From 349fd3b11f320453ad8eeb3031621d0ffcaf078d Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Sat, 11 Jan 2014 16:55:04 +0100 Subject: guix-register: Support registration in the current store, without '--prefix'. * nix/guix-register/guix-register.cc (register_validity): Leave 'info.path' unmodified when PREFIX is empty. (main): Call 'settings.processEnvironment' early on. Leave 'settings.nixStore' unmodified when PREFIX is empty. --- nix/guix-register/guix-register.cc | 25 ++++++++++++++++--------- 1 file changed, 16 insertions(+), 9 deletions(-) (limited to 'nix') diff --git a/nix/guix-register/guix-register.cc b/nix/guix-register/guix-register.cc index 14478f6a13..324673f346 100644 --- a/nix/guix-register/guix-register.cc +++ b/nix/guix-register/guix-register.cc @@ -1,5 +1,5 @@ /* GNU Guix --- Functional package management for GNU - Copyright (C) 2013 Ludovic Courtès + Copyright (C) 2013, 2014 Ludovic Courtès Copyright (C) 2007, 2008, 2009, 2010, 2011, 2012, 2013 Eelco Dolstra @@ -133,10 +133,13 @@ register_validity (LocalStore *store, std::istream &input, if (info.path == "") break; - /* Rewrite the input to refer final name, as if we were in a chroot - under PREFIX. */ - std::string final_prefix (NIX_STORE_DIR "/"); - info.path = final_prefix + baseNameOf (info.path); + if (!prefix.empty ()) + { + /* Rewrite the input to refer to the final name, as if we were in a + chroot under PREFIX. */ + std::string final_prefix (NIX_STORE_DIR "/"); + info.path = final_prefix + baseNameOf (info.path); + } /* Keep its real path to canonicalize it and compute its hash. */ std::string real_path; @@ -165,6 +168,9 @@ register_validity (LocalStore *store, std::istream &input, int main (int argc, char *argv[]) { + /* Honor the environment variables, and initialize the settings. */ + settings.processEnvironment (); + try { argp_parse (&argp, argc, argv, 0, 0, 0); @@ -173,10 +179,11 @@ main (int argc, char *argv[]) 'settings.nixStore', 'settings.nixDBPath', etc. */ LocalStore store; - /* Under the --prefix tree, the final name of the store will be - NIX_STORE_DIR.
