28
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +000029- Issue #3720: Fix a crash when an iterator modifies its class and removes its

45 an existing .py counterpart, override the co_filename attributes of all
46 code objects if the original filename is obsolete (which can happen if the
47 file has been renamed, moved, or if it is accessed through different paths).
48 Patch by Ziga Seilnacht and Jean-Paul Calderone.
49
Martin v. Löwis5344c992009-01-02 20:32:55 +000050- Issue #4075: Use OutputDebugStringW in Py_FatalError.
51
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +000052- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
53 file with `str' filename on Windows.
54
Antoine Pitrouaa687902009-01-01 14:11:22 +000055- Issue #3680: Reference cycles created through a dict, set or deque iterator

59 where the tp_hash and tp_dict slots are both NULL.
60
Benjamin Peterson7af65562008-12-29 17:56:58 +000061- Issue #4764: With io.open, IOError.filename is set when trying to open a
62 directory on POSIX systems.
63
Benjamin Petersonfe231b02008-12-29 17:47:42 +000064- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

83 context manager returns a value that cannot be converted to a bool.
84
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +000085- Issue #4597: Fixed several opcodes that weren't always propagating

89 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
90 str instances. On a typical machine this saves 3 bytes of memory
91 (on average) per string allocation.
92
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +000093- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

102
Vinay Sajip213faca2008-12-03 23:22:58 +0000103- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000104 method on file objects with closefd=False. The file descriptor is still
105 kept open but the file object behaves like a closed file. The ``FileIO``
106 object also got a new readonly attribute ``closefd``.
107
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000108- Issue #4348: Some bytearray methods returned that didn't cause any change to
109 the bytearray, returned the same bytearray instead of a copy.
110
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000111- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
112
Benjamin Peterson273c2332008-11-17 22:39:09 +0000113- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
114
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000115- Issue #4048: The parser module now correctly validates relative imports.
116
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000117- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
118 exec statement.
119
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000120- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
121 method does not return iterators for the 4th and 5th items.
122
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000123- Issue #4209: Enabling unicode_literals and the print_function in the same
124 __future__ import didn't work.
125
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000126- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000127 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000128
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000129- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
130 returned a path longer than MAX_PATH. (But It's doubtful this code path is
131 really executed because I cannot move to such directory on win2k)
132
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000133- Issue #4069: When set.remove(element) is used with a set element, the element
134 is temporarily replaced with an equivalent frozenset. But the eventual
135 KeyError would always report the empty frozenset([]) as the missing key. Now
136 it correctly refers to the initial element.
137
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000138- Issue #4509: Various issues surrounding resize of bytearray objects to
139 which there are buffer exports.
140
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000141- Issue #4748: Lambda generators no longer return a value.
142

149 allow adding directories to a zipfile.
150
Jesse Nollerf6da8d12009-01-23 14:04:41 +0000151- Issue #3807: _multiprocessing build fails when configure is passed
152 --without-threads argument. When this occurs, _multiprocessing will
153 be disabled, and not compiled.
154
Antoine Pitroue741cc62009-01-21 00:45:36 +0000155- Issue #5008: When a file is opened in append mode with the new IO library,
156 do an explicit seek to the end of file (so that e.g. tell() returns the
157 file size rather than 0). This is consistent with the behaviour of the
158 traditional 2.x file object.
159
Vinay Sajip5fb11b22009-01-20 22:43:17 +0000160- Issue #5013: Fixed a bug in FileHandler which occurred when the delay
161 parameter was set.
162
Raymond Hettinger933d3a72009-01-20 20:34:19 +0000163- Issue #4998: The memory saving effect of __slots__ had been lost on Fractions
164 which inherited from numbers.py which did not have __slots__ defined. The
165 numbers heirarchy now has its own __slots__ declarations.
166
Jesse Noller9a5b2ad2009-01-19 15:12:22 +0000167- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks
168 for *nix machines for negative handles and large int handles. Without this check
169 it is possible to segfault the interpreter.
170
Jesse Noller6ab22152009-01-18 02:45:38 +0000171- Issue #4449: AssertionError in mp_benchmarks.py, caused by an underlying issue

178 opened with other applications.
179
Amaury Forgeot d'Arcb54447f2009-01-13 23:39:22 +0000180- Issue #1162154: inspect.getmembers() now skips attributes that raise
181 AttributeError, e.g. a __slots__ attribute which has not been set.
182
183- Issue #1696199: Add collections.Counter() for rapid and convenient
Raymond Hettingerf94d7fa2009-01-12 22:58:41 +0000184 counting.
185
Antoine Pitroubd4b5f22009-01-10 16:15:24 +0000186- Issue #3860: GzipFile and BZ2File now support the context manager protocol.

189 the timestamp in the gzip stream. The default value remains the current time.
190 The information can be used by e.g. gunzip when decompressing. Patch by
191 Jacques Frechet.

Raymond Hettingerf4d85972009-01-03 19:02:23 +0000202- Issue #4796: Added Decimal.from_float() and Context.create_decimal_from_float()
203 to the decimal module.
204
Mark Dickinsonc5de0962009-01-02 23:07:08 +0000205- Issue #4812: add missing underscore prefix to some internal-use-only

207
Benjamin Peterson8ad09a42008-12-31 23:48:39 +0000208- Issue #4795: inspect.isgeneratorfunction() returns False instead of None when
209 the function is not a generator.
210
Vinay Sajip5fb11b22009-01-20 22:43:17 +0000211- Issue #4702: Throwing a DistutilsPlatformError instead of IOError in case

504
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000505- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
506 PyString_FromFormat or PyErr_Format to display size_t values. The macro
507 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
508 ``printf`` function, whereas PyString_FromFormat has an independent
509 implementation and uses "%zd" on all platforms for size_t values.
510 This makes a difference on win64, where ``printf`` needs "%Id" to display
511 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000531 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
532 mechanism. In the process, fix a bug where isinstance() and issubclass(),

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000674What's New in Python 2.6 beta 3?
675================================
676
Barry Warsaw07a4a382008-08-21 01:15:08 +0000677*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000678
679Core and Builtins
680-----------------
681
Guido van Rossumf8402962008-08-20 15:01:50 +0000682- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
683 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
684 extensions do not automatically benefit from the class attribute
685 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
686 to their tp_flags field if they care. This is a backwards
687 compatibility feature; in 3.0, all types will use the cache by
688 default.
689
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000690- Keyword arguments can now follow starred arguments. (``f(a, *args,
691 keyword=23)`` is now valid syntax.)
692
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000693- ctypes function pointers that are COM methods have a boolean True
694 value again.
695
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000696- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
697 by denying s# to parse objects that have a releasebuffer procedure,
698 and introducing s*.
699
Georg Brandl1e13ea92008-08-11 09:07:59 +0000700- Issue #3537: Fix an assertion failure when an empty but presized dict
701 object was stored in the freelist.
702
Mark Dickinsonb6467572008-08-04 21:30:09 +0000703- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
704 ValueError consistently across platforms.
705
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000706- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
707 (64bit Unix, for example), unichr() would truncate its argument and return
708 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
709
Neal Norwitze7d8be82008-07-31 17:17:14 +0000710- Apply security patches from Apple.
711
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000712- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
713 PyErr_ExceptionMatches returns 0 when an exception occurs there.
714
Antoine Pitrou92f82162008-07-25 22:22:08 +0000715- Issue #1819: function calls with several named parameters are now on
716 average 35% faster (as measured by pybench).
717
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000718- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
719 the python debugger steps into a class statement: the free variables (local
720 variables defined in an outer scope) would be deleted from the outer scope.
721
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000722- Issue #2620: Overflow checking when allocating or reallocating memory
723 was not always being done properly in some python types and extension
724 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
725 all been updated to perform better checks and places in the code that
726 would previously leak memory on the error path when such an allocation
727 failed have been fixed.
728
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000729Library
730-------
731

Benjamin Petersone977ad42008-08-20 01:42:01 +0000734- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
735 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
736
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000737- Issue #2234: distutils failed for some versions of the cygwin compiler. The
738 version reported by these tools does not necessarily follow the python
739 version numbering scheme, so the module is less strict when parsing it.
740
Nick Coghlanf70385a2008-08-18 12:42:46 +0000741- Issue #2235: Added Py3k warnings for types which will become unhashable
742 under the stricter __hash__ inheritance rules in 3.0. Several types
743 which did not meet the rules for hash invariants and were already
744 unhashable in 3.0 have now been explicitly flagged as unhashable in
745 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
746 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
747
Brett Cannon88f801d2008-08-18 00:46:22 +0000748- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

756
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000757- Issue #3575: Incremental decoder's decode function now takes bytearray
758 by using 's*' instead of 't#'.
759
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000760- Issue #2222: Fixed reference leak when occured os.rename()
761 fails unicode conversion on 2nd parameter. (windows only)
762
Facundo Batista94f243a2008-08-17 03:38:39 +0000763- Issue 2464. urllib2 now supports a malformation in the URL received
764 in a redirect.
765
Brett Cannonabe423e2008-08-16 21:47:07 +0000766- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000767 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000768
Facundo Batistaeb90b782008-08-16 14:44:07 +0000769- Issue #2776: fixed small issue when handling an URL with double slash
770 after a 302 response in the case of not going through a proxy.
771
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000772- Issue #2676: in the email package, content-type parsing was hanging on
773 pathological input because of quadratic or exponential behaviour of a
774 regular expression.
775
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000776- Issue #3476: binary buffered reading through the new "io" library is now
777 thread-safe.
778
Brett Cannonbf3157b2008-08-14 05:00:03 +0000779- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
780 since mimetools itself is deprecated. Because modules are cached, all
781 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
782
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000783- Issue #3134: shutil referenced undefined WindowsError symbol.
784
Robert Schuppenies14646332008-08-10 11:01:53 +0000785- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
786 menu entries were not deleted.
787
Brett Cannon83e81842008-08-09 23:30:55 +0000788- Copied the implementation of reduce() to _functools.reduce() to have a
789 version that did not raise a DeprecationWarning under -3.
790
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000791- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
792 a MemoryError rather than silently stop the iteration.
793
Guido van Rossum59ce9012008-08-09 14:55:34 +0000794- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
795 to _sre.compile() will now be rejected. This should not affect anybody
796 since the re.compile() function never generates invalid re-bytecode.
797
Skip Montanaroa032bf42008-08-08 22:52:51 +0000798- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
799 upon first access it can be automatically initialized from the csv file if
800 it wasn't initialized during instantiation.
801
Brett Cannon3aa2a492008-08-06 22:28:09 +0000802- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
803 the reload() built-in has been removed.
804
Brett Cannon7e30b672008-08-04 21:52:25 +0000805- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +0000806 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

808 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
809 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
810 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
811 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +0000812
Lars Gustäbel727bd0b2008-08-02 11:26:39 +0000813- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
814 raised an AttributeError.
815
Benjamin Peterson01a24322008-07-28 23:35:27 +0000816- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +0000817 asking for a specific length. This problem only affected files opened
818 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000819

842
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000843- Issue #3394: zipfile.writestr sets external attributes when passed a
844 file name rather than a ZipInfo instance, so files are extracted with
845 mode 0600 rather than 000 under Unix.
846
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000847- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
848 argument in python 2.5, this broke code that subclassed Popen to include its
849 own poll method. Fixed my moving _deadstate to an _internal_poll method.
850

857-------------
858
Nick Coghlan6e8fef02008-08-18 13:14:22 +0000859- Issue #2235: the C API function PyObject_HashNotImplemented and its
860 interaction with the tp_hash slot (added in 2.6b2) are now documented

864 regarding lack of coverage of new-style classes have also been
865 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000868What's New in Python 2.6 beta 2?
869================================
870
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000871*Release date: 17-Jul-2008*
872
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000873Core and Builtins
874-----------------
875
Georg Brandl3e483f62008-07-16 22:57:41 +0000876- Issue #3156: Fix inconsistent behavior of the bytearray type: all
877 its methods now allow for items objects that can be converted to
878 an integer using operator.index().
879
Mark Dickinson64b7e502008-07-16 09:40:03 +0000880- Issue #3360: Fix incorrect parsing of '020000000000.0', which
881 produced a ValueError instead of giving the correct float.
882
Eric Smitha5fa5a22008-07-16 00:11:49 +0000883- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
884 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
885
Mark Dickinson7103aa42008-07-15 19:08:33 +0000886- Issue #3008: the float type has a new instance method 'float.hex'
887 and a new class method 'float.fromhex' to convert floating-point
888 numbers to and from hexadecimal strings, respectively.
889
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000890- Issue #2235: __hash__ is once again inherited by default. To allow
891 collections.Hashable to remain meaningful in the presence of the
892 default hash implementation (object.__hash__), it is now possible
893 to explicit block inheritance of hash by setting __hash__=None at
894 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
895 level.
896
Nick Coghlanb028f502008-07-13 14:52:36 +0000897- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
898 the parent module cannot be found while performing an absolute import.
899 This means that an incorrectly defined __package__ attribute will
900 now only prevent relative imports in that module rather than causing
901 all imports from that module to fail.
902
Nick Coghlan14ff9942008-07-08 14:21:42 +0000903- Issue #2517: Allow unicode messages in Exceptions again by correctly
904 bypassing the instance dictionary when looking up __unicode__ on
905 new-style classes.
906
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000907- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
908 set to a custom object whose write() method happens to install
909 another file in sys.stdout.
910
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000911- Issue #3088: Corrected a race condition in classes derived from
912 threading.local: the first member set by a thread could be saved in
913 another thread's dictionary.
914
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000915- Issue #3004: Minor change to slice.indices(): the start and stop
916 arguments are now treated identically, making the behaviour easier

1373 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001374 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001375
1376 This is controlled by the configure argument ``--with-universal-archs``:
1377
1378 - ``--with-universal-archs=all``: install 4-way universal
1379
1380 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1381
1382 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1383
1384 This option should be used in combination with ``--enable-universalsdk=``.

1423 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00001424
Christian Heimese74c8f22008-04-19 02:23:57 +00001425- Added kill, terminate and send_signal(sig) to subprocess.Popen.
1426

Georg Brandl3ee81df2008-05-17 18:14:43 +00001436- Issue #1631171: Re-implement the 'warnings' module in C (the
1437 original Python code has been kept as backup). This will allow for
1438 using the 'warning's machinery in such places as the parser where
1439 use of pure Python code is not possible. Both the ``showarning()``
1440 and ``formatwarning()`` gain an optional 'line' argument which is
1441 not called by default for backwards-compatibility reasons. Setting
1442 ``warnings.showwarning()`` to an implementation that lacks support
1443 for the ``line`` argument will raise a DeprecationWarning.

1467
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001468- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00001506- Issue #2550: The approach used by client/server code for obtaining
1507 ports to listen on in network-oriented tests has been refined in an
1508 effort to facilitate running multiple instances of the entire
1509 regression test suite in parallel without issue.
1510 test_support.bind_port() has been fixed such that it will always
1511 return a unique port -- which wasn't always the case with the
1512 previous implementation, especially if socket options had been set
1513 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1514 new implementation of bind_port() will actually raise an exception
1515 if it is passed an AF_INET/SOCK_STREAM socket with either the
1516 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1517 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1518 the socket it's been passed. This currently only applies to
1519 Windows. This option prevents any other sockets from binding to the
1520 host/port we've bound to, thus removing the possibility of the
1521 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1522 when a second SOCK_STREAM socket binds and accepts to a host/port
1523 that's already been bound by another socket. The optional preferred
1524 port parameter to bind_port() has been removed. Under no
1525 circumstances should tests be hard coding ports!
1526
1527 test_support.find_unused_port() has also been introduced, which will
1528 pass a temporary socket object to bind_port() in order to obtain an
1529 unused port. The temporary socket object is then closed and
1530 deleted, and the port is returned. This method should only be used
1531 for obtaining an unused port in order to pass to an external program
1532 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1533 a parameter to a server-oriented class that doesn't give you direct
1534 access to the underlying socket used.
1535
1536 Finally, test_support.HOST has been introduced, which should be used
1537 for the host argument of any relevant socket calls (i.e. bind and
1538 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001539
1540 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001541 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001542 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1543 test_asynchat and test_socket_ssl.
1544
Georg Brandl3ee81df2008-05-17 18:14:43 +00001545 It is now possible for multiple instances of the regression test
1546 suite to run in parallel without issue.

1813-----------------
1814
Fred Drakea8ee94b2008-03-01 02:45:07 +00001815- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001816 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001817
Georg Brandlad61bc82008-02-23 15:11:18 +00001818- Issue #2067: file.__exit__() now calls subclasses' close() method.
1819
1820- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001821
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001822- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001823 issue 215555 for a discussion.
1824
Eric Smitha73fbe72008-02-23 03:09:44 +00001825- Added the future_builtins module, which contains hex() and oct().
1826 These are the PEP 3127 version of these functions, designed to be
1827 compatible with the hex() and oct() builtins from Python 3.0. They
1828 differ slightly in their output formats from the existing, unchanged
1829 Python 2.6 builtins. The expected usage of the future_builtins
1830 module is:
1831 from future_builtins import hex, oct
1832
Eric Smith7ef40bf2008-02-20 23:34:22 +00001833- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1834 exponents for exponents with absolute value < 100. Follows C99
1835 standard. This is a change on Windows, which would use 3 digits.
1836 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1837 so that any alterations it does to the resulting string will be
1838 available in stringlib/formatter.h (for float.__format__).
1839
Eric Smith5a3c1352008-02-19 13:21:56 +00001840- Implemented PEP 3101, Advanced String Formatting. This adds a new
1841 builtin format(); a format() method for str and unicode; a
1842 __format__() method to object, str, unicode, int, long, float, and
1843 datetime; the class string.Formatter; and the C API
1844 PyObject_Format().
1845
Georg Brandl3ee81df2008-05-17 18:14:43 +00001846- Fixed several potential crashes, all caused by specially crafted
1847 __del__ methods exploiting objects in temporarily inconsistent
1848 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001849
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001850- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001851 prevent a possible crash: an Abstract Base Class would try to access
1852 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001853
Georg Brandl3ee81df2008-05-17 18:14:43 +00001854- Fixed repr() and str() of complex numbers with infinity or nan as
1855 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001856
Georg Brandl3ee81df2008-05-17 18:14:43 +00001857- Clear all free lists during a gc.collect() of the highest generation
1858 in order to allow pymalloc to free more arenas. Python may give back
1859 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001860
Georg Brandl3ee81df2008-05-17 18:14:43 +00001861- Issue #2045: Fix an infinite recursion triggered when printing a
1862 subclass of collections.defaultdict, if its default_factory is set
1863 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001864
Christian Heimesf75dbef2008-02-08 00:11:31 +00001865- Fixed a minor memory leak in dictobject.c. The content of the free
1866 list was not freed on interpreter shutdown.
1867
Georg Brandl3ee81df2008-05-17 18:14:43 +00001868- Limit free list of method and builtin function objects to 256
1869 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001870
Georg Brandl3ee81df2008-05-17 18:14:43 +00001871- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1872 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001873 to compact the internal free lists of pre-allocted ints and floats.
1874
Georg Brandl3ee81df2008-05-17 18:14:43 +00001875- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1876 calls. Python expected the return type int but the fork familie
1877 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001878
Georg Brandl3ee81df2008-05-17 18:14:43 +00001879- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1880 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001881
Georg Brandl3ee81df2008-05-17 18:14:43 +00001882- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1883 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00001884
Georg Brandl3ee81df2008-05-17 18:14:43 +00001885- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
1886 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00001888- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1889 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001890
Georg Brandl3ee81df2008-05-17 18:14:43 +00001891- Patch #1473257: generator objects gain a gi_code attribute. This is
1892 the same object as the func_code attribute of the function that
1893 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001894
Georg Brandl3ee81df2008-05-17 18:14:43 +00001895- Issue #1920: "while 0" statements were completely removed by the
1896 compiler, even in the presence of an "else" clause, which is
1897 supposed to be run when the condition is false. Now the compiler
1898 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001899
Guido van Rossumeead05f2008-01-24 18:21:02 +00001900- A few crashers fixed: weakref_in_del.py (issue #1377858);
1901 loosing_dict_ref.py (issue #1303614, test67.py);
1902 borrowed_ref_[34].py (not in tracker).
1903
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001904- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001905 suppressed while an extension is loaded by calling SetErrorMode in
1906 dynload_win.c. The error is still reported properly.
1907
Georg Brandl3ee81df2008-05-17 18:14:43 +00001908- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001909 several extension methods and modules do not work without unicode
1910 support.
1911
Georg Brandl26543b12008-01-21 18:36:51 +00001912- Issue #1882: when compiling code from a string, encoding cookies in the
1913 second line of code were not always recognized correctly.
1914
Georg Brandl14404b62008-01-19 19:27:05 +00001915- Issue #1679: "0x" was taken as a valid integer literal.
1916
Georg Brandl6caad7d2008-01-26 14:19:22 +00001917- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001918 added.
1919
Christian Heimesc94e2b52008-01-14 04:13:37 +00001920- sys.float_info / PyFloat_GetInfo: The floating point information
1921 object was converted from a dict to a specialized structseq object.
1922
Georg Brandl3ee81df2008-05-17 18:14:43 +00001923- Patch #1816: Added sys.flags structseq. It exposes the status of
1924 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001925
Georg Brandl3ee81df2008-05-17 18:14:43 +00001926- Objects/structseq.c: Implemented new structseq representation. The
1927 patch makes structseqs (e.g. the return value of os.stat) more
1928 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001929
Georg Brandl3ee81df2008-05-17 18:14:43 +00001930- Patch #1700288: added a type attribute cache that caches method
1931 accesses, resulting in speedups in heavily object-oriented code.

1940 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00001941
Georg Brandl3ee81df2008-05-17 18:14:43 +00001942- Improve some exception messages when Windows fails to load an
1943 extension module. Now we get for example '%1 is not a valid Win32
1944 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00001951- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00001952 and INF. float("nan"), float("inf") and float("-inf") now work on
1953 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001954
Georg Brandl3ee81df2008-05-17 18:14:43 +00001955- Compiler now generates simpler and faster code for dictionary
1956 literals. The oparg for BUILD_MAP now indicates an estimated
1957 dictionary size. There is a new opcode, STORE_MAP, for adding
1958 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001987- Patch #1739468: Directories and zipfiles containing a __main__.py
1988 file can now be directly executed by passing their name to the
1989 interpreter. The directory/zipfile is automatically inserted as the
1990 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00001991
Georg Brandl3ee81df2008-05-17 18:14:43 +00001992- Issue #1265: Fix a problem with sys.settrace, if the tracing
1993 function uses a generator expression when at the same time the
1994 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00001995
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00001996- sets and frozensets now have an isdisjoint() method.

2001
Georg Brandl3ee81df2008-05-17 18:14:43 +00002002- The enumerate() builtin function is no longer bounded to sequences
2003 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2004 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002005
Georg Brandl3ee81df2008-05-17 18:14:43 +00002006- Issue #1686386: Tuple's tp_repr did not take into account the
2007 possibility of having a self-referential tuple, which is possible
2008 from C code. Nor did object's tp_str consider that a type's tp_str
2009 could do something that could lead to an inifinite recursion.
2010 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2011 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002012
Georg Brandl3ee81df2008-05-17 18:14:43 +00002013- Issue #1164: It was possible to trigger deadlock when using the
2014 'print' statement to write to a file since the GIL was not released
2015 as needed. Now PyObject_Print() does the right thing along with
2016 various tp_print implementations of the built-in types and those in
2017 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002018
Georg Brandl3ee81df2008-05-17 18:14:43 +00002019- Issue #1147: Exceptions were directly allowing string exceptions in
2020 their throw() method even though string exceptions no longer
2021 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002022
Georg Brandl3ee81df2008-05-17 18:14:43 +00002023- Issue #1096: Prevent a segfault from getting the repr of a very
2024 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002025
Brett Cannon1e534b52007-09-07 04:18:30 +00002026- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002027 PyObject_Call() never calling back out to Python code to trigger
2028 recursion depth updates/checks. Required the creation of a static
2029 RuntimeError instance in case normalizing an exception put the
2030 recursion check value past its limit. Fixes crashers
2031 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002032

Neal Norwitz0ac60192007-05-27 04:08:54 +00002046- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002047 __*__ attributes. (Some already existed, e.g., __doc__ and
2048 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002049
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002050- Add -3 option to the interpreter to warn about features that are
2051 deprecated and will be changed/removed in Python 3.0.
2052
Georg Brandl2134e752007-05-21 20:34:16 +00002053- Patch #1686487: you can now pass any mapping after '**' in function
2054 calls.
2055
Collin Winter62903052007-05-18 23:11:24 +00002056- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002057 "except E as target:". This is to provide forwards compatibility
2058 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002059
Brett Cannon229cee22007-05-05 01:34:02 +00002060- Deprecate BaseException.message as per PEP 352.
2061
Georg Brandl3ee81df2008-05-17 18:14:43 +00002062- Issue #1303614: don't expose object's __dict__ when the dict is

2064
Vinay Sajip8549ce32007-05-06 17:53:37 +00002065- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002066 setting a plain string, ie don't expand to single letter identifiers.
2067
Raymond Hettinger13936692007-04-11 18:40:58 +00002068- Request #1191699: Slices can now be pickled.
2069
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002070- Request #1193128: str.translate() now allows a None argument for
2071 translations that only remove characters without re-mapping the
2072 remaining characters.
2073
Georg Brandl5cb76c12007-03-21 09:00:39 +00002074- Patch #1682205: a TypeError while unpacking an iterable is no longer

2076
Neal Norwitzaa754b72007-03-21 06:39:48 +00002077- Remove unused file Python/fmod.c.
2078
Guido van Rossum143b5642007-03-23 04:58:42 +00002079- Bug #1683368: The object.__init__() and object.__new__() methods are
2080 now stricter in rejecting excess arguments. The only time when
2081 either allows excess arguments is when it is not overridden and the
2082 other one is. For backwards compatibility, when both are
2083 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002084 warning later). Also, type.__init__() insists on the same signature
2085 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002086
Georg Brandl3ee81df2008-05-17 18:14:43 +00002087- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2088 object to complex using its __complex__() method before falling back
2089 to the __float__() method. Therefore, the functions in the cmath
2090 module now can operate on objects that define a __complex__()
2091 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002092
Georg Brandl3ee81df2008-05-17 18:14:43 +00002093- Patch #1623563: allow __class__ assignment for classes with
2094 __slots__. The old and the new class are still required to have the
2095 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002096

2101 ``object.__reduce_ex__()`` is called with an object that is faking
2102 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002103
Georg Brandl3ee81df2008-05-17 18:14:43 +00002104- Patch #1680015: Don't modify __slots__ tuple if it contains an

2108
Georg Brandl7b9c5552007-03-12 14:30:05 +00002109- Bug #1678647: write a newline after printing an exception in any
2110 case, even when converting the value to a string failed.
2111
Georg Brandl871f1bc2007-03-12 13:17:36 +00002112- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002113 its argument, if it exists. If not, it will work like before. This
2114 allows customizing the output of dir() in the presence of a
2115 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002116
Collin Winter276887b2007-03-12 16:11:39 +00002117- Patch #922167: Python no longer segfaults when faced with infinitely
2118 self-recursive reload() calls (as reported by bug #742342).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002123- Patch #1491866: change the complex() constructor to allow
2124 parthensized forms. This means complex(repr(x)) now works instead of
2125 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002126
Georg Brandlaa2321b2007-03-07 00:40:28 +00002127- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002128 makes the filenames the warning module prints much more sensible
2129 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002130
Georg Brandl49aafc92007-03-07 00:34:46 +00002131- Variant of patch #697613: don't exit the interpreter on a SystemExit
2132 exception if the -i command line option or PYTHONINSPECT environment

Georg Brandl0fca97a2007-03-05 22:28:08 +00002142- Patch #1674228: when assigning a slice (old-style), check for the
2143 sq_ass_slice instead of the sq_slice slot.
2144
Georg Brandl3ee81df2008-05-17 18:14:43 +00002145- When printing an unraisable error, don't print exceptions. before
2146 the name. This duplicates the behavior whening normally printing
2147 exceptions.

2204
Armin Rigo7ccbca92006-10-04 12:17:45 +00002205- A number of places, including integer negation and absolute value,

2772 TestCase and TestSuite subclasses (not instances) are no longer
2773 accepted in TestSuite.addTest(). This should cause no

2775 -- the failure just occurred later, with a more cumbersome
2776 exception.

3060 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003061
Georg Brandl3ee81df2008-05-17 18:14:43 +00003062- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003063 that the SMTP.starttls() caller no longer needs to call ehlo()
3064 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003065 does not claim to support starttls. Adds the
3066 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3147 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3148 silently miscode subclasses of those types. Now, it raises a
3149 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003150

Georg Brandl3ee81df2008-05-17 18:14:43 +00003165 time so that opening a database previously created with the DB_DUP
3166 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3167 opens. Specifically: dictionary assignment to a DB object will
3168 replace all values for a given key when the database allows
3169 duplicate values. DB users should use DB.put(k, v) when they want
3170 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003171

3177 characters with ASCII value less than 32. Also, it correctly quotes
3178 dots only if they occur on a single line, as opposed to the previous
3179 behavior of quoting dots if they are the second character of any
3180 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003181

3503-----
3504
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505- Unified naming convention for free lists and their limits. All free
3506 lists in Object/ are named ``free_list``, the counter ``numfree``
3507 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3508 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003509
Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3511 to ``PyTuple_SetItem``, it can be used to populate a brand new
3512 frozenset; but it does not steal a reference to the added item.

3524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3526 of w# format code incorrectly truncated the length to an int, even
3527 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3528 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003529
Georg Brandl3ee81df2008-05-17 18:14:43 +00003530- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3547
3548- Fix some leftovers from the conversion from int to Py_ssize_t
3549 (relevant to strings and sequences of more than 2**31 items).
3550
3551- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3552 outside of pystate.c and should not be necessary.
3553
Georg Brandl3ee81df2008-05-17 18:14:43 +00003554- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3555 absolute imports. In earlier versions they might have used relative
3556 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003557
Georg Brandl3ee81df2008-05-17 18:14:43 +00003558- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3559 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003560
Georg Brandl3ee81df2008-05-17 18:14:43 +00003561- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003568- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3569 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3570 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3571 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003572

3585
Georg Brandl3ee81df2008-05-17 18:14:43 +00003586- Removed the macfs module. It had been deprecated since Python 2.5.
3587 This lead to the deprecation of macostools.touched() as it relied
3588 solely on macfs and was a no-op under OS X.
