This is necessary because we have multiple SQLite databases (e.g. the
binary cache cache).

Support auto-configuration of build-max-jobs
"build-max-jobs" and the "-j" option can now be set to "auto" to use
the number of CPUs in the system. (Unlike build-cores, it doesn't use
0 to imply auto-configuration, because a) magic values are a bad idea
in general; b) 0 is a legitimate value used to disable local
building.)

Fixes #1198.

unpack-channel.nix: fix 'mv' corner case

Bjørn Forsman f72206b736 unpack-channel.nix: fix 'mv' corner case
unpack-channel.nix fails if the tarball contains a directory named the
same as the channel:

  mv: cannot move 'nixpkgs' to a subdirectory of itself, '.../nixpkgs'

This commit fixes that by not moving the directory if it already has the
correct name.

Fix nix-shell tests
The nix-shell fix in 668fef2e4f revealed
that we had some --pure tests that incorrectly depended on PATH from
config.nix's mkDerivation being overwritten by the caller's PATH.

nix-shell: Overwrite environment variables
Need to remember that std::map::insert() and emplace() don't overwrite
existing entries...

This fixes a regression relative to 1.11 that in particular triggers
in nested nix-shells.

Before:

  $ nativeBuildInputs=/foo nix-shell -p hello --run 'hello'
  build input /foo does not exist

After:

  $ nativeBuildInputs=/foo nix-shell -p hello --run 'hello'
  Hello, world!

Dan Peebles e7cb2847ab Explicitly model all settings and fail on unrecognized ones
Previously, the Settings class allowed other code to query for string
properties, which led to a proliferation of code all over the place making
up new options without any sort of central registry of valid options. This
commit pulls all those options back into the central Settings class and
removes the public get() methods, to discourage future abuses like that.

Furthermore, because we know the full set of options ahead of time, we
now fail loudly if someone enters an unrecognized option, thus preventing
subtle typos. With some template fun, we could probably also dump the full
set of options (with documentation, defaults, etc.) to the command line,
but I'm not doing that yet here.

Support netrc in <nix/fetchurl.nix>
This allows <nix/fetchurl.nix> to fetch private Git/Mercurial
repositories, e.g.

  import <nix/fetchurl.nix> {
    url = https://edolstra@bitbucket.org/edolstra/my-private-repo/get/80a14018daed.tar.bz2;
    sha256 = "1mgqzn7biqkq3hf2697b0jc4wabkqhmzq2srdymjfa6sb9zb6qs7";
  }

where /etc/nix/netrc contains:

  machine bitbucket.org
  login edolstra
  password blabla...

This works even when sandboxing is enabled.

To do: add unpacking support (i.e. fetchzip functionality).

Include "curl" in the User-Agent header
Some sites (e.g. BitBucket) give a helpful 401 error when trying to
download a private archive if the User-Agent contains "curl", but give
a redirect to a login page otherwise (so for instance
"nix-prefetch-url" will succeed but produce useless output).

Add support for s3:// URIs
This adds support for s3:// URIs in all places where Nix allows URIs,
e.g. in builtins.fetchurl, builtins.fetchTarball, <nix/fetchurl.nix>
and NIX_PATH. It allows fetching resources from private S3 buckets,
using credentials obtained from the standard places (i.e. AWS_*
environment variables, ~/.aws/credentials and the EC2 metadata
server). This may not be super-useful in general, but since we already
depend on aws-sdk-cpp, it's a cheap feature to add.

nix-daemon: Don't splice with len=SIZE_MAX
2017-02-13 14:33:18 +01:00
Tuomas Tynkkynen 649a81bcd6 nix-daemon: Don't splice with len=SIZE_MAX
Currently, 'nix-daemon --stdio' is always failing for me, due to the
splice call always failing with (on a 32-bit host):

splice(0, NULL, 3, NULL, 4294967295, SPLICE_F_MOVE) = -1 EINVAL (Invalid argument)

With a bit of ftracing (and luck) the problem seems to be that splice()
always fails with EINVAL if the len cast as ssize_t is negative:
http://lxr.free-electrons.com/source/fs/read_write.c?v=4.4#L384

So use SSIZE_MAX instead of SIZE_MAX.

Tuomas Tynkkynen 2cd468874f Include config.h implicitly with '-include config.h' in CFLAGS
Because config.h can #define things like _FILE_OFFSET_BITS=64 and not
every compilation unit includes config.h, we currently compile half of
Nix with _FILE_OFFSET_BITS=64 and other half with _FILE_OFFSET_BITS
unset. This causes major havoc with the Settings class on e.g. 32-bit ARM,
where different compilation units disagree with the struct layout.

E.g.:
