Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000935- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
936 start byte and the continuation byte(s) are now considered invalid, instead
937 of the number of bytes specified by the start byte.
938 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
939 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
940 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
941 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000943- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000944 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
945 arises from the "Overriding __eq__ blocks inheritance ..." warning
946 when turned into an exception: in this case the exception simply
947 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000949- Issue #8748: Fix two issues with comparisons between complex and integer
950 objects. (1) The comparison could incorrectly return True in some cases
951 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
952 (2) The comparison raised an OverflowError for large integers, leading
953 to unpredictable exceptions when combining integers and complex objects
954 in sets or dicts.
955
Mark Dickinson81336372010-05-30 12:12:25 +0000956- Issue #5211: Implicit coercion for the complex type is now completely
957 removed. (Coercion for arithmetic operations was already removed in 2.7
958 alpha 4, but coercion for rich comparisons was accidentally left in.)
959
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000960- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
961 and error handler, instead of writing to the C stderr file in utf-8
962
Georg Brandlfee0f442010-05-22 21:26:21 +0000963- Issue #7902: When using explicit relative import syntax, don't try implicit

1094 non-float non-integer argument is now converted to an integer (if possible)
1095 using its __int__ method. Previously, only small arguments were treated this
1096 way; larger arguments (those whose __int__ was outside the range of a C long)

1324 changed.
1325
Georg Brandlfee0f442010-05-22 21:26:21 +00001326- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001327 on 64-bit machines. The shift count for either left or right shift is

Georg Brandlfee0f442010-05-22 21:26:21 +00001336- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1337 with a non-empty format string. This is an effort to future-proof user
1338 code. If a derived class does not currently implement __format__ but later
1339 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001340 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001341 Python 3.3 and it will be an error in Python 3.4.

1392 InvalidOperation instead of returning False. (Comparisons involving a quiet
1393 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal

1414 Fractions instance now raise TypeError instead of returning True/False. This
1415 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1416 <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001515- Issue #8300: When passing a non-integer argument to struct.pack with any
1516 integer format code, struct.pack first attempts to convert the non-integer

1518 TypeError it goes on to try the __int__ method, as described below.
1519
Georg Brandlba83f822010-03-14 09:50:54 +00001520- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1521 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1522 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001523 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1524 inconsistent: __int__ was used for some integer codes but not for others, and
1525 the set of integer codes for which it was used differed between native packing
1526 and standard packing.)

R. David Murrayf28fd242010-02-23 00:24:49 +00001736 is run with the -OO flag. Tests requiring docstrings are skipped.
1737
Georg Brandlba83f822010-03-14 09:50:54 +00001738- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is

Georg Brandlba83f822010-03-14 09:50:54 +00001773- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1774 and add the additional members returned in an OSVERSIONINFOEX structure. The
1775 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001778- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1779 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1780 returning NULL. The macro now returns a statically allocated empty string
1781 instead.

1791 strings,
1792 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1793 numeric strings corresponding to subnormal values,
1794 (3) a memory leak for some values large enough to cause overflow, and
1795 (4) a number of flaws that could lead to incorrectly rounded results.

1814
Georg Brandlba83f822010-03-14 09:50:54 +00001815- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

Antoine Pitroud840e512010-02-04 20:20:18 +00001826- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001827 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001828 Also, raise ValueError rather than TypeError when an unknown TIPC address
1829 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001833- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001834 file position when calling `truncate()`. It would previously change the file
1835 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001836 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1837
Georg Brandlba83f822010-03-14 09:50:54 +00001838- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1839 class used to represent files stored inside an archive. The new
1840 implementation is significantly faster and can be wrapped in a
1841 ``io.BufferedReader`` object for more speedups. It also solves an issue
1842 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1843 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001853- Issue #7748: Since unicode values are supported for some metadata options in
1854 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1855 encoded string for them. This ensures that the upload and register commands
1856 send the correct values to PyPI without any error.

1941 These functions and methods now raise TypeError instead. The majority of the
1942 effects of this change are in the extension modules, but some core functions
1943 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1944 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002127- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2128 decimal string that's guaranteed to round back to x under correct rounding
2129 (with round-half-to-even rounding mode). Previously it gave a string based on
2130 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2131 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2132 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002134- Issue #7117: On almost all platforms: float-to-string and string-to-float
2135 conversions within Python are now correctly rounded. Places these conversions
2136 occur include: str for floats and complex numbers; the float and complex
2137 constructors; old-style and new-style numeric formatting; serialization and
2138 deserialization of floats and complex numbers using marshal, pickle and json;
2139 parsing of float and imaginary literals in Python code; Decimal-to-float
2140 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002141
Georg Brandlba83f822010-03-14 09:50:54 +00002142 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2143 providing correctly-rounded strtod and dtoa C functions. This code is
2144 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2145 the C compiler. There may be a small number of platforms on which correct
2146 operation of this code cannot be guaranteed, so the code is not used: notably,
2147 this applies to platforms where the C double format is not IEEE 754 binary64,
2148 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2149 and Python's configure script is unable to determine how to change the FPU
2150 precision. On these platforms conversions use the platform strtod and dtoa,
2151 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002153- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2154 uses the correctly-rounded string <-> float conversions described above (when
2155 available), and so produces correctly rounded results that will display nicely
2156 under the float repr. There are two related small changes: (1) round now
2157 accepts any class with an ``__index__()`` method for its second argument (but
2158 no longer accepts floats for the second argument), and (2) an excessively
2159 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2160 raises an exception.

Antoine Pitrou0668c622008-08-26 22:42:08 +00003969 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3970 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3971 when given a tuple of classes as second argument, were looking up
3972 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3973 type object.
3974

3984 function 'stringlib_contains_obj'.
3985
Benjamin Peterson712ee922008-08-24 18:10:20 +00003986- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

Brett Cannon1eaf0742008-09-02 01:25:16 +00004044 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4045 for catch_warnings() also led to an improvement in the raising of a
4046 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004112What's New in Python 2.6 beta 3?
4113================================
4114
Barry Warsaw07a4a382008-08-21 01:15:08 +00004115*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004116
4117Core and Builtins
4118-----------------
4119
Guido van Rossumf8402962008-08-20 15:01:50 +00004120- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4121 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4122 extensions do not automatically benefit from the class attribute
4123 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4124 to their tp_flags field if they care. This is a backwards
4125 compatibility feature; in 3.0, all types will use the cache by
4126 default.
4127
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004128- Keyword arguments can now follow starred arguments. (``f(a, *args,
4129 keyword=23)`` is now valid syntax.)
4130
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004131- ctypes function pointers that are COM methods have a boolean True
4132 value again.
4133
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004134- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4135 by denying s# to parse objects that have a releasebuffer procedure,
4136 and introducing s*.
4137
Georg Brandl1e13ea92008-08-11 09:07:59 +00004138- Issue #3537: Fix an assertion failure when an empty but presized dict
4139 object was stored in the freelist.
4140
Mark Dickinsonb6467572008-08-04 21:30:09 +00004141- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4142 ValueError consistently across platforms.
4143
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004144- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4145 (64bit Unix, for example), unichr() would truncate its argument and return
4146 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4147
Neal Norwitze7d8be82008-07-31 17:17:14 +00004148- Apply security patches from Apple.
4149
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004150- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4151 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4152
Antoine Pitrou92f82162008-07-25 22:22:08 +00004153- Issue #1819: function calls with several named parameters are now on
4154 average 35% faster (as measured by pybench).
4155
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004156- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4157 the python debugger steps into a class statement: the free variables (local
4158 variables defined in an outer scope) would be deleted from the outer scope.
4159
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004160- Issue #2620: Overflow checking when allocating or reallocating memory
4161 was not always being done properly in some python types and extension
4162 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4163 all been updated to perform better checks and places in the code that
4164 would previously leak memory on the error path when such an allocation
4165 failed have been fixed.

4168-------
4169
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004170- Issue #3612: Added some missing basic types in ctypes.wintypes.
4171
Benjamin Petersone977ad42008-08-20 01:42:01 +00004172- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4173 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4174
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004175- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4176 version reported by these tools does not necessarily follow the python
4177 version numbering scheme, so the module is less strict when parsing it.
4178
Nick Coghlanf70385a2008-08-18 12:42:46 +00004179- Issue #2235: Added Py3k warnings for types which will become unhashable
4180 under the stricter __hash__ inheritance rules in 3.0. Several types
4181 which did not meet the rules for hash invariants and were already
4182 unhashable in 3.0 have now been explicitly flagged as unhashable in
4183 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4184 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4185
Brett Cannon88f801d2008-08-18 00:46:22 +00004186- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4187 imported into the module but exposed as part of the module's API.
4188
Brett Cannon7b96f072008-08-18 00:41:11 +00004189- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4190
Brett Cannon46225e72008-08-18 00:36:52 +00004191- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

4194
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004195- Issue #3575: Incremental decoder's decode function now takes bytearray
4196 by using 's*' instead of 't#'.
4197
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004198- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004199 fails unicode conversion on 2nd parameter. (windows only)
4200
Georg Brandl222e2082010-08-01 22:27:39 +00004201- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004202 in a redirect.
4203
Brett Cannonabe423e2008-08-16 21:47:07 +00004204- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004205 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004206
Facundo Batistaeb90b782008-08-16 14:44:07 +00004207- Issue #2776: fixed small issue when handling an URL with double slash
4208 after a 302 response in the case of not going through a proxy.
4209
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004210- Issue #2676: in the email package, content-type parsing was hanging on
4211 pathological input because of quadratic or exponential behaviour of a
4212 regular expression.
4213
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004214- Issue #3476: binary buffered reading through the new "io" library is now
4215 thread-safe.
4216
Brett Cannonbf3157b2008-08-14 05:00:03 +00004217- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4218 since mimetools itself is deprecated. Because modules are cached, all
4219 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4220
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004221- Issue #3134: shutil referenced undefined WindowsError symbol.
4222
Robert Schuppenies14646332008-08-10 11:01:53 +00004223- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4224 menu entries were not deleted.
4225
Brett Cannon83e81842008-08-09 23:30:55 +00004226- Copied the implementation of reduce() to _functools.reduce() to have a
4227 version that did not raise a DeprecationWarning under -3.
4228
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004229- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4230 a MemoryError rather than silently stop the iteration.
4231
Guido van Rossum59ce9012008-08-09 14:55:34 +00004232- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4233 to _sre.compile() will now be rejected. This should not affect anybody
4234 since the re.compile() function never generates invalid re-bytecode.
4235
Skip Montanaroa032bf42008-08-08 22:52:51 +00004236- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4237 upon first access it can be automatically initialized from the csv file if
4238 it wasn't initialized during instantiation.
4239
Brett Cannon3aa2a492008-08-06 22:28:09 +00004240- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4241 the reload() built-in has been removed.
4242
Brett Cannon7e30b672008-08-04 21:52:25 +00004243- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004244 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4312-----------------
4313
Georg Brandl3e483f62008-07-16 22:57:41 +00004314- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4315 its methods now allow for items objects that can be converted to
4316 an integer using operator.index().
4317
Mark Dickinson64b7e502008-07-16 09:40:03 +00004318- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4319 produced a ValueError instead of giving the correct float.
4320
Eric Smitha5fa5a22008-07-16 00:11:49 +00004321- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4322 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4323
Mark Dickinson7103aa42008-07-15 19:08:33 +00004324- Issue #3008: the float type has a new instance method 'float.hex'
4325 and a new class method 'float.fromhex' to convert floating-point
4326 numbers to and from hexadecimal strings, respectively.
4327
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004328- Issue #2235: __hash__ is once again inherited by default. To allow
4329 collections.Hashable to remain meaningful in the presence of the
4330 default hash implementation (object.__hash__), it is now possible
4331 to explicit block inheritance of hash by setting __hash__=None at
4332 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4333 level.
4334
Nick Coghlanb028f502008-07-13 14:52:36 +00004335- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4336 the parent module cannot be found while performing an absolute import.
4337 This means that an incorrectly defined __package__ attribute will
4338 now only prevent relative imports in that module rather than causing
4339 all imports from that module to fail.
4340
Nick Coghlan14ff9942008-07-08 14:21:42 +00004341- Issue #2517: Allow unicode messages in Exceptions again by correctly

4351 another thread's dictionary.
4352
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004353- Issue #3004: Minor change to slice.indices(): the start and stop
4354 arguments are now treated identically, making the behaviour easier
4355 to describe and understand. For example, slice(None, -10,
4356 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4357 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4358 10, -1).

4401 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004402 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004403 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004419- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4829
Georg Brandl74a1dea2008-05-28 11:21:39 +00004830- Add ``PyType_Modified()`` as a public API to clear the type cache.
4831
4832- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00004833
4834- The PyString functions have been renamed to PyBytes. A batch of
4835 defines were added so that the linker still sees the original
4836 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004874- Issue #1631171: Re-implement the 'warnings' module in C (the
4875 original Python code has been kept as backup). This will allow for
4876 using the 'warning's machinery in such places as the parser where
4877 use of pure Python code is not possible. Both the ``showarning()``
4878 and ``formatwarning()`` gain an optional 'line' argument which is
4879 not called by default for backwards-compatibility reasons. Setting
4880 ``warnings.showwarning()`` to an implementation that lacks support
4881 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004923- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004924 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004944- Issue #2550: The approach used by client/server code for obtaining
4945 ports to listen on in network-oriented tests has been refined in an
4946 effort to facilitate running multiple instances of the entire
4947 regression test suite in parallel without issue.
4948 test_support.bind_port() has been fixed such that it will always
4949 return a unique port -- which wasn't always the case with the
4950 previous implementation, especially if socket options had been set
4951 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4952 new implementation of bind_port() will actually raise an exception
4953 if it is passed an AF_INET/SOCK_STREAM socket with either the
4954 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4955 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4956 the socket it's been passed. This currently only applies to
4957 Windows. This option prevents any other sockets from binding to the
4958 host/port we've bound to, thus removing the possibility of the
4959 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4960 when a second SOCK_STREAM socket binds and accepts to a host/port
4961 that's already been bound by another socket. The optional preferred
4962 port parameter to bind_port() has been removed. Under no
4963 circumstances should tests be hard coding ports!
4964
4965 test_support.find_unused_port() has also been introduced, which will
4966 pass a temporary socket object to bind_port() in order to obtain an
4967 unused port. The temporary socket object is then closed and
4968 deleted, and the port is returned. This method should only be used
4969 for obtaining an unused port in order to pass to an external program
4970 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4971 a parameter to a server-oriented class that doesn't give you direct
4972 access to the underlying socket used.
4973
4974 Finally, test_support.HOST has been introduced, which should be used
4975 for the host argument of any relevant socket calls (i.e. bind and
4976 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004977
4978 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004979 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004980 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4981 test_asynchat and test_socket_ssl.
4982
Georg Brandl3ee81df2008-05-17 18:14:43 +00004983 It is now possible for multiple instances of the regression test
4984 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005263- Added the future_builtins module, which contains hex() and oct().
5264 These are the PEP 3127 version of these functions, designed to be
5265 compatible with the hex() and oct() builtins from Python 3.0. They
5266 differ slightly in their output formats from the existing, unchanged
5267 Python 2.6 builtins. The expected usage of the future_builtins
5268 module is:
5269 from future_builtins import hex, oct
5270
Eric Smith7ef40bf2008-02-20 23:34:22 +00005271- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5272 exponents for exponents with absolute value < 100. Follows C99
5273 standard. This is a change on Windows, which would use 3 digits.
5274 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5275 so that any alterations it does to the resulting string will be
5276 available in stringlib/formatter.h (for float.__format__).
5277
Eric Smith5a3c1352008-02-19 13:21:56 +00005278- Implemented PEP 3101, Advanced String Formatting. This adds a new
5279 builtin format(); a format() method for str and unicode; a
5280 __format__() method to object, str, unicode, int, long, float, and
5281 datetime; the class string.Formatter; and the C API
5282 PyObject_Format().
5283
Georg Brandl3ee81df2008-05-17 18:14:43 +00005284- Fixed several potential crashes, all caused by specially crafted
5285 __del__ methods exploiting objects in temporarily inconsistent
5286 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005287
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005288- Issue #2115: Important speedup in setting __slot__ attributes. Also

5297 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005298
Georg Brandl3ee81df2008-05-17 18:14:43 +00005299- Issue #2045: Fix an infinite recursion triggered when printing a
5300 subclass of collections.defaultdict, if its default_factory is set
5301 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005302
Christian Heimesf75dbef2008-02-08 00:11:31 +00005303- Fixed a minor memory leak in dictobject.c. The content of the free

5312
Georg Brandl3ee81df2008-05-17 18:14:43 +00005313- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5314 calls. Python expected the return type int but the fork familie
5315 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005316

Georg Brandl3ee81df2008-05-17 18:14:43 +00005329- Patch #1473257: generator objects gain a gi_code attribute. This is
5330 the same object as the func_code attribute of the function that
5331 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005332
Georg Brandl3ee81df2008-05-17 18:14:43 +00005333- Issue #1920: "while 0" statements were completely removed by the
5334 compiler, even in the presence of an "else" clause, which is

5336 correctly emits bytecode for the "else" suite.

5340 borrowed_ref_[34].py (not in tracker).
5341
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005342- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005343 suppressed while an extension is loaded by calling SetErrorMode in
5344 dynload_win.c. The error is still reported properly.
5345
Georg Brandl3ee81df2008-05-17 18:14:43 +00005346- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005347 several extension methods and modules do not work without unicode
5348 support.
5349
Georg Brandl26543b12008-01-21 18:36:51 +00005350- Issue #1882: when compiling code from a string, encoding cookies in the
5351 second line of code were not always recognized correctly.
5352
Georg Brandl14404b62008-01-19 19:27:05 +00005353- Issue #1679: "0x" was taken as a valid integer literal.
5354
Georg Brandl6caad7d2008-01-26 14:19:22 +00005355- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005356 added.
5357
Christian Heimesc94e2b52008-01-14 04:13:37 +00005358- sys.float_info / PyFloat_GetInfo: The floating point information
5359 object was converted from a dict to a specialized structseq object.
5360
Georg Brandl3ee81df2008-05-17 18:14:43 +00005361- Patch #1816: Added sys.flags structseq. It exposes the status of
5362 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005363
Georg Brandl3ee81df2008-05-17 18:14:43 +00005364- Objects/structseq.c: Implemented new structseq representation. The
5365 patch makes structseqs (e.g. the return value of os.stat) more
5366 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005367
Georg Brandl3ee81df2008-05-17 18:14:43 +00005368- Patch #1700288: added a type attribute cache that caches method
5369 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005370
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005371- Bug #1776: __import__() no longer accepts filenames on any platform.
5372 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005373
Georg Brandlaed6c662008-01-07 17:25:53 +00005374- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5375
Georg Brandl3ee81df2008-05-17 18:14:43 +00005376- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5377 envvar and sys.dont_write_bytecode attribute. All these can be set
5378 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005379
Georg Brandl3ee81df2008-05-17 18:14:43 +00005380- Improve some exception messages when Windows fails to load an
5381 extension module. Now we get for example '%1 is not a valid Win32
5382 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005383

Christian Heimes0a8143f2007-12-18 23:22:54 +00005389- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005390 and INF. float("nan"), float("inf") and float("-inf") now work on
5391 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005392
Georg Brandl3ee81df2008-05-17 18:14:43 +00005393- Compiler now generates simpler and faster code for dictionary
5394 literals. The oparg for BUILD_MAP now indicates an estimated
5395 dictionary size. There is a new opcode, STORE_MAP, for adding
5396 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005425- Patch #1739468: Directories and zipfiles containing a __main__.py
5426 file can now be directly executed by passing their name to the
5427 interpreter. The directory/zipfile is automatically inserted as the
5428 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005429
Georg Brandl3ee81df2008-05-17 18:14:43 +00005430- Issue #1265: Fix a problem with sys.settrace, if the tracing
5431 function uses a generator expression when at the same time the
5432 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005433
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005434- sets and frozensets now have an isdisjoint() method.
5435
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005436- optimize the performance of builtin.sum().
5437
Neal Norwitz44f326e2007-10-05 05:29:17 +00005438- Fix warnings found by the new version of the Coverity checker.
5439
Georg Brandl21e99f42010-03-07 15:23:59 +00005440- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005441 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5442 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005443
Georg Brandl3ee81df2008-05-17 18:14:43 +00005444- Issue #1686386: Tuple's tp_repr did not take into account the
5445 possibility of having a self-referential tuple, which is possible
5446 from C code. Nor did object's tp_str consider that a type's tp_str
5447 could do something that could lead to an inifinite recursion.
5448 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5449 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005450
Georg Brandl3ee81df2008-05-17 18:14:43 +00005451- Issue #1164: It was possible to trigger deadlock when using the
5452 'print' statement to write to a file since the GIL was not released
5453 as needed. Now PyObject_Print() does the right thing along with
5454 various tp_print implementations of the built-in types and those in
5455 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005456
Georg Brandl3ee81df2008-05-17 18:14:43 +00005457- Issue #1147: Exceptions were directly allowing string exceptions in
5458 their throw() method even though string exceptions no longer
5459 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005460
Georg Brandl3ee81df2008-05-17 18:14:43 +00005461- Issue #1096: Prevent a segfault from getting the repr of a very
5462 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005463
Brett Cannon1e534b52007-09-07 04:18:30 +00005464- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005465 PyObject_Call() never calling back out to Python code to trigger
5466 recursion depth updates/checks. Required the creation of a static
5467 RuntimeError instance in case normalizing an exception put the
5468 recursion check value past its limit. Fixes crashers
5469 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005470
Georg Brandl3ee81df2008-05-17 18:14:43 +00005471- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005484- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005485 __*__ attributes. (Some already existed, e.g., __doc__ and
5486 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005487
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005488- Add -3 option to the interpreter to warn about features that are
5489 deprecated and will be changed/removed in Python 3.0.
5490
Georg Brandl2134e752007-05-21 20:34:16 +00005491- Patch #1686487: you can now pass any mapping after '**' in function
5492 calls.
5493
Collin Winter62903052007-05-18 23:11:24 +00005494- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005495 "except E as target:". This is to provide forwards compatibility
5496 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005497
Brett Cannon229cee22007-05-05 01:34:02 +00005498- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005500- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005501 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005502
Vinay Sajip8549ce32007-05-06 17:53:37 +00005503- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005504 setting a plain string, ie don't expand to single letter identifiers.
5505
Raymond Hettinger13936692007-04-11 18:40:58 +00005506- Request #1191699: Slices can now be pickled.
5507
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005508- Request #1193128: str.translate() now allows a None argument for
5509 translations that only remove characters without re-mapping the
5510 remaining characters.
5511
Georg Brandl5cb76c12007-03-21 09:00:39 +00005512- Patch #1682205: a TypeError while unpacking an iterable is no longer
5513 masked by a generic one with the message "unpack non-sequence".
5514
Neal Norwitzaa754b72007-03-21 06:39:48 +00005515- Remove unused file Python/fmod.c.
5516
Guido van Rossum143b5642007-03-23 04:58:42 +00005517- Bug #1683368: The object.__init__() and object.__new__() methods are
5518 now stricter in rejecting excess arguments. The only time when
5519 either allows excess arguments is when it is not overridden and the
5520 other one is. For backwards compatibility, when both are
5521 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005522 warning later). Also, type.__init__() insists on the same signature
5523 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005524
Georg Brandl3ee81df2008-05-17 18:14:43 +00005525- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5526 object to complex using its __complex__() method before falling back
5527 to the __float__() method. Therefore, the functions in the cmath
5528 module now can operate on objects that define a __complex__()
5529 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005530
Georg Brandl3ee81df2008-05-17 18:14:43 +00005531- Patch #1623563: allow __class__ assignment for classes with
5532 __slots__. The old and the new class are still required to have the
5533 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005534

Georg Brandl3ee81df2008-05-17 18:14:43 +00005538- Patch #1462488: Python no longer segfaults when
5539 ``object.__reduce_ex__()`` is called with an object that is faking
5540 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005541
Georg Brandl3ee81df2008-05-17 18:14:43 +00005542- Patch #1680015: Don't modify __slots__ tuple if it contains an

5546
Georg Brandl7b9c5552007-03-12 14:30:05 +00005547- Bug #1678647: write a newline after printing an exception in any
5548 case, even when converting the value to a string failed.
5549
Georg Brandl871f1bc2007-03-12 13:17:36 +00005550- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005551 its argument, if it exists. If not, it will work like before. This
5552 allows customizing the output of dir() in the presence of a
5553 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00005555- Patch #922167: Python no longer segfaults when faced with infinitely
5556 self-recursive reload() calls (as reported by bug #742342).
5557
Georg Brandl3ee81df2008-05-17 18:14:43 +00005558- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005561- Patch #1491866: change the complex() constructor to allow
5562 parthensized forms. This means complex(repr(x)) now works instead of
5563 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005564
Georg Brandlaa2321b2007-03-07 00:40:28 +00005565- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005566 makes the filenames the warning module prints much more sensible
5567 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005568
Georg Brandl49aafc92007-03-07 00:34:46 +00005569- Variant of patch #697613: don't exit the interpreter on a SystemExit
5570 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005571 variable is given, but break into the interactive interpreter just
5572 like on other exceptions or normal program exit.

6075
Facundo Batistad918a652007-04-24 13:54:38 +00006076- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006077 the client's request was successfully received, understood, and
6078 accepted. Now in these cases no error is raised in urllib (issue
6079 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006087- Added a timeout parameter to the constructor of other protocols
6088 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6089 work started with create_connection() and timeout in httplib, and
6090 closes patch #723312.
6091
Vinay Sajip8549ce32007-05-06 17:53:37 +00006092- Patch #1676823: Added create_connection() to socket.py, which may be

6116
Georg Brandlf66b6032007-03-14 08:27:52 +00006117- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006118 AttributeError instead of an IOError when the server's response
6119 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006120

Georg Brandl3ee81df2008-05-17 18:14:43 +00006125- Patch #1429539: pdb now correctly initializes the __main__ module
6126 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006127 correctly now.
6128

6135
Georg Brandl3ee81df2008-05-17 18:14:43 +00006136- Patch #1530482: add pydoc.render_doc() which returns the
6137 documentation for a thing instead of paging it to stdout, which

6151
Georg Brandl92a6bae2007-03-13 17:43:32 +00006152- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006153 are set for invalid interpolation sequences that would lead to
6154 errors on reading back those values.

Collin Winter22c42ba2007-03-10 02:51:26 +00006189

6197 returned string up to the first NUL character.

6208
Georg Brandl3ee81df2008-05-17 18:14:43 +00006209- unittest now verifies more of its assumptions. In particular,
6210 TestCase and TestSuite subclasses (not instances) are no longer
6211 accepted in TestSuite.addTest(). This should cause no
6212 incompatibility since it never made sense with ordinary subclasses
6213 -- the failure just occurred later, with a more cumbersome
6214 exception.

6223 given a unicode argument and os.listdir() returns unicode filenames.
6224
Georg Brandl3ee81df2008-05-17 18:14:43 +00006225- Patch #1673619: setup.py identifies extension modules it doesn't

6227 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006603 time so that opening a database previously created with the DB_DUP
6604 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6605 opens. Specifically: dictionary assignment to a DB object will
6606 replace all values for a given key when the database allows
6607 duplicate values. DB users should use DB.put(k, v) when they want
6608 to store duplicates; not DB[k] = v.

6615 characters with ASCII value less than 32. Also, it correctly quotes
6616 dots only if they occur on a single line, as opposed to the previous
6617 behavior of quoting dots if they are the second character of any
6618 line.
