2020-01-12daemon: Account for deleted store files when deduplication is on.Ludovic Courtès
Previously, a store item that is a regular file would not be accounted for in the 'bytesFreed' value computed by 'deletePath' because its 'st_nlink' count would always be >= 2. This commit fixes that. * nix/libutil/util.hh (deletePath): Add optional 'linkThreshold' argument. * nix/libutil/util.cc (_deletePath): Add 'linkThreshold' argument and honor it. Pass it down in recursive call. (deletePath): Add 'linkThreshold' and honor it. * nix/libstore/gc.cc (LocalStore::deleteGarbage): Pass 'linkThreshold' argument to 'deletePath', with a value of 2 when PATH is a store item and deduplication is on.
