* Anti-registration of various ABC methods.Guido van Rossum2016-08-181-0/+12
| | | | | | | | | | - Issue #25958: Support "anti-registration" of special methods from various ABCs, like __hash__, __iter__ or __len__. All these (and several more) can be set to None in an implementation class and the behavior will be as if the method is not defined at all. (Previously, this mechanism existed only for __hash__, to make mutable classes unhashable.) Code contributed by Andrew Barnert and Ivan Levkivskyi.

I fixed two bootstrap issues, due to the dynamic import of itertools: 1. Starting python requires that map() and filter() are not used until site.py has added build/lib.<arch> to sys.path. 2. Building python requires that setup.py and distutils and everything they use is free of map() and filter() calls. Beyond this, I only fixed the tests in test_builtin.py. Others, please help fixing the remaining tests that are now broken! The fixes are usually simple: a. map(None, X) -> list(X) b. map(F, X) -> list(map(F, X)) c. map(lambda x: F(x), X) -> [F(x) for x in X] d. filter(F, X) -> list(filter(F, X)) e. filter(lambda x: P(x), X) -> [x for x in X if P(x)] Someone, please also contribute a fixer for 2to3 to do this. It can leave map()/filter() calls alone that are already inside a list() or sorted() call or for-loop. Only in rare cases have I seen code that depends on map() of lists of different lengths going to the end of the longest, or on filter() of a string or tuple returning an object of the same type; these will need more thought to fix. ........ r56136 | guido.van.rossum | 2007-07-01 06:22:01 +0200 (Sun, 01 Jul 2007) | 3 lines Make it so that test_decimal fails instead of hangs, to help automated test runners. ........ r56139 | georg.brandl | 2007-07-01 18:20:58 +0200 (Sun, 01 Jul 2007) | 2 lines Fix a few test cases after the map->imap change. ........ r56142 | neal.norwitz | 2007-07-02 06:38:12 +0200 (Mon, 02 Jul 2007) | 1 line Get a bunch more tests passing after converting map/filter to return iterators. ........ r56147 | guido.van.rossum | 2007-07-02 15:32:02 +0200 (Mon, 02 Jul 2007) | 4 lines Fix the remaining failing unit tests (at least on OSX).

The dict views aren't fully functional yet; in particular, they can't be compared to sets yet. but they are useful as "iterator wells". There are still 27 failing unit tests; I expect that many of these have fairly trivial fixes, but there are so many, I could use help.

* Make built-in zip() equal to itertools.izip().Guido van Rossum2006-08-241-13/+16
| | | | | | | I mea, *really* equal -- for now, the implementation just imports itertools. :-) The only other changes necessary were various unit tests that were assuming zip() returns a real list. No "real" code made this assumption.
* Anna Ravenscroft identified many occurrences of "file" used to open a fileAlex Martelli2006-08-241-2/+2

| | | | | | | | | | | imports e.g. test_support must do so using an absolute package name such as "import test.test_support" or "from test import test_support". This also updates the README in Lib/test, and gets rid of the duplicate data dirctory in Lib/test/data (replaced by Lib/email/test/data). Now Tim and Jack can have at it. :)

* Generalize operator.indexOf (PySequence_Index) to work with anyTim Peters2001-09-081-0/+41
| | | | | | | | | | 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.
* Patch #445762: Support --disable-unicodeMartin v. Löwis2001-08-171-5/+11
| | | | | | | | - Do not compile unicodeobject, unicodectype, and unicodedata if Unicode is disabled - check for Py_USING_UNICODE in all places that use Unicode functions - disables unicode literals, and the builtin functions - add the types.StringTypes list - remove Unicode literals from most tests.

* Generalize zip() to work with iterators.Tim Peters2001-05-061-0/+46
| | | | | | | | NEEDS DOC CHANGES. More AttributeErrors transmuted into TypeErrors, in test_b2.py, and, again, this strikes me as a good thing. This checkin completes the iterator generalization work that obviously needed to be done. Can anyone think of others that should be changed?

* Reimplement PySequence_Contains() and instance_contains(), so they workTim Peters2001-05-051-18/+6
| | | | | | | | | 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.

* Make 'x in y' and 'x not in y' (PySequence_Contains) play nice w/ iterators.Tim Peters2001-05-051-0/+55
| | | | | | | | | | | | | NEEDS DOC CHANGES A few more AttributeErrors turned into TypeErrors, but in test_contains this time. The full story for instance objects is pretty much unexplainable, because instance_contains() tries its own flavor of iteration-based containment testing first, and PySequence_Contains doesn't get a chance at it unless instance_contains() blows up. A consequence is that some_complex_number in some_instance dies with a TypeError unless some_instance.__class__ defines __iter__ but does not define __getitem__.
* Make unicode.join() work nice with iterators. This also required a changeTim Peters2001-05-051-0/+41
| | | | | | | | to string.join(), so that when the latter figures out in midstream that it really needs unicode.join() instead, unicode.join() can actually get all the sequence elements (i.e., there's no guarantee that the sequence passed to string.join() can be iterated over *again* by unicode.join(), so string.join() must not pass on the original sequence object anymore).
* Generalize tuple() to work nicely with iterators.Tim Peters2001-05-051-0/+33
| | | | | | | | | | | | | | | | | | | | | 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.
