synopsis: Define integer overflow in the Nix language as an error
|
||||
issues: [10968]
|
||||
prs: [11188]
|
||||
---
|
||||
|
||||
Previously, integer overflow in the Nix language invoked C++ level signed overflow, which was undefined behaviour, but *usually* manifested as wrapping around on overflow.
|
||||
|
||||
Since prior to the public release of Lix, Lix had C++ signed overflow defined to crash the process and nobody noticed this having accidentally removed overflow from the Nix language for three months until it was caught by fiddling around.
|
||||
Given the significant body of actual Nix code that has been evaluated by Lix in that time, it does not appear that nixpkgs or much of importance depends on integer overflow, so it appears safe to turn into an error.
|
||||
|
||||
Some other overflows were fixed:
|
||||
- `builtins.fromJSON` of values greater than the maximum representable value in a signed 64-bit integer will generate an error.
|
||||
- `nixConfig` in flakes will no longer accept negative values for configuration options.
|
||||
|
||||
Integer overflow now looks like the following:
|
||||
|
||||
```
|
||||
$ nix eval --expr '9223372036854775807 + 1'
|
||||
error: integer overflow in adding 9223372036854775807 + 1
|
||||
```

The `build-hook` setting's default is less useful when using `libnixstore` as a library
|

prs:

---
|
||||
|
||||
*This is an obscure issue that only affects usage of the `libnixstore` library outside of the Nix executable.*
|
||||
|
||||
As part the ongoing [rewrite of the build system](https://github.com/NixOS/nix/issues/2503) to use [Meson](https://mesonbuild.com/), we are also switching to packaging individual Nix components separately (and building them in separate derivations).
|
||||
This means that when building `libnixstore` we do not know where the Nix binaries will be installed --- `libnixstore` doesn't know about downstream consumers like the Nix binaries at all.
|
||||
|
||||
*This is also unrelated to the _`post`_-`build-hook`*, which is often used for pushing to a cache.*
|
||||
|
||||
This has a small adverse affect on remote building --- the `build-remote` executable that is specified from the [`build-hook`](@docroot@/command-ref/conf-file.md#conf-build-hook) setting will not be gotten from the (presumed) installation location, but instead looked up on the `PATH`.
|
||||
This means that other applications linking `libnixstore` that wish to use remote building must arrange for the `nix` command to be on the PATH (or manually overriding `build-hook`) in order for that to work.
|
||||
|
||||
Long term we don't envision this being a downside, because we plan to [get rid of `build-remote` and the build hook setting entirely](https://github.com/NixOS/nix/issues/1221).
|
||||
There is simply no need to add a second layer of remote-procedure-calling when we want to connect to a remote builder.
|
||||
The build hook protocol did in principle support custom ways of remote building, but that can also be accomplished with a custom service for the ssh or daemon/ssh-ng protocols, or with a custom [store type](@docroot@/store/types/) i.e. `Store` subclass. <!-- we normally don't mention classes, but consider that this release note is about a library use case -->
|
||||
|
||||
The Perl bindings no longer expose `getBinDir` either, since they libraries those bindings wrap no longer know the location of installed binaries as described above.

`nix-shell $x` now looks for `$x/shell.nix` when `$x` resolves to a directory.
|
||||
|
||||
Although this might be seen as a breaking change, its primarily interactive usage makes it a minor issue.
|
||||
This adjustment addresses a commonly reported problem.
|
||||
|
||||
This also applies to `nix-shell` shebang scripts. Consider the following example:
|
||||
|
||||
```shell
|
||||
#!/usr/bin/env nix-shell
|
||||
#!nix-shell -i bash
|
||||
```
|
||||
|
||||
This will now load `shell.nix` from the script's directory, if it exists; `default.nix` otherwise.
|
||||
|
||||
The old behavior can be opted into by setting the option [`nix-shell-always-looks-for-shell-nix`](@docroot@/command-ref/conf-file.md#conf-nix-shell-always-looks-for-shell-nix) to `false`.

`nix repl` has a `:doc` command that previously only rendered documentation for internally defined functions.
|
||||
This feature has been extended to also render function documentation comments, in accordance with [RFC 145].
|
||||
|
||||
Example:
|
||||
|
||||
```
|
||||
nix-repl> :doc lib.toFunction
|
||||
Function toFunction
|
||||
… defined at /home/user/h/nixpkgs/lib/trivial.nix:1072:5
|
||||
|
||||
Turns any non-callable values into constant functions. Returns
|
||||
callable values as is.
|
||||
|
||||
Inputs
|
||||
|
||||
v
|
||||
|
||||
: Any value
|
||||
|
||||
Examples
|
||||
|
||||
:::{.example}
|
||||
|
||||
## lib.trivial.toFunction usage example
|
||||
|
||||
| nix-repl> lib.toFunction 1 2
|
||||
| 1
|
||||
|
|
||||
| nix-repl> lib.toFunction (x: x + 1) 2
|
||||
| 3
|
||||
|
||||
:::
|
||||
```
|
||||
|
||||
Known limitations:
|
||||
- It does not render documentation for "formals", such as `{ /** the value to return */ x, ... }: x`.
|
||||
- Some extensions to markdown are not yet supported, as you can see in the example above.
|
||||
|
||||
We'd like to acknowledge Yingchi Long for proposing a proof of concept for this functionality in [#9054](https://github.com/NixOS/nix/pull/9054), as well as @sternenseemann and Johannes Kirschbauer for their contributions, proposals, and their work on [RFC 145].

<!-- unfortunately no link target for the specific syntax -->
|
||||
Relative [path](@docroot@/language/values.md#type-path) literals in `nix-shell` shebang scripts' options are now resolved relative to the [script's location](@docroot@/glossary?highlight=base%20directory#gloss-base-directory).
|
||||
Previously they were resolved relative to the current working directory.
|
||||
|
||||
For example, consider the following script in `~/myproject/say-hi`:
|
||||
|
||||
```shell
|
||||
#!/usr/bin/env nix-shell
|
||||
#!nix-shell --expr 'import ./shell.nix'
|
||||
#!nix-shell --arg toolset './greeting-tools.nix'
|
||||
#!nix-shell -i bash
|
||||
hello
|
||||
```
|
||||
|
||||
Older versions of `nix-shell` would resolve `shell.nix` relative to the current working directory; home in this example:
|
||||
|
||||
```console
|
||||
[hostname:~]$ ./myproject/say-hi
|
||||
error:
|
||||
… while calling the 'import' builtin
|
||||
at «string»:1:2:
|
||||
1| (import ./shell.nix)
|
||||
| ^
|
||||
|
||||
error: path '/home/user/shell.nix' does not exist
|
||||
```
|
||||
|
||||
Since this release, `nix-shell` resolves `shell.nix` relative to the script's location, and `~/myproject/shell.nix` is used.
|
||||
|
||||
```console
|
||||
$ ./myproject/say-hi
|
||||
Hello, world!
|
||||
```
|
||||
|
||||
**Opt-out**
|
||||
|
||||
This is technically a breaking change, so we have added an option so you can adapt independently of your Nix update.
|
||||
The old behavior can be opted into by setting the option [`nix-shell-shebang-arguments-relative-to-script`](@docroot@/command-ref/conf-file.md#conf-nix-shell-shebang-arguments-relative-to-script) to `false`.
|
||||
This option will be removed in a future release.
|
||||
|
||||
**`nix` command shebang**
|
||||
|
||||
The experimental [`nix` command shebang](@docroot@/command-ref/new-cli/nix.md?highlight=shebang#shebang-interpreter) already behaves in this script-relative manner.
|
||||
|
||||
Example:
|
||||
|
||||
```shell
|
||||
#!/usr/bin/env nix
|
||||
#!nix develop
|
||||
#!nix --expr ``import ./shell.nix``
|
||||
#!nix -c bash
|
||||
hello
|
||||
```

### Build process
|
||||
|
||||
Releases have a precomputed `rl-MAJOR.MINOR.md`, and no `rl-next.md`.
|
||||
|
||||
## 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)
|
||||
|
||||
- [`latest-release`](https://github.com/NixOS/nix/tree/latest-release)
|
||||
|
||||
The latest patch release of the latest minor version.
|
||||
|
||||
See [`maintainers/release-process.md`](https://github.com/NixOS/nix/blob/master/maintainers/release-process.md)
|
||||
|
||||
- [`backport-*-to-*`](https://github.com/NixOS/nix/branches/all?query=backport)
|
||||
|
||||
Generally branches created by the backport action.
|
||||
|
||||
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.

# Identifiers
|
||||
|
||||
An *identifier* is an [ASCII](https://en.wikipedia.org/wiki/ASCII) character sequence that:
|
||||
- Starts with a letter (`a-z`, `A-Z`) or underscore (`_`)
|
||||
- Can contain any number of:
|
||||
- Letters (`a-z`, `A-Z`)
|
||||
- Digits (`0-9`)
|
||||
- Underscores (`_`)
|
||||
- Apostrophes (`'`)
|
||||
- Hyphens (`-`)
|
||||
- Is not one of the [keywords](#keywords)
|
||||
|
||||
> **Syntax**
|
||||
>
|
||||
> *identifier* ~ `[A-Za-z_][A-Za-z0-9_'-]*`
|
||||
|
||||
# Names
|
||||
|
||||
A *name* can be written as an [identifier](#identifier) or a [string literal](./string-literals.md).
|
||||
|
||||
> **Syntax**
|
||||
>
|
||||
> *name* → *identifier* | *string*
|
||||
|
||||
Names are used in [attribute sets](./syntax.md#attrs-literal), [`let` bindings](./syntax.md#let-expressions), and [`inherit`](./syntax.md#inheriting-attributes).
|
||||
Two names are the same if they represent the same sequence of characters, regardless of whether they are written as identifiers or strings.

||||
|
||||
# Keywords

# Scoping rules
|
||||
|
||||
Nix is [statically scoped](https://en.wikipedia.org/wiki/Scope_(computer_science)#Lexical_scope), but with multiple scopes and shadowing rules.
|
||||
A *scope* in the Nix language is a dictionary keyed by [name](./identifiers.md#names), mapping each name to an expression and a *definition type*.
|
||||
The definition type is either *explicit* or *implicit*.
|
||||
Each entry in this dictionary is a *definition*.
|
||||
|
||||
* primary scope: explicitly-bound variables
|
||||
* [`let`](./syntax.md#let-expressions)
|
||||
* [`inherit`](./syntax.md#inheriting-attributes)
|
||||
* [function](./syntax.md#functions) arguments
|
||||
Explicit definitions are created by the following expressions:
|
||||
- [let-expressions](syntax.md#let-expressions)
|
||||
- [recursive attribute set literals](syntax.md#recursive-sets) (`rec`)
|
||||
- [function literals](syntax.md#functions)
|
||||
|
||||
* secondary scope: implicitly-bound variables
|
||||
* [`with`](./syntax.md#with-expressions)
|
||||
Implicit definitions are only created by [with-expressions](./syntax.md#with-expressions).
|
||||
|
||||
Primary scope takes precedence over secondary scope.
|
||||
See [`with`](./syntax.md#with-expressions) for a detailed example.
|
||||
Every expression is *enclosed* by a scope.
|
||||
The outermost expression is enclosed by the [built-in, global scope](./builtins.md), which contains only explicit definitions.
|
||||
The expressions listed above *extend* their enclosing scope by adding new definitions, or replacing existing ones with the same name.
|
||||
An explicit definition can replace a definition of any type; an implicit definition can only replace another implicit definition.
|
||||
|
||||
Each of the above expressions defines which of its subexpressions are enclosed by the extended scope.
|
||||
In all other cases, the same scope that encloses an expression is the enclosing scope for its subexpressions.
|
||||
|
||||
The Nix language is [statically scoped](https://en.wikipedia.org/wiki/Scope_(computer_science)#Lexical_scope);
|
||||
the value of a variable is determined only by the variable's enclosing scope, and not by the dynamic context in which the variable is evaluated.

||||
|
||||
> **Note**
|
||||
>
|
||||
> Expressions entered into the [Nix REPL](@docroot@/command-ref/new-cli/nix3-repl.md) are enclosed by a scope that can be extended by command line arguments or previous REPL commands.

|
||||
|
||||
Strings can be written in three ways.
|
||||
|
||||
The most common way is to enclose the string between double quotes, e.g., `"foo bar"`.
|
||||
Strings can span multiple lines.
|
||||
The results of other expressions can be included into a string by enclosing them in `${ }`, a feature known as [string interpolation].
|
||||
|
||||
[string interpolation]: ./string-interpolation.md
|
||||
|
||||
The following must be escaped to represent them within a string, by prefixing with a backslash (`\`):
|
||||
|
||||
- Double quote (`"`)
|
||||
|
||||
> **Example**
|
||||
>
|
||||
> ```nix
|
||||
> "\""
|
||||
> ```
|
||||
>
|
||||
> "\""
|
||||
|
||||
- Backslash (`\`)
|
||||
|
||||
> **Example**
|
||||
>
|
||||
> ```nix
|
||||
> "\\"
|
||||
> ```
|
||||
>
|
||||
> "\\"
|
||||
|
||||
- Dollar sign followed by an opening curly bracket (`${`) – "dollar-curly"
|
||||
|
||||
> **Example**
|
||||
>
|
||||
> ```nix
|
||||
> "\${"
|
||||
> ```
|
||||
>
|
||||
> "\${"
|
||||
|
||||
The newline, carriage return, and tab characters can be written as `\n`, `\r` and `\t`, respectively.
|
||||
|
||||
A "double-dollar-curly" (`$${`) can be written literally.
|
||||
|
||||
> **Example**
|
||||
>
|
||||
> ```nix
|
||||
> "$${"
|
||||
> ```
|
||||
>
|
||||
> "$\${"
|
||||
|
||||
String values are output on the terminal with Nix-specific escaping.
|
||||
Strings written to files will contain the characters encoded by the escaping.
|
||||
|
||||
The second way to write string literals is as an *indented string*, which is enclosed between pairs of *double single-quotes* (`''`), like so:
|
||||
|
||||
```nix
|
||||
''
|
||||
This is the first line.
|
||||
This is the second line.
|
||||
This is the third line.
|
||||
''
|
||||
```
|
||||
|
||||
This kind of string literal intelligently strips indentation from
|
||||
the start of each line. To be precise, it strips from each line a
|
||||
number of spaces equal to the minimal indentation of the string as a
|
||||
whole (disregarding the indentation of empty lines). For instance,
|
||||
the first and second line are indented two spaces, while the third
|
||||
line is indented four spaces. Thus, two spaces are stripped from
|
||||
each line, so the resulting string is
|
||||
|
||||
```nix
|
||||
"This is the first line.\nThis is the second line.\n This is the third line.\n"
|
||||
```
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Whitespace and newline following the opening `''` is ignored if there is no non-whitespace text on the initial line.
|
||||
|
||||
> **Warning**
|
||||
>
|
||||
> Prefixed tab characters are not stripped.
|
||||
>
|
||||
> > **Example**
|
||||
> >
|
||||
> > The following indented string is prefixed with tabs:
|
||||
> >
|
||||
> > <pre><code class="nohighlight">''
|
||||
> > all:
|
||||
> > @echo hello
|
||||
> > ''
|
||||
> > </code></pre>
|
||||
> >
|
||||
> > "\tall:\n\t\t@echo hello\n"
|
||||
|
||||
Indented strings support [string interpolation].
|
||||
|
||||
The following must be escaped to represent them in an indented string:
|
||||
|
||||
- `$` is escaped by prefixing it with two single quotes (`''`)
|
||||
|
||||
> **Example**
|
||||
>
|
||||
> ```nix
|
||||
> ''
|
||||
> ''$
|
||||
> ''
|
||||
> ```
|
||||
>
|
||||
> "$\n"
|
||||
|
||||
- `''` is escaped by prefixing it with one single quote (`'`)
|
||||
|
||||
> **Example**
|
||||
>
|
||||
> ```nix
|
||||
> ''
|
||||
> '''
|
||||
> ''
|
||||
> ```
|
||||
>
|
||||
> "''\n"
|
||||
|
||||
These special characters are escaped as follows:
|
||||
- Linefeed (`\n`): `''\n`
|
||||
- Carriage return (`\r`): `''\r`
|
||||
- Tab (`\t`): `''\t`
|
||||
|
||||
`''\` escapes any other character.
|
||||
|
||||
A "double-dollar-curly" (`$${`) can be written literally.
|
||||
|
||||
> **Example**
|
||||
>
|
||||
> ```nix
|
||||
> ''
|
||||
> $${
|
||||
> ''
|
||||
> ```
|
||||
>
|
||||
> "$\${\n"
|
||||
|
||||
Indented strings are primarily useful in that they allow multi-line
|
||||
string literals to follow the indentation of the enclosing Nix
|
||||
expression, and that less escaping is typically necessary for
|
||||
strings representing languages such as shell scripts and
|
||||
configuration files because `''` is much less common than `"`.
|
||||
Example:
|
||||
|
||||
```nix
|
||||
stdenv.mkDerivation {
|
||||
...
|
||||
postInstall =
|
||||

[RFC 2396](http://www.ietf.org/rfc/rfc2396.txt) can be written *as

`http://example.org/foo.tar.bz2`.

Integers in the Nix language are 64-bit [two's complement] signed integers, with a range of -9223372036854775808 to 9223372036854775807, inclusive.

|

Note that negative numeric literals are actually parsed as unary negation of positive numeric literals.
|
||||
This means that the minimum integer `-9223372036854775808` cannot be written as-is as a literal, since the positive number `9223372036854775808` is one past the maximum range.

An attribute set is a collection of name-value-pairs (called *attributes*) enclosed in curly brackets (`{ }`).
|
||||
An attribute set is a collection of name-value-pairs called *attributes*.
|
||||
|
||||
An attribute name can be an identifier or a [string](#string).
|
||||
An identifier must start with a letter (`a-z`, `A-Z`) or underscore (`_`), and can otherwise contain letters (`a-z`, `A-Z`), numbers (`0-9`), underscores (`_`), apostrophes (`'`), or dashes (`-`).
|
||||
Attribute sets are written enclosed in curly brackets (`{ }`).
|
||||
Attribute names and attribute values are separated by an equal sign (`=`).
|
||||
Each value can be an arbitrary expression, terminated by a semicolon (`;`)
|
||||
|
||||
An attribute name is a string without context, and is denoted by a [name] (an [identifier](./identifiers.md#identifiers) or [string literal](string-literals.md)).
|
||||
|
||||
[name]: ./identifiers.md#names
|
||||
|

Attributes in nested attribute sets can be written using *attribute paths*.

# Release 2.24.0 (2024-07-31)
|
||||
|
||||
### Significant changes
|
||||
|
||||
- Harden user sandboxing
|
||||
|
||||
The build directory has been hardened against interference with the outside world by nesting it inside another directory owned by (and only readable by) the daemon user.
|
||||
|
||||
This is a low severity security fix, [CVE-2024-38531](https://www.cve.org/CVERecord?id=CVE-2024-38531).

|
||||
|
||||
`nix-shell $x` now looks for `$x/shell.nix` when `$x` resolves to a directory.
|
||||
|
||||
Although this might be seen as a breaking change, its primarily interactive usage makes it a minor issue.
|
||||
This adjustment addresses a commonly reported problem.
|
||||
|
||||
This also applies to `nix-shell` shebang scripts. Consider the following example:
|
||||
|
||||
```shell
|
||||
#!/usr/bin/env nix-shell
|
||||
#!nix-shell -i bash
|
||||
```
|
||||
|
||||
This will now load `shell.nix` from the script's directory, if it exists; `default.nix` otherwise.
|
||||
|
||||
The old behavior can be opted into by setting the option [`nix-shell-always-looks-for-shell-nix`](@docroot@/command-ref/conf-file.md#conf-nix-shell-always-looks-for-shell-nix) to `false`.

`nix repl` has a `:doc` command that previously only rendered documentation for internally defined functions.
|
||||
This feature has been extended to also render function documentation comments, in accordance with [RFC 145].

Known limitations:

- It does not render documentation for "formals", such as `{ /** the value to return */ x, ... }: x`.

- Some extensions to markdown are not yet supported, as you can see in the example above.

This eliminates all "cached failure of attribute X" messages by forcing evaluation of the original value when needed to show the exception to the user. This enhancement improves error reporting by providing the underlying message and stack trace.

||||

Currently, the action runs the first 25 flakes due to the full test suite's extensive runtime. A manually triggered action may be implemented later to run the entire test suite.

- Support unit prefixes in configuration settings [#10668](https://github.com/NixOS/nix/pull/10668)
|
||||
|
||||
Configuration settings in Nix now support unit prefixes, allowing for more intuitive and readable configurations. For example, you can now specify [`--min-free 1G`](@docroot@/command-ref/opt-common.md#opt-min-free) to set the minimum free space to 1 gigabyte.

|
||||

- `nix build`: show all FOD errors with `--keep-going` [#10734](https://github.com/NixOS/nix/pull/10734)
|
||||
|
||||
The [`nix build`](@docroot@/command-ref/new-cli/nix3-build.md) command has been updated to improve the behavior of the [`--keep-going`] flag. Now, when `--keep-going` is used, all hash-mismatch errors of failing fixed-output derivations (FODs) are displayed, similar to the behavior for other build failures. This enhancement ensures that all relevant build errors are shown, making it easier for users to update multiple derivations at once or to diagnose and fix issues.

These changes aim to replace the use of autotools and `make` with Meson for building various components of Nix. Additionally, each library is built in its own derivation, leveraging Meson's "subprojects" feature to allow a single development shell for building all libraries while also supporting separate builds. This approach aims to improve productivity and build modularity, compared to both make and a monolithic Meson-based derivation.
|
||||
|
||||
Special thanks to everyone who has contributed to the Meson port, particularly [**@p01arst0rm**](https://github.com/p01arst0rm) and [**@Qyriad**](https://github.com/Qyriad).

- Evaluation cache: fix cache regressions [#10570](https://github.com/NixOS/nix/issues/10570) [#11086](https://github.com/NixOS/nix/pull/11086)
|
||||
|
||||
This update addresses two bugs in the evaluation cache system:
|
||||
|
||||
1. Regression in #10570: The evaluation cache was not being persisted in `nix develop`.
|
||||
2. Nix could sometimes try to commit the evaluation cache SQLite transaction without there being an active transaction, resulting in non-error errors being printed.

- Introduce `libnixflake` [#9063](https://github.com/NixOS/nix/pull/9063)
|
||||
|
||||
A new library, `libnixflake`, has been introduced to better separate the Flakes layer within Nix. This change refactors the codebase to encapsulate Flakes-specific functionality within its own library.
|
||||
|
||||
See the commits in the pull request for detailed changes, with the only significant code modifications happening in the initial commit.
|
||||
|
||||
This change was alluded to in [RFC 134](https://github.com/nixos/rfcs/blob/master/rfcs/0134-nix-store-layer.md) and is a step towards a more modular and maintainable codebase.

- Stop vendoring `toml11`
|

We don't apply any patches to it, and vendoring it locks users into

bugs (it hasn't been updated since its introduction in late 2021).

- Rename hash format `base32` to `nix32` [#8678](https://github.com/NixOS/nix/pull/8678)
|
||||
|
||||
Hash format `base32` was renamed to `nix32` since it used a special nix-specific character set for
|
||||
[Base32](https://en.wikipedia.org/wiki/Base32).
|
||||
|
||||
**Deprecation**: Use `nix32` instead of `base32` as `toHashFormat`
|
||||
|
||||
For the builtin `convertHash`, the `toHashFormat` parameter now accepts the same hash formats as the `--to`/`--from`
|
||||
parameters of the `nix hash conert` command: `"base16"`, `"nix32"`, `"base64"`, and `"sri"`. The former `"base32"` value
|
||||
remains as a deprecated alias for `"nix32"`. Please convert your code from:
|
||||
|
||||
```nix
|
||||
builtins.convertHash { inherit hash hashAlgo; toHashFormat = "base32";}
|
||||
```
|
||||
|
||||
to
|
||||
|
||||
```nix
|
||||
builtins.convertHash { inherit hash hashAlgo; toHashFormat = "nix32";}
|
||||
```
|
||||
|
||||
- Add `pipe-operators` experimental feature [#11131](https://github.com/NixOS/nix/pull/11131)
|
||||
|
||||
This is a draft implementation of [RFC 0148](https://github.com/NixOS/rfcs/pull/148).
|
||||
|
||||
The `pipe-operators` experimental feature adds [`<|` and `|>` operators][pipe operators] to the Nix language.
|
||||
*a* `|>` *b* is equivalent to the function application *b* *a*, and
|
||||
*a* `<|` *b* is equivalent to the function application *a* *b*.
|
||||
|
||||
For example:
|
||||
|
||||
```
|
||||
nix-repl> 1 |> builtins.add 2 |> builtins.mul 3
|
||||
9
|
||||
|
||||
nix-repl> builtins.add 1 <| builtins.mul 2 <| 3
|
||||
7
|
||||
```
|
||||
|
||||
`<|` and `|>` are right and left associative, respectively, and have lower precedence than any other operator.
|
||||
These properties may change in future releases.
|
||||
|
||||
See [the RFC](https://github.com/NixOS/rfcs/pull/148) for more examples and rationale.
|
||||

- `nix-shell` shebang uses relative path [#4232](https://github.com/NixOS/nix/issues/4232) [#5088](https://github.com/NixOS/nix/pull/5088) [#11058](https://github.com/NixOS/nix/pull/11058)
|
||||
|
||||
<!-- unfortunately no link target for the specific syntax -->
|
||||
Relative [path](@docroot@/language/types.md#type-path) literals in `nix-shell` shebang scripts' options are now resolved relative to the [script's location](@docroot@/glossary.md?highlight=base%20directory#gloss-base-directory).
|
||||
Previously they were resolved relative to the current working directory.
|
||||
|
||||
For example, consider the following script in `~/myproject/say-hi`:
|
||||
|
||||
```shell
|
||||
#!/usr/bin/env nix-shell
|
||||
#!nix-shell --expr 'import ./shell.nix'
|
||||
#!nix-shell --arg toolset './greeting-tools.nix'
|
||||
#!nix-shell -i bash
|
||||
hello
|
||||
```
|
||||
|
||||
Older versions of `nix-shell` would resolve `shell.nix` relative to the current working directory, such as the user's home directory in this example:
|
||||
|
||||
```console
|
||||
[hostname:~]$ ./myproject/say-hi
|
||||
error:
|
||||
… while calling the 'import' builtin
|
||||
at «string»:1:2:
|
||||
1| (import ./shell.nix)
|
||||
| ^
|
||||
|
||||
error: path '/home/user/shell.nix' does not exist
|
||||
```
|
||||
|
||||
Since this release, `nix-shell` resolves `shell.nix` relative to the script's location, and `~/myproject/shell.nix` is used.
|
||||
|
||||
```console
|
||||
$ ./myproject/say-hi
|
||||
Hello, world!
|
||||
```
|
||||
|
||||
**Opt-out**
|
||||
|
||||
This is technically a breaking change, so we have added an option so you can adapt independently of your Nix update.
|
||||
The old behavior can be opted into by setting the option [`nix-shell-shebang-arguments-relative-to-script`](@docroot@/command-ref/conf-file.md#conf-nix-shell-shebang-arguments-relative-to-script) to `false`.
|
||||
This option will be removed in a future release.

- Improve handling of tarballs that don't consist of a single top-level directory [#11195](https://github.com/NixOS/nix/pull/11195)
|
||||
|
||||
In previous Nix releases, the tarball fetcher (used by `builtins.fetchTarball`) erroneously merged top-level directories into a single directory, and silently discarded top-level files that are not directories. This is no longer the case. The new behaviour is that *only* if the tarball consists of a single directory, the top-level path component of the files in the tarball is removed (similar to `tar`'s `--strip-components=1`).

- Setting to warn about large paths [#10778](https://github.com/NixOS/nix/pull/10778)
|
||||
|
||||
Nix can now warn when evaluation of a Nix expression causes a large
|
||||
path to be copied to the Nix store. The threshold for this warning can
|
||||
be configured using the `warn-large-path-threshold` setting,
|
||||
e.g. `--warn-large-path-threshold 100M`.

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/types.md#type-path) enclosed in angle
|
||||
brackets (i.e., `<nixpkgs>`).
|
||||
Add *path* to search path entries used to resolve [lookup paths](@docroot@/language/constructs/lookup-path.md)
|
||||
|
||||
For instance, passing
|
||||
This option may be given multiple times.
|
||||
|
||||
```
|
||||
-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.
|
||||
Paths added through `-I` take precedence over the [`nix-path` configuration setting](@docroot@/command-ref/conf-file.md#conf-nix-path) and the [`NIX_PATH` environment variable](@docroot@/command-ref/env-common.md#env-NIX_PATH).
