Looks like you're misunderstanding how lstrip() works. It removes characters from the left as long as they are in the argument, which is surely not what you meant. (Ditto for rstrip() but in this case it's harmless.)

Ah, you are right. Apologies. The rstrip should be fine (removing trailing newlines is what I want), but the lstrip I can replace with a slice. Thanks!

The AppVeyor failure is a flake. |
|
Also, I have a change set for #3895 but it modifies testpythoneval (to allow for filtering of test names), so it is blocked by this. |
|
OK I've restarted the failing build. |

I am a little surprised that this still flaked the same way. Is that because it was run without the benefit of #4048?

Hm. I don't like blindly clipping. Please use a regular for-loop that inspects the start of each line before stripping the temp directory and separator.
This is because the change still uses subprocesses to evaluate the Python files. I have a change set to disable the python2eval tests that will make it go away, it is just waiting on this. |

I am not 100% sure I believe the story about the AppVeyor tests (this would imply that the problem was always about the subprocess running the Python code rather than the subprocess running mypy) but at this point I am willing to try anything to stop the bleeding, so I'm merging now. |
This is a re-do of #4025.
This change moves the mypy checking of the eval files away from subprocesses, instead using
mypy.api.It also increases the timeout of the
runfunction in an attempt to fix #3543.
