21 changed.
22
Mark Dickinson3318d292010-04-06 16:53:17 +000023- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
24 on 64-bit machines. The shift count for either left or right shift is

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()
107 methods of bytes, bytearray and unicode objects by using a common
108 implementation based on stringlib's fast search. Patch by Florent Xicluna.

Mark Dickinson45b63652010-01-16 18:10:25 +0000110- Issue #7632: Fix various str -> float conversion bugs present in 2.7
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
163 several cases where reversed(range(a, b, c)) gave wrong results, and
164 fix a refleak for reversed(range(a, b, c)) with large arguments.

205 and include information from the Unihan.txt file.
206
Mark Dickinson2683ab02009-09-29 19:21:35 +0000207- Issue #7019: Raise ValueError when unmarshalling bad long data, instead
208 of producing internally inconsistent Python longs.

317
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000318- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
319 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
320
Victor Stinner0e59cc32010-04-16 23:49:32 +0000321- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
322 the current working directory.
323
Victor Stinner5bfe1462010-04-16 13:28:05 +0000324- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
325 using backslashreplace error handler
326
Victor Stinnercfa72782010-04-16 11:45:13 +0000327- Issue #8412: os.system() now accepts bytes, bytearray and str with
328 surrogates.
329
Senthil Kumaranad02d232010-04-16 03:02:13 +0000330- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
331 Locke and Hans Ulrich Niedermann.

R. David Murrayd48739f2010-04-14 18:59:18 +0000333- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
334
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000335- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
336 module now takes an optional timeout argument in seconds. Timeout support
337 relies on the system threading library, so as to avoid a semi-busy wait
338 loop.
339
Victor Stinner485fb562010-04-13 11:07:24 +0000340- Issue #8383: pickle and pickletools use surrogatepass error handler when
341 encoding unicode as utf8 to support lone surrogates and stay compatible with
342 Python 2.x and 3.0
343
R. David Murrayb2416e52010-04-12 16:58:02 +0000344- Issue #7585: difflib context and unified diffs now place a tab between
345 filename and date, conforming to the 'standards' they were originally
346 designed to follow. This improves compatibility with patch tools.
347
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000348- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
349 character sets will now consistently use a Content-Transfer-Encoding of
350 7bit rather than sometimes being marked as 8bit.
351
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000352- Issue #8375: test_distutils now checks if the temporary directory are still
353 present before it cleans them.
354
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000355- Issue #8374: Update the internal alias table in the :mod:`locale` module
356 to cover recent locale changes and additions.
357
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000358- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
359 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
360 and `ssl.OPENSSL_VERSION_NUMBER`.
361
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000362- Add functools.total_ordering() and functools.cmp_to_key().
363
Mark Dickinson089b00c2010-04-03 15:51:03 +0000364- Issue #8257: The Decimal construct now accepts a float instance
365 directly, converting that float to a Decimal of equal value:
366
367 >>> Decimal(1.1)
368 Decimal('1.100000000000000088817841970012523233890533447265625')
369
Mark Dickinson98127c32010-04-03 11:18:52 +0000370- Issue #8294: The Fraction constructor now accepts Decimal and float
371 instances directly.
372
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000373- Issue #7279: Comparisons involving a Decimal signaling NaN now
374 signal InvalidOperation instead of returning False. (Comparisons
375 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
376 are now hashable; Decimal signaling NaNs remain unhashable.
377
378- Issue #2531: Comparison operations between floats and Decimal
379 instances now return a result based on the numeric values of the
380 operands; previously they returned an arbitrary result based on
381 the relative ordering of id(float) and id(Decimal).
382
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000383- Added a subtract() method to collections.Counter().
384
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000385- Issue #8233: When run as a script, py_compile.py optionally takes a single
386 argument `-` which tells it to read files to compile from stdin. Each line
387 is read on demand and the named file is compiled immediately. (Original
388 patch by Piotr Ożarowski).
389
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000390- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
391 form feed (0x0C) are now considered linebreaks, as specified in Unicode
392 Standard Annex #14. See issue #7643.
393 http://www.unicode.org/reports/tr14/
394
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000395- Comparisons using one of <, <=, >, >= between a complex instance and
396 a Fractions instance now raise TypeError instead of returning
397 True/False. This makes Fraction <=> complex comparisons consistent with
398 int <=> complex, float <=> complex, and complex <=> complex comparisons.
399
Antoine Pitrou39b35432010-03-23 00:25:54 +0000400- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
401 some methods (such as oss_mixer_device.fileno()) were not available.
402 Initial patch by Bertrand Janin.
403
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000404- Issue #8205: Remove the "Modules" directory from sys.path when Python is
405 running from the build directory (POSIX only).
406
Antoine Pitrou910bd512010-03-22 20:11:09 +0000407- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
408 didn't support chflags() (for example ZFS under FreeBSD). The error is
409 now silenced.
410
R. David Murrayca2edce2010-03-22 17:48:48 +0000411- Issue #7860: platform.uname now reports the correct 'machine' type
412 when Python is running in WOW64 mode on 64 bit Windows.
413
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000414- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
415 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
416 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000417
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000418- Issue #4282: Fix the main function of the profile module for a non-ASCII
419 script, open the file in binary mode and not in text mode with the default
420 (utf8) encoding.
421
Florent Xicluna54467e02010-03-21 12:29:50 +0000422- Issue #8179: Fix macpath.realpath() on a non-existing path.
423
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000424- Issue #8024: Update the Unicode database to 5.2.
425
Benjamin Peterson00888932010-03-18 22:37:38 +0000426- Issue #8168: py_compile now handles files with utf-8 BOMS.
427
Benjamin Peterson689a5582010-03-18 22:29:52 +0000428- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
429 detected.
430
Martin v. Löwis4b003072010-03-16 13:19:21 +0000431- Issue #6716/2: Backslash-replace error output in compilall.
432
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000433- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
434 with Tcl/Tk-8.5.
435
Matthias Klosec33b9022010-03-16 00:36:26 +0000436- Issue #8140: extend compileall to compile single files. Add -i option.

Matthias Klose82f60912010-03-15 13:46:04 +0000438- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
439 the locale.
440
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000441- The internals of the subprocess module on POSIX systems have been replaced
442 by an extension module (_posixsubprocess) so that the fork()+exec() can be
443 done safely without the possibility of deadlock in multithreaded applications.
444
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000445- subprocess.Popen now has restore_signals and start_new_session features.
446 The default of restore_signals=True is a new behavior compared to earlier
447 Python versions. This means that signals such as SIGPIPE are not ignored
448 by default in subprocesses launched by Python (Issue #1652).
449
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000450- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

460 the replacement were all bytes. Patch by Antoine Pitrou.
461
Gerhard Häringf9cee222010-03-05 15:20:03 +0000462- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
463 bugs and allows loading SQLite extensions from shared libraries.

Florent Xiclunac279ebf2010-02-27 11:31:21 +0000479- Issue #691291: codecs.open() should not convert end of lines on reading and
480 writing.
481
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000482- Issue #7869: logging: improved diagnostic for format-time errors.

496 to be ignored only to the first file. Noted by Bogdan Opanchuk.
497
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000498- Issue #7597: curses.use_env() can now be called before initscr().
499 Noted by Kan-Ru Chen.

507 bytecode file when it was less then 8 bytes.
508
Mark Dickinson84230a12010-02-18 14:49:50 +0000509- Issue #7633: In the decimal module, Context class methods (with the
510 exception of canonical and is_canonical) now accept instances of int
511 and long wherever a Decimal instance is accepted, and implicitly
512 convert that argument to Decimal. Previously only some arguments
513 were converted.
514
R. David Murray1f449142010-02-11 00:15:05 +0000515- Issue #7835: shelve should no longer produce mysterious warnings during
516 interpreter shutdown.
517
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000518- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
519 in XML processing instructions and comments. These raw characters are
520 allowed by the XML specification, and are necessary when outputting e.g.
521 PHP code in a processing instruction. Patch by Neil Muller.

533 type is specified. Patch by Brian Curtin.
534
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000535- Issue #6939: Fix file I/O objects in the `io` module to keep the original
536 file position when calling `truncate()`. It would previously change the
537 file position to the given argument, which goes against the tradition of
538 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
539
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000540- Issue #7610: Reworked implementation of the internal
541 :class:`zipfile.ZipExtFile` class used to represent files stored inside
542 an archive. The new implementation is significantly faster and can
543 be wrapped in a :class:`io.BufferedReader` object for more speedups.
544 It also solves an issue where interleaved calls to `read()` and
545 `readline()` give wrong results. Patch by Nir Aides.
546
Jesse Noller1f0b6582010-01-27 03:36:01 +0000547- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

549 the worker before that worker is terminated, and a new one created to
550 replace it.
551
Benjamin Petersond6326642010-01-27 02:25:58 +0000552- Issue #7792: Registering non-classes to ABCs raised an obscure error.

707
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000708- Issue #6816: runpy now provides a run_path function that allows Python code
709 to execute file paths that refer to source or compiled Python files as well
710 as zipfiles, directories and other valid sys.path entries that contain a
711 __main__.py file. This allows applications that run other Python scripts to
712 support the same flexibility as the CPython command line itself.
713
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000714- Issue #7318: multiprocessing now uses a timeout when it fails to establish
715 a connection with another process, rather than looping endlessly. The
716 default timeout is 20 seconds, which should be amply sufficient for
717 local connections.

731 default when instantiating a `threading.RLock` object. This makes
732 recursive locks as fast as regular non-recursive locks (previously,
733 they were slower by 10x to 15x).
734
Antoine Pitroub0872682009-11-09 16:08:16 +0000735- Issue #7282: Fix a memory leak when an RLock was used in a thread other

749 a modification is done through it. This fixes inconsistencies and test
750 failures on systems with slightly bogus mtime behaviour.
751
Gregory P. Smith50467882009-11-01 18:42:17 +0000752- Issue #7246 & Issue #7208: getpass now properly flushes input before
753 reading from stdin so that existing input does not confuse it and
754 lead to incorrect entry or an IOError. It also properly flushes it
755 afterwards to avoid the terminal echoing the input afterwards on
756 OSes such as Solaris.

1118 user running the tests.
1119
R. David Murray35768ad2009-11-15 00:23:21 +00001120- Issue #7324: add a sanity check to regrtest argument parsing to

1125
Antoine Pitrou060cee22009-11-13 16:29:04 +00001126- Issue #6551: test_zipimport could import and then destroy some modules of

1143
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001144- Issue #7222: Make thread "reaping" more reliable so that reference
1145 leak-chasing test runs give sensible results. The previous method of
1146 reaping threads could return successfully while some Thread objects were
1147 still referenced. This also introduces a new private function:
1148 :func:`_thread._count()`.
1149
R. David Murray27144602009-10-19 15:26:16 +00001150- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1151 longer runs the risk of causing the worker thread to fail.
1152
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001153- Issue #7055: test___all__ now greedily detects all modules which have an

1161
Brett Cannon3c273842009-07-20 00:14:29 +00001162- Fixed tests in importlib.test.source.test_abc_loader that were masking
1163 the proper exceptions that should be raised for missing or improper code

1451 default precision of 12. Previously, the behavior the same but with
1452 a default precision of 6. This more closely matches str(), and

Mark Dickinsonc6300392009-04-20 21:38:00 +00001497
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001498- Issue #1869 (and many duplicates): make round(x, n) correctly
1499 rounded for a float x, by using the decimal <-> binary conversions
1500 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1501 consistently agrees with format(x, '.2f').
1502
Benjamin Petersonae937c02009-04-18 20:54:08 +00001503- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1504 some builtin types.
1505
Eric Smith0923d1d2009-04-16 20:16:10 +00001506- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1507
Eric Smith35e84722009-04-16 20:21:28 +00001508- Issue #5515: str.format() type 'n' combined with commas and leading
1509 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001510
1511- Implement PEP 378, Format Specifier for Thousands Separator, for
1512 floats.
1513
Mark Dickinson3370cce2009-04-17 22:40:53 +00001514- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001515 1e11, not 1e12. This avoids printing 13 significant digits in
1516 situations where only 12 of them are correct. Example problem
1517 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1518 long time.)
1519
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001520- Issue #1580: On most platforms, use a 'short' float repr: for a
1521 finite float x, repr(x) now outputs a string based on the shortest
1522 sequence of decimal digits that rounds to x. Previous behaviour was
1523 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001524 Another minor difference is that the new repr switches to
1525 exponential notation at 1e16 instead of the previous 1e17; this
1526 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001527
1528 There's a new sys attribute sys.float_repr_style, which takes
1529 the value 'short' to indicate that we're using short float repr,
1530 and 'legacy' if the short float repr isn't available for one
1531 reason or another.
1532
1533 The float repr change involves incorporating David Gay's 'perfect
1534 rounding' code into the Python core (it's in Python/dtoa.c). As a
1535 secondary consequence, all string-to-float and float-to-string
1536 conversions (including all float formatting operations) will be
1537 correctly rounded on these platforms.
1538
1539 See issue 1580 discussions for details of platforms for which
1540 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001542- Issue #5759: float() didn't call __float__ on str subclasses.
1543
Georg Brandlabc38772009-04-12 15:51:51 +00001544- The string.maketrans() function is deprecated; there is a new static method
1545 maketrans() on the bytes and bytearray classes. This removes confusion about
1546 the types string.maketrans() is supposed to work with, and mirrors the
1547 methods available on the str class.
1548
R. David Murraydc6da8a2009-04-09 22:16:43 +00001549- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Walter Dörwald8dc33d52009-05-06 14:41:26 +00001555- Issue #3739: The unicode-internal encoder now reports the number of characters

1712
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001713- Issue #4688: Add a heuristic so that tuples and dicts containing only
1714 untrackable objects are not tracked by the garbage collector. This can
1715 reduce the size of collections and therefore the garbage collection overhead
1716 on long-running programs, depending on their particular use of datatypes.

1724 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1725 --enable-big-digits option to configure, which overrides the
1726 default. Add sys.int_info structseq to provide information about
1727 the internal format.

1730 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1731 and sizeof(Py_UNICODE) == 2.
1732
Eric Smith8ec90442009-03-14 12:29:34 +00001733- Issue #5237: Allow auto-numbered fields in str.format(). For

1782
Benjamin Peterson59406a92009-03-26 17:10:29 +00001783- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1784 io.BufferedRandom have been deprecated for removal in Python 3.2.
1785
Lars Gustäbel42e00912009-03-22 20:34:29 +00001786- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1787 forever on incomplete input. That caused tarfile.open() to hang when used
1788 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1789 partial bzip2 compressed data.
1790
Mark Dickinson79f52032009-03-17 23:12:51 +00001791- Issue #2110: Add support for thousands separator and 'n' type

1795 '>' alignment characters.
1796
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00001797- The error detection code in FileIO.close() could fail to reflect the `errno`

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001810 struct.error instead of returning b'\xff\xff\xff\xff'. The
1811 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1812 have been removed from the struct module.

1831 contained non ascii character on windows.
1832
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001833- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the

1837 rotating the object pointer by 4 bits to the right.
1838
Mark Dickinson87ec0852009-02-09 17:15:59 +00001839- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1840 it now forces its argument to double before testing for infinity.
1841
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001842- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1843 returns a non-number type.
1844
Benjamin Peterson87618552009-02-08 15:00:52 +00001845- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001851
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001852- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001853 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00001855- Issue #4707: round(x, n) now returns an integer if x is an integer.
1856 Previously it returned a float.
1857
Antoine Pitroub52ec782009-01-25 16:34:23 +00001858- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1859 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1860 evaluation loop is compiled with a new dispatch mechanism which gives
1861 speedups of up to 20%, depending on the system, on various benchmarks.
1862
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001863- Issue #4874: Most builtin decoders now reject unicode input.

1869
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001870- Issue #4838: When a module is deallocated, free the memory backing the
1871 optional module state data.
1872
Mark Dickinson8055afd2009-01-17 10:04:45 +00001873- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1874 type to (void *).
1875
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001876- Issue #4935: The overflow checking code in the expandtabs() method common
1877 to str, bytes and bytearray could be optimized away by the compiler, letting
1878 the interpreter segfault instead of raising an error.
1879
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001880- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1881 __next__ method.
1882
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001883- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1884 function no longer attempt to call the __long__ slot to convert an object
1885 to an integer. Only the __int__ and __trunc__ slots are examined.
1886
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001887- Issue #4893: Use NT threading on CE.
1888

1890
Antoine Pitrouab868312009-01-10 15:40:25 +00001891- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1892 common cases are optimized thanks to a dedicated fast path and a moderate
1893 amount of loop unrolling.
1894
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001895- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1896 collecting the oldest generation) so that allocating lots of objects without
1897 destroying them does not show quadratic performance. Based on a proposal by
1898 Martin von Löwis at
1899 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1900
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001901- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001902 having been closed (for instance, a read() call could return some
1903 previously buffered data). Patch by Dmitry Vasiliev.
1904
Antoine Pitrou05608432009-01-09 18:53:14 +00001905- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1906 flag to work properly. Furthermore, when specifying -u, the text stdout
1907 and stderr streams have line-by-line buffering enabled (the default being
1908 to buffer arbitrary chunks of data).
1909
Raymond Hettinger35631532009-01-09 03:58:09 +00001910- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1911 instead of ints (reducing its size from 4 to 8 times thereby reducing
1912 Python's overall memory).
1913
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001914- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1915 an existing .py counterpart, override the co_filename attributes of all
1916 code objects if the original filename is obsolete (which can happen if the
1917 file has been renamed, moved, or if it is accessed through different paths).
1918 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1919
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001920- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1921 one byte. Also fixes the meaning of len() so that it returns the number of
1922 items, rather than the size in bytes.
1923
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001924- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1925
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001926- Issue #4747: When the terminal does not use utf-8, executing a script with
1927 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1928
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001929- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001930 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001931
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001932- Issue #3680: Reference cycles created through a dict, set or deque iterator
1933 did not get collected.
1934
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001935- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1936 where the tp_hash and tp_dict slots are both NULL.
1937
Georg Brandlccc47b62008-12-28 11:44:14 +00001938- Issue #4759: None is now allowed as the first argument of
1939 bytearray.translate(). It was always allowed for bytes.translate().
1940
Skip Montanaro80072cb2008-12-23 03:51:14 +00001941- Added test case to ensure attempts to read from a file opened for writing
1942 fail.
1943
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001944- Issue #3106: Speedup some comparisons (str/str and int/int).

1948
Antoine Pitrou621601a2008-12-17 23:18:19 +00001949- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1950 print elapsed times, not only when some objects are uncollectable /
1951 unreachable. Original patch by Neil Schemenauer.
1952

1954
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001955- Issue #2173: When getting device encoding, check that return value of
1956 nl_langinfo is not the empty string. This was causing silent build
1957 failures on OS X.
1958
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001959- Issue #4597: Fixed several opcodes that weren't always propagating
1960 exceptions.
1961
1962- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001963 context manager returns a value that cannot be converted to a bool.
1964
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001965- Issue #4445: Replace "sizeof(PyBytesObject)" with
1966 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1967 bytes instances. On a typical machine this saves 3 bytes of memory
1968 (on average) per allocation of a bytes instance.
1969
Christian Heimesa872de52008-12-05 08:26:55 +00001970- Issue #4533: File read operation was dreadfully slow due to a slowly
1971 growing read buffer. Fixed by using the same growth rate algorithm as
1972 Python 2.x.
1973
Antoine Pitrou5504e892008-12-06 21:27:53 +00001974- Issue #4509: Various issues surrounding resize of bytearray objects to
1975 which there are buffer exports (e.g. memoryview instances).
1976
Georg Brandlf9734072008-12-07 15:30:06 +00001977- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1978 method on file objects with closefd=False. The file descriptor is still
1979 kept open but the file object behaves like a closed file. The ``FileIO``
1980 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001981
Antoine Pitroubc420402008-12-07 20:14:49 +00001982- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1988
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001989- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1990 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1991 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1992 of using the replace error handler in PyUnicode_DecodeUTF8().
