Ezio Melottiab2eb0e2010-06-05 19:21:32 +000089- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
90 start byte and the continuation byte(s) are now considered invalid, instead
91 of the number of bytes specified by the start byte.
92 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
93 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
94 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
95 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +000097- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +000098 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
99 arises from the "Overriding __eq__ blocks inheritance ..." warning
100 when turned into an exception: in this case the exception simply
101 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000103- Issue #8748: Fix two issues with comparisons between complex and integer
104 objects. (1) The comparison could incorrectly return True in some cases
105 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
106 (2) The comparison raised an OverflowError for large integers, leading
107 to unpredictable exceptions when combining integers and complex objects
108 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +0000110- Issue #5211: Implicit coercion for the complex type is now completely
111 removed. (Coercion for arithmetic operations was already removed in 2.7
112 alpha 4, but coercion for rich comparisons was accidentally left in.)
113
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000114- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

116
Georg Brandlfee0f442010-05-22 21:26:21 +0000117- Issue #7902: When using explicit relative import syntax, don't try implicit

Georg Brandlfee0f442010-05-22 21:26:21 +0000301- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
302 operation raises multiple signals and more than one of those signals is

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

Georg Brandlfee0f442010-05-22 21:26:21 +0000545- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
546 InvalidOperation instead of returning False. (Comparisons involving a quiet
547 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
548 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +0000550- Issue #2531: Comparison operations between floats and Decimal instances now
551 return a result based on the numeric values of the operands; previously they
552 returned an arbitrary result based on the relative ordering of id(float) and
553 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000554
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000555- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000556 argument `-` which tells it to read files to compile from stdin. Each line is
557 read on demand and the named file is compiled immediately. (Original patch by
558 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000567- Comparisons using one of <, <=, >, >= between a complex instance and a
568 Fractions instance now raise TypeError instead of returning True/False. This
569 makes Fraction <=> complex comparisons consistent with int <=> complex, float
570 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +0000674- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
675 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +0000677 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
678 inconsistent: __int__ was used for some integer codes but not for others, and
679 the set of integer codes for which it was used differed between native packing
680 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000978 file position when calling `truncate()`. It would previously change the file
979 position to the given argument, which goes against the tradition of

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

Georg Brandlba83f822010-03-14 09:50:54 +00001077- The ``__complex__()`` method is now looked up on the class of instances to
1078 make it consistent with other special methods.

1082
Mark Dickinson1b34d252010-01-01 17:27:30 +00001083- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001084 DeprecationWarning when passed a float argument where an integer was expected.
1085 These functions and methods now raise TypeError instead. The majority of the
1086 effects of this change are in the extension modules, but some core functions
1087 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1088 and many unicode/str methods.

1103 least on IEEE 754 platforms), and in particular does not depend on the
1104 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001271- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1272 decimal string that's guaranteed to round back to x under correct rounding
1273 (with round-half-to-even rounding mode). Previously it gave a string based on
1274 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1275 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1276 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001278- Issue #7117: On almost all platforms: float-to-string and string-to-float
1279 conversions within Python are now correctly rounded. Places these conversions
1280 occur include: str for floats and complex numbers; the float and complex
1281 constructors; old-style and new-style numeric formatting; serialization and
1282 deserialization of floats and complex numbers using marshal, pickle and json;
1283 parsing of float and imaginary literals in Python code; Decimal-to-float
1284 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001285
Georg Brandlba83f822010-03-14 09:50:54 +00001286 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1287 providing correctly-rounded strtod and dtoa C functions. This code is
1288 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1289 the C compiler. There may be a small number of platforms on which correct
1290 operation of this code cannot be guaranteed, so the code is not used: notably,
1291 this applies to platforms where the C double format is not IEEE 754 binary64,
1292 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1293 and Python's configure script is unable to determine how to change the FPU
1294 precision. On these platforms conversions use the platform strtod and dtoa,
1295 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001297- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1298 uses the correctly-rounded string <-> float conversions described above (when
1299 available), and so produces correctly rounded results that will display nicely
1300 under the float repr. There are two related small changes: (1) round now
1301 accepts any class with an ``__index__()`` method for its second argument (but
1302 no longer accepts floats for the second argument), and (2) an excessively
1303 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1304 raises an exception.

1719 gives improved memory leak detection when running under Valgrind, while taking
1720 advantage of pymalloc at other times.

2887 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2888 neither __int__ nor __long__, TypeError used to be raised (with a

3089 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3090 ``printf`` function, whereas PyString_FromFormat has an independent

3114 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3115 when given a tuple of classes as second argument, were looking up
3116 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3117 type object.
3118
Neal Norwitz18aa3882008-08-24 05:04:52 +00003119- Fix crashes on memory allocation failure found with failmalloc.

3188 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3189 for catch_warnings() also led to an improvement in the raising of a
3190 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003256What's New in Python 2.6 beta 3?
3257================================
3258
Barry Warsaw07a4a382008-08-21 01:15:08 +00003259*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003260
3261Core and Builtins
3262-----------------
3263
Guido van Rossumf8402962008-08-20 15:01:50 +00003264- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3265 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3266 extensions do not automatically benefit from the class attribute
3267 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3268 to their tp_flags field if they care. This is a backwards
3269 compatibility feature; in 3.0, all types will use the cache by
3270 default.
3271
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003272- Keyword arguments can now follow starred arguments. (``f(a, *args,
3273 keyword=23)`` is now valid syntax.)
3274
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003275- ctypes function pointers that are COM methods have a boolean True
3276 value again.
3277
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003278- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3279 by denying s# to parse objects that have a releasebuffer procedure,
3280 and introducing s*.
3281
Georg Brandl1e13ea92008-08-11 09:07:59 +00003282- Issue #3537: Fix an assertion failure when an empty but presized dict
3283 object was stored in the freelist.
3284
Mark Dickinsonb6467572008-08-04 21:30:09 +00003285- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3286 ValueError consistently across platforms.
3287
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003288- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3289 (64bit Unix, for example), unichr() would truncate its argument and return
3290 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3291
Neal Norwitze7d8be82008-07-31 17:17:14 +00003292- Apply security patches from Apple.
3293
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003294- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3295 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3296
Antoine Pitrou92f82162008-07-25 22:22:08 +00003297- Issue #1819: function calls with several named parameters are now on
3298 average 35% faster (as measured by pybench).
3299
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003300- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3301 the python debugger steps into a class statement: the free variables (local
3302 variables defined in an outer scope) would be deleted from the outer scope.
3303
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003304- Issue #2620: Overflow checking when allocating or reallocating memory
3305 was not always being done properly in some python types and extension
3306 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3307 all been updated to perform better checks and places in the code that
3308 would previously leak memory on the error path when such an allocation
3309 failed have been fixed.

3313
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003314- Issue #3612: Added some missing basic types in ctypes.wintypes.
3315
Benjamin Petersone977ad42008-08-20 01:42:01 +00003316- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3317 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3318
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003319- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3320 version reported by these tools does not necessarily follow the python
3321 version numbering scheme, so the module is less strict when parsing it.
3322
Nick Coghlanf70385a2008-08-18 12:42:46 +00003323- Issue #2235: Added Py3k warnings for types which will become unhashable
3324 under the stricter __hash__ inheritance rules in 3.0. Several types
3325 which did not meet the rules for hash invariants and were already
3326 unhashable in 3.0 have now been explicitly flagged as unhashable in
3327 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3328 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3329
Brett Cannon88f801d2008-08-18 00:46:22 +00003330- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3331 imported into the module but exposed as part of the module's API.
3332
Brett Cannon7b96f072008-08-18 00:41:11 +00003333- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3334
Brett Cannon46225e72008-08-18 00:36:52 +00003335- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003337- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3338
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003339- Issue #3575: Incremental decoder's decode function now takes bytearray
3340 by using 's*' instead of 't#'.
3341
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003342- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003343 fails unicode conversion on 2nd parameter. (windows only)
3344
Facundo Batista94f243a2008-08-17 03:38:39 +00003345- Issue 2464. urllib2 now supports a malformation in the URL received
3346 in a redirect.
3347
Brett Cannonabe423e2008-08-16 21:47:07 +00003348- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003349 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003350
Facundo Batistaeb90b782008-08-16 14:44:07 +00003351- Issue #2776: fixed small issue when handling an URL with double slash
3352 after a 302 response in the case of not going through a proxy.
3353
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003354- Issue #2676: in the email package, content-type parsing was hanging on
3355 pathological input because of quadratic or exponential behaviour of a
3356 regular expression.
3357
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003358- Issue #3476: binary buffered reading through the new "io" library is now
3359 thread-safe.
3360
Brett Cannonbf3157b2008-08-14 05:00:03 +00003361- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3362 since mimetools itself is deprecated. Because modules are cached, all
3363 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3364
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003365- Issue #3134: shutil referenced undefined WindowsError symbol.
3366
Robert Schuppenies14646332008-08-10 11:01:53 +00003367- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3368 menu entries were not deleted.
3369
Brett Cannon83e81842008-08-09 23:30:55 +00003370- Copied the implementation of reduce() to _functools.reduce() to have a
3371 version that did not raise a DeprecationWarning under -3.
3372
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003373- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3374 a MemoryError rather than silently stop the iteration.
3375
Guido van Rossum59ce9012008-08-09 14:55:34 +00003376- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3377 to _sre.compile() will now be rejected. This should not affect anybody
3378 since the re.compile() function never generates invalid re-bytecode.
3379
Skip Montanaroa032bf42008-08-08 22:52:51 +00003380- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3381 upon first access it can be automatically initialized from the csv file if
3382 it wasn't initialized during instantiation.
3383
Brett Cannon3aa2a492008-08-06 22:28:09 +00003384- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3385 the reload() built-in has been removed.
3386
Brett Cannon7e30b672008-08-04 21:52:25 +00003387- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003388 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003399 asking for a specific length. This problem only affected files opened

3456-----------------
3457
Georg Brandl3e483f62008-07-16 22:57:41 +00003458- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3459 its methods now allow for items objects that can be converted to
3460 an integer using operator.index().
3461
Mark Dickinson64b7e502008-07-16 09:40:03 +00003462- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3463 produced a ValueError instead of giving the correct float.
3464
Eric Smitha5fa5a22008-07-16 00:11:49 +00003465- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3466 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3467
Mark Dickinson7103aa42008-07-15 19:08:33 +00003468- Issue #3008: the float type has a new instance method 'float.hex'
3469 and a new class method 'float.fromhex' to convert floating-point
3470 numbers to and from hexadecimal strings, respectively.
3471
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003472- Issue #2235: __hash__ is once again inherited by default. To allow
3473 collections.Hashable to remain meaningful in the presence of the
3474 default hash implementation (object.__hash__), it is now possible
3475 to explicit block inheritance of hash by setting __hash__=None at
3476 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3477 level.
3478
Nick Coghlanb028f502008-07-13 14:52:36 +00003479- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3480 the parent module cannot be found while performing an absolute import.
3481 This means that an incorrectly defined __package__ attribute will
3482 now only prevent relative imports in that module rather than causing
3483 all imports from that module to fail.
3484
Nick Coghlan14ff9942008-07-08 14:21:42 +00003485- Issue #2517: Allow unicode messages in Exceptions again by correctly

3494 threading.local: the first member set by a thread could be saved in
3495 another thread's dictionary.
3496
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003497- Issue #3004: Minor change to slice.indices(): the start and stop
3498 arguments are now treated identically, making the behaviour easier
3499 to describe and understand. For example, slice(None, -10,
3500 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3501 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3502 10, -1).
3503
Georg Brandl278fc502008-07-19 12:46:12 +00003504- Issue #3219: Calling a function with repeated keyword arguments,
3505 f(a=2, a=23), would not cause a syntax error. This was a regression
3506 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003507
Georg Brandl278fc502008-07-19 12:46:12 +00003508- Issue #2862: Make int and float freelist management consistent with
3509 other freelists. Changes their CompactFreeList apis into
3510 ClearFreeList apis and calls them via gc.collect().

3516 api functions without holding the GIL, which could lead to a fatal
3517 error when they failed.
3518
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003519- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003544- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3545 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003546 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003547 content-length. The problem had been corrected in the 2.4 branch, but never
3548 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003563- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3564 handling is now the same as that of other special attributes like __name__).
3565
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003566- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Christian Heimes7a990612008-05-26 13:15:11 +00003977
3978- The PyString functions have been renamed to PyBytes. A batch of
3979 defines were added so that the linker still sees the original
3980 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004018- Issue #1631171: Re-implement the 'warnings' module in C (the
4019 original Python code has been kept as backup). This will allow for
4020 using the 'warning's machinery in such places as the parser where
4021 use of pure Python code is not possible. Both the ``showarning()``
4022 and ``formatwarning()`` gain an optional 'line' argument which is
4023 not called by default for backwards-compatibility reasons. Setting
4024 ``warnings.showwarning()`` to an implementation that lacks support
4025 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004067- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004068 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004088- Issue #2550: The approach used by client/server code for obtaining
4089 ports to listen on in network-oriented tests has been refined in an
4090 effort to facilitate running multiple instances of the entire
4091 regression test suite in parallel without issue.
4092 test_support.bind_port() has been fixed such that it will always
4093 return a unique port -- which wasn't always the case with the
4094 previous implementation, especially if socket options had been set
4095 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4096 new implementation of bind_port() will actually raise an exception
4097 if it is passed an AF_INET/SOCK_STREAM socket with either the
4098 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4099 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4100 the socket it's been passed. This currently only applies to
4101 Windows. This option prevents any other sockets from binding to the
4102 host/port we've bound to, thus removing the possibility of the
4103 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4104 when a second SOCK_STREAM socket binds and accepts to a host/port
4105 that's already been bound by another socket. The optional preferred
4106 port parameter to bind_port() has been removed. Under no
4107 circumstances should tests be hard coding ports!
4108
4109 test_support.find_unused_port() has also been introduced, which will
4110 pass a temporary socket object to bind_port() in order to obtain an
4111 unused port. The temporary socket object is then closed and
4112 deleted, and the port is returned. This method should only be used
4113 for obtaining an unused port in order to pass to an external program
4114 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4115 a parameter to a server-oriented class that doesn't give you direct
4116 access to the underlying socket used.
4117
4118 Finally, test_support.HOST has been introduced, which should be used
4119 for the host argument of any relevant socket calls (i.e. bind and
4120 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004121
4122 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004124 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4125 test_asynchat and test_socket_ssl.
4126
Georg Brandl3ee81df2008-05-17 18:14:43 +00004127 It is now possible for multiple instances of the regression test
4128 suite to run in parallel without issue.

4395-----------------
4396
Fred Drakea8ee94b2008-03-01 02:45:07 +00004397- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004398 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004400- Issue #2067: file.__exit__() now calls subclasses' close() method.
4401
4402- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004403
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004404- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004405 issue 215555 for a discussion.
4406
Eric Smitha73fbe72008-02-23 03:09:44 +00004407- Added the future_builtins module, which contains hex() and oct().
4408 These are the PEP 3127 version of these functions, designed to be
4409 compatible with the hex() and oct() builtins from Python 3.0. They
4410 differ slightly in their output formats from the existing, unchanged
4411 Python 2.6 builtins. The expected usage of the future_builtins
4412 module is:
4413 from future_builtins import hex, oct
4414
Eric Smith7ef40bf2008-02-20 23:34:22 +00004415- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4416 exponents for exponents with absolute value < 100. Follows C99
4417 standard. This is a change on Windows, which would use 3 digits.
4418 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4419 so that any alterations it does to the resulting string will be
4420 available in stringlib/formatter.h (for float.__format__).
4421
Eric Smith5a3c1352008-02-19 13:21:56 +00004422- Implemented PEP 3101, Advanced String Formatting. This adds a new
4423 builtin format(); a format() method for str and unicode; a
4424 __format__() method to object, str, unicode, int, long, float, and
4425 datetime; the class string.Formatter; and the C API
4426 PyObject_Format().
4427
Georg Brandl3ee81df2008-05-17 18:14:43 +00004428- Fixed several potential crashes, all caused by specially crafted
4429 __del__ methods exploiting objects in temporarily inconsistent
4430 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004431
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004432- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004433 prevent a possible crash: an Abstract Base Class would try to access
4434 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004435

Georg Brandl3ee81df2008-05-17 18:14:43 +00004439- Clear all free lists during a gc.collect() of the highest generation
4440 in order to allow pymalloc to free more arenas. Python may give back
4441 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004442
Georg Brandl3ee81df2008-05-17 18:14:43 +00004443- Issue #2045: Fix an infinite recursion triggered when printing a
4444 subclass of collections.defaultdict, if its default_factory is set
4445 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004446
Christian Heimesf75dbef2008-02-08 00:11:31 +00004447- Fixed a minor memory leak in dictobject.c. The content of the free
4448 list was not freed on interpreter shutdown.
4449
Georg Brandl21e99f42010-03-07 15:23:59 +00004450- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004451 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004452
Georg Brandl3ee81df2008-05-17 18:14:43 +00004453- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4454 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004455 to compact the internal free lists of pre-allocted ints and floats.
4456
Georg Brandl3ee81df2008-05-17 18:14:43 +00004457- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4458 calls. Python expected the return type int but the fork familie
4459 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004460

4471 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004472
Georg Brandl3ee81df2008-05-17 18:14:43 +00004473- Patch #1473257: generator objects gain a gi_code attribute. This is
4474 the same object as the func_code attribute of the function that
4475 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004476
Georg Brandl3ee81df2008-05-17 18:14:43 +00004477- Issue #1920: "while 0" statements were completely removed by the
4478 compiler, even in the presence of an "else" clause, which is
4479 supposed to be run when the condition is false. Now the compiler
4480 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00004482- A few crashers fixed: weakref_in_del.py (issue #1377858);
4483 loosing_dict_ref.py (issue #1303614, test67.py);
4484 borrowed_ref_[34].py (not in tracker).
4485
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004486- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004487 suppressed while an extension is loaded by calling SetErrorMode in
4488 dynload_win.c. The error is still reported properly.
4489
Georg Brandl3ee81df2008-05-17 18:14:43 +00004490- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004491 several extension methods and modules do not work without unicode
4492 support.
4493
Georg Brandl26543b12008-01-21 18:36:51 +00004494- Issue #1882: when compiling code from a string, encoding cookies in the
4495 second line of code were not always recognized correctly.
4496
Georg Brandl14404b62008-01-19 19:27:05 +00004497- Issue #1679: "0x" was taken as a valid integer literal.
4498
Georg Brandl6caad7d2008-01-26 14:19:22 +00004499- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004500 added.
4501
Christian Heimesc94e2b52008-01-14 04:13:37 +00004502- sys.float_info / PyFloat_GetInfo: The floating point information
4503 object was converted from a dict to a specialized structseq object.
4504
Georg Brandl3ee81df2008-05-17 18:14:43 +00004505- Patch #1816: Added sys.flags structseq. It exposes the status of
4506 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004507
Georg Brandl3ee81df2008-05-17 18:14:43 +00004508- Objects/structseq.c: Implemented new structseq representation. The
4509 patch makes structseqs (e.g. the return value of os.stat) more
4510 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004511
Georg Brandl3ee81df2008-05-17 18:14:43 +00004512- Patch #1700288: added a type attribute cache that caches method
4513 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004514
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004515- Bug #1776: __import__() no longer accepts filenames on any platform.
4516 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004517
Georg Brandlaed6c662008-01-07 17:25:53 +00004518- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4519
Georg Brandl3ee81df2008-05-17 18:14:43 +00004520- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4521 envvar and sys.dont_write_bytecode attribute. All these can be set
4522 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004523
Georg Brandl3ee81df2008-05-17 18:14:43 +00004524- Improve some exception messages when Windows fails to load an
4525 extension module. Now we get for example '%1 is not a valid Win32
4526 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004527
Georg Brandl3ee81df2008-05-17 18:14:43 +00004528- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004530- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4531 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004532
Christian Heimes0a8143f2007-12-18 23:22:54 +00004533- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004534 and INF. float("nan"), float("inf") and float("-inf") now work on
4535 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004536
Georg Brandl3ee81df2008-05-17 18:14:43 +00004537- Compiler now generates simpler and faster code for dictionary
4538 literals. The oparg for BUILD_MAP now indicates an estimated
4539 dictionary size. There is a new opcode, STORE_MAP, for adding
4540 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004541
Georg Brandl3ee81df2008-05-17 18:14:43 +00004542- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00004543
Georg Brandl3ee81df2008-05-17 18:14:43 +00004544- Issue #1620: New property decorator syntax was modifying the
4545 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004546
Georg Brandl3ee81df2008-05-17 18:14:43 +00004547- Issue #1538: Avoid copying string in split/rsplit if the split char
4548 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004549
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004550- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004551 SystemError.
4552
Nick Coghlanef01d822007-12-03 12:55:17 +00004553- PEP 366: Allow explicit relative imports when executing modules
4554 inside packages with the -m switch via a new module level
4555 __package__ attribute.
4556
Georg Brandl3ee81df2008-05-17 18:14:43 +00004557- Issue #1402: Fix a crash on exit, when another thread is still
4558 running, and if the deallocation of its frames somehow calls the
4559 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004560

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004564 attribute of an empty cell object.
4565
Georg Brandl3ee81df2008-05-17 18:14:43 +00004566- Issue #1460: The utf-7 incremental decoder did not accept truncated
4567 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004568
Georg Brandl3ee81df2008-05-17 18:14:43 +00004569- Patch #1739468: Directories and zipfiles containing a __main__.py
4570 file can now be directly executed by passing their name to the
4571 interpreter. The directory/zipfile is automatically inserted as the
4572 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004573
Georg Brandl3ee81df2008-05-17 18:14:43 +00004574- Issue #1265: Fix a problem with sys.settrace, if the tracing
4575 function uses a generator expression when at the same time the
4576 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004577
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004578- sets and frozensets now have an isdisjoint() method.
4579
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004580- optimize the performance of builtin.sum().
4581
Neal Norwitz44f326e2007-10-05 05:29:17 +00004582- Fix warnings found by the new version of the Coverity checker.
4583
Georg Brandl21e99f42010-03-07 15:23:59 +00004584- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004585 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4586 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004587
Georg Brandl3ee81df2008-05-17 18:14:43 +00004588- Issue #1686386: Tuple's tp_repr did not take into account the
4589 possibility of having a self-referential tuple, which is possible
4590 from C code. Nor did object's tp_str consider that a type's tp_str
4591 could do something that could lead to an inifinite recursion.
4592 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4593 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004594
Georg Brandl3ee81df2008-05-17 18:14:43 +00004595- Issue #1164: It was possible to trigger deadlock when using the
4596 'print' statement to write to a file since the GIL was not released
4597 as needed. Now PyObject_Print() does the right thing along with
4598 various tp_print implementations of the built-in types and those in
4599 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004600
Georg Brandl3ee81df2008-05-17 18:14:43 +00004601- Issue #1147: Exceptions were directly allowing string exceptions in
4602 their throw() method even though string exceptions no longer
4603 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004604
Georg Brandl3ee81df2008-05-17 18:14:43 +00004605- Issue #1096: Prevent a segfault from getting the repr of a very
4606 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004607
Brett Cannon1e534b52007-09-07 04:18:30 +00004608- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004609 PyObject_Call() never calling back out to Python code to trigger
4610 recursion depth updates/checks. Required the creation of a static
4611 RuntimeError instance in case normalizing an exception put the
4612 recursion check value past its limit. Fixes crashers
4613 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004614
Georg Brandl3ee81df2008-05-17 18:14:43 +00004615- Patch #1031213: Decode source line in SyntaxErrors back to its
4616 original source encoding.

4619 with %G.
4620
Georg Brandl3ee81df2008-05-17 18:14:43 +00004621- Prevent expandtabs() on string and unicode objects from causing a
4622 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00004623

Georg Brandla5ea6892007-06-01 11:33:33 +00004627
Neal Norwitz0ac60192007-05-27 04:08:54 +00004628- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004629 __*__ attributes. (Some already existed, e.g., __doc__ and
4630 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004631
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004632- Add -3 option to the interpreter to warn about features that are
4633 deprecated and will be changed/removed in Python 3.0.
4634
Georg Brandl2134e752007-05-21 20:34:16 +00004635- Patch #1686487: you can now pass any mapping after '**' in function
4636 calls.
4637
Collin Winter62903052007-05-18 23:11:24 +00004638- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004639 "except E as target:". This is to provide forwards compatibility
4640 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004641
Brett Cannon229cee22007-05-05 01:34:02 +00004642- Deprecate BaseException.message as per PEP 352.
4643
Georg Brandl3ee81df2008-05-17 18:14:43 +00004644- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004645 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004646
Vinay Sajip8549ce32007-05-06 17:53:37 +00004647- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004648 setting a plain string, ie don't expand to single letter identifiers.
4649
Raymond Hettinger13936692007-04-11 18:40:58 +00004650- Request #1191699: Slices can now be pickled.
4651
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004652- Request #1193128: str.translate() now allows a None argument for
4653 translations that only remove characters without re-mapping the
4654 remaining characters.
4655
Georg Brandl5cb76c12007-03-21 09:00:39 +00004656- Patch #1682205: a TypeError while unpacking an iterable is no longer
4657 masked by a generic one with the message "unpack non-sequence".
4658
Neal Norwitzaa754b72007-03-21 06:39:48 +00004659- Remove unused file Python/fmod.c.
4660
Guido van Rossum143b5642007-03-23 04:58:42 +00004661- Bug #1683368: The object.__init__() and object.__new__() methods are
4662 now stricter in rejecting excess arguments. The only time when
4663 either allows excess arguments is when it is not overridden and the
4664 other one is. For backwards compatibility, when both are
4665 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004666 warning later). Also, type.__init__() insists on the same signature
4667 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004668
Georg Brandl3ee81df2008-05-17 18:14:43 +00004669- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4670 object to complex using its __complex__() method before falling back
4671 to the __float__() method. Therefore, the functions in the cmath
4672 module now can operate on objects that define a __complex__()
4673 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004674
Georg Brandl3ee81df2008-05-17 18:14:43 +00004675- Patch #1623563: allow __class__ assignment for classes with
4676 __slots__. The old and the new class are still required to have the
4677 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004678
Georg Brandl3ee81df2008-05-17 18:14:43 +00004679- Patch #1642547: Fix an error/crash when encountering syntax errors
4680 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004682- Patch #1462488: Python no longer segfaults when
4683 ``object.__reduce_ex__()`` is called with an object that is faking
4684 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004685
Georg Brandl3ee81df2008-05-17 18:14:43 +00004686- Patch #1680015: Don't modify __slots__ tuple if it contains an
4687 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00004689- Patch #1444529: the builtin compile() now accepts keyword arguments.
4690
Georg Brandl7b9c5552007-03-12 14:30:05 +00004691- Bug #1678647: write a newline after printing an exception in any
4692 case, even when converting the value to a string failed.
4693
Georg Brandl871f1bc2007-03-12 13:17:36 +00004694- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004695 its argument, if it exists. If not, it will work like before. This
4696 allows customizing the output of dir() in the presence of a
4697 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004698
Collin Winter276887b2007-03-12 16:11:39 +00004699- Patch #922167: Python no longer segfaults when faced with infinitely
4700 self-recursive reload() calls (as reported by bug #742342).
4701
Georg Brandl3ee81df2008-05-17 18:14:43 +00004702- Patch #1675981: remove unreachable code from ``type.__new__()``
4703 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004705- Patch #1491866: change the complex() constructor to allow
4706 parthensized forms. This means complex(repr(x)) now works instead of
4707 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004708
Georg Brandlaa2321b2007-03-07 00:40:28 +00004709- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004710 makes the filenames the warning module prints much more sensible
4711 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004712
Georg Brandl49aafc92007-03-07 00:34:46 +00004713- Variant of patch #697613: don't exit the interpreter on a SystemExit
4714 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004715 variable is given, but break into the interactive interpreter just
4716 like on other exceptions or normal program exit.

Georg Brandlfb4b3b72007-04-24 15:27:13 +00005216- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
5217 (as opposed to the command line) will now write file names ending in
5218 ".cpp" too.
5219
Facundo Batistad918a652007-04-24 13:54:38 +00005220- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005221 the client's request was successfully received, understood, and
5222 accepted. Now in these cases no error is raised in urllib (issue
5223 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00005224
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225- Bug #1290505: time.strptime's internal cache of locale information

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005231- Added a timeout parameter to the constructor of other protocols
5232 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5233 work started with create_connection() and timeout in httplib, and
5234 closes patch #723312.
5235
Vinay Sajip8549ce32007-05-06 17:53:37 +00005236- Patch #1676823: Added create_connection() to socket.py, which may be
5237 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00005238 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00005239
Martin v. Löwis0af33882007-03-23 13:27:15 +00005240- Bug #978833: Revert r50844, as it broke _socketobject.dup.
5241

Georg Brandl3ee81df2008-05-17 18:14:43 +00005247- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
5248 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00005249 directories.
5250

5259 initialization failed.
5260
Georg Brandlf66b6032007-03-14 08:27:52 +00005261- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005262 AttributeError instead of an IOError when the server's response
5263 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005264
Georg Brandl3ee81df2008-05-17 18:14:43 +00005265- Patch #957650: "%var%" environment variable references are now
5266 properly expanded in ntpath.expandvars(), also "~user" home
5267 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00005268
Georg Brandl3ee81df2008-05-17 18:14:43 +00005269- Patch #1429539: pdb now correctly initializes the __main__ module
5270 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005271 correctly now.
5272
Georg Brandlbad6f192007-03-13 21:32:56 +00005273- The nonobvious commands.getstatus() function is now deprecated.

5279
Georg Brandl3ee81df2008-05-17 18:14:43 +00005280- Patch #1530482: add pydoc.render_doc() which returns the
5281 documentation for a thing instead of paging it to stdout, which
5282 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00005283
Georg Brandl3ee81df2008-05-17 18:14:43 +00005284- Patch #1533909: the timeit module now accepts callables in addition

5290 parameter which can be set to False to prevent the default
5291 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00005292
Georg Brandl9e6b4702007-03-13 18:15:41 +00005293- Patch #1581073: add a flag to textwrap that prevents the dropping of
5294 whitespace while wrapping.
5295
Georg Brandl92a6bae2007-03-13 17:43:32 +00005296- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005297 are set for invalid interpolation sequences that would lead to
5298 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00005299

5312
Georg Brandl94fe3f52007-03-13 09:32:11 +00005313- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00005314 field names in its exception message if you try to write a record
5315 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00005333

5341 returned string up to the first NUL character.

5352
Georg Brandl3ee81df2008-05-17 18:14:43 +00005353- unittest now verifies more of its assumptions. In particular,
5354 TestCase and TestSuite subclasses (not instances) are no longer
5355 accepted in TestSuite.addTest(). This should cause no
5356 incompatibility since it never made sense with ordinary subclasses
5357 -- the failure just occurred later, with a more cumbersome
5358 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00005359

5367 given a unicode argument and os.listdir() returns unicode filenames.
5368
Georg Brandl3ee81df2008-05-17 18:14:43 +00005369- Patch #1673619: setup.py identifies extension modules it doesn't
5370 know how to build and those it knows how to build but that fail to
5371 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005747 time so that opening a database previously created with the DB_DUP
5748 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5749 opens. Specifically: dictionary assignment to a DB object will
5750 replace all values for a given key when the database allows
5751 duplicate values. DB users should use DB.put(k, v) when they want
5752 to store duplicates; not DB[k] = v.

5759 characters with ASCII value less than 32. Also, it correctly quotes
5760 dots only if they occur on a single line, as opposed to the previous
5761 behavior of quoting dots if they are the second character of any
5762 line.
