Ezio Melottiab2eb0e2010-06-05 19:21:32 +000092- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
93 start byte and the continuation byte(s) are now considered invalid, instead
94 of the number of bytes specified by the start byte.
95 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
96 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
97 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
98 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000100- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000101 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
102 arises from the "Overriding __eq__ blocks inheritance ..." warning
103 when turned into an exception: in this case the exception simply
104 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000106- Issue #8748: Fix two issues with comparisons between complex and integer
107 objects. (1) The comparison could incorrectly return True in some cases
108 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
109 (2) The comparison raised an OverflowError for large integers, leading
110 to unpredictable exceptions when combining integers and complex objects
111 in sets or dicts.
112
Mark Dickinson81336372010-05-30 12:12:25 +0000113- Issue #5211: Implicit coercion for the complex type is now completely
114 removed. (Coercion for arithmetic operations was already removed in 2.7
115 alpha 4, but coercion for rich comparisons was accidentally left in.)
116
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000117- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

494 with a non-empty format string. This is an effort to future-proof user
495 code. If a derived class does not currently implement __format__ but later
496 adds its own __format__, it would most likely break user code that had
497 supplied a format string. This will be changed to a DeprecationWaring in
498 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +0000531- Issue #8257: The Decimal construct now accepts a float instance directly,
532 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000533
534 >>> Decimal(1.1)
535 Decimal('1.100000000000000088817841970012523233890533447265625')
536
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000537- collections.Counter() now supports a subtract() method.
538
Georg Brandlfee0f442010-05-22 21:26:21 +0000539- The functools module now has a total_ordering() class decorator to simplify
540 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +0000548- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
549 InvalidOperation instead of returning False. (Comparisons involving a quiet
550 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
551 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +0000553- Issue #2531: Comparison operations between floats and Decimal instances now
554 return a result based on the numeric values of the operands; previously they
555 returned an arbitrary result based on the relative ordering of id(float) and
556 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000557
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000558- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000559 argument `-` which tells it to read files to compile from stdin. Each line is
560 read on demand and the named file is compiled immediately. (Original patch by
561 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000570- Comparisons using one of <, <=, >, >= between a complex instance and a
571 Fractions instance now raise TypeError instead of returning True/False. This
572 makes Fraction <=> complex comparisons consistent with int <=> complex, float
573 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +0000677- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
678 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +0000680 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
681 inconsistent: __int__ was used for some integer codes but not for others, and
682 the set of integer codes for which it was used differed between native packing
683 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000981 file position when calling `truncate()`. It would previously change the file
982 position to the given argument, which goes against the tradition of

986 class used to represent files stored inside an archive. The new
987 implementation is significantly faster and can be wrapped in a
988 ``io.BufferedReader`` object for more speedups. It also solves an issue
989 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1085
Mark Dickinson1b34d252010-01-01 17:27:30 +00001086- Issue #5080: A number of functions and methods previously produced a

1088 These functions and methods now raise TypeError instead. The majority of the
1089 effects of this change are in the extension modules, but some core functions
1090 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1091 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00001256- Issue #3382: 'F' formatting for float and complex now convert the result to
1257 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1258 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001259
Georg Brandlba83f822010-03-14 09:50:54 +00001260- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1261 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001262
Georg Brandlba83f822010-03-14 09:50:54 +00001263- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1264 1e-100 used to raise OverflowError, but now gives the requested 120
1265 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001266

1272 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001273
Georg Brandlba83f822010-03-14 09:50:54 +00001274- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1275 decimal string that's guaranteed to round back to x under correct rounding
1276 (with round-half-to-even rounding mode). Previously it gave a string based on
1277 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1278 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1279 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001280
Georg Brandlba83f822010-03-14 09:50:54 +00001281- Issue #7117: On almost all platforms: float-to-string and string-to-float
1282 conversions within Python are now correctly rounded. Places these conversions
1283 occur include: str for floats and complex numbers; the float and complex
1284 constructors; old-style and new-style numeric formatting; serialization and
1285 deserialization of floats and complex numbers using marshal, pickle and json;
1286 parsing of float and imaginary literals in Python code; Decimal-to-float
1287 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001288
Georg Brandlba83f822010-03-14 09:50:54 +00001289 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1290 providing correctly-rounded strtod and dtoa C functions. This code is
1291 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1292 the C compiler. There may be a small number of platforms on which correct
1293 operation of this code cannot be guaranteed, so the code is not used: notably,
1294 this applies to platforms where the C double format is not IEEE 754 binary64,
1295 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1296 and Python's configure script is unable to determine how to change the FPU
1297 precision. On these platforms conversions use the platform strtod and dtoa,
1298 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001300- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1301 uses the correctly-rounded string <-> float conversions described above (when
1302 available), and so produces correctly rounded results that will display nicely
1303 under the float repr. There are two related small changes: (1) round now
1304 accepts any class with an ``__index__()`` method for its second argument (but
1305 no longer accepts floats for the second argument), and (2) an excessively
1306 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1307 raises an exception.

1310
Georg Brandlba83f822010-03-14 09:50:54 +00001311- Fix several issues with ``compile()``. The input can now contain Windows and
1312 Mac newlines and is no longer required to end in a newline.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003112 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003113 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003115- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003116 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3117 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3118 when given a tuple of classes as second argument, were looking up
3119 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3120 type object.
3121
Neal Norwitz18aa3882008-08-24 05:04:52 +00003122- Fix crashes on memory allocation failure found with failmalloc.

3191 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3192 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003259What's New in Python 2.6 beta 3?
3260================================
3261
Barry Warsaw07a4a382008-08-21 01:15:08 +00003262*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003263
3264Core and Builtins
3265-----------------
3266
Guido van Rossumf8402962008-08-20 15:01:50 +00003267- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3268 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3269 extensions do not automatically benefit from the class attribute
3270 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3271 to their tp_flags field if they care. This is a backwards
3272 compatibility feature; in 3.0, all types will use the cache by
3273 default.
3274
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003275- Keyword arguments can now follow starred arguments. (``f(a, *args,
3276 keyword=23)`` is now valid syntax.)
3277
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003278- ctypes function pointers that are COM methods have a boolean True
3279 value again.
3280
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003281- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3282 by denying s# to parse objects that have a releasebuffer procedure,
3283 and introducing s*.
3284
Georg Brandl1e13ea92008-08-11 09:07:59 +00003285- Issue #3537: Fix an assertion failure when an empty but presized dict
3286 object was stored in the freelist.
3287
Mark Dickinsonb6467572008-08-04 21:30:09 +00003288- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3289 ValueError consistently across platforms.
3290
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003291- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3292 (64bit Unix, for example), unichr() would truncate its argument and return
3293 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3294
Neal Norwitze7d8be82008-07-31 17:17:14 +00003295- Apply security patches from Apple.
3296
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003297- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3298 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3299
Antoine Pitrou92f82162008-07-25 22:22:08 +00003300- Issue #1819: function calls with several named parameters are now on
3301 average 35% faster (as measured by pybench).
3302
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003303- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3304 the python debugger steps into a class statement: the free variables (local
3305 variables defined in an outer scope) would be deleted from the outer scope.
3306
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003307- Issue #2620: Overflow checking when allocating or reallocating memory
3308 was not always being done properly in some python types and extension
3309 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3310 all been updated to perform better checks and places in the code that
3311 would previously leak memory on the error path when such an allocation
3312 failed have been fixed.

3316
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003317- Issue #3612: Added some missing basic types in ctypes.wintypes.
3318
Benjamin Petersone977ad42008-08-20 01:42:01 +00003319- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3320 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3321
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003322- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3323 version reported by these tools does not necessarily follow the python
3324 version numbering scheme, so the module is less strict when parsing it.
3325
Nick Coghlanf70385a2008-08-18 12:42:46 +00003326- Issue #2235: Added Py3k warnings for types which will become unhashable
3327 under the stricter __hash__ inheritance rules in 3.0. Several types
3328 which did not meet the rules for hash invariants and were already
3329 unhashable in 3.0 have now been explicitly flagged as unhashable in
3330 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3331 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3332
Brett Cannon88f801d2008-08-18 00:46:22 +00003333- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3334 imported into the module but exposed as part of the module's API.
3335
Brett Cannon7b96f072008-08-18 00:41:11 +00003336- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3337
Brett Cannon46225e72008-08-18 00:36:52 +00003338- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003340- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3341
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003342- Issue #3575: Incremental decoder's decode function now takes bytearray
3343 by using 's*' instead of 't#'.
3344
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003345- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003346 fails unicode conversion on 2nd parameter. (windows only)
3347
Facundo Batista94f243a2008-08-17 03:38:39 +00003348- Issue 2464. urllib2 now supports a malformation in the URL received
3349 in a redirect.
3350
Brett Cannonabe423e2008-08-16 21:47:07 +00003351- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003352 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003353
Facundo Batistaeb90b782008-08-16 14:44:07 +00003354- Issue #2776: fixed small issue when handling an URL with double slash
3355 after a 302 response in the case of not going through a proxy.
3356
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003357- Issue #2676: in the email package, content-type parsing was hanging on
3358 pathological input because of quadratic or exponential behaviour of a
3359 regular expression.
3360
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003361- Issue #3476: binary buffered reading through the new "io" library is now
3362 thread-safe.
3363
Brett Cannonbf3157b2008-08-14 05:00:03 +00003364- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3365 since mimetools itself is deprecated. Because modules are cached, all
3366 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3367
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003368- Issue #3134: shutil referenced undefined WindowsError symbol.
3369
Robert Schuppenies14646332008-08-10 11:01:53 +00003370- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3371 menu entries were not deleted.
3372
Brett Cannon83e81842008-08-09 23:30:55 +00003373- Copied the implementation of reduce() to _functools.reduce() to have a
3374 version that did not raise a DeprecationWarning under -3.
3375
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003376- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3377 a MemoryError rather than silently stop the iteration.
3378
Guido van Rossum59ce9012008-08-09 14:55:34 +00003379- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3380 to _sre.compile() will now be rejected. This should not affect anybody
3381 since the re.compile() function never generates invalid re-bytecode.
3382
Skip Montanaroa032bf42008-08-08 22:52:51 +00003383- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3384 upon first access it can be automatically initialized from the csv file if
3385 it wasn't initialized during instantiation.
3386
Brett Cannon3aa2a492008-08-06 22:28:09 +00003387- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3388 the reload() built-in has been removed.
3389
Brett Cannon7e30b672008-08-04 21:52:25 +00003390- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003391 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003402 asking for a specific length. This problem only affected files opened

3459-----------------
3460
Georg Brandl3e483f62008-07-16 22:57:41 +00003461- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3462 its methods now allow for items objects that can be converted to
3463 an integer using operator.index().
3464
Mark Dickinson64b7e502008-07-16 09:40:03 +00003465- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3466 produced a ValueError instead of giving the correct float.
3467
Eric Smitha5fa5a22008-07-16 00:11:49 +00003468- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3469 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3470
Mark Dickinson7103aa42008-07-15 19:08:33 +00003471- Issue #3008: the float type has a new instance method 'float.hex'
3472 and a new class method 'float.fromhex' to convert floating-point
3473 numbers to and from hexadecimal strings, respectively.
3474
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003475- Issue #2235: __hash__ is once again inherited by default. To allow
3476 collections.Hashable to remain meaningful in the presence of the
3477 default hash implementation (object.__hash__), it is now possible
3478 to explicit block inheritance of hash by setting __hash__=None at
3479 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3480 level.
3481
Nick Coghlanb028f502008-07-13 14:52:36 +00003482- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3483 the parent module cannot be found while performing an absolute import.
3484 This means that an incorrectly defined __package__ attribute will
3485 now only prevent relative imports in that module rather than causing
3486 all imports from that module to fail.
3487
Nick Coghlan14ff9942008-07-08 14:21:42 +00003488- Issue #2517: Allow unicode messages in Exceptions again by correctly

3498 another thread's dictionary.
3499
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003500- Issue #3004: Minor change to slice.indices(): the start and stop
3501 arguments are now treated identically, making the behaviour easier
3502 to describe and understand. For example, slice(None, -10,
3503 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3504 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3505 10, -1).
3506
Georg Brandl278fc502008-07-19 12:46:12 +00003507- Issue #3219: Calling a function with repeated keyword arguments,
3508 f(a=2, a=23), would not cause a syntax error. This was a regression
3509 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003547- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3548 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003549 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003550 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003566- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3976
Georg Brandl74a1dea2008-05-28 11:21:39 +00003977- Add ``PyType_Modified()`` as a public API to clear the type cache.
3978
3979- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003980
3981- The PyString functions have been renamed to PyBytes. A batch of
3982 defines were added so that the linker still sees the original
3983 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004021- Issue #1631171: Re-implement the 'warnings' module in C (the
4022 original Python code has been kept as backup). This will allow for
4023 using the 'warning's machinery in such places as the parser where
4024 use of pure Python code is not possible. Both the ``showarning()``
4025 and ``formatwarning()`` gain an optional 'line' argument which is
4026 not called by default for backwards-compatibility reasons. Setting
4027 ``warnings.showwarning()`` to an implementation that lacks support
4028 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004070- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004071 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004091- Issue #2550: The approach used by client/server code for obtaining
4092 ports to listen on in network-oriented tests has been refined in an
4093 effort to facilitate running multiple instances of the entire
4094 regression test suite in parallel without issue.
4095 test_support.bind_port() has been fixed such that it will always
4096 return a unique port -- which wasn't always the case with the
4097 previous implementation, especially if socket options had been set
4098 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4099 new implementation of bind_port() will actually raise an exception
4100 if it is passed an AF_INET/SOCK_STREAM socket with either the
4101 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4102 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4103 the socket it's been passed. This currently only applies to
4104 Windows. This option prevents any other sockets from binding to the
4105 host/port we've bound to, thus removing the possibility of the
4106 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4107 when a second SOCK_STREAM socket binds and accepts to a host/port
4108 that's already been bound by another socket. The optional preferred
4109 port parameter to bind_port() has been removed. Under no
4110 circumstances should tests be hard coding ports!
4111
4112 test_support.find_unused_port() has also been introduced, which will
4113 pass a temporary socket object to bind_port() in order to obtain an
4114 unused port. The temporary socket object is then closed and
4115 deleted, and the port is returned. This method should only be used
4116 for obtaining an unused port in order to pass to an external program
4117 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4118 a parameter to a server-oriented class that doesn't give you direct
4119 access to the underlying socket used.
4120
4121 Finally, test_support.HOST has been introduced, which should be used
4122 for the host argument of any relevant socket calls (i.e. bind and
4123 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004124
4125 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004126 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004127 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4128 test_asynchat and test_socket_ssl.
4129
Georg Brandl3ee81df2008-05-17 18:14:43 +00004130 It is now possible for multiple instances of the regression test
4131 suite to run in parallel without issue.

4398-----------------
4399
Fred Drakea8ee94b2008-03-01 02:45:07 +00004400- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004401 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004403- Issue #2067: file.__exit__() now calls subclasses' close() method.
4404
4405- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004406
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004407- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004408 issue 215555 for a discussion.
4409
Eric Smitha73fbe72008-02-23 03:09:44 +00004410- Added the future_builtins module, which contains hex() and oct().
4411 These are the PEP 3127 version of these functions, designed to be
4412 compatible with the hex() and oct() builtins from Python 3.0. They
4413 differ slightly in their output formats from the existing, unchanged
4414 Python 2.6 builtins. The expected usage of the future_builtins
4415 module is:
4416 from future_builtins import hex, oct
4417
Eric Smith7ef40bf2008-02-20 23:34:22 +00004418- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4419 exponents for exponents with absolute value < 100. Follows C99
4420 standard. This is a change on Windows, which would use 3 digits.
4421 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4422 so that any alterations it does to the resulting string will be
4423 available in stringlib/formatter.h (for float.__format__).
4424
Eric Smith5a3c1352008-02-19 13:21:56 +00004425- Implemented PEP 3101, Advanced String Formatting. This adds a new
4426 builtin format(); a format() method for str and unicode; a
4427 __format__() method to object, str, unicode, int, long, float, and
4428 datetime; the class string.Formatter; and the C API
4429 PyObject_Format().
4430
Georg Brandl3ee81df2008-05-17 18:14:43 +00004431- Fixed several potential crashes, all caused by specially crafted
4432 __del__ methods exploiting objects in temporarily inconsistent
4433 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004434
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004435- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004436 prevent a possible crash: an Abstract Base Class would try to access
4437 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004438

Georg Brandl3ee81df2008-05-17 18:14:43 +00004442- Clear all free lists during a gc.collect() of the highest generation
4443 in order to allow pymalloc to free more arenas. Python may give back
4444 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004445
Georg Brandl3ee81df2008-05-17 18:14:43 +00004446- Issue #2045: Fix an infinite recursion triggered when printing a
4447 subclass of collections.defaultdict, if its default_factory is set
4448 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004449
Christian Heimesf75dbef2008-02-08 00:11:31 +00004450- Fixed a minor memory leak in dictobject.c. The content of the free
4451 list was not freed on interpreter shutdown.
4452
Georg Brandl21e99f42010-03-07 15:23:59 +00004453- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004454 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004455
Georg Brandl3ee81df2008-05-17 18:14:43 +00004456- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4457 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004458 to compact the internal free lists of pre-allocted ints and floats.
4459
Georg Brandl3ee81df2008-05-17 18:14:43 +00004460- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4461 calls. Python expected the return type int but the fork familie
4462 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004463

4474 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004475
Georg Brandl3ee81df2008-05-17 18:14:43 +00004476- Patch #1473257: generator objects gain a gi_code attribute. This is
4477 the same object as the func_code attribute of the function that
4478 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004479
Georg Brandl3ee81df2008-05-17 18:14:43 +00004480- Issue #1920: "while 0" statements were completely removed by the
4481 compiler, even in the presence of an "else" clause, which is

4483 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00004485- A few crashers fixed: weakref_in_del.py (issue #1377858);
4486 loosing_dict_ref.py (issue #1303614, test67.py);
4487 borrowed_ref_[34].py (not in tracker).
4488
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004489- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004490 suppressed while an extension is loaded by calling SetErrorMode in
4491 dynload_win.c. The error is still reported properly.
4492
Georg Brandl3ee81df2008-05-17 18:14:43 +00004493- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004494 several extension methods and modules do not work without unicode
4495 support.
4496
Georg Brandl26543b12008-01-21 18:36:51 +00004497- Issue #1882: when compiling code from a string, encoding cookies in the
4498 second line of code were not always recognized correctly.
4499
Georg Brandl14404b62008-01-19 19:27:05 +00004500- Issue #1679: "0x" was taken as a valid integer literal.
4501
Georg Brandl6caad7d2008-01-26 14:19:22 +00004502- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004503 added.
4504
Christian Heimesc94e2b52008-01-14 04:13:37 +00004505- sys.float_info / PyFloat_GetInfo: The floating point information
4506 object was converted from a dict to a specialized structseq object.
4507
Georg Brandl3ee81df2008-05-17 18:14:43 +00004508- Patch #1816: Added sys.flags structseq. It exposes the status of
4509 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004510
Georg Brandl3ee81df2008-05-17 18:14:43 +00004511- Objects/structseq.c: Implemented new structseq representation. The
4512 patch makes structseqs (e.g. the return value of os.stat) more
4513 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004514
Georg Brandl3ee81df2008-05-17 18:14:43 +00004515- Patch #1700288: added a type attribute cache that caches method
4516 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004517
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004518- Bug #1776: __import__() no longer accepts filenames on any platform.
4519 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004520
Georg Brandlaed6c662008-01-07 17:25:53 +00004521- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4522
Georg Brandl3ee81df2008-05-17 18:14:43 +00004523- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4524 envvar and sys.dont_write_bytecode attribute. All these can be set
4525 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004526
Georg Brandl3ee81df2008-05-17 18:14:43 +00004527- Improve some exception messages when Windows fails to load an
4528 extension module. Now we get for example '%1 is not a valid Win32
4529 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004530

Georg Brandl3ee81df2008-05-17 18:14:43 +00004533- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4534 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004535
Christian Heimes0a8143f2007-12-18 23:22:54 +00004536- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004537 and INF. float("nan"), float("inf") and float("-inf") now work on
4538 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004539
Georg Brandl3ee81df2008-05-17 18:14:43 +00004540- Compiler now generates simpler and faster code for dictionary
4541 literals. The oparg for BUILD_MAP now indicates an estimated
4542 dictionary size. There is a new opcode, STORE_MAP, for adding
4543 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004572- Patch #1739468: Directories and zipfiles containing a __main__.py
4573 file can now be directly executed by passing their name to the
4574 interpreter. The directory/zipfile is automatically inserted as the
4575 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004576
Georg Brandl3ee81df2008-05-17 18:14:43 +00004577- Issue #1265: Fix a problem with sys.settrace, if the tracing
4578 function uses a generator expression when at the same time the
4579 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004580
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004581- sets and frozensets now have an isdisjoint() method.
4582
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004583- optimize the performance of builtin.sum().
4584
Neal Norwitz44f326e2007-10-05 05:29:17 +00004585- Fix warnings found by the new version of the Coverity checker.
4586
Georg Brandl21e99f42010-03-07 15:23:59 +00004587- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004588 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4589 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004590
Georg Brandl3ee81df2008-05-17 18:14:43 +00004591- Issue #1686386: Tuple's tp_repr did not take into account the
4592 possibility of having a self-referential tuple, which is possible
4593 from C code. Nor did object's tp_str consider that a type's tp_str
4594 could do something that could lead to an inifinite recursion.
4595 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4596 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004597
Georg Brandl3ee81df2008-05-17 18:14:43 +00004598- Issue #1164: It was possible to trigger deadlock when using the
4599 'print' statement to write to a file since the GIL was not released
4600 as needed. Now PyObject_Print() does the right thing along with
4601 various tp_print implementations of the built-in types and those in
4602 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004603
Georg Brandl3ee81df2008-05-17 18:14:43 +00004604- Issue #1147: Exceptions were directly allowing string exceptions in
4605 their throw() method even though string exceptions no longer
4606 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004607
Georg Brandl3ee81df2008-05-17 18:14:43 +00004608- Issue #1096: Prevent a segfault from getting the repr of a very
4609 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004610
Brett Cannon1e534b52007-09-07 04:18:30 +00004611- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004612 PyObject_Call() never calling back out to Python code to trigger
4613 recursion depth updates/checks. Required the creation of a static
4614 RuntimeError instance in case normalizing an exception put the
4615 recursion check value past its limit. Fixes crashers
4616 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004617

Neal Norwitz0ac60192007-05-27 04:08:54 +00004631- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004632 __*__ attributes. (Some already existed, e.g., __doc__ and
4633 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004634
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004635- Add -3 option to the interpreter to warn about features that are
4636 deprecated and will be changed/removed in Python 3.0.
4637
Georg Brandl2134e752007-05-21 20:34:16 +00004638- Patch #1686487: you can now pass any mapping after '**' in function
4639 calls.
4640
Collin Winter62903052007-05-18 23:11:24 +00004641- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004642 "except E as target:". This is to provide forwards compatibility
4643 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004644
Brett Cannon229cee22007-05-05 01:34:02 +00004645- Deprecate BaseException.message as per PEP 352.
4646
Georg Brandl3ee81df2008-05-17 18:14:43 +00004647- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004648 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004649
Vinay Sajip8549ce32007-05-06 17:53:37 +00004650- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004651 setting a plain string, ie don't expand to single letter identifiers.
4652
Raymond Hettinger13936692007-04-11 18:40:58 +00004653- Request #1191699: Slices can now be pickled.
4654
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004655- Request #1193128: str.translate() now allows a None argument for
4656 translations that only remove characters without re-mapping the
4657 remaining characters.
4658
Georg Brandl5cb76c12007-03-21 09:00:39 +00004659- Patch #1682205: a TypeError while unpacking an iterable is no longer
4660 masked by a generic one with the message "unpack non-sequence".
4661
Neal Norwitzaa754b72007-03-21 06:39:48 +00004662- Remove unused file Python/fmod.c.
4663
Guido van Rossum143b5642007-03-23 04:58:42 +00004664- Bug #1683368: The object.__init__() and object.__new__() methods are
4665 now stricter in rejecting excess arguments. The only time when
4666 either allows excess arguments is when it is not overridden and the
4667 other one is. For backwards compatibility, when both are
4668 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004669 warning later). Also, type.__init__() insists on the same signature
4670 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004671
Georg Brandl3ee81df2008-05-17 18:14:43 +00004672- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4673 object to complex using its __complex__() method before falling back
4674 to the __float__() method. Therefore, the functions in the cmath
4675 module now can operate on objects that define a __complex__()
4676 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004677
Georg Brandl3ee81df2008-05-17 18:14:43 +00004678- Patch #1623563: allow __class__ assignment for classes with
4679 __slots__. The old and the new class are still required to have the
4680 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004681

Georg Brandl3ee81df2008-05-17 18:14:43 +00004685- Patch #1462488: Python no longer segfaults when
4686 ``object.__reduce_ex__()`` is called with an object that is faking
4687 its type.

4693
Georg Brandl7b9c5552007-03-12 14:30:05 +00004694- Bug #1678647: write a newline after printing an exception in any
4695 case, even when converting the value to a string failed.
4696
Georg Brandl871f1bc2007-03-12 13:17:36 +00004697- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004698 its argument, if it exists. If not, it will work like before. This
4699 allows customizing the output of dir() in the presence of a
4700 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004702- Patch #922167: Python no longer segfaults when faced with infinitely
4703 self-recursive reload() calls (as reported by bug #742342).
4704
Georg Brandl3ee81df2008-05-17 18:14:43 +00004705- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004708- Patch #1491866: change the complex() constructor to allow
4709 parthensized forms. This means complex(repr(x)) now works instead of
4710 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004711
Georg Brandlaa2321b2007-03-07 00:40:28 +00004712- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004713 makes the filenames the warning module prints much more sensible
4714 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004715
Georg Brandl49aafc92007-03-07 00:34:46 +00004716- Variant of patch #697613: don't exit the interpreter on a SystemExit
4717 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004718 variable is given, but break into the interactive interpreter just
4719 like on other exceptions or normal program exit.

5221 ".cpp" too.
5222
Facundo Batistad918a652007-04-24 13:54:38 +00005223- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005224 the client's request was successfully received, understood, and
5225 accepted. Now in these cases no error is raised in urllib (issue
5226 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00005227

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005234- Added a timeout parameter to the constructor of other protocols
5235 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5236 work started with create_connection() and timeout in httplib, and
5237 closes patch #723312.
5238
Vinay Sajip8549ce32007-05-06 17:53:37 +00005239- Patch #1676823: Added create_connection() to socket.py, which may be
5240 called with a timeout, and use it from httplib (whose HTTPConnection

Facundo Batista07c78be2007-03-23 18:54:07 +00005242
Martin v. Löwis0af33882007-03-23 13:27:15 +00005243- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005250- Patch #1273829: os.walk() now has a "followlinks" parameter. If set

5263
Georg Brandlf66b6032007-03-14 08:27:52 +00005264- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005265 AttributeError instead of an IOError when the server's response
5266 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005267
Georg Brandl3ee81df2008-05-17 18:14:43 +00005268- Patch #957650: "%var%" environment variable references are now
5269 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00005272- Patch #1429539: pdb now correctly initializes the __main__ module
5273 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005274 correctly now.
5275
Georg Brandlbad6f192007-03-13 21:32:56 +00005276- The nonobvious commands.getstatus() function is now deprecated.

5282
Georg Brandl3ee81df2008-05-17 18:14:43 +00005283- Patch #1530482: add pydoc.render_doc() which returns the
5284 documentation for a thing instead of paging it to stdout, which
5285 pydoc.doc() does.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005287- Patch #1533909: the timeit module now accepts callables in addition

5293 parameter which can be set to False to prevent the default
5294 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00005295
Georg Brandl9e6b4702007-03-13 18:15:41 +00005296- Patch #1581073: add a flag to textwrap that prevents the dropping of
5297 whitespace while wrapping.
5298
Georg Brandl92a6bae2007-03-13 17:43:32 +00005299- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005300 are set for invalid interpolation sequences that would lead to
5301 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00005302

5344 returned string up to the first NUL character.

5355
Georg Brandl3ee81df2008-05-17 18:14:43 +00005356- unittest now verifies more of its assumptions. In particular,
5357 TestCase and TestSuite subclasses (not instances) are no longer
5358 accepted in TestSuite.addTest(). This should cause no
5359 incompatibility since it never made sense with ordinary subclasses
5360 -- the failure just occurred later, with a more cumbersome
5361 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00005362

5370 given a unicode argument and os.listdir() returns unicode filenames.
5371
Georg Brandl3ee81df2008-05-17 18:14:43 +00005372- Patch #1673619: setup.py identifies extension modules it doesn't

5374 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005750 time so that opening a database previously created with the DB_DUP
5751 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5752 opens. Specifically: dictionary assignment to a DB object will
5753 replace all values for a given key when the database allows
5754 duplicate values. DB users should use DB.put(k, v) when they want
5755 to store duplicates; not DB[k] = v.

5762 characters with ASCII value less than 32. Also, it correctly quotes
5763 dots only if they occur on a single line, as opposed to the previous
5764 behavior of quoting dots if they are the second character of any
5765 line.
