603
Raymond Hettinger20397532010-09-12 02:11:45 +0000604- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
605 This prevents user-created self-referencing ordered dictionaries from
606 becoming permanently uncollectable GC garbage. The downside is that
607 removing __del__ means that the internal doubly-linked list has to wait for
608 GC collection rather than freeing memory immediately when the refcnt drops
609 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001068- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1069 start byte and the continuation byte(s) are now considered invalid, instead
1070 of the number of bytes specified by the start byte.
1071 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1072 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1073 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

1083 objects. (1) The comparison could incorrectly return True in some cases
1084 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1085 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00001197- On darwin, ``test_site`` assumed that a framework build was being used,
1198 leading to a failure where four directories were expected for site-packages
1199 instead of two in a non-framework build.

Georg Brandlfee0f442010-05-22 21:26:21 +00001226- Issue #1533: Fix inconsistency in range function argument processing: any
1227 non-float non-integer argument is now converted to an integer (if possible)
1228 using its __int__ method. Previously, only small arguments were treated this
1229 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00001238 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00001239 benefit compared to the dynamic memory allocation fallback. Patch by

1265 messages when accessing undefined class attributes because of the cheap
1266 inheritance with the underlying socket object. The cheap inheritance has been
1267 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00001280- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1281 operation raises multiple signals and more than one of those signals is
1282 trapped, the specification determines the order in which the signals should be
1283 handled. In many cases this order wasn't being followed, leading to the wrong
1284 Python exception being raised.

Georg Brandlfee0f442010-05-22 21:26:21 +00001428- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001429 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1430 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1431 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00001450
1451Core and Builtins
1452-----------------
1453
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001454- Issue #7301: Add environment variable $PYTHONWARNINGS.
1455
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001456- Issue #8329: Don't return the same lists from select.select when no fds are
1457 changed.
1458
Georg Brandlfee0f442010-05-22 21:26:21 +00001459- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001460 on 64-bit machines. The shift count for either left or right shift is
1461 permitted to be up to sys.maxsize.
1462
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001463- Ensure that tokenization of identifiers is not affected by locale.
1464
Georg Brandlfee0f442010-05-22 21:26:21 +00001465- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001466
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001467- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1468
Georg Brandlfee0f442010-05-22 21:26:21 +00001469- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1470 with a non-empty format string. This is an effort to future-proof user
1471 code. If a derived class does not currently implement __format__ but later
1472 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001473 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001474 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001475
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001476- Issue #8268: Old-style classes (not just instances) now support weak
1477 references.
1478
Georg Brandlfee0f442010-05-22 21:26:21 +00001479- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
1480 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00001481
Victor Stinnerc7790ed2010-03-22 12:36:28 +00001482- Issue #1583863: An unicode subclass can now override the __unicode__ method

1485 arguments to a function correct.
1486
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001487- Issue #8164: Don't allow lambda functions to have a docstring.
1488
Victor Stinner66644262010-03-10 22:30:19 +00001489- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001490 (SIGINT). If an error occurs while importing the site module, the error is
1491 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001492 module.
1493
Collin Winter001a3952010-03-18 21:54:01 +00001494- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00001499- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
1500
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001501- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001502 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1503 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00001505- Issue #8310: Allow dis to examine new style classes.
1506
Georg Brandlfee0f442010-05-22 21:26:21 +00001507- Issue #8257: The Decimal construct now accepts a float instance directly,
1508 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001509
1510 >>> Decimal(1.1)
1511 Decimal('1.100000000000000088817841970012523233890533447265625')
1512
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001513- collections.Counter() now supports a subtract() method.
1514
Georg Brandlfee0f442010-05-22 21:26:21 +00001515- The functools module now has a total_ordering() class decorator to simplify
1516 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001517
Georg Brandlfee0f442010-05-22 21:26:21 +00001518- The functools module also adds cmp_to_key() as a tool to transition old-style
1519 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001520
Georg Brandlfee0f442010-05-22 21:26:21 +00001521- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1522 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001523
Georg Brandlfee0f442010-05-22 21:26:21 +00001524- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1525 InvalidOperation instead of returning False. (Comparisons involving a quiet
1526 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1527 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001528
Georg Brandlfee0f442010-05-22 21:26:21 +00001529- Issue #2531: Comparison operations between floats and Decimal instances now
1530 return a result based on the numeric values of the operands; previously they
1531 returned an arbitrary result based on the relative ordering of id(float) and
1532 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001533
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001534- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001535 argument `-` which tells it to read files to compile from stdin. Each line is
1536 read on demand and the named file is compiled immediately. (Original patch by
1537 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001538
Georg Brandlfee0f442010-05-22 21:26:21 +00001539- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1540 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001542- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1543 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001544 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001545
Georg Brandlfee0f442010-05-22 21:26:21 +00001546- Comparisons using one of <, <=, >, >= between a complex instance and a
1547 Fractions instance now raise TypeError instead of returning True/False. This
1548 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1549 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001550
Michael Foorde6410c52010-03-29 20:04:23 +00001551- Addition of ``WeakSet`` to the ``weakref`` module.

1559
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001560- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001561 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1562 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001563
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001564- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1565 deprecated.
1566
Georg Brandlfee0f442010-05-22 21:26:21 +00001567- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1568 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001569

1574 existing at the same time, causing a Unicode error when configuration code
1575 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001576
Georg Brandlfee0f442010-05-22 21:26:21 +00001577- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
1578 when logging occurs.

Antoine Pitroueee91cd2010-03-26 19:27:16 +00001580- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
1581 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1582 reads and writes are always retried by OpenSSL itself.

1590 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +00001591
Matthias Klose8b411682010-03-16 10:48:52 +00001592- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
1593 with Tcl/Tk-8.5.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001604- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001605 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1606 log file to compute the next rollover time. If the log file does not exist,
1607 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001608
Georg Brandlba83f822010-03-14 09:50:54 +00001609- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001617- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1618 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1619 This is a behavior change, so email's minor version number is now bumped, to
1620 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001648- Issue #8300: When passing a non-integer argument to struct.pack with any
1649 integer format code, struct.pack first attempts to convert the non-integer
1650 using its __index__ method. If that method is non-existent or raises
1651 TypeError it goes on to try the __int__ method, as described below.
1652
Georg Brandlba83f822010-03-14 09:50:54 +00001653- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1654 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1655 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001656 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1657 inconsistent: __int__ was used for some integer codes but not for others, and
1658 the set of integer codes for which it was used differed between native packing
1659 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002066- The ``__complex__()`` method is now looked up on the class of instances to

2071
Mark Dickinson1b34d252010-01-01 17:27:30 +00002072- Issue #5080: A number of functions and methods previously produced a

2074 These functions and methods now raise TypeError instead. The majority of the

2076 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2077 and many unicode/str methods.

2093 internal representation of a long.

2244 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002245
Georg Brandlba83f822010-03-14 09:50:54 +00002246- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2247 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002248
Georg Brandlba83f822010-03-14 09:50:54 +00002249- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002259
Georg Brandlba83f822010-03-14 09:50:54 +00002260- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2261 decimal string that's guaranteed to round back to x under correct rounding
2262 (with round-half-to-even rounding mode). Previously it gave a string based on
2263 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2264 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2265 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002266
Georg Brandlba83f822010-03-14 09:50:54 +00002267- Issue #7117: On almost all platforms: float-to-string and string-to-float
2268 conversions within Python are now correctly rounded. Places these conversions
2269 occur include: str for floats and complex numbers; the float and complex
2270 constructors; old-style and new-style numeric formatting; serialization and
2271 deserialization of floats and complex numbers using marshal, pickle and json;
2272 parsing of float and imaginary literals in Python code; Decimal-to-float
2273 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002274
Georg Brandlba83f822010-03-14 09:50:54 +00002275 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2276 providing correctly-rounded strtod and dtoa C functions. This code is
2277 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2278 the C compiler. There may be a small number of platforms on which correct
2279 operation of this code cannot be guaranteed, so the code is not used: notably,
2280 this applies to platforms where the C double format is not IEEE 754 binary64,
2281 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2282 and Python's configure script is unable to determine how to change the FPU
2283 precision. On these platforms conversions use the platform strtod and dtoa,
2284 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002285
Georg Brandlba83f822010-03-14 09:50:54 +00002286- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2287 uses the correctly-rounded string <-> float conversions described above (when
2288 available), and so produces correctly rounded results that will display nicely
2289 under the float repr. There are two related small changes: (1) round now
2290 accepts any class with an ``__index__()`` method for its second argument (but
2291 no longer accepts floats for the second argument), and (2) an excessively
2292 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2293 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002440- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2441 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2442 but with at least one decimal point and with a default precision
2443 of 12. Previously, the behavior the same but with a default precision of 6.
2444 This more closely matches ``str()``, and reduces surprises when adding
2445 alignment flags to the empty presentation type. This also affects the new
2446 complex.__format__ in the same way.

2643
Georg Brandlba83f822010-03-14 09:50:54 +00002644- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2645 file objects with closefd=False. The file descriptor is still kept open but
2646 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00002670- On windows, ``os.chdir()`` given unicode was not working if
2671 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2672 this code path is really executed because I cannot move to such directory on
2673 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002675- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2676 element is temporarily replaced with an equivalent frozenset. But the
2677 eventual KeyError would always report the empty ``frozenset()`` as the missing
2678 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002698- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2699 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2700 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2701 of using the replace error handler in PyUnicode_DecodeUTF8().
2702
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002703- Issue #3739: The unicode-internal encoder now reports the number of characters

2705
Georg Brandlba83f822010-03-14 09:50:54 +00002706- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2708 gives improved memory leak detection when running under Valgrind, while taking
2709 advantage of pymalloc at other times.

3954 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00003956- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3957 regression tests in parallel, shortening the total runtime.
3958
Georg Brandlba83f822010-03-14 09:50:54 +00003959- Issue #5354: New test support function import_fresh_module() makes it easy to
3960 import both normal and optimised versions of modules. test_heapq and
3961 test_warnings have been adjusted to use it, tests for other modules with both
3962 C and Python implementations in the stdlib can be adjusted to use it over
3963 time.

3973 support, which does the conversion.

4075
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004076- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4077 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4078 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4079 ``printf`` function, whereas PyString_FromFormat has an independent
4080 implementation and uses "%zd" on all platforms for size_t values.
4081 This makes a difference on win64, where ``printf`` needs "%Id" to display
4082 64bit values.

4088 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004099 was correctly parsed but parsing of subsequent arguments failed.
4100
Vinay Sajip35e3b032008-09-01 14:33:59 +00004101- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004102 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4103 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4104 when given a tuple of classes as second argument, were looking up
4105 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4106 type object.
4107

4246================================
4247
Barry Warsaw07a4a382008-08-21 01:15:08 +00004248*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004249
4250Core and Builtins
4251-----------------
4252
Guido van Rossumf8402962008-08-20 15:01:50 +00004253- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4254 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4255 extensions do not automatically benefit from the class attribute
4256 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4257 to their tp_flags field if they care. This is a backwards
4258 compatibility feature; in 3.0, all types will use the cache by
4259 default.
4260
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004261- Keyword arguments can now follow starred arguments. (``f(a, *args,
4262 keyword=23)`` is now valid syntax.)
4263
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004264- ctypes function pointers that are COM methods have a boolean True
4265 value again.
4266
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004267- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4268 by denying s# to parse objects that have a releasebuffer procedure,
4269 and introducing s*.
4270
Georg Brandl1e13ea92008-08-11 09:07:59 +00004271- Issue #3537: Fix an assertion failure when an empty but presized dict
4272 object was stored in the freelist.
4273
Mark Dickinsonb6467572008-08-04 21:30:09 +00004274- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4275 ValueError consistently across platforms.
4276
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004277- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4278 (64bit Unix, for example), unichr() would truncate its argument and return
4279 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4280
Neal Norwitze7d8be82008-07-31 17:17:14 +00004281- Apply security patches from Apple.
4282
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004283- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4284 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4285
Antoine Pitrou92f82162008-07-25 22:22:08 +00004286- Issue #1819: function calls with several named parameters are now on
4287 average 35% faster (as measured by pybench).
4288
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004289- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4290 the python debugger steps into a class statement: the free variables (local
4291 variables defined in an outer scope) would be deleted from the outer scope.
4292
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004293- Issue #2620: Overflow checking when allocating or reallocating memory
4294 was not always being done properly in some python types and extension
4295 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4296 all been updated to perform better checks and places in the code that
4297 would previously leak memory on the error path when such an allocation
4298 failed have been fixed.
4299
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004300Library
4301-------
4302
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004303- Issue #3612: Added some missing basic types in ctypes.wintypes.
4304
Benjamin Petersone977ad42008-08-20 01:42:01 +00004305- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4306 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4307
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004308- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4309 version reported by these tools does not necessarily follow the python
4310 version numbering scheme, so the module is less strict when parsing it.
4311
Nick Coghlanf70385a2008-08-18 12:42:46 +00004312- Issue #2235: Added Py3k warnings for types which will become unhashable
4313 under the stricter __hash__ inheritance rules in 3.0. Several types
4314 which did not meet the rules for hash invariants and were already
4315 unhashable in 3.0 have now been explicitly flagged as unhashable in
4316 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4317 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4318
Brett Cannon88f801d2008-08-18 00:46:22 +00004319- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4320 imported into the module but exposed as part of the module's API.
4321
Brett Cannon7b96f072008-08-18 00:41:11 +00004322- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4323
Brett Cannon46225e72008-08-18 00:36:52 +00004324- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4325
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004326- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4327
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004328- Issue #3575: Incremental decoder's decode function now takes bytearray
4329 by using 's*' instead of 't#'.
4330
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004331- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004332 fails unicode conversion on 2nd parameter. (windows only)
4333
Georg Brandl222e2082010-08-01 22:27:39 +00004334- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004335 in a redirect.
4336
Brett Cannonabe423e2008-08-16 21:47:07 +00004337- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004338 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004339
Facundo Batistaeb90b782008-08-16 14:44:07 +00004340- Issue #2776: fixed small issue when handling an URL with double slash
4341 after a 302 response in the case of not going through a proxy.
4342
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004343- Issue #2676: in the email package, content-type parsing was hanging on
4344 pathological input because of quadratic or exponential behaviour of a
4345 regular expression.
4346
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004347- Issue #3476: binary buffered reading through the new "io" library is now
4348 thread-safe.
4349
Brett Cannonbf3157b2008-08-14 05:00:03 +00004350- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4351 since mimetools itself is deprecated. Because modules are cached, all
4352 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4353
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004354- Issue #3134: shutil referenced undefined WindowsError symbol.
4355
Robert Schuppenies14646332008-08-10 11:01:53 +00004356- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4357 menu entries were not deleted.
4358
Brett Cannon83e81842008-08-09 23:30:55 +00004359- Copied the implementation of reduce() to _functools.reduce() to have a
4360 version that did not raise a DeprecationWarning under -3.
4361
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004362- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4363 a MemoryError rather than silently stop the iteration.
4364
Guido van Rossum59ce9012008-08-09 14:55:34 +00004365- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4366 to _sre.compile() will now be rejected. This should not affect anybody
4367 since the re.compile() function never generates invalid re-bytecode.
4368
Skip Montanaroa032bf42008-08-08 22:52:51 +00004369- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4370 upon first access it can be automatically initialized from the csv file if
4371 it wasn't initialized during instantiation.
4372
Brett Cannon3aa2a492008-08-06 22:28:09 +00004373- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4374 the reload() built-in has been removed.
4375
Brett Cannon7e30b672008-08-04 21:52:25 +00004376- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004377 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004378 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4379 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4380 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4381 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4382 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004383
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004384- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4385 raised an AttributeError.
4386
Benjamin Peterson01a24322008-07-28 23:35:27 +00004387- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004388 asking for a specific length. This problem only affected files opened
4389 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004390
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004391- Issue #3449: Update decimal module to use most recent specification
4392 (v. 1.68) and tests (v. 2.58) from IBM.
4393
Georg Brandl222e2082010-08-01 22:27:39 +00004394- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004395

4398
Georg Brandlf9efabb2008-07-23 15:16:45 +00004399- Deprecate the "ast" parser function aliases.
4400
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004401- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4402
4403- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4404 invalid arguments.
4405
4406- Issue #3302: Fix several crashes when calling locale's gettext functions
4407 with None arguments.
4408
4409- Issue #3389: Allow resolving dotted names for handlers in logging
4410 configuration files.
4411

4413
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004414- Issue #3394: zipfile.writestr sets external attributes when passed a
4415 file name rather than a ZipInfo instance, so files are extracted with
4416 mode 0600 rather than 000 under Unix.
4417
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004418- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4419 argument in python 2.5, this broke code that subclassed Popen to include its
4420 own poll method. Fixed my moving _deadstate to an _internal_poll method.
4421
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00004422Build
4423-----

4428-------------
4429
Nick Coghlan6e8fef02008-08-18 13:14:22 +00004430- Issue #2235: the C API function PyObject_HashNotImplemented and its
4431 interaction with the tp_hash slot (added in 2.6b2) are now documented
4432
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004433- Issue #643841: The language reference now provides more detailed
4434 coverage of the lookup process for special methods. The disclaimers
4435 regarding lack of coverage of new-style classes have also been
4436 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004439What's New in Python 2.6 beta 2?
4440================================
4441
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004442*Release date: 17-Jul-2008*
4443
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004444Core and Builtins
4445-----------------
4446
Georg Brandl3e483f62008-07-16 22:57:41 +00004447- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4448 its methods now allow for items objects that can be converted to
4449 an integer using operator.index().
4450
Mark Dickinson64b7e502008-07-16 09:40:03 +00004451- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4452 produced a ValueError instead of giving the correct float.
4453
Eric Smitha5fa5a22008-07-16 00:11:49 +00004454- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4455 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4456
Mark Dickinson7103aa42008-07-15 19:08:33 +00004457- Issue #3008: the float type has a new instance method 'float.hex'
4458 and a new class method 'float.fromhex' to convert floating-point
4459 numbers to and from hexadecimal strings, respectively.
4460
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004461- Issue #2235: __hash__ is once again inherited by default. To allow
4462 collections.Hashable to remain meaningful in the presence of the
4463 default hash implementation (object.__hash__), it is now possible
4464 to explicit block inheritance of hash by setting __hash__=None at
4465 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4466 level.
4467
Nick Coghlanb028f502008-07-13 14:52:36 +00004468- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4469 the parent module cannot be found while performing an absolute import.
4470 This means that an incorrectly defined __package__ attribute will
4471 now only prevent relative imports in that module rather than causing
4472 all imports from that module to fail.
4473
Nick Coghlan14ff9942008-07-08 14:21:42 +00004474- Issue #2517: Allow unicode messages in Exceptions again by correctly
4475 bypassing the instance dictionary when looking up __unicode__ on
4476 new-style classes.
4477
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004478- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4479 set to a custom object whose write() method happens to install
4480 another file in sys.stdout.
4481
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004482- Issue #3088: Corrected a race condition in classes derived from
4483 threading.local: the first member set by a thread could be saved in
4484 another thread's dictionary.
4485
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004486- Issue #3004: Minor change to slice.indices(): the start and stop
4487 arguments are now treated identically, making the behaviour easier
4488 to describe and understand. For example, slice(None, -10,
4489 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4490 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4491 10, -1).
4492
Georg Brandl278fc502008-07-19 12:46:12 +00004493- Issue #3219: Calling a function with repeated keyword arguments,
4494 f(a=2, a=23), would not cause a syntax error. This was a regression
4495 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004496
Georg Brandl278fc502008-07-19 12:46:12 +00004497- Issue #2862: Make int and float freelist management consistent with
4498 other freelists. Changes their CompactFreeList apis into
4499 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004500

4502-------
4503
Thomas Heller57adf222008-08-14 19:10:48 +00004504- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4505 api functions without holding the GIL, which could lead to a fatal
4506 error when they failed.
4507
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004508- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004516- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4517 ForkingPickler.register() to resolve conflict with ctypes.
4518
Vinay Sajip51e65192008-07-18 09:01:10 +00004519- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

4522 a valid dlerror() message.
4523
Thomas Heller2bad6572008-07-15 17:19:50 +00004524- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4525 incomplete structure was created.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00004529- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4530

4944 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004945 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004946
4947 This is controlled by the configure argument ``--with-universal-archs``:
4948
4949 - ``--with-universal-archs=all``: install 4-way universal
4950
4951 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4952
4953 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4954
4955 This option should be used in combination with ``--enable-universalsdk=``.
4956
4957 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

4994 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00004995
Christian Heimese74c8f22008-04-19 02:23:57 +00004996- Added kill, terminate and send_signal(sig) to subprocess.Popen.
4997
Georg Brandl3ee81df2008-05-17 18:14:43 +00004998- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
4999 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00005000

Georg Brandl3ee81df2008-05-17 18:14:43 +00005007- Issue #1631171: Re-implement the 'warnings' module in C (the
5008 original Python code has been kept as backup). This will allow for
5009 using the 'warning's machinery in such places as the parser where
5010 use of pure Python code is not possible. Both the ``showarning()``
5011 and ``formatwarning()`` gain an optional 'line' argument which is
5012 not called by default for backwards-compatibility reasons. Setting
5013 ``warnings.showwarning()`` to an implementation that lacks support
5014 for the ``line`` argument will raise a DeprecationWarning.

5038
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005039- The getpass module has been improved on Unix. It now uses /dev/tty
5040 by default and uses stderr instead of stdout. A GetPassWarning is
5041 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00005042

Georg Brandl3ee81df2008-05-17 18:14:43 +00005056- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005057 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005077- Issue #2550: The approach used by client/server code for obtaining
5078 ports to listen on in network-oriented tests has been refined in an
5079 effort to facilitate running multiple instances of the entire
5080 regression test suite in parallel without issue.
5081 test_support.bind_port() has been fixed such that it will always
5082 return a unique port -- which wasn't always the case with the
5083 previous implementation, especially if socket options had been set
5084 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5085 new implementation of bind_port() will actually raise an exception
5086 if it is passed an AF_INET/SOCK_STREAM socket with either the
5087 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5088 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5089 the socket it's been passed. This currently only applies to
5090 Windows. This option prevents any other sockets from binding to the
5091 host/port we've bound to, thus removing the possibility of the
5092 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5093 when a second SOCK_STREAM socket binds and accepts to a host/port
5094 that's already been bound by another socket. The optional preferred
5095 port parameter to bind_port() has been removed. Under no
5096 circumstances should tests be hard coding ports!
5097
5098 test_support.find_unused_port() has also been introduced, which will
5099 pass a temporary socket object to bind_port() in order to obtain an
5100 unused port. The temporary socket object is then closed and
5101 deleted, and the port is returned. This method should only be used
5102 for obtaining an unused port in order to pass to an external program
5103 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5104 a parameter to a server-oriented class that doesn't give you direct
5105 access to the underlying socket used.
5106
5107 Finally, test_support.HOST has been introduced, which should be used
5108 for the host argument of any relevant socket calls (i.e. bind and
5109 connect).

5385
Fred Drakea8ee94b2008-03-01 02:45:07 +00005386- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005387 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005388
Georg Brandlad61bc82008-02-23 15:11:18 +00005389- Issue #2067: file.__exit__() now calls subclasses' close() method.
5390
5391- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005392
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005393- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005394 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005395
Eric Smitha73fbe72008-02-23 03:09:44 +00005396- Added the future_builtins module, which contains hex() and oct().
5397 These are the PEP 3127 version of these functions, designed to be
5398 compatible with the hex() and oct() builtins from Python 3.0. They
5399 differ slightly in their output formats from the existing, unchanged
5400 Python 2.6 builtins. The expected usage of the future_builtins
5401 module is:
5402 from future_builtins import hex, oct
5403
Eric Smith7ef40bf2008-02-20 23:34:22 +00005404- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5405 exponents for exponents with absolute value < 100. Follows C99
5406 standard. This is a change on Windows, which would use 3 digits.
5407 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5408 so that any alterations it does to the resulting string will be
5409 available in stringlib/formatter.h (for float.__format__).
5410
Eric Smith5a3c1352008-02-19 13:21:56 +00005411- Implemented PEP 3101, Advanced String Formatting. This adds a new
5412 builtin format(); a format() method for str and unicode; a
5413 __format__() method to object, str, unicode, int, long, float, and
5414 datetime; the class string.Formatter; and the C API
5415 PyObject_Format().
5416
Georg Brandl3ee81df2008-05-17 18:14:43 +00005417- Fixed several potential crashes, all caused by specially crafted
5418 __del__ methods exploiting objects in temporarily inconsistent
5419 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005420
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005421- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005422 prevent a possible crash: an Abstract Base Class would try to access
5423 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005424
Georg Brandl3ee81df2008-05-17 18:14:43 +00005425- Fixed repr() and str() of complex numbers with infinity or nan as
5426 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005427
Georg Brandl3ee81df2008-05-17 18:14:43 +00005428- Clear all free lists during a gc.collect() of the highest generation
5429 in order to allow pymalloc to free more arenas. Python may give back
5430 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005431
Georg Brandl3ee81df2008-05-17 18:14:43 +00005432- Issue #2045: Fix an infinite recursion triggered when printing a
5433 subclass of collections.defaultdict, if its default_factory is set
5434 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005435
Christian Heimesf75dbef2008-02-08 00:11:31 +00005436- Fixed a minor memory leak in dictobject.c. The content of the free
5437 list was not freed on interpreter shutdown.
5438
Georg Brandl21e99f42010-03-07 15:23:59 +00005439- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005440 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005441
Georg Brandl3ee81df2008-05-17 18:14:43 +00005442- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5443 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005444 to compact the internal free lists of pre-allocted ints and floats.
5445
Georg Brandl3ee81df2008-05-17 18:14:43 +00005446- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5447 calls. Python expected the return type int but the fork familie
5448 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005449
Georg Brandl3ee81df2008-05-17 18:14:43 +00005450- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5451 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005452
Georg Brandl3ee81df2008-05-17 18:14:43 +00005453- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5454 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005455
Georg Brandl3ee81df2008-05-17 18:14:43 +00005456- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5457 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005458
Georg Brandl3ee81df2008-05-17 18:14:43 +00005459- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5460 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005461
Georg Brandl3ee81df2008-05-17 18:14:43 +00005462- Patch #1473257: generator objects gain a gi_code attribute. This is
5463 the same object as the func_code attribute of the function that
5464 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005465
Georg Brandl3ee81df2008-05-17 18:14:43 +00005466- Issue #1920: "while 0" statements were completely removed by the
5467 compiler, even in the presence of an "else" clause, which is
5468 supposed to be run when the condition is false. Now the compiler
5469 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005470
Guido van Rossumeead05f2008-01-24 18:21:02 +00005471- A few crashers fixed: weakref_in_del.py (issue #1377858);
5472 loosing_dict_ref.py (issue #1303614, test67.py);
5473 borrowed_ref_[34].py (not in tracker).
5474
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005475- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005476 suppressed while an extension is loaded by calling SetErrorMode in
5477 dynload_win.c. The error is still reported properly.
5478
Georg Brandl3ee81df2008-05-17 18:14:43 +00005479- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005480 several extension methods and modules do not work without unicode
5481 support.
5482
Georg Brandl26543b12008-01-21 18:36:51 +00005483- Issue #1882: when compiling code from a string, encoding cookies in the
5484 second line of code were not always recognized correctly.
5485
Georg Brandl14404b62008-01-19 19:27:05 +00005486- Issue #1679: "0x" was taken as a valid integer literal.
5487
Georg Brandl6caad7d2008-01-26 14:19:22 +00005488- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005489 added.
5490
Christian Heimesc94e2b52008-01-14 04:13:37 +00005491- sys.float_info / PyFloat_GetInfo: The floating point information
5492 object was converted from a dict to a specialized structseq object.
5493
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494- Patch #1816: Added sys.flags structseq. It exposes the status of
5495 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005496
Georg Brandl3ee81df2008-05-17 18:14:43 +00005497- Objects/structseq.c: Implemented new structseq representation. The
5498 patch makes structseqs (e.g. the return value of os.stat) more
5499 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005500
Georg Brandl3ee81df2008-05-17 18:14:43 +00005501- Patch #1700288: added a type attribute cache that caches method
5502 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005503
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005504- Bug #1776: __import__() no longer accepts filenames on any platform.
5505 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005506

5508
Georg Brandl3ee81df2008-05-17 18:14:43 +00005509- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5510 envvar and sys.dont_write_bytecode attribute. All these can be set
5511 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005512
Georg Brandl3ee81df2008-05-17 18:14:43 +00005513- Improve some exception messages when Windows fails to load an
5514 extension module. Now we get for example '%1 is not a valid Win32
5515 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005516
Georg Brandl3ee81df2008-05-17 18:14:43 +00005517- Bug #1481296: Fixed long(float('nan')) != 0L.

5520 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005521
Christian Heimes0a8143f2007-12-18 23:22:54 +00005522- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005523 and INF. float("nan"), float("inf") and float("-inf") now work on
5524 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005525
Georg Brandl3ee81df2008-05-17 18:14:43 +00005526- Compiler now generates simpler and faster code for dictionary
5527 literals. The oparg for BUILD_MAP now indicates an estimated
5528 dictionary size. There is a new opcode, STORE_MAP, for adding
5529 entries to the dictionary.

5561 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005562
Georg Brandl3ee81df2008-05-17 18:14:43 +00005563- Issue #1265: Fix a problem with sys.settrace, if the tracing
5564 function uses a generator expression when at the same time the
5565 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005566
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005567- sets and frozensets now have an isdisjoint() method.

5572
Georg Brandl21e99f42010-03-07 15:23:59 +00005573- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005574 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5575 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005576
Georg Brandl3ee81df2008-05-17 18:14:43 +00005577- Issue #1686386: Tuple's tp_repr did not take into account the
5578 possibility of having a self-referential tuple, which is possible
5579 from C code. Nor did object's tp_str consider that a type's tp_str
5580 could do something that could lead to an inifinite recursion.
5581 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5582 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005583
Georg Brandl3ee81df2008-05-17 18:14:43 +00005584- Issue #1164: It was possible to trigger deadlock when using the
5585 'print' statement to write to a file since the GIL was not released
5586 as needed. Now PyObject_Print() does the right thing along with
5587 various tp_print implementations of the built-in types and those in
5588 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005590- Issue #1147: Exceptions were directly allowing string exceptions in
5591 their throw() method even though string exceptions no longer
5592 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00005597- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005598 PyObject_Call() never calling back out to Python code to trigger
5599 recursion depth updates/checks. Required the creation of a static
5600 RuntimeError instance in case normalizing an exception put the
5601 recursion check value past its limit. Fixes crashers
5602 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005617- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005618 __*__ attributes. (Some already existed, e.g., __doc__ and
5619 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005620
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005621- Add -3 option to the interpreter to warn about features that are

5625 calls.
5626
Collin Winter62903052007-05-18 23:11:24 +00005627- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005628 "except E as target:". This is to provide forwards compatibility
5629 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005630
Brett Cannon229cee22007-05-05 01:34:02 +00005631- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005636- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005637 setting a plain string, ie don't expand to single letter identifiers.
5638
Raymond Hettinger13936692007-04-11 18:40:58 +00005639- Request #1191699: Slices can now be pickled.
5640
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005641- Request #1193128: str.translate() now allows a None argument for
5642 translations that only remove characters without re-mapping the
5643 remaining characters.
5644
Georg Brandl5cb76c12007-03-21 09:00:39 +00005645- Patch #1682205: a TypeError while unpacking an iterable is no longer

5649
Guido van Rossum143b5642007-03-23 04:58:42 +00005650- Bug #1683368: The object.__init__() and object.__new__() methods are
5651 now stricter in rejecting excess arguments. The only time when
5652 either allows excess arguments is when it is not overridden and the
5653 other one is. For backwards compatibility, when both are
5654 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005655 warning later). Also, type.__init__() insists on the same signature
5656 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005657
Georg Brandl3ee81df2008-05-17 18:14:43 +00005658- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5659 object to complex using its __complex__() method before falling back
5660 to the __float__() method. Therefore, the functions in the cmath
5661 module now can operate on objects that define a __complex__()
5662 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005680- Bug #1678647: write a newline after printing an exception in any
5681 case, even when converting the value to a string failed.
5682
Georg Brandl871f1bc2007-03-12 13:17:36 +00005683- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005684 its argument, if it exists. If not, it will work like before. This
5685 allows customizing the output of dir() in the presence of a
5686 __getattr__().

5695 parthensized forms. This means complex(repr(x)) now works instead of
5696 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005697
Georg Brandlaa2321b2007-03-07 00:40:28 +00005698- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005699 makes the filenames the warning module prints much more sensible
5700 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005713- Patch #1674228: when assigning a slice (old-style), check for the
5714 sq_ass_slice instead of the sq_slice slot.
5715
Georg Brandl3ee81df2008-05-17 18:14:43 +00005716- When printing an unraisable error, don't print exceptions. before

6327 Python would crash instead of raising an error.
6328

6341
Georg Brandl3ee81df2008-05-17 18:14:43 +00006342- unittest now verifies more of its assumptions. In particular,

6344 accepted in TestSuite.addTest(). This should cause no
6345 incompatibility since it never made sense with ordinary subclasses
6346 -- the failure just occurred later, with a more cumbersome
6347 exception.

6630 obtained from the TLS negotiation itself. Patch contributed by Bill
6631 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006632
Georg Brandl3ee81df2008-05-17 18:14:43 +00006633- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006634 that the SMTP.starttls() caller no longer needs to call ehlo()
6635 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006636 does not claim to support starttls. Adds the
6637 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6718 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6719 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00006736 time so that opening a database previously created with the DB_DUP
6737 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6738 opens. Specifically: dictionary assignment to a DB object will
6739 replace all values for a given key when the database allows
6740 duplicate values. DB users should use DB.put(k, v) when they want
6741 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006742

6748 characters with ASCII value less than 32. Also, it correctly quotes
6749 dots only if they occur on a single line, as opposed to the previous
6750 behavior of quoting dots if they are the second character of any
6751 line.

7074-----
7075
Georg Brandl3ee81df2008-05-17 18:14:43 +00007076- Unified naming convention for free lists and their limits. All free
7077 lists in Object/ are named ``free_list``, the counter ``numfree``
7078 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7079 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007080
Georg Brandl3ee81df2008-05-17 18:14:43 +00007081- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7082 to ``PyTuple_SetItem``, it can be used to populate a brand new
7083 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007084
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007085- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007087- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7088 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7089 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007090
7091- Patch #1720595: add T_BOOL to the range of structmember types.
7092
7093- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7094 ``PyFloat_GetInfo()`` to the float API.
7095
Georg Brandl3ee81df2008-05-17 18:14:43 +00007096- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7097 of w# format code incorrectly truncated the length to an int, even
7098 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7099 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007100
Georg Brandl3ee81df2008-05-17 18:14:43 +00007101- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7102 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007103
Georg Brandl3ee81df2008-05-17 18:14:43 +00007104- PEP 3123: Provide forward compatibility with Python 3.0, while
7105 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7106 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007107
Georg Brandl3ee81df2008-05-17 18:14:43 +00007108- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7109 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007110
7111- Patch #1733960: Allow T_LONGLONG to accept ints.
7112
7113- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7114

7118
7119- Fix some leftovers from the conversion from int to Py_ssize_t
7120 (relevant to strings and sequences of more than 2**31 items).
7121
7122- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7123 outside of pystate.c and should not be necessary.
7124
Georg Brandl3ee81df2008-05-17 18:14:43 +00007125- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7126 absolute imports. In earlier versions they might have used relative
7127 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007128
Georg Brandl3ee81df2008-05-17 18:14:43 +00007129- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7130 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007131
Georg Brandl3ee81df2008-05-17 18:14:43 +00007132- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7133 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007139- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7140 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7141 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7142 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007143
Georg Brandl3ee81df2008-05-17 18:14:43 +00007144- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00007157- Removed the macfs module. It had been deprecated since Python 2.5.
7158 This lead to the deprecation of macostools.touched() as it relied
7159 solely on macfs and was a no-op under OS X.
