# check_compatibility.sh
# A script that uses the Java API Compliance Checker (Java ACC) to gauge the binary and source
# compatibility of two arbitrary versions of Apache HBase.
#
# Special thanks to Andrey Ponomarenko, the leader of the Java ACC project, for introducing
# support for class annotation filtering into the tool at our request.
#
# Usage: This script checks out two versions of HBase (via a tag, branch, or commit hash in Git),
# builds the releases, and generates XML descriptors of relevant JARs (i.e. excluding
# test JARs, as well as external HBase dependencies). Next, the Java API Compliance
# Checker (http://ispras.linuxbase.org/index.php/Java_API_Compliance_Checker) is
# downloaded and run using these XML descriptor files to generate a report
# of the degree of binary and source compatibility of the two HBase versions. Finally,
# the resulting report is scraped and some of its results output to stdout.
#
# Note that GNU getopt is required for this script to work properly. If you're running
# a different variant (e.g. OS X ships with BSD getopt), you need to get the GNU variant
# and either put it on the PATH or set GETOPT to the location of GNU getopt before
# executing this script.
#
# Example: To compare the binary and source compatibility of the 0.98.6 release and the
# tip of the master branch:
# $ ./check_compatibility.sh 0.98.6
# (i.e. if -b is omitted, a check is implicitly run against master).
#
# To compare the binary and source compatibility of the HBase 0.98.5 and 0.98.6
# releases:
# $ ./check_compatibility.sh 0.98.5 0.98.6

check_compatibility.sh
A script that uses the Java API Compliance Checker to gauge the binary and source
compatibility of two arbitrary versions of Apache HBase.
Usage: [<options>] <ref1> [<ref2>]
The positional arguments are Git references; this can be a tag (e.g. 0.98.6),
a branch (e.g. 0.98), or a particular commit hash. If ref2 is omitted, master
will be used.
Options:
-b, --binary-only Only run the check for binary compatibility.
-f, --force-download Download dependencies (i.e. Java ACC), even if they are
already present.
-h, --help Show this screen.
-n, --no-checkout Run the tool without first using Git to checkout the two
HBase versions. If this option is selected,
dev-support/target/compatibility/1 and
dev-support/target compatibility/2 must each be Git repositories.
Also note that the references must still be specified as these are
used when naming the compatibility report.
-o <opts>, --options=<opts> A comma-separated list of options to pass directly to Java ACC.
-q, --quick Runs Java ACC in quick analysis mode, which disables a
number of checks for things that may break compatibility.
-r <url>, --repo=<url> URL of the HBase Git repository to use. Defaults to Apache
HBase's GitHub (https://github.com/apache/hbase.git).
-s, --source-only Only run the check for source compatibility.
