Hi,
I wanted to try out python-gevent. First, I have started with updating
the packages to the newest greenlet and gevent. And there is a problem:
a greenlet test fails with an error:
> PYTHONPATH=build/lib.linux-i686-2.7 python benchmarks/chain.py
> python: Objects/object.c:2453: _PyTrash_thread_deposit_object: Assertion
> `((((((((PyObject*)(op))->ob_type)))->tp_flags & ((1L<<14))) != 0) &&
> ((((PyObject*)(op))->ob_type)->tp_is_gc == ((void *)0) ||
> (((PyObject*)(op))->ob_type)->tp_is_gc(op)))' failed. Result:Aborted
The test works when I limit the number of greenlets in chain (from the
default 100000) to 33 or less:
> [jajcus@jajo greenlet]$ PYTHONPATH=build/lib.linux-i686-2.7 python
> benchmarks/chain.py -n 33
> Result: 33
> 0.000419 seconds
According to Google no one else has such a problem.
I have tried different greenlet versions, compiled with different
compilation
flags. All greenlet versions > 0.4.0 fail in a similar way.
python-greenlet-0.3.1, when patched as it used to be in our RPM doesn't
fail, but current gevent requires newer greenlet and no one else seems
to use similar patches for newer greenlet versions.
Current python3-greenlet, built from the same source, but for Python3
works.
It seems our python package is broken – maybe some compiler flag is
causing problems, but I have no idea how to further debug this.
Any ideas?
Greets,
Jacek
