From 48cea0d01ef48733ab38a73a20611f63aeb1b5cc Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Tue, 3 Jan 2012 00:16:29 +0000 Subject: [PATCH] * Refactoring: Get rid of a few subdirectories in corepkgs/, and some other simplifications. * Use to locate the corepkgs. This allows them to be overriden through $NIX_PATH. * Use bash's pipefail option in the NAR builder so that we don't need to create a temporary file. --- corepkgs/Makefile.am | 12 +++++++- .../{buildenv/default.nix => buildenv.nix} | 7 +++-- .../{buildenv/builder.pl.in => buildenv.pl} | 2 -- corepkgs/buildenv/Makefile.am | 11 ------- corepkgs/nar.nix | 30 +++++++++++++++++++ corepkgs/nar/Makefile.am | 11 ------- corepkgs/nar/nar.nix | 7 ----- corepkgs/nar/nar.sh.in | 12 -------- scripts/nix-push.in | 5 +--- src/nix-env/user-env.cc | 2 +- tests/common.sh.in | 7 +---- tests/init.sh | 24 --------------- tests/lang.sh | 2 +- tests/lang/eval-okay-search-path.nix | 2 +- tests/user-envs.sh | 2 +- 15 files changed, 52 insertions(+), 84 deletions(-) rename corepkgs/{buildenv/default.nix => buildenv.nix} (81%) rename corepkgs/{buildenv/builder.pl.in => buildenv.pl} (99%) mode change 100755 => 100644 delete mode 100644 corepkgs/buildenv/Makefile.am create mode 100644 corepkgs/nar.nix delete mode 100644 corepkgs/nar/Makefile.am delete mode 100644 corepkgs/nar/nar.nix delete mode 100644 corepkgs/nar/nar.sh.in diff --git a/corepkgs/Makefile.am b/corepkgs/Makefile.am index b303a30eba..7f43a700e7 100644 --- a/corepkgs/Makefile.am +++ b/corepkgs/Makefile.am @@ -1 +1,11 @@ -SUBDIRS = nar buildenv channels +SUBDIRS = channels + +all-local: config.nix + +install-exec-local: + $(INSTALL) -d $(DESTDIR)$(datadir)/nix/corepkgs + $(INSTALL_DATA) config.nix $(srcdir)/nar.nix $(srcdir)/buildenv.nix $(srcdir)/buildenv.pl $(DESTDIR)$(datadir)/nix/corepkgs + +include ../substitute.mk + +EXTRA_DIST = config.nix.in nar.nix buildenv.nix buildenv.pl diff --git a/corepkgs/buildenv/default.nix b/corepkgs/buildenv.nix similarity index 81% rename from corepkgs/buildenv/default.nix rename to corepkgs/buildenv.nix index d76f527409..6e2bee10b1 100644 --- a/corepkgs/buildenv/default.nix +++ b/corepkgs/buildenv.nix @@ -1,9 +1,12 @@ -{system, derivations, manifest}: +with import ; + +{ system, derivations, manifest }: derivation { name = "user-environment"; system = system; - builder = ./builder.pl; + builder = perl; + args = [ "-w" ./buildenv.pl ]; manifest = manifest; diff --git a/corepkgs/buildenv/builder.pl.in b/corepkgs/buildenv.pl old mode 100755 new mode 100644 similarity index 99% rename from corepkgs/buildenv/builder.pl.in rename to corepkgs/buildenv.pl index 86abe0ca19..52a703c066 --- a/corepkgs/buildenv/builder.pl.in +++ b/corepkgs/buildenv.pl @@ -1,5 +1,3 @@ -#!
