  • Fix potential order of destruction problem in SessionTimeoutService.
  • Fix bool conversion compiler error in RcfSession::hasDefaultServerStub() (reported on gcc 4.6.3) .
  • Accumulate multiple ByteBuffer's in SSPI filter, to prevent potential fragmentation of network send operations.
  • ThreadPool refactored, with simpler constructors and get \/ set methods.
  • Classes renamed: I_Endpoint to Endpoint, I_ServerTransport to ServerTransport, I_ClientTransport to ClientTransport, I_NetworkSession to NetworkSession, I_RemoteAddress to RemoteAddress.
  • Removed NamedPipeEndpoint class. Code using NamedPipeEndpoint should use Win32NamedPipeEndpoint or UnixLocalEndpoint instead.
  • Refactoring and simplifications to SSL functionality:
    • Added RCF::setSslImplementation(), RcfServer::setSslImplementation() and ClientStub::setSslImplementation() , to configure whether RCF uses Schannel or OpenSSL.
    • Renamed setSslCertificate() to setCertificate(), and setSslCaCertificate() to setCaCertificate().
    • Merged certificate validation callback signature, from std::function<bool(OpenSslEncryptionFilter &)> and std::function<bool(SspiFilter &)> , to std::function<bool(I_Certificate *)>.
    • Merged setSchannelCertificateValidationCb() and setOpenSslCertificateValidationCb() , to setCertificateValidationCallback().
    • Renamed setSchannelDefaultCertificateValidation() to setEnableSchannelCertificateValidation().
    • Added Win32Certificate::getCertificateName(), Win32Certificate::getIssuerName(), X509Certificate::getCertificateName(), and X509Certificate::getIssuerName() functions.
    • Referencing arbitrary Windows stores from PfxCertificate::addToStore() and StoreCertificate::StoreCertificate() , using the Win32CertificateLocation and Win32CertificateStore enums.
    • Added StoreCertificateIterator class, for iterating through certificates in a Windows store.

RCF 2.0.0.2679 - 2013-03-27

  • Add dummy parameters to RCF::init() and RCF::RcfInitDeinit::RcfInitDeinit(), to trap compiler define mismatches when building RCF as a DLL.
  • Server throws an exception immediately, if a client specifies a ping-back interval that is less than the minimum ping-back interval of the server.

RCF 2.0.0.2678 - 2013-03-07

  • Fix compatibility with Boost 1.53.0, by removing usages of boost::shared_static_cast<>.
  • Increase the maximum number of RCF methods in a RCF interface, from 100 to 200. If you need more than 100 methods, define RCF_MAX_METHOD_COUNT=200 in your build.
  • zlib and OpenSSL libraries are now loaded dynamically at runtime, rather than linked. This means that if you are building RCF with RCF_USE_ZLIB or RCF_USE_OPENSSL, you no longer need to link to zlib and OpenSSL. RCF will load the zlib and OpenSSL libraries at runtime, on the first execution of any compression code, or OpenSSL-based encryption code.
  • Changed Visual Studio demo solution, to build and use a RCF DLL.
  • Changed cmake demo projects, to link against pthread and dl on non-Windows platforms.

  • Add I_ServerTransport::getInitialNumberOfCOnnections() / I_ServerTransport::setInitialNumberOfCOnnections() to get and set the initial number of listening connections that are created when a server transport starts. Default value is 1.
