20 is modified during the lifetime of the Python process after zipimport has
21 already cached the zip's table of contents we detect this and recover
22 rather than read bad data from the .zip (causing odd import errors).

34 contains a frame, and the frame kept a reference to the Python state of the

591
Ned Deily0203a802013-10-25 00:40:07 -0700592- Issue #15663: Tcl/Tk 8.5.15 is now included with the OS X 10.6+
593 64-bit/32-bit installer for 10.6+. It is no longer necessary
594 to install a third-party version of Tcl/Tk 8.5 to work around the
595 problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
596 and later releases.

Ned Deilyf84b5312013-10-25 00:44:46 -0700598- Issue #19019: Change the OS X installer build script to use CFLAGS instead
599 of OPT for special build options. By setting OPT, some compiler-specific
600 options like -fwrapv were overridden and thus not used, which could result
601 in broken interpreters when building with clang.

1648 In particular, fix extension module build failures when trying to use
1649 32-bit-only installer Pythons on systems with Xcode 4 (currently
1650 OS X 10.8, 10.7, and optionally 10.6).
1651 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1652 * Since Xcode 4 removes ppc support, extension module builds now
1653 check for ppc compiler support and by default remove ppc and
1654 ppc64 archs when they are not available.
1655 * Extension module builds now revert to using system installed
1656 headers and libs (/usr and /System/Library) if the SDK used
1657 to build the interpreter is not installed or has moved.
1658 * Try to avoid building extension modules with deprecated
1659 and problematic Apple llvm-gcc compiler. If original compiler
1660 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002084- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002085 has left two versions of customize_compiler, the original in
2086 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002091- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2092 Distutils-based packages with C extension modules may fail because
2093 Apple has removed gcc-4.2, the version used to build python.org
2094 64-bit/32-bit Pythons. If the user does not explicitly override
2095 the default C compiler by setting the CC environment variable,
2096 Distutils will now attempt to compile extension modules with clang
2097 if gcc-4.2 is required but not found. Also as a convenience, if
2098 the user does explicitly set CC, substitute its value as the default
2099 compiler in the Distutils LDSHARED configuration variable for OS X.
2100 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2101 SDK, neither of which are available in Xcode 4. This change does not
2102 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002352- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2353 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2354 interpreter process. This could cause failures in non-Distutils subprocesses
2355 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002356 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002357 deployment target only in the environment of each build subprocess. It is
2358 still possible to globally override the default by setting
2359 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2360 greater or equal to the default value, the value with which the interpreter
2361 was built.

2391 the ticker doesn't have to wind down to zero from the old starting point
2392 before the new interval takes effect. And if the user increases the
2393 interval, it makes sure the new limit takes effect right away rather have an
2394 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00003219- Issue #9869: Make long() and PyNumber_Long return something of type
3220 long for a class whose __long__ method returns a plain int. This
3221 fixes an interpreter crash when initializing an instance of a long
3222 subclass from an object whose __long__ method returns a plain int.

3227 thread-local storage key.
3228
Victor Stinnercaafd772010-09-08 10:51:01 +00003229- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
3230 encoding and errors attributes instead of using utf-8 in strict mode, to get
3231 the same behaviour than the print statement.
3232
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00003233- Issue #9737: Fix a crash when trying to delete a slice or an item from

3246 output with no type specifier failed to match the str output:
3247
3248 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3249 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
3250

3345 received. Now sendall() properly calls signal handlers if necessary,
3346 and retries sending if these returned successfully, including on sockets

3358 handles non-blocking readinto() returning None correctly.
3359

3361 SSLSocket.sendto() to match the corresponding socket methods. Also,
3362 fix various SSLSocket methods to raise socket.error rather than an
3363 unhelpful TypeError when called on an unconnected socket. Original patch
3364 by Andrew Bennetts.
3365
Raymond Hettinger74f869e2010-09-13 22:14:36 +00003366- Issue #9826: OrderedDict.__repr__ can now handle self-referential
3367 values: d['x'] = d.

3373
Raymond Hettinger20397532010-09-12 02:11:45 +00003374- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3375 This prevents user-created self-referencing ordered dictionaries from
3376 becoming permanently uncollectable GC garbage. The downside is that
3377 removing __del__ means that the internal doubly-linked list has to wait for
3378 GC collection rather than freeing memory immediately when the refcnt drops
3379 to zero.
3380
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003381- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00003382 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003383 value.
3384
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003385- Issue #9792: In case of connection failure, socket.create_connection()
3386 would swallow the exception and raise a new one, making it impossible
3387 to fetch the original errno, or to filter timeout errors. Now the
3388 original error is re-raised.
3389
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003390- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3391 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3392 be updated back after the system call. Original patch by Brian Brazil.
3393
Antoine Pitroudca9de92010-09-04 17:52:26 +00003394- Issue #1100562: Fix deep-copying of objects derived from the list and

3398 ConfigParser.write.
3399
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003400- Issue #808164: Fixed socket.close to avoid references to globals, to
3401 avoid issues when socket.close is called from a __del__ method.
3402
Terry Reedyd2d2ae92010-11-11 23:22:19 +00003403- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

3405 heuristic. Patch by Terry Reedy and Eli Bendersky
3406
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003407- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3408 falling into recursion.
3409
R. David Murray7c4bf552010-08-25 01:45:57 +00003410- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3411 character years even if the message contains RFC822 two character years.
3412
Daniel Stutzbach91287322010-08-24 21:09:30 +00003413- Issue #8750: Fixed MutableSet's methods to correctly handle

3423
Raymond Hettinger917bba12010-08-22 08:01:58 +00003424- Issue #9214: Set operations on KeysView or ItemsView in the collections
3425 module now correctly return a set. (Patch by Eli Bendersky.)
3426
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003427- Issue #9617: Signals received during a low-level write operation aren't
3428 ignored by the buffered IO layer anymore.
3429
Benjamin Peterson52c36052010-08-21 03:03:22 +00003430- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3431 are not held onto after they are deleted elsewhere.
3432
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003433- Issue #9626: the view methods for collections.OrderedDict() were returning
3434 the unordered versions inherited from dict. Those methods are now
3435 overridden to provide ordered views.
3436
Éric Araujo0389ae62010-08-14 03:07:46 +00003437- Issue #8688: MANIFEST files created by distutils now include a magic
3438 comment indicating they are generated. Manually maintained MANIFESTs
3439 without this marker will not be overwritten or removed.
3440
Antoine Pitroue1436d12010-08-12 15:25:51 +00003441- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3442 and a BadZipfile error is raised if it doesn't match (as used to be the
3443 case in Python 2.5 and earlier).
3444
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003445- Issue #9550: a BufferedReader could issue an additional read when the
3446 original read request had been satisfied, which could block indefinitely
3447 when the underlying raw IO channel was e.g. a socket. Report and original
3448 patch by Jason V. Miller.
3449
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003450- Issue #9551: Don't raise TypeError when setting the value to None for

3466 PROT_WRITE and PROT_EXEC.
3467
Senthil Kumarane677ecf2010-08-08 11:56:31 +00003468- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
3469 This is how it is supposed to work, wget and curl do the same. Previous
3470 behavior was wrong.
3471
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +00003472- Issue #2944: asyncore doesn't handle connection refused correctly.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003837- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3838 start byte and the continuation byte(s) are now considered invalid, instead
3839 of the number of bytes specified by the start byte.
3840 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3841 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3842 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3843 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003851- Issue #8748: Fix two issues with comparisons between complex and integer
3852 objects. (1) The comparison could incorrectly return True in some cases
3853 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3854 (2) The comparison raised an OverflowError for large integers, leading
3855 to unpredictable exceptions when combining integers and complex objects
3856 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003858- Issue #5211: Implicit coercion for the complex type is now completely
3859 removed. (Coercion for arithmetic operations was already removed in 2.7
3860 alpha 4, but coercion for rich comparisons was accidentally left in.)
3861
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003862- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00004049- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4050 operation raises multiple signals and more than one of those signals is
4051 trapped, the specification determines the order in which the signals should be

4239 with a non-empty format string. This is an effort to future-proof user
4240 code. If a derived class does not currently implement __format__ but later
4241 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004242 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004243 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004276- Issue #8257: The Decimal construct now accepts a float instance directly,
4277 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004278
4279 >>> Decimal(1.1)
4280 Decimal('1.100000000000000088817841970012523233890533447265625')
4281

Georg Brandlfee0f442010-05-22 21:26:21 +00004293- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4294 InvalidOperation instead of returning False. (Comparisons involving a quiet
4295 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4296 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00004298- Issue #2531: Comparison operations between floats and Decimal instances now
4299 return a result based on the numeric values of the operands; previously they
4300 returned an arbitrary result based on the relative ordering of id(float) and
4301 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004303- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004304 argument `-` which tells it to read files to compile from stdin. Each line is
4305 read on demand and the named file is compiled immediately. (Original patch by
4306 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00004315- Comparisons using one of <, <=, >, >= between a complex instance and a
4316 Fractions instance now raise TypeError instead of returning True/False. This
4317 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4318 <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004417- Issue #8300: When passing a non-integer argument to struct.pack with any
4418 integer format code, struct.pack first attempts to convert the non-integer

4421
Georg Brandlba83f822010-03-14 09:50:54 +00004422- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4423 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4424 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004425 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4426 inconsistent: __int__ was used for some integer codes but not for others, and
4427 the set of integer codes for which it was used differed between native packing
4428 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004740- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4741 class used to represent files stored inside an archive. The new
4742 implementation is significantly faster and can be wrapped in a
4743 ``io.BufferedReader`` object for more speedups. It also solves an issue
4744 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004835- The ``__complex__()`` method is now looked up on the class of instances to
4836 make it consistent with other special methods.

4840
Mark Dickinson1b34d252010-01-01 17:27:30 +00004841- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004842 DeprecationWarning when passed a float argument where an integer was expected.
4843 These functions and methods now raise TypeError instead. The majority of the
4844 effects of this change are in the extension modules, but some core functions
4845 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4846 and many unicode/str methods.

4861 least on IEEE 754 platforms), and in particular does not depend on the
4862 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00005010- Issue #3382: 'F' formatting for float and complex now convert the result to
5011 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5012 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005013
Georg Brandlba83f822010-03-14 09:50:54 +00005014- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5015 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005016
Georg Brandlba83f822010-03-14 09:50:54 +00005017- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5018 1e-100 used to raise OverflowError, but now gives the requested 120
5019 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00005028- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5029 decimal string that's guaranteed to round back to x under correct rounding
5030 (with round-half-to-even rounding mode). Previously it gave a string based on
5031 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5032 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5033 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005034
Georg Brandlba83f822010-03-14 09:50:54 +00005035- Issue #7117: On almost all platforms: float-to-string and string-to-float
5036 conversions within Python are now correctly rounded. Places these conversions
5037 occur include: str for floats and complex numbers; the float and complex
5038 constructors; old-style and new-style numeric formatting; serialization and
5039 deserialization of floats and complex numbers using marshal, pickle and json;
5040 parsing of float and imaginary literals in Python code; Decimal-to-float
5041 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005042
Georg Brandlba83f822010-03-14 09:50:54 +00005043 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5044 providing correctly-rounded strtod and dtoa C functions. This code is
5045 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5046 the C compiler. There may be a small number of platforms on which correct
5047 operation of this code cannot be guaranteed, so the code is not used: notably,
5048 this applies to platforms where the C double format is not IEEE 754 binary64,
5049 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5050 and Python's configure script is unable to determine how to change the FPU
5051 precision. On these platforms conversions use the platform strtod and dtoa,
5052 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005054- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5055 uses the correctly-rounded string <-> float conversions described above (when
5056 available), and so produces correctly rounded results that will display nicely
5057 under the float repr. There are two related small changes: (1) round now
5058 accepts any class with an ``__index__()`` method for its second argument (but
5059 no longer accepts floats for the second argument), and (2) an excessively
5060 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5061 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005208- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5209 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5210 but with at least one decimal point and with a default precision
5211 of 12. Previously, the behavior the same but with a default precision of 6.
5212 This more closely matches ``str()``, and reduces surprises when adding
5213 alignment flags to the empty presentation type. This also affects the new
5214 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00006703 leak-chasing test runs give sensible results. The previous method of reaping
6704 threads could return successfully while some Thread objects were still

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006845- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6846
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006847- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6848 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6849 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6850 ``printf`` function, whereas PyString_FromFormat has an independent
6851 implementation and uses "%zd" on all platforms for size_t values.
6852 This makes a difference on win64, where ``printf`` needs "%Id" to display
6853 64bit values.
6854
Benjamin Peterson97179b02008-09-09 20:55:01 +00006855- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6856 error.
6857
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006858- Issue #3777: long() applied to a float object now always return a long
6859 object; previously an int would be returned for small values. the __long__
6860 method is allowed to return either an int or a long, but the behaviour of
6861 float objects should not change to respect backward compatibility.
6862
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006863- Issue #3751: str.rpartition would perform a left-partition when called with
6864 a unicode argument.
6865
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006866- Issue #3683: Fix compilation when --without-threads is given.
6867
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006868- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006869 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006870 was correctly parsed but parsing of subsequent arguments failed.
6871
Vinay Sajip35e3b032008-09-01 14:33:59 +00006872- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006873 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6874 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6875 when given a tuple of classes as second argument, were looking up
6876 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6877 type object.
6878
Neal Norwitz18aa3882008-08-24 05:04:52 +00006879- Fix crashes on memory allocation failure found with failmalloc.
6880
6881- Fix memory leaks found with valgrind and update suppressions file.
6882
6883- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6884
6885- Fix problem using wrong name in decimal module reported by pychecker.
6886
Christian Heimes7d4c3172008-08-22 19:47:25 +00006887- Silenced another compiler warning about a used but not defined
6888 function 'stringlib_contains_obj'.
6889
Benjamin Peterson712ee922008-08-24 18:10:20 +00006890- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6891 ``__delslice__``.

6894 library targets in the Makefile.
6895
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006896- Issue #1204: The configure script now tests for additional libraries
6897 that may be required when linking against readline. This fixes issues
6898 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00006948 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6949 for catch_warnings() also led to an improvement in the raising of a
6950 DeprecationWarning related to warnings.warn_explicit().
6951
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006952- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007016What's New in Python 2.6 beta 3?
7017================================
7018
Barry Warsaw07a4a382008-08-21 01:15:08 +00007019*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007020
7021Core and Builtins
7022-----------------
7023
Guido van Rossumf8402962008-08-20 15:01:50 +00007024- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7025 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7026 extensions do not automatically benefit from the class attribute
7027 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7028 to their tp_flags field if they care. This is a backwards
7029 compatibility feature; in 3.0, all types will use the cache by
7030 default.
7031
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007032- Keyword arguments can now follow starred arguments. (``f(a, *args,
7033 keyword=23)`` is now valid syntax.)
7034
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007035- ctypes function pointers that are COM methods have a boolean True
7036 value again.
7037
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007038- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7039 by denying s# to parse objects that have a releasebuffer procedure,
7040 and introducing s*.
7041
Georg Brandl1e13ea92008-08-11 09:07:59 +00007042- Issue #3537: Fix an assertion failure when an empty but presized dict
7043 object was stored in the freelist.
7044
Mark Dickinsonb6467572008-08-04 21:30:09 +00007045- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7046 ValueError consistently across platforms.
7047
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007048- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7049 (64bit Unix, for example), unichr() would truncate its argument and return
7050 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7051
Neal Norwitze7d8be82008-07-31 17:17:14 +00007052- Apply security patches from Apple.
7053
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007054- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7055 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7056
Antoine Pitrou92f82162008-07-25 22:22:08 +00007057- Issue #1819: function calls with several named parameters are now on
7058 average 35% faster (as measured by pybench).
7059
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007060- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7061 the python debugger steps into a class statement: the free variables (local
7062 variables defined in an outer scope) would be deleted from the outer scope.
7063
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007064- Issue #2620: Overflow checking when allocating or reallocating memory
7065 was not always being done properly in some python types and extension
7066 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7067 all been updated to perform better checks and places in the code that
7068 would previously leak memory on the error path when such an allocation
7069 failed have been fixed.

7077 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7078
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007079- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7080 version reported by these tools does not necessarily follow the python
7081 version numbering scheme, so the module is less strict when parsing it.
7082
Nick Coghlanf70385a2008-08-18 12:42:46 +00007083- Issue #2235: Added Py3k warnings for types which will become unhashable
7084 under the stricter __hash__ inheritance rules in 3.0. Several types
7085 which did not meet the rules for hash invariants and were already
7086 unhashable in 3.0 have now been explicitly flagged as unhashable in
7087 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7088 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7089
Brett Cannon88f801d2008-08-18 00:46:22 +00007090- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7091 imported into the module but exposed as part of the module's API.
7092

7098
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007099- Issue #3575: Incremental decoder's decode function now takes bytearray
7100 by using 's*' instead of 't#'.
7101
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007102- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007103 fails unicode conversion on 2nd parameter. (windows only)
7104
Georg Brandl222e2082010-08-01 22:27:39 +00007105- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007106 in a redirect.
7107

Brett Cannon721b1452008-08-16 22:00:27 +00007109 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007110
Facundo Batistaeb90b782008-08-16 14:44:07 +00007111- Issue #2776: fixed small issue when handling an URL with double slash
7112 after a 302 response in the case of not going through a proxy.
7113
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007114- Issue #2676: in the email package, content-type parsing was hanging on
7115 pathological input because of quadratic or exponential behaviour of a
7116 regular expression.
7117
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007118- Issue #3476: binary buffered reading through the new "io" library is now

7122 since mimetools itself is deprecated. Because modules are cached, all
7123 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

Antoine Pitroude781a42008-08-09 12:43:23 +00007159 asking for a specific length. This problem only affected files opened

7203
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007204- Issue #643841: The language reference now provides more detailed

7217
Georg Brandl3e483f62008-07-16 22:57:41 +00007218- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7219 its methods now allow for items objects that can be converted to
7220 an integer using operator.index().
7221
Mark Dickinson64b7e502008-07-16 09:40:03 +00007222- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7223 produced a ValueError instead of giving the correct float.
7224
Eric Smitha5fa5a22008-07-16 00:11:49 +00007225- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7226 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7227
Mark Dickinson7103aa42008-07-15 19:08:33 +00007228- Issue #3008: the float type has a new instance method 'float.hex'
7229 and a new class method 'float.fromhex' to convert floating-point
7230 numbers to and from hexadecimal strings, respectively.
7231
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007232- Issue #2235: __hash__ is once again inherited by default. To allow
7233 collections.Hashable to remain meaningful in the presence of the
7234 default hash implementation (object.__hash__), it is now possible
7235 to explicit block inheritance of hash by setting __hash__=None at
7236 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7237 level.
7238
Nick Coghlanb028f502008-07-13 14:52:36 +00007239- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7240 the parent module cannot be found while performing an absolute import.
7241 This means that an incorrectly defined __package__ attribute will
7242 now only prevent relative imports in that module rather than causing
7243 all imports from that module to fail.
7244
Nick Coghlan14ff9942008-07-08 14:21:42 +00007245- Issue #2517: Allow unicode messages in Exceptions again by correctly

7255 another thread's dictionary.
7256
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007257- Issue #3004: Minor change to slice.indices(): the start and stop
7258 arguments are now treated identically, making the behaviour easier
7259 to describe and understand. For example, slice(None, -10,
7260 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7261 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7262 10, -1).
7263
Georg Brandl278fc502008-07-19 12:46:12 +00007264- Issue #3219: Calling a function with repeated keyword arguments,
7265 f(a=2, a=23), would not cause a syntax error. This was a regression
7266 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00007268- Issue #2862: Make int and float freelist management consistent with
7269 other freelists. Changes their CompactFreeList apis into

7276 api functions without holding the GIL, which could lead to a fatal
7277 error when they failed.
7278
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007279- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007304- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7305 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007306 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007307 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007323- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Vinay Sajip9828b7e2008-06-17 11:04:02 +00007692- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007693 environment to control the '-arch' flags that are used to build
7694 an extension. This was added for compatibility with Apple's build
7695 of Python.
7696
7697- The bundled OSX-specific copy of libbffi is now in sync with the version
7698 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.

7709
Brett Cannonb61d8012008-05-11 23:39:04 +00007710- ``Lib/lib-old`` is now added to sys.path.
7711
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007712- On MacOS X it is now possible to install the framework in 64-bit
7713 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007714 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007715
7716 This is controlled by the configure argument ``--with-universal-archs``:
7717
7718 - ``--with-universal-archs=all``: install 4-way universal
7719
7720 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7721
7722 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7723
7724 This option should be used in combination with ``--enable-universalsdk=``.
7725
7726 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 +00007775- Issue #1631171: Re-implement the 'warnings' module in C (the
7776 original Python code has been kept as backup). This will allow for
7777 using the 'warning's machinery in such places as the parser where
7778 use of pure Python code is not possible. Both the ``showarning()``
7779 and ``formatwarning()`` gain an optional 'line' argument which is
7780 not called by default for backwards-compatibility reasons. Setting
7781 ``warnings.showwarning()`` to an implementation that lacks support
7782 for the ``line`` argument will raise a DeprecationWarning.

7806
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007807- The getpass module has been improved on Unix. It now uses /dev/tty
7808 by default and uses stderr instead of stdout. A GetPassWarning is
7809 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007824- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007825 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007845- Issue #2550: The approach used by client/server code for obtaining
7846 ports to listen on in network-oriented tests has been refined in an
7847 effort to facilitate running multiple instances of the entire
7848 regression test suite in parallel without issue.
7849 test_support.bind_port() has been fixed such that it will always
7850 return a unique port -- which wasn't always the case with the
7851 previous implementation, especially if socket options had been set
7852 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7853 new implementation of bind_port() will actually raise an exception
7854 if it is passed an AF_INET/SOCK_STREAM socket with either the
7855 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7856 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7857 the socket it's been passed. This currently only applies to
7858 Windows. This option prevents any other sockets from binding to the
7859 host/port we've bound to, thus removing the possibility of the
7860 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7861 when a second SOCK_STREAM socket binds and accepts to a host/port
7862 that's already been bound by another socket. The optional preferred
7863 port parameter to bind_port() has been removed. Under no
7864 circumstances should tests be hard coding ports!
7865
7866 test_support.find_unused_port() has also been introduced, which will
7867 pass a temporary socket object to bind_port() in order to obtain an
7868 unused port. The temporary socket object is then closed and
7869 deleted, and the port is returned. This method should only be used
7870 for obtaining an unused port in order to pass to an external program
7871 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7872 a parameter to a server-oriented class that doesn't give you direct
7873 access to the underlying socket used.
7874
7875 Finally, test_support.HOST has been introduced, which should be used
7876 for the host argument of any relevant socket calls (i.e. bind and
7877 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007878
7879 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007880 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007881 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7882 test_asynchat and test_socket_ssl.
7883
Georg Brandl3ee81df2008-05-17 18:14:43 +00007884 It is now possible for multiple instances of the regression test
7885 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008164- Added the future_builtins module, which contains hex() and oct().
8165 These are the PEP 3127 version of these functions, designed to be
8166 compatible with the hex() and oct() builtins from Python 3.0. They
8167 differ slightly in their output formats from the existing, unchanged
8168 Python 2.6 builtins. The expected usage of the future_builtins
8169 module is:
8170 from future_builtins import hex, oct
8171
Eric Smith7ef40bf2008-02-20 23:34:22 +00008172- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8173 exponents for exponents with absolute value < 100. Follows C99
8174 standard. This is a change on Windows, which would use 3 digits.
8175 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8176 so that any alterations it does to the resulting string will be
8177 available in stringlib/formatter.h (for float.__format__).
8178
Eric Smith5a3c1352008-02-19 13:21:56 +00008179- Implemented PEP 3101, Advanced String Formatting. This adds a new
8180 builtin format(); a format() method for str and unicode; a
8181 __format__() method to object, str, unicode, int, long, float, and
8182 datetime; the class string.Formatter; and the C API
8183 PyObject_Format().
8184
Georg Brandl3ee81df2008-05-17 18:14:43 +00008185- Fixed several potential crashes, all caused by specially crafted
8186 __del__ methods exploiting objects in temporarily inconsistent
8187 state.

8197 in order to allow pymalloc to free more arenas. Python may give back
8198 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008199
Georg Brandl3ee81df2008-05-17 18:14:43 +00008200- Issue #2045: Fix an infinite recursion triggered when printing a
8201 subclass of collections.defaultdict, if its default_factory is set
8202 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008203
Christian Heimesf75dbef2008-02-08 00:11:31 +00008204- Fixed a minor memory leak in dictobject.c. The content of the free
8205 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00008207- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008208 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008209
Georg Brandl3ee81df2008-05-17 18:14:43 +00008210- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8211 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008212 to compact the internal free lists of pre-allocted ints and floats.
8213
Georg Brandl3ee81df2008-05-17 18:14:43 +00008214- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8215 calls. Python expected the return type int but the fork familie
8216 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008217
Georg Brandl3ee81df2008-05-17 18:14:43 +00008218- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8219 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008220
Georg Brandl3ee81df2008-05-17 18:14:43 +00008221- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8222 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008223
Georg Brandl3ee81df2008-05-17 18:14:43 +00008224- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8225 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00008227- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8228 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008229
Georg Brandl3ee81df2008-05-17 18:14:43 +00008230- Patch #1473257: generator objects gain a gi_code attribute. This is
8231 the same object as the func_code attribute of the function that
8232 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008233
Georg Brandl3ee81df2008-05-17 18:14:43 +00008234- Issue #1920: "while 0" statements were completely removed by the
8235 compiler, even in the presence of an "else" clause, which is
8236 supposed to be run when the condition is false. Now the compiler
8237 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008238
Guido van Rossumeead05f2008-01-24 18:21:02 +00008239- A few crashers fixed: weakref_in_del.py (issue #1377858);
8240 loosing_dict_ref.py (issue #1303614, test67.py);
8241 borrowed_ref_[34].py (not in tracker).
8242
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008243- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008244 suppressed while an extension is loaded by calling SetErrorMode in
8245 dynload_win.c. The error is still reported properly.
8246
Georg Brandl3ee81df2008-05-17 18:14:43 +00008247- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008248 several extension methods and modules do not work without unicode
8249 support.
8250
Georg Brandl26543b12008-01-21 18:36:51 +00008251- Issue #1882: when compiling code from a string, encoding cookies in the
8252 second line of code were not always recognized correctly.
8253
Georg Brandl14404b62008-01-19 19:27:05 +00008254- Issue #1679: "0x" was taken as a valid integer literal.
8255
Georg Brandl6caad7d2008-01-26 14:19:22 +00008256- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008257 added.
8258
Christian Heimesc94e2b52008-01-14 04:13:37 +00008259- sys.float_info / PyFloat_GetInfo: The floating point information
8260 object was converted from a dict to a specialized structseq object.
8261
Georg Brandl3ee81df2008-05-17 18:14:43 +00008262- Patch #1816: Added sys.flags structseq. It exposes the status of
8263 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008264
Georg Brandl3ee81df2008-05-17 18:14:43 +00008265- Objects/structseq.c: Implemented new structseq representation. The
8266 patch makes structseqs (e.g. the return value of os.stat) more
8267 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008268
Georg Brandl3ee81df2008-05-17 18:14:43 +00008269- Patch #1700288: added a type attribute cache that caches method
8270 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008271
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008272- Bug #1776: __import__() no longer accepts filenames on any platform.
8273 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008274
Georg Brandlaed6c662008-01-07 17:25:53 +00008275- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8276
Georg Brandl3ee81df2008-05-17 18:14:43 +00008277- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8278 envvar and sys.dont_write_bytecode attribute. All these can be set
8279 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008280
Georg Brandl3ee81df2008-05-17 18:14:43 +00008281- Improve some exception messages when Windows fails to load an
8282 extension module. Now we get for example '%1 is not a valid Win32
8283 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008284
Georg Brandl3ee81df2008-05-17 18:14:43 +00008285- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008287- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8288 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008289
Christian Heimes0a8143f2007-12-18 23:22:54 +00008290- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008291 and INF. float("nan"), float("inf") and float("-inf") now work on
8292 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008293
Georg Brandl3ee81df2008-05-17 18:14:43 +00008294- Compiler now generates simpler and faster code for dictionary
8295 literals. The oparg for BUILD_MAP now indicates an estimated
8296 dictionary size. There is a new opcode, STORE_MAP, for adding
8297 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008298
Georg Brandl3ee81df2008-05-17 18:14:43 +00008299- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008304- Issue #1538: Avoid copying string in split/rsplit if the split char
8305 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008306
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008307- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008308 SystemError.
8309
Nick Coghlanef01d822007-12-03 12:55:17 +00008310- PEP 366: Allow explicit relative imports when executing modules
8311 inside packages with the -m switch via a new module level
8312 __package__ attribute.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008326- Patch #1739468: Directories and zipfiles containing a __main__.py
8327 file can now be directly executed by passing their name to the
8328 interpreter. The directory/zipfile is automatically inserted as the
8329 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008330
Georg Brandl3ee81df2008-05-17 18:14:43 +00008331- Issue #1265: Fix a problem with sys.settrace, if the tracing
8332 function uses a generator expression when at the same time the
8333 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008334
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008335- sets and frozensets now have an isdisjoint() method.
8336
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008337- optimize the performance of builtin.sum().
8338
Neal Norwitz44f326e2007-10-05 05:29:17 +00008339- Fix warnings found by the new version of the Coverity checker.
8340
Georg Brandl21e99f42010-03-07 15:23:59 +00008341- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008342 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8343 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008344
Georg Brandl3ee81df2008-05-17 18:14:43 +00008345- Issue #1686386: Tuple's tp_repr did not take into account the
8346 possibility of having a self-referential tuple, which is possible
8347 from C code. Nor did object's tp_str consider that a type's tp_str
8348 could do something that could lead to an inifinite recursion.
8349 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8350 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008351
Georg Brandl3ee81df2008-05-17 18:14:43 +00008352- Issue #1164: It was possible to trigger deadlock when using the
8353 'print' statement to write to a file since the GIL was not released
8354 as needed. Now PyObject_Print() does the right thing along with
8355 various tp_print implementations of the built-in types and those in
8356 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008357
Georg Brandl3ee81df2008-05-17 18:14:43 +00008358- Issue #1147: Exceptions were directly allowing string exceptions in
8359 their throw() method even though string exceptions no longer
8360 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008361
Georg Brandl3ee81df2008-05-17 18:14:43 +00008362- Issue #1096: Prevent a segfault from getting the repr of a very
8363 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008364
Brett Cannon1e534b52007-09-07 04:18:30 +00008365- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008366 PyObject_Call() never calling back out to Python code to trigger
8367 recursion depth updates/checks. Required the creation of a static
8368 RuntimeError instance in case normalizing an exception put the
8369 recursion check value past its limit. Fixes crashers
8370 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008371
Georg Brandl3ee81df2008-05-17 18:14:43 +00008372- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008385- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008386 __*__ attributes. (Some already existed, e.g., __doc__ and
8387 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008388
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008389- Add -3 option to the interpreter to warn about features that are
8390 deprecated and will be changed/removed in Python 3.0.
8391
Georg Brandl2134e752007-05-21 20:34:16 +00008392- Patch #1686487: you can now pass any mapping after '**' in function
8393 calls.
8394
Collin Winter62903052007-05-18 23:11:24 +00008395- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008396 "except E as target:". This is to provide forwards compatibility
8397 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008398
Brett Cannon229cee22007-05-05 01:34:02 +00008399- Deprecate BaseException.message as per PEP 352.
8400
Georg Brandl3ee81df2008-05-17 18:14:43 +00008401- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008402 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008403
Vinay Sajip8549ce32007-05-06 17:53:37 +00008404- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008405 setting a plain string, ie don't expand to single letter identifiers.
8406
Raymond Hettinger13936692007-04-11 18:40:58 +00008407- Request #1191699: Slices can now be pickled.
8408
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008409- Request #1193128: str.translate() now allows a None argument for
8410 translations that only remove characters without re-mapping the
8411 remaining characters.
8412
Georg Brandl5cb76c12007-03-21 09:00:39 +00008413- Patch #1682205: a TypeError while unpacking an iterable is no longer
8414 masked by a generic one with the message "unpack non-sequence".
8415
Neal Norwitzaa754b72007-03-21 06:39:48 +00008416- Remove unused file Python/fmod.c.
8417
Guido van Rossum143b5642007-03-23 04:58:42 +00008418- Bug #1683368: The object.__init__() and object.__new__() methods are
8419 now stricter in rejecting excess arguments. The only time when
8420 either allows excess arguments is when it is not overridden and the
8421 other one is. For backwards compatibility, when both are
8422 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008423 warning later). Also, type.__init__() insists on the same signature
8424 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008425
Georg Brandl3ee81df2008-05-17 18:14:43 +00008426- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8427 object to complex using its __complex__() method before falling back
8428 to the __float__() method. Therefore, the functions in the cmath
8429 module now can operate on objects that define a __complex__()
8430 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008431
Georg Brandl3ee81df2008-05-17 18:14:43 +00008432- Patch #1623563: allow __class__ assignment for classes with

Georg Brandl3ee81df2008-05-17 18:14:43 +00009497 time so that opening a database previously created with the DB_DUP
9498 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9499 opens. Specifically: dictionary assignment to a DB object will
9500 replace all values for a given key when the database allows
9501 duplicate values. DB users should use DB.put(k, v) when they want
9502 to store duplicates; not DB[k] = v.

9509 characters with ASCII value less than 32. Also, it correctly quotes
9510 dots only if they occur on a single line, as opposed to the previous
9511 behavior of quoting dots if they are the second character of any
9512 line.
