compat.libuv.lua

-- compat.libuv — libuv 1.48.0, multi-platform async I/O library.
--
-- Shape A (C-source compat): the exact per-OS source sets from upstream's own
-- CMakeLists (`uv_sources` + the platform blocks), listed explicitly because
-- `src/unix/*.c` is NOT a safe glob — it holds one file per OS (aix.c, linux.c,
-- darwin.c, …) and compiling a foreign one fails. The 12 common files in
-- `src/*.c` are shared by every platform; each platform block adds its own.
-- `*/src` is on the include path for the package's own compile because
-- src/unix/internal.h does `#include "uv-common.h"` (lives in src/).
--
-- VERSION. 1.48.0 (2024-04) is the classic, widely-shipped release — it is
-- the libuv of the Ubuntu 24.04 LTS line and was the long-standing vcpkg
-- default before the 2025 releases; redis-plus-plus's async interface only
-- needs "libuv 1.x", so the battle-tested LTS-era pick is the right one.
--
-- Windows: link libs and defines mirror upstream CMakeLists verbatim
-- (psapi user32 advapi32 iphlpapi userenv ws2_32 dbghelp ole32 shell32).
--
-- No CN mirror yet: plain-string upstream URL (see compat.hiredis).
