c80d8cbe61 [svn-r24468] tfilters.h5 was created and checked in on 21 Feb 05, rev 10060, and never regenerated. The code for scaleoffset continued to change and the number of params for scaleoffset changed from 7 to 20 on the checkin of 23 Mar 05, rev 10384. 
The h5dump tests only looked at headers and never the data. Data reads would fail with invalid number of params (7 expected 20).
Regenerated file and replacement ddls updated.
New h5dump test will be added to read the data.

c24a7a7ba8 [svn-r20886] purpose: 
hdffv-7514 - GMQS: h5dump - improve effectiveness of testing scripts for handling expected output files

description:
    Removed top 3 lines from expected output file and update testing scripts 
    accordingly. These lines started to become maintainence headaches.
    First phase for h5dump test update. Next phase will be for h5ls.
    this is prerequisite for 'hdffv-7602 tools - upgrade tools' test scripts to share test files among tools, providing framework for test file re-usability.'

Tested:
    jam (linux32-LE), koala (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), cmake (jam)

bee6951ac6 [svn-r14906] Introduced a ratio formula compression ratio = uncompressed size / compressed size 
in the printing of the compression with 3 digits of precision per hdf-forum NASA developers suggestion

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
   }
}
}
