Use this to raise errors when assigning a string property fails even though the value to assign *is* a string.
Before:
TypeError: bpy_struct: item.attr= val: Object.name expected a string type, not str
After:
TypeError: bpy_struct: item.attr= val: Object.name error assigning string, UnicodeEncodeError('utf-8' codec can't encode character '\udce9' in position 23: surrogates not allowed)
- rearrange structs to work for 64bit
- define all vars before goto's
- ifdefs for qsort_r/qsort_s
- dont cast pointers to int only for NULL checks
- dont printf STR_String directly, get the char pointer from it
also minor change to gpu py module, no need to pass empty tuple to PyObject_CallObject, can just be NULL
shader = gpu.export_shader(scene,material)
Returns the GLSL shader that blender generates to produce the visual effect
of material in scene for the purpose of reusing the shader in an external engine.
This function is meant to be used in a material exporter so that the GLSL
shader can be exported entirely. The return value is a dictionary containing the
shader source code and all associated data.
The full documentation is under sphinx.
Warning: there has been an API between the patch and this commit:
uniform['lamp'] and uniform['image'] now return python reference to
ID block instead of ID name as before. The X3D exporter that uses this
function must be adapted.

--- text from the patch.
Recently Campbell Barton added callback functionality for Python's usage, but this only includes pre- and post-render callbacks. There are no callbacks for the duration of the render. This patch adds the few lines required for executing a callback while Blender Render is working. The callback resides in the rendering pipeline stats function, so whenever statistics are printed, the callback is executed. This functionality is required if one wants to:
1) Observe what is happening while Blender is rendering via the command line
2) Add custom statistics that Blender prints while the renderer works
3) The user wants to continue executing his Python script without the code halting at bpy.ops.render.render()
Personally I'm currently using this for printing out more detailed progress reports at Renderfarm.fi (such as CPU time, time spent rendering, total progress in regards to the entire rendering process). Tested on Windows, Linux and OS X.
Example on how to use the callback:
def statscall(context): print("Thanks for calling!")
bpy.app.handlers.render_stats.append(statscall)
bpy.ops.render.render(animation=False, write_still=True)
* replace by BLI_snprintf in various places, note _snprintf on windows
does not properly null terminate the string.
* fix overflow in sequencer proxy code due to buffer being smaller than
specified size.
* fix some usage of snprintf as strcpy, this is will go wrong if the
string contains % characters.
* remove BLI_dynstr_printf function in gpu module, use BLI_dynstr_appendf
- dont use hash lookups in this case because converting the string to unicode and doing a hash lookup is slower then looping over the keys and comparing (which avoids creating and throwning away a unicode string).
existing check for driver to use GIL was not thread safe and could cause, details in the report.
This bug was caused by a check to avoid hanging, a fix for [#27683] that worked in 2.4x because the UI didn't use python to draw while rendering.
Apply a different fix for [#27683], when calling an operator, call PyEval_SaveThread(), then PyEval_RestoreThread() so the GIL can be aquired by threads started by the operator - in this case bake starting a thread that evaluates drivers.
Python:
* adds bpy.app.handlers which contains lists, each for an event type:
render_pre, render_post, load_pre, load_post, save_pre, save_post
* each list item needs to be a callable object which takes 1 argument (the ID).
* callbacks are cleared on file load.
Example:
def MyFunc(scene): print("Callback:", data)
bpy.app.handlers.render_post.append(MyFunc)
C:
* This patch adds a generic C callback api which is currently only used by python.
* Unlike python callbacks these are not cleared on file load.
