Revision history for Perl extension OPCUA::Open62541.
2.00 2023-02-10
- Use methods ServerConfig::setDefaultWithSecurityPolicies()
and ClientConfig::setDefaultEncryption() to activate encryption
and optionally verfication on both sides respectively.
- Module OPCUA::Open62541::Test::CA is used to create private
key, certificate, CA and CRL for testing OPC UA encryption.
- Implement methods to get and set client and server description
in open62541 config.
- Generate OPC UA constants in Perl from open62541 version 1.3.4
with full namespace 0.
- Remove support for open62541 1.0 and 1.1 API. 1.2 branch did
not work properly with OPCUA::Open62541 anyway. Minimum
required version of the open62541 library is 1.3 now. open62541
master branch has issues. OPCUA::Open62541 tests currently
run and pass with open62541 version 1.3.4.
- A lot of backwards compatibility code in implementations and tests
has been removed.
- The 1.0 API compatibility of the client getState() method has
been removed. It has to be called in list context now to
retrieve channel state, session state, and connect status.
Trying to retrieve the client state in scalar context will
result in a Perl die. A client state does not exist anymore.
- Implement basic encryption for client and server. Certificates
are not validated yet.
- Improve behavior of client config setUsernamePassword()
method.
1.05 2022-10-27
- Create correct SIGNATURE file.
1.04 2022-10-27
- github CI is building open62541 version 1.0.6, 1.1.6, 1.3.3.
Test with open62541 master does not terminate, disable for now.
- Include patch for the open62541 1.0.6 sources that allows to
generate the Open62541-packed XS file.
- Major rewrite of XS pack and unpack functions. The nested
Perl hashes and UA objects are linked together before they
are filled with values. If the latter croaks in the middle
of packing or unpacking, the partially created object has
references to the part that succeeded. So destruction of the
object can free the sub structures. This avoids memory leaks
in error cases.
- Set build info leaked the build info that was set before.
- Fix memory leak in variant get scalar and get array error
case.
1.03 2022-07-19
- github CI is building open62541 version 1.0.6, 1.1.6, 1.3.2,
and master. 1.2 tests fail and there is no goal to fix them.
Remove version 1.2.5 from CI.
- Allow to set username and passwort in the client config.
1.02 2022-07-09
- Fix reference counting with server node lifecycle callbacks.
The behaviour in open62541 has changed, use heuristic to free
Perl SV. Use common code for all server add node functions.
- Adapt client subscription callback to open62541 API 1.1.
- Test for source timestamps and async read value accept also
behavior of newer open62541.
- Behavior of Perl node context in constructor and destructor
has changed so that it can work with both old and new open62541.
- Connect and disconnect behavior has changed in subtle ways,
especially in the async case. Tests tolerate more variations.
- To call the client state callback with a valid Perl client
variable, update the client context more often to current SV.
Due to different callback behavior, this became an issue with
newer open62541.
1.01 2022-06-17
- Adapt client iterate timeout to 32 bit for open62541 API 1.1.
- Use the SECURECHANNELSTATE constants from API 1.1 and 1.2.
- Use magic STATUSCODE in clientStateCallback().
- Avoid double free when destroying client config.
- Test server starts with API 1.3.
- Implement client async connect and disconnect with API 1.1.
- Test client works with API 1.1.
- Server config provides setCustomHostname() or setServerUrls().
- Allow float values Infinity and NaN.
1.00 2022-05-30
- Bump major version. OPCUA::Open62541 compiles with open62541
version 1.0.6, 1.1.6, 1.2.4, 1.3. While this is enough to
be API compatible with all versions, the tests fail from API
1.2 on. Do not expect a working open62541 wrapper for anything
else than the old 1.0 API.
- Switch to X.YY version number format. Three minor digits are
not needed.
- Generate and merge constants for 1.0 and 1.3 API.
- Optionally support highlevel client async interface of 1.3 API.
- 1.3 API removed Server Config set Custom Hostname function.
- 1.3 API removed typeIndex from UA_DataType, use pointer
arithmetic as workaround.
- Use github CI runner to build and test with open62541 API
1.0, 1.1, 1.2, and 1.3.
- Regenerate ppport.h with Devel::PPPort version 3.64.
0.029 2021-08-13
- Cleanup monitored item delete callback, newer open62541 behaves
differently. Cover both cases.
- Fix memory leak when creating monitored items.
- Introduce MonitoredItemArrays to handle callback memory
in UA_Client_MonitoredItems_createDataChanges() and
UA_Client_MonitoredItems_createDataChange(). This should
plug all memory leaks and use after free with these callbacks.
0.028 2021-08-09
- Use specific structs to store subscription context and monitored
item context.
- Pass subscription context to monitored item callback.
- Fix memory management of MonitoredItemCreateRequest_default().
0.027 2021-07-29
- Implement wrapper for subscription functions of open62541.
- Call back change and delete notifications to Perl.
- Call back multiple monitored items change and delete to Perl.
0.026 2020-09-30
- Fix memory leak in server add node methods.
0.025 2020-09-17
- Add missing functions documentation.
- Implement server config methods:
getMaxNodesPerRead(),
setMaxNodesPerRead(),
getMaxNodesPerWrite(),
setMaxNodesPerWrite(),
getMaxNodesPerMethodCall(),
setMaxNodesPerMethodCall(),
getMaxNodesPerBrowse(),
setMaxNodesPerBrowse(),
getMaxNodesPerRegisterNodes(),
setMaxNodesPerRegisterNodes(),
getMaxNodesPerTranslateBrowsePathsToNodeIds(),
setMaxNodesPerTranslateBrowsePathsToNodeIds(),
getMaxNodesPerNodeManagement(),
setMaxNodesPerNodeManagement(),
getMaxMonitoredItemsPerCall(),
setMaxMonitoredItemsPerCall().
0.024 2020-08-28
- Implement server config setBuildInfo().
0.023 2020-08-24
- Implement server config methods:
setUserRightsMaskReadonly(),
setUserAccessLevelReadonly(),
disableUserExecutable(),
disableUserExecutableOnObject(),
disableAddNode(),
disableAddReference(),
disableDeleteNode(),
disableDeleteReference(),
disableHistoryUpdateUpdateData(),
disableHistoryUpdateDeleteRawModified().
This allows to setup a server that provides read-only data.
0.022 2020-08-17
- Implement setStateCallback() and call Perl from callback.
- Implement client config get and setClientContext().
- Implement server browseNext().
0.021 2020-07-28
- Implement generic server read().
- Implement server config get and setMaxSecureChannels().
0.020 2020-07-13
- Make compilation of constant defines optional.
- Implement generic server write() method.
0.019 2020-06-30
- Fix XS unpack for extension object, write data to C structure.
0.018 2020-06-25
- Implement array dimensions for variant.
- Set value rank in test server complex objects.
0.017 2020-06-23
- Implement createOptionalChild and generateChildNodeId global
node lifecycle callbacks.
- Make pack and unpack of ExtensionObject consistent.
- Fix lifecycle spelling.
- Code reference to client callback is stored as a copy.
- Implement global node lifecycle destructor. Node context
can be changed in constructor and is accessible from destructor.
- Store config in server and client object from the beginning.
0.016 2020-06-18
- Implement configuration of server session limits. Server
config has methods getMaxSessions(), setMaxSessions(),
getMaxSessionTimeout(), setMaxSessionTimeout().
- Remove server newWithConfig() constructor. The 1.1 API
would require a different implementation, but it is not used
anyway.
- open62541 has released version 1.1 of their library. The
new API is slighlty different. Update github CI to ubuntu-20.04
and implement enough XS so that all tests are passed or
skipped. This makes p5-opcua-open62541 work with both 1.0
and 1.1 open62541. Use Devel::CheckLib to find features of
the library and add #ifdef to compile a working variant.
Async connect works with 1.0 API only.
- Start adding global node lifecycle callbacks. Only the
constructor callback has been implemented yet. Using the
node context does not work.
- Pack and unpack Guid to formated Perl string as in Part 6,
5.1.3. of the OPC UA specification.
- During unpack of integer and float values, croak if an overflow
is detected. This is better than a warning that nobody reads.
- Provide pack and unpack functions for full namespace 0 if
the open62541 library has been built with this option.
- Set admin session context to provide a context for the global
node lifecycle callbacks. Implement server setAdminSessionContext()
method.
- Fix memory leak when server object is destroyed.
0.015 2020-05-29
- Implement client sendAsyncReadRequest() as it is missing
in open62541 API.
- Implement client/server read/write DataType. They cannot
be generated as DataType needs special conversion to NodeId.
- UA_Server_readContainsNoLoop contains typo, provide
server readContainsNoLoops wrapper.
- Genearalize script client-server-read-write.pl
to generate all client/server read/write functions.
- Generate wrapper for all server read and write functions.
- Generate client write wrapper functions.
- Generate client readDataTypeAttribute() function.
0.014 2020-05-13
- Server build info is copied to return value and uses regular
typemap clear.
- The NULL string and NULL byte string is unpacked from undef.
Perl undef has a meaning different from "" and is represented
in the open62541 objects.
- Use Test::Strict to check all Perl source files. This is a
new test dependency.
- Generate all client read XS wrapper functions with a script.
This includes the regular and async methods and the callback
with the matching return value for each type. The
readDataTypeAttribute functions are implemented manually as
they have to convert NodeId to DataType before providing the
output value.
- Memory management for all input and output parameter is done
in the typemap. Except for DESTROY destructors the XS functions
do not call clear() or delete() anymore.
- Better error message for missing mandatory parameter.
- The typemap identifies the reqId parameter as optional
output parameter by its new name outoptReqId.
- Implement client sendAsyncBrowseNextRequest() as it is missing
in open62541 API.
- Code scanner cppcheck passes with C code generated from XS.
- Test server setup_complex_objects() method can handle name
space, access level, and got various other improvements.
- An empty UA_Variant is now represented as an empty Perl hash.
- The open62541 parameters of the XS functions are allocated
in the typemap and stored as mortal Perl objects. Now Perl
is responsible to free them. The open62541 objects are deleted
in the Perl destructor. The XS wrapper functions do not have
to care about calling clear() or delete() anymore.
- Server add node functions fill output parameter outNewNodeId
as hash.
- Parameter passing to XS functions is stricter. The typemap
does all the checks at a central place.
- Add more than 100 test cases for all possible typemap
conversions of the input paramteter.
- Test Unicode conversions in XS packed functions, Perl hashes,
and YAML output. YAML::Tiny is a new test dependency.
- In the XS functions the open62541 output value has to be
cleared after converting it to an SV. This fixes a memory
leak.
- In the XS functions the temporary open62541 parameter objects
have to be cleared before return. This fixes a memory leak.
- Setting scalars or arrays in a variant passes the reponsibility
for memory lifetime to the open62541 library.
- Memory for strings and byte strings is allocated dynamically.
Reusing the Perl data does not allow sane lifetime management.
- The unpack conversions use UA_Array_new() instead of calloc(3)
to construct arrays.
- Remove LocalizedText new() constructor, it was never used.
0.013 2020-05-01
- Remove Makefile from MANIFEST and skip it.
[rt.cpan.org #132463] No rule to make target
0.012 2020-04-30
- Fix signal race in test server.
- Use test server planning_nofork() to compute test numbers
of non-forking server tests.
- Implement server browse(), deleteNode(), addReference(),
deleteReference().
- Improve test client usability.
- Use the github continuous integration framework to build the
module and run tests on a Ubuntu VM.
- In client-connect-async test, skip the subtests that trigger
an freeaddrinfo bug of open62541. The bug is fixed in the
OpenBSD port, the test is skipped elsewhere.
- Implement server getBuildInfo().
- Implement server addNamespace().
- Plug memleak in variant setScalar() and setArray().
- Make error messages in croak consistent.
- The type constants depend on the compile options of open62541.
Do not check in these numbers in Perl files, but generate C
functions that evaluate them during Open62541.xs compile time.
Table with type conversion must not assume that the type
numbers are continuous. This makes the module work with
precompiled open62541 library on GNU/Linux.
- Avoid compiler warnings with GCC.
- Fix test races seen on GNU/Linux.
- Improve test logger diagnostic output.
0.011 2020-04-24
- Test client and server can use a custom log file.
- Improve signal handling in test server.
- Implement test server runtime actions.
- Implement server functions to read and write values:
readValue(), writeValue()
- Implement more server functions to add nodes:
addVariableTypeNode(), addObjectNode(), addObjectTypeNode(),
addViewNode(), addReferenceTypeNode(), addDataTypeNode()
- Implement client function Service_browse().
- Add prefix to QualifiedName hash keys.
0.010 2020-04-20
- Make single stepping the test server actually work.
0.009 2020-04-17
- Embed config and logger struct into client or server. This
avoids malloc() and free() races. The config and logger may
extend the lifetime of client or server.
- No stand alone logger is possible anymore. The Logger->new()
method has been removed from the API.
- After connect_async() the client needs 100 miliseconds before
client run_iterate() may be called. Add some sleeps to test.
- Move C declarations to PREINIT section.
- The test server can single step iterations to trigger timing
races in client tests.
0.008 2020-04-14
- Fix double free in set variant.
- Test cleanup.
- Variant can get and set array type.
- Generate correct version number in OPCUA::Open62541::Constant.
- Add NODECLASS constant.
0.007 2020-04-06
- Fix memory leak in callback_async() and extend leak tests.
The API does not invoke the connect callback in case of error.
This requires special code to track the call data and to free
it during destroy.
- Implement UA_Client_readValueAttribute_async().
- Implement client disconnect_async().
- Add missing functions to pod documentation.
- Test request id of async browse request.
0.006 2020-03-27
- Remove server config clean() function from Perl API.
- To run a test server manually, the timeout can be disabled.
- Use Test::EOL to find trailing whitespace.
- Generate constants from defines and enum in C header file.
- Export constants from OPCUA::Open62541 into namespace.
This breaks the existing API how modules are used and imported.
Especially NS0ID uses underscore and new names are incompatible.
- Place all generated constants into a single Perl module
OPCUA::Open62541::Constant.
0.005 2020-03-12
- Plug memory leaks in connect_async() in sendAsyncBrowseRequest(),
which were found by the tests.
- Allow to iterate client from test framework.
- Croak if wrong output variable type, make API stricter.
- Print log level and category as string with magic variables.
- Write client log files to debug tests.
- Improve leak ckecks in tests.
- Refactor client and server tests.
- Avoid posix signal handler in test server.
- Grep for server startup in server log to avoid races in tests.
- Test server writes log file.
- Implement Logger class.
- Refactor client callback.
- In XS croak() print function name and errno strings.
0.004 2020-02-27
- Use perlcritic and perltidy.
- Test that adding a node in the server and reading its value
from the client works.
- Use an efficient way to export constants in Perl namespace.
- Implement UA_Client_readValueAttribute().
- Use a function jump table for packing all variant types.
- Make this module run on multi threaded Perl by sprinkling dTHX
into the XS file.
- UA_DiscoveryConfiguration and UA_FilterOperand croak when
trying to pack them.
- Implement all missing packed functions for builtin types.
- To test client and server easily, implement
OPCUA::Open62541::Test::Server and OPCUA::Open62541::Test::Client
to handle the other end.
0.003 2020-02-21
- OPCUA::Open62541::sendAsyncBrowseRequest() uses optional output
variable for request id.
- Run static code analyse with cppcheck, remove false positives.
The C code generated by XS is clean.
- Use the generated VariableAttributes packed functions.
- Implement sendAsyncBrowseRequest for client.
- Implement OPCUA::Open62541::Variant->setScalar() and ->getScalar().

- Implement type conversions for setting scalars in variant type.
- Connect client to server.
- Implement client and its config.
0.001 2020-02-12
- Implement basic functions needed to build a simple OPC UA server.
That is "4.2 Building a Simple Server" and "11.2 Server Lifecycle"
from the open62541 1.0.1 library documentation.
