Package: cecilia Version: 5.0.9-1 Severity: serious Justification: blocks the on-going wxpython3.0 transition Tags: sid jessie User: freewx-ma...@lists.alioth.debian.org Usertags: wxpy3.0 Control: block 755757 by -1
I missed this package in my previous checks, as while it uses the wx API, it doesn't seem to have any sort of dependency on python-wxgtk2.8 or indeed any wx package (it'd be useful for transitions, and I think also for users, to add at least a 'Suggests: python-wxgtk3.0'). Starting cecilia from unstable with python-wxgtk3.0 installed, I get the following output, and it doesn't seem to actually start up correctly: Preferences file not found. pyo version 0.7.0 (uses single precision) WxPython is not found for the current python version. Pyo will use a minimal GUI toolkit written with Tkinter. This toolkit has limited functionnalities and is no more maintained or updated. If you want to use all of pyo's GUI features, you should install WxPython, available here: http://www.wxpython.org/ ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side ALSA lib pcm_route.c:947:(find_matching_chmap) Found no matching channel map ALSA lib pcm_route.c:947:(find_matching_chmap) Found no matching channel map ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/cecilia/Resources/splash.py", line 70, in OnPaint font.SetPixelSize((15,15)) File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_gdi.py", line 2313, in SetPixelSize return _gdi_.Font_SetPixelSize(*args, **kwargs) wx._core.PyAssertionError: C++ assertion "IsOk()" failed at ../src/gtk/font.cpp(337) in GetPointSize(): invalid font Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_misc.py", line 1367, in Notify self.notify() File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_core.py", line 16866, in Notify self.result = self.callable(*self.args, **self.kwargs) File "/usr/lib/python2.7/dist-packages/cecilia/Resources/splash.py", line 78, in OnClose self.callback() File "/usr/bin/cecilia", line 68, in onStart ceciliaMainFrame.onOpen(os.path.join(MODULES_PATH, category, file), True) File "/usr/lib/python2.7/dist-packages/cecilia/Resources/CeciliaMainFrame.py", line 236, in onOpen CeciliaLib.openCeciliaFile(self, event, builtin) File "/usr/lib/python2.7/dist-packages/cecilia/Resources/CeciliaLib.py", line 584, in openCeciliaFile getVar("audioServer").openCecFile(cecFilePath) File "/usr/lib/python2.7/dist-packages/cecilia/Resources/audio.py", line 1660, in openCecFile CeciliaLib.getVar("mainFrame").onUpdateInterface(None) File "/usr/lib/python2.7/dist-packages/cecilia/Resources/CeciliaMainFrame.py", line 326, in onUpdateInterface ceciliaInterface = CeciliaInterface.CeciliaInterface(None, title='Interface - %s' % title, mainFrame=self) File "/usr/lib/python2.7/dist-packages/cecilia/Resources/CeciliaInterface.py", line 52, in __init__ self.controlPanel = Control.CECControl(self, -1) File "/usr/lib/python2.7/dist-packages/cecilia/Resources/Control.py", line 108, in __init__ self.sizerMain.Add(Separator(self, (230,2), colour=BORDER_COLOUR), 1, wx.EXPAND) File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_core.py", line 14453, in Add return _core_.Sizer_Add(*args, **kwargs) wx._core.PyAssertionError: C++ assertion "Assert failure" failed at ../src/common/sizer.cpp(1401) in DoInsert(): too many items (4 > 1*3) in grid sizer (maybe you should omit the number of either rows or columns?) I've included the standard information from the other mails I filed earlier below: We're aiming to migrate the archive to using wxpython3.0 instead of wxwidgets2.8, and hope to drop wxwidgets2.8 before jessie is released. This transition is already underway, and is being tracked by the release team here: https://release.debian.org/transitions/html/wxpython3.0.html The wxPython 3.0 API mostly adds to the wxPython2.8 API. Many packages work with wxPython 3.0 without any changes, but there are a few incompatibilities. For example, wx.Color is no longer supported as an alias for wx.Colour, and some constants which were deprecated in 2.8 have been removed. All the removed constants I'm aware of were set to 0 in wxPython 2.8, so removing them is still compatible with 2.8. To assist updating to wxPython 3.0, I've put together a script which will help make the mechanical changes required. This is in a git repo on collab-maint along with a README about using it and updating packages for wxPython 3.0 in general: http://anonscm.debian.org/cgit/collab-maint/wx-migration-tools.git The script has some options to control the sorts of changes it makes - see the README and --help output for more information - you can view the latest version of the README online here: http://anonscm.debian.org/cgit/collab-maint/wx-migration-tools.git/tree/README I've developed this script by trying to convert 20+ packages. Please try it out on your package - in many cases, it should be enough to get your package working (if it doesn't already) - if it does, please upload (and close this bug). If the script doesn't do the job, please let me know (or improve the script if you can figure out what it needs to do to get your package working). Another issue you may hit is that wxWidgets 3.0 now defaults to enabling its "WXDEBUG" checks for incorrect API usage, so some applications will emit scary sounding "assertion failures". These are unlikely to actually be new, just in a default build of 2.8, such incorrect uses were handled quietly behind the scenes. Sometimes these are easy to fix, but if not you can easily patch the application to tell wx 3.0 to handle them in the same way wx 2.8 does - details of how to do so are in the README: http://anonscm.debian.org/cgit/collab-maint/wx-migration-tools.git/tree/README I'm happy to sponsor uploads for this transition, though if you have an active sponsor already check with them first - I don't want to tread on anyone's toes.
