2015-03-25 Add fetchTarball builtinEelco Dolstra2-1/+120
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 https://github.com/NixOS/nixpkgs/archive/2766a4b44ee6eafae03a042801270c7f6b8ed32a.tar.gz) {}; This patch also adds a ‘fetchurl’ builtin that downloads but doesn't unpack its argument. Not sure if it's useful though.
2015-03-25 addToStore(): Take explicit name argumentEelco Dolstra8-35/+35
2015-03-24 Improve setting the default chroot dirsEelco Dolstra2-2/+7
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.
2015-03-24 Tighten permissions on chroot directoriesEelco Dolstra1-2/+12
2015-03-24 Don't rely on __noChroot for corepkgsEelco Dolstra1-2/+5
This doesn't work anymore if the "strict" chroot mode is enabled. Instead, add Nix's store path as a dependency. This ensures that its closure is present in the chroot.
2015-03-19 Disable scanning for interior pointersEelco Dolstra1-0/+2
This may remove the "Repeated allocation of very large block" warnings.
2015-03-19 Fix Boehm API violationEelco Dolstra4-38/+48
We were calling GC_INIT() after doing an allocation (in the baseEnv construction), which is not allowed.

2015-03-06 Improve error messageEelco Dolstra2-19/+25
2015-03-04 Add option to hide display of missing pathsEelco Dolstra1-1/+2
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
Make the default impure prefix include all of /System/Library
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?
2015-03-02 Allow local networking in the darwin sandbox to appease testsDan Peebles1-0/+3
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.
2015-02-23 Add restricted evaluation modeEelco Dolstra5-11/+50
If ‘--option restrict-eval true’ is given, the evaluator will throw an exception if an attempt is made to access any file outside of the Nix search path. This is primarily intended for Hydra, where we don't want people doing ‘builtins.readFile ~/.ssh/id_dsa’ or stuff like that.
2015-02-19 Merge branch 'tilde-paths' of https://github.com/shlevy/nixEelco Dolstra3-2/+6

2015-02-18 nix-store --generate-binary-cache-key: Write key to diskEelco Dolstra1-4/+8
This ensures proper permissions for the secret key.
2015-02-17 Use $<attr>Path instead of $<attr> for passAsFileEelco Dolstra1-1/+1
2015-02-17 Allow passing attributes via files instead of environment variablesEelco Dolstra1-4/+16
Closes #473.
2015-02-16 Use pivot_root in addition to chroot when possibleHarald van Dijk1-7/+28
chroot only changes the process root directory, not the mount namespace root directory, and it is well-known that any process with chroot capability can break out of a chroot "jail". By using pivot_root as well, and unmounting the original mount namespace root directory, breaking out becomes impossible. Non-root processes typically have no ability to use chroot() anyway, but they can gain that capability through the use of clone() or unshare(). For security reasons, these syscalls are limited in functionality when used inside a normal chroot environment. Using pivot_root() this way does allow those syscalls to be put to their full use.
2015-02-10 Make libsodium an optional dependencyEelco Dolstra1-0/+6
2015-02-10 Add base64 encoder/decoderEelco Dolstra3-8/+66

2015-02-04 Require linux 3.13 or later for chrootShea Levy1-1/+6
Fixes #453
2015-02-04 Use libsodium instead of OpenSSL for binary cache signingEelco Dolstra4-10/+53
Sodium's Ed25519 signatures are much shorter than OpenSSL's RSA signatures. Public keys are also much shorter, so they're now specified directly in the nix.conf option ‘binary-cache-public-keys’. The new command ‘nix-store --generate-binary-cache-key’ generates and prints a public and secret key.

$ nix-env -f ~/Dev/nixops/ -iA foo nix-env: src/libexpr/eval.hh:57: void nix::Bindings::push_back(const nix::Attr&): Assertion `size_ < capacity' failed. Aborted
2015-01-13 Allow using /bin and /usr/bin as impure prefixes on non-darwin by defaultShea Levy1-1/+1
These directories are generally world-readable anyway, and give us the two most common linux impurities (env and sh)
2015-01-13 SysError -> ErrorEelco Dolstra1-1/+1
2015-01-13 Don't resolve symlinks while checking __impureHostDepsEelco Dolstra1-2/+5
Since these come from untrusted users, we shouldn't do any I/O on them before we've checked that they're in an allowed prefix.

2015-01-09 Fix builtins.readDir on XFSEelco Dolstra1-1/+1
The DT_UNKNOWN fallback code was getting the type of the wrong path, causing readDir to report "directory" as the type of every file. Reported by deepfire on IRC.
