Description Karolina Surma 2025-05-20 11:36:03 UTC 
python-crick fails to build with Python 3.14.0b1.

This report is automated and not very verbose, but we'll try to get back here with details.

crick/tests/test_space_saving.py::test_merge_algorithm[s111-s211] Fatal Python error: Segmentation fault

https://docs.python.org/3.14/whatsnew/3.14.html

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.14-b1/fedora-rawhide-x86_64/09062430-python-crick/

For all our attempts to build python-crick with Python 3.14, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.14-b1/package/python-crick/

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package builds with Python 3.14:
https://copr.fedorainfracloud.org/coprs/g/python/python3.14-b1/

Let us know here if you have any questions.

Python 3.14 is planned to be included in Fedora 43.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.14.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.

I don't know if that is a Python bug, or Cython bug.

It's a memory corruption in __pyx_tp_dealloc_5crick_12space_saving_SpaceSaving() function: function generated by Cython. It's not a bug in Python.

I suppose that it's this code from crick/space_saving.pyx:
---
cdef class SpaceSaving:
    ...
    def __dealloc__(self):
        if self.summary != NULL:
            if np.PyDataType_ISOBJECT(self.dtype):
                spsv_object_free(<spsv_object_t *>self.summary)
            else:
                spsv_int64_free(<spsv_int64_t *>self.summary)
---

I suppose that it's a "use-after-free" bug. It's tedious to debug the bug, so it's hard to give more hints.

gdb traces:
---
Hardware watchpoint 6: *(void**)((PyThreadState *) 0xb2c6a8)->interp->object_state.freelists.floats.freelist

Old value = (void *) 0x0
New value = (void *) 0xffffffff

Comment 4 Victor Stinner 2025-06-12 15:29:45 UTC 
I tried but failed to debug the Cython issue. What helped me is to replace these 4 lines in setup.py to get debug symbols:
---
if True: #"--debug" in sys.argv:
    #sys.argv.remove("--debug")
    compile_args["undef_macros"] = ["NDEBUG"]
    compile_args["extra_compile_args"] = ["-O0", "-g"]
---

It's not trivial to install crick to run tests. I had to use the "hack" from the Fedora specfile:
---
$ cd crick
$ ln -s ../build/lib.linux-x86_64-cpython-314/crick/*so .
---

Otherwise, pytest doesn't find crick extensions such as crick.numpy_version.
Comment 5 Elliott Sales de Andrade 2025-06-15 01:21:23 UTC 
Good spot; commenting out that whole `__dealloc__` does fix the crash, but then the ref count leak test fails (naturally).

I tried something like this, just in case `__dealloc__` was called twice, but that did not fix it:

I reproduced this in a virtualenv and reported it upstream as https://github.com/dask/crick/issues/65.

Hello,

Please note that this comment was generated automatically by https://pagure.io/releng/blob/main/f/scripts/ftbfs-fti/follow-policy.py
If you feel that this output has mistakes, please open an issue at https://pagure.io/releng/

This package fails to install and maintainers are advised to take one of the following actions:

 - Fix this bug and close this bugzilla once the update makes it to the repository.
   (The same script that posted this comment will eventually close this bugzilla
   when the fixed package reaches the repository, so you don't have to worry about it.)

or

 - Move this bug to ASSIGNED if you plan on fixing this, but simply haven't done so yet.

or

 - Orphan the package if you no longer plan to maintain it.


If you do not take one of these actions, the process at https://docs.fedoraproject.org/en-US/fesco/Fails_to_build_from_source_Fails_to_install/#_package_removal_for_long_standing_ftbfs_and_fti_bugs will continue.
This package may be orphaned in 7+ weeks.
This is the first reminder (step 3) from the policy.

Don't hesitate to ask for help on https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/ if you are unsure how to fix this bug.

It looks like a refcounting bug.  This patch leads to a successful build.  I'm not saying that it's the correct fix, mind you.

I submitted an upstream PR to address what I believe the issue to be (explanation in the PR): https://github.com/dask/crick/pull/69.

Here is a PR for the Fedora package to add the patch, which leads to a successful Rawhide build: https://src.fedoraproject.org/rpms/python-crick/pull-request/3

If you feel that this output has mistakes, please open an issue at https://pagure.io/releng/

All subpackages of a package against which this bug was filled are now installable or removed from Fedora 43.

Thanks for taking care of it!
