[Pytables-users] Help on testing PyTables 0.9

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

Hi,

I'm in the final phase of testing PyTables 0.9 before releasing it. As the
number of supported platforms is increasing, I'm asking for your help here.

As of now, I've successfully tested PyTables mainly with Linux machines,
both 32-bits (Pentium IV) and 64-bits (Intel Itanium, AMD Opteron). However,
I would like to test, at very least, the Windows and MacOSX implementation.
If someone is able to test a BSD, Solaris or Irix platforms, much better :)

The procedure of compilation/installation has not been updated in
documentation yet, but it should be fairly similar to 0.8.1. You should be
able to run PyTables with both HDF5 1.6.2 and HDF5 1.6.3-post1, and either
numarray 1.0 or numarray 1.1 (although I've recently only tested numarray
1.1). 

You can find the 0.9 pre-release in:

http://pytables.sourceforge.net/html/GetIt.html

and clicking in "Preview of the forthcoming 0.9 release"

Please, have in mind that the new "official" version of HDF5, namely 1.6.3,
version came out with a nasty bug that prevents to delete an Index object
(which has been introduced in PyTables 0.9) and besides, it causes a
segmentation fault if you try to do that. I've asked to the NCSA to provide
binary libraries with that bug corrected (the -post1 version), and they are
willing to do that, at least for Windows and MacOSX platforms. So, any user
on Win or MacOSX can test HDF5 1.6.3-post1 binaries as well? I'm attaching
below the message from Elena Pourmal (the Maintenance and Support Team
Leader) with the location for these libraries and asking for confirmation
that the libraries works well.

One thing more, a Windows user has already told me that he is having
problems with the newly introduced calls to nextafter and nextafterf
mathematical functions that appear not to be on "math.h", which is the
official place in C99 standard. Someone can provide a patch for this (using
the Microsoft C Library)?.

Many thanks for your time!

Francesc,

I've built binaries with applied path for Windows, Linux 2.4 and Mac OSX. 
Binaries are not configured with szip support but gzip support is included.

Files are on our ftp server in my outgoing directory:

ftp://hdf.ncsa.uiuc.edu/pub/outgoing/epourmal/patch

Could you please test at least one binary distribution and make sure it 
works for you?
If it works, we will move the files to our official distribution site and 
we will let you know the exact location.

If you want to build from scratch yourself, just drop H5Distore.c file into 
the src directory of the hdf5-1.6.3 source.

Thank you!

Elena
