Subject: [PATCH v6] xfstests: add test for btrfs cloning with file holes
Date: Tue, 10 Jun 2014 11:12:48 +0100	[thread overview]
Message-ID: <1402395168-17568-1-git-send-email-fdmanana@gmail.com> (raw)
In-Reply-To: <1401499053-11162-1-git-send-email-fdmanana@gmail.com>

Regression test for the btrfs ioctl clone operation when the source range
contains hole(s) and the FS has the NO_HOLES feature enabled (file holes
don't need file extent items in the btree to represent them).

This issue is fixed by the following linux kernel btrfs patch:

    Btrfs: fix clone to deal with holes when NO_HOLES feature is enabled

Signed-off-by: Filipe David Borba Manana <fdmanana@gmail.com>
---

V2: Increased test coverage by testing the cases where a hole overlaps
    the start and end of the cloning range.

V3: Test the case where the cloning range includes an hole at the end
    of the source file and might increase the size of the target file.

V4: Added test for the case where the clone range covers only a hole at
    the beginning of the source file.
    Made the test be skipped if the available version of mkfs.btrfs
    doesn't support the no-holes feature. And when testing the case
    where the no-holes feature isn't enabled, explicitly ask mkfs.btrfs
    to disable no-holes (future versions of mkfs.btrfs might enable
    this feature by default).

V5: Detect if kernel supports NO_HOLES feature too. Added some messages
    (echoes) before each od call to make it easier to match output
    with each specific test.

V6: Pass -s to xfs_io when creating the test files.
