* Enable C++20 alongside C11 in the build
Add CXX to the project with C++20 (no extensions) and build C++ sources
with -Wextra -fno-exceptions -fno-rtti -fno-threadsafe-statics on top of
the existing warning flags. Give every toolchain a C++ compiler: the zig
Windows toolchain, the static macOS/Windows CI jobs, the static musl
image (clang++ plus libstdc++ headers) and the RPM spec.
* Add C++20 ownership and allocation core
Header-only primitives for the no-heap-after-startup design:
Result/Status, Region, ObjectPool with PoolPtr (std::unique_ptr with a
pool deleter), generation-checked Handle and asynchronous close support,
intrusive RefPtr, FixedBuffer, MonotonicArena, FixedHashMap and FixedLru,
IntrusiveList, and a bounded FixedHeap for third-party allocator hooks.
Unit tests cover each primitive (test_core_*). scripts/check_no_heap.py
rejects heap allocation in C++ sources under src/ and runs as a ctest.
clang-tidy now also analyses C++ sources and the core headers.
* Add heap allocation audit for relayed connections
alloc_counter is a preloadable malloc counter (glibc, macOS) that writes
a snapshot on SIGUSR2. measure_alloc.py warms ss-local and ss-server up,
snapshots both, relays more connections and reports allocations per
connection. It runs report-only as the alloc_audit_report ctest.
interop.peers() now yields the started processes.
* Document the C++20 port and allocation baseline
docs/cpp-core.md describes the language profile, the core primitives,
the phase plan and the measured C baseline (77-89 allocations per
connection in ss-server, 27-39 in ss-local). The compatibility contract
now keeps the C11 public header instead of a C11 code base. CLAUDE.md
drops stale libev, submodule and gnu99 references.
* Fix CI for the C++ core: libstdc++ headers, static unwinder, newer clang
- docker/static: Alpine's libstdc++ headers come with g++, and the C++
tests' static libstdc++ needs an unwinder that compiler-rt lacks; add
g++ and llvm-libunwind.
- FixedBuffer: drop the unused kCapacity (clang-tidy 18 reports it as a
dynamically initialized header static).
- ss-server on Windows: manager_addr was only read in POSIX-only code,
which newer clang rejects (-Wunused-but-set-global); say that the
option is ignored there.
* CI: allow running the test and build workflows by hand
Stacked PRs target their parent branch, which these workflows do not
trigger on; workflow_dispatch lets each layer run the full matrix.
* CI: let clang-tidy ignore GCC-only warning flags
The compile database comes from a GCC build, whose flags (for example
-Wno-class-memaccess) clang-tidy does not know and reports as errors.
Document the shadowsocks-libev history and shadowsocks-c rename, and recommend Docker installation with mounted configuration and TCP/UDP port mappings.
Add native AMD64/ARM64 builds of the unprivileged static runtime image, real container relay and shutdown tests, and GHCR publication after both architecture checks pass. All 24 build/test checks pass at reviewed head 3f3f6bf8e01e5614821d1e15fda3ad8f07812902; publication is intentionally skipped on pull requests.
Rename the project to shadowsocks-c while retaining ss-* commands, the embedding ABI, and legacy library/package lookup compatibility.
Replace libev with bundled libuv for IOCP/kqueue event backends, expand asynchronous runtime DNS coverage, and add actionlint/Ruff with strict clang-tidy failure handling. Validate native platforms, static builds, packaging, interoperability, sanitizers, and canonical/legacy consumers.
All 22 hosted checks pass at reviewed head a8493250eb.
Bundle pinned offline dependencies, remove libcork/libipset and submodule requirements, and add portable runtime helpers with relocatable static/shared library installations.
Add Clang static build validation for Linux/musl, macOS and Windows, real TCP/UDP and SIP003 interoperability coverage, and recorded performance tradeoffs. All 21 hosted checks pass at the reviewed PR head 8d504e6218.
