This is an updated patchset for adding test infrastructure to nfs-utils. The main differences from the last patchset are: 1) renamed "statdtest" to "nsm_client", since that's a bit more descriptive of its actual purpose. 2) added a very simple "statdb_dump" program that dumps out the more interesting fields of the of the NSM monitor DB. The inital mon/unmon test now uses that program to verify the contents of the DB after the MON call. This patchset is intended as a starting point for an automated test suite for nfs-utils. The idea here is to start simply and add a suite of tests that we can run via "make check" -- the standard automake method for running tests. Clearly there are limits to what we can test without a multi-host test harness. My hope is that this should help keep us from breaking basic functionality by allowing us to test it in a very simple fashion. At some point in the future we should also consider how to best handle multi-machine testing, but I see that as complimenting this code rather than replacing it. For this set, the focus is on testing statd, which is particularly susceptible to subtle breakage. Problems with it are often not noticed until lock recovery breaks, and that may greatly lag the actual breakage. To faciitate statd testing, I've added a "nsm_client" program that can serve as a synthetic statd client and an NLM simulator. It's very loosely based on the old statd simulator code. That program is dependent on some of Chuck Lever's recent statd patches -- notably the ones that break out common NSM code into libnsm.a. For this initial drop, I'm just adding a single test that tests mon and unmon functionality with statd. Adding more tests should fairly simple to do.
