poetry 1.1.2 with enable parallel fails to find package from pypi when custom private source is set.

I am on the latest Poetry version.
I have searched the issues of this repo and believe that this is not a duplicate.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

OS version and name: Windows 10 2004 build 19041.508 (latest at the time)
Poetry version: 1.1.2 (latest at the time)
Python version: 3.9.0 (latest at the time)

after I upgraded poetry to 1.1.2, I thrilled to see how fast my installation will be. thus I removed and reinstalled pkgs with poetry update.

  Failed to build grpcio
  DEPRECATION: Could not build wheels for grpcio which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.

To no avail, this does not solved this issue .

I'm facing the same issue described here and when it also worked when the custom source is removed from pyproject.toml. The only difference is that I'm using poetry version 1.1.8,

I was able to reproduce on the following environment:
Poetry version: 1.1.8
Python version: 3.7.13

Using a pyproject.toml:

[tool.poetry]
name = "poetry-test"
version = "0.1.0"
description = "Poetry test"
authors = ["Your Name <you@example.com>"]

[tool.poetry.dependencies]
python = "^3.7"
requests = "^2.23.0"

[[tool.poetry.source]]
name = "loggi"
url = "https://pypi.lg.com/abc/"
secondary = true

[tool.poetry.dev-dependencies]

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

If I try to add a new lib, update lock file or install with the commands below I get the same error error:

@CaueP

Hi @CaueP -- you are on a very outdated version of Poetry. I cannot reproduce this on 1.2.x -- if you are able to do so, please open a new issue with a package repository that reproduces it defined/available. There is a user on Discord with a similar issue -- whichever of you manages to reproduce it second, please add your reproduction to the existing issue if it exists.

@neersighted

I was the user on Discord @neersighted referred to. My issue does not seem related to yours @CaueP, but also involves a private feed causing some problems.

I downgraded poetry to 1.1.8 to see if I could replicate your issue, but it works fine for me on Python 3.9. I cannot downgrade my Python to exactly match you unfortunately.

@CaueP

Hi @CaueP -- you are on a very outdated version of Poetry. I cannot reproduce this on 1.2.x -- if you are able to do so, please open a new issue with a package repository that reproduces it defined/available. There is a user on Discord with a similar issue -- whichever of you manages to reproduce it second, please add your reproduction to the existing issue if it exists.

The error reported doesn't happen on version 1.2.x, but I faced other issues related to setuptools and pip as noted on the version 1.2 announcement that is blocking the update to this version, so this is not a feasible solution.

I updated to the latest 1.1 version (1.1.15), but the same error still happens.

Inspired by this workaround on another issue, I changed the code on the same file to avoid raising the exception when Poetry cannot retrieve a PyPi package from a custom source and it worked as expected. The change I've made:

Current code:

poetry/poetry/repositories/legacy_repository.py

Lines 385 to 393 in 46bf7fd

    
           def _get(self, endpoint):  # type: (str) -> Union[Page, None] 
        
               url = self._url + endpoint 
        
               try: 
        
                   response = self.session.get(url) 
        
                   if response.status_code == 404: 
        
                       return 
        
                   response.raise_for_status() 
        
               except requests.HTTPError as e: 
        
                   raise RepositoryError(e)

Change on line 389 to return when the response is a 403:

    def _get(self, endpoint):  # type: (str) -> Union[Page, None]
        url = self._url + endpoint
        try:
            response = self.session.get(url)
            if response.status_code in (404, 403):
                return
            response.raise_for_status()
        except requests.HTTPError as e:
            raise RepositoryError(e)

@kristang could you try this code change to see if it works for you?

The main problem with this issue is that I'm blocked to do anything that changes poetry.lock file, because it always fails on the dependency resolution even with pre-existing packages. Do you think it's possible to make a patch with this change on version 1.1.x so we can get it fixed? I could work on this issue if needed.

You should be fine to migrate to 1.2 -- the issue is only when 'split brain' between 1.2 and 1.1. If you're having other issues relating to locking and installing setuptools/pip, that may be a new issue?

We're not planning any releases for the 1.1 branch -- the team is pretty small and we do not have the bandwidth to maintain a third branch with very very different code (and, the intention is that all fixes/changes go into master first, barring exceptional circumstances like the bad cherry-pick last week).

I would suggest evaluating 1.2 and asking for help via Discord/Discussions if there is something truly blocking you from moving over -- there are massive correctness improvements in 1.2.x, and as Poetry adopts a loose versioning-with-deprecations style ala Python in general, putting off moving to new versions for too long is liable to be painful later. We'd much rather make sure that people can stay on the current stable version and fix any blockers they encounter.
