I chose [V](https://vlang.io/) as I've been very intrigued by this language for
a while now. I wanted a fast language that I could code while relaxing, without
having to exert too much mental effort & V seemed like the right choice for
that. Sadly, this didn't quite turn out the way I expected, but I'm sticking
with it anyways ;p
that.
## Features
@ -48,9 +47,9 @@ update`.
### Compiler
V is developed using a specific compiler commit that is usually updated
whenever a new version is released. Information on this can be found in the
[tools](https://git.rustybever.be/vieter-v/tools) repository.
I used to maintain a mirror that tracked the latest master, but nowadays, I
maintain a Docker image containing the specific compiler version that Vieter
builds with. Currently, this is V 0.3.

* Packages with architecture `any` are always added to this architecture.
This prevents the server from being confused when an `any` package is
published as the very first package for a repository.
* Targets added without an `arch` value use this value instead.
* `global_schedule`: build schedule for any target that does not have a
schedule defined. For information about this syntax, see
[here](/usage/builds/schedule).
* Default: `0 3` (3AM every night)
* `base_image`: Docker image to use when building a package. Any Pacman-based
distro image should work, as long as `/etc/pacman.conf` is used &
`base-devel` exists in the repositories. Make sure that the image supports
the architecture of your cron daemon.
* Default: `archlinux:base-devel` (only works on `x86_64`). If you require
`aarch64` support, consider using
[`menci/archlinuxarm:base-devel`](https://hub.docker.com/r/menci/archlinuxarm)
([GitHub](https://github.com/Menci/docker-archlinuxarm)). This is the
image used for the Vieter CI builds.
* `max_log_age`: maximum age of logs (in days). Logs older than this will get
cleaned by the log removal daemon. If set to zero, no logs are ever removed.
The age of logs is determined by the time the build was started.

* `api_key`: API key of the above server.
* `data_dir`: directory to store log file in.
* `max_concurrent_builds`: how many builds to run at the same time.
* Default: `1`
* `polling_frequency`: how often (in seconds) to poll the server for new
builds. Note that the agent might poll more frequently when it's actively
processing builds.
* `image_rebuild_frequency`: Vieter periodically builds images that are then
used as a basis for running build containers. This is to prevent each build
from downloading an entire repository worth of dependencies. This setting
defines how frequently (in minutes) to rebuild these images.
* Default: `1440` (every 24 hours)
* `arch`: architecture for which this agent should pull down builds (e.g.
`x86_64`)

Builds are executed on the agent's system using the host's Docker daemon. An
agent for a specific `arch` will only build packages for that specific
architecture. Therefore, if you wish to build packages for both `x86_64` &
`aarch64`, you'll have to deploy two agents, one on each architecture.
Afterwards, any Git repositories enabled for those two architectures will build

# Builds In-depth
For those interested, this page describes how the build system works
internally.
## Builder image
Every cron daemon perodically creates a builder image that is then used as a
base for all builds. This is done to prevent build containers having to pull
down a bunch of updates when they update their system.
The build container is created by running the following commands inside a
container started from the image defined in `base_image`:
```sh
# Update repos & install required packages
pacman -Syu --needed --noconfirm base-devel git
# Add a non-root user to run makepkg
groupadd -g 1000 builder
useradd -mg builder builder
# Make sure they can use sudo without a password
echo 'builder ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers
# Create the directory for the builds & make it writeable for the
# build user
mkdir /build
chown -R builder:builder /build
```
This script updates the packages to their latest versions & creates a non-root
user to use when running `makepkg`.
This script is base64-encoded & passed to the container as an environment
variable. The container's entrypoint is set to `/bin/sh -c` & its command
argument to `echo $BUILD_SCRIPT | base64 -d | /bin/sh -e`, with the
`BUILD_SCRIPT` environment variable containing the base64-encoded script.
Once the container exits, a new Docker image is created from it. This image is
then used as the base for any builds.
## Running builds
Each build has its own Docker container, using the builder image as its base.
The same base64-based technique as above is used, just with a different script.
To make the build logs more clear, each command is appended by an echo command
printing the next command to stdout.
Given the Git repository URL is `https://examplerepo.com` with branch `main`,
the URL of the Vieter server is `https://example.com` and `vieter` is the
repository we wish to publish to, we get the following script:
```sh
echo -e '+ echo -e '\''[vieter]\\nServer = https://example.com/$repo/$arch\\nSigLevel = Optional'\'' >> /etc/pacman.conf'
echo -e '[vieter]\nServer = https://example.com/$repo/$arch\nSigLevel = Optional' >> /etc/pacman.conf
echo -e '+ pacman -Syu --needed --noconfirm'
pacman -Syu --needed --noconfirm
echo -e '+ su builder'
su builder
echo -e '+ git clone --single-branch --depth 1 --branch main https://examplerepo.com repo'
git clone --single-branch --depth 1 --branch main https://examplerepo.com repo
echo -e '+ cd repo'
cd repo
echo -e '+ makepkg --nobuild --syncdeps --needed --noconfirm'
makepkg --nobuild --syncdeps --needed --noconfirm
echo -e '+ source PKGBUILD'
source PKGBUILD
echo -e '+ curl -s --head --fail https://example.com/vieter/x86_64/$pkgname-$pkgver-$pkgrel && exit 0'
curl -s --head --fail https://example.com/vieter/x86_64/$pkgname-$pkgver-$pkgrel && exit 0
echo -e '+ [ "$(id -u)" == 0 ] && exit 0'
[ "$(id -u)" == 0 ] && exit 0
echo -e '+ MAKEFLAGS="-j$(nproc)" makepkg -s --noconfirm --needed && for pkg in $(ls -1 *.pkg*); do curl -XPOST -T "$pkg" -H "X-API-KEY: $API_KEY" https://example.com/vieter/publish; done'
MAKEFLAGS="-j$(nproc)" makepkg -s --noconfirm --needed && for pkg in $(ls -1 *.pkg*); do curl -XPOST -T "$pkg" -H "X-API-KEY: $API_KEY" https://example.com/vieter/publish; done
```
This script:
1. Adds the target repository as a repository in the build container
2. Updates mirrors & packages
3. Clones the Git repository
4. Runs `makepkg` without building to calculate `pkgver`
5. Checks whether the package version is already present on the server
6. If not, run `makepkg` & publish any generated package archives to the server

# Cleanup
Vieter stores the logs of every single package build. While this is great for
debugging why builds fail, it also causes an active or long-running Vieter
instance to accumulate thousands of logs.
To combat this, a log removal daemon can be enabled that periodically removes
old build logs. By starting your server with the `max_log_age` variable (see
[Configuration](/configuration#vieter-server)), a daemon will get enabled that
periodically removes logs older than this setting. By default, this will happen
every day at midnight, but this behavior can be changed using the
`log_removal_schedule` variable.
{{< hint info >}}
**Note**
The daemon will always run a removal of logs on startup. Therefore, it's
possible the daemon will be *very* active when first enabling this setting.
After the initial surge of logs to remove, it'll calm down again.

# repo
This module manages the contents of the various repositories stored within a
Vieter instance.
## Terminology
* Arch-repository (arch-repo): specific architecture of a given repository. This is what
Pacman actually uses as a repository, and contains its own `.db` & `.files`
files.
* Repository (repo): a collection of arch-repositories. A single repository can
contain packages of different architectures, with each package being stored
in that specific architecture' arch-repository.
* Repository group (repo-group): a collection of repositories. Each Vieter
instance consists of a single repository group, which manages all underlying
repositories & arch-repositories.
## Arch-repository layout
An arch-repository (aka a regular Pacman repository) consists of a directory
with the following files (`{repo}` should be replaced with the name of the
repository):
* One or more package directories. These directories follow the naming scheme
`${pkgname}-${pkgver}-${pkgrel}`. Each of these directories contains two
files, `desc` & `files`. The `desc` file is a list of the package's metadata,
while `files` contains a list of all files that the package contains. The
latter is used when using `pacman -F`.
* `{repo}.db` & `{repo}.db.tar.gz`: the database file of the repository. This
is just a compressed tarball of all package directories, but only their
`desc` files. Both these files should have the same content (`repo-add`
creates a symlink, but Vieter just serves the same file for both routes)
* `{repo}.files` & `{repo}.files.tar.gz`: the same as the `.db` file, but this
also contains the `files` files, instead of just the `desc` files.
## Filesystem layout
The repository part of Vieter consists of two directories. One is the `repos`
directory inside the configured `data_dir`, while the other is the configured
`pkg_dir`. `repos` contains only the repository group, while `pkg_dir` contains
the actual package archives. `pkg_dir` is the directory that can take up a
significant amount of memory, while `repos` solely consists of small text
files.
