* [svn-r482] Cleanup some code for final alpha-2 release.Albert Cheng1998-07-131-20/+27
| | | | | Allocate chunks only if MPIO is used. Do not attempt to run H5D_allocate if H5D_extend does not change anything.
* [svn-r480] Fixed an ugly bug by teaching the recursive hyperslab I/O code ↵Quincey Koziol1998-07-108-73/+284
| | | | | | | how to resume when a buffer gets full. Also removed the check for disallowing zero-dim extents on unlimited dimension datasets, per user's request.

| | | | | | | | | | | | | | | | | | | | | | ---------------------- ./README ./bin/release The first line of the README file is updated automatically by the `release' script to associate a date with a release number. For example: This is hdf5-1.0.9a released on 1998-06-09 18:00 UTC Please refer to the INSTALL file for installation instructions. ./src/H5public.h Release number incremented. This happens automatically now if you run the `release' script in `-batch' mode. I'll stop documenting changes to this file unless they're something other than a release number change. ./MANIFEST Added Elena's new files.
* [svn-r477] Changed the way file-space allocation for the data part of a dataset.Albert Cheng1998-07-094-63/+114
| | | | | | | | | | | | | | | | | H5D.c: Created a new function H5D_allocation to do allocation of all datasets. According to the storage layout, it calls the appropriate function. H5Fprivate.h: H5Fistore.c: H5F_istore_allocation now takes a dimension array, (old version used a space pointer) to determine how many chunks to allocate. Changed H5F_istore_get_addr to a private (static) function. No one outside of H5Fistore.c is calling it. Removed three forward declarations now that they are not needed. Tested platform: O2K
* [svn-r476] ./src/Makefile.inRobb Matzke1998-07-093-101/+101
| | | | | | | | Fixed missing H5Zpublic.h header file. ./src/H5Fistore.c Indented some printf's in the left margin so various C source tools work correctly.
* [svn-r473] Changes since 19980708Robb Matzke1998-07-0810-40/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5Fistore.c ./src/H5S.c Fixed places where `herr_t' functions returned NULL for failure: H5F_istore_get_addr() and printf(?!?) (probably because a printf() was in the first column :-/ so I don't know what function it really was that I fixed), and H5S_extent_copy(). ./src/H5Fprivate.h Added declarations for H5F_istore_get_addr() and H5F_istore_allocate(). ./src/H5S.c ./src/H5Sprivate.h Split H5Sset_extent_simple() into H5S_set_extent_simple() and replaced calls to the API function with calls to the internal function. Changed calls to H5Screate() to H5S_create() and H5Sclose() to H5S_close(). ./src/H5Shyper.c ./src/H5Spoint.c Removed unused labels and variable. ./src/H5T.c ./src/H5Tconv.c Changed calls to H5Tfind() to H5T_find(). ./src/H5TB.c Split function return type onto a separate line for five functions and added API tracing calls.
* [svn-r471] Changes since 19980708Robb Matzke1998-07-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./MANIFEST Alphabetized. `d' comes before `e' :-) ./bin/release Added the `-batch' option which causes the script to not ask questions and to automatically update the minor version number and set the patch level back to `a'. This is intended to be used for the daily snapshots: #! /bin/sh set -e cd ~/hdf5 make distclean make test bin/release -batch tar compress gzip bzip2 mv ./releases/* /repository ./src/H5Z.c Removed warnings about unused variables when the zlib.h header file is present but libz.a isn't. ./INSTALL ./configure.in ./doc/html/tracing.html Made API tracing the default (you still need to define the HDF5_TRACE environment variable to get results) and change the name from `--disable-tracing' to `--disable-trace' to make it consistent with the other switches. Changed `site config file' to `host config file' to match the documentation. ./doc/html/H5.user.html Added a reference to the `tracing.html' file.
* [svn-r469] Changes since 19980707Robb Matzke1998-07-089-58/+233
| | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./bin/trace ./src/H5.c Added tracing support for H5S_seloper_t and H5S_class_t. ./src/H5Sselect.c ./src/H5S.c Added tracing statements that weren't inserted previously because of formatting problems. ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h ./test/cmpd_dset.c Added H5Tinsert_array() for inserting an array member into a compound data type. Added support to the struct conversion function for member arrays. The index permutation is not supported yet in the conversion (source and destination must have the same permutations).
* [svn-r468] Fixed formatting problems and moved H5S_sel_iter_release calls ↵Quincey Koziol1998-07-084-47/+60

| | | | | | | | | | | Moved the source of H5S_extent_npoints before H5Sextent_npoints to reduce a compiler complaint. H5Shyper.c: H5Sprivate.h: H5Spublic.h: H5Sselect.c: Changed the parameter declarations of H5S_hyper_add and H5Sselect_hyperslab as originally intended as const hsize *.

That's another reason that we should be careful to add `/*out*/' after arguments that are output-only and `/*in,out*/' after arguments that are used for both input and output values. No internal function calls H5Pget_class() anymore. ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tpublic.h Added H5Tget_overflow() and H5Tset_overflow() so the application can query or set a function that will be called whenever an overflow occurs. Implemented as documented in previous e-mail except the overflow handler gets two buffers: one that contains the source value and one to receive the optional destination value. ./test/dtypes.c Tests overflow handler. ./src/H5.c We have to declare fdopen() because I'm getting errors when compiling on Irix64 even though we include <stdio.h> as documented in the fdopen() man page.

* [svn-r456] Changes since 19980706Robb Matzke1998-07-071-1/+1
| | | | | | | | | ---------------------- ./src/H5public.h If sizeof(size_t)==sizeof(long long) then we define `hsize_t' in terms of size_t to get rid of warnings on systems that treat `long long' the same as `long'.
* [svn-r455] Fixed various const and signed/unsigned problems and corrected ↵Quincey Koziol1998-07-076-36/+38

* [svn-r454] Changes since 19980702Robb Matzke1998-07-063-14/+38
| | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5T.c Prints statistics for no-op conversions also. For now, hardware floating point conversions may or may not raise SIGFPE depending on the hardware, operating system, etc. Software conversions never raise SIGFPE and use +Inf or -Inf for overflow. ./test/dtypes.c Catches SIGFPE and causes the test to be skipped. Better test for NaN. ./config/irix5.3 Removed the -U_POSIX_SOURCE because it was removed from the main makefiles. ./bin/trace ./src/H5S.c Fixed a typo that prevented tracing info from being added to new API functions.
* [svn-r451] Completely tore out existing dataspace API and replaced with code ↵Quincey Koziol1998-07-0623-1050/+4666
| | | | | | | | 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-r446] Changes since 19980702Robb Matzke1998-07-031-2/+14
| | | | | | | | | | | ---------------------- ./MANIFEST Added new files from testpar directory. ./config/commence.in Removed -D_POSIX_SOURCE because hdf5 uses a couple of non-Posix things when certain debugging flags are switched on.
* [svn-r438] Changes for PHDF5 to support extendable datasets.Albert Cheng1998-07-014-2/+666
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | H5D.c: If a dataset, using chunk storage, is created/opened and if its data file is accessed via MPIO, allocate file space for the chunks immediately. Also do the allocation when a dataset is extended. Must do it at these points because H5Dcreate, H5Dopen and H5Dextend are collective calls in MPIO access mode and are the only chance to get all MPI processes to synchonize their meta-data. Also disallow opening/creating datasets with compression option if MPIO is used. Not easy to support concurrent compression writes in an efficient way. But read-only access should be fine. Will implement that later. H5F.c: Disable file cache if MPIO is used by forcing cache size and number of elements to zero. H5Fistore.c: Added two new routines, H5F_istore_get_addr and H5F_istore_allocate. H5F_istore_allocate supports allocating file space for the chunks of a dataset. H5F_istore_get_addr returns the file space address of a chunk that has been allocated. Changed H5F_istore_read and H5F_istore_write to bypass the chunk cache read/write mechanism. Instead, they do read/write directly with the file for only the elements requested. (Some debug statements, enclosed by #ifdef AKC, are still in the file. I am still working on some code. They would be cleaned out soon.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5Tbit.c ./src/H5Tpkg.h Fixed a bug in H5T_bit_copy(). Added H5T_bit_get_d() and H5T_bit_set_d() which treat portions of a bit vector as an unsigned integer. Added H5T_bit_inc() that increments part of a bit vector and returns an indication of overflow. ./src/H5Tconv.c ./src/H5Tpkg.h ./test/dtypes.c Added a slow general floating point conversion which works so far on Intel, MIPS, and DEC but the test is turned off because a cast from double to float will cause a SIGFPE on some systems if an overflow occurs. Added fast hardware conversions between native floating point types. This function is also subject to the SIGFPE problem. ./src/H5detect.c Removed the exponent bias adjustment when the significand isn't normalized. This is now handled in the conversion functions instead. ./src/H5T.c Register new conversion functions. Plugged a memory leak in the library termination code. ./RELEASE Added a list of major changes since the first alpha. ./src/H5.c ./src/H5private.h ./src/H5A.c ./src/H5AC.c ./src/H5D.c ./src/H5Ffamily.c ./src/H5Fistore.c ./src/H5G.c ./src/H5Gprivate.h ./src/H5HG.c ./src/H5O.c ./src/H5T.c ./src/H5Tbit.c ./src/H5Tconv.c Fixed various compiler warnings on Irix64. ./src/H5MM.c Added PABLO_MASK to this file. ./test/chunk.c Removed a warning about memcpy().

The `x' was removed from the name to remind us of that: H5MM_xmalloc() -> H5MM_malloc(), etc. H5MM_calloc() takes one argument like H5MM_malloc() instead of two like calloc() because we almost always called it with `1' for one of the arguments anyway. The only difference between the two functions is that H5MM_calloc() returns memory which is initialized to zero. ./src/H5Gent.c ./src/H5Gprivate.h Removed H5G_ent_calloc() since it wasn't used. ./src/H5Fistore.c Fixed a bug found by Albert. Thanks, Albert! This fix combined with the changes to memory allocation prevent the library from failing an assertion if the application uses an unreasonable size for chunks (like Alberts 10000x10000x4). ./src/H5MF.c ./src/H5MFprivate.h Changed H5MF_free() to H5MF_xfree() since calling it with an undefined address is allowed.

This file describes how this all works. ./configure.in Added the `--enable-tracing' switch. If you use it then the library will include code to print API function names, argument names and values, and function return values. However, you must then turn on the tracing by setting the HDF5_TRACE environment variable to a file descriptor number. The default is `--disable-tracing' since enabling it causes a slight increase in library size and a slowdown resulting from an extra function call for each API function call (I couldn't even measure the slowdown :-) ./bin/trace NEW A perl script that synchronizes the H5TRACE() macro calls in the *.c files with the function return type and formal argument names and types. If you use GNU make and gcc then this will be done automatically, otherwise just invoke this script with the names of one or more .c files. You could do it by hand to, but encoding argument types is a little tricky at first. ./config/commence.in Added the $(TRACE) macro, which defaults to the no-op. Added -D_POSIX_SOURCE to the compiler command line. ./src/Makefile.in Override the default for $(TRACE). ./config/depend.in Automatically calls $(TRACE) to synchronize the H5TRACE() macros in any source file that changed. As with makefile dependencies, one way to force synchronization of all files is to remove the `.depend' file. ./MANIFEST Added new files. ./src/H5Eprivate.h Modified HRETURN_ERROR() and HRETURN() for tracing. ./src/H5.c ./src/H5private.h This is where the real tracing work really happens, in H5_trace(). ./src/H5A.c ./src/H5D.c ./src/H5G.c ./src/H5P.c ./src/H5S.c ./src/H5Z.c Added H5TRACE() calls to all API functions. You don't really need these changes if you don't want to merge your stuff because they can be generated automatically by going to the hdf5/src directory and saying ../bin/trace *.c ./src/H5T.c Added H5TRACE() calls. Other stuff below. ./src/H5E.c ./src/H5Epublic.h Added H5TRACE() calls. Created a type H5E_auto_t for the `func' argument of H5Eset_auto() and H5Eget_auto() to make those arguments easier to parse for tracing. It should also make it clearer for users that don't know how to read complicated ANSI data types. ./src/H5F.c Added H5TRACE() calls. Changed a couple `uintn' argument types in API functions to `unsigned int' since `uintn' part of the API. Changed a few "can't" and "cant" error messages to "unable to". ./src/H5Ipublic.h Removed H5_DIRECTORY from the H5I_group_t enum. It wasn't used anywhere. ./src/H5Tconv.c Removed an unused label. ./src/H5Fistore.c ./src/H5Oattr.c ./src/H5Odtype.c ./src/H5T.c ./test/dsets.c ./test/dtypes.c Fixed a warning about a variable possibly used before it's initialized. Added __unused__ to turn off some unused argument warnings that pop up when debugging is turned off and optimizations are turned on.

Also added MIN2() and MAX2() as aliases for MIN() and MAX(). ./test/tattr.c Removed some redundant `&' operators. ./configure.in ./src/H5config.h.in [regenerated] ./src/H5.c Fixed warnings on DEC where long double is the same as double.

Removed vestiges of PARALLEL_SRC no longer used by the makefiles. Albert came up with a better way (that actually works :-) ./src/H5D.c No code changes. Split a couple of long lines, refilled a couple multi-line comments. ./src/H5T.c ./src/H5Tpublic.h Fixed a bug reported by Jim Reus regarding conversion of compound data types whose members require conversions which are satisfied by as-yet unregistered soft conversion functions. Added H5T_IEEE architecture, but the funny-looking integer types will be changed to H5T_BE_ and H5T_LE_ architectures with the type names changed to match the H5T_NATIVE_ integers. Added an H5Tconvert() but it hasn't been documented or tested yet. ./src/H5Tconv.c ./src/H5Tpkg.h Registered conversion functions integer->integer (a general case) and integer->float (for a specific case). The integer->integer conversion depends on the bitvector operations which aren't finished yet and the int->float conversion hasn't been retested since it was borrowed from AIO. Don't look at them yet, they're ugly :-) ./src/H5detect.c Fixed a typo which caused the msb_pad field of an atomic type to not be initialized. ./test/dtypes.c Added a test for number conversions but it's commented out until the conversion stuff is truly working.

Any request >= the specified threshold will begin on an address which is a multiple of the specified alignment. Defaults are one for threshold and alignment. The alignment is done on relative addresses, so the size of the user block can affect the location of the data in the file. ./src/H5D.c ./src/dsets.c Added a test for, and fixed the data space caching bug in datasets.

| | | | | | | | | | | | | H5Fmpio.c was not part of the serial distribution. The auto- dependence configuration runs for serail distribution only, thus H5Fmpio.c has no dependence. It ended up not recompiled even when header files it depends on are changed. Solution: Changed configuration to always include this file. Enclosed the whole code in a big #ifdef HAVE_PARALLEL macro so that they would be compiled for parallel distribution only. Platform tested: O2K

| | | | | | | | | | | | | | Parallel File open has a racing condition if file already exists. Some processes see file exists, then truncate it (some system by remove and create). Some processes does not see the file exist, then attempt to just create it. Inconsistency. Solution: Instead of opening the file with COMM_SELF (which results in racing condition in routine that calls it), open it with the communicator in access_parms. (This assumes this access call must be called collectively.) Platform tested: O2K.

Currently, INDEPENDENT transfer is the default mode. Collective is supported for files opened via the MPIO driver. Specific changes to individual files follow. H5D.c: Replaced previous kludge of passing xfer_mode via the file access_mode with xfer_mode function parameter all the way to the low level I/O drivers. H5Dprivate.h: The H5D_xfer_t.xfer_mode is now used in serial and parallel modes. Removed the "HAVE_PARALLEL" macro condition to support it. H5Dpublic.h: Added H5D_XFER_DFLT as a new value for H5D_transfer_t and removed the HAVE_PARALLEL condition macro to make the H5D_transfer_t definition available to both serial and parallel version. H5B.c: H5F.c: H5Farray.c: H5Fcore.c: H5Ffamily.c: H5Fistore.c: H5Flow.c: H5Fmpio.c: H5Fsec2.c: H5Fsplit.c: H5Fstdio.c: H5Gnode.c: H5HG.c: H5HL.c: H5O.c: H5Sprivate.h: H5Ssimp.c: debug.c: Added xfer_mode to the argument lists of the following routines to specify data transfer mode. Then updated calls to these routines with appropriate transfer mode. Whenever cases that collective mode is inappropriate (e.g. object header read-write, flush), H5D_XFER_DFLT is used. The H5D_XFER_DFLT mode is currently acting the same as the independent mode.

The access-mode was the initial design to control independent or collective I/O mode. It is now supported by the data transfer mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5A.c Named data types can have attributes. Fixed bugs where the API functions didn't check the return values of their internal counterparts and thus the automatic error reporting didn't work. Fixed some places where the error stack wasn't cleared after a function returned failure. Data types returned by H5Aget_type() are always read-only. If the `attr_num' argument of H5Aiterate() is null then it acts like H5Giterate() instead of failing -- it begins processing attributes with the first one. ./src/H5D.c We check for allocation overruns when scalar datasets are stored in external files. ./src/H5O.c H5O_modify() will fail if the message is >=16kB. ./src/H5Oattr.c Split some long lines ./src/H5T.c ./src/H5Tprivate.h Added H5T_entof() to support attributes on named types. ./src/h5ls.c Prints the names of attributes and their sizes. ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c ./test/gheap.c ./test/istore.c ./test/links.c ./test/shtype.c If the environment variable HDF5_NOCLEANUP is defined then the temporary files are not removed. The testhdf5 program still has the bug that it removes *.h5, clobbering test files from other programs... oh well. ./test/dtypes.c Added attribute tests.

| | | | | | | | | | | | | | | | | | | | ---------------------- ./html/Datatypes.html Updated documentation for named data types and type sharing. ./src/H5Farray.c Split a couple long lines. ./src/H5T.c The H5T_copy() demotes immutable types to read-only types so they're cleaned up properly and memory is not leaked. ./test/dtypes.c Modified to be more consistent with other tests. Removed all internal header files, constants, types, and functions calls since the API is now complete enough to test everything. Temporary files are now removed.

Fixed some data type memory leaks during error recovery. ./src/H5Dprivate.h Added H5D_typeof() similar to H5D_entof() that returns a pointer directly to the dataset's type. This is used by H5Tcopy() when invoked on a dataset (see below). ./src/H5Epublic.h Fixed typos in H5E_BEGIN_TRY and H5E_END_TRY macros. ./src/H5F.c Closing a file with objects still open reports the file name in the warning message. Removed unnecessary invalidation of shared data types. ./src/H5Gent.c ./src/H5Gpkg.h ./src/H5Gprivate.h Added `const' to some arguments. ./src/H5O.c ./src/H5Oprivate.h ./src/H5Oshared.c An object header message can now be a pointer to a message in some other object header. The pointer is to the first message of the appropriate type in the other object header and hard link counts are maintained automatically to prevent dangling pointers. The old global heap method of message sharing is also supported although nothing actually uses it. ./src/H5Oattr.c ./src/H5Ocomp.c ./src/H5Ocont.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Olayout.c ./src/H5Oname.c ./src/H5Osdspace.c ./src/H5Oshare.c ./src/H5Ostab.c Changed the data type for the shared message info struct to H5O_shared_t and added an extra initializer to the class methods struct for the set_share method. ./src/H5Odtype.c Added the ability to share data type messages by pointing to other object headers. ./src/H5T.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h Added named data types and changed the functionality of some API functions as follows: * The term `read-only' means that a type handle cannot be modified with functions like H5Tset_*() or H5Tinsert(). * The term `immutable' means the same as `read-only' with the added restriction that H5Tclose() cannot be called for the type. A transient type is made immutable by calling H5Tlock(). * Handles to named types are always read-only. * Handles to predefined types are immutable. * A transient type can be converted to a named type by calling H5Tcommit(). This function will fail if the type is already named or is immutable. * The API function H5Tcommitted() returns an indication of whether a data type has been commited (or is named). If H5Tcommitted() returns TRUE for a data type obtained by calling H5Dget_type() on a dataset, then the dataset is using a shared data type. * H5Topen() returns a handle to a named type. * H5Tcopy() always returns a handle to a modifiable transient type even when invoked on a named type. Also, when invoked on a dataset it returns a modifiable transient type which is a copy of the dataset's data type. * Using a named data type in the call to H5Dcreate() causes the dataset object header to point to the named data type, but using a transient type causes the type to be copied into the dataset's object header. * The data type returned from H5Dget_type() is a named data type or a read-only transient data type depending on whether the dataset points to a named data type. The old behavior, to return a modifiable transient type, is accomplished by overloading H5Tcopy() to operate on datasets (see above). * H5Tshare(), H5Tunshare(), and H5Tis_shared() have been removed from the API. The following features were *not* implemented because they need more discussion: * A named data type can be opened by applying H5Topen() to a dataset in which case the data type is the data type of the dataset (or the data type to which the dataset points if the dataset has a shared data type). * A named data type can have attributes like groups or datasets. * The members of a compound data type can point to named data types. ./src/h5ls.c Reports `Data type' for named data type objects in the file.

Use it like this: HDfprintf(stderr,"size is %Zd\n", (size_t)x); ./src/H5AC.c ./src/H5F.c ./src/H5Fprivate.h The maximum number of meta data objects that can be cached can be set from the application (but the library might not honor it every time; it's a hint). ./src/H5D.c Changed a warning message so it's not so alarming. ./src/H5Fistore.c Chunks can be cached. ./src/H5O.c ./src/H5Oprivate.h Added H5O_copy() and H5O_free() to copy and free messages. ./src/H5P.c ./src/H5Ppublic.h Added H5Pset_cache() and H5Pget_cache() and changed lots of "template" to "property list". ./src/H5Z.c ./src/H5Zpublic.h Miscellaneous little things to clean up. Mostly just removed H5Z_MAXVAL and added H5Z_USERDEF_MIN and H5Z_USERDEF_MAX. ./MANIFEST ./test/Makefile.in ./test/chunk.c [NEW] Added a performance test for chunk caching. It looks at the amount of I/O instead of timing because timing is partly dependent on the chunk size and I wanted a measurement that was a function of only the cache size. Run `chunk' with no arguments and then say `gnuplot x-gnuplot' to see the plots (press return between plots). Postscript files are created for each plot. ./test/big.c ./test/cmpd_dset.c ./test/extend.c ./test/external.c ./test/gheap.c Added H5F_ACC_DEBUG so we can see cache performance statistics.
