Benjamin Peterson46ea4f72009-06-27 21:40:27 +00007What's New in Python 3.2 Alpha 1?
8=================================

10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000015- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
16 the interpreter with characters outside the Basic Multilingual Plane
17 (higher than 0x10000).
18
Mark Dickinsonc7301312010-06-10 16:05:10 +000019- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
20 raise TypeError instead of giving a DeprecationWarning when a float
21 is parsed using the 'L' code (for long long). (All other integer
22 codes already raise TypeError in this case.)
23
Victor Stinner600d3be2010-06-10 12:00:55 +000024- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
25 enable shortcuts for upper case encoding name. Add also a shortcut for
26 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
27
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000028- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
29 doesn't support "char buffer" anymore in Python3.
30
31- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
32 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
33 like bytearray.
34
Victor Stinner33109a12010-05-28 21:55:10 +000035- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
36 used anymore and it was never documented.
37
Benjamin Peterson95304522010-06-08 14:57:22 +000038- In the str.format(), raise a ValueError when indexes to arguments are too
39 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000040
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000041- Issue #2844: Make int('42', n) consistently raise ValueError for
42 invalid integers n (including n = -909).
43
Mark Dickinsondc787d22010-05-23 13:33:13 +000044- Issue #8188: Introduce a new scheme for computing hashes of numbers
45 (instances of int, float, complex, decimal.Decimal and
46 fractions.Fraction) that makes it easy to maintain the invariant
47 that hash(x) == hash(y) whenever x and y have equal value.
48
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000049- Issue #8748: Fix two issues with comparisons between complex and integer
50 objects. (1) The comparison could incorrectly return True in some cases
51 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
52 (2) The comparison raised an OverflowError for large integers, leading
53 to unpredictable exceptions when combining integers and complex objects
54 in sets or dicts.
55
Victor Stinner7d79b8b2010-05-19 20:40:50 +000056- Issue #8766: Initialize _warnings module before importing the first module.
57 Fix a crash if an empty directory called "encodings" exists in sys.path.
58
Victor Stinner9ca9c252010-05-19 16:53:30 +000059- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
60 encoding and surrogateespace error handler instead of the locale encoding to
61 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
62
Victor Stinner372ac5e2010-05-17 01:26:01 +000063- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
64 (instead of strict) error handler to escape surrogates
65
Victor Stinnerae6265f2010-05-15 16:27:27 +000066- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
67 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000068 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
69 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +000070
Victor Stinner59e62db2010-05-15 13:14:32 +000071- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
72 error handler, not only the default error handler (strict)
73
Victor Stinnerb744ba12010-05-15 12:27:16 +000074- Issue #8610: Load file system codec at startup, and display a fatal error on
75 failure. Set the file system encoding to utf-8 (instead of None) if getting
76 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
77
Victor Stinner0964ee12010-04-30 16:48:45 +000078- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
79 PyUnicode_FromString() to support surrogates in the filename and use the
80 right encoding
81
Georg Brandl8569e582010-05-19 20:57:08 +000082- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
83
Victor Stinnerb9a20ad2010-04-30 16:37:52 +000084- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
85
Benjamin Petersonfb886362010-04-24 18:21:17 +000086- Issue #8419: Prevent the dict constructor from accepting non-string keyword
87 arguments.
88
Victor Stinner14284c22010-04-23 12:02:30 +000089- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
90 indirectly Python signal handlers anymore because mywrite() ignores
91 exceptions (KeyboardInterrupt)
92
Victor Stinner31be90b2010-04-22 19:38:16 +000093- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
94 unicode string (eg. backslashreplace)
95
Victor Stinnerdcb24032010-04-22 12:08:36 +000096- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
97 you have to convert your bytearray filenames to bytes
98
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +000099- Issue #7332: Remove the 16KB stack-based buffer in
100 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
101 benefit compared to the dynamic memory allocation fallback. Patch by
102 Charles-François Natali.
103
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000104- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
105 passed to bytes or bytearray.
106
Philip Jenvey0805ca32010-04-07 04:04:10 +0000107- Issue #7301: Add environment variable $PYTHONWARNINGS.
108
Benjamin Petersond856ab62010-04-06 21:55:16 +0000109- Issue #8329: Don't return the same lists from select.select when no fds are
110 changed.
111
Mark Dickinson3318d292010-04-06 16:53:17 +0000112- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
113 on 64-bit machines. The shift count for either left or right shift is
114 permitted to be up to sys.maxsize.
115
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000116- Ensure that tokenization of identifiers is not affected by locale.

121
Marc-André Lemburg177ab082010-05-05 13:32:59 +0000122- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in
123 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000124
Victor Stinner120c2122010-03-25 00:30:28 +0000125- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
126 is unknown
127
Victor Stinner808fc0a2010-03-22 12:50:40 +0000128- Issue #1583863: An str subclass can now override the __str__ method
129
Mark Dickinsond59b4162010-03-13 11:34:40 +0000130- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
131 PyMemberDefs could produce an internal error; raise TypeError instead.
132
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000133- Issue #7845: Rich comparison methods on the complex type now return
134 NotImplemented rather than raising a TypeError when comparing with an
135 incompatible type; this allows user-defined classes to implement their own
136 comparisons with complex.
137
Victor Stinner52f6dd72010-03-12 14:45:56 +0000138- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
139 (SIGINT). If an error occurs while importing the site module, the error is
140 printed and Python exits. Initialize the GIL before importing the site
141 module.
142
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000143- Issue #7173: Generator finalization could invalidate sys.exc_info().

167 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
168 and PyOS_string_to_double instead. See issue #5835 for the original
169 deprecations.
170
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000171- Issue #7385: Fix a crash in `MemoryView_FromObject` when
172 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
173
Mark Dickinsonbc099642010-01-29 17:27:24 +0000174- Issue #7788: Fix an interpreter crash produced by deleting a list
175 slice with very large step value.
176
Eric Smithf7bb5782010-01-27 00:44:57 +0000177- Issue #7766: Change sys.getwindowsversion() return value to a named
178 tuple and add the additional members returned in an OSVERSIONINFOEX
179 structure. The new members are service_pack_major, service_pack_minor,
180 suite_mask, and product_type.
181
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000182- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
183 could crash in many places because of the PyByteArray_AS_STRING() macro
184 returning NULL. The macro now returns a statically allocated empty
185 string instead.
186
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000187- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
188 where the right hand operand is a set of constants, by turning the set into
189 a frozenset and pre-building it as a constant. The comparison operation
190 is made against the constant instead of building a new set each time it is
191 executed (a similar optimization already existed which turned a list of
192 constants into a pre-built tuple). Patch and additional tests by Dave
193 Malcolm.
194
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000195- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
196 methods of bytes, bytearray and unicode objects by using a common
197 implementation based on stringlib's fast search. Patch by Florent Xicluna.

200 alpha 2, including: (1) a serious 'wrong output' bug that could
201 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
202 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000203 strings corresponding to subnormal values, (3) a memory leak for
204 some values large enough to cause overflow, and (4) a number of
205 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000206
Benjamin Petersonaea44282010-01-04 01:10:28 +0000207- The __complex__ method is now looked up on the class of instances to make it

215
Mark Dickinson9ab44b52009-12-30 16:22:49 +0000216- Issue #7534: Fix handling of IEEE specials (infinities, nans,
217 negative zero) in ** operator. The behaviour now conforms to that
218 described in C99 Annex F.
219
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000220- Issue #1811: improve accuracy and cross-platform consistency for
221 true division of integers: the result of a/b is now correctly
222 rounded for ints a and b (at least on IEEE 754 platforms), and in
223 particular does not depend on the internal representation of an int.
224
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000225- Issue #6834: replace the implementation for the 'python' and 'pythonw'
226 executables on OSX.
227
228 These executables now work properly with the arch(1) command:
229 ``arch -ppc python`` will start a universal binary version of python
230 in PPC mode (unlike previous releases).
231
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000232- Issue #7466: segmentation fault when the garbage collector is called

240
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000241- Issue #7085: Fix crash when importing some extensions in a thread
242 on MacOSX 10.6.
243

247 implement the relevant rich comparison methods.
248
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000249- Issue #7298: fixes for range and reversed(range(...)). Iteration
250 over range(a, b, c) incorrectly gave an empty iterator when a, b and
251 c fit in C long but the length of the range did not. Also fix
252 several cases where reversed(range(a, b, c)) gave wrong results, and
253 fix a refleak for reversed(range(a, b, c)) with large arguments.
254
Raymond Hettingerfc438512009-11-01 20:55:33 +0000255- Issue #7244: itertools.izip_longest() no longer ignores exceptions

381 has '\0' at the end.
382
Mark Dickinsonde604012010-01-01 19:27:32 +0000383- Issue #5080: The argument parsing functions PyArg_ParseTuple,
384 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
385 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
386 DeprecationWarning for float arguments passed with the 'L' format
387 code. This will become a TypeError in a future version of Python,
388 to match the behaviour of the other integer format codes.

Mark Dickinson08ade6f2010-06-11 10:44:52 +0000428 now permitted, returning a result based on the exact numerical
429 values of the operands. This builds on issue #2531, which allowed
430 Decimal-to-float comparisons; all comparisons involving numeric
431 types (bool, int, float, complex, Decimal, Fraction) should now
432 act as expected.

Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000612- Issue #5103: SSL handshake would ignore the socket timeout and block
613 indefinitely if the other end didn't respond.
614
615- The do_handshake() method of SSL objects now adjusts the blocking mode of
616 the SSL structure if necessary (as other methods already do).
617
Victor Stinner13bb71c2010-04-23 21:41:56 +0000618- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
619 and bytes strings for environment keys and values
620
Victor Stinner4d078042010-04-23 19:28:32 +0000621- Issue #8467: Pure Python implementation of subprocess encodes the error

626
Sean Reifscheider13daf122010-04-23 09:29:52 +0000627- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
628 the string "python" as the *ident*. openlog() arguments are all optional
629 and keywords.
630
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000631- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
632 a non-infinite timeout. Also make that method friendlier with applications
633 wanting to continue using the socket in clear-text mode, by disabling
634 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
635
Antoine Pitrou7062db82010-04-22 13:30:10 +0000636- Issue #8496: make mailcap.lookup() always return a list, rather than an
637 iterator. Patch by Gregory Nofi.
638
Victor Stinner35466c52010-04-22 11:23:23 +0000639- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
640 collation name contains a surrogate character.
641
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000642- Issue #8484: Load all ciphers and digest algorithms when initializing
643 the _ssl extension, such that verification of some SSL certificates
644 doesn't fail because of an "unknown algorithm".
645
Tarek Ziadéfb437512010-04-20 08:57:33 +0000646- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
647
Victor Stinnere125f132010-05-15 21:04:43 +0000648- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000649 shutil.copytree.
650
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000651- Issue #4814: timeout parameter is now applied also for connections resulting
652 from PORT/EPRT commands.
653
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000654- Issue #8463: added missing reference to bztar in shutil's documentation.
655
Ronald Oussoren84151202010-04-18 20:46:11 +0000656- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
657 (as long as the user didn't specify 'automatic proxy configuration').
658
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000659- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
660 code as stated in RFC-959 at chapter 5.4.
661
Victor Stinner738446f02010-04-18 00:00:44 +0000662- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
663 surrogates.
664
Antoine Pitrou0454af92010-04-17 23:51:58 +0000665- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000666 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000667
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000668- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
669 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
670
Victor Stinner0e59cc32010-04-16 23:49:32 +0000671- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
672 the current working directory.

681 Locke and Hans Ulrich Niedermann.
682
R. David Murrayd48739f2010-04-14 18:59:18 +0000683- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
684
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000685- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
686 module now takes an optional timeout argument in seconds. Timeout support
687 relies on the system threading library, so as to avoid a semi-busy wait
688 loop.
689
Victor Stinner485fb562010-04-13 11:07:24 +0000690- Issue #8383: pickle and pickletools use surrogatepass error handler when
691 encoding unicode as utf8 to support lone surrogates and stay compatible with
692 Python 2.x and 3.0
693
R. David Murrayb2416e52010-04-12 16:58:02 +0000694- Issue #7585: difflib context and unified diffs now place a tab between
695 filename and date, conforming to the 'standards' they were originally
696 designed to follow. This improves compatibility with patch tools.
697
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000698- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
699 character sets will now consistently use a Content-Transfer-Encoding of
700 7bit rather than sometimes being marked as 8bit.
701
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000702- Issue #8375: test_distutils now checks if the temporary directory are still
703 present before it cleans them.
704
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000705- Issue #8374: Update the internal alias table in the :mod:`locale` module
706 to cover recent locale changes and additions.
707
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000708- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
709 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
710 and `ssl.OPENSSL_VERSION_NUMBER`.
711
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000712- Add functools.total_ordering() and functools.cmp_to_key().
713
Mark Dickinson089b00c2010-04-03 15:51:03 +0000714- Issue #8257: The Decimal construct now accepts a float instance
715 directly, converting that float to a Decimal of equal value:
716
717 >>> Decimal(1.1)
718 Decimal('1.100000000000000088817841970012523233890533447265625')
719
Mark Dickinson98127c32010-04-03 11:18:52 +0000720- Issue #8294: The Fraction constructor now accepts Decimal and float
721 instances directly.
722
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000723- Issue #7279: Comparisons involving a Decimal signaling NaN now
724 signal InvalidOperation instead of returning False. (Comparisons
725 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
726 are now hashable; Decimal signaling NaNs remain unhashable.
727
728- Issue #2531: Comparison operations between floats and Decimal
729 instances now return a result based on the numeric values of the
730 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000731 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000732 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000733
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000734- Added a subtract() method to collections.Counter().
735
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000736- Issue #8233: When run as a script, py_compile.py optionally takes a single
737 argument `-` which tells it to read files to compile from stdin. Each line
738 is read on demand and the named file is compiled immediately. (Original
739 patch by Piotr Ożarowski).
740
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000741- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
742 form feed (0x0C) are now considered linebreaks, as specified in Unicode
743 Standard Annex #14. See issue #7643.
744 http://www.unicode.org/reports/tr14/
745
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000746- Comparisons using one of <, <=, >, >= between a complex instance and
747 a Fractions instance now raise TypeError instead of returning
748 True/False. This makes Fraction <=> complex comparisons consistent with
749 int <=> complex, float <=> complex, and complex <=> complex comparisons.
750
Antoine Pitrou39b35432010-03-23 00:25:54 +0000751- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

753 Initial patch by Bertrand Janin.
754
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000755- Issue #8205: Remove the "Modules" directory from sys.path when Python is
756 running from the build directory (POSIX only).
757
Antoine Pitrou910bd512010-03-22 20:11:09 +0000758- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
759 didn't support chflags() (for example ZFS under FreeBSD). The error is
760 now silenced.
761
R. David Murrayca2edce2010-03-22 17:48:48 +0000762- Issue #7860: platform.uname now reports the correct 'machine' type
763 when Python is running in WOW64 mode on 64 bit Windows.
764
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000765- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
766 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
767 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000768
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000769- Issue #4282: Fix the main function of the profile module for a non-ASCII
770 script, open the file in binary mode and not in text mode with the default
771 (utf8) encoding.
772
Florent Xicluna54467e02010-03-21 12:29:50 +0000773- Issue #8179: Fix macpath.realpath() on a non-existing path.

776
Benjamin Peterson00888932010-03-18 22:37:38 +0000777- Issue #8168: py_compile now handles files with utf-8 BOMS.
778
Benjamin Peterson689a5582010-03-18 22:29:52 +0000779- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
780 detected.
781
Martin v. Löwis4b003072010-03-16 13:19:21 +0000782- Issue #6716/2: Backslash-replace error output in compilall.

Matthias Klosea6d9abf2010-03-16 10:51:28 +0000784- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
785 with Tcl/Tk-8.5.
786
Matthias Klosec33b9022010-03-16 00:36:26 +0000787- Issue #8140: extend compileall to compile single files. Add -i option.

Matthias Klose82f60912010-03-15 13:46:04 +0000789- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
790 the locale.
791
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000792- The internals of the subprocess module on POSIX systems have been replaced
793 by an extension module (_posixsubprocess) so that the fork()+exec() can be
794 done safely without the possibility of deadlock in multithreaded applications.
795
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000796- subprocess.Popen now has restore_signals and start_new_session features.
797 The default of restore_signals=True is a new behavior compared to earlier
798 Python versions. This means that signals such as SIGPIPE are not ignored
799 by default in subprocesses launched by Python (Issue #1652).
800
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000801- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

811 the replacement were all bytes. Patch by Antoine Pitrou.
812
Gerhard Häringf9cee222010-03-05 15:20:03 +0000813- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
814 bugs and allows loading SQLite extensions from shared libraries.
815

845
Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +0000846- Issue #6666: fix bug in trace.py that applied the list of directories
847 to be ignored only to the first file. Noted by Bogdan Opanchuk.
848
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000849- Issue #7597: curses.use_env() can now be called before initscr().

859
Mark Dickinson84230a12010-02-18 14:49:50 +0000860- Issue #7633: In the decimal module, Context class methods (with the
861 exception of canonical and is_canonical) now accept instances of int
862 and long wherever a Decimal instance is accepted, and implicitly
863 convert that argument to Decimal. Previously only some arguments
864 were converted.
865
R. David Murray1f449142010-02-11 00:15:05 +0000866- Issue #7835: shelve should no longer produce mysterious warnings during

868
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000869- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
870 in XML processing instructions and comments. These raw characters are
871 allowed by the XML specification, and are necessary when outputting e.g.
872 PHP code in a processing instruction. Patch by Neil Muller.

883 Also, raise ValueError rather than TypeError when an unknown TIPC address
884 type is specified. Patch by Brian Curtin.
885
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000886- Issue #6939: Fix file I/O objects in the `io` module to keep the original
887 file position when calling `truncate()`. It would previously change the
888 file position to the given argument, which goes against the tradition of
889 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
890
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000891- Issue #7610: Reworked implementation of the internal
892 :class:`zipfile.ZipExtFile` class used to represent files stored inside
893 an archive. The new implementation is significantly faster and can
894 be wrapped in a :class:`io.BufferedReader` object for more speedups.
895 It also solves an issue where interleaved calls to `read()` and
896 `readline()` give wrong results. Patch by Nir Aides.
897
Jesse Noller1f0b6582010-01-27 03:36:01 +0000898- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

900 the worker before that worker is terminated, and a new one created to
901 replace it.
902
Benjamin Petersond6326642010-01-27 02:25:58 +0000903- Issue #7792: Registering non-classes to ABCs raised an obscure error.

1573 calling methods on the object.
1574
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001575- Issue #7222: Make thread "reaping" more reliable so that reference
1576 leak-chasing test runs give sensible results. The previous method of
1577 reaping threads could return successfully while some Thread objects were
1578 still referenced. This also introduces a new private function:
1579 :func:`_thread._count()`.
1580
R. David Murray27144602009-10-19 15:26:16 +00001581- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1582 longer runs the risk of causing the worker thread to fail.
1583
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001584- Issue #7055: test___all__ now greedily detects all modules which have an

1589 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001590
Mark Dickinson2e304402009-10-04 18:43:54 +00001591- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1592
Brett Cannon3c273842009-07-20 00:14:29 +00001593- Fixed tests in importlib.test.source.test_abc_loader that were masking
1594 the proper exceptions that should be raised for missing or improper code
1595 object bytecode.
1596
Brett Cannonb49c70c2009-07-15 04:08:33 +00001597- Removed importlib's custom test discovery code and switched to

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001760- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1761 (1) inf and nan strings with trailing whitespace were incorrectly
1762 rejected; (2) parsing of strings representing infinities and nans
1763 was locale aware; and (3) the interpretation of fromhex('-nan')
1764 didn't match that of float('-nan').

1867Core and Builtins
1868-----------------
1869
Mark Dickinson865e01a2009-05-07 16:37:01 +00001870- Issue #5914: Add new C API function PyOS_string_to_double, and
1871 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1872
Eric Smith741191f2009-05-06 13:08:15 +00001873- Issue #3382: float.__format__, complex.__format__, and %-formatting
1874 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1875 affects nan -> NAN and inf -> INF.
1876
Mark Hammond5a607a32009-05-06 08:04:54 +00001877- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1878 in all operations, including splitdrive, split, etc. splitunc() now issues
1879 a PendingDeprecation warning.
1880
Eric Smith63376222009-05-05 14:04:18 +00001881- Issue #5920: For float.__format__, change the behavior with the
1882 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1883 to be like 'g' but with at least one decimal point and with a
1884 default precision of 12. Previously, the behavior the same but with
1885 a default precision of 6. This more closely matches str(), and
1886 reduces surprises when adding alignment flags to the empty
1887 presentation type. This also affects the new complex.__format__ in
1888 the same way.
1889
Martin v. Löwis011e8422009-05-05 04:43:17 +00001890- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1891
R. David Murrayb18500d2009-05-04 22:59:07 +00001892- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1893 shadowed by classtype's, even if it was None. property now
1894 inserts the __doc__ into the subclass instance __dict__.
1895
Antoine Pitrou244651a2009-05-04 18:56:13 +00001896- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1897 sequences. Patch by Nick Barnes and Victor Stinner.
1898
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001899- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001900
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001901- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1902 received a new method, detach(). detach() disconnects the underlying stream
1903 from the buffer or text IO and returns it.
1904
Mark Dickinson33841c32009-05-01 15:37:04 +00001905- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1906 floats with absolute value over 1e50. Also remove length
1907 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1908 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001909
Eric Smith741191f2009-05-06 13:08:15 +00001910- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001911 format(complex(1, 2./3), '.5') now produces a sensible result.
1912
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001913- Issue #5864: Fix empty format code formatting for floats so that it
1914 never gives more than the requested number of significant digits.
1915
Eric Smith6dc46f52009-04-27 20:39:49 +00001916- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1917 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1918
Eric Smithcc32a112009-04-26 21:35:14 +00001919- Issue #5835: Deprecate PyOS_ascii_formatd.
1920
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001921- Issue #4971: Fix titlecase for characters that are their own
1922 titlecase, but not their own uppercase.
1923
Benjamin Peterson193152c2009-04-25 01:08:45 +00001924- Issue #5283: Setting __class__ in __del__ caused a segfault.
1925
Mark Dickinsonad476da2009-04-23 19:14:16 +00001926- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1927 z involves nans, infs or negative zeros.
1928
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001929- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001930
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001931- Issue #1869 (and many duplicates): make round(x, n) correctly
1932 rounded for a float x, by using the decimal <-> binary conversions
1933 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1934 consistently agrees with format(x, '.2f').
1935
Benjamin Petersonae937c02009-04-18 20:54:08 +00001936- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1937 some builtin types.
1938
Eric Smith0923d1d2009-04-16 20:16:10 +00001939- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1940
Eric Smith35e84722009-04-16 20:21:28 +00001941- Issue #5515: str.format() type 'n' combined with commas and leading
1942 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001943
1944- Implement PEP 378, Format Specifier for Thousands Separator, for
1945 floats.
1946
Mark Dickinson3370cce2009-04-17 22:40:53 +00001947- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001948 1e11, not 1e12. This avoids printing 13 significant digits in
1949 situations where only 12 of them are correct. Example problem
1950 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1951 long time.)
1952
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001953- Issue #1580: On most platforms, use a 'short' float repr: for a
1954 finite float x, repr(x) now outputs a string based on the shortest
1955 sequence of decimal digits that rounds to x. Previous behaviour was
1956 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001957 Another minor difference is that the new repr switches to
1958 exponential notation at 1e16 instead of the previous 1e17; this
1959 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001960
1961 There's a new sys attribute sys.float_repr_style, which takes
1962 the value 'short' to indicate that we're using short float repr,
1963 and 'legacy' if the short float repr isn't available for one
1964 reason or another.
1965
1966 The float repr change involves incorporating David Gay's 'perfect
1967 rounding' code into the Python core (it's in Python/dtoa.c). As a
1968 secondary consequence, all string-to-float and float-to-string
1969 conversions (including all float formatting operations) will be
1970 correctly rounded on these platforms.
1971
1972 See issue 1580 discussions for details of platforms for which
1973 this change does not apply.
1974
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001975- Issue #5759: float() didn't call __float__ on str subclasses.
1976
Georg Brandlabc38772009-04-12 15:51:51 +00001977- The string.maketrans() function is deprecated; there is a new static method
1978 maketrans() on the bytes and bytearray classes. This removes confusion about
1979 the types string.maketrans() is supposed to work with, and mirrors the
1980 methods available on the str class.
1981
R. David Murraydc6da8a2009-04-09 22:16:43 +00001982- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1983 its clarity and its speed.
1984
Matthias Klose091c7b12009-04-07 13:24:27 +00001985- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1986 to avoid compiler warnings.
1987
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001988- Issue #3739: The unicode-internal encoder now reports the number of characters
1989 consumed like any other encoder (instead of the number of bytes).

2068 results in a handle_expt_event call, not handle_read_event, and POLLERR
2069 and POLLNVAL now call handle_close, not handle_expt_event. Also,
2070 dispatcher now has an 'ignore_log_types' attribute for suppressing
2071 log messages, which is set to 'warning' by default.

2147 untrackable objects are not tracked by the garbage collector. This can
2148 reduce the size of collections and therefore the garbage collection overhead
2149 on long-running programs, depending on their particular use of datatypes.

2220 forever on incomplete input. That caused tarfile.open() to hang when used
2221 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2222 partial bzip2 compressed data.

2339 flag to work properly. Furthermore, when specifying -u, the text stdout
2340 and stderr streams have line-by-line buffering enabled (the default being
2341 to buffer arbitrary chunks of data).
2342
Raymond Hettinger35631532009-01-09 03:58:09 +00002343- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

2399 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

2413 object also got a new readonly attribute ``closefd``.

2423 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2424 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2425 of using the replace error handler in PyUnicode_DecodeUTF8().

2746 do an explicit seek to the end of file (so that e.g. tell() returns the
