matplotlib-devel Mailing List for matplotlib

All,
I think the git migration deserves its own thread on the devel list, so 
here is a start.
The full svn repo includes much more than just matplotlib: also course, 
htdocs, py4science, sample_data, sampledoc_tut, scipy06, toolkits, and 
users_guide. Before moving matplotlib, I think we should have a clear 
plan as to how these other parts are going to be handled. Will some or 
all remain as the active parts of the svn repo, with matplotlib somehow 
marked as invalid? Will some or all get their own github repos? My 
primary interest here is toolkits/basemap, but I am sure other good 
stuff is in there.
Before the transition, it would be good to have a pointers to the 
simplest possible docs illustrating typical workflows after the 
transition; maybe one for present developers with svn access, and 
another for occasional contributors.
Does it makes sense to retain the entire history in the new github repo, 
or would it be just as well to start from a later point so as to reduce 
the size? The entire history could still be available in a separate 
read-only repo, or fossilized in svn on sourceforge, or in my hg mirror. 
 (Andrew's repo, at just under 200MB, is not prohibitively large by any 
means, but it is a bit hefty.)

I followed your instructions and re-built, and I get the same error.
I also ran "nm ft2font.so" and I get results that look like this:
 U _FT_Attach_File
 U _FT_Done_Face
 U _FT_Done_FreeType
 U _FT_Done_Glyph
 U _FT_Get_Char_Index
 U _FT_Get_First_Char
 U _FT_Get_Glyph
 U _FT_Get_Glyph_Name
 U _FT_Get_Kerning
 U _FT_Get_Name_Index
 U _FT_Get_Next_Char
 U _FT_Get_PS_Font_Info
 U _FT_Get_Postscript_Name
 U _FT_Get_Sfnt_Name
 U _FT_Get_Sfnt_Name_Count
 U _FT_Get_Sfnt_Table
 U _FT_Glyph_Get_CBox
...
According to the nm man page, the "U" means that "_FT_Attach_File" is undefined.
Is there some sort of switch in the makefile that will define these symbols?

Using the svn build from 2-25:
matplotlib.__version__ = 1.0.svn
Python from Enthought:
Python 2.6.4 -- EPD 6.0.0 (64-bit)
I get the following errors when I try to import ft2font:
Traceback (most recent call last):
File "./testme.py", line 3, in <module>
from matplotlib import ft2font
ImportError:
dlopen(/Library/Frameworks/EPD64.framework/Versions/6.0.0/lib/python2.6/sit

Expected in: flat namespace
in
/Library/Frameworks/EPD64.framework/Versions/6.0.0/lib/python2.6/site-packa
ges/matplotlib/ft2font.so
My code looks like this:
#!/usr/bin/env python
from matplotlib import ft2font
print 'Hello world'

Fixed in svn r8170. Thanks for the report.

Hi,
 There is a typo in the matplotlib line.py file in function get_xydata
line 662
it should be self._invalidx instead of self.invalidx
(missing leading underscore)
Regards,
David
