The preprocessor #ifdefs around the DllMain + function allowed it to be compiled when the static library is built, + which is incorrect behavior that can cause linkage problems in + clients. + + The fix was to change the preprocessor #ifdefs to exclude compiling + DllMain() in static builds.

However, in the C wrapper the return + value of H5Literate is type herr_t, and this could cause + interoperability issues. + + The callback function should be declared INTEGER(C_INT) for + portability.

The minimum length of the buffers is now used in strncmp + to avoid overflow. + + (MSB - 2014/9/29, HDFFV-8670) + + - Behavior Change of H5LTdtype_to_text + + If a user buffer was passed in to H5LTdtype_to_text along with the + length, then the function would not truncate at the end of the + buffer, but would exceed the end of the user buffer. + + H5LTdtype_to_text was changed to truncate the string if the user + buffer is too small. + + (MSB - 2014/9/29, HDFFV-8855) + + Fortran High-level APIs: + ------ + - See entry for HDFFV-8912 above. + + Testing + ------- + - A subtest in parallel h5diff (ph5diff) testing was bypassed for the + local Linux 32 machine due to unknown issue in the previous version of + Mpich. The failure no long exists in the current Mpich. Therefore the + bypass is removed. (AKC - 2014/11/03 HDFFV-8954) + + - Fixed incorrect exit code values (was -1) in testframe which is commonly + used by several test programs. (AKC - 2014/07/22 HDFFV-8881) + + - Fixed Incorrect Exit Code Values in Testframe + The testframe which is commonly used by several test programs + had some incorrect exit code values.

Due to platform differences the return of + spurious data values has only been encountered on Windows 32-bit systems. + (Issue HDFFV-8247; JP - 2013/03/27) + +* The C++ and FORTRAN bindings are not currently working on FreeBSD with the + native release 8.2 compilers (4.2.1), but are working with gcc 4.6 from the + ports (and probably gcc releases after that). + (QAK - 2012/10/19) + +* The STDIO VFD does not work on some architectures, possibly due to 32/64 + bit or large file issues. The basic STDIO VFD test is known to fail on + 64-bit SunOS 5.10 on SPARC when built with -m64 and 32-bit OS X/Darwin + 10.7.0. The STDIO VFD test has been disabled while we investigate and + a fix should appear in a future release. + (DER - 2011/10/14 - HDFFV-8235) + +* h5diff can report inconsistent results when comparing datasets of enum type + that contain invalid values. This is due to how enum types are handled in + the library and will be addressed in a future release. + (DER - 2011/10/14 - HDFFV-7527) + +* The links test can fail under the stdio VFD due to some issues with external + links. This will be investigated and fixed in a future release. + (DER - 2011/10/14 - HDFFV-7768) + +* After the shared library 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) + +* 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) + +* 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/ + (NAF - 2011/01/19) + +* 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 - 2010/02/02) + +* 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. + (MAM - 2009/11/04) + +* 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) + +* 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 - 2005/06/30) + + %%%%1.8.13%%%% |
