1284
1285- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1286 and later systems as is currently done for Python 3.x installers.
1287 For 2.7.7 only, we will provide three installers:
1288 the legacy deprecated 10.3+ 32-bit-only format;
1289 the newer 10.5+ 32-bit-only format;
1290 and the unchanged 10.6+ 64-/32-bit format.
1291 Although binary installers will no longer be available from
1292 python.org as of 2.7.8, it will still be possible to build from
1293 source on 10.3.9 and 10.4 systems if necessary.
1294 See Mac/BuildScript/README.txt for more information.

Ned Deily18fae3f2013-01-31 01:24:55 -08002674- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
2675 In particular, fix extension module build failures when trying to use
2676 32-bit-only installer Pythons on systems with Xcode 4 (currently
2677 OS X 10.8, 10.7, and optionally 10.6).
2678 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2679 * Since Xcode 4 removes ppc support, extension module builds now
2680 check for ppc compiler support and by default remove ppc and
2681 ppc64 archs when they are not available.
2682 * Extension module builds now revert to using system installed
2683 headers and libs (/usr and /System/Library) if the SDK used
2684 to build the interpreter is not installed or has moved.
2685 * Try to avoid building extension modules with deprecated
2686 and problematic Apple llvm-gcc compiler. If original compiler
2687 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01003051- Issue #12973: Fix overflow checks that invoked undefined behaviour in
3052 int.__pow__. These overflow checks were causing int.__pow__ to produce
3053 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01003054 compiler optimizing the check away. Also fix similar overflow checks
3055 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

3068 cleared by the garbage collector. This fixes a segfault when an instance
3069 and its type get caught in a reference cycle, and the instance's
3070 deallocator calls one of the methods on the type (e.g. when subclassing
3071 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunaa1f948b2012-01-24 21:05:10 +01003073- Issue #12501: Remove Py3k warning for callable. callable() is supported

Ned Deily0d0ea482012-02-10 12:59:06 +01003131- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3132 Distutils-based packages with C extension modules may fail because
3133 Apple has removed gcc-4.2, the version used to build python.org
3134 64-bit/32-bit Pythons. If the user does not explicitly override
3135 the default C compiler by setting the CC environment variable,
3136 Distutils will now attempt to compile extension modules with clang
3137 if gcc-4.2 is required but not found. Also as a convenience, if
3138 the user does explicitly set CC, substitute its value as the default
3139 compiler in the Distutils LDSHARED configuration variable for OS X.
3140 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3141 SDK, neither of which are available in Xcode 4. This change does not
3142 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003392- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3393 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3394 interpreter process. This could cause failures in non-Distutils subprocesses
3395 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003396 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003397 deployment target only in the environment of each build subprocess. It is
3398 still possible to globally override the default by setting
3399 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3400 greater or equal to the default value, the value with which the interpreter
3401 was built.

3430 updating the check interval, so if the user decreases the check interval,
3431 the ticker doesn't have to wind down to zero from the old starting point
3432 before the new interval takes effect. And if the user increases the
3433 interval, it makes sure the new limit takes effect right away rather have an
3434 early task switch before recognizing the new interval.

Raymond Hettinger74f869e2010-09-13 22:14:36 +00004423- Issue #9826: OrderedDict.__repr__ can now handle self-referential
4424 values: d['x'] = d.
4425
Victor Stinner8fc843b2010-09-17 23:35:50 +00004426- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
Victor Stinner46287f52010-09-13 20:31:34 +00004427
Antoine Pitroue4195e82010-09-12 14:56:27 +00004428- Issue #9837: The read() method of ZipExtFile objects (as returned by
4429 ZipFile.open()) could return more bytes than requested.
4430
Raymond Hettinger20397532010-09-12 02:11:45 +00004431- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4432 This prevents user-created self-referencing ordered dictionaries from
4433 becoming permanently uncollectable GC garbage. The downside is that
4434 removing __del__ means that the internal doubly-linked list has to wait for
4435 GC collection rather than freeing memory immediately when the refcnt drops
4436 to zero.
4437
Raymond Hettingerffd2a422010-09-10 10:47:22 +00004438- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00004439 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00004440 value.
4441
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004442- Issue #9792: In case of connection failure, socket.create_connection()
4443 would swallow the exception and raise a new one, making it impossible
4444 to fetch the original errno, or to filter timeout errors. Now the
4445 original error is re-raised.
4446
Antoine Pitrouf4f61712010-09-07 16:34:47 +00004447- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
4448 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
4449 be updated back after the system call. Original patch by Brian Brazil.
4450
Antoine Pitroudca9de92010-09-04 17:52:26 +00004451- Issue #1100562: Fix deep-copying of objects derived from the list and

4453

4455 ConfigParser.write.
4456
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00004457- Issue #808164: Fixed socket.close to avoid references to globals, to
4458 avoid issues when socket.close is called from a __del__ method.
4459
Terry Reedyd2d2ae92010-11-11 23:22:19 +00004460- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
4461 can be set to False to turn off the previously undocumented 'popularity'
4462 heuristic. Patch by Terry Reedy and Eli Bendersky
4463
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00004464- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
4465 falling into recursion.
4466
R. David Murray7c4bf552010-08-25 01:45:57 +00004467- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
4468 character years even if the message contains RFC822 two character years.
4469
Daniel Stutzbach91287322010-08-24 21:09:30 +00004470- Issue #8750: Fixed MutableSet's methods to correctly handle

4477 errors.
4478
Vinay Sajip1ddd51f2010-08-23 17:50:30 +00004479- Issue #9501: Fixed logging regressions in cleanup code.
4480

4482 module now correctly return a set. (Patch by Eli Bendersky.)
4483
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00004484- Issue #9617: Signals received during a low-level write operation aren't
4485 ignored by the buffered IO layer anymore.
4486
Benjamin Peterson52c36052010-08-21 03:03:22 +00004487- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
4488 are not held onto after they are deleted elsewhere.
4489
Raymond Hettingera54b2da2010-08-17 19:03:06 +00004490- Issue #9626: the view methods for collections.OrderedDict() were returning
4491 the unordered versions inherited from dict. Those methods are now
4492 overridden to provide ordered views.
4493
Éric Araujo0389ae62010-08-14 03:07:46 +00004494- Issue #8688: MANIFEST files created by distutils now include a magic
4495 comment indicating they are generated. Manually maintained MANIFESTs
4496 without this marker will not be overwritten or removed.
4497
Antoine Pitroue1436d12010-08-12 15:25:51 +00004498- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
4499 and a BadZipfile error is raised if it doesn't match (as used to be the
4500 case in Python 2.5 and earlier).
4501
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00004502- Issue #9550: a BufferedReader could issue an additional read when the
4503 original read request had been satisfied, which could block indefinitely
4504 when the underlying raw IO channel was e.g. a socket. Report and original
4505 patch by Jason V. Miller.
4506
Fred Drake0a1fa0e2010-08-10 13:09:54 +00004507- Issue #9551: Don't raise TypeError when setting the value to None for
4508 SafeConfigParser instances constructed with allow_no_value == True.
4509

4514 Thread-local objects involved in reference cycles will be deallocated
4515 timely by the cyclic GC, even if the underlying thread is still running.

4523 PROT_WRITE and PROT_EXEC.
4524
Senthil Kumarane677ecf2010-08-08 11:56:31 +00004525- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
4526 This is how it is supposed to work, wget and curl do the same. Previous
4527 behavior was wrong.
4528
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +00004529- Issue #2944: asyncore doesn't handle connection refused correctly.

4535 the option character for the added 'h/help' option if prefix_chars
4536 does not contain a '-', instead of raising an error.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004894- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4895 start byte and the continuation byte(s) are now considered invalid, instead
4896 of the number of bytes specified by the start byte.
4897 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4898 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4899 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

4909 objects. (1) The comparison could incorrectly return True in some cases
4910 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4911 (2) The comparison raised an OverflowError for large integers, leading

5053 non-float non-integer argument is now converted to an integer (if possible)
5054 using its __int__ method. Previously, only small arguments were treated this
5055 way; larger arguments (those whose __int__ was outside the range of a C long)

5107 operation raises multiple signals and more than one of those signals is
5108 trapped, the specification determines the order in which the signals should be
5109 handled. In many cases this order wasn't being followed, leading to the wrong

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00005255 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
5256 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's

5277Core and Builtins
5278-----------------
5279
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00005280- Issue #7301: Add environment variable $PYTHONWARNINGS.
5281
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00005282- Issue #8329: Don't return the same lists from select.select when no fds are
5283 changed.
5284
Georg Brandlfee0f442010-05-22 21:26:21 +00005285- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005286 on 64-bit machines. The shift count for either left or right shift is
5287 permitted to be up to sys.maxsize.
5288
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00005289- Ensure that tokenization of identifiers is not affected by locale.
5290
Georg Brandlfee0f442010-05-22 21:26:21 +00005291- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00005292
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00005293- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
5294
Georg Brandlfee0f442010-05-22 21:26:21 +00005295- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5296 with a non-empty format string. This is an effort to future-proof user
5297 code. If a derived class does not currently implement __format__ but later
5298 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005299 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005300 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00005301
Antoine Pitroua57df2c2010-03-31 21:32:15 +00005302- Issue #8268: Old-style classes (not just instances) now support weak

5314
Victor Stinner66644262010-03-10 22:30:19 +00005315- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00005316 (SIGINT). If an error occurs while importing the site module, the error is
5317 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00005318 module.

5332
Georg Brandlfee0f442010-05-22 21:26:21 +00005333- Issue #8257: The Decimal construct now accepts a float instance directly,
5334 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005335
5336 >>> Decimal(1.1)
5337 Decimal('1.100000000000000088817841970012523233890533447265625')
5338
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005339- collections.Counter() now supports a subtract() method.
5340
Georg Brandlfee0f442010-05-22 21:26:21 +00005341- The functools module now has a total_ordering() class decorator to simplify
5342 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00005343
Georg Brandlfee0f442010-05-22 21:26:21 +00005344- The functools module also adds cmp_to_key() as a tool to transition old-style
5345 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00005346
Georg Brandlfee0f442010-05-22 21:26:21 +00005347- Issue #8294: The Fraction constructor now accepts Decimal and float instances
5348 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00005349
Georg Brandlfee0f442010-05-22 21:26:21 +00005350- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5351 InvalidOperation instead of returning False. (Comparisons involving a quiet
5352 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5353 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005354
Georg Brandlfee0f442010-05-22 21:26:21 +00005355- Issue #2531: Comparison operations between floats and Decimal instances now
5356 return a result based on the numeric values of the operands; previously they
5357 returned an arbitrary result based on the relative ordering of id(float) and
5358 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005359
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005360- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005361 argument `-` which tells it to read files to compile from stdin. Each line is
5362 read on demand and the named file is compiled immediately. (Original patch by
5363 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005364
Georg Brandlfee0f442010-05-22 21:26:21 +00005365- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00005368- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5369 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005370 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005371
Georg Brandlfee0f442010-05-22 21:26:21 +00005372- Comparisons using one of <, <=, >, >= between a complex instance and a
5373 Fractions instance now raise TypeError instead of returning True/False. This
5374 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5375 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00005376

5480 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
5481 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00005482 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5483 inconsistent: __int__ was used for some integer codes but not for others, and
5484 the set of integer codes for which it was used differed between native packing
5485 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00005697- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
5698 now also used by regrtest to run all the tests in a temporary directory. The
5699 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
5700 Xicluna who helped with the patch.

Georg Brandlba83f822010-03-14 09:50:54 +00005737- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5738 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5739 returning NULL. The macro now returns a statically allocated empty string
5740 instead.

5750 strings,
5751 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005792- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005793 file position when calling `truncate()`. It would previously change the file
5794 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005795 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5796
Georg Brandlba83f822010-03-14 09:50:54 +00005797- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
5798 class used to represent files stored inside an archive. The new
5799 implementation is significantly faster and can be wrapped in a
5800 ``io.BufferedReader`` object for more speedups. It also solves an issue
5801 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
5802 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00005812- Issue #7748: Since unicode values are supported for some metadata options in
5813 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5814 encoded string for them. This ensures that the upload and register commands
5815 send the correct values to PyPI without any error.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00006084
Georg Brandlba83f822010-03-14 09:50:54 +00006085- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
6086 decimal string that's guaranteed to round back to x under correct rounding
6087 (with round-half-to-even rounding mode). Previously it gave a string based on
6088 rounding x to 17 decimal digits. repr(x) for a complex number behaves
6089 similarly. On platforms where the correctly-rounded strtod and dtoa code is
6090 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006091
Georg Brandlba83f822010-03-14 09:50:54 +00006092- Issue #7117: On almost all platforms: float-to-string and string-to-float
6093 conversions within Python are now correctly rounded. Places these conversions
6094 occur include: str for floats and complex numbers; the float and complex
6095 constructors; old-style and new-style numeric formatting; serialization and
6096 deserialization of floats and complex numbers using marshal, pickle and json;
6097 parsing of float and imaginary literals in Python code; Decimal-to-float
6098 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006099
Georg Brandlba83f822010-03-14 09:50:54 +00006100 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6101 providing correctly-rounded strtod and dtoa C functions. This code is
6102 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6103 the C compiler. There may be a small number of platforms on which correct
6104 operation of this code cannot be guaranteed, so the code is not used: notably,
6105 this applies to platforms where the C double format is not IEEE 754 binary64,
6106 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6107 and Python's configure script is unable to determine how to change the FPU
6108 precision. On these platforms conversions use the platform strtod and dtoa,
6109 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00006111- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6112 uses the correctly-rounded string <-> float conversions described above (when
6113 available), and so produces correctly rounded results that will display nicely
6114 under the float repr. There are two related small changes: (1) round now
6115 accepts any class with an ``__index__()`` method for its second argument (but
6116 no longer accepts floats for the second argument), and (2) an excessively
6117 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6118 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00006261 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
6262 (2) parsing of strings representing infinities and nans was locale aware; and
6263 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00006265- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6266 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6267 but with at least one decimal point and with a default precision
6268 of 12. Previously, the behavior the same but with a default precision of 6.
6269 This more closely matches ``str()``, and reduces surprises when adding
6270 alignment flags to the empty presentation type. This also affects the new
6271 complex.__format__ in the same way.
6272
6273- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

6404 collecting the oldest generation) so that allocating lots of objects without

6410
Georg Brandlba83f822010-03-14 09:50:54 +00006411- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
6412 existing .py counterpart, override the co_filename attributes of all code
6413 objects if the original filename is obsolete (which can happen if the file has
6414 been renamed, moved, or if it is accessed through different paths). Patch by
6415 Ziga Seilnacht and Jean-Paul Calderone.

Georg Brandl6425a2f2008-12-28 11:54:53 +00006434- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00006435 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.

Georg Brandlba83f822010-03-14 09:50:54 +00006454- Issue #4445: Replace ``sizeof(PyStringObject)`` with
6455 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
6456 instances. On a typical machine this saves 3 bytes of memory (on average) per
6457 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00006459- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

6461 instead of throwing a MemoryError.
6462
Georg Brandlba83f822010-03-14 09:50:54 +00006463- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00006466- Issue #4367: Python would segfault during compiling when the unicodedata

6468
Georg Brandlba83f822010-03-14 09:50:54 +00006469- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6470 file objects with closefd=False. The file descriptor is still kept open but
6471 the file object behaves like a closed file. The ``FileIO`` object also got a
6472 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00006474- Issue #4348: Some bytearray methods returned that didn't cause any change to
6475 the bytearray, returned the same bytearray instead of a copy.
6476

6491
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00006492- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00006493 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00006495- On windows, ``os.chdir()`` given unicode was not working if
6496 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6497 this code path is really executed because I cannot move to such directory on
6498 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006500- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6501 element is temporarily replaced with an equivalent frozenset. But the
6502 eventual KeyError would always report the empty ``frozenset()`` as the missing
6503 key. Now it correctly refers to the initial element.

6521 returned them on 64bit platforms.
6522
Walter Dörwalded960ac2009-05-03 22:36:33 +00006523- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6524 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6525 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6526 of using the replace error handler in PyUnicode_DecodeUTF8().
6527
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006528- Issue #3739: The unicode-internal encoder now reports the number of characters
6529 consumed like any other encoder (instead of the number of bytes).
6530
Georg Brandlba83f822010-03-14 09:50:54 +00006531- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6532 allocator will be automatically disabled when running under Valgrind. This
6533 gives improved memory leak detection when running under Valgrind, while taking
6534 advantage of pymalloc at other times.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007925- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7926 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7927 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7928 ``printf`` function, whereas PyString_FromFormat has an independent
7929 implementation and uses "%zd" on all platforms for size_t values.
7930 This makes a difference on win64, where ``printf`` needs "%Id" to display
7931 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00007951 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7952 mechanism. In the process, fix a bug where isinstance() and issubclass(),

7954 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7955 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008094What's New in Python 2.6 beta 3?
8095================================
8096
Barry Warsaw07a4a382008-08-21 01:15:08 +00008097*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008098
8099Core and Builtins
8100-----------------
8101
Guido van Rossumf8402962008-08-20 15:01:50 +00008102- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8103 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8104 extensions do not automatically benefit from the class attribute
8105 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8106 to their tp_flags field if they care. This is a backwards
8107 compatibility feature; in 3.0, all types will use the cache by
8108 default.
8109
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008110- Keyword arguments can now follow starred arguments. (``f(a, *args,
8111 keyword=23)`` is now valid syntax.)
8112
Thomas Heller0ad5ae02008-08-19 19:25:04 +00008113- ctypes function pointers that are COM methods have a boolean True
8114 value again.
8115
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00008116- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
8117 by denying s# to parse objects that have a releasebuffer procedure,
8118 and introducing s*.
8119
Georg Brandl1e13ea92008-08-11 09:07:59 +00008120- Issue #3537: Fix an assertion failure when an empty but presized dict
8121 object was stored in the freelist.
8122
Mark Dickinsonb6467572008-08-04 21:30:09 +00008123- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8124 ValueError consistently across platforms.
8125
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008126- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8127 (64bit Unix, for example), unichr() would truncate its argument and return
8128 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8129
Neal Norwitze7d8be82008-07-31 17:17:14 +00008130- Apply security patches from Apple.
8131
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008132- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8133 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8134
Antoine Pitrou92f82162008-07-25 22:22:08 +00008135- Issue #1819: function calls with several named parameters are now on
8136 average 35% faster (as measured by pybench).
8137
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008138- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8139 the python debugger steps into a class statement: the free variables (local
8140 variables defined in an outer scope) would be deleted from the outer scope.
8141
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008142- Issue #2620: Overflow checking when allocating or reallocating memory
8143 was not always being done properly in some python types and extension
8144 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8145 all been updated to perform better checks and places in the code that
8146 would previously leak memory on the error path when such an allocation
8147 failed have been fixed.

8150-------
8151
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00008152- Issue #3612: Added some missing basic types in ctypes.wintypes.
8153
Benjamin Petersone977ad42008-08-20 01:42:01 +00008154- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8155 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8156
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008157- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8158 version reported by these tools does not necessarily follow the python
8159 version numbering scheme, so the module is less strict when parsing it.
8160
Nick Coghlanf70385a2008-08-18 12:42:46 +00008161- Issue #2235: Added Py3k warnings for types which will become unhashable
8162 under the stricter __hash__ inheritance rules in 3.0. Several types
8163 which did not meet the rules for hash invariants and were already
8164 unhashable in 3.0 have now been explicitly flagged as unhashable in
8165 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8166 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8167
Brett Cannon88f801d2008-08-18 00:46:22 +00008168- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8169 imported into the module but exposed as part of the module's API.
8170
Brett Cannon7b96f072008-08-18 00:41:11 +00008171- Remove an unneeded import of abc.ABCMeta from 'inspect'.
8172
Brett Cannon46225e72008-08-18 00:36:52 +00008173- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
8174
Brett Cannon25c9d6a2008-08-17 22:10:11 +00008175- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
8176
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00008177- Issue #3575: Incremental decoder's decode function now takes bytearray
8178 by using 's*' instead of 't#'.
8179
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008180- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008181 fails unicode conversion on 2nd parameter. (windows only)
8182
Georg Brandl222e2082010-08-01 22:27:39 +00008183- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00008184 in a redirect.
8185
Brett Cannonabe423e2008-08-16 21:47:07 +00008186- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00008187 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00008188
Facundo Batistaeb90b782008-08-16 14:44:07 +00008189- Issue #2776: fixed small issue when handling an URL with double slash
8190 after a 302 response in the case of not going through a proxy.
8191
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008192- Issue #2676: in the email package, content-type parsing was hanging on
8193 pathological input because of quadratic or exponential behaviour of a
8194 regular expression.
8195
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008196- Issue #3476: binary buffered reading through the new "io" library is now
8197 thread-safe.
8198
Brett Cannonbf3157b2008-08-14 05:00:03 +00008199- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8200 since mimetools itself is deprecated. Because modules are cached, all
8201 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8202
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008203- Issue #3134: shutil referenced undefined WindowsError symbol.
8204
Robert Schuppenies14646332008-08-10 11:01:53 +00008205- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8206 menu entries were not deleted.
8207
Brett Cannon83e81842008-08-09 23:30:55 +00008208- Copied the implementation of reduce() to _functools.reduce() to have a
8209 version that did not raise a DeprecationWarning under -3.
8210
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008211- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8212 a MemoryError rather than silently stop the iteration.
8213
Guido van Rossum59ce9012008-08-09 14:55:34 +00008214- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8215 to _sre.compile() will now be rejected. This should not affect anybody
8216 since the re.compile() function never generates invalid re-bytecode.
8217
Skip Montanaroa032bf42008-08-08 22:52:51 +00008218- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8219 upon first access it can be automatically initialized from the csv file if
8220 it wasn't initialized during instantiation.
8221
Brett Cannon3aa2a492008-08-06 22:28:09 +00008222- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8223 the reload() built-in has been removed.
8224
Brett Cannon7e30b672008-08-04 21:52:25 +00008225- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008226 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

8231 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00008232
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00008233- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
8234 raised an AttributeError.
8235
Benjamin Peterson01a24322008-07-28 23:35:27 +00008236- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00008237 asking for a specific length. This problem only affected files opened
8238 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00008239
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00008240- Issue #3449: Update decimal module to use most recent specification
8241 (v. 1.68) and tests (v. 2.58) from IBM.
8242
Georg Brandl222e2082010-08-01 22:27:39 +00008243- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00008244

8247
Georg Brandlf9efabb2008-07-23 15:16:45 +00008248- Deprecate the "ast" parser function aliases.
8249
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008250- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
8251
8252- Issue #3303: Fix a crash in locale.strcoll() when calling it with
8253 invalid arguments.
8254
8255- Issue #3302: Fix several crashes when calling locale's gettext functions
8256 with None arguments.
8257
8258- Issue #3389: Allow resolving dotted names for handlers in logging
8259 configuration files.
8260
8261- Deprecate the sunaudio module for removal in Python 3.0.
8262
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00008263- Issue #3394: zipfile.writestr sets external attributes when passed a
8264 file name rather than a ZipInfo instance, so files are extracted with
8265 mode 0600 rather than 000 under Unix.
8266
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00008267- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
8268 argument in python 2.5, this broke code that subclassed Popen to include its
8269 own poll method. Fixed my moving _deadstate to an _internal_poll method.

8280 interaction with the tp_hash slot (added in 2.6b2) are now documented
8281
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008282- Issue #643841: The language reference now provides more detailed
8283 coverage of the lookup process for special methods. The disclaimers
8284 regarding lack of coverage of new-style classes have also been
8285 removed, since the coverage is now fairly reasonable.

8289================================
8290
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008291*Release date: 17-Jul-2008*
8292
Raymond Hettingere3ae6552008-06-20 04:18:15 +00008293Core and Builtins
8294-----------------
8295
Georg Brandl3e483f62008-07-16 22:57:41 +00008296- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8297 its methods now allow for items objects that can be converted to
8298 an integer using operator.index().
8299
Mark Dickinson64b7e502008-07-16 09:40:03 +00008300- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8301 produced a ValueError instead of giving the correct float.
8302
Eric Smitha5fa5a22008-07-16 00:11:49 +00008303- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8304 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8305
Mark Dickinson7103aa42008-07-15 19:08:33 +00008306- Issue #3008: the float type has a new instance method 'float.hex'
8307 and a new class method 'float.fromhex' to convert floating-point
8308 numbers to and from hexadecimal strings, respectively.
8309
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008310- Issue #2235: __hash__ is once again inherited by default. To allow
8311 collections.Hashable to remain meaningful in the presence of the
8312 default hash implementation (object.__hash__), it is now possible
8313 to explicit block inheritance of hash by setting __hash__=None at
8314 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8315 level.
8316
Nick Coghlanb028f502008-07-13 14:52:36 +00008317- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8318 the parent module cannot be found while performing an absolute import.
8319 This means that an incorrectly defined __package__ attribute will
8320 now only prevent relative imports in that module rather than causing
8321 all imports from that module to fail.
8322
Nick Coghlan14ff9942008-07-08 14:21:42 +00008323- Issue #2517: Allow unicode messages in Exceptions again by correctly
8324 bypassing the instance dictionary when looking up __unicode__ on
8325 new-style classes.
8326
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008327- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8328 set to a custom object whose write() method happens to install
8329 another file in sys.stdout.
8330
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008331- Issue #3088: Corrected a race condition in classes derived from
8332 threading.local: the first member set by a thread could be saved in
8333 another thread's dictionary.
8334
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008335- Issue #3004: Minor change to slice.indices(): the start and stop
8336 arguments are now treated identically, making the behaviour easier
8337 to describe and understand. For example, slice(None, -10,
8338 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8339 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8340 10, -1).
8341
Georg Brandl278fc502008-07-19 12:46:12 +00008342- Issue #3219: Calling a function with repeated keyword arguments,
8343 f(a=2, a=23), would not cause a syntax error. This was a regression
8344 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008345
Georg Brandl278fc502008-07-19 12:46:12 +00008346- Issue #2862: Make int and float freelist management consistent with
8347 other freelists. Changes their CompactFreeList apis into
8348 ClearFreeList apis and calls them via gc.collect().

Georg Brandl5cc774e2008-06-11 20:28:06 +00008792 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008793
8794 This is controlled by the configure argument ``--with-universal-archs``:
8795
8796 - ``--with-universal-archs=all``: install 4-way universal
8797
8798 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8799
8800 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8801
8802 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008853- Issue #1631171: Re-implement the 'warnings' module in C (the
8854 original Python code has been kept as backup). This will allow for
8855 using the 'warning's machinery in such places as the parser where
8856 use of pure Python code is not possible. Both the ``showarning()``
8857 and ``formatwarning()`` gain an optional 'line' argument which is
8858 not called by default for backwards-compatibility reasons. Setting
8859 ``warnings.showwarning()`` to an implementation that lacks support
8860 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008923- Issue #2550: The approach used by client/server code for obtaining
8924 ports to listen on in network-oriented tests has been refined in an
8925 effort to facilitate running multiple instances of the entire
8926 regression test suite in parallel without issue.
8927 test_support.bind_port() has been fixed such that it will always
8928 return a unique port -- which wasn't always the case with the
8929 previous implementation, especially if socket options had been set
8930 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8931 new implementation of bind_port() will actually raise an exception
8932 if it is passed an AF_INET/SOCK_STREAM socket with either the
8933 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8934 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8935 the socket it's been passed. This currently only applies to
8936 Windows. This option prevents any other sockets from binding to the
8937 host/port we've bound to, thus removing the possibility of the
8938 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8939 when a second SOCK_STREAM socket binds and accepts to a host/port
8940 that's already been bound by another socket. The optional preferred
8941 port parameter to bind_port() has been removed. Under no
8942 circumstances should tests be hard coding ports!
8943
8944 test_support.find_unused_port() has also been introduced, which will
8945 pass a temporary socket object to bind_port() in order to obtain an
8946 unused port. The temporary socket object is then closed and
8947 deleted, and the port is returned. This method should only be used
8948 for obtaining an unused port in order to pass to an external program
8949 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8950 a parameter to a server-oriented class that doesn't give you direct
8951 access to the underlying socket used.
8952
8953 Finally, test_support.HOST has been introduced, which should be used
8954 for the host argument of any relevant socket calls (i.e. bind and
8955 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008956
8957 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008958 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008959 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8960 test_asynchat and test_socket_ssl.
8961
Georg Brandl3ee81df2008-05-17 18:14:43 +00008962 It is now possible for multiple instances of the regression test
8963 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00009167- The bundled libffi copy is now in sync with the recently released
9168 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009169 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
9170 files are used. On all linux systems the --with-system-ffi
9171 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00009232- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00009233 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00009235- Issue #2067: file.__exit__() now calls subclasses' close() method.
9236
9237- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00009238
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009239- Issue #1881: An internal parser limit has been increased. Also see

Facundo Batistafc2d0102008-02-23 12:01:13 +00009241
Eric Smitha73fbe72008-02-23 03:09:44 +00009242- Added the future_builtins module, which contains hex() and oct().
9243 These are the PEP 3127 version of these functions, designed to be
9244 compatible with the hex() and oct() builtins from Python 3.0. They
9245 differ slightly in their output formats from the existing, unchanged
9246 Python 2.6 builtins. The expected usage of the future_builtins
9247 module is:
9248 from future_builtins import hex, oct
9249
Eric Smith7ef40bf2008-02-20 23:34:22 +00009250- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9251 exponents for exponents with absolute value < 100. Follows C99
9252 standard. This is a change on Windows, which would use 3 digits.
9253 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9254 so that any alterations it does to the resulting string will be
9255 available in stringlib/formatter.h (for float.__format__).
9256
Eric Smith5a3c1352008-02-19 13:21:56 +00009257- Implemented PEP 3101, Advanced String Formatting. This adds a new
9258 builtin format(); a format() method for str and unicode; a
9259 __format__() method to object, str, unicode, int, long, float, and
9260 datetime; the class string.Formatter; and the C API
9261 PyObject_Format().
9262
Georg Brandl3ee81df2008-05-17 18:14:43 +00009263- Fixed several potential crashes, all caused by specially crafted
9264 __del__ methods exploiting objects in temporarily inconsistent
9265 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009266
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009267- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009268 prevent a possible crash: an Abstract Base Class would try to access
9269 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009270

Georg Brandl3ee81df2008-05-17 18:14:43 +00009274- Clear all free lists during a gc.collect() of the highest generation
9275 in order to allow pymalloc to free more arenas. Python may give back
9276 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009277
Georg Brandl3ee81df2008-05-17 18:14:43 +00009278- Issue #2045: Fix an infinite recursion triggered when printing a
9279 subclass of collections.defaultdict, if its default_factory is set
9280 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009281
Christian Heimesf75dbef2008-02-08 00:11:31 +00009282- Fixed a minor memory leak in dictobject.c. The content of the free
9283 list was not freed on interpreter shutdown.
9284
Georg Brandl21e99f42010-03-07 15:23:59 +00009285- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009286 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009287
Georg Brandl3ee81df2008-05-17 18:14:43 +00009288- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9289 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009290 to compact the internal free lists of pre-allocted ints and floats.
9291
Georg Brandl3ee81df2008-05-17 18:14:43 +00009292- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9293 calls. Python expected the return type int but the fork familie
9294 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009295
Georg Brandl3ee81df2008-05-17 18:14:43 +00009296- Issue #1678380: Fix a bug that identifies 0j and -0j when they
9297 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00009298

Georg Brandl3ee81df2008-05-17 18:14:43 +00009308- Patch #1473257: generator objects gain a gi_code attribute. This is
9309 the same object as the func_code attribute of the function that
9310 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009311
Georg Brandl3ee81df2008-05-17 18:14:43 +00009312- Issue #1920: "while 0" statements were completely removed by the
9313 compiler, even in the presence of an "else" clause, which is
9314 supposed to be run when the condition is false. Now the compiler
9315 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009316
Guido van Rossumeead05f2008-01-24 18:21:02 +00009317- A few crashers fixed: weakref_in_del.py (issue #1377858);
9318 loosing_dict_ref.py (issue #1303614, test67.py);
9319 borrowed_ref_[34].py (not in tracker).
9320
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009321- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009322 suppressed while an extension is loaded by calling SetErrorMode in
9323 dynload_win.c. The error is still reported properly.
9324
Georg Brandl3ee81df2008-05-17 18:14:43 +00009325- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009326 several extension methods and modules do not work without unicode
9327 support.
9328
Georg Brandl26543b12008-01-21 18:36:51 +00009329- Issue #1882: when compiling code from a string, encoding cookies in the
9330 second line of code were not always recognized correctly.
9331
Georg Brandl14404b62008-01-19 19:27:05 +00009332- Issue #1679: "0x" was taken as a valid integer literal.
9333
Georg Brandl6caad7d2008-01-26 14:19:22 +00009334- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009335 added.
9336
Christian Heimesc94e2b52008-01-14 04:13:37 +00009337- sys.float_info / PyFloat_GetInfo: The floating point information
9338 object was converted from a dict to a specialized structseq object.
9339
Georg Brandl3ee81df2008-05-17 18:14:43 +00009340- Patch #1816: Added sys.flags structseq. It exposes the status of
9341 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009342
Georg Brandl3ee81df2008-05-17 18:14:43 +00009343- Objects/structseq.c: Implemented new structseq representation. The
9344 patch makes structseqs (e.g. the return value of os.stat) more
9345 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009346
Georg Brandl3ee81df2008-05-17 18:14:43 +00009347- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00009359- Improve some exception messages when Windows fails to load an
9360 extension module. Now we get for example '%1 is not a valid Win32
9361 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009369 and INF. float("nan"), float("inf") and float("-inf") now work on
9370 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009371
Georg Brandl3ee81df2008-05-17 18:14:43 +00009372- Compiler now generates simpler and faster code for dictionary
9373 literals. The oparg for BUILD_MAP now indicates an estimated
9374 dictionary size. There is a new opcode, STORE_MAP, for adding
9375 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009404- Patch #1739468: Directories and zipfiles containing a __main__.py
9405 file can now be directly executed by passing their name to the
9406 interpreter. The directory/zipfile is automatically inserted as the
9407 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009409- Issue #1265: Fix a problem with sys.settrace, if the tracing
9410 function uses a generator expression when at the same time the
9411 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009412
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009413- sets and frozensets now have an isdisjoint() method.
9414

9416
Neal Norwitz44f326e2007-10-05 05:29:17 +00009417- Fix warnings found by the new version of the Coverity checker.
9418
Georg Brandl21e99f42010-03-07 15:23:59 +00009419- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009420 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9421 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009422
Georg Brandl3ee81df2008-05-17 18:14:43 +00009423- Issue #1686386: Tuple's tp_repr did not take into account the
9424 possibility of having a self-referential tuple, which is possible
9425 from C code. Nor did object's tp_str consider that a type's tp_str
9426 could do something that could lead to an inifinite recursion.
9427 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9428 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009429
Georg Brandl3ee81df2008-05-17 18:14:43 +00009430- Issue #1164: It was possible to trigger deadlock when using the
9431 'print' statement to write to a file since the GIL was not released
9432 as needed. Now PyObject_Print() does the right thing along with
9433 various tp_print implementations of the built-in types and those in
9434 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009435
Georg Brandl3ee81df2008-05-17 18:14:43 +00009436- Issue #1147: Exceptions were directly allowing string exceptions in
9437 their throw() method even though string exceptions no longer
9438 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009439
Georg Brandl3ee81df2008-05-17 18:14:43 +00009440- Issue #1096: Prevent a segfault from getting the repr of a very
9441 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009442
Brett Cannon1e534b52007-09-07 04:18:30 +00009443- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009444 PyObject_Call() never calling back out to Python code to trigger
9445 recursion depth updates/checks. Required the creation of a static
9446 RuntimeError instance in case normalizing an exception put the
9447 recursion check value past its limit. Fixes crashers
9448 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009449
Georg Brandl3ee81df2008-05-17 18:14:43 +00009450- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00009463- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009464 __*__ attributes. (Some already existed, e.g., __doc__ and
9465 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009466
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009467- Add -3 option to the interpreter to warn about features that are
9468 deprecated and will be changed/removed in Python 3.0.
9469
Georg Brandl2134e752007-05-21 20:34:16 +00009470- Patch #1686487: you can now pass any mapping after '**' in function
9471 calls.
9472
Collin Winter62903052007-05-18 23:11:24 +00009473- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009474 "except E as target:". This is to provide forwards compatibility
9475 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009476
Brett Cannon229cee22007-05-05 01:34:02 +00009477- Deprecate BaseException.message as per PEP 352.
9478
Georg Brandl3ee81df2008-05-17 18:14:43 +00009479- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009480 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009481
Vinay Sajip8549ce32007-05-06 17:53:37 +00009482- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009483 setting a plain string, ie don't expand to single letter identifiers.
9484
Raymond Hettinger13936692007-04-11 18:40:58 +00009485- Request #1191699: Slices can now be pickled.
9486
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009487- Request #1193128: str.translate() now allows a None argument for
9488 translations that only remove characters without re-mapping the
9489 remaining characters.
9490
Georg Brandl5cb76c12007-03-21 09:00:39 +00009491- Patch #1682205: a TypeError while unpacking an iterable is no longer
9492 masked by a generic one with the message "unpack non-sequence".
9493
Neal Norwitzaa754b72007-03-21 06:39:48 +00009494- Remove unused file Python/fmod.c.
9495
Guido van Rossum143b5642007-03-23 04:58:42 +00009496- Bug #1683368: The object.__init__() and object.__new__() methods are
9497 now stricter in rejecting excess arguments. The only time when
9498 either allows excess arguments is when it is not overridden and the
9499 other one is. For backwards compatibility, when both are
9500 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009501 warning later). Also, type.__init__() insists on the same signature
9502 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009503
Georg Brandl3ee81df2008-05-17 18:14:43 +00009504- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9505 object to complex using its __complex__() method before falling back
9506 to the __float__() method. Therefore, the functions in the cmath
9507 module now can operate on objects that define a __complex__()
9508 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009509
Georg Brandl3ee81df2008-05-17 18:14:43 +00009510- Patch #1623563: allow __class__ assignment for classes with
9511 __slots__. The old and the new class are still required to have the
9512 same slot names.

9518 ``object.__reduce_ex__()`` is called with an object that is faking
9519 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009520
Georg Brandl3ee81df2008-05-17 18:14:43 +00009521- Patch #1680015: Don't modify __slots__ tuple if it contains an

9525
Georg Brandl7b9c5552007-03-12 14:30:05 +00009526- Bug #1678647: write a newline after printing an exception in any
9527 case, even when converting the value to a string failed.
9528
Georg Brandl871f1bc2007-03-12 13:17:36 +00009529- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009530 its argument, if it exists. If not, it will work like before. This
9531 allows customizing the output of dir() in the presence of a
9532 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009540- Patch #1491866: change the complex() constructor to allow
9541 parthensized forms. This means complex(repr(x)) now works instead of
9542 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009543
Georg Brandlaa2321b2007-03-07 00:40:28 +00009544- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009545 makes the filenames the warning module prints much more sensible
9546 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009547

9549 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00009550 variable is given, but break into the interactive interpreter just
9551 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00009559- Patch #1674228: when assigning a slice (old-style), check for the
9560 sq_ass_slice instead of the sq_slice slot.
9561
Georg Brandl3ee81df2008-05-17 18:14:43 +00009562- When printing an unraisable error, don't print exceptions. before
9563 the name. This duplicates the behavior whening normally printing
9564 exceptions.

Thomas Hellerd2ea4a22006-10-17 19:30:48 +000010403- ctypes callback functions only support 'fundamental' data types as

10460 the first chunk fed to the decoder started with a BOM, but was
10461 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010462
Georg Brandl3ee81df2008-05-17 18:14:43 +000010463- The implementation of UnicodeError objects has been simplified
10464 (start and end attributes are now stored directly as Py_ssize_t
10465 members).

10470 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +000010471
Georg Brandl3ee81df2008-05-17 18:14:43 +000010472- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010473 that the SMTP.starttls() caller no longer needs to call ehlo()
10474 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010475 does not claim to support starttls. Adds the
10476 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
10477 Fenner.

Georg Brandl309501a2008-01-19 20:22:13 +000010518
Georg Brandl3ee81df2008-05-17 18:14:43 +000010519- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010520 works as expected. ``mmap.find`` also takes an optional ``end``
10521 parameter.
10522
Georg Brandl3ee81df2008-05-17 18:14:43 +000010523- _winreg's HKEY object has gained __enter__ and __exit__ methods to

10546 contents before adding elements from the iterable. This fix brings
10547 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +000010548

10557 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10558 silently miscode subclasses of those types. Now, it raises a
10559 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010560

Georg Brandl3ee81df2008-05-17 18:14:43 +000010575 time so that opening a database previously created with the DB_DUP
10576 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10577 opens. Specifically: dictionary assignment to a DB object will
10578 replace all values for a given key when the database allows
10579 duplicate values. DB users should use DB.put(k, v) when they want
10580 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010581
Gregory P. Smithac11e022007-11-05 02:56:31 +000010582- Add the bsddb.db.DBEnv.lock_id_free method.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010586- Patch #1185447: binascii.b2a_qp() now correctly quotes binary
10587 characters with ASCII value less than 32. Also, it correctly quotes
10588 dots only if they occur on a single line, as opposed to the previous
10589 behavior of quoting dots if they are the second character of any
10590 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010591
Georg Brandla47337f2007-03-13 12:34:25 +000010592- Bug #1622896: fix a rare corner case where the bz2 module raised an

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +000010865- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +000010866 periodic threadstate and signal checking in tight loops. By
10867 default, this option is turned-off. It should only be enabled in
10868 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +000010869

10919
Georg Brandl3ee81df2008-05-17 18:14:43 +000010920- Unified naming convention for free lists and their limits. All free
10921 lists in Object/ are named ``free_list``, the counter ``numfree``
10922 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10923 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010924
Georg Brandl3ee81df2008-05-17 18:14:43 +000010925- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10926 to ``PyTuple_SetItem``, it can be used to populate a brand new
10927 frozenset; but it does not steal a reference to the added item.

10939
Georg Brandl3ee81df2008-05-17 18:14:43 +000010940- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10941 of w# format code incorrectly truncated the length to an int, even
10942 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10943 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010944
Georg Brandl3ee81df2008-05-17 18:14:43 +000010945- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

10962
10963- Fix some leftovers from the conversion from int to Py_ssize_t
10964 (relevant to strings and sequences of more than 2**31 items).
10965
10966- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10967 outside of pystate.c and should not be necessary.
10968
Georg Brandl3ee81df2008-05-17 18:14:43 +000010969- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10970 absolute imports. In earlier versions they might have used relative
10971 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010972
Georg Brandl3ee81df2008-05-17 18:14:43 +000010973- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10974 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010975
Georg Brandl3ee81df2008-05-17 18:14:43 +000010976- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010999- Removed the macfs module. It had been deprecated since Python 2.5.
11000 This lead to the deprecation of macostools.touched() as it relied
11001 solely on macfs and was a no-op under OS X.
