depchase
The depchase tool is an simple script to lookup runtime (and/or buildtime) requirements of package(s).
Setup
- python3-solv >= 0.6.30-3.git.2887.97b8c0c (https://copr.fedorainfracloud.org/coprs/ignatenkobrain/libsolv-latest/ as temporary workaround)
- python3-click
- python3-smartcols
Installation
$ python3 setup.py install --user
You need to download files ending in -primary.xml.gz and -filelists.xml.gz and a file repomd.xml for each architecture you want to search through and for the sources. For Fedora rawhide you can download them from here:
- https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/
- https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/source/tree/repodata/
The directory structure should be as follows:
repos
├── sources
│ └── repodata
│ ├── 41989692c9d39640c5e9321b3d3b33ac9677d12cbae4c87a51e2f4f9977dee2e-filelists.xml.gz
│ ├── 85006762236a619d384209fda289d0ff02fc296400bdf48bc1c6a524b499c459-primary.xml.gz
│ └── repomd.xml
└── x86_64
└── repodata
├── 4e9d08a9d6ce135fb28c6a4df1fbabed317e16eba21f7acb814cc6c37ef4cca0-primary.xml.gz
├── 51a55ad79b12153b8c39b9fcceaa88c4f1d208100e9918f5cdf88e89920dedac-filelists.xml.gz
└── repomd.xml
And the repos.cfg file should contain:
[DEFAULT]
basedir = /path/to/the/repos/ # FILL HERE THE CORRECT PATH
[base]
path = ${DEFAULT:basedir}/{arch}
[base-source]
path = ${DEFAULT:basedir}/sources
Usage
$ depchase -a x86_64 -c repos.cfg resolve [--selfhost] foo --hint bar
--selfhost switches to searching of build dependencies
Output
Output is a list of binary and source packages which were required for resolution. You can parse them into multiple files using simple bash script:
#!/bin/bash -eu
PREFIX=$1
> $PREFIX-binary-packages-full.txt
> $PREFIX-binary-packages-short.txt
> $PREFIX-source-packages-full.txt
> $PREFIX-source-packages-short.txt
while read -r nevra; do
[[ "$nevra" == *.src || "$nevra" == *.nosrc ]] && type_="source" || type_="binary"
name=${nevra%-*-*}
echo "$nevra" >> $PREFIX-$type_-packages-full.txt
echo "$name" >> $PREFIX-$type_-packages-short.txt
done
export LC_ALL=C
for f in $PREFIX-{binary,source}-packages-{full,short}.txt; do
sort -u $f -o $f
done
