Fix 1.8 release note about build-max-jobs
We set build-cores automatically, not build-max-jobs. (The commit
message for de4cdd0d47 also got this
wrong.)

unpack-channel.nix: fix 'mv' corner case
2017-02-27 13:12:35 +01:00
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!

This reverts commit 81c53fe8e5. This

platforms that previously did build:

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.:
