[matplotlib-devel] MacOS X backend possible leak
Paris (U.E.), le 28/01/2011
Bonsoir
I am trying to code a specialized data visualization technique
(quite old and mostly forgotten), which I will release under the Python
Software License. I want to customize the navigation bar read-out so as to give
more relevant information than cartesian coordinates. I am not quite there yet,
and may be missing a few things, but I have run into a problem.
If I try to output a specific string to the navigation bar,
using
fig.canvas.toolbar.set_message("Toto")
then sure enough the correct message appears in the right place. However, using
the MacOS X backend, I get the leak message reproduced at the end of this
message. I would much prefer to code in a backend-agnostic manner. Could
someone please point me in the right direction?
Merci
Hubert Holin

Re: [matplotlib-devel] I have a Mac!
Paris (U.E.), le 17/08/2013
Bonsoir
Both on my old (PPC) Mac at work and on my (somewhat) more
recent (Intel) Mac at home, I install from source (no homebrew, Fink, MacPorts
or whatever, though these are great to-have items!): latest stable release for
Python itself (2.7 & 3.3), the rest from repositories. I guess I am lucky not
to have run into a wall, or perhaps just plain stubborn… There is perhaps a
lack of functionality (I have not delved into IPython notebooks, and Tcl/Tk
usually is a nightmare for my old box), but for what I have, or want, to do, it
just works. I should add that at work I am behind a really "thick" firewall, so
I pay close attention to all dependencies and install these before what depends
on them (obviously!, though there are (partly) circular references which
require more work); I do sometimes have to download at home and transfer via
key…
At any rate, a well-documented (I just whent ahead and kept no
notes… sorry!) installation roadmap would really be a usefull thing.
And thanks for the great woks which goes into matplotlib (it really
made my life more bearable)!

Re: [matplotlib-devel] I have a Mac!
Paris (U.E.), le 17/08/2013 Bonsoir Building for various architectures than one is on, on the Mac, is something I regretfully bought into (Apple in the beginning told us to go for it) but latter found out to be a useless hassle (Apple silently removing PPC64 dev tools anybody?

[matplotlib-devel] Dealing (gracefully?) with problematic fonts
Paris (U.E.), le 08/12/2014 The transition to MacOS X 10.10 (and more precisely 10.10.1) is proving quite problematic. One problem I am currently stuck with prevents me from using matplotlib. Whether using matplotlib 1.4.2 and freetype 2.3.12 (combination A) or matplotlib 59eda228e6a77e842c63078c3af870868120e70c and freetype 2.5.3 (combination B), importing matplotlib.pylab results in a crash. I have not tried other combinations… In the case of combination A, the crash occurs because FT_Set_Char_Size (ft2font.cpp, line 909) returns an error because of the font “/System/Library/Fonts/Apple Color Emoji.ttf” and an uncaught exception is then thrown on line 916. In the case of combination B, the crash occurs because FT_Set_Char_Size (ft2font.cpp, line 508) returns an error because of an unidentified font (I could not quickly find a way, in this version of the file, to access the name of the font being tested…) and an uncaught exception is then thrown on line 510. As the font “/System/Library/Fonts/Apple Color Emoji.ttf” is a system font, and therefore off-limits to most users, it would be unadvisable to mess with it (including removing it from the system), and even though I would personally be quite unlikely to use it in conjunction with matplotlib, our Japanese colleagues might see things differently. At any rate, it does not seem to be corrupt (it may be complex, though, as TypeTool displays it differently from Font Book, which is hardly surprising as it is a *color* font…). Barring a more sophisticated treatment of such fonts, could it be possible to catch the exception, just not take these fonts into account, and move on to the rest of the work? I have not grasped the organisation of the source that well to know where to propose a patch. Any hint welcome!
