Release of HDF5-1.8.12

The HDF5-1.8.12 release is now available, and can be downloaded from the
HDF Group Downloads page:

     http://www.hdfgroup.org/downloads/

It can also be obtained directly from:

     http://www.hdfgroup.org/HDF5/release/obtain5.html

HDF5-1.8.12 is a minor release, with a few new features and changes,
including:

   o An option was added to specify the location of a default plugin
     (dynamically loaded filter) when building HDF5.

     The configure option is: --with-default-plugindir=location
     The CMake option is: -DH5_DEFAULT_PLUGINDIR:PATH=location

   o The h5repack utility was updated to use plugin filters (dynamically
     loaded filters) to read and write files.

   o The following options were added to h5dump:

     - The "-N" or "--any_path" option searches the file for paths that
       match the search path.

     - The "-A 0" option excludes the display of attributes.

   o Several changes were made to the C++ APIs. Some wrappers and
     overloaded convenience functions were added, as well as a new
     class, H5::H5Location.

This release contains many other changes that are not listed here.
Please be sure to read the Release Notes for a comprehensive list of
new features and changes:

     http://www.hdfgroup.org/ftp/HDF5/current/src/hdf5-1.8.12-RELEASE.txt

Changes that affect maintainers of HDF5-dependent applications are
listed in "HDF5 Software Changes from Release to Release":

     http://www.hdfgroup.org/HDF5/doc/ADGuide/Changes.html

Future Changes to Supported Platforms
-------------------------------------

Please be aware that after this release we will be moving our current
standard for Windows from Windows 7 VS 2010 Intel Fortran 12 to
Windows 7 VS 2012 Intel Fortran 13. All versions will continue to be
tested but only pre-built binaries for VS 2012 Intel Fortran 13 will
be provided on the web site.

In addition, we plan to drop support for Mac OS X 10.6, move to
CMake 2.8.14, and upgrade the GNU Autotools to the latest version.

Let us know if you have any concerns about these upcoming changes.

Release of h4mapwriter version 1.0.6

Version 1.0.6 of the h4mapwriter utility is now available and can be
downloaded from the h4mapwriter project page:

     http://www.hdfgroup.org/projects/h4map/h4map_writer.html

The 1.0.6 release improves error handling of unmappable objects.

The h4mapwriter is a utility that creates an HDF4 file content map in
XML for a given HDF4 file. It enables the data to be retrieved from
an HDF4 file without relying on the HDF4 library.

Release of h5edit 1.2.0

Version 1.2.0 of h5edit is available from the JPSS project Downloads
page:

     http://www.hdfgroup.org/projects/jpss/jpss_downloads.html

New features in this release include:

   o Added support for the MODIFY command.
   o Added support for Mac OS X Mountain Lion 10.8.4.

The h5edit tool is a general command line tool to edit HDF5 files.
The current version is limited to operations on attributes only. For
more information see:

     http://www.hdfgroup.org/projects/jpss/h5edit_index.html

Book Release of "Python and HDF5"

We are pleased to announce the release this month of a new O'Reilly
book by Andrew Collette entitled "Python and HDF5". For more
information see:

     http://shop.oreilly.com/product/0636920030249.do

-------------------------------------------------------------
For questions regarding these or other HDF issues, contact:

     help@hdfgroup.org

I understand that you have now added a plugin mechanism, but I can't
find documentation for it. Is there already documentation on that
feature (detailing what to do to write a plugin, for instance), and
where can I find it?

Cheers,
Nathanael

I have the same question, a little bit more specific: how can I create a plugin for the LZF commpression and install it such that h5ls and h5dump can use it?

Greetings, Richard

Hi Richard and Nathanael,

Please check this document http://www.hdfgroup.org/HDF5/doc/Advanced/DynamicallyLoadedFilters/HDF5DynamicallyLoadedFilters.pdf

It points to the bzip2 example that you could follow. Let help@hdfgroup.org know if you have any questions after reading the document.

Richard,

You should use the filter number for LZF that is registered with The HDF Group http://www.hdfgroup.org/services/contributions.html#filters

Good luck :slight_smile:

Hello Elena,
yes, that article answered all of my questions, thanks.

I think, people reading about the filter and compression interface
should be made aware of this document, so I would suggest that it is
linked to the documentation page about the filter and compression
interface (http://www.hdfgroup.org/HDF5/doc/RM/RM_H5Z.html).

Hello Elena,
I have just finished adapting our MAFISC plugin to the new plugin scheme
(it's available at the old site:
http://wr.informatik.uni-hamburg.de/research/projects/icomex/mafisc),
however, during my testing, I came across this little problem:

I can compress a file with
  h5repack --filter=UD=32002,1,0 source.h5 dest.h5

I can also read it with
  h5dump dest.h5 | less

I can copy is with
  h5repack dest.h5 dest2.h5

But I cannot uncompress it with
  h5repack --filter=NONE dest.h5 unpacked.h5

because --filter=NONE _deactivates_ dynamically loaded filters while
reading the data. The following error is displayed:
  warning: dataset </faked and compressed data> cannot be read,
  user defined filter is not available

I believe, the semantics of --filter=NONE should be changed, so that
h5repack will use any filters necessary to read the data, but will write
unfiltered data.

Cheers,
Nathanael
