Benjamin Peterson5c4bfc42010-10-12 22:57:59 +0000932- Issue #10068: Global objects which have reference cycles with their module's
933 dict are now cleared again. This causes issue #7140 to appear again.
934
Victor Stinner257d38f2010-10-09 10:12:11 +0000935- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()

Georg Brandl27a28582010-10-10 09:49:21 +0000938- ast.literal_eval() can now handle negative numbers. It is also a little more
939 liberal in what it accepts without compromising the safety of the evaluation.
940 For example, 3j+4 and 3+4+5 are both accepted.

969 Py_Initialize().
970
Georg Brandl27a28582010-10-10 09:49:21 +0000971- All SyntaxErrors now have a column offset and therefore a caret when the error

976
Nick Coghlan37ee8502010-12-03 14:26:13 +0000977- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +0000980- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
981 with a non-empty format string. This is an effort to future-proof user
982 code. If a derived class does not currently implement __format__ but later
983 adds its own __format__, it would most likely break user code that had
984 supplied a format string. This will be changed to a DeprecationWaring in
985 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +0000987- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

989 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
990
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +0000991- Issue #9210: Configure option --with-wctype-functions was removed. Using the
992 functions from the libc caused the methods .upper() and lower() to become
993 locale aware and created subtly wrong results.
994
Georg Brandl27a28582010-10-10 09:49:21 +0000995- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
996 non-ASCII byte in the format string.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +0000998- Issue #4617: Previously it was illegal to delete a name from the local
999 namespace if it occurs as a free variable in a nested block. This limitation
1000 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1001
Georg Brandl27a28582010-10-10 09:49:21 +00001002- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1003 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1004 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1005 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001007- Issue #9757: memoryview objects get a release() method to release the
1008 underlying buffer (previously this was only done when deallocating the
1009 memoryview), and gain support for the context management protocol.
1010
Antoine Pitrou079ce542010-09-08 12:37:10 +00001011- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
1012 thread-local storage key.

Éric Araujoef777bd2010-10-05 00:04:20 +00001040- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001041 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001042 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001043 replacement for old handle_accept() and avoids the user to call accept()

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00001067- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00001068 retry the select() loop instead of bailing out. This is because select() can
1069 incorrectly report a socket as ready for reading (for example, if it received
1070 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00001150- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00001151 it possible for the user to create self-referencing ordered dictionaries which
1152 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001153 approach of using weakref proxies so that reference cycles never get created
1154 in the first place.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00001179- Issue #6394: os.getppid() is now supported on Windows. Note that it will
1180 still return the id of the parent process after it has exited. This process
1181 id may even have been reused by another unrelated process.

Georg Brandl27a28582010-10-10 09:49:21 +00001197 * Update the seed() method to use all of the bits in a string instead of just
1198 the hash value. This makes better use of the seed value and assures the
1199 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00001200
Georg Brandl27a28582010-10-10 09:49:21 +00001201 * Improved the random()-->integer algorithm used in choice(), shuffle(),
1202 sample(), randrange(), and randint(). Formerly, it used int(n*random())
1203 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00001204
1205 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00001224- hashlib has two new constant attributes: algorithms_guaranteed and

1226 guaranteed to exist in all Python implementations and the names of hash
1227 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00001319- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
1320 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
1321 bytecode is a bit simplified. Patch by Demur Rumed.
Antoine Pitrou74a69fa2010-09-04 18:43:52 +00001322
Brett Cannonef0e6c32010-09-04 18:24:04 +00001323- Issue #9766: Rename poorly named variables exposed by _warnings to prevent

Antoine Pitroue0793ba2010-09-01 21:14:16 +00001331
Georg Brandl649971e2010-09-05 17:06:50 +00001332- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
1333 now removed, since their effect was inexistent in 3.x (the default encoding is
1334 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00001335
Antoine Pitroub0fa8312010-09-01 15:10:12 +00001336- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
1337 properly. Patch by Stefan Behnel.
1338
Georg Brandl649971e2010-09-05 17:06:50 +00001339- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
1340 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00001341
Benjamin Peterson33856de2010-08-30 14:41:20 +00001342- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
1343
Benjamin Peterson0e102062010-08-25 23:13:17 +00001344- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.

1356 return characters from the full Unicode range, even on narrow unicode builds
1357 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
1358 in Python is that unicodedata.numeric() now returns the correct value for
1359 large code points, and repr() may consider more characters as printable.
1360
Victor Stinner6c00c142010-08-17 23:37:11 +00001361- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
1362 as a unicode object, instead of a byte string. Function needed to support
1363 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
1364 function.
1365
Victor Stinner6961bd62010-08-17 22:26:51 +00001366- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

1376
Victor Stinner47fcb5b2010-08-13 23:59:58 +00001377- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00001378 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
1379 objects are output as-is.

Antoine Pitrou042b1282010-08-13 21:15:58 +00001384
Georg Brandl649971e2010-09-05 17:06:50 +00001385- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
1386 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00001387

1394 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00001395
Georg Brandl649971e2010-09-05 17:06:50 +00001396- Issue #9416: Fix some issues with complex formatting where the output with no
1397 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00001398
1399 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
1400 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

1783 TypeError instead of giving a DeprecationWarning when a float is parsed using
1784 the 'L' code (for long long). (All other integer codes already raise
1785 TypeError in this case.)

1812 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00001813 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
1814 (2) The comparison raised an OverflowError for large integers, leading to
1815 unpredictable exceptions when combining integers and complex objects in sets

2146 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
2147 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00002148 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00002251- The default size of the re module's compiled regular expression cache has been
2252 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00002253 simply clearing the entire cache on overflow to forgetting the least recently
2254 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00002255 applications that use a lot of regular expressions and limits the impact of
2256 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00002510- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2511 operation raises multiple signals and more than one of those signals is
2512 trapped, the specification determines the order in which the signals should be

2689 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2690 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003160- Issue #6595: The Decimal constructor now allows arbitrary Unicode decimal
3161 digits in input, as recommended by the standard. Previously it was restricted
3162 to accepting [0-9].

Brett Cannon69194272009-07-20 04:23:48 +00003171- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00003172 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
3173 PyPycLoader inherit from this class and provide implementations in relation to
3174 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00003175
Brett Cannon64ef00f2009-07-20 03:19:18 +00003176- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
3177 the documentation said it did even though the code in PyLoader relied on the
3178 abstract method required by ResourceLoader.
3179
Georg Brandl62069d32010-07-31 08:56:11 +00003180- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00003228- Issue #9959: Tweak formula used for computing math.log of an integer,
3229 making it marginally more accurate for exact powers of 2.

3232
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00003233- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00003234 compared to other unix systems. In particular, os.getgroups() does not reflect
3235 any changes made using os.setgroups() but basicly always returns the same
3236 information as the id command. os.getgroups() can now return more than 16
3237 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00003262- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
3263 Prior to this change, timezone adjustment in utctimetuple() could produce
3264 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
3265 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00003267- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
3268 directive. When the ``%z`` directive is present in the format string, an
3269 aware ``datetime`` object is returned with ``tzinfo`` bound to a
3270 ``datetime.timezone`` instance constructed from the parsed offset. If both
3271 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
3272 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00003274- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00003275 implementing ``datetime.tzinfo`` interface. Instances of the new class,
3276 ``datetime.timezone``, return fixed name and UTC offset from their
3277 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
3278 returns ``None``. A class attribute, ``utc`` contains an instance
3279 representing the UTC timezone. Original patch by Rafe Kaplan.

3296 with an improved 'binary-split' algorithm that uses fewer multiplications and
3297 allows many of the multiplications to be performed using plain C integer
3298 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
3299 arguments.

3305 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00003306 the result is now always correctly rounded, and is equivalent to ``td /
3307 timedelta(seconds=1)``.

3316 integer format code, struct.pack first attempts to convert the non-integer
3317 using its __index__ method. If that method is non-existent or raises
3318 TypeError it goes on to try the __int__ method, as described below.

Mark Dickinson865e01a2009-05-07 16:37:01 +00003885- Issue #5914: Add new C API function PyOS_string_to_double, and
3886 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
3887
Eric Smith741191f2009-05-06 13:08:15 +00003888- Issue #3382: float.__format__, complex.__format__, and %-formatting
3889 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

3895
Eric Smith63376222009-05-05 14:04:18 +00003896- Issue #5920: For float.__format__, change the behavior with the
3897 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
3898 to be like 'g' but with at least one decimal point and with a
3899 default precision of 12. Previously, the behavior the same but with
3900 a default precision of 6. This more closely matches str(), and
3901 reduces surprises when adding alignment flags to the empty
3902 presentation type. This also affects the new complex.__format__ in
3903 the same way.
3904
Martin v. Löwis011e8422009-05-05 04:43:17 +00003905- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00003916- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
3917 received a new method, detach(). detach() disconnects the underlying stream
3918 from the buffer or text IO and returns it.
3919
Mark Dickinson33841c32009-05-01 15:37:04 +00003920- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
3921 floats with absolute value over 1e50. Also remove length
3922 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
3923 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00003925- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00003926 format(complex(1, 2./3), '.5') now produces a sensible result.
3927

3930
Eric Smith6dc46f52009-04-27 20:39:49 +00003931- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

3943
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00003944- Issue #3166: Make int -> float conversions correctly rounded.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00003946- Issue #1869 (and many duplicates): make round(x, n) correctly
3947 rounded for a float x, by using the decimal <-> binary conversions
3948 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
3949 consistently agrees with format(x, '.2f').
3950
Benjamin Petersonae937c02009-04-18 20:54:08 +00003951- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

3953
Eric Smith0923d1d2009-04-16 20:16:10 +00003954- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
3955
Eric Smith35e84722009-04-16 20:21:28 +00003956- Issue #5515: str.format() type 'n' combined with commas and leading
3957 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00003958
3959- Implement PEP 378, Format Specifier for Thousands Separator, for
3960 floats.
3961
Mark Dickinson3370cce2009-04-17 22:40:53 +00003962- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003963 1e11, not 1e12. This avoids printing 13 significant digits in
3964 situations where only 12 of them are correct. Example problem
3965 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
3966 long time.)
3967
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003968- Issue #1580: On most platforms, use a 'short' float repr: for a
3969 finite float x, repr(x) now outputs a string based on the shortest
3970 sequence of decimal digits that rounds to x. Previous behaviour was
3971 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00003972 Another minor difference is that the new repr switches to
3973 exponential notation at 1e16 instead of the previous 1e17; this
3974 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003975
3976 There's a new sys attribute sys.float_repr_style, which takes
3977 the value 'short' to indicate that we're using short float repr,
3978 and 'legacy' if the short float repr isn't available for one
3979 reason or another.
3980
3981 The float repr change involves incorporating David Gay's 'perfect
3982 rounding' code into the Python core (it's in Python/dtoa.c). As a
3983 secondary consequence, all string-to-float and float-to-string
3984 conversions (including all float formatting operations) will be
3985 correctly rounded on these platforms.
3986
Georg Brandl5f90d792010-08-01 22:31:05 +00003987 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003988 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00003990- Issue #5759: float() didn't call __float__ on str subclasses.
3991
Georg Brandlabc38772009-04-12 15:51:51 +00003992- The string.maketrans() function is deprecated; there is a new static method
3993 maketrans() on the bytes and bytearray classes. This removes confusion about
3994 the types string.maketrans() is supposed to work with, and mirrors the
3995 methods available on the str class.
3996
R. David Murraydc6da8a2009-04-09 22:16:43 +00003997- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

4164 untrackable objects are not tracked by the garbage collector. This can
4165 reduce the size of collections and therefore the garbage collection overhead
4166 on long-running programs, depending on their particular use of datatypes.

Brett Cannon7f6b4f82009-03-30 21:30:26 +00004221- Issue #5236: Change time.strptime() to only take strings. Didn't work with
4222 bytes already but the failure was non-obvious.
4223
Jesse Noller7af4ef82009-03-30 16:47:15 +00004224- Issue #5177: Multiprocessing's SocketListener class now uses

4235
Lars Gustäbel42e00912009-03-22 20:34:29 +00004236- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
4237 forever on incomplete input. That caused tarfile.open() to hang when used
4238 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
4239 partial bzip2 compressed data.
4240
Mark Dickinson79f52032009-03-17 23:12:51 +00004241- Issue #2110: Add support for thousands separator and 'n' type

4259 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00004260 struct.error instead of returning b'\xff\xff\xff\xff'. The
4261 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
4262 have been removed from the struct module.

4279
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00004280- Issue #5249: time.strftime returned malformed string when format string
4281 contained non ascii character on windows.
4282
Benjamin Petersonf5b52242009-03-02 23:31:26 +00004283- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
4284 source has already been decoded into str.
4285
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00004286- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
4287 rotating the object pointer by 4 bits to the right.
4288
Mark Dickinson87ec0852009-02-09 17:15:59 +00004289- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
4290 it now forces its argument to double before testing for infinity.
4291
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00004292- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
4293 returns a non-number type.
4294
Benjamin Peterson87618552009-02-08 15:00:52 +00004295- Issue #5182: Removed memoryview.__str__.
4296
Mark Dickinsonc008a172009-02-01 13:59:22 +00004297- Issue #1717: Removed builtin cmp() function, dropped tp_compare
4298 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00004299 the type definition cmpfunc. The tp_compare slot has been renamed
4300 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00004301
Georg Brandl1cdd83c2009-04-05 20:24:29 +00004302- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00004303 were suppressing all exceptions. These include list() and bytearray().
4304
Mark Dickinson1124e712009-01-28 21:25:58 +00004305- Issue #4707: round(x, n) now returns an integer if x is an integer.
4306 Previously it returned a float.
4307
Antoine Pitroub52ec782009-01-25 16:34:23 +00004308- Issue #4753: By enabling a configure option named '--with-computed-gotos'
4309 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
4310 evaluation loop is compiled with a new dispatch mechanism which gives
4311 speedups of up to 20%, depending on the system, on various benchmarks.
4312
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00004313- Issue #4874: Most builtin decoders now reject unicode input.

4319
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00004320- Issue #4838: When a module is deallocated, free the memory backing the
4321 optional module state data.
4322
Mark Dickinson8055afd2009-01-17 10:04:45 +00004323- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004324 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00004325
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00004326- Issue #4935: The overflow checking code in the expandtabs() method common
4327 to str, bytes and bytearray could be optimized away by the compiler, letting
4328 the interpreter segfault instead of raising an error.
4329
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00004330- Issue #3720: Fix a crash when an iterator modifies its class and removes its
4331 __next__ method.
4332
Mark Dickinsone5e298f2009-01-12 20:49:19 +00004333- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
4334 function no longer attempt to call the __long__ slot to convert an object
4335 to an integer. Only the __int__ and __trunc__ slots are examined.
4336
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00004337- Issue #4893: Use NT threading on CE.
4338

4340
Antoine Pitrouab868312009-01-10 15:40:25 +00004341- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
4342 common cases are optimized thanks to a dedicated fast path and a moderate
4343 amount of loop unrolling.
4344
Antoine Pitrou14b78f52009-01-09 22:27:08 +00004345- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
4346 collecting the oldest generation) so that allocating lots of objects without
4347 destroying them does not show quadratic performance. Based on a proposal by
4348 Martin von Löwis at
4349 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
4350
Vinay Sajip6268cbc2009-01-21 00:19:28 +00004351- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00004352 having been closed (for instance, a read() call could return some
4353 previously buffered data). Patch by Dmitry Vasiliev.
4354
Antoine Pitrou05608432009-01-09 18:53:14 +00004355- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
4356 flag to work properly. Furthermore, when specifying -u, the text stdout
4357 and stderr streams have line-by-line buffering enabled (the default being
4358 to buffer arbitrary chunks of data).
4359
Raymond Hettinger35631532009-01-09 03:58:09 +00004360- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
4361 instead of ints (reducing its size from 4 to 8 times thereby reducing
4362 Python's overall memory).
4363
Antoine Pitroud35cbf62009-01-06 19:02:24 +00004364- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
4365 an existing .py counterpart, override the co_filename attributes of all
4366 code objects if the original filename is obsolete (which can happen if the
4367 file has been renamed, moved, or if it is accessed through different paths).
4368 Patch by Ziga Seilnacht and Jean-Paul Calderone.
4369
Antoine Pitrouc3b39242009-01-03 16:59:18 +00004370- Issue #4580: Fix slicing of memoryviews when the item size is greater than
4371 one byte. Also fixes the meaning of len() so that it returns the number of
4372 items, rather than the size in bytes.
4373
Martin v. Löwis5c88d812009-01-02 20:47:48 +00004374- Issue #4075: Use OutputDebugStringW in Py_FatalError.
4375
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00004376- Issue #4747: When the terminal does not use utf-8, executing a script with
4377 non-ascii characters in its name could fail with a "SyntaxError: None" error.
4378
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004379- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
4380 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00004381
Antoine Pitrou7ddda782009-01-01 15:35:33 +00004382- Issue #3680: Reference cycles created through a dict, set or deque iterator
4383 did not get collected.
4384
Nick Coghlanf1f2f682008-12-30 07:29:12 +00004385- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
4386 where the tp_hash and tp_dict slots are both NULL.
4387
Georg Brandlccc47b62008-12-28 11:44:14 +00004388- Issue #4759: None is now allowed as the first argument of
4389 bytearray.translate(). It was always allowed for bytes.translate().
4390
Skip Montanaro80072cb2008-12-23 03:51:14 +00004391- Added test case to ensure attempts to read from a file opened for writing
4392 fail.
4393
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00004394- Issue #3106: Speedup some comparisons (str/str and int/int).
4395
Antoine Pitrouf289ae62008-12-18 11:06:25 +00004396- Issue #2183: Simplify and optimize bytecode for list, dict and set
4397 comprehensions. Original patch for list comprehensions by Neal Norwitz.
4398
Antoine Pitrou621601a2008-12-17 23:18:19 +00004399- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
4400 print elapsed times, not only when some objects are uncollectable /
4401 unreachable. Original patch by Neil Schemenauer.
4402
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00004403- Issue #3439: Add a bit_length method to int.
4404
Mark Dickinsonda2706b2008-12-11 18:03:03 +00004405- Issue #2173: When getting device encoding, check that return value of
4406 nl_langinfo is not the empty string. This was causing silent build
4407 failures on OS X.
4408
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00004409- Issue #4597: Fixed several opcodes that weren't always propagating
4410 exceptions.
4411
4412- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00004413 context manager returns a value that cannot be converted to a bool.
4414
Mark Dickinsonfd24b322008-12-06 15:33:31 +00004415- Issue #4445: Replace "sizeof(PyBytesObject)" with
4416 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
4417 bytes instances. On a typical machine this saves 3 bytes of memory
4418 (on average) per allocation of a bytes instance.
4419
Christian Heimesa872de52008-12-05 08:26:55 +00004420- Issue #4533: File read operation was dreadfully slow due to a slowly
4421 growing read buffer. Fixed by using the same growth rate algorithm as
4422 Python 2.x.
4423
Antoine Pitrou5504e892008-12-06 21:27:53 +00004424- Issue #4509: Various issues surrounding resize of bytearray objects to
4425 which there are buffer exports (e.g. memoryview instances).
4426
Georg Brandlf9734072008-12-07 15:30:06 +00004427- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
4428 method on file objects with closefd=False. The file descriptor is still
4429 kept open but the file object behaves like a closed file. The ``FileIO``
4430 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00004431
Antoine Pitroubc420402008-12-07 20:14:49 +00004432- Issue #4569: Interpreter crash when mutating a memoryview with an item size
4433 larger than 1.

4438
Walter Dörwaldc1651a02009-05-03 22:55:55 +00004439- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
4440 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4441 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4442 of using the replace error handler in PyUnicode_DecodeUTF8().
