Ned Deily657b2de2011-06-28 19:51:30 -0700596- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
597 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
598 interpreter process. This could cause failures in non-Distutils subprocesses
599 and was unreliable since tests or user programs could modify the interpreter
600 environment after Distutils set it. Instead, have Distutils set the the
601 deployment target only in the environment of each build subprocess. It is
602 still possible to globally override the default by setting
603 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
604 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700605 was built. Also, implement the same handling in packaging.

Steven Bethardb0270112011-01-24 21:02:50 +00001727
1728- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00001729 encodes headers with iso-8859-1 (latin1) encoding. It was already doing

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001827- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001828 continuation line in the formatted value has no leading white space and looks
1829 like a header. Since Generator uses Header to format all headers, this check
1830 is made for all headers in any serialized message at serialization time. This
1831 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001832

Georg Brandl255abdd2011-01-16 14:17:26 +00001841 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001842
Éric Araujof0ab5d62011-05-29 03:43:59 +02001843- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001844 rfc2047-encoding header values with embedded newlines, leaving them without
1845 folding whitespace. It now uses the continuation_ws, as it does for

Victor Stinner3ec899f2011-01-08 16:37:47 +00001848- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1849 time.asctime(), time.ctime() and time.strftime() functions will now format

1851 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1852 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1853 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

2881 with a non-empty format string. This is an effort to future-proof user
2882 code. If a derived class does not currently implement __format__ but later
2883 adds its own __format__, it would most likely break user code that had
2884 supplied a format string. This will be changed to a DeprecationWaring in
2885 Python 3.3 and it will be an error in Python 3.4.

2889 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002898- Issue #4617: Previously it was illegal to delete a name from the local
2899 namespace if it occurs as a free variable in a nested block. This limitation
2900 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2901
Georg Brandl27a28582010-10-10 09:49:21 +00002902- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2903 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2904 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2905 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002940- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002941 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002942 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002943 replacement for old handle_accept() and avoids the user to call accept()

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003050- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003051 it possible for the user to create self-referencing ordered dictionaries which
3052 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003053 approach of using weakref proxies so that reference cycles never get created
3054 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00003097 * Update the seed() method to use all of the bits in a string instead of just
3098 the hash value. This makes better use of the seed value and assures the
3099 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003101 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3102 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3103 which has a slight bias whenever n is not a power of two. Issue #9025.

3256 return characters from the full Unicode range, even on narrow unicode builds
3257 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3258 in Python is that unicodedata.numeric() now returns the correct value for
3259 large code points, and repr() may consider more characters as printable.
3260
Victor Stinner6c00c142010-08-17 23:37:11 +00003261- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Victor Stinner47fcb5b2010-08-13 23:59:58 +00003277- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003278 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3279 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00003285- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3286 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00003287

3294 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003295
Georg Brandl649971e2010-09-05 17:06:50 +00003296- Issue #9416: Fix some issues with complex formatting where the output with no
3297 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003298
3299 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3300 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3641 the number of bytes specified by the start byte. E.g.:

3643 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3644 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3645 returned a single u'\ufffd'.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003717- Issue #8748: Fix two issues with comparisons between complex and integer
3718 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003719 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3720 (2) The comparison raised an OverflowError for large integers, leading to
3721 unpredictable exceptions when combining integers and complex objects in sets

4052 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4053 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004054 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00004161 applications that use a lot of regular expressions and limits the impact of
4162 the performance hit anytime the cache is exceeded.

4573 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4574 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004576- Issue #2531: Comparison operations between floats and Decimal instances now
4577 return a result based on the numeric values of the operands; previously they
4578 returned an arbitrary result based on the relative ordering of id(float) and
4579 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4580 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004584- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004585 argument `-` which tells it to read files to compile from stdin. Each line is
4586 read on demand and the named file is compiled immediately. (Original patch by
4587 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004589- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004593- Comparisons using one of <, <=, >, >= between a complex instance and a
4594 Fractions instance now raise TypeError instead of returning True/False. This
4595 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4596 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004639- The internals of the subprocess module on POSIX systems have been replaced by
4640 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4641 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004643- subprocess.Popen now has restore_signals and start_new_session features. The
4644 default of restore_signals=True is a new behavior compared to earlier Python
4645 versions. This means that signals such as SIGPIPE are not ignored by default
4646 in subprocesses launched by Python (Issue #1652).

Brett Cannon69194272009-07-20 04:23:48 +00005077- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00005078 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
5079 PyPycLoader inherit from this class and provide implementations in relation to
5080 other methods required by the ABCs.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005139- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005140 compared to other unix systems. In particular, os.getgroups() does not reflect
5141 any changes made using os.setgroups() but basicly always returns the same
5142 information as the id command. os.getgroups() can now return more than 16
5143 groups on MacOSX.

5169 Prior to this change, timezone adjustment in utctimetuple() could produce
5170 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

5174 directive. When the ``%z`` directive is present in the format string, an
5175 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5176 ``datetime.timezone`` instance constructed from the parsed offset. If both
5177 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5178 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005181 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5182 ``datetime.timezone``, return fixed name and UTC offset from their
5183 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5184 returns ``None``. A class attribute, ``utc`` contains an instance
5185 representing the UTC timezone. Original patch by Rafe Kaplan.

5202 with an improved 'binary-split' algorithm that uses fewer multiplications and
5203 allows many of the multiplications to be performed using plain C integer
5204 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

5211 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005212 the result is now always correctly rounded, and is equivalent to ``td /

Eric Smith63376222009-05-05 14:04:18 +00005802- Issue #5920: For float.__format__, change the behavior with the

5804 to be like 'g' but with at least one decimal point and with a
5805 default precision of 12. Previously, the behavior the same but with
5806 a default precision of 6. This more closely matches str(), and
5807 reduces surprises when adding alignment flags to the empty
5808 presentation type. This also affects the new complex.__format__ in
5809 the same way.

R. David Murrayb18500d2009-05-04 22:59:07 +00005813- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5814 shadowed by classtype's, even if it was None. property now
5815 inserts the __doc__ into the subclass instance __dict__.
5816
Antoine Pitrou244651a2009-05-04 18:56:13 +00005817- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00005822- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5823 received a new method, detach(). detach() disconnects the underlying stream
5824 from the buffer or text IO and returns it.
5825
Mark Dickinson33841c32009-05-01 15:37:04 +00005826- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5827 floats with absolute value over 1e50. Also remove length
5828 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5829 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00005831- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005832 format(complex(1, 2./3), '.5') now produces a sensible result.
5833
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005834- Issue #5864: Fix empty format code formatting for floats so that it
5835 never gives more than the requested number of significant digits.
5836
Eric Smith6dc46f52009-04-27 20:39:49 +00005837- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

5848 z involves nans, infs or negative zeros.
5849
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005850- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005851
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005852- Issue #1869 (and many duplicates): make round(x, n) correctly
5853 rounded for a float x, by using the decimal <-> binary conversions
5854 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5855 consistently agrees with format(x, '.2f').
5856
Benjamin Petersonae937c02009-04-18 20:54:08 +00005857- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5858 some builtin types.
5859
Eric Smith0923d1d2009-04-16 20:16:10 +00005860- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5861
Eric Smith35e84722009-04-16 20:21:28 +00005862- Issue #5515: str.format() type 'n' combined with commas and leading
5863 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005864
5865- Implement PEP 378, Format Specifier for Thousands Separator, for
5866 floats.
5867
Mark Dickinson3370cce2009-04-17 22:40:53 +00005868- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005869 1e11, not 1e12. This avoids printing 13 significant digits in
5870 situations where only 12 of them are correct. Example problem
5871 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5872 long time.)
5873
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005874- Issue #1580: On most platforms, use a 'short' float repr: for a
5875 finite float x, repr(x) now outputs a string based on the shortest
5876 sequence of decimal digits that rounds to x. Previous behaviour was
5877 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005878 Another minor difference is that the new repr switches to
5879 exponential notation at 1e16 instead of the previous 1e17; this
5880 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005881
5882 There's a new sys attribute sys.float_repr_style, which takes
5883 the value 'short' to indicate that we're using short float repr,
5884 and 'legacy' if the short float repr isn't available for one
5885 reason or another.
5886
5887 The float repr change involves incorporating David Gay's 'perfect
5888 rounding' code into the Python core (it's in Python/dtoa.c). As a
5889 secondary consequence, all string-to-float and float-to-string
5890 conversions (including all float formatting operations) will be
5891 correctly rounded on these platforms.
5892
Georg Brandl5f90d792010-08-01 22:31:05 +00005893 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005894 this change does not apply.
5895
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005896- Issue #5759: float() didn't call __float__ on str subclasses.
5897
Georg Brandlabc38772009-04-12 15:51:51 +00005898- The string.maketrans() function is deprecated; there is a new static method
5899 maketrans() on the bytes and bytearray classes. This removes confusion about
5900 the types string.maketrans() is supposed to work with, and mirrors the
5901 methods available on the str class.
5902
R. David Murraydc6da8a2009-04-09 22:16:43 +00005903- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

5908
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005909- Issue #3739: The unicode-internal encoder now reports the number of characters

6070 untrackable objects are not tracked by the garbage collector. This can
6071 reduce the size of collections and therefore the garbage collection overhead
6072 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson87ec0852009-02-09 17:15:59 +00006195- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6196 it now forces its argument to double before testing for infinity.
6197
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006198- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6199 returns a non-number type.
6200
Benjamin Peterson87618552009-02-08 15:00:52 +00006201- Issue #5182: Removed memoryview.__str__.
6202
Mark Dickinsonc008a172009-02-01 13:59:22 +00006203- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6204 slot, the C API functions PyObject_Compare and PyUnicode_Compare and

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006207
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006208- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006209 were suppressing all exceptions. These include list() and bytearray().
6210
Mark Dickinson1124e712009-01-28 21:25:58 +00006211- Issue #4707: round(x, n) now returns an integer if x is an integer.
6212 Previously it returned a float.
6213
Antoine Pitroub52ec782009-01-25 16:34:23 +00006214- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6215 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6216 evaluation loop is compiled with a new dispatch mechanism which gives
6217 speedups of up to 20%, depending on the system, on various benchmarks.
6218
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006219- Issue #4874: Most builtin decoders now reject unicode input.

6227 optional module state data.
6228
Mark Dickinson8055afd2009-01-17 10:04:45 +00006229- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006230 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006231
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006232- Issue #4935: The overflow checking code in the expandtabs() method common
6233 to str, bytes and bytearray could be optimized away by the compiler, letting
6234 the interpreter segfault instead of raising an error.
6235
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006236- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6237 __next__ method.
6238
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006239- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6240 function no longer attempt to call the __long__ slot to convert an object
6241 to an integer. Only the __int__ and __trunc__ slots are examined.
6242
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006243- Issue #4893: Use NT threading on CE.
6244

6246
Antoine Pitrouab868312009-01-10 15:40:25 +00006247- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6248 common cases are optimized thanks to a dedicated fast path and a moderate
6249 amount of loop unrolling.
6250
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006251- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6252 collecting the oldest generation) so that allocating lots of objects without
6253 destroying them does not show quadratic performance. Based on a proposal by
6254 Martin von Löwis at
6255 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6256
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006257- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006258 having been closed (for instance, a read() call could return some
6259 previously buffered data). Patch by Dmitry Vasiliev.
6260
Antoine Pitrou05608432009-01-09 18:53:14 +00006261- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6262 flag to work properly. Furthermore, when specifying -u, the text stdout
6263 and stderr streams have line-by-line buffering enabled (the default being
6264 to buffer arbitrary chunks of data).
6265
Raymond Hettinger35631532009-01-09 03:58:09 +00006266- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6267 instead of ints (reducing its size from 4 to 8 times thereby reducing
6268 Python's overall memory).
6269
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006270- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6271 an existing .py counterpart, override the co_filename attributes of all
6272 code objects if the original filename is obsolete (which can happen if the
6273 file has been renamed, moved, or if it is accessed through different paths).
6274 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6275
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006276- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6277 one byte. Also fixes the meaning of len() so that it returns the number of
6278 items, rather than the size in bytes.
6279
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006280- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6281
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006282- Issue #4747: When the terminal does not use utf-8, executing a script with
6283 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6284
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006285- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6286 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006287
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006288- Issue #3680: Reference cycles created through a dict, set or deque iterator
6289 did not get collected.
6290
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006291- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6292 where the tp_hash and tp_dict slots are both NULL.
6293
Georg Brandlccc47b62008-12-28 11:44:14 +00006294- Issue #4759: None is now allowed as the first argument of
6295 bytearray.translate(). It was always allowed for bytes.translate().
6296
Skip Montanaro80072cb2008-12-23 03:51:14 +00006297- Added test case to ensure attempts to read from a file opened for writing
6298 fail.
6299
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006300- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00006302- Issue #2183: Simplify and optimize bytecode for list, dict and set
6303 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6304
Antoine Pitrou621601a2008-12-17 23:18:19 +00006305- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6306 print elapsed times, not only when some objects are uncollectable /
6307 unreachable. Original patch by Neil Schemenauer.
6308
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006309- Issue #3439: Add a bit_length method to int.
6310
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006311- Issue #2173: When getting device encoding, check that return value of
6312 nl_langinfo is not the empty string. This was causing silent build
6313 failures on OS X.
6314
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006315- Issue #4597: Fixed several opcodes that weren't always propagating
6316 exceptions.
6317
6318- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006319 context manager returns a value that cannot be converted to a bool.
6320
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006321- Issue #4445: Replace "sizeof(PyBytesObject)" with
6322 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6323 bytes instances. On a typical machine this saves 3 bytes of memory
6324 (on average) per allocation of a bytes instance.
6325
Christian Heimesa872de52008-12-05 08:26:55 +00006326- Issue #4533: File read operation was dreadfully slow due to a slowly
6327 growing read buffer. Fixed by using the same growth rate algorithm as
6328 Python 2.x.
6329
Antoine Pitrou5504e892008-12-06 21:27:53 +00006330- Issue #4509: Various issues surrounding resize of bytearray objects to
6331 which there are buffer exports (e.g. memoryview instances).
6332
Georg Brandlf9734072008-12-07 15:30:06 +00006333- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6334 method on file objects with closefd=False. The file descriptor is still
6335 kept open but the file object behaves like a closed file. The ``FileIO``
6336 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006337
Antoine Pitroubc420402008-12-07 20:14:49 +00006338- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6339 larger than 1.

6344
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006345- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6346 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6347 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6348 of using the replace error handler in PyUnicode_DecodeUTF8().

Guilherme Polo2a998fa2009-06-21 17:40:07 +00006953- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6954 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6955 the same behaviour as test_ttkguionly (and now also test_tk) which is to

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006959 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006960 from test support, which does the conversion.
