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.
2015-05-21 nix-collect-garbage: Don't call nix-envEelco Dolstra2-1/+91
Also, make sure --delete-older-than doesn't delete the current generation.
2015-05-21 Move profiles.{cc,hh} to libstoreEelco Dolstra2-0/+210
2015-05-13 cygwin: explicitly include required c headersRok Garbas2-0/+2
2015-05-12 Don't try to map /bin/sh to a store path on non-LinuxShea Levy1-0/+2
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.
2015-03-25 addToStore(): Take explicit name argumentEelco Dolstra5-29/+29
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
2015-03-06 Fix typos: s/the the/the/Daniel Hahler1-1/+1
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.
2015-02-17 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.
2015-02-04 Require linux 3.13 or later for chrootShea Levy1-1/+6
Fixes #453
2015-01-18 Make inputs writeable in the sandbox (builds still can’t actually write ↵Daniel Peebles1-2/+7
due to user permissions)
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.
2015-01-12 Add basic Apple sandbox supportDaniel Peebles1-17/+169
2015-01-08 Doh^2Eelco Dolstra1-1/+1
2015-01-08 DohEelco Dolstra1-3/+3
2015-01-08 Set /nix/store permission to 1737Eelco Dolstra2-19/+6
I.e., not readable to the nixbld group. This improves purity a bit for non-chroot builds, because it prevents a builder from enumerating store paths (i.e. it can only access paths it knows about).
2015-01-06 Fix building on DarwinEelco Dolstra1-1/+4
Fixes #433.
2014-12-29 LocalStore initialization: Don't die if build-users-group doesn't existShea Levy1-11/+12

http://hydra.nixos.org/build/17862041
2014-12-12 Remove chatty messageEelco Dolstra1-2/+0
This broke building with "-vv", because the builder is not allowed to write to stderr at this point.
