Victor Stinner9ca9c252010-05-19 16:53:30 +000015- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
16 encoding and surrogateespace error handler instead of the locale encoding to
17 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
18
Victor Stinner372ac5e2010-05-17 01:26:01 +000019- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
20 (instead of strict) error handler to escape surrogates
21

23 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000024 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
25 back to UTF-8.

29
Victor Stinnerb744ba12010-05-15 12:27:16 +000030- Issue #8610: Load file system codec at startup, and display a fatal error on
31 failure. Set the file system encoding to utf-8 (instead of None) if getting
32 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
33
Victor Stinner0964ee12010-04-30 16:48:45 +000034- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
35 PyUnicode_FromString() to support surrogates in the filename and use the
36 right encoding
37
Victor Stinnerb9a20ad2010-04-30 16:37:52 +000038- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
39

41 arguments.
42
Victor Stinner14284c22010-04-23 12:02:30 +000043- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
44 indirectly Python signal handlers anymore because mywrite() ignores
45 exceptions (KeyboardInterrupt)
46
Victor Stinner31be90b2010-04-22 19:38:16 +000047- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing

51 you have to convert your bytearray filenames to bytes
52
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +000053- Issue #7332: Remove the 16KB stack-based buffer in
54 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
55 benefit compared to the dynamic memory allocation fallback. Patch by
56 Charles-François Natali.
57
Benjamin Peterson8380dd52010-04-16 22:51:37 +000058- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
59 passed to bytes or bytearray.
60
Philip Jenvey0805ca32010-04-07 04:04:10 +000061- Issue #7301: Add environment variable $PYTHONWARNINGS.
62
Benjamin Petersond856ab62010-04-06 21:55:16 +000063- Issue #8329: Don't return the same lists from select.select when no fds are

65
Mark Dickinson3318d292010-04-06 16:53:17 +000066- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
67 on 64-bit machines. The shift count for either left or right shift is
68 permitted to be up to sys.maxsize.
69
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000070- Ensure that tokenization of identifiers is not affected by locale.

85 PyMemberDefs could produce an internal error; raise TypeError instead.
86
Mark Dickinsonf673f0c2010-03-13 09:48:39 +000087- Issue #7845: Rich comparison methods on the complex type now return
88 NotImplemented rather than raising a TypeError when comparing with an
89 incompatible type; this allows user-defined classes to implement their own
90 comparisons with complex.
91
Victor Stinner52f6dd72010-03-12 14:45:56 +000092- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt

123 deprecations.
124
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000125- Issue #7385: Fix a crash in `MemoryView_FromObject` when
126 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
127
Mark Dickinsonbc099642010-01-29 17:27:24 +0000128- Issue #7788: Fix an interpreter crash produced by deleting a list
129 slice with very large step value.
130
Eric Smithf7bb5782010-01-27 00:44:57 +0000131- Issue #7766: Change sys.getwindowsversion() return value to a named
132 tuple and add the additional members returned in an OSVERSIONINFOEX

134 suite_mask, and product_type.
135
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000136- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
137 could crash in many places because of the PyByteArray_AS_STRING() macro
138 returning NULL. The macro now returns a statically allocated empty
139 string instead.
140
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000141- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
142 where the right hand operand is a set of constants, by turning the set into
143 a frozenset and pre-building it as a constant. The comparison operation
144 is made against the constant instead of building a new set each time it is
145 executed (a similar optimization already existed which turned a list of
146 constants into a pre-built tuple). Patch and additional tests by Dave
147 Malcolm.
148
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000149- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

154 alpha 2, including: (1) a serious 'wrong output' bug that could
155 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
156 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000157 strings corresponding to subnormal values, (3) a memory leak for
158 some values large enough to cause overflow, and (4) a number of
159 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000160
Benjamin Petersonaea44282010-01-04 01:10:28 +0000161- The __complex__ method is now looked up on the class of instances to make it

172 described in C99 Annex F.
173
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000174- Issue #1811: improve accuracy and cross-platform consistency for
175 true division of integers: the result of a/b is now correctly
176 rounded for ints a and b (at least on IEEE 754 platforms), and in
177 particular does not depend on the internal representation of an int.
178
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000179- Issue #6834: replace the implementation for the 'python' and 'pythonw'
180 executables on OSX.
181

Mark Dickinsond550c9a2009-11-15 09:57:26 +0000203- Issue #7298: fixes for range and reversed(range(...)). Iteration
204 over range(a, b, c) incorrectly gave an empty iterator when a, b and
205 c fit in C long but the length of the range did not. Also fix

318
Benjamin Petersonfb886362010-04-24 18:21:17 +0000319- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
320 strings in an efficient manner.
321
Antoine Pitrou8689a102010-04-01 16:53:15 +0000322- Issue #8276: PyEval_CallObject() is now only available in macro form. The
323 function declaration, which was kept for backwards compatibility reasons,
324 is now removed (the macro was introduced in 1997!).
325
Mark Dickinson93f562c2010-01-30 10:30:15 +0000326- Issue #7767: New function PyLong_AsLongLongAndOverflow added,
327 analogous to PyLong_AsLongAndOverflow.
328
Benjamin Peterson8667a9b2010-01-09 21:45:28 +0000329- Make PyUnicode_CompareWithASCIIString return not equal if the Python string
330 has '\0' at the end.
331
Mark Dickinsonde604012010-01-01 19:27:32 +0000332- Issue #5080: The argument parsing functions PyArg_ParseTuple,
333 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
334 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
335 DeprecationWarning for float arguments passed with the 'L' format
336 code. This will become a TypeError in a future version of Python,
337 to match the behaviour of the other integer format codes.
338
Georg Brandl1e28a272009-12-28 08:41:01 +0000339- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.
340
Mark Dickinsonf08173b2009-12-03 10:59:46 +0000341- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments)
342 in PyArg_ParseTupleAndKeywords.
343
Mark Dickinson0b2b2322009-12-04 11:32:26 +0000344- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V)
Mark Dickinson6ce4a9a2009-11-16 17:00:11 +0000345 and PyErr_Format, on machines with HAVE_LONG_LONG defined.
346
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000347- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
348 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
349 should used for accessing the d_type and d_name members of structures
350 using PyDescr_COMMON.
351
352- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000353

357 PyCode_Addr2Line().
358
359- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
360 object at a specified file, function, and line number.
361
362- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
363 ``const char *`` as the string is stored beyond the call.
364
Benjamin Peterson05159c42009-12-03 03:01:27 +0000365- Issue #2422: When compiled with the ``--with-valgrind`` option, the
366 pymalloc allocator will be automatically disabled when running under
367 Valgrind. This gives improved memory leak detection when running
368 under Valgrind, while taking advantage of pymalloc at other times.

Victor Stinner2ca03c12010-05-19 17:00:07 +0000373- Issue #8663: distutils.log emulates backslashreplace error handler. Fix
374 compilation in a non-ASCII directory if stdout encoding is ASCII (eg. if
375 stdout is not a TTY).
376
Victor Stinnerb745a742010-05-18 17:17:23 +0000377- Issue #8513: os.get_exec_path() supports b'PATH' key and bytes value.
378 subprocess.Popen() and os._execvpe() support bytes program name. Add
379 os.supports_bytes_environ flag: True if the native OS type of the environment
380 is bytes (eg. False on Windows).
381
Lars Gustäbel1465cc22010-05-17 18:02:50 +0000382- Issue #8633: tarfile is now able to read and write archives with "raw" binary

396 the zlib itself doesn't give any detailed explanation.
397
Mark Dickinson81fece22010-05-11 13:34:35 +0000398- The audioop module now supports sound fragments of length greater
399 than 2**31 bytes on 64-bit machines, and is PY_SSIZE_T_CLEAN.
400
Giampaolo Rodolàbd576b72010-05-10 14:53:29 +0000401- Issue #4972: Add support for the context manager protocol to the ftplib.FTP
402 class.

405 given.
406
Victor Stinner449c4662010-05-08 11:10:09 +0000407- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
408 for use in the file system, environment variables or the command line.
409
Antoine Pitrou89562712010-05-07 17:04:02 +0000410- Issue #8571: Fix an internal error when compressing or decompressing a

412 objects.
413
Benjamin Peterson225168e2010-05-06 22:29:53 +0000414- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
415 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
416 file system encoding with the surrogateescape error handler (instead of
417 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
Victor Stinner84ae1182010-05-06 22:05:07 +0000418
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000419- Issue #8573: asyncore _strerror() function might throw ValueError.
420
Victor Stinnere125f132010-05-15 21:04:43 +0000421- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
422 error messages when accessing undefined class attributes because of the cheap
423 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000424 The cheap inheritance has been deprecated.
425
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000426- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
427 Patch by Tres Seaver.
428
Victor Stinnerde629d42010-05-05 21:43:57 +0000429- Issue #8390: tarfile uses surrogateespace as the default error handler
430 (instead of replace in read mode or strict in write mode)
431

436
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000437- Issue #8567: Fix precedence of signals in Decimal module: when a
438 Decimal operation raises multiple signals and more than one of those
439 signals is trapped, the specification determines the order in which
440 the signals should be handled. In many cases this order wasn't
441 being followed, leading to the wrong Python exception being raised.
442
Antoine Pitrou6be88762010-05-03 16:48:20 +0000443- Issue #7865: The close() method of :mod:`io` objects should not swallow
444 exceptions raised by the implicit flush(). Also ensure that calling
445 close() several times is supported. Patch by Pascal Chambon.
446
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000447- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
448 gc.DEBUG_STATS.
449
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000450- Issue #8354: The siginterrupt setting is now preserved for all signals,
451 not just SIGCHLD.
452
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000453- Issue #7192: webbrowser.get("firefox") now wors on Mac OS X, as does
454 webbrowser.get("safari").

471
R. David Murrayad78d152010-04-27 02:45:53 +0000472- Issue #6656: fix locale.format_string to handle escaped percents
473 and mappings.
474
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000475- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
476 where the method could block indefinitely if called just before the
477 event loop started running. This also fixes the occasional freezes
478 witnessed in test_httpservers.
479
Antoine Pitrou40f08742010-04-24 22:04:40 +0000480- Issue #8524: When creating an SSL socket, the timeout value of the
481 original socket wasn't retained (instead, a socket with a positive timeout
482 would be turned into a non-blocking SSL socket).
483
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000484- Issue #5103: SSL handshake would ignore the socket timeout and block
485 indefinitely if the other end didn't respond.
486
487- The do_handshake() method of SSL objects now adjusts the blocking mode of
488 the SSL structure if necessary (as other methods already do).
489
Victor Stinner13bb71c2010-04-23 21:41:56 +0000490- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
491 and bytes strings for environment keys and values
492
Victor Stinner4d078042010-04-23 19:28:32 +0000493- Issue #8467: Pure Python implementation of subprocess encodes the error

498
Sean Reifscheider13daf122010-04-23 09:29:52 +0000499- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
500 the string "python" as the *ident*. openlog() arguments are all optional
501 and keywords.
502
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000503- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
504 a non-infinite timeout. Also make that method friendlier with applications
505 wanting to continue using the socket in clear-text mode, by disabling
506 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
507
Antoine Pitrou7062db82010-04-22 13:30:10 +0000508- Issue #8496: make mailcap.lookup() always return a list, rather than an

Antoine Pitroufec12ff2010-04-21 19:46:23 +0000514- Issue #8484: Load all ciphers and digest algorithms when initializing
515 the _ssl extension, such that verification of some SSL certificates
516 doesn't fail because of an "unknown algorithm".
517
Tarek Ziadéfb437512010-04-20 08:57:33 +0000518- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.

524 from PORT/EPRT commands.
525
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000526- Issue #8463: added missing reference to bztar in shutil's documentation.
527

529 (as long as the user didn't specify 'automatic proxy configuration').
530
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000531- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
532 code as stated in RFC-959 at chapter 5.4.
533
Victor Stinner738446f02010-04-18 00:00:44 +0000534- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
535 surrogates.
536
Antoine Pitrou0454af92010-04-17 23:51:58 +0000537- Issue #850728: Add a *timeout* parameter to the `acquire()` method of

544 the current working directory.
545
Victor Stinner5bfe1462010-04-16 13:28:05 +0000546- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
547 using backslashreplace error handler

556
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000557- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
558 module now takes an optional timeout argument in seconds. Timeout support
559 relies on the system threading library, so as to avoid a semi-busy wait
560 loop.
561
Victor Stinner485fb562010-04-13 11:07:24 +0000562- Issue #8383: pickle and pickletools use surrogatepass error handler when

564 Python 2.x and 3.0
565
R. David Murrayb2416e52010-04-12 16:58:02 +0000566- Issue #7585: difflib context and unified diffs now place a tab between
567 filename and date, conforming to the 'standards' they were originally
568 designed to follow. This improves compatibility with patch tools.
569
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000570- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
571 character sets will now consistently use a Content-Transfer-Encoding of
572 7bit rather than sometimes being marked as 8bit.
573
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000574- Issue #8375: test_distutils now checks if the temporary directory are still
575 present before it cleans them.
576
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000577- Issue #8374: Update the internal alias table in the :mod:`locale` module
578 to cover recent locale changes and additions.

581 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
582 and `ssl.OPENSSL_VERSION_NUMBER`.
583
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000584- Add functools.total_ordering() and functools.cmp_to_key().
585
Mark Dickinson089b00c2010-04-03 15:51:03 +0000586- Issue #8257: The Decimal construct now accepts a float instance
587 directly, converting that float to a Decimal of equal value:
588
589 >>> Decimal(1.1)
590 Decimal('1.100000000000000088817841970012523233890533447265625')
591
Mark Dickinson98127c32010-04-03 11:18:52 +0000592- Issue #8294: The Fraction constructor now accepts Decimal and float
593 instances directly.
594
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000595- Issue #7279: Comparisons involving a Decimal signaling NaN now
596 signal InvalidOperation instead of returning False. (Comparisons
597 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
598 are now hashable; Decimal signaling NaNs remain unhashable.
599
600- Issue #2531: Comparison operations between floats and Decimal
601 instances now return a result based on the numeric values of the
602 operands; previously they returned an arbitrary result based on
603 the relative ordering of id(float) and id(Decimal).
604
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000605- Added a subtract() method to collections.Counter().
606
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000607- Issue #8233: When run as a script, py_compile.py optionally takes a single
608 argument `-` which tells it to read files to compile from stdin. Each line
609 is read on demand and the named file is compiled immediately. (Original
610 patch by Piotr Ożarowski).

664 by an extension module (_posixsubprocess) so that the fork()+exec() can be
665 done safely without the possibility of deadlock in multithreaded applications.
666
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000667- subprocess.Popen now has restore_signals and start_new_session features.
668 The default of restore_signals=True is a new behavior compared to earlier
669 Python versions. This means that signals such as SIGPIPE are not ignored
670 by default in subprocesses launched by Python (Issue #1652).
671
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000672- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

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

766 It also solves an issue where interleaved calls to `read()` and
767 `readline()` give wrong results. Patch by Nir Aides.

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000930- Issue #6816: runpy now provides a run_path function that allows Python code
931 to execute file paths that refer to source or compiled Python files as well
932 as zipfiles, directories and other valid sys.path entries that contain a

Victor Stinnere125f132010-05-15 21:04:43 +0000953 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +0000954 recursive locks as fast as regular non-recursive locks (previously,

1241 gcc. (Optimization was unintentionally turned on in gcc

R. David Murrayba311052009-12-04 00:09:14 +00001400 file in the Lib/test directory, which might be read-only for the
1401 user running the tests.
1402
R. David Murray35768ad2009-11-15 00:23:21 +00001403- Issue #7324: add a sanity check to regrtest argument parsing to

Antoine Pitrou65c9c642009-10-30 17:25:12 +00001427- Issue #7222: Make thread "reaping" more reliable so that reference
1428 leak-chasing test runs give sensible results. The previous method of
1429 reaping threads could return successfully while some Thread objects were
1430 still referenced. This also introduces a new private function:
1431 :func:`_thread._count()`.

1434 longer runs the risk of causing the worker thread to fail.
1435
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001436- Issue #7055: test___all__ now greedily detects all modules which have an

1441 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001442
Mark Dickinson2e304402009-10-04 18:43:54 +00001443- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.

1446 the proper exceptions that should be raised for missing or improper code
1447 object bytecode.

1734 default precision of 12. Previously, the behavior the same but with
1735 a default precision of 6. This more closely matches str(), and
1736 reduces surprises when adding alignment flags to the empty

1738 the same way.

1778
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001779- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001780
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001781- Issue #1869 (and many duplicates): make round(x, n) correctly
1782 rounded for a float x, by using the decimal <-> binary conversions
1783 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1784 consistently agrees with format(x, '.2f').
1785
Benjamin Petersonae937c02009-04-18 20:54:08 +00001786- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

1788
Eric Smith0923d1d2009-04-16 20:16:10 +00001789- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1790
Eric Smith35e84722009-04-16 20:21:28 +00001791- Issue #5515: str.format() type 'n' combined with commas and leading
1792 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001793
1794- Implement PEP 378, Format Specifier for Thousands Separator, for
1795 floats.
1796
Mark Dickinson3370cce2009-04-17 22:40:53 +00001797- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001798 1e11, not 1e12. This avoids printing 13 significant digits in
1799 situations where only 12 of them are correct. Example problem
1800 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1801 long time.)
1802
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001803- Issue #1580: On most platforms, use a 'short' float repr: for a
1804 finite float x, repr(x) now outputs a string based on the shortest
1805 sequence of decimal digits that rounds to x. Previous behaviour was
1806 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001807 Another minor difference is that the new repr switches to
1808 exponential notation at 1e16 instead of the previous 1e17; this
1809 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001810
1811 There's a new sys attribute sys.float_repr_style, which takes
1812 the value 'short' to indicate that we're using short float repr,
1813 and 'legacy' if the short float repr isn't available for one
1814 reason or another.
1815
1816 The float repr change involves incorporating David Gay's 'perfect
1817 rounding' code into the Python core (it's in Python/dtoa.c). As a
1818 secondary consequence, all string-to-float and float-to-string
1819 conversions (including all float formatting operations) will be
1820 correctly rounded on these platforms.
1821
1822 See issue 1580 discussions for details of platforms for which
1823 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001825- Issue #5759: float() didn't call __float__ on str subclasses.
1826
Georg Brandlabc38772009-04-12 15:51:51 +00001827- The string.maketrans() function is deprecated; there is a new static method
1828 maketrans() on the bytes and bytearray classes. This removes confusion about
1829 the types string.maketrans() is supposed to work with, and mirrors the
1830 methods available on the str class.

Lars Gustäbel42e00912009-03-22 20:34:29 +00002069- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2070 forever on incomplete input. That caused tarfile.open() to hang when used
2071 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2072 partial bzip2 compressed data.
2073
Mark Dickinson79f52032009-03-17 23:12:51 +00002074- Issue #2110: Add support for thousands separator and 'n' type

2078 '>' alignment characters.
2079
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00002080- The error detection code in FileIO.close() could fail to reflect the `errno`
2081 value, and report it as -1 instead.
2082
Antoine Pitroua28fcfd2009-03-13 23:42:55 +00002083- Issue #5016: FileIO.seekable() could return False if the file position

2092 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00002093 struct.error instead of returning b'\xff\xff\xff\xff'. The
2094 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2095 have been removed from the struct module.

2118
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002119- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2120 rotating the object pointer by 4 bits to the right.
2121
Mark Dickinson87ec0852009-02-09 17:15:59 +00002122- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2123 it now forces its argument to double before testing for infinity.
2124
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002125- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

2133 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002134
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002135- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002136 were suppressing all exceptions. These include list() and bytearray().
2137
Mark Dickinson1124e712009-01-28 21:25:58 +00002138- Issue #4707: round(x, n) now returns an integer if x is an integer.
2139 Previously it returned a float.
2140
Antoine Pitroub52ec782009-01-25 16:34:23 +00002141- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2142 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2143 evaluation loop is compiled with a new dispatch mechanism which gives
2144 speedups of up to 20%, depending on the system, on various benchmarks.
2145
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002146- Issue #4874: Most builtin decoders now reject unicode input.

2152
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002153- Issue #4838: When a module is deallocated, free the memory backing the
2154 optional module state data.
2155
Mark Dickinson8055afd2009-01-17 10:04:45 +00002156- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2157 type to (void *).
2158
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002159- Issue #4935: The overflow checking code in the expandtabs() method common
2160 to str, bytes and bytearray could be optimized away by the compiler, letting
2161 the interpreter segfault instead of raising an error.
2162
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002163- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2164 __next__ method.
2165
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002166- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2167 function no longer attempt to call the __long__ slot to convert an object
2168 to an integer. Only the __int__ and __trunc__ slots are examined.
2169
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002170- Issue #4893: Use NT threading on CE.
2171
Martin v. Löwisec59d042009-01-12 07:59:10 +00002172- Issue #4915: Port sysmodule to Windows CE.
2173
Antoine Pitrouab868312009-01-10 15:40:25 +00002174- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2175 common cases are optimized thanks to a dedicated fast path and a moderate
2176 amount of loop unrolling.
2177
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002178- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2179 collecting the oldest generation) so that allocating lots of objects without
2180 destroying them does not show quadratic performance. Based on a proposal by
2181 Martin von Löwis at
2182 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2183
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002184- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002185 having been closed (for instance, a read() call could return some
2186 previously buffered data). Patch by Dmitry Vasiliev.
2187
Antoine Pitrou05608432009-01-09 18:53:14 +00002188- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2189 flag to work properly. Furthermore, when specifying -u, the text stdout
2190 and stderr streams have line-by-line buffering enabled (the default being
2191 to buffer arbitrary chunks of data).
2192
Raymond Hettinger35631532009-01-09 03:58:09 +00002193- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2194 instead of ints (reducing its size from 4 to 8 times thereby reducing
2195 Python's overall memory).
2196
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002197- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2198 an existing .py counterpart, override the co_filename attributes of all
2199 code objects if the original filename is obsolete (which can happen if the
2200 file has been renamed, moved, or if it is accessed through different paths).
2201 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2202
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002203- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2204 one byte. Also fixes the meaning of len() so that it returns the number of
2205 items, rather than the size in bytes.
2206
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002207- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2208
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002209- Issue #4747: When the terminal does not use utf-8, executing a script with
2210 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2211
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002212- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002213 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002214
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002215- Issue #3680: Reference cycles created through a dict, set or deque iterator
2216 did not get collected.
2217
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002218- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2219 where the tp_hash and tp_dict slots are both NULL.
2220
Georg Brandlccc47b62008-12-28 11:44:14 +00002221- Issue #4759: None is now allowed as the first argument of
2222 bytearray.translate(). It was always allowed for bytes.translate().
2223
Skip Montanaro80072cb2008-12-23 03:51:14 +00002224- Added test case to ensure attempts to read from a file opened for writing
2225 fail.
2226
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002227- Issue #3106: Speedup some comparisons (str/str and int/int).

2231
Antoine Pitrou621601a2008-12-17 23:18:19 +00002232- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2233 print elapsed times, not only when some objects are uncollectable /
2234 unreachable. Original patch by Neil Schemenauer.
2235
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002236- Issue #3439: Add a bit_length method to int.
2237
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002238- Issue #2173: When getting device encoding, check that return value of
2239 nl_langinfo is not the empty string. This was causing silent build
2240 failures on OS X.
2241
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002242- Issue #4597: Fixed several opcodes that weren't always propagating
2243 exceptions.
2244
2245- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002246 context manager returns a value that cannot be converted to a bool.
2247
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002248- Issue #4445: Replace "sizeof(PyBytesObject)" with
2249 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2250 bytes instances. On a typical machine this saves 3 bytes of memory
2251 (on average) per allocation of a bytes instance.
2252
Christian Heimesa872de52008-12-05 08:26:55 +00002253- Issue #4533: File read operation was dreadfully slow due to a slowly
2254 growing read buffer. Fixed by using the same growth rate algorithm as
2255 Python 2.x.
2256
Antoine Pitrou5504e892008-12-06 21:27:53 +00002257- Issue #4509: Various issues surrounding resize of bytearray objects to
2258 which there are buffer exports (e.g. memoryview instances).
2259
Georg Brandlf9734072008-12-07 15:30:06 +00002260- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2261 method on file objects with closefd=False. The file descriptor is still
2262 kept open but the file object behaves like a closed file. The ``FileIO``
2263 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002264
Antoine Pitroubc420402008-12-07 20:14:49 +00002265- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2271
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002272- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2273 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2274 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2275 of using the replace error handler in PyUnicode_DecodeUTF8().
