[PATCH 0/3] recipetool/devtool: send errors to stderr

[Christopher Larson]

From: Christopher Larson <chris_larson@mentor.com>

This aligns with the behavior of bitbake proper. There is a bit of code
duplication between knotty and scriptutils, but that's not new -- that was the
case before as well. We should consider moving these logger configuration
functions into bb.msg.

The following changes since commit 2ad7308ee7166641eff99f3b9fe6794de143f6bc:

  oeqa/utils/qemurunner.py: Remove duplicate message on LoggingThread start (2015-09-22 18:13:02 +0100)

[PATCH 1/3] oe.scriptutils: enable color in a more flexible way

[Christopher Larson]

From: Christopher Larson <chris_larson@mentor.com>

Rather than recreating handlers and forcing them, iterate over the handlers
and enable color on ones we can handle. This makes it easier to handle color
properly when we introduce the bb.msg default log filters.

[PATCH 2/3] oe.scriptutils: add logger_setup_filters

[Christopher Larson]

From: Christopher Larson <chris_larson@mentor.com>

This function sets up the default bb.msg formatter and log filters, which by
default sends ERROR messages to stderr rather than stdout.

Hmm, might be worth making this even more generic and moving it to bb.msg.
If one was to run this against a logger which isn't configured to use
BBLogFormatter, this would do nothing. It should probably raise an
exception if that occurs, or automatically replace the stock formatter
instance with a BBLogFormatter instance using the same format string.

Does anyone happen to know if there any objection to this? I just noticed
this hasn't been merged yet. This makes the behavior of recipetool and
devtool more consistent with bitbake itself by sending errors to stderr.
Long term I'd like to see warnings go there as well, but that could be more
controversial and is a later task, I think this should go in as is.
Eventually we should consolidate some of the logger setup and configuration
logic between scriptutils and bitbake as well, but that was the case with
or without this series

I certainly don't - I did see this hadn't been merged a few weeks back, I 
should have acked it.

There's also a similar scriptutils-log-improvements-2 branch, what branch
is the one you want merged?

The scriptutils-log-improvements branch, please. scriptutils-log-improvements-2
includes bits which aren't yet ready. Thanks.
