If the fill value writting time is set to - H5D_FILL_TIME_NEVER, the library prohibits user to create VL type dataset. - The library free all the heap objects storing VL type if there is nested - VL type(a VL type contains another VL type).

QAK - 2002/01/23 - * Fixed bug where variable-length datatypes for attributes was not working - correctly. - * Retired the DPSS virtual file driver (--with-gridstorage configure - option). - * Corrected behavior of H5Tinsert to not allow compound datatype fields to - be inserted past the end of the datatype. - * Fixed the internal macros used to encode & decode file metadata, to avoid - an unaligned access warning on IA64 machines. - * Fixed an off-by-one error in H5Sselect_valid when hyperslab selections - which would allow hyperslab selections which overlapped the edge of the - selection by one element as valid. - * Fixed a bug in internal B-tree code where a B-tree was not being copied - correctly. - * Fixed a bug in the 'big' test where quota limits weren't being detected - properly if they caused close() to fail. - * Fixed a bug where 'or'ing a hyperslab with a 'none' selection would - fail. Now adds that hyperslab as the first hyperlab in the selection. - * Fixed a bug where appending a point selection to the current selection - would not actually append the point when there were no points defined - currently. - * Fixed a bug where reading or writing chunked data which needed datatype - conversion could result in data values getting corrupted. - * Fixed a bug where reading an entire dataset wasn't being handled - optimally when the dataset had unlimited dimensions. Dataset is read - in a single low-level I/O now, instead of being broken into separate - pieces internally. - * Fixed a bug when reading chunked datasets where the edge of the dataset - would be incorrectly detected and generate an assertion failure. - * Added new parallel hdf5 tests in t_mpi. The new test checks if the - filesystem or the MPI-IO can really handle greater than 2GB files. - If it fails, it prints information message only without failing the - test. - * Fixed a bug in H5FD_mpio_flush() that might result in negative file seek - if both MPIO and Split-file drivers are used together. - * Fixed H5FDmpio.h to be C++ friendly by making Parallel HDF5 API's to be - external to C++. - * Fixed a bug of H5pubconf.h causing repeated definitions if it is included - more than once. hdf5.h now includes H5public.h which includes - H5pubconf.h. Applications should #include hdf5.h which handles multiple - inclusion correctly. - * Tweaked a few API functions to use 'size_t' instead of 'unsigned' or - 'hsize_t', which may cause errors in some cases. - * Changed behavior of H5Tget_member_type to correctly emulate HDF5 v1.2.x - when --enable-hdf5v1_2 configure flag is enabled. - * Removed limitation that the data transfer buffer size needed to be - set for datasets whose dimensions were too large for the 'all' selection - code to handle. Any size dimensioned datasets should be handled - correctly now. - * The allocation by alignment (H5Pset_alignment) feature code somehow - got dropped in some 1.3.x version. Re-implemented it with "new and - improved" algorithm. It keeps track of "wasted" file-fragment in - the free-list too. - * IMPORTANT: Fixed file metadata corruption bug which could cause metadata - data loss in certain situations. - * Fixed build on Linux systems with --enable-static-exec flag. It now - works correctly. - * Fixed bug with non-zero userblock sizes causing raw data to not write - correctly. - * The RCSID string in H5public.h was causing the C++ compiling problem - because when it was included multiple times, C++ did not like multiple - definitions of the same static variable. All occurance of RCSID - definition are removed since we have not used it consistently before. - * Fixed bug where non-aligned hyperslab I/O on chunked datasets was - causing errors during I/O - * Fixed bug with contiguous hyperslabs not being detected, causing - slower I/O than necessary. - - -Configuration -------------- - - * Included the both the examples of fortran and c++ "make check-install" - testing. This tests the correctness of the h5fc command. AKC - 2003/04/22 - * When using gcc 3.x, we use -std=c99 instead of -ansi for compiling. - QAK - 2003/04/11 - * IA64 platform has its own configure setting and use Intel Compilers as - the default compilers (were gcc and pgf90 before.) This also eliminated - the segmentation fault in the fortran test. The missing reference of - "exit" is fixed too. AKC - 2003/04/02 - * Added "--with-dmalloc" flag, to easily enable support for the 'dmalloc' - debugging malloc implementation. -QAK, 2002/07/15 - * Can use just enable-threadsafe if the C compiler has builtin pthreads - support. - * Require HDF (a.k.a. hdf4) software that consists of a newer version - of zlib library which consists of the compress2() function. Versions - HDF version 4.1r3 and newer meets this requirement. The compress2 - uses a newer compression algorithm used by the HDF5 library. Also, - 4.1r3 has an hdp tool that can handle "loops" in Vgroups. - * Added --enable-linux-lfs flag to allow more control over whether to enable - or disable large file support on Linux. - * Basic port to Compaq (nee DEC) Alpha OSF 5. - * Changed the default value of $NPROCS from 2 to 3 since 3 processes - have a much bigger chance catching parallel errors than just 2. - * Fixed minor problem with configuration when users specified /usr/include - and /usr/lib for the --with-* options that some compilers can't handle. - BW - 2003/01/23 - - -Tools ------ - - * Added a -force option to h5redeploy. AKC - 2003/03/04 - * The VL string bug(data and datatype cannot be shown) in h5dump is fixed. - -SLU - 2002/11/18 - * Fixed segfault if h5dump was invoked with some options but no file (e.g., - h5dump -H). -AKC, 2002/10/15 - * Fixed limitation in h5dumper with object names which reached over 1024 - characters in length. We can now handle arbitrarily larger sizes for - object names.
