* SF patch 419176 from MvL; fixed bug 418977Jeremy Hylton2001-05-082-0/+21
| | | | Two errors in dict_to_map() helper used by PyFrame_LocalsToFast().
* This is a test showing SF bug 422177. It won't trigger until I check inTim Peters2001-05-081-0/+30
| | | | | | another change (to test_import.py, which simply imports the new file). I'm checking this piece in now, though, to make it easier to distribute a patch for x-platform checking.
* Generalize zip() to work with iterators.Tim Peters2001-05-062-2/+48
| | | | | | | | 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?
* Get rid of silly 5am "del" stmts.Tim Peters2001-05-051-2/+0
|
* 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.
* Generalize PySequence_Count() (operator.countOf) to work with iterators.Tim Peters2001-05-051-0/+35
|
* Make 'x in y' and 'x not in y' (PySequence_Contains) play nice w/ iterators.Tim Peters2001-05-052-2/+57
| | | | | | | | | | | | | 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 Peters2001-05-053-6/+39
| | | | | | | | | | | | | | | | | | | | | 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.
* Generalize reduce() to work with iterators.Tim Peters2001-05-041-0/+13
| | | | NEEDS DOC CHANGES.
* Purge redundant cut&paste line.Tim Peters2001-05-031-2/+1
|
* Generalize map() to work with iterators.Tim Peters2001-05-031-0/+35
| | | | | | | | | | | NEEDS DOC CHANGES. Possibly contentious: The first time s.next() yields StopIteration (for a given map argument s) is the last time map() *tries* s.next(). That is, if other sequence args are longer, s will never again contribute anything but None values to the result, even if trying s.next() again could yield another result. This is the same behavior map() used to have wrt IndexError, so it's the only way to be wholly backward-compatible. I'm not a fan of letting StopIteration mean "try again later" anyway.
* Remove redundant copy+paste code.Tim Peters2001-05-031-3/+0

* Generalize list(seq) to work with iterators. This also generalizes list()Tim Peters2001-05-011-0/+32
| | | | | | | | | | | | | to no longer insist that len(seq) be defined. NEEDS DOC CHANGES. This is meant to be a model for how other functions of this ilk (max, filter, etc) can be generalized similarly. Feel encouraged to grab your favorite and convert it! Note some cute consequences: list(file) == file.readlines() == list(file.xreadlines()) list(dict) == dict.keys() list(dict.iteritems()) = dict.items() list(xrange(i, j, k)) == range(i, j, k)
* Fix 2.1 nested scopes crash reported by Evan SimpsonJeremy Hylton2001-04-272-0/+12
| | | | | | | | The new test case demonstrates the bug. Be more careful in symtable_resolve_free() to add a var to cells or frees only if it won't be added under some other rule. XXX Add new assertion that will catch this bug.
* Added more help, and recovery from misspelled sort key arguments.Eric S. Raymond2001-04-261-2/+19

* SF bug 418615: regular expression bug in pipes.py.Tim Peters2001-04-251-4/+4
| | | | | | | | Obviously bad regexps, spotted by Jeffery Collins. HELP! I can't run this on Windows, and the module test() function probably doesn't work on anyone's box. Could a Unixoid please write an at least minimal working test and add it to the std test suite?

* Iterators phase 1. This comprises:Guido van Rossum2001-04-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER new C API PyObject_GetIter(), calls tp_iter new builtin iter(), with two forms: iter(obj), and iter(function, sentinel) new internal object types iterobject and calliterobject new exception StopIteration new opcodes for "for" loops, GET_ITER and FOR_ITER (also supported by dis.py) new magic number for .pyc files new special method for instances: __iter__() returns an iterator iteration over dictionaries: "for x in dict" iterates over the keys iteration over files: "for x in file" iterates over lines TODO: documentation test suite decide whether to use a different way to spell iter(function, sentinal) decide whether "for key in dict" is a good idea use iterators in map/filter/reduce, min/max, and elsewhere (in/not in?) speed tuning (make next() a slot tp_next???)
* dispatcher.__repr__() was unprepared to handle the address for a UnixJeremy Hylton2001-04-201-11/+16

* Implement, test and document "key in dict" and "key not in dict".Guido van Rossum2001-04-201-0/+4
| | | | | | | | | I know some people don't like this -- if it's really controversial, I'll take it out again. (If it's only Alex Martelli who doesn't like it, that doesn't count as "real controversial" though. :-) That's why this is a separate checkin from the iterators stuff I'm about to check in next.
* Weak*Dictionary: Added docstrings to the classes.Fred Drake2001-04-191-24/+36
| | | | | | | | | | | | | | | | Weak*Dictionary.update(): No longer create a temporary list to hold the things that will be stuffed into the underlying dictionary. This had been done so that if any of the objects used as the weakly-held value was not weakly-referencable, no updates would take place (TypeError would be raised). With this change, TypeError will still be raised but a partial update could occur. This is more like other .update() implementations. Thoughout, use of the name "ref" as a local variable has been removed. The original use of the name occurred when the function to create a weak reference was called "new"; the overloaded use of the name could be confusing for someone reading the code. "ref" used as a variable name has been replaced with "wr" (for 'weak reference').
* Fix compileall.py so that it fails on SyntaxErrorsJeremy Hylton2001-04-181-8/+26
| | | | | | | | | | | | | | | | The changes cause compilation failures in any file in the Python installation lib directory to cause the install to fail. It looks like compileall.py intended to behave this way, but a change to py_compile.py and a separate bug defeated it. Fixes SF bug #412436 This change affects the test suite, which contains several files that contain intentional errors. The solution is to extend compileall.py with the ability to skip compilation of selected files. NB compileall.py is changed so that compile_dir() returns success only if all recursive calls to compile_dir() also check success.

| | | | | | | | | | its first return statement returns a single value while its caller always expects it to return a tuple of two items. Fix this by returning (s, 0) instead. This won't make the locale test on Irix succeed, but now it will fail because of a bug in the platform's en_US locale rather than because of a bug in the locale module.
* Change the test data to ask for class C from module __main__ ratherGuido van Rossum2001-04-161-2/+3

* Get rid of the seek() method on the _Mailbox class. This was aGuido van Rossum2001-04-151-8/+0
| | | | | | | | | | | | cut-and-paste copy of the seek() method on the _Subfile class, but it didn't make one bit of sense: it sets self.pos, which is not used in this class or its subclasses, and it uses self.start and self.stop, which aren't defined on this class or its subclasses. This is purely my own fault -- I added this in rev 1.4 and apparently never tried to use it. Since it's not documented, and of very questionable use given that there's no tell(), I'm ripping it out. This resolves SF bug 416199 by Andrew Dalke: mailbox.py seek problems.
