Couldn't extend types.uniq and it had a silly name anyway.
Now we can have better error messages.

Jules Aguillon 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).

sternenseemann 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.

Jules Aguillon f25a13212b types.singleLineStr: Disallow \r 2022-01-18 23:56:50 +01:00
Jules Aguillon 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.

pennae 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.

pennae 0de4ecff8c lib/modules: extract multiply-used value in byName
module.${attr} is used at least twice, so it must be evaluated at least
twice (and since it's a function argument, be turned into a thunk
twice).

polykernel 63ce7d3184 lib/attrset: miscellaneous optimizations
- Eta reduce `mapAttrsRecursiveCond`, `foldAttrs`, `getAttrFromPath`.
- Modify `matchAttrs` to use `elemAt` instead of `head (tail xs)` to access
  elements.
- Modify `matchAttrs` to use `any id` instead of `foldr and true`.

polykernel a54f2231c9 lib/attrset: optimize element access in recursiveUpdateUntil
- 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.

pennae 2dcae7d82f lib/attrsets: use builtins.zipAttrsWith if available 2021-12-25 15:20:26 +01:00
pennae 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.

sternenseemann 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.

lib: fix flake check
`builtins.currentSystem` is not available in pure eval. For this
particular test, we don't really care since it's all about generating

Victor Engmark 989f034ff1 lib/tests: Set hardening pragmas
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
  it at that point.
- 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
  expression.
