Hello Adolf,

Another day with another interesting problem that you are bringing us :)

I do seem to be able to find things that don't work as expected don't I.

Did you try to run “python3 -m build” in the source directory of exceptiongroup and flit-scm?

That inspiration is coming from here:

https://github.com/archlinux/svntogit-community/blob/packages/python-excepti...

The day before yesterday I thought to myself maybe I should look what Arch Linux does but never followed through on it. Thanks very much for the suggestion. I will give it a go and see how it goes. I will also compare it with the python3-flit module we have because that looks to use the pypproject.toml file, although there are several environment variables defined that I am not sure how to specify for my case but will see how things go.

I am not sure whether we have the build and installer module.

We do have build but not installer. The python3-flit module seems to work without using installer, just build so will see how things go to start with only using build before looking at adding installer in as well.

Regards, Adolf.

Best, -Michael

Hi All,

I have figured out why the fuse mount stopped working with borgbackup in Core Update 173. (Bug#13076)

python3-trio was updated when python was updated to 3.10.8 and python3-trio is required by python3-pyfuse3. However the python3-trio update also added a new dependency - python3-exceptiongroup which then requires python3-flit_scm for the build of python3-exceptiongroup.

Both python3-exceptiongroup and python3-flit_scm use pyproject.toml, however python3-pyproject2setuppy fails with trying to build python3-flit_scm as it does not understand the backend definition in the pyproject.toml file.

The error message is :-

 File "/usr/lib/python3.10/site-packages/pyproject2setuppy/__main__.py", line 50, in main
 raise NotImplementedError(
 NotImplementedError: Build backend flit_scm:buildapi unknown

pyproject2setuppy is now marked as DEFUNCT due to the number of special cases in the pyproject.toml file that needed lots of work each time to update pyproject2setuppy to work again.

Does anyone have any idea how I should build flit_scm and exceptiongroup without using pyproject2setuppy.

I have done some searching but could not find anything that I could either understand or that did not require internet access to download all required dependencies.

Regards,

Adolf.

Good news. After a few varying attempts I have successfully built python3-flit_scm and python3-exceptiongroup using the python build and pip install commands.

I have then installed the addon packages on my vm testbed and confirmed that the fuse mount command works again with borgbackup.

I will look at using the python build/pip install approach on all the python modules for borgbackup as setup.py is flagged as deprecated. If that all works then I will submit a patch set for the bug fix.

Learned a lot with this bug issue. Hopefully useful for the future.

Regards, Adolf.

Okay, this sounds like good news.

I wish there wouldn’t be such massive chaos with every other language’s build system.
