Serialization version 3: update method serialization to exclude type use annotations and type arguments (uber#735) This PR updates serialization to version `3` and burns version `2`. Changes in serialization version 3: - Type arguments and Type use annotations are excluded from the serialized method signatures. --- Additional context: This PR updates method serialization to ensure only relevant information in a method signature is serialized. Previous to this PR, method signatures serialization was relying on calling `.toString()` method, but if a parameter contains an annotation of type `@Target({TYPE_USE})` the annotation will exist in the `.toSting()` output which is not part of a method signature. This PR updates serialization to ensure exact method signature as expected is serialized. Suggested change suggested changes ternary operator as a method argument Docs: `-XepExcludedPaths` was added in 2.1.3, not 2.13 (uber#744) Add command line option to skip specific library models. (uber#741) This PR adds the CLI option `-XepOpt:NullAway:IgnoreLibraryModelsFor` which takes a list of methods, given as fully qualified class name + method simple name (i.e. independent of argument types). Methods matching this list will be skipped when loading library models (from any implementation of the `LibraryModels`'s `@AutoService` as well as our included models). This can be used in a per-compilation target basis to disable NullAway's library models for ease of upgrading to new versions with stricter modeling of common JDK or third-party APIs. We considered a few alternative approaches here, but decided against: - Simply using another instance of `LibraryModels` to "invert" the models given by NullAway's default library models: This would have required no code changes, but doesn't work in all cases. If NullAway's default models make the return of method `foo()` `@Nullable`, for example, then a new model that makes the return `@NonNull` will break `@Nullable` overrides of `foo()`. In general, we want to go back to "optimistic assumptions" rather than just replace the library model. - We could have a list of methods in the `LibraryModels` for which to ignore previous models, and have those override any models on those methods coming from a different `LibraryModels` implementation. But, from the point of view of the user configuring NullAway, this is complex: they need to have an instance of custom library models in their build, and changing java plugin classpath deps on a per-target basis is more complex than changing CLI arguments (e.g. due to JVM re-use by the build system). - We could provide more specific disabling of library models (e.g. a specific method signature or removing only one particular kind of model from a method, such as keeping the model on the return value, but removing it from an argument, or removing a null-implies-false model or similar). We could revisit this in the future, but supporting this would make the syntax of the CLI values a lot more complex. For now, we believe just turning off all models for a given method is a sufficient degree of granularity. - Per-package/per-class/regex based ignore specs: See above. Avoiding complexity until we need it. Note: If and when this lands, it needs a Wiki documentation update! --------- Co-authored-by: Manu Sridharan <[email protected]>
