Current status

Targeted release: Fedora 22
Last updated: 2014-12-16
Tracker bug: <will be assigned by the Wrangler>

Detailed Description

This change proposal aims to get wxPython 3.0 (Python bindings for the wxWidgets GUI library) packaged and into Fedora. Currently Fedora has wxPython 2.8 which has not been updated since 2011. The plan is to make replace wxPython 2.8 with wxPython 3.0 and fix any dependent packages that may have issues with wxPython 3.0.

Benefit to Fedora

This change brings a more modern wxPython to Fedora, including support for GTK3 (currently wxPython 2.8 uses GTK2). Additionally, it moves Fedora to a supported version of wxPython.

Scope

Proposal owners:

Update existing wxPython package to wxPython 3 and ensure it builds/works in Rawhide.
In conjunction with the wxPython dependent package maintainers, test dependent packages to ensure they work correctly with wxPython 3. Assist with porting issues.

Other developers:

For maintainers of packages that depend on wxPython: test the dependent packages to ensure they work correctly wxPython 3.0. Update the dependent packages as needed to support wxPython 3.0. The API hasn't changed much between wxPython 2.8 and 3.0, but some changes may be required.

Release engineering: None

Policies and guidelines: None

Upgrade/compatibility impact

User written wxPython applications may require a small amount of porting, but mostly wxPython 2.8 is forward compatible with wxPython 3.0.

How To Test

No special hardware or data is required. To test, one would install a wxPython-dependent package and verify that it functions as it did with wxPython 2.8 (other than possible GTK2 vs GTK3 UI differences).

User Experience

For the most part, users will not notice any changes, other than the fact that wxPython applications will now look like GTK3 applications instead of GTK2.

Dependencies

The packages below depend on wxPython. The wxPython 3 test/fix status will be tracked below.

PyPE, PythonCard, bibus, congruity, cura, cycle, gitso, gnumed, gnuradio, grass, gtkwhiteboard, hugin, londonlaw, mMass, metamorphose2, openstv, peppy, phatch, plater, pronterface, pyhoca-gui, pymol-wxpython, pyobd, python-matplotlib-wx, python-pyface-wx, python-squaremap, rurple, sidc-gui, sk2py, spe, taskcoach, timeline, wammu, winpdb, wxGlade

Status
Pie	Danish
Cheese	Yogurt

Contingency Plan

Contingency mechanism: remove wxPython 3.0 and revert any dependent packages back to wxPython 2.8
Contingency deadline: Beta Freeze
Blocks release? No
Blocks product? No
