Hello list,
If you obtain a row iterator and then try to access a nonexistent column, it
should presumably raise a KeyError or something similar. Instead it gives a
TypeError when trying to raise an exception. Here's a script to reproduce
the problem:
import sys
from tables import openFile
f = openFile(sys.argv[1])
table = f.getNode(sys.argv[2])
# This works
row = table[0]
assert not 'nonexistent_col' in row
# This doesn't
row = [r for r in table.iterrows(0, 1)][0]
assert not 'nonexistent_col' in row
f.close()
And here's the result I get when I run the above script on a valid PyTables
H5 file:
ctkr...@ctkrohn-bigthink:~/Code/pytables_bug$ ./pytables_bug.py
../fcr/h5/comp.h5 /t102010
Traceback (most recent call last):
File "./pytables_bug.py", line 15, in <module>
assert not 'nonexistent_col' in row
File "tableExtension.pyx", line 1296, in
tables.tableExtension.Row.__contains__
TypeError: raise: exception class must be a subclass of BaseException
Closing remaining open files: ../fcr/h5/comp.h5... done
Is this expected behavior? FYI I'm using 2.2pro.
