Description

A Bonity's C++ standard library — a header-only concurrency library implemented in C++26, covering parallel algorithms, thread-safe containers and lock-free data structures.

Get Started

• You can use git clone https://github.com/BoningtonChen/Bonostl to clone the repository.
• The Bonostl library headers are all .hpp headers, which means you can simply include them in your own projects.

Build

The project supports both CMake and xmake build systems. It requires a C++26 compiler and links libatomic for 16-byte atomics on GCC/Clang.

CMake

cmake -B build -G "MinGW Makefiles" -DCMAKE_CXX_COMPILER=g++
cmake --build build
./build/bonostl_benchmark.exe
ctest --test-dir build          # run the test suite

xmake

xmake f --toolchain=gcc
xmake
./build/windows/x64/release/bonostl_benchmark.exe
xmake run bonostl_tests         # run the test suite

Visual Studio

Both build systems work inside Visual Studio without changing the toolchain (MinGW GCC is still the compiler in both cases):

• CMake (Open Folder): File > Open > Folder... on the project root. Visual Studio reads CMakePresets.json and offers the mingw-debug / mingw-release presets for configure, build and test (CTest).
• xmake (solution): open vsxmake2026/Bonostl.slnx. The projects wrap xmake commands, so Build/Rebuild/Clean run xmake under the hood. Regenerate after changing xmake.lua:

  xmake project -k vsxmake2026 -m "debug,release"
  dotnet sln vsxmake2026/Bonostl.sln migrate   # upgrade to .slnx

  Set bonostl_benchmark (or bonostl_tests) as the startup project before running — the Bonostl target is a header-only library with no executable.

Testing

The test suite uses Catch2 v3 and covers:

• FIFO/LIFO ordering and empty states for all containers
• Concurrent producer/consumer invariants (element counts and value sums)
• Lock-free stack/queue stress tests with multiple threads
• Parallel algorithms verified against their std:: counterparts

Library Stuff

• bonostlpch(A dependency of a bunch of files included from C++ standard libraries)
• Containers
  • queue (single-threaded; use threadsafe_queue or lockfree_queue for concurrency)
  • threadsafe_stack
  • threadsafe_queue
  • blocking_queue (bounded, blocking push/pop for backpressure)
  • threadsafe_lookup_table
  • threadsafe_list
  • lockfree_stack
  • lockfree_queue
  • lockfree_list (Harris-Michael ordered set, hazard-pointer reclaimed)
  • concurrent_skip_list (lazy skip list; ordered set, epoch-reclaimed)
  • lockfree_hash_map (split-ordered list; incremental resize without rehashing)
• Algorithms
  • parallel_accumulate
  • parallel_find
  • parallel_for_each
  • parallel_partial_sum
  • parallel_quick_sort
  • parallel_transform
  • parallel_predicates (count_if, all_of, any_of, none_of)
  • parallel_scan (inclusive and exclusive prefix sums)
  • parallel_merge_sort (stable)
• Locks
  • spinlock_mutex
  • shared_spinlock (reader-writer spin lock; std::shared_lock compatible)
  • seqlock (read-optimistic; readers never block)
• Synchronization (educational; prefer the std equivalents in production)
  • counting_semaphore / binary_semaphore (cf. std::counting_semaphore, C++20)
  • latch (cf. std::latch, C++20)
  • barrier (cf. std::barrier, C++20)
• Utilities
  • hazard_ptr (hazard-pointer reclamation helpers for lock-free containers)
  • epoch_reclaim (epoch-based reclamation domain for whole-operation protection)
• Thread pool
  • function_wrapper (move-only type-erased task wrapper)
  • work_stealing_queue
  • thread_pool (work-stealing thread pool with per-thread local queues)

Note: pop-style operations return std::optional<T> instead of throwing or returning null pointers. threadsafe_lookup_table::value_for also returns std::optional<Value>.
