Mark Dickinsondbbed042011-09-19 16:38:08 +010066- Issue #12973: Fix overflow checks that invoked undefined behaviour in
67 int.__pow__. These overflow checks were causing int.__pow__ to produce
68 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010069 compiler optimizing the check away. Also fix similar overflow checks
70 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
71 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010072

80 non-exception class.

Antoine Pitrou16166452011-07-12 22:04:20 +020082- Issue #12149: Update the method cache after a type's dictionnary gets
83 cleared by the garbage collector. This fixes a segfault when an instance
84 and its type get caught in a reference cycle, and the instance's
85 deallocator calls one of the methods on the type (e.g. when subclassing
86 IOBase). Diagnosis and patch by Davide Rizzo.
87
Florent Xiclunaa1f948b2012-01-24 21:05:10 +010088- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +020095 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
96 raw_input() interrupted by CTRL+c.
97
Łukasz Langa7a153902011-10-18 17:16:00 +020098- Issue #10860: httplib now correctly handles an empty port after port
99 delimiter in URLs.
100
Barry Warsawc5643282011-07-19 17:06:30 -0400101- dict_proxy objects now display their contents rather than just the class
102 name.

Florent Xiclunac2279652012-02-12 14:49:03 +0100155- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100156 has left two versions of customize_compiler, the original in
157 distutils.sysconfig and another copy in distutils.ccompiler, with some
158 parts of distutils calling one and others using the other.
159 Complete the revert back to only having one in distutils.sysconfig as
160 is the case in 3.x.
161
Ned Deily0d0ea482012-02-10 12:59:06 +0100162- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
163 Distutils-based packages with C extension modules may fail because
164 Apple has removed gcc-4.2, the version used to build python.org
165 64-bit/32-bit Pythons. If the user does not explicitly override
166 the default C compiler by setting the CC environment variable,
167 Distutils will now attempt to compile extension modules with clang
168 if gcc-4.2 is required but not found. Also as a convenience, if
169 the user does explicitly set CC, substitute its value as the default
170 compiler in the Distutils LDSHARED configuration variable for OS X.
171 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
172 SDK, neither of which are available in Xcode 4. This change does not
173 attempt to override settings to support their use with Xcode 4.)

Senthil Kumaran607e31e2012-02-09 17:43:31 +0800177- Issue #6005: Examples in the socket library documentation use sendall, where
178 relevant, instead send method.
179
Petri Lehtinenc7fd5232011-05-09 12:24:09 +0200180- Issue #10811: Fix recursive usage of cursors. Instead of crashing,
181 raise a ProgrammingError now.
182

Ned Deily87e82bb2011-06-28 19:52:59 -0700446- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
447 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
448 interpreter process. This could cause failures in non-Distutils subprocesses
449 and was unreliable since tests or user programs could modify the interpreter
450 environment after Distutils set it. Instead, have Distutils set the the
451 deployment target only in the environment of each build subprocess. It is
452 still possible to globally override the default by setting
453 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
454 greater or equal to the default value, the value with which the interpreter
455 was built.

Barry Warsawc5643282011-07-19 17:06:30 -0400483- sys.setcheckinterval() now updates the current ticker count as well as
484 updating the check interval, so if the user decreases the check interval,
485 the ticker doesn't have to wind down to zero from the old starting point
486 before the new interval takes effect. And if the user increases the
487 interval, it makes sure the new limit takes effect right away rather have an
488 early task switch before recognizing the new interval.

1433 This prevents user-created self-referencing ordered dictionaries from
1434 becoming permanently uncollectable GC garbage. The downside is that

1895
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001896- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1897 start byte and the continuation byte(s) are now considered invalid, instead
1898 of the number of bytes specified by the start byte.
1899 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1900 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1901 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001910- Issue #8748: Fix two issues with comparisons between complex and integer
1911 objects. (1) The comparison could incorrectly return True in some cases
1912 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1913 (2) The comparison raised an OverflowError for large integers, leading
1914 to unpredictable exceptions when combining integers and complex objects
1915 in sets or dicts.
1916
Mark Dickinson81336372010-05-30 12:12:25 +00001917- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00002054- Issue #1533: Fix inconsistency in range function argument processing: any
2055 non-float non-integer argument is now converted to an integer (if possible)
2056 using its __int__ method. Previously, only small arguments were treated this
2057 way; larger arguments (those whose __int__ was outside the range of a C long)
2058 would produce a TypeError.
Mark Dickinsona8d26682010-05-04 16:18:25 +00002059
Georg Brandlfee0f442010-05-22 21:26:21 +00002060- Issue #8202: ``sys.argv[0]`` is now set to '-m' instead of '-c' when searching

Georg Brandlfee0f442010-05-22 21:26:21 +00002066 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00002067 benefit compared to the dynamic memory allocation fallback. Patch by
2068 Charles-François Natali.

2078 on MacOS X. That is, ``python setup.py install --user`` will install into
2079 ``~/Library/Python/2.7`` instead of ``~/.local``.

Georg Brandlfee0f442010-05-22 21:26:21 +00002092- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
2093 messages when accessing undefined class attributes because of the cheap
2094 inheritance with the underlying socket object. The cheap inheritance has been
2095 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00002096
Georg Brandlfee0f442010-05-22 21:26:21 +00002097- Issue #4265: ``shutil.copyfile()`` was leaking file descriptors when disk

Georg Brandlfee0f442010-05-22 21:26:21 +00002108- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2109 operation raises multiple signals and more than one of those signals is
2110 trapped, the specification determines the order in which the signals should be
2111 handled. In many cases this order wasn't being followed, leading to the wrong
2112 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00002113
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +00002114- Issue #7865: The close() method of :mod:`io` objects should not swallow

2177 keywords.
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +00002178

2279Core and Builtins
2280-----------------
2281
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002282- Issue #7301: Add environment variable $PYTHONWARNINGS.
2283
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002284- Issue #8329: Don't return the same lists from select.select when no fds are
2285 changed.
2286
Georg Brandlfee0f442010-05-22 21:26:21 +00002287- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002288 on 64-bit machines. The shift count for either left or right shift is
2289 permitted to be up to sys.maxsize.
2290
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002291- Ensure that tokenization of identifiers is not affected by locale.
2292
Georg Brandlfee0f442010-05-22 21:26:21 +00002293- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002294
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002295- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2296
Georg Brandlfee0f442010-05-22 21:26:21 +00002297- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2298 with a non-empty format string. This is an effort to future-proof user
2299 code. If a derived class does not currently implement __format__ but later
2300 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002301 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002302 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002303
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002304- Issue #8268: Old-style classes (not just instances) now support weak
2305 references.
2306
Georg Brandlfee0f442010-05-22 21:26:21 +00002307- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2308 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00002309
Victor Stinnerc7790ed2010-03-22 12:36:28 +00002310- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00002311
Benjamin Peterson96545892010-03-21 20:21:00 +00002312- Issue #6474: Make error message from passing an inadequate number of keyword
2313 arguments to a function correct.
2314
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002315- Issue #8164: Don't allow lambda functions to have a docstring.
2316
Victor Stinner66644262010-03-10 22:30:19 +00002317- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002318 (SIGINT). If an error occurs while importing the site module, the error is
2319 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002320 module.
2321
Collin Winter001a3952010-03-18 21:54:01 +00002322- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00002327- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
2328
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002329- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002330 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2331 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002332
Benjamin Peterson76a23c12010-04-04 23:23:22 +00002333- Issue #8310: Allow dis to examine new style classes.
2334
Georg Brandlfee0f442010-05-22 21:26:21 +00002335- Issue #8257: The Decimal construct now accepts a float instance directly,
2336 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002337
2338 >>> Decimal(1.1)
2339 Decimal('1.100000000000000088817841970012523233890533447265625')
2340
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002341- collections.Counter() now supports a subtract() method.
2342
Georg Brandlfee0f442010-05-22 21:26:21 +00002343- The functools module now has a total_ordering() class decorator to simplify
2344 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002345
Georg Brandlfee0f442010-05-22 21:26:21 +00002346- The functools module also adds cmp_to_key() as a tool to transition old-style
2347 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002348
Georg Brandlfee0f442010-05-22 21:26:21 +00002349- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2350 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002351
Georg Brandlfee0f442010-05-22 21:26:21 +00002352- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2353 InvalidOperation instead of returning False. (Comparisons involving a quiet
2354 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2355 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002356
Georg Brandlfee0f442010-05-22 21:26:21 +00002357- Issue #2531: Comparison operations between floats and Decimal instances now
2358 return a result based on the numeric values of the operands; previously they
2359 returned an arbitrary result based on the relative ordering of id(float) and
2360 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002361
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002362- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002363 argument `-` which tells it to read files to compile from stdin. Each line is
2364 read on demand and the named file is compiled immediately. (Original patch by
2365 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002366
Georg Brandlfee0f442010-05-22 21:26:21 +00002367- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2368 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002370- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2371 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002372 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002373
Georg Brandlfee0f442010-05-22 21:26:21 +00002374- Comparisons using one of <, <=, >, >= between a complex instance and a
2375 Fractions instance now raise TypeError instead of returning True/False. This
2376 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2377 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002378
Michael Foorde6410c52010-03-29 20:04:23 +00002379- Addition of ``WeakSet`` to the ``weakref`` module.

2387
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002388- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002389 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2390 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002391
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002392- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2393 deprecated.
2394
Georg Brandlfee0f442010-05-22 21:26:21 +00002395- Issue #7860: platform.uname now reports the correct 'machine' type when Python
2396 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00002397

2402 existing at the same time, causing a Unicode error when configuration code
2403 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00002404
Georg Brandlfee0f442010-05-22 21:26:21 +00002405- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
2406 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00002407
Antoine Pitroueee91cd2010-03-26 19:27:16 +00002408- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
2409 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
2410 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00002411
Florent Xiclunacf82fa62010-03-21 12:27:20 +00002412- Issue #8179: Fix macpath.realpath() on a non-existing path.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002432- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002433 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2434 log file to compute the next rollover time. If the log file does not exist,
2435 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002436
Georg Brandlba83f822010-03-14 09:50:54 +00002437- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

2444
Georg Brandlba83f822010-03-14 09:50:54 +00002445- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2446 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2447 This is a behavior change, so email's minor version number is now bumped, to
2448 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00002449

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002476- Issue #8300: When passing a non-integer argument to struct.pack with any
2477 integer format code, struct.pack first attempts to convert the non-integer
2478 using its __index__ method. If that method is non-existent or raises
2479 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00002481- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2482 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2483 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002484 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2485 inconsistent: __int__ was used for some integer codes but not for others, and
2486 the set of integer codes for which it was used differed between native packing
2487 and standard packing.)

2892-----------------
2893
Georg Brandlba83f822010-03-14 09:50:54 +00002894- The ``__complex__()`` method is now looked up on the class of instances to
2895 make it consistent with other special methods.

2899
Mark Dickinson1b34d252010-01-01 17:27:30 +00002900- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002901 DeprecationWarning when passed a float argument where an integer was expected.
2902 These functions and methods now raise TypeError instead. The majority of the
2903 effects of this change are in the extension modules, but some core functions
2904 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2905 and many unicode/str methods.

2919 of integers: the result of a/b is now correctly rounded for ints a and b (at
2920 least on IEEE 754 platforms), and in particular does not depend on the
2921 internal representation of a long.

2929
Georg Brandlba83f822010-03-14 09:50:54 +00002930 These executables now work properly with the arch(1) command: ``arch -ppc

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003087
Georg Brandlba83f822010-03-14 09:50:54 +00003088- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3089 decimal string that's guaranteed to round back to x under correct rounding
3090 (with round-half-to-even rounding mode). Previously it gave a string based on
3091 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3092 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3093 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003094
Georg Brandlba83f822010-03-14 09:50:54 +00003095- Issue #7117: On almost all platforms: float-to-string and string-to-float
3096 conversions within Python are now correctly rounded. Places these conversions
3097 occur include: str for floats and complex numbers; the float and complex
3098 constructors; old-style and new-style numeric formatting; serialization and
3099 deserialization of floats and complex numbers using marshal, pickle and json;
3100 parsing of float and imaginary literals in Python code; Decimal-to-float
3101 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003102
Georg Brandlba83f822010-03-14 09:50:54 +00003103 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3104 providing correctly-rounded strtod and dtoa C functions. This code is
3105 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3106 the C compiler. There may be a small number of platforms on which correct
3107 operation of this code cannot be guaranteed, so the code is not used: notably,
3108 this applies to platforms where the C double format is not IEEE 754 binary64,
3109 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3110 and Python's configure script is unable to determine how to change the FPU
3111 precision. On these platforms conversions use the platform strtod and dtoa,
3112 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003114- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3115 uses the correctly-rounded string <-> float conversions described above (when
3116 available), and so produces correctly rounded results that will display nicely
3117 under the float repr. There are two related small changes: (1) round now
3118 accepts any class with an ``__index__()`` method for its second argument (but
3119 no longer accepts floats for the second argument), and (2) an excessively
3120 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3121 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003215- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
3216 build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
3217 of stdint.h on that platform.
Mark Dickinson2f865b92009-06-30 15:32:30 +00003218

Georg Brandlba83f822010-03-14 09:50:54 +00003251- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
3252 consistent with float("1e500") and interpretation of real and imaginary
3253 literals.
Mark Dickinsona4e0efa2009-05-20 18:43:07 +00003254

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003262- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00003263
Georg Brandlba83f822010-03-14 09:50:54 +00003264 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3265 (2) parsing of strings representing infinities and nans was locale aware; and
3266 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00003267
Georg Brandlba83f822010-03-14 09:50:54 +00003268- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3269 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3270 but with at least one decimal point and with a default precision
3271 of 12. Previously, the behavior the same but with a default precision of 6.
3272 This more closely matches ``str()``, and reduces surprises when adding
3273 alignment flags to the empty presentation type. This also affects the new
3274 complex.__format__ in the same way.
3275
3276- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3277 classtype's, even if it was None. property now inserts the __doc__ into the
3278 subclass instance __dict__.

3299
Georg Brandlba83f822010-03-14 09:50:54 +00003300- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves
3301 nans, infs or negative zeros.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00003338- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00003339 untrackable objects are not tracked by the garbage collector. This can reduce
3340 the size of collections and therefore the garbage collection overhead on
3341 long-running programs, depending on their particular use of datatypes.

3348 internal representation of integers, for performance reasons. Base 2**30 is
3349 enabled by default on 64-bit machines. Add --enable-big-digits option to
3350 configure, which overrides the default. Add sys.long_info structseq to
3351 provide information about the internal format.

3458 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3459 instances. On a typical machine this saves 3 bytes of memory (on average) per

3471
Georg Brandlba83f822010-03-14 09:50:54 +00003472- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3473 file objects with closefd=False. The file descriptor is still kept open but
3474 the file object behaves like a closed file. The ``FileIO`` object also got a
3475 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003495- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003498- On windows, ``os.chdir()`` given unicode was not working if
3499 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3500 this code path is really executed because I cannot move to such directory on
3501 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003503- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3504 element is temporarily replaced with an equivalent frozenset. But the
3505 eventual KeyError would always report the empty ``frozenset()`` as the missing
3506 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003526- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3527 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3528 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3529 of using the replace error handler in PyUnicode_DecodeUTF8().
3530
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003531- Issue #3739: The unicode-internal encoder now reports the number of characters

3533
Georg Brandlba83f822010-03-14 09:50:54 +00003534- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3535 allocator will be automatically disabled when running under Valgrind. This
3536 gives improved memory leak detection when running under Valgrind, while taking
3537 advantage of pymalloc at other times.

4704 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4705 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004902- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4903
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004904- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4905 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4906 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4907 ``printf`` function, whereas PyString_FromFormat has an independent
4908 implementation and uses "%zd" on all platforms for size_t values.
4909 This makes a difference on win64, where ``printf`` needs "%Id" to display
4910 64bit values.

4916 object; previously an int would be returned for small values. the __long__
4917 method is allowed to return either an int or a long, but the behaviour of
4918 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004927 was correctly parsed but parsing of subsequent arguments failed.
4928
Vinay Sajip35e3b032008-09-01 14:33:59 +00004929- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004930 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4931 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4932 when given a tuple of classes as second argument, were looking up
4933 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4934 type object.

5079-----------------
5080
Guido van Rossumf8402962008-08-20 15:01:50 +00005081- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5082 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5083 extensions do not automatically benefit from the class attribute
5084 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5085 to their tp_flags field if they care. This is a backwards
5086 compatibility feature; in 3.0, all types will use the cache by
5087 default.
5088
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005089- Keyword arguments can now follow starred arguments. (``f(a, *args,
5090 keyword=23)`` is now valid syntax.)
5091
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005092- ctypes function pointers that are COM methods have a boolean True
5093 value again.

5103 ValueError consistently across platforms.
5104
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005105- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5106 (64bit Unix, for example), unichr() would truncate its argument and return
5107 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00005109- Apply security patches from Apple.
5110
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005111- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5112 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5113
Antoine Pitrou92f82162008-07-25 22:22:08 +00005114- Issue #1819: function calls with several named parameters are now on
5115 average 35% faster (as measured by pybench).
5116
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005117- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5118 the python debugger steps into a class statement: the free variables (local
5119 variables defined in an outer scope) would be deleted from the outer scope.
5120
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005121- Issue #2620: Overflow checking when allocating or reallocating memory
5122 was not always being done properly in some python types and extension
5123 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5124 all been updated to perform better checks and places in the code that
5125 would previously leak memory on the error path when such an allocation
5126 failed have been fixed.

5132
Benjamin Petersone977ad42008-08-20 01:42:01 +00005133- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5134 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5135
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005136- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5137 version reported by these tools does not necessarily follow the python
5138 version numbering scheme, so the module is less strict when parsing it.
5139
Nick Coghlanf70385a2008-08-18 12:42:46 +00005140- Issue #2235: Added Py3k warnings for types which will become unhashable
5141 under the stricter __hash__ inheritance rules in 3.0. Several types
5142 which did not meet the rules for hash invariants and were already
5143 unhashable in 3.0 have now been explicitly flagged as unhashable in
5144 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5145 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5146
Brett Cannon88f801d2008-08-18 00:46:22 +00005147- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5148 imported into the module but exposed as part of the module's API.
5149

5170
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005171- Issue #2676: in the email package, content-type parsing was hanging on
5172 pathological input because of quadratic or exponential behaviour of a
5173 regular expression.
5174

5176 thread-safe.
5177
Brett Cannonbf3157b2008-08-14 05:00:03 +00005178- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5179 since mimetools itself is deprecated. Because modules are cached, all
5180 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5181
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005182- Issue #3134: shutil referenced undefined WindowsError symbol.

5191 a MemoryError rather than silently stop the iteration.
5192
Guido van Rossum59ce9012008-08-09 14:55:34 +00005193- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5194 to _sre.compile() will now be rejected. This should not affect anybody
5195 since the re.compile() function never generates invalid re-bytecode.
5196
Skip Montanaroa032bf42008-08-08 22:52:51 +00005197- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5198 upon first access it can be automatically initialized from the csv file if
5199 it wasn't initialized during instantiation.
5200
Brett Cannon3aa2a492008-08-06 22:28:09 +00005201- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5202 the reload() built-in has been removed.
5203
Brett Cannon7e30b672008-08-04 21:52:25 +00005204- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005205 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5213 raised an AttributeError.
5214
Benjamin Peterson01a24322008-07-28 23:35:27 +00005215- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005216 asking for a specific length. This problem only affected files opened
5217 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005218

5243 file name rather than a ZipInfo instance, so files are extracted with
5244 mode 0600 rather than 000 under Unix.
5245
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005246- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5247 argument in python 2.5, this broke code that subclassed Popen to include its
5248 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5257
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005258- Issue #2235: the C API function PyObject_HashNotImplemented and its
5259 interaction with the tp_hash slot (added in 2.6b2) are now documented
5260
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005261- Issue #643841: The language reference now provides more detailed
5262 coverage of the lookup process for special methods. The disclaimers
5263 regarding lack of coverage of new-style classes have also been
5264 removed, since the coverage is now fairly reasonable.

5268================================
5269
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005270*Release date: 17-Jul-2008*
5271
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005272Core and Builtins
5273-----------------
5274
Georg Brandl3e483f62008-07-16 22:57:41 +00005275- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5276 its methods now allow for items objects that can be converted to
5277 an integer using operator.index().
5278
Mark Dickinson64b7e502008-07-16 09:40:03 +00005279- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5280 produced a ValueError instead of giving the correct float.
5281
Eric Smitha5fa5a22008-07-16 00:11:49 +00005282- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5283 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5284
Mark Dickinson7103aa42008-07-15 19:08:33 +00005285- Issue #3008: the float type has a new instance method 'float.hex'
5286 and a new class method 'float.fromhex' to convert floating-point
5287 numbers to and from hexadecimal strings, respectively.
5288
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005289- Issue #2235: __hash__ is once again inherited by default. To allow
5290 collections.Hashable to remain meaningful in the presence of the
5291 default hash implementation (object.__hash__), it is now possible
5292 to explicit block inheritance of hash by setting __hash__=None at
5293 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5294 level.
5295
Nick Coghlanb028f502008-07-13 14:52:36 +00005296- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5297 the parent module cannot be found while performing an absolute import.
5298 This means that an incorrectly defined __package__ attribute will
5299 now only prevent relative imports in that module rather than causing
5300 all imports from that module to fail.
5301
Nick Coghlan14ff9942008-07-08 14:21:42 +00005302- Issue #2517: Allow unicode messages in Exceptions again by correctly
5303 bypassing the instance dictionary when looking up __unicode__ on
5304 new-style classes.
5305
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005306- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5307 set to a custom object whose write() method happens to install
5308 another file in sys.stdout.
5309
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005310- Issue #3088: Corrected a race condition in classes derived from
5311 threading.local: the first member set by a thread could be saved in
5312 another thread's dictionary.
5313
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005314- Issue #3004: Minor change to slice.indices(): the start and stop
5315 arguments are now treated identically, making the behaviour easier
5316 to describe and understand. For example, slice(None, -10,
5317 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5318 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5319 10, -1).
5320
Georg Brandl278fc502008-07-19 12:46:12 +00005321- Issue #3219: Calling a function with repeated keyword arguments,
5322 f(a=2, a=23), would not cause a syntax error. This was a regression
5323 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005324
Georg Brandl278fc502008-07-19 12:46:12 +00005325- Issue #2862: Make int and float freelist management consistent with
5326 other freelists. Changes their CompactFreeList apis into
5327 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005328

5330-------
5331
Thomas Heller57adf222008-08-14 19:10:48 +00005332- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5333 api functions without holding the GIL, which could lead to a fatal
5334 error when they failed.
5335
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005336- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005344- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5345 ForkingPickler.register() to resolve conflict with ctypes.
5346
Vinay Sajip51e65192008-07-18 09:01:10 +00005347- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005348
Thomas Heller880f5292008-07-15 19:39:38 +00005349- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5350 a valid dlerror() message.
5351
Thomas Heller2bad6572008-07-15 17:19:50 +00005352- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5353 incomplete structure was created.
5354
Brett Cannon3d0b9f02008-07-13 01:15:07 +00005355- Issue #3339: dummy_thread.acquire() should not return None.
5356
Raymond Hettingerb01713e2008-07-10 14:34:57 +00005357- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
5358
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005359- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005360
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005361- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5362 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005363 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005364 content-length. The problem had been corrected in the 2.4 branch, but never
5365 merged into trunk.
5366
Georg Brandle78fbcc2008-07-05 10:13:36 +00005367- Issue #2663: add filtering capability to shutil.copytree().

5373- Issue #1746: Correct handling of zipfile archive comments (previously
5374 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00005375 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00005376
Vinay Sajip51e65192008-07-18 09:01:10 +00005377- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005378 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005379
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005380- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5381 handling is now the same as that of other special attributes like __name__).
5382
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005383- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5384 removal in Python 3.0 in favor of urllib2.urlopen().
5385

Georg Brandl5cc774e2008-06-11 20:28:06 +00005773 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005774
5775 This is controlled by the configure argument ``--with-universal-archs``:
5776
5777 - ``--with-universal-archs=all``: install 4-way universal
5778
5779 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5780
5781 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5782
5783 This option should be used in combination with ``--enable-universalsdk=``.
5784
5785 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 +00005835- Issue #1631171: Re-implement the 'warnings' module in C (the
5836 original Python code has been kept as backup). This will allow for
5837 using the 'warning's machinery in such places as the parser where
5838 use of pure Python code is not possible. Both the ``showarning()``
5839 and ``formatwarning()`` gain an optional 'line' argument which is
5840 not called by default for backwards-compatibility reasons. Setting
5841 ``warnings.showwarning()`` to an implementation that lacks support
5842 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005905- Issue #2550: The approach used by client/server code for obtaining
5906 ports to listen on in network-oriented tests has been refined in an
5907 effort to facilitate running multiple instances of the entire
5908 regression test suite in parallel without issue.
5909 test_support.bind_port() has been fixed such that it will always
5910 return a unique port -- which wasn't always the case with the
5911 previous implementation, especially if socket options had been set
5912 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5913 new implementation of bind_port() will actually raise an exception
5914 if it is passed an AF_INET/SOCK_STREAM socket with either the
5915 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5916 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5917 the socket it's been passed. This currently only applies to
5918 Windows. This option prevents any other sockets from binding to the
5919 host/port we've bound to, thus removing the possibility of the
5920 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5921 when a second SOCK_STREAM socket binds and accepts to a host/port
5922 that's already been bound by another socket. The optional preferred
5923 port parameter to bind_port() has been removed. Under no
5924 circumstances should tests be hard coding ports!
5925
5926 test_support.find_unused_port() has also been introduced, which will
5927 pass a temporary socket object to bind_port() in order to obtain an
5928 unused port. The temporary socket object is then closed and
5929 deleted, and the port is returned. This method should only be used
5930 for obtaining an unused port in order to pass to an external program
5931 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5932 a parameter to a server-oriented class that doesn't give you direct
5933 access to the underlying socket used.
5934
5935 Finally, test_support.HOST has been introduced, which should be used
5936 for the host argument of any relevant socket calls (i.e. bind and
5937 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005938
5939 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005940 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005941 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5942 test_asynchat and test_socket_ssl.
5943
Georg Brandl3ee81df2008-05-17 18:14:43 +00005944 It is now possible for multiple instances of the regression test
5945 suite to run in parallel without issue.

6211Core and builtins
6212-----------------
6213
Fred Drakea8ee94b2008-03-01 02:45:07 +00006214- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006215 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006216
Georg Brandlad61bc82008-02-23 15:11:18 +00006217- Issue #2067: file.__exit__() now calls subclasses' close() method.
6218
6219- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006220
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006221- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006222 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006223
Eric Smitha73fbe72008-02-23 03:09:44 +00006224- Added the future_builtins module, which contains hex() and oct().
6225 These are the PEP 3127 version of these functions, designed to be
6226 compatible with the hex() and oct() builtins from Python 3.0. They
6227 differ slightly in their output formats from the existing, unchanged
6228 Python 2.6 builtins. The expected usage of the future_builtins
6229 module is:
6230 from future_builtins import hex, oct
6231
Eric Smith7ef40bf2008-02-20 23:34:22 +00006232- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6233 exponents for exponents with absolute value < 100. Follows C99
6234 standard. This is a change on Windows, which would use 3 digits.
6235 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6236 so that any alterations it does to the resulting string will be
6237 available in stringlib/formatter.h (for float.__format__).
6238
Eric Smith5a3c1352008-02-19 13:21:56 +00006239- Implemented PEP 3101, Advanced String Formatting. This adds a new
6240 builtin format(); a format() method for str and unicode; a
6241 __format__() method to object, str, unicode, int, long, float, and
6242 datetime; the class string.Formatter; and the C API
6243 PyObject_Format().
6244
Georg Brandl3ee81df2008-05-17 18:14:43 +00006245- Fixed several potential crashes, all caused by specially crafted
6246 __del__ methods exploiting objects in temporarily inconsistent
6247 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006248
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006249- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006250 prevent a possible crash: an Abstract Base Class would try to access
6251 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006252
Georg Brandl3ee81df2008-05-17 18:14:43 +00006253- Fixed repr() and str() of complex numbers with infinity or nan as
6254 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006255
Georg Brandl3ee81df2008-05-17 18:14:43 +00006256- Clear all free lists during a gc.collect() of the highest generation
6257 in order to allow pymalloc to free more arenas. Python may give back
6258 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006259
Georg Brandl3ee81df2008-05-17 18:14:43 +00006260- Issue #2045: Fix an infinite recursion triggered when printing a
6261 subclass of collections.defaultdict, if its default_factory is set
6262 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006263
Christian Heimesf75dbef2008-02-08 00:11:31 +00006264- Fixed a minor memory leak in dictobject.c. The content of the free
6265 list was not freed on interpreter shutdown.
6266
Georg Brandl21e99f42010-03-07 15:23:59 +00006267- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006268 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006269
Georg Brandl3ee81df2008-05-17 18:14:43 +00006270- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6271 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006272 to compact the internal free lists of pre-allocted ints and floats.
6273
Georg Brandl3ee81df2008-05-17 18:14:43 +00006274- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6275 calls. Python expected the return type int but the fork familie
6276 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006277
Georg Brandl3ee81df2008-05-17 18:14:43 +00006278- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6279 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006280
Georg Brandl3ee81df2008-05-17 18:14:43 +00006281- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6282 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006283
Georg Brandl3ee81df2008-05-17 18:14:43 +00006284- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6285 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006286
Georg Brandl3ee81df2008-05-17 18:14:43 +00006287- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6288 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006289
Georg Brandl3ee81df2008-05-17 18:14:43 +00006290- Patch #1473257: generator objects gain a gi_code attribute. This is
6291 the same object as the func_code attribute of the function that
6292 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006293
Georg Brandl3ee81df2008-05-17 18:14:43 +00006294- Issue #1920: "while 0" statements were completely removed by the
6295 compiler, even in the presence of an "else" clause, which is
6296 supposed to be run when the condition is false. Now the compiler
6297 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006298
Guido van Rossumeead05f2008-01-24 18:21:02 +00006299- A few crashers fixed: weakref_in_del.py (issue #1377858);
6300 loosing_dict_ref.py (issue #1303614, test67.py);
6301 borrowed_ref_[34].py (not in tracker).
6302
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006303- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006304 suppressed while an extension is loaded by calling SetErrorMode in
6305 dynload_win.c. The error is still reported properly.
6306
Georg Brandl3ee81df2008-05-17 18:14:43 +00006307- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006308 several extension methods and modules do not work without unicode
6309 support.
6310
Georg Brandl26543b12008-01-21 18:36:51 +00006311- Issue #1882: when compiling code from a string, encoding cookies in the
6312 second line of code were not always recognized correctly.
6313
Georg Brandl14404b62008-01-19 19:27:05 +00006314- Issue #1679: "0x" was taken as a valid integer literal.
6315
Georg Brandl6caad7d2008-01-26 14:19:22 +00006316- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006317 added.
6318
Christian Heimesc94e2b52008-01-14 04:13:37 +00006319- sys.float_info / PyFloat_GetInfo: The floating point information
6320 object was converted from a dict to a specialized structseq object.
6321
Georg Brandl3ee81df2008-05-17 18:14:43 +00006322- Patch #1816: Added sys.flags structseq. It exposes the status of
6323 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006324
Georg Brandl3ee81df2008-05-17 18:14:43 +00006325- Objects/structseq.c: Implemented new structseq representation. The
6326 patch makes structseqs (e.g. the return value of os.stat) more
6327 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006328
Georg Brandl3ee81df2008-05-17 18:14:43 +00006329- Patch #1700288: added a type attribute cache that caches method
6330 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006331
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006332- Bug #1776: __import__() no longer accepts filenames on any platform.
6333 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006334
Georg Brandlaed6c662008-01-07 17:25:53 +00006335- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6336
Georg Brandl3ee81df2008-05-17 18:14:43 +00006337- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6338 envvar and sys.dont_write_bytecode attribute. All these can be set
6339 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006340
Georg Brandl3ee81df2008-05-17 18:14:43 +00006341- Improve some exception messages when Windows fails to load an
6342 extension module. Now we get for example '%1 is not a valid Win32
6343 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006344
Georg Brandl3ee81df2008-05-17 18:14:43 +00006345- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006347- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6348 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006349
Christian Heimes0a8143f2007-12-18 23:22:54 +00006350- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006351 and INF. float("nan"), float("inf") and float("-inf") now work on
6352 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006353
Georg Brandl3ee81df2008-05-17 18:14:43 +00006354- Compiler now generates simpler and faster code for dictionary
6355 literals. The oparg for BUILD_MAP now indicates an estimated
6356 dictionary size. There is a new opcode, STORE_MAP, for adding
6357 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006358
Georg Brandl3ee81df2008-05-17 18:14:43 +00006359- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006361- Issue #1620: New property decorator syntax was modifying the
6362 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006363
Georg Brandl3ee81df2008-05-17 18:14:43 +00006364- Issue #1538: Avoid copying string in split/rsplit if the split char
6365 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006366
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006367- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006368 SystemError.
6369
Nick Coghlanef01d822007-12-03 12:55:17 +00006370- PEP 366: Allow explicit relative imports when executing modules
6371 inside packages with the -m switch via a new module level
6372 __package__ attribute.
6373
Georg Brandl3ee81df2008-05-17 18:14:43 +00006374- Issue #1402: Fix a crash on exit, when another thread is still
6375 running, and if the deallocation of its frames somehow calls the
6376 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006377

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006381 attribute of an empty cell object.
6382
Georg Brandl3ee81df2008-05-17 18:14:43 +00006383- Issue #1460: The utf-7 incremental decoder did not accept truncated
6384 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006385
Georg Brandl3ee81df2008-05-17 18:14:43 +00006386- Patch #1739468: Directories and zipfiles containing a __main__.py
6387 file can now be directly executed by passing their name to the
6388 interpreter. The directory/zipfile is automatically inserted as the
6389 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006390
Georg Brandl3ee81df2008-05-17 18:14:43 +00006391- Issue #1265: Fix a problem with sys.settrace, if the tracing
6392 function uses a generator expression when at the same time the
6393 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006394
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006395- sets and frozensets now have an isdisjoint() method.
6396
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006397- optimize the performance of builtin.sum().
6398
Neal Norwitz44f326e2007-10-05 05:29:17 +00006399- Fix warnings found by the new version of the Coverity checker.
6400
Georg Brandl21e99f42010-03-07 15:23:59 +00006401- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006402 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6403 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006404
Georg Brandl3ee81df2008-05-17 18:14:43 +00006405- Issue #1686386: Tuple's tp_repr did not take into account the
6406 possibility of having a self-referential tuple, which is possible
6407 from C code. Nor did object's tp_str consider that a type's tp_str
6408 could do something that could lead to an inifinite recursion.
6409 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6410 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006411
Georg Brandl3ee81df2008-05-17 18:14:43 +00006412- Issue #1164: It was possible to trigger deadlock when using the
6413 'print' statement to write to a file since the GIL was not released
6414 as needed. Now PyObject_Print() does the right thing along with
6415 various tp_print implementations of the built-in types and those in
6416 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006417
Georg Brandl3ee81df2008-05-17 18:14:43 +00006418- Issue #1147: Exceptions were directly allowing string exceptions in
6419 their throw() method even though string exceptions no longer
6420 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006421
Georg Brandl3ee81df2008-05-17 18:14:43 +00006422- Issue #1096: Prevent a segfault from getting the repr of a very
6423 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00006425- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006426 PyObject_Call() never calling back out to Python code to trigger
6427 recursion depth updates/checks. Required the creation of a static
6428 RuntimeError instance in case normalizing an exception put the
6429 recursion check value past its limit. Fixes crashers
6430 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006431
Georg Brandl3ee81df2008-05-17 18:14:43 +00006432- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006445- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006446 __*__ attributes. (Some already existed, e.g., __doc__ and
6447 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006448
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006449- Add -3 option to the interpreter to warn about features that are
6450 deprecated and will be changed/removed in Python 3.0.
6451

6453 calls.
6454
Collin Winter62903052007-05-18 23:11:24 +00006455- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006456 "except E as target:". This is to provide forwards compatibility
6457 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006458
Brett Cannon229cee22007-05-05 01:34:02 +00006459- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006464- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006465 setting a plain string, ie don't expand to single letter identifiers.
6466
Raymond Hettinger13936692007-04-11 18:40:58 +00006467- Request #1191699: Slices can now be pickled.

6477
Guido van Rossum143b5642007-03-23 04:58:42 +00006478- Bug #1683368: The object.__init__() and object.__new__() methods are
6479 now stricter in rejecting excess arguments. The only time when
6480 either allows excess arguments is when it is not overridden and the
6481 other one is. For backwards compatibility, when both are
6482 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006483 warning later). Also, type.__init__() insists on the same signature
6484 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006485
Georg Brandl3ee81df2008-05-17 18:14:43 +00006486- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6487 object to complex using its __complex__() method before falling back
6488 to the __float__() method. Therefore, the functions in the cmath
6489 module now can operate on objects that define a __complex__()
6490 method.

6507
Georg Brandl7b9c5552007-03-12 14:30:05 +00006508- Bug #1678647: write a newline after printing an exception in any
6509 case, even when converting the value to a string failed.
6510
Georg Brandl871f1bc2007-03-12 13:17:36 +00006511- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006512 its argument, if it exists. If not, it will work like before. This
6513 allows customizing the output of dir() in the presence of a
6514 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006515
Collin Winter276887b2007-03-12 16:11:39 +00006516- Patch #922167: Python no longer segfaults when faced with infinitely
6517 self-recursive reload() calls (as reported by bug #742342).

6523 parthensized forms. This means complex(repr(x)) now works instead of
6524 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006525
Georg Brandlaa2321b2007-03-07 00:40:28 +00006526- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006527 makes the filenames the warning module prints much more sensible
6528 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006529

Georg Brandl0fca97a2007-03-05 22:28:08 +00006541- Patch #1674228: when assigning a slice (old-style), check for the
6542 sq_ass_slice instead of the sq_slice slot.
6543
Georg Brandl3ee81df2008-05-17 18:14:43 +00006544- When printing an unraisable error, don't print exceptions. before
6545 the name. This duplicates the behavior whening normally printing
6546 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007079 AttributeError instead of an IOError when the server's response
7080 didn't contain a valid HTTP status line.

7171 TestCase and TestSuite subclasses (not instances) are no longer
7172 accepted in TestSuite.addTest(). This should cause no

7174 -- the failure just occurred later, with a more cumbersome

Georg Brandl3ee81df2008-05-17 18:14:43 +00007456- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7457 with RFC 3207 and forgets any knowledge obtained from the server not
7458 obtained from the TLS negotiation itself. Patch contributed by Bill
7459 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007460
Georg Brandl3ee81df2008-05-17 18:14:43 +00007461- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007462 that the SMTP.starttls() caller no longer needs to call ehlo()
7463 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007464 does not claim to support starttls. Adds the
7465 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7546 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7547 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007564 time so that opening a database previously created with the DB_DUP
7565 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7566 opens. Specifically: dictionary assignment to a DB object will
7567 replace all values for a given key when the database allows
7568 duplicate values. DB users should use DB.put(k, v) when they want
7569 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007570

7576 characters with ASCII value less than 32. Also, it correctly quotes
7577 dots only if they occur on a single line, as opposed to the previous
7578 behavior of quoting dots if they are the second character of any
7579 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007580

Georg Brandl3ee81df2008-05-17 18:14:43 +00007909- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7910 to ``PyTuple_SetItem``, it can be used to populate a brand new
7911 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007912
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007913- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007915- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7916 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7917 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007918
7919- Patch #1720595: add T_BOOL to the range of structmember types.
7920
7921- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7922 ``PyFloat_GetInfo()`` to the float API.
7923
Georg Brandl3ee81df2008-05-17 18:14:43 +00007924- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7925 of w# format code incorrectly truncated the length to an int, even
7926 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7927 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007928
Georg Brandl3ee81df2008-05-17 18:14:43 +00007929- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7930 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007931
Georg Brandl3ee81df2008-05-17 18:14:43 +00007932- PEP 3123: Provide forward compatibility with Python 3.0, while
7933 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7934 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007935
Georg Brandl3ee81df2008-05-17 18:14:43 +00007936- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7937 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007938
7939- Patch #1733960: Allow T_LONGLONG to accept ints.
7940
7941- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7942
Christian Heimes000a0742008-01-03 22:16:32 +00007943- Added a new API function ``PyImport_ImportModuleNoBlock``.
7944
Georg Brandl6caad7d2008-01-26 14:19:22 +00007945- Bug #1637022: Prefix AST symbols with _Py_.
7946
7947- Fix some leftovers from the conversion from int to Py_ssize_t
7948 (relevant to strings and sequences of more than 2**31 items).
7949
7950- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7951 outside of pystate.c and should not be necessary.
7952
Georg Brandl3ee81df2008-05-17 18:14:43 +00007953- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7954 absolute imports. In earlier versions they might have used relative
7955 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007956
Georg Brandl3ee81df2008-05-17 18:14:43 +00007957- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7958 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007959
Georg Brandl3ee81df2008-05-17 18:14:43 +00007960- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7961 macro so it can be used as an expression.

7966
Georg Brandl3ee81df2008-05-17 18:14:43 +00007967- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7968 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7969 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7970 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007971
Georg Brandl3ee81df2008-05-17 18:14:43 +00007972- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00007983- buildtools now raises a DeprecationWarning.
7984
Georg Brandl3ee81df2008-05-17 18:14:43 +00007985- Removed the macfs module. It had been deprecated since Python 2.5.
7986 This lead to the deprecation of macostools.touched() as it relied
7987 solely on macfs and was a no-op under OS X.
