b2a2c17c44 [svn-r14895] RFC display compression ratio in h5dump
Here's the current behavior of h5dump regarding the printing of the dataset creation property list

For example

./h5dump -H -p -d filters

HDF5 "tfilters.h5" {
DATASET "deflate" {
   DATATYPE  H5T_STD_I32LE
   DATASPACE  SIMPLE { ( 20, 10 ) / ( 20, 10 ) }
   STORAGE_LAYOUT {
      CHUNKED ( 10, 5 )
      SIZE 385 
    }
   FILTERS {
      COMPRESSION DEFLATE { LEVEL 9 }
   }
   FILLVALUE {
      FILL_TIME H5D_FILL_TIME_IFSET
      VALUE  0
   }
   ALLOCATION_TIME {
      H5D_ALLOC_TIME_INCR
   }
}
}


The proposed behavior is to add this information after SIZE

SIZE 385 (51.9%COMPRESSION)

That percentage is obtained trough

Per = (b-a) / a

Where a = theoretical size obtained by multiplying datum size times number of elements
b =  size obtained with H5Dget_storage_size

The final print would look like

HDF5 "tfilters.h5" {
DATASET "deflate" {
   DATATYPE  H5T_STD_I32LE
   DATASPACE  SIMPLE { ( 20, 10 ) / ( 20, 10 ) }
   STORAGE_LAYOUT {
      CHUNKED ( 10, 5 )
      SIZE 385 (51.9%COMPRESSION)
    }
   FILTERS {
      COMPRESSION DEFLATE { LEVEL 9 }
   }
   FILLVALUE {
      FILL_TIME H5D_FILL_TIME_IFSET
      VALUE  0
   }
   ALLOCATION_TIME {
      H5D_ALLOC_TIME_INCR
   }
}
}

373d50bb3f [svn-r8826] Purpose:
h5dump new tests

Description:
added more tests for the escape/not escape feature for string data (with vlen, with
compound, with char data)

ba717ead8b [svn-r8749] Purpose:
dumper new features

Description:

1) added options for not printing : datasets, groups, datatypes, links
2) added a section for the user block
3) in the traversal routine, added the printing of an arrow for soft links and t
he word HARDLINK for hardlinks
   the print of the file contents is made during traversal , instead of at the e
   nd of it (this is helpful
       for very large files, where the wait time can be very long)
4) changed the description of the fill value properties
5) added a colon after the printing of the array indices

a5f1d15035 [svn-r8715] Purpose:
h5dump output change, new tests

Description:
the storage layout output format the storage layout output format  had some changes
same for the user defined filter
add an option (-y) for not printing the array indices (default is print indices )
the option for escaping non printable characters covers all characters (default is not escape)
(this might be not very portable, the test files are  tstring.ddl and tstringe.ddl )
add tests for the new options

78ca05e040 [svn-r8644] Purpose: h5dump new features
Description:

added the code for print strings with new line and display the path of references (new source files h5tools_ref.c and .h )
added a test suite in testh5dump.sh.in for
( note : to create testh5dump.sh , one must redo ./configure; this detects the availability of filters
and generates  testh5dump.sh accordingly)
1) storage layout
2) fill value
3) print reference with path
4) print strings with new lines
5) filters
