mdbook-linkcheck is not consistent about its warning setting.
It disables some warnings, but not the warnings about lack of
fragment checking support; hence the extra filtering.
This runs the installer in a QEMU VM. Unlike the old installer test
that ran inside a declaratively built RedHat/Debian image, this uses
an image from Vagrant.
With this, Nix will write a copy of the sandbox shell to /bin/sh in
the sandbox rather than bind-mounting it from the host filesystem.
This makes /bin/sh work out of the box with nix-static, i.e. you no
longer get
/nix/store/qa36xhc5gpf42l3z1a8m1lysi40l9p7s-bootstrap-stage4-stdenv-linux/setup: ./configure: /bin/sh: bad interpreter: No such file or directory
Python is only pulled into the build closure by Mercurial, which might end up being removed.
Let’s port the script to jq, which is more likely to stay.
Apart from a slight simplification and a bit of dogfooding, this also
make the cache behavior more predictable.
For example `nix build .` and `nix build nix/$(git rev-parse HEAD)` will
yield the exact same path, while their “intuitive” non-flake equivalents
(`nix-build` and
`nix-build https://github.com/nixos/nix/archives/$(git rev-parse HEAD).tar.gz`)
don’t.
This was a pain for example in https://github.com/NixOS/nix/pull/5059
Also, the `bar-with-logs` log format is imho nicer (even in an
non-interactive context) because prefixing each log line with the name
of the derivation that produced it makes it much easier to follow what’s
going on.
We explicitly hack around to remove them, so might as well check that
the hack is useful.
(Introduced because I feared that the changes of
https://github.com/NixOS/nix/pull/5906#discussion_r784810238 would bring
back some runtime references)
For a (currently hardcoded and limited) list of stdenvs,
make `.#$nix-${stdenvName}` correspond to a Nix built with the
corresponding stdenv.
For example, `.#nix-${clang11Stdenv}` is Nix built with clang11.
Likewise, `devShells.x86_64-linux.clang11StdenvPackages` is a development
shell for Nix with clang11, that can be used with
```shell
nix develop .#clang11StdenvPackages
```
