The following code fails on data files I created yesterday using
pytables (IIRC a daily snapshot just prior to the 1.3 release -- it's
called "1.3beta2"). The h5* tools seem to work (e.g. h5ls, h5dump and so
on). The segfault occurs with pytables 1.2.3, 1.3, and today's svn
current as of now.
I've put a copy of a small (940 KB) example at
http://mosca.caltech.edu/outgoing/DATA20060424_185459.h5
The code that fails is:
import tables
results = tables.openFile('DATA20060424_185459.h5')
for row in results.root.data2d:
print '1'
The segfault happens when trying to get the iterator from the Table
class. (The print statement is never reached.)
This one is a PyTables flaw. I've not a definitive solution for this,
but the attached workaround seems to work well (and it doesn't leak :).
Thanks, indeed the patch allows me to see my data again! :)
I hope you can determine the underlying cause, but I'll happily continue
working with your patch.
