This has always been the case.

boundaries of the test dataset with grass64release ?


With the test dataset you provided, GRASS 6.4 does generalize the hole
boundaries. I do not have the problem vector of Robert, so I can not
say if the hole boundaries in that vector are generalized or not.


With a make distleaned, svn updated and recompiled grass64relase, using 
the test data and the commands


v.generalize test method=douglas thresh=100 out=test_gen_100 --o
v.generalize test method=douglas thresh=500 out=test_gen_500 --o

I get the attached result (red = 100, orange=500). I don't see any 
generalization in the holes as I do with the same commands in GRASS 7.

Hmm, I do get generalization of the holes in G64 (no local changes).

yes, `grass71_` means grass 71 :-) No changes of startup screen has
been yet backported to relbr70.

Despite all the take this take that discussions and a potential extra
simplified startup it gets into good shape now for RC2.
Should we consider the backport of these changes?

I would like to suggest (facing to RC2, which has been already postponed) to:

1) backport current version of splash screen and startup banner as it's in trunk
2) backport also new version startup screen which has been improved in trunk

Then to release RC2, what do you think? Martin

I checked here with

GRASS 7.1.svn (eu_laea):~ > g.version -ge
version=7.1.svn
date=2015
revision=64482
build_date=2015-01-06
build_platform=x86_64-unknown-linux-gnu
proj4=4.8.0
gdal=1.11.1
geos=3.4.2
sqlite=3.8.8

rpm -qa | grep wxPython
wxPython-2.8.12.0-8.fc21.x86_64

and all is fine (just to confirm).

I dunno at which stage the wxPython 3 integration is in Fedora:
https://fedoraproject.org/wiki/Changes/wxPython3
Perhaps there is a docker image around for quick testing?

Eventhough it's a very small file, may the lighter png file help reduce

No, that doesn't seem to help.

I think that this is more a question of program logic:

When I look at the example splashscreen code at [1], I see that the 
splash screen is defined as a separate class that is called from the 
wxApp's OnInit function and then calls the main GUI from its OnExit 
function. Using the example code here with the 400K version of the 
splash screen works perfectly.


I'm not familiar enough with wxPython and the wxGUI to adapt this 
quickly, but maybe this could inspire some of the wx gurus...

yes, but on the wiki page, they say:

Although this example will work fine, it overlooks the main reason
programmers add a splash screen; to give the user feedback while a program
is loading.

It first displays splash screen for 1 second and then start to load the
main frame. So this would basically make the gui start even longer.
I don't have problems as you describe so it's difficult to test anything. I
still don'y understand, did you have the same problems with the old splash
screen?

+1 for going ahead with the splash screen.

Also, maybe not for RC2 but soon, it would make more sense and be more like 
other programs to have the splash screen come first, followed by the startup 
screen.

[GRASS-dev] Howto use a Python function as error handler in libgis

2015-02-06 Thread Sören Gebbert 
Dear developers,
i am trying to register a Python function as error handler callback
using ctypes in libgis.
I use this code in the temporal framework:


{{{
def error_handler(data):
pass

CALLBACK = CFUNCTYPE(None, c_void_p)
CALLBACK.restype = None
CALLBACK.argtypes = c_void_p

cerror_handler = CALLBACK(error_handler)

libgis.G_add_error_handler(cerror_handler, POINTER(None))
}}}

Unfortunately i get this error:

{{{
Traceback (most recent call last):
  File "/usr/lib/python2.7/multiprocessing/process.py", line 258, in _bootstrap
self.run()
  File "/usr/lib/python2.7/multiprocessing/process.py", line 114, in run
self._target(*self._args, **self._kwargs)
  File

line 759, in c_library_server
libgis.G_add_error_handler(cerror_handler, POINTER(None))
ArgumentError: argument 1: : expected
CFunctionType instance instead of CFunctionType
}}}

Does anyone know what the correct way is to register a Python function
as error handler in libgis?

Any help is highly welcome.

Best regards
Soeren

 Replying to [comment:31 mlennert]:

 > display/d.mon ?

 I was hoping for something which explained the general idea behind what's

 At first glance, this all looks like something of a hack to avoid more

 something.
