261
Mark Dickinson865e01a2009-05-07 16:37:01 +0000262- Issue #5914: Add new C API function PyOS_string_to_double, and
263 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
264
Eric Smith741191f2009-05-06 13:08:15 +0000265- Issue #3382: float.__format__, complex.__format__, and %-formatting
266 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
267 affects nan -> NAN and inf -> INF.
268
Mark Hammond5a607a32009-05-06 08:04:54 +0000269- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
270 in all operations, including splitdrive, split, etc. splitunc() now issues

Eric Smith63376222009-05-05 14:04:18 +0000273- Issue #5920: For float.__format__, change the behavior with the
274 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')

276 default precision of 12. Previously, the behavior the same but with
277 a default precision of 6. This more closely matches str(), and
278 reduces surprises when adding alignment flags to the empty
279 presentation type. This also affects the new complex.__format__ in
280 the same way.

294 received a new method, detach(). detach() disconnects the underlying stream
295 from the buffer or text IO and returns it.
296
Mark Dickinson33841c32009-05-01 15:37:04 +0000297- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
298 floats with absolute value over 1e50. Also remove length
299 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000321- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000322
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000323- Issue #1869 (and many duplicates): make round(x, n) correctly
324 rounded for a float x, by using the decimal <-> binary conversions
325 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
326 consistently agrees with format(x, '.2f').
327
Benjamin Petersonae937c02009-04-18 20:54:08 +0000328- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

330
Eric Smith0923d1d2009-04-16 20:16:10 +0000331- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
332
Eric Smith35e84722009-04-16 20:21:28 +0000333- Issue #5515: str.format() type 'n' combined with commas and leading
334 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000335
336- Implement PEP 378, Format Specifier for Thousands Separator, for
337 floats.
338
Mark Dickinson3370cce2009-04-17 22:40:53 +0000339- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000340 1e11, not 1e12. This avoids printing 13 significant digits in
341 situations where only 12 of them are correct. Example problem
342 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
343 long time.)
344
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000345- Issue #1580: On most platforms, use a 'short' float repr: for a
346 finite float x, repr(x) now outputs a string based on the shortest
347 sequence of decimal digits that rounds to x. Previous behaviour was
348 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000349 Another minor difference is that the new repr switches to
350 exponential notation at 1e16 instead of the previous 1e17; this
351 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000352
353 There's a new sys attribute sys.float_repr_style, which takes
354 the value 'short' to indicate that we're using short float repr,
355 and 'legacy' if the short float repr isn't available for one
356 reason or another.
357
358 The float repr change involves incorporating David Gay's 'perfect
359 rounding' code into the Python core (it's in Python/dtoa.c). As a
360 secondary consequence, all string-to-float and float-to-string
361 conversions (including all float formatting operations) will be
362 correctly rounded on these platforms.
363
364 See issue 1580 discussions for details of platforms for which
365 this change does not apply.
366
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000367- Issue #5759: float() didn't call __float__ on str subclasses.
368
Georg Brandlabc38772009-04-12 15:51:51 +0000369- The string.maketrans() function is deprecated; there is a new static method
370 maketrans() on the bytes and bytearray classes. This removes confusion about
371 the types string.maketrans() is supposed to work with, and mirrors the
372 methods available on the str class.
373
R. David Murraydc6da8a2009-04-09 22:16:43 +0000374- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

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

634 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +0000635 struct.error instead of returning b'\xff\xff\xff\xff'. The
636 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
637 have been removed from the struct module.

659 source has already been decoded into str.
660
Antoine Pitrou79eee6b2009-02-13 14:01:05 +0000661- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

663
Mark Dickinson87ec0852009-02-09 17:15:59 +0000664- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000677- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000678 were suppressing all exceptions. These include list() and bytearray().
679
Mark Dickinson1124e712009-01-28 21:25:58 +0000680- Issue #4707: round(x, n) now returns an integer if x is an integer.
681 Previously it returned a float.
682
Antoine Pitroub52ec782009-01-25 16:34:23 +0000683- Issue #4753: By enabling a configure option named '--with-computed-gotos'
684 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
685 evaluation loop is compiled with a new dispatch mechanism which gives
686 speedups of up to 20%, depending on the system, on various benchmarks.
687

692
Benjamin Peterson05e782f2009-01-19 15:15:02 +0000693- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
694
Antoine Pitroue4bc7f62009-01-17 21:06:43 +0000695- Issue #4838: When a module is deallocated, free the memory backing the
696 optional module state data.
697
Mark Dickinson8055afd2009-01-17 10:04:45 +0000698- Issue #4910: Rename nb_long slot to nb_reserved, and change its
699 type to (void *).
700
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000701- Issue #4935: The overflow checking code in the expandtabs() method common
702 to str, bytes and bytearray could be optimized away by the compiler, letting
703 the interpreter segfault instead of raising an error.
704
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000705- Issue #3720: Fix a crash when an iterator modifies its class and removes its
706 __next__ method.
707
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000708- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
709 function no longer attempt to call the __long__ slot to convert an object
710 to an integer. Only the __int__ and __trunc__ slots are examined.
711

715
Antoine Pitrouab868312009-01-10 15:40:25 +0000716- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
717 common cases are optimized thanks to a dedicated fast path and a moderate
718 amount of loop unrolling.
719
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000720- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
721 collecting the oldest generation) so that allocating lots of objects without
722 destroying them does not show quadratic performance. Based on a proposal by
723 Martin von Löwis at
724 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
725
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000726- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000727 having been closed (for instance, a read() call could return some
728 previously buffered data). Patch by Dmitry Vasiliev.
729
Antoine Pitrou05608432009-01-09 18:53:14 +0000730- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
731 flag to work properly. Furthermore, when specifying -u, the text stdout
732 and stderr streams have line-by-line buffering enabled (the default being
733 to buffer arbitrary chunks of data).
734
Raymond Hettinger35631532009-01-09 03:58:09 +0000735- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
736 instead of ints (reducing its size from 4 to 8 times thereby reducing
737 Python's overall memory).
738
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000739- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
740 an existing .py counterpart, override the co_filename attributes of all
741 code objects if the original filename is obsolete (which can happen if the
742 file has been renamed, moved, or if it is accessed through different paths).
743 Patch by Ziga Seilnacht and Jean-Paul Calderone.
744
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000745- Issue #4580: Fix slicing of memoryviews when the item size is greater than
746 one byte. Also fixes the meaning of len() so that it returns the number of
747 items, rather than the size in bytes.
748
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000749- Issue #4075: Use OutputDebugStringW in Py_FatalError.
750
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000751- Issue #4747: When the terminal does not use utf-8, executing a script with
752 non-ascii characters in its name could fail with a "SyntaxError: None" error.
753
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000754- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +0000755 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000756
Antoine Pitrou7ddda782009-01-01 15:35:33 +0000757- Issue #3680: Reference cycles created through a dict, set or deque iterator
758 did not get collected.
759
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000760- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
761 where the tp_hash and tp_dict slots are both NULL.
762
Georg Brandlccc47b62008-12-28 11:44:14 +0000763- Issue #4759: None is now allowed as the first argument of
764 bytearray.translate(). It was always allowed for bytes.translate().
765
Skip Montanaro80072cb2008-12-23 03:51:14 +0000766- Added test case to ensure attempts to read from a file opened for writing
767 fail.
768
Antoine Pitrou51f3ef92008-12-20 13:14:23 +0000769- Issue #3106: Speedup some comparisons (str/str and int/int).
770
Antoine Pitrouf289ae62008-12-18 11:06:25 +0000771- Issue #2183: Simplify and optimize bytecode for list, dict and set
772 comprehensions. Original patch for list comprehensions by Neal Norwitz.
773
Antoine Pitrou621601a2008-12-17 23:18:19 +0000774- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
775 print elapsed times, not only when some objects are uncollectable /
776 unreachable. Original patch by Neil Schemenauer.
777
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000778- Issue #3439: Add a bit_length method to int.
779
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000780- Issue #2173: When getting device encoding, check that return value of
781 nl_langinfo is not the empty string. This was causing silent build
782 failures on OS X.
783
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000784- Issue #4597: Fixed several opcodes that weren't always propagating
785 exceptions.
786
787- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000788 context manager returns a value that cannot be converted to a bool.
789
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000790- Issue #4445: Replace "sizeof(PyBytesObject)" with
791 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
792 bytes instances. On a typical machine this saves 3 bytes of memory
793 (on average) per allocation of a bytes instance.
794
Christian Heimesa872de52008-12-05 08:26:55 +0000795- Issue #4533: File read operation was dreadfully slow due to a slowly
796 growing read buffer. Fixed by using the same growth rate algorithm as
797 Python 2.x.
798
Antoine Pitrou5504e892008-12-06 21:27:53 +0000799- Issue #4509: Various issues surrounding resize of bytearray objects to
800 which there are buffer exports (e.g. memoryview instances).
801
Georg Brandlf9734072008-12-07 15:30:06 +0000802- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
803 method on file objects with closefd=False. The file descriptor is still
804 kept open but the file object behaves like a closed file. The ``FileIO``
805 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000806
Antoine Pitroubc420402008-12-07 20:14:49 +0000807- Issue #4569: Interpreter crash when mutating a memoryview with an item size
808 larger than 1.
809
Benjamin Peterson371ccfb2008-12-27 19:03:36 +0000810- Issue #4748: Lambda generators no longer return a value.
811
Gregory P. Smithccc5ae72009-03-02 05:21:55 +0000812- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
813
Walter Dörwaldc1651a02009-05-03 22:55:55 +0000814- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
815 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
816 step. This avoids problems with counting UTF-8 bytes that ignores the effect
817 of using the replace error handler in PyUnicode_DecodeUTF8().
