DeprecationWarning: ABCs Collection #20434
Description
NOTE: Spack still functions as intended. I simply want to report the deprecation warning.
I wrote a spack-python script to do some cleanup/setup of spack files in between runs. I wrote a few unittests for my script, and when I ran them, I got these deprecation warnings:
tests/test_cleanup.py::test_SpackCleanup::test_compiler_find
spack/lib/spack/llnl/util/lang.py:267: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.9 it will stop working

Steps to reproduce the issue
The script is rather long, so I'll give you a piece of it:
def spack_compiler_find():
"""
Enable spack to find compilers.
"""
from spack.main import SpackCommand
compiler = SpackCommand('compiler')
compiler('find')
logger.info("'spack compiler find' has been triggered.")
The test:
import unittest
from .cleanup import spack_compiler_find
import os
import shutil
class test_SpackCleanup(unittest.TestCase):
@classmethod
def setUpClass(cls):
if not os.path.isdir(os.path.expanduser('~/.spack')):
os.mkdir(os.path.expanduser('~/.spack'))
@classmethod
def tearDownClass(cls):
if os.path.isdir(os.path.expanduser('~/.spack')):
shutil.rmtree(os.path.expanduser('~/.spack'))
def test_compiler_find(self):
spack_compiler_find()
self.assertTrue(os.path.isdir(os.path.expanduser('~/.spack')))
