688 SSLSocket.sendto() to match the corresponding socket methods. Also,
689 fix various SSLSocket methods to raise socket.error rather than an

691 by Andrew Bennetts.

700
Raymond Hettinger20397532010-09-12 02:11:45 +0000701- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
702 This prevents user-created self-referencing ordered dictionaries from
703 becoming permanently uncollectable GC garbage. The downside is that
704 removing __del__ means that the internal doubly-linked list has to wait for
705 GC collection rather than freeing memory immediately when the refcnt drops
706 to zero.
707
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000708- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

711
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000712- Issue #9792: In case of connection failure, socket.create_connection()
713 would swallow the exception and raise a new one, making it impossible
714 to fetch the original errno, or to filter timeout errors. Now the
715 original error is re-raised.
716
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000717- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
718 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
719 be updated back after the system call. Original patch by Brian Brazil.
720

725 ConfigParser.write.
726
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000727- Issue #808164: Fixed socket.close to avoid references to globals, to
728 avoid issues when socket.close is called from a __del__ method.
729

735 falling into recursion.
736
R. David Murray7c4bf552010-08-25 01:45:57 +0000737- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
738 character years even if the message contains RFC822 two character years.
739
Daniel Stutzbach91287322010-08-24 21:09:30 +0000740- Issue #8750: Fixed MutableSet's methods to correctly handle
741 reflexive operations, namely x -= x and x ^= x.
742

752 module now correctly return a set. (Patch by Eli Bendersky.)
753
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000754- Issue #9617: Signals received during a low-level write operation aren't
755 ignored by the buffered IO layer anymore.
756
Benjamin Peterson52c36052010-08-21 03:03:22 +0000757- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
758 are not held onto after they are deleted elsewhere.
759
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000760- Issue #9626: the view methods for collections.OrderedDict() were returning
761 the unordered versions inherited from dict. Those methods are now
762 overridden to provide ordered views.

767
Antoine Pitroue1436d12010-08-12 15:25:51 +0000768- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
769 and a BadZipfile error is raised if it doesn't match (as used to be the
770 case in Python 2.5 and earlier).

773 original read request had been satisfied, which could block indefinitely
774 when the underlying raw IO channel was e.g. a socket. Report and original
775 patch by Jason V. Miller.
776
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000777- Issue #9551: Don't raise TypeError when setting the value to None for

797 behavior was wrong.

805 the option character for the added 'h/help' option if prefix_chars
806 does not contain a '-', instead of raising an error.

1167 of the number of bytes specified by the start byte.
1168 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1169 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001551- Issue #7301: Add environment variable $PYTHONWARNINGS.
1552
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001553- Issue #8329: Don't return the same lists from select.select when no fds are
1554 changed.
1555
Georg Brandlfee0f442010-05-22 21:26:21 +00001556- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

1565
Georg Brandlfee0f442010-05-22 21:26:21 +00001566- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1567 with a non-empty format string. This is an effort to future-proof user
1568 code. If a derived class does not currently implement __format__ but later
1569 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001570 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001571 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001604- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00001621- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1622 InvalidOperation instead of returning False. (Comparisons involving a quiet
1623 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1624 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001625
Georg Brandlfee0f442010-05-22 21:26:21 +00001626- Issue #2531: Comparison operations between floats and Decimal instances now
1627 return a result based on the numeric values of the operands; previously they
1628 returned an arbitrary result based on the relative ordering of id(float) and
1629 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001630
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001631- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001632 argument `-` which tells it to read files to compile from stdin. Each line is
1633 read on demand and the named file is compiled immediately. (Original patch by

Florent Xicluna58b65662010-03-30 16:29:03 +00001639- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1640 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001641 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00001643- Comparisons using one of <, <=, >, >= between a complex instance and a
1644 Fractions instance now raise TypeError instead of returning True/False. This
1645 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1646 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002064 file position when calling `truncate()`. It would previously change the file
2065 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002066 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2069 class used to represent files stored inside an archive. The new
2070 implementation is significantly faster and can be wrapped in a

2072 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00002155What's New in Python 2.7 alpha 2?

2161-----------------
2162
Georg Brandlba83f822010-03-14 09:50:54 +00002163- The ``__complex__()`` method is now looked up on the class of instances to
2164 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00002165
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002166- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2167 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2168
Mark Dickinson1b34d252010-01-01 17:27:30 +00002169- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002170 DeprecationWarning when passed a float argument where an integer was expected.
2171 These functions and methods now raise TypeError instead. The majority of the
2172 effects of this change are in the extension modules, but some core functions
2173 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2174 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00002175

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00002184- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
2185 used to drop the time part of the result.
2186
Georg Brandlba83f822010-03-14 09:50:54 +00002187- Issue #1811: Improve accuracy and cross-platform consistency for true division
2188 of integers: the result of a/b is now correctly rounded for ints a and b (at
2189 least on IEEE 754 platforms), and in particular does not depend on the
2190 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00002191
Georg Brandlba83f822010-03-14 09:50:54 +00002192- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
2193 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
2194 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00002195

Ronald Oussoren92919a62009-12-24 13:30:58 +00002197 executables on OSX.
2198
Georg Brandlba83f822010-03-14 09:50:54 +00002199 These executables now work properly with the arch(1) command: ``arch -ppc
2200 python`` will start a universal binary version of python in PPC mode (unlike
2201 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00002202
Georg Brandlba83f822010-03-14 09:50:54 +00002203- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
2204 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00002205

Georg Brandlba83f822010-03-14 09:50:54 +00002215- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
2216 allowing for a maximum number of tasks within the pool to be completed by the
2217 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00002223- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00002224 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
2225 alternative to cPickle if you care about performance. Patch by Florent

Ezio Melotti569e61f2009-12-30 06:14:51 +00002245 Initial patch by Brian Curtin.
2246
Georg Brandlba83f822010-03-14 09:50:54 +00002247- Distutils now correctly identifies the build architecture as "x86_64" when

Benjamin Petersonddd392c2009-12-13 19:19:07 +00002260- Issue #7349: Make methods of file objects in the io module accept None as an
2261 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
2262 the same as passing no argument.
2263
Georg Brandlba83f822010-03-14 09:50:54 +00002264- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Mark Dickinsona36507c2010-01-30 10:08:33 +00002285
Georg Brandlba83f822010-03-14 09:50:54 +00002286- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
2287 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2288 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2289 float arguments for integer format codes (other than 'L'): previously an

2291 TypeError. For the 'L' format code (which previously had no warning) there is
2292 now a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00002357- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2358 decimal string that's guaranteed to round back to x under correct rounding
2359 (with round-half-to-even rounding mode). Previously it gave a string based on
2360 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2361 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2362 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002363
Georg Brandlba83f822010-03-14 09:50:54 +00002364- Issue #7117: On almost all platforms: float-to-string and string-to-float
2365 conversions within Python are now correctly rounded. Places these conversions
2366 occur include: str for floats and complex numbers; the float and complex
2367 constructors; old-style and new-style numeric formatting; serialization and
2368 deserialization of floats and complex numbers using marshal, pickle and json;
2369 parsing of float and imaginary literals in Python code; Decimal-to-float
2370 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002371
Georg Brandlba83f822010-03-14 09:50:54 +00002372 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2373 providing correctly-rounded strtod and dtoa C functions. This code is
2374 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2375 the C compiler. There may be a small number of platforms on which correct
2376 operation of this code cannot be guaranteed, so the code is not used: notably,
2377 this applies to platforms where the C double format is not IEEE 754 binary64,
2378 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2379 and Python's configure script is unable to determine how to change the FPU
2380 precision. On these platforms conversions use the platform strtod and dtoa,
2381 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002382
Georg Brandlba83f822010-03-14 09:50:54 +00002383- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2384 uses the correctly-rounded string <-> float conversions described above (when
2385 available), and so produces correctly rounded results that will display nicely
2386 under the float repr. There are two related small changes: (1) round now
2387 accepts any class with an ``__index__()`` method for its second argument (but
2388 no longer accepts floats for the second argument), and (2) an excessively
2389 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

2740
Georg Brandlba83f822010-03-14 09:50:54 +00002741- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2742 file objects with closefd=False. The file descriptor is still kept open but
2743 the file object behaves like a closed file. The ``FileIO`` object also got a

2769 this code path is really executed because I cannot move to such directory on
2770 win2k)

2796 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004173- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4174 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4175 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4176 ``printf`` function, whereas PyString_FromFormat has an independent
4177 implementation and uses "%zd" on all platforms for size_t values.
4178 This makes a difference on win64, where ``printf`` needs "%Id" to display
4179 64bit values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004274 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4275 for catch_warnings() also led to an improvement in the raising of a
4276 DeprecationWarning related to warnings.warn_explicit().
4277
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004278- The deprecation warnings for the old camelCase threading API were removed.

4300
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004301- Issue #2975: When compiling several extension modules with Visual Studio 2008
4302 from the same python interpreter, some environment variables would grow
4303 without limit.
4304
Benjamin Peterson37346b22008-08-23 20:27:43 +00004305- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4306 exploitation of poor argument checking.
4307
Gerhard Häringef2276b2008-09-12 13:54:06 +00004308- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004342What's New in Python 2.6 beta 3?
4343================================
4344
Barry Warsaw07a4a382008-08-21 01:15:08 +00004345*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004346
4347Core and Builtins
4348-----------------
4349
Guido van Rossumf8402962008-08-20 15:01:50 +00004350- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4351 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4352 extensions do not automatically benefit from the class attribute
4353 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4354 to their tp_flags field if they care. This is a backwards
4355 compatibility feature; in 3.0, all types will use the cache by
4356 default.
4357
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004358- Keyword arguments can now follow starred arguments. (``f(a, *args,
4359 keyword=23)`` is now valid syntax.)
4360
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004361- ctypes function pointers that are COM methods have a boolean True
4362 value again.
4363
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004364- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4365 by denying s# to parse objects that have a releasebuffer procedure,
4366 and introducing s*.
4367
Georg Brandl1e13ea92008-08-11 09:07:59 +00004368- Issue #3537: Fix an assertion failure when an empty but presized dict
4369 object was stored in the freelist.
4370
Mark Dickinsonb6467572008-08-04 21:30:09 +00004371- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4372 ValueError consistently across platforms.
4373
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004374- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4375 (64bit Unix, for example), unichr() would truncate its argument and return
4376 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4377
Neal Norwitze7d8be82008-07-31 17:17:14 +00004378- Apply security patches from Apple.
4379
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004380- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4381 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4382
Antoine Pitrou92f82162008-07-25 22:22:08 +00004383- Issue #1819: function calls with several named parameters are now on
4384 average 35% faster (as measured by pybench).
4385
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004386- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4387 the python debugger steps into a class statement: the free variables (local
4388 variables defined in an outer scope) would be deleted from the outer scope.
4389
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004390- Issue #2620: Overflow checking when allocating or reallocating memory
4391 was not always being done properly in some python types and extension
4392 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4393 all been updated to perform better checks and places in the code that
4394 would previously leak memory on the error path when such an allocation
4395 failed have been fixed.

4398-------
4399
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004400- Issue #3612: Added some missing basic types in ctypes.wintypes.
4401
Benjamin Petersone977ad42008-08-20 01:42:01 +00004402- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4403 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4404
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004405- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4406 version reported by these tools does not necessarily follow the python
4407 version numbering scheme, so the module is less strict when parsing it.
4408
Nick Coghlanf70385a2008-08-18 12:42:46 +00004409- Issue #2235: Added Py3k warnings for types which will become unhashable
4410 under the stricter __hash__ inheritance rules in 3.0. Several types
4411 which did not meet the rules for hash invariants and were already
4412 unhashable in 3.0 have now been explicitly flagged as unhashable in
4413 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4414 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4415
Brett Cannon88f801d2008-08-18 00:46:22 +00004416- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4418
Brett Cannon7b96f072008-08-18 00:41:11 +00004419- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4420
Brett Cannon46225e72008-08-18 00:36:52 +00004421- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004423- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4424
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004425- Issue #3575: Incremental decoder's decode function now takes bytearray
4426 by using 's*' instead of 't#'.
4427
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004428- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004429 fails unicode conversion on 2nd parameter. (windows only)
4430
Georg Brandl222e2082010-08-01 22:27:39 +00004431- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004432 in a redirect.
4433
Brett Cannonabe423e2008-08-16 21:47:07 +00004434- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004435 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004436
Facundo Batistaeb90b782008-08-16 14:44:07 +00004437- Issue #2776: fixed small issue when handling an URL with double slash
4438 after a 302 response in the case of not going through a proxy.
4439
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004440- Issue #2676: in the email package, content-type parsing was hanging on
4441 pathological input because of quadratic or exponential behaviour of a
4442 regular expression.
4443
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004444- Issue #3476: binary buffered reading through the new "io" library is now
4445 thread-safe.
4446
Brett Cannonbf3157b2008-08-14 05:00:03 +00004447- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4448 since mimetools itself is deprecated. Because modules are cached, all
4449 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4450
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004451- Issue #3134: shutil referenced undefined WindowsError symbol.
4452
Robert Schuppenies14646332008-08-10 11:01:53 +00004453- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4454 menu entries were not deleted.
4455
Brett Cannon83e81842008-08-09 23:30:55 +00004456- Copied the implementation of reduce() to _functools.reduce() to have a
4457 version that did not raise a DeprecationWarning under -3.
4458
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004459- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4460 a MemoryError rather than silently stop the iteration.
4461
Guido van Rossum59ce9012008-08-09 14:55:34 +00004462- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4463 to _sre.compile() will now be rejected. This should not affect anybody
4464 since the re.compile() function never generates invalid re-bytecode.
4465
Skip Montanaroa032bf42008-08-08 22:52:51 +00004466- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4467 upon first access it can be automatically initialized from the csv file if
4468 it wasn't initialized during instantiation.
4469
Brett Cannon3aa2a492008-08-06 22:28:09 +00004470- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4471 the reload() built-in has been removed.
4472
Brett Cannon7e30b672008-08-04 21:52:25 +00004473- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004474 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004485 asking for a specific length. This problem only affected files opened
4486 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004487

4542-----------------
4543
Georg Brandl3e483f62008-07-16 22:57:41 +00004544- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4545 its methods now allow for items objects that can be converted to
4546 an integer using operator.index().
4547
Mark Dickinson64b7e502008-07-16 09:40:03 +00004548- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4549 produced a ValueError instead of giving the correct float.
4550
Eric Smitha5fa5a22008-07-16 00:11:49 +00004551- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4552 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4553
Mark Dickinson7103aa42008-07-15 19:08:33 +00004554- Issue #3008: the float type has a new instance method 'float.hex'
4555 and a new class method 'float.fromhex' to convert floating-point
4556 numbers to and from hexadecimal strings, respectively.
4557
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004558- Issue #2235: __hash__ is once again inherited by default. To allow
4559 collections.Hashable to remain meaningful in the presence of the
4560 default hash implementation (object.__hash__), it is now possible
4561 to explicit block inheritance of hash by setting __hash__=None at
4562 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4563 level.
4564
Nick Coghlanb028f502008-07-13 14:52:36 +00004565- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4566 the parent module cannot be found while performing an absolute import.
4567 This means that an incorrectly defined __package__ attribute will
4568 now only prevent relative imports in that module rather than causing
4569 all imports from that module to fail.
4570
Nick Coghlan14ff9942008-07-08 14:21:42 +00004571- Issue #2517: Allow unicode messages in Exceptions again by correctly
4572 bypassing the instance dictionary when looking up __unicode__ on
4573 new-style classes.
4574
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004575- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4576 set to a custom object whose write() method happens to install
4577 another file in sys.stdout.
4578
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004579- Issue #3088: Corrected a race condition in classes derived from
4580 threading.local: the first member set by a thread could be saved in
4581 another thread's dictionary.
4582
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004583- Issue #3004: Minor change to slice.indices(): the start and stop
4584 arguments are now treated identically, making the behaviour easier
4585 to describe and understand. For example, slice(None, -10,
4586 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4587 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4588 10, -1).
4589
Georg Brandl278fc502008-07-19 12:46:12 +00004590- Issue #3219: Calling a function with repeated keyword arguments,
4591 f(a=2, a=23), would not cause a syntax error. This was a regression
4592 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004593
Georg Brandl278fc502008-07-19 12:46:12 +00004594- Issue #2862: Make int and float freelist management consistent with
4595 other freelists. Changes their CompactFreeList apis into
4596 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004597

4599-------
4600
Thomas Heller57adf222008-08-14 19:10:48 +00004601- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4602 api functions without holding the GIL, which could lead to a fatal
4603 error when they failed.
4604
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004605- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
4606

Jesse Noller13e9d582008-07-16 14:32:36 +00004613- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4614 ForkingPickler.register() to resolve conflict with ctypes.
4615
Vinay Sajip51e65192008-07-18 09:01:10 +00004616- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004617
Thomas Heller880f5292008-07-15 19:39:38 +00004618- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4619 a valid dlerror() message.
4620
Thomas Heller2bad6572008-07-15 17:19:50 +00004621- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4622 incomplete structure was created.
4623
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004624- Issue #3339: dummy_thread.acquire() should not return None.
4625
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004626- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4627
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004628- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004629
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004630- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4631 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004632 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004633 content-length. The problem had been corrected in the 2.4 branch, but never
4634 merged into trunk.
4635
Georg Brandle78fbcc2008-07-05 10:13:36 +00004636- Issue #2663: add filtering capability to shutil.copytree().

4639
4640- Issue #1526: Allow more than 64k files to be added to Zip64 file.
4641
4642- Issue #1746: Correct handling of zipfile archive comments (previously
4643 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004644 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004645
Vinay Sajip51e65192008-07-18 09:01:10 +00004646- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004647 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004648
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004649- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4650 handling is now the same as that of other special attributes like __name__).
4651
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004652- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4653 removal in Python 3.0 in favor of urllib2.urlopen().

4665
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00004666- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl3ee81df2008-05-17 18:14:43 +00005104- Issue #1631171: Re-implement the 'warnings' module in C (the
5105 original Python code has been kept as backup). This will allow for
5106 using the 'warning's machinery in such places as the parser where
5107 use of pure Python code is not possible. Both the ``showarning()``
5108 and ``formatwarning()`` gain an optional 'line' argument which is
5109 not called by default for backwards-compatibility reasons. Setting
5110 ``warnings.showwarning()`` to an implementation that lacks support
5111 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005174- Issue #2550: The approach used by client/server code for obtaining
5175 ports to listen on in network-oriented tests has been refined in an
5176 effort to facilitate running multiple instances of the entire
5177 regression test suite in parallel without issue.
5178 test_support.bind_port() has been fixed such that it will always
5179 return a unique port -- which wasn't always the case with the
5180 previous implementation, especially if socket options had been set
5181 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5182 new implementation of bind_port() will actually raise an exception
5183 if it is passed an AF_INET/SOCK_STREAM socket with either the
5184 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5185 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5186 the socket it's been passed. This currently only applies to
5187 Windows. This option prevents any other sockets from binding to the
5188 host/port we've bound to, thus removing the possibility of the
5189 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5190 when a second SOCK_STREAM socket binds and accepts to a host/port
5191 that's already been bound by another socket. The optional preferred
5192 port parameter to bind_port() has been removed. Under no
5193 circumstances should tests be hard coding ports!
5194
5195 test_support.find_unused_port() has also been introduced, which will
5196 pass a temporary socket object to bind_port() in order to obtain an
5197 unused port. The temporary socket object is then closed and
5198 deleted, and the port is returned. This method should only be used
5199 for obtaining an unused port in order to pass to an external program
5200 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5201 a parameter to a server-oriented class that doesn't give you direct
5202 access to the underlying socket used.
5203
5204 Finally, test_support.HOST has been introduced, which should be used
5205 for the host argument of any relevant socket calls (i.e. bind and
5206 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005207
5208 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005209 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005210 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5211 test_asynchat and test_socket_ssl.
5212
Georg Brandl3ee81df2008-05-17 18:14:43 +00005213 It is now possible for multiple instances of the regression test
5214 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005493- Added the future_builtins module, which contains hex() and oct().
5494 These are the PEP 3127 version of these functions, designed to be
5495 compatible with the hex() and oct() builtins from Python 3.0. They
5496 differ slightly in their output formats from the existing, unchanged
5497 Python 2.6 builtins. The expected usage of the future_builtins
5498 module is:
5499 from future_builtins import hex, oct
5500
Eric Smith7ef40bf2008-02-20 23:34:22 +00005501- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5502 exponents for exponents with absolute value < 100. Follows C99
5503 standard. This is a change on Windows, which would use 3 digits.
5504 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5505 so that any alterations it does to the resulting string will be
5506 available in stringlib/formatter.h (for float.__format__).
5507
Eric Smith5a3c1352008-02-19 13:21:56 +00005508- Implemented PEP 3101, Advanced String Formatting. This adds a new
5509 builtin format(); a format() method for str and unicode; a
5510 __format__() method to object, str, unicode, int, long, float, and
5511 datetime; the class string.Formatter; and the C API
5512 PyObject_Format().
5513
Georg Brandl3ee81df2008-05-17 18:14:43 +00005514- Fixed several potential crashes, all caused by specially crafted
5515 __del__ methods exploiting objects in temporarily inconsistent
5516 state.

5527 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005528
Georg Brandl3ee81df2008-05-17 18:14:43 +00005529- Issue #2045: Fix an infinite recursion triggered when printing a
5530 subclass of collections.defaultdict, if its default_factory is set
5531 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005532
Christian Heimesf75dbef2008-02-08 00:11:31 +00005533- Fixed a minor memory leak in dictobject.c. The content of the free
5534 list was not freed on interpreter shutdown.
5535
Georg Brandl21e99f42010-03-07 15:23:59 +00005536- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00005538
Georg Brandl3ee81df2008-05-17 18:14:43 +00005539- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5540 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005541 to compact the internal free lists of pre-allocted ints and floats.
5542
Georg Brandl3ee81df2008-05-17 18:14:43 +00005543- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5544 calls. Python expected the return type int but the fork familie
5545 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005559- Patch #1473257: generator objects gain a gi_code attribute. This is
5560 the same object as the func_code attribute of the function that
5561 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005562
Georg Brandl3ee81df2008-05-17 18:14:43 +00005563- Issue #1920: "while 0" statements were completely removed by the
5564 compiler, even in the presence of an "else" clause, which is
5565 supposed to be run when the condition is false. Now the compiler
5566 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005567
Guido van Rossumeead05f2008-01-24 18:21:02 +00005568- A few crashers fixed: weakref_in_del.py (issue #1377858);

5575
Georg Brandl3ee81df2008-05-17 18:14:43 +00005576- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005577 several extension methods and modules do not work without unicode
5578 support.
5579

5582
Georg Brandl14404b62008-01-19 19:27:05 +00005583- Issue #1679: "0x" was taken as a valid integer literal.
5584
Georg Brandl6caad7d2008-01-26 14:19:22 +00005585- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005586 added.
5587
Christian Heimesc94e2b52008-01-14 04:13:37 +00005588- sys.float_info / PyFloat_GetInfo: The floating point information

5590
Georg Brandl3ee81df2008-05-17 18:14:43 +00005591- Patch #1816: Added sys.flags structseq. It exposes the status of
5592 most command line arguments and PYTHON* environment variables.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005610- Improve some exception messages when Windows fails to load an
5611 extension module. Now we get for example '%1 is not a valid Win32
5612 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005620 and INF. float("nan"), float("inf") and float("-inf") now work on
5621 every platform with IEEE 754 semantics.

5625 dictionary size. There is a new opcode, STORE_MAP, for adding
5626 entries to the dictionary.

5656 file can now be directly executed by passing their name to the
5657 interpreter. The directory/zipfile is automatically inserted as the
5658 first entry in sys.path.

5669
Georg Brandl21e99f42010-03-07 15:23:59 +00005670- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005671 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5672 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005673
Georg Brandl3ee81df2008-05-17 18:14:43 +00005674- Issue #1686386: Tuple's tp_repr did not take into account the
5675 possibility of having a self-referential tuple, which is possible
5676 from C code. Nor did object's tp_str consider that a type's tp_str
5677 could do something that could lead to an inifinite recursion.
5678 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5679 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005680
Georg Brandl3ee81df2008-05-17 18:14:43 +00005681- Issue #1164: It was possible to trigger deadlock when using the
5682 'print' statement to write to a file since the GIL was not released
5683 as needed. Now PyObject_Print() does the right thing along with
5684 various tp_print implementations of the built-in types and those in
5685 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005686
Georg Brandl3ee81df2008-05-17 18:14:43 +00005687- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00005694- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005695 PyObject_Call() never calling back out to Python code to trigger
5696 recursion depth updates/checks. Required the creation of a static
5697 RuntimeError instance in case normalizing an exception put the
5698 recursion check value past its limit. Fixes crashers
5699 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005715 __*__ attributes. (Some already existed, e.g., __doc__ and
5716 __name__.)

5722 calls.
5723
Collin Winter62903052007-05-18 23:11:24 +00005724- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005725 "except E as target:". This is to provide forwards compatibility
5726 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005733- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005734 setting a plain string, ie don't expand to single letter identifiers.
5735
Raymond Hettinger13936692007-04-11 18:40:58 +00005736- Request #1191699: Slices can now be pickled.
5737
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005738- Request #1193128: str.translate() now allows a None argument for

5740 remaining characters.
5741
Georg Brandl5cb76c12007-03-21 09:00:39 +00005742- Patch #1682205: a TypeError while unpacking an iterable is no longer

5746
Guido van Rossum143b5642007-03-23 04:58:42 +00005747- Bug #1683368: The object.__init__() and object.__new__() methods are
5748 now stricter in rejecting excess arguments. The only time when
5749 either allows excess arguments is when it is not overridden and the
5750 other one is. For backwards compatibility, when both are
5751 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005752 warning later). Also, type.__init__() insists on the same signature
5753 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005755- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5756 object to complex using its __complex__() method before falling back
5757 to the __float__() method. Therefore, the functions in the cmath
5758 module now can operate on objects that define a __complex__()
5759 method.

5776
Georg Brandl7b9c5552007-03-12 14:30:05 +00005777- Bug #1678647: write a newline after printing an exception in any
5778 case, even when converting the value to a string failed.
5779
Georg Brandl871f1bc2007-03-12 13:17:36 +00005780- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005781 its argument, if it exists. If not, it will work like before. This
5782 allows customizing the output of dir() in the presence of a
5783 __getattr__().

5792 parthensized forms. This means complex(repr(x)) now works instead of
5793 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005794
Georg Brandlaa2321b2007-03-07 00:40:28 +00005795- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005796 makes the filenames the warning module prints much more sensible
5797 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005810- Patch #1674228: when assigning a slice (old-style), check for the
5811 sq_ass_slice instead of the sq_slice slot.
5812
Georg Brandl3ee81df2008-05-17 18:14:43 +00005813- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00006383 are set for invalid interpolation sequences that would lead to

6440 TestCase and TestSuite subclasses (not instances) are no longer
6441 accepted in TestSuite.addTest(). This should cause no

6443 -- the failure just occurred later, with a more cumbersome
6444 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006731 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00006733 does not claim to support starttls. Adds the
6734 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006832- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006833 time so that opening a database previously created with the DB_DUP
6834 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6835 opens. Specifically: dictionary assignment to a DB object will
6836 replace all values for a given key when the database allows
6837 duplicate values. DB users should use DB.put(k, v) when they want
6838 to store duplicates; not DB[k] = v.

7194 of w# format code incorrectly truncated the length to an int, even
7195 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7196 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007226- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7227 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007228
