New submission from sds <s...@gnu.org>:
deleting a key from a read-only gdbm should be gdbm.error, not KeyError:
>>> import gdbm
>>> db = gdbm.open("foo","n") # create new
>>> db["a"] = "b"
>>> db.close()
>>> db = gdbm.open("foo","r") # read only
>>> db["x"] = "1"
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
gdbm.error: Reader can't store # correct
>>> db["a"]
'b'
>>> del db["a"]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: 'a' # WRONG! should be the same as above
