# Stale bot information
|
||||||
|
|
||||||
|
- Thanks for your contribution!
|
||||||
|
- To remove the stale label, just leave a new comment.
|
||||||
|
- _How to find the right people to ping?_ → [`git blame`](https://git-scm.com/docs/git-blame) to the rescue! (or GitHub's history and blame buttons.)
|
||||||
|
- You can always ask for help on [our Discourse Forum](https://discourse.nixos.org/) or on [Matrix - #nix:nixos.org](https://matrix.to/#/#nix:nixos.org).
|
||||||
|
|
||||||
|
## Suggestions for PRs
|
||||||
|
|
||||||
|
1. GitHub sometimes doesn't notify people who commented / reviewed a PR previously, when you (force) push commits. If you have addressed the reviews you can [officially ask for a review](https://docs.github.com/en/free-pro-team@latest/github/collaborating-with-issues-and-pull-requests/requesting-a-pull-request-review) from those who commented to you or anyone else.
|
||||||
|
2. If it is unfinished but you plan to finish it, please mark it as a draft.
|
||||||
|
3. If you don't expect to work on it any time soon, closing it with a short comment may encourage someone else to pick up your work.
|
||||||
|
4. To get things rolling again, rebase the PR against the target branch and address valid comments.
|
||||||
|
5. If you need a review to move forward, ask in [the Discourse thread for PRs that need help](https://discourse.nixos.org/t/prs-in-distress/3604).
|
||||||
|
6. If all you need is a merge, check the git history to find and [request reviews](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/requesting-a-pull-request-review) from people who usually merge related contributions.
|
||||||
|
|
||||||
|
## Suggestions for issues
|
||||||
|
|
||||||
|
1. If it is resolved (either for you personally, or in general), please consider closing it.
|
||||||
|
2. If this might still be an issue, but you are not interested in promoting its resolution, please consider closing it while encouraging others to take over and reopen an issue if they care enough.
|
||||||
|
3. If you still have interest in resolving it, try to ping somebody who you believe might have an interest in the topic. Consider discussing the problem in [our Discourse Forum](https://discourse.nixos.org/).
|
||||||
|
4. As with all open source projects, your best option is to submit a Pull Request that addresses this issue. We :heart: this attitude!
|
||||||
|
|
||||||
|
**Memorandum on closing issues**
|
||||||
|
|
||||||
|
Don't be afraid to close an issue that holds valuable information. Closed issues stay in the system for people to search, read, cross-reference, or even reopen--nothing is lost! Closing obsolete issues is an important way to help maintainers focus their time and effort.

We now have Clang build profiling available, which generates Chrome
|
||||||
|
tracing files for each compilation unit. To enable it, run `meson configure
|
||||||
|
build -Dprofile-build=enabled` then rerun the compilation.
|
||||||
|
|
||||||
|
If you want to make the build go faster, do a clang build with meson, then run
|
||||||
|
`maintainers/buildtime_report.sh build`, then contemplate how to improve the
|
||||||
|
build time.
|
||||||
|
|
||||||
|
You can also look at individual object files' traces in
|

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!

`builtins.trace` calls will behave similarly to `builtins.break` and will enter

A system for deprecation (and then the planned removal) of undesired language features has been put into place.
|
|
||||||
It is controlled via feature flags much like experimental features, except that the deprecations are enabled default,
|
|
||||||
and can be disabled via the flags for backwards compatibility (opt-out with `--extra-deprecated-features` or the Nix configuration file).
|
|
||||||
|
|
||||||
- `url-literals`: **URL literals** have long been obsolete and discouraged of use, and now they are officially deprecated.
|
|
||||||
This means that all URLs must be properly put within quotes like all other strings.
|
|
||||||
- `rec-set-overrides`: **__overrides** is an old arcane syntax which has not been in use for more than a decade.
|
|
||||||
It is soft-deprecated with a warning only, with the plan to turn that into an error in a future release.
|
|
||||||
- `ancient-let`: **The old `let` syntax** (`let { body = …; … }`) is soft-deprecated with a warning as well. Use the regular `let … in` instead.

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
|
||||||
|
```
|
||||||
|
|
||||||
|
Lix 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, Lix will correctly enter the debugger at both breakpoints.

Reduce the size of the `Env` struct used in the evaluator by a pointer, or 8 bytes on most modern machines.

This reduces memory usage during eval by around 2% and wall time by around 3%.

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 effects scheduling which will cause Lix 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.

Previously nested-input overrides were ignored; that is, the following did not
|
||||||
|
override anything, in spite of the `nix3-flake` manual documenting it working:
|
||||||
|
|
||||||
|
```
|
||||||
|
{
|
||||||
|
inputs = {
|
||||||
|
foo.url = "github:bar/foo";
|
||||||
|
foo.inputs.bar.inputs.nixpkgs = "nixpkgs";
|
||||||
|
};
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
This is useful to avoid the 1000 instances of nixpkgs problem without having
|
||||||
|
each flake in the dependency tree to expose all of its transitive dependencies
|
||||||
|
for modification.

Always print lambda formals in lexicographic order rather than the internal, creation-time based symbol order.
|
||||||
|
This makes printed formals independent of the context they appear in.

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) 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.

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 officially, definitively 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).

Lix now enables build options such as trapping on signed overflow and enabling
|
||||||
|
libstdc++ assertions by default. These may find new bugs in Lix, which will
|
||||||
|
present themselves as Lix processes aborting, potentially without an error
|
||||||
|
message.
|
||||||
|
|
||||||
|
If Lix processes abort on your machine, this is a bug. Please file a bug,
|
||||||
|
ideally with the core dump (or information from it).
|
||||||
|
|
||||||
|
On Linux, run `coredumpctl list`, find the crashed process's PID at
|
||||||
|
the bottom of the list, then run `coredumpctl info THE-PID`. You can then paste
|
||||||
|
the output into a bug report.
|
||||||
|
|
||||||
|
On macOS, open the Console app from Applications/Utilities, select Crash
|
||||||
|
Reports, select the crash report in question. Right click on it, select Open In
|
||||||
|
Finder, then include that file in your bug report. [See the Apple
|
||||||
|
documentation][apple-crashreport] for more details.

`nix show-config` was renamed to `nix config show` to be more consistent with the rest of the command-line interface.
|
||||||
|
|

Running `nix show-config` will now print a deprecation warning saying to use `nix config show` instead.

The interface for creating and updating lock files has been overhauled:
|
||||||
|
|
||||||
|
- [`nix flake lock`](@docroot@/command-ref/new-cli/nix3-flake-lock.md) only creates lock files and adds missing inputs now.
|
||||||
|
It will *never* update existing inputs.
|
||||||
|
|
||||||
|
- [`nix flake update`](@docroot@/command-ref/new-cli/nix3-flake-update.md) does the same, but *will* update inputs.
|
||||||
|
- Passing no arguments will update all inputs of the current flake, just like it already did.
|
||||||
|
- Passing input names as arguments will ensure only those are updated. This replaces the functionality of `nix flake lock --update-input`
|
||||||
|
- To operate on a flake outside the current directory, you must now pass `--flake path/to/flake`.
|
||||||
|
|
||||||
|
- The flake-specific flags `--recreate-lock-file` and `--update-input` have been removed from all commands operating on installables.
|
||||||
|
They are superceded by `nix flake update`.

[`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. Indices have been removed. 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. Lix 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 Lix.

`builtins.nixVersion` now returns a fixed value `"2.18.3-lix"`. This prevents

feature detection assuming that features that exist in Nix post-Lix-branch-off
|
||||||
|
might exist, even though the Lix version is greater than the Nix version.
|

In the future, check for builtins for feature detection. If a feature cannot be

detected by *those* means, please file a Lix bug.

Using `:doc` in the REPL now supports showing documentation comments when defined on a function.
|
||||||
|
|
||||||
|
Previously this was only able to document builtins, however it now will show comments defined on a lambda as well.
|
||||||
|
|
||||||
|
This support is experimental and relies on an embedded version of [nix-doc](https://github.com/lf-/nix-doc).
|
||||||
|
|
||||||
|
The logic also supports limited Markdown formatting of doccomments and should easily support any [RFC 145](https://github.com/NixOS/rfcs/blob/master/rfcs/0145-doc-strings.md)
|
||||||
|
compatible documentation comments in addition to simple commented documentation.

synopsis: reintroduce shortened `-E` form for `--expr` to new CLI

In the old CLI, it was possible to supply a shorter `-E` flag instead of fully
|
||||||
|
specifying `--expr` every time you wished to provide an expression that would
|
||||||
|
be evaluated to produce the given command's input. This was retained for the
|
||||||
|
`--file` flag when the new CLI utilities were written with `-f`, but `-E` was
|
||||||
|
dropped.
|
||||||
|
|
||||||
|
We now restore the `-E` short form for better UX. This is most useful for
|
||||||
|
`nix eval` but most any command that takes an Installable argument should benefit
|
||||||
|
from it as well.

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:
|

|
|
||||||
|
```
|

|

|
||||||

||||||

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).
|

On non-NixOS, Nix is conventionally installed into a `nix-env` style profile at /nix/var/nix/profiles/default.
|
||||||
|
Like any `nix-env` profile, using `nix profile` on it automatically migrates it to a `nix profile` style profile, which is incompatible with `nix-env`.
|
||||||
|
`nix upgrade-nix` previously relied solely on `nix-env` to do the upgrade, but now will work fine with either kind of profile.

`with` expressions using non-attrset values to resolve variables are now reported with proper positions.
|
||||||
|
|
||||||
|
Previously an incorrect `with` expression would report no position at all, making it hard to determine where the error originated:
|
||||||
|
|
||||||
|
```
|
||||||
|
nix-repl> with 1; a
|
||||||
|

|
||||||

|
|
||||||
|
error: value is an integer while a set was expected
|
||||||
|
```
|
||||||
|
|
||||||

Now position information is preserved and reported as with most other errors:
|
||||||
|
|
||||||
|
```
|
||||||

This section describes the notion of *deprecated features*, and how it fits into the big picture of the development of Lix.
|
|
||||||
|
|
||||||
# What are deprecated features?
|
|
||||||
|
|
||||||
Deprecated features are disabled by default, with the intent to eventually remove them.
|
|
||||||
Users must explicitly enable them to keep using them, by toggling the associated [deprecated feature flags](@docroot@/command-ref/conf-file.md#conf-deprecated-features).
|
|
||||||
This allows backwards compatibility and a graceful transition away from undesired features.
|
|
||||||
|
|
||||||
# Which features can be deprecated?
|
|
||||||
|
|
||||||
Undesired features should be soft-deprecated by yielding a warning when used for a significant amount of time before the can be deprecated.
|
|
||||||
Legacy obsolete feature with little to no usage may go through this process faster.
|
|
||||||
Deprecated features should have a migration path to a preferred alternative.
|
|
||||||
|
|
||||||
# Lifecycle of a deprecated feature
|
|
||||||
|
|
||||||
This description is not normative, but a feature removal may roughly happen like this:
|
|
||||||
|
|
||||||
1. Add a warning when the feature is being used.
|
|
||||||
2. Disable the feature by default, putting it behind a deprecated feature flag.
|
|
||||||
- If disabling the feature started out as an opt-in experimental feature, turn that experimental flag into a no-op or remove it entirely.
|
|
||||||
For example, `--extra-experimental-features=no-url-literals` becomes `--extra-deprecated-features=url-literals`.
|
|
||||||
3. Decide on a time frame for how long that feature will still be supported for backwards compatibility, and clearly communicate that in the error messages.
|
|
||||||
- Sometimes, automatic migration to alternatives is possible, and such should be provided if possible
|
|
||||||
- At least one NixOS release cycle should be the minimum
|
|
||||||
4. Finally remove the feature entirely, only keeping the error message for those still using it.
|
|
||||||
|
|
||||||
# Relation to language versioning
|
|
||||||
|
|
||||||
Obviously, removing anything breaks backwards compatibility.
|
|
||||||
In an ideal world, we'd have SemVer controls over the language and its features, cleanly allowing us to make breaking changes.
|
|
||||||
See https://wiki.lix.systems/books/lix-contributors/page/language-versioning and [RFC 137](https://github.com/nixos/rfcs/pull/137) for efforts on that.
|
|
||||||
However, we do not live in such an ideal world, and currently this goal is so far away, that "just disable it with some back-compat for a couple of years" is the most realistic solution, especially for comparatively minor changes.

Lix can also be easily cross compiled to the following arbitrarily-chosen system doubles, which can be useful for bootstrapping Lix on new platforms.

These are specified in `crossSystems` in `flake.nix`; feel free to submit changes to add new ones if they are useful to you.

- `riscv64-linux`
|
|
||||||
|
|
||||||
For example, to cross-compile Lix for `armv6l-linux` from another Linux, use the following:
|
|
||||||
|
|
||||||
```console
|
|
||||||
$ nix build .#nix-armv6l-linux
|
|
||||||
```
|
|
||||||
|
|
||||||
It's also possible to cross-compile a tarball of binaries suitable for the Lix installer, for example, for `riscv64-linux`:
|
|
||||||
|
|
||||||
```console
|
|
||||||
$ nix build .#nix-riscv64-linux.passthru.binaryTarball

|
|
||||||
|
|
||||||
If you are forward-porting a change from CppNix, please credit the original author, and optionally credit yourself.
|
|
||||||
When adding credits metadata for people external to the project and deciding whether to put in a `display_name`, consider what they are generally known as in the community; even if you know their full name (e.g. from their GitHub profile), we suggest only adding it as a display name if that is what they go by in the community.
|
|
||||||
There are multiple reasons we follow this practice, but it boils down to privacy and consent: we would rather not capture full names that are not widely used in the community without the consent of the parties involved, even if they are publicly available.
|
|
||||||
As of this writing, the entries with full names as `display_name` are either members of the CppNix team or people who added them themselves.
|
|
||||||
|
|
||||||
The names specified in `credits` are used as keys to look up the authorship info in `doc/manual/change-authors.yml`.
|
|
||||||
The only mandatory part is that every key appearing in `credits` has an entry present in `change-authors.yml`.
|
|
||||||
All of the following properties are optional; you can specify `{}` as the metadata if you want a simple non-hyperlinked mention.
|

The following properties are supported:
|
|
||||||
|
|
||||||
- `display_name`: display name used in place of the key when showing names, if present.
|
|
||||||
- `forgejo`: Forgejo username. The name in the release notes will be a link to this, if present.
|
|
||||||
- `github`: GitHub username, used if `forgejo` is not set, again making a link.

## Magic environment variables
|
|
||||||
|
|
||||||
FIXME: maybe this section should be moved elsewhere or turned partially into user docs, but I just need a complete index for now.
|
|
||||||
I actually want to ban people calling getenv without writing documentation, and produce a comprehensive list of env-vars used by Lix and enforce it.
|
|
||||||
|
|
||||||
This is a non-exhaustive list of almost all environment variables, magic or not, accepted or used by various parts of the test suite as well as Lix itself.
|
|
||||||
Please add more if you find them.
|
|
||||||
|
|
||||||
I looked for these in the testsuite with the following bad regexes:
|
|
||||||
|
|
||||||
```
|
|
||||||
rg '(?:[^A-Za-z]|^)(_[A-Z][^-\[ }/:");$(]+)' -r '$1' --no-filename --only-matching tests | sort -u > vars.txt
|
|
||||||
rg '\$\{?([A-Z][^-\[ }/:");]+)' -r '$1' --no-filename --only-matching tests | sort -u > vars.txt
|
|
||||||
```
|
|
||||||
|
|
||||||
I grepped `src/` for `get[eE]nv\("` to find the mentions in Lix code.
|
|
||||||
|
|
||||||
### Used by Lix testing support code
|
|
||||||
|
|
||||||
- `_NIX_TEST_ACCEPT` (optional) - Writes out the result of a characterization test as the new expected value.
|
|
||||||
**Expected value**: 1
|
|
||||||
|
|
||||||
- `_NIX_TEST_UNIT_DATA` - The path to the directory for the data for a given unit test suite.
|
|
||||||
|
|
||||||
**Expected value**: `tests/unit/libstore/data/libstore` or similar
|
|
||||||
|
|
||||||
|
|
||||||
### Used by Lix
|
|
||||||
|
|
||||||
- `_NIX_FORCE_HTTP` - Forces file URIs to be treated as remote ones.
|
|
||||||
|
|
||||||
Used by `src/libfetchers/git.cc`, `src/libstore/http-binary-cache-store.cc`,
|
|
||||||
`src/libstore/local-binary-cache-store.cc`. Seems to be for forcing Git
|
|
||||||
clones of `git+file://` URLs, making the HTTP binary
|
|
||||||
cache store accept `file://` URLs (presumably passing them to curl?), and
|
|
||||||
unknown reasons for the local binary cache.
|
|
||||||
|
|
||||||
FIXME(jade): is this obscuring a bug in https://git.lix.systems/lix-project/lix/issues/200?
|
|
||||||
|
|
||||||
**Expected value**: 1
|
|
||||||
- `NIX_ATTRS_SH_FILE`, `NIX_ATTRS_JSON_FILE` (output) - Set by Lix builders; see
|
|
||||||
`structuredAttrs` documentation.
|
|
||||||
- `NIX_BIN_DIR`, `NIX_STORE_DIR` (or its inconsistently-used old alias `NIX_STORE`), `NIX_DATA_DIR`,
|
|
||||||
`NIX_LOG_DIR`, `NIX_LOG_DIR`, `NIX_STATE_DIR`, `NIX_CONF_DIR` -
|
|
||||||
Overrides compile-time configuration of various locations used by Lix. See `src/libstore/globals.cc`.
|
|
||||||
|
|
||||||
**Expected value**: a directory
|
|
||||||
- `NIX_DAEMON_SOCKET_PATH` (optional) - Overrides the daemon socket path from `$NIX_STATE_DIR/daemon-socket/socket`.
|
|
||||||
|
|
||||||
**Expected value**: path to a socket
|
|
||||||
- `NIX_LOG_FD` (output) - An FD number for logs in `internal-json` format to be sent to.
|
|
||||||
Used for, mostly, "setPhase" in nixpkgs setup.sh, but can also be creatively used to print verbose log messages from derivations.
|
|
||||||
|
|
||||||
**Provided value**: number corresponding to an FD in the builder
|
|
||||||
- `NIX_PATH` - Search path for `<whatever>`. Documented elsewhere in the manual.
|
|
||||||
|
|
||||||
**Expected value**: `:` separated list of things that are not necessarily pointing to filesystem paths
|
|
||||||
- `NIX_REMOTE` - The default value of the Lix setting `store`.
|
|
||||||
|
|
||||||
**Expected value**: "daemon", usually. Could be "auto" or any other value acceptable in `store`.
|
|
||||||
- `NIX_BUILD_SHELL` - Documented elsewhere; the shell to invoke with `nix-shell` but not `nix develop`/`nix shell`.
|
|
||||||
The latter ignoring it altogether seems like a bug.
|
|
||||||
|
|
||||||
**Expected value**: the path to an executable shell
|
|
||||||
- `PRINT_PATH` - Undocumented. Used by `nix-prefetch-url` as an alternative form of `--print-path`. Why???
|
|
||||||
- `_NIX_IN_TEST` - If present with any value, makes `fetchClosure` accept file URLs in addition to HTTP ones. Why is this not `_NIX_FORCE_HTTP`??
|
|
||||||
|
|
||||||
Not used anywhere else.
|
|
||||||
- `NIX_ALLOW_EVAL` - Used by eval-cache tests to block evaluation if set to `0`.
|
|
||||||
|
|
||||||
**Expected value**: 1 or 0
|
|
||||||
- `EDITOR` - Used by `editorFor()`, which has some extremely sketchy editor-detection code for jumping to line numbers.
|
|
||||||
- `LISTEN_FDS` and `LISTEN_PID` - Used for systemd socket activation using the systemd socket activation protocol.
|
|
||||||
- `NIX_PAGER` (alternatively, `PAGER`) - Used to select a pager for Lix output. Why does this not use libutil `getEnv()`?
|
|
||||||
- `LESS` (output) - Sets the pager settings for `less` when invoked by Lix.
|
|
||||||
- `NIX_IGNORE_SYMLINK_STORE` - When set, Lix allows the store to be a symlink. Why do we support this?
|
|
||||||
|
|
||||||
Apparently [someone was using it enough to fix it](https://github.com/NixOS/nix/pull/4038).
|
|
||||||
- `NIX_SSL_CERT_FILE` (alternatively, `SSL_CERT_FILE`) - Used to set CA certificates for libcurl.
|
|
||||||
|
|
||||||
**Expected value**: "/etc/ssl/certs/ca-certificates.crt" or similar
|
|
||||||
- `NIX_REMOTE_SYSTEMS` - Used to set `builders`. Can we please deprecate this?
|
|
||||||
- `NIX_USER_CONF_FILES` - `:` separated list of config files to load before
|
|
||||||
`/nix/nix.conf` under each of `XDG_CONFIG_DIRS`.
|
|
||||||
- `NIX_CONFIG` - Newline separated configuration to load into Lix.
|
|
||||||
- `NIX_GET_COMPLETIONS` - Returns completions.
|
|
||||||
Unsure of the exact format, someone should document it; either way my shell never had any completions.
|
|
||||||
|
|
||||||
**Expected value**: number of completions to return.
|
|
||||||
- `IN_SYSTEMD` - Used to switch the logging format so that systemd gets the correct log levels. I think.
|
|
||||||
- `NIX_HELD_LOCKS` - Not used, what is this for?? We should surely remove it right after searching github?
|
|
||||||
- `GC_INITIAL_HEAP_SIZE` - Used to set the initial heap size, processed by boehmgc.
|
|
||||||
- `NIX_COUNT_CALLS` - Documented elsewhere; prints call counts for profiling purposes.
|
|
||||||
- `NIX_SHOW_STATS` - Documented elsewhere; prints various evaluation statistics like function calls, gc info, and similar.
|
|
||||||
- `NIX_SHOW_STATS_PATH` - Writes those statistics into a file at the given path instead of stdout. Undocumented.
|
|
||||||
- `NIX_SHOW_SYMBOLS` - Dumps the symbol table into the show-stats json output.
|
|
||||||
- `TERM` - If `dumb` or unset, disables ANSI colour output.
|
|
||||||
- `FORCE_COLOR`, `CLICOLOR_FORCE` - Enables ANSI colour output if `NO_COLOR`/`NOCOLOR` not set.
|
|
||||||
- `NO_COLOR`, `NOCOLOR` - Disables ANSI colour output.
|
|
||||||
- `_NIX_DEVELOPER_SHOW_UNKNOWN_LOCATIONS` - Highlights unknown locations in errors.
|
|
||||||
- `NIX_PROFILE` - Selects which profile `nix-env` will operate on. Documented elsewhere.
|
|
||||||
- `NIX_SSHOPTS` - Options passed to `ssh(1)` when using a ssh remote store.
|
|
||||||
Incorrectly documented on `nix-copy-closure` which is *surely* not the only place they are used??
|
|
||||||
- `_NIX_TEST_GC_SYNC_1` - Path to a pipe that is used to block the GC briefly to validate invariants from the test suite.
|
|
||||||
- `_NIX_TEST_GC_SYNC_2` - Path to a pipe that is used to block the GC briefly to validate invariants from the test suite.
|
|
||||||
- `_NIX_TEST_FREE_SPACE_FILE` - Path to a file containing a decimal number with the free space that the GC is to believe it has.
|
|
||||||
- Various XDG vars
|
|
||||||
- `NIX_DEBUG_SQLITE_TRACES` - Dump all sqlite queries to the log at `notice` level.
|
|
||||||
- `_NIX_TEST_NO_SANDBOX` - Disables actually setting up the sandbox on macOS while leaving other logic the same. Unused on other platforms.
|
|
||||||
- `_NIX_TRACE_BUILT_OUTPUTS` - Dumps all the derivation paths alongside their outputs as lines into a file of the given name.
|
|
||||||
|
|
||||||
### Used by the functional test framework
|
|
||||||
|
|
||||||
- `NIX_DAEMON_PACKAGE` - Runs the test suite against an alternate Nix daemon with the current client.
|
|
||||||
|
|
||||||
**Expected value**: something like `/nix/store/...-nix-2.18.2`
|
|
||||||
- `NIX_CLIENT_PACKAGE` - Runs the test suite against an alternate Nix client with the current daemon.
|
|
||||||
|
|
||||||
**Expected value**: something like `/nix/store/...-nix-2.18.2`
|
|
||||||
- `NIX_TESTS_CA_BY_DEFAULT` - Pass `__contentAddressed`, `outputHashMode` and `outputHashAlgo` to builds of some input-addressed derivations in the test suite.
|
|
||||||
|
|
||||||
**Expected value**: 1
|
|
||||||
- `TEST_DATA` - Not an environment variable! This is used in repl characterization tests to refer to `tests/functional/repl_characterization/data`.
|

## Setting up the build users
|

The Lix team considers the goal of the sandbox to be primarily for preventing reproducibility mistakes, and does not consider multi-user mode to be a strong security boundary between users.
|
|
||||||
|
|
||||||
Do not evaluate or build untrusted, potentially-malicious, Nix language code on machines that you care deeply about maintaining user isolation on.
|
|
||||||
|
|
||||||
Although we would consider any sandbox escapes to be serious security bugs and we intend to fix them, we are not confident enough in the daemon's security to call the daemon a security boundary.

[multi-user-should-not-be-root]: https://git.lix.systems/lix-project/lix/issues/18
|
|
||||||
|
|
||||||
## Trust model
|
|
||||||
|
|
||||||
There are two categories of users of the Lix daemon: trusted users and untrusted users.
|
|
||||||
The Lix daemon only allows connections from users that are either trusted users, or are specified in, or are members of groups specified in, [`allowed-users`](../command-ref/conf-file.md#conf-allowed-users) in `nix.conf`.
|
|
||||||
Trusted users are users and users of groups specified in [`trusted-users`](../command-ref/conf-file.md#conf-trusted-users) in `nix.conf`.
|
|
||||||
|
|
||||||
All users of the Lix daemon may do the following to bring things into the Nix store:
|
|
||||||
|
|
||||||
- Users may load derivations and output-addressed files into the store with `nix-store --add` or through Nix language code.
|
|
||||||
- Users may locally build derivations, either of the output-addressed or input-addressed variety, creating output paths.
|
|
||||||
|
|
||||||
Note that [fixed-output derivations only consider name and hash](https://github.com/NixOS/nix/issues/969), so it is possible to write a fixed-output derivation for something important with a bogus hash and have it resolve to something else already built in the store.
|
|
||||||
|
|
||||||
On systems with `sandbox` enabled (default on Linux; [not *yet* on macOS][sandbox-enable-macos]), derivations are either:
|
|
||||||
- Input-addressed, so they are run in the sandbox with no network access, with the following exceptions:
|
|
||||||
|
|
||||||
- The (poorly named, since it is not *just* about chroot) property `__noChroot` is set on the derivation and `sandbox` is set to `relaxed`.
|
|
||||||
- On macOS, the derivation property `__darwinAllowLocalNetworking` allows network access to localhost from input-addressed derivations regardless of the `sandbox` setting value. This property exists with such semantics because macOS has no network namespace equivalent to isolate individual processes' localhost networking.
|
|
||||||
- Output-addressed, so they are run with network access but their result must match an expected hash.
|
|
||||||
|
|
||||||
Trusted users may set any setting, including `sandbox = false`, so the sandbox state can be different at runtime from what is described in `nix.conf` for builds invoked with such settings.
|
|
||||||
- Users may copy appropriately-signed derivation outputs into the store.
|
|
||||||
|
|
||||||
By default, any paths *copied into a store* (such as by substitution) must have signatures from [`trusted-public-keys`](../command-ref/conf-file.md#conf-trusted-public-keys) unless they are [output-addressed](../glossary.md#gloss-output-addressed-store-object).
|
|
||||||
|
|
||||||
Unsigned paths may be copied into a store if [`require-sigs`](../command-ref/conf-file.md#conf-require-sigs) is disabled in the daemon's configuration (not default), or if the client is a trusted user and passed `--no-check-sigs` to `nix copy`.
|
|
||||||
- Users may request that the daemon substitutes appropriately-signed derivation outputs from a binary cache in the daemon's [`substituters`](../command-ref/conf-file.md#conf-substituters) list.
|
|
||||||
|
|
||||||
Untrusted clients may also specify additional values for `substituters` (via e.g. `--extra-substituters` on a Nix command) that are listed in [`trusted-substituters`](../command-ref/conf-file.md#conf-trusted-substituters).
|
|
||||||
|
|
||||||
A client could in principle substitute such paths itself then copy them to the daemon (see clause above) if they are appropriately signed but are *not* from a trusted substituter, however this is not implemented in the current Lix client to our knowledge, at the time of writing.
|
|
||||||
This probably means that `trusted-substituters` is a redundant setting except insofar as such substitution would have to be done on the client rather than as root on the daemon; and it is highly defensible to not allow random usage of our HTTP client running as root.

### The Lix daemon as a security non-boundary
|
|
||||||
|
|
||||||
The Lix team and wider community does not consider the Lix daemon to be a *security boundary* against malicious Nix language code.
|
|
||||||
|
|
||||||
Although we do our best to make it secure, we do not recommend sharing a Lix daemon with potentially malicious users.
|
|
||||||
That means that public continuous integration (CI) builds of untrusted Nix code should not share builders with CI that writes into a cache used by trusted infrastructure.
|
|
||||||
|
|
||||||
For example, [hydra.nixos.org], which is the builder for [cache.nixos.org], does not execute untrusted Nix language code; a separate system, [ofborg] is used for CI of nixpkgs pull requests.
|
|
||||||
The build output of pull request CI is never pushed to [cache.nixos.org], and those systems are considered entirely untrusted.
|
|
||||||
|
|
||||||
This is because, among other things, the Lix sandbox is *more* susceptible to kernel exploits than Docker, which, unlike Lix, blocks nested user namespaces via `seccomp` in its default policy, and there have been many kernel bugs only exposed to unprivileged users via user namespaces allowing otherwise-root-only system calls.
|
|
||||||
In general, the Lix sandbox is set up to be relatively unrestricted while maintaining its goals of building useful, reproducible software; security is not its primary goal.
|
|
||||||
|
|
||||||
The Lix sandbox is a custom *non-rootless* Linux container implementation that has not been audited to nearly the same degree as Docker and similar systems.
|
|
||||||
Also, the Lix daemon is a complex and historied C++ executable running as root with very little privilege separation.
|
|
||||||
All of this means that a security hole in the Lix daemon gives immediate root access.
|
|
||||||
Systems like Docker (especially non-rootless Docker) should *themselves* probably not be used in a multi-tenant manner with mutually distrusting tenants, but the Lix daemon *especially* should not be used as such as of this writing.
|
|
||||||
|
|
||||||
The primary purpose of the sandbox is to strongly encourage packages to be reproducible, a goal which it is generally quite successful at.

### Trusted users
|
|
||||||
|
|
||||||
Trusted users are permitted to set any setting and bypass security restrictions on the daemon.
|
|
||||||
They are currently in widespread use for a couple of reasons such as remote builds (which we [intend to fix](https://git.lix.systems/lix-project/lix/issues/171)).
|
|
||||||
|
|
||||||
Trusted users are effectively root on Nix daemons running as root (the default configuration) for *at least* the following reasons, and should be thus thought of as equivalent to passwordless sudo.
|
|
||||||
This is not a comprehensive list.
|
|
||||||
|
|
||||||
- They may copy an unsigned malicious built output into the store for `systemd` or anything else that will run as root, then when the system is upgraded, that path will be used from the local store rather than substituted.
|
|
||||||
- They may set the following settings that are commands the daemon will run as root:
|
|
||||||
- `build-hook`
|
|
||||||
- `diff-hook`
|
|
||||||
- `pre-build-hook`
|
|
||||||
- `post-build-hook`
|
|
||||||
- They may set `build-users-group`.
|
|
||||||
|
|
||||||
In particular, they may set it to empty string, which runs builds as root with respect to the rest of the system (!!).
|
|
||||||
We, too, [think that is absurd and intend to not accept such a configuration](https://git.lix.systems/lix-project/lix/issues/242).
|
|
||||||
It is then simply an exercise to the reader to find a daemon that does `SCM_CREDENTIALS` over a `unix(7)` socket and lets you run commands as root, and mount it into the sandbox with `extra-sandbox-paths`.
|
|
||||||
|
|
||||||
At the very least, the Lix daemon itself (since `root` is a trusted user by default) and probably `systemd` qualify for this.
|
|
||||||
- They may set the `builders` list, which will have ssh run as root.
|
|
||||||
We aren't sure if there is a way to abuse this for command execution but it's plausible.
|
|
||||||
|
|
||||||
Note that setting `accept-flake-config` allows arbitrary Nix flakes to set Nix settings in the `nixConfig` stanza.
|
|
||||||
Do not set this setting or pass `--accept-flake-config` while executing untrusted Nix language code as a trusted user for the reasons above!
|
|
||||||
|
|
||||||
## Build users

|
||||||

|
They should all be members of the *build users group* `nixbld`. This

|
as follows:
|
||||||
|
|
||||||
[auto-allocate-uids-issue]: https://git.lix.systems/lix-project/lix/issues/387
|
|
||||||
|
|
||||||
If, for some reason, you need to create such users manually, the following command will create 10 build users on Linux:
|
|
||||||
|
|
||||||
```console
|
```console
|
||||||
$ groupadd -r nixbld
|
$ groupadd -r nixbld

@ -124,12 +35,43 @@ $ for n in $(seq 1 10); do useradd -c "Nix build user $n" \

nixbld$n; done
|
nixbld$n; done

||||||
```
|
```
|
||||||
|
|
||||||
|
This creates 10 build users. There can never be more concurrent builds
|
||||||
|
than the number of build users, so you may want to increase this if you
|
||||||
|
expect to do many builds at the same time.

|
The [Nix daemon](../command-ref/nix-daemon.md) should be started as

||||||

follows (as `root`):

|
|

```console
|
```console
|
||||||
# nix-daemon
|
$ nix-daemon
|
||||||
```
|
```
|
||||||
|
|
||||||
In standard installations of Lix, the daemon is started by a `systemd` unit (Linux) or `launchd` service (macOS).
|
You’ll want to put that line somewhere in your system’s boot scripts.
|
||||||
|
|
||||||
|
To let unprivileged users use the daemon, they should set the
|
||||||
|
[`NIX_REMOTE` environment variable](../command-ref/env-common.md) to
|
||||||
|
`daemon`. So you should put a line like
|
||||||
|
|
||||||
|
```console
|
||||||
|
export NIX_REMOTE=daemon
|
||||||
|
```
|
||||||
|
|
||||||
|
into the users’ login scripts.
|
||||||
|
|
||||||
|
## Restricting access
|
||||||
|
|
||||||
|
To limit which users can perform Nix operations, you can use the
|
||||||
|
permissions on the directory `/nix/var/nix/daemon-socket`. For instance,
|
||||||
|
if you want to restrict the use of Nix to the members of a group called
|
||||||
|
`nix-users`, do
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ chgrp nix-users /nix/var/nix/daemon-socket
|
||||||
|
$ chmod ug=rwx,o= /nix/var/nix/daemon-socket
|
||||||
|
```
|
||||||
|
|
||||||
|
This way, users who are not in the `nix-users` group cannot connect to
|
||||||
|
the Unix domain socket `/nix/var/nix/daemon-socket/socket`, so they
|
||||||
|
cannot perform Nix operations.

A quasi-constant which will be replaced with an attribute set describing
|
|
||||||
the location where `__curPos` was used, with attributes `file`, `line`,
|
|
||||||
and `column`. For example, `import ./file.nix` will result in
|
|
||||||
|
|
||||||
```nix
|
|
||||||
{
|
|
||||||
column = 1;
|
|
||||||
file = "/path/to/some/file.nix";
|
|
||||||
line = 1;
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
assuming `file.nix` contains nothing but `__curPos`.
|
|
||||||
|
|
||||||
In context without a source file (such as `nix-repl`), it will always
|
|
||||||
be replaced with `null`:
|
|
||||||
|
|
||||||
```nix-repl
|
|
||||||
nix-repl> __curPos
|
|
||||||
null
|
|
||||||
```
|
|
||||||
|
|
||||||
While it may vaguely look like a builtin, this is a very different beast
|
|
||||||
that is handled directly by the parser. It thus cannot be shadowed,
|
|
||||||
bound to a different name, and is also not available under
|
|
||||||
[`builtins`](@docroot@/language/builtin-constants.md#builtins-builtins).
|
|
||||||
|
|
||||||
```nix-repl
|
|
||||||
nix-repl> let __curPos = "no"; in __curPos
|
|
||||||
null
|
|
||||||
```
|
|
||||||
|
|
||||||
Despite this `__curPos`, much like `or`, may still be used as an identifier,
|
|
||||||
it is only treated specially when it appears as an unqualified name:
|
|
||||||
|
|
||||||
```nix-repl
|
|
||||||
nix-repl> { __curPos = 1; }.__curPos
|
|
||||||
1

`or` is used in [Attribute selection](@docroot@/language/operators.html#attribute-selection),
|
|
||||||
where it is a keyword.
|
|
||||||
|
|
||||||
However, it is not a keyword in some other contexts, and can be used as
|
|
||||||
a binding name in attribute sets, let-bindings, non-initial function
|
|
||||||
application position, and as a label in attribute paths.
|
|
||||||
|
|
||||||
Its use as anything other than a keyword is discouraged.
