Good luck doing that cross platform in java :)
Well, I didn't mean mount as in actually mount a file system, just
unzip and maintain an uncompressed directory tree of the portions of
the zip file that are in use in java.io.tmpdir. Right now truezip is
updating the zip file itself for every single operation, and that's
where it's losing all performance. So, it's not _that_ hard ;-).
So you are basically suggesting some kind of cache layer with delayed
write operations?
Yes, indeed. Have the system unpack the parts of the zip that are
actively used and only do an actual write on a FileSystem.close() (or
perhaps on a flush). Without this type of layer, the performance will be
pretty poor.. (as it is with the mockup of the zip filesystem based on
truezip).
Perhaps a generic approach for that might be suitable?
Indeed. I've been meaning to look into this but haven't had time.
