compat.c-ares.lua

-- compat.c-ares — c-ares 1.34.5, the asynchronous DNS resolver gRPC uses.
--
-- Shape A (C source compat) with ONE wrinkle: c-ares normally learns about its
-- host from a configure/CMake step that writes `ares_config.h`. That step is
-- replaced here by a frozen per-OS snapshot under `generated_files` — the same
-- "config snapshot + source list, no external build system" shape compat.ffmpeg
-- uses, and the same snapshots gRPC itself ships and builds with.
--
-- Two things the upstream RELEASE tarball already provides, so they are not
-- synthesized here: `include/ares_build.h` (generated by `make dist`, unlike
-- ares_config.h), and `src/lib/config-win32.h`.
--
-- Version follows upstream verbatim, and 1.34.5 is also gRPC 1.83.0's pin
-- (third_party/cares/cares submodule == tag v1.34.5), so the gRPC package can
-- depend on this one instead of vendoring a second copy.

        -- them precisely so the library can be built without running configure
        -- or CMake, which is what this package needs too.
        --
        -- THEY USED TO BE SELECTED BY THE OPERATING SYSTEM, and a configure
        -- snapshot describes a C ENVIRONMENT. Those were the same question
        -- until a C library began presenting POSIX on Windows: over openkal the
        -- target is still PE and still Win64, and `config_windows` then
        -- describes nothing that is there. Of the sixteen headers it declares
        -- absent, fifteen are present in that graph, and the first three
        -- diagnostics a build produced -- `windows.h` not found, then
        -- `gettimeofday` undeclared, then `struct hostent` incomplete -- were
        -- each one macro of the sixteen, with thirteen more behind them.
        --
        -- `_WIN32` AND `__APPLE__` ARE THE ENGINE'S ANSWER TO EXACTLY THIS
        -- QUESTION, so the selection needs no new key in this descriptor and no
        -- new axis in the engine. mcpp defines `_WIN32` for a Win32 environment
        -- and suppresses it for a POSIX-presenting one; the file asks the
        -- preprocessor which environment it is being compiled in, which is the
        -- question it was always answering.
        --
        -- Measured: x86_64-windows-gnu over openkal goes from `fails` to `runs`.
        -- Linux and macOS select the same snapshot they selected before, byte
        -- for byte, so neither reading moves.
        --
        -- `cflags`/`ldflags` stay per-OS below: a real Windows target still
        -- needs ws2_32, and a POSIX-presenting one asks for nothing in it.
