$ nix repl lib
Welcome to Nix version 2.0.2. Type :? for help.
Loading 'lib'...
Added 350 variables.
-- this is the exact example from the function's documentation:
nix-repl> recursiveUpdateUntil (path: l: r: path == ["foo"]) {
# first attribute set
foo.bar = 1;
foo.baz = 2;
bar = 3;
} {
#second attribute set
foo.bar = 1;
foo.quz = 2;
baz = 4;
}
{ bar = 3; baz = 4; foo = { bar = 1; baz = 2; quz = 2; }; }
-- although the documentation says:
{
foo.bar = 1; # 'foo.*' from the second set
foo.quz = 2; #
bar = 3; # 'bar' from the first set
baz = 4; # 'baz' from the second set
}
binutils expects x86_64-unknown-netbsd<version> (only 3 parts!). Any other combo seems to fail.
Also handle darwin versions similarly.

* The ELK stack is upgraded to 6.3.2.
* `elasticsearch6`, `logstash6` and `kibana6` now come with X-Pack which is
a suite of additional features. These are however licensed under the unfree
"Elastic License".
* Fortunately they also provide OSS versions which are now packaged
under: `elasticsearch6-oss`, `logstash6-oss` and `kibana6-oss`.
Note that the naming of the attributes is consistent with upstream.
* The test `nix-build nixos/tests/elk.nix -A ELK-6` will test the OSS
version by default. You can also run the test on the unfree ELK using:
`NIXPKGS_ALLOW_UNFREE=1 nix-build nixos/tests/elk.nix -A ELK-6 --arg enableUnfree true`
Nix now supports floats & we can pretty easily map them to Plist’s
<real></real> type. Note that I am unsure how this affects older
version of Nix that may or may not have builtins.isFloat available.
Make sure this satisfies minver.nix’s "1.11" requirement.
Instead of using a string to describe kernel config, use a nix
attribute set, then converted to a string.
- allows to override the config, aka convert 'yes' into 'modules' or
vice-versa
- while for now merging different configs is still crude (last spec wins),
at least there should be only one CONFIG_XYZ value compared to the current string
config where the first defined would be used and others ignored.
[initial idea by copumpkin in 2016, a major rebase to 2018 by teto]
It wasn’t exactly clear which NDK you were using previously. This adds
an attribute to system that handles what version of the NDK we should
use when building things.

Before this change `mkRenamedOptionModule` would override option defaults
even when the old option name is left unused. For instance
```nix
{
optios = {
services.name.new = mkOption {
default = { one = {}; };
};
};
imports = [
(mkRenamedOptionModule [ "services" "name" "old" ] [ "services" "name" "new" "two" ])
];
config = {};
}
```
would evaluate to
`{ config.services.name.new = { two = {}; }; }`
when you'd expect it to evaluate to
`{ config.services.name.new = { one = {}; }; }`.
In particular, now the mainline kernel can be built on the RPi 1 as well
(so kernelBaseConfig should always be a mainline defconfig from now on).
And RPi 2 users can now use linux_rpi without doing the
`nixpkgs.config.platform = lib.systems.platforms.raspberrypi2;` dance.
toPath has confusing semantics and is never necessary; it can always
either just be omitted or replaced by pre-concatenating `/.`. It has
been marked as "!!! obsolete?" for more than 10 years in a C++
comment, hopefully removing it will let us properly deprecate and,
eventually, remove it.
There are two different official variations which differ in their float
support, so such a blanket statement is invalid.
`lib.systems.platforms.*android` already handles each case correctly.
Correcting an error in 827ef09140.
ARM ABIs now have a float field. This is used as a fallback to lessen
our use of `platform.gcc.float`. I didn't know what the MIPs convention
is so I kept using `platform.gcc.float` in that case.
Assigning a list of 10 or more elements to an option having the type
`loaOf a` produces a configuration value that is not honoring the
order of the original list. This commit fixes this and a related issue
arising when 10 or more lists are merged into this type of option.
Without this change
(coercedTo str toInt int).check "foo"
would evaluate to true, even though
(coercedTo str toInt int).merge {} [{ value = "foo"; }]
will throw an error because "foo" can't be coerced to an int.
The commented-out configs are @shlevy's old known-good ones. I changed
them as needed to play nice with lib.systems.parse but did not test so
leaving them as comments for now.
As suggested in https://github.com/NixOS/nixpkgs/pull/39416#discussion_r183845745
the versioning attributes in `lib` should be consistent to
`nixos/version` which implicates the following changes:
* `lib.trivial.version` -> `lib.trivial.release`
* `lib.trivial.suffix` -> `lib.trivial.versionSuffix`
* `lib.nixpkgsVersion` -> `lib.version`
As `lib.nixpkgsVersion` is referenced several times in `NixOS/nixpkgs`,
`NixOS/nix` and probably several user's setups. As the rename will cause
a notable impact it's better to keep `lib.nixpkgsVersion` as alias with
a warning yielded by `builtins.trace`.
The function isn’t used anywhere and `addErrorContext` is an undocumented
builtin.
The builtin is explicitely qualified at its two uses in the module system.
`attrNamesToStr` is very specific (and pretty trivial), so it doesn’t make sense
to have it in the library.
`traceXMLVal(Marked)` are just a builtin and `trace` and not very useful in
general (trace output should not be parsed anyway).
Following legacy packing conventions, `isArm` was defined just for
32-bit ARM instruction set. This is confusing to non packagers though,
because Aarch64 is an ARM instruction set.
The official ARM overview for ARMv8[1] is surprisingly not confusing,
given the overall state of affairs for ARM naming conventions, and
offers us a solution. It divides the nomenclature into three levels:
```
ISA: ARMv8 {-A, -R, -M}
/ \
Mode: Aarch32 Aarch64
| / \
Encoding: A64 A32 T32
```
At the top is the overall v8 instruction set archicture. Second are the
two modes, defined by bitwidth but differing in other semantics too, and
buttom are the encodings, (hopefully?) isomorphic if they encode the
same mode.
The 32 bit encodings are mostly backwards compatible with previous
non-Thumb and Thumb encodings, and if so we can pun the mode names to
instead mean "sets of compatable or isomorphic encodings", and then
voilà we have nice names for 32-bit and 64-bit arm instruction sets
which do not use the word ARM so as to not confused either laymen or
experienced ARM packages.

This allows the lib fixed point to be extended with
myLib = lib.extend (self: super: {
foo = "foo";
})
With this it's possible to have the new modified lib attrset available to all
modules when using evalModules
myLib.evalModules {
modules = [ ({ lib, ... }: {
options.bar = lib.mkOption {
default = lib.foo;
};
}) ];
}
=> { config = { bar = "foo"; ... }; options = ...; }
- `localSystem` is added, it strictly supercedes system
- `crossSystem`'s description mentions `localSystem` (and vice versa).
- No more weird special casing I don't even understand
TEMP
So far, `mkValueString` defaulted to `toString`,
which is a bad match for most configuration file formats,
especially because how booleans are formatted.
This also improves error messages for unsupported types.
Add a test to codify the formatting.
The isSeccomputable flag treated Linux without seccomp as just a
normal variant, when it really should be treated as a special case
incurring complexity debt to support.
The isKexecable flag treated Linux without kexec as just a normal
variant, when it really should be treated as a special case incurring
complexity debt to support.
Uses the HTTPS url for cases where the existing URL has a permanent
redirect. For each domain, at least one fixed derivation URL was
downloaded to test the domain is properly serving downloads.
Also fixes jbake source URL, which was broken.
Otherwise obscure cross-compilations are hampered. `all` breaks all but
the initial derivation (which we can't even write yet) in an open world
setting however, so we really shouldn't have it.
I noticed LLVM accepts `ios` as its own OS in platform triples; a
recent change as far as I know. I see it also accepts `macos*` for macOS
(formerly OS X). If it's now customary to distinguish iOS like so
(rather than guessing from the aarch, lets add both so our OSes are
still disjoint, and make Darwin a family instead.
But changing the config everywhere would probably be a mass rebuild, and
I'm not sure how well other software supports OSes besides "darwin", so
I'm keeping that the default name for macOS for now.
First, we need check against the host platform, not the build platform.
That's simple enough.
Second, we move away from exahustive finite case analysis (i.e.
exhaustively listing all platforms the package builds on). That only
work in a closed-world setting, where we know all platforms we might
build one. But with cross compilation, we may be building for arbitrary
platforms, So we need fancier filters. This is the closed world to open
world change.
The solution is instead of having a list of systems (strings in the form
"foo-bar"), we have a list of of systems or "patterns", i.e. attributes
that partially match the output of the parsers in `lib.systems.parse`.
The "check meta" logic treats the systems strings as an exact whitelist
just as before, but treats the patterns as a fuzzy whitelist,
intersecting the actual `hostPlatform` with the pattern and then
checking for equality. (This is done using `matchAttrs`).
The default convenience lists for `meta.platforms` are now changed to be
lists of patterns (usually a single pattern) in
`lib/systems/for-meta.nix` for maximum flexibility under this new
system.
Fixes#30902
Negative reasoning like `allBut` is a bad idea with an open world of
platforms. Concretely, if we add a new, quite different sort of
platform, existing packages with `allBut` will claim they work on it
even though they probably won't.
Handle the case where options have funny symbols inside of them.
Example:
If I reference the following attribute without it being defined:
security.acme.certs."example.com".webroot
I now get the error:
The option `security.acme.certs."example.com".webroot' is used but
not defined.
where before I got:
The option `security.acme.certs.example.com.webroot' is used but
not defined.
which is not true.
Based on a request by @oxij:
“Can we also rename this file to `maintainers/maintainers-list.nix` while we at
this? Motivation: much saner `git log ./lib`.”
Corrected every handle that had no commits to nixpkgs, manually researched the
correct handles by looking at maintained packages & blames/history on Github.
Based on https://github.com/NixOS/nixpkgs/pull/34842, the
nix-instantiate output was pretty-printed and the validity of the github handles
manually verified, by automatically checking whether the user handles exist on
github (https://github.com/userhandle, status 200 or 404).
Each handle under 5 characters was manually checked (because the collision
probability with non-maintainer accounts is high), each missing entry was
manually researched.
The script used is kept in `maintainers/scripts` as an example of how to work
with the mainainers list through nix’ JSON interface.
All 5 daemon types can be enabled and configured through the module and the module both creates the ceph.conf required but also creates and enables specific services for each daemon, based on the systemd service files that upstream provides.
Existing "mips64el" should be "mipsel".
This is just the barest minimum so that nixpkgs can recognize them as
systems - although required for building individual derivations onto
MIPS boards, it is not sufficient if you want to actually build nixos on
those targets
