486
487- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
488 and later systems as is currently done for Python 3.x installers.
489 For 2.7.7 only, we will provide three installers:
490 the legacy deprecated 10.3+ 32-bit-only format;
491 the newer 10.5+ 32-bit-only format;
492 and the unchanged 10.6+ 64-/32-bit format.
493 Although binary installers will no longer be available from
494 python.org as of 2.7.8, it will still be possible to build from
495 source on 10.3.9 and 10.4 systems if necessary.
496 See Mac/BuildScript/README.txt for more information.

1874 In particular, fix extension module build failures when trying to use
1875 32-bit-only installer Pythons on systems with Xcode 4 (currently
1876 OS X 10.8, 10.7, and optionally 10.6).
1877 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1878 * Since Xcode 4 removes ppc support, extension module builds now
1879 check for ppc compiler support and by default remove ppc and
1880 ppc64 archs when they are not available.
1881 * Extension module builds now revert to using system installed
1882 headers and libs (/usr and /System/Library) if the SDK used
1883 to build the interpreter is not installed or has moved.
1884 * Try to avoid building extension modules with deprecated
1885 and problematic Apple llvm-gcc compiler. If original compiler
1886 is not available, use clang instead by default.

2320 64-bit/32-bit Pythons. If the user does not explicitly override
2321 the default C compiler by setting the CC environment variable,
2322 Distutils will now attempt to compile extension modules with clang
2323 if gcc-4.2 is required but not found. Also as a convenience, if
2324 the user does explicitly set CC, substitute its value as the default
2325 compiler in the Distutils LDSHARED configuration variable for OS X.
2326 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2327 SDK, neither of which are available in Xcode 4. This change does not
2328 attempt to override settings to support their use with Xcode 4.)

2579 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2580 interpreter process. This could cause failures in non-Distutils subprocesses
2581 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002582 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002583 deployment target only in the environment of each build subprocess. It is
2584 still possible to globally override the default by setting

Barry Warsawc5643282011-07-19 17:06:30 -04002615- sys.setcheckinterval() now updates the current ticker count as well as
2616 updating the check interval, so if the user decreases the check interval,
2617 the ticker doesn't have to wind down to zero from the old starting point
2618 before the new interval takes effect. And if the user increases the
2619 interval, it makes sure the new limit takes effect right away rather have an
2620 early task switch before recognizing the new interval.

3590 by Andrew Bennetts.

3599
Raymond Hettinger20397532010-09-12 02:11:45 +00003600- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3601 This prevents user-created self-referencing ordered dictionaries from
3602 becoming permanently uncollectable GC garbage. The downside is that
3603 removing __del__ means that the internal doubly-linked list has to wait for
3604 GC collection rather than freeing memory immediately when the refcnt drops
3605 to zero.
3606
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003607- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3610
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003611- Issue #9792: In case of connection failure, socket.create_connection()
3612 would swallow the exception and raise a new one, making it impossible
3613 to fetch the original errno, or to filter timeout errors. Now the
3614 original error is re-raised.
3615
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003616- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3617 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3618 be updated back after the system call. Original patch by Brian Brazil.

3625
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003626- Issue #808164: Fixed socket.close to avoid references to globals, to
3627 avoid issues when socket.close is called from a __del__ method.
3628

3630 can be set to False to turn off the previously undocumented 'popularity'
3631 heuristic. Patch by Terry Reedy and Eli Bendersky
3632
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003633- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3634 falling into recursion.
3635
R. David Murray7c4bf552010-08-25 01:45:57 +00003636- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3637 character years even if the message contains RFC822 two character years.
3638
Daniel Stutzbach91287322010-08-24 21:09:30 +00003639- Issue #8750: Fixed MutableSet's methods to correctly handle

3651 module now correctly return a set. (Patch by Eli Bendersky.)
3652
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003653- Issue #9617: Signals received during a low-level write operation aren't
3654 ignored by the buffered IO layer anymore.
3655
Benjamin Peterson52c36052010-08-21 03:03:22 +00003656- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3657 are not held onto after they are deleted elsewhere.
3658
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003659- Issue #9626: the view methods for collections.OrderedDict() were returning
3660 the unordered versions inherited from dict. Those methods are now
3661 overridden to provide ordered views.
3662
Éric Araujo0389ae62010-08-14 03:07:46 +00003663- Issue #8688: MANIFEST files created by distutils now include a magic
3664 comment indicating they are generated. Manually maintained MANIFESTs
3665 without this marker will not be overwritten or removed.
3666
Antoine Pitroue1436d12010-08-12 15:25:51 +00003667- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3668 and a BadZipfile error is raised if it doesn't match (as used to be the
3669 case in Python 2.5 and earlier).
3670
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003671- Issue #9550: a BufferedReader could issue an additional read when the
3672 original read request had been satisfied, which could block indefinitely
3673 when the underlying raw IO channel was e.g. a socket. Report and original
3674 patch by Jason V. Miller.
3675
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003676- Issue #9551: Don't raise TypeError when setting the value to None for

3695 This is how it is supposed to work, wget and curl do the same. Previous
3696 behavior was wrong.

3702
R. David Murray1cbf78e2010-08-03 18:14:01 +00003703- Issue #9444: Argparse now uses the first element of prefix_chars as
3704 the option character for the added 'h/help' option if prefix_chars
3705 does not contain a '-', instead of raising an error.
3706

4068 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4069 Previous versions returned a single u'\ufffd'.

4079 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

4329 indefinitely if the other end didn't respond.
4330
Georg Brandlfee0f442010-05-22 21:26:21 +00004331- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004424 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

4450
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004451- Issue #8329: Don't return the same lists from select.select when no fds are
4452 changed.
4453
Georg Brandlfee0f442010-05-22 21:26:21 +00004454- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004455 on 64-bit machines. The shift count for either left or right shift is
4456 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00004464- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4465 with a non-empty format string. This is an effort to future-proof user
4466 code. If a derived class does not currently implement __format__ but later
4467 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004468 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004469 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004519- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4520 InvalidOperation instead of returning False. (Comparisons involving a quiet
4521 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4522 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004523
Georg Brandlfee0f442010-05-22 21:26:21 +00004524- Issue #2531: Comparison operations between floats and Decimal instances now
4525 return a result based on the numeric values of the operands; previously they
4526 returned an arbitrary result based on the relative ordering of id(float) and
4527 id(Decimal).

4542 Fractions instance now raise TypeError instead of returning True/False. This
4543 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4544 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004962 file position when calling `truncate()`. It would previously change the file
4963 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004964 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4967 class used to represent files stored inside an archive. The new
4968 implementation is significantly faster and can be wrapped in a

4970 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00005061- The ``__complex__()`` method is now looked up on the class of instances to
5062 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005063
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005064- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5065 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5066
Mark Dickinson1b34d252010-01-01 17:27:30 +00005067- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005068 DeprecationWarning when passed a float argument where an integer was expected.
5069 These functions and methods now raise TypeError instead. The majority of the
5070 effects of this change are in the extension modules, but some core functions
5071 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5072 and many unicode/str methods.

5084
Georg Brandlba83f822010-03-14 09:50:54 +00005085- Issue #1811: Improve accuracy and cross-platform consistency for true division
5086 of integers: the result of a/b is now correctly rounded for ints a and b (at
5087 least on IEEE 754 platforms), and in particular does not depend on the
5088 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00005089
Georg Brandlba83f822010-03-14 09:50:54 +00005090- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00005095 executables on OSX.
5096
Georg Brandlba83f822010-03-14 09:50:54 +00005097 These executables now work properly with the arch(1) command: ``arch -ppc
5098 python`` will start a universal binary version of python in PPC mode (unlike
5099 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00005121 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00005261- Issue #7117: On almost all platforms: float-to-string and string-to-float
5262 conversions within Python are now correctly rounded. Places these conversions
5263 occur include: str for floats and complex numbers; the float and complex
5264 constructors; old-style and new-style numeric formatting; serialization and
5265 deserialization of floats and complex numbers using marshal, pickle and json;
5266 parsing of float and imaginary literals in Python code; Decimal-to-float
5267 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005268
Georg Brandlba83f822010-03-14 09:50:54 +00005269 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5270 providing correctly-rounded strtod and dtoa C functions. This code is
5271 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5272 the C compiler. There may be a small number of platforms on which correct
5273 operation of this code cannot be guaranteed, so the code is not used: notably,
5274 this applies to platforms where the C double format is not IEEE 754 binary64,
5275 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5276 and Python's configure script is unable to determine how to change the FPU
5277 precision. On these platforms conversions use the platform strtod and dtoa,
5278 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005280- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5281 uses the correctly-rounded string <-> float conversions described above (when
5282 available), and so produces correctly rounded results that will display nicely
5283 under the float repr. There are two related small changes: (1) round now
5284 accepts any class with an ``__index__()`` method for its second argument (but
5285 no longer accepts floats for the second argument), and (2) an excessively
5286 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5287 raises an exception.

6872 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6873 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6874 neither __int__ nor __long__, TypeError used to be raised (with a
6875 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6876 struct.error in other cases.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007073- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

7075 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7076 ``printf`` function, whereas PyString_FromFormat has an independent
7077 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007174 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7175 for catch_warnings() also led to an improvement in the raising of a
7176 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007242What's New in Python 2.6 beta 3?
7243================================
7244
Barry Warsaw07a4a382008-08-21 01:15:08 +00007245*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007246
7247Core and Builtins
7248-----------------
7249
Guido van Rossumf8402962008-08-20 15:01:50 +00007250- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7251 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7252 extensions do not automatically benefit from the class attribute
7253 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7254 to their tp_flags field if they care. This is a backwards
7255 compatibility feature; in 3.0, all types will use the cache by
7256 default.
7257
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007258- Keyword arguments can now follow starred arguments. (``f(a, *args,
7259 keyword=23)`` is now valid syntax.)
7260
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007261- ctypes function pointers that are COM methods have a boolean True
7262 value again.
7263
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007264- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7265 by denying s# to parse objects that have a releasebuffer procedure,
7266 and introducing s*.
7267
Georg Brandl1e13ea92008-08-11 09:07:59 +00007268- Issue #3537: Fix an assertion failure when an empty but presized dict
7269 object was stored in the freelist.
7270
Mark Dickinsonb6467572008-08-04 21:30:09 +00007271- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7272 ValueError consistently across platforms.
7273
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007274- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7275 (64bit Unix, for example), unichr() would truncate its argument and return
7276 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7277
Neal Norwitze7d8be82008-07-31 17:17:14 +00007278- Apply security patches from Apple.
7279
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007280- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7281 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7282
Antoine Pitrou92f82162008-07-25 22:22:08 +00007283- Issue #1819: function calls with several named parameters are now on
7284 average 35% faster (as measured by pybench).
7285
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007286- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7287 the python debugger steps into a class statement: the free variables (local
7288 variables defined in an outer scope) would be deleted from the outer scope.
7289
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007290- Issue #2620: Overflow checking when allocating or reallocating memory
7291 was not always being done properly in some python types and extension
7292 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7293 all been updated to perform better checks and places in the code that
7294 would previously leak memory on the error path when such an allocation
7295 failed have been fixed.

7299
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007300- Issue #3612: Added some missing basic types in ctypes.wintypes.
7301
Benjamin Petersone977ad42008-08-20 01:42:01 +00007302- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7303 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7304
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007305- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7306 version reported by these tools does not necessarily follow the python
7307 version numbering scheme, so the module is less strict when parsing it.
7308
Nick Coghlanf70385a2008-08-18 12:42:46 +00007309- Issue #2235: Added Py3k warnings for types which will become unhashable
7310 under the stricter __hash__ inheritance rules in 3.0. Several types
7311 which did not meet the rules for hash invariants and were already
7312 unhashable in 3.0 have now been explicitly flagged as unhashable in
7313 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7314 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7315
Brett Cannon88f801d2008-08-18 00:46:22 +00007316- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7317 imported into the module but exposed as part of the module's API.
7318
Brett Cannon7b96f072008-08-18 00:41:11 +00007319- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7320
Brett Cannon46225e72008-08-18 00:36:52 +00007321- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007323- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7324
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007325- Issue #3575: Incremental decoder's decode function now takes bytearray
7326 by using 's*' instead of 't#'.
7327
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007328- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007329 fails unicode conversion on 2nd parameter. (windows only)
7330
Georg Brandl222e2082010-08-01 22:27:39 +00007331- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007332 in a redirect.
7333
Brett Cannonabe423e2008-08-16 21:47:07 +00007334- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007335 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007336
Facundo Batistaeb90b782008-08-16 14:44:07 +00007337- Issue #2776: fixed small issue when handling an URL with double slash
7338 after a 302 response in the case of not going through a proxy.
7339
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007340- Issue #2676: in the email package, content-type parsing was hanging on
7341 pathological input because of quadratic or exponential behaviour of a
7342 regular expression.
7343
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007344- Issue #3476: binary buffered reading through the new "io" library is now
7345 thread-safe.
7346
Brett Cannonbf3157b2008-08-14 05:00:03 +00007347- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7348 since mimetools itself is deprecated. Because modules are cached, all
7349 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7350
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007351- Issue #3134: shutil referenced undefined WindowsError symbol.
7352
Robert Schuppenies14646332008-08-10 11:01:53 +00007353- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7354 menu entries were not deleted.
7355
Brett Cannon83e81842008-08-09 23:30:55 +00007356- Copied the implementation of reduce() to _functools.reduce() to have a
7357 version that did not raise a DeprecationWarning under -3.
7358
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007359- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7360 a MemoryError rather than silently stop the iteration.
7361
Guido van Rossum59ce9012008-08-09 14:55:34 +00007362- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7363 to _sre.compile() will now be rejected. This should not affect anybody
7364 since the re.compile() function never generates invalid re-bytecode.
7365
Skip Montanaroa032bf42008-08-08 22:52:51 +00007366- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7367 upon first access it can be automatically initialized from the csv file if
7368 it wasn't initialized during instantiation.
7369
Brett Cannon3aa2a492008-08-06 22:28:09 +00007370- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7371 the reload() built-in has been removed.
7372
Brett Cannon7e30b672008-08-04 21:52:25 +00007373- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007374 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007385 asking for a specific length. This problem only affected files opened
7386 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007387

7442-----------------
7443
Georg Brandl3e483f62008-07-16 22:57:41 +00007444- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7445 its methods now allow for items objects that can be converted to
7446 an integer using operator.index().
7447
Mark Dickinson64b7e502008-07-16 09:40:03 +00007448- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7449 produced a ValueError instead of giving the correct float.
7450
Eric Smitha5fa5a22008-07-16 00:11:49 +00007451- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7452 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7453
Mark Dickinson7103aa42008-07-15 19:08:33 +00007454- Issue #3008: the float type has a new instance method 'float.hex'
7455 and a new class method 'float.fromhex' to convert floating-point
7456 numbers to and from hexadecimal strings, respectively.
7457
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007458- Issue #2235: __hash__ is once again inherited by default. To allow
7459 collections.Hashable to remain meaningful in the presence of the
7460 default hash implementation (object.__hash__), it is now possible
7461 to explicit block inheritance of hash by setting __hash__=None at
7462 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7463 level.
7464
Nick Coghlanb028f502008-07-13 14:52:36 +00007465- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7466 the parent module cannot be found while performing an absolute import.
7467 This means that an incorrectly defined __package__ attribute will
7468 now only prevent relative imports in that module rather than causing
7469 all imports from that module to fail.
7470
Nick Coghlan14ff9942008-07-08 14:21:42 +00007471- Issue #2517: Allow unicode messages in Exceptions again by correctly

7481 another thread's dictionary.
7482
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007483- Issue #3004: Minor change to slice.indices(): the start and stop
7484 arguments are now treated identically, making the behaviour easier
7485 to describe and understand. For example, slice(None, -10,
7486 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7487 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7488 10, -1).
7489
Georg Brandl278fc502008-07-19 12:46:12 +00007490- Issue #3219: Calling a function with repeated keyword arguments,
7491 f(a=2, a=23), would not cause a syntax error. This was a regression
7492 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007493
Georg Brandl278fc502008-07-19 12:46:12 +00007494- Issue #2862: Make int and float freelist management consistent with
7495 other freelists. Changes their CompactFreeList apis into

7502 api functions without holding the GIL, which could lead to a fatal
7503 error when they failed.
7504
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007505- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007530- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7531 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007532 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007533 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007549- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00008001- Issue #1631171: Re-implement the 'warnings' module in C (the
8002 original Python code has been kept as backup). This will allow for
8003 using the 'warning's machinery in such places as the parser where
8004 use of pure Python code is not possible. Both the ``showarning()``
8005 and ``formatwarning()`` gain an optional 'line' argument which is
8006 not called by default for backwards-compatibility reasons. Setting
8007 ``warnings.showwarning()`` to an implementation that lacks support
8008 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008071- Issue #2550: The approach used by client/server code for obtaining
8072 ports to listen on in network-oriented tests has been refined in an
8073 effort to facilitate running multiple instances of the entire
8074 regression test suite in parallel without issue.
8075 test_support.bind_port() has been fixed such that it will always
8076 return a unique port -- which wasn't always the case with the
8077 previous implementation, especially if socket options had been set
8078 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8079 new implementation of bind_port() will actually raise an exception
8080 if it is passed an AF_INET/SOCK_STREAM socket with either the
8081 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8082 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8083 the socket it's been passed. This currently only applies to
8084 Windows. This option prevents any other sockets from binding to the
8085 host/port we've bound to, thus removing the possibility of the
8086 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8087 when a second SOCK_STREAM socket binds and accepts to a host/port
8088 that's already been bound by another socket. The optional preferred
8089 port parameter to bind_port() has been removed. Under no
8090 circumstances should tests be hard coding ports!
8091
8092 test_support.find_unused_port() has also been introduced, which will
8093 pass a temporary socket object to bind_port() in order to obtain an
8094 unused port. The temporary socket object is then closed and
8095 deleted, and the port is returned. This method should only be used
8096 for obtaining an unused port in order to pass to an external program
8097 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8098 a parameter to a server-oriented class that doesn't give you direct
8099 access to the underlying socket used.
8100
8101 Finally, test_support.HOST has been introduced, which should be used
8102 for the host argument of any relevant socket calls (i.e. bind and
8103 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008104
8105 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008106 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008107 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8108 test_asynchat and test_socket_ssl.
8109
Georg Brandl3ee81df2008-05-17 18:14:43 +00008110 It is now possible for multiple instances of the regression test
8111 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008390- Added the future_builtins module, which contains hex() and oct().
8391 These are the PEP 3127 version of these functions, designed to be
8392 compatible with the hex() and oct() builtins from Python 3.0. They
8393 differ slightly in their output formats from the existing, unchanged
8394 Python 2.6 builtins. The expected usage of the future_builtins
8395 module is:
8396 from future_builtins import hex, oct
8397
Eric Smith7ef40bf2008-02-20 23:34:22 +00008398- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8399 exponents for exponents with absolute value < 100. Follows C99
8400 standard. This is a change on Windows, which would use 3 digits.
8401 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8402 so that any alterations it does to the resulting string will be
8403 available in stringlib/formatter.h (for float.__format__).
8404
Eric Smith5a3c1352008-02-19 13:21:56 +00008405- Implemented PEP 3101, Advanced String Formatting. This adds a new
8406 builtin format(); a format() method for str and unicode; a
8407 __format__() method to object, str, unicode, int, long, float, and
8408 datetime; the class string.Formatter; and the C API
8409 PyObject_Format().
8410
Georg Brandl3ee81df2008-05-17 18:14:43 +00008411- Fixed several potential crashes, all caused by specially crafted
8412 __del__ methods exploiting objects in temporarily inconsistent
8413 state.

8424 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008425
Georg Brandl3ee81df2008-05-17 18:14:43 +00008426- Issue #2045: Fix an infinite recursion triggered when printing a
8427 subclass of collections.defaultdict, if its default_factory is set
8428 to a bound method.

8439
Georg Brandl3ee81df2008-05-17 18:14:43 +00008440- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8441 calls. Python expected the return type int but the fork familie
8442 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008456- Patch #1473257: generator objects gain a gi_code attribute. This is
8457 the same object as the func_code attribute of the function that
8458 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008459
Georg Brandl3ee81df2008-05-17 18:14:43 +00008460- Issue #1920: "while 0" statements were completely removed by the
8461 compiler, even in the presence of an "else" clause, which is
8462 supposed to be run when the condition is false. Now the compiler
8463 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008464

8481
Georg Brandl6caad7d2008-01-26 14:19:22 +00008482- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008483 added.
8484
Christian Heimesc94e2b52008-01-14 04:13:37 +00008485- sys.float_info / PyFloat_GetInfo: The floating point information
8486 object was converted from a dict to a specialized structseq object.
8487
Georg Brandl3ee81df2008-05-17 18:14:43 +00008488- Patch #1816: Added sys.flags structseq. It exposes the status of
8489 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008490
Georg Brandl3ee81df2008-05-17 18:14:43 +00008491- Objects/structseq.c: Implemented new structseq representation. The
8492 patch makes structseqs (e.g. the return value of os.stat) more
8493 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008494
Georg Brandl3ee81df2008-05-17 18:14:43 +00008495- Patch #1700288: added a type attribute cache that caches method
8496 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008497
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008498- Bug #1776: __import__() no longer accepts filenames on any platform.
8499 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00008501- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8502
Georg Brandl3ee81df2008-05-17 18:14:43 +00008503- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8504 envvar and sys.dont_write_bytecode attribute. All these can be set
8505 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008506
Georg Brandl3ee81df2008-05-17 18:14:43 +00008507- Improve some exception messages when Windows fails to load an
8508 extension module. Now we get for example '%1 is not a valid Win32
8509 application' instead of 'error code 193'.

8514 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008515
Christian Heimes0a8143f2007-12-18 23:22:54 +00008516- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008517 and INF. float("nan"), float("inf") and float("-inf") now work on
8518 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008520- Compiler now generates simpler and faster code for dictionary
8521 literals. The oparg for BUILD_MAP now indicates an estimated
8522 dictionary size. There is a new opcode, STORE_MAP, for adding
8523 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008552- Patch #1739468: Directories and zipfiles containing a __main__.py
8553 file can now be directly executed by passing their name to the
8554 interpreter. The directory/zipfile is automatically inserted as the
8555 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008556
Georg Brandl3ee81df2008-05-17 18:14:43 +00008557- Issue #1265: Fix a problem with sys.settrace, if the tracing
8558 function uses a generator expression when at the same time the
8559 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008560
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008561- sets and frozensets now have an isdisjoint() method.
8562
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008563- optimize the performance of builtin.sum().
8564
Neal Norwitz44f326e2007-10-05 05:29:17 +00008565- Fix warnings found by the new version of the Coverity checker.
8566
Georg Brandl21e99f42010-03-07 15:23:59 +00008567- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008568 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8569 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008570
Georg Brandl3ee81df2008-05-17 18:14:43 +00008571- Issue #1686386: Tuple's tp_repr did not take into account the
8572 possibility of having a self-referential tuple, which is possible
8573 from C code. Nor did object's tp_str consider that a type's tp_str
8574 could do something that could lead to an inifinite recursion.
8575 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8576 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008577
Georg Brandl3ee81df2008-05-17 18:14:43 +00008578- Issue #1164: It was possible to trigger deadlock when using the
8579 'print' statement to write to a file since the GIL was not released
8580 as needed. Now PyObject_Print() does the right thing along with
8581 various tp_print implementations of the built-in types and those in
8582 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008583
Georg Brandl3ee81df2008-05-17 18:14:43 +00008584- Issue #1147: Exceptions were directly allowing string exceptions in
8585 their throw() method even though string exceptions no longer
8586 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008587
Georg Brandl3ee81df2008-05-17 18:14:43 +00008588- Issue #1096: Prevent a segfault from getting the repr of a very
8589 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008590
Brett Cannon1e534b52007-09-07 04:18:30 +00008591- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008592 PyObject_Call() never calling back out to Python code to trigger
8593 recursion depth updates/checks. Required the creation of a static
8594 RuntimeError instance in case normalizing an exception put the
8595 recursion check value past its limit. Fixes crashers
8596 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008597

Neal Norwitz0ac60192007-05-27 04:08:54 +00008611- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008612 __*__ attributes. (Some already existed, e.g., __doc__ and
8613 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008614
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008615- Add -3 option to the interpreter to warn about features that are
8616 deprecated and will be changed/removed in Python 3.0.
8617
Georg Brandl2134e752007-05-21 20:34:16 +00008618- Patch #1686487: you can now pass any mapping after '**' in function
8619 calls.
8620
Collin Winter62903052007-05-18 23:11:24 +00008621- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008622 "except E as target:". This is to provide forwards compatibility
8623 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008624
Brett Cannon229cee22007-05-05 01:34:02 +00008625- Deprecate BaseException.message as per PEP 352.
8626
Georg Brandl3ee81df2008-05-17 18:14:43 +00008627- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008628 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008629
Vinay Sajip8549ce32007-05-06 17:53:37 +00008630- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008631 setting a plain string, ie don't expand to single letter identifiers.
8632
Raymond Hettinger13936692007-04-11 18:40:58 +00008633- Request #1191699: Slices can now be pickled.
8634
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008635- Request #1193128: str.translate() now allows a None argument for
8636 translations that only remove characters without re-mapping the
8637 remaining characters.
8638
Georg Brandl5cb76c12007-03-21 09:00:39 +00008639- Patch #1682205: a TypeError while unpacking an iterable is no longer
8640 masked by a generic one with the message "unpack non-sequence".
8641
Neal Norwitzaa754b72007-03-21 06:39:48 +00008642- Remove unused file Python/fmod.c.
8643
Guido van Rossum143b5642007-03-23 04:58:42 +00008644- Bug #1683368: The object.__init__() and object.__new__() methods are
8645 now stricter in rejecting excess arguments. The only time when
8646 either allows excess arguments is when it is not overridden and the
8647 other one is. For backwards compatibility, when both are
8648 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008649 warning later). Also, type.__init__() insists on the same signature
8650 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008651
Georg Brandl3ee81df2008-05-17 18:14:43 +00008652- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8653 object to complex using its __complex__() method before falling back
8654 to the __float__() method. Therefore, the functions in the cmath
8655 module now can operate on objects that define a __complex__()
8656 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008657
Georg Brandl3ee81df2008-05-17 18:14:43 +00008658- Patch #1623563: allow __class__ assignment for classes with
8659 __slots__. The old and the new class are still required to have the
8660 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008661
Georg Brandl3ee81df2008-05-17 18:14:43 +00008662- Patch #1642547: Fix an error/crash when encountering syntax errors

8666 ``object.__reduce_ex__()`` is called with an object that is faking
8667 its type.

8673
Georg Brandl7b9c5552007-03-12 14:30:05 +00008674- Bug #1678647: write a newline after printing an exception in any
8675 case, even when converting the value to a string failed.
8676
Georg Brandl871f1bc2007-03-12 13:17:36 +00008677- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008678 its argument, if it exists. If not, it will work like before. This
8679 allows customizing the output of dir() in the presence of a
8680 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008688- Patch #1491866: change the complex() constructor to allow
8689 parthensized forms. This means complex(repr(x)) now works instead of
8690 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008691
Georg Brandlaa2321b2007-03-07 00:40:28 +00008692- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008693 makes the filenames the warning module prints much more sensible
8694 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008695

8697 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008698 variable is given, but break into the interactive interpreter just
8699 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008707- Patch #1674228: when assigning a slice (old-style), check for the
8708 sq_ass_slice instead of the sq_slice slot.
8709
Georg Brandl3ee81df2008-05-17 18:14:43 +00008710- When printing an unraisable error, don't print exceptions. before
8711 the name. This duplicates the behavior whening normally printing
8712 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00009213- Added a timeout parameter to the constructor of other protocols
9214 (telnetlib, ftplib, smtplib and poplib). This is second part of the
9215 work started with create_connection() and timeout in httplib, and
9216 closes patch #723312.
9217
Vinay Sajip8549ce32007-05-06 17:53:37 +00009218- Patch #1676823: Added create_connection() to socket.py, which may be
9219 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00009220 and HTTPSConnection now accept an optional timeout).

9242
Georg Brandlf66b6032007-03-14 08:27:52 +00009243- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00009244 AttributeError instead of an IOError when the server's response
9245 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00009246
Georg Brandl3ee81df2008-05-17 18:14:43 +00009247- Patch #957650: "%var%" environment variable references are now

Georg Brandl3ee81df2008-05-17 18:14:43 +00009251- Patch #1429539: pdb now correctly initializes the __main__ module
9252 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00009253 correctly now.
9254

9261
Georg Brandl3ee81df2008-05-17 18:14:43 +00009262- Patch #1530482: add pydoc.render_doc() which returns the

9273 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00009275- Patch #1581073: add a flag to textwrap that prevents the dropping of

9277
Georg Brandl92a6bae2007-03-13 17:43:32 +00009278- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009279 are set for invalid interpolation sequences that would lead to
9280 errors on reading back those values.

9323 returned string up to the first NUL character.

9334
Georg Brandl3ee81df2008-05-17 18:14:43 +00009335- unittest now verifies more of its assumptions. In particular,
9336 TestCase and TestSuite subclasses (not instances) are no longer
9337 accepted in TestSuite.addTest(). This should cause no
9338 incompatibility since it never made sense with ordinary subclasses
9339 -- the failure just occurred later, with a more cumbersome
9340 exception.

9350
Georg Brandl3ee81df2008-05-17 18:14:43 +00009351- Patch #1673619: setup.py identifies extension modules it doesn't

9705 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009722- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009723 time so that opening a database previously created with the DB_DUP
9724 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9725 opens. Specifically: dictionary assignment to a DB object will
9726 replace all values for a given key when the database allows
9727 duplicate values. DB users should use DB.put(k, v) when they want
9728 to store duplicates; not DB[k] = v.

9735 characters with ASCII value less than 32. Also, it correctly quotes
9736 dots only if they occur on a single line, as opposed to the previous
9737 behavior of quoting dots if they are the second character of any
9738 line.
