Adds Nix CLI Guideline to docs 
As we are working towards Nix 3.0 we want to make sure that we make a
huge step forward in Nix's user experience. And once 3.0 is out of the
door we need to make sure that all future commands and features keep up
the standard of user experience.

This PR adds a CLI guideline document to the Nix documentation. Consider
this document a good starting point and a checklist when somebody will
be (re)implementing commands.

Clearly this guideline does nothing to improve user experience on its
own and can only be useful as long as it is going to be read and
cared for. But it is a first step into that direction.

preallocateContents option: disable by default
 2020-11-26 15:01:43 +01:00
Dominique Martinet 1fd13d67e8 archive: disable preallocate-contents by default 
using fallocate() to preallocate files space does more harm than good:
 - breaks compression on btrfs
 - has been called "not the right thing to do" by xfs developers
(because delayed allocation that most filesystems implement leads to smarter
allocation than what the filesystem needs to do if we upfront fallocate files)

Fabian Möller 5b0790355f
Fix macOS sandbox build 
Since c4c3c15c19 (#4251) building Nix for
macOS with sandboxing fails:
```
getting status of /nix/var/nix/profiles/per-user/root/channels/nixpkgs: Operation not permitted
```

This happens, because `EvalSettings::getDefaultNixPath` tries to access
paths outside the sandbox. Since the state-dir is not required for
doc generation, it is set to the dummy folder. This needs to be done
for all nix invocations during doc generation, as
`EvalSettings::getDefaultNixPath` is called unconditionally.

Luke Granger-Brown 226116f482 fetchMercurial: set HGPLAIN when invoking hg 
Without setting HGPLAIN, the user's environment leaks into
hg invocations, which means that the output may not be in the
expected format.

HGPLAIN is the Mercurial-recommended solution for this in that
it's intended for uses by scripts and programs which are looking
to parse Mercurial's output in a consistent manner.

installer: simplify the per-build installation 
The goal is to allow the installation and testing of arbitrary Nix
versions. Extend the base installer to accept a `--tarball-url-prefix
<url>` to change where the Nix tarball is getting downloaded from.

Once this is merged it should allow to:
1. Pick an evaluation at https://hydra.nixos.org/jobset/nix/master that
   looks healthy
2. Select the installedScript build and find the store path.

Now equipped with all of this, use an instance of nar-serve to fetch the
install script and release tarballs:

    curl -sfL https://nar-serve.numtide.com/nix/store/rkv4yh7pym941bhj0849zqdkg2546bdv-installer-script/install \
      | sh --tarball-url-prefix https://nar-serve.numtide.com/nix/store

Or with cachix, strip the /nix/store and derivation name and then:

    curl -sfL https://mycache.cachix.org/serve/rkv4yh7pym941bhj0849zqdkg2546bdv/install \
      | sh --tarball-url-prefix https://mycache.cachix.org/serve
