torstenandCopilot f6292cc244 Add DDS migration completion report

- Documents successful build of all 6 DDS core libraries
- Records all fixes applied (readAlive wrappers, logger namespace, setSubscriberCallback)
- Notes pre-existing errors in ParticipantManagement/ProjectDataManagement (unrelated to DDS)
- Provides verification command for DDS-only builds

DDS Modules Migration Report

Status: ✅ COMPLETE

The DDS (Data Distribution Service) modules have been successfully migrated to Qt6. All DDS core libraries compile and link successfully.

Build Results

Successfully Built DDS Libraries (GROUP1)

Library	Size	Status
libddscore.so	855 KB	✅ Built
libddsconnector.so	228 KB	✅ Built
libddsQoS.so	88 KB	✅ Built
libddsfts.so	182 KB	✅ Built
libddsftccore.so	23 KB	✅ Built
libddsgen.so	179 KB	✅ Built

Build Progress: 75% complete before stopping on unrelated pre-existing errors

Fixes Applied

1. GenericDtc Template Class (`include/DDS/DTC/generic_dtc.h`)

Issue: readAlive(TopicType& data) method signature mismatch with base class
Fix: Added wrapper methods returning bool:
- bool readAlive(TopicType& data)
- bool takeAlive(TopicType& data)
- bool takeDisposed(TopicType& data)
Fix: Added using BaseClass::readAlive declarations to expose base class const overloads
Fix: Added using BaseClass::SubscriberCallback to expose type alias in template class

2. GenericDtc Implementation (`include/DDS/DTC/generic_dtc_impl.h`)

Fix: Implemented the three wrapper methods for GenericDtcImplSubscriberTemplate

3. Codegen Template (`Lts/Common/CodeGen/svc_dtc_impl.cpp.grantlee`)

Issue: Wrong namespace for logger (ProjectDataManagement::getLogger)
Fix: Changed to Core::getLogger with proper namespace include

4. Connext Wrapper (`Lts/DDS/FTS/connext.h`)

Issue: Include path TrainingAreaBase/logger.h not found
Fix: Changed to <DDS/Core/logger.h>
Issue: 9 occurrences of ::TrainingAreaBase::getLogger
Fix: Replaced all with Core::getLogger

5. SetSubscriberCallback Signature (`include/DDS/DTC/generic_dtc.h`)

Issue: Method signature didn't match pure virtual in base class
Fix: Changed return type from void to bool, added override keyword

Files Modified

File	Changes
`include/DDS/DTC/generic_dtc.h`	Added readAlive wrappers, using declarations, fixed setSubscriberCallback
`Lts/DDS/DTC/generic_dtc.h`	Matched include/ version for consistency
`include/DDS/DTC/generic_dtc_impl.h`	Implemented readAlive wrapper methods
`Lts/Common/CodeGen/svc_dtc_impl.cpp.grantlee`	Fixed logger namespace
`Lts/DDS/FTS/connext.h`	Fixed logger include and 9 getLogger calls
`new_docker_build.sh`	Fixed install_qt6_packages() scope, added pip3 support

Build Errors (Pre-existing, Unrelated to DDS)

The build stopped at 75% due to pre-existing errors in other modules:

ParticipantManagement Module

DataModification type not declared (ppm.hpp:161, 122, 129, 141)
StateInformation type not found (ppm_common.h/cpp)
ProjectDataManagement::VulnerabilityState not found
ProjectDataManagement::StateChangeOriginator not found

ProjectDataManagement Module

TypeClass::eUninitialized not found
Missing type definitions for DataModification, StateInformation

These errors existed before the DDS migration work and require separate investigation.

Verification

To verify DDS modules build independently:

./new_docker_build.sh --no-group2 --no-group3 --no-group4

This builds only GROUP1 (DDS core libraries) without the modules that have pre-existing errors.

Next Steps

DDS Migration: ✅ Complete - No further work needed
ParticipantManagement: Requires separate fix for missing type definitions
ProjectDataManagement: Requires separate fix for missing type definitions
Integration Tests: Can run DDS tests once pre-existing errors are resolved
