Change Log

All notable changes to the Pony compiler and standard library will be documented in this file. This project adheres to Semantic Versioning and Keep a CHANGELOG.

Changed

  • Interfaces are invariant if they are structurally equivalent.
  • Improved type checking with configuration management.
  • Improved realloc behaviour after heap_alloc_large.
  • Set-based upper bounds for generic constraints.
  • Moved the position of a default capability in a type specification.
  • Replaced '&' with 'addressof' for taking address in FFI calls.
  • @jemc: use half-open ranges for String operations.
  • Improved TCPConnection with a dynamically size of buffers
  • Drop dynamic LTO detection in the build system.
  • Parameterized Array.find and Array.rfind with a comparator.
  • this-> adapted types check match on the upper bounds.
  • Renamed identityof to digestof.
  • Renamed net/Buffer to net/ReadBuffer
  • Print compiler error and info messages to stderr instead of stdout.
  • Hashmap.concat now returns this rather than None

[0.2.1] - 2015-10-06

Fixed

  • Check shallow marking in heap_ismarked.

[0.2.0] - 2015-10-05

Added

  • Platform indicators for LP64, LLP64, ILP32.
  • Compile and link with LTO.
  • Use Pointer[None] for void* in FFI.
  • Root authority capability in Env.
  • Fine grained capabilities for files and directories.
  • Use Capsicum on FreeBSD.
  • Apply can be sugared with type arguments.
  • Search pony_packages directories for use commands.
  • Buffer peek functions (@jemc)
  • collections/Ring
  • Promises package

Changed

  • Renamed some builtin types.
  • abs() now returns an unsigned integer.
  • Improved memory allocation speed.
  • Reduced memory pressure.
  • Scheduler steals when only the CD is on a scheduler thread queue.
  • use commands searches ../pony_packages recursively similar to Node.js
  • Readline uses a Promise to handle async reponses.

Fixed

  • Handle internal pointers and recursion.
  • Allow recursing through non-pony alloc'd memory in GC.
  • Set an LLVM triple with no version stamp to prevent XCode 7 link warnings.
  • use "path:" adds link paths only for the current build.

[0.1.7] - 2015-06-18

Added

  • Pass Pony function pointers to C FFI.

Changed

  • The pony runtime now uses the same option parser as ponyc. A pony program exits if bad runtime args are provided.
  • Output directory now created if it doesn't already exist.
  • Improvements to automatic documentation generator.
  • Union type for String.compare result.

Fixed

  • Viewpoint adaptation with a type expression on the left-hand side.

[0.1.6] - 2015-06-15

Added

  • Automatic documentation generator in the compiler.
  • FreeBSD 10.1 support, thanks to Ben Laurie.
  • Allow method calls on union types when the signatures are compatible.
  • Subtyping of polymorphic methods.
  • Primitive _init and _final for C library initialisation and shutdown.
  • collections.Flags
  • lambda sugar.

Changed

  • Separated the FFI '&' operator from the identityof operator.
  • Operators on Set and Map are now persistent.
  • use "file:..." becomes use "package:..."
  • Allow "s at the end of triple-quoted strings.
  • Allow behaviours and functions to be subtypes of each other.

Fixed

  • ANSI stripping on zero length writes to stdout/stderr.
  • More OS X 10.8 compatibility.
  • SSL multithreading support.
  • Nested tuple code generation.
  • Only finalise blocked actors when detecting quiescence.
  • URL parse error.

[0.1.5] - 2015-05-15

Fixed

  • OS X 10.8 compatibility.

[0.1.4] - 2015-05-14

Changed

  • When using a package without a package identifier (eg. use "foo" as opposed to use f = "foo"), a Main type in the package will not be imported. This allows all packages to include unit tests that are run from their included Main actor without causing name conflicts.
  • The for sugar now wraps the next() call in a try expression that does a continue if an error is raised.

Added

  • ANSI terminal handling on all platforms, including Windows.
  • The lexer now allows underscore characters in numeric literals. This allows long numeric literals to be broken up for human readability.
  • "Did you mean?" support when the compiler doesn't recognise a name but something similar is in scope.
  • Garbage collection and cycle detection parameters can now be set from the command line.
  • Added a FileStream wrapper to the file package.

Fixed

  • Check whether parameters to behaviours, actor constructors and isolated constructors are sendable after flattening, to allow sendable type parameters to be used as parameters.
  • Eliminate spurious "control expression" errors when another compile error has occurred.
  • Handle circular package dependencies.
  • Fixed ponyc options issue related to named long options with no arguments
  • Cycle detector view_t structures are now reference counted.
