184 int.__pow__. These overflow checks were causing int.__pow__ to produce
185 incorrect results with recent versions of Clang, as a result of the

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

200 cleared by the garbage collector. This fixes a segfault when an instance
201 and its type get caught in a reference cycle, and the instance's

264 Distutils-based packages with C extension modules may fail because
265 Apple has removed gcc-4.2, the version used to build python.org
266 64-bit/32-bit Pythons. If the user does not explicitly override
267 the default C compiler by setting the CC environment variable,
268 Distutils will now attempt to compile extension modules with clang
269 if gcc-4.2 is required but not found. Also as a convenience, if
270 the user does explicitly set CC, substitute its value as the default
271 compiler in the Distutils LDSHARED configuration variable for OS X.
272 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
273 SDK, neither of which are available in Xcode 4. This change does not
274 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700547- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
548 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
549 interpreter process. This could cause failures in non-Distutils subprocesses
550 and was unreliable since tests or user programs could modify the interpreter
551 environment after Distutils set it. Instead, have Distutils set the the
552 deployment target only in the environment of each build subprocess. It is
553 still possible to globally override the default by setting
554 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
555 greater or equal to the default value, the value with which the interpreter
556 was built.

586 the ticker doesn't have to wind down to zero from the old starting point
587 before the new interval takes effect. And if the user increases the
588 interval, it makes sure the new limit takes effect right away rather have an

1499
R. David Murray20ad3632010-10-01 15:48:49 +00001500- Issue #10004: quoprimime no longer generates a traceback when confronted
1501 with invalid characters after '=' in a Q-encoded word.
1502
Antoine Pitrou66b5df62010-09-27 18:16:46 +00001503- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
1504 received. Now sendall() properly calls signal handlers if necessary,
1505 and retries sending if these returned successfully, including on sockets
1506 with a timeout.

1517 handles non-blocking readinto() returning None correctly.
1518

1520 SSLSocket.sendto() to match the corresponding socket methods. Also,
1521 fix various SSLSocket methods to raise socket.error rather than an
1522 unhelpful TypeError when called on an unconnected socket. Original patch
1523 by Andrew Bennetts.
1524

1532
Raymond Hettinger20397532010-09-12 02:11:45 +00001533- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1534 This prevents user-created self-referencing ordered dictionaries from
1535 becoming permanently uncollectable GC garbage. The downside is that
1536 removing __del__ means that the internal doubly-linked list has to wait for
1537 GC collection rather than freeing memory immediately when the refcnt drops
1538 to zero.
1539
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001540- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00001541 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001542 value.
1543
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001544- Issue #9792: In case of connection failure, socket.create_connection()
1545 would swallow the exception and raise a new one, making it impossible
1546 to fetch the original errno, or to filter timeout errors. Now the
1547 original error is re-raised.
1548
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001549- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
1550 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
1551 be updated back after the system call. Original patch by Brian Brazil.
1552
Antoine Pitroudca9de92010-09-04 17:52:26 +00001553- Issue #1100562: Fix deep-copying of objects derived from the list and
1554 dict types. Patch by Michele Orrù and Björn Lindqvist.

1557 ConfigParser.write.
1558
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00001559- Issue #808164: Fixed socket.close to avoid references to globals, to
1560 avoid issues when socket.close is called from a __del__ method.
1561
Terry Reedyd2d2ae92010-11-11 23:22:19 +00001562- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
1563 can be set to False to turn off the previously undocumented 'popularity'
1564 heuristic. Patch by Terry Reedy and Eli Bendersky
1565
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00001566- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
1567 falling into recursion.
1568
R. David Murray7c4bf552010-08-25 01:45:57 +00001569- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1570 character years even if the message contains RFC822 two character years.
1571
Daniel Stutzbach91287322010-08-24 21:09:30 +00001572- Issue #8750: Fixed MutableSet's methods to correctly handle
1573 reflexive operations, namely x -= x and x ^= x.

Raymond Hettinger917bba12010-08-22 08:01:58 +00001583- Issue #9214: Set operations on KeysView or ItemsView in the collections
1584 module now correctly return a set. (Patch by Eli Bendersky.)
1585
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001586- Issue #9617: Signals received during a low-level write operation aren't
1587 ignored by the buffered IO layer anymore.
1588
Benjamin Peterson52c36052010-08-21 03:03:22 +00001589- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
1590 are not held onto after they are deleted elsewhere.
1591
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001592- Issue #9626: the view methods for collections.OrderedDict() were returning

1603
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001604- Issue #9550: a BufferedReader could issue an additional read when the
1605 original read request had been satisfied, which could block indefinitely
1606 when the underlying raw IO channel was e.g. a socket. Report and original
1607 patch by Jason V. Miller.
1608
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001609- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00001627- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
1628 This is how it is supposed to work, wget and curl do the same. Previous
1629 behavior was wrong.

1637 the option character for the added 'h/help' option if prefix_chars
1638 does not contain a '-', instead of raising an error.
1639

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002358 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

2381-----------------
2382
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002383- Issue #7301: Add environment variable $PYTHONWARNINGS.
2384
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002385- Issue #8329: Don't return the same lists from select.select when no fds are
2386 changed.
2387
Georg Brandlfee0f442010-05-22 21:26:21 +00002388- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002389 on 64-bit machines. The shift count for either left or right shift is
2390 permitted to be up to sys.maxsize.
2391
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002392- Ensure that tokenization of identifiers is not affected by locale.
2393
Georg Brandlfee0f442010-05-22 21:26:21 +00002394- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002395
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002396- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2397
Georg Brandlfee0f442010-05-22 21:26:21 +00002398- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2399 with a non-empty format string. This is an effort to future-proof user
2400 code. If a derived class does not currently implement __format__ but later
2401 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002402 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002403 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002404
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002405- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002418- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002419 (SIGINT). If an error occurs while importing the site module, the error is

2435
Georg Brandlfee0f442010-05-22 21:26:21 +00002436- Issue #8257: The Decimal construct now accepts a float instance directly,
2437 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002438
2439 >>> Decimal(1.1)
2440 Decimal('1.100000000000000088817841970012523233890533447265625')
2441
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002442- collections.Counter() now supports a subtract() method.
2443
Georg Brandlfee0f442010-05-22 21:26:21 +00002444- The functools module now has a total_ordering() class decorator to simplify
2445 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002446
Georg Brandlfee0f442010-05-22 21:26:21 +00002447- The functools module also adds cmp_to_key() as a tool to transition old-style
2448 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002449
Georg Brandlfee0f442010-05-22 21:26:21 +00002450- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2451 directly.

Georg Brandlfee0f442010-05-22 21:26:21 +00002453- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2454 InvalidOperation instead of returning False. (Comparisons involving a quiet
2455 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2456 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002457
Georg Brandlfee0f442010-05-22 21:26:21 +00002458- Issue #2531: Comparison operations between floats and Decimal instances now
2459 return a result based on the numeric values of the operands; previously they
2460 returned an arbitrary result based on the relative ordering of id(float) and
2461 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002462
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002463- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002464 argument `-` which tells it to read files to compile from stdin. Each line is
2465 read on demand and the named file is compiled immediately. (Original patch by
2466 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002471- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2472 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002473 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002474
Georg Brandlfee0f442010-05-22 21:26:21 +00002475- Comparisons using one of <, <=, >, >= between a complex instance and a
2476 Fractions instance now raise TypeError instead of returning True/False. This
2477 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2478 <=> complex, and complex <=> complex comparisons.

2587 the set of integer codes for which it was used differed between native packing
2588 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002896 file position when calling `truncate()`. It would previously change the file
2897 position to the given argument, which goes against the tradition of

2901 class used to represent files stored inside an archive. The new
2902 implementation is significantly faster and can be wrapped in a

2904 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2917 encoded string for them. This ensures that the upload and register commands
2918 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003189- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3190 decimal string that's guaranteed to round back to x under correct rounding
3191 (with round-half-to-even rounding mode). Previously it gave a string based on
3192 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3193 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3194 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003195
Georg Brandlba83f822010-03-14 09:50:54 +00003196- Issue #7117: On almost all platforms: float-to-string and string-to-float
3197 conversions within Python are now correctly rounded. Places these conversions
3198 occur include: str for floats and complex numbers; the float and complex
3199 constructors; old-style and new-style numeric formatting; serialization and
3200 deserialization of floats and complex numbers using marshal, pickle and json;
3201 parsing of float and imaginary literals in Python code; Decimal-to-float
3202 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003203
Georg Brandlba83f822010-03-14 09:50:54 +00003204 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3205 providing correctly-rounded strtod and dtoa C functions. This code is
3206 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3207 the C compiler. There may be a small number of platforms on which correct
3208 operation of this code cannot be guaranteed, so the code is not used: notably,
3209 this applies to platforms where the C double format is not IEEE 754 binary64,
3210 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3211 and Python's configure script is unable to determine how to change the FPU
3212 precision. On these platforms conversions use the platform strtod and dtoa,
3213 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003215- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3216 uses the correctly-rounded string <-> float conversions described above (when
3217 available), and so produces correctly rounded results that will display nicely
3218 under the float repr. There are two related small changes: (1) round now
3219 accepts any class with an ``__index__()`` method for its second argument (but
3220 no longer accepts floats for the second argument), and (2) an excessively
3221 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3222 raises an exception.

3371 but with at least one decimal point and with a default precision
3372 of 12. Previously, the behavior the same but with a default precision of 6.
3373 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandl29c6a282009-04-05 20:23:13 +00003484- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00003485 were suppressing all exceptions. These include list(), filter(), map(),

3487
Benjamin Peterson596d3062009-01-19 15:42:23 +00003488- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00003515- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3516 existing .py counterpart, override the co_filename attributes of all code
3517 objects if the original filename is obsolete (which can happen if the file has

3572
Georg Brandlba83f822010-03-14 09:50:54 +00003573- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3574 file objects with closefd=False. The file descriptor is still kept open but
3575 the file object behaves like a closed file. The ``FileIO`` object also got a
3576 new readonly attribute ``closefd``.

3595
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003596- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003599- On windows, ``os.chdir()`` given unicode was not working if
3600 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3601 this code path is really executed because I cannot move to such directory on
3602 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003604- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3605 element is temporarily replaced with an equivalent frozenset. But the
3606 eventual KeyError would always report the empty ``frozenset()`` as the missing
3607 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003627- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3628 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3629 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3630 of using the replace error handler in PyUnicode_DecodeUTF8().
3631
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003632- Issue #3739: The unicode-internal encoder now reports the number of characters

3634
Georg Brandlba83f822010-03-14 09:50:54 +00003635- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3637 gives improved memory leak detection when running under Valgrind, while taking
3638 advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00003710 __main__.py file. This allows applications that run other Python scripts to
3711 support the same flexibility as the CPython command line itself.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005003- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5004
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005005- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5006 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5007 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5008 ``printf`` function, whereas PyString_FromFormat has an independent
5009 implementation and uses "%zd" on all platforms for size_t values.
5010 This makes a difference on win64, where ``printf`` needs "%Id" to display
5011 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005013- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5017 object; previously an int would be returned for small values. the __long__
5018 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005028 was correctly parsed but parsing of subsequent arguments failed.
5029
Vinay Sajip35e3b032008-09-01 14:33:59 +00005030- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005031 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5032 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5033 when given a tuple of classes as second argument, were looking up
5034 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5035 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005106 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5107 for catch_warnings() also led to an improvement in the raising of a
5108 DeprecationWarning related to warnings.warn_explicit().
5109
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005110- The deprecation warnings for the old camelCase threading API were removed.
5111

5113
Christian Heimesa27a62e2008-08-22 19:55:54 +00005114- Silenced a trivial compiler warning in the sqlite module.
5115
Christian Heimes1cc69632008-08-22 20:10:27 +00005116- Fixed two format strings in the _collections module.
5117
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005118- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a

Gregory P. Smithd7122032008-09-02 05:36:11 +00005121- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
5122 non-integer floating point number.
5123
Vinay Sajip65d66e12008-09-04 07:31:21 +00005124- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

Jesse Noller438195f2009-01-18 21:04:36 +00005130- Issue #4301: Patch the logging module to add processName support, remove
5131 _check_logger_class from multiprocessing.
5132
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005133- Issue #2975: When compiling several extension modules with Visual Studio 2008
5134 from the same python interpreter, some environment variables would grow
5135 without limit.
5136
Benjamin Peterson37346b22008-08-23 20:27:43 +00005137- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5138 exploitation of poor argument checking.
5139
Gerhard Häringef2276b2008-09-12 13:54:06 +00005140- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
5141
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00005142- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
5143 remaining ones have "pysqlite_" prefix.
5144
Gerhard Häringe6872eb2008-09-12 22:33:22 +00005145- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

5153 wrapper for warnings.catch_warnings() that makes it easier to check
5154 that expected warning messages are being reported.
5155
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00005156- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005174What's New in Python 2.6 beta 3?
5175================================
5176
Barry Warsaw07a4a382008-08-21 01:15:08 +00005177*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005178
5179Core and Builtins
5180-----------------
5181
Guido van Rossumf8402962008-08-20 15:01:50 +00005182- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5183 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5184 extensions do not automatically benefit from the class attribute
5185 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5186 to their tp_flags field if they care. This is a backwards
5187 compatibility feature; in 3.0, all types will use the cache by
5188 default.
5189
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005190- Keyword arguments can now follow starred arguments. (``f(a, *args,
5191 keyword=23)`` is now valid syntax.)
5192
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005193- ctypes function pointers that are COM methods have a boolean True
5194 value again.
5195
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005196- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5197 by denying s# to parse objects that have a releasebuffer procedure,
5198 and introducing s*.
5199
Georg Brandl1e13ea92008-08-11 09:07:59 +00005200- Issue #3537: Fix an assertion failure when an empty but presized dict
5201 object was stored in the freelist.
5202
Mark Dickinsonb6467572008-08-04 21:30:09 +00005203- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5204 ValueError consistently across platforms.
5205
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005206- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5207 (64bit Unix, for example), unichr() would truncate its argument and return
5208 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5209
Neal Norwitze7d8be82008-07-31 17:17:14 +00005210- Apply security patches from Apple.
5211
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005212- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5213 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5214
Antoine Pitrou92f82162008-07-25 22:22:08 +00005215- Issue #1819: function calls with several named parameters are now on
5216 average 35% faster (as measured by pybench).
5217
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005218- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5219 the python debugger steps into a class statement: the free variables (local
5220 variables defined in an outer scope) would be deleted from the outer scope.
5221
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005222- Issue #2620: Overflow checking when allocating or reallocating memory
5223 was not always being done properly in some python types and extension
5224 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5225 all been updated to perform better checks and places in the code that
5226 would previously leak memory on the error path when such an allocation
5227 failed have been fixed.
5228
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005229Library
5230-------
5231
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005232- Issue #3612: Added some missing basic types in ctypes.wintypes.
5233
Benjamin Petersone977ad42008-08-20 01:42:01 +00005234- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5235 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5236
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005237- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5238 version reported by these tools does not necessarily follow the python
5239 version numbering scheme, so the module is less strict when parsing it.
5240
Nick Coghlanf70385a2008-08-18 12:42:46 +00005241- Issue #2235: Added Py3k warnings for types which will become unhashable
5242 under the stricter __hash__ inheritance rules in 3.0. Several types
5243 which did not meet the rules for hash invariants and were already
5244 unhashable in 3.0 have now been explicitly flagged as unhashable in
5245 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5246 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5247
Brett Cannon88f801d2008-08-18 00:46:22 +00005248- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5249 imported into the module but exposed as part of the module's API.
5250
Brett Cannon7b96f072008-08-18 00:41:11 +00005251- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005255- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5256
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005257- Issue #3575: Incremental decoder's decode function now takes bytearray
5258 by using 's*' instead of 't#'.
5259
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005260- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005261 fails unicode conversion on 2nd parameter. (windows only)
5262
Georg Brandl222e2082010-08-01 22:27:39 +00005263- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005264 in a redirect.
5265
Brett Cannonabe423e2008-08-16 21:47:07 +00005266- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005267 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005268
Facundo Batistaeb90b782008-08-16 14:44:07 +00005269- Issue #2776: fixed small issue when handling an URL with double slash
5270 after a 302 response in the case of not going through a proxy.
5271
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005272- Issue #2676: in the email package, content-type parsing was hanging on
5273 pathological input because of quadratic or exponential behaviour of a
5274 regular expression.
5275
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005276- Issue #3476: binary buffered reading through the new "io" library is now
5277 thread-safe.
5278
Brett Cannonbf3157b2008-08-14 05:00:03 +00005279- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5280 since mimetools itself is deprecated. Because modules are cached, all
5281 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5282
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005283- Issue #3134: shutil referenced undefined WindowsError symbol.
5284
Robert Schuppenies14646332008-08-10 11:01:53 +00005285- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5286 menu entries were not deleted.
5287
Brett Cannon83e81842008-08-09 23:30:55 +00005288- Copied the implementation of reduce() to _functools.reduce() to have a
5289 version that did not raise a DeprecationWarning under -3.
5290
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005291- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5292 a MemoryError rather than silently stop the iteration.
5293
Guido van Rossum59ce9012008-08-09 14:55:34 +00005294- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5295 to _sre.compile() will now be rejected. This should not affect anybody
5296 since the re.compile() function never generates invalid re-bytecode.
5297
Skip Montanaroa032bf42008-08-08 22:52:51 +00005298- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5299 upon first access it can be automatically initialized from the csv file if
5300 it wasn't initialized during instantiation.
5301
Brett Cannon3aa2a492008-08-06 22:28:09 +00005302- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5303 the reload() built-in has been removed.
5304
Brett Cannon7e30b672008-08-04 21:52:25 +00005305- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005306 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005317 asking for a specific length. This problem only affected files opened
5318 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005319

5344 file name rather than a ZipInfo instance, so files are extracted with
5345 mode 0600 rather than 000 under Unix.
5346
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005347- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5348 argument in python 2.5, this broke code that subclassed Popen to include its
5349 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5363 coverage of the lookup process for special methods. The disclaimers
5364 regarding lack of coverage of new-style classes have also been
5365 removed, since the coverage is now fairly reasonable.

5374-----------------
5375
Georg Brandl3e483f62008-07-16 22:57:41 +00005376- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5377 its methods now allow for items objects that can be converted to
5378 an integer using operator.index().
5379
Mark Dickinson64b7e502008-07-16 09:40:03 +00005380- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5381 produced a ValueError instead of giving the correct float.
5382
Eric Smitha5fa5a22008-07-16 00:11:49 +00005383- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5384 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5385
Mark Dickinson7103aa42008-07-15 19:08:33 +00005386- Issue #3008: the float type has a new instance method 'float.hex'
5387 and a new class method 'float.fromhex' to convert floating-point
5388 numbers to and from hexadecimal strings, respectively.
5389
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005390- Issue #2235: __hash__ is once again inherited by default. To allow
5391 collections.Hashable to remain meaningful in the presence of the

Nick Coghlanb028f502008-07-13 14:52:36 +00005397- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5398 the parent module cannot be found while performing an absolute import.
5399 This means that an incorrectly defined __package__ attribute will
5400 now only prevent relative imports in that module rather than causing
5401 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005415- Issue #3004: Minor change to slice.indices(): the start and stop
5416 arguments are now treated identically, making the behaviour easier
5417 to describe and understand. For example, slice(None, -10,
5418 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5419 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5420 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00005874 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005875

5923 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005936- Issue #1631171: Re-implement the 'warnings' module in C (the
5937 original Python code has been kept as backup). This will allow for
5938 using the 'warning's machinery in such places as the parser where
5939 use of pure Python code is not possible. Both the ``showarning()``
5940 and ``formatwarning()`` gain an optional 'line' argument which is
5941 not called by default for backwards-compatibility reasons. Setting
5942 ``warnings.showwarning()`` to an implementation that lacks support
5943 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006006- Issue #2550: The approach used by client/server code for obtaining
6007 ports to listen on in network-oriented tests has been refined in an
6008 effort to facilitate running multiple instances of the entire
6009 regression test suite in parallel without issue.
6010 test_support.bind_port() has been fixed such that it will always
6011 return a unique port -- which wasn't always the case with the
6012 previous implementation, especially if socket options had been set
6013 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6014 new implementation of bind_port() will actually raise an exception
6015 if it is passed an AF_INET/SOCK_STREAM socket with either the
6016 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6017 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6018 the socket it's been passed. This currently only applies to
6019 Windows. This option prevents any other sockets from binding to the
6020 host/port we've bound to, thus removing the possibility of the
6021 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6022 when a second SOCK_STREAM socket binds and accepts to a host/port
6023 that's already been bound by another socket. The optional preferred
6024 port parameter to bind_port() has been removed. Under no
6025 circumstances should tests be hard coding ports!
6026
6027 test_support.find_unused_port() has also been introduced, which will
6028 pass a temporary socket object to bind_port() in order to obtain an
6029 unused port. The temporary socket object is then closed and
6030 deleted, and the port is returned. This method should only be used
6031 for obtaining an unused port in order to pass to an external program
6032 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6033 a parameter to a server-oriented class that doesn't give you direct
6034 access to the underlying socket used.
6035
6036 Finally, test_support.HOST has been introduced, which should be used
6037 for the host argument of any relevant socket calls (i.e. bind and
6038 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006039
6040 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006041 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006042 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6043 test_asynchat and test_socket_ssl.
6044
Georg Brandl3ee81df2008-05-17 18:14:43 +00006045 It is now possible for multiple instances of the regression test
6046 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006325- Added the future_builtins module, which contains hex() and oct().
6326 These are the PEP 3127 version of these functions, designed to be
6327 compatible with the hex() and oct() builtins from Python 3.0. They
6328 differ slightly in their output formats from the existing, unchanged
6329 Python 2.6 builtins. The expected usage of the future_builtins
6330 module is:
6331 from future_builtins import hex, oct
6332
Eric Smith7ef40bf2008-02-20 23:34:22 +00006333- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6334 exponents for exponents with absolute value < 100. Follows C99
6335 standard. This is a change on Windows, which would use 3 digits.
6336 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6337 so that any alterations it does to the resulting string will be
6338 available in stringlib/formatter.h (for float.__format__).
6339
Eric Smith5a3c1352008-02-19 13:21:56 +00006340- Implemented PEP 3101, Advanced String Formatting. This adds a new
6341 builtin format(); a format() method for str and unicode; a
6342 __format__() method to object, str, unicode, int, long, float, and
6343 datetime; the class string.Formatter; and the C API
6344 PyObject_Format().
6345
Georg Brandl3ee81df2008-05-17 18:14:43 +00006346- Fixed several potential crashes, all caused by specially crafted
6347 __del__ methods exploiting objects in temporarily inconsistent
6348 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006349
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006350- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006351 prevent a possible crash: an Abstract Base Class would try to access
6352 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006353
Georg Brandl3ee81df2008-05-17 18:14:43 +00006354- Fixed repr() and str() of complex numbers with infinity or nan as

Georg Brandl3ee81df2008-05-17 18:14:43 +00006357- Clear all free lists during a gc.collect() of the highest generation
6358 in order to allow pymalloc to free more arenas. Python may give back
6359 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006360
Georg Brandl3ee81df2008-05-17 18:14:43 +00006361- Issue #2045: Fix an infinite recursion triggered when printing a
6362 subclass of collections.defaultdict, if its default_factory is set
6363 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006364
Christian Heimesf75dbef2008-02-08 00:11:31 +00006365- Fixed a minor memory leak in dictobject.c. The content of the free
6366 list was not freed on interpreter shutdown.
6367
Georg Brandl21e99f42010-03-07 15:23:59 +00006368- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006369 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006370
Georg Brandl3ee81df2008-05-17 18:14:43 +00006371- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6372 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006373 to compact the internal free lists of pre-allocted ints and floats.
6374
Georg Brandl3ee81df2008-05-17 18:14:43 +00006375- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6376 calls. Python expected the return type int but the fork familie
6377 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006378
Georg Brandl3ee81df2008-05-17 18:14:43 +00006379- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6380 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006381
Georg Brandl3ee81df2008-05-17 18:14:43 +00006382- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6383 with the collections.Sequence API.

6389 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006390
Georg Brandl3ee81df2008-05-17 18:14:43 +00006391- Patch #1473257: generator objects gain a gi_code attribute. This is
6392 the same object as the func_code attribute of the function that
6393 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006394
Georg Brandl3ee81df2008-05-17 18:14:43 +00006395- Issue #1920: "while 0" statements were completely removed by the
6396 compiler, even in the presence of an "else" clause, which is
6397 supposed to be run when the condition is false. Now the compiler
6398 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006399
Guido van Rossumeead05f2008-01-24 18:21:02 +00006400- A few crashers fixed: weakref_in_del.py (issue #1377858);
6401 loosing_dict_ref.py (issue #1303614, test67.py);
6402 borrowed_ref_[34].py (not in tracker).
6403
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006404- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006405 suppressed while an extension is loaded by calling SetErrorMode in
6406 dynload_win.c. The error is still reported properly.
6407
Georg Brandl3ee81df2008-05-17 18:14:43 +00006408- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006409 several extension methods and modules do not work without unicode
6410 support.
6411
Georg Brandl26543b12008-01-21 18:36:51 +00006412- Issue #1882: when compiling code from a string, encoding cookies in the
6413 second line of code were not always recognized correctly.
6414
Georg Brandl14404b62008-01-19 19:27:05 +00006415- Issue #1679: "0x" was taken as a valid integer literal.
6416
Georg Brandl6caad7d2008-01-26 14:19:22 +00006417- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006418 added.
6419
Christian Heimesc94e2b52008-01-14 04:13:37 +00006420- sys.float_info / PyFloat_GetInfo: The floating point information
6421 object was converted from a dict to a specialized structseq object.
6422
Georg Brandl3ee81df2008-05-17 18:14:43 +00006423- Patch #1816: Added sys.flags structseq. It exposes the status of
6424 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006425
Georg Brandl3ee81df2008-05-17 18:14:43 +00006426- Objects/structseq.c: Implemented new structseq representation. The
6427 patch makes structseqs (e.g. the return value of os.stat) more
6428 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006429
Georg Brandl3ee81df2008-05-17 18:14:43 +00006430- Patch #1700288: added a type attribute cache that caches method
6431 accesses, resulting in speedups in heavily object-oriented code.

6439 envvar and sys.dont_write_bytecode attribute. All these can be set
6440 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006441
Georg Brandl3ee81df2008-05-17 18:14:43 +00006442- Improve some exception messages when Windows fails to load an
6443 extension module. Now we get for example '%1 is not a valid Win32
6444 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006445

Christian Heimes0a8143f2007-12-18 23:22:54 +00006451- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006452 and INF. float("nan"), float("inf") and float("-inf") now work on
6453 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006454
Georg Brandl3ee81df2008-05-17 18:14:43 +00006455- Compiler now generates simpler and faster code for dictionary
6456 literals. The oparg for BUILD_MAP now indicates an estimated

Georg Brandl3ee81df2008-05-17 18:14:43 +00006506- Issue #1686386: Tuple's tp_repr did not take into account the
6507 possibility of having a self-referential tuple, which is possible
6508 from C code. Nor did object's tp_str consider that a type's tp_str
6509 could do something that could lead to an inifinite recursion.
6510 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6511 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006527 PyObject_Call() never calling back out to Python code to trigger
6528 recursion depth updates/checks. Required the creation of a static

6578
Guido van Rossum143b5642007-03-23 04:58:42 +00006579- Bug #1683368: The object.__init__() and object.__new__() methods are
6580 now stricter in rejecting excess arguments. The only time when
6581 either allows excess arguments is when it is not overridden and the
6582 other one is. For backwards compatibility, when both are
6583 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006584 warning later). Also, type.__init__() insists on the same signature
6585 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006587- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6588 object to complex using its __complex__() method before falling back
6589 to the __float__() method. Therefore, the functions in the cmath
6590 module now can operate on objects that define a __complex__()
6591 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006609- Bug #1678647: write a newline after printing an exception in any
6610 case, even when converting the value to a string failed.
6611
Georg Brandl871f1bc2007-03-12 13:17:36 +00006612- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006613 its argument, if it exists. If not, it will work like before. This
6614 allows customizing the output of dir() in the presence of a
6615 __getattr__().

6625 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006626
Georg Brandlaa2321b2007-03-07 00:40:28 +00006627- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006628 makes the filenames the warning module prints much more sensible
6629 when a PYTHONSTARTUP file is used.

6644
Georg Brandl3ee81df2008-05-17 18:14:43 +00006645- When printing an unraisable error, don't print exceptions. before

Georg Brandl4e933132006-09-06 20:05:58 +00006730- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Guido van Rossum8bc09652008-02-21 18:18:37 +00006789- Removed uses of dict.has_key() from distutils, and uses of

7213
Georg Brandl92a6bae2007-03-13 17:43:32 +00007214- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007215 are set for invalid interpolation sequences that would lead to
7216 errors on reading back those values.

7272 TestCase and TestSuite subclasses (not instances) are no longer
7273 accepted in TestSuite.addTest(). This should cause no

7275 -- the failure just occurred later, with a more cumbersome
7276 exception.

7560 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007561
Georg Brandl3ee81df2008-05-17 18:14:43 +00007562- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007563 that the SMTP.starttls() caller no longer needs to call ehlo()
7564 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007565 does not claim to support starttls. Adds the
7566 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7647 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Raymond Hettinger12e94202007-11-07 01:13:09 +00007650

Georg Brandl3ee81df2008-05-17 18:14:43 +00007665 time so that opening a database previously created with the DB_DUP
7666 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7667 opens. Specifically: dictionary assignment to a DB object will
7668 replace all values for a given key when the database allows

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007949- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007950 periodic threadstate and signal checking in tight loops. By
7951 default, this option is turned-off. It should only be enabled in
7952 debugged, performance critical applications.

8004
Georg Brandl3ee81df2008-05-17 18:14:43 +00008005- Unified naming convention for free lists and their limits. All free
8006 lists in Object/ are named ``free_list``, the counter ``numfree``
8007 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8008 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008009
Georg Brandl3ee81df2008-05-17 18:14:43 +00008010- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8011 to ``PyTuple_SetItem``, it can be used to populate a brand new
8012 frozenset; but it does not steal a reference to the added item.

8024
Georg Brandl3ee81df2008-05-17 18:14:43 +00008025- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8026 of w# format code incorrectly truncated the length to an int, even
8027 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8028 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008029

8051- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8052 outside of pystate.c and should not be necessary.
8053
Georg Brandl3ee81df2008-05-17 18:14:43 +00008054- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8055 absolute imports. In earlier versions they might have used relative
8056 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008057
Georg Brandl3ee81df2008-05-17 18:14:43 +00008058- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8059 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008060
Georg Brandl3ee81df2008-05-17 18:14:43 +00008061- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00008086- Removed the macfs module. It had been deprecated since Python 2.5.
8087 This lead to the deprecation of macostools.touched() as it relied
