Raymond Hettinger20397532010-09-12 02:11:45 +0000601- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
602 This prevents user-created self-referencing ordered dictionaries from
603 becoming permanently uncollectable GC garbage. The downside is that
604 removing __del__ means that the internal doubly-linked list has to wait for
605 GC collection rather than freeing memory immediately when the refcnt drops
606 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001065- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1066 start byte and the continuation byte(s) are now considered invalid, instead
1067 of the number of bytes specified by the start byte.
1068 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1069 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1070 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001079- Issue #8748: Fix two issues with comparisons between complex and integer
1080 objects. (1) The comparison could incorrectly return True in some cases
1081 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1082 (2) The comparison raised an OverflowError for large integers, leading
1083 to unpredictable exceptions when combining integers and complex objects

1224 non-float non-integer argument is now converted to an integer (if possible)
1225 using its __int__ method. Previously, only small arguments were treated this

1278 operation raises multiple signals and more than one of those signals is
1279 trapped, the specification determines the order in which the signals should be
1280 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00001425- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001426 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1427 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1428 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1448Core and Builtins
1449-----------------
1450
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001451- Issue #7301: Add environment variable $PYTHONWARNINGS.
1452
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001453- Issue #8329: Don't return the same lists from select.select when no fds are
1454 changed.
1455
Georg Brandlfee0f442010-05-22 21:26:21 +00001456- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001457 on 64-bit machines. The shift count for either left or right shift is
1458 permitted to be up to sys.maxsize.
1459
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001460- Ensure that tokenization of identifiers is not affected by locale.
1461
Georg Brandlfee0f442010-05-22 21:26:21 +00001462- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001463
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001464- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1465
Georg Brandlfee0f442010-05-22 21:26:21 +00001466- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1467 with a non-empty format string. This is an effort to future-proof user
1468 code. If a derived class does not currently implement __format__ but later
1469 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001470 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001471 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001472
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001473- Issue #8268: Old-style classes (not just instances) now support weak
1474 references.
1475
Georg Brandlfee0f442010-05-22 21:26:21 +00001476- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
1477 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00001478
Victor Stinnerc7790ed2010-03-22 12:36:28 +00001479- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00001481- Issue #6474: Make error message from passing an inadequate number of keyword
1482 arguments to a function correct.
1483
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001484- Issue #8164: Don't allow lambda functions to have a docstring.
1485
Victor Stinner66644262010-03-10 22:30:19 +00001486- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001487 (SIGINT). If an error occurs while importing the site module, the error is
1488 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001489 module.

R. David Murray661303f2010-04-13 20:57:40 +00001496- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
1497
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001498- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001499 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1500 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00001502- Issue #8310: Allow dis to examine new style classes.
1503
Georg Brandlfee0f442010-05-22 21:26:21 +00001504- Issue #8257: The Decimal construct now accepts a float instance directly,
1505 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001506
1507 >>> Decimal(1.1)
1508 Decimal('1.100000000000000088817841970012523233890533447265625')
1509
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001510- collections.Counter() now supports a subtract() method.
1511
Georg Brandlfee0f442010-05-22 21:26:21 +00001512- The functools module now has a total_ordering() class decorator to simplify
1513 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001514
Georg Brandlfee0f442010-05-22 21:26:21 +00001515- The functools module also adds cmp_to_key() as a tool to transition old-style
1516 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001517
Georg Brandlfee0f442010-05-22 21:26:21 +00001518- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1519 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001520
Georg Brandlfee0f442010-05-22 21:26:21 +00001521- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1522 InvalidOperation instead of returning False. (Comparisons involving a quiet
1523 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1524 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001525
Georg Brandlfee0f442010-05-22 21:26:21 +00001526- Issue #2531: Comparison operations between floats and Decimal instances now
1527 return a result based on the numeric values of the operands; previously they
1528 returned an arbitrary result based on the relative ordering of id(float) and
1529 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001530
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001531- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001532 argument `-` which tells it to read files to compile from stdin. Each line is
1533 read on demand and the named file is compiled immediately. (Original patch by
1534 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001535
Georg Brandlfee0f442010-05-22 21:26:21 +00001536- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1537 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001539- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1540 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001541 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001542
Georg Brandlfee0f442010-05-22 21:26:21 +00001543- Comparisons using one of <, <=, >, >= between a complex instance and a
1544 Fractions instance now raise TypeError instead of returning True/False. This
1545 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1546 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001547
Michael Foorde6410c52010-03-29 20:04:23 +00001548- Addition of ``WeakSet`` to the ``weakref`` module.

1556
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001557- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001558 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1559 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001560
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001561- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1562 deprecated.
1563
Georg Brandlfee0f442010-05-22 21:26:21 +00001564- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1565 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001566

1571 existing at the same time, causing a Unicode error when configuration code
1572 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001573
Georg Brandlfee0f442010-05-22 21:26:21 +00001574- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
1575 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00001576
Antoine Pitroueee91cd2010-03-26 19:27:16 +00001577- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
1578 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1579 reads and writes are always retried by OpenSSL itself.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001601- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001602 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1603 log file to compute the next rollover time. If the log file does not exist,
1604 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001605

Georg Brandlba83f822010-03-14 09:50:54 +00001614- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1615 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1616 This is a behavior change, so email's minor version number is now bumped, to
1617 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001645- Issue #8300: When passing a non-integer argument to struct.pack with any
1646 integer format code, struct.pack first attempts to convert the non-integer
1647 using its __index__ method. If that method is non-existent or raises
1648 TypeError it goes on to try the __int__ method, as described below.
1649
Georg Brandlba83f822010-03-14 09:50:54 +00001650- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1651 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1652 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001653 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1654 inconsistent: __int__ was used for some integer codes but not for others, and
1655 the set of integer codes for which it was used differed between native packing
1656 and standard packing.)

2062
Georg Brandlba83f822010-03-14 09:50:54 +00002063- The ``__complex__()`` method is now looked up on the class of instances to

2068
Mark Dickinson1b34d252010-01-01 17:27:30 +00002069- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002070 DeprecationWarning when passed a float argument where an integer was expected.
2071 These functions and methods now raise TypeError instead. The majority of the
2072 effects of this change are in the extension modules, but some core functions
2073 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2074 and many unicode/str methods.

2089 least on IEEE 754 platforms), and in particular does not depend on the
2090 internal representation of a long.

2098
Georg Brandlba83f822010-03-14 09:50:54 +00002099 These executables now work properly with the arch(1) command: ``arch -ppc
2100 python`` will start a universal binary version of python in PPC mode (unlike

2240 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2241 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002242
Georg Brandlba83f822010-03-14 09:50:54 +00002243- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2244 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002245
Georg Brandlba83f822010-03-14 09:50:54 +00002246- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2247 1e-100 used to raise OverflowError, but now gives the requested 120
2248 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002256
Georg Brandlba83f822010-03-14 09:50:54 +00002257- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2258 decimal string that's guaranteed to round back to x under correct rounding
2259 (with round-half-to-even rounding mode). Previously it gave a string based on
2260 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2261 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2262 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002263
Georg Brandlba83f822010-03-14 09:50:54 +00002264- Issue #7117: On almost all platforms: float-to-string and string-to-float
2265 conversions within Python are now correctly rounded. Places these conversions
2266 occur include: str for floats and complex numbers; the float and complex
2267 constructors; old-style and new-style numeric formatting; serialization and
2268 deserialization of floats and complex numbers using marshal, pickle and json;
2269 parsing of float and imaginary literals in Python code; Decimal-to-float
2270 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002271
Georg Brandlba83f822010-03-14 09:50:54 +00002272 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2273 providing correctly-rounded strtod and dtoa C functions. This code is
2274 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2275 the C compiler. There may be a small number of platforms on which correct
2276 operation of this code cannot be guaranteed, so the code is not used: notably,
2277 this applies to platforms where the C double format is not IEEE 754 binary64,
2278 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2279 and Python's configure script is unable to determine how to change the FPU
2280 precision. On these platforms conversions use the platform strtod and dtoa,
2281 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002282
Georg Brandlba83f822010-03-14 09:50:54 +00002283- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2284 uses the correctly-rounded string <-> float conversions described above (when
2285 available), and so produces correctly rounded results that will display nicely
2286 under the float repr. There are two related small changes: (1) round now
2287 accepts any class with an ``__index__()`` method for its second argument (but
2288 no longer accepts floats for the second argument), and (2) an excessively
2289 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2290 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002294- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002432
Georg Brandlba83f822010-03-14 09:50:54 +00002433 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2434 (2) parsing of strings representing infinities and nans was locale aware; and
2435 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002437- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2438 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2439 but with at least one decimal point and with a default precision
2440 of 12. Previously, the behavior the same but with a default precision of 6.
2441 This more closely matches ``str()``, and reduces surprises when adding
2442 alignment flags to the empty presentation type. This also affects the new
2443 complex.__format__ in the same way.
2444
2445- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2446 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00002508 untrackable objects are not tracked by the garbage collector. This can reduce

2517 internal representation of integers, for performance reasons. Base 2**30 is
2518 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00002667- On windows, ``os.chdir()`` given unicode was not working if

2669 this code path is really executed because I cannot move to such directory on

2696 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2697 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2698 of using the replace error handler in PyUnicode_DecodeUTF8().
2699
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002700- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002703- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2705 gives improved memory leak detection when running under Valgrind, while taking
2706 advantage of pymalloc at other times.

4072
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004073- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4074 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4075 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4076 ``printf`` function, whereas PyString_FromFormat has an independent
4077 implementation and uses "%zd" on all platforms for size_t values.
4078 This makes a difference on win64, where ``printf`` needs "%Id" to display
4079 64bit values.

4085 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004096 was correctly parsed but parsing of subsequent arguments failed.
4097
Vinay Sajip35e3b032008-09-01 14:33:59 +00004098- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004099 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4100 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4101 when given a tuple of classes as second argument, were looking up
4102 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4103 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00004250- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4251 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4252 extensions do not automatically benefit from the class attribute
4253 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4254 to their tp_flags field if they care. This is a backwards
4255 compatibility feature; in 3.0, all types will use the cache by
4256 default.

Benjamin Petersonf647dc12008-08-20 01:27:30 +00004258- Keyword arguments can now follow starred arguments. (``f(a, *args,
4259 keyword=23)`` is now valid syntax.)
4260
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004261- ctypes function pointers that are COM methods have a boolean True
4262 value again.
4263
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004264- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4265 by denying s# to parse objects that have a releasebuffer procedure,
4266 and introducing s*.
4267
Georg Brandl1e13ea92008-08-11 09:07:59 +00004268- Issue #3537: Fix an assertion failure when an empty but presized dict
4269 object was stored in the freelist.
4270
Mark Dickinsonb6467572008-08-04 21:30:09 +00004271- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4272 ValueError consistently across platforms.
4273
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004274- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4275 (64bit Unix, for example), unichr() would truncate its argument and return
4276 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4277
Neal Norwitze7d8be82008-07-31 17:17:14 +00004278- Apply security patches from Apple.
4279
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004280- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4281 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4282
Antoine Pitrou92f82162008-07-25 22:22:08 +00004283- Issue #1819: function calls with several named parameters are now on
4284 average 35% faster (as measured by pybench).
4285
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004286- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4287 the python debugger steps into a class statement: the free variables (local
4288 variables defined in an outer scope) would be deleted from the outer scope.
4289
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004290- Issue #2620: Overflow checking when allocating or reallocating memory
4291 was not always being done properly in some python types and extension
4292 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4293 all been updated to perform better checks and places in the code that
4294 would previously leak memory on the error path when such an allocation
4295 failed have been fixed.

4301
Benjamin Petersone977ad42008-08-20 01:42:01 +00004302- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4303 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4304
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004305- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4306 version reported by these tools does not necessarily follow the python
4307 version numbering scheme, so the module is less strict when parsing it.
4308
Nick Coghlanf70385a2008-08-18 12:42:46 +00004309- Issue #2235: Added Py3k warnings for types which will become unhashable
4310 under the stricter __hash__ inheritance rules in 3.0. Several types
4311 which did not meet the rules for hash invariants and were already
4312 unhashable in 3.0 have now been explicitly flagged as unhashable in
4313 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4314 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4315
Brett Cannon88f801d2008-08-18 00:46:22 +00004316- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4317 imported into the module but exposed as part of the module's API.
4318

4324
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004325- Issue #3575: Incremental decoder's decode function now takes bytearray
4326 by using 's*' instead of 't#'.
4327
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004328- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004329 fails unicode conversion on 2nd parameter. (windows only)

Brett Cannon721b1452008-08-16 22:00:27 +00004335 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004336
Facundo Batistaeb90b782008-08-16 14:44:07 +00004337- Issue #2776: fixed small issue when handling an URL with double slash
4338 after a 302 response in the case of not going through a proxy.
4339
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004340- Issue #2676: in the email package, content-type parsing was hanging on
4341 pathological input because of quadratic or exponential behaviour of a
4342 regular expression.
4343
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004344- Issue #3476: binary buffered reading through the new "io" library is now
4345 thread-safe.
4346
Brett Cannonbf3157b2008-08-14 05:00:03 +00004347- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4348 since mimetools itself is deprecated. Because modules are cached, all
4349 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4350
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004351- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00004353- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4354 menu entries were not deleted.
4355
Brett Cannon83e81842008-08-09 23:30:55 +00004356- Copied the implementation of reduce() to _functools.reduce() to have a
4357 version that did not raise a DeprecationWarning under -3.
4358
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004359- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4360 a MemoryError rather than silently stop the iteration.
4361
Guido van Rossum59ce9012008-08-09 14:55:34 +00004362- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4363 to _sre.compile() will now be rejected. This should not affect anybody
4364 since the re.compile() function never generates invalid re-bytecode.
4365
Skip Montanaroa032bf42008-08-08 22:52:51 +00004366- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4367 upon first access it can be automatically initialized from the csv file if
4368 it wasn't initialized during instantiation.
4369
Brett Cannon3aa2a492008-08-06 22:28:09 +00004370- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4371 the reload() built-in has been removed.
4372
Brett Cannon7e30b672008-08-04 21:52:25 +00004373- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004374 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4382 raised an AttributeError.
4383
Benjamin Peterson01a24322008-07-28 23:35:27 +00004384- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004385 asking for a specific length. This problem only affected files opened
4386 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004387

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004411- Issue #3394: zipfile.writestr sets external attributes when passed a
4412 file name rather than a ZipInfo instance, so files are extracted with
4413 mode 0600 rather than 000 under Unix.
4414
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004415- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4416 argument in python 2.5, this broke code that subclassed Popen to include its
4417 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004427- Issue #2235: the C API function PyObject_HashNotImplemented and its
4428 interaction with the tp_hash slot (added in 2.6b2) are now documented
4429
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004430- Issue #643841: The language reference now provides more detailed
4431 coverage of the lookup process for special methods. The disclaimers
4432 regarding lack of coverage of new-style classes have also been
4433 removed, since the coverage is now fairly reasonable.

4437================================
4438
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004439*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004441Core and Builtins
4442-----------------
4443
Georg Brandl3e483f62008-07-16 22:57:41 +00004444- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4445 its methods now allow for items objects that can be converted to
4446 an integer using operator.index().
4447
Mark Dickinson64b7e502008-07-16 09:40:03 +00004448- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4449 produced a ValueError instead of giving the correct float.
4450
Eric Smitha5fa5a22008-07-16 00:11:49 +00004451- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4452 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4453
Mark Dickinson7103aa42008-07-15 19:08:33 +00004454- Issue #3008: the float type has a new instance method 'float.hex'
4455 and a new class method 'float.fromhex' to convert floating-point
4456 numbers to and from hexadecimal strings, respectively.
4457
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004458- Issue #2235: __hash__ is once again inherited by default. To allow
4459 collections.Hashable to remain meaningful in the presence of the
4460 default hash implementation (object.__hash__), it is now possible
4461 to explicit block inheritance of hash by setting __hash__=None at
4462 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4463 level.
4464
Nick Coghlanb028f502008-07-13 14:52:36 +00004465- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4466 the parent module cannot be found while performing an absolute import.
4467 This means that an incorrectly defined __package__ attribute will
4468 now only prevent relative imports in that module rather than causing
4469 all imports from that module to fail.
4470
Nick Coghlan14ff9942008-07-08 14:21:42 +00004471- Issue #2517: Allow unicode messages in Exceptions again by correctly
4472 bypassing the instance dictionary when looking up __unicode__ on
4473 new-style classes.
4474
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004475- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4476 set to a custom object whose write() method happens to install
4477 another file in sys.stdout.
4478
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004479- Issue #3088: Corrected a race condition in classes derived from
4480 threading.local: the first member set by a thread could be saved in
4481 another thread's dictionary.
4482
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004483- Issue #3004: Minor change to slice.indices(): the start and stop
4484 arguments are now treated identically, making the behaviour easier
4485 to describe and understand. For example, slice(None, -10,
4486 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4487 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4488 10, -1).
4489
Georg Brandl278fc502008-07-19 12:46:12 +00004490- Issue #3219: Calling a function with repeated keyword arguments,
4491 f(a=2, a=23), would not cause a syntax error. This was a regression
4492 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004493
Georg Brandl278fc502008-07-19 12:46:12 +00004494- Issue #2862: Make int and float freelist management consistent with
4495 other freelists. Changes their CompactFreeList apis into
4496 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004497

4500
Thomas Heller57adf222008-08-14 19:10:48 +00004501- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4502 api functions without holding the GIL, which could lead to a fatal
4503 error when they failed.
4504
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004505- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4514 ForkingPickler.register() to resolve conflict with ctypes.
4515
Vinay Sajip51e65192008-07-18 09:01:10 +00004516- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004517
Thomas Heller880f5292008-07-15 19:39:38 +00004518- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4519 a valid dlerror() message.
4520
Thomas Heller2bad6572008-07-15 17:19:50 +00004521- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4522 incomplete structure was created.
4523
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004524- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00004526- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4527
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004528- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004529
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004530- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4531 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004532 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004533 content-length. The problem had been corrected in the 2.4 branch, but never
4534 merged into trunk.
4535
Georg Brandle78fbcc2008-07-05 10:13:36 +00004536- Issue #2663: add filtering capability to shutil.copytree().

4941 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004942 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004943
4944 This is controlled by the configure argument ``--with-universal-archs``:
4945
4946 - ``--with-universal-archs=all``: install 4-way universal
4947
4948 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4949
4950 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4951
4952 This option should be used in combination with ``--enable-universalsdk=``.
4953
4954 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00005004- Issue #1631171: Re-implement the 'warnings' module in C (the
5005 original Python code has been kept as backup). This will allow for
5006 using the 'warning's machinery in such places as the parser where
5007 use of pure Python code is not possible. Both the ``showarning()``
5008 and ``formatwarning()`` gain an optional 'line' argument which is
5009 not called by default for backwards-compatibility reasons. Setting
5010 ``warnings.showwarning()`` to an implementation that lacks support
5011 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005074- Issue #2550: The approach used by client/server code for obtaining
5075 ports to listen on in network-oriented tests has been refined in an
5076 effort to facilitate running multiple instances of the entire
5077 regression test suite in parallel without issue.
5078 test_support.bind_port() has been fixed such that it will always
5079 return a unique port -- which wasn't always the case with the
5080 previous implementation, especially if socket options had been set
5081 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5082 new implementation of bind_port() will actually raise an exception
5083 if it is passed an AF_INET/SOCK_STREAM socket with either the
5084 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5085 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5086 the socket it's been passed. This currently only applies to
5087 Windows. This option prevents any other sockets from binding to the
5088 host/port we've bound to, thus removing the possibility of the
5089 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5090 when a second SOCK_STREAM socket binds and accepts to a host/port
5091 that's already been bound by another socket. The optional preferred
5092 port parameter to bind_port() has been removed. Under no
5093 circumstances should tests be hard coding ports!
5094
5095 test_support.find_unused_port() has also been introduced, which will
5096 pass a temporary socket object to bind_port() in order to obtain an
5097 unused port. The temporary socket object is then closed and
5098 deleted, and the port is returned. This method should only be used
5099 for obtaining an unused port in order to pass to an external program
5100 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5101 a parameter to a server-oriented class that doesn't give you direct
5102 access to the underlying socket used.
5103
5104 Finally, test_support.HOST has been introduced, which should be used

5382
Fred Drakea8ee94b2008-03-01 02:45:07 +00005383- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005384 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005385
Georg Brandlad61bc82008-02-23 15:11:18 +00005386- Issue #2067: file.__exit__() now calls subclasses' close() method.
5387
5388- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005389
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005390- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005391 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005392
Eric Smitha73fbe72008-02-23 03:09:44 +00005393- Added the future_builtins module, which contains hex() and oct().
5394 These are the PEP 3127 version of these functions, designed to be
5395 compatible with the hex() and oct() builtins from Python 3.0. They
5396 differ slightly in their output formats from the existing, unchanged
5397 Python 2.6 builtins. The expected usage of the future_builtins
5398 module is:
5399 from future_builtins import hex, oct
5400
Eric Smith7ef40bf2008-02-20 23:34:22 +00005401- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5402 exponents for exponents with absolute value < 100. Follows C99
5403 standard. This is a change on Windows, which would use 3 digits.
5404 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5405 so that any alterations it does to the resulting string will be
5406 available in stringlib/formatter.h (for float.__format__).
5407
Eric Smith5a3c1352008-02-19 13:21:56 +00005408- Implemented PEP 3101, Advanced String Formatting. This adds a new
5409 builtin format(); a format() method for str and unicode; a
5410 __format__() method to object, str, unicode, int, long, float, and
5411 datetime; the class string.Formatter; and the C API
5412 PyObject_Format().
5413
Georg Brandl3ee81df2008-05-17 18:14:43 +00005414- Fixed several potential crashes, all caused by specially crafted
5415 __del__ methods exploiting objects in temporarily inconsistent
5416 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005417
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005418- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005419 prevent a possible crash: an Abstract Base Class would try to access
5420 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005421
Georg Brandl3ee81df2008-05-17 18:14:43 +00005422- Fixed repr() and str() of complex numbers with infinity or nan as
5423 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005424
Georg Brandl3ee81df2008-05-17 18:14:43 +00005425- Clear all free lists during a gc.collect() of the highest generation
5426 in order to allow pymalloc to free more arenas. Python may give back
5427 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005428
Georg Brandl3ee81df2008-05-17 18:14:43 +00005429- Issue #2045: Fix an infinite recursion triggered when printing a
5430 subclass of collections.defaultdict, if its default_factory is set
5431 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005432
Christian Heimesf75dbef2008-02-08 00:11:31 +00005433- Fixed a minor memory leak in dictobject.c. The content of the free
5434 list was not freed on interpreter shutdown.
5435
Georg Brandl21e99f42010-03-07 15:23:59 +00005436- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005437 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005438
Georg Brandl3ee81df2008-05-17 18:14:43 +00005439- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5440 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005441 to compact the internal free lists of pre-allocted ints and floats.
5442
Georg Brandl3ee81df2008-05-17 18:14:43 +00005443- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5444 calls. Python expected the return type int but the fork familie
5445 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005446
Georg Brandl3ee81df2008-05-17 18:14:43 +00005447- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5448 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005449
Georg Brandl3ee81df2008-05-17 18:14:43 +00005450- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5451 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005452
Georg Brandl3ee81df2008-05-17 18:14:43 +00005453- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5454 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005455
Georg Brandl3ee81df2008-05-17 18:14:43 +00005456- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5457 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005458
Georg Brandl3ee81df2008-05-17 18:14:43 +00005459- Patch #1473257: generator objects gain a gi_code attribute. This is
5460 the same object as the func_code attribute of the function that
5461 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005462
Georg Brandl3ee81df2008-05-17 18:14:43 +00005463- Issue #1920: "while 0" statements were completely removed by the
5464 compiler, even in the presence of an "else" clause, which is
5465 supposed to be run when the condition is false. Now the compiler
5466 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005467
Guido van Rossumeead05f2008-01-24 18:21:02 +00005468- A few crashers fixed: weakref_in_del.py (issue #1377858);
5469 loosing_dict_ref.py (issue #1303614, test67.py);
5470 borrowed_ref_[34].py (not in tracker).
5471
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005472- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005473 suppressed while an extension is loaded by calling SetErrorMode in
5474 dynload_win.c. The error is still reported properly.
5475
Georg Brandl3ee81df2008-05-17 18:14:43 +00005476- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005477 several extension methods and modules do not work without unicode
5478 support.
5479
Georg Brandl26543b12008-01-21 18:36:51 +00005480- Issue #1882: when compiling code from a string, encoding cookies in the
5481 second line of code were not always recognized correctly.
5482
Georg Brandl14404b62008-01-19 19:27:05 +00005483- Issue #1679: "0x" was taken as a valid integer literal.
5484
Georg Brandl6caad7d2008-01-26 14:19:22 +00005485- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005486 added.
5487
Christian Heimesc94e2b52008-01-14 04:13:37 +00005488- sys.float_info / PyFloat_GetInfo: The floating point information
5489 object was converted from a dict to a specialized structseq object.
5490
Georg Brandl3ee81df2008-05-17 18:14:43 +00005491- Patch #1816: Added sys.flags structseq. It exposes the status of
5492 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005493
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494- Objects/structseq.c: Implemented new structseq representation. The
5495 patch makes structseqs (e.g. the return value of os.stat) more
5496 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005497
Georg Brandl3ee81df2008-05-17 18:14:43 +00005498- Patch #1700288: added a type attribute cache that caches method
5499 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005500
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005501- Bug #1776: __import__() no longer accepts filenames on any platform.
5502 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005503
Georg Brandlaed6c662008-01-07 17:25:53 +00005504- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5505
Georg Brandl3ee81df2008-05-17 18:14:43 +00005506- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5507 envvar and sys.dont_write_bytecode attribute. All these can be set
5508 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005509
Georg Brandl3ee81df2008-05-17 18:14:43 +00005510- Improve some exception messages when Windows fails to load an
5511 extension module. Now we get for example '%1 is not a valid Win32
5512 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005513
Georg Brandl3ee81df2008-05-17 18:14:43 +00005514- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005516- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5517 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005518
Christian Heimes0a8143f2007-12-18 23:22:54 +00005519- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005520 and INF. float("nan"), float("inf") and float("-inf") now work on
5521 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005522
Georg Brandl3ee81df2008-05-17 18:14:43 +00005523- Compiler now generates simpler and faster code for dictionary
5524 literals. The oparg for BUILD_MAP now indicates an estimated
5525 dictionary size. There is a new opcode, STORE_MAP, for adding
5526 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005527
Georg Brandl3ee81df2008-05-17 18:14:43 +00005528- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005533- Issue #1538: Avoid copying string in split/rsplit if the split char
5534 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005535
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005536- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005537 SystemError.
5538
Nick Coghlanef01d822007-12-03 12:55:17 +00005539- PEP 366: Allow explicit relative imports when executing modules
5540 inside packages with the -m switch via a new module level
5541 __package__ attribute.
5542
Georg Brandl3ee81df2008-05-17 18:14:43 +00005543- Issue #1402: Fix a crash on exit, when another thread is still
5544 running, and if the deallocation of its frames somehow calls the
5545 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005546

Georg Brandl3ee81df2008-05-17 18:14:43 +00005560- Issue #1265: Fix a problem with sys.settrace, if the tracing
5561 function uses a generator expression when at the same time the
5562 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005563
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005564- sets and frozensets now have an isdisjoint() method.
5565
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005566- optimize the performance of builtin.sum().
5567
Neal Norwitz44f326e2007-10-05 05:29:17 +00005568- Fix warnings found by the new version of the Coverity checker.
5569
Georg Brandl21e99f42010-03-07 15:23:59 +00005570- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005571 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5572 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005573
Georg Brandl3ee81df2008-05-17 18:14:43 +00005574- Issue #1686386: Tuple's tp_repr did not take into account the
5575 possibility of having a self-referential tuple, which is possible
5576 from C code. Nor did object's tp_str consider that a type's tp_str
5577 could do something that could lead to an inifinite recursion.
5578 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5579 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005580
Georg Brandl3ee81df2008-05-17 18:14:43 +00005581- Issue #1164: It was possible to trigger deadlock when using the
5582 'print' statement to write to a file since the GIL was not released
5583 as needed. Now PyObject_Print() does the right thing along with
5584 various tp_print implementations of the built-in types and those in
5585 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005586
Georg Brandl3ee81df2008-05-17 18:14:43 +00005587- Issue #1147: Exceptions were directly allowing string exceptions in
5588 their throw() method even though string exceptions no longer
5589 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005590

Brett Cannon1e534b52007-09-07 04:18:30 +00005594- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005595 PyObject_Call() never calling back out to Python code to trigger
5596 recursion depth updates/checks. Required the creation of a static
5597 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005615 __*__ attributes. (Some already existed, e.g., __doc__ and
5616 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005617

Georg Brandl3ee81df2008-05-17 18:14:43 +00005625 "except E as target:". This is to provide forwards compatibility
5626 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005627
Brett Cannon229cee22007-05-05 01:34:02 +00005628- Deprecate BaseException.message as per PEP 352.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005634 setting a plain string, ie don't expand to single letter identifiers.
5635
Raymond Hettinger13936692007-04-11 18:40:58 +00005636- Request #1191699: Slices can now be pickled.

5646
Guido van Rossum143b5642007-03-23 04:58:42 +00005647- Bug #1683368: The object.__init__() and object.__new__() methods are
5648 now stricter in rejecting excess arguments. The only time when
5649 either allows excess arguments is when it is not overridden and the
5650 other one is. For backwards compatibility, when both are
5651 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005652 warning later). Also, type.__init__() insists on the same signature
5653 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005654
Georg Brandl3ee81df2008-05-17 18:14:43 +00005655- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5656 object to complex using its __complex__() method before falling back
5657 to the __float__() method. Therefore, the functions in the cmath
5658 module now can operate on objects that define a __complex__()
5659 method.

5676
Georg Brandl7b9c5552007-03-12 14:30:05 +00005677- Bug #1678647: write a newline after printing an exception in any
5678 case, even when converting the value to a string failed.
5679
Georg Brandl871f1bc2007-03-12 13:17:36 +00005680- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005681 its argument, if it exists. If not, it will work like before. This
5682 allows customizing the output of dir() in the presence of a
5683 __getattr__().

5693 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005694
Georg Brandlaa2321b2007-03-07 00:40:28 +00005695- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005696 makes the filenames the warning module prints much more sensible
5697 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005698

Georg Brandl0fca97a2007-03-05 22:28:08 +00005710- Patch #1674228: when assigning a slice (old-style), check for the
5711 sq_ass_slice instead of the sq_slice slot.
5712
Georg Brandl3ee81df2008-05-17 18:14:43 +00005713- When printing an unraisable error, don't print exceptions. before

6341 accepted in TestSuite.addTest(). This should cause no
6342 incompatibility since it never made sense with ordinary subclasses
6343 -- the failure just occurred later, with a more cumbersome
6344 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006625- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6626 with RFC 3207 and forgets any knowledge obtained from the server not
6627 obtained from the TLS negotiation itself. Patch contributed by Bill
6628 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006629
Georg Brandl3ee81df2008-05-17 18:14:43 +00006630- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006631 that the SMTP.starttls() caller no longer needs to call ehlo()
6632 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006633 does not claim to support starttls. Adds the
6634 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6715 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6716 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00006733 time so that opening a database previously created with the DB_DUP
6734 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6735 opens. Specifically: dictionary assignment to a DB object will
6736 replace all values for a given key when the database allows
6737 duplicate values. DB users should use DB.put(k, v) when they want
6738 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006739

6745 characters with ASCII value less than 32. Also, it correctly quotes
6746 dots only if they occur on a single line, as opposed to the previous
6747 behavior of quoting dots if they are the second character of any
6748 line.

Neal Norwitz92422fb2006-08-18 03:57:54 +00007070C API
7071-----
7072
Georg Brandl3ee81df2008-05-17 18:14:43 +00007073- Unified naming convention for free lists and their limits. All free
7074 lists in Object/ are named ``free_list``, the counter ``numfree``
7075 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7076 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007077
Georg Brandl3ee81df2008-05-17 18:14:43 +00007078- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7079 to ``PyTuple_SetItem``, it can be used to populate a brand new
7080 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007081
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007082- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007083
Georg Brandl3ee81df2008-05-17 18:14:43 +00007084- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7085 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7086 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007087
7088- Patch #1720595: add T_BOOL to the range of structmember types.
7089
7090- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7091 ``PyFloat_GetInfo()`` to the float API.
7092
Georg Brandl3ee81df2008-05-17 18:14:43 +00007093- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7094 of w# format code incorrectly truncated the length to an int, even
7095 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7096 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007097
Georg Brandl3ee81df2008-05-17 18:14:43 +00007098- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7099 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007100
Georg Brandl3ee81df2008-05-17 18:14:43 +00007101- PEP 3123: Provide forward compatibility with Python 3.0, while
7102 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7103 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007104
Georg Brandl3ee81df2008-05-17 18:14:43 +00007105- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7106 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007107
7108- Patch #1733960: Allow T_LONGLONG to accept ints.
7109
7110- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7111
Christian Heimes000a0742008-01-03 22:16:32 +00007112- Added a new API function ``PyImport_ImportModuleNoBlock``.
7113
Georg Brandl6caad7d2008-01-26 14:19:22 +00007114- Bug #1637022: Prefix AST symbols with _Py_.
7115
7116- Fix some leftovers from the conversion from int to Py_ssize_t
7117 (relevant to strings and sequences of more than 2**31 items).
7118
7119- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7120 outside of pystate.c and should not be necessary.
7121
Georg Brandl3ee81df2008-05-17 18:14:43 +00007122- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7123 absolute imports. In earlier versions they might have used relative
7124 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007125
Georg Brandl3ee81df2008-05-17 18:14:43 +00007126- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7127 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007128
Georg Brandl3ee81df2008-05-17 18:14:43 +00007129- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7130 macro so it can be used as an expression.

7135
Georg Brandl3ee81df2008-05-17 18:14:43 +00007136- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7137 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7138 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7139 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007140
Georg Brandl3ee81df2008-05-17 18:14:43 +00007141- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
7142 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007154- Removed the macfs module. It had been deprecated since Python 2.5.
7155 This lead to the deprecation of macostools.touched() as it relied
7156 solely on macfs and was a no-op under OS X.
