[svn-r21072] Purpose:
Work for HDFFV-7600 - GMQS: h5diff - argument options -d, -p and --use-system-epsilon should be mutually exclusive.
Description:
Fixed h5diff to display instructive error message and exit with 1
when mutually exclusive options (-d, -p and --use-system-epsilon)
are used together.
Tested:
jam (linux32-LE), koala (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Cmake (jam)

OPTIONS
|
||||
-h, --help Print a usage message and exit.
|
||||
-V, --version Print version number and exit.
|
||||
-r, --report Report mode. Print differences.
|
||||
-v --verbose Verbose mode. Print differences information and list
|
||||
of objects.
|
||||
-vN --verbose=N Verbose mode with level. Print differences and list
|
||||
of objects.
|
||||
Level of detail depends on value of N:
|
||||
0 : Identical to '-v' or '--verbose'.
|
||||
1 : All level 0 information plus one-line attribute
|
||||
status summary.
|
||||
2 : All level 1 information plus extended attribute
|
||||
status report.
|
||||
-q, --quiet Quiet mode. Do not produce output.
|
||||
--follow-symlinks Follow symbolic links (soft links and external links)
|
||||
and compare the links' target objects.
|
||||
If symbolic link(s) with the same name exist in the
|
||||
files being compared, then determine whether the
|
||||
target of each link is an existing object (dataset,
|
||||
group, or named datatype) or the link is a dangling
|
||||
link (a soft or external link pointing to a target
|
||||
object that does not yet exist).
|
||||
- If both symbolic links are dangling links, they
|
||||
are treated as being the same; by default, h5diff
|
||||
returns an exit code of 0. If, however,
|
||||
--no-dangling-links is used with --follow-symlinks,
|
||||
this situation is treated as an error and h5diff
|
||||
returns an exit code of 2.
|
||||
- If only one of the two links is a dangling link,
|
||||
they are treated as being different and h5diff
|
||||
returns an exit code of 1. If, however,
|
||||
--no-dangling-links is used with --follow-symlinks,
|
||||
this situation is treated as an error and h5diff
|
||||
returns an exit code of 2.
|
||||
- If both symbolic links point to existing objects,
|
||||
h5diff compares the two objects.
|
||||
If any symbolic link specified in the call to h5diff
|
||||
does not exist, h5diff treats it as an error and
|
||||
returns an exit code of 2.
|
||||
--no-dangling-links Must be used with --follow-symlinks option;
|
||||
otherwise, h5diff shows error message and returns
|
||||
an exit code of 2.
|
||||
Check for any symbolic links (soft links or external
|
||||
links) that do not resolve to an existing object
|
||||
(dataset, group, or named datatype). If any
|
||||
dangling link is found, this situation is treated as
|
||||
an error and h5diff returns an exit code of 2.
|
||||
-c, --compare List objects that are not comparable
|
||||
-N, --nan Avoid NaNs detection
|
||||
-n C, --count=C Print differences up to C number, C is a positive
|
||||
integer.
|
||||
-d D, --delta=D Print difference if (|a-b| > D), D is a positive
|
||||
number.
|
||||
-p R, --relative=R Print difference if (|(a-b)/b| > R), R is a positive
|
||||
number.
|
||||
--use-system-epsilon Print difference if (|a-b| > EPSILON), EPSILON is
|
||||
a system epsilon value.
|
||||
If the system epsilon is not defined, the below
|
||||
one of the following predefined values will be used:
|
||||
FLT_EPSILON = 1.19209E-07 for floating-point type
|
||||
DBL_EPSILON = 2.22045E-16 for double percision type
|
||||
--exclude-path "path" Exclude the specified path to an object when
|
||||
comparing files or groups. If a group is excluded,
|
||||
all member objects will also be excluded.
|
||||
The specified path is excluded wherever it occurs.
|
||||
This flexibility enables the same option to exclude
|
||||
either objects that exist only in one file or
|
||||
common objects that are known to differ.
|
||||
-h, --help
|
||||
Print a usage message and exit.
|

-V, --version
|
||||
Print version number and exit.
|
||||
-r, --report
|
||||
Report mode. Print differences.
|
||||
-v --verbose
|
||||
Verbose mode. Print differences information and list of objects.
|
||||
-vN --verbose=N
|
||||
Verbose mode with level. Print differences and list of objects.
|

0 : Identical to '-v' or '--verbose'.

-q, --quiet
|
||||
Quiet mode. Do not produce output.
|
||||
--follow-symlinks
|
||||
Follow symbolic links (soft links and external links and compare the)
|
||||
links' target objects.
|
||||
If symbolic link(s) with the same name exist in the files being
|
||||
compared, then determine whether the target of each link is an existing
|
||||
object (dataset, group, or named datatype) or the link is a dangling
|
||||
link (a soft or external link pointing to a target object that does
|
||||
not yet exist).
|
||||
- If both symbolic links are dangling links, they are treated as being
|
||||
the same; by default, h5diff returns an exit code of 0.

this situation is treated as an error and h5diff returns an
|
||||
exit code of 2.
|
||||
- If only one of the two links is a dangling link,they are treated as
|
||||

this situation is treated as an error and h5diff returns an
|
||||
exit code of 2.

- If both symbolic links point to existing objects, h5diff compares the
|
||||
two objects.

If any symbolic link specified in the call to h5diff does not exist,
|

h5diff treats it as an error and returns an exit code of 2.
|

--no-dangling-links
|
||||
Must be used with --follow-symlinks option; otherwise, h5diff shows
|
||||
error message and returns an exit code of 2.
|
||||
Check for any symbolic links (soft links or external links) that do not
|
||||
resolve to an existing object (dataset, group, or named datatype).
|
||||
If any dangling link is found, this situation is treated as an error
|
||||
and h5diff returns an exit code of 2.
|
||||
-c, --compare
|
||||
List objects that are not comparable
|
||||
-N, --nan
|
||||
Avoid NaNs detection
|
||||
-n C, --count=C
|
||||
Print differences up to C. C must be a positive integer.
|
||||
-d D, --delta=D
|
||||
Print difference if (|a-b| > D). D must be a positive number.
|
||||
Can not use with '-p' or '--use-system-epsilon'.
|
||||
-p R, --relative=R
|
||||
Print difference if (|(a-b)/b| > R). R must be a positive number.
|
||||
Can not use with '-d' or '--use-system-epsilon'.
|
||||
--use-system-epsilon
|
||||
Print difference if (|a-b| > EPSILON), EPSILON is system defined value.
|
||||
If the system epsilon is not defined,one of the following predefined
|
||||
values will be used:
|
||||
FLT_EPSILON = 1.19209E-07 for floating-point type
|
||||
DBL_EPSILON = 2.22045E-16 for double precision type
|
||||
Can not use with '-p' or '-d'.
|
||||
--exclude-path "path"
|
||||
Exclude the specified path to an object when comparing files or groups.
|
||||
If a group is excluded, all member objects will also be excluded.
|
||||
The specified path is excluded wherever it occurs.
|
||||
This flexibility enables the same option to exclude either objects that
|
||||
exist only in one file or common objects that are known to differ.
|
||||
|
||||
When comparing files, "path" is the absolute path to
|
||||
the excluded object; when comparing groups, "path" is
|
||||
similar to the relative path from the group to the
|
||||
excluded object. This "path" can be taken from the
|
||||
first section of the output of the --verbose option.
|
||||
For example, if you are comparing the group /groupA
|
||||
in two files and you want to exclude
|
||||
/groupA/groupB/groupC in both files, the exclude
|
||||
option would read as follows:
|
||||
--exclude-path "/groupB/groupC"
|
||||
When comparing files, "path" is the absolute path to the excluded;
|
||||
object; when comparing groups, "path" is similar to the relative
|
||||
path from the group to the excluded object. This "path" can be
|
||||
taken from the first section of the output of the --verbose option.
|
||||
For example, if you are comparing the group /groupA in two files and
|
||||
you want to exclude /groupA/groupB/groupC in both files, the exclude
|
||||
option would read as follows:
|
||||
--exclude-path "/groupB/groupC"
|
||||
|
||||
If there are multiple paths to an object, only the
|
||||
specified path(s) will be excluded; the comparison
|
||||
will include any path not explicitly excluded.
|
||||
This option can be used repeatedly to exclude
|
||||
multiple paths.
|
||||
If there are multiple paths to an object, only the specified path(s)
|
||||
will be excluded; the comparison will include any path not explicitly
|
||||
excluded.
|
||||
This option can be used repeatedly to exclude multiple paths.
|
||||
|
||||
Modes of output:
|
||||
Default mode: print the number of differences found and where they occured
