Dear Sage team,
I have two cdef'd classes (lets call them A and B). They have some
cdef'd attributes that should be harmless, namely of type int or list
or dict. The entries of these lists/dicts may be objects of class A
though.
Let me emphasize that A and B do not rely on any external (wrapped) C-
Types. They are entirely built from int, list, dict, object. In
particular, I am not doing any nasty memory allocation.
I understood that Cython knows how to allocate and deallocate cdef'd
attributes of type int, list, dict, object etc. Hence, I expected that
I do not need to provide __del__ or __dealloc__ methods for A and B.
And I expected that it is virtually impossible to produce a memory
leak in such setting.
Nevertheless, get_memory_usage() shows that
creating an object of class B,
doing a computation "Result = B(...)", and
deleting B
results in an increased memory usage of 2.57MB per run.
What tools do you recommend to tracking that memory leak down?
Yours
Simon
