[LTP] [PATCH v2 0/6] Add TST_FORMAT_DEVICE support

[LTP] [PATCH v2 0/6] Add TST_FORMAT_DEVICE support

[Petr Vorel]

Hi,

changes v1->v2:
* Replace $TST_DEFAULT_FS_TYPE with proper $TST_FS_TYPE initialization
  (Cyril)
* Redesing tst_mkfs() API (Cyril)
  We now parse only fs_type, the rest we pass to mkfs.* the same way we
  end up passing them on a command line.

Petr Vorel (6):
  tst_test.sh: Properly init $TST_FS_TYPE
  tst_test.sh: Redesing tst_mkfs() API
  tst_test.sh: Add $TST_FORMAT_DEVICE and related vars
  df01.sh: Use TST_FORMAT_DEVICE=1
  shell: Add test for TST_FORMAT_DEVICE=1
  doc: Add missing shell variables

[LTP] [PATCH v2 1/6] tst_test.sh: Properly init $TST_FS_TYPE

[Petr Vorel]

to sync with C API init $TST_FS_TYPE with $LTP_DEV_FS_TYPE, when
defined. That's equivalent of the .dev_fs_type in the tst_test
structure:

    if (tst_test->dev_fs_type)
	    tdev.fs_type = tst_test->dev_fs_type;
    else
	    tdev.fs_type = tst_dev_fs_type();

    (And the tst_dev_fs_type() returns either $LTP_DEV_FS_TYPE or "ext2"
    if it's not defined.)

Now, when $TST_FS_TYPE properly defined, tst_mkfs() can rely on it
(thus define the check).

Also use the variable in df01.sh, mkfs01.sh (the only shell tests which
works with filesystems).

[LTP] [PATCH v2 2/6] tst_test.sh: Redesing tst_mkfs() API

[Petr Vorel]

the goal is to add support for extra opts after device name
(e.g. size) - to sync with C API.

But instead adding new variable for extra opts we specify only
$fs_type and the rest of args we just pass to the mkfs.* command.
Still keep $TST_FS_TYPE and $TST_DEVICE as a default when no parameters
are passed.

NOTE: not adding it to legacy shell API (thus no need to change
test_robind.sh).

i.e.: TST_DEV_EXTRA_OPTS, TST_DEV_FS_OPTS, TST_FS_TYPE
(to sync with C API).

NOTE: stop using pattern 'TST_NEEDS_FOO', sometimes 'NEEDS' just does
not fit to variable name.

A small nit, I prefer to use test name directly if we don't have several

Sure. Originally I had more tests there, using lsblk.
But I'll probably extend these tests to your suggestion in different mail.

And remove the parentheses here as:

'$TST_DEV_EXTRA_OPTS' extra 'mkfs'' options _after_ the device path.

AFAIK it does not in AsciiDoc format (not sure about other, but we don't want to
switch anyway). I guess I can keep it as we don't have any better solution,
right?

We have checked df command in TST_NEEDS_CMDS, why still check it again
in here?

This is left over from previous versions => should be deleted.

Correct, TST_NEEDS_CMDS should be removed so that at least creating the device
(test1) is supported even SUT is missing df.

And what do we need the lsblk command for?

Other than the TST_NEEDS_CMD= variable:

Re: [LTP] [PATCH v2 6/6] doc: Add missing shell variables

[xuyang2018.jy]

Hi Petr

This patchset looks good to me, so
Acked-by: Yang Xu <xuyang2018.jy@fujitsu.com>

ps: I think we can add two basic tests for this,
1)test TST_FS_TYPE whether format the specified filesystem ie using ext4
2)test tst_mkfs whether format failed if not specifying TST_NEEDS_DEVICE
and call tst_mkfs directly

Best Regards

BTW the default is ext2. Also not sure how to do it when formatting loop device.
Verifying filesystem I'll add when I add TST_NEEDS_MOUNT flag.

losetup prints:
/dev/loop0: [65025]:176189 (/tmp/LTP_tst_format_device.9bya3blyQD/test_dev.img)

> 2)test tst_mkfs whether format failed if not specifying TST_NEEDS_DEVICE

+1. I'll also document here what is the purpose (we have many tests which are
expected to TFAIL/TBROK, but it's not documented in the tests thus it's hard to
run them locally.

Kind regards,
Petr
