Allow path dependency that is missing build-system #675

oysols · 2023-12-16T17:55:27Z

Missing [build-system] table should be allowed.
Poetry handles this fine, except for this check.

Tools should not require the existence of the [build-system] table.

per the PEP, the correct check for supports_pep517 would be

If the pyproject.toml file is absent, or the build-backend key is missing, the source tree is not using this specification

the section that you quote relates to PEP518's build-system, not PEP517's build-backend

oysols · 2023-12-16T22:06:49Z

I agree. This implements the simplified solution to this issue. The alternative would be deep validation of the toml file.

radoering · 2023-12-17T14:46:07Z

I still don't understand what kind of problem you're trying to solve. Is it just that the name of the method does not match the current implementation or is there a deeper issue? (Afaik, a path dependency without a build system (and no setup.py/setup.cfg) is not installable from Poetry's point of view and thus is not supported so maybe we should just rename the method to is_installable_python_project()?)

Further, the following message is now even more outdated than before:

poetry-core/src/poetry/core/packages/dependency.py

Lines 407 to 411 in 56c0376

 if not is_python_project(Path(name)): 

 raise ValueError( 

 f"Directory {name!r} is not installable. File 'setup.[py|cfg]' " 

 "not found." 

 )

A path dependency without a build system IS installable by Poetry, but this check blocked the installation. I tried to describe the issue with the new test case. As I read the spec (as linked earlier) that pyproject.toml should be valid and installable.

dimbleby · 2023-12-17T15:01:24Z

indeed according to pip's reading, even an empty pyproject.toml is enough to define an installable package:

$ pip install .

A path dependency without a build system IS installable by Poetry

Ah, of course it is since setuptools supports pyproject.toml. 🤦

Then, this makes sense of course and we should only change the error message I have already mentioned in #675 (comment).

indeed according to pip's reading, even an empty pyproject.toml is enough to define an installable package:

Weird...
