Mark Dickinsondbbed042011-09-19 16:38:08 +010075- Issue #12973: Fix overflow checks that invoked undefined behaviour in
76 int.__pow__. These overflow checks were causing int.__pow__ to produce
77 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010078 compiler optimizing the check away. Also fix similar overflow checks
79 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Antoine Pitrou16166452011-07-12 22:04:20 +020091- Issue #12149: Update the method cache after a type's dictionnary gets
92 cleared by the garbage collector. This fixes a segfault when an instance
93 and its type get caught in a reference cycle, and the instance's
94 deallocator calls one of the methods on the type (e.g. when subclassing
95 IOBase). Diagnosis and patch by Davide Rizzo.

105 raw_input() interrupted by CTRL+c.
106
Łukasz Langa7a153902011-10-18 17:16:00 +0200107- Issue #10860: httplib now correctly handles an empty port after port
108 delimiter in URLs.
109

Florent Xiclunac2279652012-02-12 14:49:03 +0100148- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100149 has left two versions of customize_compiler, the original in
150 distutils.sysconfig and another copy in distutils.ccompiler, with some
151 parts of distutils calling one and others using the other.

153 is the case in 3.x.
154
Ned Deily0d0ea482012-02-10 12:59:06 +0100155- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
156 Distutils-based packages with C extension modules may fail because
157 Apple has removed gcc-4.2, the version used to build python.org
158 64-bit/32-bit Pythons. If the user does not explicitly override
159 the default C compiler by setting the CC environment variable,
160 Distutils will now attempt to compile extension modules with clang
161 if gcc-4.2 is required but not found. Also as a convenience, if
162 the user does explicitly set CC, substitute its value as the default
163 compiler in the Distutils LDSHARED configuration variable for OS X.
164 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
165 SDK, neither of which are available in Xcode 4. This change does not
166 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700441- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
442 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
443 interpreter process. This could cause failures in non-Distutils subprocesses
444 and was unreliable since tests or user programs could modify the interpreter
445 environment after Distutils set it. Instead, have Distutils set the the
446 deployment target only in the environment of each build subprocess. It is
447 still possible to globally override the default by setting
448 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
449 greater or equal to the default value, the value with which the interpreter
450 was built.

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

Raymond Hettinger20397532010-09-12 02:11:45 +00001426- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1427 This prevents user-created self-referencing ordered dictionaries from
1428 becoming permanently uncollectable GC garbage. The downside is that
1429 removing __del__ means that the internal doubly-linked list has to wait for
1430 GC collection rather than freeing memory immediately when the refcnt drops
1431 to zero.

1436

1439 to fetch the original errno, or to filter timeout errors. Now the
1440 original error is re-raised.

1460 falling into recursion.
1461
R. David Murray7c4bf552010-08-25 01:45:57 +00001462- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four

1889
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001890- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1891 start byte and the continuation byte(s) are now considered invalid, instead
1892 of the number of bytes specified by the start byte.
1893 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1894 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1895 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001904- Issue #8748: Fix two issues with comparisons between complex and integer
1905 objects. (1) The comparison could incorrectly return True in some cases
1906 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1907 (2) The comparison raised an OverflowError for large integers, leading
1908 to unpredictable exceptions when combining integers and complex objects
1909 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001911- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00002048- Issue #1533: Fix inconsistency in range function argument processing: any
2049 non-float non-integer argument is now converted to an integer (if possible)
2050 using its __int__ method. Previously, only small arguments were treated this
2051 way; larger arguments (those whose __int__ was outside the range of a C long)
2052 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00002060 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00002061 benefit compared to the dynamic memory allocation fallback. Patch by

2087 messages when accessing undefined class attributes because of the cheap
2088 inheritance with the underlying socket object. The cheap inheritance has been
2089 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00002102- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2103 operation raises multiple signals and more than one of those signals is
2104 trapped, the specification determines the order in which the signals should be
2105 handled. In many cases this order wasn't being followed, leading to the wrong
2106 Python exception being raised.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002276- Issue #7301: Add environment variable $PYTHONWARNINGS.
2277
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002278- Issue #8329: Don't return the same lists from select.select when no fds are
2279 changed.
2280
Georg Brandlfee0f442010-05-22 21:26:21 +00002281- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002282 on 64-bit machines. The shift count for either left or right shift is
2283 permitted to be up to sys.maxsize.
2284
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002285- Ensure that tokenization of identifiers is not affected by locale.
2286
Georg Brandlfee0f442010-05-22 21:26:21 +00002287- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002288
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002289- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2290
Georg Brandlfee0f442010-05-22 21:26:21 +00002291- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2292 with a non-empty format string. This is an effort to future-proof user
2293 code. If a derived class does not currently implement __format__ but later
2294 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002295 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002296 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002297
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002298- Issue #8268: Old-style classes (not just instances) now support weak
2299 references.
2300
Georg Brandlfee0f442010-05-22 21:26:21 +00002301- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2302 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00002303

Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002309- Issue #8164: Don't allow lambda functions to have a docstring.
2310
Victor Stinner66644262010-03-10 22:30:19 +00002311- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002312 (SIGINT). If an error occurs while importing the site module, the error is
2313 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002314 module.

2322
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002323- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002324 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2325 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002327- Issue #8310: Allow dis to examine new style classes.
2328
Georg Brandlfee0f442010-05-22 21:26:21 +00002329- Issue #8257: The Decimal construct now accepts a float instance directly,
2330 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002331
2332 >>> Decimal(1.1)
2333 Decimal('1.100000000000000088817841970012523233890533447265625')
2334
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002335- collections.Counter() now supports a subtract() method.
2336
Georg Brandlfee0f442010-05-22 21:26:21 +00002337- The functools module now has a total_ordering() class decorator to simplify
2338 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002339
Georg Brandlfee0f442010-05-22 21:26:21 +00002340- The functools module also adds cmp_to_key() as a tool to transition old-style
2341 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002342
Georg Brandlfee0f442010-05-22 21:26:21 +00002343- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2344 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002345
Georg Brandlfee0f442010-05-22 21:26:21 +00002346- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2347 InvalidOperation instead of returning False. (Comparisons involving a quiet
2348 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2349 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002350
Georg Brandlfee0f442010-05-22 21:26:21 +00002351- Issue #2531: Comparison operations between floats and Decimal instances now
2352 return a result based on the numeric values of the operands; previously they
2353 returned an arbitrary result based on the relative ordering of id(float) and
2354 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002355
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002356- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002357 argument `-` which tells it to read files to compile from stdin. Each line is
2358 read on demand and the named file is compiled immediately. (Original patch by
2359 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002360
Georg Brandlfee0f442010-05-22 21:26:21 +00002361- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2362 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002364- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2365 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002366 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002367
Georg Brandlfee0f442010-05-22 21:26:21 +00002368- Comparisons using one of <, <=, >, >= between a complex instance and a
2369 Fractions instance now raise TypeError instead of returning True/False. This
2370 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2371 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002372

2381
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002382- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002383 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2384 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002385
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002386- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2387 deprecated.
2388
Georg Brandlfee0f442010-05-22 21:26:21 +00002389- Issue #7860: platform.uname now reports the correct 'machine' type when Python
2390 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00002391

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002426- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002427 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2428 log file to compute the next rollover time. If the log file does not exist,
2429 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002430

Georg Brandlba83f822010-03-14 09:50:54 +00002439- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2440 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2441 This is a behavior change, so email's minor version number is now bumped, to
2442 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002470- Issue #8300: When passing a non-integer argument to struct.pack with any
2471 integer format code, struct.pack first attempts to convert the non-integer
2472 using its __index__ method. If that method is non-existent or raises
2473 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00002475- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2476 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2477 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002478 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2479 inconsistent: __int__ was used for some integer codes but not for others, and
2480 the set of integer codes for which it was used differed between native packing
2481 and standard packing.)

2886-----------------
2887
Georg Brandlba83f822010-03-14 09:50:54 +00002888- The ``__complex__()`` method is now looked up on the class of instances to
2889 make it consistent with other special methods.

2893
Mark Dickinson1b34d252010-01-01 17:27:30 +00002894- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002895 DeprecationWarning when passed a float argument where an integer was expected.
2896 These functions and methods now raise TypeError instead. The majority of the
2897 effects of this change are in the extension modules, but some core functions
2898 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2899 and many unicode/str methods.

2914 least on IEEE 754 platforms), and in particular does not depend on the
2915 internal representation of a long.

2923
Georg Brandlba83f822010-03-14 09:50:54 +00002924 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00003082- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3083 decimal string that's guaranteed to round back to x under correct rounding
3084 (with round-half-to-even rounding mode). Previously it gave a string based on
3085 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3086 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3087 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003088
Georg Brandlba83f822010-03-14 09:50:54 +00003089- Issue #7117: On almost all platforms: float-to-string and string-to-float
3090 conversions within Python are now correctly rounded. Places these conversions
3091 occur include: str for floats and complex numbers; the float and complex
3092 constructors; old-style and new-style numeric formatting; serialization and
3093 deserialization of floats and complex numbers using marshal, pickle and json;
3094 parsing of float and imaginary literals in Python code; Decimal-to-float
3095 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003096
Georg Brandlba83f822010-03-14 09:50:54 +00003097 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3098 providing correctly-rounded strtod and dtoa C functions. This code is
3099 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3100 the C compiler. There may be a small number of platforms on which correct
3101 operation of this code cannot be guaranteed, so the code is not used: notably,
3102 this applies to platforms where the C double format is not IEEE 754 binary64,
3103 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3104 and Python's configure script is unable to determine how to change the FPU
3105 precision. On these platforms conversions use the platform strtod and dtoa,
3106 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003108- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3109 uses the correctly-rounded string <-> float conversions described above (when
3110 available), and so produces correctly rounded results that will display nicely
3111 under the float repr. There are two related small changes: (1) round now
3112 accepts any class with an ``__index__()`` method for its second argument (but
3113 no longer accepts floats for the second argument), and (2) an excessively
3114 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3115 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003257
Georg Brandlba83f822010-03-14 09:50:54 +00003258 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3259 (2) parsing of strings representing infinities and nans was locale aware; and
3260 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00003261
Georg Brandlba83f822010-03-14 09:50:54 +00003262- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3263 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3264 but with at least one decimal point and with a default precision
3265 of 12. Previously, the behavior the same but with a default precision of 6.
3266 This more closely matches ``str()``, and reduces surprises when adding
3267 alignment flags to the empty presentation type. This also affects the new
3268 complex.__format__ in the same way.
3269
3270- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3271 classtype's, even if it was None. property now inserts the __doc__ into the
3272 subclass instance __dict__.

3293
Georg Brandlba83f822010-03-14 09:50:54 +00003294- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves

Antoine Pitrouf8387af2009-03-23 18:41:45 +00003332- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00003333 untrackable objects are not tracked by the garbage collector. This can reduce
3334 the size of collections and therefore the garbage collection overhead on

3342 internal representation of integers, for performance reasons. Base 2**30 is
3343 enabled by default on 64-bit machines. Add --enable-big-digits option to
3344 configure, which overrides the default. Add sys.long_info structseq to
3345 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00003446- Issue #4597: Fixed exception handling when the __exit__ function of a context
3447 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00003448
Georg Brandlba83f822010-03-14 09:50:54 +00003449- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00003450
Georg Brandlba83f822010-03-14 09:50:54 +00003451- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3452 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3453 instances. On a typical machine this saves 3 bytes of memory (on average) per
3454 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003455
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003456- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3457 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3458 instead of throwing a MemoryError.
3459
Georg Brandlba83f822010-03-14 09:50:54 +00003460- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3461 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003462
Benjamin Petersonc078f922008-11-21 22:27:24 +00003463- Issue #4367: Python would segfault during compiling when the unicodedata
3464 module couldn't be imported and \N escapes were present.
3465
Georg Brandlba83f822010-03-14 09:50:54 +00003466- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3467 file objects with closefd=False. The file descriptor is still kept open but
3468 the file object behaves like a closed file. The ``FileIO`` object also got a
3469 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003470
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003471- Issue #4348: Some bytearray methods returned that didn't cause any change to
3472 the bytearray, returned the same bytearray instead of a copy.
3473
Georg Brandlba83f822010-03-14 09:50:54 +00003474- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00003475
Benjamin Peterson273c2332008-11-17 22:39:09 +00003476- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3477
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003478- Issue #4048: The parser module now correctly validates relative imports.
3479
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003480- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3481 exec statement.
3482
Georg Brandlba83f822010-03-14 09:50:54 +00003483- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3484 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003485
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003486- Issue #4209: Enabling unicode_literals and the print_function in the same
3487 __future__ import didn't work.
3488
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003489- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003490 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003491
Georg Brandlba83f822010-03-14 09:50:54 +00003492- On windows, ``os.chdir()`` given unicode was not working if
3493 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3494 this code path is really executed because I cannot move to such directory on
3495 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003496
Georg Brandlba83f822010-03-14 09:50:54 +00003497- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3498 element is temporarily replaced with an equivalent frozenset. But the
3499 eventual KeyError would always report the empty ``frozenset()`` as the missing
3500 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003501
Georg Brandlba83f822010-03-14 09:50:54 +00003502- Issue #4509: Various issues surrounding resize of bytearray objects to which
3503 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00003504
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00003505- Issue #4748: Lambda generators no longer return a value.
3506
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00003507- Issue #3582: Use native TLS functions on Windows
3508
Gregory P. Smithae91d092009-03-02 05:13:57 +00003509- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
3510
Georg Brandlba83f822010-03-14 09:50:54 +00003511- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
3512 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00003513
Matthias Klose91a3b9e2009-04-05 21:19:13 +00003514- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3515 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003516
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003517- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3518 returned them on 64bit platforms.
3519
Walter Dörwalded960ac2009-05-03 22:36:33 +00003520- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3521 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3522 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3523 of using the replace error handler in PyUnicode_DecodeUTF8().
3524
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003525- Issue #3739: The unicode-internal encoder now reports the number of characters
3526 consumed like any other encoder (instead of the number of bytes).
3527
Georg Brandlba83f822010-03-14 09:50:54 +00003528- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3529 allocator will be automatically disabled when running under Valgrind. This
3530 gives improved memory leak detection when running under Valgrind, while taking
3531 advantage of pymalloc at other times.

3554 Patch by Jean-Paul Calderone.
Antoine Pitrou30b3b352009-12-02 20:37:54 +00003555
Tarek Ziadéa5076a22009-11-29 22:20:30 +00003556- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
3557 ownership when the group is not forced, because the group may be different
3558 from the user's group and inherit from its container when the test is run.
3559
Georg Brandlba83f822010-03-14 09:50:54 +00003560- Issue #1515: Enable use of deepcopy() with instance methods. Patch by Robert

Georg Brandlba83f822010-03-14 09:50:54 +00003600- Issue #6816: runpy now provides a run_path function that allows Python code to
3601 execute file paths that refer to source or compiled Python files as well as
3602 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00003603 __main__.py file. This allows applications that run other Python scripts to
3604 support the same flexibility as the CPython command line itself.
3605
Georg Brandlba83f822010-03-14 09:50:54 +00003606- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
3607 connection with another process, rather than looping endlessly. The default
3608 timeout is 20 seconds, which should be amply sufficient for local connections.

Antoine Pitrouaec41242009-11-02 11:34:27 +00003625 a modification is done through it. This fixes inconsistencies and test

3629 from stdin so that existing input does not confuse it and lead to incorrect
3630 entry or an IOError. It also properly flushes it afterwards to avoid the
3631 terminal echoing the input afterwards on OSes such as Solaris.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004896- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4897
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004898- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4899 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4900 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4901 ``printf`` function, whereas PyString_FromFormat has an independent
4902 implementation and uses "%zd" on all platforms for size_t values.
4903 This makes a difference on win64, where ``printf`` needs "%Id" to display
4904 64bit values.
4905
Benjamin Peterson97179b02008-09-09 20:55:01 +00004906- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4910 object; previously an int would be returned for small values. the __long__
4911 method is allowed to return either an int or a long, but the behaviour of
4912 float objects should not change to respect backward compatibility.
4913
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004914- Issue #3751: str.rpartition would perform a left-partition when called with
4915 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004920 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004921 was correctly parsed but parsing of subsequent arguments failed.
4922
Vinay Sajip35e3b032008-09-01 14:33:59 +00004923- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004924 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4925 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4926 when given a tuple of classes as second argument, were looking up
4927 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4928 type object.
4929
Neal Norwitz18aa3882008-08-24 05:04:52 +00004930- Fix crashes on memory allocation failure found with failmalloc.
4931
4932- Fix memory leaks found with valgrind and update suppressions file.
4933
4934- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004999 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5000 for catch_warnings() also led to an improvement in the raising of a

5073-----------------
5074
Guido van Rossumf8402962008-08-20 15:01:50 +00005075- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5076 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5077 extensions do not automatically benefit from the class attribute
5078 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5079 to their tp_flags field if they care. This is a backwards
5080 compatibility feature; in 3.0, all types will use the cache by
5081 default.
5082
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005083- Keyword arguments can now follow starred arguments. (``f(a, *args,
5084 keyword=23)`` is now valid syntax.)
5085
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005086- ctypes function pointers that are COM methods have a boolean True
5087 value again.
5088
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005089- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5090 by denying s# to parse objects that have a releasebuffer procedure,
5091 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00005093- Issue #3537: Fix an assertion failure when an empty but presized dict
5094 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00005096- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5097 ValueError consistently across platforms.
5098
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005099- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5100 (64bit Unix, for example), unichr() would truncate its argument and return
5101 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5102
Neal Norwitze7d8be82008-07-31 17:17:14 +00005103- Apply security patches from Apple.
5104
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005105- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00005108- Issue #1819: function calls with several named parameters are now on
5109 average 35% faster (as measured by pybench).
5110
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005111- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5112 the python debugger steps into a class statement: the free variables (local
5113 variables defined in an outer scope) would be deleted from the outer scope.
5114
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005115- Issue #2620: Overflow checking when allocating or reallocating memory
5116 was not always being done properly in some python types and extension
5117 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5118 all been updated to perform better checks and places in the code that
5119 would previously leak memory on the error path when such an allocation
5120 failed have been fixed.

5126
Benjamin Petersone977ad42008-08-20 01:42:01 +00005127- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5128 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5129
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005130- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5131 version reported by these tools does not necessarily follow the python
5132 version numbering scheme, so the module is less strict when parsing it.
5133
Nick Coghlanf70385a2008-08-18 12:42:46 +00005134- Issue #2235: Added Py3k warnings for types which will become unhashable
5135 under the stricter __hash__ inheritance rules in 3.0. Several types
5136 which did not meet the rules for hash invariants and were already
5137 unhashable in 3.0 have now been explicitly flagged as unhashable in
5138 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5139 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5140
Brett Cannon88f801d2008-08-18 00:46:22 +00005141- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5142 imported into the module but exposed as part of the module's API.
5143

5163 after a 302 response in the case of not going through a proxy.
5164
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005165- Issue #2676: in the email package, content-type parsing was hanging on
5166 pathological input because of quadratic or exponential behaviour of a
5167 regular expression.
5168
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005169- Issue #3476: binary buffered reading through the new "io" library is now
5170 thread-safe.
5171
Brett Cannonbf3157b2008-08-14 05:00:03 +00005172- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5173 since mimetools itself is deprecated. Because modules are cached, all
5174 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5175
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005176- Issue #3134: shutil referenced undefined WindowsError symbol.

5179 menu entries were not deleted.
5180
Brett Cannon83e81842008-08-09 23:30:55 +00005181- Copied the implementation of reduce() to _functools.reduce() to have a

5183
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005184- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5185 a MemoryError rather than silently stop the iteration.
5186
Guido van Rossum59ce9012008-08-09 14:55:34 +00005187- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5188 to _sre.compile() will now be rejected. This should not affect anybody
5189 since the re.compile() function never generates invalid re-bytecode.
5190
Skip Montanaroa032bf42008-08-08 22:52:51 +00005191- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5192 upon first access it can be automatically initialized from the csv file if
5193 it wasn't initialized during instantiation.
5194
Brett Cannon3aa2a492008-08-06 22:28:09 +00005195- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5196 the reload() built-in has been removed.
5197
Brett Cannon7e30b672008-08-04 21:52:25 +00005198- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005199 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5207 raised an AttributeError.
5208
Benjamin Peterson01a24322008-07-28 23:35:27 +00005209- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005210 asking for a specific length. This problem only affected files opened
5211 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005212

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005236- Issue #3394: zipfile.writestr sets external attributes when passed a
5237 file name rather than a ZipInfo instance, so files are extracted with
5238 mode 0600 rather than 000 under Unix.
5239
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005240- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5241 argument in python 2.5, this broke code that subclassed Popen to include its
5242 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005252- Issue #2235: the C API function PyObject_HashNotImplemented and its
5253 interaction with the tp_hash slot (added in 2.6b2) are now documented
5254
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005255- Issue #643841: The language reference now provides more detailed
5256 coverage of the lookup process for special methods. The disclaimers
5257 regarding lack of coverage of new-style classes have also been
5258 removed, since the coverage is now fairly reasonable.

5262================================
5263
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005264*Release date: 17-Jul-2008*
5265
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005266Core and Builtins
5267-----------------
5268
Georg Brandl3e483f62008-07-16 22:57:41 +00005269- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5270 its methods now allow for items objects that can be converted to
5271 an integer using operator.index().
5272
Mark Dickinson64b7e502008-07-16 09:40:03 +00005273- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5274 produced a ValueError instead of giving the correct float.
5275
Eric Smitha5fa5a22008-07-16 00:11:49 +00005276- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5277 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5278
Mark Dickinson7103aa42008-07-15 19:08:33 +00005279- Issue #3008: the float type has a new instance method 'float.hex'
5280 and a new class method 'float.fromhex' to convert floating-point
5281 numbers to and from hexadecimal strings, respectively.
5282
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005283- Issue #2235: __hash__ is once again inherited by default. To allow
5284 collections.Hashable to remain meaningful in the presence of the
5285 default hash implementation (object.__hash__), it is now possible
5286 to explicit block inheritance of hash by setting __hash__=None at
5287 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5288 level.
5289
Nick Coghlanb028f502008-07-13 14:52:36 +00005290- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5291 the parent module cannot be found while performing an absolute import.
5292 This means that an incorrectly defined __package__ attribute will
5293 now only prevent relative imports in that module rather than causing
5294 all imports from that module to fail.
5295
Nick Coghlan14ff9942008-07-08 14:21:42 +00005296- Issue #2517: Allow unicode messages in Exceptions again by correctly
5297 bypassing the instance dictionary when looking up __unicode__ on
5298 new-style classes.
5299
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005300- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5301 set to a custom object whose write() method happens to install
5302 another file in sys.stdout.
5303
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005304- Issue #3088: Corrected a race condition in classes derived from
5305 threading.local: the first member set by a thread could be saved in
5306 another thread's dictionary.
5307
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005308- Issue #3004: Minor change to slice.indices(): the start and stop
5309 arguments are now treated identically, making the behaviour easier
5310 to describe and understand. For example, slice(None, -10,
5311 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5312 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5313 10, -1).
5314
Georg Brandl278fc502008-07-19 12:46:12 +00005315- Issue #3219: Calling a function with repeated keyword arguments,
5316 f(a=2, a=23), would not cause a syntax error. This was a regression
5317 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005318
Georg Brandl278fc502008-07-19 12:46:12 +00005319- Issue #2862: Make int and float freelist management consistent with
5320 other freelists. Changes their CompactFreeList apis into
5321 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005322

5324-------
5325
Thomas Heller57adf222008-08-14 19:10:48 +00005326- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5327 api functions without holding the GIL, which could lead to a fatal
5328 error when they failed.
5329
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005330- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005338- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5339 ForkingPickler.register() to resolve conflict with ctypes.
5340
Vinay Sajip51e65192008-07-18 09:01:10 +00005341- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005342
Thomas Heller880f5292008-07-15 19:39:38 +00005343- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5344 a valid dlerror() message.
5345
Thomas Heller2bad6572008-07-15 17:19:50 +00005346- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5347 incomplete structure was created.
5348

5352
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005353- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005354
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005355- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5356 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005357 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005358 content-length. The problem had been corrected in the 2.4 branch, but never
5359 merged into trunk.
5360
Georg Brandle78fbcc2008-07-05 10:13:36 +00005361- Issue #2663: add filtering capability to shutil.copytree().

5368 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00005369 Zip files with archives by setting the 'comment' attribute of a ZipFile.

Vinay Sajip51e65192008-07-18 09:01:10 +00005371- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005372 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005373
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005374- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5375 handling is now the same as that of other special attributes like __name__).
5376
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005377- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5378 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00005767 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005768
5769 This is controlled by the configure argument ``--with-universal-archs``:
5770
5771 - ``--with-universal-archs=all``: install 4-way universal
5772
5773 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5774
5775 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5776
5777 This option should be used in combination with ``--enable-universalsdk=``.
5778
5779 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 +00005829- Issue #1631171: Re-implement the 'warnings' module in C (the
5830 original Python code has been kept as backup). This will allow for
5831 using the 'warning's machinery in such places as the parser where
5832 use of pure Python code is not possible. Both the ``showarning()``
5833 and ``formatwarning()`` gain an optional 'line' argument which is
5834 not called by default for backwards-compatibility reasons. Setting
5835 ``warnings.showwarning()`` to an implementation that lacks support
5836 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005899- Issue #2550: The approach used by client/server code for obtaining
5900 ports to listen on in network-oriented tests has been refined in an
5901 effort to facilitate running multiple instances of the entire
5902 regression test suite in parallel without issue.
5903 test_support.bind_port() has been fixed such that it will always
5904 return a unique port -- which wasn't always the case with the
5905 previous implementation, especially if socket options had been set
5906 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5907 new implementation of bind_port() will actually raise an exception
5908 if it is passed an AF_INET/SOCK_STREAM socket with either the
5909 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5910 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5911 the socket it's been passed. This currently only applies to
5912 Windows. This option prevents any other sockets from binding to the
5913 host/port we've bound to, thus removing the possibility of the
5914 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5915 when a second SOCK_STREAM socket binds and accepts to a host/port
5916 that's already been bound by another socket. The optional preferred
5917 port parameter to bind_port() has been removed. Under no
5918 circumstances should tests be hard coding ports!
5919
5920 test_support.find_unused_port() has also been introduced, which will
5921 pass a temporary socket object to bind_port() in order to obtain an
5922 unused port. The temporary socket object is then closed and
5923 deleted, and the port is returned. This method should only be used
5924 for obtaining an unused port in order to pass to an external program
5925 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5926 a parameter to a server-oriented class that doesn't give you direct
5927 access to the underlying socket used.
5928
5929 Finally, test_support.HOST has been introduced, which should be used
5930 for the host argument of any relevant socket calls (i.e. bind and
5931 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005932
5933 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005934 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

5936 test_asynchat and test_socket_ssl.
5937
Georg Brandl3ee81df2008-05-17 18:14:43 +00005938 It is now possible for multiple instances of the regression test
5939 suite to run in parallel without issue.

6205Core and builtins
6206-----------------
6207
Fred Drakea8ee94b2008-03-01 02:45:07 +00006208- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006209 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006210
Georg Brandlad61bc82008-02-23 15:11:18 +00006211- Issue #2067: file.__exit__() now calls subclasses' close() method.
6212
6213- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006214
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006215- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006216 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006217
Eric Smitha73fbe72008-02-23 03:09:44 +00006218- Added the future_builtins module, which contains hex() and oct().
6219 These are the PEP 3127 version of these functions, designed to be
6220 compatible with the hex() and oct() builtins from Python 3.0. They
6221 differ slightly in their output formats from the existing, unchanged
6222 Python 2.6 builtins. The expected usage of the future_builtins
6223 module is:
6224 from future_builtins import hex, oct
6225
Eric Smith7ef40bf2008-02-20 23:34:22 +00006226- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6227 exponents for exponents with absolute value < 100. Follows C99
6228 standard. This is a change on Windows, which would use 3 digits.
6229 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6230 so that any alterations it does to the resulting string will be
6231 available in stringlib/formatter.h (for float.__format__).
6232
Eric Smith5a3c1352008-02-19 13:21:56 +00006233- Implemented PEP 3101, Advanced String Formatting. This adds a new
6234 builtin format(); a format() method for str and unicode; a
6235 __format__() method to object, str, unicode, int, long, float, and
6236 datetime; the class string.Formatter; and the C API
6237 PyObject_Format().
6238
Georg Brandl3ee81df2008-05-17 18:14:43 +00006239- Fixed several potential crashes, all caused by specially crafted
6240 __del__ methods exploiting objects in temporarily inconsistent
6241 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006242
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006243- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006244 prevent a possible crash: an Abstract Base Class would try to access
6245 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006246
Georg Brandl3ee81df2008-05-17 18:14:43 +00006247- Fixed repr() and str() of complex numbers with infinity or nan as
6248 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006249
Georg Brandl3ee81df2008-05-17 18:14:43 +00006250- Clear all free lists during a gc.collect() of the highest generation
6251 in order to allow pymalloc to free more arenas. Python may give back
6252 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006253
Georg Brandl3ee81df2008-05-17 18:14:43 +00006254- Issue #2045: Fix an infinite recursion triggered when printing a
6255 subclass of collections.defaultdict, if its default_factory is set
6256 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006257
Christian Heimesf75dbef2008-02-08 00:11:31 +00006258- Fixed a minor memory leak in dictobject.c. The content of the free
6259 list was not freed on interpreter shutdown.
6260
Georg Brandl21e99f42010-03-07 15:23:59 +00006261- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006262 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006263
Georg Brandl3ee81df2008-05-17 18:14:43 +00006264- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6265 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006266 to compact the internal free lists of pre-allocted ints and floats.
6267
Georg Brandl3ee81df2008-05-17 18:14:43 +00006268- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6269 calls. Python expected the return type int but the fork familie
6270 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006271
Georg Brandl3ee81df2008-05-17 18:14:43 +00006272- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6273 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006274
Georg Brandl3ee81df2008-05-17 18:14:43 +00006275- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6276 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006277
Georg Brandl3ee81df2008-05-17 18:14:43 +00006278- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6279 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006280
Georg Brandl3ee81df2008-05-17 18:14:43 +00006281- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6282 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006283
Georg Brandl3ee81df2008-05-17 18:14:43 +00006284- Patch #1473257: generator objects gain a gi_code attribute. This is
6285 the same object as the func_code attribute of the function that
6286 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006287
Georg Brandl3ee81df2008-05-17 18:14:43 +00006288- Issue #1920: "while 0" statements were completely removed by the
6289 compiler, even in the presence of an "else" clause, which is
6290 supposed to be run when the condition is false. Now the compiler
6291 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006292
Guido van Rossumeead05f2008-01-24 18:21:02 +00006293- A few crashers fixed: weakref_in_del.py (issue #1377858);
6294 loosing_dict_ref.py (issue #1303614, test67.py);
6295 borrowed_ref_[34].py (not in tracker).
6296
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006297- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006298 suppressed while an extension is loaded by calling SetErrorMode in
6299 dynload_win.c. The error is still reported properly.
6300
Georg Brandl3ee81df2008-05-17 18:14:43 +00006301- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006302 several extension methods and modules do not work without unicode
6303 support.
6304
Georg Brandl26543b12008-01-21 18:36:51 +00006305- Issue #1882: when compiling code from a string, encoding cookies in the
6306 second line of code were not always recognized correctly.
6307
Georg Brandl14404b62008-01-19 19:27:05 +00006308- Issue #1679: "0x" was taken as a valid integer literal.
6309
Georg Brandl6caad7d2008-01-26 14:19:22 +00006310- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006311 added.
6312
Christian Heimesc94e2b52008-01-14 04:13:37 +00006313- sys.float_info / PyFloat_GetInfo: The floating point information
6314 object was converted from a dict to a specialized structseq object.
6315
Georg Brandl3ee81df2008-05-17 18:14:43 +00006316- Patch #1816: Added sys.flags structseq. It exposes the status of
6317 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006318
Georg Brandl3ee81df2008-05-17 18:14:43 +00006319- Objects/structseq.c: Implemented new structseq representation. The
6320 patch makes structseqs (e.g. the return value of os.stat) more
6321 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006322
Georg Brandl3ee81df2008-05-17 18:14:43 +00006323- Patch #1700288: added a type attribute cache that caches method
6324 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006325
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006326- Bug #1776: __import__() no longer accepts filenames on any platform.
6327 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006328
Georg Brandlaed6c662008-01-07 17:25:53 +00006329- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6330
Georg Brandl3ee81df2008-05-17 18:14:43 +00006331- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6332 envvar and sys.dont_write_bytecode attribute. All these can be set
6333 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006334
Georg Brandl3ee81df2008-05-17 18:14:43 +00006335- Improve some exception messages when Windows fails to load an
6336 extension module. Now we get for example '%1 is not a valid Win32
6337 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006338
Georg Brandl3ee81df2008-05-17 18:14:43 +00006339- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006341- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6342 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006343
Christian Heimes0a8143f2007-12-18 23:22:54 +00006344- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006345 and INF. float("nan"), float("inf") and float("-inf") now work on
6346 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006347
Georg Brandl3ee81df2008-05-17 18:14:43 +00006348- Compiler now generates simpler and faster code for dictionary
6349 literals. The oparg for BUILD_MAP now indicates an estimated
6350 dictionary size. There is a new opcode, STORE_MAP, for adding
6351 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006352
Georg Brandl3ee81df2008-05-17 18:14:43 +00006353- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006358- Issue #1538: Avoid copying string in split/rsplit if the split char
6359 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006360
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006361- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006362 SystemError.
6363
Nick Coghlanef01d822007-12-03 12:55:17 +00006364- PEP 366: Allow explicit relative imports when executing modules
6365 inside packages with the -m switch via a new module level
6366 __package__ attribute.
6367
Georg Brandl3ee81df2008-05-17 18:14:43 +00006368- Issue #1402: Fix a crash on exit, when another thread is still
6369 running, and if the deallocation of its frames somehow calls the
6370 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006371

6381 file can now be directly executed by passing their name to the
6382 interpreter. The directory/zipfile is automatically inserted as the
6383 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006384
Georg Brandl3ee81df2008-05-17 18:14:43 +00006385- Issue #1265: Fix a problem with sys.settrace, if the tracing
6386 function uses a generator expression when at the same time the
6387 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006388
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006389- sets and frozensets now have an isdisjoint() method.
6390
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006391- optimize the performance of builtin.sum().
6392
Neal Norwitz44f326e2007-10-05 05:29:17 +00006393- Fix warnings found by the new version of the Coverity checker.
6394
Georg Brandl21e99f42010-03-07 15:23:59 +00006395- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006396 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6397 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006398
Georg Brandl3ee81df2008-05-17 18:14:43 +00006399- Issue #1686386: Tuple's tp_repr did not take into account the
6400 possibility of having a self-referential tuple, which is possible
6401 from C code. Nor did object's tp_str consider that a type's tp_str
6402 could do something that could lead to an inifinite recursion.
6403 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6404 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006405
Georg Brandl3ee81df2008-05-17 18:14:43 +00006406- Issue #1164: It was possible to trigger deadlock when using the
6407 'print' statement to write to a file since the GIL was not released
6408 as needed. Now PyObject_Print() does the right thing along with
6409 various tp_print implementations of the built-in types and those in
6410 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006411
Georg Brandl3ee81df2008-05-17 18:14:43 +00006412- Issue #1147: Exceptions were directly allowing string exceptions in
6413 their throw() method even though string exceptions no longer
6414 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006415

Brett Cannon1e534b52007-09-07 04:18:30 +00006419- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006420 PyObject_Call() never calling back out to Python code to trigger
6421 recursion depth updates/checks. Required the creation of a static
6422 RuntimeError instance in case normalizing an exception put the
6423 recursion check value past its limit. Fixes crashers
6424 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006425
Georg Brandl3ee81df2008-05-17 18:14:43 +00006426- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006439- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006440 __*__ attributes. (Some already existed, e.g., __doc__ and
6441 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006442
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006443- Add -3 option to the interpreter to warn about features that are

6447 calls.
6448
Collin Winter62903052007-05-18 23:11:24 +00006449- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006450 "except E as target:". This is to provide forwards compatibility
6451 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006452
Brett Cannon229cee22007-05-05 01:34:02 +00006453- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006458- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006459 setting a plain string, ie don't expand to single letter identifiers.
6460
Raymond Hettinger13936692007-04-11 18:40:58 +00006461- Request #1191699: Slices can now be pickled.

6471
Guido van Rossum143b5642007-03-23 04:58:42 +00006472- Bug #1683368: The object.__init__() and object.__new__() methods are
6473 now stricter in rejecting excess arguments. The only time when
6474 either allows excess arguments is when it is not overridden and the
6475 other one is. For backwards compatibility, when both are
6476 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006477 warning later). Also, type.__init__() insists on the same signature
6478 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006479
Georg Brandl3ee81df2008-05-17 18:14:43 +00006480- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6481 object to complex using its __complex__() method before falling back
6482 to the __float__() method. Therefore, the functions in the cmath
6483 module now can operate on objects that define a __complex__()
6484 method.

6501
Georg Brandl7b9c5552007-03-12 14:30:05 +00006502- Bug #1678647: write a newline after printing an exception in any
6503 case, even when converting the value to a string failed.
6504
Georg Brandl871f1bc2007-03-12 13:17:36 +00006505- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006506 its argument, if it exists. If not, it will work like before. This
6507 allows customizing the output of dir() in the presence of a
6508 __getattr__().

6517 parthensized forms. This means complex(repr(x)) now works instead of
6518 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006519
Georg Brandlaa2321b2007-03-07 00:40:28 +00006520- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006521 makes the filenames the warning module prints much more sensible
6522 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006523

Georg Brandl0fca97a2007-03-05 22:28:08 +00006535- Patch #1674228: when assigning a slice (old-style), check for the
6536 sq_ass_slice instead of the sq_slice slot.
6537
Georg Brandl3ee81df2008-05-17 18:14:43 +00006538- When printing an unraisable error, don't print exceptions. before
6539 the name. This duplicates the behavior whening normally printing
6540 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007073 AttributeError instead of an IOError when the server's response
7074 didn't contain a valid HTTP status line.

7165 TestCase and TestSuite subclasses (not instances) are no longer
7166 accepted in TestSuite.addTest(). This should cause no

7168 -- the failure just occurred later, with a more cumbersome

Georg Brandl3ee81df2008-05-17 18:14:43 +00007450- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7451 with RFC 3207 and forgets any knowledge obtained from the server not
7452 obtained from the TLS negotiation itself. Patch contributed by Bill
7453 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007454
Georg Brandl3ee81df2008-05-17 18:14:43 +00007455- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007456 that the SMTP.starttls() caller no longer needs to call ehlo()
7457 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007458 does not claim to support starttls. Adds the
7459 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7540 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7541 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007558 time so that opening a database previously created with the DB_DUP
7559 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7560 opens. Specifically: dictionary assignment to a DB object will
7561 replace all values for a given key when the database allows
7562 duplicate values. DB users should use DB.put(k, v) when they want
7563 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007564

7570 characters with ASCII value less than 32. Also, it correctly quotes
7571 dots only if they occur on a single line, as opposed to the previous
7572 behavior of quoting dots if they are the second character of any
7573 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007574

Georg Brandl3ee81df2008-05-17 18:14:43 +00007903- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7904 to ``PyTuple_SetItem``, it can be used to populate a brand new
7905 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00007907- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007909- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7910 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7911 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007912
7913- Patch #1720595: add T_BOOL to the range of structmember types.
7914
7915- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7916 ``PyFloat_GetInfo()`` to the float API.
7917
Georg Brandl3ee81df2008-05-17 18:14:43 +00007918- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7919 of w# format code incorrectly truncated the length to an int, even
7920 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7921 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007922
Georg Brandl3ee81df2008-05-17 18:14:43 +00007923- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7924 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007925
Georg Brandl3ee81df2008-05-17 18:14:43 +00007926- PEP 3123: Provide forward compatibility with Python 3.0, while
7927 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7928 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007929
Georg Brandl3ee81df2008-05-17 18:14:43 +00007930- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7931 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007932
7933- Patch #1733960: Allow T_LONGLONG to accept ints.
7934
7935- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7936
Christian Heimes000a0742008-01-03 22:16:32 +00007937- Added a new API function ``PyImport_ImportModuleNoBlock``.
7938
Georg Brandl6caad7d2008-01-26 14:19:22 +00007939- Bug #1637022: Prefix AST symbols with _Py_.
7940
7941- Fix some leftovers from the conversion from int to Py_ssize_t
7942 (relevant to strings and sequences of more than 2**31 items).
7943
7944- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7945 outside of pystate.c and should not be necessary.
7946
Georg Brandl3ee81df2008-05-17 18:14:43 +00007947- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7948 absolute imports. In earlier versions they might have used relative
7949 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007950
Georg Brandl3ee81df2008-05-17 18:14:43 +00007951- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7952 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007953
Georg Brandl3ee81df2008-05-17 18:14:43 +00007954- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7955 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007961- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7962 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7963 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7964 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007965
Georg Brandl3ee81df2008-05-17 18:14:43 +00007966- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
7967 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00007977- buildtools now raises a DeprecationWarning.
7978
Georg Brandl3ee81df2008-05-17 18:14:43 +00007979- Removed the macfs module. It had been deprecated since Python 2.5.
7980 This lead to the deprecation of macostools.touched() as it relied
7981 solely on macfs and was a no-op under OS X.
