Garuda Linux PKGBUILDs

This repository contains PKGBUILDs for all packages that currently reside in its garuda repository. It is operated on GitLab due to making extensive use of its CI and has a read-only GitHub mirror.

Scope of this repo

All of our own PKGBUILDs are contained here. Historically, these were split into their own repositories. To make finding the correct PKGBUILD easier, as well as to allow faster contributing, we recently consolidated them into this new repository. Included are all packages' PKGBUILDs including their configuration files (this applies to smaller files like the garuda-fish-config). For some of them, like the garuda-*-settings packages, the content may still be found in their respective repositories.

If any packaging issues or similar things occur, don't hesitate to report them via our issues section. You can click here to create a new one.

How to contribute?

We highly appreciate contributions of any sort! ? To do so, please follow these steps:

• Create a fork of this repository.
• Clone your fork locally (short git tutorial).
• Add the desired changes to PKGBUILDs or source code.
• Ensure shellcheck and shfmt report no issues with the changed files
  • The needed dependencies need to be installed before, eg. via sudo pacman -S shfmt shellcheck
  • Run the lint.sh script via bash ./.ci/lint.sh check the code
  • Automatically apply certain suggestions via bash ./ci/lint.sh apply
• Commit using a conventional commit message and push any changes back to your fork.
  • The commitizen application helps with creating a fitting commit message. You can install it via pip as there is currently no package in Arch repos: pip install --user -U Commitizen. Then proceed by running cz commit in the cloned folder.
• Create a new merge request at our main repository.
• Check if any of the pipeline runs fail and apply eventual suggestions.

We will then review the changes and eventually merge them.

Handling certain packaging issues

Deprecated and broken packages

There are cases of deprecated packages, which serve no purpose anymore and also cause systems to not be able to update. These can be handled by adding the package to conflicts() of garuda-common-settings and auto-pacman of garuda-update. The result is that the offending package gets removed automatically due to the conflict.

CI / build tools

The following is partially taken from the build tools documentation, omitting information not relevant to this repo. In case you are looking for setup instructions, please it's full README instead.

General

Deployments may automatically be triggered by either changing content inside a PKGBUILD directory or appending [deploy *] to the commit message. Unlike the PKGBUILD checks, these are only available for commits on the main branch. Supported are:

• [deploy all]: Deploys a full garuda routine, meaning all PKGBUILDs in this repository.
• [deploy $pkgname]: Deploys the package pkgname, which means that by replacing this with garuda-bash-settings, one would deploy garuda-bash-settings.

Once any of those combinations gets detected, the deployment starts after a few checks are completed successfully. Logs of past deployments may be inspected via the Pipelines section.

Automated bumps

This repository provides a half-hourly pipeline that updates all PKGBUILDs to their latest versions if their source resides in another repository, based on the latest available tag. It then proceeds to update the checksums and pushes the changes back to the main branch. A new deployment is automatically triggered by appending [deploy *] to the commit message. That means it is sufficient to push a new tag in order to trigger the deployment of a new package version for these packages. Important notice:

• This does not apply to packages which have all their files in this repository
• Tags must not be prefixed with a v
• Needed information about a package's source are provided via the SOURCES file. Each line follows the scheme $url $pkgname $project_id. The latter is used to retrieve the latest tag via GitLab API and can be found at the general settings page of the repository.

The latest runs of this job may be inspected by browsing the pipelines section, every pipeline with the scheduled badge was executed by the timer. Additionally, the pipeline can be triggered manually by browsing the pipeline schedules section and hitting run pipeline schedule.

Manually updating versions

For some PKGBUILDs, like garuda-fish-config, all files reside in this repository. When updating PKGBUILDs, please ensure to also update the corresponding .SRCINFO file as this one is used to parse all package related information!

Adding packages

Adding packages is as easy as creating a new folder named after the $pkgbase of the package. Put the PKGBUILD and all other required files in here. Adding AUR packages is therefore as simple as cloning its repo and removing the .git folder. CI relies on .SRCINFO files to parse most information, therefore, it is important to have them in place and up-to-date in case of self-managed packages. Finally, add a .CI folder containing the basic config (CI_PKGBUILD_SOURCE is required in case its external package, self-managed PKBUILDs don't need it), commit any changes, and push the changes back to the main branch. Please follow the conventional commit convention while doing so (cz-cli can help with that!). This means commits like:

• feat($pkgname): init
• fix($pkgname): fix xyz
• chore($pkgname): update PKGBUILD
• ci(config): update

This not only helps with having a uniform commit history, it also allows automatic changelog generation.

Removing packages

This can be done by removing the folder containing a package's PKGBUILD. A cleanup job will then automatically remove any obsolete package via the on-commit pipeline run. This will also consider any split packages that a package might produce. Renaming folders does also count as removing packages.

On-commit pipeline

Whenever pushing a new commit, the CI pipeline will carry out the following actions:

• Checking when the last scheduled tag was created. This is used to determine which packages need to be scheduled.
• It parses each commit for a [deploy $foldername] string, only accepting valid values derived from the existing PKGBUILD folders. [deploy all] is a valid parameter as well. Misspelling $pkgname is a fatal error here. Any issues must be fixed and force-pushed.
• Then, the changed files are parsed. This also includes removed packages. Any changed relevant folder content will cause a package deployment of the corresponding package.
• The final action is to build the schedule parameters (handing it over to the scheduled job via artifacts) and remove all obsolete packages in case an earlier step is detected.
• In case all of these actions succeed, the scheduled tag gets updated, so we can refer to it on a later pipeline run.

On-schedule pipeline

Half-hourly

Every half an hour, the on-schedule pipeline will carry out a few tasks:

• Updating the CI template from the template repository (in case this is enabled via .ci/config)
• Check if the scheduled tag does not exist or scheduled does not point to HEAD (in this case abort mission!)
• Check whether the .state worktree containing the state of the packages exists, if it does, it sets it up. Otherwise, it re-creates it from scratch (e.g., on force push)
• Check whether the last commit is automated (containing "chore(packages): update packages [skip ci]"), if yes, the commit resulting from the schedule will overwrite it to keep the commit history clean.
• Collect AUR timestamps of packages to determine whether a PKGBUILD changed
• Loop through each valid package and carry out the following actions:
  • Read the .CI/config file to gain information about the package configuration (e.g., whether to manage the AUR repository, the source of the PKGBUILD, etc.)
  • Update PKGBUILD in the following cases:
    • CI_PKGBUILD_SOURCE is set to gitlab: Updates the PKGBUILD from the GitLab repository tags
    • CI_PKGBUILD_SOURCE is set to aur: Updates the PKGBUILD from the AUR repository, pulling in the git repo and replacing the existing files with the new ones. If the AUR timestamp could not be collected earlier, the package update gets skipped.
    • CI_PKGBUILD_SOURCE is not set to gitlab or aur: tries to update the PKGBUILD by pulling the repository specified in CI_PKGBUILD_SOURCE. In case cloning was not successful after 2 tries, the update process gets skipped.
  • In case CI_GIT_COMMIT is set in the packages configuration variables, the latest commit of the git URL set in the source section of the PKGBUILD is updated. If it differs, schedule a build.
  • In case a custom hook exists (.CI/update.sh inside the package directory), it gets executed - this can be used for updating PKGBUILDs with a custom script.
  • Writing needed variables back to .CI/config (eg. Git hash)
• Either update the PKGBUILD silently in case of minor changes, create a PR for review in case of major updates (and only if CI_HUMAN_REVIEW is true)
  • Updates are only considered if diff actually reports changes between current PKGBUILD folder and AUR PKGBUILD repo
  • Any change made to the source files is detected, this however does not detect malicious changes in the upstream project source that the package builds
• The state worktree gets updated with new information
• Schedule parameters are getting built and handed over to the scheduled job via artifact
• Obsolete branches (eg. merged review PRs) are getting pruned
• The scheduled tag gets updated again

Daily

A daily pipeline schedule has been added for specific packages which generate their pkgver dynamically. To make use of it, set CI_ON_TRIGGER=daily inside the .CI/config file of the package.

Manual scheduling

Scheduling packages without git commits

Packages can be added to the schedule manually by going to the pipeline runs page, selecting "Run pipeline" and adding PACKAGES as a variable with the package names as its value. The pipeline will then pick up the packages and schedule them. PACKAGES can also be set to all to schedule all packages. In case one or many packages are getting scheduled, it needs to follow the format pkgname1:pkgname2:pkgname3.

Running scheduled pipelines on-demand

This can be done by going to the pipeline runs page, selecting "Run pipeline" (the play symbol). A link to the pipeline page will be provided, where the pipeline logs can be obtained.

Adding interfere

Put the required interfere file in the .CI folder of a PKGBUILD folder:

• prepare: A script that is being executed after the building chroot has been set up. It can be used to source environment variables or modify other things before compilation starts.
  • If something needs to be set up before the actual compilation process, commands can be pushed by inserting eg. $CAUR_PUSH 'source /etc/profile'. Likewise, package conflicts can be solved, eg. as follows: $CAUR_PUSH 'yes | pacman -S nftables' (single quotes are important because we want the variables/pipes to evaluate in the guest's runtime and not while interfering)
• interfere.patch: a patch file that can be used to fix either multiple files or PKGBUILD if a lot of changes are required. All changes need to be added to this file.
• PKGBUILD.prepend: contents of this file are added to the beginning of PKGBUILD.
• PKGBUILD.append: contents of this file are added to the end of PKGBUILD. Fixing build() as is easy as adding the fixed build() into this file. This can be used for all kinds of fixes. If something needs to be added to an array, this is as easy as makedepend+=(somepackage).
• on-failure.sh: A script that is being executed if the build fails.
• on-success.sh: A script that is being executed if the build succeeds.

Bumping pkgrel

This is now carried out by adding the required variable CI_PACKAGE_BUMP to .CI/config. See below for more information.

Dependency trees

The CI builds dependency trees automatically. They are passed to the Chaotic manager as a CI artifact and read whenever a schedule command is being executed. No manual intervention is needed.

.CI/config

The .CI/config file inside each package directory contains additional flags to control the pipelines and build processes with.

• CI_MANAGE_AUR: By setting this variable to true, the CI will update the corresponding AUR repository at the end of a pipeline run if changes occur (omitting CI-related files)
• CI_PACKAGE_BUMP: Controls package bumps for all packages which don't have CI_MANAGE_AUR set to true. It increases pkgrel by 0.1 for every +1 increase of this variable.
• CI_PKGBUILD_SOURCE: Sets the source for all PKGBUILD-related files, used for pulling updated files from remote repositories. Valid values as of now are:
  • gitlab: Pulls the PKGBUILD from the GitLab repository tags. It needs to follow the format gitlab:$PROJECT_ID. The ID can be obtained by browsing the repository settings general section.
  • aur: Pulls the PKGBUILD from the AUR repository, pulling in the git repo and replacing the existing files with the new ones.
• CI_ON_TRIGGER: Can be provided in case a special schedule trigger should schedule the corresponding package. This can be used to schedule packages daily, by setting the value to daily. Since this checks whether "$TRIGGER == $CI_ON_TRIGGER", any custom schedule can be created using pipeline schedules and setting TRIGGER to midnight, adding a fitting schedule and setting CI_ON_TRIGGER for any affected package to midnight.
• CI_REBUILD_TRIGGERS: Add packages known to be causing rebuilds to this variable. A list of repositories to track package versions for is provided via the repositories' CI_LIB_DB parameter. Each package version is hashed and dumped to .ci/lib.state. Each scheduled pipeline run compares versions by checking hash mismatches and will bump each each affected package via CI_PACKAGE_BUMP.
• BUILDER_CACHE_SOURCES: Can be set to true in case the sources should be cached between builds. This can be useful in case of slow sources or sources that are not available all the time. Sources will be cleared automatically after 1 month, which is important in case packages are getting removed or the source changes.

Managing AUR packages

AUR packages can also be managed via this repository in an automated way using .CI_CONFIG. This means that after each scheduled and on-commit pipeline, the AUR repository will be updated to reflect the changes done to the PKGBUILD folder's files. Files not relevant to AUR maintenance (e.g. .CI folders) will be omitted. The commit message reflects the fact that the commit was created by a CI pipeline and contains the link to the source repository's commit history and the pipeline run which triggered the update commit.

Updating the CI's scripts

This is done automatically via the CI pipeline. Once changes have been detected on the template repository, all files will be updated to the current version.

Issues and pipeline failures

Last on-commit pipeline failed

This can happen in case of a few reasons, for example having provided an invalid package name. This causes the scheduled tag to not be updated. In this case, the on-schedule pipeline will not be able to run. The last on-commit pipeline needs to be fixed before the on-schedule pipeline can run again. Build failures however are not accounted as the scheduled tag would be updated already as soon as the scheduling parameters were generated. Force pushing a fixed up commit is actively encouraged in such a case, as pushing another commit will cause the CI to evaluate the previous commits it missed, leading to noticing the same issue again and bailing out instead of silently continuing. This has been a design decision to prevent failures from being overlooked.

Resetting the build queue

There might be rare cases in which a reset of the build queue is needed. This can be done by shutting down the central Redis instance, removing its dump, and restarting its service.

Chaotic Manager

This tool is distributed as Docker containers and consists of a pair of manager and builder instances.

• Manager: registry.gitlab.com/garuda-linux/tools/chaotic-manager/manager
• Builder: registry.gitlab.com/garuda-linux/tools/chaotic-manager/builder
  • This one contains the actual logic behind package builds (seen here) known from infra 3.0 like interfere.sh, database.sh etc.
  • Picks packages to build from the Redis instance managed by the manager instance

The manager is used by GitLab CI in the schedule-package job, scheduling packages by adding it to the build queue. The builder can be used by any machine capable of running the container. It will pick available jobs from our central Redis instance.

Development setup

This repository features a NixOS flake, which may be used to set up the needed things like pre-commit hooks and checks, as well as needed utilities, automatically via direnv. This includes checking PKGBUILDs via shellcheck and shfmt. Needed are nix (the package manager) and direnv, after that, the environment may be entered by running direnv allow.
