#!/bin/bash
# Update GSA Ubuntu Repositories or create a local repository
#
# Author: Leonardo Tonetto (tonetto@linux.vnet.ibm.com)
# Revisor: Arif Ali (aali@ocf.co.uk)
#
#
# Getting Started:
#  - Clone the xcat-core git repository under a directory named "xcat-core/src"
#  - make sure reprepro is installed on the build machine
#  - Run this script from the local git repository you just created.
#       ./build-ubunturepo -c BUILDALL=1

# Usage:  attr=value attr=value ... ./build-ubunturepo { -c | -d }
#               PROMOTE=1 - if the attribute "PROMOTE" is specified, means an official dot release.  This does not
#                           actually build xcat, just uploads the most recent snap build to http://xcat.org/files/xcat/ .
#                           If not specified, a snap build is assumed, which uploads to https://xcat.org/files/xcat/
#               PREGA=1 - use this option with PROMOTE=1 on a branch that already has a released dot release, but this
#                           build is a GA candidate build, not to be released yet.  This will result in the tarball
#                           being uploaded to http://xcat.org/files/xcat/repos/apt
#                           (but the tarball file name will be like a released tarball, not a snap build).
#                           When you are ready to release this build, use PROMOTE=1 without PREGA
#               BUILDALL=1 - build all rpms, whether they changed or not.  Should be used for snap builds that are in
#                            prep for a release.
#               GPGSIGN=0 -  Do not sign the repo in the end of the build. The repo will be signed by default
#
#               LOG=<filename> - provide an LOG file option to redirect some output into log file
#
#               DEST=<directory> - provide a directory to contains the build result
#
# For the dependency packages 1. All the xcat dependency deb packages should be uploaded to
#                                "pokgsa/projects/x/xcat/build/ubuntu/xcat-dep/debs/" on GSA
#                             2. run ./build-ubunturepo -d
#
#                             3. the built xcat-dep deb packages tarball can be found in "../../xcat-dep"
#                                related to the path of this script
