Project's name interferes with resolution logic

When attempting to add or sync a dependency to a project, if the dependency depends on a package whose name matches the name in your pyproject.toml, resolution fails.

Create the following pyproject.toml

[project]
name = "dagster"
version = "0.0.0"
description = "Add your description here"
requires-python = ">=3.12"

Run uv add dagster-webserver --verbose (dagster-webserver depends on dagster)

log.txt (too big to paste)

Changing the name in pyproject.toml makes it work correctly.

Running on macOS 14.6.1 (23G93), with uv 0.4.9 (Homebrew 2024-09-10)

I think it's correct to fail here.

I wasn't sure either. I guess it wasn't immediately obvious why the resolution was failing, which led me to dig further.

We could add a note about this somewhere. Is the error message helpful?

The error got me confused at first because I did not understand why the dependency I was adding was depending on my project.

Because only the following versions of dagster-webserver are available:
          dagster-webserver>=1.3.14,<=1.4.12
          dagster-webserver>=1.4.13,<=1.5.13
          dagster-webserver>=1.5.14,<=1.7.1
          dagster-webserver>=1.7.2,<=1.7.8
          dagster-webserver>=1.7.9
      and dagster-webserver==1.3.14 depends on your project, we can conclude that all of:
          dagster-webserver<1.4.0
          dagster-webserver>1.4.12,<1.4.13
          dagster-webserver>1.5.13,<1.5.14
          dagster-webserver>1.7.1,<1.7.2
          dagster-webserver>1.7.8,<1.7.9

and dagster-webserver==1.3.14 depends on your project

I see okay thanks! I think we can do better there.

A possible solution here is that we'd add a "hint" after a resolution error (we have some infrastructure for this) if the project name shadows the name of a package available in the index. I'm not sure if we'll have checked if the package is available though.

Another (perhaps easier to implement) solution is to hint if a dependency of the project depends on the project itself e.g. here dagster-webserver is a dependency of the project and depends on the project.

As a side note related to uv add, the dependency resolution error message is overly verbose in part because it reports details about all available versions, at once.
Manually asking the resolver to pick the "currently latest available" version results in a much a shorter and direct output:

$ uv add 'dagster-webserver==1.8.7'
  × No solution found when resolving dependencies:
  ╰─▶ Because dagster-webserver==1.8.7 depends on your project and your project depends
      on dagster-webserver==1.8.7, we can conclude that your project's requirements are unsatisfiable.
  help: If this is intentional, run `uv add --frozen` to skip the lock and sync steps.

Oof yeah here's the whole error message.

I think there's another problem here. Like we should collapse these and say "all versions of dagster-webserver depend on your project" instead of enumerating each version. I can look into that... probably hard.

Provide resolution hints in case of possible local name conflicts (#7505

Sorry, I'm not sure to understand the issue here, which I experience too.

Locally, with uv 0.4.20, I'm able to install my dependencies. Yet in CI, with the same version, 0.4.20, I'm getting this error:

 Using CPython 3.12.7 interpreter at: /opt/hostedtoolcache/Python/3.12.7/x64/bin/python
Creating virtual environment at: .venv
  × No solution found when resolving dependencies:
  ╰─▶ Because only the following versions of griffe-inherited-docstrings are
      available:
          griffe-inherited-docstrings<=1.0.0
          griffe-inherited-docstrings==1.0.1
      and griffe-inherited-docstrings==1.0.0 depends on your project, we can
      conclude that griffe-inherited-docstrings>=1.0.0,<1.0.1 depends on your
      project.
      And because griffe-inherited-docstrings==1.0.1 depends on your project,
      we can conclude that griffe-inherited-docstrings>=1.0.0 depends on your
      project.
      And because griffe:dev depends on griffe-inherited-docstrings>=1.0 and
      your project depends on griffe:dev, we can conclude that your project's
      requirements are unsatisfiable.

      hint: The package `griffe-inherited-docstrings` depends on the package
      `griffe` but the name is shadowed by your project. Consider changing the
      name of the project.

The only difference between local and CI is that in CI I pass --no-editable to uv sync, yet passing this same flag locally works fine (even after removing uv.lock and .venv).

Does this hint mean that cyclic dependencies are not supported 🤔? I think it's pretty common for plugins/extensions to specify the main project as dependency (django-apps specify their accepted django versions, mkdocs plugins their accepted mkdocs versions, griffe extensions their accepted griffe versions, etc.), and then if the main project starts depending on a plugin/extension, it creates kind of a cyclic dependency (actual example: mkdocs depends on mkdocstrings to render API docs, and mkdocstrings specifies its accepted mkdocs versions), but I think it resolved fine previously.

Changing project names is not possible, and removing the griffe dep spec from griffe-inherited-docstrings is definitely not wanted either. Yet griffe requires griffe-inherited-docstrings to build its docs... So, what should I do here 🫠?

Hmmm, looks like it's working again in CI 🤷 I'll let you know if I encounter the issue again 🙂

Spoke too fast:

No dependency changes. Is it because the two first are on a tagged commit but not the last one O_o?

Still cannot reproduce locally so none of this will be very helpful for you 🙇

Can confirm it works fine when CI is triggered by pushing a tag.

Here's what I gather:

when installing deps (in non-editable mode) at an untagged commit
uv builds my project A with version x.y.z.devN+ghash
then wants to install A@x.y.z.devN+ghash, as well as B which depends on A>=x.y.z
and it gets confused about the version of A to install 🤷
