Ezio Melottiab2eb0e2010-06-05 19:21:32 +000057- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
58 start byte and the continuation byte(s) are now considered invalid, instead
59 of the number of bytes specified by the start byte.
60 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
61 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
62 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
63 Previous versions returned a single u'\ufffd'.
64
Mark Dickinson23f0d6b2010-06-05 11:52:24 +000065- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +000066 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
67 arises from the "Overriding __eq__ blocks inheritance ..." warning
68 when turned into an exception: in this case the exception simply
69 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +000070
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +000071- Issue #8748: Fix two issues with comparisons between complex and integer
72 objects. (1) The comparison could incorrectly return True in some cases
73 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
74 (2) The comparison raised an OverflowError for large integers, leading
75 to unpredictable exceptions when combining integers and complex objects
76 in sets or dicts.
77
Mark Dickinson81336372010-05-30 12:12:25 +000078- Issue #5211: Implicit coercion for the complex type is now completely
79 removed. (Coercion for arithmetic operations was already removed in 2.7
80 alpha 4, but coercion for rich comparisons was accidentally left in.)
81
Victor Stinnerc49dfcc2010-05-25 22:30:32 +000082- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
83 and error handler, instead of writing to the C stderr file in utf-8
84
Georg Brandlfee0f442010-05-22 21:26:21 +000085- Issue #7902: When using explicit relative import syntax, don't try implicit
86 relative import semantics.

98 of the interpreter to set sys.argv without also modifying sys.path. This
99 helps fix `CVE-2008-5983

444
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000445- Issue #8329: Don't return the same lists from select.select when no fds are

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

Georg Brandlfee0f442010-05-22 21:26:21 +0000524 argument `-` which tells it to read files to compile from stdin. Each line is
525 read on demand and the named file is compiled immediately. (Original patch by
526 Piotr Ożarowski).

537 makes Fraction <=> complex comparisons consistent with int <=> complex, float
538 <=> complex, and complex <=> complex comparisons.

647 the set of integer codes for which it was used differed between native packing
648 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000946 file position when calling `truncate()`. It would previously change the file
947 position to the given argument, which goes against the tradition of

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

1045-----------------
1046
Georg Brandlba83f822010-03-14 09:50:54 +00001047- The ``__complex__()`` method is now looked up on the class of instances to
1048 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001050- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1051 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1052
Mark Dickinson1b34d252010-01-01 17:27:30 +00001053- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001054 DeprecationWarning when passed a float argument where an integer was expected.
1055 These functions and methods now raise TypeError instead. The majority of the
1056 effects of this change are in the extension modules, but some core functions
1057 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1058 and many unicode/str methods.

1070
Georg Brandlba83f822010-03-14 09:50:54 +00001071- Issue #1811: Improve accuracy and cross-platform consistency for true division
1072 of integers: the result of a/b is now correctly rounded for ints a and b (at
1073 least on IEEE 754 platforms), and in particular does not depend on the
1074 internal representation of a long.

1082
Georg Brandlba83f822010-03-14 09:50:54 +00001083 These executables now work properly with the arch(1) command: ``arch -ppc
1084 python`` will start a universal binary version of python in PPC mode (unlike
1085 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001108 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

1242 decimal string that's guaranteed to round back to x under correct rounding
1243 (with round-half-to-even rounding mode). Previously it gave a string based on
1244 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1245 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1246 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001248- Issue #7117: On almost all platforms: float-to-string and string-to-float
1249 conversions within Python are now correctly rounded. Places these conversions
1250 occur include: str for floats and complex numbers; the float and complex
1251 constructors; old-style and new-style numeric formatting; serialization and
1252 deserialization of floats and complex numbers using marshal, pickle and json;
1253 parsing of float and imaginary literals in Python code; Decimal-to-float
1254 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001255
Georg Brandlba83f822010-03-14 09:50:54 +00001256 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1257 providing correctly-rounded strtod and dtoa C functions. This code is
1258 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1259 the C compiler. There may be a small number of platforms on which correct
1260 operation of this code cannot be guaranteed, so the code is not used: notably,
1261 this applies to platforms where the C double format is not IEEE 754 binary64,
1262 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1263 and Python's configure script is unable to determine how to change the FPU
1264 precision. On these platforms conversions use the platform strtod and dtoa,
1265 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001267- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1268 uses the correctly-rounded string <-> float conversions described above (when
1269 available), and so produces correctly rounded results that will display nicely
1270 under the float repr. There are two related small changes: (1) round now
1271 accepts any class with an ``__index__()`` method for its second argument (but
1272 no longer accepts floats for the second argument), and (2) an excessively
1273 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1274 raises an exception.

2857 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2858 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003057- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3058 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3059 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3060 ``printf`` function, whereas PyString_FromFormat has an independent
3061 implementation and uses "%zd" on all platforms for size_t values.
3062 This makes a difference on win64, where ``printf`` needs "%Id" to display

3158 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3159 for catch_warnings() also led to an improvement in the raising of a
3160 DeprecationWarning related to warnings.warn_explicit().
3161

3184
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003185- Issue #2975: When compiling several extension modules with Visual Studio 2008
3186 from the same python interpreter, some environment variables would grow
3187 without limit.
3188

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003226What's New in Python 2.6 beta 3?
3227================================
3228
Barry Warsaw07a4a382008-08-21 01:15:08 +00003229*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003230
3231Core and Builtins
3232-----------------
3233
Guido van Rossumf8402962008-08-20 15:01:50 +00003234- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3235 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3236 extensions do not automatically benefit from the class attribute
3237 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3238 to their tp_flags field if they care. This is a backwards
3239 compatibility feature; in 3.0, all types will use the cache by
3240 default.
3241
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003242- Keyword arguments can now follow starred arguments. (``f(a, *args,
3243 keyword=23)`` is now valid syntax.)
3244
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003245- ctypes function pointers that are COM methods have a boolean True
3246 value again.
3247
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003248- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3249 by denying s# to parse objects that have a releasebuffer procedure,
3250 and introducing s*.
3251
Georg Brandl1e13ea92008-08-11 09:07:59 +00003252- Issue #3537: Fix an assertion failure when an empty but presized dict
3253 object was stored in the freelist.
3254
Mark Dickinsonb6467572008-08-04 21:30:09 +00003255- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3256 ValueError consistently across platforms.
3257
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003258- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3259 (64bit Unix, for example), unichr() would truncate its argument and return
3260 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3261
Neal Norwitze7d8be82008-07-31 17:17:14 +00003262- Apply security patches from Apple.
3263
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003264- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3265 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3266
Antoine Pitrou92f82162008-07-25 22:22:08 +00003267- Issue #1819: function calls with several named parameters are now on
3268 average 35% faster (as measured by pybench).
3269
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003270- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3271 the python debugger steps into a class statement: the free variables (local
3272 variables defined in an outer scope) would be deleted from the outer scope.
3273
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003274- Issue #2620: Overflow checking when allocating or reallocating memory
3275 was not always being done properly in some python types and extension
3276 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3277 all been updated to perform better checks and places in the code that
3278 would previously leak memory on the error path when such an allocation
3279 failed have been fixed.

3283
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003284- Issue #3612: Added some missing basic types in ctypes.wintypes.
3285
Benjamin Petersone977ad42008-08-20 01:42:01 +00003286- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3287 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3288
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003289- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3290 version reported by these tools does not necessarily follow the python
3291 version numbering scheme, so the module is less strict when parsing it.
3292
Nick Coghlanf70385a2008-08-18 12:42:46 +00003293- Issue #2235: Added Py3k warnings for types which will become unhashable
3294 under the stricter __hash__ inheritance rules in 3.0. Several types
3295 which did not meet the rules for hash invariants and were already
3296 unhashable in 3.0 have now been explicitly flagged as unhashable in
3297 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3298 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3299
Brett Cannon88f801d2008-08-18 00:46:22 +00003300- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3301 imported into the module but exposed as part of the module's API.
3302
Brett Cannon7b96f072008-08-18 00:41:11 +00003303- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3304
Brett Cannon46225e72008-08-18 00:36:52 +00003305- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003307- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3308
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003309- Issue #3575: Incremental decoder's decode function now takes bytearray
3310 by using 's*' instead of 't#'.
3311
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003312- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003313 fails unicode conversion on 2nd parameter. (windows only)
3314
Facundo Batista94f243a2008-08-17 03:38:39 +00003315- Issue 2464. urllib2 now supports a malformation in the URL received
3316 in a redirect.
3317
Brett Cannonabe423e2008-08-16 21:47:07 +00003318- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003319 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003320
Facundo Batistaeb90b782008-08-16 14:44:07 +00003321- Issue #2776: fixed small issue when handling an URL with double slash
3322 after a 302 response in the case of not going through a proxy.
3323
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003324- Issue #2676: in the email package, content-type parsing was hanging on
3325 pathological input because of quadratic or exponential behaviour of a
3326 regular expression.
3327
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003328- Issue #3476: binary buffered reading through the new "io" library is now
3329 thread-safe.
3330
Brett Cannonbf3157b2008-08-14 05:00:03 +00003331- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3332 since mimetools itself is deprecated. Because modules are cached, all
3333 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3334
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003335- Issue #3134: shutil referenced undefined WindowsError symbol.
3336
Robert Schuppenies14646332008-08-10 11:01:53 +00003337- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3338 menu entries were not deleted.
3339
Brett Cannon83e81842008-08-09 23:30:55 +00003340- Copied the implementation of reduce() to _functools.reduce() to have a
3341 version that did not raise a DeprecationWarning under -3.
3342
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003343- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3344 a MemoryError rather than silently stop the iteration.
3345
Guido van Rossum59ce9012008-08-09 14:55:34 +00003346- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3347 to _sre.compile() will now be rejected. This should not affect anybody
3348 since the re.compile() function never generates invalid re-bytecode.
3349
Skip Montanaroa032bf42008-08-08 22:52:51 +00003350- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3351 upon first access it can be automatically initialized from the csv file if
3352 it wasn't initialized during instantiation.
3353
Brett Cannon3aa2a492008-08-06 22:28:09 +00003354- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3355 the reload() built-in has been removed.
3356
Brett Cannon7e30b672008-08-04 21:52:25 +00003357- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003358 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003369 asking for a specific length. This problem only affected files opened
3370 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003371

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003420What's New in Python 2.6 beta 2?
3421================================
3422
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003423*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003425Core and Builtins
3426-----------------
3427
Georg Brandl3e483f62008-07-16 22:57:41 +00003428- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3429 its methods now allow for items objects that can be converted to
3430 an integer using operator.index().
3431
Mark Dickinson64b7e502008-07-16 09:40:03 +00003432- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3433 produced a ValueError instead of giving the correct float.
3434
Eric Smitha5fa5a22008-07-16 00:11:49 +00003435- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3436 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3437
Mark Dickinson7103aa42008-07-15 19:08:33 +00003438- Issue #3008: the float type has a new instance method 'float.hex'
3439 and a new class method 'float.fromhex' to convert floating-point
3440 numbers to and from hexadecimal strings, respectively.
3441
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003442- Issue #2235: __hash__ is once again inherited by default. To allow
3443 collections.Hashable to remain meaningful in the presence of the
3444 default hash implementation (object.__hash__), it is now possible
3445 to explicit block inheritance of hash by setting __hash__=None at
3446 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3447 level.
3448
Nick Coghlanb028f502008-07-13 14:52:36 +00003449- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3450 the parent module cannot be found while performing an absolute import.
3451 This means that an incorrectly defined __package__ attribute will
3452 now only prevent relative imports in that module rather than causing
3453 all imports from that module to fail.
3454
Nick Coghlan14ff9942008-07-08 14:21:42 +00003455- Issue #2517: Allow unicode messages in Exceptions again by correctly
3456 bypassing the instance dictionary when looking up __unicode__ on

3460 set to a custom object whose write() method happens to install
3461 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003463- Issue #3088: Corrected a race condition in classes derived from
3464 threading.local: the first member set by a thread could be saved in
3465 another thread's dictionary.
3466
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003467- Issue #3004: Minor change to slice.indices(): the start and stop
3468 arguments are now treated identically, making the behaviour easier
3469 to describe and understand. For example, slice(None, -10,
3470 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3471 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3472 10, -1).
3473
Georg Brandl278fc502008-07-19 12:46:12 +00003474- Issue #3219: Calling a function with repeated keyword arguments,
3475 f(a=2, a=23), would not cause a syntax error. This was a regression
3476 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003477
Georg Brandl278fc502008-07-19 12:46:12 +00003478- Issue #2862: Make int and float freelist management consistent with
3479 other freelists. Changes their CompactFreeList apis into
3480 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003485- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3486 api functions without holding the GIL, which could lead to a fatal
3487 error when they failed.
3488
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003489- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003514- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3515 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003516 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003517 content-length. The problem had been corrected in the 2.4 branch, but never
3518 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003533- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3534 handling is now the same as that of other special attributes like __name__).
3535
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003536- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00003988- Issue #1631171: Re-implement the 'warnings' module in C (the
3989 original Python code has been kept as backup). This will allow for
3990 using the 'warning's machinery in such places as the parser where
3991 use of pure Python code is not possible. Both the ``showarning()``
3992 and ``formatwarning()`` gain an optional 'line' argument which is
3993 not called by default for backwards-compatibility reasons. Setting
3994 ``warnings.showwarning()`` to an implementation that lacks support
3995 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004058- Issue #2550: The approach used by client/server code for obtaining
4059 ports to listen on in network-oriented tests has been refined in an
4060 effort to facilitate running multiple instances of the entire
4061 regression test suite in parallel without issue.
4062 test_support.bind_port() has been fixed such that it will always
4063 return a unique port -- which wasn't always the case with the
4064 previous implementation, especially if socket options had been set
4065 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4066 new implementation of bind_port() will actually raise an exception
4067 if it is passed an AF_INET/SOCK_STREAM socket with either the
4068 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4069 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4070 the socket it's been passed. This currently only applies to
4071 Windows. This option prevents any other sockets from binding to the
4072 host/port we've bound to, thus removing the possibility of the
4073 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4074 when a second SOCK_STREAM socket binds and accepts to a host/port
4075 that's already been bound by another socket. The optional preferred
4076 port parameter to bind_port() has been removed. Under no
4077 circumstances should tests be hard coding ports!
4078
4079 test_support.find_unused_port() has also been introduced, which will
4080 pass a temporary socket object to bind_port() in order to obtain an
4081 unused port. The temporary socket object is then closed and
4082 deleted, and the port is returned. This method should only be used
4083 for obtaining an unused port in order to pass to an external program
4084 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4085 a parameter to a server-oriented class that doesn't give you direct
4086 access to the underlying socket used.
4087
4088 Finally, test_support.HOST has been introduced, which should be used
4089 for the host argument of any relevant socket calls (i.e. bind and
4090 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004091
4092 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004093 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004094 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4095 test_asynchat and test_socket_ssl.
4096
Georg Brandl3ee81df2008-05-17 18:14:43 +00004097 It is now possible for multiple instances of the regression test
4098 suite to run in parallel without issue.

4365-----------------
4366
Fred Drakea8ee94b2008-03-01 02:45:07 +00004367- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004368 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00004373
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004374- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004375 issue 215555 for a discussion.
4376
Eric Smitha73fbe72008-02-23 03:09:44 +00004377- Added the future_builtins module, which contains hex() and oct().
4378 These are the PEP 3127 version of these functions, designed to be
4379 compatible with the hex() and oct() builtins from Python 3.0. They
4380 differ slightly in their output formats from the existing, unchanged
4381 Python 2.6 builtins. The expected usage of the future_builtins
4382 module is:
4383 from future_builtins import hex, oct
4384
Eric Smith7ef40bf2008-02-20 23:34:22 +00004385- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4386 exponents for exponents with absolute value < 100. Follows C99
4387 standard. This is a change on Windows, which would use 3 digits.
4388 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4389 so that any alterations it does to the resulting string will be
4390 available in stringlib/formatter.h (for float.__format__).
4391
Eric Smith5a3c1352008-02-19 13:21:56 +00004392- Implemented PEP 3101, Advanced String Formatting. This adds a new
4393 builtin format(); a format() method for str and unicode; a
4394 __format__() method to object, str, unicode, int, long, float, and
4395 datetime; the class string.Formatter; and the C API
4396 PyObject_Format().
4397
Georg Brandl3ee81df2008-05-17 18:14:43 +00004398- Fixed several potential crashes, all caused by specially crafted
4399 __del__ methods exploiting objects in temporarily inconsistent
4400 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004401
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004402- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004403 prevent a possible crash: an Abstract Base Class would try to access
4404 a slot on a registered virtual subclass.

4411 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004412
Georg Brandl3ee81df2008-05-17 18:14:43 +00004413- Issue #2045: Fix an infinite recursion triggered when printing a
4414 subclass of collections.defaultdict, if its default_factory is set
4415 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004416
Christian Heimesf75dbef2008-02-08 00:11:31 +00004417- Fixed a minor memory leak in dictobject.c. The content of the free
4418 list was not freed on interpreter shutdown.
4419
Georg Brandl21e99f42010-03-07 15:23:59 +00004420- Limit free list of method and built-in function objects to 256

4424 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004425 to compact the internal free lists of pre-allocted ints and floats.
4426
Georg Brandl3ee81df2008-05-17 18:14:43 +00004427- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4428 calls. Python expected the return type int but the fork familie
4429 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004443- Patch #1473257: generator objects gain a gi_code attribute. This is
4444 the same object as the func_code attribute of the function that
4445 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004446
Georg Brandl3ee81df2008-05-17 18:14:43 +00004447- Issue #1920: "while 0" statements were completely removed by the
4448 compiler, even in the presence of an "else" clause, which is
4449 supposed to be run when the condition is false. Now the compiler
4450 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004451

4459
Georg Brandl3ee81df2008-05-17 18:14:43 +00004460- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004461 several extension methods and modules do not work without unicode

Georg Brandl6caad7d2008-01-26 14:19:22 +00004469- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004470 added.
4471
Christian Heimesc94e2b52008-01-14 04:13:37 +00004472- sys.float_info / PyFloat_GetInfo: The floating point information
4473 object was converted from a dict to a specialized structseq object.
4474
Georg Brandl3ee81df2008-05-17 18:14:43 +00004475- Patch #1816: Added sys.flags structseq. It exposes the status of
4476 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004477
Georg Brandl3ee81df2008-05-17 18:14:43 +00004478- Objects/structseq.c: Implemented new structseq representation. The
4479 patch makes structseqs (e.g. the return value of os.stat) more
4480 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004481
Georg Brandl3ee81df2008-05-17 18:14:43 +00004482- Patch #1700288: added a type attribute cache that caches method
4483 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004484
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004485- Bug #1776: __import__() no longer accepts filenames on any platform.
4486 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004487
Georg Brandlaed6c662008-01-07 17:25:53 +00004488- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4489
Georg Brandl3ee81df2008-05-17 18:14:43 +00004490- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4491 envvar and sys.dont_write_bytecode attribute. All these can be set
4492 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004493
Georg Brandl3ee81df2008-05-17 18:14:43 +00004494- Improve some exception messages when Windows fails to load an
4495 extension module. Now we get for example '%1 is not a valid Win32
4496 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004497

Georg Brandl3ee81df2008-05-17 18:14:43 +00004500- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4501 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004502
Christian Heimes0a8143f2007-12-18 23:22:54 +00004503- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004504 and INF. float("nan"), float("inf") and float("-inf") now work on
4505 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004506
Georg Brandl3ee81df2008-05-17 18:14:43 +00004507- Compiler now generates simpler and faster code for dictionary
4508 literals. The oparg for BUILD_MAP now indicates an estimated
4509 dictionary size. There is a new opcode, STORE_MAP, for adding
4510 entries to the dictionary.

4522
Nick Coghlanef01d822007-12-03 12:55:17 +00004523- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00004539- Patch #1739468: Directories and zipfiles containing a __main__.py
4540 file can now be directly executed by passing their name to the
4541 interpreter. The directory/zipfile is automatically inserted as the
4542 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004543
Georg Brandl3ee81df2008-05-17 18:14:43 +00004544- Issue #1265: Fix a problem with sys.settrace, if the tracing
4545 function uses a generator expression when at the same time the
4546 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004547
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004548- sets and frozensets now have an isdisjoint() method.
4549

4551
Neal Norwitz44f326e2007-10-05 05:29:17 +00004552- Fix warnings found by the new version of the Coverity checker.
4553
Georg Brandl21e99f42010-03-07 15:23:59 +00004554- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004555 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4556 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004557
Georg Brandl3ee81df2008-05-17 18:14:43 +00004558- Issue #1686386: Tuple's tp_repr did not take into account the
4559 possibility of having a self-referential tuple, which is possible
4560 from C code. Nor did object's tp_str consider that a type's tp_str
4561 could do something that could lead to an inifinite recursion.
4562 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4563 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004564
Georg Brandl3ee81df2008-05-17 18:14:43 +00004565- Issue #1164: It was possible to trigger deadlock when using the
4566 'print' statement to write to a file since the GIL was not released
4567 as needed. Now PyObject_Print() does the right thing along with
4568 various tp_print implementations of the built-in types and those in
4569 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004570
Georg Brandl3ee81df2008-05-17 18:14:43 +00004571- Issue #1147: Exceptions were directly allowing string exceptions in
4572 their throw() method even though string exceptions no longer
4573 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004574
Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- Issue #1096: Prevent a segfault from getting the repr of a very
4576 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004577
Brett Cannon1e534b52007-09-07 04:18:30 +00004578- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004579 PyObject_Call() never calling back out to Python code to trigger
4580 recursion depth updates/checks. Required the creation of a static
4581 RuntimeError instance in case normalizing an exception put the
4582 recursion check value past its limit. Fixes crashers
4583 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004584

Neal Norwitz0ac60192007-05-27 04:08:54 +00004598- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004599 __*__ attributes. (Some already existed, e.g., __doc__ and
4600 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004601
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004602- Add -3 option to the interpreter to warn about features that are
4603 deprecated and will be changed/removed in Python 3.0.
4604
Georg Brandl2134e752007-05-21 20:34:16 +00004605- Patch #1686487: you can now pass any mapping after '**' in function
4606 calls.
4607
Collin Winter62903052007-05-18 23:11:24 +00004608- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004609 "except E as target:". This is to provide forwards compatibility
4610 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004611
Brett Cannon229cee22007-05-05 01:34:02 +00004612- Deprecate BaseException.message as per PEP 352.
4613
Georg Brandl3ee81df2008-05-17 18:14:43 +00004614- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004615 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004616
Vinay Sajip8549ce32007-05-06 17:53:37 +00004617- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004618 setting a plain string, ie don't expand to single letter identifiers.
4619
Raymond Hettinger13936692007-04-11 18:40:58 +00004620- Request #1191699: Slices can now be pickled.
4621
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004622- Request #1193128: str.translate() now allows a None argument for
4623 translations that only remove characters without re-mapping the
4624 remaining characters.
4625
Georg Brandl5cb76c12007-03-21 09:00:39 +00004626- Patch #1682205: a TypeError while unpacking an iterable is no longer
4627 masked by a generic one with the message "unpack non-sequence".
4628
Neal Norwitzaa754b72007-03-21 06:39:48 +00004629- Remove unused file Python/fmod.c.
4630
Guido van Rossum143b5642007-03-23 04:58:42 +00004631- Bug #1683368: The object.__init__() and object.__new__() methods are
4632 now stricter in rejecting excess arguments. The only time when
4633 either allows excess arguments is when it is not overridden and the
4634 other one is. For backwards compatibility, when both are
4635 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004636 warning later). Also, type.__init__() insists on the same signature
4637 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004638
Georg Brandl3ee81df2008-05-17 18:14:43 +00004639- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4640 object to complex using its __complex__() method before falling back
4641 to the __float__() method. Therefore, the functions in the cmath
4642 module now can operate on objects that define a __complex__()
4643 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004644
Georg Brandl3ee81df2008-05-17 18:14:43 +00004645- Patch #1623563: allow __class__ assignment for classes with
4646 __slots__. The old and the new class are still required to have the
4647 same slot names.

4653 ``object.__reduce_ex__()`` is called with an object that is faking
4654 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004655
Georg Brandl3ee81df2008-05-17 18:14:43 +00004656- Patch #1680015: Don't modify __slots__ tuple if it contains an

4660
Georg Brandl7b9c5552007-03-12 14:30:05 +00004661- Bug #1678647: write a newline after printing an exception in any
4662 case, even when converting the value to a string failed.
4663
Georg Brandl871f1bc2007-03-12 13:17:36 +00004664- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004665 its argument, if it exists. If not, it will work like before. This
4666 allows customizing the output of dir() in the presence of a
4667 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004669- Patch #922167: Python no longer segfaults when faced with infinitely
4670 self-recursive reload() calls (as reported by bug #742342).
4671
Georg Brandl3ee81df2008-05-17 18:14:43 +00004672- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004675- Patch #1491866: change the complex() constructor to allow
4676 parthensized forms. This means complex(repr(x)) now works instead of
4677 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004678
Georg Brandlaa2321b2007-03-07 00:40:28 +00004679- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004680 makes the filenames the warning module prints much more sensible
4681 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004682
Georg Brandl49aafc92007-03-07 00:34:46 +00004683- Variant of patch #697613: don't exit the interpreter on a SystemExit
4684 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004685 variable is given, but break into the interactive interpreter just
4686 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004694- Patch #1674228: when assigning a slice (old-style), check for the
4695 sq_ass_slice instead of the sq_slice slot.
4696
Georg Brandl3ee81df2008-05-17 18:14:43 +00004697- When printing an unraisable error, don't print exceptions. before
4698 the name. This duplicates the behavior whening normally printing
4699 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005201- Added a timeout parameter to the constructor of other protocols
5202 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5203 work started with create_connection() and timeout in httplib, and
5204 closes patch #723312.
5205

Georg Brandl3ee81df2008-05-17 18:14:43 +00005232 AttributeError instead of an IOError when the server's response
5233 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005234

Georg Brandl3ee81df2008-05-17 18:14:43 +00005239- Patch #1429539: pdb now correctly initializes the __main__ module
5240 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005241 correctly now.
5242

Georg Brandl3ee81df2008-05-17 18:14:43 +00005250- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00005263- Patch #1581073: add a flag to textwrap that prevents the dropping of
5264 whitespace while wrapping.
5265
Georg Brandl92a6bae2007-03-13 17:43:32 +00005266- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005267 are set for invalid interpolation sequences that would lead to
5268 errors on reading back those values.

5311 returned string up to the first NUL character.

5322
Georg Brandl3ee81df2008-05-17 18:14:43 +00005323- unittest now verifies more of its assumptions. In particular,
5324 TestCase and TestSuite subclasses (not instances) are no longer
5325 accepted in TestSuite.addTest(). This should cause no
5326 incompatibility since it never made sense with ordinary subclasses
5327 -- the failure just occurred later, with a more cumbersome
5328 exception.

5338
Georg Brandl3ee81df2008-05-17 18:14:43 +00005339- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00005717 time so that opening a database previously created with the DB_DUP
5718 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5719 opens. Specifically: dictionary assignment to a DB object will
5720 replace all values for a given key when the database allows
5721 duplicate values. DB users should use DB.put(k, v) when they want
5722 to store duplicates; not DB[k] = v.

5729 characters with ASCII value less than 32. Also, it correctly quotes
5730 dots only if they occur on a single line, as opposed to the previous
5731 behavior of quoting dots if they are the second character of any
5732 line.
