* Fixed bug where read/write intent in file IDs created with H5Freopen

was not being kept the same as the original file. QAK - 2002/05/14

* Fixed bug where selection offsets were not being used when iterating

through point and hyperslab selections with H5Diterate(). QAK - 2002/04/29

variable-length datatypes used for datasets were getting corrupted when

New Features
|
||||
============
|
||||
|
||||
* Added 'closing' parameter to VFL 'flush' callback function and H5FDflush.
|
||||
This allows the library to indicate that the file will be closed
|
||||
immediately following the call to 'flush' and can be used to avoid actions
|
||||
that are duplicated in the VFL 'close' callback function. QAK - 2002/05/20
|
||||
* Added feature to parallel chunk allocation routine to not write fill
|
||||
values to chunks allocated if the user has set the "fill time" to never.
|
||||
This can improve parallel I/O performance for chunked
|
||||
datasets. QAK - 2002/05/17
|
||||
* Changed method for allocating chunked dataset blocks in parallel to only
|
||||
allocate blocks that don't already exist, instead of attempting to create
|
||||
all the blocks all the time. This improves parallel I/O performance for
|
||||
chunked datasets. QAK - 2002/05/17
|
||||
* Allowed the call to MPI_File_sync to be avoided when the file is going to
|
||||
immediately be closed, improving performance. QAK - 2002/05/13
|
||||
* Allow the metadata writes to be shared among all processes, easing the
|
||||
burden on process 0. QAK - 2002/05/10
|
||||
* New functions H5Glink2 and H5Gmove2 were added to allow link and move to
|
||||
be in different locations in the same file. The old functions H5Glink
|
||||
and H5Gmove remain valid. SLU - 2002/04/26

datatype conversion is unneccessary. QAK - 2002/04/02

* Improved performance of single hyperslab I/O when datatype conversion is

unneccessary. QAK - 2002/04/02
|

* New API function H5Dset_extent. Modifies the dimensions of a dataset,

allows change to a lower dimension. The unused space in the file is freed.

"point"). QAK - 2002/02/7

datasets for a few more cases. QAK - 2002/01/31

- Added aditional parameter "dims" to the h5dread/h5dwrite and

h5aread/h5awrite subroutines. This parameter is 1D array of size
|
||||
7 and contains the sizes of the data buffer dimensions.

- F90 subroutines h5dwrite_f, h5dread_f, h5awrite_f and h5aread_f were

overloaded with "dims" argument to be assumed size array of type
|

INTEGER(HSIZE_T). We recommend to use the subroutines with the new type.

Module subroutines that accept "dims" as INTEGER array of size 7 will be
|
||||
depricated in 1.6 release.
