v2:
- added 'return_code' to the common section of the JSON output
- dropped 'inversion' as we have 'return_code' in pip_stress
- dropped 'success' as we have 'return code in ssdd
The first two patches fixes the format string issue. Then there are a
couple of patches which fixes the common JSON entries (command line,
start_time, end_time).
Then there are patches which add the --output parameter to the missing
rt-tests programs.
All patches are also available at:
https://github.com/igaw/rt-tests/tree/json-output-2021-03-05
Daniel Wagner (14):
cyclictest: Fix printf format specifier
cyclicdeadline.c: Fix printf format specifier
signaltest: Add missing --output usage info
rt-util: Copy command line before getopt_long() is called
rt-util: Add start time of test execution for JSON output
rt-util: Add return_code to common section of JSON output
pip_stress: Move test result output to main
pip_stress: Return failure code if test fails
pip_stress: Prepare arg parser to accept only long options
pip_stress: Add JSON output feature
pi_stress: Prepare command line parser for long options only
pi_stress: Add JSON output feature
ssdd: Add quiet command line option
ssdd: Add JSON output feature

The fields are not uint64 just longs, update the printf format
specifiers.

By default, getopt_long() permutes the contents of argv as it scans,
so that eventually all the nonoptions are at the end. This is
confusing in the JSON output, thus copy the command line before we
call getopt_long().
Introduce a rt_init() which copies the command line. This makes also
rt_write_json() function arguments a bit cleaner.

output.

Instead printing the result high() close directly move it to main()
function to simplify the return code if the test fails.

The quiet option is useful for automated test setups where
only the final result of the run is interesting.

I am pretty happy with the this version now. That means I don't plan to
change more on the JSON feature. Well, one thing I am still not really
happy is the name '--output'. But as no one had any better idea, let's
keep it as it is. Hopefully no one wants it changed in 2 weeks from now
:)
So if you want to do a release, please go ahead.
Thanks,
Daniel

How about --json ?

Ah, that reminds me why I opted for output initially. We had the
discussion to support different output formats. But if we just stick
with JSON, --json is way better.
What about finishing this series first and then I send the output ->
json cleanup?

whoa, so we're going to use 4096 even if we're not using formatted output?
I suppose most people won't care, but embedded folks might. We can do
better. Why not loop through once and calculate the size, and then malloc
the memory, and only if the person choses the formatted output option.

So just because you didn't want to test i < argc -1
you put the i++ here instead of in the for loop where we would expect it?
Looks ugly, and is unnecessary.

Why are you doing this again, you already did this, you could have stored
it then. offset is misleading to, the whole thing could look like this
for (i = 0; i < argc; i++) {
size += strlen(argv[i]) + 1;
strcat(cmdline, argv[i]);
if (i < argc - 1)
strcat(cmdline, " ");
}
Not including looping through it once to determine the size to malloc
that should only happen if the user is using formatted output.

Yes unfortunately. We only know after we used getopt_long() that we should
have stored argv, kind of chicken-egg situation.

One more thing, could you please break your patches up into smaller more
manageable sizes?
I would put for example changes to rt-utils in one patch
It might be a pain to then create a separate patch for each test to
interact with it, but imagine that we get the situation where the changes
don't work well with a particular test, I'd rather just revert the one
test that revert everything.
Thanks
John
