Eric Smith63376222009-05-05 14:04:18 +0000332- Issue #5920: For float.__format__, change the behavior with the
333 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
334 to be like 'g' but with at least one decimal point and with a
335 default precision of 12. Previously, the behavior the same but with
336 a default precision of 6. This more closely matches str(), and
337 reduces surprises when adding alignment flags to the empty
338 presentation type. This also affects the new complex.__format__ in
339 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000352- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
353 received a new method, detach(). detach() disconnects the underlying stream
354 from the buffer or text IO and returns it.
355
Mark Dickinson33841c32009-05-01 15:37:04 +0000356- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
357 floats with absolute value over 1e50. Also remove length
358 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
359 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000360
Eric Smith741191f2009-05-06 13:08:15 +0000361- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000362 format(complex(1, 2./3), '.5') now produces a sensible result.
363
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000364- Issue #5864: Fix empty format code formatting for floats so that it

379
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000380- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000381
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000382- Issue #1869 (and many duplicates): make round(x, n) correctly
383 rounded for a float x, by using the decimal <-> binary conversions
384 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
385 consistently agrees with format(x, '.2f').
386
Benjamin Petersonae937c02009-04-18 20:54:08 +0000387- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

389
Eric Smith0923d1d2009-04-16 20:16:10 +0000390- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
391
Eric Smith35e84722009-04-16 20:21:28 +0000392- Issue #5515: str.format() type 'n' combined with commas and leading
393 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000394
395- Implement PEP 378, Format Specifier for Thousands Separator, for
396 floats.
397
Mark Dickinson3370cce2009-04-17 22:40:53 +0000398- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000399 1e11, not 1e12. This avoids printing 13 significant digits in
400 situations where only 12 of them are correct. Example problem
401 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
402 long time.)
403
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000404- Issue #1580: On most platforms, use a 'short' float repr: for a
405 finite float x, repr(x) now outputs a string based on the shortest
406 sequence of decimal digits that rounds to x. Previous behaviour was
407 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000408 Another minor difference is that the new repr switches to
409 exponential notation at 1e16 instead of the previous 1e17; this
410 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000411
412 There's a new sys attribute sys.float_repr_style, which takes
413 the value 'short' to indicate that we're using short float repr,
414 and 'legacy' if the short float repr isn't available for one
415 reason or another.
416
417 The float repr change involves incorporating David Gay's 'perfect
418 rounding' code into the Python core (it's in Python/dtoa.c). As a
419 secondary consequence, all string-to-float and float-to-string
420 conversions (including all float formatting operations) will be
421 correctly rounded on these platforms.
422
423 See issue 1580 discussions for details of platforms for which
424 this change does not apply.
425
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000426- Issue #5759: float() didn't call __float__ on str subclasses.
427
Georg Brandlabc38772009-04-12 15:51:51 +0000428- The string.maketrans() function is deprecated; there is a new static method
429 maketrans() on the bytes and bytearray classes. This removes confusion about
430 the types string.maketrans() is supposed to work with, and mirrors the
431 methods available on the str class.
432
R. David Murraydc6da8a2009-04-09 22:16:43 +0000433- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Matthias Klose091c7b12009-04-07 13:24:27 +0000436- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
437 to avoid compiler warnings.
438
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000439- Issue #3739: The unicode-internal encoder now reports the number of characters

596
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000597- Issue #4688: Add a heuristic so that tuples and dicts containing only
598 untrackable objects are not tracked by the garbage collector. This can
599 reduce the size of collections and therefore the garbage collection overhead
600 on long-running programs, depending on their particular use of datatypes.

738
Mark Dickinson1124e712009-01-28 21:25:58 +0000739- Issue #4707: round(x, n) now returns an integer if x is an integer.
740 Previously it returned a float.
741
Antoine Pitroub52ec782009-01-25 16:34:23 +0000742- Issue #4753: By enabling a configure option named '--with-computed-gotos'
743 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
744 evaluation loop is compiled with a new dispatch mechanism which gives
745 speedups of up to 20%, depending on the system, on various benchmarks.

758 type to (void *).
759
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000760- Issue #4935: The overflow checking code in the expandtabs() method common
761 to str, bytes and bytearray could be optimized away by the compiler, letting
762 the interpreter segfault instead of raising an error.
763
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000764- Issue #3720: Fix a crash when an iterator modifies its class and removes its
765 __next__ method.
766
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000767- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
768 function no longer attempt to call the __long__ slot to convert an object
769 to an integer. Only the __int__ and __trunc__ slots are examined.
770

774
Antoine Pitrouab868312009-01-10 15:40:25 +0000775- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
776 common cases are optimized thanks to a dedicated fast path and a moderate
777 amount of loop unrolling.
778
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000779- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
780 collecting the oldest generation) so that allocating lots of objects without
781 destroying them does not show quadratic performance. Based on a proposal by
782 Martin von Löwis at
783 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
784
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000785- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000786 having been closed (for instance, a read() call could return some
787 previously buffered data). Patch by Dmitry Vasiliev.
788
Antoine Pitrou05608432009-01-09 18:53:14 +0000789- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
790 flag to work properly. Furthermore, when specifying -u, the text stdout
791 and stderr streams have line-by-line buffering enabled (the default being
792 to buffer arbitrary chunks of data).
793
Raymond Hettinger35631532009-01-09 03:58:09 +0000794- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
795 instead of ints (reducing its size from 4 to 8 times thereby reducing
796 Python's overall memory).
797
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000798- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
799 an existing .py counterpart, override the co_filename attributes of all
800 code objects if the original filename is obsolete (which can happen if the
801 file has been renamed, moved, or if it is accessed through different paths).
802 Patch by Ziga Seilnacht and Jean-Paul Calderone.
803
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000804- Issue #4580: Fix slicing of memoryviews when the item size is greater than
805 one byte. Also fixes the meaning of len() so that it returns the number of
806 items, rather than the size in bytes.
807
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000808- Issue #4075: Use OutputDebugStringW in Py_FatalError.
809
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000810- Issue #4747: When the terminal does not use utf-8, executing a script with
811 non-ascii characters in its name could fail with a "SyntaxError: None" error.
812
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000813- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

817 did not get collected.
818
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000819- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
820 where the tp_hash and tp_dict slots are both NULL.
821
Georg Brandlccc47b62008-12-28 11:44:14 +0000822- Issue #4759: None is now allowed as the first argument of
823 bytearray.translate(). It was always allowed for bytes.translate().
824
Skip Montanaro80072cb2008-12-23 03:51:14 +0000825- Added test case to ensure attempts to read from a file opened for writing
826 fail.
827

832
Antoine Pitrou621601a2008-12-17 23:18:19 +0000833- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
834 print elapsed times, not only when some objects are uncollectable /
835 unreachable. Original patch by Neil Schemenauer.
836
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000837- Issue #3439: Add a bit_length method to int.
838
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000839- Issue #2173: When getting device encoding, check that return value of
840 nl_langinfo is not the empty string. This was causing silent build
841 failures on OS X.
842
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000843- Issue #4597: Fixed several opcodes that weren't always propagating
844 exceptions.
845
846- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000847 context manager returns a value that cannot be converted to a bool.
848
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000849- Issue #4445: Replace "sizeof(PyBytesObject)" with
850 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
851 bytes instances. On a typical machine this saves 3 bytes of memory
852 (on average) per allocation of a bytes instance.
853
Christian Heimesa872de52008-12-05 08:26:55 +0000854- Issue #4533: File read operation was dreadfully slow due to a slowly
855 growing read buffer. Fixed by using the same growth rate algorithm as
856 Python 2.x.
857
Antoine Pitrou5504e892008-12-06 21:27:53 +0000858- Issue #4509: Various issues surrounding resize of bytearray objects to
859 which there are buffer exports (e.g. memoryview instances).
860
Georg Brandlf9734072008-12-07 15:30:06 +0000861- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
862 method on file objects with closefd=False. The file descriptor is still
863 kept open but the file object behaves like a closed file. The ``FileIO``
864 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000865
Antoine Pitroubc420402008-12-07 20:14:49 +0000866- Issue #4569: Interpreter crash when mutating a memoryview with an item size
867 larger than 1.

874 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
875 step. This avoids problems with counting UTF-8 bytes that ignores the effect
876 of using the replace error handler in PyUnicode_DecodeUTF8().
