Request for --logging-level=INFO to limit logging capture

[jpellerin]

What steps will reproduce the problem?

1. create an app like a pylons app or something that logs a lot of messages
2. run nosetests

What is the expected output? What do you see instead?

As expected, logging messages at all levels are captured including DEBUG.
But it would be nice if one could limit the level like this:

nosetests --logging-level=INFO

Then only messages at that level or above would be captured. What should
happen to the messages beneath that level? They should probably be
swallowed I think. The problem to solve is that the nose captured output
can grow enormously with the DEBUG level and can become hard to read.

What version of the product are you using? On what operating system?

0.11

I have the same problem using nosetests fenics; debug level logging prints and enormous amount of internal data structures etc. For now just using --nologcapture, but would be nice to be able to change the level rather than just disabling.

I mean nosetests with fenics based code :)

Awesome, thanks for starting a patch! It looks like it just needs a translation between readable logging levels and numeric levels. As is, I don't see how it would work because the value of logging.NOTSET is actually 0 not 'NOTSET'.

No worries. I think getattr(logging, self.loglevel) does what we want here. Right?

http://code.google.com/p/python-nose/issues/detail?id=268 has an incomplete patch (tests needed)

Should this issue be closed now it is available as part of the logcapture plugin?

I verified this feature on nose 1.3.7. But you should specify -s option before --logging-level=INFO.
