[svn-r25] ./src/H5AC.c
We sort the cache before a complete flush because it might be more efficient to write things back to disk in order of increasing address. If you want the old way then undef the SORT_BY_ADDR constant at the top of H5AC.c I haven't determined which systems and I/O libraries this helps or hurts. (This is currently off because of a bug I need to track down that causes qsort() to run for a really long time). ./src/H5B.c Fixed a couple more bugs. ./src/H5Eprivate.h ./src/H5Eproto.h Added major H5E_DIRECTORY and minor H5E_EXISTS, H5E_COMPLEN. ./src/H5G.c Added directory-aware functions. The heap and B-tree are created when a directory is created instead of when the first symbol is added. This simplifies symbol table entry caching for the directory since the cached value never changes now. ./src/H5Gnode.c ./src/H5Gprivate.h Fine tuned the B-tree K values for symbol tables assuming an average number of symbols is about 100 per directory. The tuning minimizes storage space. Fixed a return value in H5G_node_cmp(). ./src/H5H.c ./src/H5Hprivate.h Moved some macros the the header file. ./src/H5O.c ./src/H5Ocont.c ./src/H5Onull.c ./src/H5Ostab.c Changed the arguments for the decode method for messages. The second argument is the raw message size. Added a class variable for native message size. Added H5O_reset() to free memory used internally by a message. ./src/H5Oname.c NEW ./src/H5Oprivate.h ./src/Makefile The object name message. ./src/hdf5port.h Added defn for HDstrdup()
