95
Antoine Pitrou5418ee02011-11-15 01:42:21 +010096- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
97 already accepts them).

Antoine Pitrou9a812cb2011-11-15 00:00:12 +010099- Issue #13389: Full garbage collection passes now clear the freelists for
100 list and dict objects. They already cleared other freelists in the

Ned Deily657b2de2011-06-28 19:51:30 -07001093- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1094 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1095 interpreter process. This could cause failures in non-Distutils subprocesses
1096 and was unreliable since tests or user programs could modify the interpreter
1097 environment after Distutils set it. Instead, have Distutils set the the
1098 deployment target only in the environment of each build subprocess. It is
1099 still possible to globally override the default by setting
1100 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1101 greater or equal to the default value, the value with which the interpreter

2230 keyword-only argument. The preceding positional argument was deprecated,
2231 so it made no sense to add filter as a positional argument.

2260 of HTTP 1.1.
Steven Bethardb0270112011-01-24 21:02:50 +00002261
2262- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00002263 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00002264 that for incoming headers which makes this behaviour now consistent in
2265 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00002361- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00002362 continuation line in the formatted value has no leading white space and looks
2363 like a header. Since Generator uses Header to format all headers, this check
2364 is made for all headers in any serialized message at serialization time. This
2365 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00002366
Antoine Pitrou67b212e2011-01-08 09:55:31 +00002367- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

Georg Brandl255abdd2011-01-16 14:17:26 +00002375 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00002376
Éric Araujof0ab5d62011-05-29 03:43:59 +02002377- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00002378 rfc2047-encoding header values with embedded newlines, leaving them without
2379 folding whitespace. It now uses the continuation_ws, as it does for

Victor Stinner3ec899f2011-01-08 16:37:47 +00002382- Issue #1777412, #10827: Changed the rules for 2-digit years. The
2383 time.asctime(), time.ctime() and time.strftime() functions will now format

2385 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
2386 supported by the OS. With Visual Studio or on Solaris, the year is limited to
2387 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

3420 with a non-empty format string. This is an effort to future-proof user
3421 code. If a derived class does not currently implement __format__ but later
3422 adds its own __format__, it would most likely break user code that had
3423 supplied a format string. This will be changed to a DeprecationWaring in
3424 Python 3.3 and it will be an error in Python 3.4.

3428 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

3438 namespace if it occurs as a free variable in a nested block. This limitation
3439 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3440
Georg Brandl27a28582010-10-10 09:49:21 +00003441- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3442 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3443 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3444 single character on UCS-2 builds.

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003589- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003590 it possible for the user to create self-referencing ordered dictionaries which
3591 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003592 approach of using weakref proxies so that reference cycles never get created
3593 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00003636 * Update the seed() method to use all of the bits in a string instead of just
3637 the hash value. This makes better use of the seed value and assures the
3638 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003640 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3641 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3642 which has a slight bias whenever n is not a power of two. Issue #9025.

3795 return characters from the full Unicode range, even on narrow unicode builds
3796 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3797 in Python is that unicodedata.numeric() now returns the correct value for
3798 large code points, and repr() may consider more characters as printable.

Victor Stinner47fcb5b2010-08-13 23:59:58 +00003816- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003817 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3818 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00003824- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3825 use PyUnicode_FromFormatV() to format the warning message.

3833 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003834
Georg Brandl649971e2010-09-05 17:06:50 +00003835- Issue #9416: Fix some issues with complex formatting where the output with no
3836 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003837
3838 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3839 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Georg Brandl62069d32010-07-31 08:56:11 +00004227- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
4228 TypeError instead of giving a DeprecationWarning when a float is parsed using
4229 the 'L' code (for long long). (All other integer codes already raise

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004256- Issue #8748: Fix two issues with comparisons between complex and integer
4257 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00004258 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
4259 (2) The comparison raised an OverflowError for large integers, leading to
4260 unpredictable exceptions when combining integers and complex objects in sets
4261 or dicts.

Victor Stinner0964ee12010-04-30 16:48:45 +00004285- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of

5102 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00005103
5104 >>> Decimal(1.1)
5105 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00005110- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5111 InvalidOperation instead of returning False. (Comparisons involving a quiet
5112 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5113 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00005115- Issue #2531: Comparison operations between floats and Decimal instances now
5116 return a result based on the numeric values of the operands; previously they
5117 returned an arbitrary result based on the relative ordering of id(float) and
5118 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
5119 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00005123- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00005124 argument `-` which tells it to read files to compile from stdin. Each line is
5125 read on demand and the named file is compiled immediately. (Original patch by
5126 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00005132- Comparisons using one of <, <=, >, >= between a complex instance and a
5133 Fractions instance now raise TypeError instead of returning True/False. This
5134 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5135 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00005178- The internals of the subprocess module on POSIX systems have been replaced by
5179 an extension module (_posixsubprocess) so that the fork()+exec() can be done
5180 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00005182- subprocess.Popen now has restore_signals and start_new_session features. The
5183 default of restore_signals=True is a new behavior compared to earlier Python
5184 versions. This means that signals such as SIGPIPE are not ignored by default
5185 in subprocesses launched by Python (Issue #1652).

5272 position when calling `truncate()`. It would previously change the file
5273 position to the given argument, which goes against the tradition of

5278 archive. The new implementation is significantly faster and can be wrapped in
5279 a :class:`io.BufferedReader` object for more speedups. It also solves an
5280 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00005616- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00005617 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
5618 PyPycLoader inherit from this class and provide implementations in relation to
5619 other methods required by the ABCs.

Brett Cannon64ef00f2009-07-20 03:19:18 +00005621- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
5622 the documentation said it did even though the code in PyLoader relied on the
5623 abstract method required by ResourceLoader.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005678- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005679 compared to other unix systems. In particular, os.getgroups() does not reflect
5680 any changes made using os.setgroups() but basicly always returns the same
5681 information as the id command. os.getgroups() can now return more than 16
5682 groups on MacOSX.

5708 Prior to this change, timezone adjustment in utctimetuple() could produce
5709 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

5713 directive. When the ``%z`` directive is present in the format string, an
5714 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5715 ``datetime.timezone`` instance constructed from the parsed offset. If both
5716 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5717 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005720 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5721 ``datetime.timezone``, return fixed name and UTC offset from their
5722 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5723 returns ``None``. A class attribute, ``utc`` contains an instance
5724 representing the UTC timezone. Original patch by Rafe Kaplan.

5750 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005751 the result is now always correctly rounded, and is equivalent to ``td /

Mark Hammond5a607a32009-05-06 08:04:54 +00006337- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
6338 in all operations, including splitdrive, split, etc. splitunc() now issues
6339 a PendingDeprecation warning.
6340
Eric Smith63376222009-05-05 14:04:18 +00006341- Issue #5920: For float.__format__, change the behavior with the
6342 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6343 to be like 'g' but with at least one decimal point and with a
6344 default precision of 12. Previously, the behavior the same but with
6345 a default precision of 6. This more closely matches str(), and
6346 reduces surprises when adding alignment flags to the empty
6347 presentation type. This also affects the new complex.__format__ in
6348 the same way.
6349
Martin v. Löwis011e8422009-05-05 04:43:17 +00006350- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
6351
R. David Murrayb18500d2009-05-04 22:59:07 +00006352- Issue #5890: in subclasses of 'property' the __doc__ attribute was
6353 shadowed by classtype's, even if it was None. property now
6354 inserts the __doc__ into the subclass instance __dict__.
6355
Antoine Pitrou244651a2009-05-04 18:56:13 +00006356- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00006361- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6362 received a new method, detach(). detach() disconnects the underlying stream
6363 from the buffer or text IO and returns it.
6364
Mark Dickinson33841c32009-05-01 15:37:04 +00006365- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6366 floats with absolute value over 1e50. Also remove length
6367 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6368 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006369
Eric Smith741191f2009-05-06 13:08:15 +00006370- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006371 format(complex(1, 2./3), '.5') now produces a sensible result.
6372
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006373- Issue #5864: Fix empty format code formatting for floats so that it
6374 never gives more than the requested number of significant digits.
6375
Eric Smith6dc46f52009-04-27 20:39:49 +00006376- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +00006386- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6387 z involves nans, infs or negative zeros.
6388
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006389- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006390
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006391- Issue #1869 (and many duplicates): make round(x, n) correctly
6392 rounded for a float x, by using the decimal <-> binary conversions
6393 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6394 consistently agrees with format(x, '.2f').
6395
Benjamin Petersonae937c02009-04-18 20:54:08 +00006396- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6397 some builtin types.
6398
Eric Smith0923d1d2009-04-16 20:16:10 +00006399- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6400
Eric Smith35e84722009-04-16 20:21:28 +00006401- Issue #5515: str.format() type 'n' combined with commas and leading
6402 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006403
6404- Implement PEP 378, Format Specifier for Thousands Separator, for
6405 floats.
6406
Mark Dickinson3370cce2009-04-17 22:40:53 +00006407- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006408 1e11, not 1e12. This avoids printing 13 significant digits in
6409 situations where only 12 of them are correct. Example problem
6410 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6411 long time.)
6412
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006413- Issue #1580: On most platforms, use a 'short' float repr: for a
6414 finite float x, repr(x) now outputs a string based on the shortest
6415 sequence of decimal digits that rounds to x. Previous behaviour was
6416 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006417 Another minor difference is that the new repr switches to
6418 exponential notation at 1e16 instead of the previous 1e17; this
6419 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006420
6421 There's a new sys attribute sys.float_repr_style, which takes
6422 the value 'short' to indicate that we're using short float repr,
6423 and 'legacy' if the short float repr isn't available for one
6424 reason or another.
6425
6426 The float repr change involves incorporating David Gay's 'perfect
6427 rounding' code into the Python core (it's in Python/dtoa.c). As a
6428 secondary consequence, all string-to-float and float-to-string
6429 conversions (including all float formatting operations) will be
6430 correctly rounded on these platforms.
6431
Georg Brandl5f90d792010-08-01 22:31:05 +00006432 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006433 this change does not apply.
6434
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006435- Issue #5759: float() didn't call __float__ on str subclasses.
6436
Georg Brandlabc38772009-04-12 15:51:51 +00006437- The string.maketrans() function is deprecated; there is a new static method
6438 maketrans() on the bytes and bytearray classes. This removes confusion about
6439 the types string.maketrans() is supposed to work with, and mirrors the
6440 methods available on the str class.
6441
R. David Murraydc6da8a2009-04-09 22:16:43 +00006442- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

6444
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006445- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006446 to avoid compiler warnings.
6447
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006448- Issue #3739: The unicode-internal encoder now reports the number of characters

Benjamin Peterson8f76b492009-04-03 22:22:42 +00006586- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
6587
Benjamin Peterson7fe98532009-04-02 00:33:55 +00006588- Issue #5499: The 'c' code for argument parsing functions now only accepts a

6607
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006608- Issue #4688: Add a heuristic so that tuples and dicts containing only
6609 untrackable objects are not tracked by the garbage collector. This can
6610 reduce the size of collections and therefore the garbage collection overhead
6611 on long-running programs, depending on their particular use of datatypes.

6618 2**15 for the internal representation of integers, for performance
6619 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6620 --enable-big-digits option to configure, which overrides the
6621 default. Add sys.int_info structseq to provide information about
6622 the internal format.

Mark Dickinson081dfee2009-03-18 14:47:41 +00006624- Issue #4474: PyUnicode_FromWideChar now converts characters outside
6625 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
6626 and sizeof(Py_UNICODE) == 2.
6627
Eric Smith8ec90442009-03-14 12:29:34 +00006628- Issue #5237: Allow auto-numbered fields in str.format(). For

Mark Dickinson87ec0852009-02-09 17:15:59 +00006734- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6735 it now forces its argument to double before testing for infinity.
6736
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006737- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6738 returns a non-number type.
6739
Benjamin Peterson87618552009-02-08 15:00:52 +00006740- Issue #5182: Removed memoryview.__str__.
6741
Mark Dickinsonc008a172009-02-01 13:59:22 +00006742- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6743 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006744 the type definition cmpfunc. The tp_compare slot has been renamed

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006746
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006747- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006748 were suppressing all exceptions. These include list() and bytearray().
6749
Mark Dickinson1124e712009-01-28 21:25:58 +00006750- Issue #4707: round(x, n) now returns an integer if x is an integer.
6751 Previously it returned a float.
6752
Antoine Pitroub52ec782009-01-25 16:34:23 +00006753- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6754 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6755 evaluation loop is compiled with a new dispatch mechanism which gives
6756 speedups of up to 20%, depending on the system, on various benchmarks.
6757
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006758- Issue #4874: Most builtin decoders now reject unicode input.

6766 optional module state data.
6767
Mark Dickinson8055afd2009-01-17 10:04:45 +00006768- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006769 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006770
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006771- Issue #4935: The overflow checking code in the expandtabs() method common
6772 to str, bytes and bytearray could be optimized away by the compiler, letting
6773 the interpreter segfault instead of raising an error.
6774
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006775- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6776 __next__ method.
6777
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006778- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6779 function no longer attempt to call the __long__ slot to convert an object
6780 to an integer. Only the __int__ and __trunc__ slots are examined.
6781
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006782- Issue #4893: Use NT threading on CE.

6785
Antoine Pitrouab868312009-01-10 15:40:25 +00006786- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6787 common cases are optimized thanks to a dedicated fast path and a moderate
6788 amount of loop unrolling.
6789
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006790- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6791 collecting the oldest generation) so that allocating lots of objects without
6792 destroying them does not show quadratic performance. Based on a proposal by
6793 Martin von Löwis at
6794 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6795
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006796- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006797 having been closed (for instance, a read() call could return some
6798 previously buffered data). Patch by Dmitry Vasiliev.
6799
Antoine Pitrou05608432009-01-09 18:53:14 +00006800- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6801 flag to work properly. Furthermore, when specifying -u, the text stdout
6802 and stderr streams have line-by-line buffering enabled (the default being
6803 to buffer arbitrary chunks of data).
6804
Raymond Hettinger35631532009-01-09 03:58:09 +00006805- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6806 instead of ints (reducing its size from 4 to 8 times thereby reducing
6807 Python's overall memory).
6808
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006809- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6810 an existing .py counterpart, override the co_filename attributes of all
6811 code objects if the original filename is obsolete (which can happen if the
6812 file has been renamed, moved, or if it is accessed through different paths).
6813 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6814
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006815- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6816 one byte. Also fixes the meaning of len() so that it returns the number of
6817 items, rather than the size in bytes.
6818
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006819- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6820
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006821- Issue #4747: When the terminal does not use utf-8, executing a script with
6822 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6823
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006824- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6825 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006826
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006827- Issue #3680: Reference cycles created through a dict, set or deque iterator
6828 did not get collected.
6829
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006830- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6831 where the tp_hash and tp_dict slots are both NULL.
6832
Georg Brandlccc47b62008-12-28 11:44:14 +00006833- Issue #4759: None is now allowed as the first argument of
6834 bytearray.translate(). It was always allowed for bytes.translate().
6835
Skip Montanaro80072cb2008-12-23 03:51:14 +00006836- Added test case to ensure attempts to read from a file opened for writing
6837 fail.
6838
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006839- Issue #3106: Speedup some comparisons (str/str and int/int).

6842 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6843
Antoine Pitrou621601a2008-12-17 23:18:19 +00006844- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6845 print elapsed times, not only when some objects are uncollectable /
6846 unreachable. Original patch by Neil Schemenauer.
6847
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006848- Issue #3439: Add a bit_length method to int.
6849
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006850- Issue #2173: When getting device encoding, check that return value of
6851 nl_langinfo is not the empty string. This was causing silent build
6852 failures on OS X.
6853
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006854- Issue #4597: Fixed several opcodes that weren't always propagating
6855 exceptions.
6856
6857- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006858 context manager returns a value that cannot be converted to a bool.
6859
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006860- Issue #4445: Replace "sizeof(PyBytesObject)" with
6861 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6862 bytes instances. On a typical machine this saves 3 bytes of memory
6863 (on average) per allocation of a bytes instance.
6864
Christian Heimesa872de52008-12-05 08:26:55 +00006865- Issue #4533: File read operation was dreadfully slow due to a slowly
6866 growing read buffer. Fixed by using the same growth rate algorithm as
6867 Python 2.x.
6868
Antoine Pitrou5504e892008-12-06 21:27:53 +00006869- Issue #4509: Various issues surrounding resize of bytearray objects to
6870 which there are buffer exports (e.g. memoryview instances).
6871
Georg Brandlf9734072008-12-07 15:30:06 +00006872- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6873 method on file objects with closefd=False. The file descriptor is still
6874 kept open but the file object behaves like a closed file. The ``FileIO``
6875 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006876
Antoine Pitroubc420402008-12-07 20:14:49 +00006877- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6878 larger than 1.

6883
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006884- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6885 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6886 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6887 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00007489- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
7490 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00007492- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
7493 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
7494 the same behaviour as test_ttkguionly (and now also test_tk) which is to
7495 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00007497- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00007498 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00007499 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00007501- Issue #5083: New 'gui' resource for regrtest.
