# Purpose
|
|
# The purpose of this script is to facilitate auto-tagging of
|
|
# Jira tickets with fix-versions. There are two tricky parts to auto-tagging:
|
|
#
|
|
# 1. Given a change set (PR diff), what constitutes a change to a service?
|
|
# 2. Given you've determined a set of files has changed a service, which service was changed?
|
|
#
|
|
# As this repository is a single-service repository, there is no concern with number 2 above.
|
|
#
|
|
# This script endeavors to answer question number one - which files constitute a change to a service
|
|
# Given an input file which is the git diff from a PR
|
|
# this script should determine what file changes in the diff
|
|
# constitute a material change to a service. At the time
|
|
# of this writing, this currently only identifies java and go
|
|
# files, and if those files are in the change list, then those
|
|
# file names are returned in the output file.
|
|
#
|
|
# Inputs
|
|
# $1 - the git diff from the pull request
|
|
# $2 - the output file which should ultimately contain file names from the diff that affect a service
|
|
