128 (1) inf and nan strings with trailing whitespace were incorrectly
129 rejected; (2) parsing of strings representing infinities and nans
130 was locale aware; and (3) the interpretation of fromhex('-nan')
131 didn't match that of float('-nan').

151
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000152- Issue #6050: Don't fail extracting a directory from a zipfile if

154
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000155- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
156 than an int, which makes some operations possible under 64-bit Linux (e.g.

Antoine Pitroue4501852009-05-14 18:55:55 +0000181- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
182 library. This means, for example, that opening an UTF-16 text file in
183 append mode doesn't add a BOM at the end of the file if the file isn't
184 empty.
185
R. David Murray74b89242009-05-13 17:33:03 +0000186- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
187 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
188 corrects a pydoc regression.
189
R. David Murray99352742009-05-07 18:24:38 +0000190- Issue 5955: aifc's close method did not close the file it wrapped,
191 now it does. This also means getfp method now returns the real fp.

222
223- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
224 tests on darwin even when the OS was installed on a case-sensitive

234Core and Builtins
235-----------------
236
Mark Dickinson865e01a2009-05-07 16:37:01 +0000237- Issue #5914: Add new C API function PyOS_string_to_double, and
238 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
239
Eric Smith741191f2009-05-06 13:08:15 +0000240- Issue #3382: float.__format__, complex.__format__, and %-formatting
241 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
242 affects nan -> NAN and inf -> INF.
243
Mark Hammond5a607a32009-05-06 08:04:54 +0000244- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
245 in all operations, including splitdrive, split, etc. splitunc() now issues
246 a PendingDeprecation warning.
247
Eric Smith63376222009-05-05 14:04:18 +0000248- Issue #5920: For float.__format__, change the behavior with the
249 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
250 to be like 'g' but with at least one decimal point and with a
251 default precision of 12. Previously, the behavior the same but with
252 a default precision of 6. This more closely matches str(), and
253 reduces surprises when adding alignment flags to the empty
254 presentation type. This also affects the new complex.__format__ in
255 the same way.
256
Martin v. Löwis011e8422009-05-05 04:43:17 +0000257- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
258
R. David Murrayb18500d2009-05-04 22:59:07 +0000259- Issue #5890: in subclasses of 'property' the __doc__ attribute was
260 shadowed by classtype's, even if it was None. property now
261 inserts the __doc__ into the subclass instance __dict__.
262
Antoine Pitrou244651a2009-05-04 18:56:13 +0000263- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
264 sequences. Patch by Nick Barnes and Victor Stinner.
265
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000266- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000267
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000268- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
269 received a new method, detach(). detach() disconnects the underlying stream
270 from the buffer or text IO and returns it.
271
Mark Dickinson33841c32009-05-01 15:37:04 +0000272- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
273 floats with absolute value over 1e50. Also remove length
274 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
275 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000276
Eric Smith741191f2009-05-06 13:08:15 +0000277- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000278 format(complex(1, 2./3), '.5') now produces a sensible result.
279
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000280- Issue #5864: Fix empty format code formatting for floats so that it
281 never gives more than the requested number of significant digits.
282
Eric Smith6dc46f52009-04-27 20:39:49 +0000283- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
284 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
285
Eric Smithcc32a112009-04-26 21:35:14 +0000286- Issue #5835: Deprecate PyOS_ascii_formatd.
287

289 titlecase, but not their own uppercase.
290
Benjamin Peterson193152c2009-04-25 01:08:45 +0000291- Issue #5283: Setting __class__ in __del__ caused a segfault.
292
Mark Dickinsonad476da2009-04-23 19:14:16 +0000293- Issue #5816: complex(repr(z)) now recovers z exactly, even when
294 z involves nans, infs or negative zeros.
295
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000296- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000297
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000298- Issue #1869 (and many duplicates): make round(x, n) correctly
299 rounded for a float x, by using the decimal <-> binary conversions
300 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
301 consistently agrees with format(x, '.2f').
302
Benjamin Petersonae937c02009-04-18 20:54:08 +0000303- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
304 some builtin types.
305
Eric Smith0923d1d2009-04-16 20:16:10 +0000306- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
307
Eric Smith35e84722009-04-16 20:21:28 +0000308- Issue #5515: str.format() type 'n' combined with commas and leading
309 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000310
311- Implement PEP 378, Format Specifier for Thousands Separator, for
312 floats.
313
Mark Dickinson3370cce2009-04-17 22:40:53 +0000314- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000315 1e11, not 1e12. This avoids printing 13 significant digits in
316 situations where only 12 of them are correct. Example problem
317 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
318 long time.)
319
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000320- Issue #1580: On most platforms, use a 'short' float repr: for a
321 finite float x, repr(x) now outputs a string based on the shortest
322 sequence of decimal digits that rounds to x. Previous behaviour was
323 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000324 Another minor difference is that the new repr switches to
325 exponential notation at 1e16 instead of the previous 1e17; this
326 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000327
328 There's a new sys attribute sys.float_repr_style, which takes
329 the value 'short' to indicate that we're using short float repr,
330 and 'legacy' if the short float repr isn't available for one
331 reason or another.
332
333 The float repr change involves incorporating David Gay's 'perfect
334 rounding' code into the Python core (it's in Python/dtoa.c). As a
335 secondary consequence, all string-to-float and float-to-string
336 conversions (including all float formatting operations) will be
337 correctly rounded on these platforms.
338
339 See issue 1580 discussions for details of platforms for which
340 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000342- Issue #5759: float() didn't call __float__ on str subclasses.
343
Georg Brandlabc38772009-04-12 15:51:51 +0000344- The string.maketrans() function is deprecated; there is a new static method
345 maketrans() on the bytes and bytearray classes. This removes confusion about
346 the types string.maketrans() is supposed to work with, and mirrors the
347 methods available on the str class.

Mark Dickinson1124e712009-01-28 21:25:58 +0000655- Issue #4707: round(x, n) now returns an integer if x is an integer.
656 Previously it returned a float.
657
Antoine Pitroub52ec782009-01-25 16:34:23 +0000658- Issue #4753: By enabling a configure option named '--with-computed-gotos'
659 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
660 evaluation loop is compiled with a new dispatch mechanism which gives
661 speedups of up to 20%, depending on the system, on various benchmarks.

675
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000676- Issue #4935: The overflow checking code in the expandtabs() method common
677 to str, bytes and bytearray could be optimized away by the compiler, letting
678 the interpreter segfault instead of raising an error.
679
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000680- Issue #3720: Fix a crash when an iterator modifies its class and removes its

692 common cases are optimized thanks to a dedicated fast path and a moderate
693 amount of loop unrolling.
694
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000695- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
696 collecting the oldest generation) so that allocating lots of objects without
697 destroying them does not show quadratic performance. Based on a proposal by
698 Martin von Löwis at
699 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

Vinay Sajip6268cbc2009-01-21 00:19:28 +0000701- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000702 having been closed (for instance, a read() call could return some
703 previously buffered data). Patch by Dmitry Vasiliev.
704
Antoine Pitrou05608432009-01-09 18:53:14 +0000705- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
706 flag to work properly. Furthermore, when specifying -u, the text stdout
707 and stderr streams have line-by-line buffering enabled (the default being
708 to buffer arbitrary chunks of data).
709
Raymond Hettinger35631532009-01-09 03:58:09 +0000710- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
711 instead of ints (reducing its size from 4 to 8 times thereby reducing
712 Python's overall memory).
713
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000714- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
715 an existing .py counterpart, override the co_filename attributes of all
716 code objects if the original filename is obsolete (which can happen if the
717 file has been renamed, moved, or if it is accessed through different paths).
718 Patch by Ziga Seilnacht and Jean-Paul Calderone.
719
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000720- Issue #4580: Fix slicing of memoryviews when the item size is greater than

722 items, rather than the size in bytes.
723

764
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000765- Issue #4445: Replace "sizeof(PyBytesObject)" with
766 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
767 bytes instances. On a typical machine this saves 3 bytes of memory
768 (on average) per allocation of a bytes instance.
769
Christian Heimesa872de52008-12-05 08:26:55 +0000770- Issue #4533: File read operation was dreadfully slow due to a slowly
771 growing read buffer. Fixed by using the same growth rate algorithm as
772 Python 2.x.
773
Antoine Pitrou5504e892008-12-06 21:27:53 +0000774- Issue #4509: Various issues surrounding resize of bytearray objects to
775 which there are buffer exports (e.g. memoryview instances).
776
Georg Brandlf9734072008-12-07 15:30:06 +0000777- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
778 method on file objects with closefd=False. The file descriptor is still
779 kept open but the file object behaves like a closed file. The ``FileIO``
780 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000781
Antoine Pitroubc420402008-12-07 20:14:49 +0000782- Issue #4569: Interpreter crash when mutating a memoryview with an item size

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