Issues with Drupal core 10.1

The version of google-cloud-php package that this module includes is "google/cloud": "^0.191" as you can see here: https://git.drupalcode.org/project/gcsfs/-/blob/1.0.x/composer.json#L18

That version of google-cloud-php package requires "psr/http-message": "1.0.*", as you can see here: https://github.com/googleapis/google-cloud-php/blob/v0.191.0/composer.js...

The latest version of google-cloud-php package requires "psr/http-message": "^1.0|^2.0", as you can see here: https://github.com/googleapis/google-cloud-php/blob/v0.213.0/composer.js...

Looking into the composer documentation, because in my mind composer should choose the latest version (0.213), but there is some explicit language around pre-1.0 versions that is the root of the issue. Because the version of the google-cloud-php package is 0.191.0 and 0.213.0 and the composer json file is using caret notation it's essentially locking the version to 0.191.0 when my intention was to set it to between 0.191.0 and 1.0.0. The caret notation does not work that way but can be accomplished with the tilde notation "google/cloud": "~0.213".

Apologies for the explanation, writting it down has helped me to keep it straight.

I'll play around with the composer config for the module to see if what I've outlined above will work. Stay tuned.

Testing the update uncovers another issue:

$ composer require 'drupal/gcsfs:1.0.x-dev@dev'

./composer.json has been updated
Running composer update drupal/gcsfs
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - drupal/core-recommended is locked to version 10.1.1 and an update of this package was not requested.
    - drupal/gcsfs dev-1.0.x requires google/cloud ~0.213 -> satisfiable by google/cloud[v0.213.0].
    - google/cloud v0.213.0 conflicts with psr/log >=3.
    - drupal/gcsfs 1.0.x-dev is an alias of drupal/gcsfs dev-1.0.x and thus requires it to be installed too.
    - drupal/core-recommended 10.1.1 requires psr/log ~3.0.0 -> satisfiable by psr/log[3.0.0].
    - Root composer.json requires drupal/gcsfs 1.0.x-dev@dev -> satisfiable by drupal/gcsfs[1.0.x-dev (alias of dev-1.0.x)].

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Unfortunately there is no version of google-cloud-php that can use psr/log and can also use psr/http-message:^1.1 or ^2.0.

In the meantime I need to lock this to Drupal core 10.0.

Updated the dependency from google/cloud (entire google cloud PHP SDK) to the google/cloud-storage package only. Added a beta4 release with this fix.
