ff8fd21304 nixos-rebuild: use sudo when whoami != root
Currently, executing `nixos-rebuild switch` as a non-root user will
result in a somewhat confusing error about being unable to link a
profile to a nix store path. This is not ideal, especially as we already
have most of the code to handle this properly and use `sudo` to elevate
permissions to install.

This is preferrable for flakes (better eval caching), and also more
intuitive for new users.

Hello dear reporter,
Building this package twice does not produce the bit-by-bit identical result each time, making it harder to detect CI breaches. You can read more about this at https://reproducible-builds.org/ .
Thank you for bringing attention to this issue. Your insights are valuable to
us, and we appreciate the time you took to document the problem.
Fixing bit-by-bit reproducibility also has additional advantages, such as avoiding hard-to-reproduce bugs, making content-addressed storage more effective and reducing rebuilds in such systems.
I wanted to kindly point out that in this issue template, it would be beneficial
to replace the placeholder `<package>` with the actual, canonical name of the
package you're reporting the issue for. Doing so will provide better context and
facilitate quicker troubleshooting for anyone who reads this issue in the
future.
Best regards
-->
Building this package multiple times does not yield bit-by-bit identical
results, complicating the detection of Continuous Integration (CI) breaches. For
more information on this issue, visit
[reproducible-builds.org](https://reproducible-builds.org/).
Fixing bit-by-bit reproducibility also has additional advantages, such as
avoiding hard-to-reproduce bugs, making content-addressed storage more effective
and reducing rebuilds in such systems.
## Steps To Reproduce
In the following steps, replace `<package>` with the canonical name of the
package.
### 1. Build the package
This step will build the package. Specific arguments are passed to the command
to keep the build artifacts so we can compare them in case of differences.
Execute the following command:
### Steps To Reproduce
```
nix-build '<nixpkgs>' -A <package> && nix-build '<nixpkgs>' -A <package> --check --keep-failed
nix-build '<nixpkgs>' -A ... --check --keep-failed
```
Or using the new command line style:
You can use `diffoscope` to analyze the differences in the output of the two builds.
To view the build log of the build that produced the artifact in the binary cache:
```
nix build nixpkgs#<package> && nix build nixpkgs#<package> --rebuild --keep-failed
nix-store --read-log $(nix-instantiate '<nixpkgs>' -A ...)
```
### 2. Compare the build artifacts
### Additional context
If the previous command completes successfully, no differences were found and
there's nothing to do, builds are reproducible.
If it terminates with the error message `error: derivation '<X>' may not be
deterministic: output '<Y>' differs from '<Z>'`, use `diffoscope` to investigate
the discrepancies between the two build outputs. You may need to add the
`--exclude-directory-metadata recursive` option to ignore files and directories
metadata (*e.g. timestamp*) differences.
```
nix run nixpkgs#diffoscopeMinimal -- --exclude-directory-metadata recursive <Y> <Z>
```
### 3. Examine the build log
To examine the build log, use:
```
nix-store --read-log $(nix-instantiate '<nixpkgs>' -A <package>)
```
Or with the new command line style:
```
nix log $(nix path-info --derivation nixpkgs#<package>)
```
## Additional context
(please share the relevant fragment of the diffoscope output here, and any additional analysis you may have done)
## Notify maintainers

# GitHub Actions Workflows
Some architectural notes about key decisions and concepts in our workflows:
- Instead of `pull_request` we use [`pull_request_target`](https://docs.github.com/actions/writing-workflows/choosing-when-your-workflow-runs/events-that-trigger-workflows#pull_request_target) for all PR-related workflows.
This has the advantage that those workflows will run without prior approval for external contributors.
- Running on `pull_request_target` also optionally provides us with a GH_TOKEN with elevated privileges (write access), which we need to do things like adding labels, requesting reviewers or pushing branches.
**Note about security:** We need to be careful to limit the scope of elevated privileges as much as possible.
Thus they should be lowered to the minimum with `permissions: {}` in every workflow by default.
- By definition `pull_request_target` runs in the context of the **base** of the pull request.
This means, that the workflow files to run will be taken from the base branch, not the PR, and actions/checkout will not checkout the PR, but the base branch, by default.
To protect our secrets, we need to make sure to **never execute code** from the pull request and always evaluate or build nix code from the pull request with the **sandbox enabled**.
- To test the pull request's contents, we checkout the "test merge commit".
This is a temporary commit that GitHub creates automatically as "what would happen, if this PR was merged into the base branch now?".
The checkout could be done via the virtual branch `refs/pull/<pr-number>/merge`, but doing so would cause failures when this virtual branch doesn't exist (anymore).
This can happen when the PR has conflicts, in which case the virtual branch is not created, or when the PR is getting merged while workflows are still running, in which case the branch won't exist anymore at the time of checkout.
Thus, we use the `get-merge-commit.yml` workflow to check whether the PR is mergeable and the test merge commit exists and only then run the relevant jobs.
- Various workflows need to make comparisons against the base branch.
In this case, we checkout the parent of the "test merge commit" for best results.
Note, that this is not necessarily the same as the default commit that actions/checkout would use, which is also a commit from the base branch (see above), but might be older.
## Terminology
- **base commit**: The pull_request_target event's context commit, i.e. the base commit given by GitHub Actions.
Same as `github.event.pull_request.base.sha`.
- **head commit**: The HEAD commit in the pull request's branch.
Same as `github.event.pull_request.head.sha`.
- **merge commit**: The temporary "test merge commit" that GitHub Actions creates and updates for the pull request.
Same as `refs/pull/${{ github.event.pull_request.number }}/merge`.
- **target commit**: The base branch's parent of the "test merge commit" to compare against.
## Concurrency Groups
We use [GitHub's Concurrency Groups](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/control-the-concurrency-of-workflows-and-jobs) to cancel older jobs on pushes to Pull Requests.
When two workflows are in the same group, a newer workflow cancels an older workflow.
Thus, it is important how to construct the group keys:
- Because we want to run jobs for different events at same time, we add `github.event_name` to the key.
This is the case for the `pull_request` which runs on changes to the workflow files to test the new files and the same workflow from the base branch run via `pull_request_event`.
- We don't want workflows of different Pull Requests to cancel each other, so we include `github.event.pull_request.number`.
The [GitHub docs](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/control-the-concurrency-of-workflows-and-jobs#example-using-a-fallback-value) show using `github.head_ref` for this purpose, but this doesn't work well with forks: Different users could have the same head branch name in their forks and run CI for their PRs at the same time.
- Sometimes, there is no `pull_request.number`.
To ensure non-PR runs are never cancelled, we add a fallback of `github.run_id`.
This is a unique value for each workflow run.
- Of course, we run multiple workflows at the same time, so we add `github.workflow` to the key.
Otherwise workflows would cancel each other.
- There is a special case for reusable workflows called via `workflow_call` - they will have `github.workflow` set to their parent workflow's name.
Thus, they would cancel each other.
That's why we additionally hardcode the name of the workflow as well.
This results in a key with the following semantics:
```
<running-workflow>-<triggering-workflow>-<triggered-event>-<pull-request/fallback>
```

# Some workflows depend on the base branch of the PR, but changing the base branch is not included in the default trigger events, which would be `opened`, `synchronize` or `reopened`.
# Instead it causes an `edited` event.
# Since `edited` is also triggered when PR title/body is changed, we use this wrapper workflow, to run the other workflows conditionally only.
# There are already feature requests for adding a `base_changed` event:
# - https://github.com/orgs/community/discussions/35058
# - https://github.com/orgs/community/discussions/64119

# Instead of adding this to each workflow's pull_request_target event, we trigger this in a separate workflow.
# This has the advantage, that we can actually skip running those jobs for simple edits like changing the title or description.

# Contributing to Nixpkgs
# How to contribute
This document is for people wanting to contribute to the implementation of Nixpkgs.
This involves interacting with implementation changes that are proposed using [GitHub](https://github.com/) [pull requests](https://docs.github.com/pull-requests) to the [Nixpkgs](https://github.com/nixos/nixpkgs/) repository (which you're in right now).
Note: contributing implies licensing those contributions
under the terms of [COPYING](COPYING), which is an MIT-like license.
As such, a GitHub account is recommended, which you can sign up for [here](https://github.com/signup).
See [here](https://discourse.nixos.org/t/about-the-patches-category/477) for how to contribute without a GitHub account.
## Opening issues
Additionally this document assumes that you already know how to use GitHub and Git.
If that's not the case, we recommend learning about it first [here](https://docs.github.com/en/get-started/quickstart/hello-world).
* Make sure you have a [GitHub account](https://github.com/signup/free)
* Make sure there is no open issue on the topic
* [Submit a new issue](https://github.com/NixOS/nixpkgs/issues/new/choose) by choosing the kind of topic and fill out the template
## Overview
[overview]: #overview
## Submitting changes
This file contains general contributing information, but individual parts also have more specific information to them in their respective `README.md` files, linked here:
- [`lib`](./lib/README.md): Sources and documentation of the [library functions](https://nixos.org/manual/nixpkgs/stable/#chap-functions)
- [`maintainers`](./maintainers/README.md): Nixpkgs maintainer and team listings, maintainer scripts
- [`pkgs`](./pkgs/README.md): Package and [builder](https://nixos.org/manual/nixpkgs/stable/#part-builders) definitions
- [`doc`](./doc/README.md): Sources and infrastructure for the [Nixpkgs manual](https://nixos.org/manual/nixpkgs/stable/)
- [`nixos`](./nixos/README.md): Implementation of [NixOS](https://nixos.org/manual/nixos/stable/)
Read the ["Submitting changes"](https://nixos.org/nixpkgs/manual/#chap-submitting-changes) section of the nixpkgs manual. It explains how to write, test, and iterate on your change, and which branch to base your pull request against.
# How to's
Below is a short excerpt of some points in there:
## How to create pull requests
[pr-create]: #how-to-create-pull-requests
* Format the commit messages in the following way:
This section describes in some detail how changes can be made and proposed with pull requests.
```
(pkg-name | nixos/<module>): (from -> to | init at version | refactor | etc)
> [!Note]
> Be aware that contributing implies licensing those contributions under the terms of [COPYING](./COPYING), an MIT-like license.
0. Set up a local version of Nixpkgs to work with using GitHub and Git
1. [Fork](https://docs.github.com/en/get-started/quickstart/fork-a-repo#forking-a-repository) the [Nixpkgs repository](https://github.com/nixos/nixpkgs/).
1. [Clone the forked repository](https://docs.github.com/en/get-started/quickstart/fork-a-repo#cloning-your-forked-repository) into a local `nixpkgs` directory.
1. [Configure the upstream Nixpkgs repository](https://docs.github.com/en/get-started/quickstart/fork-a-repo#configuring-git-to-sync-your-fork-with-the-upstream-repository).
1. Figure out the branch that should be used for this change by going through [this section][branch].
If in doubt use `master`, that's where most changes should go.
This can be changed later by [rebasing][rebase].
2. Create and switch to a new Git branch, ideally such that:
- The name of the branch hints at the change you'd like to implement, e.g. `update-hello`.
- The base of the branch includes the most recent changes on the base branch from step 1, we'll assume `master` here.
```bash
# Make sure you have the latest changes from upstream Nixpkgs
git fetch upstream
# Create and switch to a new branch based off the master branch in Nixpkgs
git switch --create update-hello upstream/master
```
To avoid having to download and build potentially many derivations, at the expense of using a potentially outdated version, you can base the branch off a specific [Git commit](https://www.git-scm.com/docs/gitglossary#def_commit) instead:
- The commit of the latest `nixpkgs-unstable` channel, available [here](https://channels.nixos.org/nixpkgs-unstable/git-revision).
- The commit of a local Nixpkgs downloaded using [nix-channel](https://nixos.org/manual/nix/stable/command-ref/nix-channel), available using `nix-instantiate --eval --expr '(import <nixpkgs/lib>).trivial.revisionWithDefault null'`
- If you're using NixOS, the commit of your NixOS installation, available with `nixos-version --revision`.
Once you have an appropriate commit you can use it instead of `upstream/master` in the above command:
```bash
git switch --create update-hello <the desired base commit>
```
3. Make the desired changes in the local Nixpkgs repository using an editor of your choice.
Make sure to:
- Adhere to both the [general code conventions][code-conventions], and the code conventions specific to the part you're making changes to.
See the [overview section][overview] for more specific information.
- Test the changes.
See the [overview section][overview] for more specific information.
- If necessary, document the change.
See the [overview section][overview] for more specific information.
4. Commit your changes using `git commit`.
Make sure to adhere to the [commit conventions](#commit-conventions).
Repeat the steps 3-4 as many times as necessary.
Advance to the next step if all the commits (viewable with `git log`) make sense together.
5. Push your commits to your fork of Nixpkgs.
```
git push --set-upstream origin HEAD
```
The above command will output a link that allows you to directly quickly do the next step:
```
remote: Create a pull request for 'update-hello' on GitHub by visiting:
remote: https://github.com/myUser/nixpkgs/pull/new/update-hello
```
6. [Create a pull request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request#creating-the-pull-request) from the new branch in your Nixpkgs fork to the upstream Nixpkgs repository.
Use the branch from step 2 as the pull requests base branch.
Go through the [pull request template](#pull-request-template) in the pre-filled default description.
7. Respond to review comments, potential CI failures and potential merge conflicts by updating the pull request.
Always keep the pull request in a mergeable state.
This process is covered in more detail from the non-technical side in [I opened a PR, how do I get it merged?](#i-opened-a-pr-how-do-i-get-it-merged).
The custom [OfBorg](https://github.com/NixOS/ofborg) CI system will perform various checks to help ensure code quality, whose results you can see at the bottom of the pull request.
See [the OfBorg Readme](https://github.com/NixOS/ofborg#readme) for more details.
- To add new commits, repeat steps 3-4 and push the result using
```
git push
```
- To change existing commits you will have to [rewrite Git history](https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History).
Useful Git commands that can help a lot with this are `git commit --patch --amend` and `git rebase --interactive`.
With a rewritten history you need to force-push the commits using
```
git push --force-with-lease
```
- In case of merge conflicts you will also have to [rebase the branch](https://git-scm.com/book/en/v2/Git-Branching-Rebasing) on top of current `master`.
Sometimes this can be done [on GitHub directly](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/keeping-your-pull-request-in-sync-with-the-base-branch#updating-your-pull-request-branch), but if not you will have to rebase locally using
```
git fetch upstream
git rebase upstream/master
git push --force-with-lease
```
- If you need to change the base branch of the pull request, you can do so by [rebasing][rebase].
8. If your pull request is merged and [acceptable for releases][release-acceptable] you may [backport][pr-backport] the pull request.
### Pull request template
[pr-template]: #pull-request-template
The pull request template helps determine what steps have been made for a contribution so far, and will help guide maintainers on the status of a change. The motivation section of the PR should include any extra details the title does not address and link any existing issues related to the pull request.
When a PR is created, it will be pre-populated with some checkboxes detailed below:
#### Tested using sandboxing
When sandbox builds are enabled, Nix will set up an isolated environment for each build process.
It is used to remove further hidden dependencies set by the build environment to improve reproducibility.
This includes access to the network during the build outside of `fetch*` functions and files outside the Nix store.
Depending on the operating system, access to other resources is blocked as well (e.g., inter-process communication is isolated on Linux); see [sandbox](https://nixos.org/manual/nix/stable/command-ref/conf-file#conf-sandbox) in the Nix manual for details.
In pull requests for [nixpkgs](https://github.com/NixOS/nixpkgs/) people are asked to test builds with sandboxing enabled (see `Tested using sandboxing` in the pull request template) because in [Hydra](https://nixos.org/hydra/) sandboxing is also used.
If you are on Linux, sandboxing is enabled by default.
On other platforms, sandboxing is disabled by default due to a small performance hit on each build.
Please enable sandboxing **before** building the package by adding the following to: `/etc/nix/nix.conf`:
```ini
sandbox = true
(Motivation for change. Link to release notes. Additional information.)
```
#### Built on platform(s)
For consistency, there should not be a period at the end of the commit message's summary line (the first line of the commit message).
Many Nix packages are designed to run on multiple platforms. As such, its important to let the maintainer know which platforms your changes have been tested on. Its not always practical to test a change on all platforms, and is not required for a pull request to be merged. Only check the systems you tested the build on in this section.
Examples:
#### Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
* nginx: init at 2.0.1
* firefox: 54.0.1 -> 55.0
https://www.mozilla.org/en-US/firefox/55.0/releasenotes/
* nixos/hydra: add bazBaz option
Packages with automated tests are much more likely to be merged in a timely fashion because it doesnt require as much manual testing by the maintainer to verify the functionality of the package. If there are existing tests for the package, they should be run to verify your changes do not break the tests. Tests can only be run on Linux. For more details on writing and running tests, see the [section in the NixOS manual](https://nixos.org/nixos/manual/index.html#sec-nixos-tests).
Dual baz behavior is needed to do foo.
* nixos/nginx: refactor config generation
#### Tested compilation of all pkgs that depend on this change using `nixpkgs-review`
The old config generation system used impure shell scripts and could break in specific circumstances (see #1234).
If you are modifying a package, you can use `nixpkgs-review` to make sure all packages that depend on the updated package still compile correctly. The `nixpkgs-review` utility can look for and build all dependencies either based on uncommitted changes with the `wip` option or specifying a GitHub pull request number.
* `meta.description` should:
* Be short, just one sentence.
* Be capitalized.
* Not start with the package name.
* More generally, it should not refer to the package name.
* Not end with a period (or any punctuation for that matter).
* `meta.license` must be set and fit the upstream license.
* If there is no upstream license, `meta.license` should default to `lib.licenses.unfree`.
* If in doubt, try to contact the upstream developers for clarification.
* `meta.maintainers` must be set.
Review changes from pull request number 12345:
See the nixpkgs manual for more details on [standard meta-attributes](https://nixos.org/nixpkgs/manual/#sec-standard-meta-attributes).
```ShellSession
nix-shell -p nixpkgs-review --run "nixpkgs-review pr 12345"
```
## Writing good commit messages
Alternatively, with flakes (and analogously for the other commands below):
In addition to writing properly formatted commit messages, it's important to include relevant information so other developers can later understand *why* a change was made. While this information usually can be found by digging code, mailing list/Discourse archives, pull request discussions or upstream changes, it may require a lot of work.
```ShellSession
nix run nixpkgs#nixpkgs-review -- pr 12345
```
Package version upgrades usually allow for simpler commit messages, including attribute name, old and new version, as well as a reference to the relevant release notes/changelog. Every once in a while a package upgrade requires more extensive changes, and that subsequently warrants a more verbose message.
Review uncommitted changes:
Pull requests should not be squash merged in order to keep complete commit messages and GPG signatures intact and must not be when the change doesn't make sense as a single commit.
This means that, when addressing review comments in order to keep the pull request in an always mergeable status, you will sometimes need to rewrite your branch's history and then force-push it with `git push --force-with-lease`.
Useful git commands that can help a lot with this are `git commit --patch --amend` and `git rebase --interactive`. For more details consult the git man pages or online resources like [git-rebase.io](https://git-rebase.io/) or [The Pro Git Book](https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History).
```ShellSession
nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
```
Review changes from last commit:
```ShellSession
nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD"
```
#### Tested execution of all binary files (usually in `./result/bin/`)
Its important to test any executables generated by a build when you change or create a package in nixpkgs. This can be done by looking in `./result/bin` and running any files in there, or at a minimum, the main executable for the package. For example, if you make a change to texlive, you probably would only check the binaries associated with the change you made rather than testing all of them.
#### Meets Nixpkgs contribution standards
The last checkbox is about whether it fits the guidelines in this `CONTRIBUTING.md` file. This document has detailed information on standards the Nix community has for commit messages, reviews, licensing of contributions you make to the project, etc... Everyone should read and understand the standards the community has for contributing before submitting a pull request.
### Rebasing between branches (i.e. from master to staging)
[rebase]: #rebasing-between-branches-ie-from-master-to-staging
## Rebasing between branches (i.e. from master to staging)
From time to time, changes between branches must be rebased, for example, if the
number of new rebuilds they would cause is too large for the target branch.
number of new rebuilds they would cause is too large for the target branch. When
rebasing, care must be taken to include only the intended changes, otherwise
many CODEOWNERS will be inadvertently requested for review. To achieve this,
rebasing should not be performed directly on the target branch, but on the merge
base between the current and target branch.
In the following example, we assume that the current branch, called `feature`,
is based on `master`, and we rebase it onto the merge base between
`master` and `staging` so that the PR can be retargeted to
`staging`. The example uses `upstream` as the remote for `NixOS/nixpkgs.git`

## How to backport pull requests
[pr-backport]: #how-to-backport-pull-requests
## Backporting changes
Once a pull request has been merged into `master`, a backport pull request to the corresponding `release-YY.MM` branch can be created either automatically or manually.
Follow these steps to backport a change into a release branch in compliance with the [commit policy](https://nixos.org/nixpkgs/manual/#submitting-changes-stable-release-branches).
### Automatically backporting changes
You can add a label such as `backport release-22.11` to a PR, so that merging it will
automatically create a backport (via [a GitHub Action](.github/workflows/backport.yml)).
This also works for PR's that have already been merged, and might take a couple of minutes to trigger.
> [!Note]
> You have to be a [Nixpkgs maintainer](./maintainers) to automatically create a backport pull request.
You can also create the backport manually:
Add the [`backport release-YY.MM` label](https://github.com/NixOS/nixpkgs/labels?q=backport) to the pull request on the `master` branch.
This will cause [a GitHub Action](.github/workflows/backport.yml) to open a pull request to the `release-YY.MM` branch a few minutes later.
This can be done on both open or already merged pull requests.
1. Take note of the commits in which the change was introduced into `master` branch.
2. Check out the target _release branch_, e.g. `release-22.11`. Do not use a _channel branch_ like `nixos-22.11` or `nixpkgs-22.11-darwin`.
3. Create a branch for your change, e.g. `git checkout -b backport`.
4. When the reason to backport is not obvious from the original commit message, use `git cherry-pick -xe <original commit>` and add a reason. Otherwise use `git cherry-pick -x <original commit>`. That's fine for minor version updates that only include security and bug fixes, commits that fixes an otherwise broken package or similar. Please also ensure the commits exists on the master branch; in the case of squashed or rebased merges, the commit hash will change and the new commits can be found in the merge message at the bottom of the master pull request.
5. Push to GitHub and open a backport pull request. Make sure to select the release branch (e.g. `release-22.11`) as the target branch of the pull request, and link to the pull request in which the original change was committed to `master`. The pull request title should be the commit title with the release version as prefix, e.g. `[22.11]`.
6. When the backport pull request is merged and you have the necessary privileges you can also replace the label `9.needs: port to stable` with `8.has: port to stable` on the original pull request. This way maintainers can keep track of missing backports easier.
### Manually backporting changes
## Criteria for Backporting changes
To manually create a backport pull request, follow [the standard pull request process][pr-create], with these notable differences:
- Use `release-YY.MM` for the base branch, both for the local branch and the pull request.
> [!Warning]
> Do not use the `nixos-YY.MM` branch, that is a branch pointing to the tested release channel commit
- Instead of manually making and committing the changes, use [`git cherry-pick -x`](https://git-scm.com/docs/git-cherry-pick) for each commit from the pull request you'd like to backport.
Either `git cherry-pick -x <commit>` when the reason for the backport is obvious (such as minor versions, fixes, etc.), otherwise use `git cherry-pick -xe <commit>` to add a reason for the backport to the commit message.
Here is [an example](https://github.com/nixos/nixpkgs/commit/5688c39af5a6c5f3d646343443683da880eaefb8) of this.
> [!Warning]
> Ensure the commits exists on the master branch.
> In the case of squashed or rebased merges, the commit hash will change and the new commits can be found in the merge message at the bottom of the master pull request.
- In the pull request description, link to the original pull request to `master`.
The pull request title should include `[YY.MM]` matching the release you're backporting to.
- When the backport pull request is merged and you have the necessary privileges you can also replace the label `9.needs: port to stable` with `8.has: port to stable` on the original pull request.
This way maintainers can keep track of missing backports easier.
## How to review pull requests
[pr-review]: #how-to-review-pull-requests
> [!Warning]
> The following section is a draft, and the policy for reviewing is still being discussed in issues such as [#11166](https://github.com/NixOS/nixpkgs/issues/11166) and [#20836](https://github.com/NixOS/nixpkgs/issues/20836).
The Nixpkgs project receives a fairly high number of contributions via GitHub pull requests. Reviewing and approving these is an important task and a way to contribute to the project.
The high change rate of Nixpkgs makes any pull request that remains open for too long subject to conflicts that will require extra work from the submitter or the merger. Reviewing pull requests in a timely manner and being responsive to the comments is the key to avoid this issue. GitHub provides sort filters that can be used to see the [most recently](https://github.com/NixOS/nixpkgs/pulls?q=is%3Apr+is%3Aopen+sort%3Aupdated-desc) and the [least recently](https://github.com/NixOS/nixpkgs/pulls?q=is%3Apr+is%3Aopen+sort%3Aupdated-asc) updated pull requests. We highly encourage looking at [this list of ready to merge, unreviewed pull requests](https://github.com/NixOS/nixpkgs/pulls?q=is%3Apr+is%3Aopen+review%3Anone+status%3Asuccess+-label%3A%222.status%3A+work-in-progress%22+no%3Aproject+no%3Aassignee+no%3Amilestone).
When reviewing a pull request, please always be nice and polite. Controversial changes can lead to controversial opinions, but it is important to respect every community member and their work.
GitHub provides reactions as a simple and quick way to provide feedback to pull requests or any comments. The thumb-down reaction should be used with care and if possible accompanied with some explanation so the submitter has directions to improve their contribution.
When doing a review:
- Aim to drive the proposal to a timely conclusion.
- Focus on the proposed changes to keep the scope of the discussion narrow.
- Help the contributor prioritise their efforts towards getting their change merged.
If you find anything related that could be improved but is not immediately required for acceptance, consider
- Implementing the changes yourself in a follow-up pull request (and request review from the person who inspired you)
- Tracking your idea in an issue
- Offering the original contributor to review a follow-up pull request
- Making concrete [suggestions](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/reviewing-changes-in-pull-requests/incorporating-feedback-in-your-pull-request) in the same pull request.
For example, follow-up changes could involve refactoring code in the affected files.
But please remember not to make such additional considerations a blocker, and communicate that to the contributor, for example by following the [conventional comments](https://conventionalcomments.org/) pattern.
If the related change is essential for the contribution at hand, make clear why you think it is important to address that first.
Pull request reviews should include a list of what has been reviewed in a comment, so other reviewers and mergers can know the state of the review.
All the review template samples provided in this section are generic and meant as examples. Their usage is optional and the reviewer is free to adapt them to their liking.
To get more information about how to review specific parts of Nixpkgs, refer to the documents linked to in the [overview section][overview].
If a pull request contains documentation changes that might require feedback from the documentation team, ping [@NixOS/documentation-team](https://github.com/orgs/nixos/teams/documentation-team) on the pull request.
If you consider having enough knowledge and experience in a topic and would like to be a long-term reviewer for related submissions, please contact the current reviewers for that topic. They will give you information about the reviewing process. The main reviewers for a topic can be hard to find as there is no list, but checking past pull requests to see who reviewed or git-blaming the code to see who committed to that topic can give some hints.
Container system, boot system and library changes are some examples of the pull requests fitting this category.
## How to merge pull requests yourself
[pr-merge]: #how-to-merge-pull-requests
To streamline automated updates, leverage the nixpkgs-merge-bot by simply commenting `@NixOS/nixpkgs-merge-bot merge`. The bot will verify if the following conditions are met, refusing to merge otherwise:
- the PR author should be @r-ryantm;
- the commenter that issued the command should be among the package maintainers;
- the package should reside in `pkgs/by-name`.
Further, nixpkgs-merge-bot will ensure all ofBorg checks (except the Darwin-related ones) are successfully completed before merging the pull request. Should the checks still be underway, the bot patiently waits for ofBorg to finish before attempting the merge again.
For other pull requests, please see [I opened a PR, how do I get it merged?](#i-opened-a-pr-how-do-i-get-it-merged).
In case the PR is stuck waiting for the original author to apply a trivial
change (a typo, capitalisation change, etc.) and the author allowed the members
to modify the PR, consider applying it yourself (or commit the existing review
suggestion). You should pay extra attention to make sure the addition doesn't go
against the idea of the original PR and would not be opposed by the author.
Anything that does not cause user or downstream dependency regressions can be backported. This includes:
- New Packages / Modules
- Security / Patch updates
- Version updates which include new functionality (but no breaking changes)
- Services which require a client to be up-to-date regardless. (E.g. `spotify`, `steam`, or `discord`)
- Security critical applications (E.g. `firefox`)
## Generating 23.05 Release Notes
<!--
The following paragraphs about how to deal with unactive contributors is just a proposition and should be modified to what the community agrees to be the right policy.
Please note that contributors with commit rights unactive for more than three months will have their commit rights revoked.
note: title unchanged even though we don't need regeneration because extant
PRs will link here. definitely change the title for 23.11 though.
-->
Please see the discussion in [GitHub nixpkgs issue #321665](https://github.com/NixOS/nixpkgs/issues/321665) for information on how to proceed to be granted this level of access.
Documentation in nixpkgs is transitioning to a markdown-centric workflow. In the past release notes required a translation step to convert from markdown to a compatible docbook document, but this is no longer necessary.
In a case a contributor definitively leaves the Nix community, they should create an issue or post on [Discourse](https://discourse.nixos.org) with references of packages and modules they maintain so the maintainership can be taken over by other contributors.
Steps for updating 23.05 Release notes:
# Flow of merged pull requests
1. Edit `nixos/doc/manual/release-notes/rl-2305.section.md` with the desired changes
2. Commit changes to `rl-2305.section.md`.
After a pull request is merged, it eventually makes it to the [official Hydra CI](https://hydra.nixos.org/).
Hydra regularly evaluates and builds Nixpkgs, updating [the official channels](https://channels.nixos.org/) when specific Hydra jobs succeeded.
See [Nix Channel Status](https://status.nixos.org/) for the current channels and their state.
Here's a brief overview of the main Git branches and what channels they're used for:
## Reviewing contributions
- `master`: The main branch, used for the unstable channels such as `nixpkgs-unstable`, `nixos-unstable` and `nixos-unstable-small`.
- `release-YY.MM` (e.g. `release-24.05`): The NixOS release branches, used for the stable channels such as `nixos-24.05`, `nixos-24.05-small` and `nixpkgs-24.05-darwin`.
When a channel is updated, a corresponding Git branch is also updated to point to the corresponding commit.
So e.g. the [`nixpkgs-unstable` branch](https://github.com/nixos/nixpkgs/tree/nixpkgs-unstable) corresponds to the Git commit from the [`nixpkgs-unstable` channel](https://channels.nixos.org/nixpkgs-unstable).
Nixpkgs in its entirety is tied to the NixOS release process, which is documented in the [NixOS Release Wiki](https://nixos.github.io/release-wiki/).
See [this section][branch] to know when to use the release branches.
## Staging
[staging]: #staging
The staging workflow exists to batch Hydra builds of many packages together.
It is coordinated in the [Staging room](https://matrix.to/#/#staging:nixos.org) on Matrix.
It works by directing commits that cause [mass rebuilds][mass-rebuild] to a separate `staging` branch that isn't directly built by Hydra.
Regularly, the `staging` branch is _manually_ merged into a `staging-next` branch to be built by Hydra using the [`nixpkgs:staging-next` jobset](https://hydra.nixos.org/jobset/nixpkgs/staging-next).
The `staging-next` branch should then only receive changes that fix Hydra builds;
**for anything else, ask the [Staging room](https://matrix.to/#/#staging:nixos.org) first**.
Once it is verified that there are no major regressions, it is merged into `master` using [a pull request](https://github.com/NixOS/nixpkgs/pulls?q=head%3Astaging-next).
This is done manually in order to ensure it's a good use of Hydra's computing resources.
By keeping the `staging-next` branch separate from `staging`, this batching does not block developers from merging changes into `staging`.
In order for the `staging` and `staging-next` branches to be up-to-date with the latest commits on `master`, there are regular _automated_ merges from `master` into `staging-next` and `staging`.
This is implemented using GitHub workflows [here](.github/workflows/periodic-merge-6h.yml) and [here](.github/workflows/periodic-merge-24h.yml).
> [!Note]
> Changes must be sufficiently tested before being merged into any branch.
> Hydra builds should not be used as testing platform.

| Automatically merged into | `staging-next` | `staging` | - |
| Manually merged into | - | `master` | `staging-next` |
The staging workflow is used for all main branches, `master` and `release-YY.MM`, with corresponding names:
- `master`/`release-YY.MM`
- `staging`/`staging-YY.MM`
- `staging-next`/`staging-next-YY.MM`
# Conventions
## Branch conventions
<!-- This section is relevant to both contributors and reviewers -->
[branch]: #branch-conventions
Most changes should go to the `master` branch, but sometimes other branches should be used instead.
Use the following decision process to figure out which one it should be:
Is the change [acceptable for releases][release-acceptable] and do you wish to have the change in the release?
- No: Use the `master` branch, do not backport the pull request.
- Yes: Can the change be implemented the same way on the `master` and release branches?
For example, a packages major version might differ between the `master` and release branches, such that separate security patches are required.
- Yes: Use the `master` branch and [backport the pull request](#how-to-backport-pull-requests).
- No: Create separate pull requests to the `master` and `release-XX.YY` branches.
Furthermore, if the change causes a [mass rebuild][mass-rebuild], use the appropriate staging branch instead:
- Mass rebuilds to `master` should go to `staging` instead.
- Mass rebuilds to `release-XX.YY` should go to `staging-XX.YY` instead.
See [this section][staging] for more details about such changes propagate between the branches.
### Changes acceptable for releases
[release-acceptable]: #changes-acceptable-for-releases
Only changes to supported releases may be accepted.
The oldest supported release (`YYMM`) can be found using
```
nix-instantiate --eval -A lib.trivial.oldestSupportedRelease
```
The release branches should generally only receive backwards-compatible changes, both for the Nix expressions and derivations.
Here are some examples of backwards-compatible changes that are okay to backport:
- ✔️ New packages, modules and functions
- ✔️ Security fixes
- ✔️ Package version updates
- ✔️ Patch versions with fixes
- ✔️ Minor versions with new functionality, but no breaking changes
In addition, major package version updates with breaking changes are also acceptable for:
- ✔️ Services that would fail without up-to-date client software, such as `spotify`, `steam`, and `discord`
- ✔️ Security critical applications, such as `firefox` and `chromium`
### Changes causing mass rebuilds
[mass-rebuild]: #changes-causing-mass-rebuilds
Which changes cause mass rebuilds is not formally defined.
In order to help the decision, CI automatically assigns [`rebuild` labels](https://github.com/NixOS/nixpkgs/labels?q=rebuild) to pull requests based on the number of packages they cause rebuilds for.
As a rule of thumb, if the number of rebuilds is **over 500**, it can be considered a mass rebuild.
To get a sense for what changes are considered mass rebuilds, see [previously merged pull requests to the staging branches](https://github.com/NixOS/nixpkgs/issues?q=base%3Astaging+-base%3Astaging-next+is%3Amerged).
## Commit conventions
[commit-conventions]: #commit-conventions
- Create a commit for each logical unit.
- Check for unnecessary whitespace with `git diff --check` before committing.
- If you have commits `pkg-name: oh, forgot to insert whitespace`: squash commits in this case. Use `git rebase -i`.
See [Squashing Commits](https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History#_squashing) for additional information.
- For consistency, there should not be a period at the end of the commit message's summary line (the first line of the commit message).
- When adding yourself as maintainer in the same pull request, make a separate
commit with the message `maintainers: add <handle>`.
Add the commit before those making changes to the package or module.
See [Nixpkgs Maintainers](./maintainers/README.md) for details.
- Make sure you read about any commit conventions specific to the area you're touching. See:
- [Commit conventions](./pkgs/README.md#commit-conventions) for changes to `pkgs`.
- [Commit conventions](./lib/README.md#commit-conventions) for changes to `lib`.
- [Commit conventions](./nixos/README.md#commit-conventions) for changes to `nixos`.
- [Commit conventions](./doc/README.md#commit-conventions) for changes to `doc`, the Nixpkgs manual.
### Writing good commit messages
[writing-good-commit-messages]: #writing-good-commit-messages
In addition to writing properly formatted commit messages, it's important to include relevant information so other developers can later understand *why* a change was made. While this information usually can be found by digging code, mailing list/Discourse archives, pull request discussions or upstream changes, it may require a lot of work.
Package version upgrades usually allow for simpler commit messages, including attribute name, old and new version, as well as a reference to the relevant release notes/changelog. Every once in a while a package upgrade requires more extensive changes, and that subsequently warrants a more verbose message.
Pull requests should not be squash merged in order to keep complete commit messages and GPG signatures intact and must not be when the change doesn't make sense as a single commit.
## Code conventions
[code-conventions]: #code-conventions
### Release notes
If you removed packages or made some major NixOS changes, write about it in the release notes for the next stable release in [`nixos/doc/manual/release-notes`](./nixos/doc/manual/release-notes).
### File naming and organisation
Names of files and directories should be in lowercase, with dashes between words — not in camel case. For instance, it should be `all-packages.nix`, not `allPackages.nix` or `AllPackages.nix`.
### Formatting
CI [enforces](./.github/workflows/check-nix-format.yml) all Nix files to be
formatted using the [official Nix formatter](https://github.com/NixOS/nixfmt).
You can ensure this locally using either of these commands:
```
nix-shell --run treefmt
nix develop --command treefmt
nix fmt
```
If you're starting your editor in `nix-shell` or `nix develop`,
you can also set it up to automatically format the file with `treefmt` on save.
If you have any problems with formatting, please ping the
[formatting team](https://nixos.org/community/teams/formatting/) via
[@NixOS/nix-formatting](https://github.com/orgs/NixOS/teams/nix-formatting).
### Syntax
- Set up [editorconfig](https://editorconfig.org/) for your editor, such that [the settings](./.editorconfig) are automatically applied.
- Use `lowerCamelCase` for variable names, not `UpperCamelCase`. Note, this rule does not apply to package attribute names, which instead follow the rules in [package naming](./pkgs/README.md#package-naming).
- Functions should list their expected arguments as precisely as possible. That is, write
```nix
{ stdenv, fetchurl, perl }: <...>
```
instead of
```nix
args: with args; <...>
```
or
```nix
{ stdenv, fetchurl, perl, ... }: <...>
```
For functions that are truly generic in the number of arguments (such as wrappers around `mkDerivation`) that have some required arguments, you should write them using an `@`-pattern:
```nix
{ stdenv, doCoverageAnalysis ? false, ... } @ args:
stdenv.mkDerivation (args // {
foo = if doCoverageAnalysis then "bla" else "";
})
```
instead of
```nix
args:
args.stdenv.mkDerivation (args // {
foo = if args ? doCoverageAnalysis && args.doCoverageAnalysis then "bla" else "";
})
```
- Unnecessary string conversions should be avoided. Do
```nix
{
rev = version;
}
```
instead of
```nix
{
rev = "${version}";
}
```
- Building lists conditionally _should_ be done with `lib.optional(s)` instead of using `if cond then [ ... ] else null` or `if cond then [ ... ] else [ ]`.
```nix
{
buildInputs = lib.optional stdenv.hostPlatform.isDarwin iconv;
}
```
instead of
```nix
{
buildInputs = if stdenv.hostPlatform.isDarwin then [ iconv ] else null;
}
```
As an exception, an explicit conditional expression with null can be used when fixing a important bug without triggering a mass rebuild.
If this is done a follow up pull request _should_ be created to change the code to `lib.optional(s)`.
# Practical contributing advice
To contribute effectively and efficiently, you need to be aware of how the contributing process generally works.
This section aims to document the process as we live it in Nixpkgs to set expectations right and give practical tips on how to work with it.
## I opened a PR, how do I get it merged?
[i-opened-a-pr-how-do-i-get-it-merged]:#i-opened-a-pr-how-do-i-get-it-merged
In order for your PR to be merged, someone with merge permissions on the repository ("committer") needs to review and merge it.
Because the group of people with merge permissions is mostly a collection of independent unpaid volunteers who do this in their own free time, this can take some time to happen.
It is entirely normal for your PR to sit around without any feedback for days, weeks or sometimes even months.
We strive to avoid the latter cases of course but the reality of it is that this does happen quite frequently.
Even when you get feedback, follow-up feedback may take similarly long.
Don't be intimidated by this and kindly ask for feedback again every so often.
If your change is good it will eventually be merged at some point.
There are some things you can do to help speed up the process of your PR being merged though.
In order to speed the process up, you need to know what needs to happen before a committer will actually hit the merge button.
This section intends to give a little overview and insight of what happens after you create your PR.
### The committer's perspective
PRs have varying quality and even the best people make mistakes.
It is the role of the committer team to assess whether any PR's changes are good changes or not.
In order for any PR to be merged, at least one committer needs to be convinced of its quality enough to merge it.
Committers typically assess three aspects of your PR:
1. Whether the change's intention is necessary and desirable
2. Whether the code quality of your changes is good
3. Whether the artefacts produced by the code are good
If you want your PR to get merged quickly and smoothly, it is in your best interest to help convince committers in these three aspects.
### How to help committers assess your PR
For the committer to judge your intention, it's best to explain why you've made your change.
This does not apply to trivial changes like version updates because the intention is obvious (though linking the changelog is appreciated).
For any more nuanced changed or even major version upgrades, it helps if you explain the background behind your change a bit.
E.g. if you're adding a package, explain what it is and why it should be in Nixpkgs.
This goes hand in hand with [Writing good commit messages](#writing-good-commit-messages).
For the code quality assessment, you cannot do anything yourself as only the committer can do this and they already have your code to look at.
In order to minimise the need for back and forth though, do take a look over your code changes yourself and try to put yourself into the shoes of someone who didn't just write that code.
Would you immediately know what the code does or why it is needed by glancing at it?
If not, reviewers will notice this and will ask you to clarify the code by refactoring it and/or adding a few explanations in code comments.
Doing this preemptively can save you and the committer a lot of time.
To better convey the "story" of your change, consider dividing your change into multiple atomic commits.
There is a balance to strike however: over-fragmentation causes friction.
The code artefacts are the hardest for committers to assess because PRs touch all sorts of components: applications, libraries, NixOS modules, editor plugins and many many other things.
Any individual committer can only really assess components that they themselves know how to use however and yet they must still be convinced somehow.
There isn't a good generic solution to this but there are some ways easing the committer's job here:
- Provide smoke tests that the committer can run without much research or setup.
Committers usually don't have the time or interest to learn how your component works and how they could test its functionality.
If you can provide a quick guide on how to use the component in a meaningful way or a ready-made command that demonstrates that the component works as expected, the committer can easily convince themselves that your change is good.
If it can be automated, you could even turn this smoke test into an automated NixOS test which reviewers could simply run via Nix.
- Invite other users of the component to try it out and report their findings.
If a committer sees the testimonials of other users trying your change and it works as expected for them, that too can convince the committer of your PR's quality.
- Describe what you have done to test your PR.
If you can convince the committer that you have done sufficient quality assurance on your changes and they trust your report, this too can convince them of your PR's quality, albeit not as strongly as the methods above.
- Become a maintainer of the component.
This isn't something you can do on your first few PRs touching a component but listed maintainers generally receive more trust when it comes to changes to their maintained components and committers may opt to merge changes without deeper review when they see they're done by their respective maintainer.
Even if you adhere to all of these recommendations, it is still quite possible for your PR to be forgotten or abandoned by any given committer.
Please remain mindful of the fact that they are doing this on their own volition and unpaid in their free time and therefore [owe you nothing](https://mikemcquaid.com/open-source-maintainers-owe-you-nothing/).
Causing a stink in such a situation is a surefire way to get any other potential committer to not want to look at your PR either.
Ask them nicely whether they still intend to review your PR and find yourself another committer to look at your PR if not.
### How can I get a committer to look at my PR?
- Improve skimmability: use a simple descriptive PR title (details go in commit titles) outlining _what_ is done and _why_.
- Improve discoverability: apply all relevant labels, tick all relevant PR body checkboxes.
- Wait. Reviewers frequently browse open PRs and may happen to run across yours and take a look.
- Get non-committers to review/approve. Many committers filter open PRs for low-hanging fruit that are already been reviewed.
- [@-mention](https://github.blog/news-insights/mention-somebody-they-re-notified/) someone and ask them nicely
- Post in one of the channels made for this purpose if there has been no activity for at least one week
- The current "PRs ready for review" or "PRs already reviewed" threads in the [NixOS Discourse](https://discourse.nixos.org/c/dev/14) (of course choose the one that applies to your situation)
- The [Nixpkgs Review Requests Matrix room](https://matrix.to/#/#review-requests:nixos.org).
### CI failed or got stuck on my PR, what do I do?
First ensure that the failure is actually related to your change.
Sometimes, the CI system simply has a hiccup or the check was broken by someone else before you made your changes.
Read through the error message; it's usually quite easy to tell whether it is caused by anything you did by checking whether it mentions the component you touched anywhere.
If it is indeed caused by your change, obviously try to fix it.
Don't be afraid of asking for advice if you're uncertain how to do that, others have likely fixed such issues dozens of times and can help you out.
Your PR is unlikely to be merged if it has a known issue and it is the purpose of CI to alert you aswell as reviewers to these issues.
ofBorg builds can often get stuck, particularly in PRs targeting `staging` and in builders for the Darwin platform. Reviewers will know how to handle them or when to ignore them.
Don't worry about it.
If there is a build failure however and it happened due to a package related to your change, you need to investigate it of course.
If ofBorg reveals the build to be broken on some platform and you don't have access to that platform, you should set your package's `meta.broken` accordingly.
When in any doubt, please ask via a comment in your PR or through one of the help channels.
## I received a review on my PR, how do I get it over the finish line?
In the review process, the committer will have left some sort of feedback on your PR.
They may have immediately approved of your PR or even merged it but the more likely case is that they want you to change a few things or that they require further input.
A reviewer may have taken a look at the code and it looked good to them ("Diff LGTM") but they still need to be convinced of the artefact's quality.
They might also be waiting on input from other users of the component or its listed maintainer on whether the intention of your PR makes sense for the component.
If you know of people who could help clarify any of this, please bring the PR to their attention.
The current state of the PR is frequently not clearly communicated, so please don't hesitate to ask about it if it's unclear to you.
It's also possible for the reviewer to not be convinced that your PR is necessary or that the method you've chose to achieve your intention is the right one.
Please explain your intentions and reasoning to the committer in such a case.
There may be constraints you had to work with which they're not aware of or qualities of your approach that they didn't immediately notice.
(If these weren't clear to the reviewer, that's a good sign you should explain them in your commit message or code comments!)
There are some further pitfalls and realities which this section intends to make you aware of.
### Aim to reduce cycles
Please be prepared for it to take a while before the reviewer gets back to you after you respond.
This is simply the reality of community projects at the scale of Nixpkgs.
As such, make sure to respond to _all_ feedback, either by applying suggested changes or argue in favor of something else or no change.
It wastes everyone time waiting for a couple of days just for the reviewer to remind you to address something they asked for.
### A reviewer requested a bunch of insubstantial changes on my PR
The people involved in Nixpkgs care about code quality because, once in Nixpkgs, it needs to be maintained for many years to come.
It is therefore likely that other people will ask you to do some things in another way or adhere to some standard.
Sometimes however, they also care a bit too much and may ask you to adhere to a personal preference of theirs.
It's not always easy to tell which is which and whether the requests are critically important to merging the PR.
Sometimes another reviewer may also come along with totally different opinions on some points too.
It is convention to mark review comments that are not critical to the PR as nitpicks but this is not always followed.
As the PR author, you should still take a look at these as they will often reveal best practices and unwritten rules that usually have good reasons behind them and you may want to incorporate them into your modus operandi.
Please keep in mind that reviewers almost always mean well here.
Their intent is not to denounce your code, they want your code to be as good as it can be.
Through their experience, they may also take notice of a seemingly insignificant issues that have caused significant burden before.
Sometimes however, they can also get a bit carried away and become too perfectionistic.
If you feel some of the requests are unreasonable, out of scope, or merely a matter of personal preference, try to nicely remind the reviewers that you may not intend this code to be 100% perfect or that you have different taste in some regards and press them on whether they think that these requests are *critical* to the PR's success.
While we do have a set of [official standards for the Nix community](https://github.com/NixOS/rfcs/), we don't have standards for everything and there are often multiple valid ways to achieve the same goal.
Unless there are standards forbidding the patterns used in your code or there are serious technical, maintainability or readability issues with your code, you can insist to keep the code the way you made it and disregard the requests.
Please communicate this clearly though; a simple "I prefer it this way and see no major issue with it" can save you a lot of arguing.
If you are unsure about some change requests, please ask reviewers *why* they requested them.
This will usually reveal how important they deem it to be and will help educate you about standards, best practices, unwritten rules aswell as preferences people have and why.
Some committers may have stronger opinions on some things and therefore (understandably) may not want to merge your PR if you don't follow their requests.
It is totally fine to get yourself a second or third opinion in such a case.
### Committers work on a push-basis
It's possible for you to get a review but nothing happens afterwards, even if you reply to review comments.
A committer not following up on your PR does not necessarily mean they're disinterested or unresponsive, they may have simply forgotten to follow up on it or had some other circumstances preventing them from doing so.
Committers typically handle many other PRs besides yours and it is not realistic for them to keep up with all of them to a degree where they could reasonably remember to follow up on all PRs that they had intended following up upon.
If someone left an approving review on your PR and didn't merge a few days later, the most likely case is that they simply forgot.
Please see it as your responsibility to actively remind reviewers of your open PRs.
The easiest way to do so is to cause them a Github notification.
Github notifies people involved in the PR whenever you add a comment to your PR, push your PR or re-request their review.
Doing any of that will get you people's attention again.
Everyone deserves proper attention, and yes that includes you!
However please be mindful that committers can sadly not always give everyone the attention they deserve.
It may very well be the case that you have to do this every time you need the committer to follow up upon your PR.
Again, this is a community project so please be mindful of people's circumstances here; be nice when requesting reviews again.
It may also be the case that the committer has lost interest or isn't familiar enough with the component you're touching to be comfortable merging your PR.
They will likely not immediately state that fact however, so please ask for clarification and don't hesitate to find yourself another committer to take a look at your PR.
### Nothing helped
If you followed these guidelines but still got no results or if you feel that you have been wronged in some way, please explicitly reach out to the greater community via its communication channels.
The [NixOS Discourse](https://discourse.nixos.org/) is a great place to do this as it has historically been the asynchronous medium with the greatest concentration of committers and other people who are significantly involved in Nixpkgs.
There is a dedicated discourse thread [PRs in distress](https://discourse.nixos.org/t/prs-in-distress/3604) where you can link your PR if everything else fails.
The [Nixpkgs / NixOS contributions Matrix channel](https://matrix.to/#/#dev:nixos.org) is the best synchronous channel with the same qualities.
Please reserve these for cases where you've made a serious effort in trying to get the attention of multiple active committers and provided realistic means for them to assess your PR's quality though.
As mentioned previously, it is unfortunately perfectly normal for a PR to sit around for weeks on end due to the realities of this being a community project.
Please don't blow up situations where progress is happening but is merely not going fast enough for your tastes.
Honking in a traffic jam will not make you go any faster.
See the nixpkgs manual for more details on how to [Review contributions](https://nixos.org/nixpkgs/manual/#chap-reviewing-contributions).

[Nixpkgs](https://github.com/nixos/nixpkgs) is a collection of over
100,000 software packages that can be installed with the
80,000 software packages that can be installed with the
[Nix](https://nixos.org/nix/) package manager. It also implements
[NixOS](https://nixos.org/nixos/), a purely-functional Linux distribution.

Pull Requests. When pull requests are made, our tooling automation bot,
[OfBorg](https://github.com/NixOS/ofborg) will perform various checks
to help ensure expression quality.
The *Nixpkgs maintainers* are people who have assigned themselves to
maintain specific individual packages. We encourage people who care
about a package to assign themselves as a maintainer. When a pull
request is made against a package, OfBorg will notify the appropriate
maintainer(s). The *Nixpkgs committers* are people who have been given
permission to merge.
Most contributions are based on and merged into these branches:
* `master` is the main branch where all small contributions go
* `staging` is branched from master, changes that have a big impact on
Hydra builds go to this branch
* `staging-next` is branched from staging and only fixes to stabilize
and security fixes with a big impact on Hydra builds should be
contributed to this branch. This branch is merged into master when
deemed of sufficiently high quality

# CI support files
This directory contains files to support CI, such as [GitHub Actions](https://github.com/NixOS/nixpkgs/tree/master/.github/workflows) and [Ofborg](https://github.com/nixos/ofborg).
This is in contrast with [`maintainers/scripts`](../maintainers/scripts) which is for human use instead.
## Pinned Nixpkgs
CI may need certain packages from Nixpkgs.
In order to ensure that the needed packages are generally available without building, [`pinned.json`](./pinned.json) contains a pinned Nixpkgs version tested by Hydra.
Run [`update-pinned.sh`](./update-pinned.sh) to update it.
## `ci/nixpkgs-vet.sh BASE_BRANCH [REPOSITORY]`
Runs the [`nixpkgs-vet` tool](https://github.com/NixOS/nixpkgs-vet) on the HEAD commit, closely matching what CI does.
This can't do exactly the same as CI, because CI needs to rely on GitHub's server-side Git history to compute the mergeability of PRs before the check can be started.
In turn, when contributors are running this tool locally, we don't want to have to push commits to test them, and we can also rely on the local Git history to do the mergeability check.
Arguments:
- `BASE_BRANCH`: The base branch to use, e.g. master or release-24.05
- `REPOSITORY`: The repository from which to fetch the base branch.
Defaults to <https://github.com/NixOS/nixpkgs.git>.
# Branch classification
For the purposes of CI, branches in the NixOS/nixpkgs repository are classified as follows:
- **Channel** branches
- `nixos-` or `nixpkgs-` prefix
- Are only updated from `master` or `release-` branches, when hydra passes.
- Otherwise not worked on, Pull Requests are not allowed.
- Long-lived, no deletion, no force push.
- **Primary development** branches
- `release-` prefix and `master`
- Pull Requests required.
- Long-lived, no deletion, no force push.
- **Secondary development** branches
- `staging-` prefix, `haskell-updates` and `python-updates`
- Pull Requests normally required, except when merging development branches into each other.
- Long-lived, no deletion, no force push.
- **Work-In-Progress** branches
- `backport-`, `revert-` and `wip-` prefixes.
- Deprecated: All other branches, not matched by channel/development.
- Pull Requests are optional.
- Short-lived, force push allowed, deleted after merge.
Some branches also have a version component, which is either `unstable` or `YY.MM`.
`ci/supportedBranches.js` is a script imported by CI to classify the base and head branches of a Pull Request.
This classification will then be used to skip certain jobs.

This report is automatically generated by the `check-cherry-picks` CI workflow.
Some of the commits in this PR have not been cherry-picked exactly and require the author's and reviewer's attention.
Please make sure to follow the [backporting guidelines](https://github.com/NixOS/nixpkgs/blob/master/CONTRIBUTING.md#how-to-backport-pull-requests) and cherry-pick with the `-x` flag. This requires changes to go to the unstable branches (`master` / `staging`) first, before backporting them.
Occasionally, it is not possible to cherry-pick exactly the same patch. This most frequently happens when resolving merge conflicts while cherry-picking or when updating minor versions of packages which have already advanced to the next major on unstable. If you need to merge this PR despite the warnings, please [dismiss](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/reviewing-changes-in-pull-requests/dismissing-a-pull-request-review) this review.

# Nixpkgs CI evaluation
The code in this directory is used by the [eval.yml](../../.github/workflows/eval.yml) GitHub Actions workflow to evaluate the majority of Nixpkgs for all PRs, effectively making sure that when the development branches are processed by Hydra, no evaluation failures are encountered.
Furthermore it also allows local evaluation using
```
nix-build ci -A eval.full \
--max-jobs 4 \
--cores 2 \
--arg chunkSize 10000 \
--arg evalSystems '["x86_64-linux" "aarch64-darwin"]'
```
- `--max-jobs`: The maximum number of derivations to run at the same time.
Only each [supported system](../supportedSystems.json) gets a separate derivation, so it doesn't make sense to set this higher than that number.
- `--cores`: The number of cores to use for each job.
Recommended to set this to the amount of cores on your system divided by `--max-jobs`.
- `chunkSize`: The number of attributes that are evaluated simultaneously on a single core.
Lowering this decreases memory usage at the cost of increased evaluation time.
If this is too high, there won't be enough chunks to process them in parallel, and will also increase evaluation time.
- `evalSystems`: The set of systems for which `nixpkgs` should be evaluated.
Defaults to the four official platforms (`x86_64-linux`, `aarch64-linux`, `x86_64-darwin` and `aarch64-darwin`).
A good default is to set `chunkSize` to 10000, which leads to about 3.6GB max memory usage per core, so suitable for fully utilising machines with 4 cores and 16GB memory, 8 cores and 32GB memory or 16 cores and 64GB memory.
Note that 16GB memory is the recommended minimum, while with less than 8GB memory evaluation time suffers greatly.

# Contributing to the Nixpkgs reference manual
This directory houses the sources files for the Nixpkgs reference manual.
# Nixpkgs/doc
> [!IMPORTANT]
> We are actively restructuring our documentation to follow the [Diátaxis framework](https://diataxis.fr/)
>
> Going forward, this directory should **only** contain [reference documentation](https://nix.dev/contributing/documentation/diataxis#reference).
> For tutorials, guides and explanations, contribute to <https://nix.dev/> instead.
>
> We are actively working to generate **all** reference documentation from the [doc-comments](https://github.com/NixOS/rfcs/blob/master/rfcs/0145-doc-strings.md) present in code.
> This also provides the benefit of using `:doc` in the `nix repl` to view reference documentation locally on the fly.
This directory houses the sources files for the Nixpkgs manual.
For documentation only relevant for contributors, use Markdown files next to the source and regular code comments.
You can find the [rendered documentation for Nixpkgs `unstable` on nixos.org](https://nixos.org/manual/nixpkgs/unstable/).
> [!TIP]
> Feedback for improving support for parsing and rendering doc-comments is highly appreciated.
> [Open an issue](https://github.com/NixOS/nixpkgs/issues/new?labels=6.topic%3A+documentation&title=Doc%3A+) to request bugfixes or new features.
[Docs for Nixpkgs stable](https://nixos.org/manual/nixpkgs/stable/) are also available.
Rendered documentation:
- [Unstable (from master)](https://nixos.org/manual/nixpkgs/unstable/)
- [Stable (from latest release)](https://nixos.org/manual/nixpkgs/stable/)
If you want to contribute to the documentation, [here's how to do it](https://nixos.org/manual/nixpkgs/unstable/#chap-contributing).
The rendering tool is [nixos-render-docs](../pkgs/tools/nix/nixos-render-docs/src/nixos_render_docs), sometimes abbreviated `nrd`.
## Contributing to this documentation
You can quickly check your edits with `nix-build`:
```ShellSession
$ cd /path/to/nixpkgs
$ nix-build doc
```
If the build succeeds, the manual will be in `./result/share/doc/nixpkgs/manual.html`.
### devmode
The shell in the manual source directory makes available a command, `devmode`.
It is a daemon, that:
1. watches the manual's source for changes and when they occur — rebuilds
2. HTTP serves the manual, injecting a script that triggers reload on changes
3. opens the manual in the default browser
## Syntax
As per [RFC 0072](https://github.com/NixOS/rfcs/pull/72), all new documentation content should be written in [CommonMark](https://commonmark.org/) Markdown dialect.
Additional syntax extensions are available, all of which can be used in NixOS option documentation. The following extensions are currently used:
#### Tables
Tables, using the [GitHub-flavored Markdown syntax](https://github.github.com/gfm/#tables-extension-).
#### Anchors
Explicitly defined **anchors** on headings, to allow linking to sections. These should be always used, to ensure the anchors can be linked even when the heading text changes, and to prevent conflicts between [automatically assigned identifiers](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/auto_identifiers.md).
It uses the widely compatible [header attributes](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/attributes.md) syntax:
```markdown
## Syntax {#sec-contributing-markup}
```
> [!Note]
> NixOS option documentation does not support headings in general.
#### Inline Anchors
Allow linking arbitrary place in the text (e.g. individual list items, sentences…).
They are defined using a hybrid of the link syntax with the attributes syntax known from headings, called [bracketed spans](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/bracketed_spans.md):
```markdown
- []{#ssec-gnome-hooks-glib} `glib` setup hook will populate `GSETTINGS_SCHEMAS_PATH` and then `wrapGApps*` hook will prepend it to `XDG_DATA_DIRS`.
```
#### Automatic links
If you **omit a link text** for a link pointing to a section, the text will be substituted automatically. For example `[](#chap-contributing)`.
This syntax is taken from [MyST](https://myst-parser.readthedocs.io/en/latest/using/syntax.html#targets-and-cross-referencing).
#### HTML
Inlining HTML is not allowed. Parts of the documentation gets rendered to various non-HTML formats, such as man pages in the case of NixOS manual.
#### Roles
If you want to link to a man page, you can use `` {manpage}`nix.conf(5)` ``. The references will turn into links when a mapping exists in [`doc/manpage-urls.json`](./manpage-urls.json).
A few markups for other kinds of literals are also available:
- `` {command}`rm -rfi` ``
- `` {env}`XDG_DATA_DIRS` ``
- `` {file}`/etc/passwd` ``
- `` {option}`networking.useDHCP` ``
- `` {var}`/etc/passwd` ``
These literal kinds are used mostly in NixOS option documentation.
This syntax is taken from [MyST](https://myst-parser.readthedocs.io/en/latest/syntax/syntax.html#roles-an-in-line-extension-point). Though, the feature originates from [reStructuredText](https://www.sphinx-doc.org/en/master/usage/restructuredtext/roles.html#role-manpage) with slightly different syntax.
#### Admonitions
Set off from the text to bring attention to something.
It uses pandocs [fenced `div`s syntax](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/fenced_divs.md):
```markdown
::: {.warning}
This is a warning
:::
```
The following are supported:
- `caution`
- `important`
- `note`
- `tip`
- `warning`
- `example`
Example admonitions require a title to work.
If you don't provide one, the manual won't be built.
```markdown
::: {.example #ex-showing-an-example}
# Title for this example
Text for the example.
:::
```
#### [Definition lists](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/definition_lists.md)
For defining a group of terms:
```markdown
pear
: green or yellow bulbous fruit
watermelon
: green fruit with red flesh
```
## Commit conventions
- Make sure you read about the [commit conventions](../CONTRIBUTING.md#commit-conventions) common to Nixpkgs as a whole.
- If creating a commit purely for documentation changes, format the commit message in the following way:
```
doc: (documentation summary)
(Motivation for change, relevant links, additional information.)
```
Examples:
* doc: update the kernel config documentation to use `nix-shell`
* doc: add information about `nix-update-script`
Closes #216321.
- If the commit contains more than just documentation changes, follow the commit message format relevant for the rest of the changes.
## Documentation conventions
In an effort to keep the Nixpkgs manual in a consistent style, please follow the conventions below, unless they prevent you from properly documenting something.
In that case, please open an issue about the particular documentation convention and tag it with a "needs: documentation" label.
When needed, each convention explain why it exists, so you can make a decision whether to follow it or not based on your particular case.
Note that these conventions are about the **structure** of the manual (and its source files), not about the content that goes in it.
You, as the writer of documentation, are still in charge of its content.
### One sentence per line
Put each sentence in its own line.
This makes reviews and suggestions much easier, since GitHub's review system is based on lines.
It also helps identifying long sentences at a glance.
### Callouts and examples
Use the [admonition syntax](#admonitions) for callouts and examples.
### Provide self-contained examples
Provide at least one example per function, and make examples self-contained.
This is easier to understand for beginners.
It also helps with testing that it actually works especially once we introduce automation.
Example code should be such that it can be passed to `pkgs.callPackage`.
Instead of something like:
```nix
pkgs.dockerTools.buildLayeredImage {
name = "hello";
contents = [ pkgs.hello ];
}
```
Write something like:
```nix
{ dockerTools, hello }:
dockerTools.buildLayeredImage {
name = "hello";
contents = [ hello ];
}
```
### REPLs
When showing inputs/outputs of any [REPL](https://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_loop), such as a shell or the Nix REPL, use a format as you'd see in the REPL, while trying to visually separate inputs from outputs.
This means that for a shell, you should use a format like the following:
```shell
$ nix-build -A hello '<nixpkgs>' \
--option require-sigs false \
--option trusted-substituters file:///tmp/hello-cache \
--option substituters file:///tmp/hello-cache
/nix/store/zhl06z4lrfrkw5rp0hnjjfrgsclzvxpm-hello-2.12.1
```
Note how the input is preceded by `$` on the first line and indented on subsequent lines, and how the output is provided as you'd see on the shell.
For the Nix REPL, you should use a format like the following:
```shell
nix-repl> builtins.attrNames { a = 1; b = 2; }
[ "a" "b" ]
```
Note how the input is preceded by `nix-repl>` and the output is provided as you'd see on the Nix REPL.
### Headings for inputs, outputs and examples
When documenting functions or anything that has inputs/outputs and example usage, use nested headings to clearly separate inputs, outputs, and examples.
Keep examples as the last nested heading, and link to the examples wherever applicable in the documentation.
The purpose of this convention is to provide a familiar structure for navigating the manual, so any reader can expect to find content related to inputs in an "inputs" heading, examples in an "examples" heading, and so on.
An example:
```
## buildImage
Some explanation about the function here.
Describe a particular scenario, and point to [](#ex-dockerTools-buildImage), which is an example demonstrating it.
### Inputs
Documentation for the inputs of `buildImage`.
Perhaps even point to [](#ex-dockerTools-buildImage) again when talking about something specifically linked to it.
### Passthru outputs
Documentation for any passthru outputs of `buildImage`.
### Examples
Note that this is the last nested heading in the `buildImage` section.
:::{.example #ex-dockerTools-buildImage}
# Using `buildImage`
Example of how to use `buildImage` goes here.
:::
```
### Function arguments
Use [definition lists](#definition-lists) to document function arguments, and the attributes of such arguments as well as their [types](https://nixos.org/manual/nix/stable/language/values).
For example:
```markdown
# pkgs.coolFunction {#pkgs.coolFunction}
`pkgs.coolFunction` *`name`* *`config`*
Description of what `callPackage` does.
## Inputs {#pkgs-coolFunction-inputs}
If something's special about `coolFunction`'s general argument handling, you can say so here.
Otherwise, just describe the single argument or start the arguments' definition list without introduction.
*`name`* (String)
: The name of the resulting image.
*`config`* (Attribute set)
: Introduce the parameter. Maybe you have a test to make sure `{ }` is a sensible default; then you can say: these attributes are optional; `{ }` is a valid argument.
`outputHash` (String; _optional_)
: A brief explanation including when and when not to pass this attribute.
: _Default:_ the output path's hash.
```
Checklist:
- Start with a synopsis, to show the order of positional arguments.
- Metavariables are in emphasized code spans: ``` *`arg1`* ```. Metavariables are placeholders where users may write arbitrary expressions. This includes positional arguments.
- Attribute names are regular code spans: ``` `attr1` ```. These identifiers can _not_ be picked freely by users, so they are _not_ metavariables.
- _optional_ attributes have a _`Default:`_ if it's easily described as a value.
- _optional_ attributes have a _`Default behavior:`_ if it's not easily described using a value.
- Nix types aren't in code spans, because they are not code
- Nix types are capitalized, to distinguish them from the camelCase Module System types, which _are_ code and behave like functions.
#### Examples
To define a referenceable figure use the following fencing:
```markdown
:::{.example #an-attribute-set-example}
# An attribute set example
You can add text before
```nix
{ a = 1; b = 2;}
```
and after code fencing
:::
```
Defining examples through the `example` fencing class adds them to a "List of Examples" section after the Table of Contents.
Though this is not shown in the rendered documentation on nixos.org.
#### Figures
To define a referenceable figure use the following fencing:
```markdown
::: {.figure #nixos-logo}
# NixOS Logo
![NixOS logo](./nixos_logo.png)
:::
```
Defining figures through the `figure` fencing class adds them to a `List of Figures` after the `Table of Contents`.
Though this is not shown in the rendered documentation on nixos.org.
#### Footnotes
To add a foonote explanation, use the following syntax:
```markdown
Sometimes it's better to add context [^context] in a footnote.
[^context]: This explanation will be rendered at the end of the chapter.
```
#### Inline comments
Inline comments are supported with following syntax:
```markdown
<!-- This is an inline comment -->
```
The comments will not be rendered in the rendered HTML.
#### Link reference definitions
Links can reference a label, for example, to make the link target reusable:
```markdown
::: {.note}
Reference links can also be used to [shorten URLs][url-id] and keep the markdown readable.
:::
[url-id]: https://github.com/NixOS/nixpkgs/blob/19d4f7dc485f74109bd66ef74231285ff797a823/doc/README.md
```
This syntax is taken from [CommonMark](https://spec.commonmark.org/0.30/#link-reference-definitions).
#### Typographic replacements
Typographic replacements are enabled. Check the [list of possible replacement patterns check](https://github.com/executablebooks/markdown-it-py/blob/3613e8016ecafe21709471ee0032a90a4157c2d1/markdown_it/rules_core/replacements.py#L1-L15).
## Getting help
If you need documentation-specific help or reviews, ping [@NixOS/documentation-team](https://github.com/orgs/nixos/teams/documentation-team) on your pull request.
If you're only getting started with Nix, go to [nixos.org/learn](https://nixos.org/learn).

# Build helpers {#part-builders}
A build helper is a function that produces derivations.
:::{.warning}
This is not to be confused with the [`builder` argument of the Nix `derivation` primitive](https://nixos.org/manual/nix/unstable/language/derivations.html), which refers to the executable that produces the build result, or [remote builder](https://nixos.org/manual/nix/stable/advanced-topics/distributed-builds.html), which refers to a remote machine that could run such an executable.
:::
Such a function is usually designed to abstract over a typical workflow for a given programming language or framework.
This allows declaring a build recipe by setting a limited number of options relevant to the particular use case instead of using the `derivation` function directly.
[`stdenv.mkDerivation`](#part-stdenv) is the most widely used build helper, and serves as a basis for many others.
In addition, it offers various options to customize parts of the builds.
There is no uniform interface for build helpers.
[Trivial build helpers](#chap-trivial-builders) and [fetchers](#chap-pkgs-fetchers) have various input types for convenience.
[Language- or framework-specific build helpers](#chap-language-support) usually follow the style of `stdenv.mkDerivation`, which accepts an attribute set or a fixed-point function taking an attribute set.

# Development Shell helpers {#chap-devShellTools}
The `nix-shell` command has popularized the concept of transient shell environments for development or testing purposes.
<!--
We should try to document the product, not its development process in the Nixpkgs reference manual,
but *something* needs to be said to provide context for this library.
This is the most future proof sentence I could come up with while Nix itself does yet make use of this.
Relevant is the current status of the devShell attribute "project": https://github.com/NixOS/nix/issues/7501
-->
However, `nix-shell` is not the only way to create such environments, and even `nix-shell` itself can indirectly benefit from this library.
This library provides a set of functions that help create such environments.
## `devShellTools.valueToString` {#sec-devShellTools-valueToString}
Converts Nix values to strings in the way the [`derivation` built-in function](https://nix.dev/manual/nix/2.23/language/derivations) does.
:::{.example}
## `valueToString` usage examples
```nix
devShellTools.valueToString (builtins.toFile "foo" "bar")
# => "/nix/store/...-foo"
```
```nix
devShellTools.valueToString false
# => ""
```
:::
## `devShellTools.unstructuredDerivationInputEnv` {#sec-devShellTools-unstructuredDerivationInputEnv}
Convert a set of derivation attributes (as would be passed to [`derivation`]) to a set of environment variables that can be used in a shell script.
This function does not support `__structuredAttrs`, but does support `passAsFile`.
:::{.example}
## `unstructuredDerivationInputEnv` usage example
```nix
devShellTools.unstructuredDerivationInputEnv {
drvAttrs = {
name = "foo";
buildInputs = [
hello
figlet
];
builder = bash;
args = [
"-c"
"${./builder.sh}"
];
};
}
# => {
# name = "foo";
# buildInputs = "/nix/store/...-hello /nix/store/...-figlet";
# builder = "/nix/store/...-bash";
# }
```
Note that `args` is not included, because Nix does not added it to the builder process environment.
:::
## `devShellTools.derivationOutputEnv` {#sec-devShellTools-derivationOutputEnv}
Takes the relevant parts of a derivation and returns a set of environment variables, that would be present in the derivation.
:::{.example}
## `derivationOutputEnv` usage example
```nix
let
pkg = hello;
in
devShellTools.derivationOutputEnv {
outputList = pkg.outputs;

# Fetchers {#chap-pkgs-fetchers}
Building software with Nix often requires downloading source code and other files from the internet.
To this end, we use functions that we call _fetchers_, which obtain remote sources via various protocols and services.
Nix provides built-in fetchers such as [`builtins.fetchTarball`](https://nixos.org/manual/nix/stable/language/builtins.html#builtins-fetchTarball).
Nixpkgs provides its own fetchers, which work differently:
- A built-in fetcher will download and cache files at evaluation time and produce a [store path](https://nixos.org/manual/nix/stable/glossary#gloss-store-path).
A Nixpkgs fetcher will create a ([fixed-output](https://nixos.org/manual/nix/stable/glossary#gloss-fixed-output-derivation)) [derivation](https://nixos.org/manual/nix/stable/glossary#gloss-derivation), and files are downloaded at build time.
- Built-in fetchers will invalidate their cache after [`tarball-ttl`](https://nixos.org/manual/nix/stable/command-ref/conf-file#conf-tarball-ttl) expires, and will require network activity to check if the cache entry is up to date.
Nixpkgs fetchers only re-download if the specified hash changes or the store object is not available.
- Built-in fetchers do not use [substituters](https://nixos.org/manual/nix/stable/command-ref/conf-file#conf-substituters).
Derivations produced by Nixpkgs fetchers will use any configured binary cache transparently.
This significantly reduces the time needed to evaluate Nixpkgs, and allows [Hydra](https://nixos.org/hydra) to retain and re-distribute sources used by Nixpkgs in the [public binary cache](https://cache.nixos.org).
For these reasons, Nix's built-in fetchers are not allowed in Nixpkgs.
The following table summarises the differences:
| Fetchers | Download | Output | Cache | Re-download when |
|-|-|-|-|-|
| `builtins.fetch*` | evaluation time | store path | `/nix/store`, `~/.cache/nix` | `tarball-ttl` expires, cache miss in `~/.cache/nix`, output store object not in local store |
| `pkgs.fetch*` | build time | derivation | `/nix/store`, substituters | output store object not available |
:::{.tip}
`pkgs.fetchFrom*` helpers retrieve _snapshots_ of version-controlled sources, as opposed to the entire version history, which is more efficient.
`pkgs.fetchgit` by default also has the same behaviour, but can be changed through specific attributes given to it.
:::
## Caveats {#chap-pkgs-fetchers-caveats}
Because Nixpkgs fetchers are fixed-output derivations, an [output hash](https://nixos.org/manual/nix/stable/language/advanced-attributes#adv-attr-outputHash) has to be specified, usually indirectly through a `hash` attribute.
This hash refers to the derivation output, which can be different from the remote source itself!
This has the following implications that you should be aware of:
- Use Nix (or Nix-aware) tooling to produce the output hash.
- When changing any fetcher parameters, always update the output hash.
Use one of the methods from [](#sec-pkgs-fetchers-updating-source-hashes).
Otherwise, existing store objects that match the output hash will be re-used rather than fetching new content.
:::{.note}
A similar problem arises while testing changes to a fetcher's implementation.
If the output of the derivation already exists in the Nix store, test failures can go undetected.
The [`invalidateFetcherByDrvHash`](#tester-invalidateFetcherByDrvHash) function helps prevent reusing cached derivations.
:::
## Updating source hashes {#sec-pkgs-fetchers-updating-source-hashes}
There are several ways to obtain the hash corresponding to a remote source.
Unless you understand how the fetcher you're using calculates the hash from the downloaded contents, you should use [the fake hash method](#sec-pkgs-fetchers-updating-source-hashes-fakehash-method).
1. []{#sec-pkgs-fetchers-updating-source-hashes-fakehash-method} The fake hash method: In your package recipe, set the hash to one of
- `""`
- `lib.fakeHash`
- `lib.fakeSha256`
- `lib.fakeSha512`
Attempt to build, extract the calculated hashes from error messages, and put them into the recipe.
:::{.warning}
You must use one of these four fake hashes and not some arbitrarily-chosen hash.
See [](#sec-pkgs-fetchers-secure-hashes) for details.
:::
:::{.example #ex-fetchers-update-fod-hash}
# Update source hash with the fake hash method
Consider the following recipe that produces a plain file:
```nix
{ fetchurl }:
fetchurl {
url = "https://raw.githubusercontent.com/NixOS/nixpkgs/23.05/.version";
hash = "sha256-ZHl1emidXVojm83LCVrwULpwIzKE/mYwfztVkvpruOM=";
}
```
A common mistake is to update a fetcher parameter, such as `url`, without updating the hash:
```nix
{ fetchurl }:
fetchurl {
url = "https://raw.githubusercontent.com/NixOS/nixpkgs/23.11/.version";
hash = "sha256-ZHl1emidXVojm83LCVrwULpwIzKE/mYwfztVkvpruOM=";
}
```
**This will produce the same output as before!**
Set the hash to an empty string:
```nix
{ fetchurl }:
fetchurl {
url = "https://raw.githubusercontent.com/NixOS/nixpkgs/23.11/.version";
hash = "";
}
```
When building the package, use the error message to determine the correct hash:
```shell
$ nix-build
(some output removed for clarity)
error: hash mismatch in fixed-output derivation '/nix/store/7yynn53jpc93l76z9zdjj4xdxgynawcw-version.drv':

Prefetch the source with [`nix-prefetch-<type> <URL>`](https://search.nixos.org/packages?buckets={%22package_attr_set%22%3A[%22No%20package%20set%22]%2C%22package_license_set%22%3A[]%2C%22package_maintainers_set%22%3A[]%2C%22package_platforms%22%3A[]}&query=nix-prefetch), where `<type>` is one of
- `url`
- `git`
- `hg`
- `cvs`
- `bzr`
- `svn`
The hash is printed to stdout.
3. Prefetch by package source (with `nix-prefetch-url '<nixpkgs>' -A <package>.src`, where `<package>` is package attribute name).
The hash is printed to stdout.
This works well when you've upgraded the existing package version and want to find out new hash, but is useless if the package can't be accessed by attribute or the package has multiple sources (`.srcs`, architecture-dependent sources, etc).
4. Upstream hash: use it when upstream provides `sha256` or `sha512`.
Don't use it when upstream provides `md5`, compute `sha256` instead.
A little nuance is that `nix-prefetch-*` tools produce hashes with the `nix32` encoding (a Nix-specific base32 adaptation), but upstream usually provides hexadecimal (`base16`) encoding.
Fetchers understand both formats.
Nixpkgs does not standardise on any one format.
You can convert between hash formats with [`nix-hash`](https://nixos.org/manual/nix/stable/command-ref/nix-hash).
5. Extract the hash from a local source archive with `sha256sum`.
Use `nix-prefetch-url file:///path/to/archive` if you want the custom Nix `base32` hash.
## Obtaining hashes securely {#sec-pkgs-fetchers-secure-hashes}
It's always a good idea to avoid Man-in-the-Middle (MITM) attacks when downloading source contents.
Otherwise, you could unknowingly download malware instead of the intended source, and instead of the actual source hash, you'll end up using the hash of malware.
Here are security considerations for this scenario:
- `http://` URLs are not secure to prefetch hashes.
- Upstream hashes should be obtained via a secure protocol.
- `https://` URLs give you more protections when using `nix-prefetch-*` or for upstream hashes.
- `https://` URLs are secure when using the [fake hash method](#sec-pkgs-fetchers-updating-source-hashes-fakehash-method) *only if* you use one of the listed fake hashes.
If you use any other hash, the download will be exposed to MITM attacks even if you use HTTPS URLs.
In more concrete terms, if you use any other hash, the [`--insecure` flag](https://curl.se/docs/manpage.html#-k) will be passed to the underlying call to `curl` when downloading content.
## Proxy usage {#sec-pkgs-fetchers-proxy}
Nixpkgs fetchers can make use of a http(s) proxy. Each fetcher will automatically inherit proxy-related environment variables (`http_proxy`, `https_proxy`, etc) via [impureEnvVars](https://nixos.org/manual/nix/stable/language/advanced-attributes#adv-attr-impureEnvVars).
The environment variable `NIX_SSL_CERT_FILE` is also inherited in fetchers, and can be used to provide a custom certificate bundle to fetchers. This is usually required for a https proxy to work without certificate validation errors.
[]{#fetchurl}
## `fetchurl` {#sec-pkgs-fetchers-fetchurl}
`fetchurl` returns a [fixed-output derivation](https://nixos.org/manual/nix/stable/glossary.html#gloss-fixed-output-derivation) which downloads content from a given URL and stores the unaltered contents within the Nix store.
It uses {manpage}`curl(1)` internally, and allows its behaviour to be modified by specifying a few attributes in the argument to `fetchurl` (see the documentation for attributes `curlOpts`, `curlOptsList`, and `netrcPhase`).
The resulting [store path](https://nixos.org/manual/nix/stable/store/store-path) is determined by the hash given to `fetchurl`, and also the `name` (or `pname` and `version`) values.
If neither `name` nor `pname` and `version` are specified when calling `fetchurl`, it will default to using the [basename](https://nixos.org/manual/nix/stable/language/builtins.html#builtins-baseNameOf) of `url` or the first element of `urls`.
If `pname` and `version` are specified, `fetchurl` will use those values and will ignore `name`, even if it is also specified.
### Inputs {#sec-pkgs-fetchers-fetchurl-inputs}
`fetchurl` requires an attribute set with the following attributes:
`url` (String; _optional_)
: The URL to download from.
:::{.note}
Either `url` or `urls` must be specified, but not both.
:::
All URLs of the format [specified here](https://curl.se/docs/url-syntax.html#rfc-3986-plus) are supported.
_Default value:_ `""`.
`urls` (List of String; _optional_)
: A list of URLs, specifying download locations for the same content.
Each URL will be tried in order until one of them succeeds with some content or all of them fail.
See [](#ex-fetchers-fetchurl-nixpkgs-version-multiple-urls) to understand how this attribute affects the behaviour of `fetchurl`.
:::{.note}
Either `url` or `urls` must be specified, but not both.
:::
_Default value:_ `[]`.
`hash` (String; _optional_)
: Hash of the derivation output of `fetchurl`, following the format for integrity metadata as defined by [SRI](https://www.w3.org/TR/SRI/).
For more information, see [](#chap-pkgs-fetchers-caveats).
:::{.note}
It is recommended that you use the `hash` attribute instead of the other hash-specific attributes that exist for backwards compatibility.
If `hash` is not specified, you must specify `outputHash` and `outputHashAlgo`, or one of `sha512`, `sha256`, or `sha1`.
:::
_Default value:_ `""`.
`outputHash` (String; _optional_)
: Hash of the derivation output of `fetchurl` in the format expected by Nix.
See [the documentation on the Nix manual](https://nixos.org/manual/nix/stable/language/advanced-attributes.html#adv-attr-outputHash) for more information about its format.
:::{.note}
It is recommended that you use the `hash` attribute instead.
If `outputHash` is specified, you must also specify `outputHashAlgo`.
:::
_Default value:_ `""`.
`outputHashAlgo` (String; _optional_)
: Algorithm used to generate the value specified in `outputHash`.
See [the documentation on the Nix manual](https://nixos.org/manual/nix/stable/language/advanced-attributes.html#adv-attr-outputHashAlgo) for more information about the values it supports.
:::{.note}
It is recommended that you use the `hash` attribute instead.
The value specified in `outputHashAlgo` will be ignored if `outputHash` isn't also specified.
:::
_Default value:_ `""`.
`sha1` (String; _optional_)
: SHA-1 hash of the derivation output of `fetchurl` in the format expected by Nix.
See [the documentation on the Nix manual](https://nixos.org/manual/nix/stable/language/advanced-attributes.html#adv-attr-outputHash) for more information about its format.
:::{.note}
It is recommended that you use the `hash` attribute instead.
:::
_Default value:_ `""`.
`sha256` (String; _optional_)
: SHA-256 hash of the derivation output of `fetchurl` in the format expected by Nix.
See [the documentation on the Nix manual](https://nixos.org/manual/nix/stable/language/advanced-attributes.html#adv-attr-outputHash) for more information about its format.
:::{.note}
It is recommended that you use the `hash` attribute instead.
:::
_Default value:_ `""`.
`sha512` (String; _optional_)
: SHA-512 hash of the derivation output of `fetchurl` in the format expected by Nix.
See [the documentation on the Nix manual](https://nixos.org/manual/nix/stable/language/advanced-attributes.html#adv-attr-outputHash) for more information about its format.
:::{.note}
It is recommended that you use the `hash` attribute instead.
:::
_Default value:_ `""`.
`name` (String; _optional_)
: The symbolic name of the downloaded file when saved in the Nix store.
See [the `fetchurl` overview](#sec-pkgs-fetchers-fetchurl) for details on how the name of the file is decided.
_Default value:_ `""`.
`pname` (String; _optional_)
: A base name, which will be combined with `version` to form the symbolic name of the downloaded file when saved in the Nix store.
See [the `fetchurl` overview](#sec-pkgs-fetchers-fetchurl) for details on how the name of the file is decided.
:::{.note}
If `pname` is specified, you must also specify `version`, otherwise `fetchurl` will ignore the value of `pname`.
:::
_Default value:_ `""`.
`version` (String; _optional_)
: A version, which will be combined with `pname` to form the symbolic name of the downloaded file when saved in the Nix store.
See [the `fetchurl` overview](#sec-pkgs-fetchers-fetchurl) for details on how the name of the file is decided.
_Default value:_ `""`.
`recursiveHash` (Boolean; _optional_) []{#sec-pkgs-fetchers-fetchurl-inputs-recursiveHash}
: If set to `true`, will signal to Nix that the hash given to `fetchurl` was calculated using the `"recursive"` mode.
See [the documentation on the Nix manual](https://nixos.org/manual/nix/stable/language/advanced-attributes.html#adv-attr-outputHashMode) for more information about the existing modes.
By default, `fetchurl` uses `"recursive"` mode when the `executable` attribute is set to `true`, so you don't need to specify `recursiveHash` in this case.
_Default value:_ `false`.
`executable` (Boolean; _optional_)
: If `true`, sets the executable bit on the downloaded file.
_Default value_: `false`.
`downloadToTemp` (Boolean; _optional_) []{#sec-pkgs-fetchers-fetchurl-inputs-downloadToTemp}
: If `true`, saves the downloaded file to a temporary location instead of the expected Nix store location.
This is useful when used in conjunction with `postFetch` attribute, otherwise `fetchurl` will not produce any meaningful output.
The location of the downloaded file will be set in the `$downloadedFile` variable, which should be used by the script in the `postFetch` attribute.
See [](#ex-fetchers-fetchurl-nixpkgs-version-postfetch) to understand how to work with this attribute.
_Default value:_ `false`.
`postFetch` (String; _optional_)
: Script executed after the file has been downloaded successfully, and before `fetchurl` finishes running.
Useful for post-processing, to check or transform the file in some way.
See [](#ex-fetchers-fetchurl-nixpkgs-version-postfetch) to understand how to work with this attribute.
_Default value:_ `""`.
`netrcPhase` (String or Null; _optional_)
: Script executed to create a {manpage}`netrc(5)` file to be used with {manpage}`curl(1)`.
The script should create the `netrc` file (note that it does not begin with a ".") in the directory it's currently running in (`$PWD`).
The script is executed during the setup done by `fetchurl` before it runs any of its code to download the specified content.
:::{.note}
If specified, `fetchurl` will automatically alter its invocation of {manpage}`curl(1)` to use the `netrc` file, so you don't need to add anything to `curlOpts` or `curlOptsList`.
:::
:::{.caution}
Since `netrcPhase` needs to be specified in your source Nix code, any secrets that you put directly in it will be world-readable by design (both in your source code, and when the derivation gets created in the Nix store).
If you want to avoid this behaviour, see the documentation of `netrcImpureEnvVars` for an alternative way of dealing with these secrets.
:::
_Default value_: `null`.
`netrcImpureEnvVars` (List of String; _optional_)
: If specified, `fetchurl` will add these environment variable names to the list of [impure environment variables](https://nixos.org/manual/nix/stable/language/advanced-attributes.html#adv-attr-impureEnvVars), which will be passed from the environment of the calling user to the builder running the `fetchurl` code.
This is useful when used with `netrcPhase` to hide any secrets that are used in it, because the script in `netrcPhase` only needs to reference the environment variables with the secrets in them instead.
However, note that these are called _impure_ variables for a reason:
the environment that starts the build needs to have these variables declared for everything to work properly, which means that additional setup is required outside what Nix controls.
_Default value:_ `[]`.
`curlOpts` (String; _optional_)
: If specified, this value will be appended to the invocation of {manpage}`curl(1)` when downloading the URL(s) given to `fetchurl`.
Multiple arguments can be separated by spaces normally, but values with whitespaces will be interpreted as multiple arguments (instead of a single value), even if the value is escaped.
See `curlOptsList` for a way to pass values with whitespaces in them.
_Default value:_ `""`.
`curlOptsList` (List of String; _optional_)
: If specified, each element of this list will be passed as an argument to the invocation of {manpage}`curl(1)` when downloading the URL(s) given to `fetchurl`.
This allows passing values that contain spaces, with no escaping needed.
_Default value:_ `[]`.
`showURLs` (Boolean; _optional_)
: If set to `true`, this will stop `fetchurl` from downloading anything at all.
Instead, it will output a list of all the URLs it would've used to download the content (after resolving `mirror://` URLs, for example).
This is useful for debugging.
_Default value:_ `false`.
`meta` (Attribute Set; _optional_)
: Specifies any [meta-attributes](#chap-meta) for the derivation returned by `fetchurl`.
_Default value:_ `{}`.
`passthru` (Attribute Set; _optional_)
: Specifies any extra [`passthru`](#chap-passthru) attributes for the derivation returned by `fetchurl`.
Note that `fetchurl` defines [`passthru` attributes of its own](#ssec-pkgs-fetchers-fetchurl-passthru-outputs).
Attributes specified in `passthru` can override the default attributes returned by `fetchurl`.
_Default value:_ `{}`.
`preferLocalBuild` (Boolean; _optional_)
: This is the same attribute as [defined in the Nix manual](https://nixos.org/manual/nix/stable/language/advanced-attributes.html#adv-attr-preferLocalBuild).
It is `true` by default because making a remote machine download the content just duplicates network traffic (since the local machine might download the results from the derivation anyway), but this could be useful in cases where network access is restricted on local machines.
_Default value:_ `true`.
`nativeBuildInputs` (List of Attribute Set; _optional_)
: Additional packages needed to download the content.
This is useful if you need extra packages for `postFetch` or `netrcPhase`, for example.
Has the same semantics as in [](#var-stdenv-nativeBuildInputs).
See [](#ex-fetchers-fetchurl-nixpkgs-version-postfetch) to understand how this can be used with `postFetch`.
_Default value:_ `[]`.
### Passthru outputs {#ssec-pkgs-fetchers-fetchurl-passthru-outputs}
`fetchurl` also defines its own [`passthru`](#chap-passthru) attributes:
`url` (String)
: The same `url` attribute passed in the argument to `fetchurl`.
### Examples {#ssec-pkgs-fetchers-fetchurl-examples}
:::{.example #ex-fetchers-fetchurl-nixpkgs-version}
# Using `fetchurl` to download a file
The following package downloads a small file from a URL and shows the most common way to use `fetchurl`:
```nix
{ fetchurl }:
fetchurl {
url = "https://raw.githubusercontent.com/NixOS/nixpkgs/23.11/.version";
hash = "sha256-BZqI7r0MNP29yGH5+yW2tjU9OOpOCEvwWKrWCv5CQ0I=";
}
```
After building the package, the file will be downloaded and place into the Nix store:
```shell
$ nix-build
(output removed for clarity)
/nix/store/4g9y3x851wqrvim4zcz5x2v3zivmsq8n-version
$ cat /nix/store/4g9y3x851wqrvim4zcz5x2v3zivmsq8n-version
23.11
```
:::
:::{.example #ex-fetchers-fetchurl-nixpkgs-version-multiple-urls}
# Using `fetchurl` to download a file with multiple possible URLs
The following package adapts [](#ex-fetchers-fetchurl-nixpkgs-version) to use multiple URLs.
The first URL was crafted to intentionally return an error to illustrate how `fetchurl` will try multiple URLs until it finds one that works (or all URLs fail).
```nix
{ fetchurl }:
fetchurl {
urls = [
"https://raw.githubusercontent.com/NixOS/nixpkgs/23.11/does-not-exist"
"https://raw.githubusercontent.com/NixOS/nixpkgs/23.11/.version"
];
hash = "sha256-BZqI7r0MNP29yGH5+yW2tjU9OOpOCEvwWKrWCv5CQ0I=";
}
```
After building the package, both URLs will be used to download the file:
```shell
$ nix-build
(some output removed for clarity)
trying https://raw.githubusercontent.com/NixOS/nixpkgs/23.11/does-not-exist
(some output removed for clarity)
curl: (22) The requested URL returned error: 404
trying https://raw.githubusercontent.com/NixOS/nixpkgs/23.11/.version
(some output removed for clarity)
/nix/store/n9asny31z32q7sdw6a8r1gllrsfy53kl-does-not-exist
$ cat /nix/store/n9asny31z32q7sdw6a8r1gllrsfy53kl-does-not-exist
23.11
```
However, note that the name of the file was derived from the first URL (this is further explained in [the `fetchurl` overview](#sec-pkgs-fetchers-fetchurl)).
To ensure the result will have the same name regardless of which URLs are used, we can modify the package:
```nix
{ fetchurl }:
fetchurl {
name = "nixpkgs-version";
urls = [
"https://raw.githubusercontent.com/NixOS/nixpkgs/23.11/does-not-exist"
"https://raw.githubusercontent.com/NixOS/nixpkgs/23.11/.version"
];
hash = "sha256-BZqI7r0MNP29yGH5+yW2tjU9OOpOCEvwWKrWCv5CQ0I=";
}
```
After building the package, the result will have the name we specified:
```shell
$ nix-build
(output removed for clarity)
/nix/store/zczb6wl3al6jm9sm5h3pr6nqn0i5ji9z-nixpkgs-version
```
:::
:::{.example #ex-fetchers-fetchurl-nixpkgs-version-postfetch}
# Manipulating the content downloaded by `fetchurl`
It might be useful to manipulate the content downloaded by `fetchurl` directly in its derivation.
In this example, we'll adapt [](#ex-fetchers-fetchurl-nixpkgs-version) to append the result of running the `hello` package to the contents we download, purely to illustrate how to manipulate the content.
```nix
{
fetchurl,
hello,
lib,
}:
fetchurl {
url = "https://raw.githubusercontent.com/NixOS/nixpkgs/23.11/.version";
nativeBuildInputs = [ hello ];
downloadToTemp = true;
postFetch = ''
${lib.getExe hello} >> $downloadedFile
mv $downloadedFile $out
'';
hash = "sha256-ceooQQYmDx5+0nfg40uU3NNI2yKrixP7HZ/xLZUNv+w=";
}
```
After building the package, the resulting file will have "Hello, world!" appended to it:
```shell
$ nix-build
(output removed for clarity)
/nix/store/ifi6pp7q0ag5h7c5v9h1c1c7bhd10c7f-version
$ cat /nix/store/ifi6pp7q0ag5h7c5v9h1c1c7bhd10c7f-version
23.11
Hello, world!
```
Note that the `hash` specified in the package is different than the hash specified in [](#ex-fetchers-fetchurl-nixpkgs-version), because the contents of the output have changed (even though the actual file that was downloaded is the same).
See [](#chap-pkgs-fetchers-caveats) for more details on how to work with the `hash` attribute when the output changes.
:::
## `fetchzip` {#sec-pkgs-fetchers-fetchzip}
Returns a [fixed-output derivation](https://nixos.org/manual/nix/stable/glossary.html#gloss-fixed-output-derivation) which downloads an archive from a given URL and decompresses it.
Despite its name, `fetchzip` is not limited to `.zip` files but can also be used with [various compressed tarball formats](#tar-files) by default.
This can extended by specifying additional attributes, see [](#ex-fetchers-fetchzip-rar-archive) to understand how to do that.
### Inputs {#sec-pkgs-fetchers-fetchzip-inputs}
`fetchzip` requires an attribute set, and most attributes are passed to the underlying call to [`fetchurl`](#sec-pkgs-fetchers-fetchurl).
The attributes below are treated differently by `fetchzip` when compared to what `fetchurl` expects:
`name` (String; _optional_)
: Works as defined in `fetchurl`, but has a different default value than `fetchurl`.
_Default value:_ `"source"`.
`nativeBuildInputs` (List of Attribute Set; _optional_)
: Works as defined in `fetchurl`, but it is also augmented by `fetchzip` to include packages to deal with additional archives (such as `.zip`).
_Default value:_ `[]`.
`postFetch` (String; _optional_)
: Works as defined in `fetchurl`, but it is also augmented with the code needed to make `fetchzip` work.
:::{.caution}
It is only safe to modify files in `$out` in `postFetch`.
Consult the implementation of `fetchzip` for anything more involved.
:::
_Default value:_ `""`.
`stripRoot` (Boolean; _optional_)
: If `true`, the decompressed contents are moved one level up the directory tree.
This is useful for archives that decompress into a single directory which commonly includes some values that change with time, such as version numbers.
When this is the case (and `stripRoot` is `true`), `fetchzip` will remove this directory and make the decompressed contents available in the top-level directory.
[](#ex-fetchers-fetchzip-simple-striproot) shows what this attribute does.
This attribute is **not** passed through to `fetchurl`.
_Default value:_ `true`.
`extension` (String or Null; _optional_)
: If set, the archive downloaded by `fetchzip` will be renamed to a filename with the extension specified in this attribute.
This is useful when making `fetchzip` support additional types of archives, because the implementation may use the extension of an archive to determine whether they can decompress it.
If the URL you're using to download the contents doesn't end with the extension associated with the archive, use this attribute to fix the filename of the archive.
This attribute is **not** passed through to `fetchurl`.
_Default value:_ `null`.
`recursiveHash` (Boolean; _optional_)
: Works [as defined in `fetchurl`](#sec-pkgs-fetchers-fetchurl-inputs-recursiveHash), but its default value is different than for `fetchurl`.
_Default value:_ `true`.
`downloadToTemp` (Boolean; _optional_)
: Works [as defined in `fetchurl`](#sec-pkgs-fetchers-fetchurl-inputs-downloadToTemp), but its default value is different than for `fetchurl`.
_Default value:_ `true`.
`extraPostFetch` **DEPRECATED**
: This attribute is deprecated.
Please use `postFetch` instead.
This attribute is **not** passed through to `fetchurl`.
### Examples {#sec-pkgs-fetchers-fetchzip-examples}
::::{.example #ex-fetchers-fetchzip-simple-striproot}
# Using `fetchzip` to output contents directly
The following recipe shows how to use `fetchzip` to decompress a `.tar.gz` archive:
```nix
{ fetchzip }:
fetchzip {
url = "https://github.com/NixOS/patchelf/releases/download/0.18.0/patchelf-0.18.0.tar.gz";
hash = "sha256-3ABYlME9R8klcpJ7MQpyFEFwHmxDDEzIYBqu/CpDYmg=";
}
```
This archive has all its contents in a directory named `patchelf-0.18.0`.
This means that after decompressing, you'd have to enter this directory to see the contents of the archive.
However, `fetchzip` makes this easier through the attribute `stripRoot` (enabled by default).
After building the recipe, the derivation output will show all the files in the archive at the top level:
```shell
$ nix-build
(output removed for clarity)
/nix/store/1b7h3fvmgrcddvs0m299hnqxlgli1yjw-source
$ ls /nix/store/1b7h3fvmgrcddvs0m299hnqxlgli1yjw-source
aclocal.m4 completions configure.ac m4 Makefile.in patchelf.spec README.md tests
build-aux configure COPYING Makefile.am patchelf.1 patchelf.spec.in src version
```
If `stripRoot` is set to `false`, the derivation output will be the decompressed archive as-is:
```nix
{ fetchzip }:
fetchzip {
url = "https://github.com/NixOS/patchelf/releases/download/0.18.0/patchelf-0.18.0.tar.gz";
hash = "sha256-uv3FuKE4DqpHT3yfE0qcnq0gYjDNQNKZEZt2+PUAneg=";
stripRoot = false;
}
```
:::{.caution}
The hash changed!
Whenever changing attributes of a Nixpkgs fetcher, [remember to invalidate the hash](#chap-pkgs-fetchers-caveats), otherwise you won't get the results you're expecting!
:::
After building the recipe:
```shell
$ nix-build
(output removed for clarity)
/nix/store/2hy5bxw7xgbgxkn0i4x6hjr8w3dbx16c-source
$ ls /nix/store/2hy5bxw7xgbgxkn0i4x6hjr8w3dbx16c-source
patchelf-0.18.0
```
::::
::::{.example #ex-fetchers-fetchzip-rar-archive}
# Using `fetchzip` to decompress a `.rar` file
The `unrar` package provides a [setup hook](#ssec-setup-hooks) to decompress `.rar` archives during the [unpack phase](#ssec-unpack-phase), which can be used with `fetchzip` to decompress those archives:
```nix
{ fetchzip, unrar }:
fetchzip {
url = "https://archive.org/download/SpaceCadet_Plus95/Space_Cadet.rar";
hash = "sha256-fC+zsR8BY6vXpUkVd6i1jF0IZZxVKVvNi6VWCKT+pA4=";
stripRoot = false;
nativeBuildInputs = [ unrar ];
}
```
Since this particular `.rar` file doesn't put its contents in a directory inside the archive, `stripRoot` must be set to `false`.
After building the recipe, the derivation output will show the decompressed files:
```shell
$ nix-build
(output removed for clarity)
/nix/store/zpn7knxfva6rfjja2gbb4p3l9w1f0d36-source

## `fetchpatch` {#fetchpatch}
`fetchpatch` works very similarly to `fetchurl` with the same arguments expected. It expects patch files as a source and performs normalization on them before computing the checksum. For example, it will remove comments or other unstable parts that are sometimes added by version control systems and can change over time.
- `relative`: Similar to using `git-diff`'s `--relative` flag, only keep changes inside the specified directory, making paths relative to it.
- `stripLen`: Remove the first `stripLen` components of pathnames in the patch.
- `decode`: Pipe the downloaded data through this command before processing it as a patch.
- `extraPrefix`: Prefix pathnames by this string.
- `excludes`: Exclude files matching these patterns (applies after the above arguments).
- `includes`: Include only files matching these patterns (applies after the above arguments).
- `revert`: Revert the patch.
Note that because the checksum is computed after applying these effects, using or modifying these arguments will have no effect unless the `hash` argument is changed as well.
Most other fetchers return a directory rather than a single file.
## `fetchDebianPatch` {#fetchdebianpatch}
A wrapper around `fetchpatch`, which takes:
- `patch` and `hash`: the patch's filename,
and its hash after normalization by `fetchpatch` ;
- `pname`: the Debian source package's name ;
- `version`: the upstream version number ;
- `debianRevision`: the [Debian revision number] if applicable ;
- the `area` of the Debian archive: `main` (default), `contrib`, or `non-free`.
Here is an example of `fetchDebianPatch` in action:
```nix
{
lib,
fetchDebianPatch,
buildPythonPackage,
}:
buildPythonPackage rec {
pname = "pysimplesoap";
version = "1.16.2";
src = <...>;
patches = [
(fetchDebianPatch {
inherit pname version;

Patches are fetched from `sources.debian.org`, and so must come from a
package version that was uploaded to the Debian archive. Packages may
be removed from there once that specific version isn't in any suite
anymore (stable, testing, unstable, etc.), so maintainers should use
`copy-tarballs.pl` to archive the patch if it needs to be available
longer-term.
[Debian revision number]: https://www.debian.org/doc/debian-policy/ch-controlfields.html#version
## `fetchsvn` {#fetchsvn}
Used with Subversion. Expects `url` to a Subversion directory, `rev`, and `hash`.
## `fetchgit` {#fetchgit}
Used with Git. Expects `url` to a Git repo, `rev`, and `hash`. `rev` in this case can be full the git commit id (SHA1 hash) or a tag name like `refs/tags/v1.0`.
If you want to fetch a tag you should pass the `tag` parameter instead of `rev` which has the same effect as setting `rev = "refs/tags"/${version}"`.
This is safer than just setting `rev = version` w.r.t. possible branch and tag name conflicts.
Additionally, the following optional arguments can be given:
*`fetchSubmodules`* (Boolean)
: Whether to also fetch the submodules of a repository.
*`fetchLFS`* (Boolean)
: Whether to fetch LFS objects.
*`postFetch`* (String)
: Shell code executed after the file has been fetched successfully.
This can do things like check or transform the file.
*`leaveDotGit`* (Boolean)
: Whether the `.git` directory of the clone should *not* be removed after checkout.
Be warned though that the git repository format is not stable and this flag is therefore not suitable for actual use by itself.
Only use this for testing purposes or in conjunction with removing the `.git` directory in `postFetch`.
*`deepClone`* (Boolean)
: Clone the entire repository as opposing to just creating a shallow clone.
This implies `leaveDotGit`.
*`sparseCheckout`* (List of String)
: Prevent git from fetching unnecessary blobs from server.
This is useful if only parts of the repository are needed.
::: {.example #ex-fetchgit-sparseCheckout}
# Use `sparseCheckout` to only include some directories:
```nix
{ stdenv, fetchgit }:
stdenv.mkDerivation {
name = "hello";
src = fetchgit {
url = "https://...";
sparseCheckout = [
"directory/to/be/included"
"another/directory"
];
hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
};
}
```
:::
See [git sparse-checkout](https://git-scm.com/docs/git-sparse-checkout) for more information.
Some additional parameters for niche use-cases can be found listed in the function parameters in the declaration of `fetchgit`: `pkgs/build-support/fetchgit/default.nix`.
Future parameters additions might also happen without immediately being documented here.
## `fetchfossil` {#fetchfossil}
Used with Fossil. Expects `url` to a Fossil archive, `rev`, and `hash`.
## `fetchcvs` {#fetchcvs}
Used with CVS. Expects `cvsRoot`, `tag`, and `hash`.
## `fetchhg` {#fetchhg}
Used with Mercurial. Expects `url`, `rev`, and `hash`.
A number of fetcher functions wrap part of `fetchurl` and `fetchzip`. They are mainly convenience functions intended for commonly used destinations of source code in Nixpkgs. These wrapper fetchers are listed below.
## `fetchFromGitea` {#fetchfromgitea}
`fetchFromGitea` expects five arguments. `domain` is the gitea server name. `owner` is a string corresponding to the Gitea user or organization that controls this repository. `repo` corresponds to the name of the software repository. These are located at the top of every Gitea HTML page as `owner`/`repo`. `rev` corresponds to the Git commit hash or tag (e.g `v1.0`) that will be downloaded from Git. Finally, `hash` corresponds to the hash of the extracted directory. Again, other hash algorithms are also available but `hash` is currently preferred.
## `fetchFromGitHub` {#fetchfromgithub}
`fetchFromGitHub` expects four arguments. `owner` is a string corresponding to the GitHub user or organization that controls this repository. `repo` corresponds to the name of the software repository. These are located at the top of every GitHub HTML page as `owner`/`repo`. `rev` corresponds to the Git commit hash or tag (e.g `v1.0`) that will be downloaded from Git. If you need to fetch a tag however, you should prefer to use the `tag` parameter which achieves this in a safer way with less boilerplate. Finally, `hash` corresponds to the hash of the extracted directory. Again, other hash algorithms are also available, but `hash` is currently preferred.
To use a different GitHub instance, use `githubBase` (defaults to `"github.com"`).
`fetchFromGitHub` uses `fetchzip` to download the source archive generated by GitHub for the specified revision. If `leaveDotGit`, `deepClone` or `fetchSubmodules` are set to `true`, `fetchFromGitHub` will use `fetchgit` instead. Refer to its section for documentation of these options.
## `fetchFromGitLab` {#fetchfromgitlab}
This is used with GitLab repositories. It behaves similarly to `fetchFromGitHub`, and expects `owner`, `repo`, `rev`, and `hash`.
To use a specific GitLab instance, use `domain` (defaults to `"gitlab.com"`).
## `fetchFromGitiles` {#fetchfromgitiles}
This is used with Gitiles repositories. The arguments expected are similar to `fetchgit`.
## `fetchFromBitbucket` {#fetchfrombitbucket}
This is used with BitBucket repositories. The arguments expected are very similar to `fetchFromGitHub` above.
## `fetchFromSavannah` {#fetchfromsavannah}
This is used with Savannah repositories. The arguments expected are very similar to `fetchFromGitHub` above.
## `fetchFromRepoOrCz` {#fetchfromrepoorcz}
This is used with repo.or.cz repositories. The arguments expected are very similar to `fetchFromGitHub` above.
## `fetchFromSourcehut` {#fetchfromsourcehut}
This is used with sourcehut repositories. Similar to `fetchFromGitHub` above,
it expects `owner`, `repo`, `rev` and `hash`, but don't forget the tilde (~)
in front of the username! Expected arguments also include `vc` ("git" (default)
or "hg"), `domain` and `fetchSubmodules`.
If `fetchSubmodules` is `true`, `fetchFromSourcehut` uses `fetchgit`
or `fetchhg` with `fetchSubmodules` or `fetchSubrepos` set to `true`,
respectively. Otherwise, the fetcher uses `fetchzip`.
## `requireFile` {#requirefile}
`requireFile` allows requesting files that cannot be fetched automatically, but whose content is known.
This is a useful last-resort workaround for license restrictions that prohibit redistribution, or for downloads that are only accessible after authenticating interactively in a browser.
If the requested file is present in the Nix store, the resulting derivation will not be built, because its expected output is already available.
Otherwise, the builder will run, but fail with a message explaining to the user how to provide the file. The following code, for example:
```nix
requireFile {
name = "jdk-${version}_linux-x64_bin.tar.gz";
url = "https://www.oracle.com/java/technologies/javase-jdk11-downloads.html";
hash = "sha256-lL00+F7jjT71nlKJ7HRQuUQ7kkxVYlZh//5msD8sjeI=";
}
```
results in this error message:
```
***
Unfortunately, we cannot download file jdk-11.0.10_linux-x64_bin.tar.gz automatically.
Please go to https://www.oracle.com/java/technologies/javase-jdk11-downloads.html to download it yourself, and add it to the Nix store
using either
nix-store --add-fixed sha256 jdk-11.0.10_linux-x64_bin.tar.gz
or
nix-prefetch-url --type sha256 file:///path/to/jdk-11.0.10_linux-x64_bin.tar.gz
***
```
This function should only be used by non-redistributable software with an unfree license that we need to require the user to download manually.
It produces packages that cannot be built automatically.
## `fetchtorrent` {#fetchtorrent}
`fetchtorrent` expects two arguments. `url` which can either be a Magnet URI (Magnet Link) such as `magnet:?xt=urn:btih:dd8255ecdc7ca55fb0bbf81323d87062db1f6d1c` or an HTTP URL pointing to a `.torrent` file. It can also take a `config` argument which will craft a `settings.json` configuration file and give it to `transmission`, the underlying program that is performing the fetch. The available config options for `transmission` can be found [here](https://github.com/transmission/transmission/blob/main/docs/Editing-Configuration-Files.md#options)
```nix
{ fetchtorrent }:
fetchtorrent {
config = {
peer-limit-global = 100;
};
url = "magnet:?xt=urn:btih:dd8255ecdc7ca55fb0bbf81323d87062db1f6d1c";
hash = "";
}
```
### Parameters {#fetchtorrent-parameters}
- `url`: Magnet URI (Magnet Link) such as `magnet:?xt=urn:btih:dd8255ecdc7ca55fb0bbf81323d87062db1f6d1c` or an HTTP URL pointing to a `.torrent` file.
- `backend`: Which bittorrent program to use. Default: `"transmission"`. Valid values are `"rqbit"` or `"transmission"`. These are the two most suitable torrent clients for fetching in a fixed-output derivation at the time of writing, as they can be easily exited after usage. `rqbit` is written in Rust and has a smaller closure size than `transmission`, and the performance and peer discovery properties differs between these clients, requiring experimentation to decide upon which is the best.
- `config`: When using `transmission` as the `backend`, a json configuration can
be supplied to transmission. Refer to the [upstream documentation](https://github.com/transmission/transmission/blob/main/docs/Editing-Configuration-Files.md) for information on how to configure.

# Fixed-point arguments of build helpers {#chap-build-helpers-finalAttrs}
As mentioned in the beginning of this part, `stdenv.mkDerivation` could alternatively accept a fixed-point function. The input of such function, typically named `finalAttrs`, is expected to be the final state of the attribute set.
A build helper like this is said to accept **fixed-point arguments**.
Build helpers don't always support fixed-point arguments yet, as support in [`stdenv.mkDerivation`](#mkderivation-recursive-attributes) was first included in Nixpkgs 22.05.
## Defining a build helper with `lib.extendMkDerivation` {#sec-build-helper-extendMkDerivation}
Developers can use the Nixpkgs library function [`lib.customisation.extendMkDerivation`](#function-library-lib.customisation.extendMkDerivation) to define a build helper supporting fixed-point arguments from an existing one with such support, with an attribute overlay similar to the one taken by [`<pkg>.overrideAttrs`](#sec-pkg-overrideAttrs).
Beside overriding, `lib.extendMkDerivation` also supports `excludeDrvArgNames` to optionally exclude some arguments in the input fixed-point argumnts from passing down the base build helper (specified as `constructDrv`).
:::{.example #ex-build-helpers-extendMkDerivation}
# Example definition of `mkLocalDerivation` extended from `stdenv.mkDerivation` with `lib.extendMkDerivation`
We want to define a build helper named `mkLocalDerivation` that builds locally without using substitutes by default.
Instead of taking a plain attribute set,
```nix
{
preferLocalBuild ? true,
allowSubstitute ? false,
specialArg ? (_: false),
...
}@args:
stdenv.mkDerivation (
removeAttrs [
# Don't pass specialArg into mkDerivation.
"specialArg"
] args
// {
# Arguments to pass
inherit preferLocalBuild allowSubstitute;
# Some expressions involving specialArg
greeting = if specialArg "hi" then "hi" else "hello";
}
)
```
we could define with `lib.extendMkDerivation` an attribute overlay to make the result build helper also accepts the the attribute set's fixed point passing to the underlying `stdenv.mkDerivation`, named `finalAttrs` here:
```nix
lib.extendMkDerivation {
constructDrv = stdenv.mkDerivation;
excludeDrvArgNames = [
# Don't pass specialArg into mkDerivation.
"specialArg"
];
extendDrvArgs =
finalAttrs:
{
preferLocalBuild ? true,
allowSubstitute ? false,
specialArg ? (_: false),
...
}@args:
{
# Arguments to pass
inherit
preferLocalBuild
allowSubstitute
;
# Some expressions involving specialArg
greeting = if specialArg "hi" then "hi" else "hello";
};
}
```
:::
If one needs to apply extra changes to the result derivation, pass the derivation transformation function to `lib.extendMkDerivation` as `lib.customisation.extendMkDerivation { transformDrv = drv: ...; }`.

# pkgs.appimageTools {#sec-pkgs-appimageTools}
`pkgs.appimageTools` is a set of functions for extracting and wrapping [AppImage](https://appimage.org/) files.
They are meant to be used if traditional packaging from source is infeasible, or if it would take too long.
To quickly run an AppImage file, `pkgs.appimage-run` can be used as well.
::: {.warning}
The `appimageTools` API is unstable and may be subject to backwards-incompatible changes in the future.
:::
## Wrapping {#ssec-pkgs-appimageTools-wrapping}
Use `wrapType2` to wrap any AppImage.
This will create a FHS environment with many packages [expected to exist](https://github.com/AppImage/pkg2appimage/blob/master/excludelist) for the AppImage to work.
`wrapType2` expects an argument with the `src` attribute, and either a `name` attribute or `pname` and `version` attributes.
It will eventually call into [`buildFHSEnv`](#sec-fhs-environments), and any extra attributes in the argument to `wrapType2` will be passed through to it.
This means that you can pass the `extraInstallCommands` attribute, for example, and it will have the same effect as described in [`buildFHSEnv`](#sec-fhs-environments).
::: {.note}
In the past, `appimageTools` provided both `wrapType1` and `wrapType2`, to be used depending on the type of AppImage that was being wrapped.
However, [those were unified early 2020](https://github.com/NixOS/nixpkgs/pull/81833), meaning that both `wrapType1` and `wrapType2` have the same behaviour now.
:::
:::{.example #ex-wrapping-appimage-from-github}
# Wrapping an AppImage from GitHub
```nix
{ appimageTools, fetchurl }:
let
pname = "nuclear";
version = "0.6.30";
src = fetchurl {
url = "https://github.com/nukeop/nuclear/releases/download/v${version}/nuclear-v${version}.AppImage";
hash = "sha256-he1uGC1M/nFcKpMM9JKY4oeexJcnzV0ZRxhTjtJz6xw=";
};
in
appimageTools.wrapType2 {
inherit pname version src;
}
```
:::
The argument passed to `wrapType2` can also contain an `extraPkgs` attribute, which allows you to include additional packages inside the FHS environment your AppImage is going to run in.
`extraPkgs` must be a function that returns a list of packages.
There are a few ways to learn which dependencies an application needs:
- Looking through the extracted AppImage files, reading its scripts and running `patchelf` and `ldd` on its executables.
This can also be done in `appimage-run`, by setting `APPIMAGE_DEBUG_EXEC=bash`.
- Running `strace -vfefile` on the wrapped executable, looking for libraries that can't be found.
:::{.example #ex-wrapping-appimage-with-extrapkgs}
# Wrapping an AppImage with extra packages
```nix
{ appimageTools, fetchurl }:
let
pname = "irccloud";
version = "0.16.0";
src = fetchurl {
url = "https://github.com/irccloud/irccloud-desktop/releases/download/v${version}/IRCCloud-${version}-linux-x86_64.AppImage";
hash = "sha256-/hMPvYdnVB1XjKgU2v47HnVvW4+uC3rhRjbucqin4iI=";
};
in
appimageTools.wrapType2 {
inherit pname version src;
extraPkgs = pkgs: [ pkgs.at-spi2-core ];
}
```
:::
## Extracting {#ssec-pkgs-appimageTools-extracting}
Use `extract` if you need to extract the contents of an AppImage.
This is usually used in Nixpkgs to install extra files in addition to [wrapping](#ssec-pkgs-appimageTools-wrapping) the AppImage.
`extract` expects an argument with the `src` attribute, and either a `name` attribute or `pname` and `version` attributes.
::: {.note}
In the past, `appimageTools` provided both `extractType1` and `extractType2`, to be used depending on the type of AppImage that was being extracted.
However, [those were unified early 2020](https://github.com/NixOS/nixpkgs/pull/81572), meaning that both `extractType1` and `extractType2` have the same behaviour as `extract` now.
:::
:::{.example #ex-extracting-appimage}
# Extracting an AppImage to install extra files
This example was adapted from a real package in Nixpkgs to show how `extract` is usually used in combination with `wrapType2`.
Note how `appimageContents` is used in `extraInstallCommands` to install additional files that were extracted from the AppImage.
```nix
{ appimageTools, fetchurl }:
let
pname = "irccloud";
version = "0.16.0";
src = fetchurl {
url = "https://github.com/irccloud/irccloud-desktop/releases/download/v${version}/IRCCloud-${version}-linux-x86_64.AppImage";
hash = "sha256-/hMPvYdnVB1XjKgU2v47HnVvW4+uC3rhRjbucqin4iI=";
};
appimageContents = appimageTools.extract {
inherit pname version src;
};
in
appimageTools.wrapType2 {
inherit pname version src;
extraPkgs = pkgs: [ pkgs.at-spi2-core ];
extraInstallCommands = ''
mv $out/bin/${pname}-${version} $out/bin/${pname}

substituteInPlace $out/share/applications/irccloud.desktop \
--replace-fail 'Exec=AppRun' 'Exec=${pname}'
'';
}
```
:::
The argument passed to `extract` can also contain a `postExtract` attribute, which allows you to execute additional commands after the files are extracted from the AppImage.
`postExtract` must be a string with commands to run.
:::{.example #ex-extracting-appimage-with-postextract}
# Extracting an AppImage to install extra files, using `postExtract`
This is a rewrite of [](#ex-extracting-appimage) to use `postExtract`.
```nix

let
pname = "irccloud";
version = "0.16.0";
src = fetchurl {

# pkgs.mkBinaryCache {#sec-pkgs-binary-cache}
`pkgs.mkBinaryCache` is a function for creating Nix flat-file binary caches.
Such a cache exists as a directory on disk, and can be used as a Nix substituter by passing `--substituter file:///path/to/cache` to Nix commands.
Nix packages are most commonly shared between machines using [HTTP, SSH, or S3](https://nixos.org/manual/nix/stable/package-management/sharing-packages.html), but a flat-file binary cache can still be useful in some situations.
For example, you can copy it directly to another machine, or make it available on a network file system.
It can also be a convenient way to make some Nix packages available inside a container via bind-mounting.
`mkBinaryCache` expects an argument with the `rootPaths` attribute.
`rootPaths` must be a list of derivations.
The transitive closure of these derivations' outputs will be copied into the cache.
::: {.note}
This function is meant for advanced use cases.
The more idiomatic way to work with flat-file binary caches is via the [nix-copy-closure](https://nixos.org/manual/nix/stable/command-ref/nix-copy-closure.html) command.
You may also want to consider [dockerTools](#sec-pkgs-dockerTools) for your containerization needs.
:::
[]{#sec-pkgs-binary-cache-example}
:::{.example #ex-mkbinarycache-copying-package-closure}
# Copying a package and its closure to another machine with `mkBinaryCache`
The following derivation will construct a flat-file binary cache containing the closure of `hello`.
```nix
{ mkBinaryCache, hello }:
mkBinaryCache {
rootPaths = [ hello ];
}
```
Build the cache on a machine.
Note that the command still builds the exact nix package above, but adds some boilerplate to build it directly from an expression.
```shellSession
$ nix-build -E 'let pkgs = import <nixpkgs> {}; in pkgs.callPackage ({ mkBinaryCache, hello }: mkBinaryCache { rootPaths = [hello]; }) {}'
/nix/store/azf7xay5xxdnia4h9fyjiv59wsjdxl0g-binary-cache
```
Copy the resulting directory to another machine, which we'll call `host2`:
```shellSession
$ scp result host2:/tmp/hello-cache
```
At this point, the cache can be used as a substituter when building derivations on `host2`:
```shellSession
$ nix-build -A hello '<nixpkgs>' \
--option require-sigs false \
--option trusted-substituters file:///tmp/hello-cache \
--option substituters file:///tmp/hello-cache
/nix/store/zhl06z4lrfrkw5rp0hnjjfrgsclzvxpm-hello-2.12.1
```
