---------------------- ./tools/h5ls.c Added a `--address' (`-a') switch which causes h5ls to display file addresses for raw data. For contiguous datasets it's just a nice simple number, but for chunked datasets it's a list of logical dataset coordinates, file addresses, filter masks, and storage sizes. Changed `--dump' switch to `--data'. ./src/H5D.c ./src/H5F.c ./src/H5Fprivate.h Enhanced the indexed-storage B-tree iterator so it can dump raw data addresses (and other info) to the standard error stream. Added H5Ddebug() so h5ls has a way to dump addresses for datasets. I'm not sure what else this API function should do, so I think we should discuss it before we document it. So far, h5ls is the only thing that uses it, and we can easily change that. ./src/H5Tconv.c ./test/dtypes.c Finally had a chance to verify Paul's H5T_conv_s_s (general string to string conversions) bug fixes and incorporate them into H5T_conv_f_f (general floating-point to floating-point conversions) and H5T_conv_i_i (general integer to integer conversons). Thanks Paul. ./src/H5D.c ./src/H5S.c ./src/H5Sprivate.h Added performance timers around data space read and write callbacks. They were already there for the gather/scatter callbacks. The timings for read/write callbacks are displayed along with gather/scatter when data space debugging is turned on. ./bin/iostats Updated to print totals. Added a `--fast' option that doesn't do any output except the totals and is much faster. ./bin/trace Changed __unused__ to UNUSED to match source code. ./config/gnu-flags Updated error message for pgcc. I've sent bug reports to the pgcc people but the new version still has the same bug. ./configure.in ./config/conclude.in ./config/depend.in Fixed dependencies for non-GNU makes when run in a directory other than the hdf5 source tree. Updated GNU `make dep' rules to copy the distributed dependencies for non-GNU makes into the source tree when run in some other directory.
