[PATCH 0/4] nfs-utils: add testing infrastructure to nfs-utils (try #6)

[PATCH 0/4] nfs-utils: add testing infrastructure to nfs-utils (try #6)

[Jeff Layton]

This is an updated patchset for adding test infrastructure to nfs-utils.
The main differences in this patchset are:

1) some bugfixes in the statdb_dump program

2) an extra check for root privs in the t0001 test. If the caller
doesn't have root privs, then the test is skipped

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 be fairly simple
to do.

[PATCH 2/4] nfs-utils: introduce new statd testing simulator

[Jeff Layton]

rpc.statd is often prone to subtle, difficult to detect breakage. When
it has problems, they're often invisible and only manifest themselves
as failed lock recovery.

This program is intended to function as part of a test harness for
statd. It's a multicall binary that serves as a synthetic NSM client
program, and a daemon that can simulate lockd for purposes of testing
the NSM to NLM downcall.

A new top level "tests/" directory is also added to nfs-utils to start
as a repository for automated tests of nfs-utils components.

[PATCH 4/4] nfs-utils: add initial tests for statd that run via "make check"

[Jeff Layton]

Leverage the support that automake already has for running tests via
make check. Add a simple test that just checks that the statd mon and
unmon calls actually work.

Adding more tests should be a simple matter of adding new scripts
exit 0 on success and non-zero on fail, and adding those to the
Makefile.am.

Basically what this tells me is that you can't runs these tests at all  
if your development tree lives on an NFSv2/3 mount point.

Is --no-notify really needed?  I guess that's just a safety net.

I don't think the test I have so far will do any fcntl locking, so that
one would probably work. No guarantees on any that are added later though.

It's probably best to assume that doing so would be problematic.

Yeah. On the off chance that someone has monitored hosts in the db
after shutting down statd, I don't think we want to start spraying
notifications when we start the test.

Personally what I'll do is run this on a kvm guest or otherwise
dedicated test machine.  So I can live with that assumption.

statd/sm-notify are supposed to be smart enough to send reboot  
notifications once per reboot anyway.  But it can't hurt to enforce it  
here.
