Description
When trying to figure out azure timeout issues, deadlock appeared to be occurring in parser code, so pyarrow
makes sense as the culprit. Seems like tests with weird input cause issues, for example some of the parse_dates
tests, or for a specific reproducer the test:
pandas/tests/io/parser/common/test_ints.py::test_outside_int64_uint64_range
On current pyarrow
I can't reproduce, but azure uses 0.17.0, with which can reproduce a deadlock (just running the command pandas/tests/io/parser/common/test_ints.py::test_outside_int64_uint64_range
) on macOS. Doesn't happen consistently, but will deadlock (to the point that need to sigkill to stop, which explains why pytest-timeout
didn't catch it).
