Dec 1, 2025December 2025 - Monthly summary for axosyslog: Overview: A focused sprint delivering core feature enhancements for address/transport formatting, along with substantial improvements to FilterX foundations, JSON parsing, memory accounting, and per-thread allocation. These changes increase reliability, performance, and scalability of the logging pipeline while enabling richer data formatting for downstream systems. Key features delivered: - gsockaddr: added support for GSA_ADDRESS_PORT formatting to format addresses with port context, improving observability and routing decisions (commit b047b51b5f3d544c75deaf68a6ed3b78daaace56). - logproto-text-server: introduced a nul-terminated transport, and integrated support for this mode in the text server, enabling multi-line logs to be delivered as single records with explicit separators (commits 3d5b31701c7918c3422721966b84de191a6518e3; 93ddf3fbe4e0f2a9125f7d5fbeb6f4ea40497530; light: add support for "nul-terminated" transport). - FilterX: implemented move semantics across expressions and data structures, including move(), move_key() for dict/object, enabling safer copy-on-write transformations across the stack (commits b86bffc82db7f776d19aa35750448a1ad175003b; 6c28a550bad80fc1994bf8936c941cc3530b8d10; 8b1f5771e4db9d04935fe81ca3b4b24be475639e; fb8bed41e69e8b80be5cc4708e08274f5daee921). - FilterX: internal refactors and utilities to extract common table/dict helpers and streamline operations, improving maintainability and future optimization (commits d715f3a194ad25e609b4afad3cc5a2a409a00347; 0409eaec526b84b511a562a0e86434d487bb6e60). - JSON parsing and JSON tooling: migrated to jsmn-based parsing with header-only options and per-thread token storage; introduced stock filterx_object_from_json() usage pattern and enhancements to JSON token handling (commits 3ba7a6d26f3a69da67c132a3239904bca0b3da5f; cede4f6b9241dd43dc543457d02ff01a9acd8840; 9536e8934d873da8aa09c4e5aac3c87f49e16ade). - Thread-local allocation: added a thread-specific FilterXObject allocator and integrated its use in the runtime to reduce contention and improve throughput under multi-threaded workloads (d130e3f94e34e905562c81c08f0bc1e97f016acc; 579e3a142c519f2487ed2d482a9e55f779e2ee0e). - Performance and formatting enhancements: introduced format_json-based dict key formatting to ensure consistent JSON representation of keys (commit 88fc54b18b016a9c5c732f5753ead92f11806c9e); enhanced string handling with new JSON escaping safeguards and flags to optimize runtime string processing (multiple commits in filterx/object-string and related modules). Major bugs fixed: - logproto-text-server: removed starting CR/LF/NUL and trailing control characters to prevent unwanted prefixes leaking into messages, stabilizing log ingestion (commit 47c88da744ffcf820e96cd76188a55c03241ac61). - LogMessage memory handling: fixed memory management by unref'ing message references in log_msg_free_queue_node to prevent leaks and use-after-free scenarios (commit 638f86b96e0adfa746161dc9eed6c022459d0407). - filterx: weakref/truncation optimization to free unused references at block exits, reducing memory footprint and improving performance in long-running pipelines (commit 2f6c5db47b20f8b52edae31c87ddceca611b3cff). - filterx: dictionary/object metrics optimization by avoiding redundant strdup() on every key/value, reducing CPU load in hot paths (commit d013eeae272eeeb28d73f7b4e167877e44853b84). - filterx: ensure filterx_dict_sized_new() allocates enough space to hold expected dict entries, avoiding mid-runtime resizes (commit 5f03a5c50402101e260afba779db14ba4812fb42). - NVTable usage in LogMessage: fixed memory consumption calculations to reflect actual allocated memory more accurately, avoiding overestimation and reducing memory pressure (commit 7fe586c75fb481a98d1032bc09ba3ec599d352b7). - Test and tooling stability: addressed spurious clang warning in test_stats_cluster_key_builder and stabilized test suite related to thread wakeup flakes (commit c6a0a909f998d1ea3ad61e8f35126a0d047b127a; 1ee373703c3e96b40cadb3bdf7205187fca24d2c). Impact and business value: - Increased observability and reliability: port-aware address formatting and robust nul-terminated transport improve log fidelity, routing, and diagnostics in production environments. - Performance and scalability: per-thread allocators, weakref/table refactors, and memory accounting fixes reduce contention, memory footprint, and latency in high-throughput scenarios. - Developer productivity: cleaner, more maintainable code with clearer ownership, reduced risk of memory leaks, and richer JSON handling support, enabling faster feature delivery and safer refactoring. Technologies and skills demonstrated: - C-level systems programming, memory management, and performance tuning across logging pipeline components. - Multithreading and per-thread resource management (thread-local allocators). - Advanced JSON parsing and encoding workflows, including jsmn integration and per-thread token storage. - Refactoring for safer copy-on-write semantics, object lifecycle integrity, and robust error propagation. - Feature-focused delivery with measurable impact on reliability and throughput.

Dec 1, 2024December 2024: Delivered substantial performance, reliability, and observability improvements across axosyslog with a strong focus on FilterX optimization, diagnostics, and maintainability. Key features delivered include: (1) FilterX core optimization and metrics enhancements: inlined core components, introduced optimize() across expression types, moved frequently used members to the front, and added richer optimization telemetry, enabling faster expressions and clearer perf signals; (2) HTTP diagnostic improvements: include HTTP response text in diagnostic messages to accelerate debugging; (3) Log protocol server improvements: public restart_with_state() and hardened restart behavior with buffered state; (4) Affile/poll readability enhancement: indicate immediate readability when not at EOF; (5) Build system and maintenance improvements: optional libunwind support, added news file, perf profiling support, and performance-oriented dev tooling updates. Major bugs fixed include: (1) HTTP batch-lines handling fixed when only batch-bytes() is set; (2) Logreader cleanup: remove unused immediate check; (3) CFG subsystem: safe line indexing to avoid crashes; (4) FilterX scope handling: prevent multiple moves of variables array; (5) Protobuf bytes truthiness fix. Overall impact: elevated runtime performance and startup reliability, improved debugging and observability, and a stronger developer experience through streamlined build/dev tooling and clearer metrics. Technologies/skills demonstrated: C/C++ performance optimization, inlining strategies, expression optimization framework, metrics instrumentation, perf profiling, build system enhancements, grammar/parsing improvements, and advanced observability techniques.
