# Unit test: packages/apps/clickhouse/hack/update-versions.sh (the ClickHouse
# version-map generator).
#
# The generator turns the Docker Hub tag lists of clickhouse/clickhouse-server
# and clickhouse/clickhouse-keeper into files/versions.yaml (a major -> full
# tag map) and rewrites the version enum in values.yaml. These properties are
# load-bearing and each guards a specific failure the review of #3476 caught:
#
#   1. The server/keeper tag intersection must be computed with a byte
#      (lexicographic) collation, not a version collation. `comm` walks its
#      inputs assuming byte order; feeding it `sort -V` output silently drops
#      common tags at every X.9 -> X.10 boundary.
#   2. The default line is frozen to the exact tag it already ships (read from
#      the committed versions.yaml) so a regeneration never bumps the image of
#      existing default-version installs. The freeze follows whichever major is
#      the default, not a hardcoded one.
#   3. Dropping the current default's major from the supported set is a hard
#      error, not a silent promotion of the newest major to default.
#   4. A configured major with no tag common to both images is a hard error,
#      and the generator is atomic: on any error the committed files are left
#      untouched.
#   5. The values.yaml splice is bounded: a malformed section (enum header
#      present, `version:` line absent) does not swallow the rest of the file.
#
# The generator is exercised offline: CH_SERVER_TAGS_FILE / CH_KEEPER_TAGS_FILE
# inject the tag lists (no curl), and VALUES_FILE / VERSIONS_FILE stay in a
# scratch dir. It remains compatible with the legacy hack/cozytest.sh
# translator, so it avoids `run`/`$status`/`$lines`, file-local setup/teardown,
# and a standalone `}` inside a test body. Each assertion exits non-zero on
# failure and the body relies on `set -e`.
