181 int.__pow__. These overflow checks were causing int.__pow__ to produce

197 cleared by the garbage collector. This fixes a segfault when an instance
198 and its type get caught in a reference cycle, and the instance's
199 deallocator calls one of the methods on the type (e.g. when subclassing

261 Distutils-based packages with C extension modules may fail because
262 Apple has removed gcc-4.2, the version used to build python.org
263 64-bit/32-bit Pythons. If the user does not explicitly override
264 the default C compiler by setting the CC environment variable,
265 Distutils will now attempt to compile extension modules with clang
266 if gcc-4.2 is required but not found. Also as a convenience, if
267 the user does explicitly set CC, substitute its value as the default
268 compiler in the Distutils LDSHARED configuration variable for OS X.
269 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
270 SDK, neither of which are available in Xcode 4. This change does not
271 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700544- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
545 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
546 interpreter process. This could cause failures in non-Distutils subprocesses
547 and was unreliable since tests or user programs could modify the interpreter
548 environment after Distutils set it. Instead, have Distutils set the the
549 deployment target only in the environment of each build subprocess. It is
550 still possible to globally override the default by setting
551 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
552 greater or equal to the default value, the value with which the interpreter
553 was built.

583 the ticker doesn't have to wind down to zero from the old starting point
584 before the new interval takes effect. And if the user increases the
585 interval, it makes sure the new limit takes effect right away rather have an
586 early task switch before recognizing the new interval.

1531 This prevents user-created self-referencing ordered dictionaries from
1532 becoming permanently uncollectable GC garbage. The downside is that
1533 removing __del__ means that the internal doubly-linked list has to wait for
1534 GC collection rather than freeing memory immediately when the refcnt drops
1535 to zero.

1997 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

2010 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002355 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

2379
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002380- Issue #7301: Add environment variable $PYTHONWARNINGS.
2381
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002382- Issue #8329: Don't return the same lists from select.select when no fds are
2383 changed.
2384
Georg Brandlfee0f442010-05-22 21:26:21 +00002385- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002386 on 64-bit machines. The shift count for either left or right shift is
2387 permitted to be up to sys.maxsize.
2388
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002389- Ensure that tokenization of identifiers is not affected by locale.

2394
Georg Brandlfee0f442010-05-22 21:26:21 +00002395- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2396 with a non-empty format string. This is an effort to future-proof user
2397 code. If a derived class does not currently implement __format__ but later
2398 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002399 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002400 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002401
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002402- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002415- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002416 (SIGINT). If an error occurs while importing the site module, the error is

2432
Georg Brandlfee0f442010-05-22 21:26:21 +00002433- Issue #8257: The Decimal construct now accepts a float instance directly,
2434 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002435
2436 >>> Decimal(1.1)
2437 Decimal('1.100000000000000088817841970012523233890533447265625')
2438
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002439- collections.Counter() now supports a subtract() method.
2440
Georg Brandlfee0f442010-05-22 21:26:21 +00002441- The functools module now has a total_ordering() class decorator to simplify
2442 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00002450- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2451 InvalidOperation instead of returning False. (Comparisons involving a quiet
2452 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2453 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002454
Georg Brandlfee0f442010-05-22 21:26:21 +00002455- Issue #2531: Comparison operations between floats and Decimal instances now
2456 return a result based on the numeric values of the operands; previously they
2457 returned an arbitrary result based on the relative ordering of id(float) and
2458 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002459
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002460- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002461 argument `-` which tells it to read files to compile from stdin. Each line is
2462 read on demand and the named file is compiled immediately. (Original patch by
2463 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002468- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2469 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002470 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00002472- Comparisons using one of <, <=, >, >= between a complex instance and a
2473 Fractions instance now raise TypeError instead of returning True/False. This
2474 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2475 <=> complex, and complex <=> complex comparisons.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002530- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002531 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2532 log file to compute the next rollover time. If the log file does not exist,
2533 the current time is used as the basis for the computation.

Georg Brandlba83f822010-03-14 09:50:54 +00002543- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2544 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2545 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002574- Issue #8300: When passing a non-integer argument to struct.pack with any
2575 integer format code, struct.pack first attempts to convert the non-integer
2576 using its __index__ method. If that method is non-existent or raises
2577 TypeError it goes on to try the __int__ method, as described below.
2578
Georg Brandlba83f822010-03-14 09:50:54 +00002579- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2580 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2581 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002582 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2583 inconsistent: __int__ was used for some integer codes but not for others, and
2584 the set of integer codes for which it was used differed between native packing
2585 and standard packing.)

2838 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2839 returning NULL. The macro now returns a statically allocated empty string

Georg Brandlba83f822010-03-14 09:50:54 +00002893 file position when calling `truncate()`. It would previously change the file
2894 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002895 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2898 class used to represent files stored inside an archive. The new
2899 implementation is significantly faster and can be wrapped in a
2900 ``io.BufferedReader`` object for more speedups. It also solves an issue
2901 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2914 encoded string for them. This ensures that the upload and register commands
2915 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003186- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3187 decimal string that's guaranteed to round back to x under correct rounding
3188 (with round-half-to-even rounding mode). Previously it gave a string based on
3189 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3190 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3191 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003192
Georg Brandlba83f822010-03-14 09:50:54 +00003193- Issue #7117: On almost all platforms: float-to-string and string-to-float
3194 conversions within Python are now correctly rounded. Places these conversions
3195 occur include: str for floats and complex numbers; the float and complex
3196 constructors; old-style and new-style numeric formatting; serialization and
3197 deserialization of floats and complex numbers using marshal, pickle and json;
3198 parsing of float and imaginary literals in Python code; Decimal-to-float
3199 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003200
Georg Brandlba83f822010-03-14 09:50:54 +00003201 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3202 providing correctly-rounded strtod and dtoa C functions. This code is
3203 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3204 the C compiler. There may be a small number of platforms on which correct
3205 operation of this code cannot be guaranteed, so the code is not used: notably,
3206 this applies to platforms where the C double format is not IEEE 754 binary64,
3207 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3208 and Python's configure script is unable to determine how to change the FPU
3209 precision. On these platforms conversions use the platform strtod and dtoa,
3210 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003212- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3213 uses the correctly-rounded string <-> float conversions described above (when
3214 available), and so produces correctly rounded results that will display nicely
3215 under the float repr. There are two related small changes: (1) round now
3216 accepts any class with an ``__index__()`` method for its second argument (but
3217 no longer accepts floats for the second argument), and (2) an excessively
3218 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3219 raises an exception.

3368 but with at least one decimal point and with a default precision
3369 of 12. Previously, the behavior the same but with a default precision of 6.
3370 This more closely matches ``str()``, and reduces surprises when adding

3484
Benjamin Peterson596d3062009-01-19 15:42:23 +00003485- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00003512- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3513 existing .py counterpart, override the co_filename attributes of all code
3514 objects if the original filename is obsolete (which can happen if the file has

3569
Georg Brandlba83f822010-03-14 09:50:54 +00003570- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3571 file objects with closefd=False. The file descriptor is still kept open but
3572 the file object behaves like a closed file. The ``FileIO`` object also got a
3573 new readonly attribute ``closefd``.

3592
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003593- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003596- On windows, ``os.chdir()`` given unicode was not working if
3597 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3598 this code path is really executed because I cannot move to such directory on
3599 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003601- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3602 element is temporarily replaced with an equivalent frozenset. But the
3603 eventual KeyError would always report the empty ``frozenset()`` as the missing
3604 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003624- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3625 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3626 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3627 of using the replace error handler in PyUnicode_DecodeUTF8().
3628
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003629- Issue #3739: The unicode-internal encoder now reports the number of characters

3631
Georg Brandlba83f822010-03-14 09:50:54 +00003632- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3634 gives improved memory leak detection when running under Valgrind, while taking
3635 advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00003707 __main__.py file. This allows applications that run other Python scripts to
3708 support the same flexibility as the CPython command line itself.

5001
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005002- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5003 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5004 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5005 ``printf`` function, whereas PyString_FromFormat has an independent
5006 implementation and uses "%zd" on all platforms for size_t values.
5007 This makes a difference on win64, where ``printf`` needs "%Id" to display
5008 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005010- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5014 object; previously an int would be returned for small values. the __long__
5015 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005025 was correctly parsed but parsing of subsequent arguments failed.
5026
Vinay Sajip35e3b032008-09-01 14:33:59 +00005027- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005028 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5029 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5030 when given a tuple of classes as second argument, were looking up
5031 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5032 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005103 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5104 for catch_warnings() also led to an improvement in the raising of a
5105 DeprecationWarning related to warnings.warn_explicit().
5106
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005107- The deprecation warnings for the old camelCase threading API were removed.
5108

5110
Christian Heimesa27a62e2008-08-22 19:55:54 +00005111- Silenced a trivial compiler warning in the sqlite module.
5112
Christian Heimes1cc69632008-08-22 20:10:27 +00005113- Fixed two format strings in the _collections module.
5114

5128 _check_logger_class from multiprocessing.
5129
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005130- Issue #2975: When compiling several extension modules with Visual Studio 2008
5131 from the same python interpreter, some environment variables would grow
5132 without limit.
5133
Benjamin Peterson37346b22008-08-23 20:27:43 +00005134- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5135 exploitation of poor argument checking.
5136
Gerhard Häringef2276b2008-09-12 13:54:06 +00005137- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
5138
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00005139- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
5140 remaining ones have "pysqlite_" prefix.
5141
Gerhard Häringe6872eb2008-09-12 22:33:22 +00005142- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

5150 wrapper for warnings.catch_warnings() that makes it easier to check
5151 that expected warning messages are being reported.
5152
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00005153- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005171What's New in Python 2.6 beta 3?
5172================================
5173
Barry Warsaw07a4a382008-08-21 01:15:08 +00005174*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005175
5176Core and Builtins
5177-----------------
5178
Guido van Rossumf8402962008-08-20 15:01:50 +00005179- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5180 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5181 extensions do not automatically benefit from the class attribute
5182 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5183 to their tp_flags field if they care. This is a backwards
5184 compatibility feature; in 3.0, all types will use the cache by
5185 default.
5186
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005187- Keyword arguments can now follow starred arguments. (``f(a, *args,
5188 keyword=23)`` is now valid syntax.)
5189
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005190- ctypes function pointers that are COM methods have a boolean True
5191 value again.
5192
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005193- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5194 by denying s# to parse objects that have a releasebuffer procedure,
5195 and introducing s*.
5196
Georg Brandl1e13ea92008-08-11 09:07:59 +00005197- Issue #3537: Fix an assertion failure when an empty but presized dict
5198 object was stored in the freelist.
5199
Mark Dickinsonb6467572008-08-04 21:30:09 +00005200- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5201 ValueError consistently across platforms.
5202
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005203- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5204 (64bit Unix, for example), unichr() would truncate its argument and return
5205 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5206
Neal Norwitze7d8be82008-07-31 17:17:14 +00005207- Apply security patches from Apple.
5208
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005209- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5210 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5211
Antoine Pitrou92f82162008-07-25 22:22:08 +00005212- Issue #1819: function calls with several named parameters are now on
5213 average 35% faster (as measured by pybench).
5214
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005215- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5216 the python debugger steps into a class statement: the free variables (local
5217 variables defined in an outer scope) would be deleted from the outer scope.
5218
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005219- Issue #2620: Overflow checking when allocating or reallocating memory
5220 was not always being done properly in some python types and extension
5221 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5222 all been updated to perform better checks and places in the code that
5223 would previously leak memory on the error path when such an allocation
5224 failed have been fixed.
5225

5227-------
5228
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005229- Issue #3612: Added some missing basic types in ctypes.wintypes.
5230
Benjamin Petersone977ad42008-08-20 01:42:01 +00005231- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5232 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5233
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005234- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5235 version reported by these tools does not necessarily follow the python
5236 version numbering scheme, so the module is less strict when parsing it.
5237
Nick Coghlanf70385a2008-08-18 12:42:46 +00005238- Issue #2235: Added Py3k warnings for types which will become unhashable
5239 under the stricter __hash__ inheritance rules in 3.0. Several types
5240 which did not meet the rules for hash invariants and were already
5241 unhashable in 3.0 have now been explicitly flagged as unhashable in
5242 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5243 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5244
Brett Cannon88f801d2008-08-18 00:46:22 +00005245- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5246 imported into the module but exposed as part of the module's API.
5247
Brett Cannon7b96f072008-08-18 00:41:11 +00005248- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5249
Brett Cannon46225e72008-08-18 00:36:52 +00005250- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005252- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5253
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005254- Issue #3575: Incremental decoder's decode function now takes bytearray
5255 by using 's*' instead of 't#'.
5256
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005257- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005258 fails unicode conversion on 2nd parameter. (windows only)
5259
Georg Brandl222e2082010-08-01 22:27:39 +00005260- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005261 in a redirect.
5262
Brett Cannonabe423e2008-08-16 21:47:07 +00005263- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005264 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005265
Facundo Batistaeb90b782008-08-16 14:44:07 +00005266- Issue #2776: fixed small issue when handling an URL with double slash
5267 after a 302 response in the case of not going through a proxy.
5268
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005269- Issue #2676: in the email package, content-type parsing was hanging on
5270 pathological input because of quadratic or exponential behaviour of a
5271 regular expression.
5272
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005273- Issue #3476: binary buffered reading through the new "io" library is now
5274 thread-safe.
5275
Brett Cannonbf3157b2008-08-14 05:00:03 +00005276- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5277 since mimetools itself is deprecated. Because modules are cached, all
5278 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5279
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005280- Issue #3134: shutil referenced undefined WindowsError symbol.
5281
Robert Schuppenies14646332008-08-10 11:01:53 +00005282- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5283 menu entries were not deleted.
5284
Brett Cannon83e81842008-08-09 23:30:55 +00005285- Copied the implementation of reduce() to _functools.reduce() to have a
5286 version that did not raise a DeprecationWarning under -3.
5287
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005288- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5289 a MemoryError rather than silently stop the iteration.
5290
Guido van Rossum59ce9012008-08-09 14:55:34 +00005291- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5292 to _sre.compile() will now be rejected. This should not affect anybody
5293 since the re.compile() function never generates invalid re-bytecode.
5294
Skip Montanaroa032bf42008-08-08 22:52:51 +00005295- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5296 upon first access it can be automatically initialized from the csv file if
5297 it wasn't initialized during instantiation.
5298
Brett Cannon3aa2a492008-08-06 22:28:09 +00005299- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5300 the reload() built-in has been removed.
5301
Brett Cannon7e30b672008-08-04 21:52:25 +00005302- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005303 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005314 asking for a specific length. This problem only affected files opened
5315 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005316

5341 file name rather than a ZipInfo instance, so files are extracted with
5342 mode 0600 rather than 000 under Unix.
5343
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005344- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5345 argument in python 2.5, this broke code that subclassed Popen to include its
5346 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5361 regarding lack of coverage of new-style classes have also been
5362 removed, since the coverage is now fairly reasonable.

5371-----------------
5372
Georg Brandl3e483f62008-07-16 22:57:41 +00005373- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5374 its methods now allow for items objects that can be converted to
5375 an integer using operator.index().
5376
Mark Dickinson64b7e502008-07-16 09:40:03 +00005377- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5378 produced a ValueError instead of giving the correct float.
5379
Eric Smitha5fa5a22008-07-16 00:11:49 +00005380- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5381 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5382
Mark Dickinson7103aa42008-07-15 19:08:33 +00005383- Issue #3008: the float type has a new instance method 'float.hex'
5384 and a new class method 'float.fromhex' to convert floating-point
5385 numbers to and from hexadecimal strings, respectively.
5386
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005387- Issue #2235: __hash__ is once again inherited by default. To allow
5388 collections.Hashable to remain meaningful in the presence of the

Nick Coghlanb028f502008-07-13 14:52:36 +00005394- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5395 the parent module cannot be found while performing an absolute import.
5396 This means that an incorrectly defined __package__ attribute will
5397 now only prevent relative imports in that module rather than causing
5398 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005412- Issue #3004: Minor change to slice.indices(): the start and stop
5413 arguments are now treated identically, making the behaviour easier
5414 to describe and understand. For example, slice(None, -10,
5415 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5416 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5417 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00005871 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005872

5920 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005933- Issue #1631171: Re-implement the 'warnings' module in C (the
5934 original Python code has been kept as backup). This will allow for
5935 using the 'warning's machinery in such places as the parser where
5936 use of pure Python code is not possible. Both the ``showarning()``
5937 and ``formatwarning()`` gain an optional 'line' argument which is
5938 not called by default for backwards-compatibility reasons. Setting
5939 ``warnings.showwarning()`` to an implementation that lacks support
5940 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006003- Issue #2550: The approach used by client/server code for obtaining
6004 ports to listen on in network-oriented tests has been refined in an
6005 effort to facilitate running multiple instances of the entire
6006 regression test suite in parallel without issue.
6007 test_support.bind_port() has been fixed such that it will always
6008 return a unique port -- which wasn't always the case with the
6009 previous implementation, especially if socket options had been set
6010 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6011 new implementation of bind_port() will actually raise an exception
6012 if it is passed an AF_INET/SOCK_STREAM socket with either the
6013 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6014 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6015 the socket it's been passed. This currently only applies to
6016 Windows. This option prevents any other sockets from binding to the
6017 host/port we've bound to, thus removing the possibility of the
6018 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6019 when a second SOCK_STREAM socket binds and accepts to a host/port
6020 that's already been bound by another socket. The optional preferred
6021 port parameter to bind_port() has been removed. Under no
6022 circumstances should tests be hard coding ports!
6023
6024 test_support.find_unused_port() has also been introduced, which will
6025 pass a temporary socket object to bind_port() in order to obtain an
6026 unused port. The temporary socket object is then closed and
6027 deleted, and the port is returned. This method should only be used
6028 for obtaining an unused port in order to pass to an external program
6029 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6030 a parameter to a server-oriented class that doesn't give you direct
6031 access to the underlying socket used.
6032
6033 Finally, test_support.HOST has been introduced, which should be used
6034 for the host argument of any relevant socket calls (i.e. bind and
6035 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006036
6037 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006038 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006039 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6040 test_asynchat and test_socket_ssl.
6041
Georg Brandl3ee81df2008-05-17 18:14:43 +00006042 It is now possible for multiple instances of the regression test
6043 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006322- Added the future_builtins module, which contains hex() and oct().
6323 These are the PEP 3127 version of these functions, designed to be
6324 compatible with the hex() and oct() builtins from Python 3.0. They
6325 differ slightly in their output formats from the existing, unchanged
6326 Python 2.6 builtins. The expected usage of the future_builtins
6327 module is:
6328 from future_builtins import hex, oct
6329
Eric Smith7ef40bf2008-02-20 23:34:22 +00006330- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6331 exponents for exponents with absolute value < 100. Follows C99
6332 standard. This is a change on Windows, which would use 3 digits.
6333 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6334 so that any alterations it does to the resulting string will be
6335 available in stringlib/formatter.h (for float.__format__).
6336
Eric Smith5a3c1352008-02-19 13:21:56 +00006337- Implemented PEP 3101, Advanced String Formatting. This adds a new
6338 builtin format(); a format() method for str and unicode; a
6339 __format__() method to object, str, unicode, int, long, float, and
6340 datetime; the class string.Formatter; and the C API
6341 PyObject_Format().
6342
Georg Brandl3ee81df2008-05-17 18:14:43 +00006343- Fixed several potential crashes, all caused by specially crafted
6344 __del__ methods exploiting objects in temporarily inconsistent
6345 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006346
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006347- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006348 prevent a possible crash: an Abstract Base Class would try to access
6349 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006350

Georg Brandl3ee81df2008-05-17 18:14:43 +00006354- Clear all free lists during a gc.collect() of the highest generation
6355 in order to allow pymalloc to free more arenas. Python may give back
6356 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006357
Georg Brandl3ee81df2008-05-17 18:14:43 +00006358- Issue #2045: Fix an infinite recursion triggered when printing a
6359 subclass of collections.defaultdict, if its default_factory is set
6360 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006361
Christian Heimesf75dbef2008-02-08 00:11:31 +00006362- Fixed a minor memory leak in dictobject.c. The content of the free
6363 list was not freed on interpreter shutdown.
6364
Georg Brandl21e99f42010-03-07 15:23:59 +00006365- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006367
Georg Brandl3ee81df2008-05-17 18:14:43 +00006368- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6369 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006370 to compact the internal free lists of pre-allocted ints and floats.
6371
Georg Brandl3ee81df2008-05-17 18:14:43 +00006372- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6373 calls. Python expected the return type int but the fork familie
6374 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006375
Georg Brandl3ee81df2008-05-17 18:14:43 +00006376- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6377 appear in the same code unit.

6386 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006387
Georg Brandl3ee81df2008-05-17 18:14:43 +00006388- Patch #1473257: generator objects gain a gi_code attribute. This is
6389 the same object as the func_code attribute of the function that
6390 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006391
Georg Brandl3ee81df2008-05-17 18:14:43 +00006392- Issue #1920: "while 0" statements were completely removed by the
6393 compiler, even in the presence of an "else" clause, which is
6394 supposed to be run when the condition is false. Now the compiler
6395 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006396
Guido van Rossumeead05f2008-01-24 18:21:02 +00006397- A few crashers fixed: weakref_in_del.py (issue #1377858);
6398 loosing_dict_ref.py (issue #1303614, test67.py);
6399 borrowed_ref_[34].py (not in tracker).
6400
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006401- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006402 suppressed while an extension is loaded by calling SetErrorMode in
6403 dynload_win.c. The error is still reported properly.
6404
Georg Brandl3ee81df2008-05-17 18:14:43 +00006405- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006406 several extension methods and modules do not work without unicode
6407 support.
6408
Georg Brandl26543b12008-01-21 18:36:51 +00006409- Issue #1882: when compiling code from a string, encoding cookies in the
6410 second line of code were not always recognized correctly.
6411
Georg Brandl14404b62008-01-19 19:27:05 +00006412- Issue #1679: "0x" was taken as a valid integer literal.
6413
Georg Brandl6caad7d2008-01-26 14:19:22 +00006414- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006415 added.
6416
Christian Heimesc94e2b52008-01-14 04:13:37 +00006417- sys.float_info / PyFloat_GetInfo: The floating point information
6418 object was converted from a dict to a specialized structseq object.
6419
Georg Brandl3ee81df2008-05-17 18:14:43 +00006420- Patch #1816: Added sys.flags structseq. It exposes the status of
6421 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006422
Georg Brandl3ee81df2008-05-17 18:14:43 +00006423- Objects/structseq.c: Implemented new structseq representation. The
6424 patch makes structseqs (e.g. the return value of os.stat) more
6425 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006426
Georg Brandl3ee81df2008-05-17 18:14:43 +00006427- Patch #1700288: added a type attribute cache that caches method
6428 accesses, resulting in speedups in heavily object-oriented code.

6436 envvar and sys.dont_write_bytecode attribute. All these can be set
6437 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006438
Georg Brandl3ee81df2008-05-17 18:14:43 +00006439- Improve some exception messages when Windows fails to load an
6440 extension module. Now we get for example '%1 is not a valid Win32
6441 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006442

Christian Heimes0a8143f2007-12-18 23:22:54 +00006448- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006449 and INF. float("nan"), float("inf") and float("-inf") now work on
6450 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006451
Georg Brandl3ee81df2008-05-17 18:14:43 +00006452- Compiler now generates simpler and faster code for dictionary
6453 literals. The oparg for BUILD_MAP now indicates an estimated

Georg Brandl3ee81df2008-05-17 18:14:43 +00006503- Issue #1686386: Tuple's tp_repr did not take into account the
6504 possibility of having a self-referential tuple, which is possible
6505 from C code. Nor did object's tp_str consider that a type's tp_str
6506 could do something that could lead to an inifinite recursion.
6507 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6508 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006524 PyObject_Call() never calling back out to Python code to trigger
6525 recursion depth updates/checks. Required the creation of a static

6575
Guido van Rossum143b5642007-03-23 04:58:42 +00006576- Bug #1683368: The object.__init__() and object.__new__() methods are
6577 now stricter in rejecting excess arguments. The only time when
6578 either allows excess arguments is when it is not overridden and the
6579 other one is. For backwards compatibility, when both are
6580 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006581 warning later). Also, type.__init__() insists on the same signature
6582 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006584- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6585 object to complex using its __complex__() method before falling back
6586 to the __float__() method. Therefore, the functions in the cmath
6587 module now can operate on objects that define a __complex__()
6588 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006606- Bug #1678647: write a newline after printing an exception in any
6607 case, even when converting the value to a string failed.
6608
Georg Brandl871f1bc2007-03-12 13:17:36 +00006609- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006610 its argument, if it exists. If not, it will work like before. This
6611 allows customizing the output of dir() in the presence of a
6612 __getattr__().

6622 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00006624- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006625 makes the filenames the warning module prints much more sensible
6626 when a PYTHONSTARTUP file is used.

6641
Georg Brandl3ee81df2008-05-17 18:14:43 +00006642- When printing an unraisable error, don't print exceptions. before

7210
Georg Brandl92a6bae2007-03-13 17:43:32 +00007211- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007212 are set for invalid interpolation sequences that would lead to
7213 errors on reading back those values.

7269 TestCase and TestSuite subclasses (not instances) are no longer
7270 accepted in TestSuite.addTest(). This should cause no

7272 -- the failure just occurred later, with a more cumbersome
7273 exception.

7557 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007558
Georg Brandl3ee81df2008-05-17 18:14:43 +00007559- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007560 that the SMTP.starttls() caller no longer needs to call ehlo()
7561 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007562 does not claim to support starttls. Adds the
7563 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00007647

Georg Brandl3ee81df2008-05-17 18:14:43 +00007662 time so that opening a database previously created with the DB_DUP
7663 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7664 opens. Specifically: dictionary assignment to a DB object will
7665 replace all values for a given key when the database allows

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007946- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007947 periodic threadstate and signal checking in tight loops. By
7948 default, this option is turned-off. It should only be enabled in
7949 debugged, performance critical applications.

8005 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008006
Georg Brandl3ee81df2008-05-17 18:14:43 +00008007- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8008 to ``PyTuple_SetItem``, it can be used to populate a brand new
8009 frozenset; but it does not steal a reference to the added item.

8021
Georg Brandl3ee81df2008-05-17 18:14:43 +00008022- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8023 of w# format code incorrectly truncated the length to an int, even
8024 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8025 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008026

Georg Brandl3ee81df2008-05-17 18:14:43 +00008055- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8056 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008057
Georg Brandl3ee81df2008-05-17 18:14:43 +00008058- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
