* [svn-r4355] Purpose:Quincey Koziol2001-08-141-60/+60
| | | | | | | | | | | | | | | | | | | | | | Code cleanup (sorta) Description: When the first versions of the HDF5 library were designed, I remembered vividly the difficulties of porting code from a 32-bit platform to a 16-bit platform and asked that people use intn & uintn instead of int & unsigned int, respectively. However, in hindsight, this was overkill and unnecessary since we weren't going to be porting the HDF5 library to 16-bit architectures. Currently, the extra uintn & intn typedefs are causing problems for users who'd like to include both the HDF5 and HDF4 header files in one source module (like Kent's h4toh5 library). Solution: Changed the uintn & intn's to unsigned and int's respectively. Platforms tested: FreeBSD 4.4 (hawkwind)

| | | | | | | | | | Code cleanups, mostly.. Description: Work on pacifying the SGI compiler to get the generic properties working correctly with --enable-parallel and --enable-fortran. It's not quite fixed yet, but I need to head home and these patches help... :-/ Platforms tested: IRIX64 6.5 (modi4)
* [svn-r4324] Purpose:Quincey Koziol2001-08-101-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | New Features! Description: Start migrating the internal use of property lists in the library from the older implementation to the new generic property lists. Currently, only the dataset transfer property lists are migrated to the new architecture, all the rest of the property list types are still using the older architecture. Also, the backward compatibility features are not implemented yet, so applications which use dataset transfer properties may need to make the following changes: H5Pcreate(H5P_DATASET_XFER) -> H5Pcreate_list(H5P_DATASET_XFER_NEW) and H5Pclose(<a dataset transfer property list>) -> H5Pclose_list(id) This still may have some bugs in it, especially with Fortran, but I should be wrapping up those later today. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4181] Purpose:Quincey Koziol2001-07-101-244/+267
| | | | | | | | | Bug Fix, Code Cleanup, Code Optimization, etc. Description: Fold in the hyperslab speedups, clean up compile warnings and change a few things from using 'unsigned' or 'hsize_t' to use 'size_t' instead. Platforms tested: FreeBSD 4.3 (hawkwind), Solaris 2.7 (arabica), Irix64 6.5 (modi4)
* [svn-r4038] Purpose:Quincey Koziol2001-06-211-7/+7
| | | | | | | | | | | | | Code clean/bug fix Description: H5FL (free-list manager) code currently is taking an hsize_t as the size of a memory block to allocate. On many machines, the size of an hsize_t is greater than the size of a size_t, potentially leading to incorrect memory allocations in rare circumstances. Solution: Changed hsize_t parameters and variables to size_t. Platforms tested: FreeBSD 4.3 (hawkwind)
* [svn-r3781] Purpose:Bill Wendling2001-04-051-13/+13
| | | | | | | | | | | | | | | | | | Update Description: Changed #include <hdf_file.h> construct to #include "hdf_file.h" so that the GNU compiler can more easily pick up the dependencies which it places in the .depend and Dependencies files. Also regenerated the Dependencies to go along with this. Platforms tested: Linux
* [svn-r3252] Purpose:Quincey Koziol2001-01-091-95/+93
| | | | | | | | | | | | | Code cleanup. Description: Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the extra warnings. Including a few show-stoppers for compression on IRIX machines. Solution: Changed lots of variables' types to more sensible and consistent types, more range-checking, more variable typecasts, etc. Platforms tested: FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)
* [svn-r3209] Purpose:Quincey Koziol2000-12-281-0/+3
| | | | | | | | | | | | | Updating debugging information for new features, etc. Description: Lots of the new features added to the library during the last year or so have been added without updating the debugging routines used by h5debug. Solution: Added more of the new features (although not all of them) to the debugging routines for h5debug. Also included some more information to expand on the information printed from h5debug. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r2722] Purpose:Quincey Koziol2000-10-241-2/+2
| | | | | | | | | | Feature symmetry Description: A while ago I needed to get the 'type' of data being accessed during writes to the VFL driver, so I put in code to get the information down there. Albert asked for the same information during reads, so I've added that in. Tested: FreeBSD 4.1.1 (hawkwind)
* [svn-r2652] Purpose:Quincey Koziol2000-10-101-1/+3
| | | | | | | | | | | | | | | Maintainance & performance enhancements Description: Re-arranged header files to protect private symbols better. Changed optimized regular hyperslab I/O to compute the offsets more efficiently from previous method of using matrix operations. Added sequential I/O operations at a more abstract level (at the same level as H5F_arr_read/write), to support the optimized hyperslab I/O. Platforms tested: Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)

* [svn-r2057] Purpose:Albert Cheng2000-03-241-1/+3
| | | | | | | | | | | | | | Bug fix for parallel mode. Description: H5FD_mpio_tas_allsame was called for all cases, even when MPIO is not used for access. That corrupted the internal file handle structure. Solution: Define a macro, IS_H5FD_MPIO(f), for testing if f is opened with MPIO access. Will call H5FD_mpio_tas_allsame only if this condition is true. Platform tested: O2K, both -64 and -n32 modes.

| | | | | | | | | | | | | | | | Fixed a read-uninitialized-memory error that resulted in the file containing small amounts (<8 bytes each) of uninitialized data. These padding areas (which are never read by hdf5) are initialized to zero now. ./MANIFEST ./src/H5Z.c ./src/H5Zdeflate.c [NEW] ./src/H5Zprivate.h ./src/H5Zpublic.h ./src/Makefile.in The zlib filter was moved to a separate file but is still automatically defined.

| | | | | | | | | | | | | | ---------------------- ./src/H5O.c [1.2, 1.3] Initialzed the padding area between the end of a message and the end of the space allocated for that message. This hopefully fixes an UMR error found by Quincey and prevents the file from containing unwanted data. ./tools/h5ls.c [1.2, 1.3] Fixed a bug where the `Data:' tag didn't get printed for attributes that have more than five values.

I've ported and tested the sec2, family, and core drivers and only ported the mpio driver (Albert will test it). So if you need MPIO I would recommend sticking with the previous version for a while. You will get a few compile warnings about split and stdio drivers not being implemented and possibly tracing information not inserted in some of the drivers. You can safely ignore them but I plan to fix them. I'm still working on the split driver because I just realized that it needs a part of the VFL that isn't written yet. Documentation is being updated also because there were some minor changes (mostly just name changes). It should be available on my web site later this week. ./MANIFEST ./src/Makefile.in ./src/hdf5.h ./src/H5Flow.c [REMOVED] ./src/H5Fstdio.c [REMOVED] ./src/H5Fsec2.c [REMOVED] ./src/H5Fsplit.c [REMOVED] ./src/H5Fmpio.c [REMOVED] ./src/H5Ffamily.c [REMOVED] ./src/H5Fcore.c [REMOVED] ./src/H5MFpublic.h [REMOVED] ./src/H5FD.c [NEW] ./src/H5FDcore.c [NEW] ./src/H5FDcore.h [NEW] ./src/H5FDfamily.c [NEW] ./src/H5FDfamily.h [NEW] ./src/H5FDmpio.c [NEW] ./src/H5FDmpio.h [NEW] ./src/H5FDprivate.h [NEW] ./src/H5FDpublic.h [NEW] ./src/H5FDsec2.c [NEW] ./src/H5FDsec2.h [NEW] Removed/added files for virtual file layer. ./bin/trace ./src/H5.c Removed unused public datatypes and added new VFL public datatypes.

Changed H5D_transfer_t to H5FD_mpio_xfer_t since the COLLECTIVE vs. INDEPENDENT transfer mode is specific to the MPIO file driver. Moved MPIO-specific stuff into the MPIO driver. ./src/H5B.c ./src/H5D.c ./src/H5Fprivate.h The H5F_mpio_* private functions were renamed and placed in the H5FDmpio driver except those which appeared in H5Smpio.c. ./src/H5E.c ./src/H5Epublic.h Added major error number H5E_VFL for virtual file layer related errors. ./src/H5F.c ./src/H5Fprivate.h Changed the logic that controls whether the boot block is written. Instead of assuming that the first call to write the boot block is only to allocate space, I've added a function argument which makes this explicit. Changed the way files are compared so that a driver-defined comparison function can be called. Files which belong to different drivers are always considered different. Removed H5F_driver_t since file drivers are now identified by object ID instead of a special non-user-extendible datatype. Removed all the hard-coded low-level file properties which have been replaced by the various file drivers. ./src/H5I.c ./src/H5Iprivate.h Added the H5I_inc_ref() which was removed a few months ago since we finally have a use for it. ./src/H5Ipublic.h Added the H5I_VFL object ID type to identify file drivers in the virtual file layer. ./src/H5MF.c ./src/H5MFprivate.h Moved all the allocation/deallocation code into the virtual file layer which allows file drivers to override much of it. ./src/H5P.c ./src/H5Ppublic.h Moved file driver-specific code into the various file driver files. The H5Pcopy() and H5Pclose() functions make calls into the virtual file driver to manage the memory for driver-specific file access and data transfer properties. ./src/H5private.h ./src/H5public.h The `haddr_t' type is now public. ./test/tfile.c Added a few more comments.

Thanks to Quincey, the comment no longer applied. ./src/H5T.c Relaxed the H5Tpack() a little so it would pack compound data structures that had non-transient atomic members. ./tools/h5ls.c Added a `-g' (or `--group') flag that causes information to be printed about the specified group instead of the group's contents. (sort of like Unix's `ls -d'). The `-g' can be used in combination with `-r' to print information about the group and its contents.

Also fixed a bug for undefined variable in H5D when H5S debugging is turned on but H5T debugging is turned off. ./config/conclude.in Fixed installation of header files for building in a directory other than the source directory.

Now it handles cycles between packages and isn't so sensitive to dependencies between packages. A package might shut down only to be restarted to process a request from some other package being shut down. Loops are detected after 100 iteractions and the shutdown is aborted with a message on standard error. This also makes it a lot easier to debug. ./src/H5A.c Fixed H5A_write() and H5A_read() so they pass a non-null background buffer to the conversion functions. This is necessary when an attribute has a compound data type. ./src/H5Flow.c ./src/H5Fprivate.h ./src/H5Fsec2.c Reindented new Win32 stuff. ./src/H5Odtype.c Fixed a bug when enumeration types are used in a compound data type. The byte pointer wasn't incremented after the type information was written. ./tools/h5ls.c Compound data types display their total size because it's not always obvious from looking at the members. Scalar attributes show their space as `scalar' instead of `{}'. The index value is not printed for attributes that have only a few values. Instead the word `Data:' is printed on the first line of attribute data. Named types display their data type only if verbose output was requested.

The bug I fixed was triggered by: 1. Create a file, F 2. Open an object, X 3. Close file F 4. Reopen file F for read/write. 5. Create and close some objects 6. Close file F 7. Close library (exit). Step 3 pended the close because object X is still open, but the file ID was removed from the H5I_FILE ID group. Step 4 created a new file because it didn't see any matching file on the H5I_FILE ID group. Step 5 extends the file. Step 6 writes the new file boot block to disk. Step 7 closes object X and completes the close from step 3, writing the old boot block information to disk. The new behavior is that step 3 moves the file from the H5I_FILE group to the H5I_FILE_CLOSING group. Step 4 searches both groups and finds the file. Step 5 extends the file using the same H5F_file_t struct as step 3. Step 6 closes the H5F_t struct opened in step 3 but not the H5F_file_t struct shared by steps 1 and 3. Step 7 closes object X which closes the H5F_file_t from step 1, flushing the boot block which was shared by all steps. ./src/H5F.c Added some bulletproofing to file reference counting and removed comments which no longer apply. Added H5F_flush_all() and H5F_close_all() which apply to all files. ./src/H5A.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5I.c ./src/H5Iprivate.h ./src/H5R.c ./src/H5RA.c ./src/H5S.c ./src/H5T.c Added the new H5I_free_t data type to describe the function type to be passed as the `free_func' argument to H5I_init_group(). ./src/H5I.c Bulletproofed the object removal functions. Removed comments which no longer apply. Changed global variable names so they don't violate the naming scheme. Added H5I_debug() that prints the contents of an ID group. Removed H5I_inc_ref() because it isn't used. Reindented a couple of functions. ./src/H5.c ./src/H5G.c ./src/H5Ipublic.h Changed H5I_MAXID to H5I_NGROUPS to better relect the fact that it's the total number of valid ID groups. ./src/H5Shyper.c Changed hyperslab offset arrays to signed quantities to get rid of warnings on DEC cluster. ./src/H5Flow.c ./src/H5Fprivate.h Changed the objno argument of H5F_addr_pack() to be unsigned to get rid of warnings on DEC cluster.

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 `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 ;-)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./bin/snapshot Made same fix as for the release script yesterday. ./src/H5D.c ./src/H5Dprivate.h ./src/H5G.c ./src/H5Gprivate.h ./src/H5Gpublic.h ./src/H5O.c ./src/H5Oprivate.h ./src/H5RA.c ./src/H5RAprivate.h ./src/H5T.c ./src/H5Tprivate.h Improved object type checking. Instead of determining the object type by trying to open each of the possible types, we keep a table of associations between object type number (like H5G_GROUP, H5G_DATASET, H5D_TYPE, and H5D_RAGGED) and an `isa' function that returns true if the object header has the right messages to make the object a particular type. This mechanism also allows specialization of object types by permitting an object to satisfy more than one `isa' function. Added `isa' functions for groups, datasets, ragged arrays, and committed data types. ./src/H5config.h.in Added HAVE_STAT_ST_BLOCKS. I thought this had already been added, but apparently not. ./tools/h5ls.c Removed system include files since they're already included by H5private.h and since I wasn't including them portably anyway. By default, 1-byte integer types are printed as integer values instead of ASCII characters. However, the `-s' or `--string' command-line switch causes the data to be interpretted as ASCII. String data types are always printed as character data. Ragged arrays are now identified as ragged arrays and h5ls doesn't descend into the group automatically. This uses the new object type specialization stuff. ./tools/h5tools.c ./tools/h5tools.h Added the ability to print 1-byte integer types as either ASCII or numeric data instead of always ASCII. The default is to print as numeric data.

The link count is displayed for `-v'. ./src/H5F.c Dumping of cache statistics is controlled by only the HDF5_DEBUG environment variable and not the H5F_ACC_DEBUG flag for H5Fopen() and H5Fcreate() since this makes it similar to the other debugging options. ./src/H5R.c ./test/ragged.c ./test/Makefile.in Tests pass but still a little work left to be done.

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mode to use for data transfer. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./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.

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.
