29
Mark Dickinsonf673f0c2010-03-13 09:48:39 +000030- Issue #7845: Rich comparison methods on the complex type now return
31 NotImplemented rather than raising a TypeError when comparing with an
32 incompatible type; this allows user-defined classes to implement their own
33 comparisons with complex.
34
Victor Stinner52f6dd72010-03-12 14:45:56 +000035- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
36 (SIGINT). If an error occurs while importing the site module, the error is

38 module.
39
Benjamin Petersonae5f2f42010-03-07 17:10:51 +000040- Issue #7173: Generator finalization could invalidate sys.exc_info().

69 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
70
Mark Dickinsonbc099642010-01-29 17:27:24 +000071- Issue #7788: Fix an interpreter crash produced by deleting a list
72 slice with very large step value.
73
Eric Smithf7bb5782010-01-27 00:44:57 +000074- Issue #7766: Change sys.getwindowsversion() return value to a named
75 tuple and add the additional members returned in an OSVERSIONINFOEX
76 structure. The new members are service_pack_major, service_pack_minor,
77 suite_mask, and product_type.
78
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000079- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
80 could crash in many places because of the PyByteArray_AS_STRING() macro
81 returning NULL. The macro now returns a statically allocated empty
82 string instead.
83
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000084- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
85 where the right hand operand is a set of constants, by turning the set into
86 a frozenset and pre-building it as a constant. The comparison operation
87 is made against the constant instead of building a new set each time it is
88 executed (a similar optimization already existed which turned a list of
89 constants into a pre-built tuple). Patch and additional tests by Dave
90 Malcolm.
91
Antoine Pitrouf2c54842010-01-13 08:07:53 +000092- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
93 methods of bytes, bytearray and unicode objects by using a common
94 implementation based on stringlib's fast search. Patch by Florent Xicluna.
95
Mark Dickinson45b63652010-01-16 18:10:25 +000096- Issue #7632: Fix various str -> float conversion bugs present in 2.7
97 alpha 2, including: (1) a serious 'wrong output' bug that could
98 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
99 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000100 strings corresponding to subnormal values, (3) a memory leak for
101 some values large enough to cause overflow, and (4) a number of
102 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000103
Benjamin Petersonaea44282010-01-04 01:10:28 +0000104- The __complex__ method is now looked up on the class of instances to make it

114 negative zero) in ** operator. The behaviour now conforms to that
115 described in C99 Annex F.
116
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000117- Issue #1811: improve accuracy and cross-platform consistency for
118 true division of integers: the result of a/b is now correctly
119 rounded for ints a and b (at least on IEEE 754 platforms), and in
120 particular does not depend on the internal representation of an int.
121
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000122- Issue #6834: replace the implementation for the 'python' and 'pythonw'
123 executables on OSX.
124
125 These executables now work properly with the arch(1) command:
126 ``arch -ppc python`` will start a universal binary version of python
127 in PPC mode (unlike previous releases).
128
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000129- Issue #7466: segmentation fault when the garbage collector is called

144 implement the relevant rich comparison methods.
145
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000146- Issue #7298: fixes for range and reversed(range(...)). Iteration
147 over range(a, b, c) incorrectly gave an empty iterator when a, b and
148 c fit in C long but the length of the range did not. Also fix
149 several cases where reversed(range(a, b, c)) gave wrong results, and
150 fix a refleak for reversed(range(a, b, c)) with large arguments.
151
Raymond Hettingerfc438512009-11-01 20:55:33 +0000152- Issue #7244: itertools.izip_longest() no longer ignores exceptions

191 and include information from the Unihan.txt file.
192
Mark Dickinson2683ab02009-09-29 19:21:35 +0000193- Issue #7019: Raise ValueError when unmarshalling bad long data, instead
194 of producing internally inconsistent Python longs.
195

264 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
265 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
266 DeprecationWarning for float arguments passed with the 'L' format
267 code. This will become a TypeError in a future version of Python,
268 to match the behaviour of the other integer format codes.
269
Georg Brandl1e28a272009-12-28 08:41:01 +0000270- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

280 should used for accessing the d_type and d_name members of structures
281 using PyDescr_COMMON.
282
283- Issue #6405: Remove duplicate type declarations in descrobject.h.

Mark Dickinsonac256ab2010-04-03 11:08:14 +0000313- Issue #7279: Comparisons involving a Decimal signaling NaN now
314 signal InvalidOperation instead of returning False. (Comparisons
315 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
316 are now hashable; Decimal signaling NaNs remain unhashable.
317
318- Issue #2531: Comparison operations between floats and Decimal
319 instances now return a result based on the numeric values of the
320 operands; previously they returned an arbitrary result based on
321 the relative ordering of id(float) and id(Decimal).
322
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000323- Added a subtract() method to collections.Counter().
324
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000325- Issue #8233: When run as a script, py_compile.py optionally takes a single
326 argument `-` which tells it to read files to compile from stdin. Each line
327 is read on demand and the named file is compiled immediately. (Original
328 patch by Piotr Ożarowski).
329
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000330- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
331 form feed (0x0C) are now considered linebreaks, as specified in Unicode
332 Standard Annex #14. See issue #7643.
333 http://www.unicode.org/reports/tr14/
334
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000335- Comparisons using one of <, <=, >, >= between a complex instance and
336 a Fractions instance now raise TypeError instead of returning
337 True/False. This makes Fraction <=> complex comparisons consistent with
338 int <=> complex, float <=> complex, and complex <=> complex comparisons.
339

352 when Python is running in WOW64 mode on 64 bit Windows.
353
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000354- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
355 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking

379 the locale.
380
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000381- The internals of the subprocess module on POSIX systems have been replaced
382 by an extension module (_posixsubprocess) so that the fork()+exec() can be
383 done safely without the possibility of deadlock in multithreaded applications.
384
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000385- subprocess.Popen now has restore_signals and start_new_session features.
386 The default of restore_signals=True is a new behavior compared to earlier
387 Python versions. This means that signals such as SIGPIPE are not ignored
388 by default in subprocesses launched by Python (Issue #1652).
389
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000390- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

476 file position when calling `truncate()`. It would previously change the
477 file position to the given argument, which goes against the tradition of
478 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +0000480- Issue #7610: Reworked implementation of the internal
481 :class:`zipfile.ZipExtFile` class used to represent files stored inside
482 an archive. The new implementation is significantly faster and can

484 It also solves an issue where interleaved calls to `read()` and
485 `readline()` give wrong results. Patch by Nir Aides.

1060 a test fails. Can be combined with -j.
1061
Antoine Pitrou060cee22009-11-13 16:29:04 +00001062- Issue #6551: test_zipimport could import and then destroy some modules of

1073 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1074 between concurrent executions on the same system.
1075
Brett Cannon0ae45112009-11-05 01:17:22 +00001076- Issue #7248: In importlib.test.source.util a try/finally block did not make
1077 sure that some referenced objects actually were created in the block before
1078 calling methods on the object.
1079
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001080- Issue #7222: Make thread "reaping" more reliable so that reference
1081 leak-chasing test runs give sensible results. The previous method of
1082 reaping threads could return successfully while some Thread objects were
1083 still referenced. This also introduces a new private function:
1084 :func:`_thread._count()`.
1085
R. David Murray27144602009-10-19 15:26:16 +00001086- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1087 longer runs the risk of causing the worker thread to fail.
1088
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001089- Issue #7055: test___all__ now greedily detects all modules which have an
1090 __all__ attribute, rather than using a hardcoded and incomplete list.

1093 runtest_inner in regrtest, with warnings if the called test modifies them,
1094 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001095
Mark Dickinson2e304402009-10-04 18:43:54 +00001096- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1097
Brett Cannon3c273842009-07-20 00:14:29 +00001098- Fixed tests in importlib.test.source.test_abc_loader that were masking
1099 the proper exceptions that should be raised for missing or improper code
1100 object bytecode.
1101
Brett Cannonb49c70c2009-07-15 04:08:33 +00001102- Removed importlib's custom test discovery code and switched to

1247 that would raise SystemError.
1248
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001249- Issue #5982: staticmethod and classmethod now expose the wrapped
1250 function with __func__.
1251
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001252- Added support for multiple context managers in the same with-statement.
1253 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001255- Issue #5829: complex("1e500") no longer raises OverflowError. This
1256 makes it consistent with float("1e500") and interpretation of real
1257 and imaginary literals.
1258
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001259- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001263- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1264 (1) inf and nan strings with trailing whitespace were incorrectly
1265 rejected; (2) parsing of strings representing infinities and nans
1266 was locale aware; and (3) the interpretation of fromhex('-nan')
1267 didn't match that of float('-nan').

1275
R. David Murray1f1b9d32009-05-27 20:56:59 +00001276- Issue #6121: pydoc now ignores leading and trailing spaces in the

1278
Georg Brandlfaf41492009-05-26 18:31:11 +00001279- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1280 arguments for strings with a space in them.
1281
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001282- collections.namedtuple() was not working with the following field
1283 names: cls, self, tuple, itemgetter, and property.
1284
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001285- In unittest, using a skipping decorator on a class is now equivalent to
1286 skipping every test on the class. The ClassTestSuite class has been removed.
1287
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001288- Issue #6050: Don't fail extracting a directory from a zipfile if
1289 the directory already exists.
1290
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001291- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1292 than an int, which makes some operations possible under 64-bit Linux (e.g.
1293 DN_MULTISHOT with F_NOTIFY).
1294
Antoine Pitrou716c4442009-05-23 19:04:03 +00001295- Issue #5761: Add the name of the underlying file to the repr() of various

1303 a process identifier type wider than the standard C integer type.
1304
R. David Murray87e20742009-05-23 01:30:26 +00001305- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1316
Antoine Pitroue4501852009-05-14 18:55:55 +00001317- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1318 library. This means, for example, that opening an UTF-16 text file in
1319 append mode doesn't add a BOM at the end of the file if the file isn't
1320 empty.
1321
R. David Murray74b89242009-05-13 17:33:03 +00001322- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

1324 corrects a pydoc regression.
1325
R. David Murray99352742009-05-07 18:24:38 +00001326- Issue 5955: aifc's close method did not close the file it wrapped,

1370Core and Builtins
1371-----------------
1372
Mark Dickinson865e01a2009-05-07 16:37:01 +00001373- Issue #5914: Add new C API function PyOS_string_to_double, and
1374 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1375
Eric Smith741191f2009-05-06 13:08:15 +00001376- Issue #3382: float.__format__, complex.__format__, and %-formatting
1377 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1378 affects nan -> NAN and inf -> INF.
1379
Mark Hammond5a607a32009-05-06 08:04:54 +00001380- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1381 in all operations, including splitdrive, split, etc. splitunc() now issues
1382 a PendingDeprecation warning.
1383
Eric Smith63376222009-05-05 14:04:18 +00001384- Issue #5920: For float.__format__, change the behavior with the
1385 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1386 to be like 'g' but with at least one decimal point and with a
1387 default precision of 12. Previously, the behavior the same but with
1388 a default precision of 6. This more closely matches str(), and
1389 reduces surprises when adding alignment flags to the empty
1390 presentation type. This also affects the new complex.__format__ in
1391 the same way.
1392
Martin v. Löwis011e8422009-05-05 04:43:17 +00001393- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1394
R. David Murrayb18500d2009-05-04 22:59:07 +00001395- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1396 shadowed by classtype's, even if it was None. property now
1397 inserts the __doc__ into the subclass instance __dict__.
1398
Antoine Pitrou244651a2009-05-04 18:56:13 +00001399- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1400 sequences. Patch by Nick Barnes and Victor Stinner.
1401
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001402- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001403
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001404- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1405 received a new method, detach(). detach() disconnects the underlying stream
1406 from the buffer or text IO and returns it.
1407
Mark Dickinson33841c32009-05-01 15:37:04 +00001408- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1409 floats with absolute value over 1e50. Also remove length
1410 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1411 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001412
Eric Smith741191f2009-05-06 13:08:15 +00001413- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001414 format(complex(1, 2./3), '.5') now produces a sensible result.
1415
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001416- Issue #5864: Fix empty format code formatting for floats so that it
1417 never gives more than the requested number of significant digits.
1418
Eric Smith6dc46f52009-04-27 20:39:49 +00001419- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1420 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1421
Eric Smithcc32a112009-04-26 21:35:14 +00001422- Issue #5835: Deprecate PyOS_ascii_formatd.
1423
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001424- Issue #4971: Fix titlecase for characters that are their own
1425 titlecase, but not their own uppercase.
1426
Benjamin Peterson193152c2009-04-25 01:08:45 +00001427- Issue #5283: Setting __class__ in __del__ caused a segfault.
1428
Mark Dickinsonad476da2009-04-23 19:14:16 +00001429- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1430 z involves nans, infs or negative zeros.
1431
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001432- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001433
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001434- Issue #1869 (and many duplicates): make round(x, n) correctly
1435 rounded for a float x, by using the decimal <-> binary conversions
1436 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1437 consistently agrees with format(x, '.2f').
1438
Benjamin Petersonae937c02009-04-18 20:54:08 +00001439- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1440 some builtin types.
1441
Eric Smith0923d1d2009-04-16 20:16:10 +00001442- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1443
Eric Smith35e84722009-04-16 20:21:28 +00001444- Issue #5515: str.format() type 'n' combined with commas and leading
1445 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001446
1447- Implement PEP 378, Format Specifier for Thousands Separator, for
1448 floats.
1449
Mark Dickinson3370cce2009-04-17 22:40:53 +00001450- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001451 1e11, not 1e12. This avoids printing 13 significant digits in
1452 situations where only 12 of them are correct. Example problem
1453 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1454 long time.)
1455
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001456- Issue #1580: On most platforms, use a 'short' float repr: for a
1457 finite float x, repr(x) now outputs a string based on the shortest
1458 sequence of decimal digits that rounds to x. Previous behaviour was
1459 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001460 Another minor difference is that the new repr switches to
1461 exponential notation at 1e16 instead of the previous 1e17; this
1462 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001463
1464 There's a new sys attribute sys.float_repr_style, which takes
1465 the value 'short' to indicate that we're using short float repr,
1466 and 'legacy' if the short float repr isn't available for one
1467 reason or another.
1468
1469 The float repr change involves incorporating David Gay's 'perfect
1470 rounding' code into the Python core (it's in Python/dtoa.c). As a
1471 secondary consequence, all string-to-float and float-to-string
1472 conversions (including all float formatting operations) will be
1473 correctly rounded on these platforms.
1474
1475 See issue 1580 discussions for details of platforms for which
1476 this change does not apply.
1477
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001478- Issue #5759: float() didn't call __float__ on str subclasses.
1479
Georg Brandlabc38772009-04-12 15:51:51 +00001480- The string.maketrans() function is deprecated; there is a new static method
1481 maketrans() on the bytes and bytearray classes. This removes confusion about
1482 the types string.maketrans() is supposed to work with, and mirrors the
1483 methods available on the str class.
1484
R. David Murraydc6da8a2009-04-09 22:16:43 +00001485- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1486 its clarity and its speed.
1487
Matthias Klose091c7b12009-04-07 13:24:27 +00001488- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1489 to avoid compiler warnings.
1490
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001491- Issue #3739: The unicode-internal encoder now reports the number of characters
1492 consumed like any other encoder (instead of the number of bytes).

Antoine Pitroub52ec782009-01-25 16:34:23 +00001794- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1795 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1796 evaluation loop is compiled with a new dispatch mechanism which gives
1797 speedups of up to 20%, depending on the system, on various benchmarks.
1798
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001799- Issue #4874: Most builtin decoders now reject unicode input.

1805
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001806- Issue #4838: When a module is deallocated, free the memory backing the
1807 optional module state data.
1808
Mark Dickinson8055afd2009-01-17 10:04:45 +00001809- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1810 type to (void *).
1811
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001812- Issue #4935: The overflow checking code in the expandtabs() method common
1813 to str, bytes and bytearray could be optimized away by the compiler, letting
1814 the interpreter segfault instead of raising an error.
1815
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001816- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1817 __next__ method.
1818
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001819- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1820 function no longer attempt to call the __long__ slot to convert an object
1821 to an integer. Only the __int__ and __trunc__ slots are examined.

1826
Antoine Pitrouab868312009-01-10 15:40:25 +00001827- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1828 common cases are optimized thanks to a dedicated fast path and a moderate
1829 amount of loop unrolling.
1830
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001831- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1832 collecting the oldest generation) so that allocating lots of objects without
1833 destroying them does not show quadratic performance. Based on a proposal by
1834 Martin von Löwis at
1835 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1836
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001837- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001838 having been closed (for instance, a read() call could return some
1839 previously buffered data). Patch by Dmitry Vasiliev.
1840
Antoine Pitrou05608432009-01-09 18:53:14 +00001841- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1842 flag to work properly. Furthermore, when specifying -u, the text stdout
1843 and stderr streams have line-by-line buffering enabled (the default being
1844 to buffer arbitrary chunks of data).
1845
Raymond Hettinger35631532009-01-09 03:58:09 +00001846- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1847 instead of ints (reducing its size from 4 to 8 times thereby reducing
1848 Python's overall memory).
1849
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001850- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1851 an existing .py counterpart, override the co_filename attributes of all
1852 code objects if the original filename is obsolete (which can happen if the
1853 file has been renamed, moved, or if it is accessed through different paths).
1854 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1855
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001856- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1857 one byte. Also fixes the meaning of len() so that it returns the number of
1858 items, rather than the size in bytes.
1859
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001860- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1861
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001862- Issue #4747: When the terminal does not use utf-8, executing a script with
1863 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1864
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001865- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1869 did not get collected.
1870
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001871- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1872 where the tp_hash and tp_dict slots are both NULL.
1873
Georg Brandlccc47b62008-12-28 11:44:14 +00001874- Issue #4759: None is now allowed as the first argument of
1875 bytearray.translate(). It was always allowed for bytes.translate().
1876
Skip Montanaro80072cb2008-12-23 03:51:14 +00001877- Added test case to ensure attempts to read from a file opened for writing
1878 fail.

1884
Antoine Pitrou621601a2008-12-17 23:18:19 +00001885- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1887 unreachable. Original patch by Neil Schemenauer.
1888

1890
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001891- Issue #2173: When getting device encoding, check that return value of
1892 nl_langinfo is not the empty string. This was causing silent build
1893 failures on OS X.
1894
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001895- Issue #4597: Fixed several opcodes that weren't always propagating
1896 exceptions.
1897
1898- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001899 context manager returns a value that cannot be converted to a bool.
1900
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001901- Issue #4445: Replace "sizeof(PyBytesObject)" with
1902 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1903 bytes instances. On a typical machine this saves 3 bytes of memory
1904 (on average) per allocation of a bytes instance.
1905
Christian Heimesa872de52008-12-05 08:26:55 +00001906- Issue #4533: File read operation was dreadfully slow due to a slowly
1907 growing read buffer. Fixed by using the same growth rate algorithm as
1908 Python 2.x.
1909
Antoine Pitrou5504e892008-12-06 21:27:53 +00001910- Issue #4509: Various issues surrounding resize of bytearray objects to
1911 which there are buffer exports (e.g. memoryview instances).
1912
Georg Brandlf9734072008-12-07 15:30:06 +00001913- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1914 method on file objects with closefd=False. The file descriptor is still
1915 kept open but the file object behaves like a closed file. The ``FileIO``
1916 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00001918- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1924
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001925- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1926 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1927 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1928 of using the replace error handler in PyUnicode_DecodeUTF8().
