Hi,

attempt to implement Cyril's suggestions:

https://lore.kernel.org/ltp/Z69OLsDLMzNw6RGt@yuki.lan/
https://lore.kernel.org/ltp/Z69QpMlrGVDwpz8w@yuki.lan/

Kind regards,
Petr

Cyril Hrubis (1):

[LTP] [RFC PATCH 2/5] lib: Allow test to have positional args

[Petr Vorel]

Similar to $TST_POS_ARGS in shell API. This will be used in
testcases/lib/tst_run_shell.c.

I'm not really sure if this is a good approach.
But bounding the +1 value to .runs_script does not look to me good
either.

[LTP] [RFC PATCH 4/5] shell lib: Add basic support for test cleanup

[Petr Vorel]

Add basic support for test cleanup in shell loader.

This solves the problem of the order the scripts are sourced. Before it
was:

    test.sh
     . tst_loader.sh
      tst_run_shell test.sh
       . tst_loader.sh
	. tst_env.sh <- at this point in the execution you haven't even started
			parsing test.sh so you cannot run functions from there
			at all

Now new script tst_exec.sh is used to load load the test (loaded itself
by tst_run_shell):

    test.sh
     . tst_loader.sh
     tst_run_shell tst_exec.sh test.sh
      . test.sh
	. tst_env.sh

'. tst_loader.sh' (loading a script) was moved to the end, calling test
function (now forced to be tst_test) and tst_env.sh was moved to
tst_exec.sh.

There will be more improvements in the future, at least adding TST_CNT
support (will require changes in tst_test.c to handle timeouts).

Maybe variables in tst_run_shell.c could be renamed?

Re: [LTP] [RFC PATCH 2/5] lib: Allow test to have positional args

Hi,

OK this does not work for ash (busybox sh on Alpine):
https://github.com/pevik/ltp/actions/runs/13593238811/job/38004158999

*** Testing LTP test -h option ***

Kind regards,

And this is failing on old dash on Ubuntu Bionic:

I need to separate local declaration from adding value.

It seems the shell_loader_wrong_metadata.sh is a duplicate of
shell_loader_invalid_metadata. Maybe we can remove one of them.

Otherwise looks good:

Good catch. But I think there are testing a different thing:

shell_loader_wrong_metadata.sh IMHO has too high int value
("Wrong 'needs_tmpdir' type expected boolean" error):

"needs_tmpdir": 42,

# PATH="$PWD:$PWD/tests:$PATH" shell_loader_wrong_metadata.sh

                        ^
Wrong 'needs_tmpdir' type expected boolean
tst_run_shell.c:508: TBROK: Invalid metadata

shell_loader_invalid_metadata.sh IMHO has invalid JSON
("Expected ID string" error):

{"needs_tmpdir": 42,

# PATH="$PWD:$PWD/tests:$PATH" shell_loader_invalid_metadata.sh
Parse error at line 002

We do not support positional arguments for the C API. Do we really need
them for shell?

You can declare pos_args as unsigned and you don't have to add this
condition.

And this half enables the positional arguments for the C API as well. If
we set the pos_args in tst_test, then we can pass them, but there is no
way how they can be passed to the test.

So if we are going to add them, we should pass then in
extern char **tst_args or something like that.

Do we really need the tst_exec.sh?

Doesn't it work if we add what is in the tst_exec here?

The whole point of [ -z "$LTP_IPC_PATH" ]; is to detect when we are
being re-executed by the tst_run_shell, so the else branch (which
isn't really needed, because we do exit in the if) was when the test did
run.

If you change the tests to be in functions and source the tst_loader.sh
at the end it should just work.

FYI I wanted to separate this change from the actual use (next – 3rd commit).
That's why I mentioned it in the commit message.

I needed this for following change 4th commit ("shell lib: Add basic support for
test cleanup", which wrongly mentions cleanup instead of setup):

-	tst_run_shell $(basename "$0") "$@"
+	tst_run_shell tst_exec.sh $(basename "$0") "$@"

I.e. it is only for tst_run_shell.c.  I'll have look on it, if it's not needed
sure this commit would be useless. I would like to avoid this change as well.

Do you mean to avoid this change:

-	tst_run_shell $(basename "$0") "$@"
+	tst_run_shell tst_exec.sh $(basename "$0") "$@"

and put the content here? I'll try it during this week.

+1. I figured this later after doing more debugging (preparation for internal
SUSE talk).

I guess you mean to keep the original:
-	tst_run_shell $(basename "$0") "$@"

instead of what I proposed:
+	tst_run_shell tst_exec.sh $(basename "$0") "$@"

I added it to get rid of previous error:

tst_res: not found

tst_test.c:452: TBROK: Invalid child (82160) exit value 127

tst_exec.sh added in this v1 contains:

. tst_env.sh

. "$1"

if [ -n "$TST_CLEANUP" ]; then
	trap $TST_CLEANUP EXIT
fi

if [ -n "$TST_SETUP" ]; then
    $TST_SETUP
fi

tst_test
---

The most important part is:

. "$1"

which is to source the script. This cannot be added into tst_loader.sh
(it would create indefinite loop), this must be somehow added to tst_run_shell.c

And the only way I come up with was to add it via the above mentioned change of
tst_run_shell.c running actually tst_exec.sh instead of the test directly.

I guess I'm missing something.

Feel free to look into my v2, likely it's obvious to you what am I missing:
https://github.com/pevik/ltp/blob/refs/heads/shell-loader-setup-cleanup.v2/testcases/lib/tst_loader.sh

Kind regards,
Petr

So the problem seems to be that if shell parses the script before we
define aliases they are not expanded in the code shell already parsed.


This works:

alias tst_res="..."

tst_res TINFO "foo"


This does not:

tst_res TINFO "foo"

alias tst_res="..."

The tst_loader.sh has to be sourced first after all.

Hi!
And one possible solution is to source the environment first and the
loader last, on the top of your shell-loader-setup-cleanup.v2 branch:

OK, that is the missing piece, thank you!

i.e. sourcing tst_env.sh at the beginning before test function setup and
tst_loader.sh at the end after test function setup). I thought we would avoid
sourcing two files in the tests, that's why I haven't tried, but that's a minor
detail. And it's better solution than having tst_exec.sh, which requires
tst_run_shell.c modification, just to do the same thing (source tst_env.sh).

Kind regards,
Petr

Given all the choices I too think that soucing tst_env.sh first to get
all the defitions and tst_loader.sh to start the test is the cleanest
solution.
