11
Victor Stinner66c6e9d2013-12-13 02:37:09 +010012- Issue #14432: Generator now clears the borrowed reference to the thread
13 state. Fix a crash when a generator is created in a C thread that is
14 destroyed while the generator is still used. The issue was that a generator
15 contains a frame, and the frame kept a reference to the Python state of the
16 destroyed C thread. The crash occurs when a trace function is setup.
17
Victor Stinner7821ff32013-12-10 01:23:22 +010018- Issue #19932: Fix typo in import.h, missing whitespaces in function prototypes.

Gregory P. Smith9ffb1482013-12-10 18:22:03 -080029- Issue #17200: telnetlib's read_until and expect timeout was broken by the
30 fix to Issue #14635 in Python 2.7.4 to be interpreted as milliseconds
31 instead of seconds when the platform supports select.poll (ie: everywhere).
32 It is now treated as seconds once again.

46 behaviour when Pickler.persistent_id returns None, but not for any other
Alexandre Vassalotti34ca0662013-11-30 14:02:47 -080047 false values. This allows false values other than None to be used as
48 persistent IDs. This behaviour is consistent with cPickle.
Alexandre Vassalotti1d3a1732013-11-30 13:24:13 -080049
Serhiy Storchaka6d9d30d2013-11-26 22:47:05 +020050- Issue #11508: Fixed uuid.getnode() and uuid.uuid1() on environment with

Nadeem Vawda6cad3712012-11-05 00:55:06 +01001173 successive calls after EOF in unused_data, instead of only saving the argument
Nadeem Vawda252f4dc2012-11-11 02:14:15 +01001174 to the last call. decompressobj().flush() now correctly sets unused_data and

Ned Deily18fae3f2013-01-31 01:24:55 -08001498- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1499 In particular, fix extension module build failures when trying to use
1500 32-bit-only installer Pythons on systems with Xcode 4 (currently
1501 OS X 10.8, 10.7, and optionally 10.6).
1502 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1503 * Since Xcode 4 removes ppc support, extension module builds now
1504 check for ppc compiler support and by default remove ppc and
1505 ppc64 archs when they are not available.
1506 * Extension module builds now revert to using system installed
1507 headers and libs (/usr and /System/Library) if the SDK used
1508 to build the interpreter is not installed or has moved.
1509 * Try to avoid building extension modules with deprecated
1510 and problematic Apple llvm-gcc compiler. If original compiler
1511 is not available, use clang instead by default.

1866 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01001942- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1943 Distutils-based packages with C extension modules may fail because
1944 Apple has removed gcc-4.2, the version used to build python.org
1945 64-bit/32-bit Pythons. If the user does not explicitly override
1946 the default C compiler by setting the CC environment variable,
1947 Distutils will now attempt to compile extension modules with clang
1948 if gcc-4.2 is required but not found. Also as a convenience, if
1949 the user does explicitly set CC, substitute its value as the default
1950 compiler in the Distutils LDSHARED configuration variable for OS X.
1951 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1952 SDK, neither of which are available in Xcode 4. This change does not
1953 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002203- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2204 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2205 interpreter process. This could cause failures in non-Distutils subprocesses
2206 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002207 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002208 deployment target only in the environment of each build subprocess. It is
2209 still possible to globally override the default by setting
2210 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2211 greater or equal to the default value, the value with which the interpreter
2212 was built.

2241 updating the check interval, so if the user decreases the check interval,
2242 the ticker doesn't have to wind down to zero from the old starting point
2243 before the new interval takes effect. And if the user increases the
2244 interval, it makes sure the new limit takes effect right away rather have an
2245 early task switch before recognizing the new interval.

3207
Antoine Pitrou6391b342010-09-14 18:48:19 +00003208- Issue #9854: The default read() implementation in io.RawIOBase now
3209 handles non-blocking readinto() returning None correctly.
3210
Antoine Pitrouf7f390a2010-09-14 14:37:18 +00003211- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
3212 SSLSocket.sendto() to match the corresponding socket methods. Also,
3213 fix various SSLSocket methods to raise socket.error rather than an
3214 unhelpful TypeError when called on an unconnected socket. Original patch
3215 by Andrew Bennetts.
3216

3224
Raymond Hettinger20397532010-09-12 02:11:45 +00003225- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3226 This prevents user-created self-referencing ordered dictionaries from
3227 becoming permanently uncollectable GC garbage. The downside is that
3228 removing __del__ means that the internal doubly-linked list has to wait for
3229 GC collection rather than freeing memory immediately when the refcnt drops
3230 to zero.
3231
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003232- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3235
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003236- Issue #9792: In case of connection failure, socket.create_connection()
3237 would swallow the exception and raise a new one, making it impossible
3238 to fetch the original errno, or to filter timeout errors. Now the
3239 original error is re-raised.
3240
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003241- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3242 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3243 be updated back after the system call. Original patch by Brian Brazil.

3249 ConfigParser.write.
3250
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003251- Issue #808164: Fixed socket.close to avoid references to globals, to
3252 avoid issues when socket.close is called from a __del__ method.
3253

3255 can be set to False to turn off the previously undocumented 'popularity'
3256 heuristic. Patch by Terry Reedy and Eli Bendersky
3257

3259 falling into recursion.
3260
R. David Murray7c4bf552010-08-25 01:45:57 +00003261- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3262 character years even if the message contains RFC822 two character years.
3263
Daniel Stutzbach91287322010-08-24 21:09:30 +00003264- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00003275- Issue #9214: Set operations on KeysView or ItemsView in the collections
3276 module now correctly return a set. (Patch by Eli Bendersky.)
3277
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003278- Issue #9617: Signals received during a low-level write operation aren't
3279 ignored by the buffered IO layer anymore.
3280
Benjamin Peterson52c36052010-08-21 03:03:22 +00003281- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3282 are not held onto after they are deleted elsewhere.
3283
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003284- Issue #9626: the view methods for collections.OrderedDict() were returning
3285 the unordered versions inherited from dict. Those methods are now
3286 overridden to provide ordered views.
3287
Éric Araujo0389ae62010-08-14 03:07:46 +00003288- Issue #8688: MANIFEST files created by distutils now include a magic
3289 comment indicating they are generated. Manually maintained MANIFESTs
3290 without this marker will not be overwritten or removed.
3291
Antoine Pitroue1436d12010-08-12 15:25:51 +00003292- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3293 and a BadZipfile error is raised if it doesn't match (as used to be the
3294 case in Python 2.5 and earlier).
3295
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003296- Issue #9550: a BufferedReader could issue an additional read when the
3297 original read request had been satisfied, which could block indefinitely
3298 when the underlying raw IO channel was e.g. a socket. Report and original
3299 patch by Jason V. Miller.
3300
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003301- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00003319- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
3320 This is how it is supposed to work, wget and curl do the same. Previous
3321 behavior was wrong.

3329 the option character for the added 'h/help' option if prefix_chars
3330 does not contain a '-', instead of raising an error.
3331

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003688- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3689 start byte and the continuation byte(s) are now considered invalid, instead

3691 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3692 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3693 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3704 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

4073
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004074- Issue #7301: Add environment variable $PYTHONWARNINGS.
4075
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004076- Issue #8329: Don't return the same lists from select.select when no fds are
4077 changed.
4078
Georg Brandlfee0f442010-05-22 21:26:21 +00004079- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004080 on 64-bit machines. The shift count for either left or right shift is
4081 permitted to be up to sys.maxsize.

4088
Georg Brandlfee0f442010-05-22 21:26:21 +00004089- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4090 with a non-empty format string. This is an effort to future-proof user
4091 code. If a derived class does not currently implement __format__ but later
4092 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004093 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004094 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004095

4126
Georg Brandlfee0f442010-05-22 21:26:21 +00004127- Issue #8257: The Decimal construct now accepts a float instance directly,
4128 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004129
4130 >>> Decimal(1.1)
4131 Decimal('1.100000000000000088817841970012523233890533447265625')
4132
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004133- collections.Counter() now supports a subtract() method.
4134
Georg Brandlfee0f442010-05-22 21:26:21 +00004135- The functools module now has a total_ordering() class decorator to simplify
4136 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004138- The functools module also adds cmp_to_key() as a tool to transition old-style
4139 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004140
Georg Brandlfee0f442010-05-22 21:26:21 +00004141- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4142 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004143
Georg Brandlfee0f442010-05-22 21:26:21 +00004144- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4145 InvalidOperation instead of returning False. (Comparisons involving a quiet
4146 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4147 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004148
Georg Brandlfee0f442010-05-22 21:26:21 +00004149- Issue #2531: Comparison operations between floats and Decimal instances now
4150 return a result based on the numeric values of the operands; previously they
4151 returned an arbitrary result based on the relative ordering of id(float) and
4152 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004153
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004154- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004155 argument `-` which tells it to read files to compile from stdin. Each line is
4156 read on demand and the named file is compiled immediately. (Original patch by
4157 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00004162- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4163 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004164 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004165
Georg Brandlfee0f442010-05-22 21:26:21 +00004166- Comparisons using one of <, <=, >, >= between a complex instance and a
4167 Fractions instance now raise TypeError instead of returning True/False. This
4168 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4169 <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004268- Issue #8300: When passing a non-integer argument to struct.pack with any
4269 integer format code, struct.pack first attempts to convert the non-integer
4270 using its __index__ method. If that method is non-existent or raises
4271 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00004273- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4274 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4275 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004276 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4277 inconsistent: __int__ was used for some integer codes but not for others, and
4278 the set of integer codes for which it was used differed between native packing
4279 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004491- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4492 now also used by regrtest to run all the tests in a temporary directory. The
4493 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4494 Xicluna who helped with the patch.

4511 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004512 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00004531- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4532 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4533 returning NULL. The macro now returns a statically allocated empty string
4534 instead.

4544 strings,
4545 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4546 numeric strings corresponding to subnormal values,
4547 (3) a memory leak for some values large enough to cause overflow, and
4548 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00004580 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004586- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004587 file position when calling `truncate()`. It would previously change the file
4588 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004589 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4590
Georg Brandlba83f822010-03-14 09:50:54 +00004591- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4592 class used to represent files stored inside an archive. The new
4593 implementation is significantly faster and can be wrapped in a
4594 ``io.BufferedReader`` object for more speedups. It also solves an issue
4595 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4596 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004606- Issue #7748: Since unicode values are supported for some metadata options in
4607 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4608 encoded string for them. This ensures that the upload and register commands
4609 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004686- The ``__complex__()`` method is now looked up on the class of instances to
4687 make it consistent with other special methods.

4691
Mark Dickinson1b34d252010-01-01 17:27:30 +00004692- Issue #5080: A number of functions and methods previously produced a

4694 These functions and methods now raise TypeError instead. The majority of the
4695 effects of this change are in the extension modules, but some core functions
4696 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4697 and many unicode/str methods.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004878
Georg Brandlba83f822010-03-14 09:50:54 +00004879- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4880 decimal string that's guaranteed to round back to x under correct rounding
4881 (with round-half-to-even rounding mode). Previously it gave a string based on
4882 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4883 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4884 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004885
Georg Brandlba83f822010-03-14 09:50:54 +00004886- Issue #7117: On almost all platforms: float-to-string and string-to-float
4887 conversions within Python are now correctly rounded. Places these conversions
4888 occur include: str for floats and complex numbers; the float and complex
4889 constructors; old-style and new-style numeric formatting; serialization and
4890 deserialization of floats and complex numbers using marshal, pickle and json;
4891 parsing of float and imaginary literals in Python code; Decimal-to-float
4892 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004893
Georg Brandlba83f822010-03-14 09:50:54 +00004894 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4895 providing correctly-rounded strtod and dtoa C functions. This code is
4896 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4897 the C compiler. There may be a small number of platforms on which correct
4898 operation of this code cannot be guaranteed, so the code is not used: notably,
4899 this applies to platforms where the C double format is not IEEE 754 binary64,
4900 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4901 and Python's configure script is unable to determine how to change the FPU
4902 precision. On these platforms conversions use the platform strtod and dtoa,
4903 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004904
Georg Brandlba83f822010-03-14 09:50:54 +00004905- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4906 uses the correctly-rounded string <-> float conversions described above (when
4907 available), and so produces correctly rounded results that will display nicely
4908 under the float repr. There are two related small changes: (1) round now
4909 accepts any class with an ``__index__()`` method for its second argument (but
4910 no longer accepts floats for the second argument), and (2) an excessively
4911 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4912 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005059- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5060 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5061 but with at least one decimal point and with a default precision
5062 of 12. Previously, the behavior the same but with a default precision of 6.
5063 This more closely matches ``str()``, and reduces surprises when adding
5064 alignment flags to the empty presentation type. This also affects the new
5065 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00005205- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5206 existing .py counterpart, override the co_filename attributes of all code

5262
Georg Brandlba83f822010-03-14 09:50:54 +00005263- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5264 file objects with closefd=False. The file descriptor is still kept open but
5265 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00005289- On windows, ``os.chdir()`` given unicode was not working if

5291 this code path is really executed because I cannot move to such directory on
5292 win2k)

5295 element is temporarily replaced with an equivalent frozenset. But the
5296 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00005317- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5318 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5319 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5320 of using the replace error handler in PyUnicode_DecodeUTF8().
5321
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005322- Issue #3739: The unicode-internal encoder now reports the number of characters

5324
Georg Brandlba83f822010-03-14 09:50:54 +00005325- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5327 gives improved memory leak detection when running under Valgrind, while taking
5328 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00006575 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6576 the tests if DISPLAY is defined but can't be used.

6697
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006698- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6699 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6700 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6701 ``printf`` function, whereas PyString_FromFormat has an independent
6702 implementation and uses "%zd" on all platforms for size_t values.
6703 This makes a difference on win64, where ``printf`` needs "%Id" to display
6704 64bit values.

6710 object; previously an int would be returned for small values. the __long__
6711 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006721 was correctly parsed but parsing of subsequent arguments failed.
6722
Vinay Sajip35e3b032008-09-01 14:33:59 +00006723- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006724 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6725 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6726 when given a tuple of classes as second argument, were looking up
6727 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6728 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006867What's New in Python 2.6 beta 3?
6868================================
6869
Barry Warsaw07a4a382008-08-21 01:15:08 +00006870*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006871
6872Core and Builtins
6873-----------------
6874
Guido van Rossumf8402962008-08-20 15:01:50 +00006875- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6876 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6877 extensions do not automatically benefit from the class attribute
6878 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6879 to their tp_flags field if they care. This is a backwards
6880 compatibility feature; in 3.0, all types will use the cache by
6881 default.
6882
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006883- Keyword arguments can now follow starred arguments. (``f(a, *args,
6884 keyword=23)`` is now valid syntax.)
6885
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006886- ctypes function pointers that are COM methods have a boolean True
6887 value again.
6888
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006889- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6890 by denying s# to parse objects that have a releasebuffer procedure,
6891 and introducing s*.
6892
Georg Brandl1e13ea92008-08-11 09:07:59 +00006893- Issue #3537: Fix an assertion failure when an empty but presized dict
6894 object was stored in the freelist.
6895
Mark Dickinsonb6467572008-08-04 21:30:09 +00006896- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6897 ValueError consistently across platforms.
6898
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006899- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6900 (64bit Unix, for example), unichr() would truncate its argument and return
6901 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6902
Neal Norwitze7d8be82008-07-31 17:17:14 +00006903- Apply security patches from Apple.
6904
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006905- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6906 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6907
Antoine Pitrou92f82162008-07-25 22:22:08 +00006908- Issue #1819: function calls with several named parameters are now on
6909 average 35% faster (as measured by pybench).
6910
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006911- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6912 the python debugger steps into a class statement: the free variables (local
6913 variables defined in an outer scope) would be deleted from the outer scope.
6914
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006915- Issue #2620: Overflow checking when allocating or reallocating memory
6916 was not always being done properly in some python types and extension
6917 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6918 all been updated to perform better checks and places in the code that
6919 would previously leak memory on the error path when such an allocation
6920 failed have been fixed.
6921
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006922Library
6923-------
6924
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006925- Issue #3612: Added some missing basic types in ctypes.wintypes.
6926
Benjamin Petersone977ad42008-08-20 01:42:01 +00006927- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6928 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6929
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006930- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6931 version reported by these tools does not necessarily follow the python
6932 version numbering scheme, so the module is less strict when parsing it.
6933
Nick Coghlanf70385a2008-08-18 12:42:46 +00006934- Issue #2235: Added Py3k warnings for types which will become unhashable
6935 under the stricter __hash__ inheritance rules in 3.0. Several types
6936 which did not meet the rules for hash invariants and were already
6937 unhashable in 3.0 have now been explicitly flagged as unhashable in
6938 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6939 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6940
Brett Cannon88f801d2008-08-18 00:46:22 +00006941- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6942 imported into the module but exposed as part of the module's API.
6943
Brett Cannon7b96f072008-08-18 00:41:11 +00006944- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6945
Brett Cannon46225e72008-08-18 00:36:52 +00006946- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6947
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006948- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6949
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006950- Issue #3575: Incremental decoder's decode function now takes bytearray
6951 by using 's*' instead of 't#'.
6952
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006953- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006954 fails unicode conversion on 2nd parameter. (windows only)
6955
Georg Brandl222e2082010-08-01 22:27:39 +00006956- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006957 in a redirect.
6958
Brett Cannonabe423e2008-08-16 21:47:07 +00006959- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006960 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006961
Facundo Batistaeb90b782008-08-16 14:44:07 +00006962- Issue #2776: fixed small issue when handling an URL with double slash
6963 after a 302 response in the case of not going through a proxy.
6964
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006965- Issue #2676: in the email package, content-type parsing was hanging on
6966 pathological input because of quadratic or exponential behaviour of a
6967 regular expression.
6968
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006969- Issue #3476: binary buffered reading through the new "io" library is now
6970 thread-safe.
6971
Brett Cannonbf3157b2008-08-14 05:00:03 +00006972- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6973 since mimetools itself is deprecated. Because modules are cached, all
6974 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6975
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006976- Issue #3134: shutil referenced undefined WindowsError symbol.
6977
Robert Schuppenies14646332008-08-10 11:01:53 +00006978- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6979 menu entries were not deleted.
6980
Brett Cannon83e81842008-08-09 23:30:55 +00006981- Copied the implementation of reduce() to _functools.reduce() to have a
6982 version that did not raise a DeprecationWarning under -3.
6983
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006984- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6985 a MemoryError rather than silently stop the iteration.
6986
Guido van Rossum59ce9012008-08-09 14:55:34 +00006987- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6988 to _sre.compile() will now be rejected. This should not affect anybody
6989 since the re.compile() function never generates invalid re-bytecode.
6990
Skip Montanaroa032bf42008-08-08 22:52:51 +00006991- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6992 upon first access it can be automatically initialized from the csv file if
6993 it wasn't initialized during instantiation.
6994
Brett Cannon3aa2a492008-08-06 22:28:09 +00006995- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6996 the reload() built-in has been removed.
6997
Brett Cannon7e30b672008-08-04 21:52:25 +00006998- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006999 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7002 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
7003 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
7004 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007005
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007006- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7007 raised an AttributeError.
7008
Benjamin Peterson01a24322008-07-28 23:35:27 +00007009- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007010 asking for a specific length. This problem only affected files opened
7011 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007012
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007013- Issue #3449: Update decimal module to use most recent specification
7014 (v. 1.68) and tests (v. 2.58) from IBM.
7015
Georg Brandl222e2082010-08-01 22:27:39 +00007016- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007017

7020
Georg Brandlf9efabb2008-07-23 15:16:45 +00007021- Deprecate the "ast" parser function aliases.
7022
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007023- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7024
7025- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7026 invalid arguments.
7027
7028- Issue #3302: Fix several crashes when calling locale's gettext functions
7029 with None arguments.
7030
7031- Issue #3389: Allow resolving dotted names for handlers in logging
7032 configuration files.
7033
7034- Deprecate the sunaudio module for removal in Python 3.0.
7035
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007036- Issue #3394: zipfile.writestr sets external attributes when passed a
7037 file name rather than a ZipInfo instance, so files are extracted with
7038 mode 0600 rather than 000 under Unix.
7039
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007040- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7041 argument in python 2.5, this broke code that subclassed Popen to include its
7042 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7051
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007052- Issue #2235: the C API function PyObject_HashNotImplemented and its
7053 interaction with the tp_hash slot (added in 2.6b2) are now documented
7054
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007055- Issue #643841: The language reference now provides more detailed
7056 coverage of the lookup process for special methods. The disclaimers
7057 regarding lack of coverage of new-style classes have also been
7058 removed, since the coverage is now fairly reasonable.

7062================================
7063
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007064*Release date: 17-Jul-2008*
7065
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007066Core and Builtins
7067-----------------
7068
Georg Brandl3e483f62008-07-16 22:57:41 +00007069- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7070 its methods now allow for items objects that can be converted to
7071 an integer using operator.index().
7072
Mark Dickinson64b7e502008-07-16 09:40:03 +00007073- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7074 produced a ValueError instead of giving the correct float.
7075
Eric Smitha5fa5a22008-07-16 00:11:49 +00007076- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7077 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7078
Mark Dickinson7103aa42008-07-15 19:08:33 +00007079- Issue #3008: the float type has a new instance method 'float.hex'
7080 and a new class method 'float.fromhex' to convert floating-point
7081 numbers to and from hexadecimal strings, respectively.
7082
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007083- Issue #2235: __hash__ is once again inherited by default. To allow
7084 collections.Hashable to remain meaningful in the presence of the
7085 default hash implementation (object.__hash__), it is now possible
7086 to explicit block inheritance of hash by setting __hash__=None at
7087 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7088 level.
7089
Nick Coghlanb028f502008-07-13 14:52:36 +00007090- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7091 the parent module cannot be found while performing an absolute import.
7092 This means that an incorrectly defined __package__ attribute will
7093 now only prevent relative imports in that module rather than causing
7094 all imports from that module to fail.
7095
Nick Coghlan14ff9942008-07-08 14:21:42 +00007096- Issue #2517: Allow unicode messages in Exceptions again by correctly
7097 bypassing the instance dictionary when looking up __unicode__ on
7098 new-style classes.
7099
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007100- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7101 set to a custom object whose write() method happens to install
7102 another file in sys.stdout.

7106 another thread's dictionary.
7107
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007108- Issue #3004: Minor change to slice.indices(): the start and stop
7109 arguments are now treated identically, making the behaviour easier
7110 to describe and understand. For example, slice(None, -10,
7111 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7112 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7113 10, -1).
7114
Georg Brandl278fc502008-07-19 12:46:12 +00007115- Issue #3219: Calling a function with repeated keyword arguments,
7116 f(a=2, a=23), would not cause a syntax error. This was a regression
7117 from 2.4 caused by the switch to the new compiler.

7564 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007565 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007566
7567 This is controlled by the configure argument ``--with-universal-archs``:
7568
7569 - ``--with-universal-archs=all``: install 4-way universal
7570
7571 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7572
7573 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7574
7575 This option should be used in combination with ``--enable-universalsdk=``.
7576
7577 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 +00007626- Issue #1631171: Re-implement the 'warnings' module in C (the
7627 original Python code has been kept as backup). This will allow for
7628 using the 'warning's machinery in such places as the parser where
7629 use of pure Python code is not possible. Both the ``showarning()``
7630 and ``formatwarning()`` gain an optional 'line' argument which is
7631 not called by default for backwards-compatibility reasons. Setting
7632 ``warnings.showwarning()`` to an implementation that lacks support
7633 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007658- The getpass module has been improved on Unix. It now uses /dev/tty
7659 by default and uses stderr instead of stdout. A GetPassWarning is
7660 issued when input echo cannot be controlled.

7687
Georg Brandl3ee81df2008-05-17 18:14:43 +00007688- Issue #2385: distutils.core.run_script() makes __file__ available,
7689 so the controlled environment will more closely mirror the typical
7690 script environment. This supports setup.py scripts that refer to
7691 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007696- Issue #2550: The approach used by client/server code for obtaining
7697 ports to listen on in network-oriented tests has been refined in an
7698 effort to facilitate running multiple instances of the entire
7699 regression test suite in parallel without issue.
7700 test_support.bind_port() has been fixed such that it will always
7701 return a unique port -- which wasn't always the case with the
7702 previous implementation, especially if socket options had been set
7703 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7704 new implementation of bind_port() will actually raise an exception
7705 if it is passed an AF_INET/SOCK_STREAM socket with either the
7706 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7707 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7708 the socket it's been passed. This currently only applies to
7709 Windows. This option prevents any other sockets from binding to the
7710 host/port we've bound to, thus removing the possibility of the
7711 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7712 when a second SOCK_STREAM socket binds and accepts to a host/port
7713 that's already been bound by another socket. The optional preferred
7714 port parameter to bind_port() has been removed. Under no
7715 circumstances should tests be hard coding ports!
7716
7717 test_support.find_unused_port() has also been introduced, which will
7718 pass a temporary socket object to bind_port() in order to obtain an
7719 unused port. The temporary socket object is then closed and
7720 deleted, and the port is returned. This method should only be used
7721 for obtaining an unused port in order to pass to an external program
7722 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7723 a parameter to a server-oriented class that doesn't give you direct
7724 access to the underlying socket used.
7725
7726 Finally, test_support.HOST has been introduced, which should be used
7727 for the host argument of any relevant socket calls (i.e. bind and
7728 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007729
7730 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007731 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007732 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7733 test_asynchat and test_socket_ssl.
7734
Georg Brandl3ee81df2008-05-17 18:14:43 +00007735 It is now possible for multiple instances of the regression test
7736 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008015- Added the future_builtins module, which contains hex() and oct().
8016 These are the PEP 3127 version of these functions, designed to be
8017 compatible with the hex() and oct() builtins from Python 3.0. They
8018 differ slightly in their output formats from the existing, unchanged
8019 Python 2.6 builtins. The expected usage of the future_builtins
8020 module is:
8021 from future_builtins import hex, oct
8022
Eric Smith7ef40bf2008-02-20 23:34:22 +00008023- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8024 exponents for exponents with absolute value < 100. Follows C99
8025 standard. This is a change on Windows, which would use 3 digits.
8026 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8027 so that any alterations it does to the resulting string will be
8028 available in stringlib/formatter.h (for float.__format__).
8029
Eric Smith5a3c1352008-02-19 13:21:56 +00008030- Implemented PEP 3101, Advanced String Formatting. This adds a new
8031 builtin format(); a format() method for str and unicode; a
8032 __format__() method to object, str, unicode, int, long, float, and
8033 datetime; the class string.Formatter; and the C API
8034 PyObject_Format().
8035
Georg Brandl3ee81df2008-05-17 18:14:43 +00008036- Fixed several potential crashes, all caused by specially crafted
8037 __del__ methods exploiting objects in temporarily inconsistent
8038 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008039
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008040- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008041 prevent a possible crash: an Abstract Base Class would try to access
8042 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008043

Georg Brandl3ee81df2008-05-17 18:14:43 +00008047- Clear all free lists during a gc.collect() of the highest generation
8048 in order to allow pymalloc to free more arenas. Python may give back
8049 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008050
Georg Brandl3ee81df2008-05-17 18:14:43 +00008051- Issue #2045: Fix an infinite recursion triggered when printing a
8052 subclass of collections.defaultdict, if its default_factory is set
8053 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008054
Christian Heimesf75dbef2008-02-08 00:11:31 +00008055- Fixed a minor memory leak in dictobject.c. The content of the free
8056 list was not freed on interpreter shutdown.
8057
Georg Brandl21e99f42010-03-07 15:23:59 +00008058- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008059 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008060
Georg Brandl3ee81df2008-05-17 18:14:43 +00008061- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8062 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008063 to compact the internal free lists of pre-allocted ints and floats.
8064
Georg Brandl3ee81df2008-05-17 18:14:43 +00008065- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8066 calls. Python expected the return type int but the fork familie
8067 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008068
Georg Brandl3ee81df2008-05-17 18:14:43 +00008069- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008081- Patch #1473257: generator objects gain a gi_code attribute. This is
8082 the same object as the func_code attribute of the function that
8083 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008084
Georg Brandl3ee81df2008-05-17 18:14:43 +00008085- Issue #1920: "while 0" statements were completely removed by the
8086 compiler, even in the presence of an "else" clause, which is
8087 supposed to be run when the condition is false. Now the compiler
8088 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008089
Guido van Rossumeead05f2008-01-24 18:21:02 +00008090- A few crashers fixed: weakref_in_del.py (issue #1377858);
8091 loosing_dict_ref.py (issue #1303614, test67.py);
8092 borrowed_ref_[34].py (not in tracker).
8093
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008094- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008095 suppressed while an extension is loaded by calling SetErrorMode in
8096 dynload_win.c. The error is still reported properly.
8097
Georg Brandl3ee81df2008-05-17 18:14:43 +00008098- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008099 several extension methods and modules do not work without unicode
8100 support.
8101
Georg Brandl26543b12008-01-21 18:36:51 +00008102- Issue #1882: when compiling code from a string, encoding cookies in the
8103 second line of code were not always recognized correctly.
8104
Georg Brandl14404b62008-01-19 19:27:05 +00008105- Issue #1679: "0x" was taken as a valid integer literal.
8106
Georg Brandl6caad7d2008-01-26 14:19:22 +00008107- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008108 added.
8109
Christian Heimesc94e2b52008-01-14 04:13:37 +00008110- sys.float_info / PyFloat_GetInfo: The floating point information
8111 object was converted from a dict to a specialized structseq object.
8112
Georg Brandl3ee81df2008-05-17 18:14:43 +00008113- Patch #1816: Added sys.flags structseq. It exposes the status of
8114 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008115
Georg Brandl3ee81df2008-05-17 18:14:43 +00008116- Objects/structseq.c: Implemented new structseq representation. The
8117 patch makes structseqs (e.g. the return value of os.stat) more
8118 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008119
Georg Brandl3ee81df2008-05-17 18:14:43 +00008120- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00008142 and INF. float("nan"), float("inf") and float("-inf") now work on
8143 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008144
Georg Brandl3ee81df2008-05-17 18:14:43 +00008145- Compiler now generates simpler and faster code for dictionary
8146 literals. The oparg for BUILD_MAP now indicates an estimated
8147 dictionary size. There is a new opcode, STORE_MAP, for adding
8148 entries to the dictionary.

Neal Norwitz44f326e2007-10-05 05:29:17 +00008190- Fix warnings found by the new version of the Coverity checker.
8191
Georg Brandl21e99f42010-03-07 15:23:59 +00008192- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008193 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8194 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008195
Georg Brandl3ee81df2008-05-17 18:14:43 +00008196- Issue #1686386: Tuple's tp_repr did not take into account the
8197 possibility of having a self-referential tuple, which is possible
8198 from C code. Nor did object's tp_str consider that a type's tp_str
8199 could do something that could lead to an inifinite recursion.
8200 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8201 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008202
Georg Brandl3ee81df2008-05-17 18:14:43 +00008203- Issue #1164: It was possible to trigger deadlock when using the
8204 'print' statement to write to a file since the GIL was not released
8205 as needed. Now PyObject_Print() does the right thing along with
8206 various tp_print implementations of the built-in types and those in
8207 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008208
Georg Brandl3ee81df2008-05-17 18:14:43 +00008209- Issue #1147: Exceptions were directly allowing string exceptions in
8210 their throw() method even though string exceptions no longer
8211 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008212
Georg Brandl3ee81df2008-05-17 18:14:43 +00008213- Issue #1096: Prevent a segfault from getting the repr of a very
8214 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008215
Brett Cannon1e534b52007-09-07 04:18:30 +00008216- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008217 PyObject_Call() never calling back out to Python code to trigger
8218 recursion depth updates/checks. Required the creation of a static
8219 RuntimeError instance in case normalizing an exception put the
8220 recursion check value past its limit. Fixes crashers
8221 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008222
Georg Brandl3ee81df2008-05-17 18:14:43 +00008223- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008236- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008237 __*__ attributes. (Some already existed, e.g., __doc__ and
8238 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008239
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008240- Add -3 option to the interpreter to warn about features that are
8241 deprecated and will be changed/removed in Python 3.0.
8242
Georg Brandl2134e752007-05-21 20:34:16 +00008243- Patch #1686487: you can now pass any mapping after '**' in function
8244 calls.
8245
Collin Winter62903052007-05-18 23:11:24 +00008246- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008247 "except E as target:". This is to provide forwards compatibility
8248 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008249
Brett Cannon229cee22007-05-05 01:34:02 +00008250- Deprecate BaseException.message as per PEP 352.
8251
Georg Brandl3ee81df2008-05-17 18:14:43 +00008252- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008253 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008254
Vinay Sajip8549ce32007-05-06 17:53:37 +00008255- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008256 setting a plain string, ie don't expand to single letter identifiers.
8257
Raymond Hettinger13936692007-04-11 18:40:58 +00008258- Request #1191699: Slices can now be pickled.
8259
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008260- Request #1193128: str.translate() now allows a None argument for
8261 translations that only remove characters without re-mapping the
8262 remaining characters.
8263
Georg Brandl5cb76c12007-03-21 09:00:39 +00008264- Patch #1682205: a TypeError while unpacking an iterable is no longer
8265 masked by a generic one with the message "unpack non-sequence".
8266
Neal Norwitzaa754b72007-03-21 06:39:48 +00008267- Remove unused file Python/fmod.c.
8268
Guido van Rossum143b5642007-03-23 04:58:42 +00008269- Bug #1683368: The object.__init__() and object.__new__() methods are
8270 now stricter in rejecting excess arguments. The only time when
8271 either allows excess arguments is when it is not overridden and the
8272 other one is. For backwards compatibility, when both are
8273 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008274 warning later). Also, type.__init__() insists on the same signature
8275 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008276
Georg Brandl3ee81df2008-05-17 18:14:43 +00008277- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8278 object to complex using its __complex__() method before falling back
8279 to the __float__() method. Therefore, the functions in the cmath
8280 module now can operate on objects that define a __complex__()
8281 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008282
Georg Brandl3ee81df2008-05-17 18:14:43 +00008283- Patch #1623563: allow __class__ assignment for classes with
8284 __slots__. The old and the new class are still required to have the
8285 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008286

Georg Brandl3ee81df2008-05-17 18:14:43 +00008290- Patch #1462488: Python no longer segfaults when
8291 ``object.__reduce_ex__()`` is called with an object that is faking
8292 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008293
Georg Brandl3ee81df2008-05-17 18:14:43 +00008294- Patch #1680015: Don't modify __slots__ tuple if it contains an

8298
Georg Brandl7b9c5552007-03-12 14:30:05 +00008299- Bug #1678647: write a newline after printing an exception in any
8300 case, even when converting the value to a string failed.
8301
Georg Brandl871f1bc2007-03-12 13:17:36 +00008302- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008303 its argument, if it exists. If not, it will work like before. This
8304 allows customizing the output of dir() in the presence of a
8305 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008306
Collin Winter276887b2007-03-12 16:11:39 +00008307- Patch #922167: Python no longer segfaults when faced with infinitely
8308 self-recursive reload() calls (as reported by bug #742342).
8309

Georg Brandl3ee81df2008-05-17 18:14:43 +00008313- Patch #1491866: change the complex() constructor to allow
8314 parthensized forms. This means complex(repr(x)) now works instead of
8315 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008316
Georg Brandlaa2321b2007-03-07 00:40:28 +00008317- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008318 makes the filenames the warning module prints much more sensible
8319 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008320
Georg Brandl49aafc92007-03-07 00:34:46 +00008321- Variant of patch #697613: don't exit the interpreter on a SystemExit
8322 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008323 variable is given, but break into the interactive interpreter just
8324 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00008331
Georg Brandl0fca97a2007-03-05 22:28:08 +00008332- Patch #1674228: when assigning a slice (old-style), check for the
8333 sq_ass_slice instead of the sq_slice slot.
8334
Georg Brandl3ee81df2008-05-17 18:14:43 +00008335- When printing an unraisable error, don't print exceptions. before
8336 the name. This duplicates the behavior whening normally printing
8337 exceptions.

8346 created a weakref on itself during a __del__ call for new-style
8347 classes (classic classes still have the bug).

8394
Armin Rigo7ccbca92006-10-04 12:17:45 +00008395- A number of places, including integer negation and absolute value,

8965 exception.

Thomas Hellerd2ea4a22006-10-17 19:30:48 +00009176- ctypes callback functions only support 'fundamental' data types as
9177 result type. Raise an error when something else is used. This is a
9178 partial fix for Bug #1574584.
9179

9238 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009239
Georg Brandl3ee81df2008-05-17 18:14:43 +00009240- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9241 with RFC 3207 and forgets any knowledge obtained from the server not
9242 obtained from the TLS negotiation itself. Patch contributed by Bill
9243 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009244
Georg Brandl3ee81df2008-05-17 18:14:43 +00009245- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009246 that the SMTP.starttls() caller no longer needs to call ehlo()
9247 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009248 does not claim to support starttls. Adds the
9249 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9250 Fenner.

9288
Georg Brandl3ee81df2008-05-17 18:14:43 +00009289- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00009292- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009293 works as expected. ``mmap.find`` also takes an optional ``end``

9330 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9331 silently miscode subclasses of those types. Now, it raises a
9332 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009333

Georg Brandl3ee81df2008-05-17 18:14:43 +00009348 time so that opening a database previously created with the DB_DUP
9349 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9350 opens. Specifically: dictionary assignment to a DB object will
9351 replace all values for a given key when the database allows
9352 duplicate values. DB users should use DB.put(k, v) when they want
9353 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009354

9360 characters with ASCII value less than 32. Also, it correctly quotes
9361 dots only if they occur on a single line, as opposed to the previous
9362 behavior of quoting dots if they are the second character of any
9363 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009364

9691-----
9692
Georg Brandl3ee81df2008-05-17 18:14:43 +00009693- Unified naming convention for free lists and their limits. All free
9694 lists in Object/ are named ``free_list``, the counter ``numfree``
9695 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9696 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009697
Georg Brandl3ee81df2008-05-17 18:14:43 +00009698- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9699 to ``PyTuple_SetItem``, it can be used to populate a brand new
9700 frozenset; but it does not steal a reference to the added item.

9709
9710- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9711 ``PyFloat_GetInfo()`` to the float API.
9712
Georg Brandl3ee81df2008-05-17 18:14:43 +00009713- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9714 of w# format code incorrectly truncated the length to an int, even
9715 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9716 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009717
Georg Brandl3ee81df2008-05-17 18:14:43 +00009718- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9736- Fix some leftovers from the conversion from int to Py_ssize_t
9737 (relevant to strings and sequences of more than 2**31 items).
9738
9739- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9740 outside of pystate.c and should not be necessary.
9741
Georg Brandl3ee81df2008-05-17 18:14:43 +00009742- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9743 absolute imports. In earlier versions they might have used relative
9744 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009745
Georg Brandl3ee81df2008-05-17 18:14:43 +00009746- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9747 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009748
Georg Brandl3ee81df2008-05-17 18:14:43 +00009749- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009755- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9756 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9757 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9758 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009759

Georg Brandl3ee81df2008-05-17 18:14:43 +00009772- Removed the macfs module. It had been deprecated since Python 2.5.
9773 This lead to the deprecation of macostools.touched() as it relied
9774 solely on macfs and was a no-op under OS X.
