1058What's New in Python 2.6.1
1059==========================
1060
1061*Release date: 04-Dec-2008*
1062
1063Core and Builtins
1064-----------------
1065
1066- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1067 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1068 instead of throwing a MemoryError.
1069
1070- Issue #4367: Python would segfault during compiling when the unicodedata
1071 module couldn't be imported and \N escapes were present.
1072
1073- Issue #4348: Some bytearray methods returned that didn't cause any change to
1074 the bytearray, returned the same bytearray instead of a copy.
1075
1076- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1077
1078- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1079
1080- Issue #4048: The parser module now correctly validates relative imports.
1081
1082- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1086 method does not return iterators for the 4th and 5th items.
1087
1088- Issue #4209: Enabling unicode_literals and the print_function in the same
1089 __future__ import didn't work.
1090
1091- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1092 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1093 really executed because I cannot move to such directory on win2k)
1094
1095- Issue #4069: When set.remove(element) is used with a set element, the element
1096 is temporarily replaced with an equivalent frozenset. But the eventual
1097 KeyError would always report the empty frozenset([]) as the missing key. Now
1098 it correctly refers to the initial element.
1099
1100- Fixed C99 style comments in several files. Python is now C89 compatible
1101 again.

1249
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001250- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1251 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1252 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1253 ``printf`` function, whereas PyString_FromFormat has an independent
1254 implementation and uses "%zd" on all platforms for size_t values.
1255 This makes a difference on win64, where ``printf`` needs "%Id" to display
1256 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001258- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Vinay Sajip35e3b032008-09-01 14:33:59 +00001275- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001276 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1277 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1278 when given a tuple of classes as second argument, were looking up
1279 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1280 type object.

1351 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1352 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001375- Issue #2975: When compiling several extension modules with Visual Studio 2008
1376 from the same python interpreter, some environment variables would grow
1377 without limit.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001416What's New in Python 2.6 beta 3?
1417================================
1418
Barry Warsaw07a4a382008-08-21 01:15:08 +00001419*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001420
1421Core and Builtins
1422-----------------
1423
Guido van Rossumf8402962008-08-20 15:01:50 +00001424- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1425 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1426 extensions do not automatically benefit from the class attribute
1427 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1428 to their tp_flags field if they care. This is a backwards
1429 compatibility feature; in 3.0, all types will use the cache by
1430 default.
1431
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001432- Keyword arguments can now follow starred arguments. (``f(a, *args,
1433 keyword=23)`` is now valid syntax.)
1434
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001435- ctypes function pointers that are COM methods have a boolean True
1436 value again.
1437
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001438- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1439 by denying s# to parse objects that have a releasebuffer procedure,
1440 and introducing s*.
1441
Georg Brandl1e13ea92008-08-11 09:07:59 +00001442- Issue #3537: Fix an assertion failure when an empty but presized dict
1443 object was stored in the freelist.
1444
Mark Dickinsonb6467572008-08-04 21:30:09 +00001445- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1446 ValueError consistently across platforms.
1447
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001448- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1449 (64bit Unix, for example), unichr() would truncate its argument and return
1450 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1451
Neal Norwitze7d8be82008-07-31 17:17:14 +00001452- Apply security patches from Apple.
1453
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001454- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1455 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1456
Antoine Pitrou92f82162008-07-25 22:22:08 +00001457- Issue #1819: function calls with several named parameters are now on
1458 average 35% faster (as measured by pybench).
1459
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001460- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1461 the python debugger steps into a class statement: the free variables (local
1462 variables defined in an outer scope) would be deleted from the outer scope.
1463
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001464- Issue #2620: Overflow checking when allocating or reallocating memory
1465 was not always being done properly in some python types and extension
1466 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1467 all been updated to perform better checks and places in the code that
1468 would previously leak memory on the error path when such an allocation
1469 failed have been fixed.

1473
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001474- Issue #3612: Added some missing basic types in ctypes.wintypes.
1475
Benjamin Petersone977ad42008-08-20 01:42:01 +00001476- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1477 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1478
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001479- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1480 version reported by these tools does not necessarily follow the python
1481 version numbering scheme, so the module is less strict when parsing it.
1482
Nick Coghlanf70385a2008-08-18 12:42:46 +00001483- Issue #2235: Added Py3k warnings for types which will become unhashable
1484 under the stricter __hash__ inheritance rules in 3.0. Several types
1485 which did not meet the rules for hash invariants and were already
1486 unhashable in 3.0 have now been explicitly flagged as unhashable in
1487 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1488 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1489
Brett Cannon88f801d2008-08-18 00:46:22 +00001490- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1491 imported into the module but exposed as part of the module's API.
1492
Brett Cannon7b96f072008-08-18 00:41:11 +00001493- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1494
Brett Cannon46225e72008-08-18 00:36:52 +00001495- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001497- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1498
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001499- Issue #3575: Incremental decoder's decode function now takes bytearray
1500 by using 's*' instead of 't#'.
1501
Jesus Cea585ad8a2009-07-02 15:37:21 +00001502- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001503 fails unicode conversion on 2nd parameter. (windows only)
1504
Facundo Batista94f243a2008-08-17 03:38:39 +00001505- Issue 2464. urllib2 now supports a malformation in the URL received
1506 in a redirect.
1507
Brett Cannonabe423e2008-08-16 21:47:07 +00001508- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001509 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001510
Facundo Batistaeb90b782008-08-16 14:44:07 +00001511- Issue #2776: fixed small issue when handling an URL with double slash
1512 after a 302 response in the case of not going through a proxy.
1513
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001514- Issue #2676: in the email package, content-type parsing was hanging on
1515 pathological input because of quadratic or exponential behaviour of a
1516 regular expression.
1517
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001518- Issue #3476: binary buffered reading through the new "io" library is now
1519 thread-safe.
1520
Brett Cannonbf3157b2008-08-14 05:00:03 +00001521- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1522 since mimetools itself is deprecated. Because modules are cached, all
1523 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1524
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001525- Issue #3134: shutil referenced undefined WindowsError symbol.
1526
Robert Schuppenies14646332008-08-10 11:01:53 +00001527- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1528 menu entries were not deleted.
1529
Brett Cannon83e81842008-08-09 23:30:55 +00001530- Copied the implementation of reduce() to _functools.reduce() to have a
1531 version that did not raise a DeprecationWarning under -3.
1532
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001533- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1534 a MemoryError rather than silently stop the iteration.
1535
Guido van Rossum59ce9012008-08-09 14:55:34 +00001536- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1537 to _sre.compile() will now be rejected. This should not affect anybody
1538 since the re.compile() function never generates invalid re-bytecode.
1539
Skip Montanaroa032bf42008-08-08 22:52:51 +00001540- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1541 upon first access it can be automatically initialized from the csv file if
1542 it wasn't initialized during instantiation.
1543
Brett Cannon3aa2a492008-08-06 22:28:09 +00001544- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1545 the reload() built-in has been removed.
1546
Brett Cannon7e30b672008-08-04 21:52:25 +00001547- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001548 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001559 asking for a specific length. This problem only affected files opened
1560 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001561

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001585- Issue #3394: zipfile.writestr sets external attributes when passed a
1586 file name rather than a ZipInfo instance, so files are extracted with
1587 mode 0600 rather than 000 under Unix.

Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001589- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1590 argument in python 2.5, this broke code that subclassed Popen to include its
1591 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1603
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001604- Issue #643841: The language reference now provides more detailed
1605 coverage of the lookup process for special methods. The disclaimers
1606 regarding lack of coverage of new-style classes have also been
1607 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001610What's New in Python 2.6 beta 2?
1611================================
1612
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001613*Release date: 17-Jul-2008*
1614
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001615Core and Builtins
1616-----------------
1617
Georg Brandl3e483f62008-07-16 22:57:41 +00001618- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1619 its methods now allow for items objects that can be converted to
1620 an integer using operator.index().
1621
Mark Dickinson64b7e502008-07-16 09:40:03 +00001622- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1623 produced a ValueError instead of giving the correct float.
1624
Eric Smitha5fa5a22008-07-16 00:11:49 +00001625- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1626 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1627
Mark Dickinson7103aa42008-07-15 19:08:33 +00001628- Issue #3008: the float type has a new instance method 'float.hex'
1629 and a new class method 'float.fromhex' to convert floating-point
1630 numbers to and from hexadecimal strings, respectively.
1631
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001632- Issue #2235: __hash__ is once again inherited by default. To allow
1633 collections.Hashable to remain meaningful in the presence of the
1634 default hash implementation (object.__hash__), it is now possible
1635 to explicit block inheritance of hash by setting __hash__=None at
1636 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1637 level.
1638
Nick Coghlanb028f502008-07-13 14:52:36 +00001639- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1640 the parent module cannot be found while performing an absolute import.
1641 This means that an incorrectly defined __package__ attribute will
1642 now only prevent relative imports in that module rather than causing
1643 all imports from that module to fail.
1644
Nick Coghlan14ff9942008-07-08 14:21:42 +00001645- Issue #2517: Allow unicode messages in Exceptions again by correctly
1646 bypassing the instance dictionary when looking up __unicode__ on
1647 new-style classes.
1648
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001649- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1650 set to a custom object whose write() method happens to install
1651 another file in sys.stdout.
1652
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001653- Issue #3088: Corrected a race condition in classes derived from
1654 threading.local: the first member set by a thread could be saved in
1655 another thread's dictionary.
1656
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001657- Issue #3004: Minor change to slice.indices(): the start and stop
1658 arguments are now treated identically, making the behaviour easier
1659 to describe and understand. For example, slice(None, -10,
1660 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1661 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1662 10, -1).
1663
Georg Brandl278fc502008-07-19 12:46:12 +00001664- Issue #3219: Calling a function with repeated keyword arguments,
1665 f(a=2, a=23), would not cause a syntax error. This was a regression
1666 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001667
Georg Brandl278fc502008-07-19 12:46:12 +00001668- Issue #2862: Make int and float freelist management consistent with
1669 other freelists. Changes their CompactFreeList apis into
1670 ClearFreeList apis and calls them via gc.collect().

1676 api functions without holding the GIL, which could lead to a fatal
1677 error when they failed.
1678
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001679- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1688 ForkingPickler.register() to resolve conflict with ctypes.
1689
Vinay Sajip51e65192008-07-18 09:01:10 +00001690- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001691
Thomas Heller880f5292008-07-15 19:39:38 +00001692- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1693 a valid dlerror() message.

1701
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001702- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001703
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001704- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1705 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001706 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001707 content-length. The problem had been corrected in the 2.4 branch, but never
1708 merged into trunk.
1709
Georg Brandle78fbcc2008-07-05 10:13:36 +00001710- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001723- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1724 handling is now the same as that of other special attributes like __name__).
1725
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001726- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1727 removal in Python 3.0 in favor of urllib2.urlopen().

2180 using the 'warning's machinery in such places as the parser where
2181 use of pure Python code is not possible. Both the ``showarning()``
2182 and ``formatwarning()`` gain an optional 'line' argument which is
2183 not called by default for backwards-compatibility reasons. Setting
2184 ``warnings.showwarning()`` to an implementation that lacks support
2185 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002248- Issue #2550: The approach used by client/server code for obtaining
2249 ports to listen on in network-oriented tests has been refined in an
2250 effort to facilitate running multiple instances of the entire
2251 regression test suite in parallel without issue.
2252 test_support.bind_port() has been fixed such that it will always
2253 return a unique port -- which wasn't always the case with the
2254 previous implementation, especially if socket options had been set
2255 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2256 new implementation of bind_port() will actually raise an exception
2257 if it is passed an AF_INET/SOCK_STREAM socket with either the
2258 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2259 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2260 the socket it's been passed. This currently only applies to
2261 Windows. This option prevents any other sockets from binding to the
2262 host/port we've bound to, thus removing the possibility of the
2263 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2264 when a second SOCK_STREAM socket binds and accepts to a host/port
2265 that's already been bound by another socket. The optional preferred
2266 port parameter to bind_port() has been removed. Under no
2267 circumstances should tests be hard coding ports!
2268
2269 test_support.find_unused_port() has also been introduced, which will
2270 pass a temporary socket object to bind_port() in order to obtain an
2271 unused port. The temporary socket object is then closed and
2272 deleted, and the port is returned. This method should only be used
2273 for obtaining an unused port in order to pass to an external program
2274 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2275 a parameter to a server-oriented class that doesn't give you direct
2276 access to the underlying socket used.
2277
2278 Finally, test_support.HOST has been introduced, which should be used
2279 for the host argument of any relevant socket calls (i.e. bind and
2280 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002281
2282 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002283 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002284 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2285 test_asynchat and test_socket_ssl.
2286
Georg Brandl3ee81df2008-05-17 18:14:43 +00002287 It is now possible for multiple instances of the regression test
2288 suite to run in parallel without issue.

2554Core and builtins
2555-----------------
2556
Fred Drakea8ee94b2008-03-01 02:45:07 +00002557- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002558 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002559
Georg Brandlad61bc82008-02-23 15:11:18 +00002560- Issue #2067: file.__exit__() now calls subclasses' close() method.
2561
2562- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002563
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002564- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002565 issue 215555 for a discussion.
2566
Eric Smitha73fbe72008-02-23 03:09:44 +00002567- Added the future_builtins module, which contains hex() and oct().
2568 These are the PEP 3127 version of these functions, designed to be
2569 compatible with the hex() and oct() builtins from Python 3.0. They
2570 differ slightly in their output formats from the existing, unchanged
2571 Python 2.6 builtins. The expected usage of the future_builtins
2572 module is:
2573 from future_builtins import hex, oct
2574
Eric Smith7ef40bf2008-02-20 23:34:22 +00002575- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2576 exponents for exponents with absolute value < 100. Follows C99
2577 standard. This is a change on Windows, which would use 3 digits.
2578 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2579 so that any alterations it does to the resulting string will be
2580 available in stringlib/formatter.h (for float.__format__).
2581
Eric Smith5a3c1352008-02-19 13:21:56 +00002582- Implemented PEP 3101, Advanced String Formatting. This adds a new
2583 builtin format(); a format() method for str and unicode; a
2584 __format__() method to object, str, unicode, int, long, float, and
2585 datetime; the class string.Formatter; and the C API
2586 PyObject_Format().
2587
Georg Brandl3ee81df2008-05-17 18:14:43 +00002588- Fixed several potential crashes, all caused by specially crafted
2589 __del__ methods exploiting objects in temporarily inconsistent
2590 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002591
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002592- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002593 prevent a possible crash: an Abstract Base Class would try to access
2594 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002595

Georg Brandl3ee81df2008-05-17 18:14:43 +00002599- Clear all free lists during a gc.collect() of the highest generation
2600 in order to allow pymalloc to free more arenas. Python may give back
2601 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002602
Georg Brandl3ee81df2008-05-17 18:14:43 +00002603- Issue #2045: Fix an infinite recursion triggered when printing a
2604 subclass of collections.defaultdict, if its default_factory is set
2605 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002606
Christian Heimesf75dbef2008-02-08 00:11:31 +00002607- Fixed a minor memory leak in dictobject.c. The content of the free
2608 list was not freed on interpreter shutdown.
2609
Georg Brandl3ee81df2008-05-17 18:14:43 +00002610- Limit free list of method and builtin function objects to 256
2611 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002612
Georg Brandl3ee81df2008-05-17 18:14:43 +00002613- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2614 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002615 to compact the internal free lists of pre-allocted ints and floats.
2616
Georg Brandl3ee81df2008-05-17 18:14:43 +00002617- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2618 calls. Python expected the return type int but the fork familie
2619 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002620
Georg Brandl3ee81df2008-05-17 18:14:43 +00002621- Issue #1678380: Fix a bug that identifies 0j and -0j when they

2631 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002632
Georg Brandl3ee81df2008-05-17 18:14:43 +00002633- Patch #1473257: generator objects gain a gi_code attribute. This is
2634 the same object as the func_code attribute of the function that
2635 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002636
Georg Brandl3ee81df2008-05-17 18:14:43 +00002637- Issue #1920: "while 0" statements were completely removed by the
2638 compiler, even in the presence of an "else" clause, which is
2639 supposed to be run when the condition is false. Now the compiler
2640 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002641
Guido van Rossumeead05f2008-01-24 18:21:02 +00002642- A few crashers fixed: weakref_in_del.py (issue #1377858);
2643 loosing_dict_ref.py (issue #1303614, test67.py);
2644 borrowed_ref_[34].py (not in tracker).
2645
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002646- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002647 suppressed while an extension is loaded by calling SetErrorMode in

2649
Georg Brandl3ee81df2008-05-17 18:14:43 +00002650- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002651 several extension methods and modules do not work without unicode
2652 support.
2653
Georg Brandl26543b12008-01-21 18:36:51 +00002654- Issue #1882: when compiling code from a string, encoding cookies in the
2655 second line of code were not always recognized correctly.
2656
Georg Brandl14404b62008-01-19 19:27:05 +00002657- Issue #1679: "0x" was taken as a valid integer literal.
2658
Georg Brandl6caad7d2008-01-26 14:19:22 +00002659- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002660 added.
2661
Christian Heimesc94e2b52008-01-14 04:13:37 +00002662- sys.float_info / PyFloat_GetInfo: The floating point information
2663 object was converted from a dict to a specialized structseq object.
2664
Georg Brandl3ee81df2008-05-17 18:14:43 +00002665- Patch #1816: Added sys.flags structseq. It exposes the status of
2666 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002667
Georg Brandl3ee81df2008-05-17 18:14:43 +00002668- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00002672- Patch #1700288: added a type attribute cache that caches method
2673 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002674
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002675- Bug #1776: __import__() no longer accepts filenames on any platform.
2676 The first parameter to __import__() must be a valid module name.

2681 envvar and sys.dont_write_bytecode attribute. All these can be set
2682 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002684- Improve some exception messages when Windows fails to load an
2685 extension module. Now we get for example '%1 is not a valid Win32
2686 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00002693- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002694 and INF. float("nan"), float("inf") and float("-inf") now work on
2695 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002697- Compiler now generates simpler and faster code for dictionary
2698 literals. The oparg for BUILD_MAP now indicates an estimated
2699 dictionary size. There is a new opcode, STORE_MAP, for adding
2700 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002729- Patch #1739468: Directories and zipfiles containing a __main__.py
2730 file can now be directly executed by passing their name to the
2731 interpreter. The directory/zipfile is automatically inserted as the
2732 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002734- Issue #1265: Fix a problem with sys.settrace, if the tracing
2735 function uses a generator expression when at the same time the
2736 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002737
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002738- sets and frozensets now have an isdisjoint() method.

2741
Neal Norwitz44f326e2007-10-05 05:29:17 +00002742- Fix warnings found by the new version of the Coverity checker.
2743
Georg Brandl3ee81df2008-05-17 18:14:43 +00002744- The enumerate() builtin function is no longer bounded to sequences
2745 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2746 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002747
Georg Brandl3ee81df2008-05-17 18:14:43 +00002748- Issue #1686386: Tuple's tp_repr did not take into account the
2749 possibility of having a self-referential tuple, which is possible
2750 from C code. Nor did object's tp_str consider that a type's tp_str
2751 could do something that could lead to an inifinite recursion.
2752 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2753 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002754
Georg Brandl3ee81df2008-05-17 18:14:43 +00002755- Issue #1164: It was possible to trigger deadlock when using the
2756 'print' statement to write to a file since the GIL was not released
2757 as needed. Now PyObject_Print() does the right thing along with
2758 various tp_print implementations of the built-in types and those in
2759 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002760
Georg Brandl3ee81df2008-05-17 18:14:43 +00002761- Issue #1147: Exceptions were directly allowing string exceptions in
2762 their throw() method even though string exceptions no longer
2763 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002764
Georg Brandl3ee81df2008-05-17 18:14:43 +00002765- Issue #1096: Prevent a segfault from getting the repr of a very
2766 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002767
Brett Cannon1e534b52007-09-07 04:18:30 +00002768- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002769 PyObject_Call() never calling back out to Python code to trigger
2770 recursion depth updates/checks. Required the creation of a static
2771 RuntimeError instance in case normalizing an exception put the
2772 recursion check value past its limit. Fixes crashers
2773 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002774

Neal Norwitz0ac60192007-05-27 04:08:54 +00002788- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002789 __*__ attributes. (Some already existed, e.g., __doc__ and
2790 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002791
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002792- Add -3 option to the interpreter to warn about features that are
2793 deprecated and will be changed/removed in Python 3.0.
2794
Georg Brandl2134e752007-05-21 20:34:16 +00002795- Patch #1686487: you can now pass any mapping after '**' in function
2796 calls.
2797
Collin Winter62903052007-05-18 23:11:24 +00002798- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002799 "except E as target:". This is to provide forwards compatibility
2800 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002801
Brett Cannon229cee22007-05-05 01:34:02 +00002802- Deprecate BaseException.message as per PEP 352.
2803
Georg Brandl3ee81df2008-05-17 18:14:43 +00002804- Issue #1303614: don't expose object's __dict__ when the dict is

2806
Vinay Sajip8549ce32007-05-06 17:53:37 +00002807- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002808 setting a plain string, ie don't expand to single letter identifiers.
2809
Raymond Hettinger13936692007-04-11 18:40:58 +00002810- Request #1191699: Slices can now be pickled.
2811
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002812- Request #1193128: str.translate() now allows a None argument for
2813 translations that only remove characters without re-mapping the
2814 remaining characters.
2815
Georg Brandl5cb76c12007-03-21 09:00:39 +00002816- Patch #1682205: a TypeError while unpacking an iterable is no longer
2817 masked by a generic one with the message "unpack non-sequence".
2818
Neal Norwitzaa754b72007-03-21 06:39:48 +00002819- Remove unused file Python/fmod.c.
2820
Guido van Rossum143b5642007-03-23 04:58:42 +00002821- Bug #1683368: The object.__init__() and object.__new__() methods are
2822 now stricter in rejecting excess arguments. The only time when
2823 either allows excess arguments is when it is not overridden and the
2824 other one is. For backwards compatibility, when both are
2825 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002826 warning later). Also, type.__init__() insists on the same signature
2827 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002828
Georg Brandl3ee81df2008-05-17 18:14:43 +00002829- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2830 object to complex using its __complex__() method before falling back
2831 to the __float__() method. Therefore, the functions in the cmath
2832 module now can operate on objects that define a __complex__()
2833 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002834
Georg Brandl3ee81df2008-05-17 18:14:43 +00002835- Patch #1623563: allow __class__ assignment for classes with
2836 __slots__. The old and the new class are still required to have the
2837 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002838
Georg Brandl3ee81df2008-05-17 18:14:43 +00002839- Patch #1642547: Fix an error/crash when encountering syntax errors

2843 ``object.__reduce_ex__()`` is called with an object that is faking
2844 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002845
Georg Brandl3ee81df2008-05-17 18:14:43 +00002846- Patch #1680015: Don't modify __slots__ tuple if it contains an

2850
Georg Brandl7b9c5552007-03-12 14:30:05 +00002851- Bug #1678647: write a newline after printing an exception in any
2852 case, even when converting the value to a string failed.
2853
Georg Brandl871f1bc2007-03-12 13:17:36 +00002854- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002855 its argument, if it exists. If not, it will work like before. This
2856 allows customizing the output of dir() in the presence of a
2857 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002858
Collin Winter276887b2007-03-12 16:11:39 +00002859- Patch #922167: Python no longer segfaults when faced with infinitely
2860 self-recursive reload() calls (as reported by bug #742342).
2861
Georg Brandl3ee81df2008-05-17 18:14:43 +00002862- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002865- Patch #1491866: change the complex() constructor to allow
2866 parthensized forms. This means complex(repr(x)) now works instead of
2867 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002868
Georg Brandlaa2321b2007-03-07 00:40:28 +00002869- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002870 makes the filenames the warning module prints much more sensible
2871 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002872
Georg Brandl49aafc92007-03-07 00:34:46 +00002873- Variant of patch #697613: don't exit the interpreter on a SystemExit
2874 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002875 variable is given, but break into the interactive interpreter just
2876 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002884- Patch #1674228: when assigning a slice (old-style), check for the
2885 sq_ass_slice instead of the sq_slice slot.
2886
Georg Brandl3ee81df2008-05-17 18:14:43 +00002887- When printing an unraisable error, don't print exceptions. before
2888 the name. This duplicates the behavior whening normally printing
2889 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003422 AttributeError instead of an IOError when the server's response
3423 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003424

Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Patch #1429539: pdb now correctly initializes the __main__ module
3430 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003431 correctly now.
3432

3439
Georg Brandl3ee81df2008-05-17 18:14:43 +00003440- Patch #1530482: add pydoc.render_doc() which returns the

3455
Georg Brandl92a6bae2007-03-13 17:43:32 +00003456- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003457 are set for invalid interpolation sequences that would lead to
3458 errors on reading back those values.

3501 returned string up to the first NUL character.
3502

3512
Georg Brandl3ee81df2008-05-17 18:14:43 +00003513- unittest now verifies more of its assumptions. In particular,
3514 TestCase and TestSuite subclasses (not instances) are no longer
3515 accepted in TestSuite.addTest(). This should cause no
3516 incompatibility since it never made sense with ordinary subclasses
3517 -- the failure just occurred later, with a more cumbersome
3518 exception.

3528
Georg Brandl3ee81df2008-05-17 18:14:43 +00003529- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003907 time so that opening a database previously created with the DB_DUP
3908 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3909 opens. Specifically: dictionary assignment to a DB object will
3910 replace all values for a given key when the database allows
3911 duplicate values. DB users should use DB.put(k, v) when they want
3912 to store duplicates; not DB[k] = v.

3919 characters with ASCII value less than 32. Also, it correctly quotes
3920 dots only if they occur on a single line, as opposed to the previous
3921 behavior of quoting dots if they are the second character of any
3922 line.

4268 of w# format code incorrectly truncated the length to an int, even
4269 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4270 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004300- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4301 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
