HDFFV-5919 - GMQS: h5diff - The number of object difference is not consistent between dataset and group/type when attribute(s) have differences
Description:
Object differences are not consistent between dataset and group/datatype when their attribute(s) have differences. This is because attribute(s) differences is not accumulated to group or datatype object’s difference, but accumulated to dataset difference.
To fix, do not accumulate attribute difference to dataset difference. This is referred to h5diff’s default behavior and also past report from users that users were confused by the accumulated behavior. (also can’t figure out only for dataset difference , also hard to spot dataset difference when it has lots of attributes or differences)
This also lead to fix inconsistent format indicating difference between dataset and group/datatype object.

Purpose:
HDFFV-8003 - ph5diff (parallel h5diff): daily test failure on ember intermittently during non comparable test file comparison
HDFFV-7755 - parallel h5diff : hanging on koala intermittently during non comparable test file comparison
Description:
non-comparable test intermittently hung on koala and ember, but not on jam. it didn't occur until -np reaches 4 or bigger. it occurred once out of many repeated attempts of the same test.
There was a incorrectly (mistakenly?) duplicated code in MPI section which caused such hang in a certain condition. The test used more processes than other tests, which increased chance to trigger more undone processes, and such process could enter the incorrect code section and wait for wrong pair of send. it explains why it occurred intermittently according to machine condition and using a certain feature.
Removed incorrect code which blocked correct code.
Tested: some manually repeated test performed

Fix for HDFFV-7998-h5diff: incorrect behavior and output for comparing symbolic dangling links without following-symlinks option
Description:
Fix not to check and display dangling link status without --follow-symlinks option.
Berfor the fix, when comparing symbolic link to symbolic link without follow-symlinks option, h5diff followed to check if those links are dangling or not. It caused to display output incorrectly (dangling link instead of symbolic link).
The fix also improved performance when comparing lots of symbolic links without the --follow-symlinks option.
Test cases were added and tagged with jira#.

Fix for HDFFV-7644 GMQS: h5diff - incorrect behaviors when comparing HDF5 files with different type of objects (dataset, group, type) as common objects
Description:
Fixed failure for comparing same named object with different object types in comparing groups. (common object comparison)
Prior to the fix, h5diff resulted in error. After the fix, h5diff detects such case as non-comparable and display messages accordingly.
Test cases were added and tagged with jira#.

Fix for HDFFV-7837 - h5diff: incorrect behavior with exclude-path option when unique object exist only in one file
Description:
If unique objects exists only in one file and try to exclude
the unique objects with --exclude-path option, h5diff missed
excluding some objects.
Fixed to exclude objects correctly in such case.

Fix for HDFFV-7835 h5diff: incorrect result for comparing the two same type symlinks as dangling links.
Description:
When two symbolic dangling links are compared with --follow-symlinks option,
the result should be same. It works for comparing two files, but didn't work
for comparing two objects.

Fix for HDFFV-7836 h5diff: displays error stack message for comparing the two dangling symlink with follow-symlinks option
Description:
While ago, to improve performance, skipping same object checking
(h5tools_is_obj_same()) was added.
However the checking function doesn't understand about the dangling link and
caused the issue.
Since handling dangling link code section already implemented, move the
checking function after handling dangling-links to address the problem.
Test was added and tagged with jira#.

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.

- HDFFV-5928 - GMQS: h5diff problem and improvement on comparsing the same objects
Description:
Fixed:
1) adding h5tools_is_obj_same() function to check if two given IDs or paths point to the same object. This function can be very useful for other tools and applications.
2) using h5tools_is_obj_same() at h5diff() and diff() in h5diff.c. If two paths point to the same object, there is no need to check the details of the object since we know there is no difference. The fix will increase the performance by skipping the content comparison. It also fixed the problem of reporting difference for some cases of comparing the same file, e.g. empty files or files with incomparable objects the same file.
Test update:
Updat prvious test cases (171, 172, 530) affected by this fix, so they
still perfrom originally intended testing without bypassing.
Tested:

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.

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.

(Need to discuss related feature)
Tested on Jam
Add a feature to compare through links. Relate to bugzilla report 1754.
Description:
Currently, h5diff command only compares the name(path) of target object
not the actual data. With this feature, h5diff will go through the link(s)
and figure out the actual object at the end of the link and compare data
if exist. Internally we have hard-link, soft-link, external-link (as part
of user_defined-link). This feature will provide a user transparent
experience when comparing link objects as the user can specify any of
those 3 type of links to be compared in any combination.
Tested on Jam.
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 Bug1672 - Display garbage value on LE machine for BE data.
Description:
Casuing by calling diff_dataset twice when -r or no option was given.
Change to call it once which fix the problem.
It also improves the performance. (diffing time in half)
According further test, it also occurred on BE machine as well and it
seems occruing only with the BE data attached to Bugzilla.
Don't know how the file was created. Anyway this fix will prevent
from diffing with garbage values in similiar potential case.
Tested on:
linux32 (jam) , linux64 (almani), solaris (linew)
The file used for input is located in the common source tools for testfiles, in tools/testfiles
Modified the h5repack shell script to read files from this location (h5repack reads its input files from a dedicated testfiles location in h5repack/testfiles)
Changed the h5diff open file call to use h5tools_fopen, so that it can open all file drivers
Tested: windows, linux, solaris
* Pedro Vicente, pvn@hdfgroup.org, Nov 4, 2008
* Compare the graph and make h5diff return 1 for difference if
* 1) the number of objects in file1 is not the same as in file2
* 2) the graph does not match, i.e same names (absolute path)
* 3) objects with the same name are not of the same type
Remove trailing whitespace from C/C++ source files, with the following

Mac OS X/32 10.5.5 (amazon)
No need for h5committest, just whitespace changes...
Summary: when using h5diff to compare the results of h5repack (or other tools that copy one HDF5 file to another), a new option is needed to allow h5diff to make an "absolute" comparison of the 2 files. This is the "contents" mode explained in the usage below.
If this mode is present, objects in both files must match (must be exactly the same). If this does not happen, the tool returns an error code of 1 (instead of the success code of 0)
Changes to the h5repack test script: the call to h5diff was changed to include -c (maintaining the previous -q).
tested: windows, linux, solaris
