this breaks and causes bug: [#32720], where sys.stdout becomes invalid and print() does nothing.
On investigation - python is not getting the environment variable from blender (aparently because its a DLL?) so this should be resolved rather then overwriting sys.stdout.
nice obscure case, when a script executes, frees its self (by loading a file for eg), then has a python error.
... in this case blender would fetch the python exception and attempt to move the cursor in the freed textblock to the error line, crashing blender.
undo.
The way this got updated from the context is a bit unreliable, and for handlers
the update couldn't happen because there is no context passed in. Now it's
updated from setup_app_data, which is where the change actually happens. I left
in the other updates to be sure but they should not be needed anymore.
while. This may not fix all cases but should at least solve the issue when
rendering with cycles.
The cause was a race condition on C->data.recursion, with multiple threads
accessing context at the same time. Cycles itself does not access context
from the render thread, but the bpy api would do a context update for any
callback in case e.g. a new file got loaded. Disabled that now in non-main
threads.
The ideal solution would be to not allow any context access at all from threads
but that's not so simple to implement, especially not this close to release.
--debug
--debug-ffmpeg
--debug-python
--debug-events
--debug-wm
This makes debug output easier to read - event debug prints would flood output too much before.
For convenience:
--debug-all turns all debug flags on (works as --debug did before).
also removed some redundant whitespace in debug prints and prefix some prints with __func__ to give some context.
Not all file formats/calls are supported yet. It will be expended.
Please from now on use BLI_fopen, BLI_* for file manipulations.
For non-windows systems BLI_fopen just calls fopen.
For Windows, the utf-8 string is translated to utf-16 string in order to call UTF version of the function.
corrently allows to create and loop over verts/edges/faces, access selection and selection modes.
this is still WIP, access to face, edge verts is still missing, no access to UV's, no access to editing operations yet.
When the api is ready it will be documented by sphinx like mathutils, blf, aud.
The rendering device is now set in User Preferences > System, where you can
choose between OpenCL/CUDA and devices. Per scene you can then still choose
to use CPU or GPU rendering.
Load balancing still needs to be improved, now it just splits the entire
render in two, that will be done in a separate commit.
- rename 'bcycles' --> '_cycles', since this is the python convention when a py module uses a C module internally.
- use macros for returning None
- make with_osl an attribute rather then a function.
- changes methods METH_VARARGS --> METH_O when single args are used.

Tracker description
*******************
The current python noise module included with Blender has yet to be updated to the new Py API. This patch does so, with the following major points:
- The noise module has now been moved to a submodule of mathutils, it can be accessed by mathutils.noise. It was moved from it's own module as it will now return mathutils types and also have greater visibility to the user.
- All functions which return vectors will now return mathutils.Vector types to be consistent with the rest of the API. Previously (x, y, z) tuples were returned.
- A different implementation of random_unit_vector is now used, this allows 2D, 3D and 4D vectors to be returned. Previously only 3D was possible.
- Some function names have been changed to remove ambiguities and make naming consistent within the module. noise.vector is now noise.noise_vector and noise.vl_vector is now noise.variable_lacunarity
- Doc strings have been updated to be compatible with auto docs.
- Code style and internal naming has been changed to match the conventions in other mathutils code.
Thanks,
Andrew
without this printing a unicode string may raise an error which is a real pain especially since script authors often forget this and print the path of a file for example on export which can make a script fail outright when writing to paths with certain encodings.
