#
# Synopsis
# --------
#
# This script performs a build of RPM packages from a given .spec file in
# controlled environment to guarantee consistent results when building RPMs
# different machines. It uses a separate file rpmbuild-bot-env.sh located
# in the same directory to set up the environment and control the build
# process. The main purpose of this script is to build RPM packages for a
# specific distribution channel maintaining distribution-specific rules.
#
# Usage
# -----
#
# > rpmbuild-bot.sh SPEC[=VERSION]
# >                 [ upload[=REPO] | test[=MODE] | clean[=test] |
# >                   move[=FROM_REPO=TO_REPO] | remove[=REPO] ]
# >                 [-f]
#
# MYAPP is the name of the RPM package spec file (extension is optional,
# .spec is assumed). The spec file is searched in the SPECS directory of the
# rpmbuild tree (usually $USER/rpmbuild/SPECS, rpmbuild --eval='%_specdir'
# will show the exact location). This may be overridden by giving a spec file
# with a path specification.
#
# The second argument defines the command to perform. The default command is
# "build". The following sections will describe each command.
#
# Building packages
# -----------------
#
# The "build" is the main command which is used to generate packages for
# distribution. This command does the following:
#
# 1. Build all RPM packages for all architectures specified in
#    $RPMBUILD_BOT_ARCH_LIST. The packages are stored in the RPMS
#    directory of the rpmbuild tree.
# 2. Build the source RPM. Stored in the SRPMS directory.
# 3. Create a ZIP package from the RPMs for the architecture specified
#    last in $RPMBUILD_BOT_ARCH_LIST.
#
# The build process for each architecture is stored in a log file in the logs
# directory of the rpmbuild tree (`rpmbuild --eval='%_topdir'/logs`). Creation
# of the source RPM and ZIP files is also logged, into separate log files.
#
# The "build" command will fail if the log directory contains files from a
# successful run of another "build" command for this package. This is to
# prevent overwriting successfully built packages that are not yet uploaded to
# the distribution repository (see the "upload" command). You should either
# run the "upload" command or use the -f option to force removal of these
# log files and the corresponding package files if you are absolutely sure they
# should be discarded.
#
# The "build" command will also check if there is a directory named SPEC in the
# same directory where the given .spec file resides. If such a directory
# exists, all files in it are assumed to be auxiliary source files used by the
# .spec file via SourceN: directives. These files will be automatically copied
# to the SOURCES directory in the rpmbuild tree before starting the build
# process.
#
# Doing test builds
# -----------------
#
# The "test" command is used to build packages for one architecture for testing
# purposes. In this more, neither the source RPM nor the ZIP file is created.
# Also, a special option is automatically passed to rpmbuild to clear the %dist
# variable to indicate that this is a local, non-distribution build. Such
# packages will always be "older" than the corresponding builds with %dist
# so that they will be automatically updated on the next yum update to the
# %dist ones. The packages built in "test" mode are NOT intended for
# distribution, they are meant only for local testing before performing the
# full build of everything.
#
# It is possible to configure which steps of the build to perform using the MODE
# parameter to the "test" command which may take one of the following values:
#
#   prep    Execute the %prep section of the spec file only.
#   build   Execute the %build section only (requires %prep to be executed
#           before). May be run multiple times.
#   install Execute the %install section only (requires "prep" and "build"
#           to be executed before). May be run multiple times.
#   pack    Create the RPM packages (requires "prep", "build" and "install"
#           to be executed before). Note that this step will also execute
#           the %clean section so that a new "install" execution is
#           necessary for "pack" to succeed.
#
# When no MODE parameter is given, all steps are executed in a proper order.
#
# The results of the "test" command are stored in a log file in the logs/test
# directory of the rpmbuild tree. The previous log file, if any, is given a .bak
# extension (the previous .bak file will be deleted).
#
# The "test" command will copy auxiliary source files for the .spec file, if any,
# to the proper location before rpmbuild execution -- the same way the "build"
# command does it.
#
# Uploading packages
# ------------------
#
# The "upload" command will upload the packages built with the "build"
# command to the official distribution channel configured in
# rpmbuild-bot-env.sh. The REPO parameter specifies one of the configured
# repositories. When REPO is not given, the default repository is used
# (usually experimental or similar).
#
# The upload command also requires the spec file to be under SVN version control
# and will try to commit it after uploading the RPMs to the repository with the
# automatic commit message that says "spec: PROJECT: Release version VERSION."
# (where PROJECT is the spec file name and VERSION is the full version,
# excluding the distribution mark, as specified by the spec file).This to ensure
# that the spec file is published at the same time the RPMs are published - to
# guarantee their consistency and simplify further maintenance. Note that the
# auxiliary source directory named SPEC and located near the spec file (see the
# "build" command), if it exists, will also be committed. If the spec file is
# not under version control, the "upload" command will fail.
#
# Note that the "upload" command needs log files from the "build" command
# and will fail otherwise.
#
# Upon successful completion, the "upload" command will remove all uploaded
# RPM and ZIP packages and will move all "build" log files to logs/archive.
#
# Cleaning packages
# -----------------
#
# The "clean" command will delete packages built with the "build" command
# and their log files without uploading them to a repository. This is useful
# when the successful build needs to be canceled for some reason (wrong source
# tree state, wrong patches etc.). Note that normally you don't need to use
# this command; it's an emergency-only tool.
#
# The "clean" command needs log files from the "build" command and will fail
# otherwise.
#
# If the "clean" command is given a "test" parameter, it will clean up the
# results of the "test" command instead of "build". The log file from the
# "test" command needs to be present or the command will fail.
#
# Moving packages between repositories
# ------------------------------------
#
# The "move" command allows to move a particular version of the packages
# built with the "build" command and uploaded with the "upload" command from one
# repository to another one. The "move" command is normally used to move
# packages from a test repository to a production one when they are ready for
# wide distribution.
#
# The "move" command needs log files from the "build" and "upload" commands
# and will fail otherwise. It also requires the VERSION parameter for the SPEC
# argument to be given (to specify the version of the packages to remove) and
# requires the FROM_REPO=TO_REPO parameter itself to specify the source
# repository and the target repository, respectively.
#
# The log files from the "build" and "upload" commands are not removed by the
# "move" command so it may be performed multiple times. The current location
# of the packages is not tracked in the log files so the command will fail
# if the source repository doesn't have the package files or if the target
# repository already has them.
#
# Removing packages
# -----------------
#
# The "remove" command allows to remove a particular version of the packages
# built with the "build" command and uploaded with the "upload" command from a
# repository. This is useful when the successful build needs to be canceled for
# some reason (wrong source tree state, wrong patches etc.). Note that normally
# you don't need to use this command; it's an emergency-only tool.
#
# The "remove" command needs log files from the "build" and "upload" commands
# and will fail otherwise. It also requires the VERSION parameter for the SPEC
# argument to be given (to specify the version of the packages to remove) and
# accepts the REPO parameter itself just like the "upload" command does (to
# specify a repository to remove the packages from).
#
# Note that the log files from the "build" and "upload" commands are also
# removed by this command upon successful package removal.
#
# Return value
# ------------
#
# The rpmbuild-bot.sh script will return a zero exit code upon successful
# completion and non-zero otherwise. The script output and log files should be
# inspected to check for a reason of the failure.
