644 code objects if the original filename is obsolete (which can happen if the
645 file has been renamed, moved, or if it is accessed through different paths).

1055What's New in Python 2.6.1
1056==========================
1057
1058*Release date: 04-Dec-2008*
1059
1060Core and Builtins
1061-----------------
1062
1063- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1064 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1065 instead of throwing a MemoryError.
1066
1067- Issue #4367: Python would segfault during compiling when the unicodedata
1068 module couldn't be imported and \N escapes were present.
1069
1070- Issue #4348: Some bytearray methods returned that didn't cause any change to
1071 the bytearray, returned the same bytearray instead of a copy.
1072
1073- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1074
1075- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1076
1077- Issue #4048: The parser module now correctly validates relative imports.
1078
1079- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1080 exec statement.
1081
1082- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1083 method does not return iterators for the 4th and 5th items.
1084
1085- Issue #4209: Enabling unicode_literals and the print_function in the same
1086 __future__ import didn't work.
1087
1088- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1089 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1090 really executed because I cannot move to such directory on win2k)
1091
1092- Issue #4069: When set.remove(element) is used with a set element, the element
1093 is temporarily replaced with an equivalent frozenset. But the eventual
1094 KeyError would always report the empty frozenset([]) as the missing key. Now
1095 it correctly refers to the initial element.
1096
1097- Fixed C99 style comments in several files. Python is now C89 compatible
1098 again.

1246
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001247- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1248 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1249 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1250 ``printf`` function, whereas PyString_FromFormat has an independent
1251 implementation and uses "%zd" on all platforms for size_t values.
1252 This makes a difference on win64, where ``printf`` needs "%Id" to display
1253 64bit values.

1274 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1276 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1277 type object.

1348 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1349 for catch_warnings() also led to an improvement in the raising of a

1371
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001372- Issue #2975: When compiling several extension modules with Visual Studio 2008
1373 from the same python interpreter, some environment variables would grow

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001413What's New in Python 2.6 beta 3?
1414================================
1415
Barry Warsaw07a4a382008-08-21 01:15:08 +00001416*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001417
1418Core and Builtins
1419-----------------
1420
Guido van Rossumf8402962008-08-20 15:01:50 +00001421- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1422 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1423 extensions do not automatically benefit from the class attribute
1424 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1425 to their tp_flags field if they care. This is a backwards
1426 compatibility feature; in 3.0, all types will use the cache by
1427 default.
1428
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001429- Keyword arguments can now follow starred arguments. (``f(a, *args,
1430 keyword=23)`` is now valid syntax.)
1431
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001432- ctypes function pointers that are COM methods have a boolean True
1433 value again.
1434
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001435- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1436 by denying s# to parse objects that have a releasebuffer procedure,
1437 and introducing s*.
1438
Georg Brandl1e13ea92008-08-11 09:07:59 +00001439- Issue #3537: Fix an assertion failure when an empty but presized dict
1440 object was stored in the freelist.
1441
Mark Dickinsonb6467572008-08-04 21:30:09 +00001442- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1443 ValueError consistently across platforms.
1444
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001445- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1446 (64bit Unix, for example), unichr() would truncate its argument and return
1447 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1448
Neal Norwitze7d8be82008-07-31 17:17:14 +00001449- Apply security patches from Apple.
1450
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001451- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1452 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1453
Antoine Pitrou92f82162008-07-25 22:22:08 +00001454- Issue #1819: function calls with several named parameters are now on
1455 average 35% faster (as measured by pybench).
1456
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001457- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1458 the python debugger steps into a class statement: the free variables (local
1459 variables defined in an outer scope) would be deleted from the outer scope.
1460
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001461- Issue #2620: Overflow checking when allocating or reallocating memory
1462 was not always being done properly in some python types and extension
1463 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1464 all been updated to perform better checks and places in the code that
1465 would previously leak memory on the error path when such an allocation
1466 failed have been fixed.
1467

1469-------
1470
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001471- Issue #3612: Added some missing basic types in ctypes.wintypes.
1472
Benjamin Petersone977ad42008-08-20 01:42:01 +00001473- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1474 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1475
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001476- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1477 version reported by these tools does not necessarily follow the python
1478 version numbering scheme, so the module is less strict when parsing it.
1479
Nick Coghlanf70385a2008-08-18 12:42:46 +00001480- Issue #2235: Added Py3k warnings for types which will become unhashable
1481 under the stricter __hash__ inheritance rules in 3.0. Several types
1482 which did not meet the rules for hash invariants and were already
1483 unhashable in 3.0 have now been explicitly flagged as unhashable in
1484 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1485 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1486
Brett Cannon88f801d2008-08-18 00:46:22 +00001487- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1488 imported into the module but exposed as part of the module's API.
1489
Brett Cannon7b96f072008-08-18 00:41:11 +00001490- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1491
Brett Cannon46225e72008-08-18 00:36:52 +00001492- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001494- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1495
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001496- Issue #3575: Incremental decoder's decode function now takes bytearray
1497 by using 's*' instead of 't#'.
1498
Jesus Cea585ad8a2009-07-02 15:37:21 +00001499- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001500 fails unicode conversion on 2nd parameter. (windows only)
1501
Facundo Batista94f243a2008-08-17 03:38:39 +00001502- Issue 2464. urllib2 now supports a malformation in the URL received
1503 in a redirect.
1504
Brett Cannonabe423e2008-08-16 21:47:07 +00001505- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001506 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001507
Facundo Batistaeb90b782008-08-16 14:44:07 +00001508- Issue #2776: fixed small issue when handling an URL with double slash
1509 after a 302 response in the case of not going through a proxy.
1510
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001511- Issue #2676: in the email package, content-type parsing was hanging on
1512 pathological input because of quadratic or exponential behaviour of a
1513 regular expression.
1514
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001515- Issue #3476: binary buffered reading through the new "io" library is now
1516 thread-safe.
1517
Brett Cannonbf3157b2008-08-14 05:00:03 +00001518- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1519 since mimetools itself is deprecated. Because modules are cached, all
1520 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1521
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001522- Issue #3134: shutil referenced undefined WindowsError symbol.
1523
Robert Schuppenies14646332008-08-10 11:01:53 +00001524- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1525 menu entries were not deleted.
1526
Brett Cannon83e81842008-08-09 23:30:55 +00001527- Copied the implementation of reduce() to _functools.reduce() to have a
1528 version that did not raise a DeprecationWarning under -3.
1529
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001530- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1531 a MemoryError rather than silently stop the iteration.
1532
Guido van Rossum59ce9012008-08-09 14:55:34 +00001533- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1534 to _sre.compile() will now be rejected. This should not affect anybody
1535 since the re.compile() function never generates invalid re-bytecode.
1536
Skip Montanaroa032bf42008-08-08 22:52:51 +00001537- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1538 upon first access it can be automatically initialized from the csv file if
1539 it wasn't initialized during instantiation.
1540
Brett Cannon3aa2a492008-08-06 22:28:09 +00001541- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1542 the reload() built-in has been removed.
1543
Brett Cannon7e30b672008-08-04 21:52:25 +00001544- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001545 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001556 asking for a specific length. This problem only affected files opened
1557 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001558

1583 file name rather than a ZipInfo instance, so files are extracted with
1584 mode 0600 rather than 000 under Unix.
1585
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001586- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1599 interaction with the tp_hash slot (added in 2.6b2) are now documented
1600
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001601- Issue #643841: The language reference now provides more detailed
1602 coverage of the lookup process for special methods. The disclaimers
1603 regarding lack of coverage of new-style classes have also been
1604 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001607What's New in Python 2.6 beta 2?
1608================================
1609
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001610*Release date: 17-Jul-2008*
1611
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001612Core and Builtins
1613-----------------
1614
Georg Brandl3e483f62008-07-16 22:57:41 +00001615- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1616 its methods now allow for items objects that can be converted to
1617 an integer using operator.index().
1618
Mark Dickinson64b7e502008-07-16 09:40:03 +00001619- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1620 produced a ValueError instead of giving the correct float.
1621
Eric Smitha5fa5a22008-07-16 00:11:49 +00001622- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1623 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1624
Mark Dickinson7103aa42008-07-15 19:08:33 +00001625- Issue #3008: the float type has a new instance method 'float.hex'
1626 and a new class method 'float.fromhex' to convert floating-point
1627 numbers to and from hexadecimal strings, respectively.
1628
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001629- Issue #2235: __hash__ is once again inherited by default. To allow
1630 collections.Hashable to remain meaningful in the presence of the
1631 default hash implementation (object.__hash__), it is now possible
1632 to explicit block inheritance of hash by setting __hash__=None at
1633 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1634 level.
1635
Nick Coghlanb028f502008-07-13 14:52:36 +00001636- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1637 the parent module cannot be found while performing an absolute import.
1638 This means that an incorrectly defined __package__ attribute will
1639 now only prevent relative imports in that module rather than causing
1640 all imports from that module to fail.
1641
Nick Coghlan14ff9942008-07-08 14:21:42 +00001642- Issue #2517: Allow unicode messages in Exceptions again by correctly
1643 bypassing the instance dictionary when looking up __unicode__ on
1644 new-style classes.
1645
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001646- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1647 set to a custom object whose write() method happens to install
1648 another file in sys.stdout.
1649
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001650- Issue #3088: Corrected a race condition in classes derived from
1651 threading.local: the first member set by a thread could be saved in
1652 another thread's dictionary.
1653
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001654- Issue #3004: Minor change to slice.indices(): the start and stop
1655 arguments are now treated identically, making the behaviour easier
1656 to describe and understand. For example, slice(None, -10,
1657 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1658 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1659 10, -1).
1660
Georg Brandl278fc502008-07-19 12:46:12 +00001661- Issue #3219: Calling a function with repeated keyword arguments,
1662 f(a=2, a=23), would not cause a syntax error. This was a regression
1663 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001664
Georg Brandl278fc502008-07-19 12:46:12 +00001665- Issue #2862: Make int and float freelist management consistent with
1666 other freelists. Changes their CompactFreeList apis into
1667 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001668

1670-------
1671
Thomas Heller57adf222008-08-14 19:10:48 +00001672- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1673 api functions without holding the GIL, which could lead to a fatal
1674 error when they failed.
1675
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001676- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001684- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1685 ForkingPickler.register() to resolve conflict with ctypes.
1686
Vinay Sajip51e65192008-07-18 09:01:10 +00001687- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001688
Thomas Heller880f5292008-07-15 19:39:38 +00001689- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1690 a valid dlerror() message.
1691
Thomas Heller2bad6572008-07-15 17:19:50 +00001692- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1693 incomplete structure was created.
1694

1698
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001699- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001700
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001701- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1702 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001703 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001704 content-length. The problem had been corrected in the 2.4 branch, but never
1705 merged into trunk.
1706
Georg Brandle78fbcc2008-07-05 10:13:36 +00001707- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00001715 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001716
Vinay Sajip51e65192008-07-18 09:01:10 +00001717- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001718 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001719
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001720- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1721 handling is now the same as that of other special attributes like __name__).
1722
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001723- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1724 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002175- Issue #1631171: Re-implement the 'warnings' module in C (the
2176 original Python code has been kept as backup). This will allow for
2177 using the 'warning's machinery in such places as the parser where
2178 use of pure Python code is not possible. Both the ``showarning()``
2179 and ``formatwarning()`` gain an optional 'line' argument which is
2180 not called by default for backwards-compatibility reasons. Setting
2181 ``warnings.showwarning()`` to an implementation that lacks support
2182 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002245- Issue #2550: The approach used by client/server code for obtaining
2246 ports to listen on in network-oriented tests has been refined in an
2247 effort to facilitate running multiple instances of the entire
2248 regression test suite in parallel without issue.
2249 test_support.bind_port() has been fixed such that it will always
2250 return a unique port -- which wasn't always the case with the
2251 previous implementation, especially if socket options had been set
2252 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2253 new implementation of bind_port() will actually raise an exception
2254 if it is passed an AF_INET/SOCK_STREAM socket with either the
2255 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2256 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2257 the socket it's been passed. This currently only applies to
2258 Windows. This option prevents any other sockets from binding to the
2259 host/port we've bound to, thus removing the possibility of the
2260 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2261 when a second SOCK_STREAM socket binds and accepts to a host/port
2262 that's already been bound by another socket. The optional preferred
2263 port parameter to bind_port() has been removed. Under no
2264 circumstances should tests be hard coding ports!
2265
2266 test_support.find_unused_port() has also been introduced, which will
2267 pass a temporary socket object to bind_port() in order to obtain an
2268 unused port. The temporary socket object is then closed and
2269 deleted, and the port is returned. This method should only be used
2270 for obtaining an unused port in order to pass to an external program
2271 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2272 a parameter to a server-oriented class that doesn't give you direct
2273 access to the underlying socket used.
2274
2275 Finally, test_support.HOST has been introduced, which should be used
2276 for the host argument of any relevant socket calls (i.e. bind and
2277 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002278
2279 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002280 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002281 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2282 test_asynchat and test_socket_ssl.
2283
Georg Brandl3ee81df2008-05-17 18:14:43 +00002284 It is now possible for multiple instances of the regression test
2285 suite to run in parallel without issue.

2552-----------------
2553
Fred Drakea8ee94b2008-03-01 02:45:07 +00002554- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002555 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002560
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002561- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002562 issue 215555 for a discussion.
2563
Eric Smitha73fbe72008-02-23 03:09:44 +00002564- Added the future_builtins module, which contains hex() and oct().
2565 These are the PEP 3127 version of these functions, designed to be
2566 compatible with the hex() and oct() builtins from Python 3.0. They
2567 differ slightly in their output formats from the existing, unchanged
2568 Python 2.6 builtins. The expected usage of the future_builtins
2569 module is:
2570 from future_builtins import hex, oct
2571
Eric Smith7ef40bf2008-02-20 23:34:22 +00002572- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2573 exponents for exponents with absolute value < 100. Follows C99
2574 standard. This is a change on Windows, which would use 3 digits.
2575 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2576 so that any alterations it does to the resulting string will be
2577 available in stringlib/formatter.h (for float.__format__).
2578
Eric Smith5a3c1352008-02-19 13:21:56 +00002579- Implemented PEP 3101, Advanced String Formatting. This adds a new
2580 builtin format(); a format() method for str and unicode; a
2581 __format__() method to object, str, unicode, int, long, float, and
2582 datetime; the class string.Formatter; and the C API
2583 PyObject_Format().
2584
Georg Brandl3ee81df2008-05-17 18:14:43 +00002585- Fixed several potential crashes, all caused by specially crafted
2586 __del__ methods exploiting objects in temporarily inconsistent
2587 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002588
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002589- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002590 prevent a possible crash: an Abstract Base Class would try to access
2591 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002596- Clear all free lists during a gc.collect() of the highest generation
2597 in order to allow pymalloc to free more arenas. Python may give back
2598 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002599
Georg Brandl3ee81df2008-05-17 18:14:43 +00002600- Issue #2045: Fix an infinite recursion triggered when printing a
2601 subclass of collections.defaultdict, if its default_factory is set
2602 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002603
Christian Heimesf75dbef2008-02-08 00:11:31 +00002604- Fixed a minor memory leak in dictobject.c. The content of the free
2605 list was not freed on interpreter shutdown.
2606
Georg Brandl3ee81df2008-05-17 18:14:43 +00002607- Limit free list of method and builtin function objects to 256
2608 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002610- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2611 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002612 to compact the internal free lists of pre-allocted ints and floats.
2613
Georg Brandl3ee81df2008-05-17 18:14:43 +00002614- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2615 calls. Python expected the return type int but the fork familie
2616 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002617

2628 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002629
Georg Brandl3ee81df2008-05-17 18:14:43 +00002630- Patch #1473257: generator objects gain a gi_code attribute. This is
2631 the same object as the func_code attribute of the function that
2632 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002633
Georg Brandl3ee81df2008-05-17 18:14:43 +00002634- Issue #1920: "while 0" statements were completely removed by the
2635 compiler, even in the presence of an "else" clause, which is
2636 supposed to be run when the condition is false. Now the compiler
2637 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002638
Guido van Rossumeead05f2008-01-24 18:21:02 +00002639- A few crashers fixed: weakref_in_del.py (issue #1377858);

2641 borrowed_ref_[34].py (not in tracker).
2642
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002643- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002644 suppressed while an extension is loaded by calling SetErrorMode in

2646
Georg Brandl3ee81df2008-05-17 18:14:43 +00002647- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002648 several extension methods and modules do not work without unicode
2649 support.
2650
Georg Brandl26543b12008-01-21 18:36:51 +00002651- Issue #1882: when compiling code from a string, encoding cookies in the
2652 second line of code were not always recognized correctly.
2653
Georg Brandl14404b62008-01-19 19:27:05 +00002654- Issue #1679: "0x" was taken as a valid integer literal.
2655
Georg Brandl6caad7d2008-01-26 14:19:22 +00002656- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002657 added.
2658
Christian Heimesc94e2b52008-01-14 04:13:37 +00002659- sys.float_info / PyFloat_GetInfo: The floating point information
2660 object was converted from a dict to a specialized structseq object.
2661
Georg Brandl3ee81df2008-05-17 18:14:43 +00002662- Patch #1816: Added sys.flags structseq. It exposes the status of
2663 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002664
Georg Brandl3ee81df2008-05-17 18:14:43 +00002665- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00002681- Improve some exception messages when Windows fails to load an
2682 extension module. Now we get for example '%1 is not a valid Win32
2683 application' instead of 'error code 193'.

2696 dictionary size. There is a new opcode, STORE_MAP, for adding
2697 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002726- Patch #1739468: Directories and zipfiles containing a __main__.py
2727 file can now be directly executed by passing their name to the
2728 interpreter. The directory/zipfile is automatically inserted as the
2729 first entry in sys.path.

2740
Georg Brandl3ee81df2008-05-17 18:14:43 +00002741- The enumerate() builtin function is no longer bounded to sequences
2742 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2743 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002744
Georg Brandl3ee81df2008-05-17 18:14:43 +00002745- Issue #1686386: Tuple's tp_repr did not take into account the
2746 possibility of having a self-referential tuple, which is possible
2747 from C code. Nor did object's tp_str consider that a type's tp_str
2748 could do something that could lead to an inifinite recursion.
2749 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2750 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002751
Georg Brandl3ee81df2008-05-17 18:14:43 +00002752- Issue #1164: It was possible to trigger deadlock when using the
2753 'print' statement to write to a file since the GIL was not released
2754 as needed. Now PyObject_Print() does the right thing along with
2755 various tp_print implementations of the built-in types and those in
2756 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00002765- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002766 PyObject_Call() never calling back out to Python code to trigger
2767 recursion depth updates/checks. Required the creation of a static
2768 RuntimeError instance in case normalizing an exception put the
2769 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00002785- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002786 __*__ attributes. (Some already existed, e.g., __doc__ and
2787 __name__.)

Georg Brandl2134e752007-05-21 20:34:16 +00002792- Patch #1686487: you can now pass any mapping after '**' in function
2793 calls.
2794
Collin Winter62903052007-05-18 23:11:24 +00002795- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002796 "except E as target:". This is to provide forwards compatibility
2797 with Python 3.0.

2803
Vinay Sajip8549ce32007-05-06 17:53:37 +00002804- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002805 setting a plain string, ie don't expand to single letter identifiers.
2806
Raymond Hettinger13936692007-04-11 18:40:58 +00002807- Request #1191699: Slices can now be pickled.
2808
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002809- Request #1193128: str.translate() now allows a None argument for

2811 remaining characters.
2812
Georg Brandl5cb76c12007-03-21 09:00:39 +00002813- Patch #1682205: a TypeError while unpacking an iterable is no longer

2817
Guido van Rossum143b5642007-03-23 04:58:42 +00002818- Bug #1683368: The object.__init__() and object.__new__() methods are
2819 now stricter in rejecting excess arguments. The only time when
2820 either allows excess arguments is when it is not overridden and the
2821 other one is. For backwards compatibility, when both are
2822 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002823 warning later). Also, type.__init__() insists on the same signature
2824 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002825
Georg Brandl3ee81df2008-05-17 18:14:43 +00002826- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2827 object to complex using its __complex__() method before falling back
2828 to the __float__() method. Therefore, the functions in the cmath
2829 module now can operate on objects that define a __complex__()
2830 method.

2847
Georg Brandl7b9c5552007-03-12 14:30:05 +00002848- Bug #1678647: write a newline after printing an exception in any
2849 case, even when converting the value to a string failed.
2850
Georg Brandl871f1bc2007-03-12 13:17:36 +00002851- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002852 its argument, if it exists. If not, it will work like before. This
2853 allows customizing the output of dir() in the presence of a
2854 __getattr__().

2863 parthensized forms. This means complex(repr(x)) now works instead of
2864 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002865
Georg Brandlaa2321b2007-03-07 00:40:28 +00002866- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867 makes the filenames the warning module prints much more sensible
2868 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002869

Georg Brandl0fca97a2007-03-05 22:28:08 +00002881- Patch #1674228: when assigning a slice (old-style), check for the
2882 sq_ass_slice instead of the sq_slice slot.
2883
Georg Brandl3ee81df2008-05-17 18:14:43 +00002884- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003419 AttributeError instead of an IOError when the server's response
3420 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003421

Georg Brandl3ee81df2008-05-17 18:14:43 +00003437- Patch #1530482: add pydoc.render_doc() which returns the

3452
Georg Brandl92a6bae2007-03-13 17:43:32 +00003453- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003454 are set for invalid interpolation sequences that would lead to
3455 errors on reading back those values.

3498 returned string up to the first NUL character.

3509
Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- unittest now verifies more of its assumptions. In particular,
3511 TestCase and TestSuite subclasses (not instances) are no longer
3512 accepted in TestSuite.addTest(). This should cause no
3513 incompatibility since it never made sense with ordinary subclasses
3514 -- the failure just occurred later, with a more cumbersome
3515 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003904 time so that opening a database previously created with the DB_DUP
3905 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3906 opens. Specifically: dictionary assignment to a DB object will
3907 replace all values for a given key when the database allows
3908 duplicate values. DB users should use DB.put(k, v) when they want
3909 to store duplicates; not DB[k] = v.

3918 behavior of quoting dots if they are the second character of any
3919 line.

4265 of w# format code incorrectly truncated the length to an int, even
4266 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4267 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004297- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4298 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
