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 (new added packages in fedora:34)

$ pkgtreediff --new "podman run --rm fedora:33 rpm -qa" "podman run --rm fedora:34 rpm -qa"
dejavu-sans-fonts.noarch  2.37-16.fc34
fonts-filesystem.noarch  2.0.5-5.fc34
langpacks-core-en_GB.noarch  3.0-12.fc34
langpacks-core-font-en.noarch  3.0-12.fc34
langpacks-en_GB.noarch  3.0-12.fc34

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

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" (similarly for tilde).

pkgtreediff tries to implement the rpmvercmp() algorithm, but it has not been verified to behave identically.
