h5diff issues "unable to read attribute" error message when comparing two files
Description:
h5diff did not handle attributes of variable length strings correctly. It created the wrong memory type if one but not both compared attributes are of the variable strings type. It ended in H5Aread() failure.
Solution:
We decided to treat the case when one type is variable length string and the other is not as incomparable. That bypassed the above error. We still need to figure out the proper way, if possible, to compare variable string with non-variable string types.
Tested: h5committested plus tested in Swallow (OS X 10.8).
h5diff segfaults with user's files
Solution:
Added a variable to indicate if real data are in the buffer and will call H5Dvlen_reclaim()
only when real data are in the buffer.
Tested: with the user provided data files and no more segmentaion fault.
Also h5committ tested.
HDFFV-7643 - h5diff - incorrect exit-code returns for extra attribute exist
Description:
h5diff: Fixed to return correct exit code 1 when detect unique
attribute. Prior to this fix, h5diff returned exit code 0 indicating
two files are identical.
Tested:

HDFFV-8145 h5diff slowness with version >= 1.8.7
Description:
Improved speed when comparing HDF5 files with lots of attributes. Much slower performance was identified with release version from 1.8.7 to 1.8.10 compared to 1.8.6.
Tested:

Address HDFFV-7942 - h5diff: incorrect result for comparing attribute data with different type size in same class
Description:
When comparing attribute data values with same type class but different size, the result was incorrect. It was due to the size difference and got truncated.
Fixed to match up the smaller type size to big type size like what dataset does.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows (32-LE cmake), cmake (jam)
HDFFV-7770 - h5diff segmentation fault on JPSS files
Description:

HDFFV-7693 - h5diff produces different behavior between versions: 1.8.3 and 1.8.6
Description:
There were two issues on this.
One was not displaying all the comparable objects if non-comparable
object/attribute exist and compared before comparables ones. This issue
occurred after 1.8.4 release. This is the issue from user.
The other issue was not displaying all the comparable attributes,
if non-comparable object/attribute exist and compared ahead. This issue
were exist even before 1.8.4 release. So it's possible some attribute
comparison may have not displayed correctly in the past, if non-comparable
data were exist in common object.
Fixed h5diff to display all the comparable object and attribute regardless
of non-comparables.
Tested:
jam (linux32-LE), koala (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Cmake (jam, Windows)
Fixed CHICAGO: Bug 2121 - h5diff - incorrect and lack of output for the
different set of attributes (different number and names)
Description:
Previously h5diff compared attributes correctly only when two objects have
the same number of attributes and attribute names are identical.
This fix covers all other cases.
Also didn't display useful information about attribute difference.
This fixes both issues.
Tested:
jam (linux32-LE), amani (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE)
Improve the previous fix for Bug 2216 - GMQS: h5diff - memory leak when
compares vlen string in dataset or attributes
Description:
Related to the previous checkin r20270 and r20266.
Improve h5tools_detect_vlen() code for better performance. H5Tdetect_class
already recusive on given type so don't need to be part of recusive call
again. Also improve error handlings in h5tools_detect_vlen and
h5tools_detect_vlen_str functions.
Also updated h5ls and h5dump code accordingly.

Description:
Improve the fix along with the previous checkin r20266.
Add a new function to tool lib, h5tools_detect_vlen_data() which return
TRUE if include any kind of vlen data all at once, either VLEN-data or
VLEN-string and so on.
Also updated h5ls and h5dump code accordingly.
Tested:

Bring changes from Coverity branch to trunk:
r19975:
Fixed potential mem leak at H5O_attr_open_by_name
r19980:
Fix coverity issue 792.
Free tmp_env_prefix in H5Lexternal.c line 365 if it is not NULL but its contents are 0 when it goes out of scope.
r20039:
Eliminate warnings about nested extern and implicit declarations of parallel_print and address Coverity defects 712-781 by #including h5tools_utils.h in h5diff_array.c, h5diff_attr.c, h5diff_dset.c and h5diff_util.c.
r20046:
Purpose: Address TOCTOU warnings in h5jam and h5unjam
Description: Coverity is afraid that the state of the input file could change
between the call to stat() and the call to open(). This is called a time-of-
check time-of-use (TOCTOU) vulnerability. Modified stat calls to fstat which
uses an open file pointer so it (hopefully) won't complain any more.
r20047:
Addressed coverity issues 135-137, 462-464. Local pointers that needed to be freed in case of error were moved out of a switch statement in src/H5Tnative.c, set to NULL, and checked before freeing.
Tested on:
Mac OS X/32 10.6.6 (amazon) w/debug & production
(h5committested on Coverity branch)
Bring changes from Coverity branch to trunk:
r19930:
Fix memory leaks involving VL attributes in h5repack and h5diff. The buffers in
copy_attr and diff_attr were not checked for the presence of a vlen before being
freed, and vlen storage was never reclaimed. Added checks and calls to
H5D_vlen_reclaim().
r19933:
Purpose: Fix memory leak in H5L_move_cb()
Description: H5L_move_cb copied the source link using H5O_msg_copy() but freed
it manually using H5MM_xfree(). Since H5O_link_copy allocates the link using
H5FL_MALLOC, this causes the link to be allocated from the free list but is
never put back on the free list when it is freed. This prevents the link free
list from shutting down properly. Modified H5L_move_cb() and H5L_move_dest_cb()
to free the link properly using H5O_msg_free().
r19973:
Fix resource leaks by freeing string created by HD5f2string
r19974:
Issue #345: Inialize buf variable to null
Tested on:

Additional fix relted to the fix of bug1672.
Description:
The fix of bug1672 caused some changes of output which required modifying
some test cases. After some discussion, restoring the changes of the test
cases was decided. After many experiments for the solution, this fix was
made so the code which improved performance can stay.
Tested on Jam.
Fix potential problem similar to Bug1672 (getting garbage values)
Description:
This will resolve the potential problem like Bug1672 when comparing
attributes. It improves the performance by not calling diff_array
twice. (diffing time in half). Little clean up on comment lines.
Refer to the Bug fix 1672. (also svn revision 17905 on trunk)
Tested on:
linux32 (jam) , linux64 (almani), solaris (linew)
Solution: for compound types, recursively apply that check
Two new cases are added
1) the compound type has a different number of members. Message printed is
<obj1> has X members <obj2> has Y members
Where X and Y are the number of members of each compound type being compared
2) the compound type has not comparable types (for example a double and an int at the same index)
In this case the message
Comparison not possible: object1 is of class1 and object2 is of class2
Is replaced with
Comparison not possible: object1 has a class1 and object2 has a class2
Modified the test generator program to have these 2 cases
Added a shell run for these 2 cases
Tested: windows, h5committest

Tested platform:
Kagiso only since it is only a comment block change. If it works in one
machine, it should work in all, I hope. Still need to check the parallel
build on copper.
1) added a new parameter to the h5diff function diff_array that contains
the beginning position of the hyperslab, so that the total position in
the array is printed correctly when reading by hyperslabs.
2) added a new test to h5diff that reads and diffs by hyperslabs. The
test reads a 1GB dataset, from which a 1KB hyperslab was written with
differences .
3) added the generation of 2 files to the generator program to test the
h5diff hyperslab read.
4) changed the h5diff binary pre-generated file names to be more
descriptive (e.g, instead of file1.h5, made it h5diff_basic1.h5)
5) changed the name of the h5repack options text file to info.h5repack
Code cleanup

Misc. update:
bug fix
a call to sprintf was giving incorrect output in the system Fedora Core 4 with gcc 4.0

Too minor to require h5committest
bug fix
Description:
when 2 objects were not comparable, the final print information for the non verbose mode printed "0 differences found"
Solution:
replaced instead with a Summary message that says
"Some objects were not comparable"
Platforms tested:
linux
solaris
Misc. update:
Fixed numerous ph5diff bugs.
Description:
Fixed manager output printing
Fixed out of order output printing
Fixed test script execution problem
Temporary fix for large amounts of output overflowing buffer.
Solution:
The manager task buffers its output. However, since the manager task
never gets a print token, this output was lost. Solution: new function called
print_manager_output that prints buffered output is called in places where the
manager buffers its output.
printf was apparently buffering output. This means that a task would sometimes
print even after it had given up its print token. Added fflush() call after
printf() calls, which seems to have fixed the problem.
calling rsh multiple times in succession seems to overwhelm something in Linux,
as it begins to refuse new connections until the old ones reset. Since each
call to mpirun in the test script starts up 4 rsh sessions, the test script
eventually is unable to run any further tests. Solution: Added a short delay in the
testscript between successive calls to mpirun to allow old connections to reset.
The 10k output buffer was of insufficient size to hold the large amounts of
output generated by some of the tests. Since code to buffer to a file has not
been implemented yet, a temporary fix was to increase the size of the output
buffer to 50k.
Platforms tested:
