===========================
Announcing PyTables 2.4.0b1
===========================

We are happy to announce PyTables 2.4.0b1.

This is an incremental release which includes many changes to prepare
for future Python 3 support.


What's new
==========

This release includes support for the float16 data type and read-only
support for variable length string attributes.

The handling of HDF5 errors has been improved.  The user will no
longer see HDF5 error stacks dumped to the console.  All HDF5 error
messages are trapped and attached to a proper Python exception.

Now PyTables only supports HDF5 v1.8.4+. All the code has been updated
to the new HDF5 API.  Supporting only HDF5 1.8 series is beneficial
for future development.

As always, a large amount of bugs have been addressed and squashed as
well.

In case you want to know more in detail what has changed in this
version, please refer to:
http://pytables.github.com/release_notes.html

You can download a source package with generated PDF and HTML docs, as
well as binaries for Windows, from:
http://sourceforge.net/projects/pytables/files/pytables/2.4.0b1

For an online version of the manual, visit:
http://pytables.github.com/usersguide/index.html


What it is?
===========

PyTables is a library for managing hierarchical datasets and
designed to efficiently cope with extremely large amounts of data with
support for full 64-bit file addressing.  PyTables runs on top of
the HDF5 library and NumPy package for achieving maximum throughput and
convenient use.  PyTables includes OPSI, a new indexing technology,
allowing to perform data lookups in tables exceeding 10 gigarows
(10**10 rows) in less than a tenth of a second.

Acknowledgments
===============

Thanks to many users who provided feature improvements, patches, bug
reports, support and suggestions.  See the ``THANKS`` file in the
distribution package for a (incomplete) list of contributors.  Most
specially, a lot of kudos go to the HDF5 and NumPy (and numarray!)
makers.  Without them, PyTables simply would not exist.

=====================

Let us know of any bugs, suggestions, gripes, kudos, etc. you may have.

Looks good. Only one test failure on win-amd64-py2.7 (attached).

thank you.
This is strange, "HDF5-DIAG" actually is in the output so you should not
have the reported error:

======================================================================
FAIL: test_enable_messages (tables.tests.test_basics.HDF5ErrorHandling)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "X:\Python27-x64\lib\site-packages\tables\tests\common.py", line
259, in newmethod
    return oldmethod(self, *args, **kwargs)
  File "X:\Python27-x64\lib\site-packages\tables\tests\test_basics.py",
line 2445, in test_enable_messages
    self.assertTrue("HDF5-DIAG" in stderr)
AssertionError: False is not true


Looking at the doc is seems that there is no particular issue at
subprocess level.

Umm, can you please check if the message actually comes form the stderr
and not form the stdout?

thanks

[Francesc A. <fa...@gm...>]

Hey Antonio, this looks great.

BTW, which is the status of the 3.x support?  I vaguely remember you 
asking me for some help on this, but I don't remember well. Not that I 
have a lot of time to spend on it, but perhaps I can use some hours in 
the next days.

Thanks,

Francesc

well, in PyTables 2.4 we made some job in preparation of the porting
to python3, but the porting itself is still not started.

One of the main issues is that numexpr still not supports python3 so
we have a missing dependency.

I started a porting of numexpr to python3 (see [1]) but it is still
incomplete.
I hope it is good enough to let us start working on the porting of
PyTables.

Of course if you would like to give a look to numexpr for python3 it
would be of great help.

After the PyTables 2.4 final I plan to publish a wiki page with my
roadmap proposal. IMHO main points are:

* open a new branch in the repo
* remove al deprecated code (Numeric, numarray, netcdf3, etc). This
breaks the API and, IMHO, we will also need to bump the format version
* ensure that all the required SW work (enough) on python3
* handle str/unicode issues
* full support to unicode HDF5 object names
* start working an a good setup for 2to3 (needs some investigation)
* ...

Please let me know if you think there are other point that are
important for python3 support

Ah yes.  I have also tried with the porting of numexpr to python3, but 
failed.  I'll try to have a look at your patches and see if we can make 
it.  Not sure when I'll have time to tackle this, but hopefully I'll be 
able to tell you something soon.

Ok.  That looks good.  This is a lot of work though, but I hope you will 
manage.

Thanks for the fine work!
