Need a way to set a global PyPI repo URL for all project manually.

Feature Request

Hello everyone, I’m a python developer live in Mainland China. As well known the network connection is so bad in my country that we cannot connect to the official PyPI repo directly sometimes. So most of us usually some PyPI mirrors in our region (like https://mirrors.aliyun.com/pypi/simple/, it’s deployed by AlibabaCloud) to get a fast and stabilizing network connection. PIP gives us a way to set the index globally using pip config set global.index-url . But I cannot find related config items in Poetry. Okay, I know what you want to say, I know I can set repo info in my pyproject.toml like this.

[[tool.poetry.source]]
name = "aliyun"
url = "https://mirrors.aliyun.com/pypi/simple/"
default = true

But it will cause some tricky problems. If I have some workmates in other countries, they don’t need repo mirrors to speed up service, even it will make them cannot use PyPI repo (thanks to stupid GFW), or we need to use Github Action as our CI service, they all don’t need this config item. So I think the PyPI repo URL should not as a project config in my project repo, we need a way to set in our dev environment and use it for all projects. Thank you.

@dev-techmoe I can definitely appreciate your situation and I do agree that there are various cases where you would want to use a mirror instead of public pypi index.

Poetry has some hard-coded assumptions about PyPI. This means taht simply setting a url for PyPI will not work. The assumptions include (but not limited to), the use of the JSON endpoint to get package metadata, There is no guarentee that this exists for all mirrors. We need to,

1. Allow for poetry to be confired with first-class knowledge of PyPI mirrors.
2. Improve legacy repository support to ensure that we detect “true” legacy repos (ie, without json endpoints).
3. With these changes, we should be able to safely configure mirror urls and identify if they are warehouse compatible and be smart about what endpoints we use.

For this issue we should keep generic environment specific overrides out of scope; but only focus on supporting PyPI mirrors for an environment.
