Unhelpful errors for projects in root directory

[brandon-leapyear]

• Poetry version: 1.3.1
• Python version: 3.11
• OS version and name: ubuntu
• pyproject.toml: see below

• I am on the latest stable Poetry version, installed using a recommended method.
• I have searched the issues of this repo and believe that this is not a duplicate.
• I have consulted the FAQ and blog for any relevant entries or release notes.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

Repro: running docker build . with this Dockerfile shows an unhelpful "tuple index out of range" error:

FROM python:3.11

RUN curl -sSL https://install.python-poetry.org | python3 -
ENV PATH=/root/.local/bin:$PATH
RUN poetry --version
RUN poetry init
RUN poetry install

Seems to happen when packages is not specified in pyproject.toml and poetry tries to automatically add an Include that has a glob pattern ., which is an invalid glob:

>>> list(Path("/").glob("."))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.8/pathlib.py", line 1139, in glob
    selector = _make_selector(tuple(pattern_parts), self._flavour)
  File "/usr/local/lib/python3.8/pathlib.py", line 463, in _make_selector
    pat = pattern_parts[0]
IndexError: tuple index out of range

ah seems to only happen when running in the root directory / and without a name specified (as is the case with poetry init). So perhaps not high priority.

Also, there's another error when using poetry init --dependency=click in the root directory:

  Unable to parse fact: fact:  depends on click (^8.1.3)

  at ~/.local/share/pypoetry/venv/lib/python3.11/site-packages/poetry/puzzle/provider.py:840 in debug

Another way to reproduce tuple index out of range coming from pathlib is to run poetry on this pyproject.toml. See #8113 for full stack traces.

[tool.poetry]
name = ""
version = "0.0.0"
description = ""
authors = []

[tool.poetry.dependencies]
python = "^3.8"

presumably can be fixed by adding a pattern to the schema, preventing empty strings - at https://github.com/python-poetry/poetry-core/blob/0749c5531d778a07788dfdc163716523fd479d9e/src/poetry/core/json/schemas/poetry-schema.json#L13
