# KISS Package Experiment
|
|
|
|
This is an alternative package system I am experimenting with. Instead of the usual `PKGBUILD`, `APKBUILD`, `xbps-template` and `Pkgfile` format, this repository explores a more unixy approach.
|
|
|
|
Each Package is split into multiple files.
|
|
|
|
```sh
|
|
zlib/ # Package name.
|
|
├─ build # Build script.
|
|
├─ depends # Dependencies (one per line).
|
|
├─ sources # Sources (one per line).
|
|
├─ version # Package version.
|
|
┘
|
|
|
|
# Files generated by the package manager.
|
|
├─ manifest # The built package's files and directories.
|
|
├─ checksums # The checksums for the source files.
|
|
┘
|
|
|
|
# Optional files.
|
|
├─ post_install # The script to run after install.
|
|
┘
|
|
```
|
|
|
|
When a built package is installed, this entire directory tree is copied to `/var/db/puke` where it becomes a database entry. Listing the dependencies for a package is a simple as printing the contents of the `depends` file. Searching for which package owns a file is as simple as checking each `manifest` file.
|
|
|
|
This new structure also allows the package manager to be stupid simple. POSIX `sh` has no arrays. However, they are mimicked by looping over each line of each file. No more insecure `depends="pkg pkg pkg"` and `for pkg in $depends`.
|
|
|
|
Instead, the following can be done.
|
|
|
|
```sh
|
|
while read -r depend; do
|
|
# do thing.
|
|
done < depends
|
|
```
|

## `build`
|
|
|
|
The `build` file should contain the necessary steps to patch, configure, build and install the package. When at the install step; the variable `$pkg_dir` is available. This variable points to the directory the package manager uses for built packages. Whatever is in this directory will become part of the package's manifest and will be copied to `/` (or `$PUKE_ROOT`).
|
|
|
|
```sh
|
|
./configure \
|
|
--prefix=/usr \
|
|
--libdir=/lib \
|
|
--shared
|
|
|
|
make
|
|
make DESTDIR="$pkg_dir" install
|
|
```
|
|
|
|
## `manifest`
|
|
|
|
The `manifest` file contains the built package's file and directory list. The full paths to files are listed first and the directories (*in reverse*) follow. This allows the package manager to remove the directories if they're empty without needing checks in-between.
|
|
|
|
```

|
/usr/share/man/man3/zlib.3
|
|
/usr/include/zconf.h
|
|

/lib/pkgconfig
|
|
/lib
|
|
```
|
|
|
|
## `sources`
|
|
|
|
The `sources` file contains the package's sources one per line. Sources can be local or remote.
|
|
|
|
```
|
|
https://www.openssl.org/source/openssl-X.X.X.tar.gz
|
|
patches/fix-musl.patch
|
|
```
|
|
|
|
## `depends`
|
|
|
|
The `depends` file contains the package's dependencies one per line.
|
|
|
|
```
|
|
zlib
|
|
binutils
|
|
openssl
|
|
```
|
|
|
|
## `version`
|
|
|
|
The `version` file contains the package's version as well as its release number. The format of this file is `version release`. The `release` portion allows a package upgrade without the modification of the version number.
|
|
|
|
```
|
|
1.2.11 1
|
|
```
|
|
|
|
## `checksums`
|
|
|
|
The `checksums` file contains the `sha256` sums of each entry in the `sources` file. This is generated and verified automatically.
