933What's New in Python 2.6.1
934==========================
935
936*Release date: 04-Dec-2008*
937
938Core and Builtins
939-----------------
940
941- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
942 interpreter to abort ("Fatal Python error: Could not reset the stack!")
943 instead of throwing a MemoryError.
944
945- Issue #4367: Python would segfault during compiling when the unicodedata
946 module couldn't be imported and \N escapes were present.
947
948- Issue #4348: Some bytearray methods returned that didn't cause any change to
949 the bytearray, returned the same bytearray instead of a copy.
950
951- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
952
953- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
954
955- Issue #4048: The parser module now correctly validates relative imports.
956
957- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
958 exec statement.
959
960- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
961 method does not return iterators for the 4th and 5th items.
962
963- Issue #4209: Enabling unicode_literals and the print_function in the same
964 __future__ import didn't work.
965
966- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
967 returned a path longer than MAX_PATH. (But It's doubtful this code path is
968 really executed because I cannot move to such directory on win2k)
969
970- Issue #4069: When set.remove(element) is used with a set element, the element
971 is temporarily replaced with an equivalent frozenset. But the eventual
972 KeyError would always report the empty frozenset([]) as the missing key. Now
973 it correctly refers to the initial element.
974
975- Fixed C99 style comments in several files. Python is now C89 compatible
976 again.

1124
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001125- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1126 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1127 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1128 ``printf`` function, whereas PyString_FromFormat has an independent
1129 implementation and uses "%zd" on all platforms for size_t values.
1130 This makes a difference on win64, where ``printf`` needs "%Id" to display
1131 64bit values.

1137 object; previously an int would be returned for small values. the __long__
1138 method is allowed to return either an int or a long, but the behaviour of
1139 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001141- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001148 was correctly parsed but parsing of subsequent arguments failed.
1149
Vinay Sajip35e3b032008-09-01 14:33:59 +00001150- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001151 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1152 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1153 when given a tuple of classes as second argument, were looking up
1154 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1155 type object.

1298
Guido van Rossumf8402962008-08-20 15:01:50 +00001299- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1300 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1301 extensions do not automatically benefit from the class attribute
1302 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1303 to their tp_flags field if they care. This is a backwards
1304 compatibility feature; in 3.0, all types will use the cache by
1305 default.

1308 keyword=23)`` is now valid syntax.)
1309
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001310- ctypes function pointers that are COM methods have a boolean True
1311 value again.
1312
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001313- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1314 by denying s# to parse objects that have a releasebuffer procedure,
1315 and introducing s*.
1316
Georg Brandl1e13ea92008-08-11 09:07:59 +00001317- Issue #3537: Fix an assertion failure when an empty but presized dict
1318 object was stored in the freelist.
1319
Mark Dickinsonb6467572008-08-04 21:30:09 +00001320- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1321 ValueError consistently across platforms.
1322
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001323- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1324 (64bit Unix, for example), unichr() would truncate its argument and return
1325 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1326
Neal Norwitze7d8be82008-07-31 17:17:14 +00001327- Apply security patches from Apple.
1328
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001329- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1330 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1331
Antoine Pitrou92f82162008-07-25 22:22:08 +00001332- Issue #1819: function calls with several named parameters are now on
1333 average 35% faster (as measured by pybench).
1334
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001335- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1336 the python debugger steps into a class statement: the free variables (local
1337 variables defined in an outer scope) would be deleted from the outer scope.
1338
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001339- Issue #2620: Overflow checking when allocating or reallocating memory
1340 was not always being done properly in some python types and extension
1341 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1342 all been updated to perform better checks and places in the code that
1343 would previously leak memory on the error path when such an allocation
1344 failed have been fixed.

1350
Benjamin Petersone977ad42008-08-20 01:42:01 +00001351- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1352 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1353
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001354- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1355 version reported by these tools does not necessarily follow the python
1356 version numbering scheme, so the module is less strict when parsing it.
1357
Nick Coghlanf70385a2008-08-18 12:42:46 +00001358- Issue #2235: Added Py3k warnings for types which will become unhashable
1359 under the stricter __hash__ inheritance rules in 3.0. Several types
1360 which did not meet the rules for hash invariants and were already
1361 unhashable in 3.0 have now been explicitly flagged as unhashable in
1362 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1363 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1364
Brett Cannon88f801d2008-08-18 00:46:22 +00001365- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1366 imported into the module but exposed as part of the module's API.
1367
Brett Cannon7b96f072008-08-18 00:41:11 +00001368- Remove an unneeded import of abc.ABCMeta from 'inspect'.

1373
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001374- Issue #3575: Incremental decoder's decode function now takes bytearray
1375 by using 's*' instead of 't#'.
1376
Jesus Cea585ad8a2009-07-02 15:37:21 +00001377- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001378 fails unicode conversion on 2nd parameter. (windows only)
1379
Facundo Batista94f243a2008-08-17 03:38:39 +00001380- Issue 2464. urllib2 now supports a malformation in the URL received
1381 in a redirect.

Brett Cannonabe423e2008-08-16 21:47:07 +00001385
Facundo Batistaeb90b782008-08-16 14:44:07 +00001386- Issue #2776: fixed small issue when handling an URL with double slash
1387 after a 302 response in the case of not going through a proxy.
1388
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001389- Issue #2676: in the email package, content-type parsing was hanging on
1390 pathological input because of quadratic or exponential behaviour of a
1391 regular expression.
1392
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001393- Issue #3476: binary buffered reading through the new "io" library is now
1394 thread-safe.
1395
Brett Cannonbf3157b2008-08-14 05:00:03 +00001396- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1397 since mimetools itself is deprecated. Because modules are cached, all
1398 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1399
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001400- Issue #3134: shutil referenced undefined WindowsError symbol.
1401
Robert Schuppenies14646332008-08-10 11:01:53 +00001402- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1403 menu entries were not deleted.
1404
Brett Cannon83e81842008-08-09 23:30:55 +00001405- Copied the implementation of reduce() to _functools.reduce() to have a
1406 version that did not raise a DeprecationWarning under -3.
1407
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001408- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1409 a MemoryError rather than silently stop the iteration.
1410
Guido van Rossum59ce9012008-08-09 14:55:34 +00001411- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1412 to _sre.compile() will now be rejected. This should not affect anybody
1413 since the re.compile() function never generates invalid re-bytecode.
1414
Skip Montanaroa032bf42008-08-08 22:52:51 +00001415- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1416 upon first access it can be automatically initialized from the csv file if
1417 it wasn't initialized during instantiation.
1418
Brett Cannon3aa2a492008-08-06 22:28:09 +00001419- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1420 the reload() built-in has been removed.
1421
Brett Cannon7e30b672008-08-04 21:52:25 +00001422- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001423 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1431 raised an AttributeError.
1432
Benjamin Peterson01a24322008-07-28 23:35:27 +00001433- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001434 asking for a specific length. This problem only affected files opened
1435 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001436

1459
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001460- Issue #3394: zipfile.writestr sets external attributes when passed a
1461 file name rather than a ZipInfo instance, so files are extracted with
1462 mode 0600 rather than 000 under Unix.
1463
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001464- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1465 argument in python 2.5, this broke code that subclassed Popen to include its
1466 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1474-------------
1475
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001476- Issue #2235: the C API function PyObject_HashNotImplemented and its
1477 interaction with the tp_hash slot (added in 2.6b2) are now documented
1478
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001479- Issue #643841: The language reference now provides more detailed
1480 coverage of the lookup process for special methods. The disclaimers
1481 regarding lack of coverage of new-style classes have also been
1482 removed, since the coverage is now fairly reasonable.

1487
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001488*Release date: 17-Jul-2008*
1489
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001490Core and Builtins
1491-----------------
1492
Georg Brandl3e483f62008-07-16 22:57:41 +00001493- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1494 its methods now allow for items objects that can be converted to
1495 an integer using operator.index().
1496
Mark Dickinson64b7e502008-07-16 09:40:03 +00001497- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1498 produced a ValueError instead of giving the correct float.
1499
Eric Smitha5fa5a22008-07-16 00:11:49 +00001500- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1501 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1502
Mark Dickinson7103aa42008-07-15 19:08:33 +00001503- Issue #3008: the float type has a new instance method 'float.hex'
1504 and a new class method 'float.fromhex' to convert floating-point
1505 numbers to and from hexadecimal strings, respectively.
1506
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001507- Issue #2235: __hash__ is once again inherited by default. To allow
1508 collections.Hashable to remain meaningful in the presence of the
1509 default hash implementation (object.__hash__), it is now possible
1510 to explicit block inheritance of hash by setting __hash__=None at
1511 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1512 level.
1513
Nick Coghlanb028f502008-07-13 14:52:36 +00001514- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1515 the parent module cannot be found while performing an absolute import.
1516 This means that an incorrectly defined __package__ attribute will
1517 now only prevent relative imports in that module rather than causing
1518 all imports from that module to fail.
1519
Nick Coghlan14ff9942008-07-08 14:21:42 +00001520- Issue #2517: Allow unicode messages in Exceptions again by correctly
1521 bypassing the instance dictionary when looking up __unicode__ on
1522 new-style classes.
1523
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001524- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1525 set to a custom object whose write() method happens to install
1526 another file in sys.stdout.
1527
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001528- Issue #3088: Corrected a race condition in classes derived from
1529 threading.local: the first member set by a thread could be saved in
1530 another thread's dictionary.
1531
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001532- Issue #3004: Minor change to slice.indices(): the start and stop
1533 arguments are now treated identically, making the behaviour easier
1534 to describe and understand. For example, slice(None, -10,
1535 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1536 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1537 10, -1).
1538
Georg Brandl278fc502008-07-19 12:46:12 +00001539- Issue #3219: Calling a function with repeated keyword arguments,
1540 f(a=2, a=23), would not cause a syntax error. This was a regression
1541 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001542
Georg Brandl278fc502008-07-19 12:46:12 +00001543- Issue #2862: Make int and float freelist management consistent with
1544 other freelists. Changes their CompactFreeList apis into
1545 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001546

1548-------
1549
Thomas Heller57adf222008-08-14 19:10:48 +00001550- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1551 api functions without holding the GIL, which could lead to a fatal
1552 error when they failed.
1553
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001554- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1563 ForkingPickler.register() to resolve conflict with ctypes.
1564
Vinay Sajip51e65192008-07-18 09:01:10 +00001565- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001566
Thomas Heller880f5292008-07-15 19:39:38 +00001567- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1568 a valid dlerror() message.
1569
Thomas Heller2bad6572008-07-15 17:19:50 +00001570- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1571 incomplete structure was created.
1572
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001573- Issue #3339: dummy_thread.acquire() should not return None.
1574
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001575- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1576
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001577- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001578
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001579- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1580 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001581 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001582 content-length. The problem had been corrected in the 2.4 branch, but never
1583 merged into trunk.
1584
Georg Brandle78fbcc2008-07-05 10:13:36 +00001585- Issue #2663: add filtering capability to shutil.copytree().

1990 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001991 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001992
1993 This is controlled by the configure argument ``--with-universal-archs``:
1994
1995 - ``--with-universal-archs=all``: install 4-way universal
1996
1997 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1998
1999 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2000
2001 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002053- Issue #1631171: Re-implement the 'warnings' module in C (the
2054 original Python code has been kept as backup). This will allow for
2055 using the 'warning's machinery in such places as the parser where
2056 use of pure Python code is not possible. Both the ``showarning()``
2057 and ``formatwarning()`` gain an optional 'line' argument which is
2058 not called by default for backwards-compatibility reasons. Setting
2059 ``warnings.showwarning()`` to an implementation that lacks support
2060 for the ``line`` argument will raise a DeprecationWarning.

2084
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002085- The getpass module has been improved on Unix. It now uses /dev/tty
2086 by default and uses stderr instead of stdout. A GetPassWarning is
2087 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002088

Georg Brandl3ee81df2008-05-17 18:14:43 +00002102- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002103 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002123- Issue #2550: The approach used by client/server code for obtaining
2124 ports to listen on in network-oriented tests has been refined in an
2125 effort to facilitate running multiple instances of the entire
2126 regression test suite in parallel without issue.
2127 test_support.bind_port() has been fixed such that it will always
2128 return a unique port -- which wasn't always the case with the
2129 previous implementation, especially if socket options had been set
2130 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2131 new implementation of bind_port() will actually raise an exception
2132 if it is passed an AF_INET/SOCK_STREAM socket with either the
2133 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2134 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2135 the socket it's been passed. This currently only applies to
2136 Windows. This option prevents any other sockets from binding to the
2137 host/port we've bound to, thus removing the possibility of the
2138 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2139 when a second SOCK_STREAM socket binds and accepts to a host/port
2140 that's already been bound by another socket. The optional preferred
2141 port parameter to bind_port() has been removed. Under no
2142 circumstances should tests be hard coding ports!
2143
2144 test_support.find_unused_port() has also been introduced, which will
2145 pass a temporary socket object to bind_port() in order to obtain an
2146 unused port. The temporary socket object is then closed and
2147 deleted, and the port is returned. This method should only be used
2148 for obtaining an unused port in order to pass to an external program
2149 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2150 a parameter to a server-oriented class that doesn't give you direct
2151 access to the underlying socket used.
2152
2153 Finally, test_support.HOST has been introduced, which should be used
2154 for the host argument of any relevant socket calls (i.e. bind and
2155 connect).

2429Core and builtins
2430-----------------
2431
Fred Drakea8ee94b2008-03-01 02:45:07 +00002432- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002433 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002434
Georg Brandlad61bc82008-02-23 15:11:18 +00002435- Issue #2067: file.__exit__() now calls subclasses' close() method.
2436
2437- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002438
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002439- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002440 issue 215555 for a discussion.
2441
Eric Smitha73fbe72008-02-23 03:09:44 +00002442- Added the future_builtins module, which contains hex() and oct().
2443 These are the PEP 3127 version of these functions, designed to be
2444 compatible with the hex() and oct() builtins from Python 3.0. They
2445 differ slightly in their output formats from the existing, unchanged
2446 Python 2.6 builtins. The expected usage of the future_builtins
2447 module is:
2448 from future_builtins import hex, oct
2449
Eric Smith7ef40bf2008-02-20 23:34:22 +00002450- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2451 exponents for exponents with absolute value < 100. Follows C99
2452 standard. This is a change on Windows, which would use 3 digits.
2453 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2454 so that any alterations it does to the resulting string will be
2455 available in stringlib/formatter.h (for float.__format__).
2456
Eric Smith5a3c1352008-02-19 13:21:56 +00002457- Implemented PEP 3101, Advanced String Formatting. This adds a new
2458 builtin format(); a format() method for str and unicode; a
2459 __format__() method to object, str, unicode, int, long, float, and
2460 datetime; the class string.Formatter; and the C API
2461 PyObject_Format().
2462
Georg Brandl3ee81df2008-05-17 18:14:43 +00002463- Fixed several potential crashes, all caused by specially crafted
2464 __del__ methods exploiting objects in temporarily inconsistent
2465 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002466
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002467- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002468 prevent a possible crash: an Abstract Base Class would try to access
2469 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002470
Georg Brandl3ee81df2008-05-17 18:14:43 +00002471- Fixed repr() and str() of complex numbers with infinity or nan as
2472 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002473
Georg Brandl3ee81df2008-05-17 18:14:43 +00002474- Clear all free lists during a gc.collect() of the highest generation
2475 in order to allow pymalloc to free more arenas. Python may give back
2476 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002477
Georg Brandl3ee81df2008-05-17 18:14:43 +00002478- Issue #2045: Fix an infinite recursion triggered when printing a
2479 subclass of collections.defaultdict, if its default_factory is set
2480 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002481
Christian Heimesf75dbef2008-02-08 00:11:31 +00002482- Fixed a minor memory leak in dictobject.c. The content of the free
2483 list was not freed on interpreter shutdown.
2484
Georg Brandl3ee81df2008-05-17 18:14:43 +00002485- Limit free list of method and builtin function objects to 256
2486 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002487
Georg Brandl3ee81df2008-05-17 18:14:43 +00002488- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2489 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002490 to compact the internal free lists of pre-allocted ints and floats.
2491
Georg Brandl3ee81df2008-05-17 18:14:43 +00002492- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2493 calls. Python expected the return type int but the fork familie
2494 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002495
Georg Brandl3ee81df2008-05-17 18:14:43 +00002496- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2497 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002498
Georg Brandl3ee81df2008-05-17 18:14:43 +00002499- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2500 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002501
Georg Brandl3ee81df2008-05-17 18:14:43 +00002502- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2503 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002504
Georg Brandl3ee81df2008-05-17 18:14:43 +00002505- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2506 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002507
Georg Brandl3ee81df2008-05-17 18:14:43 +00002508- Patch #1473257: generator objects gain a gi_code attribute. This is
2509 the same object as the func_code attribute of the function that
2510 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002511
Georg Brandl3ee81df2008-05-17 18:14:43 +00002512- Issue #1920: "while 0" statements were completely removed by the
2513 compiler, even in the presence of an "else" clause, which is
2514 supposed to be run when the condition is false. Now the compiler
2515 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002516
Guido van Rossumeead05f2008-01-24 18:21:02 +00002517- A few crashers fixed: weakref_in_del.py (issue #1377858);
2518 loosing_dict_ref.py (issue #1303614, test67.py);
2519 borrowed_ref_[34].py (not in tracker).
2520
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002521- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002522 suppressed while an extension is loaded by calling SetErrorMode in
2523 dynload_win.c. The error is still reported properly.
2524
Georg Brandl3ee81df2008-05-17 18:14:43 +00002525- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002526 several extension methods and modules do not work without unicode
2527 support.
2528
Georg Brandl26543b12008-01-21 18:36:51 +00002529- Issue #1882: when compiling code from a string, encoding cookies in the
2530 second line of code were not always recognized correctly.
2531
Georg Brandl14404b62008-01-19 19:27:05 +00002532- Issue #1679: "0x" was taken as a valid integer literal.
2533
Georg Brandl6caad7d2008-01-26 14:19:22 +00002534- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002535 added.
2536
Christian Heimesc94e2b52008-01-14 04:13:37 +00002537- sys.float_info / PyFloat_GetInfo: The floating point information
2538 object was converted from a dict to a specialized structseq object.
2539
Georg Brandl3ee81df2008-05-17 18:14:43 +00002540- Patch #1816: Added sys.flags structseq. It exposes the status of
2541 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002542
Georg Brandl3ee81df2008-05-17 18:14:43 +00002543- Objects/structseq.c: Implemented new structseq representation. The
2544 patch makes structseqs (e.g. the return value of os.stat) more
2545 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002546
Georg Brandl3ee81df2008-05-17 18:14:43 +00002547- Patch #1700288: added a type attribute cache that caches method
2548 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002549
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002550- Bug #1776: __import__() no longer accepts filenames on any platform.
2551 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002552
Georg Brandlaed6c662008-01-07 17:25:53 +00002553- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2554
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2556 envvar and sys.dont_write_bytecode attribute. All these can be set
2557 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002558
Georg Brandl3ee81df2008-05-17 18:14:43 +00002559- Improve some exception messages when Windows fails to load an
2560 extension module. Now we get for example '%1 is not a valid Win32
2561 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002562
Georg Brandl3ee81df2008-05-17 18:14:43 +00002563- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002565- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2566 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002567
Christian Heimes0a8143f2007-12-18 23:22:54 +00002568- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002569 and INF. float("nan"), float("inf") and float("-inf") now work on
2570 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002571
Georg Brandl3ee81df2008-05-17 18:14:43 +00002572- Compiler now generates simpler and faster code for dictionary
2573 literals. The oparg for BUILD_MAP now indicates an estimated
2574 dictionary size. There is a new opcode, STORE_MAP, for adding
2575 entries to the dictionary.

2593 running, and if the deallocation of its frames somehow calls the
2594 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002595

2605 file can now be directly executed by passing their name to the
2606 interpreter. The directory/zipfile is automatically inserted as the
2607 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002608
Georg Brandl3ee81df2008-05-17 18:14:43 +00002609- Issue #1265: Fix a problem with sys.settrace, if the tracing
2610 function uses a generator expression when at the same time the
2611 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002612
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002613- sets and frozensets now have an isdisjoint() method.
2614
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002615- optimize the performance of builtin.sum().
2616
Neal Norwitz44f326e2007-10-05 05:29:17 +00002617- Fix warnings found by the new version of the Coverity checker.
2618
Georg Brandl3ee81df2008-05-17 18:14:43 +00002619- The enumerate() builtin function is no longer bounded to sequences
2620 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2621 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002622
Georg Brandl3ee81df2008-05-17 18:14:43 +00002623- Issue #1686386: Tuple's tp_repr did not take into account the
2624 possibility of having a self-referential tuple, which is possible
2625 from C code. Nor did object's tp_str consider that a type's tp_str
2626 could do something that could lead to an inifinite recursion.
2627 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2628 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002629
Georg Brandl3ee81df2008-05-17 18:14:43 +00002630- Issue #1164: It was possible to trigger deadlock when using the
2631 'print' statement to write to a file since the GIL was not released
2632 as needed. Now PyObject_Print() does the right thing along with
2633 various tp_print implementations of the built-in types and those in
2634 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002636- Issue #1147: Exceptions were directly allowing string exceptions in
2637 their throw() method even though string exceptions no longer
2638 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002639
Georg Brandl3ee81df2008-05-17 18:14:43 +00002640- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002643- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002644 PyObject_Call() never calling back out to Python code to trigger
2645 recursion depth updates/checks. Required the creation of a static
2646 RuntimeError instance in case normalizing an exception put the
2647 recursion check value past its limit. Fixes crashers
2648 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002663- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002664 __*__ attributes. (Some already existed, e.g., __doc__ and
2665 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002666
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002667- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00002674 "except E as target:". This is to provide forwards compatibility
2675 with Python 3.0.

2695
Guido van Rossum143b5642007-03-23 04:58:42 +00002696- Bug #1683368: The object.__init__() and object.__new__() methods are
2697 now stricter in rejecting excess arguments. The only time when
2698 either allows excess arguments is when it is not overridden and the
2699 other one is. For backwards compatibility, when both are
2700 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002701 warning later). Also, type.__init__() insists on the same signature
2702 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002703
Georg Brandl3ee81df2008-05-17 18:14:43 +00002704- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2705 object to complex using its __complex__() method before falling back
2706 to the __float__() method. Therefore, the functions in the cmath
2707 module now can operate on objects that define a __complex__()
2708 method.

2725
Georg Brandl7b9c5552007-03-12 14:30:05 +00002726- Bug #1678647: write a newline after printing an exception in any
2727 case, even when converting the value to a string failed.
2728
Georg Brandl871f1bc2007-03-12 13:17:36 +00002729- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002730 its argument, if it exists. If not, it will work like before. This
2731 allows customizing the output of dir() in the presence of a
2732 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00002734- Patch #922167: Python no longer segfaults when faced with infinitely
2735 self-recursive reload() calls (as reported by bug #742342).

2742 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002743
Georg Brandlaa2321b2007-03-07 00:40:28 +00002744- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002745 makes the filenames the warning module prints much more sensible
2746 when a PYTHONSTARTUP file is used.

2760 sq_ass_slice instead of the sq_slice slot.
2761
Georg Brandl3ee81df2008-05-17 18:14:43 +00002762- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003388- unittest now verifies more of its assumptions. In particular,
3389 TestCase and TestSuite subclasses (not instances) are no longer
3390 accepted in TestSuite.addTest(). This should cause no
3391 incompatibility since it never made sense with ordinary subclasses
3392 -- the failure just occurred later, with a more cumbersome
3393 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003674- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3675 with RFC 3207 and forgets any knowledge obtained from the server not
3676 obtained from the TLS negotiation itself. Patch contributed by Bill
3677 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003678
Georg Brandl3ee81df2008-05-17 18:14:43 +00003679- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003680 that the SMTP.starttls() caller no longer needs to call ehlo()
3681 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003682 does not claim to support starttls. Adds the
3683 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3764 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3765 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003782 time so that opening a database previously created with the DB_DUP
3783 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3784 opens. Specifically: dictionary assignment to a DB object will
3785 replace all values for a given key when the database allows
3786 duplicate values. DB users should use DB.put(k, v) when they want
3787 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003788

3794 characters with ASCII value less than 32. Also, it correctly quotes
3795 dots only if they occur on a single line, as opposed to the previous
3796 behavior of quoting dots if they are the second character of any
3797 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003798

Georg Brandl3ee81df2008-05-17 18:14:43 +00004127- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4128 to ``PyTuple_SetItem``, it can be used to populate a brand new
4129 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00004131- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004133- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4134 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4135 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004136
4137- Patch #1720595: add T_BOOL to the range of structmember types.
4138
4139- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4140 ``PyFloat_GetInfo()`` to the float API.
4141
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4143 of w# format code incorrectly truncated the length to an int, even
4144 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4145 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004146
Georg Brandl3ee81df2008-05-17 18:14:43 +00004147- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4148 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004150- PEP 3123: Provide forward compatibility with Python 3.0, while
4151 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4152 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004153
Georg Brandl3ee81df2008-05-17 18:14:43 +00004154- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4155 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004156
4157- Patch #1733960: Allow T_LONGLONG to accept ints.
4158
4159- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4160
Christian Heimes000a0742008-01-03 22:16:32 +00004161- Added a new API function ``PyImport_ImportModuleNoBlock``.
4162
Georg Brandl6caad7d2008-01-26 14:19:22 +00004163- Bug #1637022: Prefix AST symbols with _Py_.
4164
4165- Fix some leftovers from the conversion from int to Py_ssize_t
4166 (relevant to strings and sequences of more than 2**31 items).
4167
4168- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4169 outside of pystate.c and should not be necessary.
4170
Georg Brandl3ee81df2008-05-17 18:14:43 +00004171- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4172 absolute imports. In earlier versions they might have used relative
4173 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004174
Georg Brandl3ee81df2008-05-17 18:14:43 +00004175- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4176 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004177
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004185- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4186 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4187 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4188 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00004201- buildtools now raises a DeprecationWarning.
4202
Georg Brandl3ee81df2008-05-17 18:14:43 +00004203- Removed the macfs module. It had been deprecated since Python 2.5.
4204 This lead to the deprecation of macostools.touched() as it relied
4205 solely on macfs and was a no-op under OS X.
