Running thin behind a pipe doesn't show messages #371

Open rp-pedraza opened 4 years ago

rp-pedraza commented 4 years ago

I'm trying to merge thin's output with another static auto-builder command using parallel --line-buffer ::: 'thin ...' 'another command' and I'm not seeing thin's messages. Is it perhaps buffered?

thin ... | cat doesn't show anything either but I can verify that server is running well with the browser.

Tested this with 1.7.2 and a65c608e014f640a8a63c5c2dd00666fd8eff683.

Is it printing to stdout or stderr?

Is it printing to stdout or stderr?

It prints messages normally while not being piped. But if I append | cat there's nothing. However if I force to run it in an invalid directory it does produce stderr errors. I can't tell if the error messages are just shown after the buffer is flushed in exit.

It sounds like logging is going to stderr. Well, if you want to submit a PR to fix this, it would be welcome.
