Support extending properties as well as methods.
|
|
This isn't so closely related to the RNA API,
it's a way to use the C/Python API to extend RNA types
and can be in it's own file.

Apply clang format as proposed in T53211.

Move bpy_context_module declaration to bpy_rna.h.
|
|
While \file doesn't need an argument, it can't have another doxy
command after it.
|
|
Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

Allows for each workspace to have it's own add-ons on display.
Filtering for: Panels, Menus, Keymaps & Manipulators.
Automatically applies to add-ons at the moment.
Access from workspace, toggled off by default
once enabled, add-ons can be white-listed.
See D3076

Practically all access to enum data is read-only.

The absence of datablock properties "will certainly be resolved soon as the need for them is becoming obvious" said the [[http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.67/Python_Nodes|Python Nodes release notes]]. So this patch allows Python scripts to create ID Properties which reference datablocks.
This functionality is implemented for `PointerProperty` and now such properties can be created with Python.
In addition to the standard update callback, `PointerProperty` can have a `poll` callback (standard RNA) which is useful for search menus. For details see the test included in this patch.

This mainly adds bpy.data.user_map() method, which goes over the whole Main database
to build a mapping (dict) {ID: {users_of_that_ID}}.
Very handy to check and debug ID usages, but could also be really valuable for py addons
creating temporary scenes, or some exporters, etc.
Note: current code in master's libquery misses some IDs (and reports some it should not,
like nodetrees), this is fixed in id-remap but still needs serious review before going to master.
This basically means that current bpy.data.user_map() **will not** report a complete and exhaustive
state of dependencies between IDs. Should work OK in most cases though.
Original work/idea comes from id-remap branch, was heavily reworked by @campbellbarton
and myself for master.

them internally.
- yes, this does break scripts, but the api is marked experimental.
ED_region_draw_cb_activate() adds a callback to a region type whereas the api made it look like the callback was being added to the region instance.
Use a class method on bpy.types.Space to manage region drawing, eg.
was:
self._handle = context.region.callback_add(draw_callback_px, args, 'POST_PIXEL')
is now:
self._handle = bpy.types.SpaceView3D.draw_handler_add(draw_callback_px, args, 'WINDOW', 'POST_PIXEL')

code and then referenced from python.
now further access in python gives an exception at the line when the freed data is accessed.
|
|
C with gcc.
helps for finding unused functions and making functions static, also did some minor code cleanup.
|
|
|
|
without the underscores these clogged up the namespace for autocompleation which was annoying.

nothing to effect translations.
|

had 'WITH_PYTHON_SAFETY' enabled which was using different iterators (which dont crash), now there on by default.
made headless and no-python configurations work again and added --factory-startup to doc building command.
|
|
this is only used for doc generation and it makes _every_ blender/python instance 4 bytes bigger - vertex/bezier point/object/scene/group etc.

method, gives small speedup drawing buttons since every layout.prop/col/operator/menu etc creates and throws away one of these.
|

gives warnings with variable length args.

compile time option which enables extra safety checks.
since this is noticeably slower I rather not enable by default yet.

fix for crash when iterating over a collection which allocates the collection and frees on when finished.
The ability for BPy_StructRNA to hold a reference to other PyObject's was added to support this.
|
|
Previously the api just converted the collection to a list and got the iterator from the list to return.
This has the advantage that it uses minimal memory on large collections where before it would make an array.
Though the main reason for this change is to support a bugfix for collections which free memory when they are done, this currently crashes the python api since once the list is built, the data is freed which is used by the list items in some cases (dynamic enums for eg).

Second method for not having python crash blender on invalid access (ifdef'd out ATM, so no functional change).
This uses a weakref list per ID, and invalidates all members of that list when the ID is freed.
the list is not stores in the ID pointer but using a hash table since storing python in DNA data is not acceptable.
This is more correct then the previous method but shows down execution of scripts significantly since its always adding and removing from lists when data is created and freed.
|
|
freed ID's.
This uses pythons GC so its no overhead during runtime but makes removing ID's slower.
Commented definition 'USE_PYRNA_INVALIDATE_GC' for now, so no functional change.
|
|
access will raise an error.
|
|
|
|
ifdef'd out weakref for blender/py api, worth testing to see if it adds much overhead.
|
|
|
|
no functionality change.

|
- 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.
|
|
warnings.
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.

obj.path_resolve("location[1]")
- corrected comment from previous commit

working.
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.
|
|
functions will only be shown for types that support it.
- moved array attributes into array properties - saves 8 bytes per allocated non-array property.
