From 4d9db420ffc9bd48da107a61c093b0d65d9d8db1 Mon Sep 17 00:00:00 2001 From: Daiderd Jordan Date: Sun, 12 Apr 2020 09:57:22 +0200 Subject: never use /var/folders for TMPDIR on darwin This doesn't just cause problems for nix-store --serve but also results in certain build failures. Builds that use unix domain sockets in their tests often fail because the /var/folders prefix already consumes more than half of the maximum length of socket paths. struct sockaddr_un { sa_family_t sun_family; /* AF_UNIX */ char sun_path[108]; /* Pathname */ }; --- src/libmain/shared.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/libmain') diff --git a/src/libmain/shared.cc b/src/libmain/shared.cc index d41e772e9..72ba717e5 100644 --- a/src/libmain/shared.cc +++ b/src/libmain/shared.cc @@ -155,7 +155,7 @@ void initNix() sshd).
