Ned Deily18fae3f2013-01-31 01:24:55 -0800899- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
900 In particular, fix extension module build failures when trying to use
901 32-bit-only installer Pythons on systems with Xcode 4 (currently
902 OS X 10.8, 10.7, and optionally 10.6).
903 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
904 * Since Xcode 4 removes ppc support, extension module builds now
905 check for ppc compiler support and by default remove ppc and
906 ppc64 archs when they are not available.
907 * Extension module builds now revert to using system installed
908 headers and libs (/usr and /System/Library) if the SDK used
909 to build the interpreter is not installed or has moved.
910 * Try to avoid building extension modules with deprecated
911 and problematic Apple llvm-gcc compiler. If original compiler
912 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001198- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1199 int.__pow__. These overflow checks were causing int.__pow__ to produce
1200 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001201 compiler optimizing the check away. Also fix similar overflow checks
1202 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1203 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01001271- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001272 has left two versions of customize_compiler, the original in
1273 distutils.sysconfig and another copy in distutils.ccompiler, with some

1276 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01001278- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1279 Distutils-based packages with C extension modules may fail because
1280 Apple has removed gcc-4.2, the version used to build python.org
1281 64-bit/32-bit Pythons. If the user does not explicitly override
1282 the default C compiler by setting the CC environment variable,
1283 Distutils will now attempt to compile extension modules with clang
1284 if gcc-4.2 is required but not found. Also as a convenience, if
1285 the user does explicitly set CC, substitute its value as the default
1286 compiler in the Distutils LDSHARED configuration variable for OS X.
1287 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1288 SDK, neither of which are available in Xcode 4. This change does not
1289 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001562- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1563 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1564 interpreter process. This could cause failures in non-Distutils subprocesses
1565 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001566 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001567 deployment target only in the environment of each build subprocess. It is
1568 still possible to globally override the default by setting
1569 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1570 greater or equal to the default value, the value with which the interpreter
1571 was built.

1598
Barry Warsawc5643282011-07-19 17:06:30 -04001599- sys.setcheckinterval() now updates the current ticker count as well as
1600 updating the check interval, so if the user decreases the check interval,
1601 the ticker doesn't have to wind down to zero from the old starting point
1602 before the new interval takes effect. And if the user increases the
1603 interval, it makes sure the new limit takes effect right away rather have an
1604 early task switch before recognizing the new interval.

2556 This prevents user-created self-referencing ordered dictionaries from
2557 becoming permanently uncollectable GC garbage. The downside is that
2558 removing __del__ means that the internal doubly-linked list has to wait for
2559 GC collection rather than freeing memory immediately when the refcnt drops
2560 to zero.

2568 to fetch the original errno, or to filter timeout errors. Now the
2569 original error is re-raised.

2589 falling into recursion.
2590
R. David Murray7c4bf552010-08-25 01:45:57 +00002591- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four

3018
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003019- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3020 start byte and the continuation byte(s) are now considered invalid, instead
3021 of the number of bytes specified by the start byte.
3022 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3023 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3024 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003033- Issue #8748: Fix two issues with comparisons between complex and integer
3034 objects. (1) The comparison could incorrectly return True in some cases
3035 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3036 (2) The comparison raised an OverflowError for large integers, leading
3037 to unpredictable exceptions when combining integers and complex objects
3038 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003040- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00003177- Issue #1533: Fix inconsistency in range function argument processing: any
3178 non-float non-integer argument is now converted to an integer (if possible)
3179 using its __int__ method. Previously, only small arguments were treated this
3180 way; larger arguments (those whose __int__ was outside the range of a C long)
3181 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00003189 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable

3217 inheritance with the underlying socket object. The cheap inheritance has been
3218 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00003231- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3232 operation raises multiple signals and more than one of those signals is
3233 trapped, the specification determines the order in which the signals should be
3234 handled. In many cases this order wasn't being followed, leading to the wrong
3235 Python exception being raised.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003405- Issue #7301: Add environment variable $PYTHONWARNINGS.
3406
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003407- Issue #8329: Don't return the same lists from select.select when no fds are
3408 changed.
3409
Georg Brandlfee0f442010-05-22 21:26:21 +00003410- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003411 on 64-bit machines. The shift count for either left or right shift is
3412 permitted to be up to sys.maxsize.
3413
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003414- Ensure that tokenization of identifiers is not affected by locale.
3415
Georg Brandlfee0f442010-05-22 21:26:21 +00003416- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003417
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003418- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3419
Georg Brandlfee0f442010-05-22 21:26:21 +00003420- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3421 with a non-empty format string. This is an effort to future-proof user
3422 code. If a derived class does not currently implement __format__ but later
3423 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003424 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003425 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003426
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003427- Issue #8268: Old-style classes (not just instances) now support weak
3428 references.
3429
Georg Brandlfee0f442010-05-22 21:26:21 +00003430- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
3431 is set.

3439
Victor Stinner66644262010-03-10 22:30:19 +00003440- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003441 (SIGINT). If an error occurs while importing the site module, the error is
3442 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003443 module.

3451
Antoine Pitrouf9de5342010-04-05 21:35:07 +00003452- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00003453 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
3454 `ssl.OPENSSL_VERSION_NUMBER`.

3457
Georg Brandlfee0f442010-05-22 21:26:21 +00003458- Issue #8257: The Decimal construct now accepts a float instance directly,
3459 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003460
3461 >>> Decimal(1.1)
3462 Decimal('1.100000000000000088817841970012523233890533447265625')
3463
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003464- collections.Counter() now supports a subtract() method.
3465
Georg Brandlfee0f442010-05-22 21:26:21 +00003466- The functools module now has a total_ordering() class decorator to simplify
3467 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003468
Georg Brandlfee0f442010-05-22 21:26:21 +00003469- The functools module also adds cmp_to_key() as a tool to transition old-style
3470 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003471
Georg Brandlfee0f442010-05-22 21:26:21 +00003472- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3473 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003474
Georg Brandlfee0f442010-05-22 21:26:21 +00003475- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3476 InvalidOperation instead of returning False. (Comparisons involving a quiet
3477 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3478 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003479
Georg Brandlfee0f442010-05-22 21:26:21 +00003480- Issue #2531: Comparison operations between floats and Decimal instances now
3481 return a result based on the numeric values of the operands; previously they
3482 returned an arbitrary result based on the relative ordering of id(float) and
3483 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003484
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003485- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003486 argument `-` which tells it to read files to compile from stdin. Each line is
3487 read on demand and the named file is compiled immediately. (Original patch by
3488 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003489
Georg Brandlfee0f442010-05-22 21:26:21 +00003490- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
3491 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00003493- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3494 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003495 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003496
Georg Brandlfee0f442010-05-22 21:26:21 +00003497- Comparisons using one of <, <=, >, >= between a complex instance and a
3498 Fractions instance now raise TypeError instead of returning True/False. This
3499 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3500 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003501

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003511- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003512 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3513 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003514
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003515- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3516 deprecated.
3517
Georg Brandlfee0f442010-05-22 21:26:21 +00003518- Issue #7860: platform.uname now reports the correct 'machine' type when Python
3519 is running in WOW64 mode on 64 bit Windows.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003555- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003556 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3557 log file to compute the next rollover time. If the log file does not exist,
3558 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003559

Georg Brandlba83f822010-03-14 09:50:54 +00003568- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3569 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3570 This is a behavior change, so email's minor version number is now bumped, to
3571 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003599- Issue #8300: When passing a non-integer argument to struct.pack with any
3600 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00003604- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3605 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3606 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003607 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3608 inconsistent: __int__ was used for some integer codes but not for others, and
3609 the set of integer codes for which it was used differed between native packing
3610 and standard packing.)

4014Core and Builtins
4015-----------------
4016
Georg Brandlba83f822010-03-14 09:50:54 +00004017- The ``__complex__()`` method is now looked up on the class of instances to
4018 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004020- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4021 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4022
Mark Dickinson1b34d252010-01-01 17:27:30 +00004023- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004024 DeprecationWarning when passed a float argument where an integer was expected.
4025 These functions and methods now raise TypeError instead. The majority of the
4026 effects of this change are in the extension modules, but some core functions
4027 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4028 and many unicode/str methods.

4039 used to drop the time part of the result.
4040
Georg Brandlba83f822010-03-14 09:50:54 +00004041- Issue #1811: Improve accuracy and cross-platform consistency for true division
4042 of integers: the result of a/b is now correctly rounded for ints a and b (at
4043 least on IEEE 754 platforms), and in particular does not depend on the
4044 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004045

4052
Georg Brandlba83f822010-03-14 09:50:54 +00004053 These executables now work properly with the arch(1) command: ``arch -ppc
4054 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00004211- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4212 decimal string that's guaranteed to round back to x under correct rounding
4213 (with round-half-to-even rounding mode). Previously it gave a string based on
4214 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4215 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4216 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004217
Georg Brandlba83f822010-03-14 09:50:54 +00004218- Issue #7117: On almost all platforms: float-to-string and string-to-float
4219 conversions within Python are now correctly rounded. Places these conversions
4220 occur include: str for floats and complex numbers; the float and complex
4221 constructors; old-style and new-style numeric formatting; serialization and
4222 deserialization of floats and complex numbers using marshal, pickle and json;
4223 parsing of float and imaginary literals in Python code; Decimal-to-float
4224 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004225
Georg Brandlba83f822010-03-14 09:50:54 +00004226 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4227 providing correctly-rounded strtod and dtoa C functions. This code is
4228 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4229 the C compiler. There may be a small number of platforms on which correct
4230 operation of this code cannot be guaranteed, so the code is not used: notably,
4231 this applies to platforms where the C double format is not IEEE 754 binary64,
4232 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4233 and Python's configure script is unable to determine how to change the FPU
4234 precision. On these platforms conversions use the platform strtod and dtoa,
4235 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004237- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4238 uses the correctly-rounded string <-> float conversions described above (when
4239 available), and so produces correctly rounded results that will display nicely
4240 under the float repr. There are two related small changes: (1) round now
4241 accepts any class with an ``__index__()`` method for its second argument (but
4242 no longer accepts floats for the second argument), and (2) an excessively
4243 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4244 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004386
Georg Brandlba83f822010-03-14 09:50:54 +00004387 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4388 (2) parsing of strings representing infinities and nans was locale aware; and
4389 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00004390
Georg Brandlba83f822010-03-14 09:50:54 +00004391- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4392 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4393 but with at least one decimal point and with a default precision
4394 of 12. Previously, the behavior the same but with a default precision of 6.
4395 This more closely matches ``str()``, and reduces surprises when adding
4396 alignment flags to the empty presentation type. This also affects the new
4397 complex.__format__ in the same way.
4398
4399- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4400 classtype's, even if it was None. property now inserts the __doc__ into the
4401 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00004461- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00004462 untrackable objects are not tracked by the garbage collector. This can reduce
4463 the size of collections and therefore the garbage collection overhead on

4471 internal representation of integers, for performance reasons. Base 2**30 is
4472 enabled by default on 64-bit machines. Add --enable-big-digits option to
4473 configure, which overrides the default. Add sys.long_info structseq to
4474 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00004575- Issue #4597: Fixed exception handling when the __exit__ function of a context
4576 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00004577
Georg Brandlba83f822010-03-14 09:50:54 +00004578- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00004579
Georg Brandlba83f822010-03-14 09:50:54 +00004580- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4581 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4582 instances. On a typical machine this saves 3 bytes of memory (on average) per
4583 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00004584
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004585- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4586 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4587 instead of throwing a MemoryError.
4588
Georg Brandlba83f822010-03-14 09:50:54 +00004589- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4590 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00004591
Benjamin Petersonc078f922008-11-21 22:27:24 +00004592- Issue #4367: Python would segfault during compiling when the unicodedata
4593 module couldn't be imported and \N escapes were present.
4594
Georg Brandlba83f822010-03-14 09:50:54 +00004595- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4596 file objects with closefd=False. The file descriptor is still kept open but
4597 the file object behaves like a closed file. The ``FileIO`` object also got a
4598 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00004599
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004600- Issue #4348: Some bytearray methods returned that didn't cause any change to
4601 the bytearray, returned the same bytearray instead of a copy.
4602
Georg Brandlba83f822010-03-14 09:50:54 +00004603- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00004604
Benjamin Peterson273c2332008-11-17 22:39:09 +00004605- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
4606
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00004607- Issue #4048: The parser module now correctly validates relative imports.
4608
Benjamin Petersondcee09d2008-10-31 02:16:05 +00004609- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
4610 exec statement.
4611
Georg Brandlba83f822010-03-14 09:50:54 +00004612- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
4613 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00004614
Benjamin Petersonbdca9422008-10-26 20:21:13 +00004615- Issue #4209: Enabling unicode_literals and the print_function in the same
4616 __future__ import didn't work.
4617
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004618- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004619 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004620
Georg Brandlba83f822010-03-14 09:50:54 +00004621- On windows, ``os.chdir()`` given unicode was not working if
4622 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4623 this code path is really executed because I cannot move to such directory on
4624 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004625
Georg Brandlba83f822010-03-14 09:50:54 +00004626- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4627 element is temporarily replaced with an equivalent frozenset. But the
4628 eventual KeyError would always report the empty ``frozenset()`` as the missing
4629 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00004630
Georg Brandlba83f822010-03-14 09:50:54 +00004631- Issue #4509: Various issues surrounding resize of bytearray objects to which
4632 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00004633
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00004634- Issue #4748: Lambda generators no longer return a value.
4635
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00004636- Issue #3582: Use native TLS functions on Windows
4637
Gregory P. Smithae91d092009-03-02 05:13:57 +00004638- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
4639
Georg Brandlba83f822010-03-14 09:50:54 +00004640- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
4641 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00004642
Matthias Klose91a3b9e2009-04-05 21:19:13 +00004643- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
4644 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00004645
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00004646- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
4647 returned them on 64bit platforms.
4648
Walter Dörwalded960ac2009-05-03 22:36:33 +00004649- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4650 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4651 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4652 of using the replace error handler in PyUnicode_DecodeUTF8().
4653
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004654- Issue #3739: The unicode-internal encoder now reports the number of characters
4655 consumed like any other encoder (instead of the number of bytes).
4656
Georg Brandlba83f822010-03-14 09:50:54 +00004657- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4658 allocator will be automatically disabled when running under Valgrind. This
4659 gives improved memory leak detection when running under Valgrind, while taking
4660 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00004685- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
4686 ownership when the group is not forced, because the group may be different
4687 from the user's group and inherit from its container when the test is run.

Georg Brandlba83f822010-03-14 09:50:54 +00004729- Issue #6816: runpy now provides a run_path function that allows Python code to
4730 execute file paths that refer to source or compiled Python files as well as
4731 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00004732 __main__.py file. This allows applications that run other Python scripts to
4733 support the same flexibility as the CPython command line itself.
4734
Georg Brandlba83f822010-03-14 09:50:54 +00004735- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
4736 connection with another process, rather than looping endlessly. The default
4737 timeout is 20 seconds, which should be amply sufficient for local connections.

5827 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5828 neither __int__ nor __long__, TypeError used to be raised (with a

6026
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006027- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6028 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6029 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6030 ``printf`` function, whereas PyString_FromFormat has an independent
6031 implementation and uses "%zd" on all platforms for size_t values.
6032 This makes a difference on win64, where ``printf`` needs "%Id" to display
6033 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006035- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6039 object; previously an int would be returned for small values. the __long__
6040 method is allowed to return either an int or a long, but the behaviour of
6041 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006043- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00006049 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006050 was correctly parsed but parsing of subsequent arguments failed.
6051
Vinay Sajip35e3b032008-09-01 14:33:59 +00006052- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006053 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6054 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6055 when given a tuple of classes as second argument, were looking up
6056 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6057 type object.
6058
Neal Norwitz18aa3882008-08-24 05:04:52 +00006059- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006128 warnings.catch_warnings() along with some API cleanup. Expanding the tests

6202-----------------
6203
Guido van Rossumf8402962008-08-20 15:01:50 +00006204- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6205 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6206 extensions do not automatically benefit from the class attribute
6207 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6208 to their tp_flags field if they care. This is a backwards
6209 compatibility feature; in 3.0, all types will use the cache by
6210 default.
6211
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006212- Keyword arguments can now follow starred arguments. (``f(a, *args,
6213 keyword=23)`` is now valid syntax.)
6214
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006215- ctypes function pointers that are COM methods have a boolean True
6216 value again.

6227
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006228- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6229 (64bit Unix, for example), unichr() would truncate its argument and return
6230 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00006232- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006234- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6235 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6236
Antoine Pitrou92f82162008-07-25 22:22:08 +00006237- Issue #1819: function calls with several named parameters are now on
6238 average 35% faster (as measured by pybench).
6239
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006240- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6241 the python debugger steps into a class statement: the free variables (local
6242 variables defined in an outer scope) would be deleted from the outer scope.
6243
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006244- Issue #2620: Overflow checking when allocating or reallocating memory
6245 was not always being done properly in some python types and extension
6246 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6247 all been updated to perform better checks and places in the code that
6248 would previously leak memory on the error path when such an allocation
6249 failed have been fixed.

6255
Benjamin Petersone977ad42008-08-20 01:42:01 +00006256- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6257 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6258
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006259- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6260 version reported by these tools does not necessarily follow the python
6261 version numbering scheme, so the module is less strict when parsing it.
6262
Nick Coghlanf70385a2008-08-18 12:42:46 +00006263- Issue #2235: Added Py3k warnings for types which will become unhashable
6264 under the stricter __hash__ inheritance rules in 3.0. Several types
6265 which did not meet the rules for hash invariants and were already
6266 unhashable in 3.0 have now been explicitly flagged as unhashable in
6267 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6268 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6269
Brett Cannon88f801d2008-08-18 00:46:22 +00006270- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6271 imported into the module but exposed as part of the module's API.
6272

6293
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006294- Issue #2676: in the email package, content-type parsing was hanging on
6295 pathological input because of quadratic or exponential behaviour of a
6296 regular expression.
6297
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006298- Issue #3476: binary buffered reading through the new "io" library is now
6299 thread-safe.
6300
Brett Cannonbf3157b2008-08-14 05:00:03 +00006301- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6302 since mimetools itself is deprecated. Because modules are cached, all
6303 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6304

6308 menu entries were not deleted.
6309
Brett Cannon83e81842008-08-09 23:30:55 +00006310- Copied the implementation of reduce() to _functools.reduce() to have a

6312
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006313- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6314 a MemoryError rather than silently stop the iteration.
6315
Guido van Rossum59ce9012008-08-09 14:55:34 +00006316- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6317 to _sre.compile() will now be rejected. This should not affect anybody
6318 since the re.compile() function never generates invalid re-bytecode.
6319
Skip Montanaroa032bf42008-08-08 22:52:51 +00006320- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6321 upon first access it can be automatically initialized from the csv file if
6322 it wasn't initialized during instantiation.
6323
Brett Cannon3aa2a492008-08-06 22:28:09 +00006324- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6325 the reload() built-in has been removed.
6326
Brett Cannon7e30b672008-08-04 21:52:25 +00006327- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006328 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6336 raised an AttributeError.
6337

Antoine Pitroude781a42008-08-09 12:43:23 +00006339 asking for a specific length. This problem only affected files opened
6340 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006365- Issue #3394: zipfile.writestr sets external attributes when passed a
6366 file name rather than a ZipInfo instance, so files are extracted with
6367 mode 0600 rather than 000 under Unix.
6368
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006369- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6370 argument in python 2.5, this broke code that subclassed Popen to include its

6382 interaction with the tp_hash slot (added in 2.6b2) are now documented
6383
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006384- Issue #643841: The language reference now provides more detailed
6385 coverage of the lookup process for special methods. The disclaimers
6386 regarding lack of coverage of new-style classes have also been
6387 removed, since the coverage is now fairly reasonable.

6391================================
6392
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006393*Release date: 17-Jul-2008*
6394
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006395Core and Builtins
6396-----------------
6397
Georg Brandl3e483f62008-07-16 22:57:41 +00006398- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6399 its methods now allow for items objects that can be converted to
6400 an integer using operator.index().
6401
Mark Dickinson64b7e502008-07-16 09:40:03 +00006402- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6403 produced a ValueError instead of giving the correct float.
6404
Eric Smitha5fa5a22008-07-16 00:11:49 +00006405- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6406 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6407
Mark Dickinson7103aa42008-07-15 19:08:33 +00006408- Issue #3008: the float type has a new instance method 'float.hex'
6409 and a new class method 'float.fromhex' to convert floating-point
6410 numbers to and from hexadecimal strings, respectively.
6411
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006412- Issue #2235: __hash__ is once again inherited by default. To allow
6413 collections.Hashable to remain meaningful in the presence of the
6414 default hash implementation (object.__hash__), it is now possible
6415 to explicit block inheritance of hash by setting __hash__=None at
6416 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6417 level.
6418
Nick Coghlanb028f502008-07-13 14:52:36 +00006419- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6420 the parent module cannot be found while performing an absolute import.
6421 This means that an incorrectly defined __package__ attribute will
6422 now only prevent relative imports in that module rather than causing
6423 all imports from that module to fail.
6424
Nick Coghlan14ff9942008-07-08 14:21:42 +00006425- Issue #2517: Allow unicode messages in Exceptions again by correctly
6426 bypassing the instance dictionary when looking up __unicode__ on
6427 new-style classes.
6428
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006429- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6430 set to a custom object whose write() method happens to install
6431 another file in sys.stdout.
6432
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006433- Issue #3088: Corrected a race condition in classes derived from
6434 threading.local: the first member set by a thread could be saved in
6435 another thread's dictionary.
6436
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006437- Issue #3004: Minor change to slice.indices(): the start and stop
6438 arguments are now treated identically, making the behaviour easier
6439 to describe and understand. For example, slice(None, -10,
6440 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6441 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6442 10, -1).
6443
Georg Brandl278fc502008-07-19 12:46:12 +00006444- Issue #3219: Calling a function with repeated keyword arguments,
6445 f(a=2, a=23), would not cause a syntax error. This was a regression
6446 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006447
Georg Brandl278fc502008-07-19 12:46:12 +00006448- Issue #2862: Make int and float freelist management consistent with
6449 other freelists. Changes their CompactFreeList apis into
6450 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006451

6454
Thomas Heller57adf222008-08-14 19:10:48 +00006455- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6456 api functions without holding the GIL, which could lead to a fatal
6457 error when they failed.
6458
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006459- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00006467- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6468 ForkingPickler.register() to resolve conflict with ctypes.
6469
Vinay Sajip51e65192008-07-18 09:01:10 +00006470- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006471
Thomas Heller880f5292008-07-15 19:39:38 +00006472- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6473 a valid dlerror() message.
6474
Thomas Heller2bad6572008-07-15 17:19:50 +00006475- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6476 incomplete structure was created.
6477

6481
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006482- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006483
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006484- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6485 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006486 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006487 content-length. The problem had been corrected in the 2.4 branch, but never
6488 merged into trunk.
6489
Georg Brandle78fbcc2008-07-05 10:13:36 +00006490- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006501 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006502
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006503- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6504 handling is now the same as that of other special attributes like __name__).
6505
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006506- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6507 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00006896 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006897
6898 This is controlled by the configure argument ``--with-universal-archs``:
6899
6900 - ``--with-universal-archs=all``: install 4-way universal
6901
6902 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6903
6904 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6905
6906 This option should be used in combination with ``--enable-universalsdk=``.
6907
6908 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 +00006958- Issue #1631171: Re-implement the 'warnings' module in C (the
6959 original Python code has been kept as backup). This will allow for
6960 using the 'warning's machinery in such places as the parser where
6961 use of pure Python code is not possible. Both the ``showarning()``
6962 and ``formatwarning()`` gain an optional 'line' argument which is
6963 not called by default for backwards-compatibility reasons. Setting
6964 ``warnings.showwarning()`` to an implementation that lacks support
6965 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007028- Issue #2550: The approach used by client/server code for obtaining
7029 ports to listen on in network-oriented tests has been refined in an
7030 effort to facilitate running multiple instances of the entire
7031 regression test suite in parallel without issue.
7032 test_support.bind_port() has been fixed such that it will always
7033 return a unique port -- which wasn't always the case with the
7034 previous implementation, especially if socket options had been set
7035 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7036 new implementation of bind_port() will actually raise an exception
7037 if it is passed an AF_INET/SOCK_STREAM socket with either the
7038 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7039 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7040 the socket it's been passed. This currently only applies to
7041 Windows. This option prevents any other sockets from binding to the
7042 host/port we've bound to, thus removing the possibility of the
7043 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7044 when a second SOCK_STREAM socket binds and accepts to a host/port
7045 that's already been bound by another socket. The optional preferred
7046 port parameter to bind_port() has been removed. Under no
7047 circumstances should tests be hard coding ports!
7048
7049 test_support.find_unused_port() has also been introduced, which will
7050 pass a temporary socket object to bind_port() in order to obtain an
7051 unused port. The temporary socket object is then closed and
7052 deleted, and the port is returned. This method should only be used
7053 for obtaining an unused port in order to pass to an external program
7054 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7055 a parameter to a server-oriented class that doesn't give you direct
7056 access to the underlying socket used.
7057
7058 Finally, test_support.HOST has been introduced, which should be used
7059 for the host argument of any relevant socket calls (i.e. bind and
7060 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007061
7062 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007063 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

7065 test_asynchat and test_socket_ssl.
7066
Georg Brandl3ee81df2008-05-17 18:14:43 +00007067 It is now possible for multiple instances of the regression test
7068 suite to run in parallel without issue.

7334Core and builtins
7335-----------------
7336
Fred Drakea8ee94b2008-03-01 02:45:07 +00007337- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007338 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007339
Georg Brandlad61bc82008-02-23 15:11:18 +00007340- Issue #2067: file.__exit__() now calls subclasses' close() method.
7341
7342- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007343
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007344- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007345 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007346
Eric Smitha73fbe72008-02-23 03:09:44 +00007347- Added the future_builtins module, which contains hex() and oct().
7348 These are the PEP 3127 version of these functions, designed to be
7349 compatible with the hex() and oct() builtins from Python 3.0. They
7350 differ slightly in their output formats from the existing, unchanged
7351 Python 2.6 builtins. The expected usage of the future_builtins
7352 module is:
7353 from future_builtins import hex, oct
7354
Eric Smith7ef40bf2008-02-20 23:34:22 +00007355- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7356 exponents for exponents with absolute value < 100. Follows C99
7357 standard. This is a change on Windows, which would use 3 digits.
7358 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7359 so that any alterations it does to the resulting string will be
7360 available in stringlib/formatter.h (for float.__format__).
7361
Eric Smith5a3c1352008-02-19 13:21:56 +00007362- Implemented PEP 3101, Advanced String Formatting. This adds a new
7363 builtin format(); a format() method for str and unicode; a
7364 __format__() method to object, str, unicode, int, long, float, and
7365 datetime; the class string.Formatter; and the C API
7366 PyObject_Format().
7367
Georg Brandl3ee81df2008-05-17 18:14:43 +00007368- Fixed several potential crashes, all caused by specially crafted
7369 __del__ methods exploiting objects in temporarily inconsistent
7370 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007371
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007372- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007373 prevent a possible crash: an Abstract Base Class would try to access
7374 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007375
Georg Brandl3ee81df2008-05-17 18:14:43 +00007376- Fixed repr() and str() of complex numbers with infinity or nan as
7377 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007378
Georg Brandl3ee81df2008-05-17 18:14:43 +00007379- Clear all free lists during a gc.collect() of the highest generation
7380 in order to allow pymalloc to free more arenas. Python may give back
7381 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007382
Georg Brandl3ee81df2008-05-17 18:14:43 +00007383- Issue #2045: Fix an infinite recursion triggered when printing a
7384 subclass of collections.defaultdict, if its default_factory is set
7385 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007386
Christian Heimesf75dbef2008-02-08 00:11:31 +00007387- Fixed a minor memory leak in dictobject.c. The content of the free
7388 list was not freed on interpreter shutdown.
7389
Georg Brandl21e99f42010-03-07 15:23:59 +00007390- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007391 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007392
Georg Brandl3ee81df2008-05-17 18:14:43 +00007393- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7394 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007395 to compact the internal free lists of pre-allocted ints and floats.
7396
Georg Brandl3ee81df2008-05-17 18:14:43 +00007397- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7398 calls. Python expected the return type int but the fork familie
7399 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007400
Georg Brandl3ee81df2008-05-17 18:14:43 +00007401- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7402 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007403
Georg Brandl3ee81df2008-05-17 18:14:43 +00007404- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7405 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007406
Georg Brandl3ee81df2008-05-17 18:14:43 +00007407- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7408 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007409
Georg Brandl3ee81df2008-05-17 18:14:43 +00007410- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7411 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007412
Georg Brandl3ee81df2008-05-17 18:14:43 +00007413- Patch #1473257: generator objects gain a gi_code attribute. This is
7414 the same object as the func_code attribute of the function that
7415 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007416
Georg Brandl3ee81df2008-05-17 18:14:43 +00007417- Issue #1920: "while 0" statements were completely removed by the
7418 compiler, even in the presence of an "else" clause, which is
7419 supposed to be run when the condition is false. Now the compiler
7420 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007421
Guido van Rossumeead05f2008-01-24 18:21:02 +00007422- A few crashers fixed: weakref_in_del.py (issue #1377858);
7423 loosing_dict_ref.py (issue #1303614, test67.py);
7424 borrowed_ref_[34].py (not in tracker).
7425
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007426- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007427 suppressed while an extension is loaded by calling SetErrorMode in
7428 dynload_win.c. The error is still reported properly.
7429
Georg Brandl3ee81df2008-05-17 18:14:43 +00007430- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007431 several extension methods and modules do not work without unicode
7432 support.
7433
Georg Brandl26543b12008-01-21 18:36:51 +00007434- Issue #1882: when compiling code from a string, encoding cookies in the
7435 second line of code were not always recognized correctly.
7436
Georg Brandl14404b62008-01-19 19:27:05 +00007437- Issue #1679: "0x" was taken as a valid integer literal.
7438
Georg Brandl6caad7d2008-01-26 14:19:22 +00007439- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007440 added.
7441
Christian Heimesc94e2b52008-01-14 04:13:37 +00007442- sys.float_info / PyFloat_GetInfo: The floating point information
7443 object was converted from a dict to a specialized structseq object.
7444
Georg Brandl3ee81df2008-05-17 18:14:43 +00007445- Patch #1816: Added sys.flags structseq. It exposes the status of
7446 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007447
Georg Brandl3ee81df2008-05-17 18:14:43 +00007448- Objects/structseq.c: Implemented new structseq representation. The
7449 patch makes structseqs (e.g. the return value of os.stat) more
7450 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007451
Georg Brandl3ee81df2008-05-17 18:14:43 +00007452- Patch #1700288: added a type attribute cache that caches method
7453 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007454
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007455- Bug #1776: __import__() no longer accepts filenames on any platform.
7456 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007457
Georg Brandlaed6c662008-01-07 17:25:53 +00007458- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7459
Georg Brandl3ee81df2008-05-17 18:14:43 +00007460- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7461 envvar and sys.dont_write_bytecode attribute. All these can be set
7462 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007463
Georg Brandl3ee81df2008-05-17 18:14:43 +00007464- Improve some exception messages when Windows fails to load an
7465 extension module. Now we get for example '%1 is not a valid Win32
7466 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007467
Georg Brandl3ee81df2008-05-17 18:14:43 +00007468- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007470- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7471 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007472
Christian Heimes0a8143f2007-12-18 23:22:54 +00007473- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007474 and INF. float("nan"), float("inf") and float("-inf") now work on
7475 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007476
Georg Brandl3ee81df2008-05-17 18:14:43 +00007477- Compiler now generates simpler and faster code for dictionary
7478 literals. The oparg for BUILD_MAP now indicates an estimated
7479 dictionary size. There is a new opcode, STORE_MAP, for adding
7480 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007481
Georg Brandl3ee81df2008-05-17 18:14:43 +00007482- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007487- Issue #1538: Avoid copying string in split/rsplit if the split char
7488 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007489
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007490- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007491 SystemError.
7492
Nick Coghlanef01d822007-12-03 12:55:17 +00007493- PEP 366: Allow explicit relative imports when executing modules
7494 inside packages with the -m switch via a new module level
7495 __package__ attribute.
7496
Georg Brandl3ee81df2008-05-17 18:14:43 +00007497- Issue #1402: Fix a crash on exit, when another thread is still
7498 running, and if the deallocation of its frames somehow calls the
7499 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007500

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007504 attribute of an empty cell object.
7505
Georg Brandl3ee81df2008-05-17 18:14:43 +00007506- Issue #1460: The utf-7 incremental decoder did not accept truncated
7507 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007508
Georg Brandl3ee81df2008-05-17 18:14:43 +00007509- Patch #1739468: Directories and zipfiles containing a __main__.py
7510 file can now be directly executed by passing their name to the
7511 interpreter. The directory/zipfile is automatically inserted as the
7512 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007513
Georg Brandl3ee81df2008-05-17 18:14:43 +00007514- Issue #1265: Fix a problem with sys.settrace, if the tracing
7515 function uses a generator expression when at the same time the
7516 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007517
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007518- sets and frozensets now have an isdisjoint() method.
7519
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007520- optimize the performance of builtin.sum().
7521
Neal Norwitz44f326e2007-10-05 05:29:17 +00007522- Fix warnings found by the new version of the Coverity checker.
7523
Georg Brandl21e99f42010-03-07 15:23:59 +00007524- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007525 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7526 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007527
Georg Brandl3ee81df2008-05-17 18:14:43 +00007528- Issue #1686386: Tuple's tp_repr did not take into account the
7529 possibility of having a self-referential tuple, which is possible
7530 from C code. Nor did object's tp_str consider that a type's tp_str
7531 could do something that could lead to an inifinite recursion.
7532 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7533 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007534
Georg Brandl3ee81df2008-05-17 18:14:43 +00007535- Issue #1164: It was possible to trigger deadlock when using the
7536 'print' statement to write to a file since the GIL was not released
7537 as needed. Now PyObject_Print() does the right thing along with
7538 various tp_print implementations of the built-in types and those in
7539 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007540
Georg Brandl3ee81df2008-05-17 18:14:43 +00007541- Issue #1147: Exceptions were directly allowing string exceptions in
7542 their throw() method even though string exceptions no longer
7543 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007544
Georg Brandl3ee81df2008-05-17 18:14:43 +00007545- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00007548- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007549 PyObject_Call() never calling back out to Python code to trigger
7550 recursion depth updates/checks. Required the creation of a static
7551 RuntimeError instance in case normalizing an exception put the
7552 recursion check value past its limit. Fixes crashers
7553 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007554
Georg Brandl3ee81df2008-05-17 18:14:43 +00007555- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007568- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007569 __*__ attributes. (Some already existed, e.g., __doc__ and
7570 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007571
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007572- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00007579 "except E as target:". This is to provide forwards compatibility
7580 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00007582- Deprecate BaseException.message as per PEP 352.

7600
Guido van Rossum143b5642007-03-23 04:58:42 +00007601- Bug #1683368: The object.__init__() and object.__new__() methods are
7602 now stricter in rejecting excess arguments. The only time when
7603 either allows excess arguments is when it is not overridden and the
7604 other one is. For backwards compatibility, when both are
7605 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007606 warning later). Also, type.__init__() insists on the same signature
7607 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007609- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7610 object to complex using its __complex__() method before falling back
7611 to the __float__() method. Therefore, the functions in the cmath
7612 module now can operate on objects that define a __complex__()
7613 method.

7630
Georg Brandl7b9c5552007-03-12 14:30:05 +00007631- Bug #1678647: write a newline after printing an exception in any
7632 case, even when converting the value to a string failed.
7633
Georg Brandl871f1bc2007-03-12 13:17:36 +00007634- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007635 its argument, if it exists. If not, it will work like before. This
7636 allows customizing the output of dir() in the presence of a
7637 __getattr__().

7647 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007648
Georg Brandlaa2321b2007-03-07 00:40:28 +00007649- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007650 makes the filenames the warning module prints much more sensible
7651 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007664- Patch #1674228: when assigning a slice (old-style), check for the
7665 sq_ass_slice instead of the sq_slice slot.
7666
Georg Brandl3ee81df2008-05-17 18:14:43 +00007667- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00008202 AttributeError instead of an IOError when the server's response
8203 didn't contain a valid HTTP status line.

8294 TestCase and TestSuite subclasses (not instances) are no longer
8295 accepted in TestSuite.addTest(). This should cause no

8297 -- the failure just occurred later, with a more cumbersome

Georg Brandl3ee81df2008-05-17 18:14:43 +00008579- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8580 with RFC 3207 and forgets any knowledge obtained from the server not
8581 obtained from the TLS negotiation itself. Patch contributed by Bill
8582 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008583
Georg Brandl3ee81df2008-05-17 18:14:43 +00008584- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008585 that the SMTP.starttls() caller no longer needs to call ehlo()
8586 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008587 does not claim to support starttls. Adds the
8588 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8669 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8670 silently miscode subclasses of those types. Now, it raises a
8671 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008672

Georg Brandl3ee81df2008-05-17 18:14:43 +00008687 time so that opening a database previously created with the DB_DUP
8688 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8689 opens. Specifically: dictionary assignment to a DB object will
8690 replace all values for a given key when the database allows
8691 duplicate values. DB users should use DB.put(k, v) when they want
8692 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008693

8699 characters with ASCII value less than 32. Also, it correctly quotes
8700 dots only if they occur on a single line, as opposed to the previous
8701 behavior of quoting dots if they are the second character of any
8702 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008703

Georg Brandl3ee81df2008-05-17 18:14:43 +00009032- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9033 to ``PyTuple_SetItem``, it can be used to populate a brand new
9034 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009035
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009036- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009038- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9039 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9040 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009041
9042- Patch #1720595: add T_BOOL to the range of structmember types.
9043
9044- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9045 ``PyFloat_GetInfo()`` to the float API.
9046
Georg Brandl3ee81df2008-05-17 18:14:43 +00009047- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9048 of w# format code incorrectly truncated the length to an int, even
9049 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9050 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009051
Georg Brandl3ee81df2008-05-17 18:14:43 +00009052- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9053 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009054
Georg Brandl3ee81df2008-05-17 18:14:43 +00009055- PEP 3123: Provide forward compatibility with Python 3.0, while
9056 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9057 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009058
Georg Brandl3ee81df2008-05-17 18:14:43 +00009059- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9060 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009061
9062- Patch #1733960: Allow T_LONGLONG to accept ints.
9063
9064- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9065
Christian Heimes000a0742008-01-03 22:16:32 +00009066- Added a new API function ``PyImport_ImportModuleNoBlock``.
9067
Georg Brandl6caad7d2008-01-26 14:19:22 +00009068- Bug #1637022: Prefix AST symbols with _Py_.
9069
9070- Fix some leftovers from the conversion from int to Py_ssize_t
9071 (relevant to strings and sequences of more than 2**31 items).
9072
9073- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9074 outside of pystate.c and should not be necessary.
9075
Georg Brandl3ee81df2008-05-17 18:14:43 +00009076- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9077 absolute imports. In earlier versions they might have used relative
9078 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009079
Georg Brandl3ee81df2008-05-17 18:14:43 +00009080- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9081 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009082
Georg Brandl3ee81df2008-05-17 18:14:43 +00009083- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
9084 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009090- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9091 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9092 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9093 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009094
Georg Brandl3ee81df2008-05-17 18:14:43 +00009095- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00009106- buildtools now raises a DeprecationWarning.
9107
Georg Brandl3ee81df2008-05-17 18:14:43 +00009108- Removed the macfs module. It had been deprecated since Python 2.5.
9109 This lead to the deprecation of macostools.touched() as it relied
9110 solely on macfs and was a no-op under OS X.
