The reactor loop exited prematurely (`has_handles && active_event_count > 0` → false) while file I/O callbacks were still pending, causing deadlocks in async file writes (e.g. `CURLOPT_FILE` with async I/O). Fixed by adding `ZEND_ASYNC_INCREASE_EVENT_COUNT` after successful `uv_fs_*` submission and `ZEND_ASYNC_DECREASE_EVENT_COUNT` in their completion callbacks (`io_file_read_cb`, `io_file_write_cb`, `io_file_flush_cb`, `io_file_stat_cb`). - **Generator segfault in fiber-coroutine mode**: Generators running inside fiber coroutines were not marked with `ZEND_GENERATOR_IN_FIBER` because `EG(active_fiber)` is not set in coroutine mode. This caused shutdown destructors to close generators while the coroutine was still suspended, leading to a NULL `execute_data` dereference in `zend_generator_resume`. Fixed by also checking `ZEND_ASYNC_CURRENT_COROUTINE` with `ZEND_COROUTINE_IS_FIBER` when setting the `IN_FIBER` flag on generators. ### Added diff --git a/libuv_reactor.c b/libuv_reactor.c index e3c2a55e..00a123a8 100644 --- a/libuv_reactor.c +++ b/libuv_reactor.c @@ -3333,6 +3333,7 @@ static void io_file_read_cb(uv_fs_t *fs_request) req->base.completed = true; uv_fs_req_cleanup(fs_request); + ZEND_ASYNC_DECREASE_EVENT_COUNT(&io->base.event); ZEND_ASYNC_CALLBACKS_NOTIFY(&io->base.event, &req->base, req->base.exception); IF_EXCEPTION_STOP_REACTOR; } @@ -3353,6 +3354,7 @@ static void io_file_write_cb(uv_fs_t *fs_request) req->base.completed = true; uv_fs_req_cleanup(fs_request); + ZEND_ASYNC_DECREASE_EVENT_COUNT(&io->base.event); ZEND_ASYNC_CALLBACKS_NOTIFY(&io->base.event, &req->base, req->base.exception); IF_EXCEPTION_STOP_REACTOR; } @@ -3372,6 +3374,7 @@ static void io_file_flush_cb(uv_fs_t *fs_request) req->base.completed = true; uv_fs_req_cleanup(fs_request); + ZEND_ASYNC_DECREASE_EVENT_COUNT(&io->base.event); ZEND_ASYNC_CALLBACKS_NOTIFY(&io->base.event, &req->base, req->base.exception); IF_EXCEPTION_STOP_REACTOR; } @@ -3395,6 +3398,7 @@ static void io_file_stat_cb(uv_fs_t *fs_request) req->base.completed = true; uv_fs_req_cleanup(fs_request); + ZEND_ASYNC_DECREASE_EVENT_COUNT(&io->base.event); ZEND_ASYNC_CALLBACKS_NOTIFY(&io->base.event, &req->base, req->base.exception); IF_EXCEPTION_STOP_REACTOR; } @@ -3635,6 +3639,7 @@ static zend_async_io_req_t *libuv_io_read(zend_async_io_t *io_base, const size_t return NULL; } + ZEND_ASYNC_INCREASE_EVENT_COUNT(&io->base.event); return &req->base; } @@ -3734,6 +3739,7 @@ static zend_async_io_req_t *libuv_io_write(zend_async_io_t *io_base, const char return NULL; } + ZEND_ASYNC_INCREASE_EVENT_COUNT(&io->base.event); return &req->base; } @@ -3822,6 +3828,7 @@ static zend_async_io_req_t *libuv_io_flush(zend_async_io_t *io_base) return NULL; } + ZEND_ASYNC_INCREASE_EVENT_COUNT(&io->base.event); return &req->base; } @@ -3905,6 +3912,7 @@ static zend_async_io_req_t *libuv_io_stat(zend_async_io_t *io_base, zend_stat_t return NULL; } + ZEND_ASYNC_INCREASE_EVENT_COUNT(&io->base.event); return &req->base; } diff --git a/run-tests.sh b/run-tests.sh index 27f69edd..ad766b68 100755 --- a/run-tests.sh +++ b/run-tests.sh @@ -16,4 +16,4 @@ else TEST_PATH="$BASE_PATH/$1" fi -"$PHP_EXECUTABLE" "$RUN_TESTS_PATH" --show-diff -m -p "$PHP_EXECUTABLE" "$TEST_PATH" +"$PHP_EXECUTABLE" "$RUN_TESTS_PATH" --show-diff -p "$PHP_EXECUTABLE" "$TEST_PATH" diff --git a/tests/curl/012-write_file_basic.phpt b/tests/curl/012-write_file_basic.phpt new file mode 100644 index 00000000..55e91d92 --- /dev/null +++ b/tests/curl/012-write_file_basic.phpt @@ -0,0 +1,52 @@ +--TEST-- +Async curl_write: CURLOPT_FILE downloads response to file +--EXTENSIONS-- +curl +--FILE-- +port}/"); + curl_setopt($ch, CURLOPT_FILE, $fp); + curl_setopt($ch, CURLOPT_TIMEOUT, 5); + + $result = curl_exec($ch); + $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); + $error = curl_error($ch); + + unset($ch); + fclose($fp); + + echo "curl_exec returned: " .

Supports `cancelPending` parameter (default: `true`) that controls whether coroutines spawned inside the callback are cancelled or awaited after iteration completes. - **`Async\FileSystemWatcher` class**: Persistent filesystem watcher with `foreach` iteration support, suspend/resume on new events, two storage modes (coalesce with HashTable deduplication, raw with circular buffer), `close()`/`isClosed()` lifecycle, and `Awaitable` interface via `ZEND_ASYNC_EVENT_REF_FIELDS` pattern.

When set, `zend_get_executed_filename_ex()`, `zend_get_executed_lineno()`, and `get_active_function_name()` in `Zend/zend_execute_API.c` fall back to the coroutine's suspended `execute_data` for file, line, and function name. Zero-cost: the execute_data is only read when an error actually occurs. Macros: `ZEND_ASYNC_ACTING_COROUTINE`, `ZEND_ASYNC_ACT_AS_START(coroutine)`, `ZEND_ASYNC_ACT_AS_END()`. ### Changed - **Bailout handling**: Added `ZEND_ASYNC_EVENT_F_BAILOUT` flag (bit 11) on `zend_async_event_t`.

Fix: pass offset=-1 to uv_fs_write/uv_fs_read so libuv uses regular write()/read() which move the kernel file offset. Update tracked offset from kernel position via lseek(SEEK_CUR) after completion.

WriteFile+OVERLAPPED (explicit offset) does not advance the kernel file position, so lseek(SEEK_CUR) in the write callback returns a stale value. Fix: use arithmetic offset update for append mode. Also simplified libuv_io_create: removed the fstat-based offset init for append files — plain_wrapper.c now seeks to EOF on Windows before creating the IO handle, so lseek(SEEK_CUR) returns the correct position on all platforms. --- libuv_reactor.c | 50 ++++++++++++++++++++++++++++--------------------- 1 file changed, 29 insertions(+), 21 deletions(-) diff --git a/libuv_reactor.c b/libuv_reactor.c index 5c24b762..82d80332 100644 --- a/libuv_reactor.c +++ b/libuv_reactor.c @@ -3361,12 +3361,18 @@ static void io_file_write_cb(uv_fs_t *fs_request) if (fs_request->result >= 0) { req->base.transferred = (ssize_t) fs_request->result; - /* Update tracked offset from kernel position. */ - const zend_off_t pos = lseek(io->crt_fd, 0, SEEK_CUR); - if (pos >= 0) { - io->handle.file.offset = pos; - } else { + +#ifdef PHP_WIN32 + /* When an explicit offset was passed to uv_fs_write (append mode), + * WriteFile+OVERLAPPED does not advance the kernel file position, + * so lseek(SEEK_CUR) would return a stale value. */ + if (io->base.state & ZEND_ASYNC_IO_APPEND) { io->handle.file.offset += fs_request->result; + } else +#endif + { + const zend_off_t pos = lseek(io->crt_fd, 0, SEEK_CUR); + io->handle.file.offset = (pos >= 0) ? pos : io->handle.file.offset + fs_request->result; } } else { req->base.transferred = -1; @@ -3526,18 +3532,11 @@ libuv_io_create(const zend_file_descriptor_t fd, const zend_async_io_type type, io->handle.udp.data = io; } else { - /* FILE type */ - if (state & ZEND_ASYNC_IO_APPEND) { - zend_stat_t st; - if (zend_fstat(io->crt_fd, &st) == 0 && st.st_size > 0) { - io->handle.file.offset = st.st_size; - } else { - io->handle.file.offset = 0; - } - } else { - const zend_off_t pos = zend_lseek(io->crt_fd, 0, SEEK_CUR); - io->handle.file.offset = (pos >= 0) ? pos : 0; - } + /* FILE type — use the current kernel file position. + * For append mode on Windows, plain_wrapper.c already called + * _lseeki64(fd, 0, SEEK_END) to match Unix O_APPEND behavior. */ + const zend_off_t pos = zend_lseek(io->crt_fd, 0, SEEK_CUR); + io->handle.file.offset = (pos >= 0) ? pos : 0; } return &io->base; @@ -3735,11 +3734,20 @@ static zend_async_io_req_t *libuv_io_write(zend_async_io_t *io_base, const char const uv_buf_t write_buffer = uv_buf_init((char *) buf, (unsigned int) count); req->fs_req.data = req; - /* Use offset=-1 so libuv calls write() instead of pwrite(). - * This moves the kernel file offset, which is essential when - * multiple fds share the same open file description (e.g. dup/redirect). */ + /* offset=-1 tells libuv to use write() instead of pwrite(), which + * advances the kernel file offset — important for dup'd descriptors. + * + * On Windows the CRT _O_APPEND flag is invisible to WriteFile(), + * so we pass the tracked end-of-file offset explicitly. */ +#ifdef PHP_WIN32 + const int64_t offset = (io->base.state & ZEND_ASYNC_IO_APPEND) + ?

Removing `FILE_WRITE_DATA` would fix atomic append but breaks `ftruncate`/`SetEndOfFile`. Concurrent append from multiple coroutines remains a known limitation (test 069 marked XFAIL). - **Reactor deadlock on pending file I/O requests**: `uv_fs_read`, `uv_fs_write`, `uv_fs_fsync`, and `uv_fs_fstat` are libuv requests (not handles) that keep `uv_loop_alive()` true but were invisible to `ZEND_ASYNC_ACTIVE_EVENT_COUNT`. The reactor loop exited prematurely (`has_handles && active_event_count > 0` → false) while file I/O callbacks were still pending, causing deadlocks in async file writes (e.g. `CURLOPT_FILE` with async I/O). Fixed by adding `ZEND_ASYNC_INCREASE_EVENT_COUNT` after successful `uv_fs_*` submission and `ZEND_ASYNC_DECREASE_EVENT_COUNT` in their completion callbacks (`io_file_read_cb`, `io_file_write_cb`, `io_file_flush_cb`, `io_file_stat_cb`). - **Generator segfault in fiber-coroutine mode**: Generators running inside fiber coroutines were not marked with `ZEND_GENERATOR_IN_FIBER` because `EG(active_fiber)` is not set in coroutine mode. This caused shutdown destructors to close generators while the coroutine was still suspended, leading to a NULL `execute_data` dereference in `zend_generator_resume`. Fixed by also checking `ZEND_ASYNC_CURRENT_COROUTINE` with `ZEND_COROUTINE_IS_FIBER` when setting the `IN_FIBER` flag on generators. diff --git a/libuv_reactor.c b/libuv_reactor.c index 2e6643d5..f2d0611f 100644 --- a/libuv_reactor.c +++ b/libuv_reactor.c @@ -3351,7 +3351,7 @@ static void io_file_read_cb(uv_fs_t *fs_request) req->base.transferred = (ssize_t) fs_request->result; if (fs_request->result > 0) { /* Update tracked offset from kernel position. */ - const zend_off_t pos = lseek(io->crt_fd, 0, SEEK_CUR); + const zend_off_t pos = zend_lseek(io->crt_fd, 0, SEEK_CUR); if (pos >= 0) { io->handle.file.offset = pos; } else { @@ -3382,13 +3382,13 @@ static void io_file_write_cb(uv_fs_t *fs_request) #ifdef PHP_WIN32 /* When an explicit offset was passed to uv_fs_write (append mode), * WriteFile+OVERLAPPED does not advance the kernel file position, - * so lseek(SEEK_CUR) would return a stale value. */ + * so zend_lseek(SEEK_CUR) would return a stale value. */ if (io->base.state & ZEND_ASYNC_IO_APPEND) { io->handle.file.offset += fs_request->result; } else #endif { - const zend_off_t pos = lseek(io->crt_fd, 0, SEEK_CUR); + const zend_off_t pos = zend_lseek(io->crt_fd, 0, SEEK_CUR); io->handle.file.offset = (pos >= 0) ? pos : io->handle.file.offset + fs_request->result; } } else { @@ -3549,11 +3549,20 @@ libuv_io_create(const zend_file_descriptor_t fd, const zend_async_io_type type, io->handle.udp.data = io; } else { - /* FILE type — use the current kernel file position. - * For append mode on Windows, plain_wrapper.c already called - * _lseeki64(fd, 0, SEEK_END) to match Unix O_APPEND behavior. */ - const zend_off_t pos = zend_lseek(io->crt_fd, 0, SEEK_CUR); - io->handle.file.offset = (pos >= 0) ? pos : 0; + /* FILE type: initialise the tracked offset. + * For append mode we need to know the current EOF so that + * uv_fs_write can target it explicitly (on Windows _O_APPEND + * is a CRT flag invisible to WriteFile).

However, the original fd was lost because stdiop_cast unconditionally set data->fd = SOCK_ERR. On Windows this caused the file to remain locked after fclose (Permission denied on reopen/unlink).

Any code accessing the object after ZEND_ASYNC_IO_CLOSE would hit use-after-free (e.g. dispose() in php_stdiop_close, causing segfault with USE_ZEND_ALLOC=0). Fix: use refcount to manage async_io_t lifetime. libuv_io_close adds a ref before uv_close, io_close_cb calls dispose which decrements it. The object is only freed when refcount reaches 0, ensuring all users have released their references. --- libuv_reactor.c | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) diff --git a/libuv_reactor.c b/libuv_reactor.c index dcba9be2..eb72b3fc 100644 --- a/libuv_reactor.c +++ b/libuv_reactor.c @@ -3247,11 +3247,7 @@ static bool libuv_io_event_dispose(zend_async_event_t *event) zend_async_callbacks_free(event); - /* STREAM types: uv_close is async, pefree happens in io_close_cb. - * FILE type: no uv handle, free immediately. */ - if (!ZEND_ASYNC_IO_IS_STREAM(io->base.type) && io->base.type != ZEND_ASYNC_IO_TYPE_UDP) { - pefree(io, 0); - } + pefree(io, 0); return true; } @@ -3344,7 +3340,8 @@ static void io_pipe_write_cb(uv_write_t *write_request, int status) static void io_close_cb(uv_handle_t *pipe_handle) { - pefree(pipe_handle->data, 0); + async_io_t *io = (async_io_t *) pipe_handle->data; + io->base.event.dispose(&io->base.event); } /* }}} */ @@ -3849,10 +3846,12 @@ static bool libuv_io_close(zend_async_io_t *io_base) if (ZEND_ASYNC_IO_IS_STREAM(io->base.type)) { uv_read_stop(&io->handle.stream); io->handle.stream.data = io; + ZEND_ASYNC_EVENT_ADD_REF(&io->base.event); uv_close((uv_handle_t *) &io->handle.stream, io_close_cb); need_close_handle = true; } else if (io->base.type == ZEND_ASYNC_IO_TYPE_UDP) { io->handle.udp.data = io; + ZEND_ASYNC_EVENT_ADD_REF(&io->base.event); uv_close((uv_handle_t *) &io->handle.udp, io_close_cb); need_close_handle = true; } From af9e1dbb3473b92329a282660b9f0f18ddd6a149 Mon Sep 17 00:00:00 2001 From: Edmond <1571649+EdmondDantes@users.noreply.github.com> Date: Wed, 11 Mar 2026 06:30:41 +0000 Subject: [PATCH 61/72] =?UTF-8?q?#96:=20Fix=20flaky=20CI=20tests=20?= =?UTF-8?q?=E2=80=94=20poll=20loop=20for=20pipe=20read,=20accept=20any=20c?= =?UTF-8?q?lient=20exit=20code?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- .../io/046-nonblocking_pipe_read_with_data.phpt | 16 +++++++++++----- .../024-stream_select_remote_disconnect.phpt | 2 +- 2 files changed, 12 insertions(+), 6 deletions(-) diff --git a/tests/io/046-nonblocking_pipe_read_with_data.phpt b/tests/io/046-nonblocking_pipe_read_with_data.phpt index 36c792aa..939f69a5 100644 --- a/tests/io/046-nonblocking_pipe_read_with_data.phpt +++ b/tests/io/046-nonblocking_pipe_read_with_data.phpt @@ -29,13 +29,19 @@ $coroutine = spawn(function() { return "fail"; } - // Give child a moment to write - usleep(50000); - - // Set non-blocking, then read — data should be available + // Set non-blocking, then poll for data with retries + // (CI runners may be slow to start the child process) stream_set_blocking($pipes[1], false); - $data = fread($pipes[1], 1024); + $data = ''; + for ($i = 0; $i < 10; $i++) { + usleep(50000); // 50ms + $chunk = fread($pipes[1], 1024); + if ($chunk !== '' && $chunk !== false) { + $data = $chunk; + break; + } + } echo "read: '$data'\n"; echo "has data: " .

This is a php-src JIT bug, not async-specific.
