98 int.__pow__. These overflow checks were causing int.__pow__ to produce
99 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100100 compiler optimizing the check away. Also fix similar overflow checks
101 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Antoine Pitrou16166452011-07-12 22:04:20 +0200113- Issue #12149: Update the method cache after a type's dictionnary gets
114 cleared by the garbage collector. This fixes a segfault when an instance
115 and its type get caught in a reference cycle, and the instance's
116 deallocator calls one of the methods on the type (e.g. when subclassing
117 IOBase). Diagnosis and patch by Davide Rizzo.

Victor Stinner08563d92011-05-30 23:44:13 +0200126 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
127 raw_input() interrupted by CTRL+c.
128
Łukasz Langa7a153902011-10-18 17:16:00 +0200129- Issue #10860: httplib now correctly handles an empty port after port
130 delimiter in URLs.

Florent Xiclunac2279652012-02-12 14:49:03 +0100170- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100171 has left two versions of customize_compiler, the original in
172 distutils.sysconfig and another copy in distutils.ccompiler, with some
173 parts of distutils calling one and others using the other.
174 Complete the revert back to only having one in distutils.sysconfig as
175 is the case in 3.x.
176
Ned Deily0d0ea482012-02-10 12:59:06 +0100177- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
178 Distutils-based packages with C extension modules may fail because
179 Apple has removed gcc-4.2, the version used to build python.org
180 64-bit/32-bit Pythons. If the user does not explicitly override
181 the default C compiler by setting the CC environment variable,
182 Distutils will now attempt to compile extension modules with clang
183 if gcc-4.2 is required but not found. Also as a convenience, if
184 the user does explicitly set CC, substitute its value as the default
185 compiler in the Distutils LDSHARED configuration variable for OS X.
186 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
187 SDK, neither of which are available in Xcode 4. This change does not
188 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700461- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
462 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
463 interpreter process. This could cause failures in non-Distutils subprocesses
464 and was unreliable since tests or user programs could modify the interpreter
465 environment after Distutils set it. Instead, have Distutils set the the
466 deployment target only in the environment of each build subprocess. It is
467 still possible to globally override the default by setting
468 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
469 greater or equal to the default value, the value with which the interpreter
470 was built.

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

1448 This prevents user-created self-referencing ordered dictionaries from
1449 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001911- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1912 start byte and the continuation byte(s) are now considered invalid, instead
1913 of the number of bytes specified by the start byte.
1914 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1915 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1916 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001925- Issue #8748: Fix two issues with comparisons between complex and integer
1926 objects. (1) The comparison could incorrectly return True in some cases
1927 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1928 (2) The comparison raised an OverflowError for large integers, leading
1929 to unpredictable exceptions when combining integers and complex objects

Mark Dickinson81336372010-05-30 12:12:25 +00001932- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00002069- Issue #1533: Fix inconsistency in range function argument processing: any
2070 non-float non-integer argument is now converted to an integer (if possible)
2071 using its __int__ method. Previously, only small arguments were treated this
2072 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00002081 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00002082 benefit compared to the dynamic memory allocation fallback. Patch by

2109 inheritance with the underlying socket object. The cheap inheritance has been
2110 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00002123- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2124 operation raises multiple signals and more than one of those signals is
2125 trapped, the specification determines the order in which the signals should be
2126 handled. In many cases this order wasn't being followed, leading to the wrong
2127 Python exception being raised.

2294Core and Builtins
2295-----------------
2296
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002297- Issue #7301: Add environment variable $PYTHONWARNINGS.
2298
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002299- Issue #8329: Don't return the same lists from select.select when no fds are
2300 changed.
2301
Georg Brandlfee0f442010-05-22 21:26:21 +00002302- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002303 on 64-bit machines. The shift count for either left or right shift is
2304 permitted to be up to sys.maxsize.
2305
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002306- Ensure that tokenization of identifiers is not affected by locale.
2307
Georg Brandlfee0f442010-05-22 21:26:21 +00002308- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002309
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002310- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2311
Georg Brandlfee0f442010-05-22 21:26:21 +00002312- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2313 with a non-empty format string. This is an effort to future-proof user
2314 code. If a derived class does not currently implement __format__ but later
2315 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002316 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002317 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002318
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002319- Issue #8268: Old-style classes (not just instances) now support weak
2320 references.
2321
Georg Brandlfee0f442010-05-22 21:26:21 +00002322- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2323 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00002324
Victor Stinnerc7790ed2010-03-22 12:36:28 +00002325- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00002327- Issue #6474: Make error message from passing an inadequate number of keyword
2328 arguments to a function correct.
2329
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002330- Issue #8164: Don't allow lambda functions to have a docstring.
2331
Victor Stinner66644262010-03-10 22:30:19 +00002332- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002333 (SIGINT). If an error occurs while importing the site module, the error is
2334 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002335 module.
2336
Collin Winter001a3952010-03-18 21:54:01 +00002337- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00002342- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
2343
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002344- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002345 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2346 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002347
Benjamin Peterson76a23c12010-04-04 23:23:22 +00002348- Issue #8310: Allow dis to examine new style classes.
2349
Georg Brandlfee0f442010-05-22 21:26:21 +00002350- Issue #8257: The Decimal construct now accepts a float instance directly,
2351 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002352
2353 >>> Decimal(1.1)
2354 Decimal('1.100000000000000088817841970012523233890533447265625')
2355
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002356- collections.Counter() now supports a subtract() method.
2357
Georg Brandlfee0f442010-05-22 21:26:21 +00002358- The functools module now has a total_ordering() class decorator to simplify
2359 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002360
Georg Brandlfee0f442010-05-22 21:26:21 +00002361- The functools module also adds cmp_to_key() as a tool to transition old-style
2362 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002363
Georg Brandlfee0f442010-05-22 21:26:21 +00002364- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2365 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002366
Georg Brandlfee0f442010-05-22 21:26:21 +00002367- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2368 InvalidOperation instead of returning False. (Comparisons involving a quiet
2369 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2370 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002371
Georg Brandlfee0f442010-05-22 21:26:21 +00002372- Issue #2531: Comparison operations between floats and Decimal instances now
2373 return a result based on the numeric values of the operands; previously they
2374 returned an arbitrary result based on the relative ordering of id(float) and
2375 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002376
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002377- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002378 argument `-` which tells it to read files to compile from stdin. Each line is
2379 read on demand and the named file is compiled immediately. (Original patch by
2380 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002381
Georg Brandlfee0f442010-05-22 21:26:21 +00002382- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2383 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002385- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2386 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002387 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002388
Georg Brandlfee0f442010-05-22 21:26:21 +00002389- Comparisons using one of <, <=, >, >= between a complex instance and a
2390 Fractions instance now raise TypeError instead of returning True/False. This
2391 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2392 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002393
Michael Foorde6410c52010-03-29 20:04:23 +00002394- Addition of ``WeakSet`` to the ``weakref`` module.

2402
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002403- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002404 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2405 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002406
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002407- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2408 deprecated.
2409
Georg Brandlfee0f442010-05-22 21:26:21 +00002410- Issue #7860: platform.uname now reports the correct 'machine' type when Python
2411 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00002412

Georg Brandlfee0f442010-05-22 21:26:21 +00002416- Issue #8201: logging: Handle situation of non-ASCII and Unicode logger names
2417 existing at the same time, causing a Unicode error when configuration code
2418 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00002419
Georg Brandlfee0f442010-05-22 21:26:21 +00002420- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
2421 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00002422
Antoine Pitroueee91cd2010-03-26 19:27:16 +00002423- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
2424 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
2425 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00002426
Florent Xiclunacf82fa62010-03-21 12:27:20 +00002427- Issue #8179: Fix macpath.realpath() on a non-existing path.

2433 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +00002434
Matthias Klose8b411682010-03-16 10:48:52 +00002435- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
2436 with Tcl/Tk-8.5.

2441 locale.
Matthias Klose358e7ff2010-03-15 13:42:23 +00002442
Georg Brandlfee0f442010-05-22 21:26:21 +00002443- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002447- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002448 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2449 log file to compute the next rollover time. If the log file does not exist,
2450 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002451
Georg Brandlba83f822010-03-14 09:50:54 +00002452- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

2459
Georg Brandlba83f822010-03-14 09:50:54 +00002460- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2461 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2462 This is a behavior change, so email's minor version number is now bumped, to
2463 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00002464

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002491- Issue #8300: When passing a non-integer argument to struct.pack with any
2492 integer format code, struct.pack first attempts to convert the non-integer
2493 using its __index__ method. If that method is non-existent or raises
2494 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00002496- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2497 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2498 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002499 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2500 inconsistent: __int__ was used for some integer codes but not for others, and
2501 the set of integer codes for which it was used differed between native packing
2502 and standard packing.)

2906Core and Builtins
2907-----------------
2908
Georg Brandlba83f822010-03-14 09:50:54 +00002909- The ``__complex__()`` method is now looked up on the class of instances to
2910 make it consistent with other special methods.

2914
Mark Dickinson1b34d252010-01-01 17:27:30 +00002915- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002916 DeprecationWarning when passed a float argument where an integer was expected.
2917 These functions and methods now raise TypeError instead. The majority of the
2918 effects of this change are in the extension modules, but some core functions
2919 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2920 and many unicode/str methods.

2934 of integers: the result of a/b is now correctly rounded for ints a and b (at
2935 least on IEEE 754 platforms), and in particular does not depend on the
2936 internal representation of a long.

2944
Georg Brandlba83f822010-03-14 09:50:54 +00002945 These executables now work properly with the arch(1) command: ``arch -ppc
2946 python`` will start a universal binary version of python in PPC mode (unlike

3087 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003088
Georg Brandlba83f822010-03-14 09:50:54 +00003089- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3090 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003091
Georg Brandlba83f822010-03-14 09:50:54 +00003092- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3093 1e-100 used to raise OverflowError, but now gives the requested 120
3094 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003102
Georg Brandlba83f822010-03-14 09:50:54 +00003103- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3104 decimal string that's guaranteed to round back to x under correct rounding
3105 (with round-half-to-even rounding mode). Previously it gave a string based on
3106 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3107 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3108 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003109
Georg Brandlba83f822010-03-14 09:50:54 +00003110- Issue #7117: On almost all platforms: float-to-string and string-to-float
3111 conversions within Python are now correctly rounded. Places these conversions
3112 occur include: str for floats and complex numbers; the float and complex
3113 constructors; old-style and new-style numeric formatting; serialization and
3114 deserialization of floats and complex numbers using marshal, pickle and json;
3115 parsing of float and imaginary literals in Python code; Decimal-to-float
3116 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003117
Georg Brandlba83f822010-03-14 09:50:54 +00003118 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3119 providing correctly-rounded strtod and dtoa C functions. This code is
3120 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3121 the C compiler. There may be a small number of platforms on which correct
3122 operation of this code cannot be guaranteed, so the code is not used: notably,
3123 this applies to platforms where the C double format is not IEEE 754 binary64,
3124 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3125 and Python's configure script is unable to determine how to change the FPU
3126 precision. On these platforms conversions use the platform strtod and dtoa,
3127 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003128
Georg Brandlba83f822010-03-14 09:50:54 +00003129- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3130 uses the correctly-rounded string <-> float conversions described above (when
3131 available), and so produces correctly rounded results that will display nicely
3132 under the float repr. There are two related small changes: (1) round now
3133 accepts any class with an ``__index__()`` method for its second argument (but
3134 no longer accepts floats for the second argument), and (2) an excessively
3135 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3136 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003278
Georg Brandlba83f822010-03-14 09:50:54 +00003279 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3280 (2) parsing of strings representing infinities and nans was locale aware; and
3281 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003283- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3284 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3285 but with at least one decimal point and with a default precision
3286 of 12. Previously, the behavior the same but with a default precision of 6.
3287 This more closely matches ``str()``, and reduces surprises when adding
3288 alignment flags to the empty presentation type. This also affects the new
3289 complex.__format__ in the same way.
3290
3291- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3292 classtype's, even if it was None. property now inserts the __doc__ into the

3363 internal representation of integers, for performance reasons. Base 2**30 is
3364 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl6425a2f2008-12-28 11:54:53 +00003452- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003453 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003454
Skip Montanarof205c132008-12-23 03:30:15 +00003455- Added test case to ensure attempts to read from a file opened for writing
3456 fail.
3457
Georg Brandlba83f822010-03-14 09:50:54 +00003458- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
3459 elapsed times, not only when some objects are uncollectable/unreachable.
3460 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00003461
Mark Dickinson1a707982008-12-17 16:14:37 +00003462- Issue #3439: Add a bit_length method to int and long.
3463
Georg Brandlba83f822010-03-14 09:50:54 +00003464- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
3465 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00003466
Georg Brandlba83f822010-03-14 09:50:54 +00003467- Issue #4597: Fixed exception handling when the __exit__ function of a context
3468 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00003469
Georg Brandlba83f822010-03-14 09:50:54 +00003470- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00003471
Georg Brandlba83f822010-03-14 09:50:54 +00003472- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3473 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3474 instances. On a typical machine this saves 3 bytes of memory (on average) per
3475 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003476
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003477- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3478 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3479 instead of throwing a MemoryError.
3480
Georg Brandlba83f822010-03-14 09:50:54 +00003481- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3482 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003483
Benjamin Petersonc078f922008-11-21 22:27:24 +00003484- Issue #4367: Python would segfault during compiling when the unicodedata
3485 module couldn't be imported and \N escapes were present.
3486
Georg Brandlba83f822010-03-14 09:50:54 +00003487- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3488 file objects with closefd=False. The file descriptor is still kept open but
3489 the file object behaves like a closed file. The ``FileIO`` object also got a
3490 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003491
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003492- Issue #4348: Some bytearray methods returned that didn't cause any change to
3493 the bytearray, returned the same bytearray instead of a copy.
3494
Georg Brandlba83f822010-03-14 09:50:54 +00003495- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00003497- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3498
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003499- Issue #4048: The parser module now correctly validates relative imports.
3500
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003501- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3502 exec statement.
3503
Georg Brandlba83f822010-03-14 09:50:54 +00003504- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3505 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003506
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003507- Issue #4209: Enabling unicode_literals and the print_function in the same
3508 __future__ import didn't work.
3509
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003510- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003511 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003512
Georg Brandlba83f822010-03-14 09:50:54 +00003513- On windows, ``os.chdir()`` given unicode was not working if
3514 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3515 this code path is really executed because I cannot move to such directory on
3516 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003517
Georg Brandlba83f822010-03-14 09:50:54 +00003518- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3519 element is temporarily replaced with an equivalent frozenset. But the
3520 eventual KeyError would always report the empty ``frozenset()`` as the missing
3521 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003522
Georg Brandlba83f822010-03-14 09:50:54 +00003523- Issue #4509: Various issues surrounding resize of bytearray objects to which
3524 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00003525
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00003526- Issue #4748: Lambda generators no longer return a value.
3527

3529
Gregory P. Smithae91d092009-03-02 05:13:57 +00003530- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
3531
Georg Brandlba83f822010-03-14 09:50:54 +00003532- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
3533 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00003534
Matthias Klose91a3b9e2009-04-05 21:19:13 +00003535- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3536 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003537
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003538- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3539 returned them on 64bit platforms.
3540
Walter Dörwalded960ac2009-05-03 22:36:33 +00003541- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3542 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3543 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3544 of using the replace error handler in PyUnicode_DecodeUTF8().
3545
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003546- Issue #3739: The unicode-internal encoder now reports the number of characters
3547 consumed like any other encoder (instead of the number of bytes).
3548
Georg Brandlba83f822010-03-14 09:50:54 +00003549- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3550 allocator will be automatically disabled when running under Valgrind. This
3551 gives improved memory leak detection when running under Valgrind, while taking
3552 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00003577- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
3578 ownership when the group is not forced, because the group may be different
3579 from the user's group and inherit from its container when the test is run.

3622 execute file paths that refer to source or compiled Python files as well as
3623 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00003624 __main__.py file. This allows applications that run other Python scripts to

4718 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4719 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4720 neither __int__ nor __long__, TypeError used to be raised (with a
4721 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4722 struct.error in other cases.

4725 argument with an __int__ method can be packed, but use of this feature

4815 should cause a test to be skipped are now done using import_module from test
4816 support, which does the conversion.

4918
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004919- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4920 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4921 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4922 ``printf`` function, whereas PyString_FromFormat has an independent
4923 implementation and uses "%zd" on all platforms for size_t values.
4924 This makes a difference on win64, where ``printf`` needs "%Id" to display
4925 64bit values.

4931 object; previously an int would be returned for small values. the __long__
4932 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00004941 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004942 was correctly parsed but parsing of subsequent arguments failed.
4943
Vinay Sajip35e3b032008-09-01 14:33:59 +00004944- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004945 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4946 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4947 when given a tuple of classes as second argument, were looking up
4948 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4949 type object.
4950
Neal Norwitz18aa3882008-08-24 05:04:52 +00004951- Fix crashes on memory allocation failure found with failmalloc.

5094-----------------
5095
Guido van Rossumf8402962008-08-20 15:01:50 +00005096- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5097 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5098 extensions do not automatically benefit from the class attribute
5099 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5100 to their tp_flags field if they care. This is a backwards
5101 compatibility feature; in 3.0, all types will use the cache by
5102 default.
5103
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005104- Keyword arguments can now follow starred arguments. (``f(a, *args,
5105 keyword=23)`` is now valid syntax.)
5106
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005107- ctypes function pointers that are COM methods have a boolean True

Mark Dickinsonb6467572008-08-04 21:30:09 +00005117- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5118 ValueError consistently across platforms.
5119
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005120- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5121 (64bit Unix, for example), unichr() would truncate its argument and return
5122 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

5127 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5128
Antoine Pitrou92f82162008-07-25 22:22:08 +00005129- Issue #1819: function calls with several named parameters are now on

Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005132- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5133 the python debugger steps into a class statement: the free variables (local
5134 variables defined in an outer scope) would be deleted from the outer scope.
5135
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005136- Issue #2620: Overflow checking when allocating or reallocating memory
5137 was not always being done properly in some python types and extension
5138 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5139 all been updated to perform better checks and places in the code that
5140 would previously leak memory on the error path when such an allocation
5141 failed have been fixed.

5150
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005151- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5152 version reported by these tools does not necessarily follow the python
5153 version numbering scheme, so the module is less strict when parsing it.
5154
Nick Coghlanf70385a2008-08-18 12:42:46 +00005155- Issue #2235: Added Py3k warnings for types which will become unhashable
5156 under the stricter __hash__ inheritance rules in 3.0. Several types
5157 which did not meet the rules for hash invariants and were already
5158 unhashable in 3.0 have now been explicitly flagged as unhashable in
5159 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,

Brett Cannonbf3157b2008-08-14 05:00:03 +00005193- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5194 since mimetools itself is deprecated. Because modules are cached, all
5195 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

5214 it wasn't initialized during instantiation.
5215
Brett Cannon3aa2a492008-08-06 22:28:09 +00005216- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5217 the reload() built-in has been removed.
5218
Brett Cannon7e30b672008-08-04 21:52:25 +00005219- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00005231 asking for a specific length. This problem only affected files opened
5232 using the new "io" module, not the built-in open() function.

5258 file name rather than a ZipInfo instance, so files are extracted with
5259 mode 0600 rather than 000 under Unix.
5260
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005261- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5262 argument in python 2.5, this broke code that subclassed Popen to include its

5274 interaction with the tp_hash slot (added in 2.6b2) are now documented
5275
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005276- Issue #643841: The language reference now provides more detailed
5277 coverage of the lookup process for special methods. The disclaimers
5278 regarding lack of coverage of new-style classes have also been
5279 removed, since the coverage is now fairly reasonable.

5283================================
5284
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005285*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005287Core and Builtins
5288-----------------
5289
Georg Brandl3e483f62008-07-16 22:57:41 +00005290- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5291 its methods now allow for items objects that can be converted to
5292 an integer using operator.index().
5293
Mark Dickinson64b7e502008-07-16 09:40:03 +00005294- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5295 produced a ValueError instead of giving the correct float.
5296
Eric Smitha5fa5a22008-07-16 00:11:49 +00005297- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5298 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5299
Mark Dickinson7103aa42008-07-15 19:08:33 +00005300- Issue #3008: the float type has a new instance method 'float.hex'
5301 and a new class method 'float.fromhex' to convert floating-point
5302 numbers to and from hexadecimal strings, respectively.
5303
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005304- Issue #2235: __hash__ is once again inherited by default. To allow
5305 collections.Hashable to remain meaningful in the presence of the
5306 default hash implementation (object.__hash__), it is now possible
5307 to explicit block inheritance of hash by setting __hash__=None at
5308 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5309 level.
5310
Nick Coghlanb028f502008-07-13 14:52:36 +00005311- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5312 the parent module cannot be found while performing an absolute import.
5313 This means that an incorrectly defined __package__ attribute will
5314 now only prevent relative imports in that module rather than causing
5315 all imports from that module to fail.
5316
Nick Coghlan14ff9942008-07-08 14:21:42 +00005317- Issue #2517: Allow unicode messages in Exceptions again by correctly
5318 bypassing the instance dictionary when looking up __unicode__ on
5319 new-style classes.
5320
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005321- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5322 set to a custom object whose write() method happens to install
5323 another file in sys.stdout.
5324
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005325- Issue #3088: Corrected a race condition in classes derived from
5326 threading.local: the first member set by a thread could be saved in
5327 another thread's dictionary.
5328
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005329- Issue #3004: Minor change to slice.indices(): the start and stop
5330 arguments are now treated identically, making the behaviour easier
5331 to describe and understand. For example, slice(None, -10,
5332 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5333 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5334 10, -1).
5335
Georg Brandl278fc502008-07-19 12:46:12 +00005336- Issue #3219: Calling a function with repeated keyword arguments,
5337 f(a=2, a=23), would not cause a syntax error. This was a regression
5338 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005339
Georg Brandl278fc502008-07-19 12:46:12 +00005340- Issue #2862: Make int and float freelist management consistent with
5341 other freelists. Changes their CompactFreeList apis into
5342 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005343

5346
Thomas Heller57adf222008-08-14 19:10:48 +00005347- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5348 api functions without holding the GIL, which could lead to a fatal
5349 error when they failed.
5350
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005351- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5360 ForkingPickler.register() to resolve conflict with ctypes.
5361
Vinay Sajip51e65192008-07-18 09:01:10 +00005362- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00005364- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5365 a valid dlerror() message.
5366
Thomas Heller2bad6572008-07-15 17:19:50 +00005367- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5368 incomplete structure was created.
5369
Brett Cannon3d0b9f02008-07-13 01:15:07 +00005370- Issue #3339: dummy_thread.acquire() should not return None.

5373
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005374- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005375
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005376- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5377 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005378 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005379 content-length. The problem had been corrected in the 2.4 branch, but never
5380 merged into trunk.
5381
Georg Brandle78fbcc2008-07-05 10:13:36 +00005382- Issue #2663: add filtering capability to shutil.copytree().

5787 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005788 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005789
5790 This is controlled by the configure argument ``--with-universal-archs``:
5791
5792 - ``--with-universal-archs=all``: install 4-way universal
5793
5794 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5795
5796 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5797
5798 This option should be used in combination with ``--enable-universalsdk=``.
5799
5800 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 +00005850- Issue #1631171: Re-implement the 'warnings' module in C (the
5851 original Python code has been kept as backup). This will allow for
5852 using the 'warning's machinery in such places as the parser where
5853 use of pure Python code is not possible. Both the ``showarning()``
5854 and ``formatwarning()`` gain an optional 'line' argument which is
5855 not called by default for backwards-compatibility reasons. Setting
5856 ``warnings.showwarning()`` to an implementation that lacks support
5857 for the ``line`` argument will raise a DeprecationWarning.

5881
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005882- The getpass module has been improved on Unix. It now uses /dev/tty
5883 by default and uses stderr instead of stdout. A GetPassWarning is
5884 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005920- Issue #2550: The approach used by client/server code for obtaining
5921 ports to listen on in network-oriented tests has been refined in an
5922 effort to facilitate running multiple instances of the entire
5923 regression test suite in parallel without issue.
5924 test_support.bind_port() has been fixed such that it will always
5925 return a unique port -- which wasn't always the case with the
5926 previous implementation, especially if socket options had been set
5927 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5928 new implementation of bind_port() will actually raise an exception
5929 if it is passed an AF_INET/SOCK_STREAM socket with either the
5930 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5931 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5932 the socket it's been passed. This currently only applies to
5933 Windows. This option prevents any other sockets from binding to the
5934 host/port we've bound to, thus removing the possibility of the
5935 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5936 when a second SOCK_STREAM socket binds and accepts to a host/port
5937 that's already been bound by another socket. The optional preferred
5938 port parameter to bind_port() has been removed. Under no
5939 circumstances should tests be hard coding ports!
5940
5941 test_support.find_unused_port() has also been introduced, which will
5942 pass a temporary socket object to bind_port() in order to obtain an
5943 unused port. The temporary socket object is then closed and
5944 deleted, and the port is returned. This method should only be used
5945 for obtaining an unused port in order to pass to an external program
5946 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5947 a parameter to a server-oriented class that doesn't give you direct
5948 access to the underlying socket used.
5949
5950 Finally, test_support.HOST has been introduced, which should be used
5951 for the host argument of any relevant socket calls (i.e. bind and
5952 connect).

6227-----------------
6228
Fred Drakea8ee94b2008-03-01 02:45:07 +00006229- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006230 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006231
Georg Brandlad61bc82008-02-23 15:11:18 +00006232- Issue #2067: file.__exit__() now calls subclasses' close() method.
6233
6234- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006235
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006236- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006237 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006238
Eric Smitha73fbe72008-02-23 03:09:44 +00006239- Added the future_builtins module, which contains hex() and oct().
6240 These are the PEP 3127 version of these functions, designed to be
6241 compatible with the hex() and oct() builtins from Python 3.0. They
6242 differ slightly in their output formats from the existing, unchanged
6243 Python 2.6 builtins. The expected usage of the future_builtins
6244 module is:
6245 from future_builtins import hex, oct
6246
Eric Smith7ef40bf2008-02-20 23:34:22 +00006247- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6248 exponents for exponents with absolute value < 100. Follows C99
6249 standard. This is a change on Windows, which would use 3 digits.
6250 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6251 so that any alterations it does to the resulting string will be
6252 available in stringlib/formatter.h (for float.__format__).
6253
Eric Smith5a3c1352008-02-19 13:21:56 +00006254- Implemented PEP 3101, Advanced String Formatting. This adds a new
6255 builtin format(); a format() method for str and unicode; a
6256 __format__() method to object, str, unicode, int, long, float, and
6257 datetime; the class string.Formatter; and the C API
6258 PyObject_Format().
6259
Georg Brandl3ee81df2008-05-17 18:14:43 +00006260- Fixed several potential crashes, all caused by specially crafted
6261 __del__ methods exploiting objects in temporarily inconsistent
6262 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006263
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006264- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006265 prevent a possible crash: an Abstract Base Class would try to access
6266 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006267
Georg Brandl3ee81df2008-05-17 18:14:43 +00006268- Fixed repr() and str() of complex numbers with infinity or nan as
6269 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006270
Georg Brandl3ee81df2008-05-17 18:14:43 +00006271- Clear all free lists during a gc.collect() of the highest generation
6272 in order to allow pymalloc to free more arenas. Python may give back
6273 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006274
Georg Brandl3ee81df2008-05-17 18:14:43 +00006275- Issue #2045: Fix an infinite recursion triggered when printing a
6276 subclass of collections.defaultdict, if its default_factory is set
6277 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006278
Christian Heimesf75dbef2008-02-08 00:11:31 +00006279- Fixed a minor memory leak in dictobject.c. The content of the free
6280 list was not freed on interpreter shutdown.
6281
Georg Brandl21e99f42010-03-07 15:23:59 +00006282- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006283 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006284
Georg Brandl3ee81df2008-05-17 18:14:43 +00006285- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6286 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006287 to compact the internal free lists of pre-allocted ints and floats.
6288
Georg Brandl3ee81df2008-05-17 18:14:43 +00006289- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6290 calls. Python expected the return type int but the fork familie
6291 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006292
Georg Brandl3ee81df2008-05-17 18:14:43 +00006293- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6294 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006295
Georg Brandl3ee81df2008-05-17 18:14:43 +00006296- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6297 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006298
Georg Brandl3ee81df2008-05-17 18:14:43 +00006299- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6300 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006301
Georg Brandl3ee81df2008-05-17 18:14:43 +00006302- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6303 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006304
Georg Brandl3ee81df2008-05-17 18:14:43 +00006305- Patch #1473257: generator objects gain a gi_code attribute. This is
6306 the same object as the func_code attribute of the function that
6307 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006308
Georg Brandl3ee81df2008-05-17 18:14:43 +00006309- Issue #1920: "while 0" statements were completely removed by the
6310 compiler, even in the presence of an "else" clause, which is
6311 supposed to be run when the condition is false. Now the compiler
6312 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006313
Guido van Rossumeead05f2008-01-24 18:21:02 +00006314- A few crashers fixed: weakref_in_del.py (issue #1377858);
6315 loosing_dict_ref.py (issue #1303614, test67.py);
6316 borrowed_ref_[34].py (not in tracker).
6317
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006318- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006319 suppressed while an extension is loaded by calling SetErrorMode in
6320 dynload_win.c. The error is still reported properly.
6321
Georg Brandl3ee81df2008-05-17 18:14:43 +00006322- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006323 several extension methods and modules do not work without unicode
6324 support.
6325
Georg Brandl26543b12008-01-21 18:36:51 +00006326- Issue #1882: when compiling code from a string, encoding cookies in the
6327 second line of code were not always recognized correctly.
6328
Georg Brandl14404b62008-01-19 19:27:05 +00006329- Issue #1679: "0x" was taken as a valid integer literal.
6330
Georg Brandl6caad7d2008-01-26 14:19:22 +00006331- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006332 added.
6333
Christian Heimesc94e2b52008-01-14 04:13:37 +00006334- sys.float_info / PyFloat_GetInfo: The floating point information
6335 object was converted from a dict to a specialized structseq object.
6336
Georg Brandl3ee81df2008-05-17 18:14:43 +00006337- Patch #1816: Added sys.flags structseq. It exposes the status of
6338 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006339
Georg Brandl3ee81df2008-05-17 18:14:43 +00006340- Objects/structseq.c: Implemented new structseq representation. The
6341 patch makes structseqs (e.g. the return value of os.stat) more
6342 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006343
Georg Brandl3ee81df2008-05-17 18:14:43 +00006344- Patch #1700288: added a type attribute cache that caches method
6345 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006346
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006347- Bug #1776: __import__() no longer accepts filenames on any platform.
6348 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006349
Georg Brandlaed6c662008-01-07 17:25:53 +00006350- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6351
Georg Brandl3ee81df2008-05-17 18:14:43 +00006352- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6353 envvar and sys.dont_write_bytecode attribute. All these can be set
6354 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006355
Georg Brandl3ee81df2008-05-17 18:14:43 +00006356- Improve some exception messages when Windows fails to load an
6357 extension module. Now we get for example '%1 is not a valid Win32
6358 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006359
Georg Brandl3ee81df2008-05-17 18:14:43 +00006360- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006362- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6363 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006364
Christian Heimes0a8143f2007-12-18 23:22:54 +00006365- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006366 and INF. float("nan"), float("inf") and float("-inf") now work on
6367 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006368
Georg Brandl3ee81df2008-05-17 18:14:43 +00006369- Compiler now generates simpler and faster code for dictionary
6370 literals. The oparg for BUILD_MAP now indicates an estimated
6371 dictionary size. There is a new opcode, STORE_MAP, for adding
6372 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006373
Georg Brandl3ee81df2008-05-17 18:14:43 +00006374- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006379- Issue #1538: Avoid copying string in split/rsplit if the split char
6380 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006381
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006382- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006383 SystemError.
6384
Nick Coghlanef01d822007-12-03 12:55:17 +00006385- PEP 366: Allow explicit relative imports when executing modules
6386 inside packages with the -m switch via a new module level
6387 __package__ attribute.
6388
Georg Brandl3ee81df2008-05-17 18:14:43 +00006389- Issue #1402: Fix a crash on exit, when another thread is still
6390 running, and if the deallocation of its frames somehow calls the
6391 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006392

6402 file can now be directly executed by passing their name to the
6403 interpreter. The directory/zipfile is automatically inserted as the
6404 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006405
Georg Brandl3ee81df2008-05-17 18:14:43 +00006406- Issue #1265: Fix a problem with sys.settrace, if the tracing
6407 function uses a generator expression when at the same time the
6408 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006409
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006410- sets and frozensets now have an isdisjoint() method.
6411
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006412- optimize the performance of builtin.sum().
6413
Neal Norwitz44f326e2007-10-05 05:29:17 +00006414- Fix warnings found by the new version of the Coverity checker.
6415
Georg Brandl21e99f42010-03-07 15:23:59 +00006416- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006417 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6418 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006419
Georg Brandl3ee81df2008-05-17 18:14:43 +00006420- Issue #1686386: Tuple's tp_repr did not take into account the
6421 possibility of having a self-referential tuple, which is possible
6422 from C code. Nor did object's tp_str consider that a type's tp_str
6423 could do something that could lead to an inifinite recursion.
6424 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6425 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006426
Georg Brandl3ee81df2008-05-17 18:14:43 +00006427- Issue #1164: It was possible to trigger deadlock when using the
6428 'print' statement to write to a file since the GIL was not released
6429 as needed. Now PyObject_Print() does the right thing along with
6430 various tp_print implementations of the built-in types and those in
6431 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006432
Georg Brandl3ee81df2008-05-17 18:14:43 +00006433- Issue #1147: Exceptions were directly allowing string exceptions in
6434 their throw() method even though string exceptions no longer
6435 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006436

Brett Cannon1e534b52007-09-07 04:18:30 +00006440- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006441 PyObject_Call() never calling back out to Python code to trigger
6442 recursion depth updates/checks. Required the creation of a static
6443 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00006461 __*__ attributes. (Some already existed, e.g., __doc__ and
6462 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006463

6472 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006480 setting a plain string, ie don't expand to single letter identifiers.
6481
Raymond Hettinger13936692007-04-11 18:40:58 +00006482- Request #1191699: Slices can now be pickled.

6492
Guido van Rossum143b5642007-03-23 04:58:42 +00006493- Bug #1683368: The object.__init__() and object.__new__() methods are
6494 now stricter in rejecting excess arguments. The only time when
6495 either allows excess arguments is when it is not overridden and the
6496 other one is. For backwards compatibility, when both are
6497 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006498 warning later). Also, type.__init__() insists on the same signature
6499 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006501- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6502 object to complex using its __complex__() method before falling back
6503 to the __float__() method. Therefore, the functions in the cmath
6504 module now can operate on objects that define a __complex__()
6505 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006523- Bug #1678647: write a newline after printing an exception in any
6524 case, even when converting the value to a string failed.
6525
Georg Brandl871f1bc2007-03-12 13:17:36 +00006526- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006527 its argument, if it exists. If not, it will work like before. This
6528 allows customizing the output of dir() in the presence of a
6529 __getattr__().

6539 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006540
Georg Brandlaa2321b2007-03-07 00:40:28 +00006541- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006542 makes the filenames the warning module prints much more sensible
6543 when a PYTHONSTARTUP file is used.

6557 sq_ass_slice instead of the sq_slice slot.
6558
Georg Brandl3ee81df2008-05-17 18:14:43 +00006559- When printing an unraisable error, don't print exceptions. before

7188 incompatibility since it never made sense with ordinary subclasses
7189 -- the failure just occurred later, with a more cumbersome
7190 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007471- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7472 with RFC 3207 and forgets any knowledge obtained from the server not
7473 obtained from the TLS negotiation itself. Patch contributed by Bill
7474 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007475
Georg Brandl3ee81df2008-05-17 18:14:43 +00007476- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007477 that the SMTP.starttls() caller no longer needs to call ehlo()
7478 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007479 does not claim to support starttls. Adds the
7480 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7561 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7562 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007579 time so that opening a database previously created with the DB_DUP
7580 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7581 opens. Specifically: dictionary assignment to a DB object will
7582 replace all values for a given key when the database allows
7583 duplicate values. DB users should use DB.put(k, v) when they want
7584 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007585

7591 characters with ASCII value less than 32. Also, it correctly quotes
7592 dots only if they occur on a single line, as opposed to the previous
7593 behavior of quoting dots if they are the second character of any
7594 line.

7917-----
7918
Georg Brandl3ee81df2008-05-17 18:14:43 +00007919- Unified naming convention for free lists and their limits. All free
7920 lists in Object/ are named ``free_list``, the counter ``numfree``
7921 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7922 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007923
Georg Brandl3ee81df2008-05-17 18:14:43 +00007924- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7925 to ``PyTuple_SetItem``, it can be used to populate a brand new
7926 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007927
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007928- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007929
Georg Brandl3ee81df2008-05-17 18:14:43 +00007930- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7931 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7932 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007933
7934- Patch #1720595: add T_BOOL to the range of structmember types.
7935
7936- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7937 ``PyFloat_GetInfo()`` to the float API.
7938
Georg Brandl3ee81df2008-05-17 18:14:43 +00007939- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7940 of w# format code incorrectly truncated the length to an int, even
7941 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7942 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007943
Georg Brandl3ee81df2008-05-17 18:14:43 +00007944- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7945 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007946
Georg Brandl3ee81df2008-05-17 18:14:43 +00007947- PEP 3123: Provide forward compatibility with Python 3.0, while
7948 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7949 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007950
Georg Brandl3ee81df2008-05-17 18:14:43 +00007951- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7952 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007953
7954- Patch #1733960: Allow T_LONGLONG to accept ints.
7955
7956- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7957
Christian Heimes000a0742008-01-03 22:16:32 +00007958- Added a new API function ``PyImport_ImportModuleNoBlock``.
7959
Georg Brandl6caad7d2008-01-26 14:19:22 +00007960- Bug #1637022: Prefix AST symbols with _Py_.
7961
7962- Fix some leftovers from the conversion from int to Py_ssize_t
7963 (relevant to strings and sequences of more than 2**31 items).
7964
7965- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7966 outside of pystate.c and should not be necessary.
7967
Georg Brandl3ee81df2008-05-17 18:14:43 +00007968- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7969 absolute imports. In earlier versions they might have used relative
7970 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007971
Georg Brandl3ee81df2008-05-17 18:14:43 +00007972- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7973 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007974
Georg Brandl3ee81df2008-05-17 18:14:43 +00007975- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7976 macro so it can be used as an expression.

7981
Georg Brandl3ee81df2008-05-17 18:14:43 +00007982- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7983 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7984 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7985 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007986
Georg Brandl3ee81df2008-05-17 18:14:43 +00007987- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
7988 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008000- Removed the macfs module. It had been deprecated since Python 2.5.
8001 This lead to the deprecation of macostools.touched() as it relied
8002 solely on macfs and was a no-op under OS X.
