* [svn-r11355] Purpose: A new API function and its test.Raymond Lu2005-09-061-0/+1
| | | | | | | | | Description: Put in a new API funciton, H5Tis_hard. It checks whether the conversion function from a native type to another native type is a compiler (hard) conversion. Also checked a test in test/dt_arith.c. Platforms tested: h5committest and fuss.

| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest

| | | | | | | | | | | | | | | | | Feature Description: Added "support" for UTF-8 character encoding. Solution: Wrote tests to check that UTF-8 can be used in a number of places in HDF5 (object names, data, etc.). These tests live in test/tunicode.c. Added a new UTF-8 character encoding for datatypes. Platforms tested: mir, modi4, heping Misc. update:
* [svn-r10456] Purpose: New way to do conversion test from floating-points to ↵Raymond Lu2005-03-261-1/+4
| | | | | | | | | | | | | | | | | | | integers. Description: The 6th step of changing conversion test. This checkin is only for conversion of special values from floating-points to integers. Solution: This test is seperated from regular value conversion. It reuses the same function test_conv_int_float() in test/dtypes.c. The source buffer of floating-point type is filled up with 8 special values, +/-0, +/-infinity, +/-QNaN, +/-SNaN. Also added 3 new conversion exception values H5T_CONV_EXCEPT_PINF, H5T_CONV_EXCEPT_NINF, H5T_CONV_EXCEPT_NAN, for floating-point special values positive infinity, negative infinity, and NaN. These values are for conversion exception callback function defined through H5Pset_type_conv_cb(). (Remember to update the document!) Platforms tested: h5committest

| | | | | | | | | | | Description: Somehow, the hardware conversions between "long double" and other native floating-point types were left out. Solution: Added the hardware conversion functions in H5Tconv.c and test cases in dtypes.c. Platforms tested: h5committest and fuss. Misc. update: updated MANIFEST to replace bin/reconfigure.sh with bin/reconfigure
* [svn-r9984] Purpose: New feature and testRaymond Lu2005-02-101-1/+1

* [svn-r9727] Purpose:Quincey Koziol2004-12-291-17/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes".

* [svn-r8879] Raymond Lu2004-07-141-0/+2
| | | | | | | | | | | | | | Purpose: New feature Description: New API H5Tencode and H5Tdecode. Given object ID, H5Tencode encodes object information into a binary form. H5Tdecode decode an object information in a binary form, reconstructs the object and return a new object ID. Solution: Use object header functions H5O_dtype_decode and H5O_dtype_encode to facilitate them. The encoded binary is exactly like object header information. This is the first step checkin. Will check in H5Sencode and H5Sdecode later. Platforms tested: h5committed and fuss. Misc. update: will update release.txt after 2nd step checkin.

* [svn-r7434] Purpose:Quincey Koziol2003-08-311-1/+1
| | | | | | | | | | | | | | | | | | | | Bug Fix and code cleanup Description: Correct error in H5T_detect_class that was causing nested compound datatypes with to not detect the datatype class of fields correctly, which caused errors with fill-values, variable-length datatypes and chunks later on. Return the rank of the array datatype from H5Tget_array_dims(), like H5Sget_dims(). Lots of cleanups to datatype code, to make the handling of arrays, compound types, variable-length strings and sequences and enumerated types more consistent and robust.

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.

| | | | | | | | | | | | | | Code cleanup Description: Got rid of the "H5T_BKG_TEMP" setting that was used internally to the library, since temporary background buffers are now handled by the individual conversion routines instead of in a global background buffer. No APIs were changed or affected by this. Platforms tested: FreeBSD 4.5 (sleipnir)

| | | | | | | | | | | | | Code cleanup. Description: Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the extra warnings. Including a few show-stoppers for compression on IRIX machines. Solution: Changed lots of variables' types to more sensible and consistent types, more range-checking, more variable typecasts, etc. Platforms tested: FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)
* [svn-r3020] Purpose:Quincey Koziol2000-11-291-0/+1
| | | | | | | | | | Code addition Description: The dumper needs to know when a datatype needs to be reclaimed, so I added a small helper function to detect if a particular datatype is or contains a particular class of datatypes. Platforms tested: Linux 2.2.16-3smp (eirene)

* [svn-r2850] Purpose:Quincey Koziol2000-11-091-9/+1
| | | | | | | | | | | | | Added new function. Description: It's often convenient to query the class of a compound datatype's member to determine if it's an array and the previous way required you to open the member type to query it's class. Solution: Added new H5Tget_member_class function to directly ask for the member type's class. Platforms tested: FreeBSD 4.1.1 (hawkwind)
* [svn-r2843] Purpose:Quincey Koziol2000-11-091-0/+11
| | | | | | | | | | | | | | | New Feature Description: Added array datatype to library. See documentation at: http://hdf.ncsa.uiuc.edu/HDF5/planning/DP/ArrayType.html for complete details on the impact to the library. Solution: Changes to the base library include removing the ability of compound datatype fields to be an array (they can use an array type for the field, to duplicate the functionality) and adding in the new array datatype everywhere appropriate. (I hope :-) Platforms tested: FreeBSD 4.1.1 (hawkwind)

This was fixed by splitting the `stride' argument into `buf_stride' and `bkg_stride' arguments for all the conversion functions. THIS IS AN API CHANGE, but users will get a compiler warning when they pass their conversion function pointer to H5Tregister(). ** src/H5T.c ** src/H5Tprivate.h Added a bkg_stride argument to the H5T_convert() definition in order to fix a bug related to the optimized compound datatype conversion function. ** src/H5T.c ** src/H5A.c ** src/H5D.c ** src/H5Ofill.c ** src/H5P.c Added bkg_stride=0 argument to the H5T_convert() calls. ** test/dtypes.c Added a test for the H5T_conv_struct_opt() bug fixed above. ** src/H5FL.c The H5FL_term() function should return non-zero even when it couldn't free all the free lists do to their being used by some other package. When that other package terminates it will return non-zero, causing H5FL_term() to be called again. This fixes some of the `infinite loop closing library' messages. ** tools/pdb2hdf Uses print_version() instead of doing that itself. ** src/H5Ppublic.h Renamed H5Pget_gc_reference() declaration to make it match the definition. ** src/H5FDlog.c Added API tracing macros. Removed `const' qualifier from a `char*' member of a struct which was allocated on the heap. ** src/H5TB.c Added curly braces to a couple deeply-nested `if' statements to make them clearer and to shut up the increadibly stupid and just plain incorrect gcc warning about ambiguous `else'. ** test/titerate.c Removed incomplete initialization in favor of memset() for one auto variable to stop compiler warnings. ** tools/Depencencies Regenerated to remove references to h5dumputil.c

The H5Pset_fapl_split() function just calls H5Pset_fapl_multi() with arguments which prepare to split the address space into two files: meta and raw data. This is the first version. I plan to allow the open() call to relax a bit which would allow one to open an hdf5 file when only the meta-data file is present. This would allow a very large file to be split and stored on tape and the relatively small meta file to be mirrored on disk to allow limited browsing of the file (any request for raw data would fail). ./src/H5private.h ./src/H5F.c ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c Added the ability for a file driver to store information in the superblock which would be needed if the file were opened again later for reading. The format is driver-defined which allows users to extend it however they like. ./doc/html/H5.format.html Added information about the new driver information block of the superblock. This is where file drivers store information they need in order to reopen the file later. ./src/H5F.c ./src/H5Fprivate.h ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c ./src/H5Fistore.c ./src/H5R.c The file access properties and the file access property list were decoupled, which allows the property list to more cleanly contain properties for various levels of the file and which allows the property list to be modified more cleanly when opening files. ./src/H5.c ./src/H5FDpublic.h Removed H5FD_MEM_META and H5FD_MEM_GROUP since they're never used. ./src/H5D.c Changed the way we detect the MPIO driver in all these special cases. ./src/H5F.c ./src/H5Rpublic.h ./test/tfile.c The default file sizeof(offset) was changed to be a function of haddr_t instead of hsize_t. THE H5RPUBLIC.H DEFINITIONS WILL HAVE PROBLEMS IF THE USER CREATES A FILE WITH NON-DEFAULT OFFSET AND SIZE SIZES! ./src/H5F.c Fixed an uninitialized memory access bug in file closing related to the VFL. ./src/H5T.c ./src/H5Tpublic.h Added an H5T_NATIVE_HADDR predefined datatype which corresponds to the `haddr_t' type. ./test/Makefile.in Reformatted long lines. ./test/big.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Removed the H5F_ACC_DEBUG flag from file creation/open calls. ./test/big.c Plugged a memory leak. ./test/h5test.c Added support for the `multi' driver.

This feature was necessary to implement the compound datatype conversion optimizations and it causes a minor change to the API (application-defined type conversion functions take an extra size_t stride argument). ./src/H5Tconv.c An additional compound data type conversion function was added which is applied unless the destination type is larger than the source type. I'm measuring significant performance increases for certain operations: Test Name Struct-Conv Noop-Conv New(Old) MB/s New(Old) MB/s ---------- ------------- ------------- Reordering 2.062(0.3936) 54087(0.9047) Subsetting 2.901(0.6581) 40192(1.1100) Shrinking 1.976(0.3925) 33628(1.1500) ---------- ------------- ------------- ./test/dtypes.c Added various compound datatype conversion tests. Fixed return values from functions. ./src/H5T.c Conversion timers are updated only if H5T debugging is turned on a runtime (in addition to compile time). This allows the data type layer to be compiled with debugging support without having to pay a big runtime penalty if the debugging isn't actually used. ./src/H5A.c ./src/H5D.c ./src/H5Ofill.c ./src/H5P.c ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h Added the stride argument to the H5T_convert() calls. The stride is always zero, which means that the source and destination data values are packed. ./configure.in ./configure [REGENERATED] If API tracing is turned off then libhdf5.settings will say `no' instead of nothing. ./test/flush1.c ./test/flush2.c Added better error messages in a couple places.

Besides, the fact that something is a datatype is obvious because it starts with H5T_NATIVE_. ./tools/h5ls.c Added the new C9x data types. H5ls prints one of these types only if it doesn't match one of the builtin C types. Prints the OID for shared data types. Fixed a formatting bug with symbolic links which was introduced a few changes ago. The commandline has been changed so that objects from multiple files can be listed with a single command. Instead of specifying a file name and an optional list of objects, each thing to print is a file name and object concatenated. H5ls figures out how to devide the name into a file name and object name even when the file name part doesn't correspond to an actual Unix file. Old syntax: h5ls [OPTIONS] FILE [OBJECTS] New syntax: h5ls [OPTIONS] FILE[/OBJECT] [FILE[/OBJECT]]... Example ({X,Y} is expanded by the shell) Old command: h5ls -d ../test/x.data dir1 dir2 New command: h5ls -d ../test/x.data/{dir1,dir2} The filename is printed as part of the object name when full names are requested (--full or --recursive). If people really don't like this they can undefine a constant at the top of h5ls. Errors from the hdf5 library are turned off. Commandline switches of the form `--width 80' are accepted in addition to `--width=80'. This is more symmetric with single-letter switches that take two forms: `-w 80' and `-w80'. ./src/H5D.c Added tracing instrumentation for H5Dvlen_reclaim(). ./src/H5private.h Added casts to int for the isalpha() et al macros to shut up solaris warnings about char subscripts.

| | | | | | | | | | | | | | | | | | | | ---------------------- ./configure.in ./configure [REGENERATED] ./src/H5T.c ./src/H5Tpkg.h ./src/H5Tpublic.h ./src/H5config.h.in [REGENERATED] ./src/H5detect.c ./src/H5private.h Added checks for the C9x integer types like int32_t, int_least32_t, and int_fast32_t and the unsigned versions. HDF5 defines H5T_NATIVE_* versions (all caps) to be the same as the type provided by the C library, otherwise it defines them as integers exactly the specified size. Hardware type conversion functions are used when the types match some C-language type (like `int').

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- Remove changes from CVS ./bin/release Added a `--nocheck' switch which causes the script to not check the contents of the MANIFEST file against CVS. This is sometimes useful when you need to make a quick snapshot but the MANIFEST file is not quite up to date. ./src/H5D.c Removed warnings for unused variables ./src/H5Fprivate.h Removed the WIN32 definition for `uint' and changed the data type for `eof_written' from `uint' to `uintn'. Shouldn't this really be `hbool_t'? ./src/H5Odtype.c ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tpublic.h ./test/dtypes.c ./doc/html/H5.format.html Added support for bitfields and opaque data types.

We were storing dependencies for *.o files instead of *.lo files after shared libraries were added. ./config/gnu-flags ./config/linux-gnulibc1 Moved `-march=pentiumpro -mcpu=pentiumpro -malign-double' from the linux file to this file and caused it to depend on the CPU name. This fixes one of Elena's bugs. ./src/H5B.c ./src/H5Bprivate.h ./src/H5D.c ./src/H5Dprivate.h ./src/H5Dpublic.h ./src/H5F.c ./src/H5Farray.c ./src/H5Fistore.c ./src/H5Fmpio.c ./src/H5Fprivate.h ./src/H5Fpublic.h ./src/H5Gnode.c ./src/H5P.c ./src/H5RA.c ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Smpio.c ./src/H5Spoint.c ./src/H5Sprivate.h ./src/H5Tpublic.h ./test/istore.c Added an H5Dget_storage_size() function that reports the amount of storage allocated for raw data in a dataset. Changed H5D_xfer_* to H5F_xfer_* because these properties are more general than datasets. This also allows some of the lower-level I/O functions to get this information easier. ./src/H5S.c ./src/H5Sall.c Added two new functions H5S_all_read() and H5S_all_write() which are optimizations that copy data directly between file and memory without having to go through the scatter gather step. This knocks quite a bit of time off the I/O and reading/writing entire datasets is a fairly common operation. ./tools/h5ls.c Reports the logical size of data, the allocated size of data, and the percent utilization. ./MANIFEST Removed old pablo files, added new files. Snapshots should now start to work again. ./src/H5D.c ./src/H5Fmpio.c Removed two warnings signed vs. unsigned comparisons and check for overflow.
