• v0.17.0 Changes

  July 27, 2019

  • Parallelize deserialization of messages received over the network (#821).
    Moving the deserialization out of the I/O loop significantly increases
    🐎 performance. In our benchmark, CAF now handles twice as many messages per
    second.
  • ➕ Add marker to make categories optional on the CLI: Categories are great at
    organizing program options. However, on the CLI they get in the way quickly.
    This change allows developers to prefix category names with ? to make it
    optional on the CLI.
  • 🛠 Fix performance of thread-safe actor clock (#849). This clock type is used
    whenever sending requests, delayed messages, receive timeouts etc. CAF can
    🖐 handle about 10x more timeouts per second after the patch.

  • 😌 Relax ini syntax for maps by making = for defining maps and , for
    separating key-value pairs optional. For example, this change allows to
    rewrite an entry like this:

    logger = { console-verbosity='trace', console='colored'}

  to a slightly less noisy version such as this:

  logger { console-verbosity='trace'console='colored'}
  

  • 👍 Allow apps to always use the caf::logger, whether or not CAF was compiled
    🌲 with logging enabled.
  • 🛠 Fix over- and underflow checks in number parser (#852).
  • 🛠 Fix multicast address detection in caf::ipv4_address.cpp (#853).
  • 🛠 Fix disconnect issue / WSAGetLastError usage on Windows (#846).
  • 🛠 Fix --config-file option (#841).
  • 🛠 Fix parsing of CLI arguments for strings and atom values.
  • ➕ Add conversion from nullptr to intrusive and COW pointer types.
  • 👍 Streamline direct node-to-node communication and support multiple app
    identifiers.
  • Reimplement binary_serializer and binary_deserializer without STL-style
    🐎 stream buffers for better performance.
  • 👌 Support move-only behavior functions.
  • 👍 Allow users to omit global in config files.
  • 👍 Allow IPO on GCC/Clang (#824).

• v0.16.5 Changes

  November 11, 2019

  ➕ Added

  • 👌 Support for OpenBSD.

• v0.16.4 Changes

  November 11, 2019

  🛠 Fixed

  • 📜 Backport parser fixes from the CAF 0.17 series.
  • ⚠ Silence several compiler warnings on GCC and Clang.

• v0.16.3 Changes

  December 27, 2018

  ➕ Added

  • The new class cow_tuple provides an std::tuple-like interface for a heap-allocated, copy-on-write tuple.
  • Missing overloads for dictionary.
  • The new to_lowercase function for atoms allows convenient conversion without having to convert between strings and atoms.

  🔄 Changed

  • 🖨 Printing timestamps now consistently uses ISO 8601 format.
  • The logger now uses a bounded queue. This change in behavior will cause the application to slow down when logging faster than the logger can do I/O, but the queue can no longer grow indefinitely.
  • Actors now always try to dequeue from the high-priority queue first.

  🛠 Fixed

  • 🏗 Solved linker errors related to socket_guard in some builds.
  • 🛠 Fix the logger output for class names.
  • Deserializing into non-empty containers appended to the content instead of overriding it. The new implementation properly clears the container before filling it.
  • The split function from the string algorithms header now works as the documentation states.
  • ⚠ Silence several compiler warnings on GCC and Clang.

• v0.16.2 Changes

  November 03, 2018

  🛠 Fixed

  • 🚀 The copy-on-write pointer used by message failed to release memory in some cases. The resulting memory leak is now fixed.

• v0.16.1 Changes

  October 31, 2018

  ➕ Added

  • ➕ Adding additional flags for the compiler when using the configure script is now easier thanks to the --extra-flags= option.
  • 👍 The actor clock now supports non-overriding timeouts.
  • The new intrusive_cow_ptr is a smart pointer for copy-on-write access.

  🔄 Changed

  • 👌 Improve noexcept-correctness of variant.
  • CAF threads now have recognizable names in a debugger.
  • The middleman now passes CLOEXEC on socket/accept/pipe calls.
  • 🌲 Users can now set the log verbosity for file and console output separately.

  🛠 Fixed

  • A dictionary now properly treats C-strings as strings when using emplace.
  • Eliminate a potential deadlock in the thread-safe actor clock.
  • ➕ Added various missing includes and forward declarations.
