2009-06-21python: Make all CppOwnedPyObjects and similar support garbage collection.Julian Andres Klode1-4/+5
If you want to subclass apt_pkg.Cache() and create an apt_pkg.DepCache() object in it (e.g. as self.depcache) this is needed because otherwise, Python would not know about the cyclic dependency and refuse to free any of them. This also changes apt_pkg.Cache to the standard deallocation schema, because the underlying CacheFile deletes its pointers automatically on deletion. Thus a second call is not needed.
2009-06-12Bugfix: Delete pointers correctly, fixing memory leaks. (LP: #370149)Julian Andres Klode1-1/+1
We previously called the destructor of the pointer. This resulted in no object using pointers being deallocated. This patch introduces CppDeallocPtr() and CppOwnedDeallocPtr() which do the same as the other CppDealloc() and CppOwnedDealloc(), but use 'delete' on the pointer instead of the deconstructor. Furthermore, this patch also changes AcquireFile to be a CppOwnedPyObject, owned by the Acquire object. Without this change, deleting the Acquire object would cause a crash when AcquireFile is deallocated.
