WebSocket++ v0.7.0 Release Notes

Release Date: 2016-02-22 // about 8 years ago
    • MINOR BREAKING SOCKET POLICY CHANGE : Asio transport socket policy method cancel_socket will now return lib::asio::error_code instead of void. Custom Asio transport socket policies will need to be updated accordingly. This does not affect anyone using the bundled socket policies.
    • 🔋 Feature : Basic support for the permessage-deflate extension. #344
    • 🔋 Feature : Allow accessing the local endpoint when using the Asio transport. This allows inspection of the address and port in cases where they are chosen by the operating system rather than the user. Thank you Andreas Weis and Muzahid Hussain for reporting and related code. #458
    • 🔋 Feature : Add support for subprotocols in Hybi00. Thank you Lukas Obermann for reporting and a patch. #518
    • 👌 Improvement : Better automatic std::chrono feature detection for Visual Studio
    • 👌 Improvement : Major refactoring to bundled CMake build system. CMake can now be used to build all of the examples and the test suite. Thank you Thijs Wenker for a significant portion of this code. #378, #435, #449
    • 👌 Improvement : In build environments where lib::error_code and lib::asio::error_code match (such as using boost::asio with boost::system_error or standalone asio with std::system_error, transport errors are passed through natively rather than being reported as a translated pass_through error type.
    • 👌 Improvement : Add a get_transport_error method to Asio transport connections to allow retrieving a machine readable native transport error.
    • 👌 Improvement : Add connection::get_response, connection::get_response_code, and connection::get_response_msg methods to allow accessing additional information about the HTTP responses that WebSocket++ sends. #465 Thank youFlow86 for reporting.
    • 👌 Improvement : Removes use of empty strings ("") in favor of string::clear() and string::empty(). This avoids generating unnecessary temporary objects. #468 Thank you Vladislav Yaroslavlev for reporting and a patch.
    • 📚 Documentation : Adds an example demonstrating the use of external io_service
    • 📚 Documentation : Adds a simple echo_client example.
    • 📚 Documentation : Begins migration of the web based user manual into Doxygen.
    • 🐛 Bug : Fix memory leak when init_asio produces an error. #454 Thank you Mark Grimes for reporting and fixing.
    • 🐛 Bug : Fix crash when processing a specially crafted HTTP header. Thank you Eli Fidler for reporting, test cases, and a patch. #456
    • 🐛 Bug : Fix an issue where standalone Asio builds that use TLS would not compile due to lingering boost code. #448 Thank you mjsp for reporting
    • 🐛 Bug : Fix an issue where canceling a socket could throw an exception on some older Windows XP platforms. It now prints an appropriate set of log messages instead. Thank you Thijs Wenker for reporting and researching solutions. #460
    • 🐛 Bug : Fix an issue where deferred HTTP connections that start sending a very long response before their HTTP handler ends would result in a second set of HTTP headers being injected into the output. Thank you Kevin Smith for reporting and providing test case details. #443
    • 🐛 Bug : Fix an issue where the wrong type of strand was being created. Thank you Bastien Brunnenstein for reporting and a patch. #462
    • 🐛 Bug : Fix an issue where TLS includes were broken for Asio Standalone builds. Thank you giachi and Bastien Brunnenstein for reporting. #491
    • 🐛 Bug : Remove the use of cached read and write handlers in the Asio transport. This feature caused memory leaks when the io_service the connection was running on was abruptly stopped. There isn't a clean and safe way of using this optimization without global state and the associated locks. The locks perform worse. Thank you Xavier Gibert for reporting, test cases, and code. Fixes #490.
    • 🐛 Bug : Fix a heap buffer overflow when checking very short URIs. Thank you Xavier Gibert for reporting and a patch #524
    • Compatibility : Fixes a number of build & config issues on Visual Studio 2015
    • Compatibility : Removes non-standards compliant masking behavior. #395, #469
    • Compatibility : Replace deprecated use of auto_ptr on systems where unique_ptr is available.
