To override this and view actual compile and + link lines during building, the --disable-silent-rules flag can be used + at configure time, or the 'make' command can be followed by V=1, to + indicate a "verbose" make. (MAM - 2011/4/14). + - Added mpicc and mpif90 as the default C and Fortran compilers for Linux + systems when --enable-parallel is specified but no $CC or $FC is defined. + (AKC - 2011/2/7) + - Added a new configure option, "--enable-unsupported", which can + be used to stop configure from preventing the use of unsupported + configure option combinations, such as c++ in parallel or Fortran + with threadsafe. Use at your own risk, as it may result in a + library that won't compile or run as expected! + (MAM - 2010/11/17 - Bug 2061) + + Library + ------- + - The library allows the dimension size of a dataspace to be zero. In + the past, the library would allow this only if the maximal dimension + size was unlimited. Now there is no such restriction, but no data + can be written to this kind of dataset. (SLU - 2011/4/20) + - We added two new macros, H5_VERSION_GE and H5_VERSION_LE, to let users + compare certain version numbers with the library being used. (SLU - + 2011/4/20) + - Added ability to cache files opened through external links. Added new + public functions H5Pset_elink_file_cache_size(), + H5Pget_elink_file_cache_size(), and H5Fclear_elink_file_cache(). + (NAF - 2011/02/17) + - Finished implementing all options for 'log' VFD. (QAK - 2011/1/25) + - Removed all old code for Metrowerks compilers, bracketed by + __MWERKS__). Metrowerks compiler is long gone. (AKC - 2010/11/17) + + Parallel Library + ---------------- + - None + + Tools + ----- + - h5diff: Added new "verbose with levels" option, '-vN, --verbose=N'. + The old '-v, --verbose' option is deprecated but remains available; + it is exactly equivalent to '-v0, --verbose=0'. + The new levels 1 ('-v1' or '--verbose=1') and 2 ('-v2' or + '--verbose=2') can be specified to view more information regarding + attributes differences. Bug #2121 (JKM 2011/3/23) + - h5dump: Added new option --enable-error-stack. This option will + display error stack information in the output stream. This is + useful when the "h5dump: Unable to print data" message is output. + (ADB - 2011/03/03) + + High-Level APIs + --------------- + - Fortran LT make datasets routines (H5LTmake_dataset_f, + h5ltmake_dataset_int_f, h5ltmake_dataset_float_f, h5ltmake_dataset_double_f) + and LT read datasets routines (h5ltread_dataset_f,h5ltread_dataset_int_f, + h5ltread_dataset_float_f, 5ltread_dataset_double_f) can now handle + 4-dimensional to 7-dimensional rank datasets. HDFFV-1217 (MSB-2011/4/24/2011) + + F90 API + ------- + - None + + C++ API + ------- + - None + + +Support for New Platforms, Languages, and Compilers +=================================================== + - Intel V11.1 uses now -O3 optimization in production mode (EIP - 2010/10/08) + + + +Bug Fixes since HDF5-1.8.6 +========================== + + Configuration + ------------- + - Shared C++ and HL libraries on AIX should now be working correctly. + Note that Fortran shared libraries are still not working on AIX. + (See the Known Problems section, below). (MAM - 2011/4/20) + - Removed config/ibm-aix6.x. All IBM-AIX settings are in one file, + ibm-aix. (AKC - 2011/4/14) + - Shared C libraries are no longer disabled on Mac when Fortran + is enabled. Shared Fortran libraries are still not supported on Mac, + so configure will disable them by default, but this is overrideable + with the new --enable-unsupported configure option. The configure + summary has been updated to reflect the fact that the shared-ness of + the C++/Fortran wrapper libraries may not align with the C library. + (MAM - 2011/04/11 - HDFFV-4353). + + Library + ------- + - Changed assertion failure when decoding a compound datatype with no + fields into a normal error failure. Also prohibit using this sort + of datatype for creating an attribute (as is already the case for + datasets and committed (named) datatypes). (QAK - 2011/04/15, Jira + issue #HDFFV-2766) + - Tell the VFL flush call that the file will be closing, allowing + the VFDs to avoid sync'ing the file (particularly valuable in parallel). + (QAK - 2011/03/09) + - The datatype handler created with H5Tencode/decode used to have the + reference count 0 (zero); it now has the reference count 1 (one). + (SLU - 2011/2/18) + - Fixed the definition of H5_HAVE_GETTIMEOFDAY on Windows so that + HDgettimeofday() is defined and works properly. Bug HDFFV-5931 + (DER - 2011/04/14) + - Added basic VFD tests for the Windows, STDIO and log VFD tests. + (DER - 2011/04/11) + + Parallel Library + ---------------- + - None + + Tools + ----- + - Updated h5dump test case script to prevent entire test failure when + source directory is read-only. Bug #HDFFV-4342 (JKM 2011/4/12) + - Fixed h5dump displaying incorrect values for H5T_STD_I8BE type data in + attribute on Big-Endian machine. H5T_STD_I8BE is unsigned 8bit type, + so h5dump is supposed to display -2 instead of 254. It worked correctly + on Little-Endian system , but not on Big-Endian system. Bug #HDFFV-4358 + (JKM 04/08/2011) + - Updated some HDF5 tools to standardize the option name as + '--enable-error-stack' for printing HDF5 error stack messages. h5ls and + h5dump have been updated. For h5ls, this replaces "-e/--errors" option, + which is deprecated. For h5dump, this is a new option. Bug #2182 + (JKM 2011/3/30) + - Fixed the h5diff --use-system-epsilon option. The formula used in the + calculation was changed from ( |a - b| / b ) to ( |a - b| ). + This was done to improve performance. Bug #2184 (JKM 2011/3/24) + - Fixed output for H5T_REFERENCE in h5dump. According to the BNF document + the output of a H5T_REFERENCE should be followed by the type; + <reference> ::= H5T_REFERENCE { <ref_type> } + <ref_type> ::= H5T_STD_REF_OBJECT | H5T_STD_REF_DSETREG + Previously this was only displayed if the -R option was used. + Bug #1725 (ADB 2011/3/28) + - Fixed two h5diff issues. 1) h5diff compared attributes correctly only + when two objects had the same number of attributes and the attribute + names were identical. 2) h5diff did not display useful information about + attribute differences. Bug #2121 (JKM 2011/3/17) + - Fixed a memory leak in h5diff that occurred when accessing symbolic links + with the --follow-symlink option. Bug #2214 (JKM 2011/3/18) + - Fixed a memory leak in h5diff that occurred when accessing variable length + string data. Bug #2216 (JKM 2011/3/18) + - Fixed and improved the help page for h5ls -a, --address option. + Bug #1904 (JKM 2011/3/11) + - Fixed h5copy to enable copying an object into the same HDF5 file. + Previously h5copy displayed an error message when the target file + was the same as the source file. (XCAO 2011/3/8) + - Fixed an h5dump problem that caused the tool to skip some data elements + in large datasets with a large array datatype on Windows. This issue + arose only on Windows due to the different return behavior of the + _vsnprintf() function. Bug #2161 (JKM 2011/3/3) + - Fixed h5dump which was skipping some array indices in large datasets + with a relatively large array datatype. The interval of skipped indices + varied according to the size of the array. Bug #2092 (JKM 2011/2/15) + - Fixed h5diff which was segfaulting when comparing compound datasets + with a combination of fixed-length string datatypes and variable-length + string datatypes in certain orders. Bug #2089 (JKM 2010/12/28) + - Improved h5diff performance. 1) Now use HDmemcmp() before comparing two + elements. 2) Replace expensive H5Tequals() calls. 3) Retrieve datatype + information at dataset level, not at each element level for compound + datasets. HDFFV-7516 (JKM 2011/4/18) + - Fixed h5ls to display nested compound types with curly brackets + when -S (--simple) option is used with -l (--label), so it shows + which members (in curly brackets) belong to which nested compound type, + making the output clearer. Bug #1979 (JKM 2010/11/09) + - Fixed h5diff to handle variable-length strings in a compound dataset + and variable-length string arrays in a compound dataset correctly. + Garbage values were previously displayed when h5diff compared multiple + variable-length strings in a compound type dataset. + Bug #1989 (JKM 2010/10/28) + - Fixed h5copy to fail gracefully when copying an object to a non- + existing group without the -p option. Bug #2040 (JKM 2010/10/18) + + F90 API + ------ + - None + + C++ API + ------ + - None + + High-Level APIs: + ------ + - None + + Fortran High-Level APIs: + ------ + - h5tbmake_table_f: Fixed error in passing an array of characters with different + length field names. + - h5tget_field_info_f: Fixed error with packing the C strings into a Fortran + array of strings. Added optional argument called 'maxlen_out' which returns + the maximum string character length in a field name element. + Bug HDFFV-1255 (MSB- 4/17/2011) + + + + +Platforms Tested +================ +The following platforms and compilers have been tested for this release. + + AIX 6.1 xlc 11.1.0.3 + (NCSA BP) xlC 11.1.0.3 + xlf90 13.1.0.3 + mpcc_r 11.1.0.3 + mpxlf90_r 13.1.0.3 + + FreeBSD 8.2-STABLE i386 gcc 4.2.1 [FreeBSD] 20070719 + (loyalty) g++ 4.2.1 [FreeBSD] 20070719 + gcc 4.6.1 20110422 + g++ 4.6.1 20110422 + gfortran 4.6.1 20110422 + + FreeBSD 8.2-STABLE amd64 gcc 4.2.1 [FreeBSD] 20070719 + (freedom) g++ 4.2.1 [FreeBSD] 20070719 + gcc 4.6.1 20110422 + g++ 4.6.1 20110422 + gfortran 4.6.1 20110422 + + Linux 2.6.18-194.3.1.el5PAE gcc (GCC) 4.1.2 and 4.4.2 + #1 SMP i686 i686 i386 G95 (GCC 4.0.3 (g95 0.93!)

support was fixed for some bugs, it was discovered + that "make prefix=XXX install" no longer works for shared libraries. It + still works correctly for static libraries. Therefore, if you want to + install the HDF5 shared libraries in a location such as /usr/local/hdf5, + you need to specify the location via the --prefix option during configure + time. E.g, ./configure --prefix=/usr/local/hdf5 ... + (AKC - 2011/05/07 HDFFV-7583) + +* The parallel test, t_shapesame, in testpar/, may run for a long time and may + be terminated by the alarm signal. If that happens, one can increase the + alarm seconds (default is 1200 seconds = 20 minutes) by setting the + environment variable, $HDF5_ALARM_SECONDS, to a larger value such as 3600 + (60 minutes). Note that the t_shapesame test may fail in some systems + (see the "While working on the 1.8.6 release..." problem below). If + it does, it will waste more time if $HDF5_ALARM_SECONDS is set + to a larger value. (AKC - 2011/05/07) + +* The C++ and FORTRAN bindings are not currently working on FreeBSD. + (QAK - 2011/04/26) + +* Shared Fortran libraries are not quite working on AIX. While they are + generated when --enable-shared is specified, the fortran and hl/fortran + tests fail. We are looking into the issue. HL and C++ shared libraries + should now be working as intended, however. (MAM - 2011/04/20) + +* The --with-mpe configure option does not work with Mpich2. AKC - 2011/03/10 + +* If parallel gmake (e.g., gmake -j 4) is used, the "gmake clean" command + sometimes fails in the perform directory due to the attempt to remove the + executable of h5perf or h5perf_serial by two "parallel" commands. This error + has no consequence on the functionality of the HDF5 library or install. It + is fixed in the next release. AKC - 2011/01/25 + +* While working on the 1.8.6 release of HDF5, a bug was discovered that can + occur when reading from a dataset in parallel shortly after it has been + written to collectively. The issue was exposed by a new test in the parallel + HDF5 test suite, but had existed before that. We believe the problem lies with + certain MPI implementations and/or file systems. + + We have provided a pure MPI test program, as well as a standalone HDF5 + program, that can be used to determine if this is an issue on your system. + They should be run across multiple nodes with a varying number of processes. + These programs can be found at: + http://www.hdfgroup.org/ftp/HDF5/examples/known_problems/ + +* The library's test dt_arith.c showed a compiler's rounding problem on + Cygwin when converting from unsigned long long to long double. The + library's own conversion works fine. We defined a macro for Cygwin to + skip this test until we can solve the problem. Please see bug #1813. + SLU - 2010/5/5 + +* All the VFL drivers aren't backward compatible. In H5FDpublic.h, the + structure H5FD_class_t changed in 1.8. There is new parameter added to + get_eoa and set_eoa callback functions. A new callback function + get_type_map was added in. The public function H5FDrealloc was taken + out in 1.8. The problem only happens when users define their own driver + for 1.6 and try to plug in 1.8 library. Because there's only one user + complaining about it, we (Elena, Quincey, and I) decided to leave it as + it is (see bug report #1279). Quincey will make a plan for 1.10. + SLU - 2010/2/2 + +* MinGW has a missing libstdc++.dll.a library file and will not successfully link + C++ applications/tests. Do not use the enable-cxx configure option. Read all of + the INSTALL_MINGW.txt file for all restrictions. ADB - 2009/11/11 + +* The PathScale MPI implementation, accessing a Panasas file system, would + cause H5Fcreate() with H5F_ACC_EXCL to fail even when the file does not + exist. This is due to the MPI_File_open() call failing if the mode has + the MPI_MODE_EXCL bit set. (See bug 1468 for details.) AKC - 2009/8/11 + +* Parallel tests failed with 16 processes with data inconsistency at testphdf5 + / dataset_readAll. Parallel tests also failed with 32 and 64 processes with + collective abort of all ranks at t_posix_compliant / allwrite_allread_blocks + with MPI IO. CMC - 2009/04/28 + +* For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh and + tools/h5copy/testh5copy.sh will fail some of its sub-tests. These sub-tests + are expected to fail and should exit with a non-zero code but the yod + command does not propagate the exit code of the executables. Yod always + returns 0 if it can launch the executable. The test suite shell expects + a non-zero for this particular test, therefore it concludes the test has + failed when it receives 0 from yod. Skip all the "failing" test for now + by changing them as following. + + ======== Original tools/h5ls/testh5ls.sh ========= + TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 + ======== Change to =============================== + echo SKIP TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 + ================================================== + + ======== Original tools/h5copy/testh5copy.sh ========= + TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename + TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets + TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets + TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested + H5LSTEST $FILEOUT + ======== Change to =============================== + echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename + echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets + echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets + echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested + echo SKIP H5LSTEST $FILEOUT + ================================================== + AKC - 2008/11/10 + +* For Red Storm, a Cray XT3 system, the yod command sometimes gives the + message, "yod allocation delayed for node recovery". This interferes with + test suites that do not expect to see this message. See the section of "Red + Storm" in file INSTALL_parallel for a way to deal with this problem. + AKC - 2008/05/28 + +* On an Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers, + use -mp -O1 compilation flags to build the libraries. A higher level of + optimization causes failures in several HDF5 library tests. + +* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and + the application asks to do collective IO, we have found that when using 4 + processors, a simple collective write will sometimes be hung. This can be + verified with t_mpi test under testpar. + +* A dataset created or rewritten with a v1.6.3 library or after cannot be read + with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled. + There was a bug in the calculation of the Fletcher32 checksum in the + library before v1.6.3; the checksum value was not 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 was no longer the same as + before on little-endian system. Library releases after 1.6.4 can still read + datasets created or rewritten with an HDF5 library of v1.6.2 or before. + SLU - 2005/6/30 + +* 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", + but HDF5 does not use sockets. This failure is due to problems with the + poe command trying to set up the debug socket. To resolve this problem, + check to see 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. First, ask your system administrator to clean them out. + Lastly, request IBM to provide a means to run poe without the debug socket. + +* The --enable-static-exec configure flag will only statically link libraries + if the static version of that library is present. If only the shared version + of a library exists (i.e., most system libraries on Solaris, AIX, and Mac, + for example, only have shared versions), the flag should still result in a + successful compilation, but note that the installed executables will not be + fully static. Thus, the only guarantee on these systems is that the + executable is statically linked with just the HDF5 library. + +* There is also a configure error on Altix machines that incorrectly reports + when a version of Szip without an encoder is being used. + +* On cobalt, an SGI Altix SMP ia64 system, Intel compiler version 10.1 (which + is the default on that system) does not work properly and results in + failures during make check (in a static build) and make installcheck (during + a shared build). This appears to be a compiler optimization problem. + Reducing optimization by setting CFLAGS to -O1 or below resolves the issue. + Alternatively, using a newer version of the compiler (11.0) also works as + intended. MAM - 2010/06/01 + +* h5diff will not report enum value differences when one or both of the values + is not a valid enumeration value. The source of this bug has been identified + and it will be fixed in 1.8.8. DER - 2011/04/27 %%%%1.8.6%%%% |
