* Patch #1538606, Patch to fix __index__() clipping.Neal Norwitz2006-08-121-3/+17
| | | | | | | I modified this patch some by fixing style, some error checking, and adding XXX comments. This patch requires review and some changes are to be expected. I'm checking in now to get the greatest possible review and establish a baseline for moving forward. I don't want this to hold up release if possible.

| | | | | | | PyObject_CallFunctionObArgs() and PyObject_CallMethodObArgs() have the advantage that no format strings need to be parsed. The CallMethod variant also avoids creating a new string object in order to retrieve a method from an object as well.
* Generalize dictionary() to accept a sequence of 2-sequences. At theTim Peters2001-10-261-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | outer level, the iterator protocol is used for memory-efficiency (the outer sequence may be very large if fully materialized); at the inner level, PySequence_Fast() is used for time-efficiency (these should always be sequences of length 2). dictobject.c, new functions PyDict_{Merge,Update}FromSeq2. These are wholly analogous to PyDict_{Merge,Update}, but process a sequence-of-2- sequences argument instead of a mapping object. For now, I left these functions file static, so no corresponding doc changes. It's tempting to change dict.update() to allow a sequence-of-2-seqs argument too. Also changed the name of dictionary's keyword argument from "mapping" to "x". Got a better name? "mapping_or_sequence_of_pairs" isn't attractive, although more so than "mosop" <wink>. abstract.h, abstract.tex: Added new PySequence_Fast_GET_SIZE function, much faster than going thru the all-purpose PySequence_Size. libfuncs.tex: - Document dictionary(). - Fiddle tuple() and list() to admit that their argument is optional. - The long-winded repetitions of "a sequence, a container that supports iteration, or an iterator object" is getting to be a PITA. Many months ago I suggested factoring this out into "iterable object", where the definition of that could include being explicit about generators too (as is, I'm not sure a reader outside of PythonLabs could guess that "an iterator object" includes a generator call). - Please check my curly braces -- I'm going blind <0.9 wink>. abstract.c, PySequence_Tuple(): When PyObject_GetIter() fails, leave its error msg alone now (the msg it produces has improved since PySequence_Tuple was generalized to accept iterable objects, and PySequence_Tuple was also stomping on the msg in cases it shouldn't have even before PyObject_GetIter grew a better msg).
* Generalize operator.indexOf (PySequence_Index) to work with anyTim Peters2001-09-081-8/+18
| | | | | | | | | | iterable object. I'm not sure how that got overlooked before! Got rid of the internal _PySequence_IterContains, introduced a new internal _PySequence_IterSearch, and rewrote all the iteration-based "count of", "index of", and "is the object in it or not?" routines to just call the new function. I suppose it's slower this way, but the code duplication was getting depressing.
* Implement PEP 238 in its (almost) full glory.Guido van Rossum2001-08-081-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | This introduces: - A new operator // that means floor division (the kind of division where 1/2 is 0). - The "future division" statement ("from __future__ import division) which changes the meaning of the / operator to implement "true division" (where 1/2 is 0.5). - New overloadable operators __truediv__ and __floordiv__. - New slots in the PyNumberMethods struct for true and floor division, new abstract APIs for them, new opcodes, and so on. I emphasize that without the future division statement, the semantics of / will remain unchanged until Python 3.0. Not yet implemented are warnings (default off) when / is used with int or long arguments. This has been on display since 7/31 as SF patch #443474. Flames to /dev/null.

* Reimplement PySequence_Contains() and instance_contains(), so they workTim Peters2001-05-051-1/+11
| | | | | | | | | safely together and don't duplicate logic (the common logic was factored out into new private API function _PySequence_IterContains()). Visible change: some_complex_number in some_instance no longer blows up if some_instance has __getitem__ but neither __contains__ nor __iter__. test_iter changed to ensure that remains true.
* Generalize tuple() to work nicely with iterators.Tim Peters2001-05-051-1/+1
| | | | | | | | | | | | | | | | | | | | | 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.
* Make PyIter_Next() a little smarter (wrt its knowledge of iteratorTim Peters2001-05-051-3/+2
| | | | internals) so clients can be a lot dumber (wrt their knowledge).
* Mondo changes to the iterator stuff, without changing how Python codeGuido van Rossum2001-04-231-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | sees it (test_iter.py is unchanged). - Added a tp_iternext slot, which calls the iterator's next() method; this is much faster for built-in iterators over built-in types such as lists and dicts, speeding up pybench's ForLoop with about 25% compared to Python 2.1. (Now there's a good argument for iterators. ;-) - Renamed the built-in sequence iterator SeqIter, affecting the C API functions for it. (This frees up the PyIter prefix for generic iterator operations.) - Added PyIter_Check(obj), which checks that obj's type has a tp_iternext slot and that the proper feature flag is set. - Added PyIter_Next(obj) which calls the tp_iternext slot. It has a somewhat complex return condition due to the need for speed: when it returns NULL, it may not have set an exception condition, meaning the iterator is exhausted; when the exception StopIteration is set (or a derived exception class), it means the same thing; any other exception means some other error occurred.
* Iterators phase 1. This comprises:Guido van Rossum2001-04-201-0/+5

* Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in eitherThomas Wouters2000-07-161-1/+1
| | | | | | | | | | comments, docstrings or error messages. I fixed two minor things in test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't"). There is a minor style issue involved: Guido seems to have preferred English grammar (behaviour, honour) in a couple places. This patch changes that to American, which is the more prominent style in the source. I prefer English myself, so if English is preferred, I'd be happy to supply a patch myself ;)
