From bf1473f5e099b57b2363e97e680b36988a5de4f8 Mon Sep 17 00:00:00 2001 From: Vincent Bernat Date: Sun, 5 Aug 2018 18:17:27 +0200 Subject: haproxy: use getaddrinfo() on Linux (#44489) As per project's README: > Recent systems can resolve IPv6 host names using getaddrinfo(). This > primitive is not present in all libcs and does not work in all of > them either. Support in glibc was broken before 2.3. Some embedded > libs may not properly work either, thus, support is disabled by > default, meaning that some host names which only resolve as IPv6 > addresses will not resolve and configs might emit an error during > parsing. If you know that your OS libc has reliable support for > getaddrinfo(), you can add USE_GETADDRINFO=1 on the make command > line to enable it. This is the recommended option for most Linux > distro packagers since it's working fine on all recent mainstream > distros. It is automatically enabled on Solaris 8 and above, as it's > known to work. Without this option, it is not possible for HAProxy to solve IPv6-only names. This option is enabled in Debian builds without any notable adverse effect. --- pkgs/tools/networking/haproxy/default.nix | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/pkgs/tools/networking/haproxy/default.nix b/pkgs/tools/networking/haproxy/default.nix index aa19fdb04de..8f72976d7dc 100644 --- a/pkgs/tools/networking/haproxy/default.nix +++ b/pkgs/tools/networking/haproxy/default.nix @@ -39,7 +39,8 @@ stdenv.mkDerivation rec { "USE_LUA=yes" "LUA_LIB=${lua5_3}/lib" "LUA_INC=${lua5_3}/include" - ] ++ stdenv.lib.optional stdenv.isDarwin "CC=cc"; + ] ++ stdenv.lib.optional stdenv.isDarwin "CC=cc" + ++ stdenv.lib.optional stdenv.isLinux "USE_GETADDRINFO=1"; meta = { description = "Reliable, high performance TCP/HTTP load balancer"; -- cgit 1.4.1
