| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

| | | | | | | | | | | | Purpose: __DLL__ is a keyword in some platforms and __DLL__ is also defined as a macro for windows DLL applications. That causes problems. Description: Solution: Use H5_DLL*** to replace __DLL***__ at all header files. Change the macro defination at H5api_adpt.h. Platforms tested: linux2.2.18smp, irix64, solaris 2.7 and windows 2000

| | | | | | | | | | | | | | | | | | | | | | | | Code cleanup. Description: Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros equivalents in the SAF library and adapted them to our library. I added an additional macro which is equivalent to FUNC_ENTER: FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but none of the library or interface initialization code. This is to be used _only_ for static functions and those which explicitly cannot have the library or interface initialization code enabled (like the API termination routines, etc.). This allowed many more of the functions in the library [but not all yet :-(] to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs. It also reduced the size of the library and executables (by cutting out a bunch of code which was never executed), I'll e-mail the exact results when I've finished editing it. Platforms tested: IRIX64 6.5 (modi4)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5.c Fixed more dependency problems in H5_term_library(). There was a bug in the previous version that could cause the wrong EOF marker to be written to the boot block under certain circumstances. Hopefully this fixes it although I don't ready access to a test case (Mark Miller will test it). ./src/H5F.c ./src/H5Fprivate.h Added an H5F_close_all() that is similar to H5F_term_interface() but which doesn't close the interface. Files that don't have open object headers are closed, others are delayed until all object headers close. All files are flushed. ./src/H5ACprivate.h ./src/H5Bprivate.h ./src/H5Dprivate.h ./src/H5Eprivate.h ./src/H5Fprivate.h ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5Gpublic.h ./src/H5HGprivate.h ./src/H5HLprivate.h ./src/H5Iprivate.h ./src/H5MFprivate.h ./src/H5MMprivate.h ./src/H5Oprivate.h ./src/H5Pprivate.h ./src/H5Ppublic.h ./src/H5RAprivate.h ./src/H5Sprivate.h ./src/H5Spublic.h ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h ./src/H5Vprivate.h ./src/H5Zprivate.h ./src/H5private.h ./src/H5public.h Reindented after __DLL__ was added.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./MANIFEST Replaced Compression.html with Filters.html ./doc/html/Filters.html ./src/H5Ocomp.c ./src/H5P.c ./src/H5Ppublic.h ./src/H5Z.c ./src/H5Zprivate.h Added two extra arguments to H5Pget_filter() in order to retrieve the filter name. The name is the name registered for the filter with H5Zregister(), but if the dataset creation property originally came from an existing file then the name is that which is stored in the file. ./tools/h5ls.c The `-v' option now prints the names of the filters. ./src/H5B.c ./src/H5Fistore.c ./src/H5O.c ./src/H5Oefl.c ./src/H5Oprivate.h ./src/H5P.c Plugged a memory leak. ./src/H5MMprivate.h H5MM_malloc(0) and H5MM_calloc(0) actually allocate a single byte in order to be sure that we get a valid pointer. ./src/H5S.c ./src/H5Sselect.c Fixed pointer->integer conversions in error return values in three places.

The `x' was removed from the name to remind us of that: H5MM_xmalloc() -> H5MM_malloc(), etc. H5MM_calloc() takes one argument like H5MM_malloc() instead of two like calloc() because we almost always called it with `1' for one of the arguments anyway. The only difference between the two functions is that H5MM_calloc() returns memory which is initialized to zero. ./src/H5Gent.c ./src/H5Gprivate.h Removed H5G_ent_calloc() since it wasn't used. ./src/H5Fistore.c Fixed a bug found by Albert. Thanks, Albert! This fix combined with the changes to memory allocation prevent the library from failing an assertion if the application uses an unreasonable size for chunks (like Alberts 10000x10000x4). ./src/H5MF.c ./src/H5MFprivate.h Changed H5MF_free() to H5MF_xfree() since calling it with an undefined address is allowed.

Don't try to open a compressed dataset though because the compression message won't be read. ./html/Datatypes.html ./html/H5.api.html ./src/H5.c ./src/H5private.h ./src/H5D.c ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h Added timing support. When compiled with H5T_DEBUG defined the library will print conversion bandwidths when the library closes. The H5Tregister functions take a string as the first argument so the statistics output is meaningful. ./MANIFEST Added new files. ./configure.in ./src/H5config.h.in Check for getrusage(). Check for compress2() in libz.a and the zlib.h header file. Added `z' to the debug list. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c ./src/debug.c Cleaned up some indentation and added support to print istore B-trees. From the debugger, give the B-tree address and the dimensionality from the layout message of the object header. ./src/h5ls.c The oid is printed as w:x:y:z where w and x are the file ID and y and z are the OID within the file. You can give z or y*2^32+z as an argument to the debugger to print the object header for the object. ./src/H5AC.c Cleaned up statistics and made them match those reported by H5T and H5Z. ./src/H5MM.c ./src/H5MMprivate.h ./src/H5Fistore.c Finally got rid of a couple of long-standing const cast warnings.

This reduces the number of warnings in other parts of the code but creates a new warning in this file. ./src/H5O.c Plugged a few memory leaks that happen during error handling. ./src/H5Oname.c ./src/debug.c Added `HD' to the beginning of some posix functions.
