Bitfield usage

[websnail]

I think I've found most of the information I need about the new bitfield in these threads:
http://www.phpbb.com/community/viewtopi ... t=bitfield
http://area51.phpbb.com/phpBB/viewtopic ... 26&t=28439
... on phpBB.com but I thought I'd run this by here as well for a reality check too.

Now from what I can tell the bitfield is a neat way of storing the BBCodes that have actually been used in a post so that the system only tries to parse those it knows are in there, reducing the preg_replace() load or whatever their using to handle that.

... and based on this:
http://olympuswiki.naderman.de/Parsing_text

... I don't need to set this bitfield value manually but I do need to store whatever it is along with the "post" data.

That about right?

Use the example here: http://olympuswiki.naderman.de/Parsing_text

Then the bitfield gets generated before parsing.
