1726 * Since Xcode 4 removes ppc support, extension module builds now
1727 check for ppc compiler support and by default remove ppc and
1728 ppc64 archs when they are not available.
1729 * Extension module builds now revert to using system installed
1730 headers and libs (/usr and /System/Library) if the SDK used
1731 to build the interpreter is not installed or has moved.
1732 * Try to avoid building extension modules with deprecated
1733 and problematic Apple llvm-gcc compiler. If original compiler
1734 is not available, use clang instead by default.

2071
Mark Hammond323b5da2011-10-17 11:05:36 +11002072- Issue #7833: Extension modules built using distutils on Windows will no
2073 longer include a "manifest" to prevent them failing at import time in some
2074 embedded situations.
2075
Benjamin Petersona7b09762011-10-15 13:43:21 -04002076- Issue #13186: Fix __delitem__ on old-style instances when invoked through

2084
Mark Dickinsondbbed042011-09-19 16:38:08 +01002085- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2086 int.__pow__. These overflow checks were causing int.__pow__ to produce
2087 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002088 compiler optimizing the check away. Also fix similar overflow checks
2089 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2090 bugs caused test failures with recent versions of Clang.

2099 non-exception class.
Benjamin Petersonc3349cd2011-07-15 14:15:40 -05002100
Antoine Pitrou16166452011-07-12 22:04:20 +02002101- Issue #12149: Update the method cache after a type's dictionnary gets
2102 cleared by the garbage collector. This fixes a segfault when an instance
2103 and its type get caught in a reference cycle, and the instance's
2104 deallocator calls one of the methods on the type (e.g. when subclassing
2105 IOBase). Diagnosis and patch by Davide Rizzo.
2106
Florent Xiclunaa1f948b2012-01-24 21:05:10 +01002107- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +02002114 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
2115 raw_input() interrupted by CTRL+c.
2116
Łukasz Langa7a153902011-10-18 17:16:00 +02002117- Issue #10860: httplib now correctly handles an empty port after port
2118 delimiter in URLs.
2119
Barry Warsawc5643282011-07-19 17:06:30 -04002120- dict_proxy objects now display their contents rather than just the class

Florent Xiclunac2279652012-02-12 14:49:03 +01002158- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002159 has left two versions of customize_compiler, the original in
2160 distutils.sysconfig and another copy in distutils.ccompiler, with some
2161 parts of distutils calling one and others using the other.
2162 Complete the revert back to only having one in distutils.sysconfig as
2163 is the case in 3.x.
2164
Ned Deily0d0ea482012-02-10 12:59:06 +01002165- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2166 Distutils-based packages with C extension modules may fail because
2167 Apple has removed gcc-4.2, the version used to build python.org
2168 64-bit/32-bit Pythons. If the user does not explicitly override
2169 the default C compiler by setting the CC environment variable,
2170 Distutils will now attempt to compile extension modules with clang
2171 if gcc-4.2 is required but not found. Also as a convenience, if
2172 the user does explicitly set CC, substitute its value as the default
2173 compiler in the Distutils LDSHARED configuration variable for OS X.
2174 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2175 SDK, neither of which are available in Xcode 4. This change does not
2176 attempt to override settings to support their use with Xcode 4.)
2177

2244 raised when the wrapped raw file is non-blocking and the write would block.
2245 Previous code assumed that the raw write() would raise BlockingIOError, but

Ned Deily87e82bb2011-06-28 19:52:59 -07002426- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2427 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2428 interpreter process. This could cause failures in non-Distutils subprocesses
2429 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002430 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002431 deployment target only in the environment of each build subprocess. It is
2432 still possible to globally override the default by setting
2433 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2434 greater or equal to the default value, the value with which the interpreter
2435 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04002463- sys.setcheckinterval() now updates the current ticker count as well as
2464 updating the check interval, so if the user decreases the check interval,
2465 the ticker doesn't have to wind down to zero from the old starting point
2466 before the new interval takes effect. And if the user increases the
2467 interval, it makes sure the new limit takes effect right away rather have an
2468 early task switch before recognizing the new interval.

3449 This prevents user-created self-referencing ordered dictionaries from
3450 becoming permanently uncollectable GC garbage. The downside is that
3451 removing __del__ means that the internal doubly-linked list has to wait for
3452 GC collection rather than freeing memory immediately when the refcnt drops

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003911- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3912 start byte and the continuation byte(s) are now considered invalid, instead
3913 of the number of bytes specified by the start byte.
3914 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3915 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3916 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3917 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003925- Issue #8748: Fix two issues with comparisons between complex and integer
3926 objects. (1) The comparison could incorrectly return True in some cases
3927 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3928 (2) The comparison raised an OverflowError for large integers, leading
3929 to unpredictable exceptions when combining integers and complex objects
3930 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003932- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004069- Issue #1533: Fix inconsistency in range function argument processing: any
4070 non-float non-integer argument is now converted to an integer (if possible)
4071 using its __int__ method. Previously, only small arguments were treated this
4072 way; larger arguments (those whose __int__ was outside the range of a C long)
4073 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00004081 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00004082 benefit compared to the dynamic memory allocation fallback. Patch by

4108 messages when accessing undefined class attributes because of the cheap
4109 inheritance with the underlying socket object. The cheap inheritance has been
4110 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00004123- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4124 operation raises multiple signals and more than one of those signals is
4125 trapped, the specification determines the order in which the signals should be
4126 handled. In many cases this order wasn't being followed, leading to the wrong
4127 Python exception being raised.

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004293
4294Core and Builtins
4295-----------------
4296
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004297- Issue #7301: Add environment variable $PYTHONWARNINGS.
4298
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004299- Issue #8329: Don't return the same lists from select.select when no fds are
4300 changed.
4301
Georg Brandlfee0f442010-05-22 21:26:21 +00004302- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004303 on 64-bit machines. The shift count for either left or right shift is
4304 permitted to be up to sys.maxsize.
4305
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004306- Ensure that tokenization of identifiers is not affected by locale.
4307
Georg Brandlfee0f442010-05-22 21:26:21 +00004308- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004309
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004310- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4311
Georg Brandlfee0f442010-05-22 21:26:21 +00004312- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4313 with a non-empty format string. This is an effort to future-proof user
4314 code. If a derived class does not currently implement __format__ but later
4315 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004316 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004317 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004318
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004319- Issue #8268: Old-style classes (not just instances) now support weak
4320 references.
4321
Georg Brandlfee0f442010-05-22 21:26:21 +00004322- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4323 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004324
Victor Stinnerc7790ed2010-03-22 12:36:28 +00004325- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00004327- Issue #6474: Make error message from passing an inadequate number of keyword
4328 arguments to a function correct.
4329
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004330- Issue #8164: Don't allow lambda functions to have a docstring.
4331
Victor Stinner66644262010-03-10 22:30:19 +00004332- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004333 (SIGINT). If an error occurs while importing the site module, the error is
4334 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004335 module.
4336
Collin Winter001a3952010-03-18 21:54:01 +00004337- Code objects now support weak references.

4340-------
4341
R. David Murray661303f2010-04-13 20:57:40 +00004342- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
4343
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004344- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00004345 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4346 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004347
Benjamin Peterson76a23c12010-04-04 23:23:22 +00004348- Issue #8310: Allow dis to examine new style classes.
4349
Georg Brandlfee0f442010-05-22 21:26:21 +00004350- Issue #8257: The Decimal construct now accepts a float instance directly,
4351 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004352
4353 >>> Decimal(1.1)
4354 Decimal('1.100000000000000088817841970012523233890533447265625')
4355
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004356- collections.Counter() now supports a subtract() method.
4357
Georg Brandlfee0f442010-05-22 21:26:21 +00004358- The functools module now has a total_ordering() class decorator to simplify
4359 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004360
Georg Brandlfee0f442010-05-22 21:26:21 +00004361- The functools module also adds cmp_to_key() as a tool to transition old-style
4362 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004363
Georg Brandlfee0f442010-05-22 21:26:21 +00004364- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4365 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004366
Georg Brandlfee0f442010-05-22 21:26:21 +00004367- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4368 InvalidOperation instead of returning False. (Comparisons involving a quiet
4369 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4370 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004371
Georg Brandlfee0f442010-05-22 21:26:21 +00004372- Issue #2531: Comparison operations between floats and Decimal instances now
4373 return a result based on the numeric values of the operands; previously they
4374 returned an arbitrary result based on the relative ordering of id(float) and
4375 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004376
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004377- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004378 argument `-` which tells it to read files to compile from stdin. Each line is
4379 read on demand and the named file is compiled immediately. (Original patch by
4380 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004381
Georg Brandlfee0f442010-05-22 21:26:21 +00004382- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4383 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00004385- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4386 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004387 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004388
Georg Brandlfee0f442010-05-22 21:26:21 +00004389- Comparisons using one of <, <=, >, >= between a complex instance and a
4390 Fractions instance now raise TypeError instead of returning True/False. This
4391 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4392 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004393
Michael Foorde6410c52010-03-29 20:04:23 +00004394- Addition of ``WeakSet`` to the ``weakref`` module.

4402
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004403- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004404 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4405 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004406
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004407- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4408 deprecated.
4409
Georg Brandlfee0f442010-05-22 21:26:21 +00004410- Issue #7860: platform.uname now reports the correct 'machine' type when Python
4411 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00004412

4417 existing at the same time, causing a Unicode error when configuration code
4418 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00004419
Georg Brandlfee0f442010-05-22 21:26:21 +00004420- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
4421 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00004422
Antoine Pitroueee91cd2010-03-26 19:27:16 +00004423- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
4424 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4425 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00004426
Florent Xiclunacf82fa62010-03-21 12:27:20 +00004427- Issue #8179: Fix macpath.realpath() on a non-existing path.

Matthias Klose358e7ff2010-03-15 13:42:23 +00004442
Georg Brandlfee0f442010-05-22 21:26:21 +00004443- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set

Vinay Sajipecfa08f2010-03-12 09:16:10 +00004447- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00004448 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4449 log file to compute the next rollover time. If the log file does not exist,
4450 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004451
Georg Brandlba83f822010-03-14 09:50:54 +00004452- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00004460- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4461 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4462 This is a behavior change, so email's minor version number is now bumped, to
4463 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00004464

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004491- Issue #8300: When passing a non-integer argument to struct.pack with any
4492 integer format code, struct.pack first attempts to convert the non-integer
4493 using its __index__ method. If that method is non-existent or raises
4494 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00004496- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4497 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4498 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004499 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4500 inconsistent: __int__ was used for some integer codes but not for others, and
4501 the set of integer codes for which it was used differed between native packing
4502 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004754- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4755 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4756 returning NULL. The macro now returns a statically allocated empty string

4906Core and Builtins
4907-----------------
4908
Georg Brandlba83f822010-03-14 09:50:54 +00004909- The ``__complex__()`` method is now looked up on the class of instances to
4910 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004912- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4913 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4914
Mark Dickinson1b34d252010-01-01 17:27:30 +00004915- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004916 DeprecationWarning when passed a float argument where an integer was expected.
4917 These functions and methods now raise TypeError instead. The majority of the
4918 effects of this change are in the extension modules, but some core functions
4919 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4920 and many unicode/str methods.

4931 used to drop the time part of the result.
4932
Georg Brandlba83f822010-03-14 09:50:54 +00004933- Issue #1811: Improve accuracy and cross-platform consistency for true division
4934 of integers: the result of a/b is now correctly rounded for ints a and b (at
4935 least on IEEE 754 platforms), and in particular does not depend on the
4936 internal representation of a long.

4944
Georg Brandlba83f822010-03-14 09:50:54 +00004945 These executables now work properly with the arch(1) command: ``arch -ppc
4946 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00005102- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5103 decimal string that's guaranteed to round back to x under correct rounding
5104 (with round-half-to-even rounding mode). Previously it gave a string based on
5105 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5106 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5107 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005108
Georg Brandlba83f822010-03-14 09:50:54 +00005109- Issue #7117: On almost all platforms: float-to-string and string-to-float
5110 conversions within Python are now correctly rounded. Places these conversions
5111 occur include: str for floats and complex numbers; the float and complex
5112 constructors; old-style and new-style numeric formatting; serialization and
5113 deserialization of floats and complex numbers using marshal, pickle and json;
5114 parsing of float and imaginary literals in Python code; Decimal-to-float
5115 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005116
Georg Brandlba83f822010-03-14 09:50:54 +00005117 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5118 providing correctly-rounded strtod and dtoa C functions. This code is
5119 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5120 the C compiler. There may be a small number of platforms on which correct
5121 operation of this code cannot be guaranteed, so the code is not used: notably,
5122 this applies to platforms where the C double format is not IEEE 754 binary64,
5123 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5124 and Python's configure script is unable to determine how to change the FPU
5125 precision. On these platforms conversions use the platform strtod and dtoa,
5126 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005127
Georg Brandlba83f822010-03-14 09:50:54 +00005128- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5129 uses the correctly-rounded string <-> float conversions described above (when
5130 available), and so produces correctly rounded results that will display nicely
5131 under the float repr. There are two related small changes: (1) round now
5132 accepts any class with an ``__index__()`` method for its second argument (but
5133 no longer accepts floats for the second argument), and (2) an excessively
5134 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5135 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005229- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
5230 build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
5231 of stdint.h on that platform.
Mark Dickinson2f865b92009-06-30 15:32:30 +00005232

5239
Raymond Hettinger62641e92009-06-23 20:59:43 +00005240- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
5241 because it wasn't recognized as a sequence).
5242
Georg Brandlba83f822010-03-14 09:50:54 +00005243- Issue #6289: Encoding errors from ``compile()`` were being masked.

Georg Brandlba83f822010-03-14 09:50:54 +00005254 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +00005255
Georg Brandlba83f822010-03-14 09:50:54 +00005256- Issue #5982: staticmethod and classmethod now expose the wrapped function with
5257 ``__func__``.
Raymond Hettinger578a2282009-05-29 04:58:52 +00005258
Raymond Hettinger822b87f2009-05-29 01:46:48 +00005259- Added support for multiple context managers in the same with-statement.

5263 statement and correctly lookup the __enter__ and __exit__ special methods.
5264
Georg Brandlba83f822010-03-14 09:50:54 +00005265- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
5266 consistent with float("1e500") and interpretation of real and imaginary
5267 literals.
Mark Dickinsona4e0efa2009-05-20 18:43:07 +00005268
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +00005269- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
5270
Georg Brandlba83f822010-03-14 09:50:54 +00005271- ``__instancecheck__()`` and ``__subclasscheck__()`` are now completely ignored
5272 on classic classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +00005273
Georg Brandlba83f822010-03-14 09:50:54 +00005274- Issue #5994: The marshal module now has docstrings.
R. David Murray525cffc2009-05-13 13:07:14 +00005275
Mark Dickinsonb1d45852009-05-11 15:33:08 +00005276- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00005277
Georg Brandlba83f822010-03-14 09:50:54 +00005278 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5279 (2) parsing of strings representing infinities and nans was locale aware; and
5280 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00005281
Georg Brandlba83f822010-03-14 09:50:54 +00005282- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5283 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5284 but with at least one decimal point and with a default precision
5285 of 12. Previously, the behavior the same but with a default precision of 6.
5286 This more closely matches ``str()``, and reduces surprises when adding
5287 alignment flags to the empty presentation type. This also affects the new
5288 complex.__format__ in the same way.
5289
5290- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5291 classtype's, even if it was None. property now inserts the __doc__ into the
5292 subclass instance __dict__.
R. David Murray7ba8e1c2009-05-04 22:16:24 +00005293

Georg Brandlba83f822010-03-14 09:50:54 +00005297- Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3),
5298 '.5')`` now produces a sensible result.
Eric Smith9139cc62009-04-30 00:58:58 +00005299

5310 _PyOS_double_to_string or PyOS_double_to_string.
5311
Benjamin Peterson5083dc52009-04-25 00:41:22 +00005312- Issue #5283: Setting __class__ in __del__ caused a segfault.
5313
Georg Brandlba83f822010-03-14 09:50:54 +00005314- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves
5315 nans, infs or negative zeros.

Georg Brandlba83f822010-03-14 09:50:54 +00005323- Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no
5324 type code and we have an exponent.
Eric Smithaca19e62009-04-22 13:29:05 +00005325
Georg Brandlba83f822010-03-14 09:50:54 +00005326- Issue #3166: Make long -> float (and int -> float) conversions correctly

Antoine Pitrouf8387af2009-03-23 18:41:45 +00005352- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00005353 untrackable objects are not tracked by the garbage collector. This can reduce
5354 the size of collections and therefore the garbage collection overhead on
5355 long-running programs, depending on their particular use of datatypes.

5362 internal representation of integers, for performance reasons. Base 2**30 is
5363 enabled by default on 64-bit machines. Add --enable-big-digits option to
5364 configure, which overrides the default. Add sys.long_info structseq to
5365 provide information about the internal format.
Mark Dickinsonefc82f72009-03-20 15:51:55 +00005366
Benjamin Peterson6ffe8522009-03-18 20:52:15 +00005367- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

5472 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5473 instances. On a typical machine this saves 3 bytes of memory (on average) per

5485
Georg Brandlba83f822010-03-14 09:50:54 +00005486- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5487 file objects with closefd=False. The file descriptor is still kept open but
5488 the file object behaves like a closed file. The ``FileIO`` object also got a
5489 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005509- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005512- On windows, ``os.chdir()`` given unicode was not working if
5513 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5514 this code path is really executed because I cannot move to such directory on
5515 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005517- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5518 element is temporarily replaced with an equivalent frozenset. But the
5519 eventual KeyError would always report the empty ``frozenset()`` as the missing
5520 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005540- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5541 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5542 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5543 of using the replace error handler in PyUnicode_DecodeUTF8().
5544
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005545- Issue #3739: The unicode-internal encoder now reports the number of characters

5547
Georg Brandlba83f822010-03-14 09:50:54 +00005548- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5549 allocator will be automatically disabled when running under Valgrind. This
5550 gives improved memory leak detection when running under Valgrind, while taking
5551 advantage of pymalloc at other times.

6920
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006921- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6922 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6923 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6924 ``printf`` function, whereas PyString_FromFormat has an independent
6925 implementation and uses "%zd" on all platforms for size_t values.
6926 This makes a difference on win64, where ``printf`` needs "%Id" to display
6927 64bit values.

6933 object; previously an int would be returned for small values. the __long__
6934 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006944 was correctly parsed but parsing of subsequent arguments failed.
6945
Vinay Sajip35e3b032008-09-01 14:33:59 +00006946- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006947 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6948 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6949 when given a tuple of classes as second argument, were looking up
6950 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6951 type object.

7097
Guido van Rossumf8402962008-08-20 15:01:50 +00007098- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7099 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7100 extensions do not automatically benefit from the class attribute
7101 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7102 to their tp_flags field if they care. This is a backwards
7103 compatibility feature; in 3.0, all types will use the cache by
7104 default.
7105
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007106- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +00007119- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7120 ValueError consistently across platforms.
7121
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007122- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7123 (64bit Unix, for example), unichr() would truncate its argument and return
7124 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007128- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7129 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7130
Antoine Pitrou92f82162008-07-25 22:22:08 +00007131- Issue #1819: function calls with several named parameters are now on
7132 average 35% faster (as measured by pybench).
7133
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007134- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7135 the python debugger steps into a class statement: the free variables (local
7136 variables defined in an outer scope) would be deleted from the outer scope.
7137
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007138- Issue #2620: Overflow checking when allocating or reallocating memory
7139 was not always being done properly in some python types and extension
7140 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7141 all been updated to perform better checks and places in the code that
7142 would previously leak memory on the error path when such an allocation
7143 failed have been fixed.

7149
Benjamin Petersone977ad42008-08-20 01:42:01 +00007150- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7151 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7152
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007153- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7154 version reported by these tools does not necessarily follow the python
7155 version numbering scheme, so the module is less strict when parsing it.
7156
Nick Coghlanf70385a2008-08-18 12:42:46 +00007157- Issue #2235: Added Py3k warnings for types which will become unhashable
7158 under the stricter __hash__ inheritance rules in 3.0. Several types
7159 which did not meet the rules for hash invariants and were already
7160 unhashable in 3.0 have now been explicitly flagged as unhashable in
7161 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7162 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7163
Brett Cannon88f801d2008-08-18 00:46:22 +00007164- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00007195- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7196 since mimetools itself is deprecated. Because modules are cached, all
7197 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7198

7208 a MemoryError rather than silently stop the iteration.
7209
Guido van Rossum59ce9012008-08-09 14:55:34 +00007210- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7211 to _sre.compile() will now be rejected. This should not affect anybody
7212 since the re.compile() function never generates invalid re-bytecode.
7213
Skip Montanaroa032bf42008-08-08 22:52:51 +00007214- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7215 upon first access it can be automatically initialized from the csv file if
7216 it wasn't initialized during instantiation.
7217
Brett Cannon3aa2a492008-08-06 22:28:09 +00007218- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7219 the reload() built-in has been removed.
7220
Brett Cannon7e30b672008-08-04 21:52:25 +00007221- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007233 asking for a specific length. This problem only affected files opened
7234 using the new "io" module, not the built-in open() function.

7260 file name rather than a ZipInfo instance, so files are extracted with
7261 mode 0600 rather than 000 under Unix.
7262
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007263- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7264 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007275- Issue #2235: the C API function PyObject_HashNotImplemented and its
7276 interaction with the tp_hash slot (added in 2.6b2) are now documented
7277
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007278- Issue #643841: The language reference now provides more detailed
7279 coverage of the lookup process for special methods. The disclaimers
7280 regarding lack of coverage of new-style classes have also been
7281 removed, since the coverage is now fairly reasonable.

7285================================
7286
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007287*Release date: 17-Jul-2008*
7288
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007289Core and Builtins
7290-----------------
7291
Georg Brandl3e483f62008-07-16 22:57:41 +00007292- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7293 its methods now allow for items objects that can be converted to
7294 an integer using operator.index().
7295
Mark Dickinson64b7e502008-07-16 09:40:03 +00007296- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7297 produced a ValueError instead of giving the correct float.
7298
Eric Smitha5fa5a22008-07-16 00:11:49 +00007299- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7300 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7301
Mark Dickinson7103aa42008-07-15 19:08:33 +00007302- Issue #3008: the float type has a new instance method 'float.hex'
7303 and a new class method 'float.fromhex' to convert floating-point
7304 numbers to and from hexadecimal strings, respectively.
7305
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007306- Issue #2235: __hash__ is once again inherited by default. To allow
7307 collections.Hashable to remain meaningful in the presence of the
7308 default hash implementation (object.__hash__), it is now possible
7309 to explicit block inheritance of hash by setting __hash__=None at
7310 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7311 level.
7312
Nick Coghlanb028f502008-07-13 14:52:36 +00007313- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7314 the parent module cannot be found while performing an absolute import.
7315 This means that an incorrectly defined __package__ attribute will
7316 now only prevent relative imports in that module rather than causing
7317 all imports from that module to fail.
7318
Nick Coghlan14ff9942008-07-08 14:21:42 +00007319- Issue #2517: Allow unicode messages in Exceptions again by correctly
7320 bypassing the instance dictionary when looking up __unicode__ on
7321 new-style classes.
7322
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007323- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7324 set to a custom object whose write() method happens to install
7325 another file in sys.stdout.
7326
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007327- Issue #3088: Corrected a race condition in classes derived from
7328 threading.local: the first member set by a thread could be saved in
7329 another thread's dictionary.
7330
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007331- Issue #3004: Minor change to slice.indices(): the start and stop
7332 arguments are now treated identically, making the behaviour easier
7333 to describe and understand. For example, slice(None, -10,
7334 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7335 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7336 10, -1).
7337
Georg Brandl278fc502008-07-19 12:46:12 +00007338- Issue #3219: Calling a function with repeated keyword arguments,
7339 f(a=2, a=23), would not cause a syntax error. This was a regression
7340 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007341
Georg Brandl278fc502008-07-19 12:46:12 +00007342- Issue #2862: Make int and float freelist management consistent with
7343 other freelists. Changes their CompactFreeList apis into
7344 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007345

7347-------
7348
Thomas Heller57adf222008-08-14 19:10:48 +00007349- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7350 api functions without holding the GIL, which could lead to a fatal
7351 error when they failed.
7352
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007353- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7362 ForkingPickler.register() to resolve conflict with ctypes.
7363
Vinay Sajip51e65192008-07-18 09:01:10 +00007364- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00007366- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7367 a valid dlerror() message.
7368
Thomas Heller2bad6572008-07-15 17:19:50 +00007369- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7370 incomplete structure was created.
7371
Brett Cannon3d0b9f02008-07-13 01:15:07 +00007372- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00007374- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
7375
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007376- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007377
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007378- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7379 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007380 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007381 content-length. The problem had been corrected in the 2.4 branch, but never
7382 merged into trunk.
7383
Georg Brandle78fbcc2008-07-05 10:13:36 +00007384- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00007394- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007395 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00007396
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007397- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007788 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007789
7790 This is controlled by the configure argument ``--with-universal-archs``:
7791
7792 - ``--with-universal-archs=all``: install 4-way universal
7793
7794 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7795
7796 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7797
7798 This option should be used in combination with ``--enable-universalsdk=``.
7799
7800 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 +00007849- Issue #1631171: Re-implement the 'warnings' module in C (the
7850 original Python code has been kept as backup). This will allow for
7851 using the 'warning's machinery in such places as the parser where
7852 use of pure Python code is not possible. Both the ``showarning()``
7853 and ``formatwarning()`` gain an optional 'line' argument which is
7854 not called by default for backwards-compatibility reasons. Setting
7855 ``warnings.showwarning()`` to an implementation that lacks support
7856 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007919- Issue #2550: The approach used by client/server code for obtaining
7920 ports to listen on in network-oriented tests has been refined in an
7921 effort to facilitate running multiple instances of the entire
7922 regression test suite in parallel without issue.
7923 test_support.bind_port() has been fixed such that it will always
7924 return a unique port -- which wasn't always the case with the
7925 previous implementation, especially if socket options had been set
7926 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7927 new implementation of bind_port() will actually raise an exception
7928 if it is passed an AF_INET/SOCK_STREAM socket with either the
7929 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7930 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7931 the socket it's been passed. This currently only applies to
7932 Windows. This option prevents any other sockets from binding to the
7933 host/port we've bound to, thus removing the possibility of the
7934 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7935 when a second SOCK_STREAM socket binds and accepts to a host/port
7936 that's already been bound by another socket. The optional preferred
7937 port parameter to bind_port() has been removed. Under no
7938 circumstances should tests be hard coding ports!
7939
7940 test_support.find_unused_port() has also been introduced, which will
7941 pass a temporary socket object to bind_port() in order to obtain an
7942 unused port. The temporary socket object is then closed and
7943 deleted, and the port is returned. This method should only be used
7944 for obtaining an unused port in order to pass to an external program
7945 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7946 a parameter to a server-oriented class that doesn't give you direct
7947 access to the underlying socket used.
7948
7949 Finally, test_support.HOST has been introduced, which should be used
7950 for the host argument of any relevant socket calls (i.e. bind and
7951 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007952
7953 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007954 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

7956 test_asynchat and test_socket_ssl.
7957
Georg Brandl3ee81df2008-05-17 18:14:43 +00007958 It is now possible for multiple instances of the regression test

8226-----------------
8227
Fred Drakea8ee94b2008-03-01 02:45:07 +00008228- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008229 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008230
Georg Brandlad61bc82008-02-23 15:11:18 +00008231- Issue #2067: file.__exit__() now calls subclasses' close() method.
8232
8233- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008234
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008235- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008236 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008237
Eric Smitha73fbe72008-02-23 03:09:44 +00008238- Added the future_builtins module, which contains hex() and oct().
8239 These are the PEP 3127 version of these functions, designed to be
8240 compatible with the hex() and oct() builtins from Python 3.0. They
8241 differ slightly in their output formats from the existing, unchanged
8242 Python 2.6 builtins. The expected usage of the future_builtins
8243 module is:
8244 from future_builtins import hex, oct
8245
Eric Smith7ef40bf2008-02-20 23:34:22 +00008246- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8247 exponents for exponents with absolute value < 100. Follows C99
8248 standard. This is a change on Windows, which would use 3 digits.
8249 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8250 so that any alterations it does to the resulting string will be
8251 available in stringlib/formatter.h (for float.__format__).
8252
Eric Smith5a3c1352008-02-19 13:21:56 +00008253- Implemented PEP 3101, Advanced String Formatting. This adds a new
8254 builtin format(); a format() method for str and unicode; a
8255 __format__() method to object, str, unicode, int, long, float, and
8256 datetime; the class string.Formatter; and the C API
8257 PyObject_Format().
8258
Georg Brandl3ee81df2008-05-17 18:14:43 +00008259- Fixed several potential crashes, all caused by specially crafted
8260 __del__ methods exploiting objects in temporarily inconsistent
8261 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008262
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008263- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008264 prevent a possible crash: an Abstract Base Class would try to access
8265 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008266
Georg Brandl3ee81df2008-05-17 18:14:43 +00008267- Fixed repr() and str() of complex numbers with infinity or nan as
8268 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008269
Georg Brandl3ee81df2008-05-17 18:14:43 +00008270- Clear all free lists during a gc.collect() of the highest generation
8271 in order to allow pymalloc to free more arenas. Python may give back
8272 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008273
Georg Brandl3ee81df2008-05-17 18:14:43 +00008274- Issue #2045: Fix an infinite recursion triggered when printing a
8275 subclass of collections.defaultdict, if its default_factory is set
8276 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008277
Christian Heimesf75dbef2008-02-08 00:11:31 +00008278- Fixed a minor memory leak in dictobject.c. The content of the free
8279 list was not freed on interpreter shutdown.
8280
Georg Brandl21e99f42010-03-07 15:23:59 +00008281- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008282 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008283
Georg Brandl3ee81df2008-05-17 18:14:43 +00008284- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8285 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008286 to compact the internal free lists of pre-allocted ints and floats.
8287
Georg Brandl3ee81df2008-05-17 18:14:43 +00008288- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8289 calls. Python expected the return type int but the fork familie
8290 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008291
Georg Brandl3ee81df2008-05-17 18:14:43 +00008292- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8293 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008294
Georg Brandl3ee81df2008-05-17 18:14:43 +00008295- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8296 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008297
Georg Brandl3ee81df2008-05-17 18:14:43 +00008298- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8299 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008300
Georg Brandl3ee81df2008-05-17 18:14:43 +00008301- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8302 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008303
Georg Brandl3ee81df2008-05-17 18:14:43 +00008304- Patch #1473257: generator objects gain a gi_code attribute. This is
8305 the same object as the func_code attribute of the function that
8306 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008307
Georg Brandl3ee81df2008-05-17 18:14:43 +00008308- Issue #1920: "while 0" statements were completely removed by the
8309 compiler, even in the presence of an "else" clause, which is
8310 supposed to be run when the condition is false. Now the compiler
8311 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008312
Guido van Rossumeead05f2008-01-24 18:21:02 +00008313- A few crashers fixed: weakref_in_del.py (issue #1377858);
8314 loosing_dict_ref.py (issue #1303614, test67.py);
8315 borrowed_ref_[34].py (not in tracker).
8316
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008317- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008318 suppressed while an extension is loaded by calling SetErrorMode in
8319 dynload_win.c. The error is still reported properly.
8320
Georg Brandl3ee81df2008-05-17 18:14:43 +00008321- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008322 several extension methods and modules do not work without unicode
8323 support.
8324
Georg Brandl26543b12008-01-21 18:36:51 +00008325- Issue #1882: when compiling code from a string, encoding cookies in the
8326 second line of code were not always recognized correctly.
8327
Georg Brandl14404b62008-01-19 19:27:05 +00008328- Issue #1679: "0x" was taken as a valid integer literal.
8329
Georg Brandl6caad7d2008-01-26 14:19:22 +00008330- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008331 added.
8332
Christian Heimesc94e2b52008-01-14 04:13:37 +00008333- sys.float_info / PyFloat_GetInfo: The floating point information
8334 object was converted from a dict to a specialized structseq object.
8335
Georg Brandl3ee81df2008-05-17 18:14:43 +00008336- Patch #1816: Added sys.flags structseq. It exposes the status of
8337 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008338
Georg Brandl3ee81df2008-05-17 18:14:43 +00008339- Objects/structseq.c: Implemented new structseq representation. The
8340 patch makes structseqs (e.g. the return value of os.stat) more
8341 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008342
Georg Brandl3ee81df2008-05-17 18:14:43 +00008343- Patch #1700288: added a type attribute cache that caches method
8344 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008345
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008346- Bug #1776: __import__() no longer accepts filenames on any platform.
8347 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008348
Georg Brandlaed6c662008-01-07 17:25:53 +00008349- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8350
Georg Brandl3ee81df2008-05-17 18:14:43 +00008351- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8352 envvar and sys.dont_write_bytecode attribute. All these can be set
8353 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008354
Georg Brandl3ee81df2008-05-17 18:14:43 +00008355- Improve some exception messages when Windows fails to load an
8356 extension module. Now we get for example '%1 is not a valid Win32
8357 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008358
Georg Brandl3ee81df2008-05-17 18:14:43 +00008359- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008361- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8362 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008363
Christian Heimes0a8143f2007-12-18 23:22:54 +00008364- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008365 and INF. float("nan"), float("inf") and float("-inf") now work on
8366 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008367
Georg Brandl3ee81df2008-05-17 18:14:43 +00008368- Compiler now generates simpler and faster code for dictionary
8369 literals. The oparg for BUILD_MAP now indicates an estimated
8370 dictionary size. There is a new opcode, STORE_MAP, for adding
8371 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008372
Georg Brandl3ee81df2008-05-17 18:14:43 +00008373- Issue #1638: %zd configure test fails on Linux.

8383
Nick Coghlanef01d822007-12-03 12:55:17 +00008384- PEP 366: Allow explicit relative imports when executing modules
8385 inside packages with the -m switch via a new module level
8386 __package__ attribute.
8387
Georg Brandl3ee81df2008-05-17 18:14:43 +00008388- Issue #1402: Fix a crash on exit, when another thread is still
8389 running, and if the deallocation of its frames somehow calls the
8390 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008391

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008395 attribute of an empty cell object.
8396
Georg Brandl3ee81df2008-05-17 18:14:43 +00008397- Issue #1460: The utf-7 incremental decoder did not accept truncated
8398 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00008399
Georg Brandl3ee81df2008-05-17 18:14:43 +00008400- Patch #1739468: Directories and zipfiles containing a __main__.py
8401 file can now be directly executed by passing their name to the
8402 interpreter. The directory/zipfile is automatically inserted as the
8403 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008404
Georg Brandl3ee81df2008-05-17 18:14:43 +00008405- Issue #1265: Fix a problem with sys.settrace, if the tracing
8406 function uses a generator expression when at the same time the
8407 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008408
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008409- sets and frozensets now have an isdisjoint() method.
8410
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008411- optimize the performance of builtin.sum().
8412
Neal Norwitz44f326e2007-10-05 05:29:17 +00008413- Fix warnings found by the new version of the Coverity checker.
8414
Georg Brandl21e99f42010-03-07 15:23:59 +00008415- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008416 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8417 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008418
Georg Brandl3ee81df2008-05-17 18:14:43 +00008419- Issue #1686386: Tuple's tp_repr did not take into account the
8420 possibility of having a self-referential tuple, which is possible
8421 from C code. Nor did object's tp_str consider that a type's tp_str
8422 could do something that could lead to an inifinite recursion.
8423 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8424 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008425
Georg Brandl3ee81df2008-05-17 18:14:43 +00008426- Issue #1164: It was possible to trigger deadlock when using the
8427 'print' statement to write to a file since the GIL was not released
8428 as needed. Now PyObject_Print() does the right thing along with
8429 various tp_print implementations of the built-in types and those in
8430 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008431
Georg Brandl3ee81df2008-05-17 18:14:43 +00008432- Issue #1147: Exceptions were directly allowing string exceptions in
8433 their throw() method even though string exceptions no longer
8434 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008435

Brett Cannon1e534b52007-09-07 04:18:30 +00008439- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008440 PyObject_Call() never calling back out to Python code to trigger
8441 recursion depth updates/checks. Required the creation of a static
8442 RuntimeError instance in case normalizing an exception put the
8443 recursion check value past its limit. Fixes crashers
8444 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008445
Georg Brandl3ee81df2008-05-17 18:14:43 +00008446- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008459- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008460 __*__ attributes. (Some already existed, e.g., __doc__ and
8461 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008462
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008463- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00008470 "except E as target:". This is to provide forwards compatibility
8471 with Python 3.0.

8491
Guido van Rossum143b5642007-03-23 04:58:42 +00008492- Bug #1683368: The object.__init__() and object.__new__() methods are
8493 now stricter in rejecting excess arguments. The only time when
8494 either allows excess arguments is when it is not overridden and the
8495 other one is. For backwards compatibility, when both are
8496 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008497 warning later). Also, type.__init__() insists on the same signature
8498 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008500- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8501 object to complex using its __complex__() method before falling back
8502 to the __float__() method. Therefore, the functions in the cmath
8503 module now can operate on objects that define a __complex__()
8504 method.

8521
Georg Brandl7b9c5552007-03-12 14:30:05 +00008522- Bug #1678647: write a newline after printing an exception in any
8523 case, even when converting the value to a string failed.
8524
Georg Brandl871f1bc2007-03-12 13:17:36 +00008525- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008526 its argument, if it exists. If not, it will work like before. This
8527 allows customizing the output of dir() in the presence of a
8528 __getattr__().

8538 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008539
Georg Brandlaa2321b2007-03-07 00:40:28 +00008540- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008541 makes the filenames the warning module prints much more sensible
8542 when a PYTHONSTARTUP file is used.

8556 sq_ass_slice instead of the sq_slice slot.
8557
Georg Brandl3ee81df2008-05-17 18:14:43 +00008558- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00009183- unittest now verifies more of its assumptions. In particular,
9184 TestCase and TestSuite subclasses (not instances) are no longer
9185 accepted in TestSuite.addTest(). This should cause no
9186 incompatibility since it never made sense with ordinary subclasses
9187 -- the failure just occurred later, with a more cumbersome
9188 exception.

9461 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009462
Georg Brandl3ee81df2008-05-17 18:14:43 +00009463- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9464 with RFC 3207 and forgets any knowledge obtained from the server not
9465 obtained from the TLS negotiation itself. Patch contributed by Bill
9466 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009467
Georg Brandl3ee81df2008-05-17 18:14:43 +00009468- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009469 that the SMTP.starttls() caller no longer needs to call ehlo()
9470 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009471 does not claim to support starttls. Adds the
9472 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9553 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9554 silently miscode subclasses of those types. Now, it raises a
9555 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009556

Georg Brandl3ee81df2008-05-17 18:14:43 +00009571 time so that opening a database previously created with the DB_DUP
9572 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9573 opens. Specifically: dictionary assignment to a DB object will
9574 replace all values for a given key when the database allows
9575 duplicate values. DB users should use DB.put(k, v) when they want
9576 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009577

9583 characters with ASCII value less than 32. Also, it correctly quotes
9584 dots only if they occur on a single line, as opposed to the previous
9585 behavior of quoting dots if they are the second character of any
9586 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009587

Georg Brandl3ee81df2008-05-17 18:14:43 +00009921- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9922 to ``PyTuple_SetItem``, it can be used to populate a brand new
9923 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00009925- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009927- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9928 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9929 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009930
9931- Patch #1720595: add T_BOOL to the range of structmember types.
9932
9933- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9934 ``PyFloat_GetInfo()`` to the float API.
9935
Georg Brandl3ee81df2008-05-17 18:14:43 +00009936- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9937 of w# format code incorrectly truncated the length to an int, even
9938 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9939 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009940
Georg Brandl3ee81df2008-05-17 18:14:43 +00009941- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9942 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009944- PEP 3123: Provide forward compatibility with Python 3.0, while
9945 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9946 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009948- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9949 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009950
9951- Patch #1733960: Allow T_LONGLONG to accept ints.
9952
9953- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9954
Christian Heimes000a0742008-01-03 22:16:32 +00009955- Added a new API function ``PyImport_ImportModuleNoBlock``.

9958
9959- Fix some leftovers from the conversion from int to Py_ssize_t
9960 (relevant to strings and sequences of more than 2**31 items).
9961
9962- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9963 outside of pystate.c and should not be necessary.
9964
Georg Brandl3ee81df2008-05-17 18:14:43 +00009965- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9966 absolute imports. In earlier versions they might have used relative
9967 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009968
Georg Brandl3ee81df2008-05-17 18:14:43 +00009969- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9970 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009971
Georg Brandl3ee81df2008-05-17 18:14:43 +00009972- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009978- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9979 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9980 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9981 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009995- Removed the macfs module. It had been deprecated since Python 2.5.
9996 This lead to the deprecation of macostools.touched() as it relied
9997 solely on macfs and was a no-op under OS X.
