lifetime: circular dependency

[bari12]

Hi
I find a import problems about /opt/rucio/lib/rucio/tests/test_lifetime.py
This test will send request to trigger lib/rucio/web/rest/lifetime_exception.py
but it seems a circular import occurs in this .py ?
 

(.venv) [root@rucio-test03 rucio]# python -i lib/rucio/web/rest/lifetime_exception.py
Traceback (most recent call last):
  File "lib/rucio/web/rest/lifetime_exception.py", line 17, in <module>
    from rucio.api.lifetime_exception import list_exceptions, add_exception, update_exception

  File "/opt/rucio/lib/rucio/core/lock.py", line 27, in <module>
    from rucio.core.lifetime_exception import define_eol
ImportError: cannot import name define_eol

 
In python shell:
 

>>> import rucio.core.lifetime_exception
