The old behavior results in lots of concatenations happening for no good
reason and is an artifact of the technical limitations of the old parser
(combined with some lack of care for such details).

This is only a minor semantical distinction, but we should be able to
properly test it, and the parser tests rely on show for that.

This was always a terrible idea independently of whether it crashes.
Stop doing it!
This commit was verified by running nix-shell on a trivial derivation
with --debug --verbose to get the vomit-level output of the shell rc
file and then diffing it before/after this change. I have reasonable
confidence it did not regress anything, though this code is genuinely
really hard to follow (which is a second reason that I split it into two
fmt calls).

When the git default branch is not set to master the installcheck
test suite fails. This patch adjusts the test setup scripts to
ignore the system and user git config files.
GIT_CONFIG_SYSTEM is set to /dev/null to ignore /etc/gitconfig
GIT_CONFIG_GLOBAL is not set because the global config files
are loaded from $HOME or $XDG_CONFIG_HOME which we already
reset.

with async runtime scheduling we can no longer guarantee exact error
counts for builds that do not set keepGoing. the old behavior can be
recovered with a number of hacks that affect scheduling, but none of
those are very easy to follow now advisable. exact error counts will
like not be needed for almost all uses except tests, and *those* had
better check the actual messages rather than how many they got. more
messages can even help to avoid unnecessary rebuilds for most users.

This moves the "legacy"/"nix2" commands under a new `src/legacy/`
directory, instead of being scattered around in a bunch of different
directories.
A new `liblegacy` build target is defined, and the `nix` binary is
linked against it.
Then, `RegisterLegacyCommand` is replaced with `LegacyCommand::add`
calls in functions like `registerNixCollectGarbage()`. These
registration functions are called explicitly in `src/nix/main.cc`.

this was a debugging aid from day one that should not have any impact on
build semantics, and if it *does* have an impact on build semantics then
build semantics are seriously broken. keeping the order imposed by these
keys will be impossible once we let a real event loop schedule our jobs.
Change-Id: I5c313324e1f213ab6453d82f41ae5e59de809a5b
the new event loop could very occasionally notice that a dependency of
some goal has failed, process the failure, cause the depending goal to
fail accordingly, and in the doing of the latter two steps let further
dependencies that previously have not been reported as failed do their
reporting anyway. in such cases a goal could fail with "1 dependencies
failed", but more than one dependency failure message was shown. we'll
now report the correct number of failed dependency goals in all cases.

Since fb38459d6e, each `ref` is appended
with `refs/heads` unless it starts with `refs/` already. This regressed
two use-cases that worked fine before:
* Specifying a commit hash as `ref`: now, if `ref` looks like a commit
hash it will be directly passed to `git fetch`.
* Specifying a tag without `refs/tags` as prefix: now, the fetcher prepends
`refs/*` to a ref that doesn't start with `refs/` and doesn't look
like a commit hash. That way, both a branch and a tag specified in
`ref` can be fetched.
The order of preference in git is
* file in `refs/` (e.g. `HEAD`)
* file in `refs/tags/`
* file in `refs/heads` (i.e. a branch)
After fetching `refs/*`, ref is resolved the same way as git does.

When `nix fmt` is called without an argument, Nix appends the "." argument before calling the formatter. The comment in the code is:
> Format the current flake out of the box
This also happens when formatting sub-folders.
This means that the formatter is now unable to distinguish, as an interface, whether the "." argument is coming from the flake or the user's intent to format the current folder. This decision should be up to the formatter.
Treefmt, for example, will automatically look up the project's root and format all the files. This is the desired behaviour. But because the "." argument is passed, it cannot function as expected.

The <() process substitution syntax doesn't work for this one testcase

do with pipe vs file vs fifo EOF behavior. The prior behavior was this

Closes#460
I managed to trigger the issue by having the following inputs (shortened):
authentik-nix.url = "github:nix-community/authentik-nix";
authentik-nix.inputs.poetry2nix.inputs.nixpkgs.follows = "nixpkgs";
When evaluating this using
nix-eval-jobs --flake .#hydraJobs
I got the following error:
error: cannot update unlocked flake input 'authentik-nix/poetry2nix' in pure mode
The issue we have here is that `authentik-nix/poetry2nix` was written
into the `overrideMap` which caused Nix to assume it's a new input and
tried to refetch it (#460) or errored out in pure mode
(nix-eval-jobs / Hydra).
The testcase unfortunately only involves checking for the output log
and makes sure that something *is* logged on the first fetch so that
the test doesn't rot when the logging changes since I didn't
manage to trigger the error above with the reproducer from #460. In
fact, I only managed to trigger the `cannot update unlocked flake input`
error in this context with `nix-eval-jobs`.

Turns out strings do not like being resized to -4.
This was discovered while messing with the tests to remove unbuffer and
trying stdbuf instead. Turns out that was not the right approach.
This basically rewrites the handling of this case to be much more
correct, and fixes a bug where with small window sizes where it would
ALSO truncate the attr names in addition to the optional descriptions.

I was packaging Lix 2.91 for nixpkgs and was annoyed at the expect
dependency. Turns out that you can replace unbuffer with a pretty-short
Python script.
It became less short after I found out that Linux was converting \n to
\r\n in the terminal subsystem, which was not very funny, but is at
least solved by twiddling termios bits.

This adds a second form to the `:log` command: it now can accept a

store paths start with `/nix/store`, this is not ambiguous.

This was always in the lock file and we can simply actually print it.
The test for this is a little bit silly but it should correctly

This *should* be sound, plus or minus the amount that the terminal code
eating code is messed up already.
This is useful for testing CLI output because it will strip the escapes
enough to just shove the expected output in a file.

The original attempt at this introduced a regression; this commit
reverts the revert and fixes the regression.
This reverts commit 3e151d4d77.
Fix to the regression:
flakeref: fix handling of `?dir=` param for flakes in subdirs
As reported in #419[1], accessing a flake in a subdir of a Git
repository fails with the previous commit[2] applied with the error
error: unsupported Git input attribute 'dir'
The problem is that the `dir`-param is inserted into the parsed URL if a
flake is fetched from the subdir of a Git repository. However, for the
fetching part this isn't even needed. The fix is to just pass `subdir`
as second argument to `FlakeRef` (which needs a `basedir` that can be
empty) and leave the parsedURL as-is.
Added a regression test to make sure we don't run into this again.

This removes a *whole load* of variables from scope and enforces thread
boundaries with the type system.
There is not much change of significance in here, so the things to watch
out for while reviewing it are primarily that the destructor ordering
may have changed inadvertently, I think.

When pretty-printing is enabled, previously an unforced thunk would trigger
indentation, even when it subsequently does not evaluate to a nested structure.
The resulting output looked inconsistent, and furthermore pretty-printing was
not idempotent (since pretty-printing the same value again, which is now fully
evaluated, will not trigger indentation).
When strict evaluation is enabled, force the item before inspecting its type,
so that it is properly known whether it contains a nested structure.
Furthermore, there is no need to cause indentation for unforced thunks, since
the very next operation will be printing them as `«thunk»`.
This is mostly a port of https://github.com/NixOS/nix/pull/11100 , but we only
force the item when it's going to be forced anyway due to strict
pretty-printing, and a new test was written since the REPL testing framework in
Lix is different.

Previous test implementation assumed that grep supports newlines
in patterns. It doesn't, so tests spuriously passed, even though
some tests outputs were broken.
This patches output (and expected output) before grepping,
so there're no newlines in pattern.
