HDF5 now uses automake 1.10.0, + autoconf 2.61, and libtool 1.5.22. MAM - 2007/7/25. + - Changed default fortran compiler to g95 when gcc is used. - AKC + 2007/2/17. + - 'make check-vfd' can now be run from the top level directory. Not all + tests that 'make check' invokes work with certain Virtual File Drivers, + so those tests have been skipped. - MAM 2006/7/17 + - Added the variable HDF5TestExpress to control how long tests run. + Setting it to a value between 0 and 3 controls how thoroughly the + library is tested, with 0 being an "exhaustive run" and 3 being a + very quick "smoke test." 1 (a "full run") is the default. + -JML 2006/6/21 + - If both shared and static libraries are installed, now both will be + tested during 'make install'. -MAM 2006/06/21 + - Added support to explicity enable stream_vfd or shared libraries + when using parallel via the '--enable-stream_vfd' and + '--enable-shared' options, respectively. If not explicity defined, + These settings default to enabled when parallel is not used, + and disabled when parallel is used. -MAM 2006/06/17 + - Remove the flexible parallel code and the --enable-fphdf5 + configure option, it was never up to production standards + anyway. -QAK 2006/4/20 + - Added a macro hdf5_mpi_special_collective_io_works to filter out + some mpi-io packages that don't support collective IO for no IO + contributions in some processes. -KY 2006/2/16 + - Added -shlib option to link against installed shared libraries to + h5c++ and h5fc. -JML 2005/11/1 + - Added --enable-build-all option to configure, which only developers + should need to use. -JML 2005/10/24 + - Configure uses the 'TR' variable to let the user override the path + to the 'tr' utility. -JML 2005/10/17 + - Configure can recognize -lmpich as a form of MPI library. -AKC- + 2005/9/28. + - MD5 checksumming has been added to snapshot releases. Release + tarballs will be accompanied by .md5 checksum files, which can + be verified using the md5sum utility. -JML 2005/9/6 + - Some configure flags are incompatible (e.g., the C++ APIs cannot + be built using the parallel version of HDF5). configure will now + output errors when some common incompatible features are used + together. -JML 2005/9/6 + - A new API function, H5Tis_hard(), was added to the library. It + checks if a conversion function is a compiler (hard) conversion. + SLU - 2005/9/6 + - t_mpi will run the test_mpio_derived_dtype by default unless it is + known not working (indicated by macro H5_MPI_COMPLEX_DERIVED_DATATYPE_WORKS + not defined.) -AKC- 2005/8/23. + - Test execution has changed in a number of ways: + When make is invoked in parallel (using -j), sequential tests + are now executed as parallel make targets. This should make them + finish more quickly on machines with multiple processors. + Since test output is garbled when they are executed by parallel make, + tests now dump their output to foo.log files and foo.logsh files + (for test scripts). These logs are printed to the screen only + when a test fails or when all tests in the current directory have + completed successfully. + When tests pass, they will create a foo.chkexe file. + This prevents the test from executing again until the test or + main library changes. + All files generated by tests (*.chkexe, *.log, and any *.h5 files + created) can be removed by invoking 'make check-clean'. + Sequential and parallel library tests can now be invoked separately. + 'make check-s' will execute only sequential tests, and 'make check-p' + will execute only parallel tests. 'make check' will still execute + all tests. + -JML 2005/08/03 + - On windows, all.zip is deprecated. users should + read INSTALL_Windows.txt to know the details. + Reasons to deprecate all.zip: + 1. Avoid confliction for windows programmers + 2. Decrease size of CVS tree by adding all.zip + 3. Avoid using winzip as the intermediate step + --KY 2005/04/22 + - When HDF5 is created as a shared library, it now uses libtool's + shared library versioning scheme. -JML 2005/04/18 + - HDF5 now uses automake 1.9.5 to generate Makefiles.in. + This has a number of effects on users: + The Fortran compiler should be set using the environment + variable $FC, not $F9X. F9X still works, but is depreciated. + The output of make may be different. This should be only a + cosmetic effect. + make depened (or make dep) is no longer recognized, since automake + handles dependency tracking. + Some new configure options exist. --enable-dependency-tracking + and --disable-dependency-tracking are used to control automake's + dependency tracking. Dependencies are on by default *on most + platforms and compilers*. If --enable-dependency-tracking is + used, they will be enabled on any platform. However, this can + slow down builds or even cause build errors in some cases. + Likewise, --disable-dependency-tracking can speed up builds and + avoid some build errors. + Some make targets have alternate names. make check-install and + make installcheck do the same thing, for instance. + pmake on IRIX can be invoked from the root directory, but the + -V flag must be used to invoke it in any subdirectory or it + will give an error about undefined variables. + JML 2005/01 - 2005/03 + - Hardware conversion between long double and integers is also added. + SLU 2005/02/10 + - Started to support software conversion between long double and + integers. Hardware conversion will come very soon. SLU - 2005/1/6 + - Intel v8.0 compiler would infinite loop when compiling some test + code with -O3 option. Changed enable-production default compiler + option to -O2. AKC - 2004/12/06 + - Long double is assumed to be a supported C data type. It is a + stanadard C89 type. AKC - 2004/10/22 + - The IA64 will use ecc as the C++ compiler by default. + - Added some initial support for making valgrind/Purify (or similar + memory checking products) happier by initializing buffers to zero + and disabling the internal free list code. To take advantage of + this, use the "--enable-using-memchecker" configure option when + building the library. QAK - 2004/07/23 + - Fixed the long compile time of H5detect.c when v7.x Intel Compiler + is used with optimization NOT off. AKC - 2004/05/20 + - Fixed configure setting of C++ for OSF1 platform. AKC - 2004/01/06 + - Prefix default is changed from /usr/local to `pwd`/hdf5. + AKC - 2003/07/09 + + Library: + -------- + - Removed size restrictions on attributes, when using the "latest" + version of the file format. - QAK - 2007/02/21 + - Relaxed restrictions on attribute operations to allow a file ID to + be used as the "location ID". If a file ID is used, the attribute + operation will occur on the root group of the file. + - QAK - 2007/02/09 + - Enabled the CORE driver to read an existing file depending on + the setting of the backing_store for H5Pset_fapl_core and file + open flags. - SLU - 2006/11/30 + - Added new H5Gget_info_by_idx() routine to query the information about + a group according to the order within an index. + - QAK - 2006/11/27 + - Added new H5Gget_info() routine to query the information about a + group by name. + - QAK - 2006/11/27 + - Added new H5Oget_info_by_idx() routine to query the information about + an object in a group according to the order within an index. + - QAK - 2006/11/26 + - Added new H5Oget_info() routine to query the information about an + object in a group by name. + - QAK - 2006/11/26 + - Added new H5Oopen_by_idx() routine to open an object in a group + according to the order within an index. + - QAK - 2006/11/20 + - Added new H5Literate() routine to iterate over links in a group + according to the order within an index. + - QAK - 2006/11/20 + - Added new H5Ldelete_by_idx() routine to delete a link according to + the order within an index. + - QAK - 2006/11/13 + - Added new H5Lget_val_by_idx() routine to query the value of a soft link + according to the order within an index. + - QAK - 2006/11/13 + - Added new H5Lget_name_by_idx() routine to query the name of a link + according to the order within an index. + - QAK - 2006/11/12 + - Added new H5Rget_name() routine to determine the name of the object + that a reference points to, as long as the object is still + reachable in the group hierarchy. + - QAK - 2006/11/10 + - Added new H5Lget_info_by_idx() routine to query the link information + according to the order within an index. + - QAK - 2006/11/10 + - Added feature to H5Iget_name to allow retrieving the name of any + object's ID, as long as the object is still reachable in the + group hierarchy. + - LA - 2006/11/01 + - Added External and User-defined links. + External links are links from one HDF5 file to another; they + require both the name of the file and a path within that file. + User-defined links allow users to supply callback functions + for link traversals, allowing links to exhibit essentially + any behavior. + External links are a kind of user-defined link, so their default + behavior can be overridden by the user. + -JML 2006/8/23 + - Added H5Oopen and H5Oclose for opening objects of unknown type + (as link callback functions do). + -JML 2006/8/23 + - Added H5Oopen_by_addr, H5Oincr_refcount, and H5Odecr_refcount for + opening objects by address. Be very careful with these! + -JML 2006/8/23 + - Added H5Fget_intent to get the "intent" of a file (whether it + was opened with read-write access or read-only. + -JML 2006/8/23 + - Added Link Access Property Lists. They currently contain two + properties, nlinks (H5Pget/set_nlinks) and elink_prefix + (H5Pget/set_elink_prefix). nlinks controls how many soft and + user-defined traversals are allowed before HDF5 assumes it has + found a cycle (previously this defaulted to 16). + The elink_prefix is a filesystem path that is prefixed to the + names of any external link files opened using this LAPL. + -JML 2006/8/23 + - Add H5L link APIs. Old APIs (H5Glink, H5Gmove, etc.) are still + supported but deprecated. + New APIs are: + H5Llink - create a link to an object given its ID + H5Lmove - just like H5Gmove2 + H5Lcopy - copy a link without copying the underlying object + H5Lcreate_hard - like H5Glink2 for hard links + H5Lcreate_soft - like H5Glink2 for soft links + H5Ldelete - just like H5Gunlink + H5Lget_val - just like H5Gget_linkval + H5Lget_info - gets link-specific info (like H5Gget_objinfo) + + In addition, H5Gcreate_anon, H5Tcommit_anon, and H5Dcreate_anon + no longer create links to objects; objects must be manually linked + using H5Llink or they will be deleted when the ID is closed. + + Link Creation Property Lists can be used to pass character + encoding (ASCII or UTF-8) for link names and to set the Intermediate + Group Creation Flag: + H5Pset_char_encoding, H5Pget_char_encoding + H5Pset_copy_object, H5Pget_copy_object + -JML 2006/7/5 + - Added managements of collective IO supports for chunking storage + inside parallel HDF5 + 1) Implemented One IO with collective mode for all chunks in the + application by building one MPI derived datatype accross all + chunks. + 2) Implemented the decision-making support to do collective IO inside + MPI-IO per chunk. + 3) Added the decision-making support to do one IO accross all chunks + or to do multiple IOs with each IO per chunk. + 4) Added the support to handle the case some processes won't do any IOs in + collectively. + 5) Some MPI-IO package(mpich 1.2.6 or lower, e.g.) cannot handle + collective IO correctly for the case when some processes have no + contributions to IOs, a special macro is added to change + collective IO mode to independent IO mode inside HDF5 library. + + Currently we find that MPICH at Linux and vender MPI-IO package at NCSA + Altix cannot handle this case. + + "hdf5_mpi_special_collective_io_works=${hdf5_mpi_special_collective_io_works='no'}" + has been added at the end of file <ia64-linux-gnui> and + <linux-gnulibc1>. + + If MPI-IO packages at your Linux and Altix support this case, + please comment out the last line and report to us at + help@hdfgroup.org. We can tune in our configuration to + support this. + + KY - 2006/02/16 + - Added character encoding to attribute creation property lists. + JML - 2006/01/02 + - Added H5Gcopy() routine to copy objects between while keeping + data in compressed form. QAK - 2005/11/06 + - Added H5Sextent_equal() routine. QAK - 2005/11/06 + - Added HSYS_ERROR which retrieves the system error message and pushes + it to the error stack. This gives more information of the failed + system call. AKC - 2005/08/04 + - Added H5F_OBJ_LOCAL flag to H5Fget_obj_count() & H5Fget_obj_ids(), to + allow querying for objects in file that were opened with a particular + file ID, instead of all objects opened in file with any file ID. + QAK - 2005/06/01 + - Added H5T_CSET_UTF8 character set to mark datatypes that use the + UTF-8 Unicode character encoding. Added tests to ensure that + library handles UTF-8 object names, attributes, etc. -JL 2005/05/13 + - HDF5 supports collective MPI-IO for irregular selection with HDF5 + dataset. Irregular selection is when users use H5Sselect_hyperslab + more than once for the same dataset. + Currently, not all MPI-IO packages support complicated MPI derived + datatype used in the implementation of irregular + selection INSIDE HDF5. + 1) DEC 5.x is not supporting complicated derived datatype. + 2) For AIX 5.1, + if your poe version number is 3.2.0.19 or lower, + please edit powerpc-ibm-aix5.x under hdf5/config, + Find the line with + << hdf5_mpi_complex_derived_datatype_works>> + and UNCOMMENT this line before the configure. + check poe version with the following command: + lpp -l all | grep ppe.poe + 3) For Linux cluster, + if mpich version is 1.2.5 or lower, collective irregular selection + IO is not supported, internally independent IO is used. + 4) For IRIX 6.5, + if C compiler version is 7.3 or lower, collective irregular selection + IO is not supported, internally independent IO is used. + 5) For platforms which internally used mpich, if the + mpich version is 1.2.5 or lower, please find the + corresponding config file and add + hdf5_mpi_complex_derived_datatype_works='no' at the + end of the configuration file. For example, at NCSA + SGI Altix, the internal mpich library is 1.2.5. So + hdf5_mpi_complex_derived_datatype_works='no' should be + added at the end of the config file ia64-linux-gnu. + KY - 2005/09/12 + We also found not all MPI-IO packages support collective IO with one + or more processes to have no contributions to IO. + For mpich version 1.2.6 or lower and all IRIX machine, + if the library checks that there are no IO contributions for some + processes, collective IO request is replaced with + independent inside HDF5. + KY - 2006/05/04 + + - HDF5 N-bit filter + HDF5 support N-bit filter from this version, + The N-Bit filter is used effectively for compressing data of N-Bit + datatype as well as compound and array datatype with N-Bit fields. + KY - 2005/04/15 + - HDF5 scaleoffset filter + HDF5 supports scaleoffset filter for users to do data + compression through HDF5 library. + Scale-Offset compression performs a scale and/or offset operation + on each data value and truncates the resulting value to a minimum + number of bits and then stores the data. + Scaleoffset filter supports floating-point and integer datatype. + Please check the HDF5 reference manual for this. + KY - 2005/06/06 + - Retired SRB vfd (--with-srb). Functions H5Pset_fapl_srb and + H5Pget_fapl_srb were removed. EIP - 2005/04/07 + - Retired GASS vfd (--with-gass). Functions H5Pset_fapl_gass and + H5Pget_fapl_gass are removed too. AKC - 2005/3/3 + - Pablo was removed from the source code EIP - 2005/01/21 + - Modified registration of SZIP to dynamically detect the presence + or absence of the encoder. Changed configure and Makefiles, + and tests to dynamically detect encoder. BEM - 2004/11/02 + - Added function H5Pget_data_transform, together with the previously + added H5Pset_data_transform, to support the data transform + feature. AKC - 2004/10/26 + - Compound datatype has been enhanced with a new feature of size + adjustment. The size can be increased and decreased(without + cutting the last member) as long as it doesn't go down to zero. + No API change is involved. SLU - 2004/10/1 + - Put back 6 old error API functions to be backward compatible with + version 1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, + H5Eset_auto, H5Eget_auto. Their new equivalent functions are + called H5Epush_stack, H5Eprint_stack, H5Ewalk_stack, + H5Eclear_stack, H5Eset_auto_stack, H5Eget_auto_stack. SLU - + 2004/9/2 + - 4 new API functions, H5Tencode, H5Tdecode, H5Sencode, H5Sdecode were + added to the library. Given object ID, these functions encode and + decode HDF5 objects(data type and space) information into and from + binary buffer. SLU - 2004/07/21 + - Modified the way how HDF5 calculates 'pixels_per_scanline' parameter for + SZIP compression. Now there is no restriction on the size and shape of the + chunk except that the total number of elements in the chunk cannot be + bigger than 'pixels_per_block' parameter provided by the user. + EIP - 2004/07/21 + - Added support for SZIP without encoder. Added H5Zget_filter_info + and changed H5Pget_filter and H5Pget_filter_by_id to support this + change. JL/NF - 2004/06/30 + - SZIP always uses K13 compression. This flag no longer needs to + be set when calling H5Pset_szip. If the flag for CHIP + compression is set, it will be ignored (since the two are mutually + exclusive). JL/NF - 2004/6/30 + - A new API function H5Fget_name was added. It returns the name + of the file by object(file, group, data set, named data type, + attribute) ID. SLU - 2004/06/29 + - Added support for user defined identifier types. NF/JL - 2004/06/29 + - A new API function H5Fget_filesize was added. It returns the + actual file size of the opened file. SLU - 2004/06/24 + - New Feature of Data transformation is added. AKC - 2004/05/03. + - New exception handler for datatype conversion is put in to + replace the old overflow callback function. This exception + handler is set through H5Pset_type_conv_cb function. + SLU - 2004/4/27 + - Added option that if $HDF5_DISABLE_VERSION_CHECK is set to 2, + will suppress all library version mismatch warning messages. + AKC - 2004/4/14 + - A new type of dataspace, null dataspace(dataspace without any + element) was added. SLU - 2004/3/24 + - Data type conversion(software) from integer to float was added. + SLU - 2004/3/13 + - Data type conversion(software) from float to integer was added. + Conversion from integer to float will be added later. + SLU -2004/2/4 + - Added new H5Premove_filter routine to remove I/O pipeline filters + from dataset creation property lists. PVN - 2004/01/26 + - Added new 'compare' callback parameter to H5Pregister & H5Pinsert + routines. QAK - 2004/01/07 + - Data type conversion(hardware) between integers and floats was added. + SLU 2003/11/21 + - New function H5Iget_file_id() was added. It returns file ID given + an object(dataset, group, or attribute) ID. SLU 2003/10/29 + - Added new fields to the H5G_stat_t for more information about an + object's object header. QAK 2003/10/06 + - Added new H5Fget_freespace() routine to query the free space in a + given file. QAK 2003/10/06 + - Added backward compatability with v1.6 for new Error API. SLU - + 2003/09/24 + - Changed 'objno' field in H5G_stat_t structure from 'unsigned long[2]' + to 'haddr_t'. QAK - 2003/08/08 + - Changed 'fileno' field in H5G_stat_t structure from 'unsigned long[2]' + to 'unsigned long'. QAK - 2003/08/08 + - Changed 'hobj_ref_t' type from structure with array field to 'haddr_t'. + QAK - 2003/08/08 + - Object references (hobj_ref_t) can now be compared with the 'objno' + field in the H5G_stat_t struct for testing if two objects are the + same within a file. QAK - 2003/08/08 + - Switched over to new error API. SLU - 2003/07/25 + + Parallel Library: + ----------------- + - Added mpich2 as a testing "platform" informally. AKC - 2005/9/28. + - A dataset created in serial mode with H5D_ALLOC_TIME_INCR allocation + setting was not extendible, either explicitly by H5Dextend or + implicitly by writing to unallocated chunks. Library now allocates + more space when needed or directed if the file is opened by parallel + mode, independent of what the dataset allocation mode is. + CC/AKC - 2005/08/29. + - Allow compressed, chunked datasets to be read in parallel. + QAK - 2004/10/04 + - Add options of using atomicity and file-sync to test_mpio_1wMr. + AKC - 2003/11/13 + - Added parallel test, test_mpio_1wMr, which tests if the + underlaying parallel I/O system is conforming to the POSIX + write/read requirement. AKC - 2003/11/12 + + Fortran Library: + ---------------- + - added support for shared Fortran libraries. -JML 2005/09/20 + - added missing h5tget_member_class_f function + EIP 2005/04/06 + - added new functions h5fget_name_f and h5fget_filesize_f + EIP 2004/07/08 + - h5dwrite/read_f and h5awrite/read_f functions only accept dims parameter + of the type INTEGER(HSIZE_T). + - added support for native integers of 8 bytes (i.e. when special + compiler flag is specified to set native fortran integers to 8 bytes, + for example, -i8 flag for PGI and Absoft Fortran compilers, + -qintsize=8 flag for IBM xlf compiler). + EIP 2005/06/20 + - added support for "big" REAL and DOUBLE PRECISION types + (usually the size is specified by compilers flags like + -r8, -r16, etc.) + Known problem: multi file test fails when REAL is 16 bytes. + EIP 2005/09/8 + + C++ Library: + ---------------- + - added support for shared C++ libraries. -JML 2005/09/20 + - Added missing member functions + H5::CompType::getMemberArrayType + H5::CompType::getMemberVarLenType + H5::AbstractDs::getArrayType + H5::AbstractDs::getVarLenType + H5::CommonFG::openArrayType + H5::CommonFG::openVarLenType + H5::PropList::copyProp -- this will replace the current + H5::PropList::copyProp in later releases due + to incorrect prototype. + H5::IdComponent::getHDFObjType + BMR - 2005/08/08 + + + Tools: + ------ + - h5repack and h5diff changed command line parameter syntax to be + similar to h5dump, adding also long switch names. PVN - 2008/1/16 + - h5repack now supports adding multiple filters to all objects. + PVN - 2008/1/16 + - h5dump lists groups and attributes in requested orders (by name and + creation order, both ascending and descending). PVN - 2007/10/5 + - h5import imports string (text) data. PVN - 2007/10/5 + - h52gif and gif2h5: Both these tools were revised to include the High + Level Image API support, and tests were added to /hl/tools/gif2h5. + PVN - 2007/04/13 + - h5dump: added support for double long type H5T_NATIVE_LDOUBLE.

SLU - 2003/10/03 + - Changed output of "OID"s from h5dump from "<number>-<number>" to + "<number". This affects both the "regular" and XML output. + QAK - 2003/08/08 + - Changed output of file IDs and "OID"s from h5ls from + "<number>:<number>:<number>:<number>" to "<number>:<number>" + QAK - 2003/08/08 + + High-Level APIs: + ------ + - Fortran interfaces for the Image, Table and Lite APIs. PVN - 2007/5/1 + - New HDF5 Dimension Scale API (H5DS) allows dimension scales to be + created in an HDF5 file and associated with specific datasets. PVN - 2007/5/1 + - There are two new functions in the Lite library, H5LTtext_to_dtype + and H5LTdtype_to_text. H5LTtext_to_dtype creates a HDF5 data type + given a text description; H5LTdtype_to_text converts a data type + to text description. Only DDL definition is supported as text + desciption now. SLU - 2006/05/17 + - Added Packet Table API for creating tables with less overhead than + H5TB API. Added C++ wrapper for Packet Tables. See documentation. + JML - 2004/03/28 + + Documentation + ------------- + - The documentation for this release is largely complete, but + trails the source code. A few of the newer functions are + not yet documented. FMB - 2007/04/18 + - The user documents for this release can be accessed directly at + this location: + http://www.hdfgroup.uiuc.edu/HDF5/doc_1.8pre/doc/ + The most recent document versions (updated daily) in the + 1.8 development branch can be accessed at this location: + http://www.hdfgroup.uiuc.edu/HDF5/doc_dev_snapshot/H5_dev/ + FMB - 2007/04/18 + + +Support for new platforms, languages and compilers. +======================================= + - Added support for Free-BSD on amd64 with GNU C and Fortran compilers + 4.2.1 + EIP - 2007/06/25 + - Added support for sequential and parallel libraries for Intel 64 Linux + cluster (abe.ncsa.uiuc.edu). Among three MPICH packages available on + this machine, only Open MPI works. The VMI has seg fault in hyperslab.c + and bittests.c tests. The MVAPICH2 complained about mpd not running + the parallel test. (see Known Problems section for more info) + EIP - 2007/06/25 + - Added support for HPUX11.23 for both 32 and 64-bit; HDF5 C++ + - Added support for 64-bit Windows with Visual Studio .NET and 2005. + SJW - 2007/06/25 + - Added suport for HPUX11.23 for both 32 and 64-bit; HDF5 C++ + shared library is not supported with +DD64 flag. + EIP - 2006/06/22 + - Added support for VAX floating numbers for Alpha Open VMS 7.3.2 + EIP - 2006/05/05 + - Fixed broken make.com files in tools directories + EIP - 2006/05/05 + - Added support for Alpha Open VMS 7.3.2 EIP - 2006/04/15 + - Added support for Cray X1. JML - 2005/10/03 + - PGI Fortran compiler is supported on Linux64 systems (x86_64) + EIP - 2004/08/19 + - Absoft compiler f95 v9.0 supported on Linux 2.4 + EIP - 2004/07/29 + - HDF5 Fortran APIs are supported on Mac OSX with IBM XL Fortran + compiler version 8.1. This is a default compiler. + - HDF5 Fortran APIs are supported on MAC OSX with Absoft F95 compiler + version 8.2; set F9X environment varibale to f95, for example + setenv F9X f95 + Use --disable-shared --enable-static configure flags when Absoft + compiler is used. + EIP - 2004/07/27 + - HDF5 Fortran APIs are supported on MAC OSX with IBM XL Fortran + Compiler version 8.1 Use "--disable-shared --enable-static" + configure flags along with the "--enable-fortran" flag to build + Fortran library. EIP - 2004/01/07 + +Bug Fixes since HDF5-1.6.0 release +================================== + + Library + ------- + - Changed library's behavior for reading files that might have + corrupted object header information from a previous (buggy) + version of the library. By default, the library now rebuilds the + correct object header information instead of issuing an error. + Previous "strict" file format interpretation can be enabled with + the "--enable-strict-format-checks" configure option. + QAK - 2008/01/13 + - Fixed several bugs with writing fill values for datasets that have + a variable-length datatype or component datatype. QAK - 2007/06/19 + - STDIO driver didn't support files bigger than 2GB because the OFFSET + parameter of fseek is of type LONG INT, not big enough for big files. + Use fseeko instead for big files if it's available on the system. + SLU - 2007/4/5 + - Fixed a bug in H5Sselect_valid() that caused an incorrect value to + be returned (0) instead of FAIL on error conditions such as the + selection or extent not being defined. CMC - 2007/01/17 + - Fixed the MULTI driver problem (Bug #731) that corruptted the data. + SLU - 2007/1/12 + - Fixed file corruption bug which could write an incorrect number of + messages to an object's header under certain circumstances. + Generally, the sequence of actions to generate this bug looks + like this: + - Create an object + - Close the file + - Re-open the file + - Add 2 (or more) attributes to the object + - Close the file + - Re-open the file + - Delete one of the attributes on the object + - Add a smaller attribute to the object + - Delete the smaller atttribute on the object + - Add a larger attribute on the object + + After this, the number of header messages stored for the object + will be off by one. Other sequences of modifying attributes on an + object could also trigger this bug. If you are opening an + object and the bottom few messages of the HDF5 error stack + resembles this, the object has been affected by this bug: + + #007: ../../hdf5_v1.6/src/H5C.c line 3887 in H5C_load_entry(): unable to load entry + major(08): Meta data cache layer + minor(40): Unable to load metadata into cache + #008: ../../hdf5_v1.6/src/H5Ocache.c line 332 in H5O_load(): corrupt object header - too few messages + major(12): Object header layer + minor(40): Unable to load metadata into cache + + Specifically, "corrupt object header" is the best string to search + for in the HDF5 error stack output. + + If your files have been affected by this bug, or you are concerned + that your files might have been, please contact the HDF Helpdesk + at help@hdfgroup.org for a tool to detect and repair files + affected by this problem. QAK - 2006/6/16 + - Fixed various problems with retrieving names of objects, especially + with mounted files. QAK - 2005/12/25 + - Fixed core dump when closing root groups opened through two different + file handles that operate on the same actual file. QAK - 2005/10/02 + - Corrected errors when performing various operations on a group opened + by dereferencing an object reference. QAK - 2005/07/30 + - Fixed a bug with named datatypes where a copy of a named datatype + used to create a dataset would accidentally use the original + named datatype for the dataset's datatype. QAK - 2005/07/23 + - Made H5Fget_name() be consistent and always return name of actual + file the ID is in. (Instead of the name of the top file in a + file mounting hierarchy). QAK - 2005/07/19 + - Reworked internal file mounting semantics to hopefully eliminate + mounting problems. We now require that files that are mounting + together all have the same "file close degree". QAK - 2005/07/19 + - More bug fixes on holding open files that are mounted and have + IDs open. QAK - 2005/07/14 + - Don't unmount child files until the parent file actually closes. + (Previously, if an object is holding open a file, the child files + would get unmounted too early). QAK - 2005/07/05 + - Fixed bug where unmounted files could cause the library to go into + an infinite loop when shutting down. QAK - 2005/06/30 + - The library didn't save the information of family driver in file. + The original file member size was lost after file was closed (see + bug #213). This has been fixed by saving driver name and member + file size in the superblock. SLU - 2005/6/24 + - Fixed bug with hyperslab selections that use selection offsets and + operate on chunked datasets going into infinite loop or dumping + core. QAK - 2005/06/17 + - Corrected memory leak and possible corruption when opening a group. + QAK - 2005/06/17 + - Added check for opaque datatype tags being too long (check against + H5T_OPAQUE_TAG_MAX, currently set to 256). QAK - 2005/06/14 + - Fixed various errors in maintaining names for open objects in the + face of unusual mount & unmount operations. QAK - 2005/06/08 + - "SEMI" and "STRONG" file close degree settings now apply only to the + particular file ID being closed, instead of operating on all open + file IDs for a given file. QAK - 2005/06/01 + - For family driver, the library didn't save member size in file. + When file is reopened, the size of 1st member file determine the + member size. Now member size is saved in file and is used to + define member file size. Wrong file access property of member size + will result in a failure. Using any other driver except family + will cause library to return error. So is multi driver. SLU - + 2005/05/24 + - Fixed error in opening object in group that was opened in mounted + file which has been unmounted. QAK - 2005/03/17 + - Fixed a racing condition in MPIPOSIX virtual file drive close + function. Now all processes must completed the close before any + of them is returned. This prevents some "faster" processes start + accessing the file for another purpose (e.g., open with truncate) + while other "slower" processes have not closed the same file with + the previous purpose. AKC - 2005/03/01 + - H5Tget_member_value calls for enum datatype didn't return correct + value if H5Tenum_valueof was called first. It's fixed. SLU - + 2005/02/08 + - For variable-length string, H5Tget_class returned H5T_STRING as its + class. But H5Tdetect_class and H5Tget_member_class considered it + as H5T_VLEN. This is fixed to let all these 3 functions treat it + as H5T_STRING. SLU - 2005/02/08 + - The byte order of 1-byte integer types was fixed as little endian + even on a big-endian machine. This has been corrected. SLU - + 2005/02/07 + - Fix segmentation fault when calling H5Fflush with an attribute that + hasn't had a value written to it open. QAK - 2004/10/18 + - Back up supporting bitfield and time types in H5Tget_native_type. + Leave it to future support. The function simply returns error + message of "not support" for bitfield and time types. + SLU - 2004/10/5 + - Fixed address check in Core VFL driver to avoid spurious address/size + overflows for odd valued addresses and/or sizes. QAK - 2004/09/27 + - Fixed parallel bug in which some processes attempted collective + I/O while others did independent I/O. Bug appeared when some + processes used point selections, and others didn't. JRM - 2004/9/15 + - Corrected error where dataset region references were written in an + incorrect way on Cray machines. PVN & QAK - 2004/09/13 + - The H5Tget_native_type now determines the native type for integers + based on the precision. This is to avoid cases of wrongly converting + an int to a short in machines that have a short of 8 bytes but with + 32bit precision (e.g Cray SV1). PVN - 2004/09/07 + - Changed H5Dread() to not overwrite data in an application's buffer + with garbage when accessing a chunked dataset with an undefined + fill value and an unwritten chunk is uncountered. QAK - 2004/08/25 + - Fixed error which could cause a core dump when a type conversion + routine was registered after a compound datatype had been + converted and then an equivalment compound datatype was converted + again. QAK - 2004/08/07 + - Fixed memory overwrite when encoding "multi" file driver information + for file's superblock. QAK - 2004/08/05 + - Fixed obscure bug where a filter which failed during chunk allocation + could allow library to write uncompressed data to disk but think + the data was compressed. QAK - 2004/07/29 + - Fixed bug where I/O to an extendible chunked dataset with zero-sized + dimensions would cause library to fail an assertion. + QAK - 2004/07/27 + - Fixed bug where chunked datasets which have filters defined, + allocation time set to "late" and whose chunks don't align with + the dataspace bounds could have incorrect data stored when + overwriting the entire dataset on the first write. QAK - 2004/07/27 + - Added check to ensure that dataspaces have extents set. JML-2004/07/26 + - Fixed bug on some Solaris systems where HDF5 would try to use + gettimeofday() when that function didn't work properly. + JML - 2004/07/23 + - Fixed bug in H5Sset_extent_simple where setting maximum size to + non-zero, then to zero would cause an error. JML - 2004/07/20 + - Allow NULL pointer for buffer parameter to H5Dread & H5Dwrite + when not writing data ("none" selection or hyperslab or point + selection with no elements defined). QAK - 2004/07/20 + - Calling H5Gcreate() on "/" or "." throws an error instead of + failing quietly. JML - 2004/07/19 + - Fixed bug where setting file address size to be very small could + trigger an assert if the file grew to more than 64 KB. Now throws + an error and data can be recovered. JL/NF - 2004/07/14 + - Fixed bug where "resurrecting" a dataset was failing. + QAK - 2004/07/14 + - Fixed bug where incorrect data could be read from a chunked dataset + after it was extended. QAK - 2004/07/12 + - Fixed failure to read data back from file of compound type with + variable-length string as field. SLU - 2004/06/10 + - Fixed potential file corruption bug when a block of metadata could + overlap the end of the internal metadata accumulator buffer and + the buffer would be extended correctly, but would incorrectly + change it's starting address. QAK - 2004/06/09 + - Opaque datatype with no tag failed for some operations. Fixed. + SLU - 2004/6/3 + - Fixed potential file corruption bug where dimensions that were + too large (a value greater than could be represented in 32-bits) + could cause the incorrect amount of space to be allocated in a + file for the raw data for the dataset. QAK - 2004/06/01 + - Fixed dtypes "sw long double -> double" failure in QSC class + machines. AKC - 2004/4/16 + - Fixed problem with fletcher32 filter when converting data of different + endianess. PVN - 2004/03/10 + - Fixed problem with H5Tget_native_type() not handling opaque fields + correctly. QAK - 2004/01/31 + - Fixed several errors in B-tree deletion code which could cause a + B-tree (used with groups and chunked datasets) to become corrupt + with the right sequence of deleted objects. QAK - 2004/01/19 + - Fixed small internal memory leaks of fill-value information. + QAK - 2004/01/13 + - Fixed bug that caused variable-length datatypes (strings or sequences) + used for datasets in files with objects that were unlinked to + fail to be read/written to a file. QAK - 2004/01/13 + - Detect situation where szip 'pixels per block' is larger than the + fastest changing dimension of a dataset's chunk size and disallow + this (due to limits in szip library). QAK - 2003/12/31 + - Fixed bug with flattened hyperslab selections that would generate + incorrect hyperslab information with certain high-dimensionality + combinations of start/stride/count/block information. + QAK - 2003/12/31 + - Fixed bug with variable-length datatypes used in compound datatypes. + SLU - 2003/12/29 + - Fixed bug in parallel I/O routines that would cause reads from + "short datasets" (datasets which were only partially written out) + to return invalid data. QAK & AKC - 2003/12/19 + - Fixed bug where scalar dataspaces for attributes were reporting as + simple dataspaces. QAK - 2003/12/13 + - Fixed problem with selection offsets of hyperslab selections in + chunked datasets causing the library to go into an infinite loop. + QAK - 2003/12/13 + - Fixed H5Giterate to avoid re-using index parameter after iteration + callback has been called (allows iteration callback to modify the + index parameter itself). QAK - 2003/12/06 + - Fixed various floating-point conversion problems, including a + change which could corrupt data when converting from double->float. + QAK - 2003/11/24 + - Changed "single process" metadata writing in library to collective + I/O by all processes, in order to guarantee correct data being + written with MPI-I/O. QAK - 2003/11/20 + - Fixed problems with fill values and variable-length types and also + I/O on VL values that were set to NULL. QAK - 2003/11/08 + - Fixed problems with MPI datatypes that caused ASCI Q machine to + hang. QAK - 2003/10/28 + - Removed HDF5_MPI_PREFER_DERIVED_TYPES environment variable support, + since it had no benefit. QAK - 2003/10/28 + - Single hyperslab selections (which were set with only one call to + H5Sselect_hyperslab) that had dimensions that could be "flattened" + but were interspersed with dimensions that could not be flattened + were not correctly handled, causing core dumps. QAK - 2003/10/25 + - Fixed incorrect datatype of the third parameter to the Fortran90 + h5pset(get)_cache_f subroutine (INTEGER to INTEGER(SIZE_T)) + EIP - 2003/10/13 + - Fixed problems with accessing variable-length data datatypes on + Crays. QAK - 2003/10/10 + - Fixed potential file corruption bug when too many object header + messages (probably attributes, from a user perspective) were + inserted into an object header and certain other conditions were + met. QAK - 2003/10/08 + - Changed implementation of internal ID searching algorithm to avoid + O(n) behavior for many common cases. QAK - 2003/10/06 + - Allow partial parallel writing to compact datasets. QAK - 2003/10/06 + - Correctly create reference to shared datatype in attribute, instead + of making a copy of the shared datatype in the attribute. + QAK - 2003/10/01 + - Revert changes which caused files >2GB to fail when created with + MPI-I/O file driver on certain platforms. QAK - 2003/09/16 + - Allow compound datatypes to grow in size. SLU - 2003/09/10 + - Detect if a type is already packed before attempting to pack it + again or check if it is locked.

QAK - 2003/09/10 + - Corrected bug in repeated calls to H5Pget_access_plist() which would + incorrectly manage reference counts of internal information and + eventually blow up. QAK - 2003/09/02 + - Return rank of the array datatype on successful call to + H5Tget_array_dims(). QAK - 2003/08/30 + - Corrected bug in H5Tdetect_class which was not correctly detecting + datatype classes of fields in nested compound datatypes in some + circumstances. QAK - 2003/08/30 + - Corrected bug in sieve buffer code which could cause loss of data + when a small dataset was created and deleted in quick succession. + QAK - 2003/08/27 + - Corrected bug in H5Gget_objname_by_idx which was not allowing NULL + for the name when just querying for the object name's length. + QAK - 2003/08/25 + - Corrected bug in variable-length string handling which could + generate a core dump on writing variable-length strings as part + of a compound datatype on certain architectures. QAK - 2003/08/25 + - Corrected bug in H5Tget_native_type which would incorrectly compute + the size of certain compound datatypes and also incorrectly + compute the offset of the last field for those compound datatypes. + QAK - 2003/08/25 + - Corrected bug in H5Tget_native_type which would drop string datatype + metadata (padding, etc.) QAK - 2003/08/25 + - Corrected bugs in H5Gget_num_objs, H5Gget_objname_by_idx and + H5Gget_objtype_by_idx to allow them to accept location IDs, not just + group IDs.

We haven't found these problems on other + MPI-IO compilers. If you encounter these problems, you may use Independent IO + instead. + + Change the following line in your code: + H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE); + + to + H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT); + + KY - 2007/08/24 + +* For SNL, spirit/liberty/thunderbird: The serial tests pass but parallel + tests failed with MPI-IO file locking message. AKC - 2007/6/25. +* On Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers use + -mp -O1 compilation flags to build the libraries. Higher level of optimization + causes failures in several HDF5 library tests. +* For HPUX 11.23 many tools tests failed for 64-bit version when linked to the + shared libraries (tested for 1.8.0-beta2) +* For SNL, Red Storm: only paralle HDF5 is supported. The serial tests pass + and the parallel tests also pass with lots of non-fatal error messages. +* For LLNL, uP: both serial and parallel pass. Zeus: serial passes but + parallel fails with a known proglem in MPI. ubgl: serial passes but + parallel fails. +* on SUN 5.10 C++ test fails in the "Testing Shared Datatypes with Attributes" test +* configuring with --enable-debug=all produces compiler errors on most + platforms. Users who want to run HDF5 in debug mode should use + --enable-debug rather than --enable-debug=all to enable debugging + information on most modules. +* On Mac OS 10.4, test/dt_arith.c has some errors in conversion from long + double to (unsigned) long long and from (unsigned)long long to long double. +* On Altix SGI with Intel 9.0 testmeta.c would not compile with -O3 + optimization flag. +* On VAX, Scaleoffset filter isn't supported. The filter cannot be applied to + HDF5 data generated on VAX. Scaleoffset filter only supports IEEE standard + for floating-point data. +* On Cray X1, a lone colon on the command line of h5dump --xml (as in + the testh5dumpxml.sh script) is misinterpereted by the operating system + and causes an error. +* On mpich 1.2.5 and 1.2.6, we found that if more than two processes + contribute no IO and the application asks to do IO with collective, we found + that when using 4 processors, a simple collective write will be hung + sometimes. This can be verified with t_mpi test under testpar. +* On IRIX6.5, when C compiler version >7.4, the complicate MPI derived data type + code will work. However, the user should be aware to enlarge MPI_TYPE_MAX environment + variable to some certian value in order to use collective irregular selection code. + For example, the current parallel HDF5 test needs to enlarge MPI_TYPE_MAX to + 200,000 to make the test pass. +* The dataset created or rewritten with the v1.6.3 library or after can't + be read with the v1.6.2 library or before when Fletcher32 EDC(filter) is + enabled. There was a bug in the calculating code of the Fletcher32 + checksum in the library before v1.6.3. The checksum value wasn't consistent + between big-endian and little-endian systems. This bug was fixed in + Release 1.6.3. However, after fixing the bug, the checksum value is no + longer the same as before on little-endian system. The library release + after 1.6.4 can still read the dataset created or rewritten with the library + of v1.6.2 or before. SLU - 2005/6/30 +* For the version 6(6.02 and 6.04) of Portland Group compiler on AMD Opteron + processor, there's a bug in the compiler for optimization(-O2). The library + failed in several tests but all related to multi driver. The problem has + been reported to the vendor. +* On IBM AIX systems, parallel HDF5 mode will fail some tests with error + messages like "INFO: 0031-XXX ...". This is from the command poe. + Set the environment variable MP_INFOLEVEL to 0 to minimize the messages + and run the tests again. + The tests may fail with messages like "The socket name is already + in use". HDF5 does not use sockets (except for stream-VFD). This is + due to problems of the poe command trying to set up the debug socket. + Check if there are many old /tmp/s.pedb.* staying around. These are + sockets used by the poe command and left behind due to failed commands. + Ask your system administrator to clean them out. Lastly, request IBM + to provide a mean to run poe without the debug socket. + +* The C++ library's tests fails when compiling with PGI C++ compiler. The + workaround until the problem is correctly handled is to use the + flag "--instantiate=local" prior to the configure and build steps, as: + setenv CXX "pgCC --instantiate=local" for pgCC 5.02 and higher + + +* The stream-vfd test uses ip port 10007 for testing. If another + application is already using that port address, the test will hang + indefinitely and has to be terminated by the kill command. To try the + test again, change the port address in test/stream_test.c to one not + being used in the host. + +* The --enable-static-exec configure flag fails to compile for Solaris + platforms. This is due to the fact that not all of the system + libraries on Solaris are available in a static format. + + The --enable-static-exec configure flag also fails to correctly compile + on IBM SP2 platform for the serial mode. The parallel mode works fine + with this option. + + It is suggested that you don't use this option on these platforms + during configuration. + +* With the gcc 2.95.2 compiler, HDF 5 uses the `-ansi' flag during + compilation. The ANSI version of the compiler complains about not being + able to handle the `long long' datatype with the warning: + + warning: ANSI C does not support `long long' + + This warning is innocuous and can be safely ignored. + + +* The Stream VFD was not tested yet under Windows. It is not supported + in the TFLOPS machine. + + +* The ./dsets tests failed in the TFLOPS machine if the test program, + dsets.c, is compiled with the -O option. The hdf5 library still works + correctly with the -O option. The test program works fine if it is + compiled with -O1 or -O0. Only -O (same as -O2) causes the test + program to fail. + +* Certain platforms give false negatives when testing h5ls: + - Cray J90 and Cray T90IEEE give errors during testing when displaying + some floating-point values. These are benign differences due to + the different precision in the values displayed and h5ls appears to + be dumping floating-point numbers correctly. + +* Before building HDF5 F90 Library from source on Crays + replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src + subdirectory in the top level directory with the Cray-specific files + from this site: + ftp://www.hdfgroup.uiuc.edu/pub/outgoing/hdf5/hdf5-1.8.0-pre/PATCH/ + +* Not all platforms behave correctly with szip's shared libraries. Szip is + disabled in these cases, and a message is relayed at configure time. Static + libraries should be working on all systems that support szip, and should be + used when shared libraries are unavailable. There is also a configure error + on Altix machines that incorrectly reports when a version of szip without + an encoder is being used. + +* On some platforms that use Intel and Absoft compilers to build HDF5 fortran library, + compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90 + complaining about exit subroutine. Comment out the line + IF (total_error .ne. 0) CALL exit (total_error) + +* On IA32 and IA64 systems, if you use a compiler other than GCC (such as + Intel's ecc or icc compilers), you will need to modify the generated + "libtool" program after configuration is finished. On or around line 104 of + the libtool file, there are lines which look like: + + # How to pass a linker flag through the compiler. + wl="" + + change these lines to this: + + # How to pass a linker flag through the compiler. + wl="-Wl," + + UPDATE: This is now done automatically by the configure script. However, if + you still experience a problem, you may want to check this line in the + libtool file and make sure that it has the correct value. + +* Information about building with PGI and Intel compilers is available in + INSTALL file sections 5.7 and 5.8 + +* On at least one system, (SDSC DataStar), the scheduler (in this case + LoadLeveler) sends job status updates to standard error when you run + any executable that was compiled with the parallel compilers. + + This causes problems when running "make check" on parallel builds, as + many of the tool tests function by saving the output from test runs, + and comparing it to an exemplar. + + The best solution is to reconfigure the target system so it no longer + inserts the extra text. However, this may not be practical. + + In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to + the configure and build. This will cause "make check" to continue after + detecting errors in the tool tests. However, in the case of SDSC DataStar, + it also leaves you with some 150 "failed" tests to examine by hand. + + A second solution is to write a script to run serial tests and filter + out the text added by the scheduler. A sample script used on SDSC + DataStar is given below, but you will probably have to customize it + for your installation. + + Observe that the basic idea is to insert the script as the first item + on the command line which executes the the test. The script then + executes the test and filters out the offending text before passing + it on. + + #!/bin/csh + + set STDOUT_FILE=~/bin/serial_filter.stdout + set STDERR_FILE=~/bin/serial_filter.stderr + + rm -f $STDOUT_FILE $STDERR_FILE + + ($* > $STDOUT_FILE) >& $STDERR_FILE + + set RETURN_VALUE=$status + + cat $STDOUT_FILE + + tail +3 $STDERR_FILE + + exit $RETURN_VALUE + + You get the HDF make files and test scipts to execute your filter script + by setting the environment variable "RUNSERIAL" to the full path of the + script prior to running configure for parallel builds. Remember to + "unsetenv RUNSERIAL" before running configure for a serial build. + + Note that the RUNSERIAL environment variable exists so that we can + can prefix serial runs as necessary on the target system. On DataStar, + no prefix is necessary. However on an MPICH system, the prefix might + have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to + get the serial tests to run at all. + + In such cases, you will have to include the regular prefix in your + filter script. + +* H5Ocopy() does not copy reg_ref attributes correctly when shared-message + is turn on. The value of the reference in the destination attriubte is + wrong. This H5Ocopy problem will affect h5copy tool + +%%%%1.6.7%%%% Release Information for hdf5-1.6.7 (31/January/08) + +HDF5 version 1.6.7 released on Thu Jan 31 21:09:10 CST 2008 +================================================================================ + +INTRODUCTION +============ +This document describes the differences between HDF5-1.6.6 and HDF5-1.6.7 +It contains information on the platforms tested and known problems in +HDF5-1.6.7.

Unless otherwise noted, +compilers used are the system compilers. + +Footnotes: +(1) Fortran compiled with g95. + + +Known Problems +============== +* We discovered two problems when running collective IO parallel HDF5 tests + with chunking storage with the ChaMPIon MPI compiler on tungsten, a Linux + cluster at NCSA. + Under some complex selection cases, + 1) MPI_Get_element returns the wrong value. + 2) MPI_Type_struct also generates the wrong derived datatype and corrupt + data may be generated. + This only happens when turning on collective IO with chunking storage + with some complex selections. We haven't found these problems on other + MPI-IO compilers. If you encounter these problems, you may use Independent + IO instead. + + To avoid this problem, change the following line in your code: + H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE); + + to + H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT); + + KY - 2007/08/24 + +* QSC (an HP alpha-based OSF1 cluster) does not create h5pfc correctly. It + does not include the -lmpi properly. This will be fixed in the next + release. AKC - 2007/08/07. + +* On IRIX64 6.5 (UCAR SGI mop1), when testing HDF5 tools with an HDF5 shared + library, especially for h5repacktst and h52gifgentst, the following (or a + similar) error message may appear: + "523648:lt-h5repacktst: rld: Fatal Error: Cannot Successfully map soname + 'libh5test.so.1' under any of the filenames .......(bunch of directories) + " + And the testing will fail. + + We believe this is a libtool problem. One way to get rid of this is to + add the paths of libh5test.so.1 and libh5.so.1 to the shared library path. + + For 32-bit: + You may do this, under csh: + setenv LD_LIBRARYN32_PATH .......(existing paths):[full path of HDF5 + directory/test/.libs]:[full path of HDF5 directory/src/.libs] + + For 64-bit: + setenv LD_LIBRARY64_PATH ......(existing paths):[full path of HDF5 + directory/test/.libs]:[full path of HDF5 directory/src/.libs] + + NOTE: This problem ONLY affects the testing of the HDF5 library when you + build from source. It won't affect any applications that would like to link + with the HDF5 shared library since the shared library path needs to be set + anyway. KY - 2007/8/2 + +* QSC (an HP alpha-based OSF1 cluster) failed the testpar/testphdf5 sub-test + "calloc". All other tests passed. This indicates that a dataset using + chunked storage created by serial HDF5 may not work properly with parallel + HDF5. The calloc test can be skipped by running "prun ... testphdf5 -x + calloc". AKC - 2007/7/12. + +* The Intel C Compiler for the Linux x86_64 platform (EM64T-based, v8.1) has + an optimization error in the datatypes conversion code. Before running + configure, edit the file config/intel-flags by changing the setting of + PROD_CFLAGS from -O3 to -O0. Then run configure. AKC - 2005/11/10. + +* When testing parallel HDF5 with the C compiler version MIPSpro 7.4.3 on IRIX + 6.5, set the environment variable MPI_TYPE_MAX to be a bigger number, for + example 120000, in order to pass the complicated collective IO tests inside + the parallel HDF5 library. This is not a problem inside the parallel HDF5 + library. You can always set a bigger number on your system. KY - 2005/10/6 + +* A contiguous or chunked dataset created by a sequential version of HDF5 + might not be able to be modified with a parallel version of the library. + Use the H5Pset_alloc_time function with H5D_ALLOC_TIME_EARLY to set up the + dataset creation property list to avoid the problem. EIP - 2005/09/09 + +* A dataset created or rewritten with the v1.6.3 library or after can't + be read with the v1.6.2 library or before when Fletcher32 EDC (a filter) is + enabled. There was a bug in the calculating code of the Fletcher32 + checksum in the library before v1.6.3. The checksum value wasn't consistent + between big-endian and little-endian systems. This bug was fixed in + Release 1.6.3. However, after fixing the bug, the checksum value is no + longer the same as before on little-endian system. HDF5 library releases + after 1.6.4 can still read datasets created or rewritten with an HDF5 + library of v1.6.2 or before. SLU - 2005/7/8 + +* For version 6 (6.02 and 6.04) of the Portland Group compiler on AMD Opteron + processor, there's a bug in the compiler for optimization(-O2). The library + failed in several tests, all related to the multi driver. The problem has + been reported to the vendor. + +* test/big fails sometimes with the message "Possible overlap with another + region." The test selects regions randomly, and this error occurs when + two regions overlap each other; it is a bug in the test and not in + HDF5. Since the error is triggered by a random situation, it will + usually disappear if the test is re-run. + +* Newer SGI MIPSpro compilers (version 7.4.x) support C99 features but + have a "guard" statement in stdint.h that will #error and skip the rest + of the header file if the C99 option is not used explicitly. Hardsetting + $CC to c99 will resolve the problem. AKC - 2004/12/13 + +* On IBM AIX systems, parallel HDF5 mode will fail some tests with error + messages like "INFO: 0031-XXX ...". This is from the command poe. + Set the environment variable MP_INFOLEVEL to 0 to minimize the messages + and run the tests again. + + The tests may also fail with messages like "The socket name is already + in use". HDF5 does not use sockets. This is due to problems of the + poe command trying to set up the debug socket. Check whether there are + many old /tmp/s.pedb.* files staying around. These are sockets used by + the poe command and left behind due to failed commands. Ask your system + administrator to clean them out. Lastly, request IBM to provide a means + to run poe without the debug socket. + +* The h5dump tests may fail to match the expected output on some platforms + (e.g. parallel jobs, Windows) where the error messages directed to + "stderr" do not appear in the "right order" with output from stdout. + This is not an error. + +* The --enable-static-exec configure flag fails to compile for Solaris + platforms. This is due to the fact that not all of the system + libraries on Solaris are available in a static format. + + The --enable-static-exec configure flag also fails to correctly compile + on the IBM SP2 platform for the serial mode. The parallel mode works fine + with this option. + + The --enable-static-exec configure flag also fails to correctly compile + on the HPUX 11.00. + + It is suggested that you don't use this option on these platforms + during configuration. + +* Use the --disable-shared configure flag if building with an Absoft Fortran + compiler. + +* Information about building with PGI and Intel compilers is available in + INSTALL file sections 5.7 and 5.8. + +* In LANL QSC, the new cc compiler has problems converting small values of + long long (absolute values less than 1**-308) to double. This triggers + the test/dtypes to report failure in the following test: + Testing random sw long double -> double conversions + If -ieee is used, the converted doubles spread over the range 0.0 to + 10**-308. If -ieee is not used, the converted double values are mostly + 0.0, but occasionally appear as 10**-308. This has been reported to the + system staff. + + All other tests have passed. + +* On at least one system, SDSC DataStar, the scheduler (in this case + LoadLeveler) sends job status updates to standard error when you run + any executable that was compiled with the parallel compilers. + + This causes problems when running "make check" on parallel builds, as + many of the tool tests function by saving the output from test runs, + and comparing it to an exemplar. + + The best solution is to reconfigure the target system so it no longer + inserts the extra text. However, this may not be practical. + + In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to + the configure and build. This will cause "make check" to continue after + detecting errors in the tool tests. However, in the case of SDSC DataStar, + it also leaves you with some 150 "failed" tests to examine by hand. + + A second solution is to write a script to run serial tests and filter + out the text added by the scheduler. A sample script used on SDSC + DataStar is given below, but you will probably have to customize it + for your installation. + + Observe that the basic idea is to insert the script as the first item + on the command line which executes the test. The script then + executes the test and filters out the offending text before passing + it on. + + #!/bin/csh + + set STDOUT_FILE=~/bin/serial_filter.stdout + set STDERR_FILE=~/bin/serial_filter.stderr + + rm -f $STDOUT_FILE $STDERR_FILE + + ($* > $STDOUT_FILE) >& $STDERR_FILE + + set RETURN_VALUE=$status + + cat $STDOUT_FILE + + tail +3 $STDERR_FILE + + exit $RETURN_VALUE + + You get the HDF5 make files and test scripts to execute your filter script + by setting the environment variable "RUNSERIAL" to the full path of the + script prior to running configure for parallel builds. Remember to + "unsetenv RUNSERIAL" before running configure for a serial build. + + Note that the RUNSERIAL environment variable exists so that we can + prefix serial runs as necessary on the target system. On DataStar, + no prefix is necessary. However, on an MPICH system, the prefix might + have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to + get the serial tests to run at all. + + In such cases, you will have to include the regular prefix in your + filter script.

QAK - +2007/06/19 + - STDIO driver didn't support files bigger than 2GB because the OFFSET + parameter of fseek is of type LONG INT, not big enough for big + files. Use fseeko instead for big files if it's available on the + system. SLU - 2007/4/5 + - Relaxed restrictions on attribute operations to allow a file ID to + be used as the "location ID". If a file ID is used, the attribute + operation will occur on the root group of the file. + QAK - 2007/02/09 + - Fixed a bug in H5Sselect_valid() that caused an incorrect value to + be returned (0) instead of FAIL on error conditions such as the + selection or extent not being defined. CMC - 2007/01/05 + - Fixed potential file corruption bug which could overwrite a portion + of an object's header when an attribute was renamed. If the new + name for the attribute was longer than the old name, it was +possible + that the attribute would grow enough to overwrite another message + in the object's header. QAK - 2007/01/02 + - Fixed file corruption bug which could write an incorrect number of + messages to an object's header under certain circumstances. + Generally, the sequence of actions to generate this bug looks + like this: + - Create an object. + - Close the file. + - Re-open the file. + - Add 2 (or more) attributes to the object. + - Close the file. + - Re-open the file. + - Delete one of the attributes on the object. + - Add a smaller attribute to the object. + - Delete the smaller atttribute on the object. + - Add a larger attribute on the object. + + After this, the number of header messages stored for the object + will be off by one. Other sequences of modifying attributes on an + object could also trigger this bug. If you are opening an + object and the bottom few messages of the HDF5 error stack + resembles the following, the object has been affected by this bug: + + #007: ../../hdf5_v1.6/src/H5C.c line 3887 in H5C_load_entry(): +unable to load entry + major(08): Meta data cache layer + minor(40): Unable to load metadata into cache + #008: ../../hdf5_v1.6/src/H5Ocache.c line 332 in H5O_load(): +corrupt object header - too few messages + major(12): Object header layer + minor(40): Unable to load metadata into cache + + Specifically, "corrupt object header" is the best string to search + for in the HDF5 error stack output. + + If your files have been affected by this bug, or you are concerned + that your files might have been, please contact the HDF Helpdesk + at help@hdfgroup.org for a tool to detect and repair files + affected by this problem. QAK - 2006/6/16 + + - Fixed various problems with retrieving names of objects, especially + with mounted files. QAK - 2005/12/25 + + Configuration + ------------- + - Changed to default to --disable-shared if parallel is enabled. + AKC - 2007/5/12 + - Corrected a coding error in configure when it tries to locate the + needed MPI and MPI-IO library for the fortran interface. + AKC - 007/5/9. + - Changed default fortran compiler to g95 when gcc is used. + AKC - 007/2/17. + - Configure can now use any tr command. No more need for + defining the variable TR, nor is it supported. AKC - 2006/05/20 + + Performance + ------------- + - None + + Tools + ----- + - Fixed a bug in h5dump regarding the display of named datatypes + attributes. PVN - 2007/03/13 + - Fixed a bug in h5dump regarding the display of group comments. + PVN - 2007/03/13 + - Fixed a bug in h5dump regarding the display of hardlinks pointing + to the root group. PVN - 2007/03/13 + - Fixed a bug in the h5diff percentage option -p. PVN - 2007/03/05 + - Fixed a bug in h5dump that caused array indices greater than 2^32-1 + not to be printed correctly.

It + does not include the -lmpi properly. This will be fixed in the next + release. AKC - 2007/08/07. + +* On IRIX64 6.5 (UCAR SGI mop1), when testing HDF5 tools with an HDF5 shared + library, especially for h5repacktst and h52gifgentst, the following (or + similar) error message may appear: + "523648:lt-h5repacktst: rld: Fatal Error: Cannot Successfully map soname + 'libh5test.so.1' under any of the filenames .......(bunch of directories) + " + And the testing will fail. + We believe this is a libtool problem. One way to get rid of this is to + add the paths of libh5test.so.1 and libh5.so.1 to the shared library path. + + For 32-bit: + You may do this, under csh: + setenv LD_LIBRARYN32_PATH .......(existing pathes):[full path of HDF5 + directory/test/.libs]:[full path of HDF5 directory/src/.libs] + + For 64-bit: + setenv LD_LIBRARY64_PATH ......(existing pathes):[full path of HDF5 + directory/test/.libs]:[full path of HDF5 directory/src/.libs] + + NOTE: This problem ONLY affects the testing of the HDF5 library when you + build from source. It won't affect any applications that would like to link + with the HDF5 shared library since the shared library path needs to be set + anyway. KY - 2007/8/2 + +* QSC (an HP alpha-based OSF1 cluster) failed the testpar/testphdf5 sub-test + "calloc". All other tests passed. This indicates that a dataset using + chunked storage created by serial HDF5 may not work properly with parallel + HDF5. The calloc test can be skipped by running "prun ... testphdf5 -x + calloc". AKC - 2007/7/12. + +* The Intel C Compiler for the Linux x86_64 platform (EM64T-based, v8.1) has + an optimization error in the datax types conversion code. Before running + configure, edit the file config/intel-flags by changing the setting of + PROD_CFLAGS from -O3 to -O0. Then run configure. AKC - 2005/11/10. + +* When testing parallel HDF5 with the C compiler version MIPSpro 7.4.3 on IRIX + 6.5, set the environment variable MPI_TYPE_MAX to be a bigger number, for + example 120000, in order to pass the complicated collective IO tests inside + the parallel HDF5 library. This is not a problem inside the parallel HDF5 + library. You can always set a bigger number on your system. KY - 2005/10/6 + +* A contiguous or chunked dataset created by a sequential version of HDF5 + might not be able to be modified with a parallel version of the library. + Use the H5Pset_alloc_time function with H5D_ALLOC_TIME_EARLY to set up the + dataset creation property list to avoid the problem. EIP - 2005/09/09 + +* The dataset created or rewritten with the v1.6.3 library or after can't + be read with the v1.6.2 library or before when Fletcher32 EDC (a filter) is + enabled. There was a bug in the calculating code of the Fletcher32 + checksum in the library before v1.6.3. The checksum value wasn't consistent + between big-endian and little-endian systems. This bug was fixed in + Release 1.6.3. However, after fixing the bug, the checksum value is no + longer the same as before on little-endian system. The library release + after 1.6.4 can still read the dataset created or rewritten with the library + of v1.6.2 or before. SLU - 2005/7/8 + +* For version 6 (6.02 and 6.04) of the Portland Group compiler on AMD Opteron + processor, there's a bug in the compiler for optimization(-O2). The library + failed in several tests, all related to the multi driver. The problem has + been reported to the vendor. + +* test/big fails sometimes with the message "Possible overlap with another + region." The test selects regions randomly, and this error occurs when + two regions overlap each other; it is a bug in the test and not in + HDF5. Since the error is triggered by a random situation, it will + usually disappear if the test is re-run. + +* Newer SGI MIPSpro compilers (version 7.4.x) support C99 features but + have a "guard" statement in stdint.h that will #error and skip the rest + of the header file if the C99 option is not used explicitly. Hardsetting + $CC to c99 will resolve the problem. AKC - 2004/12/13 + +* On IBM AIX systems, parallel HDF5 mode will fail some tests with error + messages like "INFO: 0031-XXX ...". This is from the command poe. + Set the environment variable MP_INFOLEVEL to 0 to minimize the messages + and run the tests again. + + The tests may also fail with messages like "The socket name is already + in use". HDF5 does not use sockets (except for stream-VFD). This is + due to problems of the poe command trying to set up the debug socket. + Check whether there are many old /tmp/s.pedb.* files staying around. These + are sockets used by the poe command and left behind due to failed commands. + Ask your system administrator to clean them out. Lastly, request IBM + to provide a means to run poe without the debug socket. + +* The h5dump tests may fail to match the expected output on some platforms + (e.g. parallel jobs, Windows) where the error messages directed to + "stderr" do not appear in the "right order" with output from stdout. + This is not an error. + +* The stream-vfd test uses ip port 10007 for testing. If another + application is already using that port address, the test will hang + indefinitely and has to be terminated by the kill command. To try the + test again, change the port address in test/stream_test.c to one not + being used in the host. + +* The --enable-static-exec configure flag fails to compile for Solaris + platforms. This is due to the fact that not all of the system + libraries on Solaris are available in a static format. + + The --enable-static-exec configure flag also fails to correctly compile + on the IBM SP2 platform for the serial mode. The parallel mode works fine + with this option. + + The --enable-static-exec configure flag also fails to correctly compile + on the HPUX 11.00. + + It is suggested that you don't use this option on these platforms + during configuration. + +* The Stream VFD is not supported under Windows. + +* Use the --disable-shared configure flag if building with Absoft Fortran + compiler. + +* Information about building with PGI and Intel compilers is available in + INSTALL file sections 5.7 and 5.8. + +* In LANL QSC, the new cc compiler has problems converting small values of + long long (absolute values less than 1**-308) to double. This triggers + the test/dtypes to report failure in the following test: + Testing random sw long double -> double conversions + If -ieee is used, the converted doubles spread over the range 0.0 to + 10**-308. If -ieee is not used, the converted double values are mostly + 0.0, but occasionally appear as 10**-308. This has been reported to the + system staff. + + All other tests have passed. + +* On at least one system, SDSC DataStar, the scheduler (in this case + LoadLeveler) sends job status updates to standard error when you run + any executable that was compiled with the parallel compilers. + + This causes problems when running "make check" on parallel builds, as + many of the tool tests function by saving the output from test runs, + and comparing it to an exemplar. + + The best solution is to reconfigure the target system so it no longer + inserts the extra text. However, this may not be practical. + + In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to + the configure and build. This will cause "make check" to continue after + detecting errors in the tool tests. However, in the case of SDSC DataStar, + it also leaves you with some 150 "failed" tests to examine by hand. + + A second solution is to write a script to run serial tests and filter + out the text added by the scheduler. A sample script used on SDSC + DataStar is given below, but you will probably have to customize it + for your installation. + + Observe that the basic idea is to insert the script as the first item + on the command line which executes the test. The script then + executes the test and filters out the offending text before passing + it on. + + #!/bin/csh + + set STDOUT_FILE=~/bin/serial_filter.stdout + set STDERR_FILE=~/bin/serial_filter.stderr + + rm -f $STDOUT_FILE $STDERR_FILE + + ($* > $STDOUT_FILE) >& $STDERR_FILE + + set RETURN_VALUE=$status + + cat $STDOUT_FILE + + tail +3 $STDERR_FILE + + exit $RETURN_VALUE + + You get the HDF5 make files and test scripts to execute your filter script + by setting the environment variable "RUNSERIAL" to the full path of the + script prior to running configure for parallel builds. Remember to + "unsetenv RUNSERIAL" before running configure for a serial build. + + Note that the RUNSERIAL environment variable exists so that we can + prefix serial runs as necessary on the target system. On DataStar, + no prefix is necessary. However, on an MPICH system, the prefix might + have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to + get the serial tests to run at all. + + In such cases, you will have to include the regular prefix in your + filter script.

Old APIs (H5Glink, H5Gmove, etc.) are still - supported but deprecated. - New APIs are: - H5Llink - create a link to an object given its ID - H5Lmove - just like H5Gmove2 - H5Lcopy - copy a link without copying the underlying object - H5Lcreate_hard - like H5Glink2 for hard links - H5Lcreate_soft - like H5Glink2 for soft links - H5Ldelete - just like H5Gunlink - H5Lget_val - just like H5Gget_linkval - H5Lget_info - gets link-specific info (like H5Gget_objinfo) - - In addition, H5Gcreate_anon, H5Tcommit_anon, and H5Dcreate_anon - no longer create links to objects; objects must be manually linked - using H5Llink or they will be deleted when the ID is closed. - - Link Creation Property Lists can be used to pass character - encoding (ASCII or UTF-8) for link names and to set the Intermediate - Group Creation Flag: - H5Pset_char_encoding, H5Pget_char_encoding - H5Pset_copy_object, H5Pget_copy_object - -JML 2006/7/5 - - Added managements of collective IO supports for chunking storage - inside parallel HDF5 - 1) Implemented One IO with collective mode for all chunks in the - application by building one MPI derived datatype accross all - chunks. - 2) Implemented the decision-making support to do collective IO inside - MPI-IO per chunk. - 3) Added the decision-making support to do one IO accross all chunks - or to do multiple IOs with each IO per chunk. - 4) Added the support to handle the case some processes won't do any IOs in - collectively. - 5) Some MPI-IO package(mpich 1.2.6 or lower, e.g.) cannot handle - collective IO correctly for the case when some processes have no - contributions to IOs, a special macro is added to change - collective IO mode to independent IO mode inside HDF5 library. - - Currently we find that MPICH at Linux and vender MPI-IO package at NCSA - Altix cannot handle this case. - - "hdf5_mpi_special_collective_io_works=${hdf5_mpi_special_collective_io_works='no'}" - has been added at the end of file <ia64-linux-gnui> and - <linux-gnulibc1>. - - If MPI-IO packages at your Linux and Altix support this case, - please comment out the last line and report to us at - help@hdfgroup.org. We can tune in our configuration to - support this. - - KY - 2006/02/16 - - Added character encoding to attribute creation property lists. - JML - 2006/01/02 - - Added H5Gcopy() routine to copy objects between while keeping - data in compressed form. QAK - 2005/11/06 - - Added H5Sextent_equal() routine. QAK - 2005/11/06 - - Added HSYS_ERROR which retrieves the system error message and pushes - it to the error stack. This gives more information of the failed - system call. AKC - 2005/08/04 - - Added H5F_OBJ_LOCAL flag to H5Fget_obj_count() & H5Fget_obj_ids(), to - allow querying for objects in file that were opened with a particular - file ID, instead of all objects opened in file with any file ID. - QAK - 2005/06/01 - - Added H5T_CSET_UTF8 character set to mark datatypes that use the - UTF-8 Unicode character encoding. Added tests to ensure that - library handles UTF-8 object names, attributes, etc. -JL 2005/05/13 - - HDF5 supports collective MPI-IO for irregular selection with HDF5 - dataset. Irregular selection is when users use H5Sselect_hyperslab - more than once for the same dataset. - Currently, not all MPI-IO packages support complicated MPI derived - datatype used in the implementation of irregular - selection INSIDE HDF5. - 1) DEC 5.x is not supporting complicated derived datatype. - 2) For AIX 5.1, - if your poe version number is 3.2.0.19 or lower, - please edit powerpc-ibm-aix5.x under hdf5/config, - Find the line with - << hdf5_mpi_complex_derived_datatype_works>> - and UNCOMMENT this line before the configure. - check poe version with the following command: - lpp -l all | grep ppe.poe - 3) For Linux cluster, - if mpich version is 1.2.5 or lower, collective irregular selection - IO is not supported, internally independent IO is used. - 4) For IRIX 6.5, - if C compiler version is 7.3 or lower, collective irregular selection - IO is not supported, internally independent IO is used. - 5) For platforms which internally used mpich, if the - mpich version is 1.2.5 or lower, please find the - corresponding config file and add - hdf5_mpi_complex_derived_datatype_works='no' at the - end of the configuration file. For example, at NCSA - SGI Altix, the internal mpich library is 1.2.5. So - hdf5_mpi_complex_derived_datatype_works='no' should be - added at the end of the config file ia64-linux-gnu. - KY - 2005/09/12 - We also found not all MPI-IO packages support collective IO with one - or more processes to have no contributions to IO. - For mpich version 1.2.6 or lower and all IRIX machine, - if the library checks that there are no IO contributions for some - processes, collective IO request is replaced with - independent inside HDF5. - KY - 2006/05/04 - - - HDF5 N-bit filter - HDF5 support N-bit filter from this version, - The N-Bit filter is used effectively for compressing data of N-Bit - datatype as well as compound and array datatype with N-Bit fields. - KY - 2005/04/15 - - HDF5 scaleoffset filter - HDF5 supports scaleoffset filter for users to do data - compression through HDF5 library. - Scale-Offset compression performs a scale and/or offset operation - on each data value and truncates the resulting value to a minimum - number of bits and then stores the data. - Scaleoffset filter supports floating-point and integer datatype. - Please check the HDF5 reference manual for this. - KY - 2005/06/06 - - Retired SRB vfd (--with-srb). Functions H5Pset_fapl_srb and - H5Pget_fapl_srb were removed. EIP - 2005/04/07 - - Retired GASS vfd (--with-gass). Functions H5Pset_fapl_gass and - H5Pget_fapl_gass are removed too. AKC - 2005/3/3 - - Pablo was removed from the source code EIP - 2005/01/21 - - Modified registration of SZIP to dynamically detect the presence - or absence of the encoder. Changed configure and Makefiles, - and tests to dynamically detect encoder. BEM - 2004/11/02 - - Added function H5Pget_data_transform, together with the previously - added H5Pset_data_transform, to support the data transform - feature. AKC - 2004/10/26 - - Compound datatype has been enhanced with a new feature of size - adjustment. The size can be increased and decreased(without - cutting the last member) as long as it doesn't go down to zero. - No API change is involved. SLU - 2004/10/1 - - Put back 6 old error API functions to be backward compatible with - version 1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, - H5Eset_auto, H5Eget_auto. Their new equivalent functions are - called H5Epush_stack, H5Eprint_stack, H5Ewalk_stack, - H5Eclear_stack, H5Eset_auto_stack, H5Eget_auto_stack. SLU - - 2004/9/2 - - 4 new API functions, H5Tencode, H5Tdecode, H5Sencode, H5Sdecode were - added to the library. Given object ID, these functions encode and - decode HDF5 objects(data type and space) information into and from - binary buffer. SLU - 2004/07/21 - - Modified the way how HDF5 calculates 'pixels_per_scanline' parameter for - SZIP compression. Now there is no restriction on the size and shape of the - chunk except that the total number of elements in the chunk cannot be - bigger than 'pixels_per_block' parameter provided by the user. - EIP - 2004/07/21 - - Added support for SZIP without encoder. Added H5Zget_filter_info - and changed H5Pget_filter and H5Pget_filter_by_id to support this - change. JL/NF - 2004/06/30 - - SZIP always uses K13 compression. This flag no longer needs to - be set when calling H5Pset_szip. If the flag for CHIP - compression is set, it will be ignored (since the two are mutually - exclusive). JL/NF - 2004/6/30 - - A new API function H5Fget_name was added. It returns the name - of the file by object(file, group, data set, named data type, - attribute) ID. SLU - 2004/06/29 - - Added support for user defined identifier types. NF/JL - 2004/06/29 - - A new API function H5Fget_filesize was added. It returns the - actual file size of the opened file. SLU - 2004/06/24 - - New Feature of Data transformation is added. AKC - 2004/05/03. - - New exception handler for datatype conversion is put in to - replace the old overflow callback function. This exception - handler is set through H5Pset_type_conv_cb function. - SLU - 2004/4/27 - - Added option that if $HDF5_DISABLE_VERSION_CHECK is set to 2, - will suppress all library version mismatch warning messages. - AKC - 2004/4/14 - - A new type of dataspace, null dataspace(dataspace without any - element) was added. SLU - 2004/3/24 - - Data type conversion(software) from integer to float was added. - SLU - 2004/3/13 - - Data type conversion(software) from float to integer was added. - Conversion from integer to float will be added later. - SLU -2004/2/4 - - Added new H5Premove_filter routine to remove I/O pipeline filters - from dataset creation property lists. PVN - 2004/01/26 - - Added new 'compare' callback parameter to H5Pregister & H5Pinsert - routines. QAK - 2004/01/07 - - Data type conversion(hardware) between integers and floats was added. - SLU 2003/11/21 - - New function H5Iget_file_id() was added. It returns file ID given - an object(dataset, group, or attribute) ID. SLU 2003/10/29 - - Added new fields to the H5G_stat_t for more information about an - object's object header. QAK 2003/10/06 - - Added new H5Fget_freespace() routine to query the free space in a - given file. QAK 2003/10/06 - - Added backward compatability with v1.6 for new Error API. SLU - - 2003/09/24 - - Changed 'objno' field in H5G_stat_t structure from 'unsigned long[2]' - to 'haddr_t'. QAK - 2003/08/08 - - Changed 'fileno' field in H5G_stat_t structure from 'unsigned long[2]' - to 'unsigned long'. QAK - 2003/08/08 - - Changed 'hobj_ref_t' type from structure with array field to 'haddr_t'. - QAK - 2003/08/08 - - Object references (hobj_ref_t) can now be compared with the 'objno' - field in the H5G_stat_t struct for testing if two objects are the - same within a file. QAK - 2003/08/08 - - Switched over to new error API. SLU - 2003/07/25 Parallel Library: ----------------- - - Added mpich2 as a testing "platform" informally. AKC - 2005/9/28. - - A dataset created in serial mode with H5D_ALLOC_TIME_INCR allocation - setting was not extendible, either explicitly by H5Dextend or - implicitly by writing to unallocated chunks. Library now allocates - more space when needed or directed if the file is opened by parallel - mode, independent of what the dataset allocation mode is. - CC/AKC - 2005/08/29. - - Allow compressed, chunked datasets to be read in parallel. - QAK - 2004/10/04 - - Add options of using atomicity and file-sync to test_mpio_1wMr. - AKC - 2003/11/13 - - Added parallel test, test_mpio_1wMr, which tests if the - underlaying parallel I/O system is conforming to the POSIX - write/read requirement.

QAK - 2007/02/14 - - Added new tool, h5copy. PVN - 2006/7/15 - - Removed obsolete pdb2hdf5 tool from tools/misc -JML 2005/10/24 - - Added build_h5perf_alone.sh that builds h5perf by standalone mode. - AKC - 2005/09/18. - - Sped up h5dump on files with large numbers of objects. - QAK - 2005/08/25 - - Added a standalone mode for building h5perf. AKC - 2005/08/12 - - new tool, h5jam. See reference manual. 2004/10/08 - - h5repack.sh did not report errors encountered during tests. It does - now. AKC - 2004/04/02 - - Added the MPI-I/O and MPI-POSIX drivers to the list of VFL drivers - available for h5dump and h5ls. RPM & QAK - 2004/02/01 - - Added option --vfd= to h5ls to allow a VFL driver to be selected - by a user. RPM & QAK - 2004/02/01 - - Added option -showconfig to compiler tools (h5cc,h5fc,h5c++). - AKC - 2004/01/08 - - Install the "h5cc" and "h5fc" tools as "h5pcc" and "h5pfc" - respectively if library is built in parallel mode. - WCW - 2003/11/04 - - Added metadata benchmark (perform/perf_meta).

PVN - 2007/5/1 - - New HDF5 Dimension Scale API (H5DS) allows dimension scales to be - created in an HDF5 file and associated with specific datasets. PVN - 2007/5/1 - - There are two new functions in the Lite library, H5LTtext_to_dtype - and H5LTdtype_to_text. H5LTtext_to_dtype creates a HDF5 data type - given a text description; H5LTdtype_to_text converts a data type - to text description. Only DDL definition is supported as text - desciption now. SLU - 2006/05/17 - - Added Packet Table API for creating tables with less overhead than - H5TB API. Added C++ wrapper for Packet Tables. See documentation. - JML - 2004/03/28 Documentation ------------- - - The documentation for this release is largely complete, but - trails the source code. A few of the newer functions are - not yet documented. FMB - 2007/04/18 - - The user documents for this beta can be accessed directly at - this location: - http://www.hdfgroup.uiuc.edu/HDF5/doc_1.8pre/doc/ - The most recent document versions (updated daily) in the - 1.8 development branch can be accessed at this location: - http://www.hdfgroup.uiuc.edu/HDF5/doc_dev_snapshot/H5_dev/ - FMB - 2007/04/18 - Support for new platforms, languages and compilers. ======================================= - - Added support for Free-BSD on amd64 with GNU C and Fortran compilers - 4.2.1 - EIP - 2007/06/25 - - Added support for sequential and parallel libraries for Intel 64 Linux - cluster (abe.ncsa.uiuc.edu). Among three MPICH packages available on - this machine, only Open MPI works. The VMI has seg fault in hyperslab.c - and bittests.c tests. The MVAPICH2 complained about mpd not running - the parallel test. (see Known Problems section for more info) - EIP - 2007/06/25 - - Added support for HPUX11.23 for both 32 and 64-bit; HDF5 C++ - - Added support for 64-bit Windows with Visual Studio .NET and 2005. - SJW - 2007/06/25 - - Added suport for HPUX11.23 for both 32 and 64-bit; HDF5 C++ - shared library is not supported with +DD64 flag. - EIP - 2006/06/22 - - Added support for VAX floating numbers for Alpha Open VMS 7.3.2 - EIP - 2006/05/05 - - Fixed broken make.com files in tools directories - EIP - 2006/05/05 - - Added support for Alpha Open VMS 7.3.2 EIP - 2006/04/15 - - Added support for Cray X1. JML - 2005/10/03 - - PGI Fortran compiler is supported on Linux64 systems (x86_64) - EIP - 2004/08/19 - - Absoft compiler f95 v9.0 supported on Linux 2.4 - EIP - 2004/07/29 - - HDF5 Fortran APIs are supported on Mac OSX with IBM XL Fortran - compiler version 8.1. This is a default compiler. - - HDF5 Fortran APIs are supported on MAC OSX with Absoft F95 compiler - version 8.2; set F9X environment varibale to f95, for example - setenv F9X f95 - Use --disable-shared --enable-static configure flags when Absoft - compiler is used. - EIP - 2004/07/27 - - HDF5 Fortran APIs are supported on MAC OSX with IBM XL Fortran - Compiler version 8.1 Use "--disable-shared --enable-static" - configure flags along with the "--enable-fortran" flag to build - Fortran library. EIP - 2004/01/07 - -Bug Fixes since HDF5-1.6.0 release + +Bug Fixes since HDF5-1.8.0 release ================================== Library ------- - - Fixed several bugs with writing fill values for datasets that have - a variable-length datatype or component datatype. QAK - 2007/06/19 - - STDIO driver didn't support files bigger than 2GB because the OFFSET - parameter of fseek is of type LONG INT, not big enough for big files. - Use fseeko instead for big files if it's available on the system. - SLU - 2007/4/5 - - Fixed a bug in H5Sselect_valid() that caused an incorrect value to - be returned (0) instead of FAIL on error conditions such as the - selection or extent not being defined. CMC - 2007/01/17 - - Fixed the MULTI driver problem (Bug #731) that corruptted the data. - SLU - 2007/1/12 - - Fixed file corruption bug which could write an incorrect number of - messages to an object's header under certain circumstances. - Generally, the sequence of actions to generate this bug looks - like this: - - Create an object - - Close the file - - Re-open the file - - Add 2 (or more) attributes to the object - - Close the file - - Re-open the file - - Delete one of the attributes on the object - - Add a smaller attribute to the object - - Delete the smaller atttribute on the object - - Add a larger attribute on the object - - After this, the number of header messages stored for the object - will be off by one. Other sequences of modifying attributes on an - object could also trigger this bug. If you are opening an - object and the bottom few messages of the HDF5 error stack - resembles this, the object has been affected by this bug: - - #007: ../../hdf5_v1.6/src/H5C.c line 3887 in H5C_load_entry(): unable to load entry - major(08): Meta data cache layer - minor(40): Unable to load metadata into cache - #008: ../../hdf5_v1.6/src/H5Ocache.c line 332 in H5O_load(): corrupt object header - too few messages - major(12): Object header layer - minor(40): Unable to load metadata into cache - - Specifically, "corrupt object header" is the best string to search - for in the HDF5 error stack output. - - If your files have been affected by this bug, or you are concerned - that your files might have been, please contact the HDF Helpdesk - at help@hdfgroup.org for a tool to detect and repair files - affected by this problem. QAK - 2006/6/16 - - Fixed various problems with retrieving names of objects, especially - with mounted files. QAK - 2005/12/25 - - Fixed core dump when closing root groups opened through two different - file handles that operate on the same actual file. QAK - 2005/10/02 - - Corrected errors when performing various operations on a group opened - by dereferencing an object reference. QAK - 2005/07/30 - - Fixed a bug with named datatypes where a copy of a named datatype - used to create a dataset would accidentally use the original - named datatype for the dataset's datatype. QAK - 2005/07/23 - - Made H5Fget_name() be consistent and always return name of actual - file the ID is in. (Instead of the name of the top file in a - file mounting hierarchy). QAK - 2005/07/19 - - Reworked internal file mounting semantics to hopefully eliminate - mounting problems. We now require that files that are mounting - together all have the same "file close degree". QAK - 2005/07/19 - - More bug fixes on holding open files that are mounted and have - IDs open. QAK - 2005/07/14 - - Don't unmount child files until the parent file actually closes. - (Previously, if an object is holding open a file, the child files - would get unmounted too early). QAK - 2005/07/05 - - Fixed bug where unmounted files could cause the library to go into - an infinite loop when shutting down. QAK - 2005/06/30 - - The library didn't save the information of family driver in file. - The original file member size was lost after file was closed (see - bug #213). This has been fixed by saving driver name and member - file size in the superblock. SLU - 2005/6/24 - - Fixed bug with hyperslab selections that use selection offsets and - operate on chunked datasets going into infinite loop or dumping - core. QAK - 2005/06/17 - - Corrected memory leak and possible corruption when opening a group. - QAK - 2005/06/17 - - Added check for opaque datatype tags being too long (check against - H5T_OPAQUE_TAG_MAX, currently set to 256). QAK - 2005/06/14 - - Fixed various errors in maintaining names for open objects in the - face of unusual mount & unmount operations. QAK - 2005/06/08 - - "SEMI" and "STRONG" file close degree settings now apply only to the - particular file ID being closed, instead of operating on all open - file IDs for a given file. QAK - 2005/06/01 - - For family driver, the library didn't save member size in file. - When file is reopened, the size of 1st member file determine the - member size. Now member size is saved in file and is used to - define member file size. Wrong file access property of member size - will result in a failure. Using any other driver except family - will cause library to return error. So is multi driver. SLU - - 2005/05/24 - - Fixed error in opening object in group that was opened in mounted - file which has been unmounted. QAK - 2005/03/17 - - Fixed a racing condition in MPIPOSIX virtual file drive close - function. Now all processes must completed the close before any - of them is returned. This prevents some "faster" processes start - accessing the file for another purpose (e.g., open with truncate) - while other "slower" processes have not closed the same file with - the previous purpose. AKC - 2005/03/01 - - H5Tget_member_value calls for enum datatype didn't return correct - value if H5Tenum_valueof was called first. It's fixed. SLU - - 2005/02/08 - - For variable-length string, H5Tget_class returned H5T_STRING as its - class. But H5Tdetect_class and H5Tget_member_class considered it - as H5T_VLEN. This is fixed to let all these 3 functions treat it - as H5T_STRING. SLU - 2005/02/08 - - The byte order of 1-byte integer types was fixed as little endian - even on a big-endian machine. This has been corrected. SLU - - 2005/02/07 - - Fix segmentation fault when calling H5Fflush with an attribute that - hasn't had a value written to it open. QAK - 2004/10/18 - - Back up supporting bitfield and time types in H5Tget_native_type. - Leave it to future support. The function simply returns error - message of "not support" for bitfield and time types. - SLU - 2004/10/5 - - Fixed address check in Core VFL driver to avoid spurious address/size - overflows for odd valued addresses and/or sizes.
