PacMan Repo Builder

Build a custom pacman repository from a collection of PKGBUILD directories.

Runtime Dependencies

• pacman
• makepkg
• libalpm.so.13
• libgit2.so

Usage

⚠ WARNING: This program is meant to be used within a docker container.

Manifest file

Manifest file is always named build-pacman-repo.yaml. It contains instruction to build a pacman repository.

Example Manifest File:

# build-pacman-repo.yaml
global-settings:
  repository: repo/repo.db.tar.gz
  container: container
  read-build-metadata: either
  record-failed-builds: failed-builds.yaml
  install-missing-dependencies: false
  clean-before-build: false
  clean-after-build: false
  force-rebuild: true
  pacman: pacman
  arch-filter: [x86_64]
  check: inherit
  packager: Bob <[email protected]>
  allow-failure: true
  dereference-database-symlinks: true
members:
  - directory: foo
  - directory: bar
    read-build-metadata: pkgbuild
    clean-before-build: false
    force-rebuild: true
    allow-failure: false
  - directory: bar
    install-missing-dependencies: true
    clean-after-build: false
    check: enabled
    pacman: yay
  - directory: baz
    read-build-metadata: srcinfo
    install-missing-dependencies: false
    clean-before-build: true
    clean-after-build: false
    force-rebuild: true
    check: disabled
    pacman: yay
    allow-failure: false

Field Explanations:

Top-Level:

Field	Type	Description
global-settings	object	Includes global settings from which all members inherit from. Some settings can be overwritten by member customized properties.
member	list	List all members.

global-settings's own fields:

Field	Type	Required/Optional	Description
repository	string	required	Path to repository file (typically ends with .db.tar.gz). It will be passed to repo-add command after each build.
container	string	optional, default = .	Directory that contains all build directories (a.k.a. members).
record-failed-builds	string	optional	If specified, old failed builds shall be skipped, and new failed builds shall be added to the file.
arch-filter	"any" | string[]	optional, default = any	Specify all CPU architectures to build. Either any or an array of strings (e.g. [x86_64, i686]).
packager	string	optional, default = Unknown Packager	Identity of person or entity that produces the packages (i.e. the one who run this program).
dereference-database-symlinks	boolean	optional, default = false	If true, all *.db and *.files symlinks will be converted to real files.

member's own fields:

Field	Type	Required/Optional	Description
directory	string	required	Path to build directory of each member (relative to global-settings.container).

Shared Fields: Fields that exist in both global-settings and member. If global-settings and member both contain a field, member's field will be prioritized.

Field	Type	Default (global-settings)	Description
read-build-metadata	either | srcinfo | pkgbuild	either	Where to read build metadata: srcinfo: From .SRCINFO file. pkgbuild: From output of makepkg --printsrcinfo. either: From .SRCINFO file if it exists, otherwise execute makepkg --printsrcinfo.
install-missing-dependencies	boolean	false	Install packages found in depends and makedepends before each build.
clean-before-build	boolean	false	Clean $srcdir and $pkgdir before each build.
clean-after-build	boolean	false	Clean up after each build.
force-rebuild	boolean	false	Force build even if target package already exists.
check	enabled | disabled | inherit	inherit	Whether to add --check or --nocheck to makepkg command.
pacman	string	pacman	Package manager program to use. The program must recognize pacman's CLI arguments and options.
allow-failure	boolean	false	If false, exits immediately when a build fails. If true, ignore build failure should one occurs.

Generate manifest file

Listing every member in a manifest file can be a chore. So when there are no members with customized properties, you can generate the manifest file to reflect the build directories instead:

build-pacman-repo print-config \
  --repository $repo_dir/$repo_name.db.tar.gz \
  --container build-directories \
  --require-pkgbuild \
  --require-srcinfo \
  --with-install-missing-dependencies true \
  > build-pacman-repo.yaml

Note: Replace $repo_dir with path of your repository directory. This directory will contain all built packages. Note: Replace $repo_name with name of your repository file. This file will be fetched by pacman to check for updates.

Replace /usr/bin/makepkg with one that allows running as root

The normal makepkg script does not allow running as root. While it may make sense in a user's machine, it inconveniences a Docker container.

build-pacman-repo patch-makepkg --replace

Build a pacman repositories

build-pacman-repo build

Note: Make sure that build-pacman-repo.yaml file exists in current working directory.

Frequently Asked Questions

What does this program do?

The main purpose is to build a pacman repository. When the build command is called, it will read all source infos from either .SRCINFO or PKGBUILD, sort them by their dependency relationship, then build them one by one.

Why does this need to be run inside a container?

In order for this program to function properly, it must make several changes to the host system, such as:

• Replace /usr/bin/makepkg with one that allows running as root, so that it may be used in a CI environment.
• Install every built package just in case it may be depended upon by another package.
