This builtin allows taking a `drvPath`-like string and turning it into a string
|
||||
with context such that, when it lands in a derivation, it will create
|
||||
dependencies on *all the outputs* in its closure (!). Although `drvPath` does this
|
||||
today, this builtin starts forming a path to migrate to making `drvPath` have a
|
||||
more normal and less surprising string context behaviour (see linked issue and

PR for more details).

Since Lix fixed-output derivations run in the host network namespace (which we
|
||||
wish to change in the future, see
|
||||
[lix#285](https://git.lix.systems/lix-project/lix/issues/285)), they may open
|
||||
abstract-namespace Unix sockets to each other and to programs on the host. Lix
|
||||
contained a now-fixed time-of-check/time-of-use vulnerability where one
|
||||
derivation could send writable handles to files in their final location in the
|
||||
store to another over an abstract-namespace Unix socket, exit, then the other
|
||||
derivation could wait for Lix to hash the paths and overwrite them.
|
||||
|
||||
The impact of this vulnerability is that two malicious fixed-output derivations
|
||||
could create a poisoned path for the sources to Bash or similarly important
|
||||
software containing a backdoor, leading to local privilege execution.

The online flake registry [https://channels.nixos.org/flake-registry.json](https://channels.nixos.org/flake-registry.json) is not pinned in any way,

and the targets of the indirections can both update or change entirely at any

point. Furthermore, it is refetched on every use of a flake reference, even if

there is a local flake reference, and even if you are offline (which breaks).

For now, we deprecate the (any) online flake registry, and vendor a copy of the

current online flake registry. This makes it work offline, and ensures that

it won't change in the future.

it is just the soft limit, this was kind of annoying to do. By passing

Previously, the garbage collector found runtime roots on Darwin by shelling out to `lsof -n -w -F n` then parsing the result. The version of `lsof` packaged in Nixpkgs is very slow on Darwin, so Lix now uses `libproc` directly to speed up GC root discovery, in some tests taking 250ms now instead of 40s.

In order to improve consistency of the build environment, system call filtering and no-new-privileges are now unconditionally enabled on Linux.
|

The `filter-syscalls` and `allow-new-privileges` options which could be used to disable these features under some circumstances have been removed.
|
||||
|
||||
In order to support building on architectures without libseccomp support, the option to disable syscall filtering at build time remains.

However, other uses of this option are heavily discouraged, since it would reduce the security of the sandbox substantially.

The Lix C++ API libraries have had the following changes:
|
||||
- Includes moved from `include/nix/` to `include/lix/`
|
||||
- `pkg-config` files renamed from `nix-expr` to `lix-expr` and so on.
|
||||
- Libraries renamed from `libnixexpr.so` to `liblixexpr.so` and so on.
|
||||
|
||||
There are other changes between Nix 2.18 and Lix, since these APIs are not
|
||||
stable. However, this change in particular is a deliberate compatibility break
|
||||
to force downstreams linking to Lix to specifically handle Lix and avoid Lix
|
||||
accidentally getting ensnared in compatibility code for newer CppNix.
|
||||
|
||||
Migration path:
|
||||
|
||||
- expr.hh -> lix/libexpr/expr.hh
|
||||
- nix/config.h -> lix/config.h
|
||||
|
||||
To apply this migration automatically, remove all `<nix/>` from includes, so `#include <nix/expr.hh>` -> `#include <expr.hh>`.
|
||||
Then, the correct paths will be resolved from the tangled mess, and the clang-tidy automated fix will work.
|
||||
|
||||
Then run the following for out of tree projects (header filter is set to only fix instances in headers in `../src` relative to the compiler's working directory, as would be the case in nix-eval-jobs or other things built with meson, e.g.):
|
||||
|
||||
```console
|
||||
lix_root=$HOME/lix

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.

# SYNOPSIS
|
||||
#
|
||||
# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check for baseline language coverage in the compiler for the specified
|
||||
# version of the C++ standard. If necessary, add switches to CXX and
|
||||
# CXXCPP to enable support. VERSION may be '11' (for the C++11 standard)
|
||||
# or '14' (for the C++14 standard).
|
||||
#
|
||||
# The second argument, if specified, indicates whether you insist on an
|
||||
# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
|
||||
# -std=c++11). If neither is specified, you get whatever works, with
|
||||
# preference for an extended mode.
|
||||
#
|
||||
# The third argument, if specified 'mandatory' or if left unspecified,
|
||||
# indicates that baseline support for the specified C++ standard is
|
||||
# required and that the macro should error out if no mode with that
|
||||
# support is found. If specified 'optional', then configuration proceeds
|
||||
# regardless, after defining HAVE_CXX${VERSION} if and only if a
|
||||
# supporting mode is found.

# AX_CXX_COMPILE_STDCXX_17([ext|noext], [mandatory|optional])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check for baseline language coverage in the compiler for the C++17
|
||||
# standard; if necessary, add switches to CXX and CXXCPP to enable
|
||||
# support.
|
||||
#
|
||||
# This macro is a convenience alias for calling the AX_CXX_COMPILE_STDCXX
|
||||
# macro with the version set to C++17. The two optional arguments are
|
||||
# forwarded literally as the second and third argument respectively.
|
||||
# Please see the documentation for the AX_CXX_COMPILE_STDCXX macro for
|
||||
# more information. If you want to use this macro, you also need to
|
||||
# download the ax_cxx_compile_stdcxx.m4 file.

# Nix maintainers team
|
||||
|
||||
## Motivation
|
||||
|
||||
The team's main responsibility is to set a direction for the development of Nix and ensure that the code is in good shape.
|
||||
|
||||
We aim to achieve this by improving the contributor experience and attracting more maintainers – that is, by helping other people contributing to Nix and eventually taking responsibility – in order to scale the development process to match users' needs.
|
||||
|
||||
### Objectives
|
||||
|
||||
- It is obvious what is worthwhile to work on.
|
||||
- It is easy to find the right place in the code to make a change.
|
||||
- It is clear what is expected of a pull request.
|
||||
- It is predictable how to get a change merged and released.
|
||||
|
||||
### Tasks
|
||||
|
||||
- Establish, communicate, and maintain a technical roadmap
|
||||
- Improve documentation targeted at contributors
|
||||
- Record architecture and design decisions
|
||||
- Elaborate contribution guides and abide to them
|
||||
- Define and assert quality criteria for contributions
|
||||
- Maintain the issue tracker and triage pull requests
|
||||
- Help contributors succeed with pull requests that address roadmap milestones
|
||||
- Manage the release lifecycle
|
||||
- Regularly publish reports on work done
|
||||
- Engage with third parties in the interest of the project
|
||||
- Ensure the required maintainer capacity for all of the above
|
||||
|
||||

|
||||
|
||||
## Meeting protocol
|
||||
|
||||
The team meets twice a week:
|
||||
|
||||
- Discussion meeting: [Fridays 13:00-14:00 CET](https://calendar.google.com/calendar/event?eid=MHNtOGVuNWtrZXNpZHR2bW1sM3QyN2ZjaGNfMjAyMjExMjVUMTIwMDAwWiBiOW81MmZvYnFqYWs4b3E4bGZraGczdDBxZ0Bn)
|
||||
|
||||
1. Triage issues and pull requests from the [No Status](#no-status) column (30 min)
|
||||
2. Discuss issues and pull requests from the [To discuss](#to-discuss) column (30 min)
|
||||
|
||||
- Work meeting: [Mondays 13:00-15:00 CET](https://calendar.google.com/calendar/event?eid=NTM1MG1wNGJnOGpmOTZhYms3bTB1bnY5cWxfMjAyMjExMjFUMTIwMDAwWiBiOW81MmZvYnFqYWs4b3E4bGZraGczdDBxZ0Bn)
|
||||
|
||||
1. Code review on pull requests from [In review](#in-review).
|
||||
2. Other chores and tasks.
|
||||
|
||||
Meeting notes are collected on a [collaborative scratchpad](https://pad.lassul.us/Cv7FpYx-Ri-4VjUykQOLAw), and published on Discourse under the [Nix category](https://discourse.nixos.org/c/dev/nix/50).
|
||||
|
||||
## Project board protocol
|
||||
|
||||
The team uses a [GitHub project board](https://github.com/orgs/NixOS/projects/19/views/1) for tracking its work.
|
||||
|
||||
Items on the board progress through the following states:
|
||||
|
||||
### No Status
|
||||
|
||||
During the discussion meeting, the team triages new items.
|
||||
To be considered, issues and pull requests must have a high-level description to provide the whole team with the necessary context at a glance.
|
||||
|
||||
On every meeting, at least one item from each of the following categories is inspected:
|
||||
|
||||
1. [critical](https://github.com/NixOS/nix/labels/critical)
|
||||
2. [security](https://github.com/NixOS/nix/labels/security)
|
||||
3. [regression](https://github.com/NixOS/nix/labels/regression)
|
||||
4. [bug](https://github.com/NixOS/nix/issues?q=is%3Aopen+label%3Abug+sort%3Areactions-%2B1-desc)
|
||||
5. [tests of existing functionality](https://github.com/NixOS/nix/issues?q=is%3Aopen+label%3Atests+-label%3Afeature+sort%3Areactions-%2B1-desc)
|
||||
|
||||
- [oldest pull requests](https://github.com/NixOS/nix/pulls?q=is%3Apr+is%3Aopen+sort%3Acreated-asc)
|
||||
- [most popular pull requests](https://github.com/NixOS/nix/pulls?q=is%3Apr+is%3Aopen+sort%3Areactions-%2B1-desc)
|
||||
- [oldest issues](https://github.com/NixOS/nix/issues?q=is%3Aissue+is%3Aopen+sort%3Acreated-asc)
|
||||
- [most popular issues](https://github.com/NixOS/nix/issues?q=is%3Aissue+is%3Aopen+sort%3Areactions-%2B1-desc)
|
||||
|
||||
Team members can also add pull requests or issues they would like the whole team to consider.
|
||||
To ensure process quality and reliability, all non-trivial pull requests must be triaged before merging.
|
||||
|
||||
If there is disagreement on the general idea behind an issue or pull request, it is moved to [To discuss](#to-discuss).
|
||||
Otherwise, the issue or pull request in questions get the label [`idea approved`](https://github.com/NixOS/nix/labels/idea%20approved).
|
||||
For issues this means that an implementation is welcome and will be prioritised for review.
|
||||
For pull requests this means that:
|
||||
- Unfinished work is encouraged to be continued.
|
||||
- A reviewer is assigned to take responsibility for getting the pull request merged.
|
||||
The item is moved to the [Assigned](#assigned) column.
|
||||
- If needed, the team can decide to do a collarorative review.
|
||||
Then the item is moved to the [In review](#in-review) column, and review session is scheduled.
|
||||
|
||||
What constitutes a trivial pull request is up to maintainers' judgement.
|
||||
|
||||
### To discuss
|
||||
|
||||
Pull requests and issues that are deemed important and controversial are discussed by the team during discussion meetings.
|
||||
|
||||
This may be where the merit of the change itself or the implementation strategy is contested by a team member.
|
||||
|
||||
As a general guideline, the order of items is determined as follows:
|
||||
|
||||
- Prioritise pull requests over issues
|
||||
|
||||
Contributors who took the time to implement concrete change proposals should not wait indefinitely.
|
||||
|
||||
- Prioritise fixing bugs and testing over documentation, improvements or new features
|
||||
|
||||
The team values stability and accessibility higher than raw functionality.
|
||||
|
||||
- Interleave issues and PRs
|
||||
|
||||
This way issues without attempts at a solution get a chance to get addressed.
|
||||
|
||||
### In review
|
||||
|
||||
Pull requests in this column are reviewed together during work meetings.
|
||||
This is both for spreading implementation knowledge and for establishing common values in code reviews.
|
||||
|
||||
When the overall direction is agreed upon, even when further changes are required, the pull request is assigned to one team member.
|
||||
If significant changes are requested or reviewers cannot come to a conclusion in reasonable time, the pull request is [marked as draft](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/changing-the-stage-of-a-pull-request#converting-a-pull-request-to-a-draft).
|
||||
|
||||
### Assigned
|
||||
|
||||
One team member is assigned to each of these pull requests.
|
||||
They will communicate with the authors, and make the final approval once all remaining issues are addressed.
|
||||
|
||||
If more substantive issues arise, the assignee can move the pull request back to [To discuss](#to-discuss) or [In review](#in-review) to involve the team again.
|
||||
|
||||
### Flowchart
|
||||
|
||||
The process is illustrated in the following diagram:

# Backporting
|
||||
|
||||
To [automatically backport a pull request](https://github.com/NixOS/nix/blob/master/.github/workflows/backport.yml) to a release branch once it's merged, assign it a label of the form [`backport <branch>`](https://github.com/NixOS/nix/labels?q=backport).
|
||||
|
||||
Since [GitHub Actions workflows will not trigger other workflows](https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow), checks on the automatic backport need to be triggered by another actor.
|
||||
This is achieved by closing and reopening the backport pull request.
|
||||
|
||||
This specifically affects the [`installer_test`] check.
|
||||
Note that it only runs after the other tests, so it may take a while to appear.
|
||||
|
||||
[`installer_test`]: https://github.com/NixOS/nix/blob/895dfc656a21f6252ddf48df0d1f215effa04ecb/.github/workflows/ci.yml#L70-L91

# Nix release process
|
||||
|
||||
## Release artifacts
|
||||
|
||||
The release process is intended to create the following for each
|
||||
release:
|
||||
|
||||
* A Git tag
|
||||
|
||||
* Binary tarballs in https://releases.nixos.org/?prefix=nix/
|
||||
|
||||
* Docker images
|
||||
|
||||
* Closures in https://cache.nixos.org
|
||||
|
||||
* (Optionally) Updated `fallback-paths.nix` in Nixpkgs
|
||||
|
||||
* An updated manual on https://nixos.org/manual/nix/stable/
|
||||
|
||||
## Creating a new release from the `master` branch
|
||||
|
||||
* Make sure that the [Hydra `master` jobset](https://hydra.nixos.org/jobset/nix/master) succeeds.
|
||||
|
||||
* In a checkout of the Nix repo, make sure you're on `master` and run
|
||||
`git pull`.
|
||||
|
||||
* Compile the release notes by running
|
||||
|
||||
```console
|
||||
$ git checkout -b release-notes
|
||||
$ VERSION=X.YY ./maintainers/release-notes
|
||||
```
|
||||
|
||||
where `X.YY` is *without* the patch level, e.g. `2.12` rather than ~~`2.12.0`~~.
|
||||
|
||||
A commit is created.
|
||||
|
||||
* Proof-read / edit / rearrange the release notes if needed. Breaking changes
|
||||
and highlights should go to the top.
|
||||
|
||||
* Push.
|
||||
|
||||
```console
|
||||
$ git push --set-upstream $REMOTE release-notes
|
||||
```
|
||||
|
||||
* Create a PR for `release-notes`.
|
||||
|
||||
* Wait for the PR to be merged.
|
||||
|
||||
* Create a branch for the release:
|
||||
|
||||
```console
|
||||
$ git checkout master
|
||||
$ git pull
|
||||
$ git checkout -b $VERSION-maintenance
|
||||
```
|
||||
|
||||
* Mark the release as official:
|
||||
|
||||
```console
|
||||
$ sed -e 's/officialRelease = false;/officialRelease = true;/' -i flake.nix
|
||||
$ sed -e '/rl-next.md/ d' -i doc/manual/src/SUMMARY.md
|
||||
```
|
||||
|
||||
This removes the link to `rl-next.md` from the manual and sets
|
||||
`officialRelease = true` in `flake.nix`.
|
||||
|
||||
* Commit
|
||||
|
||||
* Push the release branch:
|
||||
|
||||
```console
|
||||
$ git push --set-upstream origin $VERSION-maintenance
|
||||
```
|
||||
|
||||
* Create a jobset for the release branch on Hydra as follows:
|
||||
|
||||
* Go to the jobset of the previous release
|
||||
(e.g. https://hydra.nixos.org/jobset/nix/maintenance-2.11).
|
||||
|
||||
* Select `Actions -> Clone this jobset`.
|
||||
|
||||
* Set identifier to `maintenance-$VERSION`.
|
||||
|
||||
* Set description to `$VERSION release branch`.
|
||||
|
||||
* Set flake URL to `github:NixOS/nix/$VERSION-maintenance`.
|
||||
|
||||
* Hit `Create jobset`.
|
||||
|
||||
* Wait for the new jobset to evaluate and build. If impatient, go to
|
||||
the evaluation and select `Actions -> Bump builds to front of
|
||||
queue`.
|
||||
|
||||
* When the jobset evaluation has succeeded building, take note of the
|
||||
evaluation ID (e.g. `1780832` in
|
||||
`https://hydra.nixos.org/eval/1780832`).
|
||||
|
||||
* Tag the release and upload the release artifacts to
|
||||
[`releases.nixos.org`](https://releases.nixos.org/) and [Docker Hub](https://hub.docker.com/):
|
||||
|
||||
```console
|
||||
$ IS_LATEST=1 ./maintainers/upload-release.pl <EVAL-ID>
|
||||
```
|
||||
|
||||
Note: `IS_LATEST=1` causes the `latest-release` branch to be
|
||||
force-updated. This is used by the `nixos.org` website to get the
|
||||
[latest Nix manual](https://nixos.org/manual/nixpkgs/unstable/).
|
||||
|
||||
TODO: This script requires the right AWS credentials. Document.
|
||||
|
||||
TODO: This script currently requires a
|
||||
`/home/eelco/Dev/nix-pristine`.
|
||||
|
||||
TODO: trigger nixos.org netlify: https://docs.netlify.com/configure-builds/build-hooks/
|
||||
|
||||
* Prepare for the next point release by editing `.version` to
|
||||
e.g.
|
||||
|
||||
```console
|
||||
$ echo 2.12.1 > .version
|
||||
$ git commit -a -m 'Bump version'
|
||||
$ git push
|
||||
```
|
||||
|
||||
Commit and push this to the maintenance branch.
|
||||
|
||||
* Bump the version of `master`:
|
||||
|
||||
```console
|
||||
$ git checkout master
|
||||
$ git pull
|
||||
$ NEW_VERSION=2.13.0
|
||||
$ echo $NEW_VERSION > .version
|
||||
$ git checkout -b bump-$NEW_VERSION
|
||||
$ git commit -a -m 'Bump version'
|
||||
$ git push --set-upstream origin bump-$NEW_VERSION
|
||||
```
|
||||
|
||||
Make a pull request and auto-merge it.
|
||||
|
||||
* Create a milestone for the next release, move all unresolved issues
|
||||
from the previous milestone, and close the previous milestone. Set
|
||||
the date for the next milestone 6 weeks from now.
|
||||
|
||||
* Create a backport label.
|
||||
|
||||
* Post an [announcement on Discourse](https://discourse.nixos.org/c/announcements/8), including the contents of
|
||||
`rl-$VERSION.md`.
|
||||
|
||||
## Creating a point release
|
||||
|
||||
* Checkout.
|
||||
|
||||
```console
|
||||
$ git checkout XX.YY-maintenance
|
||||
```
|
||||
|
||||
* Determine the next patch version.
|
||||
|
||||
```console
|
||||
$ export VERSION=XX.YY.ZZ
|
||||
```
|
||||
|
||||
* Update release notes.
|
||||
|
||||
```console
|
||||
$ ./maintainers/release-notes
|
||||
```
|
||||
|
||||
* Push.
|
||||
|
||||
```console
|
||||
$ git push
|
||||
```
|
||||
|
||||
* Wait for the desired evaluation of the maintenance jobset to finish
|
||||
building.
|
||||
|
||||
* Run
|
||||
|
||||
```console
|
||||
$ IS_LATEST=1 ./maintainers/upload-release.pl <EVAL-ID>
|
||||
```
|
||||
|
||||
Omit `IS_LATEST=1` when creating a point release that is not on the
|
||||
most recent stable branch. This prevents `nixos.org` to going back
|
||||
to an older release.
|
||||
|
||||
* Bump the version number of the release branch as above (e.g. to
|
||||
`2.12.2`).
|
||||
|
||||
## Recovering from mistakes
|
||||
|
||||
`upload-release.pl` should be idempotent. For instance a wrong `IS_LATEST` value can be fixed that way, by running the script on the actual latest release.
