[Patch v6 10/14] devel: add script to generate test databases

From: Jani Nikula <jani at nikula.org>

Add script to generate notmuch test databases using specified versions
of notmuch. This is useful for generating material for database
upgrade tests.

This reuses the test infrastructure to have a sandbox environment for
notmuch new etc.

+#
+# NAME
+#	gen-testdb.sh - generate test databases
+#
+# SYNOPSIS
+#	gen-testdb.sh -v NOTMUCH-VERSION [-c CORPUS-PATH] [-s TAR-SUFFIX]
+#
+# DESCRIPTION
+#	Generate a tarball containing the specified test corpus and
+#	the corresponding notmuch database, indexed using a specific
+#	version of notmuch, resulting in a specific version of the
+#	database.
+#
+#	The specific version of notmuch will be built on the fly.
+#	Therefore the script must be run within a git repository to be
+#	able to build the old versions of notmuch.
+#
+#	This script reuses the test infrastructure, and the script
+#	must be run from within the test directory.
+#
+#	The output tarballs, named database-<TAR-SUFFIX>.tar.gz, are
+#	placed in the test/test-databases directory.
+#
+# OPTIONS
+#	-v NOTMUCH-VERSION
+#		Notmuch version in terms of a git tag or commit to use
+#		for generating the database. Required.
+#
+#	-c CORPUS-PATH
+#		Path to a corpus to use for generating the
+#		database. Due to CWD changes within the test
+#		infrastructure, use absolute paths. Defaults to the
+#		test corpus.
+#
+#	-s TAR-SUFFIX
+#		Suffix for the tarball basename. Empty by default.
+#
+# EXAMPLE
+#
+#	Generate a database indexed with notmuch 0.17. Use the default
+#	test corpus. Name the tarball database-v1.tar.gz to reflect
+#	the fact that notmuch 0.17 used database version 1.
+#
+#	$ cd test
+#	$ ../devel/gen-testdb.sh -v 0.17 -s v1
+#
+# CAVEATS
+#	Test infrastructure options won't work.
+#
+#	Any existing databases with the same name will be overwritten.
+#
+#	It may not be possible to build old versions of notmuch with
+#	the set of dependencies that satisfy building the current
+#	version of notmuch.
