686 This prevents user-created self-referencing ordered dictionaries from
687 becoming permanently uncollectable GC garbage. The downside is that
688 removing __del__ means that the internal doubly-linked list has to wait for
689 GC collection rather than freeing memory immediately when the refcnt drops
690 to zero.

1151 of the number of bytes specified by the start byte.
1152 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1153 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1165 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

1534
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001535- Issue #7301: Add environment variable $PYTHONWARNINGS.
1536
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001537- Issue #8329: Don't return the same lists from select.select when no fds are
1538 changed.
1539
Georg Brandlfee0f442010-05-22 21:26:21 +00001540- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001541 on 64-bit machines. The shift count for either left or right shift is
1542 permitted to be up to sys.maxsize.
1543
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001544- Ensure that tokenization of identifiers is not affected by locale.

1549
Georg Brandlfee0f442010-05-22 21:26:21 +00001550- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1551 with a non-empty format string. This is an effort to future-proof user
1552 code. If a derived class does not currently implement __format__ but later
1553 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001554 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001555 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001588- Issue #8257: The Decimal construct now accepts a float instance directly,
1589 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001590
1591 >>> Decimal(1.1)
1592 Decimal('1.100000000000000088817841970012523233890533447265625')
1593
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001594- collections.Counter() now supports a subtract() method.
1595
Georg Brandlfee0f442010-05-22 21:26:21 +00001596- The functools module now has a total_ordering() class decorator to simplify
1597 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00001605- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1606 InvalidOperation instead of returning False. (Comparisons involving a quiet
1607 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1608 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001609
Georg Brandlfee0f442010-05-22 21:26:21 +00001610- Issue #2531: Comparison operations between floats and Decimal instances now
1611 return a result based on the numeric values of the operands; previously they
1612 returned an arbitrary result based on the relative ordering of id(float) and
1613 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001614
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001615- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001616 argument `-` which tells it to read files to compile from stdin. Each line is
1617 read on demand and the named file is compiled immediately. (Original patch by
1618 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00001623- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1624 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001625 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00001627- Comparisons using one of <, <=, >, >= between a complex instance and a
1628 Fractions instance now raise TypeError instead of returning True/False. This
1629 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1630 <=> complex, and complex <=> complex comparisons.

1735 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1736 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001737 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1738 inconsistent: __int__ was used for some integer codes but not for others, and
1739 the set of integer codes for which it was used differed between native packing
1740 and standard packing.)

1993 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1994 returning NULL. The macro now returns a statically allocated empty string
1995 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002048 file position when calling `truncate()`. It would previously change the file
2049 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002050 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2053 class used to represent files stored inside an archive. The new
2054 implementation is significantly faster and can be wrapped in a

2056 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002067- Issue #7748: Since unicode values are supported for some metadata options in
2068 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2069 encoded string for them. This ensures that the upload and register commands
2070 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00002153- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002154 DeprecationWarning when passed a float argument where an integer was expected.
2155 These functions and methods now raise TypeError instead. The majority of the
2156 effects of this change are in the extension modules, but some core functions
2157 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2158 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002341- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2342 decimal string that's guaranteed to round back to x under correct rounding
2343 (with round-half-to-even rounding mode). Previously it gave a string based on
2344 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2345 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2346 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002347
Georg Brandlba83f822010-03-14 09:50:54 +00002348- Issue #7117: On almost all platforms: float-to-string and string-to-float
2349 conversions within Python are now correctly rounded. Places these conversions
2350 occur include: str for floats and complex numbers; the float and complex
2351 constructors; old-style and new-style numeric formatting; serialization and
2352 deserialization of floats and complex numbers using marshal, pickle and json;
2353 parsing of float and imaginary literals in Python code; Decimal-to-float
2354 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002355
Georg Brandlba83f822010-03-14 09:50:54 +00002356 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2357 providing correctly-rounded strtod and dtoa C functions. This code is
2358 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2359 the C compiler. There may be a small number of platforms on which correct
2360 operation of this code cannot be guaranteed, so the code is not used: notably,
2361 this applies to platforms where the C double format is not IEEE 754 binary64,
2362 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2363 and Python's configure script is unable to determine how to change the FPU
2364 precision. On these platforms conversions use the platform strtod and dtoa,
2365 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002367- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2368 uses the correctly-rounded string <-> float conversions described above (when
2369 available), and so produces correctly rounded results that will display nicely
2370 under the float repr. There are two related small changes: (1) round now
2371 accepts any class with an ``__index__()`` method for its second argument (but
2372 no longer accepts floats for the second argument), and (2) an excessively
2373 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2374 raises an exception.

2524 of 12. Previously, the behavior the same but with a default precision of 6.
2525 This more closely matches ``str()``, and reduces surprises when adding

2753 this code path is really executed because I cannot move to such directory on

2780 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

4156
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004157- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4158 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4159 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4160 ``printf`` function, whereas PyString_FromFormat has an independent
4161 implementation and uses "%zd" on all platforms for size_t values.
4162 This makes a difference on win64, where ``printf`` needs "%Id" to display
4163 64bit values.

4169 object; previously an int would be returned for small values. the __long__

Antoine Pitrou0668c622008-08-26 22:42:08 +00004183 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4184 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4185 when given a tuple of classes as second argument, were looking up
4186 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4187 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004258 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4259 for catch_warnings() also led to an improvement in the raising of a
4260 DeprecationWarning related to warnings.warn_explicit().
4261
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004262- The deprecation warnings for the old camelCase threading API were removed.

4267
Christian Heimes1cc69632008-08-22 20:10:27 +00004268- Fixed two format strings in the _collections module.
4269

Gregory P. Smithd7122032008-09-02 05:36:11 +00004273- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
4274 non-integer floating point number.
4275
Vinay Sajip65d66e12008-09-04 07:31:21 +00004276- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

Jesse Noller438195f2009-01-18 21:04:36 +00004282- Issue #4301: Patch the logging module to add processName support, remove
4283 _check_logger_class from multiprocessing.
4284
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004285- Issue #2975: When compiling several extension modules with Visual Studio 2008
4286 from the same python interpreter, some environment variables would grow
4287 without limit.
4288
Benjamin Peterson37346b22008-08-23 20:27:43 +00004289- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4290 exploitation of poor argument checking.
4291
Gerhard Häringef2276b2008-09-12 13:54:06 +00004292- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4293
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004294- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4295 remaining ones have "pysqlite_" prefix.
4296
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004297- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

4305 wrapper for warnings.catch_warnings() that makes it easier to check
4306 that expected warning messages are being reported.
4307
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00004308- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004326What's New in Python 2.6 beta 3?
4327================================
4328
Barry Warsaw07a4a382008-08-21 01:15:08 +00004329*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004330
4331Core and Builtins
4332-----------------
4333
Guido van Rossumf8402962008-08-20 15:01:50 +00004334- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4335 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4336 extensions do not automatically benefit from the class attribute
4337 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4338 to their tp_flags field if they care. This is a backwards
4339 compatibility feature; in 3.0, all types will use the cache by
4340 default.
4341
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004342- Keyword arguments can now follow starred arguments. (``f(a, *args,
4343 keyword=23)`` is now valid syntax.)
4344
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004345- ctypes function pointers that are COM methods have a boolean True
4346 value again.
4347
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004348- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4349 by denying s# to parse objects that have a releasebuffer procedure,
4350 and introducing s*.
4351
Georg Brandl1e13ea92008-08-11 09:07:59 +00004352- Issue #3537: Fix an assertion failure when an empty but presized dict
4353 object was stored in the freelist.
4354
Mark Dickinsonb6467572008-08-04 21:30:09 +00004355- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4356 ValueError consistently across platforms.
4357
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004358- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4359 (64bit Unix, for example), unichr() would truncate its argument and return
4360 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4361
Neal Norwitze7d8be82008-07-31 17:17:14 +00004362- Apply security patches from Apple.
4363
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004364- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4365 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4366
Antoine Pitrou92f82162008-07-25 22:22:08 +00004367- Issue #1819: function calls with several named parameters are now on
4368 average 35% faster (as measured by pybench).
4369
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004370- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4371 the python debugger steps into a class statement: the free variables (local
4372 variables defined in an outer scope) would be deleted from the outer scope.
4373
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004374- Issue #2620: Overflow checking when allocating or reallocating memory
4375 was not always being done properly in some python types and extension
4376 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4377 all been updated to perform better checks and places in the code that
4378 would previously leak memory on the error path when such an allocation
4379 failed have been fixed.
4380
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004381Library
4382-------
4383
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004384- Issue #3612: Added some missing basic types in ctypes.wintypes.
4385
Benjamin Petersone977ad42008-08-20 01:42:01 +00004386- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4387 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4388
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004389- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4390 version reported by these tools does not necessarily follow the python
4391 version numbering scheme, so the module is less strict when parsing it.
4392
Nick Coghlanf70385a2008-08-18 12:42:46 +00004393- Issue #2235: Added Py3k warnings for types which will become unhashable
4394 under the stricter __hash__ inheritance rules in 3.0. Several types
4395 which did not meet the rules for hash invariants and were already
4396 unhashable in 3.0 have now been explicitly flagged as unhashable in
4397 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4398 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4399
Brett Cannon88f801d2008-08-18 00:46:22 +00004400- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4401 imported into the module but exposed as part of the module's API.
4402
Brett Cannon7b96f072008-08-18 00:41:11 +00004403- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4404
Brett Cannon46225e72008-08-18 00:36:52 +00004405- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004407- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4408
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004409- Issue #3575: Incremental decoder's decode function now takes bytearray
4410 by using 's*' instead of 't#'.
4411
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004412- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004413 fails unicode conversion on 2nd parameter. (windows only)
4414
Georg Brandl222e2082010-08-01 22:27:39 +00004415- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004416 in a redirect.
4417
Brett Cannonabe423e2008-08-16 21:47:07 +00004418- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004419 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004420
Facundo Batistaeb90b782008-08-16 14:44:07 +00004421- Issue #2776: fixed small issue when handling an URL with double slash
4422 after a 302 response in the case of not going through a proxy.
4423
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004424- Issue #2676: in the email package, content-type parsing was hanging on
4425 pathological input because of quadratic or exponential behaviour of a
4426 regular expression.
4427
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004428- Issue #3476: binary buffered reading through the new "io" library is now
4429 thread-safe.
4430
Brett Cannonbf3157b2008-08-14 05:00:03 +00004431- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4432 since mimetools itself is deprecated. Because modules are cached, all
4433 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4434
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004435- Issue #3134: shutil referenced undefined WindowsError symbol.
4436
Robert Schuppenies14646332008-08-10 11:01:53 +00004437- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4438 menu entries were not deleted.
4439
Brett Cannon83e81842008-08-09 23:30:55 +00004440- Copied the implementation of reduce() to _functools.reduce() to have a
4441 version that did not raise a DeprecationWarning under -3.
4442
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004443- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4444 a MemoryError rather than silently stop the iteration.
4445
Guido van Rossum59ce9012008-08-09 14:55:34 +00004446- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4447 to _sre.compile() will now be rejected. This should not affect anybody
4448 since the re.compile() function never generates invalid re-bytecode.
4449
Skip Montanaroa032bf42008-08-08 22:52:51 +00004450- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4451 upon first access it can be automatically initialized from the csv file if
4452 it wasn't initialized during instantiation.
4453
Brett Cannon3aa2a492008-08-06 22:28:09 +00004454- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4455 the reload() built-in has been removed.
4456
Brett Cannon7e30b672008-08-04 21:52:25 +00004457- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004458 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004469 asking for a specific length. This problem only affected files opened
4470 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004471

4496 file name rather than a ZipInfo instance, so files are extracted with
4497 mode 0600 rather than 000 under Unix.
4498
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004499- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4500 argument in python 2.5, this broke code that subclassed Popen to include its
4501 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4516 regarding lack of coverage of new-style classes have also been
4517 removed, since the coverage is now fairly reasonable.

4527
Georg Brandl3e483f62008-07-16 22:57:41 +00004528- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4529 its methods now allow for items objects that can be converted to
4530 an integer using operator.index().
4531
Mark Dickinson64b7e502008-07-16 09:40:03 +00004532- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4533 produced a ValueError instead of giving the correct float.
4534
Eric Smitha5fa5a22008-07-16 00:11:49 +00004535- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4536 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4537
Mark Dickinson7103aa42008-07-15 19:08:33 +00004538- Issue #3008: the float type has a new instance method 'float.hex'
4539 and a new class method 'float.fromhex' to convert floating-point
4540 numbers to and from hexadecimal strings, respectively.
4541
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004542- Issue #2235: __hash__ is once again inherited by default. To allow
4543 collections.Hashable to remain meaningful in the presence of the
4544 default hash implementation (object.__hash__), it is now possible
4545 to explicit block inheritance of hash by setting __hash__=None at
4546 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4547 level.
4548
Nick Coghlanb028f502008-07-13 14:52:36 +00004549- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4550 the parent module cannot be found while performing an absolute import.
4551 This means that an incorrectly defined __package__ attribute will
4552 now only prevent relative imports in that module rather than causing
4553 all imports from that module to fail.
4554
Nick Coghlan14ff9942008-07-08 14:21:42 +00004555- Issue #2517: Allow unicode messages in Exceptions again by correctly

4566
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004567- Issue #3004: Minor change to slice.indices(): the start and stop
4568 arguments are now treated identically, making the behaviour easier
4569 to describe and understand. For example, slice(None, -10,
4570 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4571 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4572 10, -1).

4615 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004616 wrong because the actual transmitted size could differ from the

5089 original Python code has been kept as backup). This will allow for
5090 using the 'warning's machinery in such places as the parser where
5091 use of pure Python code is not possible. Both the ``showarning()``
5092 and ``formatwarning()`` gain an optional 'line' argument which is

Georg Brandl3ee81df2008-05-17 18:14:43 +00005158- Issue #2550: The approach used by client/server code for obtaining
5159 ports to listen on in network-oriented tests has been refined in an
5160 effort to facilitate running multiple instances of the entire
5161 regression test suite in parallel without issue.
5162 test_support.bind_port() has been fixed such that it will always
5163 return a unique port -- which wasn't always the case with the
5164 previous implementation, especially if socket options had been set
5165 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5166 new implementation of bind_port() will actually raise an exception
5167 if it is passed an AF_INET/SOCK_STREAM socket with either the
5168 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5169 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5170 the socket it's been passed. This currently only applies to
5171 Windows. This option prevents any other sockets from binding to the
5172 host/port we've bound to, thus removing the possibility of the
5173 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5174 when a second SOCK_STREAM socket binds and accepts to a host/port
5175 that's already been bound by another socket. The optional preferred
5176 port parameter to bind_port() has been removed. Under no
5177 circumstances should tests be hard coding ports!
5178
5179 test_support.find_unused_port() has also been introduced, which will
5180 pass a temporary socket object to bind_port() in order to obtain an
5181 unused port. The temporary socket object is then closed and
5182 deleted, and the port is returned. This method should only be used
5183 for obtaining an unused port in order to pass to an external program
5184 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5185 a parameter to a server-oriented class that doesn't give you direct
5186 access to the underlying socket used.
5187
5188 Finally, test_support.HOST has been introduced, which should be used
5189 for the host argument of any relevant socket calls (i.e. bind and
5190 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005191
5192 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005193 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005194 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5195 test_asynchat and test_socket_ssl.
5196
Georg Brandl3ee81df2008-05-17 18:14:43 +00005197 It is now possible for multiple instances of the regression test
5198 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005364- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
5365 values on 32-bit vs. 64-bit python interpreters. Both were correct,
5366 but they now both return a signed integer object for consistency.

Eric Smitha73fbe72008-02-23 03:09:44 +00005477- Added the future_builtins module, which contains hex() and oct().
5478 These are the PEP 3127 version of these functions, designed to be
5479 compatible with the hex() and oct() builtins from Python 3.0. They
5480 differ slightly in their output formats from the existing, unchanged
5481 Python 2.6 builtins. The expected usage of the future_builtins
5482 module is:
5483 from future_builtins import hex, oct
5484
Eric Smith7ef40bf2008-02-20 23:34:22 +00005485- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5486 exponents for exponents with absolute value < 100. Follows C99
5487 standard. This is a change on Windows, which would use 3 digits.
5488 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5489 so that any alterations it does to the resulting string will be
5490 available in stringlib/formatter.h (for float.__format__).
5491
Eric Smith5a3c1352008-02-19 13:21:56 +00005492- Implemented PEP 3101, Advanced String Formatting. This adds a new
5493 builtin format(); a format() method for str and unicode; a
5494 __format__() method to object, str, unicode, int, long, float, and
5495 datetime; the class string.Formatter; and the C API
5496 PyObject_Format().
5497
Georg Brandl3ee81df2008-05-17 18:14:43 +00005498- Fixed several potential crashes, all caused by specially crafted
5499 __del__ methods exploiting objects in temporarily inconsistent
5500 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005501
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005502- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005503 prevent a possible crash: an Abstract Base Class would try to access
5504 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005505

Georg Brandl3ee81df2008-05-17 18:14:43 +00005509- Clear all free lists during a gc.collect() of the highest generation
5510 in order to allow pymalloc to free more arenas. Python may give back
5511 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005512
Georg Brandl3ee81df2008-05-17 18:14:43 +00005513- Issue #2045: Fix an infinite recursion triggered when printing a
5514 subclass of collections.defaultdict, if its default_factory is set
5515 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005516
Christian Heimesf75dbef2008-02-08 00:11:31 +00005517- Fixed a minor memory leak in dictobject.c. The content of the free
5518 list was not freed on interpreter shutdown.
5519
Georg Brandl21e99f42010-03-07 15:23:59 +00005520- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005521 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005522
Georg Brandl3ee81df2008-05-17 18:14:43 +00005523- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5524 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005525 to compact the internal free lists of pre-allocted ints and floats.
5526
Georg Brandl3ee81df2008-05-17 18:14:43 +00005527- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5528 calls. Python expected the return type int but the fork familie
5529 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005530
Georg Brandl3ee81df2008-05-17 18:14:43 +00005531- Issue #1678380: Fix a bug that identifies 0j and -0j when they

5541 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005542
Georg Brandl3ee81df2008-05-17 18:14:43 +00005543- Patch #1473257: generator objects gain a gi_code attribute. This is
5544 the same object as the func_code attribute of the function that
5545 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005546
Georg Brandl3ee81df2008-05-17 18:14:43 +00005547- Issue #1920: "while 0" statements were completely removed by the
5548 compiler, even in the presence of an "else" clause, which is
5549 supposed to be run when the condition is false. Now the compiler
5550 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005551
Guido van Rossumeead05f2008-01-24 18:21:02 +00005552- A few crashers fixed: weakref_in_del.py (issue #1377858);
5553 loosing_dict_ref.py (issue #1303614, test67.py);
5554 borrowed_ref_[34].py (not in tracker).
5555
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005556- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005557 suppressed while an extension is loaded by calling SetErrorMode in

5559
Georg Brandl3ee81df2008-05-17 18:14:43 +00005560- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005561 several extension methods and modules do not work without unicode
5562 support.
5563
Georg Brandl26543b12008-01-21 18:36:51 +00005564- Issue #1882: when compiling code from a string, encoding cookies in the
5565 second line of code were not always recognized correctly.
5566
Georg Brandl14404b62008-01-19 19:27:05 +00005567- Issue #1679: "0x" was taken as a valid integer literal.
5568
Georg Brandl6caad7d2008-01-26 14:19:22 +00005569- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005570 added.
5571
Christian Heimesc94e2b52008-01-14 04:13:37 +00005572- sys.float_info / PyFloat_GetInfo: The floating point information
5573 object was converted from a dict to a specialized structseq object.
5574
Georg Brandl3ee81df2008-05-17 18:14:43 +00005575- Patch #1816: Added sys.flags structseq. It exposes the status of
5576 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005577
Georg Brandl3ee81df2008-05-17 18:14:43 +00005578- Objects/structseq.c: Implemented new structseq representation. The
5579 patch makes structseqs (e.g. the return value of os.stat) more
5580 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005581
Georg Brandl3ee81df2008-05-17 18:14:43 +00005582- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00005604 and INF. float("nan"), float("inf") and float("-inf") now work on
5605 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005607- Compiler now generates simpler and faster code for dictionary
5608 literals. The oparg for BUILD_MAP now indicates an estimated
5609 dictionary size. There is a new opcode, STORE_MAP, for adding
5610 entries to the dictionary.

5622
Nick Coghlanef01d822007-12-03 12:55:17 +00005623- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005639- Patch #1739468: Directories and zipfiles containing a __main__.py
5640 file can now be directly executed by passing their name to the
5641 interpreter. The directory/zipfile is automatically inserted as the
5642 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005643
Georg Brandl3ee81df2008-05-17 18:14:43 +00005644- Issue #1265: Fix a problem with sys.settrace, if the tracing
5645 function uses a generator expression when at the same time the
5646 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005647
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005648- sets and frozensets now have an isdisjoint() method.

5653
Georg Brandl21e99f42010-03-07 15:23:59 +00005654- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005655 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5656 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005657
Georg Brandl3ee81df2008-05-17 18:14:43 +00005658- Issue #1686386: Tuple's tp_repr did not take into account the
5659 possibility of having a self-referential tuple, which is possible
5660 from C code. Nor did object's tp_str consider that a type's tp_str
5661 could do something that could lead to an inifinite recursion.
5662 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5663 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005664
Georg Brandl3ee81df2008-05-17 18:14:43 +00005665- Issue #1164: It was possible to trigger deadlock when using the
5666 'print' statement to write to a file since the GIL was not released
5667 as needed. Now PyObject_Print() does the right thing along with
5668 various tp_print implementations of the built-in types and those in
5669 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005670
Georg Brandl3ee81df2008-05-17 18:14:43 +00005671- Issue #1147: Exceptions were directly allowing string exceptions in
5672 their throw() method even though string exceptions no longer
5673 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005674
Georg Brandl3ee81df2008-05-17 18:14:43 +00005675- Issue #1096: Prevent a segfault from getting the repr of a very
5676 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005677
Brett Cannon1e534b52007-09-07 04:18:30 +00005678- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005679 PyObject_Call() never calling back out to Python code to trigger
5680 recursion depth updates/checks. Required the creation of a static
5681 RuntimeError instance in case normalizing an exception put the
5682 recursion check value past its limit. Fixes crashers
5683 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005684
Georg Brandl3ee81df2008-05-17 18:14:43 +00005685- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005698- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005699 __*__ attributes. (Some already existed, e.g., __doc__ and
5700 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005701
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005702- Add -3 option to the interpreter to warn about features that are
5703 deprecated and will be changed/removed in Python 3.0.
5704
Georg Brandl2134e752007-05-21 20:34:16 +00005705- Patch #1686487: you can now pass any mapping after '**' in function
5706 calls.
5707
Collin Winter62903052007-05-18 23:11:24 +00005708- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005709 "except E as target:". This is to provide forwards compatibility
5710 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005711
Brett Cannon229cee22007-05-05 01:34:02 +00005712- Deprecate BaseException.message as per PEP 352.
5713
Georg Brandl3ee81df2008-05-17 18:14:43 +00005714- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005715 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005716
Vinay Sajip8549ce32007-05-06 17:53:37 +00005717- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005718 setting a plain string, ie don't expand to single letter identifiers.
5719
Raymond Hettinger13936692007-04-11 18:40:58 +00005720- Request #1191699: Slices can now be pickled.
5721
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005722- Request #1193128: str.translate() now allows a None argument for
5723 translations that only remove characters without re-mapping the
5724 remaining characters.
5725
Georg Brandl5cb76c12007-03-21 09:00:39 +00005726- Patch #1682205: a TypeError while unpacking an iterable is no longer
5727 masked by a generic one with the message "unpack non-sequence".
5728
Neal Norwitzaa754b72007-03-21 06:39:48 +00005729- Remove unused file Python/fmod.c.
5730
Guido van Rossum143b5642007-03-23 04:58:42 +00005731- Bug #1683368: The object.__init__() and object.__new__() methods are
5732 now stricter in rejecting excess arguments. The only time when
5733 either allows excess arguments is when it is not overridden and the
5734 other one is. For backwards compatibility, when both are
5735 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005736 warning later). Also, type.__init__() insists on the same signature
5737 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005738
Georg Brandl3ee81df2008-05-17 18:14:43 +00005739- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5740 object to complex using its __complex__() method before falling back
5741 to the __float__() method. Therefore, the functions in the cmath
5742 module now can operate on objects that define a __complex__()
5743 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005744
Georg Brandl3ee81df2008-05-17 18:14:43 +00005745- Patch #1623563: allow __class__ assignment for classes with
5746 __slots__. The old and the new class are still required to have the
5747 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005748
Georg Brandl3ee81df2008-05-17 18:14:43 +00005749- Patch #1642547: Fix an error/crash when encountering syntax errors

5753 ``object.__reduce_ex__()`` is called with an object that is faking
5754 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005755
Georg Brandl3ee81df2008-05-17 18:14:43 +00005756- Patch #1680015: Don't modify __slots__ tuple if it contains an

5760
Georg Brandl7b9c5552007-03-12 14:30:05 +00005761- Bug #1678647: write a newline after printing an exception in any
5762 case, even when converting the value to a string failed.
5763
Georg Brandl871f1bc2007-03-12 13:17:36 +00005764- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005765 its argument, if it exists. If not, it will work like before. This
5766 allows customizing the output of dir() in the presence of a
5767 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005768
Collin Winter276887b2007-03-12 16:11:39 +00005769- Patch #922167: Python no longer segfaults when faced with infinitely
5770 self-recursive reload() calls (as reported by bug #742342).
5771
Georg Brandl3ee81df2008-05-17 18:14:43 +00005772- Patch #1675981: remove unreachable code from ``type.__new__()``
5773 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005775- Patch #1491866: change the complex() constructor to allow
5776 parthensized forms. This means complex(repr(x)) now works instead of
5777 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005778
Georg Brandlaa2321b2007-03-07 00:40:28 +00005779- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005780 makes the filenames the warning module prints much more sensible
5781 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005782
Georg Brandl49aafc92007-03-07 00:34:46 +00005783- Variant of patch #697613: don't exit the interpreter on a SystemExit
5784 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005785 variable is given, but break into the interactive interpreter just
5786 like on other exceptions or normal program exit.

5792 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005793
Georg Brandl0fca97a2007-03-05 22:28:08 +00005794- Patch #1674228: when assigning a slice (old-style), check for the
5795 sq_ass_slice instead of the sq_slice slot.
5796
Georg Brandl3ee81df2008-05-17 18:14:43 +00005797- When printing an unraisable error, don't print exceptions. before
5798 the name. This duplicates the behavior whening normally printing
5799 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006350- Patch #1530482: add pydoc.render_doc() which returns the

6365
Georg Brandl92a6bae2007-03-13 17:43:32 +00006366- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006367 are set for invalid interpolation sequences that would lead to
6368 errors on reading back those values.

6422
Georg Brandl3ee81df2008-05-17 18:14:43 +00006423- unittest now verifies more of its assumptions. In particular,
6424 TestCase and TestSuite subclasses (not instances) are no longer
6425 accepted in TestSuite.addTest(). This should cause no
6426 incompatibility since it never made sense with ordinary subclasses
6427 -- the failure just occurred later, with a more cumbersome
6428 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006715 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00006717 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006816- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006817 time so that opening a database previously created with the DB_DUP
6818 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6819 opens. Specifically: dictionary assignment to a DB object will
6820 replace all values for a given key when the database allows
6821 duplicate values. DB users should use DB.put(k, v) when they want
6822 to store duplicates; not DB[k] = v.

6831 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007101- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007102 periodic threadstate and signal checking in tight loops. By
7103 default, this option is turned-off. It should only be enabled in

Georg Brandl3ee81df2008-05-17 18:14:43 +00007162- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7163 to ``PyTuple_SetItem``, it can be used to populate a brand new

7176
Georg Brandl3ee81df2008-05-17 18:14:43 +00007177- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7178 of w# format code incorrectly truncated the length to an int, even
7179 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7180 incorrect results with huge strings.

7208 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007209
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7211 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007212
Georg Brandl3ee81df2008-05-17 18:14:43 +00007213- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
