Python 3.9.0 warning
|
||||||
|
^^^^^^^^^^^^^^^^^^^^
|
||||||
|
|
||||||
|
Combining older versions of pybind11 (< 2.6.0) with Python on 3.9.0 will
|
||||||
|
trigger undefined behavior that typically manifests as crashes during
|
||||||
|
interpreter shutdown (but could also destroy your data. **You have been
|
||||||
|
warned**).
|
||||||
|
|
||||||
|
This issue has been
|
||||||
|
`fixed in Python <https://github.com/python/cpython/pull/22670>`_. As a
|
||||||
|
mitigation until 3.9.1 is released and commonly used, pybind11 (2.6.0 or newer)
|
||||||
|
includes a temporary workaround specifically when Python 3.9.0 is detected at
|
||||||
|
runtime, leaking about 50 bytes of memory when a callback function is garbage
|
||||||
|
collected. For reference; the pybind11 test suite has about 2,000 such
|
||||||
|
callbacks, but only 49 are garbage collected before the end-of-process. Wheels
|
||||||
|
built with Python 3.9.0 will correctly avoid the leak when run in Python 3.9.1.
