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.

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.

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.

Support ***************************************************************************** 1. Obtaining HDF5 - The latest supported public release of HDF5 is available from - ftp://ftp.hdfgroup.org/HDF5/current/src. For Unix and UNIX-like - platforms, it is available in tar format compressed with gzip. - For Microsoft Windows, it is in ZIP format. - - The HDF team also makes snapshots of the source code available on - a regular basis. These snapshots are unsupported (that is, the - HDF team will not release a bug-fix on a particular snapshot; - rather any bug fixes will be rolled into the next snapshot). - Furthermore, the snapshots have only been tested on a few - machines and may not test correctly for parallel applications. - Snapshots, in a limited number of formats, can be found on THG's - development FTP server: - - ftp://ftp.hdfgroup.uiuc.edu/pub/outgoing/hdf5/snapshots - - -2. Quick installation - For those who don't like to read ;-) the following steps can be used - to configure, build, test, and install the HDF5 Library, header files, - and support programs. For example, to install HDF5 version X.Y.Z at - location /usr/local/hdf5, use the following steps. - - $ gunzip < hdf5-X.Y.Z.tar.gz | tar xf - - $ cd hdf5-X.Y.Z - $ ./configure --prefix=/usr/local/hdf5 <more configure_flags> - $ make - $ make check # run test suite. - $ make install - $ make check-install # verify installation. - - Some versions of the tar command support the -z option. In such cases, - the first step above can be simplified to the following: - - $ tar zxf hdf5-X.Y.Z.tar.gz - - <configure_flags> above refers to the configure flags appropriate - to your installation. For example, to install HDF5 with the - Fortran and C++ interfaces and with SZIP compression, the - configure line might read as follows: - - $ ./configure --prefix=/usr/local/hdf5 --enable-fortran \ - --enable-cxx --with-szlib=PATH_TO_SZIP - - In this case, PATH_TO_SZIP would be replaced with the path to the - installed location of the SZIP library. - -2.1. Windows - Users of Microsoft Windows should see the INSTALL_Windows files for - detailed instructions. - -2.2. RedStorm (Cray XT3) - Users of the Red Storm machine, after reading this file, should read - the Red Storm section in the INSTALL_parallel file for specific - instructions for the Red Storm machine. The same instructions would - probably work for other Cray XT3 systems, but they have not been - verified. - - -3. HDF5 dependencies -3.1. Zlib - The HDF5 Library includes a predefined compression filter that - uses the "deflate" method for chunked datasets. If zlib-1.1.2 or - later is found, HDF5 will use it. Otherwise, HDF5's predefined - compression method will degenerate to a no-op; the compression - filter will succeed but the data will not be compressed. - -3.2. Szip (optional) - The HDF5 Library includes a predefined compression filter that - uses the extended-Rice lossless compression algorithm for chunked - datasets. For more information about Szip compression and license - terms, see http://hdfgroup.org/doc_resource/SZIP/. - - Precompiled Szip binaries for each supported platform and a source - tar file can be found at ftp://ftp.hdfgroup.org/lib-external/szip/. - - To configure the HDF5 Library with the Szip compression filter, use - the '--enable-szlib=/PATH_TO_SZIP' flag. For more information, see - section 4.3.7, "Specifying other libraries and headers." - - Starting with release 1.6.3, Szip library binaries are distributed - with the encoder enabled (a license may be required to use this binary) - and with the encoder disabled (freely usable without a license). - If the encoder enabled binary is used, Szip compression encoding is - available for an HDF5 application; if the encoder disabled binary is - used, Szip compression is not available. Szip decoding is always - available for applications (i.e., an HDF5 application can always read - Szip-compressed data) if the Szip filter is present, regardless of the - binary used. - -3.3. MPI and MPI-IO - The parallel version of the library is built upon the foundation - provided by MPI and MPI-IO. If these libraries are not available - when HDF5 is configured, only a serial version of HDF5 can be built. - - -4. Full installation instructions for source distributions - -4.1. Unpacking the distribution - The HDF5 source code is distributed in a variety of formats which - can be unpacked with the following commands, each of which creates an - 'hdf5-X.Y.Z' directory, where X.Y.Z is the HDF5 version numbers. - -4.1.1. Non-compressed tar archive (*.tar) - - $ tar xf hdf5-X.Y.Z.tar - -4.1.2. Compressed tar archive (*.tar.Z) - - $ uncompress -c < hdf5-X.Y.Z.tar.Z | tar xf - - Or - $ tar Zxf hdf5-X.Y.Z.tar.Z - -4.1.3. Gzip'd tar archive (*.tar.gz) - - $ gunzip < hdf5-X.Y.Z.tar.gz | tar xf - - Or - $ tar zxf hdf5-X.Y.Z.tar.gz - -4.1.4. Bzip'd tar archive (*.tar.bz2) - - $ bunzip2 < hdf5-X.Y.Z.tar.bz2 | tar xf - - Or - $ tar jxf hdf5-X.Y.Z.tar.bz2 - -4.2. Source versus build directories - On most systems the build can occur in a directory other than the - source directory, allowing multiple concurrent builds and/or - read-only source code. In order to accomplish this, one should - create a build directory, cd into that directory, and run the - `configure' script found in the source directory (configure - details are below). For example, - $ mkdir built-fortran - $ cd build-fortran - $ ../hdf5-X.Y.Z/configure --enable-fortran ... - - Unfortunately, this does not work on recent Irix platforms (6.5? - and later) because that `make' does not understand the VPATH variable. - However, HDF5 also supports Irix `pmake' which has a .PATH target - which serves a similar purpose. Here's what the Irix man pages say - about VPATH, the facility used by HDF5 makefiles for this feature: - - The VPATH facility is a derivation of the undocumented - VPATH feature in the System V Release 3 version of make. - System V Release 4 has a new VPATH implementation, much - like the pmake(1) .PATH feature. This new feature is also - undocumented in the standard System V Release 4 manual - pages. For this reason it is not available in the IRIX - version of make. The VPATH facility should not be used - with the new parallel make option. - -4.3. Configuring - HDF5 uses the GNU autoconf system for configuration, which - detects various features of the host system and creates the - Makefiles. On most systems it should be sufficient to say: - - $ ./configure - Or - $ sh configure - - The configuration process can be controlled through environment - variables, command-line switches, and host configuration files. - For a complete list of switches type: - - $ ./configure --help - - The host configuration files are located in the `config' - directory and are based on architecture name, vendor name, and/or - operating system which are displayed near the beginning of the - `configure' output. The host config file influences the behavior - of configure by setting or augmenting shell variables. - -4.3.1. Specifying the installation directories - The default installation location is the HDF5 directory created in - the build directory. Typing `make install' will install the HDF5 - Library, header files, examples, and support programs in hdf5/lib, - hdf5/include, hdf5/doc/hdf5/examples, and hdf5/bin. To use a path - other than hdf5, specify the path with the `--prefix=PATH' switch: - - $ ./configure --prefix=/usr/local - - If shared libraries are being built (the default), the final - home of the shared library must be specified with this switch - before the library and executables are built. - - HDF5 can be installed into a different location than the prefix - specified at configure time; see section 4.6, "Installing HDF5," - for more details. - -4.3.2. Using an alternate C compiler - By default, configure will look for the C compiler by trying - `gcc' and `cc'. However, if the environment variable "CC" is set - then its value is used as the C compiler. For instance, one would - use the following line to specify the native C compiler on a system - that also has the GNU gcc compiler (users of csh and derivatives - will need to prefix the commands below with `env'): - - $ CC=cc ./configure - - A parallel version of HDF5 can be built by specifying `mpicc' - as the C compiler. (The `--enable-parallel' flag documented - below is optional in this case.) Using the `mpicc' compiler - will insure that the correct MPI and MPI-IO header files and - libraries are used. - - $ CC=/usr/local/mpi/bin/mpicc ./configure - -4.3.3. Configuring for 64-bit support - Several machine architectures support 32-bit or 64-bit binaries. - The options below describe how to enable support for different options. - - On Irix64, the default compiler is `cc'. To use an alternate compiler, - specify it with the CC variable: - - $ CC='cc -n32' ./configure - - Similarly, users compiling on a Solaris machine and desiring to - build the distribution with 64-bit support should specify the - correct flags with the CC variable: - - $ CC='cc -xarch=v9' ./configure - - To configure AIX 64-bit support including the Fortran and C++ APIs, - (Note: need to set $AR to 'ar -X 64'.) - Serial: - $ CFLAGS=-q64 FFLAGS=-q64 CXXFLAGS=-q64 AR='ar -X 64'\ - ./configure --enable-fortran - Parallel: (C++ not supported with parallel) - $ CFLAGS=-q64 FFLAGS=-q64 AR='ar -X 64'\ - ./configure --enable-fortran - -4.3.4. Additional compilation flags - If addtional flags must be passed to the compilation commands, - specify those flags with the CFLAGS variable. For instance, - to enable symbolic debugging of a production version of HDF5, one - might say: - - $ CFLAGS=-g ./configure --enable-production - -4.3.5. Compiling HDF5 wrapper libraries - One can optionally build the Fortran and/or C++ interfaces to the - HDF5 C library. By default, both options are disabled. To build - them, specify `--enable-fortran' and `--enable-cxx', respectively. - - $ ./configure --enable-fortran - $ ./configure --enable-cxx - - Configuration will halt if a working Fortran 90 or 95 compiler or - C++ compiler is not found. Currently, the Fortran configure tests - for these compilers in order: f90, pgf90, f95. To use an - alternate compiler specify it with the FC variable: - - $ FC=/usr/local/bin/g95 ./configure --enable-fortran - - Note: The Fortran and C++ interfaces are not supported on all the - platforms the main HDF5 Library supports. Also, the Fortran - interface supports parallel HDF5 while the C++ interface does - not. - - Note: See sections 4.7 and 4.8 for building the Fortran library with - Intel or PGI compilers. - -4.3.6. Specifying other programs - The build system has been tuned for use with GNU make but also - works with other versions of make. If the `make' command runs a - non-GNU version but a GNU version is available under a different - name (perhaps `gmake'), then HDF5 can be configured to use it by - setting the MAKE variable. Note that whatever value is used for - MAKE must also be used as the make command when building the - library: - - $ MAKE=gmake ./configure - $ gmake - - The `AR' and `RANLIB' variables can also be set to the names of - the `ar' and `ranlib' (or `:') commands to override values - detected by configure. - - The HDF5 Library, include files, and utilities are installed - during `make install' (described below) with a BSD-compatible - install program detected automatically by configure. If none is - found, the shell script bin/install-sh is used. Configure does not - check that the install script actually works; if a bad install is - detected on your system (e.g., on the ASCI blue machine as of - March 2, 1999) you have two choices: - - 1. Copy the bin/install-sh program to your $HOME/bin - directory, name it `install', and make sure that $HOME/bin - is searched before the system bin directories. - - 2. Specify the full path name of the `install-sh' program - as the value of the INSTALL environment variable. Note: do - not use `cp' or some other program in place of install - because the HDF5 makefiles also use the install program to - change file ownership and/or access permissions. - -4.3.7. Specifying other libraries and headers - Configure searches the standard places (those places known by the - systems compiler) for include files and header files. However, - additional directories can be specified by using the CPPFLAGS - and/or LDFLAGS variables: - - $ CPPFLAGS=-I/home/robb/include \ + The latest supported public release of HDF5 is available from + ftp://hdf.ncsa.uiuc.edu/HDF5/current/src. For Unix platforms, it is + available in tar format compressed with gzip. For Microsoft Windows, + it is in ZIP format. + + The HDF team also makes snapshots of the source code available on + a regular basis. These snapshots are unsupported (that is, the + HDF team will not release a bug-fix on a particular snapshot; + rather any bug fixes will be rolled into the next snapshot). + Furthermore, the snapshots have only been tested on a few + machines and may not test correctly for parallel applications. + Snapshots can be found at + ftp://hdf.ncsa.uiuc.edu/pub/outgoing/hdf5/snapshots in a limited + number of formats. + + +2. Warnings about compilers + OUTPUT FROM THE FOLLOWING COMPILERS SHOULD BE EXTREMELY SUSPECT + WHEN USED TO COMPILE THE HDF5 LIBRARY, ESPECIALLY IF + OPTIMIZATIONS ARE ENABLED. IN ALL CASES, HDF5 ATTEMPTS TO WORK + AROUND THE COMPILER BUGS BUT THE HDF5 DEVELOPMENT TEAM MAKES NO + GUARANTEES THAT THERE ARE OTHER CODE GENERATION PROBLEMS. + +2.1. GNU (Intel platforms) + Versions before 2.8.1 have serious problems allocating registers + when functions contain operations on `long long' data types. + Supplying the `--disable-hsizet' switch to configure (documented + below) will prevent hdf5 from using `long long' data types in + situations that are known not to work, but it limits the hdf5 + address space to 2GB. + +2.2. COMPAQ/DEC + The V5.2-038 compiler (and possibly others) occasionally + generates incorrect code for memcpy() calls when optimizations + are enabled, resulting in unaligned access faults. HDF5 works + around the problem by casting the second argument to `char *'. + The fortran module (5.4.1a) fails in compiling some fortran + programs. Need to use 5.5.0 or more. + +2.3. SGI (Irix64 6.2) + The Mongoose 7.00 compiler has serious optimization bugs and + should be upgraded to MIPSpro 7.2.1.2m. Patches are available + from SGI. + +2.4. Windows/NT + The MicroSoft Win32 5.0 compiler is unable to cast unsigned long + long values to doubles. HDF5 works around this bug by first + casting to signed long long and then to double. + + A link warning: defaultlib "LIBC" conflicts with use of other libs + appears for debug version of VC++ 6.0. This warning will not affect + building and testing hdf5 libraries. + + +3. Quick installation + For those that don't like to read ;-) the following steps can be + used to configure, build, test, and install the HDF5 library, + header files, and support programs. + + $ gunzip < hdf5-1.6.0.tar.gz | tar xf - + $ cd hdf5-1.6.0 + $ make check + $ make install + +3.1. Windows + Users of Microsoft Windows should see the INSTALL_Windows for + detailed instructions. + +3.2.

The same instructions would + probably work for other Cray XT3 systems but they have not been + verified. + + +4. HDF5 dependencies +4.1. Zlib + The HDF5 library has a predefined compression filter that uses + the "deflate" method for chunked datatsets. If zlib-1.1.2 or + later is found then HDF5 will use it, otherwise HDF5's predefined + compression method will degenerate to a no-op (the compression + filter will succeed but the data will not be compressed). + +4.2. Szip + The HDF5 library has a predefined compression filter that uses + the extended-Rice lossless compression algorithm for chunked + datatsets. For more information about Szip compression and license terms + see http://hdf.ncsa.uiuc.edu/HDF5/doc_resource/SZIP/index.html. + Precompiled szip binaries for each supported platform and source tar ball + file can be found at ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/ + +4.3. MPI and MPI-IO + The parallel version of the library is built upon the foundation + provided by MPI and MPI-IO.

Optimization versus symbolic debugging - The library can be compiled to provide symbolic debugging support - so it can be debugged with gdb, dbx, ddd, etc., or it can be - compiled with various optimizations. To compile for symbolic - debugging (the default for snapshots), say `--disable-production'; - to compile with optimizations (the default for supported public - releases), say `--enable-production'.

Parallel versus serial library - The HDF5 Library can be configured to use MPI and MPI-IO for - parallelism on a distributed multi-processor system. Read the - file INSTALL_parallel for detailed explanations. - -4.3.11. Threadsafe capability - The HDF5 Library can be configured to be thread-safe (on a very - large scale) with the `--enable-threadsafe' flag to the configure - script. Some platforms may also require the '-with-pthread=INC,LIB' - (or '--with-pthread=DIR') flag to the configure script. - For further details, see "HDF5 Thread Safe Library": - - http://www.hdfgroup.org/HDF5/doc/TechNotes/ThreadSafeLibrary.html - -4.3.12. Backward compatibility - The 1.8 version of the HDF5 Library can be configured to operate - identically to the v1.6 library with the - --with-default-api-version=v16 - configure flag. This allows existing code to be compiled with the - v1.8 library without requiring immediate changes to the application - source code. For addtional configuration options and other details, - see "API Compatibility Macros in HDF5": - - http://www.hdfgroup.org/HDF5/doc/RM/APICompatMacros.html - -4.4. Building - The library, confidence tests, and programs can be built by - saying just: - - $ make - - Note that if you have supplied some other make command via the MAKE - variable during the configuration step, that same command must be - used here. - - When using GNU make, you can add `-j -l6' to the make command to - compile in parallel on SMP machines. Do not give a number after - the `-j' since GNU make will turn it off for recursive invocations - of make. - - $ make -j -l6 - -4.5. Testing - HDF5 comes with various test suites, all of which can be run by - saying - - $ make check - - To run only the tests for the library, change to the `test' - directory before issuing the command. Similarly, tests for the - parallel aspects of the library are in `testpar' and tests for - the support programs are in `tools'. - - The `check' consists of two sub-tests, check-s and check-p, which - are for serial and parallel tests, respectively. Since serial tests - and parallel tests must be run with single and multiple processes - respectively, the two sub-tests work nicely for batch systems in - which the number of processes is fixed per batch job. One may submit - one batch job, requesting 1 process, to run all the serial tests by - "make check-s"; and submit another batch job, requesting multiple - processes, to run all the parallel tests by "make check-p". - - Temporary files will be deleted by each test when it completes, - but may continue to exist in an incomplete state if the test - fails. To prevent deletion of the files, define the HDF5_NOCLEANUP - environment variable. - - The HDF5 tests can take a long time to run on some systems. To perform - a faster (but less thorough) test, set the HDF5TestExpress environment - variable to 2 or 3 (with 3 being the shortest run). To perform a - longer test, set HDF5TestExpress to 0. 1 is the default. - -4.6. Installing HDF5 - The HDF5 Library, include files, and support programs can be - installed in a (semi-)public place by saying `make install'. The - files are installed under the directory specified with - `--prefix=DIR' (default is 'hdf5') in directories named `lib', - `include', and `bin'. The directories, if not existing, will be - created automatically, provided the mkdir command supports the -p - option. - - If `make install' fails because the install command at your site - somehow fails, you may use the install-sh that comes with the - source.

Large (>2GB) vs. small (<2GB) file capability + In order to read or write files that could potentially be larger + than 2GB it is necessary to use the non-ANSI `long long' data + type on some platforms. However, some compilers (e.g., GNU gcc + versions before 2.8.1 on Intel platforms) are unable to produce + correct machine code for this data type. To disable use of the + `long long' type on these machines say: + + $ ./configure --disable-hsizet + +5.3.11. Parallel vs. serial library + The HDF5 library can be configured to use MPI and MPI-IO for + parallelizm on a distributed multi-processor system. Read the + file INSTALL_parallel for detailed explanations. + +5.3.12. Threadsafe capability + The HDF5 library can be configured to be thread-safe (on a very + large scale) with the with the `--enable-threadsafe' flag to + the configure script. Some platforms may also require the + '-with-pthread=INC,LIB' (or '--with-pthread=DIR') flag to the configure + script as well. Read the file doc/TechNotes/ThreadSafeLibrary.html + for further details. + +5.3.13. Backward compatibility + The 1.8 version of the HDF5 library can be configured to operate + identically to the v1.6 library with the `--enable-hdf5v1_6' + configure flag. This allows existing code to be compiled with the + v1.8 library without requiring immediate changes to the + application source code. This flag will only be supported in the + v1.8 branch of the library, it will not be available in v1.9+. + +5.3.14. Network stream capability + The HDF5 library can be configured with a network stream file + driver with the `--enable-stream-vfd' configure flag. This option + compiles the "stream" Virtual File Driver into the main library. + See the documentation on the Virtual File Layer for more details + about the use of this driver. The network stream capability is + enabled by default, except for use in parallel or with a parallel + compiler, where it is disabled. Explicitly enabling Stream-VFD + will allow for its use in parallel. + +5.4. Building + The library, confidence tests, and programs can be build by + saying just: + + $ make + + Note that if you supplied some other make command via the MAKE + variable during the configuration step then that same command + must be used here. + + When using GNU make you can add `-j -l6' to the make command to + compile in parallel on SMP machines. Do not give a number after + th `-j' since GNU make will turn it off for recursive invocations + of make. + + $ make -j -l6 + +5.5. Testing + HDF5 comes with various test suites, all of which can be run by + saying + + $ make check + + To run only the tests for the library change to the `test' + directory before issuing the command. Similarly, tests for the + parallel aspects of the library are in `testpar' and tests for + the support programs are in `tools'. + + Temporary files will be deleted by each test when it complets, + but may continue to exist in an incomplete state if the test + fails. To prevent deletion of the files define the HDF5_NOCLEANUP + environment variable. + + The HDF5 tests can take a long time to run on some systems. To + perform a faster (but less thorough) test, set the HDF5TestExpress + environment variable to 2 or 3 (with 3 being the shortest run). + To perform a longer test, set HDF5TestExpress to 0. 1 is the default. + +5.6. Installing + The HDF5 library, include files, and support programs can be + installed in a (semi-)public place by saying `make install'. The + files are installed under the directory specified with + `--prefix=DIR' (or '/usr/local') in directories named `lib', + `include', and `bin'. The prefix directory must exist prior to + `make install', but its subdirectories are created automatically. + + If `make install' fails because the install command at your site + somehow fails, you may use the install-sh that comes with the + source. You need to run ./configure again. $ INSTALL="$PWD/bin/install-sh -c" ./configure ... $ make install - If you want to install HDF5 in a location other than the location - specified by the `--prefix=DIR' flag during configuration (or - instead of the default location, `hdf5'), you can do that - by running the deploy script: + If you want to install HDF5 in a location other than the location + specified by the `--prefix=DIR' flag during configuration (or + instead of the default location, `/usr/local'), you can do that + by running the deploy script: $ bin/deploy NEW_DIR - This will install HDF5 in NEW_DIR.

COMPAQ/DEC - The V5.2-038 compiler (and possibly others) occasionally - generates incorrect code for memcpy() calls when optimizations - are enabled, resulting in unaligned access faults. HDF5 works - around the problem by casting the second argument to `char *'. - The Fortran module (5.4.1a) fails in compiling some Fortran - programs. Use 5.5.0 or higher. - -A.3. SGI (Irix64 6.2) - The Mongoose 7.00 compiler has serious optimization bugs and - should be upgraded to MIPSpro 7.2.1.2m. Patches are available - from SGI. - -A.4. Windows/NT - The Microsoft Win32 5.0 compiler is unable to cast unsigned long - long values to doubles. HDF5 works around this bug by first - casting to signed long long and then to double. - - A link warning: defaultlib "LIBC" conflicts with use of other libs - appears for debug version of VC++ 6.0.

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 - 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.

EIP - 2004/01/07 + +Bug Fixes since HDF5-1.6.0 release ================================== Library ------- - - Fixed the problem with the searching of target file for H5Lcreate_external(). - The searching pattern will depend on whether the target file's - pathname is an absolute or a relative path. Please see the description - in the RM for H5Lcreate_external(). (VC - 4/8/08) - - Fixed possible file corruption bug when encoding datatype - descriptions for compound datatypes whose size was between - 256 & 511 bytes and the file was opened with the "use the - latest format" property enabled (with H5Pset_libver_bounds). - (QAK - 2008/03/13) - - Fixed bug in H5Aget_num_attrs() routine to handle invalid location - ID correctly. (QAK - 2008/03/11) - + - 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. SLU - 2003/09/10 + - Corrected bug when opening a file twice with read-only permission + for one open and then closing the read-only access file ID would + generate an error. 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. QAK - 2003/08/21 + - Corrected bug when using scalar dataspace for memory selection and + operating on chunked dataset. QAK - 2003/08/18 + - Corrected bugs with multiple '/' characters in names for H5Glink + and H5Gunlink. QAK - 2003/08/16 + - Corrected bug with user blocks that didn't allow a user block to + be inserted in front of a file after the file was created. + QAK - 2003/08/13 + - Corrected errors with using point selections to access data in + chunked datasets. QAK - 2003/07/23 + - Corrected error with variable-length datatypes and chunked datasets + caused H5Dwrite to fail sometimes.

AKC - 2003/07/22 Performance ------------- + - Optimized I/O for enumerated datatypes that are a superset of source + enumerated datatype. QAK - 2005/03/19 + - More optimizations to inner loops of datatype conversions for + integers and floats which give a 10-50% speedup. QAK - 2003/11/07 + - Hoisted invariant 'if/else's out of inner datatype conversion loop for + integer and floating-point values, giving about a 20% speedup. + QAK - 2003/10/20 Tools ----- - - Fixed bug in h5diff that prevented datasets & attributes with - variable-length string elements from comparing correctly. - (QAK - 2008/02/28) - - h5import bug on Windows w/binary datasets. fread in windows needs a - binary file to be open with 'rb' instead of 'r' otherwise it - terminates execution if an end of file character is found on the - input file. Besides that the binary file generated needs to be open - with 'wb' , otherwise an end of line character is read twice. - (PVN - 2008/02/19) - - Fixed bug in h5dump that caused binary output to be made only for the first - dataset, when several datasets were requested. (PVN - 2008/04/07) - + - Fixed h5dump regarding the display of blocks in hyperslab + selections. PVN 2008/01/16 + - Fixed h5diff regarding the display of NaN (Not a Number) + values.
