# This script nowadays (that's why it exists as such simple and
|
|
# short script at all) just appends "+0" to the specified
|
|
# <version_number> on the command line.
|
|
#
|
|
# This turned out to be the most reliable way to get:
|
|
#
|
|
# $existing_old_version < $snapshot_version < $new_version
|
|
#
|
|
# where $existing_old_version is the provided <version_number>,
|
|
# $snapshot_version is a version number based on the output of
|
|
# the script (as used inside scripts like
|
|
# jdg-generate-{git,svn}-snapshot) and $new_version is a version
|
|
# number that might show up in the future.
|
|
#
|
|
# NOTE: The author of jenkins-debian-glue is aware of only one
|
|
# exception where this isn't true with +0 appended for $snapshot.
|
|
# This would be the case when e.g. version 1.2.3 would be changed
|
|
# to 1.2.3-1. But this would mean a change in Debian packaging as
|
|
# well (from Debian package source being identical to the
|
|
# pristine source (AKA native package) vs. upstream software
|
|
# packaged within Debian (AKA non-native package)). In such a
|
|
# situation the $existing_old_version should be raised from e.g.
|
|
# 1.2.3 to at least 1.2.3.1-1, otherwise the generated
|
|
# $snapshot_version will be older than $existing_old_version
|
|
# until it's 1.2.4, 1.3, etc.
