Previously many of the documentation targets were depending on
`$(bindir)/nix` which is the installed version. This meant that its
install rules would be triggered (which in chain would also trigger the
install of libraries, as reported in #5140). Therefore a build of the
documentation without an installation would not be possible (which apart
from doing unwanted operations it may also generate permission problems
for example).
The fix makes the rules depend on `$(nix_PATH)` instead, which is the
executable in the build tree.
`installcheck` doesn't yet work, but the rest of the build can now
happen mostly inside a separate build directory.
Progress on #9342

up to now, those were managed outside of this repo, which as
unsurprisingly a real hassle to deal with if one wanted to prevent URLs
from breaking when moving pages around. this change removes a large part
of the friction involved in moving content in the Nix manual.
possible next steps for further automation:
- check for content that moved and warn if it's not reachable from
links that were valid prior to a change
- create redirect rules automatically based on this information
nix-repl> bools = [ false true ]
nix-repl> combinations = builtins.concatMap (a: builtins.concatMap (b: map (c: { inherit a b c; }) bools) bools) bools
nix-repl> builtins.all ({ a, b, c }: (a -> b -> c) == (a -> (b -> c))) combinations
true
nix-repl> builtins.all ({ a, b, c }: (a -> b -> c) == ((a -> b) -> c)) combinations
false
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.
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 publicKeys as an optional fetcher input attribute to flakes
and builtins.fetchGit to provide a nix interface for the json-encoded
`publicKeys` attribute of the git fetcher.

update the glossary to point to the new page.
since this is a cross-cutting concern, it warrants its own section in
the manual.

* document the store concept and its purpose
reword the glossary to link to more existing information instead of
repeating it.
move the store documentation to the top of the table of contents, in
front of the Nix language. this will provide a natural place to
document other aspects of the store as well as the various store types.
move the package management section after the Nix language and before
Advanced Topics to follow the pattern to layer more complex concepts on
top of each other.
this structure of the manual will also nudge beginners to learn Nix
bottom-up and hopefully make more likely that they understand underlying
concepts first before delving into complex use cases that may or may not
be easy to implement with what's currently there.
[John adds this note] The sort of beginner who likes to dive straight into reference documentation should prefer this approach. Conversely, the sort of beginner who would prefer the opposite top-down approach of trying to solve problems before they understand everything that is going on is better off reading other tutorial/guide material anyways, and will just "random-access" the reference manual as a last resort. For such random-access the order doesn't matter, so this restructure doesn't make them any worse off.

Rather than having a misc tutorial page in the grab-bag "package management" section, this information should just be part of the S3 store docs.

Single quotes are a basic feature of shell syntax that people expect to
work. They are also more convenient for writing literal code expressions
with less escaping.
this is the first thing most beginners see, and it misleads them into
assuming `nix-env` is appropriate for doing anything but setting and
reverting profile generations.
this chapter is the root of most evil around the ecosystem, and today we
finally close it for good.
