131
Ned Deily87e82bb2011-06-28 19:52:59 -0700132- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
133 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
134 interpreter process. This could cause failures in non-Distutils subprocesses
135 and was unreliable since tests or user programs could modify the interpreter
136 environment after Distutils set it. Instead, have Distutils set the the
137 deployment target only in the environment of each build subprocess. It is
138 still possible to globally override the default by setting
139 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
140 greater or equal to the default value, the value with which the interpreter
141 was built.

147 Kitada.
148
R David Murrayf1138bb2011-06-17 22:23:04 -0400149- Issue #11700: mailbox proxy object close methods can now be called multiple
150 times without error, and _ProxyFile now closes the wrapped file.
151
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200152- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
153 connection if its getresponse() method fails with a socket error. Patch
154 written by Ezio Melotti.
155
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500156- Issue #9284: Allow inspect.findsource() to find the source of doctest
157 functions.
158
R David Murray873c5832011-06-09 16:01:09 -0400159- Issue #10694: zipfile now ignores garbage at the end of a zipfile.

168
Barry Warsawc5643282011-07-19 17:06:30 -0400169- sys.setcheckinterval() now updates the current ticker count as well as
170 updating the check interval, so if the user decreases the check interval,
171 the ticker doesn't have to wind down to zero from the old starting point
172 before the new interval takes effect. And if the user increases the
173 interval, it makes sure the new limit takes effect right away rather have an
174 early task switch before recognizing the new interval.

1032 This prevents user-created self-referencing ordered dictionaries from
1033 becoming permanently uncollectable GC garbage. The downside is that
1034 removing __del__ means that the internal doubly-linked list has to wait for
1035 GC collection rather than freeing memory immediately when the refcnt drops
1036 to zero.

1494
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001495- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1496 start byte and the continuation byte(s) are now considered invalid, instead
1497 of the number of bytes specified by the start byte.
1498 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1499 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1500 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1501 Previous versions returned a single u'\ufffd'.
1502
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001503- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001504 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1505 arises from the "Overriding __eq__ blocks inheritance ..." warning
1506 when turned into an exception: in this case the exception simply
1507 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001508
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001509- Issue #8748: Fix two issues with comparisons between complex and integer
1510 objects. (1) The comparison could incorrectly return True in some cases
1511 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1512 (2) The comparison raised an OverflowError for large integers, leading
1513 to unpredictable exceptions when combining integers and complex objects
1514 in sets or dicts.
1515
Mark Dickinson81336372010-05-30 12:12:25 +00001516- Issue #5211: Implicit coercion for the complex type is now completely
1517 removed. (Coercion for arithmetic operations was already removed in 2.7
1518 alpha 4, but coercion for rich comparisons was accidentally left in.)
1519
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001520- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
1521 and error handler, instead of writing to the C stderr file in utf-8
1522
Georg Brandlfee0f442010-05-22 21:26:21 +00001523- Issue #7902: When using explicit relative import syntax, don't try implicit
1524 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00001525

1527 from another thread. Patch by Daniel Stutzbach.

Victor Stinnerb65bd2e2010-06-11 19:22:28 +00001529- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00001530 Window Server again in a framework build on MacOSX 10.5 or earlier.

Georg Brandlfee0f442010-05-22 21:26:21 +00001535- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
1536 of the interpreter to set sys.argv without also modifying sys.path. This
1537 helps fix `CVE-2008-5983

Georg Brandlfee0f442010-05-22 21:26:21 +00001896- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1897 with a non-empty format string. This is an effort to future-proof user
1898 code. If a derived class does not currently implement __format__ but later
1899 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001900 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001901 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001951- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1952 InvalidOperation instead of returning False. (Comparisons involving a quiet
1953 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1954 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001956- Issue #2531: Comparison operations between floats and Decimal instances now
1957 return a result based on the numeric values of the operands; previously they

1975 makes Fraction <=> complex comparisons consistent with int <=> complex, float

Georg Brandlba83f822010-03-14 09:50:54 +00002338- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2339 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2340 returning NULL. The macro now returns a statically allocated empty string
2341 instead.

2351 strings,
2352 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2353 numeric strings corresponding to subnormal values,
2354 (3) a memory leak for some values large enough to cause overflow, and
2355 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002386- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002387 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002388 Also, raise ValueError rather than TypeError when an unknown TIPC address
2389 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002393- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002394 file position when calling `truncate()`. It would previously change the file
2395 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002396 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2397

2399 class used to represent files stored inside an archive. The new
2400 implementation is significantly faster and can be wrapped in a
2401 ``io.BufferedReader`` object for more speedups. It also solves an issue
2402 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2403 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002413- Issue #7748: Since unicode values are supported for some metadata options in
2414 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2415 encoded string for them. This ensures that the upload and register commands
2416 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002687- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2688 decimal string that's guaranteed to round back to x under correct rounding
2689 (with round-half-to-even rounding mode). Previously it gave a string based on
2690 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2691 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2692 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002694- Issue #7117: On almost all platforms: float-to-string and string-to-float
2695 conversions within Python are now correctly rounded. Places these conversions
2696 occur include: str for floats and complex numbers; the float and complex
2697 constructors; old-style and new-style numeric formatting; serialization and
2698 deserialization of floats and complex numbers using marshal, pickle and json;
2699 parsing of float and imaginary literals in Python code; Decimal-to-float
2700 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002701
Georg Brandlba83f822010-03-14 09:50:54 +00002702 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2703 providing correctly-rounded strtod and dtoa C functions. This code is
2704 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2705 the C compiler. There may be a small number of platforms on which correct
2706 operation of this code cannot be guaranteed, so the code is not used: notably,
2707 this applies to platforms where the C double format is not IEEE 754 binary64,
2708 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2709 and Python's configure script is unable to determine how to change the FPU
2710 precision. On these platforms conversions use the platform strtod and dtoa,
2711 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002713- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2714 uses the correctly-rounded string <-> float conversions described above (when
2715 available), and so produces correctly rounded results that will display nicely
2716 under the float repr. There are two related small changes: (1) round now
2717 accepts any class with an ``__index__()`` method for its second argument (but
2718 no longer accepts floats for the second argument), and (2) an excessively
2719 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2720 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002938 untrackable objects are not tracked by the garbage collector. This can reduce
2939 the size of collections and therefore the garbage collection overhead on
2940 long-running programs, depending on their particular use of datatypes.

2947 internal representation of integers, for performance reasons. Base 2**30 is
2948 enabled by default on 64-bit machines. Add --enable-big-digits option to

2981
Georg Brandl29c6a282009-04-05 20:23:13 +00002982- Issue #1242657: the __len__() and __length_hint__() calls in several tools

Georg Brandlba83f822010-03-14 09:50:54 +00003013- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3014 existing .py counterpart, override the co_filename attributes of all code

3070
Georg Brandlba83f822010-03-14 09:50:54 +00003071- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3072 file objects with closefd=False. The file descriptor is still kept open but
3073 the file object behaves like a closed file. The ``FileIO`` object also got a
3074 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00003097- On windows, ``os.chdir()`` given unicode was not working if

3099 this code path is really executed because I cannot move to such directory on

Walter Dörwalded960ac2009-05-03 22:36:33 +00003125- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3126 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3127 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3128 of using the replace error handler in PyUnicode_DecodeUTF8().
3129
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003130- Issue #3739: The unicode-internal encoder now reports the number of characters

3135 gives improved memory leak detection when running under Valgrind, while taking
3136 advantage of pymalloc at other times.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004503- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

4505 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4506 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00004604 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4605 for catch_warnings() also led to an improvement in the raising of a
4606 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004672What's New in Python 2.6 beta 3?
4673================================
4674
Barry Warsaw07a4a382008-08-21 01:15:08 +00004675*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004676
4677Core and Builtins
4678-----------------
4679
Guido van Rossumf8402962008-08-20 15:01:50 +00004680- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4681 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4682 extensions do not automatically benefit from the class attribute
4683 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4684 to their tp_flags field if they care. This is a backwards
4685 compatibility feature; in 3.0, all types will use the cache by
4686 default.
4687
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004688- Keyword arguments can now follow starred arguments. (``f(a, *args,
4689 keyword=23)`` is now valid syntax.)
4690
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004691- ctypes function pointers that are COM methods have a boolean True
4692 value again.
4693
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004694- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4695 by denying s# to parse objects that have a releasebuffer procedure,
4696 and introducing s*.
4697
Georg Brandl1e13ea92008-08-11 09:07:59 +00004698- Issue #3537: Fix an assertion failure when an empty but presized dict
4699 object was stored in the freelist.
4700
Mark Dickinsonb6467572008-08-04 21:30:09 +00004701- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4702 ValueError consistently across platforms.
4703
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004704- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4705 (64bit Unix, for example), unichr() would truncate its argument and return
4706 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4707
Neal Norwitze7d8be82008-07-31 17:17:14 +00004708- Apply security patches from Apple.
4709
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004710- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4711 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4712
Antoine Pitrou92f82162008-07-25 22:22:08 +00004713- Issue #1819: function calls with several named parameters are now on
4714 average 35% faster (as measured by pybench).
4715
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004716- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4717 the python debugger steps into a class statement: the free variables (local
4718 variables defined in an outer scope) would be deleted from the outer scope.
4719
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004720- Issue #2620: Overflow checking when allocating or reallocating memory
4721 was not always being done properly in some python types and extension
4722 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4723 all been updated to perform better checks and places in the code that
4724 would previously leak memory on the error path when such an allocation
4725 failed have been fixed.

4728-------
4729
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004730- Issue #3612: Added some missing basic types in ctypes.wintypes.
4731
Benjamin Petersone977ad42008-08-20 01:42:01 +00004732- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4733 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4734
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004735- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4736 version reported by these tools does not necessarily follow the python
4737 version numbering scheme, so the module is less strict when parsing it.
4738
Nick Coghlanf70385a2008-08-18 12:42:46 +00004739- Issue #2235: Added Py3k warnings for types which will become unhashable
4740 under the stricter __hash__ inheritance rules in 3.0. Several types
4741 which did not meet the rules for hash invariants and were already
4742 unhashable in 3.0 have now been explicitly flagged as unhashable in
4743 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4744 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4745
Brett Cannon88f801d2008-08-18 00:46:22 +00004746- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4747 imported into the module but exposed as part of the module's API.
4748
Brett Cannon7b96f072008-08-18 00:41:11 +00004749- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4750
Brett Cannon46225e72008-08-18 00:36:52 +00004751- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004753- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4754
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004755- Issue #3575: Incremental decoder's decode function now takes bytearray
4756 by using 's*' instead of 't#'.
4757
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004758- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004759 fails unicode conversion on 2nd parameter. (windows only)
4760
Georg Brandl222e2082010-08-01 22:27:39 +00004761- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004762 in a redirect.
4763
Brett Cannonabe423e2008-08-16 21:47:07 +00004764- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004765 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004766
Facundo Batistaeb90b782008-08-16 14:44:07 +00004767- Issue #2776: fixed small issue when handling an URL with double slash
4768 after a 302 response in the case of not going through a proxy.
4769
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004770- Issue #2676: in the email package, content-type parsing was hanging on
4771 pathological input because of quadratic or exponential behaviour of a
4772 regular expression.
4773
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004774- Issue #3476: binary buffered reading through the new "io" library is now
4775 thread-safe.
4776
Brett Cannonbf3157b2008-08-14 05:00:03 +00004777- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4778 since mimetools itself is deprecated. Because modules are cached, all
4779 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4780
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004781- Issue #3134: shutil referenced undefined WindowsError symbol.
4782
Robert Schuppenies14646332008-08-10 11:01:53 +00004783- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4784 menu entries were not deleted.
4785
Brett Cannon83e81842008-08-09 23:30:55 +00004786- Copied the implementation of reduce() to _functools.reduce() to have a
4787 version that did not raise a DeprecationWarning under -3.
4788
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004789- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4790 a MemoryError rather than silently stop the iteration.
4791
Guido van Rossum59ce9012008-08-09 14:55:34 +00004792- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4793 to _sre.compile() will now be rejected. This should not affect anybody
4794 since the re.compile() function never generates invalid re-bytecode.
4795
Skip Montanaroa032bf42008-08-08 22:52:51 +00004796- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4797 upon first access it can be automatically initialized from the csv file if
4798 it wasn't initialized during instantiation.
4799
Brett Cannon3aa2a492008-08-06 22:28:09 +00004800- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4801 the reload() built-in has been removed.
4802
Brett Cannon7e30b672008-08-04 21:52:25 +00004803- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004804 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004815 asking for a specific length. This problem only affected files opened
4816 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004817
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004818- Issue #3449: Update decimal module to use most recent specification
4819 (v. 1.68) and tests (v. 2.58) from IBM.

4872-----------------
4873
Georg Brandl3e483f62008-07-16 22:57:41 +00004874- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4875 its methods now allow for items objects that can be converted to
4876 an integer using operator.index().
4877
Mark Dickinson64b7e502008-07-16 09:40:03 +00004878- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4879 produced a ValueError instead of giving the correct float.
4880
Eric Smitha5fa5a22008-07-16 00:11:49 +00004881- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4882 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4883
Mark Dickinson7103aa42008-07-15 19:08:33 +00004884- Issue #3008: the float type has a new instance method 'float.hex'
4885 and a new class method 'float.fromhex' to convert floating-point
4886 numbers to and from hexadecimal strings, respectively.
4887
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004888- Issue #2235: __hash__ is once again inherited by default. To allow
4889 collections.Hashable to remain meaningful in the presence of the
4890 default hash implementation (object.__hash__), it is now possible
4891 to explicit block inheritance of hash by setting __hash__=None at
4892 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4893 level.
4894
Nick Coghlanb028f502008-07-13 14:52:36 +00004895- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4896 the parent module cannot be found while performing an absolute import.
4897 This means that an incorrectly defined __package__ attribute will
4898 now only prevent relative imports in that module rather than causing
4899 all imports from that module to fail.
4900
Nick Coghlan14ff9942008-07-08 14:21:42 +00004901- Issue #2517: Allow unicode messages in Exceptions again by correctly

4911 another thread's dictionary.
4912
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004913- Issue #3004: Minor change to slice.indices(): the start and stop
4914 arguments are now treated identically, making the behaviour easier
4915 to describe and understand. For example, slice(None, -10,
4916 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4917 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4918 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00004920- Issue #3219: Calling a function with repeated keyword arguments,
4921 f(a=2, a=23), would not cause a syntax error. This was a regression
4922 from 2.4 caused by the switch to the new compiler.

4932 api functions without holding the GIL, which could lead to a fatal
4933 error when they failed.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004960- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4961 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004962 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004963 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004979- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005434- Issue #1631171: Re-implement the 'warnings' module in C (the
5435 original Python code has been kept as backup). This will allow for
5436 using the 'warning's machinery in such places as the parser where
5437 use of pure Python code is not possible. Both the ``showarning()``
5438 and ``formatwarning()`` gain an optional 'line' argument which is
5439 not called by default for backwards-compatibility reasons. Setting
5440 ``warnings.showwarning()`` to an implementation that lacks support
5441 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005483- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005484 extension modules between 32 and 64 bit platforms. See the distutls

5497 so the controlled environment will more closely mirror the typical
5498 script environment. This supports setup.py scripts that refer to
5499 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005504- Issue #2550: The approach used by client/server code for obtaining
5505 ports to listen on in network-oriented tests has been refined in an
5506 effort to facilitate running multiple instances of the entire
5507 regression test suite in parallel without issue.
5508 test_support.bind_port() has been fixed such that it will always
5509 return a unique port -- which wasn't always the case with the
5510 previous implementation, especially if socket options had been set
5511 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5512 new implementation of bind_port() will actually raise an exception
5513 if it is passed an AF_INET/SOCK_STREAM socket with either the
5514 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5515 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5516 the socket it's been passed. This currently only applies to
5517 Windows. This option prevents any other sockets from binding to the
5518 host/port we've bound to, thus removing the possibility of the
5519 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5520 when a second SOCK_STREAM socket binds and accepts to a host/port
5521 that's already been bound by another socket. The optional preferred
5522 port parameter to bind_port() has been removed. Under no
5523 circumstances should tests be hard coding ports!
5524
5525 test_support.find_unused_port() has also been introduced, which will
5526 pass a temporary socket object to bind_port() in order to obtain an
5527 unused port. The temporary socket object is then closed and
5528 deleted, and the port is returned. This method should only be used
5529 for obtaining an unused port in order to pass to an external program
5530 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5531 a parameter to a server-oriented class that doesn't give you direct
5532 access to the underlying socket used.
5533
5534 Finally, test_support.HOST has been introduced, which should be used
5535 for the host argument of any relevant socket calls (i.e. bind and
5536 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005537
5538 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005539 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005540 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5541 test_asynchat and test_socket_ssl.
5542
Georg Brandl3ee81df2008-05-17 18:14:43 +00005543 It is now possible for multiple instances of the regression test
5544 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005823- Added the future_builtins module, which contains hex() and oct().
5824 These are the PEP 3127 version of these functions, designed to be
5825 compatible with the hex() and oct() builtins from Python 3.0. They
5826 differ slightly in their output formats from the existing, unchanged
5827 Python 2.6 builtins. The expected usage of the future_builtins
5828 module is:
5829 from future_builtins import hex, oct
5830
Eric Smith7ef40bf2008-02-20 23:34:22 +00005831- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5832 exponents for exponents with absolute value < 100. Follows C99
5833 standard. This is a change on Windows, which would use 3 digits.
5834 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5835 so that any alterations it does to the resulting string will be
5836 available in stringlib/formatter.h (for float.__format__).
5837
Eric Smith5a3c1352008-02-19 13:21:56 +00005838- Implemented PEP 3101, Advanced String Formatting. This adds a new
5839 builtin format(); a format() method for str and unicode; a
5840 __format__() method to object, str, unicode, int, long, float, and
5841 datetime; the class string.Formatter; and the C API
5842 PyObject_Format().
5843
Georg Brandl3ee81df2008-05-17 18:14:43 +00005844- Fixed several potential crashes, all caused by specially crafted
5845 __del__ methods exploiting objects in temporarily inconsistent
5846 state.

5890 the same object as the func_code attribute of the function that
5891 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005892
Georg Brandl3ee81df2008-05-17 18:14:43 +00005893- Issue #1920: "while 0" statements were completely removed by the
5894 compiler, even in the presence of an "else" clause, which is
5895 supposed to be run when the condition is false. Now the compiler
5896 correctly emits bytecode for the "else" suite.

Christian Heimes082c9b02008-01-23 14:20:50 +00005907 several extension methods and modules do not work without unicode
5908 support.
5909
Georg Brandl26543b12008-01-21 18:36:51 +00005910- Issue #1882: when compiling code from a string, encoding cookies in the
5911 second line of code were not always recognized correctly.
5912
Georg Brandl14404b62008-01-19 19:27:05 +00005913- Issue #1679: "0x" was taken as a valid integer literal.
5914
Georg Brandl6caad7d2008-01-26 14:19:22 +00005915- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005916 added.
5917
Christian Heimesc94e2b52008-01-14 04:13:37 +00005918- sys.float_info / PyFloat_GetInfo: The floating point information
5919 object was converted from a dict to a specialized structseq object.
5920
Georg Brandl3ee81df2008-05-17 18:14:43 +00005921- Patch #1816: Added sys.flags structseq. It exposes the status of
5922 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005923
Georg Brandl3ee81df2008-05-17 18:14:43 +00005924- Objects/structseq.c: Implemented new structseq representation. The
5925 patch makes structseqs (e.g. the return value of os.stat) more
5926 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005927
Georg Brandl3ee81df2008-05-17 18:14:43 +00005928- Patch #1700288: added a type attribute cache that caches method
5929 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005930
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005931- Bug #1776: __import__() no longer accepts filenames on any platform.
5932 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005933
Georg Brandlaed6c662008-01-07 17:25:53 +00005934- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5935
Georg Brandl3ee81df2008-05-17 18:14:43 +00005936- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5937 envvar and sys.dont_write_bytecode attribute. All these can be set
5938 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005939
Georg Brandl3ee81df2008-05-17 18:14:43 +00005940- Improve some exception messages when Windows fails to load an
5941 extension module. Now we get for example '%1 is not a valid Win32
5942 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005943
Georg Brandl3ee81df2008-05-17 18:14:43 +00005944- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005946- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5947 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005948
Christian Heimes0a8143f2007-12-18 23:22:54 +00005949- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005950 and INF. float("nan"), float("inf") and float("-inf") now work on
5951 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005952
Georg Brandl3ee81df2008-05-17 18:14:43 +00005953- Compiler now generates simpler and faster code for dictionary
5954 literals. The oparg for BUILD_MAP now indicates an estimated
5955 dictionary size. There is a new opcode, STORE_MAP, for adding
5956 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005966- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005967 SystemError.
5968
Nick Coghlanef01d822007-12-03 12:55:17 +00005969- PEP 366: Allow explicit relative imports when executing modules
5970 inside packages with the -m switch via a new module level
5971 __package__ attribute.

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005980 attribute of an empty cell object.
5981
Georg Brandl3ee81df2008-05-17 18:14:43 +00005982- Issue #1460: The utf-7 incremental decoder did not accept truncated
5983 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005984
Georg Brandl3ee81df2008-05-17 18:14:43 +00005985- Patch #1739468: Directories and zipfiles containing a __main__.py
5986 file can now be directly executed by passing their name to the
5987 interpreter. The directory/zipfile is automatically inserted as the
5988 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005989
Georg Brandl3ee81df2008-05-17 18:14:43 +00005990- Issue #1265: Fix a problem with sys.settrace, if the tracing
5991 function uses a generator expression when at the same time the
5992 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005993
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005994- sets and frozensets now have an isdisjoint() method.
5995
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005996- optimize the performance of builtin.sum().
5997
Neal Norwitz44f326e2007-10-05 05:29:17 +00005998- Fix warnings found by the new version of the Coverity checker.
5999
Georg Brandl21e99f42010-03-07 15:23:59 +00006000- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006001 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6002 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006003
Georg Brandl3ee81df2008-05-17 18:14:43 +00006004- Issue #1686386: Tuple's tp_repr did not take into account the
6005 possibility of having a self-referential tuple, which is possible
6006 from C code. Nor did object's tp_str consider that a type's tp_str
6007 could do something that could lead to an inifinite recursion.
6008 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6009 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006010
Georg Brandl3ee81df2008-05-17 18:14:43 +00006011- Issue #1164: It was possible to trigger deadlock when using the
6012 'print' statement to write to a file since the GIL was not released
6013 as needed. Now PyObject_Print() does the right thing along with
6014 various tp_print implementations of the built-in types and those in
6015 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006016
Georg Brandl3ee81df2008-05-17 18:14:43 +00006017- Issue #1147: Exceptions were directly allowing string exceptions in
6018 their throw() method even though string exceptions no longer
6019 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006020
Georg Brandl3ee81df2008-05-17 18:14:43 +00006021- Issue #1096: Prevent a segfault from getting the repr of a very
6022 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006023
Brett Cannon1e534b52007-09-07 04:18:30 +00006024- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006025 PyObject_Call() never calling back out to Python code to trigger
6026 recursion depth updates/checks. Required the creation of a static
6027 RuntimeError instance in case normalizing an exception put the
6028 recursion check value past its limit. Fixes crashers
6029 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006030
Georg Brandl3ee81df2008-05-17 18:14:43 +00006031- Patch #1031213: Decode source line in SyntaxErrors back to its

6035 with %G.
6036
Georg Brandl3ee81df2008-05-17 18:14:43 +00006037- Prevent expandtabs() on string and unicode objects from causing a
6038 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006039

Neal Norwitz0ac60192007-05-27 04:08:54 +00006044- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006045 __*__ attributes. (Some already existed, e.g., __doc__ and
6046 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006047
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006048- Add -3 option to the interpreter to warn about features that are
6049 deprecated and will be changed/removed in Python 3.0.
6050
Georg Brandl2134e752007-05-21 20:34:16 +00006051- Patch #1686487: you can now pass any mapping after '**' in function
6052 calls.
6053
Collin Winter62903052007-05-18 23:11:24 +00006054- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006055 "except E as target:". This is to provide forwards compatibility
6056 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006057
Brett Cannon229cee22007-05-05 01:34:02 +00006058- Deprecate BaseException.message as per PEP 352.
6059
Georg Brandl3ee81df2008-05-17 18:14:43 +00006060- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006061 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006062
Vinay Sajip8549ce32007-05-06 17:53:37 +00006063- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006064 setting a plain string, ie don't expand to single letter identifiers.
6065
Raymond Hettinger13936692007-04-11 18:40:58 +00006066- Request #1191699: Slices can now be pickled.
6067
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006068- Request #1193128: str.translate() now allows a None argument for
6069 translations that only remove characters without re-mapping the
6070 remaining characters.
6071
Georg Brandl5cb76c12007-03-21 09:00:39 +00006072- Patch #1682205: a TypeError while unpacking an iterable is no longer
6073 masked by a generic one with the message "unpack non-sequence".
6074
Neal Norwitzaa754b72007-03-21 06:39:48 +00006075- Remove unused file Python/fmod.c.
6076
Guido van Rossum143b5642007-03-23 04:58:42 +00006077- Bug #1683368: The object.__init__() and object.__new__() methods are
6078 now stricter in rejecting excess arguments. The only time when
6079 either allows excess arguments is when it is not overridden and the
6080 other one is. For backwards compatibility, when both are
6081 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006082 warning later). Also, type.__init__() insists on the same signature
6083 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006084
Georg Brandl3ee81df2008-05-17 18:14:43 +00006085- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6086 object to complex using its __complex__() method before falling back
6087 to the __float__() method. Therefore, the functions in the cmath
6088 module now can operate on objects that define a __complex__()
6089 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006090
Georg Brandl3ee81df2008-05-17 18:14:43 +00006091- Patch #1623563: allow __class__ assignment for classes with
6092 __slots__. The old and the new class are still required to have the
6093 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006094
Georg Brandl3ee81df2008-05-17 18:14:43 +00006095- Patch #1642547: Fix an error/crash when encountering syntax errors
6096 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006098- Patch #1462488: Python no longer segfaults when
6099 ``object.__reduce_ex__()`` is called with an object that is faking
6100 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006101
Georg Brandl3ee81df2008-05-17 18:14:43 +00006102- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00006105- Patch #1444529: the builtin compile() now accepts keyword arguments.
6106
Georg Brandl7b9c5552007-03-12 14:30:05 +00006107- Bug #1678647: write a newline after printing an exception in any
6108 case, even when converting the value to a string failed.
6109
Georg Brandl871f1bc2007-03-12 13:17:36 +00006110- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006111 its argument, if it exists. If not, it will work like before. This
6112 allows customizing the output of dir() in the presence of a
6113 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006114
Collin Winter276887b2007-03-12 16:11:39 +00006115- Patch #922167: Python no longer segfaults when faced with infinitely
6116 self-recursive reload() calls (as reported by bug #742342).
6117
Georg Brandl3ee81df2008-05-17 18:14:43 +00006118- Patch #1675981: remove unreachable code from ``type.__new__()``
6119 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006121- Patch #1491866: change the complex() constructor to allow
6122 parthensized forms. This means complex(repr(x)) now works instead of
6123 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006124
Georg Brandlaa2321b2007-03-07 00:40:28 +00006125- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006126 makes the filenames the warning module prints much more sensible
6127 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006128
Georg Brandl49aafc92007-03-07 00:34:46 +00006129- Variant of patch #697613: don't exit the interpreter on a SystemExit
6130 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006131 variable is given, but break into the interactive interpreter just
6132 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006137- Bug #1674503: close the file opened by execfile() in an error
6138 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00006139
Georg Brandl0fca97a2007-03-05 22:28:08 +00006140- Patch #1674228: when assigning a slice (old-style), check for the
6141 sq_ass_slice instead of the sq_slice slot.
6142
Georg Brandl3ee81df2008-05-17 18:14:43 +00006143- When printing an unraisable error, don't print exceptions. before
6144 the name. This duplicates the behavior whening normally printing

Facundo Batistad918a652007-04-24 13:54:38 +00006636- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006637 the client's request was successfully received, understood, and
6638 accepted. Now in these cases no error is raised in urllib (issue
6639 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006647- Added a timeout parameter to the constructor of other protocols
6648 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6649 work started with create_connection() and timeout in httplib, and
6650 closes patch #723312.
6651
Vinay Sajip8549ce32007-05-06 17:53:37 +00006652- Patch #1676823: Added create_connection() to socket.py, which may be
6653 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006654 and HTTPSConnection now accept an optional timeout).

Georg Brandl3ee81df2008-05-17 18:14:43 +00006678 AttributeError instead of an IOError when the server's response
6679 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006685- Patch #1429539: pdb now correctly initializes the __main__ module
6686 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006687 correctly now.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006696- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00006709- Patch #1581073: add a flag to textwrap that prevents the dropping of
6710 whitespace while wrapping.
6711
Georg Brandl92a6bae2007-03-13 17:43:32 +00006712- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006713 are set for invalid interpolation sequences that would lead to
6714 errors on reading back those values.

6757 returned string up to the first NUL character.

6768
Georg Brandl3ee81df2008-05-17 18:14:43 +00006769- unittest now verifies more of its assumptions. In particular,
6770 TestCase and TestSuite subclasses (not instances) are no longer
6771 accepted in TestSuite.addTest(). This should cause no
6772 incompatibility since it never made sense with ordinary subclasses
6773 -- the failure just occurred later, with a more cumbersome
6774 exception.

6783 given a unicode argument and os.listdir() returns unicode filenames.
6784
Georg Brandl3ee81df2008-05-17 18:14:43 +00006785- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00007163 time so that opening a database previously created with the DB_DUP
7164 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7165 opens. Specifically: dictionary assignment to a DB object will
7166 replace all values for a given key when the database allows
7167 duplicate values. DB users should use DB.put(k, v) when they want
7168 to store duplicates; not DB[k] = v.

7175 characters with ASCII value less than 32. Also, it correctly quotes
7176 dots only if they occur on a single line, as opposed to the previous
7177 behavior of quoting dots if they are the second character of any
7178 line.
