[PATCH v1 0/1] Parent pointers test v1

[PATCH v1 0/1] Parent pointers test v1

[Allison Henderson]

Hi all,

This is the first revision of a new xfstest to exercise the parent
pointer code. The test cover basic parent pointer operations,
including link, unlink, rename, overwrite, hardlinks and
error inject.

As always, comments and feedback are appreciated.  Thank you!

It actually takes about a minute and a half for me, though I guess it 
would depend on how fast the host is.  Most of the time goes into the 
loop of 100: create a hard link, and then scan through all the entries 
to see if the new parent pointer is there.  This was mostly to make sure 
the attr tree was expanding correctly back when I was trying to get the 
transaction rolling straightened out.

That is still a bit surprising to me. I suspect the parent pointer parsing
code that invokes awk so many times may be the culprit. We soemtimes use
little C progs to assist in the test (see in src/) in cases where bash scripting
is insufficient or inefficient.

Perhaps if you use more bash array tricks instead of awk, parsing code
will be faster? assuming that parsing code is the slow down factor?

In any case, a "quick" test gets run more frequently by more people
so it would be a big benefit IMO if you are able to squeeze that test
runtime down to "quick".

Thanks,
Amir.

Sure, I'll see if I can optimize it a bit and get it running faster.  Thx!

I think it can come out.  I had used another test as a template and 
likely forgot to gut some things.  Will clean up.

Oh, I think we had discussed using protofiles in the test case a really 
long time ago.  This is just the first push of it because I cant really 
have a successful diff until all the bugs are worked out :-)

The code that constructs the protofile is another disjoint set of code 
that creates inodes.  So like any such similar code path, the parent 
pointers need to get added in there too.  This is effectively exercising 
the code changes seen in patch 25 of the xfsprogs set.

I will add a comment though explaining that.  Thx!

Whoah, this is a huge ^^^^^ test.  Could you break these up into smaller
tests?  One to test the simple case (a single pptr), one for harder case
(multiple hardlinks), and maybe each of the evil ones each get a separate
testcase?  Also, you might as well tag them all (in test/xfs/group) with
'pptr' or something like that, so that we can all run:

# ./check -g pptr

to run all the parent pointer tests.

This way tools/mvtest will update the tag if/when the test gets moved.

The only names that should start with an underscore are common/

These next two helpers, OTOH, might be good candidates for common/pptr
or something... as Amir points out separately, it might be faster to
implement some of this as a C helper, though a lot depends on what
exactly makes the test runtime high in the first place. :)

I also kinda wonder if xfs_io's parent command ought to have a "return
only the parent-links to this directory...

Shell commands (and bash functions) return 0 for success and nonzero for
error.

You could also just _fail directly if nothing is found.

Uppercase variable names are usually reserved for global variables, and
local function variables should be declared with the 'local' keyword to
prevent them from escaping scope. e.g.

	local parent_path="$1"

Note that setting IFS here affects everything called after
verify_no_parent, which is a side effect you might not want.

This whole thing could simply be a part of the main script body (i.e.
you don't need a helper function that's only called once)

Sure, I'll try to break them up a little and make a group to put them in.

Sure, I'll move some stuff around and see what works best.  For the 
multilink section, all but a few of the entries are links.  I do notice 
they are coming through fifo though.  I'm thinking maybe if i set up 
something that starts scanning from the bottom, worst case may turn into 
best case.

Alrighty then, will adjust the error code.  We cant fail just yet 
though, because we use this to validate that old pptrs go away when they 
should.  Like for when things move or get renamed

Not at this exact instant but I think we'll have finished the spdx
transition in kernel/xfsprogs by the time 4.18 get released.

(FWIW I have it queued up kernel-side in for-next, but as there wasn't a
tree for Monday 6/11 I haven't sent Linus a pull req yet.)

<nod> AFAICT we just return entries in the order that they land in the
attribute fork, which usually is FIFO for a clean fs.  It might not be
for an xattr tree with a lot of set/remove activity.  Userspace is
responsible for collecting all the entries and applying whatever
transformations it wants.

Understood. (Maybe a comment?) :)

I forgot to mention in my earlier reply that perhaps the IFS= should be
applied directly to the input parsing command, e.g.

cat /etc/passwd | while IFS=: read uname junk uid junk; do echo $uid $uname; done

Also, I would suggest adding a flag to the parent command to spit out
results in some sort of machine readable format.  Though given that the
only illegal character in a filename is the path separator I guess
you're stuck with:

/$ino/$gen/$offset/$name

(yes, slashes as the field separator...)

[PATCH v1 0/1] parent pointer tests

[Catherine Hoang]

Hi all,

These are the tests for Allison's parent pointer series:
https://lore.kernel.org/linux-xfs/20220611094200.129502-1-allison.henderson@oracle.com/

These tests cover basic parent pointer operations, including link, unlink,
rename, overwrite, hardlinks and error inject. This patch also adds a new
parent group and parent common functions.

Feedback is appreciated!

Thanks,
Catherine

I didn't see anywhere (in this patch) call `_require_xfs_io_command parent`.
Shouldn't we make sure the "parent" feature is support by userspace and
kernel both?

I think we'd better to check if current fs userspace and kernel support
"parent" feature. If it's supported, then we should report failure if
mkfs fails. Or we should skip the test before real testing start. (same
below)

Thanks, by the way, can you separate this patch to 3~4 patches as a patchset,
it's a little hard for me to go through this long patch and page up and down
to review sometimes :)

I remembered last time you backup the value of the xfs/debug/larp, then restore
it in cleanup, refer to xfs/018 (it might be recommended by Dave?).

I'm wondering if old kernel can mount xfs with "parent=1"? If not, we need
a _require_xfs_parent. For example we have below 3 function in common/xfs:

_require_xfs_mkfs_crc : check if current mkfs.xfs support crc=1 option
_require_xfs_crc : check if current kernel can mount a xfs with crc=1
_require_scratch_xfs_crc : check if current SCRATCH_DEV is crc enabled

As the parent feature isn't big as crc feature, so I think you can refer
to _require_xfs_sparse_inodes or _require_xfs_nrext64, check mkfs and kernel
support parent feature in one function. Then you can use:

  _require_xfs_parent # check mkfs and kernel/mount support parent feature
  _require_xfs_io_command parent # check if xfs_io support parent command

at the beginning of each cases.

unexpected output from "echo 'bad parent pointer reclen'" ?

I think it wouldnt be a bad idea to print out what the name and length
are vs what they were expected to be.  Since that will only print
during a test fail anyway, I think that's clearer than having to go
pour through the diff output.

I think it does now.  We went through a couple different
implementations of larp knobs and at some point it really wasn't
reasonable to continue pushing out all the resulting changes that would
ripple through not only usr space but all the test cases as well.  I
think thats setting down now, so I think it's ok for this line to come
out.
