* Windows installer not working for non-admin users and multiple users
* Addon scripts not installing next to user configuration
* Portable install not being taken into account in all places
The main problem was the windows installer was installing system scripts in
AppData next to the user configuration directory, which is not shared between
users. Now these are installed in ProgramFiles, and only addon scripts added
by the users go to AppData.
On all platforms, addon scripts were sometimes getting installed between
system scripts, because the scripts folder in the executable directory was
given precedence over the user configuration folder, that is no longer done
now. So addons now behave like user configuration, they are preserved even
if you download a newer build of the same blender version.
If you have an installation of 2.57 on windows, the addon install location
will not change until we do the version bump to 2.58, to avoid conflicts with
the existing the installed 2.57 version.
The old behavior of giving precedence to the local folder was done to support
portable install, where all configuration is written to the local folder. This
is now implemented differently: if and only if a "config" folder exists in the
local folder, portable install will be assumed, and files will only be written
to that local folder.
CMake build option WITH_PYTHON_MODULE, will build ./bin/bpy.so
This allows 'bpy' to be imported from python or other applications/IDE's which embed python, eg:
python -c "import bpy ; bpy.ops.render.render(write_still=True)"
This runs in background mode and has similar restrictions to running a script:
blender --background --python test.py
TODO:
- install to site-packages with blender scripts
- add support for imp.reload()
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
- python 3.2 does 'import site' on startup which now tries to parse pyconfig.h which isn't copied. so for now just run without importing 'site', alternative would be to copy the header file for posix systems.
- cache PYTHON_VERSION variable so it can be set to 3.2, needed for copying python installation's other then 3.1.
calling
bpy.ops.wm.read_factory_settings()
... would clear a scripts namespace if running directly, not in a module.
Fix by backing up and restoring the __main__ module.
Also found BKE_reportf wasnt printing all reports in background mode as BKE_report() was doing.
This is an annoying but which isn't a problem for Python because they don't execute multiple scripts, one after another (there is one __main__ and everything else is a module).
So when the __main__ module in sys.modules is overwritten, it decref's the module and clears the dictionary with _PyModule_Clear(), even though the modules dictionary is still in use.
Strangely this problem only happens with Python3.1.1 and Python3.2x svn but not 3.1.2
This commit restores the namespace after _PyModule_Clear() sets all its values to None.
from mathutils.geometry import PolyFill
I couldn't find a way for python's inittab to do this so just inserting mathutils.geometry into sys.modules manually.
having the blend file as a part of the __file__ variable is not essential, this is fixed in python 3.2 so add an ifdef and don't use the blend file path for py older then 3.2.
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.
