pkgtreediff

pkgtreediff compares the NVRs (name-version-release) of RPM packages in OS package trees and/or installations:

• An OS tree can be referenced by an url or directory containing a tree of rpm files.
• A file containing a list(s) of rpm NVRs can also be compared.
• Commands can also be used to get installed RPMs, eg:
  • "rpm -qa"
  • "ssh myhost rpm -qa"
  • "podman run --rm myimage rpm -qa"
• A koji tag: koji://tag@KojiHubUrl (or koji://tag@fedora)

Usage examples

Containers

Compare the content of two rpm based containers versions, filtering for new added packages:

$ pkgtreediff --new "podman run --rm fedora:34 rpm -qa" "podman run --rm fedora:35 rpm -qa"
libfsverity-1.4-4.fc35.x86_64
mpdecimal-2.5.1-2.fc35.x86_64

Package trees

Hosts

Compare the packages on local and another host:

pkgtreediff "rpm -qa" "ssh otherhost rpm -qa"

Any types of sources can be compared, together with the use of flags.

Koji

Compare koji tags using the koji://tag@kojihub syntax:

pkgtreediff koji://dist-c8-updates-build@centos koji://dist-c8_1-updates-build@centos

Please avoid using koji tag to compare full releases as it is more efficient to query URL or CMD trees.

Builds

pkgtreediff is packaged in Fedora.

Older builds are also available in copr for Fedora, EPEL, and OpenSuSE (more details).

RPM version ordering

pkgtreediff use the rpm-nvr library implementation of the rpmvercmp() algorithm, though it has not been verified to behave identically.

RPM version ordering is somewhat involved https://blog.jasonantman.com/2014/07/how-yum-and-rpm-compare-versions/. For example "1.2.1~rc1" < "1.2.1" (greater for ^).
