This is ifdef'd and may be disabled later on, or only enabled in debug mode.
This applies to setting any RNA value that has an ID and is not a screen or window-manager datablock.
Some addons break this rule and need fixing but from my tests blender UI scripts are ok.
- pep8 script was giving an error on non utf8 scons source files.
- use PyList_SET_ITEM macro when list type is ensured.
- all mathutils types use subtypes to create new types when available.
- use defines MAT3_UNITY, MAT4_UNITY to initialize unit matrices.
- when python operators fail to execute they were returning RUNNING_MODAL, now return CANCELLED
now when an operator fails it gives an error popup as well as a message in the terminal.
* Keyframing operators now use the reports system for displaying all its error messages.
- The benefit of this is that users no longer need to check the console for error messages if keyframing fails.
- Unfortunately, reports are not currently viewable in any space/view in Blender, so...
* Added a temporary operator (UI_OT_reports_to_textblock), which can be accessed in the UI from the button which appears in place of the icon when more than one report exists. This dumps the current list of reports to a textblock "Recent Reports", from which they can be viewed.
This isn't really nice, but at least we now have a way to view these again, which makes debugging some things a pain.
* Bugfix #24606 - when trying to add keyframes to F-Curves with F-Modifiers already which alter the curve significantly enough that the keyframes will have no effect, there are now warnings which aim to alleviate any confusion.
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.
- 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.
- 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.
