84
Mark Dickinsonbc099642010-01-29 17:27:24 +000085- Issue #7788: Fix an interpreter crash produced by deleting a list
86 slice with very large step value.
87
Eric Smithf7bb5782010-01-27 00:44:57 +000088- Issue #7766: Change sys.getwindowsversion() return value to a named
89 tuple and add the additional members returned in an OSVERSIONINFOEX
90 structure. The new members are service_pack_major, service_pack_minor,
91 suite_mask, and product_type.
92
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000093- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
94 could crash in many places because of the PyByteArray_AS_STRING() macro
95 returning NULL. The macro now returns a statically allocated empty
96 string instead.
97
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000098- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
99 where the right hand operand is a set of constants, by turning the set into
100 a frozenset and pre-building it as a constant. The comparison operation
101 is made against the constant instead of building a new set each time it is
102 executed (a similar optimization already existed which turned a list of
103 constants into a pre-built tuple). Patch and additional tests by Dave
104 Malcolm.
105
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000106- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

111 alpha 2, including: (1) a serious 'wrong output' bug that could
112 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
113 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000114 strings corresponding to subnormal values, (3) a memory leak for
115 some values large enough to cause overflow, and (4) a number of
116 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000117
Benjamin Petersonaea44282010-01-04 01:10:28 +0000118- The __complex__ method is now looked up on the class of instances to make it

128 negative zero) in ** operator. The behaviour now conforms to that
129 described in C99 Annex F.
130
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000131- Issue #1811: improve accuracy and cross-platform consistency for
132 true division of integers: the result of a/b is now correctly
133 rounded for ints a and b (at least on IEEE 754 platforms), and in
134 particular does not depend on the internal representation of an int.
135
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000136- Issue #6834: replace the implementation for the 'python' and 'pythonw'
137 executables on OSX.
138
139 These executables now work properly with the arch(1) command:
140 ``arch -ppc python`` will start a universal binary version of python
141 in PPC mode (unlike previous releases).
142
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000143- Issue #7466: segmentation fault when the garbage collector is called

159
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000160- Issue #7298: fixes for range and reversed(range(...)). Iteration
161 over range(a, b, c) incorrectly gave an empty iterator when a, b and
162 c fit in C long but the length of the range did not. Also fix

314 pymalloc allocator will be automatically disabled when running under
315 Valgrind. This gives improved memory leak detection when running
316 under Valgrind, while taking advantage of pymalloc at other times.

Ronald Oussoren84151202010-04-18 20:46:11 +0000321- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
322 (as long as the user didn't specify 'automatic proxy configuration').
323
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000324- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
325 code as stated in RFC-959 at chapter 5.4.
326
Victor Stinner738446f02010-04-18 00:00:44 +0000327- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
328 surrogates.
329
Antoine Pitrou0454af92010-04-17 23:51:58 +0000330- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000331 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

335
Victor Stinner0e59cc32010-04-16 23:49:32 +0000336- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
337 the current working directory.

349
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000350- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
351 module now takes an optional timeout argument in seconds. Timeout support
352 relies on the system threading library, so as to avoid a semi-busy wait
353 loop.
354
Victor Stinner485fb562010-04-13 11:07:24 +0000355- Issue #8383: pickle and pickletools use surrogatepass error handler when
356 encoding unicode as utf8 to support lone surrogates and stay compatible with
357 Python 2.x and 3.0
358
R. David Murrayb2416e52010-04-12 16:58:02 +0000359- Issue #7585: difflib context and unified diffs now place a tab between
360 filename and date, conforming to the 'standards' they were originally
361 designed to follow. This improves compatibility with patch tools.
362
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000363- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
364 character sets will now consistently use a Content-Transfer-Encoding of
365 7bit rather than sometimes being marked as 8bit.
366
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000367- Issue #8375: test_distutils now checks if the temporary directory are still

374 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
375 and `ssl.OPENSSL_VERSION_NUMBER`.
376
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000377- Add functools.total_ordering() and functools.cmp_to_key().
378
Mark Dickinson089b00c2010-04-03 15:51:03 +0000379- Issue #8257: The Decimal construct now accepts a float instance
380 directly, converting that float to a Decimal of equal value:
381
382 >>> Decimal(1.1)
383 Decimal('1.100000000000000088817841970012523233890533447265625')
384
Mark Dickinson98127c32010-04-03 11:18:52 +0000385- Issue #8294: The Fraction constructor now accepts Decimal and float
386 instances directly.
387
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000388- Issue #7279: Comparisons involving a Decimal signaling NaN now
389 signal InvalidOperation instead of returning False. (Comparisons
390 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
391 are now hashable; Decimal signaling NaNs remain unhashable.
392
393- Issue #2531: Comparison operations between floats and Decimal
394 instances now return a result based on the numeric values of the
395 operands; previously they returned an arbitrary result based on
396 the relative ordering of id(float) and id(Decimal).
397
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000398- Added a subtract() method to collections.Counter().
399
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000400- Issue #8233: When run as a script, py_compile.py optionally takes a single
401 argument `-` which tells it to read files to compile from stdin. Each line
402 is read on demand and the named file is compiled immediately. (Original
403 patch by Piotr Ożarowski).
404
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000405- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
406 form feed (0x0C) are now considered linebreaks, as specified in Unicode
407 Standard Annex #14. See issue #7643.
408 http://www.unicode.org/reports/tr14/
409
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000410- Comparisons using one of <, <=, >, >= between a complex instance and
411 a Fractions instance now raise TypeError instead of returning
412 True/False. This makes Fraction <=> complex comparisons consistent with
413 int <=> complex, float <=> complex, and complex <=> complex comparisons.
414
Antoine Pitrou39b35432010-03-23 00:25:54 +0000415- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
416 some methods (such as oss_mixer_device.fileno()) were not available.
417 Initial patch by Bertrand Janin.
418
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000419- Issue #8205: Remove the "Modules" directory from sys.path when Python is
420 running from the build directory (POSIX only).
421
Antoine Pitrou910bd512010-03-22 20:11:09 +0000422- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
423 didn't support chflags() (for example ZFS under FreeBSD). The error is
424 now silenced.
425
R. David Murrayca2edce2010-03-22 17:48:48 +0000426- Issue #7860: platform.uname now reports the correct 'machine' type
427 when Python is running in WOW64 mode on 64 bit Windows.
428
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000429- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
430 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
431 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000432
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000433- Issue #4282: Fix the main function of the profile module for a non-ASCII
434 script, open the file in binary mode and not in text mode with the default
435 (utf8) encoding.
436
Florent Xicluna54467e02010-03-21 12:29:50 +0000437- Issue #8179: Fix macpath.realpath() on a non-existing path.

442
Benjamin Peterson689a5582010-03-18 22:29:52 +0000443- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
444 detected.
445
Martin v. Löwis4b003072010-03-16 13:19:21 +0000446- Issue #6716/2: Backslash-replace error output in compilall.
447
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000448- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
449 with Tcl/Tk-8.5.
450
Matthias Klosec33b9022010-03-16 00:36:26 +0000451- Issue #8140: extend compileall to compile single files. Add -i option.

454 the locale.
455
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000456- The internals of the subprocess module on POSIX systems have been replaced
457 by an extension module (_posixsubprocess) so that the fork()+exec() can be
458 done safely without the possibility of deadlock in multithreaded applications.
459
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000460- subprocess.Popen now has restore_signals and start_new_session features.
461 The default of restore_signals=True is a new behavior compared to earlier
462 Python versions. This means that signals such as SIGPIPE are not ignored
463 by default in subprocesses launched by Python (Issue #1652).
464
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000465- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
466 cElementTree module is updated too.

475 the replacement were all bytes. Patch by Antoine Pitrou.
476
Gerhard Häringf9cee222010-03-05 15:20:03 +0000477- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
478 bugs and allows loading SQLite extensions from shared libraries.

493
Florent Xiclunac279ebf2010-02-27 11:31:21 +0000494- Issue #691291: codecs.open() should not convert end of lines on reading and
495 writing.
496
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000497- Issue #7869: logging: improved diagnostic for format-time errors.

511 to be ignored only to the first file. Noted by Bogdan Opanchuk.
512
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000513- Issue #7597: curses.use_env() can now be called before initscr().
514 Noted by Kan-Ru Chen.

522 bytecode file when it was less then 8 bytes.
523
Mark Dickinson84230a12010-02-18 14:49:50 +0000524- Issue #7633: In the decimal module, Context class methods (with the
525 exception of canonical and is_canonical) now accept instances of int
526 and long wherever a Decimal instance is accepted, and implicitly
527 convert that argument to Decimal. Previously only some arguments
528 were converted.
529
R. David Murray1f449142010-02-11 00:15:05 +0000530- Issue #7835: shelve should no longer produce mysterious warnings during
531 interpreter shutdown.
532
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000533- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
534 in XML processing instructions and comments. These raw characters are
535 allowed by the XML specification, and are necessary when outputting e.g.
536 PHP code in a processing instruction. Patch by Neil Muller.
537
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000538- Issue #6233: ElementTree failed converting unicode characters to XML

548 type is specified. Patch by Brian Curtin.
549
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000550- Issue #6939: Fix file I/O objects in the `io` module to keep the original
551 file position when calling `truncate()`. It would previously change the
552 file position to the given argument, which goes against the tradition of
553 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
554
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000555- Issue #7610: Reworked implementation of the internal
556 :class:`zipfile.ZipExtFile` class used to represent files stored inside
557 an archive. The new implementation is significantly faster and can
558 be wrapped in a :class:`io.BufferedReader` object for more speedups.
559 It also solves an issue where interleaved calls to `read()` and
560 `readline()` give wrong results. Patch by Nir Aides.
561
Jesse Noller1f0b6582010-01-27 03:36:01 +0000562- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
563 allowing for a maximum number of tasks within the pool to be completed by
564 the worker before that worker is terminated, and a new one created to
565 replace it.
566
Benjamin Petersond6326642010-01-27 02:25:58 +0000567- Issue #7792: Registering non-classes to ABCs raised an obscure error.
568
Benjamin Peterson9a11a362010-01-27 01:51:29 +0000569- Issue #7785: Don't accept bytes in FileIO.write().

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000723- Issue #6816: runpy now provides a run_path function that allows Python code
724 to execute file paths that refer to source or compiled Python files as well
725 as zipfiles, directories and other valid sys.path entries that contain a
726 __main__.py file. This allows applications that run other Python scripts to
727 support the same flexibility as the CPython command line itself.
728
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000729- Issue #7318: multiprocessing now uses a timeout when it fails to establish

747 recursive locks as fast as regular non-recursive locks (previously,
748 they were slower by 10x to 15x).

765 failures on systems with slightly bogus mtime behaviour.
766
Gregory P. Smith50467882009-11-01 18:42:17 +0000767- Issue #7246 & Issue #7208: getpass now properly flushes input before
768 reading from stdin so that existing input does not confuse it and
769 lead to incorrect entry or an IOError. It also properly flushes it
770 afterwards to avoid the terminal echoing the input afterwards on
771 OSes such as Solaris.

1110
Ezio Melotti184bdfb2010-02-18 09:37:05 +00001111- Issue #7712: test.support gained a new `temp_cwd` context manager which is

1133 user running the tests.
1134
R. David Murray35768ad2009-11-15 00:23:21 +00001135- Issue #7324: add a sanity check to regrtest argument parsing to

1140
Antoine Pitrou060cee22009-11-13 16:29:04 +00001141- Issue #6551: test_zipimport could import and then destroy some modules of
1142 the encodings package, which would make other tests fail further down
1143 the road because the internally cached encoders and decoders would point
1144 to empty global variables.
1145
Antoine Pitrou941ee882009-11-11 20:59:38 +00001146- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1158
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001159- Issue #7222: Make thread "reaping" more reliable so that reference
1160 leak-chasing test runs give sensible results. The previous method of
1161 reaping threads could return successfully while some Thread objects were
1162 still referenced. This also introduces a new private function:
1163 :func:`_thread._count()`.
1164
R. David Murray27144602009-10-19 15:26:16 +00001165- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1167
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001168- Issue #7055: test___all__ now greedily detects all modules which have an

1176
Brett Cannon3c273842009-07-20 00:14:29 +00001177- Fixed tests in importlib.test.source.test_abc_loader that were masking
1178 the proper exceptions that should be raised for missing or improper code
1179 object bytecode.
1180
Brett Cannonb49c70c2009-07-15 04:08:33 +00001181- Removed importlib's custom test discovery code and switched to

1371 than an int, which makes some operations possible under 64-bit Linux (e.g.

1451
Mark Dickinson865e01a2009-05-07 16:37:01 +00001452- Issue #5914: Add new C API function PyOS_string_to_double, and
1453 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1454
Eric Smith741191f2009-05-06 13:08:15 +00001455- Issue #3382: float.__format__, complex.__format__, and %-formatting
1456 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1457 affects nan -> NAN and inf -> INF.
1458
Mark Hammond5a607a32009-05-06 08:04:54 +00001459- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1460 in all operations, including splitdrive, split, etc. splitunc() now issues
1461 a PendingDeprecation warning.
1462
Eric Smith63376222009-05-05 14:04:18 +00001463- Issue #5920: For float.__format__, change the behavior with the
1464 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1465 to be like 'g' but with at least one decimal point and with a
1466 default precision of 12. Previously, the behavior the same but with
1467 a default precision of 6. This more closely matches str(), and
1468 reduces surprises when adding alignment flags to the empty
1469 presentation type. This also affects the new complex.__format__ in
1470 the same way.
1471
Martin v. Löwis011e8422009-05-05 04:43:17 +00001472- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1475 shadowed by classtype's, even if it was None. property now
1476 inserts the __doc__ into the subclass instance __dict__.

1480
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001481- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001483- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1484 received a new method, detach(). detach() disconnects the underlying stream
1485 from the buffer or text IO and returns it.
1486
Mark Dickinson33841c32009-05-01 15:37:04 +00001487- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1488 floats with absolute value over 1e50. Also remove length
1489 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1490 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001492- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001493 format(complex(1, 2./3), '.5') now produces a sensible result.
1494
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001495- Issue #5864: Fix empty format code formatting for floats so that it
1496 never gives more than the requested number of significant digits.
1497
Eric Smith6dc46f52009-04-27 20:39:49 +00001498- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1504 titlecase, but not their own uppercase.
1505
Benjamin Peterson193152c2009-04-25 01:08:45 +00001506- Issue #5283: Setting __class__ in __del__ caused a segfault.
1507
Mark Dickinsonad476da2009-04-23 19:14:16 +00001508- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1509 z involves nans, infs or negative zeros.
1510
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001511- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001512
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001513- Issue #1869 (and many duplicates): make round(x, n) correctly
1514 rounded for a float x, by using the decimal <-> binary conversions
1515 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1516 consistently agrees with format(x, '.2f').
1517
Benjamin Petersonae937c02009-04-18 20:54:08 +00001518- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1519 some builtin types.
1520
Eric Smith0923d1d2009-04-16 20:16:10 +00001521- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1522
Eric Smith35e84722009-04-16 20:21:28 +00001523- Issue #5515: str.format() type 'n' combined with commas and leading
1524 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001525
1526- Implement PEP 378, Format Specifier for Thousands Separator, for
1527 floats.
1528
Mark Dickinson3370cce2009-04-17 22:40:53 +00001529- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001530 1e11, not 1e12. This avoids printing 13 significant digits in
1531 situations where only 12 of them are correct. Example problem
1532 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1533 long time.)
1534
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001535- Issue #1580: On most platforms, use a 'short' float repr: for a
1536 finite float x, repr(x) now outputs a string based on the shortest
1537 sequence of decimal digits that rounds to x. Previous behaviour was
1538 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001539 Another minor difference is that the new repr switches to
1540 exponential notation at 1e16 instead of the previous 1e17; this
1541 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001542
1543 There's a new sys attribute sys.float_repr_style, which takes
1544 the value 'short' to indicate that we're using short float repr,
1545 and 'legacy' if the short float repr isn't available for one
1546 reason or another.
1547
1548 The float repr change involves incorporating David Gay's 'perfect
1549 rounding' code into the Python core (it's in Python/dtoa.c). As a
1550 secondary consequence, all string-to-float and float-to-string
1551 conversions (including all float formatting operations) will be
1552 correctly rounded on these platforms.
1553
1554 See issue 1580 discussions for details of platforms for which
1555 this change does not apply.
1556
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001557- Issue #5759: float() didn't call __float__ on str subclasses.
1558
Georg Brandlabc38772009-04-12 15:51:51 +00001559- The string.maketrans() function is deprecated; there is a new static method
1560 maketrans() on the bytes and bytearray classes. This removes confusion about
1561 the types string.maketrans() is supposed to work with, and mirrors the
1562 methods available on the str class.
1563
R. David Murraydc6da8a2009-04-09 22:16:43 +00001564- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1569
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001570- Issue #3739: The unicode-internal encoder now reports the number of characters

1729 untrackable objects are not tracked by the garbage collector. This can
1730 reduce the size of collections and therefore the garbage collection overhead
1731 on long-running programs, depending on their particular use of datatypes.

1796 (typically /dev/zero under Unix) could crash the interpreter.
1797
Benjamin Peterson59406a92009-03-26 17:10:29 +00001798- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

1800
Lars Gustäbel42e00912009-03-22 20:34:29 +00001801- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1802 forever on incomplete input. That caused tarfile.open() to hang when used
1803 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1804 partial bzip2 compressed data.
1805
Mark Dickinson79f52032009-03-17 23:12:51 +00001806- Issue #2110: Add support for thousands separator and 'n' type

1824 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001825 struct.error instead of returning b'\xff\xff\xff\xff'. The
1826 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1827 have been removed from the struct module.

1846 contained non ascii character on windows.
1847
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001848- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1849 source has already been decoded into str.
1850
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001851- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1852 rotating the object pointer by 4 bits to the right.
1853
Mark Dickinson87ec0852009-02-09 17:15:59 +00001854- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1855 it now forces its argument to double before testing for infinity.
1856
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001857- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1858 returns a non-number type.
1859
Benjamin Peterson87618552009-02-08 15:00:52 +00001860- Issue #5182: Removed memoryview.__str__.

1865 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001866
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001867- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001868 were suppressing all exceptions. These include list() and bytearray().
1869
Mark Dickinson1124e712009-01-28 21:25:58 +00001870- Issue #4707: round(x, n) now returns an integer if x is an integer.
1871 Previously it returned a float.
1872
Antoine Pitroub52ec782009-01-25 16:34:23 +00001873- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1874 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1875 evaluation loop is compiled with a new dispatch mechanism which gives
1876 speedups of up to 20%, depending on the system, on various benchmarks.
1877
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001878- Issue #4874: Most builtin decoders now reject unicode input.

1884
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001885- Issue #4838: When a module is deallocated, free the memory backing the
1886 optional module state data.
1887
Mark Dickinson8055afd2009-01-17 10:04:45 +00001888- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1889 type to (void *).
1890
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001891- Issue #4935: The overflow checking code in the expandtabs() method common
1892 to str, bytes and bytearray could be optimized away by the compiler, letting
1893 the interpreter segfault instead of raising an error.
1894
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001895- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1896 __next__ method.
1897
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001898- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1899 function no longer attempt to call the __long__ slot to convert an object
1900 to an integer. Only the __int__ and __trunc__ slots are examined.
1901
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001902- Issue #4893: Use NT threading on CE.
1903
Martin v. Löwisec59d042009-01-12 07:59:10 +00001904- Issue #4915: Port sysmodule to Windows CE.
1905
Antoine Pitrouab868312009-01-10 15:40:25 +00001906- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1907 common cases are optimized thanks to a dedicated fast path and a moderate
1908 amount of loop unrolling.
1909
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001910- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1911 collecting the oldest generation) so that allocating lots of objects without
1912 destroying them does not show quadratic performance. Based on a proposal by
1913 Martin von Löwis at
1914 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1915
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001916- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001917 having been closed (for instance, a read() call could return some
1918 previously buffered data). Patch by Dmitry Vasiliev.
1919
Antoine Pitrou05608432009-01-09 18:53:14 +00001920- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1921 flag to work properly. Furthermore, when specifying -u, the text stdout
1922 and stderr streams have line-by-line buffering enabled (the default being
1923 to buffer arbitrary chunks of data).
1924
Raymond Hettinger35631532009-01-09 03:58:09 +00001925- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1926 instead of ints (reducing its size from 4 to 8 times thereby reducing
1927 Python's overall memory).
1928
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001929- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1930 an existing .py counterpart, override the co_filename attributes of all
1931 code objects if the original filename is obsolete (which can happen if the
1932 file has been renamed, moved, or if it is accessed through different paths).
1933 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1934
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001935- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1936 one byte. Also fixes the meaning of len() so that it returns the number of
1937 items, rather than the size in bytes.
1938
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001939- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1940
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001941- Issue #4747: When the terminal does not use utf-8, executing a script with
1942 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1943
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001944- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001945 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001946
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001947- Issue #3680: Reference cycles created through a dict, set or deque iterator
1948 did not get collected.
1949
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001950- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1951 where the tp_hash and tp_dict slots are both NULL.
1952
Georg Brandlccc47b62008-12-28 11:44:14 +00001953- Issue #4759: None is now allowed as the first argument of
1954 bytearray.translate(). It was always allowed for bytes.translate().
1955
Skip Montanaro80072cb2008-12-23 03:51:14 +00001956- Added test case to ensure attempts to read from a file opened for writing
1957 fail.
1958
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001959- Issue #3106: Speedup some comparisons (str/str and int/int).

1963
Antoine Pitrou621601a2008-12-17 23:18:19 +00001964- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1965 print elapsed times, not only when some objects are uncollectable /
1966 unreachable. Original patch by Neil Schemenauer.
1967
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001968- Issue #3439: Add a bit_length method to int.
1969
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001970- Issue #2173: When getting device encoding, check that return value of
1971 nl_langinfo is not the empty string. This was causing silent build
1972 failures on OS X.
1973
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001974- Issue #4597: Fixed several opcodes that weren't always propagating
1975 exceptions.
1976
1977- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001978 context manager returns a value that cannot be converted to a bool.
1979
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001980- Issue #4445: Replace "sizeof(PyBytesObject)" with
1981 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1982 bytes instances. On a typical machine this saves 3 bytes of memory
1983 (on average) per allocation of a bytes instance.
1984
Christian Heimesa872de52008-12-05 08:26:55 +00001985- Issue #4533: File read operation was dreadfully slow due to a slowly
1986 growing read buffer. Fixed by using the same growth rate algorithm as
1987 Python 2.x.
1988
Antoine Pitrou5504e892008-12-06 21:27:53 +00001989- Issue #4509: Various issues surrounding resize of bytearray objects to
1990 which there are buffer exports (e.g. memoryview instances).
1991
Georg Brandlf9734072008-12-07 15:30:06 +00001992- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1993 method on file objects with closefd=False. The file descriptor is still
1994 kept open but the file object behaves like a closed file. The ``FileIO``
1995 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001996
Antoine Pitroubc420402008-12-07 20:14:49 +00001997- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2003
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002004- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2005 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2006 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2007 of using the replace error handler in PyUnicode_DecodeUTF8().
