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/libexpr/common-opts.hh | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/libexpr/common-opts.hh') diff --git a/src/libexpr/common-opts.hh b/src/libexpr/common-opts.hh index be0f40202430..0500b0a832a3 100644 --- a/src/libexpr/common-opts.hh +++ b/src/libexpr/common-opts.hh @@ -4,6 +4,8 @@ namespace nix { +class StoreAPI; + /* Some common option parsing between nix-env and nix-instantiate. */ bool parseAutoArgs(Strings::iterator & i, const Strings::iterator & argsEnd, std::map & res); -- cgit 1.4.1
