Datablock names

[Grogyan]

First a big round of applause for the Devs and Paradox.

Just recently I read in the SVN log for Blender that a fix has been done to allow longer datablock names.

Datablock name lengths have been a problem for a while, especially back when sounds were added to PyPrp, but since then topics were created to fix the problem in PyPrp, but in actual fact the problem was in Blender, now it has been fixed, and should be in a build from http://www.graphicall.org

Said fix was immediately reverted by a Blender dev

Did they give a reason? O.o

The patch that I contributed did not change the length of datablock names. Instead, when trying to access a Scene datablock via Python using the Get() function, it would chop the input to the datablock maximum.

However, as the Blender devs stated, you cannot have a guarantee when you create a datablock that Blender will give it exactly the name that you specify, so cutting down the name on a Get() function could still introduce errors and doesn't really resolve any issues. It is up to the script itself to make sure that it gets the datablock that it needs.
