Mark Dickinson3318d292010-04-06 16:53:17 +000015- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
16 on 64-bit machines. The shift count for either left or right shift is
17 permitted to be up to sys.maxsize.
18
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000019- Ensure that tokenization of identifiers is not affected by locale.

34 PyMemberDefs could produce an internal error; raise TypeError instead.
35
Mark Dickinsonf673f0c2010-03-13 09:48:39 +000036- Issue #7845: Rich comparison methods on the complex type now return
37 NotImplemented rather than raising a TypeError when comparing with an
38 incompatible type; this allows user-defined classes to implement their own
39 comparisons with complex.
40
Victor Stinner52f6dd72010-03-12 14:45:56 +000041- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
42 (SIGINT). If an error occurs while importing the site module, the error is
43 printed and Python exits. Initialize the GIL before importing the site
44 module.
45
Benjamin Petersonae5f2f42010-03-07 17:10:51 +000046- Issue #7173: Generator finalization could invalidate sys.exc_info().

75 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
76
Mark Dickinsonbc099642010-01-29 17:27:24 +000077- Issue #7788: Fix an interpreter crash produced by deleting a list
78 slice with very large step value.
79
Eric Smithf7bb5782010-01-27 00:44:57 +000080- Issue #7766: Change sys.getwindowsversion() return value to a named
81 tuple and add the additional members returned in an OSVERSIONINFOEX
82 structure. The new members are service_pack_major, service_pack_minor,
83 suite_mask, and product_type.
84
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000085- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
86 could crash in many places because of the PyByteArray_AS_STRING() macro
87 returning NULL. The macro now returns a statically allocated empty
88 string instead.
89
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000090- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
91 where the right hand operand is a set of constants, by turning the set into
92 a frozenset and pre-building it as a constant. The comparison operation
93 is made against the constant instead of building a new set each time it is
94 executed (a similar optimization already existed which turned a list of
95 constants into a pre-built tuple). Patch and additional tests by Dave
96 Malcolm.
97
Antoine Pitrouf2c54842010-01-13 08:07:53 +000098- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
99 methods of bytes, bytearray and unicode objects by using a common
100 implementation based on stringlib's fast search. Patch by Florent Xicluna.

103 alpha 2, including: (1) a serious 'wrong output' bug that could
104 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
105 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000106 strings corresponding to subnormal values, (3) a memory leak for
107 some values large enough to cause overflow, and (4) a number of
108 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000109
Benjamin Petersonaea44282010-01-04 01:10:28 +0000110- The __complex__ method is now looked up on the class of instances to make it

120 negative zero) in ** operator. The behaviour now conforms to that
121 described in C99 Annex F.
122
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000123- Issue #1811: improve accuracy and cross-platform consistency for
124 true division of integers: the result of a/b is now correctly
125 rounded for ints a and b (at least on IEEE 754 platforms), and in
126 particular does not depend on the internal representation of an int.
127
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000128- Issue #6834: replace the implementation for the 'python' and 'pythonw'
129 executables on OSX.
130
131 These executables now work properly with the arch(1) command:
132 ``arch -ppc python`` will start a universal binary version of python
133 in PPC mode (unlike previous releases).
134
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000135- Issue #7466: segmentation fault when the garbage collector is called

151
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000152- Issue #7298: fixes for range and reversed(range(...)). Iteration
153 over range(a, b, c) incorrectly gave an empty iterator when a, b and
154 c fit in C long but the length of the range did not. Also fix
155 several cases where reversed(range(a, b, c)) gave wrong results, and
156 fix a refleak for reversed(range(a, b, c)) with large arguments.

Mark Dickinson089b00c2010-04-03 15:51:03 +0000316- Issue #8257: The Decimal construct now accepts a float instance
317 directly, converting that float to a Decimal of equal value:
318
319 >>> Decimal(1.1)
320 Decimal('1.100000000000000088817841970012523233890533447265625')
321
Mark Dickinson98127c32010-04-03 11:18:52 +0000322- Issue #8294: The Fraction constructor now accepts Decimal and float
323 instances directly.
324
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000325- Issue #7279: Comparisons involving a Decimal signaling NaN now
326 signal InvalidOperation instead of returning False. (Comparisons
327 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
328 are now hashable; Decimal signaling NaNs remain unhashable.
329
330- Issue #2531: Comparison operations between floats and Decimal
331 instances now return a result based on the numeric values of the
332 operands; previously they returned an arbitrary result based on
333 the relative ordering of id(float) and id(Decimal).
334
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000335- Added a subtract() method to collections.Counter().
336
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000337- Issue #8233: When run as a script, py_compile.py optionally takes a single
338 argument `-` which tells it to read files to compile from stdin. Each line
339 is read on demand and the named file is compiled immediately. (Original
340 patch by Piotr Ożarowski).
341
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000342- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
343 form feed (0x0C) are now considered linebreaks, as specified in Unicode
344 Standard Annex #14. See issue #7643.
345 http://www.unicode.org/reports/tr14/
346
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000347- Comparisons using one of <, <=, >, >= between a complex instance and
348 a Fractions instance now raise TypeError instead of returning
349 True/False. This makes Fraction <=> complex comparisons consistent with
350 int <=> complex, float <=> complex, and complex <=> complex comparisons.
351
Antoine Pitrou39b35432010-03-23 00:25:54 +0000352- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
353 some methods (such as oss_mixer_device.fileno()) were not available.
354 Initial patch by Bertrand Janin.
355
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000356- Issue #8205: Remove the "Modules" directory from sys.path when Python is
357 running from the build directory (POSIX only).
358
Antoine Pitrou910bd512010-03-22 20:11:09 +0000359- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
360 didn't support chflags() (for example ZFS under FreeBSD). The error is
361 now silenced.
362
R. David Murrayca2edce2010-03-22 17:48:48 +0000363- Issue #7860: platform.uname now reports the correct 'machine' type
364 when Python is running in WOW64 mode on 64 bit Windows.
365
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000366- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
367 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
368 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000369
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000370- Issue #4282: Fix the main function of the profile module for a non-ASCII
371 script, open the file in binary mode and not in text mode with the default
372 (utf8) encoding.
373
Florent Xicluna54467e02010-03-21 12:29:50 +0000374- Issue #8179: Fix macpath.realpath() on a non-existing path.
375
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000376- Issue #8024: Update the Unicode database to 5.2.
377
Benjamin Peterson00888932010-03-18 22:37:38 +0000378- Issue #8168: py_compile now handles files with utf-8 BOMS.
379
Benjamin Peterson689a5582010-03-18 22:29:52 +0000380- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
381 detected.
382
Martin v. Löwis4b003072010-03-16 13:19:21 +0000383- Issue #6716/2: Backslash-replace error output in compilall.
384
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000385- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
386 with Tcl/Tk-8.5.
387
Matthias Klosec33b9022010-03-16 00:36:26 +0000388- Issue #8140: extend compileall to compile single files. Add -i option.
389
Matthias Klose82f60912010-03-15 13:46:04 +0000390- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
391 the locale.
392
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000393- The internals of the subprocess module on POSIX systems have been replaced
394 by an extension module (_posixsubprocess) so that the fork()+exec() can be
395 done safely without the possibility of deadlock in multithreaded applications.
396
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000397- subprocess.Popen now has restore_signals and start_new_session features.
398 The default of restore_signals=True is a new behavior compared to earlier
399 Python versions. This means that signals such as SIGPIPE are not ignored
400 by default in subprocesses launched by Python (Issue #1652).
401
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000402- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
403 cElementTree module is updated too.

412 the replacement were all bytes. Patch by Antoine Pitrou.
413
Gerhard Häringf9cee222010-03-05 15:20:03 +0000414- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
415 bugs and allows loading SQLite extensions from shared libraries.
416
Ezio Melottida227042010-03-14 11:51:00 +0000417- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public

Florent Xiclunac279ebf2010-02-27 11:31:21 +0000431- Issue #691291: codecs.open() should not convert end of lines on reading and
432 writing.
433

462 exception of canonical and is_canonical) now accept instances of int
463 and long wherever a Decimal instance is accepted, and implicitly
464 convert that argument to Decimal. Previously only some arguments
465 were converted.
466
R. David Murray1f449142010-02-11 00:15:05 +0000467- Issue #7835: shelve should no longer produce mysterious warnings during
468 interpreter shutdown.
469
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000470- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
471 in XML processing instructions and comments. These raw characters are
472 allowed by the XML specification, and are necessary when outputting e.g.
473 PHP code in a processing instruction. Patch by Neil Muller.

485 type is specified. Patch by Brian Curtin.
486
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000487- Issue #6939: Fix file I/O objects in the `io` module to keep the original
488 file position when calling `truncate()`. It would previously change the
489 file position to the given argument, which goes against the tradition of
490 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
491
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000492- Issue #7610: Reworked implementation of the internal
493 :class:`zipfile.ZipExtFile` class used to represent files stored inside
494 an archive. The new implementation is significantly faster and can
495 be wrapped in a :class:`io.BufferedReader` object for more speedups.
496 It also solves an issue where interleaved calls to `read()` and
497 `readline()` give wrong results. Patch by Nir Aides.
498
Jesse Noller1f0b6582010-01-27 03:36:01 +0000499- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

501 the worker before that worker is terminated, and a new one created to
502 replace it.
503
Benjamin Petersond6326642010-01-27 02:25:58 +0000504- Issue #7792: Registering non-classes to ABCs raised an obscure error.

661 to execute file paths that refer to source or compiled Python files as well
662 as zipfiles, directories and other valid sys.path entries that contain a
663 __main__.py file. This allows applications that run other Python scripts to
664 support the same flexibility as the CPython command line itself.
665
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000666- Issue #7318: multiprocessing now uses a timeout when it fails to establish

683 default when instantiating a `threading.RLock` object. This makes
684 recursive locks as fast as regular non-recursive locks (previously,
685 they were slower by 10x to 15x).

701 a modification is done through it. This fixes inconsistencies and test
702 failures on systems with slightly bogus mtime behaviour.
703
Gregory P. Smith50467882009-11-01 18:42:17 +0000704- Issue #7246 & Issue #7208: getpass now properly flushes input before
705 reading from stdin so that existing input does not confuse it and
706 lead to incorrect entry or an IOError. It also properly flushes it
707 afterwards to avoid the terminal echoing the input afterwards on
708 OSes such as Solaris.

1093
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001094- Issue #7222: Make thread "reaping" more reliable so that reference
1095 leak-chasing test runs give sensible results. The previous method of
1096 reaping threads could return successfully while some Thread objects were
1097 still referenced. This also introduces a new private function:
1098 :func:`_thread._count()`.
1099
R. David Murray27144602009-10-19 15:26:16 +00001100- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1102
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001103- Issue #7055: test___all__ now greedily detects all modules which have an

1111
Brett Cannon3c273842009-07-20 00:14:29 +00001112- Fixed tests in importlib.test.source.test_abc_loader that were masking
1113 the proper exceptions that should be raised for missing or improper code

1201 are always None now.
1202
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00001203- Issue #6137: The pickle module now translates module names when loading
1204 or dumping pickles with a 2.x-compatible protocol, in order to make data
1205 sharing and migration easier. This behaviour can be disabled using the
1206 new `fix_imports` optional argument.

1254
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00001255- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
1256 of the command line.
1257
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00001258- Issue #6012: Add cleanup support to O& argument parsing.
1259
Eric Smith41669ca2009-05-23 14:23:22 +00001260- Issue #6089: Fixed str.format with certain invalid field specifiers
1261 that would raise SystemError.
1262
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001263- Issue #5982: staticmethod and classmethod now expose the wrapped
1264 function with __func__.
1265
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001266- Added support for multiple context managers in the same with-statement.
1267 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00001268
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001269- Issue #5829: complex("1e500") no longer raises OverflowError. This
1270 makes it consistent with float("1e500") and interpretation of real
1271 and imaginary literals.
1272
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001273- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1274
R. David Murraydd226ea2009-05-13 12:27:21 +00001275- Issue #5994: the marshal module now has docstrings.
1276
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001277- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1278 (1) inf and nan strings with trailing whitespace were incorrectly
1279 rejected; (2) parsing of strings representing infinities and nans
1280 was locale aware; and (3) the interpretation of fromhex('-nan')
1281 didn't match that of float('-nan').

1284-------
1285
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00001286- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
1287
R. David Murrayfb123912009-05-28 18:19:00 +00001288- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
1289
R. David Murray1f1b9d32009-05-27 20:56:59 +00001290- Issue #6121: pydoc now ignores leading and trailing spaces in the
1291 argument to the 'help' function.
1292
Georg Brandlfaf41492009-05-26 18:31:11 +00001293- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1294 arguments for strings with a space in them.
1295
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001296- collections.namedtuple() was not working with the following field
1297 names: cls, self, tuple, itemgetter, and property.
1298
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001299- In unittest, using a skipping decorator on a class is now equivalent to
1300 skipping every test on the class. The ClassTestSuite class has been removed.
1301
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001302- Issue #6050: Don't fail extracting a directory from a zipfile if
1303 the directory already exists.
1304
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001305- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1306 than an int, which makes some operations possible under 64-bit Linux (e.g.
1307 DN_MULTISHOT with F_NOTIFY).
1308
Antoine Pitrou716c4442009-05-23 19:04:03 +00001309- Issue #5761: Add the name of the underlying file to the repr() of various
1310 IO objects.

1313 by Musashi Tamura, tests by Marcin Bachry.
1314
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001315- Issue #1983: Fix functions taking or returning a process identifier to use
1316 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1317 a process identifier type wider than the standard C integer type.
1318
R. David Murray87e20742009-05-23 01:30:26 +00001319- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1330
Antoine Pitroue4501852009-05-14 18:55:55 +00001331- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1332 library. This means, for example, that opening an UTF-16 text file in
1333 append mode doesn't add a BOM at the end of the file if the file isn't
1334 empty.
1335
R. David Murray74b89242009-05-13 17:33:03 +00001336- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1337 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1338 corrects a pydoc regression.
1339
R. David Murray99352742009-05-07 18:24:38 +00001340- Issue 5955: aifc's close method did not close the file it wrapped,
1341 now it does. This also means getfp method now returns the real fp.
1342
Benjamin Peterson932073a2009-05-23 16:14:33 +00001343Installation
1344------------
1345

1359
Benjamin Peterson744af442009-05-23 18:51:49 +00001360- The _functools and _locale modules are now built into the libpython shared
1361 library instead of as extension modules.
Benjamin Peterson3dc22e82009-05-23 17:09:43 +00001362

1368 Clinton Roy.
1369
Brett Cannon1262e7c2009-05-11 01:47:11 +00001370Tests
1371-----
1372
1373- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
1374 tests on darwin even when the OS was installed on a case-sensitive
1375 filesystem. Also fixed tests that should not be run when
1376 sys.dont_write_bytecode is true.
1377
1378
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001379What's New in Python 3.1 beta 1?
1380================================
1381
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001382*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001383
1384Core and Builtins
1385-----------------
1386
Mark Dickinson865e01a2009-05-07 16:37:01 +00001387- Issue #5914: Add new C API function PyOS_string_to_double, and
1388 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1389
Eric Smith741191f2009-05-06 13:08:15 +00001390- Issue #3382: float.__format__, complex.__format__, and %-formatting
1391 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1392 affects nan -> NAN and inf -> INF.
1393
Mark Hammond5a607a32009-05-06 08:04:54 +00001394- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1395 in all operations, including splitdrive, split, etc. splitunc() now issues
1396 a PendingDeprecation warning.
1397
Eric Smith63376222009-05-05 14:04:18 +00001398- Issue #5920: For float.__format__, change the behavior with the
1399 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1400 to be like 'g' but with at least one decimal point and with a
1401 default precision of 12. Previously, the behavior the same but with
1402 a default precision of 6. This more closely matches str(), and
1403 reduces surprises when adding alignment flags to the empty
1404 presentation type. This also affects the new complex.__format__ in
1405 the same way.
1406
Martin v. Löwis011e8422009-05-05 04:43:17 +00001407- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1408
R. David Murrayb18500d2009-05-04 22:59:07 +00001409- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1410 shadowed by classtype's, even if it was None. property now
1411 inserts the __doc__ into the subclass instance __dict__.
1412
Antoine Pitrou244651a2009-05-04 18:56:13 +00001413- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1414 sequences. Patch by Nick Barnes and Victor Stinner.
1415
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001416- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001417
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001418- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1419 received a new method, detach(). detach() disconnects the underlying stream
1420 from the buffer or text IO and returns it.
1421
Mark Dickinson33841c32009-05-01 15:37:04 +00001422- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1423 floats with absolute value over 1e50. Also remove length
1424 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1425 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001426
Eric Smith741191f2009-05-06 13:08:15 +00001427- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001428 format(complex(1, 2./3), '.5') now produces a sensible result.
1429
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001430- Issue #5864: Fix empty format code formatting for floats so that it
1431 never gives more than the requested number of significant digits.
1432
Eric Smith6dc46f52009-04-27 20:39:49 +00001433- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1434 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1435
Eric Smithcc32a112009-04-26 21:35:14 +00001436- Issue #5835: Deprecate PyOS_ascii_formatd.
1437
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001438- Issue #4971: Fix titlecase for characters that are their own
1439 titlecase, but not their own uppercase.
1440
Benjamin Peterson193152c2009-04-25 01:08:45 +00001441- Issue #5283: Setting __class__ in __del__ caused a segfault.
1442
Mark Dickinsonad476da2009-04-23 19:14:16 +00001443- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1444 z involves nans, infs or negative zeros.
1445
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001446- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001447
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001448- Issue #1869 (and many duplicates): make round(x, n) correctly
1449 rounded for a float x, by using the decimal <-> binary conversions
1450 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1451 consistently agrees with format(x, '.2f').
1452
Benjamin Petersonae937c02009-04-18 20:54:08 +00001453- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1454 some builtin types.
1455
Eric Smith0923d1d2009-04-16 20:16:10 +00001456- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1457
Eric Smith35e84722009-04-16 20:21:28 +00001458- Issue #5515: str.format() type 'n' combined with commas and leading
1459 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001460
1461- Implement PEP 378, Format Specifier for Thousands Separator, for
1462 floats.
1463
Mark Dickinson3370cce2009-04-17 22:40:53 +00001464- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001465 1e11, not 1e12. This avoids printing 13 significant digits in
1466 situations where only 12 of them are correct. Example problem
1467 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1468 long time.)
1469
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001470- Issue #1580: On most platforms, use a 'short' float repr: for a
1471 finite float x, repr(x) now outputs a string based on the shortest
1472 sequence of decimal digits that rounds to x. Previous behaviour was
1473 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001474 Another minor difference is that the new repr switches to
1475 exponential notation at 1e16 instead of the previous 1e17; this
1476 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001477
1478 There's a new sys attribute sys.float_repr_style, which takes
1479 the value 'short' to indicate that we're using short float repr,
1480 and 'legacy' if the short float repr isn't available for one
1481 reason or another.
1482
1483 The float repr change involves incorporating David Gay's 'perfect
1484 rounding' code into the Python core (it's in Python/dtoa.c). As a
1485 secondary consequence, all string-to-float and float-to-string
1486 conversions (including all float formatting operations) will be
1487 correctly rounded on these platforms.
1488
1489 See issue 1580 discussions for details of platforms for which
1490 this change does not apply.
1491
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001492- Issue #5759: float() didn't call __float__ on str subclasses.
1493
Georg Brandlabc38772009-04-12 15:51:51 +00001494- The string.maketrans() function is deprecated; there is a new static method
1495 maketrans() on the bytes and bytearray classes. This removes confusion about

1796
Mark Dickinsonc008a172009-02-01 13:59:22 +00001797- Issue #1717: Removed builtin cmp() function, dropped tp_compare
1798 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00001799 the type definition cmpfunc. The tp_compare slot has been renamed
1800 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001802- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001803 were suppressing all exceptions. These include list() and bytearray().
1804
Mark Dickinson1124e712009-01-28 21:25:58 +00001805- Issue #4707: round(x, n) now returns an integer if x is an integer.
1806 Previously it returned a float.
1807
Antoine Pitroub52ec782009-01-25 16:34:23 +00001808- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1809 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1810 evaluation loop is compiled with a new dispatch mechanism which gives
1811 speedups of up to 20%, depending on the system, on various benchmarks.
1812
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001813- Issue #4874: Most builtin decoders now reject unicode input.

Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001820- Issue #4838: When a module is deallocated, free the memory backing the
1821 optional module state data.
1822
Mark Dickinson8055afd2009-01-17 10:04:45 +00001823- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1824 type to (void *).
1825
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001826- Issue #4935: The overflow checking code in the expandtabs() method common
1827 to str, bytes and bytearray could be optimized away by the compiler, letting
1828 the interpreter segfault instead of raising an error.
1829
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001830- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1831 __next__ method.
1832
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001833- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1834 function no longer attempt to call the __long__ slot to convert an object
1835 to an integer. Only the __int__ and __trunc__ slots are examined.

1840
Antoine Pitrouab868312009-01-10 15:40:25 +00001841- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1842 common cases are optimized thanks to a dedicated fast path and a moderate
1843 amount of loop unrolling.
1844
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001845- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1846 collecting the oldest generation) so that allocating lots of objects without
1847 destroying them does not show quadratic performance. Based on a proposal by
1848 Martin von Löwis at
1849 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1850
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001851- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001852 having been closed (for instance, a read() call could return some
1853 previously buffered data). Patch by Dmitry Vasiliev.
1854
Antoine Pitrou05608432009-01-09 18:53:14 +00001855- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1856 flag to work properly. Furthermore, when specifying -u, the text stdout
1857 and stderr streams have line-by-line buffering enabled (the default being
1858 to buffer arbitrary chunks of data).
1859
Raymond Hettinger35631532009-01-09 03:58:09 +00001860- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1861 instead of ints (reducing its size from 4 to 8 times thereby reducing
1862 Python's overall memory).
1863
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001864- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1865 an existing .py counterpart, override the co_filename attributes of all
1866 code objects if the original filename is obsolete (which can happen if the
1867 file has been renamed, moved, or if it is accessed through different paths).
1868 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1869
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001870- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1871 one byte. Also fixes the meaning of len() so that it returns the number of
1872 items, rather than the size in bytes.
1873
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001874- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1875
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001876- Issue #4747: When the terminal does not use utf-8, executing a script with
1877 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1878
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001879- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1883 did not get collected.
1884
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001885- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1886 where the tp_hash and tp_dict slots are both NULL.
1887
Georg Brandlccc47b62008-12-28 11:44:14 +00001888- Issue #4759: None is now allowed as the first argument of
1889 bytearray.translate(). It was always allowed for bytes.translate().
1890
Skip Montanaro80072cb2008-12-23 03:51:14 +00001891- Added test case to ensure attempts to read from a file opened for writing
1892 fail.

1898
Antoine Pitrou621601a2008-12-17 23:18:19 +00001899- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Mark Dickinsonda2706b2008-12-11 18:03:03 +00001905- Issue #2173: When getting device encoding, check that return value of
1906 nl_langinfo is not the empty string. This was causing silent build
1907 failures on OS X.
1908
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001909- Issue #4597: Fixed several opcodes that weren't always propagating
1910 exceptions.
1911
1912- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001913 context manager returns a value that cannot be converted to a bool.
1914
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001915- Issue #4445: Replace "sizeof(PyBytesObject)" with
1916 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1917 bytes instances. On a typical machine this saves 3 bytes of memory
1918 (on average) per allocation of a bytes instance.
1919
Christian Heimesa872de52008-12-05 08:26:55 +00001920- Issue #4533: File read operation was dreadfully slow due to a slowly
1921 growing read buffer. Fixed by using the same growth rate algorithm as
1922 Python 2.x.
1923
Antoine Pitrou5504e892008-12-06 21:27:53 +00001924- Issue #4509: Various issues surrounding resize of bytearray objects to
1925 which there are buffer exports (e.g. memoryview instances).
1926
Georg Brandlf9734072008-12-07 15:30:06 +00001927- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1928 method on file objects with closefd=False. The file descriptor is still
1929 kept open but the file object behaves like a closed file. The ``FileIO``
1930 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001939- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1940 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1941 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1942 of using the replace error handler in PyUnicode_DecodeUTF8().
