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

### 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.
Vieter compiles with the standard Vlang compiler. However, I do maintain a
[mirror](https://git.rustybever.be/vieter-v/v). This is to ensure my CI does
not break without reason, as I control when & how frequently the mirror is
updated to reflect the official repository.
If you encounter issues using the latest V compiler, try using my mirror
instead. `make v` will clone the repository & build the mirror. Afterwards,
prepending any make command with `V_PATH=v/v` tells make to use the locally
compiled mirror instead.

# 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.
