- Allow setting ReturnDiagnostics on the session factory to ensure the diagnostic settings are part of "Create" also. Set them to SymbolicIdAndText by default.
- Better logging in unit tests, now also logs to progress including exception traces, also prefixes SERVER and TEST on console to attach the logs to the server or client side.
- GDS client stability improvements to ensure client reliably reconnects between calls when connection is lost.
- Do not dispose the application certificate when it is updated from GDS client to avoid existing sessions to crash with CryptographicException. This needs more improvements later on because it is rather hacky today.
- Remove the certificate cache in CertificateFactory (as per discussion and agreement) which allowed re-enabling the older UserIdentity API
- Logging improvements here and there to analyze issues in unit tests better
Update the function to improve performance.
Fix test code warnings (CA1305) related to ToString() method
Based on the results of the benchmark runs, `EscapeStringLegacyPlus` was picked for all platforms that do not support `StreamWriter.Write(ReadOnlySpan<char>)`, e.g. .NET Framework. There is a slight improvement for the cases which require a 4 digit hex encoding.
For platforms that support Span end to end `EscapeStringSpanCharsInline` was picked. The functions tries to optimize how often the underlying StreamWriter is called by combining calls to Write into to slices. It was also noted that up to three character strings, it performs better to do single character writes than calling with a small string.
- bug: if the nested complex type is derived from an abstract type like a Union, the decoder uses the abstract type instead of the actual type to decode
- fix: the loop to determine the supertype of the type to be decoded stops too early and returns an invalid type reference, e.g. for Unions. Instead the loop will now continue until a valid BuiltInType or a Structure or Enumeration type is found.
- improve various log messages, comments etc.
- multiple internal improvements in naming convention handling of async functions
- add FetchSuperTypesAsync
- replace new UTFEncoding() with Encoding.UTF8 singleton
- Add the system diagnostics library for unsupported target platforms
- Integrate in clientfixture by adding IDisposable to support to enable/disable the activity tracing
- fix Traceable session dispose issue, do not null the disposed session
- Add traceable client session with factory to support ActivitySource on .NET 6
- Only traces the public API calls, inner calls are not yet supported.
- Uses the name: Opc.Ua.Client-TraceableSession-ActivitySource
- The StructureValue DataType value has a Method and event as childs, but it may only have variables / properties.
- Uses latest generated code from Modelcompiler which fixes issues with child variables read/write/monitoring.
- Deprecate support for Nuget package support of .NET Framework 4.6.2
- Bump sample applications to 4.8
- update some copyright headers / supporting files (editorconfig etc.)
- fix a few warnings
- fix an issue with `SessionReconnectHandler`, in certain combination of reconnect period and exponential backoff the .NET sample app never reconnected.
A discovery only channel only accepts discovery service calls. The type of service call should be checked before the message is parsed.
- Add a check for discovery message before the chunks are decoded.
- Add a check that discovery service call are below a restricted message size (e.g. 64k).
- Add a test case.
The changes add an API to ComplexTypeSystem to retrieve data type definitions that were created during type building to leverage them to build DataSetMetaDataType for OPC UA PubSub.
The changes include the following:
* Combine all conversion of enumerations into EnumDefinition and use the resulting to build the type
* Remove all other API from the type builder interface and implementation.
> The assumption is that these interfaces are used internally and removal will not cause a breaking change.
* Combine everything previously covered elsewhere into existing AddEnumType function.
* Add a NodeIdDictionary cache and fill that cache during load, as well as API to retrieve the data type definitions
Expose an 'ISession' interface as abstraction to ease unit testing.
Breaking changes are kept to minimal impact, but some changes maybe required to use ISession objects instead of Session.
Note: ISessionClientMethods is hand created, not yet by ModelCompiler
- Doc, docs, docs updates for new 368 support
- fix a missing null pointer check when ConditionRefresh is run
- Ref server: move NodeManager factory API to StandardServer, decoupling the NodeManager implementation from Ref server
- Ref server: add shadow mode flag, to allow to map a docker configuration in a mapped folder.
- Ref server: sample batch files how to run Github CR and local docker images
- Improve some misleading 'delete application certificate' log messages.
- For EventSource and legacy logger refactor logging to support the built in LogValueFormatter, which provides the format strings suitable for `string.Format`.
- **Breaking change**: For `TraceEvent` this is a breaking change, because there is no implementation yet to support to provide the reformatted format string. With this implementation if a logging framework is used which supports the semantic logging, there is no issue. With frameworks which do not understand semantic logging strings(e.g. log4net) it is a breaking change, string.format will throw exceptions --> move to ILogger hook using `SetLogger`.
- **Warning**: When Microsoft.Extensions.Logger based loggers are used, format strings must follow this convention:
i) All variable entries must follow order and count up, e.g. "{0} -- {1}" etc., no mix of "{2}--{0}"
ii) in the same way the args must follow this strict ordering.
- Format strings will be changed by future PR to include the semantic values.
- fix the complex types of the test nodeset (requires https://github.com/OPCFoundation/UA-ModelCompiler/pull/96)
- improve some client / server tests
- add tests for complex types datatype definition integrity on ref server, validate bsd and xml dictionaries in the test server (open issue: https://mantis.opcfoundation.org/view.php?id=7393, xml validation always failing)
- improve server fixture, to allow for custom config changes
- fix an issue that caused kestrel not start on windows/.NET Core 3.1 and above, when a new certificate was issued, thereby ignoring all https client tests.
