Checker Framework 3.11.0

on GitHub

Version 3.11.0, March 1, 2021

User-visible changes:

In a stub file for a class C, you may write a declaration for a method that is inherited by C but not defined by it. Previously, such stub declarations were ignored. For more information, see the manual's documentation of "fake overrides".

Nullness Checker error message key changes:

• known.nonnull => nulltest.redundant
• initialization.static.fields.uninitialized => initialization.static.field.uninitialized, and it is now issued on the field rather than on the class
• new initialization.field.uninitialized is issued on the field instead of initialization.fields.uninitialized on the class, if there is no explicitly-written constructor.

Signature Checker supports two new type qualifiers:

• @CanonicalNameAndBinaryName
• @CanonicalNameOrPrimitiveType

Implementation details:

You can make a variable's default type depend on its name, or a method return type default depend on the method's name. To support this feature, @DefaultFor has new elements names and namesExceptions.

Changes to protected fields in OverrideChecker:

• Removed overriderMeth, overriderTyp, overriddenMeth, overriddenTyp
• Renamed methodReference => isMethodReference
• Renamed overridingType => overriderType
• Renamed overridingReturnType => overriderReturnType

Changes to JavaExpression parsing:

• The signatures of these methods changed; see Javadoc.
  • JavaExpressionParseUtil#parse
  • DependentTypesHelper#standardizeString
• These methods moved:
  • GenericAnnotatedTypeFactory#standardizeAnnotationFromContract => DependentTypesHelper
  • JavaExpressionParseUtil#fromVariableTree => JavaExpression

Changes to JavaExpressionContext:

• New method JavaExpressionContext#buildContextForMethodDeclaration(MethodTree, SourceChecker) replaces all overloads of buildContextForMethodDeclaration.

Parsing a Java expression no longer requires the formal parameters AnnotationProvider provider or boolean allowNonDeterministic. Methods in JavaExpression with simplified signatures include

• fromArrayAccess
• fromNodeFieldAccess
• fromNode
• fromTree
• getParametersOfEnclosingMethod
• getReceiver

CFAbstractStore.insertValue does nothing if passed a nondeterministic expression. Use new method CFAbstractStore.insertValuePermitNondeterministic to map a nondeterministic expression to a value.
