[svn-r451] Completely tore out existing dataspace API and replaced with code to match API defined in the html/Dataspaces.html document. This code does not include support for strides, merging selections, or permutations of coordinates yet, but it's a drop-in replacement for the existing API with the same features.

[svn-r712] Added temporary buffer support to several places in the library which were calling malloc too often. Also, added caching of hyperslab blocks, which improves performance _significantly_ for hyperslab I/O.

It's a one line change. Changed the way the library is closed so we have more control over the order the interfaces are shut down. Instead of registering an atexit() function for every interface in some haphazard order we just register one: H5_term_library() which then calls the H5*_term_interface() functions in a well-defined order. If the library is closed and then reopened repeatedly by calling H5close() and H5open() in a loop we only add one copy of the library termination functions with atexit(). Termination is a two-step process in order to help detect programming errors that would cause an infinite loop caused by the termination of one interface waking up some other previously terminated interface. The first step terminates the interface and *marks it as unusable*. After all interfaces are terminated then we mark them all as usable again. The FUNC_ENTER() macro has been modified to return failure or to dump core (depending on whether NDEBUG is defined) if we try to call an interface while it's shutting down. ./src/H5.c The H5dont_atexit() function returns failure if it's called more than once or if it's called too late. However, the error stack is not automatically printed on failure because the library might not be initialized yet ./test/chunk.c ./test/flush1.c ./test/flush2.c ./test/iopipe.c ./test/overhead.c ./test/ragged.c Changed the extra cast for Win32 so we do floating point division again -- it was just confusion about precedence and associativity of casting and the C coercion rules. Removed extra carriage returns inserted by broken operating system. ./src/H5Ffamily.c Fixed an bug where H5F_fam_write() lowered the EOF marker for one of the family members causing H5F_fam_read() to read zeros. ./test/h5test.h [NEW] ./test/h5test.c [NEW] ./test/Makefile.in ./test/bittests.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Support library for test files. This isn't done yet but Katie's contractions are ~10 minutes apart so I figured I better back this stuff up just in case I'm not here next week... Eventually all test files will understand HDF5_DRIVER to name the low level file driver and parameters so we can easily test various drivers. They will also understand HDF5_PREFIX to prepend to the beginning of file names which is necessary for testing ROMIO with various drivers. Also, the cleanup function will know how to use the file name prefix and will understand different file driver naming schemes like file families. I'm not sure they'll understand the `gsf:' type prefixes yet. Note, the external test is completely commented out because I'm in the middle of modifying it. It will still compile and run but it doesn't test anything at the moment.

The test is not actually part of `make test' because we still have some memory problems. ./src/H5E.c ./src/H5Epublic.h Added H5E_RAGGED as a major error number. ./bin/release Checks the MANIFEST file against `svf ls' on systems that have it. ./bin/trace Fixed a bug that caused arguments of type `void *x[]' to not be handled. ./src/H5.c Removed unused variables and changed a couple types to fix compiler warnings. Added tracing support for ragged array object ID's and arrays of pointers. ./src/H5D.c H5Dcreate() will complain if either of the property lists are invalid (instead of using the default). ./src/H5D.c ./src/H5Dprivate.h Split H5Dget_space() into an API and internal function so it can be called from the new ragged array layer. ./src/H5Fistore.c Fixed warnings about unsigned vs. signed comparisons. ./src/H5Flow.c Fixed a warning about a variable being shadowed in the MPI-IO stuff. ./src/H5Iprivate.h ./src/H5Ipublic.h Added the H5_RAGGED atom group. ./src/H5Shyper.c Fixed some freeing-free-memory errors that resulted when certain arrays were freed but the pointers were left in the data structures. I simply set the pointers to null after they were freed. ./src/H5Sprivate.h ./src/H5Sselect.c Split the H5Sselect_hyperslab() function into an API and a private function so it could be called from the ragged array layer. Added H5S_SEL_ERROR and H5S_SEL_N to the switch statements to get rid or compiler warnings. ./src/H5Tconv.c Removed a misleading comment. ./test/bittests.c Fixed a warning about a printf(). ./test/cmpd_dset.c Fixed warnings about unused variables because of test #11 being commented out. ./bin/trace Shortened the right margin for the output to allow room for the `);' at the end of the TRACE() macros.

DESCRIPTION
Combines a hyperslab selection with the current selection for a dataspace.
If the current selection is not a hyperslab, it is freed and the hyperslab
parameters passed in are combined with the H5S_SEL_ALL hyperslab (ie. a
selection composing the entire current extent). Currently, only the
H5S_SELECT_SET & H5S_SELECT_OR operations are supported. If STRIDE or
BLOCK is NULL, they are assumed to be set to all '1'.

1998-07-10 12:54:19 -05:00
DESCRIPTION
This function selects array elements to be included in the selection for
the dataspace. The COORD array is a 2-D array of size <dataspace rank>
by NUM_ELEM (ie. a list of coordinates in the dataspace). The order of
the element coordinates in the COORD array specifies the order that the
array elements are iterated through when I/O is performed. Duplicate
coordinates are not checked for. The selection operator, OP, determines
how the new selection is to be combined with the existing selection for
the dataspace. Currently, only H5S_SELECT_SET is supported, which replaces
the existing selection with the one defined in this call. When operators
other than H5S_SELECT_SET are used to combine a new selection with an
existing selection, the selection ordering is reset to 'C' array ordering.

NAME
H5Sselect_elements
PURPOSE
Specify a series of elements in the dataspace to select
USAGE
herr_t H5Sselect_elements(dsid, op, num_elem, coord)
hid_t dsid; IN: Dataspace ID of selection to modify
H5S_seloper_t op; IN: Operation to perform on current selection
size_t num_elem; IN: Number of elements in COORD array.
const hssize_t **coord; IN: The location of each element selected
RETURNS
Non-negative on success/Negative on failure
DESCRIPTION
This function selects array elements to be included in the selection for
the dataspace. The COORD array is a 2-D array of size <dataspace rank>
by NUM_ELEM (ie. a list of coordinates in the dataspace). The order of
the element coordinates in the COORD array specifies the order that the
array elements are iterated through when I/O is performed. Duplicate
coordinates are not checked for. The selection operator, OP, determines
how the new selection is to be combined with the existing selection for
the dataspace. Currently, only H5S_SELECT_SET is supported, which replaces
the existing selection with the one defined in this call. When operators
other than H5S_SELECT_SET are used to combine a new selection with an
existing selection, the selection ordering is reset to 'C' array ordering.

Added a test to make sure that reading a file that has a dataset with a space with too large a rank fails. Actually, this one is a little weird: the code that reads the data space message assumes the space is scalar if the message cannot be read. Fortunately the layout message fails also, preventing the dataset from being opened. However, since the data type message is still visible h5ls will report that the object is a named data type. ./test/space_overflow.c [NEW] This is the little program that makes the th5s.h5 file. ./src/H5A.c ./src/H5R.c ./src/H5Sselect.c Updated trace info. ./src/H5Olayout.c ./src/H5Osdspace.c Added code to fail if the dimensionality is too large when decoding a layout or simple data space message. ./src/H5Oprivate.h Redefined H5O_LAYOUT_NDIMS in terms of H5S_MAX_RANK. ./src/H5P.c ./src/H5S.c Check for ndims>H5S_MAX_RANK in API function calls, added assert to internal functions. ./src/H5V.c Changed a `<' to an `<=' in an assert. ./test/flush2.c Includes stdlib.h for getenv(). ./tools/h5tools.c Able to handle up to H5S_MAX_RANK dimensions during output.

Not fully implemented yet. The test is not actually part of `make test' because we still have some memory problems. ./src/H5E.c ./src/H5Epublic.h Added H5E_RAGGED as a major error number. ./bin/release Checks the MANIFEST file against `svf ls' on systems that have it. ./bin/trace Fixed a bug that caused arguments of type `void *x[]' to not be handled. ./src/H5.c Removed unused variables and changed a couple types to fix compiler warnings. Added tracing support for ragged array object ID's and arrays of pointers. ./src/H5D.c H5Dcreate() will complain if either of the property lists are invalid (instead of using the default). ./src/H5D.c ./src/H5Dprivate.h Split H5Dget_space() into an API and internal function so it can be called from the new ragged array layer. ./src/H5Fistore.c Fixed warnings about unsigned vs. signed comparisons. ./src/H5Flow.c Fixed a warning about a variable being shadowed in the MPI-IO stuff. ./src/H5Iprivate.h ./src/H5Ipublic.h Added the H5_RAGGED atom group. ./src/H5Shyper.c Fixed some freeing-free-memory errors that resulted when certain arrays were freed but the pointers were left in the data structures. I simply set the pointers to null after they were freed. ./src/H5Sprivate.h ./src/H5Sselect.c Split the H5Sselect_hyperslab() function into an API and a private function so it could be called from the ragged array layer. Added H5S_SEL_ERROR and H5S_SEL_N to the switch statements to get rid or compiler warnings. ./src/H5Tconv.c Removed a misleading comment. ./test/bittests.c Fixed a warning about a printf(). ./test/cmpd_dset.c Fixed warnings about unused variables because of test #11 being commented out. ./bin/trace Shortened the right margin for the output to allow room for the `);' at the end of the TRACE() macros.

The serialized information for all types of selections follows this format:
<type of selection> = uint32
<version #> = uint32
<padding, not-used> = 4 bytes
<length of selection specific information> = uint32
<selection specific information> = ? bytes (depends on selection type)

[svn-r925] Changes since 19981116 ---------------------- ./INSTALL.parallel [NEW] We're beginning to unify some of the parallel installation steps. This file will contain general information for installing the parallel library. It's not complete yet. ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] Check for xdr_int() in libnsl required on Solaris when linking with hdf4. It's found on the Irix system I tested which complains that `-lnsl' didn't resolve any symbols. Oh well. Fixed the order of searching for libdf and libmfhdf for hdf4 linking. ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] ./src/H5Z.c Check for compress() in libz in order to find older versions of the library that will still work for hdf4. Added a separate check for compress2() that hdf5 will use. ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] ./src/H5.c ./src/H5private.h ./src/H5A.c ./src/H5B.c ./src/H5Bprivate.h ./src/H5D.c ./src/H5F.c ./src/H5Farray.c ./src/H5Fcore.c ./src/H5Ffamily.c ./src/H5Fistore.c ./src/H5Flow.c ./src/H5Fmpio.c ./src/H5Fprivate.h ./src/H5Fsec2.c ./src/H5Fsplit.c ./src/H5Fstdio.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5Oattr.c ./src/H5Ocomp.c ./src/H5Ocont.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Ofill.c ./src/H5Olayout.c ./src/H5Omtime.c ./src/H5Oname.c ./src/H5Oprivate.h ./src/H5Osdspace.c ./src/H5Oshared.c ./src/H5Ostab.c ./src/H5R.c ./src/H5RA.c ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Snone.c ./src/H5Spoint.c ./src/H5Sprivate.h ./src/H5Sselect.c ./src/H5T.c ./src/H5Tbit.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5V.c ./test/bittests.c ./test/gheap.c ./test/hyperslab.c ./test/istore.c ./test/tmeta.c ./test/trefer.c ./test/tselect.c ./tools/h5debug.c ./tools/h5tols.c Added checks for Posix.1g types like `int8_t'. If not defined then H5private.h defines them. Changed all `int8' etc. to `int8_t'. ./src/H5A.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5I.c ./src/H5P.c ./src/H5R.c ./src/H5RA.c ./src/H5S.c ./src/H5T.c ./src/H5TB.c ./src/H5Z.c Calling H5*_term_interface() resets interface_initialize_g to FALSE so a subsequent call to H5open() (implied or explicit) reinitializes global variables properly. ./src/H5private.h ./src/H5Oefl.c ./src/H5S.c Changed MAX_SIZET, MAX_SSIZET, MAX_HSIZET, and MAX_HSSIZET to SIZET_MAX, SSIZET_MAX, HSIZET_MAX, and HSSIZE_MAX to they match the Posix.1 constants in <limits.h>. ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5detect.c Added 36 more integer hardware conversion functions to the type conversion table for conversions to/from `long long' and `unsigned long long'. The `long long' names will be changed shortly to make them portable to Win32. Changed H5T_init() to H5T_native_open() and added an H5T_native_close() to open and close the predefined native data types. Increased the initial size of the type conversion table from 64 to 128 entries. Reordered the 90 new integer conversion functions so the names that are printed favor `int' over `short' or `long' when two of them are the same. ./test/dtypes.c Added hardware and software integer conversion tests for the 56 functions I added recently but not the additional 36 checked in this time. That will come next. Call H5close() after each test so type conversion statistics are easier to follow. Try this: $ HDF5_DEBUG=t ./dtypes Added more debugging output for when things go wrong. ./src/H5private.h Removed trailing carriage-returns inserted by broken operating system ;-)

Puts a list of the hyperslab blocks into the user's buffer. The blocks
start with the 'startblock'th block in the list of blocks and put
'numblocks' number of blocks into the user's buffer (or until the end of
the list of blocks, whichever happen first)
The block coordinates have the same dimensionality (rank) as the
dataspace they are located within. The list of blocks is formatted as
follows: <"start" coordinate> immediately followed by <"opposite" corner
coordinate>, followed by the next "start" and "opposite" coordinate, etc.
until all the block information requested has been put into the user's
buffer.
No guarantee of any order of the blocks is implied.

DESCRIPTION
[svn-r1139] Added code for H5Rget_object_type
1999-03-12 15:05:43 -05:00
Puts a list of the hyperslab blocks into the user's buffer. The blocks
start with the 'startblock'th block in the list of blocks and put
'numblocks' number of blocks into the user's buffer (or until the end of
the list of blocks, whichever happen first)
The block coordinates have the same dimensionality (rank) as the
dataspace they are located within. The list of blocks is formatted as
follows: <"start" coordinate> immediately followed by <"opposite" corner
coordinate>, followed by the next "start" and "opposite" coordinate, etc.
until all the block information requested has been put into the user's
buffer.
No guarantee of any order of the blocks is implied.

enough to hold the dataspace rank number of coordinates. The bounding box
exactly contains the selection, ie. if a 2-D element selection is currently
defined with the following points: (4,5), (6,8) (10,7), the bounding box
with be (4, 5), (10, 8). Calling this function on a "none" selection
returns fail.
The bounding box calculations _does_ include the current offset of the
selection within the dataspace extent.

[svn-r1132] Dataset region references are now finished and working correctly. Also, there are five new API functions for querying selections: H5Sget_select_hyper_nblocks - retrieves the number of hyperslab blocks in current hyperslab selection for a dataspace H5Sget_select_elem_npoints - retrieves the number of element points in current element selection for a dataspace H5Sget_select_hyper_blocklist - retrieves a list of the hyperslab blocks in current hyperslab selection for a dataspace H5Sget_select_elem_pointlist - retrieves a list of the element points in current element selection for a dataspace H5Sget_select_bounds - retrieves a n-dimensional bounding box containing current selection.

NAME
H5Sget_select_bounds
PURPOSE
Gets the bounding box containing the selection.
USAGE

hid_t dsid; IN: Dataspace ID of selection to query
hsize_t *start; OUT: Starting coordinate of bounding box
hsize_t *end; OUT: Opposite coordinate of bounding box
RETURNS
Non-negative on success, negative on failure

[svn-r1138] Changes since 19990304 ---------------------- ./config/*-aix4.* [REMOVED] ./config/*-aix4.x [NEW] ./config/solaris2.5 [REMOVED] ./config/solaris2.x [NEW] ./configure.in ./configure [REGENERATED] ./MANIFEST Changed the names of the IBM-SP2 config files by replacing the minor version numbers with an `x'. The solaris config warns about old versions of gcc. The RUNSERIAL value is set to the empty string by default. The config/* file (or user) can override it by setting it to some other value. The `--enable-parallel' with no flags turns on the HAVE_PARALLEL constant in the source code but doesn't add any MPI or MPI-IO libraries to the link line. If we are compiling for parallel then configure checks that we can actually link a very simple program. This has the benefit of detecting config errors before we waste time compiling the entire library. Configure recognizes `mpcc_r' as a parallel compiler. ./src/H5A.c ./src/H5Apublic.c Fixed some compiler warnings. Changed the return type of H5Aget_name() from hssize_t to ssize_t because the name can never be larger then memory.

[svn-r1277] Added additional checks into the dataspace code to determine if the hyperslabs being written out are contiguous in memory and on disk and write/read them as one I/O operation (if the datatypes don't require conversion). This should be a good performance boost for those situations. It's especially needed on the ASCI Red (TFlops) machine. - QAK (from Albert's account on modi4 :-)
