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 an error message. ./config/BlankForm ./config/dec-flags ./config/gnu-flags ./config/hpux10.20 ./config/hpux9.03 ./config/irix5.x ./config/irix6.x ./config/solaris2.x ./config/unicosmk Removed the H5F_OPT_SEEK and H5F_LOW_DFLT constants from the configuration since they're no longer applicable. The default file driver is always the sec2 driver and it always optimizes calls to lseek() or lseek64(). ./config/depend.in C preprocessor errors generated during automatic dependency building are sent to /dev/null to prevent them from appearing twice in the make output. ./src/H5AC.c ./src/H5B.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5Oattr.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Oshared.c ./src/H5T.c ./src/H5detect.c ./test/ohdr.c Changed H5F_ADDR_UNDEF to HADDR_UNDEF to be more consistent with the `haddr_t' datatype which is now a public type. ./src/H5D.c ./src/H5P.c ./src/H5Ppublic.h ./src/H5Tconv.c ./test/cmpd_dset.c ./test/dsets.c ./test/overhead.c ./test/tselect.c ./test/tvltypes.c The H5P_DATASET_XFER constant was changed to H5P_DATA_XFER because the properties apply to all types of I/O operations, not just datasets. ./src/H5B.c ./src/H5Bprivate.h ./src/H5D.c ./src/H5Dpublic.h ./src/H5F.c ./src/H5Farray.c ./src/H5Fistore.c ./src/H5Fprivate.h ./src/H5Fpublic.h ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5R.c ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Smpio.c ./src/H5Spoint.c ./src/H5Sprivate.h ./test/big.c ./test/h5test.c ./test/istore.c ./testpar/t_dset.c ./testpar/t_file.c ./tools/h5debug.c ./tools/h5ls.c Modified to work with the virtual file layer by calling H5FD_* functions instead of H5F_low_* functions and by passing file access and data transfer properties by object ID instead of pointer. 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.
* [svn-r1494] Lots of various bug-fixes on VL datatypes. VL datatype fields ↵Quincey Koziol1999-07-161-5/+1
| | | | | | | in compound datatypes aren't yet working, but other ways of using them (vlen atomic, vlen compound and vlen vlen atomic, etc.) are working.
* [svn-r1418] Modified H5Tconvert to require a dataset transfer property ↵Quincey Koziol1999-07-031-128/+130
| | | | | | | | | | | | | list ID as the final parameter (so that VL datatypes have a way to pass in the custom memory allocation routines). Fixed a conversion bug when VL fields were part of a compound datatype that was causing the no-op conversion routine to be used instead of the vlen routine. Added the H5Pset_vlen_mem_manager and H5Pget_vlen_mem_manager routines to allow users to provide their own custom memory allocation routines for VL data read in from the file and reclaimed with H5Dvlen_reclaim. Finished coding on H5Dvlen_reclaim so it works now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes since 19990618 ---------------------- ./configure.in ./configure [REGENERATED] Now that compound struct conversions don't make so many calls to convert their members I turned the H5T debugging back on by default (it will still be disabled in a production version). ./src/H5AC.c ./src/H5B.c Made it possible to turn off messages about debugging these two packages using the same method as for all other packages. Just supply an invalid file descriptor number or use the shell to redirect said descriptor to /dev/null like this: $ HDF5_DEBUG=99,ac,b 99>/dev/null a.out ./src/H5T.c Changed the name of the old compound conversion function from `struct' to `struct(no-opt)' to be more consistent with the new version named `struct(opt)'. Fixed a bug in H5T_cmp() that caused any two VL types to compare as being equal. Removed duplicate code for bitfield comparisons in H5T_cmp(). ./src/H5Tconv.c Relaxed some constraints in the new compound conversion function so it applies to more cases. Also eliminated a memcpy in a tight loop. ./test/cmpd_dset.c Added a `--noopt' command line switch which unregisters the optimized compound conversion so we can test the non-optimized version.
* [svn-r1364] Robb Matzke1999-06-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | Changes since 19990618 ---------------------- ./Makefile.in Running `make' in the top directory recurses into the examples directory also except if the make target is one of: lib, progs, check, test, _test, install, uninstall. ./examples/Makefile.in Changed programs into tests, which just means that `make tests' does what `make progs' used to do and that `make check' runs the executables. ./src/H5Tconv.c Fixed a typo in the unsigned-to-signed native converter for large types to small types. This fixes a bug on baldric and possibly other machines for the `dtypes' test. Also fixed a signed vs. unsigned warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes since 19990616 ---------------------- ./src/H5T.c ./src/H5Tconv.c All conversion functions take an extra argument called `stride' which is the number of bytes to advance the source and destination pointers after each element is converted. If the value is zero then the old behavior is preserved (source and destination values are packed). This feature was necessary to implement the compound datatype conversion optimizations and it causes a minor change to the API (application-defined type conversion functions take an extra size_t stride argument). ./src/H5Tconv.c An additional compound data type conversion function was added which is applied unless the destination type is larger than the source type. I'm measuring significant performance increases for certain operations: Test Name Struct-Conv Noop-Conv New(Old) MB/s New(Old) MB/s ---------- ------------- ------------- Reordering 2.062(0.3936) 54087(0.9047) Subsetting 2.901(0.6581) 40192(1.1100) Shrinking 1.976(0.3925) 33628(1.1500) ---------- ------------- ------------- ./test/dtypes.c Added various compound datatype conversion tests. Fixed return values from functions. ./src/H5T.c Conversion timers are updated only if H5T debugging is turned on a runtime (in addition to compile time). This allows the data type layer to be compiled with debugging support without having to pay a big runtime penalty if the debugging isn't actually used. ./src/H5A.c ./src/H5D.c ./src/H5Ofill.c ./src/H5P.c ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h Added the stride argument to the H5T_convert() calls. The stride is always zero, which means that the source and destination data values are packed. ./configure.in ./configure [REGENERATED] If API tracing is turned off then libhdf5.settings will say `no' instead of nothing. ./test/flush1.c ./test/flush2.c Added better error messages in a couple places.
* [svn-r1311] Changes since 19990607Robb Matzke1999-06-071-1/+3
| | | | | | | | | | | | | | | | | | | | ---------------------- ./tools/h5ls.c ./tools/h5tools.c Added support for printing bitfields and opaque data. ./test/dsets.c Added bitfield and opaque datasets to the output file so h5ls has something interesting to print. ./test/trefer.c Resync'd ./src/H5Tconv.c Fixed bitfield conversion which resulted in possible garbage in high-order bits of destination when the destination type is larger than the source type. Thanks for spotting it, Quincey.
* [svn-r1305] Checkpointing the VL datatype code. I believe the core ↵Quincey Koziol1999-06-041-0/+208
| | | | | | | | functionality is here, accessed with H5Tvlen_create, but I need to start writing tests now. Also the more esoteric API calls (such as H5Tget_vlen_buf_size and the memory management calls) aren't implemented yet.
* [svn-r1292] Changes since 19990430Robb Matzke1999-06-021-0/+207
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- Remove changes from CVS ./bin/release Added a `--nocheck' switch which causes the script to not check the contents of the MANIFEST file against CVS. This is sometimes useful when you need to make a quick snapshot but the MANIFEST file is not quite up to date. ./src/H5D.c Removed warnings for unused variables ./src/H5Fprivate.h Removed the WIN32 definition for `uint' and changed the data type for `eof_written' from `uint' to `uintn'. Shouldn't this really be `hbool_t'? ./src/H5Odtype.c ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tpublic.h ./test/dtypes.c ./doc/html/H5.format.html Added support for bitfields and opaque data types.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./tools/h5ls.c Added a `--address' (`-a') switch which causes h5ls to display file addresses for raw data. For contiguous datasets it's just a nice simple number, but for chunked datasets it's a list of logical dataset coordinates, file addresses, filter masks, and storage sizes. Changed `--dump' switch to `--data'. ./src/H5D.c ./src/H5F.c ./src/H5Fprivate.h Enhanced the indexed-storage B-tree iterator so it can dump raw data addresses (and other info) to the standard error stream. Added H5Ddebug() so h5ls has a way to dump addresses for datasets. I'm not sure what else this API function should do, so I think we should discuss it before we document it. So far, h5ls is the only thing that uses it, and we can easily change that. ./src/H5Tconv.c ./test/dtypes.c Finally had a chance to verify Paul's H5T_conv_s_s (general string to string conversions) bug fixes and incorporate them into H5T_conv_f_f (general floating-point to floating-point conversions) and H5T_conv_i_i (general integer to integer conversons). Thanks Paul. ./src/H5D.c ./src/H5S.c ./src/H5Sprivate.h Added performance timers around data space read and write callbacks. They were already there for the gather/scatter callbacks. The timings for read/write callbacks are displayed along with gather/scatter when data space debugging is turned on. ./bin/iostats Updated to print totals. Added a `--fast' option that doesn't do any output except the totals and is much faster. ./bin/trace Changed __unused__ to UNUSED to match source code. ./config/gnu-flags Updated error message for pgcc. I've sent bug reports to the pgcc people but the new version still has the same bug. ./configure.in ./config/conclude.in ./config/depend.in Fixed dependencies for non-GNU makes when run in a directory other than the hdf5 source tree. Updated GNU `make dep' rules to copy the distributed dependencies for non-GNU makes into the source tree when run in some other directory.

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.

* [svn-r1119] Purpose:Paul Harten1999-03-081-2/+4
| | | | | | | | | | | | | | | | | | | Bug fix Problem: On Solaris2.5, once the library has been compilied with any type of optimization, a bus error comes up in the "dtypes" test. Solution: The problem appears to be in the compilers' version of memcpy() that is used when optimized. Instead of substituting HDmemmove(), on Solaris, the problem is also taken care of by preparing the second argument to HDmemcpy(). The datatype pointer is copied to a separate char pointer which is then used as the second argument to HDmemcpy(). For some reason, it isn't enough to simply cast the datatype pointer. Platform tested: Solaris2.5

| | | | | | | | | | | | | | | | | Bug fix Problem: On Solaris2.5, once the library has been compilied with any type of optimization, a bus error comes up in the "dtypes" test. Solution: The problem appears to be in the compilers' version of memcpy() that is used when optimized. Apparently, the same optimization problem is not associated with the similar function memmove(). So, as a solution to this problem, memmove() is substituted in for memcpy(). Platform tested: Solaris2.5

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./INSTALL Added instructions for using other compilers on Irix platforms. ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] ./src/H5private.h The presence of <sys/sysinfo.h> and <sys/proc.h> is only checked on DEC/Alpha because there are too many problems including these headers on other systems. ./config/irix6.x ./config/irix64 Removed `-ansi' and added a comment. Converting an ASCII UTC date and time to a time_t value is not defined by ANSI or Posix but is available if we don't use `-ansi'. This allows the dataset modification time messages to be read properly by H5Gget_objinfo(). ./src/H5Tconv.c Fixed a compiler warning. ./test/dtypes.c ./test/hyperslab.c ./test/istore.c Fixed compiler warnings in printf() statements.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./INSTALL Added warnings and a disclaimer about GNU, DEC, Irix64, and NT compilers that generate incorrect machine code. ./configure.in ./src/H5private.h Detects and includes <sys/param.h> which is needed on FreeBSD before <sys/proc.h> even though we only really using anything from <sys/proc.h> on the DEC Alpha. ./config/irix64 Turned off warnings for duplicate definitions from the linker because -lnsl on irix has the same stuff in it as -lc. ./config/irix6.x Split up the CC and CFLAGS settings like with irix64 so that compilers besides `-n32' can be used. ./bin/snapshot The snapshots are tagged with names like hdf5-1_1_52 which is similar to the way the releases are tagged (cvs doesn't allow dots in tags). ./test/dtypes.c ./src/H5private.h ./src/H5Tconv.c Fixed some alignment violations on the DEC when using high optimization levels. The DEC incorrectly optimizes certain memcpy() and memmove() calls when the source argument is not word aligned if the call looks like it's copying an atomic data type. ./test/hyperslab Worked around code generation bugs in the Irix64 Mongoose 7.00 compiler by casting some `unsigned long' values to `unsigned' in an expression. ./src/H5Ocomp.c Fixed a place where %d was used to print a size_t.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix Problem: Depending on how the string size changes, different buffers are used when copying from one array of strings to another array of strings. An ASSERTION() is set up to check the validity of the buffer being used for each element of the string array being copied. This ASSERTION() fails for a 10 element string array of string length 42 being copied to a 10 element string array of string length 50. Solution: The overlap variable (olap) is calculated slightly differently. Also, since olap and nelmts are unsigned types, the conditional assignment: d = elmtno >= nelmts-olap ? dbuf : dp should be rewitten as: d = elmtno+olap >= nelmts ? dbuf : dp This same problem/solution may exist in H5T_conv_i_i(), and H5T_conv_f_f().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5.c ./src/H5private.h Renamed `library_initialize_g' to `H5_libinit_g' to make it conform to our naming scheme. ./src/H5I.c Fixed a bug in H5I_dec_ref() that caused the return value to always be zero instead of the new reference count. ./src/H5.c ./src/H5Odtype.c ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h Added support for enumeration data types. ./src/H5RA.c Renamed H5T_insert() to H5T_struct_insert() and added H5T_enum_insert(). ./src/H5RA.c ./src/H5Shyper.c Added casts to size_t for the third argument of memcpy() to shut up a warning message from insure++. ./src/H5T.c Changed "can't" to "unable to" in some error messages to be more consistent. ./src/H5detect.c If fork() or waitpid() are unavailable then we assume no alignment constraints. Hopefully this is the case only on NT and Intel CPU's don't have alignment constraints. ./src/H5public.h Include <limits.h> because the H5T_NATIVE_CHAR macro needs the definition for CHAR_MIN.

Performance testing shows that under certain circumstances (like data type conversions of compound types) the H5_timer functions, although only a few lines each, contribute a fairly large percent to the execution time. ./src/H5T.c ./src/H5Tpkg.h ./src/H5Tpublic.h Improved the H5Tunregister() function to make unregistering more flexible. It takes the same arguments as H5Tregister() but also accepts wild cards. All conversion functions that match the H5Tunregister() search criteria are removed from the global type conversion table. The H5Tregister_hard() and H5Tregister_soft() were combined into a single function called H5Tregister() which is the counterpart to H5Tunregister(). A new `persistence' argument was added to differentiate between the two types of conversion functions. The application is allowed to register a hard conversion function for the no-op conversion path although the library isn't obligated to call it (it usually does). This is mostly for completeness, but the application might use it to help determine if the raw data pipeline was able to use the optimized path for the case when no type conversion is necessary. The library doesn't allow this path to be unregistered although the application can redefine it as often as it likes. Fixed the type conversion tables in preparation for MT-safety and to fix previosly-known design bugs wrt. unregistering conversion functions or changing the C function associated with a conversion path. The MT-safety stuff is documented in a separate white paper. Increased the conversion function debugging name from 9 characters to 31 characters so the output can be more descriptive. Moved conversion path statistics from the H5T_cdata_t member into the conversion path itself. This makes H5T_cdata_t contain only application-visible data structures. ./src/H5A.c ./src/H5D.c ./src/H5Ofill.c ./src/H5P.c ./src/H5T.c Improved the way type conversion functions are called so the caller doesn't have to check for data type debugging and increment type conversion timers and statistics. Changed check for no-op conversion since it is now application-definable and there may even be more than one definition at a time in a multi-threaded application (one thread might be using the no-op conversion path when some other thread changes its definition -- the first thread still sees the original defintion until it's done with the operation). ./doc/html/Datatypes.html Updated the user guide to reflect the changes to data type conversion registration functions. ./bin/trace ./src/H5.c Added tracing support for the new H5T_pers_t data type. ./test/dtypes.c Added printf to display alignment value if non-aligned data types are being tested. ./test/h5test.c Modified the H5Tunregister() calls to use the new arguments. All 94 of those calls can be replaced by a single call to the new H5Tunregister() function. ./src/H5.c Added HAVE_GETTIMEOFDAY around an auto variable and initialized the elapsed time to zero when gettimeofday() is not available. ./src/H5F.c ./src/H5Fprivate.h ./src/H5P.c Added an H5*_init() functions which do the same thing as H5*_init_interface() but can be called from other packages and don't do anything if the interface is already initialized. This fixes a couple memory leaks in applications that repeatedly close and open the library with H5close(). ./src/H5Tconv.c Optimized some data alignment code in the hardware conversion functions. Hardware conversions accumulate statistics about source and destination data alignment and print that information when the conversion function is unregistered (usually when the application exits) if data type debugging is compiled into the library and enabled at run-time. The conversion caching was cleaned up for the compound data type conversion function. It now caches conversion paths in a manner that will be MT-safe and is much simpler than the old method. Also cleaned up some array index maps. ./src/H5detect.c Fixd mispelling of alingemnt. ./src/H5private.h Changed `TRUE' to `1' in assignment to interface_initialize_g in FUNC_ENTER macro definition. ./tools/testh5dump.sh Completely rewritten to make it shorter, better documented, and conforming to most of the other test outputs. The comparison of the actual output with the expected output is insensitive to differences in white space. The test now passes for the first time on Linux where the output width wasn't as expected but the output was otherwise correct. ./tools/testfiles/tall-1.ddl ./tools/testfiles/tall-2.ddl ./tools/testfiles/tall-3.ddl ./tools/testfiles/tattr-1.ddl ./tools/testfiles/tattr-2.ddl ./tools/testfiles/tattr-3.ddl ./tools/testfiles/tattr-4.ddl ./tools/testfiles/tcomp-1.ddl ./tools/testfiles/tcomp-2.ddl ./tools/testfiles/tcomp-3.ddl ./tools/testfiles/tcomp-4.ddl ./tools/testfiles/tdset-1.ddl ./tools/testfiles/tdset-2.ddl ./tools/testfiles/tdset-3.ddl ./tools/testfiles/tdset-4.ddl ./tools/testfiles/tgroup-1.ddl ./tools/testfiles/tgroup-2.ddl ./tools/testfiles/tgroup-3.ddl ./tools/testfiles/tlink-1.ddl ./tools/testfiles/tlink-2.ddl ./tools/testfiles/tlink-3.ddl ./tools/testfiles/tlink-4.ddl ./tools/testfiles/tlink-5.ddl ./tools/testfiles/tslink-1.ddl ./tools/testfiles/tslink-2.ddl Changed `../h5dump' to just `h5dump'. ./config/alpha-dec-osf4.0 Added more warning and optimization switches to the native compiler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./MANIFEST Added tcompound2.{dmp,h5} and tdset2.{dmp,h5} used by the h5toh4 testing. ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] Added check for <sys/timeb.h> for Win32. Determines sizeof(char) just so we have a complete list of type sizes defined as preprocessor symbols. ./src/H5detect.c ./src/H5T.c ./src/H5Tpkg.h Detects alignment constraints. In order for this to work the operating system must not correct unaligned data (for instance, on the DEC Alpha one might need to say `uac p sigbus' before running H5detect). ./src/H5private.h Includes <signal.h> because it's needed by H5detect.c to detect alignment constraints. ./src/H5Tconv.c Added extra checks to all hardware conversion functions so they align data when necessary before the conversion. This slows down the conversions somewhat but they're still much faster than the software conversions. ./test/dtypes.c By setting a constant at the top of the source you can test conversions where the data is aligned on various byte boundaries. By setting a constant at the top of the source you can simulate architectures that have alignment constraints on architectures that don't. Changed typo SIZEOF_LDOUBLE to SIZEOF_LONG_DOUBLE in a few places.

Added a new H5T_NATIVE_CHAR type which has the same range, representation, and behavior as either H5T_NATIVE_SCHAR or H5T_NATIVE_UCHAR depending on the compiler and its command-line switches for the application source file which references H5T_NATIVE_CHAR. If source files are compiled with different switches then each source file will resolve H5T_NATIVE_CHAR appropriately so it matches the C type `char' in that source file. NOTE: THERE ARE OTHER DOCUMENTATION FILES THAT I DIDN'T CHANGE BECAUSE I CAN'T MODIFY THE SOURCE. ./test/extend.c Swapped two lines to prevent diagnostic messages from messing up the formatted output.

| | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5Tconv.c With my poor eyesight I missed the definitions of SCHAR_MIN and SCHAR_MAX in <limits.h> and used CHAR_MIN and CHAR_MAX incorrectly. I changed all occurrences of the latter to the former and the new hardware integer type conversions now work on Irix. ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] ./src/H5private.h ./src/H5.c ./test/h5test.c Added a wrapper for HDsnprintf() that just calls sprintf() if snprintf() isn't available. ./MANIFEST Added Paul's new h5toh4 files.

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.

Therefore, I've temporarily changed all occurrences of `long long' to `long_long' and then #define that in H5private.h based on the existence of `long long' or `__int64'. This gets rid of some #ifdef's in other parts of the code. The semantics of the hdf5 types are: *int8_t Exactly one byte *int16_t At least two bytes. We favor 32-bit integers over 16-bit integers if the 16-bit integer is 4-bytes wide (Cray) *int32_t At least four bytes. *int64_t At least eight bytes long_long The widest integral integer type The H5Smpio.c contains debugging code which is non-portable. ./tools/h5ls.c Changed the order native types are detected so we favor the name `int' over `short' or `long' if two of them are the same. ./config/conclude.in Added a rule to make test programs depend on the hdf5 library. This fixes a minor bug where changing H5detect.c and then running `make test' caused H5Tinit.c to not be recompiled and therefore the test files are not relinked.

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.

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 ;-)

Removed all the #ifdef WIN32 from the source and replaced them with OS-independent stuff. Specifics follow: Check for non-Posix.1 `st_blocks' field in `struct stat' which is used by the big file test to decide if the file system supports holes. If the st_blocks field isn't present then we just skip the test. Configure checks for <io.h> <sys/resource.h> <sys/time.h> and <winsock.h> and defines HAVE_IO_H, HAVE_SYS_RESOURCE_H, HAVE_SYS_TIME_H and HAVE_WINSOCK_H when they're found. Configure checks whether both <sys/time.h> and <time.h> can be included and defines SYS_TIME_WITH_TIME if so. Otherwise include only <sys/time.h> or <time.h> even if both exist. Configure checks sizeof(__int64) and defines SIZEOF___INT64 to the result or to zero if __int64 isn't defined. The source uses `long long' in preference to `__int64'. Removed null WIN32 definition for `inline' since such a definition already exists in H5config.h Protected gettimeofday() calls in debugging code with HAVE_GETTIMEOFDAY instead of WIN32. ./src/H5F.c ./src/H5Flow.c ./src/H5Fmpio.c ./src/H5Fsec2.c ./src/H5Fstdio.h ./src/H5P.c ./src/H5Tconv.c ./src/H5private.h Removed #include of system files from library source files and consolodated them into H5private.h where they're protected by various configuration macros (most of them were duplicated there already anyway). ./test/big.c ./test/chunk.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c ./test/fillval.c ./test/flush1.c ./test/flush2.c ./test/iopipe.c ./test/links.c ./test/mount.c ./test/mtime.c ./test/overhead.c ./test/ragged.c ./test/shtype.c ./test/unlink.c Protected system #include's with #ifdef's from H5config.h. Undefined NDEBUG since some of the tests rely on assert() to check return values. Removed WIN32 definitions for __unused__ since this can be controlled by the definition of HAVE_ATTRIBUTE in H5config.h ./test/testhdf5.h Removed the CLEAN_CMD definition because we no longer use it. Albert's cleanup() functions replaced it. ./test/fillval.c Initialized auto hid_t variables to fix warnings in error recovery code when data flow analysis is turned on in compilers. ./test/h5tools.c Initialized an auto variable to fix a compiler warning. ./test/chunk.c ./test/ragged.c The WIN32 had some unsigned variables changed to signed because the compiler generates warnings when coercing unsigned to double(?). I changed them back to unsigned because they really are unsigned quantities. If this the change was just to shut up extraneous warnings then perhaps a compiler flag can do the same; otherwise if the compiler generates bad code then we should supply a patch file instead messing up source code with bug work-arounds. ./src/H5detect.c Protected system #include's with #ifdef's from H5config.h thereby removing a WIN32. If getpwuid() doesn't exist (HAVE_GETPWUID) then we assume that `struct passwd' doesn't exist either (we don't really need it in that case). The H5T_NATIVE_LLONG and H5T_NATIVE_ULLONG are defined in terms of `long long' or else `__int64' or else `long' depending on what's available. ./src/H5Flow.c ./src/H5Ofill.c Added __unused__ to some function arguments that aren't used when assertions are turned off. ./src/H5V.c Changed an auto variable name in some hand-inlined code to get rid of a warning about the variable shadowing a previous auto.

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 string character set and padding method are saved to the hdf5 file instead of using defaults. Added conversion function from one fixed-length string type to another. ./test/chunk.c Fixed to work with new filter API

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

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

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.

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

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

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

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.
