Fedora 43 KDE Copr x86_64-v3 Builder

This repository now targets Copr rather than doing local rpmbuild -ba work inside CI. It uses Copr's SCM make_srpm flow to generate SRPMs from repo-local Fedora packaging snapshots stored under SPECS/<package>/, and installs a dedicated buildroot macro package so Copr's Fedora 43 x86_64 builders compile with an x86-64-v3 ISA baseline.

What changed

• .copr/Makefile is the Copr entrypoint used by the SCM make_srpm method.
• SPECS/<package>/ stores the pre-fetched Fedora dist-git snapshot for each package.
• ci/prefetch-fedora-specs.py refreshes those snapshots from Fedora dist-git.
• ci/copr-distgit-make-srpm.py builds SRPMs from the local SPECS/ snapshots and downloads lookaside sources.
• packaging/copr-rpm-macros-x86-64-v3.spec produces the buildroot macro package that changes Fedora's %__cflags_arch_x86_64_level to -v3 while keeping the rest of redhat-rpm-config intact.
• ci/sync-copr-packages.py registers or updates Copr SCM package definitions and can queue builds.

Why the macro package exists

Copr does not expose a generic rpmbuild --define interface for package builds. The supported way to change buildroot macros is to build a small RPM that drops a file into %{rpmmacrodir} and then add that package to the Copr chroot's additional packages list. This repo does that with copr-rpm-macros-x86-64-v3.

With that package installed in the buildroot, packages that honor Fedora's standard %optflags / %set_build_flags path will compile with -march=x86-64-v3 on Copr builders.

Local validation

Generate the macro SRPM:

make -f .copr/Makefile srpm outdir=dist-srpms spec=packaging/copr-rpm-macros-x86-64-v3.spec

Refresh the local Fedora packaging snapshots:

python3 ci/prefetch-fedora-specs.py

Generate a package SRPM the same way Copr will:

make -f .copr/Makefile srpm outdir=dist-srpms spec=konsole

Copr setup

1. Create or reuse a Copr project with the fedora-43-x86_64 chroot enabled.
2. Sync this repository's SCM package definitions into that project:

python3 ci/sync-copr-packages.py \
  --project yourname/kde-x86-64-v3 \
  --clone-url https://github.com/<owner>/<repo>.git \
  --commit <git-ref> \
  --submit-macro-build

3. After the macro package build succeeds, queue the package builds:

python3 ci/sync-copr-packages.py \
  --project yourname/kde-x86-64-v3 \
  --clone-url https://github.com/<owner>/<repo>.git \
  --commit <git-ref> \
  --submit-package-builds \
  --nowait-package-builds

The sync step also sets the Copr chroot's additional packages list to copr-rpm-macros-x86-64-v3, which is the piece that makes the x86-64-v3 compile target apply on Copr builders.
