Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000379- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
380 start byte and the continuation byte(s) are now considered invalid, instead
381 of the number of bytes specified by the start byte.
382 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
383 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
384 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
385 Previous versions returned a single u'\ufffd'.

389 arises from the "Overriding __eq__ blocks inheritance ..." warning

394 objects. (1) The comparison could incorrectly return True in some cases
395 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
396 (2) The comparison raised an OverflowError for large integers, leading
397 to unpredictable exceptions when combining integers and complex objects
398 in sets or dicts.

766
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000767- Issue #8329: Don't return the same lists from select.select when no fds are
768 changed.

781 with a non-empty format string. This is an effort to future-proof user
782 code. If a derived class does not currently implement __format__ but later
783 adds its own __format__, it would most likely break user code that had
784 supplied a format string. This will be changed to a DeprecationWaring in
785 Python 3.3 and it will be an error in Python 3.4.

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000845- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000846 argument `-` which tells it to read files to compile from stdin. Each line is
847 read on demand and the named file is compiled immediately. (Original patch by
848 Piotr Ożarowski).

970 and standard packing.)

1219 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1220 returning NULL. The macro now returns a statically allocated empty string
1221 instead.

1231 strings,
1232 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1233 numeric strings corresponding to subnormal values,

Antoine Pitroud840e512010-02-04 20:20:18 +00001266- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001267 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001268 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001273- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001274 file position when calling `truncate()`. It would previously change the file
1275 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001276 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1277

1279 class used to represent files stored inside an archive. The new
1280 implementation is significantly faster and can be wrapped in a
1281 ``io.BufferedReader`` object for more speedups. It also solves an issue
1282 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1283 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001293- Issue #7748: Since unicode values are supported for some metadata options in

1295 encoded string for them. This ensures that the upload and register commands

Georg Brandlba83f822010-03-14 09:50:54 +00001373- The ``__complex__()`` method is now looked up on the class of instances to
1374 make it consistent with other special methods.

1378
Mark Dickinson1b34d252010-01-01 17:27:30 +00001379- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001380 DeprecationWarning when passed a float argument where an integer was expected.
1381 These functions and methods now raise TypeError instead. The majority of the
1382 effects of this change are in the extension modules, but some core functions
1383 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1384 and many unicode/str methods.

1399 least on IEEE 754 platforms), and in particular does not depend on the
1400 internal representation of a long.

1558 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00001567- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1568 decimal string that's guaranteed to round back to x under correct rounding
1569 (with round-half-to-even rounding mode). Previously it gave a string based on
1570 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1571 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1572 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001574- Issue #7117: On almost all platforms: float-to-string and string-to-float
1575 conversions within Python are now correctly rounded. Places these conversions
1576 occur include: str for floats and complex numbers; the float and complex
1577 constructors; old-style and new-style numeric formatting; serialization and
1578 deserialization of floats and complex numbers using marshal, pickle and json;
1579 parsing of float and imaginary literals in Python code; Decimal-to-float
1580 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001581
Georg Brandlba83f822010-03-14 09:50:54 +00001582 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1583 providing correctly-rounded strtod and dtoa C functions. This code is
1584 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1585 the C compiler. There may be a small number of platforms on which correct
1586 operation of this code cannot be guaranteed, so the code is not used: notably,
1587 this applies to platforms where the C double format is not IEEE 754 binary64,
1588 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1589 and Python's configure script is unable to determine how to change the FPU
1590 precision. On these platforms conversions use the platform strtod and dtoa,
1591 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001593- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1594 uses the correctly-rounded string <-> float conversions described above (when
1595 available), and so produces correctly rounded results that will display nicely
1596 under the float repr. There are two related small changes: (1) round now
1597 accepts any class with an ``__index__()`` method for its second argument (but
1598 no longer accepts floats for the second argument), and (2) an excessively
1599 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1600 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00001817- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00001818 untrackable objects are not tracked by the garbage collector. This can reduce
1819 the size of collections and therefore the garbage collection overhead on
1820 long-running programs, depending on their particular use of datatypes.

1827 internal representation of integers, for performance reasons. Base 2**30 is
1828 enabled by default on 64-bit machines. Add --enable-big-digits option to
1829 configure, which overrides the default. Add sys.long_info structseq to
1830 provide information about the internal format.

1861
Georg Brandl29c6a282009-04-05 20:23:13 +00001862- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00001863 were suppressing all exceptions. These include list(), filter(), map(),

1865
Benjamin Peterson596d3062009-01-19 15:42:23 +00001866- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00001893- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1894 existing .py counterpart, override the co_filename attributes of all code
1895 objects if the original filename is obsolete (which can happen if the file has
1896 been renamed, moved, or if it is accessed through different paths). Patch by

1950
Georg Brandlba83f822010-03-14 09:50:54 +00001951- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1952 file objects with closefd=False. The file descriptor is still kept open but
1953 the file object behaves like a closed file. The ``FileIO`` object also got a

1979 this code path is really executed because I cannot move to such directory on

2006 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Antoine Pitrou0668c622008-08-26 22:42:08 +00003409 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3410 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3411 when given a tuple of classes as second argument, were looking up
3412 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3413 type object.
3414
Neal Norwitz18aa3882008-08-24 05:04:52 +00003415- Fix crashes on memory allocation failure found with failmalloc.

3424 function 'stringlib_contains_obj'.
3425
Benjamin Peterson712ee922008-08-24 18:10:20 +00003426- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

Brett Cannon1eaf0742008-09-02 01:25:16 +00003484 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3485 for catch_warnings() also led to an improvement in the raising of a
3486 DeprecationWarning related to warnings.warn_explicit().
3487

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003552What's New in Python 2.6 beta 3?
3553================================
3554
Barry Warsaw07a4a382008-08-21 01:15:08 +00003555*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003556
3557Core and Builtins
3558-----------------
3559
Guido van Rossumf8402962008-08-20 15:01:50 +00003560- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3561 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3562 extensions do not automatically benefit from the class attribute
3563 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3564 to their tp_flags field if they care. This is a backwards
3565 compatibility feature; in 3.0, all types will use the cache by
3566 default.
3567
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003568- Keyword arguments can now follow starred arguments. (``f(a, *args,
3569 keyword=23)`` is now valid syntax.)
3570
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003571- ctypes function pointers that are COM methods have a boolean True
3572 value again.
3573
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003574- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3575 by denying s# to parse objects that have a releasebuffer procedure,
3576 and introducing s*.
3577
Georg Brandl1e13ea92008-08-11 09:07:59 +00003578- Issue #3537: Fix an assertion failure when an empty but presized dict
3579 object was stored in the freelist.
3580
Mark Dickinsonb6467572008-08-04 21:30:09 +00003581- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3582 ValueError consistently across platforms.
3583
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003584- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3585 (64bit Unix, for example), unichr() would truncate its argument and return
3586 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3587
Neal Norwitze7d8be82008-07-31 17:17:14 +00003588- Apply security patches from Apple.
3589
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003590- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3591 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3592
Antoine Pitrou92f82162008-07-25 22:22:08 +00003593- Issue #1819: function calls with several named parameters are now on
3594 average 35% faster (as measured by pybench).
3595
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003596- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3597 the python debugger steps into a class statement: the free variables (local
3598 variables defined in an outer scope) would be deleted from the outer scope.
3599
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003600- Issue #2620: Overflow checking when allocating or reallocating memory
3601 was not always being done properly in some python types and extension
3602 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3603 all been updated to perform better checks and places in the code that
3604 would previously leak memory on the error path when such an allocation
3605 failed have been fixed.

3608-------
3609
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003610- Issue #3612: Added some missing basic types in ctypes.wintypes.
3611
Benjamin Petersone977ad42008-08-20 01:42:01 +00003612- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3613 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3614
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003615- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3616 version reported by these tools does not necessarily follow the python
3617 version numbering scheme, so the module is less strict when parsing it.
3618
Nick Coghlanf70385a2008-08-18 12:42:46 +00003619- Issue #2235: Added Py3k warnings for types which will become unhashable
3620 under the stricter __hash__ inheritance rules in 3.0. Several types
3621 which did not meet the rules for hash invariants and were already
3622 unhashable in 3.0 have now been explicitly flagged as unhashable in
3623 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3624 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3625
Brett Cannon88f801d2008-08-18 00:46:22 +00003626- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3627 imported into the module but exposed as part of the module's API.
3628
Brett Cannon7b96f072008-08-18 00:41:11 +00003629- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3630
Brett Cannon46225e72008-08-18 00:36:52 +00003631- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003633- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3634
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003635- Issue #3575: Incremental decoder's decode function now takes bytearray
3636 by using 's*' instead of 't#'.
3637
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003638- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003639 fails unicode conversion on 2nd parameter. (windows only)
3640
Georg Brandl222e2082010-08-01 22:27:39 +00003641- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003642 in a redirect.
3643
Brett Cannonabe423e2008-08-16 21:47:07 +00003644- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003645 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003646
Facundo Batistaeb90b782008-08-16 14:44:07 +00003647- Issue #2776: fixed small issue when handling an URL with double slash
3648 after a 302 response in the case of not going through a proxy.
3649
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003650- Issue #2676: in the email package, content-type parsing was hanging on
3651 pathological input because of quadratic or exponential behaviour of a
3652 regular expression.
3653
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003654- Issue #3476: binary buffered reading through the new "io" library is now
3655 thread-safe.
3656
Brett Cannonbf3157b2008-08-14 05:00:03 +00003657- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3658 since mimetools itself is deprecated. Because modules are cached, all
3659 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3660
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003661- Issue #3134: shutil referenced undefined WindowsError symbol.
3662
Robert Schuppenies14646332008-08-10 11:01:53 +00003663- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3664 menu entries were not deleted.
3665
Brett Cannon83e81842008-08-09 23:30:55 +00003666- Copied the implementation of reduce() to _functools.reduce() to have a
3667 version that did not raise a DeprecationWarning under -3.
3668
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003669- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3670 a MemoryError rather than silently stop the iteration.
3671
Guido van Rossum59ce9012008-08-09 14:55:34 +00003672- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3673 to _sre.compile() will now be rejected. This should not affect anybody
3674 since the re.compile() function never generates invalid re-bytecode.
3675
Skip Montanaroa032bf42008-08-08 22:52:51 +00003676- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3677 upon first access it can be automatically initialized from the csv file if
3678 it wasn't initialized during instantiation.
3679
Brett Cannon3aa2a492008-08-06 22:28:09 +00003680- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3681 the reload() built-in has been removed.
3682
Brett Cannon7e30b672008-08-04 21:52:25 +00003683- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003684 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3687 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3688 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3689 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003690

3752-----------------
3753
Georg Brandl3e483f62008-07-16 22:57:41 +00003754- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3755 its methods now allow for items objects that can be converted to
3756 an integer using operator.index().
3757
Mark Dickinson64b7e502008-07-16 09:40:03 +00003758- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3759 produced a ValueError instead of giving the correct float.
3760
Eric Smitha5fa5a22008-07-16 00:11:49 +00003761- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3762 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3763
Mark Dickinson7103aa42008-07-15 19:08:33 +00003764- Issue #3008: the float type has a new instance method 'float.hex'
3765 and a new class method 'float.fromhex' to convert floating-point
3766 numbers to and from hexadecimal strings, respectively.
3767
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003768- Issue #2235: __hash__ is once again inherited by default. To allow
3769 collections.Hashable to remain meaningful in the presence of the
3770 default hash implementation (object.__hash__), it is now possible
3771 to explicit block inheritance of hash by setting __hash__=None at
3772 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3773 level.
3774
Nick Coghlanb028f502008-07-13 14:52:36 +00003775- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3776 the parent module cannot be found while performing an absolute import.
3777 This means that an incorrectly defined __package__ attribute will
3778 now only prevent relative imports in that module rather than causing
3779 all imports from that module to fail.
3780
Nick Coghlan14ff9942008-07-08 14:21:42 +00003781- Issue #2517: Allow unicode messages in Exceptions again by correctly

3791 another thread's dictionary.
3792
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003793- Issue #3004: Minor change to slice.indices(): the start and stop
3794 arguments are now treated identically, making the behaviour easier
3795 to describe and understand. For example, slice(None, -10,
3796 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3797 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3798 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00003800- Issue #3219: Calling a function with repeated keyword arguments,

3841 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003842 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003843 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003859- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4269
Georg Brandl74a1dea2008-05-28 11:21:39 +00004270- Add ``PyType_Modified()`` as a public API to clear the type cache.
4271
4272- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00004273
4274- The PyString functions have been renamed to PyBytes. A batch of
4275 defines were added so that the linker still sees the original
4276 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004314- Issue #1631171: Re-implement the 'warnings' module in C (the
4315 original Python code has been kept as backup). This will allow for
4316 using the 'warning's machinery in such places as the parser where
4317 use of pure Python code is not possible. Both the ``showarning()``
4318 and ``formatwarning()`` gain an optional 'line' argument which is
4319 not called by default for backwards-compatibility reasons. Setting
4320 ``warnings.showwarning()`` to an implementation that lacks support
4321 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004346- The getpass module has been improved on Unix. It now uses /dev/tty
4347 by default and uses stderr instead of stdout. A GetPassWarning is
4348 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004363- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004364 extension modules between 32 and 64 bit platforms. See the distutls

4377 so the controlled environment will more closely mirror the typical
4378 script environment. This supports setup.py scripts that refer to
4379 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004384- Issue #2550: The approach used by client/server code for obtaining
4385 ports to listen on in network-oriented tests has been refined in an
4386 effort to facilitate running multiple instances of the entire
4387 regression test suite in parallel without issue.
4388 test_support.bind_port() has been fixed such that it will always
4389 return a unique port -- which wasn't always the case with the
4390 previous implementation, especially if socket options had been set
4391 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4392 new implementation of bind_port() will actually raise an exception
4393 if it is passed an AF_INET/SOCK_STREAM socket with either the
4394 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4395 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4396 the socket it's been passed. This currently only applies to
4397 Windows. This option prevents any other sockets from binding to the
4398 host/port we've bound to, thus removing the possibility of the
4399 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4400 when a second SOCK_STREAM socket binds and accepts to a host/port
4401 that's already been bound by another socket. The optional preferred
4402 port parameter to bind_port() has been removed. Under no
4403 circumstances should tests be hard coding ports!
4404
4405 test_support.find_unused_port() has also been introduced, which will
4406 pass a temporary socket object to bind_port() in order to obtain an
4407 unused port. The temporary socket object is then closed and
4408 deleted, and the port is returned. This method should only be used
4409 for obtaining an unused port in order to pass to an external program
4410 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4411 a parameter to a server-oriented class that doesn't give you direct
4412 access to the underlying socket used.
4413
4414 Finally, test_support.HOST has been introduced, which should be used
4415 for the host argument of any relevant socket calls (i.e. bind and
4416 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004417
4418 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004419 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004420 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4421 test_asynchat and test_socket_ssl.
4422
Georg Brandl3ee81df2008-05-17 18:14:43 +00004423 It is now possible for multiple instances of the regression test
4424 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004703- Added the future_builtins module, which contains hex() and oct().
4704 These are the PEP 3127 version of these functions, designed to be
4705 compatible with the hex() and oct() builtins from Python 3.0. They
4706 differ slightly in their output formats from the existing, unchanged
4707 Python 2.6 builtins. The expected usage of the future_builtins
4708 module is:
4709 from future_builtins import hex, oct
4710
Eric Smith7ef40bf2008-02-20 23:34:22 +00004711- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4712 exponents for exponents with absolute value < 100. Follows C99
4713 standard. This is a change on Windows, which would use 3 digits.
4714 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4715 so that any alterations it does to the resulting string will be
4716 available in stringlib/formatter.h (for float.__format__).
4717
Eric Smith5a3c1352008-02-19 13:21:56 +00004718- Implemented PEP 3101, Advanced String Formatting. This adds a new
4719 builtin format(); a format() method for str and unicode; a
4720 __format__() method to object, str, unicode, int, long, float, and
4721 datetime; the class string.Formatter; and the C API
4722 PyObject_Format().
4723
Georg Brandl3ee81df2008-05-17 18:14:43 +00004724- Fixed several potential crashes, all caused by specially crafted
4725 __del__ methods exploiting objects in temporarily inconsistent
4726 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004727
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004728- Issue #2115: Important speedup in setting __slot__ attributes. Also

4737 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004738
Georg Brandl3ee81df2008-05-17 18:14:43 +00004739- Issue #2045: Fix an infinite recursion triggered when printing a
4740 subclass of collections.defaultdict, if its default_factory is set
4741 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004742
Christian Heimesf75dbef2008-02-08 00:11:31 +00004743- Fixed a minor memory leak in dictobject.c. The content of the free

4752
Georg Brandl3ee81df2008-05-17 18:14:43 +00004753- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4754 calls. Python expected the return type int but the fork familie
4755 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004756

Georg Brandl3ee81df2008-05-17 18:14:43 +00004769- Patch #1473257: generator objects gain a gi_code attribute. This is
4770 the same object as the func_code attribute of the function that
4771 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004772
Georg Brandl3ee81df2008-05-17 18:14:43 +00004773- Issue #1920: "while 0" statements were completely removed by the
4774 compiler, even in the presence of an "else" clause, which is

4776 correctly emits bytecode for the "else" suite.

4780 borrowed_ref_[34].py (not in tracker).
4781
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004782- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004783 suppressed while an extension is loaded by calling SetErrorMode in
4784 dynload_win.c. The error is still reported properly.
4785
Georg Brandl3ee81df2008-05-17 18:14:43 +00004786- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004787 several extension methods and modules do not work without unicode
4788 support.
4789
Georg Brandl26543b12008-01-21 18:36:51 +00004790- Issue #1882: when compiling code from a string, encoding cookies in the
4791 second line of code were not always recognized correctly.
4792
Georg Brandl14404b62008-01-19 19:27:05 +00004793- Issue #1679: "0x" was taken as a valid integer literal.
4794
Georg Brandl6caad7d2008-01-26 14:19:22 +00004795- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004796 added.
4797
Christian Heimesc94e2b52008-01-14 04:13:37 +00004798- sys.float_info / PyFloat_GetInfo: The floating point information
4799 object was converted from a dict to a specialized structseq object.
4800
Georg Brandl3ee81df2008-05-17 18:14:43 +00004801- Patch #1816: Added sys.flags structseq. It exposes the status of
4802 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004803
Georg Brandl3ee81df2008-05-17 18:14:43 +00004804- Objects/structseq.c: Implemented new structseq representation. The
4805 patch makes structseqs (e.g. the return value of os.stat) more
4806 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004807
Georg Brandl3ee81df2008-05-17 18:14:43 +00004808- Patch #1700288: added a type attribute cache that caches method
4809 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004810
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004811- Bug #1776: __import__() no longer accepts filenames on any platform.
4812 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004813
Georg Brandlaed6c662008-01-07 17:25:53 +00004814- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4815
Georg Brandl3ee81df2008-05-17 18:14:43 +00004816- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4817 envvar and sys.dont_write_bytecode attribute. All these can be set
4818 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004819
Georg Brandl3ee81df2008-05-17 18:14:43 +00004820- Improve some exception messages when Windows fails to load an
4821 extension module. Now we get for example '%1 is not a valid Win32
4822 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004823

Georg Brandl3ee81df2008-05-17 18:14:43 +00004826- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4827 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004828
Christian Heimes0a8143f2007-12-18 23:22:54 +00004829- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004830 and INF. float("nan"), float("inf") and float("-inf") now work on
4831 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004832
Georg Brandl3ee81df2008-05-17 18:14:43 +00004833- Compiler now generates simpler and faster code for dictionary
4834 literals. The oparg for BUILD_MAP now indicates an estimated
4835 dictionary size. There is a new opcode, STORE_MAP, for adding
4836 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004865- Patch #1739468: Directories and zipfiles containing a __main__.py
4866 file can now be directly executed by passing their name to the
4867 interpreter. The directory/zipfile is automatically inserted as the
4868 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004869
Georg Brandl3ee81df2008-05-17 18:14:43 +00004870- Issue #1265: Fix a problem with sys.settrace, if the tracing
4871 function uses a generator expression when at the same time the
4872 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004873
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004874- sets and frozensets now have an isdisjoint() method.
4875
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004876- optimize the performance of builtin.sum().
4877
Neal Norwitz44f326e2007-10-05 05:29:17 +00004878- Fix warnings found by the new version of the Coverity checker.
4879
Georg Brandl21e99f42010-03-07 15:23:59 +00004880- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004881 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4882 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004883
Georg Brandl3ee81df2008-05-17 18:14:43 +00004884- Issue #1686386: Tuple's tp_repr did not take into account the
4885 possibility of having a self-referential tuple, which is possible
4886 from C code. Nor did object's tp_str consider that a type's tp_str
4887 could do something that could lead to an inifinite recursion.
4888 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4889 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004890
Georg Brandl3ee81df2008-05-17 18:14:43 +00004891- Issue #1164: It was possible to trigger deadlock when using the
4892 'print' statement to write to a file since the GIL was not released
4893 as needed. Now PyObject_Print() does the right thing along with
4894 various tp_print implementations of the built-in types and those in
4895 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004896
Georg Brandl3ee81df2008-05-17 18:14:43 +00004897- Issue #1147: Exceptions were directly allowing string exceptions in
4898 their throw() method even though string exceptions no longer
4899 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004900
Georg Brandl3ee81df2008-05-17 18:14:43 +00004901- Issue #1096: Prevent a segfault from getting the repr of a very
4902 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004903
Brett Cannon1e534b52007-09-07 04:18:30 +00004904- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004905 PyObject_Call() never calling back out to Python code to trigger
4906 recursion depth updates/checks. Required the creation of a static
4907 RuntimeError instance in case normalizing an exception put the
4908 recursion check value past its limit. Fixes crashers
4909 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004910
Georg Brandl3ee81df2008-05-17 18:14:43 +00004911- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004924- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004925 __*__ attributes. (Some already existed, e.g., __doc__ and
4926 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004927
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004928- Add -3 option to the interpreter to warn about features that are
4929 deprecated and will be changed/removed in Python 3.0.
4930
Georg Brandl2134e752007-05-21 20:34:16 +00004931- Patch #1686487: you can now pass any mapping after '**' in function
4932 calls.
4933
Collin Winter62903052007-05-18 23:11:24 +00004934- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004935 "except E as target:". This is to provide forwards compatibility
4936 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004937
Brett Cannon229cee22007-05-05 01:34:02 +00004938- Deprecate BaseException.message as per PEP 352.
4939
Georg Brandl3ee81df2008-05-17 18:14:43 +00004940- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004941 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004942
Vinay Sajip8549ce32007-05-06 17:53:37 +00004943- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004944 setting a plain string, ie don't expand to single letter identifiers.
4945
Raymond Hettinger13936692007-04-11 18:40:58 +00004946- Request #1191699: Slices can now be pickled.
4947
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004948- Request #1193128: str.translate() now allows a None argument for
4949 translations that only remove characters without re-mapping the
4950 remaining characters.
4951
Georg Brandl5cb76c12007-03-21 09:00:39 +00004952- Patch #1682205: a TypeError while unpacking an iterable is no longer
4953 masked by a generic one with the message "unpack non-sequence".
4954
Neal Norwitzaa754b72007-03-21 06:39:48 +00004955- Remove unused file Python/fmod.c.
4956
Guido van Rossum143b5642007-03-23 04:58:42 +00004957- Bug #1683368: The object.__init__() and object.__new__() methods are
4958 now stricter in rejecting excess arguments. The only time when
4959 either allows excess arguments is when it is not overridden and the
4960 other one is. For backwards compatibility, when both are
4961 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004962 warning later). Also, type.__init__() insists on the same signature
4963 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004964
Georg Brandl3ee81df2008-05-17 18:14:43 +00004965- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4966 object to complex using its __complex__() method before falling back
4967 to the __float__() method. Therefore, the functions in the cmath
4968 module now can operate on objects that define a __complex__()
4969 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004970
Georg Brandl3ee81df2008-05-17 18:14:43 +00004971- Patch #1623563: allow __class__ assignment for classes with
4972 __slots__. The old and the new class are still required to have the
4973 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004974
Georg Brandl3ee81df2008-05-17 18:14:43 +00004975- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004978- Patch #1462488: Python no longer segfaults when
4979 ``object.__reduce_ex__()`` is called with an object that is faking
4980 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004981
Georg Brandl3ee81df2008-05-17 18:14:43 +00004982- Patch #1680015: Don't modify __slots__ tuple if it contains an

4986
Georg Brandl7b9c5552007-03-12 14:30:05 +00004987- Bug #1678647: write a newline after printing an exception in any
4988 case, even when converting the value to a string failed.
4989
Georg Brandl871f1bc2007-03-12 13:17:36 +00004990- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004991 its argument, if it exists. If not, it will work like before. This
4992 allows customizing the output of dir() in the presence of a
4993 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004995- Patch #922167: Python no longer segfaults when faced with infinitely
4996 self-recursive reload() calls (as reported by bug #742342).
4997
Georg Brandl3ee81df2008-05-17 18:14:43 +00004998- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005001- Patch #1491866: change the complex() constructor to allow
5002 parthensized forms. This means complex(repr(x)) now works instead of
5003 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005004
Georg Brandlaa2321b2007-03-07 00:40:28 +00005005- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005006 makes the filenames the warning module prints much more sensible
5007 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005008
Georg Brandl49aafc92007-03-07 00:34:46 +00005009- Variant of patch #697613: don't exit the interpreter on a SystemExit
5010 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005011 variable is given, but break into the interactive interpreter just
5012 like on other exceptions or normal program exit.

5515
Facundo Batistad918a652007-04-24 13:54:38 +00005516- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005517 the client's request was successfully received, understood, and
5518 accepted. Now in these cases no error is raised in urllib (issue
5519 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005527- Added a timeout parameter to the constructor of other protocols
5528 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5529 work started with create_connection() and timeout in httplib, and
5530 closes patch #723312.
5531
Vinay Sajip8549ce32007-05-06 17:53:37 +00005532- Patch #1676823: Added create_connection() to socket.py, which may be
5533 called with a timeout, and use it from httplib (whose HTTPConnection

5556
Georg Brandlf66b6032007-03-14 08:27:52 +00005557- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005558 AttributeError instead of an IOError when the server's response
5559 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005560

Georg Brandl3ee81df2008-05-17 18:14:43 +00005565- Patch #1429539: pdb now correctly initializes the __main__ module
5566 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005567 correctly now.
5568

5575
Georg Brandl3ee81df2008-05-17 18:14:43 +00005576- Patch #1530482: add pydoc.render_doc() which returns the
5577 documentation for a thing instead of paging it to stdout, which

5591
Georg Brandl92a6bae2007-03-13 17:43:32 +00005592- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005593 are set for invalid interpolation sequences that would lead to
5594 errors on reading back those values.

Collin Winter22c42ba2007-03-10 02:51:26 +00005629

5637 returned string up to the first NUL character.

5648
Georg Brandl3ee81df2008-05-17 18:14:43 +00005649- unittest now verifies more of its assumptions. In particular,
5650 TestCase and TestSuite subclasses (not instances) are no longer
5651 accepted in TestSuite.addTest(). This should cause no
5652 incompatibility since it never made sense with ordinary subclasses
5653 -- the failure just occurred later, with a more cumbersome
5654 exception.

5663 given a unicode argument and os.listdir() returns unicode filenames.
5664
Georg Brandl3ee81df2008-05-17 18:14:43 +00005665- Patch #1673619: setup.py identifies extension modules it doesn't

5667 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006042- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006043 time so that opening a database previously created with the DB_DUP
6044 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6045 opens. Specifically: dictionary assignment to a DB object will
6046 replace all values for a given key when the database allows
6047 duplicate values. DB users should use DB.put(k, v) when they want
6048 to store duplicates; not DB[k] = v.

6055 characters with ASCII value less than 32. Also, it correctly quotes
6056 dots only if they occur on a single line, as opposed to the previous
6057 behavior of quoting dots if they are the second character of any
6058 line.
