Disable EvalCache in impure mode 2019-06-07 22:38:39 +02:00

6644b6099b
Add flake evaluation cache 
This exploits the hermetic nature of flake evaluation to speed up
repeated evaluations of a flake output attribute.

For example (doing 'nix build' on an already present package):

  $ time nix build nixpkgs:firefox

  real    0m1.497s
  user    0m1.160s
  sys     0m0.139s

  $ time nix build nixpkgs:firefox

  real    0m0.052s
  user    0m0.038s
  sys     0m0.007s

The cache is ~/.cache/nix/eval-cache-v1.sqlite, which has entries like

  INSERT INTO Attributes VALUES(
    X'92a907d4efe933af2a46959b082cdff176aa5bfeb47a98fabd234809a67ab195',
    'packages.firefox',
    1,
    '/nix/store/pbalzf8x19hckr8cwdv62rd6g0lqgc38-firefox-67.0.drv /nix/store/g6q0gx0v6xvdnizp8lrcw7c4gdkzana0-firefox-67.0 out');

where the hash 92a9... is a fingerprint over the flake store path and
the contents of the lockfile. Because flakes are evaluated in pure
mode, this uniquely identifies the evaluation result.

4a3e96281d Handle SIGWINCH in main thread 
For the SIGWINCH signal to be caught, it needs to be set in sigaction
on the main thread. Previously, this was broken, and updateWindowSize
was never being called. Tested on macOS 10.14.

Make flake input fetching lazy 
As long as the flake input is locked, it is now only fetched when it
is evaluated (e.g. "nixpkgs" is fetched when
"inputs.nixpkgs.<something>" is evaluated).

This required adding an "id" attribute to the members of "inputs" in
lockfiles, e.g.

  "inputs": {
    "nixpkgs/release-19.03": {
      "id": "nixpkgs",
      "inputs": {},
      "narHash": "sha256-eYtxncIMFVmOHaHBtTdPGcs/AnJqKqA6tHCm0UmPYQU=",
      "nonFlakeInputs": {},
      "uri": "github:edolstra/nixpkgs/e9d5882bb861dc48f8d46960e7c820efdbe8f9c1"
    }
  }

because the flake ID needs to be known beforehand to construct the
"inputs" attrset.

Fixes #2913.

Add 'nix app' command 
This is like 'nix run', except that the command to execute is defined
in a flake output, e.g.

  defaultApp = {
    type = "app";
    program = "${packages.blender_2_80}/bin/blender";
  };

Thus you can do

  $ nix app blender-bin

to start Blender from the 'blender-bin' flake.

In the future, we can extend this with sandboxing. (For example we
would want to be able to specify that Blender should not have network
access by default and should only have access to certain paths in the
user's home directory.)

90fe1dfd2f Register flake source trees as GC roots 
This ensures that flakes don't get garbage-collected, which is
important to get nix-channel-like behaviour.

For example, running

  $ nix build hydra:

will create a GC root

  ~/.cache/nix/flake-closures/hydra -> /nix/store/xarfiqcwa4w8r4qpz1a769xxs8c3phgn-flake-closure

where the contents/references of the linked file in the store are the
flake source trees used by the 'hydra' flake:

  /nix/store/n6d5f5lkpfjbmkyby0nlg8y1wbkmbc7i-source
  /nix/store/vbkg4zy1qd29fnhflsv9k2j9jnbqd5m2-source
  /nix/store/z46xni7d47s5wk694359mq9ay353ar94-source

Note that this in itself is not enough to allow offline use; the
fetcher for the flakeref (e.g. fetchGit or downloadCached) must not
fail if it cannot fetch the latest version of the file, so long as it
knows a cached version.

Also, make fetchGit and fetchMercurial update allowedPaths properly.

(Maybe the evaluator, rather than the caller of the evaluator, should
apply toRealPath(), but that's a bigger change.)

6ade7ec022 progress-bar: hide expected if expected is 0 (unknown) 
Sometimes, "expected" can be "0", but in fact means "unknown".

This is for example the case when downloading a file while the http
server doesn't send the `Content-Length` header, like when running `nix
build` pointing to a nixpkgs checkout streamed from GitHub:

⇒  nix build -f https://github.com/NixOS/nixpkgs/archive/master.tar.gz hello
[1.8/0.0 MiB DL] downloading 'https://github.com/NixOS/nixpkgs/archive/master.tar.gz'

In that case, don't show that weird progress bar, but only the (slowly
increasing) downloaded size ("done").

⇒  nix build -f https://github.com/NixOS/nixpkgs/archive/master.tar.gz hello
[1.8 MiB DL] downloading 'https://github.com/NixOS/nixpkgs/archive/master.tar.gz'

This commit also updates fmt calls with three numbers (when something is
currently 'running' too) - I'm not sure if this can be provoked, but
showing "0" as expected doesn't make any sense, as we're obviously doing
more than nothing.

2b8c63f303 Add 'nix dev-shell' and 'nix print-dev-env' command 
'nix dev-shell' is intended to replace nix-shell. It supports flakes,
e.g.

  $ nix dev-shell nixpkgs:hello

starts a bash shell providing an environment for building 'hello'.

Like Lorri (and unlike nix-shell), it computes the build environment
by building a modified top-level derivation that writes the
environment after running $stdenv/setup to $out and exits. This
provides some caching, so it's faster than nix-shell in some cases
(especially for packages with lots of dependencies, where the setup
script takes a long time).

There also is a command 'nix print-dev-env' that prints out shell code
for setting up the build environment in an existing shell, e.g.

  $ . <(nix print-dev-env nixpkgs:hello)
