使用 Swoole
协程时,可以使用下面的方法进行调试
gdb php test.php
(gdb) source /path/to/swoole-src/gdbinit
例如 co::sleep
函数
(gdb) b zim_swoole_coroutine_util_sleep
(gdb) co_list coroutine 1 SW_CORO_YIELD coroutine 2 SW_CORO_RUNNING
(gdb) co_bt coroutine cid:[2] [0x7ffff148a100] Swoole\Coroutine->sleep(0.500000) [internal function] [0x7ffff148a0a0] {closure}() /home/shiguangqi/php/swoole-src/examples/coroutine/exception/test.php:7 [0x7ffff141e0c0] go(object[0x7ffff141e110]) [internal function] [0x7ffff141e030] (main) /home/shiguangqi/php/swoole-src/examples/coroutine/exception/test.php:10
(gdb) co_bt 1 [0x7ffff1487100] Swoole\Coroutine->sleep(0.500000) [internal function] [0x7ffff14870a0] {closure}() /home/shiguangqi/php/swoole-src/examples/coroutine/exception/test.php:3 [0x7ffff141e0c0] go(object[0x7ffff141e110]) [internal function] [0x7ffff141e030] (main) /home/shiguangqi/php/swoole-src/examples/coroutine/exception/test.php:10
(gdb) co_status stack_size: 2097152 call_stack_size: 1 active: 1 coro_num: 2 max_coro_num: 3000 peak_coro_num: 2
遍历当前进程内的所有协程,并打印调用栈。
Swoole\Coroutine::listCoroutines(): Swoole\Coroitine\Iterator
需要 4.1.0
或更高版本
返回迭代器,可使用 foreach
遍历,或使用 iterator_to_array
转为数组
use Swoole\Coroutine; $coros = Coroutine::listCoroutines(); foreach($coros as $cid) { var_dump(Coroutine::getBackTrace($cid)); }
