Ezio Melottiab2eb0e2010-06-05 19:21:32 +000069- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
70 start byte and the continuation byte(s) are now considered invalid, instead
71 of the number of bytes specified by the start byte.
72 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
73 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
74 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
75 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +000077- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +000078 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
79 arises from the "Overriding __eq__ blocks inheritance ..." warning
80 when turned into an exception: in this case the exception simply
81 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +000083- Issue #8748: Fix two issues with comparisons between complex and integer
84 objects. (1) The comparison could incorrectly return True in some cases
85 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
86 (2) The comparison raised an OverflowError for large integers, leading
87 to unpredictable exceptions when combining integers and complex objects
88 in sets or dicts.
89
Mark Dickinson81336372010-05-30 12:12:25 +000090- Issue #5211: Implicit coercion for the complex type is now completely
91 removed. (Coercion for arithmetic operations was already removed in 2.7
92 alpha 4, but coercion for rich comparisons was accidentally left in.)
93
Victor Stinnerc49dfcc2010-05-25 22:30:32 +000094- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
95 and error handler, instead of writing to the C stderr file in utf-8
96
Georg Brandlfee0f442010-05-22 21:26:21 +000097- Issue #7902: When using explicit relative import syntax, don't try implicit

282 operation raises multiple signals and more than one of those signals is
283 trapped, the specification determines the order in which the signals should be
284 handled. In many cases this order wasn't being followed, leading to the wrong
285 Python exception being raised.

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

527 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
528 signaling NaNs remain unhashable.

532 returned an arbitrary result based on the relative ordering of id(float) and
533 id(Decimal).

537 read on demand and the named file is compiled immediately. (Original patch by

549 makes Fraction <=> complex comparisons consistent with int <=> complex, float
550 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +0000958 file position when calling `truncate()`. It would previously change the file
959 position to the given argument, which goes against the tradition of

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

Georg Brandlba83f822010-03-14 09:50:54 +00001059- The ``__complex__()`` method is now looked up on the class of instances to
1060 make it consistent with other special methods.

1064
Mark Dickinson1b34d252010-01-01 17:27:30 +00001065- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001066 DeprecationWarning when passed a float argument where an integer was expected.
1067 These functions and methods now raise TypeError instead. The majority of the
1068 effects of this change are in the extension modules, but some core functions
1069 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1070 and many unicode/str methods.

1085 least on IEEE 754 platforms), and in particular does not depend on the
1086 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001253- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1254 decimal string that's guaranteed to round back to x under correct rounding
1255 (with round-half-to-even rounding mode). Previously it gave a string based on
1256 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1257 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1258 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001260- Issue #7117: On almost all platforms: float-to-string and string-to-float
1261 conversions within Python are now correctly rounded. Places these conversions
1262 occur include: str for floats and complex numbers; the float and complex
1263 constructors; old-style and new-style numeric formatting; serialization and
1264 deserialization of floats and complex numbers using marshal, pickle and json;
1265 parsing of float and imaginary literals in Python code; Decimal-to-float
1266 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001267
Georg Brandlba83f822010-03-14 09:50:54 +00001268 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1269 providing correctly-rounded strtod and dtoa C functions. This code is
1270 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1271 the C compiler. There may be a small number of platforms on which correct
1272 operation of this code cannot be guaranteed, so the code is not used: notably,
1273 this applies to platforms where the C double format is not IEEE 754 binary64,
1274 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1275 and Python's configure script is unable to determine how to change the FPU
1276 precision. On these platforms conversions use the platform strtod and dtoa,
1277 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001279- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1280 uses the correctly-rounded string <-> float conversions described above (when
1281 available), and so produces correctly rounded results that will display nicely
1282 under the float repr. There are two related small changes: (1) round now
1283 accepts any class with an ``__index__()`` method for its second argument (but
1284 no longer accepts floats for the second argument), and (2) an excessively
1285 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1286 raises an exception.

3071 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

3170 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3171 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003238What's New in Python 2.6 beta 3?
3239================================
3240
Barry Warsaw07a4a382008-08-21 01:15:08 +00003241*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003242
3243Core and Builtins
3244-----------------
3245
Guido van Rossumf8402962008-08-20 15:01:50 +00003246- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3247 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3248 extensions do not automatically benefit from the class attribute
3249 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3250 to their tp_flags field if they care. This is a backwards
3251 compatibility feature; in 3.0, all types will use the cache by
3252 default.
3253
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003254- Keyword arguments can now follow starred arguments. (``f(a, *args,
3255 keyword=23)`` is now valid syntax.)
3256
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003257- ctypes function pointers that are COM methods have a boolean True
3258 value again.
3259
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003260- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3261 by denying s# to parse objects that have a releasebuffer procedure,
3262 and introducing s*.
3263
Georg Brandl1e13ea92008-08-11 09:07:59 +00003264- Issue #3537: Fix an assertion failure when an empty but presized dict
3265 object was stored in the freelist.
3266
Mark Dickinsonb6467572008-08-04 21:30:09 +00003267- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3268 ValueError consistently across platforms.
3269
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003270- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3271 (64bit Unix, for example), unichr() would truncate its argument and return
3272 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3273
Neal Norwitze7d8be82008-07-31 17:17:14 +00003274- Apply security patches from Apple.
3275
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003276- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3277 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3278
Antoine Pitrou92f82162008-07-25 22:22:08 +00003279- Issue #1819: function calls with several named parameters are now on
3280 average 35% faster (as measured by pybench).
3281
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003282- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3283 the python debugger steps into a class statement: the free variables (local
3284 variables defined in an outer scope) would be deleted from the outer scope.
3285
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003286- Issue #2620: Overflow checking when allocating or reallocating memory
3287 was not always being done properly in some python types and extension
3288 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3289 all been updated to perform better checks and places in the code that
3290 would previously leak memory on the error path when such an allocation
3291 failed have been fixed.

3295
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003296- Issue #3612: Added some missing basic types in ctypes.wintypes.
3297
Benjamin Petersone977ad42008-08-20 01:42:01 +00003298- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3299 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3300
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003301- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3302 version reported by these tools does not necessarily follow the python
3303 version numbering scheme, so the module is less strict when parsing it.
3304
Nick Coghlanf70385a2008-08-18 12:42:46 +00003305- Issue #2235: Added Py3k warnings for types which will become unhashable
3306 under the stricter __hash__ inheritance rules in 3.0. Several types
3307 which did not meet the rules for hash invariants and were already
3308 unhashable in 3.0 have now been explicitly flagged as unhashable in
3309 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3310 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3311
Brett Cannon88f801d2008-08-18 00:46:22 +00003312- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3313 imported into the module but exposed as part of the module's API.
3314
Brett Cannon7b96f072008-08-18 00:41:11 +00003315- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3316
Brett Cannon46225e72008-08-18 00:36:52 +00003317- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003319- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3320
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003321- Issue #3575: Incremental decoder's decode function now takes bytearray
3322 by using 's*' instead of 't#'.
3323
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003324- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003325 fails unicode conversion on 2nd parameter. (windows only)
3326
Facundo Batista94f243a2008-08-17 03:38:39 +00003327- Issue 2464. urllib2 now supports a malformation in the URL received
3328 in a redirect.
3329
Brett Cannonabe423e2008-08-16 21:47:07 +00003330- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003331 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003332
Facundo Batistaeb90b782008-08-16 14:44:07 +00003333- Issue #2776: fixed small issue when handling an URL with double slash
3334 after a 302 response in the case of not going through a proxy.
3335
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003336- Issue #2676: in the email package, content-type parsing was hanging on
3337 pathological input because of quadratic or exponential behaviour of a
3338 regular expression.
3339
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003340- Issue #3476: binary buffered reading through the new "io" library is now
3341 thread-safe.
3342
Brett Cannonbf3157b2008-08-14 05:00:03 +00003343- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3344 since mimetools itself is deprecated. Because modules are cached, all
3345 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3346
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003347- Issue #3134: shutil referenced undefined WindowsError symbol.
3348
Robert Schuppenies14646332008-08-10 11:01:53 +00003349- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3350 menu entries were not deleted.
3351
Brett Cannon83e81842008-08-09 23:30:55 +00003352- Copied the implementation of reduce() to _functools.reduce() to have a
3353 version that did not raise a DeprecationWarning under -3.
3354
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003355- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3356 a MemoryError rather than silently stop the iteration.
3357
Guido van Rossum59ce9012008-08-09 14:55:34 +00003358- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3359 to _sre.compile() will now be rejected. This should not affect anybody
3360 since the re.compile() function never generates invalid re-bytecode.
3361
Skip Montanaroa032bf42008-08-08 22:52:51 +00003362- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3363 upon first access it can be automatically initialized from the csv file if
3364 it wasn't initialized during instantiation.
3365
Brett Cannon3aa2a492008-08-06 22:28:09 +00003366- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3367 the reload() built-in has been removed.
3368
Brett Cannon7e30b672008-08-04 21:52:25 +00003369- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003370 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003381 asking for a specific length. This problem only affected files opened
3382 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003383

3425
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003426- Issue #643841: The language reference now provides more detailed

3433================================
3434
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003435*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003437Core and Builtins
3438-----------------
3439
Georg Brandl3e483f62008-07-16 22:57:41 +00003440- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3441 its methods now allow for items objects that can be converted to
3442 an integer using operator.index().
3443
Mark Dickinson64b7e502008-07-16 09:40:03 +00003444- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3445 produced a ValueError instead of giving the correct float.
3446
Eric Smitha5fa5a22008-07-16 00:11:49 +00003447- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3448 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3449
Mark Dickinson7103aa42008-07-15 19:08:33 +00003450- Issue #3008: the float type has a new instance method 'float.hex'
3451 and a new class method 'float.fromhex' to convert floating-point
3452 numbers to and from hexadecimal strings, respectively.
3453
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003454- Issue #2235: __hash__ is once again inherited by default. To allow
3455 collections.Hashable to remain meaningful in the presence of the
3456 default hash implementation (object.__hash__), it is now possible
3457 to explicit block inheritance of hash by setting __hash__=None at
3458 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3459 level.
3460
Nick Coghlanb028f502008-07-13 14:52:36 +00003461- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3462 the parent module cannot be found while performing an absolute import.
3463 This means that an incorrectly defined __package__ attribute will
3464 now only prevent relative imports in that module rather than causing
3465 all imports from that module to fail.
3466
Nick Coghlan14ff9942008-07-08 14:21:42 +00003467- Issue #2517: Allow unicode messages in Exceptions again by correctly
3468 bypassing the instance dictionary when looking up __unicode__ on
3469 new-style classes.

3472 set to a custom object whose write() method happens to install
3473 another file in sys.stdout.
3474
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003475- Issue #3088: Corrected a race condition in classes derived from
3476 threading.local: the first member set by a thread could be saved in
3477 another thread's dictionary.
3478
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003479- Issue #3004: Minor change to slice.indices(): the start and stop
3480 arguments are now treated identically, making the behaviour easier
3481 to describe and understand. For example, slice(None, -10,
3482 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3483 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3484 10, -1).
3485
Georg Brandl278fc502008-07-19 12:46:12 +00003486- Issue #3219: Calling a function with repeated keyword arguments,
3487 f(a=2, a=23), would not cause a syntax error. This was a regression
3488 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003489
Georg Brandl278fc502008-07-19 12:46:12 +00003490- Issue #2862: Make int and float freelist management consistent with
3491 other freelists. Changes their CompactFreeList apis into
3492 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003497- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3498 api functions without holding the GIL, which could lead to a fatal
3499 error when they failed.
3500
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003501- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003526- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3527 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003528 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003529 content-length. The problem had been corrected in the 2.4 branch, but never
3530 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003545- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3546 handling is now the same as that of other special attributes like __name__).
3547
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003548- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00004000- Issue #1631171: Re-implement the 'warnings' module in C (the
4001 original Python code has been kept as backup). This will allow for
4002 using the 'warning's machinery in such places as the parser where
4003 use of pure Python code is not possible. Both the ``showarning()``
4004 and ``formatwarning()`` gain an optional 'line' argument which is
4005 not called by default for backwards-compatibility reasons. Setting
4006 ``warnings.showwarning()`` to an implementation that lacks support
4007 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004070- Issue #2550: The approach used by client/server code for obtaining
4071 ports to listen on in network-oriented tests has been refined in an
4072 effort to facilitate running multiple instances of the entire
4073 regression test suite in parallel without issue.
4074 test_support.bind_port() has been fixed such that it will always
4075 return a unique port -- which wasn't always the case with the
4076 previous implementation, especially if socket options had been set
4077 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4078 new implementation of bind_port() will actually raise an exception
4079 if it is passed an AF_INET/SOCK_STREAM socket with either the
4080 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4081 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4082 the socket it's been passed. This currently only applies to
4083 Windows. This option prevents any other sockets from binding to the
4084 host/port we've bound to, thus removing the possibility of the
4085 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4086 when a second SOCK_STREAM socket binds and accepts to a host/port
4087 that's already been bound by another socket. The optional preferred
4088 port parameter to bind_port() has been removed. Under no
4089 circumstances should tests be hard coding ports!
4090
4091 test_support.find_unused_port() has also been introduced, which will
4092 pass a temporary socket object to bind_port() in order to obtain an
4093 unused port. The temporary socket object is then closed and
4094 deleted, and the port is returned. This method should only be used
4095 for obtaining an unused port in order to pass to an external program
4096 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4097 a parameter to a server-oriented class that doesn't give you direct
4098 access to the underlying socket used.
4099
4100 Finally, test_support.HOST has been introduced, which should be used
4101 for the host argument of any relevant socket calls (i.e. bind and
4102 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004103
4104 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004105 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004106 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4107 test_asynchat and test_socket_ssl.
4108
Georg Brandl3ee81df2008-05-17 18:14:43 +00004109 It is now possible for multiple instances of the regression test
4110 suite to run in parallel without issue.

4377-----------------
4378
Fred Drakea8ee94b2008-03-01 02:45:07 +00004379- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004380 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00004385
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004386- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004387 issue 215555 for a discussion.
4388
Eric Smitha73fbe72008-02-23 03:09:44 +00004389- Added the future_builtins module, which contains hex() and oct().
4390 These are the PEP 3127 version of these functions, designed to be
4391 compatible with the hex() and oct() builtins from Python 3.0. They
4392 differ slightly in their output formats from the existing, unchanged
4393 Python 2.6 builtins. The expected usage of the future_builtins
4394 module is:
4395 from future_builtins import hex, oct
4396
Eric Smith7ef40bf2008-02-20 23:34:22 +00004397- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4398 exponents for exponents with absolute value < 100. Follows C99
4399 standard. This is a change on Windows, which would use 3 digits.
4400 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4401 so that any alterations it does to the resulting string will be
4402 available in stringlib/formatter.h (for float.__format__).
4403
Eric Smith5a3c1352008-02-19 13:21:56 +00004404- Implemented PEP 3101, Advanced String Formatting. This adds a new
4405 builtin format(); a format() method for str and unicode; a
4406 __format__() method to object, str, unicode, int, long, float, and
4407 datetime; the class string.Formatter; and the C API
4408 PyObject_Format().
4409
Georg Brandl3ee81df2008-05-17 18:14:43 +00004410- Fixed several potential crashes, all caused by specially crafted
4411 __del__ methods exploiting objects in temporarily inconsistent
4412 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004413
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004414- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004415 prevent a possible crash: an Abstract Base Class would try to access
4416 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004421- Clear all free lists during a gc.collect() of the highest generation
4422 in order to allow pymalloc to free more arenas. Python may give back
4423 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004424
Georg Brandl3ee81df2008-05-17 18:14:43 +00004425- Issue #2045: Fix an infinite recursion triggered when printing a
4426 subclass of collections.defaultdict, if its default_factory is set
4427 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004428
Christian Heimesf75dbef2008-02-08 00:11:31 +00004429- Fixed a minor memory leak in dictobject.c. The content of the free
4430 list was not freed on interpreter shutdown.
4431
Georg Brandl21e99f42010-03-07 15:23:59 +00004432- Limit free list of method and built-in function objects to 256

4436 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004437 to compact the internal free lists of pre-allocted ints and floats.
4438
Georg Brandl3ee81df2008-05-17 18:14:43 +00004439- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4440 calls. Python expected the return type int but the fork familie
4441 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004455- Patch #1473257: generator objects gain a gi_code attribute. This is
4456 the same object as the func_code attribute of the function that
4457 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004458
Georg Brandl3ee81df2008-05-17 18:14:43 +00004459- Issue #1920: "while 0" statements were completely removed by the
4460 compiler, even in the presence of an "else" clause, which is
4461 supposed to be run when the condition is false. Now the compiler
4462 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004463

4471
Georg Brandl3ee81df2008-05-17 18:14:43 +00004472- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004473 several extension methods and modules do not work without unicode
4474 support.

Georg Brandl6caad7d2008-01-26 14:19:22 +00004481- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004482 added.
4483
Christian Heimesc94e2b52008-01-14 04:13:37 +00004484- sys.float_info / PyFloat_GetInfo: The floating point information
4485 object was converted from a dict to a specialized structseq object.
4486
Georg Brandl3ee81df2008-05-17 18:14:43 +00004487- Patch #1816: Added sys.flags structseq. It exposes the status of
4488 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004489
Georg Brandl3ee81df2008-05-17 18:14:43 +00004490- Objects/structseq.c: Implemented new structseq representation. The
4491 patch makes structseqs (e.g. the return value of os.stat) more
4492 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004493
Georg Brandl3ee81df2008-05-17 18:14:43 +00004494- Patch #1700288: added a type attribute cache that caches method
4495 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004496
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004497- Bug #1776: __import__() no longer accepts filenames on any platform.
4498 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004499
Georg Brandlaed6c662008-01-07 17:25:53 +00004500- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4501
Georg Brandl3ee81df2008-05-17 18:14:43 +00004502- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4503 envvar and sys.dont_write_bytecode attribute. All these can be set
4504 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004505
Georg Brandl3ee81df2008-05-17 18:14:43 +00004506- Improve some exception messages when Windows fails to load an
4507 extension module. Now we get for example '%1 is not a valid Win32
4508 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004509

Georg Brandl3ee81df2008-05-17 18:14:43 +00004512- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4513 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004514
Christian Heimes0a8143f2007-12-18 23:22:54 +00004515- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004516 and INF. float("nan"), float("inf") and float("-inf") now work on
4517 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004518
Georg Brandl3ee81df2008-05-17 18:14:43 +00004519- Compiler now generates simpler and faster code for dictionary
4520 literals. The oparg for BUILD_MAP now indicates an estimated
4521 dictionary size. There is a new opcode, STORE_MAP, for adding
4522 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004551- Patch #1739468: Directories and zipfiles containing a __main__.py
4552 file can now be directly executed by passing their name to the
4553 interpreter. The directory/zipfile is automatically inserted as the
4554 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004555
Georg Brandl3ee81df2008-05-17 18:14:43 +00004556- Issue #1265: Fix a problem with sys.settrace, if the tracing
4557 function uses a generator expression when at the same time the
4558 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004559
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004560- sets and frozensets now have an isdisjoint() method.
4561

4563
Neal Norwitz44f326e2007-10-05 05:29:17 +00004564- Fix warnings found by the new version of the Coverity checker.
4565
Georg Brandl21e99f42010-03-07 15:23:59 +00004566- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004567 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4568 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004569
Georg Brandl3ee81df2008-05-17 18:14:43 +00004570- Issue #1686386: Tuple's tp_repr did not take into account the
4571 possibility of having a self-referential tuple, which is possible
4572 from C code. Nor did object's tp_str consider that a type's tp_str
4573 could do something that could lead to an inifinite recursion.
4574 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4575 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004576
Georg Brandl3ee81df2008-05-17 18:14:43 +00004577- Issue #1164: It was possible to trigger deadlock when using the
4578 'print' statement to write to a file since the GIL was not released
4579 as needed. Now PyObject_Print() does the right thing along with
4580 various tp_print implementations of the built-in types and those in
4581 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004582
Georg Brandl3ee81df2008-05-17 18:14:43 +00004583- Issue #1147: Exceptions were directly allowing string exceptions in
4584 their throw() method even though string exceptions no longer
4585 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004586
Georg Brandl3ee81df2008-05-17 18:14:43 +00004587- Issue #1096: Prevent a segfault from getting the repr of a very
4588 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004589
Brett Cannon1e534b52007-09-07 04:18:30 +00004590- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004591 PyObject_Call() never calling back out to Python code to trigger
4592 recursion depth updates/checks. Required the creation of a static
4593 RuntimeError instance in case normalizing an exception put the
4594 recursion check value past its limit. Fixes crashers
4595 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004596

Neal Norwitz0ac60192007-05-27 04:08:54 +00004610- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004611 __*__ attributes. (Some already existed, e.g., __doc__ and
4612 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004613
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004614- Add -3 option to the interpreter to warn about features that are
4615 deprecated and will be changed/removed in Python 3.0.
4616
Georg Brandl2134e752007-05-21 20:34:16 +00004617- Patch #1686487: you can now pass any mapping after '**' in function
4618 calls.
4619
Collin Winter62903052007-05-18 23:11:24 +00004620- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004621 "except E as target:". This is to provide forwards compatibility
4622 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004623
Brett Cannon229cee22007-05-05 01:34:02 +00004624- Deprecate BaseException.message as per PEP 352.
4625
Georg Brandl3ee81df2008-05-17 18:14:43 +00004626- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004627 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004628
Vinay Sajip8549ce32007-05-06 17:53:37 +00004629- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004630 setting a plain string, ie don't expand to single letter identifiers.
4631
Raymond Hettinger13936692007-04-11 18:40:58 +00004632- Request #1191699: Slices can now be pickled.
4633
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004634- Request #1193128: str.translate() now allows a None argument for
4635 translations that only remove characters without re-mapping the
4636 remaining characters.
4637
Georg Brandl5cb76c12007-03-21 09:00:39 +00004638- Patch #1682205: a TypeError while unpacking an iterable is no longer
4639 masked by a generic one with the message "unpack non-sequence".
4640
Neal Norwitzaa754b72007-03-21 06:39:48 +00004641- Remove unused file Python/fmod.c.
4642
Guido van Rossum143b5642007-03-23 04:58:42 +00004643- Bug #1683368: The object.__init__() and object.__new__() methods are
4644 now stricter in rejecting excess arguments. The only time when
4645 either allows excess arguments is when it is not overridden and the
4646 other one is. For backwards compatibility, when both are
4647 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004648 warning later). Also, type.__init__() insists on the same signature
4649 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004650
Georg Brandl3ee81df2008-05-17 18:14:43 +00004651- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4652 object to complex using its __complex__() method before falling back
4653 to the __float__() method. Therefore, the functions in the cmath
4654 module now can operate on objects that define a __complex__()
4655 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004656
Georg Brandl3ee81df2008-05-17 18:14:43 +00004657- Patch #1623563: allow __class__ assignment for classes with
4658 __slots__. The old and the new class are still required to have the
4659 same slot names.

4665 ``object.__reduce_ex__()`` is called with an object that is faking
4666 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004667
Georg Brandl3ee81df2008-05-17 18:14:43 +00004668- Patch #1680015: Don't modify __slots__ tuple if it contains an

4672
Georg Brandl7b9c5552007-03-12 14:30:05 +00004673- Bug #1678647: write a newline after printing an exception in any
4674 case, even when converting the value to a string failed.
4675
Georg Brandl871f1bc2007-03-12 13:17:36 +00004676- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004677 its argument, if it exists. If not, it will work like before. This
4678 allows customizing the output of dir() in the presence of a
4679 __getattr__().

4683
Georg Brandl3ee81df2008-05-17 18:14:43 +00004684- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004687- Patch #1491866: change the complex() constructor to allow
4688 parthensized forms. This means complex(repr(x)) now works instead of
4689 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004690
Georg Brandlaa2321b2007-03-07 00:40:28 +00004691- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004692 makes the filenames the warning module prints much more sensible
4693 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004694
Georg Brandl49aafc92007-03-07 00:34:46 +00004695- Variant of patch #697613: don't exit the interpreter on a SystemExit
4696 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004697 variable is given, but break into the interactive interpreter just
4698 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004706- Patch #1674228: when assigning a slice (old-style), check for the
4707 sq_ass_slice instead of the sq_slice slot.
4708
Georg Brandl3ee81df2008-05-17 18:14:43 +00004709- When printing an unraisable error, don't print exceptions. before
4710 the name. This duplicates the behavior whening normally printing
4711 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005213- Added a timeout parameter to the constructor of other protocols
5214 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5215 work started with create_connection() and timeout in httplib, and
5216 closes patch #723312.
5217
Vinay Sajip8549ce32007-05-06 17:53:37 +00005218- Patch #1676823: Added create_connection() to socket.py, which may be

5242
Georg Brandlf66b6032007-03-14 08:27:52 +00005243- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005244 AttributeError instead of an IOError when the server's response
5245 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005246
Georg Brandl3ee81df2008-05-17 18:14:43 +00005247- Patch #957650: "%var%" environment variable references are now

Georg Brandl3ee81df2008-05-17 18:14:43 +00005251- Patch #1429539: pdb now correctly initializes the __main__ module
5252 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005253 correctly now.
5254

5261
Georg Brandl3ee81df2008-05-17 18:14:43 +00005262- Patch #1530482: add pydoc.render_doc() which returns the

5273 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00005275- Patch #1581073: add a flag to textwrap that prevents the dropping of
5276 whitespace while wrapping.
5277
Georg Brandl92a6bae2007-03-13 17:43:32 +00005278- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005279 are set for invalid interpolation sequences that would lead to
5280 errors on reading back those values.

5323 returned string up to the first NUL character.

5334
Georg Brandl3ee81df2008-05-17 18:14:43 +00005335- unittest now verifies more of its assumptions. In particular,
5336 TestCase and TestSuite subclasses (not instances) are no longer
5337 accepted in TestSuite.addTest(). This should cause no
5338 incompatibility since it never made sense with ordinary subclasses
5339 -- the failure just occurred later, with a more cumbersome
5340 exception.

5350
Georg Brandl3ee81df2008-05-17 18:14:43 +00005351- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00005729 time so that opening a database previously created with the DB_DUP
5730 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5731 opens. Specifically: dictionary assignment to a DB object will
5732 replace all values for a given key when the database allows
5733 duplicate values. DB users should use DB.put(k, v) when they want
5734 to store duplicates; not DB[k] = v.

5741 characters with ASCII value less than 32. Also, it correctly quotes
5742 dots only if they occur on a single line, as opposed to the previous
5743 behavior of quoting dots if they are the second character of any
5744 line.
