PROFILE
Jordan Rome
Worked extensively on the bpftrace/bpftrace repository, delivering core language and type system enhancements, parser modernization, and improved build stability. Over eight months, implemented a recursive-descent parser in C++ to replace flex/bison, overhauled the AST and type resolution pipeline, and introduced features like stack mode improvements and unnecessary type cast warnings. Addressed cross-distro build issues using CMake and refined session probe handling for safer kernel tracing. Enhanced documentation and test infrastructure, including mock BTF support for CI reliability. Focused on maintainability, performance, and user experience, leveraging skills in C++, BPF programming, and static analysis to drive robust, future-ready development.

Mar 1, 2026Summary for 2026-03 (bpftrace/bpftrace): Delivered a major TypeMap refactor that centralizes type information and improves compile-time reliability, progressed release readiness, enhanced LLVM 22 compatibility, and improved CI stability. Implemented immutable TypeMap pass state, propagated type resolution across tests, ResourceAnalyser, and Codegen passes, and removed TypeApplicator. Consolidated type handling by moving types into NamedParamInfo, migrating fold_literals, and moving subprog type checks to the type_checker, with SizedType removed from AST. Added 0.25 release prep, LLVM 22 readiness, and code-quality improvements (clang-tidy scoping). Addressed a broad set of bugs to improve correctness and stability, including Sizeof type resolution, verifier logging, strftime type, pointer handling, and privilege checks. These changes deliver business value through more reliable builds, easier maintenance, better debugging, and improved readiness for future performance enhancements.

Dec 1, 2024December 2024 monthly summary for bpftrace/bpftrace focusing on stability, accuracy, and documentation alignment. The primary initiative was to roll back the probe_inline feature to prevent fragmentation and ensure compatibility with existing user scripts, accompanied by updated documentation to reflect the actual feature set. This work reduces upgrade risk, prevents misuse of an experimental path, and improves maintainability for the project and users.
