Don't "optimistically" parse directory entries #9

Closed natevw closed 10 years ago

natevw commented 10 years ago

Right now we extract everything from every directory entry while iterating. This is one of the things killing performance on Tessel, and is pointless work regardless. We do kinda need the whole long name entries for pretty much all the use cases, but it's actually the main entries that take twice as long to parse (more bitwise fields like dates and times?).

This was [mostly] fixed by https://github.com/natevw/fatfs/commit/37e75c6431875276b20d7c1eaf1f64e85dc31895 [see following bugfix patches].
