我正在嘗試爲tcpip設置異步I/O的升壓測試。升壓測試和異步IO:在地址的內存訪問衝突:在故障地址沒有映射
我的函數來發送TCP消息:
int TcpClient::sendMsgToServer(string msg) {
if (isConnected == true) {
Logger::debug("Asynch send request for msg: " + msg, __LINE__,
__FILE__);
sendSequence++;
msg.append("\r\n");
int length = msg.length() + 2; //+2 is for \r\n
char* buffer = (char*) msg.c_str();
Logger::debug(buffer, __LINE__, __FILE__);
m_Socket.async_send(boost::asio::buffer(buffer, length),
boost::bind(&fingigcc::TcpClient::sendMsgToServerErrorHandler,
this, boost::asio::placeholders::error,
boost::asio::placeholders::bytes_transferred));
std::string sentMsg = "Sent Msg: " + msg;
Logger::debug(sentMsg, __LINE__, __FILE__);
return 0;
} else {
return -1;
}
}
void TcpClient::sendMsgToServerErrorHandler(
const boost::system::error_code& error, std::size_t bytes_transferred) {
Logger::debug("Sending complete: ", __LINE__, __FILE__);
sendResponseSequence++;
int i = error.value();
std::stringstream ss;
ss.clear();
ss << i;
Logger::debug("RESULTCODE: " + ss.str(), __LINE__, __FILE__);
if (i == 0) {
Logger::debug("RESULT: " + error.message(), __LINE__, __FILE__);
} else {
Logger::crit(error.message(), __LINE__, __FILE__);
m_Socket.close();
isConnected = false;
connectionStateChanged(isConnected);
}
}
現在此功能工作正常,如果我只是在主線程中運行(不運行做升壓試驗)
我升壓測試功能看起來像這樣的:
BOOST_AUTO_TEST_CASE(CommunicationCore_sendTcpIpMsg_test) {
CommunicationCoreFixture f;
int compare = f.c->initializeTcpIpConnection(serverAddress, serverPort); // i initialize the connection here. runs fine with any issue
sleep(2);
compare = f.c->sendMsgToServer("IDENTIFY console-2");
BOOST_MESSAGE("Sending returned value : " << compare);
BOOST_CHECK(compare == 0);
}
和失敗,出現以下錯誤:
Entering test case "CommunicationCore_sendTcpIpMsg_test"
unknown location(0): fatal error in "CommunicationCore_sendTcpIpMsg_test": memory access violation at address: 0x01003255: no mapping at fault address
*****************Test is aborted
有什麼我應該知道,而測試這樣的異步功能?
我的生成信息:
Platform: linux

STL : GNU libstdc++ version 20120920
Boost : 1.49.0
編輯:
我曾嘗試通過以下方式修改它well..but仍然得到同樣的錯誤:
int TcpClient::sendMsgToServer(string msg) {
if (isConnected == true) {
Logger::debug("Asynch send request for msg: " + msg, __LINE__,
__FILE__);
sendSequence++;
msg.append("\r\n");
char *buffer = new char[msg.size() + 1];
buffer[msg.size()] = 0;
memcpy(buffer, msg.c_str(), msg.size());
Logger::debug(buffer, __LINE__, __FILE__);
m_Socket.async_send(boost::asio::buffer(buffer, (msg.size() + 1)),
boost::bind(&fingigcc::TcpClient::sendMsgToServerErrorHandler,
this, boost::asio::placeholders::error,
boost::asio::placeholders::bytes_transferred));
std::string sentMsg = "Sent Msg: " + msg;
Logger::debug(sentMsg, __LINE__, __FILE__);
return 0;
} else {
return -1;
}
}
'CommunicationCoreFixture'的默認構造函數是否確保其'c'成員指向一個有效的對象? –
是的。事實上,我應該提到,如果我刪除零件: m_Socket.async_send(boost :: asio :: buffer(buffer,length), boost :: bind(&fingigcc :: TcpClient :: sendMsgToServerErrorHandler, this,boost :: asio :: placeholders :: error, boost :: asio :: placeholders :: bytes_transferred));它運行沒有問題。 –
