The list of remote machines can be specified on the command line or in
the Nix configuration file. The former is convenient for testing. For
example, the following command allows you to build a derivation for
`x86_64-darwin` on a Linux machine:
The [list of remote build machines](@docroot@/command-ref/conf-file.md#conf-builders) can be specified on the command line or in the Nix configuration file.
For example, the following command allows you to build a derivation for `x86_64-darwin` on a Linux machine:
```console
$ uname
@ -60,97 +52,20 @@ $ cat ./result
Darwin
```
It is possible to specify multiple builders separated by a semicolon or
a newline, e.g.
It is possible to specify multiple build machines separated by a semicolon or a newline, e.g.
```console
--builders 'ssh://mac x86_64-darwin ; ssh://beastie x86_64-freebsd'
```
Each machine specification consists of the following elements, separated
by spaces. Only the first element is required. To leave a field at its
default, set it to `-`.
1. The URI of the remote store in the format
`ssh://[username@]hostname`, e.g. `ssh://nix@mac` or `ssh://mac`.
For backward compatibility, `ssh://` may be omitted. The hostname
may be an alias defined in your `~/.ssh/config`.
2. A comma-separated list of Nix platform type identifiers, such as
`x86_64-darwin`. It is possible for a machine to support multiple
platform types, e.g., `i686-linux,x86_64-linux`. If omitted, this
defaults to the local platform type.
3. The SSH identity file to be used to log in to the remote machine. If
omitted, SSH will use its regular identities.
4. The maximum number of builds that Nix will execute in parallel on
the machine. Typically this should be equal to the number of CPU
cores. For instance, the machine `itchy` in the example will execute
up to 8 builds in parallel.
5. The “speed factor”, indicating the relative speed of the machine. If
there are multiple machines of the right type, Nix will prefer the
fastest, taking load into account.
6. A comma-separated list of *supported features*. If a derivation has
the `requiredSystemFeatures` attribute, then Nix will only perform
the derivation on a machine that has the specified features. For
instance, the attribute
```nix
requiredSystemFeatures = [ "kvm" ];
```
will cause the build to be performed on a machine that has the `kvm`
feature.
7. A comma-separated list of *mandatory features*. A machine will only
be used to build a derivation if all of the machine’s mandatory
features appear in the derivation’s `requiredSystemFeatures`
attribute.
8. The (base64-encoded) public host key of the remote machine. If omitted, SSH
will use its regular known-hosts file. Specifically, the field is calculated
via `base64 -w0 /etc/ssh/ssh_host_ed25519_key.pub`.
For example, the machine specification
nix@scratchy.labs.cs.uu.nl i686-linux /home/nix/.ssh/id_scratchy_auto 8 1 kvm
nix@itchy.labs.cs.uu.nl i686-linux /home/nix/.ssh/id_scratchy_auto 8 2
nix@poochie.labs.cs.uu.nl i686-linux /home/nix/.ssh/id_scratchy_auto 1 2 kvm benchmark
specifies several machines that can perform `i686-linux` builds.
However, `poochie` will only do builds that have the attribute
```nix
requiredSystemFeatures = [ "benchmark" ];
```
or
```nix
requiredSystemFeatures = [ "benchmark" "kvm" ];
```
`itchy` cannot do builds that require `kvm`, but `scratchy` does support
such builds. For regular builds, `itchy` will be preferred over
`scratchy` because it has a higher speed factor.
Remote builders can also be configured in `nix.conf`, e.g.
Remote build machines can also be configured in [`nix.conf`](@docroot@/command-ref/conf-file.md), e.g.
builders = ssh://mac x86_64-darwin ; ssh://beastie x86_64-freebsd
Finally, remote builders can be configured in a separate configuration
file included in `builders` via the syntax `@file`. For example,
Finally, remote build machines can be configured in a separate configuration
file included in `builders` via the syntax `@/path/to/file`. For example,
builders = @/etc/nix/machines
causes the list of machines in `/etc/nix/machines` to be included. (This
is the default.)
If you want the builders to use caches, you likely want to set the
option `builders-use-substitutes` in your local `nix.conf`.
To build only on remote builders and disable building on the local
machine, you can use the option `--max-jobs 0`.

### Build process
Releases have a precomputed `rl-MAJOR.MINOR.md`, and no `rl-next.md`.
Set `buildUnreleasedNotes = true;` in `flake.nix` to build the release notes on the fly.
## Branches
- [`master`](https://github.com/NixOS/nix/commits/master)
The main development branch. All changes are approved and merged here.
When developing a change, create a branch based on the latest `master`.
Maintainers try to [keep it in a release-worthy state](#reverting).
- [`maintenance-*.*`](https://github.com/NixOS/nix/branches/all?query=maintenance)
These branches are the subject of backports only, and are
also [kept](#reverting) in a release-worthy state.
See [`maintainers/backporting.md`](https://github.com/NixOS/nix/blob/master/maintainers/backporting.md)

See [`maintainers/backporting.md`](https://github.com/NixOS/nix/blob/master/maintainers/backporting.md)
- [_other_](https://github.com/NixOS/nix/branches/all)
Branches that do not conform to the above patterns should be feature branches.
## Reverting
If a change turns out to be merged by mistake, or contain a regression, it may be reverted.
A revert is not a rejection of the contribution, but merely part of an effective development process.
It makes sure that development keeps running smoothly, with minimal uncertainty, and less overhead.
If maintainers have to worry too much about avoiding reverts, they would not be able to merge as much.
By embracing reverts as a good part of the development process, everyone wins.
However, taking a step back may be frustrating, so maintainers will be extra supportive on the next try.

To install the latest version Nix, run the following command:
```console
$ curl -L https://nixos.org/nix/install | sh

This will run the installer interactively (causing it to explain what
it is doing more explicitly), and perform the default "type" of install
for your platform:
- single-user on Linux
- multi-user on macOS
This performs the default type of installation for your platform:

To check what it does and how it can be customised further, [download and edit the second-stage installation script](#installing-from-a-binary-tarball).
# Installing a pinned Nix version from a URL
Version-specific installation URLs for all Nix versions since 1.11.16 can be found at [releases.nixos.org](https://releases.nixos.org/?prefix=nix/).
The directory for each version contains the corresponding SHA-256 hash.
All installation scripts are invoked the same way:
```console
$ export VERSION=2.19.2
$ curl -L https://releases.nixos.org/nix/nix-$VERSION/install | sh
```
# Multi User Installation
The multi-user Nix installation creates system users and a system service for the Nix daemon.
Supported systems:
- Linux running systemd, with SELinux disabled
- macOS
To explicitly instruct the installer to perform a multi-user installation on your system:
```console

The install script will modify the first writable file from amongst
`.bash_profile`, `.bash_login` and `.profile` to source
`~/.nix-profile/etc/profile.d/nix.sh`. You can set the
`NIX_INSTALLER_NO_MODIFY_PROFILE` environment variable before executing
the install script to disable this behaviour.

The multi-user installation of Nix will create build users between the
user IDs 30001 and 30032, and a group with the group ID 30000. You
can run this under your usual user account or root. The script
will invoke `sudo` as needed.
> **Note**

> $ tar xfj nix-$VERSION-$SYSTEM.tar.xz
> $ cd nix-$VERSION-$SYSTEM
> $ ./install
> $ popd
> ```
The installer will modify `/etc/bashrc`, and `/etc/zshrc` if they exist.
The installer will first back up these files with a `.backup-before-nix`
extension. The installer will also create `/etc/profile.d/nix.sh`.
The installer can be customised with the environment variables declared in the file named `install-multi-user`.

# Derivation JSON Format
> **Warning**
>
> This JSON format is currently

> and subject to change.
The JSON serialization of a
[derivations](@docroot@/glossary.md#gloss-store-derivation)
is a JSON object with the following fields:
* `name`:
The name of the derivation.
This is used when calculating the store paths of the derivation's outputs.
* `outputs`:
Information about the output paths of the derivation.
This is a JSON object with one member per output, where the key is the output name and the value is a JSON object with these fields:
* `path`: The output path.
* `hashAlgo`:
For fixed-output derivations, the hashing algorithm (e.g. `sha256`), optionally prefixed by `r:` if `hash` denotes a NAR hash rather than a flat file hash.
* `hash`:
For fixed-output derivations, the expected content hash in base-16.
> **Example**
>
> ```json
> "outputs": {
> "out": {
> "path": "/nix/store/2543j7c6jn75blc3drf4g5vhb1rhdq29-source",

> }
> }
> ```
* `inputSrcs`:
A list of store paths on which this derivation depends.
* `inputDrvs`:
A JSON object specifying the derivations on which this derivation depends, and what outputs of those derivations.
> **Example**
>
> ```json
> "inputDrvs": {
> "/nix/store/6lkh5yi7nlb7l6dr8fljlli5zfd9hq58-curl-7.73.0.drv": ["dev"],
> "/nix/store/fn3kgnfzl5dzym26j8g907gq3kbm8bfh-unzip-6.0.drv": ["out"]
> }
> ```
specifies that this derivation depends on the `dev` output of `curl`, and the `out` output of `unzip`.
* `system`:
The system type on which this derivation is to be built
(e.g. `x86_64-linux`).
* `builder`:
The absolute path of the program to be executed to run the build.
Typically this is the `bash` shell
(e.g. `/nix/store/r3j288vpmczbl500w6zz89gyfa4nr0b1-bash-4.4-p23/bin/bash`).
* `args`:
The command-line arguments passed to the `builder`.
* `env`:
The environment passed to the `builder`.

### `.narinfo` extra fields
This meta data is specific to the "binary cache" family of Nix store types.
This information is not intrinsic to the store object, but about how it is stored.
* `url`:
Where to download a compressed archive of the file system objects of this store object.
* `compression`:
The compression format that the archive is in.
* `fileHash`:
A digest for the compressed archive itself, as opposed to the data contained within.

The size of the compressed archive itself.
## Computed closure fields
These fields are not stored at all, but computed by traverising the other other fields across all the store objects in a [closure].
* `closureSize`:
The total size of the compressed archive itself for this object, and the compressed archive of every object in this object's [closure].
### `.narinfo` extra fields
* `closureSize`:
The total size of this store object and every other object in its [closure].

# Complete Store Path Calculation
This is the complete specification for how store paths are calculated.
The format of this specification is close to [Extended Backus–Naur form](https://en.wikipedia.org/wiki/Extended_Backus%E2%80%93Naur_form), but must deviate for a few things such as hash functions which we treat as bidirectional for specification purposes.
Regular users do *not* need to know this information --- store paths can be treated as black boxes computed from the properties of the store objects they refer to.
But for those interested in exactly how Nix works, e.g. if they are reimplementing it, this information can be useful.
## Store path proper
```ebnf
store-path = store-dir "/" digest "-" name
```
where
- `name` = the name of the store object.
- `store-dir` = the [store directory](@docroot@/store/store-path.md#store-directory)
- `digest` = base-32 representation of the first 160 bits of a [SHA-256] hash of `fingerprint`
This the hash part of the store name
## Fingerprint
- ```ebnf
fingerprint = type ":" sha256 ":" inner-digest ":" store ":" name
```
Note that it includes the location of the store as well as the name to make sure that changes to either of those are reflected in the hash
(e.g. you won't get `/nix/store/<digest>-name1` and `/nix/store/<digest>-name2`, or `/gnu/store/<digest>-name1`, with equal hash parts).
- `type` = one of:
- ```ebnf
| "text" ( ":" store-path )*
```
for encoded derivations written to the store.
The optional trailing store paths are the references of the store object.
- ```ebnf
| "source" ( ":" store-path )*
```
For paths copied to the store and hashed via a [Nix Archive (NAR)] and [SHA-256][sha-256].
Just like in the text case, we can have the store objects referenced by their paths.
Additionally, we can have an optional `:self` label to denote self reference.
- ```ebnf
| "output:" id
```
For either the outputs built from derivations,
paths copied to the store hashed that area single file hashed directly, or the via a hash algorithm other than [SHA-256][sha-256].
(in that case "source" is used; this is only necessary for compatibility).
`id` is the name of the output (usually, "out").
For content-addressed store objects, `id`, is always "out".
- `inner-digest` = base-16 representation of a SHA-256 hash of `inner-fingerprint`
## Inner fingerprint
- `inner-fingerprint` = one of the following based on `type`:
- if `type` = `"text:" ...`:
the string written to the resulting store path.
- if `type` = `"source:" ...`:
the the hash of the [Nix Archive (NAR)] serialization of the [file system object](@docroot@/store/file-system-object.md) of the store object.
- if `type` = `"output:" id`:
- For input-addressed derivation outputs:
the [ATerm](@docroot@/protocols/derivation-aterm.md) serialization of the derivation modulo fixed output derivations.
- For content-addressed store paths:
```ebnf
"fixed:out:" rec algo ":" hash ":"
```
where
- `rec` = one of:
- ```ebnf
| ""
```
(empty string) for hashes of the flat (single file) serialization
- ```ebnf
| "r:"
```
hashes of the for [Nix Archive (NAR)] (arbitrary file system object) serialization
- ```ebnf
| "git:"
```
hashes of the [Git blob/tree](https://git-scm.com/book/en/v2/Git-Internals-Git-Objects) [Merkel tree](https://en.wikipedia.org/wiki/Merkle_tree) format
- ```ebnf
algo = "md5" | "sha1" | "sha256"
```
- `hash` = base-16 representation of the path or flat hash of the contents of the path (or expected contents of the path for fixed-output derivations).
Note that `id` = `"out"`, regardless of the name part of the store path.
Also note that NAR + SHA-256 must not use this case, and instead must use the `type` = `"source:" ...` case.
[Nix Archive (NAR)]: @docroot@/glossary.md#gloss-NAR
[sha-256]: https://en.m.wikipedia.org/wiki/SHA-256
### Historical Note
The `type` = `"source:" ...` and `type` = `"output:out"` grammars technically overlap in purpose,
in that both can represent data hashed by its SHA-256 NAR serialization.
The original reason for this way of computing names was to prevent name collisions (for security).
For instance, the thinking was that it shouldn't be feasible to come up with a derivation whose output path collides with the path for a copied source.
The former would have an `inner-fingerprint` starting with `output:out:`, while the latter would have an `inner-fingerprint` starting with `source:`.
Since `64519cfd657d024ae6e2bb74cb21ad21b886fd2a` (2008), however, it was decided that separating derivation-produced vs manually-hashed content-addressed data like this was not useful.
Now, data that is content-addressed with SHA-256 + NAR-serialization always uses the `source:...` construction, regardless of how it was produced (manually or by derivation).
This allows freely switching between using [fixed-output derivations](@docroot@/glossary.md#gloss-fixed-output-derivation) for fetching, and fetching out-of-band and then manually adding.
It also removes the ambiguity from the grammar.

# Quick Start
This chapter is for impatient people who don't like reading
documentation. For more in-depth information you are kindly referred
to subsequent chapters.
This chapter is for impatient people who don't like reading documentation.
For more in-depth information you are kindly referred to subsequent chapters.
1. Install Nix by running the following:
1. Install Nix:
```console
$ curl -L https://nixos.org/nix/install | sh
```
The install script will use `sudo`, so make sure you have sufficient rights.
On Linux, `--daemon` can be omitted for a single-user install.
For other installation methods, see [here](installation/index.md).
For other installation methods, see the detailed [installation instructions](installation/index.md).
1. See what installable packages are currently available in the
channel:
1. Run software without installing it permanently:
```console
$ nix-env --query --available --attr-path
nixpkgs.docbook_xml_dtd_43 docbook-xml-4.3
nixpkgs.docbook_xml_dtd_45 docbook-xml-4.5
nixpkgs.firefox firefox-33.0.2
nixpkgs.hello hello-2.9
nixpkgs.libxslt libxslt-1.1.28
…
$ nix-shell --packages cowsay lolcat
```
1. Install some packages from the channel:
This downloads the specified packages with all their dependencies, and drops you into a Bash shell where the commands provided by those packages are present.
This will not affect your normal environment:
```console
$ nix-env --install --attr nixpkgs.hello
[nix-shell:~]$ cowsay Hello, Nix! | lolcat
```
This should download pre-built packages; it should not build them
locally (if it does, something went wrong).
1. Test that they work:
Exiting the shell will make the programs disappear again:
```console
$ which hello
/home/eelco/.nix-profile/bin/hello
$ hello
Hello, world!
```
1. Uninstall a package:
```console
$ nix-env --uninstall hello
```
1. You can also test a package without installing it:
```console
$ nix-shell --packages hello
```
This builds or downloads GNU Hello and its dependencies, then drops
you into a Bash shell where the `hello` command is present, all
without affecting your normal environment:
```console
[nix-shell:~]$ hello
Hello, world!
[nix-shell:~]$ exit
$ hello
hello: command not found
$ lolcat
lolcat: command not found
```
1. To keep up-to-date with the channel, do:
1. Search for more packages on [search.nixos.org](https://search.nixos.org/) to try them out.
1. Free up storage space:
```console
$ nix-channel --update nixpkgs
$ nix-env --upgrade '*'
```
The latter command will upgrade each installed package for which
there is a “newer” version (as determined by comparing the version
numbers).
1. If you're unhappy with the result of a `nix-env` action (e.g., an
upgraded package turned out not to work properly), you can go back:
```console
$ nix-env --rollback
```
1. You should periodically run the Nix garbage collector to get rid of
unused packages, since uninstalls or upgrades don't actually delete
them:
```console
$ nix-collect-garbage --delete-old
$ nix-collect-garbage
```

# Release 2.20.0 (2024-01-29)
- Option `allowed-uris` can now match whole schemes in URIs without slashes [#9547](https://github.com/NixOS/nix/pull/9547)
If a scheme, such as `github:` is specified in the `allowed-uris` option, all URIs starting with `github:` are allowed.
Previously this only worked for schemes whose URIs used the `://` syntax.
- Include cgroup stats when building through the daemon [#9598](https://github.com/NixOS/nix/pull/9598)
Nix now also reports cgroup statistics when building through the Nix daemon and when doing remote builds using `ssh-ng`,
if both sides of the connection are using Nix 2.20 or newer.
- Disallow empty search regex in `nix search` [#9481](https://github.com/NixOS/nix/pull/9481)
[`nix search`](@docroot@/command-ref/new-cli/nix3-search.md) now requires a search regex to be passed. To show all packages, use `^`.
- Add new `eval-system` setting [#4093](https://github.com/NixOS/nix/pull/4093)
Add a new `eval-system` option.
Unlike `system`, it just overrides the value of `builtins.currentSystem`.
This is more useful than overriding `system`, because you can build these derivations on remote builders which can work on the given system.
In contrast, `system` also affects scheduling which will cause Nix to build those derivations locally even if that doesn't make sense.
`eval-system` only takes effect if it is non-empty.
If empty (the default) `system` is used as before, so there is no breakage.
- Import-from-derivation builds the derivation in the build store [#9661](https://github.com/NixOS/nix/pull/9661)
When using `--eval-store`, `import`ing from a derivation will now result in the derivation being built on the build store, i.e. the store specified in the `store` Nix option.
Because the resulting Nix expression must be copied back to the evaluation store in order to be imported, this requires the evaluation store to trust the build store's signatures.
- Mounted SSH Store [#7890](https://github.com/NixOS/nix/issues/7890) [#7912](https://github.com/NixOS/nix/pull/7912)
Introduced the store [`mounted-ssh-ng://`](@docroot@/command-ref/new-cli/nix3-help-stores.md).
This store allows full access to a Nix store on a remote machine and additionally requires that the store be mounted in the local filesystem.
- Rename `nix show-config` to `nix config show` [#7672](https://github.com/NixOS/nix/issues/7672) [#9477](https://github.com/NixOS/nix/pull/9477)
`nix show-config` was renamed to `nix config show`, and `nix doctor` was renamed to `nix config check`, to be more consistent with the rest of the command line interface.
- Add command `nix hash convert` [#9452](https://github.com/NixOS/nix/pull/9452)
This replaces the old `nix hash to-*` commands, which are still available but will emit a deprecation warning. Please convert as follows:
- `nix hash to-base16 $hash1 $hash2`: Use `nix hash convert --to base16 $hash1 $hash2` instead.
- `nix hash to-base32 $hash1 $hash2`: Use `nix hash convert --to nix32 $hash1 $hash2` instead.
- `nix hash to-base64 $hash1 $hash2`: Use `nix hash convert --to base64 $hash1 $hash2` instead.
- `nix hash to-sri $hash1 $hash2`: : Use `nix hash convert --to sri $hash1 $hash2` or even just `nix hash convert $hash1 $hash2` instead.
- Rename hash format `base32` to `nix32` [#9452](https://github.com/NixOS/nix/pull/9452)
Hash format `base32` was renamed to `nix32` since it used a special Nix-specific character set for
[Base32](https://en.wikipedia.org/wiki/Base32).
- `nix profile` now allows referring to elements by human-readable names [#8678](https://github.com/NixOS/nix/pull/8678)
[`nix profile`](@docroot@/command-ref/new-cli/nix3-profile.md) now uses names to refer to installed packages when running [`list`](@docroot@/command-ref/new-cli/nix3-profile-list.md), [`remove`](@docroot@/command-ref/new-cli/nix3-profile-remove.md) or [`upgrade`](@docroot@/command-ref/new-cli/nix3-profile-upgrade.md) as opposed to indices. Profile element names are generated when a package is installed and remain the same until the package is removed.
**Warning**: The `manifest.nix` file used to record the contents of profiles has changed. Nix will automatically upgrade profiles to the new version when you modify the profile. After that, the profile can no longer be used by older versions of Nix.
- Give `nix store add` a `--hash-algo` flag [#9809](https://github.com/NixOS/nix/pull/9809)
Adds a missing feature that was present in the old CLI, and matches our
plans to have similar flags for `nix hash convert` and `nix hash path`.
- Coercion errors include the failing value
The `error: cannot coerce a <TYPE> to a string` message now includes the value
which caused the error.
Before:
```
error: cannot coerce a set to a string
```
After:
```
error: cannot coerce a set to a string: { aesSupport = «thunk»;
avx2Support = «thunk»; avx512Support = «thunk»; avxSupport = «thunk»;
canExecute = «thunk»; config = «thunk»; darwinArch = «thunk»; darwinMinVersion
= «thunk»; darwinMinVersionVariable = «thunk»; darwinPlatform = «thunk»; «84
attributes elided»}
```
- Type errors include the failing value
In errors like `value is an integer while a list was expected`, the message now
includes the failing value.
Before:
```
error: value is a set while a string was expected
```
After:
```
error: expected a string but found a set: { ghc810 = «thunk»;
ghc8102Binary = «thunk»; ghc8107 = «thunk»; ghc8107Binary = «thunk»;

ghc924Binary = «thunk»; ghc925 = «thunk»; «17 attributes elided»}
```
- Source locations are printed more consistently in errors [#561](https://github.com/NixOS/nix/issues/561) [#9555](https://github.com/NixOS/nix/pull/9555)
Source location information is now included in error messages more
consistently. Given this code:
```nix
let
attr = {foo = "bar";};
key = {};
in
attr.${key}
```
Previously, Nix would show this unhelpful message when attempting to evaluate
it:
```
error:
… while evaluating an attribute name
error: value is a set while a string was expected
```
Now, the error message displays where the problematic value was found:
```
error:
… while evaluating an attribute name
at bad.nix:4:11:
3| key = {};
4| in attr.${key}
| ^
5|
error: expected a string but found a set
```
- Some stack overflow segfaults are fixed [#9616](https://github.com/NixOS/nix/issues/9616) [#9617](https://github.com/NixOS/nix/pull/9617)
The number of nested function calls has been restricted, to detect and report
infinite function call recursions. The default maximum call depth is 10,000 and
can be set with [the `max-call-depth`
option](@docroot@/command-ref/conf-file.md#conf-max-call-depth).
This replaces the `stack overflow (possible infinite recursion)` message.
- Better error reporting for `with` expressions [#9658](https://github.com/NixOS/nix/pull/9658)
`with` expressions using non-attrset values to resolve variables are now reported with proper positions, e.g.
```
nix-repl> with 1; a
error:
… while evaluating the first subexpression of a with expression
at «string»:1:1:
1| with 1; a
| ^
error: expected a set but found an integer
```
- Functions are printed with more detail [#7145](https://github.com/NixOS/nix/issues/7145) [#9606](https://github.com/NixOS/nix/pull/9606)
`nix repl`, `nix eval`, `builtins.trace`, and most other places values are
printed will now include function names and source location information:
```
$ nix repl nixpkgs
nix-repl> builtins.map
«primop map»
nix-repl> builtins.map lib.id
«partially applied primop map»
nix-repl> builtins.trace lib.id "my-value"
trace: «lambda id @ /nix/store/8rrzq23h2zq7sv5l2vhw44kls5w0f654-source/lib/trivial.nix:26:5»
"my-value"
```
- Flake operations like `nix develop` will no longer fail when run in a Git
repository where the `flake.lock` file is `.gitignore`d
[#8854](https://github.com/NixOS/nix/issues/8854)
[#9324](https://github.com/NixOS/nix/pull/9324)
- Nix commands will now respect Ctrl-C
[#7145](https://github.com/NixOS/nix/issues/7145)
[#6995](https://github.com/NixOS/nix/pull/6995)
[#9687](https://github.com/NixOS/nix/pull/9687)
Previously, many Nix commands would hang indefinitely if Ctrl-C was pressed
while performing various operations (including `nix develop`, `nix flake
update`, and so on). With several fixes to Nix's signal handlers, Nix
commands will now exit quickly after Ctrl-C is pressed.

# Release 2.21.0 (2024-03-11)
- Fix a fixed-output derivation sandbox escape (CVE-2024-27297)
Cooperating Nix derivations could send file descriptors to files in the Nix
store to each other via Unix domain sockets in the abstract namespace. This
allowed one derivation to modify the output of the other derivation, after Nix
has registered the path as "valid" and immutable in the Nix database.
In particular, this allowed the output of fixed-output derivations to be
modified from their expected content.
This isn't the case any more.
- CLI options `--arg-from-file` and `--arg-from-stdin` [#10122](https://github.com/NixOS/nix/pull/10122)
The new CLI option `--arg-from-file` *name* *path* passes the contents
of file *path* as a string value via the function argument *name* to a
Nix expression. Similarly, the new option `--arg-from-stdin` *name*
reads the contents of the string from standard input.
- Concise error printing in `nix repl` [#9928](https://github.com/NixOS/nix/pull/9928)
Previously, if an element of a list or attribute set threw an error while
evaluating, `nix repl` would print the entire error (including source location
information) inline. This output was clumsy and difficult to parse:
```
nix-repl> { err = builtins.throw "uh oh!"; }
{ err = «error:
… while calling the 'throw' builtin
at «string»:1:9:
1| { err = builtins.throw "uh oh!"; }
| ^
error: uh oh!»; }
```
Now, only the error message is displayed, making the output much more readable.
```
nix-repl> { err = builtins.throw "uh oh!"; }
{ err = «error: uh oh!»; }
```
However, if the whole expression being evaluated throws an error, source
locations and (if applicable) a stack trace are printed, just like you'd expect:
```
nix-repl> builtins.throw "uh oh!"
error:
… while calling the 'throw' builtin
at «string»:1:1:
1| builtins.throw "uh oh!"
| ^
error: uh oh!
```
- `--debugger` can now access bindings from `let` expressions [#8827](https://github.com/NixOS/nix/issues/8827) [#9918](https://github.com/NixOS/nix/pull/9918)
Breakpoints and errors in the bindings of a `let` expression can now access
those bindings in the debugger. Previously, only the body of `let` expressions
could access those bindings.
- Enter the `--debugger` when `builtins.trace` is called if `debugger-on-trace` is set [#9914](https://github.com/NixOS/nix/pull/9914)
If the `debugger-on-trace` option is set and `--debugger` is given,
`builtins.trace` calls will behave similarly to `builtins.break` and will enter
the debug REPL. This is useful for determining where warnings are being emitted
from.
- Debugger prints source position information [#9913](https://github.com/NixOS/nix/pull/9913)
The `--debugger` now prints source location information, instead of the
pointers of source location information. Before:
```
nix-repl> :bt
0: while evaluating the attribute 'python311.pythonForBuild.pkgs'
0x600001522598
```
After:
```
0: while evaluating the attribute 'python311.pythonForBuild.pkgs'
/nix/store/hg65h51xnp74ikahns9hyf3py5mlbbqq-source/overrides/default.nix:132:27
131|
132| bootstrappingBase = pkgs.${self.python.pythonAttr}.pythonForBuild.pkgs;
| ^
133| in
```
- The `--debugger` will start more reliably in `let` expressions and function calls [#6649](https://github.com/NixOS/nix/issues/6649) [#9917](https://github.com/NixOS/nix/pull/9917)
Previously, if you attempted to evaluate this file with the debugger:
```nix
let
a = builtins.trace "before inner break" (
builtins.break "hello"
);
b = builtins.trace "before outer break" (
builtins.break a
);
in
b
```
Nix would correctly enter the debugger at `builtins.break a`, but if you asked
it to `:continue`, it would skip over the `builtins.break "hello"` expression
entirely.
Now, Nix will correctly enter the debugger at both breakpoints.
- Nested debuggers are no longer supported [#9920](https://github.com/NixOS/nix/pull/9920)
Previously, evaluating an expression that throws an error in the debugger would
enter a second, nested debugger:
```
nix-repl> builtins.throw "what"
error: what
Starting REPL to allow you to inspect the current state of the evaluator.
Welcome to Nix 2.18.1. Type :? for help.
nix-repl>
```
Now, it just prints the error message like `nix repl`:
```
nix-repl> builtins.throw "what"
error:
… while calling the 'throw' builtin
at «string»:1:1:
1| builtins.throw "what"
| ^
error: what
```
- Consistent order of function arguments in printed expressions [#9874](https://github.com/NixOS/nix/pull/9874)
Function arguments are now printed in lexicographic order rather than the internal, creation-time based symbol order.
- Fix duplicate attribute error positions for `inherit` [#9874](https://github.com/NixOS/nix/pull/9874)
When an `inherit` caused a duplicate attribute error the position of the error was not reported correctly, placing the error with the inherit itself or at the start of the bindings block instead of the offending attribute name.
- `inherit (x) ...` evaluates `x` only once [#9847](https://github.com/NixOS/nix/pull/9847)
`inherit (x) a b ...` now evaluates the expression `x` only once for all inherited attributes rather than once for each inherited attribute.
This does not usually have a measurable impact, but side-effects (such as `builtins.trace`) would be duplicated and expensive expressions (such as derivations) could cause a measurable slowdown.
- Store paths are allowed to start with `.` [#912](https://github.com/NixOS/nix/issues/912) [#9091](https://github.com/NixOS/nix/pull/9091) [#9095](https://github.com/NixOS/nix/pull/9095) [#9120](https://github.com/NixOS/nix/pull/9120) [#9121](https://github.com/NixOS/nix/pull/9121) [#9122](https://github.com/NixOS/nix/pull/9122) [#9130](https://github.com/NixOS/nix/pull/9130) [#9219](https://github.com/NixOS/nix/pull/9219) [#9224](https://github.com/NixOS/nix/pull/9224) [#9867](https://github.com/NixOS/nix/pull/9867)
Leading periods were allowed by accident in Nix 2.4. The Nix team has considered this to be a bug, but this behavior has since been relied on by users, leading to unnecessary difficulties.
From now on, leading periods are supported. The names `.` and `..` are disallowed, as well as those starting with `.-` or `..-`.
Nix versions that denied leading periods are documented [in the issue](https://github.com/NixOS/nix/issues/912#issuecomment-1919583286).
- `nix repl` pretty-prints values [#9931](https://github.com/NixOS/nix/pull/9931)
`nix repl` will now pretty-print values:
```
{
attrs = {
a = {
b = {
c = { };
};
};
};
list = [ 1 ];
list' = [
1
2
3
];
}
```
- Introduction of `--regex` and `--all` in `nix profile remove` and `nix profile upgrade` [#10166](https://github.com/NixOS/nix/pull/10166)
Previously the command-line arguments for `nix profile remove` and `nix profile upgrade` matched the package entries using regular expression.
For instance:
```
nix profile remove '.*vim.*'
```
This would remove all packages that contain `vim` in their name.
In most cases, only singular package names were used to remove and upgrade packages. Mixing this with regular expressions sometimes lead to unintended behavior. For instance, `python3.1` could match `python311`.
To avoid unintended behavior, the arguments are now only matching exact names.
Matching using regular expressions is still possible by using the new `--regex` flag:
```
nix profile remove --regex '.*vim.*'
```
One of the most useful cases for using regular expressions was to upgrade all packages. This was previously accomplished by:
```
nix profile upgrade '.*'
```
With the introduction of the `--all` flag, this now becomes more straightforward:
```
nix profile upgrade --all
```
- Visual clutter in `--debugger` is reduced [#9919](https://github.com/NixOS/nix/pull/9919)
Before:
```
info: breakpoint reached
Starting REPL to allow you to inspect the current state of the evaluator.
Welcome to Nix 2.20.0pre20231222_dirty. Type :? for help.
nix-repl> :continue
error: uh oh
Starting REPL to allow you to inspect the current state of the evaluator.
Welcome to Nix 2.20.0pre20231222_dirty. Type :? for help.
nix-repl>
```
After:
```
info: breakpoint reached
Nix 2.20.0pre20231222_dirty debugger
Type :? for help.
nix-repl> :continue
error: uh oh
nix-repl>
```
- Cycle detection in `nix repl` is simpler and more reliable [#8672](https://github.com/NixOS/nix/issues/8672) [#9926](https://github.com/NixOS/nix/pull/9926)
The cycle detection in `nix repl`, `nix eval`, `builtins.trace`, and everywhere
else values are printed is now simpler and matches the cycle detection in
`nix-instantiate --eval` output.
Before:
```
nix eval --expr 'let self = { inherit self; }; in self'
{ self = { self = «repeated»; }; }
```
After:
```
{ self = «repeated»; }
```
- In the debugger, `while evaluating the attribute` errors now include position information [#9915](https://github.com/NixOS/nix/pull/9915)
Before:
```
0: while evaluating the attribute 'python311.pythonForBuild.pkgs'
0x600001522598
```
After:
```
0: while evaluating the attribute 'python311.pythonForBuild.pkgs'
/nix/store/hg65h51xnp74ikahns9hyf3py5mlbbqq-source/overrides/default.nix:132:27
131|
132| bootstrappingBase = pkgs.${self.python.pythonAttr}.pythonForBuild.pkgs;
| ^
133| in
```
- Stack size is increased on macOS [#9860](https://github.com/NixOS/nix/pull/9860)
Previously, Nix would set the stack size to 64MiB on Linux, but would leave the
stack size set to the default (approximately 8KiB) on macOS. Now, the stack
size is correctly set to 64MiB on macOS as well, which should reduce stack
overflow segfaults in deeply-recursive Nix expressions.
