Removing data then accessing would allow invalid memory access and often crash.
Example:
import bpy
image = bpy.data.images.new(name="a", width=5, height=5)
bpy.data.images.remove(image)
print(image.name)
Now access to the removed data raises an error:
ReferenceError: StructRNA of type Image has been removed
This is the same level of error checking that was done in blender 2.4x but was made difficult by RNA functions not having access to the PyObject's.
comparing keymaps was too sloppy or too strict, now sloppy keymap comparison works by setting all the operator
properties to their default values if they are not already set, then compare this with the keymap item (ignoring values missing from either one).
... this way any non default keymap setting wont match with an operator menu item which doesnt set this operator at all (a problem sighted in this bug report).
developer notes:
- IDP_EqualsProperties_ex() function adds an argument to treat missing members of either group to act as if there is a match.
- WM_operator_properties_default() function to reset RNA values to their defaults.
- add IDP_spit(), debug only function to print out ID properties.
When this new subtypes is used, then string of property is hidden using
asterisks, e.g.: mysecretpassword -> ****************
This code was reviewed and modified by Brecht. Thanks very much:

This new subtype of string property is intended mostly for Add-on developers
writing Add-on which communicates with some server (http, sql, ftp, verse,
etc.). When this server requires user authentication and user has to type
username and password, then current API didn't allow to type 'hidden' password,
e.g. when you want to demonstrate this script, then everybody can see this
security password. Some examples of Add-on which could use this new subtype:
- On-line database of textures
- Integration of render farm
- Integration of Verse
Security Notes:
- You can copy paste hiddent string of property from text input using (Ctrl-C, Ctrl-V),
but you can do this in other GUI toolkits too (this behavior it is widely used).
- Text of string property is stored in plain text, but it is widely used in other
GUI toolkits (Qt, Gtk, etc.).
Simple examples:
- https://dl.dropbox.com/u/369894/draw_op_passwd.py
- https://dl.dropbox.com/u/369894/blender-password.png
- move object_iterators.c --> view3d_iterators. (ED_object.h had to include ED_view3d.h which isn't so nice)
- move projection functions from view3d_view.c --> view3d_project.c (view3d_view was becoming a mishmash of utility functions and operators).
- some some cmake includes as system-includes.
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.
