Swoole v4.6.7 version released, bug fix version

v4.6.7 The version is mainly a bug fix version without downward incompatible changes.

In this version, the problem that Http\Response::end() method always returns true is fixed, and the default value output_buffer_size

In previous versions output_buffer_size default value 2M , due output_buffer_size restrictions, if the call end , the content needs to be sent is greater than this limit will respond to fail with an error as follows:

use Swoole\Http\Server;
use Swoole\Http\Request;
use Swoole\Http\Response;

$http = new Server('127.0.0.1', 9501);

$http->set([
    'http_compression' => false,
    'buffer_output_size' => 128 * 1024,
]);

$http->on('request', function (Request $request, Response $response) {
    assert($response->end(str_repeat('A', 256 * 1024)) === false);
    assert(swoole_last_error() === SWOOLE_ERROR_DATA_LENGTH_TOO_LARGE);
});

$http->start();

Use the above code to reproduce the error

WARNING finish (ERRNO 1203): The length of data [262144] exceeds the output buffer size[131072], please use the sendfile, chunked transfer mode or adjust the output_buffer_size

The previous solution was: use sendfile , write or adjust output_buffer_size , but in this version, output_buffer_size is increased to the maximum value of unsigned INT ( UINT_MAX )

Since version 4.5, the use of shared memory in the Worker process has been removed, and all UnixSocket pipes have been used instead, so there is no need to pre-allocate memory. output_buffer_size parameter is only a limitation, and setting it to a larger parameter will not cause additional memory usage.

At the same time, it also fixes the end that the return value of true is always 0609e583f524d0. After an error occurs in the above code, the response is not successful, and the return value is false
