95
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000096- Issue #5829: complex("1e500") no longer raises OverflowError. This
97 makes it consistent with float("1e500") and interpretation of real

108 (1) inf and nan strings with trailing whitespace were incorrectly
109 rejected; (2) parsing of strings representing infinities and nans
110 was locale aware; and (3) the interpretation of fromhex('-nan')
111 didn't match that of float('-nan').
112
Eric Smitha985a3a2009-05-05 18:26:08 +0000113- Issue #5920: For float.__format__, change the behavior with the
114 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
115 to be like 'g' but with at least one decimal point and with a
116 default precision of 12. Previously, the behavior the same but with
117 a default precision of 6. This more closely matches str(), and
118 reduces surprises when adding alignment flags to the empty
119 presentation type. This also affects the new complex.__format__ in
120 the same way.
121
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000122- Issue #5890: in subclasses of 'property' the __doc__ attribute was

131
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000132- Issue #5864: Fix empty format code formatting for floats so that it

147 z involves nans, infs or negative zeros.
148
Eric Smithaca19e62009-04-22 13:29:05 +0000149- Implement PEP 378, Format Specifier for Thousands Separator, for
150 floats, ints, and longs.
151
152- Issue #5515: 'n' formatting for ints, longs, and floats handles
153 leading zero formatting poorly.

162 some builtin types.
163
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000164- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000165 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000166
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000167- Issue #5759: float() didn't call __float__ on str subclasses.

Antoine Pitrouf8387af2009-03-23 18:41:45 +0000184- Issue #4688: Add a heuristic so that tuples and dicts containing only
185 untrackable objects are not tracked by the garbage collector. This can
186 reduce the size of collections and therefore the garbage collection overhead
187 on long-running programs, depending on their particular use of datatypes.
188
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000189- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

192
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000193- Issue #4258: Make it possible to use base 2**30 instead of base
194 2**15 for the internal representation of integers, for performance
195 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
196 --enable-big-digits option to configure, which overrides the
197 default. Add sys.long_info structseq to provide information about
198 the internal format.
199
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000200- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
201 result traceback.__members__ no longer exists.)
202
Mark Dickinson6b265f12009-03-18 16:07:26 +0000203- Issue #4474: PyUnicode_FromWideChar now converts characters outside
204 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
205 and sizeof(Py_UNICODE) == 2.
206
Eric Smith6f42edb2009-03-14 11:57:26 +0000207- Issue #5237: Allow auto-numbered fields in str.format(). For
208 example: '{} {}'.format(1, 2) == '1 2'.
209
Brett Cannon6c4cff02009-03-11 04:51:06 +0000210- Issue #3652: Make the 'line' argument for warnings.showwarning() a
211 requirement. Means the DeprecationWarning from Python 2.6 can go away.
212
Eric Smithe9fb6862009-02-20 14:02:36 +0000213- Issue #5247: Improve error message when unknown format codes are

218 for ints and longs.
219
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000220- Issue #5260: Long integers now consume less memory: average
221 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
222 on a 64-bit system.
223
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000224- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
225 rotating the object pointer by 4 bits to the right.
226
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000227- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:

229
Benjamin Petersone18ef192009-01-20 14:21:16 +0000230- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
231
Georg Brandl29c6a282009-04-05 20:23:13 +0000232- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000233 were suppressing all exceptions. These include list(), filter(), map(),
234 zip(), and bytearray().
235
Benjamin Peterson596d3062009-01-19 15:42:23 +0000236- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

264 an existing .py counterpart, override the co_filename attributes of all
265 code objects if the original filename is obsolete (which can happen if the
266 file has been renamed, moved, or if it is accessed through different paths).
267 Patch by Ziga Seilnacht and Jean-Paul Calderone.

302 context manager returns a value that cannot be converted to a bool.
303
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000304- Issue #4597: Fixed several opcodes that weren't always propagating
305 exceptions.
306
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000307- Issue #4445: Replace "sizeof(PyStringObject)" with
308 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
309 str instances. On a typical machine this saves 3 bytes of memory
310 (on average) per string allocation.
311
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000312- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
313 interpreter to abort ("Fatal Python error: Could not reset the stack!")
314 instead of throwing a MemoryError.
315
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000316- Issue #3689: The list reversed iterator now supports __length_hint__

318
Benjamin Petersonc078f922008-11-21 22:27:24 +0000319- Issue #4367: Python would segfault during compiling when the unicodedata
320 module couldn't be imported and \N escapes were present.
321
Vinay Sajip213faca2008-12-03 23:22:58 +0000322- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000323 method on file objects with closefd=False. The file descriptor is still
324 kept open but the file object behaves like a closed file. The ``FileIO``
325 object also got a new readonly attribute ``closefd``.
326
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000327- Issue #4348: Some bytearray methods returned that didn't cause any change to
328 the bytearray, returned the same bytearray instead of a copy.
329
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000330- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

340 method does not return iterators for the 4th and 5th items.
341
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000342- Issue #4209: Enabling unicode_literals and the print_function in the same
343 __future__ import didn't work.
344
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000345- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000346 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000347
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000348- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
349 returned a path longer than MAX_PATH. (But It's doubtful this code path is
350 really executed because I cannot move to such directory on win2k)
351
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000352- Issue #4069: When set.remove(element) is used with a set element, the element
353 is temporarily replaced with an equivalent frozenset. But the eventual
354 KeyError would always report the empty frozenset([]) as the missing key. Now
355 it correctly refers to the initial element.
356
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000357- Issue #4509: Various issues surrounding resize of bytearray objects to

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000372- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
373 returned them on 64bit platforms.
374
Walter Dörwalded960ac2009-05-03 22:36:33 +0000375- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
376 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
377 step. This avoids problems with counting UTF-8 bytes that ignores the effect
378 of using the replace error handler in PyUnicode_DecodeUTF8().
379
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000380- Issue #3739: The unicode-internal encoder now reports the number of characters
381 consumed like any other encoder (instead of the number of bytes).

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001545- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1546
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001547- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1548 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1549 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1550 ``printf`` function, whereas PyString_FromFormat has an independent
1551 implementation and uses "%zd" on all platforms for size_t values.
1552 This makes a difference on win64, where ``printf`` needs "%Id" to display
1553 64bit values.
1554
Benjamin Peterson97179b02008-09-09 20:55:01 +00001555- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1559 object; previously an int would be returned for small values. the __long__
1560 method is allowed to return either an int or a long, but the behaviour of
1561 float objects should not change to respect backward compatibility.
1562
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001563- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001569 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001570 was correctly parsed but parsing of subsequent arguments failed.
1571
Vinay Sajip35e3b032008-09-01 14:33:59 +00001572- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001573 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1574 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1575 when given a tuple of classes as second argument, were looking up
1576 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1577 type object.
1578
Neal Norwitz18aa3882008-08-24 05:04:52 +00001579- Fix crashes on memory allocation failure found with failmalloc.
1580
1581- Fix memory leaks found with valgrind and update suppressions file.
1582
1583- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001716What's New in Python 2.6 beta 3?
1717================================
1718
Barry Warsaw07a4a382008-08-21 01:15:08 +00001719*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001720
1721Core and Builtins
1722-----------------
1723
Guido van Rossumf8402962008-08-20 15:01:50 +00001724- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1725 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1726 extensions do not automatically benefit from the class attribute
1727 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1728 to their tp_flags field if they care. This is a backwards
1729 compatibility feature; in 3.0, all types will use the cache by
1730 default.
1731
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001732- Keyword arguments can now follow starred arguments. (``f(a, *args,
1733 keyword=23)`` is now valid syntax.)
1734
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001735- ctypes function pointers that are COM methods have a boolean True
1736 value again.
1737
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001738- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1739 by denying s# to parse objects that have a releasebuffer procedure,
1740 and introducing s*.
1741
Georg Brandl1e13ea92008-08-11 09:07:59 +00001742- Issue #3537: Fix an assertion failure when an empty but presized dict
1743 object was stored in the freelist.
1744
Mark Dickinsonb6467572008-08-04 21:30:09 +00001745- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1746 ValueError consistently across platforms.
1747
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001748- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1749 (64bit Unix, for example), unichr() would truncate its argument and return
1750 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1751
Neal Norwitze7d8be82008-07-31 17:17:14 +00001752- Apply security patches from Apple.
1753
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001754- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1755 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1756
Antoine Pitrou92f82162008-07-25 22:22:08 +00001757- Issue #1819: function calls with several named parameters are now on
1758 average 35% faster (as measured by pybench).
1759
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001760- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1761 the python debugger steps into a class statement: the free variables (local
1762 variables defined in an outer scope) would be deleted from the outer scope.
1763
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001764- Issue #2620: Overflow checking when allocating or reallocating memory
1765 was not always being done properly in some python types and extension
1766 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1767 all been updated to perform better checks and places in the code that
1768 would previously leak memory on the error path when such an allocation
1769 failed have been fixed.
1770
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001771Library
1772-------
1773
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001774- Issue #3612: Added some missing basic types in ctypes.wintypes.
1775
Benjamin Petersone977ad42008-08-20 01:42:01 +00001776- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1777 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1778
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001779- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1780 version reported by these tools does not necessarily follow the python
1781 version numbering scheme, so the module is less strict when parsing it.
1782
Nick Coghlanf70385a2008-08-18 12:42:46 +00001783- Issue #2235: Added Py3k warnings for types which will become unhashable
1784 under the stricter __hash__ inheritance rules in 3.0. Several types
1785 which did not meet the rules for hash invariants and were already
1786 unhashable in 3.0 have now been explicitly flagged as unhashable in
1787 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1788 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1789
Brett Cannon88f801d2008-08-18 00:46:22 +00001790- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1791 imported into the module but exposed as part of the module's API.
1792
Brett Cannon7b96f072008-08-18 00:41:11 +00001793- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1794
Brett Cannon46225e72008-08-18 00:36:52 +00001795- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1796
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001797- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1798
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001799- Issue #3575: Incremental decoder's decode function now takes bytearray
1800 by using 's*' instead of 't#'.
1801
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001802- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001803 fails unicode conversion on 2nd parameter. (windows only)
1804
Facundo Batista94f243a2008-08-17 03:38:39 +00001805- Issue 2464. urllib2 now supports a malformation in the URL received
1806 in a redirect.
1807
Brett Cannonabe423e2008-08-16 21:47:07 +00001808- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001809 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001810
Facundo Batistaeb90b782008-08-16 14:44:07 +00001811- Issue #2776: fixed small issue when handling an URL with double slash
1812 after a 302 response in the case of not going through a proxy.
1813
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001814- Issue #2676: in the email package, content-type parsing was hanging on
1815 pathological input because of quadratic or exponential behaviour of a
1816 regular expression.
1817
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001818- Issue #3476: binary buffered reading through the new "io" library is now
1819 thread-safe.
1820
Brett Cannonbf3157b2008-08-14 05:00:03 +00001821- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1822 since mimetools itself is deprecated. Because modules are cached, all
1823 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1824
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001825- Issue #3134: shutil referenced undefined WindowsError symbol.
1826
Robert Schuppenies14646332008-08-10 11:01:53 +00001827- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1828 menu entries were not deleted.
1829
Brett Cannon83e81842008-08-09 23:30:55 +00001830- Copied the implementation of reduce() to _functools.reduce() to have a
1831 version that did not raise a DeprecationWarning under -3.
1832
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001833- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1834 a MemoryError rather than silently stop the iteration.
1835
Guido van Rossum59ce9012008-08-09 14:55:34 +00001836- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1837 to _sre.compile() will now be rejected. This should not affect anybody
1838 since the re.compile() function never generates invalid re-bytecode.
1839
Skip Montanaroa032bf42008-08-08 22:52:51 +00001840- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1841 upon first access it can be automatically initialized from the csv file if
1842 it wasn't initialized during instantiation.
1843
Brett Cannon3aa2a492008-08-06 22:28:09 +00001844- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1845 the reload() built-in has been removed.
1846
Brett Cannon7e30b672008-08-04 21:52:25 +00001847- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001848 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001849 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1850 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1851 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1852 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1853 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001854
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001855- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1856 raised an AttributeError.
1857
Benjamin Peterson01a24322008-07-28 23:35:27 +00001858- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001859 asking for a specific length. This problem only affected files opened
1860 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001861
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001862- Issue #3449: Update decimal module to use most recent specification
1863 (v. 1.68) and tests (v. 2.58) from IBM.
1864
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001865- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1866
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001867- Issue 1592: Improve error reporting when operations are attempted
1868 on a closed shelf.

1871
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001872- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1873
1874- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1875 invalid arguments.
1876
1877- Issue #3302: Fix several crashes when calling locale's gettext functions
1878 with None arguments.
1879
1880- Issue #3389: Allow resolving dotted names for handlers in logging
1881 configuration files.
1882
1883- Deprecate the sunaudio module for removal in Python 3.0.
1884
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001885- Issue #3394: zipfile.writestr sets external attributes when passed a
1886 file name rather than a ZipInfo instance, so files are extracted with
1887 mode 0600 rather than 000 under Unix.
1888
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001889- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1890 argument in python 2.5, this broke code that subclassed Popen to include its
1891 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1899-------------
1900
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001901- Issue #2235: the C API function PyObject_HashNotImplemented and its
1902 interaction with the tp_hash slot (added in 2.6b2) are now documented
1903
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001904- Issue #643841: The language reference now provides more detailed
1905 coverage of the lookup process for special methods. The disclaimers
1906 regarding lack of coverage of new-style classes have also been
1907 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001910What's New in Python 2.6 beta 2?
1911================================
1912
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001913*Release date: 17-Jul-2008*
1914
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001915Core and Builtins
1916-----------------
1917
Georg Brandl3e483f62008-07-16 22:57:41 +00001918- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1919 its methods now allow for items objects that can be converted to
1920 an integer using operator.index().
1921
Mark Dickinson64b7e502008-07-16 09:40:03 +00001922- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1923 produced a ValueError instead of giving the correct float.
1924
Eric Smitha5fa5a22008-07-16 00:11:49 +00001925- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1926 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1927
Mark Dickinson7103aa42008-07-15 19:08:33 +00001928- Issue #3008: the float type has a new instance method 'float.hex'
1929 and a new class method 'float.fromhex' to convert floating-point
1930 numbers to and from hexadecimal strings, respectively.
1931
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001932- Issue #2235: __hash__ is once again inherited by default. To allow
1933 collections.Hashable to remain meaningful in the presence of the
1934 default hash implementation (object.__hash__), it is now possible
1935 to explicit block inheritance of hash by setting __hash__=None at
1936 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1937 level.
1938
Nick Coghlanb028f502008-07-13 14:52:36 +00001939- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1940 the parent module cannot be found while performing an absolute import.
1941 This means that an incorrectly defined __package__ attribute will
1942 now only prevent relative imports in that module rather than causing
1943 all imports from that module to fail.
1944
Nick Coghlan14ff9942008-07-08 14:21:42 +00001945- Issue #2517: Allow unicode messages in Exceptions again by correctly
1946 bypassing the instance dictionary when looking up __unicode__ on
1947 new-style classes.
1948
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001949- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1950 set to a custom object whose write() method happens to install
1951 another file in sys.stdout.
1952
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001953- Issue #3088: Corrected a race condition in classes derived from
1954 threading.local: the first member set by a thread could be saved in
1955 another thread's dictionary.
1956
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001957- Issue #3004: Minor change to slice.indices(): the start and stop
1958 arguments are now treated identically, making the behaviour easier
1959 to describe and understand. For example, slice(None, -10,
1960 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1961 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1962 10, -1).
1963
Georg Brandl278fc502008-07-19 12:46:12 +00001964- Issue #3219: Calling a function with repeated keyword arguments,
1965 f(a=2, a=23), would not cause a syntax error. This was a regression
1966 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001967
Georg Brandl278fc502008-07-19 12:46:12 +00001968- Issue #2862: Make int and float freelist management consistent with
1969 other freelists. Changes their CompactFreeList apis into
1970 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001971

1974
Thomas Heller57adf222008-08-14 19:10:48 +00001975- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1976 api functions without holding the GIL, which could lead to a fatal
1977 error when they failed.
1978
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001979- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001987- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1988 ForkingPickler.register() to resolve conflict with ctypes.
1989
Vinay Sajip51e65192008-07-18 09:01:10 +00001990- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

1993 a valid dlerror() message.
1994
Thomas Heller2bad6572008-07-15 17:19:50 +00001995- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1996 incomplete structure was created.
1997
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001998- Issue #3339: dummy_thread.acquire() should not return None.
1999
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002000- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2001

2413
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002414- On MacOS X it is now possible to install the framework in 64-bit
2415 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002416 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002417
2418 This is controlled by the configure argument ``--with-universal-archs``:
2419
2420 - ``--with-universal-archs=all``: install 4-way universal
2421
2422 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2423
2424 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2425
2426 This option should be used in combination with ``--enable-universalsdk=``.
2427
2428 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2465 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00002466
Christian Heimese74c8f22008-04-19 02:23:57 +00002467- Added kill, terminate and send_signal(sig) to subprocess.Popen.
2468
Georg Brandl3ee81df2008-05-17 18:14:43 +00002469- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
2470 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00002471

Georg Brandl3ee81df2008-05-17 18:14:43 +00002478- Issue #1631171: Re-implement the 'warnings' module in C (the
2479 original Python code has been kept as backup). This will allow for
2480 using the 'warning's machinery in such places as the parser where
2481 use of pure Python code is not possible. Both the ``showarning()``
2482 and ``formatwarning()`` gain an optional 'line' argument which is
2483 not called by default for backwards-compatibility reasons. Setting
2484 ``warnings.showwarning()`` to an implementation that lacks support
2485 for the ``line`` argument will raise a DeprecationWarning.

Thomas Hellerbf027c42008-04-24 18:14:19 +00002508 reference to themselves.
2509
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002510- The getpass module has been improved on Unix. It now uses /dev/tty
2511 by default and uses stderr instead of stdout. A GetPassWarning is
2512 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002513

Georg Brandl3ee81df2008-05-17 18:14:43 +00002527- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002528 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002548- Issue #2550: The approach used by client/server code for obtaining
2549 ports to listen on in network-oriented tests has been refined in an
2550 effort to facilitate running multiple instances of the entire
2551 regression test suite in parallel without issue.
2552 test_support.bind_port() has been fixed such that it will always
2553 return a unique port -- which wasn't always the case with the
2554 previous implementation, especially if socket options had been set
2555 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2556 new implementation of bind_port() will actually raise an exception
2557 if it is passed an AF_INET/SOCK_STREAM socket with either the
2558 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2559 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2560 the socket it's been passed. This currently only applies to
2561 Windows. This option prevents any other sockets from binding to the
2562 host/port we've bound to, thus removing the possibility of the
2563 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2564 when a second SOCK_STREAM socket binds and accepts to a host/port
2565 that's already been bound by another socket. The optional preferred
2566 port parameter to bind_port() has been removed. Under no
2567 circumstances should tests be hard coding ports!
2568
2569 test_support.find_unused_port() has also been introduced, which will
2570 pass a temporary socket object to bind_port() in order to obtain an
2571 unused port. The temporary socket object is then closed and
2572 deleted, and the port is returned. This method should only be used
2573 for obtaining an unused port in order to pass to an external program
2574 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2575 a parameter to a server-oriented class that doesn't give you direct
2576 access to the underlying socket used.
2577
2578 Finally, test_support.HOST has been introduced, which should be used
2579 for the host argument of any relevant socket calls (i.e. bind and
2580 connect).

2854Core and builtins
2855-----------------
2856
Fred Drakea8ee94b2008-03-01 02:45:07 +00002857- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002858 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002859
Georg Brandlad61bc82008-02-23 15:11:18 +00002860- Issue #2067: file.__exit__() now calls subclasses' close() method.
2861
2862- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002863
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002864- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002865 issue 215555 for a discussion.
2866
Eric Smitha73fbe72008-02-23 03:09:44 +00002867- Added the future_builtins module, which contains hex() and oct().
2868 These are the PEP 3127 version of these functions, designed to be
2869 compatible with the hex() and oct() builtins from Python 3.0. They
2870 differ slightly in their output formats from the existing, unchanged
2871 Python 2.6 builtins. The expected usage of the future_builtins
2872 module is:
2873 from future_builtins import hex, oct
2874
Eric Smith7ef40bf2008-02-20 23:34:22 +00002875- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2876 exponents for exponents with absolute value < 100. Follows C99
2877 standard. This is a change on Windows, which would use 3 digits.
2878 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2879 so that any alterations it does to the resulting string will be
2880 available in stringlib/formatter.h (for float.__format__).
2881
Eric Smith5a3c1352008-02-19 13:21:56 +00002882- Implemented PEP 3101, Advanced String Formatting. This adds a new
2883 builtin format(); a format() method for str and unicode; a
2884 __format__() method to object, str, unicode, int, long, float, and
2885 datetime; the class string.Formatter; and the C API
2886 PyObject_Format().
2887
Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Fixed several potential crashes, all caused by specially crafted
2889 __del__ methods exploiting objects in temporarily inconsistent
2890 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002891
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002892- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002893 prevent a possible crash: an Abstract Base Class would try to access
2894 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002895
Georg Brandl3ee81df2008-05-17 18:14:43 +00002896- Fixed repr() and str() of complex numbers with infinity or nan as
2897 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002898
Georg Brandl3ee81df2008-05-17 18:14:43 +00002899- Clear all free lists during a gc.collect() of the highest generation
2900 in order to allow pymalloc to free more arenas. Python may give back
2901 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002902
Georg Brandl3ee81df2008-05-17 18:14:43 +00002903- Issue #2045: Fix an infinite recursion triggered when printing a
2904 subclass of collections.defaultdict, if its default_factory is set
2905 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002906
Christian Heimesf75dbef2008-02-08 00:11:31 +00002907- Fixed a minor memory leak in dictobject.c. The content of the free
2908 list was not freed on interpreter shutdown.
2909
Georg Brandl3ee81df2008-05-17 18:14:43 +00002910- Limit free list of method and builtin function objects to 256
2911 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002912
Georg Brandl3ee81df2008-05-17 18:14:43 +00002913- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2914 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002915 to compact the internal free lists of pre-allocted ints and floats.
2916
Georg Brandl3ee81df2008-05-17 18:14:43 +00002917- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2918 calls. Python expected the return type int but the fork familie
2919 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002920
Georg Brandl3ee81df2008-05-17 18:14:43 +00002921- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2922 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002923
Georg Brandl3ee81df2008-05-17 18:14:43 +00002924- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2925 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002926
Georg Brandl3ee81df2008-05-17 18:14:43 +00002927- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2928 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002929
Georg Brandl3ee81df2008-05-17 18:14:43 +00002930- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2931 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002932
Georg Brandl3ee81df2008-05-17 18:14:43 +00002933- Patch #1473257: generator objects gain a gi_code attribute. This is
2934 the same object as the func_code attribute of the function that
2935 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002936
Georg Brandl3ee81df2008-05-17 18:14:43 +00002937- Issue #1920: "while 0" statements were completely removed by the
2938 compiler, even in the presence of an "else" clause, which is
2939 supposed to be run when the condition is false. Now the compiler
2940 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002941
Guido van Rossumeead05f2008-01-24 18:21:02 +00002942- A few crashers fixed: weakref_in_del.py (issue #1377858);
2943 loosing_dict_ref.py (issue #1303614, test67.py);
2944 borrowed_ref_[34].py (not in tracker).
2945
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002946- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002947 suppressed while an extension is loaded by calling SetErrorMode in
2948 dynload_win.c. The error is still reported properly.
2949
Georg Brandl3ee81df2008-05-17 18:14:43 +00002950- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002951 several extension methods and modules do not work without unicode
2952 support.
2953
Georg Brandl26543b12008-01-21 18:36:51 +00002954- Issue #1882: when compiling code from a string, encoding cookies in the
2955 second line of code were not always recognized correctly.
2956
Georg Brandl14404b62008-01-19 19:27:05 +00002957- Issue #1679: "0x" was taken as a valid integer literal.
2958
Georg Brandl6caad7d2008-01-26 14:19:22 +00002959- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002960 added.
2961
Christian Heimesc94e2b52008-01-14 04:13:37 +00002962- sys.float_info / PyFloat_GetInfo: The floating point information
2963 object was converted from a dict to a specialized structseq object.
2964
Georg Brandl3ee81df2008-05-17 18:14:43 +00002965- Patch #1816: Added sys.flags structseq. It exposes the status of
2966 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002967
Georg Brandl3ee81df2008-05-17 18:14:43 +00002968- Objects/structseq.c: Implemented new structseq representation. The
2969 patch makes structseqs (e.g. the return value of os.stat) more
2970 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002971
Georg Brandl3ee81df2008-05-17 18:14:43 +00002972- Patch #1700288: added a type attribute cache that caches method
2973 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002974
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002975- Bug #1776: __import__() no longer accepts filenames on any platform.
2976 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002977
Georg Brandlaed6c662008-01-07 17:25:53 +00002978- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2979
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2981 envvar and sys.dont_write_bytecode attribute. All these can be set
2982 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002983
Georg Brandl3ee81df2008-05-17 18:14:43 +00002984- Improve some exception messages when Windows fails to load an
2985 extension module. Now we get for example '%1 is not a valid Win32
2986 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002987
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002990- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2991 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002992
Christian Heimes0a8143f2007-12-18 23:22:54 +00002993- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002994 and INF. float("nan"), float("inf") and float("-inf") now work on
2995 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002996
Georg Brandl3ee81df2008-05-17 18:14:43 +00002997- Compiler now generates simpler and faster code for dictionary
2998 literals. The oparg for BUILD_MAP now indicates an estimated
2999 dictionary size. There is a new opcode, STORE_MAP, for adding
3000 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003001
Georg Brandl3ee81df2008-05-17 18:14:43 +00003002- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003004- Issue #1620: New property decorator syntax was modifying the
3005 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003006
Georg Brandl3ee81df2008-05-17 18:14:43 +00003007- Issue #1538: Avoid copying string in split/rsplit if the split char
3008 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003009
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003010- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003011 SystemError.
3012
Nick Coghlanef01d822007-12-03 12:55:17 +00003013- PEP 366: Allow explicit relative imports when executing modules
3014 inside packages with the -m switch via a new module level
3015 __package__ attribute.
3016
Georg Brandl3ee81df2008-05-17 18:14:43 +00003017- Issue #1402: Fix a crash on exit, when another thread is still
3018 running, and if the deallocation of its frames somehow calls the
3019 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003020

3030 file can now be directly executed by passing their name to the
3031 interpreter. The directory/zipfile is automatically inserted as the
3032 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003033
Georg Brandl3ee81df2008-05-17 18:14:43 +00003034- Issue #1265: Fix a problem with sys.settrace, if the tracing
3035 function uses a generator expression when at the same time the
3036 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003037
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003038- sets and frozensets now have an isdisjoint() method.
3039
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003040- optimize the performance of builtin.sum().
3041
Neal Norwitz44f326e2007-10-05 05:29:17 +00003042- Fix warnings found by the new version of the Coverity checker.
3043
Georg Brandl3ee81df2008-05-17 18:14:43 +00003044- The enumerate() builtin function is no longer bounded to sequences
3045 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3046 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003047
Georg Brandl3ee81df2008-05-17 18:14:43 +00003048- Issue #1686386: Tuple's tp_repr did not take into account the
3049 possibility of having a self-referential tuple, which is possible
3050 from C code. Nor did object's tp_str consider that a type's tp_str
3051 could do something that could lead to an inifinite recursion.
3052 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3053 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003054
Georg Brandl3ee81df2008-05-17 18:14:43 +00003055- Issue #1164: It was possible to trigger deadlock when using the
3056 'print' statement to write to a file since the GIL was not released
3057 as needed. Now PyObject_Print() does the right thing along with
3058 various tp_print implementations of the built-in types and those in
3059 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003061- Issue #1147: Exceptions were directly allowing string exceptions in
3062 their throw() method even though string exceptions no longer
3063 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003064
Georg Brandl3ee81df2008-05-17 18:14:43 +00003065- Issue #1096: Prevent a segfault from getting the repr of a very
3066 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003067
Brett Cannon1e534b52007-09-07 04:18:30 +00003068- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003069 PyObject_Call() never calling back out to Python code to trigger
3070 recursion depth updates/checks. Required the creation of a static
3071 RuntimeError instance in case normalizing an exception put the
3072 recursion check value past its limit. Fixes crashers
3073 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003074

Neal Norwitz0ac60192007-05-27 04:08:54 +00003088- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003089 __*__ attributes. (Some already existed, e.g., __doc__ and
3090 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003091
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003092- Add -3 option to the interpreter to warn about features that are
3093 deprecated and will be changed/removed in Python 3.0.
3094

3096 calls.
3097
Collin Winter62903052007-05-18 23:11:24 +00003098- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003099 "except E as target:". This is to provide forwards compatibility
3100 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003101
Brett Cannon229cee22007-05-05 01:34:02 +00003102- Deprecate BaseException.message as per PEP 352.
3103
Georg Brandl3ee81df2008-05-17 18:14:43 +00003104- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003105 inherited from a builtin base.
3106
Vinay Sajip8549ce32007-05-06 17:53:37 +00003107- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003108 setting a plain string, ie don't expand to single letter identifiers.
3109
Raymond Hettinger13936692007-04-11 18:40:58 +00003110- Request #1191699: Slices can now be pickled.
3111
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003112- Request #1193128: str.translate() now allows a None argument for
3113 translations that only remove characters without re-mapping the
3114 remaining characters.
3115
Georg Brandl5cb76c12007-03-21 09:00:39 +00003116- Patch #1682205: a TypeError while unpacking an iterable is no longer
3117 masked by a generic one with the message "unpack non-sequence".
3118
Neal Norwitzaa754b72007-03-21 06:39:48 +00003119- Remove unused file Python/fmod.c.
3120
Guido van Rossum143b5642007-03-23 04:58:42 +00003121- Bug #1683368: The object.__init__() and object.__new__() methods are
3122 now stricter in rejecting excess arguments. The only time when
3123 either allows excess arguments is when it is not overridden and the
3124 other one is. For backwards compatibility, when both are
3125 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003126 warning later). Also, type.__init__() insists on the same signature
3127 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003128
Georg Brandl3ee81df2008-05-17 18:14:43 +00003129- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3130 object to complex using its __complex__() method before falling back
3131 to the __float__() method. Therefore, the functions in the cmath
3132 module now can operate on objects that define a __complex__()
3133 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003134
Georg Brandl3ee81df2008-05-17 18:14:43 +00003135- Patch #1623563: allow __class__ assignment for classes with
3136 __slots__. The old and the new class are still required to have the
3137 same slot names.

3143 ``object.__reduce_ex__()`` is called with an object that is faking
3144 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003145
Georg Brandl3ee81df2008-05-17 18:14:43 +00003146- Patch #1680015: Don't modify __slots__ tuple if it contains an

3150
Georg Brandl7b9c5552007-03-12 14:30:05 +00003151- Bug #1678647: write a newline after printing an exception in any
3152 case, even when converting the value to a string failed.
3153
Georg Brandl871f1bc2007-03-12 13:17:36 +00003154- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003155 its argument, if it exists. If not, it will work like before. This
3156 allows customizing the output of dir() in the presence of a
3157 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003158
Collin Winter276887b2007-03-12 16:11:39 +00003159- Patch #922167: Python no longer segfaults when faced with infinitely
3160 self-recursive reload() calls (as reported by bug #742342).
3161

3166 parthensized forms. This means complex(repr(x)) now works instead of
3167 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003168
Georg Brandlaa2321b2007-03-07 00:40:28 +00003169- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003170 makes the filenames the warning module prints much more sensible
3171 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003172

3174 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003175 variable is given, but break into the interactive interpreter just
3176 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003184- Patch #1674228: when assigning a slice (old-style), check for the
3185 sq_ass_slice instead of the sq_slice slot.
3186
Georg Brandl3ee81df2008-05-17 18:14:43 +00003187- When printing an unraisable error, don't print exceptions. before
3188 the name. This duplicates the behavior whening normally printing
3189 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003197- Bug #1377858: Fix the segfaulting of the interpreter when an object
3198 created a weakref on itself during a __del__ call for new-style
3199 classes (classic classes still have the bug).

3798 Python would crash instead of raising an error.
3799
Thomas Hellerc2f77252007-03-09 19:21:28 +00003800- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
3801 returned string up to the first NUL character.
3802

3812
Georg Brandl3ee81df2008-05-17 18:14:43 +00003813- unittest now verifies more of its assumptions. In particular,
3814 TestCase and TestSuite subclasses (not instances) are no longer
3815 accepted in TestSuite.addTest(). This should cause no
3816 incompatibility since it never made sense with ordinary subclasses
3817 -- the failure just occurred later, with a more cumbersome
3818 exception.

4101 obtained from the TLS negotiation itself. Patch contributed by Bill
4102 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004103
Georg Brandl3ee81df2008-05-17 18:14:43 +00004104- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004105 that the SMTP.starttls() caller no longer needs to call ehlo()
4106 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004107 does not claim to support starttls. Adds the
4108 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4189 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4190 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004207 time so that opening a database previously created with the DB_DUP
4208 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4209 opens. Specifically: dictionary assignment to a DB object will
4210 replace all values for a given key when the database allows
4211 duplicate values. DB users should use DB.put(k, v) when they want
4212 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004213

4219 characters with ASCII value less than 32. Also, it correctly quotes
4220 dots only if they occur on a single line, as opposed to the previous
4221 behavior of quoting dots if they are the second character of any
4222 line.

4545-----
4546
Georg Brandl3ee81df2008-05-17 18:14:43 +00004547- Unified naming convention for free lists and their limits. All free
4548 lists in Object/ are named ``free_list``, the counter ``numfree``
4549 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4550 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004551
Georg Brandl3ee81df2008-05-17 18:14:43 +00004552- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4553 to ``PyTuple_SetItem``, it can be used to populate a brand new
4554 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004555
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004556- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004558- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4559 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4560 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004561
4562- Patch #1720595: add T_BOOL to the range of structmember types.
4563
4564- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4565 ``PyFloat_GetInfo()`` to the float API.
4566
Georg Brandl3ee81df2008-05-17 18:14:43 +00004567- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4568 of w# format code incorrectly truncated the length to an int, even
4569 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4570 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004571
Georg Brandl3ee81df2008-05-17 18:14:43 +00004572- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4573 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- PEP 3123: Provide forward compatibility with Python 3.0, while
4576 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4577 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004578
Georg Brandl3ee81df2008-05-17 18:14:43 +00004579- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4580 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004581
4582- Patch #1733960: Allow T_LONGLONG to accept ints.

4590- Fix some leftovers from the conversion from int to Py_ssize_t
4591 (relevant to strings and sequences of more than 2**31 items).
4592
4593- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4594 outside of pystate.c and should not be necessary.
4595
Georg Brandl3ee81df2008-05-17 18:14:43 +00004596- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4597 absolute imports. In earlier versions they might have used relative
4598 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004599
Georg Brandl3ee81df2008-05-17 18:14:43 +00004600- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4601 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004602
Georg Brandl3ee81df2008-05-17 18:14:43 +00004603- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004610- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4611 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4612 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4613 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004614
Georg Brandl3ee81df2008-05-17 18:14:43 +00004615- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004628- Removed the macfs module. It had been deprecated since Python 2.5.
4629 This lead to the deprecation of macostools.touched() as it relied
4630 solely on macfs and was a no-op under OS X.
