Wiki page edited by sgbeal Jul 16, 2009 issue 19 (add client-defined metadata to inodes) reported by sgbeal - To consider: add a client-configurable number of bytes for storing raw client data associated with each inode. The EFS engine would not encode/decode the data in any way - it would only supply access to the bytes. The bytes could be stored as part of the inode metadata block, and need not be represented in the in-memory data structures (it would only exist on the storage). Potential uses: - file access rights, including user/group info. - storing thumbnails - storing comments - or whatever the main problem with this feature is that because the data is client-specific, it won't be useful in conjunction with generic tools like whefs-cp. Another problem is that the client must be good at guessing how much space he'll need for each inode.

Status: Fixed Jul 13, 2009 issue 15 (mmap() support crashes on some platforms) Status changed by sgbeal - Re-opening, as i've seen the crash on a newer Linux x86/64 system (kernel 2.6.18) with a much newer gcc (4.1.2). The system unfortunately has no gdb so i cannot exactly track down the error, but can verify that the difference which causes the crash is the mmap option. In the next version i'll disable the mmap code by default, for the sake of portability.

Jul 02, 2009 issue 16 (Need a way to report the used/remaining space) Labels changed by sgbeal - Labels: Type-Enhancement −Type-Defect Labels: Type-Enhancement −Type-Defect Jul 02, 2009 issue 16 (Need a way to report the used/remaining space) reported by sgbeal - It is currently very tedious to calculate the space used by all inodes, and there is no simple way to do it from client code. We need to add something along the lines of: int whefs_fs_sizes( whefs_fs , whio_size_t used, whio_size_t * capacity, whio_size_t * containerSize ); which would calculate the space and return it to the user via the numeric parameters. That said, the algorithm would be O(N), where N is the number of inodes. The total capacity is a simple calculation based on whefs_fs_options, but the in-use space has to be queried from each inode. Caching that value centrally and updating it on each inode write would be extremely problematic, and would be useless when one considers cross-app concurrency.
