1104
1105- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1106 and later systems as is currently done for Python 3.x installers.
1107 For 2.7.7 only, we will provide three installers:
1108 the legacy deprecated 10.3+ 32-bit-only format;
1109 the newer 10.5+ 32-bit-only format;
1110 and the unchanged 10.6+ 64-/32-bit format.
1111 Although binary installers will no longer be available from
1112 python.org as of 2.7.8, it will still be possible to build from
1113 source on 10.3.9 and 10.4 systems if necessary.
1114 See Mac/BuildScript/README.txt for more information.

2496 32-bit-only installer Pythons on systems with Xcode 4 (currently
2497 OS X 10.8, 10.7, and optionally 10.6).
2498 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2499 * Since Xcode 4 removes ppc support, extension module builds now
2500 check for ppc compiler support and by default remove ppc and
2501 ppc64 archs when they are not available.
2502 * Extension module builds now revert to using system installed
2503 headers and libs (/usr and /System/Library) if the SDK used
2504 to build the interpreter is not installed or has moved.
2505 * Try to avoid building extension modules with deprecated
2506 and problematic Apple llvm-gcc compiler. If original compiler
2507 is not available, use clang instead by default.

2875 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01002951- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2952 Distutils-based packages with C extension modules may fail because
2953 Apple has removed gcc-4.2, the version used to build python.org
2954 64-bit/32-bit Pythons. If the user does not explicitly override
2955 the default C compiler by setting the CC environment variable,
2956 Distutils will now attempt to compile extension modules with clang
2957 if gcc-4.2 is required but not found. Also as a convenience, if
2958 the user does explicitly set CC, substitute its value as the default
2959 compiler in the Distutils LDSHARED configuration variable for OS X.
2960 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2961 SDK, neither of which are available in Xcode 4. This change does not
2962 attempt to override settings to support their use with Xcode 4.)

Victor Stinner08563d92011-05-30 23:44:13 +02003115
Lars Gustäbel8babfdf2011-09-05 17:04:18 +02003116- Issue #12841: tarfile unnecessarily checked the existence of numerical user
3117 and group ids on extraction. If one of them did not exist the respective id
3118 of the current user (i.e. root) was used for the file and ownership

Ned Deily87e82bb2011-06-28 19:52:59 -07003212- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3213 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3214 interpreter process. This could cause failures in non-Distutils subprocesses
3215 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003216 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003217 deployment target only in the environment of each build subprocess. It is
3218 still possible to globally override the default by setting
3219 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3220 greater or equal to the default value, the value with which the interpreter
3221 was built.
3222

3248
Barry Warsawc5643282011-07-19 17:06:30 -04003249- sys.setcheckinterval() now updates the current ticker count as well as
3250 updating the check interval, so if the user decreases the check interval,
3251 the ticker doesn't have to wind down to zero from the old starting point
3252 before the new interval takes effect. And if the user increases the
3253 interval, it makes sure the new limit takes effect right away rather have an
3254 early task switch before recognizing the new interval.

4241 by Andrew Bennetts.

4250
Raymond Hettinger20397532010-09-12 02:11:45 +00004251- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4252 This prevents user-created self-referencing ordered dictionaries from
4253 becoming permanently uncollectable GC garbage. The downside is that
4254 removing __del__ means that the internal doubly-linked list has to wait for
4255 GC collection rather than freeing memory immediately when the refcnt drops
4256 to zero.
4257
Raymond Hettingerffd2a422010-09-10 10:47:22 +00004258- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

4261
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004262- Issue #9792: In case of connection failure, socket.create_connection()
4263 would swallow the exception and raise a new one, making it impossible
4264 to fetch the original errno, or to filter timeout errors. Now the
4265 original error is re-raised.
4266
Antoine Pitrouf4f61712010-09-07 16:34:47 +00004267- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
4268 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
4269 be updated back after the system call. Original patch by Brian Brazil.

4276
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00004277- Issue #808164: Fixed socket.close to avoid references to globals, to
4278 avoid issues when socket.close is called from a __del__ method.
4279

4282 heuristic. Patch by Terry Reedy and Eli Bendersky
4283

4285 falling into recursion.
4286
R. David Murray7c4bf552010-08-25 01:45:57 +00004287- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
4288 character years even if the message contains RFC822 two character years.
4289
Daniel Stutzbach91287322010-08-24 21:09:30 +00004290- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00004301- Issue #9214: Set operations on KeysView or ItemsView in the collections
4302 module now correctly return a set. (Patch by Eli Bendersky.)
4303
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00004304- Issue #9617: Signals received during a low-level write operation aren't
4305 ignored by the buffered IO layer anymore.
4306
Benjamin Peterson52c36052010-08-21 03:03:22 +00004307- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
4308 are not held onto after they are deleted elsewhere.
4309
Raymond Hettingera54b2da2010-08-17 19:03:06 +00004310- Issue #9626: the view methods for collections.OrderedDict() were returning
4311 the unordered versions inherited from dict. Those methods are now
4312 overridden to provide ordered views.
4313
Éric Araujo0389ae62010-08-14 03:07:46 +00004314- Issue #8688: MANIFEST files created by distutils now include a magic
4315 comment indicating they are generated. Manually maintained MANIFESTs
4316 without this marker will not be overwritten or removed.
4317
Antoine Pitroue1436d12010-08-12 15:25:51 +00004318- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
4319 and a BadZipfile error is raised if it doesn't match (as used to be the
4320 case in Python 2.5 and earlier).
4321
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00004322- Issue #9550: a BufferedReader could issue an additional read when the
4323 original read request had been satisfied, which could block indefinitely
4324 when the underlying raw IO channel was e.g. a socket. Report and original
4325 patch by Jason V. Miller.
4326
Fred Drake0a1fa0e2010-08-10 13:09:54 +00004327- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00004345- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
4346 This is how it is supposed to work, wget and curl do the same. Previous
4347 behavior was wrong.

4355 the option character for the added 'h/help' option if prefix_chars
4356 does not contain a '-', instead of raising an error.
4357

4980 indefinitely if the other end didn't respond.
4981
Georg Brandlfee0f442010-05-22 21:26:21 +00004982- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00005075 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00005100- Issue #7301: Add environment variable $PYTHONWARNINGS.
5101
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00005102- Issue #8329: Don't return the same lists from select.select when no fds are
5103 changed.
5104
Georg Brandlfee0f442010-05-22 21:26:21 +00005105- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005106 on 64-bit machines. The shift count for either left or right shift is
5107 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00005115- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5116 with a non-empty format string. This is an effort to future-proof user
5117 code. If a derived class does not currently implement __format__ but later
5118 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005119 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005120 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00005170- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5171 InvalidOperation instead of returning False. (Comparisons involving a quiet
5172 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5173 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005174
Georg Brandlfee0f442010-05-22 21:26:21 +00005175- Issue #2531: Comparison operations between floats and Decimal instances now
5176 return a result based on the numeric values of the operands; previously they
5177 returned an arbitrary result based on the relative ordering of id(float) and
5178 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00005192- Comparisons using one of <, <=, >, >= between a complex instance and a
5193 Fractions instance now raise TypeError instead of returning True/False. This
5194 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5195 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00005557- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5558 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5559 returning NULL. The macro now returns a statically allocated empty string
5560 instead.

5570 strings,
5571 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5572 numeric strings corresponding to subnormal values,
5573 (3) a memory leak for some values large enough to cause overflow, and
5574 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00005605- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00005606 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005612- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005613 file position when calling `truncate()`. It would previously change the file
5614 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005615 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5616

5618 class used to represent files stored inside an archive. The new
5619 implementation is significantly faster and can be wrapped in a
5620 ``io.BufferedReader`` object for more speedups. It also solves an issue
5621 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00005632- Issue #7748: Since unicode values are supported for some metadata options in
5633 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5634 encoded string for them. This ensures that the upload and register commands
5635 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00005704What's New in Python 2.7 alpha 2?

5710-----------------
5711
Georg Brandlba83f822010-03-14 09:50:54 +00005712- The ``__complex__()`` method is now looked up on the class of instances to
5713 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005714
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005715- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5716 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5717
Mark Dickinson1b34d252010-01-01 17:27:30 +00005718- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005719 DeprecationWarning when passed a float argument where an integer was expected.
5720 These functions and methods now raise TypeError instead. The majority of the
5721 effects of this change are in the extension modules, but some core functions
5722 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5723 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00005724

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00005733- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
5734 used to drop the time part of the result.
5735
Georg Brandlba83f822010-03-14 09:50:54 +00005736- Issue #1811: Improve accuracy and cross-platform consistency for true division
5737 of integers: the result of a/b is now correctly rounded for ints a and b (at
5738 least on IEEE 754 platforms), and in particular does not depend on the
5739 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00005740
Georg Brandlba83f822010-03-14 09:50:54 +00005741- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
5742 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
5743 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00005744

Ronald Oussoren92919a62009-12-24 13:30:58 +00005746 executables on OSX.
5747
Georg Brandlba83f822010-03-14 09:50:54 +00005748 These executables now work properly with the arch(1) command: ``arch -ppc
5749 python`` will start a universal binary version of python in PPC mode (unlike
5750 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00005751
Georg Brandlba83f822010-03-14 09:50:54 +00005752- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

5764 allowing for a maximum number of tasks within the pool to be completed by the
5765 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00005771- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00005772 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
5773 alternative to cPickle if you care about performance. Patch by Florent

Ezio Melotti569e61f2009-12-30 06:14:51 +00005793 Initial patch by Brian Curtin.
5794
Georg Brandlba83f822010-03-14 09:50:54 +00005795- Distutils now correctly identifies the build architecture as "x86_64" when

5809 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
5810 the same as passing no argument.
5811
Georg Brandlba83f822010-03-14 09:50:54 +00005812- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00005905- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5906 decimal string that's guaranteed to round back to x under correct rounding
5907 (with round-half-to-even rounding mode). Previously it gave a string based on
5908 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5909 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5910 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00005912- Issue #7117: On almost all platforms: float-to-string and string-to-float
5913 conversions within Python are now correctly rounded. Places these conversions
5914 occur include: str for floats and complex numbers; the float and complex
5915 constructors; old-style and new-style numeric formatting; serialization and
5916 deserialization of floats and complex numbers using marshal, pickle and json;
5917 parsing of float and imaginary literals in Python code; Decimal-to-float
5918 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005919
Georg Brandlba83f822010-03-14 09:50:54 +00005920 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5921 providing correctly-rounded strtod and dtoa C functions. This code is
5922 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5923 the C compiler. There may be a small number of platforms on which correct
5924 operation of this code cannot be guaranteed, so the code is not used: notably,
5925 this applies to platforms where the C double format is not IEEE 754 binary64,
5926 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5927 and Python's configure script is unable to determine how to change the FPU
5928 precision. On these platforms conversions use the platform strtod and dtoa,
5929 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005931- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5932 uses the correctly-rounded string <-> float conversions described above (when
5933 available), and so produces correctly rounded results that will display nicely
5934 under the float repr. There are two related small changes: (1) round now
5935 accepts any class with an ``__index__()`` method for its second argument (but
5936 no longer accepts floats for the second argument), and (2) an excessively
5937 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5938 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00006156 untrackable objects are not tracked by the garbage collector. This can reduce
6157 the size of collections and therefore the garbage collection overhead on
6158 long-running programs, depending on their particular use of datatypes.

6317 this code path is really executed because I cannot move to such directory on

7544 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
7545 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7546 neither __int__ nor __long__, TypeError used to be raised (with a
7547 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
7548 struct.error in other cases.

7551 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007745- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7746 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7747 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7748 ``printf`` function, whereas PyString_FromFormat has an independent
7749 implementation and uses "%zd" on all platforms for size_t values.

Nick Coghland2e09382008-09-11 12:11:06 +00007819- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00007820 return a list or None rather than a custom object.
7821
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00007822- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007846 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7847 for catch_warnings() also led to an improvement in the raising of a
7848 DeprecationWarning related to warnings.warn_explicit().
7849

7872
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00007873- Issue #2975: When compiling several extension modules with Visual Studio 2008
7874 from the same python interpreter, some environment variables would grow
7875 without limit.
7876
Benjamin Peterson37346b22008-08-23 20:27:43 +00007877- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
7878 exploitation of poor argument checking.
7879
Gerhard Häringef2276b2008-09-12 13:54:06 +00007880- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Gerhard Häring6e1afcf2008-09-12 18:58:57 +00007882- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
7883 remaining ones have "pysqlite_" prefix.
7884
Gerhard Häringe6872eb2008-09-12 22:33:22 +00007885- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

7893 wrapper for warnings.catch_warnings() that makes it easier to check
7894 that expected warning messages are being reported.
7895
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00007896- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007914What's New in Python 2.6 beta 3?
7915================================
7916
Barry Warsaw07a4a382008-08-21 01:15:08 +00007917*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007918
7919Core and Builtins
7920-----------------
7921
Guido van Rossumf8402962008-08-20 15:01:50 +00007922- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7923 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7924 extensions do not automatically benefit from the class attribute
7925 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7926 to their tp_flags field if they care. This is a backwards
7927 compatibility feature; in 3.0, all types will use the cache by
7928 default.
7929
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007930- Keyword arguments can now follow starred arguments. (``f(a, *args,
7931 keyword=23)`` is now valid syntax.)
7932
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007933- ctypes function pointers that are COM methods have a boolean True
7934 value again.
7935
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007936- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7937 by denying s# to parse objects that have a releasebuffer procedure,
7938 and introducing s*.
7939
Georg Brandl1e13ea92008-08-11 09:07:59 +00007940- Issue #3537: Fix an assertion failure when an empty but presized dict
7941 object was stored in the freelist.
7942
Mark Dickinsonb6467572008-08-04 21:30:09 +00007943- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7944 ValueError consistently across platforms.
7945
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007946- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7947 (64bit Unix, for example), unichr() would truncate its argument and return
7948 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7949
Neal Norwitze7d8be82008-07-31 17:17:14 +00007950- Apply security patches from Apple.
7951
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007952- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7953 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7954
Antoine Pitrou92f82162008-07-25 22:22:08 +00007955- Issue #1819: function calls with several named parameters are now on
7956 average 35% faster (as measured by pybench).
7957
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007958- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7959 the python debugger steps into a class statement: the free variables (local
7960 variables defined in an outer scope) would be deleted from the outer scope.
7961
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007962- Issue #2620: Overflow checking when allocating or reallocating memory
7963 was not always being done properly in some python types and extension
7964 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7965 all been updated to perform better checks and places in the code that
7966 would previously leak memory on the error path when such an allocation
7967 failed have been fixed.
7968

7970-------
7971
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007972- Issue #3612: Added some missing basic types in ctypes.wintypes.
7973
Benjamin Petersone977ad42008-08-20 01:42:01 +00007974- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7975 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7976
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007977- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7978 version reported by these tools does not necessarily follow the python
7979 version numbering scheme, so the module is less strict when parsing it.
7980
Nick Coghlanf70385a2008-08-18 12:42:46 +00007981- Issue #2235: Added Py3k warnings for types which will become unhashable
7982 under the stricter __hash__ inheritance rules in 3.0. Several types
7983 which did not meet the rules for hash invariants and were already
7984 unhashable in 3.0 have now been explicitly flagged as unhashable in
7985 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7986 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7987
Brett Cannon88f801d2008-08-18 00:46:22 +00007988- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7989 imported into the module but exposed as part of the module's API.
7990
Brett Cannon7b96f072008-08-18 00:41:11 +00007991- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7992
Brett Cannon46225e72008-08-18 00:36:52 +00007993- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007995- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7996
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007997- Issue #3575: Incremental decoder's decode function now takes bytearray
7998 by using 's*' instead of 't#'.
7999
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008000- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008001 fails unicode conversion on 2nd parameter. (windows only)
8002
Georg Brandl222e2082010-08-01 22:27:39 +00008003- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00008004 in a redirect.
8005
Brett Cannonabe423e2008-08-16 21:47:07 +00008006- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00008007 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00008008
Facundo Batistaeb90b782008-08-16 14:44:07 +00008009- Issue #2776: fixed small issue when handling an URL with double slash
8010 after a 302 response in the case of not going through a proxy.
8011
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008012- Issue #2676: in the email package, content-type parsing was hanging on
8013 pathological input because of quadratic or exponential behaviour of a
8014 regular expression.
8015
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008016- Issue #3476: binary buffered reading through the new "io" library is now
8017 thread-safe.
8018
Brett Cannonbf3157b2008-08-14 05:00:03 +00008019- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8020 since mimetools itself is deprecated. Because modules are cached, all
8021 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8022
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008023- Issue #3134: shutil referenced undefined WindowsError symbol.
8024
Robert Schuppenies14646332008-08-10 11:01:53 +00008025- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8026 menu entries were not deleted.
8027
Brett Cannon83e81842008-08-09 23:30:55 +00008028- Copied the implementation of reduce() to _functools.reduce() to have a
8029 version that did not raise a DeprecationWarning under -3.
8030
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008031- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8032 a MemoryError rather than silently stop the iteration.
8033
Guido van Rossum59ce9012008-08-09 14:55:34 +00008034- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8035 to _sre.compile() will now be rejected. This should not affect anybody
8036 since the re.compile() function never generates invalid re-bytecode.
8037
Skip Montanaroa032bf42008-08-08 22:52:51 +00008038- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8039 upon first access it can be automatically initialized from the csv file if
8040 it wasn't initialized during instantiation.
8041
Brett Cannon3aa2a492008-08-06 22:28:09 +00008042- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8043 the reload() built-in has been removed.
8044
Brett Cannon7e30b672008-08-04 21:52:25 +00008045- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008046 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00008047 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,

8049 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
8050 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
8051 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Antoine Pitroude781a42008-08-09 12:43:23 +00008057 asking for a specific length. This problem only affected files opened
8058 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00008059
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00008060- Issue #3449: Update decimal module to use most recent specification
8061 (v. 1.68) and tests (v. 2.58) from IBM.
8062
Georg Brandl222e2082010-08-01 22:27:39 +00008063- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

8067
Georg Brandlf9efabb2008-07-23 15:16:45 +00008068- Deprecate the "ast" parser function aliases.

8100 interaction with the tp_hash slot (added in 2.6b2) are now documented
8101
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008102- Issue #643841: The language reference now provides more detailed

8114-----------------
8115
Georg Brandl3e483f62008-07-16 22:57:41 +00008116- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8117 its methods now allow for items objects that can be converted to
8118 an integer using operator.index().
8119
Mark Dickinson64b7e502008-07-16 09:40:03 +00008120- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8121 produced a ValueError instead of giving the correct float.
8122
Eric Smitha5fa5a22008-07-16 00:11:49 +00008123- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8124 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8125
Mark Dickinson7103aa42008-07-15 19:08:33 +00008126- Issue #3008: the float type has a new instance method 'float.hex'
8127 and a new class method 'float.fromhex' to convert floating-point
8128 numbers to and from hexadecimal strings, respectively.
8129
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008130- Issue #2235: __hash__ is once again inherited by default. To allow
8131 collections.Hashable to remain meaningful in the presence of the
8132 default hash implementation (object.__hash__), it is now possible
8133 to explicit block inheritance of hash by setting __hash__=None at
8134 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8135 level.
8136
Nick Coghlanb028f502008-07-13 14:52:36 +00008137- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8138 the parent module cannot be found while performing an absolute import.
8139 This means that an incorrectly defined __package__ attribute will
8140 now only prevent relative imports in that module rather than causing
8141 all imports from that module to fail.
8142
Nick Coghlan14ff9942008-07-08 14:21:42 +00008143- Issue #2517: Allow unicode messages in Exceptions again by correctly

8152 threading.local: the first member set by a thread could be saved in
8153 another thread's dictionary.
8154
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008155- Issue #3004: Minor change to slice.indices(): the start and stop
8156 arguments are now treated identically, making the behaviour easier
8157 to describe and understand. For example, slice(None, -10,
8158 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8159 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8160 10, -1).
8161
Georg Brandl278fc502008-07-19 12:46:12 +00008162- Issue #3219: Calling a function with repeated keyword arguments,
8163 f(a=2, a=23), would not cause a syntax error. This was a regression
8164 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008165
Georg Brandl278fc502008-07-19 12:46:12 +00008166- Issue #2862: Make int and float freelist management consistent with
8167 other freelists. Changes their CompactFreeList apis into
8168 ClearFreeList apis and calls them via gc.collect().

8174 api functions without holding the GIL, which could lead to a fatal
8175 error when they failed.
8176
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008177- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008202- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8203 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008204 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008205 content-length. The problem had been corrected in the 2.4 branch, but never
8206 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008221- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00008673- Issue #1631171: Re-implement the 'warnings' module in C (the
8674 original Python code has been kept as backup). This will allow for
8675 using the 'warning's machinery in such places as the parser where
8676 use of pure Python code is not possible. Both the ``showarning()``
8677 and ``formatwarning()`` gain an optional 'line' argument which is
8678 not called by default for backwards-compatibility reasons. Setting
8679 ``warnings.showwarning()`` to an implementation that lacks support
8680 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008743- Issue #2550: The approach used by client/server code for obtaining
8744 ports to listen on in network-oriented tests has been refined in an
8745 effort to facilitate running multiple instances of the entire
8746 regression test suite in parallel without issue.
8747 test_support.bind_port() has been fixed such that it will always
8748 return a unique port -- which wasn't always the case with the
8749 previous implementation, especially if socket options had been set
8750 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8751 new implementation of bind_port() will actually raise an exception
8752 if it is passed an AF_INET/SOCK_STREAM socket with either the
8753 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8754 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8755 the socket it's been passed. This currently only applies to
8756 Windows. This option prevents any other sockets from binding to the
8757 host/port we've bound to, thus removing the possibility of the
8758 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8759 when a second SOCK_STREAM socket binds and accepts to a host/port
8760 that's already been bound by another socket. The optional preferred
8761 port parameter to bind_port() has been removed. Under no
8762 circumstances should tests be hard coding ports!
8763
8764 test_support.find_unused_port() has also been introduced, which will
8765 pass a temporary socket object to bind_port() in order to obtain an
8766 unused port. The temporary socket object is then closed and
8767 deleted, and the port is returned. This method should only be used
8768 for obtaining an unused port in order to pass to an external program
8769 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8770 a parameter to a server-oriented class that doesn't give you direct
8771 access to the underlying socket used.
8772
8773 Finally, test_support.HOST has been introduced, which should be used
8774 for the host argument of any relevant socket calls (i.e. bind and
8775 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008776
8777 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008778 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008779 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8780 test_asynchat and test_socket_ssl.
8781
Georg Brandl3ee81df2008-05-17 18:14:43 +00008782 It is now possible for multiple instances of the regression test
8783 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009062- Added the future_builtins module, which contains hex() and oct().
9063 These are the PEP 3127 version of these functions, designed to be
9064 compatible with the hex() and oct() builtins from Python 3.0. They
9065 differ slightly in their output formats from the existing, unchanged
9066 Python 2.6 builtins. The expected usage of the future_builtins
9067 module is:
9068 from future_builtins import hex, oct
9069
Eric Smith7ef40bf2008-02-20 23:34:22 +00009070- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9071 exponents for exponents with absolute value < 100. Follows C99
9072 standard. This is a change on Windows, which would use 3 digits.
9073 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9074 so that any alterations it does to the resulting string will be
9075 available in stringlib/formatter.h (for float.__format__).
9076
Eric Smith5a3c1352008-02-19 13:21:56 +00009077- Implemented PEP 3101, Advanced String Formatting. This adds a new
9078 builtin format(); a format() method for str and unicode; a
9079 __format__() method to object, str, unicode, int, long, float, and
9080 datetime; the class string.Formatter; and the C API
9081 PyObject_Format().
9082
Georg Brandl3ee81df2008-05-17 18:14:43 +00009083- Fixed several potential crashes, all caused by specially crafted
9084 __del__ methods exploiting objects in temporarily inconsistent
9085 state.

9096 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009097
Georg Brandl3ee81df2008-05-17 18:14:43 +00009098- Issue #2045: Fix an infinite recursion triggered when printing a

Georg Brandl3ee81df2008-05-17 18:14:43 +00009128- Patch #1473257: generator objects gain a gi_code attribute. This is
9129 the same object as the func_code attribute of the function that
9130 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009131
Georg Brandl3ee81df2008-05-17 18:14:43 +00009132- Issue #1920: "while 0" statements were completely removed by the
9133 compiler, even in the presence of an "else" clause, which is
9134 supposed to be run when the condition is false. Now the compiler
9135 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009136

Georg Brandl14404b62008-01-19 19:27:05 +00009152- Issue #1679: "0x" was taken as a valid integer literal.
9153
Georg Brandl6caad7d2008-01-26 14:19:22 +00009154- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009155 added.
9156
Christian Heimesc94e2b52008-01-14 04:13:37 +00009157- sys.float_info / PyFloat_GetInfo: The floating point information
9158 object was converted from a dict to a specialized structseq object.
9159
Georg Brandl3ee81df2008-05-17 18:14:43 +00009160- Patch #1816: Added sys.flags structseq. It exposes the status of
9161 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009162
Georg Brandl3ee81df2008-05-17 18:14:43 +00009163- Objects/structseq.c: Implemented new structseq representation. The
9164 patch makes structseqs (e.g. the return value of os.stat) more
9165 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009166
Georg Brandl3ee81df2008-05-17 18:14:43 +00009167- Patch #1700288: added a type attribute cache that caches method
9168 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009169
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009170- Bug #1776: __import__() no longer accepts filenames on any platform.
9171 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009172
Georg Brandlaed6c662008-01-07 17:25:53 +00009173- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9174
Georg Brandl3ee81df2008-05-17 18:14:43 +00009175- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9176 envvar and sys.dont_write_bytecode attribute. All these can be set
9177 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009178
Georg Brandl3ee81df2008-05-17 18:14:43 +00009179- Improve some exception messages when Windows fails to load an
9180 extension module. Now we get for example '%1 is not a valid Win32
9181 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009182
Georg Brandl3ee81df2008-05-17 18:14:43 +00009183- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009185- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9186 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009187
Christian Heimes0a8143f2007-12-18 23:22:54 +00009188- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009189 and INF. float("nan"), float("inf") and float("-inf") now work on
9190 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009191
Georg Brandl3ee81df2008-05-17 18:14:43 +00009192- Compiler now generates simpler and faster code for dictionary
9193 literals. The oparg for BUILD_MAP now indicates an estimated
9194 dictionary size. There is a new opcode, STORE_MAP, for adding
9195 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009205- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009206 SystemError.
9207
Nick Coghlanef01d822007-12-03 12:55:17 +00009208- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00009224- Patch #1739468: Directories and zipfiles containing a __main__.py
9225 file can now be directly executed by passing their name to the
9226 interpreter. The directory/zipfile is automatically inserted as the
9227 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009228
Georg Brandl3ee81df2008-05-17 18:14:43 +00009229- Issue #1265: Fix a problem with sys.settrace, if the tracing
9230 function uses a generator expression when at the same time the
9231 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009232
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009233- sets and frozensets now have an isdisjoint() method.
9234
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009235- optimize the performance of builtin.sum().
9236
Neal Norwitz44f326e2007-10-05 05:29:17 +00009237- Fix warnings found by the new version of the Coverity checker.
9238
Georg Brandl21e99f42010-03-07 15:23:59 +00009239- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009240 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9241 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009242
Georg Brandl3ee81df2008-05-17 18:14:43 +00009243- Issue #1686386: Tuple's tp_repr did not take into account the
9244 possibility of having a self-referential tuple, which is possible
9245 from C code. Nor did object's tp_str consider that a type's tp_str
9246 could do something that could lead to an inifinite recursion.
9247 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9248 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009249
Georg Brandl3ee81df2008-05-17 18:14:43 +00009250- Issue #1164: It was possible to trigger deadlock when using the
9251 'print' statement to write to a file since the GIL was not released
9252 as needed. Now PyObject_Print() does the right thing along with
9253 various tp_print implementations of the built-in types and those in
9254 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009255
Georg Brandl3ee81df2008-05-17 18:14:43 +00009256- Issue #1147: Exceptions were directly allowing string exceptions in
9257 their throw() method even though string exceptions no longer
9258 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009259
Georg Brandl3ee81df2008-05-17 18:14:43 +00009260- Issue #1096: Prevent a segfault from getting the repr of a very
9261 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009262
Brett Cannon1e534b52007-09-07 04:18:30 +00009263- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009264 PyObject_Call() never calling back out to Python code to trigger
9265 recursion depth updates/checks. Required the creation of a static
9266 RuntimeError instance in case normalizing an exception put the
9267 recursion check value past its limit. Fixes crashers
9268 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009269
Georg Brandl3ee81df2008-05-17 18:14:43 +00009270- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00009283- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009284 __*__ attributes. (Some already existed, e.g., __doc__ and
9285 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009286
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009287- Add -3 option to the interpreter to warn about features that are
9288 deprecated and will be changed/removed in Python 3.0.
9289
Georg Brandl2134e752007-05-21 20:34:16 +00009290- Patch #1686487: you can now pass any mapping after '**' in function
9291 calls.
9292
Collin Winter62903052007-05-18 23:11:24 +00009293- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009294 "except E as target:". This is to provide forwards compatibility
9295 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009296
Brett Cannon229cee22007-05-05 01:34:02 +00009297- Deprecate BaseException.message as per PEP 352.
9298
Georg Brandl3ee81df2008-05-17 18:14:43 +00009299- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009300 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009301
Vinay Sajip8549ce32007-05-06 17:53:37 +00009302- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009303 setting a plain string, ie don't expand to single letter identifiers.
9304
Raymond Hettinger13936692007-04-11 18:40:58 +00009305- Request #1191699: Slices can now be pickled.
9306
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009307- Request #1193128: str.translate() now allows a None argument for
9308 translations that only remove characters without re-mapping the
9309 remaining characters.
9310
Georg Brandl5cb76c12007-03-21 09:00:39 +00009311- Patch #1682205: a TypeError while unpacking an iterable is no longer
9312 masked by a generic one with the message "unpack non-sequence".
9313
Neal Norwitzaa754b72007-03-21 06:39:48 +00009314- Remove unused file Python/fmod.c.
9315
Guido van Rossum143b5642007-03-23 04:58:42 +00009316- Bug #1683368: The object.__init__() and object.__new__() methods are
9317 now stricter in rejecting excess arguments. The only time when
9318 either allows excess arguments is when it is not overridden and the
9319 other one is. For backwards compatibility, when both are
9320 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009321 warning later). Also, type.__init__() insists on the same signature
9322 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009323
Georg Brandl3ee81df2008-05-17 18:14:43 +00009324- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9325 object to complex using its __complex__() method before falling back
9326 to the __float__() method. Therefore, the functions in the cmath
9327 module now can operate on objects that define a __complex__()
9328 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009329
Georg Brandl3ee81df2008-05-17 18:14:43 +00009330- Patch #1623563: allow __class__ assignment for classes with
9331 __slots__. The old and the new class are still required to have the
9332 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00009333
Georg Brandl3ee81df2008-05-17 18:14:43 +00009334- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00009337- Patch #1462488: Python no longer segfaults when
9338 ``object.__reduce_ex__()`` is called with an object that is faking
9339 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009340
Georg Brandl3ee81df2008-05-17 18:14:43 +00009341- Patch #1680015: Don't modify __slots__ tuple if it contains an

9345
Georg Brandl7b9c5552007-03-12 14:30:05 +00009346- Bug #1678647: write a newline after printing an exception in any
9347 case, even when converting the value to a string failed.
9348
Georg Brandl871f1bc2007-03-12 13:17:36 +00009349- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009350 its argument, if it exists. If not, it will work like before. This
9351 allows customizing the output of dir() in the presence of a
9352 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009353
Collin Winter276887b2007-03-12 16:11:39 +00009354- Patch #922167: Python no longer segfaults when faced with infinitely
9355 self-recursive reload() calls (as reported by bug #742342).
9356
Georg Brandl3ee81df2008-05-17 18:14:43 +00009357- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00009360- Patch #1491866: change the complex() constructor to allow
9361 parthensized forms. This means complex(repr(x)) now works instead of
9362 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009363
Georg Brandlaa2321b2007-03-07 00:40:28 +00009364- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009365 makes the filenames the warning module prints much more sensible
9366 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009367
Georg Brandl49aafc92007-03-07 00:34:46 +00009368- Variant of patch #697613: don't exit the interpreter on a SystemExit
9369 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00009370 variable is given, but break into the interactive interpreter just
9371 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00009378
Georg Brandl0fca97a2007-03-05 22:28:08 +00009379- Patch #1674228: when assigning a slice (old-style), check for the
9380 sq_ass_slice instead of the sq_slice slot.
9381
Georg Brandl3ee81df2008-05-17 18:14:43 +00009382- When printing an unraisable error, don't print exceptions. before
9383 the name. This duplicates the behavior whening normally printing
9384 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00009385
Georg Brandl3ee81df2008-05-17 18:14:43 +00009386- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00009885- Added a timeout parameter to the constructor of other protocols
9886 (telnetlib, ftplib, smtplib and poplib). This is second part of the
9887 work started with create_connection() and timeout in httplib, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00009916 AttributeError instead of an IOError when the server's response

9949
Georg Brandl92a6bae2007-03-13 17:43:32 +00009950- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009951 are set for invalid interpolation sequences that would lead to
9952 errors on reading back those values.

10008 TestCase and TestSuite subclasses (not instances) are no longer
10009 accepted in TestSuite.addTest(). This should cause no

10011 -- the failure just occurred later, with a more cumbersome
10012 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010395 time so that opening a database previously created with the DB_DUP
10396 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10397 opens. Specifically: dictionary assignment to a DB object will
10398 replace all values for a given key when the database allows
10399 duplicate values. DB users should use DB.put(k, v) when they want
10400 to store duplicates; not DB[k] = v.

10407 characters with ASCII value less than 32. Also, it correctly quotes
10408 dots only if they occur on a single line, as opposed to the previous
10409 behavior of quoting dots if they are the second character of any
10410 line.
