Bug? FileNotFound on cleanup

[jmrgibson]

Neat plugin, great docs. I'm running into the following issue, outlined below:

Scenario:

• pytest 6.0.1
• pytest-harvest 1.10.0
• pytest-xdist 2.0.0
• running via a shiv
• running multiple instances of pytest simultaneously

stacktrace:

  File "/home/builduser/.shiv/pytest_f6cdbae7-eadd-41ab-aef2-dd73926c7212/site-packages/pytest_harvest/plugin.py", line 435, in pytest_harvest_xdist_cleanup
    rmtree(self.results_path)
  File "/usr/lib/python3.7/shutil.py", line 485, in rmtree
    onerror(os.lstat, path, sys.exc_info())
  File "/usr/lib/python3.7/shutil.py", line 483, in rmtree
    orig_st = os.lstat(path)
FileNotFoundError: [Errno 2] No such file or directory: '.xdist_harvested'

How is self.results_path generated? it it unique per process? or would it be shared if I was running two copies of pytest simultaneously, thus leading to the following error?

EDIT: I should probably mention I'm only using the following hook in my root conftest.py

def pytest_sessionfinish(session):
    """ Gather all results and save them to a csv.
    Works both on worker and master nodes, and also with xdist disabled"""

    session_results_df = get_session_results_df(session)
    suffix = 'all' if is_main_process(session) else get_xdist_worker_id(session)
    session_results_df.to_csv('results_%s.csv' % suffix)
