From c10c61449f954702ae6d8092120321744acd82ff Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Thu, 4 Feb 2016 14:28:26 +0100 Subject: Eliminate the "store" global variable Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.) --- src/nix-instantiate/nix-instantiate.cc | 13 ++++++------- 1 file changed, 6 insertions(+), 7 deletions(-) (limited to 'src/nix-instantiate') diff --git a/src/nix-instantiate/nix-instantiate.cc b/src/nix-instantiate/nix-instantiate.cc index 13a145a3b..a20c5ce63 100644 --- a/src/nix-instantiate/nix-instantiate.cc +++ b/src/nix-instantiate/nix-instantiate.cc @@ -9,7 +9,6 @@ #include "util.hh" #include "store-api.hh" #include "common-opts.hh" -#include "misc.hh" #include #include @@ -33,7 +32,7 @@ static bool indirectRoot = false; enum OutputKind { okPlain, okXML, okJSON }; -void processExpr(EvalState & state, const Strings & attrPaths, +void processExpr(ref store, EvalState & state, const Strings & attrPaths, bool parseOnly, bool strict, Bindings & autoArgs, bool evalOnly, OutputKind output, bool location, Expr * e) { @@ -80,7 +79,7 @@ void processExpr(EvalState & state, const Strings & attrPaths, else { Path rootName = gcRoot; if (++rootNr > 1) rootName += "-" + std::to_string(rootNr); - drvPath = addPermRoot(*store, drvPath, rootName, indirectRoot); + drvPath = addPermRoot(store, drvPath, rootName, indirectRoot); } std::cout << format("%1%%2%\n") % drvPath % (outputName != "out" ?
