Since 40e7be1 all ARM platforms that didn't have a parsed cpu version
(e.g. arm-none-eabi) would be handled as armv7l-hf-multiplatform which
did break building arm-trusted-platform packages for some targets (e.g.
rk3399).
Using pcBase as fallback, instead of armv7l-hf-multiplatform,
corresponds with the behaviour we had before 40e7be1.
We recently switched to more explicit GPL license names in line
with the SPDX change and GNU Foundation recommendations:
https://www.gnu.org/licenses/identify-licenses-clearly.html
This followed up older change to use the recommended SPDX ID
18a5e8c36b
but using the `-only` variant for these deprecated licenses too
makes it harder to check for them automatically.
Let’s switch to the appropriate SPDX ID again.
Previously the .enable option was used to encode the condition as well,
which lead to some oddness:
- In order to encode an assertion, one had to invert it
- To disable a check, one had to mkForce it
By introducing a separate .check option this is solved because:
- It can be used to encode assertions
- Disabling is done separately with .enable option, whose default can be
overridden without a mkForce
Previously this option was thought to be necessary to avoid infinite
recursion, but it actually isn't, since the check evaluation isn't fed
back into the module fixed-point.
This implements assertions/warnings supported by the module system directly,
instead of just being a NixOS option (see
nixos/modules/misc/assertions.nix).
This has the following benefits:
- It allows cleanly redoing the user interface. The new
implementation specifically allows disabling assertions or
converting them to warnings instead.
- Assertions/warnings can now be thrown easily from within
submodules, which previously wasn't possible and needed workarounds.
Initially https://github.com/NixOS/nixpkgs/pull/82897 prevented
non-visible options from being rendered in the manual, but
visible-but-internal options were still being recursed into. This fixes
this, aligning the recurse condition here with the one in
make-options-doc/default.nix
The last use of `kernelMajor` in Nixpkgs was removed in 2018.
Even then, I'm not positive it was actually in an exercised code path.
AFAIUI this is now totally redundant and useless as it really was meant
for the 2.4 -> 2.6 transition.
split comes from builtins, not lib.
error: attribute 'split' missing, at /nix/path/nixpkgs/lib/sources.nix:4:4
(use '--show-trace' to show detailed location information)
I think there was a silent (i.e. semantic) merge conflict between PR #101139 and
PR #100456. This commit should fix the error, which manifests as follows:
error: undefined variable 'boolToString' at /home/kkini/src/nixpkgs/lib/types.nix:552:42
Nix can perform static scope checking, but whenever code is inside
a `with` expression, the analysis breaks down, because it can't
know statically what's in the attribute set whose attributes were
brought into scope. In those cases, Nix has to assume that
everything works out.
Except it doesnt. Removing `with` from lib/ revealed an undefined
variable in an error message.
If that doesn't convince you that we're better off without `with`,
I can tell you that this PR results in a 3% evaluation performance
improvement because Nix can look up local variables by index.
This adds up with applications like the module system.
Furthermore, removing `with` makes the binding site of each
variable obvious, which helps with comprehension.
Add a friendly function to easily return a flattened list of files
within a directory.
This is useful if you want to easily iterate or concatSep the list of
files all found within a directory.
(i.e. when constructing Java's CLASSPATH)

Previously if `_file` was specified by a module:
trace: warning: The type `types.string' of option `foo' defined in `/nix/store/yxhm2il5yrb92fldgriw0wyqh2kk9qyc-bug.nix' is deprecated. See https://github.com/NixOS/nixpkgs/pull/66346 for better alternative types.
With this change:
trace: warning: The type `types.string' of option `foo' defined in `/home/infinisil/src/nixpkgs/bug.nix' is deprecated. See https://github.com/NixOS/nixpkgs/pull/66346 for better alternative types.
If multiple definitions are passed, this evaluates them all as if they
were the only one, for a better error message. In particular this won't
show module-internal properties like `_type = "override"` and co.
- These symbols can be confusing for those not familiar with them
- There's no harm in making these more obvious
- Terminals may not print them correctly either
Also changes the function argument printing slightly to be more obvious
This new type has unsurprising merge behavior: Only attribute sets are
merged together (recursively), and only if they don't conflict.
This is in contrast to the existing types:
- types.attrs is problematic because later definitions completely
override attributes of earlier definitions, and it doesn't support
mkIf and co.
- types.unspecified is very similar to types.attrs, but it has smart
merging behavior that often doesn't make sense, and it doesn't support
all types
