Antoine Pitrou commented on ARROW-4120:
---------------------------------------
Is it specifically about Python reference leaks? I have written this set of
leak checkers for pytest:
https://github.com/dask/distributed/blob/master/distributed/pytest_resourceleaks.py
> [Python] Define process for testing procedures that check for no macro-level
> memory leaks

> Key: ARROW-4120
> URL: https://issues.apache.org/jira/browse/ARROW-4120
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Wes McKinney
> Priority: Major
> Fix For: 0.13.0
>
>
> Some kinds of memory leaks may be difficult to unit test for, and they may
> not cause valgrind errors necessarily
> I had written some ad hoc leak tests in
> https://github.com/apache/arrow/blob/master/python/scripts/test_leak.py. We
> have some more of this in ARROW-3324.
> It would be useful to be able to create a sort of "test suite" of memory leak
> checks. They are a bit too intensive to run in CI (since you may have to run
> something many iterations to see whether it leaks), but we could run them in
> a nightly build
