Pull request overview
This PR modernizes Rally’s subprocess helpers in esrally/utils/process.py by migrating legacy subprocess.call() / Popen() usage to subprocess.run() and replacing preexec_fn-based detaching with start_new_session.
Changes:
- Switch
run_subprocess()andrun_subprocess_with_output()tosubprocess.run(). - Replace
preexec_fn=os.setpgrpwithstart_new_session=detachfor detaching. - Simplify output capture by relying on
text=Trueand processingCompletedProcess.stdout.

The next question is: why do we have four different ways to run subprocesses? Do we even need those helpers now that subprocess.run() exists?
