easier.

`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.
Adding the inputPath as a positional feature uncovered this bug.
As positional argument forms were discarded from the `expectedArgs`
list, their closures were not. When the `.completer` closure was then
called, part of the surrounding object did not exist anymore.
This didn't cause an issue before, but with the new call to
`getEvalState()` in the "inputs" completer in nix/flake.cc, a segfault
was triggered reproducibly on invalid memory access to the `this`
pointer, which was always 0.
The solution of splicing the argument forms into a new list to extend
their lifetime is a bit of a hack, but I was unable to get the "nicer"
iterator-based solution to work.
Instead of making a complete copy of the repo, fetching the
submodules, and writing the result to the store (which is all
superexpensive), we now fetch the submodules recursively using the Git
fetcher, and return a union accessor that "mounts" the accessors for
the submodules on top of the root accessor.
End goal: make `(mkDerivation x).drvPath` behave like a non-DrvDeep
context.
Problem: users won't be able to recover the DrvDeep behavior when
nixpkgs makes this change.
Solution: add this primop.
The new primop is fairly simple, and is supposed to complement other
existing ones (`builtins.storePath`, `builtins.outputOf`) so there are
simple ways to construct strings with every type of string context
element.
(It allows nothing we couldn't already do with `builtins.getContext` and `builtins.appendContext`, which is also true of those other two primops.)
This was originally in #8595, but then it was proposed to land some doc
changes separately. So now the code changes proper is just moved to
this, and the doc will be done in that.
