Resolver fails to keep 2nd level dependencies that use optional packages when performing "update"

I am on the latest Poetry version.
I have searched the issues of this repo and believe that this is not a duplicate (see comment below with possible linked issues).
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).
OS version and name: macOS 10.15.5
Poetry version: 1.0.9, 1.0.10, 1.1.0b2
Link of a Gist with the contents of your pyproject.toml file: See commands below

Issue

There is an inconsistency between the install and update commands when it comes to resolving dependencies of packages that require themselves a package with extras.

Consider the following minimal example:

tsfresh depends on dask[dataframe]
dask[dataframe] depends on fsspec and partd

$ poetry new test_proj
$ cd test_proj
$ poetry install
$ poetry add tsfresh  # here everything gets installed as it should
$ poetry update  # here fsspec and partd are removed (together with locket because partd depends on it)

I must say that I found old issues that seem to be similar but since this is a very critical bug, I chose to open a new issue for visibility anyway. Also, it seems mine is more general than these:

#2300
#2494
#2080

Here are the logs of both commands:

install

  - Removing grpcio (1.29.0)

@hauntsaninja

I'm hitting this in a very similar situation to @hauntsaninja , also with grpcio being the affected package, though note that in both my and their case this only involves the poetry add command, not update as per the OP.

My case is, adding firebase-admin to an empty Poetry project adds the necessary dependencies, including grpcio.

If I then add google-cloud-logging, it incorrectly removes grpcio.

For what it's worth both packages have google-api-core[grpc] in their install_requires.

https://github.com/firebase/firebase-admin-python/blob/f43e6876684d2c7e9acf5b0b013642b44883c63a/setup.py#L41

https://github.com/googleapis/python-logging/blob/6dde25ef6f279947cd55a8a3b7300ae1f84afa4e/setup.py#L32

To reproduce:

Create a new directory
poetry init , accept all defaults
poetry add firebase-admin - note that grpcio is installed
poetry add google-cloud-logging - note that grpcio is incorrectly removed.

This is with:

poetry==1.0.9
python==3.7.7 (set using pyenv local 3.7.7)
firebase-admin==4.3.0
google-cloud-logging==1.15.0

I can also confirm that and I agree this is a major issue.

Could be a duplicate of #1609

We are affected by this as well.

We've also been affected by this. Loss of time + now having to circumvent the issue.

Thank you for fixing this! Looking at those PRs, I'm glad I gave up on trying to fix this myself :-)

@vbersier Can you please try the fix at #3147.

Using pipx

pipx install --suffix=@3147 'poetry @ git+https://github.com/python-poetry/poetry.git@refs/pull/3147/head'

Using a container (podman | docker)

podman run --rm -i --entrypoint bash python:3.8 <<EOF
set -e
python -m pip install -q git+https://github.com/python-poetry/poetry.git@refs/pull/3147/head
python -m poetry new foobar
pushd foobar
sed -i /pytest/d pyproject.toml
python -m poetry add tsfresh
python -m poetry run python -c 'from dask import dataframe'
EOF

This also fixes my very weird 2nd level dependencies error. Thanks, hope it gets released soon, wasted a night trying to debug it :(
