16 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
17 benefit compared to the dynamic memory allocation fallback. Patch by
18 Charles-François Natali.
19
Benjamin Peterson8380dd52010-04-16 22:51:37 +000020- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
21 passed to bytes or bytearray.

26 changed.
27
Mark Dickinson3318d292010-04-06 16:53:17 +000028- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
29 on 64-bit machines. The shift count for either left or right shift is
30 permitted to be up to sys.maxsize.
31
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000032- Ensure that tokenization of identifiers is not affected by locale.

Mark Dickinsonf673f0c2010-03-13 09:48:39 +000049- Issue #7845: Rich comparison methods on the complex type now return
50 NotImplemented rather than raising a TypeError when comparing with an
51 incompatible type; this allows user-defined classes to implement their own
52 comparisons with complex.
53
Victor Stinner52f6dd72010-03-12 14:45:56 +000054- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt

89
Mark Dickinsonbc099642010-01-29 17:27:24 +000090- Issue #7788: Fix an interpreter crash produced by deleting a list
91 slice with very large step value.
92
Eric Smithf7bb5782010-01-27 00:44:57 +000093- Issue #7766: Change sys.getwindowsversion() return value to a named
94 tuple and add the additional members returned in an OSVERSIONINFOEX
95 structure. The new members are service_pack_major, service_pack_minor,
96 suite_mask, and product_type.
97
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000098- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
99 could crash in many places because of the PyByteArray_AS_STRING() macro
100 returning NULL. The macro now returns a statically allocated empty
101 string instead.
102
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000103- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
104 where the right hand operand is a set of constants, by turning the set into
105 a frozenset and pre-building it as a constant. The comparison operation
106 is made against the constant instead of building a new set each time it is
107 executed (a similar optimization already existed which turned a list of
108 constants into a pre-built tuple). Patch and additional tests by Dave
109 Malcolm.
110
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000111- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

116 alpha 2, including: (1) a serious 'wrong output' bug that could
117 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
118 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000119 strings corresponding to subnormal values, (3) a memory leak for
120 some values large enough to cause overflow, and (4) a number of
121 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000122
Benjamin Petersonaea44282010-01-04 01:10:28 +0000123- The __complex__ method is now looked up on the class of instances to make it

127 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
128
Benjamin Petersond12362a2009-12-30 19:44:54 +0000129- Issue #7604: Deleting an unset slotted attribute did not raise an
130 AttributeError.
131

133 negative zero) in ** operator. The behaviour now conforms to that
134 described in C99 Annex F.
135
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000136- Issue #1811: improve accuracy and cross-platform consistency for
137 true division of integers: the result of a/b is now correctly
138 rounded for ints a and b (at least on IEEE 754 platforms), and in
139 particular does not depend on the internal representation of an int.
140
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000141- Issue #6834: replace the implementation for the 'python' and 'pythonw'
142 executables on OSX.
143
144 These executables now work properly with the arch(1) command:
145 ``arch -ppc python`` will start a universal binary version of python
146 in PPC mode (unlike previous releases).
147
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000148- Issue #7466: segmentation fault when the garbage collector is called

163 implement the relevant rich comparison methods.
164
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000165- Issue #7298: fixes for range and reversed(range(...)). Iteration
166 over range(a, b, c) incorrectly gave an empty iterator when a, b and
167 c fit in C long but the length of the range did not. Also fix
168 several cases where reversed(range(a, b, c)) gave wrong results, and
169 fix a refleak for reversed(range(a, b, c)) with large arguments.

315- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
316 ``const char *`` as the string is stored beyond the call.
317
Benjamin Peterson05159c42009-12-03 03:01:27 +0000318- Issue #2422: When compiled with the ``--with-valgrind`` option, the
319 pymalloc allocator will be automatically disabled when running under
320 Valgrind. This gives improved memory leak detection when running
321 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitroufec12ff2010-04-21 19:46:23 +0000326- Issue #8484: Load all ciphers and digest algorithms when initializing
327 the _ssl extension, such that verification of some SSL certificates
328 doesn't fail because of an "unknown algorithm".
329
Tarek Ziadéfb437512010-04-20 08:57:33 +0000330- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.

Tarek Ziadé5340db32010-04-19 22:30:51 +0000332- Issue #1540112: Now allowing the choice of a copy function in
333 shutil.copytree.
334
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000335- Issue #4814: timeout parameter is now applied also for connections resulting
336 from PORT/EPRT commands.
337
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000338- Issue #8463: added missing reference to bztar in shutil's documentation.
339
Ronald Oussoren84151202010-04-18 20:46:11 +0000340- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
341 (as long as the user didn't specify 'automatic proxy configuration').
342
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000343- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
344 code as stated in RFC-959 at chapter 5.4.
345
Victor Stinner738446f02010-04-18 00:00:44 +0000346- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
347 surrogates.
348
Antoine Pitrou0454af92010-04-17 23:51:58 +0000349- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000350 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

368
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000369- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
370 module now takes an optional timeout argument in seconds. Timeout support
371 relies on the system threading library, so as to avoid a semi-busy wait
372 loop.
373
Victor Stinner485fb562010-04-13 11:07:24 +0000374- Issue #8383: pickle and pickletools use surrogatepass error handler when

376 Python 2.x and 3.0
377
R. David Murrayb2416e52010-04-12 16:58:02 +0000378- Issue #7585: difflib context and unified diffs now place a tab between
379 filename and date, conforming to the 'standards' they were originally
380 designed to follow. This improves compatibility with patch tools.
381
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000382- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
383 character sets will now consistently use a Content-Transfer-Encoding of
384 7bit rather than sometimes being marked as 8bit.
385
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000386- Issue #8375: test_distutils now checks if the temporary directory are still
387 present before it cleans them.

393 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
394 and `ssl.OPENSSL_VERSION_NUMBER`.
395
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000396- Add functools.total_ordering() and functools.cmp_to_key().
397
Mark Dickinson089b00c2010-04-03 15:51:03 +0000398- Issue #8257: The Decimal construct now accepts a float instance
399 directly, converting that float to a Decimal of equal value:
400
401 >>> Decimal(1.1)
402 Decimal('1.100000000000000088817841970012523233890533447265625')
403
Mark Dickinson98127c32010-04-03 11:18:52 +0000404- Issue #8294: The Fraction constructor now accepts Decimal and float
405 instances directly.
406
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000407- Issue #7279: Comparisons involving a Decimal signaling NaN now
408 signal InvalidOperation instead of returning False. (Comparisons
409 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
410 are now hashable; Decimal signaling NaNs remain unhashable.
411
412- Issue #2531: Comparison operations between floats and Decimal
413 instances now return a result based on the numeric values of the
414 operands; previously they returned an arbitrary result based on
415 the relative ordering of id(float) and id(Decimal).
416
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000417- Added a subtract() method to collections.Counter().
418
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000419- Issue #8233: When run as a script, py_compile.py optionally takes a single
420 argument `-` which tells it to read files to compile from stdin. Each line
421 is read on demand and the named file is compiled immediately. (Original
422 patch by Piotr Ożarowski).
423
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000424- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
425 form feed (0x0C) are now considered linebreaks, as specified in Unicode
426 Standard Annex #14. See issue #7643.
427 http://www.unicode.org/reports/tr14/
428
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000429- Comparisons using one of <, <=, >, >= between a complex instance and
430 a Fractions instance now raise TypeError instead of returning
431 True/False. This makes Fraction <=> complex comparisons consistent with
432 int <=> complex, float <=> complex, and complex <=> complex comparisons.
433
Antoine Pitrou39b35432010-03-23 00:25:54 +0000434- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
435 some methods (such as oss_mixer_device.fileno()) were not available.
436 Initial patch by Bertrand Janin.
437
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000438- Issue #8205: Remove the "Modules" directory from sys.path when Python is
439 running from the build directory (POSIX only).
440
Antoine Pitrou910bd512010-03-22 20:11:09 +0000441- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
442 didn't support chflags() (for example ZFS under FreeBSD). The error is
443 now silenced.
444
R. David Murrayca2edce2010-03-22 17:48:48 +0000445- Issue #7860: platform.uname now reports the correct 'machine' type
446 when Python is running in WOW64 mode on 64 bit Windows.
447
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000448- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
449 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
450 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000451
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000452- Issue #4282: Fix the main function of the profile module for a non-ASCII

461
Benjamin Peterson689a5582010-03-18 22:29:52 +0000462- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
463 detected.
464
Martin v. Löwis4b003072010-03-16 13:19:21 +0000465- Issue #6716/2: Backslash-replace error output in compilall.

Matthias Klosea6d9abf2010-03-16 10:51:28 +0000467- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
468 with Tcl/Tk-8.5.
469
Matthias Klosec33b9022010-03-16 00:36:26 +0000470- Issue #8140: extend compileall to compile single files. Add -i option.

473 the locale.
474
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000475- The internals of the subprocess module on POSIX systems have been replaced
476 by an extension module (_posixsubprocess) so that the fork()+exec() can be
477 done safely without the possibility of deadlock in multithreaded applications.
478
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000479- subprocess.Popen now has restore_signals and start_new_session features.
480 The default of restore_signals=True is a new behavior compared to earlier
481 Python versions. This means that signals such as SIGPIPE are not ignored
482 by default in subprocesses launched by Python (Issue #1652).
483
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000484- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
485 cElementTree module is updated too.

494 the replacement were all bytes. Patch by Antoine Pitrou.
495
Gerhard Häringf9cee222010-03-05 15:20:03 +0000496- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
497 bugs and allows loading SQLite extensions from shared libraries.

530 to be ignored only to the first file. Noted by Bogdan Opanchuk.
531
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000532- Issue #7597: curses.use_env() can now be called before initscr().
533 Noted by Kan-Ru Chen.

541 bytecode file when it was less then 8 bytes.
542
Mark Dickinson84230a12010-02-18 14:49:50 +0000543- Issue #7633: In the decimal module, Context class methods (with the
544 exception of canonical and is_canonical) now accept instances of int
545 and long wherever a Decimal instance is accepted, and implicitly
546 convert that argument to Decimal. Previously only some arguments
547 were converted.
548
R. David Murray1f449142010-02-11 00:15:05 +0000549- Issue #7835: shelve should no longer produce mysterious warnings during
550 interpreter shutdown.
551
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000552- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
553 in XML processing instructions and comments. These raw characters are
554 allowed by the XML specification, and are necessary when outputting e.g.
555 PHP code in a processing instruction. Patch by Neil Muller.

567 type is specified. Patch by Brian Curtin.
568
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000569- Issue #6939: Fix file I/O objects in the `io` module to keep the original
570 file position when calling `truncate()`. It would previously change the
571 file position to the given argument, which goes against the tradition of
572 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
573
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000574- Issue #7610: Reworked implementation of the internal
575 :class:`zipfile.ZipExtFile` class used to represent files stored inside
576 an archive. The new implementation is significantly faster and can
577 be wrapped in a :class:`io.BufferedReader` object for more speedups.
578 It also solves an issue where interleaved calls to `read()` and
579 `readline()` give wrong results. Patch by Nir Aides.
580
Jesse Noller1f0b6582010-01-27 03:36:01 +0000581- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
582 allowing for a maximum number of tasks within the pool to be completed by
583 the worker before that worker is terminated, and a new one created to
584 replace it.
585
Benjamin Petersond6326642010-01-27 02:25:58 +0000586- Issue #7792: Registering non-classes to ABCs raised an obscure error.

743 to execute file paths that refer to source or compiled Python files as well

926

1191 leak-chasing test runs give sensible results. The previous method of
1192 reaping threads could return successfully while some Thread objects were
1193 still referenced. This also introduces a new private function:

1499 reduces surprises when adding alignment flags to the empty
1500 presentation type. This also affects the new complex.__format__ in
1501 the same way.

Martin v. Löwis011e8422009-05-05 04:43:17 +00001503- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1504
R. David Murrayb18500d2009-05-04 22:59:07 +00001505- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1506 shadowed by classtype's, even if it was None. property now
1507 inserts the __doc__ into the subclass instance __dict__.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001514- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1515 received a new method, detach(). detach() disconnects the underlying stream
1516 from the buffer or text IO and returns it.
1517
Mark Dickinson33841c32009-05-01 15:37:04 +00001518- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1519 floats with absolute value over 1e50. Also remove length
1520 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1521 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001522
Eric Smith741191f2009-05-06 13:08:15 +00001523- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001524 format(complex(1, 2./3), '.5') now produces a sensible result.
1525
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001526- Issue #5864: Fix empty format code formatting for floats so that it
1527 never gives more than the requested number of significant digits.
1528
Eric Smith6dc46f52009-04-27 20:39:49 +00001529- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1536
Benjamin Peterson193152c2009-04-25 01:08:45 +00001537- Issue #5283: Setting __class__ in __del__ caused a segfault.
1538
Mark Dickinsonad476da2009-04-23 19:14:16 +00001539- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1540 z involves nans, infs or negative zeros.
1541
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001542- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001543
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001544- Issue #1869 (and many duplicates): make round(x, n) correctly
1545 rounded for a float x, by using the decimal <-> binary conversions
1546 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1547 consistently agrees with format(x, '.2f').
1548
Benjamin Petersonae937c02009-04-18 20:54:08 +00001549- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1550 some builtin types.
1551
Eric Smith0923d1d2009-04-16 20:16:10 +00001552- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1553
Eric Smith35e84722009-04-16 20:21:28 +00001554- Issue #5515: str.format() type 'n' combined with commas and leading
1555 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001556
1557- Implement PEP 378, Format Specifier for Thousands Separator, for
1558 floats.
1559
Mark Dickinson3370cce2009-04-17 22:40:53 +00001560- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001561 1e11, not 1e12. This avoids printing 13 significant digits in
1562 situations where only 12 of them are correct. Example problem
1563 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1564 long time.)
1565
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001566- Issue #1580: On most platforms, use a 'short' float repr: for a
1567 finite float x, repr(x) now outputs a string based on the shortest
1568 sequence of decimal digits that rounds to x. Previous behaviour was
1569 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001570 Another minor difference is that the new repr switches to
1571 exponential notation at 1e16 instead of the previous 1e17; this
1572 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001573
1574 There's a new sys attribute sys.float_repr_style, which takes
1575 the value 'short' to indicate that we're using short float repr,
1576 and 'legacy' if the short float repr isn't available for one
1577 reason or another.
1578
1579 The float repr change involves incorporating David Gay's 'perfect
1580 rounding' code into the Python core (it's in Python/dtoa.c). As a
1581 secondary consequence, all string-to-float and float-to-string
1582 conversions (including all float formatting operations) will be
1583 correctly rounded on these platforms.
1584
1585 See issue 1580 discussions for details of platforms for which
1586 this change does not apply.
1587
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001588- Issue #5759: float() didn't call __float__ on str subclasses.
1589
Georg Brandlabc38772009-04-12 15:51:51 +00001590- The string.maketrans() function is deprecated; there is a new static method
1591 maketrans() on the bytes and bytearray classes. This removes confusion about
1592 the types string.maketrans() is supposed to work with, and mirrors the
1593 methods available on the str class.
1594
R. David Murraydc6da8a2009-04-09 22:16:43 +00001595- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1758
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001759- Issue #4688: Add a heuristic so that tuples and dicts containing only
1760 untrackable objects are not tracked by the garbage collector. This can
1761 reduce the size of collections and therefore the garbage collection overhead
1762 on long-running programs, depending on their particular use of datatypes.

1883 rotating the object pointer by 4 bits to the right.
1884
Mark Dickinson87ec0852009-02-09 17:15:59 +00001885- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1886 it now forces its argument to double before testing for infinity.
1887
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001888- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001897
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001898- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001899 were suppressing all exceptions. These include list() and bytearray().
1900
Mark Dickinson1124e712009-01-28 21:25:58 +00001901- Issue #4707: round(x, n) now returns an integer if x is an integer.
1902 Previously it returned a float.
1903
Antoine Pitroub52ec782009-01-25 16:34:23 +00001904- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1905 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1906 evaluation loop is compiled with a new dispatch mechanism which gives
1907 speedups of up to 20%, depending on the system, on various benchmarks.
1908
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001909- Issue #4874: Most builtin decoders now reject unicode input.

1915
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001916- Issue #4838: When a module is deallocated, free the memory backing the
1917 optional module state data.
1918
Mark Dickinson8055afd2009-01-17 10:04:45 +00001919- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1920 type to (void *).
1921
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001922- Issue #4935: The overflow checking code in the expandtabs() method common
1923 to str, bytes and bytearray could be optimized away by the compiler, letting
1924 the interpreter segfault instead of raising an error.
1925
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001926- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1927 __next__ method.
1928
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001929- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1930 function no longer attempt to call the __long__ slot to convert an object
1931 to an integer. Only the __int__ and __trunc__ slots are examined.
1932
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001933- Issue #4893: Use NT threading on CE.
1934

1936
Antoine Pitrouab868312009-01-10 15:40:25 +00001937- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1938 common cases are optimized thanks to a dedicated fast path and a moderate
1939 amount of loop unrolling.
1940
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001941- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1942 collecting the oldest generation) so that allocating lots of objects without
1943 destroying them does not show quadratic performance. Based on a proposal by
1944 Martin von Löwis at
1945 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1946
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001947- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001948 having been closed (for instance, a read() call could return some
1949 previously buffered data). Patch by Dmitry Vasiliev.
1950
Antoine Pitrou05608432009-01-09 18:53:14 +00001951- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1952 flag to work properly. Furthermore, when specifying -u, the text stdout
1953 and stderr streams have line-by-line buffering enabled (the default being
1954 to buffer arbitrary chunks of data).
1955
Raymond Hettinger35631532009-01-09 03:58:09 +00001956- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1957 instead of ints (reducing its size from 4 to 8 times thereby reducing
1958 Python's overall memory).
1959
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001960- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1961 an existing .py counterpart, override the co_filename attributes of all
1962 code objects if the original filename is obsolete (which can happen if the
1963 file has been renamed, moved, or if it is accessed through different paths).
1964 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1965
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001966- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1967 one byte. Also fixes the meaning of len() so that it returns the number of
1968 items, rather than the size in bytes.
1969
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001970- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1971
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001972- Issue #4747: When the terminal does not use utf-8, executing a script with
1973 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1974
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001975- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001976 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001977
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001978- Issue #3680: Reference cycles created through a dict, set or deque iterator
1979 did not get collected.
1980
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001981- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1982 where the tp_hash and tp_dict slots are both NULL.
1983
Georg Brandlccc47b62008-12-28 11:44:14 +00001984- Issue #4759: None is now allowed as the first argument of
1985 bytearray.translate(). It was always allowed for bytes.translate().
1986
Skip Montanaro80072cb2008-12-23 03:51:14 +00001987- Added test case to ensure attempts to read from a file opened for writing
1988 fail.
1989
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001990- Issue #3106: Speedup some comparisons (str/str and int/int).

1993 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1994
Antoine Pitrou621601a2008-12-17 23:18:19 +00001995- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1996 print elapsed times, not only when some objects are uncollectable /
1997 unreachable. Original patch by Neil Schemenauer.
1998
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001999- Issue #3439: Add a bit_length method to int.
2000
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002001- Issue #2173: When getting device encoding, check that return value of
2002 nl_langinfo is not the empty string. This was causing silent build
2003 failures on OS X.
2004
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002005- Issue #4597: Fixed several opcodes that weren't always propagating
2006 exceptions.
2007
2008- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002009 context manager returns a value that cannot be converted to a bool.
2010
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002011- Issue #4445: Replace "sizeof(PyBytesObject)" with
2012 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2013 bytes instances. On a typical machine this saves 3 bytes of memory
2014 (on average) per allocation of a bytes instance.
2015
Christian Heimesa872de52008-12-05 08:26:55 +00002016- Issue #4533: File read operation was dreadfully slow due to a slowly
2017 growing read buffer. Fixed by using the same growth rate algorithm as
2018 Python 2.x.
2019
Antoine Pitrou5504e892008-12-06 21:27:53 +00002020- Issue #4509: Various issues surrounding resize of bytearray objects to
2021 which there are buffer exports (e.g. memoryview instances).
2022
Georg Brandlf9734072008-12-07 15:30:06 +00002023- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2024 method on file objects with closefd=False. The file descriptor is still
2025 kept open but the file object behaves like a closed file. The ``FileIO``
2026 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002027
Antoine Pitroubc420402008-12-07 20:14:49 +00002028- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2036 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2037 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2038 of using the replace error handler in PyUnicode_DecodeUTF8().
