# Decide whether the just-built release VERSION should also move the Docker
|
||
# `:latest` / `:latest-web` tags.
|
||
#
|
||
# Promote ONLY when VERSION is the highest STABLE semver among the union of
|
||
# {existing git tags} ∪ {VERSION}. Folding VERSION into the candidate set makes
|
||
# the decision independent of git-tag sync timing: on a `release: released`
|
||
# event the freshly-created tag is often not yet visible to `git fetch --tags`
|
||
# when this job runs, so a candidate set built purely from `git tag -l` would
|
||
# resolve HIGHEST to the *previous* version and skip the `:latest` promotion —
|
||
# leaving `latest` one release behind (#5301).
|
||
#
|
||
# Usage:
|
||
# git tag -l 'v[0-9]*' | sed 's/^v//' | scripts/ci/should-promote-latest.sh "$VERSION"
|
||
#
|
||
# - $1 : the version being published (no leading `v`, e.g. 3.8.40).
|
||
# - stdin : newline-separated candidate tags (a leading `v` is stripped;
|
||
# pre-release tags — anything containing `-`, e.g. 3.9.0-rc.1 —
|
||
# are ignored). May be empty (first release).
|
||
# Prints "true" if VERSION should move :latest, "false" otherwise.
