363-----------------
364
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000365- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
366 start byte and the continuation byte(s) are now considered invalid, instead
367 of the number of bytes specified by the start byte.
368 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
369 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
370 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
371 Previous versions returned a single u'\ufffd'.
372
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000373- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000374 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
375 arises from the "Overriding __eq__ blocks inheritance ..." warning
376 when turned into an exception: in this case the exception simply
377 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000379- Issue #8748: Fix two issues with comparisons between complex and integer
380 objects. (1) The comparison could incorrectly return True in some cases
381 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
382 (2) The comparison raised an OverflowError for large integers, leading
383 to unpredictable exceptions when combining integers and complex objects
384 in sets or dicts.
385
Mark Dickinson81336372010-05-30 12:12:25 +0000386- Issue #5211: Implicit coercion for the complex type is now completely
387 removed. (Coercion for arithmetic operations was already removed in 2.7
388 alpha 4, but coercion for rich comparisons was accidentally left in.)
389
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000390- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

392
Georg Brandlfee0f442010-05-22 21:26:21 +0000393- Issue #7902: When using explicit relative import syntax, don't try implicit

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

955 the set of integer codes for which it was used differed between native packing
956 and standard packing.)

R. David Murrayf28fd242010-02-23 00:24:49 +00001162 is run with the -OO flag. Tests requiring docstrings are skipped.
1163
Georg Brandlba83f822010-03-14 09:50:54 +00001164- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is

Georg Brandlba83f822010-03-14 09:50:54 +00001199- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1200 and add the additional members returned in an OSVERSIONINFOEX structure. The
1201 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001204- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1205 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1206 returning NULL. The macro now returns a statically allocated empty string
1207 instead.

1217 strings,
1218 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1219 numeric strings corresponding to subnormal values,
1220 (3) a memory leak for some values large enough to cause overflow, and
1221 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001252- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001253 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001254 Also, raise ValueError rather than TypeError when an unknown TIPC address
1255 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001259- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001260 file position when calling `truncate()`. It would previously change the file
1261 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001262 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1263
Georg Brandlba83f822010-03-14 09:50:54 +00001264- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1265 class used to represent files stored inside an archive. The new
1266 implementation is significantly faster and can be wrapped in a
1267 ``io.BufferedReader`` object for more speedups. It also solves an issue
1268 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1269 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001279- Issue #7748: Since unicode values are supported for some metadata options in
1280 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1281 encoded string for them. This ensures that the upload and register commands
1282 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001359- The ``__complex__()`` method is now looked up on the class of instances to
1360 make it consistent with other special methods.

1364
Mark Dickinson1b34d252010-01-01 17:27:30 +00001365- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001366 DeprecationWarning when passed a float argument where an integer was expected.
1367 These functions and methods now raise TypeError instead. The majority of the
1368 effects of this change are in the extension modules, but some core functions
1369 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1370 and many unicode/str methods.

1384 of integers: the result of a/b is now correctly rounded for ints a and b (at
1385 least on IEEE 754 platforms), and in particular does not depend on the
1386 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001553- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1554 decimal string that's guaranteed to round back to x under correct rounding
1555 (with round-half-to-even rounding mode). Previously it gave a string based on
1556 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1557 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1558 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001560- Issue #7117: On almost all platforms: float-to-string and string-to-float
1561 conversions within Python are now correctly rounded. Places these conversions
1562 occur include: str for floats and complex numbers; the float and complex
1563 constructors; old-style and new-style numeric formatting; serialization and
1564 deserialization of floats and complex numbers using marshal, pickle and json;
1565 parsing of float and imaginary literals in Python code; Decimal-to-float
1566 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001567
Georg Brandlba83f822010-03-14 09:50:54 +00001568 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1569 providing correctly-rounded strtod and dtoa C functions. This code is
1570 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1571 the C compiler. There may be a small number of platforms on which correct
1572 operation of this code cannot be guaranteed, so the code is not used: notably,
1573 this applies to platforms where the C double format is not IEEE 754 binary64,
1574 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1575 and Python's configure script is unable to determine how to change the FPU
1576 precision. On these platforms conversions use the platform strtod and dtoa,
1577 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001579- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1580 uses the correctly-rounded string <-> float conversions described above (when
1581 available), and so produces correctly rounded results that will display nicely
1582 under the float repr. There are two related small changes: (1) round now
1583 accepts any class with an ``__index__()`` method for its second argument (but
1584 no longer accepts floats for the second argument), and (2) an excessively
1585 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1586 raises an exception.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003369- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

3371 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3372 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00003470 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3471 for catch_warnings() also led to an improvement in the raising of a
3472 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003538What's New in Python 2.6 beta 3?
3539================================
3540
Barry Warsaw07a4a382008-08-21 01:15:08 +00003541*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003542
3543Core and Builtins
3544-----------------
3545
Guido van Rossumf8402962008-08-20 15:01:50 +00003546- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3547 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3548 extensions do not automatically benefit from the class attribute
3549 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3550 to their tp_flags field if they care. This is a backwards
3551 compatibility feature; in 3.0, all types will use the cache by
3552 default.
3553
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003554- Keyword arguments can now follow starred arguments. (``f(a, *args,
3555 keyword=23)`` is now valid syntax.)
3556
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003557- ctypes function pointers that are COM methods have a boolean True
3558 value again.
3559
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003560- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3561 by denying s# to parse objects that have a releasebuffer procedure,
3562 and introducing s*.
3563
Georg Brandl1e13ea92008-08-11 09:07:59 +00003564- Issue #3537: Fix an assertion failure when an empty but presized dict
3565 object was stored in the freelist.
3566
Mark Dickinsonb6467572008-08-04 21:30:09 +00003567- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3568 ValueError consistently across platforms.
3569
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003570- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3571 (64bit Unix, for example), unichr() would truncate its argument and return
3572 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3573
Neal Norwitze7d8be82008-07-31 17:17:14 +00003574- Apply security patches from Apple.
3575
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003576- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3577 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3578
Antoine Pitrou92f82162008-07-25 22:22:08 +00003579- Issue #1819: function calls with several named parameters are now on
3580 average 35% faster (as measured by pybench).
3581
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003582- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3583 the python debugger steps into a class statement: the free variables (local
3584 variables defined in an outer scope) would be deleted from the outer scope.
3585
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003586- Issue #2620: Overflow checking when allocating or reallocating memory
3587 was not always being done properly in some python types and extension
3588 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3589 all been updated to perform better checks and places in the code that
3590 would previously leak memory on the error path when such an allocation
3591 failed have been fixed.

3594-------
3595
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003596- Issue #3612: Added some missing basic types in ctypes.wintypes.
3597
Benjamin Petersone977ad42008-08-20 01:42:01 +00003598- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3599 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3600
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003601- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3602 version reported by these tools does not necessarily follow the python
3603 version numbering scheme, so the module is less strict when parsing it.
3604
Nick Coghlanf70385a2008-08-18 12:42:46 +00003605- Issue #2235: Added Py3k warnings for types which will become unhashable
3606 under the stricter __hash__ inheritance rules in 3.0. Several types
3607 which did not meet the rules for hash invariants and were already
3608 unhashable in 3.0 have now been explicitly flagged as unhashable in
3609 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3610 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3611
Brett Cannon88f801d2008-08-18 00:46:22 +00003612- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3613 imported into the module but exposed as part of the module's API.
3614
Brett Cannon7b96f072008-08-18 00:41:11 +00003615- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3616
Brett Cannon46225e72008-08-18 00:36:52 +00003617- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003619- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3620
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003621- Issue #3575: Incremental decoder's decode function now takes bytearray
3622 by using 's*' instead of 't#'.
3623
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003624- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003625 fails unicode conversion on 2nd parameter. (windows only)
3626
Georg Brandl222e2082010-08-01 22:27:39 +00003627- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003628 in a redirect.
3629
Brett Cannonabe423e2008-08-16 21:47:07 +00003630- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003631 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003632
Facundo Batistaeb90b782008-08-16 14:44:07 +00003633- Issue #2776: fixed small issue when handling an URL with double slash
3634 after a 302 response in the case of not going through a proxy.
3635
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003636- Issue #2676: in the email package, content-type parsing was hanging on
3637 pathological input because of quadratic or exponential behaviour of a
3638 regular expression.
3639
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003640- Issue #3476: binary buffered reading through the new "io" library is now
3641 thread-safe.
3642
Brett Cannonbf3157b2008-08-14 05:00:03 +00003643- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3644 since mimetools itself is deprecated. Because modules are cached, all
3645 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3646
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003647- Issue #3134: shutil referenced undefined WindowsError symbol.
3648
Robert Schuppenies14646332008-08-10 11:01:53 +00003649- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3650 menu entries were not deleted.
3651
Brett Cannon83e81842008-08-09 23:30:55 +00003652- Copied the implementation of reduce() to _functools.reduce() to have a
3653 version that did not raise a DeprecationWarning under -3.
3654
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003655- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3656 a MemoryError rather than silently stop the iteration.
3657
Guido van Rossum59ce9012008-08-09 14:55:34 +00003658- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3659 to _sre.compile() will now be rejected. This should not affect anybody
3660 since the re.compile() function never generates invalid re-bytecode.
3661
Skip Montanaroa032bf42008-08-08 22:52:51 +00003662- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3663 upon first access it can be automatically initialized from the csv file if
3664 it wasn't initialized during instantiation.
3665
Brett Cannon3aa2a492008-08-06 22:28:09 +00003666- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3667 the reload() built-in has been removed.
3668
Brett Cannon7e30b672008-08-04 21:52:25 +00003669- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003670 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003671 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,

3673 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3674 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3675 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Antoine Pitroude781a42008-08-09 12:43:23 +00003681 asking for a specific length. This problem only affected files opened
3682 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003683
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003684- Issue #3449: Update decimal module to use most recent specification
3685 (v. 1.68) and tests (v. 2.58) from IBM.

3738-----------------
3739
Georg Brandl3e483f62008-07-16 22:57:41 +00003740- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3741 its methods now allow for items objects that can be converted to
3742 an integer using operator.index().
3743
Mark Dickinson64b7e502008-07-16 09:40:03 +00003744- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3745 produced a ValueError instead of giving the correct float.
3746
Eric Smitha5fa5a22008-07-16 00:11:49 +00003747- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3748 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3749
Mark Dickinson7103aa42008-07-15 19:08:33 +00003750- Issue #3008: the float type has a new instance method 'float.hex'
3751 and a new class method 'float.fromhex' to convert floating-point
3752 numbers to and from hexadecimal strings, respectively.
3753
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003754- Issue #2235: __hash__ is once again inherited by default. To allow
3755 collections.Hashable to remain meaningful in the presence of the
3756 default hash implementation (object.__hash__), it is now possible
3757 to explicit block inheritance of hash by setting __hash__=None at
3758 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3759 level.
3760
Nick Coghlanb028f502008-07-13 14:52:36 +00003761- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3762 the parent module cannot be found while performing an absolute import.
3763 This means that an incorrectly defined __package__ attribute will
3764 now only prevent relative imports in that module rather than causing
3765 all imports from that module to fail.
3766
Nick Coghlan14ff9942008-07-08 14:21:42 +00003767- Issue #2517: Allow unicode messages in Exceptions again by correctly

3777 another thread's dictionary.
3778
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003779- Issue #3004: Minor change to slice.indices(): the start and stop
3780 arguments are now treated identically, making the behaviour easier
3781 to describe and understand. For example, slice(None, -10,
3782 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3783 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3784 10, -1).
3785
Georg Brandl278fc502008-07-19 12:46:12 +00003786- Issue #3219: Calling a function with repeated keyword arguments,
3787 f(a=2, a=23), would not cause a syntax error. This was a regression
3788 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00003790- Issue #2862: Make int and float freelist management consistent with
3791 other freelists. Changes their CompactFreeList apis into

3798 api functions without holding the GIL, which could lead to a fatal
3799 error when they failed.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003826- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3827 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003828 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003829 content-length. The problem had been corrected in the 2.4 branch, but never
3830 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003845- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3846 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004300- Issue #1631171: Re-implement the 'warnings' module in C (the
4301 original Python code has been kept as backup). This will allow for
4302 using the 'warning's machinery in such places as the parser where
4303 use of pure Python code is not possible. Both the ``showarning()``
4304 and ``formatwarning()`` gain an optional 'line' argument which is
4305 not called by default for backwards-compatibility reasons. Setting
4306 ``warnings.showwarning()`` to an implementation that lacks support
4307 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004370- Issue #2550: The approach used by client/server code for obtaining
4371 ports to listen on in network-oriented tests has been refined in an
4372 effort to facilitate running multiple instances of the entire
4373 regression test suite in parallel without issue.
4374 test_support.bind_port() has been fixed such that it will always
4375 return a unique port -- which wasn't always the case with the
4376 previous implementation, especially if socket options had been set
4377 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4378 new implementation of bind_port() will actually raise an exception
4379 if it is passed an AF_INET/SOCK_STREAM socket with either the
4380 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4381 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4382 the socket it's been passed. This currently only applies to
4383 Windows. This option prevents any other sockets from binding to the
4384 host/port we've bound to, thus removing the possibility of the
4385 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4386 when a second SOCK_STREAM socket binds and accepts to a host/port
4387 that's already been bound by another socket. The optional preferred
4388 port parameter to bind_port() has been removed. Under no
4389 circumstances should tests be hard coding ports!
4390
4391 test_support.find_unused_port() has also been introduced, which will
4392 pass a temporary socket object to bind_port() in order to obtain an
4393 unused port. The temporary socket object is then closed and
4394 deleted, and the port is returned. This method should only be used
4395 for obtaining an unused port in order to pass to an external program
4396 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4397 a parameter to a server-oriented class that doesn't give you direct
4398 access to the underlying socket used.
4399
4400 Finally, test_support.HOST has been introduced, which should be used
4401 for the host argument of any relevant socket calls (i.e. bind and
4402 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004403
4404 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004405 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004406 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4407 test_asynchat and test_socket_ssl.
4408
Georg Brandl3ee81df2008-05-17 18:14:43 +00004409 It is now possible for multiple instances of the regression test
4410 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004689- Added the future_builtins module, which contains hex() and oct().
4690 These are the PEP 3127 version of these functions, designed to be
4691 compatible with the hex() and oct() builtins from Python 3.0. They
4692 differ slightly in their output formats from the existing, unchanged
4693 Python 2.6 builtins. The expected usage of the future_builtins
4694 module is:
4695 from future_builtins import hex, oct
4696
Eric Smith7ef40bf2008-02-20 23:34:22 +00004697- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4698 exponents for exponents with absolute value < 100. Follows C99
4699 standard. This is a change on Windows, which would use 3 digits.
4700 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4701 so that any alterations it does to the resulting string will be
4702 available in stringlib/formatter.h (for float.__format__).
4703
Eric Smith5a3c1352008-02-19 13:21:56 +00004704- Implemented PEP 3101, Advanced String Formatting. This adds a new
4705 builtin format(); a format() method for str and unicode; a
4706 __format__() method to object, str, unicode, int, long, float, and
4707 datetime; the class string.Formatter; and the C API
4708 PyObject_Format().
4709
Georg Brandl3ee81df2008-05-17 18:14:43 +00004710- Fixed several potential crashes, all caused by specially crafted
4711 __del__ methods exploiting objects in temporarily inconsistent
4712 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004755- Patch #1473257: generator objects gain a gi_code attribute. This is
4756 the same object as the func_code attribute of the function that
4757 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004758
Georg Brandl3ee81df2008-05-17 18:14:43 +00004759- Issue #1920: "while 0" statements were completely removed by the
4760 compiler, even in the presence of an "else" clause, which is
4761 supposed to be run when the condition is false. Now the compiler
4762 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004763

Christian Heimes082c9b02008-01-23 14:20:50 +00004773 several extension methods and modules do not work without unicode
4774 support.
4775
Georg Brandl26543b12008-01-21 18:36:51 +00004776- Issue #1882: when compiling code from a string, encoding cookies in the
4777 second line of code were not always recognized correctly.
4778
Georg Brandl14404b62008-01-19 19:27:05 +00004779- Issue #1679: "0x" was taken as a valid integer literal.
4780
Georg Brandl6caad7d2008-01-26 14:19:22 +00004781- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004782 added.
4783
Christian Heimesc94e2b52008-01-14 04:13:37 +00004784- sys.float_info / PyFloat_GetInfo: The floating point information
4785 object was converted from a dict to a specialized structseq object.
4786
Georg Brandl3ee81df2008-05-17 18:14:43 +00004787- Patch #1816: Added sys.flags structseq. It exposes the status of
4788 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004789
Georg Brandl3ee81df2008-05-17 18:14:43 +00004790- Objects/structseq.c: Implemented new structseq representation. The
4791 patch makes structseqs (e.g. the return value of os.stat) more
4792 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004793
Georg Brandl3ee81df2008-05-17 18:14:43 +00004794- Patch #1700288: added a type attribute cache that caches method
4795 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004796
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004797- Bug #1776: __import__() no longer accepts filenames on any platform.
4798 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004799
Georg Brandlaed6c662008-01-07 17:25:53 +00004800- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4801
Georg Brandl3ee81df2008-05-17 18:14:43 +00004802- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4803 envvar and sys.dont_write_bytecode attribute. All these can be set
4804 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004805
Georg Brandl3ee81df2008-05-17 18:14:43 +00004806- Improve some exception messages when Windows fails to load an
4807 extension module. Now we get for example '%1 is not a valid Win32
4808 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004809
Georg Brandl3ee81df2008-05-17 18:14:43 +00004810- Bug #1481296: Fixed long(float('nan')) != 0L.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004815- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004816 and INF. float("nan"), float("inf") and float("-inf") now work on
4817 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004818
Georg Brandl3ee81df2008-05-17 18:14:43 +00004819- Compiler now generates simpler and faster code for dictionary
4820 literals. The oparg for BUILD_MAP now indicates an estimated
4821 dictionary size. There is a new opcode, STORE_MAP, for adding
4822 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004832- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004833 SystemError.
4834
Nick Coghlanef01d822007-12-03 12:55:17 +00004835- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00004851- Patch #1739468: Directories and zipfiles containing a __main__.py
4852 file can now be directly executed by passing their name to the
4853 interpreter. The directory/zipfile is automatically inserted as the
4854 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004855
Georg Brandl3ee81df2008-05-17 18:14:43 +00004856- Issue #1265: Fix a problem with sys.settrace, if the tracing
4857 function uses a generator expression when at the same time the
4858 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004859
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004860- sets and frozensets now have an isdisjoint() method.
4861
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004862- optimize the performance of builtin.sum().
4863
Neal Norwitz44f326e2007-10-05 05:29:17 +00004864- Fix warnings found by the new version of the Coverity checker.
4865
Georg Brandl21e99f42010-03-07 15:23:59 +00004866- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004867 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4868 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004869
Georg Brandl3ee81df2008-05-17 18:14:43 +00004870- Issue #1686386: Tuple's tp_repr did not take into account the
4871 possibility of having a self-referential tuple, which is possible
4872 from C code. Nor did object's tp_str consider that a type's tp_str
4873 could do something that could lead to an inifinite recursion.
4874 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4875 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004876
Georg Brandl3ee81df2008-05-17 18:14:43 +00004877- Issue #1164: It was possible to trigger deadlock when using the
4878 'print' statement to write to a file since the GIL was not released
4879 as needed. Now PyObject_Print() does the right thing along with
4880 various tp_print implementations of the built-in types and those in
4881 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004882
Georg Brandl3ee81df2008-05-17 18:14:43 +00004883- Issue #1147: Exceptions were directly allowing string exceptions in
4884 their throw() method even though string exceptions no longer
4885 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004886
Georg Brandl3ee81df2008-05-17 18:14:43 +00004887- Issue #1096: Prevent a segfault from getting the repr of a very
4888 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004889
Brett Cannon1e534b52007-09-07 04:18:30 +00004890- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004891 PyObject_Call() never calling back out to Python code to trigger
4892 recursion depth updates/checks. Required the creation of a static
4893 RuntimeError instance in case normalizing an exception put the
4894 recursion check value past its limit. Fixes crashers
4895 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004896
Georg Brandl3ee81df2008-05-17 18:14:43 +00004897- Patch #1031213: Decode source line in SyntaxErrors back to its

4901 with %G.
4902
Georg Brandl3ee81df2008-05-17 18:14:43 +00004903- Prevent expandtabs() on string and unicode objects from causing a
4904 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00004905

Neal Norwitz0ac60192007-05-27 04:08:54 +00004910- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004911 __*__ attributes. (Some already existed, e.g., __doc__ and
4912 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004913
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004914- Add -3 option to the interpreter to warn about features that are
4915 deprecated and will be changed/removed in Python 3.0.
4916
Georg Brandl2134e752007-05-21 20:34:16 +00004917- Patch #1686487: you can now pass any mapping after '**' in function
4918 calls.
4919
Collin Winter62903052007-05-18 23:11:24 +00004920- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004921 "except E as target:". This is to provide forwards compatibility
4922 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004923
Brett Cannon229cee22007-05-05 01:34:02 +00004924- Deprecate BaseException.message as per PEP 352.
4925
Georg Brandl3ee81df2008-05-17 18:14:43 +00004926- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004927 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004928
Vinay Sajip8549ce32007-05-06 17:53:37 +00004929- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004930 setting a plain string, ie don't expand to single letter identifiers.
4931
Raymond Hettinger13936692007-04-11 18:40:58 +00004932- Request #1191699: Slices can now be pickled.
4933
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004934- Request #1193128: str.translate() now allows a None argument for
4935 translations that only remove characters without re-mapping the
4936 remaining characters.
4937
Georg Brandl5cb76c12007-03-21 09:00:39 +00004938- Patch #1682205: a TypeError while unpacking an iterable is no longer
4939 masked by a generic one with the message "unpack non-sequence".
4940
Neal Norwitzaa754b72007-03-21 06:39:48 +00004941- Remove unused file Python/fmod.c.
4942
Guido van Rossum143b5642007-03-23 04:58:42 +00004943- Bug #1683368: The object.__init__() and object.__new__() methods are
4944 now stricter in rejecting excess arguments. The only time when
4945 either allows excess arguments is when it is not overridden and the
4946 other one is. For backwards compatibility, when both are
4947 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004948 warning later). Also, type.__init__() insists on the same signature
4949 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004950
Georg Brandl3ee81df2008-05-17 18:14:43 +00004951- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4952 object to complex using its __complex__() method before falling back
4953 to the __float__() method. Therefore, the functions in the cmath
4954 module now can operate on objects that define a __complex__()
4955 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004956
Georg Brandl3ee81df2008-05-17 18:14:43 +00004957- Patch #1623563: allow __class__ assignment for classes with
4958 __slots__. The old and the new class are still required to have the
4959 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004960
Georg Brandl3ee81df2008-05-17 18:14:43 +00004961- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004964- Patch #1462488: Python no longer segfaults when
4965 ``object.__reduce_ex__()`` is called with an object that is faking
4966 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004967
Georg Brandl3ee81df2008-05-17 18:14:43 +00004968- Patch #1680015: Don't modify __slots__ tuple if it contains an

4972
Georg Brandl7b9c5552007-03-12 14:30:05 +00004973- Bug #1678647: write a newline after printing an exception in any
4974 case, even when converting the value to a string failed.
4975
Georg Brandl871f1bc2007-03-12 13:17:36 +00004976- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004977 its argument, if it exists. If not, it will work like before. This
4978 allows customizing the output of dir() in the presence of a
4979 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004980
Collin Winter276887b2007-03-12 16:11:39 +00004981- Patch #922167: Python no longer segfaults when faced with infinitely
4982 self-recursive reload() calls (as reported by bug #742342).
4983
Georg Brandl3ee81df2008-05-17 18:14:43 +00004984- Patch #1675981: remove unreachable code from ``type.__new__()``
4985 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004987- Patch #1491866: change the complex() constructor to allow
4988 parthensized forms. This means complex(repr(x)) now works instead of
4989 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004990
Georg Brandlaa2321b2007-03-07 00:40:28 +00004991- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004992 makes the filenames the warning module prints much more sensible
4993 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004994
Georg Brandl49aafc92007-03-07 00:34:46 +00004995- Variant of patch #697613: don't exit the interpreter on a SystemExit
4996 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004997 variable is given, but break into the interactive interpreter just
4998 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005003- Bug #1674503: close the file opened by execfile() in an error
5004 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005005
Georg Brandl0fca97a2007-03-05 22:28:08 +00005006- Patch #1674228: when assigning a slice (old-style), check for the
5007 sq_ass_slice instead of the sq_slice slot.
5008
Georg Brandl3ee81df2008-05-17 18:14:43 +00005009- When printing an unraisable error, don't print exceptions. before
5010 the name. This duplicates the behavior whening normally printing

Facundo Batistad918a652007-04-24 13:54:38 +00005502- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005503 the client's request was successfully received, understood, and
5504 accepted. Now in these cases no error is raised in urllib (issue
5505 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005513- Added a timeout parameter to the constructor of other protocols
5514 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5515 work started with create_connection() and timeout in httplib, and
5516 closes patch #723312.
5517
Vinay Sajip8549ce32007-05-06 17:53:37 +00005518- Patch #1676823: Added create_connection() to socket.py, which may be
5519 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00005520 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00005521
Martin v. Löwis0af33882007-03-23 13:27:15 +00005522- Bug #978833: Revert r50844, as it broke _socketobject.dup.

5542
Georg Brandlf66b6032007-03-14 08:27:52 +00005543- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005544 AttributeError instead of an IOError when the server's response
5545 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005546
Georg Brandl3ee81df2008-05-17 18:14:43 +00005547- Patch #957650: "%var%" environment variable references are now
5548 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00005551- Patch #1429539: pdb now correctly initializes the __main__ module
5552 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005553 correctly now.
5554

Georg Brandl3ee81df2008-05-17 18:14:43 +00005562- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00005575- Patch #1581073: add a flag to textwrap that prevents the dropping of
5576 whitespace while wrapping.
5577
Georg Brandl92a6bae2007-03-13 17:43:32 +00005578- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005579 are set for invalid interpolation sequences that would lead to
5580 errors on reading back those values.

5623 returned string up to the first NUL character.
5624

5634
Georg Brandl3ee81df2008-05-17 18:14:43 +00005635- unittest now verifies more of its assumptions. In particular,
5636 TestCase and TestSuite subclasses (not instances) are no longer
5637 accepted in TestSuite.addTest(). This should cause no
5638 incompatibility since it never made sense with ordinary subclasses
5639 -- the failure just occurred later, with a more cumbersome
5640 exception.

5649 given a unicode argument and os.listdir() returns unicode filenames.
5650
Georg Brandl3ee81df2008-05-17 18:14:43 +00005651- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006029 time so that opening a database previously created with the DB_DUP
6030 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6031 opens. Specifically: dictionary assignment to a DB object will
6032 replace all values for a given key when the database allows
6033 duplicate values. DB users should use DB.put(k, v) when they want
6034 to store duplicates; not DB[k] = v.

6041 characters with ASCII value less than 32. Also, it correctly quotes
6042 dots only if they occur on a single line, as opposed to the previous
6043 behavior of quoting dots if they are the second character of any
6044 line.
