Benjamin Peterson46ea4f72009-06-27 21:40:27 +00007What's New in Python 3.2 Alpha 1?
8=================================
9
10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Victor Stinner313a1202010-06-11 23:56:51 +000015- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
16 filenames and enable os.fsencode().
17
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000018- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
19 the interpreter with characters outside the Basic Multilingual Plane
20 (higher than 0x10000).
21
Mark Dickinsonc7301312010-06-10 16:05:10 +000022- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
23 raise TypeError instead of giving a DeprecationWarning when a float
24 is parsed using the 'L' code (for long long). (All other integer
25 codes already raise TypeError in this case.)
26
Victor Stinner600d3be2010-06-10 12:00:55 +000027- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
28 enable shortcuts for upper case encoding name. Add also a shortcut for
29 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
30
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000031- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
32 doesn't support "char buffer" anymore in Python3.
33
34- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
35 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
36 like bytearray.
37
Victor Stinner33109a12010-05-28 21:55:10 +000038- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
39 used anymore and it was never documented.
40
Benjamin Peterson95304522010-06-08 14:57:22 +000041- In the str.format(), raise a ValueError when indexes to arguments are too
42 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000043
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000044- Issue #2844: Make int('42', n) consistently raise ValueError for
45 invalid integers n (including n = -909).
46
Mark Dickinsondc787d22010-05-23 13:33:13 +000047- Issue #8188: Introduce a new scheme for computing hashes of numbers
48 (instances of int, float, complex, decimal.Decimal and
49 fractions.Fraction) that makes it easy to maintain the invariant
50 that hash(x) == hash(y) whenever x and y have equal value.
51
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000052- Issue #8748: Fix two issues with comparisons between complex and integer
53 objects. (1) The comparison could incorrectly return True in some cases
54 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
55 (2) The comparison raised an OverflowError for large integers, leading
56 to unpredictable exceptions when combining integers and complex objects
57 in sets or dicts.
58
Victor Stinner7d79b8b2010-05-19 20:40:50 +000059- Issue #8766: Initialize _warnings module before importing the first module.
60 Fix a crash if an empty directory called "encodings" exists in sys.path.
61
Victor Stinner9ca9c252010-05-19 16:53:30 +000062- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
63 encoding and surrogateespace error handler instead of the locale encoding to
64 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
65
Victor Stinner372ac5e2010-05-17 01:26:01 +000066- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
67 (instead of strict) error handler to escape surrogates
68
Victor Stinnerae6265f2010-05-15 16:27:27 +000069- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
70 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000071 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
72 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +000073
Victor Stinner59e62db2010-05-15 13:14:32 +000074- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
75 error handler, not only the default error handler (strict)
76
Victor Stinnerb744ba12010-05-15 12:27:16 +000077- Issue #8610: Load file system codec at startup, and display a fatal error on
78 failure. Set the file system encoding to utf-8 (instead of None) if getting
79 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
80
Victor Stinner0964ee12010-04-30 16:48:45 +000081- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
82 PyUnicode_FromString() to support surrogates in the filename and use the
83 right encoding
84
Georg Brandl8569e582010-05-19 20:57:08 +000085- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
86
Victor Stinnerb9a20ad2010-04-30 16:37:52 +000087- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
88
Benjamin Petersonfb886362010-04-24 18:21:17 +000089- Issue #8419: Prevent the dict constructor from accepting non-string keyword
90 arguments.
91
Victor Stinner14284c22010-04-23 12:02:30 +000092- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
93 indirectly Python signal handlers anymore because mywrite() ignores
94 exceptions (KeyboardInterrupt)
95
Victor Stinner31be90b2010-04-22 19:38:16 +000096- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
97 unicode string (eg. backslashreplace)
98
Victor Stinnerdcb24032010-04-22 12:08:36 +000099- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
100 you have to convert your bytearray filenames to bytes
101
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000102- Issue #7332: Remove the 16KB stack-based buffer in
103 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
104 benefit compared to the dynamic memory allocation fallback. Patch by
105 Charles-François Natali.
106
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000107- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
108 passed to bytes or bytearray.
109
Philip Jenvey0805ca32010-04-07 04:04:10 +0000110- Issue #7301: Add environment variable $PYTHONWARNINGS.
111
Benjamin Petersond856ab62010-04-06 21:55:16 +0000112- Issue #8329: Don't return the same lists from select.select when no fds are
113 changed.
114
Mark Dickinson3318d292010-04-06 16:53:17 +0000115- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
116 on 64-bit machines. The shift count for either left or right shift is
117 permitted to be up to sys.maxsize.
118
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000119- Ensure that tokenization of identifiers is not affected by locale.

126 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000127
Victor Stinner120c2122010-03-25 00:30:28 +0000128- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
129 is unknown
130
Victor Stinner808fc0a2010-03-22 12:50:40 +0000131- Issue #1583863: An str subclass can now override the __str__ method
132
Mark Dickinsond59b4162010-03-13 11:34:40 +0000133- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
134 PyMemberDefs could produce an internal error; raise TypeError instead.
135
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000136- Issue #7845: Rich comparison methods on the complex type now return
137 NotImplemented rather than raising a TypeError when comparing with an
138 incompatible type; this allows user-defined classes to implement their own
139 comparisons with complex.
140
Victor Stinner52f6dd72010-03-12 14:45:56 +0000141- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
142 (SIGINT). If an error occurs while importing the site module, the error is
143 printed and Python exits. Initialize the GIL before importing the site
144 module.
145
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000146- Issue #7173: Generator finalization could invalidate sys.exc_info().

155
Larry Hastings1373a072010-02-24 22:49:58 +0000156- Issue #5939: Add additional runtime checking to ensure a valid capsule
157 in Modules/_ctypes/callproc.c.
158
Eric Smith0facd772010-02-24 15:42:29 +0000159- Issue #7309: Fix unchecked attribute access when converting
160 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
161 strings.
162

170 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
171 and PyOS_string_to_double instead. See issue #5835 for the original
172 deprecations.
173
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000174- Issue #7385: Fix a crash in `MemoryView_FromObject` when
175 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
176
Mark Dickinsonbc099642010-01-29 17:27:24 +0000177- Issue #7788: Fix an interpreter crash produced by deleting a list
178 slice with very large step value.
179
Eric Smithf7bb5782010-01-27 00:44:57 +0000180- Issue #7766: Change sys.getwindowsversion() return value to a named
181 tuple and add the additional members returned in an OSVERSIONINFOEX
182 structure. The new members are service_pack_major, service_pack_minor,
183 suite_mask, and product_type.
184
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000185- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
186 could crash in many places because of the PyByteArray_AS_STRING() macro
187 returning NULL. The macro now returns a statically allocated empty
188 string instead.
189
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000190- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
191 where the right hand operand is a set of constants, by turning the set into
192 a frozenset and pre-building it as a constant. The comparison operation
193 is made against the constant instead of building a new set each time it is
194 executed (a similar optimization already existed which turned a list of
195 constants into a pre-built tuple). Patch and additional tests by Dave
196 Malcolm.
197
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000198- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
199 methods of bytes, bytearray and unicode objects by using a common
200 implementation based on stringlib's fast search. Patch by Florent Xicluna.

203 alpha 2, including: (1) a serious 'wrong output' bug that could
204 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
205 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000206 strings corresponding to subnormal values, (3) a memory leak for
207 some values large enough to cause overflow, and (4) a number of
208 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000209
Benjamin Petersonaea44282010-01-04 01:10:28 +0000210- The __complex__ method is now looked up on the class of instances to make it

218
Mark Dickinson9ab44b52009-12-30 16:22:49 +0000219- Issue #7534: Fix handling of IEEE specials (infinities, nans,
220 negative zero) in ** operator. The behaviour now conforms to that
221 described in C99 Annex F.
222
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000223- Issue #1811: improve accuracy and cross-platform consistency for
224 true division of integers: the result of a/b is now correctly
225 rounded for ints a and b (at least on IEEE 754 platforms), and in
226 particular does not depend on the internal representation of an int.
227
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000228- Issue #6834: replace the implementation for the 'python' and 'pythonw'
229 executables on OSX.
230
231 These executables now work properly with the arch(1) command:
232 ``arch -ppc python`` will start a universal binary version of python
233 in PPC mode (unlike previous releases).
234
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000235- Issue #7466: segmentation fault when the garbage collector is called

243
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000244- Issue #7085: Fix crash when importing some extensions in a thread
245 on MacOSX 10.6.
246

251
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000252- Issue #7298: fixes for range and reversed(range(...)). Iteration
253 over range(a, b, c) incorrectly gave an empty iterator when a, b and
254 c fit in C long but the length of the range did not. Also fix
255 several cases where reversed(range(a, b, c)) gave wrong results, and
256 fix a refleak for reversed(range(a, b, c)) with large arguments.
257
Raymond Hettingerfc438512009-11-01 20:55:33 +0000258- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Antoine Pitrouf978fac2010-05-21 17:25:34 +0000368- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
369 embedders of the interpreter to set sys.argv without also modifying
370 sys.path. This helps fix `CVE-2008-5983
371 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
372

Mark Dickinsonde604012010-01-01 19:27:32 +0000386- Issue #5080: The argument parsing functions PyArg_ParseTuple,
387 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
388 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
389 DeprecationWarning for float arguments passed with the 'L' format
390 code. This will become a TypeError in a future version of Python,
391 to match the behaviour of the other integer format codes.
392

402 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
403 should used for accessing the d_type and d_name members of structures
404 using PyDescr_COMMON.

418
Benjamin Peterson05159c42009-12-03 03:01:27 +0000419- Issue #2422: When compiled with the ``--with-valgrind`` option, the
420 pymalloc allocator will be automatically disabled when running under
421 Valgrind. This gives improved memory leak detection when running
422 under Valgrind, while taking advantage of pymalloc at other times.

Mark Dickinson08ade6f2010-06-11 10:44:52 +0000433 now permitted, returning a result based on the exact numerical
434 values of the operands. This builds on issue #2531, which allowed
435 Decimal-to-float comparisons; all comparisons involving numeric
436 types (bool, int, float, complex, Decimal, Fraction) should now
437 act as expected.

610 event loop started running. This also fixes the occasional freezes
611 witnessed in test_httpservers.
612
Antoine Pitrou40f08742010-04-24 22:04:40 +0000613- Issue #8524: When creating an SSL socket, the timeout value of the
614 original socket wasn't retained (instead, a socket with a positive timeout
615 would be turned into a non-blocking SSL socket).
616
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000617- Issue #5103: SSL handshake would ignore the socket timeout and block
618 indefinitely if the other end didn't respond.
619
620- The do_handshake() method of SSL objects now adjusts the blocking mode of
621 the SSL structure if necessary (as other methods already do).
622
Victor Stinner13bb71c2010-04-23 21:41:56 +0000623- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
624 and bytes strings for environment keys and values
625
Victor Stinner4d078042010-04-23 19:28:32 +0000626- Issue #8467: Pure Python implementation of subprocess encodes the error
627 message using surrogatepass error handler to support surrogates in the
628 message
629
Victor Stinner349fd522010-04-23 10:56:17 +0000630- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
631
Sean Reifscheider13daf122010-04-23 09:29:52 +0000632- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
633 the string "python" as the *ident*. openlog() arguments are all optional
634 and keywords.
635
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000636- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
637 a non-infinite timeout. Also make that method friendlier with applications
638 wanting to continue using the socket in clear-text mode, by disabling
639 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
640
Antoine Pitrou7062db82010-04-22 13:30:10 +0000641- Issue #8496: make mailcap.lookup() always return a list, rather than an
642 iterator. Patch by Gregory Nofi.
643
Victor Stinner35466c52010-04-22 11:23:23 +0000644- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
645 collation name contains a surrogate character.
646
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000647- Issue #8484: Load all ciphers and digest algorithms when initializing
648 the _ssl extension, such that verification of some SSL certificates
649 doesn't fail because of an "unknown algorithm".
650
Tarek Ziadéfb437512010-04-20 08:57:33 +0000651- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
652
Victor Stinnere125f132010-05-15 21:04:43 +0000653- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000654 shutil.copytree.
655
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000656- Issue #4814: timeout parameter is now applied also for connections resulting
657 from PORT/EPRT commands.
658
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000659- Issue #8463: added missing reference to bztar in shutil's documentation.
660
Ronald Oussoren84151202010-04-18 20:46:11 +0000661- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
662 (as long as the user didn't specify 'automatic proxy configuration').
663
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000664- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
665 code as stated in RFC-959 at chapter 5.4.
666
Victor Stinner738446f02010-04-18 00:00:44 +0000667- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
668 surrogates.
669
Antoine Pitrou0454af92010-04-17 23:51:58 +0000670- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000671 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000672
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000673- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
674 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
675
Victor Stinner0e59cc32010-04-16 23:49:32 +0000676- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
677 the current working directory.
678
Victor Stinner5bfe1462010-04-16 13:28:05 +0000679- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
680 using backslashreplace error handler
681
Victor Stinnercfa72782010-04-16 11:45:13 +0000682- Issue #8412: os.system() now accepts bytes, bytearray and str with
683 surrogates.

Senthil Kumaranad02d232010-04-16 03:02:13 +0000685- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
686 Locke and Hans Ulrich Niedermann.
687
R. David Murrayd48739f2010-04-14 18:59:18 +0000688- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
689
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000690- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
691 module now takes an optional timeout argument in seconds. Timeout support
692 relies on the system threading library, so as to avoid a semi-busy wait
693 loop.
694
Victor Stinner485fb562010-04-13 11:07:24 +0000695- Issue #8383: pickle and pickletools use surrogatepass error handler when
696 encoding unicode as utf8 to support lone surrogates and stay compatible with
697 Python 2.x and 3.0
698
R. David Murrayb2416e52010-04-12 16:58:02 +0000699- Issue #7585: difflib context and unified diffs now place a tab between
700 filename and date, conforming to the 'standards' they were originally
701 designed to follow. This improves compatibility with patch tools.
702
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000703- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
704 character sets will now consistently use a Content-Transfer-Encoding of
705 7bit rather than sometimes being marked as 8bit.
706
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000707- Issue #8375: test_distutils now checks if the temporary directory are still
708 present before it cleans them.
709
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000710- Issue #8374: Update the internal alias table in the :mod:`locale` module
711 to cover recent locale changes and additions.
712
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000713- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
714 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
715 and `ssl.OPENSSL_VERSION_NUMBER`.
716
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000717- Add functools.total_ordering() and functools.cmp_to_key().
718
Mark Dickinson089b00c2010-04-03 15:51:03 +0000719- Issue #8257: The Decimal construct now accepts a float instance
720 directly, converting that float to a Decimal of equal value:
721
722 >>> Decimal(1.1)
723 Decimal('1.100000000000000088817841970012523233890533447265625')
724
Mark Dickinson98127c32010-04-03 11:18:52 +0000725- Issue #8294: The Fraction constructor now accepts Decimal and float
726 instances directly.
727
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000728- Issue #7279: Comparisons involving a Decimal signaling NaN now
729 signal InvalidOperation instead of returning False. (Comparisons
730 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
731 are now hashable; Decimal signaling NaNs remain unhashable.
732
733- Issue #2531: Comparison operations between floats and Decimal
734 instances now return a result based on the numeric values of the
735 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000736 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000737 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000738
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000739- Added a subtract() method to collections.Counter().
740
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000741- Issue #8233: When run as a script, py_compile.py optionally takes a single
742 argument `-` which tells it to read files to compile from stdin. Each line
743 is read on demand and the named file is compiled immediately. (Original
744 patch by Piotr Ożarowski).
745
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000746- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
747 form feed (0x0C) are now considered linebreaks, as specified in Unicode
748 Standard Annex #14. See issue #7643.
749 http://www.unicode.org/reports/tr14/
750
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000751- Comparisons using one of <, <=, >, >= between a complex instance and
752 a Fractions instance now raise TypeError instead of returning
753 True/False. This makes Fraction <=> complex comparisons consistent with
754 int <=> complex, float <=> complex, and complex <=> complex comparisons.
755
Antoine Pitrou39b35432010-03-23 00:25:54 +0000756- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
757 some methods (such as oss_mixer_device.fileno()) were not available.
758 Initial patch by Bertrand Janin.
759
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000760- Issue #8205: Remove the "Modules" directory from sys.path when Python is
761 running from the build directory (POSIX only).
762
Antoine Pitrou910bd512010-03-22 20:11:09 +0000763- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
764 didn't support chflags() (for example ZFS under FreeBSD). The error is
765 now silenced.
766
R. David Murrayca2edce2010-03-22 17:48:48 +0000767- Issue #7860: platform.uname now reports the correct 'machine' type
768 when Python is running in WOW64 mode on 64 bit Windows.
769
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000770- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
771 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
772 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000773
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000774- Issue #4282: Fix the main function of the profile module for a non-ASCII
775 script, open the file in binary mode and not in text mode with the default
776 (utf8) encoding.
777
Florent Xicluna54467e02010-03-21 12:29:50 +0000778- Issue #8179: Fix macpath.realpath() on a non-existing path.
779
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000780- Issue #8024: Update the Unicode database to 5.2.
781
Benjamin Peterson00888932010-03-18 22:37:38 +0000782- Issue #8168: py_compile now handles files with utf-8 BOMS.
783
Benjamin Peterson689a5582010-03-18 22:29:52 +0000784- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
785 detected.
786
Martin v. Löwis4b003072010-03-16 13:19:21 +0000787- Issue #6716/2: Backslash-replace error output in compilall.
788
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000789- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
790 with Tcl/Tk-8.5.
791
Matthias Klosec33b9022010-03-16 00:36:26 +0000792- Issue #8140: extend compileall to compile single files. Add -i option.
793
Matthias Klose82f60912010-03-15 13:46:04 +0000794- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
795 the locale.
796
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000797- The internals of the subprocess module on POSIX systems have been replaced
798 by an extension module (_posixsubprocess) so that the fork()+exec() can be
799 done safely without the possibility of deadlock in multithreaded applications.
800
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000801- subprocess.Popen now has restore_signals and start_new_session features.
802 The default of restore_signals=True is a new behavior compared to earlier
803 Python versions. This means that signals such as SIGPIPE are not ignored
804 by default in subprocesses launched by Python (Issue #1652).
805
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000806- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
807 cElementTree module is updated too.
808
Victor Stinnerb33062c2010-03-12 14:27:16 +0000809- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to
810 an non existent program name and Python is unable to retrieve the real
811 program name
812

814
Ezio Melottib92ed7c2010-03-06 15:24:08 +0000815- Issue #6509: fix re.sub to work properly when the pattern, the string, and
816 the replacement were all bytes. Patch by Antoine Pitrou.
817
Gerhard Häringf9cee222010-03-05 15:20:03 +0000818- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
819 bugs and allows loading SQLite extensions from shared libraries.
820
Ezio Melottida227042010-03-14 11:51:00 +0000821- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public

Victor Stinnercee3ae82010-03-04 00:29:24 +0000824- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
825 reset also the pointer to the current pointer context.
826
Lars Gustäbel01385812010-03-03 12:08:54 +0000827- Issue #7232: Add support for the context manager protocol to the TarFile

834
Florent Xiclunac279ebf2010-02-27 11:31:21 +0000835- Issue #691291: codecs.open() should not convert end of lines on reading and
836 writing.
837
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000838- Issue #7869: logging: improved diagnostic for format-time errors.

Thomas Heller5117b0b2010-02-23 20:25:02 +0000846- Issue #7959: ctypes callback functions are now registered correctly
Ezio Melotti8b1458b2010-02-24 16:55:43 +0000847 with the cycle garbage collector.
Thomas Heller5117b0b2010-02-23 20:25:02 +0000848
Tarek Ziadé8e615ae2010-02-23 06:00:04 +0000849- Issue #5801: removed spurious empty lines in wsgiref.
850
Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +0000851- Issue #6666: fix bug in trace.py that applied the list of directories
852 to be ignored only to the first file. Noted by Bogdan Opanchuk.
853
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000854- Issue #7597: curses.use_env() can now be called before initscr().
855 Noted by Kan-Ru Chen.
856
Ezio Melotti19e4acf2010-02-22 15:59:01 +0000857- Issue #7310: fix the __repr__ of os.environ to show the environment variables.

860 messages parsed by email.Parser.HeaderParser.
861
Brett Cannonef7d6722010-02-19 16:04:36 +0000862- Issue #7361: Importlib was not properly checking the number of bytes in
863 bytecode file when it was less then 8 bytes.
864
Mark Dickinson84230a12010-02-18 14:49:50 +0000865- Issue #7633: In the decimal module, Context class methods (with the
866 exception of canonical and is_canonical) now accept instances of int
867 and long wherever a Decimal instance is accepted, and implicitly
868 convert that argument to Decimal. Previously only some arguments
869 were converted.
870
R. David Murray1f449142010-02-11 00:15:05 +0000871- Issue #7835: shelve should no longer produce mysterious warnings during
872 interpreter shutdown.
873
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000874- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
875 in XML processing instructions and comments. These raw characters are
876 allowed by the XML specification, and are necessary when outputting e.g.
877 PHP code in a processing instruction. Patch by Neil Muller.
878
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000879- Issue #6233: ElementTree failed converting unicode characters to XML

884 specify the compression type.
885
Antoine Pitroub6375f12010-02-04 20:23:24 +0000886- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
887 specified, rather than fall through to AF_PACKET (in the `socket` module).
888 Also, raise ValueError rather than TypeError when an unknown TIPC address
889 type is specified. Patch by Brian Curtin.
890
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000891- Issue #6939: Fix file I/O objects in the `io` module to keep the original
892 file position when calling `truncate()`. It would previously change the
893 file position to the given argument, which goes against the tradition of
894 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
895
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000896- Issue #7610: Reworked implementation of the internal
897 :class:`zipfile.ZipExtFile` class used to represent files stored inside
898 an archive. The new implementation is significantly faster and can
899 be wrapped in a :class:`io.BufferedReader` object for more speedups.
900 It also solves an issue where interleaved calls to `read()` and
901 `readline()` give wrong results. Patch by Nir Aides.
902
Jesse Noller1f0b6582010-01-27 03:36:01 +0000903- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
904 allowing for a maximum number of tasks within the pool to be completed by
905 the worker before that worker is terminated, and a new one created to
906 replace it.
907

1581 leak-chasing test runs give sensible results. The previous method of
1582 reaping threads could return successfully while some Thread objects were
1583 still referenced. This also introduces a new private function:
1584 :func:`_thread._count()`.
1585
R. David Murray27144602009-10-19 15:26:16 +00001586- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1587 longer runs the risk of causing the worker thread to fail.
1588
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001589- Issue #7055: test___all__ now greedily detects all modules which have an

1594 and a new section in the summary report at the end.

1597
Brett Cannon3c273842009-07-20 00:14:29 +00001598- Fixed tests in importlib.test.source.test_abc_loader that were masking
1599 the proper exceptions that should be raised for missing or improper code
1600 object bytecode.
1601
Brett Cannonb49c70c2009-07-15 04:08:33 +00001602- Removed importlib's custom test discovery code and switched to

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001757- Issue #5829: complex("1e500") no longer raises OverflowError. This
1758 makes it consistent with float("1e500") and interpretation of real
1759 and imaginary literals.

1766 (1) inf and nan strings with trailing whitespace were incorrectly
1767 rejected; (2) parsing of strings representing infinities and nans
1768 was locale aware; and (3) the interpretation of fromhex('-nan')
1769 didn't match that of float('-nan').

1872Core and Builtins
1873-----------------
1874
Mark Dickinson865e01a2009-05-07 16:37:01 +00001875- Issue #5914: Add new C API function PyOS_string_to_double, and
1876 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1877
Eric Smith741191f2009-05-06 13:08:15 +00001878- Issue #3382: float.__format__, complex.__format__, and %-formatting
1879 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1880 affects nan -> NAN and inf -> INF.
1881
Mark Hammond5a607a32009-05-06 08:04:54 +00001882- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1883 in all operations, including splitdrive, split, etc. splitunc() now issues
1884 a PendingDeprecation warning.
1885
Eric Smith63376222009-05-05 14:04:18 +00001886- Issue #5920: For float.__format__, change the behavior with the
1887 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1888 to be like 'g' but with at least one decimal point and with a
1889 default precision of 12. Previously, the behavior the same but with
1890 a default precision of 6. This more closely matches str(), and
1891 reduces surprises when adding alignment flags to the empty
1892 presentation type. This also affects the new complex.__format__ in
1893 the same way.
1894
Martin v. Löwis011e8422009-05-05 04:43:17 +00001895- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1896
R. David Murrayb18500d2009-05-04 22:59:07 +00001897- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1898 shadowed by classtype's, even if it was None. property now
1899 inserts the __doc__ into the subclass instance __dict__.
1900
Antoine Pitrou244651a2009-05-04 18:56:13 +00001901- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1902 sequences. Patch by Nick Barnes and Victor Stinner.
1903
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001904- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001905
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001906- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1907 received a new method, detach(). detach() disconnects the underlying stream
1908 from the buffer or text IO and returns it.
1909
Mark Dickinson33841c32009-05-01 15:37:04 +00001910- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1911 floats with absolute value over 1e50. Also remove length
1912 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1913 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001914
Eric Smith741191f2009-05-06 13:08:15 +00001915- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001916 format(complex(1, 2./3), '.5') now produces a sensible result.
1917
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001918- Issue #5864: Fix empty format code formatting for floats so that it
1919 never gives more than the requested number of significant digits.
1920
Eric Smith6dc46f52009-04-27 20:39:49 +00001921- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1922 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1923
Eric Smithcc32a112009-04-26 21:35:14 +00001924- Issue #5835: Deprecate PyOS_ascii_formatd.
1925
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001926- Issue #4971: Fix titlecase for characters that are their own
1927 titlecase, but not their own uppercase.
1928
Benjamin Peterson193152c2009-04-25 01:08:45 +00001929- Issue #5283: Setting __class__ in __del__ caused a segfault.
1930
Mark Dickinsonad476da2009-04-23 19:14:16 +00001931- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1932 z involves nans, infs or negative zeros.
1933
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001934- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001935
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001936- Issue #1869 (and many duplicates): make round(x, n) correctly
1937 rounded for a float x, by using the decimal <-> binary conversions
1938 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1939 consistently agrees with format(x, '.2f').
1940
Benjamin Petersonae937c02009-04-18 20:54:08 +00001941- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1942 some builtin types.
1943
Eric Smith0923d1d2009-04-16 20:16:10 +00001944- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1945
Eric Smith35e84722009-04-16 20:21:28 +00001946- Issue #5515: str.format() type 'n' combined with commas and leading
1947 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001948
1949- Implement PEP 378, Format Specifier for Thousands Separator, for
1950 floats.
1951
Mark Dickinson3370cce2009-04-17 22:40:53 +00001952- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001953 1e11, not 1e12. This avoids printing 13 significant digits in
1954 situations where only 12 of them are correct. Example problem
1955 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1956 long time.)
1957
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001958- Issue #1580: On most platforms, use a 'short' float repr: for a
1959 finite float x, repr(x) now outputs a string based on the shortest
1960 sequence of decimal digits that rounds to x. Previous behaviour was
1961 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001962 Another minor difference is that the new repr switches to
1963 exponential notation at 1e16 instead of the previous 1e17; this
1964 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001965
1966 There's a new sys attribute sys.float_repr_style, which takes
1967 the value 'short' to indicate that we're using short float repr,
1968 and 'legacy' if the short float repr isn't available for one
1969 reason or another.
1970
1971 The float repr change involves incorporating David Gay's 'perfect
1972 rounding' code into the Python core (it's in Python/dtoa.c). As a
1973 secondary consequence, all string-to-float and float-to-string
1974 conversions (including all float formatting operations) will be
1975 correctly rounded on these platforms.
1976
1977 See issue 1580 discussions for details of platforms for which
1978 this change does not apply.
1979
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001980- Issue #5759: float() didn't call __float__ on str subclasses.
1981
Georg Brandlabc38772009-04-12 15:51:51 +00001982- The string.maketrans() function is deprecated; there is a new static method
1983 maketrans() on the bytes and bytearray classes. This removes confusion about
1984 the types string.maketrans() is supposed to work with, and mirrors the
1985 methods available on the str class.
1986
R. David Murraydc6da8a2009-04-09 22:16:43 +00001987- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1988 its clarity and its speed.
1989
Matthias Klose091c7b12009-04-07 13:24:27 +00001990- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1991 to avoid compiler warnings.
1992
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001993- Issue #3739: The unicode-internal encoder now reports the number of characters
1994 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrou05608432009-01-09 18:53:14 +00002343- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2344 flag to work properly. Furthermore, when specifying -u, the text stdout
2345 and stderr streams have line-by-line buffering enabled (the default being
2346 to buffer arbitrary chunks of data).
2347
Raymond Hettinger35631532009-01-09 03:58:09 +00002348- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2349 instead of ints (reducing its size from 4 to 8 times thereby reducing
2350 Python's overall memory).
2351
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002352- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2353 an existing .py counterpart, override the co_filename attributes of all
2354 code objects if the original filename is obsolete (which can happen if the
2355 file has been renamed, moved, or if it is accessed through different paths).
2356 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2357
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002358- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2359 one byte. Also fixes the meaning of len() so that it returns the number of
2360 items, rather than the size in bytes.
2361

2375
Georg Brandlccc47b62008-12-28 11:44:14 +00002376- Issue #4759: None is now allowed as the first argument of

2378
Skip Montanaro80072cb2008-12-23 03:51:14 +00002379- Added test case to ensure attempts to read from a file opened for writing
2380 fail.

2395 failures on OS X.
2396
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002397- Issue #4597: Fixed several opcodes that weren't always propagating

2402
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002403- Issue #4445: Replace "sizeof(PyBytesObject)" with
2404 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2405 bytes instances. On a typical machine this saves 3 bytes of memory
2406 (on average) per allocation of a bytes instance.
2407
Christian Heimesa872de52008-12-05 08:26:55 +00002408- Issue #4533: File read operation was dreadfully slow due to a slowly
2409 growing read buffer. Fixed by using the same growth rate algorithm as
2410 Python 2.x.
2411
Antoine Pitrou5504e892008-12-06 21:27:53 +00002412- Issue #4509: Various issues surrounding resize of bytearray objects to

2414
Georg Brandlf9734072008-12-07 15:30:06 +00002415- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2416 method on file objects with closefd=False. The file descriptor is still
2417 kept open but the file object behaves like a closed file. The ``FileIO``
2418 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00002427- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2428 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2429 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2430 of using the replace error handler in PyUnicode_DecodeUTF8().

2751 do an explicit seek to the end of file (so that e.g. tell() returns the
