[CHOP]
OK, I've checked in changes to suppress all the warnings in the test
suite. I tried to be as targeted as possible so that any regressions
from the current state in terms of warnings should show up.
I suspect that there may be some issues with regards to masked arrays
issuing spurious warnings. I'm not a ma user, so I didn't take the time
to investigate this, but someone who cares should probably look at this
and consider how to resolve it.
Also with regard to the recent addition of the errcall argument to
errstate, it appears that if errcall is *not* specified, self.errcall
will be set to None. This means that any existing error callback will be
removed when entering the block (and replaced when you leave). I don't
think that's the desired behavior. Instead, if errcall is not specified,
I believe we should leave the value of errcall alone. Does that sound
right, or am I missing something? This would result in something like:
def __init__(self, **kwargs):
if 'errcall' in kwargs:
self.errcall = kwargs.pop('errcall')
else:
self.errcall = geterrcall()
self.kwargs = kwargs
This still allows you to set the errcall to None for the block by using:
with errstate(errcall=None):
# do stuff
Hmm. Should that be 'errcall' or just 'call'? 'errstate(errcall...)'
seems somewhat redundant.
Finally, and this is a moot point anyway assuming the above rewrite, is
there a reason to use:
if 'errcall' in kwargs:
self.errcall = kwargs.pop('errcall')
else:
self.errcall = geterrcall()
rather than simply:
self.errcall = kwargs.pop('errcall', None)
?
