4baf8548fb types.singleLineStr: Allow and trim trailing \n
Allow a \n character at the end of the string and remove it during the
merge function.

An option of this type will resolve to the value "foo" whether it is set
to "foo" or "foo\n".

This is useful when using 'builtins.readFile' or ''-strings, which might
add an unintended newline (for example, bash trim the final newline from
a subshell).

48965506a1 lib/asserts: use throw to display message for assertMsg
`assert` has the annoying property that it dumps a lot of code at the
user without the built in capability to display a nicer message. We have
worked around this using `assertMsg` which would *additionally* display
a nice message. We can do even better: By using `throw` we can make
evaluation fail before assert draws its conclusions and prevent it from
displaying the code making up the assert condition, so we get the nicer
message of `throw` and the syntactical convenience of `assert`.

Before:

    nix-repl> python.override { reproducibleBuild = true; stripBytecode = false; }
    trace: Deterministic builds require stripping bytecode.
    error: assertion (((lib).assertMsg  (reproducibleBuild -> stripBytecode))  "Deterministic builds require stripping bytecode.") failed at /home/lukas/src/nix/nixpkgs/pkgs/development/interpreters/python/cpython/2.7/default.nix:45:1

After:

    nix-repl> python.override { reproducibleBuild = true; stripBytecode = false; }
    error: Deterministic builds require stripping bytecode.

df590070b0 types.singleLineStr: strings that don't contain '\n'
Add a new type, inheriting 'types.str' but checking whether the value
doesn't contain any newline characters.

The motivation comes from a problem with the
'users.users.${u}.openssh.authorizedKeys' option.
It is easy to unintentionally insert a newline character at the end of a
string, or even in the middle, for example:

    restricted_ssh_keys = command: keys:
      let
        prefix = ''
          command="${command}",no-pty,no-agent-forwarding,no-port-forwarding,no-X11-forwarding
        '';
      in map (key: "${prefix} ${key}") keys;

The 'prefix' string ends with a newline, which ends up in the middle of
a key entry after a few manipulations.

This is problematic because the key file is built by concatenating all
the keys with 'concatStringsSep "\n"', with result in two entries for
the faulty key:

    ''
      command="...",options...
      MY_KEY
    ''

This is hard to debug and might be dangerous. This is now caught at
build time.

fc614c37c6 nixos/documentation: split options doc build
most modules can be evaluated for their documentation in a very
restricted environment that doesn't include all of nixpkgs. this
evaluation can then be cached and reused for subsequent builds, merging
only documentation that has changed into the cached set. since nixos
ships with a large number of modules of which only a few are used in any
given config this can save evaluation a huge percentage of nixos
options available in any given config.

in tests of this caching, despite having to copy most of nixos/, saves
about 80% of the time needed to build the system manual, or about two
second on the machine used for testing. build time for a full system
config shrank from 9.4s to 7.4s, while turning documentation off
entirely shortened the build to 7.1s.

- Eta reduce formal arguments of `recursiveUpdate'.
- Access elements in `recursiveUpdateUntil` using `elemAt` and `head`
  directly instead of `head (tail xs)` which copies a singleton unnecessarily.
  (`elemAt` is used instead of `last` to save a primitive call to `length`,
  this is possible because the 2-tuple structure is guranteed)
- Use `length` instead of comparison to empty list to save a copy.

afecbb2f75 lib/modules: optimize byName
the foldl is equivalent to a zip with concat. list concatenation in nix
is an O(n) operation, which makes this operation extremely inefficient
when large numbers of modules are involved.

this change reduces the number of list elements by 7 million on the
system used to write this, total memory spent on lists by 58MB, and
total memory allocated on the GC heap by almost 100MB (with a similar
reduction in GC heap size). it's also slightly faster.

9066c52e5a lib.systems.supported: remove aarch64-darwin from Tier 3 list
While it is a fact of life that aarch64-darwin is built on Hydra, it has
never formally been elevated from the Tier 7 state it was originally
assigned in RFC 0046. Since platform Tier status is not only
descriptive, but also normative, a consensus to commit to supporting
aarch64-darwin would need to be reached.

Makes any programming errors more likely to show up early.

Non-obvious changes because of this:

- Ignore the `evalConfig` result in `reportFailure`; we're not checking

- Pre-increment `$fail` and `$pass` to make sure the arithmetic doesn't
  result in a zero, which would result in a non-zero exit code for the

mkDerivedConfig : Option a -> (a -> Definition b) -> Definition b

Create config definitions with the same priority as the definition of another option.
This should be used for option definitions where one option sets the value of another as a convenience.
For instance a config file could be set with a `text` or `source` option, where text translates to a `source`
value using `mkDerivedConfig options.text (pkgs.writeText "filename.conf")`.

It takes care of setting the right priority using `mkOverride`.

cd6397519f lib/lists: mutuallyExclusive function optimization
The current implementation of `mutuallyExclusive` builds a new list with
length subtracted by one on every recursive call which is expensive. When
b is empty, the function still traverses a in its entirety before returning
a result.

The new implementation uses `any` to check if each element of list b is in
list a using `elem`. This maintains short circuiting when list a or b is empty
and has a worst case time complexity of O(nm).

the fix to extendDerivation in #140051 unwittingly worsened eval performance by
quite a bit. set elements alone needed over 1GB extra after the change, which
seems disproportionate to how small it was. if we flip the logic used to
determine which outputs to install around and keep a "this one exactly" flag in
the specific outputs instead of a "all of them" in the root we can avoid most
of that cost.

9b3b8f74bb fix nested calls to extendDerivation
if extendDerivation is called on something that already had extendDerivation
called on it (eg a mkDerivation result) the second call will set
outputUnspecified=true on every output by way of propagating attributes of the
full derivation to the individual outputs. this in turn causes buildEnv--and
thus nix-shell and environment.systemPackages--to install every output of such a
derivation even when only a specific output was requested, which renders the
point of multiple outputs moot. this happens in python modules (see #139756),
though it seems that tcl and possibly others should also be affected.

I'm working on a project that involves running a virtual machine

This obviously isn't part of the source of my program, so I think
cleanSource should filter it out.

de81edf6ef lib/strings: fix infinite recursion on concatStringsSep fallback
The current implementation of the concatStringsSep fallback references
concatStrings whcih is just a partial application of concatStringsSep,
forming a circular dependency. Although this will almost never be
encountered as (assuming the user does not explicitly trigger it):
  1. the or operator will short circuit both in lazy and strict
     evaluation
  2. this can only occur in Nix versions prior to 1.10
     which is not compatible with various nix operations as of 2.3.15

However it is still important if scopedImport is used or the builtins
have been overwritten. lib.foldl' is used instead of builtins.foldl'
as the foldl' primops was introduced in the same release as concatStringsSep.

lib/modules: fix error-message when declaring an option inside `config'
The message I originally implemented here was to catch a mixup of
`config' and `options' in a `types.submodule'[1]. However it looks
rather weird for a wrongly declared top-level option.

So I decided to throw

    error: The option `foo' does not exist. Definition values:
           - In `<unknown-file>':
               {
                 bar = {
                   _type = "option";
                   type = {
                     _type = "option-type";
               ...

           It seems as you're trying to declare an option by placing it into `config' rather than `options'!

for an expression like

    with import ./lib;

    evalModules {
      modules = [
        {
          foo.bar = mkOption {
            type = types.str;
          };
        }
      ];
    }

lib/options: use depthLimit for toPretty when showing a definition
When having a bogus declaration such as

    { lib, ... }:
    {
      foo.bar = mkOption {
        type = types.str;
      };
    }

the evaluation will terminate with a not-so helpful

    error: stack overflow (possible infinite recursion)

To make sure a useful error is still provided, I added a `depthLimit` of
`10` which should be perfectly sufficient to `toPretty` when it's used
in an error-case for `showDefs`.

lib/generators/toPretty: add evaluation-limit
When having e.g. recursive attr-set, it cannot be printed which is
solved by Nix itself like this:

    $ nix-instantiate --eval -E 'let a.b = 1; a.c = a; in builtins.trace a 1'
    trace: { b = 1; c = <CYCLE>; }
    1

However, `generators.toPretty` tries to evaluate something until it's
done which can result in a spurious `stack-overflow`-error:

    $ nix-instantiate --eval -E 'with import <nixpkgs/lib>; generators.toPretty {  } (mkOption { type = types.str; })'
    error: stack overflow (possible infinite recursion)

Those attr-sets are in fact rather common, one example is shown above, a
`types.<type>`-declaration is such an example. By adding an optional
`depthLimit`-argument, `toPretty` will stop evaluating as soon as the
limit is reached:

    $ nix-instantiate --eval -E 'with import ./Projects/nixpkgs-update-int/lib; generators.toPretty { depthLimit = 2; } (mkOption { type = types.str; })' |xargs -0 echo -e
    "{
      _type = \"option\";
      type = {
        _type = \"option-type\";
        check = <function>;
        deprecationMessage = null;
        description = \"string\";
        emptyValue = { };
        functor = {
          binOp = <unevaluated>;
          name = <unevaluated>;
          payload = <unevaluated>;
          type = <unevaluated>;
          wrapped = <unevaluated>;
        };
        getSubModules = null;
        getSubOptions = <function>;
        merge = <function>;
        name = \"str\";
        nestedTypes = { };
        substSubModules = <function>;
        typeMerge = <function>;
      };
    }"

Optionally, it's also possible to let `toPretty` throw an error if the
limit is exceeded.

This allows checking e.g. stdenv.hostPlatform.isGnu, just like isMusl

stdenv.hostPlatform.libc == "glibc", but when that doesn't line up
with how every other platform check works, this is apparently
sufficiently non-obvious that we've ended up with stuff like adding
glibc.static if !isMusl, which is obviously wrong.

This regressed in 9c213398b3

The recursiveUpdate gave the platform both gcc.cpu and gcc.arch attrs
instead of only gcc.cpu. This is invalid; gcc configuration fails with:

```
Switch "--with-arch" may not be used with switch "--with-cpu"
```

So we revert to using `//` to retain only gcc.cpu
(which is more specific than the processor arch).

998a9c1707 lib/options: Better mergeEqualOption error for uncomparable types
For an option definition that uses `lib.options.mergeEqualOption`
underneath, like `types.anything`, an error is thrown when multiple
functions are assigned, indicating that functions can't be compared for
equivalence:

  error: The option `test' has conflicting definition values:
  - In `xxx': <function>
  - In `xxx': <function>
  (use '--show-trace' to show detailed location information)

However, the error message didn't use the correct files. While above
error indicates that both definitions are in the xxx file, that's in
fact not true. Above error was generated with

  options.test = lib.mkOption {
    type = lib.types.anything;
  };

  imports = [
    {
      _file = "yyy";
      test = y: y;
    }
    {
      _file = "xxx";
      test = x: x;
    }
  ];

With this change, the error uses the correct file locations:

  error: The option `test' has conflicting definition values:
  - In `xxx': <function>
  - In `yyy': <function>
  (use '--show-trace' to show detailed location information)

1e1d29c2af treewide: Support aarch64-android using minimal prebuilt components
This PR adds a new aarch64 android toolchain, which leverages the
existing crossSystem infrastructure and LLVM builders to generate a
working toolchain with minimal prebuilt components.

The only thing that is prebuilt is the bionic libc. This is because it
is practically impossible to compile bionic outside of an AOSP tree. I
tried and failed, braver souls may prevail. For now I just grab the
relevant binaries from https://android.googlesource.com/.

I also grab the msm kernel sources from there to generate headers. I've
included a minor patch to the existing kernel-headers derivation in
order to expose an internal function.

Everything else, from binutils up, is using stock code. Many thanks to
@Ericson2314 for his help on this, and for building such a powerful
system in the first place!

One motivation for this is to be able to build a toolchain which will
work on an aarch64 linux machine. To my knowledge, there is no existing
toolchain for an aarch64-linux builder and an aarch64-android target.

f39a5c4e50 lib/strings: forbid lists in isStorePath
When a list is passed to isStorePath this is most likely a mistake and
it is therefore better to just return false. There is one case where
this theoretically makes sense (if a list contains a single element for
which isStorePath elem), but since that case is also probably seldomly
intentional, it may save someone from debbuging unclear evaluation
errors.

In particular:

 - Use `lib.makeScopeWithSplicing` to make the `darwin` package set have
   a proper `callPackage`.

 - Adjust Darwin `stdenv`'s overlays keeping things from the previous
   stage to not stick around too much.

 - Expose `binutilsNoLibc` / `darwin.binutilsNoLibc` to hopefully get us

4b54aedee5 lib/modules: Issue type deprecation warnings recursively
Previously, an option of type

  attrsOf string

wouldn't throw a deprecation warning, even though the string type is
deprecated. This was because the deprecation warning trigger only looked
at the type of the option itself, not any of its subtypes.

This commit fixes this, causing each of the types deprecationMessages to
trigger for the option. This relies on the subtypes mkOptionType
attribute introduced in 26607a5a2e06653fec453c83d063cdfc4b59185f

ce5e3113c3 lib/tests: Make sure the submodule type description can be evaluated
In 2d45a62899, the submodule type
description was amended with the freeformType description. This causes
all the modules passed to the submodule to be evaluated once on their
own, without any extra definitions from the config section. This means
that the specified modules need to be valid on their own, without any
undeclared options.

This commit adds a test that evaluates a submodules option description,
which would trigger the above problem for one of the tests, if it were
not fixed by this commit as well.

This is done because the next commit makes option evaluation a bit more
strict, which would also trigger this test failure, even though it's not
related to the change at all.

81e1e68eaf lib.trivial.warnIf: init
It's a common pattern in Nixpkgs to want to emit a warning in certain
cases, but not actually change behaviours.

This is often expressed as either
	if cond then lib.warn "Don't do that thing" x else x
Or
	(if cond then lib.warn "Don't do that thing" else lib.id) x

Neither of which really expresses the intent here, because it looks
like 'x' is being chosen conditionally.

To make this clearer, I introduce a "warnIf" function, which makes it
clear that the only thing being affected by the condition is whether
the warning is generated, not the value being returned.

lib: fix commitIdFromGitRepo (#117752)
When in the presence of worktrees, it happens that /commondir has a
trailing slash.

In these circumstances, it can lead to `lib.pathType` being passed paths
like `/foo/bar/.git/`, which in turn lead to
`error: attribute '.git' missing`.

With this change, we now make sure send properly-formatted paths to all
other functions.

This, in particular, fixes running NixOS tests on worktrees created by
libgit2 on my machine. (Worktrees created by git itself appear to not
hit the issue.)

lib/modules: better error message if an attr-set of options is expected
I recently wrote some Nix code where I wrongly set a value to an option
which wasn't an actual option, but an attr-set of options. The mistake I
made can be demonstrated with an expression like this:

    {
      foo = { lib, pkgs, config, ... }: with lib; {
        options.foo.bar.baz = mkOption {
          type = types.str;
        };
        config.foo.bar = 23;
      };
    }

While it wasn't too hard to find the cause of the mistake for me, it was
necessary to have some practice in reading stack traces from the module
system since the eval-error I got was not very helpful:

    error: --- TypeError --------------------------------------------------------- nix-build
    at: (323:25) in file: /nix/store/3nm31brdz95pj8gch5gms6xwqh0xx55c-source/lib/modules.nix

       322|         foldl' (acc: module:
       323|                 acc // (mapAttrs (n: v:
          |                         ^
       324|                                    (acc.${n} or []) ++ f module v

    value is an integer while a set was expected
    (use '--show-trace' to show detailed location information)

I figured that such an error can be fairly confusing for someone who's
new to NixOS, so I decided to catch this case in th `byName` function in
`lib/modules.nix` by checking if the value to map through is an actual
attr-set. If not, a different error will be thrown.

7f7d5bcd90 lib/licenses: fix regression removing shortName for some licenses
Usually we ensure using the mapAttrs call wrapping the license set that
every license has an associated shortName. A change related to legacy
aliases most likely introduced the removal of the shortName attribute
for all the legacy license names by splitting the set into two sets
connected by a record update operator -- leading to mapAttrs only
affecting the first set.

Since it used to be a valid assumption to have that every license had a
shortName attribute, we reintroduce this attribute for the legacy
aliases as well.

06d3b28987 Revert "lib/generators: fix toPretty throwing on (partially applied) builtins"
This reverts commit d9a7d03da8.

Reason for this is that it actually doesn't migitate the issue on nix
stable for another reason: builtins.tryEval doesn't prevent the error
generated by builtins.functionArgs from halting evaluation:

> builtins.tryEval (builtins.functionArgs builtins.functionArgs)
error: 'functionArgs' requires a function, at (string):1:19

Thus it seems that there is no workaround to make
lib.generators.toPretty work with nix stable and primops since there is
no way to distinguish between primops and lambdas in nix.

d9a7d03da8 lib/generators: fix toPretty throwing on (partially applied) builtins
An high level example case of this problem occuring can be found below:

nix-repl> lib.generators.toPretty {} (lib.concatStringsSep "\n")
error: 'functionArgs' requires a function, at /home/lukas/src/nix/nixpkgs/lib/trivial.nix:334:42

However this does not happen on other partially applied functions:

nix-repl> lib.generators.toPretty {} (lib.concatMapStringsSep "\n")
"<function>"

The issue, as it turns out is that while builtins are functions,
builtins.functionArgs throws if is passed a builtin or a partially
applied builtin:

nix-repl> lib.generators.toPretty {} builtins.toString
error: 'functionArgs' requires a function, at /home/lukas/src/nix/nixpkgs/lib/trivial.nix:334:42

nix-repl> lib.generators.toPretty {} (builtins.foldl' (a: b: a + b))
error: 'functionArgs' requires a function, at /home/lukas/src/nix/nixpkgs/lib/trivial.nix:334:42

I'm pretty sure this qualifies as a nix bug and should be filed
accordingly, but we can work around it in lib.generators.toPretty by
using tryEval and falling back to {} which functionArgs _should_ return
for builtins.

The nix behavior is inconsistent to say the least:

nix-repl> builtins.functionArgs builtins.functionArgs
error: 'functionArgs' requires a function, at (string):1:1

nix-repl> builtins.typeOf builtins.functionArgs
"lambda"

builtins.functionArgs (a: 1 + a)
{ }

nix-repl> builtins.typeOf (a: 1 + a)
"lambda"

too, such as FreeBSD (as of v13) and Gentoo (as of late 2020).

Since we use musl extensively, let's default to ELFv2.

Nix gives us the power to specify this declaratively for the entire
system, so ELFv1 is not dropped entirely. It can be specified explicitly
in the target config, e.g. "powerpc64-unknown-linux-elfv1". Otherwise the
default is "powerpc64-unknown-linux-elfv2". For musl,
"powerpc64-unknown-linux-musl" must use elfv2 internally to function.

lib/types: Improved functionTo merging
Now type checks the resulting function values and allows mkMerge and co.
Also indicates that the type check is done in the function body

41e13149f7 lib/debug: add traceFnSeqN
Immensely helpful when you want to see the changes a function makes to
its value as it passes through.

Example:

```
$ nix-instantiate --strict --eval -E '(with import ./lib; traceFnSeqN 2 "id" (x: x) { a.b.c = 3; })'
trace: {
  fn = "id";
  from = {
    a = {
      b = {…};
    };
  };
  to = {
    a = {
      b = {…};
    };
  };
}
{ a = { b = { c = 3; }; }; }
```
