[PATCH 0/9] fstests: few updates

[PATCH 0/9] fstests: few updates

[Luis R. Rodriguez]

I've deployed fstests on a relatively new system and ran into a few setup
snags which can be fixed easily. Other than this I also ran into a few
issues running a few tests which can easily also be fixed.

I've added a few new groups to help avoiding running tests with a basic
section. Some of these tests are better designed to be run with a custom
section and grouping them up helps with this.

[PATCH 1/9] generic/381: use username fsgqa-381

[Luis R. Rodriguez]

Some systems are not allowing usernames prefixed with a number now.
One can however use numbers as a postfix so use that.

[PATCH 4/9] build: update AC_PACKAGE_WANT_GDBM() and src/dbtest.c to build

[Luis R. Rodriguez]

Modern gdbm-devel packages bundle together gdbm.h and ndbm.h.
The old m4 macro had detection support for some old gdbm libraries
but not for new ones.

We fix compilation of src/dbtest.c by making the autoconf helper
check for this new arrangement:

If both gdbm.h and gdbm.h are found define set both gdbm_ndbm_=true,
and have_db=true, and define HAVE_GDBM_H. The src/dbtest.c already
had a HAVE_GDBM_H but there was never a respective autoconf settter for
it. We can just re-use this and fix it for new arrangement.

I'd suggest using the username "fsgqa2" so that other tests that want
to use a second username can do so using a more logically name username.

     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This isn't a "test names with digits" test, but "test names begining
with digits" test.  Changing the username to not begin with digits
invalidates the entire purpose of the test which is to ensure that
xfs_quota can differentiate between UIDs and names beginning with
numbers....

So from that perspective, NAK.

IF there are distros not allowing usernames to start with digits,
then this test needs a _requires check and to _notrun on those
systems.

Cheers,

Dave.

These should notrun automatically if you don't have an external log
device configured. Every test should either work with an external
logdev or explicitly notrun them, so I'm not sure what you're trying
to acheive here....

This change also looks wrong because:

xfs/044  [not run] This test requires a valid $SCRATCH_LOGDEV
xfs/045 1s ... 1s

xfs/044 is the external logdev test, and xfs/045 is a
duplicate uuid mount test that has nothign to do with external
log devices.

And, FWIW, we already have a "log" group to indicate tests that
exercise the log, and that mostly includes all the tests that use
external logs. It would be better to tag all the tests that exercise
the log with "log" rather than create some new group that doesn't
really provide any added benefit....

Cheers,

Dave.

NAK. this should be automatically detected by the tests and they
_not_run when support is not available.

This already _not_runs on new systems. we do not want to be adding
one-off group descriptors to avoid tests like this - the tests
themselves already detect whether they should run or not.

xfs/096 2s ... [not run] Requires older mkfs without strict input checks: the last supported version of xfsprogs is 4.5.

Why are you trying to add groups to define tests that not_run
correctly on systems they aren't supported on?

The way I'm splitting up tests is one first run with a basic xfs section
on a configuration file, with no external log, which pretty much runs all
tests but excludes all which require external or funky configurations.

A secondary pass then goes through these extra groups and then runs tests
only for the previously excluded groups but with their own respective
section. So for instance in this case I have:

[xfs]
....
[logdev_xfs]
...

Automatic detection if the requirements are met is fine, but this doesn't 
let me easily use say:

	./check -s logdev_xfs -g logdev

So for my case would one better goal be to just run check without the external
one and one with the external log?

  ./check -s xfs -g log
  ./check -s logdev_xfs -g log

Which seems to me like a misguided attempt to optimise test
runtimes. i.e. this doesn't provide test coverage of external log
behaviour in all the cases that need to be tested.

Data integrity code paths are affected by having an external log. IO
ordering changes with external logs, which can expose update/crash
recovery problems. external logs can expose data IO race conditions
that are masked by interleaved log IO. etc, etc, etc.

You can't just run an internal log test then add couple of extra
external log tests and say "external logs work fine".

You can do that if we ignore the fact that a large number of tests
need to be run on both internal and external log devices to cover
the differences in behaviour between them.

See above. Your test coverage assumptions are wrong, so what you are
trying to do really doesn't tell you whether external logs work
correctly or not. It's worse that not testing external logs at all,
because it gives the false impression that they have been
exhaustively tested and work just fine when that really isn't the
case.

This looks fine to me.

The only system I have by hand that have both <gdbm.h> and <ndbm.h> but
not any <gdbm/[gn]dbm.h> is openSUSE Tumbleweed. Without this patch,
dbtest was not built on openSUSE, and was built successfully with this
patch applied. And dbtest is still built on RHEL6/7 and Fedora.

BTW, I'll queue patch 3 and this patch for next fstests release, while
other patches seem not necessary, I agreed with Dave that groups are not
for excluding tests, the required tools and environments should be
detected by tests and _notrun if not met. (The README change looks fine,
but it doesn't apply due to the "fsgqa-381" change, so I drop it too for
now.)

Indeed, openSUSE and SLE releases.

Yeap.

Feel free to modify the commit log accordingly then. Curious, what packages
does Fedora/ RHEL6/7 use for the requirement here?

We just have one:

$ rpm -ql gdbm-devel-1.12-1.282.x86_64
/usr/bin/gdbm_dump
/usr/bin/gdbm_load
/usr/bin/gdbmtool
/usr/include/dbm.h
/usr/include/gdbm.h
/usr/include/ndbm.h
/usr/lib64/libgdbm.a
/usr/lib64/libgdbm.so
/usr/lib64/libgdbm_compat.a
/usr/lib64/libgdbm_compat.so
/usr/lib64/libndbm.a

I think patch 2 is fine too.

Yeah makes sense now. I think we should also document when adding
a group makes sense as well.

gdbm-devel too, but it has gdbm/[gn]dbm.h pointing to ../[gn]dbm.h, so
there's no such problem and dbtest is building normally.

# rpm -ql gdbm-devel
/usr/include/dbm.h
/usr/include/gdbm
/usr/include/gdbm.h
/usr/include/gdbm/dbm.h
/usr/include/gdbm/gdbm.h

Hi guys -

This change breaks on older releases like SLES 11 where both <ndbm.h>
and <gdbm.h> define datum, so we get build failures.  The failure is
new, but not because it used to pass and now doesn't.  It's apparently
never built on SLES releases since we ship /usr/include/ndbm.h and then
we notrun the test that uses.  Now that we're looking for gdbm.h and
find it, we attempt to build src/dbtest and fail.

This fix isn't the right solution.  The problem is that we have a couple
layers of old cruft that needs to be cleaned out.

1) As Luis notes, nothing sets HAVE_GDBM_H.  The thing is that there is
no version of gdbm.h that exports the NDBM interface.  Further, looking
at the git history, nothing has ever set HAVE_GDBM_H.  It was dead code
when it was committed initially as best I can tell.
2) openSUSE Tumbleweed doesn't need <gdbm.h> at all.  It needs <ndbm.h>
and this fix works because Luis added it to the HAVE_GDBM_H stanza.
3) AC_PACKAGE_WANT_NDBM used to check for <ndbm.h> but it was a check
for IRIX and the caller was removed ages ago.  It wouldn't matter if it
were called anyway since libndbm is an IRIX library.  Linux, IIRC, has
never shipped a libndbm.

I'll post a few patches following this to clean it up and get it working
on SLES11.
