Large files within source tree causes build to run out of memory #358
Description
If the size of a file or a sufficient number of files in a nix-build exceeds the amount of memory available, Nix runs out of memory and gives up. For example, given this simple build:
{ stdenv, pkgs, ... } :
stdenv.mkDerivation rec {
name = "huge";
src = ./.;
buildInputs = [ ];
buildPhase =
''
md5sum huge.bin > md5.result
'';
installPhase =
''
mkdir $out
mv md5.result $out
'';
}
where huge.bin is a very huge file, nix will first warn:
warning: dumping very large path (> 256 MiB); this may run out of memory
before eventually running out of memory.
The above was tested with
nix-build (Nix) 1.8pre3834_9b146a5
