disable-gc 0.1.0

disable_gc

Python context manager for temporarily disabling the garbage collector.

Reentrant, threadsafe, safe for use in asyncio, and prevents GC starvation.

Safe for use inside finalizers.

Usage

from disable_gc import disable_gc
with disable_gc:
    a = 1 # Doing things with GC disabled

@disable_gc
def func():
    a = 1  # GC disabled inside the function.

Notes

disable_gc does not and cannot monkey patch gc.enable(). Other threads enabling the gc in the background will leave it enabled until disable_gc is reentered once again.

Can be used as a reference for bpo-31356.
