This document contains a collection of notes specific to the import of the NetBSD test suite into head. These notes are built on the instructions in the FreeBSD Subversion Primer that detail how to deal with vendor branches and you are supposed to follow those: http://www.freebsd.org/doc/en/articles/committers-guide/subversion-primer.html The NetBSD test source code was originally obtained via NetBSD anoncvs as described in the NetBSD handbook: http://www.netbsd.org/docs/guide/en/chap-fetch.html#chap-fetch-cvs and is imported into the NetBSD/tests vendor branch (see base/vendor/NetBSD/tests/). The process used to bootstrap the vendor tree was similar to the following: /bin/sh export CVSROOT="anoncvs@anoncvs.NetBSD.org:/cvsroot" cvs -z9 co -D "09/30/2014 20:45" -P src/tests mv src/tests/* tests/dist/. Please adjust the checkout date spec (the argument passed via -D) to match the desired checkout time. To merge the vendor branch into head do something like this: cd .../base/head/contrib/netbsd-tests svn merge --accept=postpone \ svn+ssh://svn.freebsd.org/base/vendor/NetBSD/tests/dist . find . -name Makefile\* | xargs svn rm --force and resolve any conflicts that may arise at this point. Lastly, with the list of old and new files in this import, make sure to update the reachover Makefiles accordingly.
