stdout/stderr

Hi, it seems that docker-squash is using the stderr stream to provide info messages.
However this breaks automated build systems, which rely on stderr to detect actual errors.
Is this intended behaviour?
Thanks for checking.

Name: docker-squash
Version: 1.0.5 (from pip)

That is a surprising info. How do you execute it? Can you give me some output that is redirected to stderr?

[brubbel]

docker-squash hello-world -t hello-world-squashed 2>/dev/null
In my version, docker-squash will run silent until finished.

I can confirm this. I'll take a look, thanks!

It looks that the StreamHandler by default writes to stderr: https://docs.python.org/2/library/logging.handlers.html#logging.StreamHandler This is an easy fix.

If possible, can you also publish this fix to PyPI later on? Thanks for the fast solution!

Yes, definitely. This will be part of 1.0.6 release. I do plan to add a few other issues to this release.
