It works with both `ssh://` and `ssh-ng://` now since #9600 (and
`ssh-ng:// didn't work before that).
Also, by making the two tests share code, we nudge ourselves towards
making sure there is feature parity.
I don't love the way this code looks. There are two larger problems:
- eval, build/scratch, destination stores (#5025) should have different
types to reflect the fact that they are used for different purposes
and those purposes correspond to different operations. It should be
impossible to "use the wrong store" in my cases.
- Since drvs can end up in both the eval and build/scratch store, we
should have some sort of union/layered store (not on the file sytem
level, just conceptual level) that allows accessing both. This would
get rid of the ugly "check both" boilerplate in this PR.
Still, it might be better to land this now / soon after minimal cleanup,
so we have a concrete idea of what problem better abstractions are
supposed to solve.
* Print the value in `error: cannot coerce` messages
This extends the `error: cannot coerce a TYPE to a string` message
to print the value that could not be coerced. This helps with debugging
by making it easier to track down where the value is being produced
from, especially in errors with deep or unhelpful stack traces.

This includes position information in more places, making debugging
easier.
Before:
```
$ nix-instantiate --show-trace --eval tests/functional/lang/eval-fail-using-set-as-attr-name.nix
error:
… while evaluating an attribute name
at «none»:0: (source not available)
error: value is a set while a string was expected
```
After:
```
error:
… while evaluating an attribute name
at /pwd/lang/eval-fail-using-set-as-attr-name.nix:5:10:
4| in
5| attr.${key}
| ^

error: value is a set while a string was expected
```
`installcheck` doesn't yet work, but the rest of the build can now
happen mostly inside a separate build directory.
Progress on #9342

The basic idea here is to separate a few intertwined notions:
1. Not all "run bash tests" are "install tests"
2. Not all "run bash tests" use `tests/functional/init.sh`, or any
pre-test initialization at all.
This will used in the next commit when we have a test that check unit
test golden master data.
Also, move our custom `PS4` from the test to the test runner, as it is
part of how we want to display the tests, not the test themselves.

As discussed in our last meeting, we need a bit more time, but we are
"time boxing" the work left to do to ensure there is not unbounded
delay.
Rather than putting it back underneath `flakes`, though, put it
underneath its own `fetch-tree` experimental feature (which `flakes`
includes/implies). This signals our commitment to the plan to stabilize
it first without waiting to go through the rest of Flakes, and also will
give users a "release candidate" when we get closer to stabilization.
This reverts commit 4112dd1fc9.
Enables shebang usage of nix shell. All arguments with `#! nix` get
added to the nix invocation. This implementation does NOT set any
additional arguments other than placing the script path itself as the
first argument such that the interpreter can utilize it.
Example below:
```
#!/usr/bin/env nix
#! nix shell --quiet
#! nix nixpkgs#bash
#! nix nixpkgs#shellcheck
#! nix nixpkgs#hello
#! nix --ignore-environment --command bash
# shellcheck shell=bash
set -eu
shellcheck "$0" || exit 1
function main {
hello
echo 0:"$0" 1:"$1" 2:"$2"
}
"$@"
```
fix: include programName usage
EDIT: For posterity I've changed shellwords to shellwords2 in order
not to interfere with other changes during a rebase.
shellwords2 is removed in a later commit. -- roberth
* Fix boost::bad_format_string exception in builtins.addErrorContext
The message passed to addTrace was incorrectly being used as a format
string and this this would cause an exception when the string contained
a '%', which can be hit in places where arbitrary file paths are
interpolated.
* add test
Before it returned a list of JSON objects with store object information,
including the path in each object. Now, it maps the paths to JSON
objects with the metadata sans path.
This matches how `nix derivation show` works.
Quite hillariously, none of our existing functional tests caught this
change to `path-info --json` though they did use it. So just new
functional tests need to be added.
This adds simple tests of the commit signature verification mechanism of
fetchGit and its flake input wrapper.
OpenSSH is added to the build dependencies since it's needed to create
a key when testing the functionality. It is neither a built- nor a
runtime dependency.
