For details there are unit tests and api example usage.

This way blender player can easily use BPY_thread_save/restore.
Not so much important for master branch, but crucial to solve
linking issues in threaded depsgraph branch.
- Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS macros cannot be used here, because the Py_BEGIN_ALLOW_THREADS causes a crash when quitting Blender.
- The low level function PyEval_ReleaseLock() is used assuming the Python library was built with multi-threads support.
This means calling invoke operators from python in states that dont support will give a meaningful error message.
also reduce context lookups when polling.
- script execution is off by default
- if a blend file attempts to execute a script
this shows a message in the header with the action
that was suppressed (script/driver/game-autostart) and 2 buttons to either reload the file trusted, or to ignore the message.
- the file selector will always default to use the trust setting in the user preferences,
but reloading an open file will keep using the current setting (whatever was set before or set on the command-line).
- added SCons setting WITH_BF_PYTHON_SECURITY, this sets the default state for the user prefereces not to trust blend files on load.
... this option was in CMake before, but always off, now its enabled by default for SCons and CMake, and forced on in CMake for now.
- enable site-packages for bundled python distrobution, py3.2 had a problem where it would try to parse headers we didnt include, but its resolved now.
- workaround for glitch I was having on arch-linux where lib64 would be be used for the bundled python directory when it was just a symlink.
- bpy.path.extensions_image
- bpy.path.extensions_movie
- bpy.path.extensions_audio
eg:
if os.path.splitext(filename)[1].lower() in bpy.path.extensions_image:
... we have an image ...
- add sequence.update(data=False) function.
- made some sequence vars editable.
- correct some comments.
also rename rna function sequence.getStripElem() --> strip_elem_from_frame()
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.
