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.
