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

# Architecture

*(This chapter is unstable and a work in progress. Incoming links may rot.)*
|
||||
|
||||
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][layer-architecture].

At the top is the [command line interface](../command-ref/command-ref.md), translating from invocations of Nix executables to interactions with the underlying layers.
|
||||
At the top is the [command line interface](../command-ref/command-ref.md) that drives the underlying layers.
|
||||
|
||||
Below that is the [Nix expression language](../expressions/expression-language.md), a [purely functional][purely-functional-programming] configuration language.
|
||||
It is used to compose expressions which ultimately evaluate to self-contained *build plans*, used to derive *build results* from referenced *build inputs*.
|
||||
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 and Nix language are what users interact with most.

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 these is the [Nix store](./store/store.md), a mechanism to keep track of build plans, data, and references between them.
|
||||
It can also execute build plans to produce new 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 is a series of *build tasks*.
|
||||
Each build task has a special build input which is used as *build instructions*.
|
||||
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.md#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:

# File System Object
|
||||
|
||||
The Nix store uses a simple file system model for the data it holds in [store objects](store.md#store-object).
|
||||
|
||||
Every file system object is one of the following:
|
||||
|
||||
- File: an executable flag, and arbitrary data for contents
|
||||
- Directory: mapping of names to child file system objects
|
||||
- [Symbolic link][symlink]: may point anywhere.
|
||||
|
||||
We call a store object's outermost file system object the *root*.
|
||||
|
||||
data FileSystemObject
|
||||
= File { isExecutable :: Bool, contents :: Bytes }
|
||||
| Directory { entries :: Map FileName FileSystemObject }
|
||||
| SymLink { target :: Path }
|
||||
|
||||
Examples:
|
||||
|
||||
- a directory with contents
|
||||
|
||||
/nix/store/<hash>-hello-2.10
|
||||
├── bin
|
||||
│ └── hello
|
||||
└── share
|
||||
├── info
|
||||
│ └── hello.info
|
||||
└── man
|
||||
└── man1
|
||||
└── hello.1.gz
|
||||
|
||||
- a directory with relative symlink and other contents
|
||||
|
||||
/nix/store/<hash>-go-1.16.9
|
||||
├── bin -> share/go/bin
|
||||
├── nix-support/
|
||||
└── share/
|
||||
|
||||
- a directory with absolute symlink
|
||||
|
||||
/nix/store/d3k...-nodejs
|
||||
└── nix_node -> /nix/store/f20...-nodejs-10.24.
|
||||
|
||||
A bare file or symlink can be a root file system object.
|
||||
Examples:
|
||||
|
||||
/nix/store/<hash>-hello-2.10.tar.gz
|
||||
|
||||
/nix/store/4j5...-pkg-config-wrapper-0.29.2-doc -> /nix/store/i99...-pkg-config-0.29.2-doc
|
||||
|
||||
Symlinks pointing outside of their own root or to a store object without a matching reference are allowed, but might not function as intended.
|
||||
Examples:
|
||||
|
||||
- an arbitrarily symlinked file may change or not exist at all
|
||||
|
||||
/nix/store/<hash>-foo
|
||||
└── foo -> /home/foo
|
||||
|
||||
- if a symlink to a store path was not automatically created by Nix, it may be invalid or get invalidated when the store object is deleted
|
||||
|
||||
/nix/store/<hash>-bar
|
||||
└── bar -> /nix/store/abc...-foo
|
||||
|
||||
Nix file system objects do not support [hard links][hardlink]:
|
||||
each file system object which is not the root has exactly one parent and one name.
|
||||
However, as store objects are immutable, an underlying file system can use hard links for optimization.

# Store Path
|
||||
|
||||
Nix implements [references](store.md#reference) to [store objects](store.md#store-object) as *store paths*.
|
||||
|
||||
Store paths are pairs of
|
||||
|
||||
- a 20-byte [digest](#digest) for identification
|
||||
- a symbolic name for people to read.
|
||||
|
||||
Example:
|
||||
|
||||
- digest: `b6gvzjyb2pg0kjfwrjmg1vfhh54ad73z`
|
||||
- name: `firefox-33.1`
|
||||
|
||||
It is rendered to a file system path as the concatenation of
|
||||
|
||||
- [store directory](#store-directory)
|
||||
- path-separator (`/`)
|
||||
- [digest](#digest) rendered in a custom variant of [base-32](https://en.m.wikipedia.org/wiki/Base32) (20 arbitrary bytes become 32 ASCII characters)
|
||||
- hyphen (`-`)
|
||||
- name
|
||||
|
||||
Example:
|
||||
|
||||
/nix/store/b6gvzjyb2pg0kjfwrjmg1vfhh54ad73z-firefox-33.1
|
||||
|--------| |------------------------------| |----------|
|
||||
store directory digest name
|
||||
|
||||
## Store Directory
|
||||
|
||||
Every [store](./store.md) has a store directory.
|
||||
|
||||
If the store has a [file system representation](./store.md#files-and-processes), this directory contains the store’s [file system objects](#file-system-object), which can be addressed by [store paths](#store-path).
|
||||
|
||||
This means a store path is not just derived from the referenced store object itself, but depends on the store the store object is in.
|
||||
|
||||
> **Note**
|
||||
> The store directory defaults to `/nix/store`, but is in principle arbitrary.
|
||||
|
||||
It is important which store a given store object belongs to:
|
||||
Files in the store object can contain store paths, and processes may read these paths.
|
||||
Nix can only guarantee [referential integrity](store/closure.md) if store paths do not cross store boundaries.
|
||||
|
||||
Therefore one can only copy store objects to a different store if
|
||||
|
||||
- the source and target stores' directories match
|
||||
|
||||
or
|
||||
|
||||
- the store object in question has no references, that is, contains no store paths.
|
||||
|
||||
One cannot copy a store object to a store with a different store directory.
|
||||
Instead, it has to be rebuilt, together with all its dependencies.
|
||||
It is in general not enough to replace the store directory string in file contents, as this may render executables unusable by invalidating their internal offsets or checksums.
|
||||
|
||||
# Digest
|
||||
|
||||
In a [store path](#store-path), the [digest][digest] is the output of a [cryptographic hash function][hash] of either all *inputs* involved in building the referenced store object or its actual *contents*.
|
||||
|
||||
Store objects are therefore said to be either [input-addressed](#input-addressing) or [content-addressed](#content-addressing).
|
||||
|
||||
> **Historical Note**
|
||||
> The 20 byte restriction is because originally digests were [SHA-1][sha-1] hashes.
|
||||
> Nix now uses [SHA-256][sha-256], and longer hashes are still reduced to 20 bytes for compatibility.

||||

||||

|
||||
|
||||
### Reference scanning
|
||||
|
||||
When a new store object is built, Nix scans its file contents for store paths to construct its set of references.
|
||||
|
||||
The special format of a store path's [digest](#digest) allows reliably detecting it among arbitrary data.
|
||||
Nix uses the [closure](store.md#closure) of build inputs to derive the list of allowed store paths, to avoid false positives.
|
||||
|
||||
This way, scanning files captures run time dependencies without the user having to declare them explicitly.
|
||||
Doing it at build time and persisting references in the store object avoids repeating this time-consuming operation.
|
||||
|
||||
> **Note**
|
||||
> In practice, it is sometimes still necessary for users to declare certain dependencies explicitly, if they are to be preserved in the build result's closure.
|
||||
This depends on the specifics of the software to build and run.
|
||||
>
|
||||
> For example, Java programs are compressed after compilation, which obfuscates any store paths they may refer to and prevents Nix from automatically detecting them.
|
||||
|
||||
## Input Addressing
|
||||
|
||||
Input addressing means that the digest derives from how the store object was produced, namely its build inputs and build plan.
|
||||
|
||||
To compute the hash of a store object one needs a deterministic serialisation, i.e., a binary string representation which only changes if the store object changes.
|
||||
|
||||
Nix has a custom serialisation format called Nix Archive (NAR)
|
||||
|
||||
Store object references of this sort can *not* be validated from the content of the store object.
|
||||
Rather, a cryptographic signature has to be used to indicate that someone is vouching for the store object really being produced from a build plan with that digest.
|
||||
|
||||
## Content Addressing
|
||||
|
||||
Content addressing means that the digest derives from the store object's contents, namely its file system objects and references.
|
||||
If one knows content addressing was used, one can recalculate the reference and thus verify the store object.
|
||||
|
||||
Content addressing is currently only used for the special cases of source files and "fixed-output derivations", where the contents of a store object are known in advance.
|
||||
Content addressing of build results is still an [experimental feature subject to some restrictions](https://github.com/tweag/rfcs/blob/cas-rfc/rfcs/0062-content-addressed-paths.md).

# Store
|
||||
|
||||
A Nix store is a collection of *store objects* with references between them.
|
||||
It supports operations to manipulate that collection.
|
||||
|
||||
The following concept map is a graphical outline of this chapter.
|
||||
Arrows indicate suggested reading order.
|
||||
|
||||

|
||||
```
|
||||
|
||||
## Store Object
|
||||
|
||||
A store object can hold
|
||||
|
||||
- arbitrary *data*
|
||||
- *references* to other store objects.
|
||||
|
||||
Store objects can be build inputs, build results, or build tasks.
|
||||
|
||||
Store objects are [immutable][immutable-object]: once created, they do not change until they are deleted.
|
||||
|
||||
## Reference
|
||||
|
||||
A store object reference is an [opaque][opaque-data-type], [unique identifier][unique-identifier]:
|
||||
The only way to obtain references is by adding or building store objects.
|
||||
A reference will always point to exactly one store object.
|
||||
|
||||
## Operations
|
||||
|
||||
A Nix store can *add*, *retrieve*, and *delete* store objects.
|
||||
|
||||
[ data ]
|
||||
|
|
||||
V
|
||||
[ store ] ---> add ----> [ store' ]
|
||||
|
|
||||

|
||||
[ reference ]
|
||||
|
||||
<!-- -->
|
||||
|
||||
[ reference ]
|
||||
|
|
||||
V
|
||||
[ store ] ---> get
|
||||
|
|
||||
V
|
||||
[ store object ]
|
||||
|
||||
<!-- -->
|
||||
|
||||
[ reference ]
|
||||
|
|
||||
V
|
||||
[ store ] --> delete --> [ store' ]
|
||||
|
||||
|
||||
It can *perform builds*, that is, create new store objects by transforming build inputs into build outputs, using instructions from the build tasks.
|
||||
|
||||
|
||||
[ reference ]
|
||||
|
|
||||
V
|
||||
[ store ] --> build --(maybe)--> [ store' ]
|
||||
|
|
||||
V
|
||||
[ reference ]
|
||||
|
||||
|
||||
As it keeps track of references, it can [garbage-collect][garbage-collection] unused store objects.
|
||||
|
||||
|
||||
[ store ] --> collect garbage --> [ store' ]
|
||||
|
||||
## Files and Processes
|
||||
|
||||
Nix maps between its store model and the [Unix paradigm][unix-paradigm] of [files and processes][file-descriptor], by encoding immutable store objects and opaque identifiers as file system primitives: files and directories, and paths.
|
||||
That allows processes to resolve references contained in files and thus access the contents of store objects.
|
||||
|
||||
Store objects are therefore implemented as the pair of
|
||||
|
||||
- a [file system object](fso.md) for data
|
||||
- a set of [store paths](path.md) for references.
|
||||
|
||||
[unix-paradigm]: https://en.m.wikipedia.org/wiki/Everything_is_a_file
|
||||
[file-descriptor]: https://en.m.wikipedia.org/wiki/File_descriptor
|
||||
|
||||
The following diagram shows a radical simplification of how Nix interacts with the operating system:
|
||||
It uses files as build inputs, and build outputs are files again.
|
||||
On the operating system, files can be run as processes, which in turn operate on files.
|
||||
A build function also amounts to an operating system process (not depicted).

||||

||||

|

|

+-----------------------------------------------------------------+
|
||||
```
|
||||
|
||||
There exist different types of stores, which all follow this model.
|
||||
Examples:
|
||||
- store on the local file system
|
||||
- remote store accessible via SSH
|
||||
- binary cache store accessible via HTTP
|
||||
|
||||
To make store objects accessible to processes, stores ultimately have to expose store objects through the file system.

The Nix store's design is comparable to other build systems.

Usage of terms is, for historic reasons, not entirely consistent within the Nix ecosystem, and still subject to slow change.
|

||||
The following translation table points out similarities and equivalent terms, to help clarify their meaning and inform consistent use in the future.

# Closure
|
||||
|
||||
Nix stores ensure [referential integrity][referential-integrity]: for each store object in the store, all the store objects it references must also be in the store.
|
||||
|
||||
The set of all store objects reachable by following references from a given initial set of store objects is called a *closure*.
|
||||
|
||||
Adding, building, copying and deleting store objects must be done in a way that preserves referential integrity:
|
||||
|
||||
- A newly added store object cannot have references, unless it is a build task.
|
||||
|
||||
- Build results must only refer to store objects in the closure of the build inputs.
|
||||
|
||||
Building a store object will add appropriate references, according to the build task.
|
||||
|
||||
- Store objects being copied must refer to objects already in the destination store.
|
||||
|
||||
Recursive copying must either proceed in dependency order or be atomic.
|
||||
|
||||
- We can only safely delete store objects which are not reachable from any reference still in use.

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
|

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

|

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

[the manual for `nix-channel`](nix-channel.md)) can be abbreviated

## Testing
|
||||
|
||||
Nix comes with three different flavors of tests: unit, functional and integration.
|
||||
## Running tests
|
||||
|
||||
### Unit-tests
|
||||
|
||||
The unit-tests for each Nix library (`libexpr`, `libstore`, etc..) are defined
|
||||
under `src/{library_name}/tests` using the
|
||||
[googletest](https://google.github.io/googletest/) framework.
|
||||
[googletest](https://google.github.io/googletest/) and
|
||||
[rapidcheck](https://github.com/emil-e/rapidcheck) frameworks.
|
||||
|
||||
You can run the whole testsuite with `make check`, or the tests for a specific component with `make libfoo-tests_RUN`. Finer-grained filtering is also possible using the [--gtest_filter](https://google.github.io/googletest/advanced.html#running-a-subset-of-the-tests) command-line option.
|
||||
|
||||
### 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.

||||

||||

### Installer tests
|
||||
|

After a one-time setup, the Nix repository's GitHub Actions continuous integration (CI) workflow can test the installer each time you push to a branch.
|
||||
|
||||
Creating a Cachix cache for your installer tests and adding its authorization token to GitHub enables [two installer-specific jobs in the CI workflow](https://github.com/NixOS/nix/blob/88a45d6149c0e304f6eb2efcc2d7a4d0d569f8af/.github/workflows/ci.yml#L50-L91):

|
||||
- `armv7l-linux`
|
||||
- `x86_64-darwin`
|
||||
|
||||
- The `installer_test` job (which runs on `ubuntu-latest` and `macos-latest`) will try to install Nix with the cached installer and run a trivial Nix command.
|
||||

||||

1. Have a GitHub account with a fork of the [Nix repository](https://github.com/NixOS/nix).
|
||||
2. At cachix.org:
|
||||
- Create or log in to an account.
|
||||
- Create a Cachix cache using the format `<github-username>-nix-install-tests`.
|
||||
- Navigate to the new cache > Settings > Auth Tokens.
|
||||
- Generate a new Cachix auth token and copy the generated value.
|
||||
3. At github.com:
|
||||
- Navigate to your Nix fork > Settings > Secrets > Actions > New repository secret.
|
||||
- Name the secret `CACHIX_AUTH_TOKEN`.
|
||||
- Paste the copied value of the Cachix cache auth token.
|
||||
|
||||
#### Using the CI-generated installer for manual testing
|
||||
|
||||
After the CI run completes, you can check the output to extract the installer URL:
|
||||
1. Click into the detailed view of the CI run.
|
||||
2. Click into any `installer_test` run (the URL you're here to extract will be the same in all of them).
|
||||
3. Click into the `Run cachix/install-nix-action@v...` step and click the detail triangle next to the first log line (it will also be `Run cachix/install-nix-action@v...`)
|
||||
4. Copy the value of `install_url`
|
||||
5. To generate an install command, plug this `install_url` and your GitHub username into this template:
|
||||
|
||||
```console
|
||||
sh <(curl -L <install_url>) --tarball-url-prefix https://<github-username>-nix-install-tests.cachix.org/serve
|
||||
```
|
||||
|
||||
<!-- #### Manually generating test installers
|
||||
|
||||
There's obviously a manual way to do this, and it's still the only way for
|
||||
platforms that lack GA runners.
|
||||
|
||||
I did do this back in Fall 2020 (before the GA approach encouraged here). I'll
|
||||
sketch what I recall in case it encourages someone to fill in detail, but: I
|
||||
didn't know what I was doing at the time and had to fumble/ask around a lot--
|
||||
so I don't want to uphold any of it as "right". It may have been dumb or
|
||||
the _hard_ way from the getgo. Fundamentals may have changed since.
|
||||
|
||||
Here's the build command I used to do this on and for x86_64-darwin:
|
||||
nix build --out-link /tmp/foo ".#checks.x86_64-darwin.binaryTarball"
|
||||
|
||||
I used the stable out-link to make it easier to script the next steps:
|
||||
link=$(readlink /tmp/foo)
|
||||
cp $link/*-darwin.tar.xz ~/somewheres
|
||||
|
||||
I've lost the last steps and am just going from memory:
|
||||
|
||||
From here, I think I had to extract and modify the `install` script to point
|
||||
it at this tarball (which I scped to my own site, but it might make more sense
|
||||
to just share them locally). I extracted this script once and then just
|
||||
search/replaced in it for each new build.
|
||||
|
||||
The installer now supports a `--tarball-url-prefix` flag which _may_ have
|
||||
solved this need?
|
||||
-->
|
||||
|
||||
### Checking links in the manual
|
||||
|
||||
The build checks for broken internal links.
|
||||
This happens late in the process, so `nix build` is not suitable for iterating.
|
||||
To build the manual incrementally, run:
|
||||
|
||||
```console
|
||||
make html -j $NIX_BUILD_CORES
|
||||
```
|
||||
|
||||
In order to reflect changes to the [Makefile], clear all generated files before re-building:
|
||||
|
||||
[Makefile]: https://github.com/NixOS/nix/blob/master/doc/manual/local.mk
|
||||
|
||||
```console
|
||||
rm $(git ls-files doc/manual/ -o | grep -F '.md') && rmdir doc/manual/src/command-ref/new-cli && make html -j $NIX_BUILD_CORES
|
||||
```
|
||||
|
||||
[`mdbook-linkcheck`] does not implement checking [URI fragments] yet.
|
||||
|
||||
[`mdbook-linkcheck`]: https://github.com/Michael-F-Bryan/mdbook-linkcheck
|
||||
[URI fragments]: https://en.m.wikipedia.org/wiki/URI_fragment
|
||||
|
||||
#### `@docroot@` variable
|
||||
|
||||
`@docroot@` provides a base path for links that occur in reusable snippets or other documentation that doesn't have a base path of its own.
|
||||
|
||||
If a broken link occurs in a snippet that was inserted into multiple generated files in different directories, use `@docroot@` to reference the `doc/manual/src` directory.
|
||||
|
||||
If the `@docroot@` literal appears in an error message from the `mdbook-linkcheck` tool, the `@docroot@` replacement needs to be applied to the generated source file that mentions it.
|
||||
See existing `@docroot@` logic in the [Makefile].
|
||||
Regular markdown files used for the manual have a base path of their own and they can use relative paths instead of `@docroot@`.

||||
A description of a build task. The result of a derivation is a
|
||||
store object. Derivations are typically specified in Nix expressions
|
||||
using the [`derivation` primitive](language/derivations.md). These are
|
||||
using the [`derivation` primitive](./language/derivations.md). These are
|
||||
translated into low-level *store derivations* (implicitly by
|

`nix-env` and `nix-build`, or explicitly by `nix-instantiate`).
|
||||
|
||||
[derivation]: #gloss-derivation
|
||||
|
||||
- [store derivation]{#gloss-store-derivation}\
|
||||
A [derivation] represented as a `.drv` file in the [store].
|
||||
It has a [store path], like any [store object].
|
||||
|
||||
Example: `/nix/store/g946hcz4c8mdvq2g8vxx42z51qb71rvp-git-2.38.1.drv`
|
||||
|
||||
See [`nix show-derivation`](./command-ref/new-cli/nix3-show-derivation.md) (experimental) for displaying the contents of store derivations.

||||
- [realise]{#gloss-realise}, realisation\
|
||||
Ensure a [store path] is [valid][validity].
|
||||
|
||||
This means either running the `builder` executable as specified in the corresponding [derivation] or fetching a pre-built [store object] from a [substituter].
|
||||
|
||||
See [`nix-build`](./command-ref/nix-build.md) and [`nix-store --realise`](./command-ref/nix-store.md#operation---realise).

|
||||
|
||||
[realise]: #gloss-realise
|
||||
|
||||
- [content-addressed derivation]{#gloss-content-addressed-derivation}\
|
||||
A derivation which has the
|
||||
[`__contentAddressed`](./language/advanced-attributes.md#adv-attr-__contentAddressed)
|
||||
attribute set to `true`.
|
||||
|
||||
- [fixed-output derivation]{#gloss-fixed-output-derivation}\
|
||||
A derivation which includes the
|
||||
[`outputHash`](./language/advanced-attributes.md#adv-attr-outputHash) attribute.
|
||||
|
||||
- [store]{#gloss-store}\
|
||||
The location in the file system where store objects live. Typically
|
||||
`/nix/store`.
|
||||
|
||||
From the perspective of the location where Nix is
|
||||
invoked, the Nix store can be referred to
|
||||
as a "_local_" or a "_remote_" one:
|
||||
|
||||
+ A *local store* exists on the filesystem of
|
||||
the machine where Nix is invoked. You can use other
|
||||
local stores by passing the `--store` flag to the
|
||||
`nix` command. Local stores can be used for building derivations.
|
||||
|
||||
+ A *remote store* exists anywhere other than the
|
||||
local filesystem. One example is the `/nix/store`
|
||||
directory on another machine, accessed via `ssh` or
|
||||
served by the `nix-serve` Perl script.
|
||||
|
||||
[store]: #gloss-store
|
||||
|
||||
- [chroot store]{#gloss-chroot-store}\
|
||||
A local store whose canonical path is anything other than `/nix/store`.
|
||||
|
||||
- [binary cache]{#gloss-binary-cache}\
|
||||
A *binary cache* is a Nix store which uses a different format: its
|
||||
metadata and signatures are kept in `.narinfo` files rather than in a
|
||||
Nix database. This different format simplifies serving store objects
|
||||
over the network, but cannot host builds. Examples of binary caches
|
||||
include S3 buckets and the [NixOS binary
|
||||
cache](https://cache.nixos.org).
|
||||
|
||||
- [store path]{#gloss-store-path}\
|
||||
The location in the file system of a store object, i.e., an

||||
The location of a [store object] in the file system, i.e., an
|
||||
immediate child of the Nix store directory.
|
||||
|
||||
Example: `/nix/store/a040m110amc4h71lds2jmr8qrkj2jhxd-git-2.38.1`
|
||||
|
||||
[store path]: #gloss-store-path
|
||||
|
||||
- [store object]{#gloss-store-object}\
|
||||
A file that is an immediate child of the Nix store directory. These
|
||||
can be regular files, but also entire directory trees. Store objects
|
||||
can be sources (objects copied from outside of the store),
|
||||
derivation outputs (objects produced by running a build action), or
|
||||
derivations (files describing a build action).

[string]: ./values.md#type-string
|
||||
[path]: ./values.md#type-path
|
||||
[number]: ./values.md#type-number
|
||||
[list]: ./values.md#list
|
||||
[attribute set]: ./values.md#attribute-set
|
||||
|
||||
## Attribute selection
|
||||
|
||||
Select the attribute denoted by attribute path *attrpath* from [attribute set] *attrset*.
|
||||
If the attribute doesn’t exist, return *value* if provided, otherwise abort evaluation.
|
||||
|
||||
<!-- FIXME: the following should to into its own language syntax section, but that needs more work to fit in well -->
|
||||
|
||||
An attribute path is a dot-separated list of attribute names.
|
||||
An attribute name can be an identifier or a string.
|
||||
|
||||
> *attrpath* = *name* [ `.` *name* ]...
|
||||
> *name* = *identifier* | *string*
|
||||
> *identifier* ~ `[a-zA-Z_][a-zA-Z0-9_'-]*`
|
||||
|
||||
[Attribute selection]: #attribute-selection
|
||||
|
||||
## Has attribute
|
||||
|
||||
> *attrset* `?` *attrpath*
|
||||
|
||||
Test whether [attribute set] *attrset* contains the attribute denoted by *attrpath*.
|
||||
The result is a [Boolean] value.
|
||||
|
||||
[Boolean]: ./values.md#type-boolean
|
||||
|
||||
[Has attribute]: #has-attribute
|
||||
|
||||
## Arithmetic
|
||||
|
||||
Numbers are type-compatible:
|
||||
Pure integer operations will always return integers, whereas any operation involving at least one floating point number return a floating point number.
|
||||
|
||||
See also [Comparison] and [Equality].
|
||||
|
||||
The `+` operator is overloaded to also work on strings and paths.
|
||||
|
||||
[arithmetic]: #arithmetic
|
||||
|
||||
## String concatenation
|
||||
|
||||
> *string* `+` *string*
|
||||
|
||||
Concatenate two [string]s and merge their string contexts.
|
||||
|
||||
[String concatenation]: #string-concatenation
|
||||
|
||||
## Path concatenation
|
||||
|
||||
> *path* `+` *path*
|
||||
|
||||
Concatenate two [path]s.
|
||||
The result is a path.
|
||||
|
||||
[Path concatenation]: #path-concatenation
|
||||
|
||||
## Path and string concatenation
|
||||
|
||||
> *path* + *string*
|
||||
|
||||
Concatenate *[path]* with *[string]*.
|
||||
The result is a path.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> The string must not have a string context that refers to a [store path].
|
||||
|
||||
[Path and string concatenation]: #path-and-string-concatenation
|
||||
|
||||
## String and path concatenation
|
||||
|
||||
> *string* + *path*
|
||||
|
||||
Concatenate *[string]* with *[path]*.
|
||||
The result is a string.
|
||||
|
||||
> **Important**
|
||||
>
|
||||
> The file or directory at *path* must exist and is copied to the [store].
|
||||
> The path appears in the result as the corresponding [store path].
|
||||
|
||||
[store path]: ../glossary.md#gloss-store-path
|
||||
[store]: ../glossary.md#gloss-store
|
||||
|
||||
[Path and string concatenation]: #path-and-string-concatenation
|
||||
|
||||
## Update
|
||||
|
||||
> *attrset1* // *attrset2*
|
||||
|
||||
Update [attribute set] *attrset1* with names and values from *attrset2*.
|
||||
|
||||
The returned attribute set will have of all the attributes in *attrset1* and *attrset2*.
|
||||
If an attribute name is present in both, the attribute value from the latter is taken.
|
||||
|
||||
[Update]: #update
|
||||
|
||||
## Comparison
|
||||
|
||||
Comparison is
|
||||
|
||||
- [arithmetic] for [number]s
|
||||
- lexicographic for [string]s and [path]s
|
||||
- item-wise lexicographic for [list]s:
|
||||
elements at the same index in both lists are compared according to their type and skipped if they are equal.
|
||||
|
||||
All comparison operators are implemented in terms of `<`, and the following equivalencies hold:
|
||||
|
||||
| comparison | implementation |
|
||||
|--------------|-----------------------|
|
||||
| *a* `<=` *b* | `! (` *b* `<` *a* `)` |
|
||||
| *a* `>` *b* | *b* `<` *a* |
|
||||
| *a* `>=` *b* | `! (` *a* `<` *b* `)` |
|
||||
|
||||
[Comparison]: #comparison-operators
|
||||
|
||||
## Equality
|
||||
|
||||
- [Attribute sets][attribute set] and [list]s are compared recursively, and therefore are fully evaluated.
|
||||
- Comparison of [function]s always returns `false`.
|
||||
- Numbers are type-compatible, see [arithmetic] operators.
|
||||
- Floating point numbers only differ up to a limited precision.
|
||||
|
||||
[function]: ./constructs.md#functions
|
||||
|
||||
[Equality]: #equality
|
||||
|
||||
## Logical implication
|
||||
|
||||
Equivalent to `!`*b1* `||` *b2*.
|
||||
|
||||
[Logical implication]: #logical-implication

# 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"; }

|
||||
|
||||
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].

`./${foo}-${bar}.nix` is a more convenient way of writing

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].

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].

# 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.

||||

|
||||
# 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.
|
||||
|
||||
* Allow explicitly selecting outputs in a store derivation installable, just like we can do with other sorts of installables.
|
||||
For example,
|
||||
```shell-session
|
||||
# nix build /nix/store/gzaflydcr6sb3567hap9q6srzx8ggdgg-glibc-2.33-78.drv^dev
|
||||
```
|
||||
now works just as
|
||||
```shell-session
|
||||
# nix build nixpkgs#glibc^dev
|
||||
```
|
||||
does already.
|
||||
|
||||
* On Linux, `nix develop` now sets the
|
||||
[*personality*](https://man7.org/linux/man-pages/man2/personality.2.html)
|
||||
for the development shell in the same way as the actual build of the
|
||||
derivation. This makes shells for `i686-linux` derivations work
|
||||
correctly on `x86_64-linux`.
|
||||
|
||||
* You can now disable the global flake registry by setting the `flake-registry`
|
||||
configuration option to an empty string. The same can be achieved at runtime with
|
||||
`--flake-registry ""`.

* The `builtins.readDir` function has been optimized when encountering not-yet-known

file types from POSIX's `readdir`. In such cases the type of each file is/was

discovered by making multiple syscalls. This change makes these operations
|
||||
lazy such that these lookups will only be performed if the attribute is used.
|

This optimization affects a minority of filesystems and operating systems.

# 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
|
||||
|
||||
During the discussion meeting, the team triages new items.
|
||||
To be considered, issues and pull requests must have a high-level description to provide the whole team with the necessary context at a glance.
|
||||
|
||||
On every meeting, at least one item from each of the following categories is inspected:
|
||||
|
||||
1. [critical](https://github.com/NixOS/nix/labels/critical)
|
||||
2. [security](https://github.com/NixOS/nix/labels/security)
|
||||
3. [regression](https://github.com/NixOS/nix/labels/regression)
|
||||
4. [bug](https://github.com/NixOS/nix/issues?q=is%3Aopen+label%3Abug+sort%3Areactions-%2B1-desc)
|
||||
|
||||
- [oldest pull requests](https://github.com/NixOS/nix/pulls?q=is%3Apr+is%3Aopen+sort%3Acreated-asc)
|
||||
- [most popular pull requests](https://github.com/NixOS/nix/pulls?q=is%3Apr+is%3Aopen+sort%3Areactions-%2B1-desc)
|
||||
- [oldest issues](https://github.com/NixOS/nix/issues?q=is%3Aissue+is%3Aopen+sort%3Acreated-asc)
|
||||
- [most popular issues](https://github.com/NixOS/nix/issues?q=is%3Aissue+is%3Aopen+sort%3Areactions-%2B1-desc)
|
||||
|
||||
Team members can also add pull requests or issues they would like the whole team to consider.
|
||||
|
||||
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 deemed 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.
|
||||
|
||||
As a general guideline, the order of items is determined as follows:
|
||||
|
||||
- Prioritise pull requests over issues
|
||||
|
||||
Contributors who took the time to implement concrete change proposals should not wait indefinitely.
|
||||
|
||||
- Prioritise fixing bugs over documentation, improvements or new features
|
||||
|
||||
The team values stability and accessibility higher than raw functionality.
|
||||
|
||||
- Interleave issues and PRs
|
||||
|
||||
This way issues without attempts at a solution get a chance to get addressed.
|
||||
|
||||
- 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:

||||

.description = R"(
|
||||
Add *path* to the Nix search path. The Nix search path is
|
||||
initialized from the colon-separated [`NIX_PATH`](@docroot@/command-ref/env-common.md#env-NIX_PATH) environment
|
||||
variable, and is used to look up the location of Nix expressions using [paths](@docroot@/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
|
||||
```
|
||||
|
||||
makes `<nixpkgs>` refer to a particular branch of the
|
||||
`NixOS/nixpkgs` repository on GitHub.
