Expected behaviour

__file__ variable is always defined in IPython

Actual behaviour

__file__ variable is available when IPython first starts, but is not available after kernel restart.

Reverting to version v2020.9.112786 fixes the problem

Steps to reproduce:

1. open VSCode
2. create new Python script (.py)
3. type print(__file__)
4. Run Selection/Current line in Python Interactive
5. Restart Jupyter kernel
6. Run Selection/Current line in Python Interactive again

Thanks for reporting it @alexbogun. That's a good catch. I could also repro it.
We'll discuss it on our next meeting.

[IanMatthewHuff]

Validated.

[alexbogun]

Unfortunately the issue is back again, could we please reopen this?

[rchiodo]

I'm reproing too.

[IanMatthewHuff]

@rchiodo I don't believe this was in the point fix. Yeah, I don't see it in the release branch. I think this is fixed, but just not live for customers yet. I was validating from our main bits.

[rchiodo]

Ah okay. Thanks. @alexbogun this will be fixed in our next stable release.

[IanMatthewHuff]

Validated via the previous validation. Will be in the next release as mentioned.
