Timeframe to release Symfony 6 support?

[RoSk0]

First of all thanks for all the work .

I can see that Symfony 6 support is already merged and I went through related issues and PRs , but there is no clear indication of when do you think it would be possible to release that work.

Sometime soon in 2.1 (hopefully) or is that something that really will wait till v3 ?

There currently is no roadmap or release schedule, so there is no way to tell right now.
Consider installing SSP separate from your Symfony 6 application, so our dependencies do not conflict with your apps' dependencies.

Thanks for the quick reply.

Unfortunately for us, decoupling isn't possible because SSP is part of the application. We built a Drupal based IdP for client where Drupal acts as a UI and user self-service portal, and authentication source based on https://github.com/drupalauth/simplesamlphp-module-drupalauth and https://www.drupal.org/project/drupalauth4ssp . Drupal is bootstrapped from inside authn source plugin.

With Drupal 10 requiring Symfony 6 and Drupal 9 EOL this December we are in a very interesting position. Well, we have a bit of time will then.

None of these Drupal modules are compatible with SSP 2.0, so you will have more challenges..
What strikes me is that Drupal completely skipped Symfony 5.4 LTS which is still supported until Nov '25

Thanks for responding to this issue, @tvdijen . I would like to request more technical information, however, on what the motivation for not declaring multiple compatibility with Symfony 5 or 6 in the 2.x version of simplesamlphp is.

Symfony 6 drops support for PHP 7. I can understand that the maintainers of simplesamlphp, wishing to provide ongoing support for the broader community of PHP users, are not yet ready to drop PHP 7 support. However, by using a Composer requirement of "^5.4 || ^6" for symfony components, as is done in the master branch, applications can still require PHP 7 and use simplesamlphp by using Symfony 5.

Is there any other technical reason that the 2.x version cannot declare "^5.4 || ^6" compatibility?

Anecdotally, I can offer that our organization has been using the master branch of this library with a Symfony 6-based application (Drupal 10) since February 2023 without issue.

In the absence of a Symfony 6-compatible release of simplesamlphp our team is considering temporarily forking this library and creating a tag from the master branch so that we can use it with Symfony 6 until simplesamlphp provides its own release that is Symfony-6 compatible. Do you have any opinions on this? We would prefer not to do this, and I assume there are many other Drupal 10 developers who are in the same situation.

Thanks in advance for your input!

I simply couldn't get both versions to work simultaneously due to signature changes. Feel free to contribute.

See #1675 (comment) and following comments for context. It was reverted because the changes were incompatible with PHP 7.4.

The reason to not include Symfony 6 support in 2.0 was because it is only possible to be Symfony 6 compatible when dropping PHP 7 support, it is no problem at all to be compatible with Symfony 5 and 6 at the same time, that is the case now in master.
