Public bug reported:
Debian started the Symfony 6 transition after Ubuntu's Feature Freeze
started.
Symfony is not only a PHP web framework, but a (large) set of re-usable
libraries.
PHP Standard Recommendations (PSR) are specifications that aim to
standardize programming concepts and techniques in PHP.
The php-psr-* set of packages is used to enforce such specifications
through the interfaces those packages expose to their users.
Symfony 5.x depends on versions 1.x of the php-psr-* stack.
When Ubuntu transitioned to PHP 8 ahead of Debian, back in Jammy, some
of the php-psr-* stack was updated to versions 2.x or 3.x.
Several PHP packages were patched back then to adapt to the new psr
stack, including symfony. However, symfony 5.x is not compatible with
the new PSR stack and the patches left some of the package features
broken.
Moreover, here is the changelog for our current symfony delta:
- d/rules: Disable running phpunit testsuite during build.
- d/p/implement-psr-log-3.patch: Implement psr/log 3
- d/p/implement-psr-link-2.patch: Implement psr/link2 for php8.1
- d/p/implement-psr-container-2.patch: Allow php-psr-container 2.0.2
- d/p/implement-psr-cache-3.patch: Allow php-psr-cache 3.0 for php8.1
- d/t/control: Mark tests flaky for now due to remaining php8.1
inadequacies.
As one can see, despite all the compatibility patches being added, the
fact that the test suite needed to be completely disable should suffice
to show the package is currently not php-psr-* > 1 compatible.
With the Debian transition going on, this seems to be a great
opportunity to fix the situation for noble.
It is also worth noting that, since auto-sync was still enabled for a
while after feature freeze, some new package versions required for the
symfony 6 transition ended up being sync'd already.
Finally, I staged part of the transition in a PPA at
https://launchpad.net/~athos-ribeiro/+archive/ubuntu/symfony6-attempt1/+packages,
where you can find the build logs for symfony at
https://launchpadlibrarian.net/718957076/buildlog_ubuntu-noble-amd64.symfony_6.4.5+dfsg-3~ppa4_BUILDING.txt.gz.
This was needed so we could figure out how to deal with the symfony
circular dependencies so we could get a proper symfony 6 build if/once
this is approved.
Here are the steps we will need to take (not considering potential test
failures):
- Remove the php-symfony-contracts >=3 hard requirement to get a first symfony6
build in the archive
* d/control: remove php-symfony-contracts version requirement to get a first
symfony6 build in the archive.
* d/rules: do not run test suite during build.
- Introduce php-symfony-contracts 3 in the archive
- No-change rebuild symfony with php-symfony-contracts 3
- Revert the symfony changes introduced above, and patch symfony to build with
the latest version of libicu (the patch is already available in the PPA linked
above).
- Check reverse dependencies for pinned symfony versions, to ensure they are
all ready for symfony 6.
For now, we need a FFe to update both
* symfony; and
* php-symfony-contracts.
The upstream changelogs will be attached as comments to this bug.
