[jira] Created: (AMQCPP-118) Provide a way to allocate and free
with the same allocator
Provide a way to allocate and free with the same allocator
----------------------------------------------------------
Key: AMQCPP-118
URL: https://issues.apache.org/activemq/browse/AMQCPP-118
Project: ActiveMQ C++ Client
Issue Type: Improvement
Reporter: Albert Strasheim
Assignee: Nathan Mittler
Fix For: 2.1
Cross-runtime allocation and deallocation can cause problems on Windows (and maybe other platforms) where you can have code linked against more than one runtime in the same program. There should be a way to be sure that you allocate and deallocate AMQCPP objects using code linked against the same runtime (i.e. allocate and deallocate from the same heap).

-------------------------------------
We already use the beginthreadex and endthreadex for this reason.

-------------------------------------
I was wondering what other issues where going to show up, now we know :) It may be that we have to stipulate that in order to use the DLL you must ensure that you build it linked against the same Run-Time that your application is. Its not an optimal solution but I know at my previous company we did just this for the same reasons.
Aren't DLL's fun :)

The code that crashes is this:
{noformat}
if( textMessage != NULL ) {
text = textMessage->getText();
} else {
text = "NOT A TEXTMESSAGE!";
}
{noformat}
It crashes where the destructor for text is called, because it's trying to deallocate the string from the wrong heap. This doesn't make complete sense to me yet, but it doesn't look good for the mixing of runtimes.

-----------------------------------------
Timothy or Nathan, if you could get the code in place, I'll make an attempt to test it. I think that linking the AMQCPP example program against the AMQCPP DLL and against some other runtime like multi-threaded static (i.e. /MT[d] instead of /MD[d]) should cause a crash without these changes.

Timothy Bish commented on AMQCPP-118:
-------------------------------------
We should really think about how we do this as there are several classes that would require a method of destroying them if we go this route, some of which don't have an nice clean place where we can say the owner is...Session, Connection, etc
One idea I've been kicking around is to just overload the Ctor and Dtor for the classes that are exported from the CMS api, not sure this is the best thing but if it works than the usage would be transparent, which I'm a big fan of. I really don't like the idea of having to make the users remember to not just use the standard delete and instead ho find a method in some other class that they can call to destroy an CMS object.
Reading on overloading.
http://www.informit.com/guides/content.asp?g=cplusplus&seqNum=40&rl=1
Another option would be to place static Destroy methods in each of the exported classes that take a pointer to the object to delete.
And there's probably a lot of other ways we should consider as well.

-----------------------------------------
I quite like the idea of overriding new and delete. It nicely hides the fact that this is an implementation-specific issue, instead of adding more functions to the CMS API.

Somehow, I don't think we can fix this by simply changing our code, because things like std::string are still going to malfunction.

---------------------------------------
Agreed! So long as it doesn't add any other quirks for users, sounds like a much cleaner solution.

> Cross-runtime allocation and deallocation can cause problems on Windows (and maybe other platforms) where you can have code linked against more than one runtime in the same program. There should be a way to be sure that you allocate and deallocate AMQCPP objects using code linked against the same runtime (i.e. allocate and deallocate from the same heap).

---------------------------------------
If that's the case, then let's just say that we don't support a mish-mash of runtimes. Seems to be fair, especially given the fact that we don't release binaries - just source code. They have to build it themselves anyway, so they should build the dll with the same environment as their applications.
