All the driver-specific code in `fcurve.c` has been moved into a new file
`fcurve_driver.c`. The corresponding declarations have been moved from
`BKE_fcurve.h` to `BKE_fcurve_driver.h`.
All the `#include "BKE_fcurve.h"` statements have been investigated and
replaced with `BKE_fcurve_driver.h` where necessary.
No functional changes.
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This is often invalid, outdated or misleading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.
Limit to a restricted set of built-ins, as well as the math module.
Also restrict of op-codes, disallowing imports and attribute access.
This allows most math expressions to run
without any performance cost once the initial check is done.
See: D1862 for details.
Drivers can use this to refer to the data which the driver is applied to,
useful for objects, bones, to avoid having to create a variable pointing to its self.
Support for driver variables that don't resolve to numbers, eg:
objects, bones, curves... etc.
Without this, Python expressions to access this data needed to use an absolute path from `bpy.data`,
however this is inconvenient, breaks easily (based on naming) and wouldn't set the dependencies correctly.
- 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.

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
- no need to link to scenes when using a frame from the pydriver, this made linking rigs for eg, quite messy.
- advantage that we get subframe values (where scenes from was fixed to a whole number).
