12Core and Builtins
13-----------------
14
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
Victor Stinner808fc0a2010-03-22 12:50:40 +000021- Issue #1583863: An str subclass can now override the __str__ method
22
Mark Dickinsond59b4162010-03-13 11:34:40 +000023- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
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

129 with invalid values.
130
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000131- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
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.
136
Philip Jenvey1309adb2009-11-17 03:43:14 +0000137- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
138
Mark Dickinson6f1d0492009-11-15 13:58:49 +0000139- Issue #6970: Remove redundant calls when comparing objects that don't
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
149 raised during the formation of an output tuple.
150
Benjamin Petersonb2e796a2009-10-28 21:59:39 +0000151- Issue #3297: On wide unicode builds, do not split unicode characters into
152 surrogates.

157
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000158- Support for AtheOS has been completely removed from the code base. It was
159 disabled since Python 3.0.
160
161- Support for several legacy threading libraries has been disabled. These
162 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
163 will be entirely removed in 3.3.
164
Raymond Hettingeraf7adad2009-10-22 11:22:50 +0000165- Peephole constant folding had missed UNARY_POSITIVE.
166
Antoine Pitrou011bd622009-10-20 21:52:47 +0000167- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which

Antoine Pitrou403ce782009-10-14 17:14:16 +0000183
Amaury Forgeot d'Arc7d520792009-10-06 21:03:20 +0000184- Issue #1571184: The Unicode database contains properties for more characters.
185 The tables for code points representing numeric values, white spaces or line
186 breaks are now generated from the official Unicode Character Database files,
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.
191
Philip Jenvey26713ca2009-09-29 04:57:18 +0000192- Issue #6990: Fix threading.local subclasses leaving old state around
193 after a reference cycle GC which could be recycled by new locals.

Mark Dickinson835a6c82009-06-30 15:45:17 +0000224- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
225 This fixes a build failure on HP-UX: int32_t and uint32_t are
226 defined in inttypes.h instead of stdint.h on that platform.
227
Amaury Forgeot d'Arca4aba662009-07-01 00:48:39 +0000228- Issue #6373: Fixed a SystemError when encoding with the latin-1 codec and

233
Alexandre Vassalottieb6f8de2009-12-31 03:56:09 +0000234- Issue #6687: PyBytes_FromObject() no longer accepts an integer as its
235 argument to construct a null-initialized bytes object.
236
Alexandre Vassalottic36c3782010-01-09 20:35:09 +0000237- Issue #1023290: Add from_bytes() and to_bytes() methods to integers.

242 from being pickled properly.
243
Collin Winter4222e9c2010-03-18 22:46:40 +0000244- Code objects now support weak references.
245
Benjamin Peterson466a7822009-07-02 21:44:01 +0000246C-API
247-----
248
Antoine Pitrou8689a102010-04-01 16:53:15 +0000249- Issue #8276: PyEval_CallObject() is now only available in macro form. The
250 function declaration, which was kept for backwards compatibility reasons,

252
Mark Dickinson93f562c2010-01-30 10:30:15 +0000253- Issue #7767: New function PyLong_AsLongLongAndOverflow added,
254 analogous to PyLong_AsLongAndOverflow.
255
Benjamin Peterson8667a9b2010-01-09 21:45:28 +0000256- Make PyUnicode_CompareWithASCIIString return not equal if the Python string
257 has '\0' at the end.
258
Mark Dickinsonde604012010-01-01 19:27:32 +0000259- Issue #5080: The argument parsing functions PyArg_ParseTuple,
260 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
261 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
262 DeprecationWarning for float arguments passed with the 'L' format
263 code. This will become a TypeError in a future version of Python,
264 to match the behaviour of the other integer format codes.
265
Georg Brandl1e28a272009-12-28 08:41:01 +0000266- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

273
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000274- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
275 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
276 should used for accessing the d_type and d_name members of structures
277 using PyDescr_COMMON.
278
279- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000280
Benjamin Peterson466a7822009-07-02 21:44:01 +0000281- The code flags for old __future__ features are now available again.
282
Alexandre Vassalotti7b82b402009-07-21 04:30:03 +0000283- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
284 PyCode_Addr2Line().
285
286- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
287 object at a specified file, function, and line number.
288
289- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
290 ``const char *`` as the string is stored beyond the call.
291
Benjamin Peterson05159c42009-12-03 03:01:27 +0000292- Issue #2422: When compiled with the ``--with-valgrind`` option, the
293 pymalloc allocator will be automatically disabled when running under
294 Valgrind. This gives improved memory leak detection when running
295 under Valgrind, while taking advantage of pymalloc at other times.

298-------
299
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000300- Issue #8233: When run as a script, py_compile.py optionally takes a single
301 argument `-` which tells it to read files to compile from stdin. Each line
302 is read on demand and the named file is compiled immediately. (Original
303 patch by Piotr Ożarowski).
304
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000305- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
306 form feed (0x0C) are now considered linebreaks, as specified in Unicode
307 Standard Annex #14. See issue #7643.
308 http://www.unicode.org/reports/tr14/
309
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000310- Comparisons using one of <, <=, >, >= between a complex instance and
311 a Fractions instance now raise TypeError instead of returning
312 True/False. This makes Fraction <=> complex comparisons consistent with
313 int <=> complex, float <=> complex, and complex <=> complex comparisons.
314
Antoine Pitrou39b35432010-03-23 00:25:54 +0000315- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
316 some methods (such as oss_mixer_device.fileno()) were not available.

361 The default of restore_signals=True is a new behavior compared to earlier

434 in XML processing instructions and comments. These raw characters are
435 allowed by the XML specification, and are necessary when outputting e.g.

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

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

621 the registry under Windows. Patch by Gabriel Genellina.
622
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000623- Issue #6816: runpy now provides a run_path function that allows Python code
624 to execute file paths that refer to source or compiled Python files as well
625 as zipfiles, directories and other valid sys.path entries that contain a
626 __main__.py file. This allows applications that run other Python scripts to
627 support the same flexibility as the CPython command line itself.
628
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000629- Issue #7318: multiprocessing now uses a timeout when it fails to establish
630 a connection with another process, rather than looping endlessly. The
631 default timeout is 20 seconds, which should be amply sufficient for
632 local connections.
633
Antoine Pitrouc63ecee2009-11-10 21:34:48 +0000634- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and

644
Antoine Pitrou434736a2009-11-10 18:46:01 +0000645- Issue #3001: Add a C implementation of recursive locks which is used by
646 default when instantiating a `threading.RLock` object. This makes
647 recursive locks as fast as regular non-recursive locks (previously,
648 they were slower by 10x to 15x).
649

662
Antoine Pitrou03f13442009-11-02 11:36:51 +0000663- Issue #6896: mailbox.Maildir now invalidates its internal cache each time
664 a modification is done through it. This fixes inconsistencies and test
665 failures on systems with slightly bogus mtime behaviour.
666
Gregory P. Smith50467882009-11-01 18:42:17 +0000667- Issue #7246 & Issue #7208: getpass now properly flushes input before
668 reading from stdin so that existing input does not confuse it and
669 lead to incorrect entry or an IOError. It also properly flushes it
670 afterwards to avoid the terminal echoing the input afterwards on
671 OSes such as Solaris.
672
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000673- Issue #7233: Fix a number of two-argument Decimal methods to make

1001
Ezio Melotti184bdfb2010-02-18 09:37:05 +00001002- Issue #7712: test.support gained a new `temp_cwd` context manager which is

1030 a test fails. Can be combined with -j.
1031
Antoine Pitrou060cee22009-11-13 16:29:04 +00001032- Issue #6551: test_zipimport could import and then destroy some modules of
1033 the encodings package, which would make other tests fail further down
1034 the road because the internally cached encoders and decoders would point
1035 to empty global variables.
1036

1043 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1044 between concurrent executions on the same system.
1045
Brett Cannon0ae45112009-11-05 01:17:22 +00001046- Issue #7248: In importlib.test.source.util a try/finally block did not make
1047 sure that some referenced objects actually were created in the block before
1048 calling methods on the object.
1049
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001050- Issue #7222: Make thread "reaping" more reliable so that reference
1051 leak-chasing test runs give sensible results. The previous method of
1052 reaping threads could return successfully while some Thread objects were
1053 still referenced. This also introduces a new private function:
1054 :func:`_thread._count()`.
1055
R. David Murray27144602009-10-19 15:26:16 +00001056- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1057 longer runs the risk of causing the worker thread to fail.
1058
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001059- Issue #7055: test___all__ now greedily detects all modules which have an
1060 __all__ attribute, rather than using a hardcoded and incomplete list.
1061
R. David Murray0bc11ae2009-10-18 22:18:17 +00001062- Issue #7058: Added save/restore for things like sys.argv and cwd to
1063 runtest_inner in regrtest, with warnings if the called test modifies them,
1064 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001065
Mark Dickinson2e304402009-10-04 18:43:54 +00001066- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1067
Brett Cannon3c273842009-07-20 00:14:29 +00001068- Fixed tests in importlib.test.source.test_abc_loader that were masking
1069 the proper exceptions that should be raised for missing or improper code
1070 object bytecode.
1071
Brett Cannonb49c70c2009-07-15 04:08:33 +00001072- Removed importlib's custom test discovery code and switched to

1208Core and Builtins
1209-----------------
1210
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00001211- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
1212 of the command line.
1213
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00001214- Issue #6012: Add cleanup support to O& argument parsing.
1215
Eric Smith41669ca2009-05-23 14:23:22 +00001216- Issue #6089: Fixed str.format with certain invalid field specifiers
1217 that would raise SystemError.
1218
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001219- Issue #5982: staticmethod and classmethod now expose the wrapped
1220 function with __func__.
1221
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001222- Added support for multiple context managers in the same with-statement.
1223 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00001224
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001225- Issue #5829: complex("1e500") no longer raises OverflowError. This
1226 makes it consistent with float("1e500") and interpretation of real
1227 and imaginary literals.
1228
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001229- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1230
R. David Murraydd226ea2009-05-13 12:27:21 +00001231- Issue #5994: the marshal module now has docstrings.
1232
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001233- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1234 (1) inf and nan strings with trailing whitespace were incorrectly
1235 rejected; (2) parsing of strings representing infinities and nans
1236 was locale aware; and (3) the interpretation of fromhex('-nan')
1237 didn't match that of float('-nan').
1238
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001239Library
1240-------
1241
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00001242- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
1243
R. David Murrayfb123912009-05-28 18:19:00 +00001244- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
1245
R. David Murray1f1b9d32009-05-27 20:56:59 +00001246- Issue #6121: pydoc now ignores leading and trailing spaces in the
1247 argument to the 'help' function.
1248
Georg Brandlfaf41492009-05-26 18:31:11 +00001249- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1250 arguments for strings with a space in them.
1251
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001252- collections.namedtuple() was not working with the following field
1253 names: cls, self, tuple, itemgetter, and property.
1254
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001255- In unittest, using a skipping decorator on a class is now equivalent to
1256 skipping every test on the class. The ClassTestSuite class has been removed.
1257
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001258- Issue #6050: Don't fail extracting a directory from a zipfile if
1259 the directory already exists.
1260
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001261- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1262 than an int, which makes some operations possible under 64-bit Linux (e.g.
1263 DN_MULTISHOT with F_NOTIFY).
1264
Antoine Pitrou716c4442009-05-23 19:04:03 +00001265- Issue #5761: Add the name of the underlying file to the repr() of various
1266 IO objects.
1267
R. David Murraycaa27b72009-05-23 18:49:56 +00001268- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1269 by Musashi Tamura, tests by Marcin Bachry.
1270
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001271- Issue #1983: Fix functions taking or returning a process identifier to use
1272 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1273 a process identifier type wider than the standard C integer type.
1274
R. David Murray87e20742009-05-23 01:30:26 +00001275- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
1276 Patch by Farhan Ahmad, test by Marcin Bachry.
1277
Antoine Pitrou6e610062009-05-15 17:04:50 +00001278- Issue #2116: Weak references and weak dictionaries now support copy()ing and
1279 deepcopy()ing.
1280
Antoine Pitrouc1d09362009-05-15 12:15:51 +00001281- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.
1282
Antoine Pitrou37d1c182009-05-14 21:54:00 +00001283- Issue #5918: Fix a crash in the parser module.
1284
Antoine Pitrou2ca24f02009-05-14 21:30:46 +00001285- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
1286
Antoine Pitroue4501852009-05-14 18:55:55 +00001287- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1288 library. This means, for example, that opening an UTF-16 text file in
1289 append mode doesn't add a BOM at the end of the file if the file isn't
1290 empty.
1291
R. David Murray74b89242009-05-13 17:33:03 +00001292- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1293 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1294 corrects a pydoc regression.
1295
R. David Murray99352742009-05-07 18:24:38 +00001296- Issue 5955: aifc's close method did not close the file it wrapped,
1297 now it does. This also means getfp method now returns the real fp.
1298
Benjamin Peterson932073a2009-05-23 16:14:33 +00001299Installation
1300------------
1301
1302- Issue #6047: fullinstall has been removed because Python 3's executable will
1303 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001304
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00001305- Lib/smtpd.py is no longer installed as a script.

Martin v. Löwis1b01ccd2009-05-30 06:13:40 +00001311
Martin v. Löwise23c8682009-05-29 16:01:34 +00001312- Issue #4873: Fix resource leaks in error cases of pwd and grp.
1313
Martin v. Löwisdb1c3992009-05-23 10:38:26 +00001314- Issue #6093: Fix off-by-one error in locale.strxfrm.
1315
Benjamin Peterson744af442009-05-23 18:51:49 +00001316- The _functools and _locale modules are now built into the libpython shared
1317 library instead of as extension modules.
Benjamin Peterson3dc22e82009-05-23 17:09:43 +00001318
Antoine Pitrou20327222009-05-24 20:39:11 +00001319Build
1320-----
1321
1322- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file
1323 and a python3.pc symlink in the $(LIBDIR)/pkgconfig directory. Patch by
1324 Clinton Roy.
1325
Brett Cannon1262e7c2009-05-11 01:47:11 +00001326Tests
1327-----
1328
1329- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
1330 tests on darwin even when the OS was installed on a case-sensitive
1331 filesystem. Also fixed tests that should not be run when
1332 sys.dont_write_bytecode is true.
1333
1334
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001335What's New in Python 3.1 beta 1?
1336================================
1337
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001338*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001339
1340Core and Builtins
1341-----------------
1342
Mark Dickinson865e01a2009-05-07 16:37:01 +00001343- Issue #5914: Add new C API function PyOS_string_to_double, and
1344 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1345
Eric Smith741191f2009-05-06 13:08:15 +00001346- Issue #3382: float.__format__, complex.__format__, and %-formatting
1347 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1348 affects nan -> NAN and inf -> INF.
1349
Mark Hammond5a607a32009-05-06 08:04:54 +00001350- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1351 in all operations, including splitdrive, split, etc. splitunc() now issues
1352 a PendingDeprecation warning.
1353
Eric Smith63376222009-05-05 14:04:18 +00001354- Issue #5920: For float.__format__, change the behavior with the
1355 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1356 to be like 'g' but with at least one decimal point and with a
1357 default precision of 12. Previously, the behavior the same but with
1358 a default precision of 6. This more closely matches str(), and
1359 reduces surprises when adding alignment flags to the empty
1360 presentation type. This also affects the new complex.__format__ in
1361 the same way.
1362
Martin v. Löwis011e8422009-05-05 04:43:17 +00001363- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1364
R. David Murrayb18500d2009-05-04 22:59:07 +00001365- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1366 shadowed by classtype's, even if it was None. property now
1367 inserts the __doc__ into the subclass instance __dict__.
1368
Antoine Pitrou244651a2009-05-04 18:56:13 +00001369- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1370 sequences. Patch by Nick Barnes and Victor Stinner.
1371
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001372- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001373
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001374- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1375 received a new method, detach(). detach() disconnects the underlying stream
1376 from the buffer or text IO and returns it.
1377
Mark Dickinson33841c32009-05-01 15:37:04 +00001378- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1379 floats with absolute value over 1e50. Also remove length
1380 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1381 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001382
Eric Smith741191f2009-05-06 13:08:15 +00001383- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001384 format(complex(1, 2./3), '.5') now produces a sensible result.
1385
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001386- Issue #5864: Fix empty format code formatting for floats so that it
1387 never gives more than the requested number of significant digits.
1388
Eric Smith6dc46f52009-04-27 20:39:49 +00001389- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1390 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1391
Eric Smithcc32a112009-04-26 21:35:14 +00001392- Issue #5835: Deprecate PyOS_ascii_formatd.
1393
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001394- Issue #4971: Fix titlecase for characters that are their own
1395 titlecase, but not their own uppercase.
1396
Benjamin Peterson193152c2009-04-25 01:08:45 +00001397- Issue #5283: Setting __class__ in __del__ caused a segfault.
1398
Mark Dickinsonad476da2009-04-23 19:14:16 +00001399- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1400 z involves nans, infs or negative zeros.
1401
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001402- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001403
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001404- Issue #1869 (and many duplicates): make round(x, n) correctly
1405 rounded for a float x, by using the decimal <-> binary conversions
1406 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1407 consistently agrees with format(x, '.2f').
1408
Benjamin Petersonae937c02009-04-18 20:54:08 +00001409- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1410 some builtin types.
1411
Eric Smith0923d1d2009-04-16 20:16:10 +00001412- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1413
Eric Smith35e84722009-04-16 20:21:28 +00001414- Issue #5515: str.format() type 'n' combined with commas and leading
1415 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001416
1417- Implement PEP 378, Format Specifier for Thousands Separator, for
1418 floats.
1419
Mark Dickinson3370cce2009-04-17 22:40:53 +00001420- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001421 1e11, not 1e12. This avoids printing 13 significant digits in
1422 situations where only 12 of them are correct. Example problem
1423 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1424 long time.)
1425
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001426- Issue #1580: On most platforms, use a 'short' float repr: for a
1427 finite float x, repr(x) now outputs a string based on the shortest
1428 sequence of decimal digits that rounds to x. Previous behaviour was
1429 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001430 Another minor difference is that the new repr switches to
1431 exponential notation at 1e16 instead of the previous 1e17; this
1432 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001433
1434 There's a new sys attribute sys.float_repr_style, which takes
1435 the value 'short' to indicate that we're using short float repr,
1436 and 'legacy' if the short float repr isn't available for one
1437 reason or another.
1438
1439 The float repr change involves incorporating David Gay's 'perfect
1440 rounding' code into the Python core (it's in Python/dtoa.c). As a
1441 secondary consequence, all string-to-float and float-to-string
1442 conversions (including all float formatting operations) will be
1443 correctly rounded on these platforms.
1444
1445 See issue 1580 discussions for details of platforms for which
1446 this change does not apply.
1447
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001448- Issue #5759: float() didn't call __float__ on str subclasses.
1449
Georg Brandlabc38772009-04-12 15:51:51 +00001450- The string.maketrans() function is deprecated; there is a new static method
1451 maketrans() on the bytes and bytearray classes. This removes confusion about
1452 the types string.maketrans() is supposed to work with, and mirrors the
1453 methods available on the str class.
1454
R. David Murraydc6da8a2009-04-09 22:16:43 +00001455- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1456 its clarity and its speed.
1457
Matthias Klose091c7b12009-04-07 13:24:27 +00001458- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1459 to avoid compiler warnings.
1460
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001461- Issue #3739: The unicode-internal encoder now reports the number of characters
1462 consumed like any other encoder (instead of the number of bytes).

1477
Vinay Sajipaffbd872009-06-11 10:11:47 +00001478- Issue #5940: distutils.command.build_clib.check_library_list was not doing
Tarek Ziadédd9f65f2009-05-06 07:26:24 +00001479 the right type checkings anymore.

1796
Antoine Pitrouab868312009-01-10 15:40:25 +00001797- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1798 common cases are optimized thanks to a dedicated fast path and a moderate
1799 amount of loop unrolling.
1800
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001801- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1802 collecting the oldest generation) so that allocating lots of objects without
1803 destroying them does not show quadratic performance. Based on a proposal by
1804 Martin von Löwis at
1805 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1806
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001807- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001808 having been closed (for instance, a read() call could return some
1809 previously buffered data). Patch by Dmitry Vasiliev.
1810
Antoine Pitrou05608432009-01-09 18:53:14 +00001811- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1812 flag to work properly. Furthermore, when specifying -u, the text stdout
1813 and stderr streams have line-by-line buffering enabled (the default being
1814 to buffer arbitrary chunks of data).
1815
Raymond Hettinger35631532009-01-09 03:58:09 +00001816- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1817 instead of ints (reducing its size from 4 to 8 times thereby reducing
1818 Python's overall memory).
1819
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001820- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1821 an existing .py counterpart, override the co_filename attributes of all
1822 code objects if the original filename is obsolete (which can happen if the
1823 file has been renamed, moved, or if it is accessed through different paths).
1824 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1825
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001826- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1827 one byte. Also fixes the meaning of len() so that it returns the number of
1828 items, rather than the size in bytes.
1829
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001830- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001832- Issue #4747: When the terminal does not use utf-8, executing a script with
1833 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1834

1839 did not get collected.
1840
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001841- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1842 where the tp_hash and tp_dict slots are both NULL.
1843
Georg Brandlccc47b62008-12-28 11:44:14 +00001844- Issue #4759: None is now allowed as the first argument of
1845 bytearray.translate(). It was always allowed for bytes.translate().
1846
Skip Montanaro80072cb2008-12-23 03:51:14 +00001847- Added test case to ensure attempts to read from a file opened for writing
1848 fail.
1849

1854
Antoine Pitrou621601a2008-12-17 23:18:19 +00001855- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1857 unreachable. Original patch by Neil Schemenauer.
1858

Mark Dickinsonda2706b2008-12-11 18:03:03 +00001861- Issue #2173: When getting device encoding, check that return value of
1862 nl_langinfo is not the empty string. This was causing silent build
1863 failures on OS X.
1864
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001865- Issue #4597: Fixed several opcodes that weren't always propagating
1866 exceptions.
1867
1868- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001869 context manager returns a value that cannot be converted to a bool.
1870
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001871- Issue #4445: Replace "sizeof(PyBytesObject)" with
1872 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1873 bytes instances. On a typical machine this saves 3 bytes of memory
1874 (on average) per allocation of a bytes instance.
1875
Christian Heimesa872de52008-12-05 08:26:55 +00001876- Issue #4533: File read operation was dreadfully slow due to a slowly
1877 growing read buffer. Fixed by using the same growth rate algorithm as
1878 Python 2.x.
1879
Antoine Pitrou5504e892008-12-06 21:27:53 +00001880- Issue #4509: Various issues surrounding resize of bytearray objects to
1881 which there are buffer exports (e.g. memoryview instances).
1882
Georg Brandlf9734072008-12-07 15:30:06 +00001883- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1884 method on file objects with closefd=False. The file descriptor is still
1885 kept open but the file object behaves like a closed file. The ``FileIO``
1886 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001887
Antoine Pitroubc420402008-12-07 20:14:49 +00001888- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1894
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001895- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1896 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1897 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1898 of using the replace error handler in PyUnicode_DecodeUTF8().

2219 do an explicit seek to the end of file (so that e.g. tell() returns the
