tustvold opened a new issue, #3683: URL: https://github.com/apache/arrow-rs/issues/3683
**Describe the bug** <!-- A clear and concise description of what the bug is. --> PyArrowConvert calls `ArrowArray::into_raw` to convert the contents of `ArrowArray::empty` into raw pointers, it then passes these to python to populate, before passing them to `ArrowArray::try_from_raw`. This copies the memory contents and does not take ownership of the passed pointers, this appears to have been a change made in (#1449) by @viirya. The result is that the allocation of `Arc<FFI_ArrowSchema>` and `Arc<FFI_ArrowArray>` is never freed. Some of the memory leaks appear to have been fixed in https://github.com/apache/arrow-rs/pull/1878 but not the ones present in the python interface. I happen to think the `into_raw` method is extremely hard to use correctly, and I would propose removing it in favor of an interface that does not yield ownership of the pointers. **To Reproduce** <!-- Steps to reproduce the behavior: --> **Expected behavior** <!-- A clear and concise description of what you expected to happen. --> **Additional context** <!-- Add any other context about the problem here. --> -- This is an automated message from the Apache Git Service.
