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

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().

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

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.

Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000339- The internals of the subprocess module on POSIX systems have been replaced
340 by an extension module (_posixsubprocess) so that the fork()+exec() can be
341 done safely without the possibility of deadlock in multithreaded applications.
342
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000343- subprocess.Popen now has restore_signals and start_new_session features.
344 The default of restore_signals=True is a new behavior compared to earlier
345 Python versions. This means that signals such as SIGPIPE are not ignored
346 by default in subprocesses launched by Python (Issue #1652).

408 exception of canonical and is_canonical) now accept instances of int
409 and long wherever a Decimal instance is accepted, and implicitly
410 convert that argument to Decimal. Previously only some arguments
411 were converted.

434 file position when calling `truncate()`. It would previously change the
435 file position to the given argument, which goes against the tradition of
436 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
437
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000438- Issue #7610: Reworked implementation of the internal
439 :class:`zipfile.ZipExtFile` class used to represent files stored inside
440 an archive. The new implementation is significantly faster and can
441 be wrapped in a :class:`io.BufferedReader` object for more speedups.
442 It also solves an issue where interleaved calls to `read()` and
443 `readline()` give wrong results. Patch by Nir Aides.

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000606- Issue #6816: runpy now provides a run_path function that allows Python code
607 to execute file paths that refer to source or compiled Python files as well
608 as zipfiles, directories and other valid sys.path entries that contain a

1020 calling methods on the object.
1021
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001022- Issue #7222: Make thread "reaping" more reliable so that reference
1023 leak-chasing test runs give sensible results. The previous method of
1024 reaping threads could return successfully while some Thread objects were
1025 still referenced. This also introduces a new private function:
1026 :func:`_thread._count()`.
1027
R. David Murray27144602009-10-19 15:26:16 +00001028- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1030
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001031- Issue #7055: test___all__ now greedily detects all modules which have an

1039
Brett Cannon3c273842009-07-20 00:14:29 +00001040- Fixed tests in importlib.test.source.test_abc_loader that were masking
1041 the proper exceptions that should be raised for missing or improper code
1042 object bytecode.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001205- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1206 (1) inf and nan strings with trailing whitespace were incorrectly
1207 rejected; (2) parsing of strings representing infinities and nans
1208 was locale aware; and (3) the interpretation of fromhex('-nan')
1209 didn't match that of float('-nan').

1312Core and Builtins
1313-----------------
1314
Mark Dickinson865e01a2009-05-07 16:37:01 +00001315- Issue #5914: Add new C API function PyOS_string_to_double, and
1316 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1317
Eric Smith741191f2009-05-06 13:08:15 +00001318- Issue #3382: float.__format__, complex.__format__, and %-formatting
1319 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1320 affects nan -> NAN and inf -> INF.
1321
Mark Hammond5a607a32009-05-06 08:04:54 +00001322- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1323 in all operations, including splitdrive, split, etc. splitunc() now issues
1324 a PendingDeprecation warning.
1325
Eric Smith63376222009-05-05 14:04:18 +00001326- Issue #5920: For float.__format__, change the behavior with the
1327 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1328 to be like 'g' but with at least one decimal point and with a
1329 default precision of 12. Previously, the behavior the same but with
1330 a default precision of 6. This more closely matches str(), and
1331 reduces surprises when adding alignment flags to the empty
1332 presentation type. This also affects the new complex.__format__ in
1333 the same way.
1334
Martin v. Löwis011e8422009-05-05 04:43:17 +00001335- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1336
R. David Murrayb18500d2009-05-04 22:59:07 +00001337- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1338 shadowed by classtype's, even if it was None. property now
1339 inserts the __doc__ into the subclass instance __dict__.
1340
Antoine Pitrou244651a2009-05-04 18:56:13 +00001341- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1342 sequences. Patch by Nick Barnes and Victor Stinner.
1343
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001344- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001345
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001346- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1347 received a new method, detach(). detach() disconnects the underlying stream
1348 from the buffer or text IO and returns it.
1349
Mark Dickinson33841c32009-05-01 15:37:04 +00001350- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1351 floats with absolute value over 1e50. Also remove length
1352 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1353 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001354
Eric Smith741191f2009-05-06 13:08:15 +00001355- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001356 format(complex(1, 2./3), '.5') now produces a sensible result.
1357
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001358- Issue #5864: Fix empty format code formatting for floats so that it
1359 never gives more than the requested number of significant digits.
1360
Eric Smith6dc46f52009-04-27 20:39:49 +00001361- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1362 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1363
Eric Smithcc32a112009-04-26 21:35:14 +00001364- Issue #5835: Deprecate PyOS_ascii_formatd.
1365
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001366- Issue #4971: Fix titlecase for characters that are their own
1367 titlecase, but not their own uppercase.
1368
Benjamin Peterson193152c2009-04-25 01:08:45 +00001369- Issue #5283: Setting __class__ in __del__ caused a segfault.
1370
Mark Dickinsonad476da2009-04-23 19:14:16 +00001371- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1372 z involves nans, infs or negative zeros.
1373
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001374- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001375
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001376- Issue #1869 (and many duplicates): make round(x, n) correctly
1377 rounded for a float x, by using the decimal <-> binary conversions
1378 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1379 consistently agrees with format(x, '.2f').
1380
Benjamin Petersonae937c02009-04-18 20:54:08 +00001381- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1382 some builtin types.
1383
Eric Smith0923d1d2009-04-16 20:16:10 +00001384- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1385
Eric Smith35e84722009-04-16 20:21:28 +00001386- Issue #5515: str.format() type 'n' combined with commas and leading
1387 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001388
1389- Implement PEP 378, Format Specifier for Thousands Separator, for
1390 floats.
1391
Mark Dickinson3370cce2009-04-17 22:40:53 +00001392- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001393 1e11, not 1e12. This avoids printing 13 significant digits in
1394 situations where only 12 of them are correct. Example problem
1395 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1396 long time.)
1397
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001398- Issue #1580: On most platforms, use a 'short' float repr: for a
1399 finite float x, repr(x) now outputs a string based on the shortest
1400 sequence of decimal digits that rounds to x. Previous behaviour was
1401 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001402 Another minor difference is that the new repr switches to
1403 exponential notation at 1e16 instead of the previous 1e17; this
1404 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001405
1406 There's a new sys attribute sys.float_repr_style, which takes
1407 the value 'short' to indicate that we're using short float repr,
1408 and 'legacy' if the short float repr isn't available for one
1409 reason or another.
1410
1411 The float repr change involves incorporating David Gay's 'perfect
1412 rounding' code into the Python core (it's in Python/dtoa.c). As a
1413 secondary consequence, all string-to-float and float-to-string
1414 conversions (including all float formatting operations) will be
1415 correctly rounded on these platforms.
1416
1417 See issue 1580 discussions for details of platforms for which
1418 this change does not apply.
1419
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001420- Issue #5759: float() didn't call __float__ on str subclasses.
1421
Georg Brandlabc38772009-04-12 15:51:51 +00001422- The string.maketrans() function is deprecated; there is a new static method
1423 maketrans() on the bytes and bytearray classes. This removes confusion about
1424 the types string.maketrans() is supposed to work with, and mirrors the
1425 methods available on the str class.
1426
R. David Murraydc6da8a2009-04-09 22:16:43 +00001427- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1428 its clarity and its speed.
1429
Matthias Klose091c7b12009-04-07 13:24:27 +00001430- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1431 to avoid compiler warnings.
1432
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001433- Issue #3739: The unicode-internal encoder now reports the number of characters
1434 consumed like any other encoder (instead of the number of bytes).

1513 results in a handle_expt_event call, not handle_read_event, and POLLERR
1514 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1515 dispatcher now has an 'ignore_log_types' attribute for suppressing
1516 log messages, which is set to 'warning' by default.

1592 untrackable objects are not tracked by the garbage collector. This can
1593 reduce the size of collections and therefore the garbage collection overhead
1594 on long-running programs, depending on their particular use of datatypes.

Lars Gustäbel42e00912009-03-22 20:34:29 +00001664- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1665 forever on incomplete input. That caused tarfile.open() to hang when used
1666 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1667 partial bzip2 compressed data.

1784 flag to work properly. Furthermore, when specifying -u, the text stdout
1785 and stderr streams have line-by-line buffering enabled (the default being
1786 to buffer arbitrary chunks of data).
1787
Raymond Hettinger35631532009-01-09 03:58:09 +00001788- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

1858 object also got a new readonly attribute ``closefd``.

1868 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1869 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1870 of using the replace error handler in PyUnicode_DecodeUTF8().

2191 do an explicit seek to the end of file (so that e.g. tell() returns the
