Goal

Generate a graph of all packages that require any of the provides of a package for SUSE and openSUSE). This use zypper with --requires-pkg option on current system, so its using the actual Repositories set on the system. If you are using some extra repository this can report false result compare to an '''official''' installation. To avoid any false result it is recommended to use the container way.

SUSE SLES case

To be able to access all repositories you need an SCC credentials, and the container requires a writable file, and as use there is some limitation, so you need as root to change the ACL on the file:

setfacl -m u:aginies:r /etc/zypp/credentials.d/SCCcredentials

About SCC and credentials, look at the online documentation at https://scc.suse.com/docs/userguide

Usage

First clone this repo:

git clone https://github.com/aginies/graph_requires.git

Switch the script to executable and use it on your system:

cd graph_requires
chmod 755 graph_requires.py
./graph_requires.py PACKAGE_NAME,PKG2,PKG3 [OPTIONNAL_DIRECTORY]

Example

./graph_requires.py qemu

Generate a graph of packages which requires another one.
This use zypper on current system, so using the actual Repositories set on this system.

Working with package qemu

Container

This provide you a clean environement to check requires.

Build the container:

./graph-container-manage.sh build
1. openSUSE Leap 15.5
2. openSUSE Leap 15.6
3. openSUSE Tumbleweed
4. SUSE SLES 15SP5
5. SUSE SLES 15SP6

Enter your OS choice [1-5]: 2
STEP 1/23: FROM opensuse/leap:15.6
STEP 2/23: LABEL Description="Graph requires Container"
..............

Use it:

./graph-container-manage.sh run
./graph-container-manage.sh run
localhost/graph-sles15-sp6      latest      7f7bfcf697fc  3 seconds ago  223 MB
Enter the container ID: 7f7bfcf697fc
Enter the package name (separated by comma): qemu,libvirt

Generate a graph of all packages that require any of the provides of a package.
This use zypper on current system, so using the actual Repositories set on the system.

Limit

If you try to graph what requires glibc... don't expect any result soon, this can be very slow to render...

TODO

• fix limit filename size
• avoid redundant loop in graph
