1716 In particular, fix extension module build failures when trying to use
1717 32-bit-only installer Pythons on systems with Xcode 4 (currently
1718 OS X 10.8, 10.7, and optionally 10.6).
1719 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1720 * Since Xcode 4 removes ppc support, extension module builds now
1721 check for ppc compiler support and by default remove ppc and
1722 ppc64 archs when they are not available.
1723 * Extension module builds now revert to using system installed
1724 headers and libs (/usr and /System/Library) if the SDK used
1725 to build the interpreter is not installed or has moved.
1726 * Try to avoid building extension modules with deprecated
1727 and problematic Apple llvm-gcc compiler. If original compiler

Mark Dickinsondbbed042011-09-19 16:38:08 +01002079- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2080 int.__pow__. These overflow checks were causing int.__pow__ to produce
2081 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002082 compiler optimizing the check away. Also fix similar overflow checks
2083 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

2096 cleared by the garbage collector. This fixes a segfault when an instance
2097 and its type get caught in a reference cycle, and the instance's

Florent Xiclunac2279652012-02-12 14:49:03 +01002152- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002153 has left two versions of customize_compiler, the original in
2154 distutils.sysconfig and another copy in distutils.ccompiler, with some

2157 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01002159- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2160 Distutils-based packages with C extension modules may fail because
2161 Apple has removed gcc-4.2, the version used to build python.org
2162 64-bit/32-bit Pythons. If the user does not explicitly override
2163 the default C compiler by setting the CC environment variable,
2164 Distutils will now attempt to compile extension modules with clang
2165 if gcc-4.2 is required but not found. Also as a convenience, if
2166 the user does explicitly set CC, substitute its value as the default
2167 compiler in the Distutils LDSHARED configuration variable for OS X.
2168 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2169 SDK, neither of which are available in Xcode 4. This change does not
2170 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002420- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2421 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2422 interpreter process. This could cause failures in non-Distutils subprocesses
2423 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002424 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002425 deployment target only in the environment of each build subprocess. It is
2426 still possible to globally override the default by setting
2427 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2428 greater or equal to the default value, the value with which the interpreter
2429 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04002457- sys.setcheckinterval() now updates the current ticker count as well as
2458 updating the check interval, so if the user decreases the check interval,
2459 the ticker doesn't have to wind down to zero from the old starting point
2460 before the new interval takes effect. And if the user increases the
2461 interval, it makes sure the new limit takes effect right away rather have an
2462 early task switch before recognizing the new interval.

3443 This prevents user-created self-referencing ordered dictionaries from
3444 becoming permanently uncollectable GC garbage. The downside is that
3445 removing __del__ means that the internal doubly-linked list has to wait for
3446 GC collection rather than freeing memory immediately when the refcnt drops
3447 to zero.

3904
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003905- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3906 start byte and the continuation byte(s) are now considered invalid, instead
3907 of the number of bytes specified by the start byte.
3908 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3909 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3910 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3911 Previous versions returned a single u'\ufffd'.

3917 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003919- Issue #8748: Fix two issues with comparisons between complex and integer
3920 objects. (1) The comparison could incorrectly return True in some cases
3921 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3922 (2) The comparison raised an OverflowError for large integers, leading
3923 to unpredictable exceptions when combining integers and complex objects
3924 in sets or dicts.
3925
Mark Dickinson81336372010-05-30 12:12:25 +00003926- Issue #5211: Implicit coercion for the complex type is now completely
3927 removed. (Coercion for arithmetic operations was already removed in 2.7

Georg Brandlfee0f442010-05-22 21:26:21 +00004063- Issue #1533: Fix inconsistency in range function argument processing: any
4064 non-float non-integer argument is now converted to an integer (if possible)
4065 using its __int__ method. Previously, only small arguments were treated this
4066 way; larger arguments (those whose __int__ was outside the range of a C long)
4067 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00004075 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00004076 benefit compared to the dynamic memory allocation fallback. Patch by
4077 Charles-François Natali.

4102 messages when accessing undefined class attributes because of the cheap
4103 inheritance with the underlying socket object. The cheap inheritance has been
4104 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00004105

Georg Brandlfee0f442010-05-22 21:26:21 +00004117- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4118 operation raises multiple signals and more than one of those signals is
4119 trapped, the specification determines the order in which the signals should be
4120 handled. In many cases this order wasn't being followed, leading to the wrong
4121 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00004122

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004287
4288Core and Builtins
4289-----------------
4290
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004291- Issue #7301: Add environment variable $PYTHONWARNINGS.
4292
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004293- Issue #8329: Don't return the same lists from select.select when no fds are
4294 changed.
4295
Georg Brandlfee0f442010-05-22 21:26:21 +00004296- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004297 on 64-bit machines. The shift count for either left or right shift is
4298 permitted to be up to sys.maxsize.
4299
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004300- Ensure that tokenization of identifiers is not affected by locale.
4301
Georg Brandlfee0f442010-05-22 21:26:21 +00004302- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004303
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004304- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4305
Georg Brandlfee0f442010-05-22 21:26:21 +00004306- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4307 with a non-empty format string. This is an effort to future-proof user
4308 code. If a derived class does not currently implement __format__ but later
4309 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004310 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004311 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004312
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004313- Issue #8268: Old-style classes (not just instances) now support weak
4314 references.
4315
Georg Brandlfee0f442010-05-22 21:26:21 +00004316- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4317 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004318
Victor Stinnerc7790ed2010-03-22 12:36:28 +00004319- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00004320
Benjamin Peterson96545892010-03-21 20:21:00 +00004321- Issue #6474: Make error message from passing an inadequate number of keyword
4322 arguments to a function correct.
4323
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004324- Issue #8164: Don't allow lambda functions to have a docstring.
4325
Victor Stinner66644262010-03-10 22:30:19 +00004326- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004327 (SIGINT). If an error occurs while importing the site module, the error is
4328 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004329 module.
4330
Collin Winter001a3952010-03-18 21:54:01 +00004331- Code objects now support weak references.

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004333Library
4334-------
4335
R. David Murray661303f2010-04-13 20:57:40 +00004336- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
4337
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004338- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00004339 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4340 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004341
Benjamin Peterson76a23c12010-04-04 23:23:22 +00004342- Issue #8310: Allow dis to examine new style classes.
4343
Georg Brandlfee0f442010-05-22 21:26:21 +00004344- Issue #8257: The Decimal construct now accepts a float instance directly,
4345 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004346
4347 >>> Decimal(1.1)
4348 Decimal('1.100000000000000088817841970012523233890533447265625')
4349
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004350- collections.Counter() now supports a subtract() method.
4351
Georg Brandlfee0f442010-05-22 21:26:21 +00004352- The functools module now has a total_ordering() class decorator to simplify
4353 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004354
Georg Brandlfee0f442010-05-22 21:26:21 +00004355- The functools module also adds cmp_to_key() as a tool to transition old-style
4356 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004357
Georg Brandlfee0f442010-05-22 21:26:21 +00004358- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4359 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004360
Georg Brandlfee0f442010-05-22 21:26:21 +00004361- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4362 InvalidOperation instead of returning False. (Comparisons involving a quiet
4363 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4364 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004365
Georg Brandlfee0f442010-05-22 21:26:21 +00004366- Issue #2531: Comparison operations between floats and Decimal instances now
4367 return a result based on the numeric values of the operands; previously they
4368 returned an arbitrary result based on the relative ordering of id(float) and
4369 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004370
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004371- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004372 argument `-` which tells it to read files to compile from stdin. Each line is
4373 read on demand and the named file is compiled immediately. (Original patch by
4374 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004375
Georg Brandlfee0f442010-05-22 21:26:21 +00004376- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4377 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00004379- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4380 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004381 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004382
Georg Brandlfee0f442010-05-22 21:26:21 +00004383- Comparisons using one of <, <=, >, >= between a complex instance and a
4384 Fractions instance now raise TypeError instead of returning True/False. This
4385 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4386 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004387
Michael Foorde6410c52010-03-29 20:04:23 +00004388- Addition of ``WeakSet`` to the ``weakref`` module.

4396
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004397- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004398 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4399 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004400
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004401- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4402 deprecated.
4403
Georg Brandlfee0f442010-05-22 21:26:21 +00004404- Issue #7860: platform.uname now reports the correct 'machine' type when Python
4405 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00004406

4411 existing at the same time, causing a Unicode error when configuration code
4412 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00004413
Georg Brandlfee0f442010-05-22 21:26:21 +00004414- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
4415 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00004416
Antoine Pitroueee91cd2010-03-26 19:27:16 +00004417- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
4418 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4419 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00004420
Florent Xiclunacf82fa62010-03-21 12:27:20 +00004421- Issue #8179: Fix macpath.realpath() on a non-existing path.

4435 locale.
Matthias Klose358e7ff2010-03-15 13:42:23 +00004436
Georg Brandlfee0f442010-05-22 21:26:21 +00004437- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set

Vinay Sajipecfa08f2010-03-12 09:16:10 +00004441- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00004442 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4443 log file to compute the next rollover time. If the log file does not exist,
4444 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004445
Georg Brandlba83f822010-03-14 09:50:54 +00004446- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

4453
Georg Brandlba83f822010-03-14 09:50:54 +00004454- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4455 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4456 This is a behavior change, so email's minor version number is now bumped, to
4457 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00004458

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004485- Issue #8300: When passing a non-integer argument to struct.pack with any
4486 integer format code, struct.pack first attempts to convert the non-integer
4487 using its __index__ method. If that method is non-existent or raises
4488 TypeError it goes on to try the __int__ method, as described below.
4489
Georg Brandlba83f822010-03-14 09:50:54 +00004490- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4491 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4492 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004493 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4494 inconsistent: __int__ was used for some integer codes but not for others, and
4495 the set of integer codes for which it was used differed between native packing
4496 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004748- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4749 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4750 returning NULL. The macro now returns a statically allocated empty string

4901-----------------
4902
Georg Brandlba83f822010-03-14 09:50:54 +00004903- The ``__complex__()`` method is now looked up on the class of instances to
4904 make it consistent with other special methods.

4908
Mark Dickinson1b34d252010-01-01 17:27:30 +00004909- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004910 DeprecationWarning when passed a float argument where an integer was expected.
4911 These functions and methods now raise TypeError instead. The majority of the
4912 effects of this change are in the extension modules, but some core functions
4913 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4914 and many unicode/str methods.

4926
Georg Brandlba83f822010-03-14 09:50:54 +00004927- Issue #1811: Improve accuracy and cross-platform consistency for true division
4928 of integers: the result of a/b is now correctly rounded for ints a and b (at
4929 least on IEEE 754 platforms), and in particular does not depend on the
4930 internal representation of a long.

4938
Georg Brandlba83f822010-03-14 09:50:54 +00004939 These executables now work properly with the arch(1) command: ``arch -ppc
4940 python`` will start a universal binary version of python in PPC mode (unlike

5080 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005081

5083 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00005096- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5097 decimal string that's guaranteed to round back to x under correct rounding
5098 (with round-half-to-even rounding mode). Previously it gave a string based on
5099 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5100 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5101 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005102
Georg Brandlba83f822010-03-14 09:50:54 +00005103- Issue #7117: On almost all platforms: float-to-string and string-to-float
5104 conversions within Python are now correctly rounded. Places these conversions
5105 occur include: str for floats and complex numbers; the float and complex
5106 constructors; old-style and new-style numeric formatting; serialization and
5107 deserialization of floats and complex numbers using marshal, pickle and json;
5108 parsing of float and imaginary literals in Python code; Decimal-to-float
5109 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005110
Georg Brandlba83f822010-03-14 09:50:54 +00005111 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5112 providing correctly-rounded strtod and dtoa C functions. This code is
5113 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5114 the C compiler. There may be a small number of platforms on which correct
5115 operation of this code cannot be guaranteed, so the code is not used: notably,
5116 this applies to platforms where the C double format is not IEEE 754 binary64,
5117 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5118 and Python's configure script is unable to determine how to change the FPU
5119 precision. On these platforms conversions use the platform strtod and dtoa,
5120 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005121
Georg Brandlba83f822010-03-14 09:50:54 +00005122- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5123 uses the correctly-rounded string <-> float conversions described above (when
5124 available), and so produces correctly rounded results that will display nicely
5125 under the float repr. There are two related small changes: (1) round now
5126 accepts any class with an ``__index__()`` method for its second argument (but
5127 no longer accepts floats for the second argument), and (2) an excessively
5128 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5129 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005271
Georg Brandlba83f822010-03-14 09:50:54 +00005272 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5273 (2) parsing of strings representing infinities and nans was locale aware; and
5274 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005276- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5277 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5278 but with at least one decimal point and with a default precision
5279 of 12. Previously, the behavior the same but with a default precision of 6.
5280 This more closely matches ``str()``, and reduces surprises when adding
5281 alignment flags to the empty presentation type. This also affects the new
5282 complex.__format__ in the same way.
5283
5284- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5285 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00005347 untrackable objects are not tracked by the garbage collector. This can reduce

5356 internal representation of integers, for performance reasons. Base 2**30 is
5357 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00005460- Issue #4597: Fixed exception handling when the __exit__ function of a context
5461 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00005462

Georg Brandlba83f822010-03-14 09:50:54 +00005465- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5466 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5467 instances. On a typical machine this saves 3 bytes of memory (on average) per
5468 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005470- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
5471 interpreter to abort ("Fatal Python error: Could not reset the stack!")
5472 instead of throwing a MemoryError.
5473
Georg Brandlba83f822010-03-14 09:50:54 +00005474- Issue #3689: The list reversed iterator now supports __length_hint__ instead
5475 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00005476
Benjamin Petersonc078f922008-11-21 22:27:24 +00005477- Issue #4367: Python would segfault during compiling when the unicodedata
5478 module couldn't be imported and \N escapes were present.
5479
Georg Brandlba83f822010-03-14 09:50:54 +00005480- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5481 file objects with closefd=False. The file descriptor is still kept open but
5482 the file object behaves like a closed file. The ``FileIO`` object also got a
5483 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00005484
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005485- Issue #4348: Some bytearray methods returned that didn't cause any change to
5486 the bytearray, returned the same bytearray instead of a copy.
5487
Georg Brandlba83f822010-03-14 09:50:54 +00005488- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

5491
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00005492- Issue #4048: The parser module now correctly validates relative imports.
5493
Benjamin Petersondcee09d2008-10-31 02:16:05 +00005494- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
5495 exec statement.
5496
Georg Brandlba83f822010-03-14 09:50:54 +00005497- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
5498 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00005499
Benjamin Petersonbdca9422008-10-26 20:21:13 +00005500- Issue #4209: Enabling unicode_literals and the print_function in the same
5501 __future__ import didn't work.
5502
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005503- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005504 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005505
Georg Brandlba83f822010-03-14 09:50:54 +00005506- On windows, ``os.chdir()`` given unicode was not working if
5507 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5508 this code path is really executed because I cannot move to such directory on
5509 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005510
Georg Brandlba83f822010-03-14 09:50:54 +00005511- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5512 element is temporarily replaced with an equivalent frozenset. But the
5513 eventual KeyError would always report the empty ``frozenset()`` as the missing
5514 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00005515
Georg Brandlba83f822010-03-14 09:50:54 +00005516- Issue #4509: Various issues surrounding resize of bytearray objects to which
5517 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00005518
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00005519- Issue #4748: Lambda generators no longer return a value.

5522
Gregory P. Smithae91d092009-03-02 05:13:57 +00005523- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
5524
Georg Brandlba83f822010-03-14 09:50:54 +00005525- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
5526 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00005527
Matthias Klose91a3b9e2009-04-05 21:19:13 +00005528- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
5529 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00005530
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00005531- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
5532 returned them on 64bit platforms.
5533
Walter Dörwalded960ac2009-05-03 22:36:33 +00005534- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5535 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5536 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5537 of using the replace error handler in PyUnicode_DecodeUTF8().
5538
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005539- Issue #3739: The unicode-internal encoder now reports the number of characters
5540 consumed like any other encoder (instead of the number of bytes).
5541
Georg Brandlba83f822010-03-14 09:50:54 +00005542- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5543 allocator will be automatically disabled when running under Valgrind. This
5544 gives improved memory leak detection when running under Valgrind, while taking
5545 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00005570- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
5571 ownership when the group is not forced, because the group may be different
5572 from the user's group and inherit from its container when the test is run.

5616 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00005617 __main__.py file. This allows applications that run other Python scripts to

6715 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6716 neither __int__ nor __long__, TypeError used to be raised (with a

6914
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006915- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6916 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6917 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6918 ``printf`` function, whereas PyString_FromFormat has an independent
6919 implementation and uses "%zd" on all platforms for size_t values.
6920 This makes a difference on win64, where ``printf`` needs "%Id" to display
6921 64bit values.

6927 object; previously an int would be returned for small values. the __long__
6928 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006938 was correctly parsed but parsing of subsequent arguments failed.
6939
Vinay Sajip35e3b032008-09-01 14:33:59 +00006940- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006941 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6942 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6943 when given a tuple of classes as second argument, were looking up
6944 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6945 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00007092- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7093 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7094 extensions do not automatically benefit from the class attribute
7095 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7096 to their tp_flags field if they care. This is a backwards
7097 compatibility feature; in 3.0, all types will use the cache by
7098 default.

Mark Dickinsonb6467572008-08-04 21:30:09 +00007113- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7114 ValueError consistently across platforms.
7115
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007116- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7117 (64bit Unix, for example), unichr() would truncate its argument and return
7118 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007122- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7123 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7124
Antoine Pitrou92f82162008-07-25 22:22:08 +00007125- Issue #1819: function calls with several named parameters are now on
7126 average 35% faster (as measured by pybench).
7127
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007128- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7129 the python debugger steps into a class statement: the free variables (local
7130 variables defined in an outer scope) would be deleted from the outer scope.
7131
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007132- Issue #2620: Overflow checking when allocating or reallocating memory
7133 was not always being done properly in some python types and extension
7134 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7135 all been updated to perform better checks and places in the code that
7136 would previously leak memory on the error path when such an allocation
7137 failed have been fixed.

7143
Benjamin Petersone977ad42008-08-20 01:42:01 +00007144- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7145 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7146
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007147- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7148 version reported by these tools does not necessarily follow the python
7149 version numbering scheme, so the module is less strict when parsing it.
7150
Nick Coghlanf70385a2008-08-18 12:42:46 +00007151- Issue #2235: Added Py3k warnings for types which will become unhashable
7152 under the stricter __hash__ inheritance rules in 3.0. Several types
7153 which did not meet the rules for hash invariants and were already
7154 unhashable in 3.0 have now been explicitly flagged as unhashable in
7155 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7156 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7157
Brett Cannon88f801d2008-08-18 00:46:22 +00007158- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00007189- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7190 since mimetools itself is deprecated. Because modules are cached, all
7191 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7192
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007193- Issue #3134: shutil referenced undefined WindowsError symbol.

7202 a MemoryError rather than silently stop the iteration.
7203
Guido van Rossum59ce9012008-08-09 14:55:34 +00007204- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7205 to _sre.compile() will now be rejected. This should not affect anybody
7206 since the re.compile() function never generates invalid re-bytecode.
7207
Skip Montanaroa032bf42008-08-08 22:52:51 +00007208- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7209 upon first access it can be automatically initialized from the csv file if
7210 it wasn't initialized during instantiation.
7211
Brett Cannon3aa2a492008-08-06 22:28:09 +00007212- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7213 the reload() built-in has been removed.
7214
Brett Cannon7e30b672008-08-04 21:52:25 +00007215- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007227 asking for a specific length. This problem only affected files opened
7228 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007229

7254 file name rather than a ZipInfo instance, so files are extracted with
7255 mode 0600 rather than 000 under Unix.
7256
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007257- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7258 argument in python 2.5, this broke code that subclassed Popen to include its
7259 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007269- Issue #2235: the C API function PyObject_HashNotImplemented and its
7270 interaction with the tp_hash slot (added in 2.6b2) are now documented
7271
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007272- Issue #643841: The language reference now provides more detailed
7273 coverage of the lookup process for special methods. The disclaimers
7274 regarding lack of coverage of new-style classes have also been
7275 removed, since the coverage is now fairly reasonable.

7279================================
7280
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007281*Release date: 17-Jul-2008*
7282
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007283Core and Builtins
7284-----------------
7285
Georg Brandl3e483f62008-07-16 22:57:41 +00007286- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7287 its methods now allow for items objects that can be converted to
7288 an integer using operator.index().
7289
Mark Dickinson64b7e502008-07-16 09:40:03 +00007290- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7291 produced a ValueError instead of giving the correct float.
7292
Eric Smitha5fa5a22008-07-16 00:11:49 +00007293- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7294 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7295
Mark Dickinson7103aa42008-07-15 19:08:33 +00007296- Issue #3008: the float type has a new instance method 'float.hex'
7297 and a new class method 'float.fromhex' to convert floating-point
7298 numbers to and from hexadecimal strings, respectively.
7299
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007300- Issue #2235: __hash__ is once again inherited by default. To allow
7301 collections.Hashable to remain meaningful in the presence of the
7302 default hash implementation (object.__hash__), it is now possible
7303 to explicit block inheritance of hash by setting __hash__=None at
7304 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7305 level.
7306
Nick Coghlanb028f502008-07-13 14:52:36 +00007307- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7308 the parent module cannot be found while performing an absolute import.
7309 This means that an incorrectly defined __package__ attribute will
7310 now only prevent relative imports in that module rather than causing
7311 all imports from that module to fail.
7312
Nick Coghlan14ff9942008-07-08 14:21:42 +00007313- Issue #2517: Allow unicode messages in Exceptions again by correctly
7314 bypassing the instance dictionary when looking up __unicode__ on
7315 new-style classes.
7316
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007317- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7318 set to a custom object whose write() method happens to install
7319 another file in sys.stdout.
7320
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007321- Issue #3088: Corrected a race condition in classes derived from
7322 threading.local: the first member set by a thread could be saved in
7323 another thread's dictionary.
7324
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007325- Issue #3004: Minor change to slice.indices(): the start and stop
7326 arguments are now treated identically, making the behaviour easier
7327 to describe and understand. For example, slice(None, -10,
7328 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7329 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7330 10, -1).
7331
Georg Brandl278fc502008-07-19 12:46:12 +00007332- Issue #3219: Calling a function with repeated keyword arguments,
7333 f(a=2, a=23), would not cause a syntax error. This was a regression
7334 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007335
Georg Brandl278fc502008-07-19 12:46:12 +00007336- Issue #2862: Make int and float freelist management consistent with
7337 other freelists. Changes their CompactFreeList apis into
7338 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007339

7342
Thomas Heller57adf222008-08-14 19:10:48 +00007343- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7344 api functions without holding the GIL, which could lead to a fatal
7345 error when they failed.
7346
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007347- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7356 ForkingPickler.register() to resolve conflict with ctypes.
7357
Vinay Sajip51e65192008-07-18 09:01:10 +00007358- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00007360- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7361 a valid dlerror() message.
7362
Thomas Heller2bad6572008-07-15 17:19:50 +00007363- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7364 incomplete structure was created.
7365
Brett Cannon3d0b9f02008-07-13 01:15:07 +00007366- Issue #3339: dummy_thread.acquire() should not return None.

7369
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007370- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007371
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007372- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7373 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007374 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007375 content-length. The problem had been corrected in the 2.4 branch, but never
7376 merged into trunk.
7377
Georg Brandle78fbcc2008-07-05 10:13:36 +00007378- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007389 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00007390
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007391- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007782 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007783
7784 This is controlled by the configure argument ``--with-universal-archs``:
7785
7786 - ``--with-universal-archs=all``: install 4-way universal
7787
7788 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7789
7790 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7791
7792 This option should be used in combination with ``--enable-universalsdk=``.
7793
7794 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 +00007843- Issue #1631171: Re-implement the 'warnings' module in C (the
7844 original Python code has been kept as backup). This will allow for
7845 using the 'warning's machinery in such places as the parser where
7846 use of pure Python code is not possible. Both the ``showarning()``
7847 and ``formatwarning()`` gain an optional 'line' argument which is
7848 not called by default for backwards-compatibility reasons. Setting
7849 ``warnings.showwarning()`` to an implementation that lacks support
7850 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007913- Issue #2550: The approach used by client/server code for obtaining
7914 ports to listen on in network-oriented tests has been refined in an
7915 effort to facilitate running multiple instances of the entire
7916 regression test suite in parallel without issue.
7917 test_support.bind_port() has been fixed such that it will always
7918 return a unique port -- which wasn't always the case with the
7919 previous implementation, especially if socket options had been set
7920 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7921 new implementation of bind_port() will actually raise an exception
7922 if it is passed an AF_INET/SOCK_STREAM socket with either the
7923 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7924 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7925 the socket it's been passed. This currently only applies to
7926 Windows. This option prevents any other sockets from binding to the
7927 host/port we've bound to, thus removing the possibility of the
7928 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7929 when a second SOCK_STREAM socket binds and accepts to a host/port
7930 that's already been bound by another socket. The optional preferred
7931 port parameter to bind_port() has been removed. Under no
7932 circumstances should tests be hard coding ports!
7933
7934 test_support.find_unused_port() has also been introduced, which will
7935 pass a temporary socket object to bind_port() in order to obtain an
7936 unused port. The temporary socket object is then closed and
7937 deleted, and the port is returned. This method should only be used
7938 for obtaining an unused port in order to pass to an external program
7939 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7940 a parameter to a server-oriented class that doesn't give you direct
7941 access to the underlying socket used.
7942
7943 Finally, test_support.HOST has been introduced, which should be used
7944 for the host argument of any relevant socket calls (i.e. bind and
7945 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007946
7947 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007948 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007949 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7950 test_asynchat and test_socket_ssl.
7951
Georg Brandl3ee81df2008-05-17 18:14:43 +00007952 It is now possible for multiple instances of the regression test
7953 suite to run in parallel without issue.

8220-----------------
8221
Fred Drakea8ee94b2008-03-01 02:45:07 +00008222- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008223 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008224
Georg Brandlad61bc82008-02-23 15:11:18 +00008225- Issue #2067: file.__exit__() now calls subclasses' close() method.
8226
8227- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008228
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008229- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008230 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008231
Eric Smitha73fbe72008-02-23 03:09:44 +00008232- Added the future_builtins module, which contains hex() and oct().
8233 These are the PEP 3127 version of these functions, designed to be
8234 compatible with the hex() and oct() builtins from Python 3.0. They
8235 differ slightly in their output formats from the existing, unchanged
8236 Python 2.6 builtins. The expected usage of the future_builtins
8237 module is:
8238 from future_builtins import hex, oct
8239
Eric Smith7ef40bf2008-02-20 23:34:22 +00008240- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8241 exponents for exponents with absolute value < 100. Follows C99
8242 standard. This is a change on Windows, which would use 3 digits.
8243 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8244 so that any alterations it does to the resulting string will be
8245 available in stringlib/formatter.h (for float.__format__).
8246
Eric Smith5a3c1352008-02-19 13:21:56 +00008247- Implemented PEP 3101, Advanced String Formatting. This adds a new
8248 builtin format(); a format() method for str and unicode; a
8249 __format__() method to object, str, unicode, int, long, float, and
8250 datetime; the class string.Formatter; and the C API
8251 PyObject_Format().
8252
Georg Brandl3ee81df2008-05-17 18:14:43 +00008253- Fixed several potential crashes, all caused by specially crafted
8254 __del__ methods exploiting objects in temporarily inconsistent
8255 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008256
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008257- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008258 prevent a possible crash: an Abstract Base Class would try to access
8259 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008260
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261- Fixed repr() and str() of complex numbers with infinity or nan as
8262 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008263
Georg Brandl3ee81df2008-05-17 18:14:43 +00008264- Clear all free lists during a gc.collect() of the highest generation
8265 in order to allow pymalloc to free more arenas. Python may give back
8266 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008267
Georg Brandl3ee81df2008-05-17 18:14:43 +00008268- Issue #2045: Fix an infinite recursion triggered when printing a
8269 subclass of collections.defaultdict, if its default_factory is set
8270 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008271
Christian Heimesf75dbef2008-02-08 00:11:31 +00008272- Fixed a minor memory leak in dictobject.c. The content of the free
8273 list was not freed on interpreter shutdown.
8274
Georg Brandl21e99f42010-03-07 15:23:59 +00008275- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008276 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008277
Georg Brandl3ee81df2008-05-17 18:14:43 +00008278- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8279 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008280 to compact the internal free lists of pre-allocted ints and floats.
8281
Georg Brandl3ee81df2008-05-17 18:14:43 +00008282- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8283 calls. Python expected the return type int but the fork familie
8284 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008285
Georg Brandl3ee81df2008-05-17 18:14:43 +00008286- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8287 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008288
Georg Brandl3ee81df2008-05-17 18:14:43 +00008289- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8290 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008291
Georg Brandl3ee81df2008-05-17 18:14:43 +00008292- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8293 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008294
Georg Brandl3ee81df2008-05-17 18:14:43 +00008295- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8296 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008297
Georg Brandl3ee81df2008-05-17 18:14:43 +00008298- Patch #1473257: generator objects gain a gi_code attribute. This is
8299 the same object as the func_code attribute of the function that
8300 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008301
Georg Brandl3ee81df2008-05-17 18:14:43 +00008302- Issue #1920: "while 0" statements were completely removed by the
8303 compiler, even in the presence of an "else" clause, which is
8304 supposed to be run when the condition is false. Now the compiler
8305 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008306
Guido van Rossumeead05f2008-01-24 18:21:02 +00008307- A few crashers fixed: weakref_in_del.py (issue #1377858);
8308 loosing_dict_ref.py (issue #1303614, test67.py);
8309 borrowed_ref_[34].py (not in tracker).
8310
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008311- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008312 suppressed while an extension is loaded by calling SetErrorMode in
8313 dynload_win.c. The error is still reported properly.
8314
Georg Brandl3ee81df2008-05-17 18:14:43 +00008315- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008316 several extension methods and modules do not work without unicode
8317 support.
8318
Georg Brandl26543b12008-01-21 18:36:51 +00008319- Issue #1882: when compiling code from a string, encoding cookies in the
8320 second line of code were not always recognized correctly.
8321
Georg Brandl14404b62008-01-19 19:27:05 +00008322- Issue #1679: "0x" was taken as a valid integer literal.
8323
Georg Brandl6caad7d2008-01-26 14:19:22 +00008324- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008325 added.
8326
Christian Heimesc94e2b52008-01-14 04:13:37 +00008327- sys.float_info / PyFloat_GetInfo: The floating point information
8328 object was converted from a dict to a specialized structseq object.
8329
Georg Brandl3ee81df2008-05-17 18:14:43 +00008330- Patch #1816: Added sys.flags structseq. It exposes the status of
8331 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008332
Georg Brandl3ee81df2008-05-17 18:14:43 +00008333- Objects/structseq.c: Implemented new structseq representation. The
8334 patch makes structseqs (e.g. the return value of os.stat) more
8335 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008336
Georg Brandl3ee81df2008-05-17 18:14:43 +00008337- Patch #1700288: added a type attribute cache that caches method
8338 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008339
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008340- Bug #1776: __import__() no longer accepts filenames on any platform.
8341 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008342
Georg Brandlaed6c662008-01-07 17:25:53 +00008343- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8344
Georg Brandl3ee81df2008-05-17 18:14:43 +00008345- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8346 envvar and sys.dont_write_bytecode attribute. All these can be set
8347 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008348
Georg Brandl3ee81df2008-05-17 18:14:43 +00008349- Improve some exception messages when Windows fails to load an
8350 extension module. Now we get for example '%1 is not a valid Win32
8351 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008352
Georg Brandl3ee81df2008-05-17 18:14:43 +00008353- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008355- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8356 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008357
Christian Heimes0a8143f2007-12-18 23:22:54 +00008358- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008359 and INF. float("nan"), float("inf") and float("-inf") now work on
8360 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008361
Georg Brandl3ee81df2008-05-17 18:14:43 +00008362- Compiler now generates simpler and faster code for dictionary
8363 literals. The oparg for BUILD_MAP now indicates an estimated
8364 dictionary size. There is a new opcode, STORE_MAP, for adding
8365 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008366
Georg Brandl3ee81df2008-05-17 18:14:43 +00008367- Issue #1638: %zd configure test fails on Linux.

8377
Nick Coghlanef01d822007-12-03 12:55:17 +00008378- PEP 366: Allow explicit relative imports when executing modules
8379 inside packages with the -m switch via a new module level
8380 __package__ attribute.
8381
Georg Brandl3ee81df2008-05-17 18:14:43 +00008382- Issue #1402: Fix a crash on exit, when another thread is still
8383 running, and if the deallocation of its frames somehow calls the
8384 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008385

8395 file can now be directly executed by passing their name to the
8396 interpreter. The directory/zipfile is automatically inserted as the
8397 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008398
Georg Brandl3ee81df2008-05-17 18:14:43 +00008399- Issue #1265: Fix a problem with sys.settrace, if the tracing
8400 function uses a generator expression when at the same time the
8401 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008402
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008403- sets and frozensets now have an isdisjoint() method.
8404
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008405- optimize the performance of builtin.sum().
8406
Neal Norwitz44f326e2007-10-05 05:29:17 +00008407- Fix warnings found by the new version of the Coverity checker.
8408
Georg Brandl21e99f42010-03-07 15:23:59 +00008409- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008410 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8411 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008412
Georg Brandl3ee81df2008-05-17 18:14:43 +00008413- Issue #1686386: Tuple's tp_repr did not take into account the
8414 possibility of having a self-referential tuple, which is possible
8415 from C code. Nor did object's tp_str consider that a type's tp_str
8416 could do something that could lead to an inifinite recursion.
8417 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8418 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008419
Georg Brandl3ee81df2008-05-17 18:14:43 +00008420- Issue #1164: It was possible to trigger deadlock when using the
8421 'print' statement to write to a file since the GIL was not released
8422 as needed. Now PyObject_Print() does the right thing along with
8423 various tp_print implementations of the built-in types and those in
8424 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008425
Georg Brandl3ee81df2008-05-17 18:14:43 +00008426- Issue #1147: Exceptions were directly allowing string exceptions in
8427 their throw() method even though string exceptions no longer
8428 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008429
Georg Brandl3ee81df2008-05-17 18:14:43 +00008430- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00008433- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008434 PyObject_Call() never calling back out to Python code to trigger
8435 recursion depth updates/checks. Required the creation of a static
8436 RuntimeError instance in case normalizing an exception put the
8437 recursion check value past its limit. Fixes crashers
8438 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008439
Georg Brandl3ee81df2008-05-17 18:14:43 +00008440- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008453- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008454 __*__ attributes. (Some already existed, e.g., __doc__ and
8455 __name__.)

Georg Brandl3ee81df2008-05-17 18:14:43 +00008464 "except E as target:". This is to provide forwards compatibility
8465 with Python 3.0.

8485
Guido van Rossum143b5642007-03-23 04:58:42 +00008486- Bug #1683368: The object.__init__() and object.__new__() methods are
8487 now stricter in rejecting excess arguments. The only time when
8488 either allows excess arguments is when it is not overridden and the
8489 other one is. For backwards compatibility, when both are
8490 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008491 warning later). Also, type.__init__() insists on the same signature
8492 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008493
Georg Brandl3ee81df2008-05-17 18:14:43 +00008494- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8495 object to complex using its __complex__() method before falling back
8496 to the __float__() method. Therefore, the functions in the cmath
8497 module now can operate on objects that define a __complex__()
8498 method.

8515
Georg Brandl7b9c5552007-03-12 14:30:05 +00008516- Bug #1678647: write a newline after printing an exception in any
8517 case, even when converting the value to a string failed.
8518
Georg Brandl871f1bc2007-03-12 13:17:36 +00008519- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008520 its argument, if it exists. If not, it will work like before. This
8521 allows customizing the output of dir() in the presence of a
8522 __getattr__().

8532 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008533
Georg Brandlaa2321b2007-03-07 00:40:28 +00008534- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008535 makes the filenames the warning module prints much more sensible
8536 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008537

Georg Brandl0fca97a2007-03-05 22:28:08 +00008549- Patch #1674228: when assigning a slice (old-style), check for the
8550 sq_ass_slice instead of the sq_slice slot.
8551
Georg Brandl3ee81df2008-05-17 18:14:43 +00008552- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00009177- unittest now verifies more of its assumptions. In particular,
9178 TestCase and TestSuite subclasses (not instances) are no longer
9179 accepted in TestSuite.addTest(). This should cause no
9180 incompatibility since it never made sense with ordinary subclasses
9181 -- the failure just occurred later, with a more cumbersome
9182 exception.

9455 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009456
Georg Brandl3ee81df2008-05-17 18:14:43 +00009457- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9458 with RFC 3207 and forgets any knowledge obtained from the server not
9459 obtained from the TLS negotiation itself. Patch contributed by Bill
9460 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009461
Georg Brandl3ee81df2008-05-17 18:14:43 +00009462- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009463 that the SMTP.starttls() caller no longer needs to call ehlo()
9464 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009465 does not claim to support starttls. Adds the
9466 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9547 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9548 silently miscode subclasses of those types. Now, it raises a
9549 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009550

Georg Brandl3ee81df2008-05-17 18:14:43 +00009565 time so that opening a database previously created with the DB_DUP
9566 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9567 opens. Specifically: dictionary assignment to a DB object will
9568 replace all values for a given key when the database allows
9569 duplicate values. DB users should use DB.put(k, v) when they want
9570 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009571

9577 characters with ASCII value less than 32. Also, it correctly quotes
9578 dots only if they occur on a single line, as opposed to the previous
9579 behavior of quoting dots if they are the second character of any
9580 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009581

Georg Brandl3ee81df2008-05-17 18:14:43 +00009915- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9916 to ``PyTuple_SetItem``, it can be used to populate a brand new
9917 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009921- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9922 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9923 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009924
9925- Patch #1720595: add T_BOOL to the range of structmember types.
9926
9927- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9928 ``PyFloat_GetInfo()`` to the float API.
9929
Georg Brandl3ee81df2008-05-17 18:14:43 +00009930- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9931 of w# format code incorrectly truncated the length to an int, even
9932 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9933 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009934
Georg Brandl3ee81df2008-05-17 18:14:43 +00009935- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9936 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009938- PEP 3123: Provide forward compatibility with Python 3.0, while
9939 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9940 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009942- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9943 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009944
9945- Patch #1733960: Allow T_LONGLONG to accept ints.
9946
9947- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9948
Christian Heimes000a0742008-01-03 22:16:32 +00009949- Added a new API function ``PyImport_ImportModuleNoBlock``.

9952
9953- Fix some leftovers from the conversion from int to Py_ssize_t
9954 (relevant to strings and sequences of more than 2**31 items).
9955
9956- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9957 outside of pystate.c and should not be necessary.
9958
Georg Brandl3ee81df2008-05-17 18:14:43 +00009959- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9960 absolute imports. In earlier versions they might have used relative
9961 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009962
Georg Brandl3ee81df2008-05-17 18:14:43 +00009963- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9964 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009965
Georg Brandl3ee81df2008-05-17 18:14:43 +00009966- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009972- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9973 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9974 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9975 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009976

Georg Brandl3ee81df2008-05-17 18:14:43 +00009989- Removed the macfs module. It had been deprecated since Python 2.5.
9990 This lead to the deprecation of macostools.touched() as it relied
9991 solely on macfs and was a no-op under OS X.
