Drupal 9 Readiness check before June 3rd

[DiegoPino]

What? Drupal 8 is death (or will be by June 3rd.. ok it's not like that really), long live Drupal 9 (also, will be a just born one, full of bugs...so)

Yep. It took us some time, like almost 2 years from idea to what we have now and we designed Archipelago to be as compliant to Drupal 9 as we could with such a tiny team and too little time. Still, codebase has grown, we have so much good and complex too code, so we need to pass a general review on each Module we coded but also on each module we suggest should be used. This Issue will be a placeholder for this Friday, when that work will be passed. Idea is to check here what passed and open the issues needed to make the other ones pass. And then have (yes!) a 9.x-1.0 branch for our very own and of course more code to maintain... help!.

And i start today! I'm so proud of myself 🏷️
I will check SBF first and go from there.

General info here just in case someone wonders what is the status? D9 since forever!. @giancarlobi has D9 and Archipelago running live already. There are some minor changes that needed to be done (that escaped my automated deprecation check and some other contributed modules annoyances but all is well). All that went into 1.0.0-RC1 of each module. Conclusion 1.0.0-RC1 will be dual version either 8.9.5 or 9.0.4 up to you

I've done a fast quick pass on the required modules from composer.json:

  Problem 1
    - drupal/display_field_copy dev-1.x requires drupal/core ~8.0 -> found drupal/core[8.0.0-beta6, ..., 8.9.x-dev] but it conflicts with your root composer.json require (9.1.4).
    - drupal/display_field_copy 1.x-dev is an alias of drupal/display_field_copy dev-1.x and thus requires it to be installed too.
    - Root composer.json requires drupal/display_field_copy 1.x-dev -> satisfiable by drupal/display_field_copy[1.x-dev (alias of dev-1.x)].


  Problem 1
    - drupal/form_mode_manager dev-2.x requires drupal/core ^8 -> found drupal/core[8.0.0-beta6, ..., 8.9.x-dev] but it conflicts with your root composer.json require (9.1.4).
    - drupal/form_mode_manager 2.x-dev is an alias of drupal/form_mode_manager dev-2.x and thus requires it to be installed too.
    - Root composer.json requires drupal/form_mode_manager 2.x-dev -> satisfiable by drupal/form_mode_manager[2.x-dev (alias of dev-2.x)].

  Problem 1
    - drupal/key_value dev-1.x requires drupal/core ^8 -> found drupal/core[8.0.0-beta6, ..., 8.9.x-dev] but it conflicts with your root composer.json require (9.1.4).
    - drupal/key_value 1.x-dev is an alias of drupal/key_value dev-1.x and thus requires it to be installed too.
    - Root composer.json requires drupal/key_value 1.x-dev -> satisfiable by drupal/key_value[1.x-dev (alias of dev-1.x)].

  Problem 1
    - drupal/role_theme_switcher dev-1.x requires drupal/core ^8 -> found drupal/core[8.0.0-beta6, ..., 8.9.x-dev] but it conflicts with your root composer.json require (9.1.4).
    - drupal/role_theme_switcher 1.x-dev is an alias of drupal/role_theme_switcher dev-1.x and thus requires it to be installed too.
    - Root composer.json requires drupal/role_theme_switcher 1.x-dev -> satisfiable by drupal/role_theme_switcher[1.x-dev (alias of dev-1.x)].


  Problem 1
    - drupal/webform_entity_handler dev-1.x requires drupal/core ^8 -> found drupal/core[8.0.0-beta6, ..., 8.9.x-dev] but it conflicts with your root composer.json require (9.1.4).
    - drupal/webform_entity_handler 1.x-dev is an alias of drupal/webform_entity_handler dev-1.x and thus requires it to be installed too.
    - Root composer.json requires drupal/webform_entity_handler 1.x-dev -> satisfiable by drupal/webform_entity_handler[1.x-dev (alias of dev-1.x)].

Modules allegedly incompatible with Drupal 9:

• display_field_copy: Version 2.0.0 is compatible with Drupal 9. It seems it only has the compatibility fixes https://git.drupalcode.org/project/display_field_copy/-/compare/8.x-1.x...2.x
• form_mode_manager: No D9 version, a patch in the way but maintainer seems to be away https://www.drupal.org/project/form_mode_manager/issues/3164478. I've contacted him via drupal.org but no dice.
• key_value: No D9 version but a patch proposed https://www.drupal.org/project/key_value/issues/3186113. Main maintainer should be reachable.
• role_theme_switcher: No D9 version, patch proposed: https://www.drupal.org/project/role_theme_switcher/issues/3148659. Maintainers inactive but I can reach one of them very easily.
• webform_entity_handler: No D9 version but I have full control of this one :)

This is great @pcambra. display_field_copy 2.0.0 is nice, I was not even aware of it. Form mode manager is a larger issue, we may try to ask for maintenance roles there if there is no movement or take over some of the functionality into webform_strawberryfield

[DiegoPino]

Also the webform_entity_handler is something we really do not need for any standard implementation. We may explore it again in the near future (or in a call!) and helps a lot you are in charge!!!

role_theme_switcher: we may either roll with a single theme better OR explore alternative modules.
