WM_operator_poll() could fail in cases WM_operator_name_call() would succeed because calling the operator would setup the context before calling poll.
this would result in python raising an invalid error or menu items being greyed out.
now python can also check with an operator context:
bpy.ops.object.editmode_toggle.poll('INVOKE_SCREEN')
from mathutils.geometry import PolyFill
I couldn't find a way for python's inittab to do this so just inserting mathutils.geometry into sys.modules manually.
having the blend file as a part of the __file__ variable is not essential, this is fixed in python 3.2 so add an ifdef and don't use the blend file path for py older then 3.2.
Simple python benchmark shows this to be about 3x faster in the case where an update isn't needed.
This also speeds up rna function argument parsing, since each arg in a function call did 2 string lookups on the context which were never needed.
applied to python api and exotic.c, removed some args being passed down which were not needed.
keyword args for new mathutils types were being ignored when they should raise an error.
- bpy.app.debug can now be set, removed bpy.data.debug (since this is not blendfile data)
- added bpy.app.tempdir, this is needed because the userpref temp dir isn't always set, $TEMP may be used instead and scripts need temp dir access.
now addon path is created using the same path functions and selecting where to save the startup.blend
also made some minor changes to path handling funcs.
- fixed WM_OT_context_cycle_int was causing problems with int overflow, now it cycles properly.
- rename QUOTE macro to STRINGIFY_ARG, and added STRINGIFY, which is used more often since it gives the value as a string.
This means we can do operator drawing without passing self.properties as an argument.
while this check if quite specific, if this gives problems later on we should probably change operators not to try to mix an operator and its properties, it looks nice to a scripter but internally is not easy to manage.
* Fix var declaration in bpy_interface.c
* Remove forward declarations from py_capi_utils.h: they are unnecessary and break compiles (there were probably many warnings about this during compile with GCC).
- BKE_add_image_extension now sets the extension rather then appending. (no more image.jpg.tga)
- py/rna functions which have no return value now raise an error if a non-None value is returned.
- added back the red-alert flag so buttons can have a red highlight if somethings wrong.
The reason this didnt work is all sibclasses of pythons type() or PyType_Type in C, have to have their size set to sizeof(PyHeapTypeObject) rather then sizeof(PyTypeObject) as you might expect.
This is strange since its not a heap-class (defined in pythons runtime), but a static C type, so Im not sure about this, and cant find any documentation but it seems to work ok.
- operator properties are now converted into python property() class members which bypass the operator 'properties' member.
self.properties.mysetting
... can now be written as ...
self.mysetting
- fix for error reloading rigify
eg:
bpy.types.Scene.myprop = BoolProperty()
note, this uses an ugly python metaclass, this should be replaced with a C implimentation which is included but commented out, causing crashes in pythons GC which gives no hint as to where the bug comes from.
- rna internal deferred properties now store the functions as PyObjects rather then C function pointers
- Property functions now allow the first non keyword argument to be a class.
Setting the classes __dict__ member directly didnt update the types slots (python internal type stuff used with subclassing), so class.bl_rna was returning an incorrect value.
Set the value using typical python setattr command.
cant test if this fix solves the problem matt is having but it at least fixes an error caused by classes created in exec(),
when the properties pointers were copied the hash key still referred to the python object which could be freed. in most cases this wouldnt happen (would be kept in bytecode) but with exec() the property string is freed immediately.
