unsafe-python
Memory-unsafe operations in pure CPython, gated behind safe context managers. No ctypes, no C extensions.
CPython 3.8 - 3.11 only.
Installation
pip install -U unsafelib
Usage
from unsafelib import Unsafe
# All unsafe ops require a context block
with Unsafe() as u:
# Get heap address of any Python object
obj = [1, 2, 3]
print(hex(u.addrof(obj))) # 0x7f2a1c3d4e80
# Read/write raw process memory
mem = u.getmem()
print(bytes(mem[u.addrof(obj):u.addrof(obj) + 32]))
# Forge a fake object from an address
clone = u.fakeobj(u.addrof(obj))
assert clone is obj
# Jump to arbitrary address (segfaults)
u.setrip(0xDEADBEEF)
# Outside the block - raises UnsafeContextError
u.getmem() # UnsafeContextError: Cannot call 'getmem' outside of an unsafe context.
