733 This prevents user-created self-referencing ordered dictionaries from
734 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001196- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1197 start byte and the continuation byte(s) are now considered invalid, instead
1198 of the number of bytes specified by the start byte.
1199 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1200 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1201 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1202 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001204- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001205 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1206 arises from the "Overriding __eq__ blocks inheritance ..." warning
1207 when turned into an exception: in this case the exception simply
1208 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001210- Issue #8748: Fix two issues with comparisons between complex and integer
1211 objects. (1) The comparison could incorrectly return True in some cases
1212 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1213 (2) The comparison raised an OverflowError for large integers, leading
1214 to unpredictable exceptions when combining integers and complex objects
1215 in sets or dicts.
1216
Mark Dickinson81336372010-05-30 12:12:25 +00001217- Issue #5211: Implicit coercion for the complex type is now completely
1218 removed. (Coercion for arithmetic operations was already removed in 2.7
1219 alpha 4, but coercion for rich comparisons was accidentally left in.)
1220
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001221- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
1222 and error handler, instead of writing to the C stderr file in utf-8
1223
Georg Brandlfee0f442010-05-22 21:26:21 +00001224- Issue #7902: When using explicit relative import syntax, don't try implicit

Georg Brandlfee0f442010-05-22 21:26:21 +00001456- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
1457 the method could block indefinitely if called just before the event loop

Antoine Pitroufc69af12010-04-24 20:04:58 +00001461- Issue #5103: SSL handshake would ignore the socket timeout and block
1462 indefinitely if the other end didn't respond.
1463
Georg Brandlfee0f442010-05-22 21:26:21 +00001464- The do_handshake() method of SSL objects now adjusts the blocking mode of the

1583
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001584- Issue #8329: Don't return the same lists from select.select when no fds are
1585 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00001597- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1598 with a non-empty format string. This is an effort to future-proof user
1599 code. If a derived class does not currently implement __format__ but later
1600 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001601 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001602 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001652- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1653 InvalidOperation instead of returning False. (Comparisons involving a quiet
1654 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1655 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001657- Issue #2531: Comparison operations between floats and Decimal instances now
1658 return a result based on the numeric values of the operands; previously they
1659 returned an arbitrary result based on the relative ordering of id(float) and
1660 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001674- Comparisons using one of <, <=, >, >= between a complex instance and a
1675 Fractions instance now raise TypeError instead of returning True/False. This
1676 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1677 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002095 file position when calling `truncate()`. It would previously change the file
2096 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002097 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2098

2100 class used to represent files stored inside an archive. The new
2101 implementation is significantly faster and can be wrapped in a

2103 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2193
Georg Brandlba83f822010-03-14 09:50:54 +00002194- The ``__complex__()`` method is now looked up on the class of instances to
2195 make it consistent with other special methods.

2199
Mark Dickinson1b34d252010-01-01 17:27:30 +00002200- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002201 DeprecationWarning when passed a float argument where an integer was expected.
2202 These functions and methods now raise TypeError instead. The majority of the
2203 effects of this change are in the extension modules, but some core functions
2204 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2205 and many unicode/str methods.

2219 of integers: the result of a/b is now correctly rounded for ints a and b (at
2220 least on IEEE 754 platforms), and in particular does not depend on the
2221 internal representation of a long.

2229
Georg Brandlba83f822010-03-14 09:50:54 +00002230 These executables now work properly with the arch(1) command: ``arch -ppc
2231 python`` will start a universal binary version of python in PPC mode (unlike
2232 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00002255 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

2389 decimal string that's guaranteed to round back to x under correct rounding
2390 (with round-half-to-even rounding mode). Previously it gave a string based on
2391 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2392 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2393 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002395- Issue #7117: On almost all platforms: float-to-string and string-to-float
2396 conversions within Python are now correctly rounded. Places these conversions
2397 occur include: str for floats and complex numbers; the float and complex
2398 constructors; old-style and new-style numeric formatting; serialization and
2399 deserialization of floats and complex numbers using marshal, pickle and json;
2400 parsing of float and imaginary literals in Python code; Decimal-to-float
2401 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002402
Georg Brandlba83f822010-03-14 09:50:54 +00002403 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2404 providing correctly-rounded strtod and dtoa C functions. This code is
2405 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2406 the C compiler. There may be a small number of platforms on which correct
2407 operation of this code cannot be guaranteed, so the code is not used: notably,
2408 this applies to platforms where the C double format is not IEEE 754 binary64,
2409 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2410 and Python's configure script is unable to determine how to change the FPU
2411 precision. On these platforms conversions use the platform strtod and dtoa,
2412 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002414- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2415 uses the correctly-rounded string <-> float conversions described above (when
2416 available), and so produces correctly rounded results that will display nicely
2417 under the float repr. There are two related small changes: (1) round now
2418 accepts any class with an ``__index__()`` method for its second argument (but
2419 no longer accepts floats for the second argument), and (2) an excessively
2420 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2421 raises an exception.

2800 this code path is really executed because I cannot move to such directory on

2827 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

4004 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4005 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004204- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

4206 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4207 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00004305 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4306 for catch_warnings() also led to an improvement in the raising of a
4307 DeprecationWarning related to warnings.warn_explicit().
4308

4334 without limit.
4335
Benjamin Peterson37346b22008-08-23 20:27:43 +00004336- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004373What's New in Python 2.6 beta 3?
4374================================
4375
Barry Warsaw07a4a382008-08-21 01:15:08 +00004376*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004377
4378Core and Builtins
4379-----------------
4380
Guido van Rossumf8402962008-08-20 15:01:50 +00004381- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4382 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4383 extensions do not automatically benefit from the class attribute
4384 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4385 to their tp_flags field if they care. This is a backwards
4386 compatibility feature; in 3.0, all types will use the cache by
4387 default.
4388
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004389- Keyword arguments can now follow starred arguments. (``f(a, *args,
4390 keyword=23)`` is now valid syntax.)
4391
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004392- ctypes function pointers that are COM methods have a boolean True
4393 value again.
4394
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004395- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4396 by denying s# to parse objects that have a releasebuffer procedure,
4397 and introducing s*.
4398
Georg Brandl1e13ea92008-08-11 09:07:59 +00004399- Issue #3537: Fix an assertion failure when an empty but presized dict
4400 object was stored in the freelist.
4401
Mark Dickinsonb6467572008-08-04 21:30:09 +00004402- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4403 ValueError consistently across platforms.
4404
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004405- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4406 (64bit Unix, for example), unichr() would truncate its argument and return
4407 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4408
Neal Norwitze7d8be82008-07-31 17:17:14 +00004409- Apply security patches from Apple.
4410
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004411- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4412 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4413
Antoine Pitrou92f82162008-07-25 22:22:08 +00004414- Issue #1819: function calls with several named parameters are now on
4415 average 35% faster (as measured by pybench).
4416
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004417- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4418 the python debugger steps into a class statement: the free variables (local
4419 variables defined in an outer scope) would be deleted from the outer scope.
4420
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004421- Issue #2620: Overflow checking when allocating or reallocating memory
4422 was not always being done properly in some python types and extension
4423 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4424 all been updated to perform better checks and places in the code that
4425 would previously leak memory on the error path when such an allocation
4426 failed have been fixed.

4429-------
4430
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004431- Issue #3612: Added some missing basic types in ctypes.wintypes.
4432
Benjamin Petersone977ad42008-08-20 01:42:01 +00004433- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4434 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4435
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004436- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4437 version reported by these tools does not necessarily follow the python
4438 version numbering scheme, so the module is less strict when parsing it.
4439
Nick Coghlanf70385a2008-08-18 12:42:46 +00004440- Issue #2235: Added Py3k warnings for types which will become unhashable
4441 under the stricter __hash__ inheritance rules in 3.0. Several types
4442 which did not meet the rules for hash invariants and were already
4443 unhashable in 3.0 have now been explicitly flagged as unhashable in
4444 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4445 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4446
Brett Cannon88f801d2008-08-18 00:46:22 +00004447- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4448 imported into the module but exposed as part of the module's API.
4449
Brett Cannon7b96f072008-08-18 00:41:11 +00004450- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4451
Brett Cannon46225e72008-08-18 00:36:52 +00004452- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004454- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4455
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004456- Issue #3575: Incremental decoder's decode function now takes bytearray
4457 by using 's*' instead of 't#'.
4458
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004459- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004460 fails unicode conversion on 2nd parameter. (windows only)
4461
Georg Brandl222e2082010-08-01 22:27:39 +00004462- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004463 in a redirect.
4464
Brett Cannonabe423e2008-08-16 21:47:07 +00004465- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004466 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004467
Facundo Batistaeb90b782008-08-16 14:44:07 +00004468- Issue #2776: fixed small issue when handling an URL with double slash
4469 after a 302 response in the case of not going through a proxy.
4470
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004471- Issue #2676: in the email package, content-type parsing was hanging on
4472 pathological input because of quadratic or exponential behaviour of a
4473 regular expression.
4474
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004475- Issue #3476: binary buffered reading through the new "io" library is now
4476 thread-safe.
4477
Brett Cannonbf3157b2008-08-14 05:00:03 +00004478- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4479 since mimetools itself is deprecated. Because modules are cached, all
4480 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4481
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004482- Issue #3134: shutil referenced undefined WindowsError symbol.
4483
Robert Schuppenies14646332008-08-10 11:01:53 +00004484- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4485 menu entries were not deleted.
4486
Brett Cannon83e81842008-08-09 23:30:55 +00004487- Copied the implementation of reduce() to _functools.reduce() to have a
4488 version that did not raise a DeprecationWarning under -3.
4489
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004490- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4491 a MemoryError rather than silently stop the iteration.
4492
Guido van Rossum59ce9012008-08-09 14:55:34 +00004493- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4494 to _sre.compile() will now be rejected. This should not affect anybody
4495 since the re.compile() function never generates invalid re-bytecode.
4496
Skip Montanaroa032bf42008-08-08 22:52:51 +00004497- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4498 upon first access it can be automatically initialized from the csv file if
4499 it wasn't initialized during instantiation.
4500
Brett Cannon3aa2a492008-08-06 22:28:09 +00004501- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4502 the reload() built-in has been removed.
4503
Brett Cannon7e30b672008-08-04 21:52:25 +00004504- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004505 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4508 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4509 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4510 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Antoine Pitroude781a42008-08-09 12:43:23 +00004516 asking for a specific length. This problem only affected files opened
4517 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004518
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004519- Issue #3449: Update decimal module to use most recent specification
4520 (v. 1.68) and tests (v. 2.58) from IBM.

4573-----------------
4574
Georg Brandl3e483f62008-07-16 22:57:41 +00004575- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4576 its methods now allow for items objects that can be converted to
4577 an integer using operator.index().
4578
Mark Dickinson64b7e502008-07-16 09:40:03 +00004579- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4580 produced a ValueError instead of giving the correct float.
4581
Eric Smitha5fa5a22008-07-16 00:11:49 +00004582- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4583 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4584
Mark Dickinson7103aa42008-07-15 19:08:33 +00004585- Issue #3008: the float type has a new instance method 'float.hex'
4586 and a new class method 'float.fromhex' to convert floating-point
4587 numbers to and from hexadecimal strings, respectively.
4588
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004589- Issue #2235: __hash__ is once again inherited by default. To allow
4590 collections.Hashable to remain meaningful in the presence of the
4591 default hash implementation (object.__hash__), it is now possible
4592 to explicit block inheritance of hash by setting __hash__=None at
4593 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4594 level.
4595
Nick Coghlanb028f502008-07-13 14:52:36 +00004596- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4597 the parent module cannot be found while performing an absolute import.
4598 This means that an incorrectly defined __package__ attribute will
4599 now only prevent relative imports in that module rather than causing
4600 all imports from that module to fail.
4601
Nick Coghlan14ff9942008-07-08 14:21:42 +00004602- Issue #2517: Allow unicode messages in Exceptions again by correctly

4607 set to a custom object whose write() method happens to install
4608 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004610- Issue #3088: Corrected a race condition in classes derived from
4611 threading.local: the first member set by a thread could be saved in
4612 another thread's dictionary.
4613
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004614- Issue #3004: Minor change to slice.indices(): the start and stop
4615 arguments are now treated identically, making the behaviour easier
4616 to describe and understand. For example, slice(None, -10,
4617 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4618 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4619 10, -1).
4620
Georg Brandl278fc502008-07-19 12:46:12 +00004621- Issue #3219: Calling a function with repeated keyword arguments,
4622 f(a=2, a=23), would not cause a syntax error. This was a regression
4623 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004624
Georg Brandl278fc502008-07-19 12:46:12 +00004625- Issue #2862: Make int and float freelist management consistent with
4626 other freelists. Changes their CompactFreeList apis into
4627 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00004632- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4633 api functions without holding the GIL, which could lead to a fatal
4634 error when they failed.
4635
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004636- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004661- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4662 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004663 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004664 content-length. The problem had been corrected in the 2.4 branch, but never
4665 merged into trunk.
4666
Georg Brandle78fbcc2008-07-05 10:13:36 +00004667- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004680- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4681 handling is now the same as that of other special attributes like __name__).
4682
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004683- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00005135- Issue #1631171: Re-implement the 'warnings' module in C (the
5136 original Python code has been kept as backup). This will allow for
5137 using the 'warning's machinery in such places as the parser where
5138 use of pure Python code is not possible. Both the ``showarning()``
5139 and ``formatwarning()`` gain an optional 'line' argument which is
5140 not called by default for backwards-compatibility reasons. Setting
5141 ``warnings.showwarning()`` to an implementation that lacks support
5142 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005184- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005185 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005205- Issue #2550: The approach used by client/server code for obtaining
5206 ports to listen on in network-oriented tests has been refined in an
5207 effort to facilitate running multiple instances of the entire
5208 regression test suite in parallel without issue.
5209 test_support.bind_port() has been fixed such that it will always
5210 return a unique port -- which wasn't always the case with the
5211 previous implementation, especially if socket options had been set
5212 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5213 new implementation of bind_port() will actually raise an exception
5214 if it is passed an AF_INET/SOCK_STREAM socket with either the
5215 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5216 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5217 the socket it's been passed. This currently only applies to
5218 Windows. This option prevents any other sockets from binding to the
5219 host/port we've bound to, thus removing the possibility of the
5220 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5221 when a second SOCK_STREAM socket binds and accepts to a host/port
5222 that's already been bound by another socket. The optional preferred
5223 port parameter to bind_port() has been removed. Under no
5224 circumstances should tests be hard coding ports!
5225
5226 test_support.find_unused_port() has also been introduced, which will
5227 pass a temporary socket object to bind_port() in order to obtain an
5228 unused port. The temporary socket object is then closed and
5229 deleted, and the port is returned. This method should only be used
5230 for obtaining an unused port in order to pass to an external program
5231 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5232 a parameter to a server-oriented class that doesn't give you direct
5233 access to the underlying socket used.
5234
5235 Finally, test_support.HOST has been introduced, which should be used
5236 for the host argument of any relevant socket calls (i.e. bind and
5237 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005238
5239 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005240 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005241 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5242 test_asynchat and test_socket_ssl.
5243
Georg Brandl3ee81df2008-05-17 18:14:43 +00005244 It is now possible for multiple instances of the regression test
5245 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005524- Added the future_builtins module, which contains hex() and oct().
5525 These are the PEP 3127 version of these functions, designed to be
5526 compatible with the hex() and oct() builtins from Python 3.0. They
5527 differ slightly in their output formats from the existing, unchanged
5528 Python 2.6 builtins. The expected usage of the future_builtins
5529 module is:
5530 from future_builtins import hex, oct
5531
Eric Smith7ef40bf2008-02-20 23:34:22 +00005532- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5533 exponents for exponents with absolute value < 100. Follows C99
5534 standard. This is a change on Windows, which would use 3 digits.
5535 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5536 so that any alterations it does to the resulting string will be
5537 available in stringlib/formatter.h (for float.__format__).
5538
Eric Smith5a3c1352008-02-19 13:21:56 +00005539- Implemented PEP 3101, Advanced String Formatting. This adds a new
5540 builtin format(); a format() method for str and unicode; a
5541 __format__() method to object, str, unicode, int, long, float, and
5542 datetime; the class string.Formatter; and the C API
5543 PyObject_Format().
5544
Georg Brandl3ee81df2008-05-17 18:14:43 +00005545- Fixed several potential crashes, all caused by specially crafted
5546 __del__ methods exploiting objects in temporarily inconsistent
5547 state.

5558 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005559
Georg Brandl3ee81df2008-05-17 18:14:43 +00005560- Issue #2045: Fix an infinite recursion triggered when printing a
5561 subclass of collections.defaultdict, if its default_factory is set
5562 to a bound method.

5573
Georg Brandl3ee81df2008-05-17 18:14:43 +00005574- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5575 calls. Python expected the return type int but the fork familie
5576 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005590- Patch #1473257: generator objects gain a gi_code attribute. This is
5591 the same object as the func_code attribute of the function that
5592 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005593
Georg Brandl3ee81df2008-05-17 18:14:43 +00005594- Issue #1920: "while 0" statements were completely removed by the
5595 compiler, even in the presence of an "else" clause, which is
5596 supposed to be run when the condition is false. Now the compiler
5597 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005598

Georg Brandl3ee81df2008-05-17 18:14:43 +00005607- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005608 several extension methods and modules do not work without unicode
5609 support.
5610
Georg Brandl26543b12008-01-21 18:36:51 +00005611- Issue #1882: when compiling code from a string, encoding cookies in the
5612 second line of code were not always recognized correctly.
5613
Georg Brandl14404b62008-01-19 19:27:05 +00005614- Issue #1679: "0x" was taken as a valid integer literal.
5615
Georg Brandl6caad7d2008-01-26 14:19:22 +00005616- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005617 added.
5618
Christian Heimesc94e2b52008-01-14 04:13:37 +00005619- sys.float_info / PyFloat_GetInfo: The floating point information
5620 object was converted from a dict to a specialized structseq object.
5621
Georg Brandl3ee81df2008-05-17 18:14:43 +00005622- Patch #1816: Added sys.flags structseq. It exposes the status of
5623 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005624
Georg Brandl3ee81df2008-05-17 18:14:43 +00005625- Objects/structseq.c: Implemented new structseq representation. The
5626 patch makes structseqs (e.g. the return value of os.stat) more
5627 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005628
Georg Brandl3ee81df2008-05-17 18:14:43 +00005629- Patch #1700288: added a type attribute cache that caches method
5630 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005631
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005632- Bug #1776: __import__() no longer accepts filenames on any platform.
5633 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005634
Georg Brandlaed6c662008-01-07 17:25:53 +00005635- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5636
Georg Brandl3ee81df2008-05-17 18:14:43 +00005637- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5638 envvar and sys.dont_write_bytecode attribute. All these can be set
5639 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005640
Georg Brandl3ee81df2008-05-17 18:14:43 +00005641- Improve some exception messages when Windows fails to load an
5642 extension module. Now we get for example '%1 is not a valid Win32
5643 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005644
Georg Brandl3ee81df2008-05-17 18:14:43 +00005645- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005647- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5648 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005649
Christian Heimes0a8143f2007-12-18 23:22:54 +00005650- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005651 and INF. float("nan"), float("inf") and float("-inf") now work on
5652 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005653
Georg Brandl3ee81df2008-05-17 18:14:43 +00005654- Compiler now generates simpler and faster code for dictionary
5655 literals. The oparg for BUILD_MAP now indicates an estimated
5656 dictionary size. There is a new opcode, STORE_MAP, for adding
5657 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005667- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005668 SystemError.
5669
Nick Coghlanef01d822007-12-03 12:55:17 +00005670- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005686- Patch #1739468: Directories and zipfiles containing a __main__.py
5687 file can now be directly executed by passing their name to the
5688 interpreter. The directory/zipfile is automatically inserted as the
5689 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005690
Georg Brandl3ee81df2008-05-17 18:14:43 +00005691- Issue #1265: Fix a problem with sys.settrace, if the tracing
5692 function uses a generator expression when at the same time the
5693 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005694
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005695- sets and frozensets now have an isdisjoint() method.
5696
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005697- optimize the performance of builtin.sum().
5698
Neal Norwitz44f326e2007-10-05 05:29:17 +00005699- Fix warnings found by the new version of the Coverity checker.
5700
Georg Brandl21e99f42010-03-07 15:23:59 +00005701- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005702 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5703 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005704
Georg Brandl3ee81df2008-05-17 18:14:43 +00005705- Issue #1686386: Tuple's tp_repr did not take into account the
5706 possibility of having a self-referential tuple, which is possible
5707 from C code. Nor did object's tp_str consider that a type's tp_str
5708 could do something that could lead to an inifinite recursion.
5709 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5710 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005711
Georg Brandl3ee81df2008-05-17 18:14:43 +00005712- Issue #1164: It was possible to trigger deadlock when using the
5713 'print' statement to write to a file since the GIL was not released
5714 as needed. Now PyObject_Print() does the right thing along with
5715 various tp_print implementations of the built-in types and those in
5716 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005717
Georg Brandl3ee81df2008-05-17 18:14:43 +00005718- Issue #1147: Exceptions were directly allowing string exceptions in
5719 their throw() method even though string exceptions no longer
5720 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005721
Georg Brandl3ee81df2008-05-17 18:14:43 +00005722- Issue #1096: Prevent a segfault from getting the repr of a very
5723 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005724
Brett Cannon1e534b52007-09-07 04:18:30 +00005725- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005726 PyObject_Call() never calling back out to Python code to trigger
5727 recursion depth updates/checks. Required the creation of a static
5728 RuntimeError instance in case normalizing an exception put the
5729 recursion check value past its limit. Fixes crashers
5730 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005731
Georg Brandl3ee81df2008-05-17 18:14:43 +00005732- Patch #1031213: Decode source line in SyntaxErrors back to its

5736 with %G.
5737
Georg Brandl3ee81df2008-05-17 18:14:43 +00005738- Prevent expandtabs() on string and unicode objects from causing a
5739 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00005740

Georg Brandla5ea6892007-06-01 11:33:33 +00005744
Neal Norwitz0ac60192007-05-27 04:08:54 +00005745- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005746 __*__ attributes. (Some already existed, e.g., __doc__ and
5747 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005748
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005749- Add -3 option to the interpreter to warn about features that are
5750 deprecated and will be changed/removed in Python 3.0.
5751
Georg Brandl2134e752007-05-21 20:34:16 +00005752- Patch #1686487: you can now pass any mapping after '**' in function
5753 calls.
5754
Collin Winter62903052007-05-18 23:11:24 +00005755- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005756 "except E as target:". This is to provide forwards compatibility
5757 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005758
Brett Cannon229cee22007-05-05 01:34:02 +00005759- Deprecate BaseException.message as per PEP 352.
5760
Georg Brandl3ee81df2008-05-17 18:14:43 +00005761- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005762 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005763
Vinay Sajip8549ce32007-05-06 17:53:37 +00005764- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005765 setting a plain string, ie don't expand to single letter identifiers.
5766
Raymond Hettinger13936692007-04-11 18:40:58 +00005767- Request #1191699: Slices can now be pickled.
5768
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005769- Request #1193128: str.translate() now allows a None argument for
5770 translations that only remove characters without re-mapping the
5771 remaining characters.
5772
Georg Brandl5cb76c12007-03-21 09:00:39 +00005773- Patch #1682205: a TypeError while unpacking an iterable is no longer
5774 masked by a generic one with the message "unpack non-sequence".
5775
Neal Norwitzaa754b72007-03-21 06:39:48 +00005776- Remove unused file Python/fmod.c.
5777
Guido van Rossum143b5642007-03-23 04:58:42 +00005778- Bug #1683368: The object.__init__() and object.__new__() methods are
5779 now stricter in rejecting excess arguments. The only time when
5780 either allows excess arguments is when it is not overridden and the
5781 other one is. For backwards compatibility, when both are
5782 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005783 warning later). Also, type.__init__() insists on the same signature
5784 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005785
Georg Brandl3ee81df2008-05-17 18:14:43 +00005786- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5787 object to complex using its __complex__() method before falling back
5788 to the __float__() method. Therefore, the functions in the cmath
5789 module now can operate on objects that define a __complex__()
5790 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005791
Georg Brandl3ee81df2008-05-17 18:14:43 +00005792- Patch #1623563: allow __class__ assignment for classes with
5793 __slots__. The old and the new class are still required to have the
5794 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005795
Georg Brandl3ee81df2008-05-17 18:14:43 +00005796- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00005799- Patch #1462488: Python no longer segfaults when
5800 ``object.__reduce_ex__()`` is called with an object that is faking
5801 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005802
Georg Brandl3ee81df2008-05-17 18:14:43 +00005803- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00005806- Patch #1444529: the builtin compile() now accepts keyword arguments.
5807
Georg Brandl7b9c5552007-03-12 14:30:05 +00005808- Bug #1678647: write a newline after printing an exception in any
5809 case, even when converting the value to a string failed.
5810
Georg Brandl871f1bc2007-03-12 13:17:36 +00005811- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005812 its argument, if it exists. If not, it will work like before. This
5813 allows customizing the output of dir() in the presence of a
5814 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005815
Collin Winter276887b2007-03-12 16:11:39 +00005816- Patch #922167: Python no longer segfaults when faced with infinitely
5817 self-recursive reload() calls (as reported by bug #742342).
5818
Georg Brandl3ee81df2008-05-17 18:14:43 +00005819- Patch #1675981: remove unreachable code from ``type.__new__()``
5820 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005822- Patch #1491866: change the complex() constructor to allow
5823 parthensized forms. This means complex(repr(x)) now works instead of
5824 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005825
Georg Brandlaa2321b2007-03-07 00:40:28 +00005826- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005827 makes the filenames the warning module prints much more sensible
5828 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005829
Georg Brandl49aafc92007-03-07 00:34:46 +00005830- Variant of patch #697613: don't exit the interpreter on a SystemExit
5831 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005832 variable is given, but break into the interactive interpreter just
5833 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005838- Bug #1674503: close the file opened by execfile() in an error
5839 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005840
Georg Brandl0fca97a2007-03-05 22:28:08 +00005841- Patch #1674228: when assigning a slice (old-style), check for the
5842 sq_ass_slice instead of the sq_slice slot.
5843
Georg Brandl3ee81df2008-05-17 18:14:43 +00005844- When printing an unraisable error, don't print exceptions. before
5845 the name. This duplicates the behavior whening normally printing

Facundo Batistad918a652007-04-24 13:54:38 +00006337- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006338 the client's request was successfully received, understood, and
6339 accepted. Now in these cases no error is raised in urllib (issue
6340 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006348- Added a timeout parameter to the constructor of other protocols
6349 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6350 work started with create_connection() and timeout in httplib, and
6351 closes patch #723312.
6352
Vinay Sajip8549ce32007-05-06 17:53:37 +00006353- Patch #1676823: Added create_connection() to socket.py, which may be
6354 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006355 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006356
Martin v. Löwis0af33882007-03-23 13:27:15 +00006357- Bug #978833: Revert r50844, as it broke _socketobject.dup.

6377
Georg Brandlf66b6032007-03-14 08:27:52 +00006378- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006379 AttributeError instead of an IOError when the server's response
6380 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006381
Georg Brandl3ee81df2008-05-17 18:14:43 +00006382- Patch #957650: "%var%" environment variable references are now
6383 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00006386- Patch #1429539: pdb now correctly initializes the __main__ module
6387 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006388 correctly now.
6389

Georg Brandl3ee81df2008-05-17 18:14:43 +00006397- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00006410- Patch #1581073: add a flag to textwrap that prevents the dropping of
6411 whitespace while wrapping.
6412
Georg Brandl92a6bae2007-03-13 17:43:32 +00006413- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006414 are set for invalid interpolation sequences that would lead to
6415 errors on reading back those values.

6455 Python would crash instead of raising an error.
6456

6458 returned string up to the first NUL character.
6459

6469
Georg Brandl3ee81df2008-05-17 18:14:43 +00006470- unittest now verifies more of its assumptions. In particular,
6471 TestCase and TestSuite subclasses (not instances) are no longer
6472 accepted in TestSuite.addTest(). This should cause no
6473 incompatibility since it never made sense with ordinary subclasses
6474 -- the failure just occurred later, with a more cumbersome
6475 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00006476

6484 given a unicode argument and os.listdir() returns unicode filenames.
6485
Georg Brandl3ee81df2008-05-17 18:14:43 +00006486- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006864 time so that opening a database previously created with the DB_DUP
6865 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6866 opens. Specifically: dictionary assignment to a DB object will
6867 replace all values for a given key when the database allows
6868 duplicate values. DB users should use DB.put(k, v) when they want
6869 to store duplicates; not DB[k] = v.

6876 characters with ASCII value less than 32. Also, it correctly quotes
6877 dots only if they occur on a single line, as opposed to the previous
6878 behavior of quoting dots if they are the second character of any
6879 line.
