480
481- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
482 and later systems as is currently done for Python 3.x installers.
483 For 2.7.7 only, we will provide three installers:
484 the legacy deprecated 10.3+ 32-bit-only format;
485 the newer 10.5+ 32-bit-only format;
486 and the unchanged 10.6+ 64-/32-bit format.
487 Although binary installers will no longer be available from
488 python.org as of 2.7.8, it will still be possible to build from
489 source on 10.3.9 and 10.4 systems if necessary.

1868 In particular, fix extension module build failures when trying to use
1869 32-bit-only installer Pythons on systems with Xcode 4 (currently
1870 OS X 10.8, 10.7, and optionally 10.6).
1871 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1872 * Since Xcode 4 removes ppc support, extension module builds now
1873 check for ppc compiler support and by default remove ppc and
1874 ppc64 archs when they are not available.
1875 * Extension module builds now revert to using system installed
1876 headers and libs (/usr and /System/Library) if the SDK used
1877 to build the interpreter is not installed or has moved.
1878 * Try to avoid building extension modules with deprecated
1879 and problematic Apple llvm-gcc compiler. If original compiler
1880 is not available, use clang instead by default.

Ned Deily0d0ea482012-02-10 12:59:06 +01002311- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2312 Distutils-based packages with C extension modules may fail because
2313 Apple has removed gcc-4.2, the version used to build python.org
2314 64-bit/32-bit Pythons. If the user does not explicitly override
2315 the default C compiler by setting the CC environment variable,
2316 Distutils will now attempt to compile extension modules with clang
2317 if gcc-4.2 is required but not found. Also as a convenience, if
2318 the user does explicitly set CC, substitute its value as the default
2319 compiler in the Distutils LDSHARED configuration variable for OS X.
2320 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2321 SDK, neither of which are available in Xcode 4. This change does not

Ned Deily87e82bb2011-06-28 19:52:59 -07002572- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2573 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2574 interpreter process. This could cause failures in non-Distutils subprocesses
2575 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002576 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002577 deployment target only in the environment of each build subprocess. It is
2578 still possible to globally override the default by setting
2579 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2580 greater or equal to the default value, the value with which the interpreter
2581 was built.

2610 updating the check interval, so if the user decreases the check interval,
2611 the ticker doesn't have to wind down to zero from the old starting point
2612 before the new interval takes effect. And if the user increases the
2613 interval, it makes sure the new limit takes effect right away rather have an
2614 early task switch before recognizing the new interval.

3584 by Andrew Bennetts.

3593
Raymond Hettinger20397532010-09-12 02:11:45 +00003594- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3595 This prevents user-created self-referencing ordered dictionaries from
3596 becoming permanently uncollectable GC garbage. The downside is that
3597 removing __del__ means that the internal doubly-linked list has to wait for
3598 GC collection rather than freeing memory immediately when the refcnt drops
3599 to zero.
3600
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003601- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3604
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003605- Issue #9792: In case of connection failure, socket.create_connection()
3606 would swallow the exception and raise a new one, making it impossible
3607 to fetch the original errno, or to filter timeout errors. Now the
3608 original error is re-raised.
3609
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003610- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3611 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3612 be updated back after the system call. Original patch by Brian Brazil.

3619
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003620- Issue #808164: Fixed socket.close to avoid references to globals, to

3625 heuristic. Patch by Terry Reedy and Eli Bendersky
3626
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003627- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3628 falling into recursion.
3629
R. David Murray7c4bf552010-08-25 01:45:57 +00003630- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3631 character years even if the message contains RFC822 two character years.
3632
Daniel Stutzbach91287322010-08-24 21:09:30 +00003633- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00003644- Issue #9214: Set operations on KeysView or ItemsView in the collections
3645 module now correctly return a set. (Patch by Eli Bendersky.)
3646
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003647- Issue #9617: Signals received during a low-level write operation aren't
3648 ignored by the buffered IO layer anymore.
3649
Benjamin Peterson52c36052010-08-21 03:03:22 +00003650- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3651 are not held onto after they are deleted elsewhere.
3652
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003653- Issue #9626: the view methods for collections.OrderedDict() were returning
3654 the unordered versions inherited from dict. Those methods are now
3655 overridden to provide ordered views.
3656
Éric Araujo0389ae62010-08-14 03:07:46 +00003657- Issue #8688: MANIFEST files created by distutils now include a magic
3658 comment indicating they are generated. Manually maintained MANIFESTs
3659 without this marker will not be overwritten or removed.
3660
Antoine Pitroue1436d12010-08-12 15:25:51 +00003661- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3662 and a BadZipfile error is raised if it doesn't match (as used to be the
3663 case in Python 2.5 and earlier).
3664
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003665- Issue #9550: a BufferedReader could issue an additional read when the
3666 original read request had been satisfied, which could block indefinitely
3667 when the underlying raw IO channel was e.g. a socket. Report and original
3668 patch by Jason V. Miller.
3669
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003670- Issue #9551: Don't raise TypeError when setting the value to None for

3699 does not contain a '-', instead of raising an error.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004071- Issue #8748: Fix two issues with comparisons between complex and integer
4072 objects. (1) The comparison could incorrectly return True in some cases
4073 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4074 (2) The comparison raised an OverflowError for large integers, leading
4075 to unpredictable exceptions when combining integers and complex objects
4076 in sets or dicts.

Georg Brandlfee0f442010-05-22 21:26:21 +00004317- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
4318 the method could block indefinitely if called just before the event loop
4319 started running. This also fixes the occasional freezes witnessed in
4320 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +00004322- Issue #5103: SSL handshake would ignore the socket timeout and block
4323 indefinitely if the other end didn't respond.
4324
Georg Brandlfee0f442010-05-22 21:26:21 +00004325- The do_handshake() method of SSL objects now adjusts the blocking mode of the
4326 SSL structure if necessary (as other methods already do).

Georg Brandlfee0f442010-05-22 21:26:21 +00004458- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4459 with a non-empty format string. This is an effort to future-proof user
4460 code. If a derived class does not currently implement __format__ but later
4461 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004462 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004463 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004496- Issue #8257: The Decimal construct now accepts a float instance directly,
4497 converting that float to a Decimal of equal value:

Georg Brandlfee0f442010-05-22 21:26:21 +00004513- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4514 InvalidOperation instead of returning False. (Comparisons involving a quiet
4515 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4516 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004517
Georg Brandlfee0f442010-05-22 21:26:21 +00004518- Issue #2531: Comparison operations between floats and Decimal instances now
4519 return a result based on the numeric values of the operands; previously they
4520 returned an arbitrary result based on the relative ordering of id(float) and
4521 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00004535- Comparisons using one of <, <=, >, >= between a complex instance and a
4536 Fractions instance now raise TypeError instead of returning True/False. This
4537 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4538 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004956 file position when calling `truncate()`. It would previously change the file
4957 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004958 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4961 class used to represent files stored inside an archive. The new
4962 implementation is significantly faster and can be wrapped in a
4963 ``io.BufferedReader`` object for more speedups. It also solves an issue
4964 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5053-----------------
5054
Georg Brandlba83f822010-03-14 09:50:54 +00005055- The ``__complex__()`` method is now looked up on the class of instances to
5056 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005057
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005058- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5059 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5060
Mark Dickinson1b34d252010-01-01 17:27:30 +00005061- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005062 DeprecationWarning when passed a float argument where an integer was expected.
5063 These functions and methods now raise TypeError instead. The majority of the
5064 effects of this change are in the extension modules, but some core functions
5065 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5066 and many unicode/str methods.

5077 used to drop the time part of the result.
5078
Georg Brandlba83f822010-03-14 09:50:54 +00005079- Issue #1811: Improve accuracy and cross-platform consistency for true division
5080 of integers: the result of a/b is now correctly rounded for ints a and b (at
5081 least on IEEE 754 platforms), and in particular does not depend on the
5082 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00005083
Georg Brandlba83f822010-03-14 09:50:54 +00005084- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00005089 executables on OSX.
5090
Georg Brandlba83f822010-03-14 09:50:54 +00005091 These executables now work properly with the arch(1) command: ``arch -ppc
5092 python`` will start a universal binary version of python in PPC mode (unlike
5093 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00005094

Georg Brandlba83f822010-03-14 09:50:54 +00005115 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00005255- Issue #7117: On almost all platforms: float-to-string and string-to-float
5256 conversions within Python are now correctly rounded. Places these conversions
5257 occur include: str for floats and complex numbers; the float and complex
5258 constructors; old-style and new-style numeric formatting; serialization and
5259 deserialization of floats and complex numbers using marshal, pickle and json;
5260 parsing of float and imaginary literals in Python code; Decimal-to-float
5261 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005262
Georg Brandlba83f822010-03-14 09:50:54 +00005263 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5264 providing correctly-rounded strtod and dtoa C functions. This code is
5265 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5266 the C compiler. There may be a small number of platforms on which correct
5267 operation of this code cannot be guaranteed, so the code is not used: notably,
5268 this applies to platforms where the C double format is not IEEE 754 binary64,
5269 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5270 and Python's configure script is unable to determine how to change the FPU
5271 precision. On these platforms conversions use the platform strtod and dtoa,
5272 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005274- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5275 uses the correctly-rounded string <-> float conversions described above (when
5276 available), and so produces correctly rounded results that will display nicely
5277 under the float repr. There are two related small changes: (1) round now
5278 accepts any class with an ``__index__()`` method for its second argument (but
5279 no longer accepts floats for the second argument), and (2) an excessively
5280 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5281 raises an exception.

6866 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6867 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6868 neither __int__ nor __long__, TypeError used to be raised (with a
6869 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6870 struct.error in other cases.

6873 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007067- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

7069 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7070 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00007168 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7169 for catch_warnings() also led to an improvement in the raising of a
7170 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007236What's New in Python 2.6 beta 3?
7237================================
7238
Barry Warsaw07a4a382008-08-21 01:15:08 +00007239*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007240
7241Core and Builtins
7242-----------------
7243
Guido van Rossumf8402962008-08-20 15:01:50 +00007244- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7245 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7246 extensions do not automatically benefit from the class attribute
7247 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7248 to their tp_flags field if they care. This is a backwards
7249 compatibility feature; in 3.0, all types will use the cache by
7250 default.
7251
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007252- Keyword arguments can now follow starred arguments. (``f(a, *args,
7253 keyword=23)`` is now valid syntax.)
7254
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007255- ctypes function pointers that are COM methods have a boolean True
7256 value again.
7257
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007258- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7259 by denying s# to parse objects that have a releasebuffer procedure,
7260 and introducing s*.
7261
Georg Brandl1e13ea92008-08-11 09:07:59 +00007262- Issue #3537: Fix an assertion failure when an empty but presized dict
7263 object was stored in the freelist.
7264
Mark Dickinsonb6467572008-08-04 21:30:09 +00007265- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7266 ValueError consistently across platforms.
7267
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007268- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7269 (64bit Unix, for example), unichr() would truncate its argument and return
7270 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7271
Neal Norwitze7d8be82008-07-31 17:17:14 +00007272- Apply security patches from Apple.
7273
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007274- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7275 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7276
Antoine Pitrou92f82162008-07-25 22:22:08 +00007277- Issue #1819: function calls with several named parameters are now on
7278 average 35% faster (as measured by pybench).
7279
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007280- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7281 the python debugger steps into a class statement: the free variables (local
7282 variables defined in an outer scope) would be deleted from the outer scope.
7283
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007284- Issue #2620: Overflow checking when allocating or reallocating memory
7285 was not always being done properly in some python types and extension
7286 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7287 all been updated to perform better checks and places in the code that
7288 would previously leak memory on the error path when such an allocation
7289 failed have been fixed.

7292-------
7293
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007294- Issue #3612: Added some missing basic types in ctypes.wintypes.
7295
Benjamin Petersone977ad42008-08-20 01:42:01 +00007296- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7297 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7298
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007299- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7300 version reported by these tools does not necessarily follow the python
7301 version numbering scheme, so the module is less strict when parsing it.
7302
Nick Coghlanf70385a2008-08-18 12:42:46 +00007303- Issue #2235: Added Py3k warnings for types which will become unhashable
7304 under the stricter __hash__ inheritance rules in 3.0. Several types
7305 which did not meet the rules for hash invariants and were already
7306 unhashable in 3.0 have now been explicitly flagged as unhashable in
7307 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7308 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7309
Brett Cannon88f801d2008-08-18 00:46:22 +00007310- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7311 imported into the module but exposed as part of the module's API.
7312
Brett Cannon7b96f072008-08-18 00:41:11 +00007313- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7314
Brett Cannon46225e72008-08-18 00:36:52 +00007315- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007317- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7318
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007319- Issue #3575: Incremental decoder's decode function now takes bytearray
7320 by using 's*' instead of 't#'.
7321
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007322- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007323 fails unicode conversion on 2nd parameter. (windows only)
7324
Georg Brandl222e2082010-08-01 22:27:39 +00007325- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007326 in a redirect.
7327
Brett Cannonabe423e2008-08-16 21:47:07 +00007328- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007329 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007330
Facundo Batistaeb90b782008-08-16 14:44:07 +00007331- Issue #2776: fixed small issue when handling an URL with double slash
7332 after a 302 response in the case of not going through a proxy.
7333
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007334- Issue #2676: in the email package, content-type parsing was hanging on
7335 pathological input because of quadratic or exponential behaviour of a
7336 regular expression.
7337
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007338- Issue #3476: binary buffered reading through the new "io" library is now
7339 thread-safe.
7340
Brett Cannonbf3157b2008-08-14 05:00:03 +00007341- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7342 since mimetools itself is deprecated. Because modules are cached, all
7343 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7344
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007345- Issue #3134: shutil referenced undefined WindowsError symbol.
7346
Robert Schuppenies14646332008-08-10 11:01:53 +00007347- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7348 menu entries were not deleted.
7349
Brett Cannon83e81842008-08-09 23:30:55 +00007350- Copied the implementation of reduce() to _functools.reduce() to have a
7351 version that did not raise a DeprecationWarning under -3.
7352
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007353- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7354 a MemoryError rather than silently stop the iteration.
7355
Guido van Rossum59ce9012008-08-09 14:55:34 +00007356- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7357 to _sre.compile() will now be rejected. This should not affect anybody
7358 since the re.compile() function never generates invalid re-bytecode.
7359
Skip Montanaroa032bf42008-08-08 22:52:51 +00007360- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7361 upon first access it can be automatically initialized from the csv file if
7362 it wasn't initialized during instantiation.
7363
Brett Cannon3aa2a492008-08-06 22:28:09 +00007364- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7365 the reload() built-in has been removed.
7366
Brett Cannon7e30b672008-08-04 21:52:25 +00007367- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007368 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007379 asking for a specific length. This problem only affected files opened
7380 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007381
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007382- Issue #3449: Update decimal module to use most recent specification
7383 (v. 1.68) and tests (v. 2.58) from IBM.

7436-----------------
7437
Georg Brandl3e483f62008-07-16 22:57:41 +00007438- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7439 its methods now allow for items objects that can be converted to
7440 an integer using operator.index().
7441
Mark Dickinson64b7e502008-07-16 09:40:03 +00007442- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7443 produced a ValueError instead of giving the correct float.
7444
Eric Smitha5fa5a22008-07-16 00:11:49 +00007445- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7446 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7447
Mark Dickinson7103aa42008-07-15 19:08:33 +00007448- Issue #3008: the float type has a new instance method 'float.hex'
7449 and a new class method 'float.fromhex' to convert floating-point
7450 numbers to and from hexadecimal strings, respectively.
7451
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007452- Issue #2235: __hash__ is once again inherited by default. To allow
7453 collections.Hashable to remain meaningful in the presence of the
7454 default hash implementation (object.__hash__), it is now possible
7455 to explicit block inheritance of hash by setting __hash__=None at
7456 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7457 level.
7458
Nick Coghlanb028f502008-07-13 14:52:36 +00007459- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7460 the parent module cannot be found while performing an absolute import.
7461 This means that an incorrectly defined __package__ attribute will
7462 now only prevent relative imports in that module rather than causing
7463 all imports from that module to fail.
7464
Nick Coghlan14ff9942008-07-08 14:21:42 +00007465- Issue #2517: Allow unicode messages in Exceptions again by correctly

7475 another thread's dictionary.
7476
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007477- Issue #3004: Minor change to slice.indices(): the start and stop
7478 arguments are now treated identically, making the behaviour easier
7479 to describe and understand. For example, slice(None, -10,
7480 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7481 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7482 10, -1).
7483
Georg Brandl278fc502008-07-19 12:46:12 +00007484- Issue #3219: Calling a function with repeated keyword arguments,
7485 f(a=2, a=23), would not cause a syntax error. This was a regression
7486 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007487
Georg Brandl278fc502008-07-19 12:46:12 +00007488- Issue #2862: Make int and float freelist management consistent with
7489 other freelists. Changes their CompactFreeList apis into

7496 api functions without holding the GIL, which could lead to a fatal
7497 error when they failed.
7498
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007499- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007524- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7525 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007526 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007527 content-length. The problem had been corrected in the 2.4 branch, but never
7528 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007543- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007995- Issue #1631171: Re-implement the 'warnings' module in C (the
7996 original Python code has been kept as backup). This will allow for
7997 using the 'warning's machinery in such places as the parser where
7998 use of pure Python code is not possible. Both the ``showarning()``
7999 and ``formatwarning()`` gain an optional 'line' argument which is
8000 not called by default for backwards-compatibility reasons. Setting
8001 ``warnings.showwarning()`` to an implementation that lacks support
8002 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008065- Issue #2550: The approach used by client/server code for obtaining
8066 ports to listen on in network-oriented tests has been refined in an
8067 effort to facilitate running multiple instances of the entire
8068 regression test suite in parallel without issue.
8069 test_support.bind_port() has been fixed such that it will always
8070 return a unique port -- which wasn't always the case with the
8071 previous implementation, especially if socket options had been set
8072 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8073 new implementation of bind_port() will actually raise an exception
8074 if it is passed an AF_INET/SOCK_STREAM socket with either the
8075 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8076 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8077 the socket it's been passed. This currently only applies to
8078 Windows. This option prevents any other sockets from binding to the
8079 host/port we've bound to, thus removing the possibility of the
8080 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8081 when a second SOCK_STREAM socket binds and accepts to a host/port
8082 that's already been bound by another socket. The optional preferred
8083 port parameter to bind_port() has been removed. Under no
8084 circumstances should tests be hard coding ports!
8085
8086 test_support.find_unused_port() has also been introduced, which will
8087 pass a temporary socket object to bind_port() in order to obtain an
8088 unused port. The temporary socket object is then closed and
8089 deleted, and the port is returned. This method should only be used
8090 for obtaining an unused port in order to pass to an external program
8091 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8092 a parameter to a server-oriented class that doesn't give you direct
8093 access to the underlying socket used.
8094
8095 Finally, test_support.HOST has been introduced, which should be used
8096 for the host argument of any relevant socket calls (i.e. bind and
8097 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008098
8099 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008100 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008101 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8102 test_asynchat and test_socket_ssl.
8103
Georg Brandl3ee81df2008-05-17 18:14:43 +00008104 It is now possible for multiple instances of the regression test
8105 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008384- Added the future_builtins module, which contains hex() and oct().
8385 These are the PEP 3127 version of these functions, designed to be
8386 compatible with the hex() and oct() builtins from Python 3.0. They
8387 differ slightly in their output formats from the existing, unchanged
8388 Python 2.6 builtins. The expected usage of the future_builtins
8389 module is:
8390 from future_builtins import hex, oct
8391
Eric Smith7ef40bf2008-02-20 23:34:22 +00008392- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8393 exponents for exponents with absolute value < 100. Follows C99
8394 standard. This is a change on Windows, which would use 3 digits.
8395 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8396 so that any alterations it does to the resulting string will be
8397 available in stringlib/formatter.h (for float.__format__).
8398
Eric Smith5a3c1352008-02-19 13:21:56 +00008399- Implemented PEP 3101, Advanced String Formatting. This adds a new
8400 builtin format(); a format() method for str and unicode; a
8401 __format__() method to object, str, unicode, int, long, float, and
8402 datetime; the class string.Formatter; and the C API
8403 PyObject_Format().
8404
Georg Brandl3ee81df2008-05-17 18:14:43 +00008405- Fixed several potential crashes, all caused by specially crafted
8406 __del__ methods exploiting objects in temporarily inconsistent
8407 state.

8418 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008419
Georg Brandl3ee81df2008-05-17 18:14:43 +00008420- Issue #2045: Fix an infinite recursion triggered when printing a
8421 subclass of collections.defaultdict, if its default_factory is set
8422 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008423
Christian Heimesf75dbef2008-02-08 00:11:31 +00008424- Fixed a minor memory leak in dictobject.c. The content of the free

8431 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008432 to compact the internal free lists of pre-allocted ints and floats.
8433
Georg Brandl3ee81df2008-05-17 18:14:43 +00008434- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8435 calls. Python expected the return type int but the fork familie
8436 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008450- Patch #1473257: generator objects gain a gi_code attribute. This is
8451 the same object as the func_code attribute of the function that
8452 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008453
Georg Brandl3ee81df2008-05-17 18:14:43 +00008454- Issue #1920: "while 0" statements were completely removed by the
8455 compiler, even in the presence of an "else" clause, which is
8456 supposed to be run when the condition is false. Now the compiler
8457 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008458

8475
Georg Brandl6caad7d2008-01-26 14:19:22 +00008476- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008477 added.
8478
Christian Heimesc94e2b52008-01-14 04:13:37 +00008479- sys.float_info / PyFloat_GetInfo: The floating point information
8480 object was converted from a dict to a specialized structseq object.
8481
Georg Brandl3ee81df2008-05-17 18:14:43 +00008482- Patch #1816: Added sys.flags structseq. It exposes the status of
8483 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008484
Georg Brandl3ee81df2008-05-17 18:14:43 +00008485- Objects/structseq.c: Implemented new structseq representation. The
8486 patch makes structseqs (e.g. the return value of os.stat) more
8487 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008488
Georg Brandl3ee81df2008-05-17 18:14:43 +00008489- Patch #1700288: added a type attribute cache that caches method
8490 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008491
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008492- Bug #1776: __import__() no longer accepts filenames on any platform.
8493 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008494
Georg Brandlaed6c662008-01-07 17:25:53 +00008495- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8496
Georg Brandl3ee81df2008-05-17 18:14:43 +00008497- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8498 envvar and sys.dont_write_bytecode attribute. All these can be set
8499 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008500
Georg Brandl3ee81df2008-05-17 18:14:43 +00008501- Improve some exception messages when Windows fails to load an
8502 extension module. Now we get for example '%1 is not a valid Win32
8503 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008504

8508 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008509
Christian Heimes0a8143f2007-12-18 23:22:54 +00008510- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008511 and INF. float("nan"), float("inf") and float("-inf") now work on
8512 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008513
Georg Brandl3ee81df2008-05-17 18:14:43 +00008514- Compiler now generates simpler and faster code for dictionary
8515 literals. The oparg for BUILD_MAP now indicates an estimated
8516 dictionary size. There is a new opcode, STORE_MAP, for adding
8517 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008546- Patch #1739468: Directories and zipfiles containing a __main__.py
8547 file can now be directly executed by passing their name to the
8548 interpreter. The directory/zipfile is automatically inserted as the
8549 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008550
Georg Brandl3ee81df2008-05-17 18:14:43 +00008551- Issue #1265: Fix a problem with sys.settrace, if the tracing
8552 function uses a generator expression when at the same time the
8553 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008554
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008555- sets and frozensets now have an isdisjoint() method.
8556
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008557- optimize the performance of builtin.sum().
8558

8560
Georg Brandl21e99f42010-03-07 15:23:59 +00008561- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008562 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8563 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008564
Georg Brandl3ee81df2008-05-17 18:14:43 +00008565- Issue #1686386: Tuple's tp_repr did not take into account the
8566 possibility of having a self-referential tuple, which is possible
8567 from C code. Nor did object's tp_str consider that a type's tp_str
8568 could do something that could lead to an inifinite recursion.
8569 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8570 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008571
Georg Brandl3ee81df2008-05-17 18:14:43 +00008572- Issue #1164: It was possible to trigger deadlock when using the
8573 'print' statement to write to a file since the GIL was not released
8574 as needed. Now PyObject_Print() does the right thing along with
8575 various tp_print implementations of the built-in types and those in
8576 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008577
Georg Brandl3ee81df2008-05-17 18:14:43 +00008578- Issue #1147: Exceptions were directly allowing string exceptions in
8579 their throw() method even though string exceptions no longer
8580 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008581
Georg Brandl3ee81df2008-05-17 18:14:43 +00008582- Issue #1096: Prevent a segfault from getting the repr of a very
8583 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008584
Brett Cannon1e534b52007-09-07 04:18:30 +00008585- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008586 PyObject_Call() never calling back out to Python code to trigger
8587 recursion depth updates/checks. Required the creation of a static
8588 RuntimeError instance in case normalizing an exception put the
8589 recursion check value past its limit. Fixes crashers
8590 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008591
Georg Brandl3ee81df2008-05-17 18:14:43 +00008592- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008605- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008606 __*__ attributes. (Some already existed, e.g., __doc__ and
8607 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008608
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008609- Add -3 option to the interpreter to warn about features that are
8610 deprecated and will be changed/removed in Python 3.0.
8611
Georg Brandl2134e752007-05-21 20:34:16 +00008612- Patch #1686487: you can now pass any mapping after '**' in function
8613 calls.
8614
Collin Winter62903052007-05-18 23:11:24 +00008615- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008616 "except E as target:". This is to provide forwards compatibility
8617 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008618
Brett Cannon229cee22007-05-05 01:34:02 +00008619- Deprecate BaseException.message as per PEP 352.
8620
Georg Brandl3ee81df2008-05-17 18:14:43 +00008621- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008622 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008623
Vinay Sajip8549ce32007-05-06 17:53:37 +00008624- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008625 setting a plain string, ie don't expand to single letter identifiers.
8626
Raymond Hettinger13936692007-04-11 18:40:58 +00008627- Request #1191699: Slices can now be pickled.
8628
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008629- Request #1193128: str.translate() now allows a None argument for
8630 translations that only remove characters without re-mapping the
8631 remaining characters.
8632
Georg Brandl5cb76c12007-03-21 09:00:39 +00008633- Patch #1682205: a TypeError while unpacking an iterable is no longer
8634 masked by a generic one with the message "unpack non-sequence".
8635
Neal Norwitzaa754b72007-03-21 06:39:48 +00008636- Remove unused file Python/fmod.c.
8637
Guido van Rossum143b5642007-03-23 04:58:42 +00008638- Bug #1683368: The object.__init__() and object.__new__() methods are
8639 now stricter in rejecting excess arguments. The only time when
8640 either allows excess arguments is when it is not overridden and the
8641 other one is. For backwards compatibility, when both are
8642 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008643 warning later). Also, type.__init__() insists on the same signature
8644 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008645
Georg Brandl3ee81df2008-05-17 18:14:43 +00008646- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8647 object to complex using its __complex__() method before falling back
8648 to the __float__() method. Therefore, the functions in the cmath
8649 module now can operate on objects that define a __complex__()
8650 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008651
Georg Brandl3ee81df2008-05-17 18:14:43 +00008652- Patch #1623563: allow __class__ assignment for classes with
8653 __slots__. The old and the new class are still required to have the
8654 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008655

8660 ``object.__reduce_ex__()`` is called with an object that is faking
8661 its type.

8667
Georg Brandl7b9c5552007-03-12 14:30:05 +00008668- Bug #1678647: write a newline after printing an exception in any
8669 case, even when converting the value to a string failed.
8670
Georg Brandl871f1bc2007-03-12 13:17:36 +00008671- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008672 its argument, if it exists. If not, it will work like before. This
8673 allows customizing the output of dir() in the presence of a
8674 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008682- Patch #1491866: change the complex() constructor to allow
8683 parthensized forms. This means complex(repr(x)) now works instead of
8684 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008685
Georg Brandlaa2321b2007-03-07 00:40:28 +00008686- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008687 makes the filenames the warning module prints much more sensible
8688 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008689

8691 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008692 variable is given, but break into the interactive interpreter just
8693 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008701- Patch #1674228: when assigning a slice (old-style), check for the
8702 sq_ass_slice instead of the sq_slice slot.
8703
Georg Brandl3ee81df2008-05-17 18:14:43 +00008704- When printing an unraisable error, don't print exceptions. before
8705 the name. This duplicates the behavior whening normally printing
8706 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00009207- Added a timeout parameter to the constructor of other protocols
9208 (telnetlib, ftplib, smtplib and poplib). This is second part of the
9209 work started with create_connection() and timeout in httplib, and
9210 closes patch #723312.
9211
Vinay Sajip8549ce32007-05-06 17:53:37 +00009212- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00009238 AttributeError instead of an IOError when the server's response
9239 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00009240

Georg Brandl3ee81df2008-05-17 18:14:43 +00009245- Patch #1429539: pdb now correctly initializes the __main__ module
9246 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00009247 correctly now.
9248

Georg Brandl3ee81df2008-05-17 18:14:43 +00009256- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00009269- Patch #1581073: add a flag to textwrap that prevents the dropping of

9271
Georg Brandl92a6bae2007-03-13 17:43:32 +00009272- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009273 are set for invalid interpolation sequences that would lead to
9274 errors on reading back those values.

9317 returned string up to the first NUL character.
9318

9328
Georg Brandl3ee81df2008-05-17 18:14:43 +00009329- unittest now verifies more of its assumptions. In particular,
9330 TestCase and TestSuite subclasses (not instances) are no longer
9331 accepted in TestSuite.addTest(). This should cause no
9332 incompatibility since it never made sense with ordinary subclasses
9333 -- the failure just occurred later, with a more cumbersome
9334 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00009335

9344
Georg Brandl3ee81df2008-05-17 18:14:43 +00009345- Patch #1673619: setup.py identifies extension modules it doesn't

9699 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009716- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009717 time so that opening a database previously created with the DB_DUP
9718 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9719 opens. Specifically: dictionary assignment to a DB object will
9720 replace all values for a given key when the database allows
9721 duplicate values. DB users should use DB.put(k, v) when they want
9722 to store duplicates; not DB[k] = v.

9729 characters with ASCII value less than 32. Also, it correctly quotes
9730 dots only if they occur on a single line, as opposed to the previous
9731 behavior of quoting dots if they are the second character of any
9732 line.
