synopsis: "Flake lock file generation now ignores local registries"
|
||||
prs: [12019]
|
||||
---
|
||||
|
||||
When resolving indirect flake references like `nixpkgs` in `flake.nix` files, Nix will no longer use the system and user flake registries. It will only use the global flake registry and overrides given on the command line via `--override-flake`.
|
||||
|
||||
This avoids accidents where users have local registry overrides that map `nixpkgs` to a `path:` flake in the local file system, which then end up in committed lock files pushed to other users.
|
||||
|
||||
In the future, we may remove the use of the registry during lock file generation altogether. It's better to explicitly specify the URL of a flake input. For example, instead of
|
||||
```nix
|
||||
{
|
||||
outputs = { self, nixpkgs }: { ... };
|
||||
}
|
||||
```
|
||||
write
|
||||
```nix
|
||||
{
|
||||
inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.11";
|
||||
outputs = { self, nixpkgs }: { ... };

synopsis: "`nix copy` supports `--profile` and `--out-link`"
|
||||
prs: [11657]
|
||||
---
|
||||
|
||||
The `nix copy` command now has flags `--profile` and `--out-link`, similar to `nix build`. `--profile` makes a profile point to the
|
||||
top-level store path, while `--out-link` create symlinks to the top-level store paths.
|
||||
|
||||
For example, when updating the local NixOS system profile from a NixOS system closure on a remote machine, instead of
|
||||
```
|
||||
# nix copy --from ssh://server $path
|
||||
# nix build --profile /nix/var/nix/profiles/system $path
|
||||
```
|
||||
you can now do
|
||||
```
|
||||
# nix copy --from ssh://server --profile /nix/var/nix/profiles/system $path
|
||||
```
|
||||
The advantage is that this avoids a time window where *path* is not a garbage collector root, and so could be deleted by a concurrent `nix store gc` process.

synopsis: "Improved `NIX_SSHOPTS` parsing for better SSH option handling"
|
||||
issues: [5181]
|
||||
prs: [12020]
|
||||
---
|
||||
|
||||
The parsing of the `NIX_SSHOPTS` environment variable has been improved to handle spaces and quotes correctly.
|
||||
Previously, incorrectly split SSH options could cause failures in CLIs like `nix-copy-closure`,
|
||||
especially when using complex ssh invocations such as `-o ProxyCommand="ssh -W %h:%p ..."`.
|
||||
|
||||
This change introduces a `shellSplitString` function to ensure
|
||||
that `NIX_SSHOPTS` is parsed in a manner consistent with shell
|
||||
behavior, addressing common parsing errors.
|
||||
|
||||
For example, the following now works as expected:
|
||||
|
||||
```bash
|
||||
export NIX_SSHOPTS='-o ProxyCommand="ssh -W %h:%p ..."'
|
||||
```
|
||||
|
||||
This update improves the reliability of SSH-related operations using `NIX_SSHOPTS` across Nix CLIs.

Flakes can now refer to other flakes in the same repository using relative paths, e.g.
|

```nix
|

inputs.foo.url = "path:./foo";
|
||||
```
|

|
||||
|
||||
This feature required a change to the lock file format. Previous Nix versions will not be able to use lock files that have locks for relative path inputs in them.

# Release 2.26.0 (2025-01-22)
|

|

- Support for relative path inputs [#10089](https://github.com/NixOS/nix/pull/10089)

This update improves the reliability of SSH-related operations using `NIX_SSHOPTS` across Nix CLIs.
|
||||
|
||||
- Nix is now built using Meson
|
||||
|
||||
As proposed in [RFC 132](https://github.com/NixOS/rfcs/pull/132), Nix's build system now uses Meson/Ninja. The old Make-based build system has been removed.
|
||||
|
||||
- Evaluation caching now works for dirty Git workdirs [#11992](https://github.com/NixOS/nix/pull/11992)
