Change Log for sockpp

Version 0.8.2 - (2023-12-05)

  • #89 Fixed generator expression for older CMake
  • #91 Fixed uniform_int_distribution<> in UNIX socket example

Version 0.8.1

Released: 2023-01-30

  • Cherry picked most of the non-TLS commits in PR #17
    • Connector timeouts
    • Stateless reads & writes for streaming sockets w/ functions returning ioresult
    • Some small bug fixes
    • No shutdown on invalid sockets
  • #38 Made system libs public for static builds to fix Windows
  • #73 Clone a datagram (UDP) socket
  • #74 Added <sys/time.h> to properly get timeval in *nix builds.
  • #56 handling unix paths with maximum length (no NUL term)
  • Fixed outstanding build warnings on Windows when using MSVC

Version 0.8.0

Released: 2023-01-17

  • [Breaking] Library initializer now uses a static singleton created via socket_initializer::initialize() call, which can be called repeatedly with no ill effect. Also added global socketpp::initialize() function as shortcut.
  • Improvements to CMake to better follow modern standards.
    • CMake required version bumped up to 3.12
    • Generating CMake files for downstream projects (config, target, version)
    • Windows builds default to shared DLL, not static library
    • Lots of cleanup

Version 0.7.1

Released: 2022-01-24

  • [Experimental] SocketCAN, CAN bus support on Linux
  • #37 socket::get_option() not returning length on Windows
  • #39 Using SSIZE_T for ssize_t in Windows
  • #53 Add Conan support
  • #55 Fix Android strerror
  • #60 Add missing move constructor for connector template.
  • Now acceptor::open() uses the SO_REUSEPORT option instead of SO_REUSEADDR on non-Windows systems. Also made reuse optional.

Version 0.7

  • Base socket class
    • shutdown() added
    • create() added
    • bind() moved into base socket (from acceptor)
  • Unix-domain socket pairs (stream and datagram)
  • Non-blocking I/O
  • Scatter/Gather I/O
  • stream_socket cloning.
  • Set and get socket options using template types.
  • stream_socket::read_n() and write_n() now properly handle EINTR return.
  • to_timeval() can convert from any std::chrono::duration type.
  • socket::close() and shutdown() check for errors, set last error, and return a bool.
  • tcpechomt.cpp: Example of a client sharing a socket between read and write threads - using clone().
  • Windows enhancements:
    • Implemented socket timeouts on Windows
    • Fixed bug in Windows socket cloning.
    • Fixed bug in Windows socket::last_error_string.
    • Unit tests working on Windows
  • More unit tests

Version 0.6

  • UDP support
    • The base datagram_socket added to the Windows build
    • The datagram_socket cleaned up for proper parameter and return types.
    • New datagram_socket_tmpl template class for defining UDP sockets for the different address families.
    • New datagram classes for IPv4 (udp_socket), IPv6 (udp6_socket), and Unix-domain (unix_dgram_socket)
  • Windows support
    • Windows support was broken in release v0.5. It is now fixed, and includes the UDP features.
  • Proper move semantics for stream sockets and connectors.
  • Separate tcp socket header files for each address family (tcp_socket.h, tcp6_socket.h, etc).
  • Proper implementation of Unix-domain streaming socket.
  • CMake auto-generates a version header file, version.h
  • CI dropped tests for gcc-4.9, and added support for clang-7 and 8.

Version 0.5

  • (Breaking change) Updated the hierarchy of network address classes, now derived from a common base class.
    • Removed sock_address_ref class. Now a C++ reference to sock_address will replace it (i.e. sock_address&).
    • sock_address is now an abstract base class.
    • All the network address classes now derive from sock_address
    • Consolidates a number of overloaded functions that took different forms of addresses to just take a const sock_address&
    • Adds a new sock_address_any class that can contain any address, and is used by base classes that need a generic address.
  • The acceptor and connector classes are still concrete, generic classes, but now a template derives from each of them to specialize.
  • The connector and acceptor classes for each address family (tcp_connector, tcp_acceptor, tcp6_connector, etc) are now typedef'ed to template specializations.
  • The acceptor::bind() and acceptor::listen() methods are now public.
  • CMake build now honors the CMAKE_BUILD_TYPE flag.

Version 0.4

The work in this branch is proceeding to add support for IPv6 and refactor the class hierarchies to better support the different address families without so much redundant code.

  • IPv6 support: inet6_address, tcp6_acceptor, tcp_connector, etc.
  • (Breaking change) The sock_address class is now contains storage for any type of address and follows copy semantics. Previously it was a non-owning reference class. That reference class now exists as sock_addresss_ref.
  • Generic base classses are being re-implemented to use sock_address and sock_address_ref as generic addresses.
  • (Breaking change) In the socket class(es) the bool address(address&) and bool peer_address(addr&) forms of getting the socket addresses have been removed in favor of the ones that simply return the address. Added get_option() and set_option() methods to the base socketclass.
  • The GNU Make build system (Makefile) was deprecated and removed.

Version 0.3

  • Socket class hierarcy now splits out for streaming and datagram sockets.
  • Support for UNIX-domain sockets.
  • New modern CMake build system.
  • GNU Make system marked for deprecation.

Version 0.2

  • Initial working version for IPv4.
  • API using boolean return values for pass/fail functions instead of syscall-style integers.
