82 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Benjamin Peterson00b90512010-01-25 03:35:04 +000084- Issue #7773: Fix an UnboundLocalError in platform.linux_distribution() when

Tarek Ziadé06426fc2010-01-11 22:54:57 +0000105- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

115
Antoine Pitrou0b074572010-01-08 19:21:34 +0000116- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
117 renaming of `cPickle` to `pickle`. The warning was annoying since there's
118 no alternative to cPickle if you care about performance. Patch by Florent
119 Xicluna.
120
Antoine Pitrou8dba7272010-01-07 18:04:12 +0000121- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

Antoine Pitroueaaf66c2009-11-13 22:33:27 +0000157- Issue #7318: multiprocessing now uses a timeout when it fails to establish
158 a connection with another process, rather than looping endlessly. The

176
Gregory P. Smith6da85f92009-11-01 18:31:13 +0000177- Issue #7246 & Issue #7208: getpass now properly flushes input before
178 reading from stdin so that existing input does not confuse it and
179 lead to incorrect entry or an IOError. It also properly flushes it
180 afterwards to avoid the terminal echoing the input afterwards on
181 OSes such as Solaris.

187 sure that they accept an int or long as the second argument. Also
188 fix buggy handling of large arguments (those with coefficient longer
189 than the current precision) in shift and rotate.
190
R. David Murray7034db32009-10-27 23:39:06 +0000191- Issue #7082: When falling back to the MIME 'name' parameter, the
192 correct place to look for it is the Content-Type header.
193
Mark Dickinson20a7cfc2009-10-27 18:27:53 +0000194- Issue #7099: Decimal.is_normal now returns True for numbers with exponent
195 larger than emax.

201 is too large to fit in the current precision.
202
Matthias Kloseb9ba2bb2010-01-16 10:31:22 +0000203- Issue #1488943: difflib.Differ() doesn't always add hints for tab characters

715 Patch by Ziga Seilnacht and Jean-Paul Calderone.

Vinay Sajip6badbe92009-01-20 22:49:13 +0000752- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000753 method on file objects with closefd=False. The file descriptor is still
754 kept open but the file object behaves like a closed file. The ``FileIO``
755 object also got a new readonly attribute ``closefd``.
756
Georg Brandlfa71a902008-12-05 09:08:28 +0000757- Issue #3689: The list reversed iterator now supports __length_hint__

1128What's New in Python 2.6.1
1129==========================
1130
1131*Release date: 04-Dec-2008*
1132
1133Core and Builtins
1134-----------------
1135
1136- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1137 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1138 instead of throwing a MemoryError.
1139
1140- Issue #4367: Python would segfault during compiling when the unicodedata
1141 module couldn't be imported and \N escapes were present.
1142
1143- Issue #4348: Some bytearray methods returned that didn't cause any change to
1144 the bytearray, returned the same bytearray instead of a copy.
1145
1146- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1147
1148- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1149
1150- Issue #4048: The parser module now correctly validates relative imports.
1151
1152- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1153 exec statement.
1154
1155- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1156 method does not return iterators for the 4th and 5th items.
1157
1158- Issue #4209: Enabling unicode_literals and the print_function in the same
1159 __future__ import didn't work.
1160
1161- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1162 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1163 really executed because I cannot move to such directory on win2k)
1164
1165- Issue #4069: When set.remove(element) is used with a set element, the element
1166 is temporarily replaced with an equivalent frozenset. But the eventual
1167 KeyError would always report the empty frozenset([]) as the missing key. Now
1168 it correctly refers to the initial element.
1169
1170- Fixed C99 style comments in several files. Python is now C89 compatible
1171 again.

1316-----------------
1317
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001318- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1319
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001320- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1321 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1322 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1323 ``printf`` function, whereas PyString_FromFormat has an independent
1324 implementation and uses "%zd" on all platforms for size_t values.
1325 This makes a difference on win64, where ``printf`` needs "%Id" to display
1326 64bit values.
1327
Benjamin Peterson97179b02008-09-09 20:55:01 +00001328- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1329 error.
1330
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001331- Issue #3777: long() applied to a float object now always return a long
1332 object; previously an int would be returned for small values. the __long__
1333 method is allowed to return either an int or a long, but the behaviour of
1334 float objects should not change to respect backward compatibility.
1335
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001336- Issue #3751: str.rpartition would perform a left-partition when called with
1337 a unicode argument.
1338
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001339- Issue #3683: Fix compilation when --without-threads is given.
1340
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001341- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001342 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001343 was correctly parsed but parsing of subsequent arguments failed.
1344
Vinay Sajip35e3b032008-09-01 14:33:59 +00001345- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001346 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1347 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1348 when given a tuple of classes as second argument, were looking up
1349 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1350 type object.
1351
Neal Norwitz18aa3882008-08-24 05:04:52 +00001352- Fix crashes on memory allocation failure found with failmalloc.
1353
1354- Fix memory leaks found with valgrind and update suppressions file.
1355
1356- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1357
1358- Fix problem using wrong name in decimal module reported by pychecker.
1359
Christian Heimes7d4c3172008-08-22 19:47:25 +00001360- Silenced another compiler warning about a used but not defined
1361 function 'stringlib_contains_obj'.

1364 ``__delslice__``.
1365
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001366- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1367 library targets in the Makefile.
1368
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001369- Issue #1204: The configure script now tests for additional libraries
1370 that may be required when linking against readline. This fixes issues
1371 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1390 with statements, or when the methods are invoked in the wrong order.
1391

Nick Coghland2e09382008-09-11 12:11:06 +00001394- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001395 return a list or None rather than a custom object.

1421 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1422 for catch_warnings() also led to an improvement in the raising of a
1423 DeprecationWarning related to warnings.warn_explicit().
1424
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001425- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001486What's New in Python 2.6 beta 3?
1487================================
1488
Barry Warsaw07a4a382008-08-21 01:15:08 +00001489*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001490
1491Core and Builtins
1492-----------------
1493
Guido van Rossumf8402962008-08-20 15:01:50 +00001494- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1495 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1496 extensions do not automatically benefit from the class attribute
1497 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1498 to their tp_flags field if they care. This is a backwards
1499 compatibility feature; in 3.0, all types will use the cache by
1500 default.
1501
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001502- Keyword arguments can now follow starred arguments. (``f(a, *args,
1503 keyword=23)`` is now valid syntax.)
1504
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001505- ctypes function pointers that are COM methods have a boolean True
1506 value again.
1507
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001508- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1509 by denying s# to parse objects that have a releasebuffer procedure,
1510 and introducing s*.
1511
Georg Brandl1e13ea92008-08-11 09:07:59 +00001512- Issue #3537: Fix an assertion failure when an empty but presized dict
1513 object was stored in the freelist.
1514
Mark Dickinsonb6467572008-08-04 21:30:09 +00001515- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1516 ValueError consistently across platforms.
1517
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001518- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1519 (64bit Unix, for example), unichr() would truncate its argument and return
1520 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1521
Neal Norwitze7d8be82008-07-31 17:17:14 +00001522- Apply security patches from Apple.
1523
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001524- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1525 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1526
Antoine Pitrou92f82162008-07-25 22:22:08 +00001527- Issue #1819: function calls with several named parameters are now on
1528 average 35% faster (as measured by pybench).
1529
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001530- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1531 the python debugger steps into a class statement: the free variables (local
1532 variables defined in an outer scope) would be deleted from the outer scope.
1533
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001534- Issue #2620: Overflow checking when allocating or reallocating memory
1535 was not always being done properly in some python types and extension
1536 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1537 all been updated to perform better checks and places in the code that
1538 would previously leak memory on the error path when such an allocation
1539 failed have been fixed.

1545
Benjamin Petersone977ad42008-08-20 01:42:01 +00001546- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1547 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1548
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001549- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1550 version reported by these tools does not necessarily follow the python
1551 version numbering scheme, so the module is less strict when parsing it.
1552
Nick Coghlanf70385a2008-08-18 12:42:46 +00001553- Issue #2235: Added Py3k warnings for types which will become unhashable
1554 under the stricter __hash__ inheritance rules in 3.0. Several types
1555 which did not meet the rules for hash invariants and were already
1556 unhashable in 3.0 have now been explicitly flagged as unhashable in
1557 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1558 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1559
Brett Cannon88f801d2008-08-18 00:46:22 +00001560- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1561 imported into the module but exposed as part of the module's API.
1562
Brett Cannon7b96f072008-08-18 00:41:11 +00001563- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001567- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1568
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001569- Issue #3575: Incremental decoder's decode function now takes bytearray
1570 by using 's*' instead of 't#'.
1571
Jesus Cea585ad8a2009-07-02 15:37:21 +00001572- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001573 fails unicode conversion on 2nd parameter. (windows only)
1574
Facundo Batista94f243a2008-08-17 03:38:39 +00001575- Issue 2464. urllib2 now supports a malformation in the URL received
1576 in a redirect.
1577
Brett Cannonabe423e2008-08-16 21:47:07 +00001578- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001579 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001580
Facundo Batistaeb90b782008-08-16 14:44:07 +00001581- Issue #2776: fixed small issue when handling an URL with double slash
1582 after a 302 response in the case of not going through a proxy.
1583
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001584- Issue #2676: in the email package, content-type parsing was hanging on
1585 pathological input because of quadratic or exponential behaviour of a

Antoine Pitroude781a42008-08-09 12:43:23 +00001629 asking for a specific length. This problem only affected files opened

1673
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001674- Issue #643841: The language reference now provides more detailed

1686-----------------
1687
Georg Brandl3e483f62008-07-16 22:57:41 +00001688- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1689 its methods now allow for items objects that can be converted to
1690 an integer using operator.index().
1691
Mark Dickinson64b7e502008-07-16 09:40:03 +00001692- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1693 produced a ValueError instead of giving the correct float.
1694
Eric Smitha5fa5a22008-07-16 00:11:49 +00001695- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1696 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1697
Mark Dickinson7103aa42008-07-15 19:08:33 +00001698- Issue #3008: the float type has a new instance method 'float.hex'
1699 and a new class method 'float.fromhex' to convert floating-point
1700 numbers to and from hexadecimal strings, respectively.
1701
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001702- Issue #2235: __hash__ is once again inherited by default. To allow
1703 collections.Hashable to remain meaningful in the presence of the
1704 default hash implementation (object.__hash__), it is now possible
1705 to explicit block inheritance of hash by setting __hash__=None at
1706 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1707 level.
1708
Nick Coghlanb028f502008-07-13 14:52:36 +00001709- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1710 the parent module cannot be found while performing an absolute import.
1711 This means that an incorrectly defined __package__ attribute will
1712 now only prevent relative imports in that module rather than causing
1713 all imports from that module to fail.
1714
Nick Coghlan14ff9942008-07-08 14:21:42 +00001715- Issue #2517: Allow unicode messages in Exceptions again by correctly

1725 another thread's dictionary.
1726
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001727- Issue #3004: Minor change to slice.indices(): the start and stop
1728 arguments are now treated identically, making the behaviour easier
1729 to describe and understand. For example, slice(None, -10,
1730 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1731 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1732 10, -1).
1733
Georg Brandl278fc502008-07-19 12:46:12 +00001734- Issue #3219: Calling a function with repeated keyword arguments,
1735 f(a=2, a=23), would not cause a syntax error. This was a regression
1736 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001737
Georg Brandl278fc502008-07-19 12:46:12 +00001738- Issue #2862: Make int and float freelist management consistent with
1739 other freelists. Changes their CompactFreeList apis into

1746 api functions without holding the GIL, which could lead to a fatal
1747 error when they failed.
1748
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001749- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001774- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1775 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001776 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001777 content-length. The problem had been corrected in the 2.4 branch, but never
1778 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001793- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1795
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001796- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Vinay Sajip9828b7e2008-06-17 11:04:02 +00002164- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002165 environment to control the '-arch' flags that are used to build
2166 an extension. This was added for compatibility with Apple's build
2167 of Python.
2168
2169- The bundled OSX-specific copy of libbffi is now in sync with the version
2170 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
2171
Georg Brandl25c34082008-08-18 23:09:49 +00002172- The threading module gained aliases for names that will be removed in the

Brett Cannonb61d8012008-05-11 23:39:04 +00002182- ``Lib/lib-old`` is now added to sys.path.
2183
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002184- On MacOS X it is now possible to install the framework in 64-bit
2185 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002186 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002187
2188 This is controlled by the configure argument ``--with-universal-archs``:
2189
2190 - ``--with-universal-archs=all``: install 4-way universal
2191
2192 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2193
2194 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2195
2196 This option should be used in combination with ``--enable-universalsdk=``.
2197
2198 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002248- Issue #1631171: Re-implement the 'warnings' module in C (the
2249 original Python code has been kept as backup). This will allow for
2250 using the 'warning's machinery in such places as the parser where
2251 use of pure Python code is not possible. Both the ``showarning()``
2252 and ``formatwarning()`` gain an optional 'line' argument which is
2253 not called by default for backwards-compatibility reasons. Setting
2254 ``warnings.showwarning()`` to an implementation that lacks support
2255 for the ``line`` argument will raise a DeprecationWarning.

2279
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002280- The getpass module has been improved on Unix. It now uses /dev/tty
2281 by default and uses stderr instead of stdout. A GetPassWarning is
2282 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002297- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002298 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002318- Issue #2550: The approach used by client/server code for obtaining
2319 ports to listen on in network-oriented tests has been refined in an
2320 effort to facilitate running multiple instances of the entire
2321 regression test suite in parallel without issue.
2322 test_support.bind_port() has been fixed such that it will always
2323 return a unique port -- which wasn't always the case with the
2324 previous implementation, especially if socket options had been set
2325 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2326 new implementation of bind_port() will actually raise an exception
2327 if it is passed an AF_INET/SOCK_STREAM socket with either the
2328 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2329 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2330 the socket it's been passed. This currently only applies to
2331 Windows. This option prevents any other sockets from binding to the
2332 host/port we've bound to, thus removing the possibility of the
2333 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2334 when a second SOCK_STREAM socket binds and accepts to a host/port
2335 that's already been bound by another socket. The optional preferred
2336 port parameter to bind_port() has been removed. Under no
2337 circumstances should tests be hard coding ports!
2338
2339 test_support.find_unused_port() has also been introduced, which will
2340 pass a temporary socket object to bind_port() in order to obtain an
2341 unused port. The temporary socket object is then closed and
2342 deleted, and the port is returned. This method should only be used
2343 for obtaining an unused port in order to pass to an external program
2344 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2345 a parameter to a server-oriented class that doesn't give you direct
2346 access to the underlying socket used.
2347
2348 Finally, test_support.HOST has been introduced, which should be used
2349 for the host argument of any relevant socket calls (i.e. bind and
2350 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002351
2352 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002353 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002354 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2355 test_asynchat and test_socket_ssl.
2356
Georg Brandl3ee81df2008-05-17 18:14:43 +00002357 It is now possible for multiple instances of the regression test
2358 suite to run in parallel without issue.

2624Core and builtins
2625-----------------
2626
Fred Drakea8ee94b2008-03-01 02:45:07 +00002627- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002628 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002630- Issue #2067: file.__exit__() now calls subclasses' close() method.
2631
2632- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002633
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002634- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002635 issue 215555 for a discussion.
2636
Eric Smitha73fbe72008-02-23 03:09:44 +00002637- Added the future_builtins module, which contains hex() and oct().
2638 These are the PEP 3127 version of these functions, designed to be
2639 compatible with the hex() and oct() builtins from Python 3.0. They
2640 differ slightly in their output formats from the existing, unchanged
2641 Python 2.6 builtins. The expected usage of the future_builtins
2642 module is:
2643 from future_builtins import hex, oct
2644
Eric Smith7ef40bf2008-02-20 23:34:22 +00002645- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2646 exponents for exponents with absolute value < 100. Follows C99
2647 standard. This is a change on Windows, which would use 3 digits.
2648 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2649 so that any alterations it does to the resulting string will be
2650 available in stringlib/formatter.h (for float.__format__).
2651
Eric Smith5a3c1352008-02-19 13:21:56 +00002652- Implemented PEP 3101, Advanced String Formatting. This adds a new
2653 builtin format(); a format() method for str and unicode; a
2654 __format__() method to object, str, unicode, int, long, float, and
2655 datetime; the class string.Formatter; and the C API
2656 PyObject_Format().
2657
Georg Brandl3ee81df2008-05-17 18:14:43 +00002658- Fixed several potential crashes, all caused by specially crafted
2659 __del__ methods exploiting objects in temporarily inconsistent
2660 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002661
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002662- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002663 prevent a possible crash: an Abstract Base Class would try to access
2664 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002665

2667 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002669- Clear all free lists during a gc.collect() of the highest generation
2670 in order to allow pymalloc to free more arenas. Python may give back
2671 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002672
Georg Brandl3ee81df2008-05-17 18:14:43 +00002673- Issue #2045: Fix an infinite recursion triggered when printing a
2674 subclass of collections.defaultdict, if its default_factory is set
2675 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002676
Christian Heimesf75dbef2008-02-08 00:11:31 +00002677- Fixed a minor memory leak in dictobject.c. The content of the free
2678 list was not freed on interpreter shutdown.
2679
Georg Brandl3ee81df2008-05-17 18:14:43 +00002680- Limit free list of method and builtin function objects to 256
2681 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002682
Georg Brandl3ee81df2008-05-17 18:14:43 +00002683- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2684 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002685 to compact the internal free lists of pre-allocted ints and floats.
2686
Georg Brandl3ee81df2008-05-17 18:14:43 +00002687- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2688 calls. Python expected the return type int but the fork familie
2689 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002690
Georg Brandl3ee81df2008-05-17 18:14:43 +00002691- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2692 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002693
Georg Brandl3ee81df2008-05-17 18:14:43 +00002694- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2695 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002696
Georg Brandl3ee81df2008-05-17 18:14:43 +00002697- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2698 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002700- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2701 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002702
Georg Brandl3ee81df2008-05-17 18:14:43 +00002703- Patch #1473257: generator objects gain a gi_code attribute. This is
2704 the same object as the func_code attribute of the function that
2705 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002706
Georg Brandl3ee81df2008-05-17 18:14:43 +00002707- Issue #1920: "while 0" statements were completely removed by the
2708 compiler, even in the presence of an "else" clause, which is
2709 supposed to be run when the condition is false. Now the compiler
2710 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002711
Guido van Rossumeead05f2008-01-24 18:21:02 +00002712- A few crashers fixed: weakref_in_del.py (issue #1377858);
2713 loosing_dict_ref.py (issue #1303614, test67.py);
2714 borrowed_ref_[34].py (not in tracker).
2715
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002716- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002717 suppressed while an extension is loaded by calling SetErrorMode in
2718 dynload_win.c. The error is still reported properly.
2719
Georg Brandl3ee81df2008-05-17 18:14:43 +00002720- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002721 several extension methods and modules do not work without unicode
2722 support.
2723
Georg Brandl26543b12008-01-21 18:36:51 +00002724- Issue #1882: when compiling code from a string, encoding cookies in the
2725 second line of code were not always recognized correctly.
2726
Georg Brandl14404b62008-01-19 19:27:05 +00002727- Issue #1679: "0x" was taken as a valid integer literal.
2728
Georg Brandl6caad7d2008-01-26 14:19:22 +00002729- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002730 added.
2731
Christian Heimesc94e2b52008-01-14 04:13:37 +00002732- sys.float_info / PyFloat_GetInfo: The floating point information
2733 object was converted from a dict to a specialized structseq object.
2734
Georg Brandl3ee81df2008-05-17 18:14:43 +00002735- Patch #1816: Added sys.flags structseq. It exposes the status of
2736 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002737
Georg Brandl3ee81df2008-05-17 18:14:43 +00002738- Objects/structseq.c: Implemented new structseq representation. The
2739 patch makes structseqs (e.g. the return value of os.stat) more
2740 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002741
Georg Brandl3ee81df2008-05-17 18:14:43 +00002742- Patch #1700288: added a type attribute cache that caches method
2743 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002744
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002745- Bug #1776: __import__() no longer accepts filenames on any platform.
2746 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002747
Georg Brandlaed6c662008-01-07 17:25:53 +00002748- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2749
Georg Brandl3ee81df2008-05-17 18:14:43 +00002750- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2751 envvar and sys.dont_write_bytecode attribute. All these can be set
2752 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002753
Georg Brandl3ee81df2008-05-17 18:14:43 +00002754- Improve some exception messages when Windows fails to load an
2755 extension module. Now we get for example '%1 is not a valid Win32
2756 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002757

Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2761 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002762
Christian Heimes0a8143f2007-12-18 23:22:54 +00002763- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002764 and INF. float("nan"), float("inf") and float("-inf") now work on
2765 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002766
Georg Brandl3ee81df2008-05-17 18:14:43 +00002767- Compiler now generates simpler and faster code for dictionary
2768 literals. The oparg for BUILD_MAP now indicates an estimated
2769 dictionary size. There is a new opcode, STORE_MAP, for adding
2770 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002771

Georg Brandl3ee81df2008-05-17 18:14:43 +00002799- Patch #1739468: Directories and zipfiles containing a __main__.py
2800 file can now be directly executed by passing their name to the
2801 interpreter. The directory/zipfile is automatically inserted as the
2802 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002803
Georg Brandl3ee81df2008-05-17 18:14:43 +00002804- Issue #1265: Fix a problem with sys.settrace, if the tracing
2805 function uses a generator expression when at the same time the
2806 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002807
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002808- sets and frozensets now have an isdisjoint() method.
2809

2811
Neal Norwitz44f326e2007-10-05 05:29:17 +00002812- Fix warnings found by the new version of the Coverity checker.
2813
Georg Brandl3ee81df2008-05-17 18:14:43 +00002814- The enumerate() builtin function is no longer bounded to sequences
2815 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2816 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002817
Georg Brandl3ee81df2008-05-17 18:14:43 +00002818- Issue #1686386: Tuple's tp_repr did not take into account the
2819 possibility of having a self-referential tuple, which is possible
2820 from C code. Nor did object's tp_str consider that a type's tp_str
2821 could do something that could lead to an inifinite recursion.
2822 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2823 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002824
Georg Brandl3ee81df2008-05-17 18:14:43 +00002825- Issue #1164: It was possible to trigger deadlock when using the
2826 'print' statement to write to a file since the GIL was not released
2827 as needed. Now PyObject_Print() does the right thing along with
2828 various tp_print implementations of the built-in types and those in
2829 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002830
Georg Brandl3ee81df2008-05-17 18:14:43 +00002831- Issue #1147: Exceptions were directly allowing string exceptions in
2832 their throw() method even though string exceptions no longer
2833 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002834
Georg Brandl3ee81df2008-05-17 18:14:43 +00002835- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002837
Brett Cannon1e534b52007-09-07 04:18:30 +00002838- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002839 PyObject_Call() never calling back out to Python code to trigger
2840 recursion depth updates/checks. Required the creation of a static
2841 RuntimeError instance in case normalizing an exception put the
2842 recursion check value past its limit. Fixes crashers
2843 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002844

Neal Norwitz0ac60192007-05-27 04:08:54 +00002858- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002859 __*__ attributes. (Some already existed, e.g., __doc__ and
2860 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002861
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002862- Add -3 option to the interpreter to warn about features that are
2863 deprecated and will be changed/removed in Python 3.0.
2864
Georg Brandl2134e752007-05-21 20:34:16 +00002865- Patch #1686487: you can now pass any mapping after '**' in function
2866 calls.
2867
Collin Winter62903052007-05-18 23:11:24 +00002868- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002869 "except E as target:". This is to provide forwards compatibility
2870 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002871
Brett Cannon229cee22007-05-05 01:34:02 +00002872- Deprecate BaseException.message as per PEP 352.
2873
Georg Brandl3ee81df2008-05-17 18:14:43 +00002874- Issue #1303614: don't expose object's __dict__ when the dict is

2876
Vinay Sajip8549ce32007-05-06 17:53:37 +00002877- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002878 setting a plain string, ie don't expand to single letter identifiers.
2879
Raymond Hettinger13936692007-04-11 18:40:58 +00002880- Request #1191699: Slices can now be pickled.
2881
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002882- Request #1193128: str.translate() now allows a None argument for

2884 remaining characters.
2885
Georg Brandl5cb76c12007-03-21 09:00:39 +00002886- Patch #1682205: a TypeError while unpacking an iterable is no longer
2887 masked by a generic one with the message "unpack non-sequence".
2888
Neal Norwitzaa754b72007-03-21 06:39:48 +00002889- Remove unused file Python/fmod.c.
2890
Guido van Rossum143b5642007-03-23 04:58:42 +00002891- Bug #1683368: The object.__init__() and object.__new__() methods are
2892 now stricter in rejecting excess arguments. The only time when
2893 either allows excess arguments is when it is not overridden and the
2894 other one is. For backwards compatibility, when both are
2895 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002896 warning later). Also, type.__init__() insists on the same signature
2897 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002899- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2900 object to complex using its __complex__() method before falling back
2901 to the __float__() method. Therefore, the functions in the cmath
2902 module now can operate on objects that define a __complex__()
2903 method.

2922 case, even when converting the value to a string failed.
2923
Georg Brandl871f1bc2007-03-12 13:17:36 +00002924- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002925 its argument, if it exists. If not, it will work like before. This
2926 allows customizing the output of dir() in the presence of a
2927 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002939- Patch #703779: unset __file__ in __main__ after running a file. This

3010 embedded in the string to convert.
3011
Georg Brandl846f73a2006-10-08 07:11:54 +00003012- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003451 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003492 AttributeError instead of an IOError when the server's response

Georg Brandl3ee81df2008-05-17 18:14:43 +00003977 time so that opening a database previously created with the DB_DUP
3978 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3979 opens. Specifically: dictionary assignment to a DB object will
3980 replace all values for a given key when the database allows
3981 duplicate values. DB users should use DB.put(k, v) when they want
3982 to store duplicates; not DB[k] = v.

3989 characters with ASCII value less than 32. Also, it correctly quotes
3990 dots only if they occur on a single line, as opposed to the previous
3991 behavior of quoting dots if they are the second character of any
3992 line.
