* Added callback API for extending the basic Device object and children with proprietary properties for ReadProperty and WriteProperty services. The callback API includes a function to get the specific proprietary property list for any specific object instance in the device, functions to handle the ReadProperty or WriteProperty of the proprietary property.
* Added a new property_list_function typedef to proplist.h for proprietary property list callbacks
* Removed the object-specific proprietary property implementation from the Loop object
* Added test coverage in the Device test validating the proprietary property API usage
* Added CreateObject and DeleteObject for basic Accumulator objects.
* Added WriteProperty handling for object-name, scale, out-of-service, units, and max-pres-value.
* Added Blink.Callback and Blink.Priority to support end-of-blink actions for WARN_OFF/WARN_RELINQUISH. The Blink.Callback is invoked when a blink sequence ends or when a new command interrupts a WARN_OFF/WARN_RELINQUISH in progress.
* Added Lighting Output (LO) WARN_OFF/WARN_RELINQUISH post-egress priority array handling using the Blink.Callback
* Added enumeration text lookup for BACnetAuthenticationStatus, BACnetAuthorizationMode, BACnetAccessCredentialDisable, BACnetAccessCredentialDisableReason, BACnetAccessUserType, BACnetAccessZoneOccupancyState, BACnetWriteStatus, BACnetIPMode, BACnetDoorValue, BACnetMaintenance, BACnetEscalatorFault, BACnetEscalatorMode, BACnetEscalatorOperationDirection, BACnetBackupState, BACnetSecurityLevel, BACnetLiftCarDirection, BACnetLiftCarDoorCommand, BACnetLiftCarDriveStatus, BACnetLiftCarMode, BACnetLiftFault, BACnetLiftGroupMode, BACnetAuditLevel, BACnetAuditOperation, BACnetSCHubConnectorState, BACnetSCConnectionState, BACnetNodeRelationship, BACnetAction, BACnetFileAccessMethod, BACnetLockStatus, BACnetDoorAlarmState, BACnetDoorStatus, BACnetDoorSecuredStatus, and BACnetAccessEvent.
* Created BINARY_PV_MAX with the same semantic meaning as one more than the last valid enumeration, and deprecated MAX_BINARY_PV usage in the examples.
* Reduced code size by using bactext_property_states_strtoul() instead of individual API for each enumations.
Added a new API for writable property lists across all the basic example object types, preparing for the introduction of a Writable_Property_List property in every object in a future BACnet standard revision.
The lists can be used by backup and restore feature to automatically choose the object property values in the backup that can be restored via internal WriteProperty directly from BACnet CreateObject services with List of Initial Values.
Updated existing device object examples to include these writable property lists.
* Fixed lighting output object lighting-command last-on-value to only
be updated with the last value of the Present_Value property that
was greater than or equal to 1.0%, keeping in mind that the Present_Value
shall indicate the target level of the operation and not the current
value.
Fixes the CreateObject service list-of-initial-values encoding and decoding by refactoring the data structure to be similar to WriteProperty. The implementation changes from using a linked list of property values to using a flat buffer approach with delayed decoding.
Changes:
* Refactored BACNET_CREATE_OBJECT_DATA structure to use an application_data buffer instead of a linked list for initial values
* Added a new create_object_process() and create_object_initializer_list_process() functions to centralize object creation logic and error reporting
* Updated all device implementations to use the new centralized creation functions
* Enhanced the create-object example application to support command-line specification of initial property values
* Added comprehensive test coverage for the new encoding/decoding and processing functions
* Fixed BACnet file object path name unintended path traversals by optionally restricting path name content with BACNET_FILE_PATH_RESTRICTED define.
* Added POSIX file path name checking for AtomicReadFile and AtomicWriteFile example applications. Prohibits use of relative and absolute file paths when BACNET_FILE_PATH_RESTRICTED is non-zero.
* Fixed tokenizer_string() off-by-one buffer overflow when processing string literals longer than the buffer limit.
* Fixed ubasic potential string buffer overflows by using snprintf instead of sprintf.
* Fixed ubasic label strings to use UBASIC_LABEL_LEN_MAX as buffer limit.
* Fixed ubasic string variables to initialize with zeros.
* Fixed compile errors when UBASIC_DEBUG_STRINGVARIABLES is defined.
* Added ubasic string variables user accessor API and unit testing for ubasic string variables.
* Fixed tokenizer_label() off-by-one buffer overflow when processing string literals longer than the buffer limit.
* Fixed lighting-output object blink warn to honor blink-warn-enable.
* Fixed the blink warn logic for a non-zero percent value blink inhibit.
* Fixed the warn relinquish to actually relinquish.
* Refactored BACnetShedLevel encoding, decoding, and printing into separate file. Added unit testing.
* Added API to load control object for shed-level, start-time, duty-window, full-duty-baseline, and enable.
* Fixed bacapp sprintf for shed level and host-n-port found in scan build.
* Refactored the object-id to and from 32-bit value so channel-value could re-use the same API.
* Expanded the BACnetChannelValue coercion function to include all the coercions, no coercions, and invalid datatypes described in Table 12-63 of the Channel object. Expanded unit testing code coverage for BACnetChannelValue.
* Updated documentation for encode functions to accurately describe return values (0 on error instead of BACNET_STATUS_ERROR)
* Expanded property support, removed INPUT object types, added fallback encoding for non-coerced data types, and updated error handling in ReadProperty of present-value to check for 0 instead of BACNET_STATUS_ERROR.
* Expanded the validation tests and increased test code coverage.
* Enhanced string comparison functions and update indtext API usage
- Added library specific case-sensitive and case-insensitive string comparison functions that mimic strcmp.
- Updated indtext_by_string and indtext_by_istring to use the new comparison functions.
- Improved documentation for return values in indtext functions.
- Expanded test data in main.c for comprehensive testing when beginning of string matches another string.
* Added BACnetRecipient and BACnetAddressBinding encoding, decoding, ASCII conversion, comparison, and copy functions.
* Added library specific string manipulation utilities including strcmp, strncmp, stptok, and snprintf with offset functions.
* Added test/README about verification and validation testing.
* Refactored the BACnet/SC datalink initialization order by moving certificate file checks and hub connection registration to occur after datalink initialization
* Replaced stdlib rand() with platform-specific cryptographically secure random functions (RtlGenRandom for Windows, getrandom for Linux, arc4random_buf for BSD) to generate UUID and VMAC addresses, preventing duplicates that broke connections
* Enabled conditional debug output in BACnet/SC components when BUILD=debug is specified
* Added a new getter API function Timer_State_Change_Value_Get() to the timer object that returns state-change values by copying them to a caller-provided buffer, providing a safer alternative to the existing Timer_State_Change_Value() function which returns a direct pointer to internal data.
* Fixed compiler warning: ‘calloc’ sizes specified with ‘sizeof’ in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
* Fixed compile error found in pipeline build.
* Fixed pre-commit
* Added ListElement service callback for storing data.
* Added Audit Log and Time Value objects to basic device.
* Added Audit Log object to Makefile and CMake builds.
* Secured event and authentication decoding by removing deprecated functions.
* Added extended, discrete-value, double-out-of-range, signed-out-of-range, unsigned-out-of-range, change-of-characterstring, change-of-status-flags, change-of-reliability, and change-of-timer event notification encode, decode, and unit testing with #ifdef disabled by default.
