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().

66 deprecations.
67
Antoine Pitrou05b7c562010-02-02 22:47:00 +000068- Issue #7385: Fix a crash in `MemoryView_FromObject` when
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.

Mark Dickinsonde604012010-01-01 19:27:32 +0000263- Issue #5080: The argument parsing functions PyArg_ParseTuple,
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.

279 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
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.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000284

302-------
303
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000304- Issue #7279: Comparisons involving a Decimal signaling NaN now
305 signal InvalidOperation instead of returning False. (Comparisons
306 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
307 are now hashable; Decimal signaling NaNs remain unhashable.
308
309- Issue #2531: Comparison operations between floats and Decimal
310 instances now return a result based on the numeric values of the
311 operands; previously they returned an arbitrary result based on

Barry Warsawd5f9bf52010-03-31 21:36:22 +0000316- Issue #8233: When run as a script, py_compile.py optionally takes a single
317 argument `-` which tells it to read files to compile from stdin. Each line
318 is read on demand and the named file is compiled immediately. (Original
319 patch by Piotr Ożarowski).

325
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000326- Comparisons using one of <, <=, >, >= between a complex instance and
327 a Fractions instance now raise TypeError instead of returning
328 True/False. This makes Fraction <=> complex comparisons consistent with
329 int <=> complex, float <=> complex, and complex <=> complex comparisons.

Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000372- The internals of the subprocess module on POSIX systems have been replaced
373 by an extension module (_posixsubprocess) so that the fork()+exec() can be
374 done safely without the possibility of deadlock in multithreaded applications.
375
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000376- subprocess.Popen now has restore_signals and start_new_session features.
377 The default of restore_signals=True is a new behavior compared to earlier
378 Python versions. This means that signals such as SIGPIPE are not ignored
379 by default in subprocesses launched by Python (Issue #1652).

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

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

640 to execute file paths that refer to source or compiled Python files as well
641 as zipfiles, directories and other valid sys.path entries that contain a

643 support the same flexibility as the CPython command line itself.

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

1046 a test fails. Can be combined with -j.
1047
Antoine Pitrou060cee22009-11-13 16:29:04 +00001048- Issue #6551: test_zipimport could import and then destroy some modules of
1049 the encodings package, which would make other tests fail further down
1050 the road because the internally cached encoders and decoders would point
1051 to empty global variables.

1059 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1060 between concurrent executions on the same system.
1061
Brett Cannon0ae45112009-11-05 01:17:22 +00001062- Issue #7248: In importlib.test.source.util a try/finally block did not make
1063 sure that some referenced objects actually were created in the block before
1064 calling methods on the object.
1065
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001066- Issue #7222: Make thread "reaping" more reliable so that reference
1067 leak-chasing test runs give sensible results. The previous method of
1068 reaping threads could return successfully while some Thread objects were
1069 still referenced. This also introduces a new private function:
1070 :func:`_thread._count()`.
1071
R. David Murray27144602009-10-19 15:26:16 +00001072- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1073 longer runs the risk of causing the worker thread to fail.
1074
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001075- Issue #7055: test___all__ now greedily detects all modules which have an
1076 __all__ attribute, rather than using a hardcoded and incomplete list.

R. David Murray0bc11ae2009-10-18 22:18:17 +00001078- Issue #7058: Added save/restore for things like sys.argv and cwd to
1079 runtest_inner in regrtest, with warnings if the called test modifies them,
1080 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001081
Mark Dickinson2e304402009-10-04 18:43:54 +00001082- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1083
Brett Cannon3c273842009-07-20 00:14:29 +00001084- Fixed tests in importlib.test.source.test_abc_loader that were masking
1085 the proper exceptions that should be raised for missing or improper code
1086 object bytecode.
1087
Brett Cannonb49c70c2009-07-15 04:08:33 +00001088- Removed importlib's custom test discovery code and switched to
1089 unittest.TestLoader.discover().

1226
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00001227- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
1228 of the command line.
1229
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00001230- Issue #6012: Add cleanup support to O& argument parsing.
1231
Eric Smith41669ca2009-05-23 14:23:22 +00001232- Issue #6089: Fixed str.format with certain invalid field specifiers
1233 that would raise SystemError.
1234
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001235- Issue #5982: staticmethod and classmethod now expose the wrapped
1236 function with __func__.
1237
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001238- Added support for multiple context managers in the same with-statement.
1239 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00001240
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001241- Issue #5829: complex("1e500") no longer raises OverflowError. This
1242 makes it consistent with float("1e500") and interpretation of real
1243 and imaginary literals.
1244
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001245- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1246

1248
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001249- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1250 (1) inf and nan strings with trailing whitespace were incorrectly
1251 rejected; (2) parsing of strings representing infinities and nans
1252 was locale aware; and (3) the interpretation of fromhex('-nan')
1253 didn't match that of float('-nan').

1261
R. David Murray1f1b9d32009-05-27 20:56:59 +00001262- Issue #6121: pydoc now ignores leading and trailing spaces in the
1263 argument to the 'help' function.
1264
Georg Brandlfaf41492009-05-26 18:31:11 +00001265- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1266 arguments for strings with a space in them.
1267
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001268- collections.namedtuple() was not working with the following field
1269 names: cls, self, tuple, itemgetter, and property.
1270
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001271- In unittest, using a skipping decorator on a class is now equivalent to
1272 skipping every test on the class. The ClassTestSuite class has been removed.
1273
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001274- Issue #6050: Don't fail extracting a directory from a zipfile if
1275 the directory already exists.
1276
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001277- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1278 than an int, which makes some operations possible under 64-bit Linux (e.g.
1279 DN_MULTISHOT with F_NOTIFY).
1280
Antoine Pitrou716c4442009-05-23 19:04:03 +00001281- Issue #5761: Add the name of the underlying file to the repr() of various
1282 IO objects.
1283
R. David Murraycaa27b72009-05-23 18:49:56 +00001284- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1285 by Musashi Tamura, tests by Marcin Bachry.
1286
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001287- Issue #1983: Fix functions taking or returning a process identifier to use
1288 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1289 a process identifier type wider than the standard C integer type.
1290
R. David Murray87e20742009-05-23 01:30:26 +00001291- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

Antoine Pitrou2ca24f02009-05-14 21:30:46 +00001301- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
1302
Antoine Pitroue4501852009-05-14 18:55:55 +00001303- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1304 library. This means, for example, that opening an UTF-16 text file in
1305 append mode doesn't add a BOM at the end of the file if the file isn't
1306 empty.
1307
R. David Murray74b89242009-05-13 17:33:03 +00001308- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1309 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1310 corrects a pydoc regression.
1311
R. David Murray99352742009-05-07 18:24:38 +00001312- Issue 5955: aifc's close method did not close the file it wrapped,
1313 now it does. This also means getfp method now returns the real fp.
1314
Benjamin Peterson932073a2009-05-23 16:14:33 +00001315Installation
1316------------
1317
1318- Issue #6047: fullinstall has been removed because Python 3's executable will
1319 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001320
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00001321- Lib/smtpd.py is no longer installed as a script.

1343-----
1344
1345- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
1346 tests on darwin even when the OS was installed on a case-sensitive
1347 filesystem. Also fixed tests that should not be run when
1348 sys.dont_write_bytecode is true.

1350
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001351What's New in Python 3.1 beta 1?
1352================================
1353
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001354*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001355
1356Core and Builtins
1357-----------------
1358
Mark Dickinson865e01a2009-05-07 16:37:01 +00001359- Issue #5914: Add new C API function PyOS_string_to_double, and
1360 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1361
Eric Smith741191f2009-05-06 13:08:15 +00001362- Issue #3382: float.__format__, complex.__format__, and %-formatting
1363 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1364 affects nan -> NAN and inf -> INF.
1365
Mark Hammond5a607a32009-05-06 08:04:54 +00001366- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1367 in all operations, including splitdrive, split, etc. splitunc() now issues
1368 a PendingDeprecation warning.
1369
Eric Smith63376222009-05-05 14:04:18 +00001370- Issue #5920: For float.__format__, change the behavior with the
1371 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1372 to be like 'g' but with at least one decimal point and with a
1373 default precision of 12. Previously, the behavior the same but with
1374 a default precision of 6. This more closely matches str(), and
1375 reduces surprises when adding alignment flags to the empty
1376 presentation type. This also affects the new complex.__format__ in
1377 the same way.
1378
Martin v. Löwis011e8422009-05-05 04:43:17 +00001379- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1380
R. David Murrayb18500d2009-05-04 22:59:07 +00001381- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1382 shadowed by classtype's, even if it was None. property now
1383 inserts the __doc__ into the subclass instance __dict__.
1384
Antoine Pitrou244651a2009-05-04 18:56:13 +00001385- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1386 sequences. Patch by Nick Barnes and Victor Stinner.
1387
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001388- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001389
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001390- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1391 received a new method, detach(). detach() disconnects the underlying stream
1392 from the buffer or text IO and returns it.
1393
Mark Dickinson33841c32009-05-01 15:37:04 +00001394- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1395 floats with absolute value over 1e50. Also remove length
1396 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1397 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001398
Eric Smith741191f2009-05-06 13:08:15 +00001399- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001400 format(complex(1, 2./3), '.5') now produces a sensible result.
1401
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001402- Issue #5864: Fix empty format code formatting for floats so that it
1403 never gives more than the requested number of significant digits.
1404
Eric Smith6dc46f52009-04-27 20:39:49 +00001405- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1406 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1407
Eric Smithcc32a112009-04-26 21:35:14 +00001408- Issue #5835: Deprecate PyOS_ascii_formatd.
1409
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001410- Issue #4971: Fix titlecase for characters that are their own
1411 titlecase, but not their own uppercase.
1412
Benjamin Peterson193152c2009-04-25 01:08:45 +00001413- Issue #5283: Setting __class__ in __del__ caused a segfault.
1414
Mark Dickinsonad476da2009-04-23 19:14:16 +00001415- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1416 z involves nans, infs or negative zeros.
1417
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001418- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001419
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001420- Issue #1869 (and many duplicates): make round(x, n) correctly
1421 rounded for a float x, by using the decimal <-> binary conversions
1422 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1423 consistently agrees with format(x, '.2f').
1424
Benjamin Petersonae937c02009-04-18 20:54:08 +00001425- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1426 some builtin types.
1427
Eric Smith0923d1d2009-04-16 20:16:10 +00001428- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1429
Eric Smith35e84722009-04-16 20:21:28 +00001430- Issue #5515: str.format() type 'n' combined with commas and leading
1431 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001432
1433- Implement PEP 378, Format Specifier for Thousands Separator, for
1434 floats.
1435
Mark Dickinson3370cce2009-04-17 22:40:53 +00001436- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001437 1e11, not 1e12. This avoids printing 13 significant digits in
1438 situations where only 12 of them are correct. Example problem
1439 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1440 long time.)
1441
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001442- Issue #1580: On most platforms, use a 'short' float repr: for a
1443 finite float x, repr(x) now outputs a string based on the shortest
1444 sequence of decimal digits that rounds to x. Previous behaviour was
1445 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001446 Another minor difference is that the new repr switches to
1447 exponential notation at 1e16 instead of the previous 1e17; this
1448 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001449
1450 There's a new sys attribute sys.float_repr_style, which takes
1451 the value 'short' to indicate that we're using short float repr,
1452 and 'legacy' if the short float repr isn't available for one
1453 reason or another.
1454
1455 The float repr change involves incorporating David Gay's 'perfect
1456 rounding' code into the Python core (it's in Python/dtoa.c). As a
1457 secondary consequence, all string-to-float and float-to-string
1458 conversions (including all float formatting operations) will be
1459 correctly rounded on these platforms.
1460
1461 See issue 1580 discussions for details of platforms for which
1462 this change does not apply.
1463
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001464- Issue #5759: float() didn't call __float__ on str subclasses.
1465
Georg Brandlabc38772009-04-12 15:51:51 +00001466- The string.maketrans() function is deprecated; there is a new static method
1467 maketrans() on the bytes and bytearray classes. This removes confusion about
1468 the types string.maketrans() is supposed to work with, and mirrors the
1469 methods available on the str class.
1470
R. David Murraydc6da8a2009-04-09 22:16:43 +00001471- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1472 its clarity and its speed.
1473
Matthias Klose091c7b12009-04-07 13:24:27 +00001474- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1475 to avoid compiler warnings.
1476
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001477- Issue #3739: The unicode-internal encoder now reports the number of characters
1478 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001798- Issue #4935: The overflow checking code in the expandtabs() method common
1799 to str, bytes and bytearray could be optimized away by the compiler, letting
1800 the interpreter segfault instead of raising an error.
1801
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001802- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1803 __next__ method.
1804
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001805- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1806 function no longer attempt to call the __long__ slot to convert an object
1807 to an integer. Only the __int__ and __trunc__ slots are examined.

1812
Antoine Pitrouab868312009-01-10 15:40:25 +00001813- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1814 common cases are optimized thanks to a dedicated fast path and a moderate
1815 amount of loop unrolling.
1816
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001817- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1818 collecting the oldest generation) so that allocating lots of objects without
1819 destroying them does not show quadratic performance. Based on a proposal by
1820 Martin von Löwis at
1821 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1822
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001823- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001824 having been closed (for instance, a read() call could return some
1825 previously buffered data). Patch by Dmitry Vasiliev.
1826
Antoine Pitrou05608432009-01-09 18:53:14 +00001827- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1828 flag to work properly. Furthermore, when specifying -u, the text stdout
1829 and stderr streams have line-by-line buffering enabled (the default being
1830 to buffer arbitrary chunks of data).
1831
Raymond Hettinger35631532009-01-09 03:58:09 +00001832- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1833 instead of ints (reducing its size from 4 to 8 times thereby reducing
1834 Python's overall memory).
1835
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001836- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1837 an existing .py counterpart, override the co_filename attributes of all
1838 code objects if the original filename is obsolete (which can happen if the
1839 file has been renamed, moved, or if it is accessed through different paths).
1840 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1841
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001842- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1843 one byte. Also fixes the meaning of len() so that it returns the number of
1844 items, rather than the size in bytes.
1845
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001846- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1847
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001848- Issue #4747: When the terminal does not use utf-8, executing a script with
1849 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1850
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001851- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

Antoine Pitrou7ddda782009-01-01 15:35:33 +00001854- Issue #3680: Reference cycles created through a dict, set or deque iterator
1855 did not get collected.
1856
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001857- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1858 where the tp_hash and tp_dict slots are both NULL.
1859
Georg Brandlccc47b62008-12-28 11:44:14 +00001860- Issue #4759: None is now allowed as the first argument of
1861 bytearray.translate(). It was always allowed for bytes.translate().
1862
Skip Montanaro80072cb2008-12-23 03:51:14 +00001863- Added test case to ensure attempts to read from a file opened for writing
1864 fail.
1865
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001866- Issue #3106: Speedup some comparisons (str/str and int/int).

1870
Antoine Pitrou621601a2008-12-17 23:18:19 +00001871- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1876
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001877- Issue #2173: When getting device encoding, check that return value of
1878 nl_langinfo is not the empty string. This was causing silent build
1879 failures on OS X.
1880
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001881- Issue #4597: Fixed several opcodes that weren't always propagating
1882 exceptions.
1883
1884- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001885 context manager returns a value that cannot be converted to a bool.
1886
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001887- Issue #4445: Replace "sizeof(PyBytesObject)" with
1888 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1889 bytes instances. On a typical machine this saves 3 bytes of memory
1890 (on average) per allocation of a bytes instance.
1891
Christian Heimesa872de52008-12-05 08:26:55 +00001892- Issue #4533: File read operation was dreadfully slow due to a slowly
1893 growing read buffer. Fixed by using the same growth rate algorithm as
1894 Python 2.x.
1895
Antoine Pitrou5504e892008-12-06 21:27:53 +00001896- Issue #4509: Various issues surrounding resize of bytearray objects to
1897 which there are buffer exports (e.g. memoryview instances).
1898
Georg Brandlf9734072008-12-07 15:30:06 +00001899- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1900 method on file objects with closefd=False. The file descriptor is still
1901 kept open but the file object behaves like a closed file. The ``FileIO``
1902 object also got a new readonly attribute ``closefd``.

1910
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001911- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1912 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1913 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1914 of using the replace error handler in PyUnicode_DecodeUTF8().
