Now that we have 1.1.0 out, I was thinking maybe now is the time to merge the matplotlib-py3 branch into master. As a reminder, the main downside is losing compatibility with Python 2.5 and earlier. We would continue to have a 1.1.x maintenance branch for the foreseeable future for small-yet-critical bugfixes, and can still make a Python 2.5-compatible bugfix release from that. Any objections or concerns? Any reason to hold off? Mike |

I haven't begun to look into that and have only been using 2.6 and 2.7 for a while now. Ben Root |

Any reason to hold off? Mike, I agree, we have to do this, and now is the time, before the work you have already done gets too stale and hard to merge in. My main worry is how to support the resulting py2.6-py3.2 master: 1) In the coding guide, it might be good to have notes (tips) about how to maintain compatibility, or at least references to such notes. I have read about py3 but have never worked with it. 2) This is going to make development significantly harder--having to think about the compatibility requirements, and having to test everything with 2.x and 3.x. 3) Most of the interactive backends will be unavailable, correct? 4) I hope the 1.1.x branch doesn't have to be maintained too long; or if it does, it would be good to have a single designated maintainer to take care of it, backporting from master or applying custom fixes as needed.

Right now, I build/install/test three branches on a regular basis. After the merge, we go down to two. Mike |

WxPython seems like it's still a long way from supporting Python 3 (though I'm not terribly plugged into that community). Note, however, the wx backend will continue to work for users running Python 2.x, just as it always has. There is no need to chop this off completely.

Sorry for the double post. Having trouble with my mail transport today. The one with the later date is the "canonical reference". :) |

Hey guys, On Fri, Oct 28, 2011 at 11:41 AM, Eric Firing <ef...@ha...> wrote: > 1) In the coding guide, it might be good to have notes (tips) about how > to maintain compatibility, or at least references to such notes. I have > read about py3 but have never worked with it. +1 for the py3 merge! IPython master is already fully on py3 and we should be releasing very soon 0.12 with this. So once mpl is merged, it will be possible to have from either releases or master, the full 'minimal stack' (numpy/scipy/mpl/sympy/cython/ipython) on py3, which I think is awesome. In case it's of any use to you guys, feel free to pillage our little bag of utilities for py3 compatibility: https://github.com/ipython/ipython/blob/master/IPython/utils/py3compat.py By grepping the IPython sources for py3compat imports you can also see how we use them, in case it helps. Best, f ps - full credit on all this in IPython goes to @takluyver, who joined the project initially just based on his need to have ipython on py3 and has turned out to be an all-around amazing member of the project. I'm sure if you guys hit any bumps he'd be able to help out, as he uses py3 regularly as his default platform and therefore knows quite a bit about it. |

The pull request to merge the py3 fork back into matplotlib/master is here: https://github.com/matplotlib/matplotlib/pull/565 Thanks to everyone who worked on it. I plan to leave this up for a while and get as much chance for review as possible.

BTW -- the diff is so large that viewing this page crashes my browser
tab (in Chrome). YMMV. You can view the diff locally by first getting
my repository:
git remote add mdboom git://github.com/mdboom/matplotlib.git
git fetch mdboom
then diffing with an external tool:
git diff --ext-diff upstream/master mdboom/py3-merge
Of course, we can't use github's code review features that way :(
