Python 3.12 support replace imp with importlib #1
Comments

Hello @Qubitium. Thanks for bringing this up. Please find the merge-request that adds py3.12 support at https://lab.nexedi.com/nexedi/pygolang/-/merge_requests/23. Does it work for you? Kirill |

Compilation work and I believe there are no issues. Thank you! But unfortunately we are unable to test more as we found even more issues with 3.12 and pkgs such as torch 2.2. So we are sticking with 3.11 for now. |

@Qubitium notes (#1): Python 3.12 no longer support the imp module (fully deprecated) with note to use importlib as replacement. Please support python 3.12 by migrating from imp code to importlib. Thanks. and indeed, even trying to build pygolang fails on py3.12: (py312.venv) kirr@deca:~/src/tools/go/pygolang-master$ python setup.py build_ext -i Traceback (most recent call last): File "/home/kirr/src/tools/go/pygolang-master/setup.py", line 40, in <module> exec(readfile('trun'), trun) File "<string>", line 41, in <module> ModuleNotFoundError: No module named 'imp' -> Rework the code to use importlib instead, but keep using imp on py2 where there is practically no importlib functionality. /reported-by @Qubitium (github) /reviewed-by @jerome /reviewed-on https://lab.nexedi.com/nexedi/pygolang/-/merge_requests/23

Background: in 2019 in 4dc1a7f0 (tox += ThreadSanitizer, AddressSanitizer,
Python debug builds) I've added ThreadSanitizer and AddressSanitizer to our
test build matrix. That was done in order to help catching concurrency issues
while doing quality assurance and it indeed worked well(*). However AddressSanitizer
was added with disabled memory leak detection, because at that time there were
tons of various allocations done by Python itself, that were not released on
Python shutdown. So leak reporting pass was disabled to avoid huge non-pygolang
related printouts.
5 years later Pygolang is used by various projects, including in XLTE, where, in
particular, it is used to organize 100Hz polling of Amarisoft eNodeB service to
retrieve information about flows on Data Radio Bearers:
https://lab.nexedi.com/kirr/xlte/-/commit/2a016d48
https://lab.nexedi.com/kirr/xlte/-/blob/8e606c64/amari/drb.py
And everything works relatively well except that recently Joanne approached me
with reports that xamari program, that does the polling, is leaking memory.
During investigation I could manually find at least two causes of the leakage,
and, while working on a fix, discovered third type of leak. Since all those
leaks happen inside Pygolang and at, or around, C level - most of the
time not visible through python objects and so not discoverable via e.g
objgraph, it raises the need to have robust quality assurance procedures
built into maintenance process to cover not only concurrency and memory
safety issues, but also to reliably detect low-level memory leaks.
So before we start fixing any of the leakages, let's activate LeakSanitizer
(https://github.com/google/sanitizers/wiki/AddressSanitizerLeakSanitizer) to be
present during tox runs, so that whenever we run something via ASAN in the end
tested process is checked for whether anything was leaked and if yes, which
codepath was used to allocate leaked memory.
Initially I though that it would be hard to have distilled reports, the ones
without much of added noise due to leaks on python side, but it turns out that
starting from py3.11 cpython codebase was improved to release on interpreter
shutdown most of what was allocated, and so with modest suppression rules we
can distill LeakSanitizer output to come with the issues that are relevant to
pygolang itself.
That builds the foundation for making sure there are no memory leaks done by
pygolang in the follow-up patches. The next patch will fix chan leakage in
pychan_from_raw, and there will be more fixes to come later.
For now ASAN builds become broken, but that is good that we can see the issues.
Please see the appendix for current LeakSanitizer output.

(*) at that time, besides discovering longstanding race-condition in Python itself
(https://bugs.python.org/issue38106, https://github.com/python/cpython/pull/16047),
several concurrency issues were found in pygolang codebase as well:

The code of pychan_from_raw, that pychan.from_chan_X calls, was creating
pychan object and then setting pychan._ch to the specified raw channel.
But it missed that pychan.__new__ was creating full Python object, with
everything initialized - in particular with pychan._ch initialized to
another channel created by pychan.__cinit__ constructor, and so pointer
to that another channel was removed without decrefing it first. That
caused the leak of that second channel observable as the following
LeakSanitizer report when run on e.g. added test:
Direct leak of 72 byte(s) in 1 object(s) allocated from:

-> Fix it by adjusting raw chan -> py chan conversion routine to first
create uninitialized py object - with no underlying channel created at all.
Adjust pynil to use pychan_from_raw instead of duplicating its code, so
that we keep the logic and the fix only in one place.
The context where this problem was originally discovered is xamari from
XLTE where on every request new timer is created to handle request
timeout, and that timer, being Python-level object, wraps underlying
C-level timer with creating pychan wrapper of that:
https://lab.nexedi.com/kirr/xlte/-/blob/8e606c64/amari/__init__.py#L182-193
https://lab.nexedi.com/nexedi/pygolang/-/blob/6dd420da/golang/_time.pyx#L96
https://lab.nexedi.com/nexedi/pygolang/-/blob/6dd420da/golang/_time.pyx#L104
As the result on every request memory was leaked on and on.
Besides new test going ok even under LeakSanitizer, the following test
program confirms the fix:
```py
from golang import context
def main():
bg = context.background()
key = object()
while 1:
ctx = context.with_value(bg, key, 1)
main()
```
Before the patch it leaks ~ 1GB of RAM every second on my computer due
to similar raw chan -> py chan wrapping in py context.with_value
https://lab.nexedi.com/nexedi/pygolang/-/blob/6dd420da/golang/_context.pyx#L169-180
https://lab.nexedi.com/nexedi/pygolang/-/blob/6dd420da/golang/_context.pyx#L38-43
After the fix that program stays at constant RSS usage forever.

Python 3.12 no longer support the imp module (fully deprecated) with note to use importlib as replacement.
Please support python 3.12 by migrating from imp code to importlib. Thanks.
