Nadeem Vawda6cad3712012-11-05 00:55:06 +01001443 successive calls after EOF in unused_data, instead of only saving the argument
Nadeem Vawda252f4dc2012-11-11 02:14:15 +01001444 to the last call. decompressobj().flush() now correctly sets unused_data and
1445 unconsumed_tail. A bug in the handling of MemoryError when setting the
1446 unconsumed_tail attribute has also been fixed. Patch by Serhiy Storchaka.

Ned Deily18fae3f2013-01-31 01:24:55 -08001768- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1769 In particular, fix extension module build failures when trying to use
1770 32-bit-only installer Pythons on systems with Xcode 4 (currently
1771 OS X 10.8, 10.7, and optionally 10.6).
1772 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1773 * Since Xcode 4 removes ppc support, extension module builds now
1774 check for ppc compiler support and by default remove ppc and
1775 ppc64 archs when they are not available.
1776 * Extension module builds now revert to using system installed
1777 headers and libs (/usr and /System/Library) if the SDK used
1778 to build the interpreter is not installed or has moved.
1779 * Try to avoid building extension modules with deprecated
1780 and problematic Apple llvm-gcc compiler. If original compiler
1781 is not available, use clang instead by default.

2133 int.__pow__. These overflow checks were causing int.__pow__ to produce
2134 incorrect results with recent versions of Clang, as a result of the

2136 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01002206 has left two versions of customize_compiler, the original in
2207 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002212- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2213 Distutils-based packages with C extension modules may fail because
2214 Apple has removed gcc-4.2, the version used to build python.org
2215 64-bit/32-bit Pythons. If the user does not explicitly override
2216 the default C compiler by setting the CC environment variable,
2217 Distutils will now attempt to compile extension modules with clang
2218 if gcc-4.2 is required but not found. Also as a convenience, if
2219 the user does explicitly set CC, substitute its value as the default
2220 compiler in the Distutils LDSHARED configuration variable for OS X.
2221 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2222 SDK, neither of which are available in Xcode 4. This change does not
2223 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002473- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2474 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2475 interpreter process. This could cause failures in non-Distutils subprocesses
2476 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002477 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002478 deployment target only in the environment of each build subprocess. It is
2479 still possible to globally override the default by setting
2480 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2481 greater or equal to the default value, the value with which the interpreter
2482 was built.

2512 the ticker doesn't have to wind down to zero from the old starting point
2513 before the new interval takes effect. And if the user increases the
2514 interval, it makes sure the new limit takes effect right away rather have an
2515 early task switch before recognizing the new interval.

3479 handles non-blocking readinto() returning None correctly.
3480
Antoine Pitrouf7f390a2010-09-14 14:37:18 +00003481- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
3482 SSLSocket.sendto() to match the corresponding socket methods. Also,
3483 fix various SSLSocket methods to raise socket.error rather than an
3484 unhelpful TypeError when called on an unconnected socket. Original patch
3485 by Andrew Bennetts.

3494
Raymond Hettinger20397532010-09-12 02:11:45 +00003495- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3496 This prevents user-created self-referencing ordered dictionaries from
3497 becoming permanently uncollectable GC garbage. The downside is that
3498 removing __del__ means that the internal doubly-linked list has to wait for
3499 GC collection rather than freeing memory immediately when the refcnt drops
3500 to zero.
3501
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003502- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3505
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003506- Issue #9792: In case of connection failure, socket.create_connection()
3507 would swallow the exception and raise a new one, making it impossible
3508 to fetch the original errno, or to filter timeout errors. Now the
3509 original error is re-raised.
3510
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003511- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

3513 be updated back after the system call. Original patch by Brian Brazil.

3520
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003521- Issue #808164: Fixed socket.close to avoid references to globals, to

3525 can be set to False to turn off the previously undocumented 'popularity'
3526 heuristic. Patch by Terry Reedy and Eli Bendersky
3527

3529 falling into recursion.
3530
R. David Murray7c4bf552010-08-25 01:45:57 +00003531- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3532 character years even if the message contains RFC822 two character years.
3533
Daniel Stutzbach91287322010-08-24 21:09:30 +00003534- Issue #8750: Fixed MutableSet's methods to correctly handle

3546 module now correctly return a set. (Patch by Eli Bendersky.)
3547
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003548- Issue #9617: Signals received during a low-level write operation aren't
3549 ignored by the buffered IO layer anymore.
3550
Benjamin Peterson52c36052010-08-21 03:03:22 +00003551- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3552 are not held onto after they are deleted elsewhere.
3553
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003554- Issue #9626: the view methods for collections.OrderedDict() were returning

3560 without this marker will not be overwritten or removed.
3561
Antoine Pitroue1436d12010-08-12 15:25:51 +00003562- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3563 and a BadZipfile error is raised if it doesn't match (as used to be the
3564 case in Python 2.5 and earlier).
3565
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003566- Issue #9550: a BufferedReader could issue an additional read when the
3567 original read request had been satisfied, which could block indefinitely
3568 when the underlying raw IO channel was e.g. a socket. Report and original
3569 patch by Jason V. Miller.
3570
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003571- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00003589- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
3590 This is how it is supposed to work, wget and curl do the same. Previous
3591 behavior was wrong.

3599 the option character for the added 'h/help' option if prefix_chars
3600 does not contain a '-', instead of raising an error.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003958- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3959 start byte and the continuation byte(s) are now considered invalid, instead

3961 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3962 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3963 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3974 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004319 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4320 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4321 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4342-----------------
4343
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004344- Issue #7301: Add environment variable $PYTHONWARNINGS.
4345
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004346- Issue #8329: Don't return the same lists from select.select when no fds are
4347 changed.
4348
Georg Brandlfee0f442010-05-22 21:26:21 +00004349- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004350 on 64-bit machines. The shift count for either left or right shift is
4351 permitted to be up to sys.maxsize.
4352
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004353- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004357- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4358
Georg Brandlfee0f442010-05-22 21:26:21 +00004359- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4360 with a non-empty format string. This is an effort to future-proof user
4361 code. If a derived class does not currently implement __format__ but later
4362 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004363 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004364 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004365

Victor Stinner66644262010-03-10 22:30:19 +00004379- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004380 (SIGINT). If an error occurs while importing the site module, the error is

4396
Georg Brandlfee0f442010-05-22 21:26:21 +00004397- Issue #8257: The Decimal construct now accepts a float instance directly,
4398 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004399
4400 >>> Decimal(1.1)
4401 Decimal('1.100000000000000088817841970012523233890533447265625')
4402
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004403- collections.Counter() now supports a subtract() method.
4404
Georg Brandlfee0f442010-05-22 21:26:21 +00004405- The functools module now has a total_ordering() class decorator to simplify
4406 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004408- The functools module also adds cmp_to_key() as a tool to transition old-style
4409 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004410
Georg Brandlfee0f442010-05-22 21:26:21 +00004411- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4412 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004413
Georg Brandlfee0f442010-05-22 21:26:21 +00004414- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4415 InvalidOperation instead of returning False. (Comparisons involving a quiet
4416 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4417 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004418
Georg Brandlfee0f442010-05-22 21:26:21 +00004419- Issue #2531: Comparison operations between floats and Decimal instances now
4420 return a result based on the numeric values of the operands; previously they
4421 returned an arbitrary result based on the relative ordering of id(float) and
4422 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004423
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004424- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004425 argument `-` which tells it to read files to compile from stdin. Each line is
4426 read on demand and the named file is compiled immediately. (Original patch by
4427 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004428
Georg Brandlfee0f442010-05-22 21:26:21 +00004429- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00004432- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4433 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004434 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004435
Georg Brandlfee0f442010-05-22 21:26:21 +00004436- Comparisons using one of <, <=, >, >= between a complex instance and a
4437 Fractions instance now raise TypeError instead of returning True/False. This
4438 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4439 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004440

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004450- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004451 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4452 silenced.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004538- Issue #8300: When passing a non-integer argument to struct.pack with any
4539 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00004543- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4544 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4545 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004546 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4547 inconsistent: __int__ was used for some integer codes but not for others, and
4548 the set of integer codes for which it was used differed between native packing
4549 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004761- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4762 now also used by regrtest to run all the tests in a temporary directory. The
4763 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4764 Xicluna who helped with the patch.

4781 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004782 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00004801- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4802 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4803 returning NULL. The macro now returns a statically allocated empty string
4804 instead.

4814 strings,
4815 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4816 numeric strings corresponding to subnormal values,
4817 (3) a memory leak for some values large enough to cause overflow, and
4818 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00004850 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004856- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004857 file position when calling `truncate()`. It would previously change the file
4858 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004859 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4860
Georg Brandlba83f822010-03-14 09:50:54 +00004861- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4862 class used to represent files stored inside an archive. The new
4863 implementation is significantly faster and can be wrapped in a
4864 ``io.BufferedReader`` object for more speedups. It also solves an issue
4865 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4866 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004876- Issue #7748: Since unicode values are supported for some metadata options in
4877 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4878 encoded string for them. This ensures that the upload and register commands
4879 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004956- The ``__complex__()`` method is now looked up on the class of instances to
4957 make it consistent with other special methods.

4964 These functions and methods now raise TypeError instead. The majority of the
4965 effects of this change are in the extension modules, but some core functions
4966 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4967 and many unicode/str methods.

4983 internal representation of a long.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005148
Georg Brandlba83f822010-03-14 09:50:54 +00005149- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5150 decimal string that's guaranteed to round back to x under correct rounding
5151 (with round-half-to-even rounding mode). Previously it gave a string based on
5152 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5153 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5154 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005155
Georg Brandlba83f822010-03-14 09:50:54 +00005156- Issue #7117: On almost all platforms: float-to-string and string-to-float
5157 conversions within Python are now correctly rounded. Places these conversions
5158 occur include: str for floats and complex numbers; the float and complex
5159 constructors; old-style and new-style numeric formatting; serialization and
5160 deserialization of floats and complex numbers using marshal, pickle and json;
5161 parsing of float and imaginary literals in Python code; Decimal-to-float
5162 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005163
Georg Brandlba83f822010-03-14 09:50:54 +00005164 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5165 providing correctly-rounded strtod and dtoa C functions. This code is
5166 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5167 the C compiler. There may be a small number of platforms on which correct
5168 operation of this code cannot be guaranteed, so the code is not used: notably,
5169 this applies to platforms where the C double format is not IEEE 754 binary64,
5170 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5171 and Python's configure script is unable to determine how to change the FPU
5172 precision. On these platforms conversions use the platform strtod and dtoa,
5173 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005174
Georg Brandlba83f822010-03-14 09:50:54 +00005175- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5176 uses the correctly-rounded string <-> float conversions described above (when
5177 available), and so produces correctly rounded results that will display nicely
5178 under the float repr. There are two related small changes: (1) round now
5179 accepts any class with an ``__index__()`` method for its second argument (but
5180 no longer accepts floats for the second argument), and (2) an excessively
5181 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5182 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005329- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5330 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5331 but with at least one decimal point and with a default precision
5332 of 12. Previously, the behavior the same but with a default precision of 6.
5333 This more closely matches ``str()``, and reduces surprises when adding
5334 alignment flags to the empty presentation type. This also affects the new
5335 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00005475- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5476 existing .py counterpart, override the co_filename attributes of all code

5532
Georg Brandlba83f822010-03-14 09:50:54 +00005533- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5534 file objects with closefd=False. The file descriptor is still kept open but
5535 the file object behaves like a closed file. The ``FileIO`` object also got a
5536 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00005559- On windows, ``os.chdir()`` given unicode was not working if
5560 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5561 this code path is really executed because I cannot move to such directory on
5562 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005564- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5565 element is temporarily replaced with an equivalent frozenset. But the
5566 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00005587- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5588 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5589 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5590 of using the replace error handler in PyUnicode_DecodeUTF8().
5591
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005592- Issue #3739: The unicode-internal encoder now reports the number of characters

5594
Georg Brandlba83f822010-03-14 09:50:54 +00005595- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5597 gives improved memory leak detection when running under Valgrind, while taking
5598 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00006845 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006968- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6969 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6970 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6971 ``printf`` function, whereas PyString_FromFormat has an independent
6972 implementation and uses "%zd" on all platforms for size_t values.
6973 This makes a difference on win64, where ``printf`` needs "%Id" to display
6974 64bit values.

6980 object; previously an int would be returned for small values. the __long__
6981 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006991 was correctly parsed but parsing of subsequent arguments failed.
6992
Vinay Sajip35e3b032008-09-01 14:33:59 +00006993- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006994 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6995 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6997 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6998 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007137What's New in Python 2.6 beta 3?
7138================================
7139
Barry Warsaw07a4a382008-08-21 01:15:08 +00007140*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007141
7142Core and Builtins
7143-----------------
7144
Guido van Rossumf8402962008-08-20 15:01:50 +00007145- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7146 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7147 extensions do not automatically benefit from the class attribute
7148 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7149 to their tp_flags field if they care. This is a backwards
7150 compatibility feature; in 3.0, all types will use the cache by
7151 default.
7152
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007153- Keyword arguments can now follow starred arguments. (``f(a, *args,
7154 keyword=23)`` is now valid syntax.)
7155
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007156- ctypes function pointers that are COM methods have a boolean True
7157 value again.
7158
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007159- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7160 by denying s# to parse objects that have a releasebuffer procedure,
7161 and introducing s*.
7162
Georg Brandl1e13ea92008-08-11 09:07:59 +00007163- Issue #3537: Fix an assertion failure when an empty but presized dict
7164 object was stored in the freelist.
7165
Mark Dickinsonb6467572008-08-04 21:30:09 +00007166- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7167 ValueError consistently across platforms.
7168
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007169- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7170 (64bit Unix, for example), unichr() would truncate its argument and return
7171 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7172
Neal Norwitze7d8be82008-07-31 17:17:14 +00007173- Apply security patches from Apple.
7174
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007175- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7176 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7177
Antoine Pitrou92f82162008-07-25 22:22:08 +00007178- Issue #1819: function calls with several named parameters are now on
7179 average 35% faster (as measured by pybench).
7180
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007181- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7182 the python debugger steps into a class statement: the free variables (local
7183 variables defined in an outer scope) would be deleted from the outer scope.
7184
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007185- Issue #2620: Overflow checking when allocating or reallocating memory
7186 was not always being done properly in some python types and extension
7187 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7188 all been updated to perform better checks and places in the code that
7189 would previously leak memory on the error path when such an allocation
7190 failed have been fixed.
7191
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007192Library
7193-------
7194
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007195- Issue #3612: Added some missing basic types in ctypes.wintypes.
7196
Benjamin Petersone977ad42008-08-20 01:42:01 +00007197- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7198 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7199
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007200- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7201 version reported by these tools does not necessarily follow the python
7202 version numbering scheme, so the module is less strict when parsing it.
7203
Nick Coghlanf70385a2008-08-18 12:42:46 +00007204- Issue #2235: Added Py3k warnings for types which will become unhashable
7205 under the stricter __hash__ inheritance rules in 3.0. Several types
7206 which did not meet the rules for hash invariants and were already
7207 unhashable in 3.0 have now been explicitly flagged as unhashable in
7208 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7209 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7210
Brett Cannon88f801d2008-08-18 00:46:22 +00007211- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7212 imported into the module but exposed as part of the module's API.
7213
Brett Cannon7b96f072008-08-18 00:41:11 +00007214- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7215
Brett Cannon46225e72008-08-18 00:36:52 +00007216- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7217
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007218- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7219
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007220- Issue #3575: Incremental decoder's decode function now takes bytearray
7221 by using 's*' instead of 't#'.
7222
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007223- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007224 fails unicode conversion on 2nd parameter. (windows only)
7225
Georg Brandl222e2082010-08-01 22:27:39 +00007226- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007227 in a redirect.
7228
Brett Cannonabe423e2008-08-16 21:47:07 +00007229- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007230 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007231
Facundo Batistaeb90b782008-08-16 14:44:07 +00007232- Issue #2776: fixed small issue when handling an URL with double slash
7233 after a 302 response in the case of not going through a proxy.
7234
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007235- Issue #2676: in the email package, content-type parsing was hanging on
7236 pathological input because of quadratic or exponential behaviour of a
7237 regular expression.
7238
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007239- Issue #3476: binary buffered reading through the new "io" library is now
7240 thread-safe.
7241
Brett Cannonbf3157b2008-08-14 05:00:03 +00007242- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7243 since mimetools itself is deprecated. Because modules are cached, all
7244 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7245
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007246- Issue #3134: shutil referenced undefined WindowsError symbol.
7247
Robert Schuppenies14646332008-08-10 11:01:53 +00007248- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7249 menu entries were not deleted.
7250
Brett Cannon83e81842008-08-09 23:30:55 +00007251- Copied the implementation of reduce() to _functools.reduce() to have a
7252 version that did not raise a DeprecationWarning under -3.
7253
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007254- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7255 a MemoryError rather than silently stop the iteration.
7256
Guido van Rossum59ce9012008-08-09 14:55:34 +00007257- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7258 to _sre.compile() will now be rejected. This should not affect anybody
7259 since the re.compile() function never generates invalid re-bytecode.
7260
Skip Montanaroa032bf42008-08-08 22:52:51 +00007261- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7262 upon first access it can be automatically initialized from the csv file if
7263 it wasn't initialized during instantiation.
7264
Brett Cannon3aa2a492008-08-06 22:28:09 +00007265- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7266 the reload() built-in has been removed.
7267
Brett Cannon7e30b672008-08-04 21:52:25 +00007268- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007269 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00007270 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
7271 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
7272 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
7273 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
7274 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007275
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007276- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7277 raised an AttributeError.
7278
Benjamin Peterson01a24322008-07-28 23:35:27 +00007279- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007280 asking for a specific length. This problem only affected files opened
7281 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007282
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007283- Issue #3449: Update decimal module to use most recent specification
7284 (v. 1.68) and tests (v. 2.58) from IBM.
7285
Georg Brandl222e2082010-08-01 22:27:39 +00007286- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007287

7290
Georg Brandlf9efabb2008-07-23 15:16:45 +00007291- Deprecate the "ast" parser function aliases.
7292
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007293- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7294
7295- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7296 invalid arguments.
7297
7298- Issue #3302: Fix several crashes when calling locale's gettext functions
7299 with None arguments.
7300
7301- Issue #3389: Allow resolving dotted names for handlers in logging
7302 configuration files.
7303
7304- Deprecate the sunaudio module for removal in Python 3.0.
7305
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007306- Issue #3394: zipfile.writestr sets external attributes when passed a
7307 file name rather than a ZipInfo instance, so files are extracted with
7308 mode 0600 rather than 000 under Unix.
7309
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007310- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7311 argument in python 2.5, this broke code that subclassed Popen to include its
7312 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7321
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007322- Issue #2235: the C API function PyObject_HashNotImplemented and its
7323 interaction with the tp_hash slot (added in 2.6b2) are now documented
7324
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007325- Issue #643841: The language reference now provides more detailed
7326 coverage of the lookup process for special methods. The disclaimers
7327 regarding lack of coverage of new-style classes have also been
7328 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007331What's New in Python 2.6 beta 2?
7332================================
7333
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007334*Release date: 17-Jul-2008*
7335
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007336Core and Builtins
7337-----------------
7338
Georg Brandl3e483f62008-07-16 22:57:41 +00007339- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7340 its methods now allow for items objects that can be converted to
7341 an integer using operator.index().
7342
Mark Dickinson64b7e502008-07-16 09:40:03 +00007343- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7344 produced a ValueError instead of giving the correct float.
7345
Eric Smitha5fa5a22008-07-16 00:11:49 +00007346- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7347 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7348
Mark Dickinson7103aa42008-07-15 19:08:33 +00007349- Issue #3008: the float type has a new instance method 'float.hex'
7350 and a new class method 'float.fromhex' to convert floating-point
7351 numbers to and from hexadecimal strings, respectively.
7352
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007353- Issue #2235: __hash__ is once again inherited by default. To allow
7354 collections.Hashable to remain meaningful in the presence of the
7355 default hash implementation (object.__hash__), it is now possible
7356 to explicit block inheritance of hash by setting __hash__=None at
7357 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7358 level.
7359
Nick Coghlanb028f502008-07-13 14:52:36 +00007360- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7361 the parent module cannot be found while performing an absolute import.
7362 This means that an incorrectly defined __package__ attribute will
7363 now only prevent relative imports in that module rather than causing
7364 all imports from that module to fail.
7365
Nick Coghlan14ff9942008-07-08 14:21:42 +00007366- Issue #2517: Allow unicode messages in Exceptions again by correctly
7367 bypassing the instance dictionary when looking up __unicode__ on
7368 new-style classes.
7369
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007370- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7371 set to a custom object whose write() method happens to install
7372 another file in sys.stdout.
7373
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007374- Issue #3088: Corrected a race condition in classes derived from
7375 threading.local: the first member set by a thread could be saved in
7376 another thread's dictionary.
7377
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007378- Issue #3004: Minor change to slice.indices(): the start and stop
7379 arguments are now treated identically, making the behaviour easier
7380 to describe and understand. For example, slice(None, -10,
7381 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7382 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7383 10, -1).
7384
Georg Brandl278fc502008-07-19 12:46:12 +00007385- Issue #3219: Calling a function with repeated keyword arguments,
7386 f(a=2, a=23), would not cause a syntax error. This was a regression
7387 from 2.4 caused by the switch to the new compiler.

7397 api functions without holding the GIL, which could lead to a fatal
7398 error when they failed.
7399
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007400- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7834 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007835 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007836
7837 This is controlled by the configure argument ``--with-universal-archs``:
7838
7839 - ``--with-universal-archs=all``: install 4-way universal
7840
7841 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7842
7843 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7844
7845 This option should be used in combination with ``--enable-universalsdk=``.
7846
7847 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007896- Issue #1631171: Re-implement the 'warnings' module in C (the
7897 original Python code has been kept as backup). This will allow for
7898 using the 'warning's machinery in such places as the parser where
7899 use of pure Python code is not possible. Both the ``showarning()``
7900 and ``formatwarning()`` gain an optional 'line' argument which is
7901 not called by default for backwards-compatibility reasons. Setting
7902 ``warnings.showwarning()`` to an implementation that lacks support
7903 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007928- The getpass module has been improved on Unix. It now uses /dev/tty
7929 by default and uses stderr instead of stdout. A GetPassWarning is
7930 issued when input echo cannot be controlled.

7956 Modules/_ctypes/libffi/configure.ac.
7957
Georg Brandl3ee81df2008-05-17 18:14:43 +00007958- Issue #2385: distutils.core.run_script() makes __file__ available,
7959 so the controlled environment will more closely mirror the typical
7960 script environment. This supports setup.py scripts that refer to
7961 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007966- Issue #2550: The approach used by client/server code for obtaining
7967 ports to listen on in network-oriented tests has been refined in an
7968 effort to facilitate running multiple instances of the entire
7969 regression test suite in parallel without issue.
7970 test_support.bind_port() has been fixed such that it will always
7971 return a unique port -- which wasn't always the case with the
7972 previous implementation, especially if socket options had been set
7973 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7974 new implementation of bind_port() will actually raise an exception
7975 if it is passed an AF_INET/SOCK_STREAM socket with either the
7976 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7977 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7978 the socket it's been passed. This currently only applies to
7979 Windows. This option prevents any other sockets from binding to the
7980 host/port we've bound to, thus removing the possibility of the
7981 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7982 when a second SOCK_STREAM socket binds and accepts to a host/port
7983 that's already been bound by another socket. The optional preferred
7984 port parameter to bind_port() has been removed. Under no
7985 circumstances should tests be hard coding ports!
7986
7987 test_support.find_unused_port() has also been introduced, which will
7988 pass a temporary socket object to bind_port() in order to obtain an
7989 unused port. The temporary socket object is then closed and
7990 deleted, and the port is returned. This method should only be used
7991 for obtaining an unused port in order to pass to an external program
7992 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7993 a parameter to a server-oriented class that doesn't give you direct
7994 access to the underlying socket used.
7995
7996 Finally, test_support.HOST has been introduced, which should be used
7997 for the host argument of any relevant socket calls (i.e. bind and
7998 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007999
8000 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008001 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008002 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8003 test_asynchat and test_socket_ssl.
8004
Georg Brandl3ee81df2008-05-17 18:14:43 +00008005 It is now possible for multiple instances of the regression test
8006 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008285- Added the future_builtins module, which contains hex() and oct().
8286 These are the PEP 3127 version of these functions, designed to be
8287 compatible with the hex() and oct() builtins from Python 3.0. They
8288 differ slightly in their output formats from the existing, unchanged
8289 Python 2.6 builtins. The expected usage of the future_builtins
8290 module is:
8291 from future_builtins import hex, oct
8292
Eric Smith7ef40bf2008-02-20 23:34:22 +00008293- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8294 exponents for exponents with absolute value < 100. Follows C99
8295 standard. This is a change on Windows, which would use 3 digits.
8296 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8297 so that any alterations it does to the resulting string will be
8298 available in stringlib/formatter.h (for float.__format__).
8299
Eric Smith5a3c1352008-02-19 13:21:56 +00008300- Implemented PEP 3101, Advanced String Formatting. This adds a new
8301 builtin format(); a format() method for str and unicode; a
8302 __format__() method to object, str, unicode, int, long, float, and
8303 datetime; the class string.Formatter; and the C API
8304 PyObject_Format().
8305
Georg Brandl3ee81df2008-05-17 18:14:43 +00008306- Fixed several potential crashes, all caused by specially crafted
8307 __del__ methods exploiting objects in temporarily inconsistent
8308 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008309
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008310- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008311 prevent a possible crash: an Abstract Base Class would try to access
8312 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008313

Georg Brandl3ee81df2008-05-17 18:14:43 +00008317- Clear all free lists during a gc.collect() of the highest generation
8318 in order to allow pymalloc to free more arenas. Python may give back
8319 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008320
Georg Brandl3ee81df2008-05-17 18:14:43 +00008321- Issue #2045: Fix an infinite recursion triggered when printing a
8322 subclass of collections.defaultdict, if its default_factory is set
8323 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008324
Christian Heimesf75dbef2008-02-08 00:11:31 +00008325- Fixed a minor memory leak in dictobject.c. The content of the free
8326 list was not freed on interpreter shutdown.
8327
Georg Brandl21e99f42010-03-07 15:23:59 +00008328- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008329 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008330
Georg Brandl3ee81df2008-05-17 18:14:43 +00008331- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8332 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008333 to compact the internal free lists of pre-allocted ints and floats.
8334
Georg Brandl3ee81df2008-05-17 18:14:43 +00008335- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8336 calls. Python expected the return type int but the fork familie
8337 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008338
Georg Brandl3ee81df2008-05-17 18:14:43 +00008339- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008351- Patch #1473257: generator objects gain a gi_code attribute. This is
8352 the same object as the func_code attribute of the function that
8353 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008354
Georg Brandl3ee81df2008-05-17 18:14:43 +00008355- Issue #1920: "while 0" statements were completely removed by the
8356 compiler, even in the presence of an "else" clause, which is
8357 supposed to be run when the condition is false. Now the compiler
8358 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008359
Guido van Rossumeead05f2008-01-24 18:21:02 +00008360- A few crashers fixed: weakref_in_del.py (issue #1377858);
8361 loosing_dict_ref.py (issue #1303614, test67.py);
8362 borrowed_ref_[34].py (not in tracker).
8363
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008364- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008365 suppressed while an extension is loaded by calling SetErrorMode in
8366 dynload_win.c. The error is still reported properly.
8367
Georg Brandl3ee81df2008-05-17 18:14:43 +00008368- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008369 several extension methods and modules do not work without unicode
8370 support.
8371
Georg Brandl26543b12008-01-21 18:36:51 +00008372- Issue #1882: when compiling code from a string, encoding cookies in the
8373 second line of code were not always recognized correctly.
8374
Georg Brandl14404b62008-01-19 19:27:05 +00008375- Issue #1679: "0x" was taken as a valid integer literal.
8376
Georg Brandl6caad7d2008-01-26 14:19:22 +00008377- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008378 added.
8379
Christian Heimesc94e2b52008-01-14 04:13:37 +00008380- sys.float_info / PyFloat_GetInfo: The floating point information
8381 object was converted from a dict to a specialized structseq object.
8382
Georg Brandl3ee81df2008-05-17 18:14:43 +00008383- Patch #1816: Added sys.flags structseq. It exposes the status of
8384 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008385
Georg Brandl3ee81df2008-05-17 18:14:43 +00008386- Objects/structseq.c: Implemented new structseq representation. The
8387 patch makes structseqs (e.g. the return value of os.stat) more
8388 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008389
Georg Brandl3ee81df2008-05-17 18:14:43 +00008390- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00008412 and INF. float("nan"), float("inf") and float("-inf") now work on
8413 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008414
Georg Brandl3ee81df2008-05-17 18:14:43 +00008415- Compiler now generates simpler and faster code for dictionary
8416 literals. The oparg for BUILD_MAP now indicates an estimated
8417 dictionary size. There is a new opcode, STORE_MAP, for adding
8418 entries to the dictionary.

Neal Norwitz44f326e2007-10-05 05:29:17 +00008460- Fix warnings found by the new version of the Coverity checker.
8461
Georg Brandl21e99f42010-03-07 15:23:59 +00008462- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008463 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8464 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008465
Georg Brandl3ee81df2008-05-17 18:14:43 +00008466- Issue #1686386: Tuple's tp_repr did not take into account the
8467 possibility of having a self-referential tuple, which is possible
8468 from C code. Nor did object's tp_str consider that a type's tp_str
8469 could do something that could lead to an inifinite recursion.
8470 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8471 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008472
Georg Brandl3ee81df2008-05-17 18:14:43 +00008473- Issue #1164: It was possible to trigger deadlock when using the
8474 'print' statement to write to a file since the GIL was not released
8475 as needed. Now PyObject_Print() does the right thing along with
8476 various tp_print implementations of the built-in types and those in
8477 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008478
Georg Brandl3ee81df2008-05-17 18:14:43 +00008479- Issue #1147: Exceptions were directly allowing string exceptions in
8480 their throw() method even though string exceptions no longer
8481 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008482
Georg Brandl3ee81df2008-05-17 18:14:43 +00008483- Issue #1096: Prevent a segfault from getting the repr of a very
8484 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008485
Brett Cannon1e534b52007-09-07 04:18:30 +00008486- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008487 PyObject_Call() never calling back out to Python code to trigger
8488 recursion depth updates/checks. Required the creation of a static
8489 RuntimeError instance in case normalizing an exception put the
8490 recursion check value past its limit. Fixes crashers
8491 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008492
Georg Brandl3ee81df2008-05-17 18:14:43 +00008493- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008506- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008507 __*__ attributes. (Some already existed, e.g., __doc__ and
8508 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008509
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008510- Add -3 option to the interpreter to warn about features that are
8511 deprecated and will be changed/removed in Python 3.0.
8512
Georg Brandl2134e752007-05-21 20:34:16 +00008513- Patch #1686487: you can now pass any mapping after '**' in function
8514 calls.
8515
Collin Winter62903052007-05-18 23:11:24 +00008516- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008517 "except E as target:". This is to provide forwards compatibility
8518 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008519
Brett Cannon229cee22007-05-05 01:34:02 +00008520- Deprecate BaseException.message as per PEP 352.
8521
Georg Brandl3ee81df2008-05-17 18:14:43 +00008522- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008523 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008524
Vinay Sajip8549ce32007-05-06 17:53:37 +00008525- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008526 setting a plain string, ie don't expand to single letter identifiers.
8527
Raymond Hettinger13936692007-04-11 18:40:58 +00008528- Request #1191699: Slices can now be pickled.
8529
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008530- Request #1193128: str.translate() now allows a None argument for
8531 translations that only remove characters without re-mapping the
8532 remaining characters.
8533
Georg Brandl5cb76c12007-03-21 09:00:39 +00008534- Patch #1682205: a TypeError while unpacking an iterable is no longer

8538
Guido van Rossum143b5642007-03-23 04:58:42 +00008539- Bug #1683368: The object.__init__() and object.__new__() methods are
8540 now stricter in rejecting excess arguments. The only time when
8541 either allows excess arguments is when it is not overridden and the
8542 other one is. For backwards compatibility, when both are
8543 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008544 warning later). Also, type.__init__() insists on the same signature
8545 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008546
Georg Brandl3ee81df2008-05-17 18:14:43 +00008547- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8548 object to complex using its __complex__() method before falling back
8549 to the __float__() method. Therefore, the functions in the cmath
8550 module now can operate on objects that define a __complex__()
8551 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008552
Georg Brandl3ee81df2008-05-17 18:14:43 +00008553- Patch #1623563: allow __class__ assignment for classes with
8554 __slots__. The old and the new class are still required to have the
8555 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008556

8561 ``object.__reduce_ex__()`` is called with an object that is faking
8562 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008563
Georg Brandl3ee81df2008-05-17 18:14:43 +00008564- Patch #1680015: Don't modify __slots__ tuple if it contains an

8568
Georg Brandl7b9c5552007-03-12 14:30:05 +00008569- Bug #1678647: write a newline after printing an exception in any
8570 case, even when converting the value to a string failed.
8571
Georg Brandl871f1bc2007-03-12 13:17:36 +00008572- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008573 its argument, if it exists. If not, it will work like before. This
8574 allows customizing the output of dir() in the presence of a
8575 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008576
Collin Winter276887b2007-03-12 16:11:39 +00008577- Patch #922167: Python no longer segfaults when faced with infinitely

Georg Brandl3ee81df2008-05-17 18:14:43 +00008583- Patch #1491866: change the complex() constructor to allow
8584 parthensized forms. This means complex(repr(x)) now works instead of
8585 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008586
Georg Brandlaa2321b2007-03-07 00:40:28 +00008587- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008588 makes the filenames the warning module prints much more sensible
8589 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008590
Georg Brandl49aafc92007-03-07 00:34:46 +00008591- Variant of patch #697613: don't exit the interpreter on a SystemExit
8592 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008593 variable is given, but break into the interactive interpreter just
8594 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008602- Patch #1674228: when assigning a slice (old-style), check for the
8603 sq_ass_slice instead of the sq_slice slot.
8604
Georg Brandl3ee81df2008-05-17 18:14:43 +00008605- When printing an unraisable error, don't print exceptions. before
8606 the name. This duplicates the behavior whening normally printing
8607 exceptions.

9234 -- the failure just occurred later, with a more cumbersome
9235 exception.

Thomas Hellerd2ea4a22006-10-17 19:30:48 +00009446- ctypes callback functions only support 'fundamental' data types as
9447 result type. Raise an error when something else is used. This is a

9508 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009509
Georg Brandl3ee81df2008-05-17 18:14:43 +00009510- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9511 with RFC 3207 and forgets any knowledge obtained from the server not
9512 obtained from the TLS negotiation itself. Patch contributed by Bill
9513 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009514
Georg Brandl3ee81df2008-05-17 18:14:43 +00009515- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009516 that the SMTP.starttls() caller no longer needs to call ehlo()
9517 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009518 does not claim to support starttls. Adds the
9519 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9520 Fenner.

9558
Georg Brandl3ee81df2008-05-17 18:14:43 +00009559- Patch #1663329: added ``os.closerange()`` function to quickly close

9600 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9601 silently miscode subclasses of those types. Now, it raises a
9602 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009603

Georg Brandl3ee81df2008-05-17 18:14:43 +00009618 time so that opening a database previously created with the DB_DUP
9619 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9620 opens. Specifically: dictionary assignment to a DB object will
9621 replace all values for a given key when the database allows
9622 duplicate values. DB users should use DB.put(k, v) when they want
9623 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009624

9630 characters with ASCII value less than 32. Also, it correctly quotes
9631 dots only if they occur on a single line, as opposed to the previous
9632 behavior of quoting dots if they are the second character of any
9633 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009634

9961-----
9962
Georg Brandl3ee81df2008-05-17 18:14:43 +00009963- Unified naming convention for free lists and their limits. All free
9964 lists in Object/ are named ``free_list``, the counter ``numfree``
9965 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9966 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009967
Georg Brandl3ee81df2008-05-17 18:14:43 +00009968- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9969 to ``PyTuple_SetItem``, it can be used to populate a brand new
9970 frozenset; but it does not steal a reference to the added item.

9979
9980- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9981 ``PyFloat_GetInfo()`` to the float API.
9982
Georg Brandl3ee81df2008-05-17 18:14:43 +00009983- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9984 of w# format code incorrectly truncated the length to an int, even
9985 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9986 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009987
Georg Brandl3ee81df2008-05-17 18:14:43 +00009988- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

10005
10006- Fix some leftovers from the conversion from int to Py_ssize_t
10007 (relevant to strings and sequences of more than 2**31 items).
10008
10009- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10010 outside of pystate.c and should not be necessary.
10011
Georg Brandl3ee81df2008-05-17 18:14:43 +000010012- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10013 absolute imports. In earlier versions they might have used relative
10014 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010015
Georg Brandl3ee81df2008-05-17 18:14:43 +000010016- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10017 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010018
Georg Brandl3ee81df2008-05-17 18:14:43 +000010019- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010025- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10026 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10027 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10028 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010029

Georg Brandl3ee81df2008-05-17 18:14:43 +000010042- Removed the macfs module. It had been deprecated since Python 2.5.
10043 This lead to the deprecation of macostools.touched() as it relied
10044 solely on macfs and was a no-op under OS X.
