Unable to parse generic types with generic type arguments #728
Comments
|
It looks like we are throwing the exception trying to parse generic types with generic types: I will work on fixing our parser to support this. The only workaround I can think of is to remove the methods that are trying to use this type: |

@jpobst Thank you very much for the fast analysis! Can you already provide a rough estimate when this issue is going to be fixed? |

Fixes: #728 Context: https://xamarin.github.io/bugzilla-archives/12/12468/bug.html#c1 In order to avoid CS0234 errors, we always write non-intrinsic types prefixed with `global::`. For example, instead of System.Collections.Generic.List<Java.Lang.Object> `generator` emits global::System.Collections.Generic.List<global::Java.Lang.Object> To do this, we have to parse a type into its component types so we can add `global::` to each part. However, our parsing algorithm struggles with generic types with multiple type arguments. Thus, this: System.Collections.Generic.IDictionary<System.Collections.Generic.IList<string>, Kotlin.Pair> loses the second template parameter, becoming: global::System.Collections.Generic.IDictionary<global::System.Collections.Generic.IList<string>> while this: System.Collections.Generic.IDictionary<System.Collections.Generic.IList<string>, System.Collections.Generic.IList<Kotlin.Pair>> throws an `ArgumentOutOfRangeException`, which is the cause of #728. Fix the `ArgumentOutOfRangeException` by introducing a new recursive parser that better understands generic types.
