Backoff (sleep) if http 429 code is returned

[baracudda]

Issue Kind

Brand new capability

Description

• I have a project with 50+ dependencies and github.com is set as the primary source priority. However, poetry starts to encounter 429 responses from github after about 30 GET requests within a second or three. When watching with -vvv, poetry clearly does not wait and instead continues retrying the URL until 5 attempts all result in a 429 and crash out of the install command (or lock). Please respect the 429 response.

Impact

if 429 is not respected, installation or lock operations cannot succeed, ever.

Workarounds

github.com cannot be set as "primary" priority

[dimbleby]

github.com is set as the primary source priority

What does this mean? Github is not a python package repository.

Please provide the details that the issue template asks for, and a way to reproduce whatever it is you are seeing

[baracudda]

[[tool.poetry.source]]
name = "github"
url = "https://github.com"
priority = "primary"

[dimbleby]

yeah, that just wont work. Again: github is not a python package repository.

Please close
