[svn-r155] Changes since 19980114
---------------------- ./html/Datasets.html Removed some archaic comments about data spaces. Fixed example code. ./MANIFEST ./html/H5.format.html ./src/H5O.c ./src/H5Oprivate.h ./src/H5Ocstore.c [DELETED] ./src/H5Oistore.c [DELETED] ./src/H5Olayout.c [NEW] ./src/Makefile.in ./test/istore.c Replaced H5O_CSTORE and H5O_ISTORE messages with a more general H5O_LAYOUT message. ./src/H5D.c ./src/H5Dprivate.h ./src/H5Dpublic.h A little more work on the pipeline. Access to the file data is through the new H5F_arr_read() and H5F_arr_write() which do I/O on hyperslabs of byte arrays and don't depend on data layout. This should simplify the I/O pipeline quite a bit. I also added another argument to H5Dread() and H5Dwrite() to describe the hyerslab of the file array on which I/O is occuring. We discussed this at last week's meeting. ./src/H5Farray.c [NEW] Added functions that sit on top of H5F_block_read() and H5F_istore_read() and implement a common set of functions between all layouts. This means I/O of hyperslabs of byte-arrays in the file to arrays of bytes in memory. When operating on arrays of elements (>1byte) then we just add another dimension. That is, a 10x20 array of int32 becomes a 10x20x4 array of bytes. [This is the area I'll be working on most of next week to implement partial I/O for contiguous data and to improve performance for chunked data.] ./src/H5Fistore.c ./src/H5Fprivate.h Replaced the H5F_istore_t data type with the layout message H5O_layout_t which looks almost the same. Eventually I'd like to rename `istore' to `chunked' everywhere and use `istore' for 1-d storage where the chunks are all different sizes like in the small object heap where each object is a chunk. ./src/H5V.c Changed ISTORE to LAYOUT in one place. ./test/dsets.c Fixed for extra argument to H5Dread() and H5Dwrite().
