Victor Stinner00d6a1d2010-03-25 01:02:29 +000015- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
16 optimizations are disabled when --with-pydebug is used.
17
Victor Stinner120c2122010-03-25 00:30:28 +000018- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
19 is unknown
20

24 PyMemberDefs could produce an internal error; raise TypeError instead.
25
Mark Dickinsonf673f0c2010-03-13 09:48:39 +000026- Issue #7845: Rich comparison methods on the complex type now return
27 NotImplemented rather than raising a TypeError when comparing with an
28 incompatible type; this allows user-defined classes to implement their own
29 comparisons with complex.
30
Victor Stinner52f6dd72010-03-12 14:45:56 +000031- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
32 (SIGINT). If an error occurs while importing the site module, the error is
33 printed and Python exits. Initialize the GIL before importing the site
34 module.
35
Benjamin Petersonae5f2f42010-03-07 17:10:51 +000036- Issue #7173: Generator finalization could invalidate sys.exc_info().

42 the BOM check fails.
43
Benjamin Peterson23e018a2010-02-27 17:40:01 +000044- Handle errors from looking up __prepare__ correctly.
45
Larry Hastings1373a072010-02-24 22:49:58 +000046- Issue #5939: Add additional runtime checking to ensure a valid capsule

60 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
61 and PyOS_string_to_double instead. See issue #5835 for the original
62 deprecations.
63
Antoine Pitrou05b7c562010-02-02 22:47:00 +000064- Issue #7385: Fix a crash in `MemoryView_FromObject` when
65 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
66
Mark Dickinsonbc099642010-01-29 17:27:24 +000067- Issue #7788: Fix an interpreter crash produced by deleting a list
68 slice with very large step value.
69
Eric Smithf7bb5782010-01-27 00:44:57 +000070- Issue #7766: Change sys.getwindowsversion() return value to a named
71 tuple and add the additional members returned in an OSVERSIONINFOEX
72 structure. The new members are service_pack_major, service_pack_minor,
73 suite_mask, and product_type.
74
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000075- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
76 could crash in many places because of the PyByteArray_AS_STRING() macro
77 returning NULL. The macro now returns a statically allocated empty
78 string instead.
79
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000080- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
81 where the right hand operand is a set of constants, by turning the set into
82 a frozenset and pre-building it as a constant. The comparison operation
83 is made against the constant instead of building a new set each time it is
84 executed (a similar optimization already existed which turned a list of
85 constants into a pre-built tuple). Patch and additional tests by Dave
86 Malcolm.
87
Antoine Pitrouf2c54842010-01-13 08:07:53 +000088- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
89 methods of bytes, bytearray and unicode objects by using a common
90 implementation based on stringlib's fast search. Patch by Florent Xicluna.
91
Mark Dickinson45b63652010-01-16 18:10:25 +000092- Issue #7632: Fix various str -> float conversion bugs present in 2.7
93 alpha 2, including: (1) a serious 'wrong output' bug that could
94 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
95 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000096 strings corresponding to subnormal values, (3) a memory leak for
97 some values large enough to cause overflow, and (4) a number of
98 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000099
Benjamin Petersonaea44282010-01-04 01:10:28 +0000100- The __complex__ method is now looked up on the class of instances to make it

Mark Dickinson9ab44b52009-12-30 16:22:49 +0000109- Issue #7534: Fix handling of IEEE specials (infinities, nans,
110 negative zero) in ** operator. The behaviour now conforms to that
111 described in C99 Annex F.
112
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000113- Issue #1811: improve accuracy and cross-platform consistency for
114 true division of integers: the result of a/b is now correctly
115 rounded for ints a and b (at least on IEEE 754 platforms), and in
116 particular does not depend on the internal representation of an int.
117
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000118- Issue #6834: replace the implementation for the 'python' and 'pythonw'
119 executables on OSX.
120
121 These executables now work properly with the arch(1) command:
122 ``arch -ppc python`` will start a universal binary version of python
123 in PPC mode (unlike previous releases).
124
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000125- Issue #7466: segmentation fault when the garbage collector is called

132 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
133
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000134- Issue #7085: Fix crash when importing some extensions in a thread
135 on MacOSX 10.6.

140 implement the relevant rich comparison methods.
141
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000142- Issue #7298: fixes for range and reversed(range(...)). Iteration
143 over range(a, b, c) incorrectly gave an empty iterator when a, b and
144 c fit in C long but the length of the range did not. Also fix
145 several cases where reversed(range(a, b, c)) gave wrong results, and
146 fix a refleak for reversed(range(a, b, c)) with large arguments.
147
Raymond Hettingerfc438512009-11-01 20:55:33 +0000148- Issue #7244: itertools.izip_longest() no longer ignores exceptions

187 and include information from the Unihan.txt file.
188
Mark Dickinson2683ab02009-09-29 19:21:35 +0000189- Issue #7019: Raise ValueError when unmarshalling bad long data, instead
190 of producing internally inconsistent Python longs.

256 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
257 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
258 DeprecationWarning for float arguments passed with the 'L' format
259 code. This will become a TypeError in a future version of Python,
260 to match the behaviour of the other integer format codes.
261
Georg Brandl1e28a272009-12-28 08:41:01 +0000262- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

272 should used for accessing the d_type and d_name members of structures
273 using PyDescr_COMMON.
274
275- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000276

294-------
295
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000296- Comparisons using one of <, <=, >, >= between a complex instance and
297 a Fractions instance now raise TypeError instead of returning
298 True/False. This makes Fraction <=> complex comparisons consistent with
299 int <=> complex, float <=> complex, and complex <=> complex comparisons.

310 now silenced.
311
R. David Murrayca2edce2010-03-22 17:48:48 +0000312- Issue #7860: platform.uname now reports the correct 'machine' type
313 when Python is running in WOW64 mode on 64 bit Windows.
314

344 done safely without the possibility of deadlock in multithreaded applications.
345
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000346- subprocess.Popen now has restore_signals and start_new_session features.
347 The default of restore_signals=True is a new behavior compared to earlier
348 Python versions. This means that signals such as SIGPIPE are not ignored
349 by default in subprocesses launched by Python (Issue #1652).

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

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

617 default timeout is 20 seconds, which should be amply sufficient for
618 local connections.

633 recursive locks as fast as regular non-recursive locks (previously,
634 they were slower by 10x to 15x).

654 reading from stdin so that existing input does not confuse it and

1005
R. David Murray35768ad2009-11-15 00:23:21 +00001006- Issue #7324: add a sanity check to regrtest argument parsing to

1010 a test fails. Can be combined with -j.
1011
Antoine Pitrou060cee22009-11-13 16:29:04 +00001012- Issue #6551: test_zipimport could import and then destroy some modules of
1013 the encodings package, which would make other tests fail further down
1014 the road because the internally cached encoders and decoders would point
1015 to empty global variables.
1016
Antoine Pitrou941ee882009-11-11 20:59:38 +00001017- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1024 between concurrent executions on the same system.
1025
Brett Cannon0ae45112009-11-05 01:17:22 +00001026- Issue #7248: In importlib.test.source.util a try/finally block did not make
1027 sure that some referenced objects actually were created in the block before
1028 calling methods on the object.
1029
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001030- Issue #7222: Make thread "reaping" more reliable so that reference
1031 leak-chasing test runs give sensible results. The previous method of
1032 reaping threads could return successfully while some Thread objects were
1033 still referenced. This also introduces a new private function:
1034 :func:`_thread._count()`.
1035
R. David Murray27144602009-10-19 15:26:16 +00001036- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1037 longer runs the risk of causing the worker thread to fail.
1038
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001039- Issue #7055: test___all__ now greedily detects all modules which have an
1040 __all__ attribute, rather than using a hardcoded and incomplete list.
1041
R. David Murray0bc11ae2009-10-18 22:18:17 +00001042- Issue #7058: Added save/restore for things like sys.argv and cwd to
1043 runtest_inner in regrtest, with warnings if the called test modifies them,
1044 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001045
Mark Dickinson2e304402009-10-04 18:43:54 +00001046- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1047
Brett Cannon3c273842009-07-20 00:14:29 +00001048- Fixed tests in importlib.test.source.test_abc_loader that were masking
1049 the proper exceptions that should be raised for missing or improper code
1050 object bytecode.
1051
Brett Cannonb49c70c2009-07-15 04:08:33 +00001052- Removed importlib's custom test discovery code and switched to
1053 unittest.TestLoader.discover().

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001205- Issue #5829: complex("1e500") no longer raises OverflowError. This
1206 makes it consistent with float("1e500") and interpretation of real
1207 and imaginary literals.
1208

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001213- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1214 (1) inf and nan strings with trailing whitespace were incorrectly
1215 rejected; (2) parsing of strings representing infinities and nans
1216 was locale aware; and (3) the interpretation of fromhex('-nan')
1217 didn't match that of float('-nan').

1320Core and Builtins
1321-----------------
1322
Mark Dickinson865e01a2009-05-07 16:37:01 +00001323- Issue #5914: Add new C API function PyOS_string_to_double, and
1324 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1325
Eric Smith741191f2009-05-06 13:08:15 +00001326- Issue #3382: float.__format__, complex.__format__, and %-formatting
1327 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1328 affects nan -> NAN and inf -> INF.
1329
Mark Hammond5a607a32009-05-06 08:04:54 +00001330- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1331 in all operations, including splitdrive, split, etc. splitunc() now issues
1332 a PendingDeprecation warning.
1333
Eric Smith63376222009-05-05 14:04:18 +00001334- Issue #5920: For float.__format__, change the behavior with the
1335 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1336 to be like 'g' but with at least one decimal point and with a
1337 default precision of 12. Previously, the behavior the same but with
1338 a default precision of 6. This more closely matches str(), and
1339 reduces surprises when adding alignment flags to the empty
1340 presentation type. This also affects the new complex.__format__ in
1341 the same way.
1342
Martin v. Löwis011e8422009-05-05 04:43:17 +00001343- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1344
R. David Murrayb18500d2009-05-04 22:59:07 +00001345- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1346 shadowed by classtype's, even if it was None. property now
1347 inserts the __doc__ into the subclass instance __dict__.
1348
Antoine Pitrou244651a2009-05-04 18:56:13 +00001349- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1350 sequences. Patch by Nick Barnes and Victor Stinner.
1351
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001352- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001353
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001354- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1355 received a new method, detach(). detach() disconnects the underlying stream
1356 from the buffer or text IO and returns it.
1357
Mark Dickinson33841c32009-05-01 15:37:04 +00001358- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1359 floats with absolute value over 1e50. Also remove length
1360 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1361 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001362
Eric Smith741191f2009-05-06 13:08:15 +00001363- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001364 format(complex(1, 2./3), '.5') now produces a sensible result.
1365
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001366- Issue #5864: Fix empty format code formatting for floats so that it
1367 never gives more than the requested number of significant digits.
1368
Eric Smith6dc46f52009-04-27 20:39:49 +00001369- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1370 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1371
Eric Smithcc32a112009-04-26 21:35:14 +00001372- Issue #5835: Deprecate PyOS_ascii_formatd.
1373
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001374- Issue #4971: Fix titlecase for characters that are their own
1375 titlecase, but not their own uppercase.
1376
Benjamin Peterson193152c2009-04-25 01:08:45 +00001377- Issue #5283: Setting __class__ in __del__ caused a segfault.
1378
Mark Dickinsonad476da2009-04-23 19:14:16 +00001379- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1380 z involves nans, infs or negative zeros.
1381
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001382- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001383
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001384- Issue #1869 (and many duplicates): make round(x, n) correctly
1385 rounded for a float x, by using the decimal <-> binary conversions
1386 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1387 consistently agrees with format(x, '.2f').
1388
Benjamin Petersonae937c02009-04-18 20:54:08 +00001389- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1390 some builtin types.
1391
Eric Smith0923d1d2009-04-16 20:16:10 +00001392- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1393
Eric Smith35e84722009-04-16 20:21:28 +00001394- Issue #5515: str.format() type 'n' combined with commas and leading
1395 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001396
1397- Implement PEP 378, Format Specifier for Thousands Separator, for
1398 floats.
1399
Mark Dickinson3370cce2009-04-17 22:40:53 +00001400- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001401 1e11, not 1e12. This avoids printing 13 significant digits in
1402 situations where only 12 of them are correct. Example problem
1403 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1404 long time.)
1405
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001406- Issue #1580: On most platforms, use a 'short' float repr: for a
1407 finite float x, repr(x) now outputs a string based on the shortest
1408 sequence of decimal digits that rounds to x. Previous behaviour was
1409 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001410 Another minor difference is that the new repr switches to
1411 exponential notation at 1e16 instead of the previous 1e17; this
1412 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001413
1414 There's a new sys attribute sys.float_repr_style, which takes
1415 the value 'short' to indicate that we're using short float repr,
1416 and 'legacy' if the short float repr isn't available for one
1417 reason or another.
1418
1419 The float repr change involves incorporating David Gay's 'perfect
1420 rounding' code into the Python core (it's in Python/dtoa.c). As a
1421 secondary consequence, all string-to-float and float-to-string
1422 conversions (including all float formatting operations) will be
1423 correctly rounded on these platforms.
1424
1425 See issue 1580 discussions for details of platforms for which
1426 this change does not apply.
1427
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001428- Issue #5759: float() didn't call __float__ on str subclasses.
1429
Georg Brandlabc38772009-04-12 15:51:51 +00001430- The string.maketrans() function is deprecated; there is a new static method
1431 maketrans() on the bytes and bytearray classes. This removes confusion about
1432 the types string.maketrans() is supposed to work with, and mirrors the
1433 methods available on the str class.
1434
R. David Murraydc6da8a2009-04-09 22:16:43 +00001435- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1436 its clarity and its speed.
1437
Matthias Klose091c7b12009-04-07 13:24:27 +00001438- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1439 to avoid compiler warnings.
1440
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001441- Issue #3739: The unicode-internal encoder now reports the number of characters
1442 consumed like any other encoder (instead of the number of bytes).

1521 results in a handle_expt_event call, not handle_read_event, and POLLERR
1522 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1523 dispatcher now has an 'ignore_log_types' attribute for suppressing

Antoine Pitrou3a652b12009-03-23 18:52:06 +00001599- Issue #4688: Add a heuristic so that tuples and dicts containing only
1600 untrackable objects are not tracked by the garbage collector. This can
1601 reduce the size of collections and therefore the garbage collection overhead
1602 on long-running programs, depending on their particular use of datatypes.

1609 2**15 for the internal representation of integers, for performance
1610 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1611 --enable-big-digits option to configure, which overrides the
1612 default. Add sys.int_info structseq to provide information about
1613 the internal format.

1616 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1617 and sizeof(Py_UNICODE) == 2.
1618
Eric Smith8ec90442009-03-14 12:29:34 +00001619- Issue #5237: Allow auto-numbered fields in str.format(). For

1621
Antoine Pitrou652e7072009-03-13 19:25:20 +00001622- Issue #5392: when a very low recursion limit was set, the interpreter would
1623 abort with a fatal error after the recursion limit was hit twice.
1624
Matthias Klose042f1332009-04-04 14:32:42 +00001625- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1673 forever on incomplete input. That caused tarfile.open() to hang when used
1674 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1675 partial bzip2 compressed data.

Antoine Pitrou05608432009-01-09 18:53:14 +00001791- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1792 flag to work properly. Furthermore, when specifying -u, the text stdout
1793 and stderr streams have line-by-line buffering enabled (the default being
1794 to buffer arbitrary chunks of data).
1795
Raymond Hettinger35631532009-01-09 03:58:09 +00001796- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1797 instead of ints (reducing its size from 4 to 8 times thereby reducing
1798 Python's overall memory).
1799
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001800- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1801 an existing .py counterpart, override the co_filename attributes of all
1802 code objects if the original filename is obsolete (which can happen if the
1803 file has been renamed, moved, or if it is accessed through different paths).
1804 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1805
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001806- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1807 one byte. Also fixes the meaning of len() so that it returns the number of
1808 items, rather than the size in bytes.
1809

1823
Georg Brandlccc47b62008-12-28 11:44:14 +00001824- Issue #4759: None is now allowed as the first argument of

1826
Skip Montanaro80072cb2008-12-23 03:51:14 +00001827- Added test case to ensure attempts to read from a file opened for writing
1828 fail.

1834
Antoine Pitrou621601a2008-12-17 23:18:19 +00001835- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1842 nl_langinfo is not the empty string. This was causing silent build
1843 failures on OS X.
1844
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001845- Issue #4597: Fixed several opcodes that weren't always propagating

1850
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001851- Issue #4445: Replace "sizeof(PyBytesObject)" with
1852 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1853 bytes instances. On a typical machine this saves 3 bytes of memory
1854 (on average) per allocation of a bytes instance.
1855
Christian Heimesa872de52008-12-05 08:26:55 +00001856- Issue #4533: File read operation was dreadfully slow due to a slowly
1857 growing read buffer. Fixed by using the same growth rate algorithm as
1858 Python 2.x.
1859
Antoine Pitrou5504e892008-12-06 21:27:53 +00001860- Issue #4509: Various issues surrounding resize of bytearray objects to
1861 which there are buffer exports (e.g. memoryview instances).
1862
Georg Brandlf9734072008-12-07 15:30:06 +00001863- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1864 method on file objects with closefd=False. The file descriptor is still
1865 kept open but the file object behaves like a closed file. The ``FileIO``
1866 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001867
Antoine Pitroubc420402008-12-07 20:14:49 +00001868- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1874
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001875- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1876 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1877 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1878 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00002198- Issue #5008: When a file is opened in append mode with the new IO library,
2199 do an explicit seek to the end of file (so that e.g. tell() returns the
