Release Notes

dart-lang/native (ffigen)

v22.0.0

Compare Source

• Breaking change: Major overhaul of Dart config API:
  • Replace various callback based config elements with a Visitor pattern.
    • rename and renameMember replaced with .name setters on AST nodes.
    • include and includeMember replaced with .isIncluded on AST nodes.
    • Functions/Globals.includeSymbolAddress replaced with
      .exposeSymbolAddress on AST nodes.
    • Functions.includeTypedef replaced with .generateTypedefs on
      Func AST node.
    • Structs.packingOverride replaced with Struct.pack.
    • Enums.style and .silenceWarning moved to EnumClass AST node.
    • Functions.isLeaf and .recordUse moved to Func AST node.
    • Structs/Unions.dependencies moved to Struct/Union AST nodes.
    • Interfaces/Protocols.module moved to ObjCInterface/ObjCProtocol AST
      nodes.
    • Interfaces/Protocols.includeTransitive removed (always false).
    • Categories.includeTransitive replaced with
      ObjCInterface.includeCategories.
    • Typedefs.includeUnused consolidated into Typealias.isIncluded using
      TypealiasInclude enum (never, ifUsed, always).
  • Consolidate imported fields and importedTypesByUsr into
    FfiGenerator.importType, switching it to a callback pattern
  • Add importFromSymbolFile and importFromSymbolFiles utils, which load
    symbol YAML files, and return functions that can be passed directly to
    FfiGenerator.importType.
  • Replace Output.dartFile with DartOutput, to prepare for upcoming
    multi-file output format.
  • Deleted many now empty sub-config classes
  • Rename Headers to Input
  • Remove libraryImports, which was dead code
  • Remove useSupportedTypedefs, treating it as always true
  • Make preamble non-null
  • Make generate function async
• Fix a bug in handling of
  small structs in ObjC on mac/iOS x64.
• Fix a bug in the way that
  ObjC category methods returning instancetype are filtered.
• Minor Objective-C code generator and function type signature fixes.
• Bump package:code_assets dependency to ^2.0.0.

v21.0.0

• Propagate @Deprecated annotations from C/ObjC headers into generated Dart
  bindings. Deprecation messages from __attribute__((deprecated("msg"))) and
  API_DEPRECATED("msg", ...) are included in the annotation.
• Breaking change: Remove deprecated useDartHandle field from
  FfiGenerator.
• Breaking change: Remove unused includeSymbolAddress field from
  Categories, Interfaces, and Protocols.
• Breaking change: Remove deprecated wrapperName field from
  NativeExternalBindings.
• Breaking change: Certain synthetic USRs have been modified to ensure they
  cannot collide with real USRs. It's very unlikely that any user facing USRs
  are affected.
• Enum struct members now have setters.
• Breaking change: Dart const values will be generated for global variables
  marked const in C (e.g. static const int) instead of symbol lookups. This
  supports integers, doubles, and string literals. Including the variable name
  in the globals -> symbol-address configuration will still generate symbol
  lookups.
• Fix a bug where block
  helpers were occasionally given unexpected names. Technically a breaking
  change because if you were affected by the bug, the block helper's name will
  change to something more sensible.
• Breaking change: Deleted the config option Output.sort. Sorting is now
  always enabled.
• Fix(#​2877)
  such that ObjCObject isA now accepts a nullable ObjCObject? and returns
  false when called with null, aligning its behavior with Dart’s is
  operator.
• Use xcrun for resolving macOS SDK paths, enabling support for non-standard
  Xcode installations. #​3134
• Add allocate constructor for native C structs:
  $allocate(Allocator $allocator, {required ...})
• Fix a bug where ObjC
  classes with SWIFT_UNAVAILABLE annotated init/new methods were
  generating runtime-crashing no-arg constructors.
• Fix a bug where methods marked with __attribute__((unavailable)) were
  incorrectly included in bindings when no platform version info was configured.
• Add some more lint ignores to the generated bindings.
• Fix a bug where the config option Protocols.includeTransitive was not
  working correctly.
• Add compile time version checks to verify consistency of package:objective_c's
  versions vs FFIgen's generated code.
• Fix a bug where ObjC
  bindings may not auto-load their dylib in some cases.
• Fix memory leaks, deadlocks, and crashes that can happen in callbacks, if the
  target isolate is shut down.
• Bump package:meta dependency to ^1.19.0 and stop generating
  experimental_member_use lint ignore in generated bindings when
  @RecordUse() is used.
• Support versions 3.x of package:package_config.
• Fix a bug where comments containing carriage return (\r) characters were not
  properly split, causing comment text to spill out of Dart doc comments.
