Custom memory manager

[Carl Bevil]

Hello all. If I want to use a custom memory manager to, say, track memory
allocations in Python, what's the best way to do this? I seem to remember
there being a way in version 1.5 (or so -- been a while since I used it). I
didn't see anything in the documentation, but I may have missed it.

I've got the Python source code (v2.3.3) embedded in my application (which is
in C++), and would like to somehow override Python's default memory
allocators. Is there an easy or "accepted" way to do this?

Thanks!

Carl

Re: Custom memory manager


We have done some experiments with the memory manager in Python 2.3+.
Not to replace it but to obtain more detailed and accurate statistics
for the memory usage.

One thing to keep in in mind is that not all memory in a Python
application is managed by the Python memory manager. Objects may be
allocated by direct calls to malloc() and then passed to the Python
memory manager to be freed. The Python memory manager handles that
scenario properly.

While replacing the Python manager is possible, be prepared for some
surprises. It all depends on the actual modules used in your Python
application and how those modules allocate objects.
