示例1: test_undecodable_env
# 需要导入模块: import os [as 别名]
# 或者: from os import getenvb [as 别名]
def test_undecodable_env(self):
for key, value in (('test', 'abc\uDCFF'), ('test\uDCFF', '42')):
encoded_value = value.encode("ascii", "surrogateescape")
# test str with surrogates
script = "import os; print(ascii(os.getenv(%s)))" % repr(key)
env = os.environ.copy()
env[key] = value
# Use C locale to get ASCII for the locale encoding to force
# surrogate-escaping of \xFF in the child process; otherwise it can
# be decoded as-is if the default locale is latin-1.
env['LC_ALL'] = 'C'
if sys.platform.startswith("aix"):
# On AIX, the C locale uses the Latin1 encoding
decoded_value = encoded_value.decode("latin1", "surrogateescape")
else:
# On other UNIXes, the C locale uses the ASCII encoding
decoded_value = value
