Debug mode much needed as a developer to debug

[omkarns]

There are test cases which gets failed in parallel, it gets difiicult to debug if output is suppresed on the console. We need that functionality to use it. I agree it adds bvalue as it enabled me to run tests in parallel. But giving output on screen will more or less help in debugging even if it is printing on screen at different timings due to speed of execution. It will be a pie on the cake.

Not sure if I follow, do you need the output in realtime? If you don't mind doing something locally you might be able to replace this line:

gtest-parallel/gtest_parallel.py

Line 219 in aabba21

task = subprocess.Popen(self.test_command, stdout=log, stderr=log)

I don't know if there's something non-hacky and minimal for this. If I recall correctly this used to use a pipe, but that led to various flakiness when using it in the wild, using whatever python version we were using at the time.

.. which if I read the python docs right are replacing stdout=log with =subprocess.STDOUT. I haven't thought further about what this implies.
