Recently we found out xfs_repair were not repairing
root inode parent pointer when root inode is on short-form
and parent points to an invalid inode number (refer to:
"xfs_repair: Fix root inode's parent when it's bogus for sf
directory" on xfs-devel list).

This test checks if xfs_repair successfully repair the
filesystem in the scenario mentioned before.

Isn't this last "filesystem is not corrupt" check run by the harness
via _check_scratch_fs()?

(Also, "if [ .. ]; then" is the preferred fstests style)

There's no test output, so the normal thing to do is this after
setting up the test:

echo "Silence is golden"

We do that early on so that when something goes wrong the bad output
file immediately tells you that no output was expected.

also  the metadata and repair groups should be added here.

Apart from Dave's comments, there're some common definitions missing
too, e.g. 'tmp' and 'here', please use './new xfs' to generate new test
template.

BTW, I've applied the first patch, no need to resend it in v2.

Thanks,
Eryu

Eryu, I think I suggested that Marco could remove the "tmp" definition
because it's not used in the script.  Is there some reason to keep it?
The script did start out with a "./new xfs" generation template.

Oh, I bet some helpers depend on it... sorry, my mistake.  Oops.

(though maybe tmp should just get hoisted to the harness and
not be required in every script, but I digress ...)

Thanks,
-Eric

You mean like I proposed a couple of weeks ago along with the
spdx license tag updates?

https://www.spinics.net/lists/fstests/msg09849.html

that's next on my list of "Big cleanups for fstests To Do" list.

Cheers,

Dave.

Hi Eryuy et al,

firstly thanks for the reviews.

OK, I'll resend just the test itself (without the one which hoist the
helper function for sfdir format).


Given Eric's and Dave's updates, should I re-include the common
definitions even those being unused within
this test scope?

If those are used by helpers or any other flow on xfstest I do agree
with Eric and Dave about hoist it.

Thanks,

Hello all,

just FYI just sent out v2 covering Dave's and Eryu's suggestions.

Thanks,
