2015-07-17 Allow remote builds without sending the derivation closureEelco Dolstra12-154/+372
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.

2015-07-01 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.

2015-06-17 Support URLs in $NIX_PATHEelco Dolstra3-1/+32
This didn't work (despite claims in the manual), because the colon in "http://" was parsed as a element separator. So handle "://" specially.

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

Hello! The patch below adds a ‘verifyStore’ RPC with the same signature as the current LocalStore::verifyStore method.

2015-05-22 Fix import-from-derivation in restricted eval modeEelco Dolstra1-0/+7
This relaxes restricted mode to allow access to anything in the store. In the future, it would be better to allow access to only paths that have been constructed in the current evaluation (so a hard-coded /nix/store/blabla in a Nix expression would still be rejected). However, note that reading /nix/store itself is still rejected, so you can't use this so get access to things you don't know about.

For instance, you can install Firefox from a specific Nixpkgs revision like this: $ nix-env -f https://github.com/NixOS/nixpkgs/archive/63def04891a0abc328b1b0b3a78ec02c58f48583.tar.gz -iA firefox Or build a package from the latest nixpkgs-unstable channel: $ nix-build https://nixos.org/channels/nixpkgs-unstable/nixexprs.tar.xz -A hello
2015-05-06 nix-collect-garbage: Fix deleting old generationsWilliam A. Kennington III1-1/+1
The call to nix-env expects a string which represents how old the derivations are or just "old" which means any generations other than the current one in use. Currently nix-collect-garbage passes an empty string to nix-env when using the -d option. This patch corrects the call to nix-env such that it follows the old behavior.
2015-05-05 Allow URLs in the Nix search pathEelco Dolstra6-99/+123
E.g. to install "hello" from the latest Nixpkgs: $ nix-build '<nixpkgs>' -A hello -I nixpkgs=https://nixos.org/channels/nixpkgs-unstable/nixexprs.tar.xz Or to install a specific version of NixOS: $ nixos-rebuild switch -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/63def04891a0abc328b1b0b3a78ec02c58f48583.tar.gz

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.
