[LTP] [PATCH 0/8] shell: $TST_ALL_FILESYSTEMS (.all_filesystems)

[LTP] [PATCH 0/8] shell: $TST_ALL_FILESYSTEMS (.all_filesystems)

[Petr Vorel]

Hi,

.all_filesystems implementation for shell.
Motivation is to add .all_filesystems for shell NFS tests.
Now added to nfs07.sh (fast test).

It required to export tst_clear_device() for shell via tst_clear_device.c.
TODO: doc
NOTE: df01.sh and mkfs01.sh should probably be converted to use it.

Kind regards,
Petr

Hi!

Isn't the TST_MOUNT_DEVICE redundant here? We set the mount flag only if
the device was mounted by the library. Or do I miss something?

Other than that it looks fine.

No, you're right $TST_MOUNT_DEVICE is redundant. I noted this after sending a
patch, just forget to note it on ML. Thanks!

[LTP] [PATCH 3/8] tst_test.sh: Improve pattern for allowed variables

[Petr Vorel]

to allow using '... $TST_FOO'

i.e. without filtering '
EXPECT_PASS "grep '$TST_MNTPOINT $TST_FS_TYPE' /proc/mounts"
would produce warning:
tst_mount_device 1 TWARN: Reserved variable TST_FS_TYPE' used!
because sed filters it as: FS_TYPE'

Will be needed for next commit.

Well, '"'"' was my version of adding ' (quoted with " and ' at the start and end
were for ending previous '.

But this is shorter: '\'', therefore suggest

I would say that '\'' is stil insane, but I guess that we can't do
better than that.

IMHO better than using variable:
local _tst_q="'"
for _tst_i in $(grep '^[^#]*\bTST_' "$TST_TEST_PATH" | sed 's/.*TST_//; s/[='$_tst_q'"} \t\/:`].*//'); do

insane: well, POSIX shell is insane :).

Re: [LTP] [PATCH 5/8] shell: Add tst_clear_device

[Petr Vorel]

Hi Cyril,

> Hi!

Not sure what you mean, can you be more specific?

I wasn't clear in git commit message that shell API also needs call
tst_clear_device(), but we use mkfs.* binary directly, instead of tst_mkfs_()
via SAFE_MKFS(), but this is obvious to you.

Alternatively we could create binary testcases/lib/tst_mkfs.c which would 
run SAFE_MKFS(). We already have all code in C and both C and shell API would be
even more consistent.

Kind regards,
Petr

We do have tst_device binary that has two commands acquire and release,
why can't we add clear command for that binary instead?

Ah, you mean testcases/lib/tst_device.c. I forget on this one, I was looking
just into lib/tst_device.c. Makes sense, thx!

I guess this whole workaround is not needed for binary being used only in new
shell API (note for myself in case we decided to introduce new binary wrapper).

I do not get the TST_MOUNT_FLAG, what do we need it for? The tst_run()
should be called exactly once in the test and at this point the
TST_MOUNT_FLAG cannot be set.

Correct, $TST_MOUNT_FLAG should be removed here.

Probably going to the directory is better testing:

EXPECT_PASS "cd $TST_MNTPOINT"

(I originally counted as successful testing even running TST_ALL_FILESYSTEMS=1
is kind of a smoke test.)

Kind regards,

It will not be that simple. Because $TST_TMPDIR is not the mountpoint
($TST_MNTPOINT mountpoint is $PWD/mntpoint, which is $TST_TMPDIR/mntpoint for
$TST_ALL_FILESYSTEMS) IMHO we need at least to:

1) cd to $TST_MNTPOINT on lhost and rhost (nfs_setup_server() runs NFS server
on lhost for netns, otherwise on rhost)
2) local_dir and remote_dir in nfs_setup need to use $TST_MNTPOINT instead of $TST_TMPDIR
=> it'd be easier to port *all* NFS tests to $TST_ALL_FILESYSTEMS, not sure if we
want that.

Kind regards,
Petr
