Uncaught exceptions when using Unicorn concurrently
Hey! I am maintaining a downstream project that was using
2.0.1.post1
until recently. I have now upgraded to the most recent release:
2.1.4
This has gone through without problems for my test suites on but the Windows runners also report a barrage of exceptions. I can reproduce these locally and have isolated the error output below.
Very notably, I use pytest-xdist to execute these tests in parallel. These errors do not occur when the test suite is executed in a single thread. It can be reproduced with the following code:
import unittest
import unicorn as uc
import unicorn.x86_const as x86
from unicorn.unicorn import Uc
def hook_mem_error(emu: Uc, access: int, address: int, size: int, value: int):
aligned = address & ~0xFFF
alloc_size = 0
while address + size >= aligned + alloc_size:
alloc_size += 0x1000
emu.mem_map(aligned, alloc_size)
return True
def hook_mem_read(emu: Uc, access: int, address: int, size: int, value: int) -> bool:
print(F'{address:#016x} >> {value:#0{2 * size}x}')
return True
def hook_mem_write(emu: Uc, access: int, address: int, size: int, value: int) -> bool:
print(F'{address:#016x} << {value:#0{2 * size}x}')
return True

mu.emu_start(ip, 5)

Is it possible that it simply runs out of memory? We (Qiling) once had exactly the same issue and we resolved it with https://github.com/al-cheb/configure-pagefile-action
That's a good idea, thank you, but that's not it. My local setup has 64GB and I checked: The MVP I posted above doesn't even scratch the surface of that (neither does my actual test suite for that matter).
I can confirm there's a issue using emulator concurrently, even with different instances. I'm on C++ and with 2 threads running in tight fast loops, there are randomic ACCESS_VIOLATION exceptions. If I throttle the loop a little bit, exceptions disappear. This could mean that there's a race condition over shared memory between uc instances. Tested with both 2.1.4 and "master" branch
