13-----------------
14
Victor Stinner808fc0a2010-03-22 12:50:40 +000015- Issue #1583863: An str subclass can now override the __str__ method
16
Mark Dickinsond59b4162010-03-13 11:34:40 +000017- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
18 PyMemberDefs could produce an internal error; raise TypeError instead.
19
Mark Dickinsonf673f0c2010-03-13 09:48:39 +000020- Issue #7845: Rich comparison methods on the complex type now return
21 NotImplemented rather than raising a TypeError when comparing with an
22 incompatible type; this allows user-defined classes to implement their own
23 comparisons with complex.
24
Victor Stinner52f6dd72010-03-12 14:45:56 +000025- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
26 (SIGINT). If an error occurs while importing the site module, the error is
27 printed and Python exits. Initialize the GIL before importing the site
28 module.
29
Benjamin Petersonae5f2f42010-03-07 17:10:51 +000030- Issue #7173: Generator finalization could invalidate sys.exc_info().

33 a fatal error in low memory condition.
34
Victor Stinner6aa278e2010-03-03 00:18:49 +000035- Issue #7820: The parser tokenizer restores all bytes in the right if
36 the BOM check fails.
37
Benjamin Peterson23e018a2010-02-27 17:40:01 +000038- Handle errors from looking up __prepare__ correctly.
39
Larry Hastings1373a072010-02-24 22:49:58 +000040- Issue #5939: Add additional runtime checking to ensure a valid capsule
41 in Modules/_ctypes/callproc.c.
42
Eric Smith0facd772010-02-24 15:42:29 +000043- Issue #7309: Fix unchecked attribute access when converting
44 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
45 strings.
46
Eric Smithabb28c62010-02-23 00:22:24 +000047- Issue #6902: Fix problem with built-in types format incorrectly with
48 0 padding.
49
Eric Smith4e260c52010-02-22 18:54:44 +000050- Issue #7988: Fix default alignment to be right aligned for
51 complex.__format__. Now it matches other numeric types.
52
Eric Smith68af50b2010-02-22 14:58:30 +000053- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
54 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
55 and PyOS_string_to_double instead. See issue #5835 for the original
56 deprecations.
57
Antoine Pitrou05b7c562010-02-02 22:47:00 +000058- Issue #7385: Fix a crash in `MemoryView_FromObject` when
59 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
60
Mark Dickinsonbc099642010-01-29 17:27:24 +000061- Issue #7788: Fix an interpreter crash produced by deleting a list
62 slice with very large step value.
63
Eric Smithf7bb5782010-01-27 00:44:57 +000064- Issue #7766: Change sys.getwindowsversion() return value to a named
65 tuple and add the additional members returned in an OSVERSIONINFOEX
66 structure. The new members are service_pack_major, service_pack_minor,
67 suite_mask, and product_type.
68
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000069- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
70 could crash in many places because of the PyByteArray_AS_STRING() macro
71 returning NULL. The macro now returns a statically allocated empty
72 string instead.
73
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000074- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
75 where the right hand operand is a set of constants, by turning the set into
76 a frozenset and pre-building it as a constant. The comparison operation
77 is made against the constant instead of building a new set each time it is
78 executed (a similar optimization already existed which turned a list of
79 constants into a pre-built tuple). Patch and additional tests by Dave
80 Malcolm.
81
Antoine Pitrouf2c54842010-01-13 08:07:53 +000082- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
83 methods of bytes, bytearray and unicode objects by using a common
84 implementation based on stringlib's fast search. Patch by Florent Xicluna.
85
Mark Dickinson45b63652010-01-16 18:10:25 +000086- Issue #7632: Fix various str -> float conversion bugs present in 2.7
87 alpha 2, including: (1) a serious 'wrong output' bug that could
88 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
89 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000090 strings corresponding to subnormal values, (3) a memory leak for
91 some values large enough to cause overflow, and (4) a number of
92 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000093
Benjamin Petersonaea44282010-01-04 01:10:28 +000094- The __complex__ method is now looked up on the class of instances to make it
95 consistent with other special methods.
96

98 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
99
Benjamin Petersond12362a2009-12-30 19:44:54 +0000100- Issue #7604: Deleting an unset slotted attribute did not raise an
101 AttributeError.
102
Mark Dickinson9ab44b52009-12-30 16:22:49 +0000103- Issue #7534: Fix handling of IEEE specials (infinities, nans,
104 negative zero) in ** operator. The behaviour now conforms to that
105 described in C99 Annex F.
106
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000107- Issue #1811: improve accuracy and cross-platform consistency for
108 true division of integers: the result of a/b is now correctly
109 rounded for ints a and b (at least on IEEE 754 platforms), and in
110 particular does not depend on the internal representation of an int.
111
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000112- Issue #6834: replace the implementation for the 'python' and 'pythonw'
113 executables on OSX.
114
115 These executables now work properly with the arch(1) command:
116 ``arch -ppc python`` will start a universal binary version of python
117 in PPC mode (unlike previous releases).
118
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000119- Issue #7466: segmentation fault when the garbage collector is called

123 with invalid values.
124
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000125- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
126 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
127
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000128- Issue #7085: Fix crash when importing some extensions in a thread
129 on MacOSX 10.6.

132
Mark Dickinson6f1d0492009-11-15 13:58:49 +0000133- Issue #6970: Remove redundant calls when comparing objects that don't
134 implement the relevant rich comparison methods.
135
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000136- Issue #7298: fixes for range and reversed(range(...)). Iteration
137 over range(a, b, c) incorrectly gave an empty iterator when a, b and
138 c fit in C long but the length of the range did not. Also fix
139 several cases where reversed(range(a, b, c)) gave wrong results, and
140 fix a refleak for reversed(range(a, b, c)) with large arguments.
141
Raymond Hettingerfc438512009-11-01 20:55:33 +0000142- Issue #7244: itertools.izip_longest() no longer ignores exceptions

315 done safely without the possibility of deadlock in multithreaded applications.
316
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000317- subprocess.Popen now has restore_signals and start_new_session features.
318 The default of restore_signals=True is a new behavior compared to earlier
319 Python versions. This means that signals such as SIGPIPE are not ignored
320 by default in subprocesses launched by Python (Issue #1652).

382 exception of canonical and is_canonical) now accept instances of int
383 and long wherever a Decimal instance is accepted, and implicitly

408 file position when calling `truncate()`. It would previously change the
409 file position to the given argument, which goes against the tradition of
410 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
411
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000412- Issue #7610: Reworked implementation of the internal
413 :class:`zipfile.ZipExtFile` class used to represent files stored inside
414 an archive. The new implementation is significantly faster and can
415 be wrapped in a :class:`io.BufferedReader` object for more speedups.
416 It also solves an issue where interleaved calls to `read()` and
417 `readline()` give wrong results. Patch by Nir Aides.
418

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000580- Issue #6816: runpy now provides a run_path function that allows Python code
581 to execute file paths that refer to source or compiled Python files as well
582 as zipfiles, directories and other valid sys.path entries that contain a
583 __main__.py file. This allows applications that run other Python scripts to
584 support the same flexibility as the CPython command line itself.
585
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000586- Issue #7318: multiprocessing now uses a timeout when it fails to establish

976 a test fails. Can be combined with -j.
977
Antoine Pitrou060cee22009-11-13 16:29:04 +0000978- Issue #6551: test_zipimport could import and then destroy some modules of
979 the encodings package, which would make other tests fail further down
980 the road because the internally cached encoders and decoders would point
981 to empty global variables.
982
Antoine Pitrou941ee882009-11-11 20:59:38 +0000983- Issue #7295: Do not use a hardcoded file name in test_tarfile.

989 tests instead of tempfile.tempdir. This prevents the tests from sharing state
990 between concurrent executions on the same system.
991
Brett Cannon0ae45112009-11-05 01:17:22 +0000992- Issue #7248: In importlib.test.source.util a try/finally block did not make
993 sure that some referenced objects actually were created in the block before
994 calling methods on the object.
995
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000996- Issue #7222: Make thread "reaping" more reliable so that reference
997 leak-chasing test runs give sensible results. The previous method of
998 reaping threads could return successfully while some Thread objects were
999 still referenced. This also introduces a new private function:
1000 :func:`_thread._count()`.
1001
R. David Murray27144602009-10-19 15:26:16 +00001002- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1003 longer runs the risk of causing the worker thread to fail.
1004
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001005- Issue #7055: test___all__ now greedily detects all modules which have an
1006 __all__ attribute, rather than using a hardcoded and incomplete list.
1007
R. David Murray0bc11ae2009-10-18 22:18:17 +00001008- Issue #7058: Added save/restore for things like sys.argv and cwd to
1009 runtest_inner in regrtest, with warnings if the called test modifies them,
1010 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001011
Mark Dickinson2e304402009-10-04 18:43:54 +00001012- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1013
Brett Cannon3c273842009-07-20 00:14:29 +00001014- Fixed tests in importlib.test.source.test_abc_loader that were masking
1015 the proper exceptions that should be raised for missing or improper code
1016 object bytecode.
1017
Brett Cannonb49c70c2009-07-15 04:08:33 +00001018- Removed importlib's custom test discovery code and switched to
1019 unittest.TestLoader.discover().

Martin v. Löwis70ccd162009-05-24 19:47:22 +00001204- Issue #6050: Don't fail extracting a directory from a zipfile if
1205 the directory already exists.
1206
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001207- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1208 than an int, which makes some operations possible under 64-bit Linux (e.g.
1209 DN_MULTISHOT with F_NOTIFY).
1210
Antoine Pitrou716c4442009-05-23 19:04:03 +00001211- Issue #5761: Add the name of the underlying file to the repr() of various

1218 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1219 a process identifier type wider than the standard C integer type.
1220
R. David Murray87e20742009-05-23 01:30:26 +00001221- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1232
Antoine Pitroue4501852009-05-14 18:55:55 +00001233- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1234 library. This means, for example, that opening an UTF-16 text file in
1235 append mode doesn't add a BOM at the end of the file if the file isn't
1236 empty.
1237
R. David Murray74b89242009-05-13 17:33:03 +00001238- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1239 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1240 corrects a pydoc regression.
1241
R. David Murray99352742009-05-07 18:24:38 +00001242- Issue 5955: aifc's close method did not close the file it wrapped,
1243 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001285
1286Core and Builtins
1287-----------------
1288
Mark Dickinson865e01a2009-05-07 16:37:01 +00001289- Issue #5914: Add new C API function PyOS_string_to_double, and
1290 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1291
Eric Smith741191f2009-05-06 13:08:15 +00001292- Issue #3382: float.__format__, complex.__format__, and %-formatting
1293 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1294 affects nan -> NAN and inf -> INF.
1295
Mark Hammond5a607a32009-05-06 08:04:54 +00001296- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1297 in all operations, including splitdrive, split, etc. splitunc() now issues
1298 a PendingDeprecation warning.
1299
Eric Smith63376222009-05-05 14:04:18 +00001300- Issue #5920: For float.__format__, change the behavior with the
1301 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1302 to be like 'g' but with at least one decimal point and with a
1303 default precision of 12. Previously, the behavior the same but with
1304 a default precision of 6. This more closely matches str(), and
1305 reduces surprises when adding alignment flags to the empty
1306 presentation type. This also affects the new complex.__format__ in
1307 the same way.
1308
Martin v. Löwis011e8422009-05-05 04:43:17 +00001309- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1310
R. David Murrayb18500d2009-05-04 22:59:07 +00001311- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1312 shadowed by classtype's, even if it was None. property now
1313 inserts the __doc__ into the subclass instance __dict__.
1314
Antoine Pitrou244651a2009-05-04 18:56:13 +00001315- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1316 sequences. Patch by Nick Barnes and Victor Stinner.
1317
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001318- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001319
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001320- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1321 received a new method, detach(). detach() disconnects the underlying stream
1322 from the buffer or text IO and returns it.
1323
Mark Dickinson33841c32009-05-01 15:37:04 +00001324- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1325 floats with absolute value over 1e50. Also remove length
1326 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1327 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001328
Eric Smith741191f2009-05-06 13:08:15 +00001329- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001330 format(complex(1, 2./3), '.5') now produces a sensible result.
1331
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001332- Issue #5864: Fix empty format code formatting for floats so that it
1333 never gives more than the requested number of significant digits.
1334
Eric Smith6dc46f52009-04-27 20:39:49 +00001335- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1336 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1337
Eric Smithcc32a112009-04-26 21:35:14 +00001338- Issue #5835: Deprecate PyOS_ascii_formatd.
1339
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001340- Issue #4971: Fix titlecase for characters that are their own
1341 titlecase, but not their own uppercase.
1342
Benjamin Peterson193152c2009-04-25 01:08:45 +00001343- Issue #5283: Setting __class__ in __del__ caused a segfault.
1344
Mark Dickinsonad476da2009-04-23 19:14:16 +00001345- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1346 z involves nans, infs or negative zeros.
1347
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001348- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001349
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001350- Issue #1869 (and many duplicates): make round(x, n) correctly
1351 rounded for a float x, by using the decimal <-> binary conversions
1352 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1353 consistently agrees with format(x, '.2f').
1354
Benjamin Petersonae937c02009-04-18 20:54:08 +00001355- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1356 some builtin types.
1357
Eric Smith0923d1d2009-04-16 20:16:10 +00001358- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1359
Eric Smith35e84722009-04-16 20:21:28 +00001360- Issue #5515: str.format() type 'n' combined with commas and leading
1361 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001362
1363- Implement PEP 378, Format Specifier for Thousands Separator, for
1364 floats.
1365
Mark Dickinson3370cce2009-04-17 22:40:53 +00001366- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001367 1e11, not 1e12. This avoids printing 13 significant digits in
1368 situations where only 12 of them are correct. Example problem
1369 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1370 long time.)
1371
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001372- Issue #1580: On most platforms, use a 'short' float repr: for a
1373 finite float x, repr(x) now outputs a string based on the shortest
1374 sequence of decimal digits that rounds to x. Previous behaviour was
1375 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001376 Another minor difference is that the new repr switches to
1377 exponential notation at 1e16 instead of the previous 1e17; this
1378 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001379
1380 There's a new sys attribute sys.float_repr_style, which takes
1381 the value 'short' to indicate that we're using short float repr,
1382 and 'legacy' if the short float repr isn't available for one
1383 reason or another.
1384
1385 The float repr change involves incorporating David Gay's 'perfect
1386 rounding' code into the Python core (it's in Python/dtoa.c). As a
1387 secondary consequence, all string-to-float and float-to-string
1388 conversions (including all float formatting operations) will be
1389 correctly rounded on these platforms.
1390
1391 See issue 1580 discussions for details of platforms for which
1392 this change does not apply.
1393
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001394- Issue #5759: float() didn't call __float__ on str subclasses.
1395
Georg Brandlabc38772009-04-12 15:51:51 +00001396- The string.maketrans() function is deprecated; there is a new static method
1397 maketrans() on the bytes and bytearray classes. This removes confusion about
1398 the types string.maketrans() is supposed to work with, and mirrors the
1399 methods available on the str class.
1400
R. David Murraydc6da8a2009-04-09 22:16:43 +00001401- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1402 its clarity and its speed.
1403
Matthias Klose091c7b12009-04-07 13:24:27 +00001404- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1405 to avoid compiler warnings.
1406
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001407- Issue #3739: The unicode-internal encoder now reports the number of characters
1408 consumed like any other encoder (instead of the number of bytes).

1544
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001545- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1546 byte, and the 'C' code only accepts a unicode character.
1547
Georg Brandl406b3d82009-04-11 21:24:37 +00001548- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1549 when hitting the recursion limit under certain circumstances.
1550
Brett Cannon0759dd62009-04-01 18:13:07 +00001551- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1552
Georg Brandlab6f2f62009-03-31 04:16:10 +00001553- Fix a segfault when running test_exceptions with coverage, caused by
1554 insufficient checks in accessors of Exception.__context__.
1555
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001556- Issue #5604: non-ASCII characters in module name passed to
1557 imp.find_module() were converted to UTF-8 while the path is
1558 converted to the default filesystem encoding, causing nonsense.

1561
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001562- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1563 the end sys.path, for compatibility with the system install of Python.
1564
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001565- Issue #4688: Add a heuristic so that tuples and dicts containing only
1566 untrackable objects are not tracked by the garbage collector. This can
1567 reduce the size of collections and therefore the garbage collection overhead
1568 on long-running programs, depending on their particular use of datatypes.
1569
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001570- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1582 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1583 and sizeof(Py_UNICODE) == 2.
1584
Eric Smith8ec90442009-03-14 12:29:34 +00001585- Issue #5237: Allow auto-numbered fields in str.format(). For

1587
Antoine Pitrou652e7072009-03-13 19:25:20 +00001588- Issue #5392: when a very low recursion limit was set, the interpreter would
1589 abort with a fatal error after the recursion limit was hit twice.
1590
Matthias Klose042f1332009-04-04 14:32:42 +00001591- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1637
Lars Gustäbel42e00912009-03-22 20:34:29 +00001638- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1639 forever on incomplete input. That caused tarfile.open() to hang when used
1640 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1641 partial bzip2 compressed data.
1642
Mark Dickinson79f52032009-03-17 23:12:51 +00001643- Issue #2110: Add support for thousands separator and 'n' type

1711 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1712 evaluation loop is compiled with a new dispatch mechanism which gives
1713 speedups of up to 20%, depending on the system, on various benchmarks.

1726 type to (void *).
1727
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001728- Issue #4935: The overflow checking code in the expandtabs() method common
1729 to str, bytes and bytearray could be optimized away by the compiler, letting
1730 the interpreter segfault instead of raising an error.
1731
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001732- Issue #3720: Fix a crash when an iterator modifies its class and removes its

1755 previously buffered data). Patch by Dmitry Vasiliev.
1756
Antoine Pitrou05608432009-01-09 18:53:14 +00001757- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1758 flag to work properly. Furthermore, when specifying -u, the text stdout
1759 and stderr streams have line-by-line buffering enabled (the default being
1760 to buffer arbitrary chunks of data).
1761
Raymond Hettinger35631532009-01-09 03:58:09 +00001762- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1763 instead of ints (reducing its size from 4 to 8 times thereby reducing
1764 Python's overall memory).
1765
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001766- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1767 an existing .py counterpart, override the co_filename attributes of all
1768 code objects if the original filename is obsolete (which can happen if the
1769 file has been renamed, moved, or if it is accessed through different paths).
1770 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1771
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001772- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1773 one byte. Also fixes the meaning of len() so that it returns the number of
1774 items, rather than the size in bytes.
1775
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001776- Issue #4075: Use OutputDebugStringW in Py_FatalError.

1786
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001787- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1788 where the tp_hash and tp_dict slots are both NULL.
1789
Georg Brandlccc47b62008-12-28 11:44:14 +00001790- Issue #4759: None is now allowed as the first argument of

2163
Antoine Pitrou08838b62009-01-21 00:55:13 +00002164- Issue #5008: When a file is opened in append mode with the new IO library,
2165 do an explicit seek to the end of file (so that e.g. tell() returns the
2166 file size rather than 0). This is consistent with the behaviour of the
