190 empty.
191
R. David Murray74b89242009-05-13 17:33:03 +0000192- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

240Core and Builtins
241-----------------
242
Mark Dickinson865e01a2009-05-07 16:37:01 +0000243- Issue #5914: Add new C API function PyOS_string_to_double, and
244 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
245
Eric Smith741191f2009-05-06 13:08:15 +0000246- Issue #3382: float.__format__, complex.__format__, and %-formatting
247 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
248 affects nan -> NAN and inf -> INF.
249
Mark Hammond5a607a32009-05-06 08:04:54 +0000250- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
251 in all operations, including splitdrive, split, etc. splitunc() now issues
252 a PendingDeprecation warning.
253
Eric Smith63376222009-05-05 14:04:18 +0000254- Issue #5920: For float.__format__, change the behavior with the
255 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
256 to be like 'g' but with at least one decimal point and with a
257 default precision of 12. Previously, the behavior the same but with
258 a default precision of 6. This more closely matches str(), and
259 reduces surprises when adding alignment flags to the empty
260 presentation type. This also affects the new complex.__format__ in
261 the same way.
262
Martin v. Löwis011e8422009-05-05 04:43:17 +0000263- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

271
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000272- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000273
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000274- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
275 received a new method, detach(). detach() disconnects the underlying stream
276 from the buffer or text IO and returns it.
277
Mark Dickinson33841c32009-05-01 15:37:04 +0000278- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
279 floats with absolute value over 1e50. Also remove length
280 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
281 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000282

287 never gives more than the requested number of significant digits.
288
Eric Smith6dc46f52009-04-27 20:39:49 +0000289- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
290 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
291

Mark Dickinsone6a076d2009-04-18 11:48:33 +0000304- Issue #1869 (and many duplicates): make round(x, n) correctly
305 rounded for a float x, by using the decimal <-> binary conversions
306 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
307 consistently agrees with format(x, '.2f').
308
Benjamin Petersonae937c02009-04-18 20:54:08 +0000309- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

315 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000316
317- Implement PEP 378, Format Specifier for Thousands Separator, for
318 floats.
319
Mark Dickinson3370cce2009-04-17 22:40:53 +0000320- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000321 1e11, not 1e12. This avoids printing 13 significant digits in
322 situations where only 12 of them are correct. Example problem
323 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
324 long time.)
325
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000326- Issue #1580: On most platforms, use a 'short' float repr: for a
327 finite float x, repr(x) now outputs a string based on the shortest
328 sequence of decimal digits that rounds to x. Previous behaviour was
329 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000330 Another minor difference is that the new repr switches to
331 exponential notation at 1e16 instead of the previous 1e17; this
332 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000333
334 There's a new sys attribute sys.float_repr_style, which takes
335 the value 'short' to indicate that we're using short float repr,
336 and 'legacy' if the short float repr isn't available for one
337 reason or another.
338
339 The float repr change involves incorporating David Gay's 'perfect
340 rounding' code into the Python core (it's in Python/dtoa.c). As a
341 secondary consequence, all string-to-float and float-to-string
342 conversions (including all float formatting operations) will be
343 correctly rounded on these platforms.
344
345 See issue 1580 discussions for details of platforms for which
346 this change does not apply.
347
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000348- Issue #5759: float() didn't call __float__ on str subclasses.
349
Georg Brandlabc38772009-04-12 15:51:51 +0000350- The string.maketrans() function is deprecated; there is a new static method
351 maketrans() on the bytes and bytearray classes. This removes confusion about
352 the types string.maketrans() is supposed to work with, and mirrors the
353 methods available on the str class.
354
R. David Murraydc6da8a2009-04-09 22:16:43 +0000355- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Mark Dickinson1124e712009-01-28 21:25:58 +0000661- Issue #4707: round(x, n) now returns an integer if x is an integer.
662 Previously it returned a float.
663
Antoine Pitroub52ec782009-01-25 16:34:23 +0000664- Issue #4753: By enabling a configure option named '--with-computed-gotos'
665 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
666 evaluation loop is compiled with a new dispatch mechanism which gives
667 speedups of up to 20%, depending on the system, on various benchmarks.

681
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000682- Issue #4935: The overflow checking code in the expandtabs() method common
683 to str, bytes and bytearray could be optimized away by the compiler, letting
684 the interpreter segfault instead of raising an error.
685
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000686- Issue #3720: Fix a crash when an iterator modifies its class and removes its

698 common cases are optimized thanks to a dedicated fast path and a moderate
699 amount of loop unrolling.
700
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000701- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
702 collecting the oldest generation) so that allocating lots of objects without
703 destroying them does not show quadratic performance. Based on a proposal by
704 Martin von Löwis at
705 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
706
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000707- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000708 having been closed (for instance, a read() call could return some
709 previously buffered data). Patch by Dmitry Vasiliev.
710
Antoine Pitrou05608432009-01-09 18:53:14 +0000711- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
712 flag to work properly. Furthermore, when specifying -u, the text stdout
713 and stderr streams have line-by-line buffering enabled (the default being
714 to buffer arbitrary chunks of data).
715
Raymond Hettinger35631532009-01-09 03:58:09 +0000716- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
717 instead of ints (reducing its size from 4 to 8 times thereby reducing
718 Python's overall memory).
719
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000720- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
721 an existing .py counterpart, override the co_filename attributes of all
722 code objects if the original filename is obsolete (which can happen if the
723 file has been renamed, moved, or if it is accessed through different paths).
724 Patch by Ziga Seilnacht and Jean-Paul Calderone.
725
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000726- Issue #4580: Fix slicing of memoryviews when the item size is greater than
727 one byte. Also fixes the meaning of len() so that it returns the number of
728 items, rather than the size in bytes.
729
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000730- Issue #4075: Use OutputDebugStringW in Py_FatalError.

763 failures on OS X.
764
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000765- Issue #4597: Fixed several opcodes that weren't always propagating

767
768- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000769 context manager returns a value that cannot be converted to a bool.
770
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000771- Issue #4445: Replace "sizeof(PyBytesObject)" with
772 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
773 bytes instances. On a typical machine this saves 3 bytes of memory
774 (on average) per allocation of a bytes instance.
775
Christian Heimesa872de52008-12-05 08:26:55 +0000776- Issue #4533: File read operation was dreadfully slow due to a slowly
777 growing read buffer. Fixed by using the same growth rate algorithm as
778 Python 2.x.
779
Antoine Pitrou5504e892008-12-06 21:27:53 +0000780- Issue #4509: Various issues surrounding resize of bytearray objects to
781 which there are buffer exports (e.g. memoryview instances).
782
Georg Brandlf9734072008-12-07 15:30:06 +0000783- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
784 method on file objects with closefd=False. The file descriptor is still
785 kept open but the file object behaves like a closed file. The ``FileIO``
786 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000787
Antoine Pitroubc420402008-12-07 20:14:49 +0000788- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +0000795- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
796 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
797 step. This avoids problems with counting UTF-8 bytes that ignores the effect
798 of using the replace error handler in PyUnicode_DecodeUTF8().
