Antoine Pitrou5a72e762011-01-07 21:49:44 +0000302- Issue #10827: Changed the rules for 2-digit years. The time.asctime

305 accepted by ``time.mktime`` and ``time.strftime`` is still system
306 dependent, but ``time.mktime`` will now accept full range supported
307 by the OS. Conversion of 2-digit years to 4-digit is deprecated.

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

793
Daniel Stutzbach91287322010-08-24 21:09:30 +0000794- Issue #8750: Fixed MutableSet's methods to correctly handle

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001219- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1220 start byte and the continuation byte(s) are now considered invalid, instead
1221 of the number of bytes specified by the start byte.
1222 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1223 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1224 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1225 Previous versions returned a single u'\ufffd'.
1226
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001227- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001228 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1229 arises from the "Overriding __eq__ blocks inheritance ..." warning
1230 when turned into an exception: in this case the exception simply
1231 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001232
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001233- Issue #8748: Fix two issues with comparisons between complex and integer
1234 objects. (1) The comparison could incorrectly return True in some cases
1235 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1236 (2) The comparison raised an OverflowError for large integers, leading
1237 to unpredictable exceptions when combining integers and complex objects
1238 in sets or dicts.
1239
Mark Dickinson81336372010-05-30 12:12:25 +00001240- Issue #5211: Implicit coercion for the complex type is now completely
1241 removed. (Coercion for arithmetic operations was already removed in 2.7
1242 alpha 4, but coercion for rich comparisons was accidentally left in.)
1243
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001244- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
1245 and error handler, instead of writing to the C stderr file in utf-8
1246
Georg Brandlfee0f442010-05-22 21:26:21 +00001247- Issue #7902: When using explicit relative import syntax, don't try implicit
1248 relative import semantics.

1379 using its __int__ method. Previously, only small arguments were treated this

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001605- Issue #7301: Add environment variable $PYTHONWARNINGS.
1606
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001607- Issue #8329: Don't return the same lists from select.select when no fds are
1608 changed.
1609
Georg Brandlfee0f442010-05-22 21:26:21 +00001610- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001611 on 64-bit machines. The shift count for either left or right shift is
1612 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00001620- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1621 with a non-empty format string. This is an effort to future-proof user
1622 code. If a derived class does not currently implement __format__ but later
1623 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001624 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001625 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001675- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1676 InvalidOperation instead of returning False. (Comparisons involving a quiet
1677 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal

Georg Brandlfee0f442010-05-22 21:26:21 +00001680- Issue #2531: Comparison operations between floats and Decimal instances now
1681 return a result based on the numeric values of the operands; previously they
1682 returned an arbitrary result based on the relative ordering of id(float) and
1683 id(Decimal).

Georg Brandlba83f822010-03-14 09:50:54 +00001996- Issue #7242: On Solaris 9 and earlier calling ``os.fork()`` from within a
Gregory P. Smith9e5d1322010-03-01 01:22:39 +00001997 thread could raise an incorrect RuntimeError about not holding the import
1998 lock. The import lock is now reinitialized after fork.

Georg Brandlba83f822010-03-14 09:50:54 +00002019- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00002020 is run with the -OO flag. Tests requiring docstrings are skipped.
2021
Georg Brandlba83f822010-03-14 09:50:54 +00002022- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
2023 now also used by regrtest to run all the tests in a temporary directory. The
2024 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
2025 Xicluna who helped with the patch.

2042 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002043 library would return a bogus result; on Solaris, it was possible to crash the
2044 interpreter. Patch by Stefan Krah.

Mark Dickinson36ecd672010-01-29 17:11:39 +00002056
Georg Brandlba83f822010-03-14 09:50:54 +00002057- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2058 and add the additional members returned in an OSVERSIONINFOEX structure. The
2059 new members are service_pack_major, service_pack_minor, suite_mask, and
2060 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00002061
Georg Brandlba83f822010-03-14 09:50:54 +00002062- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2063 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2064 returning NULL. The macro now returns a statically allocated empty string
2065 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00002066
Antoine Pitrou64672132010-01-13 07:55:48 +00002067- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

2075 strings,
2076 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2077 numeric strings corresponding to subnormal values,
2078 (3) a memory leak for some values large enough to cause overflow, and
2079 (4) a number of flaws that could lead to incorrectly rounded results.

2082 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +00002083

R. David Murray63e4fd72010-02-10 22:42:04 +00002096- Issue #7835: shelve should no longer produce mysterious warnings during
2097 interpreter shutdown.
2098
Georg Brandlba83f822010-03-14 09:50:54 +00002099- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
2100 XML processing instructions and comments. These raw characters are allowed
2101 by the XML specification, and are necessary when outputting e.g. PHP code in
2102 a processing instruction. Patch by Neil Muller.

Georg Brandlba83f822010-03-14 09:50:54 +00002108- Issue #7851: logging: Clarification on logging configuration files.
Vinay Sajip0e6e97d2010-02-04 20:23:45 +00002109
Antoine Pitroud840e512010-02-04 20:20:18 +00002110- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002111 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002112 Also, raise ValueError rather than TypeError when an unknown TIPC address
2113 type is specified. Patch by Brian Curtin.
2114
Vinay Sajip28c382f2010-02-04 18:48:53 +00002115- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002117- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002118 file position when calling `truncate()`. It would previously change the file
2119 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002120 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2121
Georg Brandlba83f822010-03-14 09:50:54 +00002122- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2123 class used to represent files stored inside an archive. The new
2124 implementation is significantly faster and can be wrapped in a
2125 ``io.BufferedReader`` object for more speedups. It also solves an issue
2126 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2127 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00002128

Benjamin Petersona43f34c2010-01-25 03:31:13 +00002136
Georg Brandlba83f822010-03-14 09:50:54 +00002137- Issue #7748: Since unicode values are supported for some metadata options in
2138 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2139 encoded string for them. This ensures that the upload and register commands
2140 send the correct values to PyPI without any error.

2216
Georg Brandlba83f822010-03-14 09:50:54 +00002217- The ``__complex__()`` method is now looked up on the class of instances to
2218 make it consistent with other special methods.

2222
Mark Dickinson1b34d252010-01-01 17:27:30 +00002223- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002224 DeprecationWarning when passed a float argument where an integer was expected.
2225 These functions and methods now raise TypeError instead. The majority of the
2226 effects of this change are in the extension modules, but some core functions
2227 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2228 and many unicode/str methods.

2242 of integers: the result of a/b is now correctly rounded for ints a and b (at
2243 least on IEEE 754 platforms), and in particular does not depend on the
2244 internal representation of a long.

2252
Georg Brandlba83f822010-03-14 09:50:54 +00002253 These executables now work properly with the arch(1) command: ``arch -ppc

2402 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002411- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2412 decimal string that's guaranteed to round back to x under correct rounding
2413 (with round-half-to-even rounding mode). Previously it gave a string based on
2414 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2415 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2416 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002418- Issue #7117: On almost all platforms: float-to-string and string-to-float
2419 conversions within Python are now correctly rounded. Places these conversions
2420 occur include: str for floats and complex numbers; the float and complex
2421 constructors; old-style and new-style numeric formatting; serialization and
2422 deserialization of floats and complex numbers using marshal, pickle and json;
2423 parsing of float and imaginary literals in Python code; Decimal-to-float
2424 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002425
Georg Brandlba83f822010-03-14 09:50:54 +00002426 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2427 providing correctly-rounded strtod and dtoa C functions. This code is
2428 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2429 the C compiler. There may be a small number of platforms on which correct
2430 operation of this code cannot be guaranteed, so the code is not used: notably,
2431 this applies to platforms where the C double format is not IEEE 754 binary64,
2432 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2433 and Python's configure script is unable to determine how to change the FPU
2434 precision. On these platforms conversions use the platform strtod and dtoa,
2435 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002437- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2438 uses the correctly-rounded string <-> float conversions described above (when
2439 available), and so produces correctly rounded results that will display nicely
2440 under the float repr. There are two related small changes: (1) round now
2441 accepts any class with an ``__index__()`` method for its second argument (but
2442 no longer accepts floats for the second argument), and (2) an excessively
2443 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2444 raises an exception.

2671 internal representation of integers, for performance reasons. Base 2**30 is
2672 enabled by default on 64-bit machines. Add --enable-big-digits option to

2859 gives improved memory leak detection when running under Valgrind, while taking
2860 advantage of pymalloc at other times.

4027 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4028 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004227- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

4229 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4230 ``printf`` function, whereas PyString_FromFormat has an independent
4231 implementation and uses "%zd" on all platforms for size_t values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004249 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004250 was correctly parsed but parsing of subsequent arguments failed.
4251
Vinay Sajip35e3b032008-09-01 14:33:59 +00004252- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004253 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4254 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4255 when given a tuple of classes as second argument, were looking up
4256 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4257 type object.
4258
Neal Norwitz18aa3882008-08-24 05:04:52 +00004259- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +00004267- Silenced another compiler warning about a used but not defined
4268 function 'stringlib_contains_obj'.
4269
Benjamin Peterson712ee922008-08-24 18:10:20 +00004270- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
4271 ``__delslice__``.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004328 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4329 for catch_warnings() also led to an improvement in the raising of a
4330 DeprecationWarning related to warnings.warn_explicit().
4331

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004355- Issue #2975: When compiling several extension modules with Visual Studio 2008
4356 from the same python interpreter, some environment variables would grow
4357 without limit.
4358
Benjamin Peterson37346b22008-08-23 20:27:43 +00004359- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004396What's New in Python 2.6 beta 3?
4397================================
4398
Barry Warsaw07a4a382008-08-21 01:15:08 +00004399*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004400
4401Core and Builtins
4402-----------------
4403
Guido van Rossumf8402962008-08-20 15:01:50 +00004404- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4405 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4406 extensions do not automatically benefit from the class attribute
4407 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4408 to their tp_flags field if they care. This is a backwards
4409 compatibility feature; in 3.0, all types will use the cache by
4410 default.
4411
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004412- Keyword arguments can now follow starred arguments. (``f(a, *args,
4413 keyword=23)`` is now valid syntax.)
4414
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004415- ctypes function pointers that are COM methods have a boolean True
4416 value again.
4417
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004418- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4419 by denying s# to parse objects that have a releasebuffer procedure,
4420 and introducing s*.
4421
Georg Brandl1e13ea92008-08-11 09:07:59 +00004422- Issue #3537: Fix an assertion failure when an empty but presized dict
4423 object was stored in the freelist.
4424
Mark Dickinsonb6467572008-08-04 21:30:09 +00004425- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4426 ValueError consistently across platforms.
4427
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004428- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4429 (64bit Unix, for example), unichr() would truncate its argument and return
4430 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4431
Neal Norwitze7d8be82008-07-31 17:17:14 +00004432- Apply security patches from Apple.
4433
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004434- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4435 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4436
Antoine Pitrou92f82162008-07-25 22:22:08 +00004437- Issue #1819: function calls with several named parameters are now on
4438 average 35% faster (as measured by pybench).
4439
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004440- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4441 the python debugger steps into a class statement: the free variables (local
4442 variables defined in an outer scope) would be deleted from the outer scope.
4443
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004444- Issue #2620: Overflow checking when allocating or reallocating memory
4445 was not always being done properly in some python types and extension
4446 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4447 all been updated to perform better checks and places in the code that
4448 would previously leak memory on the error path when such an allocation
4449 failed have been fixed.

4452-------
4453
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004454- Issue #3612: Added some missing basic types in ctypes.wintypes.
4455
Benjamin Petersone977ad42008-08-20 01:42:01 +00004456- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4457 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4458
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004459- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4460 version reported by these tools does not necessarily follow the python
4461 version numbering scheme, so the module is less strict when parsing it.
4462
Nick Coghlanf70385a2008-08-18 12:42:46 +00004463- Issue #2235: Added Py3k warnings for types which will become unhashable
4464 under the stricter __hash__ inheritance rules in 3.0. Several types
4465 which did not meet the rules for hash invariants and were already
4466 unhashable in 3.0 have now been explicitly flagged as unhashable in
4467 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4468 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4469
Brett Cannon88f801d2008-08-18 00:46:22 +00004470- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4471 imported into the module but exposed as part of the module's API.
4472
Brett Cannon7b96f072008-08-18 00:41:11 +00004473- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4474
Brett Cannon46225e72008-08-18 00:36:52 +00004475- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004477- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4478
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004479- Issue #3575: Incremental decoder's decode function now takes bytearray
4480 by using 's*' instead of 't#'.
4481
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004482- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004483 fails unicode conversion on 2nd parameter. (windows only)
4484
Georg Brandl222e2082010-08-01 22:27:39 +00004485- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004486 in a redirect.
4487
Brett Cannonabe423e2008-08-16 21:47:07 +00004488- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004489 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004490
Facundo Batistaeb90b782008-08-16 14:44:07 +00004491- Issue #2776: fixed small issue when handling an URL with double slash
4492 after a 302 response in the case of not going through a proxy.
4493
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004494- Issue #2676: in the email package, content-type parsing was hanging on
4495 pathological input because of quadratic or exponential behaviour of a
4496 regular expression.
4497
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004498- Issue #3476: binary buffered reading through the new "io" library is now
4499 thread-safe.
4500
Brett Cannonbf3157b2008-08-14 05:00:03 +00004501- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4502 since mimetools itself is deprecated. Because modules are cached, all
4503 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4504
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004505- Issue #3134: shutil referenced undefined WindowsError symbol.
4506
Robert Schuppenies14646332008-08-10 11:01:53 +00004507- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4508 menu entries were not deleted.
4509
Brett Cannon83e81842008-08-09 23:30:55 +00004510- Copied the implementation of reduce() to _functools.reduce() to have a
4511 version that did not raise a DeprecationWarning under -3.
4512
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004513- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4514 a MemoryError rather than silently stop the iteration.
4515
Guido van Rossum59ce9012008-08-09 14:55:34 +00004516- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4517 to _sre.compile() will now be rejected. This should not affect anybody
4518 since the re.compile() function never generates invalid re-bytecode.
4519
Skip Montanaroa032bf42008-08-08 22:52:51 +00004520- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4521 upon first access it can be automatically initialized from the csv file if
4522 it wasn't initialized during instantiation.
4523
Brett Cannon3aa2a492008-08-06 22:28:09 +00004524- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4525 the reload() built-in has been removed.
4526
Brett Cannon7e30b672008-08-04 21:52:25 +00004527- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004528 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004529 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,

4592
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004593*Release date: 17-Jul-2008*

4596-----------------
4597
Georg Brandl3e483f62008-07-16 22:57:41 +00004598- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4599 its methods now allow for items objects that can be converted to
4600 an integer using operator.index().
4601
Mark Dickinson64b7e502008-07-16 09:40:03 +00004602- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4603 produced a ValueError instead of giving the correct float.
4604
Eric Smitha5fa5a22008-07-16 00:11:49 +00004605- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4606 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4607
Mark Dickinson7103aa42008-07-15 19:08:33 +00004608- Issue #3008: the float type has a new instance method 'float.hex'
4609 and a new class method 'float.fromhex' to convert floating-point
4610 numbers to and from hexadecimal strings, respectively.
4611
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004612- Issue #2235: __hash__ is once again inherited by default. To allow
4613 collections.Hashable to remain meaningful in the presence of the
4614 default hash implementation (object.__hash__), it is now possible
4615 to explicit block inheritance of hash by setting __hash__=None at
4616 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4617 level.
4618
Nick Coghlanb028f502008-07-13 14:52:36 +00004619- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4620 the parent module cannot be found while performing an absolute import.
4621 This means that an incorrectly defined __package__ attribute will
4622 now only prevent relative imports in that module rather than causing
4623 all imports from that module to fail.
4624
Nick Coghlan14ff9942008-07-08 14:21:42 +00004625- Issue #2517: Allow unicode messages in Exceptions again by correctly

4635 another thread's dictionary.
4636
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004637- Issue #3004: Minor change to slice.indices(): the start and stop
4638 arguments are now treated identically, making the behaviour easier
4639 to describe and understand. For example, slice(None, -10,
4640 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4641 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4642 10, -1).
4643
Georg Brandl278fc502008-07-19 12:46:12 +00004644- Issue #3219: Calling a function with repeated keyword arguments,
4645 f(a=2, a=23), would not cause a syntax error. This was a regression
4646 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00004648- Issue #2862: Make int and float freelist management consistent with
4649 other freelists. Changes their CompactFreeList apis into

4656 api functions without holding the GIL, which could lead to a fatal
4657 error when they failed.
4658
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004659- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004684- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4685 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004686 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004687 content-length. The problem had been corrected in the 2.4 branch, but never
4688 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004703- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4704 handling is now the same as that of other special attributes like __name__).
4705
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004706- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

5098 This is controlled by the configure argument ``--with-universal-archs``:
5099
5100 - ``--with-universal-archs=all``: install 4-way universal
5101
5102 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5103
5104 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5105
5106 This option should be used in combination with ``--enable-universalsdk=``.

5116- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00005117
5118- The PyString functions have been renamed to PyBytes. A batch of
5119 defines were added so that the linker still sees the original
5120 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005158- Issue #1631171: Re-implement the 'warnings' module in C (the
5159 original Python code has been kept as backup). This will allow for
5160 using the 'warning's machinery in such places as the parser where
5161 use of pure Python code is not possible. Both the ``showarning()``
5162 and ``formatwarning()`` gain an optional 'line' argument which is
5163 not called by default for backwards-compatibility reasons. Setting
5164 ``warnings.showwarning()`` to an implementation that lacks support
5165 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005207- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005208 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005228- Issue #2550: The approach used by client/server code for obtaining
5229 ports to listen on in network-oriented tests has been refined in an
5230 effort to facilitate running multiple instances of the entire
5231 regression test suite in parallel without issue.
5232 test_support.bind_port() has been fixed such that it will always
5233 return a unique port -- which wasn't always the case with the
5234 previous implementation, especially if socket options had been set
5235 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5236 new implementation of bind_port() will actually raise an exception
5237 if it is passed an AF_INET/SOCK_STREAM socket with either the
5238 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5239 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5240 the socket it's been passed. This currently only applies to
5241 Windows. This option prevents any other sockets from binding to the
5242 host/port we've bound to, thus removing the possibility of the
5243 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5244 when a second SOCK_STREAM socket binds and accepts to a host/port
5245 that's already been bound by another socket. The optional preferred
5246 port parameter to bind_port() has been removed. Under no
5247 circumstances should tests be hard coding ports!
5248
5249 test_support.find_unused_port() has also been introduced, which will
5250 pass a temporary socket object to bind_port() in order to obtain an
5251 unused port. The temporary socket object is then closed and
5252 deleted, and the port is returned. This method should only be used
5253 for obtaining an unused port in order to pass to an external program
5254 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5255 a parameter to a server-oriented class that doesn't give you direct
5256 access to the underlying socket used.
5257
5258 Finally, test_support.HOST has been introduced, which should be used
5259 for the host argument of any relevant socket calls (i.e. bind and
5260 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005261
5262 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005263 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005264 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5265 test_asynchat and test_socket_ssl.
5266
Georg Brandl3ee81df2008-05-17 18:14:43 +00005267 It is now possible for multiple instances of the regression test
5268 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005547- Added the future_builtins module, which contains hex() and oct().
5548 These are the PEP 3127 version of these functions, designed to be
5549 compatible with the hex() and oct() builtins from Python 3.0. They
5550 differ slightly in their output formats from the existing, unchanged
5551 Python 2.6 builtins. The expected usage of the future_builtins
5552 module is:
5553 from future_builtins import hex, oct
5554
Eric Smith7ef40bf2008-02-20 23:34:22 +00005555- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5556 exponents for exponents with absolute value < 100. Follows C99
5557 standard. This is a change on Windows, which would use 3 digits.
5558 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5559 so that any alterations it does to the resulting string will be
5560 available in stringlib/formatter.h (for float.__format__).
5561
Eric Smith5a3c1352008-02-19 13:21:56 +00005562- Implemented PEP 3101, Advanced String Formatting. This adds a new
5563 builtin format(); a format() method for str and unicode; a
5564 __format__() method to object, str, unicode, int, long, float, and
5565 datetime; the class string.Formatter; and the C API
5566 PyObject_Format().
5567
Georg Brandl3ee81df2008-05-17 18:14:43 +00005568- Fixed several potential crashes, all caused by specially crafted
5569 __del__ methods exploiting objects in temporarily inconsistent
5570 state.

5581 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005582
Georg Brandl3ee81df2008-05-17 18:14:43 +00005583- Issue #2045: Fix an infinite recursion triggered when printing a
5584 subclass of collections.defaultdict, if its default_factory is set
5585 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005586
Christian Heimesf75dbef2008-02-08 00:11:31 +00005587- Fixed a minor memory leak in dictobject.c. The content of the free

5596
Georg Brandl3ee81df2008-05-17 18:14:43 +00005597- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5598 calls. Python expected the return type int but the fork familie
5599 returns pi_t.

5614 the same object as the func_code attribute of the function that
5615 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005616
Georg Brandl3ee81df2008-05-17 18:14:43 +00005617- Issue #1920: "while 0" statements were completely removed by the
5618 compiler, even in the presence of an "else" clause, which is
5619 supposed to be run when the condition is false. Now the compiler
5620 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005621
Guido van Rossumeead05f2008-01-24 18:21:02 +00005622- A few crashers fixed: weakref_in_del.py (issue #1377858);
5623 loosing_dict_ref.py (issue #1303614, test67.py);
5624 borrowed_ref_[34].py (not in tracker).
5625
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005626- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005627 suppressed while an extension is loaded by calling SetErrorMode in
5628 dynload_win.c. The error is still reported properly.
5629
Georg Brandl3ee81df2008-05-17 18:14:43 +00005630- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005631 several extension methods and modules do not work without unicode
5632 support.
5633
Georg Brandl26543b12008-01-21 18:36:51 +00005634- Issue #1882: when compiling code from a string, encoding cookies in the
5635 second line of code were not always recognized correctly.
5636
Georg Brandl14404b62008-01-19 19:27:05 +00005637- Issue #1679: "0x" was taken as a valid integer literal.
5638
Georg Brandl6caad7d2008-01-26 14:19:22 +00005639- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005640 added.
5641
Christian Heimesc94e2b52008-01-14 04:13:37 +00005642- sys.float_info / PyFloat_GetInfo: The floating point information
5643 object was converted from a dict to a specialized structseq object.
5644
Georg Brandl3ee81df2008-05-17 18:14:43 +00005645- Patch #1816: Added sys.flags structseq. It exposes the status of
5646 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005647
Georg Brandl3ee81df2008-05-17 18:14:43 +00005648- Objects/structseq.c: Implemented new structseq representation. The
5649 patch makes structseqs (e.g. the return value of os.stat) more
5650 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005651
Georg Brandl3ee81df2008-05-17 18:14:43 +00005652- Patch #1700288: added a type attribute cache that caches method
5653 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005654
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005655- Bug #1776: __import__() no longer accepts filenames on any platform.
5656 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005657
Georg Brandlaed6c662008-01-07 17:25:53 +00005658- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5659
Georg Brandl3ee81df2008-05-17 18:14:43 +00005660- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5661 envvar and sys.dont_write_bytecode attribute. All these can be set
5662 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005663
Georg Brandl3ee81df2008-05-17 18:14:43 +00005664- Improve some exception messages when Windows fails to load an
5665 extension module. Now we get for example '%1 is not a valid Win32
5666 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005667
Georg Brandl3ee81df2008-05-17 18:14:43 +00005668- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00005669
Georg Brandl3ee81df2008-05-17 18:14:43 +00005670- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5671 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005672
Christian Heimes0a8143f2007-12-18 23:22:54 +00005673- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005674 and INF. float("nan"), float("inf") and float("-inf") now work on
5675 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005676
Georg Brandl3ee81df2008-05-17 18:14:43 +00005677- Compiler now generates simpler and faster code for dictionary
5678 literals. The oparg for BUILD_MAP now indicates an estimated
5679 dictionary size. There is a new opcode, STORE_MAP, for adding
5680 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005681
Georg Brandl3ee81df2008-05-17 18:14:43 +00005682- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00005683
Georg Brandl3ee81df2008-05-17 18:14:43 +00005684- Issue #1620: New property decorator syntax was modifying the
5685 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00005686
Georg Brandl3ee81df2008-05-17 18:14:43 +00005687- Issue #1538: Avoid copying string in split/rsplit if the split char
5688 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005689
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005690- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005691 SystemError.
5692
Nick Coghlanef01d822007-12-03 12:55:17 +00005693- PEP 366: Allow explicit relative imports when executing modules
5694 inside packages with the -m switch via a new module level
5695 __package__ attribute.
5696
Georg Brandl3ee81df2008-05-17 18:14:43 +00005697- Issue #1402: Fix a crash on exit, when another thread is still
5698 running, and if the deallocation of its frames somehow calls the
5699 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005700
Christian Heimes28104c52007-11-27 23:16:44 +00005701- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
5702
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00005703- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005704 attribute of an empty cell object.
5705
Georg Brandl3ee81df2008-05-17 18:14:43 +00005706- Issue #1460: The utf-7 incremental decoder did not accept truncated
5707 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005708
Georg Brandl3ee81df2008-05-17 18:14:43 +00005709- Patch #1739468: Directories and zipfiles containing a __main__.py
5710 file can now be directly executed by passing their name to the
5711 interpreter. The directory/zipfile is automatically inserted as the
5712 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005713
Georg Brandl3ee81df2008-05-17 18:14:43 +00005714- Issue #1265: Fix a problem with sys.settrace, if the tracing
5715 function uses a generator expression when at the same time the
5716 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005717
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005718- sets and frozensets now have an isdisjoint() method.
5719
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005720- optimize the performance of builtin.sum().
5721
Neal Norwitz44f326e2007-10-05 05:29:17 +00005722- Fix warnings found by the new version of the Coverity checker.
5723
Georg Brandl21e99f42010-03-07 15:23:59 +00005724- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005725 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5726 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005727
Georg Brandl3ee81df2008-05-17 18:14:43 +00005728- Issue #1686386: Tuple's tp_repr did not take into account the
5729 possibility of having a self-referential tuple, which is possible
5730 from C code. Nor did object's tp_str consider that a type's tp_str
5731 could do something that could lead to an inifinite recursion.
5732 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5733 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005734
Georg Brandl3ee81df2008-05-17 18:14:43 +00005735- Issue #1164: It was possible to trigger deadlock when using the
5736 'print' statement to write to a file since the GIL was not released
5737 as needed. Now PyObject_Print() does the right thing along with
5738 various tp_print implementations of the built-in types and those in
5739 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005740
Georg Brandl3ee81df2008-05-17 18:14:43 +00005741- Issue #1147: Exceptions were directly allowing string exceptions in
5742 their throw() method even though string exceptions no longer
5743 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005744
Georg Brandl3ee81df2008-05-17 18:14:43 +00005745- Issue #1096: Prevent a segfault from getting the repr of a very
5746 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005747
Brett Cannon1e534b52007-09-07 04:18:30 +00005748- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005749 PyObject_Call() never calling back out to Python code to trigger
5750 recursion depth updates/checks. Required the creation of a static
5751 RuntimeError instance in case normalizing an exception put the
5752 recursion check value past its limit. Fixes crashers
5753 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005754
Georg Brandl3ee81df2008-05-17 18:14:43 +00005755- Patch #1031213: Decode source line in SyntaxErrors back to its
5756 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00005758- Patch #1673759: add a missing overflow check when formatting floats
5759 with %G.
5760
Georg Brandl3ee81df2008-05-17 18:14:43 +00005761- Prevent expandtabs() on string and unicode objects from causing a
5762 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00005763

Georg Brandla5ea6892007-06-01 11:33:33 +00005767
Neal Norwitz0ac60192007-05-27 04:08:54 +00005768- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005769 __*__ attributes. (Some already existed, e.g., __doc__ and
5770 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005771
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005772- Add -3 option to the interpreter to warn about features that are
5773 deprecated and will be changed/removed in Python 3.0.
5774
Georg Brandl2134e752007-05-21 20:34:16 +00005775- Patch #1686487: you can now pass any mapping after '**' in function
5776 calls.
5777
Collin Winter62903052007-05-18 23:11:24 +00005778- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005779 "except E as target:". This is to provide forwards compatibility
5780 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005781
Brett Cannon229cee22007-05-05 01:34:02 +00005782- Deprecate BaseException.message as per PEP 352.
5783
Georg Brandl3ee81df2008-05-17 18:14:43 +00005784- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005785 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005786
Vinay Sajip8549ce32007-05-06 17:53:37 +00005787- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005788 setting a plain string, ie don't expand to single letter identifiers.
5789
Raymond Hettinger13936692007-04-11 18:40:58 +00005790- Request #1191699: Slices can now be pickled.
5791
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005792- Request #1193128: str.translate() now allows a None argument for
5793 translations that only remove characters without re-mapping the
5794 remaining characters.
5795
Georg Brandl5cb76c12007-03-21 09:00:39 +00005796- Patch #1682205: a TypeError while unpacking an iterable is no longer
5797 masked by a generic one with the message "unpack non-sequence".
5798
Neal Norwitzaa754b72007-03-21 06:39:48 +00005799- Remove unused file Python/fmod.c.
5800
Guido van Rossum143b5642007-03-23 04:58:42 +00005801- Bug #1683368: The object.__init__() and object.__new__() methods are
5802 now stricter in rejecting excess arguments. The only time when
5803 either allows excess arguments is when it is not overridden and the
5804 other one is. For backwards compatibility, when both are
5805 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005806 warning later). Also, type.__init__() insists on the same signature
5807 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005808
Georg Brandl3ee81df2008-05-17 18:14:43 +00005809- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5810 object to complex using its __complex__() method before falling back
5811 to the __float__() method. Therefore, the functions in the cmath
5812 module now can operate on objects that define a __complex__()
5813 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005814
Georg Brandl3ee81df2008-05-17 18:14:43 +00005815- Patch #1623563: allow __class__ assignment for classes with
5816 __slots__. The old and the new class are still required to have the
5817 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005818
Georg Brandl3ee81df2008-05-17 18:14:43 +00005819- Patch #1642547: Fix an error/crash when encountering syntax errors
5820 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005822- Patch #1462488: Python no longer segfaults when
5823 ``object.__reduce_ex__()`` is called with an object that is faking
5824 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005825
Georg Brandl3ee81df2008-05-17 18:14:43 +00005826- Patch #1680015: Don't modify __slots__ tuple if it contains an
5827 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00005829- Patch #1444529: the builtin compile() now accepts keyword arguments.
5830
Georg Brandl7b9c5552007-03-12 14:30:05 +00005831- Bug #1678647: write a newline after printing an exception in any
5832 case, even when converting the value to a string failed.
5833
Georg Brandl871f1bc2007-03-12 13:17:36 +00005834- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005835 its argument, if it exists. If not, it will work like before. This
5836 allows customizing the output of dir() in the presence of a
5837 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005838
Collin Winter276887b2007-03-12 16:11:39 +00005839- Patch #922167: Python no longer segfaults when faced with infinitely
5840 self-recursive reload() calls (as reported by bug #742342).
5841
Georg Brandl3ee81df2008-05-17 18:14:43 +00005842- Patch #1675981: remove unreachable code from ``type.__new__()``
5843 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00005844
Georg Brandl3ee81df2008-05-17 18:14:43 +00005845- Patch #1491866: change the complex() constructor to allow
5846 parthensized forms. This means complex(repr(x)) now works instead of
5847 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005848
Georg Brandlaa2321b2007-03-07 00:40:28 +00005849- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005850 makes the filenames the warning module prints much more sensible

6359
Facundo Batistad918a652007-04-24 13:54:38 +00006360- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006361 the client's request was successfully received, understood, and
6362 accepted. Now in these cases no error is raised in urllib (issue
6363 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00006364

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006371- Added a timeout parameter to the constructor of other protocols
6372 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6373 work started with create_connection() and timeout in httplib, and
6374 closes patch #723312.
6375
Vinay Sajip8549ce32007-05-06 17:53:37 +00006376- Patch #1676823: Added create_connection() to socket.py, which may be
6377 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006378 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006379
Martin v. Löwis0af33882007-03-23 13:27:15 +00006380- Bug #978833: Revert r50844, as it broke _socketobject.dup.

6400
Georg Brandlf66b6032007-03-14 08:27:52 +00006401- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006402 AttributeError instead of an IOError when the server's response
6403 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006404
Georg Brandl3ee81df2008-05-17 18:14:43 +00006405- Patch #957650: "%var%" environment variable references are now
6406 properly expanded in ntpath.expandvars(), also "~user" home
6407 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00006408
Georg Brandl3ee81df2008-05-17 18:14:43 +00006409- Patch #1429539: pdb now correctly initializes the __main__ module
6410 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006411 correctly now.
6412
Georg Brandlbad6f192007-03-13 21:32:56 +00006413- The nonobvious commands.getstatus() function is now deprecated.

6419
Georg Brandl3ee81df2008-05-17 18:14:43 +00006420- Patch #1530482: add pydoc.render_doc() which returns the
6421 documentation for a thing instead of paging it to stdout, which
6422 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00006423
Georg Brandl3ee81df2008-05-17 18:14:43 +00006424- Patch #1533909: the timeit module now accepts callables in addition

6430 parameter which can be set to False to prevent the default
6431 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00006432
Georg Brandl9e6b4702007-03-13 18:15:41 +00006433- Patch #1581073: add a flag to textwrap that prevents the dropping of

6435
Georg Brandl92a6bae2007-03-13 17:43:32 +00006436- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006437 are set for invalid interpolation sequences that would lead to
6438 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00006439

6452
Georg Brandl94fe3f52007-03-13 09:32:11 +00006453- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00006454 field names in its exception message if you try to write a record
6455 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00006473

6481 returned string up to the first NUL character.
6482

6492
Georg Brandl3ee81df2008-05-17 18:14:43 +00006493- unittest now verifies more of its assumptions. In particular,
6494 TestCase and TestSuite subclasses (not instances) are no longer
6495 accepted in TestSuite.addTest(). This should cause no
6496 incompatibility since it never made sense with ordinary subclasses
6497 -- the failure just occurred later, with a more cumbersome
6498 exception.

6507 given a unicode argument and os.listdir() returns unicode filenames.
6508
Georg Brandl3ee81df2008-05-17 18:14:43 +00006509- Patch #1673619: setup.py identifies extension modules it doesn't

6511 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006887 time so that opening a database previously created with the DB_DUP
6888 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6889 opens. Specifically: dictionary assignment to a DB object will
6890 replace all values for a given key when the database allows
6891 duplicate values. DB users should use DB.put(k, v) when they want
6892 to store duplicates; not DB[k] = v.

6899 characters with ASCII value less than 32. Also, it correctly quotes
6900 dots only if they occur on a single line, as opposed to the previous
6901 behavior of quoting dots if they are the second character of any
6902 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006903
