question about memory mgmt

Baloo

Hi!


Are all Ice objects managed? I mean, assuming that I call Ice::Initialize at the beginning of main(), and destroy at the end, all Ice data should be deleted properly upon exiting, shouldn't they? I ask because the VS.NET 2003 shows some memory leaks, however my reference counters indicate the the classes I wrote were cleaned up nicely.

The object dump is the following:

Object dump complete.

The initialization code is the following:

	Ice::PropertiesPtr properties = Ice::createProperties(argc, argv);
	properties->load("pathfinder.cfg");
	IObject::ic = Ice::initializeWithProperties(argc, argv, properties);

NetManager:

		Ice::ObjectAdapterPtr adapter = 
			IObject::ic->createObjectAdapterWithEndpoints("DManagerAdapter", ""); 

		adapter->add(this, Ice::stringToIdentity("DManager")); 
		adapter->activate(); 

... and NetEnvironment:

		Ice::ObjectAdapterPtr adapter = 
			IObject::ic->createObjectAdapterWithEndpoints("DEnvironmentAdapter", ""); 

		adapter->add(this, Ice::stringToIdentity("DEnvironment")); 
		adapter->activate(); 

The upper two sections are called in the constructors of two different classes. The adapters are stored as private members. Apart from calling waitforShutdown, the upper code is pretty much the same as that of the demos...
After finishing the constructors, the program basically just waits for an ESC and then cleans up:

		delete server;
		IObject::ic->destroy();
		IDummy* tmp = new IDummy();
		delete tmp;
		exit(0);

The server class holds a NetEnvironment and a NetManager instance. The IDummy does nothing but prints the reference counters into a logfile.

Any ideas?

Thanks in advance,

Hi,

You can ignore these leak warnings from Visual Studio. We have investigated these reports in the past and found that they correspond to static instances of std::string that do not get destroyed before the leak checker reports these messages.

We realize that it's annoying to see these messages, but we haven't found a good workaround for them yet.

Take care,
- Mark

Wow you're fast!

Thanks for the answer,
