Release Candidate

Development matplotlib-devel
1

Today is the scheduled day for release candidate 1.2rc1.

We seem to be in really good shape. Thanks to everyone that has been working so hard to squash bugs, particularly ones that turned out to be bottomless rabbit holes.

We have a few outstanding issues, which I'll categorize below:

Critical things that need just a little more work:

#1223 dpi= for bitmaps not handled correctly
#1209 Pass linewidth to Mac context properly
#786 savefig() renders paths and text differently than show()
#113 dpi= doesn't seem to have any effect with MacOS X backend

#1208 FAIL: matplotlib.tests.test_text.test_contains.test release_critical
#1176 Reverted a previous change to artist transform setting. Fixes legend bug.

Non-critical features that are near completion -- just needing some confirmation or testing:

#847 Add stacked kwarg to hist and implement stacked hists for step histtype
#751 Building on osx with python 3.2 OSX

Problems requiring a fix in another project:

#1126 Qt4 save dialog not functional on CentOS-5

Things that are probably too big to fix now, but deserve warnings in the release notes:

#854 Bug in Axes.relim when the first line is y_isdata=False and possible fix
#740 plt.pcolormesh and shape mismatch
#162 twinx and plot_date confirmed

Reminders for the release manager:

#1207 Add contributor and git stats to documentation
#1070 Use github for downloads

I will write prose for the "too big to fix now" stuff, and I trust the other close things will get done by their respective authors. Then we're very close to getting a release candidate out.

Congratulations to everyone for a job well done!

Hello,

Do you still accept pep8 cleaning up ? I’ve got a couple of important deadlines coming up soon, but I might be able to clean up the whole code.

Thanks,

I'd certainly like to see that work continue, but I don't know if it's worth holding up the release candidate for. We probably won't get it out today given the other critical things yet to go in -- but once the release candidate is cut, I'd prefer to be really conservative about what changes go in before the final release. We can continue your great PEP8 work on master (after the 1.2.x maintenance branch is created), of course.

My offer to test on Windows still holds. The question is test what? Assuming that the intent is to support Python 2.6/7 and 3.1/2/3 then different versions of Visual Studio are needed as detailed here Issue 13210: Support Visual Studio 2010 - Python tracker. I can't see much sense in me trying to build and test all that lot while other volunteers are doing exactly the same thing at the same time. Is there a cunning plan somewhere to cover this that I've missed?

The process is usually that the release is tagged in github, a tarball is created, and then various platform specialists create the binary releases. For the last release Christoph Gohlke did the Windows builds, and I assume he is able to do that again this time. Perhaps it makes sense to coordinate with him to share some of that work? Anything we can do to lessen the burden on any one person is always appreciated.

Even leading up to the tagging of the release candidate, it's always helpful to build from github periodically and test on the platform and version of Python that's most important to you, and report back into the issue tracker any test failures or other glitches.

#1223 dpi= for bitmaps not handled correctly

I don't believe this is release critical. It only affects metadata.
Eric has fixed this for TIFFs but there may be outstanding issues with
other bitmap types. My feeling is that the below issues should receive
more attention.

#1209 Pass linewidth to Mac context properly
#786 savefig() renders paths and text differently than show()
#113 dpi= doesn't seem to have any effect with MacOS X backend

Michiel has provided great feedback regarding the previously proposed
solution to part of this problem, and this has been reflected in the
updated pull request.

Hello,

sure, I can provide the Windows binaries and run tests. I have not tried recent master, but I am using a ~2 month old build on Python 3.2 and 3.3 without any issues. As for Python 3.3, there were no problems building matplotlib with Visual Studio 2010, but there is no official numpy release supporting Python 3.3 yet. I also have a PIL fork that works on Python 3, which is good for testing.
