From c9f51e87057652db0013289a95deffba495b35e7 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Thu, 17 Sep 2020 10:42:51 +0200 Subject: [PATCH] Remove corepkgs/config.nix This isn't used anywhere except in the configure script of the Perl bindings. I've changed the latter to use the C++ API's Settings object at runtime. --- .gitignore | 9 ------ corepkgs/config.nix.in | 13 --------- corepkgs/local.mk | 4 +-- perl/configure.ac | 13 --------- perl/lib/Nix/Config.pm.in | 10 ++----- perl/lib/Nix/Store.pm | 60 ++------------------------------------- perl/lib/Nix/Store.xs | 10 +++++++ tests/recursive.sh | 6 ++-- 8 files changed, 19 insertions(+), 106 deletions(-) delete mode 100644 corepkgs/config.nix.in diff --git a/.gitignore b/.gitignore index 3f81f8ef5..4711fa7fa 100644 --- a/.gitignore +++ b/.gitignore @@ -12,15 +12,6 @@ perl/Makefile.config /svn-revision /libtool -/corepkgs/config.nix - -# /corepkgs/channels/ -/corepkgs/channels/unpack.sh - -# /corepkgs/nar/ -/corepkgs/nar/nar.sh -/corepkgs/nar/unnar.sh - # /doc/manual/ /doc/manual/*.1 /doc/manual/*.5 diff --git a/corepkgs/config.nix.in b/corepkgs/config.nix.in deleted file mode 100644 index cb9945944..000000000 --- a/corepkgs/config.nix.in +++ /dev/null @@ -1,13 +0,0 @@ -# FIXME: remove this file? -let - fromEnv = var: def: - let val = builtins.getEnv var; in - if val != "" then val else def; -in rec { - nixBinDir = fromEnv "NIX_BIN_DIR" "@bindir@"; - nixPrefix = "@prefix@"; - nixLibexecDir = fromEnv "NIX_LIBEXEC_DIR" "@libexecdir@"; - nixLocalstateDir = "@localstatedir@"; - nixSysconfDir = "@sysconfdir@"; - nixStoreDir = fromEnv "NIX_STORE_DIR" "@storedir@"; -} diff --git a/corepkgs/local.mk b/corepkgs/local.mk index 1546b4ef3..0bc91cfab 100644 --- a/corepkgs/local.mk +++ b/corepkgs/local.mk @@ -1,6 +1,4 @@ corepkgs_FILES = \ fetchurl.nix -$(foreach file,config.nix $(corepkgs_FILES),$(eval $(call install-data-in,$(d)/$(file),$(datadir)/nix/corepkgs))) - -template-files += $(d)/config.nix +$(foreach file,$(corepkgs_FILES),$(eval $(call install-data-in,$(d)/$(file),$(datadir)/nix/corepkgs))) diff --git a/perl/configure.ac b/perl/configure.ac index c3769e142..255744afd 100644 --- a/perl/configure.ac +++ b/perl/configure.ac @@ -70,19 +70,6 @@ PKG_CHECK_MODULES([NIX], [nix-store]) NEED_PROG([NIX], [nix]) -# Get nix configure values -export NIX_REMOTE=daemon -nixbindir=$("$NIX" --experimental-features nix-command eval --raw -f '' nixBinDir) -nixlibexecdir=$("$NIX" --experimental-features nix-command eval --raw -f '' nixLibexecDir) -nixlocalstatedir=$("$NIX" --experimental-features nix-command eval --raw -f '' nixLocalstateDir) -nixsysconfdir=$("$NIX" --experimental-features nix-command eval --raw -f '' nixSysconfDir) -nixstoredir=$("$NIX" --experimental-features nix-command eval --raw -f '' nixStoreDir) -AC_SUBST(nixbindir) -AC_SUBST(nixlibexecdir) -AC_SUBST(nixlocalstatedir) -AC_SUBST(nixsysconfdir) -AC_SUBST(nixstoredir) - # Expand all variables in config.status. test "$prefix" = NONE && prefix=$ac_default_prefix test "$exec_prefix" = NONE && exec_prefix='${prefix}' diff --git a/perl/lib/Nix/Config.pm.in b/perl/lib/Nix/Config.pm.in index bc1749e60..f7c6f2484 100644 --- a/perl/lib/Nix/Config.pm.in +++ b/perl/lib/Nix/Config.pm.in @@ -4,14 +4,8 @@ use MIME::Base64; $version = "@PACKAGE_VERSION@"; -$binDir = $ENV{"NIX_BIN_DIR"} || "@nixbindir@"; -$libexecDir = $ENV{"NIX_LIBEXEC_DIR"} || "@nixlibexecdir@"; -$stateDir = $ENV{"NIX_STATE_DIR"} || "@nixlocalstatedir@/nix"; -$logDir = $ENV{"NIX_LOG_DIR"} || "@nixlocalstatedir@/log/nix"; -$confDir = $ENV{"NIX_CONF_DIR"} || "@nixsysconfdir@/nix"; -$storeDir = $ENV{"NIX_STORE_DIR"} || "@nixstoredir@"; - -$useBindings = 1; +$binDir = Nix::Store::getBinDir; +$storeDir = Nix::Store::getStoreDir; %config = (); diff --git a/perl/lib/Nix/Store.pm b/perl/lib/Nix/Store.pm index d226264d4..179f1dc90 100644 --- a/perl/lib/Nix/Store.pm +++ b/perl/lib/Nix/Store.pm @@ -2,7 +2,6 @@ package Nix::Store; use strict; use warnings; -use Nix::Config; require Exporter; @@ -22,6 +21,7 @@ our @EXPORT = qw( addToStore makeFixedOutputPath derivationFromPath addTempRoot + getBinDir getStoreDir ); our $VERSION = '0.15'; @@ -34,62 +34,8 @@ sub backtick { return $res; } -if ($Nix::Config::useBindings) { - require XSLoader; - XSLoader::load('Nix::Store', $VERSION); -} else { - - # Provide slow fallbacks of some functions on platforms that don't - # support the Perl bindings. - - use File::Temp; - use Fcntl qw/F_SETFD/; - - *hashFile = sub { - my ($algo, $base32, $path) = @_; - my $res = backtick("$Nix::Config::binDir/nix-hash", "--flat", $path, "--type", $algo, $base32 ?
