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.

Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000342- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
343 where the method could block indefinitely if called just before the
344 event loop started running. This also fixes the occasional freezes
345 witnessed in test_httpservers.
346
Antoine Pitrou40f08742010-04-24 22:04:40 +0000347- Issue #8524: When creating an SSL socket, the timeout value of the
348 original socket wasn't retained (instead, a socket with a positive timeout
349 would be turned into a non-blocking SSL socket).
350
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000351- Issue #5103: SSL handshake would ignore the socket timeout and block
352 indefinitely if the other end didn't respond.
353
354- The do_handshake() method of SSL objects now adjusts the blocking mode of
355 the SSL structure if necessary (as other methods already do).
356
Victor Stinner13bb71c2010-04-23 21:41:56 +0000357- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
358 and bytes strings for environment keys and values
359
Victor Stinner4d078042010-04-23 19:28:32 +0000360- Issue #8467: Pure Python implementation of subprocess encodes the error
361 message using surrogatepass error handler to support surrogates in the
362 message
363
Victor Stinner349fd522010-04-23 10:56:17 +0000364- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
365
Sean Reifscheider13daf122010-04-23 09:29:52 +0000366- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
367 the string "python" as the *ident*. openlog() arguments are all optional
368 and keywords.
369
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000370- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
371 a non-infinite timeout. Also make that method friendlier with applications
372 wanting to continue using the socket in clear-text mode, by disabling
373 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
374
Antoine Pitrou7062db82010-04-22 13:30:10 +0000375- Issue #8496: make mailcap.lookup() always return a list, rather than an
376 iterator. Patch by Gregory Nofi.
377
Victor Stinner35466c52010-04-22 11:23:23 +0000378- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
379 collation name contains a surrogate character.
380
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000381- Issue #8484: Load all ciphers and digest algorithms when initializing
382 the _ssl extension, such that verification of some SSL certificates
383 doesn't fail because of an "unknown algorithm".
384
Tarek Ziadéfb437512010-04-20 08:57:33 +0000385- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
386
Tarek Ziadé5340db32010-04-19 22:30:51 +0000387- Issue #1540112: Now allowing the choice of a copy function in
388 shutil.copytree.
389
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000390- Issue #4814: timeout parameter is now applied also for connections resulting
391 from PORT/EPRT commands.
392
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000393- Issue #8463: added missing reference to bztar in shutil's documentation.
394
Ronald Oussoren84151202010-04-18 20:46:11 +0000395- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
396 (as long as the user didn't specify 'automatic proxy configuration').
397
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000398- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
399 code as stated in RFC-959 at chapter 5.4.
400
Victor Stinner738446f02010-04-18 00:00:44 +0000401- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
402 surrogates.
403
Antoine Pitrou0454af92010-04-17 23:51:58 +0000404- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000405 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000407- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
408 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
409
Victor Stinner0e59cc32010-04-16 23:49:32 +0000410- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
411 the current working directory.
412
Victor Stinner5bfe1462010-04-16 13:28:05 +0000413- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
414 using backslashreplace error handler
415
Victor Stinnercfa72782010-04-16 11:45:13 +0000416- Issue #8412: os.system() now accepts bytes, bytearray and str with

418
Senthil Kumaranad02d232010-04-16 03:02:13 +0000419- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
420 Locke and Hans Ulrich Niedermann.
421
R. David Murrayd48739f2010-04-14 18:59:18 +0000422- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
423
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000424- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
425 module now takes an optional timeout argument in seconds. Timeout support
426 relies on the system threading library, so as to avoid a semi-busy wait
427 loop.
428
Victor Stinner485fb562010-04-13 11:07:24 +0000429- Issue #8383: pickle and pickletools use surrogatepass error handler when
430 encoding unicode as utf8 to support lone surrogates and stay compatible with
431 Python 2.x and 3.0
432
R. David Murrayb2416e52010-04-12 16:58:02 +0000433- Issue #7585: difflib context and unified diffs now place a tab between
434 filename and date, conforming to the 'standards' they were originally
435 designed to follow. This improves compatibility with patch tools.
436
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000437- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
438 character sets will now consistently use a Content-Transfer-Encoding of
439 7bit rather than sometimes being marked as 8bit.
440
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000441- Issue #8375: test_distutils now checks if the temporary directory are still
442 present before it cleans them.
443
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000444- Issue #8374: Update the internal alias table in the :mod:`locale` module
445 to cover recent locale changes and additions.
446
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000447- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
448 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
449 and `ssl.OPENSSL_VERSION_NUMBER`.
450
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000451- Add functools.total_ordering() and functools.cmp_to_key().
452
Mark Dickinson089b00c2010-04-03 15:51:03 +0000453- Issue #8257: The Decimal construct now accepts a float instance
454 directly, converting that float to a Decimal of equal value:
455
456 >>> Decimal(1.1)
457 Decimal('1.100000000000000088817841970012523233890533447265625')
458
Mark Dickinson98127c32010-04-03 11:18:52 +0000459- Issue #8294: The Fraction constructor now accepts Decimal and float
460 instances directly.
461
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000462- Issue #7279: Comparisons involving a Decimal signaling NaN now
463 signal InvalidOperation instead of returning False. (Comparisons
464 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
465 are now hashable; Decimal signaling NaNs remain unhashable.
466
467- Issue #2531: Comparison operations between floats and Decimal
468 instances now return a result based on the numeric values of the
469 operands; previously they returned an arbitrary result based on
470 the relative ordering of id(float) and id(Decimal).
471
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000472- Added a subtract() method to collections.Counter().
473
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000474- Issue #8233: When run as a script, py_compile.py optionally takes a single
475 argument `-` which tells it to read files to compile from stdin. Each line
476 is read on demand and the named file is compiled immediately. (Original
477 patch by Piotr Ożarowski).
478
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000479- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
480 form feed (0x0C) are now considered linebreaks, as specified in Unicode
481 Standard Annex #14. See issue #7643.
482 http://www.unicode.org/reports/tr14/
483
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000484- Comparisons using one of <, <=, >, >= between a complex instance and
485 a Fractions instance now raise TypeError instead of returning
486 True/False. This makes Fraction <=> complex comparisons consistent with
487 int <=> complex, float <=> complex, and complex <=> complex comparisons.
488
Antoine Pitrou39b35432010-03-23 00:25:54 +0000489- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
490 some methods (such as oss_mixer_device.fileno()) were not available.
491 Initial patch by Bertrand Janin.
492
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000493- Issue #8205: Remove the "Modules" directory from sys.path when Python is
494 running from the build directory (POSIX only).
495
Antoine Pitrou910bd512010-03-22 20:11:09 +0000496- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
497 didn't support chflags() (for example ZFS under FreeBSD). The error is
498 now silenced.
499
R. David Murrayca2edce2010-03-22 17:48:48 +0000500- Issue #7860: platform.uname now reports the correct 'machine' type
501 when Python is running in WOW64 mode on 64 bit Windows.
502
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000503- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
504 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
505 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000506
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000507- Issue #4282: Fix the main function of the profile module for a non-ASCII
508 script, open the file in binary mode and not in text mode with the default
509 (utf8) encoding.
510
Florent Xicluna54467e02010-03-21 12:29:50 +0000511- Issue #8179: Fix macpath.realpath() on a non-existing path.
512
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000513- Issue #8024: Update the Unicode database to 5.2.
514
Benjamin Peterson00888932010-03-18 22:37:38 +0000515- Issue #8168: py_compile now handles files with utf-8 BOMS.
516
Benjamin Peterson689a5582010-03-18 22:29:52 +0000517- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
518 detected.
519
Martin v. Löwis4b003072010-03-16 13:19:21 +0000520- Issue #6716/2: Backslash-replace error output in compilall.
521
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000522- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
523 with Tcl/Tk-8.5.
524
Matthias Klosec33b9022010-03-16 00:36:26 +0000525- Issue #8140: extend compileall to compile single files. Add -i option.
526
Matthias Klose82f60912010-03-15 13:46:04 +0000527- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
528 the locale.
529
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000530- The internals of the subprocess module on POSIX systems have been replaced
531 by an extension module (_posixsubprocess) so that the fork()+exec() can be
532 done safely without the possibility of deadlock in multithreaded applications.
533
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000534- subprocess.Popen now has restore_signals and start_new_session features.
535 The default of restore_signals=True is a new behavior compared to earlier
536 Python versions. This means that signals such as SIGPIPE are not ignored
537 by default in subprocesses launched by Python (Issue #1652).
538
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000539- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
540 cElementTree module is updated too.

549 the replacement were all bytes. Patch by Antoine Pitrou.
550
Gerhard Häringf9cee222010-03-05 15:20:03 +0000551- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
552 bugs and allows loading SQLite extensions from shared libraries.

Florent Xiclunac279ebf2010-02-27 11:31:21 +0000568- Issue #691291: codecs.open() should not convert end of lines on reading and
569 writing.
570

583
Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +0000584- Issue #6666: fix bug in trace.py that applied the list of directories
585 to be ignored only to the first file. Noted by Bogdan Opanchuk.
586
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000587- Issue #7597: curses.use_env() can now be called before initscr().
588 Noted by Kan-Ru Chen.
589
Ezio Melotti19e4acf2010-02-22 15:59:01 +0000590- Issue #7310: fix the __repr__ of os.environ to show the environment variables.

596 bytecode file when it was less then 8 bytes.
597
Mark Dickinson84230a12010-02-18 14:49:50 +0000598- Issue #7633: In the decimal module, Context class methods (with the
599 exception of canonical and is_canonical) now accept instances of int
600 and long wherever a Decimal instance is accepted, and implicitly
601 convert that argument to Decimal. Previously only some arguments
602 were converted.
603
R. David Murray1f449142010-02-11 00:15:05 +0000604- Issue #7835: shelve should no longer produce mysterious warnings during
605 interpreter shutdown.
606
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000607- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
608 in XML processing instructions and comments. These raw characters are
609 allowed by the XML specification, and are necessary when outputting e.g.

622 type is specified. Patch by Brian Curtin.
623
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000624- Issue #6939: Fix file I/O objects in the `io` module to keep the original
625 file position when calling `truncate()`. It would previously change the
626 file position to the given argument, which goes against the tradition of
627 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
628
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000629- Issue #7610: Reworked implementation of the internal
630 :class:`zipfile.ZipExtFile` class used to represent files stored inside
631 an archive. The new implementation is significantly faster and can
632 be wrapped in a :class:`io.BufferedReader` object for more speedups.
633 It also solves an issue where interleaved calls to `read()` and
634 `readline()` give wrong results. Patch by Nir Aides.
635
Jesse Noller1f0b6582010-01-27 03:36:01 +0000636- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

638 the worker before that worker is terminated, and a new one created to
639 replace it.

796
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000797- Issue #6816: runpy now provides a run_path function that allows Python code
798 to execute file paths that refer to source or compiled Python files as well
799 as zipfiles, directories and other valid sys.path entries that contain a
800 __main__.py file. This allows applications that run other Python scripts to
801 support the same flexibility as the CPython command line itself.
802
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000803- Issue #7318: multiprocessing now uses a timeout when it fails to establish

839 failures on systems with slightly bogus mtime behaviour.
840
Gregory P. Smith50467882009-11-01 18:42:17 +0000841- Issue #7246 & Issue #7208: getpass now properly flushes input before
842 reading from stdin so that existing input does not confuse it and

R. David Murray378c0cf2010-02-24 01:46:21 +00001205- Issue #6292: for the moment at least, the test suite runs cleanly if python
1206 is run with the -OO flag. Tests requiring docstrings are skipped.
1207
Ezio Melotti184bdfb2010-02-18 09:37:05 +00001208- Issue #7712: test.support gained a new `temp_cwd` context manager which is
1209 now also used by regrtest to run all the tests in a temporary directory.
1210 The original CWD is saved in `support.SAVEDCWD`.
1211 Thanks to Florent Xicluna who helped with the patch.
1212

1215 wasn't built), due to an uncleared exception.
1216
Florent Xicluna3f88c0e2010-03-19 14:40:31 +00001217- Issue #7728: test_timeout was changed to use support.bind_port instead of a
1218 hard coded port.
R. David Murraye9e95932010-02-06 05:00:15 +00001219
R. David Murray445448c2009-12-20 17:28:31 +00001220- Issue #7376: instead of running a self-test (which was failing) when called
1221 with no arguments, doctest.py now gives a usage message.
1222
R. David Murrayef1992b2009-12-16 15:19:27 +00001223- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.

1227
R. David Murrayba311052009-12-04 00:09:14 +00001228- Issue #7431: use TESTFN in test_linecache instead of trying to create a
1229 file in the Lib/test directory, which might be read-only for the
1230 user running the tests.
1231
R. David Murray35768ad2009-11-15 00:23:21 +00001232- Issue #7324: add a sanity check to regrtest argument parsing to
1233 catch the case of an option with no handler.
1234
R. David Murray7dc72cc2009-11-14 16:13:02 +00001235- Issue #7312: Add a -F flag to run the selected tests in a loop until
1236 a test fails. Can be combined with -j.
1237
Antoine Pitrou060cee22009-11-13 16:29:04 +00001238- Issue #6551: test_zipimport could import and then destroy some modules of
1239 the encodings package, which would make other tests fail further down
1240 the road because the internally cached encoders and decoders would point
1241 to empty global variables.
1242
Antoine Pitrou941ee882009-11-11 20:59:38 +00001243- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1247
Brett Cannoncfed0292009-11-05 01:26:57 +00001248- Issue #7248 (part 2): Use a unique temporary directory for importlib source
1249 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1250 between concurrent executions on the same system.
1251
Brett Cannon0ae45112009-11-05 01:17:22 +00001252- Issue #7248: In importlib.test.source.util a try/finally block did not make
1253 sure that some referenced objects actually were created in the block before
1254 calling methods on the object.
1255
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001256- Issue #7222: Make thread "reaping" more reliable so that reference
1257 leak-chasing test runs give sensible results. The previous method of
1258 reaping threads could return successfully while some Thread objects were
1259 still referenced. This also introduces a new private function:
1260 :func:`_thread._count()`.
1261
R. David Murray27144602009-10-19 15:26:16 +00001262- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1263 longer runs the risk of causing the worker thread to fail.
1264
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001265- Issue #7055: test___all__ now greedily detects all modules which have an
1266 __all__ attribute, rather than using a hardcoded and incomplete list.
1267
R. David Murray0bc11ae2009-10-18 22:18:17 +00001268- Issue #7058: Added save/restore for things like sys.argv and cwd to
1269 runtest_inner in regrtest, with warnings if the called test modifies them,
1270 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001271
Mark Dickinson2e304402009-10-04 18:43:54 +00001272- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1273
Brett Cannon3c273842009-07-20 00:14:29 +00001274- Fixed tests in importlib.test.source.test_abc_loader that were masking
1275 the proper exceptions that should be raised for missing or improper code
1276 object bytecode.
1277
Brett Cannonb49c70c2009-07-15 04:08:33 +00001278- Removed importlib's custom test discovery code and switched to
1279 unittest.TestLoader.discover().

Antoine Pitroue4501852009-05-14 18:55:55 +00001493- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1494 library. This means, for example, that opening an UTF-16 text file in
1495 append mode doesn't add a BOM at the end of the file if the file isn't
1496 empty.
1497
R. David Murray74b89242009-05-13 17:33:03 +00001498- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1499 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1500 corrects a pydoc regression.
1501
R. David Murray99352742009-05-07 18:24:38 +00001502- Issue 5955: aifc's close method did not close the file it wrapped,
1503 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001545
1546Core and Builtins
1547-----------------
1548
Mark Dickinson865e01a2009-05-07 16:37:01 +00001549- Issue #5914: Add new C API function PyOS_string_to_double, and
1550 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1551
Eric Smith741191f2009-05-06 13:08:15 +00001552- Issue #3382: float.__format__, complex.__format__, and %-formatting
1553 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1554 affects nan -> NAN and inf -> INF.
1555
Mark Hammond5a607a32009-05-06 08:04:54 +00001556- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1557 in all operations, including splitdrive, split, etc. splitunc() now issues
1558 a PendingDeprecation warning.
1559
Eric Smith63376222009-05-05 14:04:18 +00001560- Issue #5920: For float.__format__, change the behavior with the
1561 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1562 to be like 'g' but with at least one decimal point and with a
1563 default precision of 12. Previously, the behavior the same but with
1564 a default precision of 6. This more closely matches str(), and
1565 reduces surprises when adding alignment flags to the empty
1566 presentation type. This also affects the new complex.__format__ in
1567 the same way.
1568
Martin v. Löwis011e8422009-05-05 04:43:17 +00001569- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1570
R. David Murrayb18500d2009-05-04 22:59:07 +00001571- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1572 shadowed by classtype's, even if it was None. property now
1573 inserts the __doc__ into the subclass instance __dict__.
1574
Antoine Pitrou244651a2009-05-04 18:56:13 +00001575- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1576 sequences. Patch by Nick Barnes and Victor Stinner.
1577
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001578- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001579
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001580- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1581 received a new method, detach(). detach() disconnects the underlying stream
1582 from the buffer or text IO and returns it.
1583
Mark Dickinson33841c32009-05-01 15:37:04 +00001584- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1585 floats with absolute value over 1e50. Also remove length
1586 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1587 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001588
Eric Smith741191f2009-05-06 13:08:15 +00001589- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001590 format(complex(1, 2./3), '.5') now produces a sensible result.
1591
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001592- Issue #5864: Fix empty format code formatting for floats so that it
1593 never gives more than the requested number of significant digits.
1594
Eric Smith6dc46f52009-04-27 20:39:49 +00001595- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1596 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1597
Eric Smithcc32a112009-04-26 21:35:14 +00001598- Issue #5835: Deprecate PyOS_ascii_formatd.
1599
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001600- Issue #4971: Fix titlecase for characters that are their own
1601 titlecase, but not their own uppercase.
1602
Benjamin Peterson193152c2009-04-25 01:08:45 +00001603- Issue #5283: Setting __class__ in __del__ caused a segfault.
1604
Mark Dickinsonad476da2009-04-23 19:14:16 +00001605- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1606 z involves nans, infs or negative zeros.
1607
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001608- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001609
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001610- Issue #1869 (and many duplicates): make round(x, n) correctly
1611 rounded for a float x, by using the decimal <-> binary conversions
1612 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1613 consistently agrees with format(x, '.2f').
1614
Benjamin Petersonae937c02009-04-18 20:54:08 +00001615- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1616 some builtin types.
1617
Eric Smith0923d1d2009-04-16 20:16:10 +00001618- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1619
Eric Smith35e84722009-04-16 20:21:28 +00001620- Issue #5515: str.format() type 'n' combined with commas and leading
1621 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001622
1623- Implement PEP 378, Format Specifier for Thousands Separator, for
1624 floats.
1625
Mark Dickinson3370cce2009-04-17 22:40:53 +00001626- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001627 1e11, not 1e12. This avoids printing 13 significant digits in
1628 situations where only 12 of them are correct. Example problem
1629 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1630 long time.)
1631
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001632- Issue #1580: On most platforms, use a 'short' float repr: for a
1633 finite float x, repr(x) now outputs a string based on the shortest
1634 sequence of decimal digits that rounds to x. Previous behaviour was
1635 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001636 Another minor difference is that the new repr switches to
1637 exponential notation at 1e16 instead of the previous 1e17; this
1638 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001639
1640 There's a new sys attribute sys.float_repr_style, which takes
1641 the value 'short' to indicate that we're using short float repr,
1642 and 'legacy' if the short float repr isn't available for one
1643 reason or another.
1644
1645 The float repr change involves incorporating David Gay's 'perfect
1646 rounding' code into the Python core (it's in Python/dtoa.c). As a
1647 secondary consequence, all string-to-float and float-to-string
1648 conversions (including all float formatting operations) will be
1649 correctly rounded on these platforms.
1650
1651 See issue 1580 discussions for details of platforms for which
1652 this change does not apply.
1653
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001654- Issue #5759: float() didn't call __float__ on str subclasses.
1655
Georg Brandlabc38772009-04-12 15:51:51 +00001656- The string.maketrans() function is deprecated; there is a new static method
1657 maketrans() on the bytes and bytearray classes. This removes confusion about
1658 the types string.maketrans() is supposed to work with, and mirrors the
1659 methods available on the str class.
1660
R. David Murraydc6da8a2009-04-09 22:16:43 +00001661- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1662 its clarity and its speed.
1663
Matthias Klose091c7b12009-04-07 13:24:27 +00001664- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1665 to avoid compiler warnings.
1666
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001667- Issue #3739: The unicode-internal encoder now reports the number of characters
1668 consumed like any other encoder (instead of the number of bytes).

1804
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001805- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1806 byte, and the 'C' code only accepts a unicode character.
1807
Georg Brandl406b3d82009-04-11 21:24:37 +00001808- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1809 when hitting the recursion limit under certain circumstances.
1810
Brett Cannon0759dd62009-04-01 18:13:07 +00001811- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1812
Georg Brandlab6f2f62009-03-31 04:16:10 +00001813- Fix a segfault when running test_exceptions with coverage, caused by
1814 insufficient checks in accessors of Exception.__context__.
1815
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001816- Issue #5604: non-ASCII characters in module name passed to
1817 imp.find_module() were converted to UTF-8 while the path is
1818 converted to the default filesystem encoding, causing nonsense.
1819
Benjamin Peterson09832742009-03-26 17:15:46 +00001820- Issue #5126: str.isprintable() returned False for space characters.
1821
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001822- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1823 the end sys.path, for compatibility with the system install of Python.
1824
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001825- Issue #4688: Add a heuristic so that tuples and dicts containing only
1826 untrackable objects are not tracked by the garbage collector. This can
1827 reduce the size of collections and therefore the garbage collection overhead
1828 on long-running programs, depending on their particular use of datatypes.
1829
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001830- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1835 2**15 for the internal representation of integers, for performance
1836 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1837 --enable-big-digits option to configure, which overrides the
1838 default. Add sys.int_info structseq to provide information about
1839 the internal format.
1840
Mark Dickinson081dfee2009-03-18 14:47:41 +00001841- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1842 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1843 and sizeof(Py_UNICODE) == 2.
1844
Eric Smith8ec90442009-03-14 12:29:34 +00001845- Issue #5237: Allow auto-numbered fields in str.format(). For

1847
Antoine Pitrou652e7072009-03-13 19:25:20 +00001848- Issue #5392: when a very low recursion limit was set, the interpreter would
1849 abort with a fatal error after the recursion limit was hit twice.
1850
Matthias Klose042f1332009-04-04 14:32:42 +00001851- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
1852 short file names.

Brett Cannon7f6b4f82009-03-30 21:30:26 +00001883- Issue #5236: Change time.strptime() to only take strings. Didn't work with
1884 bytes already but the failure was non-obvious.
1885
Jesse Noller7af4ef82009-03-30 16:47:15 +00001886- Issue #5177: Multiprocessing's SocketListener class now uses

1897
Lars Gustäbel42e00912009-03-22 20:34:29 +00001898- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1899 forever on incomplete input. That caused tarfile.open() to hang when used
1900 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1901 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001922 struct.error instead of returning b'\xff\xff\xff\xff'. The
1923 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1924 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00001951- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1952 it now forces its argument to double before testing for infinity.
1953
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001954- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1955 returns a non-number type.
1956
Benjamin Peterson87618552009-02-08 15:00:52 +00001957- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001963
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001964- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001965 were suppressing all exceptions. These include list() and bytearray().
1966
Mark Dickinson1124e712009-01-28 21:25:58 +00001967- Issue #4707: round(x, n) now returns an integer if x is an integer.
1968 Previously it returned a float.
1969
Antoine Pitroub52ec782009-01-25 16:34:23 +00001970- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1971 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1972 evaluation loop is compiled with a new dispatch mechanism which gives
1973 speedups of up to 20%, depending on the system, on various benchmarks.
1974
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001975- Issue #4874: Most builtin decoders now reject unicode input.

1983 optional module state data.
1984
Mark Dickinson8055afd2009-01-17 10:04:45 +00001985- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1986 type to (void *).
1987
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001988- Issue #4935: The overflow checking code in the expandtabs() method common
1989 to str, bytes and bytearray could be optimized away by the compiler, letting
1990 the interpreter segfault instead of raising an error.
1991
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001992- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1993 __next__ method.
1994
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001995- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

2004 common cases are optimized thanks to a dedicated fast path and a moderate
2005 amount of loop unrolling.
2006
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002007- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2008 collecting the oldest generation) so that allocating lots of objects without
2009 destroying them does not show quadratic performance. Based on a proposal by
2010 Martin von Löwis at
2011 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2012
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002013- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002014 having been closed (for instance, a read() call could return some
2015 previously buffered data). Patch by Dmitry Vasiliev.
2016
Antoine Pitrou05608432009-01-09 18:53:14 +00002017- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2018 flag to work properly. Furthermore, when specifying -u, the text stdout
2019 and stderr streams have line-by-line buffering enabled (the default being
2020 to buffer arbitrary chunks of data).
2021
Raymond Hettinger35631532009-01-09 03:58:09 +00002022- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2023 instead of ints (reducing its size from 4 to 8 times thereby reducing
2024 Python's overall memory).
2025
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002026- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2027 an existing .py counterpart, override the co_filename attributes of all
2028 code objects if the original filename is obsolete (which can happen if the
2029 file has been renamed, moved, or if it is accessed through different paths).
2030 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2031
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002032- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2033 one byte. Also fixes the meaning of len() so that it returns the number of
2034 items, rather than the size in bytes.
2035
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002036- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2037
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002038- Issue #4747: When the terminal does not use utf-8, executing a script with
2039 non-ascii characters in its name could fail with a "SyntaxError: None" error.

Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002043
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002044- Issue #3680: Reference cycles created through a dict, set or deque iterator
2045 did not get collected.
2046
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002047- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2048 where the tp_hash and tp_dict slots are both NULL.
2049
Georg Brandlccc47b62008-12-28 11:44:14 +00002050- Issue #4759: None is now allowed as the first argument of
2051 bytearray.translate(). It was always allowed for bytes.translate().
2052
Skip Montanaro80072cb2008-12-23 03:51:14 +00002053- Added test case to ensure attempts to read from a file opened for writing
2054 fail.

2060
Antoine Pitrou621601a2008-12-17 23:18:19 +00002061- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2062 print elapsed times, not only when some objects are uncollectable /
2063 unreachable. Original patch by Neil Schemenauer.
2064
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002065- Issue #3439: Add a bit_length method to int.
2066
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002067- Issue #2173: When getting device encoding, check that return value of
2068 nl_langinfo is not the empty string. This was causing silent build
2069 failures on OS X.
2070
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002071- Issue #4597: Fixed several opcodes that weren't always propagating
2072 exceptions.
2073
2074- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002075 context manager returns a value that cannot be converted to a bool.
2076
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002077- Issue #4445: Replace "sizeof(PyBytesObject)" with
2078 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2079 bytes instances. On a typical machine this saves 3 bytes of memory

2423
Antoine Pitrou08838b62009-01-21 00:55:13 +00002424- Issue #5008: When a file is opened in append mode with the new IO library,
2425 do an explicit seek to the end of file (so that e.g. tell() returns the
2426 file size rather than 0). This is consistent with the behaviour of the
2427 traditional 2.x file object.

2457 appropriately when it is being used via socket.makefile() objects
2458 rather than delaying the close by waiting for garbage collection to do it.

2710 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2711 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2712 skip the tests if DISPLAY is defined but can't be used.
2713
R. David Murraya21e4ca2009-03-31 23:16:50 +00002714- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002715 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002716 from test support, which does the conversion.
