From 14bc3ce3d6d5745717fa19b8b43b5fdd117ff757 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Sat, 13 Jun 2009 16:30:58 +0000 Subject: * Canonicalise timestamps in the Nix store to 1 (1970-01-01 00:00:01 UTC) rather than 0 (00:00:00). 1 is a better choice because some programs use 0 as a special value. For instance, the Template Toolkit uses a timestamp of 0 to denote the non-existence of a file, so it barfs on files in the Nix store (see template-toolkit-nix-store.patch in Nixpkgs). Similarly, Maya 2008 fails to load script directories with a timestamp of 0 and can't be patched because it's closed source. This will also shut up those "implausibly old time stamp" GNU tar warnings. --- src/libstore/local-store.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/libstore/local-store.cc') diff --git a/src/libstore/local-store.cc b/src/libstore/local-store.cc index 51a32a3d1e5a..704bb1a06602 100644 --- a/src/libstore/local-store.cc +++ b/src/libstore/local-store.cc @@ -153,7 +153,7 @@ void canonicalisePathMetaData(const Path & path, bool recurse) if (st.st_mtime != 0) { struct utimbuf utimbuf; utimbuf.actime = st.st_atime; - utimbuf.modtime = 0; + utimbuf.modtime = 1; /* 1 second into the epoch */ if (utime(path.c_str(), &utimbuf) == -1) throw SysError(format("changing modification time of `%1%'") % path); } -- cgit 1.4.1
