57 Linux 3.0.
58
R David Murray46346762011-07-18 21:38:54 -040059- Issue #7484: smtplib no longer puts <> around addresses in VRFY and EXPN

213
Ned Deily657b2de2011-06-28 19:51:30 -0700214- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
215 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
216 interpreter process. This could cause failures in non-Distutils subprocesses
217 and was unreliable since tests or user programs could modify the interpreter
218 environment after Distutils set it. Instead, have Distutils set the the
219 deployment target only in the environment of each build subprocess. It is
220 still possible to globally override the default by setting
221 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
222 greater or equal to the default value, the value with which the interpreter
223 was built.

R. David Murrayb7deff12011-01-30 06:21:28 +0000895- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
896 files in binary mode, using the email package's binary support to parse
897 arbitrary email messages. StringIO and text file input is deprecated,
898 and string input fails early if non-ASCII characters are used, where
899 previously it would fail when the email was processed in a later step.
900
Nick Coghlan793ee1f2011-01-30 01:24:08 +0000901- Issue #10845: Mitigate the incompatibility between the multiprocessing

903 by special casing main modules that actually *are* called __main__.py.
904
Éric Araujoac4e58e2011-01-29 20:32:11 +0000905- Issue #11045: Protect logging call against None argument.

Ned Deily806c9442011-01-29 18:43:56 +0000910- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
911 preventing a confusing hung appearance on OS X with the windows
912 obscured.
913
Ned Deily70063932011-01-29 18:29:01 +0000914- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the

924 with a None body.
925
Raymond Hettingera63a3122011-01-26 20:34:14 +0000926- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
927 keyword-only argument. The preceding positional argument was deprecated,
928 so it made no sense to add filter as a positional argument.
929
Raymond Hettinger512d2cc2011-01-25 21:32:39 +0000930- Issue #11004: Repaired edge case in deque.count().

Victor Stinnerf2e439f2011-01-23 00:11:58 +0000942- Issue #10955: zipimport uses ASCII encoding instead of cp437 to decode
Victor Stinner4ee65a92011-01-22 10:30:29 +0000943 filenames, at bootstrap, if the codec registry is not ready yet. It is still
944 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +0000945 for all file entries in the ZIP file.

953 a symbol named FSTAT.
954
Armin Ronacher8d96d772011-01-22 13:13:05 +0000955- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
956 encoding. This is the preferred encoding of PEP 3333 and the base encoding
957 of HTTP 1.1.
958
Armin Ronacher59531282011-01-22 13:44:22 +0000959- To match the behaviour of HTTP server, the HTTP client library now also
960 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
961 that for incoming headers which makes this behaviour now consistent in
962 both incoming and outgoing direction.
963

999 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
1000 translates newlines (\r\n => \n).

Georg Brandl255abdd2011-01-16 14:17:26 +00001063 continuation line in the formatted value has no leading white space and looks

1065 is made for all headers in any serialized message at serialization time. This
1066 provides protection against header injection attacks.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00001719 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001720 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

2103
Georg Brandl27a28582010-10-10 09:49:21 +00002104- All SyntaxErrors now have a column offset and therefore a caret when the error

Georg Brandl27a28582010-10-10 09:49:21 +00002113- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2114 with a non-empty format string. This is an effort to future-proof user
2115 code. If a derived class does not currently implement __format__ but later
2116 adds its own __format__, it would most likely break user code that had
2117 supplied a format string. This will be changed to a DeprecationWaring in
2118 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002120- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2121 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2122 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2123
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002124- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2125 functions from the libc caused the methods .upper() and lower() to become
2126 locale aware and created subtly wrong results.
2127
Georg Brandl27a28582010-10-10 09:49:21 +00002128- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2129 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002130
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002131- Issue #4617: Previously it was illegal to delete a name from the local
2132 namespace if it occurs as a free variable in a nested block. This limitation
2133 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2134
Georg Brandl27a28582010-10-10 09:49:21 +00002135- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2136 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2137 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2138 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002139
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002140- Issue #9757: memoryview objects get a release() method to release the
2141 underlying buffer (previously this was only done when deallocating the

Éric Araujoef777bd2010-10-05 00:04:20 +00002173- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002174 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002175 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002176 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002201 retry the select() loop instead of bailing out. This is because select() can

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002283- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002284 it possible for the user to create self-referencing ordered dictionaries which
2285 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002286 approach of using weakref proxies so that reference cycles never get created
2287 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +00002289- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002293- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2294 environment variable to set the filesystem encoding at Python startup.
2295 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2296 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002302- The pprint module now supports printing OrderedDicts in their given order

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002312- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2313 still return the id of the parent process after it has exited. This process
2314 id may even have been reused by another unrelated process.
2315
Georg Brandl27a28582010-10-10 09:49:21 +00002316- Issue #9792: In case of connection failure, socket.create_connection() would
2317 swallow the exception and raise a new one, making it impossible to fetch the

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002325- Updates to the random module:
2326
Georg Brandl27a28582010-10-10 09:49:21 +00002327 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002330 * Update the seed() method to use all of the bits in a string instead of just
2331 the hash value. This makes better use of the seed value and assures the
2332 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002333
Georg Brandl27a28582010-10-10 09:49:21 +00002334 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2335 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2336 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002337
2338 * Improved documentation of arguments to randrange(). Issue #9379.

2359 guaranteed to exist in all Python implementations and the names of hash
2360 algorithms available in the current process.

2489 return characters from the full Unicode range, even on narrow unicode builds
2490 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2491 in Python is that unicodedata.numeric() now returns the correct value for
2492 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00002511 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2512 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00002518- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2519 use PyUnicode_FromFormatV() to format the warning message.

2527 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002528
Georg Brandl649971e2010-09-05 17:06:50 +00002529- Issue #9416: Fix some issues with complex formatting where the output with no
2530 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002531
2532 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2533 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

2871
Ezio Melotti57221d02010-07-01 07:32:02 +00002872- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002873 start byte and the continuation byte(s) are now considered invalid, instead of
2874 the number of bytes specified by the start byte. E.g.:
2875 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2876 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2877 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2878 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00002879
Georg Brandl62069d32010-07-31 08:56:11 +00002880- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
2881 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00002882
Benjamin Peterson88968ad2010-06-25 19:30:21 +00002883- Be more specific in error messages about positional arguments.

Georg Brandl62069d32010-07-31 08:56:11 +00002892- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
2893 dealing with unary minus applied to a constant. The removed code was mutating
2894 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00002895
Victor Stinner554f3f02010-06-16 23:33:54 +00002896- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00002897 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00002898 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002899 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002900
Victor Stinner25e8ec42010-06-25 00:02:38 +00002901- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use

2903
Victor Stinner06e49dd2010-06-13 18:21:50 +00002904- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00002905 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00002906 string formats.
2907
Georg Brandl62069d32010-07-31 08:56:11 +00002908- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002909 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2910 location of the raised exception.
2911
Victor Stinner313a1202010-06-11 23:56:51 +00002912- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2913 filenames and enable os.fsencode().
2914
Benjamin Peterson285a6892010-06-22 19:21:52 +00002915- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2916
Georg Brandl62069d32010-07-31 08:56:11 +00002917- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2918 interpreter with characters outside the Basic Multilingual Plane (higher than
2919 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00002920
Georg Brandl62069d32010-07-31 08:56:11 +00002921- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2922 TypeError instead of giving a DeprecationWarning when a float is parsed using
2923 the 'L' code (for long long). (All other integer codes already raise
2924 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002925
Victor Stinner600d3be2010-06-10 12:00:55 +00002926- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2927 enable shortcuts for upper case encoding name. Add also a shortcut for
2928 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2929
Georg Brandl62069d32010-07-31 08:56:11 +00002930- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2931 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002932
2933- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002934 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002935 like bytearray.
2936
Georg Brandl62069d32010-07-31 08:56:11 +00002937- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002938 used anymore and it was never documented.
2939
Georg Brandl62069d32010-07-31 08:56:11 +00002940- In str.format(), raise a ValueError when indexes to arguments are too large.

Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002944
Georg Brandl62069d32010-07-31 08:56:11 +00002945- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2946 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2947 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2948 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002949
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002950- Issue #8748: Fix two issues with comparisons between complex and integer
2951 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002952 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2953 (2) The comparison raised an OverflowError for large integers, leading to
2954 unpredictable exceptions when combining integers and complex objects in sets
2955 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002956

2959
Victor Stinner9ca9c252010-05-19 16:53:30 +00002960- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002961 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002962 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00002963
Georg Brandl62069d32010-07-31 08:56:11 +00002964- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2965 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002966
Victor Stinnerae6265f2010-05-15 16:27:27 +00002967- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2968 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002969 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002970 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00002971
Victor Stinner59e62db2010-05-15 13:14:32 +00002972- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00002973 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00002974
Victor Stinnerb744ba12010-05-15 12:27:16 +00002975- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00002976 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00002977 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
2978
Victor Stinner0964ee12010-04-30 16:48:45 +00002979- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00002980 PyUnicode_FromString() to support surrogates in the filename and use the right
2981 encoding.

3082 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003084- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003085 where the right hand operand is a set of constants, by turning the set into a
3086 frozenset and pre-building it as a constant. The comparison operation is made
3087 against the constant instead of building a new set each time it is executed (a
3088 similar optimization already existed which turned a list of constants into a
3089 pre-built tuple). Patch and additional tests by Dave Malcolm.

3096 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3097 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3098 parsing certain long numeric strings corresponding to subnormal values, (3) a
3099 memory leak for some values large enough to cause overflow, and (4) a number
3100 of flaws that could lead to incorrectly rounded results.

3116 least on IEEE 754 platforms), and in particular does not depend on the
3117 internal representation of an int.

3395 the performance hit anytime the cache is exceeded.

R. David Murrayb2416e52010-04-12 16:58:02 +00003775- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00003776 filename and date, conforming to the 'standards' they were originally designed
3777 to follow. This improves compatibility with patch tools.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00003793- Add functools.total_ordering() and functools.cmp_to_key().
3794
Georg Brandl62069d32010-07-31 08:56:11 +00003795- Issue #8257: The Decimal construct now accepts a float instance directly,
3796 converting that float to a Decimal of equal value:

3798 >>> Decimal(1.1)
3799 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00003804- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3805 InvalidOperation instead of returning False. (Comparisons involving a quiet
3806 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3807 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003808
Georg Brandl62069d32010-07-31 08:56:11 +00003809- Issue #2531: Comparison operations between floats and Decimal instances now
3810 return a result based on the numeric values of the operands; previously they
3811 returned an arbitrary result based on the relative ordering of id(float) and
3812 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3813 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003814
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003815- Added a subtract() method to collections.Counter().
3816
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003817- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003818 argument `-` which tells it to read files to compile from stdin. Each line is
3819 read on demand and the named file is compiled immediately. (Original patch by
3820 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00003822- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3823 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00003824 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00003826- Comparisons using one of <, <=, >, >= between a complex instance and a
3827 Fractions instance now raise TypeError instead of returning True/False. This
3828 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3829 <=> complex, and complex <=> complex comparisons.

3837
Antoine Pitrou910bd512010-03-22 20:11:09 +00003838- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00003839 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00003872- The internals of the subprocess module on POSIX systems have been replaced by
3873 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3874 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003875
Georg Brandl62069d32010-07-31 08:56:11 +00003876- subprocess.Popen now has restore_signals and start_new_session features. The
3877 default of restore_signals=True is a new behavior compared to earlier Python
3878 versions. This means that signals such as SIGPIPE are not ignored by default
3879 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00003880

3966 position when calling `truncate()`. It would previously change the file
3967 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00003968 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3972 archive. The new implementation is significantly faster and can be wrapped in
3973 a :class:`io.BufferedReader` object for more speedups. It also solves an
3974 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004372- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004373 compared to other unix systems. In particular, os.getgroups() does not reflect

4376 groups on MacOSX.

4732 threads could return successfully while some Thread objects were still
4733 referenced. This also introduces a new private function:

4741
R. David Murray0bc11ae2009-10-18 22:18:17 +00004742- Issue #7058: Added save/restore for things like sys.argv and cwd to

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005020
5021Core and Builtins
5022-----------------
5023
Mark Dickinson865e01a2009-05-07 16:37:01 +00005024- Issue #5914: Add new C API function PyOS_string_to_double, and
5025 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5026
Eric Smith741191f2009-05-06 13:08:15 +00005027- Issue #3382: float.__format__, complex.__format__, and %-formatting
5028 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5029 affects nan -> NAN and inf -> INF.
5030
Mark Hammond5a607a32009-05-06 08:04:54 +00005031- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5032 in all operations, including splitdrive, split, etc. splitunc() now issues
5033 a PendingDeprecation warning.
5034
Eric Smith63376222009-05-05 14:04:18 +00005035- Issue #5920: For float.__format__, change the behavior with the
5036 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5037 to be like 'g' but with at least one decimal point and with a
5038 default precision of 12. Previously, the behavior the same but with
5039 a default precision of 6. This more closely matches str(), and
5040 reduces surprises when adding alignment flags to the empty
5041 presentation type. This also affects the new complex.__format__ in
5042 the same way.
5043
Martin v. Löwis011e8422009-05-05 04:43:17 +00005044- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5045
R. David Murrayb18500d2009-05-04 22:59:07 +00005046- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5047 shadowed by classtype's, even if it was None. property now
5048 inserts the __doc__ into the subclass instance __dict__.
5049
Antoine Pitrou244651a2009-05-04 18:56:13 +00005050- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5051 sequences. Patch by Nick Barnes and Victor Stinner.
5052
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005053- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005054
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005055- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5056 received a new method, detach(). detach() disconnects the underlying stream
5057 from the buffer or text IO and returns it.
5058
Mark Dickinson33841c32009-05-01 15:37:04 +00005059- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5060 floats with absolute value over 1e50. Also remove length
5061 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5062 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005063
Eric Smith741191f2009-05-06 13:08:15 +00005064- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005065 format(complex(1, 2./3), '.5') now produces a sensible result.
5066
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005067- Issue #5864: Fix empty format code formatting for floats so that it
5068 never gives more than the requested number of significant digits.
5069
Eric Smith6dc46f52009-04-27 20:39:49 +00005070- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5071 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5072
Eric Smithcc32a112009-04-26 21:35:14 +00005073- Issue #5835: Deprecate PyOS_ascii_formatd.
5074
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005075- Issue #4971: Fix titlecase for characters that are their own
5076 titlecase, but not their own uppercase.
5077
Benjamin Peterson193152c2009-04-25 01:08:45 +00005078- Issue #5283: Setting __class__ in __del__ caused a segfault.
5079
Mark Dickinsonad476da2009-04-23 19:14:16 +00005080- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5081 z involves nans, infs or negative zeros.
5082
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005083- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005084
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005085- Issue #1869 (and many duplicates): make round(x, n) correctly
5086 rounded for a float x, by using the decimal <-> binary conversions
5087 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5088 consistently agrees with format(x, '.2f').
5089
Benjamin Petersonae937c02009-04-18 20:54:08 +00005090- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5091 some builtin types.
5092
Eric Smith0923d1d2009-04-16 20:16:10 +00005093- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5094
Eric Smith35e84722009-04-16 20:21:28 +00005095- Issue #5515: str.format() type 'n' combined with commas and leading
5096 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005097
5098- Implement PEP 378, Format Specifier for Thousands Separator, for
5099 floats.
5100
Mark Dickinson3370cce2009-04-17 22:40:53 +00005101- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005102 1e11, not 1e12. This avoids printing 13 significant digits in
5103 situations where only 12 of them are correct. Example problem
5104 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5105 long time.)
5106
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005107- Issue #1580: On most platforms, use a 'short' float repr: for a
5108 finite float x, repr(x) now outputs a string based on the shortest
5109 sequence of decimal digits that rounds to x. Previous behaviour was
5110 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005111 Another minor difference is that the new repr switches to
5112 exponential notation at 1e16 instead of the previous 1e17; this
5113 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005114
5115 There's a new sys attribute sys.float_repr_style, which takes
5116 the value 'short' to indicate that we're using short float repr,
5117 and 'legacy' if the short float repr isn't available for one
5118 reason or another.
5119
5120 The float repr change involves incorporating David Gay's 'perfect
5121 rounding' code into the Python core (it's in Python/dtoa.c). As a
5122 secondary consequence, all string-to-float and float-to-string
5123 conversions (including all float formatting operations) will be
5124 correctly rounded on these platforms.
5125
Georg Brandl5f90d792010-08-01 22:31:05 +00005126 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005127 this change does not apply.
5128
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005129- Issue #5759: float() didn't call __float__ on str subclasses.
5130
Georg Brandlabc38772009-04-12 15:51:51 +00005131- The string.maketrans() function is deprecated; there is a new static method
5132 maketrans() on the bytes and bytearray classes. This removes confusion about
5133 the types string.maketrans() is supposed to work with, and mirrors the
5134 methods available on the str class.
5135
R. David Murraydc6da8a2009-04-09 22:16:43 +00005136- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5137 its clarity and its speed.
5138
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005139- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005140 to avoid compiler warnings.
5141
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005142- Issue #3739: The unicode-internal encoder now reports the number of characters
5143 consumed like any other encoder (instead of the number of bytes).

Guido van Rossum0ad59d42009-03-30 22:01:35 +00005293- Issue #5604: non-ASCII characters in module name passed to
5294 imp.find_module() were converted to UTF-8 while the path is
5295 converted to the default filesystem encoding, causing nonsense.
5296
Benjamin Peterson09832742009-03-26 17:15:46 +00005297- Issue #5126: str.isprintable() returned False for space characters.
5298
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005299- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5300 the end sys.path, for compatibility with the system install of Python.
5301
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005302- Issue #4688: Add a heuristic so that tuples and dicts containing only
5303 untrackable objects are not tracked by the garbage collector. This can
5304 reduce the size of collections and therefore the garbage collection overhead
5305 on long-running programs, depending on their particular use of datatypes.
5306
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005307- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
5308 improve its performance. Long divisions and remainder operations
5309 are now between 50% and 150% faster.
5310
Mark Dickinsonbd792642009-03-18 20:06:12 +00005311- Issue #4258: Make it possible to use base 2**30 instead of base
5312 2**15 for the internal representation of integers, for performance
5313 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5314 --enable-big-digits option to configure, which overrides the
5315 default. Add sys.int_info structseq to provide information about
5316 the internal format.
5317
Mark Dickinson081dfee2009-03-18 14:47:41 +00005318- Issue #4474: PyUnicode_FromWideChar now converts characters outside
5319 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5320 and sizeof(Py_UNICODE) == 2.
5321
Eric Smith8ec90442009-03-14 12:29:34 +00005322- Issue #5237: Allow auto-numbered fields in str.format(). For
5323 example: '{} {}'.format(1, 2) == '1 2'.
5324
Antoine Pitrou652e7072009-03-13 19:25:20 +00005325- Issue #5392: when a very low recursion limit was set, the interpreter would
5326 abort with a fatal error after the recursion limit was hit twice.
5327
Matthias Klose042f1332009-04-04 14:32:42 +00005328- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
5329 short file names.

5361 bytes already but the failure was non-obvious.
5362
Jesse Noller7af4ef82009-03-30 16:47:15 +00005363- Issue #5177: Multiprocessing's SocketListener class now uses

5374
Lars Gustäbel42e00912009-03-22 20:34:29 +00005375- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5376 forever on incomplete input. That caused tarfile.open() to hang when used
5377 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5378 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00005399 struct.error instead of returning b'\xff\xff\xff\xff'. The
5400 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

5417 used when using str.format() with str, int, and float arguments.
5418
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005419- Issue #5249: time.strftime returned malformed string when format string
5420 contained non ascii character on windows.
5421
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005422- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5423 source has already been decoded into str.
5424
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005425- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5426 rotating the object pointer by 4 bits to the right.
5427
Mark Dickinson87ec0852009-02-09 17:15:59 +00005428- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5429 it now forces its argument to double before testing for infinity.
5430
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005431- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5432 returns a non-number type.
5433
Benjamin Peterson87618552009-02-08 15:00:52 +00005434- Issue #5182: Removed memoryview.__str__.
5435
Mark Dickinsonc008a172009-02-01 13:59:22 +00005436- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5437 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005438 the type definition cmpfunc. The tp_compare slot has been renamed
5439 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005440
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005441- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005442 were suppressing all exceptions. These include list() and bytearray().
5443
Mark Dickinson1124e712009-01-28 21:25:58 +00005444- Issue #4707: round(x, n) now returns an integer if x is an integer.
5445 Previously it returned a float.
5446
Antoine Pitroub52ec782009-01-25 16:34:23 +00005447- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5448 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5449 evaluation loop is compiled with a new dispatch mechanism which gives
5450 speedups of up to 20%, depending on the system, on various benchmarks.
5451
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005452- Issue #4874: Most builtin decoders now reject unicode input.

5458
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005459- Issue #4838: When a module is deallocated, free the memory backing the
5460 optional module state data.
5461
Mark Dickinson8055afd2009-01-17 10:04:45 +00005462- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005463 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005464
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005465- Issue #4935: The overflow checking code in the expandtabs() method common
5466 to str, bytes and bytearray could be optimized away by the compiler, letting
5467 the interpreter segfault instead of raising an error.
5468
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005469- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5470 __next__ method.
5471
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005472- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5473 function no longer attempt to call the __long__ slot to convert an object
5474 to an integer. Only the __int__ and __trunc__ slots are examined.
5475
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005476- Issue #4893: Use NT threading on CE.

5479
Antoine Pitrouab868312009-01-10 15:40:25 +00005480- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5481 common cases are optimized thanks to a dedicated fast path and a moderate
5482 amount of loop unrolling.
5483
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005484- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5485 collecting the oldest generation) so that allocating lots of objects without
5486 destroying them does not show quadratic performance. Based on a proposal by
5487 Martin von Löwis at
5488 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5489
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005490- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005491 having been closed (for instance, a read() call could return some
5492 previously buffered data). Patch by Dmitry Vasiliev.
5493
Antoine Pitrou05608432009-01-09 18:53:14 +00005494- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5495 flag to work properly. Furthermore, when specifying -u, the text stdout
5496 and stderr streams have line-by-line buffering enabled (the default being
5497 to buffer arbitrary chunks of data).
5498
Raymond Hettinger35631532009-01-09 03:58:09 +00005499- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5500 instead of ints (reducing its size from 4 to 8 times thereby reducing
5501 Python's overall memory).
5502
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005503- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5504 an existing .py counterpart, override the co_filename attributes of all
5505 code objects if the original filename is obsolete (which can happen if the
5506 file has been renamed, moved, or if it is accessed through different paths).
5507 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5508
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005509- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5510 one byte. Also fixes the meaning of len() so that it returns the number of
5511 items, rather than the size in bytes.
5512
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005513- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5514
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005515- Issue #4747: When the terminal does not use utf-8, executing a script with
5516 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5517
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005518- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5519 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005520
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005521- Issue #3680: Reference cycles created through a dict, set or deque iterator
5522 did not get collected.
5523
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005524- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5525 where the tp_hash and tp_dict slots are both NULL.
5526
Georg Brandlccc47b62008-12-28 11:44:14 +00005527- Issue #4759: None is now allowed as the first argument of
5528 bytearray.translate(). It was always allowed for bytes.translate().
5529
Skip Montanaro80072cb2008-12-23 03:51:14 +00005530- Added test case to ensure attempts to read from a file opened for writing
5531 fail.
5532
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005533- Issue #3106: Speedup some comparisons (str/str and int/int).

5536 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5537
Antoine Pitrou621601a2008-12-17 23:18:19 +00005538- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5539 print elapsed times, not only when some objects are uncollectable /
5540 unreachable. Original patch by Neil Schemenauer.
5541
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005542- Issue #3439: Add a bit_length method to int.
5543
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005544- Issue #2173: When getting device encoding, check that return value of
5545 nl_langinfo is not the empty string. This was causing silent build
5546 failures on OS X.
5547
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005548- Issue #4597: Fixed several opcodes that weren't always propagating
5549 exceptions.
5550
5551- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005552 context manager returns a value that cannot be converted to a bool.
5553
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005554- Issue #4445: Replace "sizeof(PyBytesObject)" with
5555 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5556 bytes instances. On a typical machine this saves 3 bytes of memory
5557 (on average) per allocation of a bytes instance.
5558
Christian Heimesa872de52008-12-05 08:26:55 +00005559- Issue #4533: File read operation was dreadfully slow due to a slowly
5560 growing read buffer. Fixed by using the same growth rate algorithm as
5561 Python 2.x.
5562
Antoine Pitrou5504e892008-12-06 21:27:53 +00005563- Issue #4509: Various issues surrounding resize of bytearray objects to
5564 which there are buffer exports (e.g. memoryview instances).
5565
Georg Brandlf9734072008-12-07 15:30:06 +00005566- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5567 method on file objects with closefd=False. The file descriptor is still
5568 kept open but the file object behaves like a closed file. The ``FileIO``
5569 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005570
Antoine Pitroubc420402008-12-07 20:14:49 +00005571- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5572 larger than 1.
5573

5902 do an explicit seek to the end of file (so that e.g. tell() returns the
5903 file size rather than 0). This is consistent with the behaviour of the

5934 appropriately when it is being used via socket.makefile() objects
5935 rather than delaying the close by waiting for garbage collection to do it.
5936
Raymond Hettingerb8baf632009-01-14 02:20:07 +00005937- Issue #1696199: Add collections.Counter() for rapid and convenient

6149 supporting objects as input no matter how it was compiled (built in
6150 implementations or external openssl library).
6151
Mark Dickinson29500f62009-01-15 15:36:10 +00006152- Issue #4397: Fix occasional test_socket failure on OS X.

6155
Antoine Pitroubcd5cbe2009-01-08 21:17:16 +00006156- Issue #4751: hashlib now releases the GIL when hashing large buffers
6157 (with a hardwired threshold of 2048 bytes), allowing better parallelization
6158 on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.
6159
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006160- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
6161
Antoine Pitrou31f30b12009-01-02 17:34:35 +00006162- Issue #4738: Each zlib object now has a separate lock, allowing to compress
6163 or decompress several streams at once on multi-CPU systems. Also, the GIL
6164 is now released when computing the CRC of a large buffer. Patch by ebfe.
6165
Georg Brandlb1441c72009-01-03 22:33:39 +00006166- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.

6171 OpenBSD.
Amaury Forgeot d'Arcefae8c42008-11-21 23:08:09 +00006172
Antoine Pitrou3ad3a0d2008-12-18 17:08:32 +00006173- Issue #4583: array.array would not always prohibit resizing when a buffer
6174 has been exported, resulting in an interpreter crash when accessing the
6175 buffer.
6176
Martin v. Löwis841edad2008-11-30 10:36:49 +00006177
Jack Diederiche0cbd692009-04-01 04:27:09 +00006178- Issue #5228: Make functools.partial objects can now be pickled.

6182
Antoine Pitrou88909542009-06-29 13:54:42 +00006183- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6184 regression tests in parallel, shortening the total runtime.
6185
Guilherme Polo2a998fa2009-06-21 17:40:07 +00006186- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6187 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6188 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6189 skip the tests if DISPLAY is defined but can't be used.
6190
R. David Murraya21e4ca2009-03-31 23:16:50 +00006191- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006192 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006193 from test support, which does the conversion.
6194
Guilherme Polo9de29af2009-01-28 20:40:48 +00006195- Issue #5083: New 'gui' resource for regrtest.
