Neal Norwitz | 6cf49cf | 2008-03-24 06:22:57 +0000 | [diff] [blame] | 359 | - The dl module was removed, use the ctypes module instead. |

| 365 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 366 | - The class distutils.commands.build_py.build_py_2to3 can be used as a |

Guido van Rossum | f416981 | 2008-03-17 22:56:06 +0000 | [diff] [blame] | 370 | - A new pickle protocol (protocol 3) is added with explicit support |
| 371 | for bytes. This is the default protocol. It intentionally cannot |
| 372 | be unpickled by Python 2.x. |
| 373 | |
| 374 | - When a pickle written by Python 2.x contains an (8-bit) str |
| 375 | instance, this is now decoded to a (Unicode) str instance. The |
| 376 | encoding used to do this defaults to ASCII, but can be overridden |
| 377 | via two new keyword arguments to the Unpickler class. Previously |
| 378 | this would create bytes instances, which is usually wrong: str |
| 379 | instances are often used to pickle attribute names etc., and text is |
| 380 | more common than binary data anyway. |

Martin v. Löwis | 071ef77 | 2008-03-08 11:24:24 +0000 | [diff] [blame] | 382 | - Default to ASCII as the locale.getpreferredencoding, if the POSIX |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 383 | system doesn't support CODESET and LANG isn't set or doesn't allow |

Gregory P. Smith | 425136b | 2008-03-17 20:45:21 +0000 | [diff] [blame] | 388 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 389 | - Issue #719888: Updated tokenize to use a bytes API. generate_tokens |
| 390 | has been renamed tokenize and now works with bytes rather than |
| 391 | strings. A new detect_encoding function has been added for |
| 392 | determining source file encoding according to PEP-0263. Token |
| 393 | sequences returned by tokenize always start with an ENCODING token |
| 394 | which specifies the encoding used to decode the file. This token is |
| 395 | used to encode the output of untokenize back to bytes. |

| 563 | |
Brett Cannon | 37f7e6e | 2007-10-26 05:42:09 +0000 | [diff] [blame] | 564 | - str8 now has the same construction signature as bytes. |
| 565 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 566 | - Comparisons between str and str8 now return False/True for ==/!=. |
| 567 | sqlite3 returns str8 when recreating on object from it's __conform__ |
| 568 | value. The struct module returns str8 for all string-related |
| 569 | formats. This was true before this change, but becomes more |
| 570 | apparent thanks to string comparisons always being False. |
Brett Cannon | 4043001 | 2007-10-22 20:24:51 +0000 | [diff] [blame] | 571 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 572 | - Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode, |

Guido van Rossum | 40d20bc | 2007-10-22 00:09:51 +0000 | [diff] [blame] | 574 | |
| 575 | - Fixed `imp.find_module()` to obey the -*- coding: -*- header. |
| 576 | |
| 577 | - Changed `__file__` and `co_filename` to unicode. The path names are decoded |
Antoine Pitrou | 6e1df8d | 2008-07-25 19:58:18 +0000 | [diff] [blame] | 578 | with `Py_FileSystemDefaultEncoding` and a new API method |
Guido van Rossum | 40d20bc | 2007-10-22 00:09:51 +0000 | [diff] [blame] | 579 | `PyUnicode_DecodeFSDefault(char*)` was added. |
| 580 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 581 | - io.open() and _fileio.FileIO have grown a new argument closefd. A |
| 582 | false value disables the closing of the file descriptor. |
Guido van Rossum | 2dced8b | 2007-10-30 17:27:30 +0000 | [diff] [blame] | 583 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 584 | - Added a new option -b to issues warnings (-bb for errors) about |
| 585 | certain operations between bytes/buffer and str like str(b'') and |
| 586 | comparison. |
Guido van Rossum | 98297ee | 2007-11-06 21:34:58 +0000 | [diff] [blame] | 587 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 588 | - The standards streams sys.stdin, stdout and stderr may be None when |
| 589 | the when the C runtime library returns an invalid file descriptor |
| 590 | for the streams (fileno(stdin) < 0). For now this happens only for |
| 591 | Windows GUI apps and scripts started with `pythonw.exe`. |
Christian Heimes | 58cb1b8 | 2007-11-13 02:19:40 +0000 | [diff] [blame] | 592 | |
Christian Heimes | bce52be | 2007-11-17 19:08:41 +0000 | [diff] [blame] | 593 | - Added PCbuild9 directory for VS 2008. |
| 594 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 595 | - Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to |

Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 598 | - Unbound methods are gone for good. ClassObject.method returns an |
| 599 | ordinary function object, instance.method still returns a bound |
| 600 | method object. The API of bound methods is cleaned up, too. The |
| 601 | im_class attribute is removed and im_func + im_self are renamed to |
| 602 | __func__ and __self__. The factory PyMethod_New takes only func and |
| 603 | instance as argument. |
Christian Heimes | ff73795 | 2007-11-27 10:40:20 +0000 | [diff] [blame] | 604 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 605 | - intobject.h is no longer included by Python.h. The remains were |
| 606 | moved to longobject.h. It still exists to define several aliases |
| 607 | from PyInt_ to PyLong_ functions. |
Christian Heimes | f78b1c6 | 2007-12-02 16:52:32 +0000 | [diff] [blame] | 608 | |

Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 619 | - When loading an external file using testfile(), the passed-in |
| 620 | encoding argument was being ignored if __loader__ is defined and |
| 621 | forcing the source to be UTF-8. |

| 660 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 661 | - Remove the f_restricted attribute from frames. This naturally leads |
| 662 | to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted(). |
Guido van Rossum | a8add0e | 2007-05-14 22:03:55 +0000 | [diff] [blame] | 663 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 664 | - PEP 3132 was accepted. That means that you can do ``a, *b = |
| 665 | range(5)`` to assign 0 to a and [1, 2, 3, 4] to b. |
Guido van Rossum | 0368b72 | 2007-05-11 16:50:42 +0000 | [diff] [blame] | 666 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 667 | - range() now returns an iterator rather than a list. Floats are not |

Georg Brandl | 801dd73 | 2007-03-18 20:18:31 +0000 | [diff] [blame] | 679 | - PEP 3115: new metaclasses: the metaclass is now specified as a |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 680 | keyword arg in the class statement, which can now use the full |
| 681 | syntax of a parameter list. Also, the metaclass can implement a |
| 682 | __prepare__ function which will be called to create the dictionary |
| 683 | for the new class namespace. |

Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 689 | its argument, if it exists. If not, it will work like before. This |
| 690 | allows customizing the output of dir() in the presence of a |
| 691 | __getattr__(). |

Georg Brandl | e32b422 | 2007-03-10 22:13:27 +0000 | [diff] [blame] | 697 | - input() became raw_input(): the name input() now implements the |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 698 | functionality formerly known as raw_input(); the name raw_input() is |

Guido van Rossum | cc2b016 | 2007-02-11 06:12:03 +0000 | [diff] [blame] | 704 | - PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone; |

Guido van Rossum | 8b54536 | 2007-02-09 23:52:14 +0000 | [diff] [blame] | 708 | - PEP 3105: print is now a function. Also (not in the PEP) the |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 709 | 'softspace' attribute of files is now gone (since print() doesn't |
| 710 | use it). A side effect of this change is that you can get |
| 711 | incomplete output lines in interactive sessions: |
Guido van Rossum | 8b54536 | 2007-02-09 23:52:14 +0000 | [diff] [blame] | 712 | |

| 719 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 720 | - Int/Long unification is complete. The 'long' built-in type and |
| 721 | literals with trailing 'L' or 'l' have been removed. Performance |

Guido van Rossum | ab18684 | 2007-01-14 03:42:30 +0000 | [diff] [blame] | 723 | |
| 724 | - 'except E, V' must now be spelled as 'except E as V' and deletes V |

Neal Norwitz | c150536 | 2006-12-28 06:47:50 +0000 | [diff] [blame] | 727 | - Added function annotations per PEP 3107. |
| 728 | |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 729 | - Added nonlocal declaration from PEP 3104: |

Neal Norwitz | 4886cc3 | 2006-08-21 17:06:07 +0000 | [diff] [blame] | 750 | - Classic classes are a thing of the past. All classes are new style. |
| 751 | |
| 752 | - Exceptions *must* derive from BaseException. |
| 753 | |
| 754 | - Integer division always returns a float. The -Q option is no more. |
| 755 | All the following are gone: |
| 756 | * PyNumber_Divide and PyNumber_InPlaceDivide |
| 757 | * __div__, __rdiv__, and __idiv__ |
| 758 | * nb_divide, nb_inplace_divide |
| 759 | * operator.div, operator.idiv, operator.__div__, operator.__idiv__ |
| 760 | (Only __truediv__ and __floordiv__ remain, not sure how to handle them |
| 761 | if we want to re-use __div__ and friends. If we do, it will make |
| 762 | it harder to write code for both 2.x and 3.x.) |
| 763 | |
| 764 | - 'as' and 'with' are keywords. |
| 765 | |
| 766 | - Absolute import is the default behavior for 'import foo' etc. |

Guido van Rossum | cf1be88 | 2007-08-30 22:07:17 +0000 | [diff] [blame] | 779 | - zip(), map() and filter() now return iterators, behaving like their |
Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 780 | itertools counterparts. This also affect map()'s behavior on |
Guido van Rossum | cf1be88 | 2007-08-30 22:07:17 +0000 | [diff] [blame] | 781 | sequences of unequal length -- it now stops after the shortest one |
