Maybe we could split the AutowirePass in two parts: first, we would register all the missing services; in a second time, we would do the real autowiring. That would fix this issue but probably other edge cases would still be there. Sounds like a complicated issue. Another idea: store the types used previously and check that new services registered don't implement them. |

…andidates (nicolas-grekas) This PR was merged into the 2.8 branch. Discussion ---------- [DI] Don't use auto-registered services to populate type-candidates | Q | A | ------------- | --- | Branch? | 2.8 | Bug fix? | yes | New feature? | no | BC breaks? | no (every bug fix is a bc break, isn't it?) | Deprecations? | no | Tests pass? | yes | Fixed tickets | #22162, ~~#21658~~ | License | MIT | Doc PR | symfony/symfony-docs#... <!--highly recommended for new features--> Alternative to #22170 and ~~#21665~~. The core issue fixed here is that auto-registered services should *not* be used as type-candidates. The culprit is this line: `$this->populateAvailableType($argumentId, $argumentDefinition);` Doing so creates a series of wtf-issues (the linked ones), with no simple fixes (the linked PRs are just dealing with the simplest cases, but the real fix would require a reboot of autowiring for every newly discovered types.) The other changes accommodate for the removal of the population of the `types` property, and fix a few other issues found along the way: - variadic constructors - empty strings injection - tail args removal when they match the existing defaults Commits ------- 992c677 [DI] Don't use auto-registered services to populate type-candidates

That's a failing test case, showing that autowiring collisions detection sometimes relies on ordering, which should not be the case.
