+
+Bug Fixes since HDF5-1.6.5 Release
+==================================
+
+    Library
+    -------
+        - Fixed several bugs with writing fill values for datasets that have
+            a variable-length datatype or component datatype.  QAK - 2007/06/19
+        - STDIO driver didn't support files bigger than 2GB because the OFFSET
+            parameter of fseek is of type LONG INT, not big enough for big 
+            files.  Use fseeko instead for big files if it's available on the 
+            system.  SLU - 2007/4/5
+        - 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.  PVN - 2007/2/19
+
+    Documentation 
+    ------------- 
+        - Corrected errors and extended the descriptions in Reference Manual 
+            entries for several functions.  
+
+    F90 API
+    -------
+        - None
+                                
+    C++ API
+    -------
+          - Changed
+                  StrType::StrType(const size_t& size);
+            to
+                  StrType::StrType(const int dummy, const size_t& size);
+            because the first one clashed with
+                  StrType::StrType(const hid_t existing_id); - BMR 2007/05/03
+          - Wrappers of H5Rcreate had incorrect prototypes.  Added these
+            overloaded functions:
+                  IdComponent::reference(void* ref, const char* name, DataSpace&
+                          dataspace, H5R_type_t ref_type = H5R_DATASET_REGION)
+                  IdComponent::void reference(void* ref, const char* name)
+                  IdComponent::reference(void* ref, const H5std_string& name)
+            and will remove these incorrect member functions:
+                  DataSet::Reference
+                  DataType::Reference
+                  Group::Reference
+                  H5File::Reference
+          - Added wrappers for H5Rdereference as constructors:
+                  DataSet(IdComponent& obj, void* ref);
+                  Group(IdComponent& obj, void* ref);
+                  DataType(IdComponent& obj, void* ref);

+Known Problems
+==============
+* 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
+  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.  JM - 2004/9/15

-            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

     F90 API
     -------
-        - None

     C++ API
     -------
-          - Changed
-                  StrType::StrType(const size_t& size);
-            to
-                  StrType::StrType(const int dummy, const size_t& size);
-            because the first one clashed with
-                  StrType::StrType(const hid_t existing_id); - BMR 2007/05/03
-          - Wrappers of H5Rcreate had incorrect prototypes.  Added these
-            overloaded functions:
-                  IdComponent::reference(void* ref, const char* name, DataSpace&
-                          dataspace, H5R_type_t ref_type = H5R_DATASET_REGION)
-                  IdComponent::void reference(void* ref, const char* name)
-                  IdComponent::reference(void* ref, const H5std_string& name)
-            and will remove these incorrect member functions:
-                  DataSet::Reference
-                  DataType::Reference
-                  Group::Reference
-                  H5File::Reference
-          - Added wrappers for H5Rdereference as constructors:
-                  DataSet(IdComponent& obj, void* ref);
-                  Group(IdComponent& obj, void* ref);
-                  DataType(IdComponent& obj, void* ref);
