In Python 3.3 threading.get_ident() has been added as a public and documented function, but there is no dummy_threading.get_ident():

    >>> import threading, dummy_threading
    >>> threading.get_ident()
    >>> dummy_threading.get_ident()
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    AttributeError: 'module' object has no attribute 'get_ident'

By the way: it may be worth to check for other possible inconsistencies between avaliable interfaces of threading and dummy_threading.

There should actually be a test to catch the inconsistencies.

dummy_threading.get_ident() works for me:

    >>> import dummy_threading as dt
    >>> dt.get_ident()
    >>> import threading
    >>> threading.get_ident()

Here is a patch to compare threading and dummy_threading modules.

A forgotten issue marked commit review.  I guess we aren't checking the commit review queue very carefully; I certainly haven't been :(.

This patch adds a test but does not fix the bug.  The assert should have a message parameter like the existing use of it in the test suite.  Lines should be wrapped at 80...the lack of wrapping in the original import has already been corrected.  Finally, the test seems more appropriate in test_dummythreading than test_threading.

> This patch adds a test but does not fix the bug.

I forgot to explain what the first patch does. The specific problem reported by OP has already been fixed in default branch (but not in 3.5) so issue18858.diff was added a test to make sure that threading and dummy_threading API are in sync.

dummy_threading.currentThread() and dummy_threading.activeCount() still don't work in both 3.5 and default branches so we basically need two different patches. I'm attaching a patch for 3.5.

dummy_threading was removed in Python 3.9 with issue37312 . I hope this issue can be closed as outdated.
