v3.1.1

May 2, 2026 · GitHub ↗

Post-v3.1.0 hygiene release: packaging metadata, coverage scope, CI workflow polish, a test-coverage push, cross-platform fixes, and toolchain bumps. No public API changes.

Changed

  • gempba::create_custom_node now takes a std::shared_ptr<node_core> directly (no more wrapping at the call site)
  • wall_time reimplemented on top of std::chrono (replaces gettimeofday) — same observable values, monotonic clock semantics
  • gempba::log_and_throw marked [[noreturn]] so static analyzers and the compiler's flow analysis understand the call never returns
  • score: cleaned up the kind / to_raw / from_raw paths and added explicit unreachable markers
  • node_core_impl: lazy-init and result paths consolidated; redundant explicit destructor on node removed; excessive debug logging trimmed
  • Codebase-wide clang-tidy identifier-naming pass (private members and locals only — no public API renames)

Removed

  • Dead prune() overload in work_stealing_load_balancer
  • Unreachable defensive checks in get_root_level_pending_node

Fixed

  • gempba::utils::get_nb_set_bits signed-char overflow on MinGW
  • MSYS2/MinGW build: <windows.h> is now included before <psapi.h> so psapi.h sees the types it needs
  • centralized_utils.hpp: NOMINMAX redefinition guarded so headers that already define it don't trigger a warning
  • node.hpp: <stacktrace> inclusion gated on the __cpp_lib_stacktrace feature test, not just __has_include

Build

  • MSYS2 PKGBUILD sha256 updated to match the v3.1.0 source tarball
  • Codecov reporting now excludes examples/, tests/, and external/ so coverage numbers reflect only library code
  • New clang-tidy and clang-format identifier-naming and configuration rules so future changes can't reintroduce the patterns just cleaned up
  • Ubuntu CI bumped to GCC 14; <stacktrace> and stdc++exp linkage gated accordingly so older toolchains still build the library
  • macOS CI defaults to the macos-26 runner image
  • Self-hosted runners are now matched by label set (multiple labels combined) rather than a single label
  • MS-MPI runtime installed on the Windows CI runner so the multiprocessing test set actually runs
  • clang-format diagnostics surfaced with the colored summary; lint.sh diagnostics made readable on the terminal
  • Skip the publish-test-results job when the upstream build was cancelled
  • runs-on injected from vars.RUNNER_* repository variables so runner targets can change without editing each workflow
  • New full-coverage tests for the gempba facade, node_manager, quasi_horizontal_load_balancer, work_stealing_load_balancer, node_core_impl, centralized_utils, plus branch coverage for queue, utils, score, and node
  • Thread pool readiness ordering tightened in throw/discard tests so the send() race no longer deflakes them
  • Dropped flaky peak-vs-current RSS comparisons from the memory-usage tests
  • -Wunused warnings silenced on header-only helpers
