New submission from Marat Sharafutdinov <deca...@gmail.com>:
I'm trying to build Python 3.7.2 within official CentOS 7.6.1810 image (https://hub.docker.com/_/centos) and getting the following error during testing: ====================================================================== FAIL: test_attributes (test.test_os.TestScandir) ---------------------------------------------------------------------- Traceback (most recent call last): File "/usr/src/python/Lib/test/test_os.py", line 3367, in test_attributes self.check_entry(entry, 'dir', True, False, False) File "/usr/src/python/Lib/test/test_os.py", line 3319, in check_entry os.stat(entry.path, follow_symlinks=False).st_ino) AssertionError: 28093768 != 85098458 I guess this bug applies to Docker containers in general.
