Hi Nahmyung,

The series of Veronika's patches as a part of upstreaming effort of perftool-testsuite has been rebased on the latest perf-tools-next branch and should now apply cleanly. 
Patches 01/10, 02/10, and 05/10 have been dropped as they were already accepted upstream. This revision should address the problems that were previously discussed.

Thanks,
Jakub

Link to v3: https://lore.kernel.org/linux-perf-users/20250721132642.40906-1-jbrnak@redhat.com/#r

Changes since v3:
Patch 1: fix long lines, fix coding style issues, fix skipping testcases
because of missing $DIR_PATH in path to scripts used by the testscases
Patch 2: fix coding style issues, fix typo in function name
Patch 5: fix coding style issues
Patch 6: remove additional buffer and sanitize the name of log directory in
place, fix coding style issues

Veronika Molnarova (7):
  perf test perftool_testsuite: Use absolute paths
  perf tests: Create a structure for shell tests
  perf test: Provide setup for the shell test suite
  perftool-testsuite: Add empty setup for base_probe
  perf test: Introduce storing logs for shell tests
  perf test: Format log directories for shell tests
  perf test: Remove perftool drivers

From: Veronika Molnarova <vmolnaro@redhat.com>

Test cases from perftool_testsuite are affected by the current
directory where the test are run. For this reason, the test
driver has to change the directory to the base_dir for references to
work correctly.

Utilize absolute paths when sourcing and referencing other scripts so
that the current working directory doesn't impact the test cases.

From: Veronika Molnarova <vmolnaro@redhat.com>

The general structure of test suites with test cases has been implemented
for C tests for some time, while shell tests were just all put into a list
without any possible structuring.

Provide the same possibility of test suite structure for shell tests. The
suite is created for each subdirectory located in the 'perf/tests/shell'
directory that contains at least one test script. All of the deeper levels
of subdirectories will be merged with the first level of test cases.
The name of the test suite is the name of the subdirectory, where the test
cases are located. For all of the test scripts that are not in any
subdirectory, a test suite with a single test case is created as it has
been till now.

The new structure of the shell tests for 'perf test list':
    77: build id cache operations
    78: coresight
    78:1: CoreSight / ASM Pure Loop
    78:2: CoreSight / Memcpy 16k 10 Threads
    78:3: CoreSight / Thread Loop 10 Threads - Check TID
    78:4: CoreSight / Thread Loop 2 Threads - Check TID
    78:5: CoreSight / Unroll Loop Thread 10
    79: daemon operations
    80: perf diff tests

From: Veronika Molnarova <vmolnaro@redhat.com>

Some of the perftool-testsuite test cases require a setup to be done
beforehand as may be recording data, setting up cache or restoring sample
rate. The setup file also provides the possibility to set the name of
the test suite, if the name of the directory is not good enough.

Check for the existence of the "setup.sh" script for the shell test
suites and run it before the any of the test cases. If the setup fails,
skip all of the test cases of the test suite as the setup may be
required for the result to be valid.

utilized for basic test setup for the future.

From: Veronika Molnarova <vmolnaro@redhat.com>

Create temporary directories for storing log files for shell tests
that could help while debugging. The log files are necessary for
perftool testsuite test cases also. If the variable PERFTEST_KEEP_LOGS
is set keep the logs, else delete them.

From: Veronika Molnarova <vmolnaro@redhat.com>

The name of the log directory can be taken from the test suite
description, which possibly could contain whitespace characters. This
can cause further issues if the name is not quoted correctly.

Replace the whitespace characters with an underscore to prevent the
possible issues caused by the name splitting.

From: Veronika Molnarova <vmolnaro@redhat.com>

The perf now provides all of the features required for running the
perftool test cases, such as creating log directories, running
setup scripts and the tests are structured by the base_ directories.

Remove the drivers as they are no longer necessary together with
the condition of skipping the base_ directories and run the
test cases by the default perf test structure.

Although not changed here, any chance of making the naming of the file
and variables better fitting to inclusive language guidelines?

nit: I think style wise the curlies shouldn't be here:

Fwiw, there is already logic doing something like this here:
https://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next.git/tree/tools/lib/api/io_dir.h?h=perf-tools-next#n89
but iodir and not scandir so not suitably sorted. I wonder if we
should add a helper as this test seems to be common in this code?

Maybe shell_test_info with a comment saying that this is the
additional information attached to shell tests?

I think log files for tests are a good idea. We run tests in parallel
but read the stdout/stderr sequentially. For a failing test we may
fail to read stdout/stderr in some situations as the process has long
since died. Rather than add log files specifically for shell tests
perhaps update start_test to pass the file descriptors to the child
test processes and then clean up in finish_test?
