Antoine Pitrou5b4b2da2011-12-15 14:15:31 +0100336- Fix the fix for issue #12149: it was incorrect, although it had the side
337 effect of appearing to resolve the issue. Thanks to Mark Shannon for

Mark Dickinsondbbed042011-09-19 16:38:08 +0100370- Issue #12973: Fix overflow checks that invoked undefined behaviour in
371 int.__pow__. These overflow checks were causing int.__pow__ to produce
372 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100373 compiler optimizing the check away. Also fix similar overflow checks
374 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
375 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +0200386- Issue #12149: Update the method cache after a type's dictionnary gets
387 cleared by the garbage collector. This fixes a segfault when an instance
388 and its type get caught in a reference cycle, and the instance's
389 deallocator calls one of the methods on the type (e.g. when subclassing
390 IOBase). Diagnosis and patch by Davide Rizzo.

Victor Stinner08563d92011-05-30 23:44:13 +0200399 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
400 raw_input() interrupted by CTRL+c.
401
Łukasz Langa7a153902011-10-18 17:16:00 +0200402- Issue #10860: httplib now correctly handles an empty port after port
403 delimiter in URLs.
404

Florent Xiclunac2279652012-02-12 14:49:03 +0100443- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100444 has left two versions of customize_compiler, the original in
445 distutils.sysconfig and another copy in distutils.ccompiler, with some

448 is the case in 3.x.
449
Ned Deily0d0ea482012-02-10 12:59:06 +0100450- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
451 Distutils-based packages with C extension modules may fail because
452 Apple has removed gcc-4.2, the version used to build python.org
453 64-bit/32-bit Pythons. If the user does not explicitly override
454 the default C compiler by setting the CC environment variable,
455 Distutils will now attempt to compile extension modules with clang
456 if gcc-4.2 is required but not found. Also as a convenience, if
457 the user does explicitly set CC, substitute its value as the default
458 compiler in the Distutils LDSHARED configuration variable for OS X.
459 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
460 SDK, neither of which are available in Xcode 4. This change does not
461 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700734- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
735 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
736 interpreter process. This could cause failures in non-Distutils subprocesses
737 and was unreliable since tests or user programs could modify the interpreter
738 environment after Distutils set it. Instead, have Distutils set the the
739 deployment target only in the environment of each build subprocess. It is
740 still possible to globally override the default by setting
741 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
742 greater or equal to the default value, the value with which the interpreter
743 was built.

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

1725 This prevents user-created self-referencing ordered dictionaries from
1726 becoming permanently uncollectable GC garbage. The downside is that

2187
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002188- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2189 start byte and the continuation byte(s) are now considered invalid, instead
2190 of the number of bytes specified by the start byte.
2191 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2192 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2193 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2194 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002202- Issue #8748: Fix two issues with comparisons between complex and integer
2203 objects. (1) The comparison could incorrectly return True in some cases
2204 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2205 (2) The comparison raised an OverflowError for large integers, leading
2206 to unpredictable exceptions when combining integers and complex objects
2207 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00002209- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00002346- Issue #1533: Fix inconsistency in range function argument processing: any
2347 non-float non-integer argument is now converted to an integer (if possible)
2348 using its __int__ method. Previously, only small arguments were treated this
2349 way; larger arguments (those whose __int__ was outside the range of a C long)
2350 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00002358 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00002359 benefit compared to the dynamic memory allocation fallback. Patch by

2385 messages when accessing undefined class attributes because of the cheap
2386 inheritance with the underlying socket object. The cheap inheritance has been
2387 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00002400- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2401 operation raises multiple signals and more than one of those signals is
2402 trapped, the specification determines the order in which the signals should be
2403 handled. In many cases this order wasn't being followed, leading to the wrong
2404 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00002405

2572-----------------
2573
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002574- Issue #7301: Add environment variable $PYTHONWARNINGS.
2575
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002576- Issue #8329: Don't return the same lists from select.select when no fds are
2577 changed.
2578
Georg Brandlfee0f442010-05-22 21:26:21 +00002579- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002580 on 64-bit machines. The shift count for either left or right shift is
2581 permitted to be up to sys.maxsize.
2582
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002583- Ensure that tokenization of identifiers is not affected by locale.
2584
Georg Brandlfee0f442010-05-22 21:26:21 +00002585- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002586
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002587- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2588
Georg Brandlfee0f442010-05-22 21:26:21 +00002589- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2590 with a non-empty format string. This is an effort to future-proof user
2591 code. If a derived class does not currently implement __format__ but later
2592 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002593 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002594 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002595
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002596- Issue #8268: Old-style classes (not just instances) now support weak
2597 references.
2598
Georg Brandlfee0f442010-05-22 21:26:21 +00002599- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2600 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00002601
Victor Stinnerc7790ed2010-03-22 12:36:28 +00002602- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00002603
Benjamin Peterson96545892010-03-21 20:21:00 +00002604- Issue #6474: Make error message from passing an inadequate number of keyword
2605 arguments to a function correct.
2606
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002607- Issue #8164: Don't allow lambda functions to have a docstring.
2608
Victor Stinner66644262010-03-10 22:30:19 +00002609- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002610 (SIGINT). If an error occurs while importing the site module, the error is
2611 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002612 module.
2613
Collin Winter001a3952010-03-18 21:54:01 +00002614- Code objects now support weak references.

2617-------
2618
R. David Murray661303f2010-04-13 20:57:40 +00002619- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
2620
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002621- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002622 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2623 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002624
Benjamin Peterson76a23c12010-04-04 23:23:22 +00002625- Issue #8310: Allow dis to examine new style classes.
2626
Georg Brandlfee0f442010-05-22 21:26:21 +00002627- Issue #8257: The Decimal construct now accepts a float instance directly,
2628 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002629
2630 >>> Decimal(1.1)
2631 Decimal('1.100000000000000088817841970012523233890533447265625')
2632
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002633- collections.Counter() now supports a subtract() method.
2634
Georg Brandlfee0f442010-05-22 21:26:21 +00002635- The functools module now has a total_ordering() class decorator to simplify
2636 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002637
Georg Brandlfee0f442010-05-22 21:26:21 +00002638- The functools module also adds cmp_to_key() as a tool to transition old-style
2639 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002640
Georg Brandlfee0f442010-05-22 21:26:21 +00002641- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2642 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002643
Georg Brandlfee0f442010-05-22 21:26:21 +00002644- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2645 InvalidOperation instead of returning False. (Comparisons involving a quiet
2646 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2647 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002648
Georg Brandlfee0f442010-05-22 21:26:21 +00002649- Issue #2531: Comparison operations between floats and Decimal instances now
2650 return a result based on the numeric values of the operands; previously they
2651 returned an arbitrary result based on the relative ordering of id(float) and
2652 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002653
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002654- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002655 argument `-` which tells it to read files to compile from stdin. Each line is
2656 read on demand and the named file is compiled immediately. (Original patch by
2657 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002658
Georg Brandlfee0f442010-05-22 21:26:21 +00002659- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2660 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002662- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2663 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002664 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002665
Georg Brandlfee0f442010-05-22 21:26:21 +00002666- Comparisons using one of <, <=, >, >= between a complex instance and a
2667 Fractions instance now raise TypeError instead of returning True/False. This
2668 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2669 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002670
Michael Foorde6410c52010-03-29 20:04:23 +00002671- Addition of ``WeakSet`` to the ``weakref`` module.

2679
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002680- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002681 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2682 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002683
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002684- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2685 deprecated.
2686
Georg Brandlfee0f442010-05-22 21:26:21 +00002687- Issue #7860: platform.uname now reports the correct 'machine' type when Python
2688 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00002689

2694 existing at the same time, causing a Unicode error when configuration code
2695 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00002696
Georg Brandlfee0f442010-05-22 21:26:21 +00002697- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
2698 when logging occurs.

2701 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
2702 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00002703
Florent Xiclunacf82fa62010-03-21 12:27:20 +00002704- Issue #8179: Fix macpath.realpath() on a non-existing path.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002724- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002725 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2726 log file to compute the next rollover time. If the log file does not exist,
2727 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002728

2736
Georg Brandlba83f822010-03-14 09:50:54 +00002737- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2738 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2739 This is a behavior change, so email's minor version number is now bumped, to
2740 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002768- Issue #8300: When passing a non-integer argument to struct.pack with any
2769 integer format code, struct.pack first attempts to convert the non-integer
2770 using its __index__ method. If that method is non-existent or raises
2771 TypeError it goes on to try the __int__ method, as described below.
2772
Georg Brandlba83f822010-03-14 09:50:54 +00002773- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2774 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2775 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002776 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2777 inconsistent: __int__ was used for some integer codes but not for others, and
2778 the set of integer codes for which it was used differed between native packing
2779 and standard packing.)

3046 numeric strings corresponding to subnormal values,
3047 (3) a memory leak for some values large enough to cause overflow, and
3048 (4) a number of flaws that could lead to incorrectly rounded results.

3183Core and Builtins
3184-----------------
3185
Georg Brandlba83f822010-03-14 09:50:54 +00003186- The ``__complex__()`` method is now looked up on the class of instances to
3187 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003189- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

3191
Mark Dickinson1b34d252010-01-01 17:27:30 +00003192- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003193 DeprecationWarning when passed a float argument where an integer was expected.
3194 These functions and methods now raise TypeError instead. The majority of the
3195 effects of this change are in the extension modules, but some core functions
3196 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3197 and many unicode/str methods.

3211 of integers: the result of a/b is now correctly rounded for ints a and b (at
3212 least on IEEE 754 platforms), and in particular does not depend on the
3213 internal representation of a long.

3221
Georg Brandlba83f822010-03-14 09:50:54 +00003222 These executables now work properly with the arch(1) command: ``arch -ppc
3223 python`` will start a universal binary version of python in PPC mode (unlike

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003365

3367 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00003380- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3381 decimal string that's guaranteed to round back to x under correct rounding
3382 (with round-half-to-even rounding mode). Previously it gave a string based on
3383 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3384 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3385 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003386
Georg Brandlba83f822010-03-14 09:50:54 +00003387- Issue #7117: On almost all platforms: float-to-string and string-to-float
3388 conversions within Python are now correctly rounded. Places these conversions
3389 occur include: str for floats and complex numbers; the float and complex
3390 constructors; old-style and new-style numeric formatting; serialization and
3391 deserialization of floats and complex numbers using marshal, pickle and json;
3392 parsing of float and imaginary literals in Python code; Decimal-to-float
3393 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003394
Georg Brandlba83f822010-03-14 09:50:54 +00003395 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3396 providing correctly-rounded strtod and dtoa C functions. This code is
3397 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3398 the C compiler. There may be a small number of platforms on which correct
3399 operation of this code cannot be guaranteed, so the code is not used: notably,
3400 this applies to platforms where the C double format is not IEEE 754 binary64,
3401 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3402 and Python's configure script is unable to determine how to change the FPU
3403 precision. On these platforms conversions use the platform strtod and dtoa,
3404 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003406- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3407 uses the correctly-rounded string <-> float conversions described above (when
3408 available), and so produces correctly rounded results that will display nicely
3409 under the float repr. There are two related small changes: (1) round now
3410 accepts any class with an ``__index__()`` method for its second argument (but
3411 no longer accepts floats for the second argument), and (2) an excessively
3412 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3413 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003555
Georg Brandlba83f822010-03-14 09:50:54 +00003556 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3557 (2) parsing of strings representing infinities and nans was locale aware; and
3558 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00003559
Georg Brandlba83f822010-03-14 09:50:54 +00003560- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3561 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3562 but with at least one decimal point and with a default precision
3563 of 12. Previously, the behavior the same but with a default precision of 6.
3564 This more closely matches ``str()``, and reduces surprises when adding
3565 alignment flags to the empty presentation type. This also affects the new
3566 complex.__format__ in the same way.
3567
3568- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3569 classtype's, even if it was None. property now inserts the __doc__ into the
3570 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00003631 untrackable objects are not tracked by the garbage collector. This can reduce

3640 internal representation of integers, for performance reasons. Base 2**30 is
3641 enabled by default on 64-bit machines. Add --enable-big-digits option to
3642 configure, which overrides the default. Add sys.long_info structseq to

Georg Brandlba83f822010-03-14 09:50:54 +00003744- Issue #4597: Fixed exception handling when the __exit__ function of a context
3745 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00003746
Georg Brandlba83f822010-03-14 09:50:54 +00003747- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00003748
Georg Brandlba83f822010-03-14 09:50:54 +00003749- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3750 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3751 instances. On a typical machine this saves 3 bytes of memory (on average) per
3752 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003753
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003754- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3755 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3756 instead of throwing a MemoryError.
3757
Georg Brandlba83f822010-03-14 09:50:54 +00003758- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3759 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003760
Benjamin Petersonc078f922008-11-21 22:27:24 +00003761- Issue #4367: Python would segfault during compiling when the unicodedata
3762 module couldn't be imported and \N escapes were present.
3763
Georg Brandlba83f822010-03-14 09:50:54 +00003764- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3765 file objects with closefd=False. The file descriptor is still kept open but
3766 the file object behaves like a closed file. The ``FileIO`` object also got a
3767 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003768
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003769- Issue #4348: Some bytearray methods returned that didn't cause any change to
3770 the bytearray, returned the same bytearray instead of a copy.
3771
Georg Brandlba83f822010-03-14 09:50:54 +00003772- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00003773
Benjamin Peterson273c2332008-11-17 22:39:09 +00003774- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3775
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003776- Issue #4048: The parser module now correctly validates relative imports.
3777
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003778- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3779 exec statement.
3780
Georg Brandlba83f822010-03-14 09:50:54 +00003781- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3782 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003783
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003784- Issue #4209: Enabling unicode_literals and the print_function in the same
3785 __future__ import didn't work.
3786
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003787- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003788 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003789
Georg Brandlba83f822010-03-14 09:50:54 +00003790- On windows, ``os.chdir()`` given unicode was not working if
3791 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3792 this code path is really executed because I cannot move to such directory on
3793 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003794
Georg Brandlba83f822010-03-14 09:50:54 +00003795- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3796 element is temporarily replaced with an equivalent frozenset. But the
3797 eventual KeyError would always report the empty ``frozenset()`` as the missing
3798 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003799
Georg Brandlba83f822010-03-14 09:50:54 +00003800- Issue #4509: Various issues surrounding resize of bytearray objects to which
3801 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00003802
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00003803- Issue #4748: Lambda generators no longer return a value.
3804
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00003805- Issue #3582: Use native TLS functions on Windows
3806
Gregory P. Smithae91d092009-03-02 05:13:57 +00003807- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
3808
Georg Brandlba83f822010-03-14 09:50:54 +00003809- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
3810 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00003811
Matthias Klose91a3b9e2009-04-05 21:19:13 +00003812- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3813 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003814
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003815- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3816 returned them on 64bit platforms.
3817
Walter Dörwalded960ac2009-05-03 22:36:33 +00003818- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3819 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3820 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3821 of using the replace error handler in PyUnicode_DecodeUTF8().
3822
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003823- Issue #3739: The unicode-internal encoder now reports the number of characters
3824 consumed like any other encoder (instead of the number of bytes).
3825
Georg Brandlba83f822010-03-14 09:50:54 +00003826- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3827 allocator will be automatically disabled when running under Valgrind. This
3828 gives improved memory leak detection when running under Valgrind, while taking
3829 advantage of pymalloc at other times.

Antoine Pitrou30b3b352009-12-02 20:37:54 +00003853
Tarek Ziadéa5076a22009-11-29 22:20:30 +00003854- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
3855 ownership when the group is not forced, because the group may be different
3856 from the user's group and inherit from its container when the test is run.
3857

Georg Brandlba83f822010-03-14 09:50:54 +00003898- Issue #6816: runpy now provides a run_path function that allows Python code to
3899 execute file paths that refer to source or compiled Python files as well as
3900 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00003901 __main__.py file. This allows applications that run other Python scripts to
3902 support the same flexibility as the CPython command line itself.
3903
Georg Brandlba83f822010-03-14 09:50:54 +00003904- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
3905 connection with another process, rather than looping endlessly. The default
3906 timeout is 20 seconds, which should be amply sufficient for local connections.

Antoine Pitrouaec41242009-11-02 11:34:27 +00003923 a modification is done through it. This fixes inconsistencies and test

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00005175 AttributeError instead of RuntimeError, depending in which C API call

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005194- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5195
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005196- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5197 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5198 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5199 ``printf`` function, whereas PyString_FromFormat has an independent
5200 implementation and uses "%zd" on all platforms for size_t values.
5201 This makes a difference on win64, where ``printf`` needs "%Id" to display
5202 64bit values.
5203
Benjamin Peterson97179b02008-09-09 20:55:01 +00005204- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5205 error.

5208 object; previously an int would be returned for small values. the __long__
5209 method is allowed to return either an int or a long, but the behaviour of
5210 float objects should not change to respect backward compatibility.
5211
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005212- Issue #3751: str.rpartition would perform a left-partition when called with
5213 a unicode argument.
5214
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005215- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005218 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005219 was correctly parsed but parsing of subsequent arguments failed.
5220
Vinay Sajip35e3b032008-09-01 14:33:59 +00005221- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005222 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5223 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5224 when given a tuple of classes as second argument, were looking up
5225 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5226 type object.
5227
Neal Norwitz18aa3882008-08-24 05:04:52 +00005228- Fix crashes on memory allocation failure found with failmalloc.
5229
5230- Fix memory leaks found with valgrind and update suppressions file.
5231
5232- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5233
5234- Fix problem using wrong name in decimal module reported by pychecker.

Brett Cannon672237d2008-09-09 00:49:16 +00005271 return a list or None rather than a custom object.
5272
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005273- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005297 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5298 for catch_warnings() also led to an improvement in the raising of a

5371-----------------
5372
Guido van Rossumf8402962008-08-20 15:01:50 +00005373- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5374 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5375 extensions do not automatically benefit from the class attribute
5376 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5377 to their tp_flags field if they care. This is a backwards
5378 compatibility feature; in 3.0, all types will use the cache by
5379 default.
5380
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005381- Keyword arguments can now follow starred arguments. (``f(a, *args,
5382 keyword=23)`` is now valid syntax.)
5383
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005384- ctypes function pointers that are COM methods have a boolean True
5385 value again.
5386
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005387- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5388 by denying s# to parse objects that have a releasebuffer procedure,
5389 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00005391- Issue #3537: Fix an assertion failure when an empty but presized dict
5392 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00005394- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5395 ValueError consistently across platforms.
5396
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005397- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5398 (64bit Unix, for example), unichr() would truncate its argument and return
5399 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5400
Neal Norwitze7d8be82008-07-31 17:17:14 +00005401- Apply security patches from Apple.
5402
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005403- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00005406- Issue #1819: function calls with several named parameters are now on
5407 average 35% faster (as measured by pybench).
5408
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005409- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5410 the python debugger steps into a class statement: the free variables (local
5411 variables defined in an outer scope) would be deleted from the outer scope.
5412
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005413- Issue #2620: Overflow checking when allocating or reallocating memory
5414 was not always being done properly in some python types and extension
5415 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5416 all been updated to perform better checks and places in the code that
5417 would previously leak memory on the error path when such an allocation
5418 failed have been fixed.

5424
Benjamin Petersone977ad42008-08-20 01:42:01 +00005425- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5426 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5427
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005428- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5429 version reported by these tools does not necessarily follow the python
5430 version numbering scheme, so the module is less strict when parsing it.
5431
Nick Coghlanf70385a2008-08-18 12:42:46 +00005432- Issue #2235: Added Py3k warnings for types which will become unhashable
5433 under the stricter __hash__ inheritance rules in 3.0. Several types
5434 which did not meet the rules for hash invariants and were already
5435 unhashable in 3.0 have now been explicitly flagged as unhashable in
5436 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5437 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5438
Brett Cannon88f801d2008-08-18 00:46:22 +00005439- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5440 imported into the module but exposed as part of the module's API.
5441

5447
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005448- Issue #3575: Incremental decoder's decode function now takes bytearray
5449 by using 's*' instead of 't#'.
5450
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005451- Issue #2222: Fixed reference leak when occurred os.rename()

Facundo Batistaeb90b782008-08-16 14:44:07 +00005460- Issue #2776: fixed small issue when handling an URL with double slash
5461 after a 302 response in the case of not going through a proxy.
5462
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005463- Issue #2676: in the email package, content-type parsing was hanging on
5464 pathological input because of quadratic or exponential behaviour of a
5465 regular expression.
5466
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005467- Issue #3476: binary buffered reading through the new "io" library is now
5468 thread-safe.
5469
Brett Cannonbf3157b2008-08-14 05:00:03 +00005470- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5471 since mimetools itself is deprecated. Because modules are cached, all
5472 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5473
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005474- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00005476- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5477 menu entries were not deleted.
5478
Brett Cannon83e81842008-08-09 23:30:55 +00005479- Copied the implementation of reduce() to _functools.reduce() to have a
5480 version that did not raise a DeprecationWarning under -3.
5481
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005482- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5483 a MemoryError rather than silently stop the iteration.
5484
Guido van Rossum59ce9012008-08-09 14:55:34 +00005485- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5486 to _sre.compile() will now be rejected. This should not affect anybody
5487 since the re.compile() function never generates invalid re-bytecode.
5488
Skip Montanaroa032bf42008-08-08 22:52:51 +00005489- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5490 upon first access it can be automatically initialized from the csv file if
5491 it wasn't initialized during instantiation.
5492
Brett Cannon3aa2a492008-08-06 22:28:09 +00005493- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5494 the reload() built-in has been removed.
5495
Brett Cannon7e30b672008-08-04 21:52:25 +00005496- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005497 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5505 raised an AttributeError.
5506
Benjamin Peterson01a24322008-07-28 23:35:27 +00005507- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005508 asking for a specific length. This problem only affected files opened
5509 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005510

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005534- Issue #3394: zipfile.writestr sets external attributes when passed a
5535 file name rather than a ZipInfo instance, so files are extracted with
5536 mode 0600 rather than 000 under Unix.
5537
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005538- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5539 argument in python 2.5, this broke code that subclassed Popen to include its
5540 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005550- Issue #2235: the C API function PyObject_HashNotImplemented and its
5551 interaction with the tp_hash slot (added in 2.6b2) are now documented
5552
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005553- Issue #643841: The language reference now provides more detailed
5554 coverage of the lookup process for special methods. The disclaimers
5555 regarding lack of coverage of new-style classes have also been
5556 removed, since the coverage is now fairly reasonable.

5560================================
5561
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005562*Release date: 17-Jul-2008*
5563
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005564Core and Builtins
5565-----------------
5566
Georg Brandl3e483f62008-07-16 22:57:41 +00005567- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5568 its methods now allow for items objects that can be converted to
5569 an integer using operator.index().
5570
Mark Dickinson64b7e502008-07-16 09:40:03 +00005571- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5572 produced a ValueError instead of giving the correct float.
5573
Eric Smitha5fa5a22008-07-16 00:11:49 +00005574- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5575 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5576
Mark Dickinson7103aa42008-07-15 19:08:33 +00005577- Issue #3008: the float type has a new instance method 'float.hex'
5578 and a new class method 'float.fromhex' to convert floating-point
5579 numbers to and from hexadecimal strings, respectively.
5580
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005581- Issue #2235: __hash__ is once again inherited by default. To allow
5582 collections.Hashable to remain meaningful in the presence of the
5583 default hash implementation (object.__hash__), it is now possible
5584 to explicit block inheritance of hash by setting __hash__=None at
5585 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5586 level.
5587
Nick Coghlanb028f502008-07-13 14:52:36 +00005588- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5589 the parent module cannot be found while performing an absolute import.
5590 This means that an incorrectly defined __package__ attribute will
5591 now only prevent relative imports in that module rather than causing
5592 all imports from that module to fail.
5593
Nick Coghlan14ff9942008-07-08 14:21:42 +00005594- Issue #2517: Allow unicode messages in Exceptions again by correctly
5595 bypassing the instance dictionary when looking up __unicode__ on
5596 new-style classes.
5597
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005598- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5599 set to a custom object whose write() method happens to install
5600 another file in sys.stdout.
5601
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005602- Issue #3088: Corrected a race condition in classes derived from
5603 threading.local: the first member set by a thread could be saved in
5604 another thread's dictionary.
5605
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005606- Issue #3004: Minor change to slice.indices(): the start and stop
5607 arguments are now treated identically, making the behaviour easier
5608 to describe and understand. For example, slice(None, -10,
5609 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5610 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5611 10, -1).
5612
Georg Brandl278fc502008-07-19 12:46:12 +00005613- Issue #3219: Calling a function with repeated keyword arguments,
5614 f(a=2, a=23), would not cause a syntax error. This was a regression
5615 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005616
Georg Brandl278fc502008-07-19 12:46:12 +00005617- Issue #2862: Make int and float freelist management consistent with
5618 other freelists. Changes their CompactFreeList apis into
5619 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005620

5622-------
5623
Thomas Heller57adf222008-08-14 19:10:48 +00005624- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5625 api functions without holding the GIL, which could lead to a fatal
5626 error when they failed.
5627
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005628- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005636- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5637 ForkingPickler.register() to resolve conflict with ctypes.
5638
Vinay Sajip51e65192008-07-18 09:01:10 +00005639- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005640
Thomas Heller880f5292008-07-15 19:39:38 +00005641- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5642 a valid dlerror() message.
5643
Thomas Heller2bad6572008-07-15 17:19:50 +00005644- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5645 incomplete structure was created.
5646
Brett Cannon3d0b9f02008-07-13 01:15:07 +00005647- Issue #3339: dummy_thread.acquire() should not return None.

5650
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005651- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005652
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005653- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5654 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005655 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005656 content-length. The problem had been corrected in the 2.4 branch, but never
5657 merged into trunk.
5658
Georg Brandle78fbcc2008-07-05 10:13:36 +00005659- Issue #2663: add filtering capability to shutil.copytree().

5665- Issue #1746: Correct handling of zipfile archive comments (previously
5666 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00005667 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00005668
Vinay Sajip51e65192008-07-18 09:01:10 +00005669- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005670 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005671
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005672- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5673 handling is now the same as that of other special attributes like __name__).
5674
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005675- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5676 removal in Python 3.0 in favor of urllib2.urlopen().
5677
Gregory P. Smithf4140642008-07-06 07:16:40 +00005678- Issue #2113: Fix error in subprocess.Popen if the select system call is
5679 interrupted by a signal.
5680

Georg Brandl5cc774e2008-06-11 20:28:06 +00006065 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006066
6067 This is controlled by the configure argument ``--with-universal-archs``:
6068
6069 - ``--with-universal-archs=all``: install 4-way universal
6070
6071 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6072
6073 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6074
6075 This option should be used in combination with ``--enable-universalsdk=``.
6076
6077 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 +00006127- Issue #1631171: Re-implement the 'warnings' module in C (the
6128 original Python code has been kept as backup). This will allow for
6129 using the 'warning's machinery in such places as the parser where
6130 use of pure Python code is not possible. Both the ``showarning()``
6131 and ``formatwarning()`` gain an optional 'line' argument which is
6132 not called by default for backwards-compatibility reasons. Setting
6133 ``warnings.showwarning()`` to an implementation that lacks support
6134 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006197- Issue #2550: The approach used by client/server code for obtaining
6198 ports to listen on in network-oriented tests has been refined in an
6199 effort to facilitate running multiple instances of the entire
6200 regression test suite in parallel without issue.
6201 test_support.bind_port() has been fixed such that it will always
6202 return a unique port -- which wasn't always the case with the
6203 previous implementation, especially if socket options had been set
6204 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6205 new implementation of bind_port() will actually raise an exception
6206 if it is passed an AF_INET/SOCK_STREAM socket with either the
6207 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6208 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6209 the socket it's been passed. This currently only applies to
6210 Windows. This option prevents any other sockets from binding to the
6211 host/port we've bound to, thus removing the possibility of the
6212 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6213 when a second SOCK_STREAM socket binds and accepts to a host/port
6214 that's already been bound by another socket. The optional preferred
6215 port parameter to bind_port() has been removed. Under no
6216 circumstances should tests be hard coding ports!
6217
6218 test_support.find_unused_port() has also been introduced, which will
6219 pass a temporary socket object to bind_port() in order to obtain an
6220 unused port. The temporary socket object is then closed and
6221 deleted, and the port is returned. This method should only be used
6222 for obtaining an unused port in order to pass to an external program
6223 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6224 a parameter to a server-oriented class that doesn't give you direct
6225 access to the underlying socket used.
6226
6227 Finally, test_support.HOST has been introduced, which should be used
6228 for the host argument of any relevant socket calls (i.e. bind and
6229 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006230
6231 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006232 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

6234 test_asynchat and test_socket_ssl.
6235
Georg Brandl3ee81df2008-05-17 18:14:43 +00006236 It is now possible for multiple instances of the regression test
6237 suite to run in parallel without issue.

6504-----------------
6505
Fred Drakea8ee94b2008-03-01 02:45:07 +00006506- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006507 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006508
Georg Brandlad61bc82008-02-23 15:11:18 +00006509- Issue #2067: file.__exit__() now calls subclasses' close() method.
6510
6511- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006512
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006513- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006514 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006515
Eric Smitha73fbe72008-02-23 03:09:44 +00006516- Added the future_builtins module, which contains hex() and oct().
6517 These are the PEP 3127 version of these functions, designed to be
6518 compatible with the hex() and oct() builtins from Python 3.0. They
6519 differ slightly in their output formats from the existing, unchanged
6520 Python 2.6 builtins. The expected usage of the future_builtins
6521 module is:
6522 from future_builtins import hex, oct
6523
Eric Smith7ef40bf2008-02-20 23:34:22 +00006524- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6525 exponents for exponents with absolute value < 100. Follows C99
6526 standard. This is a change on Windows, which would use 3 digits.
6527 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6528 so that any alterations it does to the resulting string will be
6529 available in stringlib/formatter.h (for float.__format__).
6530
Eric Smith5a3c1352008-02-19 13:21:56 +00006531- Implemented PEP 3101, Advanced String Formatting. This adds a new
6532 builtin format(); a format() method for str and unicode; a
6533 __format__() method to object, str, unicode, int, long, float, and
6534 datetime; the class string.Formatter; and the C API
6535 PyObject_Format().
6536
Georg Brandl3ee81df2008-05-17 18:14:43 +00006537- Fixed several potential crashes, all caused by specially crafted
6538 __del__ methods exploiting objects in temporarily inconsistent
6539 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006540
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006541- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006542 prevent a possible crash: an Abstract Base Class would try to access
6543 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006544
Georg Brandl3ee81df2008-05-17 18:14:43 +00006545- Fixed repr() and str() of complex numbers with infinity or nan as
6546 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006547
Georg Brandl3ee81df2008-05-17 18:14:43 +00006548- Clear all free lists during a gc.collect() of the highest generation
6549 in order to allow pymalloc to free more arenas. Python may give back
6550 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006551
Georg Brandl3ee81df2008-05-17 18:14:43 +00006552- Issue #2045: Fix an infinite recursion triggered when printing a
6553 subclass of collections.defaultdict, if its default_factory is set
6554 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006555
Christian Heimesf75dbef2008-02-08 00:11:31 +00006556- Fixed a minor memory leak in dictobject.c. The content of the free
6557 list was not freed on interpreter shutdown.
6558
Georg Brandl21e99f42010-03-07 15:23:59 +00006559- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006560 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006561
Georg Brandl3ee81df2008-05-17 18:14:43 +00006562- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6563 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006564 to compact the internal free lists of pre-allocted ints and floats.
6565
Georg Brandl3ee81df2008-05-17 18:14:43 +00006566- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6567 calls. Python expected the return type int but the fork familie
6568 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006569
Georg Brandl3ee81df2008-05-17 18:14:43 +00006570- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6571 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006572
Georg Brandl3ee81df2008-05-17 18:14:43 +00006573- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6574 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006575
Georg Brandl3ee81df2008-05-17 18:14:43 +00006576- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6577 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006578
Georg Brandl3ee81df2008-05-17 18:14:43 +00006579- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6580 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006581
Georg Brandl3ee81df2008-05-17 18:14:43 +00006582- Patch #1473257: generator objects gain a gi_code attribute. This is
6583 the same object as the func_code attribute of the function that
6584 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006585
Georg Brandl3ee81df2008-05-17 18:14:43 +00006586- Issue #1920: "while 0" statements were completely removed by the
6587 compiler, even in the presence of an "else" clause, which is
6588 supposed to be run when the condition is false. Now the compiler
6589 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006590
Guido van Rossumeead05f2008-01-24 18:21:02 +00006591- A few crashers fixed: weakref_in_del.py (issue #1377858);
6592 loosing_dict_ref.py (issue #1303614, test67.py);
6593 borrowed_ref_[34].py (not in tracker).
6594
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006595- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006596 suppressed while an extension is loaded by calling SetErrorMode in
6597 dynload_win.c. The error is still reported properly.
6598
Georg Brandl3ee81df2008-05-17 18:14:43 +00006599- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006600 several extension methods and modules do not work without unicode
6601 support.
6602
Georg Brandl26543b12008-01-21 18:36:51 +00006603- Issue #1882: when compiling code from a string, encoding cookies in the
6604 second line of code were not always recognized correctly.
6605
Georg Brandl14404b62008-01-19 19:27:05 +00006606- Issue #1679: "0x" was taken as a valid integer literal.
6607
Georg Brandl6caad7d2008-01-26 14:19:22 +00006608- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006609 added.
6610
Christian Heimesc94e2b52008-01-14 04:13:37 +00006611- sys.float_info / PyFloat_GetInfo: The floating point information
6612 object was converted from a dict to a specialized structseq object.
6613
Georg Brandl3ee81df2008-05-17 18:14:43 +00006614- Patch #1816: Added sys.flags structseq. It exposes the status of
6615 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006616
Georg Brandl3ee81df2008-05-17 18:14:43 +00006617- Objects/structseq.c: Implemented new structseq representation. The
6618 patch makes structseqs (e.g. the return value of os.stat) more
6619 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006620
Georg Brandl3ee81df2008-05-17 18:14:43 +00006621- Patch #1700288: added a type attribute cache that caches method
6622 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006623
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006624- Bug #1776: __import__() no longer accepts filenames on any platform.
6625 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006626
Georg Brandlaed6c662008-01-07 17:25:53 +00006627- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6628
Georg Brandl3ee81df2008-05-17 18:14:43 +00006629- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6630 envvar and sys.dont_write_bytecode attribute. All these can be set
6631 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006632
Georg Brandl3ee81df2008-05-17 18:14:43 +00006633- Improve some exception messages when Windows fails to load an
6634 extension module. Now we get for example '%1 is not a valid Win32
6635 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006636
Georg Brandl3ee81df2008-05-17 18:14:43 +00006637- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006639- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6640 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006641
Christian Heimes0a8143f2007-12-18 23:22:54 +00006642- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006643 and INF. float("nan"), float("inf") and float("-inf") now work on
6644 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006645
Georg Brandl3ee81df2008-05-17 18:14:43 +00006646- Compiler now generates simpler and faster code for dictionary
6647 literals. The oparg for BUILD_MAP now indicates an estimated
6648 dictionary size. There is a new opcode, STORE_MAP, for adding
6649 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006650
Georg Brandl3ee81df2008-05-17 18:14:43 +00006651- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006656- Issue #1538: Avoid copying string in split/rsplit if the split char
6657 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006658
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006659- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006660 SystemError.
6661
Nick Coghlanef01d822007-12-03 12:55:17 +00006662- PEP 366: Allow explicit relative imports when executing modules
6663 inside packages with the -m switch via a new module level
6664 __package__ attribute.
6665
Georg Brandl3ee81df2008-05-17 18:14:43 +00006666- Issue #1402: Fix a crash on exit, when another thread is still
6667 running, and if the deallocation of its frames somehow calls the
6668 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006669

6679 file can now be directly executed by passing their name to the
6680 interpreter. The directory/zipfile is automatically inserted as the
6681 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006682
Georg Brandl3ee81df2008-05-17 18:14:43 +00006683- Issue #1265: Fix a problem with sys.settrace, if the tracing
6684 function uses a generator expression when at the same time the
6685 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006686
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006687- sets and frozensets now have an isdisjoint() method.
6688
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006689- optimize the performance of builtin.sum().
6690
Neal Norwitz44f326e2007-10-05 05:29:17 +00006691- Fix warnings found by the new version of the Coverity checker.
6692
Georg Brandl21e99f42010-03-07 15:23:59 +00006693- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006694 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6695 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006696
Georg Brandl3ee81df2008-05-17 18:14:43 +00006697- Issue #1686386: Tuple's tp_repr did not take into account the
6698 possibility of having a self-referential tuple, which is possible
6699 from C code. Nor did object's tp_str consider that a type's tp_str
6700 could do something that could lead to an inifinite recursion.
6701 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6702 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006703
Georg Brandl3ee81df2008-05-17 18:14:43 +00006704- Issue #1164: It was possible to trigger deadlock when using the
6705 'print' statement to write to a file since the GIL was not released
6706 as needed. Now PyObject_Print() does the right thing along with
6707 various tp_print implementations of the built-in types and those in
6708 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006709
Georg Brandl3ee81df2008-05-17 18:14:43 +00006710- Issue #1147: Exceptions were directly allowing string exceptions in
6711 their throw() method even though string exceptions no longer
6712 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006713
Georg Brandl3ee81df2008-05-17 18:14:43 +00006714- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00006717- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006718 PyObject_Call() never calling back out to Python code to trigger
6719 recursion depth updates/checks. Required the creation of a static
6720 RuntimeError instance in case normalizing an exception put the
6721 recursion check value past its limit. Fixes crashers
6722 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006723
Georg Brandl3ee81df2008-05-17 18:14:43 +00006724- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006737- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006738 __*__ attributes. (Some already existed, e.g., __doc__ and
6739 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006740
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006741- Add -3 option to the interpreter to warn about features that are
6742 deprecated and will be changed/removed in Python 3.0.
6743

6745 calls.
6746
Collin Winter62903052007-05-18 23:11:24 +00006747- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006748 "except E as target:". This is to provide forwards compatibility
6749 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006750
Brett Cannon229cee22007-05-05 01:34:02 +00006751- Deprecate BaseException.message as per PEP 352.
6752
Georg Brandl3ee81df2008-05-17 18:14:43 +00006753- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006754 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006756- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006757 setting a plain string, ie don't expand to single letter identifiers.
6758
Raymond Hettinger13936692007-04-11 18:40:58 +00006759- Request #1191699: Slices can now be pickled.

6763 remaining characters.
6764
Georg Brandl5cb76c12007-03-21 09:00:39 +00006765- Patch #1682205: a TypeError while unpacking an iterable is no longer

6769
Guido van Rossum143b5642007-03-23 04:58:42 +00006770- Bug #1683368: The object.__init__() and object.__new__() methods are
6771 now stricter in rejecting excess arguments. The only time when
6772 either allows excess arguments is when it is not overridden and the
6773 other one is. For backwards compatibility, when both are
6774 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006775 warning later). Also, type.__init__() insists on the same signature
6776 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006777
Georg Brandl3ee81df2008-05-17 18:14:43 +00006778- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6779 object to complex using its __complex__() method before falling back
6780 to the __float__() method. Therefore, the functions in the cmath
6781 module now can operate on objects that define a __complex__()
6782 method.

6786 same slot names.

6799
Georg Brandl7b9c5552007-03-12 14:30:05 +00006800- Bug #1678647: write a newline after printing an exception in any
6801 case, even when converting the value to a string failed.
6802
Georg Brandl871f1bc2007-03-12 13:17:36 +00006803- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006804 its argument, if it exists. If not, it will work like before. This
6805 allows customizing the output of dir() in the presence of a
6806 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006807
Collin Winter276887b2007-03-12 16:11:39 +00006808- Patch #922167: Python no longer segfaults when faced with infinitely
6809 self-recursive reload() calls (as reported by bug #742342).
6810

6815 parthensized forms. This means complex(repr(x)) now works instead of
6816 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006817
Georg Brandlaa2321b2007-03-07 00:40:28 +00006818- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006819 makes the filenames the warning module prints much more sensible
6820 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006821

6823 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006824 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00006833- Patch #1674228: when assigning a slice (old-style), check for the
6834 sq_ass_slice instead of the sq_slice slot.
6835
Georg Brandl3ee81df2008-05-17 18:14:43 +00006836- When printing an unraisable error, don't print exceptions. before
6837 the name. This duplicates the behavior whening normally printing
6838 exceptions.

7342 work started with create_connection() and timeout in httplib, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00007371 AttributeError instead of an IOError when the server's response
7372 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007373

Georg Brandl3ee81df2008-05-17 18:14:43 +00007378- Patch #1429539: pdb now correctly initializes the __main__ module
7379 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007380 correctly now.
7381

7404
Georg Brandl92a6bae2007-03-13 17:43:32 +00007405- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007406 are set for invalid interpolation sequences that would lead to
7407 errors on reading back those values.

7461

7463 TestCase and TestSuite subclasses (not instances) are no longer
7464 accepted in TestSuite.addTest(). This should cause no
7465 incompatibility since it never made sense with ordinary subclasses
7466 -- the failure just occurred later, with a more cumbersome

Georg Brandl3ee81df2008-05-17 18:14:43 +00007748- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7749 with RFC 3207 and forgets any knowledge obtained from the server not
7750 obtained from the TLS negotiation itself. Patch contributed by Bill
7751 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007752
Georg Brandl3ee81df2008-05-17 18:14:43 +00007753- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007754 that the SMTP.starttls() caller no longer needs to call ehlo()
7755 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007756 does not claim to support starttls. Adds the
7757 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7838 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7839 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007856 time so that opening a database previously created with the DB_DUP
7857 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7858 opens. Specifically: dictionary assignment to a DB object will
7859 replace all values for a given key when the database allows
7860 duplicate values. DB users should use DB.put(k, v) when they want
7861 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007862

7868 characters with ASCII value less than 32. Also, it correctly quotes
7869 dots only if they occur on a single line, as opposed to the previous
7870 behavior of quoting dots if they are the second character of any
7871 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007872

Georg Brandl3ee81df2008-05-17 18:14:43 +00008201- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8202 to ``PyTuple_SetItem``, it can be used to populate a brand new
8203 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00008205- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008207- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8208 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8209 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008210
8211- Patch #1720595: add T_BOOL to the range of structmember types.
8212
8213- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8214 ``PyFloat_GetInfo()`` to the float API.
8215
Georg Brandl3ee81df2008-05-17 18:14:43 +00008216- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8217 of w# format code incorrectly truncated the length to an int, even
8218 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8219 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008220
Georg Brandl3ee81df2008-05-17 18:14:43 +00008221- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8222 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008223
Georg Brandl3ee81df2008-05-17 18:14:43 +00008224- PEP 3123: Provide forward compatibility with Python 3.0, while
8225 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8226 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008227
Georg Brandl3ee81df2008-05-17 18:14:43 +00008228- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8229 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008230
8231- Patch #1733960: Allow T_LONGLONG to accept ints.
8232
8233- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
8234
Christian Heimes000a0742008-01-03 22:16:32 +00008235- Added a new API function ``PyImport_ImportModuleNoBlock``.
8236
Georg Brandl6caad7d2008-01-26 14:19:22 +00008237- Bug #1637022: Prefix AST symbols with _Py_.
8238
8239- Fix some leftovers from the conversion from int to Py_ssize_t
8240 (relevant to strings and sequences of more than 2**31 items).
8241
8242- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8243 outside of pystate.c and should not be necessary.
8244
Georg Brandl3ee81df2008-05-17 18:14:43 +00008245- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8246 absolute imports. In earlier versions they might have used relative
8247 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008248
Georg Brandl3ee81df2008-05-17 18:14:43 +00008249- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8250 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008251
Georg Brandl3ee81df2008-05-17 18:14:43 +00008252- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8253 macro so it can be used as an expression.

8258
Georg Brandl3ee81df2008-05-17 18:14:43 +00008259- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8260 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8261 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8262 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008263
Georg Brandl3ee81df2008-05-17 18:14:43 +00008264- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
8265 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00008275- buildtools now raises a DeprecationWarning.
8276
Georg Brandl3ee81df2008-05-17 18:14:43 +00008277- Removed the macfs module. It had been deprecated since Python 2.5.
8278 This lead to the deprecation of macostools.touched() as it relied
8279 solely on macfs and was a no-op under OS X.
