Will Dietz 30f89e0d65 Process nix.conf options in "new" nix commands, add test.
Without this (minor) change, the options set using "--option"
or read from nix.conf were parsed but not used.

Implement RemoteStore::queryMissing()
This provides a significant speedup, e.g. 64 s -> 12 s for

  nix-build --dry-run -I nixpkgs=channel:nixos-16.03 '<nixpkgs/nixos/tests/misc.nix>' -A test

on a cold local and CloudFront cache.

The alternative is to use lots of concurrent daemon connections but
that seems wasteful.

nix-daemon: Disable path info cache
This is useless because the client also caches path info, and can
cause problems for long-running clients like hydra-queue-runner
(i.e. it may return cached info about paths that have been
garbage-collected).

Sandbox: Fix /dev/ptmx on recent kernels
This fixes "No such file or directory" when opening /dev/ptmx
(e.g. http://hydra.nixos.org/build/51094249).

The reason appears to be some changes to /dev/ptmx / /dev/pts handling
between Linux 4.4 and 4.9. See
https://patchwork.kernel.org/patch/7832531/.

The fix is to go back to mounting a proper /dev/pts instance inside
the sandbox. Happily, this now works inside user namespaces, even for
unprivileged users. So

  NIX_REMOTE=local?root=/tmp/nix nix-build \
    '<nixpkgs/nixos/tests/misc.nix>' -A test

works for non-root users.

The downside is that the fix breaks sandbox builds on older kernels
(probably pre-4.6), since mounting a devpts fails inside user
namespaces for some reason I've never been able to figure out. Builds
on those systems will fail with

  error: while setting up the build environment: mounting /dev/pts: Invalid argument

Ah well.

Shea Levy 0bb8db257d Add exec primop behind allow-unsafe-native-code-during-evaluation.
Execute a given program with the (optional) given arguments as the
user running the evaluation, parsing stdout as an expression to be
evaluated.

There are many use cases for nix that would benefit from being able to
run arbitrary code during evaluation, including but not limited to:

* Automatic git fetching to get a sha256 from a git revision
* git rev-parse HEAD
* Automatic extraction of information from build specifications from
  other tools, particularly language-specific package managers like
  cabal or npm
* Secrets decryption (e.g. with nixops)
* Private repository fetching

Ideally, we would add this functionality in a more principled way to
nix, but in the mean time 'builtins.exec' can be used to get these
tasks done.

The primop is only available when the
'allow-unsafe-native-code-during-evaluation' nix option is true. That
flag also enables the 'importNative' primop, which is strictly more
powerful but less convenient (since it requires compiling a plugin
against the running version of nix).

Compress NAR listings using the "text-compression" method
So if "text-compression=br", the .ls file in S3 will get a
Content-Encoding of "br". Brotli appears to compress better than xz
for this kind of file and is natively supported by browsers.

S3BinaryCacheStore: Support compression of narinfo and log files
You can now set the store parameter "text-compression=br" to compress
textual files in the binary cache (i.e. narinfo and logs) using
Brotli. This sets the Content-Encoding header; the extension of
compressed files is unchanged.

You can separately specify the compression of log files using
"log-compression=br". This is useful when you don't want to compress
narinfo files for backward compatibility.
