PACKAGE SYSTEM
=================================================================================
This document talks about the packaging system works with the kiss package
manager in detail. For information regarding the usage of the package manager
itself, see the kiss(1) manual page.
A package is formed of 4 MANDATORY files. These are,
- BUILD
- SOURCES
- CHECKSUMS
- VERSION
The package manager also reacts to the existence of these files,
- DEPENDS
- POST-INSTALL
- MESSAGE
Any other file can be added to the package directory at the discretion of the
package maintainer. Everything in the package directory will also be added to the
package database that is located on '/var/db/kiss/installed'. These can be
patches, configuration files, etc.
BUILD
---------------------------------------------------------------------------------
Typically build files are shell scripts that run commands to prepare the source
code to be installed on the target system. Even though we will be assuming that
the build file is a POSIX shell script (for portability's sake), build files can
be any executable program from binary programs to Perl scripts.
The contents of a build script do not need to follow a certain rule for the
package manager, except for the fact that the user needs the permission to
execute the file.
An important advice is to append an '-e' to the shebang (#!/bin/sh -e) so that
the build script exits on compilation error.
Build is run with three arguments
$1: Location of the package directory (DESTDIR)
$2: Package version
$3: System Architecture
SOURCES
---------------------------------------------------------------------------------
sources file is a list of files and sources that will be put to the build
directory during the build process. Those can be remote sources (such as
tarballs), git repositories, and files that reside on the package directory.
The SYNTAX is pretty simple for the sources file. Here are some example 'sources'
files taken from the packages in the repository.
BUSYBOX
https://busybox.net/downloads/busybox-1.31.1.tar.bz2
files/.config
files/.config-suid
files/acpid.run
files/crond.run
files/inittab
files/ntpd.run
files/syslogd.run
files/ntp.conf
patches/fsck-resolve-uuid.patch
patches/modprobe-kernel-version.patch
patches/adduser-no-setgid.patch
patches/install-fix-chown.patch
patches/print-unicode.patch
patches/1-date-64-prefix.patch
patches/2-time-64-prefix.patch
patches/3-syscall-gettime.patch
SINIT
git+git://git.suckless.org/sinit#v1.1
files/config.h
files/reboot
files/poweroff
GST-PLUGINS
https://gstreamer.freedesktop.org/src/gst-plugins-good/gst-plugins-good-1.16.2.tar.xz good
https://gstreamer.freedesktop.org/src/gst-plugins-bad/gst-plugins-bad-1.16.2.tar.xz bad
https://gstreamer.freedesktop.org/src/gst-plugins-ugly/gst-plugins-ugly-1.16.2.tar.xz ugly
https://gstreamer.freedesktop.org/src/gst-libav/gst-libav-1.16.2.tar.xz libav
This file is read from the package manager as space seperated. Files that begin
with a '#' comment are ignored. The first value points to the location of the
source.
If it starts with a protcol url, (such as ftp:// http:// https://) it will be
downloaded with curl(1).
If the source is GIT repository, it shall be prefixed with a 'git+'. git(1) will
be used to do a shallow clone of the repository. If the commit is suffixed by a
history pointer, git will checkout the relevant revision. So,
- git+git://example.com/pub/repo#v1.2.3 will checkout the tag named 'v1.2.3'
- git+git://example.com/pub/repo#development will checkout the branch named 'development'
- git+git://example.com/pub/repo#1a314s87 will checkout the commit named '1a314s87'
Other files are assumed to be residing in the package directory. They should be
added with their paths relative to the package directory.
The optional second value marks the DESTINATION of the source. If the value is
'example', the source will be extracted to a directory named 'example'. This is
useful on cases where there are multiple sources, or where a software requires
a source to be on a specific directory, you can see the gcc package for that.
CHECKSUMS
---------------------------------------------------------------------------------
checksums file is generated by the `kiss c pkg` command. It is generated
according to the order of the sources file. That's why you shouldn't be editing
it manually. The checksums file is created with the digests of the files using
the sha256 algorithm.
VERSION
---------------------------------------------------------------------------------
The version file includes the version of the software and the release number of
of the package on a space seperated format. The contents of the file should look
like below.
1.3.2 1
The version should always match to the number of the upstream release. For
drastic changes that require a rebuild Those can be,
- update of libraries that forces the package to be relinked
- change in the build scripts that affect the output of the package
When a version bump occurs, the release should be reset to 1.
DEPENDS
---------------------------------------------------------------------------------
This is a list of dependencies that must be installed before a package build. You
can append 'make' after a dependency to mark a package is only required during
the build process of a package. Packages marked as a make dependency can be
removed after the build.
POST-INSTALL
---------------------------------------------------------------------------------
post-installs have the same requirements as the build script. They will be run
after the package is installed as root (or as the user if the user has write
permissions on KISS_ROOT).
MESSAGE
---------------------------------------------------------------------------------
This plaintext file will be outputted with 'cat(1)' after every package is
installed.
