[LTP] [PATCH 0/5] shell: Add TST_FORMAT_DEVICE support

[Petr Vorel]

Hi,

it's nice to sync with C API, but I don't expect that many tests would
need formatting device.  The main reason is to preparation for
TST_ALL_FILESYSTEMS support (useful for NFS tests).

Kind regards,
Petr

[LTP] [PATCH 1/5] tst_test.sh: Add $TST_DEFAULT_FS_TYPE

[Petr Vorel]

To sync with C API which also has defined the default filesystem.

That required to whitelist ) added after variable to allow use in help:
(currently $TST_DEFAULT_FS_TYPE).

Use it in df01.sh, mkfs01.sh (the only tests which works with
filesystems).

Actually if we wanted to sync with the C library it should be:

if [ -z "$TST_FS_TYPE" ]; then
	if [ -n "$LTP_DEV_FS_TYPE" ]; then
		export TST_FS_TYPE="$LTP_DEV_FS_TYPE"
	else
		export TST_FS_TYPE="ext2"
	fi
fi

That's equivalent of the .dev_fs_type in the tst_test structure as we
do:

	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.

Ah, I forget on $LTP_DEV_FS_TYPE, thanks.

nit: or shorter
if [ -z "$TST_FS_TYPE" ]; then
	export TST_FS_TYPE="${LTP_DEV_FS_TYPE:-ext2}"
fi

BTW I meant TST_DEFAULT_FS_TYPE="ext2" as equivalent of
#define DEFAULT_FS_TYPE "ext2"
from include/tst_defaults.h.

Because df01.sh help uses hardcoded ext2:

[LTP] [PATCH 2/5] tst_test.sh: tst_mkfs(): Add support for extra opts

[Petr Vorel]

Allow to pass options after device name
(to sync with C API).

NOTE: not adding it to legacy shell API (thus no need to change

Doesn't this actually break the examples described in the
doc/shell-test-api.txt?

There we do have:

tst_mkfs ext4 /dev/device -T largefile

Which obviously parses as "-T" in the fs_opts and "largefile" in the
extra_opts.

I do not think that the support for extra opts can be added this way
without redesigning the tst_mkfs API. Maybe it would make more sense to
just pass the parameters in the same way we end up passing them on a
command line, i.e. we would only interpret the first parameter passed to
tst_mkfs as a filesystem type and pass the rest as $@.

Good catch, I forget to check examples in docs.

-T largefile would have to be quoted:
tst_mkfs ext4 /dev/device "-T largefile"

But then you'd have to always pass a device ($TST_DEVICE).
And the problem is that I wanted to specify the options before loading
tst_test.sh (together with TST_FORMAT_DEVICE=1). At this point TST_DEVICE
is empty string. Therefore I'd prefer to quote fs-options to be passed to
tst_mkfs as single option.

OTOH mostly only fs-size is the parameter, not really used now.

Kind regards,
Petr

OK, now I understand you. It's all about tst_mkfs having $1, shift and rest $@.
And we avoid quoting as you suggested :).

But TST_* variables in stay the same. => I'll implement it in v2.

Thanks!

Cyril, we forget on think: when passing everything as $@, we just don't know
what is the device.

Thus I'll change
tst_res TINFO "Formatting $device with $fs_type opts='$fs_opts' extra opts='$extra_opts'"
with
tst_res TINFO "Formatting $fs_type with opts='$opts'"

It's just a minor logging problem.
We also loose check for missing device, that's not ideal as it's mandatory, thus
I'll add some check when using the default $TST_DEVICE.

Petr

[LTP] [PATCH 3/5] tst_test.sh: Add $TST_FORMAT_DEVICE and related vars

[Petr Vorel]

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

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

This would work with the proposed change to tst_mkfs if we swapped the
$TST_DEV_FS_OPTS with $TST_DEVICE.

Do you mean to swap here? i.e.:
tst_mkfs "$TST_FS_TYPE" "$TST_DEV_FS_OPTS" "$TST_DEVICE" "$TST_DEV_EXTRA_OPTS"

But in tst_mkfs it has always been the second parameter:
local device=${2:-$TST_DEVICE}

What am I missing?

Kind regards,
Petr

The email that explains why we can't add dev_extra_ops to the tst_mkfs
the same way we do in C?

[LTP] [PATCH 5/5] shell: Add test for TST_FORMAT_DEVICE=1

[Petr Vorel]

Unfortunately GitHub Actions don't have loop devices, thus cannot be run
in CI:

tst_format_device 1 TINFO: timeout per run is 0h 5m 0s
/__w/ltp/ltp/lib/tst_device.c:139: TINFO: No free devices found
