Exclude Include combination gives wrong results

[nylocx]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Arch Linux x64 Kernel 5.14.15
• Poetry version: 1.1.11 and 1.2.0a2
• Python version: 3.9.7
• Link of a Gist with the contents of your pyproject.toml file: pyproject.toml

Issue

To setup a reproducible environment just run:

poetry new poetry-cython-demo
cd poetry-cython-demo
mkdir poetry_cython_demo/compiled
touch poetry_cython_demo/cython_code.pyx poetry_cython_demo/compiled/source.c poetry_cython_demo/compiled/source.h

and replace the pyproject.toml with the gist version.
Then run:

poetry build -vvv

The expected result is that the sdist package includes the C sources and the .pyx file and the wheel only includes the __init__.py.
The actual result is that the wheel includes the .pyx file.

❯ poetry build -vvv
…

…

As a side note, my first expectation was that include is working recursively as exclude, so I thought
{ path = "poetry_cython_demo/compiled", format = "sdist" }
would be enough, but than the result is even stranger output where sdist and wheel seam to be switched:

❯ poetry build -vvv

Hello @nylocx,

thanks for reporting. I can confirm this bug and a fix is on the way: python-poetry/poetry-core#228

Wao, that was a quick one, thanks!

I just checked in it does not work as I expected here is the result of the wheel. It still contains the pyx file. Any idea what is going wrong there? As the test looks like it should check for this.
poetry_cython_demo-0.1.0-py3-none-any.whl.tar.gz

Ok, it seems the patch is not included in poetry_core 1.07 even though it was released after the merge to master.
In which Version will this fix be included?

[nylocx]

@finswimmer I really don't want to annoy you but can you give an approximate ETA when this will land in poetry? I think it was not included in core 1.0.8
