Thanks and congratulations to everyone involved as well; I've built 1.2.1 on
MacOS X with fink for
Python2.6-3.2 without any failures in the test suite!
I did run into a problem though that has actually existed since the first 1.2
release - with the MacOSX
backend line plots of somewhat larger arrays with significant "high-frequency"
power had extremely
degraded, e.g. something like
x = np.linspace(0,10,1.e6)
y = np.cos(x)+0.2*np.sin(x*3.e3)+0.1*np.cos(x*4.e4)*np.random.rand(1.e6)
plt.plot(x, y)
would display within less than 2 seconds with 1.1.1, but with 1.2.x you
literally have to wait minutes,
and it takes similarly long to zoom in as long as you have a substantial part
of the line in the window.
I found in the current HEAD (9e477b3) this has finally been fixed - thanks for
that as well, whatever
the problem was, but now in the 1.3 branch the _macosx backend has been
altogether disabled!
I verified after removing that RuntimeError from _macosx.m that the backend
still works and is indeed
up to its old speed; but if that change stays in, it won't be usable from
non-framework Python installs
like the fink ones.
Personally, I am aware of the problems with the missing window manager control,
and occasionally
am annoyed by hunting for a plot window that has sneaked somewhere underneath
other windows,
but with that in mind I still prefer the MacOSX backend to any of the others,
and I would suggest to
leave it at a warning rather than an error, so users can still decide for
themselves if they want to put
up with the possible troubles.
Cheers,
Derek
