Create a connection can block for up to 4 mins under Linux when TCP socket
connect() times out
----------------------------------------------------------------------------------------------
Key: AMQCPP-168
URL: https://issues.apache.org/activemq/browse/AMQCPP-168
Project: ActiveMQ C++ Client
Issue Type: Improvement
Components: CMS Impl
Affects Versions: 2.1.3
Environment: CentOS 4
Reporter: Olivier Langlois
Assignee: Nathan Mittler
Fix For: 2.2
With the following code:
{
// Create a ConnectionFactory
std::auto_ptr<cms::ConnectionFactory> pConnectionFactory(
cms::ConnectionFactory::createCMSConnectionFactory( uri
) );
m_pConnection.reset(pConnectionFactory->createConnection());
m_pConnection->start();
}
The call to createConnection() will block for up to 4 mins if the URI is a TCP
address pointing to an unreachable host.
In my application, the time out interval is way too long. I would like to have
it set to around 5 sec to 10 seconds.
I could take care of the fix if you want as all that would be needed is make
the socket non blocking only for the connect() call and manage the time out
with a select(). The only indication I would need is how you ActiveMQ cms
architects/designers would like the timeout specified to the API.
Using a new property (ie: "connect-timeout")
hardcoding a small timeout value in TcpSocket
etc...
