Ned Deily657b2de2011-06-28 19:51:30 -0700181- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
182 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
183 interpreter process. This could cause failures in non-Distutils subprocesses
184 and was unreliable since tests or user programs could modify the interpreter
185 environment after Distutils set it. Instead, have Distutils set the the
186 deployment target only in the environment of each build subprocess. It is
187 still possible to globally override the default by setting
188 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
189 greater or equal to the default value, the value with which the interpreter
190 was built.

894 keyword-only argument. The preceding positional argument was deprecated,
895 so it made no sense to add filter as a positional argument.

Victor Stinner4ee65a92011-01-22 10:30:29 +0000910 filenames, at bootstrap, if the codec registry is not ready yet. It is still

923 encoding. This is the preferred encoding of PEP 3333 and the base encoding
924 of HTTP 1.1.
925
Armin Ronacher59531282011-01-22 13:44:22 +0000926- To match the behaviour of HTTP server, the HTTP client library now also
927 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
928 that for incoming headers which makes this behaviour now consistent in
929 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001029- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001030 continuation line in the formatted value has no leading white space and looks
1031 like a header. Since Generator uses Header to format all headers, this check
1032 is made for all headers in any serialized message at serialization time. This
1033 provides protection against header injection attacks.

Georg Brandl255abdd2011-01-16 14:17:26 +00001043 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001044
Éric Araujof0ab5d62011-05-29 03:43:59 +02001045- email.header.Header was incorrectly encoding folding whitespace when

1047 folding whitespace. It now uses the continuation_ws, as it does for
1048 continuation lines that it creates itself.

1051 time.asctime(), time.ctime() and time.strftime() functions will now format

1053 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1054 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1055 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

2081 with a non-empty format string. This is an effort to future-proof user
2082 code. If a derived class does not currently implement __format__ but later
2083 adds its own __format__, it would most likely break user code that had
2084 supplied a format string. This will be changed to a DeprecationWaring in
2085 Python 3.3 and it will be an error in Python 3.4.

2089 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

2099 namespace if it occurs as a free variable in a nested block. This limitation
2100 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2101
Georg Brandl27a28582010-10-10 09:49:21 +00002102- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2103 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2104 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2105 single character on UCS-2 builds.

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002250- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002251 it possible for the user to create self-referencing ordered dictionaries which
2252 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002253 approach of using weakref proxies so that reference cycles never get created
2254 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00002297 * Update the seed() method to use all of the bits in a string instead of just
2298 the hash value. This makes better use of the seed value and assures the
2299 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002301 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2302 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2303 which has a slight bias whenever n is not a power of two. Issue #9025.

2305 * Improved documentation of arguments to randrange(). Issue #9379.

2326 guaranteed to exist in all Python implementations and the names of hash
2327 algorithms available in the current process.

2456 return characters from the full Unicode range, even on narrow unicode builds
2457 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2458 in Python is that unicodedata.numeric() now returns the correct value for
2459 large code points, and repr() may consider more characters as printable.

Victor Stinner47fcb5b2010-08-13 23:59:58 +00002477- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00002478 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2479 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00002485- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2486 use PyUnicode_FromFormatV() to format the warning message.

2494 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002495
Georg Brandl649971e2010-09-05 17:06:50 +00002496- Issue #9416: Fix some issues with complex formatting where the output with no
2497 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002498
2499 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2500 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002917- Issue #8748: Fix two issues with comparisons between complex and integer
2918 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002919 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2920 (2) The comparison raised an OverflowError for large integers, leading to
2921 unpredictable exceptions when combining integers and complex objects in sets
2922 or dicts.

Victor Stinner0964ee12010-04-30 16:48:45 +00002946- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of

3252 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3253 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003254 to match the behaviour of the other integer format codes.

3362 the performance hit anytime the cache is exceeded.

3763 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00003764
3765 >>> Decimal(1.1)
3766 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00003771- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3772 InvalidOperation instead of returning False. (Comparisons involving a quiet
3773 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3774 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00003776- Issue #2531: Comparison operations between floats and Decimal instances now
3777 return a result based on the numeric values of the operands; previously they
3778 returned an arbitrary result based on the relative ordering of id(float) and
3779 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3780 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00003784- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003785 argument `-` which tells it to read files to compile from stdin. Each line is
3786 read on demand and the named file is compiled immediately. (Original patch by
3787 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00003793- Comparisons using one of <, <=, >, >= between a complex instance and a
3794 Fractions instance now raise TypeError instead of returning True/False. This
3795 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3796 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003839- The internals of the subprocess module on POSIX systems have been replaced by
3840 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3841 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00003843- subprocess.Popen now has restore_signals and start_new_session features. The
3844 default of restore_signals=True is a new behavior compared to earlier Python
3845 versions. This means that signals such as SIGPIPE are not ignored by default
3846 in subprocesses launched by Python (Issue #1652).

3933 position when calling `truncate()`. It would previously change the file
3934 position to the given argument, which goes against the tradition of

3939 archive. The new implementation is significantly faster and can be wrapped in
3940 a :class:`io.BufferedReader` object for more speedups. It also solves an
3941 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00004277- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004278 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4279 PyPycLoader inherit from this class and provide implementations in relation to
4280 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004281
Brett Cannon64ef00f2009-07-20 03:19:18 +00004282- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4283 the documentation said it did even though the code in PyLoader relied on the
4284 abstract method required by ResourceLoader.
4285
Georg Brandl62069d32010-07-31 08:56:11 +00004286- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004339- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004340 compared to other unix systems. In particular, os.getgroups() does not reflect
4341 any changes made using os.setgroups() but basicly always returns the same
4342 information as the id command. os.getgroups() can now return more than 16
4343 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00004368- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4369 Prior to this change, timezone adjustment in utctimetuple() could produce
4370 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

4374 directive. When the ``%z`` directive is present in the format string, an
4375 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4376 ``datetime.timezone`` instance constructed from the parsed offset. If both
4377 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4378 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004380- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004381 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4382 ``datetime.timezone``, return fixed name and UTC offset from their
4383 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4384 returns ``None``. A class attribute, ``utc`` contains an instance
4385 representing the UTC timezone. Original patch by Rafe Kaplan.

4402 with an improved 'binary-split' algorithm that uses fewer multiplications and
4403 allows many of the multiplications to be performed using plain C integer
4404 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00004410- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4411 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004412 the result is now always correctly rounded, and is equivalent to ``td /
4413 timedelta(seconds=1)``.

4422 integer format code, struct.pack first attempts to convert the non-integer

Mark Hammond5a607a32009-05-06 08:04:54 +00004998- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4999 in all operations, including splitdrive, split, etc. splitunc() now issues
5000 a PendingDeprecation warning.
5001
Eric Smith63376222009-05-05 14:04:18 +00005002- Issue #5920: For float.__format__, change the behavior with the
5003 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5004 to be like 'g' but with at least one decimal point and with a
5005 default precision of 12. Previously, the behavior the same but with
5006 a default precision of 6. This more closely matches str(), and
5007 reduces surprises when adding alignment flags to the empty
5008 presentation type. This also affects the new complex.__format__ in
5009 the same way.
5010
Martin v. Löwis011e8422009-05-05 04:43:17 +00005011- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5012
R. David Murrayb18500d2009-05-04 22:59:07 +00005013- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5014 shadowed by classtype's, even if it was None. property now
5015 inserts the __doc__ into the subclass instance __dict__.
5016
Antoine Pitrou244651a2009-05-04 18:56:13 +00005017- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00005022- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5023 received a new method, detach(). detach() disconnects the underlying stream
5024 from the buffer or text IO and returns it.
5025
Mark Dickinson33841c32009-05-01 15:37:04 +00005026- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5027 floats with absolute value over 1e50. Also remove length
5028 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5029 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005030
Eric Smith741191f2009-05-06 13:08:15 +00005031- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005032 format(complex(1, 2./3), '.5') now produces a sensible result.
5033
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005034- Issue #5864: Fix empty format code formatting for floats so that it
5035 never gives more than the requested number of significant digits.
5036
Eric Smith6dc46f52009-04-27 20:39:49 +00005037- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +00005047- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5048 z involves nans, infs or negative zeros.
5049
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005050- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005051
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005052- Issue #1869 (and many duplicates): make round(x, n) correctly
5053 rounded for a float x, by using the decimal <-> binary conversions
5054 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5055 consistently agrees with format(x, '.2f').
5056
Benjamin Petersonae937c02009-04-18 20:54:08 +00005057- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5058 some builtin types.
5059
Eric Smith0923d1d2009-04-16 20:16:10 +00005060- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5061
Eric Smith35e84722009-04-16 20:21:28 +00005062- Issue #5515: str.format() type 'n' combined with commas and leading
5063 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005064
5065- Implement PEP 378, Format Specifier for Thousands Separator, for
5066 floats.
5067
Mark Dickinson3370cce2009-04-17 22:40:53 +00005068- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005069 1e11, not 1e12. This avoids printing 13 significant digits in
5070 situations where only 12 of them are correct. Example problem
5071 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5072 long time.)
5073
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005074- Issue #1580: On most platforms, use a 'short' float repr: for a
5075 finite float x, repr(x) now outputs a string based on the shortest
5076 sequence of decimal digits that rounds to x. Previous behaviour was
5077 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005078 Another minor difference is that the new repr switches to
5079 exponential notation at 1e16 instead of the previous 1e17; this
5080 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005081
5082 There's a new sys attribute sys.float_repr_style, which takes
5083 the value 'short' to indicate that we're using short float repr,
5084 and 'legacy' if the short float repr isn't available for one
5085 reason or another.
5086
5087 The float repr change involves incorporating David Gay's 'perfect
5088 rounding' code into the Python core (it's in Python/dtoa.c). As a
5089 secondary consequence, all string-to-float and float-to-string
5090 conversions (including all float formatting operations) will be
5091 correctly rounded on these platforms.
5092
Georg Brandl5f90d792010-08-01 22:31:05 +00005093 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005094 this change does not apply.
5095
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005096- Issue #5759: float() didn't call __float__ on str subclasses.
5097
Georg Brandlabc38772009-04-12 15:51:51 +00005098- The string.maketrans() function is deprecated; there is a new static method
5099 maketrans() on the bytes and bytearray classes. This removes confusion about
5100 the types string.maketrans() is supposed to work with, and mirrors the
5101 methods available on the str class.
5102
R. David Murraydc6da8a2009-04-09 22:16:43 +00005103- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Benjamin Peterson8f76b492009-04-03 22:22:42 +00005247- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
5248
Benjamin Peterson7fe98532009-04-02 00:33:55 +00005249- Issue #5499: The 'c' code for argument parsing functions now only accepts a

5268
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005269- Issue #4688: Add a heuristic so that tuples and dicts containing only
5270 untrackable objects are not tracked by the garbage collector. This can
5271 reduce the size of collections and therefore the garbage collection overhead
5272 on long-running programs, depending on their particular use of datatypes.

5279 2**15 for the internal representation of integers, for performance
5280 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5281 --enable-big-digits option to configure, which overrides the
5282 default. Add sys.int_info structseq to provide information about
5283 the internal format.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005395- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5396 it now forces its argument to double before testing for infinity.
5397
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005398- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5399 returns a non-number type.
5400
Benjamin Peterson87618552009-02-08 15:00:52 +00005401- Issue #5182: Removed memoryview.__str__.
5402
Mark Dickinsonc008a172009-02-01 13:59:22 +00005403- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5404 slot, the C API functions PyObject_Compare and PyUnicode_Compare and

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005407
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005408- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005409 were suppressing all exceptions. These include list() and bytearray().
5410
Mark Dickinson1124e712009-01-28 21:25:58 +00005411- Issue #4707: round(x, n) now returns an integer if x is an integer.
5412 Previously it returned a float.
5413
Antoine Pitroub52ec782009-01-25 16:34:23 +00005414- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5415 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5416 evaluation loop is compiled with a new dispatch mechanism which gives
5417 speedups of up to 20%, depending on the system, on various benchmarks.
5418
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005419- Issue #4874: Most builtin decoders now reject unicode input.

5427 optional module state data.
5428
Mark Dickinson8055afd2009-01-17 10:04:45 +00005429- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005430 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005431
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005432- Issue #4935: The overflow checking code in the expandtabs() method common
5433 to str, bytes and bytearray could be optimized away by the compiler, letting
5434 the interpreter segfault instead of raising an error.
5435
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005436- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5437 __next__ method.
5438
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005439- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5440 function no longer attempt to call the __long__ slot to convert an object
5441 to an integer. Only the __int__ and __trunc__ slots are examined.
5442
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005443- Issue #4893: Use NT threading on CE.
5444

5446
Antoine Pitrouab868312009-01-10 15:40:25 +00005447- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5448 common cases are optimized thanks to a dedicated fast path and a moderate
5449 amount of loop unrolling.
5450
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005451- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5452 collecting the oldest generation) so that allocating lots of objects without
5453 destroying them does not show quadratic performance. Based on a proposal by
5454 Martin von Löwis at
5455 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5456
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005457- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005458 having been closed (for instance, a read() call could return some
5459 previously buffered data). Patch by Dmitry Vasiliev.
5460
Antoine Pitrou05608432009-01-09 18:53:14 +00005461- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5462 flag to work properly. Furthermore, when specifying -u, the text stdout
5463 and stderr streams have line-by-line buffering enabled (the default being
5464 to buffer arbitrary chunks of data).
5465
Raymond Hettinger35631532009-01-09 03:58:09 +00005466- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5467 instead of ints (reducing its size from 4 to 8 times thereby reducing
5468 Python's overall memory).
5469
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005470- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5471 an existing .py counterpart, override the co_filename attributes of all
5472 code objects if the original filename is obsolete (which can happen if the
5473 file has been renamed, moved, or if it is accessed through different paths).
5474 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5475
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005476- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5477 one byte. Also fixes the meaning of len() so that it returns the number of
5478 items, rather than the size in bytes.
5479
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005480- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5481
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005482- Issue #4747: When the terminal does not use utf-8, executing a script with
5483 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5484
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005485- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5486 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005487
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005488- Issue #3680: Reference cycles created through a dict, set or deque iterator
5489 did not get collected.
5490
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005491- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5492 where the tp_hash and tp_dict slots are both NULL.
5493
Georg Brandlccc47b62008-12-28 11:44:14 +00005494- Issue #4759: None is now allowed as the first argument of
5495 bytearray.translate(). It was always allowed for bytes.translate().
5496
Skip Montanaro80072cb2008-12-23 03:51:14 +00005497- Added test case to ensure attempts to read from a file opened for writing
5498 fail.
5499
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005500- Issue #3106: Speedup some comparisons (str/str and int/int).

5503 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5504
Antoine Pitrou621601a2008-12-17 23:18:19 +00005505- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5506 print elapsed times, not only when some objects are uncollectable /
5507 unreachable. Original patch by Neil Schemenauer.
5508
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005509- Issue #3439: Add a bit_length method to int.
5510
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005511- Issue #2173: When getting device encoding, check that return value of
5512 nl_langinfo is not the empty string. This was causing silent build
5513 failures on OS X.
5514
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005515- Issue #4597: Fixed several opcodes that weren't always propagating
5516 exceptions.
5517
5518- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005519 context manager returns a value that cannot be converted to a bool.
5520
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005521- Issue #4445: Replace "sizeof(PyBytesObject)" with
5522 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5523 bytes instances. On a typical machine this saves 3 bytes of memory
5524 (on average) per allocation of a bytes instance.
5525
Christian Heimesa872de52008-12-05 08:26:55 +00005526- Issue #4533: File read operation was dreadfully slow due to a slowly
5527 growing read buffer. Fixed by using the same growth rate algorithm as
5528 Python 2.x.
5529
Antoine Pitrou5504e892008-12-06 21:27:53 +00005530- Issue #4509: Various issues surrounding resize of bytearray objects to
5531 which there are buffer exports (e.g. memoryview instances).
5532
Georg Brandlf9734072008-12-07 15:30:06 +00005533- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5534 method on file objects with closefd=False. The file descriptor is still
5535 kept open but the file object behaves like a closed file. The ``FileIO``
5536 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005537
Antoine Pitroubc420402008-12-07 20:14:49 +00005538- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5539 larger than 1.

5544
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005545- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5546 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5547 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5548 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00006150- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6151 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00006153- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6154 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6155 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6156 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00006158- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006159 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006160 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00006162- Issue #5083: New 'gui' resource for regrtest.
