libuv关闭tcp server时需要执行的API

需要执行的接口有两个：

uv_shutdown

uv_close

 

具体用法见官方源码：test-shutdown-close.c

https://github.com/libuv/libuv/blob/v1.x/test/test-shutdown-close.c#L57

#include "uv.h"
#include "task.h"


static uv_shutdown_t shutdown_req;
static uv_connect_t connect_req;

static int connect_cb_called = 0;
static int shutdown_cb_called = 0;
static int close_cb_called = 0;


static void shutdown_cb(uv_shutdown_t* req, int status) {
  ASSERT(req == &shutdown_req);
  ASSERT(status == 0 || status == UV_ECANCELED);
  shutdown_cb_called++;
}


static void close_cb(uv_handle_t* handle) {
  close_cb_called++;
}


static void connect_cb(uv_connect_t* req, int status) {
  int r;

  ASSERT(req == &connect_req);
  ASSERT(status == 0);

  r = uv_shutdown(&shutdown_req, req->handle, shutdown_cb);
  ASSERT(r == 0);
  ASSERT(0 == uv_is_closing((uv_handle_t*) req->handle));
  uv_close((uv_handle_t*) req->handle, close_cb);
  ASSERT(1 == uv_is_closing((uv_handle_t*) req->handle));

  connect_cb_called++;
}


TEST_IMPL(shutdown_close_tcp) {
  struct sockaddr_in addr;
  uv_tcp_t h;
  int r;

  ASSERT(0 == uv_ip4_addr("127.0.0.1", TEST_PORT, &addr));
  r = uv_tcp_init(uv_default_loop(), &h);
  ASSERT(r == 0);
  r = uv_tcp_connect(&connect_req,
                     &h,
                     (const struct sockaddr*) &addr,
                     connect_cb);
  ASSERT(r == 0);
  r = uv_run(uv_default_loop(), UV_RUN_DEFAULT);
  ASSERT(r == 0);

  ASSERT(connect_cb_called == 1);
  ASSERT(shutdown_cb_called == 1);
  ASSERT(close_cb_called == 1);

  MAKE_VALGRIND_HAPPY();
  return 0;
}


TEST_IMPL(shutdown_close_pipe) {
  uv_pipe_t h;
  int r;

  r = uv_pipe_init(uv_default_loop(), &h, 0);
  ASSERT(r == 0);
  uv_pipe_connect(&connect_req, &h, TEST_PIPENAME, connect_cb);
  r = uv_run(uv_default_loop(), UV_RUN_DEFAULT);
  ASSERT(r == 0);

  ASSERT(connect_cb_called == 1);
  ASSERT(shutdown_cb_called == 1);
  ASSERT(close_cb_called == 1);

  MAKE_VALGRIND_HAPPY();
  return 0;
}
