Utility for dumping memory usage stats.

This is tailored to mypy and knows (a little) about which list objects are owned by particular AST nodes, etc.

Function collect​_memory​_stats Return stats about memory use.
Function find​_recursive​_objects Find additional objects referenced by objs and append them to objs.
Function print​_memory​_profile Undocumented
def collect_memory_stats(): (source)

Return stats about memory use.

Return a tuple with these items:
  • Dict from object kind to number of instances of that kind
  • Dict from object kind to total bytes used by all instances of that kind
Returns
Tuple[Dict[str, int], Dict[str, int]]Undocumented
def find_recursive_objects(objs): (source)

Find additional objects referenced by objs and append them to objs.

We use this since gc.get_objects() does not return objects without pointers in them such as strings.

Parameters
objs:List[object]Undocumented
def print_memory_profile(run_gc=True): (source)

Undocumented

Parameters
