Coroutine / client > se t timeout setting problem

blubbafett edited in Sun, 25 Sep 2022

The document is as follows:

The time-out control protocol client provides more fine-grained time-out control. You can set: timeout: total timeout, including connection, sending and receiving all timeouts_ Timeout: connection timeout read_ Timeout: receive timeout write_ Timeout: send timeout

use Swoole ;$ client = new CoroutineClient ( SWOOLE_ SOCK_ TCP );$ client -> set ([

'timeout' => 0.5,
'connect_timeout' => 1.0,
'write_timeout' => 10.0,
'read_timeout' => 0.5,

]);

Could you tell me about timeout and the following three XXX_ What's the relationship between timeout???

You can see from the source code

swoole_ client_ coro.cc ：

bool php_swoole_client_set(Socket *cli, zval *zset)
{
    HashTable *vht = Z_ARRVAL_P(zset);
    zval *ztmp;
    bool ret = true;

    /**
     * timeout
     */
    if (php_swoole_array_get_value(vht, "timeout", ztmp))
    {
        cli->set_timeout(zval_get_double(ztmp));
    }
    if (php_swoole_array_get_value(vht, "connect_timeout", ztmp))
    {
        cli->set_timeout(zval_get_double(ztmp), SW_TIMEOUT_CONNECT);
    }
    if (php_swoole_array_get_value(vht, "read_timeout", ztmp))
    {
        cli->set_timeout(zval_get_double(ztmp), SW_TIMEOUT_READ);
    }
    if (php_swoole_array_get_value(vht, "write_timeout", ztmp))
    {
        cli->set_timeout(zval_get_double(ztmp), SW_TIMEOUT_WRITE);
    }
    // 省略……
}

include\coroutine_ socket.h：

    /* set connect read write timeout */
    inline void 
    set_timeout(double timeout, int type = SW_TIMEOUT_ALL)
    {
        if (timeout == 0)
        {
            return;
        }
        if (type & SW_TIMEOUT_CONNECT)
        {
            connect_timeout = timeout;
        }
        if (type & SW_TIMEOUT_READ)
        {
            read_timeout = timeout;
        }
        if (type & SW_TIMEOUT_WRITE)
        {
            write_timeout = timeout;
        }
    }

Setting timeout will make connect_ timeout、read_ timeout、write_ The timeout is all set to the same value. You can then set the timeout for an operation separately.
