Mark Dickinsondbbed042011-09-19 16:38:08 +010094- Issue #12973: Fix overflow checks that invoked undefined behaviour in
95 int.__pow__. These overflow checks were causing int.__pow__ to produce
96 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010097 compiler optimizing the check away. Also fix similar overflow checks
98 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
99 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +0200110- Issue #12149: Update the method cache after a type's dictionnary gets
111 cleared by the garbage collector. This fixes a segfault when an instance
112 and its type get caught in a reference cycle, and the instance's
113 deallocator calls one of the methods on the type (e.g. when subclassing
114 IOBase). Diagnosis and patch by Davide Rizzo.

Victor Stinner08563d92011-05-30 23:44:13 +0200123 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
124 raw_input() interrupted by CTRL+c.
125
Łukasz Langa7a153902011-10-18 17:16:00 +0200126- Issue #10860: httplib now correctly handles an empty port after port
127 delimiter in URLs.
128

Florent Xiclunac2279652012-02-12 14:49:03 +0100167- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100168 has left two versions of customize_compiler, the original in
169 distutils.sysconfig and another copy in distutils.ccompiler, with some
170 parts of distutils calling one and others using the other.
171 Complete the revert back to only having one in distutils.sysconfig as
172 is the case in 3.x.
173
Ned Deily0d0ea482012-02-10 12:59:06 +0100174- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
175 Distutils-based packages with C extension modules may fail because
176 Apple has removed gcc-4.2, the version used to build python.org
177 64-bit/32-bit Pythons. If the user does not explicitly override
178 the default C compiler by setting the CC environment variable,
179 Distutils will now attempt to compile extension modules with clang
180 if gcc-4.2 is required but not found. Also as a convenience, if
181 the user does explicitly set CC, substitute its value as the default
182 compiler in the Distutils LDSHARED configuration variable for OS X.
183 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
184 SDK, neither of which are available in Xcode 4. This change does not
185 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700458- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
459 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
460 interpreter process. This could cause failures in non-Distutils subprocesses
461 and was unreliable since tests or user programs could modify the interpreter
462 environment after Distutils set it. Instead, have Distutils set the the
463 deployment target only in the environment of each build subprocess. It is
464 still possible to globally override the default by setting
465 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
466 greater or equal to the default value, the value with which the interpreter
467 was built.

Barry Warsawc5643282011-07-19 17:06:30 -0400495- sys.setcheckinterval() now updates the current ticker count as well as
496 updating the check interval, so if the user decreases the check interval,
497 the ticker doesn't have to wind down to zero from the old starting point
498 before the new interval takes effect. And if the user increases the
499 interval, it makes sure the new limit takes effect right away rather have an
500 early task switch before recognizing the new interval.

1445 This prevents user-created self-referencing ordered dictionaries from
1446 becoming permanently uncollectable GC garbage. The downside is that

1907
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001908- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1909 start byte and the continuation byte(s) are now considered invalid, instead
1910 of the number of bytes specified by the start byte.
1911 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1912 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1913 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1914 Previous versions returned a single u'\ufffd'.

1918 arises from the "Overriding __eq__ blocks inheritance ..." warning
1919 when turned into an exception: in this case the exception simply
1920 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001922- Issue #8748: Fix two issues with comparisons between complex and integer
1923 objects. (1) The comparison could incorrectly return True in some cases
1924 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1925 (2) The comparison raised an OverflowError for large integers, leading
1926 to unpredictable exceptions when combining integers and complex objects
1927 in sets or dicts.
1928
Mark Dickinson81336372010-05-30 12:12:25 +00001929- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00002066- Issue #1533: Fix inconsistency in range function argument processing: any
2067 non-float non-integer argument is now converted to an integer (if possible)
2068 using its __int__ method. Previously, only small arguments were treated this
2069 way; larger arguments (those whose __int__ was outside the range of a C long)
2070 would produce a TypeError.
Mark Dickinsona8d26682010-05-04 16:18:25 +00002071
Georg Brandlfee0f442010-05-22 21:26:21 +00002072- Issue #8202: ``sys.argv[0]`` is now set to '-m' instead of '-c' when searching

Georg Brandlfee0f442010-05-22 21:26:21 +00002078 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00002079 benefit compared to the dynamic memory allocation fallback. Patch by
2080 Charles-François Natali.

2090 on MacOS X. That is, ``python setup.py install --user`` will install into
2091 ``~/Library/Python/2.7`` instead of ``~/.local``.

Georg Brandlfee0f442010-05-22 21:26:21 +00002104- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
2105 messages when accessing undefined class attributes because of the cheap
2106 inheritance with the underlying socket object. The cheap inheritance has been
2107 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00002108
Georg Brandlfee0f442010-05-22 21:26:21 +00002109- Issue #4265: ``shutil.copyfile()`` was leaking file descriptors when disk

Georg Brandlfee0f442010-05-22 21:26:21 +00002120- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2121 operation raises multiple signals and more than one of those signals is
2122 trapped, the specification determines the order in which the signals should be
2123 handled. In many cases this order wasn't being followed, leading to the wrong
2124 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00002125
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +00002126- Issue #7865: The close() method of :mod:`io` objects should not swallow

2189 keywords.
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +00002190

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00002290
2291Core and Builtins
2292-----------------
2293
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002294- Issue #7301: Add environment variable $PYTHONWARNINGS.
2295
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002296- Issue #8329: Don't return the same lists from select.select when no fds are
2297 changed.
2298
Georg Brandlfee0f442010-05-22 21:26:21 +00002299- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002300 on 64-bit machines. The shift count for either left or right shift is
2301 permitted to be up to sys.maxsize.
2302
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002303- Ensure that tokenization of identifiers is not affected by locale.
2304
Georg Brandlfee0f442010-05-22 21:26:21 +00002305- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002306
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002307- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2308
Georg Brandlfee0f442010-05-22 21:26:21 +00002309- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2310 with a non-empty format string. This is an effort to future-proof user
2311 code. If a derived class does not currently implement __format__ but later
2312 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002313 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002314 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002315
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002316- Issue #8268: Old-style classes (not just instances) now support weak
2317 references.
2318
Georg Brandlfee0f442010-05-22 21:26:21 +00002319- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2320 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00002321
Victor Stinnerc7790ed2010-03-22 12:36:28 +00002322- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00002324- Issue #6474: Make error message from passing an inadequate number of keyword
2325 arguments to a function correct.
2326
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002327- Issue #8164: Don't allow lambda functions to have a docstring.
2328
Victor Stinner66644262010-03-10 22:30:19 +00002329- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002330 (SIGINT). If an error occurs while importing the site module, the error is
2331 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002332 module.
2333
Collin Winter001a3952010-03-18 21:54:01 +00002334- Code objects now support weak references.

2337-------
2338
R. David Murray661303f2010-04-13 20:57:40 +00002339- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
2340
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002341- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002342 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2343 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002344
Benjamin Peterson76a23c12010-04-04 23:23:22 +00002345- Issue #8310: Allow dis to examine new style classes.
2346
Georg Brandlfee0f442010-05-22 21:26:21 +00002347- Issue #8257: The Decimal construct now accepts a float instance directly,
2348 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002349
2350 >>> Decimal(1.1)
2351 Decimal('1.100000000000000088817841970012523233890533447265625')
2352
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002353- collections.Counter() now supports a subtract() method.
2354
Georg Brandlfee0f442010-05-22 21:26:21 +00002355- The functools module now has a total_ordering() class decorator to simplify
2356 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002357
Georg Brandlfee0f442010-05-22 21:26:21 +00002358- The functools module also adds cmp_to_key() as a tool to transition old-style
2359 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002360
Georg Brandlfee0f442010-05-22 21:26:21 +00002361- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2362 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002363
Georg Brandlfee0f442010-05-22 21:26:21 +00002364- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2365 InvalidOperation instead of returning False. (Comparisons involving a quiet
2366 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2367 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002368
Georg Brandlfee0f442010-05-22 21:26:21 +00002369- Issue #2531: Comparison operations between floats and Decimal instances now
2370 return a result based on the numeric values of the operands; previously they
2371 returned an arbitrary result based on the relative ordering of id(float) and
2372 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002373
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002374- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002375 argument `-` which tells it to read files to compile from stdin. Each line is
2376 read on demand and the named file is compiled immediately. (Original patch by
2377 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002378
Georg Brandlfee0f442010-05-22 21:26:21 +00002379- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2380 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002382- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2383 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002384 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002385
Georg Brandlfee0f442010-05-22 21:26:21 +00002386- Comparisons using one of <, <=, >, >= between a complex instance and a
2387 Fractions instance now raise TypeError instead of returning True/False. This
2388 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2389 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002390
Michael Foorde6410c52010-03-29 20:04:23 +00002391- Addition of ``WeakSet`` to the ``weakref`` module.

2399
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002400- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002401 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2402 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002403
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002404- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2405 deprecated.
2406
Georg Brandlfee0f442010-05-22 21:26:21 +00002407- Issue #7860: platform.uname now reports the correct 'machine' type when Python
2408 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00002409

2414 existing at the same time, causing a Unicode error when configuration code
2415 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00002416
Georg Brandlfee0f442010-05-22 21:26:21 +00002417- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
2418 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00002419
Antoine Pitroueee91cd2010-03-26 19:27:16 +00002420- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
2421 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
2422 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00002423
Florent Xiclunacf82fa62010-03-21 12:27:20 +00002424- Issue #8179: Fix macpath.realpath() on a non-existing path.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002444- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002445 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2446 log file to compute the next rollover time. If the log file does not exist,
2447 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002448
Georg Brandlba83f822010-03-14 09:50:54 +00002449- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

2456
Georg Brandlba83f822010-03-14 09:50:54 +00002457- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2458 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2459 This is a behavior change, so email's minor version number is now bumped, to
2460 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00002461

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002488- Issue #8300: When passing a non-integer argument to struct.pack with any
2489 integer format code, struct.pack first attempts to convert the non-integer
2490 using its __index__ method. If that method is non-existent or raises
2491 TypeError it goes on to try the __int__ method, as described below.
2492
Georg Brandlba83f822010-03-14 09:50:54 +00002493- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2494 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2495 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002496 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2497 inconsistent: __int__ was used for some integer codes but not for others, and
2498 the set of integer codes for which it was used differed between native packing
2499 and standard packing.)

2903Core and Builtins
2904-----------------
2905
Georg Brandlba83f822010-03-14 09:50:54 +00002906- The ``__complex__()`` method is now looked up on the class of instances to
2907 make it consistent with other special methods.

2911
Mark Dickinson1b34d252010-01-01 17:27:30 +00002912- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002913 DeprecationWarning when passed a float argument where an integer was expected.
2914 These functions and methods now raise TypeError instead. The majority of the
2915 effects of this change are in the extension modules, but some core functions
2916 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2917 and many unicode/str methods.

2931 of integers: the result of a/b is now correctly rounded for ints a and b (at
2932 least on IEEE 754 platforms), and in particular does not depend on the
2933 internal representation of a long.

2941
Georg Brandlba83f822010-03-14 09:50:54 +00002942 These executables now work properly with the arch(1) command: ``arch -ppc
2943 python`` will start a universal binary version of python in PPC mode (unlike

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003085

Georg Brandlba83f822010-03-14 09:50:54 +00003100- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3101 decimal string that's guaranteed to round back to x under correct rounding
3102 (with round-half-to-even rounding mode). Previously it gave a string based on
3103 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3104 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3105 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003106
Georg Brandlba83f822010-03-14 09:50:54 +00003107- Issue #7117: On almost all platforms: float-to-string and string-to-float
3108 conversions within Python are now correctly rounded. Places these conversions
3109 occur include: str for floats and complex numbers; the float and complex
3110 constructors; old-style and new-style numeric formatting; serialization and
3111 deserialization of floats and complex numbers using marshal, pickle and json;
3112 parsing of float and imaginary literals in Python code; Decimal-to-float
3113 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003114
Georg Brandlba83f822010-03-14 09:50:54 +00003115 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3116 providing correctly-rounded strtod and dtoa C functions. This code is
3117 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3118 the C compiler. There may be a small number of platforms on which correct
3119 operation of this code cannot be guaranteed, so the code is not used: notably,
3120 this applies to platforms where the C double format is not IEEE 754 binary64,
3121 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3122 and Python's configure script is unable to determine how to change the FPU
3123 precision. On these platforms conversions use the platform strtod and dtoa,
3124 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003126- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3127 uses the correctly-rounded string <-> float conversions described above (when
3128 available), and so produces correctly rounded results that will display nicely
3129 under the float repr. There are two related small changes: (1) round now
3130 accepts any class with an ``__index__()`` method for its second argument (but
3131 no longer accepts floats for the second argument), and (2) an excessively
3132 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3133 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003227- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
3228 build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
3229 of stdint.h on that platform.
Mark Dickinson2f865b92009-06-30 15:32:30 +00003230

Georg Brandlba83f822010-03-14 09:50:54 +00003252 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +00003253
Georg Brandlba83f822010-03-14 09:50:54 +00003254- Issue #5982: staticmethod and classmethod now expose the wrapped function with

3262
Georg Brandlba83f822010-03-14 09:50:54 +00003263- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
3264 consistent with float("1e500") and interpretation of real and imaginary
3265 literals.
Mark Dickinsona4e0efa2009-05-20 18:43:07 +00003266
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +00003267- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
3268

R. David Murray525cffc2009-05-13 13:07:14 +00003273
Mark Dickinsonb1d45852009-05-11 15:33:08 +00003274- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00003275
Georg Brandlba83f822010-03-14 09:50:54 +00003276 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3277 (2) parsing of strings representing infinities and nans was locale aware; and
3278 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00003279
Georg Brandlba83f822010-03-14 09:50:54 +00003280- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3281 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3282 but with at least one decimal point and with a default precision
3283 of 12. Previously, the behavior the same but with a default precision of 6.
3284 This more closely matches ``str()``, and reduces surprises when adding
3285 alignment flags to the empty presentation type. This also affects the new
3286 complex.__format__ in the same way.
3287
3288- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3289 classtype's, even if it was None. property now inserts the __doc__ into the
3290 subclass instance __dict__.

3309
Benjamin Peterson5083dc52009-04-25 00:41:22 +00003310- Issue #5283: Setting __class__ in __del__ caused a segfault.
3311
Georg Brandlba83f822010-03-14 09:50:54 +00003312- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves
3313 nans, infs or negative zeros.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00003350- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00003351 untrackable objects are not tracked by the garbage collector. This can reduce
3352 the size of collections and therefore the garbage collection overhead on
3353 long-running programs, depending on their particular use of datatypes.

3360 internal representation of integers, for performance reasons. Base 2**30 is
3361 enabled by default on 64-bit machines. Add --enable-big-digits option to
3362 configure, which overrides the default. Add sys.long_info structseq to
3363 provide information about the internal format.
Mark Dickinsonefc82f72009-03-20 15:51:55 +00003364

3470 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3471 instances. On a typical machine this saves 3 bytes of memory (on average) per

3483
Georg Brandlba83f822010-03-14 09:50:54 +00003484- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3485 file objects with closefd=False. The file descriptor is still kept open but
3486 the file object behaves like a closed file. The ``FileIO`` object also got a
3487 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003507- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003510- On windows, ``os.chdir()`` given unicode was not working if
3511 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3512 this code path is really executed because I cannot move to such directory on
3513 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003515- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3516 element is temporarily replaced with an equivalent frozenset. But the
3517 eventual KeyError would always report the empty ``frozenset()`` as the missing
3518 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003538- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3539 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3540 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3541 of using the replace error handler in PyUnicode_DecodeUTF8().
3542
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003543- Issue #3739: The unicode-internal encoder now reports the number of characters

3545
Georg Brandlba83f822010-03-14 09:50:54 +00003546- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3547 allocator will be automatically disabled when running under Valgrind. This
3548 gives improved memory leak detection when running under Valgrind, while taking
3549 advantage of pymalloc at other times.

4715 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4716 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4717 neither __int__ nor __long__, TypeError used to be raised (with a
4718 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and

4915
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004916- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4917 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4918 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4919 ``printf`` function, whereas PyString_FromFormat has an independent
4920 implementation and uses "%zd" on all platforms for size_t values.
4921 This makes a difference on win64, where ``printf`` needs "%Id" to display
4922 64bit values.

4928 object; previously an int would be returned for small values. the __long__
4929 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004939 was correctly parsed but parsing of subsequent arguments failed.
4940
Vinay Sajip35e3b032008-09-01 14:33:59 +00004941- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004942 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4943 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4944 when given a tuple of classes as second argument, were looking up
4945 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4946 type object.

5091-----------------
5092
Guido van Rossumf8402962008-08-20 15:01:50 +00005093- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5094 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5095 extensions do not automatically benefit from the class attribute
5096 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5097 to their tp_flags field if they care. This is a backwards
5098 compatibility feature; in 3.0, all types will use the cache by
5099 default.
5100
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005101- Keyword arguments can now follow starred arguments. (``f(a, *args,

5103
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005104- ctypes function pointers that are COM methods have a boolean True
5105 value again.

5115 ValueError consistently across platforms.
5116
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005117- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5118 (64bit Unix, for example), unichr() would truncate its argument and return
5119 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00005121- Apply security patches from Apple.
5122
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005123- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5124 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5125
Antoine Pitrou92f82162008-07-25 22:22:08 +00005126- Issue #1819: function calls with several named parameters are now on
5127 average 35% faster (as measured by pybench).
5128
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005129- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5130 the python debugger steps into a class statement: the free variables (local
5131 variables defined in an outer scope) would be deleted from the outer scope.
5132
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005133- Issue #2620: Overflow checking when allocating or reallocating memory
5134 was not always being done properly in some python types and extension
5135 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5136 all been updated to perform better checks and places in the code that
5137 would previously leak memory on the error path when such an allocation
5138 failed have been fixed.

5144
Benjamin Petersone977ad42008-08-20 01:42:01 +00005145- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5146 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5147
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005148- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5149 version reported by these tools does not necessarily follow the python
5150 version numbering scheme, so the module is less strict when parsing it.
5151
Nick Coghlanf70385a2008-08-18 12:42:46 +00005152- Issue #2235: Added Py3k warnings for types which will become unhashable
5153 under the stricter __hash__ inheritance rules in 3.0. Several types
5154 which did not meet the rules for hash invariants and were already
5155 unhashable in 3.0 have now been explicitly flagged as unhashable in
5156 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5157 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5158
Brett Cannon88f801d2008-08-18 00:46:22 +00005159- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5160 imported into the module but exposed as part of the module's API.
5161

Antoine Pitroub90a8be2008-08-15 21:03:21 +00005183- Issue #2676: in the email package, content-type parsing was hanging on
5184 pathological input because of quadratic or exponential behaviour of a
5185 regular expression.
5186

5188 thread-safe.
5189
Brett Cannonbf3157b2008-08-14 05:00:03 +00005190- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5191 since mimetools itself is deprecated. Because modules are cached, all
5192 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5193
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005194- Issue #3134: shutil referenced undefined WindowsError symbol.

5203 a MemoryError rather than silently stop the iteration.
5204
Guido van Rossum59ce9012008-08-09 14:55:34 +00005205- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5206 to _sre.compile() will now be rejected. This should not affect anybody
5207 since the re.compile() function never generates invalid re-bytecode.
5208
Skip Montanaroa032bf42008-08-08 22:52:51 +00005209- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5210 upon first access it can be automatically initialized from the csv file if
5211 it wasn't initialized during instantiation.
5212
Brett Cannon3aa2a492008-08-06 22:28:09 +00005213- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5214 the reload() built-in has been removed.
5215
Brett Cannon7e30b672008-08-04 21:52:25 +00005216- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005217 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5225 raised an AttributeError.
5226
Benjamin Peterson01a24322008-07-28 23:35:27 +00005227- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005228 asking for a specific length. This problem only affected files opened
5229 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005230

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005254- Issue #3394: zipfile.writestr sets external attributes when passed a
5255 file name rather than a ZipInfo instance, so files are extracted with
5256 mode 0600 rather than 000 under Unix.
5257
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005258- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5259 argument in python 2.5, this broke code that subclassed Popen to include its
5260 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005270- Issue #2235: the C API function PyObject_HashNotImplemented and its
5271 interaction with the tp_hash slot (added in 2.6b2) are now documented
5272
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005273- Issue #643841: The language reference now provides more detailed
5274 coverage of the lookup process for special methods. The disclaimers
5275 regarding lack of coverage of new-style classes have also been
5276 removed, since the coverage is now fairly reasonable.

5280================================
5281
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005282*Release date: 17-Jul-2008*
5283
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005284Core and Builtins
5285-----------------
5286
Georg Brandl3e483f62008-07-16 22:57:41 +00005287- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5288 its methods now allow for items objects that can be converted to
5289 an integer using operator.index().
5290
Mark Dickinson64b7e502008-07-16 09:40:03 +00005291- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5292 produced a ValueError instead of giving the correct float.
5293
Eric Smitha5fa5a22008-07-16 00:11:49 +00005294- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5295 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5296
Mark Dickinson7103aa42008-07-15 19:08:33 +00005297- Issue #3008: the float type has a new instance method 'float.hex'
5298 and a new class method 'float.fromhex' to convert floating-point
5299 numbers to and from hexadecimal strings, respectively.
5300
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005301- Issue #2235: __hash__ is once again inherited by default. To allow
5302 collections.Hashable to remain meaningful in the presence of the
5303 default hash implementation (object.__hash__), it is now possible
5304 to explicit block inheritance of hash by setting __hash__=None at
5305 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5306 level.
5307
Nick Coghlanb028f502008-07-13 14:52:36 +00005308- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5309 the parent module cannot be found while performing an absolute import.
5310 This means that an incorrectly defined __package__ attribute will
5311 now only prevent relative imports in that module rather than causing
5312 all imports from that module to fail.
5313
Nick Coghlan14ff9942008-07-08 14:21:42 +00005314- Issue #2517: Allow unicode messages in Exceptions again by correctly
5315 bypassing the instance dictionary when looking up __unicode__ on
5316 new-style classes.
5317
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005318- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5319 set to a custom object whose write() method happens to install
5320 another file in sys.stdout.
5321
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005322- Issue #3088: Corrected a race condition in classes derived from
5323 threading.local: the first member set by a thread could be saved in
5324 another thread's dictionary.
5325
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005326- Issue #3004: Minor change to slice.indices(): the start and stop
5327 arguments are now treated identically, making the behaviour easier
5328 to describe and understand. For example, slice(None, -10,
5329 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5330 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5331 10, -1).
5332
Georg Brandl278fc502008-07-19 12:46:12 +00005333- Issue #3219: Calling a function with repeated keyword arguments,
5334 f(a=2, a=23), would not cause a syntax error. This was a regression
5335 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005336
Georg Brandl278fc502008-07-19 12:46:12 +00005337- Issue #2862: Make int and float freelist management consistent with
5338 other freelists. Changes their CompactFreeList apis into
5339 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005340

5342-------
5343
Thomas Heller57adf222008-08-14 19:10:48 +00005344- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5345 api functions without holding the GIL, which could lead to a fatal
5346 error when they failed.
5347
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005348- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5357 ForkingPickler.register() to resolve conflict with ctypes.
5358
Vinay Sajip51e65192008-07-18 09:01:10 +00005359- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00005361- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5362 a valid dlerror() message.
5363
Thomas Heller2bad6572008-07-15 17:19:50 +00005364- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5365 incomplete structure was created.
5366

5370
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005371- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005372
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005373- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5374 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005375 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005376 content-length. The problem had been corrected in the 2.4 branch, but never
5377 merged into trunk.
5378
Georg Brandle78fbcc2008-07-05 10:13:36 +00005379- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00005389- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005390 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005391
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005392- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5393 handling is now the same as that of other special attributes like __name__).
5394
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005395- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5396 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00005785 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005786
5787 This is controlled by the configure argument ``--with-universal-archs``:
5788
5789 - ``--with-universal-archs=all``: install 4-way universal
5790
5791 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5792
5793 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5794
5795 This option should be used in combination with ``--enable-universalsdk=``.
5796
5797 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 +00005847- Issue #1631171: Re-implement the 'warnings' module in C (the
5848 original Python code has been kept as backup). This will allow for
5849 using the 'warning's machinery in such places as the parser where
5850 use of pure Python code is not possible. Both the ``showarning()``
5851 and ``formatwarning()`` gain an optional 'line' argument which is
5852 not called by default for backwards-compatibility reasons. Setting
5853 ``warnings.showwarning()`` to an implementation that lacks support
5854 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005917- Issue #2550: The approach used by client/server code for obtaining
5918 ports to listen on in network-oriented tests has been refined in an
5919 effort to facilitate running multiple instances of the entire
5920 regression test suite in parallel without issue.
5921 test_support.bind_port() has been fixed such that it will always
5922 return a unique port -- which wasn't always the case with the
5923 previous implementation, especially if socket options had been set
5924 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5925 new implementation of bind_port() will actually raise an exception
5926 if it is passed an AF_INET/SOCK_STREAM socket with either the
5927 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5928 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5929 the socket it's been passed. This currently only applies to
5930 Windows. This option prevents any other sockets from binding to the
5931 host/port we've bound to, thus removing the possibility of the
5932 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5933 when a second SOCK_STREAM socket binds and accepts to a host/port
5934 that's already been bound by another socket. The optional preferred
5935 port parameter to bind_port() has been removed. Under no
5936 circumstances should tests be hard coding ports!
5937
5938 test_support.find_unused_port() has also been introduced, which will
5939 pass a temporary socket object to bind_port() in order to obtain an
5940 unused port. The temporary socket object is then closed and
5941 deleted, and the port is returned. This method should only be used
5942 for obtaining an unused port in order to pass to an external program
5943 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5944 a parameter to a server-oriented class that doesn't give you direct
5945 access to the underlying socket used.
5946
5947 Finally, test_support.HOST has been introduced, which should be used
5948 for the host argument of any relevant socket calls (i.e. bind and
5949 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005950
5951 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005952 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005953 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5954 test_asynchat and test_socket_ssl.
5955
Georg Brandl3ee81df2008-05-17 18:14:43 +00005956 It is now possible for multiple instances of the regression test
5957 suite to run in parallel without issue.

6223Core and builtins
6224-----------------
6225
Fred Drakea8ee94b2008-03-01 02:45:07 +00006226- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006227 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006228
Georg Brandlad61bc82008-02-23 15:11:18 +00006229- Issue #2067: file.__exit__() now calls subclasses' close() method.
6230
6231- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006232
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006233- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006234 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006235
Eric Smitha73fbe72008-02-23 03:09:44 +00006236- Added the future_builtins module, which contains hex() and oct().
6237 These are the PEP 3127 version of these functions, designed to be
6238 compatible with the hex() and oct() builtins from Python 3.0. They
6239 differ slightly in their output formats from the existing, unchanged
6240 Python 2.6 builtins. The expected usage of the future_builtins
6241 module is:
6242 from future_builtins import hex, oct
6243
Eric Smith7ef40bf2008-02-20 23:34:22 +00006244- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6245 exponents for exponents with absolute value < 100. Follows C99
6246 standard. This is a change on Windows, which would use 3 digits.
6247 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6248 so that any alterations it does to the resulting string will be
6249 available in stringlib/formatter.h (for float.__format__).
6250
Eric Smith5a3c1352008-02-19 13:21:56 +00006251- Implemented PEP 3101, Advanced String Formatting. This adds a new
6252 builtin format(); a format() method for str and unicode; a
6253 __format__() method to object, str, unicode, int, long, float, and
6254 datetime; the class string.Formatter; and the C API
6255 PyObject_Format().
6256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006257- Fixed several potential crashes, all caused by specially crafted
6258 __del__ methods exploiting objects in temporarily inconsistent
6259 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006260
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006261- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006262 prevent a possible crash: an Abstract Base Class would try to access
6263 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006264
Georg Brandl3ee81df2008-05-17 18:14:43 +00006265- Fixed repr() and str() of complex numbers with infinity or nan as
6266 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006267
Georg Brandl3ee81df2008-05-17 18:14:43 +00006268- Clear all free lists during a gc.collect() of the highest generation
6269 in order to allow pymalloc to free more arenas. Python may give back
6270 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006271
Georg Brandl3ee81df2008-05-17 18:14:43 +00006272- Issue #2045: Fix an infinite recursion triggered when printing a
6273 subclass of collections.defaultdict, if its default_factory is set
6274 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006275
Christian Heimesf75dbef2008-02-08 00:11:31 +00006276- Fixed a minor memory leak in dictobject.c. The content of the free
6277 list was not freed on interpreter shutdown.
6278
Georg Brandl21e99f42010-03-07 15:23:59 +00006279- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006280 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006281
Georg Brandl3ee81df2008-05-17 18:14:43 +00006282- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6283 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006284 to compact the internal free lists of pre-allocted ints and floats.
6285
Georg Brandl3ee81df2008-05-17 18:14:43 +00006286- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6287 calls. Python expected the return type int but the fork familie
6288 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006289
Georg Brandl3ee81df2008-05-17 18:14:43 +00006290- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6291 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006292
Georg Brandl3ee81df2008-05-17 18:14:43 +00006293- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6294 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006295
Georg Brandl3ee81df2008-05-17 18:14:43 +00006296- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6297 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006298
Georg Brandl3ee81df2008-05-17 18:14:43 +00006299- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6300 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006301
Georg Brandl3ee81df2008-05-17 18:14:43 +00006302- Patch #1473257: generator objects gain a gi_code attribute. This is
6303 the same object as the func_code attribute of the function that
6304 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006305
Georg Brandl3ee81df2008-05-17 18:14:43 +00006306- Issue #1920: "while 0" statements were completely removed by the
6307 compiler, even in the presence of an "else" clause, which is
6308 supposed to be run when the condition is false. Now the compiler
6309 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006310
Guido van Rossumeead05f2008-01-24 18:21:02 +00006311- A few crashers fixed: weakref_in_del.py (issue #1377858);
6312 loosing_dict_ref.py (issue #1303614, test67.py);
6313 borrowed_ref_[34].py (not in tracker).
6314
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006315- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006316 suppressed while an extension is loaded by calling SetErrorMode in
6317 dynload_win.c. The error is still reported properly.
6318
Georg Brandl3ee81df2008-05-17 18:14:43 +00006319- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006320 several extension methods and modules do not work without unicode
6321 support.
6322
Georg Brandl26543b12008-01-21 18:36:51 +00006323- Issue #1882: when compiling code from a string, encoding cookies in the
6324 second line of code were not always recognized correctly.
6325
Georg Brandl14404b62008-01-19 19:27:05 +00006326- Issue #1679: "0x" was taken as a valid integer literal.
6327
Georg Brandl6caad7d2008-01-26 14:19:22 +00006328- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006329 added.
6330
Christian Heimesc94e2b52008-01-14 04:13:37 +00006331- sys.float_info / PyFloat_GetInfo: The floating point information
6332 object was converted from a dict to a specialized structseq object.
6333
Georg Brandl3ee81df2008-05-17 18:14:43 +00006334- Patch #1816: Added sys.flags structseq. It exposes the status of
6335 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006336
Georg Brandl3ee81df2008-05-17 18:14:43 +00006337- Objects/structseq.c: Implemented new structseq representation. The
6338 patch makes structseqs (e.g. the return value of os.stat) more
6339 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006340
Georg Brandl3ee81df2008-05-17 18:14:43 +00006341- Patch #1700288: added a type attribute cache that caches method
6342 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006343
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006344- Bug #1776: __import__() no longer accepts filenames on any platform.
6345 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006346
Georg Brandlaed6c662008-01-07 17:25:53 +00006347- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6348
Georg Brandl3ee81df2008-05-17 18:14:43 +00006349- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6350 envvar and sys.dont_write_bytecode attribute. All these can be set
6351 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006352
Georg Brandl3ee81df2008-05-17 18:14:43 +00006353- Improve some exception messages when Windows fails to load an
6354 extension module. Now we get for example '%1 is not a valid Win32
6355 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006356
Georg Brandl3ee81df2008-05-17 18:14:43 +00006357- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006359- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6360 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006361
Christian Heimes0a8143f2007-12-18 23:22:54 +00006362- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006363 and INF. float("nan"), float("inf") and float("-inf") now work on
6364 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006365
Georg Brandl3ee81df2008-05-17 18:14:43 +00006366- Compiler now generates simpler and faster code for dictionary
6367 literals. The oparg for BUILD_MAP now indicates an estimated
6368 dictionary size. There is a new opcode, STORE_MAP, for adding
6369 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006370
Georg Brandl3ee81df2008-05-17 18:14:43 +00006371- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006376- Issue #1538: Avoid copying string in split/rsplit if the split char
6377 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006378
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006379- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006380 SystemError.
6381
Nick Coghlanef01d822007-12-03 12:55:17 +00006382- PEP 366: Allow explicit relative imports when executing modules
6383 inside packages with the -m switch via a new module level
6384 __package__ attribute.
6385
Georg Brandl3ee81df2008-05-17 18:14:43 +00006386- Issue #1402: Fix a crash on exit, when another thread is still
6387 running, and if the deallocation of its frames somehow calls the
6388 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006389

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006393 attribute of an empty cell object.
6394
Georg Brandl3ee81df2008-05-17 18:14:43 +00006395- Issue #1460: The utf-7 incremental decoder did not accept truncated
6396 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006397
Georg Brandl3ee81df2008-05-17 18:14:43 +00006398- Patch #1739468: Directories and zipfiles containing a __main__.py
6399 file can now be directly executed by passing their name to the
6400 interpreter. The directory/zipfile is automatically inserted as the
6401 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006402
Georg Brandl3ee81df2008-05-17 18:14:43 +00006403- Issue #1265: Fix a problem with sys.settrace, if the tracing
6404 function uses a generator expression when at the same time the
6405 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006406
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006407- sets and frozensets now have an isdisjoint() method.
6408
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006409- optimize the performance of builtin.sum().
6410
Neal Norwitz44f326e2007-10-05 05:29:17 +00006411- Fix warnings found by the new version of the Coverity checker.
6412
Georg Brandl21e99f42010-03-07 15:23:59 +00006413- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006414 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6415 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006416
Georg Brandl3ee81df2008-05-17 18:14:43 +00006417- Issue #1686386: Tuple's tp_repr did not take into account the
6418 possibility of having a self-referential tuple, which is possible
6419 from C code. Nor did object's tp_str consider that a type's tp_str
6420 could do something that could lead to an inifinite recursion.
6421 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6422 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006423
Georg Brandl3ee81df2008-05-17 18:14:43 +00006424- Issue #1164: It was possible to trigger deadlock when using the
6425 'print' statement to write to a file since the GIL was not released
6426 as needed. Now PyObject_Print() does the right thing along with
6427 various tp_print implementations of the built-in types and those in
6428 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006429
Georg Brandl3ee81df2008-05-17 18:14:43 +00006430- Issue #1147: Exceptions were directly allowing string exceptions in
6431 their throw() method even though string exceptions no longer
6432 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006433
Georg Brandl3ee81df2008-05-17 18:14:43 +00006434- Issue #1096: Prevent a segfault from getting the repr of a very
6435 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006436
Brett Cannon1e534b52007-09-07 04:18:30 +00006437- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006438 PyObject_Call() never calling back out to Python code to trigger
6439 recursion depth updates/checks. Required the creation of a static
6440 RuntimeError instance in case normalizing an exception put the
6441 recursion check value past its limit. Fixes crashers
6442 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006443
Georg Brandl3ee81df2008-05-17 18:14:43 +00006444- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006457- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006458 __*__ attributes. (Some already existed, e.g., __doc__ and
6459 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006460
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006461- Add -3 option to the interpreter to warn about features that are
6462 deprecated and will be changed/removed in Python 3.0.
6463

6465 calls.
6466
Collin Winter62903052007-05-18 23:11:24 +00006467- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006468 "except E as target:". This is to provide forwards compatibility
6469 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006470
Brett Cannon229cee22007-05-05 01:34:02 +00006471- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006476- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006477 setting a plain string, ie don't expand to single letter identifiers.
6478
Raymond Hettinger13936692007-04-11 18:40:58 +00006479- Request #1191699: Slices can now be pickled.

6489
Guido van Rossum143b5642007-03-23 04:58:42 +00006490- Bug #1683368: The object.__init__() and object.__new__() methods are
6491 now stricter in rejecting excess arguments. The only time when
6492 either allows excess arguments is when it is not overridden and the
6493 other one is. For backwards compatibility, when both are
6494 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006495 warning later). Also, type.__init__() insists on the same signature
6496 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006497
Georg Brandl3ee81df2008-05-17 18:14:43 +00006498- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6499 object to complex using its __complex__() method before falling back
6500 to the __float__() method. Therefore, the functions in the cmath
6501 module now can operate on objects that define a __complex__()
6502 method.

6519
Georg Brandl7b9c5552007-03-12 14:30:05 +00006520- Bug #1678647: write a newline after printing an exception in any
6521 case, even when converting the value to a string failed.
6522
Georg Brandl871f1bc2007-03-12 13:17:36 +00006523- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006524 its argument, if it exists. If not, it will work like before. This
6525 allows customizing the output of dir() in the presence of a
6526 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006527
Collin Winter276887b2007-03-12 16:11:39 +00006528- Patch #922167: Python no longer segfaults when faced with infinitely
6529 self-recursive reload() calls (as reported by bug #742342).

6535 parthensized forms. This means complex(repr(x)) now works instead of
6536 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006537
Georg Brandlaa2321b2007-03-07 00:40:28 +00006538- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006539 makes the filenames the warning module prints much more sensible
6540 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006541

Georg Brandl0fca97a2007-03-05 22:28:08 +00006553- Patch #1674228: when assigning a slice (old-style), check for the
6554 sq_ass_slice instead of the sq_slice slot.
6555
Georg Brandl3ee81df2008-05-17 18:14:43 +00006556- When printing an unraisable error, don't print exceptions. before
6557 the name. This duplicates the behavior whening normally printing
6558 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007091 AttributeError instead of an IOError when the server's response
7092 didn't contain a valid HTTP status line.

7183 TestCase and TestSuite subclasses (not instances) are no longer
7184 accepted in TestSuite.addTest(). This should cause no

7186 -- the failure just occurred later, with a more cumbersome

Georg Brandl3ee81df2008-05-17 18:14:43 +00007468- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7469 with RFC 3207 and forgets any knowledge obtained from the server not
7470 obtained from the TLS negotiation itself. Patch contributed by Bill
7471 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007472
Georg Brandl3ee81df2008-05-17 18:14:43 +00007473- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007474 that the SMTP.starttls() caller no longer needs to call ehlo()
7475 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007476 does not claim to support starttls. Adds the
7477 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7558 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7559 silently miscode subclasses of those types. Now, it raises a
7560 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007561

Georg Brandl3ee81df2008-05-17 18:14:43 +00007576 time so that opening a database previously created with the DB_DUP
7577 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7578 opens. Specifically: dictionary assignment to a DB object will
7579 replace all values for a given key when the database allows
7580 duplicate values. DB users should use DB.put(k, v) when they want
7581 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007582

7588 characters with ASCII value less than 32. Also, it correctly quotes
7589 dots only if they occur on a single line, as opposed to the previous
7590 behavior of quoting dots if they are the second character of any
7591 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007592

Georg Brandl3ee81df2008-05-17 18:14:43 +00007921- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7922 to ``PyTuple_SetItem``, it can be used to populate a brand new
7923 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00007925- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007927- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7928 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7929 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007930
7931- Patch #1720595: add T_BOOL to the range of structmember types.
7932
7933- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7934 ``PyFloat_GetInfo()`` to the float API.
7935
Georg Brandl3ee81df2008-05-17 18:14:43 +00007936- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7937 of w# format code incorrectly truncated the length to an int, even
7938 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7939 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007940
Georg Brandl3ee81df2008-05-17 18:14:43 +00007941- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7942 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007944- PEP 3123: Provide forward compatibility with Python 3.0, while
7945 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7946 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007947
Georg Brandl3ee81df2008-05-17 18:14:43 +00007948- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7949 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007950
7951- Patch #1733960: Allow T_LONGLONG to accept ints.
7952
7953- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7954
Christian Heimes000a0742008-01-03 22:16:32 +00007955- Added a new API function ``PyImport_ImportModuleNoBlock``.
7956
Georg Brandl6caad7d2008-01-26 14:19:22 +00007957- Bug #1637022: Prefix AST symbols with _Py_.
7958
7959- Fix some leftovers from the conversion from int to Py_ssize_t
7960 (relevant to strings and sequences of more than 2**31 items).
7961
7962- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7963 outside of pystate.c and should not be necessary.
7964
Georg Brandl3ee81df2008-05-17 18:14:43 +00007965- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7966 absolute imports. In earlier versions they might have used relative
7967 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007968
Georg Brandl3ee81df2008-05-17 18:14:43 +00007969- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7970 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007971
Georg Brandl3ee81df2008-05-17 18:14:43 +00007972- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7973 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007979- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7980 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7981 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7982 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007983
Georg Brandl3ee81df2008-05-17 18:14:43 +00007984- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
7985 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00007995- buildtools now raises a DeprecationWarning.
7996
Georg Brandl3ee81df2008-05-17 18:14:43 +00007997- Removed the macfs module. It had been deprecated since Python 2.5.
7998 This lead to the deprecation of macostools.touched() as it relied
7999 solely on macfs and was a no-op under OS X.
