102
Mark Dickinsonbc099642010-01-29 17:27:24 +0000103- Issue #7788: Fix an interpreter crash produced by deleting a list
104 slice with very large step value.
105
Eric Smithf7bb5782010-01-27 00:44:57 +0000106- Issue #7766: Change sys.getwindowsversion() return value to a named
107 tuple and add the additional members returned in an OSVERSIONINFOEX
108 structure. The new members are service_pack_major, service_pack_minor,
109 suite_mask, and product_type.
110
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000111- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
112 could crash in many places because of the PyByteArray_AS_STRING() macro
113 returning NULL. The macro now returns a statically allocated empty
114 string instead.
115
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000116- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
117 where the right hand operand is a set of constants, by turning the set into
118 a frozenset and pre-building it as a constant. The comparison operation
119 is made against the constant instead of building a new set each time it is
120 executed (a similar optimization already existed which turned a list of
121 constants into a pre-built tuple). Patch and additional tests by Dave
122 Malcolm.
123
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000124- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
125 methods of bytes, bytearray and unicode objects by using a common
126 implementation based on stringlib's fast search. Patch by Florent Xicluna.
127
Mark Dickinson45b63652010-01-16 18:10:25 +0000128- Issue #7632: Fix various str -> float conversion bugs present in 2.7
129 alpha 2, including: (1) a serious 'wrong output' bug that could
130 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
131 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000132 strings corresponding to subnormal values, (3) a memory leak for
133 some values large enough to cause overflow, and (4) a number of
134 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000135
Benjamin Petersonaea44282010-01-04 01:10:28 +0000136- The __complex__ method is now looked up on the class of instances to make it
137 consistent with other special methods.

146 negative zero) in ** operator. The behaviour now conforms to that
147 described in C99 Annex F.
148
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000149- Issue #1811: improve accuracy and cross-platform consistency for
150 true division of integers: the result of a/b is now correctly
151 rounded for ints a and b (at least on IEEE 754 platforms), and in
152 particular does not depend on the internal representation of an int.
153
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000154- Issue #6834: replace the implementation for the 'python' and 'pythonw'
155 executables on OSX.
156
157 These executables now work properly with the arch(1) command:
158 ``arch -ppc python`` will start a universal binary version of python
159 in PPC mode (unlike previous releases).
160
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000161- Issue #7466: segmentation fault when the garbage collector is called

177
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000178- Issue #7298: fixes for range and reversed(range(...)). Iteration
179 over range(a, b, c) incorrectly gave an empty iterator when a, b and
180 c fit in C long but the length of the range did not. Also fix
181 several cases where reversed(range(a, b, c)) gave wrong results, and
182 fix a refleak for reversed(range(a, b, c)) with large arguments.

Mark Dickinson6ce4a9a2009-11-16 17:00:11 +0000314 and PyErr_Format, on machines with HAVE_LONG_LONG defined.
315
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000316- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
317 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
318 should used for accessing the d_type and d_name members of structures
319 using PyDescr_COMMON.
320
321- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000322
Benjamin Peterson466a7822009-07-02 21:44:01 +0000323- The code flags for old __future__ features are now available again.
324
Alexandre Vassalotti7b82b402009-07-21 04:30:03 +0000325- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
326 PyCode_Addr2Line().
327
328- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
329 object at a specified file, function, and line number.
330
331- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
332 ``const char *`` as the string is stored beyond the call.
333
Benjamin Peterson05159c42009-12-03 03:01:27 +0000334- Issue #2422: When compiled with the ``--with-valgrind`` option, the
335 pymalloc allocator will be automatically disabled when running under
336 Valgrind. This gives improved memory leak detection when running
337 under Valgrind, while taking advantage of pymalloc at other times.

343
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000344- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
345 It should correctly return an empty response now.
346
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000347- Issue #8546: Reject None given as the buffering argument to _pyio.open.
348
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000349- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
350 Sridhar Ratnakumar.

353 and mappings.
354
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000355- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
356 where the method could block indefinitely if called just before the
357 event loop started running. This also fixes the occasional freezes
358 witnessed in test_httpservers.
359
Antoine Pitrou40f08742010-04-24 22:04:40 +0000360- Issue #8524: When creating an SSL socket, the timeout value of the
361 original socket wasn't retained (instead, a socket with a positive timeout
362 would be turned into a non-blocking SSL socket).
363
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000364- Issue #5103: SSL handshake would ignore the socket timeout and block
365 indefinitely if the other end didn't respond.
366
367- The do_handshake() method of SSL objects now adjusts the blocking mode of
368 the SSL structure if necessary (as other methods already do).
369
Victor Stinner13bb71c2010-04-23 21:41:56 +0000370- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
371 and bytes strings for environment keys and values
372
Victor Stinner4d078042010-04-23 19:28:32 +0000373- Issue #8467: Pure Python implementation of subprocess encodes the error

375 message
376
Victor Stinner349fd522010-04-23 10:56:17 +0000377- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
378
Sean Reifscheider13daf122010-04-23 09:29:52 +0000379- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
380 the string "python" as the *ident*. openlog() arguments are all optional
381 and keywords.
382
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000383- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
384 a non-infinite timeout. Also make that method friendlier with applications
385 wanting to continue using the socket in clear-text mode, by disabling
386 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
387
Antoine Pitrou7062db82010-04-22 13:30:10 +0000388- Issue #8496: make mailcap.lookup() always return a list, rather than an
389 iterator. Patch by Gregory Nofi.
390
Victor Stinner35466c52010-04-22 11:23:23 +0000391- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
392 collation name contains a surrogate character.
393
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000394- Issue #8484: Load all ciphers and digest algorithms when initializing
395 the _ssl extension, such that verification of some SSL certificates
396 doesn't fail because of an "unknown algorithm".
397
Tarek Ziadéfb437512010-04-20 08:57:33 +0000398- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
399
Tarek Ziadé5340db32010-04-19 22:30:51 +0000400- Issue #1540112: Now allowing the choice of a copy function in
401 shutil.copytree.
402
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000403- Issue #4814: timeout parameter is now applied also for connections resulting
404 from PORT/EPRT commands.
405
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000406- Issue #8463: added missing reference to bztar in shutil's documentation.
407
Ronald Oussoren84151202010-04-18 20:46:11 +0000408- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
409 (as long as the user didn't specify 'automatic proxy configuration').
410
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000411- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
412 code as stated in RFC-959 at chapter 5.4.
413
Victor Stinner738446f02010-04-18 00:00:44 +0000414- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
415 surrogates.
416
Antoine Pitrou0454af92010-04-17 23:51:58 +0000417- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000418 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

430 surrogates.
431
Senthil Kumaranad02d232010-04-16 03:02:13 +0000432- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
433 Locke and Hans Ulrich Niedermann.
434
R. David Murrayd48739f2010-04-14 18:59:18 +0000435- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
436
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000437- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
438 module now takes an optional timeout argument in seconds. Timeout support
439 relies on the system threading library, so as to avoid a semi-busy wait
440 loop.
441
Victor Stinner485fb562010-04-13 11:07:24 +0000442- Issue #8383: pickle and pickletools use surrogatepass error handler when
443 encoding unicode as utf8 to support lone surrogates and stay compatible with
444 Python 2.x and 3.0
445
R. David Murrayb2416e52010-04-12 16:58:02 +0000446- Issue #7585: difflib context and unified diffs now place a tab between
447 filename and date, conforming to the 'standards' they were originally
448 designed to follow. This improves compatibility with patch tools.
449
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000450- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
451 character sets will now consistently use a Content-Transfer-Encoding of
452 7bit rather than sometimes being marked as 8bit.
453
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000454- Issue #8375: test_distutils now checks if the temporary directory are still
455 present before it cleans them.
456
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000457- Issue #8374: Update the internal alias table in the :mod:`locale` module
458 to cover recent locale changes and additions.

Antoine Pitrou04f6a322010-04-05 21:40:07 +0000460- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
461 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
462 and `ssl.OPENSSL_VERSION_NUMBER`.
463
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000464- Add functools.total_ordering() and functools.cmp_to_key().
465
Mark Dickinson089b00c2010-04-03 15:51:03 +0000466- Issue #8257: The Decimal construct now accepts a float instance
467 directly, converting that float to a Decimal of equal value:
468
469 >>> Decimal(1.1)
470 Decimal('1.100000000000000088817841970012523233890533447265625')
471
Mark Dickinson98127c32010-04-03 11:18:52 +0000472- Issue #8294: The Fraction constructor now accepts Decimal and float
473 instances directly.
474
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000475- Issue #7279: Comparisons involving a Decimal signaling NaN now
476 signal InvalidOperation instead of returning False. (Comparisons
477 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
478 are now hashable; Decimal signaling NaNs remain unhashable.
479
480- Issue #2531: Comparison operations between floats and Decimal
481 instances now return a result based on the numeric values of the
482 operands; previously they returned an arbitrary result based on
483 the relative ordering of id(float) and id(Decimal).
484
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000485- Added a subtract() method to collections.Counter().
486
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000487- Issue #8233: When run as a script, py_compile.py optionally takes a single
488 argument `-` which tells it to read files to compile from stdin. Each line
489 is read on demand and the named file is compiled immediately. (Original
490 patch by Piotr Ożarowski).
491
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000492- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
493 form feed (0x0C) are now considered linebreaks, as specified in Unicode
494 Standard Annex #14. See issue #7643.
495 http://www.unicode.org/reports/tr14/
496
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000497- Comparisons using one of <, <=, >, >= between a complex instance and
498 a Fractions instance now raise TypeError instead of returning
499 True/False. This makes Fraction <=> complex comparisons consistent with
500 int <=> complex, float <=> complex, and complex <=> complex comparisons.
501
Antoine Pitrou39b35432010-03-23 00:25:54 +0000502- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
503 some methods (such as oss_mixer_device.fileno()) were not available.
504 Initial patch by Bertrand Janin.
505
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000506- Issue #8205: Remove the "Modules" directory from sys.path when Python is
507 running from the build directory (POSIX only).
508
Antoine Pitrou910bd512010-03-22 20:11:09 +0000509- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
510 didn't support chflags() (for example ZFS under FreeBSD). The error is
511 now silenced.
512
R. David Murrayca2edce2010-03-22 17:48:48 +0000513- Issue #7860: platform.uname now reports the correct 'machine' type
514 when Python is running in WOW64 mode on 64 bit Windows.
515
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000516- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
517 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
518 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000519
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000520- Issue #4282: Fix the main function of the profile module for a non-ASCII
521 script, open the file in binary mode and not in text mode with the default
522 (utf8) encoding.
523
Florent Xicluna54467e02010-03-21 12:29:50 +0000524- Issue #8179: Fix macpath.realpath() on a non-existing path.
525

529
Benjamin Peterson689a5582010-03-18 22:29:52 +0000530- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
531 detected.
532
Martin v. Löwis4b003072010-03-16 13:19:21 +0000533- Issue #6716/2: Backslash-replace error output in compilall.
534
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000535- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
536 with Tcl/Tk-8.5.
537
Matthias Klosec33b9022010-03-16 00:36:26 +0000538- Issue #8140: extend compileall to compile single files. Add -i option.

541 the locale.
542
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000543- The internals of the subprocess module on POSIX systems have been replaced
544 by an extension module (_posixsubprocess) so that the fork()+exec() can be
545 done safely without the possibility of deadlock in multithreaded applications.
546
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000547- subprocess.Popen now has restore_signals and start_new_session features.
548 The default of restore_signals=True is a new behavior compared to earlier
549 Python versions. This means that signals such as SIGPIPE are not ignored
550 by default in subprocesses launched by Python (Issue #1652).
551
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000552- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

562 the replacement were all bytes. Patch by Antoine Pitrou.
563
Gerhard Häringf9cee222010-03-05 15:20:03 +0000564- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure

596
Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +0000597- Issue #6666: fix bug in trace.py that applied the list of directories
598 to be ignored only to the first file. Noted by Bogdan Opanchuk.
599
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000600- Issue #7597: curses.use_env() can now be called before initscr().
601 Noted by Kan-Ru Chen.
602
Ezio Melotti19e4acf2010-02-22 15:59:01 +0000603- Issue #7310: fix the __repr__ of os.environ to show the environment variables.

609 bytecode file when it was less then 8 bytes.
610
Mark Dickinson84230a12010-02-18 14:49:50 +0000611- Issue #7633: In the decimal module, Context class methods (with the
612 exception of canonical and is_canonical) now accept instances of int
613 and long wherever a Decimal instance is accepted, and implicitly
614 convert that argument to Decimal. Previously only some arguments

618 interpreter shutdown.
619
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000620- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
621 in XML processing instructions and comments. These raw characters are
622 allowed by the XML specification, and are necessary when outputting e.g.
623 PHP code in a processing instruction. Patch by Neil Muller.

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

643 :class:`zipfile.ZipExtFile` class used to represent files stored inside
644 an archive. The new implementation is significantly faster and can
645 be wrapped in a :class:`io.BufferedReader` object for more speedups.
646 It also solves an issue where interleaved calls to `read()` and
647 `readline()` give wrong results. Patch by Nir Aides.
648
Jesse Noller1f0b6582010-01-27 03:36:01 +0000649- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000810- Issue #6816: runpy now provides a run_path function that allows Python code
811 to execute file paths that refer to source or compiled Python files as well
812 as zipfiles, directories and other valid sys.path entries that contain a

814 support the same flexibility as the CPython command line itself.
815
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000816- Issue #7318: multiprocessing now uses a timeout when it fails to establish

852 failures on systems with slightly bogus mtime behaviour.
853
Gregory P. Smith50467882009-11-01 18:42:17 +0000854- Issue #7246 & Issue #7208: getpass now properly flushes input before
855 reading from stdin so that existing input does not confuse it and

1225
Ezio Melotti184bdfb2010-02-18 09:37:05 +00001226- Issue #7712: test.support gained a new `temp_cwd` context manager which is

1248 user running the tests.
1249
R. David Murray35768ad2009-11-15 00:23:21 +00001250- Issue #7324: add a sanity check to regrtest argument parsing to

1254 a test fails. Can be combined with -j.
1255
Antoine Pitrou060cee22009-11-13 16:29:04 +00001256- Issue #6551: test_zipimport could import and then destroy some modules of
1257 the encodings package, which would make other tests fail further down
1258 the road because the internally cached encoders and decoders would point
1259 to empty global variables.
1260

1267 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1268 between concurrent executions on the same system.
1269
Brett Cannon0ae45112009-11-05 01:17:22 +00001270- Issue #7248: In importlib.test.source.util a try/finally block did not make
1271 sure that some referenced objects actually were created in the block before
1272 calling methods on the object.
1273
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001274- Issue #7222: Make thread "reaping" more reliable so that reference
1275 leak-chasing test runs give sensible results. The previous method of
1276 reaping threads could return successfully while some Thread objects were
1277 still referenced. This also introduces a new private function:
1278 :func:`_thread._count()`.
1279
R. David Murray27144602009-10-19 15:26:16 +00001280- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1281 longer runs the risk of causing the worker thread to fail.
1282
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001283- Issue #7055: test___all__ now greedily detects all modules which have an
1284 __all__ attribute, rather than using a hardcoded and incomplete list.
1285
R. David Murray0bc11ae2009-10-18 22:18:17 +00001286- Issue #7058: Added save/restore for things like sys.argv and cwd to
1287 runtest_inner in regrtest, with warnings if the called test modifies them,
1288 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001289
Mark Dickinson2e304402009-10-04 18:43:54 +00001290- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1291
Brett Cannon3c273842009-07-20 00:14:29 +00001292- Fixed tests in importlib.test.source.test_abc_loader that were masking
1293 the proper exceptions that should be raised for missing or improper code
1294 object bytecode.
1295
Brett Cannonb49c70c2009-07-15 04:08:33 +00001296- Removed importlib's custom test discovery code and switched to
1297 unittest.TestLoader.discover().

Antoine Pitroue4501852009-05-14 18:55:55 +00001511- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1512 library. This means, for example, that opening an UTF-16 text file in
1513 append mode doesn't add a BOM at the end of the file if the file isn't
1514 empty.

1518 corrects a pydoc regression.
1519
R. David Murray99352742009-05-07 18:24:38 +00001520- Issue 5955: aifc's close method did not close the file it wrapped,

1564Core and Builtins
1565-----------------
1566
Mark Dickinson865e01a2009-05-07 16:37:01 +00001567- Issue #5914: Add new C API function PyOS_string_to_double, and
1568 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1569
Eric Smith741191f2009-05-06 13:08:15 +00001570- Issue #3382: float.__format__, complex.__format__, and %-formatting
1571 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1572 affects nan -> NAN and inf -> INF.
1573
Mark Hammond5a607a32009-05-06 08:04:54 +00001574- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1575 in all operations, including splitdrive, split, etc. splitunc() now issues
1576 a PendingDeprecation warning.
1577
Eric Smith63376222009-05-05 14:04:18 +00001578- Issue #5920: For float.__format__, change the behavior with the
1579 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1580 to be like 'g' but with at least one decimal point and with a
1581 default precision of 12. Previously, the behavior the same but with
1582 a default precision of 6. This more closely matches str(), and
1583 reduces surprises when adding alignment flags to the empty
1584 presentation type. This also affects the new complex.__format__ in
1585 the same way.
1586
Martin v. Löwis011e8422009-05-05 04:43:17 +00001587- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1588
R. David Murrayb18500d2009-05-04 22:59:07 +00001589- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1590 shadowed by classtype's, even if it was None. property now
1591 inserts the __doc__ into the subclass instance __dict__.
1592
Antoine Pitrou244651a2009-05-04 18:56:13 +00001593- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1594 sequences. Patch by Nick Barnes and Victor Stinner.
1595
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001596- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001597
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001598- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1599 received a new method, detach(). detach() disconnects the underlying stream
1600 from the buffer or text IO and returns it.
1601
Mark Dickinson33841c32009-05-01 15:37:04 +00001602- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1603 floats with absolute value over 1e50. Also remove length
1604 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1605 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001606
Eric Smith741191f2009-05-06 13:08:15 +00001607- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001608 format(complex(1, 2./3), '.5') now produces a sensible result.
1609
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001610- Issue #5864: Fix empty format code formatting for floats so that it
1611 never gives more than the requested number of significant digits.
1612
Eric Smith6dc46f52009-04-27 20:39:49 +00001613- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1614 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1615
Eric Smithcc32a112009-04-26 21:35:14 +00001616- Issue #5835: Deprecate PyOS_ascii_formatd.
1617
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001618- Issue #4971: Fix titlecase for characters that are their own
1619 titlecase, but not their own uppercase.
1620
Benjamin Peterson193152c2009-04-25 01:08:45 +00001621- Issue #5283: Setting __class__ in __del__ caused a segfault.
1622
Mark Dickinsonad476da2009-04-23 19:14:16 +00001623- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1624 z involves nans, infs or negative zeros.
1625
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001626- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001627
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001628- Issue #1869 (and many duplicates): make round(x, n) correctly
1629 rounded for a float x, by using the decimal <-> binary conversions
1630 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1631 consistently agrees with format(x, '.2f').
1632
Benjamin Petersonae937c02009-04-18 20:54:08 +00001633- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1634 some builtin types.
1635
Eric Smith0923d1d2009-04-16 20:16:10 +00001636- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1637
Eric Smith35e84722009-04-16 20:21:28 +00001638- Issue #5515: str.format() type 'n' combined with commas and leading
1639 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001640
1641- Implement PEP 378, Format Specifier for Thousands Separator, for
1642 floats.
1643
Mark Dickinson3370cce2009-04-17 22:40:53 +00001644- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001645 1e11, not 1e12. This avoids printing 13 significant digits in
1646 situations where only 12 of them are correct. Example problem
1647 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1648 long time.)
1649
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001650- Issue #1580: On most platforms, use a 'short' float repr: for a
1651 finite float x, repr(x) now outputs a string based on the shortest
1652 sequence of decimal digits that rounds to x. Previous behaviour was
1653 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001654 Another minor difference is that the new repr switches to
1655 exponential notation at 1e16 instead of the previous 1e17; this
1656 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001657
1658 There's a new sys attribute sys.float_repr_style, which takes
1659 the value 'short' to indicate that we're using short float repr,
1660 and 'legacy' if the short float repr isn't available for one
1661 reason or another.
1662
1663 The float repr change involves incorporating David Gay's 'perfect
1664 rounding' code into the Python core (it's in Python/dtoa.c). As a
1665 secondary consequence, all string-to-float and float-to-string
1666 conversions (including all float formatting operations) will be
1667 correctly rounded on these platforms.
1668
1669 See issue 1580 discussions for details of platforms for which
1670 this change does not apply.
1671
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001672- Issue #5759: float() didn't call __float__ on str subclasses.
1673
Georg Brandlabc38772009-04-12 15:51:51 +00001674- The string.maketrans() function is deprecated; there is a new static method
1675 maketrans() on the bytes and bytearray classes. This removes confusion about
1676 the types string.maketrans() is supposed to work with, and mirrors the
1677 methods available on the str class.
1678
R. David Murraydc6da8a2009-04-09 22:16:43 +00001679- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1680 its clarity and its speed.
1681
Matthias Klose091c7b12009-04-07 13:24:27 +00001682- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1683 to avoid compiler warnings.
1684
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001685- Issue #3739: The unicode-internal encoder now reports the number of characters
1686 consumed like any other encoder (instead of the number of bytes).

1828
Brett Cannon0759dd62009-04-01 18:13:07 +00001829- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1830
Georg Brandlab6f2f62009-03-31 04:16:10 +00001831- Fix a segfault when running test_exceptions with coverage, caused by
1832 insufficient checks in accessors of Exception.__context__.
1833
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001834- Issue #5604: non-ASCII characters in module name passed to
1835 imp.find_module() were converted to UTF-8 while the path is
1836 converted to the default filesystem encoding, causing nonsense.

1839
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001840- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1841 the end sys.path, for compatibility with the system install of Python.
1842
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001843- Issue #4688: Add a heuristic so that tuples and dicts containing only
1844 untrackable objects are not tracked by the garbage collector. This can
1845 reduce the size of collections and therefore the garbage collection overhead
1846 on long-running programs, depending on their particular use of datatypes.
1847
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001848- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1860 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1861 and sizeof(Py_UNICODE) == 2.
1862
Eric Smith8ec90442009-03-14 12:29:34 +00001863- Issue #5237: Allow auto-numbered fields in str.format(). For

1865
Antoine Pitrou652e7072009-03-13 19:25:20 +00001866- Issue #5392: when a very low recursion limit was set, the interpreter would
1867 abort with a fatal error after the recursion limit was hit twice.
1868
Matthias Klose042f1332009-04-04 14:32:42 +00001869- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1915
Lars Gustäbel42e00912009-03-22 20:34:29 +00001916- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1917 forever on incomplete input. That caused tarfile.open() to hang when used
1918 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1919 partial bzip2 compressed data.
1920
Mark Dickinson79f52032009-03-17 23:12:51 +00001921- Issue #2110: Add support for thousands separator and 'n' type

1989 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1990 evaluation loop is compiled with a new dispatch mechanism which gives
1991 speedups of up to 20%, depending on the system, on various benchmarks.

2007 to str, bytes and bytearray could be optimized away by the compiler, letting
2008 the interpreter segfault instead of raising an error.
2009
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002010- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2036 flag to work properly. Furthermore, when specifying -u, the text stdout
2037 and stderr streams have line-by-line buffering enabled (the default being
2038 to buffer arbitrary chunks of data).
2039
Raymond Hettinger35631532009-01-09 03:58:09 +00002040- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

2043
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002044- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2045 an existing .py counterpart, override the co_filename attributes of all
2046 code objects if the original filename is obsolete (which can happen if the
2047 file has been renamed, moved, or if it is accessed through different paths).
2048 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2049
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002050- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2051 one byte. Also fixes the meaning of len() so that it returns the number of
2052 items, rather than the size in bytes.
2053
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002054- Issue #4075: Use OutputDebugStringW in Py_FatalError.

2067
Georg Brandlccc47b62008-12-28 11:44:14 +00002068- Issue #4759: None is now allowed as the first argument of

2120 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2121 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2122 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00002442- Issue #5008: When a file is opened in append mode with the new IO library,
2443 do an explicit seek to the end of file (so that e.g. tell() returns the
