Hey, I write here as author of dh_qmldeps a tool to detect QML depdendecies in files. The tool only returns a list of dependencies that are placed into qml6:Depends - as the tool cannot know if the qml file is needed or not. Before wrting this bug report I read the referrenced documation: https://lists.debian.org/debian-devel/2024/03/msg00030.html and https://lists.debian.org/debian-devel/2024/02/msg00230.html. Still I'm not sure how to fix dh_qmldeps or how to do demotion for specific packages. I have several examples where a qml dependecy needs to be demoted in the Qt/KDE maintainer umbrella. (full demotion): kquickimageeditor-dev: only the examples have qml files. That's why recommending all the qml depdendecy seems resonable. The normal usecase of an dev package is to be used to build other packages. Installing the dependencies for examples is too much. (partial demotion): libkf6purpose-bin: A tool to provide functionality allover the plasma desktop to share files and other things. As it support a bunch of different targets. You may want to not install every dependency as you do not want to install kdeconnect so do not depend on qml6-module-org-kde-kdeconnect. And at that time where the recommend was added, qml6-module-org-kde-kdeconnect does not existed yet in unstable. qml6-module-org-kde-purpose is needed to be demoted as otherwise we would face a circular dependency. I know, partion demotion doesn't work within Dh 13 too. So I created a workaround to implement it: After generation the dependency list, go through the Depends/Recommends/... fields in d/control and removes all the explicit mentioned dpendendencies of those fields. https://salsa.debian.org/qt-kde-team/pkg-kde-tools/-/blob/master/pythonlib/qmldeps.py?ref_type=heads#L396 That works and would work in Dh 14 too - but as far as I understand it is against the idea behind the automatic use of the substvars fields, that does not support demotion. At least from the documentation it sounds like the tool (dh_qmldeps) needs to support manipulating the vars. I think it would be great, if there is a way to demote in Dh 14 without the tools to support manipulating. Because if no tool exists than a sed/awk needs to be used and this is error-prune. eg. to demote foo to suggests and "bar" to recommends. # qml6:Depends=foo,bar,zig dh_manipulate --field "qml6" --demote-from Depends --suggests "foo" --recommends "bar" # qml6:Depends=zig # qml6:Suggests=foo # qml6:Recommends=bar The other way would be to specify/recommend the tool API e.g. for dh_qmldeps, dh_python3,...: * support -d parameter for full demotion * support --pre-depends, --recommends, --suggests to promote/demote specific automatic detected depenedencies as pre-depends, recommends, suggests instead of depends Regards, hefee -- System Information: Debian Release: forky/sid APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (500, 'oldstable'), (100, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.19.10+deb14-amd64 (SMP w/8 CPU threads; PREEMPT) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=en_US Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages debhelper depends on: ii autotools-dev 20240727.1 ii dh-autoreconf 22 ii dh-strip-nondeterminism 1.15.0-1 ii dpkg 1.23.7 ii dpkg-dev 1.23.7 ii dwz 0.16-4 ii file 1:5.46-5+b1 ii libdebhelper-perl 13.31 ii libdpkg-perl 1.23.7 ii man-db 2.13.1-1 ii perl 5.40.1-7+b1 ii po-debconf 1.0.22 debhelper recommends no packages.
