Initial work has targeted Windows, but other platforms + can be used. See the CMake.TXT file for more information. Version + 2.8.1 of CMake is required. + - Configure now adds appropriate defines for supporting large (64-bit) + files on all systems, where supported, by default, instead of only Linux. + This large file support is controllable with the --enable-largefile + configure option. The Linux-specific --enable-linux-lfs option has been + deprecated in favor of this new option. Please note that specifying + --disable-large does NOT attempt to "turn off" largefile support if it + is natively supported by the compiler, but rather just disables + configure from actively trying to add any additional compiler flags. + (MAM - 2010/05/05 - Bug # 1772/1434) + - Fixed an signal handling mask error in H5detect that might result in + SIGBUS or SIGSEGV failures in some platforms such as Linux on Sparc. + (AKC - 2010/4/28 - Bug # 1764) + - Fixed various "strict aliasing" problems, allowing higher levels + of compiler optimization (in particular, allowing '-O3' to work + with recent versions of GCC). (QAK - 2010/04/26) + - Upgraded versions of autotools used to generate configuration suite. + We now use Automake 1.11.1, Autoconf 2.65, and Libtool 2.2.6b. + (MAM - 2010/04/15) + - Added the xlc-* and mpcc_r-* BASENAME patterns to be recognized as IBM + compilers so that the IBM compiler options can be added properly. This + allows non-system-default compiler command names (e.g. xlc-m.n.k.l) be + recognized. (AKC - 2009/11/26) + + Library + ------- + - Performance is substantially improved when extending a dataset with early + allocation. (NAF - 2010/03/24 - Bug # 1637) + - Added support for filtering densely stored groups. Many of the API + functions related to filters have been extended to support dense groups + as well as datasets. Pipeline messages can now be stored in a group's + object header. (NAF/QAK - 2009/11/3) + + Parallel Library + ---------------- + - None + + Tools + ----- + - h5dump: Added the new packed bits feature which prints packed bits stored + in an integer dataset. (AKC/ADB - 2010/5/7) + - h5diff: Fixed incorrect behavior (hang) in parallel mode when specifying + invalid options (ex: -v and -q). (JKM - 2010/02/17) + - h5diff: Added new flag --no-dangling-links (see --help for details). + (JKM - 2010/02/10) + - h5diff: Added new flag --follow-symlinks (see --help for details). + (JKM - 2010/01/25) + - h5diff: Added a fix to correct the display of garbage values when + displaying big-endian data on a little-endian machine.

(BMR - 2009/07/26) + + +Support for New Platforms, Languages, and Compilers +=================================================== + - AIX 6.1 has been added. (AKC - 2010/1/4) + + +Bug Fixes since HDF5-1.8.4 +========================== + + Configuration + ------------- + - Fixed various "strict aliasing" problems, allowing higher levels + of compiler optimization (in particular, allowing '-O3' to work + with recent versions of GCC). (QAK - 2010/04/26) + + Library + ------- + - Fixed a file corruption bug that could happen when shrinking a compressed + dataset. (NAF - 2010/05/20) + - Fixed some memory leaks in VL datatype conversion when strings are + used as fill values. (MAM - 2010/05/12 - Bug # 1826) + - Fixed an H5Rcreate failure when passing in a -1 for the dataspace + identifier. (ADB - 2010/4/28) + - Fixed a bug when copying objects with NULL references with the + H5O_COPY_EXPAND_REFERENCE_FLAG flag set. (NAF - 2010/04/08 - Bug # 1815) + - Added a mechanism to the H5I interface to save returned object identifier + structures for immediate re-use if needed. This addresses a potential + performance issue by delaying the case when the next identifier to be + registered has grown so large that it wraps around and needs to be + checked to see whether it is available for distribution. + (MAM - 2010/03/15 - Bug # 1730) + - Files can now be concurrently opened more than once using the core file + driver, as long as the backing store is used. (NAF - 2010/03/09) + - Added support for H5O_COPY_EXPAND_EXT_LINK_FLAG to H5Ocopy. External + links will now be expanded if this flag is set. + (NAF - 2010/03/05 - Bug # 1733) + - Fixed a bug where the library, when traversing an external link, would + reopen the source file if nothing else worked. (NAF - 2010/03/05) + - Fixed a bug where fractal heap identifiers for attributes and shared + object header messages could be incorrectly encoded in the file for + files created on big-endian platforms. + Please see http://www.hdfgroup.org/HDF5/release/known_problems if you + suspect you have a file with this problem. + (QAK - 2010/02/23 - Bug # 1755) + - Fixed an intermittent bug in the b-tree code which could be triggered + by expanding and shrinking chunked datasets in certain ways. + (NAF - 2010/02/16) + - H5Tdetect_class said a VL string is a string type. But when it's in + a compound type, it said it's a VL type. THis has been fixed to be + consistent; it now always returns a string type. + (SLU - 2009/12/10 - Bug # 1584) + - Allow "child" files from external links to be correctly located when + relative to a "parent" file that is opened through a symbolic link. + (QAK - 2009/12/01) + + Parallel Library + ---------------- + - Parallel mode in AIX will fail some of the testcheck_version.sh tests + where it treats "exit(134) the same as if process 0 had received an abort + signal. Fixed. (AKC - 2009/11/3) + + Tools + ----- + - Fixed h5ls to return exit code 1 (error) when a non-existent file is + specified. (JKM - 2010/04/27 - Bug # 1793) + - Fixed h5copy failure when copying a dangling link that is specified + directly. (JKM - 2010/04/22 - Bug # 1817) + - Fixed an h5repack failure that lost attributes from a dataset of + reference type. (JKM - 2010/3/25 - Bug # 1726) + - Fixed h5repack error that set NULL for object reference values for + datasets, groups, or named datatypes. (JKM - 2010/03/19 - Bug # 1814) + + F90 API + ------ + - None + + C++ API + ------ + - The constructor PropList::PropList(id) was fixed to act properly + according to the nature of 'id'. When 'id' is a property class + identifier, a new property list will be created. When 'id' is a + property list identifier, a copy of the property list will be made. + (BMR - 2010/5/9) + - The parameters 'size' and 'bufsize' in CommonFG::getLinkval and + CommonFG::getComment, respectively, now have default values for the + user's convenience. (BMR - 2009/10/23) + - NULL pointer accessing was fixed. (BMR - 2009/10/05 - Bug # 1061) + - Read/write methods of DataSet and Attribute classes were fixed + to handle string correctly. (BMR - 2009/07/26) + + High-Level APIs: + ------ + - Fixed a bug in H5DSattach_scale, H5DSis_attached, and H5DSdetach_scale + caused by using the H5Tget_native_type function to determine the native + type for reading the REFERENCE_LIST attribute. This bug was exposed + on Mac PPC. (EIP - 2010/05/22 - Bug # 1851) + - Fixed a bug in the H5DSdetach_scale function when 0 bytes were + allocated after the last reference to a dimension scale was removed + from the list of references in a VL element of the DIMENSION_LIST + attribute. Modified the function to comply with the specification: + the DIMENSION_LIST attribute is now deleted when no dimension scales + are left attached.

The + library's own conversion works correctly. A macro is defined 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 a new parameter added to + get_eoa and set_eoa callback functions. A new callback function + get_type_map was added. 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 it into a 1.8 library. This affects a very small + number of users. (See bug report #1279.) 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 + +* Some tests in tools/h5repack may fail in AIX systems when -q32 mode is used. + The error is due to insufficient memory requested. Request a large amount + of runtime memory by setting the following environment variable for more + memory. + LDR_CNTRL=MAXDATA=0x20000000@DSA + AKC - 2009/10/31 + +* The PathScale MPI implementation, accessing a Panasas file system, would + cause H5Fcreate() with H5F_ACC_EXCL to fail even when the file is not + existing. This is due to the MPI_File_open() call failing if the amode 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 gcc v4.3 and v4.4, with production mode, if -O3 is used, H5Tinit.c + would fail to compile. Actually bad H5Tinit.c is produced. If -O (same + as -O1) is used, H5Tinit.c compiled okay but test/dt_arith would fail. + When -O0 (no optimizatio) is used, H5Tinit.c compilete okay and all + tests passed. Therefore, -O0 is imposed for v4.3 and v4.4 of gcc. + AKC - 2009/04/20 + +* 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.

This interferes with + test suites that do not expect seeing 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 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 FREE-BSD systems when shared libraries are disabled, make install fails + in install-examples with the error '"Makefile", line 635: Need an operator'. + When this error occurs removing or commenting out the line "export + LD_LIBRARY_PATH=$(LL_PATH)" (line 635 in examples/Makefile) will allow make + install to finish installing examples. The problem will be fixed in the + next release. LRK - 2010/05/26 + +* 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.
