* [PATCH] generic/062: filter redundant output by getfattr

When getfattr dumps values of all extended attributes (-d option),
it doesn't print empty extended attributes. e.g: user.name. But
from attr-2.4.48 this behavior is changed,  new getfattr prints
user.name="".

The {=""} will break the golden image, so filter the redundant =""
at the end if it has.

Hi,

This's a bad news. Latest attr package attr-2.4.48 changed his
behavior as above. And this's different with attr-2.4.47.

With old attr:
# setfattr -h -n user.name testfile
# getfattr -d -n user.name testfile                                                                                                                                     
# file: testfile                               
user.name

With new attr:
# setfattr -h -n user.name testfile
# getfattr -d -n user.name testfile                                                                                                                                     
# file: testfile                               
user.name=""

Note: -d option is necessary

This little difference will break golden image. So this's the problem.
If you have better idea than this patch, please tell me.

Thanks,
Zorro

This should really be done by a new helper function that hides all the
details, so future tests could just take use of the helper.

Thanks,

OK. So how about a common function named _getfattr in common/attr, to instead
of all $GETFATTR_PROG (or just g/062).

Or a a common function named _filter_getfattr, to filter some $GETFATTR_PROG
output if a case need it.

_getfattr()
{
	$GETFATTR_PROG $@ 2>&1 | _filter_testdir_and_scratch | \
		sed -e 's/=\"\"//'
}

Or

_filter_getfattr()
{
	_filter_testdir_and_scratch | sed -e 's/=\"\"//'
}

_getfattr() is fine, converting all existing bare getfattr calls would
be good.
