This allows multiple threads to execute JavaScript in parallel + by giving each thread its own Context. The `JERRY_EXTERNAL_CONTEXT` build + flag enables this multi-context support. + + ### Scope and Value Lifetime + JerryScript uses heap-based reference counting (not a stack like Lua/Duktape). + To provide deterministic cleanup similar to stack-based engines: + + - **Scope** tracks values created within it and releases one reference to + each when the scope ends. Values that were copied elsewhere survive; + values that remained local are freed. + - **Value** holds its own reference via jerry_value_copy/jerry_value_free. + Values can safely outlive their creating Scope if copied. + + ### Integer Limitations + JerryScript only guarantees 32-bit integer precision. Values outside the + int32 range (approximately +/-2 billion) are converted to strings when passed + to JavaScript to avoid wraparound bugs. When reading values back, integers + that fit in int64 are returned as integers; others remain as doubles. + + ### DOM to JS Conversion Strategy + - **Objects**: Use lazy Proxy wrappers to avoid infinite recursion from + circular references (e.g., Handlebars symbol contexts that reference + parent symbols). Properties are converted on-demand when accessed. + - **Arrays**: Converted eagerly (snapshot semantics) because they rarely + contain circular references. This means JS mutations don't affect the + original C++ array and vice versa. + - **Functions**: Wrapped bidirectionally so JS can call C++ functions and + C++ can invoke JS functions through dom::Function. + + ### Thread Safety + Each Context has its own mutex serializing operations on that context. + Different Contexts can execute in parallel on different threads. Values + hold a shared_ptr to their Context, keeping it alive and using the mutex + for all JerryScript operations. + + ### Port Functions + JerryScript requires "port functions" for platform-specific operations. + We use the default jerry-port library (JERRY_PORT=ON) for most functions + (logging, time, fatal errors, etc.), but provide custom implementations + of the context management functions: + - `jerry_port_context_alloc`: Allocates context + heap memory + - `jerry_port_context_free`: Frees context memory + - `jerry_port_context_get`: Returns current thread's active context + + The default jerry-port context functions use a static global pointer, + limiting all threads to a single shared context. When building with + JERRY_EXTERNAL_CONTEXT=ON, these functions are excluded from jerry-port + (see third-party/patches/jerryscript/CMakeLists.txt), and mrdocs provides + TLS-based implementations that allow each thread to have its own active + context, enabling parallel JavaScript execution. */ namespace js { -/** Opaque tag that allows bridge classes to reach JS internals. -*/ -/** Grants friend-level access to internal scopes. -*/ -struct Access; class Context; class Scope; @@ -70,9 +127,9 @@ enum class Type number, /// The value is a string string, - /// The value is a function + /// The value is an object object, - /// The value is an array + /// The value is a function function, /// The value is an array array @@ -80,159 +137,106 @@ enum class Type //------------------------------------------------ -/** Represents either a property name or array index when addressing JS objects. -*/ -class Prop -{ - unsigned int index_; - std::string_view name_; +/** An isolated JavaScript interpreter instance. -public: - /** Create a property by name. - */ - constexpr Prop(std::string_view name) noexcept - : index_(0) - , name_(name) - { - } + Each Context owns an independent JerryScript interpreter with its own + 512KB heap.

The design supports M:N +// threading: any number of Context objects (interpreters) can be used by +// any number of threads, with proper synchronization. +// +// Key Components: +// +// - Context: Owns an isolated JerryScript interpreter with its own 512KB +// heap. Multiple Contexts can exist simultaneously—the count is not +// limited by thread count. Each Context has a mutex for thread-safe +// access; a thread activates a Context before performing operations, +// then releases it for other threads to use. +// +// - Scope: Provides RAII-style value tracking within a Context. When a +// Scope is destroyed, it releases references to values created within +// it. Values that were copied elsewhere (returned, stored) survive; +// values that remained local are freed. This provides deterministic +// cleanup similar to stack-based scripting engines. +// +// - Value: Handle to a JavaScript value. Internally stores a jerry_value_t +// (as uint32_t) plus a shared_ptr to the owning Context. Before any +// JerryScript operation, the Value locks and activates its Context, +// ensuring thread safety and correct TLS state. +// +// Threading Model: +// +// JerryScript is single-threaded per context, but we can have multiple +// contexts. Thread-local storage (TLS) tracks which context is currently +// active on each thread. When a thread needs to use a Context: +// +// 1. Lock the Context's mutex (serializes access to that interpreter) +// 2. Set TLS to point to that Context's interpreter +// 3. Perform JerryScript operations +// 4. Release the lock (TLS may still point there; that's fine) +// +// This allows patterns like: +// - 4 threads sharing 4 Contexts (1:1, maximum parallelism) +// - 4 threads sharing 100 Contexts (threads switch between contexts) +// - 1 thread using multiple Contexts sequentially +// +// DOM Conversion: +// +// - DOM → JS (toJsValue): Objects use lazy Proxy wrappers to avoid +// infinite recursion from circular references (e.g., Handlebars symbol +// contexts).
