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.

Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000342- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
343 It should correctly return an empty response now.
344
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000345- Issue #8546: Reject None given as the buffering argument to _pyio.open.
346
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000347- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
348 Sridhar Ratnakumar.

351 and mappings.
352
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000353- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
354 where the method could block indefinitely if called just before the
355 event loop started running. This also fixes the occasional freezes
356 witnessed in test_httpservers.
357
Antoine Pitrou40f08742010-04-24 22:04:40 +0000358- Issue #8524: When creating an SSL socket, the timeout value of the
359 original socket wasn't retained (instead, a socket with a positive timeout
360 would be turned into a non-blocking SSL socket).
361
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000362- Issue #5103: SSL handshake would ignore the socket timeout and block
363 indefinitely if the other end didn't respond.
364
365- The do_handshake() method of SSL objects now adjusts the blocking mode of
366 the SSL structure if necessary (as other methods already do).
367
Victor Stinner13bb71c2010-04-23 21:41:56 +0000368- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
369 and bytes strings for environment keys and values
370

373 message
374
Victor Stinner349fd522010-04-23 10:56:17 +0000375- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
376
Sean Reifscheider13daf122010-04-23 09:29:52 +0000377- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
378 the string "python" as the *ident*. openlog() arguments are all optional
379 and keywords.
380
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000381- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
382 a non-infinite timeout. Also make that method friendlier with applications
383 wanting to continue using the socket in clear-text mode, by disabling
384 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
385
Antoine Pitrou7062db82010-04-22 13:30:10 +0000386- Issue #8496: make mailcap.lookup() always return a list, rather than an
387 iterator. Patch by Gregory Nofi.
388
Victor Stinner35466c52010-04-22 11:23:23 +0000389- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
390 collation name contains a surrogate character.
391
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000392- Issue #8484: Load all ciphers and digest algorithms when initializing
393 the _ssl extension, such that verification of some SSL certificates
394 doesn't fail because of an "unknown algorithm".
395
Tarek Ziadéfb437512010-04-20 08:57:33 +0000396- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
397
Tarek Ziadé5340db32010-04-19 22:30:51 +0000398- Issue #1540112: Now allowing the choice of a copy function in
399 shutil.copytree.
400
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000401- Issue #4814: timeout parameter is now applied also for connections resulting
402 from PORT/EPRT commands.
403
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000404- Issue #8463: added missing reference to bztar in shutil's documentation.
405
Ronald Oussoren84151202010-04-18 20:46:11 +0000406- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
407 (as long as the user didn't specify 'automatic proxy configuration').
408
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000409- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
410 code as stated in RFC-959 at chapter 5.4.
411
Victor Stinner738446f02010-04-18 00:00:44 +0000412- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
413 surrogates.
414
Antoine Pitrou0454af92010-04-17 23:51:58 +0000415- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000416 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

428 surrogates.
429
Senthil Kumaranad02d232010-04-16 03:02:13 +0000430- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
431 Locke and Hans Ulrich Niedermann.
432
R. David Murrayd48739f2010-04-14 18:59:18 +0000433- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
434
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000435- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
436 module now takes an optional timeout argument in seconds. Timeout support
437 relies on the system threading library, so as to avoid a semi-busy wait
438 loop.
439
Victor Stinner485fb562010-04-13 11:07:24 +0000440- Issue #8383: pickle and pickletools use surrogatepass error handler when
441 encoding unicode as utf8 to support lone surrogates and stay compatible with
442 Python 2.x and 3.0
443
R. David Murrayb2416e52010-04-12 16:58:02 +0000444- Issue #7585: difflib context and unified diffs now place a tab between
445 filename and date, conforming to the 'standards' they were originally
446 designed to follow. This improves compatibility with patch tools.
447
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000448- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
449 character sets will now consistently use a Content-Transfer-Encoding of
450 7bit rather than sometimes being marked as 8bit.
451
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000452- Issue #8375: test_distutils now checks if the temporary directory are still
453 present before it cleans them.
454
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000455- Issue #8374: Update the internal alias table in the :mod:`locale` module
456 to cover recent locale changes and additions.
457
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000458- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
459 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
460 and `ssl.OPENSSL_VERSION_NUMBER`.
461
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000462- Add functools.total_ordering() and functools.cmp_to_key().
463
Mark Dickinson089b00c2010-04-03 15:51:03 +0000464- Issue #8257: The Decimal construct now accepts a float instance
465 directly, converting that float to a Decimal of equal value:
466
467 >>> Decimal(1.1)
468 Decimal('1.100000000000000088817841970012523233890533447265625')
469
Mark Dickinson98127c32010-04-03 11:18:52 +0000470- Issue #8294: The Fraction constructor now accepts Decimal and float
471 instances directly.
472
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000473- Issue #7279: Comparisons involving a Decimal signaling NaN now
474 signal InvalidOperation instead of returning False. (Comparisons
475 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
476 are now hashable; Decimal signaling NaNs remain unhashable.
477
478- Issue #2531: Comparison operations between floats and Decimal
479 instances now return a result based on the numeric values of the
480 operands; previously they returned an arbitrary result based on
481 the relative ordering of id(float) and id(Decimal).
482
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000483- Added a subtract() method to collections.Counter().
484
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000485- Issue #8233: When run as a script, py_compile.py optionally takes a single
486 argument `-` which tells it to read files to compile from stdin. Each line
487 is read on demand and the named file is compiled immediately. (Original
488 patch by Piotr Ożarowski).
489
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000490- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
491 form feed (0x0C) are now considered linebreaks, as specified in Unicode
492 Standard Annex #14. See issue #7643.
493 http://www.unicode.org/reports/tr14/
494
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000495- Comparisons using one of <, <=, >, >= between a complex instance and
496 a Fractions instance now raise TypeError instead of returning
497 True/False. This makes Fraction <=> complex comparisons consistent with
498 int <=> complex, float <=> complex, and complex <=> complex comparisons.
499
Antoine Pitrou39b35432010-03-23 00:25:54 +0000500- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
501 some methods (such as oss_mixer_device.fileno()) were not available.
502 Initial patch by Bertrand Janin.
503
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000504- Issue #8205: Remove the "Modules" directory from sys.path when Python is
505 running from the build directory (POSIX only).
506
Antoine Pitrou910bd512010-03-22 20:11:09 +0000507- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
508 didn't support chflags() (for example ZFS under FreeBSD). The error is
509 now silenced.
510
R. David Murrayca2edce2010-03-22 17:48:48 +0000511- Issue #7860: platform.uname now reports the correct 'machine' type
512 when Python is running in WOW64 mode on 64 bit Windows.
513
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000514- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
515 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
516 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000517
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000518- Issue #4282: Fix the main function of the profile module for a non-ASCII
519 script, open the file in binary mode and not in text mode with the default
520 (utf8) encoding.
521
Florent Xicluna54467e02010-03-21 12:29:50 +0000522- Issue #8179: Fix macpath.realpath() on a non-existing path.
523
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000524- Issue #8024: Update the Unicode database to 5.2.
525

527
Benjamin Peterson689a5582010-03-18 22:29:52 +0000528- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
529 detected.
530
Martin v. Löwis4b003072010-03-16 13:19:21 +0000531- Issue #6716/2: Backslash-replace error output in compilall.
532
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000533- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
534 with Tcl/Tk-8.5.
535
Matthias Klosec33b9022010-03-16 00:36:26 +0000536- Issue #8140: extend compileall to compile single files. Add -i option.

539 the locale.
540
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000541- The internals of the subprocess module on POSIX systems have been replaced
542 by an extension module (_posixsubprocess) so that the fork()+exec() can be
543 done safely without the possibility of deadlock in multithreaded applications.
544
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000545- subprocess.Popen now has restore_signals and start_new_session features.
546 The default of restore_signals=True is a new behavior compared to earlier
547 Python versions. This means that signals such as SIGPIPE are not ignored
548 by default in subprocesses launched by Python (Issue #1652).
549
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000550- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
551 cElementTree module is updated too.

560 the replacement were all bytes. Patch by Antoine Pitrou.
561
Gerhard Häringf9cee222010-03-05 15:20:03 +0000562- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
563 bugs and allows loading SQLite extensions from shared libraries.

Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +0000595- Issue #6666: fix bug in trace.py that applied the list of directories
596 to be ignored only to the first file. Noted by Bogdan Opanchuk.
597
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000598- Issue #7597: curses.use_env() can now be called before initscr().
599 Noted by Kan-Ru Chen.
600
Ezio Melotti19e4acf2010-02-22 15:59:01 +0000601- Issue #7310: fix the __repr__ of os.environ to show the environment variables.

607 bytecode file when it was less then 8 bytes.
608
Mark Dickinson84230a12010-02-18 14:49:50 +0000609- Issue #7633: In the decimal module, Context class methods (with the
610 exception of canonical and is_canonical) now accept instances of int
611 and long wherever a Decimal instance is accepted, and implicitly
612 convert that argument to Decimal. Previously only some arguments
613 were converted.
614
R. David Murray1f449142010-02-11 00:15:05 +0000615- Issue #7835: shelve should no longer produce mysterious warnings during

Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000618- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
619 in XML processing instructions and comments. These raw characters are
620 allowed by the XML specification, and are necessary when outputting e.g.
621 PHP code in a processing instruction. Patch by Neil Muller.

634
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000635- Issue #6939: Fix file I/O objects in the `io` module to keep the original
636 file position when calling `truncate()`. It would previously change the
637 file position to the given argument, which goes against the tradition of
638 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
639
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000640- Issue #7610: Reworked implementation of the internal
641 :class:`zipfile.ZipExtFile` class used to represent files stored inside
642 an archive. The new implementation is significantly faster and can
643 be wrapped in a :class:`io.BufferedReader` object for more speedups.
644 It also solves an issue where interleaved calls to `read()` and
645 `readline()` give wrong results. Patch by Nir Aides.
646
Jesse Noller1f0b6582010-01-27 03:36:01 +0000647- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

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

807
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000808- Issue #6816: runpy now provides a run_path function that allows Python code
809 to execute file paths that refer to source or compiled Python files as well
810 as zipfiles, directories and other valid sys.path entries that contain a
811 __main__.py file. This allows applications that run other Python scripts to
812 support the same flexibility as the CPython command line itself.
813
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000814- Issue #7318: multiprocessing now uses a timeout when it fails to establish

850 failures on systems with slightly bogus mtime behaviour.
851
Gregory P. Smith50467882009-11-01 18:42:17 +0000852- Issue #7246 & Issue #7208: getpass now properly flushes input before
853 reading from stdin so that existing input does not confuse it and

Florent Xiclunab14930c2010-03-13 15:26:44 +00001206- Issue #7849: Now the utility ``check_warnings`` verifies if the warnings are
1207 effectively raised.
1208
Florent Xiclunac9c79782010-03-08 12:24:53 +00001209- The four path modules (genericpath, macpath, ntpath, posixpath) share a

1220
Ezio Melotti184bdfb2010-02-18 09:37:05 +00001221- Issue #7712: test.support gained a new `temp_cwd` context manager which is
1222 now also used by regrtest to run all the tests in a temporary directory.
1223 The original CWD is saved in `support.SAVEDCWD`.
1224 Thanks to Florent Xicluna who helped with the patch.

1229
Florent Xicluna3f88c0e2010-03-19 14:40:31 +00001230- Issue #7728: test_timeout was changed to use support.bind_port instead of a
1231 hard coded port.
R. David Murraye9e95932010-02-06 05:00:15 +00001232
R. David Murray445448c2009-12-20 17:28:31 +00001233- Issue #7376: instead of running a self-test (which was failing) when called
1234 with no arguments, doctest.py now gives a usage message.

1240
R. David Murrayba311052009-12-04 00:09:14 +00001241- Issue #7431: use TESTFN in test_linecache instead of trying to create a
1242 file in the Lib/test directory, which might be read-only for the
1243 user running the tests.
1244
R. David Murray35768ad2009-11-15 00:23:21 +00001245- Issue #7324: add a sanity check to regrtest argument parsing to
1246 catch the case of an option with no handler.
1247
R. David Murray7dc72cc2009-11-14 16:13:02 +00001248- Issue #7312: Add a -F flag to run the selected tests in a loop until
1249 a test fails. Can be combined with -j.
1250
Antoine Pitrou060cee22009-11-13 16:29:04 +00001251- Issue #6551: test_zipimport could import and then destroy some modules of
1252 the encodings package, which would make other tests fail further down
1253 the road because the internally cached encoders and decoders would point
1254 to empty global variables.
1255
Antoine Pitrou941ee882009-11-11 20:59:38 +00001256- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1260
Brett Cannoncfed0292009-11-05 01:26:57 +00001261- Issue #7248 (part 2): Use a unique temporary directory for importlib source
1262 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1263 between concurrent executions on the same system.
1264
Brett Cannon0ae45112009-11-05 01:17:22 +00001265- Issue #7248: In importlib.test.source.util a try/finally block did not make
1266 sure that some referenced objects actually were created in the block before
1267 calling methods on the object.
1268
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001269- Issue #7222: Make thread "reaping" more reliable so that reference
1270 leak-chasing test runs give sensible results. The previous method of
1271 reaping threads could return successfully while some Thread objects were
1272 still referenced. This also introduces a new private function:
1273 :func:`_thread._count()`.
1274
R. David Murray27144602009-10-19 15:26:16 +00001275- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1276 longer runs the risk of causing the worker thread to fail.
1277
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001278- Issue #7055: test___all__ now greedily detects all modules which have an
1279 __all__ attribute, rather than using a hardcoded and incomplete list.
1280
R. David Murray0bc11ae2009-10-18 22:18:17 +00001281- Issue #7058: Added save/restore for things like sys.argv and cwd to
1282 runtest_inner in regrtest, with warnings if the called test modifies them,
1283 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001284
Mark Dickinson2e304402009-10-04 18:43:54 +00001285- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1286
Brett Cannon3c273842009-07-20 00:14:29 +00001287- Fixed tests in importlib.test.source.test_abc_loader that were masking
1288 the proper exceptions that should be raised for missing or improper code
1289 object bytecode.
1290
Brett Cannonb49c70c2009-07-15 04:08:33 +00001291- Removed importlib's custom test discovery code and switched to
1292 unittest.TestLoader.discover().

1295-----------
1296
1297- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were

1505
Antoine Pitroue4501852009-05-14 18:55:55 +00001506- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1507 library. This means, for example, that opening an UTF-16 text file in
1508 append mode doesn't add a BOM at the end of the file if the file isn't
1509 empty.
1510
R. David Murray74b89242009-05-13 17:33:03 +00001511- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1512 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1513 corrects a pydoc regression.
1514
R. David Murray99352742009-05-07 18:24:38 +00001515- Issue 5955: aifc's close method did not close the file it wrapped,
1516 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001558
1559Core and Builtins
1560-----------------
1561
Mark Dickinson865e01a2009-05-07 16:37:01 +00001562- Issue #5914: Add new C API function PyOS_string_to_double, and
1563 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1564
Eric Smith741191f2009-05-06 13:08:15 +00001565- Issue #3382: float.__format__, complex.__format__, and %-formatting
1566 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1567 affects nan -> NAN and inf -> INF.
1568
Mark Hammond5a607a32009-05-06 08:04:54 +00001569- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1570 in all operations, including splitdrive, split, etc. splitunc() now issues
1571 a PendingDeprecation warning.
1572
Eric Smith63376222009-05-05 14:04:18 +00001573- Issue #5920: For float.__format__, change the behavior with the
1574 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1575 to be like 'g' but with at least one decimal point and with a
1576 default precision of 12. Previously, the behavior the same but with
1577 a default precision of 6. This more closely matches str(), and
1578 reduces surprises when adding alignment flags to the empty
1579 presentation type. This also affects the new complex.__format__ in
1580 the same way.
1581
Martin v. Löwis011e8422009-05-05 04:43:17 +00001582- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1583
R. David Murrayb18500d2009-05-04 22:59:07 +00001584- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1585 shadowed by classtype's, even if it was None. property now
1586 inserts the __doc__ into the subclass instance __dict__.
1587
Antoine Pitrou244651a2009-05-04 18:56:13 +00001588- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1589 sequences. Patch by Nick Barnes and Victor Stinner.
1590
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001591- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001592
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001593- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1594 received a new method, detach(). detach() disconnects the underlying stream
1595 from the buffer or text IO and returns it.
1596
Mark Dickinson33841c32009-05-01 15:37:04 +00001597- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1598 floats with absolute value over 1e50. Also remove length
1599 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1600 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001601
Eric Smith741191f2009-05-06 13:08:15 +00001602- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001603 format(complex(1, 2./3), '.5') now produces a sensible result.
1604
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001605- Issue #5864: Fix empty format code formatting for floats so that it
1606 never gives more than the requested number of significant digits.
1607
Eric Smith6dc46f52009-04-27 20:39:49 +00001608- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1609 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1610
Eric Smithcc32a112009-04-26 21:35:14 +00001611- Issue #5835: Deprecate PyOS_ascii_formatd.
1612
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001613- Issue #4971: Fix titlecase for characters that are their own
1614 titlecase, but not their own uppercase.
1615
Benjamin Peterson193152c2009-04-25 01:08:45 +00001616- Issue #5283: Setting __class__ in __del__ caused a segfault.
1617
Mark Dickinsonad476da2009-04-23 19:14:16 +00001618- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1619 z involves nans, infs or negative zeros.
1620
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001621- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001622
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001623- Issue #1869 (and many duplicates): make round(x, n) correctly
1624 rounded for a float x, by using the decimal <-> binary conversions
1625 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1626 consistently agrees with format(x, '.2f').
1627
Benjamin Petersonae937c02009-04-18 20:54:08 +00001628- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1629 some builtin types.
1630
Eric Smith0923d1d2009-04-16 20:16:10 +00001631- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1632
Eric Smith35e84722009-04-16 20:21:28 +00001633- Issue #5515: str.format() type 'n' combined with commas and leading
1634 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001635
1636- Implement PEP 378, Format Specifier for Thousands Separator, for
1637 floats.
1638
Mark Dickinson3370cce2009-04-17 22:40:53 +00001639- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001640 1e11, not 1e12. This avoids printing 13 significant digits in
1641 situations where only 12 of them are correct. Example problem
1642 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1643 long time.)
1644
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001645- Issue #1580: On most platforms, use a 'short' float repr: for a
1646 finite float x, repr(x) now outputs a string based on the shortest
1647 sequence of decimal digits that rounds to x. Previous behaviour was
1648 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001649 Another minor difference is that the new repr switches to
1650 exponential notation at 1e16 instead of the previous 1e17; this
1651 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001652
1653 There's a new sys attribute sys.float_repr_style, which takes
1654 the value 'short' to indicate that we're using short float repr,
1655 and 'legacy' if the short float repr isn't available for one
1656 reason or another.
1657
1658 The float repr change involves incorporating David Gay's 'perfect
1659 rounding' code into the Python core (it's in Python/dtoa.c). As a
1660 secondary consequence, all string-to-float and float-to-string
1661 conversions (including all float formatting operations) will be
1662 correctly rounded on these platforms.
1663
1664 See issue 1580 discussions for details of platforms for which
1665 this change does not apply.
1666
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001667- Issue #5759: float() didn't call __float__ on str subclasses.
1668
Georg Brandlabc38772009-04-12 15:51:51 +00001669- The string.maketrans() function is deprecated; there is a new static method
1670 maketrans() on the bytes and bytearray classes. This removes confusion about
1671 the types string.maketrans() is supposed to work with, and mirrors the
1672 methods available on the str class.
1673
R. David Murraydc6da8a2009-04-09 22:16:43 +00001674- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1675 its clarity and its speed.
1676
Matthias Klose091c7b12009-04-07 13:24:27 +00001677- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1678 to avoid compiler warnings.
1679
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001680- Issue #3739: The unicode-internal encoder now reports the number of characters
1681 consumed like any other encoder (instead of the number of bytes).

1817
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001818- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1819 byte, and the 'C' code only accepts a unicode character.
1820
Georg Brandl406b3d82009-04-11 21:24:37 +00001821- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1822 when hitting the recursion limit under certain circumstances.
1823
Brett Cannon0759dd62009-04-01 18:13:07 +00001824- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1825
Georg Brandlab6f2f62009-03-31 04:16:10 +00001826- Fix a segfault when running test_exceptions with coverage, caused by
1827 insufficient checks in accessors of Exception.__context__.
1828
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001829- Issue #5604: non-ASCII characters in module name passed to
1830 imp.find_module() were converted to UTF-8 while the path is
1831 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00001833- Issue #5126: str.isprintable() returned False for space characters.
1834
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001835- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1836 the end sys.path, for compatibility with the system install of Python.
1837
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001838- Issue #4688: Add a heuristic so that tuples and dicts containing only
1839 untrackable objects are not tracked by the garbage collector. This can
1840 reduce the size of collections and therefore the garbage collection overhead
1841 on long-running programs, depending on their particular use of datatypes.
1842
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001843- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1855 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1856 and sizeof(Py_UNICODE) == 2.
1857
Eric Smith8ec90442009-03-14 12:29:34 +00001858- Issue #5237: Allow auto-numbered fields in str.format(). For

1860
Antoine Pitrou652e7072009-03-13 19:25:20 +00001861- Issue #5392: when a very low recursion limit was set, the interpreter would
1862 abort with a fatal error after the recursion limit was hit twice.
1863
Matthias Klose042f1332009-04-04 14:32:42 +00001864- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1874 error substitutions from non-strict codec error callbacks in
1875 incrementalencoder and StreamWriter.
1876
Georg Brandl33c28812009-04-01 23:07:29 +00001877- Issue #5656: Fix the coverage reporting when running the test suite with

1907
Benjamin Peterson59406a92009-03-26 17:10:29 +00001908- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1909 io.BufferedRandom have been deprecated for removal in Python 3.2.
1910
Lars Gustäbel42e00912009-03-22 20:34:29 +00001911- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1912 forever on incomplete input. That caused tarfile.open() to hang when used
1913 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1914 partial bzip2 compressed data.
1915
Mark Dickinson79f52032009-03-17 23:12:51 +00001916- Issue #2110: Add support for thousands separator and 'n' type

1984 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1985 evaluation loop is compiled with a new dispatch mechanism which gives
1986 speedups of up to 20%, depending on the system, on various benchmarks.

2002 to str, bytes and bytearray could be optimized away by the compiler, letting
2003 the interpreter segfault instead of raising an error.
2004
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002005- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2029
Antoine Pitrou05608432009-01-09 18:53:14 +00002030- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2031 flag to work properly. Furthermore, when specifying -u, the text stdout
2032 and stderr streams have line-by-line buffering enabled (the default being
2033 to buffer arbitrary chunks of data).
2034
Raymond Hettinger35631532009-01-09 03:58:09 +00002035- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2036 instead of ints (reducing its size from 4 to 8 times thereby reducing
2037 Python's overall memory).
2038
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002039- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2040 an existing .py counterpart, override the co_filename attributes of all
2041 code objects if the original filename is obsolete (which can happen if the
2042 file has been renamed, moved, or if it is accessed through different paths).
2043 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2044
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002045- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2046 one byte. Also fixes the meaning of len() so that it returns the number of
2047 items, rather than the size in bytes.
2048
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002049- Issue #4075: Use OutputDebugStringW in Py_FatalError.

2062
Georg Brandlccc47b62008-12-28 11:44:14 +00002063- Issue #4759: None is now allowed as the first argument of

2117 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00002437- Issue #5008: When a file is opened in append mode with the new IO library,
2438 do an explicit seek to the end of file (so that e.g. tell() returns the

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002728 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002729 from test support, which does the conversion.
