[opendemo-devel] ring-buffer is ready

[Dr. U. G. <Uwe...@ph...>]

Hello!

I finally found the small bug in my ring-buffer code and checked in a
(hopefully) working version. Please try it out and do some performance
tests. I have to admit, that it did not really feel any faster.

opendemo/src/libs/od_filebuf.h 1.3 -> 1.4
opendemo/src/libs/od_filebuf.c 1.3 -> 1.4

fbShrink() is now useless, as fbSkip() alone advances the read pointer (tail)
and makes the ring buffer smaller. I did not implement any resizing to 
conserve memory: if an fbGrow() request is too big, the ring buffer grows
accordingly with mbResize() but if we have nothing more to read from the
buffer, it won't reduce its memory buffer size. All this odRealloc() stuff was
really too much.

Bye, Uwe
