Mmm, all the failures comes from the doctest test units. Which Python
interpreter are you using to run the tests? Please can you try plain
Python through:
$ python -c "import tables; tables.test()"
Regarding the second question, you can always access non-Python
identifiers through File.getNode() and File.getNodeAttr() calls. See
this example:
In [1]: import tables
In [2]: f = tables.openFile("/tmp/prova.py", "w")
In [3]: a = f.createArray(f.root, 'node.var', [1,2])
/usr/lib/python2.5/site-packages/tables/path.py:102: NaturalNameWarning:
object name is not a valid Python identifier: 'node.var'; it does not
match the pattern ``^[a-zA-Z_][a-zA-Z0-9_]*$``; you will not be able to
use natural naming to access this object; using ``getattr()`` will
still work, though
NaturalNameWarning )
In [4]: b = f.setNodeAttr(a, 'attr.var', 3)
/usr/lib/python2.5/site-packages/tables/path.py:102: NaturalNameWarning:
object name is not a valid Python identifier: 'attr.var'; it does not
match the pattern ``^[a-zA-Z_][a-zA-Z0-9_]*$``; you will not be able to
use natural naming to access this object; using ``getattr()`` will
still work, though
NaturalNameWarning )
In [5]: a2 = f.getNode('/node.var')
In [6]: f.getNo
f.getNode f.getNodeAttr
In [6]: b2 = f.getNodeAttr(a2, 'attr.var')
In [7]: a2
Out[7]:
/node.var (Array(2,)) ''
atom := Int32Atom(shape=(), dflt=0)
maindim := 0
flavor := 'python'
byteorder := 'little'
chunkshape := None
In [8]: b2
Out[8]: 3
Note that the warnings are a bit confusing (getattr() call doesn't exist
any more). I've filed a ticket about this:
