890 302 conformant loader) will now work correctly in most cases (they
891 are still subject to the constraints that exist for all code running
892 from inside a module loaded via a PEP 302 loader and attempting to

1051What's New in Python 2.6.1
1052==========================
1053
1054*Release date: 04-Dec-2008*
1055
1056Core and Builtins
1057-----------------
1058
1059- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1060 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1061 instead of throwing a MemoryError.
1062
1063- Issue #4367: Python would segfault during compiling when the unicodedata
1064 module couldn't be imported and \N escapes were present.
1065
1066- Issue #4348: Some bytearray methods returned that didn't cause any change to
1067 the bytearray, returned the same bytearray instead of a copy.
1068
1069- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1070
1071- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1072
1073- Issue #4048: The parser module now correctly validates relative imports.
1074
1075- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1079 method does not return iterators for the 4th and 5th items.
1080
1081- Issue #4209: Enabling unicode_literals and the print_function in the same
1082 __future__ import didn't work.
1083
1084- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1085 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1086 really executed because I cannot move to such directory on win2k)
1087
1088- Issue #4069: When set.remove(element) is used with a set element, the element
1089 is temporarily replaced with an equivalent frozenset. But the eventual
1090 KeyError would always report the empty frozenset([]) as the missing key. Now
1091 it correctly refers to the initial element.
1092
1093- Fixed C99 style comments in several files. Python is now C89 compatible
1094 again.

1242
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001243- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1244 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1245 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1246 ``printf`` function, whereas PyString_FromFormat has an independent
1247 implementation and uses "%zd" on all platforms for size_t values.
1248 This makes a difference on win64, where ``printf`` needs "%Id" to display
1249 64bit values.

1270 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1272 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1273 type object.

1344 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1345 for catch_warnings() also led to an improvement in the raising of a

1367
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001368- Issue #2975: When compiling several extension modules with Visual Studio 2008
1369 from the same python interpreter, some environment variables would grow
1370 without limit.
1371
Benjamin Peterson37346b22008-08-23 20:27:43 +00001372- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001409What's New in Python 2.6 beta 3?
1410================================
1411
Barry Warsaw07a4a382008-08-21 01:15:08 +00001412*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001413
1414Core and Builtins
1415-----------------
1416
Guido van Rossumf8402962008-08-20 15:01:50 +00001417- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1418 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1419 extensions do not automatically benefit from the class attribute
1420 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1421 to their tp_flags field if they care. This is a backwards
1422 compatibility feature; in 3.0, all types will use the cache by
1423 default.
1424
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001425- Keyword arguments can now follow starred arguments. (``f(a, *args,
1426 keyword=23)`` is now valid syntax.)
1427
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001428- ctypes function pointers that are COM methods have a boolean True
1429 value again.
1430
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001431- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1432 by denying s# to parse objects that have a releasebuffer procedure,
1433 and introducing s*.
1434
Georg Brandl1e13ea92008-08-11 09:07:59 +00001435- Issue #3537: Fix an assertion failure when an empty but presized dict
1436 object was stored in the freelist.
1437
Mark Dickinsonb6467572008-08-04 21:30:09 +00001438- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1439 ValueError consistently across platforms.
1440
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001441- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1442 (64bit Unix, for example), unichr() would truncate its argument and return
1443 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1444
Neal Norwitze7d8be82008-07-31 17:17:14 +00001445- Apply security patches from Apple.
1446
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001447- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1448 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1449
Antoine Pitrou92f82162008-07-25 22:22:08 +00001450- Issue #1819: function calls with several named parameters are now on
1451 average 35% faster (as measured by pybench).
1452
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001453- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1454 the python debugger steps into a class statement: the free variables (local
1455 variables defined in an outer scope) would be deleted from the outer scope.
1456
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001457- Issue #2620: Overflow checking when allocating or reallocating memory
1458 was not always being done properly in some python types and extension
1459 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1460 all been updated to perform better checks and places in the code that
1461 would previously leak memory on the error path when such an allocation
1462 failed have been fixed.
1463
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001464Library
1465-------
1466
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001467- Issue #3612: Added some missing basic types in ctypes.wintypes.
1468
Benjamin Petersone977ad42008-08-20 01:42:01 +00001469- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1470 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1471
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001472- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1473 version reported by these tools does not necessarily follow the python
1474 version numbering scheme, so the module is less strict when parsing it.
1475
Nick Coghlanf70385a2008-08-18 12:42:46 +00001476- Issue #2235: Added Py3k warnings for types which will become unhashable
1477 under the stricter __hash__ inheritance rules in 3.0. Several types
1478 which did not meet the rules for hash invariants and were already
1479 unhashable in 3.0 have now been explicitly flagged as unhashable in
1480 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1481 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1482
Brett Cannon88f801d2008-08-18 00:46:22 +00001483- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1487
Brett Cannon46225e72008-08-18 00:36:52 +00001488- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1491
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001492- Issue #3575: Incremental decoder's decode function now takes bytearray
1493 by using 's*' instead of 't#'.
1494
Jesus Cea585ad8a2009-07-02 15:37:21 +00001495- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001496 fails unicode conversion on 2nd parameter. (windows only)
1497
Facundo Batista94f243a2008-08-17 03:38:39 +00001498- Issue 2464. urllib2 now supports a malformation in the URL received
1499 in a redirect.
1500
Brett Cannonabe423e2008-08-16 21:47:07 +00001501- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001502 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001503
Facundo Batistaeb90b782008-08-16 14:44:07 +00001504- Issue #2776: fixed small issue when handling an URL with double slash
1505 after a 302 response in the case of not going through a proxy.
1506
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001507- Issue #2676: in the email package, content-type parsing was hanging on
1508 pathological input because of quadratic or exponential behaviour of a
1509 regular expression.
1510
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001511- Issue #3476: binary buffered reading through the new "io" library is now
1512 thread-safe.
1513
Brett Cannonbf3157b2008-08-14 05:00:03 +00001514- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1515 since mimetools itself is deprecated. Because modules are cached, all
1516 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1517
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001518- Issue #3134: shutil referenced undefined WindowsError symbol.
1519
Robert Schuppenies14646332008-08-10 11:01:53 +00001520- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1521 menu entries were not deleted.
1522
Brett Cannon83e81842008-08-09 23:30:55 +00001523- Copied the implementation of reduce() to _functools.reduce() to have a
1524 version that did not raise a DeprecationWarning under -3.
1525
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001526- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1527 a MemoryError rather than silently stop the iteration.
1528
Guido van Rossum59ce9012008-08-09 14:55:34 +00001529- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1530 to _sre.compile() will now be rejected. This should not affect anybody
1531 since the re.compile() function never generates invalid re-bytecode.
1532
Skip Montanaroa032bf42008-08-08 22:52:51 +00001533- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1534 upon first access it can be automatically initialized from the csv file if
1535 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00001537- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1538 the reload() built-in has been removed.
1539
Brett Cannon7e30b672008-08-04 21:52:25 +00001540- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001541 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001552 asking for a specific length. This problem only affected files opened
1553 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001554

1579 file name rather than a ZipInfo instance, so files are extracted with
1580 mode 0600 rather than 000 under Unix.
1581
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001582- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1595 interaction with the tp_hash slot (added in 2.6b2) are now documented
1596
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001597- Issue #643841: The language reference now provides more detailed
1598 coverage of the lookup process for special methods. The disclaimers
1599 regarding lack of coverage of new-style classes have also been
1600 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001603What's New in Python 2.6 beta 2?
1604================================
1605
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001606*Release date: 17-Jul-2008*
1607
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001608Core and Builtins
1609-----------------
1610
Georg Brandl3e483f62008-07-16 22:57:41 +00001611- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1612 its methods now allow for items objects that can be converted to
1613 an integer using operator.index().
1614
Mark Dickinson64b7e502008-07-16 09:40:03 +00001615- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1616 produced a ValueError instead of giving the correct float.
1617
Eric Smitha5fa5a22008-07-16 00:11:49 +00001618- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1619 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1620
Mark Dickinson7103aa42008-07-15 19:08:33 +00001621- Issue #3008: the float type has a new instance method 'float.hex'
1622 and a new class method 'float.fromhex' to convert floating-point
1623 numbers to and from hexadecimal strings, respectively.
1624
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001625- Issue #2235: __hash__ is once again inherited by default. To allow
1626 collections.Hashable to remain meaningful in the presence of the
1627 default hash implementation (object.__hash__), it is now possible
1628 to explicit block inheritance of hash by setting __hash__=None at
1629 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1630 level.
1631
Nick Coghlanb028f502008-07-13 14:52:36 +00001632- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1633 the parent module cannot be found while performing an absolute import.
1634 This means that an incorrectly defined __package__ attribute will
1635 now only prevent relative imports in that module rather than causing
1636 all imports from that module to fail.
1637
Nick Coghlan14ff9942008-07-08 14:21:42 +00001638- Issue #2517: Allow unicode messages in Exceptions again by correctly
1639 bypassing the instance dictionary when looking up __unicode__ on
1640 new-style classes.
1641
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001642- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1643 set to a custom object whose write() method happens to install
1644 another file in sys.stdout.
1645
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001646- Issue #3088: Corrected a race condition in classes derived from
1647 threading.local: the first member set by a thread could be saved in
1648 another thread's dictionary.
1649
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001650- Issue #3004: Minor change to slice.indices(): the start and stop
1651 arguments are now treated identically, making the behaviour easier
1652 to describe and understand. For example, slice(None, -10,
1653 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1654 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1655 10, -1).
1656
Georg Brandl278fc502008-07-19 12:46:12 +00001657- Issue #3219: Calling a function with repeated keyword arguments,
1658 f(a=2, a=23), would not cause a syntax error. This was a regression
1659 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001660
Georg Brandl278fc502008-07-19 12:46:12 +00001661- Issue #2862: Make int and float freelist management consistent with
1662 other freelists. Changes their CompactFreeList apis into
1663 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001664

1666-------
1667
Thomas Heller57adf222008-08-14 19:10:48 +00001668- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1669 api functions without holding the GIL, which could lead to a fatal
1670 error when they failed.
1671
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001672- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1679
Jesse Noller13e9d582008-07-16 14:32:36 +00001680- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1681 ForkingPickler.register() to resolve conflict with ctypes.
1682
Vinay Sajip51e65192008-07-18 09:01:10 +00001683- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001684
Thomas Heller880f5292008-07-15 19:39:38 +00001685- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1686 a valid dlerror() message.
1687
Thomas Heller2bad6572008-07-15 17:19:50 +00001688- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1689 incomplete structure was created.
1690
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001691- Issue #3339: dummy_thread.acquire() should not return None.
1692
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001693- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1694
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001695- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001696
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001697- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1698 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001699 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001700 content-length. The problem had been corrected in the 2.4 branch, but never
1701 merged into trunk.
1702
Georg Brandle78fbcc2008-07-05 10:13:36 +00001703- Issue #2663: add filtering capability to shutil.copytree().
1704

1708
1709- Issue #1746: Correct handling of zipfile archive comments (previously
1710 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001711 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001712
Vinay Sajip51e65192008-07-18 09:01:10 +00001713- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001714 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001715
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001716- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1717 handling is now the same as that of other special attributes like __name__).
1718
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001719- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1720 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002171- Issue #1631171: Re-implement the 'warnings' module in C (the
2172 original Python code has been kept as backup). This will allow for
2173 using the 'warning's machinery in such places as the parser where
2174 use of pure Python code is not possible. Both the ``showarning()``
2175 and ``formatwarning()`` gain an optional 'line' argument which is
2176 not called by default for backwards-compatibility reasons. Setting
2177 ``warnings.showwarning()`` to an implementation that lacks support
2178 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002241- Issue #2550: The approach used by client/server code for obtaining
2242 ports to listen on in network-oriented tests has been refined in an
2243 effort to facilitate running multiple instances of the entire
2244 regression test suite in parallel without issue.
2245 test_support.bind_port() has been fixed such that it will always
2246 return a unique port -- which wasn't always the case with the
2247 previous implementation, especially if socket options had been set
2248 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2249 new implementation of bind_port() will actually raise an exception
2250 if it is passed an AF_INET/SOCK_STREAM socket with either the
2251 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2252 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2253 the socket it's been passed. This currently only applies to
2254 Windows. This option prevents any other sockets from binding to the
2255 host/port we've bound to, thus removing the possibility of the
2256 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2257 when a second SOCK_STREAM socket binds and accepts to a host/port
2258 that's already been bound by another socket. The optional preferred
2259 port parameter to bind_port() has been removed. Under no
2260 circumstances should tests be hard coding ports!
2261
2262 test_support.find_unused_port() has also been introduced, which will
2263 pass a temporary socket object to bind_port() in order to obtain an
2264 unused port. The temporary socket object is then closed and
2265 deleted, and the port is returned. This method should only be used
2266 for obtaining an unused port in order to pass to an external program
2267 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2268 a parameter to a server-oriented class that doesn't give you direct
2269 access to the underlying socket used.
2270
2271 Finally, test_support.HOST has been introduced, which should be used
2272 for the host argument of any relevant socket calls (i.e. bind and
2273 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002274
2275 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002276 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002277 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2278 test_asynchat and test_socket_ssl.
2279
Georg Brandl3ee81df2008-05-17 18:14:43 +00002280 It is now possible for multiple instances of the regression test
2281 suite to run in parallel without issue.

2548-----------------
2549
Fred Drakea8ee94b2008-03-01 02:45:07 +00002550- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002551 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002552
Georg Brandlad61bc82008-02-23 15:11:18 +00002553- Issue #2067: file.__exit__() now calls subclasses' close() method.
2554
2555- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002556
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002557- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002558 issue 215555 for a discussion.
2559
Eric Smitha73fbe72008-02-23 03:09:44 +00002560- Added the future_builtins module, which contains hex() and oct().
2561 These are the PEP 3127 version of these functions, designed to be
2562 compatible with the hex() and oct() builtins from Python 3.0. They
2563 differ slightly in their output formats from the existing, unchanged
2564 Python 2.6 builtins. The expected usage of the future_builtins
2565 module is:
2566 from future_builtins import hex, oct
2567
Eric Smith7ef40bf2008-02-20 23:34:22 +00002568- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2569 exponents for exponents with absolute value < 100. Follows C99
2570 standard. This is a change on Windows, which would use 3 digits.
2571 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2572 so that any alterations it does to the resulting string will be
2573 available in stringlib/formatter.h (for float.__format__).
2574
Eric Smith5a3c1352008-02-19 13:21:56 +00002575- Implemented PEP 3101, Advanced String Formatting. This adds a new
2576 builtin format(); a format() method for str and unicode; a
2577 __format__() method to object, str, unicode, int, long, float, and
2578 datetime; the class string.Formatter; and the C API
2579 PyObject_Format().
2580
Georg Brandl3ee81df2008-05-17 18:14:43 +00002581- Fixed several potential crashes, all caused by specially crafted
2582 __del__ methods exploiting objects in temporarily inconsistent
2583 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002584
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002585- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002586 prevent a possible crash: an Abstract Base Class would try to access
2587 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002588
Georg Brandl3ee81df2008-05-17 18:14:43 +00002589- Fixed repr() and str() of complex numbers with infinity or nan as
2590 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002591
Georg Brandl3ee81df2008-05-17 18:14:43 +00002592- Clear all free lists during a gc.collect() of the highest generation
2593 in order to allow pymalloc to free more arenas. Python may give back
2594 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002595
Georg Brandl3ee81df2008-05-17 18:14:43 +00002596- Issue #2045: Fix an infinite recursion triggered when printing a
2597 subclass of collections.defaultdict, if its default_factory is set
2598 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002599
Christian Heimesf75dbef2008-02-08 00:11:31 +00002600- Fixed a minor memory leak in dictobject.c. The content of the free
2601 list was not freed on interpreter shutdown.
2602
Georg Brandl3ee81df2008-05-17 18:14:43 +00002603- Limit free list of method and builtin function objects to 256
2604 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002605
Georg Brandl3ee81df2008-05-17 18:14:43 +00002606- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2607 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002608 to compact the internal free lists of pre-allocted ints and floats.
2609
Georg Brandl3ee81df2008-05-17 18:14:43 +00002610- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2611 calls. Python expected the return type int but the fork familie
2612 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002613
Georg Brandl3ee81df2008-05-17 18:14:43 +00002614- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2615 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002616
Georg Brandl3ee81df2008-05-17 18:14:43 +00002617- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2618 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002619
Georg Brandl3ee81df2008-05-17 18:14:43 +00002620- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2621 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002622
Georg Brandl3ee81df2008-05-17 18:14:43 +00002623- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2624 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002625
Georg Brandl3ee81df2008-05-17 18:14:43 +00002626- Patch #1473257: generator objects gain a gi_code attribute. This is
2627 the same object as the func_code attribute of the function that
2628 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002629
Georg Brandl3ee81df2008-05-17 18:14:43 +00002630- Issue #1920: "while 0" statements were completely removed by the
2631 compiler, even in the presence of an "else" clause, which is
2632 supposed to be run when the condition is false. Now the compiler
2633 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002634
Guido van Rossumeead05f2008-01-24 18:21:02 +00002635- A few crashers fixed: weakref_in_del.py (issue #1377858);
2636 loosing_dict_ref.py (issue #1303614, test67.py);
2637 borrowed_ref_[34].py (not in tracker).
2638
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002639- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002640 suppressed while an extension is loaded by calling SetErrorMode in
2641 dynload_win.c. The error is still reported properly.
2642
Georg Brandl3ee81df2008-05-17 18:14:43 +00002643- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002644 several extension methods and modules do not work without unicode
2645 support.
2646
Georg Brandl26543b12008-01-21 18:36:51 +00002647- Issue #1882: when compiling code from a string, encoding cookies in the
2648 second line of code were not always recognized correctly.
2649
Georg Brandl14404b62008-01-19 19:27:05 +00002650- Issue #1679: "0x" was taken as a valid integer literal.
2651
Georg Brandl6caad7d2008-01-26 14:19:22 +00002652- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002653 added.
2654
Christian Heimesc94e2b52008-01-14 04:13:37 +00002655- sys.float_info / PyFloat_GetInfo: The floating point information
2656 object was converted from a dict to a specialized structseq object.
2657
Georg Brandl3ee81df2008-05-17 18:14:43 +00002658- Patch #1816: Added sys.flags structseq. It exposes the status of
2659 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002660
Georg Brandl3ee81df2008-05-17 18:14:43 +00002661- Objects/structseq.c: Implemented new structseq representation. The
2662 patch makes structseqs (e.g. the return value of os.stat) more
2663 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002664
Georg Brandl3ee81df2008-05-17 18:14:43 +00002665- Patch #1700288: added a type attribute cache that caches method
2666 accesses, resulting in speedups in heavily object-oriented code.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002673- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2674 envvar and sys.dont_write_bytecode attribute. All these can be set
2675 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002677- Improve some exception messages when Windows fails to load an
2678 extension module. Now we get for example '%1 is not a valid Win32
2679 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002680

Christian Heimes0a8143f2007-12-18 23:22:54 +00002686- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002687 and INF. float("nan"), float("inf") and float("-inf") now work on
2688 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002689
Georg Brandl3ee81df2008-05-17 18:14:43 +00002690- Compiler now generates simpler and faster code for dictionary
2691 literals. The oparg for BUILD_MAP now indicates an estimated
2692 dictionary size. There is a new opcode, STORE_MAP, for adding
2693 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002722- Patch #1739468: Directories and zipfiles containing a __main__.py
2723 file can now be directly executed by passing their name to the
2724 interpreter. The directory/zipfile is automatically inserted as the
2725 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002726
Georg Brandl3ee81df2008-05-17 18:14:43 +00002727- Issue #1265: Fix a problem with sys.settrace, if the tracing
2728 function uses a generator expression when at the same time the
2729 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002730
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002731- sets and frozensets now have an isdisjoint() method.

2734
Neal Norwitz44f326e2007-10-05 05:29:17 +00002735- Fix warnings found by the new version of the Coverity checker.
2736
Georg Brandl3ee81df2008-05-17 18:14:43 +00002737- The enumerate() builtin function is no longer bounded to sequences
2738 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2739 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002740
Georg Brandl3ee81df2008-05-17 18:14:43 +00002741- Issue #1686386: Tuple's tp_repr did not take into account the
2742 possibility of having a self-referential tuple, which is possible
2743 from C code. Nor did object's tp_str consider that a type's tp_str
2744 could do something that could lead to an inifinite recursion.
2745 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2746 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002747
Georg Brandl3ee81df2008-05-17 18:14:43 +00002748- Issue #1164: It was possible to trigger deadlock when using the
2749 'print' statement to write to a file since the GIL was not released
2750 as needed. Now PyObject_Print() does the right thing along with
2751 various tp_print implementations of the built-in types and those in
2752 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002753
Georg Brandl3ee81df2008-05-17 18:14:43 +00002754- Issue #1147: Exceptions were directly allowing string exceptions in
2755 their throw() method even though string exceptions no longer
2756 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002757
Georg Brandl3ee81df2008-05-17 18:14:43 +00002758- Issue #1096: Prevent a segfault from getting the repr of a very
2759 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002760
Brett Cannon1e534b52007-09-07 04:18:30 +00002761- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002762 PyObject_Call() never calling back out to Python code to trigger
2763 recursion depth updates/checks. Required the creation of a static
2764 RuntimeError instance in case normalizing an exception put the
2765 recursion check value past its limit. Fixes crashers
2766 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002767

Neal Norwitz0ac60192007-05-27 04:08:54 +00002781- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002782 __*__ attributes. (Some already existed, e.g., __doc__ and
2783 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002784
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002785- Add -3 option to the interpreter to warn about features that are
2786 deprecated and will be changed/removed in Python 3.0.
2787
Georg Brandl2134e752007-05-21 20:34:16 +00002788- Patch #1686487: you can now pass any mapping after '**' in function
2789 calls.
2790
Collin Winter62903052007-05-18 23:11:24 +00002791- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002792 "except E as target:". This is to provide forwards compatibility
2793 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002794
Brett Cannon229cee22007-05-05 01:34:02 +00002795- Deprecate BaseException.message as per PEP 352.
2796
Georg Brandl3ee81df2008-05-17 18:14:43 +00002797- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002798 inherited from a builtin base.
2799
Vinay Sajip8549ce32007-05-06 17:53:37 +00002800- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002801 setting a plain string, ie don't expand to single letter identifiers.
2802
Raymond Hettinger13936692007-04-11 18:40:58 +00002803- Request #1191699: Slices can now be pickled.
2804
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002805- Request #1193128: str.translate() now allows a None argument for
2806 translations that only remove characters without re-mapping the
2807 remaining characters.
2808
Georg Brandl5cb76c12007-03-21 09:00:39 +00002809- Patch #1682205: a TypeError while unpacking an iterable is no longer
2810 masked by a generic one with the message "unpack non-sequence".
2811
Neal Norwitzaa754b72007-03-21 06:39:48 +00002812- Remove unused file Python/fmod.c.
2813
Guido van Rossum143b5642007-03-23 04:58:42 +00002814- Bug #1683368: The object.__init__() and object.__new__() methods are
2815 now stricter in rejecting excess arguments. The only time when
2816 either allows excess arguments is when it is not overridden and the
2817 other one is. For backwards compatibility, when both are
2818 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002819 warning later). Also, type.__init__() insists on the same signature
2820 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002821
Georg Brandl3ee81df2008-05-17 18:14:43 +00002822- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2823 object to complex using its __complex__() method before falling back
2824 to the __float__() method. Therefore, the functions in the cmath
2825 module now can operate on objects that define a __complex__()
2826 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002827
Georg Brandl3ee81df2008-05-17 18:14:43 +00002828- Patch #1623563: allow __class__ assignment for classes with
2829 __slots__. The old and the new class are still required to have the
2830 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002831
Georg Brandl3ee81df2008-05-17 18:14:43 +00002832- Patch #1642547: Fix an error/crash when encountering syntax errors

2836 ``object.__reduce_ex__()`` is called with an object that is faking
2837 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002838
Georg Brandl3ee81df2008-05-17 18:14:43 +00002839- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002842- Patch #1444529: the builtin compile() now accepts keyword arguments.
2843
Georg Brandl7b9c5552007-03-12 14:30:05 +00002844- Bug #1678647: write a newline after printing an exception in any
2845 case, even when converting the value to a string failed.
2846
Georg Brandl871f1bc2007-03-12 13:17:36 +00002847- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002848 its argument, if it exists. If not, it will work like before. This
2849 allows customizing the output of dir() in the presence of a
2850 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002851
Collin Winter276887b2007-03-12 16:11:39 +00002852- Patch #922167: Python no longer segfaults when faced with infinitely
2853 self-recursive reload() calls (as reported by bug #742342).
2854
Georg Brandl3ee81df2008-05-17 18:14:43 +00002855- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002858- Patch #1491866: change the complex() constructor to allow
2859 parthensized forms. This means complex(repr(x)) now works instead of
2860 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002861
Georg Brandlaa2321b2007-03-07 00:40:28 +00002862- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002863 makes the filenames the warning module prints much more sensible
2864 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002865
Georg Brandl49aafc92007-03-07 00:34:46 +00002866- Variant of patch #697613: don't exit the interpreter on a SystemExit
2867 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002868 variable is given, but break into the interactive interpreter just
2869 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002877- Patch #1674228: when assigning a slice (old-style), check for the
2878 sq_ass_slice instead of the sq_slice slot.
2879
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- When printing an unraisable error, don't print exceptions. before
2881 the name. This duplicates the behavior whening normally printing
2882 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003415 AttributeError instead of an IOError when the server's response
3416 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003417

Georg Brandl3ee81df2008-05-17 18:14:43 +00003433- Patch #1530482: add pydoc.render_doc() which returns the

3448
Georg Brandl92a6bae2007-03-13 17:43:32 +00003449- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003450 are set for invalid interpolation sequences that would lead to
3451 errors on reading back those values.

3505
Georg Brandl3ee81df2008-05-17 18:14:43 +00003506- unittest now verifies more of its assumptions. In particular,
3507 TestCase and TestSuite subclasses (not instances) are no longer
3508 accepted in TestSuite.addTest(). This should cause no
3509 incompatibility since it never made sense with ordinary subclasses
3510 -- the failure just occurred later, with a more cumbersome
3511 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003798 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00003900 time so that opening a database previously created with the DB_DUP
3901 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3902 opens. Specifically: dictionary assignment to a DB object will
3903 replace all values for a given key when the database allows
3904 duplicate values. DB users should use DB.put(k, v) when they want
3905 to store duplicates; not DB[k] = v.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004184- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185 periodic threadstate and signal checking in tight loops. By
4186 default, this option is turned-off. It should only be enabled in

4238-----
4239
Georg Brandl3ee81df2008-05-17 18:14:43 +00004240- Unified naming convention for free lists and their limits. All free
4241 lists in Object/ are named ``free_list``, the counter ``numfree``

4243 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004244
Georg Brandl3ee81df2008-05-17 18:14:43 +00004245- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4246 to ``PyTuple_SetItem``, it can be used to populate a brand new
4247 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004248

4259
Georg Brandl3ee81df2008-05-17 18:14:43 +00004260- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4261 of w# format code incorrectly truncated the length to an int, even
4262 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4263 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004264
Georg Brandl3ee81df2008-05-17 18:14:43 +00004265- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4285
4286- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4287 outside of pystate.c and should not be necessary.
4288
Georg Brandl3ee81df2008-05-17 18:14:43 +00004289- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4290 absolute imports. In earlier versions they might have used relative
4291 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004292
Georg Brandl3ee81df2008-05-17 18:14:43 +00004293- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4294 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004295
Georg Brandl3ee81df2008-05-17 18:14:43 +00004296- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004321- Removed the macfs module. It had been deprecated since Python 2.5.
4322 This lead to the deprecation of macostools.touched() as it relied
