Remove a misleading comment about the content of the variable
externalDataValue in the PubSub beforeWrite callback.
The beforeWrite callback is called with the data pointer containing the
data before the update. It may be used for a double buffer
implementation.
The original code change that changed the usage of the beforeWrite
callback was done with commit
06da5d07bd.

* PubSub beforeWrite callback
|
|
|
|
A misleading comment about the content of the variable
|
|
externalDataValue in the PubSub beforeWrite callback has been
|
|
removed. Please review your beforeWrite callback implementation.
|
|

containing the data before the update. It may be used for a
|

double buffer implementation.

* Decoding variant with array of structure
|
|
|
|
When decoding an array of structures the extension objects that
|
|
each structure is wrapped into is now unwrapped if the array
|
|
contains only a single type. Previously the decoding API returned
|
|
an array of extension objects. If the array of extension objects
|
|
has more than one type the decoding result will be an array of
|
|
extension objects.

* KeyValueMap in PubSub configuration
|
|
|
|
The UA_KeyValueMap structure is used everywhere instead of raw
|
|
arrays of UA_KeyValuePair.

* Thread-safe client
|
|
|
|
A large portion of the client API is now marked UA_THREADSAFE. For
|
|
those methods, if multithreading is enabled, an internal mutex
|
|
protects the client.

* Saving unknown client certificates
|
|
|
|
'UA_CertificateVerification_CertFolders()' has been extended with
|
|
an additional parameter - path to the folder where the rejected
|
|
certificate should be stored. This change applies if
|
|
`UA_ENABLE_CERT_REJECTED_DIR` is set.
|
|
|
|
The change was done with pull request #5260.

|
* JSON decoding based on JSON5
|
|
|
|
The JSON decoding can parse the official encoding from the OPC UA
|
|
specification. It now further allows the following extensions:
|
|
|
|
- The strict JSON format is relaxed to also allow the JSON5 extensions
|
|
(https://json5.org/). This allows for more human-readable encoding
|
|
and adds convenience features such as trailing commas in arrays and
|
|
comments within JSON documents.
|
|
- If `UA_ENABLE_PARSING` is set, NodeIds and ExpandedNodeIds can be given in
|
|
the string encoding (see `UA_NodeId_parse`). The standard encoding is to
|
|
express NodeIds as JSON objects.
|
|
|
|
These extensions are not intended to be used for the OPC UA protocol on the
|
|
network. They were rather added to allow more convenient configuration file
|
|
formats that also include data in the OPC UA type system.

* LocaleId support in the server
|
|
|
|
The server now supports that descriptions and display names for
|
|
different locales are written to a node. The server selects a
|
|
suitable localization depending on the locale ids that are set for
|
|
the current session.
|
|
|
|
Locales are added simply by writing a LocalizedText value with a
|
|
different locale. A locale can be removed by writing a
|
|
LocalizedText value of the corresponding locale and with an empty
|
|
text.
|
|
|
|
The change was done with pull request #4165.

* PubSub publisher id types
|
|
|
|
The union for the PubSub publisher id 'UA_PublisherId' and
|
|
the enumeration for the PubSub publisher type 'UA_PublisherIdType'
|
|
have been changed to support all specified publisher id types.
|
|
|
|
The change was done with pull request #5223.

* PubSub state change functions
|
|
|
|
The following functions in ua_pubsub.h have been extended with
|
|
an additional parameter for the cause of the state change.
|
|
Moreover the parameter order has been changed.
|
|
UA_DataSetWriter_setPubSubState
|
|
UA_WriterGroup_setPubSubState
|
|
UA_DataSetReader_setPubSubState
|
|
UA_ReaderGroup_setPubSubState
|
|
|
|
The change was done with pull request #5162.

|
* Server port and hostname configuration
|
|
|
|
Instead of configuring the port number in the server's
|
|
"NetworkLayer", the server configuration now takes a list of
|
|
ServerURLs like `opc.tcp://my-server:4840` or
|
|
`opc.wss://localhost:443`. The URLs are used both for discovery
|
|
and to set up the server sockets based on the defined hostnames
|
|
(and ports).
|
|
|
|
The default is to listen on all interfaces with port 4840 for
|
|
incoming TCP connections.

* Empty arrays always match the array dimensions
|
|
|
|
We consider empty arrays (also null-arrays) to have implied array
|
|
dimensions [0,0,...]. So they always match the array dimensions
|
|
defined in the variable. With this, the initialization of
|
|
variables without a defined value has been simplified.
|
|
We now create a null array if one is required.
