v1.8.0

Added

• ASGI NIF Optimizations - Six optimizations for high-performance ASGI request handling

  • Direct Response Tuple Extraction - Extract (status, headers, body) directly without generic conversion
  • Pre-Interned Header Names - 16 common HTTP headers cached as PyBytes objects
  • Cached Status Code Integers - 14 common HTTP status codes cached as PyLong objects
  • Zero-Copy Request Body - Large bodies (≥1KB) use buffer protocol for zero-copy access
  • Scope Template Caching - Thread-local cache of 64 scope templates keyed by path hash
  • Lazy Header Conversion - Headers converted on-demand for requests with ≥4 headers

• erlang_asyncio Module - Asyncio-compatible primitives using Erlang's native scheduler

  • erlang_asyncio.sleep(delay, result=None) - Sleep using Erlang's erlang:send_after/3
  • erlang_asyncio.run(coro) - Run coroutine with ErlangEventLoop
  • erlang_asyncio.gather(*coros) - Run coroutines concurrently
  • erlang_asyncio.wait_for(coro, timeout) - Wait with timeout
  • erlang_asyncio.wait(fs, timeout, return_when) - Wait for multiple futures
  • erlang_asyncio.create_task(coro) - Create background task
  • Event loop functions: get_event_loop(), new_event_loop(), set_event_loop(), get_running_loop()

• Erlang Sleep NIF - Synchronous sleep primitive for Python

  • py_event_loop._erlang_sleep(delay_ms) - Sleep using Erlang timer
  • Releases GIL during sleep, no Python event loop overhead

• Scalable I/O Model - Worker-per-context architecture

  • py_event_worker - Dedicated worker process per Python context
  • Combined FD event dispatch and reselect via handle_fd_event_and_reselect NIF

• New Test Suite - test/py_erlang_sleep_SUITE.erl with 8 tests

Performance

• ASGI marshalling optimizations - 40-60% improvement for typical ASGI workloads
• Eliminates event loop overhead for sleep operations (~0.5-1ms saved per call)
• Sub-millisecond timer precision via BEAM scheduler (vs 10ms asyncio polling)
• Zero CPU when idle - event-driven, no polling
