[JDEV] Memory Leak Problems

[Tim Sowden]

Hi,

I'm using the Jabber 'C' library code of jabberx and libxode from
jabber.org.

While running my application I notice that I am leaking memory. I
replaced malloc/free with my own malloc/free to trace the source of the
unfree'd memory. After running my app I am now able to pinpoint the
memory leak as being in the jabberx and libxode libraries altho I don't
know exactly which functions in there leak the memory.

The big leak that I have found is related to when I get a roster update
push from the server when I add/delete someone from my roster. This leak
is around 4K for everyone added/deleted from my roster so it's quite a
noticible amount of RAM. Note than I have around 30 people in my roster.

I suspect that I am not doing a proper free of something in my code that
the library allocates during parsing of the incoming XML message. So
what I am wondering is what am I responsible for freeing as an app from
those libraries.

Currently I call xmlnode_free() after every incoming event from the
server. I pass in jpacket->x or jpacket->iq depending on whether I get
an iq packet or any other packet. But do I need to free something else
in addition to this and if so, what are the rules (if any) for freeing
memory allocated by the libraries for incoming packets.

Thanks,

Tim
