Same dep but with extra treated as independent

[altendky]

What did you want to do?
Here is a snipped snippet of my setup.cfg to setup the scenario. Full code is certainly also available.

[options]
install_requires =
    qtrio ~=0.4.1

[options.extras_require]
pyside2 =
    pyside2 ~=5.15
    qtrio[pyside2]

When attemping to install with the pyside2 extra, this results in pip catastrophically backtracking including downloading several copies of QTrio which are less than 0.4.1.

INFO: pip is looking at multiple versions of qtrio[pyside2] to determine which version is compatible with other requirements. This could take a while.

  Downloading qtrio-0.1.0-py3-none-any.whl (28 kB)

Changing the extra's QTrio dependency to qtrio[pyside2] ~=0.4.1 avoids the backtracking. While I can certainly understand how this could happen, it doesn't seem proper. 0.3.0 clearly won't satisfy ~=0.4.1 so it shouldn't need to be looked at at all. I think...?

Here's a Dockerfile that shows the succeeding case, failing case, and failing with pip@master. I ran it as docker build --no-cache -t foo - < Dockerfile.txt.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

[uranusjr]

The reason to this is actually the same as #8785. The resolver does “know” about qtrio~=0.4.1 when resolving qtrio[pyside2], but it does not know it should use the specifier on the extra-ed requirement.

This is difficult because the way resolution works is sort of like breaking the problem apart and try to solve each piece separately (how efficient the solution is mostly depends on how good you can break the thing apart). Extras are basically a backdoor to that, they produce things that can affect multiple pieces and make it difficult to reasonably break the problem into bite-chunk pieces in a pre-determined way.

[altendky]

I figured it was something like that. Thanks for taking the time to look this over. Not sure if you looked through my setup.cfg but I certainly do use extras extensively. It seems like a good place to stick the info and, in the case of PySide2, is the closest I have come up with to being able to describe constraints as opposed to requirements.

Anyways, the workaround isn't super hard and I know one thing to look for if I hit the backtracking again.

Thanks.

[uranusjr]

Combining this into #8785.

[altendky]

While #8785 has been closed by #9775, the issue reported here continues with pip 21.1.3. That said, it does appear to be fixed on main at least as of f37fc4c. Just documenting for the record since I was checking on it again. I haven't tracked down the commit that fixes this but thanks to the author and all others. :]

  DEPRECATION: A future pip version will change local packages to be built in-place without first copying to a temporary directory. We recommend you use --use-feature=in-tree-build to test your packages with this new behavior before it becomes the default.
   pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issues/7555.
