crash: free(): invalid pointer #414

hazcod · 2021-05-17T14:44:51Z

Very odd, but I have a Docker container on Apple Silicon (M1) which crashes when I import google.cloud.
It works when I remove the import line.

Environment details

OS type and version: python:3.9.5-slim-buster on Docker
google-cloud-pubsub version: 2.8.6

Steps to reproduce

from google.cloud import pubsub_v1

Code example

Stack trace

free(): invalid pointer

I can reproduce this (and no k8s required) on a M1 MBP.

@hazcod observed a fault when importing google.cloud.pubsub_v1 as above;

# strace python3 -c 'from google.cloud import pubsub_v1'

But importing google.cloud.pubsub_v1 isn't really required here; the fault can be reproduced with importing only these two dependencies...

python3 -c 'import proto.message, grpc;'
free(): invalid pointer
Aborted

Importing either by itself doesn't crash. Further, importing them in the other order doesn't crash. I do not understand why.

python3 -c 'import grpc, proto.message; print(grpc, proto.message)'
<module 'grpc' from '/usr/local/lib/python3.9/site-packages/grpc/__init__.py'> <module 'proto.message' from '/usr/local/lib/python3.9/site-packages/proto/message.py'>

Opened up https://bugs.python.org/issue44161

plamut · 2021-05-17T22:06:50Z

This sounds like an external issue in one of the dependencies. It's the first time I'm seeing this, thanks for the report!

@lidizheng Is this issue familiar? Can you reproduce it as reported?
(basically trying to narrow it down to either proto-plus or grpcio)

@hazcod Can you please also share the versions of the proto-plus and grpcio dependencies used in the check? Or better yet, the entire pip freeze output? Thanks!

lidizheng · 2021-05-17T22:16:16Z

Crashing depending on the import order of grpcio and protobuf has happened before: grpc/grpc#24897. The quick fix is try to upgrade both grpcio and protobuf to in-sync, it's grpcio==1.37.1 grpcio-tools=1.37.1 protobuf==3.15.2.

CC @gnossen who found the ABI incompatibility in the first place.

EDIT: can not reproduce with macOS 11.3.1 + 3.7.9, here is the pip freeze: https://gist.github.com/lidizheng/391d0eb5f8be52ced2d259c9f806ee82

gnossen · 2021-05-17T23:05:27Z

The quick fix is try to upgrade both grpcio and protobuf to in-sync,

Actually, this issue should be fixed, regardless of protobuf version.

@alanjcastonguay Some questions for you:

What version of grpcio do you have installed?
Does this issue still occur if you update to the latest version of grpcio? (1.37.1)
Do you have grpcio-tools installed as well? Or just grpcio? If both, please try upgrading grpcio-tools as well.
If you do have grpcio-tools installed, try removing it. Does the issue persist?

If upgrading doesn't fix the issue for you, please help me generate a symbolized core dump. Install grpcio (and grpcio-tools) using our nightly builds, which do not have symbols stripped.

gnossen · 2021-05-17T23:15:03Z

I just noticed that this is in Docker on Mac M1, not x86 Mac OS, which the fix was for. Can you confirm which artifacts you're downloading? Is it grpcio-1.37.1-cp39-cp39-manylinux2014_aarch64.whl? These aarch64 artifacts are brand new. If this is the problematic artifact, then it's likely that a very similar issue to the one fixed by grpc/grpc#24992 is at fault here.

Using only grpcio-1.39.0 + grpcio_tools-1.39.0 + proto_plus-1.18.1 (+ six-1.16.0 + protobuf-3.17.0, which are pulled in as dependencies).

I can install gdb inside that same container and grab a backtrace, though I've no idea how to get the inner python bits or what you might be looking for.

I've no idea how to get the inner python bits or what you might be looking for.

Yeah, I need to figure out what's wrong with my gdb setup to effectively debug this, but what you just posted is super helpful on it's own. This line in particular is telling:

#15 0x0000ffff879273e0 in __static_initialization_and_destruction_0 (__initialize_p=1, __priority=65535)

It looks like the problem has to do with static variable initialization/destruction.

@jtattermusch is probably better equipped to reproduce/debug at this point.

plamut · 2021-05-18T05:17:16Z

@gnossen Thanks for jumping in and the research so far!

Should we transfer this issue to grpcio, as it's not directly related to PubSub, the latter just uses grpcio as a dependency?

OTOH it would still be good to keep it here for visibility, and if you guys don't mind tracking it here, I'm also fine with it.

hazcod · 2021-05-18T06:05:24Z

Thank you all for co-debugging! I've opened up grpc/grpc#26279 to the best of my knowledge.
Please chime in there in case I missed something.

hazcod · 2021-05-19T12:07:43Z

Curiously, is there a workaround for now to use python-pubsub on M1?
Freezing pip to: (?)

grpcio==1.37.1 grpcio-tools=1.37.1 protobuf==3.15.2

ellieayla · 2021-05-19T12:43:16Z

One workaround appears to be: import in this order:

import grpc
import proto.message
from google.cloud import pubsub_v1

jtattermusch · 2021-06-08T05:26:06Z

The issue has now been fixed in grpc/grpc#26279.
The will be in the next grpc-python release (1.39.x) and in the next patch release of 1.38.x.

plamut · 2021-06-08T07:25:58Z

@jtattermusch This sounds great, thanks!

plamut · 2021-06-28T15:10:59Z

This has been fixed and release in grpcio 1.38.1. Will update the version pin.
