531
Raymond Hettinger20397532010-09-12 02:11:45 +0000532- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
533 This prevents user-created self-referencing ordered dictionaries from
534 becoming permanently uncollectable GC garbage. The downside is that
535 removing __del__ means that the internal doubly-linked list has to wait for
536 GC collection rather than freeing memory immediately when the refcnt drops
537 to zero.
538
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000539- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

542
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000543- Issue #9792: In case of connection failure, socket.create_connection()
544 would swallow the exception and raise a new one, making it impossible
545 to fetch the original errno, or to filter timeout errors. Now the
546 original error is re-raised.
547
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000548- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
549 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
550 be updated back after the system call. Original patch by Brian Brazil.
551

556 ConfigParser.write.
557
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000558- Issue #808164: Fixed socket.close to avoid references to globals, to

569 character years even if the message contains RFC822 two character years.
570
Daniel Stutzbach91287322010-08-24 21:09:30 +0000571- Issue #8750: Fixed MutableSet's methods to correctly handle

590
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000591- Issue #9626: the view methods for collections.OrderedDict() were returning
592 the unordered versions inherited from dict. Those methods are now
593 overridden to provide ordered views.
594

998 of the number of bytes specified by the start byte.
999 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

1398 with a non-empty format string. This is an effort to future-proof user
1399 code. If a derived class does not currently implement __format__ but later
1400 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001401 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001402 Python 3.3 and it will be an error in Python 3.4.

1454 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1455 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001457- Issue #2531: Comparison operations between floats and Decimal instances now
1458 return a result based on the numeric values of the operands; previously they
1459 returned an arbitrary result based on the relative ordering of id(float) and
1460 id(Decimal).

1475 Fractions instance now raise TypeError instead of returning True/False. This
1476 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1477 <=> complex, and complex <=> complex comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00001584 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1585 inconsistent: __int__ was used for some integer codes but not for others, and
1586 the set of integer codes for which it was used differed between native packing
1587 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001895 file position when calling `truncate()`. It would previously change the file
1896 position to the given argument, which goes against the tradition of

1900 class used to represent files stored inside an archive. The new
1901 implementation is significantly faster and can be wrapped in a
1902 ``io.BufferedReader`` object for more speedups. It also solves an issue
1903 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002170- Issue #3382: 'F' formatting for float and complex now convert the result to
2171 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2172 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002173
Georg Brandlba83f822010-03-14 09:50:54 +00002174- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2175 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002176
Georg Brandlba83f822010-03-14 09:50:54 +00002177- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2178 1e-100 used to raise OverflowError, but now gives the requested 120
2179 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002187
Georg Brandlba83f822010-03-14 09:50:54 +00002188- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2189 decimal string that's guaranteed to round back to x under correct rounding
2190 (with round-half-to-even rounding mode). Previously it gave a string based on
2191 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2192 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2193 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002194
Georg Brandlba83f822010-03-14 09:50:54 +00002195- Issue #7117: On almost all platforms: float-to-string and string-to-float
2196 conversions within Python are now correctly rounded. Places these conversions
2197 occur include: str for floats and complex numbers; the float and complex
2198 constructors; old-style and new-style numeric formatting; serialization and
2199 deserialization of floats and complex numbers using marshal, pickle and json;
2200 parsing of float and imaginary literals in Python code; Decimal-to-float
2201 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002202
Georg Brandlba83f822010-03-14 09:50:54 +00002203 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2204 providing correctly-rounded strtod and dtoa C functions. This code is
2205 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2206 the C compiler. There may be a small number of platforms on which correct
2207 operation of this code cannot be guaranteed, so the code is not used: notably,
2208 this applies to platforms where the C double format is not IEEE 754 binary64,
2209 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2210 and Python's configure script is unable to determine how to change the FPU
2211 precision. On these platforms conversions use the platform strtod and dtoa,
2212 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002213
Georg Brandlba83f822010-03-14 09:50:54 +00002214- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2215 uses the correctly-rounded string <-> float conversions described above (when
2216 available), and so produces correctly rounded results that will display nicely
2217 under the float repr. There are two related small changes: (1) round now
2218 accepts any class with an ``__index__()`` method for its second argument (but
2219 no longer accepts floats for the second argument), and (2) an excessively
2220 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2221 raises an exception.

2224
Georg Brandlba83f822010-03-14 09:50:54 +00002225- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002363
Georg Brandlba83f822010-03-14 09:50:54 +00002364 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2365 (2) parsing of strings representing infinities and nans was locale aware; and
2366 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002368- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2369 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2370 but with at least one decimal point and with a default precision
2371 of 12. Previously, the behavior the same but with a default precision of 6.
2372 This more closely matches ``str()``, and reduces surprises when adding
2373 alignment flags to the empty presentation type. This also affects the new
2374 complex.__format__ in the same way.
2375
2376- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2377 classtype's, even if it was None. property now inserts the __doc__ into the
2378 subclass instance __dict__.

2448 internal representation of integers, for performance reasons. Base 2**30 is
2449 enabled by default on 64-bit machines. Add --enable-big-digits option to

3861 threads could return successfully while some Thread objects were still

3984 exactly the recursion limit is exceeded. Consequently, both exception types
3985 are caught and silenced.

4001
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004002- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4003
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004004- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4005 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4006 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4007 ``printf`` function, whereas PyString_FromFormat has an independent
4008 implementation and uses "%zd" on all platforms for size_t values.
4009 This makes a difference on win64, where ``printf`` needs "%Id" to display
4010 64bit values.
4011
Benjamin Peterson97179b02008-09-09 20:55:01 +00004012- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4013 error.
4014
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004015- Issue #3777: long() applied to a float object now always return a long
4016 object; previously an int would be returned for small values. the __long__
4017 method is allowed to return either an int or a long, but the behaviour of
4018 float objects should not change to respect backward compatibility.
4019
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004020- Issue #3751: str.rpartition would perform a left-partition when called with
4021 a unicode argument.
4022
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004023- Issue #3683: Fix compilation when --without-threads is given.
4024
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004025- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004026 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004027 was correctly parsed but parsing of subsequent arguments failed.
4028
Vinay Sajip35e3b032008-09-01 14:33:59 +00004029- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004030 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4031 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4032 when given a tuple of classes as second argument, were looking up
4033 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4034 type object.
4035
Neal Norwitz18aa3882008-08-24 05:04:52 +00004036- Fix crashes on memory allocation failure found with failmalloc.
4037
4038- Fix memory leaks found with valgrind and update suppressions file.
4039
4040- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4041
4042- Fix problem using wrong name in decimal module reported by pychecker.
4043
Christian Heimes7d4c3172008-08-22 19:47:25 +00004044- Silenced another compiler warning about a used but not defined
4045 function 'stringlib_contains_obj'.
4046
Benjamin Peterson712ee922008-08-24 18:10:20 +00004047- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
4048 ``__delslice__``.
4049
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004050- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4051 library targets in the Makefile.
4052
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004053- Issue #1204: The configure script now tests for additional libraries
4054 that may be required when linking against readline. This fixes issues
4055 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00004079 return a list or None rather than a custom object.

Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004081- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004105 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4106 for catch_warnings() also led to an improvement in the raising of a
4107 DeprecationWarning related to warnings.warn_explicit().
4108
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004109- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004177
4178Core and Builtins
4179-----------------
4180
Guido van Rossumf8402962008-08-20 15:01:50 +00004181- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4182 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4183 extensions do not automatically benefit from the class attribute
4184 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4185 to their tp_flags field if they care. This is a backwards
4186 compatibility feature; in 3.0, all types will use the cache by
4187 default.
4188
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004189- Keyword arguments can now follow starred arguments. (``f(a, *args,
4190 keyword=23)`` is now valid syntax.)
4191
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004192- ctypes function pointers that are COM methods have a boolean True
4193 value again.
4194
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004195- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4196 by denying s# to parse objects that have a releasebuffer procedure,
4197 and introducing s*.
4198
Georg Brandl1e13ea92008-08-11 09:07:59 +00004199- Issue #3537: Fix an assertion failure when an empty but presized dict
4200 object was stored in the freelist.
4201
Mark Dickinsonb6467572008-08-04 21:30:09 +00004202- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4203 ValueError consistently across platforms.
4204
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004205- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4206 (64bit Unix, for example), unichr() would truncate its argument and return
4207 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4208
Neal Norwitze7d8be82008-07-31 17:17:14 +00004209- Apply security patches from Apple.
4210
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004211- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4212 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4213
Antoine Pitrou92f82162008-07-25 22:22:08 +00004214- Issue #1819: function calls with several named parameters are now on
4215 average 35% faster (as measured by pybench).
4216
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004217- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4218 the python debugger steps into a class statement: the free variables (local
4219 variables defined in an outer scope) would be deleted from the outer scope.
4220
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004221- Issue #2620: Overflow checking when allocating or reallocating memory
4222 was not always being done properly in some python types and extension
4223 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4224 all been updated to perform better checks and places in the code that
4225 would previously leak memory on the error path when such an allocation
4226 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00004233- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4234 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4235
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004236- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4237 version reported by these tools does not necessarily follow the python
4238 version numbering scheme, so the module is less strict when parsing it.
4239
Nick Coghlanf70385a2008-08-18 12:42:46 +00004240- Issue #2235: Added Py3k warnings for types which will become unhashable
4241 under the stricter __hash__ inheritance rules in 3.0. Several types
4242 which did not meet the rules for hash invariants and were already
4243 unhashable in 3.0 have now been explicitly flagged as unhashable in
4244 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4245 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4246
Brett Cannon88f801d2008-08-18 00:46:22 +00004247- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4248 imported into the module but exposed as part of the module's API.
4249
Brett Cannon7b96f072008-08-18 00:41:11 +00004250- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004254- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4255
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004256- Issue #3575: Incremental decoder's decode function now takes bytearray
4257 by using 's*' instead of 't#'.
4258
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004259- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004260 fails unicode conversion on 2nd parameter. (windows only)

Antoine Pitroude781a42008-08-09 12:43:23 +00004316 asking for a specific length. This problem only affected files opened

4360
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004361- Issue #643841: The language reference now provides more detailed

4373-----------------
4374
Georg Brandl3e483f62008-07-16 22:57:41 +00004375- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4376 its methods now allow for items objects that can be converted to
4377 an integer using operator.index().
4378
Mark Dickinson64b7e502008-07-16 09:40:03 +00004379- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4380 produced a ValueError instead of giving the correct float.
4381
Eric Smitha5fa5a22008-07-16 00:11:49 +00004382- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4383 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4384
Mark Dickinson7103aa42008-07-15 19:08:33 +00004385- Issue #3008: the float type has a new instance method 'float.hex'
4386 and a new class method 'float.fromhex' to convert floating-point
4387 numbers to and from hexadecimal strings, respectively.
4388
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004389- Issue #2235: __hash__ is once again inherited by default. To allow
4390 collections.Hashable to remain meaningful in the presence of the
4391 default hash implementation (object.__hash__), it is now possible
4392 to explicit block inheritance of hash by setting __hash__=None at
4393 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4394 level.
4395
Nick Coghlanb028f502008-07-13 14:52:36 +00004396- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4397 the parent module cannot be found while performing an absolute import.
4398 This means that an incorrectly defined __package__ attribute will
4399 now only prevent relative imports in that module rather than causing
4400 all imports from that module to fail.
4401
Nick Coghlan14ff9942008-07-08 14:21:42 +00004402- Issue #2517: Allow unicode messages in Exceptions again by correctly
4403 bypassing the instance dictionary when looking up __unicode__ on
4404 new-style classes.

4412 another thread's dictionary.
4413
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004414- Issue #3004: Minor change to slice.indices(): the start and stop
4415 arguments are now treated identically, making the behaviour easier
4416 to describe and understand. For example, slice(None, -10,
4417 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4418 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4419 10, -1).
4420
Georg Brandl278fc502008-07-19 12:46:12 +00004421- Issue #3219: Calling a function with repeated keyword arguments,
4422 f(a=2, a=23), would not cause a syntax error. This was a regression
4423 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00004425- Issue #2862: Make int and float freelist management consistent with
4426 other freelists. Changes their CompactFreeList apis into

4433 api functions without holding the GIL, which could lead to a fatal
4434 error when they failed.
4435
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004436- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004461- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4462 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004463 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004464 content-length. The problem had been corrected in the 2.4 branch, but never
4465 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004480- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4482
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004483- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

4870
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004871- On MacOS X it is now possible to install the framework in 64-bit
4872 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004873 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004874
4875 This is controlled by the configure argument ``--with-universal-archs``:
4876
4877 - ``--with-universal-archs=all``: install 4-way universal
4878
4879 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4880
4881 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4882
4883 This option should be used in combination with ``--enable-universalsdk=``.
4884
4885 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004935- Issue #1631171: Re-implement the 'warnings' module in C (the
4936 original Python code has been kept as backup). This will allow for
4937 using the 'warning's machinery in such places as the parser where
4938 use of pure Python code is not possible. Both the ``showarning()``
4939 and ``formatwarning()`` gain an optional 'line' argument which is
4940 not called by default for backwards-compatibility reasons. Setting
4941 ``warnings.showwarning()`` to an implementation that lacks support
4942 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005005- Issue #2550: The approach used by client/server code for obtaining
5006 ports to listen on in network-oriented tests has been refined in an
5007 effort to facilitate running multiple instances of the entire
5008 regression test suite in parallel without issue.
5009 test_support.bind_port() has been fixed such that it will always
5010 return a unique port -- which wasn't always the case with the
5011 previous implementation, especially if socket options had been set
5012 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5013 new implementation of bind_port() will actually raise an exception
5014 if it is passed an AF_INET/SOCK_STREAM socket with either the
5015 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5016 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5017 the socket it's been passed. This currently only applies to
5018 Windows. This option prevents any other sockets from binding to the
5019 host/port we've bound to, thus removing the possibility of the
5020 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5021 when a second SOCK_STREAM socket binds and accepts to a host/port
5022 that's already been bound by another socket. The optional preferred
5023 port parameter to bind_port() has been removed. Under no
5024 circumstances should tests be hard coding ports!
5025
5026 test_support.find_unused_port() has also been introduced, which will
5027 pass a temporary socket object to bind_port() in order to obtain an
5028 unused port. The temporary socket object is then closed and
5029 deleted, and the port is returned. This method should only be used
5030 for obtaining an unused port in order to pass to an external program
5031 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5032 a parameter to a server-oriented class that doesn't give you direct
5033 access to the underlying socket used.
5034
5035 Finally, test_support.HOST has been introduced, which should be used
5036 for the host argument of any relevant socket calls (i.e. bind and
5037 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005038
5039 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005040 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005041 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5042 test_asynchat and test_socket_ssl.
5043
Georg Brandl3ee81df2008-05-17 18:14:43 +00005044 It is now possible for multiple instances of the regression test
5045 suite to run in parallel without issue.

5103 this case, like normal unicode literals and the 'unicode-escape'
5104 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00005324- Added the future_builtins module, which contains hex() and oct().
5325 These are the PEP 3127 version of these functions, designed to be
5326 compatible with the hex() and oct() builtins from Python 3.0. They
5327 differ slightly in their output formats from the existing, unchanged
5328 Python 2.6 builtins. The expected usage of the future_builtins
5329 module is:
5330 from future_builtins import hex, oct
5331
Eric Smith7ef40bf2008-02-20 23:34:22 +00005332- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5333 exponents for exponents with absolute value < 100. Follows C99
5334 standard. This is a change on Windows, which would use 3 digits.
5335 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5336 so that any alterations it does to the resulting string will be
5337 available in stringlib/formatter.h (for float.__format__).
5338
Eric Smith5a3c1352008-02-19 13:21:56 +00005339- Implemented PEP 3101, Advanced String Formatting. This adds a new
5340 builtin format(); a format() method for str and unicode; a
5341 __format__() method to object, str, unicode, int, long, float, and
5342 datetime; the class string.Formatter; and the C API
5343 PyObject_Format().
5344
Georg Brandl3ee81df2008-05-17 18:14:43 +00005345- Fixed several potential crashes, all caused by specially crafted
5346 __del__ methods exploiting objects in temporarily inconsistent
5347 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005356- Clear all free lists during a gc.collect() of the highest generation
5357 in order to allow pymalloc to free more arenas. Python may give back
5358 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005359
Georg Brandl3ee81df2008-05-17 18:14:43 +00005360- Issue #2045: Fix an infinite recursion triggered when printing a
5361 subclass of collections.defaultdict, if its default_factory is set
5362 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005363
Christian Heimesf75dbef2008-02-08 00:11:31 +00005364- Fixed a minor memory leak in dictobject.c. The content of the free
5365 list was not freed on interpreter shutdown.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005390- Patch #1473257: generator objects gain a gi_code attribute. This is
5391 the same object as the func_code attribute of the function that
5392 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005393
Georg Brandl3ee81df2008-05-17 18:14:43 +00005394- Issue #1920: "while 0" statements were completely removed by the
5395 compiler, even in the presence of an "else" clause, which is
5396 supposed to be run when the condition is false. Now the compiler
5397 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005398
Guido van Rossumeead05f2008-01-24 18:21:02 +00005399- A few crashers fixed: weakref_in_del.py (issue #1377858);

5401 borrowed_ref_[34].py (not in tracker).
5402
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005403- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005404 suppressed while an extension is loaded by calling SetErrorMode in
5405 dynload_win.c. The error is still reported properly.
5406
Georg Brandl3ee81df2008-05-17 18:14:43 +00005407- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005408 several extension methods and modules do not work without unicode
5409 support.
5410

5415
Georg Brandl6caad7d2008-01-26 14:19:22 +00005416- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005417 added.
5418
Christian Heimesc94e2b52008-01-14 04:13:37 +00005419- sys.float_info / PyFloat_GetInfo: The floating point information
5420 object was converted from a dict to a specialized structseq object.
5421
Georg Brandl3ee81df2008-05-17 18:14:43 +00005422- Patch #1816: Added sys.flags structseq. It exposes the status of
5423 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005424
Georg Brandl3ee81df2008-05-17 18:14:43 +00005425- Objects/structseq.c: Implemented new structseq representation. The
5426 patch makes structseqs (e.g. the return value of os.stat) more
5427 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005428
Georg Brandl3ee81df2008-05-17 18:14:43 +00005429- Patch #1700288: added a type attribute cache that caches method
5430 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005431
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005432- Bug #1776: __import__() no longer accepts filenames on any platform.
5433 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00005435- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5436
Georg Brandl3ee81df2008-05-17 18:14:43 +00005437- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5438 envvar and sys.dont_write_bytecode attribute. All these can be set
5439 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005440
Georg Brandl3ee81df2008-05-17 18:14:43 +00005441- Improve some exception messages when Windows fails to load an
5442 extension module. Now we get for example '%1 is not a valid Win32
5443 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005444

Christian Heimes0a8143f2007-12-18 23:22:54 +00005450- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005451 and INF. float("nan"), float("inf") and float("-inf") now work on
5452 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005453
Georg Brandl3ee81df2008-05-17 18:14:43 +00005454- Compiler now generates simpler and faster code for dictionary
5455 literals. The oparg for BUILD_MAP now indicates an estimated
5456 dictionary size. There is a new opcode, STORE_MAP, for adding
5457 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005486- Patch #1739468: Directories and zipfiles containing a __main__.py
5487 file can now be directly executed by passing their name to the
5488 interpreter. The directory/zipfile is automatically inserted as the
5489 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005491- Issue #1265: Fix a problem with sys.settrace, if the tracing
5492 function uses a generator expression when at the same time the
5493 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005494
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005495- sets and frozensets now have an isdisjoint() method.
5496
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005497- optimize the performance of builtin.sum().

5500
Georg Brandl21e99f42010-03-07 15:23:59 +00005501- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005502 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5503 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005504
Georg Brandl3ee81df2008-05-17 18:14:43 +00005505- Issue #1686386: Tuple's tp_repr did not take into account the
5506 possibility of having a self-referential tuple, which is possible
5507 from C code. Nor did object's tp_str consider that a type's tp_str
5508 could do something that could lead to an inifinite recursion.
5509 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5510 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005511
Georg Brandl3ee81df2008-05-17 18:14:43 +00005512- Issue #1164: It was possible to trigger deadlock when using the
5513 'print' statement to write to a file since the GIL was not released
5514 as needed. Now PyObject_Print() does the right thing along with
5515 various tp_print implementations of the built-in types and those in
5516 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005517
Georg Brandl3ee81df2008-05-17 18:14:43 +00005518- Issue #1147: Exceptions were directly allowing string exceptions in
5519 their throw() method even though string exceptions no longer
5520 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00005525- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005526 PyObject_Call() never calling back out to Python code to trigger
5527 recursion depth updates/checks. Required the creation of a static
5528 RuntimeError instance in case normalizing an exception put the
5529 recursion check value past its limit. Fixes crashers
5530 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005531

Neal Norwitz0ac60192007-05-27 04:08:54 +00005545- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005546 __*__ attributes. (Some already existed, e.g., __doc__ and
5547 __name__.)

5551
Georg Brandl2134e752007-05-21 20:34:16 +00005552- Patch #1686487: you can now pass any mapping after '**' in function
5553 calls.
5554
Collin Winter62903052007-05-18 23:11:24 +00005555- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005556 "except E as target:". This is to provide forwards compatibility
5557 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005564- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005565 setting a plain string, ie don't expand to single letter identifiers.
5566
Raymond Hettinger13936692007-04-11 18:40:58 +00005567- Request #1191699: Slices can now be pickled.
5568
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005569- Request #1193128: str.translate() now allows a None argument for

5571 remaining characters.
5572
Georg Brandl5cb76c12007-03-21 09:00:39 +00005573- Patch #1682205: a TypeError while unpacking an iterable is no longer

5577
Guido van Rossum143b5642007-03-23 04:58:42 +00005578- Bug #1683368: The object.__init__() and object.__new__() methods are
5579 now stricter in rejecting excess arguments. The only time when
5580 either allows excess arguments is when it is not overridden and the
5581 other one is. For backwards compatibility, when both are
5582 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005583 warning later). Also, type.__init__() insists on the same signature
5584 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005586- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5587 object to complex using its __complex__() method before falling back
5588 to the __float__() method. Therefore, the functions in the cmath
5589 module now can operate on objects that define a __complex__()
5590 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005612 its argument, if it exists. If not, it will work like before. This
5613 allows customizing the output of dir() in the presence of a
5614 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00005626- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00005696- Bug #1545497: when given an explicit base, int() did ignore NULs
5697 embedded in the string to convert.
5698
Georg Brandl846f73a2006-10-08 07:11:54 +00005699- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00005747 generator expressions (x for x, in ... ) works again. Fixing this
5748 problem required changing the .pyc magic number. This means that
5749 .pyc files generated before 2.5c2 will be regenerated.

6557 with RFC 3207 and forgets any knowledge obtained from the server not
6558 obtained from the TLS negotiation itself. Patch contributed by Bill
6559 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006561- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006562 that the SMTP.starttls() caller no longer needs to call ehlo()
6563 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006564 does not claim to support starttls. Adds the
6565 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6566 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006645- Marshal.dumps() now expects exact type matches for int, long, float,
6646 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6647 silently miscode subclasses of those types. Now, it raises a
6648 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006649

Georg Brandl3ee81df2008-05-17 18:14:43 +00006664 time so that opening a database previously created with the DB_DUP
6665 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6666 opens. Specifically: dictionary assignment to a DB object will
6667 replace all values for a given key when the database allows
6668 duplicate values. DB users should use DB.put(k, v) when they want
6669 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006670

6676 characters with ASCII value less than 32. Also, it correctly quotes
6677 dots only if they occur on a single line, as opposed to the previous
6678 behavior of quoting dots if they are the second character of any
6679 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006680
