@srittau Thanks for your help! These errors have shown some common patterns so I am trying to fix them in a reasonable way.

One thing that might help: Just send a PR with just the result of scripts/create_baseline_stubs.py and maybe a bit of import cleanup. We can then build on that.

The first commit https://github.com/python/typeshed/pull/8417/commits/f14343ea24968047c74f0e0e67774fa8d6727f5e is generated by scripts/create_baseline_stubs.py and it has many errors so I try to make a commit for each file to fix them. So you mean I just need the first commit and you can build on that without error automatically?

Ah I see. The original commit indeed has lots of problems. Normally that script generates acceptable stubs, but not in this case, unfortunately. So please ignore my comment above.

But maybe the easiest solution in case of errors would be to just remove the problematic type annotation for now, if it is not an easy fix. This makes it easier for you to finish the stubs and for us to review the first version.

For now, most of my change is to convert C++ enum to Python enum since the auto script cannot express it using Python Enum class. I think this conversion should be achieved automatically in the future (will it be difficult?) since we cannot just rely on manual efforts to keep up with the latest change.

Unfortunately there are many CI checks failing here, and I don't think any of us currently have the bandwidth to help this PR pass all of our CI :(

I'm going to close this PR for now due to lack of recent activity, and to keep our list of open PRs at a manageable level. But I'm happy to reopen it if you're still interested in working on it :)
