feature #17132 [DependencyInjection] Properly ignore invalid reference arguments in collection arguments (ogizanagi)
This PR was merged into the 3.1-dev branch. Discussion ---------- [DependencyInjection] Properly ignore invalid reference arguments in collection arguments | Q | A | ------------- | --- | Bug fix? | no | New feature? | yes | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | - | License | MIT | Doc PR | - With this new feature, the following configuration: ```xml <service id="baz" class="Baz"/> <service id="foo" class="Foo"> <argument type="collection"> <argument type="service" id="bar" on-invalid="ignore" /> <argument type="service" id="baz" /> <argument type="service" id="moo" on-invalid="null" /> </argument> <argument type="service" id="bar" on-invalid="ignore" /> <argument type="service" id="baz" /> <argument type="service" id="moo" on-invalid="null" /> <call method="foo"> <argument type="service" id="bar" on-invalid="ignore" /> </call> <call method="fooCollection"> <argument type="collection"> <argument type="service" id="bar" on-invalid="ignore" /> <argument type="service" id="baz" /> <argument type="service" id="moo" on-invalid="null" /> </argument> </call> </service> ``` will result into the following `Definition`: ```php Definition {#64 ▼ -class: "Foo" // […] -calls: array:1 [▼ 0 => array:2 [▼ 0 => "fooCollection" 1 => array:1 [▼ 0 => array:2 [▼ 0 => Reference {#59 ▼ -id: "baz" -invalidBehavior: 1 } 1 => null ] ] ] ] // […] #arguments: array:4 [▼ 0 => array:2 [▼ 0 => Reference {#63 ▼ -id: "baz" -invalidBehavior: 1 } 1 => null ] 1 => null 2 => Reference {#56 ▼ -id: "baz" -invalidBehavior: 1 } 3 => null ] } ``` Invalid references are ignored instead of replaced by `null` when they are part of a collection argument. If the collection argument is part of a method call and contains an invalid reference, the method call is kept, but the invalid reference removed. The behavior stays the same as before for non-collection arguments. :christmas_tree: Commits ------- cfc4879 [DependencyInjection] Properly ignore invalid reference arguments in collection arguments
