In #6002,
test_init_arg
andtest_init_arch
fails on Windows. The failure is caused by reading outdated offline cache format. However, we have set offline cache to off and set the offline cache directory to a new directory in the environment variables inrun_tests.py
, so this should not happen. Then, I discovered that functionpatch_os_environ_helper
which intends to remove only a few specified environment variables (excludes
) accidentally removes all the environment variables, and replaced them withcustom_environ
. This PR fixes the bug and lets it work as expected.
