13 by inspecting the return value of fwrite(). Based on patches by Jaakko Moisio
14 and Victor Stinner.
15
Victor Stinner66c6e9d2013-12-13 02:37:09 +010016- Issue #14432: Generator now clears the borrowed reference to the thread
17 state. Fix a crash when a generator is created in a C thread that is
18 destroyed while the generator is still used. The issue was that a generator
19 contains a frame, and the frame kept a reference to the Python state of the
20 destroyed C thread. The crash occurs when a trace function is setup.
21
Victor Stinner7821ff32013-12-10 01:23:22 +010022- Issue #19932: Fix typo in import.h, missing whitespaces in function prototypes.

38 fallbacks.

Gregory P. Smith9ffb1482013-12-10 18:22:03 -080051- Issue #17200: telnetlib's read_until and expect timeout was broken by the
52 fix to Issue #14635 in Python 2.7.4 to be interpreted as milliseconds
53 instead of seconds when the platform supports select.poll (ie: everywhere).
54 It is now treated as seconds once again.
55
Serhiy Storchaka5493d5e2013-12-08 17:44:50 +020056- Issue #19099: The struct module now supports Unicode format strings.

68 behaviour when Pickler.persistent_id returns None, but not for any other
Alexandre Vassalotti34ca0662013-11-30 14:02:47 -080069 false values. This allows false values other than None to be used as
70 persistent IDs. This behaviour is consistent with cPickle.
Alexandre Vassalotti1d3a1732013-11-30 13:24:13 -080071

Ned Deily18fae3f2013-01-31 01:24:55 -08001520- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1521 In particular, fix extension module build failures when trying to use
1522 32-bit-only installer Pythons on systems with Xcode 4 (currently
1523 OS X 10.8, 10.7, and optionally 10.6).
1524 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1525 * Since Xcode 4 removes ppc support, extension module builds now
1526 check for ppc compiler support and by default remove ppc and
1527 ppc64 archs when they are not available.
1528 * Extension module builds now revert to using system installed
1529 headers and libs (/usr and /System/Library) if the SDK used
1530 to build the interpreter is not installed or has moved.
1531 * Try to avoid building extension modules with deprecated
1532 and problematic Apple llvm-gcc compiler. If original compiler
1533 is not available, use clang instead by default.

Ned Deily0d0ea482012-02-10 12:59:06 +01001964- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1965 Distutils-based packages with C extension modules may fail because
1966 Apple has removed gcc-4.2, the version used to build python.org
1967 64-bit/32-bit Pythons. If the user does not explicitly override
1968 the default C compiler by setting the CC environment variable,
1969 Distutils will now attempt to compile extension modules with clang
1970 if gcc-4.2 is required but not found. Also as a convenience, if
1971 the user does explicitly set CC, substitute its value as the default
1972 compiler in the Distutils LDSHARED configuration variable for OS X.
1973 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1974 SDK, neither of which are available in Xcode 4. This change does not
1975 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002225- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2226 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2227 interpreter process. This could cause failures in non-Distutils subprocesses
2228 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002229 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002230 deployment target only in the environment of each build subprocess. It is
2231 still possible to globally override the default by setting
2232 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2233 greater or equal to the default value, the value with which the interpreter
2234 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04002262- sys.setcheckinterval() now updates the current ticker count as well as
2263 updating the check interval, so if the user decreases the check interval,
2264 the ticker doesn't have to wind down to zero from the old starting point
2265 before the new interval takes effect. And if the user increases the
2266 interval, it makes sure the new limit takes effect right away rather have an
2267 early task switch before recognizing the new interval.

3213
R. David Murray20ad3632010-10-01 15:48:49 +00003214- Issue #10004: quoprimime no longer generates a traceback when confronted
3215 with invalid characters after '=' in a Q-encoded word.
3216
Antoine Pitrou66b5df62010-09-27 18:16:46 +00003217- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
3218 received. Now sendall() properly calls signal handlers if necessary,
3219 and retries sending if these returned successfully, including on sockets
3220 with a timeout.

3229
Antoine Pitrou6391b342010-09-14 18:48:19 +00003230- Issue #9854: The default read() implementation in io.RawIOBase now
3231 handles non-blocking readinto() returning None correctly.
3232
Antoine Pitrouf7f390a2010-09-14 14:37:18 +00003233- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
3234 SSLSocket.sendto() to match the corresponding socket methods. Also,
3235 fix various SSLSocket methods to raise socket.error rather than an
3236 unhelpful TypeError when called on an unconnected socket. Original patch
3237 by Andrew Bennetts.
3238
Raymond Hettinger74f869e2010-09-13 22:14:36 +00003239- Issue #9826: OrderedDict.__repr__ can now handle self-referential
3240 values: d['x'] = d.

3246
Raymond Hettinger20397532010-09-12 02:11:45 +00003247- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3248 This prevents user-created self-referencing ordered dictionaries from
3249 becoming permanently uncollectable GC garbage. The downside is that
3250 removing __del__ means that the internal doubly-linked list has to wait for
3251 GC collection rather than freeing memory immediately when the refcnt drops
3252 to zero.
3253
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003254- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00003255 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003256 value.
3257
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003258- Issue #9792: In case of connection failure, socket.create_connection()
3259 would swallow the exception and raise a new one, making it impossible
3260 to fetch the original errno, or to filter timeout errors. Now the
3261 original error is re-raised.
3262
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003263- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3264 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3265 be updated back after the system call. Original patch by Brian Brazil.
3266
Antoine Pitroudca9de92010-09-04 17:52:26 +00003267- Issue #1100562: Fix deep-copying of objects derived from the list and

3271 ConfigParser.write.
3272
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003273- Issue #808164: Fixed socket.close to avoid references to globals, to
3274 avoid issues when socket.close is called from a __del__ method.
3275
Terry Reedyd2d2ae92010-11-11 23:22:19 +00003276- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
3277 can be set to False to turn off the previously undocumented 'popularity'
3278 heuristic. Patch by Terry Reedy and Eli Bendersky
3279
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003280- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3281 falling into recursion.
3282
R. David Murray7c4bf552010-08-25 01:45:57 +00003283- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3284 character years even if the message contains RFC822 two character years.
3285
Daniel Stutzbach91287322010-08-24 21:09:30 +00003286- Issue #8750: Fixed MutableSet's methods to correctly handle
3287 reflexive operations, namely x -= x and x ^= x.

Raymond Hettinger917bba12010-08-22 08:01:58 +00003297- Issue #9214: Set operations on KeysView or ItemsView in the collections
3298 module now correctly return a set. (Patch by Eli Bendersky.)
3299
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003300- Issue #9617: Signals received during a low-level write operation aren't
3301 ignored by the buffered IO layer anymore.
3302
Benjamin Peterson52c36052010-08-21 03:03:22 +00003303- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3304 are not held onto after they are deleted elsewhere.
3305
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003306- Issue #9626: the view methods for collections.OrderedDict() were returning
3307 the unordered versions inherited from dict. Those methods are now
3308 overridden to provide ordered views.
3309
Éric Araujo0389ae62010-08-14 03:07:46 +00003310- Issue #8688: MANIFEST files created by distutils now include a magic

3313
Antoine Pitroue1436d12010-08-12 15:25:51 +00003314- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3315 and a BadZipfile error is raised if it doesn't match (as used to be the
3316 case in Python 2.5 and earlier).
3317
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003318- Issue #9550: a BufferedReader could issue an additional read when the
3319 original read request had been satisfied, which could block indefinitely
3320 when the underlying raw IO channel was e.g. a socket. Report and original
3321 patch by Jason V. Miller.
3322
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003323- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00003341- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
3342 This is how it is supposed to work, wget and curl do the same. Previous
3343 behavior was wrong.

3351 the option character for the added 'h/help' option if prefix_chars
3352 does not contain a '-', instead of raising an error.
3353

3712 of the number of bytes specified by the start byte.
3713 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3714 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

3725 objects. (1) The comparison could incorrectly return True in some cases
3726 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004071 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4072 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4073 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4094-----------------
4095
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004096- Issue #7301: Add environment variable $PYTHONWARNINGS.
4097
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004098- Issue #8329: Don't return the same lists from select.select when no fds are
4099 changed.
4100
Georg Brandlfee0f442010-05-22 21:26:21 +00004101- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004102 on 64-bit machines. The shift count for either left or right shift is
4103 permitted to be up to sys.maxsize.
4104
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004105- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00004107- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004108
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004109- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4110
Georg Brandlfee0f442010-05-22 21:26:21 +00004111- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4112 with a non-empty format string. This is an effort to future-proof user
4113 code. If a derived class does not currently implement __format__ but later
4114 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004115 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004116 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004117
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004118- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00004131- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004132 (SIGINT). If an error occurs while importing the site module, the error is

4148
Georg Brandlfee0f442010-05-22 21:26:21 +00004149- Issue #8257: The Decimal construct now accepts a float instance directly,
4150 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004151
4152 >>> Decimal(1.1)
4153 Decimal('1.100000000000000088817841970012523233890533447265625')
4154
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004155- collections.Counter() now supports a subtract() method.
4156
Georg Brandlfee0f442010-05-22 21:26:21 +00004157- The functools module now has a total_ordering() class decorator to simplify
4158 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004159
Georg Brandlfee0f442010-05-22 21:26:21 +00004160- The functools module also adds cmp_to_key() as a tool to transition old-style
4161 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004162
Georg Brandlfee0f442010-05-22 21:26:21 +00004163- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4164 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004165
Georg Brandlfee0f442010-05-22 21:26:21 +00004166- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4167 InvalidOperation instead of returning False. (Comparisons involving a quiet
4168 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4169 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004170
Georg Brandlfee0f442010-05-22 21:26:21 +00004171- Issue #2531: Comparison operations between floats and Decimal instances now
4172 return a result based on the numeric values of the operands; previously they
4173 returned an arbitrary result based on the relative ordering of id(float) and
4174 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004175
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004176- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004177 argument `-` which tells it to read files to compile from stdin. Each line is
4178 read on demand and the named file is compiled immediately. (Original patch by
4179 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00004184- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4185 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004186 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004187
Georg Brandlfee0f442010-05-22 21:26:21 +00004188- Comparisons using one of <, <=, >, >= between a complex instance and a
4189 Fractions instance now raise TypeError instead of returning True/False. This
4190 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4191 <=> complex, and complex <=> complex comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004298 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4299 inconsistent: __int__ was used for some integer codes but not for others, and
4300 the set of integer codes for which it was used differed between native packing
4301 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004609 file position when calling `truncate()`. It would previously change the file
4610 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004611 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4612

4614 class used to represent files stored inside an archive. The new
4615 implementation is significantly faster and can be wrapped in a
4616 ``io.BufferedReader`` object for more speedups. It also solves an issue
4617 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004628- Issue #7748: Since unicode values are supported for some metadata options in
4629 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4630 encoded string for them. This ensures that the upload and register commands
4631 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004901- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4902 decimal string that's guaranteed to round back to x under correct rounding
4903 (with round-half-to-even rounding mode). Previously it gave a string based on
4904 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4905 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4906 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004907
Georg Brandlba83f822010-03-14 09:50:54 +00004908- Issue #7117: On almost all platforms: float-to-string and string-to-float
4909 conversions within Python are now correctly rounded. Places these conversions
4910 occur include: str for floats and complex numbers; the float and complex
4911 constructors; old-style and new-style numeric formatting; serialization and
4912 deserialization of floats and complex numbers using marshal, pickle and json;
4913 parsing of float and imaginary literals in Python code; Decimal-to-float
4914 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004915
Georg Brandlba83f822010-03-14 09:50:54 +00004916 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4917 providing correctly-rounded strtod and dtoa C functions. This code is
4918 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4919 the C compiler. There may be a small number of platforms on which correct
4920 operation of this code cannot be guaranteed, so the code is not used: notably,
4921 this applies to platforms where the C double format is not IEEE 754 binary64,
4922 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4923 and Python's configure script is unable to determine how to change the FPU
4924 precision. On these platforms conversions use the platform strtod and dtoa,
4925 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004927- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4928 uses the correctly-rounded string <-> float conversions described above (when
4929 available), and so produces correctly rounded results that will display nicely
4930 under the float repr. There are two related small changes: (1) round now
4931 accepts any class with an ``__index__()`` method for its second argument (but
4932 no longer accepts floats for the second argument), and (2) an excessively
4933 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4934 raises an exception.

5084 of 12. Previously, the behavior the same but with a default precision of 6.
5085 This more closely matches ``str()``, and reduces surprises when adding

5284
Georg Brandlba83f822010-03-14 09:50:54 +00005285- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5286 file objects with closefd=False. The file descriptor is still kept open but
5287 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00005311- On windows, ``os.chdir()`` given unicode was not working if
5312 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5313 this code path is really executed because I cannot move to such directory on
5314 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005316- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5317 element is temporarily replaced with an equivalent frozenset. But the
5318 eventual KeyError would always report the empty ``frozenset()`` as the missing

5340 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5341 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5342 of using the replace error handler in PyUnicode_DecodeUTF8().
5343
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005344- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00005347- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5349 gives improved memory leak detection when running under Valgrind, while taking
5350 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00005419- Issue #6816: runpy now provides a run_path function that allows Python code to
5420 execute file paths that refer to source or compiled Python files as well as
5421 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00005422 __main__.py file. This allows applications that run other Python scripts to
5423 support the same flexibility as the CPython command line itself.

5448 from stdin so that existing input does not confuse it and lead to incorrect
5449 entry or an IOError. It also properly flushes it afterwards to avoid the
5450 terminal echoing the input afterwards on OSes such as Solaris.

Georg Brandlba83f822010-03-14 09:50:54 +00006174 the timestamp in the gzip stream. The default value remains the current time.

6719
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006720- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6721 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6722 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6723 ``printf`` function, whereas PyString_FromFormat has an independent
6724 implementation and uses "%zd" on all platforms for size_t values.
6725 This makes a difference on win64, where ``printf`` needs "%Id" to display
6726 64bit values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006745- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006746 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6747 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6749 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6750 type object.

6847
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006848- Issue #2975: When compiling several extension modules with Visual Studio 2008
6849 from the same python interpreter, some environment variables would grow
6850 without limit.
6851
Benjamin Peterson37346b22008-08-23 20:27:43 +00006852- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006889What's New in Python 2.6 beta 3?
6890================================
6891
Barry Warsaw07a4a382008-08-21 01:15:08 +00006892*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006893
6894Core and Builtins
6895-----------------
6896
Guido van Rossumf8402962008-08-20 15:01:50 +00006897- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6898 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6899 extensions do not automatically benefit from the class attribute
6900 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6901 to their tp_flags field if they care. This is a backwards
6902 compatibility feature; in 3.0, all types will use the cache by
6903 default.
6904
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006905- Keyword arguments can now follow starred arguments. (``f(a, *args,
6906 keyword=23)`` is now valid syntax.)
6907
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006908- ctypes function pointers that are COM methods have a boolean True
6909 value again.
6910
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006911- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6912 by denying s# to parse objects that have a releasebuffer procedure,
6913 and introducing s*.
6914
Georg Brandl1e13ea92008-08-11 09:07:59 +00006915- Issue #3537: Fix an assertion failure when an empty but presized dict
6916 object was stored in the freelist.
6917
Mark Dickinsonb6467572008-08-04 21:30:09 +00006918- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6919 ValueError consistently across platforms.
6920
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006921- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6922 (64bit Unix, for example), unichr() would truncate its argument and return
6923 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6924
Neal Norwitze7d8be82008-07-31 17:17:14 +00006925- Apply security patches from Apple.
6926
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006927- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6928 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6929
Antoine Pitrou92f82162008-07-25 22:22:08 +00006930- Issue #1819: function calls with several named parameters are now on
6931 average 35% faster (as measured by pybench).
6932
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006933- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6934 the python debugger steps into a class statement: the free variables (local
6935 variables defined in an outer scope) would be deleted from the outer scope.
6936
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006937- Issue #2620: Overflow checking when allocating or reallocating memory
6938 was not always being done properly in some python types and extension
6939 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6940 all been updated to perform better checks and places in the code that
6941 would previously leak memory on the error path when such an allocation
6942 failed have been fixed.
6943
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006944Library
6945-------
6946
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006947- Issue #3612: Added some missing basic types in ctypes.wintypes.
6948
Benjamin Petersone977ad42008-08-20 01:42:01 +00006949- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6950 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6951
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006952- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6953 version reported by these tools does not necessarily follow the python
6954 version numbering scheme, so the module is less strict when parsing it.
6955
Nick Coghlanf70385a2008-08-18 12:42:46 +00006956- Issue #2235: Added Py3k warnings for types which will become unhashable
6957 under the stricter __hash__ inheritance rules in 3.0. Several types
6958 which did not meet the rules for hash invariants and were already
6959 unhashable in 3.0 have now been explicitly flagged as unhashable in
6960 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6961 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6962
Brett Cannon88f801d2008-08-18 00:46:22 +00006963- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6964 imported into the module but exposed as part of the module's API.
6965
Brett Cannon7b96f072008-08-18 00:41:11 +00006966- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6967
Brett Cannon46225e72008-08-18 00:36:52 +00006968- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006970- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6971
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006972- Issue #3575: Incremental decoder's decode function now takes bytearray
6973 by using 's*' instead of 't#'.
6974
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006975- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006976 fails unicode conversion on 2nd parameter. (windows only)
6977
Georg Brandl222e2082010-08-01 22:27:39 +00006978- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006979 in a redirect.
6980
Brett Cannonabe423e2008-08-16 21:47:07 +00006981- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006982 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006983
Facundo Batistaeb90b782008-08-16 14:44:07 +00006984- Issue #2776: fixed small issue when handling an URL with double slash
6985 after a 302 response in the case of not going through a proxy.
6986
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006987- Issue #2676: in the email package, content-type parsing was hanging on
6988 pathological input because of quadratic or exponential behaviour of a
6989 regular expression.
6990
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006991- Issue #3476: binary buffered reading through the new "io" library is now
6992 thread-safe.
6993
Brett Cannonbf3157b2008-08-14 05:00:03 +00006994- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6995 since mimetools itself is deprecated. Because modules are cached, all
6996 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6997
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006998- Issue #3134: shutil referenced undefined WindowsError symbol.
6999
Robert Schuppenies14646332008-08-10 11:01:53 +00007000- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7001 menu entries were not deleted.
7002
Brett Cannon83e81842008-08-09 23:30:55 +00007003- Copied the implementation of reduce() to _functools.reduce() to have a
7004 version that did not raise a DeprecationWarning under -3.
7005
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007006- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7007 a MemoryError rather than silently stop the iteration.
7008
Guido van Rossum59ce9012008-08-09 14:55:34 +00007009- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7010 to _sre.compile() will now be rejected. This should not affect anybody
7011 since the re.compile() function never generates invalid re-bytecode.
7012
Skip Montanaroa032bf42008-08-08 22:52:51 +00007013- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7014 upon first access it can be automatically initialized from the csv file if
7015 it wasn't initialized during instantiation.
7016
Brett Cannon3aa2a492008-08-06 22:28:09 +00007017- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7018 the reload() built-in has been removed.
7019
Brett Cannon7e30b672008-08-04 21:52:25 +00007020- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007021 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7029 raised an AttributeError.
7030
Benjamin Peterson01a24322008-07-28 23:35:27 +00007031- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007032 asking for a specific length. This problem only affected files opened
7033 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007034
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007035- Issue #3449: Update decimal module to use most recent specification

7059 file name rather than a ZipInfo instance, so files are extracted with
7060 mode 0600 rather than 000 under Unix.
7061
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007062- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7063 argument in python 2.5, this broke code that subclassed Popen to include its
7064 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7075 interaction with the tp_hash slot (added in 2.6b2) are now documented
7076
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007077- Issue #643841: The language reference now provides more detailed
7078 coverage of the lookup process for special methods. The disclaimers
7079 regarding lack of coverage of new-style classes have also been
7080 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007083What's New in Python 2.6 beta 2?
7084================================
7085
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007086*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007088Core and Builtins
7089-----------------
7090
Georg Brandl3e483f62008-07-16 22:57:41 +00007091- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7092 its methods now allow for items objects that can be converted to
7093 an integer using operator.index().
7094
Mark Dickinson64b7e502008-07-16 09:40:03 +00007095- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7096 produced a ValueError instead of giving the correct float.
7097
Eric Smitha5fa5a22008-07-16 00:11:49 +00007098- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7099 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7100
Mark Dickinson7103aa42008-07-15 19:08:33 +00007101- Issue #3008: the float type has a new instance method 'float.hex'
7102 and a new class method 'float.fromhex' to convert floating-point
7103 numbers to and from hexadecimal strings, respectively.
7104
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007105- Issue #2235: __hash__ is once again inherited by default. To allow
7106 collections.Hashable to remain meaningful in the presence of the
7107 default hash implementation (object.__hash__), it is now possible
7108 to explicit block inheritance of hash by setting __hash__=None at
7109 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7110 level.
7111
Nick Coghlanb028f502008-07-13 14:52:36 +00007112- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7113 the parent module cannot be found while performing an absolute import.
7114 This means that an incorrectly defined __package__ attribute will
7115 now only prevent relative imports in that module rather than causing

Georg Brandl5cc774e2008-06-11 20:28:06 +00007587 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007588

Georg Brandl3ee81df2008-05-17 18:14:43 +00007648- Issue #1631171: Re-implement the 'warnings' module in C (the
7649 original Python code has been kept as backup). This will allow for
7650 using the 'warning's machinery in such places as the parser where
7651 use of pure Python code is not possible. Both the ``showarning()``
7652 and ``formatwarning()`` gain an optional 'line' argument which is
7653 not called by default for backwards-compatibility reasons. Setting
7654 ``warnings.showwarning()`` to an implementation that lacks support
7655 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007718- Issue #2550: The approach used by client/server code for obtaining
7719 ports to listen on in network-oriented tests has been refined in an
7720 effort to facilitate running multiple instances of the entire
7721 regression test suite in parallel without issue.
7722 test_support.bind_port() has been fixed such that it will always
7723 return a unique port -- which wasn't always the case with the
7724 previous implementation, especially if socket options had been set
7725 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7726 new implementation of bind_port() will actually raise an exception
7727 if it is passed an AF_INET/SOCK_STREAM socket with either the
7728 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7729 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7730 the socket it's been passed. This currently only applies to
7731 Windows. This option prevents any other sockets from binding to the
7732 host/port we've bound to, thus removing the possibility of the
7733 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7734 when a second SOCK_STREAM socket binds and accepts to a host/port
7735 that's already been bound by another socket. The optional preferred
7736 port parameter to bind_port() has been removed. Under no
7737 circumstances should tests be hard coding ports!
7738
7739 test_support.find_unused_port() has also been introduced, which will
7740 pass a temporary socket object to bind_port() in order to obtain an
7741 unused port. The temporary socket object is then closed and
7742 deleted, and the port is returned. This method should only be used
7743 for obtaining an unused port in order to pass to an external program
7744 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7745 a parameter to a server-oriented class that doesn't give you direct
7746 access to the underlying socket used.
7747
7748 Finally, test_support.HOST has been introduced, which should be used
7749 for the host argument of any relevant socket calls (i.e. bind and
7750 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007751
7752 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007753 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007754 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7755 test_asynchat and test_socket_ssl.
7756
Georg Brandl3ee81df2008-05-17 18:14:43 +00007757 It is now possible for multiple instances of the regression test
7758 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008037- Added the future_builtins module, which contains hex() and oct().
8038 These are the PEP 3127 version of these functions, designed to be
8039 compatible with the hex() and oct() builtins from Python 3.0. They
8040 differ slightly in their output formats from the existing, unchanged
8041 Python 2.6 builtins. The expected usage of the future_builtins
8042 module is:
8043 from future_builtins import hex, oct
8044
Eric Smith7ef40bf2008-02-20 23:34:22 +00008045- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8046 exponents for exponents with absolute value < 100. Follows C99
8047 standard. This is a change on Windows, which would use 3 digits.
8048 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8049 so that any alterations it does to the resulting string will be
8050 available in stringlib/formatter.h (for float.__format__).
8051
Eric Smith5a3c1352008-02-19 13:21:56 +00008052- Implemented PEP 3101, Advanced String Formatting. This adds a new
8053 builtin format(); a format() method for str and unicode; a
8054 __format__() method to object, str, unicode, int, long, float, and
8055 datetime; the class string.Formatter; and the C API
8056 PyObject_Format().
8057
Georg Brandl3ee81df2008-05-17 18:14:43 +00008058- Fixed several potential crashes, all caused by specially crafted
8059 __del__ methods exploiting objects in temporarily inconsistent
8060 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008061
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008062- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008063 prevent a possible crash: an Abstract Base Class would try to access
8064 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008065

Georg Brandl3ee81df2008-05-17 18:14:43 +00008069- Clear all free lists during a gc.collect() of the highest generation
8070 in order to allow pymalloc to free more arenas. Python may give back
8071 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008072
Georg Brandl3ee81df2008-05-17 18:14:43 +00008073- Issue #2045: Fix an infinite recursion triggered when printing a
8074 subclass of collections.defaultdict, if its default_factory is set
8075 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008076
Christian Heimesf75dbef2008-02-08 00:11:31 +00008077- Fixed a minor memory leak in dictobject.c. The content of the free
8078 list was not freed on interpreter shutdown.
8079
Georg Brandl21e99f42010-03-07 15:23:59 +00008080- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00008082
Georg Brandl3ee81df2008-05-17 18:14:43 +00008083- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8084 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008085 to compact the internal free lists of pre-allocted ints and floats.
8086
Georg Brandl3ee81df2008-05-17 18:14:43 +00008087- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8088 calls. Python expected the return type int but the fork familie
8089 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008090
Georg Brandl3ee81df2008-05-17 18:14:43 +00008091- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8092 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008103- Patch #1473257: generator objects gain a gi_code attribute. This is
8104 the same object as the func_code attribute of the function that
8105 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008106
Georg Brandl3ee81df2008-05-17 18:14:43 +00008107- Issue #1920: "while 0" statements were completely removed by the
8108 compiler, even in the presence of an "else" clause, which is
8109 supposed to be run when the condition is false. Now the compiler
8110 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008111
Guido van Rossumeead05f2008-01-24 18:21:02 +00008112- A few crashers fixed: weakref_in_del.py (issue #1377858);
8113 loosing_dict_ref.py (issue #1303614, test67.py);
8114 borrowed_ref_[34].py (not in tracker).
8115
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008116- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008117 suppressed while an extension is loaded by calling SetErrorMode in

8119
Georg Brandl3ee81df2008-05-17 18:14:43 +00008120- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008121 several extension methods and modules do not work without unicode
8122 support.
8123
Georg Brandl26543b12008-01-21 18:36:51 +00008124- Issue #1882: when compiling code from a string, encoding cookies in the
8125 second line of code were not always recognized correctly.
8126
Georg Brandl14404b62008-01-19 19:27:05 +00008127- Issue #1679: "0x" was taken as a valid integer literal.
8128
Georg Brandl6caad7d2008-01-26 14:19:22 +00008129- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008130 added.
8131
Christian Heimesc94e2b52008-01-14 04:13:37 +00008132- sys.float_info / PyFloat_GetInfo: The floating point information
8133 object was converted from a dict to a specialized structseq object.
8134
Georg Brandl3ee81df2008-05-17 18:14:43 +00008135- Patch #1816: Added sys.flags structseq. It exposes the status of
8136 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008137
Georg Brandl3ee81df2008-05-17 18:14:43 +00008138- Objects/structseq.c: Implemented new structseq representation. The

8140 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008141
Georg Brandl3ee81df2008-05-17 18:14:43 +00008142- Patch #1700288: added a type attribute cache that caches method

Christian Heimes0a8143f2007-12-18 23:22:54 +00008166
Georg Brandl3ee81df2008-05-17 18:14:43 +00008167- Compiler now generates simpler and faster code for dictionary
8168 literals. The oparg for BUILD_MAP now indicates an estimated
8169 dictionary size. There is a new opcode, STORE_MAP, for adding
8170 entries to the dictionary.

8213
Georg Brandl21e99f42010-03-07 15:23:59 +00008214- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008215 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8216 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008217
Georg Brandl3ee81df2008-05-17 18:14:43 +00008218- Issue #1686386: Tuple's tp_repr did not take into account the
8219 possibility of having a self-referential tuple, which is possible
8220 from C code. Nor did object's tp_str consider that a type's tp_str
8221 could do something that could lead to an inifinite recursion.
8222 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8223 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008225- Issue #1164: It was possible to trigger deadlock when using the
8226 'print' statement to write to a file since the GIL was not released
8227 as needed. Now PyObject_Print() does the right thing along with
8228 various tp_print implementations of the built-in types and those in
8229 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00008238- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008239 PyObject_Call() never calling back out to Python code to trigger
8240 recursion depth updates/checks. Required the creation of a static
8241 RuntimeError instance in case normalizing an exception put the
8242 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00008259 __*__ attributes. (Some already existed, e.g., __doc__ and
8260 __name__.)

8266 calls.
8267
Collin Winter62903052007-05-18 23:11:24 +00008268- except clauses may now be spelled either "except E, target:" or

8270 with Python 3.0.

8290
Guido van Rossum143b5642007-03-23 04:58:42 +00008291- Bug #1683368: The object.__init__() and object.__new__() methods are
8292 now stricter in rejecting excess arguments. The only time when
8293 either allows excess arguments is when it is not overridden and the
8294 other one is. For backwards compatibility, when both are
8295 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008296 warning later). Also, type.__init__() insists on the same signature
8297 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008299- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8300 object to complex using its __complex__() method before falling back
8301 to the __float__() method. Therefore, the functions in the cmath
8302 module now can operate on objects that define a __complex__()
8303 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008321- Bug #1678647: write a newline after printing an exception in any
8322 case, even when converting the value to a string failed.
8323
Georg Brandl871f1bc2007-03-12 13:17:36 +00008324- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008325 its argument, if it exists. If not, it will work like before. This
8326 allows customizing the output of dir() in the presence of a
8327 __getattr__().

8337 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008338
Georg Brandlaa2321b2007-03-07 00:40:28 +00008339- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008340 makes the filenames the warning module prints much more sensible
8341 when a PYTHONSTARTUP file is used.

8356
Georg Brandl3ee81df2008-05-17 18:14:43 +00008357- When printing an unraisable error, don't print exceptions. before

Georg Brandl4e933132006-09-06 20:05:58 +00008442- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

8924
Georg Brandl92a6bae2007-03-13 17:43:32 +00008925- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008926 are set for invalid interpolation sequences that would lead to

8983 TestCase and TestSuite subclasses (not instances) are no longer
8984 accepted in TestSuite.addTest(). This should cause no
8985 incompatibility since it never made sense with ordinary subclasses
8986 -- the failure just occurred later, with a more cumbersome
8987 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009262- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9263 with RFC 3207 and forgets any knowledge obtained from the server not
9264 obtained from the TLS negotiation itself. Patch contributed by Bill
9265 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009266
Georg Brandl3ee81df2008-05-17 18:14:43 +00009267- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009268 that the SMTP.starttls() caller no longer needs to call ehlo()
9269 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009270 does not claim to support starttls. Adds the
9271 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9272 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009326- itertools.chain() now has an alternate constructor,

9352 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9353 silently miscode subclasses of those types. Now, it raises a
9354 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009355

Georg Brandl3ee81df2008-05-17 18:14:43 +00009370 time so that opening a database previously created with the DB_DUP
9371 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9372 opens. Specifically: dictionary assignment to a DB object will
9373 replace all values for a given key when the database allows
9374 duplicate values. DB users should use DB.put(k, v) when they want
9375 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009376

9382 characters with ASCII value less than 32. Also, it correctly quotes
9383 dots only if they occur on a single line, as opposed to the previous
9384 behavior of quoting dots if they are the second character of any
9385 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009386
Georg Brandla47337f2007-03-13 12:34:25 +00009387- Bug #1622896: fix a rare corner case where the bz2 module raised an

9653
Guido van Rossum7c862f82007-12-13 20:50:10 +00009654- Bug #1608: use -fwrapv when GCC supports it. This is important,
9655 newer GCC versions may optimize away overflow buffer overflow checks
9656 without this option!

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009660- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00009661 periodic threadstate and signal checking in tight loops. By
9662 default, this option is turned-off. It should only be enabled in
9663 debugged, performance critical applications.

9718 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009719
Georg Brandl3ee81df2008-05-17 18:14:43 +00009720- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9721 to ``PyTuple_SetItem``, it can be used to populate a brand new
9722 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009723

9734
Georg Brandl3ee81df2008-05-17 18:14:43 +00009735- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9736 of w# format code incorrectly truncated the length to an int, even
9737 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9738 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009739
Georg Brandl3ee81df2008-05-17 18:14:43 +00009740- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9760
9761- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9762 outside of pystate.c and should not be necessary.
9763
Georg Brandl3ee81df2008-05-17 18:14:43 +00009764- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9765 absolute imports. In earlier versions they might have used relative
9766 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009767
Georg Brandl3ee81df2008-05-17 18:14:43 +00009768- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9769 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009770
Georg Brandl3ee81df2008-05-17 18:14:43 +00009771- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009794- Removed the macfs module. It had been deprecated since Python 2.5.
9795 This lead to the deprecation of macostools.touched() as it relied
9796 solely on macfs and was a no-op under OS X.
