2015-05-19Merge branch 'nix'....* daemon.am (AM_CXXFLAGS): Change -std=c++0x to -std=c++11. (libstore_a_CPPFLAGS): Add -DDEFAULT_CHROOT_DIRS. (parse_opt): Use 'settings.get' instead of 'settings.dirsInChroot'. (main): Likewise. * tests/guix-archive.sh: Don't grep for the "importing ..." message since it is no longer produced. The nix/ part is a squashed commit of the following: commit 3bfa70b7963e12be346900e64ae45fa019850675 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Wed Dec 10 13:53:04 2014 +0100 Don't wait for PID -1 The pid field can be -1 if forking the substituter process failed. commit 5241aec531e9c9a4b2dd5e5b6ee3f07ff049d9a5 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Mon Nov 24 16:48:04 2014 +0100 Build derivations in a more predictable order Derivations are now built in order of derivation name, so a package named "aardvark" is built before "baboon".

In particular, it was preventing the deletion of the temproot file for each worker process. It may also have been responsible for the excessive WAL growth on Hydra (due to the SQLite database not being closed properly).

For instance, the existence of the file /nix/var/nix/gcroots/per-user/eelco/hydra-roots/wzc3cy1wwwd6d0dgxpa77ijr1yp50s6v-libxml2-2.7.7 would cause /nix/store/wzc3cy1wwwd6d0dgxpa77ijr1yp50s6v-libxml2-2.7.7 to be a root. This is useful because it involves less I/O (no need for a readlink() call) and takes up less disk space (the symlink target typically takes up a full disk block, while directory entries are packed more efficiently). This is particularly important for hydra.nixos.org, which has hundreds of thousands of roots, and where reading the roots can take 25 minutes. commit 4ab4b0c109734bd6e265ca5f1b6415c31c03ab11 Author:

However, HFS+ is usually case-insensitive, so if there are directories with file names that differ only in case, then importing will fail. The solution is to add a suffix ("~nix~case~hack~<integer>") to colliding files. For instance, if we have a directory containing xt_CONNMARK.h and xt_connmark.h, then the latter will be renamed to "xt_connmark.h~nix~case~hack~1". If a store path is dumped as a NAR, the suffixes are removed. Thus, importing and exporting via a case-insensitive Nix store is round-tripping. So when NixOps calls nix-copy-closure to copy the path to a Linux machine, you get the original file names back. Closes #119. commit bb65460feb265be4d938c7dc724a76ef41a8bfaf Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Wed Jul 16 11:19:12 2014 +0200 Make dev-shell script work on Darwin commit de8be7c3e06b52c313e0b452b641ad5f90dca2fe Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Wed Jul 16 11:16:54 2014 +0200 Install systemd and Upstart stuff only on Linux commit 048be62484537633e2523dd4d200619649ff860d Author: Shea Levy <shea@shealevy.com> Date: Wed Jul 16 01:11:24 2014 -0400 Pass *_proxy vars to bootstrap fetchurl commit a2c85b2ef85a34bf8e5238c315a4ca73606f5ae6 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Wed Jul 16 11:09:01 2014 +0200 Manual: Typo commit 5bcb98271103c6c2ca3b993d8b1b0eb9eadcbc1c Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Mon Jul 14 12:39:33 2014 +0200 Remove cruft commit fa13d3f4f3d8fb6dc3e3fc87ac5a2e26d8b32d84 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Mon Jul 14 12:19:27 2014 +0200 build-remote.pl: Fix building multiple output derivations We were importing paths without sorting them topologically, leading to "path is not valid" errors.

It also makes it more or less secure to connect directly to the root account on the build machine, using a forced command (e.g. ‘command="nix-store --serve --write"’). This bypasses the Nix daemon and is therefore more efficient. Also, don't call nix-store to import the output paths. commit b8f24f253527e1cb071785c3b2d677ed2f734ab1 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Fri Jul 11 14:27:17 2014 +0200 Fix closure size display commit e196eecbe6552d5afed89ad480544c90cf959922 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Fri Jul 11 13:55:06 2014 +0200 Allow $NIX_BUILD_HOOK to be relative to Nix libexec directory commit d0eb970fb4d3b5c347506b77f9657fc5eb6229e2 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 10 21:48:21 2014 +0200 Fix broken Pid constructor commit edbfe2232e275a9e6c10cd8eb4dc36ca992af084 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 10 21:30:22 2014 +0200 Replace message "importing path <...>" with "exporting path <...>" This causes nix-copy-closure to show what it's doing before rather than after. commit 42d91b079c5d0b468663511e7b2a8e2f4048c475 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 10 21:14:34 2014 +0200 Fix use of sysread commit 7bb632b02464febd8806ef4bd3fa0ac107f52650 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 10 20:43:04 2014 +0200 nix-copy-closure -s: Do substitutions via ‘nix-store --serve’ This means we no longer need an SSH master connection, since we only execute a single command on the remote host. commit 7c3a5090bff4e9cfe70f1d89619563b55af13d89 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 10 17:44:18 2014 +0200 nix-copy-closure: Fix --dry-run commit 43b64f503844a66c344780a11289678a001572db Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 10 17:32:21 2014 +0200 Remove tabs commit 8e9140cfdef9dbd1eb61e4c75c91d452ab5e4a74 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 10 16:50:51 2014 +0200 Refactoring: Move all fork handling into a higher-order function C++11 lambdas ftw. commit 1114c7bd57bcab16255d5db5e6f66ae8dece7b1e Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 10 14:15:12 2014 +0200 nix-copy-closure: Restore compression and the progress viewer commit 7911e4c27a0020a61ace13cfdc44de4af02f315e Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Mon Jun 23 09:15:35 2014 -0400 Remove maybeVfork commit 04170d06bf7d17f882c01d3ab98885e0f3e46d2f Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 10 11:51:22 2014 +0200 nix-copy-closure: Fix race condition There is a long-standing race condition when copying a closure to a remote machine, particularly affecting build-remote.pl: the client first asks the remote machine which paths it already has, then copies over the missing paths. If the garbage collector kicks in on the remote machine between the first and second step, the already-present paths may be deleted. The missing paths may then refer to deleted paths, causing nix-copy-closure to fail. The client now performs both steps using a single remote Nix call (using ‘nix-store --serve’), locking all paths in the closure while querying. I changed the --serve protocol a bit (getting rid of QueryCommand), so this breaks the SSH substituter from older versions. But it was marked experimental anyway. Fixes #141. commit 2c3a8f787ba9da49feafdec4022534184e0a96a3 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 10 11:46:01 2014 +0200 Fix security hole in ‘nix-store --serve’ Since it didn't check that the path received from the client is a store path, the client could dump any path in the file system. commit 66dbc0fdeebf509c5d919e9c12b2645136d6deeb Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 10 01:50:29 2014 +0200 Add a test for the SSH substituter commit 0e5d0c15430cf82861a1ae213cbccff065f71107 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Wed Jul 9 12:14:40 2014 +0200 Fix compilation error on some versions of GCC src/libexpr/primops.cc:42:8: error: looser throw specifier for 'virtual nix::InvalidPathError::~InvalidPathError()' src/libexpr/nixexpr.hh:12:1: error: overriding 'virtual nix::EvalError::~EvalError() noexcept (true)' http://hydra.nixos.org/build/123857
