February 2026 monthly summary for traPtitech/traQ: Delivered Open Graph Protocol parser improvements (ogpparser) and core library refactors with notable performance optimizations. Reduced log noise in OGP fetch error handling, and improved maintainability by renaming packages (OGP to ogpparser; HMAC to hmacutil) and optimizing emoji CSS generation via Fprintf. These changes enhance social previews reliability, reduce debugging overhead, and set a clearer foundation for future feature work.

January 2026 monthly summary for traPtitech/traQ: Delivered security-focused enhancements to data fetch and Open Graph Protocol (OGP) integration, plus reliability improvements via logging and caching. Key features delivered: - Secure URL validation and SSRF prevention across data fetch and OGP operations, including DNS/IP validation post-resolution and reuse of validated IPs. Commits include: f18e0193b240a4c6a3eb435d0c94740f4c1a170f; cfa9c829cdb01b90c3a39912769adecda6dd8509; 9397295f1e277de84fee93f41423629a4b43605b; 24cedabef0bf10dd73630894a03bd172ac77f02e; ac802f422eabd49bd459e25f2f263418eb7c3444; 417940851f9a55df7eb1b5a9874959df9cd2eaca; 093b043a213ff4839f9f761abeb4e1bedbafe215. - OGP enhancements: logging for failures, parser error handling, and negative caching to improve resilience. Commits include: ac5d0e745e448d9efb39ac8451a4d2503f72108b; 04fefe1fbffb31e55c1fe334dfca718900a2430e; 9b243b47e51df3631aba581a65c658001bf8ca44. Major bugs fixed: - SSRF vulnerability and related data-fetch path issues in OGP handling (fix SSRF when fetching OGP). CI-related fixes were also applied to stabilize OGP workflows. Parser updates and error-name normalization addressed inconsistencies observed during builds and runtime. Overall impact and accomplishments: - Security: mitigated SSRF risks in external data fetch paths; reduced attack surface for Open Graph data. - Reliability: improved observability with targeted debug logs, robust error handling, and resilience via negative caching. - Performance: reduced repeated OGP fetches due to negative caching; faster issue diagnosis due to structured logging. - Business value: more trustworthy social previews, lower operational risk, and faster time-to-diagnose for OGP-related incidents. Technologies/skills demonstrated: - Go, Open Graph Protocol integration, DNS/IP validation, SSRF mitigation, logging and error handling, negative caching, and CI workflow improvements.
