128
Ned Deily87e82bb2011-06-28 19:52:59 -0700129- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
130 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
131 interpreter process. This could cause failures in non-Distutils subprocesses
132 and was unreliable since tests or user programs could modify the interpreter
133 environment after Distutils set it. Instead, have Distutils set the the
134 deployment target only in the environment of each build subprocess. It is
135 still possible to globally override the default by setting
136 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
137 greater or equal to the default value, the value with which the interpreter
138 was built.

144 Kitada.
145
R David Murrayf1138bb2011-06-17 22:23:04 -0400146- Issue #11700: mailbox proxy object close methods can now be called multiple
147 times without error, and _ProxyFile now closes the wrapped file.
148
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200149- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
150 connection if its getresponse() method fails with a socket error. Patch
151 written by Ezio Melotti.
152
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500153- Issue #9284: Allow inspect.findsource() to find the source of doctest
154 functions.
155

165
Barry Warsawc5643282011-07-19 17:06:30 -0400166- sys.setcheckinterval() now updates the current ticker count as well as
167 updating the check interval, so if the user decreases the check interval,
168 the ticker doesn't have to wind down to zero from the old starting point
169 before the new interval takes effect. And if the user increases the
170 interval, it makes sure the new limit takes effect right away rather have an
171 early task switch before recognizing the new interval.

1029 This prevents user-created self-referencing ordered dictionaries from
1030 becoming permanently uncollectable GC garbage. The downside is that
1031 removing __del__ means that the internal doubly-linked list has to wait for
1032 GC collection rather than freeing memory immediately when the refcnt drops
1033 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001492- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1493 start byte and the continuation byte(s) are now considered invalid, instead
1494 of the number of bytes specified by the start byte.
1495 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1496 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1497 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1498 Previous versions returned a single u'\ufffd'.

1502 arises from the "Overriding __eq__ blocks inheritance ..." warning
1503 when turned into an exception: in this case the exception simply
1504 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001506- Issue #8748: Fix two issues with comparisons between complex and integer
1507 objects. (1) The comparison could incorrectly return True in some cases
1508 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1509 (2) The comparison raised an OverflowError for large integers, leading
1510 to unpredictable exceptions when combining integers and complex objects
1511 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001513- Issue #5211: Implicit coercion for the complex type is now completely

1881 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00001893- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1894 with a non-empty format string. This is an effort to future-proof user
1895 code. If a derived class does not currently implement __format__ but later
1896 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001897 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001898 Python 3.3 and it will be an error in Python 3.4.

1949 InvalidOperation instead of returning False. (Comparisons involving a quiet
1950 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1951 signaling NaNs remain unhashable.

1971 Fractions instance now raise TypeError instead of returning True/False. This
1972 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1973 <=> complex, and complex <=> complex comparisons.

2348 strings,
2349 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2350 numeric strings corresponding to subnormal values,
2351 (3) a memory leak for some values large enough to cause overflow, and
2352 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002383- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002384 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002390- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002391 file position when calling `truncate()`. It would previously change the file
2392 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002393 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2394

2396 class used to represent files stored inside an archive. The new
2397 implementation is significantly faster and can be wrapped in a
2398 ``io.BufferedReader`` object for more speedups. It also solves an issue
2399 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002410- Issue #7748: Since unicode values are supported for some metadata options in
2411 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2412 encoded string for them. This ensures that the upload and register commands
2413 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002490- The ``__complex__()`` method is now looked up on the class of instances to
2491 make it consistent with other special methods.

2495
Mark Dickinson1b34d252010-01-01 17:27:30 +00002496- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002497 DeprecationWarning when passed a float argument where an integer was expected.
2498 These functions and methods now raise TypeError instead. The majority of the
2499 effects of this change are in the extension modules, but some core functions
2500 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2501 and many unicode/str methods.

2515 of integers: the result of a/b is now correctly rounded for ints a and b (at
2516 least on IEEE 754 platforms), and in particular does not depend on the
2517 internal representation of a long.

2525
Georg Brandlba83f822010-03-14 09:50:54 +00002526 These executables now work properly with the arch(1) command: ``arch -ppc

2687 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2688 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2689 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002691- Issue #7117: On almost all platforms: float-to-string and string-to-float
2692 conversions within Python are now correctly rounded. Places these conversions
2693 occur include: str for floats and complex numbers; the float and complex
2694 constructors; old-style and new-style numeric formatting; serialization and
2695 deserialization of floats and complex numbers using marshal, pickle and json;
2696 parsing of float and imaginary literals in Python code; Decimal-to-float
2697 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002698
Georg Brandlba83f822010-03-14 09:50:54 +00002699 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2700 providing correctly-rounded strtod and dtoa C functions. This code is
2701 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2702 the C compiler. There may be a small number of platforms on which correct
2703 operation of this code cannot be guaranteed, so the code is not used: notably,
2704 this applies to platforms where the C double format is not IEEE 754 binary64,
2705 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2706 and Python's configure script is unable to determine how to change the FPU
2707 precision. On these platforms conversions use the platform strtod and dtoa,
2708 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002710- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2711 uses the correctly-rounded string <-> float conversions described above (when
2712 available), and so produces correctly rounded results that will display nicely
2713 under the float repr. There are two related small changes: (1) round now
2714 accepts any class with an ``__index__()`` method for its second argument (but
2715 no longer accepts floats for the second argument), and (2) an excessively
2716 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2717 raises an exception.

3123 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00004297 - If x is not an int, long or float, then packing x will always result in
4298 struct.error. Previously an x with an __int__ method could be packed by
4299 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4300 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4301 neither __int__ nor __long__, TypeError used to be raised (with a
4302 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4303 struct.error in other cases.

4306 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004500- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4501 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4502 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4503 ``printf`` function, whereas PyString_FromFormat has an independent
4504 implementation and uses "%zd" on all platforms for size_t values.
4505 This makes a difference on win64, where ``printf`` needs "%Id" to display
4506 64bit values.

4512 object; previously an int would be returned for small values. the __long__
4513 method is allowed to return either an int or a long, but the behaviour of

Brett Cannon1eaf0742008-09-02 01:25:16 +00004601 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4602 for catch_warnings() also led to an improvement in the raising of a
4603 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004669What's New in Python 2.6 beta 3?
4670================================
4671
Barry Warsaw07a4a382008-08-21 01:15:08 +00004672*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004673
4674Core and Builtins
4675-----------------
4676
Guido van Rossumf8402962008-08-20 15:01:50 +00004677- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4678 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4679 extensions do not automatically benefit from the class attribute
4680 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4681 to their tp_flags field if they care. This is a backwards
4682 compatibility feature; in 3.0, all types will use the cache by
4683 default.
4684
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004685- Keyword arguments can now follow starred arguments. (``f(a, *args,
4686 keyword=23)`` is now valid syntax.)
4687
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004688- ctypes function pointers that are COM methods have a boolean True
4689 value again.
4690
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004691- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4692 by denying s# to parse objects that have a releasebuffer procedure,
4693 and introducing s*.
4694
Georg Brandl1e13ea92008-08-11 09:07:59 +00004695- Issue #3537: Fix an assertion failure when an empty but presized dict
4696 object was stored in the freelist.
4697
Mark Dickinsonb6467572008-08-04 21:30:09 +00004698- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4699 ValueError consistently across platforms.
4700
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004701- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4702 (64bit Unix, for example), unichr() would truncate its argument and return
4703 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4704
Neal Norwitze7d8be82008-07-31 17:17:14 +00004705- Apply security patches from Apple.
4706
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004707- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4708 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4709
Antoine Pitrou92f82162008-07-25 22:22:08 +00004710- Issue #1819: function calls with several named parameters are now on
4711 average 35% faster (as measured by pybench).
4712
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004713- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4714 the python debugger steps into a class statement: the free variables (local
4715 variables defined in an outer scope) would be deleted from the outer scope.
4716
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004717- Issue #2620: Overflow checking when allocating or reallocating memory
4718 was not always being done properly in some python types and extension
4719 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4720 all been updated to perform better checks and places in the code that
4721 would previously leak memory on the error path when such an allocation
4722 failed have been fixed.

4725-------
4726
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004727- Issue #3612: Added some missing basic types in ctypes.wintypes.
4728
Benjamin Petersone977ad42008-08-20 01:42:01 +00004729- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4730 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4731
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004732- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4733 version reported by these tools does not necessarily follow the python
4734 version numbering scheme, so the module is less strict when parsing it.
4735
Nick Coghlanf70385a2008-08-18 12:42:46 +00004736- Issue #2235: Added Py3k warnings for types which will become unhashable
4737 under the stricter __hash__ inheritance rules in 3.0. Several types
4738 which did not meet the rules for hash invariants and were already
4739 unhashable in 3.0 have now been explicitly flagged as unhashable in
4740 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4741 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4742
Brett Cannon88f801d2008-08-18 00:46:22 +00004743- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4744 imported into the module but exposed as part of the module's API.
4745
Brett Cannon7b96f072008-08-18 00:41:11 +00004746- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4747
Brett Cannon46225e72008-08-18 00:36:52 +00004748- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004750- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4751
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004752- Issue #3575: Incremental decoder's decode function now takes bytearray
4753 by using 's*' instead of 't#'.
4754
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004755- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004756 fails unicode conversion on 2nd parameter. (windows only)
4757
Georg Brandl222e2082010-08-01 22:27:39 +00004758- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004759 in a redirect.
4760
Brett Cannonabe423e2008-08-16 21:47:07 +00004761- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004762 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004763
Facundo Batistaeb90b782008-08-16 14:44:07 +00004764- Issue #2776: fixed small issue when handling an URL with double slash
4765 after a 302 response in the case of not going through a proxy.
4766
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004767- Issue #2676: in the email package, content-type parsing was hanging on
4768 pathological input because of quadratic or exponential behaviour of a
4769 regular expression.
4770
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004771- Issue #3476: binary buffered reading through the new "io" library is now
4772 thread-safe.
4773
Brett Cannonbf3157b2008-08-14 05:00:03 +00004774- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4775 since mimetools itself is deprecated. Because modules are cached, all
4776 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4777
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004778- Issue #3134: shutil referenced undefined WindowsError symbol.
4779
Robert Schuppenies14646332008-08-10 11:01:53 +00004780- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4781 menu entries were not deleted.
4782
Brett Cannon83e81842008-08-09 23:30:55 +00004783- Copied the implementation of reduce() to _functools.reduce() to have a
4784 version that did not raise a DeprecationWarning under -3.
4785
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004786- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4787 a MemoryError rather than silently stop the iteration.
4788
Guido van Rossum59ce9012008-08-09 14:55:34 +00004789- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4790 to _sre.compile() will now be rejected. This should not affect anybody
4791 since the re.compile() function never generates invalid re-bytecode.
4792
Skip Montanaroa032bf42008-08-08 22:52:51 +00004793- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4794 upon first access it can be automatically initialized from the csv file if
4795 it wasn't initialized during instantiation.
4796
Brett Cannon3aa2a492008-08-06 22:28:09 +00004797- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4798 the reload() built-in has been removed.
4799
Brett Cannon7e30b672008-08-04 21:52:25 +00004800- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004801 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004812 asking for a specific length. This problem only affected files opened
4813 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004814
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004815- Issue #3449: Update decimal module to use most recent specification
4816 (v. 1.68) and tests (v. 2.58) from IBM.

4856
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004857- Issue #643841: The language reference now provides more detailed

4869-----------------
4870
Georg Brandl3e483f62008-07-16 22:57:41 +00004871- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4872 its methods now allow for items objects that can be converted to
4873 an integer using operator.index().
4874
Mark Dickinson64b7e502008-07-16 09:40:03 +00004875- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4876 produced a ValueError instead of giving the correct float.
4877
Eric Smitha5fa5a22008-07-16 00:11:49 +00004878- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4879 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4880
Mark Dickinson7103aa42008-07-15 19:08:33 +00004881- Issue #3008: the float type has a new instance method 'float.hex'
4882 and a new class method 'float.fromhex' to convert floating-point
4883 numbers to and from hexadecimal strings, respectively.
4884
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004885- Issue #2235: __hash__ is once again inherited by default. To allow
4886 collections.Hashable to remain meaningful in the presence of the
4887 default hash implementation (object.__hash__), it is now possible
4888 to explicit block inheritance of hash by setting __hash__=None at
4889 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4890 level.
4891
Nick Coghlanb028f502008-07-13 14:52:36 +00004892- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4893 the parent module cannot be found while performing an absolute import.
4894 This means that an incorrectly defined __package__ attribute will
4895 now only prevent relative imports in that module rather than causing
4896 all imports from that module to fail.
4897
Nick Coghlan14ff9942008-07-08 14:21:42 +00004898- Issue #2517: Allow unicode messages in Exceptions again by correctly

4903 set to a custom object whose write() method happens to install
4904 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004906- Issue #3088: Corrected a race condition in classes derived from
4907 threading.local: the first member set by a thread could be saved in
4908 another thread's dictionary.
4909
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004910- Issue #3004: Minor change to slice.indices(): the start and stop
4911 arguments are now treated identically, making the behaviour easier
4912 to describe and understand. For example, slice(None, -10,
4913 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4914 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4915 10, -1).
4916
Georg Brandl278fc502008-07-19 12:46:12 +00004917- Issue #3219: Calling a function with repeated keyword arguments,
4918 f(a=2, a=23), would not cause a syntax error. This was a regression
4919 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004920
Georg Brandl278fc502008-07-19 12:46:12 +00004921- Issue #2862: Make int and float freelist management consistent with
4922 other freelists. Changes their CompactFreeList apis into
4923 ClearFreeList apis and calls them via gc.collect().

4929 api functions without holding the GIL, which could lead to a fatal
4930 error when they failed.
4931
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004932- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004957- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4958 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004959 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004960 content-length. The problem had been corrected in the 2.4 branch, but never
4961 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004976- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4977 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00005431- Issue #1631171: Re-implement the 'warnings' module in C (the
5432 original Python code has been kept as backup). This will allow for
5433 using the 'warning's machinery in such places as the parser where
5434 use of pure Python code is not possible. Both the ``showarning()``
5435 and ``formatwarning()`` gain an optional 'line' argument which is
5436 not called by default for backwards-compatibility reasons. Setting
5437 ``warnings.showwarning()`` to an implementation that lacks support
5438 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005501- Issue #2550: The approach used by client/server code for obtaining
5502 ports to listen on in network-oriented tests has been refined in an
5503 effort to facilitate running multiple instances of the entire
5504 regression test suite in parallel without issue.
5505 test_support.bind_port() has been fixed such that it will always
5506 return a unique port -- which wasn't always the case with the
5507 previous implementation, especially if socket options had been set
5508 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5509 new implementation of bind_port() will actually raise an exception
5510 if it is passed an AF_INET/SOCK_STREAM socket with either the
5511 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5512 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5513 the socket it's been passed. This currently only applies to
5514 Windows. This option prevents any other sockets from binding to the
5515 host/port we've bound to, thus removing the possibility of the
5516 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5517 when a second SOCK_STREAM socket binds and accepts to a host/port
5518 that's already been bound by another socket. The optional preferred
5519 port parameter to bind_port() has been removed. Under no
5520 circumstances should tests be hard coding ports!
5521
5522 test_support.find_unused_port() has also been introduced, which will
5523 pass a temporary socket object to bind_port() in order to obtain an
5524 unused port. The temporary socket object is then closed and
5525 deleted, and the port is returned. This method should only be used
5526 for obtaining an unused port in order to pass to an external program
5527 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5528 a parameter to a server-oriented class that doesn't give you direct
5529 access to the underlying socket used.
5530
5531 Finally, test_support.HOST has been introduced, which should be used
5532 for the host argument of any relevant socket calls (i.e. bind and
5533 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005534
5535 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005536 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005537 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5538 test_asynchat and test_socket_ssl.
5539
Georg Brandl3ee81df2008-05-17 18:14:43 +00005540 It is now possible for multiple instances of the regression test
5541 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005820- Added the future_builtins module, which contains hex() and oct().
5821 These are the PEP 3127 version of these functions, designed to be
5822 compatible with the hex() and oct() builtins from Python 3.0. They
5823 differ slightly in their output formats from the existing, unchanged
5824 Python 2.6 builtins. The expected usage of the future_builtins
5825 module is:
5826 from future_builtins import hex, oct
5827
Eric Smith7ef40bf2008-02-20 23:34:22 +00005828- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5829 exponents for exponents with absolute value < 100. Follows C99
5830 standard. This is a change on Windows, which would use 3 digits.
5831 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5832 so that any alterations it does to the resulting string will be
5833 available in stringlib/formatter.h (for float.__format__).
5834
Eric Smith5a3c1352008-02-19 13:21:56 +00005835- Implemented PEP 3101, Advanced String Formatting. This adds a new
5836 builtin format(); a format() method for str and unicode; a
5837 __format__() method to object, str, unicode, int, long, float, and
5838 datetime; the class string.Formatter; and the C API
5839 PyObject_Format().
5840
Georg Brandl3ee81df2008-05-17 18:14:43 +00005841- Fixed several potential crashes, all caused by specially crafted
5842 __del__ methods exploiting objects in temporarily inconsistent
5843 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005886- Patch #1473257: generator objects gain a gi_code attribute. This is
5887 the same object as the func_code attribute of the function that
5888 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005889
Georg Brandl3ee81df2008-05-17 18:14:43 +00005890- Issue #1920: "while 0" statements were completely removed by the
5891 compiler, even in the presence of an "else" clause, which is
5892 supposed to be run when the condition is false. Now the compiler
5893 correctly emits bytecode for the "else" suite.

5911
Georg Brandl6caad7d2008-01-26 14:19:22 +00005912- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005913 added.
5914
Christian Heimesc94e2b52008-01-14 04:13:37 +00005915- sys.float_info / PyFloat_GetInfo: The floating point information
5916 object was converted from a dict to a specialized structseq object.
5917
Georg Brandl3ee81df2008-05-17 18:14:43 +00005918- Patch #1816: Added sys.flags structseq. It exposes the status of
5919 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005920
Georg Brandl3ee81df2008-05-17 18:14:43 +00005921- Objects/structseq.c: Implemented new structseq representation. The
5922 patch makes structseqs (e.g. the return value of os.stat) more
5923 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005924
Georg Brandl3ee81df2008-05-17 18:14:43 +00005925- Patch #1700288: added a type attribute cache that caches method
5926 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005927
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005928- Bug #1776: __import__() no longer accepts filenames on any platform.
5929 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005930
Georg Brandlaed6c662008-01-07 17:25:53 +00005931- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5932
Georg Brandl3ee81df2008-05-17 18:14:43 +00005933- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5934 envvar and sys.dont_write_bytecode attribute. All these can be set
5935 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005936
Georg Brandl3ee81df2008-05-17 18:14:43 +00005937- Improve some exception messages when Windows fails to load an
5938 extension module. Now we get for example '%1 is not a valid Win32
5939 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005940

5944 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005945
Christian Heimes0a8143f2007-12-18 23:22:54 +00005946- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005947 and INF. float("nan"), float("inf") and float("-inf") now work on
5948 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005949
Georg Brandl3ee81df2008-05-17 18:14:43 +00005950- Compiler now generates simpler and faster code for dictionary
5951 literals. The oparg for BUILD_MAP now indicates an estimated
5952 dictionary size. There is a new opcode, STORE_MAP, for adding
5953 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005982- Patch #1739468: Directories and zipfiles containing a __main__.py
5983 file can now be directly executed by passing their name to the
5984 interpreter. The directory/zipfile is automatically inserted as the
5985 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005986
Georg Brandl3ee81df2008-05-17 18:14:43 +00005987- Issue #1265: Fix a problem with sys.settrace, if the tracing
5988 function uses a generator expression when at the same time the
5989 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005990
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005991- sets and frozensets now have an isdisjoint() method.
5992
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005993- optimize the performance of builtin.sum().
5994
Neal Norwitz44f326e2007-10-05 05:29:17 +00005995- Fix warnings found by the new version of the Coverity checker.
5996
Georg Brandl21e99f42010-03-07 15:23:59 +00005997- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005998 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5999 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006000
Georg Brandl3ee81df2008-05-17 18:14:43 +00006001- Issue #1686386: Tuple's tp_repr did not take into account the
6002 possibility of having a self-referential tuple, which is possible
6003 from C code. Nor did object's tp_str consider that a type's tp_str
6004 could do something that could lead to an inifinite recursion.
6005 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6006 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006007
Georg Brandl3ee81df2008-05-17 18:14:43 +00006008- Issue #1164: It was possible to trigger deadlock when using the
6009 'print' statement to write to a file since the GIL was not released
6010 as needed. Now PyObject_Print() does the right thing along with
6011 various tp_print implementations of the built-in types and those in
6012 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006013
Georg Brandl3ee81df2008-05-17 18:14:43 +00006014- Issue #1147: Exceptions were directly allowing string exceptions in
6015 their throw() method even though string exceptions no longer
6016 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006017
Georg Brandl3ee81df2008-05-17 18:14:43 +00006018- Issue #1096: Prevent a segfault from getting the repr of a very
6019 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006020
Brett Cannon1e534b52007-09-07 04:18:30 +00006021- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006022 PyObject_Call() never calling back out to Python code to trigger
6023 recursion depth updates/checks. Required the creation of a static
6024 RuntimeError instance in case normalizing an exception put the
6025 recursion check value past its limit. Fixes crashers
6026 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006027
Georg Brandl3ee81df2008-05-17 18:14:43 +00006028- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006041- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006042 __*__ attributes. (Some already existed, e.g., __doc__ and
6043 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006044
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006045- Add -3 option to the interpreter to warn about features that are
6046 deprecated and will be changed/removed in Python 3.0.
6047
Georg Brandl2134e752007-05-21 20:34:16 +00006048- Patch #1686487: you can now pass any mapping after '**' in function
6049 calls.
6050
Collin Winter62903052007-05-18 23:11:24 +00006051- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006052 "except E as target:". This is to provide forwards compatibility
6053 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006054
Brett Cannon229cee22007-05-05 01:34:02 +00006055- Deprecate BaseException.message as per PEP 352.
6056
Georg Brandl3ee81df2008-05-17 18:14:43 +00006057- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006058 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006059
Vinay Sajip8549ce32007-05-06 17:53:37 +00006060- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006061 setting a plain string, ie don't expand to single letter identifiers.
6062
Raymond Hettinger13936692007-04-11 18:40:58 +00006063- Request #1191699: Slices can now be pickled.
6064
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006065- Request #1193128: str.translate() now allows a None argument for
6066 translations that only remove characters without re-mapping the
6067 remaining characters.
6068
Georg Brandl5cb76c12007-03-21 09:00:39 +00006069- Patch #1682205: a TypeError while unpacking an iterable is no longer
6070 masked by a generic one with the message "unpack non-sequence".
6071
Neal Norwitzaa754b72007-03-21 06:39:48 +00006072- Remove unused file Python/fmod.c.
6073
Guido van Rossum143b5642007-03-23 04:58:42 +00006074- Bug #1683368: The object.__init__() and object.__new__() methods are
6075 now stricter in rejecting excess arguments. The only time when
6076 either allows excess arguments is when it is not overridden and the
6077 other one is. For backwards compatibility, when both are
6078 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006079 warning later). Also, type.__init__() insists on the same signature
6080 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006081
Georg Brandl3ee81df2008-05-17 18:14:43 +00006082- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6083 object to complex using its __complex__() method before falling back
6084 to the __float__() method. Therefore, the functions in the cmath
6085 module now can operate on objects that define a __complex__()
6086 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006087
Georg Brandl3ee81df2008-05-17 18:14:43 +00006088- Patch #1623563: allow __class__ assignment for classes with
6089 __slots__. The old and the new class are still required to have the
6090 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006091
Georg Brandl3ee81df2008-05-17 18:14:43 +00006092- Patch #1642547: Fix an error/crash when encountering syntax errors

6096 ``object.__reduce_ex__()`` is called with an object that is faking
6097 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006098
Georg Brandl3ee81df2008-05-17 18:14:43 +00006099- Patch #1680015: Don't modify __slots__ tuple if it contains an

6103
Georg Brandl7b9c5552007-03-12 14:30:05 +00006104- Bug #1678647: write a newline after printing an exception in any
6105 case, even when converting the value to a string failed.
6106
Georg Brandl871f1bc2007-03-12 13:17:36 +00006107- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006108 its argument, if it exists. If not, it will work like before. This
6109 allows customizing the output of dir() in the presence of a
6110 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006118- Patch #1491866: change the complex() constructor to allow
6119 parthensized forms. This means complex(repr(x)) now works instead of
6120 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006121
Georg Brandlaa2321b2007-03-07 00:40:28 +00006122- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006123 makes the filenames the warning module prints much more sensible
6124 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006125

6127 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006128 variable is given, but break into the interactive interpreter just
6129 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006137- Patch #1674228: when assigning a slice (old-style), check for the
6138 sq_ass_slice instead of the sq_slice slot.
6139
Georg Brandl3ee81df2008-05-17 18:14:43 +00006140- When printing an unraisable error, don't print exceptions. before
6141 the name. This duplicates the behavior whening normally printing
6142 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006644- Added a timeout parameter to the constructor of other protocols
6645 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6646 work started with create_connection() and timeout in httplib, and
6647 closes patch #723312.
6648

Georg Brandl3ee81df2008-05-17 18:14:43 +00006675 AttributeError instead of an IOError when the server's response
6676 didn't contain a valid HTTP status line.

6708
Georg Brandl92a6bae2007-03-13 17:43:32 +00006709- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006710 are set for invalid interpolation sequences that would lead to
6711 errors on reading back those values.

6754 returned string up to the first NUL character.

6765
Georg Brandl3ee81df2008-05-17 18:14:43 +00006766- unittest now verifies more of its assumptions. In particular,
6767 TestCase and TestSuite subclasses (not instances) are no longer
6768 accepted in TestSuite.addTest(). This should cause no
6769 incompatibility since it never made sense with ordinary subclasses
6770 -- the failure just occurred later, with a more cumbersome
6771 exception.

6781
Georg Brandl3ee81df2008-05-17 18:14:43 +00006782- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00007160 time so that opening a database previously created with the DB_DUP
7161 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7162 opens. Specifically: dictionary assignment to a DB object will
7163 replace all values for a given key when the database allows
7164 duplicate values. DB users should use DB.put(k, v) when they want
7165 to store duplicates; not DB[k] = v.

7172 characters with ASCII value less than 32. Also, it correctly quotes
7173 dots only if they occur on a single line, as opposed to the previous
7174 behavior of quoting dots if they are the second character of any
7175 line.
