Macro %CHANGELOGTEXT - duplicated output

[onosek]

Hi,

rpm -q --qf '%{CHANGELOGTEXT}\n' --specfile <path_to_specfile>

produces duplicated output.

It occurs in Fedora 41 - rpm-4.20.0-1.fc41.x86_64
In older rpm releases in Fedora 40 it is OK rpm-4.19.1.1-1.fc40.x86_64

Tested on specfile like
https://src.fedoraproject.org/rpms/fedpkg/blob/rawhide/f/fedpkg.spec

Originally, this issue was opened for fedpkg:
https://bugzilla.redhat.com/show_bug.cgi?id=2310713 and https://pagure.io/fedpkg/issue/581
but fedpkg clog executes directly rpm and it further processes content which is duplicated or not through rpm versions.

Is it a planned change of behaviour or might it be a bug?

Thanks
ON

That query produces garbage because the query makes no sense. CHANGELOGTEXT tag (not macro) is an array, you need to query appropriately: --qf '[%{CHANGELOGTEXT}\n]'

rpm's own --changelog is literally implemented as:
--qf '[* %{CHANGELOGTIME:day} %{CHANGELOGNAME}\n%{CHANGELOGTEXT}\n\n]'

See https://rpm-software-management.github.io/rpm/manual/queryformat.html for the whole story.

The goal is to get the latest changelog message.
So I would solve my issue by querying:
--qf '[<SEPARATOR>\n%{CHANGELOGTEXT}\n]'
and then splitting the output. This should work even for rpm-4.11
Thanks for the answer.
