2015-09-03 Implement buildDerivation() via the daemonEelco Dolstra2-2/+11
2015-09-02 Filter build-chroot-dirs entries that conflict with derivation outputsEelco Dolstra1-4/+4
Fixes https://github.com/NixOS/nixpkgs/issues/9504. Note that this means we may have a non-functional /bin/sh in the chroot while rebuilding Bash or one of its dependencies. Ideally those packages don't rely on /bin/sh though.
2015-09-02 Remove unused variableEelco Dolstra1-5/+0
2015-08-24 Prevent .chroot from being GC'ed when using LocalStore::buildDerivation()Eelco Dolstra1-0/+4
Fixes #616.
2015-08-21 nix-collect-garbage: Revive --max-freedEelco Dolstra2-15/+4
Fixes #609.
2015-08-19 Remove unneeded HAVE_UNSHARE.Manolis Ragkousis1-1/+1
* src/libstore/build.cc (CHROOT_ENABLED): Remove HAVE_UNSHARE.
2015-08-04 Don't include <iostream> before config.hEelco Dolstra1-2/+2
This breaks the build on 32-bit systems. http://hydra.nixos.org/build/24373658
2015-08-03 Handle debug messages from runChild()Eelco Dolstra1-10/+16
Turns out that "nix-build -vvv" with chroots enabled has been broken for some time, because some debug message got interpreted as an error.
2015-07-26 Remove unnecessary parenthesesEelco Dolstra1-2/+2
2015-07-23 Fix fetchurl of executable fileEelco Dolstra1-1/+1
Pointed out by @cstrahan, thanks!
2015-07-21 Fix Darwin buildEelco Dolstra1-1/+4
Turns out getgrouplist() is not POSIX. http://hydra.nixos.org/build/23881243
2015-07-20 Make <nix/fetchurl.nix> a builtin builderEelco Dolstra6-4/+317
This ensures that 1) the derivation doesn't change when Nix changes; 2) the derivation closure doesn't contain Nix and its dependencies; 3) we don't have to rely on ugly chroot hacks.
2015-07-20 Provide more detailed info about build status to hydra-queue-runnerEelco Dolstra2-47/+75
In particular, hydra-queue-runner can now distinguish between remote build / substitution / already-valid. For instance, if a path already existed on the remote side, we don't want to store a log file.
2015-07-20 nix-copy-closure: Add -v flagEelco Dolstra1-1/+3
And make exportPath() less spammy by default.
2015-07-20 More cleanupEelco Dolstra3-115/+68
2015-07-17 OCD: foreach -> C++11 ranged forEelco Dolstra11-335/+331
2015-07-17 Allow remote builds without sending the derivation closureEelco Dolstra8-143/+300
Previously, to build a derivation remotely, we had to copy the entire closure of the .drv file to the remote machine, even though we only need the top-level derivation. This is very wasteful: the closure can contain thousands of store paths, and in some Hydra use cases, include source paths that are very large (e.g. Git/Mercurial checkouts). So now there is a new operation, StoreAPI::buildDerivation(), that performs a build from an in-memory representation of a derivation (BasicDerivation) rather than from a on-disk .drv file. The only files that need to be in the Nix store are the sources of the derivation (drv.inputSrcs), and the needed output paths of the dependencies (as described by drv.inputDrvs). "nix-store --serve" exposes this interface. Note that this is a privileged operation, because you can construct a derivation that builds any store path whatsoever. Fixing this will require changing the hashing scheme (i.e., the output paths should be computed from the other fields in BasicDerivation, allowing them to be verified without access to other derivations). However, this would be quite nice because it would allow .drv-free building (e.g. "nix-env -i" wouldn't have to write any .drv files to disk). Fixes #173.
2015-07-02 TypoEelco Dolstra1-1/+1
2015-07-01 Preserve supplementary groups of build usersLudovic Courtès1-2/+18
The following patch is an attempt to address this bug (see <http://bugs.gnu.org/18994>) by preserving the supplementary groups of build users in the build environment. In practice, I would expect that supplementary groups would contain only one or two groups: the build users group, and possibly the “kvm” group. [Changed &at(0) to data() and removed tabs - Eelco]
2015-06-30 GC: Handle ENOSPC creating/moving to the trash directoryEelco Dolstra1-8/+23
Issue #564.

2015-06-10 Export outputPaths functionEelco Dolstra3-11/+12
This is useful for the new hydra-queue-runner.
2015-06-09 Use std::vector::data()Eelco Dolstra1-5/+2
2015-06-04 Allow substitutes for builds that have preferLocalBuild setEelco Dolstra3-10/+18
Not substituting builds with "preferLocalBuild = true" was a bad idea, because it didn't take the cost of dependencies into account. For instance, if we can't substitute a fetchgit call, then we have to download/build git and all its dependencies. Partially reverts 5558652709f27e8a887580b77b93c705659d7a4b and adds a new derivation attribute "allowSubstitutes" to specify whether a derivation may be substituted.
2015-06-04 Chown files created for passAsFileEelco Dolstra1-2/+7
Nixpkgs' writeTextAsFile does this: mv "$textPath" "$n" Since $textPath was owned by root, if $textPath is on the same filesystem as $n, $n will be owned as root. As a result, the build result was rejected as having suspicious ownership. http://hydra.nixos.org/build/22836807
2015-06-02 Add a ‘verifyStore’ RPCLudovic Courtès4-1/+17
Hello! The patch below adds a ‘verifyStore’ RPC with the same signature as the current LocalStore::verifyStore method. Thanks, Ludo’. >From aef46c03ca77eb6344f4892672eb6d9d06432041 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ludovic=20Court=C3=A8s?= <ludo@gnu.org> Date: Mon, 1 Jun 2015 23:17:10 +0200 Subject: [PATCH] Add a 'verifyStore' remote procedure call.

2015-04-18 Add the pre-build hook.Shea Levy3-0/+41
This hook can be used to set system-specific per-derivation build settings that don't fit into the derivation model and are too complex or volatile to be hard-coded into nix. Currently, the pre-build hook can only add chroot dirs/files through the interface, but it also has full access to the chroot root. The specific use case for this is systems where the operating system ABI is more complex than just the kernel-support system calls. For example, on OS X there is a set of system-provided frameworks that can reliably be accessed by any program linked to them, no matter the version the program is running on. Unfortunately, those frameworks do not necessarily live in the same locations on each version of OS X, nor do their dependencies, and thus nix needs to know the specific version of OS X currently running in order to make those frameworks available. The pre-build hook is a perfect mechanism for doing just that.
2015-04-18 Revert "Add the pre-build hook."Shea Levy3-112/+0
Going to reimplement differently. This reverts commit 1e4a4a2e9fc382f47f58b448f3ee034cdd28218a.

2015-04-09 Implement a TTL on cached fetchurl/fetchTarball resultsEelco Dolstra2-0/+10
This is because we don't want to do HTTP requests on every evaluation, even though we can prevent a full redownload via the cached ETag. The default is one hour.
2015-04-07 Revert /nix/store permission back to 01775Eelco Dolstra2-2/+2
This broke NixOS VM tests. Mostly reverts 27b7b94923d2f207781b438bb7a57669bddf7d2b, 5ce50cd99e740d0d0f18c30327ae687be9356553, afa433e58c3fe6029660a43fdc2073c9d15b4210.
2015-04-02 Chroot builds: Provide world-readable /nix/storeEelco Dolstra1-1/+1
This was causing NixOS VM tests to fail mysteriously since 5ce50cd99e740d0d0f18c30327ae687be9356553. Nscd could (sometimes) no longer read /etc/hosts: open("/etc/hosts", O_RDONLY|O_CLOEXEC) = -1 EACCES (Permission denied) Probably there was some wacky interaction between the guest kernel and the 9pfs implementation in QEMU.

2015-03-24 Add the closure of store paths to the chrootEelco Dolstra1-0/+8
Thus, for example, to get /bin/sh in a chroot, you only need to specify /bin/sh=${pkgs.bash}/bin/sh in build-chroot-dirs. The dependencies of sh will be added automatically.

2015-03-04 Don't use vfork() before clone()Eelco Dolstra1-1/+3
I'm seeing hangs in Glibc's setxid_mark_thread() again. This is probably because the use of an intermediate process to make clone() safe from a multi-threaded program (see 524f89f1399724e596f61faba2c6861b1bb7b9c5) is defeated by the use of vfork(), since the intermediate process will have a copy of Glibc's threading data structures due to the vfork(). So use a regular fork() again.
2015-03-03 Merge branch 'allow-system-library' of git://github.com/copumpkin/nixShea Levy1-1/+1

2015-03-02 Make the default impure prefix (not actual allowed impurities!) include all ↵Dan Peebles1-1/+1
of /System/Library, since we also want PrivateFrameworks from there and (briefly) TextEncodings, and who knows what else. Yay infectious impurities?

2015-02-23 More graceful fallback for chroots on Linux < 2.13Eelco Dolstra1-6/+5
2015-02-23 Use chroots for all derivationsEelco Dolstra3-17/+35
If ‘build-use-chroot’ is set to ‘true’, fixed-output derivations are now also chrooted. However, unlike normal derivations, they don't get a private network namespace, so they can still access the network. Also, the use of the ‘__noChroot’ derivation attribute is no longer allowed. Setting ‘build-use-chroot’ to ‘relaxed’ gives the old behaviour.
