README: "Not you: team."

Browse source 
Some of the information in the README is outdated, such as the sections
detailing the privileges of known users (everybody is now a known user).
The only distinction made is between that of trusted users and everybody
else. Trusted users gain an additional host to run builds and tests on:
x86_64-darwin. Everybody else is locked to x86_64-linux and
aarch64-linux.

With the removal of all mentions of "known users", the
`config.{extra-,}known-users.json` files have also been removed. This
change will require coordination with the infrastructure repo [1] --
namely, a PR removing references to these files (otherwise, I imagine,
deploys will fail).

Something Graham has mentioned a few times is how he wants to decouple
ofborg from his persona. Thus, `@ofborg` is now used in place of
`@GrahamcOfBorg` everywhere possible (it is still possible to use
`@GrahamcOfBorg`, so it has not been removed from the codebase at this
time).

## Guidelines
1. make sure you've reviewed the code before you trigger it on a PR
that isn't your own
2. be gentle, preferably don't run mass rebuilds / massive builds like
chromium on it
1. Review the code of all PRs before triggering the bot on them.
2. Be gentle; try not to run mass rebuilds or massive builds (like Chromium) on
it.
## Automatic Building
Users who are _trusted_ or _known_ (see: Trusted Users vs Known Users)
will have their PRs automatically trigger builds if their commits
follow the well-defined format of Nixpkgs. Specifically: prefixing the
commit title with the package attribute. This includes package bumps
as well as other changes.
All users will have their PRs automatically trigger builds if their commits
follow the well-defined format of Nixpkgs. Specifically: prefixing the commit
title with the package attribute. This includes package bumps as well as other

If a PR is opened with many commits, it will create a single build job
for all of the detected packages. If a PR is opened and many commits
are pushed one by one to the open PR, many build jobs will be created.
When opening a PR with multiple commits, ofborg creates a single build job for
all detected packages. If multiple commits get pushed to a PR one-by-one, each
detected package will get a separate build job.
To disable automatic building of packages on a PR, add `[WIP]` to the
PR's title, or the `2.status: work-in-progress` label.
If the title of a PR begins with `WIP:`, contains `[WIP]` anywhere, or has the
`2.status: work-in-progress` label, its packages are not built automatically.
**Note**: Marking a PR as a draft does not prevent automatic builds.
## Commands
The comment parser is line-based, so comments can be interleaved with
instructions.
The comment parser is line-based, so commentary can be interwoven with
instructions for ofborg.
1. To trigger the bot, the line _must_ start with a case
insensitive version of `@GrahamcOfBorg`.
2. To use multiple commands, insert a bit of whitespace and then your
new command.
1. To trigger the bot, the line _must_ start with `@ofborg` (case insensitive).
* **Note**: GitHub will not suggest `@ofborg` to you, but it will work all
the same. When in doubt, preview your comment and verify that `@ofborg`
links to https://github.com/ofborg/.
2. To use multiple commands, separate them with whitespace. For examples, see
the "[Multiple Commands](#multiple-commands)" section.
Commands:
### test (added: 2017-11-24)
### test
```
@grahamcofborg test list of tests
@ofborg test list of tests
```
This will run `nix-build ./nixos/release.nix -A tests.list -A tests.of -A tests.tests` in
the nixpkgs checkout. Note: this will only run on x86_64-linux machines.
This will run `nix-build ./nixos/release.nix -A tests.list -A tests.of -A
tests.tests` from the root of the Nixpkgs checkout.
Tests will run on all allowed machines. For more information, see the "[Trusted
Users](#trusted-users)" section.
### eval
```
@grahamcofborg eval
@ofborg eval
```
Note: Every PR automatically evaluates when it is opened and when the
commits change. There is no reason to run eval on a PR unless the
evaluation has failed for weird reasons, or because master was broken
before.
See "[How does ofborg call
`nix-instantiate`?](#how-does-ofborg-call-nix-instantiate)" for what command(s)
this will run.
**Note**: Every PR automatically evaluates both upon creation and when the
commits change. There is no reason to run eval on a PR unless the evaluation
failed for weird reasons or master was previously broken.
### build
```
@grahamcofborg build list of attrs
@ofborg build list of attrs
```
This will run `nix-build ./default.nix -A list -A of -A attrs` in
the nixpkgs checkout.
This will run `nix-build ./default.nix -A list -A of -A attrs` from the root of
the Nixpkgs checkout (see also "[How does ofborg call
`nix-build`?](#how-does-ofborg-call-nix-build)").
---
Builds will run on all allowed machines. For more information, see the "[Trusted
Users](#trusted-users)" section.
## Multiple Commands
Multiple Commands:
You can use multiple commands in a variety ways. Here are some valid
combinations:
*
```
@grahamcofborg build list of attrs
@grahamcofborg eval
@ofborg build list of attrs
@ofborg eval
```
or even:
*
```
@grahamcofborg build list of attrs @grahamcofborg eval
@ofborg build list of attrs @ofborg eval
```
This will also work:
*
```
looks good to me!
@grahamcofborg build list of attrs
@ofborg eval
@ofborg build list of attrs
```
And this is fine:
*
```
@grahamcofborg build list of attrs
@ofborg eval
@ofborg build list of attrs
looks good to me!
```
This is will build `list`, `of`, `attrs`, `looks`, `good`, `to`, `me!`:
*
```
@grahamcofborg build list of attrs looks good to me!
@ofborg build list of attrs
@ofborg test list of attrs
```
## Trusted Users vs Known Users
* This will build `list`, `of`, `attrs`, `looks`, `good`, `to`, and `me!` (which is probably not what you want):
```
@ofborg build list of attrs looks good to me!
```
Known users have their builds executed on platforms with working
sandboxing. At the time of writing, that means:
## Trusted Users
Trusted users have their builds and tests executed on _all_ available platforms,
including those without good sandboxing. Because this exposes the host to a
higher risk of security issues, the trusted users list consists of only
well-known, trusted members of the community.
At the time of writing, trusted users have their builds and tests run on these
platforms:
- `x86_64-linux`
- `aarch64_linux`
Trusted users have their builds executed on _all_ platforms, even if
they don't have good sandboxing. This opens the host up to a higher
risk of security issues, so only well known, trusted member of the
community should be added to the trusted user list.
At the time of writing, trusted users have their builds run on the
following platforms:
- `x86_64-linux`
- `aarch64_linux`
- `aarch64-linux`
- `x86_64-darwin`
See ./config.public.json and ./config.known-users.json for a list of
all the trusted and known users.
See [`config.public.json`](./config.public.json) for a list of all trusted users.
# How does OfBorg call nix-build?
# How does ofborg call `nix-build`?
Builds are run like:

-A hello \
--no-out-link \
--keep-going \
--option restrict-eval true \
--option build-timeout 1800 \
--argstr system thesystem \
--show-trace
```
# How does OfBorg call nix-instantiate?
# How does ofborg call `nix-instantiate`?
NixOS evals are run like:

> HOME=/homeless-shelter NIX_PATH=nixpkgs=$(pwd) nix-instantiate ./nixos/release.nix
> -A manual
> --option restrict-eval true

--argstr system thesystem \
--show-trace
```
Nixpkgs evals are run like:
> HOME=/homeless-shelter NIX_PATH=nixpkgs=$(pwd) nix-instantiate ./pkgs/top-level/release.nix
> -A manual
> --option restrict-eval true
> --option build-timeout 1800
> --argstr system thesystem
> --show-trace
ofborg runs Nixpkgs evals with a command similar to the following:
```shell
$ HOME=/homeless-shelter NIX_PATH=ofborg-nixpkgs-pr=$(pwd) nix-instantiate ./pkgs/top-level/release.nix \
-A manual \
--option restrict-eval true \
--option build-timeout 1800 \
--argstr system thesystem \
--show-trace
```
# Running meta checks locally
```
To run the meta checks, you will need the
[`outpaths.nix`](./ofborg/src/outpaths.nix) file. You can acquire this file and
run the checks themselves like so:
```shell
$ curl -o outpaths.nix https://raw.githubusercontent.com/NixOS/ofborg/released/ofborg/src/outpaths.nix
$ GC_INITIAL_HEAP_SIZE=4g nix-env -f ./outpaths.nix -qaP --no-name --out-path --arg checkMeta true > out-paths
```

# Running a builder
It is recommended to create a special user for the ofBorg operation.
This user should have git configuration for default username/email for
non-interactive merges. For example:
```
git config --global user.email "graham+cofborg@example.com"
git config --global user.name "GrahamCOfBorg"
```
```
nix-shell ./shell.nix
$ cd ofborg
$ cargo build
```
```
cargo build
```
then copy example.config.json to config.json and edit its vars. Set
`nix.remote` to an empty string if you're not using the daemon.
Run
```
./target/debug/builder ./config.json
```
Note the config.public.json for the public pieces of how I run ofborg,
which is merged with config.known-users.json and a third private
config file of credentials. These files contain some special keys like
- known users
- authorized users
- log storage
they are only used in the backend processing tasks, and there is no
need for them on builders. However, to update the list in
config.known-users.json, run `./scripts/update-known-users.sh`.
In case you have a non-trivial setup on Linux, make sure that the ofborg
user has access to `dev/kvm`, as it is needed for running tests.
If you want to run multiple builder instances on the same physical
machine please make sure they use different configs with different
instance identity (same username/password is OK) and different
repository paths. Running two builders with the same config risks data
corruption.

a builder](https://github.com/NixOS/ofborg/wiki/Operating-a-Builder/).
