Ned Deily657b2de2011-06-28 19:51:30 -0700788- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
789 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
790 interpreter process. This could cause failures in non-Distutils subprocesses
791 and was unreliable since tests or user programs could modify the interpreter
792 environment after Distutils set it. Instead, have Distutils set the the
793 deployment target only in the environment of each build subprocess. It is
794 still possible to globally override the default by setting
795 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
796 greater or equal to the default value, the value with which the interpreter

Georg Brandl255abdd2011-01-16 14:17:26 +00002047 continuation line in the formatted value has no leading white space and looks
2048 like a header. Since Generator uses Header to format all headers, this check
2049 is made for all headers in any serialized message at serialization time. This
2050 provides protection against header injection attacks.

Georg Brandl255abdd2011-01-16 14:17:26 +00002060 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00002061
Éric Araujof0ab5d62011-05-29 03:43:59 +02002062- email.header.Header was incorrectly encoding folding whitespace when

2070 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
2071 supported by the OS. With Visual Studio or on Solaris, the year is limited to
2072 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

3055
Victor Stinner257d38f2010-10-09 10:12:11 +00003056- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()

Georg Brandl27a28582010-10-10 09:49:21 +00003059- ast.literal_eval() can now handle negative numbers. It is also a little more
3060 liberal in what it accepts without compromising the safety of the evaluation.
3061 For example, 3j+4 and 3+4+5 are both accepted.

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00003088- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other

3090 Py_Initialize().
3091
Georg Brandl27a28582010-10-10 09:49:21 +00003092- All SyntaxErrors now have a column offset and therefore a caret when the error
3093 is printed.

Brett Cannonbc2eff32010-09-19 21:39:02 +00003095- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3096 module that was imported, but instead gets the module from sys.modules.
3097
Nick Coghlan37ee8502010-12-03 14:26:13 +00003098- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00003101- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3102 with a non-empty format string. This is an effort to future-proof user
3103 code. If a derived class does not currently implement __format__ but later
3104 adds its own __format__, it would most likely break user code that had
3105 supplied a format string. This will be changed to a DeprecationWaring in
3106 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00003108- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3109 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3110 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3111
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003112- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3113 functions from the libc caused the methods .upper() and lower() to become
3114 locale aware and created subtly wrong results.
3115
Georg Brandl27a28582010-10-10 09:49:21 +00003116- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3117 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003118
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003119- Issue #4617: Previously it was illegal to delete a name from the local
3120 namespace if it occurs as a free variable in a nested block. This limitation
3121 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3122
Georg Brandl27a28582010-10-10 09:49:21 +00003123- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3124 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3125 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3126 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00003127
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003128- Issue #9757: memoryview objects get a release() method to release the
3129 underlying buffer (previously this was only done when deallocating the
3130 memoryview), and gain support for the context management protocol.
3131
Antoine Pitrou079ce542010-09-08 12:37:10 +00003132- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3133 thread-local storage key.

Éric Araujoef777bd2010-10-05 00:04:20 +00003161- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003162 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003163 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003164 replacement for old handle_accept() and avoids the user to call accept()

Antoine Pitrou98b46702010-09-18 22:59:00 +00003237- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00003238 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003271- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003272 it possible for the user to create self-referencing ordered dictionaries which
3273 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003274 approach of using weakref proxies so that reference cycles never get created
3275 in the first place.

3283 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3284 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003285

Georg Brandl27a28582010-10-10 09:49:21 +00003296- Issue #9707: Rewritten reference implementation of threading.local which is
3297 friendlier towards reference cycles. This change is not normally visible

Antoine Pitrou783eea72010-09-07 22:06:17 +00003299
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003300- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3301 still return the id of the parent process after it has exited. This process
3302 id may even have been reused by another unrelated process.
3303
Georg Brandl27a28582010-10-10 09:49:21 +00003304- Issue #9792: In case of connection failure, socket.create_connection() would
3305 swallow the exception and raise a new one, making it impossible to fetch the
3306 original errno, or to filter timeout errors. Now the original error is
3307 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00003308
Georg Brandl27a28582010-10-10 09:49:21 +00003309- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3310 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3311 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003313- Updates to the random module:
3314
Georg Brandl27a28582010-10-10 09:49:21 +00003315 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00003318 * Update the seed() method to use all of the bits in a string instead of just
3319 the hash value. This makes better use of the seed value and assures the
3320 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003322 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3323 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3324 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003325
3326 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003345- hashlib has two new constant attributes: algorithms_guaranteed and
3346 algorithms_avaiable that respectively list the names of hash algorithms
3347 guaranteed to exist in all Python implementations and the names of hash
3348 algorithms available in the current process.
3349

Georg Brandl62069d32010-07-31 08:56:11 +00003861 start byte and the continuation byte(s) are now considered invalid, instead of
3862 the number of bytes specified by the start byte. E.g.:
3863 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3864 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3865 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3866 returned a single u'\ufffd'.

4273 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4274 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004275 to match the behaviour of the other integer format codes.

4304 gives improved memory leak detection when running under Valgrind, while taking
4305 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00004378- The default size of the re module's compiled regular expression cache has been
4379 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00004380 simply clearing the entire cache on overflow to forgetting the least recently
4381 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004382 applications that use a lot of regular expressions and limits the impact of
4383 the performance hit anytime the cache is exceeded.

4399 minor modifications by the PyPy project. The test suite now tests `datetime`
4400 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004637- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4638 operation raises multiple signals and more than one of those signals is
4639 trapped, the specification determines the order in which the signals should be
4640 handled. In many cases this order wasn't being followed, leading to the wrong

4681 socket wasn't retained (instead, a socket with a positive timeout would be
4682 turned into a non-blocking SSL socket).

Georg Brandl62069d32010-07-31 08:56:11 +00004797- Issue #2531: Comparison operations between floats and Decimal instances now
4798 return a result based on the numeric values of the operands; previously they
4799 returned an arbitrary result based on the relative ordering of id(float) and

Georg Brandl62069d32010-07-31 08:56:11 +00005144 default when instantiating a `threading.RLock` object. This makes recursive
5145 locks as fast as regular non-recursive locks (previously, they were slower by
5146 10x to 15x).

Georg Brandl62069d32010-07-31 08:56:11 +00005299 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
5300 PyPycLoader inherit from this class and provide implementations in relation to
5301 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00005302
Brett Cannon64ef00f2009-07-20 03:19:18 +00005303- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
5304 the documentation said it did even though the code in PyLoader relied on the
5305 abstract method required by ResourceLoader.
5306
Georg Brandl62069d32010-07-31 08:56:11 +00005307- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsoncf28b952010-07-29 21:41:59 +00005358- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
5359
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005360- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005361 compared to other unix systems. In particular, os.getgroups() does not reflect
5362 any changes made using os.setgroups() but basicly always returns the same
5363 information as the id command. os.getgroups() can now return more than 16
5364 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005365

5385
Benjamin Petersonf751bc92010-07-02 13:46:42 +00005386- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
5387 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00005388
Georg Brandl62069d32010-07-31 08:56:11 +00005389- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5390 Prior to this change, timezone adjustment in utctimetuple() could produce
5391 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5392 cases.
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00005393
Georg Brandl62069d32010-07-31 08:56:11 +00005394- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5395 directive. When the ``%z`` directive is present in the format string, an
5396 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5397 ``datetime.timezone`` instance constructed from the parsed offset. If both
5398 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5399 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00005400
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005401- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005402 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5403 ``datetime.timezone``, return fixed name and UTC offset from their
5404 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5405 returns ``None``. A class attribute, ``utc`` contains an instance
5406 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00005422- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
5423 with an improved 'binary-split' algorithm that uses fewer multiplications and
5424 allows many of the multiplications to be performed using plain C integer
5425 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

5430
Mark Dickinson0381e3f2010-05-08 14:35:02 +00005431- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5432 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005433 the result is now always correctly rounded, and is equivalent to ``td /
5434 timedelta(seconds=1)``.

5443 integer format code, struct.pack first attempts to convert the non-integer
5444 using its __index__ method. If that method is non-existent or raises
5445 TypeError it goes on to try the __int__ method, as described below.
5446

6026 default precision of 12. Previously, the behavior the same but with
6027 a default precision of 6. This more closely matches str(), and
6028 reduces surprises when adding alignment flags to the empty
6029 presentation type. This also affects the new complex.__format__ in
6030 the same way.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00006073- Issue #1869 (and many duplicates): make round(x, n) correctly
6074 rounded for a float x, by using the decimal <-> binary conversions
6075 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6076 consistently agrees with format(x, '.2f').
6077
Benjamin Petersonae937c02009-04-18 20:54:08 +00006078- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

6082
Eric Smith35e84722009-04-16 20:21:28 +00006083- Issue #5515: str.format() type 'n' combined with commas and leading
6084 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006085
6086- Implement PEP 378, Format Specifier for Thousands Separator, for
6087 floats.
6088
Mark Dickinson3370cce2009-04-17 22:40:53 +00006089- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006090 1e11, not 1e12. This avoids printing 13 significant digits in
6091 situations where only 12 of them are correct. Example problem
6092 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6093 long time.)
6094
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006095- Issue #1580: On most platforms, use a 'short' float repr: for a
6096 finite float x, repr(x) now outputs a string based on the shortest
6097 sequence of decimal digits that rounds to x. Previous behaviour was
6098 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006099 Another minor difference is that the new repr switches to
6100 exponential notation at 1e16 instead of the previous 1e17; this
6101 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006102
6103 There's a new sys attribute sys.float_repr_style, which takes
6104 the value 'short' to indicate that we're using short float repr,
6105 and 'legacy' if the short float repr isn't available for one
6106 reason or another.
6107
6108 The float repr change involves incorporating David Gay's 'perfect
6109 rounding' code into the Python core (it's in Python/dtoa.c). As a
6110 secondary consequence, all string-to-float and float-to-string
6111 conversions (including all float formatting operations) will be
6112 correctly rounded on these platforms.
6113
Georg Brandl5f90d792010-08-01 22:31:05 +00006114 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006115 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006117- Issue #5759: float() didn't call __float__ on str subclasses.
6118
Georg Brandlabc38772009-04-12 15:51:51 +00006119- The string.maketrans() function is deprecated; there is a new static method
6120 maketrans() on the bytes and bytearray classes. This removes confusion about
6121 the types string.maketrans() is supposed to work with, and mirrors the
6122 methods available on the str class.
6123
R. David Murraydc6da8a2009-04-09 22:16:43 +00006124- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

6291 untrackable objects are not tracked by the garbage collector. This can
6292 reduce the size of collections and therefore the garbage collection overhead
6293 on long-running programs, depending on their particular use of datatypes.

6301 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6302 --enable-big-digits option to configure, which overrides the
6303 default. Add sys.int_info structseq to provide information about
6304 the internal format.

6358 (typically /dev/zero under Unix) could crash the interpreter.
6359
Benjamin Peterson59406a92009-03-26 17:10:29 +00006360- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

6362
Lars Gustäbel42e00912009-03-22 20:34:29 +00006363- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6364 forever on incomplete input. That caused tarfile.open() to hang when used
6365 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6366 partial bzip2 compressed data.
6367
Mark Dickinson79f52032009-03-17 23:12:51 +00006368- Issue #2110: Add support for thousands separator and 'n' type

6372 '>' alignment characters.
6373
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00006374- The error detection code in FileIO.close() could fail to reflect the `errno`

6386 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00006387 struct.error instead of returning b'\xff\xff\xff\xff'. The
6388 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
6389 have been removed from the struct module.

6403
Eric Smith5e5c0db2009-02-20 14:25:03 +00006404- Issue #5247: Improve error message when unknown format codes are
6405 used when using str.format() with str, int, and float arguments.
6406
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006407- Issue #5249: time.strftime returned malformed string when format string
6408 contained non ascii character on windows.
6409
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006410- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6411 source has already been decoded into str.
6412
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006413- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6414 rotating the object pointer by 4 bits to the right.
6415
Mark Dickinson87ec0852009-02-09 17:15:59 +00006416- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6417 it now forces its argument to double before testing for infinity.
6418
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006419- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6420 returns a non-number type.
6421
Benjamin Peterson87618552009-02-08 15:00:52 +00006422- Issue #5182: Removed memoryview.__str__.
6423
Mark Dickinsonc008a172009-02-01 13:59:22 +00006424- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6425 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006426 the type definition cmpfunc. The tp_compare slot has been renamed
6427 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006428
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006429- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006430 were suppressing all exceptions. These include list() and bytearray().
6431
Mark Dickinson1124e712009-01-28 21:25:58 +00006432- Issue #4707: round(x, n) now returns an integer if x is an integer.
6433 Previously it returned a float.
6434
Antoine Pitroub52ec782009-01-25 16:34:23 +00006435- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6436 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6437 evaluation loop is compiled with a new dispatch mechanism which gives
6438 speedups of up to 20%, depending on the system, on various benchmarks.
6439
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006440- Issue #4874: Most builtin decoders now reject unicode input.
6441
Mark Dickinson9ffc0202009-01-20 20:45:53 +00006442- Issue #4842: Don't allow trailing 'L' when constructing an integer
6443 from a string.
6444
Benjamin Peterson05e782f2009-01-19 15:15:02 +00006445- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
6446
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00006447- Issue #4838: When a module is deallocated, free the memory backing the
6448 optional module state data.
6449
Mark Dickinson8055afd2009-01-17 10:04:45 +00006450- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006451 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006452
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006453- Issue #4935: The overflow checking code in the expandtabs() method common
6454 to str, bytes and bytearray could be optimized away by the compiler, letting
6455 the interpreter segfault instead of raising an error.
6456
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006457- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6458 __next__ method.
6459
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006460- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6461 function no longer attempt to call the __long__ slot to convert an object
6462 to an integer. Only the __int__ and __trunc__ slots are examined.
6463
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006464- Issue #4893: Use NT threading on CE.
6465
Martin v. Löwisec59d042009-01-12 07:59:10 +00006466- Issue #4915: Port sysmodule to Windows CE.
6467
Antoine Pitrouab868312009-01-10 15:40:25 +00006468- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6469 common cases are optimized thanks to a dedicated fast path and a moderate
6470 amount of loop unrolling.
6471
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006472- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6473 collecting the oldest generation) so that allocating lots of objects without
6474 destroying them does not show quadratic performance. Based on a proposal by
6475 Martin von Löwis at
6476 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6477
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006478- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006479 having been closed (for instance, a read() call could return some
6480 previously buffered data). Patch by Dmitry Vasiliev.
6481
Antoine Pitrou05608432009-01-09 18:53:14 +00006482- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6483 flag to work properly. Furthermore, when specifying -u, the text stdout
6484 and stderr streams have line-by-line buffering enabled (the default being
6485 to buffer arbitrary chunks of data).
6486
Raymond Hettinger35631532009-01-09 03:58:09 +00006487- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6488 instead of ints (reducing its size from 4 to 8 times thereby reducing
6489 Python's overall memory).
6490
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006491- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6492 an existing .py counterpart, override the co_filename attributes of all
6493 code objects if the original filename is obsolete (which can happen if the
6494 file has been renamed, moved, or if it is accessed through different paths).
6495 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6496
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006497- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6498 one byte. Also fixes the meaning of len() so that it returns the number of
6499 items, rather than the size in bytes.
6500
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006501- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6502
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006503- Issue #4747: When the terminal does not use utf-8, executing a script with
6504 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6505
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006506- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6507 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006508
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006509- Issue #3680: Reference cycles created through a dict, set or deque iterator
6510 did not get collected.
6511
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006512- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6513 where the tp_hash and tp_dict slots are both NULL.
6514
Georg Brandlccc47b62008-12-28 11:44:14 +00006515- Issue #4759: None is now allowed as the first argument of
6516 bytearray.translate(). It was always allowed for bytes.translate().
6517
Skip Montanaro80072cb2008-12-23 03:51:14 +00006518- Added test case to ensure attempts to read from a file opened for writing
6519 fail.
6520
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006521- Issue #3106: Speedup some comparisons (str/str and int/int).

6525
Antoine Pitrou621601a2008-12-17 23:18:19 +00006526- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6527 print elapsed times, not only when some objects are uncollectable /
6528 unreachable. Original patch by Neil Schemenauer.
6529
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006530- Issue #3439: Add a bit_length method to int.
6531
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006532- Issue #2173: When getting device encoding, check that return value of
6533 nl_langinfo is not the empty string. This was causing silent build
6534 failures on OS X.
6535
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006536- Issue #4597: Fixed several opcodes that weren't always propagating
6537 exceptions.
6538
6539- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006540 context manager returns a value that cannot be converted to a bool.
6541
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006542- Issue #4445: Replace "sizeof(PyBytesObject)" with
6543 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6544 bytes instances. On a typical machine this saves 3 bytes of memory
6545 (on average) per allocation of a bytes instance.
6546
Christian Heimesa872de52008-12-05 08:26:55 +00006547- Issue #4533: File read operation was dreadfully slow due to a slowly
6548 growing read buffer. Fixed by using the same growth rate algorithm as
6549 Python 2.x.
6550
Antoine Pitrou5504e892008-12-06 21:27:53 +00006551- Issue #4509: Various issues surrounding resize of bytearray objects to
6552 which there are buffer exports (e.g. memoryview instances).
6553
Georg Brandlf9734072008-12-07 15:30:06 +00006554- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6555 method on file objects with closefd=False. The file descriptor is still
6556 kept open but the file object behaves like a closed file. The ``FileIO``
6557 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006558
Antoine Pitroubc420402008-12-07 20:14:49 +00006559- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6560 larger than 1.

6565
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006566- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6567 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6568 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6569 of using the replace error handler in PyUnicode_DecodeUTF8().
