# getversion — determine the project version for packaging and diagnostics
# -----------------------------------------------------------------------------
#
# This script computes a version string using the following logic:
#
# 1. Extract the base PACKAGE_VERSION from the `configure` script.
#
# 2. If running inside a Git repository and `git describe` is usable:
#
# a. If the current commit matches an annotated tag exactly:
# VERSION = <tag>
# e.g., VERSION = 2.0.0+RC1
#
# b. If the current commit is ahead of a tag:
# VERSION = <PACKAGE_VERSION>+dev.<N>.g<commit>
# e.g., VERSION = 2.0.1-devel+dev.3.gabcd123
#
# 3. If *not* in a Git repo but a `VERSION` file exists:
#
# a. If the file contains a line like "<version> build <build_number>", both values are extracted.
#
# b. Otherwise, the VERSION is read from the file and the BUILDNUMBER is taken from BUILD_NUMBER if it exists.
#
# (This is the case for Apache Cloudberry packaging builds, where these files are created by the
# release script and may also be leveraged by downstream users.)
#
# 4. If neither a Git repo nor a VERSION file is present:
# VERSION = <PACKAGE_VERSION> from configure
# BUILDNUMBER = dev
#
# 5. If a BUILD_NUMBER file is present and BUILDNUMBER is "dev", it will override the default:
# BUILDNUMBER = $(cat BUILD_NUMBER)
#
# Output:
# - Default: <version> build <build_number>
# - With --short: just <version>
#
# Examples:
# ./getversion
# → 2.0.1-devel+dev.3.gabcd123 build dev
#
# ./getversion --short
# → 2.0.1-devel+dev.3.gabcd123
#
# (On exact tag)
# → 2.0.0+RC1 build dev
#
# Supported Features:
# - Handles annotated tags with special characters like `+` or `-`
# - Produces semver-compatible version strings for CI/CD
# - Works with or without Git
#
# Intended for use in:
# - Release packaging
# - Diagnostic reporting
# - Embedding traceable version info into builds
