build-ubunturepo was 710 lines of shell doing the Debian half of what
buildrpms.pl does for rpms, with no code in common and a different CLI. It also
carried paths that are dead: GSA uploads, the PROMOTE/PREGA release flows, and a
-d mode that built an xcat-dep repository from a different project's packages.
builddebs.pl replaces it and mirrors buildrpms.pl -- Getopt::Long options, one
package list, build then index then sign -- so the two builders read the same way
and share BuildUtils.pm.
The design rests on one fact: xcat-core debs are Perl. They are byte-identical
for every Ubuntu release, so they are built ONCE and the same files are published
into every codename. Only xCAT, xCATsn and xCAT-genesis-scripts carry an
architecture, and there the difference is packaging metadata, not compiled
output. That is why this needs no sbuild and no per-codename chroot -- unlike
xcat-dep, whose packages are compiled and genuinely differ per release.
BuildUtils.pm holds what both builders need and what was worth making testable:
the Version-Release derivation from the commit time, the xCAT-probe helper
staging, the deb arch and dist tables, the debian/control version pinning, the
changelog rewrite, the reprepro conf generation, and the build lock. Every
function is pure or takes its side effect as an argument, so build_utils.t (45
assertions) drives each one rather than grepping a builder for evidence that it
is called. Verified by mutation: shrinking the arch table reddens 1, dropping
the /g from the control pin reddens 2.
The env-var CLI maps to options: BUILDALL=1 -> --force, GPGSIGN=1 -> --gpg-sign,
GPG_HOME -> --gpg-home, DEST -> --dest, DISTS -> --dist (repeatable). UP=0 has no
equivalent because uploading is gone -- the CD pipeline's deploy step publishes.
Callers updated: github_action_xcat_test.pl and travis.pl. The comment in
github_action_xcat_test.pl explaining why CI copies the tree before building is
corrected -- build-ubunturepo rm -rf'd $curdir/../../xcat-core, which under
GitHub's work/<repo>/<repo> layout is the checkout's own parent; builddebs.pl
writes under dist/debs inside the checkout and restores every file it edits, so
the copy is now only isolating the tests from build residue.
Two tests moved with it. build_ubunturepo_lock.t extracted the lock out of the
shell with a regex and ran that; the lock is now a function, so builddebs_lock.t
calls it -- and asserts what actually matters, that two builds of one checkout
fail fast while two builds of different checkouts run concurrently.
ubuntu_2604_pkglist.t asserted that resolute appeared in a shell fragment of
build-ubunturepo's source; it now asks BuildUtils for the release list and checks
a resolute stanza reaches conf/distributions. That assertion would have passed on
any file containing the fragment and broken on a reflow that changed nothing.
Verified: prove -r xCAT-test/unit fails on 6 files here against 7 on
upstream/master, the difference being apache_config_sources.t, fixed by the
preceding commit. The remaining 6 are missing DB modules on the machine that ran
it and are identical on both.
NOT done here, and required before this can merge: the Ubuntu core CD pipelines
still invoke ./build-ubunturepo (ci/ubuntu/Jenkinsfile.core-ubuntu-{devel,stable}
in VersatusHPC/xcat-core-ci-cd, and the inline script in each live Jenkins job).
Those must be switched to builddebs.pl in the same change window.

xCAT
xCAT is a toolkit for deployment and administration of clusters of all sizes.
The xCAT sunset was only a quick eclipse
Dear xCAT Community,
The xCAT sunset has changed course. VersatusHPC has been invited to join the xCAT Consortium, and future development will move toward direct upstream contributions coordinated with the Consortium and its existing member companies.
That matters most for Enterprise Linux 10 (EL10). EL10 support is coming to xCAT, restoring a future operating-system path for sites that still rely on xCAT. This is an important change from the previous sunset guidance, where the lack of an EL10 path was one of the strongest reasons to move away from xCAT.
The xCAT Consortium continues to recommend Confluent as the long-term successor to xCAT, and that remains the Consortium position. Users planning new cluster-management deployments should evaluate Confluent and its xCAT comparison documentation.
At the same time, xCAT is no longer sunsetted. The Consortium and participating companies will continue updating xCAT while there is community and user demand for it.
In summary:
- xCAT development is continuing upstream through the Consortium and participating companies.
- Enterprise Linux 10 support is coming.
- Confluent remains the Consortium-recommended successor and migration path.
- xCAT updates will continue while there is community and user demand.
We want to thank the xCAT Consortium and community for keeping this project moving. The sun went behind the moon for a moment, but xCAT is still here.

With thanks,
The xCAT Consortium
