NEEDS DOC CHANGES. This one surprised me! While I expected tuple() to be a no-brainer, turns out it's actually dripping with consequences: 1. It will *allow* the popular PySequence_Fast() to work with any iterable object (code for that not yet checked in, but should be trivial). 2. It caused two std tests to fail. This because some places used PyTuple_Sequence() (the C spelling of tuple()) as an indirect way to test whether something *is* a sequence. But tuple() code only looked for the existence of sq->item to determine that, and e.g. an instance passed that test whether or not it supported the other operations tuple() needed (e.g., __len__). So some things the tests *expected* to fail with an AttributeError now fail with a TypeError instead. This looks like an improvement to me; e.g., test_coercion used to produce 559 TypeErrors and 2 AttributeErrors, and now they're all TypeErrors. The error details are more informative too, because the places calling this were *looking* for TypeErrors in order to replace the generic tuple() "not a sequence" msg with their own more specific text, and AttributeErrors snuck by that. |
