Sources used as repositories to publish to need a different URL to sources to download from

Feature Request

Background

It's currently possible to add a repository to publish to in a pyproject.toml by declaring it as a [secondary] source and then referencing it's name as a --repository in the poetry publish command. This does work in poetry 1.4.

However the URL needed may be different to the URL required to us the same repo as a source. Eg: When using AWS codeartifact as a source, the URL ends /simple but to publish to codeartifact this needs to be removed from the URL. IE: This works:

[[tool.poetry.source]]
name = "codeartifact"
url = "https://acmecorp-1234567.d.codeartifact.eu-west-2.amazonaws.com/pypi/acmecorp/simple/"

[[tool.poetry.source]]
name = "target"
url = "https://acmecorp-1234567.d.codeartifact.eu-west-2.amazonaws.com/pypi/acmecorp/"

poetry publish --repository target 

This comment suggests that I shouldn't even be using a source to publish to but a repository defined poetry.toml and indeed this is hinted at by the documentation.

But adding it as a source to the project does work. It's hard to tell why. I don't know if:

• this a deliberate, yet undocumented feature?
• this a side effect of the way poetry sources and repositories work?
• this a depreciated feature?
• something else?

It certainly needs better documentation (#4658)

The Request

Could sources in pyproject.toml have two URLs (a push URL and a pull URL) so that repositories to available to publish to can be managed from the project instead of just each individual's workstation.

This would be particularly useful for larger organisations with more than one private PyPi repository. Would it be possible to have the configuration something like:

[[tool.poetry.source]]
name = "codeartifact"
url = "https://acmecorp-1234567.d.codeartifact.eu-west-2.amazonaws.com/pypi/acmecorp/simple/"
# Only used by poetry publish
publish_url = "https://acmecorp-1234567.d.codeartifact.eu-west-2.amazonaws.com/pypi/acmecorp/"

Start with the source configuration in pyproject.toml, the repository configuration in poetry.toml, and the repositories documentation. Trace how poetry publish --repository resolves a named source or repository, using the AWS CodeArtifact URL examples as the expected case. Done should include a clear decision on whether project sources may publish and how separate pull and push URLs are represented.
