[PATCH 0/3] Adapt some tests to ChromeOS

[PATCH 0/3] Adapt some tests to ChromeOS

[Gwendal Grignou]

When running xfstests on ChromeOS, some were failing for spurious
reasons:
- getconf not present on the test system because glibc is not installed.
- ftruncate want to allocate a file bigger than the partition.
- Attribute selinux.security in the way of testing xattr.

Gwendal Grignou (3):
  generic: workaround device where glibc is not installed
  ext4: 032: fail nicely if the test partition is not big enough for the
    test
  generic: exclude selinux xattr form being considered

[PATCH 1/3] generic: workaround device where glibc is not installed

[Gwendal Grignou]

Some tests needs page size and long size, provided by getconf.
On systems where getconf is not installed, guess with default values.

The GETCONF (or GETCONF_PROG is prefered) definition belongs to
common/config along with other FOO_PROG definitions.

The functions should go to common/rc file.

But I think we could just use "$here/src/feature -s" to get page size in
get_page_size() and "$here/src/feature -w" to get bits per long. But we
need to add

_require_test_program "feature"

to all tests that call get_page_size()/get_long_bit().

And maybe we could rename get_page_size to _get_page_size while we're at
it (perhaps in a separate patch), as it's a global helper function not a
local one.

Thanks,
Eryu

This doesn't look right to me. We can safely truncate to a very large
file size even if the size is bigger than the free space, it's just a
typical sparse file.

I guess the problem is that your SCRATCH_DEV is too small to hold the
post-resize fs image.

Thanks,

I didn't see such failures before, could you please provide more info in
the commit log about the problem? So I can try to reproduce the failure.

This doesn't belong to _filter_scratch but to filters that filter xattr.
I want to understand & reproduce the problem so I know where the failure
comes from and think about what the best fix would be.

IMO, that is unnecessary. `feature` is test harness infrastructure,
like common/rc and check.  If the feature binary does not build then
the test harness is running on a broken platform. IOWs, we shouldn't
be requiring functionality tests for core infrastructure - if the
core infrastructure didn't build, then there's bigger problems that
need to be fixed...

Cheers,

Dave.

Makes sense. Then it'd be better to require it explicitly in
common/config as what we did to fsstress and xfs_io etc.

Thanks,
