| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5.c Fixed a signed vs. unsigned comparison. ./src/H5D.c Setting a fill value of all zeros will cause the fill value to be written to the dataset instead of relying on the low-level file driver initializing unwritten areas with zero. ./src/H5D.c ./src/H5F.c ./src/H5Fprivate.h ./src/H5G.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5O.c ./src/H5T.c More file mounting stuff. ./src/H5I.c Fixed a bug where trying to close an invalid object id caused a core dump. For instance, H5Gclose(-1). ./MANIFEST ./test/Makefile.in ./test/mount.c [NEW] Mounting tests. ./src/H5R.c Fixed a couple (herr_t)NULL casts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5D.c Fill values are working for contiguous datasets now except there are two things that need more support from the data space layer, specifically the ability to form a selection from the difference of two selections. They are (1) extending an external contiguous dataset, (2) optimization by delaying the fill until after the first H5Dwrite(). Renamed H5D_allocate() to H5D_init_storage() since allocation is only part of the story. Added a data space argument so it doesn't have to query the space from the object header -- the space is always available in the caller anyway. Removed `#ifdef HAVE_PARALLEL' from a few places where it wasn't necessary. We don't need it around code that doesn't compile anything from mpi.h or mpio.h. ./src/H5Fistore.c Uncommented H5F_istore_alloc() for non-parallel and moved the `#ifdef HAVE_PARALLEL' just around Kim's barrier. ./src/H5Fmpio.c Wrapped a couple long lines. Got rid of two signed vs. unsigned comparison warnings. ./MANIFEST ./test/Makefile.in ./test/fillval.c [NEW] Added tests for fill values. The contiguous dataset extend test is disabled until H5S_SELECT_DIFF is implemented. ./tools/Makefile.in Fixed a bug where `make test' didn't build the executables first. This should cause the snapshots to start up again. ./Makefile.in Changed to build in `test' directory before `tools' directory. We want the library tests to pass before we even start considering the tools. You can still build and/or test the tools independent of the library tests passing.

Eventually we won't need the split ratios for H5D_allocate() because we'll build a completely full B-tree from the leaves up, but it might be useful to have other transfer properties at that level anyway. I always caled H5D_allocate() with &H5D_dflt_xfer. ./MANIFEST ./test/Makefile.in ./test/overhead.c [NEW] Added an `overhead' test run by `make timings'.

Internally, H5G_loc() was modified to return an H5G_entry_t* instead of an H5G_t* so it's more general. Among other things, this allows one to retrieve information about an object like a named type or dataset without knowing the name of the type or dataset: int get_nlinks (hid_t obj) { H5G_stat_t sb; if (H5Gstat(obj, ".", TRUE, &sb)<0) return -1; return sb.nlink; } ./test/gheap.c ./test/istore.c These files needed a couple of changes because they call some of the internal functions whose H5G_t arguments changed to H5G_entry_t. ./src/H5A.c Got rid of all the switch statements for getting symbol table entries for varous objects and replaced them with a call to H5G_loc() allowing attributes to automatically apply to any type of object that belongs to a file. ./test/Makefile.in Moved the ragged array tests from the normal list of tests to the `make timings' target. ./test/ragged.c Added rewrite tests -- rewrite the rows of a dataset changing the number of rows and the length of each row. ./test/mtime.c Added a test that checks that H5Gstat() can be called with a dataset as the first argument. ./src/H5S.c Added #ifdef HAVE_PARALLEL around code to check for the HDF5_MPI_OPT_TYPES environment variable because the global variable that gets set is #ifdef'd. ./bin/release bzip2 uses .bz2 as the file extension.

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.

Added timing calls around the data space calls when H5S_DEBUG is defined. ./src/H5S.c ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Spoint.c ./src/H5Sprivate.h Changed H5S_find() so it returns a table entry again instead of copying the data into a caller-supplied buffer. This allows the timers to be stored in the table and updated by the caller. Added H5S_register() to register new table entries and added entry creation to all the H5S selection methods. Also changed lots of global functions to static functions. ./src/H5Fistore.c Fixed a memory bug in the raw data cache.

If an object header has this message then it's value is updated with the current time whenever anything changes in the object header. ./acconfig.h ./configure.in Alas, there seems to be no standard way to convert a string time like 19980727122800 in UTC to a time_t since mktime() only converts local times to time_t. So I've modified the configuration to check for various ways of getting the time zone information: * Added checks for the `tm_gmtoff' field of `struct tm'. * Added a check for the `timezone' global variable. * Added a check for `struct timezone'. * Added a check for BSDgettimeofday(). * Added a check for gettimeofday() although it doesn't actually set the timezone argument on some systems. * Added a check to see if `tm_zone' is a member of `struct tm'. * Added a check to see if `tzname' is a global variable. * Added a check to see if `struct tm' is defined in time.h or sys/time.h. It's not difficult to get the right UTC modification message into the object header, but some systems might have problems getting the right time back out (Irix64 is one) and those systems will report zero for the H5G_stat_t.mtime from an H5Gstat() call as if the mtime message isn't even present. It will, however, continue to be updated as normal. ./src/H5G.c ./src/H5Gpublic.h The H5G_stat_t struct now contains an `mtime' field which will hold the object modification time. If the object has no object modification time then the `mtime' will be initialized to zero. Fixed a bug in H5G_stat() that caused the `objno' field of the H5G_stat_t to be set incorrectly on some machines. ./src/H5D.c Writing to external datasets fail if the hdf5 file is not open for writing. A modification time message is added to the dataset object header when it's created and H5O_touch() is called from H5D_write() to update that message. ./src/H5T.c Fixed a bug in H5Tget_member_dims() that caused a segmentation fault if one of the output array arguments was the null pointer. Relaxed the member dimension checking in H5Tinsert_array() so it can also be used for scalar members. ./test/Makefile.in Added additional file names to the `mostlyclean' target. ./tools/h5dump.c ./tools/h5tools.h Increased the temporary buffer size to 1MB. Added support for printing compound data types with array members. When printing H5T_NATIVE_CHAR and H5T_NATIVE_UCHAR we escape double quote characters. ./tools/h5ls.c Changed the output format a little because we were starting to get too much info to fit on a line. Without `--verbose' each object occupies one line of output. Otherwise, additional information is printed below the object name: object file address, comment, and modification time. If `--dump' is given then the data is printed after the other information. ./test/cmpd_dset.c Changed the way the dataset is initialized to be more uniform.

| | | | | | | | | | | | | | | | | 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-r438] Changes for PHDF5 to support extendable datasets.Albert Cheng1998-07-011-0/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

Added H5T_bit_get_d() and H5T_bit_set_d() which treat portions of a bit vector as an unsigned integer.

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.

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.

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. Extending a dataset through one handle will cause all other handles to the same dataset to get the new dataset size. ./src/H5S.c ./src/H5Sprivate.h Removed an unused argument from H5S_read() which duplicated information from the other argument. ./config/linux Made `--enable-parallel' the default on my system.

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. H5F_block_read H5F_block_write H5F_arr_read H5F_arr_write H5F_core_read H5F_core_write H5F_fam_read H5F_fam_write H5F_mpio_read H5F_mpio_write H5F_low_write H5F_low_read H5F_sec2_read H5F_sec2_write H5F_split_read H5F_split_write H5F_stdio_read H5F_stdio_write H5S_simp_fgath H5S_simp_fscat H5S_simp_read H5S_simp_write H5Fprivate.h: H5P.c: Removed access_mode field from struct H5F_access_t type. The access-mode was the initial design to control independent or collective I/O mode. It is now supported by the data transfer mode.

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.

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.

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.

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.
