[LLVMdev] LIT Verbose

[Daniel Sanders]

If I remember correctly, there was some talk in ninja's github issues about not buffering when there's only one command to run. Is it possible that your manual runs are using a newer version of ninja?

Also, I remember there being some talk about printing 'still waiting...' messages when a command hasn't finished for a while. That would stop the timeouts but it would also remove the protection against infinite loops.

Folks,

Some of our CMake buildbots are failing to timeout, and I believe it's
something to do with how the output comes from the LIT tests, even
though we add -v to LIT_ARGS.

When the "check-all" stage runs, the output stops at the "Running
tests" message and only prints the rest of the output (including all
tests that pass, fail, etc) at the end.

I believe this has to do with ninja holding off the stream until the
job actually finishes, but I'm not seeing this when I run ninja
manually, which hints as to how the terminal is setup for buildbot.

Does anyone have a good hint for me to fix this?

cheers,
