72
Mark Dickinsonbc099642010-01-29 17:27:24 +000073- Issue #7788: Fix an interpreter crash produced by deleting a list
74 slice with very large step value.
75
Eric Smithf7bb5782010-01-27 00:44:57 +000076- Issue #7766: Change sys.getwindowsversion() return value to a named
77 tuple and add the additional members returned in an OSVERSIONINFOEX
78 structure. The new members are service_pack_major, service_pack_minor,
79 suite_mask, and product_type.
80
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000081- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
82 could crash in many places because of the PyByteArray_AS_STRING() macro
83 returning NULL. The macro now returns a statically allocated empty
84 string instead.
85
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000086- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
87 where the right hand operand is a set of constants, by turning the set into
88 a frozenset and pre-building it as a constant. The comparison operation
89 is made against the constant instead of building a new set each time it is
90 executed (a similar optimization already existed which turned a list of
91 constants into a pre-built tuple). Patch and additional tests by Dave
92 Malcolm.
93
Antoine Pitrouf2c54842010-01-13 08:07:53 +000094- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

96 implementation based on stringlib's fast search. Patch by Florent Xicluna.
97
Mark Dickinson45b63652010-01-16 18:10:25 +000098- Issue #7632: Fix various str -> float conversion bugs present in 2.7
99 alpha 2, including: (1) a serious 'wrong output' bug that could
100 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
101 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000102 strings corresponding to subnormal values, (3) a memory leak for
103 some values large enough to cause overflow, and (4) a number of
104 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000105
Benjamin Petersonaea44282010-01-04 01:10:28 +0000106- The __complex__ method is now looked up on the class of instances to make it

116 negative zero) in ** operator. The behaviour now conforms to that
117 described in C99 Annex F.
118
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000119- Issue #1811: improve accuracy and cross-platform consistency for
120 true division of integers: the result of a/b is now correctly
121 rounded for ints a and b (at least on IEEE 754 platforms), and in
122 particular does not depend on the internal representation of an int.
123
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000124- Issue #6834: replace the implementation for the 'python' and 'pythonw'
125 executables on OSX.
126
127 These executables now work properly with the arch(1) command:
128 ``arch -ppc python`` will start a universal binary version of python
129 in PPC mode (unlike previous releases).
130
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000131- Issue #7466: segmentation fault when the garbage collector is called

147
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000148- Issue #7298: fixes for range and reversed(range(...)). Iteration
149 over range(a, b, c) incorrectly gave an empty iterator when a, b and
150 c fit in C long but the length of the range did not. Also fix
151 several cases where reversed(range(a, b, c)) gave wrong results, and
152 fix a refleak for reversed(range(a, b, c)) with large arguments.

316 signal InvalidOperation instead of returning False. (Comparisons
317 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
318 are now hashable; Decimal signaling NaNs remain unhashable.
319
320- Issue #2531: Comparison operations between floats and Decimal
321 instances now return a result based on the numeric values of the
322 operands; previously they returned an arbitrary result based on
323 the relative ordering of id(float) and id(Decimal).
324
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000325- Added a subtract() method to collections.Counter().
326
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000327- Issue #8233: When run as a script, py_compile.py optionally takes a single
328 argument `-` which tells it to read files to compile from stdin. Each line
329 is read on demand and the named file is compiled immediately. (Original
330 patch by Piotr Ożarowski).
331
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000332- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
333 form feed (0x0C) are now considered linebreaks, as specified in Unicode
334 Standard Annex #14. See issue #7643.
335 http://www.unicode.org/reports/tr14/
336
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000337- Comparisons using one of <, <=, >, >= between a complex instance and
338 a Fractions instance now raise TypeError instead of returning
339 True/False. This makes Fraction <=> complex comparisons consistent with
340 int <=> complex, float <=> complex, and complex <=> complex comparisons.
341
Antoine Pitrou39b35432010-03-23 00:25:54 +0000342- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
343 some methods (such as oss_mixer_device.fileno()) were not available.
344 Initial patch by Bertrand Janin.
345
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000346- Issue #8205: Remove the "Modules" directory from sys.path when Python is

348
Antoine Pitrou910bd512010-03-22 20:11:09 +0000349- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
350 didn't support chflags() (for example ZFS under FreeBSD). The error is
351 now silenced.
352
R. David Murrayca2edce2010-03-22 17:48:48 +0000353- Issue #7860: platform.uname now reports the correct 'machine' type
354 when Python is running in WOW64 mode on 64 bit Windows.
355
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000356- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
357 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
358 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000359

361 script, open the file in binary mode and not in text mode with the default
362 (utf8) encoding.
363

365
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000366- Issue #8024: Update the Unicode database to 5.2.
367
Benjamin Peterson00888932010-03-18 22:37:38 +0000368- Issue #8168: py_compile now handles files with utf-8 BOMS.
369
Benjamin Peterson689a5582010-03-18 22:29:52 +0000370- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
371 detected.
372
Martin v. Löwis4b003072010-03-16 13:19:21 +0000373- Issue #6716/2: Backslash-replace error output in compilall.
374
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000375- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
376 with Tcl/Tk-8.5.
377

381 the locale.
382
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000383- The internals of the subprocess module on POSIX systems have been replaced
384 by an extension module (_posixsubprocess) so that the fork()+exec() can be
385 done safely without the possibility of deadlock in multithreaded applications.
386
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000387- subprocess.Popen now has restore_signals and start_new_session features.
388 The default of restore_signals=True is a new behavior compared to earlier
389 Python versions. This means that signals such as SIGPIPE are not ignored
390 by default in subprocesses launched by Python (Issue #1652).
391
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000392- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

402 the replacement were all bytes. Patch by Antoine Pitrou.
403
Gerhard Häringf9cee222010-03-05 15:20:03 +0000404- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
405 bugs and allows loading SQLite extensions from shared libraries.
406

422 writing.
423

452 exception of canonical and is_canonical) now accept instances of int
453 and long wherever a Decimal instance is accepted, and implicitly
454 convert that argument to Decimal. Previously only some arguments
455 were converted.
456
R. David Murray1f449142010-02-11 00:15:05 +0000457- Issue #7835: shelve should no longer produce mysterious warnings during
458 interpreter shutdown.
459
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000460- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
461 in XML processing instructions and comments. These raw characters are
462 allowed by the XML specification, and are necessary when outputting e.g.
463 PHP code in a processing instruction. Patch by Neil Muller.

475 type is specified. Patch by Brian Curtin.
476

478 file position when calling `truncate()`. It would previously change the
479 file position to the given argument, which goes against the tradition of
480 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
481
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000482- Issue #7610: Reworked implementation of the internal
483 :class:`zipfile.ZipExtFile` class used to represent files stored inside
484 an archive. The new implementation is significantly faster and can
485 be wrapped in a :class:`io.BufferedReader` object for more speedups.
486 It also solves an issue where interleaved calls to `read()` and
487 `readline()` give wrong results. Patch by Nir Aides.
488
Jesse Noller1f0b6582010-01-27 03:36:01 +0000489- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

491 the worker before that worker is terminated, and a new one created to
492 replace it.
493

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

695 reading from stdin so that existing input does not confuse it and
696 lead to incorrect entry or an IOError. It also properly flushes it

698 OSes such as Solaris.

1062 a test fails. Can be combined with -j.
1063
Antoine Pitrou060cee22009-11-13 16:29:04 +00001064- Issue #6551: test_zipimport could import and then destroy some modules of

1075 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1076 between concurrent executions on the same system.
1077
Brett Cannon0ae45112009-11-05 01:17:22 +00001078- Issue #7248: In importlib.test.source.util a try/finally block did not make
1079 sure that some referenced objects actually were created in the block before
1080 calling methods on the object.
1081
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001082- Issue #7222: Make thread "reaping" more reliable so that reference
1083 leak-chasing test runs give sensible results. The previous method of
1084 reaping threads could return successfully while some Thread objects were
1085 still referenced. This also introduces a new private function:
1086 :func:`_thread._count()`.
1087
R. David Murray27144602009-10-19 15:26:16 +00001088- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1089 longer runs the risk of causing the worker thread to fail.
1090
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001091- Issue #7055: test___all__ now greedily detects all modules which have an
1092 __all__ attribute, rather than using a hardcoded and incomplete list.

1095 runtest_inner in regrtest, with warnings if the called test modifies them,
1096 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001097
Mark Dickinson2e304402009-10-04 18:43:54 +00001098- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1099
Brett Cannon3c273842009-07-20 00:14:29 +00001100- Fixed tests in importlib.test.source.test_abc_loader that were masking
1101 the proper exceptions that should be raised for missing or improper code
1102 object bytecode.
1103
Brett Cannonb49c70c2009-07-15 04:08:33 +00001104- Removed importlib's custom test discovery code and switched to

1250
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001251- Issue #5982: staticmethod and classmethod now expose the wrapped
1252 function with __func__.
1253
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001254- Added support for multiple context managers in the same with-statement.
1255 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001257- Issue #5829: complex("1e500") no longer raises OverflowError. This
1258 makes it consistent with float("1e500") and interpretation of real
1259 and imaginary literals.
1260
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001261- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1262
R. David Murraydd226ea2009-05-13 12:27:21 +00001263- Issue #5994: the marshal module now has docstrings.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001265- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1266 (1) inf and nan strings with trailing whitespace were incorrectly
1267 rejected; (2) parsing of strings representing infinities and nans
1268 was locale aware; and (3) the interpretation of fromhex('-nan')
1269 didn't match that of float('-nan').

1277
R. David Murray1f1b9d32009-05-27 20:56:59 +00001278- Issue #6121: pydoc now ignores leading and trailing spaces in the

1280
Georg Brandlfaf41492009-05-26 18:31:11 +00001281- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1282 arguments for strings with a space in them.
1283
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001284- collections.namedtuple() was not working with the following field
1285 names: cls, self, tuple, itemgetter, and property.
1286
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001287- In unittest, using a skipping decorator on a class is now equivalent to
1288 skipping every test on the class. The ClassTestSuite class has been removed.
1289
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001290- Issue #6050: Don't fail extracting a directory from a zipfile if
1291 the directory already exists.
1292
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001293- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1294 than an int, which makes some operations possible under 64-bit Linux (e.g.
1295 DN_MULTISHOT with F_NOTIFY).
1296
Antoine Pitrou716c4442009-05-23 19:04:03 +00001297- Issue #5761: Add the name of the underlying file to the repr() of various

1302
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001303- Issue #1983: Fix functions taking or returning a process identifier to use
1304 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1305 a process identifier type wider than the standard C integer type.
1306
R. David Murray87e20742009-05-23 01:30:26 +00001307- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1318
Antoine Pitroue4501852009-05-14 18:55:55 +00001319- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1320 library. This means, for example, that opening an UTF-16 text file in
1321 append mode doesn't add a BOM at the end of the file if the file isn't
1322 empty.
1323
R. David Murray74b89242009-05-13 17:33:03 +00001324- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1325 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1326 corrects a pydoc regression.
1327
R. David Murray99352742009-05-07 18:24:38 +00001328- Issue 5955: aifc's close method did not close the file it wrapped,

1372Core and Builtins
1373-----------------
1374
Mark Dickinson865e01a2009-05-07 16:37:01 +00001375- Issue #5914: Add new C API function PyOS_string_to_double, and
1376 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1377
Eric Smith741191f2009-05-06 13:08:15 +00001378- Issue #3382: float.__format__, complex.__format__, and %-formatting
1379 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1380 affects nan -> NAN and inf -> INF.
1381
Mark Hammond5a607a32009-05-06 08:04:54 +00001382- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1383 in all operations, including splitdrive, split, etc. splitunc() now issues
1384 a PendingDeprecation warning.
1385
Eric Smith63376222009-05-05 14:04:18 +00001386- Issue #5920: For float.__format__, change the behavior with the
1387 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1388 to be like 'g' but with at least one decimal point and with a
1389 default precision of 12. Previously, the behavior the same but with
1390 a default precision of 6. This more closely matches str(), and
1391 reduces surprises when adding alignment flags to the empty
1392 presentation type. This also affects the new complex.__format__ in
1393 the same way.
1394
Martin v. Löwis011e8422009-05-05 04:43:17 +00001395- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1396
R. David Murrayb18500d2009-05-04 22:59:07 +00001397- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1398 shadowed by classtype's, even if it was None. property now
1399 inserts the __doc__ into the subclass instance __dict__.
1400
Antoine Pitrou244651a2009-05-04 18:56:13 +00001401- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1402 sequences. Patch by Nick Barnes and Victor Stinner.
1403
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001404- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001405
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001406- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1407 received a new method, detach(). detach() disconnects the underlying stream
1408 from the buffer or text IO and returns it.
1409
Mark Dickinson33841c32009-05-01 15:37:04 +00001410- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1411 floats with absolute value over 1e50. Also remove length
1412 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1413 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001414
Eric Smith741191f2009-05-06 13:08:15 +00001415- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001416 format(complex(1, 2./3), '.5') now produces a sensible result.
1417
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001418- Issue #5864: Fix empty format code formatting for floats so that it
1419 never gives more than the requested number of significant digits.
1420
Eric Smith6dc46f52009-04-27 20:39:49 +00001421- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1422 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1423
Eric Smithcc32a112009-04-26 21:35:14 +00001424- Issue #5835: Deprecate PyOS_ascii_formatd.
1425
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001426- Issue #4971: Fix titlecase for characters that are their own
1427 titlecase, but not their own uppercase.
1428
Benjamin Peterson193152c2009-04-25 01:08:45 +00001429- Issue #5283: Setting __class__ in __del__ caused a segfault.
1430
Mark Dickinsonad476da2009-04-23 19:14:16 +00001431- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1432 z involves nans, infs or negative zeros.
1433
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001434- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001435
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001436- Issue #1869 (and many duplicates): make round(x, n) correctly
1437 rounded for a float x, by using the decimal <-> binary conversions
1438 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1439 consistently agrees with format(x, '.2f').
1440
Benjamin Petersonae937c02009-04-18 20:54:08 +00001441- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1442 some builtin types.
1443
Eric Smith0923d1d2009-04-16 20:16:10 +00001444- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1445
Eric Smith35e84722009-04-16 20:21:28 +00001446- Issue #5515: str.format() type 'n' combined with commas and leading
1447 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001448
1449- Implement PEP 378, Format Specifier for Thousands Separator, for
1450 floats.
1451
Mark Dickinson3370cce2009-04-17 22:40:53 +00001452- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001453 1e11, not 1e12. This avoids printing 13 significant digits in
1454 situations where only 12 of them are correct. Example problem
1455 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1456 long time.)
1457
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001458- Issue #1580: On most platforms, use a 'short' float repr: for a
1459 finite float x, repr(x) now outputs a string based on the shortest
1460 sequence of decimal digits that rounds to x. Previous behaviour was
1461 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001462 Another minor difference is that the new repr switches to
1463 exponential notation at 1e16 instead of the previous 1e17; this
1464 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001465
1466 There's a new sys attribute sys.float_repr_style, which takes
1467 the value 'short' to indicate that we're using short float repr,
1468 and 'legacy' if the short float repr isn't available for one
1469 reason or another.
1470
1471 The float repr change involves incorporating David Gay's 'perfect
1472 rounding' code into the Python core (it's in Python/dtoa.c). As a
1473 secondary consequence, all string-to-float and float-to-string
1474 conversions (including all float formatting operations) will be
1475 correctly rounded on these platforms.
1476
1477 See issue 1580 discussions for details of platforms for which
1478 this change does not apply.
1479
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001480- Issue #5759: float() didn't call __float__ on str subclasses.
1481
Georg Brandlabc38772009-04-12 15:51:51 +00001482- The string.maketrans() function is deprecated; there is a new static method
1483 maketrans() on the bytes and bytearray classes. This removes confusion about
1484 the types string.maketrans() is supposed to work with, and mirrors the
1485 methods available on the str class.
1486
R. David Murraydc6da8a2009-04-09 22:16:43 +00001487- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1488 its clarity and its speed.
1489
Matthias Klose091c7b12009-04-07 13:24:27 +00001490- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1491 to avoid compiler warnings.
1492
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001493- Issue #3739: The unicode-internal encoder now reports the number of characters
1494 consumed like any other encoder (instead of the number of bytes).

Antoine Pitroub52ec782009-01-25 16:34:23 +00001796- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1797 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1798 evaluation loop is compiled with a new dispatch mechanism which gives
1799 speedups of up to 20%, depending on the system, on various benchmarks.
1800
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001801- Issue #4874: Most builtin decoders now reject unicode input.

1807
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001808- Issue #4838: When a module is deallocated, free the memory backing the
1809 optional module state data.
1810
Mark Dickinson8055afd2009-01-17 10:04:45 +00001811- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1812 type to (void *).
1813
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001814- Issue #4935: The overflow checking code in the expandtabs() method common
1815 to str, bytes and bytearray could be optimized away by the compiler, letting
1816 the interpreter segfault instead of raising an error.
1817
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001818- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1819 __next__ method.
1820
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001821- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1822 function no longer attempt to call the __long__ slot to convert an object
1823 to an integer. Only the __int__ and __trunc__ slots are examined.

1828
Antoine Pitrouab868312009-01-10 15:40:25 +00001829- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1830 common cases are optimized thanks to a dedicated fast path and a moderate
1831 amount of loop unrolling.
1832
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001833- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1834 collecting the oldest generation) so that allocating lots of objects without
1835 destroying them does not show quadratic performance. Based on a proposal by
1836 Martin von Löwis at
1837 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1838
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001839- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001840 having been closed (for instance, a read() call could return some
1841 previously buffered data). Patch by Dmitry Vasiliev.
1842
Antoine Pitrou05608432009-01-09 18:53:14 +00001843- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1844 flag to work properly. Furthermore, when specifying -u, the text stdout
1845 and stderr streams have line-by-line buffering enabled (the default being
1846 to buffer arbitrary chunks of data).
1847
Raymond Hettinger35631532009-01-09 03:58:09 +00001848- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1849 instead of ints (reducing its size from 4 to 8 times thereby reducing
1850 Python's overall memory).
1851
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001852- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1853 an existing .py counterpart, override the co_filename attributes of all
1854 code objects if the original filename is obsolete (which can happen if the
1855 file has been renamed, moved, or if it is accessed through different paths).
1856 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1857
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001858- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1859 one byte. Also fixes the meaning of len() so that it returns the number of
1860 items, rather than the size in bytes.
1861
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001862- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1863
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001864- Issue #4747: When the terminal does not use utf-8, executing a script with
1865 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1866
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001867- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1871 did not get collected.
1872
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001873- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1874 where the tp_hash and tp_dict slots are both NULL.
1875
Georg Brandlccc47b62008-12-28 11:44:14 +00001876- Issue #4759: None is now allowed as the first argument of
1877 bytearray.translate(). It was always allowed for bytes.translate().
1878
Skip Montanaro80072cb2008-12-23 03:51:14 +00001879- Added test case to ensure attempts to read from a file opened for writing
1880 fail.

1886
Antoine Pitrou621601a2008-12-17 23:18:19 +00001887- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1889 unreachable. Original patch by Neil Schemenauer.
1890

1892
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001893- Issue #2173: When getting device encoding, check that return value of
1894 nl_langinfo is not the empty string. This was causing silent build
1895 failures on OS X.
1896
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001897- Issue #4597: Fixed several opcodes that weren't always propagating
1898 exceptions.
1899
1900- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001901 context manager returns a value that cannot be converted to a bool.
1902
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001903- Issue #4445: Replace "sizeof(PyBytesObject)" with
1904 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1905 bytes instances. On a typical machine this saves 3 bytes of memory
1906 (on average) per allocation of a bytes instance.
1907
Christian Heimesa872de52008-12-05 08:26:55 +00001908- Issue #4533: File read operation was dreadfully slow due to a slowly
1909 growing read buffer. Fixed by using the same growth rate algorithm as
1910 Python 2.x.
1911
Antoine Pitrou5504e892008-12-06 21:27:53 +00001912- Issue #4509: Various issues surrounding resize of bytearray objects to
1913 which there are buffer exports (e.g. memoryview instances).
1914
Georg Brandlf9734072008-12-07 15:30:06 +00001915- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1916 method on file objects with closefd=False. The file descriptor is still
1917 kept open but the file object behaves like a closed file. The ``FileIO``
1918 object also got a new readonly attribute ``closefd``.

1926
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001927- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1928 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1929 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1930 of using the replace error handler in PyUnicode_DecodeUTF8().
