- 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.
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.
- ID properties now suopport non utf-8 strings for their values but not their keys.
- moved utility functions into py_capi_utils.c from bpy_utils and bpy_rna.
- import/export paths have to be printed with repr() or %r, so non utf-8 chars are escaped.
- OBJ import/export now work with non utf8 paths. (all exporters and importers need changes like this)
- strip non utf8 chars from new ID blocks (also applies to renaming)
- set the file rename button to allow non-utf8 chars.
- user input gets non utf8 chars stripped all text input other then file paths.
- python has the same limitations, it will raise an error on non utf8 strings except for paths use unicode escape literals so its possible to deal with saving to these file paths from python.
- new string functions
BLI_utf8_invalid_byte(str, len) returns the first invalid utf8 byte or -1 on on success.
BLI_utf8_invalid_strip(str, len) strips non utf-8 chars.
- mesh.add_geometry(v, e, f) --> mesh.vertices.add(tot), mesh.edges.add(tot), mesh.faces.add(tot)
- mesh.add_material(mat) --> mesh.materials.link(mat)
changed material.link so it always adds a material even if it exists in the list, this behavior is good for users but not scripts since it can mess up indicies (some formats may have the same material set twice).
eg:
row.prop_search_self(scene, "active", "keying_sets", text="")
...becomes
row.prop_search(scene.keying_sets, "active", scene, "keying_sets", text="")
This is more flexible since it works for other UI functions too.
eg:
bpy.context.StringProperty(attr='myprop'); del bpy.context.myprop
- made rna StringProperty/PointerProperty & similar into class methods.
- file selector hide option was inverted
- they now share the same code so it wont happen again.
- added id_data to properties so we can do...
matrix = C.object.matrix_world
obj = matrix.owner.id_data # get the original object back.
An example of how this is useful - an importer mixin could define the filepath properties and a generic invoke function which can run the subclasses exec for each selected file.
- Panels and Menus now skip the property check when registering.
- renamed _idproperties_ to _idprops_ in function names, function names were getting very long.
commenting 'blend_factor' for now, its not used.
COLOR and EULER internal pyrna subtypes were causing color type variables to try update euler rotation order.
- raise an exception when python calls is_property_set(name) or is_property_hidden(name) and the property does not exist.
- added BLI_findstring_ptr(), which finds a named item in a listbase where that name is a pointer to a string.
- replaced inline for loops with calls to BLI_findstring_ptr() and IDP_GetPropertyFromGroup().
poll() function is now a static method in python, this is more correct, matching C where the operator is not created to run poll.
def poll(self, context): ...
is now...
@staticmethod
def poll(context): ...
Pythons way of doing static methods is a bit odd but cant be helped :|
This does make subclassing poll functions with COMPAT_ENGINES break, so had to modify quite a few scripts for this.
- removed the immediate option from C/api and now store in python only, when python loads modules it sets it to False.
- unloading a module would clear the entire TypeMap for all modules, only remove the module types that is being unloaded.
- added some checks for bad class registering, report errors rather then crashing.
- exceptions in the __init__ functions were not being checked for and segfaulting
- avoid creating a new BPy_StructRNA instance per function call, use the existing one if the type matches.
F8 key enabled again, useful for script UI development.
- keying set freeing wasnt freeing from all scenes and the builtin list.
- PointerProperty() cant refer to a removed python srna type (fixed in rigify and netrender).
- Added a check for freeing a type used by a PointerProperty but its very slow, makes reloading take ~10sec. Only enabled this in debug mode for now.
Netrender register() function isnt re-registering the property, probably because the module is cached by python and not re-run.
path -> filepath (for rna and operators, as agreed on with elubie)
path -> data_path (for windowmanager context functions, this was alredy used in many places)
Throwing an exception if the strings too long means scripts need to be aware of string lengths and changing a string length in RNA can too easily break scripts.
Instead honor the string length in RNA_property_string_set()
