- rename rna collection structs Main prefix to BlendData: eg, MainObjects --> BlendDataObjects
- printing python collection now prints its type (when available)
- renamed shadowed vars in bpy_rna.c.
- when making functions static I also made debugging/test functions static, reverse and add definitions to headers instead.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
- KeyingSetInfo classes are now collected like Panels, Operators etc so bpy.utils.register_module() can be used.
- move bpy.types.register() to bpy.utils.register_class
- operators which reload G.main would crash blender if called from python and then accessed bpy.data.*
- WM_read_homefile_exec was setting the contexts Scene to NULL as a signal for the event system, this didnt work in background mode, crashing when property update functions expected scene to be set.
- now writing to RNA is disabled when inside render() call.
- disallow calling operators when writes are disabled.
Rendering runs in a thread so running operators from the thread is not safe unless rendering becomes a blocking operator again.
disable getattr metaclass forwarding attributes from the python class, eg:
bpy.types.Scene.foo != bpy.types.Scene.bl_rna.properties['foo']
... This was convenient but too tricky to properly maintain with attribute assignment and attributes defined within the class.
avoid doubles in dir() by converting to a set and then back to a list.
- values were added to both the classes __dict__ as well as the internal StructRNA.
- made properties available from the type since this is where the python api assigns them:
>>> bpy.types.Scene.frame_start
<bpy_struct, IntProperty("frame_start")>
- rename RNA_struct_type_properties() -> RNA_struct_type_properties(), added RNA_struct_type_find_property()
- avoid looping over the entire collection unless a negative index is used.
- dont use the get index function for building the slice list, instead loop over the collection until the stop value.
Speedup for getting collection indices, avoid getting the collection length unless a negative index is given. This avoids a loop over the entire collection in many cases.
Speedup for getting collection slices by detecting collection[:] and internally calling collection.values(), this gives a big speedup with some collections because each slice item would loop over the list until that index was found.
Rough test with 336 objects.
- getting index of listbase collection ~ 5.0x faster
- getting index of array collection ~ 1.15x faster
- getting slices of listbase collections ~ 34.0x faster
- getting slices of array collections ~ 1.5x faster
- Adding drivers from the UI (not from py-scripts though) will now
automatically add a "Transform Channel" driver variable to the newly
created drivers. This makes setting up drivers a bit more convenient
for the most commonly used case.
- Drivers now report their errors using the Reports system instead of
writing these directly to the console.
- Clarified some comments to be more insightful about the "why's" of
some design decisions, and related formatting/cleanup tweaks
- Reduced scope of "path" vars to just the scope they're required in
- Removed some unused defines from a failed experiment in the original
Keying Sets code ("templates" and "template flags") which was
superseeded by the more flexible + nicer "Builtin KeyingSets"
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.
