages. The log indicates a Git repository issue:
  - fatal: not a git repository (or any of the parent directories): .git
  This implies the build expected a .git directory/repo present in the working tree, which is not available.

Version/compatibility notes
- Observed compilers during CMake configuration:
  - The C compiler identification is GNU 12.2.0
  - The CXX compiler identification is GNU 12.2.0
- Build option in use: -DKRAKEN_JS_ENGINE=quickjs

Context
- This failure occurs during the CMake configure step for the bridge component, prior to building bridge/build with Release configuration, and is halted by a CMake syntax error (string REPLACE) likely triggered by missing Git metadata or misconfigured CMakeLists.txt.

bridge/page.h

- Location: Kraken project header KRAKEN_JS_QJS_BRIDGE_H_, within namespace kraken.

- Purpose: KrakenPage class manages all JavaScript objects created by the Kraken Flutter widget. Each Kraken widget has a corresponding KrakenPage; objects are not shared across pages. Page lifecycle and context are isolated per page.

- Threading: Safe to allocate many KrakenPages on one thread, but not safe for multi-threaded access to a single page.

- Static/state:
  - pageContextPool: KrakenPage**
  - consoleMessageHandler: ConsoleMessageHandler
  - pluginByteCode: std::unordered_map<std::string, NativeByteCode> (bytecodes registered by Kraken plugins)

- Construction/destruction:
  - KrakenPage(int32_t jsContext, const JSExceptionHandler& handler)
  - ~KrakenPage()

- API surface:
  - evaluateScript overloads:
    - void evaluateScript(const NativeString* script, const char* url, int startLine)
    - void evaluateScript(const uint16_t* script, size_t length, const char* url, int startLine)
    - void evaluateScript(const char* script, size_t length, const char* url, int startLine)
  - parseHTML(const char* code, size_t length)
  - uint8_t* dumpByteCode(const char* script, size_t length, const char* url, size_t* byteLength)
  - void evaluateByteCode(uint8_t* bytes, size_t byteLength)
  - [[nodiscard]] kraken::binding::qjs::ExecutionContext* getContext() const
  - void invokeModuleEvent(NativeString* moduleName, const char* eventType, void* event, NativeString* extra)
  - void reportError(const char* errmsg)
  - int32_t contextId

- Testing support (compiled with IS_TEST):
  - void* owner
  - JSBridgeDisposeCallback disposeCallback{nullptr}

- Internal/private:
  - m_context: binding::qjs::ExecutionContext*
  - m_handler: JSExceptionHandler
  - Notes about using raw pointers for context access during disposal; raw pointers are fragile and may require refactoring

- Includes/dependencies:
  - <quickjs/quickjs.h>, "bindings/qjs/executing_context.h", "bindings/qjs/html_parser.h", "include/kraken_bridge.h"
  - Standard containers: <atomic>, <deque>, <vector>

- Misc:
  - Class is KrakenPage final; provides per-page JS execution and event handling within the Kraken wrapper.

Actionable summary of the error

- Exact error message and exit code:
  - fatal error: bridge/page.h: No such file or directory
  - Exit code: 2
- Failing command/step:
  - [builder 12/12] RUN cmake --build bridge/build --config Release
  - Dockerfile:33 (the line executing the failing build)
- Missing packages or files mentioned:
  - Missing file: bridge/page.h (No such file or directory)
- Version/mismatch notes:
  - Compiler: GNU 12.2.0 (C and C++ detected as GNU 12.2.0)
  - No explicit version mismatch reported; the failure is due to a missing header, not a toolchain mismatch.

Context: The build progressed through prior steps (CMake configure, etc.) but fails during the final build with a missing header, likely due to a missing header file or an include-path misconfiguration. Next steps would be to verify that bridge/page.h exists in the source tree and that the include path for bridge headers is correct in the CMake setup.

- Additional context:
  - This header defines the page-level bridge between Kraken Flutter widgets and the QuickJS runtime, managing JavaScript objects per KrakenPage, and providing evaluation, HTML parsing, bytecode handling, and module event reporting.

Summary of Docker build error

- Exact error message and exit code
  - fatal error: polyfill.h: No such file or directory
  - Exit code: 2

- Failing command/step
  - The Docker build step:
    RUN cmake -S bridge -B bridge/build -DCMAKE_BUILD_TYPE=Release -DKRAKEN_JS_ENGINE=quickjs -DCMAKE_CXX_FLAGS="-I/workspace"   && cmake --build bridge/build --config Release
  - (builder 12/12)

- Missing packages or files mentioned
  - Missing header file: polyfill.h (No such file or directory) referenced in /workspace/bridge/page.cc:5:10

- Version/mismatch information
  - C compiler: GNU 12.2.0
  - C++ compiler: GNU 12.2.0
  - Note: CMake emitted a warning about an unused variable: KRAKEN_JS_ENGINE, but this is not a hard mismatch.

- File/context: KrakenPage implementation in namespace kraken. Includes headers from bindings/qjs, polyfill, page.h, and dart_methods-related code. Uses QJS bindings and a large set of DOM/event bindings.

- Core data structures (static/state):
  - pluginByteCode: unordered_map<string, NativeByteCode>
  - consoleMessageHandler: ConsoleMessageHandler
  - KrakenPage** pageContextPool
  - Console bindings, module manager, event targets, DOM bindings, and polyfill init are wired in the constructor.

- KrakenPage(int32_t contextId, const JSExceptionHandler& handler) constructor:
  - Creates ExecutionContext with given contextId and handler.
  - Optional profiling marks (PERF_JS_CONTEXT_INIT_START/END, PERF_JS_NATIVE_METHOD_INIT_START) if ENABLE_PROFILE.
  - Binds a large set of features to the JS context (console, timer, screen, module manager, event targets, blob, window, event, customEvent, DOM nodes and elements, various specific element bindings, events, document, performance).
  - Initializes Kraken polyfill (initKrakenPolyFill).
  - Evaluates plugin byte codes from pluginByteCode.
  - Optional profiling marks around polyfill init (PERF_JS_POLYFILL_INIT_START/END).

- public methods:
  - parseHTML(const char* code, size_t length): Validates context; clears all child nodes of the document element (removing ELEMENT_NODEs) and frees associated JS objects, then parses HTML via HTMLParser::parseHTML(code, length, documentElement). Returns true on success.
  - invokeModuleEvent(NativeString* moduleName, const char* eventType, void* rawEvent, NativeString* extra): If context invalid, return. Builds an EventInstance for rawEvent (if provided), creates moduleNameValue string, parses extra JSON (if provided), then iterates module_job_list to call each module callback with [moduleNameValue, eventObject, extraObject], handling exceptions and freeing values. Frees moduleNameValue and optionally eventObject/extraObject.
  - evaluateScript overloads:
    - evaluateScript(const NativeString* script, const char* url, int startLine): If profiling enabled, prepends a parse-time performance mark to the code before evaluation; otherwise evaluates directly.
    - evaluateScript(const uint16_t* script, size_t length, const char* url, int startLine): direct evaluation.
    - evaluateScript(const char* script, size_t length, const char* url, int startLine): direct evaluation.
  - dumpByteCode(const char* script, size_t length, const char* url, size_t* byteLength): If context valid, delegates to m_context->dumpByteCode.
  - evaluateByteCode(uint8_t* bytes, size_t byteLength): If context valid, delegates to m_context->evaluateByteCode.
  - ~KrakenPage(): If IS_TEST, calls disposeCallback(this). Deletes m_context and clears pageContextPool[contextId].
  - reportError(const char* errmsg): Calls m_handler with contextId and errmsg.

- Notable behaviors:
  - Context validity checks guard all public actions.
  - Profiling gates (ENABLE_PROFILE) wrap key phases: context init, native method init, polyfill init, and JS parse timing.
  - Module event delivery uses a linked list (m_context->module_job_list) of ModuleContext entries with callbacks, passing module name, event, and optional extra data as JSON.
  - HTML parsing clears all existing nodes in the document element before parsing.
  - Bytecode and script evaluation are flexible via multiple overloads.
  - Console/JS binding setup and polyfill initialization happen at construction.

- Actionable references (paths/ids seen in code):
  - Includes: bindings/qjs/qjs_patch.h, polyfill.h, page.h, and numerous bindings/qjs/dom/*, bindings/qjs/bom/*, module_manager.h, etc.
  - Profiling IDs: PERF_JS_CONTEXT_INIT_START/END, PERF_JS_NATIVE_METHOD_INIT_START/END, PERF_JS_POLYFILL_INIT_START/END, PERF_JS_PARSE_TIME_START, PERF_JS_PARSE_TIME_END.
  - Keys: pluginByteCode, consoleMessageHandler, KrakenPage::pageContextPool, execute/evaluate methods, invokeModuleEvent, parseHTML, reportError.

If you want a shorter gist: This file implements KrakenPage, initializes a JS execution context with extensive bindings, loads and runs plugin bytecodes, supports HTML parsing, module-event dispatch, and script/bytecode evaluation with optional profiling and test hooks.
