// '/foo/bar/baz.html'.split('/') -> [ '', 'foo', 'bar', 'baz.html' ]

# Automatic and Optionally Enforced Determinism Verification
|

|

Automatically verify every build at build time by executing the build

||||
|

Setting `repeat` and `enforce-determinism` in your `nix.conf` permits
|

the automated verification of every build Nix performs.
|

require the build to be deterministic:
|

|
||||
enforce-determinism = true
|
||||
repeat = 2
|

|

Setting `enforce-determinism` to false as in the following

configuration will run the build multiple times, execute the build

hook, but will allow the build to succeed even if it does not build

# Architecture
|
||||
|
||||
This chapter describes how Nix works.
|
||||
It should help users understand why Nix behaves as it does, and it should help developers understand how to modify Nix and how to write similar tools.
|
||||
|
||||
## Overview
|
||||
|
||||
Nix consists of [hierarchical layers].
|
||||
|
||||

|
||||
|
||||
The following [concept map] shows its main components (rectangles), the objects they operate on (rounded rectangles), and their interactions (connecting phrases):

At the top is the [command line interface](../command-ref/command-ref.md) that drives the underlying layers.
|
||||
|
||||
The [Nix language](../language/index.md) evaluator transforms Nix expressions into self-contained *build plans*, which are used to derive *build results* from referenced *build inputs*.
|
||||
|
||||
The command line interface and Nix expressions are what users deal with most.
|
||||
|
||||
> **Note**
|
||||
> The Nix language itself does not have a notion of *packages* or *configurations*.
|
||||
> As far as we are concerned here, the inputs and results of a build plan are just data.
|
||||
|
||||
Underlying the command line interface and the Nix language evaluator is the [Nix store](../glossary.md#gloss-store), a mechanism to keep track of build plans, data, and references between them.
|
||||
It can also execute build plans to produce new data, which are made available to the operating system as files.
|
||||
|
||||
A build plan itself is a series of *build tasks*, together with their build inputs.
|
||||
|
||||
> **Important**
|
||||
> A build task in Nix is called [derivation](../glossary#gloss-derivation).
|
||||
|
||||
Each build task has a special build input executed as *build instructions* in order to perform the build.
|
||||
The result of a build task can be input to another build task.
|
||||
|
||||
The following [data flow diagram] shows a build plan for illustration.
|
||||
Build inputs used as instructions to a build task are marked accordingly:

instance, the value

|

|
||||
will cause Nix to look for paths relative to `/home/eelco/Dev` and
|
||||
`/etc/nixos`, in this order. It is also possible to match paths

against a prefix. For example, the value
|
||||
|

nixpkgs=/home/eelco/Dev/nixpkgs-branch:/etc/nixos
|
||||

will cause Nix to search for `<nixpkgs/path>` in

`https://`, it is interpreted as the URL of a tarball that will be

The URLs of the tarballs from the official nixos.org channels (see

### Functional tests
|
||||
|
||||
The functional tests reside under the `tests` directory and are listed in `tests/local.mk`.
|
||||
The whole testsuite can be run with `make install && make installcheck`.
|
||||
Individual tests can be run with `make tests/{testName}.sh.test`.
|
||||
Each test is a bash script.
|
||||
|
||||
The whole test suite can be run with:
|
||||
|
||||
```shell-session
|
||||
$ make install && make installcheck
|
||||
ran test tests/foo.sh... [PASS]
|
||||
ran test tests/bar.sh... [PASS]
|
||||
...
|
||||
```
|
||||
|
||||
Individual tests can be run with `make`:
|
||||
|
||||
```shell-session
|
||||
$ make tests/${testName}.sh.test
|
||||
ran test tests/${testName}.sh... [PASS]
|
||||
```
|
||||
|
||||
or without `make`:
|
||||
|
||||
```shell-session
|
||||
$ ./mk/run-test.sh tests/${testName}.sh
|
||||
ran test tests/${testName}.sh... [PASS]
|
||||
```
|
||||
|
||||
To see the complete output, one can also run:
|
||||
|
||||
```shell-session
|
||||
$ ./mk/debug-test.sh tests/${testName}.sh
|
||||
+ foo
|
||||
output from foo
|
||||
+ bar
|
||||
output from bar
|
||||
...
|
||||
```
|
||||
|
||||
The test script will then be traced with `set -x` and the output displayed as it happens, regardless of whether the test succeeds or fails.
|
||||
|
||||
#### Debugging failing functional tests
|
||||
|
||||
When a functional test fails, it usually does so somewhere in the middle of the script.
|
||||
|
||||
To figure out what's wrong, it is convenient to run the test regularly up to the failing `nix` command, and then run that command with a debugger like GDB.
|
||||
|
||||
For example, if the script looks like:
|
||||
|
||||
```bash
|
||||
foo
|
||||
nix blah blub
|
||||
bar
|
||||
```
|
||||
edit it like so:
|
||||
|
||||
```diff
|
||||
foo
|
||||
-nix blah blub
|
||||
+gdb --args nix blah blub
|
||||
bar
|
||||
```
|
||||
|
||||
Then, running the test with `./mk/debug-test.sh` will drop you into GDB once the script reaches that point:
|
||||
|
||||
```shell-session
|
||||
$ ./mk/debug-test.sh tests/${testName}.sh
|
||||
...
|
||||
+ gdb blash blub
|
||||
GNU gdb (GDB) 12.1
|
||||
...
|
||||
(gdb)
|
||||
```
|
||||
|
||||
One can debug the Nix invocation in all the usual ways.
|
||||
For example, enter `run` to start the Nix invocation.

# String interpolation
|
||||
|
||||
String interpolation is a language feature where a [string], [path], or [attribute name] can contain expressions enclosed in `${ }` (dollar-sign with curly brackets).
|
||||
|
||||
Such a string is an *interpolated string*, and an expression inside is an *interpolated expression*.
|
||||
|
||||
Interpolated expressions must evaluate to one of the following:
|
||||
|
||||
- a [string]
|
||||
- a [path]
|
||||
- a [derivation]
|
||||
|
||||
[string]: ./values.md#type-string
|
||||
[path]: ./values.md#type-path
|
||||
[attribute name]: ./values.md#attribute-set
|
||||
[derivation]: ../glossary.md#gloss-derivation
|
||||
|
||||
## Examples
|
||||
|
||||
### String
|
||||
|
||||
Rather than writing
|
||||
|
||||
```nix
|
||||
"--with-freetype2-library=" + freetype + "/lib"
|
||||
```
|
||||
|
||||
(where `freetype` is a [derivation]), you can instead write
|
||||
|
||||
```nix
|
||||
"--with-freetype2-library=${freetype}/lib"
|
||||
```
|
||||
|
||||
The latter is automatically translated to the former.
|
||||
|
||||
A more complicated example (from the Nix expression for [Qt](http://www.trolltech.com/products/qt)):
|
||||
|
||||
```nix
|
||||
configureFlags = "
|
||||
-system-zlib -system-libpng -system-libjpeg
|
||||
${if openglSupport then "-dlopen-opengl
|
||||
-L${mesa}/lib -I${mesa}/include
|
||||
-L${libXmu}/lib -I${libXmu}/include" else ""}
|
||||
${if threadSupport then "-thread" else "-no-thread"}
|
||||
";
|
||||
```
|
||||
|
||||
Note that Nix expressions and strings can be arbitrarily nested;
|
||||
in this case the outer string contains various interpolated expressions that themselves contain strings (e.g., `"-thread"`), some of which in turn contain interpolated expressions (e.g., `${mesa}`).
|
||||
|
||||
### Path
|
||||
|
||||
Rather than writing
|
||||
|
||||
```nix
|
||||
./. + "/" + foo + "-" + bar + ".nix"
|
||||
```
|
||||
|
||||
or
|
||||
|
||||
```nix
|
||||
./. + "/${foo}-${bar}.nix"
|
||||
```
|
||||
|
||||
you can instead write
|
||||
|
||||
```nix
|
||||
./${foo}-${bar}.nix
|
||||
```
|
||||
|
||||
### Attribute name
|
||||
|
||||
Attribute names can be created dynamically with string interpolation:
|
||||
|
||||
```nix
|
||||
let name = "foo"; in
|
||||
{
|
||||
${name} = "bar";
|
||||
}
|
||||
```
|
||||
|
||||
{ foo = "bar"; }

|
|||
returns and tabs can be written as `\n`, `\r` and `\t`,
|
||||
respectively.
|
||||
|
||||
You can include the result of an expression into a string by
|
||||
enclosing it in `${...}`, a feature known as *antiquotation*. The
|
||||
enclosed expression must evaluate to something that can be coerced
|
||||
into a string (meaning that it must be a string, a path, or a
|
||||
derivation). For instance, rather than writing
|
||||
You can include the results of other expressions into a string by enclosing them in `${ }`, a feature known as [string interpolation].
|
||||
|
||||
```nix
|
||||
"--with-freetype2-library=" + freetype + "/lib"
|
||||
```
|
||||
|
||||
(where `freetype` is a derivation), you can instead write the more
|
||||
natural
|
||||
|
||||
```nix
|
||||
"--with-freetype2-library=${freetype}/lib"

Antiquotation is supported in any paths except those in angle brackets.
|

`./${foo}-${bar}.nix` is a more convenient way of writing
|
||||
`./. + "/" + foo + "-" + bar + ".nix"` or `./. + "/${foo}-${bar}.nix"`. At
|

least one slash must appear *before* any antiquotations for this to be
|

recognized as a path. `a.${foo}/b.${bar}` is a syntactically valid division
|
||||
operation. `./a.${foo}/b.${bar}` is a path.
|
||||
When an [interpolated string][string interpolation] evaluates to a path, the path is first copied into the Nix store and the resulting string is the [store path] of the newly created [store object].

[store path]: ../glossary.md#gloss-store-path

[store object]: ../glossary.md#gloss-store-object
|

For instance, evaluating `"${./foo.txt}"` will cause `foo.txt` in the current directory to be copied into the Nix store and result in the string `"/nix/store/<hash>-foo.txt"`.
|
||||
|
||||
Note that the Nix language assumes that all input files will remain _unchanged_ while evaluating a Nix expression.
|
||||
For example, assume you used a file path in an interpolated string during a `nix repl` session.
|
||||
Later in the same session, after having changed the file contents, evaluating the interpolated string with the file path again might not return a new store path, since Nix might not re-read the file contents.
|
||||
|
||||
Paths themselves, except those in angle brackets (`< >`), support [string interpolation].

At least one slash (`/`) must appear *before* any interpolated expression for the result to be recognized as a path.

|

{ "$!@#?" = 123; }."$!@#?"
|
||||
```
|
||||
|

This will evaluate to `123` (Assuming `bar` is antiquotable). In the

can be dropped:
|

|

let bar = "bar";
|

{ "foo ${bar}" = 123; }."foo ${bar}"
|

```
|

|

This will evaluate to `123` if `bar` evaluates to `"foo"` when coerced
|
||||
to a string and `456` otherwise (again assuming `bar` is antiquotable).
|

Both will evaluate to `123`.
|

Attribute names support [string interpolation]:

Both will evaluate to `123`.

# Release 2.12 (2022-12-06)
|
||||
|
||||
* On Linux, Nix can now run builds in a user namespace where they run
|
||||
as root (UID 0) and have 65,536 UIDs available.
|
||||
<!-- FIXME: move this to its own section about system features -->
|
||||
This is primarily useful for running containers such as `systemd-nspawn`
|
||||
inside a Nix build. For an example, see [`tests/systemd-nspawn/nix`][nspawn].
|
||||
|
||||
[nspawn]: https://github.com/NixOS/nix/blob/67bcb99700a0da1395fa063d7c6586740b304598/tests/systemd-nspawn.nix.
|
||||
|
||||
A build can enable this by setting the derivation attribute:
|
||||
|
||||
```
|
||||
requiredSystemFeatures = [ "uid-range" ];
|
||||
```
|
||||
|
||||
The `uid-range` [system feature] requires the [`auto-allocate-uids`]
|
||||
setting to be enabled.
|
||||
|
||||
[system feature]: ../command-ref/conf-file.md#conf-system-features
|
||||
|
||||
* Nix can now automatically pick UIDs for builds, removing the need to
|
||||
create `nixbld*` user accounts. See [`auto-allocate-uids`].
|
||||
|
||||
[`auto-allocate-uids`]: ../command-ref/conf-file.md#conf-auto-allocate-uids
|
||||
|
||||
* On Linux, Nix has experimental support for running builds inside a
|
||||
cgroup. See
|
||||
[`use-cgroups`](../command-ref/conf-file.md#conf-use-cgroups).
|
||||
|
||||
* `<nix/fetchurl.nix>` now accepts an additional argument `impure` which
|
||||
defaults to `false`. If it is set to `true`, the `hash` and `sha256`
|
||||
arguments will be ignored and the resulting derivation will have
|
||||
`__impure` set to `true`, making it an impure derivation.
|
||||
|
||||
* If `builtins.readFile` is called on a file with context, then only
|
||||
the parts of the context that appear in the content of the file are
|
||||
retained. This avoids a lot of spurious errors where strings end up
|
||||
having a context just because they are read from a store path
|
||||
([#7260](https://github.com/NixOS/nix/pull/7260)).
|
||||
|
||||
* `nix build --json` now prints some statistics about top-level
|
||||
derivations, such as CPU statistics when cgroups are enabled.

|
||||
* The `repeat` and `enforce-determinism` options have been removed
|
||||
since they had been broken under many circumstances for a long time.
|
||||
|
||||
* You can now use [flake references] in the [old command line interface], e.g.
|
||||
|
||||
[flake references]: ../command-ref/new-cli/nix3-flake.md#flake-references

# NIX_PATH=nixpkgs=flake:nixpkgs nix-build '<nixpkgs>' -A hello
|
||||
```
|
||||
|
||||
* Instead of "antiquotation", the more common term [string interpolation](../language/string-interpolation.md) is now used consistently.
|
||||
Historical release notes were not changed.
|
||||
|
||||
* Error traces have been reworked to provide detailed explanations and more
|
||||
accurate error locations. A short excerpt of the trace is now shown by
|
||||
default when an error occurs.

# Nix maintainers team
|
||||
|
||||
## Motivation
|
||||
|
||||
The goal of the team is to help other people to contribute to Nix.
|
||||
|
||||
## Members
|
||||
|
||||
- Eelco Dolstra (@edolstra) – Team lead
|
||||
- Théophane Hufschmitt (@thufschmitt)
|
||||
- Valentin Gagarin (@fricklerhandwerk)
|
||||
- Thomas Bereknyei (@tomberek)
|
||||
- Robert Hensing (@roberth)
|
||||
|
||||
## Meeting protocol
|
||||
|
||||
The team meets twice a week:
|
||||
|
||||
- Discussion meeting: [Fridays 13:00-14:00 CET](https://calendar.google.com/calendar/event?eid=MHNtOGVuNWtrZXNpZHR2bW1sM3QyN2ZjaGNfMjAyMjExMjVUMTIwMDAwWiBiOW81MmZvYnFqYWs4b3E4bGZraGczdDBxZ0Bn)
|
||||
|
||||
1. Triage issues and pull requests from the _No Status_ column (30 min)
|
||||
2. Discuss issues and pull requests from the _To discuss_ column (30 min)
|
||||
|
||||
- Work meeting: [Mondays 13:00-15:00 CET](https://calendar.google.com/calendar/event?eid=NTM1MG1wNGJnOGpmOTZhYms3bTB1bnY5cWxfMjAyMjExMjFUMTIwMDAwWiBiOW81MmZvYnFqYWs4b3E4bGZraGczdDBxZ0Bn)
|
||||
|
||||
1. Code review on pull requests from _In review_.
|
||||
2. Other chores and tasks.
|
||||
|
||||
Meeting notes are collected on a [collaborative scratchpad](https://pad.lassul.us/Cv7FpYx-Ri-4VjUykQOLAw), and published on Discourse under the [Nix category](https://discourse.nixos.org/c/dev/nix/50).
|
||||
|
||||
## Project board protocol
|
||||
|
||||
The team uses a [GitHub project board](https://github.com/orgs/NixOS/projects/19/views/1) for tracking its work.
|
||||
|
||||
Issues on the board progress through the following states:
|
||||
|
||||
- No Status
|
||||
|
||||
Team members can add pull requests or issues to discuss or review together.
|
||||
|
||||
During the discussion meeting, the team triages new items.
|
||||
If there is disagreement on the general idea behind an issue or pull request, it is moved to _To discuss_, otherwise to _In review_.
|
||||
|
||||
- To discuss
|
||||
|
||||
Pull requests and issues that are important and controversial are discussed by the team during discussion meetings.
|
||||
|
||||
This may be where the merit of the change itself or the implementation strategy is contested by a team member.
|
||||
|
||||
- In review
|
||||
|
||||
Pull requests in this column are reviewed together during work meetings.
|
||||
This is both for spreading implementation knowledge and for establishing common values in code reviews.
|
||||
|
||||
When the overall direction is agreed upon, even when further changes are required, the pull request is assigned to one team member.
|
||||
|
||||
- Assigned for merging
|
||||
|
||||
One team member is assigned to each of these pull requests.
|
||||
They will communicate with the authors, and make the final approval once all remaining issues are addressed.
|
||||
|
||||
If more substantive issues arise, the assignee can move the pull request back to _To discuss_ to involve the team again.
|
||||
|
||||
The process is illustrated in the following diagram:

Add *path* to the Nix search path. The Nix search path is
|
||||
initialized from the colon-separated [`NIX_PATH`](./env-common.md#env-NIX_PATH) environment
|
||||
variable, and is used to look up the location of Nix expressions using [paths](../language/values.md#type-path) enclosed in angle
|
||||
brackets (i.e., `<nixpkgs>`).
|
||||
|
||||
For instance, passing
|
||||
|
||||
```
|
||||
-I /home/eelco/Dev
|
||||
-I /etc/nixos
|
||||
```
|
||||
|
||||
will cause Nix to look for paths relative to `/home/eelco/Dev` and
|
||||
`/etc/nixos`, in that order. This is equivalent to setting the
|
||||
`NIX_PATH` environment variable to
|
||||
|
||||
```
|
||||
/home/eelco/Dev:/etc/nixos
|
||||
```
|
||||
|
||||
It is also possible to match paths against a prefix. For example,
|
||||
passing
|
||||
|
||||
```
|
||||
-I nixpkgs=/home/eelco/Dev/nixpkgs-branch
|
||||
-I /etc/nixos
|
||||
```
|
||||
|
||||
will cause Nix to search for `<nixpkgs/path>` in
|
||||
`/home/eelco/Dev/nixpkgs-branch/path` and `/etc/nixos/nixpkgs/path`.
|
||||
|
||||
If a path in the Nix search path starts with `http://` or `https://`,
|
||||
it is interpreted as the URL of a tarball that will be downloaded and
|
||||
unpacked to a temporary location. The tarball must consist of a single
|
||||
top-level directory. For example, passing
|
||||
|
||||
```
|
||||
-I nixpkgs=https://github.com/NixOS/nixpkgs/archive/master.tar.gz
|
||||
```
|
||||
|
||||
tells Nix to download and use the current contents of the `master`
|
||||
branch in the `nixpkgs` repository.
|
||||
|
||||
The URLs of the tarballs from the official `nixos.org` channels
|
||||
(see [the manual page for `nix-channel`](../nix-channel.md)) can be
|
||||
abbreviated as `channel:<channel-name>`. For instance, the
|
||||
following two flags are equivalent:
|
||||
|
||||
```
|
||||
-I nixpkgs=channel:nixos-21.05
|
||||
-I nixpkgs=https://nixos.org/channels/nixos-21.05/nixexprs.tar.xz
|
||||
```
|
||||
|
||||
You can also fetch source trees using [flake URLs](./nix3-flake.md#url-like-syntax) and add them to the
|
||||
search path. For instance,
|
||||
|
||||
```
|
||||
-I nixpkgs=flake:nixpkgs
|
||||
```
|
||||
|
||||
specifies that the prefix `nixpkgs` shall refer to the source tree
|
||||
downloaded from the `nixpkgs` entry in the flake registry. Similarly,
|
||||
|
||||
```
|
||||
-I nixpkgs=flake:github:NixOS/nixpkgs/nixos-22.05
|
||||
```
|
||||

||||

||||
`NixOS/nixpkgs` repository on GitHub.

// like they would with the current naive `find`.
