Nov 1, 2025November 2025: Delivered stability and capabilities in singnet/das through three focused changes: (1) correct and test-covered handling of duplicates in upsert_document, preventing errors and ensuring accurate counts; (2) new MorkDB query_for_targets to fetch target handles with unit tests for presence/absence; (3) memory-management improvements in HandleListMork with processing AtomDocument directly and a destructor to prevent leaks. These changes improve data integrity, query capability, and runtime efficiency, supported by targeted tests. Result: reduced error-prone paths, clearer metrics for operations, and enhanced maintainability.

Key features and improvements: - Distributed architecture enablement: added QueryEvolutionProxy params, ContextBrokerProxy, and DistributedAtomSpace params; enabled distributed networking with DistributedAtomSpace::join_network and ContextBroker abort handling. - Data path robustness: MorkDB add_link/delete_link, AtomDB upsert, not throwing on delete link, and MODULE restoration, with related integrity improvements. - Dynamic context capabilities: added das-evolution and das-create-context operations to support evolving contexts. - Developer experience: improved documentation, introduced a make run command, README polish, and expanded test coverage. - Stability enhancements: improved empty-value handling and processor loop, Redis context pool retry logic, and context/log fixes to reduce operational risk. Overall impact and accomplishments: - Enabled easier multi-node deployments and more resilient data operations, leading to faster onboarding and steadier runtime under load. - Strengthened platform reliability, reduced maintenance friction, and demonstrated a commitment to thorough testing and quality. Technologies/skills demonstrated: - Distributed systems design and proxy-based architecture (QueryEvolutionProxy, ContextBrokerProxy, DistributedAtomSpace) - Robust data modeling and transactional semantics (MorkDB/AtomDB upsert, link management, module restoration) - Dynamic context management (das-evolution, das-create-context) - Developer tooling and QA (documentation, make tooling, test coverage) - Operational reliability (retry logic, context handling, and logging fixes)

Sep 1, 2025September 2025 monthly summary for singnet/das focused on delivering core capabilities, stabilizing data-layer operations, and expanding integration patterns to improve reliability and business value. Highlights include new pattern support, performance optimizations, parser enhancements, and expanded integration with ContextBroker, while cleaning up the codebase and hardening critical data paths. Key features delivered: - RedisMongoDB::add_patterns(): introduced support for pattern additions, enabling dynamic data indexing use cases and faster pattern matching. - Use faster And hash_function(): switched to a more performant hash_function() implementation to reduce CPU usage and latency in hashing operations. - MettaParserActions and related tests: added commons::atoms::MettaParserActions with robust and/or test coverage to improve parsing reliability. - MorkDB improvements and MongoDB-only mode: enhanced query stability and introduced MongoDB-only mode for simplified deployments and reduced configuration complexity. - ContextBroker Integration Enhancements: added a ContextBroker processor and proxy, accompanying tests, and enforced AB endpoint requirements to ensure consistent integration behavior. - Remove attention_broker_setup() and associated tests: codebase cleanup to reduce maintenance overhead and potential sources of drift. - Skip flag for delete methods: added a skip flag to delete operations with tests to improve safety in destructive actions. Major bugs fixed: - Fixed MongodbDocument::get_size() and added unit test for MongodbDocumentGetSize to ensure correct size computation. - Copy all field at LinkSchema::operator=(other): ensured complete field copy semantics in assignment operator. - Restored LinkTemplate.cc after changes and reverted problematic updates to src/main/query_engine_main.cc where appropriate. - Initialize sum value: addressed an uninitialized variable by setting an initial sum. - Additional code review adjustments and master sync/conflict resolution to align with the main branch. Overall impact and accomplishments: - Improved system performance and stability, reducing runtime latency and CPU usage in core data paths. - Expanded integration capabilities with ContextBroker and MongoDB-only mode, enabling simpler, more reliable deployments. - Improved test coverage and code quality through targeted fixes, cleanup, and review-driven refinements. - Delivered measurable business value by enabling faster pattern ingestion, safer delete operations, and more robust data handling across repositories. Technologies/skills demonstrated: - C++, MongoDB, Redis, MorkDB, and ContextBroker integrations - Test-driven development (unit and integration tests) - Refactoring, code reviews, and Git-based release discipline - Performance optimization (hash function) and reliability hardening
