From e057b3a952b1e056b03ddf9a31fbd19c538833df Mon Sep 17 00:00:00 2001 From: Edmond <1571649+EdmondDantes@users.noreply.github.com> Date: Sat, 6 Sep 2025 14:37:56 +0300 Subject: [PATCH 01/50] #53: Refactor HTTP server to event-driven architecture with stream_select Replace per-connection coroutines with centralized event loop using stream_select() to monitor all active sockets simultaneously. Main loop now handles both new connections and existing client requests through single event monitoring, eliminating "Bad File handler" errors by proper socket lifecycle management.

Previously, closesocket() was called before poll_event cleanup, causing potential race conditions where LibUV operations could access already-closed socket descriptors. Changes: - xp_socket.c: Fix php_sockop_close() to transfer socket ownership to LibUV before disposal - xp_ssl.c: Apply same fix to php_openssl_sockop_close() with SSL-specific cleanup preserved - Move Windows async logic (shutdown/polling) before socket ownership transfer in both modules - When poll_event exists, transfer socket via poll_event->socket and ZEND_ASYNC_EVENT_SET_CLOSE_FD flag - Call poll_event dispose immediately after flag setting for proper cleanup order - libuv_reactor.c: Add libuv_close_poll_handle_cb() with cross-platform fd/socket closure - zend_async_API.h: Define ZEND_ASYNC_EVENT_F_CLOSE_FD flag for conditional descriptor closure This ensures LibUV completes all pending operations before socket closure across both socket implementations. --- libuv_reactor.c | 32 +++++++++++++++++++++++++++++++- 1 file changed, 31 insertions(+), 1 deletion(-) diff --git a/libuv_reactor.c b/libuv_reactor.c index e1643ec..fad6bae 100644 --- a/libuv_reactor.c +++ b/libuv_reactor.c @@ -195,6 +195,35 @@ static void libuv_close_handle_cb(uv_handle_t *handle) /* }}} */ +/* {{{ libuv_close_poll_handle_cb */ +static void libuv_close_poll_handle_cb(uv_handle_t *handle) +{ + async_poll_event_t *poll = (async_poll_event_t *)handle->data; + + /* Check if PHP requested descriptor closure after event cleanup */ + if (ZEND_ASYNC_EVENT_SHOULD_CLOSE_FD(&poll->event.base)) { + if (poll->event.is_socket && ZEND_VALID_SOCKET(poll->event.socket)) { + /* Socket cleanup - just close, no blocking operations in LibUV callback */ +#ifdef PHP_WIN32 + closesocket(poll->event.socket); +#else + close(poll->event.socket); +#endif + } else if (!poll->event.is_socket && poll->event.file != ZEND_FD_NULL) { + /* File descriptor cleanup */ +#ifdef PHP_WIN32 + CloseHandle((HANDLE)poll->event.file); +#else + close(poll->event.file); +#endif + } + } + + pefree(poll, 0); +} + +/* }}} */ + /* {{{ libuv_add_callback */ static void libuv_add_callback(zend_async_event_t *event, zend_async_event_callback_t *callback) { @@ -295,7 +324,8 @@ static void libuv_poll_dispose(zend_async_event_t *event) async_poll_event_t *poll = (async_poll_event_t *) (event); - uv_close((uv_handle_t *) &poll->uv_handle, libuv_close_handle_cb); + /* Use poll-specific callback for poll events that may need descriptor cleanup */ + uv_close((uv_handle_t *) &poll->uv_handle, libuv_close_poll_handle_cb); } /* }}} */ From eb54e6dd7af1115efce18ab01e47ed84a4134949 Mon Sep 17 00:00:00 2001 From: Edmond <1571649+EdmondDantes@users.noreply.github.com> Date: Sat, 13 Sep 2025 10:52:48 +0300 Subject: [PATCH 17/50] #53: Add zend_async_poll_proxy_t for FD resource optimization Implements a new poll proxy structure that allows multiple consumers to share a single zend_async_poll_event_t, reducing file descriptor and libuv handle usage.

Changes include: * scheduler.c: Optimize 7+ exception handling points including: - TRY_HANDLE_SUSPEND_EXCEPTION macro implementation - cancel_queued_coroutines() function - async_scheduler_coroutine_suspend() function - async_scheduler_dtor() cleanup * coroutine.c: Optimize save/restore pairs in: - async_coroutine_finalize() - finally_handlers_iterator_handler() * scope.c: Optimize scope completion callback exception handling * zend_common.c: Optimize zend_exception_merge() function * exceptions.c: Optimize async_extract_exception() function The optimization uses direct pointer manipulation instead of repeated EG() macro access, following the pattern: zend_object **exception_ptr = &EG(exception); zend_object **prev_exception_ptr = &EG(prev_exception); zend_exception_save_fast(exception_ptr, prev_exception_ptr); // ... code execution ... zend_exception_restore_fast(exception_ptr, prev_exception_ptr);

This commit introduces a dedicated resumed_coroutines queue that provides a more reliable approach. Changes: - Add resumed_coroutines circular buffer to module globals - Initialize resumed_coroutines queue in PHP_RINIT_FUNCTION - Track resumed coroutines in async_scheduler_coroutine_enqueue() and async_coroutine_resume() - Replace complex clean_events_for_resumed_coroutines() with simple process_resumed_coroutines() - Update scheduler_next_tick() and fiber_entry() to use new queue-based approach - Add proper cleanup in both engine_shutdown() and async_scheduler_dtor() to prevent memory leaks Benefits: - Eliminates race conditions from buffer reallocation tracking - Simplifies logic by checking queue contents instead of head pointer changes - Improves code readability and maintainability - Fixes memory leak of 8192 bytes in circular buffer allocation --- async.c | 1 + async_API.c | 1 + coroutine.c | 3 +++ php_async.h | 2 ++ scheduler.c | 50 +++++++++++++++----------------------------------- 5 files changed, 22 insertions(+), 35 deletions(-) diff --git a/async.c b/async.c index 20b7356..a2559e8 100644 --- a/async.c +++ b/async.c @@ -962,6 +962,7 @@ PHP_RINIT_FUNCTION(async) /* {{{ */ ZEND_ASYNC_INITIALIZE;
