py2http.sizeof

Approximate the memory an object holds, without walking more of it than a budget.

bounded_deep_sizeof is how py2http bounds the objects clients create or grow through class and instance endpoints (py2http.obj_dispatch).

Functions

bounded_deep_sizeof(obj[, limit])

Approximate memory held by obj and everything it references (containers, instance __dict__ and __slots__, what a bound method, a partial or a function's closure, attributes and defaults hold), counting each object once.

py2http.sizeof.bounded_deep_sizeof(obj, limit=None)

Approximate memory held by obj and everything it references (containers, instance __dict__ and __slots__, what a bound method, a partial or a function’s closure, attributes and defaults hold), counting each object once. Stops as soon as the total exceeds limit, so measuring costs at most about limit bytes’ worth of objects. Classes, modules and the code of functions are shared, so not counted, and neither is what classes and modules hold (class attributes, module globals), nor caches kept in C (lru_cache). Holding a bound method of another object counts that whole object, as holding the object itself would.

>>> small, big = bounded_deep_sizeof([1, 2]), bounded_deep_sizeof(list(range(1000)))
>>> small < big
True
>>> bounded_deep_sizeof(list(range(10**6)), limit=1000) > 1000
True

Return type:

int
