# 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].
|
||||
|
||||
```
|
||||
+-----------------------------------------------------------------+
|
||||
| Nix |
|
||||
| [ commmand line interface ]------, |
|
||||
| | | |
|
||||
| evaluates | |
|
||||
| | manages |
|
||||
| V | |
|
||||
| [ configuration language ] | |
|
||||
| | | |
|
||||
| +-----------------------------|-------------------V-----------+ |
|
||||
| | store evaluates to | |
|
||||
| | | | |
|
||||
| | referenced by V builds | |
|
||||
| | [ build input ] ---> [ build plan ] ---> [ build result ] | |
|
||||
| | | |
|
||||
| +-------------------------------------------------------------+ |
|
||||
+-----------------------------------------------------------------+
|
||||
```
|
||||
|
||||
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.
|
||||
|
||||
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 command line and Nix language are what users interact 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.
|
||||
|
||||
A build plan is a series of *build tasks*.
|
||||
Each build task has a special build input which is used as *build instructions*.
|
||||
The result of a build task can be input to another build task.
|
||||
|
||||

# 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:
|
||||
|

|
||||
|
||||
## 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' ]

||||

||||

||||
|
||||

|
||||
|
||||

|
||||
|
|
||||
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.

# A [Rosetta stone][rosetta-stone] for build system terminology
|

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.

|

### 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):
|
||||
|
||||
- The `installer` job generates installers for the platforms below and uploads them to your Cachix cache:
|
||||
- `x86_64-linux`
|
||||
- `armv6l-linux`
|
||||
- `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.
|
||||
|
||||
#### One-time setup
|
||||
|
||||
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?

the machine where Nix is invoked. You can use other

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

cache](https://cache.nixos.org).
