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.

R. David Murrayad78d152010-04-27 02:45:53 +0000347- Issue #6656: fix locale.format_string to handle escaped percents
348 and mappings.
349
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000350- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
351 where the method could block indefinitely if called just before the
352 event loop started running. This also fixes the occasional freezes
353 witnessed in test_httpservers.
354
Antoine Pitrou40f08742010-04-24 22:04:40 +0000355- Issue #8524: When creating an SSL socket, the timeout value of the
356 original socket wasn't retained (instead, a socket with a positive timeout
357 would be turned into a non-blocking SSL socket).
358
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000359- Issue #5103: SSL handshake would ignore the socket timeout and block
360 indefinitely if the other end didn't respond.
361
362- The do_handshake() method of SSL objects now adjusts the blocking mode of
363 the SSL structure if necessary (as other methods already do).
364
Victor Stinner13bb71c2010-04-23 21:41:56 +0000365- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates

373
Sean Reifscheider13daf122010-04-23 09:29:52 +0000374- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
375 the string "python" as the *ident*. openlog() arguments are all optional
376 and keywords.
377
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000378- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
379 a non-infinite timeout. Also make that method friendlier with applications
380 wanting to continue using the socket in clear-text mode, by disabling
381 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
382
Antoine Pitrou7062db82010-04-22 13:30:10 +0000383- Issue #8496: make mailcap.lookup() always return a list, rather than an
384 iterator. Patch by Gregory Nofi.
385
Victor Stinner35466c52010-04-22 11:23:23 +0000386- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
387 collation name contains a surrogate character.
388
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000389- Issue #8484: Load all ciphers and digest algorithms when initializing
390 the _ssl extension, such that verification of some SSL certificates
391 doesn't fail because of an "unknown algorithm".
392
Tarek Ziadéfb437512010-04-20 08:57:33 +0000393- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
394
Tarek Ziadé5340db32010-04-19 22:30:51 +0000395- Issue #1540112: Now allowing the choice of a copy function in
396 shutil.copytree.
397
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000398- Issue #4814: timeout parameter is now applied also for connections resulting
399 from PORT/EPRT commands.
400
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000401- Issue #8463: added missing reference to bztar in shutil's documentation.
402
Ronald Oussoren84151202010-04-18 20:46:11 +0000403- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
404 (as long as the user didn't specify 'automatic proxy configuration').
405
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000406- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
407 code as stated in RFC-959 at chapter 5.4.
408
Victor Stinner738446f02010-04-18 00:00:44 +0000409- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
410 surrogates.
411
Antoine Pitrou0454af92010-04-17 23:51:58 +0000412- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000413 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

428 Locke and Hans Ulrich Niedermann.
429
R. David Murrayd48739f2010-04-14 18:59:18 +0000430- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
431
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000432- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
433 module now takes an optional timeout argument in seconds. Timeout support
434 relies on the system threading library, so as to avoid a semi-busy wait
435 loop.
436
Victor Stinner485fb562010-04-13 11:07:24 +0000437- Issue #8383: pickle and pickletools use surrogatepass error handler when
438 encoding unicode as utf8 to support lone surrogates and stay compatible with
439 Python 2.x and 3.0
440
R. David Murrayb2416e52010-04-12 16:58:02 +0000441- Issue #7585: difflib context and unified diffs now place a tab between
442 filename and date, conforming to the 'standards' they were originally
443 designed to follow. This improves compatibility with patch tools.
444
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000445- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
446 character sets will now consistently use a Content-Transfer-Encoding of
447 7bit rather than sometimes being marked as 8bit.
448
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000449- Issue #8375: test_distutils now checks if the temporary directory are still
450 present before it cleans them.
451
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000452- Issue #8374: Update the internal alias table in the :mod:`locale` module
453 to cover recent locale changes and additions.
454
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000455- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
456 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
457 and `ssl.OPENSSL_VERSION_NUMBER`.
458
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000459- Add functools.total_ordering() and functools.cmp_to_key().
460
Mark Dickinson089b00c2010-04-03 15:51:03 +0000461- Issue #8257: The Decimal construct now accepts a float instance
462 directly, converting that float to a Decimal of equal value:
463
464 >>> Decimal(1.1)
465 Decimal('1.100000000000000088817841970012523233890533447265625')
466
Mark Dickinson98127c32010-04-03 11:18:52 +0000467- Issue #8294: The Fraction constructor now accepts Decimal and float
468 instances directly.
469
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000470- Issue #7279: Comparisons involving a Decimal signaling NaN now
471 signal InvalidOperation instead of returning False. (Comparisons
472 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
473 are now hashable; Decimal signaling NaNs remain unhashable.
474
475- Issue #2531: Comparison operations between floats and Decimal
476 instances now return a result based on the numeric values of the
477 operands; previously they returned an arbitrary result based on
478 the relative ordering of id(float) and id(Decimal).
479
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000480- Added a subtract() method to collections.Counter().
481
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000482- Issue #8233: When run as a script, py_compile.py optionally takes a single
483 argument `-` which tells it to read files to compile from stdin. Each line
484 is read on demand and the named file is compiled immediately. (Original
485 patch by Piotr Ożarowski).
486
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000487- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
488 form feed (0x0C) are now considered linebreaks, as specified in Unicode
489 Standard Annex #14. See issue #7643.
490 http://www.unicode.org/reports/tr14/
491
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000492- Comparisons using one of <, <=, >, >= between a complex instance and
493 a Fractions instance now raise TypeError instead of returning
494 True/False. This makes Fraction <=> complex comparisons consistent with
495 int <=> complex, float <=> complex, and complex <=> complex comparisons.
496
Antoine Pitrou39b35432010-03-23 00:25:54 +0000497- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
498 some methods (such as oss_mixer_device.fileno()) were not available.
499 Initial patch by Bertrand Janin.
500
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000501- Issue #8205: Remove the "Modules" directory from sys.path when Python is
502 running from the build directory (POSIX only).
503
Antoine Pitrou910bd512010-03-22 20:11:09 +0000504- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
505 didn't support chflags() (for example ZFS under FreeBSD). The error is
506 now silenced.
507
R. David Murrayca2edce2010-03-22 17:48:48 +0000508- Issue #7860: platform.uname now reports the correct 'machine' type
509 when Python is running in WOW64 mode on 64 bit Windows.
510
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000511- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
512 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
513 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000514
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000515- Issue #4282: Fix the main function of the profile module for a non-ASCII
516 script, open the file in binary mode and not in text mode with the default
517 (utf8) encoding.
518
Florent Xicluna54467e02010-03-21 12:29:50 +0000519- Issue #8179: Fix macpath.realpath() on a non-existing path.

524
Benjamin Peterson689a5582010-03-18 22:29:52 +0000525- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
526 detected.
527
Martin v. Löwis4b003072010-03-16 13:19:21 +0000528- Issue #6716/2: Backslash-replace error output in compilall.
529
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000530- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
531 with Tcl/Tk-8.5.
532
Matthias Klosec33b9022010-03-16 00:36:26 +0000533- Issue #8140: extend compileall to compile single files. Add -i option.

536 the locale.
537
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000538- The internals of the subprocess module on POSIX systems have been replaced
539 by an extension module (_posixsubprocess) so that the fork()+exec() can be
540 done safely without the possibility of deadlock in multithreaded applications.
541
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000542- subprocess.Popen now has restore_signals and start_new_session features.
543 The default of restore_signals=True is a new behavior compared to earlier
544 Python versions. This means that signals such as SIGPIPE are not ignored
545 by default in subprocesses launched by Python (Issue #1652).
546
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000547- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

557 the replacement were all bytes. Patch by Antoine Pitrou.
558
Gerhard Häringf9cee222010-03-05 15:20:03 +0000559- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
560 bugs and allows loading SQLite extensions from shared libraries.

Florent Xiclunac279ebf2010-02-27 11:31:21 +0000576- Issue #691291: codecs.open() should not convert end of lines on reading and
577 writing.
578

Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +0000592- Issue #6666: fix bug in trace.py that applied the list of directories
593 to be ignored only to the first file. Noted by Bogdan Opanchuk.
594
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000595- Issue #7597: curses.use_env() can now be called before initscr().
596 Noted by Kan-Ru Chen.
597
Ezio Melotti19e4acf2010-02-22 15:59:01 +0000598- Issue #7310: fix the __repr__ of os.environ to show the environment variables.

604 bytecode file when it was less then 8 bytes.
605
Mark Dickinson84230a12010-02-18 14:49:50 +0000606- Issue #7633: In the decimal module, Context class methods (with the
607 exception of canonical and is_canonical) now accept instances of int
608 and long wherever a Decimal instance is accepted, and implicitly
609 convert that argument to Decimal. Previously only some arguments
610 were converted.
611
R. David Murray1f449142010-02-11 00:15:05 +0000612- Issue #7835: shelve should no longer produce mysterious warnings during
613 interpreter shutdown.
614
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000615- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
616 in XML processing instructions and comments. These raw characters are
617 allowed by the XML specification, and are necessary when outputting e.g.
618 PHP code in a processing instruction. Patch by Neil Muller.

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

Antoine Pitroua32f9a22010-01-27 21:18:57 +0000637- Issue #7610: Reworked implementation of the internal
638 :class:`zipfile.ZipExtFile` class used to represent files stored inside
639 an archive. The new implementation is significantly faster and can
640 be wrapped in a :class:`io.BufferedReader` object for more speedups.
641 It also solves an issue where interleaved calls to `read()` and
642 `readline()` give wrong results. Patch by Nir Aides.
643
Jesse Noller1f0b6582010-01-27 03:36:01 +0000644- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

804
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000805- Issue #6816: runpy now provides a run_path function that allows Python code
806 to execute file paths that refer to source or compiled Python files as well
807 as zipfiles, directories and other valid sys.path entries that contain a
808 __main__.py file. This allows applications that run other Python scripts to
809 support the same flexibility as the CPython command line itself.
810
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000811- Issue #7318: multiprocessing now uses a timeout when it fails to establish

847 failures on systems with slightly bogus mtime behaviour.
848
Gregory P. Smith50467882009-11-01 18:42:17 +0000849- Issue #7246 & Issue #7208: getpass now properly flushes input before
850 reading from stdin so that existing input does not confuse it and

1199 from the local cache.
Florent Xiclunaf089fd62010-03-19 14:25:03 +00001200
Florent Xiclunab14930c2010-03-13 15:26:44 +00001201- Issue #7849: Now the utility ``check_warnings`` verifies if the warnings are
1202 effectively raised.
1203
Florent Xiclunac9c79782010-03-08 12:24:53 +00001204- The four path modules (genericpath, macpath, ntpath, posixpath) share a

R. David Murray378c0cf2010-02-24 01:46:21 +00001213- Issue #6292: for the moment at least, the test suite runs cleanly if python
1214 is run with the -OO flag. Tests requiring docstrings are skipped.
1215
Ezio Melotti184bdfb2010-02-18 09:37:05 +00001216- Issue #7712: test.support gained a new `temp_cwd` context manager which is
1217 now also used by regrtest to run all the tests in a temporary directory.
1218 The original CWD is saved in `support.SAVEDCWD`.
1219 Thanks to Florent Xicluna who helped with the patch.
1220
Mark Dickinsonedff7af2010-02-13 18:34:53 +00001221- Issue #7924: Fix an intermittent 'XXX undetected error' failure in

1223 wasn't built), due to an uncleared exception.
1224
Florent Xicluna3f88c0e2010-03-19 14:40:31 +00001225- Issue #7728: test_timeout was changed to use support.bind_port instead of a
1226 hard coded port.
R. David Murraye9e95932010-02-06 05:00:15 +00001227
R. David Murray445448c2009-12-20 17:28:31 +00001228- Issue #7376: instead of running a self-test (which was failing) when called
1229 with no arguments, doctest.py now gives a usage message.
1230
R. David Murrayef1992b2009-12-16 15:19:27 +00001231- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.

1235
R. David Murrayba311052009-12-04 00:09:14 +00001236- Issue #7431: use TESTFN in test_linecache instead of trying to create a
1237 file in the Lib/test directory, which might be read-only for the
1238 user running the tests.
1239
R. David Murray35768ad2009-11-15 00:23:21 +00001240- Issue #7324: add a sanity check to regrtest argument parsing to
1241 catch the case of an option with no handler.
1242
R. David Murray7dc72cc2009-11-14 16:13:02 +00001243- Issue #7312: Add a -F flag to run the selected tests in a loop until
1244 a test fails. Can be combined with -j.
1245
Antoine Pitrou060cee22009-11-13 16:29:04 +00001246- Issue #6551: test_zipimport could import and then destroy some modules of
1247 the encodings package, which would make other tests fail further down
1248 the road because the internally cached encoders and decoders would point
1249 to empty global variables.
1250
Antoine Pitrou941ee882009-11-11 20:59:38 +00001251- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1255
Brett Cannoncfed0292009-11-05 01:26:57 +00001256- Issue #7248 (part 2): Use a unique temporary directory for importlib source
1257 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1258 between concurrent executions on the same system.
1259
Brett Cannon0ae45112009-11-05 01:17:22 +00001260- Issue #7248: In importlib.test.source.util a try/finally block did not make
1261 sure that some referenced objects actually were created in the block before
1262 calling methods on the object.
1263
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001264- Issue #7222: Make thread "reaping" more reliable so that reference
1265 leak-chasing test runs give sensible results. The previous method of
1266 reaping threads could return successfully while some Thread objects were
1267 still referenced. This also introduces a new private function:
1268 :func:`_thread._count()`.
1269
R. David Murray27144602009-10-19 15:26:16 +00001270- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1271 longer runs the risk of causing the worker thread to fail.
1272
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001273- Issue #7055: test___all__ now greedily detects all modules which have an
1274 __all__ attribute, rather than using a hardcoded and incomplete list.
1275
R. David Murray0bc11ae2009-10-18 22:18:17 +00001276- Issue #7058: Added save/restore for things like sys.argv and cwd to
1277 runtest_inner in regrtest, with warnings if the called test modifies them,
1278 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001279
Mark Dickinson2e304402009-10-04 18:43:54 +00001280- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1281
Brett Cannon3c273842009-07-20 00:14:29 +00001282- Fixed tests in importlib.test.source.test_abc_loader that were masking
1283 the proper exceptions that should be raised for missing or improper code
1284 object bytecode.
1285
Brett Cannonb49c70c2009-07-15 04:08:33 +00001286- Removed importlib's custom test discovery code and switched to
1287 unittest.TestLoader.discover().

1290-----------
1291
1292- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were

1500
Antoine Pitroue4501852009-05-14 18:55:55 +00001501- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1502 library. This means, for example, that opening an UTF-16 text file in
1503 append mode doesn't add a BOM at the end of the file if the file isn't
1504 empty.
1505
R. David Murray74b89242009-05-13 17:33:03 +00001506- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1507 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1508 corrects a pydoc regression.
1509
R. David Murray99352742009-05-07 18:24:38 +00001510- Issue 5955: aifc's close method did not close the file it wrapped,
1511 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001553
1554Core and Builtins
1555-----------------
1556
Mark Dickinson865e01a2009-05-07 16:37:01 +00001557- Issue #5914: Add new C API function PyOS_string_to_double, and
1558 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1559
Eric Smith741191f2009-05-06 13:08:15 +00001560- Issue #3382: float.__format__, complex.__format__, and %-formatting
1561 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1562 affects nan -> NAN and inf -> INF.
1563
Mark Hammond5a607a32009-05-06 08:04:54 +00001564- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1565 in all operations, including splitdrive, split, etc. splitunc() now issues
1566 a PendingDeprecation warning.
1567
Eric Smith63376222009-05-05 14:04:18 +00001568- Issue #5920: For float.__format__, change the behavior with the
1569 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1570 to be like 'g' but with at least one decimal point and with a
1571 default precision of 12. Previously, the behavior the same but with
1572 a default precision of 6. This more closely matches str(), and
1573 reduces surprises when adding alignment flags to the empty
1574 presentation type. This also affects the new complex.__format__ in
1575 the same way.
1576
Martin v. Löwis011e8422009-05-05 04:43:17 +00001577- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1578
R. David Murrayb18500d2009-05-04 22:59:07 +00001579- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1580 shadowed by classtype's, even if it was None. property now
1581 inserts the __doc__ into the subclass instance __dict__.
1582
Antoine Pitrou244651a2009-05-04 18:56:13 +00001583- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1584 sequences. Patch by Nick Barnes and Victor Stinner.
1585
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001586- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001587
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001588- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1589 received a new method, detach(). detach() disconnects the underlying stream
1590 from the buffer or text IO and returns it.
1591
Mark Dickinson33841c32009-05-01 15:37:04 +00001592- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1593 floats with absolute value over 1e50. Also remove length
1594 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1595 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001596
Eric Smith741191f2009-05-06 13:08:15 +00001597- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001598 format(complex(1, 2./3), '.5') now produces a sensible result.
1599
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001600- Issue #5864: Fix empty format code formatting for floats so that it
1601 never gives more than the requested number of significant digits.
1602
Eric Smith6dc46f52009-04-27 20:39:49 +00001603- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1604 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1605
Eric Smithcc32a112009-04-26 21:35:14 +00001606- Issue #5835: Deprecate PyOS_ascii_formatd.
1607
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001608- Issue #4971: Fix titlecase for characters that are their own
1609 titlecase, but not their own uppercase.
1610
Benjamin Peterson193152c2009-04-25 01:08:45 +00001611- Issue #5283: Setting __class__ in __del__ caused a segfault.
1612
Mark Dickinsonad476da2009-04-23 19:14:16 +00001613- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1614 z involves nans, infs or negative zeros.
1615
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001616- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001617
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001618- Issue #1869 (and many duplicates): make round(x, n) correctly
1619 rounded for a float x, by using the decimal <-> binary conversions
1620 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1621 consistently agrees with format(x, '.2f').
1622
Benjamin Petersonae937c02009-04-18 20:54:08 +00001623- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1624 some builtin types.
1625
Eric Smith0923d1d2009-04-16 20:16:10 +00001626- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1627
Eric Smith35e84722009-04-16 20:21:28 +00001628- Issue #5515: str.format() type 'n' combined with commas and leading
1629 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001630
1631- Implement PEP 378, Format Specifier for Thousands Separator, for
1632 floats.
1633
Mark Dickinson3370cce2009-04-17 22:40:53 +00001634- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001635 1e11, not 1e12. This avoids printing 13 significant digits in
1636 situations where only 12 of them are correct. Example problem
1637 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1638 long time.)
1639
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001640- Issue #1580: On most platforms, use a 'short' float repr: for a
1641 finite float x, repr(x) now outputs a string based on the shortest
1642 sequence of decimal digits that rounds to x. Previous behaviour was
1643 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001644 Another minor difference is that the new repr switches to
1645 exponential notation at 1e16 instead of the previous 1e17; this
1646 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001647
1648 There's a new sys attribute sys.float_repr_style, which takes
1649 the value 'short' to indicate that we're using short float repr,
1650 and 'legacy' if the short float repr isn't available for one
1651 reason or another.
1652
1653 The float repr change involves incorporating David Gay's 'perfect
1654 rounding' code into the Python core (it's in Python/dtoa.c). As a
1655 secondary consequence, all string-to-float and float-to-string
1656 conversions (including all float formatting operations) will be
1657 correctly rounded on these platforms.
1658
1659 See issue 1580 discussions for details of platforms for which
1660 this change does not apply.
1661
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001662- Issue #5759: float() didn't call __float__ on str subclasses.
1663
Georg Brandlabc38772009-04-12 15:51:51 +00001664- The string.maketrans() function is deprecated; there is a new static method
1665 maketrans() on the bytes and bytearray classes. This removes confusion about
1666 the types string.maketrans() is supposed to work with, and mirrors the
1667 methods available on the str class.
1668
R. David Murraydc6da8a2009-04-09 22:16:43 +00001669- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1670 its clarity and its speed.
1671
Matthias Klose091c7b12009-04-07 13:24:27 +00001672- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1673 to avoid compiler warnings.
1674
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001675- Issue #3739: The unicode-internal encoder now reports the number of characters
1676 consumed like any other encoder (instead of the number of bytes).

1812
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001813- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1814 byte, and the 'C' code only accepts a unicode character.
1815
Georg Brandl406b3d82009-04-11 21:24:37 +00001816- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

1818
Brett Cannon0759dd62009-04-01 18:13:07 +00001819- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1820
Georg Brandlab6f2f62009-03-31 04:16:10 +00001821- Fix a segfault when running test_exceptions with coverage, caused by
1822 insufficient checks in accessors of Exception.__context__.
1823
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001824- Issue #5604: non-ASCII characters in module name passed to
1825 imp.find_module() were converted to UTF-8 while the path is
1826 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00001828- Issue #5126: str.isprintable() returned False for space characters.
1829
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001830- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1831 the end sys.path, for compatibility with the system install of Python.
1832
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001833- Issue #4688: Add a heuristic so that tuples and dicts containing only
1834 untrackable objects are not tracked by the garbage collector. This can
1835 reduce the size of collections and therefore the garbage collection overhead
1836 on long-running programs, depending on their particular use of datatypes.
1837
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001838- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1843 2**15 for the internal representation of integers, for performance
1844 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1845 --enable-big-digits option to configure, which overrides the
1846 default. Add sys.int_info structseq to provide information about
1847 the internal format.

1850 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1851 and sizeof(Py_UNICODE) == 2.
1852
Eric Smith8ec90442009-03-14 12:29:34 +00001853- Issue #5237: Allow auto-numbered fields in str.format(). For

1855
Antoine Pitrou652e7072009-03-13 19:25:20 +00001856- Issue #5392: when a very low recursion limit was set, the interpreter would
1857 abort with a fatal error after the recursion limit was hit twice.
1858
Matthias Klose042f1332009-04-04 14:32:42 +00001859- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1890
Brett Cannon7f6b4f82009-03-30 21:30:26 +00001891- Issue #5236: Change time.strptime() to only take strings. Didn't work with
1892 bytes already but the failure was non-obvious.
1893
Jesse Noller7af4ef82009-03-30 16:47:15 +00001894- Issue #5177: Multiprocessing's SocketListener class now uses

1905
Lars Gustäbel42e00912009-03-22 20:34:29 +00001906- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1907 forever on incomplete input. That caused tarfile.open() to hang when used
1908 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1909 partial bzip2 compressed data.
1910
Mark Dickinson79f52032009-03-17 23:12:51 +00001911- Issue #2110: Add support for thousands separator and 'n' type

1979 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1980 evaluation loop is compiled with a new dispatch mechanism which gives
1981 speedups of up to 20%, depending on the system, on various benchmarks.

1997 to str, bytes and bytearray could be optimized away by the compiler, letting
1998 the interpreter segfault instead of raising an error.
1999
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002000- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2026 flag to work properly. Furthermore, when specifying -u, the text stdout
2027 and stderr streams have line-by-line buffering enabled (the default being
2028 to buffer arbitrary chunks of data).
2029
Raymond Hettinger35631532009-01-09 03:58:09 +00002030- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

2033
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002034- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2035 an existing .py counterpart, override the co_filename attributes of all
2036 code objects if the original filename is obsolete (which can happen if the
2037 file has been renamed, moved, or if it is accessed through different paths).
2038 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2039
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002040- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2041 one byte. Also fixes the meaning of len() so that it returns the number of
2042 items, rather than the size in bytes.
2043
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002044- Issue #4075: Use OutputDebugStringW in Py_FatalError.

2057
Georg Brandlccc47b62008-12-28 11:44:14 +00002058- Issue #4759: None is now allowed as the first argument of

2110 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2111 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2112 of using the replace error handler in PyUnicode_DecodeUTF8().

2433 do an explicit seek to the end of file (so that e.g. tell() returns the

2718 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2719 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2720 skip the tests if DISPLAY is defined but can't be used.
2721
R. David Murraya21e4ca2009-03-31 23:16:50 +00002722- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002723 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002724 from test support, which does the conversion.
