Re: [PATCH v2] common/filter.btrfs: introduce _filter_snapshot

Qu Wenruo <quwenruo.btrfs@xxxxxxx> · Mon, 8 Apr 2024 17:54:51 +0930

在 2024/4/8 14:02, Anand Jain 写道:
Btrfs-progs commit 5f87b467a9e7 ("subvolume: output the prompt line only
when the ioctl succeeded") changed the output for snapshot command,
updating the golden outputs.

Create a helper filter to ensure the test cases pass on older btrfs-progs.

Another option is to remove the 'btrfs subvolume snapshot' command output
from the golden output and redirect it to /dev/null, but this strays from
the bug-fix objective.

v2: The missed testcases included now.
     Merged following two patches in v1:
	common/filter.btrfs: add a new _filter_snapshot
	btrfs: create snapshot fix golden output

Still I do not think this is correct way to go.

3 points for my objection:

- Most test cases are already doing the redirection for "btrfs
  subvolume" command group
  Check my patch's commit message, overall the touched ones are less
  than 25% of all the "btrfs subvolume snapshot" calls.

- Missing handling for "btrfs subvolume delete"
  Sure you can add new filters, but I do not think it's worthy just a
  new filter.

- How to enforce the filters for the future test cases?
  Good luck if you're really pushing everyone to use the new filter.
  On the other hand, it's pretty instintive to just redirect the output.
