ACE_Asynch_Connector应用的问题
ACE的DEMO程序有些问题：如下：
int AIO_CLD_Connector::validate_connection
(const ACE_Asynch_Connect::Result& result,
const ACE_INET_Addr &remote, const ACE_INET_Addr&) {
remote_addr_ = remote;
if (!result.success ()) {
ACE_Time_Value delay (retry_delay_);
retry_delay_ *= 2;
if (retry_delay_ > MAX_RETRY_DELAY)
retry_delay_ = MAX_RETRY_DELAY;
proactor ()->schedule_timer (*this, 0, delay);
return -1;
}
retry_delay_ = INITIAL_RETRY_DELAY;
if (ssl_ctx_ == 0) {
OpenSSL_add_ssl_algorithms ();
ssl_ctx_ = SSL_CTX_new (SSLv3_client_method ());
if (ssl_ctx_ == 0) return -1;
if (SSL_CTX_use_certificate_file (ssl_ctx_,
CLD_CERTIFICATE_FILENAME,
SSL_FILETYPE_PEM) <= 0
|| SSL_CTX_use_PrivateKey_file (ssl_ctx_,
CLD_KEY_FILENAME,
SSL_FILETYPE_PEM) <= 0
|| !SSL_CTX_check_private_key (ssl_ctx_)) {
SSL_CTX_free (ssl_ctx_);
ssl_ctx_ = 0;
return -1;
}
ssl_ = SSL_new (ssl_ctx_);
if (ssl_ == 0) {
SSL_CTX_free (ssl_ctx_); ssl_ctx_ = 0;
return -1;
}
}
SSL_clear (ssl_);
#if defined (ACE_WIN32)
// ACE_WIN32 is the only platform where ACE_HANDLE is not an int.
// See ace/config-lite.h for the typedefs.
SSL_set_fd (ssl_, reinterpret_cast<int> (result.connect_handle ()));
#else
SSL_set_fd (ssl_, result.connect_handle ());
#endif /* ACE_WIN32 */
SSL_set_verify (ssl_, SSL_VERIFY_PEER, 0);
if (SSL_connect (ssl_) == -1
|| SSL_shutdown (ssl_) == -1) return -1;
return 0;
}
void AIO_CLD_Connector::handle_time_out
(const ACE_Time_Value&, const void *) {
connect (remote_addr_);
}
这段程序的本意，是在socket建立连接成功后，进行SSL的验证，如果连接失败，调用定时器重新连接。
但问题在红色标注的部分，如果第一次连接失败了，则这个地址是不确定的(文档说明)，实际我测试，是0.0.0.0:0。
这样以来，其实是陷入了死循环，永无止境了。
