## Store Object
|
||||
|
||||
A Nix store is a collection of *store objects* with *references* between them.
|
||||
A store object consists of
|
||||
|
||||
- A [file system object](./file-system-object.md) as data
|
||||
- A set of [store paths](./store-path.md) as references to other store objects
|
||||
|
||||
Store objects are [immutable](https://en.wikipedia.org/wiki/Immutable_object):
|
||||
Once created, they do not change until they are deleted.

# Store Path
|
||||
|
||||
Nix implements references to [store objects](./index.md#store-object) as *store paths*.
|
||||
|
||||
Think of a store path as an [opaque], [unique identifier]:
|
||||
The only way to obtain store path is by adding or building store objects.
|
||||
A store path will always reference exactly one store object.
|
||||
|
||||
[opaque]: https://en.m.wikipedia.org/wiki/Opaque_data_type
|
||||
[unique identifier]: https://en.m.wikipedia.org/wiki/Unique_identifier
|
||||
|
||||
Store paths are pairs of
|
||||
|
||||
- A 20-byte digest for identification
|
||||
- A symbolic name for people to read
|
||||
|
||||
> **Example**
|
||||
>
|
||||
> - Digest: `b6gvzjyb2pg0kjfwrjmg1vfhh54ad73z`
|
||||
> - Name: `firefox-33.1`
|
||||
|
||||
To make store objects accessible to operating system processes, stores have to expose store objects through the file system.
|
||||
|
||||
A store path is rendered to a file system path as the concatenation of
|
||||
|
||||
- [Store directory](#store-directory) (typically `/nix/store`)
|
||||
- Path separator (`/`)
|
||||
- Digest rendered in a custom variant of [Base32](https://en.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 [Nix store](./index.md) has a store directory.
|
||||
|
||||
Not every store can be accessed through the file system.
|
||||
But if the store has a file system representation, the store directory contains the store’s [file system objects], which can be addressed by [store paths](#store-path).
|
||||
|
||||
[file system objects]: ./file-system-object.md
|
||||
|
||||
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 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.

# Description
|
||||
|
||||
This command updates the lock file of a flake (`flake.lock`) so that
|
||||
it contains a lock for every flake input specified in
|
||||
`flake.nix`. Existing lock file entries are not updated unless
|
||||
required by a flag such as `--update-input`.
|
||||
This command adds inputs to the lock file of a flake (`flake.lock`)
|
||||
so that it contains a lock for every flake input specified in
|
||||
`flake.nix`. Existing lock file entries are not updated.
|
||||
|
||||
Note that every command that operates on a flake will also update the
|
||||
lock file if needed, and supports the same flags. Therefore,
|
||||
|
||||
```console
|
||||
# nix flake lock --update-input nixpkgs
|
||||
# nix build
|
||||
```
|
||||
|
||||
is equivalent to:
|
||||
|
||||
```console
|
||||
# nix build --update-input nixpkgs
|
||||
```
|
||||
|
||||
Thus, this command is only useful if you want to update the lock file
|
||||
separately from any other action such as building.
|
||||
If you want to update existing lock entries, use
|
||||
[`nix flake update`](@docroot@/command-ref/new-cli/nix3-flake-update.md)

# Description
|
||||
|
||||
This command recreates the lock file of a flake (`flake.lock`), thus
|
||||
updating the lock for every unlocked input (like `nixpkgs`) to its
|
||||
current version. This is equivalent to passing `--recreate-lock-file`
|
||||
to any command that operates on a flake. That is,
|
||||
This command updates the inputs in a lock file (`flake.lock`).
|
||||
**By default, all inputs are updated**. If the lock file doesn't exist
|
||||
yet, it will be created. If inputs are not in the lock file yet, they will be added.
|
||||
|
||||
```console
|
||||
# nix flake update
|
||||
# nix build

```
|
||||
Unlike other `nix flake` commands, `nix flake update` takes a list of names of inputs
|
||||
to update as its positional arguments and operates on the flake in the current directory.
|
||||
You can pass a different flake-url with `--flake` to override that default.
|
||||
|
||||
is equivalent to:
|
||||
|
||||
```console
|
||||
# nix build --recreate-lock-file
|
||||
```
|
||||
The related command [`nix flake lock`](@docroot@/command-ref/new-cli/nix3-flake-lock.md)
|
||||
also creates lock files and adds missing inputs, but is safer as it
|
||||
will never update inputs already in the lock file.
