Filed one more child 📌 [PHP 8.4] ReflectionMethod costructor deprecated with one argument Needs review

Added https://github.com/phpspec/prophecy/issues/624

beta updates (via commit 2ad2c6b1c4) fixed https://github.com/php-fig/http-factory/commit/2e735aa9fca24c41454faae25...

updated vendor patch as vendor/psr/http-factory/src/UploadedFileFactoryInterface.php is fixed

Tentatively tagging this for 10.3 and 11.0 release highlights. It would be pretty nice to be able to say we're compatible with PHP 8.4 before it's even released, although feels like there might be more breaking changes before it gets to rc, so maybe only really possible for 11.0 rather than 10.3. If there's still outstanding issues or we're not convinced about 8.4 stability, we could change this to 10.4/11.1.

As release schedule updated PHP feature freeze (13 Aug) and first beta at Aug 15 2024

Added to IS

ATM the real blocker to pass tests is "prophecy" as usual, all failed tests are caused by not fixed (nullable types) when mocks are instantiated

btw the commit can be split to new issue https://git.drupalcode.org/project/drupal/-/merge_requests/7783/diffs?co...

Published PHP 8.4_alpha1 image

Composer's dependency fixed https://github.com/jsonrainbow/json-schema/releases/tag/5.3.0

Only 1 failed test left (see #22) https://git.drupalcode.org/issue/drupal-3427903/-/pipelines/226036/test_...

Also there's a lot of deprecations because of prophecy but they could be added to ignored deprecations

That build test failure looks familiar and is something to do with sqlite, 🐛 GenerateThemeTest::testContribStarterkitDevSnapshotWithGitNotInstalled fails on sqlite Needs review shows the same error.

now all tests passed https://git.drupalcode.org/issue/drupal-3427903/-/pipelines/226076/test_...

the commit needs own issue

DDEV HEAD has PHP8.4.0alpha2 now, this should help with resolving the various issues. This will be updated and be in the next DDEV release, but is already available easily via HEAD, even using Homebrew. See https://ddev.readthedocs.io/en/stable/developers/building-contributing/#...

I pushed to CI 8.4alpha3 using patch so in 2 weeks first beta should arive

Ref https://git.drupalcode.org/project/drupalci_environments/-/commit/753d2a...

Guzzle fixed after 📌 Update composer dependencies prior to 11.0.0 Fixed

Moving to target 11.1.0/10.4.0. Some or all of the fixes might still be backportable to the patch branches, but targeting the minors will help us keep track of things as we get closer to the PHP 8.4.0 release.
