5.3.3 breaks `lazy_fixture` pattern

[trendelkampschroer]

First of all thanks a lot for the creation of pytest and all the work that is going into it!

This is the problem I have observed:

pytest-5.3.3 breaks usage of lazy_fixture parametrisation that was working with pytest-5.3.2

pytest: 5.3.3 (conda-forge)
pytest-lazy-fixture: 0.6.2
os: macos catalina
python: 3.6.7

import pytest
from pytest_lazyfixture import lazy_fixture


@pytest.fixture
def foo():
    return "foo"

@pytest.fixture
def bar():
    return "bar"

@pytest.fixture(params=[
    lazy_fixture("foo"),
    lazy_fixture("bar")
])
def myfixture(request):
    return request.param

def test_foo_bar(myfixture):
    assert myfixture in ["foo", "bar"]

This fails with the following error

  @pytest.fixture(params=[
      lazy_fixture("foo"),
      lazy_fixture("bar")
  ])
  def myfixture(request):
E       recursive dependency involving fixture 'foo' detected

duplicate of #6512 and #6492 - fixed in #6496 and soon to be released

Thx for the quick reply.

/cc @SalmonMode maybe this help you investigating, since it appears to be easily reproducible (although with another plugin still).

@blueyed thanks for the CC. I've never used lazy_fixture before, so I'll have to dig into it a bit, but this issue is separate from the one found in #6492

[blueyed]

@SalmonMode yeah, thought so myself. I think you/we should go through all the issues being closed off as duplicates maybe too quickly - #6492 appears to be a meta issue for everything this has caused a regression of some kind.

Another idea is to list all issues in #6492 itself for book keeping (I mean in the first post, in a separate section).

@nicoddemus is this resolved these days?
