Eelco Dolstra 920f5fd4dd Fix import-from-derivation in restricted eval mode
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.

Christian Theune 3d83188702 Enable lazy/sparse allocation of generation symlinks: avoid creating
new generations if a generation already exists.

Alternatively or additionally I propose a mode where only the *last* generation will be sparse.

Eelco Dolstra 6519f06f39 nix-env/nix-instantiate/nix-build: Support URIs
For instance, you can install Firefox from a specific Nixpkgs revision
like this:

  $ nix-env -f 63def04891.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

William A. Kennington III 0705d04dfa nix-collect-garbage: Fix deleting old generations
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.
2015-05-06 11:02:36 +02:00
Eelco Dolstra 9451ef3731 Allow URLs in the Nix search path
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=63def04891.tar.gz

tests: Fix wrong channel name in nix-channel.sh.
The $channelName variable passed to the channel builder is the last
portion of the URL and while that works in the previous test for
channels prior to #519, it doesn't work if the last portion is
nixexprs.tar.bz2.

Shea Levy 4d652875bd Add the pre-build hook.
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.

Shea Levy fd6774e285 Revert "Add the pre-build hook."
Going to reimplement differently.

Eelco Dolstra c1f04fae35 Implement a TTL on cached fetchurl/fetchTarball results
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.

Eelco Dolstra afa433e58c Chroot builds: Provide world-readable /nix/store
This was causing NixOS VM tests to fail mysteriously since
5ce50cd99e. 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.

Eelco Dolstra 000b5a000f Add fetchTarball builtin
This function downloads and unpacks the given URL at evaluation
time. This is primarily intended to make it easier to deal with Nix
expressions that have external dependencies. For instance, to fetch
Nixpkgs 14.12:

  with import (fetchTarball https://github.com/NixOS/nixpkgs-channels/archive/nixos-14.12.tar.gz) {};

Or to fetch a specific revision:

  with import (fetchTarball 2766a4b44e.tar.gz) {};

This patch also adds a ‘fetchurl’ builtin that downloads but doesn't
unpack its argument. Not sure if it's useful though.

Eelco Dolstra fd89f97be9 Add the closure of store paths to the chroot
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.
