Freezegun breaks isinstance() checks on existing objects. about freezegun

[schinckel]

I'm not sure. It seems that @spulec hasn't been on GitHub much lately. He's likely the only one who can merge, and push releases. It is possible to reference a git-commit in a requirements.txt: you may have to do that until he has time to merge/push.

[spulec]

Yeah, that's not great.

I'm working on a new branch (ctypes) that will solve this problem. It doesn't work with python 3 yet though. If you're using python2, it'd be great to have some people start testing that branch.

I've noticed that datetime objects created by freezegun can't be pickled:
pickle.PicklingError: Can't pickle <type 'datetime.datetime'>: it's not the same object as datetime.datetime.

Is that related to the isinstance issue described here? Seems likely.

[spulec]

Yes, most likely. You can try the ctypes branch and see if that gives you any luck.

[pnegahdar]

Any updates on this issue? The core should really return an instance of datetime...

[spulec]

Not a perfect solution, but it seems like the best one for now.

Any update on this? I'm running into this right now. The ctypes branch hasnt been touched in 5 years

[schinckel]

According to my understanding, this was fixed by the referenced commit.

[kingbuzzman]

it looks like my issue is with issubclass() / not with isinstance()

[schinckel]

It looks like there's also a __subclasscheck__. Should by fairly easy to follow the same pattern in the commit that @spulec referenced above.

How quickly can we get this merged and pushed to pypi O:)

I am also a contributor that can merge. Unfortunately I can't cut releases to pypi at this time.
