* [svn-r4965] Purpose:Quincey Koziol2002-02-141-4/+9
| | | | | | | | | | | | | Bug Fix Description: If a non-zero fill-value is used for a chunked dataset, any non-existent chunked read with an "all" selection (or a contiguous hyperslab selection) will return zero for those instead of the user's fill-value. Solution: Fixed I/O code to pass down fill-value to "optimized" I/O routines, so it will be available to fill the user's buffer with. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4921] Pedro Vicente Nunes2002-02-071-0/+137
| | | | | | | | | | | | | Description: modified the below files to inlude a new public function H5Dset_extend, similar to H5Dextend, but it can lower the dimension this function requires 2 more new private functions: H5D_set_extend H5S_set_extend Platforms tested:
* [svn-r4903] Purpose:Quincey Koziol2002-02-061-166/+120
| | | | | | | | Code cleanup Description: Clean up H5D_read and H5D_write routines, adding comments, etc. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4706] Purpose:Quincey Koziol2001-12-121-14/+10
| | | | | | | | | | | | Code cleanup Description: Tweaked internal error handling macros to reduce the size of the library's object code by about 10-20%. Also cleaned up some compiler warnings... Platforms tested: FreeBSD 4.4 (sleipnir)
* [svn-r4696] Raymond Lu2001-12-111-1/+0
| | | | | | | | | | | | | | | | | Purpose: Modify H5Fclose behavior Description: The HDF5 actual file close behaves in several ways in terms of if there are still objects(dataset, group, datatype) opened in file. Solution: Added a new file access property, file close degree. It has four values, H5F_CLOSE_DEFAULT H5F_CLOSE_WEAK H5F_CLOSE_SEMI H5F_CLOSE_STRONG The way a file is closed is decided by these values. Platforms tested: IRIX64 6.5, SunOS 5.6, FreeBSD 4.4
* [svn-r4680] Purpose:Quincey Koziol2001-12-061-0/+4
| | | | | | | | | | | | | Code cleanup Description: Property that H5P(g|s)et_hyper_cache uses is no longer in use inside the library. Solution: Removed H5P(g|s)et_hyper_cache API functions, except when backward compatibility is turned on. When backward compatibility is turned on, the property is defined by the library, but unused internally. Platforms tested: FreeBSD 4.4 (sleipnir)
* [svn-r4643] Purpose:Quincey Koziol2001-11-271-10/+13
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Windows is generating hundreds of warnings from some of the practices in the library. Mostly, they are because size_t is 32-bit and hsize_t is 64-bit on Windows and we were carelessly casting the larger values down to the smaller ones without checking for overflow. Also, some other small code cleanups,etc. Solution: Re-worked some algorithms to eliminate the casts and also added more overflow checking for assignments and function parameters which needed casts. Kent did most of the work, I just went over his changes and fit them into the the library code a bit better. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4622] Purpose:Quincey Koziol2001-11-201-538/+447
| | | | | | | | | | | Code cleanup Description: Be more careful when starting up and shutting down APIs, only initialize variables which are actually shut down already. Get rid of IDs from internal function calls Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4586] Purpose:Quincey Koziol2001-11-021-28/+35
| | | | | | | | | | | | | | Code speedups, etc. Description: Bring in new algorithms and data structures for dealing with hyperslabs. This speeds up the hyperslab I/O for non-regular hyperslabs by a huge amount. Currently, the new API functions are ifdef'ed out, pending discussion and consensus approval. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4584] Raymond Lu2001-11-021-7/+7
| | | | | | | | | Purpose: Switch from old property list to new generic property list. Description: Mainly changed H5Pcreat, H5Pclose, H5Pcopy. Platforms tested: IRIX64 6.5, FreeBSD, SunOS 5.7.
* [svn-r4543] Raymond Lu2001-10-151-9/+9
| | | | | | | Purpose: Changed the file creation property list to the new generic property list. Platform tested: IRIX64, SunOS5.7, FreeBSD
* [svn-r4520] Purpose:Quincey Koziol2001-10-041-1/+1
| | | | | | | | | Bug fix Description: Remove 'const' modifier in prototype for H5D_new, the dcpl_id parameter needs to be non-const. Platforms tested: Eyeballed (reported on gondolin)
* [svn-r4518] Purpose:Quincey Koziol2001-10-031-11/+21
| | | | | | | | Code cleanup Description: Clean up some small compiler warnings. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4517] Raymond Lu2001-10-031-241/+571
| | | | | | | | Purpose: Changed to the new generic property list for dataset creation property list. Platforms tested: Arabica, modi4 and Hawkwind
* [svn-r4508] Purpose:Quincey Koziol2001-10-021-4/+19
| | | | | | | | | | | | | Document bug fix. Description: When reading or writing to chunked datasets and the data needed datatype conversion, and the amount of data was more than one conversion buffer, data in the conversion buffer was getting corrupted. Solution: Corrected error in advancing buffer pointer where it was being advanced by the number of elements instead of the number of bytes. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4482] Purpose:Quincey Koziol2001-09-261-6/+6
| | | | | | | | | | | | | | | | | | | | | | Kludge Description: Since we're only about halfway through converting the internal use of property lists from the "old way" to the generic property lists, we turned off snapshots to avoid exposing lots of API changes to users, until the APIs settled down. Getting the snapshots rolling again seems to have become a priority, so some changes are going to have to be made now that were going to be postponed until we were completely finished with the conversion. This requires that the old API functions be able to deal with both the old and new property lists smoothly. Solution: Kludge together the property list code so that they can transparently handle dealing with both the old and new property lists Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-11/+11
| | | | | | | | | | | | | | | | | | | | | | Code cleanup (sorta) Description: When the first versions of the HDF5 library were designed, I remembered vividly the difficulties of porting code from a 32-bit platform to a 16-bit platform and asked that people use intn & uintn instead of int & unsigned int, respectively. However, in hindsight, this was overkill and unnecessary since we weren't going to be porting the HDF5 library to 16-bit architectures. Currently, the extra uintn & intn typedefs are causing problems for users who'd like to include both the HDF5 and HDF4 header files in one source module (like Kent's h4toh5 library). Solution: Changed the uintn & intn's to unsigned and int's respectively. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4329] Purpose:Quincey Koziol2001-08-121-3/+3
| | | | | | | | | | | | | | Bug Fix Description: The datatype conversion buffer size was only halfway converted from hsize_t to size_t and was causing problems. Also, the H5P_peek_<foo> routines have a bunch of identical code. Solution: Finished converting the datatype conversion buffer size to size_t and cleaned up the implementation of the H5P_peek_<foo> routines to call a common routine instead of reimplementing a bunch of code. Platforms tested: Solaris 2.7 (arabica)
* [svn-r4324] Purpose:Quincey Koziol2001-08-101-119/+286
| | | | | | | | | | | | | | | | | | | | | | | | New Features! Description: Start migrating the internal use of property lists in the library from the older implementation to the new generic property lists. Currently, only the dataset transfer property lists are migrated to the new architecture, all the rest of the property list types are still using the older architecture. Also, the backward compatibility features are not implemented yet, so applications which use dataset transfer properties may need to make the following changes: H5Pcreate(H5P_DATASET_XFER) -> H5Pcreate_list(H5P_DATASET_XFER_NEW) and H5Pclose(<a dataset transfer property list>) -> H5Pclose_list(id) This still may have some bugs in it, especially with Fortran, but I should be wrapping up those later today. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4181] Purpose:Quincey Koziol2001-07-101-12/+16
| | | | | | | | | Bug Fix, Code Cleanup, Code Optimization, etc. Description: Fold in the hyperslab speedups, clean up compile warnings and change a few things from using 'unsigned' or 'hsize_t' to use 'size_t' instead. Platforms tested: FreeBSD 4.3 (hawkwind), Solaris 2.7 (arabica), Irix64 6.5 (modi4)
* [svn-r4038] Purpose:Quincey Koziol2001-06-211-4/+4
| | | | | | | | | | | | | Code clean/bug fix Description: H5FL (free-list manager) code currently is taking an hsize_t as the size of a memory block to allocate. On many machines, the size of an hsize_t is greater than the size of a size_t, potentially leading to incorrect memory allocations in rare circumstances. Solution: Changed hsize_t parameters and variables to size_t. Platforms tested: FreeBSD 4.3 (hawkwind)
* [svn-r4002] Purpose:Quincey Koziol2001-06-141-18/+18
| | | | | | | | | | | | | Bug fix/code improvement. Description: 'all' selections were (ab)using the array reading code and required that the internal data transfer buffer size be big enough to hold the an entire slab of the data, which was confusing and limiting for users. Solution: Changed 'all' selections to use sequence reading code instead of array reading code. Platforms tested: FreeBSD 4.3 (hawkwind)
* [svn-r3781] Purpose:Bill Wendling2001-04-051-15/+15
| | | | | | | | | | | | | | | | | | Update Description: Changed #include <hdf_file.h> construct to #include "hdf_file.h" so that the GNU compiler can more easily pick up the dependencies which it places in the .depend and Dependencies files. Also regenerated the Dependencies to go along with this. Platforms tested: Linux
* [svn-r3677] Purpose:Albert Cheng2001-03-201-4/+0
| | | | | | | | | | | | | Bug fix (sort of) Description: The RCSID string in H5public.h was causing the C++ code problem as it was included multiple times and C++ did not like multiple definitions of the same static variable. Solution: Since we don't really make use of the RCSID strings as we have not installed it in all source files, we decided to remove it. Platforms tested: eirene (linux), modi4 (IRIX64-64) both serial and parallel modes.
* [svn-r3302] Purpose:Quincey Koziol2001-01-181-1/+9
| | | | | | | | | | | | | Bug fix Description: Certain combinations of hyperslabs, especially those that have to be strip-mined during I/O were causing data to be incorrectly transferred. Solution: Changed the code in H5S_get_hyper_regions to be more careful about the regions of the current dimension that are valid. Sometimes, regions which had already been iterated through were being re-processed. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3280] Purpose:Quincey Koziol2001-01-121-0/+17
| | | | | | | | | | | | Bug fix Description: Datasets were allowed to be created with chunks larger than the maximum dimension for each dimension. Solution: Compare chunk sizes against maximum dimensions and reject dataset creations which have chunks too large for the dimensions in the dataspace. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3252] Purpose:Quincey Koziol2001-01-091-273/+267
| | | | | | | | | | | | | 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-r3236] Purpose:Quincey Koziol2001-01-041-5/+4
| | | | | | | | Clean up code. Description: Cleaned up various compiler warnings. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3228] Purpose:Quincey Koziol2001-01-031-19/+28
| | | | | | | | | | | | | | | | | | | | Bug fixes Description: Fix two bugs: - Datasets with vlen datatype which were created but not written to were not being read back in correctly from the file. - If an existing space conversion path was found for a conversion, it was possible that the optimized read/write routines would be used inappropriately. Solution: Patched vlen datatype conversion code to correctly handle zero-length sequences. Added a check to the space conversion code to make certain that the optimized conversion routines are still appropriate when an existing path is found. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3110] Purpose:Quincey Koziol2000-12-111-22/+28
| | | | | | | | | | | Bug Fix Description: Compound datatypes weren't reading background data properly when used with array or vlen fields. Solution: Changed to always read background information from file in those situations. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3008] Purpose:Quincey Koziol2000-11-281-1/+1
| | | | | | | | | | | | | | Code cleanup Description: Several places in the code were using -2 as a default value for various features. However, when a default value is returned from a function that is supposed to return negative on failure, it was causing confusion and extra work for users to check for the special value. Solution: Replaced hard-coded -2 values in the code with symbolic names, then changed symbolic names to 0 instead of -2. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3005] Purpose:Quincey Koziol2000-11-271-6/+6
| | | | | | | | Backward compatibility code Description: Add in code to allow the library to emulate the v1.2 API and behavior. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3003] Purpose:Albert Cheng2000-11-271-2/+19
| | | | | | | | | | | | | | | | | | Bug fix Description: The optimized MPI-IO calls, H5S_mpio_spaces_write/H5S_mpio_spaces_read, are changed for collective data transfer only since they call H5FD_mpio_setup to do setup to eveually call MPI_File_set_view in H5FD_mpio_read or H5FD_mpio_write. MPI_File_set_view is a collective call. Letting independent data transfer use this route would result in hanging. Solution: For now, the checking is being done in H5D_write and H5D_read before H5S_mpio_spaces_write/H5S_mpio_spaces_read is called because the checking code in H5S_mpio_spaces_xfer, though with the right idea, is not correct yet. Platforms tested: IRIX64-64 parallel.
* [svn-r2990] Purpose:Albert Cheng2000-11-211-34/+136
| | | | | | | | | | | | | | | | | | | | | Bug fix (feature, kind of) Description: The library used to hang if a collective dataset read/write request does not have the same number of eventual MPIO request. Part of the reason is that H5FD_read/H5FD_write immediately returns succeess if it sees the request size is 0. This caused problem since other processes with I/O to do would be hanging by waiting for the early returned process(es). Solution: H5FD.c: disable the early return code in parallel mode. Make it go on even with "nothing" to transfer. H5D.c: the optimized MPIO xfer routines can handle collect calls correctly when the condition is right (e.g., no conversion). When the COLLECTIVE request cannot be handled correctly without the risk of hanging, the COLLECTIVE is changed to INDEPENDENT calls for the eventual MPIO calls. Platforms tested: IRIX64 parallel (-64, n32), IRIX64 -64 sequential, Linux sequential.
* [svn-r2866] Purpose:Quincey Koziol2000-11-111-2/+2
| | | | | | | | Code cleanup Description: Found more "Have_foo" usage and converted them to "H5_HAVE_foo" Platforms tested: FreeBSD 4.1.1 (hawkwind)
* [svn-r2752] Purpose:Albert Cheng2000-10-301-1/+1
| | | | | | | | | | | Bug fix Description: There is typo in the H5D_write function which reported the optimized write failure as a H5E_READERROR. Solution: Replaced it with the correct H5E_WRITEERROR code. Platforms tested: modi4 parallel (compiled H5D.o only).
* [svn-r2652] Purpose:Quincey Koziol2000-10-101-9/+35
| | | | | | | | | | | | | | | Maintainance & performance enhancements Description: Re-arranged header files to protect private symbols better. Changed optimized regular hyperslab I/O to compute the offsets more efficiently from previous method of using matrix operations. Added sequential I/O operations at a more abstract level (at the same level as H5F_arr_read/write), to support the optimized hyperslab I/O. Platforms tested: Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)

* [svn-r2444] Checkpoint the Generic Property implementation. It's not active ↵Quincey Koziol2000-07-251-0/+27
| | | | | | yet, but it's close. This shouldn't interfere with other development work. (I think.. :-)
* [svn-r2318] Rearranged metadata caching to put caching information in the ↵Quincey Koziol2000-06-011-1/+0
| | | | | | | | objects being cached instead of in separate structures. This reduces the amount of memory the hash table uses by about half. This is the initial step along the path of speeding up the metadata caching.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ** src/H5Tconv.c ** src/H5Tpkg.h ** src/H5Tpublic.h The H5T_conv_struct_opt() function had a design flaw -- it didn't keep information about the stride to use to step through the temporary/background-value buffer and thus nested invocations would clobber each other's temp buffers. 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
* [svn-r2151] Modified H5_term_library to not reported errors when ↵Quincey Koziol2000-04-151-3/+3
| | | | | | | | H5Eset_auto(NULL,NULL) has turned off error reporting in the library. Also, changed the way property lists are managed and closed so that they can be automatically closed when the library terminates.
* [svn-r2109] Re-wrote a good chunk of the hyperslab code to work correctly in ↵Quincey Koziol2000-04-111-5/+4
| | | | | | | several situations which weren't tested before. Things should be both faster and easier to understand in this code now.
* [svn-r2073] Added free-list code to the library and took out the older ↵Quincey Koziol2000-04-041-48/+57
| | | | | | | "temporary buffer" code, since the functionality was superceded. See the followup document for details on the free-list code.
* [svn-r2057] Purpose:Albert Cheng2000-03-241-9/+9
| | | | | | | | | | | | | | Bug fix for parallel mode. Description: H5FD_mpio_tas_allsame was called for all cases, even when MPIO is not used for access. That corrupted the internal file handle structure. Solution: Define a macro, IS_H5FD_MPIO(f), for testing if f is opened with MPIO access. Will call H5FD_mpio_tas_allsame only if this condition is true. Platform tested: O2K, both -64 and -n32 modes.

This fixes a warning on some systems. Checks for the <pdb.h> header file and also for either the PDB or Silo library, and if found prepares to compile the pdb2hdf program. ./config/distdep Relative path names for include files are changed to base names since the makefile contains the logic for searching and since it's likely that building the .distdep files happed from a location other than where they would be used in the file system. ./config/conclude.in Fixed shell errors when `for' loops iterate over nothing for the `uninstall' target. ./src/H5D.c ./src/H5Oefl.c File names for the external files are added to the heap when the dataset is created instead of when the object header is written. This fixes a rare infinite recursion bug. ./src/H5FD.c ./src/H5FDpublic.h Optimization to the free list causes H5FD_alloc() usage to go from >10 seconds to <0.4 second for one example (converting a 30MB equation of state file from PDB to HDF5 format). The optimization is to simply keep track of the largest item in the free list and not search the free list when the largest item is not big enough to satisfy the request. ./src/H5FDcore.c ./src/H5FDcore.h ./test/h5test.c If the `backing_store' property is true then a flush causes the entire contents of memory to be written to the specified file. This is in preparation for the ASCI/red optimizations and is currently tested by the pdb2hdf `--cached' switch. ./src/H5Odtypes.c Wrapped three long lines. ./tools/Makefile.in ./tools/pdb2hdf.c [NEW] A PDB-to-HDF5 translator. It only translates meta data -- the resulting HDF5 points into the PDB file for the raw data.
