* Use "definition" signal meta-data json-object to Encode/Decode signal descriptor fields
* Change the order of protocol meta-data messages - send/handle list of "available" signals first
and meta-data of subscribed signals second
* Set the default data value Range {-15.0, 15.0} for signals of non-openDAQ ("fusion") devices,
to be applied for auto-scaling the renderer window size
* Set-up Unit objects for descriptors of mock signals used in tests
* Client sends subscribe requests for all available signals
* Remove order dependency for receiving of time/value signal meta-data in ws streaming * Fix websocket streaming for scenarios when tableId does not equal to signalId * Use ws streaming protocol absoluteReference meta as signal origin
* <TBBAS-906> Signal/Streaming framework: Automatically subscribing mirrored signals
when signal has at least one connection to the InputPort
and unsubscribing when the connection count decreases to zero.
* <TBBAS-905> Native streaming: Subscribing domain signals automatically by client side
when value signal is being subscribed.
Adding/Removing reader on server side when signal is being subscribed/usubscribed
* Streaming framework refactoring:
SignalRemote renamed to MirroredSignalConfig for interfaces and smart pointers
IMirroredSignalConfig inherits ISignalConfig
Streaming source management methods moved from ISignalConfig to IMirroredSignalConfig
Streaming and MirroredSignal implement additional private interfaces
Mirrored signal gets initial DataDescriptorChanged EventPacket directly from active streaming source
* Drop received descriptor changed event packets by native streaming client if descriptors was not actually changed * Make access to cached signal descriptors thread safe in streaming clients
* local signals - setting is ignored * mirrored signals - subscription status is bound to 'streamed' setting and the existence of listeners
* 'WebsocketControlPort' property added to websocket streaming server config * streaming server utilizes control server implementation from streaming-protocol-lt library * server subscribes signals only if request received from client
TODO: Add OPC UA support
* pseudo device can be alternatively connected using raw tcp sockets by prefix 'daq.tcp://'
… prevent ICEs and out-of-heap-space errors
* subscribe/unsubscribe client signals which connected/disconnected to/from InputPort
* temporarily subscribe all available signals during streaming connection initialization
* Immediate addition of a reader upon signal subscription. * Immediate removal of a reader upon signal unsubscription.
- adding Instance Builder - adding method InstanceFromBuilder - expand instance tests with checking instance builder - update changelog - add description of Instance configuring in doc
Search filters, visible flag, component attributes - Add SearchFilter that allows for more granular component search on tree traversal methods (getItems, getSignals...) - Add visible flag to Component - Default component getters were modified to return only components with visible==true - PropertyChanged event packets were removed - ComponentModified core event was changed to AttributeModified - Attribute lock was added to components preventing changes to locked attributes - Name and Description are no longer properties, but component attributes - Add per-component core event triggers
…eaming client: * Allow multiple data signals to have same `tableId` * Add client handling of domain signals listed as available * Add `MockStreamingServer` implementation used in tests to bypass the creation of artificial time signals within the streaming-lt library * Expand the WebSocket pseudo device test suite with the relevant tests
…e config protocol. * Additions: - encoding/decoding of native config packets within the native transport protocol. - support for a new device type in the native client module. - native config protocol support in the native server module. - a minimal set of integration tests. * Fixes: - serialization of signal descriptors. - fix mutex lock issues in mirrored signals implementation upon subscribe/unsubscribe. - assign domain signals for deserialized signals.
…te utility functions
…openDAQ#556) - Implement protocol version info - Broadcasting protocol version via mDNS - Add transferring the connection string path from server
* MacOs skipped tests * Some excluded parametrized integration tests * Tests skipped due to IPv6 unavailability
* Delete the fields `id`, `name`, and `versionInfo` from the `IModule` interface and add them to the new `IModuleInfo` interface, which is a new field in the `IModule` interface * `IModuleInfo` field is also added to `IComponentType` interface * Works over Native * Component Type is moved from `coreobjects` to `opendaq`
* Bump year in license, etc. to 2025 * Update additional files
* shared libraries:
- <TBBAS-1920> & <TBBAS-1923> extend MDNS discovery server and client
to enable transmitting the custom non-discovery packages
- Automatically advertise the ip-modification service within mdns discovery server
if IP-modification is enabled within instance
* core:
- enable passing the root device reference to mdns servers
* external dependencies:
- Add patch for header-only mdns library to support custom non-discovery queries
- Rename and extend parameters of mdns query callbacks
* Discovery refactoring:
- replace dependency on opendaq to dependency on coreobjects lib
- replace modules callbacks with direct instantiation of DeviceInfo object using discovered device data
- Rename services to servers for discovery
- Move duplicating discovery and ip modification code into common library
* Simulator:
- Enable changing and retrieving IP config on simulator over netplan
- Fix getting RefDevice SerialNumber from module options <TBBAS-2044>
- Update vagrant installation for standalone build-packages ci job
- Replace Avahi with internal mDNS server for OPC UA discovery
- Remove Avahi from simulator and clean-up it's dependencies
- Reduce simulator boot time when network is offline
* Add cpp and python examples for IP modification
* Fix unused variable warning in reader bindings
…iting of read-only values (openDAQ/openDAQ#700)
Fix LT streaming issues (openDAQ/openDAQ#696) * keep client session open when unknown or incomplete signal's data received <TBBAS-2084> <TBBAS-1996> * use raw Json value of linear rule delta when creating linear rule parameters <TBBAS-2013> * utilize default start value for generating constant rule signal <TBBAS-2049> <TBBAS-1974> * properly accept control connections via IPv4/v6 <TBBAS-2085>
