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 Stinner33109a12010-05-28 21:55:10 +000015- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
16 used anymore and it was never documented.
17
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000018- Issue #2844: Make int('42', n) consistently raise ValueError for
19 invalid integers n (including n = -909).
20
Mark Dickinsondc787d22010-05-23 13:33:13 +000021- Issue #8188: Introduce a new scheme for computing hashes of numbers
22 (instances of int, float, complex, decimal.Decimal and
23 fractions.Fraction) that makes it easy to maintain the invariant
24 that hash(x) == hash(y) whenever x and y have equal value.
25
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000026- Issue #8748: Fix two issues with comparisons between complex and integer
27 objects. (1) The comparison could incorrectly return True in some cases
28 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
29 (2) The comparison raised an OverflowError for large integers, leading
30 to unpredictable exceptions when combining integers and complex objects
31 in sets or dicts.
32
Victor Stinner7d79b8b2010-05-19 20:40:50 +000033- Issue #8766: Initialize _warnings module before importing the first module.
34 Fix a crash if an empty directory called "encodings" exists in sys.path.
35
Victor Stinner9ca9c252010-05-19 16:53:30 +000036- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
37 encoding and surrogateespace error handler instead of the locale encoding to
38 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
39
Victor Stinner372ac5e2010-05-17 01:26:01 +000040- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
41 (instead of strict) error handler to escape surrogates
42
Victor Stinnerae6265f2010-05-15 16:27:27 +000043- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
44 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000045 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
46 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +000047
Victor Stinner59e62db2010-05-15 13:14:32 +000048- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
49 error handler, not only the default error handler (strict)
50
Victor Stinnerb744ba12010-05-15 12:27:16 +000051- Issue #8610: Load file system codec at startup, and display a fatal error on
52 failure. Set the file system encoding to utf-8 (instead of None) if getting
53 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
54
Victor Stinner0964ee12010-04-30 16:48:45 +000055- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
56 PyUnicode_FromString() to support surrogates in the filename and use the
57 right encoding
58
Georg Brandl8569e582010-05-19 20:57:08 +000059- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
60
Victor Stinnerb9a20ad2010-04-30 16:37:52 +000061- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
62
Benjamin Petersonfb886362010-04-24 18:21:17 +000063- Issue #8419: Prevent the dict constructor from accepting non-string keyword
64 arguments.
65
Victor Stinner14284c22010-04-23 12:02:30 +000066- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
67 indirectly Python signal handlers anymore because mywrite() ignores
68 exceptions (KeyboardInterrupt)
69
Victor Stinner31be90b2010-04-22 19:38:16 +000070- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
71 unicode string (eg. backslashreplace)
72
Victor Stinnerdcb24032010-04-22 12:08:36 +000073- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
74 you have to convert your bytearray filenames to bytes
75
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +000076- Issue #7332: Remove the 16KB stack-based buffer in
77 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
78 benefit compared to the dynamic memory allocation fallback. Patch by
79 Charles-François Natali.
80
Benjamin Peterson8380dd52010-04-16 22:51:37 +000081- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
82 passed to bytes or bytearray.
83
Philip Jenvey0805ca32010-04-07 04:04:10 +000084- Issue #7301: Add environment variable $PYTHONWARNINGS.
85
Benjamin Petersond856ab62010-04-06 21:55:16 +000086- Issue #8329: Don't return the same lists from select.select when no fds are
87 changed.
88
Mark Dickinson3318d292010-04-06 16:53:17 +000089- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
90 on 64-bit machines. The shift count for either left or right shift is
91 permitted to be up to sys.maxsize.
92
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000093- Ensure that tokenization of identifiers is not affected by locale.

100 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000101
Victor Stinner120c2122010-03-25 00:30:28 +0000102- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
103 is unknown
104
Victor Stinner808fc0a2010-03-22 12:50:40 +0000105- Issue #1583863: An str subclass can now override the __str__ method
106
Mark Dickinsond59b4162010-03-13 11:34:40 +0000107- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
108 PyMemberDefs could produce an internal error; raise TypeError instead.
109
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000110- Issue #7845: Rich comparison methods on the complex type now return
111 NotImplemented rather than raising a TypeError when comparing with an
112 incompatible type; this allows user-defined classes to implement their own
113 comparisons with complex.
114
Victor Stinner52f6dd72010-03-12 14:45:56 +0000115- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
116 (SIGINT). If an error occurs while importing the site module, the error is
117 printed and Python exits. Initialize the GIL before importing the site
118 module.
119
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000120- Issue #7173: Generator finalization could invalidate sys.exc_info().

129
Larry Hastings1373a072010-02-24 22:49:58 +0000130- Issue #5939: Add additional runtime checking to ensure a valid capsule
131 in Modules/_ctypes/callproc.c.

144 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
145 and PyOS_string_to_double instead. See issue #5835 for the original
146 deprecations.
147
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000148- Issue #7385: Fix a crash in `MemoryView_FromObject` when
149 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
150
Mark Dickinsonbc099642010-01-29 17:27:24 +0000151- Issue #7788: Fix an interpreter crash produced by deleting a list
152 slice with very large step value.
153
Eric Smithf7bb5782010-01-27 00:44:57 +0000154- Issue #7766: Change sys.getwindowsversion() return value to a named
155 tuple and add the additional members returned in an OSVERSIONINFOEX

157 suite_mask, and product_type.
158
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000159- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
160 could crash in many places because of the PyByteArray_AS_STRING() macro
161 returning NULL. The macro now returns a statically allocated empty
162 string instead.
163
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000164- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
165 where the right hand operand is a set of constants, by turning the set into
166 a frozenset and pre-building it as a constant. The comparison operation
167 is made against the constant instead of building a new set each time it is
168 executed (a similar optimization already existed which turned a list of
169 constants into a pre-built tuple). Patch and additional tests by Dave
170 Malcolm.
171
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000172- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
173 methods of bytes, bytearray and unicode objects by using a common
174 implementation based on stringlib's fast search. Patch by Florent Xicluna.
175
Mark Dickinson45b63652010-01-16 18:10:25 +0000176- Issue #7632: Fix various str -> float conversion bugs present in 2.7
177 alpha 2, including: (1) a serious 'wrong output' bug that could
178 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
179 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000180 strings corresponding to subnormal values, (3) a memory leak for
181 some values large enough to cause overflow, and (4) a number of
182 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000183
Benjamin Petersonaea44282010-01-04 01:10:28 +0000184- The __complex__ method is now looked up on the class of instances to make it
185 consistent with other special methods.

188 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
189
Benjamin Petersond12362a2009-12-30 19:44:54 +0000190- Issue #7604: Deleting an unset slotted attribute did not raise an
191 AttributeError.

Mark Dickinson9ab44b52009-12-30 16:22:49 +0000193- Issue #7534: Fix handling of IEEE specials (infinities, nans,
194 negative zero) in ** operator. The behaviour now conforms to that
195 described in C99 Annex F.
196
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000197- Issue #1811: improve accuracy and cross-platform consistency for
198 true division of integers: the result of a/b is now correctly
199 rounded for ints a and b (at least on IEEE 754 platforms), and in
200 particular does not depend on the internal representation of an int.
201
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000202- Issue #6834: replace the implementation for the 'python' and 'pythonw'
203 executables on OSX.
204
205 These executables now work properly with the arch(1) command:
206 ``arch -ppc python`` will start a universal binary version of python
207 in PPC mode (unlike previous releases).
208
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000209- Issue #7466: segmentation fault when the garbage collector is called

217
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000218- Issue #7085: Fix crash when importing some extensions in a thread
219 on MacOSX 10.6.
220
Philip Jenvey1309adb2009-11-17 03:43:14 +0000221- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.

224 implement the relevant rich comparison methods.
225
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000226- Issue #7298: fixes for range and reversed(range(...)). Iteration
227 over range(a, b, c) incorrectly gave an empty iterator when a, b and
228 c fit in C long but the length of the range did not. Also fix
229 several cases where reversed(range(a, b, c)) gave wrong results, and
230 fix a refleak for reversed(range(a, b, c)) with large arguments.
231
Raymond Hettingerfc438512009-11-01 20:55:33 +0000232- Issue #7244: itertools.izip_longest() no longer ignores exceptions

362 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
363 DeprecationWarning for float arguments passed with the 'L' format
364 code. This will become a TypeError in a future version of Python,
365 to match the behaviour of the other integer format codes.

572 would be turned into a non-blocking SSL socket).
573
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000574- Issue #5103: SSL handshake would ignore the socket timeout and block

612
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000613- Issue #4814: timeout parameter is now applied also for connections resulting
614 from PORT/EPRT commands.
615
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000616- Issue #8463: added missing reference to bztar in shutil's documentation.
617
Ronald Oussoren84151202010-04-18 20:46:11 +0000618- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
619 (as long as the user didn't specify 'automatic proxy configuration').
620
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000621- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
622 code as stated in RFC-959 at chapter 5.4.
623
Victor Stinner738446f02010-04-18 00:00:44 +0000624- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
625 surrogates.
626
Antoine Pitrou0454af92010-04-17 23:51:58 +0000627- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000628 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

632
Victor Stinner0e59cc32010-04-16 23:49:32 +0000633- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
634 the current working directory.
635

646
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000647- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
648 module now takes an optional timeout argument in seconds. Timeout support
649 relies on the system threading library, so as to avoid a semi-busy wait
650 loop.
651
Victor Stinner485fb562010-04-13 11:07:24 +0000652- Issue #8383: pickle and pickletools use surrogatepass error handler when
653 encoding unicode as utf8 to support lone surrogates and stay compatible with
654 Python 2.x and 3.0
655
R. David Murrayb2416e52010-04-12 16:58:02 +0000656- Issue #7585: difflib context and unified diffs now place a tab between
657 filename and date, conforming to the 'standards' they were originally
658 designed to follow. This improves compatibility with patch tools.
659
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000660- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
661 character sets will now consistently use a Content-Transfer-Encoding of
662 7bit rather than sometimes being marked as 8bit.
663
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000664- Issue #8375: test_distutils now checks if the temporary directory are still
665 present before it cleans them.
666

671 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
672 and `ssl.OPENSSL_VERSION_NUMBER`.
673
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000674- Add functools.total_ordering() and functools.cmp_to_key().
675
Mark Dickinson089b00c2010-04-03 15:51:03 +0000676- Issue #8257: The Decimal construct now accepts a float instance
677 directly, converting that float to a Decimal of equal value:
678
679 >>> Decimal(1.1)
680 Decimal('1.100000000000000088817841970012523233890533447265625')
681
Mark Dickinson98127c32010-04-03 11:18:52 +0000682- Issue #8294: The Fraction constructor now accepts Decimal and float
683 instances directly.
684
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000685- Issue #7279: Comparisons involving a Decimal signaling NaN now
686 signal InvalidOperation instead of returning False. (Comparisons
687 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
688 are now hashable; Decimal signaling NaNs remain unhashable.
689
690- Issue #2531: Comparison operations between floats and Decimal
691 instances now return a result based on the numeric values of the
692 operands; previously they returned an arbitrary result based on
693 the relative ordering of id(float) and id(Decimal).
694
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000695- Added a subtract() method to collections.Counter().
696
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000697- Issue #8233: When run as a script, py_compile.py optionally takes a single
698 argument `-` which tells it to read files to compile from stdin. Each line
699 is read on demand and the named file is compiled immediately. (Original
700 patch by Piotr Ożarowski).
701
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000702- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
703 form feed (0x0C) are now considered linebreaks, as specified in Unicode
704 Standard Annex #14. See issue #7643.
705 http://www.unicode.org/reports/tr14/
706
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000707- Comparisons using one of <, <=, >, >= between a complex instance and
708 a Fractions instance now raise TypeError instead of returning
709 True/False. This makes Fraction <=> complex comparisons consistent with
710 int <=> complex, float <=> complex, and complex <=> complex comparisons.
711
Antoine Pitrou39b35432010-03-23 00:25:54 +0000712- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
713 some methods (such as oss_mixer_device.fileno()) were not available.
714 Initial patch by Bertrand Janin.
715
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000716- Issue #8205: Remove the "Modules" directory from sys.path when Python is
717 running from the build directory (POSIX only).
718
Antoine Pitrou910bd512010-03-22 20:11:09 +0000719- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
720 didn't support chflags() (for example ZFS under FreeBSD). The error is
721 now silenced.
722
R. David Murrayca2edce2010-03-22 17:48:48 +0000723- Issue #7860: platform.uname now reports the correct 'machine' type
724 when Python is running in WOW64 mode on 64 bit Windows.
725
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000726- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
727 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
728 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000729
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000730- Issue #4282: Fix the main function of the profile module for a non-ASCII
731 script, open the file in binary mode and not in text mode with the default
732 (utf8) encoding.
733
Florent Xicluna54467e02010-03-21 12:29:50 +0000734- Issue #8179: Fix macpath.realpath() on a non-existing path.
735

739
Benjamin Peterson689a5582010-03-18 22:29:52 +0000740- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
741 detected.
742
Martin v. Löwis4b003072010-03-16 13:19:21 +0000743- Issue #6716/2: Backslash-replace error output in compilall.
744
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000745- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
746 with Tcl/Tk-8.5.
747
Matthias Klosec33b9022010-03-16 00:36:26 +0000748- Issue #8140: extend compileall to compile single files. Add -i option.
749
Matthias Klose82f60912010-03-15 13:46:04 +0000750- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
751 the locale.
752
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000753- The internals of the subprocess module on POSIX systems have been replaced
754 by an extension module (_posixsubprocess) so that the fork()+exec() can be
755 done safely without the possibility of deadlock in multithreaded applications.
756
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000757- subprocess.Popen now has restore_signals and start_new_session features.
758 The default of restore_signals=True is a new behavior compared to earlier
759 Python versions. This means that signals such as SIGPIPE are not ignored
760 by default in subprocesses launched by Python (Issue #1652).
761
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000762- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
763 cElementTree module is updated too.
764

772 the replacement were all bytes. Patch by Antoine Pitrou.
773
Gerhard Häringf9cee222010-03-05 15:20:03 +0000774- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
775 bugs and allows loading SQLite extensions from shared libraries.
776

Victor Stinnercee3ae82010-03-04 00:29:24 +0000780- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
781 reset also the pointer to the current pointer context.
782

790
Florent Xiclunac279ebf2010-02-27 11:31:21 +0000791- Issue #691291: codecs.open() should not convert end of lines on reading and
792 writing.
793

Thomas Heller5117b0b2010-02-23 20:25:02 +0000802- Issue #7959: ctypes callback functions are now registered correctly
Ezio Melotti8b1458b2010-02-24 16:55:43 +0000803 with the cycle garbage collector.
Thomas Heller5117b0b2010-02-23 20:25:02 +0000804

808 to be ignored only to the first file. Noted by Bogdan Opanchuk.
809
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000810- Issue #7597: curses.use_env() can now be called before initscr().
811 Noted by Kan-Ru Chen.
812
Ezio Melotti19e4acf2010-02-22 15:59:01 +0000813- Issue #7310: fix the __repr__ of os.environ to show the environment variables.

816 messages parsed by email.Parser.HeaderParser.
817
Brett Cannonef7d6722010-02-19 16:04:36 +0000818- Issue #7361: Importlib was not properly checking the number of bytes in
819 bytecode file when it was less then 8 bytes.
820
Mark Dickinson84230a12010-02-18 14:49:50 +0000821- Issue #7633: In the decimal module, Context class methods (with the
822 exception of canonical and is_canonical) now accept instances of int
823 and long wherever a Decimal instance is accepted, and implicitly
824 convert that argument to Decimal. Previously only some arguments
825 were converted.
826
R. David Murray1f449142010-02-11 00:15:05 +0000827- Issue #7835: shelve should no longer produce mysterious warnings during
828 interpreter shutdown.
829
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000830- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
831 in XML processing instructions and comments. These raw characters are
832 allowed by the XML specification, and are necessary when outputting e.g.
833 PHP code in a processing instruction. Patch by Neil Muller.
834
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000835- Issue #6233: ElementTree failed converting unicode characters to XML

845 type is specified. Patch by Brian Curtin.
846
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000847- Issue #6939: Fix file I/O objects in the `io` module to keep the original
848 file position when calling `truncate()`. It would previously change the
849 file position to the given argument, which goes against the tradition of
850 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
851
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000852- Issue #7610: Reworked implementation of the internal
853 :class:`zipfile.ZipExtFile` class used to represent files stored inside
854 an archive. The new implementation is significantly faster and can
855 be wrapped in a :class:`io.BufferedReader` object for more speedups.
856 It also solves an issue where interleaved calls to `read()` and
857 `readline()` give wrong results. Patch by Nir Aides.
858
Jesse Noller1f0b6582010-01-27 03:36:01 +0000859- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
860 allowing for a maximum number of tasks within the pool to be completed by
861 the worker before that worker is terminated, and a new one created to
862 replace it.
863
Benjamin Petersond6326642010-01-27 02:25:58 +0000864- Issue #7792: Registering non-classes to ABCs raised an obscure error.
865
Benjamin Peterson9a11a362010-01-27 01:51:29 +0000866- Issue #7785: Don't accept bytes in FileIO.write().

Ezio Melotti38f00332010-01-25 12:39:47 +0000868- Removed the functions 'verify' and 'vereq' from Lib/test/support.py.
869
Benjamin Peterson25001472010-01-25 03:37:42 +0000870- Issue #7773: Fix an UnboundLocalError in platform.linux_distribution() when

Victor Stinnere125f132010-05-15 21:04:43 +00001043 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001044 recursive locks as fast as regular non-recursive locks (previously,

Brett Cannon69194272009-07-20 04:23:48 +00001200- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
1201 loaders that allow for modules to be executed. Both importlib.abc.PyLoader
1202 and PyPycLoader inherit from this class and provide implementations in
1203 relation to other methods required by the ABCs.
1204
Brett Cannon64ef00f2009-07-20 03:19:18 +00001205- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
1206 the documentation said it did even though the code in PyLoader relied on the
1207 abstract method required by ResourceLoader.
1208

1258 algorithm with an improved 'binary-split' algorithm that uses fewer
1259 multiplications and allows many of the multiplications to be
1260 performed using plain C integer arithmetic instead of PyLong
1261 arithmetic. Also uses a lookup table for small arguments.

1280 TypeError it goes on to try the __int__ method, as described below.
1281

1476
Ezio Melotti184bdfb2010-02-18 09:37:05 +00001477- Issue #7712: test.support gained a new `temp_cwd` context manager which is
1478 now also used by regrtest to run all the tests in a temporary directory.
1479 The original CWD is saved in `support.SAVEDCWD`.
1480 Thanks to Florent Xicluna who helped with the patch.

1487 hard coded port.
R. David Murraye9e95932010-02-06 05:00:15 +00001488
R. David Murray445448c2009-12-20 17:28:31 +00001489- Issue #7376: instead of running a self-test (which was failing) when called

1493
R. David Murray596da442009-12-14 23:06:11 +00001494- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
R. David Murray83396232009-12-14 22:45:15 +00001495 instead of a hardcoded port number in test_rapid_restart.

Victor Stinnere125f132010-05-15 21:04:43 +00001497- Issue #7431: use TESTFN in test_linecache instead of trying to create a
R. David Murrayba311052009-12-04 00:09:14 +00001498 file in the Lib/test directory, which might be read-only for the
1499 user running the tests.
1500
R. David Murray35768ad2009-11-15 00:23:21 +00001501- Issue #7324: add a sanity check to regrtest argument parsing to
1502 catch the case of an option with no handler.
1503
R. David Murray7dc72cc2009-11-14 16:13:02 +00001504- Issue #7312: Add a -F flag to run the selected tests in a loop until
1505 a test fails. Can be combined with -j.
1506
Antoine Pitrou060cee22009-11-13 16:29:04 +00001507- Issue #6551: test_zipimport could import and then destroy some modules of
1508 the encodings package, which would make other tests fail further down
1509 the road because the internally cached encoders and decoders would point
1510 to empty global variables.
1511
Antoine Pitrou941ee882009-11-11 20:59:38 +00001512- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1518 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1519 between concurrent executions on the same system.
1520
Brett Cannon0ae45112009-11-05 01:17:22 +00001521- Issue #7248: In importlib.test.source.util a try/finally block did not make
1522 sure that some referenced objects actually were created in the block before
1523 calling methods on the object.
1524
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001525- Issue #7222: Make thread "reaping" more reliable so that reference
1526 leak-chasing test runs give sensible results. The previous method of
1527 reaping threads could return successfully while some Thread objects were
1528 still referenced. This also introduces a new private function:
1529 :func:`_thread._count()`.
1530
R. David Murray27144602009-10-19 15:26:16 +00001531- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1532 longer runs the risk of causing the worker thread to fail.
1533
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001534- Issue #7055: test___all__ now greedily detects all modules which have an
1535 __all__ attribute, rather than using a hardcoded and incomplete list.
1536
R. David Murray0bc11ae2009-10-18 22:18:17 +00001537- Issue #7058: Added save/restore for things like sys.argv and cwd to
1538 runtest_inner in regrtest, with warnings if the called test modifies them,
1539 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001540
Mark Dickinson2e304402009-10-04 18:43:54 +00001541- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1542
Brett Cannon3c273842009-07-20 00:14:29 +00001543- Fixed tests in importlib.test.source.test_abc_loader that were masking
1544 the proper exceptions that should be raised for missing or improper code
1545 object bytecode.
1546
Brett Cannonb49c70c2009-07-15 04:08:33 +00001547- Removed importlib's custom test discovery code and switched to
1548 unittest.TestLoader.discover().

1554
Antoine Pitroua69ba652010-01-18 21:20:53 +00001555- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were
1556 added to the `Tools/` directory. They were previously living in the
1557 sandbox.

1763
Antoine Pitroue4501852009-05-14 18:55:55 +00001764- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1765 library. This means, for example, that opening an UTF-16 text file in
1766 append mode doesn't add a BOM at the end of the file if the file isn't
1767 empty.
1768
R. David Murray74b89242009-05-13 17:33:03 +00001769- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1770 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1771 corrects a pydoc regression.
1772
R. David Murray99352742009-05-07 18:24:38 +00001773- Issue 5955: aifc's close method did not close the file it wrapped,
1774 now it does. This also means getfp method now returns the real fp.
1775
Benjamin Peterson932073a2009-05-23 16:14:33 +00001776Installation
1777------------
1778

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001816
1817Core and Builtins
1818-----------------
1819
Mark Dickinson865e01a2009-05-07 16:37:01 +00001820- Issue #5914: Add new C API function PyOS_string_to_double, and
1821 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1822
Eric Smith741191f2009-05-06 13:08:15 +00001823- Issue #3382: float.__format__, complex.__format__, and %-formatting
1824 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1825 affects nan -> NAN and inf -> INF.
1826
Mark Hammond5a607a32009-05-06 08:04:54 +00001827- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1828 in all operations, including splitdrive, split, etc. splitunc() now issues
1829 a PendingDeprecation warning.
1830
Eric Smith63376222009-05-05 14:04:18 +00001831- Issue #5920: For float.__format__, change the behavior with the
1832 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1833 to be like 'g' but with at least one decimal point and with a
1834 default precision of 12. Previously, the behavior the same but with
1835 a default precision of 6. This more closely matches str(), and
1836 reduces surprises when adding alignment flags to the empty
1837 presentation type. This also affects the new complex.__format__ in
1838 the same way.
1839
Martin v. Löwis011e8422009-05-05 04:43:17 +00001840- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1841
R. David Murrayb18500d2009-05-04 22:59:07 +00001842- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1843 shadowed by classtype's, even if it was None. property now
1844 inserts the __doc__ into the subclass instance __dict__.
1845
Antoine Pitrou244651a2009-05-04 18:56:13 +00001846- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1847 sequences. Patch by Nick Barnes and Victor Stinner.
1848
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001849- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001850
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001851- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1852 received a new method, detach(). detach() disconnects the underlying stream
1853 from the buffer or text IO and returns it.
1854
Mark Dickinson33841c32009-05-01 15:37:04 +00001855- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1856 floats with absolute value over 1e50. Also remove length
1857 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1858 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001859
Eric Smith741191f2009-05-06 13:08:15 +00001860- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001861 format(complex(1, 2./3), '.5') now produces a sensible result.
1862
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001863- Issue #5864: Fix empty format code formatting for floats so that it
1864 never gives more than the requested number of significant digits.
1865
Eric Smith6dc46f52009-04-27 20:39:49 +00001866- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1867 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1868
Eric Smithcc32a112009-04-26 21:35:14 +00001869- Issue #5835: Deprecate PyOS_ascii_formatd.
1870
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001871- Issue #4971: Fix titlecase for characters that are their own
1872 titlecase, but not their own uppercase.
1873
Benjamin Peterson193152c2009-04-25 01:08:45 +00001874- Issue #5283: Setting __class__ in __del__ caused a segfault.
1875
Mark Dickinsonad476da2009-04-23 19:14:16 +00001876- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1877 z involves nans, infs or negative zeros.
1878
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001879- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001880
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001881- Issue #1869 (and many duplicates): make round(x, n) correctly
1882 rounded for a float x, by using the decimal <-> binary conversions
1883 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1884 consistently agrees with format(x, '.2f').
1885
Benjamin Petersonae937c02009-04-18 20:54:08 +00001886- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1887 some builtin types.
1888
Eric Smith0923d1d2009-04-16 20:16:10 +00001889- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1890
Eric Smith35e84722009-04-16 20:21:28 +00001891- Issue #5515: str.format() type 'n' combined with commas and leading
1892 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001893
1894- Implement PEP 378, Format Specifier for Thousands Separator, for
1895 floats.
1896
Mark Dickinson3370cce2009-04-17 22:40:53 +00001897- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001898 1e11, not 1e12. This avoids printing 13 significant digits in
1899 situations where only 12 of them are correct. Example problem
1900 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1901 long time.)
1902
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001903- Issue #1580: On most platforms, use a 'short' float repr: for a
1904 finite float x, repr(x) now outputs a string based on the shortest
1905 sequence of decimal digits that rounds to x. Previous behaviour was
1906 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001907 Another minor difference is that the new repr switches to
1908 exponential notation at 1e16 instead of the previous 1e17; this
1909 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001910
1911 There's a new sys attribute sys.float_repr_style, which takes
1912 the value 'short' to indicate that we're using short float repr,
1913 and 'legacy' if the short float repr isn't available for one
1914 reason or another.
1915
1916 The float repr change involves incorporating David Gay's 'perfect
1917 rounding' code into the Python core (it's in Python/dtoa.c). As a
1918 secondary consequence, all string-to-float and float-to-string
1919 conversions (including all float formatting operations) will be
1920 correctly rounded on these platforms.
1921
1922 See issue 1580 discussions for details of platforms for which
1923 this change does not apply.
1924
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001925- Issue #5759: float() didn't call __float__ on str subclasses.
1926
Georg Brandlabc38772009-04-12 15:51:51 +00001927- The string.maketrans() function is deprecated; there is a new static method
1928 maketrans() on the bytes and bytearray classes. This removes confusion about
1929 the types string.maketrans() is supposed to work with, and mirrors the
1930 methods available on the str class.
1931
R. David Murraydc6da8a2009-04-09 22:16:43 +00001932- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1933 its clarity and its speed.
1934
Matthias Klose091c7b12009-04-07 13:24:27 +00001935- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1936 to avoid compiler warnings.
1937
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001938- Issue #3739: The unicode-internal encoder now reports the number of characters
1939 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00002074- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
2075
Benjamin Peterson7fe98532009-04-02 00:33:55 +00002076- Issue #5499: The 'c' code for argument parsing functions now only accepts a
2077 byte, and the 'C' code only accepts a unicode character.
2078
Georg Brandl406b3d82009-04-11 21:24:37 +00002079- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
2080 when hitting the recursion limit under certain circumstances.
2081
Brett Cannon0759dd62009-04-01 18:13:07 +00002082- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
2083
Georg Brandlab6f2f62009-03-31 04:16:10 +00002084- Fix a segfault when running test_exceptions with coverage, caused by
2085 insufficient checks in accessors of Exception.__context__.
2086
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002087- Issue #5604: non-ASCII characters in module name passed to
2088 imp.find_module() were converted to UTF-8 while the path is
2089 converted to the default filesystem encoding, causing nonsense.
2090
Benjamin Peterson09832742009-03-26 17:15:46 +00002091- Issue #5126: str.isprintable() returned False for space characters.
2092
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002093- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2094 the end sys.path, for compatibility with the system install of Python.
2095
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002096- Issue #4688: Add a heuristic so that tuples and dicts containing only
2097 untrackable objects are not tracked by the garbage collector. This can
2098 reduce the size of collections and therefore the garbage collection overhead
2099 on long-running programs, depending on their particular use of datatypes.
2100
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002101- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

2104
Mark Dickinsonbd792642009-03-18 20:06:12 +00002105- Issue #4258: Make it possible to use base 2**30 instead of base
2106 2**15 for the internal representation of integers, for performance
2107 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2108 --enable-big-digits option to configure, which overrides the
2109 default. Add sys.int_info structseq to provide information about
2110 the internal format.
2111
Mark Dickinson081dfee2009-03-18 14:47:41 +00002112- Issue #4474: PyUnicode_FromWideChar now converts characters outside
2113 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2114 and sizeof(Py_UNICODE) == 2.
2115
Eric Smith8ec90442009-03-14 12:29:34 +00002116- Issue #5237: Allow auto-numbered fields in str.format(). For

2118
Antoine Pitrou652e7072009-03-13 19:25:20 +00002119- Issue #5392: when a very low recursion limit was set, the interpreter would
2120 abort with a fatal error after the recursion limit was hit twice.
2121
Matthias Klose042f1332009-04-04 14:32:42 +00002122- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
2123 short file names.

Hye-Shik Chang944820b2009-04-02 10:33:16 +00002131- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
2132 error substitutions from non-strict codec error callbacks in
2133 incrementalencoder and StreamWriter.
2134
Georg Brandl33c28812009-04-01 23:07:29 +00002135- Issue #5656: Fix the coverage reporting when running the test suite with

2153
Brett Cannon7f6b4f82009-03-30 21:30:26 +00002154- Issue #5236: Change time.strptime() to only take strings. Didn't work with
2155 bytes already but the failure was non-obvious.
2156
Jesse Noller7af4ef82009-03-30 16:47:15 +00002157- Issue #5177: Multiprocessing's SocketListener class now uses

2164 (typically /dev/zero under Unix) could crash the interpreter.
2165
Benjamin Peterson59406a92009-03-26 17:10:29 +00002166- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
2167 io.BufferedRandom have been deprecated for removal in Python 3.2.
2168
Lars Gustäbel42e00912009-03-22 20:34:29 +00002169- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2170 forever on incomplete input. That caused tarfile.open() to hang when used
2171 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2172 partial bzip2 compressed data.
2173
Mark Dickinson79f52032009-03-17 23:12:51 +00002174- Issue #2110: Add support for thousands separator and 'n' type

2190
Mark Dickinsonae681df2009-03-21 10:26:31 +00002191- Issue #5463: In struct module, remove deprecated overflow wrapping
2192 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00002193 struct.error instead of returning b'\xff\xff\xff\xff'. The
2194 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2195 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00002222- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2223 it now forces its argument to double before testing for infinity.
2224
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002225- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2226 returns a non-number type.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002234
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002235- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002236 were suppressing all exceptions. These include list() and bytearray().

2242 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2243 evaluation loop is compiled with a new dispatch mechanism which gives
2244 speedups of up to 20%, depending on the system, on various benchmarks.

2257 type to (void *).
2258
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002259- Issue #4935: The overflow checking code in the expandtabs() method common
2260 to str, bytes and bytearray could be optimized away by the compiler, letting
2261 the interpreter segfault instead of raising an error.
2262
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002263- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2275 common cases are optimized thanks to a dedicated fast path and a moderate
2276 amount of loop unrolling.
2277
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002278- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2279 collecting the oldest generation) so that allocating lots of objects without
2280 destroying them does not show quadratic performance. Based on a proposal by
2281 Martin von Löwis at
2282 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2283
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002284- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002285 having been closed (for instance, a read() call could return some
2286 previously buffered data). Patch by Dmitry Vasiliev.
2287
Antoine Pitrou05608432009-01-09 18:53:14 +00002288- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2289 flag to work properly. Furthermore, when specifying -u, the text stdout
2290 and stderr streams have line-by-line buffering enabled (the default being
2291 to buffer arbitrary chunks of data).
2292
Raymond Hettinger35631532009-01-09 03:58:09 +00002293- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2294 instead of ints (reducing its size from 4 to 8 times thereby reducing
2295 Python's overall memory).
2296
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002297- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2298 an existing .py counterpart, override the co_filename attributes of all
2299 code objects if the original filename is obsolete (which can happen if the
2300 file has been renamed, moved, or if it is accessed through different paths).
2301 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2302
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002303- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2304 one byte. Also fixes the meaning of len() so that it returns the number of
2305 items, rather than the size in bytes.
2306
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002307- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2308
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002309- Issue #4747: When the terminal does not use utf-8, executing a script with
2310 non-ascii characters in its name could fail with a "SyntaxError: None" error.

2316 did not get collected.
2317
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002318- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2319 where the tp_hash and tp_dict slots are both NULL.
2320
Georg Brandlccc47b62008-12-28 11:44:14 +00002321- Issue #4759: None is now allowed as the first argument of
2322 bytearray.translate(). It was always allowed for bytes.translate().
2323
Skip Montanaro80072cb2008-12-23 03:51:14 +00002324- Added test case to ensure attempts to read from a file opened for writing
2325 fail.

2339 nl_langinfo is not the empty string. This was causing silent build
2340 failures on OS X.
2341
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002342- Issue #4597: Fixed several opcodes that weren't always propagating
2343 exceptions.

Antoine Pitrou08838b62009-01-21 00:55:13 +00002695- Issue #5008: When a file is opened in append mode with the new IO library,
2696 do an explicit seek to the end of file (so that e.g. tell() returns the

2981 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2982 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2983 skip the tests if DISPLAY is defined but can't be used.
2984
R. David Murraya21e4ca2009-03-31 23:16:50 +00002985- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002986 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002987 from test support, which does the conversion.
2988
Guilherme Polo9de29af2009-01-28 20:40:48 +00002989- Issue #5083: New 'gui' resource for regrtest.
