- Add OpenAPI 3.0 specification builder with fluent API
- Add Swagger UI integration for interactive API documentation
- Add comprehensive OpenAPI data structures (schemas, parameters, responses, etc.)
- Add swagger_demo.v example with Pet Store API demonstration
- Use global variables for shared mutable state in demo handlers
- Add property-based tests for OpenAPI serialization and validation
- Update README with Swagger UI documentation
- Add HTTP version detection in parse_http_request_usockets
- Return Connection: close header for HTTP/1.0 requests
- Call shutdown() for graceful connection close after HTTP/1.0 response
- Fix missing is_http11 parameter in WebSocket upgrade handler
- Support HTTP/1.0 with Connection: Keep-Alive header (ab -k mode)
- Optimize: only check Connection header value for keep-alive (like Go net/http)
Root cause: ab uses HTTP/1.0 by default, but server always returned
Connection: keep-alive, causing ab to wait for server to close connection.

- Clarify that Windows requires gcc (tcc does not support .a static library format)
- Add separate build commands for macOS/Linux and Windows
- Document pre-compiled library locations by platform
- Add w64devkit as recommended MinGW download option
- Organize lib directory by platform: windows/, macos-arm64/, macos-x64/, linux/
- Update build.sh to support unified build process for Windows/macOS/Linux
- Compile libuv + uSockets and merge into complete static library
- Update usockets.v conditional compilation to point to new directory structure
- Optimize benchmark tests with connection pooling for high concurrency testing
- Clean up unused legacy library files
Performance test results (Windows):
- 1000 concurrent, 1M requests: 35,223 req/s
- 10000 concurrent, 1M requests: 26,884 req/s
Previously, PicoevStreamWriter used picohttpparser.Response.raw() to write
streaming data, which only buffered the data until the entire request handler
completed. This caused SSE responses to be delayed until all sleep() calls
finished (e.g., 2.89s delay for /stream-text endpoint).
Changes:
- Modified PicoevStreamWriter to use socket fd directly from picohttpparser.Response
- Implemented write_to_fd() using C.send() for immediate data delivery
- Updated handle_picoev_streaming_response() to write HTTP headers directly to socket
- Added C.send() function declaration for direct socket writes
This fix enables true real-time streaming where each write() or write_sse()
call immediately sends data to the client, rather than buffering until
the callback completes.
All 74 test files pass with no regressions.
Add Server-Sent Events (SSE) and streaming response support with three
streaming functions:
- stream(): Basic binary streaming with chunked transfer encoding
- stream_text(): Text streaming with proper Content-Type headers
- stream_sse(): SSE event streaming with full event field support
Features:
- SSEEvent struct with data, event, id, retry fields
- StreamContext for write, writeln, write_sse, sleep, pipe operations
- Multi-line data handling in SSE events
- Custom error handler support
- Client disconnect detection via on_abort callback
- Integrated with both Picoev and uSockets backends
New files:
- streaming.v: Core streaming implementation
- examples/sse_demo.v: Comprehensive SSE demo with test page
- tests/test_stream_*.v: 62 property-based tests
Updated:
- picoev_server.v: PicoevStreamWriter integration
- usockets_server.v: UsocketsStreamWriter integration
- README.md: SSE streaming documentation
