indexed when it is bad.
lix/lix2 » nix eval --expr '{x.y = 2;}' 'x.y.z'
error: the value being indexed in the selection path 'x.y.z' at 'x.y' should be a set but is an integer: 2
lix/lix2 » nix eval --expr '{x.y = { a = 3; };}' 'x.y.z'
error: attribute 'z' in selection path 'x.y.z' not found inside path 'x.y', whose contents are: { a = 3; }
Did you mean a?

error: the expression selected by the selection path 'x.y.1' should be a list but is a set: { a = 3; }

after. doing it any other way leads to interesting things like #596.

It was never intended to be a feature to be used, and moreover it is
inconsistent: One cannot override `+`, and overriding `__lessThan` won't
affect the builtins which do comparisons.

this also fixes a debugger bug where leaving the debugger does not clean
up old debugger state completely. in such cases the fake frame withFrame
created was left behind after the corresponding caller frame was unwound

checking whether a repl hook is set does not tell whether it's running,
which in turn means we will enter a debug repl even when not debugging.
this is not very useful when we have no debug frames to inspect at all,
as commonly happens when starting a new repl with --debugger specified.

clangd broke because it can't look through symlinks. compile_commands
manipulation does not fix it, clangd configuration does not fix it, a
vfs overlay does not fix it, and while a combination of those can fix
it with a bind mount in place that's just too cursed to even consider

This adds a new temp-dir setting for controlling the temporary directory
without having to change the TMPDIR env var. This can be used to e.g.
use a path on a case-sensitive store on macOS for temporary files
without changing the TMPDIR var used by interactive shells or commands
invoked with `nix run`.
This also stops unsetting `TMPDIR` on darwin when the env var value
starts with `/var/folders/`, preferring instead to just do the check
when reading `TMPDIR`. This way the inherited `TMPDIR` env var is
preserved for child processes (such as interactive shells).
As a side effect this changes the behavior of `nix-build -o ''` to act
like `nix-build --no-out-link` instead of failing with an error caused
by trying to create a symlink at the cwd.

This reverts commit 02c35ea9df.
Reason for revert: this code path is also used for `Input::getRev()`, i.e. flakes VCS revision validation, which, in the case of Git, are using SHA1.
As a result, this cause too much noise due to SHA1 revisions in Flakes.

It's only used in a couple of tests, and only in such a way that
replacing it with a random command suffices.
I also removed a few pointless uses of the variable.

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).
Change-Id: I0d78d6220ca6aeaa10bc437e48e08bf7922e0bb3
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.

Before this change, expressions like:
with import <nixpkgs> {};
runCommand "foo" {} ''
echo '@nix {}' >&$NIX_LOG_FD
''
would result in Lix crashing, because accessing nonexistent fields of
a JSON object throws an exception.
Rather than handling each field individually, we just catch JSON
exceptions wholesale. Since these log messages are an unusual
circumstance, log a warning when this happens.
Fixes#544.

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
test hanging forever, with no children of the bash process.
