Version 4.xx

[4.0.56] - 2025-05-19

This is a Quality Assured Release.

Note: the Ubuntu 18.04 binary distribution package is deprecated

We are sunsetting the distribution of Ubuntu 18.04 packages with this release. With the next release, we will provide Ubuntu 24.04 binary distribution packages instead.

Note: we will change our versioning scheme to semantic versioning

Please read the full notice in the Semantic Versioning page in the documentation.

Fixed

• Three static methods which are part of the C++ (Hourglass) API implementation and passed as callbacks to the C-API, did not use the correct calling convention if the default calling convention wasn’t __cdecl on Windows. This has been remedied.

• SilKitDemoSimStepAsync did not work as intended, due to the predicate lambda capturing by-value instead of by-reference.

• During hop-on of another participant, participants will send the current simulation step instead of the next simulation step, if they are inside of their simulation step.

Changed

• The participant configuration TcpNoDelay now defaults to true. Please note, that this has performance implications. On Linux platforms this improves throughput, and latency in particular when used in combination with TcpQuickAck: true.

• Updated third party libraries - asio to 1.30.2 - fmt to 11.1.4 - spdlog to 1.15.2

• Add the myst_parser extension to documentation build, which allows using Markdown for documentation pages

• Automatically ‘upgrade’ the Doxyfile using doxygen -u, which avoids warnings when with different doxygen versions across distibutions

• CAN XL: Update documentation, tests, and the demo to (better) reflect that we support it

Added

• The documentation now contains a page that explains the upcoming new versioning scheme.

• Experimental ‘other-simulation-steps-completed’ API

[4.0.55] - 2025-01-31

This is a Quality Assured Release.

Changed

• Important SilKit_LinDataLengthUnknown in the C header Lin.h used to be a const global, which could cause linker issues if the header file is used in multiple translation units in the same binary.

  It has been turned into a #define, like all the other constants in the C header files.

  The symbol was not present in the dynamic symbol table of the SilKit.dll / .so, so this change does not break the ABI of the shared libraries.

• Aligned C API error return codes SilKit_ReturnCode_<ERRORTYPE> and SIL Kit specific exceptions. All exceptions are now forwarded through the hourglass and thrown in the C++ API. For users of the C API, a more detailed error handling is possible with the extended error return codes.

  Before, all execptions ended up as SilKitError on the user side.

• Overhaul of SIL Kit demos

  • Restructured into categories communication, api and tools

  • Communication demos: Can, Ethernet, Lin, Flexray, PubSub and Rpc demos

    • These demos are split into one participant per executable

    • Basic SIL Kit features are implemented in a base class used by the demos

    • No command line arguments needed for basic execution (with time synchronization and coordinated start)

    • Useful command line arguments are provided for all demos (e.g. rename the participant or network, logging, execution modes)

    • The old --async mode of the demos now is accessible by --async --autonomous (or short form -aA)

Added

• New demos for basic API usage

  • SimpleCan

  • Orchestration demos

• Demos: Sample participant configurations

Fixed

• Registry: Block all attempts to connect with an already present participant name, not just the first.

• CMake: When demos are installed into the bin directory under the installation prefix, their RPATH will be set such that they are able to find the libSilKit[d].so. This is the same RPATH value as the utility executables.

• System Monitor: Show all participants, not just the ones that joined during the monitors execution.

[4.0.54] - 2024-11-11

Added

• Override the labels of DataPublisher, DataSubscriber, RpcClient, and RpcServer instances through the participant configuration, extending the already possible override of the topic / function name.

Changed

• Changed log messages for controller and participant creation, message tracing, system state tracker and time sync service

• Revised the documentation (demos, troubleshooting, doxygen output, file structure)

• Improved platform/compiler/architecture detection

Fixed

• Failure to configure and package cross-builds to QNX on Windows

[4.0.53] - 2024-10-11

Changed

• Harmonized user interface of commandline utilities Registry, Monitor, and SystemController.

  All utilities listen to OS signals to detect termination request.

  • Old: Monitor and Registry wait for the user to press [Enter] to shutdown.

  • New: Monitor and Registry can be requested to shutdown via [Ctrl]-[C]. Registry option -s, --use-signal-handler is deprecated.

  All utilities no longer require user interaction.

  • Old: Registry, Monitor and System Controller prompt the user by default to press [Enter] to end process after shutdown.

  • New: All utilities terminate without prompting for user input. SystemController option -ni, --non-interactive is deprecated.

• The Logger now adds the participant’s name (as a normalized string) to the user-defined LogName for file sinks.

• Implemented the union (de-)serialization stubs in the silkit/util/serdes headers.

Fixed

• If using the SimStepHandlerAsync, the log message that reports the end of the simulation step is now printed after the call to CompleteSimulationStep.

• Fixed an issue with the NetSim API that caused an exception when used with log level trace.

[4.0.52] - 2024-09-02

Fixed

• Fixed crash in sil-kit-registry utility that happened when the dashboard is enabled, but not actually available.

Added

• Message aggregation for simulations with time synchronization. Accessible via the experimental section in the Participant Configuration (Experimental | TimeSynchronization | EnableMessageAggregation).

[4.0.51] - 2024-07-18

Added

• Couple the virtual time to the wall clock. An animation factor can be configured that describes how fast the simulation is allowed to run relative to the local wall clock. Accessible via a new experimental section in the Participant Configuration (Experimental | TimeSynchronization | AnimationFactor).

• Event flow documentation for the Network Simulation API.

• Registry (Dashboard): Automatically use bulk-endpoint if it is available

• Configuration option for structured logging in JSON format

[4.0.50] - 2024-05-15

This is a Quality Assured Release.

Fixed

• Fixed crash in sil-kit-system-controller utility.

• Fixed source directory contents in .zip release archives.

[4.0.49] - 2024-05-08

Changed

• SystemController utility: Listens for OS signals to end simulation: Press [Ctrl]-[C] (SigInt) instead of [Enter] to end simulation. Better reports about the current system state in case of Error.

Fixed

• Valid state transition from Aborting to Shutdown no longer emits a warning message.

Added

• Participant Configuration: Support include semantics in participant configuration files/strings.

• Network Simulation: Experimental API for custom simulation of CAN, LIN, Ethernet and FlexRay networks.

[4.0.48] - 2024-04-15

Changed

• We now use a linker script to limit the exported symbol visibility to the public C API and some legacy C++ symbols.

• The --enable-dashboard CLI parameter for the registry is now a no-op. It is now activated when using --dashboard-uri or via the registry configuration.

Fixed

• Fix MinGW build.

• LIN Demo: Removed duplicate call to StartLifecyle when run as the LIN slave

[4.0.46] - 2024-02-27

Fixed

• Added the *.manifest files to the source distribution. Building from the SilKit-Source directory in the distributed .zip files was broken.

• Update yaml-cpp to version 0.8.0 to fix linker errors caused by a missing symbol.

• The system controller utility now logs parts of the command line output using the logger object of the participant.

Added

• Added a --log option to the system controller utility which cannot be used together with the --configuration option. It provides a shortcut to set the log level of the utility.

• Utilities: prepare the registry for handling multiple simulations

• Added a licensecheck to prevent source files without a license header

[4.0.45] - 2024-02-06

Fixed

• Registry failed to start correctly, if the dashboard is enabled, but the registry is letting the system determine the listening port, e.g., when using a URI like silkit://localhost:0.

Changed

• Add links to API sections in the documentation overview

Added

• RPC usage example with lifecycle

• Windows: Utilities and demos are now compiled with a manifest that sets the active codepage to UTF-8. The required commands to change the output codepage of the Windows console in cmd or PowerShell are documented in a new FAQ entry.

[4.0.44] - 2024-01-22

Fixed

• Changing the TCP send and receive buffer size failed on Windows

[4.0.40] - 2023-11-27

Added

• Allow configuration of the connection timeout (Middleware/ConnectTimeoutSeconds)

Changed

• Improved the documentation of Data Pub/Sub controllers

• Improved the documentation of RPC controllers

Fixed

• The LIN demo does not skip the first entry (sending frame 16) on all but the first iteration through the schedule anymore.

• The name of the domain-socket used by the registry will use the hostname passed in the listen URI, not the resolved IP address (if any), for generating the name of the domain-socket.

• When mixing autonomous participants without time-synchronization, and participants with time-synchronization, the timestamps for messages received before the virtual time is started, is now the ‘invalid’ timestamp value, normally used by participants without time-synchronization.

• Reworked the pause/continue logic such that it pauses the virtual time synchronization without blocking the I/O thread.

[4.0.39] - 2023-11-14

Fixed

• Replaced remaining mentions of integrators with users.

Added

• Usage examples for tracing and replay.

• Timeouts per connection attempt.

• Two-sided connection establishment: Allow direct connections, even if connections are only possible in one direction.

[4.0.38] - 2023-11-02

Fixed

• The dashboard now handles AbortSimulation.

• The dashboard resolves the registry IP address if needed.

Added

• Reintroduced build requirements to documentation

Changed

• Consolidate SIL Kit tests into four executables

[4.0.37] - 2023-10-17

Changed

• Reworked the documentation on Virtual Time Synchronization

• The documentation of the demo section now refers to the pre built Vector SIL Kit packages and not to a source build.

[4.0.36] - 2023-09-19

Added

• Documentation on DashboardUri

Fixed

• Fixed misbehavior of the sil-kit-system-controller in interactive mode on user input:

  • The sil-kit-system-controller now triggers a Stop() in SystemState::Running or SystemState::Paused.

  • The sil-kit-system-controller only triggers AbortSimulation when not SystemState::Running, SystemState::Paused, SystemState::Shutdown or SystemState::Aborting.

Changed

• Performance improvement of the internal serialization

• The final state handling of the sil-kit-system-controller in interactive mode on user input has changed:

  • Old: The sil-kit-system-controller triggered AbortSimulation if the finalState was not received after 5s.

  • New: The sil-kit-system-controller retries receiving the finalState 3x5s. If this fails, the sil-kit-system-controller triggers AbortSimulation (if not already happened) and tries receiving the finalState 3x5s again. If this fails, the sil-kit-system-controller just terminates.

[4.0.35] - 2023-09-04

Added

• Memory management documentation introduced.

• Integration tests for communication in the stop/shutdown/abort handlers.

Changed

• When building the SIL Kit documentation, the sphinx build command is no longer called in a pipenv.

Fixed

• Ensured that calling ISystemController::AbortSimulation() does not lead to the system controller terminating prior to other participants receiving its abort message.

• Ensure that userContext field for external CanFrameTransmitEvents is always null.

• Fixed warning in VS2017 (x86) build

[4.0.34] - 2023-08-21

Changed

• Behavior change of ParticipantState::Error

  • Old: Several situations could lead to an ParticipantState::Error before the user called StartLifecycle()

    • Reception of an invalid WorkflowConfiguration

    • Remote participant disconnected

    • Reception of AbortSimulation

  • New: ParticipantState::Error should only be reached after StartLifecycle() was called

    • Reception of a WorkflowConfiguration is not validated before StartLifecycle()

    • A disconnected remote participant is only transitioned to ParticipantState::Error if he had a started Lifecycle

    • Reaction on SystemCommang::AbortSimulation is deferred before StartLifecycle() (see below)

• Behavior change of SystemCommand::AbortSimulation

  • Old: Reception of AbortSimulation before StartLifecycle() led to ParticipantState::Error

  • New: Reception of AbortSimulation before StartLifecycle() is firstly ignored. A later call to StartLifecycle() then directly leads to an abort (transition to ParticipantState::Aborting, calling the AbortHandler)

• clang presets in CMakePresets.json now have the clang version in their names

• Added an internal barrier between ParticipantState::Shutdown and setting the final state promise. This ensures that the participant state updates are all transmitted while shutting down.

• Revised log messages when shutting down / disconnecting participants

  • Graceful, participant has lifecycle: “Participant <participantName> has disconnected after gracefully shutting down”,

  • Not graceful, participant has lifecycle: “Participant <participantName> has disconnected without gracefully shutting down.”

  • Registry shutdown: “Connection to SIL Kit Registry was lost - no new participant connections can be established.”

  • Participant without lifecycle: “Participant <participantName> has disconnected.”

Fixed

• Made simulation time stop for all coordinated participants when one coordinated participant disconnects ungracefully

[4.0.33] - 2023-08-07

Added

• New experimental extension of the LIN API that allows a user to send frame headers and respond to them without setting up a static configuration beforehand.

• Added link to FMU importer in Readme.md

• Removed internal use of exceptions for failing connections to the registry if another connection mechanism succeeded.

Fixed

• Fixed missing entry of RegistryAsFallbackProxy in YAML schema.

[4.0.32] - 2023-07-19

This is a Quality Assured Release.

Fixed

• Ensure that the registry rejects a connecting participant if a participant with the same name is already connected.

[4.0.31] - 2023-07-10

Added

• Improved Lifecycle and TimeSyncService features:

  • Full support for Operation Mode Autonomous with TimeSyncService including hopping onto / leaving a running simulation

  • Abort simulation in case Coordinated participants want to join a running simulation

  • Abort simulation in case an Autonomous with TimeSyncService sees an incompatible participant

  • Extended integration tests for communication ready guarantees

Fixed

• Fixed a bug in internal barriers where in-between connecting participants could break the communicaiton guarantees

• Fixed transition when aborting from ErrorState, now the state changes to Shutdown like all aborting paths (formery the transition was to ShuttingDown)

• Internal fixes for thread-safety

• Fixed that the SimTask cannot be triggered again after calling ILifecycleService::Stop() in the SimTask

Changed

• CreateLifecycleService with OperationMode::Invalid now throws a ConfigurationError

• Improved documentation on how to run demos in asynchronous mode

[4.0.30] - 2023-06-26

Added

• Added optional timeout mechanism to RPC service.

Fixed

• Fix builds with CMake versions before 3.19

• Fixed crash in SilKitRpcDemo when run with <config> Client --async without a server.

Changed

• SIL Kit Demos (Can, Ethernet, Rpc, Lin, and PubSub) with --async now use an autonomous lifecycle.

• Fixed starting the registry without the --registry-configuration parameter

[4.0.27] - 2023-05-30

Changed

• Added detection of simulation start and end for the dashboard.

  • The simulation id initialization is deferred until the first dashboard relevant event happens.

  • A simulation is considered as ended, when the last participant disconnects.

Added

• SIL Kit Registry (sil-kit-registry(.exe))

  • Support for overriding command line settings via a YAML configuration file

[4.0.26] - 2023-05-22

Added

• Introducing an internal communication barrier between participant states. This happens in the transition from the states ServicesCreated to CommunicationInitializing and from Stopped to ShuttingDown. It leads to extended communication guarantees in the CommunicationReadyHandler, primarily for participants that use the autonomous lifecycle (see the documentation for details).

Fixed

• Corrected spelling mistakes in the documentation

• The dashboard is disabled for cross-builds to QNX, to avoid build errors

[4.0.25] - 2023-05-17

This version was skipped due to compatibility issues with dependent projects.

[4.0.24] - 2023-05-04

Known issue: A LIN transmission by a LIN Slave may have a timestamp that is smaller than the LinSendFrameHeaderRequest of the LIN Master that triggered the Slave response.

Added

• Header-only C++ API implementation following the hourglass-pattern

  • The C++ symbols are still provided by the shared library, but are not used by default anymore

• If a participant cannot establish a direct connection to another participant, it will fall back to using the registry as a proxy for communications with this particular participant

  • Support can be disabled on a particular participant using the new “Middleware/RegistryAsFallbackProxy” field in the participant configuration

Fixed

• Messages are sent in the same order as the SIL Kit API calls that triggered them, regardless of the thread or handler the API calls were executed from. There are no ordering guarantees for API calls that are executed in parallel from different threads.

[4.0.23] - 2023-04-17

Changed

• Added network simulator information to the dashboard REST API

Fixed

• Fixed data type of simulation id returned by the dashboard REST API

• Ethernet and CAN (Trivial Sim.): The self-delivery with TransmitDirection::TX is now triggered only after the frame has been sent with TransmitDirection::RX.

Removed

• Visual Studio 2015 is no longer maintained and therefore not officially supported anymore.

Fixed

• Resolved issue that lead to wrong label matching behavior under certain circumstances.

[4.0.21] - 2023-04-03

Changed

Changed

• Make additional data and rpc information available to the dashboard.

Added

• Added frequently asked questions (FAQ) section to documentation.

• Modification of BenchmarkDemo: Change the communication topology by modifying the PubSub topics. A participant should only send to a single other participant.

• Add LatencyDemo: Measure the average latency between two participants in different processes.

Fixed

• C-API: Fixed a bug where the SilKit_EthernetFrameEvent delivered in the Ethernet frame handler had the userContext field always set to nullptr, instead of the value passed in the corresponding SilKit_EthernetController_SendFrame call.

• C++-API: Fixed a bug where the userContext was set in the frame handlers registered on other controllers than the one calling SendFrame. The userContext is only ever set when a frame event with TransmitDirection::TX is received, which is only possible on the same controller that sent it.

[4.0.19] - 2023-03-02

Changed

• Use function-try-blocks for C-API definitions to reduce indentation and reformat some code for better readability.

Fixed

• Allow installing and starting the sil-kit-registry.exe as a Windows Service on Windows Containers during docker build steps. The layer creation fails if a domain socket is still active during shutdown of the temporary container. Disables the local-domain sockets of the sil-kit-registry.exe when running as a Windows Service.

• When a participant is unable to connect to another participant, the correct error message is logged, and an error is raised.

[4.0.18] - 2023-02-21

Added

• Added descriptions to troubleshooting section for common errors.

Changed

• Complete the Hourglass implementation of the C++ API used internally for testing.

This is a Quality Assured Release.

Fixed

• Fix DNS resolver issues on Ubuntu 18.04 and systemd-resolved. We now properly strip square brackets from IPv6 addresses in URIs.

• Fixed a race-condition in the ITest_SystemMonitor. This caused sporadic failures on CI builds.

Removed

• Removed the deprecated CMakeSettings.json file from the source tree. If you are a developer, use the CMakePreset.json instead which is more portable and flexible.

• Removed usr/share/doc from the delivery packages. This should only be part of Debian packages.

[4.0.16] - 2023-02-03

Changed

• Improved error messages when connections between participants/to the registry have failed.

• CMake: Reduced weak symbols exported in debug builds.

• Allow configuration of acceptor URIs in the participant configuration.

Changed

• PubSub/Rpc: Improved performance in startup-phase when using labels.

• Documentation: Configuration structure for PCAP tracing and replay

Fixed

• LIN: Previously, only when using the network simulator, the FrameStatusHandler on the LIN Master was not called in case of an unconfigured response (RX_NO_RESPONSE). This inconsistency has been fixed.

• Registry

  • The acceptor URIs the known participants list sent by the registry are now rewritten correctly. Previously, certain startup scenarios only worked when the participants were started in a certain order.

• SerDes: Added missing limit library include.

[4.0.12] - 2022-11-24

Fixed

• Integration Tests

  • Linking executables with both, the dynamic library, and certain internal, static library components leads to ODR violations. The ASAN / UBSAN instrumentation from recent Clang versions is able to detect these.

• C-API Tests

  • Fixed some memory leaks in C-API tests.

• LIN

  • Fixed faulty behavior of ILinController::SendFrame() for LinFrameResponseType::MasterResponse. The method now consistently uses the input frame data.

  • Calculates standard deviation for throughput, message rate, speedup

  • Added --write-csv command line argument to output results to csv file

  • Helper scripts for msg-size-scaling and performance-diff

• Changed the lifecycle service to be less verbose in log level info. See log level debug for more detailed information of the lifecycle.

• Updated participant configuration file schema and added it to the json schema support. Use .silkit.yaml/json suffix for automated schema support.

[4.0.9] - 2022-10-19

Added

• The LinDemo, PubSubDemo, and RpcDemo now allow using --async cli flag for unsynchronized execution.

  • fmt to version 8.1.1.

  • spdlog to version 1.10.0.

  • googletest to version 1.12.1.

• The FlexRay controller now issues a warning if the static buffer payload is truncated or padded with zeros, i.e., if the size is not exactly as specified in the controller configuration.

• The registry now transmits a diagnostic string when a participant announcement cannot be processed, e.g., because a participant with the same name already exists. The second participant will not time out after a few seconds anymore, but fail much faster.

[4.0.7] - 2022-09-20

Changed

• The documentation is now packaged separately in a SilKit-4.0.7-Docs.zip file. This simplifies the CI set up and reproducibility of the generated HTML. To build the documentation you should set up the build environment using pip:

  pip3 install -r SilKit/ci/docker/docs_requirements.txt
  

• The source tree is now packaged separately in a SilKit-4.0.7-Source.zip file. The SIL Kit Demos are part of this package.

• We no longer have a #if defined(HAVE_FMT) in the silkit/services/logging/ILogger.hpp and variadic logging functions. This define was disabled by default for users and only used internally.

• LIN allows sending with an unknown checksum model in master responses, now.

• The Pub/Sub Demo was updated to use the internal serialization/deserialization routines.

Fixed

• Fix building and linking on macOs. This platform is not part of the continuous test suite.

[4.0.6] - 2022-09-06

Changed

• Removed an empty directory from the packages

• Updated the description of SIL Kit in the top-level README.rst

Fixed

• Clean up peers after a remote participant disconnects

[4.0.5] - 2022-08-25 Initial public release (quality assured release)

This is the first public open source release of the Vector SIL Kit.

Starting with this version, Vector SIL Kit will provide longterm API, ABI, and network compatibility. Note that prior versions do not provide this compatibility.

[4.0.4] - 2022-08-22

Compatibility with 4.0.3

• Application binary interface (ABI): Yes

• Application software interface (API): No

• Middleware network protocol: No

Changed

• Utility (SerDes)

  • SilKit/include/silkit/util/serdes/Serialization.hpp:

    • The media type for PubSub was changed from application/vnd.vector.sil.data; protocolVersion=1 to application/vnd.vector.silkit.data; protocolVersion=1

    • The media type for RPC was changed from application/vnd.vector.sil.rpc; protocolVersion=1 to application/vnd.vector.silkit.rpc; protocolVersion=1

• LIN

  • SilKit_LinChecksumModel_Undefined was renamed to SilKit_LinChecksumModel_Unknown.

• C: Orchestration

  • SilKit_LifecycleService_Stop was added to the C-API. This corresponds to SilKit::Services::Orchestration::ILifecycleService::Stop.

• C: Ethernet

  • Frames delivered in user-provided SilKit_EthernetFrameHandler functions had an invalid payload delivered. This was fixed, the frame is now correctly delivered. The error only occured in the C API, the C++ API correctly delivered the entire frame.

[4.0.3] - 2022-08-22

Compatibility with 4.0.2

• Application binary interface (ABI): No

• Application software interface (API): No

• Middleware network protocol: Yes

Added

• LIN

  • SilKit/include/silkit/services/lin/ILinController.hpp:
